AI Technical Summary
The existing water supply pipeline leakage detector requires the equipment to be held in hand during detection, which is poor in effect and inefficient, making it difficult to achieve all-round and efficient water leakage detection of the pipeline.
A water supply network leakage detector including fixed half-ring and rotating half-ring is designed. The roller and gear system is driven by the motor, so that the probe head can perform 360-degree blind angle measurements around the pipeline, combining the rolling of the ball and the half-ring ring. Connect to achieve automatic movement and rotation, ensuring comprehensive detection of the outer wall of the pipe by the probe head.
It improves the accuracy and efficiency of detection, so that the leakage detector can move and rotate on the outer wall of the pipeline by itself, achieving all-round blind spot measurements of the leakage points of the pipeline, significantly improving the detection effect.

Description
Technical Field
[0001] The utility model relates to the technical field of leak detectors, and in particular to a water supply network leak detector. Background Art
[0002] The pipeline system that delivers and distributes water to users in a water supply project is also called a water supply network. It includes water delivery channels, water distribution networks, booster pump stations, water towers, pools, and network ancillary facilities. Pipeline network leakage refers to the phenomenon of water leakage during the transportation process. There are many reasons for pipeline network leakage, such as damage to the main body of the pipeline, damage to the pipeline connection, and leakage of pipeline accessories (gates, valves, fire hydrants, etc.). In order to reduce the leakage rate, water companies in various places usually use pipeline network leak detectors to align and detect.
[0003] In the prior art, when using common pipeline leak detectors, the user needs to hold the detector in his hand and move the exposed pipeline to detect the leak. The detection effect is poor and the efficiency is also low. How to invent a water supply network leak detector to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content
[0004] In order to remedy the above deficiencies, the utility model provides a water supply network leak detector, which aims to improve the problem that the common pipeline leak detector has poor hand-held detection effect and lower efficiency during detection.
[0005] The utility model is achieved in this way:
[0006] The utility model provides a water supply network leak detector, comprising a first fixed half ring and a second fixed half ring and a rotating half ring installed on the inner wall thereof, wherein the inner wall of the first fixed half ring is provided with a first notch, the first fixed half ring is fixedly connected with a first connecting plate on both sides close to the first notch, the two ends of the first fixed half ring are fixedly connected with a fixing plate, and the upper end of the fixing plate is fixedly connected with a stud;

[0008] The two rotating half rings are respectively installed on the inner walls of the first notch and the second notch, wherein a detection head is installed on the inner wall of one of the rotating half rings, and one end of the rotating half ring is fixedly connected to a half ring gear ring.
[0009] Preferably, the inner walls of one end of the first fixed half ring and the second fixed half ring are both rollingly connected with a plurality of balls.
[0010] Preferably, a symmetrical mounting seat is fixedly connected to an inner wall of one side of the second fixed half ring, and a motor is mounted on one side of one of the mounting seats.
[0011] Preferably, the inner wall of the mounting seat is rotatably connected to a main shaft, one end of the main shaft is fixedly connected to the output end of the motor, the outer walls at both ends of the main shaft are fixedly connected to rollers rotatably connected to the pipeline, and the outer wall of one side of the main shaft is fixedly connected to a driving bevel gear.
[0012] By adopting the above technical solution, the first fixed half ring and the second fixed half ring are plugged and fixed as a whole through the studs and nuts, and then the motor is started to rotate the roller to drive the entire device to move along the pipeline, and the side leakage of the pipeline is detected through the detection head on one side.
[0013] Preferably, an ear plate is fixedly connected to the inner wall of one side of the second fixed half ring, the inner wall of the ear plate is rotatably connected to a secondary shaft, and one end of the secondary shaft is fixedly connected to a gear meshing with the half ring gear.
[0014] Preferably, one end of the secondary shaft is fixedly connected with a driven bevel gear meshing with the driving bevel gear.
[0015] By adopting the above technical solution, while the equipment moves to detect the side leakage of the pipeline, the gear rotates, and the half-ring gear ring on one side of the meshing causes the detection head to rotate, so that the detection head surrounds the pipeline to detect the side leakage.
[0016] The beneficial effects of the utility model are:
[0017] After the two fixed half rings are installed on the outer wall of the pipeline, the motor is started to make the roller roll on the outer wall of the pipeline, thereby driving the entire device to slide along the pipeline. During the sliding process, the detection head measures the leakage point on the outer wall of the pipeline below. At the same time, under the action of the driving bevel gear on one side of the main shaft and the driven bevel gear, the gear meshing half ring gear at one end of the secondary shaft drives the detection head to rotate along the outer wall of the pipeline, thereby performing a 360-degree detection of the outer wall of the pipeline without blind spots, so that the device can move and rotate on the outer wall of the pipeline by itself during operation, so that the detection head can measure the leakage point of the pipeline without blind spots, thereby improving the accuracy of detection and increasing efficiency.
