Description

Technical Field

[0001] This utility model relates to the field of high-voltage contact cleaning technology, and in particular to a multi-nozzle cleaning device for high-voltage contacts. Background Technology

[0002] With economic and social development, people's requirements for power supply are constantly increasing, and the demand for live-line work is also increasing. Various insulated aerial work platforms have emerged and have been widely used. High-voltage contacts, also known as plum blossom contacts, are widely used in power equipment such as GIS switches and vacuum switches. Most of the conductive primary components used in these devices use high-voltage contacts as the main conductive connectors. When cleaning high-voltage contacts, a multi-nozzle cleaning device for high-voltage contacts is generally used.

[0003] Existing technologies, such as patent CN207723112U, disclose a multi-nozzle cleaning device for high-voltage contacts. This patent employs a first support plate; a vehicle battery mounted on the first support plate; a six-axis robot arm mounted on the vehicle battery; a second support plate, on which a dry ice emitter is mounted, and the second support plate is rotatably mounted on one side of the first support plate to keep the dry ice emitter vertically positioned; and a probe carrier plate mounted on the end of the six-axis robot arm away from the first support plate. The probe carrier plate is retractably equipped with at least one dry ice spray head, at least one rust remover spray head, at least one lubricating oil spray pipe, and at least one Vaseline brush head, wherein at least one dry ice spray head is connected to the dry ice emitter. Through the above method, this utility model solves the problems of existing equipment, which mainly relies on manual handling for cleaning. However, due to the high voltage of the high-voltage contacts, there is a risk of electric shock, which is unsafe, and the cleaning effect is poor because it involves manual cleaning of the high-voltage contacts.

[0004] In daily operation, the equipment has the following problems: the existing equipment is generally a one-piece unit, which makes it difficult to clean the items from different angles, resulting in the equipment being unable to clean the items thoroughly. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where equipment cannot thoroughly clean the objects to be cleaned, and to propose a multi-nozzle cleaning device for high-pressure contacts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-nozzle cleaning device for high-voltage contacts, comprising a placement plate, a handrail, a mounting arm, rollers, and a spray pipe. The handrail is fixedly connected to the upper end of the placement plate, the mounting arm is fixedly connected to the upper end of the placement plate, the rollers are located at the lower end of the placement plate, and the spray pipe is rotatably connected to the upper end of the mounting arm. One end of the spray pipe is provided with an adjustment device, which includes a limiting wheel and a positioning plate. The positioning plate is fixedly connected to the side of the mounting arm, the limiting wheel is fixedly connected to one end of the spray pipe, a moving rod is slidably connected inside the positioning plate, the moving rod is rotatably connected inside the limiting wheel, a rotating arm is rotatably connected to the lower end of the moving rod, and a turntable is rotatably connected to the lower end of the rotating arm.

[0007] Furthermore, a connecting rod is fixedly connected to the side of the turntable, and a motor is fixedly connected to the end of the connecting rod away from the turntable. By setting the turntable and the connecting rod, the rotating arm can be reciprocated, reducing the difficulty of the rotating arm moving up and down during use.

[0008] Furthermore, a connecting seat is fixedly connected to the surface of the motor. The connecting seat is located on the side of the mounting arm and is fixedly connected to facilitate the limiting of the motor.

[0009] Furthermore, a fixing plate is rotatably connected to the surface of the connecting rod. The fixing plate is fixedly connected to the side of the mounting arm. The fixing plate facilitates the limiting of the connecting rod.

[0010] Furthermore, a protective device is provided at the upper end of the placement plate. The protective device includes a connecting frame and a slide rail. The connecting frame is fixedly connected to the upper end of the placement plate, and the slide rail is fixedly connected to the upper end of the connecting frame. A limit groove is formed on the side of the slide rail, and a connecting arm is rotatably connected inside the slide rail. A protective cover is fixedly connected to the end of the connecting arm away from the slide rail, and a rubber plate is fixedly connected to the surface of the protective cover. A pull groove is formed on the side of the connecting arm, and a pull rod is slidably connected inside the pull groove. By setting up the protective cover, the surface of the nozzle can be protected, reducing the likelihood of dust adhering to the surface of the nozzle and causing nozzle blockage when the equipment is placed.

[0011] Furthermore, a spring is fixedly connected to one end of the pull rod, and the end of the spring away from the pull rod is fixedly connected to the inside of the pull groove. The spring is provided to facilitate the application of a restoring force to the pull rod.

[0012] Furthermore, a limiting rod is fixedly connected to the surface of the pull rod, and the limiting rod is engaged with the inside of the limiting groove. The limiting rod is provided to facilitate the limiting of the connecting arm.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an adjustment device, when the user starts the motor, the motor rotates and drives the connecting rod to rotate. When the connecting rod rotates, it drives the turntable to rotate. The rotation of the turntable drives the rotating arm to move. The movement of the rotating arm drives the moving rod to move back and forth inside the positioning plate. Then, the moving rod drives the limit wheel to move up and down, rotating the nozzle on the surface of the mounting arm. By setting an adjustment device, the nozzle can be effectively adjusted, thus adjusting the nozzle angle. Existing equipment is generally a one-piece unit, which makes it difficult to clean the object at different angles, resulting in the inability to clean the object thoroughly. This adjustment device, through the coordinated cooperation of the motor, connecting rod, turntable, moving rod and other components, realizes the multi-angle and flexible position adjustment of the nozzle. Compared with traditional equipment, it greatly improves the flexibility and accuracy of cleaning, ensuring that every part of the high-pressure contact is thoroughly cleaned, and effectively improving the cleaning effect.

[0015] 2. In this utility model, by setting a protective device, when the equipment is in use, the user pulls the lever, causing the spring to deform and generate elastic force. When the lever moves, it causes the limiting rod to move and disengage from the inside of the limiting groove. Then the connecting arm is unrestrained, and the rotating connecting arm causes the protective cover to be fitted onto the surface of the nozzle. By setting a protective device, the surface of the nozzle is effectively protected, which reduces the situation where dust easily adheres to the nozzle surface when the equipment is placed, causing the nozzle to become clogged and unable to operate normally. This protective device, through the setting of components such as the connecting arm, protective cover, and rubber plate, protects the surface of the nozzle and greatly improves the service life of the nozzle.

A rotating arm 64 is rotatably connected to the lower end of the moving rod 62. A turntable 65 is rotatably connected to the lower end of the rotating arm 64.

[0026] Specifically, a connecting rod 66 is fixedly connected to the side of the turntable 65, and a motor 67 is fixedly connected to the end of the connecting rod 66 away from the turntable 65.

[0027] In this embodiment, by setting up a turntable 65 and a connecting rod 66, the rotating arm 64 can be reciprocated, reducing the difficulty of the rotating arm 64 moving up and down during use.

[0028] Specifically, a connecting seat 69 is fixedly connected to the surface of the motor 67. The connecting seat 69 is fixedly connected to the side of the mounting arm 3. The connecting seat 69 is provided to facilitate the limiting of the motor 67.

[0029] Specifically, a fixing plate 68 is rotatably connected to the surface of the connecting rod 66. The fixing plate 68 is fixedly connected to the side of the mounting arm 3. The fixing plate 68 is provided to facilitate the limiting of the connecting rod 66.

[0030] In this embodiment: a protective device 7 is provided at the upper end of the placement plate 1. The protective device 7 includes a connecting frame 71 and a slide rail 72. The connecting frame 71 is fixedly connected to the upper end of the placement plate 1, and the slide rail 72 is fixedly connected to the upper end of the connecting frame 71. A limit groove 73 is opened on the side of the slide rail 72. A connecting arm 74 is rotatably connected inside the slide rail 72. A protective cover 75 is fixedly connected to the end of the connecting arm 74 away from the slide rail 72. A rubber plate 76 is fixedly connected to the surface of the protective cover 75. A pull groove 77 is opened on the side of the connecting arm 74. A pull rod 78 is slidably connected inside the pull groove 77.

[0031] In this embodiment: by setting a protective cover 75, the surface of the nozzle 5 can be protected, reducing the likelihood of dust adhering to the surface of the nozzle 5 when the equipment is placed, thus preventing the nozzle 5 from becoming clogged.

[0032] Specifically, a spring 79 is fixedly connected to one end of the pull rod 78, and the end of the spring 79 away from the pull rod 78 is fixedly connected to the inside of the pull groove 77. The spring 79 is provided to facilitate the application of a restoring force to the pull rod 78.

[0034] Working Principle: When the equipment is in use, the user starts the motor 67. The rotation of the motor 67 drives the connecting rod 66 to rotate, which in turn drives the turntable 65 to rotate. The rotation of the turntable 65 moves the rotating arm 64, which in turn moves the moving rod 62 back and forth inside the positioning plate 63. The moving rod 62 then drives the limit wheel 61 to move up and down, rotating the nozzle 5 on the surface of the mounting arm 3. By setting the adjustment device 6, the nozzle 5 can be effectively adjusted, thus adjusting its angle. Existing equipment is generally a single unit, making it difficult to clean the object at different angles, resulting in incomplete cleaning. This adjustment device 6, through the coordinated operation of the motor 67, connecting rod 66, turntable 65, and moving rod 62, enables multi-angle and flexible position adjustment of the nozzle 5. Compared to traditional equipment, this greatly improves the flexibility and precision of cleaning, ensuring that every part of the high-pressure contact is thoroughly cleaned, effectively enhancing the cleaning effect.

[0035] When the equipment is in use, the user pulls the lever 78, causing the spring 79 to deform and generate elastic force. When the lever 78 moves, it causes the limiting rod 710 to move and disengage from the limiting groove 73. Then the connecting arm 74 is unrestrained. Rotating the connecting arm 74 causes the protective cover 75 to be fitted onto the surface of the nozzle 5. By setting the protective device 7, the surface of the nozzle 5 is effectively protected, which reduces the likelihood of dust accumulating on the surface of the nozzle 5 when the equipment is placed, causing the nozzle 5 to become clogged and unable to operate normally. This protective device 7, through the setting of components such as the connecting arm 74, the protective cover 75, and the rubber plate 76, protects the surface of the nozzle 5 and greatly improves the service life of the nozzle 5.
