Description

Technical Field

[0002] As an important node for electric energy transmission and distribution, the safe and stable operation of the substation is crucial to the reliability of the entire power grid. The electrical equipment in the substation, especially the insulator, is a key component to ensure the electrical isolation between the live part and the grounded part of the electrical equipment. The insulation performance of the electrical equipment directly affects the safe operation of the electrical equipment. In the actual operation process, foreign objects such as dirt and snow are often attached to the surface of the insulator. If the snow is not removed in time, the snow will melt and then freeze to form icicles. These foreign objects will affect the insulation performance of the insulator to varying degrees, which may cause the insulation performance of the insulator to decline, thereby increasing the risk of flashover accidents in the equipment. The insulator cleaning device in the prior art has the problem of incomplete cleaning. During the cleaning process, it is not convenient to make foreign objects such as dirt and snow on the insulator fall off the insulator, and there are still large cleaning dead corners after cleaning.

[0019] The technical scheme and technical effects of the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0020] Please see Figure 1 and Figure 2The utility model provides a fast-deployed substation safety measure device, including a cleaning part 1, an adjusting part 2, and a gas transport device 3. The cleaning part 1 is composed of an air pipe 101 and a nozzle 102. The air pipe 101 is a semicircular ring structure. A plurality of nozzles 102 are evenly spaced along the circumference of the air pipe 101. The nozzles 102 are inclined at a predetermined angle. An arc-shaped air inlet pipe 103 is fixedly provided on one side of the air pipe 101. The end of the arc-shaped air inlet pipe 103 is connected to the adjusting part 2. The gas transport device 3 is provided below the adjusting part 2. The adjusting part 2 and the gas transport device 3 are connected through an equipment adapter 4.

[0021] Furthermore, in order to improve the cleaning effect of the insulator, the nozzle 102 is flat and gradually becomes thinner along the direction of gas ejection. The gas is accelerated at the nozzle 102 and forms a shear-type airflow, which causes dirt or snow on the insulator to fall off, thereby improving the cleaning effect of the insulator.

[0022] Furthermore, in order to facilitate the disassembly of the cleaning device, the end of the arc-shaped air inlet pipe 103 is connected to the adjustment part 2 via a thread, and the end of the adjustment part 2 is connected to the equipment adapter 4 via a thread.

[0023] Furthermore, in order to facilitate the staff to move the cleaning part 1 during the cleaning process, the equipment adapter 4 and the gas transport device 3 are connected by a hose 5, and the equipment adapter 4 and the hose 5 are connected by threads.

[0024] Furthermore, in order to facilitate the cleaning of dirt or snow on high insulators, the adjustment part 2 is composed of at least one air guide tube, and two or more air guide tubes are connected by threads. The number of air guide tubes of the adjustment part 2 is set according to the needs of the staff to adjust the height of the cleaning part.

[0025] Furthermore, in order to improve the insulation performance of the equipment, the air guide tube is made of epoxy resin, which has high insulation properties.

[0026] Furthermore, in order to facilitate the removal of dirt or snow on the insulator, the nozzle 102 is predetermined to be inclined at an angle of 1° to 179° along the horizontal direction, and the ejected high-speed airflow can generate shear force on the dirt or snow on the insulator to facilitate the removal of the dirt or snow.

[0027] Furthermore, in order to clean the ice on the insulator, a heating device 6 is provided between the gas transport device 3 and the equipment adapter 4. The heating device 6 is connected to the hose 5 by threads, and the heating device 6 is used to heat the gas transported by the gas transport device 3.

[0028] In this embodiment, the gas transport device 3 uses an air pump. When cleaning the insulator, the staff first connects the arc-shaped air inlet pipe 103 and the air guide pipe of the adjustment part 2 through threads, and then chooses to use several air guide pipes according to the needs of the staff. In this embodiment, two air guide pipes are selected, and the second air guide pipe is connected to the rear of the first air guide pipe. The two air guide pipes are connected together through threads, and the equipment adapter 4 is connected to the end of the second air guide pipe. After the gas transport device 3 and the equipment adapter 4 are connected through the hose 5, the gas transport device 3 is started, and the staff can clean the insulator by holding the air guide pipe. An arc-shaped air inlet pipe 103 is fixedly provided on one side of the cleaning part 1, so that when the air guide pipe is lifted, the semi-annular structure of the air pipe 101 is just close to the cylindrical insulator After the air in the air guide tube enters the air pipe 101, it is sprayed out from the nozzle 102 on the air pipe 101 to clean the dirt or snow on the insulator. The nozzle 102 is inclined by 1° to 179° in the horizontal direction. In order to generate shear force on the dirt or snow on the insulator during the cleaning process, the high-speed airflow sprayed by the nozzle 102 is convenient for the dirt or snow on the insulator to fall off the insulator, thereby improving the cleaning effect. The device has a simple structure and a light lifting part, which can greatly reduce the difficulty of operation for the staff. When ice is formed on the insulator, the heater 6 is started to heat the air, so that the nozzle 102 sprays hot air to eliminate the ice on the insulator. After the cleaning is completed, the cleaning part 1, the air guide tube, and the equipment adapter 4 are removed in turn. The device is easy to disassemble and assemble, and can be quickly assembled during use to improve work efficiency.

A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
