Description

[0001] The present invention relates to a frame for installing a solar module and a solar module using the same,

The present invention relates to a frame for transmitting a load of a solar module to a structure, and more particularly, to a solar module frame capable of immersing and flaming in a marine environment and capable of freely mounting and fixing a solar module frame The present invention relates to a frame, a joining member, and a solar module installation structure using the same.

The solar module frame serves to protect the tempered glass that protects the solar cell. The load applied to the solar module is transmitted to the structure (or structural member) through the solar module frame.

Generally, the solar module frame uses a lightweight aluminum material. In the case of a photovoltaic module frame made of aluminum, there is a problem that it is vulnerable to a marine installation in which wet and salt environments must be taken into consideration.

On the other hand, when the solar module frame is mounted on the structure, the assembling workability should be considered. For example, when the solar module 10 is installed as shown in FIG. 8, a lower end surface of the frame 2 is required to have a length L of at least a certain length for installing the bolts B in the structure 1, It is also necessary to secure a certain length. In this case, since the nut (N) needs to be fastened at the rear part of the solar module, it becomes very difficult to construct.

As a background of the present invention, a frame structure of a conventional photovoltaic module will be described. As shown in Korean Registered Utility Model No. 20-0417566, a photovoltaic module for holding and fixing a photovoltaic module for converting solar energy into electric energy Wherein a wedge coupling groove is formed in an inner wall surface of the module to fit the wedge member and the wedge coupling groove is formed at an upper side or a lower side of the wedge coupling groove, A frame member having a protruding jaw portion for stowing the photovoltaic module between the frame member and the member; And a wedge member for fixing the photovoltaic module to the frame member by staking the photovoltaic module therebetween so that a part of the exposed portion thereof corresponds to the jaw portion, And is characterized by comprising:

However, the background art has a structure in which the flange is located on the inside of the frame member (below the solar module) and is fastened with a bolt. Therefore, tightening the bolt and nut not only disturbs the PV module panel, but also narrows the working space. Therefore, there is a problem that it is very difficult to construct the solar module because the solar module is installed at the rear part of the solar module.

At this time, the four frames 12 are assembled with the corner keys 30 as shown in Fig. 2 at the corner portions. The frames (12, 12a, 12b, 12c) applied to the present invention are made of carbon fiber reinforced plastics which are superior in light weight, strength and rigidity to aluminum in pearl truing method. This is because when each frame is installed in the ocean, it has resistance to weather and salt, which can overcome the marine environment.

The present invention can be implemented in various forms according to the sectional structure of the frames 12, 12a, 12b, and 12c, the connection structure between the frames, and the like.

≪ Embodiment 1 >

3, the frame 12 includes a module coupling portion 121 having a module coupling groove 121a opened toward the rim of the solar cell module 10 along the longitudinal direction, And a frame leg 123 extending vertically downward from one side of the bottom surface of the hollow support portion 122. The frame leg 123 An outer joint flange 124 which is horizontally bent at a lower end of the outer joint flange 124 and extends a predetermined length in the outer direction of the frame and a joint joining jaw 125 which forms a joining member fitting groove at the end of the outer joint flange 124.

The frame 12 having such a sectional structure allows the solar module to be completely installed through the connection structure with the solar module frame joining member 20 connecting the outer joint flanges 124 to each other.

The solar module frame joining member 20 is shown in Figs. 3 and 4. Fig. 4, the solar module frame joining member 20 includes an elastic pressing portion 21 having at least one bolt fastening hole 21a at the center thereof, And joint engaging portions 22 and 22 for forming an engaging groove 22a. At this time, the elastic pressing portion 21 has a predetermined radius of curvature R so as to form a convex curved surface upward.

The elastic pressing portion 21 may be flat on its upper surface (the surface on which the bolt fastening hole 21a is located) to have a flat surface. The length of the solar module frame joining member 20 is shorter than the length of the unit frame 12. Accordingly, one or more solar module frame joining members 20 are installed in a row.

Therefore, the fixing operation between the frames 12 and 12 arranged adjacent to the upper surface of the structure 1 through the solar module frame joining member 20 as shown in FIG. 3 can be performed from the front side.

That is, as shown in FIG. 3, frames 12 and 12 are disposed adjacent to each other with equal spacing on both sides with respect to a fastening hole 1a formed on the upper surface of the structure 1, and a solar module frame joining member 20 Of the frame 12 to the joint joining jaw 125 of each of the frames 12, 12. And then the bolts 50 are inserted into the bolt fastening holes 21a and the structure fastening holes 1a and then the nuts 51 are fastened to the bolts 50. [ At this time, the bolt (50) and the nut (51) are fastened to each other at the front surface of the adjacent frames (12, 12).

Particularly, the resilient pressing force of the elastic pressing portion 21 is increased according to the fastening force of the bolt 50, so that the solar module frame joining member 20 can securely fix the frames 12 and 12 to the structure 1 more strongly .

At this time, the neighboring frames 12 and 12 are coupled to the joint joining portion 22 of the solar module frame joining member 20 so that the positional change of the fixed posture is prevented.

Also, the fastening force of the bolt 50 is maintained by the resilient restoring force of the elastic pressing portion 21 to prevent loosening.

≪ Embodiment 2 >

The sectional structure of the frame 12a according to the second embodiment is shown in Fig. 5, the frame 12a includes a module coupling portion 121 having a module coupling groove 121a opened toward a rim portion of the solar module 10, a hollow portion 122a of the hollow support portion 122 and a hollow support portion 122 for supporting the module connection portion 121 at the lower portion and a hollow support portion 122 for supporting the module connection portion 121 in the outward direction A vertical engagement protrusion 125a protruding vertically upward from the distal end of the outer joint flange 124a and one or more shear key engagement holes 124a penetrating vertically to the outer joint flange 124a, (128). In the present embodiment, the shear-key engagement hole 128 is formed as a square hole, but the present invention is not limited thereto.

The frame 12a having such a sectional structure allows the solar module to be completely installed through the connection structure with the solar module frame joining member 20a that connects the outer joint flanges 124a to each other.

A solar module frame joining member 20a is shown in Figs. 5 and 6. Fig.

5, the solar module frame joining member 20a includes an elastic pressing portion 21 having at least one bolt fastening hole 21a at the center thereof and a pair of elastic pressing portions 21a and 21b for joining the frame to both ends of the elastic pressing portion 21. [ And one or more shear keys 23 projecting downward from the lower surface of the frame engaging portions 22 and 22 to be engaged with the shear key engaging holes 128 ).

At this time, the bottom surface of the elastic pressing portion 21 is positioned above the bottom surface of the frame 12a and has a lifting clearance P. The length of the solar module frame joining member 20a is shorter than the length of the unit frame 12a. Accordingly, one or more solar module frame joining members 20a are installed in a row.

Therefore, the fixing operation between the frames 12a and 12a disposed adjacent to the upper surface of the structure 1 through the solar module frame joining member 20a as shown in FIG. 5 can be performed from the front side.

5, the frames 12a and 12a are arranged on the upper surface of the structure 1 so as to be adjacent to each other with equal spacing on both sides with respect to the fastening holes 1a formed in the structure 1, The joint joining portions 22 of the frame joining member 20a are engaged with the vertical joining jaws 125a of the frames 12 and 12, respectively. At this time, the shear key 23 of the solar module frame joining member 20a is inserted into the shear-key joining hole 128 and is engaged.

And then the bolts 50 are inserted into the bolt fastening holes 21a and the structure fastening holes 1a and then the nuts 51 are fastened to the bolts 50. [ At this time, the bolt (50) and the nut (51) are fastened to each other at the front surface of the adjacent frames (12, 12).

Particularly, the resilient pressing force of the elastic pressing part 21 which receives the pressing force according to the fastening force of the bolt 50 increases the elastic repulsive force. As a result, the solar module frame joining member 20a causes the frames 12a, And more tightly fixed thereto.

At this time, in a state in which the vertical hooks 125a of the frames 12a and 12a are positioned in the joint joining portion 22 of the solar module frame joining member 20a, the shear keys 23 of the solar module frame joining member 20a, Are engaged with the shear-key engagement holes 128 of the frames 12a and 12a, respectively. Therefore, the fixed posture of the frames 12a and 12a is maintained unchanged.

Further, the resilient pressing force of the elastic pressing portion 21 prevents the bolt 50 from being loosened.

≪ Third Embodiment >

Sectional structures of the frames 12b and 12c according to the third embodiment are shown in Figs. 7A and 7B. The frames 12b and 12c are not of the same structure but are connected to each other with different shapes.

One side frame 12b includes a module coupling portion 121 having a solar module coupling groove 121a opened toward the rim of the solar cell module 10 along the longitudinal direction as shown in Figs. 7A and 7B, A hollow support portion 122 having a hollow portion 122a penetrating in the direction of the hollow support portion 122 and supporting the module coupling portion 121 at a lower portion thereof, And an outer lower joint flange 124b.

The other frame 12c includes a module coupling portion 121 having a solar module coupling groove 121a opened toward the rim of the solar cell module 10 along the longitudinal direction and a hollow portion 122a An outer upper joint flange 124c having a predetermined height from the bottom surface of the hollow support portion 122 and extending in the outer direction of the frame, ). At this time, the outer upper joint flange 124c has a predetermined curvature radius so as to have a convex curved surface upward.

As described above, the side frames 12b and 12c have the same cross-sectional structure as that of the outer lower joint flange 124b and the outer upper joint flange 124c. 7B, the outer upper joint flange 124c is positioned above the outer lower joint flange 124b so that its distal end is in contact with the upper surface of the outer lower joint flange 124b.

Therefore, unlike the first and second embodiments, the third embodiment can be installed from the front without being disturbed by the solar module without a separate joint member.

That is, as shown in FIG. 7B, the frames 12b and 12c on the opposite sides are arranged, and the outer upper joint flange 124c is positioned over the outer lower joint flange 124b. The bolts 50 are passed through bolt fastening holes (not shown) of the outer upper joint flange 124c and the outer lower joint flange 124b, and then the nuts 51 are fastened. At this time, when the fastening force of the bolt 50 and the nut 51 as the fastening means is increased, the elastic repulsive force of the outer upper joint flange 124c is increased so that the outer lower joint flange 124b is strongly pressed, 12b, and 12c.

Thus, the bolt 50 can be fastened on the front surface of the solar module, thereby improving the workability. And the bolt 50 is prevented from being loosened by the elastic repulsive force of the outer upper joint flange 124c.

According to various structures of the solar module mounting frames 12, 12a, 12b, and 12c surrounding the periphery of the solar module 10 and supported on the structure 1 as described above, the bolt 50 or the nut 51 The joining member 20 or 20a or the upper and lower joint flanges 124c and 124b can be installed on the front surface of the solar module 10 to improve the workability.

The joining member 20 or 20a firmly engages with the solar module mounting frame 12 or 12a and is firmly fixed to the structure 1 by exerting an elastic pressing force of the elastic pressing portion 21, The installation safety of the apparatus is improved.

Also, the solar module module mounting frames 12, 12a, 12b, and 12c are made of carbon fiber-reinforced plastic, easy to handle, resistant to moisture and flame resistance,
