Description

Technical Field

[0001] This utility model relates to the field of high-voltage bushing cleaning technology in the switchgear area of ​​power plants and substations, and particularly to a high-voltage bushing cleaning device. Background Technology

[0002] High-voltage bushings within the gantry area of ​​power plants and substations include outgoing line bushings, surge arrester bushings, and voltage transformer bushings. Under long-term outdoor operating conditions, dust and debris accumulate on the bushing surface, directly leading to increased leakage current and affecting the normal operation of the equipment. Therefore, regular maintenance and cleaning are necessary.

[0003] The traditional cleaning process involves manually wiping each sleeve individually, which includes five steps: preparation, cutting a cloth to the appropriate size for cleaning, secondary cleaning, and final acceptance.

[0004] Statistics show that traditional cleaning of a single-phase bushing of a single piece of equipment takes more than 20 minutes, and cleaning multiple bushings takes even longer. During the cleaning process, each bushing skirt needs to be thoroughly cleaned. However, because maintenance personnel need to work at heights and for extended periods, their energy is limited, leading to problems such as missed areas, low cleaning quality, and low efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure bushing cleaning device to solve problems such as missed cleaning of the bushing skirt, low cleaning quality and efficiency during the high-pressure bushing wiping process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-pressure bushing cleaning device includes a stress spring, with arc-shaped outer shells connected to both sides of the stress spring. Each arc-shaped outer shell has an electric rotating shaft and a rotating shaft at both ends on its inner side. An elastic velvet belt is fitted on the electric rotating shaft and the rotating shaft. The electric rotating shaft is connected to a universal joint, and the universal joint is connected to a motor.

[0008] In some embodiments, the number of stress springs is two, and they are arranged vertically.

[0009] In some embodiments, the motor is connected to a battery.

[0010] In some embodiments, the battery is disposed at the upper end of the motor.

[0011] In some embodiments, each of the curved housings is provided with a handle.

[0012] In some embodiments, the two handles are arranged symmetrically.

[0013] In some embodiments, a start switch is provided on the motor housing.

[0014] In some embodiments, bearings are provided at both ends of the electric rotating shaft.

[0015] In some embodiments, bearings are provided at both ends of the rotating shaft.

[0016] In some embodiments, the bottom of the electric rotating shaft is connected to the output end of the motor via the universal joint.

[0017] Compared with the prior art, the high-pressure bushing cleaning device provided by this utility model has the following beneficial effects:

[0018] This invention features a simple structure and convenient operation. The compressive force exerted by the stress spring on the inner side of the arc-shaped outer shell ensures a tight fit between the elastic fleece strip and the sleeve skirt. An electric rotating shaft and a drive shaft rotate the elastic fleece strip, enabling automatic cleaning of specific sections of the sleeve. This eliminates the tedious step of wiping each sleeve skirt individually, removes the risk of missed areas, improves cleaning efficiency, shortens cleaning time, and reduces the wiping pressure on workers, greatly facilitating sleeve cleaning.

[0024] The following detailed description provides further details on specific implementation methods.

[0025] like Figure 1 and Figure 2 As shown, this utility model provides a high-pressure bushing cleaning device, including a stress spring 1, an electric rotating shaft 2, a rotating shaft 3, an arc-shaped outer shell 4, a battery 6, a bearing 7, a motor 8, and a universal joint 10.

[0026] The stress spring 1 is connected to two arc-shaped outer shells 4 at both ends. The two arc-shaped outer shells 4 are symmetrically arranged, and each arc-shaped outer shell 4 has an electric rotating shaft 2 and a rotating shaft 3 on its inner side. The electric rotating shaft 2 is located at the end of the inner side of the arc-shaped outer shell 4 closest to the stress spring 1, and the rotating shaft 3 is located at the other end of the inner side of the arc-shaped outer shell 4 away from the stress spring 1. The connection between the stress spring 1 and the arc-shaped outer shell 4 is secure and reliable, and anti-loosening and anti-detachment measures are provided.

[0027] There are two stress springs 1 arranged vertically. Two arc-shaped outer shells 4 are set on the left and right sides of the two vertically arranged stress springs 1.

[0028] Both ends of the electric rotating shaft 2 and the rotating shaft 3 are equipped with bearings 7. The rotating shaft 3 can rotate freely. The bottom of the electric rotating shaft 2 is connected to the output end of the motor 8 via a universal joint 10. The battery 6 is electrically connected to the motor 8, and the start switch 9 is electrically connected to the motor 8 and is mounted on the motor 8.

[0029] Optionally, battery 6 is configured as a rechargeable battery.

[0030] Fit elastic fleece strips onto the left-side electric rotating shafts 2 and 3, and also fit them onto the right-side electric rotating shafts 2 and 3. The two elastic fleece strips should be arranged symmetrically, meaning their length and tension should be roughly the same, for ease of use and to prevent inconsistent cleaning results on both sides.

[0031] Motor 8 drives universal joint 10 to rotate, and universal joint 10 drives electric rotating shaft 2 to rotate, thereby driving the elastic fleece belt to move on electric rotating shaft 2 and rotating shaft 3.

[0032] Optionally, anti-slip measures may be provided on the electric rotating shaft 2 and the rotating shaft 3.

[0033] The direction of rotation of the elastic fleece belt should be: counterclockwise on the left side and clockwise on the right side, or clockwise on the left side and counterclockwise on the right side.

[0034] Optionally, a battery 6 may be installed on the upper end of the motor 8.

[0035] Optionally, a handle 5 is provided on the arc-shaped housing 4 of the battery 6 on the side away from the stress spring 1. Each arc-shaped housing 4 is provided with a handle 5, and the two handles 5 are arranged symmetrically.

[0036] Optionally, a start switch 9 is provided on the upper side of the housing of the right motor 8.

[0037] When cleaning the high-pressure bushing, an elastic velvet strip is fitted between the electric rotating shaft 2 and the rotating shaft 3 on both sides of the stress spring 1. When the start switch 9 is turned on to start the motor 8, the elastic velvet strip rotates continuously between the electric rotating shaft 2 and the rotating shaft 3. By opening the arc-shaped outer shell 4 with the handle 5, the device is fitted onto the high-pressure bushing. The recoil force of the stress spring 1 causes the elastic velvet strip to fill the gap of the bushing skirt.

[0038] The steps for using the high-pressure bushing cleaning device provided by this utility model are as follows:

[0039] Step 1: Confirm that the battery has sufficient power;

[0040] Step 2: Fit elastic velvet strips onto the electric rotating shaft 2 and rotating shaft 3 on both sides of the arc-shaped outer shell 4 respectively;

[0041] Step 3: Turn on the start switch 9;

[0042] Step 4: Use handle 5 to open the two curved outer shells 4, and press the elastic velvet strip inside the device tightly onto the high-pressure bushing to be cleaned to begin cleaning;

[0043] Step 5: After cleaning the sleeve in this area, use the handle 5 to pry open the two curved outer shells 4 and remove the device;

[0044] Step 6: Repeat steps 4 and 5 until the cannula cleaning task is completed, then turn off the start switch.

[0045] Therefore, this utility model provides a high-pressure sleeve cleaning device with a simple structure that can reduce the number of missed wipes on the high-pressure sleeve skirt, shorten the cleaning time, and improve the cleaning quality.

[0046] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
