Description

Technical Field

[0001] This invention relates to the field of insulator technology, specifically to an insulator cleaning device and its usage method. Background Technology

[0002] Insulators are a crucial component of power systems. Their primary function is to support and insulate conductors, ensuring the safe transmission of current. However, over time, contaminants accumulate on the surface of insulators, which can lead to a range of problems that affect the stability and safety of the power system.

[0003] Insulators exposed to outdoor environments easily absorb pollutants from the air, such as dust, salt, and other chemicals. In humid weather, these pollutants absorb moisture, forming a conductive layer that reduces the insulator's insulation performance. When the voltage exceeds a certain threshold, flashover may occur on the insulator surface, i.e., discharge along the air gaps on the insulator surface. This flashover can not only cause line tripping and power outages but may also trigger larger power grid accidents, resulting in widespread power outages and losses.

[0004] In existing technologies, to avoid the need for manual cleaning of insulators periodically, cleaning methods involve spraying cleaning agents onto the insulator surface using a nozzle. While this method can clean insulators, it inevitably has shortcomings in practical use. Manual operation is easily affected by the metal frame of on-site power auxiliary equipment, making it inconvenient to clean the insulators comprehensively. Furthermore, continuously holding the nozzle manually increases the labor load. Therefore, an insulator cleaning device and its usage method are proposed to solve the existing problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an insulator cleaning device and its usage method, which solves the problems of manual cleaning, high labor load, and the fact that the nozzle is easily blocked by the installation frame, resulting in an excessively long nozzle that is inconvenient for comprehensive cleaning of the insulator.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an insulator cleaning device, comprising a water tank and a toothed rotating cover, wherein the toothed rotating cover is rotatably mounted on the top of the water tank via a sealed bearing, and a plurality of ear plates are fixedly connected at equal intervals around the surface of the water tank, a cleaning mechanism is provided on the top of the toothed rotating cover, a flexible shielding mechanism is provided on the top of the toothed rotating cover in conjunction with the cleaning mechanism, and a self-cleaning mechanism is provided on the top of the water tank.

[0007] Preferably, the cleaning mechanism includes a spray pipe connected to the top of the toothed rotating cover, and two spray pipes are symmetrically arranged. Several nozzles are connected to the surface of the spray pipe. Sliding frames are fixedly connected to both sides of the top of the toothed rotating cover. Sliding blocks are slidably connected inside the sliding frames. A circular plate is fixedly connected to the top of the sliding blocks. An installation shaft is rotatably arranged on the top of the circular plate. A brush sleeve is installed on the surface of the installation shaft. A drive motor is fixedly connected to the front side of the water tank through a bracket. A first gear that meshes with the toothed rotating cover is installed on the output shaft of the drive motor.

[0008] Preferably, the flexible shielding mechanism includes a shielding cylinder, which is rotatably mounted on the top of the toothed rotating cover, and two shielding cylinders are symmetrically arranged. A second gear is fixedly connected to the surface of the shielding cylinder, and a toothed plate that meshes with the second gear is fixedly connected to the surface of the sliding block. The surface of the sliding frame is provided with a movable groove that matches the toothed plate.

[0009] Preferably, the self-cleaning mechanism includes a gear ring, which is fixedly mounted on the top of the water tank by a bracket. A third gear that meshes with the gear ring is fixedly connected to the surface of the mounting shaft. A conical cover is fixedly connected to the top of the toothed rotating cover by a bracket. Both sides of the top of the conical cover are connected to movable frames that are used in conjunction with the mounting shaft. A stop bar that is used in conjunction with the brush sleeve is fixedly connected to the front side of the movable frame.

[0010] Preferably, a limiting sleeve is fixedly connected to the top of the circular plate, and two limiting sleeves are symmetrically arranged. A limiting rod is slidably connected inside the limiting sleeve. A return spring is fixedly connected between the limiting rod and the limiting sleeve. A number of limiting grooves that are used in conjunction with the limiting rod are equidistantly opened around the bottom of the third gear.

[0011] Preferably, an electric telescopic rod is fixedly connected inside the sliding frame, and the extended end of the electric telescopic rod is fixedly connected to the side of the sliding block.

[0012] Preferably, the cone-shaped cover has openings on both the front and rear sides of its top.

[0013] Preferably, the front side of the water storage tank is connected to an inlet pipe.

[0014] This invention also discloses a method for using an insulator cleaning device, specifically including the following steps: S1. Equipment installation: The water storage tank is pre-installed on the transformer using bolts and lugs, then the insulators are passed through the water storage tank and then connected to the transformer. S2. Regular Cleaning: Connect the on-site delivery pump pipeline to the inlet pipe in advance, then start the delivery pump to deliver cleaning agent into the water storage tank. The cleaning agent is sent into the spray pipe through the water storage tank and the toothed rotating cover, and then sprayed out through the nozzle. Then, remotely start the electric telescopic rod and drive motor. The electric telescopic rod starts its extension end to drive the sliding block, circular plate, mounting shaft and brush sleeve to move until the third gear on the surface of the mounting shaft meshes with the gear ring on the top of the water storage tank. When the drive motor starts, the drive motor drives the first gear to mesh with the toothed rotating cover, causing the toothed rotating cover to drive the spray pipe, mounting shaft and brush sleeve to move circumferentially. The circumferential movement of the spray pipe, mounting shaft and brush sleeve will spray and clean the insulator circumferentially. S3, Self-detachment of shield: When the extension end of the electric telescopic rod drives the sliding block to move, the sliding block synchronously drives the toothed plate to mesh with the second gear. The meshing of the toothed plate with the second gear will drive the shielding cylinder to rotate. When the mounting shaft moves to mesh with the third gear and the gear ring, the corresponding shielding cylinder will rotate to detach from the shielding of the nozzle and expose the nozzle nozzle. S4. Impurity Removal: When the mounting shaft and brush sleeve move in a circular motion, the third gear on the surface of the mounting shaft meshes synchronously with the gear ring, causing the mounting shaft to drive the brush sleeve to rotate while moving in a circular motion, thus strengthening the cleaning. The brush sleeve, along with the rotation of the mounting shaft, will continuously beat the stop bar, causing the impurities attached to the surface of the brush sleeve to be removed by beating.

[0015] Beneficial effects This invention provides an insulator cleaning device and its method of use. Compared with existing technologies, it has the following advantages: (1) The insulator cleaning equipment and its usage method, by setting a cleaning mechanism, a flexible shielding mechanism and a self-cleaning mechanism between the water storage tank and the toothed rotating cover, enables the device to be installed in a fixed manner and remotely controlled automatically, thereby making it easy for the insulator to be automatically flushed and cleaned on a regular basis, reducing operational inconvenience and labor load, and simultaneously removing the attached impurities from the brush sleeve during cleaning, and automatically switching the shielding state and detachment state of the spray pipe and nozzle during cleaning.

[0016] (2) The insulator cleaning device and its usage method, by setting an electric telescopic rod between the sliding block and the sliding groove frame, makes it easy for the mounting shaft and brush sleeve to be reset and thus disengaged from the insulator.

[0017] (3) The insulator cleaning device and its usage method, by setting a limiting sleeve, a limiting rod, a reset spring and a limiting groove between the third gear and the circular plate, can automatically limit the third gear after it is disengaged from the gear ring, thereby avoiding the problem of the third gear and the gear ring being inconvenient to mesh and be calibrated in the future due to arbitrary rotation.

[0018] (4) The insulator cleaning device and its usage method are provided with a conical cover on the top of the toothed rotating cover, so that the conical cover can receive the removed impurities and protect the lower device. The conical cover and the toothed rotating cover are fixedly set so that the conical cover can rotate together with the toothed rotating cover and thus completely throw the impurities to the ground.
