[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a photovoltaic surge protector, including a positioning frame 1, support legs 2, positioning bolts 3, adjusting rods 4, retaining rings 5, sleeves 6, clamping arms 7, limiting sleeves 8, surge protector body 9, clamping plates 10, limiting frames 11, limiting mechanisms 12, knobs 1201, clamping plates 1202, and anti-slip pads 1203. Support legs 2 are fixed to both the upper and lower ends of the back of the positioning frame 1, and positioning bolts 3 are installed on the support legs 2. Adjusting rods 4 are movably connected to the inner wall of the positioning frame 1, and the adjusting rods 4 inside the positioning frame 1... Both ends of the lower outer wall are fixedly provided with retaining rings 5, and the outer wall of the adjusting rod 4 on the side of the retaining ring 5 is fitted with a sleeve 6. The outer wall of the sleeve 6 is fixedly connected with a clamping arm 7. At the same time, the inner wall of the positioning frame 1 on the side of the clamping arm 7 is fixedly installed with a limiting sleeve 8. The center of the front of the positioning frame 1 is movably connected with the surge protector body 9. The upper and lower ends of the back of the surge protector body 9 are fixed with clamping plates 10. The upper and lower sides of the positioning frame 1 on both sides of the surge protector body 9 are fixedly installed with limiting frames 11. The inner wall of the limiting frame 11 is provided with a limiting mechanism 12.

[0022] The positioning frame 1 and the adjusting rod 4 are rotatably connected, and the retaining ring 5 and the sleeve 6 are in contact, which makes it easy for the user to rotate the adjusting rod 4 and to limit the sleeve 6 by the retaining ring 5 in contact with the sleeve 6.

[0023] The adjusting rod 4 and the sleeve 6 are threaded, and the direction of the thread on the outer wall of the adjusting rod 4 is symmetrically distributed about the transverse central axis of the positioning frame 1. The clamping arm 7 forms a sliding structure with the limiting sleeve 8 and the clamping plate 10 respectively. The cross-sectional shape of the clamping arm 7 is set to an "F" shape, which facilitates the sleeve 6 to move in the opposite direction along the adjusting rod 4 as the adjusting rod 4 rotates. As the sleeve 6 moves, the sleeve 6 drives the clamping arm 7 to slide relative to the limiting sleeve 8, so that the clamping arm 7 is disengaged from the clamping plate 10. This allows the user to disassemble the surge protector body 9 and improves the stability of the connection between the clamping arm 7 and the sleeve 6.

[0024] The surge protector body 9 and the positioning frame 1 are fitted together, and the positioning frame 1 and the clamping plate 10 are slidably set so that when the user moves and disassembles the surge protector body 9, the surge protector body 9 drives the clamping plate 10 to slide relative to the positioning frame 1.

[0025] The limiting mechanism 12 includes a knob 1201, a clamping plate 1202, and an anti-slip pad 1203. The knob 1201 is movably installed on the inner wall of the limiting frame 11, and the clamping plate 1202 is movably provided at the end of the knob 1201. The anti-slip pad 1203 is fixedly connected to the outer side wall of the clamping plate 1202 away from the knob 1201. This facilitates the positioning of the cable connected to the surge protector body 9 through the limiting mechanism 12, thereby ensuring a stable connection between the cable and the surge protector body 9, and thus enabling the surge protector body 9 to work stably.

[0026] The knob 1201 and the limiting frame 11 are threaded together, and the knob 1201 and the clamp 1202 are rotatable. The clamp 1202 and the limiting frame 11 are slidably connected, which makes it easy for the user to rotate the knob 1201 so that the knob 1201 moves relative to the limiting frame 11, thereby pushing the clamp 1202 to slide relative to the limiting frame 11. This causes the clamp 1202 to drive the anti-slip pad 1203 to adhere to the cable connected to the surge protector body 9, thereby completing the positioning of the cable.

[0027] Working principle: When using this photovoltaic surge protector, firstly as follows... Figure 1-4 As shown, the user connects the support leg 2 to the working location of the photovoltaic surge protector via the positioning bolt 3, thus completing the installation of the surge protector body 9. Next, the user passes the cable through the positioning frame 1, the limiting bracket 11, and the anti-slip pad 1203. Then, the user connects the cable to the surge protector body 9, thus connecting the surge protector body 9 to the photovoltaic system. The user then rotates the knob 1201, causing the knob 1201 to move relative to the limiting bracket 11. Next, the knob 1201 pushes the clamping plate 1202 to slide relative to the limiting bracket 11. The clamping plate 1202 then causes the anti-slip pad 1203 to adhere to the cable. As the user continues to rotate the knob 1201, the anti-slip pad 1203 presses the cable against the positioning frame 1. At this point, the device limits the cable, thus ensuring the connection between the cable and the surge protector body 9. Stability is ensured, allowing the surge protector body 9 to operate stably. When the surge protector body 9 malfunctions, the user disconnects the cables from the surge protector body 9. Then, the user rotates the adjusting rod 4, and the sleeve 6 moves in the opposite direction along the adjusting rod 4. As the adjusting rod 4 continues to rotate, the sleeve 6 eventually moves and engages with the retaining ring 5. As the sleeve 6 moves, it causes the locking arm 7 to slide relative to the limiting sleeve 8, thereby disengaging the locking arm 7 from the locking plate 10. Subsequently, the user moves the surge protector body 9 away from the device, and as the surge protector body 9 moves, it causes the locking plate 10 to disengage from the positioning frame 1, thus completing the disassembly of the surge protector body 9. Therefore, the photovoltaic surge protector is easy to disassemble from the work site, facilitating user maintenance of the photovoltaic surge protector and improving the practicality of the device.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
