Background technique

Photovoltaic modules are composed of solar cells or a combination of solar cells of different specifications cut by a laser machine. The current and voltage of a single solar cell are very small, and multiple solar cells can be connected in series to obtain high voltage. Multiple solar cells are packaged on a stainless steel metal shell to form a photovoltaic module, that is, a solar cell module. Photovoltaic power generation market has broad prospects. More and more public facilities and factories are beginning to use photovoltaic modules. The fixation of photovoltaic modules is also a problem today. Now photovoltaic modules are generally installed on color steel tiles or roof beams. The existing fixed The fixture is fixedly clamped on the aluminum frame of the photovoltaic module and clamped by screws, and the bottom of the fixture is installed on the beam. During the installation process, when the screw is tightened downward, the clamping mouth of the clamp is prone to warp, which causes the problem that the component falls off. Therefore, there is an urgent need to develop a photovoltaic module fixing device that is safe, reliable and not easy to fall off.

Utility model content

The purpose of the utility model is to provide a photovoltaic module fixing device, which can adjust the clamping force of the photovoltaic module, and during the adjustment process, the photovoltaic module can maintain the fixed support of the photovoltaic module, and is not easy to fall off.

For this purpose, the utility model adopts the following technical solutions:

A photovoltaic module fixing device, including a pressing block, a fastener and a beam, the pressing block is provided with a pressing part pressed on the frame of the photovoltaic module, and the pressing part extends horizontally and is provided with a direction at the extension end Downslope ends.

In a further technical solution, the pressing block has an inverted U-shaped cross-section, including a top wall, an outer side wall away from the frame of the photovoltaic module, an inner side wall adjacent to the frame of the photovoltaic module, and the pressing part extending horizontally from the inner side wall. The wall is directly pressed against the beam, and there is a pressing gap between the bottom of the inner wall and the beam.

In a further technical solution, the pressing part is provided with a serrated surface or a corrugated surface in contact with the frame.

In a further technical solution, the fixing device further includes an inner liner, the inner liner is located between the pressure block and the beam and is connected to the beam, and the inner liner is connected to the pressure block through a fastener.

In a further technical solution, the fastener is a screw, and the screw is screwed into the inner liner through the pressing block.

In a further technical solution, the contact surface between the beam and the frame of the photovoltaic module is a serrated or corrugated surface.

The beneficial effects of the utility model:

In the photovoltaic module fixing device provided by the utility model, the pressing part of the pressing block has a downwardly inclined end at the end far away from the pressing block, and the frame can be clamped by using the downwardly inclined end, and when the clamping force is adjusted, the It will not fall off due to warping, thereby overcoming the problem that the fixing device is easy to fall off in the prior art.

Detailed ways

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

Fig. 1 is an assembly diagram of a photovoltaic module and a fixing device provided by a specific embodiment of the present invention. As shown in Figure 1, the photovoltaic module fixing device includes a pressing block 1, a fastener 2 and a beam 3, and Figure 3 is a schematic structural diagram of the pressing block 1, and the pressing block 1 is provided with a pressing block pressed on the frame 7 of the photovoltaic module 4 part 5, the pressing part 5 extends horizontally and is provided with a downwardly inclined end at the end of the extension, the pressing block 1 has an inverted U-shaped cross-section, including a top wall 9 and an outer side away from the frame 7 of the photovoltaic module 4 The wall 10, the inner wall 11 adjacent to the frame 7 of the photovoltaic module 4, and the pressing part 5 extending horizontally from the inner wall 11, the outer wall 10 is directly pressed against the beam 3, and the bottom of the inner wall 11 is in contact with the There is a pressing gap between the beams 3. As shown in FIG. 2, the downwardly inclined end of the pressing part 5 clamps the frame 8 to prevent the fixing device from falling off. The pressing part 5 and the frame 8 of the photovoltaic module 4 The contact surface is a serrated surface or a corrugated surface, which is used to increase the friction between the pressing part 5 and the frame 8, and further prevent falling off.

The fixing device also includes an inner lining board 6, the inner lining board 6 is located between the pressure block 1 and the crossbeam 3 and connected with the crossbeam 3, the inner lining board 6 and the crossbeam 3 are clamped, and can also be selected In other connection methods, the inner lining board 6 is connected to the pressing block 1 through a fastener 2, the fastener 2 is preferably a screw, and the screw is screwed into the inner lining board 6 through the screw hole 8 on the pressing block 1 ,as shown in picture 2.
