Description

Technical Field

[0001] This utility model belongs to the technical field of insulator cleaning devices, specifically, it relates to a power transmission and transformation insulator cleaning device. Background Technology

[0002] In power systems, transmission and transformation insulators are key components that ensure the insulation performance of power equipment, and their operating status directly affects the safety of the power grid. With the continuous increase in the demand for power transmission, insulators are exposed to complex outdoor environments for a long time, making them susceptible to corrosion from industrial dust, salt crystals, bird droppings, and other contaminants, which leads to a decline in insulation performance and causes faults such as flashover tripping due to pollution.

[0003] Existing insulator cleaning technologies mainly include high-pressure water washing, dry ice cleaning, and mechanical wiping. While high-pressure water washing can effectively remove stubborn stains, it suffers from problems such as high water consumption, wastewater pollution, and potential freezing of the insulator surface in low-temperature environments. Dry ice cleaning requires specialized equipment, is costly, and is ineffective at cleaning dirt in tiny crevices. Traditional mechanical wiping equipment often uses a single brush or cloth strip for cleaning, which suffers from insufficient coverage and low cleaning efficiency for the underside of insulator skirts and complex structures. Therefore, a power transmission and transformation insulator cleaning device is proposed. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0029] Example: Refer to Figures 1-7A power transmission and transformation insulator cleaning device includes: an installation arm 1 with connecting arms 11 installed at both ends; a first support arm 13 and a second support arm 14, respectively installed on one end of the connecting arm 11, with a second rotating drum 131 and a third rotating drum 141 rotatably connected to the first support arm 13 and the second support arm 14, respectively; a first rotating drum 111, rotatably connected to one end of the installation arm 1, with the first rotating drum 111, the second rotating drum 131, and the third rotating drum 141 forming a triangle; and a wiping belt 2 connected to the first rotating drum 111, the second rotating drum 131, and the third rotating drum 141, the wiping belt 2 having an L-shaped cross-section for contacting the bottom surface of the insulator skirt.

[0030] Support arms 13 and 14 are rotatably connected to connecting arm 11. Support arms 13 and 14 are connected by elastic sheet 15 and pull on each other to ensure the stability of their relative positions. Two limiting rods 16 are symmetrically fixedly connected to connecting arm 11, and fixing blocks 161 are symmetrically fixedly connected to support arms 13 and 14. The limiting rods 16 and fixing blocks 161 correspond to each other. The limiting rods 16 are symmetrically fixed to connecting arm 11, and the fixing blocks 161 are fixedly connected to corresponding positions on support arms 13 and 14. When the support arms rotate to a suitable angle, the limiting rods 16 and fixing blocks 161 cooperate to limit the support arms 13 and 14 and prevent them from rotating excessively.

[0031] The inner wall of the wiping belt 2 is provided with teeth, and the outer circumference of the rotating drum 111, rotating drum 2 131 and rotating drum 3 141 is provided with grooves. The teeth and grooves mesh with each other to ensure that the wiping belt 2 will not slip during rotation.

[0032] A motor 4 is installed on the connecting arm 11. A sprocket 41 is installed on the output end of the motor 4 and on the rotating drum 111. The two sprockets 41 are connected by a chain, so that the motor 4 can drive the rotating drum 111 to rotate, thereby driving the wiping belt 2 to rotate in a cycle. The motor 4 is located in the interlayer of the connecting arm 11, which can also be used to improve the strength of the connecting arm 11.

[0033] The connecting arm 11 is fixedly connected to the mounting arm 1 or the connecting arm 11 is rotatably connected to the mounting arm 1 via the torsion spring 12; to adapt to different operating scenarios, when the insulator diameter is large, a design with a torsion spring 12 can be adopted so that the connecting arm 11 can be adapted to the diameter of the insulator.

[0034] The wiping strip 2 consists of a vertical strip 20 and a horizontal strip 24. Wiping strips 21 are set on the outer periphery of the vertical strip 20. Multiple accumulation grooves 22 are evenly spaced on the wiping strips 21, and oblique guide grooves 23 are set on both sides. Grooves 25 are set on the upper surface of the horizontal strip 24 to improve the cleaning effect and collect dirt. When the wiping strip 2 wipes and cleans the surface of the insulator, some dirt will accumulate in the accumulation grooves 22, and the oblique guide grooves 23 can guide the wiped dirt into the accumulation grooves 22.

[0035] An mounting plate 31 is installed on the connecting arm 11, and a scraper 3 is installed on the mounting plate 31. The side scraping teeth 32 on the side of the scraper 3 correspond to the accumulation groove 22, and the bottom scraping teeth 33 correspond to the groove 25. The scraper 3 is used to clean the dirt from the accumulation groove 22 and the groove 25 by using the side scraping teeth 32 and the bottom scraping teeth 33 when the wiping belt 2 rotates and passes through the scraper 3.

[0036] In one embodiment, the scraper 3 is made of polyethylene or polyethylene with polytetrafluoroethylene on its surface, which has good wear resistance and flexibility, and can protect the wiping belt 2 to the maximum extent while ensuring the removal of stains.

[0037] In one embodiment, the wiping strip 2 is made of rubber-coated nylon canvas, which has good abrasion resistance, flexibility and insulation.

[0038] The mounting arm 1 is equipped with a connector 10, which has an internal thread. A connecting rod 101 is threaded onto the connector 10, which allows for easy installation of the connecting rod 101 according to the cleaning height, thus meeting the cleaning needs of insulators at different heights.

[0039] When using this device, the operator holds the connecting rod 101 and places the wiping strips 2 on both sides of the insulator. The wiping strips 2 are made to adhere to the surface of the insulator by the rotational connection between the support arm 13, the support arm 2 14 and the connecting arm 11, as well as the action of the elastic sheet 15. If the connecting arm 11 is rotatably connected to the mounting arm 1 through the torsion spring 12, the adhesion between the wiping strips 2 and the insulator can be further adaptively adjusted.

[0040] Extend the cable of motor 4 to the connecting rod 101, turn on motor 4 through the controller on the cable, and motor 4 drives the rotating drum 111 to rotate through sprocket 41 and chain, thereby driving the wiping belt 2 to circulate along the triangular path (it should be understood that the two wiping belts 2 are controlled by two independent motors 4 to rotate relative to each other).

[0041] The L-shaped cross-section design of the wiping strip 2 allows the vertical strip 20 to fit against the side of the insulator, and the horizontal strip 24 to contact the bottom surface of the insulator skirt, achieving efficient wiping. During the wiping process, the inclined guide groove 23 on the wiping strip 21 guides the dirt to the accumulation groove 22, while the groove 25 on the horizontal strip 24 collects the dirt from the bottom surface of the skirt.

[0042] As the wiping belt 2 rotates, when the accumulation groove 22 and the groove 25 pass through the scraper 3, the side scraping teeth 32 on the side of the scraper 3 scrape away the dirt in the accumulation groove 22, and the bottom scraping teeth 33 clean the dirt in the groove 25, ensuring that the wiping belt 2 remains clean and maintains a high-efficiency cleaning effect.

[0043] Continue running the device until the dirt on the surface of the insulator and the bottom of the skirt is cleaned. Then turn off motor 4, remove the device, and the cleaning work is complete.

[0044] During the cleaning process, an additional water spray hose can be used. When the insulator is at a high height, the front end of the device has a certain weight due to the setting of motor 4. Therefore, when cleaning higher insulators, a rope can be connected to an additional extension rod, and the other end of the rope can be connected to the connecting rod 101 near the mounting arm 1. The extension rod is used to assist the front end of the device and improve stability.

[0045] Figure 7 For existing insulators, this device features an L-shaped wiping strip design, making it particularly suitable for applications such as... Figure 7 The insulator shown can better improve the cleaning effect.

[0046] This utility model uses rotating drum 111, rotating drum 231, and rotating drum 311 to form a triangle and drive the L-shaped cross-section wiping belt 2 to rotate, which can wipe the side of the insulator and the bottom of the insulator skirt at the same time. Compared with traditional equipment that cleans in one direction, it effectively reduces cleaning dead angles and greatly improves cleaning effect.

[0047] Support arm 13 and support arm 2 14 are connected by elastic sheet 15 and can rotate. The connecting arm 11 and the mounting arm 1 can be rotated, so that the device can automatically adjust the fit according to the size and shape of the insulator, adapt to different specifications of power transmission and transformation insulators, and enhance the versatility and applicability of the device.

[0048] The accumulation groove 22, inclined guide groove 23, and groove 25 on the wiping belt 2 cooperate with the side scraping teeth 32 and lower scraping teeth 33 of the scraper 3 to realize the automatic cleaning of the wiping belt 2 in the process of cleaning the insulator, reduce the secondary pollution of the insulator by dirt, and at the same time reduce the frequency of manual cleaning of the wiping belt 2, thus improving the overall work efficiency. The motor 4 is installed in the interlayer of the connecting arm 11. The wiping belt 2 and the rotating drum 111, rotating drum 2131, and rotating drum 3141 are driven by tooth and groove meshing. The overall structure is compact and occupies little space. The triangular rotating drum structure and limit design ensure the stability of the device during operation and reduce the problem of poor cleaning effect caused by shaking.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
