Today, energy consumption in countries around the world including Korea is increasing every year, and greenhouse gas emissions from energy use are also rapidly increasing in proportion to energy consumption. Therefore, the development of eco-friendly alternative energy has been a major concern in each country's energy retention policy for a long time, and the necessity and importance of alternative energy development is increasing as the years go by. In keeping with this, in recent years, among alternative energies, energy technology development using solar energy, which is pollution-free and relatively easy to secure an energy source, has been actively researched and used.

This solar energy is a technology that directly converts sunlight into electrical energy (photoelectric effect), and is composed of a solar cell module, a controller, a battery, an inverter, a controller, etc. It is possible to use an unlimited number of clean energy sources.

In this way, for solar power generation, structures and module clamps for installing solar cell modules are required, and the above structures or module clamps take a long period of about 20 to 30 years to stably install solar cell modules. Durability that can withstand and a solid coupling structure are essential.

In the city, there was a problem in that sunlight on the ground was completely blocked by the solar module.

In order to prevent this problem, the length of the vertical frame supporting the solar module should be secured so that the solar module can be sufficiently separated from the ground and inserted and fixed to the ground by a sufficient depth. In order to reinforce the strength, the thickness of the vertical frame is also inevitably increased, resulting in an increase in manufacturing cost.

In addition, when the solar power generation system is installed on the slope of the forest field, cutting or filling of the slope must be performed first, but the environment is destroyed due to such cutting or filling work, and the loss of soil on the ground surface during the rainy season. In this case, there is a problem that a collapse accident of the solar power generation device is concerned, and enormous working time, manpower, and cost are consumed for cutting or filling work.

Hereinafter, the construction structure of the solar power generation device according to the present invention will be described in more detail with reference to the accompanying drawings.

In the present invention, when a solar power generation device is installed on a slope of a forest field, cutting or filling of the slope can be omitted, and through this, the environment can be protected and the working time, manpower, and cost can be significantly reduced. A construction structure of a photovoltaic device is disclosed.

For the above purpose, the present invention provides a telephone pole 100 installed on a sloped slope 10 of a forest field, a fixing bracket 200 coupled to the telephone pole, and a module support frame 300 coupled to the fixing bracket, and It includes a truss structure 400 for supporting the solar module and the module support frame.

First, the telephone pole 100 is manufactured using concrete as a raw material, and is a structure perpendicular to the ground to connect electric wires or telephone lines for providing electric power or communication services, and is typically formed in a length of 6m to 16m.

The telephone poles 100 are arranged and installed in plural at regular intervals along the inclined surface 10.

Conventionally, assuming that a photovoltaic power generation device is installed on an irregular slope as shown in FIG. 1, the slope is flattened by first cutting or filling the slope, and then a plurality of vertical frames of the same length are installed at regular intervals. After that, the solar modules were sequentially coupled to the upper part of each vertical frame.

However, such a conventional technology inevitably causes problems such as environmental destruction due to cutting or filling work on slopes, and an increase in working time and cost, and in the case of rainy season due to the loss of soil on the ground, the collapse of the solar power plant is concerned. There was a problem to become.

In the present invention, the long length of the telephone poles 100 are gradually combined along the enlarged inclined surface of FIG. 1 at a predetermined interval, and then the fixing brackets 200 to be described later are combined at the same height on each of the telephone poles, so that the solar module is It can be combined in parallel with any horizontal plane, and through this, it is possible to protect the environment by omitting the cutting or filling operation of the slope 10, and to prevent the collapse of the solar power generation device by preventing the loss of soil and sand on the ground surface. It can be done, and by omitting the cutting or filling operation, the time, cost and manpower required for the overall construction work can be significantly reduced.

In addition, by using the telephone pole 100 formed in a predetermined length (6 ~ 16m) as a supporting means for the solar module 20, the solar module is sufficiently separated from the ground, so that sunlight can be sufficiently irradiated to the ground, For example, when constructing on farmland, crops can be produced on lower sites and electricity can be produced on higher sites, thus providing excellent profit-generating effects.

Next, FIGS. 3 to 4 are exemplary views of the fixing bracket 200 according to the present invention. In FIG. 3, the fitting ring is omitted to aid understanding of the body 210 and the bent part 220.

"자 형상으로 이루어진다. The fixing bracket 200 is coupled to each of the telephone poles 100 and supports the module support frame 300 that is in close contact with the rear surface of the solar module 20, and includes a plate-shaped body 210 and an upper end of the body and The bent portion 220 that is bent vertically from the lower edge is integrally formed so that when viewed from the side, approximately "

"It is made in a shape.

A "∩"-shaped fitting ring 221 into which the module support frame is inserted and fixed is formed at the upper end of the fixing bracket, that is, the upper bent part 220, and at the center of the bent part, the outer circumferential surface of the telephone pole is easily adhered to The concave portion 222 is formed to be concave inwardly so that it can be formed.

The fitting rings 221 may be respectively formed on both sides of the concave portion 222.

In addition, a reinforcing rib 212 for reinforcing strength is formed on the inner circumferential surface of the body 210, and a friction prevention pad 223 for preventing abrasion due to friction with the telephone pole is formed on the inner circumferential surface of the concave portion 222. It is equipped.

The reinforcing rib 212 may be formed at a position corresponding to the concave portion, may be formed in a plurality of upper and lower stages, and formed in a predetermined thickness to reinforce strength.

The anti-friction pad 223 may be formed of a material such as rubber, soft PVC, or silicone.

In addition, a bolt hole 211 is formed in the body 210 so that the pair of fixing brackets form a pair so that they are in close contact with each other so as to surround one and the other outer circumferential surfaces of the telephone pole and then bolted. The bolt hole 211 may be formed in plural so as to secure a fastening force.

In addition, a stopper piece 230 in close contact with the module support frame 300 may be formed on the upper end of the fixing bracket.

Referring to FIG. 2, the stopper piece 230 is formed in a trapezoidal shape having a predetermined thickness, but one edge 231 is formed in an arc shape, so that the stopper piece 230 is in close contact in a form surrounding the outer circumferential surface of the module support frame. The stopper piece 230 is formed of a predetermined thickness so as to prevent wear due to vibration and friction of the module support frame 300 and is formed of a material having excellent strength.

It is preferable that the stopper pieces 230 are provided in a pair so as to be in close contact with both sides of the lower half circumferential surface with respect to the center of the module support frame 300.

If the stopper piece 230 is not formed, since a gap is formed between the lower outer circumferential surface of the module support frame 300 and the fitting ring 221, the module support frame 300 is arbitrarily rotated inside the fitting ring 221 Shaking may occur in the vertical direction inside the fitting ring by external force such as strong wind.

Meanwhile, reference numeral 224 of FIG. 3 shows a bolt hole for bolting the fitting ring 221 and the stopper piece 230, and the fitting ring and the stopper piece are welded or bolted to the bent portion. Can be fixed.

The fixing bracket 200 configured as described above is coupled to one or more on the telephone pole, but is disposed at the same height on the opposite telephone pole, for example, the first telegraph pole 100 of 6 m on the inclined surface of FIG. 1, After installing the 8m second telegraph pole (100′) and the 14m third telegraph pole (100″) at a predetermined distance, the first telegraph pole (100) and the second telegraph pole (100″) have the same height. 1 After the fixing bracket 200 is coupled, the first solar module 20 is coupled through a module support frame and a truss structure to be described later.

Next, attach the second fixing bracket 200 ′ to the lower one side of the second telegraph pole 100 ′, and then attach the second fixing bracket 200 ′ at the same height to the third telescopic pole 100 ′, and then support the module. The second solar module 20 ′ is coupled through the frame and the truss structure.

When such a construction process is sequentially repeated, a plurality of solar modules 20 may be arranged and installed in parallel with each other with a height difference. In the present invention, through the configuration in which the fixing bracket 200 is bolted to the telephone pole 100, the height of the fixing bracket can be quickly adjusted according to the field situation, so that the solar module can be quickly combined without being affected by the slope. There is an advantage of excellent workability.

Next, the module support frame 300 is a round bar inserted to connect each of a pair of fitting rings 221 facing each other on a pair of bolted fixing brackets 200, It adheres to the back and supports the solar module.

In addition, the module support frame 300 is made of a polycarbonate material having excellent light weight and strength so that transport and construction are easy and durability can be secured.

In addition, in the module support frame 300, a strand fixing bracket 310 in a form surrounding the lower outer circumferential surface is coupled at regular intervals, and the strand 500 to which a tensile force is applied is coupled to the strand fixing bracket 310 to support the module. It is arranged along the longitudinal direction at the bottom of the frame.

For example, in a solar power generation device in which both ends of the solar module are fixed to a telephone pole and a fixing bracket, a bending moment is generated in which the central part of the solar module is bent, and one end is fixed to the telephone pole and the fixing bracket. In the photovoltaic power generation apparatus of, a bending moment at which the other end is bent is generated, and when a prestress corresponding to the generated bending moment is introduced into the module support frame, the bending moment at which the center or end of the solar module is bent can be effectively canceled.

In addition, the strands are pulled to both sides and fixed to the strands fixing bracket in a state where they are pre-stressed, so that the strands are fixed in a stressed state and pre-stress is applied to the module support frame, thereby making the bending moment easier. You can make it offset.

Through this, strength and warpage prevention are improved due to pre-stress applied in advance, and since logging, cutting, and filling of sub-sites can be omitted, environmental damage is remarkably small. In addition, since the existing land is used, there is no loss of soil, so stable operation is possible.

In addition, since there is a distance between the lower site and the module, natural cooling is easy as the inflow of wind increases, and the efficiency of the module is improved. Because of this, it has the advantage of excellent usability.

In addition, the module support frame 300 may be formed in a predetermined length, and a flange 320 having a bolt hole formed at an end thereof may be formed to extend the length according to the field situation to enable continuous fastening.

Next, the truss structure 400 is a structure that connects the photovoltaic module 20 and the module support frame 300 to stably fix the photovoltaic module 20 on the telephone pole 100, and the support frame fixing piece 410, a pair of first support frames 420 coupled to the support frame fixing piece in a "V" shape and fixed to the upper and lower surfaces of the solar module, and one end of the support frame The second support frame 430 coupled to the fixing piece is coupled between the pair of first support frames and the other end is fixed to the outer circumferential surface of the module support frame 300.

The truss structure 400 is for securing rigidity, and may be provided in plural along the length direction of the module support frame 300 in consideration of the size or area of the solar module 20, and The support frame fixing piece and the support frame fixing piece of the other truss structure may be coupled through the connection frame 440.

A fastening piece 421 having a bolt hole may be formed at an end of the first support frame 420 to facilitate coupling with the solar module. The fastening piece 421 may be integrally formed with the first support frame 420 or may be coupled through a method such as welding, and the first support frame 420 is a solar module through the fastening piece 421. It can be fixed by bolting with (20).

The end of the second support frame 430 may be fixed to the outer circumferential surface of the module support frame through welding.

In addition, the truss structure 400 may be configured to allow the angle of the solar module 20 to change according to seasonal changes. For example, when one end of the first support frame 420 is bolted to the support frame fixing piece 410, it is possible to adjust the angle formed by the pair of first support frames on the support frame fixing piece. By adjusting the angle of the photovoltaic module, it is possible to increase the light collection efficiency.

The present invention made as described above has the advantage that it is possible to omit the cutting or filling operation of the slope, and sufficiently spaced the solar module from the ground so that sunlight can be smoothly irradiated.
