Intelligent cleaning device

Abstract

This utility model discloses an intelligent cleaning device, including a boom lift truck. The boom lift has a connecting frame rotatably connected to its front end via a hydraulic motor. Support arms are fixedly installed on both outer walls of the connecting frame. Anti-collision mechanisms are installed at the bottom, top, and support arms of the connecting frame. Multiple drive boxes are fixedly installed on the outer wall of the connecting frame. In use, the boom lift truck is moved and the connecting frame is raised to the desired height. High-pressure nozzles are then used to perform high-pressure rinsing on the post insulators, effectively removing dirt from their surface. The hydraulic motor drives the high-pressure nozzles to swing left and right. Activating the reduction servo motor drives the corresponding swing arm to move the high-pressure nozzles up and down, facilitating multi-angle rinsing of the grooves on the post insulator surface to ensure cleaning effectiveness. Compared to manual cleaning, this device significantly improves cleaning efficiency.

Description

Technical Field

[0001] This utility model relates to the field of power maintenance technology, specifically an intelligent cleaning device. Background Technology

[0002] The DC field is a core component of the high-voltage direct current (HVDC) transmission system. It is mainly located in the converter station of the HVDC transmission system. After the AC and DC power are converted to each other, the HVDC power is collected, distributed, filtered, measured and protected, and then the power is efficiently transmitted through the DC transmission lines.

[0003] There are usually hundreds of post insulators in a DC field, and the average height of the post insulators is 13.5m. During maintenance and cleaning, traditional manual cleaning is carried out by two teams of 4 people each with a 20-meter aerial work platform. The operation is time-consuming and labor-intensive, and the cleaning time for a single post insulator usually takes 2-4 hours, which is inefficient. Therefore, we propose an intelligent cleaning device. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 In this embodiment of the present invention, an intelligent cleaning device includes a boom lift 1, specifically a 20m boom-type aerial work platform with a maximum working height of 20.16m, capable of meeting the cleaning needs of support insulators. The boom lift 1 is controlled by a backpack remote control. The front end of the boom of the boom lift 1 is rotatably connected to a connecting frame 6 via a hydraulic motor 4. Support arms 8 are fixedly installed on both outer walls of the connecting frame 6. Anti-collision mechanisms 9 are installed at the bottom, top, and support arms 8 of the connecting frame 6. Multiple drive boxes 13 are fixedly installed on the outer walls of the connecting frame 6. A swing arm 14 is rotatably mounted on each of the articulated boom lift 14. A high-pressure nozzle 15 is fixedly mounted on the outer wall of the articulated boom lift 14. The high-pressure nozzle 15 is connected to the high-pressure water pump 3 through a pressure-bearing hose. Each pressure-bearing hose is equipped with a solenoid valve. A geared servo motor 18 for driving the swing arm 14 is installed in the drive box 13. A water tank 2 and a high-pressure water pump 3 are fixedly mounted on the chassis of the articulated boom lift 1. The high-pressure water pump 3 is powered by the articulated boom lift 1. A control box 5 is fixedly mounted on the articulated boom lift 1. The high-pressure water pump 3, the geared servo motor 18, and the solenoid valves are all connected to the main controller in the control box 5. The main controller is wirelessly connected to a backpack remote control.

[0020] By adopting the above-mentioned solution, this utility model allows for the following operation: The boom lift 1 is moved using a backpack remote control, and the connecting frame 6 is raised to the desired height. Then, the high-pressure water pump 3 and solenoid valve are activated, enabling high-pressure rinsing of the support insulators using high-pressure nozzles 15. This effectively removes dirt adhering to the surface of the support insulators. The hydraulic motor 4 drives each high-pressure nozzle 15 to swing left and right. Activating the reduction servo motor 18 drives the corresponding swing arm 14 to swing the high-pressure nozzles 15 up and down, facilitating multi-angle rinsing of the grooves on the surface of the support insulators to ensure cleaning effectiveness. Compared to manual cleaning, this significantly improves cleaning efficiency.

[0021] Specific combination Figure 2 In one embodiment of this utility model, the hydraulic motor 4 is fixedly connected to the front end of the boom of the boom lift 1, and the connecting arm 7 is fixedly installed on the outer wall of the connecting frame 6. The connecting arm 7 is fixedly connected to the output shaft of the hydraulic motor 4.

The swing arm 14 is fixedly sleeved on the end of the rotating shaft 17. The output shaft of the deceleration servo motor 18 is fixedly connected to a first gear 19. A second gear 20 is fixedly sleeved on the outer wall of the rotating shaft 17 inside the drive box 13. The first gear 19 and the second gear 20 mesh with each other.

[0023] By starting the geared servo motor 18 to drive the first gear 19 to rotate, the first gear 19 and the second gear 20 can be used to drive the rotating shaft 17 to rotate, thereby causing the swing arms 14 and the high-pressure nozzle 15 at both ends of the rotating shaft 17 to swing.

[0024] Specific combination Figure 2 and Figure 4 In one embodiment of this utility model, gas springs 16 are provided on both sides of the drive box 13. One end of the gas spring 16 is rotatably connected to the drive box 13, and the other end of the gas spring 16 is rotatably connected to the corresponding swing arm 14. By setting the gas spring 16, the swing arm 14 can be tensioned to improve the stability of the swing arm 14 when the high-pressure nozzle 15 is working.

[0025] Specific combination Figure 2 and Figure 3 In one embodiment of this utility model, the anti-accidental contact mechanism 9 includes a protective shell 10 fixedly installed on the connecting frame 6 and the support arm 8.
