Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of insulator cleaning, in particular to a glass insulator cleaning device. BACKGROUND

[0002] The insulator is installed between conductors or conductors and ground components at different potentials, and can withstand voltage and mechanical stress. The insulator has many types, including glass insulators. The glass insulator is made of glass fiber resin and other materials, and has the characteristics of light weight, high strength, corrosion resistance, etc.

[0003] The main function of the glass insulator is to insulate the live line from the ground to prevent current from returning to the ground. However, due to the long-term exposure of the insulator to the outdoor environment, its surface will deposit various pollutants such as industrial dust, smoke particles, and bird droppings. If these pollutants accumulate too much, they will cause the insulator surface to lose its insulating properties, and even cause a flashover trip phenomenon. Therefore, it needs to be cleaned regularly. The traditional cleaning method is for electric power workers to manually clean with a cloth.

[0004] However, the above cleaning method has the problem of low cleaning efficiency. This is because the too smooth surface of the insulator may not be conducive to the attachment and cleaning of dirt, but may increase the risk of flashover. At the same time, the creepage distance of the insulator refers to the shortest distance between two conductive parts measured along its surface. Increasing the creepage distance can increase the flashover voltage of the insulator. Therefore, the surface of the insulator is generally not smooth and flat, which undoubtedly increases the number of cleaning dead angles, and the dead angle positions of each insulator are not the same, thereby ultimately resulting in low manual wiping efficiency.

[0046] The rest of the structure is the same as that of embodiment 3.

[0047] The working principle of the application is as follows:

[0048] The insulator cleaning process is as follows:

[0049] First, two cleaning sponges 22 are arranged on both sides of the insulator, and then the distance between the two cleaning sponges 22 is adjusted to ensure that the two cleaning sponges 22 can be attached to both sides of the insulator by the shapeable feature of the cleaning sponges 22, so that the basic premise of effectively cleaning different cleaning dead angles and different specifications of insulators is provided;

[0050] The adjustment steps of the two cleaning sponges 22 are as follows: rotating the knob 17 drives the first lead screw 11 to rotate, thereby forcing the first nut seat 13 to move linearly close to the second nut seat 14; with the rotation of the first lead screw 11, the transmission wheel 15 on the first lead screw 11 rotates, and the other transmission wheel 15 is driven to rotate synchronously by the transmission belt 16; since the other transmission wheel 15 is sleeved on the second lead screw 12, the second lead screw 12 will rotate synchronously and in the same direction as the first lead screw 11, but since the thread directions of the two lead screws are opposite, the second nut seat 14 will be forced to move linearly close to the first nut seat 13, and finally the mutual approach of the two moving seats 2 is realized; reversing the rotation of the knob 17 will make the two moving seats 2 move away from each other.

[0051] When the cleaning sponges 22 are attached to both sides of the insulator, the air cylinder 31 is held with the center of the insulator as the center, and the mounting seat 1 and the two cleaning sponges 22 are rotated, so that the left and right cleaning sponges 22 can simultaneously clean the surfaces of the left and right sides of the insulator, which has the characteristics of no dead angle and small workload compared with the traditional cleaning by electric power workers.

[0052] The self-cleaning process of the cleaning sponge 22 is as follows:

[0053] When the previous insulator is cleaned, rotate the knob 17 in the opposite direction to increase the distance between the two moving seats 2, so that the two cleaning sponges 22 no longer press against the surfaces of the insulator, and the two cleaning sponges 22 will recover the deformation. At this time, the electrician can take the device as a whole from the previous insulator and observe the cleaning degree of the surface of the cleaning sponge 22 to determine whether to clean the next insulator directly. If the cleaning degree of the cleaning sponge 22 is poor, the cleaning sponge 22 can be cleaned. The specific process is as follows:

[0054] First, the electrician holds the air cylinder 31 with one hand and pushes the piston tube 36 downward with the other hand. At this time, the piston sheet 37 gradually presses the inner cavity space of the air cylinder 31, and the cleaning head 39 connected to the bottom of the piston tube 36 moves downward synchronously, so that the scraper 313 is driven to approach and roll on both sides of the cleaning sponge 22, starting to scrape the dust and impurities on the surface of the cleaning sponge 22. After the air in the air cylinder 31 is pressed, it is uniformly introduced into the piston tube 36 through the first air exhaust hole 38, then passes through the cleaning head 39, the mounting block 310, and enters the rotating tube 311, and is discharged through the second air exhaust hole 312 on the surface of the rotating tube 311. The airflow discharged guides the dust and impurities into the dust suction hole 23 around the cleaning sponge 22, completing a cleaning;

[0055] Finally, when the stop sheet on the piston tube 36 descends to the state of abutting against the top of the air cylinder 31, the left and right side scrapers 313 have just completed the cleaning of the bottom of the cleaning sponge 22. At this time, the electrician pulls the piston tube 36 upward, and the left and right side scrapers 313 return to the original position and roll on the surface of the cleaning sponge 22 again. With the rising of the piston tube 36, the piston sheet 37 installed on the piston tube 36 and located in the piston cavity 32 rises synchronously. At this time, the space of the piston cavity 32 below the piston sheet 37 gradually increases, so the pressure decreases. At this time, the air in the dust suction hole 23 is extracted through the suction tube 35, so as to further guide the dust and impurities into the storage cavity 21, and after being filtered by the collection filter box 24, it is supplemented into the piston cavity 32;

[0056] Special note: through the reciprocating sliding of the piston tube 36, the dust and impurities scraped off from the cleaning sponge 22 can be guided into the filter collection box through the airflow, and the whole process does not require any electrical equipment, which not only reduces the gravity of the whole device, but also avoids the anxiety of battery life, and is suitable for electricians to use continuously for a long time in the air. Compared with traditional manual wiping, it has the advantages of no dead angle and high wiping efficiency.

[0057] The above merely provides the preferred embodiment of the application, and cannot allude the protection scope of the application, therefore any equivalent changes made according to the claims of the application shall be within the scope of the application.
