[0002] Photovoltaic power stations, especially rooftop distributed photovoltaic power stations, may be threatened by lightning strikes, which can not only damage photovoltaic modules, but also cause serious damage to the entire power generation system, including inverters, distribution cabinets and other key electrical equipment.

[0003] Existing lightning protection devices for photovoltaic power stations usually fix the lightning rod in one location. It is not convenient to adjust the height of the lightning rod according to the angle differences of the surrounding photovoltaic panels so that the lightning rod is higher than the top of the photovoltaic panel to facilitate lightning attraction and grounding. Moreover, the lightning rod may tilt and shift in severe weather, affecting its lightning protection effect. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that the height of the lightning rod is not conveniently adjusted due to fixed installation; the lightning rod may be tilted and deviated, thus affecting its lightning protection effect.

[0008] Furthermore, the other end of the worm is rotated to penetrate the mounting tube and is connected to the end with a driving handle, and the worm is easily driven by the setting of the driving handle.

[0009] Furthermore, slide grooves are respectively connected to both sides of the lightning rod, and a slider slidably matched with the slide grooves is relatively connected to the installation tube. The lightning rod is slidably connected to the installation tube through the sliding cooperation between the slide grooves and the sliders.

[0010] Furthermore, the base is circumferentially connected with a plurality of reinforcing rods, which are arranged obliquely and connected to the mounting tube at the other end. The supporting strength of the mounting tube is enhanced by the coordinated arrangement of the reinforcing rods.

[0011] Furthermore, there are no less than three reinforcing rods which are evenly arranged in an array on the mounting tube, so as to stably maintain the mounting tube in a vertical state.

[0012] Furthermore, the top of the lightning rod is a conical structure, which is convenient for attracting lightning.

[0013] 3. Beneficial Effects

[0014] The advantages of the utility model compared with the prior art are:

[0015] The coordinated arrangement of the base, the lightning rod, the mounting tube, the lifting assembly, the driving rod, the worm, the worm wheel and the threaded groove makes it convenient to drive the threaded rod to rotate through the coordination of the worm and the worm wheel. Due to the sliding coordination of the lightning rod and the mounting tube, the lightning rod is driven up and down, so that the height of the lightning rod can be adjusted according to needs. At the same time, due to the sliding coordination of the lightning rod and the mounting tube, it is convenient to guide the lightning rod to avoid tilting and deviation of the lightning rod.

The top of the lightning rod 2 passes through the mounting tube 3, and a lifting component that can drive the lightning rod 2 to rise and fall is connected in the mounting tube 3. The lifting component comprises a driving rod 4 rotatably connected to the base 1, a worm 5 is rotatably connected in the mounting tube 3, and the other end of the worm 5 rotates through the mounting tube 3 and is connected to a driving handle 8 at the end, and a worm wheel 6 is connected to the outside of the driving rod 4, and the worm wheel 6 cooperates with the worm 5.
