Description

Technical Field

[0001] The invention belongs to the technical field of cleaning of electric power equipment, and is particularly suitable for cleaning insulator strings and post insulators in the electric power industry, and specifically relates to an automatic insulator cleaning device. Background Art

[0002] Insulators are divided into insulator strings and post insulators. They are widely used in the power industry. Insulators themselves are insulating components. They provide insulation support for high-voltage equipment and also provide insulation and fixing support for high-voltage lines. Insulators are widely used in the insulation and fixing of overhead transmission lines and outdoor lead-in wires of substations. Insulators ensure the insulation of live equipment and live materials to the ground, and ensure the stable operation of the power system. Since most insulators are arranged outdoors, long-term exposure to wind and rain will cause the surface of the insulator to be covered with dust and other dirt. These dirt are often not good insulators, which reduces the insulation capacity of the insulator and causes accidents such as flashover discharge.

[0003] In order to prevent such accidents, the power regulations require that insulators be cleaned regularly (generally once a year, and the frequency of cleaning should be increased in areas with serious pollution). Insulator cleaning is generally divided into live cleaning and power-off cleaning. Live cleaning is further divided into live sweeping and live washing. Live sweeping is generally carried out by a group of four people, using extended electric brushes and insulating support rods to clean the insulators. This method first requires a large number of people to cooperate with the operation, which is very labor-intensive; secondly, this method has the disadvantage of not cleaning the dead corners that people cannot see; finally, this method is relatively dangerous. The insulators of overhead lines are often very high, and people are prone to danger during climbing and operation. At the same time, concentrated cleaning will generate a lot of dust, which is prone to flashover discharge and injury. Live washing generally uses special insulating liquid for flushing. The flushing process also has the problems of inadequate cleaning, time-consuming and labor-intensive, and easy to cause discharge hazards. The power-off cleaning of insulators requires the entire line or substation to be shut down, which has a huge impact on people's electricity use and causes immeasurable economic losses.

[0004] In summary, the current cleaning of insulators, no matter which cleaning method is used, requires a lot of manpower, and there are dangers and disadvantages. The cleaning of insulators is time-consuming, labor-intensive, costly and dangerous. Summary of the invention

[0017] Beneficial effects:

[0018] 1. The invention has strong versatility and is not picky about insulators. One of the innovations of the invention is the long-stroke flexible suspension system, which uses multiple long-stroke suspensions equipped with track wheels to simulate the multi-link independent suspension of a car, and surrounds the insulators evenly at 360° without dead angles, making it difficult to fall off.

DETAILED DESCRIPTION

[0041] The following will be combined with the accompanying drawings of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] like Figure 1 and Figure 2As shown in FIG. 1 , the main body of the device of the present invention is a cylindrical structured cylinder 1, which is the foundation of the device. Other components are connected to the cylinder 1 by direct or indirect connection. The outside of the cylinder 1 is connected to the wind collection ring 2 through a plurality of receiving gears 5. The structure of the wind collection ring 2 is shown in FIG. Figure 7-8 As shown, it includes a second inner gear ring 2-1, which is rotatably mounted on the outside of the cylinder 1, and the teeth of the second inner gear ring 2-1 are meshed with the receiving gear 5 on the cylinder 1. A plurality of wind collection bowls 2-2 are arranged at intervals around the outer circumference of the second inner gear ring 2-1. The wind collection bowl 2-2 is a bowl-shaped component that can and can only rotate in one direction under the action of wind. The receiving gear 5, on the one hand, realizes the auxiliary assembly of the wind collection ring 2 and the cylinder 1, and on the other hand, transmits the wind energy collected by the wind collection ring 2 to the power distributor 6 through one of the receiving gears 5, thereby realizing the power input of the equipment.

[0043] Install the following on the inner side of the cylinder 1: Figure 3 The power distributor 6 shown in the figure includes components such as a bilateral output reduction gear set 6-1, a reversing frame 6-2, and a bilateral transmission differential 6-3. The power collected by the wind power collection ring 2 can be decelerated, torque increased, and reciprocated, and the power can be transmitted to the cleaning mechanism 3 and the walking mechanism 4 respectively. There are two groups of cleaning mechanisms 3, one group of cleaning mechanisms 3 is set at each end of the cylinder 1. Under the action of the power distributor 6, the two groups of cleaning mechanisms 3 can each rotate around the central axis of the cylinder 1 to clean the insulator. Under the transmission action of the bilateral output reduction gear set 6-1, the two groups of cleaning mechanisms rotate in opposite directions, which can offset the deflection force generated by the rotation.

[0044] like Fig.15 As shown, the cleaning mechanism 3 includes a cleaning ring 3-2, and a circle of cleaning brushes 3-1 facing the center of the barrel 1 (i.e., the direction of the insulator) is installed on the inner side of the cleaning ring 3-2. As the cleaning ring 3-2 rotates (cooperating with the up and down movement of the walking mechanism 4, the comprehensive movement is a spiral rotation along the extension direction of the insulator), the cleaning brush 3-1 cleans the surface of the insulator. Multiple cleaning brushes 3-1 face the center of the barrel 1 at multiple angles, and rotate spirally around the insulator driven by the rotation of the cleaning ring 3-2, so as to clean the dirt in the groove of the insulator umbrella.

[0045] The walking mechanism 4 is a device in the form of a multi-link track wheel. Fig.13As shown, the walking mechanism includes a crawler track 4-5, whose structure is similar to that of a tank track and has strong passability. The crawler track 4-5 carries several transmission wheels inside to realize the chain transmission of the crawler track 4-5. One of the transmission wheels is connected to the bilateral transmission differential 6-3 of the power distributor 6 through a flexible shaft (the flexible shaft transmits torque through a flexible shaft, which is often used in hanging mills. The flexible shaft realizes power transmission at any angle and any distance) to obtain power from the power distributor. The crawler track 4-5 of the walking mechanism is pressed tightly against the outer surface of the insulator umbrella skirt and is firmly articulated with the cylinder 1 through the large-stroke suspension system composed of the walking mechanism 4.

[0046] The device is also provided with Figure 4 and Figure 5 The reversing mechanism shown in the figure includes a reversing baffle ring 7, a rigid rod 8, a reversing frame 6-2 and a floating reversing gear 6-5. A reversing baffle ring 7 is provided at both ends of the cylinder 1 and on the outside of each group of cleaning mechanisms 3. The upper and lower groups of reversing baffle rings 7 are connected to each other through the rigid rod 8 that penetrates the cylinder 1 to form a rigid frame. The rigid frame can move up and down a certain distance. During the movement of the equipment, when the reversing baffle ring 7 hits the wire or other objects at the end of the insulator, the reversing baffle ring 7 will move to the other direction relative to the cylinder 1. The rigid rod 8 is connected to the reversing frame 6-2 and is provided with Fig.12 The automatic return mechanism of the commutator shown ensures that power can be transmitted well, and there will be no "neutral" powerless situation or gear jamming, so that the device changes its direction of travel when it reaches the end of the insulator to achieve reciprocating motion.

[0047] The following is a detailed introduction to the structure and function of each part:

[0048] like Figure 6As shown, the cylinder 1 is a cylindrical plate-shell structure, and other components are arranged on the shell of the cylinder 1. An array of articulated seats of the traveling mechanism 4 is installed in the middle of the inner wall of the cylinder 1, which is used to hinge and support the traveling mechanism 4. Generally speaking, the number of articulated seats of the traveling mechanism 4 needs to be evenly arranged in three groups or more along the circumference of the cylinder 1 according to the size of the insulator. The thicker the insulator, the more traveling mechanisms 4 and articulated seats need to be installed. Each group of articulated seats of the traveling mechanism 4 includes two upper and lower swing arm articulated seats 13 and a fork arm articulated seat 14 located between the two swing arm articulated seats 13. The swing arm articulated seat 13 is directly connected to the inner wall of the cylinder 1, and is used to hinge the two arc-shaped swing arms 15 connected on the upper and lower sides of the traveling mechanism 4. The fork arm articulated seat 14 includes two groups of triangular flat plates arranged parallel to each other, one side of the triangular flat plate is connected to the inner wall of the cylinder 1, and a fork arm hinge fulcrum is set at the left end of the triangular flat plate, which is used to hinge the V-shaped fork arm 16 in the middle part of the traveling mechanism 4. The receiving gear 5 is rotatably installed between the two triangular plates. A plurality of square through holes that are transparent inside and outside are evenly arranged on the side wall of the cylinder 1 along the circumference of the cylinder 1. A part of the receiving gear 5 extends from the square through hole to the outside of the cylinder 1, and meshes with the second inner gear ring 2-1 on the wind collection ring 2 to receive and transmit the power from the wind collection ring 2. Because the receiving gear 5 is installed on the fork arm hinge seat 14 in the walking mechanism 4, the number of the receiving gear 5 is consistent with the number of the walking mechanism 4. According to the diameter of the insulator, three or more receiving gears 5 can be set to achieve good action.

[0049] The inner side of the cylinder 1 is provided with vertical reinforcing ribs, which are connected to the cylindrical cylinder shell and pass through the hinge seat of the walking mechanism 4 from top to bottom. Fig.15 The supporting ring 17 of the cleaning ring 3-2 shown plays the role of strengthening the structure, focusing on strengthening the hinge points of the walking mechanism 4 and the shaft joints of the receiving gear 5, making them less likely to deform and making the entire mechanism more stable.

[0050] There are two supporting rings 17, located on the upper and lower sides of the cylinder 1. The cross-section is rectangular and relatively sturdy. On the one hand, it is used to support the first inner gear ring 3-3. The inner wall diameter is just the outer ring diameter of the first inner gear ring 3-3, which can just accommodate the first inner gear ring 3-3 and make the first inner gear ring 3-3 rotate in the supporting ring 17. On the other hand, it is connected with the reinforcing ribs to form a double-horizontal (two supporting rings 17) and multi-vertical (multiple reinforcing ribs) reinforcement skeleton of the equipment, which improves the overall rigidity and prevents the second inner gear ring 2-1 of the wind collection ring 2 from losing engagement due to the deformation of the cylinder 1. A plurality of outer baffles 22 are distributed on the outer edge of the supporting ring 17. The outer baffles 22 are semicircular structures, and the straight edges of the outer baffles 22 are connected to the inner wall of the cylinder 1. The outer baffles 22 are used to prevent the supporting ring 17 from moving up and down. There are several receiving holes on each of the two supporting rings 17. The receiving holes on the upper and lower supporting rings are coaxially arranged to accommodate the rigid rod 8 of the reversing mechanism. The rigid rod 8 of the reversing mechanism can reciprocate along the axial direction of the receiving holes, which is manifested as the up and down movement of the reversing mechanism relative to the cylinder 1 on a macro scale.

[0051] The wind power collection ring 2 is a component for collecting wind energy. When there is wind, the wind power collection ring 2 can rotate unidirectionally, converting wind energy into rotational mechanical energy, and transferring the kinetic energy through the receiving gear 5 meshing with it. Figure 7 and Figure 8 As shown, the wind collection ring 2 is composed of a structural ring 2-3, a second inner gear ring 2-1 and a wind collection bowl 2-2. The structural ring 2-3 is a circular ring-shaped component with a rectangular cross-section and great strength. A second inner gear ring 2-1 is concentrically arranged inside the structural ring 2-3. The second inner gear ring 2-1 is a spur internal gear, and its parameters such as module and face width are consistent with those of the receiving gear 5, and the two can mesh with each other. There are several wind collecting bowls 2-2, which are evenly arranged on the outside of the structural ring 2-3 along the circumference of the structural ring 2-3. The openings of the wind collecting bowls 2-2 are all facing in one direction along the circumference of the structural ring 2-3. The wind collecting bowls 2-2 are bowl-shaped components, and their number is proportional to the diameter of the insulator string and the required wind force. Its opening is flat and the bottom is smooth. The characteristic is that the wind resistance coefficient at the opening is much larger than the wind resistance coefficient at the bottom. When wind blows, the wind force at the opening is always greater than the wind force at the bottom. In this way, no matter which direction the wind blows from, the wind collection ring 2 will only rotate in the tangent direction of the bottom of the bowl.

[0052] A reflector is installed at the bottom of one or more wind-collecting bowls 2-2. The reflected sunlight can drive away nearby birds and prevent them from building nests on the insulator strings, thus achieving a bird-repelling effect. As long as the wind-collecting bowl 2-2 rotates, the structure is a good bird-repelling device, making the device have multiple functions and can be used as a bird-repelling device.

[0053] The receiving gear 5 is used to mesh with the second inner gear ring 2-1 of the wind collection ring 2. The number of receiving gears 5 is the same as the number of the running mechanism 4. When several receiving gears 5 mesh with the second inner gear ring 2-1 of the wind collection ring 2 at the same time, the wind collection ring 2 is axially fixed to the outer ring of the cylinder 1. Figure 8 , Fig. 9 As shown, the receiving gear is composed of an upper baffle 5-1, a gear body 5-4, a lower baffle 5-2, a supporting shaft 5-5 and a small-angle universal joint 5-3. The upper baffle 5-1 and the lower baffle 5-2 are circular components with a central through hole, and their diameters are slightly larger than the diameter of the tooth top circle of the gear body 5-4. The upper baffle 5-1 and the lower baffle 5-2 are both provided with chamfers at the outer edges of one end close to the gear body 5-4. After the second inner gear ring 2-1 is meshed with the gear body 5-4, the upper and lower end faces of the second inner gear ring 2-1 are aligned. The second inner gear ring 2-1 cannot move up and down, but can only rotate around the axis. It has only one degree of freedom, namely rotation. When the equipment is working, the wind collection ring 2 can only mesh with several receiving gears 5. At the same time, the up and down movement is restricted by the two baffles above and below the receiving gears 5. The chamfers on the outer edges of the two baffles are to facilitate the second inner gear ring 2-1 to rotate and mesh with the receiving gear 5, so that the gear body 5-4 will not touch the edges of the two baffles and cause tooth jamming. The supporting shaft 5-5 passes through the upper baffle 5-1, the gear body 5-4 and the lower baffle 5-2 from top to bottom. The supporting shaft 5-5 and the two triangular flat plates in the fork arm hinge seat 14 on the inner wall of the cylinder 1 are connected to each other through the upper and lower bearings. The gear body 5-4 can rotate around the axis of the supporting shaft 5-5 under the support of the supporting shaft 5-5 and the fork arm hinge seat 14. Figure 8 It can be seen that a part of the receiving gear 5 extends out from the square through hole of the outer shell of the cylinder 1 and meshes with the second inner gear ring 2-1 of the wind collection ring 2. The number of the transmission gears 5 is consistent with the number of the walking mechanism 4. Among them, the small angle universal joint 5-3 of the first group of receiving gears meshes with the transmission shaft, and the two ends of the transmission shaft are provided with small angle universal joints, which respectively mesh with the receiving gear 5 and the universal joints at the upper end of the power input shaft 6-9 in the power distributor 6 to transmit the power.

[0054] The power distributor contains three groups of mechanisms, such as Figure 3 , Fig.10 and Fig.11As shown, they are the double-sided output reduction gear set 6-1, the reversing frame 6-2 and the double-sided transmission differential 6-3. The upper part of the power input shaft 6-9 has a universal joint for receiving the power transmitted by the receiving gear 5, and transmitting the power to the multiple reduction gears of the double-sided output reduction gear set 6-1 through the gears at the lower part of the power input shaft 6-9. The reduction gears can adjust the speed and torque, greatly reduce the speed of the system, and greatly increase the torque. The last reduction gear of the double-sided output reduction gear set 6-1 meshes with the transmission gear set 6-6 to transmit the power to the transmission gear set 6-6. Fig.10 As shown, the transmission gear set 6-6 is composed of two coaxial gears arranged up and down, wherein the lower large gear meshes with the last reduction gear of the double-sided output reduction gear set 6-1 to receive power, and at the same time meshes with the gear on the lower cleaning ring power output shaft 6-7 to output power to the lower cleaning ring power output shaft 6-7. Figure 3 As shown, the gear on the lower cleaning ring power output shaft 6-7 meshes with the gear on the upper cleaning ring power output shaft 6-8. The small gear on the upper part of the transmission gear set 6-6 has a large face width and meshes with the floating reversing gear 6-5 to output power to the floating reversing gear 6-5. At the same time, since the transmission gear set 6-6 is composed of two gears, one large and one small, it also has a deceleration function. When the receiving gear 5 transmits power to the transmission gear set 6-6 through the bilateral output reduction gear set 6-1, it drives the lower cleaning ring power output shaft 6-7, the upper cleaning ring power output shaft 6-8 and the floating reversing gear 6-5 to rotate. As shown Fig.10 and Fig.11 As shown, the reversing frame 6-2 is a "sun" shaped structure in a vertical plane, wherein there is a square hole on the middle crossbeam, and the floating reversing gear 6-5 is installed in the square hole. The floating reversing gear 6-5 is rotatably installed on the reversing frame 6-2 through a vertical axis on the middle crossbeam of the reversing frame 6-2. The height of the square hole on the crossbeam of the reversing frame 6-2 is relatively large, which is larger than the width of the floating reversing gear 6-5. The floating reversing gear 6-5 can slide up and down a certain distance around the vertical axis on the crossbeam, providing a frame capacity for the automatic action of the mechanism. The reversing frame 6-2 can move up and down a certain distance in the vertical direction, and at the same time drive the floating reversing gear 6-5 to move up and down to a greater amplitude (because it has a frame capacity itself). No matter how it moves, the floating reversing gear 6-5 is always meshed with the small gear located above in the transmission gear set 6-6, that is, the floating reversing gear 6-5 can always maintain a powered state. There are only three states in which the floating reversing gear 6-5 transmits power downward: Figure 3 and Fig.11, first, it meshes with the upper gear of the bilateral transmission differential 6-3; second, it meshes with the idler wheel 6-4 below; third, the floating reversing gear 6-5 is located between the upper gear and the idler wheel 6-4, and does not mesh with any gear. Because there is a height difference between the three in the vertical direction, there is no situation where the floating reversing gear 6-5 is meshed with the other two at the same time. The idler wheel 6-4 is an independent gear. One side of the idler wheel 6-4 is always meshed with the lower gear of the bilateral transmission differential 6-3, and the other side of the idler wheel 6-4 is either meshed with the floating reversing gear 6-5 or is empty, not meshed with other gears, and does not receive power transmission. When the floating reversing gear 6-5 is meshed with the upper gear of the bilateral transmission differential 6-3, the bilateral transmission differential 6-3 keeps rotating in a certain direction; when the floating reversing gear 6-5 is meshed with the idler wheel 6-4, the bilateral transmission differential 6-3 rotates in the opposite direction. The double-sided transmission differential 6-3 has a differential structure inside, which can realize the function of a car differential. It has a rotating shaft on the upper and lower parts, which can transmit power to the outside. When one of them is stuck or encounters an obstacle and cannot rotate, the transmission action of the double-sided transmission differential 6-3 can transfer more power to the other transmission shaft, realizing the functions of power distribution and differential distribution. The gear at the bottom of the lower cleaning ring power output shaft 6-7 and the large wheel under the transmission gear set 6-6 are meshed with each other, which can transmit power to the lower cleaning ring through the universal joint, ensuring that the lower cleaning ring can keep rotating. Figure 3 and Figure 5 It can be seen that the gears connected to the upper cleaning ring power output shaft 6-8 and the lower cleaning ring power output shaft 6-7 are meshed with each other, so the rotation directions of the two cleaning ring power output shafts are always opposite, which can offset the tangential force generated during cleaning. The reversing frame 6-2 and the commutator and the rigid rod 8 are connected to each other, and several components form a reversing mechanism, which can realize automatic reversing cleaning of the equipment.

[0055] The reversing mechanism includes a reversing ring 7, a rigid rod 8, a reversing frame 6-2, and Fig.12 The commutator and other mechanisms shown in FIG. Figure 4 and Figure 5As shown, the frame of the reversing mechanism is composed of two upper and lower reversing retaining rings 7 and a plurality of slender rigid rods 8. The reversing retaining ring 7 is an annular component, which protrudes from the upper and lower ends of the shell of the cylinder 1. The upper and lower ends of the insulator generally have enlarged obstacles such as steel strands and bases. When the mechanism is moving, the reversing retaining ring 7 will first contact the obstacle; the two reversing retaining rings 7 are the structures that first contact the obstacle during the movement of the mechanism; the two reversing retaining rings 7 are firmly connected to form a rigid whole through a plurality of rigid rods 8 to form the frame of the reversing mechanism. The frame of the reversing mechanism as a whole can slide within a certain range relative to the shell of the cylinder 1, which means that when the equipment moves to the end where there is an obstacle, the frame of the reversing mechanism will no longer move forward due to the obstacle, and the cylinder 1 and its accessories will continue to move forward, so that the two slide relative to each other, caused by Figure 5 It can be seen that a reversing frame fixing plate 10 is fixed on the rigid rod 8 of the reversing mechanism, and the reversing frame fixing plate 10 is firmly connected to the commutation frame 6-2. Therefore, the relative movement of the reversing ring 7 will drive the movement of the reversing frame 6-2, and the floating reversing gear 6-5 on the reversing frame 6-2 will also move together. During the movement, the floating reversing gear 6-5 will either mesh with the upper gear of the bilateral transmission differential 6-3 or mesh with the idler gear 6-4. The different meshing states of the two directly lead to the rotation of the bilateral transmission differential 6-3. The direction of rotation is opposite, and the upper and lower shafts of the bilateral transmission differential 6-3 are connected to the walking mechanism 4, so that when the equipment reaches the end, the reversing ring 7 touches the obstacle and realizes reverse travel. When talking about the power distributor 6, the third instantaneous state of the floating reversing gear 6-5 transmitting power downward was mentioned, that is, the floating reversing gear 6-5 does not mesh with any gear, and the system is in a momentary neutral state. This state is momentary, and it is controlled by the commutator to instantly change the meshing state of the floating reversing gear 6-5. Fig.12 As shown, the commutator is an independent sliding mechanism. The shell 18 of the commutator is fixed on the inner wall of the cylinder 1. The slider 11 is a long strip-shaped component. The middle part of the slider 11 protrudes like a hill-like reversing protrusion. The slider 11 can slide up and down a certain distance relative to the shell 18. The top of the slider 11 is connected to the reversing frame 6-2 and moves up and down with the reversing frame 6-2. The pulley 12 is rotatably installed in the shell 18, and the left side of the outer rotating surface of the pulley 12 is in contact with the reversing protrusion on the slider 11. The side of the pulley 12 away from the reversing protrusion is connected with a transverse slider 19. A compression spring is connected between the transverse slider 19 and the shell, so that the transverse slider 19 can be slidably connected with the shell 18 in the transverse direction. The pulley 12 can only be above or below the hill-like transverse protrusion, because after the hill-like protrusion is pressed, both sides of the protrusion are slopes, which will force the hill-like transverse protrusion to move to the upper side or lower side.

[0056] After the automatic cleaning device moves to the top of the insulator, the reversing retaining ring 7 is blocked and cannot continue to move forward. However, at this time, the power distributor 6 has been working due to the transmission effect of the receiving gear 5 and the wind collection ring 2, thereby driving the walking mechanism 4 to drive the equipment to continue to move forward. The reversing mechanism moves relative to the outer shell of the cylinder 1, and the reversing retaining ring 7 and the rigid rod 8 move backward relative to each other, driving the reversing frame 6-2 to move. The square hole in the middle of the reversing frame 6-2 for receiving the floating reversing gear 6-5 is relatively large. When the commutator starts to move, it cannot contact the floating reversing gear 6-5. Therefore, the floating reversing gear 6-5 maintains the previous meshing state and does not move (here it is assumed that the floating reversing gear 6-5 is meshed with the gear of the bilateral transmission differential 6-3 at this time). When the reversing frame When 6-2 continues to move, the floating reversing gear 6-5 is pushed to move in the other direction. At the same time, the reversing frame 6-2 also drives the slider 11 to move. When the top of the lateral protrusion of the slider 11 passes over the pulley 12, the floating reversing gear 6-5 no longer meshes with the outer gear of the bilateral transmission differential 6-3. Since the pulley 12 has passed the top of the slider 11, under the action of the compression spring and the lateral slider 19, the slider 11 will continue to move forward. At this time, the slider 11 becomes a driving component, dragging the reversing frame 6-2 and other components to continue to move. The reversing frame 6-2 will drive the floating reversing gear 6-5 to move in the direction of the shunting wheel 6-4 until it meshes with the shunting wheel 6-4. At this time, the bilateral transmission differential 6-3 starts to rotate in the opposite direction, and the mechanism realizes reverse motion. When it moves to the other end, the mechanism repeats the above action and realizes reverse motion again. This is the structural principle of the reciprocating motion of the mechanism.

[0057] The number of walking mechanisms 4 corresponds to the number of receiving gears 5. In the embodiment of the present application, four walking mechanisms 4 and four receiving gears 5 are used as an example for description. Each walking mechanism 4 includes a walking execution end and a long-travel suspension system for supporting the walking execution end.

[0058] like Fig.13As shown, each group of walking execution ends includes a base plate 4-1, two end transmission wheels 4-2, two supporting transmission wheels 4-3, three fixed seats 4-4 and a crawler track 4-5. The base plate 4-1 is a basic component. The fixed seats 4-4, the supporting transmission wheels 4-3 and the end transmission wheels 4-2 are interconnected through the base plate 4-1. The three fixed seats 4-4 are respectively interconnected with the long-stroke suspension system. The long-stroke suspension system is movably installed on the inner wall of the cylinder 1, so that the walking execution end is well connected with the cylinder 1. The two end transmission wheels 4-2 are located at the two ends of the front of the base plate 4-1, and are used to receive the crawler 4-5 and rotate with the movement of the crawler 4-5. The base plate 4-1 is in the shape of an elongated isosceles trapezoid as a whole. The two supporting transmission wheels 4-3 are located at the two ends of the short side of the isosceles trapezoid. At the same time, the two supporting transmission wheels 4-3 also receive the crawler. The four wheels firmly support the crawler to form an isosceles trapezoid. The crawler 4-5 wrapped around the outside of the transmission wheel also presents an isosceles trapezoid structure. In the isosceles trapezoid structure, the outer side of the short side of the crawler 4-5 contacts the insulator, and the two ends of the contact surface form a certain angle, which greatly improves the passability. There are multiple anti-skid protrusions in the middle of the four transmission wheels to prevent relative sliding between the crawler 4-5 and the transmission wheel.

[0059] Among the four groups of walking mechanisms, two groups of walking mechanisms that are symmetrical about the center line of the cylinder 1 are selected. According to the positional relationship between the two supporting transmission wheels 4-3 and the power distributor 6, one of them is selected as the driving wheel and the other is the driven wheel. The driving wheel and the output shaft of the double-sided transmission differential 6-3 on the power distributor 6 are connected to each other through a flexible shaft. Figure 3 As shown, the double-sided transmission differential 6-3 has two output shafts, one on the upper and the other on the lower output shaft, and two symmetrical driving wheels on the two sets of walking mechanisms, one connected to the upper output shaft and the other connected to the lower output shaft. The flexible shaft is a shaft with very low rigidity and elasticity that can be freely bent and driven. It is used to connect two parts with different axes and in different directions to transmit rotational motion and torque, and can flexibly transmit rotational motion and torque to any position. No matter where the walking mechanism 4 moves to, the power can be transmitted to the driving wheel through the flexible shaft, and the crawler 4-5 is driven by the driving wheel to move, so as to realize the movement of travel.

[0060] like Figure 6 and Fig.14As shown, each large-stroke suspension system includes two arc-shaped swing arms 15, a V-shaped fork arm 16 and a spring 20. The arc-shaped swing arms 15 and the V-shaped fork arm 16 are both arc-shaped, and their curvature is consistent with the curvature of the cylinder 1, so that the most space can be saved and the longest length can be ensured. The longer the arc-shaped swing arms 15 and the V-shaped fork arm 16 are, the longer the suspension stroke is. The present invention cleverly utilizes the curvature of the arc-shaped swing arms 15 and the V-shaped fork arm 16 to increase the length, reduce the space occupancy, and achieve the longest suspension stroke. Both ends of the arc-shaped swing arms 15 are equipped with joint bearings, wherein the joint bearing at one end is connected to the fixed seats 4-4 on the upper and lower sides, and the joint bearing at the other end is connected to the swing arm hinge seat 13. Through the joint bearing connection, the walking execution end can be rotated at a certain angle relative to the inner wall of the cylinder 1 within the spatial range, so that the walking execution end is more closely fitted to the insulator. Even if the insulator is conical, the walking execution end can be well fitted to achieve maximum power. The open end of the V-shaped fork arm 16 is rotatably connected to the fork arm hinge seat 14 at the end of the two legs through a joint bearing, and the tip of the V-shaped fork arm 16 is also connected to the fixed seat 4-4 in the middle position of the base plate 4-1 through a joint bearing. The walking execution end can rotate relatively around the hinge point of the V-shaped fork arm 16, and the two arc-shaped swing arms 15 will also swing accordingly. Multiple components cooperate with each other to form the travel of the walking execution end and the characteristics of being able to turn an angle. The spring 20 acts between the middle part of the V-shaped fork arm 16 and the inner wall of the cylinder 1, pushing the V-shaped fork arm 16 to move toward the center. Since the connection point of the V-shaped fork arm 16 is located at the center of the walking execution end, it can drive the entire walking execution end to move as a whole. When encountering insulator strings of different shapes and different curvatures, the displacement of the two arc-shaped swing arms 15 is dislocated, and when the track wheel rotates, the entire track wheel can completely fit the insulator under the support force of the spring 20. Under the action of the spring 20, the entire traveling mechanism 4 can be tightly attached to the insulator and drive the entire cleaning device to reciprocate along the insulator.

[0061] like Fig.15 and 16As shown, the cleaning mechanism includes a first inner gear ring 3-3, a centripetal brush 3-1 and a brush ring 3-2. The outer edge of the centripetal brush 3-1 is fixed on the brush ring 3-2. The centripetal brush 3-1 is a tough brush made of synthetic nylon or plastic material, and its direction points to the axis where the center of the circle is located; the brush ring 3-2 is a circular ring-shaped component, and its cross-section is rectangular. The outermost side of the brush ring 3-2 is rotatably connected to the supporting ring 17. The first inner gear ring 3-3 is fixed to the outer edge of the upper surface of the brush ring 3-2 by a plurality of screws. The supporting ring 17 can just accommodate and support the first inner gear ring 3-3, so that the brush ring 3-2 can rotate in the supporting ring 17; the first inner gear ring 3-3 is transmission-connected to a transfer gear 24 on one side close to the inside of the barrel 1, which is used to receive power and distribute the power transmitted therefrom, and convert the power into rotation of the first inner gear ring 3-3. As shown in Figure 6, a plurality of outer baffles 22 are distributed on the outer edge of the support ring 17. The outer baffles 22 can block the brush ring 3-2 so that it cannot fall from the upper and lower sides, thus playing a role of limiting. The first inner gear ring fixer is a mechanism for fixing the first inner gear ring 3-3 and providing rotational power for the first inner gear ring 3-3. Fig.15 and Fig.16As shown, the first inner gear ring fixer is composed of a fixing plate 21, a bearing wheel 25, a transfer gear 24 and a universal joint 23. The transfer gear 24 and the universal joint 23 are coaxial mechanisms, and the transfer gear 24 and the universal joint 23 are interconnected. The power distributor 6 drives the universal joint 23 to rotate, and the transfer gear 24 also rotates. The transfer gear 24 is meshed with the first inner gear ring 3-3. The rotation of the transfer gear 24 will drive the first inner gear ring 3-3 to rotate, and then the brush ring 3-2 will rotate; the bearing wheel 25 is a bearing coated with rubber on the outside, which can rotate freely. The bearing wheel 25 is tangent to the outer edge of the brush ring 3-2. On the one hand, it cooperates with the transfer gear 24 to firmly clamp the first inner gear ring 3-3 to prevent tooth hitting. On the other hand, the bearing has the characteristic of small resistance, which can make the first inner gear ring 3-3 rotate more smoothly. At the same time, the outer end of the fixing plate 21 is connected to the support ring 17 through the connecting piece 9, and the inner end of the fixing plate 21 extends toward the center of the cylinder 1, crossing the first inner gear ring 3-3, and fixing the first inner gear ring 3-3 in the support ring 17, so that it can only make rotational movement in the support ring 17. There are multiple first inner gear ring fixers arranged along the circumference of the support ring 17, which are fixed to the inner side of the support ring 17 by screws, which is convenient for the assembly of the mechanism. Multiple first inner gear ring fixers firmly restrict the first inner gear ring 3-3 in the working position. The structures of the first inner gear ring fixers at both ends of the cylinder 1 are the same, but there is only one universal joint 23 of the first inner gear ring fixer at each end connected to the power distributor 6 through the shaft, that is, only one transfer gear 24 at each end of the cylinder is active, and the rest are driven. As a driven structure, the transfer gear 24 can only limit and make the mechanism move more smoothly. The power distributor 6 can make the upper and lower first inner gear rings 3-3 rotate counterclockwise and clockwise respectively. When the first inner gear ring 3-3 rotates, the brush 3-1 on the brush ring 3-2 will rotate relative to the insulator, that is, rotational cleaning. Combined with the action of the upper walking mechanism 4, the two are coupled to present a spiral cleaning effect as a whole. The cleaning effect is more obvious and there is no cleaning dead angle. Each device has two upper and lower first inner gear rings 3-3. The equipment can achieve four cleanings in one reciprocating motion, and the cleaning frequency is high.
