[0019] Beneficial effects of the present invention:

[0020] 1. The present invention uses a bidirectional electric push rod to drive the toothed plate to move and engage with the gear, thereby driving the winding seat to wind up the pull rope. In the initial state, the vertical plate is vertical, and the baffle of the vertical pipe blocks the opening of the horizontal pipe at the lower end of the connecting pipe.

In this structure, the disassembly and assembly of the bottom box and the installation of the detection component are convenient. At the same time, the traction force of the pull rope can be used to connect with the monitoring pipe at a farther distance, and the water flow direction can be switched simultaneously from both ends of the connecting pipe. This has little effect on the installation distance of the monitoring pipe and the length of the connecting pipe, and can meet the installation requirements of connecting pipes of different lengths, and can switch the object for detecting leakage.

[0022] 3. The Cat.1 water meter body of the present invention is threadedly connected to the connecting pipe and the monitoring pipe through a connecting end, a connecting head and an installation end, and adopts an existing connection method, which is convenient for installation, disassembly and replacement. The first flow sensor and the second flow sensor inside the Cat.1 water meter body and the monitoring pipe are flow sensors of the same type, and the water flow is detected at different points, so it is more convenient to determine the location of the leak.

[0023] 4. Compared with the prior art, the present invention additionally sets monitoring tubes at both ends of the Cat.1 water meter, collects three sets of water flow data through the cooperation of the second flow sensor in the monitoring tube and the first flow sensor inside the Cat.1 water meter, and compares them. The leakage position is simply determined based on the comparison data results, and the leakage position is accurately found through the detection component, so that timely maintenance can be carried out to reduce the waste of water resources.

The water flows along the horizontal pipe at the lower end into the Cat.1 water meter body 1. When comparing the data values ​​of the flow sensor inside the monitoring tube 4 and the Cat.1 water meter body 1, it is still When there is a difference, it is determined that the Cat.1 water meter body 1 is leaking, and the staff is notified in time to carry out maintenance and replacement to avoid affecting the recording of the flow value. When the data values ​​are the same or the difference is small, it means that there is a leak in the connecting pipe 3, and the residents are notified to repair or replace the connecting pipe 3 by themselves to maintain normal water flow delivery. The detection coordination between one side of the output end and the Cat.1 water meter body 1 is the same. The two-way electric push rod 29 can select the side with the abnormality to switch the water flow direction, and can also simultaneously start the connecting pipes 3 on both sides to switch the flow direction.
