[0002] Insulators are crucial insulating components in power systems, typically installed on transmission line towers to support conductors and maintain insulation between them. To improve their anti-flashover performance, insulators are usually coated with a silicone rubber layer. However, over time, this coating can lose its protective effect due to aging, cracking, and peeling, and may even become a potential flashover hazard. Therefore, regularly removing the old silicone rubber coating and reapplying a new one is an essential part of power equipment maintenance.

[0003] Currently, removing old silicone rubber coatings from insulators mainly relies on manual operation, which is inefficient and labor-intensive. Static electricity may be generated during the removal process, which may pose safety hazards to operators and equipment if not eliminated in time. Utility Model Content

[0014] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0015] refer to Figure 1-6 Example 1: Equipment for removing old silicone rubber coating from insulators, including a working head 1, a support rod 3, a spacing adjustment component 4, two cleaning connection plates 5, an angle adjustment component 6, several cleaning nozzles 7, a first telescopic pipe 8, a fixed pipe 9, a second telescopic pipe 11, a telescopic sealing sleeve 12, and an electrostatic elimination module 13.

[0016] The working head 1 is fixedly installed on the top of the support rod 3. The operator can adjust the position of the working head 1 by holding the support rod 3. The working head 1 has an installation groove 101 in the middle and sliding grooves 102 on both sides.

[0017] refer to Figure 2 , Figure 3 Two mounting plates 2 are symmetrically arranged in the mounting groove 101 and slide in contact with the inner wall of the mounting groove 101; the spacing adjustment assembly 4 is installed in the mounting groove 101, and the two ends of the guide rod 41 are fixedly connected to the two side walls of the mounting groove 101 respectively, and pass through the two mounting plates 2 and slide in contact with the mounting plates 2; the two ends of the screw 42 are rotatably connected to the two side walls of the mounting groove 101 through bearings, and the first threaded section 421 and the second threaded section 422 on the screw 42 are threadedly connected to the two mounting plates 2 respectively, and the thread directions are opposite; the spacing adjustment handle 43 is welded to one end of the screw 42 and extends to the outside of the working head 1.

[0018] refer to Figure 5 Two cleaning connection plates 5 are respectively hinged to two mounting plates 2. The cleaning connection plates 5 have an arc structure, and 4-6 cleaning nozzles 7 are evenly spaced along the inner side wall. The nozzles face the surface of the insulator.

[0019] refer to Figure 5 , Figure 6 Angle adjustment component 6 is installed on the side of mounting plate 2. Positioning groove 61 is opened on the side of mounting plate 2. Positioning plate 62 is embedded in positioning groove 61 and slides in cooperation with positioning groove 61. One end of second spring 63 is fixedly connected to the bottom of positioning groove 61, and the other end is fixedly connected to the bottom of positioning plate 62, always providing upward elastic force to positioning plate 62. Positioning rod 64 is vertically welded to the top of positioning plate 62. Multiple positioning holes 65 are evenly opened in the circumferential direction at the hinge end of cleaning connecting plate 5. The top of positioning rod 64 is embedded in positioning hole 65 to realize the angle fixation of cleaning connecting plate 5. Pressing down positioning plate 62 can disengage positioning rod 64 from positioning hole 65. After adjusting the angle of cleaning connecting plate 5, release positioning plate 62. Positioning rod 64 is embedded in corresponding positioning hole 65 under the action of second spring 63 to complete positioning.

[0020] refer to Figure 2 The two ends of the first retractable pipe 8 are respectively connected to the internal channels of the two cleaning connecting plates 5, and the connection is fitted with a sealing ring; the fixed pipe 9 is detachably fixed to the support rod 3 by the buckle 10. The input end of the fixed pipe 9 is connected to the external cleaning fluid supply device, and the output end is connected to the internal channel of one of the cleaning connecting plates 5 through the second retractable pipe 11. The connection between the second retractable pipe 11 and the fixed pipe 9 and the cleaning connecting plate 5 is equipped with a sealing ring to ensure that there is no leakage during the delivery of cleaning fluid.

[0021] The telescopic sealing sleeve 12 is made of corrosion-resistant and telescopic rubber material, and its two ends are fixedly connected to the edges of the two cleaning connection plates 5 to form a closed cleaning space.

[0022] refer to Figure 3 , Figure 4The probe mounting bracket 132 of the electrostatic elimination module 13 is embedded in the sliding groove 102 and slides in cooperation with the sliding groove 102; one end of the first spring 134 is fixedly connected to the bottom of the sliding groove 102, and the other end is fixedly connected to the bottom of the probe mounting bracket 132; the electrostatic induction probe 131 is evenly installed circumferentially at the lower end of the probe mounting bracket 132, facing the insulator; the pulse electrostatic discharger 133 is fixed to the top of the working head 1 by bolts and is electrically connected to the electrostatic induction probe 131 by wires; the bellows sealing strip 135 is fitted on the outside of the probe mounting bracket 132, and its two ends are fixedly connected to the port of the sliding groove 102 and the middle of the probe mounting bracket 132 respectively, so as to seal the sliding groove 102; a wiring groove 136 is opened on the side of the probe mounting bracket 132, and the wires pass through the wiring groove 136 to connect the electrostatic induction probe 131 and the pulse electrostatic discharger 133, so as to avoid the wires from tangling.

[0023] In use, depending on the insulator to be coated, rotate the spacing adjustment handle 43 to drive the screw 42 to rotate. Since the first thread section 421 and the second thread section 422 have opposite thread directions, the two mounting plates 2 move closer or further apart along the guide rod 41 until the spacing between the two cleaning connecting plates 5 is suitable for the insulator, and the telescopic sealing sleeve 12 extends and retracts accordingly. A positioning handle is connected to the positioning plate 62. Pulling the positioning handle causes the positioning rod 64 to disengage from the positioning hole 65. Rotating the cleaning connecting plate 5 causes the cleaning nozzle 7 to align with the curved surface contour of the insulator. Releasing the positioning plate 62 causes the positioning rod 64 to be inserted into the corresponding positioning hole 65 under the action of the second spring 63, thus fixing the angle of the cleaning connecting plate 5. When the pulse electrostatic discharger 133 is activated, the electrostatic induction probe 131 detects the electrostatic intensity on the surface of the insulator and the surrounding environment in real time. When the electrostatic intensity exceeds the set threshold, the pulse electrostatic discharger 133 releases a pulse current, which is transmitted to the electrostatic induction probe 131 through the wire to neutralize and eliminate the surrounding static electricity. The external cleaning fluid supply device is connected to the fixed pipe 9. The cleaning fluid enters one of the cleaning connection plates 5 through the fixed pipe 9 and the second telescopic pipe 11, and then is diverted to the other cleaning connection plate 5 through the first telescopic pipe 8. Finally, it is sprayed out from each cleaning nozzle 7 to remove the old silicone rubber coating on the surface of the insulator. The telescopic sealing sleeve 12 forms a closed space to prevent the cleaning fluid from splashing and the dust from spreading.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
