Robot for detecting blockage condition of drainage pipeline and detection method

Abstract

The invention discloses a robot used for detecting the blocking condition of a drainage pipeline, the robot comprises a vehicle body and a walking mechanism, a camera shooting assembly is arranged on the vehicle body, the camera shooting assembly comprises a camera and a first lifting mechanism, the first lifting mechanism is arranged on the vehicle body, the camera is connected to the first lifting mechanism, and the walking mechanism is arranged on the vehicle body. The vehicle body is further provided with a sonar and a ground penetrating radar, the ground penetrating radar is arranged below the vehicle body, impurities such as concrete crystals above the water surface, in the water and below the water in the drainage pipeline can be detected at the same time, the whole blockage condition of a certain position is obtained at the same time, an image can be drawn in combination with control software, and the detection accuracy is improved. When a drainage pipeline in a similar environment needs to be cleaned, the image content can be directly used for targeted cleaning.

Description

technical field [0001] The invention belongs to the technical field of detection of drainage pipes, and more particularly relates to a robot and a method for detecting the blockage of drainage pipes. Background technique [0002] Drainage pipe refers to the pipe that is embedded in concrete to guide and drain water. The material is mostly PVC corrugated pipe. At present, the drainage pipes are blocked to varying degrees. There are various clogging factors, such as accumulation and sedimentation clogging caused by natural mud and sand not being drained in time, clogging caused by crystals formed by chemical reaction between groundwater and air and adhering to the inner wall of the pipeline, and caused by the inflow of concrete crystals and other debris during pipeline installation. of blockage. [0003] Before clearing the blockage in the drainage pipe, it is necessary to check the blockage inside the drainage pipe. At present, the usual practice is to use a robot to carry ...

Problems solved by technology

[0003] Before cleaning the blockage in the drainage pipe, it is necessary to check the blockage inside the drainage pipe. At present, the usual practice is to use a robot to carry a camera to take pictures and check the situation, but the camera can usually only view the area above the water surface. However, the water in the drainage pipe is usually dirty and cannot be seen clearly. At the same time, it is impossible to detect the concrete crystallization and other sundries at the bottom of the drainage pipe, so it is difficult to make a targeted cleaning plan.
