Description

Technical Field

[0001] This utility model relates to the technical field of inspection robots, specifically to a large-scale power distribution field inspection robot. Background Technology

[0002] With the continuous expansion of power systems, large-scale power distribution plants, as core nodes for power transmission and distribution, directly determine the reliability of power supply based on the stability of their equipment operation. Due to the dense density and wide coverage of equipment within power distribution plants, and the fact that some equipment is located in high-voltage and high-altitude environments, manual inspection is not only inefficient but also poses safety risks such as electric shock and falls from heights. Therefore, inspection robots have gradually become the mainstream equipment for inspecting large-scale power distribution plants. Existing inspection robots mostly adopt a track-based structure. During long-term use, the track surface is prone to rough wear due to dust accumulation and environmental corrosion, leading to a significant increase in the friction coefficient between the slider and the track. This can cause movement jams and accelerate track wear. To overcome high resistance, the robot's drive motor needs to continuously output higher power, resulting in excessively rapid energy consumption and a significant decrease in endurance. Utility Model Content

[0003] This utility model proposes a large-scale power distribution field inspection robot. During the movement of the inspection mechanism along the track, the pressurization component operates synchronously, and the pressure in the oil tank gradually increases, providing stable oil pressure for the coating component. The lubricating oil in the oil tank is diverted to the sponge rings on both sides, and the sponge rings evenly coat the lubricating oil on the track contact surface to achieve a lubrication effect.

[0004] Therefore, the technical solution adopted is as follows:

[0005] A large-scale power distribution plant inspection robot includes a track and an inspection mechanism. The inspection mechanism includes a sliding block that matches the track, a driving component that drives the sliding block to move along the track, and a coating component. An oil tank is fixed on the sliding block. The coating component includes two connecting ring tubes located at both ends of the sliding block and sleeved on the track. Both connecting ring tubes are connected to the oil tank. A sponge ring is fixed inside the connecting ring tube, and multiple through holes are opened on the inner side wall. A pressurization component is connected to the oil tank.

[0006] A further technical solution is that an electric push rod is connected to the bottom of the sliding block, and a mounting block is fixed to the movable end of the electric push rod. A sensor and a camera are fixed on the mounting block.

[0007] A further technical solution is that the sliding block is provided with a through groove, and multiple balls are rotatably connected to the inside of the through groove. The multiple balls abut against the side wall of the track, and two connecting ring tubes are located at both ends of the through groove and fixed to the sliding block.

[0008] A further technical solution is that the drive assembly includes a motor and a gear, a rack is fixed on the track, the gear is rotatably connected to the top of the sliding block, the gear meshes with the rack, and the motor is fixed to one side of the oil tank and drives the gear to rotate.

[0009] A further technical solution is that the drive assembly also includes a belt, a rotating shaft is fixed to the output end of the motor, a driving pulley is fixed to the rotating shaft, a driven pulley is fixed to the gear, and the driving pulley is connected to the driven pulley via a belt.

[0010] A further technical solution is that the coating assembly includes an oil injection main pipe, which is fixed to one side of the oil storage tank and connected to the oil storage tank. Both connecting ring pipes are connected to the oil injection main pipe through an oil injection branch pipe.

[0011] A further technical solution is that the pressurizing assembly includes a pressurizing box, a slide rod is slidably connected inside the pressurizing box, a piston block is fixed at one end of the slide rod inside the pressurizing box, and a bracket is fixed at the other end of the slide rod extending out of the pressurizing box. A roller is rotatably connected to the bracket, a spring is sleeved on the slide rod, a cam is sleeved and fixed on the rotating shaft, the cam abuts against the roller, an air inlet pipe and an air outlet pipe are respectively connected to the side wall of the pressurizing box, the air outlet pipe is connected to the oil storage tank, and a one-way valve is connected inside both the air inlet pipe and the air outlet pipe.

[0012] The working principle and beneficial effects of this application are as follows:

[0013] As the inspection mechanism moves along the track, the pressurization components operate synchronously, and the pressure in the oil tank gradually increases, providing stable oil pressure for the coating components. The lubricating oil in the oil tank is diverted to the connecting ring pipes on both sides. The lubricating oil permeates into the sponge ring through the through holes on the inner side of the connecting ring pipe. Since the sponge ring is in contact with the track surface, when the inspection mechanism moves, the sponge ring evenly coats the lubricating oil on the track contact surface, achieving a lubrication effect, reducing movement resistance, reducing sliding jamming, avoiding accelerated component wear due to excessive friction, and reducing power consumption, thereby improving the equipment's endurance.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figures 1-5 As shown, a large-scale power distribution plant inspection robot includes a track 1 and an inspection mechanism 2. The inspection mechanism 2 includes a sliding block 21 matched with the track 1, a driving component 23 for driving the sliding block 21 to move along the track 1, and a coating component 25. An oil storage tank 22 is fixed on the sliding block 21. The coating component 25 includes two connecting ring tubes 251 located at both ends of the sliding block 21 and sleeved on the track 1. Both connecting ring tubes 251 are connected to the oil storage tank 22. A sponge ring 252 is fixed inside the connecting ring tube 251, and multiple through holes are opened on the inner side wall. A pressurization component 24 is connected to the oil storage tank 22.

[0023] In this embodiment, the bottom of the sliding block 21 is connected to an electric push rod 26, and the movable end of the electric push rod 26 is fixed with a mounting block 27. A sensor 29 and a camera 28 are fixed on the mounting block 27. In this embodiment, the inspection mechanism 2 is controlled to move along the track 1 by the drive component 23 to start the inspection work. According to the height requirements of the power distribution equipment, the staff remotely controls the extension and retraction of the electric push rod 26 to adjust the height of the mounting block 27. The mounting block 27 drives the camera 28 and the sensor 29 to move to a suitable position. The camera 28 takes real-time pictures of the appearance of the equipment and records whether there are any abnormalities such as loose parts, damage, oil leakage, or foreign objects. The sensor 29 detects parameters such as equipment temperature, insulation resistance, and ambient humidity. If an abnormality is detected, an early warning signal is sent to the background in real time.

[0024] As the inspection mechanism 2 moves along the track 1, the pressurizing component 24 operates synchronously, and the pressure in the oil tank 22 gradually increases, providing stable oil pressure for the coating component 25. The lubricating oil in the oil tank 22 is diverted to the connecting ring pipes 251 on both sides. The lubricating oil permeates into the sponge ring 252 through the through hole on the inner side of the connecting ring pipe 251. Since the sponge ring 252 is in contact with the surface of the track 1, when the inspection mechanism 2 moves, the sponge ring 252 evenly coats the lubricating oil on the contact surface of the track 1, achieving a lubrication effect, reducing movement resistance, reducing sliding jamming, avoiding accelerated component wear due to excessive friction, and reducing power consumption, thereby improving the equipment's endurance.

[0025] like Figure 2 As shown, a through groove is provided on the sliding block 21, and multiple ball bearings are rotatably connected to the inner side of the through groove. All the ball bearings abut against the side wall of the track 1. Two connecting ring tubes 251 are located at both ends of the through groove and fixed to the sliding block 21. The ball bearings are used to reduce the coefficient of friction between the sliding block 21 and the track 1, making the sliding block 21 move more smoothly.

[0026] like Figure 3 As shown, the drive assembly 23 includes a motor 231 and a gear 236. A rack 3 is fixed on the track 1. The gear 236 is rotatably connected to the top of the sliding block 21 and meshes with the rack 3. The motor 231 is fixed to one side of the oil reservoir 22 and drives the gear 236 to rotate. A rotating shaft 232 is fixed to the output end of the motor 231. A drive pulley 234 is fixed on the rotating shaft 232, and a driven pulley 235 is fixed on the gear 236. The drive pulley 234 is connected to the driven pulley 235 via a belt 237.

[0027] In this embodiment, the motor 231 is started, and the output end of the motor 231 drives the rotating shaft 232 to rotate. The rotating shaft 232 synchronously drives the driving pulley 234 to rotate. The driving pulley drives the driven pulley 235 to rotate through the belt 237. The driven pulley 235 is fixedly connected to the gear 236, driving the gear 236 to rotate synchronously. The gear 236 meshes with the rack 3 on one side of the track 1, and the rotational motion is converted into horizontal linear motion, pushing the sliding block 21 to move along the track 1. The sliding block 21 drives the oil tank 22 and the coating component 25 to move synchronously, and the inspection work begins.

[0028] like Figure 5 As shown, the coating assembly 25 includes an oil injection main pipe 253, which is fixed to one side of the oil reservoir 22 and connected to it. A pair of connecting ring pipes 251 each have an oil injection branch pipe 254 installed on their side walls, and both branch pipes 254 are connected to the oil injection main pipe 253. Lubricating oil in the oil reservoir 22 enters the branch pipes 254 through the oil injection main pipe 253 and is distributed to the connecting ring pipes 251 on both sides, thereby uniformly coating the lubricating oil onto the contact surface of the track 1 to achieve a lubrication effect.

[0029] like Figure 4 As shown, the pressurization assembly 24 includes a pressurization box 241. A slide rod 246 is slidably connected inside the pressurization box 241. A piston block 248 is fixed at one end of the slide rod 246 inside the pressurization box 241, and a bracket 244 is fixed at the other end of the slide rod 246. A roller 245 is rotatably connected to the bracket 244. A spring 247 is sleeved on the slide rod 246. A cam 233 is sleeved and fixed on the rotating shaft 232. The cam 233 abuts against the roller 245. An air inlet pipe 242 and an air outlet pipe 243 are respectively connected to the side wall of the pressurization box 241. The air outlet pipe 243 is connected to the oil storage tank 22. A one-way valve is connected inside both the air inlet pipe 242 and the air outlet pipe 243.

[0030] In this embodiment, when the rotating shaft 232 rotates, the cam 233 on the outer wall rotates synchronously. The cam 233 and the roller 245 convert the rotational motion of the motor 231 into linear reciprocating motion. The slide rod 246 and the piston block 248 form a piston structure for compressing air. The spring 247 provides the return force of the piston to ensure continuous operation. The one-way valves in the inlet pipe 242 and the outlet pipe 243 ensure unidirectional gas flow. The one-way valve in the inlet pipe 242 only allows outside air to enter the pressurization box 241, and the one-way valve in the outlet pipe 243 only allows the compressed air in the pressurization box 241 to enter the oil storage tank 22 to prevent gas backflow and ensure pressurization effect.

[0031] Specifically, when the motor shaft 232 rotates, the cam 233 fixed on it rotates accordingly. The cam 233 periodically squeezes the roller 245, pushing the bracket 244 and the slide bar 246 to move into the pressure box 241, compressing the spring 247 and pushing the piston block 248 to move. The reciprocating motion of the piston block 248 creates the effect of a pneumatic pump in the pressure box 241, increasing the air pressure in the oil reservoir 22 and generating pressure on the internal lubricating oil, thereby delivering the lubricating oil to the coating assembly 25.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
