The worm gear 48 is adopted for transmission, so that the transmission system has a self-locking capacity, and the transmission stability is improved.

In this embodiment, a cavity 211 is formed inside the housing 21, an air blowing port 212 communicating with the cavity 211 is formed on an inner wall of the housing 21, and a plurality of air inlets 213 communicating with the cavity 211 are formed on an outer wall of the housing 21.

In this embodiment, a rotary disc 291 is further connected to an output shaft of the cleaning motor 27, a rotary shaft 292 is disposed on the rotary disc 291, the rotary shaft 292 is rotatably connected to one end of a connecting rod 293, the other end of the connecting rod 293 is hinged to a piston 294, the piston 294 is slidably connected to an inflating cylinder 295, an air suction port 296 and an air outlet 297 are disposed on the inflating cylinder 295, and the air suction port 296 is communicated with the air inlet 213 through an air pipe. By utilizing the crank slider principle, the beating cylinder 295 which moves repeatedly is designed, the function of blowing warm air can be added in the cleaning process, and the dust can be further cleaned.

In this embodiment, a first check valve is disposed at the air inlet 296, a second check valve is disposed at the air outlet 297, a first check valve is conducted from the outside of the inflating cylinder 295 to the inside of the inflating cylinder 295, and a second check valve is conducted in a direction opposite to the first check valve. Two check valves are arranged, so that unidirectional flow of air flow is guaranteed, and the function of continuous inflation is realized.

In this embodiment, a dust blocking plate 214 is disposed in the housing 21, and the dust blocking plate 214 is located above the rotation gear 24 and is rotatably connected to the cleaning brushes 23. The rotation gear 24 is combined with the gear ring to provide the cleaning brush 23 with rotation motion, so that the cleaning capability is improved. The dust blocking plate 214 may act as a dust blocking function for the rotation gear 24 and the ring gear 25.

In this embodiment, the protective cover 3, the housing 21, the lifting platform 41, the hollow tube 45, the sliding rod 46 and the base 44 are all made of insulating plastic. Insulating plastics, avoid the thunder and lightning to cause the harm to part itself.

In this embodiment, a supporting plate 32 is disposed in the protective cover 3, the housing 21 is fixedly connected to the supporting plate 32, a protruding structure 33 is disposed on the top of the protective cover 3, and the bottom of the lightning rod 1 is grounded through a conducting wire. The support plate 32 is used to mount the stationary housing 21. The raised formation 33 increases the height of the through-hole 31 and reduces the likelihood of rain water accumulating and possibly entering the housing 21.

In this embodiment, the cleaning motor 27 and the lifting motor 42 are connected to a remote computer for control.

The working process and the principle thereof are as follows:

when the lightning rod 1 is normally used for lightning protection, the lifting platform 41 is positioned at the highest position, most of the lightning rod 1 extends out and is exposed, and a part of the lightning rod 1 at the bottom is still positioned in the shell 21 of the cleaning device 2.

The time of the clearance of lightning rod 1 is the fine day of preferred selection, can avoid when the clearance having a small amount of rainwater to enter into inside the casing 21, and maintainer is long-range through remote computer start elevator motor 42 and clearance motor 27.

The lifting motor 42 drives the worm 48 to rotate, the worm 48 drives the screw 43 to rotate through the worm wheel 47, the screw 43 rotates inside the hollow tube 45, and the hollow tube 45 is internally provided with threads matched with the screw 43, so that when the screw 43 rotates, the lifting platform 41 can be driven to descend, the sliding rod 46 plays a role in limiting sliding, the lifting platform 41 descends, the lightning rod 1 fixed above the lifting platform also descends correspondingly, and the lightning rod 1 passes through the shell 21 little by little. The worm gear 48 is adopted for transmission, so that the transmission system has a self-locking capacity, and the transmission stability is improved.

When lightning rod 1 descends, cleaning motor 27 starts, it is rotatory to drive driven gear 26 through driving gear 28, because driven gear 26 is fixed connection in the bottom of roating seat 22, so roating seat 22 also can follow the rotation, when roating seat 22 is rotatory, it can clear up round lightning rod 1 to rotate cleaning brush 23 of connection on roating seat 22, increase rotation gear 24 in cleaning brush 23's bottom, rotation gear 24 is with the meshing of fixed connection's ring gear 25 on the casing 21, when roating seat 22 is rotatory, rotation gear 24 begins the rotation under the effect of meshing, thereby give an rotation of cleaning brush 23, the revolution of cleaning brush 23 can realize the clearance of covering entirely, the efficiency of clearance can be improved to the rotation.

The cleaning motor 27 rotates and simultaneously drives the rotary disc 291 to rotate, because one end of the connecting rod 293 is rotatably connected to the rotating shaft 292 of the rotary disc 291, the connecting rod 293 performs a planar compound motion, at this time, the rotary disc 291, the connecting rod 293 and the piston 294 form a crank slider mechanism, the piston 294 performs a reciprocating motion in the inflating cylinder 295, when the piston 294 is pulled outwards, the first check valve of the air inlet 296 is conducted, the second check valve of the air outlet 297 is closed, the air inlet 296 admits air, when the piston 294 pushes inwards, the first check valve of the air inlet 296 is closed, the second check valve of the air outlet 297 is conducted, the air in the inflating cylinder 295 flows through the air inlet 213 through an air pipe and enters the casing 21, because the piston 294 generates heat due to friction, the air entering the casing 21 has a certain temperature, the inflating cylinder 295 inflates air into the casing 21 continuously, and because the air outlet speed is lower than the inflating speed, the gas is further pressurized and heated, then is sprayed out from the air blowing port 212, and is used for cleaning the dust on the cleaning brush 23 and the lightning rod 1, and the air with the temperature can also be used for drying the lightning rod 1, so that the corrosion of the lightning rod 1 is reduced, and the air with the dust is discharged from the through hole 31 above, so that the dust is prevented from being accumulated in the shell 21.

The in-process of cleaning device 2 clearance, lightning rod 1 is downward motion always, and is relative, and cleaning device 2 is from up clearing up the surface of lightning rod 1 down and can be all clear up once, prevents that the dust from adhering to influence the effect of drawing thunder, and the maintenance clearance of while regularity also can improve the life of lightning rod 1. The operation time of the elevating motor 42 is determined according to the height at which the elevating platform 41 can be raised and lowered, and when the elevating platform 41 is operated to the maximum point, the elevating motor 42 is automatically stopped. The maintenance personnel can start the lifting motor 42 again, at this moment, the lifting platform 41 starts to ascend again, and the lightning rod 1 is lifted again to meet the lightning protection requirement. At the highest point of the lightning rod 1 elevation, the cleaning motor 27 and the lifting motor 42 are turned off simultaneously.

Most parts in the device are made of insulating materials, so that damage to the parts and an actuator caused by lightning can be reduced.

Based on the above: the rotation of cleaning brush adds the revolution and can satisfy the omnidirectional clearance demand of lightning rod, and it can increase gaseous impact for the clearance process to inflate the jar and combine with the casing, improves cleaning efficiency, also can be with the air discharge casing that has the dust simultaneously outside.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
