To improve the use stability of photovoltaic distribution boxes, corresponding lightning protection structures can be set to reduce the risk of damage.

[0003] Prior Art 1 (a Chinese patent with the publication number CN110445032A, published on November 12, 2019): A waterproof and lightning protection distribution box, including a lightning protection box, a waterproof box, a moisture-proof mechanism, and a lightning protection mechanism. The waterproof box is installed inside the lightning protection box. The waterproof box is provided with a sealing door, and the sealing door is hinged to the waterproof box. The moisture-proof mechanism is arranged on the outer side of the waterproof box body, and the lightning protection mechanism is installed on the lightning protection box. This technology is provided with a waterproof box and a lightning protection box. Through the setting of the lightning protection box, lightning is guided to the ground to prevent the waterproof box from being damaged by lightning strikes. When a small amount of accumulated water flows into the lightning protection box, through the setting of the waterproof box, the accumulated water and the humid air inside the lightning protection box can be blocked to prevent moisture from entering the waterproof box and damaging the electrical components inside the waterproof box. When repairing the waterproof box, the waterproof box can be pulled out of the lightning protection box, facilitating the maintenance work of the waterproof and lightning protection distribution box by maintenance personnel; Prior Art 2 (a Chinese patent with the publication number CN114976929A, published on August 30, 2022): A distribution box for a photovoltaic microgrid, including: a distribution box body, a wiring seat, a self-locking joint assembly, and a floating socket. The wiring seat is fixedly installed inside the distribution box body, and a wiring terminal row is fixedly installed on the surface. A plurality of plug-in ends are provided on the surface of the wiring terminal row. The self-locking joint assembly is detachably connected to the wiring seat. The floating socket includes a fixed seat, a mounting hanging plate, and a damping guide rod. The two ends of the damping guide rod are respectively movably connected to the surfaces of the fixed seat and the mounting hanging plate. One side of the mounting hanging plate is fixedly connected to the surface of the distribution box body. This technology improves the joint strength by setting a new wiring connection structure and using the locking engagement between the locking member on the surface of the joint body and the plug-in end. After the joint connection is inserted, the moving locking rod is ejected by rotating the joint body to lock with the inner side of the plug-in end.

After the plug connector disconnects the circuit connection of the box body, the reset of the buffer plate can automatically trigger the sealing plate to block the heat dissipation slots, achieving a flame retardant effect on the inside of the box body.

[0020] By setting the lightning rod, the device can achieve a lightning protection effect, and the telescopic protection tube outside the lightning rod can protect it when the lightning rod is not in use, reducing the pollution it receives, and at the same time, it can also reduce the oxidation of the lightning rod caused by the external environment, ensuring its lightning protection effect.

A lightning protection mechanism is provided above the box body 1 to provide lightning protection for the box body 1. A transmission line 12 is arranged inside the box body 1, and a disconnection control mechanism is arranged below the transmission line 12 to control the disconnection of the circuit inside the box body 1. A positioning groove 16 is formed on the side of the box body 1, and a buffer plate 14 is engaged inside the positioning groove 16. Moreover, a heat dissipation groove 15 is formed below the buffer plate 14. A movable plate 17 is arranged on the right side of the buffer plate 14. A vertical sliding structure is formed between the movable plate 17 and the buffer plate 14. Moreover, a second spring 18 is fixed above the movable plate 17 to provide a downward thrust for the movable plate 17, so that the movable plate 17 blocks the heat dissipation groove 15. A blocking mechanism is arranged on the outside of the movable plate 17 to provide a limiting effect for the movable plate 17. The right side of the buffer plate 14 is connected with an inner pulling mechanism, and the inner pulling mechanism is connected with the disconnection control mechanism. After the buffer plate 14 moves outward, the connection of the transmission line 12 is automatically disconnected. The buffer plate 14 and the transmission line 12 are symmetrically arranged about the left and right of the box body 1. Moreover, a series connection line 13 is connected below the disconnection control mechanisms below the two groups of transmission lines 12 to connect the circuits in series. A handle 1701 is fixed inside the movable plate 17 to control the upward movement of the movable plate 17. Moreover, a sealing and fitting mechanism is arranged in the middle of the movable plate 17. The sealing and fitting mechanism includes a sealing plate 19, a first magnet 20 and a second magnet 21.

At the same time, the cleaning block 5 can also play a cleaning role to avoid phenomena such as oxidation, rust or dust accumulation due to the long-term exposure of the lightning rod 3. When it is needed, control the connecting ring 4 to move downward to expose the lightning rod 3.
