[0002] Publication number "CN215646109U" discloses an electrical equipment lightning protection device, including an adjusting and fixing mechanism. The adjusting and fixing mechanism includes a rectangular box, a screw, a horizontal plate, a knob, a rectangular rod, and ball bearings; the rectangular box has openings on both sides. When the device needs to be installed on the outside of electrical equipment to achieve lightning protection, rotating the knob moves the screw, causing the horizontal plate to move forward. The horizontal plate, through the rectangular rod, moves the corresponding ball bearings to press against the inclined surface of a triangular block. The triangular block moves the corresponding horizontal rod to compress a spring. The horizontal rod moves the corresponding rectangular plate, causing the rectangular plate to move. The rectangular plate then causes two corresponding rectangular rubber anti-slip blocks to fit tightly against the outside of the electrical equipment, thus achieving a fixing effect. Rotating the screw separates the device from the connecting block, and then moving the connecting block upwards separates the connecting block from the top of the rectangular box. The connecting block moves the lightning rod, allowing the lightning rod to be removed and replaced.

[0017] 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.

[0018] Example: Figure 1-5 As shown, this utility model provides a lightning protection device for electrical equipment, including a rectangular box 1. A lightning rod 11 is provided at the top of the rectangular box 1, and a mounting base 12 is fixedly installed at the bottom of the lightning rod 11. Two sets of symmetrically distributed plug blocks 13 are fixedly installed at the bottom of the mounting base 12. A slot 14 for cooperating with the plug blocks 13 is opened through the upper surface of the rectangular box 1. Two symmetrically distributed fixing blocks 15 are fixedly installed on the lower surface of the inner wall of the rectangular box 1. A double-ended screw 16 with opposite threads is rotatably passed through the bottom of the fixing block 15. Two symmetrically distributed moving plates 17 are threaded to the outer side of the double-ended screw 16. Two symmetrically distributed plug rods 18 are fixedly installed on the side of the moving plate 17 near the fixing block 15. A fixing groove 19 for cooperating with the plug rods 18 is opened through the bottom of the plug block 13. One end of the double-ended screw 16 rotatably passes through the rectangular box 1, and a first rotating wheel 10 is fixedly installed at the end of the double-ended screw 16.

[0019] A protective frame 2 is fixedly installed on the side of the rectangular box 1 near the first rotating wheel 10. The first rotating wheel 10 is located in the protective frame 2. A door 21 is hinged to the side of the protective frame 2 away from the rectangular box 1.

[0020] A support block 3 is fixedly installed at the middle position of the upper surface of the inner wall of rectangular box 1. A guide rod 31 is fixedly inserted through the top of the support block 3. Two symmetrically distributed connecting plates 32 are slidably sleeved on the outside of the guide rod 31. The connecting plates 32 slide through the rectangular box 1. A clamping plate 33 is fixedly installed on the side of the connecting plate 32 away from the rectangular box 1. A fixing seat 34 is fixedly installed on the upper surface of the inner wall of rectangular box 1. A screw 30 is rotatably inserted through the top of the fixing seat 34. A T-shaped block 35 is threadedly connected to the outside of the screw 30. Inclined plates 37 are rotatably connected to the upper and lower sides of the two connecting plates 32 through a rotating shaft. The inclined plates 37 are located at the edge of the connecting plates 32. The inclined plates 37 and the T-shaped blocks 35 are rotatably connected through a rotating shaft. One end of the screw 30 rotatably inserts through the rectangular box 1. Furthermore, a second rotating wheel 38 is fixedly installed at the end of the screw 30. The second rotating wheel 38 is located in the protective frame 2. By setting the screw 30, when the second rotating wheel 38 is rotated, the screw 30 is driven to rotate. The rotation of the screw 30 drives the T-shaped block 35 to move towards the fixed seat 34. During the movement of the T-shaped block 35, the connecting plate 32 is pushed to slide on the guide rod 31 by the inclined plate 37. The movement of the connecting plate 32 drives the clamping plate 33 to move to both sides, and then the bottom surface of the rectangular box 1 is attached to the top surface of the electrical equipment. Then, the second rotating wheel 38 is rotated in the opposite direction, so that the screw 30 reverses and drives the T-shaped block 35, the connecting plate 32, and the clamping plate 33 to move back, so that the clamping plate 33 is attached to the electrical equipment, thereby realizing the installation between the electrical equipment and the electrical equipment.

[0021] A limiting rod 4 is fixedly installed between two fixed blocks 15, and two movable plates 17 are slidably sleeved on the outside of the limiting rod 4. By setting the limiting rod 4, the movable plates 17 are limited, so that when the double-headed screw 16 rotates, it can drive the movable plates 17 to move to both sides or to the middle.

[0022] Each insertion rod 18 is externally fixed with several uniformly spaced annular stabilizing plates 5. Each insertion block 13 is located at the position of the fixing groove 19 and has a through-hole stabilizing groove 51 that works with the stabilizing plate 5. By setting the stabilizing plate 5, when the insertion rod 18 is inserted into the corresponding fixing groove 19, the stabilizing plate 5 is also inserted into the corresponding stabilizing groove 51, thereby making the insertion rod 18 inserted into the fixing groove 19 more stable.

[0023] A rain shield 6 is fixedly installed at the top of the protective frame 2. The length and width of the rain shield 6 are the same as the length and width of the protective frame 2. By setting the rain shield 6, the first rotating wheel 10 and the second rotating wheel 38 are further protected from rain, preventing rainwater from entering the protective frame 2 from the gap between the protective frame 2 and the door 21. When in use, a sealing gasket can be installed in the gap between the protective frame 2 and the door 21.

[0024] Limiting blocks 7 are fixedly installed on both the left and right sides of the two connecting plates 32. The limiting blocks 7 are installed on one side edge close to the support block 3. By setting the limiting blocks 7, the connecting plates 32 are prevented from detaching from the guide rod 31 and the rectangular box 1 when they move to both sides, which would affect the back movement of the connecting plates 32 and the fixation of the electrical equipment.

[0025] Anti-slip pads 8 are fixedly installed on the side of both clamps 33 near the rectangular box 1. By setting anti-slip pads 8, the friction with electrical equipment is increased, preventing the equipment from shaking or slipping.

[0026] Working principle: In actual use, when it is necessary to install the lightning rod 11 on the rectangular box 1, insert each plug 13 into the corresponding slot 14 so that the mounting base 12 fits against the rectangular box 1. Then, open the door 21 by the handle, and then rotate the first rotating wheel 10 to drive the double-headed screw 16 to rotate. The moving plate 17 is limited by the limiting rod 4, so that the double-headed screw 16 drives the moving plate 17 and the plug rod 18 to move towards the fixing groove 19 on the limiting rod 4, and so that the plug rod 18 is fully inserted into the corresponding fixing groove 19. Then, close the door 21. When it is necessary to disassemble, simply rotate the first rotating wheel 10 in the opposite direction.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
