ABSTRACT

Abstract

The direction of sunlight is tracked according to variations of the altitude of the sun to maximize condensing efficiency. An apparatus for tracking and condensing sunlight includes a horizontal truss, a roof truss forming a triangular structure inclined to both sides of the horizontal truss, and a hinge formed on a top of the roof truss. Solar module plates are formed on both inclined surfaces of the roof truss to condense sunlight and interoperate with each other in a lateral direction. A driving means supports lower portions of the solar module plates, and moves the lower portions thereof so the solar module plates can pivot in both left and right directions around the hinge. The apparatus tracks sunlight and pivots the solar module plates to maximize condensing efficiency, improves energy production efficiency by using a roof area, and firmly fixes the solar module plate to the roof.

Description

TECHNICAL FIELD

The present invention relates to an apparatus for condensing sunlight of a roof installation type, and more particularly, to an apparatus for two-way tracing and condensing sunlight of a roof installation type which traces a direction of sunlight according to variations of an altitude or orbit of the sun, pivots a solar module plate to maximize condensing efficiency, and strengthens a roof fixing structure thereof.

BACKGROUND ART

In general, sunlight generation indicates a generation method for converting sunlight directly into electric power via a solar battery.

As compared with other types of generation, solar energy generation generates clean energy without air pollution, noise, heat generation, vibration, etc., seldom requires fuel transfer and maintenance and management of generation equipment, increases a lifespan of an apparatus, and simplifies decision of an equipment scale and installation works.

A sunlight generation system has advantages in that an energy source is clean and infinite, and the generation system is easily maintained and repaired, can be implemented into a unmanned system and has a long lifespan.

FIG. 1 shows a conventional apparatus for condensing sunlight of a fixed type. The conventional apparatus has the cheapest stable structure, and is mostly used in a comparatively remote region where an installation area is not limited. Particularly, the conventional apparatus is normally installed in an island of a strong wind velocity. The conventional apparatus adopts an array supporting method relatively often used because initial installation. costs are small and no difficulty occurs in repair and management. A domestic sunlight system for an island has been standardized as the fixed type system.

In addition, there may be used an apparatus for two-way condensing sunlight of a fixed type, wherein the foregoing fixed type structures are installed in both directions.

However, since the conventional apparatus for condensing sunlight of the fixed type is fixedly installed to face one direction, when sunlight is optimally condensed on one surface, sunlight efficiency is reduced on the other opposite surface. As a result, condensing efficiency of the overall system is lowered according to variations of an altitude or orbit of sunlight.

Moreover, since the conventional apparatus is installed mostly on the ground, an installation place thereof is limitative. When the conventional apparatus is installed on the roof or rooftop, it is weak to wind or load.

SUMMARY OF THE INVENTION

Accordingly, the present invention is conceived to solve the aforementioned problems in the prior art. An object of the present invention is to provide an apparatus for two-way tracing and condensing sunlight of a roof installation type which traces a direction of sunlight according to variations of an altitude or orbit of the sun and pivots a solar module plate so as to maximize condensing efficiency.

In addition, another object of the present invention is to improve environment-friendly energy production efficiency using a roof area which is a unnecessary space without requiring a large ground area by implementing a roof installation type on the roof of a building, and to provide a structure strong against wind or load by firmly fixing a means for fixing and pivoting a solar module plate to the roof.

FIG. 2 is a side view illustrating an apparatus for two-way tracing and condensing sunlight of a roof installation type according to the present invention, and FIG. 3 is a plane view of FIG. 2 .

As illustrated in the drawings, the apparatus for two-way tracing and condensing sunlight of the roof installation type according to the present invention includes a light tracing and driving controller ( 100 ; refer to FIG. 6 ), a first solar module plate 201 , an open hinge 102 , a first open push rod 203 , a horizontal truss 105 , a gutter beam 110 , a pillar 114 , a roof truss 115 , a gutter 116 , an auxiliary pillar truss 118 , a roof member 119 , a through hole 120 , a first driven pipe 204 , a first rack pinion 206 , a pipe roller 207 , a first driving pipe 208 , a first push rod hinge 209 , a rack pinion support beam 212 , a first motor 213 , a second solar module plate 401 , a second open push rod 403 , a second driven pipe 404 , a second rack pinion 406 , a pipe roller 407 , a second driving pipe 408 , a second push rod hinge 409 , a rack pinion support beam 412 , and a second motor 413 .

As illustrated in FIG. 6 , the light tracing and driving controller 100 described below is installed on the roof member 119 to trace an orbit or altitude of the sun. For example, the light tracing and driving controller 100 is attached with two or more optical sensors (not shown), and traces a point where amounts of light entering the two or more optical sensors are the same, to thereby ensure maximum energy efficiency. Since it can be easily constructed according to the well-known prior art, detailed explanation thereof is omitted.

The horizontal truss 105 has a structure of a horizontal direction. The horizontal truss 105 may be formed on a special pillar 114 or auxiliary pillar 118 .

The roof truss 115 forms a triangular roof on the horizontal truss 105 . That is, the roof truss 115 forms a triangular structure inclined to both sides on the horizontal truss 105 in a plural number, and forms the roof member 119 thereon.

The horizontal truss 105 and the roof truss 115 constitute a building with a general triangular roof.

In addition, the open hinge 102 is formed on a top end of the roof truss 115 to be extended in a lateral direction, and arranged in a vertical direction in a plural number.

The first solar module plate 201 and the second solar module plate 401 are formed on both inclined surfaces outside the roof truss 115 respectively to condense sunlight, and upper portions thereof are pivotably coupled to the open hinge 102 in both directions. Here, the first solar module plate 201 and the second solar module plate 401 are brought into surface-contact with each other on the left and right sides, and installed in a plural number to interoperate with each other in a lateral direction.

In addition, the driving means of the present invention supports lower portions of the plurality of first solar module plates 201 and second solar module plates 401 , and pushes or pulls the lower portions thereof so that the plurality of first solar module plates 201 and second solar module plates 401 can pivot individually or together in both left and right directions around the hinges.

Particularly, the first solar module plates 201 and the second solar module plates 401 preferably pivot from the east to the west according to a traveling direction of the sun.

To this end, the driving means includes the first motor 213 , the first driving pipe 208 , the plurality of first rack pinions 206 , the plurality of first driven pipes 204 , the plurality of first open push rods 203 , the second motor 413 , the second driving pipe 408 , the plurality of second rack pinions 406 , the plurality of second driven pipes 404 , and the plurality of second open push rods 403 .

The first driving pipe 208 is extended in a lateral direction to rotate with the first motor 213 , and the plurality of first rack pinions 206 are connected to the first driving pipe 208 to convert a rotational motion of the first motor 213 into a linear motion.

The plurality of first driven pipes 204 are coupled to the plurality of first rack pinions 206 to perform a linear motion in the front-rear direction.

The plurality of first open push rods 203 have one sides hinge-coupled to the plurality of first driven pipes 204 side by side to move horizontally, and the other sides hinge-coupled to the lower portions of the plurality of first solar module plates 201 respectively to lift the first solar module plates 201 in the front up-down direction.

To this end, the roof member 119 has a plurality of through holes 120 formed therein so that the plurality of first open push rods 203 and second open push rods 403 can pass therethrough.

Moreover, the first open push rod 203 and the second open push rod 403 are formed in the shape of a bracket such that they are connected to four points of the first and second solar module plates

201 and 401 and one point of the first and second driven pipes

204 and 404 , respectively.

The second driving pipe 408 is extended in a lateral direction to rotate with the second motor 413 , and the plurality of second rack pinions 406 are connected to the second driving pipe 408 to convert a rotational motion of the second motor 413 into a linear motion.

The plurality of second driven pipes 404 are coupled to the plurality of second rack pinions 404 to perform a linear motion in the front-rear direction.

The plurality of second open push rods 403 have one sides hinge-coupled to the plurality of second driven pipes 404 side by side to move horizontally, and the other sides hinge-coupled to the lower portions of the plurality of second solar module plates 401 respectively to lift the second solar module plates 401 in the rear up-down direction.

Here, the first motor 213 and the second motor 413 , which produce a rotational force, may be provided with a reduction gear (not shown) for example, or implemented into worm geared motors including a built-in reduction gear. Preferably, the first motor 213 and the second motor 413 may rotate normally and reversely according to a size of a signal output from the light tracing and driving controller 100 discussed later.

As described above, the first solar module plate 201 condenses sunlight in a state where the upper portion thereof is pivotably hinge-fixed to the top end of the roof truss 115 , and one side of the first open push rod 203 supports the lower portion of the first solar module plate 201 . Further, the first pivoting means 200 fixes the other side of the first open push rod 203 , and pushes or pulls the first open push rod 203 to pivot the first solar module plate 201 according to the orbit or altitude of the sun traced by the light tracing and driving controller 100 .

Accordingly, when the first motor 213 rotates, the first driven pipe 204 moves in the front-rear direction. As the first driven pipe 204 moves in the front-rear direction, the first open push rod 203 pushes or pulls the lower portion of the first solar module plate 201 to change an angle of the first solar module plate 201 . As a result, the first solar module plate 201 can always maintain an optimum angle to condense sunlight according to the orbit or altitude of the sun traced by the light tracing and driving controller 100 .

Meanwhile, the second solar module plate 401 condenses sunlight in a state where the upper portion thereof is pivotably hinge-fixed to the top end of the roof truss 115 , and is formed in the opposite side to the first solar module plate 201 .

One side of the second open push rod 403 supports the lower portion of the second solar module plate 401 . Furthermore, the second pivoting means 400 fixes the other side of the second open push rod 403 , and pushes or pulls the second open push rod 403 to pivot the second solar module plate 401 according to the orbit or altitude of the sun traced by the light tracing and driving controller 100 .

Here, the first solar module plate 201 and the second solar module plate 401 are preferably installed in the east-west direction. Therefore, the first solar module plate 201 and the second solar module plate 401 are pivoted according to a traveling orbit or altitude of the sun, thereby condensing sunlight in optimum state.

Accordingly, the apparatus of the present invention can condense sunlight through the first solar module plate 201 and the second solar module plate 401 , always maintaining an optimum angle according to the orbit or altitude of the sun traced by the light tracing and driving controller 100 .
