Description

Technical Field

[0001] The present invention relates to the technical field of lightning arresters, and in particular to a lightning arrester with an automatic cleaning function. Background Art

[0002] A lightning arrester is a device used to protect electrical equipment from lightning overvoltage and operating overvoltage. It protects the equipment from damage by providing a low-impedance path to direct the overvoltage to the ground. The working principle of the lightning arrester is based on the characteristics of the internal nonlinear resistor material. Under normal circumstances, it has a very high resistance and is almost non-conductive, but in the event of an overvoltage, the resistance will drop rapidly, allowing large currents to pass and reducing the overvoltage to a safe level. The lightning arrester will produce a large amount of dust accumulation when working stably in an outdoor environment for a long time, which needs to be handled regularly to avoid affecting the performance of the lightning arrester.

[0003] In the existing patent CN220716899U, a self-cleaning arrester for photovoltaic substation engineering is disclosed, including a bottom plate, one side of the bottom plate is fixedly connected with a motor box, and the top surface of the motor box is threadedly connected with a threaded fastener. The advantage of the utility model is that the staff places the arrester on the motor box and fixes it on the motor box with a threaded fastener, then puts the cleaning frame on the porcelain sleeve, and fixes the limit cover on the porcelain sleeve through a threaded column. After the cleaning device is installed, the staff needs to turn on the motor to drive the driving gear to rotate, and the driven gear can be driven to rotate through the meshing transmission, and then the cleaning frame can be driven to rotate. The dust accumulated on the arrester can be cleaned by the cleaning strip, and the workers do not need to climb to a high place to clean it, which can not only save the labor of the workers, but also reduce the safety hazards caused by cleaning the arrester.

[0004] In the above structure, the effect of automatic cleaning of the lightning arrester can be achieved, but when cleaning is required, each layer of the lightning arrester must be processed at the same time, which makes it difficult to achieve targeted cleaning. This can easily lead to damage to the outer shell of the lightning arrester due to excessive cleaning, thereby reducing the service life of the lightning arrester. When the lightning arrester does not need to be cleaned, the cleaning device is always in contact with the lightning arrester and cannot be separated from the lightning arrester, which can easily lead to a decrease in the performance of the lightning arrester, reduce the safety of the lightning arrester, and reduce the overall control ability of the device.

[0045] Start the air pump 901, open the solenoid valve 903, and through the action of the air charging tube 902, the air pump 901 delivers the gas to the delivery hard tube 1001 and the arc tube 703, and through the action of the delivery hose 1002 and the delivery hard tube 1001, the gas is delivered to each arc tube 703, and the inflation airbag 801 is inflated through the inflation nozzle 1003. At this time, the inflation airbag 801 expands until the surfaces of the gap between the cleaning strip 802 and the arrester body 2 are tightly fitted, so that the cleaning airbag and the cleaning strip 802 surround the arrester body 2 in a circle. At this time, the cleaning airbag and the cleaning strip 802 are located on the inner side of the arrester body 2, forcing the cleaning strip 802 to contact the arrester body 2 without dead angles;

[0046] During overall cleaning, the drive motor 401 is started, and the output shaft of the drive motor 401 rotates to drive the drive gear 402 to rotate, and the drive gear 402 rotates to drive the rotating gear ring 403 to rotate, so that the rotating disk 301 rotates, and the rotating disk 301 rotates to drive the vertical reinforcing ribs 1101 and the horizontal reinforcing ribs 1102 and the support rod 302 to rotate synchronously, and the support rod 302 drives the support ring 303 to rotate, and the support ring 303 forces the adjustment component 5, the transmission component 6, the pulling component 7, the cleaning component 8, the conveying component 10 and the inflation component 9 to rotate synchronously, so that the cleaning strip 802 rotates to clean the surface of the arrester body 2, so as to achieve the overall cleaning effect of the cleaning strip 802 on the dust on the surface of the arrester body 2;

At this time, since the other expansion airbags 801 and the cleaning strip 802 are located on the outside of the lightning arrester body 2, during the rotation process, the other expansion airbags 801 and the cleaning strip 802 are away from the lightning arrester body 2 and form an annular sealed space, thereby effectively preventing the cleaned dust from crossing into the gaps of other lightning arrester bodies 2, thereby improving the cleaning effect.

[0050] This solution has the characteristics of multifunctional control. On the one hand, it can achieve the effect of overall cleaning of the lightning arrester body 2 and improve the cleaning efficiency; on the other hand, when cleaning is not needed, the expansion airbag 801 and the cleaning strip 802 can be kept away from the lightning arrester body 2 to ensure the normal operation of the lightning arrester body 2, improve the performance of the lightning arrester body 2, and make the expansion airbag 801 and the cleaning strip 802 form a sealed environment with the lightning arrester body 2, effectively blocking dust from entering the gap of the lightning arrester body 2, and solving the problem of dust accumulation from the source; on the other hand, during targeted cleaning, the effect of targeted cleaning of the gap of the lightning arrester body 2 is achieved to avoid excessive cleaning, while ensuring that the gaps of other lightning arrester bodies 2 are not affected, avoiding cross-accumulation of dust, improving the cleaning effect, and increasing the service life of the lightning arrester.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
