Description

Technical Field

[0001] This application relates to the technical field of insulator cleaning devices, and particularly to a microorganism cleaning device for the surface of insulators based on dry ice spraying. Background Art

[0002] As a key component of the power transmission and distribution system, the surface cleanliness of insulators is directly related to the insulation performance and operation safety of power equipment. Long-term exposure to the external environment makes it easy for dust, dirt, and microorganisms to accumulate on the surface of insulators. Especially in high-humidity or highly polluted areas, these pollutants may form conductive paths, leading to serious faults such as partial discharge, flashover, and even insulation breakdown, posing a threat to the stable operation of the power system.

[0003] Currently, the commonly used insulator cleaning methods include high-pressure water spraying and manual cleaning, but both have significant drawbacks. Among them, high-pressure water spraying can achieve a certain cleaning effect, but it has problems such as a large amount of water consumption and may affect the short-term insulation performance of the equipment, making it difficult to implement in water-scarce areas or cold environments; manual cleaning is difficult to adapt to the complex structural characteristics of insulators on high-voltage lines due to low efficiency and high labor intensity, and neither method can effectively solve the problem of deep cleaning of stubborn dirt and microorganisms, making it difficult to meet the actual engineering requirements.

The first driving motor 4 is fixed on the outer side wall of the cleaning tank body 1, and the output shaft of the first driving motor 4 is fixedly connected with the first insulator clamp 6 through the rotating shaft 5. The rotating shaft 5 is rotatably arranged on the side wall of the cleaning tank body 1.

During operation, the first driving motor 4 drives the rotating shaft 5 to rotate, thereby driving the insulator to rotate around its axis and cooperating with the dry ice nozzle 3 to complete the cleaning.

[0064] The dry ice nozzle 3 includes a heating chamber 31 and a nozzle body 32 connected to the outlet end of the heating chamber 31. A heating device for preventing the nozzle orifice from being blocked due to condensation at low temperature is provided in the heating chamber 31, and a pipeline connection port 33 is provided at the inlet end of the heating chamber 31. Specifically, the nozzle body 32 is made of high-strength alloy steel, and the inner wall is coated with ceramic material to improve wear resistance. The outlet diameter of the nozzle body 32 is 20 mm, which can form a uniform and high-speed spray flow, so as to peel off stubborn dirt and microorganisms on the surface of the insulator.

[0065] The heating device includes an electric heating wire spirally wound around the inner wall of the heating chamber 31. Preferably, the heating device further includes a temperature sensor and a temperature control module. The temperature sensor can be fixed to the inner wall of the heating chamber 31 through a threaded interface, insulated from the electric heating wire. The temperature sensor is electrically connected to the temperature control module, and the temperature control module is electrically connected to the electric heating wire. The temperature can be adjusted through an intelligent temperature control system to ensure smooth spraying without affecting the low-temperature performance of the spray.

The first pressure regulating valve, the first flow control valve, the second pressure regulating valve, the second flow control valve and the micro hot film type gas flow velocity sensor are all electrically connected to the control device 12.

[0069] It should be noted that: through the multi-step cleaning method of first blowing the surface dust with compressed air, then cleaning the stubborn dirt with dry ice spray, and finally using compressed air to remove the residual pollutants, there is no need to use water or chemical cleaning agents, which significantly improves the cleaning efficiency and environmental protection. And the device is compactly designed, suitable for on-site rapid deployment and operation, and is especially suitable for the cleaning requirements of insulators on high-voltage transmission lines.

[0070] It is understandable that the control device 12 is used to coordinate the operations of nozzle spraying, nozzle movement, and insulator rotation, ensuring the automation and high efficiency of the cleaning process. Among them, spray control includes adjusting the spraying intensity and speed of compressed air or dry ice spray, and real-time monitoring of the spraying state through a micro hot film type gas flow sensor to ensure the cleaning effect; movement control includes controlling the stepping motor to drive the dry ice nozzle 3 to move along the horizontal slide rail 10 and adjusting the position of the dry ice nozzle 3 to ensure full coverage of the spray coverage; rotation control includes controlling the rotation speed and direction of the first drive motor 4 to ensure the synchronization of the cleaning actions of the insulator and the dry ice nozzle 3.

The intensity and speed of compressed air or dry ice spray are adjusted through the spray control module, the movement position of the dry ice nozzle 3 is adjusted by driving the stepping motor through the movement control module, and the rotation speed and direction of the first drive motor 4 are adjusted through the rotation control module to ensure the automation and high efficiency of the cleaning process.

[0072] The gas filter 14 is composed of multiple layers of filter screens and activated carbon adsorption materials, which can efficiently filter the gas generated by dry ice sublimation and the blown dust, prevent pollutants from spreading with the gas, and ensure the environmental protection of the cleaning process.

[0073] The bottom of the cleaning tank body 1 is provided with an anti-slip base 13. Specifically, the anti-slip base 13 is made of high-strength rubber material, and the surface is designed with grid textures to enhance the friction force, which is used to stabilize the cleaning tank body 1 to prevent the device from shifting or shaking during the cleaning process.

[0074] The material of the cleaning tank body 1 is stainless steel, and the inner wall of the cleaning tank body 1 is coated with a polytetrafluoroethylene coating, which has good corrosion resistance and easy cleaning; the material of the top cover 2 is transparent impact-resistant polycarbonate material (PC).

[0075] It should be noted that: each component jointly completes the efficient cleaning of the insulator surface through reasonable design and precise cooperation. Among them, the cleaning tank body 1 provides a stable operating environment, the anti-slip base 13 and the gas filter 14 ensure the safety and environmental protection of the cleaning process; the dry ice nozzle 3 moves horizontally through the horizontal slide rail 10 and cooperates with the rotating insulator to achieve the efficient removal of surface dirt and microorganisms; the insulator rotation clamping device firmly clamps the insulator and provides rotational power; the control device 12 coordinates the actions of each module to achieve full automation of the cleaning process.

[0076] During specific implementation, the following steps are included:

[0077] 1. Preparation: Before using this device, first confirm the normal working status of each component. Ensure that all connecting pipes and electrical interfaces are undamaged, and the gas source and power supply have been connected. The dry ice supply pipeline should be connected to the dry ice storage device, and ensure that the dry ice storage device is full; the compressed air pipeline should be connected to the compressed air source.

[0078] 2. Install the insulator: Place the insulator to be cleaned in the main body 1 of the cleaning tank. According to the length and specifications of the insulator, adjust the position of the second insulator clamp 8 by moving the sliding shaft 7 to ensure that the first insulator clamp 6 and the second insulator clamp 8 can tightly clamp the two ends of the core rod of the insulator. After the position adjustment of the sliding shaft 7 is completed, it is fixed by the locking component 9, and then the first driving motor 4 drives the rotating shaft 5 to rotate, so that the insulator can rotate around its axis.

[0079] 3. Start the cleaning program: It includes the following steps:

[0080] S1: Dust blowing stage, start the compressed air source, and the dry ice nozzle 3 first blows out a high-pressure air flow onto the surface of the insulator to remove loose dust and impurities on the surface. During this stage, the gas filter screen 14 inside the main body 1 of the cleaning tank plays a filtering role to prevent pollutants from spreading with the air flow.

[0081] S2: Stubborn dirt cleaning stage, start the dry ice spraying mode, and the dry ice nozzle 3 starts to move horizontally along the surface of the insulator while spraying dry ice particles at a high speed. The dry ice particles peel off stubborn dirt and microorganisms on the surface through low temperature and impact force. The heating device ensures the normal temperature of the dry ice nozzle 3 to prevent the nozzle from being blocked due to low temperature and ensure smooth spraying.

[0082] S3: Residue cleaning stage, after the dry ice spraying is completed, start the compressed air source again to blow away the remaining dirt and microorganisms, and use the compressed air to efficiently remove all pollutants in the main body 1 of the cleaning tank, avoiding secondary pollution.

[0083] 4. Cleaning completed: After the cleaning is completed, the first driving motor 4 stops working and the insulator stops rotating. Loosen the second insulator clamp 8 and remove the insulator. The gas filter screen 14 of the main body 1 of the cleaning tank performs a final filtration on the remaining gas to ensure that the gas emission meets the environmental protection requirements.

[0084] 5. Follow-up operations: According to the actual situation inside the main body 1 of the cleaning tank, promptly clean the dirt in the tank to ensure that the device is in good condition for the next use. Regularly check the working conditions of each component to ensure the long-term efficient operation of the device.

[0085] Through the above steps, the insulator surface microbial cleaning device based on dry ice spraying can efficiently, environmentally friendly and safely complete the cleaning work of the insulator surface in a short time, and is particularly suitable for cleaning high-voltage transmission lines or other equipment that is difficult to access.
