As shown, when the photovoltaic power generation system according to an embodiment of the present invention is an aquatic photovoltaic power generation system installed on the water, a plurality of solar panel 30 as well as a combination of profile assembly 20 and float 10 Dozens of unit units are arranged in a checkerboard form to the left and right over a large area to form a set (in the case of FIG. 1, A, A1, B, B1 type unit units are arranged), each The unit units are connected to each other by an elastic bracket 100 for connection as shown in FIGS. 2 to 4.

In the construction of the above-described photovoltaic power generation system, in the case of the algae repellent 200, it is simply installed on the solar panel 30 and is configured to effectively block algae from sitting. (In this embodiment, for convenience, the algae eradication 200 is described as being applied to and used in a photovoltaic power generation system, but of course, the same can be applied to a photovoltaic power generation system installed on the ground.)

Hereinafter, a solar power generation system according to an embodiment of the present invention will be described in more detail with reference to the algae repellent 200.

5 and 6 are perspective views of algae repelling in a photovoltaic power generation system according to an embodiment of the present invention, FIG. 7 is a side view of algae repelling in a photovoltaic power generation system according to an embodiment of the present invention, and FIG. In the solar power system according to an embodiment of the present invention is a reference diagram showing the connection state between the wire support member and the wire of the algae eradication, Figure 9 is a wire of algae eradication in the solar power system according to an embodiment of the present invention Side view with the support member, Figure 10 is a plan view of the wire support member of the algae repellent in the photovoltaic power generation system according to an embodiment of the present invention, Figure 11 is a bird in the photovoltaic power generation system according to an embodiment of the present invention It is a cross-sectional view of the frame fixing member of the repeller.

As shown, the algae repellent 200 is supported by the wire support member 210 and the frame fixing member 220 and the wire support member 210 which are installed on the left side of the solar panel 30 and the upper edge of the post. It is made of a wire 230 that blocks algae from sitting while forming a parallel line along the upper side of the upper line of the solar panel 30. Hereinafter, the algae repellent 200 will be described in more detail with respect to each of the above components.

First, the wire support member 210 includes a side contact portion 212 formed in an orthogonal shape to closely fit along the side of the upper edge frame of the solar panel 30 and the lower surface of the upper edge frame of the solar panel 30. Accordingly, when formed in an orthogonal shape to be closely padded, it is formed of a contact portion 211 and an upper extension portion 213 formed to extend upward from the side contact portion 212 to support the wire 230.

Here, the upper extension portion 213 of the wire support member 210 extends upwardly from a central portion orthogonally bent at the lower contact portion 211 and is formed in a column shape of an orthogonally bent L-shaped cross section, in each direction. A pair of wire balls 213a are formed. The wire hole 213a is made to pass through the wire 230 and is formed in pairs on the upper and lower portions as shown in FIG. 8 to make one wire 230 into two lines parallel from the upper side and the lower side. Be supportive. Thus, if one wire 230 is made of two parallel lines, even if one of the lines is disconnected, the remaining one line may remain and prevent the bird from invading until repaired by the manager.

The frame fixing member 220 is formed with a hook portion 222, one end of which is bent in a U shape and padded with each other, together with the bottom edge portion of the solar panel and the bottom contact portion 211 of the wire support member 210. It consists of a lower surface support portion 221 and a side support portion 223 extending upwardly from the other end of the lower surface support portion 221 to be supported on the side surface of the upper edge frame of the solar panel.

Here, it can be noted that the frame fixing member 220 is made of an initial angle of 70 to 85 degrees as shown in FIG. 11 in a state in which an external force is not applied to the lower surface support portion 221 and the side support portion 223. According to this configuration, when the frame fixing member 220 is installed on the solar panel, the support bolt 224 provided in a state passing through the side support 223 as shown in FIG. 7 has a side contact portion of the wire support member 210 With 212 interposed therebetween, it is possible to impart tension while spreading the side support portion 223 while being supported by the side portion of the upper edge frame of the solar panel. Then, as shown in FIG. 5, the wire support member 210 and the frame fixing member 220 are firmly supported by the solar panel 30 by the tension action of the side support 223. (However, the state before applying tension to the frame fixing member 220 is shown in Fig. 6. In this state, the tension is applied to the frame fixing member 220 by the support bolt 224 to make it robust, if If installed without tension, as shown in Figure 6, the frame fixing member 220 as well as the wire support member 210 are easily separated from the solar panel 30 and fall off.)

As described above, points to be noted in the configuration of the wire support member 210 and the frame fixing member 220 that are respectively installed on the left side of the solar panel 30 and the upper edge of the post and serve to support the wire 230 are the solar panel ( 30) It is that a sturdy installation is possible without any damage to the frame by drilling or welding to install the fastening parts, and it can be installed regardless of the frame width of the solar panel 930).

The wire 230 is installed in parallel with two rows spaced apart from the upper side of the solar panel as shown in the drawing. To this end, starting with the support bolts 224 of the frame fixing member 220 installed on the upper edge of one piece of the solar panel 30, the wire support member 210 installed on the left side and the post of the solar panel 30 The wire 230 may be installed by way of passing through the wire hole 213a. When four wire holes 213a are formed per wire support member 210 installed on the left side and the post of the solar panel 30, the wires 230 are sequentially penetrated through the wire holes 213a in various ways. Here's how to explain one of them:

That is, starting from the support bolt 224 of the frame fixing member 220 installed on the upper edge of the post of the solar panel 30, the wire is connected to the wire hole 213a of the pair of wire support members 210 coupled to the lower side. After passing through the wire hole 213a, it is dragged to the left side on the opposite side of the solar panel 30. Thus, the first line is formed by the wire 230. Subsequently, the wire 230 is sequentially passed through the lower wire hole 213a and the upper wire hole 213a among the pair of wire holes 213a of the wire support member 210 installed at the upper left corner, and then back to the solar panel. Of the pair of wire holes 213a of the wire support member 210 installed on the upper edge of the postal edge of 30, the wire wires 213a of the upper side are dragged and passed through. As a result, a second line spaced parallel to the upper side with respect to the first line formed by the wire 230 is formed. The end of the wire via the upper wire hole 213a is knotted and finished in a state supported by the support bolt 224.

Here, when passing through the wire support member 210 installed on the left side of the wire 230, it is preferable to make an intermediate knot on the support bolt 224 without simply passing through the wire hole 213a. This is because even if one of the two lines by the wire 230 is broken, the other remains and the function of blocking algae can be continued.

On the other hand, in the photovoltaic power generation system according to an embodiment of the present invention, the connecting elastic bracket 100 is provided to actively accommodate the relative vertical and horizontal displacements, horizontal displacements, and rotational displacements between the unit units while connecting the unit units. In addition, the elastic bracket 100 provided in this way greatly improves durability by alleviating, absorbing, and blocking the shock transmitted between unit units, thereby reducing the accumulated fatigue load, and thus, without frequent replacement or maintenance of the profile assembly 20. It is designed to be used for a long period of time over a year.

Hereinafter, a photovoltaic power generation system according to an embodiment of the present invention will be described in more detail with reference to the connecting elastic bracket 100. The connecting elastic bracket 100 is not necessary in the photovoltaic system installed on the ground, but is a very important component in the water photovoltaic system installed on the water surface.

12 is a perspective view of an elastic bracket for connection in a solar power system according to an embodiment of the present invention, FIG. 13 is an exploded perspective view of an elastic bracket for connection in a solar power system according to an embodiment of the present invention, and FIG. 14 is It is a front view of the elastic bracket for connection in the solar power system according to an embodiment of the present invention, and FIG. 15 is a plan view of the elastic bracket for connection in a solar power system according to the embodiment of the present invention. And Figure 16 is a cross-sectional view of the elastic bracket for connection in the solar power system according to an embodiment of the present invention.

As shown, the connecting elastic bracket 100 is one side profile belonging to the profile assembly 20 of one unit unit and the profile assembly 20 of the other unit unit, which are adjacent to each other on one side and the other side in the photovoltaic system. (21) serves to connect the other side profile (21) in the longitudinal direction.

To this end, the elastic bracket 100 for connection includes a pair of coupling members 110 provided at a distance from each other, a guide pin 120, a coil spring 130, and a pair of low friction members 140 Is done by

The coupling member 110 is a U-shaped member that is coupled to the end of the profile at each position, and a pair of horizontal portions 112 spaced apart from the upper and lower sides so as to be coupled in contact with the upper and lower ends of the profile. ), a vertical connecting portion 111 vertically connecting the pair of horizontal portions 112. Here, the horizontal portion 112 is provided with a bolt hole 112a so that a bolt supporting the upper and lower ends of the profile can penetrate. Here, the bolt hole 112a is preferably spaced apart from each other to form a pair. As a result, when bolts are installed on both of the two bolt holes 112a, the coupling member 110 cannot be rotated with respect to the profile end, and when only one of the two bolt holes is installed, the coupling member against the profile end 110 is in a rotatable state. Therefore, one of the two paired coupling members 110 may be installed so that only one of the two bolt holes 112a is installed so that the horizontal rotation between the profile and the coupling member 110 is possible.

The guide pin 120 is installed between the coupling member 110 located on one side and the coupling member 110 located on the other side, with one end and the other end penetrating through the through hole 111a of the coupling member 110, respectively. do. At this time, the head portion 120a having a diameter larger than the body is formed at one end of the guide pin 120, and the nut 150 is fastened or a release prevention pin is installed at the other end as shown in the drawing to guide pin 120 Each end of the is prevented from separating from the coupling member 110. In the case of the guide pin 120, since both ends are installed through the coupling member 110, a free rolling operation between the coupling members 110 is possible, and the coupling member 110 through which the guide pin 120 penetrates is possible. Because it is thin, it is allowed to bend.

According to the configuration in which the guide pin 120 is installed through the coupling member 110 located on both sides, the coil spring 130 is protected from being twisted or deviated when the coil spring 130 is compressed. As a result, it is possible to solve the problem that the coil spring 130 does not perform the buffer function in a state in which the coupling member 110 is detached or excessively twisted.

The coil spring 130 is installed in a form surrounding the outer side of the guide pin 120 between the coupling member 110 located on one side and the coupling member 110 located on the other side. Here, both ends of the coil spring 130 are not directly coupled to the coupling member 110, but are inserted into the insertion groove 140a of the low friction member 140 intervening in the middle, and the guide pin 120 is the central axis. And freely rotate (rolling direction). When such a coil spring 130 is installed, it is possible to significantly improve durability by reducing, absorbing, and blocking shock transmitted between unit units in the middle to reduce the fatigue load accumulated in the profile assembly of the unit unit.

The low friction member 140 is interposed between the one end of the coil spring 130 and the coupling member 110 on one side, and between the other end of the coil spring 130 and the coupling member 110 on the other side, the coil spring ( 130) and the coupling member 110 serves to effectively prevent the occurrence of severe friction damage and noise. To this end, the low friction member 140 is made of a polypropylene material that has low friction characteristics and is inexpensive. In addition, the low friction member 140 has a through hole in the center and is made of a flat cylindrical body fitted into the guide pin 120, but includes an insertion groove 140a into which the end of the coil spring 130 is inserted.

When the low friction member 140 is provided as described above, when the coupling member 110 is rolled around the guide pin 120, the low friction member 140 located in the middle is the coupling member 110 and the low friction member 140. It prevents damage and noise caused by liver surface friction. In addition, if the low friction member 140 and the guide pin 120 are not directly connected between the coil spring 130 and the coupling member 110, the relative tilting operation between the coil spring 130 and the coupling member 110 is In the rolling operation, damage due to friction is inevitable and generation of crackling noise is unavoidable. In the case of the present invention, such a problem does not appear.

Although the preferred embodiments of the present invention have been described above, the present invention can use various changes, modifications, and equivalents. It is clear that the present invention can be equally applied by appropriately modifying the above embodiments. Accordingly, the above description is not intended to limit the scope of the present invention as defined by the following claims.
