[0032] The cleaning assembly includes four arc plates 6 that are equidistantly distributed around the circumference, and the four arc plates 6 are movably sleeved on the outside of the lightning rod 1. A cleaning brush 7 is fixedly installed on one side of the four arc plates 6 close to the lightning rod 1, and the connection between the cleaning brush 7 and the lightning rod 1 is movably fitted, and the shape of the four cleaning brushes 7 is conical, so that the lightning rod 1 can contact and rub with the cleaning brush 7 during the up and down movement;

[0033] Driven by spring 18, multiple cleaning brushes 7 are also attached to lightning rod 1, and then when lightning rod 1 continues to move downward, multiple cleaning brushes 7 contact and rub with lightning rod 1, so that cleaning brushes 7 can brush away dust accumulated on the surface of lightning rod 1.

[0034] A connecting seat 8 is movably embedded on the side of the arc plate 6 away from the cleaning brush 7, and a pin piece 9 is fixedly connected to the side of the connecting seat 8 close to the arc plate 6. An inserting groove 10 is provided on the arc plate 6 corresponding to the connecting seat 8 and the pin piece 9, and the connecting seat 8 and the pin piece 9 are plugged and unplugged with the arc plate 6 through the inserting groove 10. A U-shaped pin 11 is installed on the pin piece 9, and the U-shaped pin 11 is located on the upper side of the arc plate 6. The U-shaped pin 11 is installed on the pin piece 9, which can prevent the arc plate 6 from detaching from the pin piece 9.

[0035] A through hole 12 is provided at the upper end of the pin piece 9 corresponding to the U-shaped pin 11, and the U-shaped pin 11 is movably plugged with the pin piece 9 through the through hole 12, a push rod 13 is fixedly embedded at the lower end of the connecting seat 8, a limiting straight groove 33 is provided at the upper end of the supporting tube 2 corresponding to the push rod 13, and the push rod 13 is in sliding contact with the supporting tube 2 through the limiting straight groove 33, and a ball 14 is movably embedded at the lower end of the push rod 13, and the ball 14 is used to reduce the friction resistance between the push rod 13 and the conical seat 5, and the connection between the ball 14 and the conical seat 5 is rolling contact;

[0036] Therefore, the personnel can first remove the U-shaped pin 11 from the pin piece 9, and then under the condition that the connecting seat 8 and the pin piece 9 are plugged and unplugged with the arc plate 6 through the plug-in groove 10, the personnel can remove the arc plate 6 from the pin piece 9, which is convenient for the personnel to replace the aging cleaning brush 7.

[0037] A connecting rod 15 is fixedly installed on the outer side of the top rod 13, and a gasket 16 is fixedly connected to the end of the connecting rod 15 away from the top rod 13. A sleeve 17 is movably sleeved on the outer side of the gasket 16, and the sleeve 17 is fixedly embedded in the side wall of the support tube 2. A spring 18 is movably abutted on the side of the gasket 16 away from the connecting rod 15. The spring 18 is used to drive the cleaning brush 7 to fit the lightning rod 1, and the end of the spring 18 away from the gasket 16 is movably abutted against the sleeve 17.

[0038] A rubber ring 31 is fixedly sleeved on the outer side of the base 4, and the rubber ring 31 is movably fitted with the inner wall of the support tube 2. The rubber ring 31 is used to prevent rainwater from flowing to the bottom of the support tube 2 and affecting the lifting rod 3. A plurality of drainage grooves 32 are equidistantly distributed on the circumference of the support tube 2. A grounding wire 34 is fixedly installed at the lower end of the base 4.

[0039] In rainy and snowy weather, rain and snow will flow into the interior of the support tube 2 through the limiting straight groove 33 of the top rod 13. After entering the interior of the support tube 2, the rain and snow will be blocked by the rubber ring 31 on the outside of the support plate 24, and discharged from the interior of the support tube 2 through the drainage groove 32 on the upper side of the rubber ring 31, which can effectively prevent rain and snow from flowing to the bottom of the support tube 2 and accumulating at the bottom of the support tube 2, affecting the normal operation of the lifting rod 3.

[0040] Working principle: when the lightning rod 1 is in operation, the lifting rod 3 inside the supporting tube 2 supports the lightning rod 1. When it is necessary to clean the dust accumulated on the surface of the lightning rod 1, the lifting rod 3 drives the lightning rod 1 and the conical seat 5 to move downward. During the downward movement of the conical seat 5, the ball 14 at the lower end of the top rod 13 rolls along the surface of the conical seat 5 driven by the compression force of the spring 18, and the multiple cleaning brushes 7 also fit the lightning rod 1 under the drive of the spring 18. Then, during the process of the lightning rod 1 continuing to move downward, the multiple cleaning brushes 7 contact and rub with the lightning rod 1, so that the cleaning brushes 7 can brush away the dust accumulated on the surface of the lightning rod 1.

[0041] When the lightning rod 1 is cleaned, the lifting rod 3 drives the lightning rod 1 to move up and reset, and the conical seat 5 drives the multiple push rods 13 to move away from each other through the ball 14, so that the multiple cleaning brushes 7 move away from the lightning rod 1, which can effectively prevent the cleaning components from interfering with the normal operation of the lightning rod 1.

[0042] Example 2: Please refer to Figure 7 , Figure 8This embodiment further explains Example 1. The protection component includes four positioning blocks 19 fixedly mounted on the upper end of the support tube 2, and the four positioning blocks 19 are equidistantly distributed on the circumference. A protective cover 20 is installed between two adjacent positioning blocks 19, and the protective cover 20 is located on the upper side of the cleaning component. The protective cover 20 is rotatably connected to the positioning block 19 through a connecting shaft 21. The protective cover 20 covers the outer side of the cleaning brush 7 to extend the service life of the cleaning brush 7. A counterweight bar 22 is fixedly mounted on the side of the protective cover 20 away from the lightning rod 1, and a stopper 23 is fixedly embedded on the positioning block 19 corresponding to the lower side of the protective cover 20.

[0043] In this embodiment: the cleaning brush 7 away from the lightning rod 1 moves to the lower side of the protective cover 20 under the drive of the conical seat 5, and the protective cover 20 covers the cleaning brush 7, which can effectively reduce the impact of the external environment on the cleaning brush 7, slow down the aging of the cleaning brush 7, and thus extend the service life of the cleaning brush 7.

[0044] Example 3: Please refer to Figure 2 , Figure 7 , Figure 8 This embodiment further explains the second embodiment. A support assembly is installed between the protective cover 20 and the conical seat 5. A support plate 24 is fixedly sleeved on the outer side of the base 4, and the shape of the support plate 24 is annular. The support assembly includes a second push rod 25 that is plugged and unplugged with the support tube 2. A retaining ring 1 26 and a retaining ring 27 are fixedly sleeved on the outer side of the second push rod 25 corresponding to the inner side of the support tube 2. A positioning plate 28 is movably sleeved on the outer side of the second push rod 25, and the connection between the positioning plate 28 and the support tube 2 is a fixed connection. The retaining ring 1 26 is used to prevent the second push rod 25 from being separated from the positioning plate 28.

[0045] The positioning plate 28 is located between the retaining ring 1 26 and the retaining ring 27. The outer side of the push rod 25 is located between the retaining ring 27 and the positioning plate 28 and is movably sleeved with a spring 29. The two ends of the spring 29 are respectively movably abutted with the retaining ring 27 and the positioning plate 28. Both ends of the push rod 25 are provided with a hemispherical portion 30. The push rod 25 is movably abutted with the protective cover 20 and the support plate 24 through the hemispherical portion 30, and the push rod 25 can support the protective cover 20.

[0046] In this embodiment, when the lifting rod 3 drives the lightning rod 1 to move downward for cleaning, the support plate 24 will also move downward with the lightning rod 1. At this time, the top rod 25 will move downward under the drive of the compression force of the spring 29 until the retaining ring 1 26 and the positioning plate 28 abut against each other. In this process, since the protective cover 20 is in an inclined state (see the attached manual), the protective cover 20 is inclined. Figure 2As can be seen, the protective cover 20 will rotate and open under the gravity of the counterweight bar 22, so that when the cleaning brush 7 cleans the dust on the surface of the lightning rod 1, the cleaning brush 7 is exposed, which is conducive to the natural wind to blow away the dust brushed off the lightning rod 1 by the cleaning brush 7. When the lightning rod 1 moves up and resets, the base 4 drives the multiple top rods 25 to move up through the supporting plate 24. The top rods 25 drive the protective cover 20 to rotate and reset through the hemispherical part 30 during the upward movement.

[0047] When the cleaning brush 7 needs to be replaced, the personnel controls the support plate 24 to move away from the top rod 25, so that the multiple protective covers 20 are rotated and opened. Since the cleaning brush 7 is exposed at this time, the personnel can first remove the U-shaped pin 11 from the pin piece 9, and then under the condition that the connecting seat 8 and the pin piece 9 are plugged and unplugged with the arc plate 6 through the plug-in groove 10, the personnel can remove the arc plate 6 from the pin piece 9, which is convenient for personnel to replace the aged cleaning brush 7.
