Description

Technical Field

[0001] This utility model relates to the field of photovoltaic device technology, and in particular to a photovoltaic device with lightning protection components. Background Technology

[0002] A photovoltaic (PV) system is a system that uses solar energy to generate electricity. It mainly consists of a PV inverter, PV support structure, and PV cables. It is also equipped with supporting facilities such as lightning protection devices and detection systems. The DC current generated by the PV modules is collected by the combiner box and then enters the inverter. The inverter converts the DC current into AC current and then connects it to the low-voltage AC busbar of the power grid distribution room through the grid-connected cabinet.

[0003] Existing photovoltaic (PV) devices typically assemble their lightning protection components directly after production. However, these components may become damaged due to time or external environmental factors during subsequent use, requiring them to be sent back to the manufacturer for repair. Disassembling these components is cumbersome, and they are generally large and inconvenient to transport. Furthermore, they are easily damaged by other goods during transport. Therefore, we propose a PV device with integrated lightning protection components. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology. The existing photovoltaic device lightning protection components are generally directly assembled after production. However, the lightning protection components may be damaged due to time factors or external environment during subsequent use and need to be sent back to the manufacturer for repair. Disassembling the lightning protection components is cumbersome, and the lightning protection components are generally large in size, which is not convenient for transportation. Moreover, the components are easily damaged by the squeezing of other goods during the later transportation process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] As a preferred embodiment of this utility model, a support frame is fixed at the top of the base plate near the corner, and a photovoltaic panel is installed at the top of the support frame.

[0008] The technical effect of adopting the above-mentioned further solution is that the support frame can support the photovoltaic panel and also help to fix the photovoltaic panel.

[0009] As a preferred embodiment of this utility model, the mounting block is adapted to the mounting groove, and the first fixing bolt is adapted to the first threaded hole.

[0010] The technical effect of adopting the above-mentioned further solution is that by matching the mounting block with the mounting groove and the first fixing bolt with the first threaded hole, the mounting plate and the base plate can be installed or disassembled more conveniently.

[0011] As a preferred embodiment of this utility model, an insulating pad is adhered to the inner wall of the mounting groove, and the insulating pad is made of rubber.

[0012] The technical effect of adopting the above-mentioned further solution is that the design of the insulating pad can effectively prevent current from flowing from the mounting plate to the base plate.

[0013] As a preferred embodiment of this utility model, the lightning rod is adapted to the fixing groove, the second fixing bolt extends into the interior of the fixing groove, and the second fixing bolt is adapted to the second threaded hole.

[0014] The technical effect of adopting the above-mentioned further solution is that by matching the lightning rod with the fixing groove and the second fixing bolt with the second threaded hole, it is more convenient to install or remove the lightning rod.

[0015] As a preferred embodiment of this utility model, the lightning rod is made of stainless steel and the grounding rod is made of copper.

[0027] Example 1

[0028] like Figure 1-3As shown, this utility model provides a technical solution: a photovoltaic device with lightning protection components, including a base plate 1. A mounting groove 2 is formed on the front of the base plate 1, for mounting a mounting plate 3 and a mounting block 301. The mounting plate 3 is provided on the front of the base plate 1, and a mounting block 301 is fixed to the side of the mounting plate 3 near the mounting groove 2. The mounting block 301 can be installed inside the mounting groove 2. A first fixing bolt 302 is provided at the top of the mounting block 301 near the mounting groove 2. A first threaded hole 201 is formed on the inner wall of the mounting groove 2 corresponding to the first fixing bolt 302, allowing the first fixing bolt 302 to rotate into the first threaded hole 201. The mounting plate 3 has a fixing groove 303 at its top and near the front. A lightning rod 304 is installed at the top of the fixing groove 303 to prevent lightning from affecting the photovoltaic panel 102. A second fixing bolt 305 is installed on the front of the mounting plate 3 corresponding to the fixing groove 303. A second threaded hole 306 is installed on the bottom of the lightning rod 304 corresponding to the second fixing bolt 305. The second fixing bolt 305 and the second threaded hole 306 cooperate to fix the lightning rod 304. A grounding rod 307 is installed on the inner side wall of the fixing groove 303 and extends to the bottom of the mounting plate 3. The grounding rod 307 can conduct current to the ground.

[0029] Example 2

[0030] like Figure 1-3 As shown, a support frame 101 is fixed at the top of the base plate 1 near the corner. A photovoltaic panel 102 is installed at the top of the support frame 101. The support frame 101 can support the photovoltaic panel 102 and also help to fix the photovoltaic panel 102.

[0031] The mounting block 301 is adapted to the mounting groove 2, and the first fixing bolt 302 is adapted to the first threaded hole 201. By adapting the mounting block 301 to the mounting groove 2 and the first fixing bolt 302 to the first threaded hole 201, the mounting plate 3 and the base plate 1 can be installed or disassembled more conveniently.

[0032] An insulating pad 202 is adhered to the inner wall of the mounting groove 2. The insulating pad 202 is made of rubber. The design of the insulating pad 202 can effectively prevent current from flowing through the mounting plate 3 to the base plate 1.

[0033] The lightning rod 304 is adapted to the fixing groove 303, and the second fixing bolt 305 extends into the interior of the fixing groove 303. The second fixing bolt 305 is adapted to the second threaded hole 306. The adaptation of the lightning rod 304 to the fixing groove 303 and the adaptation of the second fixing bolt 305 to the second threaded hole 306 make it easier to install or remove the lightning rod 304.

[0034] The lightning rod 304 is made of stainless steel, while the grounding rod 307 is made of copper. The stainless steel lightning rod 304 has a more stable structure, is not easy to corrode, and has a longer service life, while the copper grounding rod 307 has a stronger conductivity and can effectively conduct current to the ground.

[0035] The working process of this utility model is as follows: When a photovoltaic device with a lightning protection component needs to be returned to the factory for repair, the worker can first loosen the first fixing bolt 302 to separate the first fixing bolt 302 from the first threaded hole 201, and remove the mounting block 301 from the inside of the mounting groove 2, so that the mounting plate 3 can be separated from the base plate 1. At this time, the worker can loosen the second fixing bolt 305 to rotate the second fixing bolt 305 and separate it from the second threaded hole 306, so that the lightning rod 304 can be disassembled. This allows the worker to package and transport each component separately. Compared with existing photovoltaic devices with lightning protection components, this method is more convenient to disassemble and greatly improves the safety of the lightning protection component during transportation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
