Description

Technical Field

[0001] The invention relates to the field of power device maintenance, in particular to an insulator cleaning device. Background Art

[0002] In the power system, insulators are exposed to the outdoor environment for a long time, affected by wind, sand, rain, dust, etc., and dirt easily accumulates on the surface. The accumulation of these dirt will lead to the degradation of insulation performance. Especially in a humid environment, the dirty layer may become a conductor for arc discharge, increase the risk of leakage, and even cause a short circuit accident in severe cases. Therefore, regular cleaning of insulators in the power system has become one of the key measures to ensure the safe operation of the power grid.

[0003] As for the current power insulators, cleaning is the way to ensure long-term operation when the power is cut off. However, the traditional method of cleaning the insulators on the surface of the cable is basically done manually. The traditional manual cleaning process has low efficiency, high labor costs, difficulty in operation at high altitudes and complex terrains, and high safety risks. However, manual operation is characterized by careful and clean cleaning. Some current mechanical cleaning methods are not thorough, especially for the wavy structure at the bottom of the insulator. It is often difficult to fully clean the gaps, affecting the overall performance.

[0004] At present, traditional insulator cleaning mainly relies on manual or simple mechanical means, but these methods usually have problems such as incomplete cleaning effect, low efficiency, and high labor costs. Manual cleaning is not only time-consuming and labor-intensive, but also difficult to operate at high altitudes and in complex terrains, and there are high safety risks. Common mechanical cleaning devices are difficult to achieve multi-directional and multi-angle cleaning due to their simple structure, especially the dirt on the side walls and gaps of the insulator is difficult to remove, resulting in unsatisfactory cleaning results.

[0005] In response to the above problems, the art urgently needs a device that can perform comprehensive and efficient cleaning on the surface of insulators, which can not only cover the cleaning needs of the upper and lower sides and side walls of the insulators, but also has strong stability and adaptability to improve the cleaning efficiency and ensure that the surface of the insulator remains in a good insulation state, thereby improving the safety and operational reliability of the power grid.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0021] At present, there are several major problems in the field of insulator cleaning: First, the surface of the insulator is exposed to the outdoor environment all year round, which is prone to the accumulation of dust, dirt and moisture, resulting in a decrease in insulation performance, which in turn affects the stability and safety of the power system; second, traditional cleaning methods mostly rely on manual operation or simple mechanical scrubbing, which is not only inefficient but also difficult to achieve comprehensive cleaning, especially for the dirt in the gaps on the surface of the insulator; third, the cleaning device lacks adaptability when facing different installation angles and external environments, and is prone to cleaning dead corners. In addition, manual cleaning is usually accompanied by high-altitude operations, which poses a major safety hazard, and the strength and cleaning range of simple mechanical cleaning are also difficult to accurately control, which may cause secondary damage to the surface of the insulator.

[0022] The design of this solution, through the cooperation of the cleaning unit and the driving unit 10, can stably adhere to the surface of the insulator at different inclination angles to achieve automated and all-round cleaning, effectively solving the problems of low efficiency, incomplete cleaning and poor adaptability in traditional methods, and providing a more reliable insulator maintenance method for the power system, including the following specific technical details.

[0023] like Figure 1-Figure 14 As shown, the present invention provides: an insulator cleaning device, including an insulator body 70, and also includes: Two groups of cleaning units are arranged around the insulator body 70 in a circular motion, including a transverse cleaning unit 30 and a lateral cleaning unit 40 for cleaning the surface of the insulator body 70. The transverse cleaning unit 30 is attached to one end of the insulator body 70 and rotates, vibrating and blowing out airflow at the same time; the cleaning unit is responsible for all-round cleaning of the surface of the insulator body 70, and it includes a transverse cleaning unit 30 and a lateral cleaning unit 40, which are respectively used for cleaning the upper and lower sides and side walls of the insulator body 70. During the cleaning process, the transverse cleaning unit 30 can not only move around the surface of the insulator body 70, but also effectively clean the dirt on the surface and gaps of the insulator body 70 through the high-frequency vibration generated by the airflow, thereby improving the depth and effect of cleaning. In addition, the lateral cleaning unit 40 will also rotate during the revolution of the device to ensure that the dirt on the side wall of the insulator body 70 is fully cleaned.

[0024] Specifically, Fig. 9As shown: the transverse cleaning unit 30 includes an axle seat 31 fixedly connected to the surface of the arc-shaped slide 16, a rotating cylinder 32 is rotatably installed on the surface of the axle seat 31, a first planetary gear 33 which is transmission-coordinated with the meshing assembly 50 is fixedly connected to the surface of the rotating cylinder 32, a wind wheel 38 is fixedly connected to one end of the rotating cylinder 32, a hose 34 is connected to the other end of the rotating cylinder 32, a transverse brush 37 is fixedly connected to the other end of the hose 34, the transverse brush 37 is hollow and a conical block 35 is provided at the portion connected to the hose 34 to protect it, a support spring 36 is fixedly connected to the opposite surface of the conical block 35 and the rotating cylinder 32, the support spring 36 is spirally coiled and located on the surface of the hose 34, a diaphragm 39 is provided on the inner wall of one end of the transverse brush 37.

[0025] When the transverse cleaning unit 30 is in operation, the first planetary gear 33 meshes with the first arc-shaped rack 51 and the second arc-shaped rack 52 to rotate, and the rotating cylinder 32 rotates. As the first wind wheel 38 rotates at a high speed, the airflow is pressurized, and the compressed airflow is introduced into the transverse brush 37 through the hose 34, so that the diaphragm 39 vibrates at one end of the transverse brush 37, so that the vibration coordination of the cleaning process is realized, and the airflow can blow out the dust. Through the coordination of airflow and vibration, not only can the surface dust be removed efficiently, but also the dirt can be prevented from being deposited on the insulator itself. The surface of the insulator body 70 accumulates again, thereby effectively maintaining the clean state of the insulator body 70, and as the whole moves, the lateral cleaning unit 30 cleans the surface of the insulator body 70 with slow movement. At the same time, the insulator body 70 blocks the lateral cleaning unit 30. When the conical block 35 of the cleaning unit contacts the insulator body 70, the conical block 35 fits against the side edge of the insulator body 70 and supports the spring 36 to bend under pressure, thereby realizing the bending of the lateral brush 37 and crossing the insulator body 70 to perform step-by-step cleaning operations.

[0026] Specifically, Figure 5 As shown: the lateral cleaning unit 40 includes an axis frame 41 fixedly connected to the surface of the arc-shaped slide 16, a vertical brush 42 is rotatably installed on the surface of the axis frame 41, and the bottom end of the vertical brush 42 is fixedly connected to a second planetary gear 43 that meshes with the meshing assembly 50.

[0027] By providing the lateral cleaning unit 40 , the vertical brush 42 can cooperate with the transverse brush 37 to clean the side edge of the insulator, and the blind area of ​​the transverse brush 37 can be further cleaned.

[0028] The insulator body 70 of the driving unit 10 axially penetrates the driving unit 10, driving the two groups of cleaning units to move alternately on the surface of the insulator body 70, and the surface of the driving unit 10 is provided with a meshing assembly 50; Specifically, Figure 7As shown: the driving unit 10 includes an arc-shaped slide rail 11, a driver 12 is fixedly connected to the surface of the arc-shaped slide rail 11, an output shaft of the driver 12 is fixedly connected to a driving gear 13, two driven gears 14 are meshed on the surface of the driving gear 13, and the two driven gears 14 are meshed with a transmission wheel set 15, and the transmission wheel set 15 and the driven gear 14 are both rotatably mounted on one side of the arc-shaped slide rail 11, and two arc-shaped slides 16 are limitedly slid on the inner wall of the arc-shaped slide rail 11, and the two transmission wheel sets 15 are meshed and transmitted on the side walls of the two arc-shaped slides 16.

[0029] The arc-shaped slide 16 of the driving unit 10 and the arc-shaped slide rail 11 cooperate and slide with each other. The transmission wheel group 15 on one side of the arc-shaped slide rail 11 passes through the arc-shaped slide rail 11 and drives the arc-shaped slide 16 to move. When the arc-shaped slide 16 moves, it slides on the inner wall of the arc-shaped slide rail 11. When the arc-shaped slide 16 disengages from one of its transmission wheel groups 15, the other transmission wheel group 15 maintains transmission with the arc-shaped slide 16, so that the arc-shaped slide 16 can maintain continuous rotation around the insulator body 70.

[0030] Specifically, Figure 8 As shown: the transmission wheel group 15 includes two transmission gears 151 meshing with the side walls of the arc-shaped slide 16 for transmission, and the opposite ends of the two transmission gears 151 are fixedly connected with side umbrella wheels 152 that rotate coaxially therewith, and the surfaces of the two side umbrella wheels 152 are commonly meshed with synchronous umbrella wheels 153, and the synchronous umbrella wheels 153 are rotatably installed on the surface of the arc-shaped slide rail 11.

[0031] By setting the transmission wheel set 15, the two transmission gears 151 of the transmission wheel set 15 are meshed with the two side bevel wheels 152 and the synchronous bevel wheel 153, so that the two transmission gears 151 present opposite rotation directions, thereby driving the two arc-shaped slides 16 to move in opposite directions.

[0032] Specifically, Figure 6 As shown: the meshing assembly 50 includes a first arc-shaped rack 51 symmetrically fixed on both sides of the arc-shaped slide rail 11, a second arc-shaped rack 52 is fitted on one side of the first arc-shaped rack 51, and the second arc-shaped rack 52 is installed on the surface of the arc-shaped slide rail 11 by screws. The first arc-shaped rack 51 and the second arc-shaped rack 52 form a continuous closed circle, and the opposite surfaces of the two second arc-shaped racks 52 are fixedly connected with a connecting plate 53 for installing the corresponding positioning assembly 60.

[0033] The first arc-shaped rack 51 and the second arc-shaped rack 52 of the meshing assembly 50 can cooperate to form a ring to maintain continuous meshing with the cleaning unit. At the same time, the second arc-shaped rack 52 can be quickly installed by screws, which is convenient for installation and cooperation on the surface of the insulator body 70.

[0034] The two groups of displacement components 20 are movably connected to the inner wall of the driving unit 10, and the two groups of displacement components 20 are in a staggered motion state with each other, and at least one group of the two groups of displacement components 20 is in contact with the surface of the insulator body 70; Specifically, Fig.12 As shown: the displacement assembly 20 includes an arc plate 21 movably connected to the inner wall of the arc slide 16 through a pin shaft, the other end of the arc plate 21 is movably connected to a wheel frame 22 through a pin shaft, a rubber wheel 24 is installed on the surface of the wheel frame 22, and adjustment screws 23 are provided on the surfaces of the arc plate 21 and the wheel frame 22, and the opposite surfaces of the arc plate 21 and the arc slide rail 11 are fixedly connected with a compression spring 25.

[0035] By setting the arc plate 21, one end of the arc plate 21 keeps the wheel frame 22 tilted through a pin shaft, and at the same time, the arc plate 21 can move under the action of the compression spring 25 through the pin shaft at the other end, so as to provide the rubber wheel 24 with a buffer when subjected to a large force and provide sufficient fitting force. The wheel frame 22 is in a tilted state, so that after it detaches from the edge of the insulator body 70, it can still move to the edge of another insulator body 70 during the rolling process.

[0036] A plurality of positioning components 60 are evenly distributed on the surfaces of the driving unit 10 and the engaging component 50, and are used to clamp each other and fit on the surface of the insulator body 70 for movement, and to position the insulator body 70 at the axial position of the driving unit 10; Specifically, Fig.11 As shown: the positioning assembly 60 includes a positioning frame 61 fixedly connected to the side wall of the arc-shaped slide rail 11, the inner wall of the positioning frame 61 is movably connected to a swing arm 62 and a horizontal retaining frame 64 through a pin shaft, the top ends of the swing arm 62 and the horizontal retaining frame 64 are movably connected to a track 63 through a pin shaft, and a positioning spring 65 is installed in the positioning frame 61 and the swing arm 62.

[0037] By setting a positioning component 60, the positioning component 60 has a swing arm 62 and a horizontal retaining frame 64 to support the track 63. When the track 63 moves to different positions, it can always remain horizontal on the surface of the insulator body 70 to prevent it from being stuck in the gap between the insulator bodies 70. The spacing between the insulator bodies 70 under different specifications is different, and the length of the track 63 is constant. If the track 63 can move or tilt, it is very easy to get stuck in the gap. The horizontal retaining frame 64 cooperates with the swing arm 62 to keep the track 63 always in contact with the surface of the insulator body 70 while maintaining a stable horizontal state, and is not affected by changes in the contact state, thereby ensuring stable clamping and movement.

[0038] During cleaning, the two groups of cleaning units move alternately. The transverse cleaning unit 30 cleans the upper and lower sides of the insulator body 70, and the lateral cleaning unit 40 cleans the side wall of the insulator body 70. The transverse cleaning unit 30 blows out a cleaning airflow to the adjacent transverse cleaning unit 30 through the airflow. The airflow cleaning simultaneously causes high-frequency vibration at one end of the transverse cleaning unit 30.

[0039] Specifically, Figure 7 As shown, the arc-shaped slide rail 11 and the arc-shaped slide 16 are both arranged in a C shape, and the two arc-shaped slides 16 are located on the inner wall of the arc-shaped slide rail 11 and mesh with at least one set of transmission wheel sets 15 for transmission.

[0040] The arc-shaped slide 16 and the arc-shaped slide rail 11 are arranged in a C shape so as to be able to perform continuous meshing transmission in coordination with the motion trajectory of the cleaning unit.

[0041] When the present solution is used, the two positioning components 60 on the surface of the driving unit 10 are attached to the surface of the insulator body 70 in a vertical or inclined state, and the two second arc-shaped racks 52 of the meshing component 50 are attached to one side of the two first arc-shaped racks 51, and the second arc-shaped racks 52 are fixed to the surface of the arc-shaped slide rail 11 by screws. At this time, the positioning components 60 on the surface of the two arc-shaped racks cooperate with the two positioning components 60 on the surface of the arc-shaped slide rail 11 to clamp the insulator body 70, and the positioning spring 65 in the positioning component 60 keeps the crawler 63 pressed and keeps elastically supporting the driving unit 10; Then the driver 12 is started, and the driver 12 rotates with the two driven gears 14 through the driving gear 13. The two driven gears 14 respectively rotate with the two transmission wheel sets 15. When the two transmission wheel sets 15 rotate, they engage with the two arc-shaped slides 16 to rotate in opposite directions on the inner wall of the arc-shaped slide rail 11. When the two arc-shaped slides 16 rotate around the surface of the insulator body 70 in opposite directions, the transverse cleaning units 30 and the lateral cleaning units 40 on the surface of the arc-shaped slides 16 move accordingly and revolve around the insulator body 70; The lateral cleaning unit 30 revolves around the insulator body 70, and the first planetary gear 33 of the lateral cleaning unit 30 meshes with the surface of the meshing assembly 50. The meshing assembly 50 is fixed on the surface of the arc-shaped slide rail 11, so that the lateral cleaning unit 30 in the moving process starts to rotate with the cooperation of the meshing assembly 50, wherein the first planetary gear 33 drives the rotating cylinder 32 to rotate on the inner wall of the shaft seat 31, and at the same time, one end of the rotating cylinder 32 drives the lateral brush 37 to rotate through the supporting spring 36, and at the same time, the wind wheel 38 compresses and draws in the airflow during the self-rotation process, and the airflow enters the lateral brush 37 through the hose 34, and then the lateral brush The brush 37 sprays airflow when it is rotating and cleaning, and the airflow can blow away the cleaned dust to prevent accumulation. When the airflow blows through the diaphragm 39, the diaphragm 39 is vibrated at a high frequency under the action of the airflow. The diaphragm 39 vibrates as a whole at the end of the transverse brush 37, so that it vibrates in coordination with the cleaning process, improving the cleaning efficiency and having a better cleaning effect on the gap. When the transverse brush 37 is attached to the insulator body 70, the support spring 36 will be slightly bent under the action of friction, so that the transverse brush 37 is tilted to point to the transverse brush 37 of another transverse cleaning unit 30, and clean it through the airflow; When the side cleaning unit 40 moves, it is meshed with the surface of the meshing assembly 50 through the second planetary gear 43, and then it rotates while revolving and continuously cleans the side edge of the insulator body 70; The cleaning unit is used to carry out targeted cleaning of the upper and lower sides of the insulator body 70 except the sides. At the same time, a cleaning method combining airflow and vibration is adopted to fully clean the bottom gap. The circular design of the insulator body 70 can match the axial position during the revolution, and the top or bottom can be brushed and cleaned during the rotation. The cleaned dust can be quickly blown away by the airflow to avoid accumulation. Two sets of cleaning units realize secondary cleaning after pre-cleaning, and the cleaning rotation directions of the pre-cleaning and secondary cleaning are opposite, which further improves the effect of cleaning dirt in dead corners.

[0042] Before installation, by rotating the adjusting screw 23 of the displacement assembly 20, the adjusting screw 23 brings the wheel frame 22 to tilt at one end of the arc plate 21 through the pin shaft, and by adjusting the inclination angle of the wheel frame 22, the rubber wheel 24 on the surface of the wheel frame 22 can be moved at a certain angle. When the cleaning process needs to move, as the two arc-shaped slides 16 rotate in opposite directions, the displacement assembly 20 of the inner wall moves synchronously, and the arc plate 21 moves through the pin shaft at one end under the action of the compression spring 25, and presses the rubber wheel 24 on the surface of the insulator body 70, and the rubber wheels 24 of the two sets of staggered displacement assemblies 20 fit together. When moving along the side wall of the insulator body 70, the rubber wheel 24 is at a certain inclination angle, so that it moves by fitting on the surface of the insulator body 70 under the action of friction, and at least one group of two displacement components 20 fits on the surface of the corresponding insulator body 70, so that it can continuously provide a displacement force, and the displacement force can be combined with the track 63 of the positioning component 60 to move. By adjusting the screw 23 to control the inclination angle of the wheel frame 22, the ratio of the cleaning force to the moving speed of the driver 12 at different rotation speeds can be controlled. The larger the inclination angle, the greater the movement amplitude at the same rotation speed and cleaning force.

[0043] This solution uses a set of automated cleaning devices to achieve efficient cleaning of the surface of the insulator body 70. The device adopts a design that combines the transverse and lateral cleaning units 40, which can clean the upper and lower sides and side walls of the insulator body 70 at the same time. The drive system enables the cleaning unit to revolve and rotate around the insulator body 70. Through precise meshing and spring support, the transverse brush 37 generates high-frequency vibration and sprays compressed air during cleaning, effectively removing dust and preventing it from accumulating again. Combined with the dual cleaning auxiliary mode, namely airflow and vibration, the airflow can perform airflow impact cleaning on the other transverse brush 37 at its tilt angle during the cleaning process of the transverse brush 37, and can cooperate with the transverse brush 37 to deeply clean the gap, with significant cleaning effect. The overall structure is flexible and adapts to vertically or tilted installation of the insulator body 70, greatly reducing the cost of manual maintenance.
