Description

Technical Field

[0001] This utility model belongs to the field of subway maintenance and operation technology, specifically involving a cleaning device for flexible contact network insulators in subway parking lots and depots. Background Technology

[0002] Contact line insulators play a crucial role in separating energized and non-energized conductors. However, due to the open-air environment, dust and other contaminants easily accumulate on the insulator surface, causing a decline in insulation performance. If cleaning is not timely or thorough, it can lead to safety hazards such as insulator flashover, directly threatening power supply safety. At the same time, keeping the insulator surface clean also helps extend its service life and reduce operation and maintenance costs.

[0003] According to research, the current industry practice for cleaning flexible contact network insulators involves maintenance personnel manually cleaning them with cloths. Due to the considerable height of the equipment, ladder trucks cannot reach them, requiring maintenance personnel to use the inspection vehicle's elevated platform to climb the ladder or other equipment for cleaning, posing certain safety hazards. Furthermore, to ensure the quality of insulator cleaning, cleaning cloths must be replaced promptly when soiled or washed with water on-site before reuse. This results in low utilization of the work plan, high operational costs, safety hazards, and a large consumption of cleaning consumables such as cloths.

[0004] Some convenient cleaning devices have been disclosed in the literature, such as Chinese patent CN220215896U. These devices use an adjustable assembly connecting an insulated handle and a cleaning component. The adjustable assembly can be adjusted to allow the cleaning component to tilt up and down and / or swing left and right relative to the insulated handle to different orientations. However, the dual-head brushes disclosed in these documents have cleaning blind spots, and the locking of the adjustment mechanism affects the applied force, resulting in insufficient cleaning power and affecting the cleaning effect. Furthermore, there is currently a lack of high-performance dedicated portable cleaning devices on the market. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of inefficiency and safety of manual cleaning and inconvenience of electric cleaning operation. It provides a flexible contact wire insulator cleaning device that allows cleaning personnel to complete the cleaning work within the ladder truck or on the ground without having to climb twice. It also eliminates the need for frequent replacement of cleaning consumables, eliminates safety hazards in maintenance operations, and significantly improves working time and efficiency.

[0006] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a flexible contact wire insulator cleaning device, including a battery, a telescopic rod, a motor, and a cleaning brush. A battery with a switch is installed at the hand-held end of the telescopic rod, and the battery is connected to the motor and supplies power to the motor. An angle adjustment mechanism is installed at the top of the telescopic rod, and the motor is installed at the top of the telescopic rod through the angle adjustment mechanism. The output shaft of the motor drives and connects to the clamp assembly, and the cleaning brush is installed in the clamp assembly. The angle adjustment mechanism consists of two rotating plates, one end of which is circular and has a screw hole in the center. The straight edges of the two rotating plates are fixedly connected to the top of the telescopic rod and the motor mounting bracket, respectively. The circular ends of the two rotating plates are movably installed relative to each other and locked by locking bolts connected to the screw holes.

[0007] Furthermore, the angle adjustment mechanism consists of two rotating plates, each with circumferentially arranged positioning teeth at its circular end, and the positioning teeth of the two rotating plates mesh with each other.

[0008] Furthermore, the battery is connected to the motor via wires, which are placed inside the telescopic rod.

[0009] Furthermore, the battery is a rechargeable battery, and it has a power display screen and a force adjustment switch.

[0010] Furthermore, the cleaning brush is a spherical brush.

[0011] Furthermore, the telescopic rod is a sleeve-type telescopic rod with a length of 1.8-2.4m, and the telescopic rod has telescopic buckles to achieve telescopic extension and fixation.

[0012] Compared with similar products, this utility model has a simple structure, is lightweight and easy to use, and is simple to operate. The cleaning brush is driven by a motor to ensure cleaning quality. The device can extend and retract freely within 1.8-2.4m, and the cleaning brush angle can be freely adjusted within 280 degrees through the angle adjustment teeth to meet the cleaning effect of insulators in different installation positions and meet various usage scenarios. Personnel can clean inside the ladder truck or on the ground. The cleaning brush is more resistant to dirt than a rag and does not need to be frequently replaced during operation. The cleaning operation of insulators inside and outside the field can be completed using only the ladder truck without the need for a grid maintenance vehicle, secondary climbing or climbing equipment.

[0013] Previously, cleaning flexible insulators in the depot required personnel to use engineering vehicles to raise the platform. For higher areas within the depot, ladders were needed for secondary access. Based on statistics from Shenyang's currently operating metro lines 1-10, there are over 8,000 flexible contact network insulators, requiring over 300 train maintenance schedules annually to complete the task, costing over 350,000 yuan in train fuel and 0.5 tons of cleaning supplies – a significant expense. Using the flexible cleaning device, only about 70 maintenance schedules are needed to complete the cleaning work. There's no need for a network inspection vehicle; ladder trucks or ground-based operations are sufficient. The cleaning brushes are cheaper and more durable than rags, eliminating the need for frequent replacements and saving substantial cleaning supplies while reducing environmental pollution.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to the specific embodiments. Example

[0019] like Figure 1 and 2 The flexible contact wire insulator cleaning device shown has a battery 1 installed at the hand-held end of the telescopic rod 3. The battery is a rechargeable lithium battery with a power display screen 11 and a power adjustment switch 2. The switch can adjust the intensity as needed. The battery is connected to the motor 7 through the wire 12 and supplies power to the motor. The top of the telescopic rod 3 has a connecting buckle 5. The telescopic rod is installed on the angle adjustment mechanism 6 through the connecting buckle. The motor 7 is fixed to the angle adjustment mechanism 6 through the motor fixing bracket 8. The motor output shaft drives the connecting clamp assembly 9, and the cleaning brush 10 is installed on the clamp assembly.

[0020] The angle adjustment mechanism 6, as described above Figure 3 As shown, it includes two rotating plates 13. One end of the rotating plate is circular and has a screw hole 14 in the center. The straight edges of the two rotating plates are fixedly connected to the top of the telescopic rod and the motor mounting bracket, respectively. The circular end has positioning teeth 15 arranged in a circle. The circular ends of the two rotating plates are movably installed and the positioning teeth mesh with each other, and are locked by locking bolts 16 connected to the screw hole.

[0021] Preferably, the wire 12 is placed inside the telescopic rod 3 for easier operation.

[0022] The cleaning brush 10 uses spherical bristles, making it easier to clean without dead angles.

[0023] Generally, the telescopic pole 3 is a sleeve-type telescopic pole with a length of 1.8-2.4m. The telescopic pole has a telescopic pole fixing buckle 4 to realize the telescopic pole extension and fixation.

[0024] Specific usage instructions:

[0025] When using the device, adjust the distance between the insulator to be cleaned and the maintenance personnel by rotating the telescopic rod fixing buckle. The telescopic rod will then be extended or shortened to the appropriate length. Tighten the telescopic rod fixing buckle to lock it in place. After adjusting the length of the telescopic rod, adjust the angle according to the required angle of the cleaning brush. To adjust the angle, first loosen the locking bolt of the angle adjustment mechanism to disengage the two rotating plates. Rotate the rotating plates to the desired angle, then press the two rotating plates together until the positioning teeth engage and the bolt is tightened to lock the angle. Then, press the battery switch to start the motor, which will drive the cleaning brush to rotate. Maintenance personnel can then hold the device and perform the cleaning work from inside the ladder truck platform. Testing has shown that the device can automatically clean insulators. After cleaning, surface dust and dirt are effectively removed without damaging the insulators. The strength of the telescopic rod and the operable height meet the requirements. Insulation resistance testing using an insulation resistance meter showed no impact on the performance of the insulators before and after cleaning.
