Description

Technical Field

[0001] The utility model belongs to the technical field related to lightning arresters, and particularly relates to an automatic cleaning device for end caps of lightning arresters. Background Art

[0002] A lightning arrester is an electrical appliance used to protect electrical equipment from the harm of high transient overvoltages during lightning strikes, limit the follow - current time, and often limit the follow - current amplitude. A lightning arrester is sometimes also called an over - voltage protector or over - voltage limiter. A lightning arrester includes an insulator, an insulating post, a wiring changer, an end cap, etc. Since the flange material of the end cap of the lightning arrester is mostly made of iron, in order to prevent rust, anti - rust oil and other materials are applied to the internal thread during processing for anti - rust treatment. When in use, the internal anti - rust oil and stains need to be cleaned; however, there are still the following drawbacks in the actual cleaning operation:

[0003] Currently, when cleaning the end cap of a lightning arrester, it is mostly cleaned with a brush in a rectangular container, with low efficiency and unclean cleaning, and the cleaning effect is not good.

[0004] Secondly, most of the end - cap flanges of lightning arresters are of a hollow cylindrical structure, which is inconvenient to clamp during cleaning. If mechanically cleaned, it is difficult to ensure that the inner cavity of the end cap is facing the cleaning component directly, and a stable clamping structure is required for assistance.

[0005] Finally, the cleaning agent has a pungent smell and is completely exposed, which is harmful to the human body and needs to be protected. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an automatic cleaning device for end caps of lightning arresters. By setting a cleaning tank, a motor, a cleaning brush, a clamping rod, a clamping plate, a clamping jaw, a clamping spring, and a sealing cover, the problems of low cleaning efficiency and unclean cleaning of the end cap of the lightning arrester, lack of a stable clamping structure for cleaning the end cap of the lightning arrester, and excessive smell of the cleaning agent used during cleaning of the lightning arrester, which is harmful to the human body, are solved.

[0007] To solve the above - mentioned technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model is an automatic cleaning device for end caps of lightning arresters, including a cleaning tank, a foot switch, a sealing cover, a clamping rod, and a motor. The bottom of the cleaning tank is fixed with a bottom plate. The center of the bottom surface of the bottom plate is fixed with a motor, and a foot switch is arranged below the motor. The output end of the motor penetrates through the bottom plate and is fixed with a cleaning shaft, and the cleaning shaft rotates at the bottom of the inner part of the cleaning tank. A cleaning brush is arranged at the upper end of the cleaning shaft. A bolt is inserted into the cleaning brush, and the lower part of the bolt passes through the cleaning brush and is screwed into a threaded hole opened at the upper end of the cleaning shaft.

[0009] The upper end cover of the cleaning tank is provided with a sealing cover. Two symmetrical through grooves are formed in the sealing cover. A sliding rod is fixed in each through groove. Clamping springs are fixed at one ends of the two through grooves close to each other. End plates are fixed at the ends of the two clamping springs away from each other.

[0010] A clamping rod is arranged through the center of the sealing cover. The lower part of the clamping rod extends into the cleaning tank, and hinge members are symmetrically arranged on the outer peripheral surface thereof. Each hinge member is hinged with a clamping jaw. A clamping plate is fixed at the upper end of each clamping jaw. The upper part of the clamping plate penetrates through the through groove and extends out, and the end plate contacts the surface of the clamping plate located in its corresponding through groove.

[0011] Furthermore, three legs distributed in an annular array are fixed on the outer periphery of the cleaning tank. The outer side of the bottom plate is fixed to the inner side surfaces of the three legs. Side plates are fixed between every two adjacent legs below the bottom plate.

[0012] Furthermore, the electric control end of the foot switch is electrically connected to the electric input end of the motor.

[0013] Furthermore, a strip-shaped groove is formed on the inner side of the clamping plate, and the clamping plate is sleeved outside the sliding rod through the strip-shaped groove. The two clamping plates are respectively located on the opposite sides of the two end plates.

[0014] Furthermore, the clamping spring and the end plate are both sleeved outside the sliding rod in its corresponding through groove.

[0015] Furthermore, the upper end of the clamping rod extends upward through the sealing cover and is fixed with a head end. A return spring sleeved outside the clamping rod is fixed at the bottom of the head end. The bottom end of the return spring is fixed on the upper end surface of the sealing cover.

[0016] Furthermore, symmetrically distributed long strips are fixed on the bottom surface of the sealing cover. Short strips are fixed on the bottom surface of the sealing cover outside both ends of each long strip. A clamping groove is formed between the long strip and the short strip and is clamped outside the upper edge of the cleaning tank.

[0017] The utility model has the following beneficial effects:

[0018] By setting the cleaning tank, the motor, the cleaning brush, the clamping rod and the clamping jaw, the utility model solves the problems of low cleaning efficiency and unclean cleaning of the end cover of the lightning arrester. The end cover is clamped by the clamping jaws at the bottom of the clamping rod, and is placed upside down in the cleaning tank. Then, the cleaning agent is distributed in the cleaning tank. The foot switch is used to control the positive and negative rotation of the motor, driving the positive and negative rotation of the cleaning shaft, driving the positive and negative rotation of the cleaning brush, brushing the inner wall of the end cover, removing substances such as antirust oil on its inner wall. Then, the clamping rod is pressed down to drive the end cover clamped by the clamping jaws to move downwards, so that the cleaning brush can fully contact the inner wall of the end cover. This efficient mechanical cleaning method is more thorough and has higher efficiency.

[0019] The utility model solves the problem of lack of a stable clamping structure for cleaning the end cover of a lightning arrester by setting a clamping rod, clamping plates, clamping claws, a clamping spring, and a cover. When the two clamping plates approach the clamping rod, the clamping spring is further compressed at this time, and the two clamping claws rotate around the hinge shaft. At this time, the clamping claws move away from each other. Place the end cover between the two clamping claws, and then release the clamping plates to make the clamping claws return to their original positions. Under the elastic force of the clamping spring, the clamping plates move away from each other, and the clamping claws clamp the end cover. Then, the end cover can be inserted into the cleaning tank.

[0020] The utility model solves the problem that the cleaning agent used during the cleaning of the lightning arrester has a strong smell and is harmful to the human body by setting a cover. The cover is arranged on the cleaning tank to seal the upper end of the cleaning tank as much as possible, avoiding the emission of a large amount of irritating odors, being able to block a certain amount of odors, and cloth or the like can also be covered on the through groove for use.
