[0002] In power grids, for safe operation, it is necessary to shut down energized electrical equipment for maintenance or disconnect electrical equipment in standby mode. Disconnect switches are used to set disconnect points in the circuit to ensure the safety of power grid operation and maintenance. However, the conductive parts of GW4 type disconnect switches become dirty and oxidize faster due to smoke and dust emitted by the factory, which increases the contact resistance of the disconnect switch and causes the contacts to overheat. If not dealt with in time, it will cause serious accidents such as red-hot joints or even burnout. Therefore, it is necessary to clean the surface of the disconnect switch in a timely manner. The traditional cleaning method is to manually climb up to the disconnect switch to clean it. This method is time-consuming and laborious, and the safety of the workers cannot be fully guaranteed.

[0030] Example 1

[0031] Referring to Figures 1 and 2, a first embodiment of the present invention provides a cleaning device for the stationary contact of an isolating switch, including an adjustment mechanism 100, comprising a chassis 101, casters 102 fixedly connected to the bottom of the chassis 101, and a support rod 103 disposed on the chassis 101; a cleaning mechanism 200, comprising a control component 201 disposed within the support rod 103, and a cleaning component 202 disposed at the end of the support rod 103; movable grooves 103a are provided on both sides of the support rod 103, and the movable grooves 103a are provided with... The locking slot 103b has a limit rod 103c fixedly connected to the inner wall of the support rod 103. There are two sets of limit rods 103c. It is worth noting that the support rod 103 is fixedly connected to the chassis 101, which allows the device to move in any direction. The control component 201 inside the support rod 103 can control the raising and lowering of the overall cleaning component 202, and can also control the opening and closing. This is beneficial for the device to first lock the stationary contact of the disconnect switch, and then carry out the cleaning work around the stationary contact of the disconnect switch, so that the stationary contact of the disconnect switch is cleaned more thoroughly.

[0032] Specifically, the control component 201 includes a locking member 201a connected to the inner wall of the support rod 103, a handle 201b penetrating the locking member 201a, an eccentric member 201c connected to the handle 201b, and a clamping member 201d disposed on the eccentric member 201c. The handle 201b includes a rod shaft 201b-1 and a handle 201b-2. The rod shaft 201b-1 penetrates the support rod 103 through a moving groove 103a. It is worth noting that the locking member 201a serves to limit and adjust the height of the overall device, which is beneficial for adapting to the stationary contacts of the isolating switch at different heights. When the handle 201b is rotated, due to the... An eccentric component 201c is provided, allowing the clamping component 201d to open and close following the height change of the eccentric component 201c, which facilitates the engagement of the entire device with the stationary contact of the disconnecting switch. It should also be noted that the rod shaft 201b-1 passes through the support rod 103, and a handle 201b-2 is fixedly connected to one end of the rod shaft 201b-1. Two sets of engaging components 201a and eccentric components 201c are provided, and they are mirror images of the center of the rod shaft 201b-1 as the origin. That is, two sets of engaging components 201a and eccentric components 201c pass through both sides of the rod shaft 201b-1, and both sets of engaging components 201a and eccentric components 201c are located inside the support rod 103.

[0033] Operating Procedure: When cleaning the stationary contact of the high-level disconnector switch, first adjust the cleaning head to be flush with the stationary contact of the disconnector switch. Specifically, simultaneously grasp the handle 201b-2 and the strip plate 201a-1b on the first positioning plate 201a-1. Move the handle 201b-2 towards the strip plate 201a-1b, that is, grip the handle 201b-2 and the strip plate 201a-1b tightly. Since the handle 201b-2 is fixedly connected to the rod shaft 201b-1, when the handle 201b-2 moves towards the strip plate 201a-1b, the rod shaft 201b-1 will... The bottom end of the positioning groove 201a-1a of the first positioning plate 201a-1 moves to the top end of the positioning groove 201a-1a. Simultaneously, the rod shaft 201b-1 also moves from the bottom end of the first displacement groove 201a-2b and the second displacement groove 201a-3a to their top ends. Since both the first displacement plate 201a-2 and the second displacement plate 201a-3a can move along the end face of the first positioning plate 201a-1, when the rod shaft 201b-1 moves along the first displacement groove 201a-2b and the second displacement groove 201a-3a, the first displacement plate 201a-2 and the second displacement plate 201a-3a move simultaneously. 3. Simultaneously move towards the center of the first positioning plate 201a-1, causing the locking blocks 201a-2a on the first displacement plate 201a-2 and the second displacement plate 201a-3 to move simultaneously until they no longer contact the locking groove 103b. This allows the handle 201b to be moved along the moving groove 103a on the support rod 103, thus changing the height of the lifting rod 201c-2a and consequently the height of the cleaning head to accommodate different heights of the isolating switch stationary contacts. After adjusting the cleaning head to the appropriate position, release the handle 201b-2, and under gravity, the rod shaft 201b-1 moves along... The top of the positioning groove 201a-1a moves to the bottom of the positioning groove 201a-1a. During the downward movement of the rod shaft 201b-1, the rod shaft 201b-1 moves simultaneously along the first displacement groove 201a-2b and the second displacement groove 201a-3a, causing the first displacement plate 201a-2 and the second displacement plate 201a-3 to move simultaneously away from the center of the first positioning plate 201a-1. This causes the locking blocks 201a-2a on the first displacement plate 201a-2 and the second displacement plate 201a-3 to move simultaneously to engage with the locking groove 103b. At this time, the overall height of the device is fixed.

[0034] Example 2

[0035] Referring to Figures 4 to 6, this embodiment differs from the first embodiment in that: the engaging component 201a includes a first positioning plate 201a-1 connected to the handle 201b, a first displacement plate 201a-2 connected to the first positioning plate 201a-1, and a second displacement plate 201a-3 connected to the first positioning plate 201a-1; a positioning groove 201a-1a is provided in the middle of the first positioning plate 201a-1, and a strip plate 201a-1 is fixedly connected to the end of the first positioning plate 201a-1. b. It is worth noting that the function of the first positioning plate 201a-1 is to limit the movement trajectory of the rod shaft 201b-1. When the rod 201b moves upward along the first positioning plate 201a-1, the first displacement plate 201a-2 and the second displacement plate 201a-3 will move towards the center of the first positioning plate 201a-1 at the same time. The interior of the first displacement plate 201a-2 has a receiving groove, which allows the second displacement plate 201a-3 to move along the inner wall of the first displacement plate 201a-2.

[0036] Specifically, both the first displacement plate 201a-2 and the second displacement plate 201a-3 are provided with engaging blocks 201a-2a on their sides. A sliding block is fixedly connected to the end of the engaging block 201a-2a near the first positioning plate 201a-1. A sliding groove is formed at the end of the first positioning plate 201a-1 near the engaging block 201a-2a. The sliding groove is horizontally set so that the direction of the sliding groove and the moving groove 103a are perpendicular to each other. The sliding block is adapted to the sliding groove so that both the first displacement plate 201a-2 and the second displacement plate 201a-3 can move along the end face of the first positioning plate 201a-1. A first displacement groove 201a-2b is formed on the first displacement plate 201a-2, and a second displacement groove 201a-3a is formed on the second displacement plate 201a-3. The first displacement groove 201a-2b and the second displacement groove 201a-3a are mirror images of each other, as are the first displacement plate 201a-2 and the second displacement plate 201a-3. The bottom ends of the positioning groove 201a-1a, the first displacement groove 201a-2b, and the second displacement groove 201a-3a all overlap. It is worth noting that, since the bottom ends of the positioning groove 201a-1a, the first displacement groove 201a-2b, and the second displacement groove 201a-3a are all aligned... The bottom ends of displacement grooves 201a-3a all overlap, allowing the handle 201b to pass through positioning groove 201a-1a, the first displacement groove 201a-2b, and the second displacement groove 201a-3a simultaneously. This means that when the handle 201b moves upward along the positioning groove 201a-1a of the first positioning plate 201a-1, it will simultaneously move along both the first displacement groove 201a-2b and the second displacement groove 201a-3a. Consequently, when the handle 201b moves upward along the positioning groove 201a-1a of the first positioning plate 201a-1, the first displacement plate 201a-2b and the second displacement groove 201a-3a... The displacement plate 201a-3 will move towards the middle of the first positioning plate 201a-1 at the same time. When the first displacement plate 201a-2 and the second displacement plate 201a-3 move towards the middle of the first positioning plate 201a-1 at the same time, the locking block 201a-2a, which is fixedly connected to the first displacement plate 201a-2 and the second displacement plate 201a-3, will move from the locking groove 103b on the support rod 103 to no longer contact the locking groove 103b. At this time, the handle 201b can be moved up or down to adjust the height of the device so as to adapt to the stationary contact of the isolating switch at different heights.

[0037] The eccentric component 201c includes an eccentric plate 201c-1 mounted on the handlebar 201b and a support plate 201c-2 fixedly connected to the end of the eccentric plate 201c-1. An eccentric roller 201c-1a is provided inside the eccentric plate 201c-1, and the shaft 201b-1 passes through the eccentric roller 201c-1a. The outer wall of the eccentric roller 201c-1a can rotate along the inner wall of the eccentric plate 201c-1. It is worth noting that since the shaft 201b-1 and the eccentric roller 201c-1a are fixedly connected, when the handlebar 201b-2 is rotated, the shaft 201b-1 drives the eccentric roller 201c-1a to rotate simultaneously, causing the height of the support plate 201c-2 driven by the eccentric plate 201c-1 to change.

[0038] Furthermore, the clamping component 201d includes a push-pull rod 201d-1 fixedly connected to the end of the support plate 201c-2, a limiting block 201d-2 fixedly connected to the end of the support rod 103, and a clamping plate 201d-3 connected to the limiting block 201d-2; a limiting groove 201d-2a is formed on one side of the limiting block 201d-2, and the end of the push-pull rod 201d-1 away from the support plate 201c-2 is inserted into the limiting groove 201d-2a; a spring rod 201d-2b is fixedly connected between the limiting block 201d-2 and the clamping plate 201d-3. It is worth noting that the function of the eccentric plate 201c-1 is to change the position of the push-pull rod 201d-2. When the height of the rod shaft 201b-1 changes, causing the eccentric plate 201c-1 to drive the support plate 201c-2 to change height, the push-pull rod 201d-1 will move upward or downward simultaneously. Since the limiting groove 201d-2a is set as an inclined ellipse, with the highest vertex of the ellipse being the first vertex and the lowest vertex being the second vertex, when the height of the push-pull rod 201d-1 changes from low to high, the push-pull rod 201d-1 moves along the limiting groove 201d-2a to the first vertex, and when the height of the push-pull rod 201d-1 changes from high to low, the push-pull rod 201d-1 moves along the limiting groove 201d-2a from the first vertex to the second vertex.

[0039] Furthermore, a connecting rope is fixedly connected to the side of the push-pull rod 201d-1 near the elastic rod 201d-2b. The end of the connecting rope away from the push-pull rod 201d-1 passes through the limiting groove 201d-2a and the elastic rod 201d-2b and is fixedly connected to the clamping plate 201d-3. It is worth noting that the elastic rod 201d-2b is telescopic. When the height of the push-pull rod 201d-1 changes, one end of the push-pull rod 201d-1 moves along the limiting groove 201d-2a of the limiting block 201d-2. When the height of the push-pull rod 201d-1 changes, one end of the push-pull rod 201d-1 moves along the limiting groove 201d-2a of the limiting block 201d-2. When the angle changes from low to high, the push-pull rod 201d-1 moves along the limit groove 201d-2a to the first vertex. At this time, the push-pull rod 201d-1 pulls the connecting rope and moves to the first vertex at the same time, so that the connecting rope pulls the clamping plate 201d-3 to move towards the moving block. Since the clamping plates 201d-3 on both sides move at the same time and in the same direction, the angle between the clamping plates 201d-3 on both sides becomes larger. That is, the clamping plates 201d-3 are in an open state at this time, so that the two sets of clamping plates 201d-3 can pass through the stationary contact of the isolating switch.

[0040] Furthermore, a lifting rod 201c-2a is fixedly connected to the end of the support plate 201c-2. The end of the lifting rod 201c-2a away from the support plate 201c-2 passes through the end of the support rod 103 and is fixedly connected to the bottom of the limiting block 201d-2. The lifting rod 201c-2a passes through two sets of limiting rods 103c. It is worth noting that the function of the lifting rod 201c-2a is to change the height of the cleaning head, so that the cleaning head can adapt to the stationary contacts of the isolating switch at different heights. Specifically, the lifting rod 201c-2a is fixedly connected to the support plate 201c-2, so that the height of the lifting rod 201c-2a can be adjusted by moving the handle 201b along the moving groove 103a of the support rod 103, thereby achieving the purpose of adjusting the height of the cleaning head.

[0041] The rest of the structure is the same as in Example 1.

[0042] Operation process: When the handle 201b-2 is rotated, the rod shaft 201b-1, which is fixedly connected to the handle 201b-2, rotates simultaneously, causing the eccentric roller 201c-1a, which is fixedly connected to the rod shaft 201b-1, to rotate simultaneously. When the rod shaft 201b-1 drives the eccentric roller 201c-1a to move to the highest point of the eccentric plate 201c-1, the eccentric plate 201c-1 drives the support plate 201c-2 to rise in overall height, causing the push-pull rod 201d-1 to move along the limiting groove 201d-2a on the limiting block 201d-2 to the first apex. At this time, the push-pull rod 201d-1 pulls the clamping plate 201d-3 through the connecting rope, causing the clamping plate 201d-3 to move towards the limiting block 201d-2. At this time, the two sets of clamping plates 201d-2... When 1d-3 is in the open state, the device can be moved until the stationary contact of the disconnecting switch is moved between the two sets of clamping plates 201d-3. Then, continue to rotate the lever 201b until the lever shaft 201b-1 drives the eccentric roller 201c-1a to move to the lowest point of the eccentric plate 201c-1. At this time, the eccentric plate 201c-1 drives the support plate 201c-2 to decrease in overall height, so that the push-pull rod 201d-1 moves along the limiting groove 201d-2a on the limiting block 201d-2 to the second apex. At this time, the connecting rope moves towards the clamping plate 201d-3 under the elastic force of the elastic rod 201d-2b, so that the clamping plate 201d-3 returns to the initial state. At this time, the stationary contact of the disconnecting switch is located at the center of the first track 202a.

[0043] Example 3

[0044] Referring to Figures 4 to 6, this embodiment differs from the previous embodiments in that: the cleaning component 202 includes a first track 202a fixedly connected to the clamping plate 201d-3, and a first cleaning rod 202b disposed on the first track 202a; a motor is fixedly connected to the bottom of the first cleaning rod 202b; the first track 202a is semi-circular and divided into left and right sides; a groove is provided on the first track 202a; it is worth noting that the left and right sides of the first track 202a are connected by hinges, so that the left and right sides of the first track 202a can open simultaneously with the clamping plate 201d-3; the first cleaning rod 202b can reciprocate along the first track 202a under the action of the motor, and the first cleaning rod 202b will not detach from the first track 202a under the action of the groove.

[0045] Specifically, the first cleaning rod 202b is fixedly connected to the second track 202b-1, which is semi-circular and located inside the first track 202a. The end of the second track 202b-1 away from the first cleaning rod 202b extends out of the first track 202a, and the end of the second track 202b-1 away from the first cleaning rod 202b is fixedly connected to the second cleaning rod 202b-1a. It is worth noting that the second track 202b-1 is also divided into left and right sides, and the left and right sides of the second track 202b-1 are also connected by hinges, so that the second track 202b-1 can open simultaneously with the first track 202a.

[0046] The rest of the structure is the same as in Example 2.

[0047] Operating procedure: When cleaning the stationary contact of the disconnector switch begins, the motor is first turned on, allowing the first cleaning head to move along the first track 202a. The first cleaning head can reciprocate along the first track 202a under the action of the motor. When the first cleaning head moves along the first track 202a, it pushes the second track 202b-1 and the second cleaning head on the second track 202b-1 to make circular motion simultaneously, so as to achieve a more thorough cleaning of the stationary contact of the disconnector switch.
