Description

Technical Field

[0001] This utility model belongs to the field of inspection robot technology, specifically an inspection robot used for unblocking the inside of pipelines. Background Technology

[0002] Pipeline internal cleaning and inspection robots are automated devices used to inspect and clean the inside of pipelines. They can use high-definition cameras to check the structural integrity of the pipeline interior. For example, in urban sewage pipes, they can check for cracks, corrosion, deformation, etc. in the pipe walls. These cameras usually have wide-angle and zoom functions, allowing for comprehensive and close-up observation of the details inside the pipeline. They can detect the presence of foreign objects, such as stones, tree roots, garbage, and other blockages. In oil pipelines, they can promptly detect the accumulation of substances that may affect the smooth flow of the pipeline, such as wax and rust. Through sensors (such as optical sensors and ultrasonic sensors), they determine the location and size of foreign objects, providing accurate information for subsequent cleaning work.

[0003] Chinese Patent Application No. 202322457380.9 discloses a municipal pipeline dredging robot, including a walking device, a mechanical gripper, and a universal joint. The walking device is connected to the mechanical gripper via the universal joint. The walking device includes a base and walking tracks. At least three walking tracks are evenly distributed around the circumference of the base, and each walking track is connected to the base via a linkage. A guide rod is provided on the side of the base away from the universal joint. One end of the guide rod is fixed to the base, and the other end of the guide rod is provided with a fixing plate. A positioning platform is slidably mounted on the guide rod, and a compression spring is sleeved on the guide rod between the positioning platform and the fixing plate. The robot is driven by three walking tracks, which can automatically adapt to the pipe diameter. Under the action of the compression spring and the linkage mechanism, the walking tracks always keep in contact with the inner wall of the pipe, which can effectively provide support, anti-slip function, and power.

[0004] However, the above-mentioned municipal pipeline dredging robot has the following problems in actual use: the contact between the three tracks and the inner wall of the pipeline mainly relies on the pressure given by the compression spring. However, after long-term use, the spring will become fatigued, which will reduce the pressure between the tracks and the inner wall of the pipeline, and thus reduce the friction between the tracks and the inner wall of the pipeline. Moreover, most pipeline inner walls are slippery, which can easily affect the robot's movement on the inner wall of the pipeline.

[0005] Therefore, an inspection robot for unblocking internal pipes is proposed to address the above problems. Utility Model Content

[0033] Specifically, the rinsing assembly 4 includes a water tank 401, which is connected to a water pump 402 via a pipe. The outlet of the water pump 402 is connected to a water guide pipe 403 via a pipe. The end of the water guide pipe 403 is connected to a nozzle 404. The nozzle 404 is installed on the outside of the robot body 1, and the position of the nozzle 404 corresponds to the track walking mechanism 3. When a large amount of adhering material is attached to the track of the track walking mechanism 3, high-pressure water can be used to rinse the outside of the track of the track walking mechanism 3 to avoid a large amount of adhering material interfering with the track walking mechanism 3.

[0034] Furthermore, the unblocking component 5 includes a second motor 501 installed inside the robot body 1. The output end of the second motor 501 is connected to a transmission rod 502.

In addition, this utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0040] Working principle and process: The inspection robot is placed inside the pipe. The first motor 201 of the adjustment component 2 is started, which in turn drives the gear ring 203 to rotate. The driven gear 204 then drives the rotating rod 205 to rotate. Under the action of the thread and the positioning rod 206, the moving blocks 207 move closer or further apart, causing the connecting rod 208 to tilt. The distance between the tracked walking mechanism 3 and the robot body 1 is changed according to the degree of tilt of the connecting rod 208, allowing the inspection robot to adapt to pipes of different diameters. The tracked walking mechanism 3 is then started, and the inspection robot... It can move inside the pipe. When a large amount of deposits adhere to the track of the track walking mechanism 3, the water pump 402 of the flushing component 4 is started. The water in the water tank 401 is sprayed out by the nozzle 404 after passing through the water pump 402 and the water guide pipe 403. High pressure water can be used to flush the outside of the track of the track walking mechanism 3 to avoid a large amount of deposits interfering with the track walking mechanism 3. When encountering blockages in the pipe, the second motor 501 of the unblocking component 5 is started. Then the transmission rod 502 drives the cutting blade 504 to rotate, which can cut up the blockage to facilitate unblocking the pipe.
