Robot for flaw detection of tap water pipeline

Abstract

The invention discloses a robot for flaw detection of a tap water pipeline, and relates to the technical field of pipeline flaw detection, the robot comprises a shell, the upper surface of the shell is fixedly connected with an ultrasonic flaw detection device, the back of the shell is provided with a rotary spraying device, and the rear end of the inner surface of the shell is provided with a stirring device; the lower end of the inner surface of the shell is rotationally connected with a first rotating shaft. The robot for flaw detection of the tap water pipeline is provided with the moving wheels, when the robot is placed in the pipeline, the moving wheels on the two sides can make contact with the inner wall of the pipeline, certain pressure can be provided for the interior of the pipeline under the action of the limiting springs, and then the transverse center lines of the moving wheels coincide with the center line of the cross section of the pipeline; therefore, the ultrasonic flaw detection device is always located in the center of the pipeline, flaw detection can be accurately carried out on the inner wall of the pipeline, ultrasonic detection nonuniformity caused when the device is located on the bottom face or the upper end of the pipeline is prevented, and the measurement accuracy of the device is better.

Description

technical field [0001] The invention relates to the technical field of pipeline flaw detection, in particular to a robot for flaw detection of tap water pipelines. Background technique [0002] Water pipes are water supply pipes. Modern decoration water pipes are constructed with buried walls. There are three types of water pipes. The first type is metal pipes, such as hot-dip cast iron pipes with plastic lining, copper pipes, and stainless steel pipes. The second type is metal pipes. Plastic-composite metal pipes, such as steel-plastic composite pipes, aluminum-plastic composite pipes, etc. The third type is plastic pipes, such as PB pipes, PPR pipes, etc. The more common water pipes on the market include PPR water pipes and aluminum-plastic pipes. Copper pipes, etc., PPR water pipes are a new type of water pipe material, which can be used as cold and hot water pipes, and PPR water pipes have no toxicity, are extremely light in weight, and can be widely used when used.

Problems solved by technology

[0003] Existing water pipes are generally in the form of hidden pipes, that is, fixed inside the wall. In many families, the old pipe network leaks seriously, and the pipes often burst. From the perspective of water quality, secondary pollution is prone to occur. Therefore, it is necessary to replace or Repairing pipes often requires damage to the wall, and it is not easy to find water seepage points in pipes with slight water seepage
