[0002] In the safe and stable operation system of the power system, the high-voltage equipment in the power plant and the transformer substation is the core component, and such equipment is equipped with a large number of outdoor high insulating porcelain bottles. As a key component to ensure the insulation performance of high-voltage equipment, the insulation reliability of insulating porcelain bottles is directly related to the safe operation of the entire power system. However, since the insulating porcelain bottles are exposed to the outdoor natural environment for a long time, they are prone to attach dust, oil stains, industrial pollutants and other types of dirt and impurities. These dirt will gradually reduce the insulation strength of the insulating porcelain bottles, and if not cleaned in time, it will easily cause flashover failure under certain conditions such as humid weather, and then cause serious problems such as power equipment tripping and shutdown, affecting the safe and stable operation of the power system. Therefore, regular cleaning of outdoor high insulating porcelain bottles is a necessary operation and maintenance measure to ensure the reliable operation of the power system.

[0003] At present, for the cleaning operation of outdoor high-voltage equipment insulating porcelain bottles, the industry mainly adopts the traditional manual climbing cleaning method. Specifically, this method needs to set up a scaffold or use a lifting operation vehicle to transport workers to a high-altitude operation area of 10 meters or more, and the workers manually complete the cleaning operation of the insulating porcelain bottles. However, this traditional cleaning method has the following problems: on the one hand, the high-altitude operation environment itself has a high risk, the workers face the risk of falling and electric shock, the professional skills and safety protection of the workers are required, and the probability of safety accidents is difficult to completely control; on the other hand, setting up a scaffold needs to consume a lot of manpower, material resources and time, the operation preparation period is long, and the efficiency of subsequent manual cleaning operation is also relatively low, the overall operation process is time-consuming and laborious, which seriously affects the overall efficiency of power operation and maintenance, and it is difficult to meet the needs of power system for timely and efficient operation and maintenance.

[0004] In summary, the existing outdoor high-voltage insulating porcelain bottle cleaning method has the problems of high safety risk of high-altitude operation, low operation efficiency, time-consuming and laborious, etc., which has become a key bottleneck restricting the improvement of power operation and maintenance quality and efficiency. Therefore, developing an insulating porcelain bottle cleaning technology that can avoid the risk of manual high-altitude operation, improve the cleaning efficiency and reduce the operation intensity has become a technical demand urgently to be solved in the current power operation and maintenance field, and has important practical significance and application value.

Operators can issue control commands through the touch screen and can also preset cleaning parameters to realize fully automatic cleaning operations.

[0027] Example 2 See attached Figures 1-5 This embodiment also provides a method for cleaning high-voltage insulating porcelain insulators, which uses the high-voltage insulating porcelain insulator cleaning device described in the above embodiment for cleaning operations, and specifically includes the following steps: S1, the device is moved to the work area corresponding to the insulating porcelain insulator to be cleaned via the mobile support unit 1. Specifically, the operator moves the device to the work area corresponding to the insulating porcelain insulator to be cleaned using the push-pull handle of the mobile support unit 1 and the casters 12, then presses the brake locking mechanism of the casters 12 to fix the device in position; the equipment power is turned on via the human-machine interface of the control unit 3 to complete the equipment self-check and ensure that each unit is operating normally.

[0028] S2, the adaptive opening and closing cleaning unit 5 is opened by the control unit 3, so that the adaptive opening and closing cleaning unit 5 is adjusted to a suitable size according to the diameter of the porcelain bottle to be cleaned and then fitted onto the outside of the porcelain bottle to be cleaned. Specifically, the control unit 3 drives the displacement adjustment unit 4 to move the adaptive opening and closing cleaning unit 5 to the approximate area of ​​the porcelain bottle to be cleaned by issuing a command through the human-machine interface; the vision detection component collects the image of the porcelain bottle and transmits it to the control unit 3, the control unit 3 identifies the position of the porcelain bottle and the degree of dirt, and at the same time the distance detection component detects the relative distance between the adaptive opening and closing cleaning unit 5 and the porcelain bottle. The control unit 3 outputs an adjustment command according to the detection data, drives the double output shaft hydraulic rod to move, and drives the left and right compartments to open synchronously. After moving to the outside of the porcelain bottle, the left and right compartments are then driven to close synchronously, adjusting to a size suitable for the diameter of the porcelain bottle, completing the fitting and positioning.

[0029] S3, the control unit 3 starts the cleaning medium supply unit 2, which delivers the cleaning medium to the cleaning execution component of the adaptive opening and closing cleaning unit 5, and simultaneously controls the cleaning execution component to complete the cleaning of the porcelain bottle. Specifically, the control unit 3 selects the corresponding cleaning medium according to the degree of dirt on the porcelain bottle. If it is lightly dirty, the control unit 24 switches to the high-pressure water supply mode, and starts the high-pressure water circulation module 23 and the air compression module 21. The high-pressure water is atomized through the delivery pipeline 25 and the cleaning nozzle 56 and sprayed onto the surface of the porcelain bottle. At the same time, the self-rotating cleaning brush 55 is started to brush the surface of the porcelain bottle. If it is moderately or heavily dirty, the control unit 24 can be switched to the dry ice supply mode, and the dry ice generation module 22 and the air compression module 21 are started. Pressurized dry ice particles are sprayed onto the surface of the porcelain bottle through the delivery pipeline 25 and the cleaning nozzle 56. The low-temperature sublimation effect of dry ice is used to remove stubborn stains. At the same time, the self-rotating cleaning brush 55 is started to assist in brushing.

[0030] S4. After cleaning is completed, the control unit 3 shuts down the cleaning medium supply unit 2 and the cleaning execution component, drives the adaptive opening and closing cleaning unit 5 to open, and then resets the device through the moving support unit 1 to complete the cleaning operation. Specifically, after cleaning is completed, the control unit 3 shuts down the cleaning medium supply unit 2 and the self-rotating cleaning brush 55; then it drives the synchronous drive component to open the left and right compartments and detach them from the porcelain bottle; finally, it drives the displacement adjustment unit 4 to reset, and the operator releases the brake locking mechanism of the universal wheel 12, moves the device to the designated storage area, turns off the equipment power, and completes the cleaning operation.
