Description

Technical Field

[0001] This invention relates to the field of electromechanical equipment technology, and in particular to a safety live-line cleaning device for electrical equipment. Background Technology

[0002] Electrical equipment is a general term for equipment such as generators, transformers, power lines, and circuit breakers in a power system. After prolonged operation, dirt will accumulate on the surface of electrical equipment. If the amount of dirt accumulation is large, it will affect the heat dissipation and contact stability of the electrical equipment. Therefore, it is necessary to clean the dirt on the surface of the electrical equipment.

[0003] Existing cleaning equipment uses high-pressure jet sprayers to apply insulating cleaning fluid to the surface of electrical equipment. This works by dissolving contaminants in the fluid and washing them away with the high-pressure airflow. However, contaminants and cleaning fluid can easily splash onto surrounding equipment, potentially contaminating other devices and causing secondary pollution, requiring additional cleaning. High-pressure airflow can also cause physical damage to electrical equipment, especially fragile or delicate components. Furthermore, high-pressure jets may not clean all surfaces evenly, particularly hard-to-reach corners and crevices. The cleaning fluid used can pollute the environment, especially if it contains harmful chemicals. Finally, using high-pressure jet equipment and insulating cleaning fluid can be costly, particularly for frequent cleaning applications. Summary of the Invention

[0004] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, the present invention provides a safety live-line cleaning device for electrical equipment.

[0005] The technical solution includes an insulating shell, an insulating rope, and an insulating support rod. Multiple insulating balls are fixedly installed on the insulating rope. The insulating shell contains a recovery channel, a connecting channel, an air jet channel, and a sponge tube. The inner side of the sponge tube has multiple evenly distributed annular protrusions. Inside the sponge tube, there are also six support rods arranged in a circular array around the sponge tube. One end of each support rod is fixedly connected to a fixed end cap, and the other end is fitted with a movable end cap. The inner ring of the movable end cap is threaded. One end of the recovery channel is connected to the sponge tube via the fixed end cap, and the other end of the recovery channel is connected to one end of the connecting channel. The other end of the connecting channel is connected to the middle of the air jet channel. A tube brush is screwed onto the sponge tube via the threads on the movable end cap. The tube brush includes an externally threaded tube, and several bristle holes are drilled on the inner wall of the externally threaded tube. A bundle of insulating brush filaments is implanted into each bristle hole.

[0006] Preferably, the front end of the insulating housing is fixedly connected to an air outlet that communicates with the jet channel, and the rear end of the insulating housing is fixedly connected to an air inlet that communicates with the jet channel. The air inlet is connected to the air outlet of the air compressor through an air delivery pipe. The inner diameter of the jet channel, the inner diameter of the recovery channel, and the inner diameter of the connecting channel are the same.

[0007] Preferably, a countersunk hole is provided above the jet channel, the countersunk hole is connected to the jet channel, and a nozzle is screwed onto the countersunk hole. The nozzle is connected to a container containing insulating cleaning fluid through an infusion hose.

[0008] Preferably, the rounded corners reduce the impact on the insulating rope and the insulating ball. The front part of the externally threaded cylinder is provided with an outwardly extending flange, and the junction of the flange and the inner side of the externally threaded cylinder is rounded.

[0009] Preferably, the insulating rope comprises multiple woven rope cores and several insulating fiber bundles sandwiched between the rope cores. The rope cores are made of polyethylene terephthalate, and the insulating fiber bundles are composed of one or more of quartz fiber, mica fiber, glass fiber, and asbestos fiber. The first end of the insulating rope passes sequentially through the tube brush, the rear of the recycling channel, the connecting channel, and the air jet channel, and is then fixedly connected to the tail end of the insulating rope, so that the insulating rope is connected into a ring structure.

[0010] Preferably, the outer diameter of the insulating ball in its natural state is larger than the inner diameter of the jet channel, and the outer diameter of the insulating ball in its fully compressed state is smaller than the inner diameter of the jet channel.

[0011] Preferably, the front part of the insulating support rod is screwed to the rear part of the insulating housing.

[0012] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: High-pressure air enters the jet channel and pushes the insulating ball from back to front. The insulating cleaning fluid enters the jet channel 4 through the nozzle 10 and the countersunk hole 7, so that the insulating cleaning fluid is sprayed onto the insulating rope 2 and the insulating ball 21. The insulating rope and the insulating ball 21 sprayed from the air outlet 8 wipe and collide to clean the surface of the electrical equipment to be cleaned, so that the dirt on the surface of the electrical equipment is carried away by the insulating rope 2 and the insulating ball 21. At the same time, the insulating rope 2 and the insulating ball 21 outside the insulating shell are dragged sequentially through the drum brush 16, the sponge cylinder 11, the recovery channel 5 and the connecting channel 6, and the dirt on the surface of the insulating rope 2 and the insulating ball 21 is removed after passing through the drum brush 16 and the sponge cylinder 11. The cleaning process is repeated once the insulating rope 2 and insulating ball 21 are removed, and then returned to the jet channel 4. This cycle cleans the electrical equipment without splashing the insulating cleaning fluid and dirt onto surrounding electrical equipment. In addition, the sponge cylinder 11 and the brush 16 are detachable. After cleaning for a period of time, they are stored in the sponge cylinder and the brush and can be removed. Since the device is made of insulating materials, it can clean electrical equipment while it is energized, preventing dirt and insulating cleaning fluid from splashing onto the surface of surrounding electrical equipment. The materials and equipment required for this device are all conventional materials, which are simple to manufacture, easy to obtain, and inexpensive. The structure is simple, easy to assemble and disassemble, and has a wide range of applications. It is easy to operate and can be widely used. Attached Figure Description

[0024] Example 1

[0025] See Figures 1 to 4This invention provides a safety live-line cleaning device for electrical equipment, comprising an insulating shell 1, an insulating rope 2, and an insulating support rod 3. Multiple evenly distributed insulating balls 21 are fixedly installed on the insulating rope 2. The interior of the insulating shell 1 includes a recovery channel 5 parallel to its long axis, an arc-shaped connecting channel 6, an air jet channel 4 parallel to its long axis and penetrating the insulating shell, and a sponge tube 11. The inner side of the sponge tube 11 has multiple evenly distributed annular protrusions 12 to increase the surface area of ​​the inner surface of the sponge tube 11. The annular protrusions can be made of flexible materials such as sponge or foam. Inside the sponge tube 11, there are also six support rods 13 arranged in a circular array around the sponge tube 11. One end of each support rod 13 is fixedly connected to a fixed end cap 14, and the other end of each support rod 13 is equipped with a movable end cap 14. The movable end cap 15 has a threaded inner ring. One end of the recovery channel 5 is connected to the sponge tube 11 through the fixed end cap 14. The movable end cap 15, the fixed end cap 14, and the six support rods 13 work together to support the sponge tube 11 and prevent it from being pulled and deformed when the insulating rope 2 moves. The other end of the recovery channel 5 is connected to one end of the connecting channel 6, and the other end of the connecting channel 6 is connected to the middle of the air jet channel 4. The sponge tube 11 is screwed with a tube brush 16 through the thread on the movable end cap 15. The tube brush 16 includes an external threaded tube 17. Several hair-implanting holes are drilled on the inner side wall of the external threaded tube 17. A bundle of insulating brush filaments 18 is implanted in each hair-implanting hole. The front part of the external threaded tube 17 is provided with an outwardly extending flange 20. The flange 20 facilitates the disassembly and assembly of the tube brush 16.

[0026] Specifically, the front end of the insulating housing 1 is fixedly connected to an air outlet 8 that communicates with the jet channel 4, and the rear end of the insulating housing 1 is fixedly connected to an air inlet 9 that communicates with the jet channel 4. The air inlet 9 is connected to the air outlet of the air compressor through an air delivery pipe. The inner diameter of the jet channel 4, the inner diameter of the recovery channel 5, and the inner diameter of the connecting channel 6 are the same.

[0027] Specifically, a countersunk hole 7 is provided above the jet channel 4. The countersunk hole 7 is connected to the jet channel 4. A nozzle 10 is screwed onto the countersunk hole 7. The nozzle 10 is connected to a container containing insulating cleaning fluid through an infusion hose.

[0028] Specifically, the fillet 19 reduces the impact on the insulating rope 2 and the insulating ball. The front of the external threaded cylinder 17 is provided with an outwardly extending flange 20, and the junction of the flange 20 and the inner side of the external threaded cylinder 17 is a fillet 19.

[0029] Specifically, the insulating rope (2) includes multiple braided rope cores and several insulating fiber bundles sandwiched between the rope cores. The rope cores are made of polyethylene terephthalate, and the insulating fiber bundles are made of one or more of the following: quartz fiber, mica fiber, glass fiber, and asbestos fiber. The first end of the insulating rope 2 passes through the tube brush 16, the sponge tube 11, the rear of the recycling channel 5, the connecting channel 6, and the air jet channel 4 in sequence, and is then fixedly connected to the tail end of the insulating rope 2, so that the insulating rope 2 is connected into a ring structure.

[0030] Specifically, the outer diameter of the insulating ball 21 in its natural state is larger than the inner diameter of the jet channel 4, and the outer diameter of the insulating ball 21 in its fully compressed state is smaller than the inner diameter of the jet channel 4.

[0031] Specifically, the front part of the insulating support rod 3 is screwed to the rear part of the insulating housing 1. The rear end center of the housing 1 is provided with a first internal threaded hole 22, and the front end of the support rod 3 is provided with an external threaded post 23, which is screwed into the first internal threaded hole 22.

[0032] Example 2

[0033] See Figures 5 to 6 The difference from Embodiment 1 is that the rear end of the insulating support rod 3 is provided with a second internal threaded hole 24. When the two insulating support rods 3 are connected, the external threaded post 23 at the front of one insulating support rod 3 is screwed into the second internal threaded hole 24 at the rear of the other insulating support rod 3.

[0034] In use, high-pressure air enters the jet channel, propelling the insulating ball from back to front. Insulating cleaning fluid enters the jet channel 4 through the nozzle 10 and countersunk hole 7, spraying onto the insulating rope 2 and insulating ball 21. The insulating rope and insulating ball 21, ejected from the air outlet 8, wipe and collide with the surface of the electrical equipment to be cleaned, carrying away dirt. Simultaneously, the insulating rope 2 and insulating ball 21 outside the insulating shell are dragged sequentially through the cylindrical brush 16, sponge cylinder 11, recovery channel 5, and connecting channel 6. Dirt on the surface of the insulating rope 2 and insulating ball 21 is cleaned as they pass through the cylindrical brush 16 and sponge cylinder 11. The cleaned insulating rope 2 and insulating ball 21 return to the jet channel 4, thus achieving a cycle for cleaning the electrical equipment. Furthermore, the insulating cleaning fluid and dirt do not splash onto surrounding electrical equipment. Additionally, the sponge cylinder 11 and cylindrical brush 16 are detachable and can be removed after a period of cleaning. Because this device is made of insulating materials, it can perform live cleaning of electrical equipment.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
