Description

Technical Field

[0001] The present application relates to the technical field of cleaning tools for electric equipment, and in particular to an electric tool for cleaning the surface of bushings and insulators. Background Art

[0002] The surface of bushings and insulators usually adopts the shape of umbrella skirts or umbrella edges. This shape design increases the creepage distance and improves the electrical strength in a dirty state, but it also makes cleaning more difficult: its undulating surface makes it more difficult to clean, and because it can only be cleaned during power outages, the cleaning frequency is low, and a lot of dust accumulates on the surface. Therefore, a tool that can efficiently clean the surface of bushings and insulators is needed.

[0003] Usually, substations use rags dipped in high-purity liquid alcohol to wipe the surface of bushings and insulators. High-purity liquid alcohol can wet the rag on one hand, which helps to wipe off the dust on the surface of bushings and insulators. On the other hand, alcohol can evaporate quickly to prevent the liquid remaining in the bushings and insulators from flashing when power is transmitted. Some substations with conditions use handheld electric cleaning tools to use motor-driven brushes to clean the dust on the surface of bushings and insulators.

[0004] However, using a rag dipped in high-purity liquid alcohol to wipe the bushing and insulator has the following disadvantages: 1. Workers often need to climb high when wiping, and there is a risk of falling from a height; 2. The surface of the bushing and insulator is in the shape of an umbrella skirt or umbrella edge, and wiping with a rag is time-consuming and inefficient.

[0005] In addition, the use of handheld electric cleaning tools also has the following disadvantages: 1. The center of gravity of the electric tool is concentrated on the wiping part, and the wiping personnel hold the tool at the end of the operating lever, which makes it difficult to use and affects the wiping effect over a long period of time; 2. Personnel still need to climb to a height to observe the wiping effect, and the risk of falling from a height is not fundamentally eliminated. Summary of the invention

[0006] The present application provides an electric tool for cleaning the surface of bushings and insulators, which can save workers from having to climb high to carry out cleaning work, thereby improving work efficiency and reducing the risk of falling from heights.

[0007] The present application provides an electric tool for cleaning the surface of a bushing or an insulator, which adopts the following technical solution: An electric tool for cleaning the surface of a bushing and an insulator, comprising a bracket, a cleaning module and a cleaning agent pumping module; The cleaning module comprises: A cleaning seat, mounted on the bracket; A full circle of gears, rotatably mounted on the cleaning seat; A gear motor, mounted on the cleaning seat and used to drive the full circle of gears to rotate forward and reverse; A half-circle gear ring is rotatably mounted on the cleaning seat with its axis as the rotation axis, and the outer arc teeth of the half-circle gear ring are meshed and connected with the full-circle gear; The hydraulic telescopic system is provided with two and is respectively installed at the two ends of the inner arc side of the half-circle gear ring; A brush plate is rotatably mounted on the telescopic output end of the hydraulic telescopic system; and A nozzle is arranged on the half-circle gear ring and points to the area between the two brush discs; The cleaning agent pumping module is used for pumping cleaning agent to the nozzle.

[0008] Furthermore, an interconnecting pipeline is provided on the half-circle gear ring, and the outlet of the interconnecting pipeline is connected to the nozzle and the liquid supply end of the hydraulic telescopic system. The cleaning agent pumping module is used to pump cleaning agent into the interconnecting pipeline.

[0009] Furthermore, the hydraulic telescopic system comprises: A fixed cylinder, fixedly connected to the end of the inner arc side of the half-circle gear ring; A movable rod is anti-slip and slidably arranged in the fixed cylinder, and the brush plate is rotatably mounted on the free end of the movable rod; The hydraulic chamber is located in the fixed cylinder and on a side of the movable rod close to the half-circle gear ring, and is communicated with the interconnecting pipeline.

[0010] Furthermore, it also includes: The damping spring is arranged in the fixed cylinder and sleeved on the outer periphery of the movable rod; when the cleaning agent is pumped into the hydraulic cavity, the damping spring is compressed and deformed.

[0011] Furthermore, a cleaning motor is installed at the free end of the movable rod, and the brush plate is installed at the output end of the cleaning motor.

[0012] Furthermore, a hydraulic blade is rotatably mounted on the free end of the movable rod, the brush plate is coaxially fixed to the hydraulic blade, and an impact nozzle connected to the interconnecting pipeline and pointing to the hydraulic blade is provided on the inner arc side of the half-circle gear ring.

[0013] Furthermore, the cleaning agent pumping module comprises: A cleaning agent tank, mounted on the bracket; A hose, one end of which is connected to the interconnecting pipeline on the half-circle gear ring; A pressure pump is used to pump the cleaning agent in the cleaning agent tank into the hose.

[0014] Furthermore, the cleaning seat is provided with a distance measuring member for detecting the distance value between the cleaning seat and the workpiece to be cleaned, the distance measuring member is connected to a controller, and the controller is connected to the pressure pump; The controller is configured to control the pressurizing pump to increase the flow rate of the output cleaning agent when the distance measuring element detects that the distance value increases; and control the pressurizing pump to reduce the flow rate of the output cleaning agent when the distance measuring element detects that the distance value decreases.

[0015] Furthermore, the support comprises: A base having rollers thereon; A lifting rod is installed on the base, and the cleaning seat is installed on the top of the lifting rod.

[0016] Furthermore, a pitch adjustment mechanism is provided between the cleaning seat and the top end of the lifting rod.

[0017] In summary, the present application includes at least one of the following beneficial technical effects: 1. This application makes the cleaning of bushings and insulators safer and more efficient. First, if the operator wipes with a rag, he often needs to use climbing tools such as ladders. Moreover, the bushings and insulators are installed at the highest point of the electrical equipment. Sometimes, even if the operator wears a safety belt, it is difficult to find a hanging point that meets the requirements of "high hanging and low use". With the help of this application, it can be ensured that in most application scenarios, the operator only needs to move the tool position and operate the equipment on the ground without having to climb high; 2. The surface of the bushing and insulator adopts the shape of umbrella skirt or umbrella ridge, so there are many dead angles when wiping with a rag or handheld tools. The present application can flexibly adjust the hydraulic pressure in the interconnecting pipeline through the distance measuring part, appropriately extend or shorten the radial displacement of the brush plate, and appropriately increase or decrease the flow rate of the cleaning agent at the nozzle outlet, which can effectively adapt to the concave and convex surfaces of bushings and insulators of different sizes; 3. Most of the operations of this application (such as the number of cleaning cycles in one circle, the lifting and lowering of the cleaning part) can be set in advance or performed through the controller in the middle, which greatly saves manpower compared to wiping with a rag or a handheld electric tool.

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Reference Figure 1-Figure 4 The embodiment of the present application discloses an electric tool for cleaning the surface of a bushing and an insulator, which includes a bracket 1, a cleaning module and a cleaning agent pumping module. The bracket 1 is used to provide support, height adjustment and walking functions.

[0023] The cleaning module includes: The cleaning seat 2 is mounted on the bracket 1, and has an arc-shaped notch 21 at one end thereof facing away from the bracket 1; The full circle gear 31 is rotatably mounted on the cleaning seat 2; The gear motor 32 is mounted on the cleaning seat 2 and is used to drive the full circle gear 31 to rotate forward and reverse; The half-circle gear ring 4 is rotatably mounted on the cleaning seat 2 with its axis as the rotation axis, and the outer arc teeth of the half-circle gear ring 4 are meshed and connected with the full-circle gear 31. The half-circle gear ring 4 is arranged at the arc-shaped notch 21 of the cleaning seat 2 and is coaxially arranged therewith; The hydraulic telescopic system 7 is provided with two and is respectively installed at the two ends of the inner arc side of the half-circle gear ring 4; The brush plate 5 is rotatably mounted on the telescopic output end of the hydraulic telescopic system 7; and The nozzle 6 is arranged on the half-circle gear ring 4 and points to the area between the two brush discs 5; The cleaning agent pumping module is used to pump cleaning agent to the nozzle 6 .

[0024] During operation, the bracket 1 is transferred to the bottom of the bushing or insulator to be cleaned, and the cleaning seat 2 is moved to the bushing or insulator over the two brush discs 5 and located in the arc-shaped notch 21 of the cleaning seat 2; then, the cleaning agent is pumped to the nozzle 6 through the cleaning agent pumping module, and the gear motor 32 drives the full circle gear 31 to rotate, thereby driving the half circle gear ring 4 to rotate; when the full circle gear 31 rotates clockwise, the half circle gear ring 4 rotates counterclockwise, driving the hydraulic telescopic system 7 and the brush disc 5 at both ends of the half circle gear ring 4 to make circular motion; when the half circle gear ring 4 rotates counterclockwise to the end, the two brush discs 5 have completed the cleaning of 3 / 4 of the surface. Then, the gear motor 32 is changed to counterclockwise rotation, and the half circle gear ring 4 rotates clockwise accordingly; when the half circle gear ring 4 rotates clockwise to the end, the two electric brush discs 5 have just completed a full circle of surface cleaning. This cycle is repeated until it is cleaned. The number of cycles can be set in advance or adjusted midway according to the actual cleaning situation. Therefore, when cleaning the bushings and insulators, workers do not have to climb to carry out the cleaning work, which improves work efficiency and reduces the risk of falling from heights.

[0025] In addition, refer to Figure 2-Figure 3 An interconnecting pipeline 41 is provided on the half-ring gear 4 , the outlet of the interconnecting pipeline 41 is connected to the nozzle 6 and the liquid supply end of the hydraulic telescopic system 7 , and the cleaning agent pumping module is used to pump cleaning agent into the interconnecting pipeline 41 .

[0026] The hydraulic telescopic system 7 comprises: A fixed cylinder 71 is fixedly connected to the end of the inner arc side of the half-circle gear ring 4; The movable rod 72 is anti-slip and slidably arranged in the fixed cylinder 71, and the brush plate 5 is rotatably mounted on the free end of the movable rod 72; The hydraulic chamber 711 is located in the fixed cylinder 71 and on the side of the movable rod 72 close to the half-circle gear ring 4, and is connected to the interconnecting pipeline 41; The damping spring 73 is disposed in the fixed cylinder 71 and sleeved on the outer circumference of the movable rod 72 ; when the cleaning agent is pumped into the hydraulic chamber 711 , the damping spring 73 is compressed and deformed.

[0027] In this way, when the cleaning agent pumping module is not working, no high-pressure cleaning agent is introduced into the interconnecting pipeline 41. At this time, the movable rod 72 retracts to a position close to the half-circle gear ring 4 under the action of the damping spring 73, so that the two brush discs 5 are separated to the maximum distance, which can facilitate the insertion of the sleeve or insulator into the arc-shaped notch 21 of the cleaning seat 2; and when the cleaning agent pumping module is started, the cleaning agent is pumped into the interconnecting pipeline, and a part of the cleaning agent is sprayed from the nozzle 6 to rinse the outer wall of the sleeve or insulator, and the other part of the cleaning agent flows to the two ends of the interconnecting pipeline and flows to the two hydraulic chambers 711 of the two fixed cylinders 71 respectively. As the cleaning agent pumping flow rate of the cleaning agent increases, the volume of the cleaning agent entering the hydraulic chamber 711 increases, which can push the movable rod 72 to move in the fixed cylinder 71 in the direction away from the half-circle gear ring 4, thereby making the two brush discs 5 approach each other to approach the small-sized sleeve or insulator.

[0028] Therefore, by controlling the flow rate of the cleaning agent pumping module, not only the flow rate of the cleaning agent sprayed out of the nozzle 6 can be controlled, but also the length of the movable rod 72 extending in the fixed cylinder 71 can be controlled, that is, the spacing between the two brush discs 5 can be achieved by changing the cleaning agent flow rate in the interconnecting pipeline 41, which can facilitate continuous cleaning of sleeves and insulators of different sizes; and because the extension of the movable rod 72 in the fixed cylinder 71 is achieved by remembering the pressure of the cleaning agent in the hydraulic chamber 711, that is, the brush disc 5 is in a flexible and tight state on the outer wall of the sleeve or the insulator, and can be adaptively adjusted according to the actual shape of the sleeve and the insulator, which can effectively avoid the occurrence of jamming after the gap between the two brush discs 5 is adjusted.

[0029] In order to further improve the scrubbing effect of the brush plate 5.

[0030] In one embodiment, referring to Figure 4 and Figure 5 A cleaning motor 51 is installed at the free end of the movable rod 72, and a brush disc 5 is installed at the output end of the cleaning motor 51; the speed of the brush disc 5 can be controlled by the cleaning motor 51, so that the brush disc 5 can rotate autonomously and clean the outer wall of the bushing or the insulator.

[0031] In another embodiment, a hydraulic blade (not shown in the figure) is rotatably mounted on the free end of the movable rod 72, the brush plate 5 is coaxially fixed to the hydraulic blade, and an impact nozzle connected to the interconnecting pipeline 41 and pointing to the hydraulic blade is provided on the inner arc side of the half-circle gear ring 4. Therefore, when the cleaning agent is pumped into the interconnecting pipeline 41, a part of the cleaning agent can be sprayed out from the impact nozzle and impact on the blade of the hydraulic blade, and the hydraulic blade and the brush plate 5 thereon can also be driven to rotate, and the autonomous rotation and washing effect of the brush plate 5 can also be achieved; and the impact nozzle can also increase the diffusion area of ​​the cleaning agent after the cleaning agent splashes on the hydraulic blade, thereby improving the cleaning efficiency of the cleaning agent on the bushing or insulator.

[0032] In addition, refer to Figure 1 and Figure 2 , the cleaning agent pumping module includes: A cleaning agent tank 81 is mounted on the bracket 1; A hose 82, one end of which is connected to the interconnecting pipeline 41 on the half-circle gear ring 4; The pressure pump 83 is used to pump the cleaning agent in the cleaning agent tank 81 into the hose 82 . Specifically, a base frame 84 is installed on the bracket 1 , and the cleaning agent tank 81 and the pressure pump 83 are both installed on the base frame 84 .

[0033] The cleaning seat 2 is provided with a distance measuring member 9 for detecting the distance value between the cleaning workpiece and the cleaning workpiece. The distance measuring member 9 is connected to a controller, and the controller is connected to a pressure pump 83. The distance measuring member 9 can be a camera or an infrared rangefinder, a laser rangefinder, etc. The controller is configured to control the pressurizing pump 83 to increase the flow rate of the output cleaning agent when the distance measuring element 9 detects that the distance value increases; and to control the pressurizing pump 83 to reduce the flow rate of the output cleaning agent when the distance measuring element 9 detects that the distance value decreases.

[0034] Therefore, by measuring the distance value between the distance measuring part 9 and the workpiece to be cleaned, the diameter of the part to be cleaned can be determined. For example, if the measured distance value is larger, it means that the part to be cleaned is farther from the nozzle 6, and the corresponding cross-sectional diameter of the part to be cleaned is smaller; in order to achieve the cleaning effect, it is necessary to increase the flow rate of the cleaning agent at the outlet of the nozzle 6 and increase the hydraulic pressure of the hydraulic telescopic system 7, thereby reducing the distance between the two brush discs 5. If the measured distance value is smaller, it means that the part to be cleaned is closer to the nozzle 6, and the corresponding cross-sectional diameter of the part to be cleaned is larger; at this time, the flow rate of the cleaning agent at the outlet of the nozzle 6 can be appropriately reduced, and the hydraulic pressure of the hydraulic telescopic system 7 can be reduced. After the cleaning agent pressure in the hydraulic chamber 711 is reduced, the movable rod 72 can retreat under the deformation force of the damping spring 73, thereby appropriately increasing the distance between the two brush discs 5. In this way, the effect of automatically adjusting the distance between the two brush discs 5 can be achieved, without the need for manual adjustment by the operator, and the degree of automation is higher.

[0035] Furthermore, the support 1 comprises: A base 11 having rollers thereon; The lifting rod 12 is installed on the base 11, and the cleaning seat 2 is installed on the top of the lifting rod 12. The lifting rod 12 can be a multi-section telescopic support, and the total length of the multi-section telescopic sections can be adjusted and locked; a pitch adjustment mechanism 13 is arranged between the cleaning seat 2 and the top of the lifting rod 12. The pitch adjustment mechanism 13 can specifically be a bolt and nut structure, and the cleaning seat 2 is hinged at the top of the lifting rod 12 by bolts, and after the pitch angle adjustment of the cleaning seat 2 is completed, the nut is tightened to complete the locking of the cleaning seat 2.

[0036] The implementation principle of an electric tool for cleaning the surface of a bushing and an insulator in the embodiment of the present application is as follows: During operation, the bracket 1 is transferred to the bottom of the bushing or insulator to be cleaned, and the cleaning seat 2 is moved to the bushing or insulator over the two brush discs 5 and located in the arc-shaped notch 21 of the cleaning seat 2; then, the cleaning agent is pumped to the nozzle 6 through the cleaning agent pumping module, and the gear motor 32 drives the full circle gear 31 to rotate, thereby driving the half circle gear ring 4 to rotate; when the full circle gear 31 rotates clockwise, the half circle gear ring 4 rotates counterclockwise, driving the hydraulic telescopic system 7 and the brush disc 5 at both ends of the half circle gear ring 4 to make circular motion; when the half circle gear ring 4 rotates counterclockwise to the end, the two brush discs 5 have completed the cleaning of 3 / 4 of the surface. Then, the gear motor 32 is changed to counterclockwise rotation, and the half circle gear ring 4 rotates clockwise accordingly; when the half circle gear ring 4 rotates clockwise to the end, the two electric brush discs 5 have just completed a full circle of surface cleaning. This cycle is repeated until it is cleaned. The number of cycles can be set in advance or adjusted midway according to the actual cleaning situation. Therefore, when cleaning the bushings and insulators, workers do not have to climb to carry out the cleaning work, which improves work efficiency and reduces the risk of falling from heights.
