Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a pipeline quality detection device for water conservancy projects. Background Art

[0002] In the construction of water conservancy projects, pipeline structure is an indispensable structure, which is widely used in various fields such as water supply and drainage. As the operation time of pipelines increases, water pipes will inevitably be damaged during long-term use, and the problem of pipeline aging is becoming increasingly prominent. Therefore, pipeline production, maintenance and other links all require pipeline quality inspection and evaluation.

[0003] At present, the commonly used inspection methods are manual inspection and robot inspection. Manual inspection not only requires the operator to conduct preliminary inspection of the inner surface of the pipeline through visual observation to determine whether the inner surface has problems such as aging, corrosion and wear, but also use a flaw detector to perform flaw detection on the wall of the pipeline to determine whether there are internal injuries such as holes and cracks in the pipeline wall. Obviously, the workload, work intensity and work difficulty of this inspection method are large, and manual inspection is impossible for pipelines with smaller diameters. At this time, a robot is needed to enter the pipeline for inspection. However, the function of the robot is relatively single, especially since the diameter specifications of the pipeline are diverse. The robot is not easy to adjust and adapt according to the diameter of the pipeline, resulting in its general adaptability and poor detection reliability. Therefore, there is still room for improvement in the quality inspection of pipelines.

[0004] Therefore, a pipeline quality detection device for water conservancy projects is needed to improve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a pipeline quality detection device for water conservancy projects to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A pipeline quality detection device for water conservancy projects includes a device body, a detection mechanism, a power connection mechanism, a hydraulic pump, a wireless controller, a moving mechanism, and a battery. A motor is fixedly installed inside the device body, and a rotating shaft is provided at the output end of the motor. The detection mechanism is installed at one end of the rotating shaft. The rotating shaft is located on the inner surface of the device body and the power connection mechanism is installed. The detection mechanism includes:

[0008] A housing, wherein a second motor is fixedly mounted inside the housing, and a rotating plate is provided for transmission at an output end of the second motor;

[0009] A rotating plate, on the surface of which several hinge rods are hingedly connected, and the other ends of the hinge rods are hingedly connected with arc-shaped plates;

[0010] An arc-shaped plate, which is rotatably arranged on the surface of the outer shell, and an ultrasonic flaw detector head is fixedly arranged at one end of the arc-shaped plate.

[0011] As a preferred solution of the present utility model, there are two power connection mechanisms, and each power connection mechanism includes an insulating mounting plate, a power connection slider and an annular power connection track.

[0013] As a preferred solution of the present utility model, a camera is arranged on one side of the outer shell.

[0014] As a preferred solution of the present utility model, the moving mechanism includes a hydraulic cylinder and a driving wheel. The hydraulic cylinder is driven by a hydraulic pump, and the driving wheel is fixedly arranged at one end of the hydraulic cylinder.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. In the present utility model, the hydraulic pump drives the hydraulic cylinder to inspect, so that the driving wheel contacts the inner wall of the pipeline, which is convenient for movement and adapts to pipelines of various sizes; <s

[0017] 2. In the present utility model, by starting the second motor to drive the rotating plate to rotate, the arc-shaped plate is pushed to open through the hinge rod, so that the ultrasonic flaw detector head is close to the inner wall for flaw detection work. At the same time, the first motor can be driven to rotate the rotating shaft, so as to drive the detection mechanism to rotate and adjust the position of the ultrasonic flaw detector head. At this time, the power connection slider of the power connection mechanism keeps sliding and contacting on the surface of the annular power connection track, and rotation will not affect power supply.
