Description

Technical Field

[0001] The utility model relates to the technical field of water supply pipe network leakage detection, in particular to a water supply pipe network leakage detection device. Background Art

[0002] A water pipe leak detector (also called a water leak detector) is a device used to detect the location of water pipe leaks. The water pipe leak detector is based on sound detection technology. When there is a leak in the water pipe, the water flowing out will produce a specific sound frequency. The water pipe leak detector can determine the location of the leak by receiving and analyzing these sound signals. By moving the leak detector close to the pipe, the operator can determine the approximate location of the leak according to the indication on the instrument or the sound prompt.

[0003] The existing Chinese patent with publication number CN218599482U discloses a water supply network leak detection device, which relates to the field of water supply network leak detection technology, including a detector body, the ground of the detector body is symmetrically provided with support rods, the top of the support rods is rotatably connected to the detector body, and an electric drive wheel is provided on the opposite side of the bottom end. First, the support rod is opened by an adjustment mechanism, and then the support rod is clamped to the pipe body to be detected by the adjustment mechanism, so that the support rod holds the pipe body to be detected, and the installation of the detector body on the pipe body to be detected is completed. Then, the electric drive wheel rolls after power is supplied, driving the support rod and the detector body to move on the pipe body to be detected, so as to realize automatic detection of the pipe body. When encountering a pipe connection, the opening degree of the support rod can be adjusted by the adjustment mechanism so that the electric drive wheel can pass over the pipe diameter change position to realize barrier-free passage, which is very suitable for pipe leak detection in high places and dangerous areas.

[0004] With regard to the above-mentioned related technologies, the opening degree of the support rod is used to make the electric drive wheel close to the pipeline. However, in actual use, the toughness of the support rod has a certain service life. After long-term use, the support rod itself is fragile, making it difficult for the electric drive wheel to close to the outer wall of the pipeline, thereby affecting the possibility of moving the device.

[0005] Therefore, we propose a water supply pipe network leak detection device to solve the above-mentioned problems. Utility Model Content
