Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water meter leakage detection, in particular to a split-mounted prepayment water meter leakage detection device. BACKGROUND

[0002] The water meter leakage detection device is a device for detecting whether there is a leakage phenomenon in the water pipe system, which is usually used in combination with a water meter. This device can monitor the water flow, identify and locate the leakage point, so as to help discover the leakage problem in time and repair it, avoiding the waste of water resources and property loss.

[0003] The patent with the patent announcement number CN203869812U relates to the technical field of water meter leakage detection, and provides a water meter leakage detection device, which comprises a water pipe slide rail, a sliding block and a detection box. The sliding block is sealingly and slidingly assembled with the water pipe slide rail. The water pipe slide rail is designed with a through hole on the wall surface of the sliding block, which is in communication with the detection box. One end of the sliding block is connected through a spring. One end of the detection box is in communication with the output water pipe. An observation window made of transparent material is designed on the detection box, through which the sliding block can be observed. The device is installed in the waterway. If there is no leakage in the waterway, the spring pushes the sliding block to close the through hole. When there is a leakage in the detection part of the pipeline, the water pressure pushes the sliding block to compress the spring, so that the through hole connects the water pipe slide rail and the detection box, and water seeps out. At this time, the leakage can be easily observed from the observation window.

[0031] The detection anti-blocking mechanism comprises a rotating rod 7, a fixed plate 8, a fixed rod 9, a sliding rod 10, an elastic telescopic rod 11, a sealing ring 12, an L-shaped rod 13, a fixed block 14, a clamping block 15 and a long rod 16. The rotating rod 7 is rotatably penetrated through the dial 5. The fixed plate 8 is fixedly installed on the circumferential surface of the rotating rod 7. The fixed rod 9 is fixedly installed on the inner wall of the water outlet pipe 3. The sliding rod 10 is slidably penetrated through the fixed rod 9. The elastic telescopic rod 11 is fixedly installed on the circumferential surface of the inner wall of the connecting pipe 4. The sealing ring 12 is fixedly installed on the movable end of the elastic telescopic rod 11. The L-shaped rod 13 is fixedly installed on one end of the sealing ring 12 close to the movable end of the elastic telescopic rod 11. The fixed block 14 is fixedly installed on the top of the outer wall of the connecting pipe 4. The clamping block 15 is slidably installed in the fixed block 14. The long rod 16 is fixedly installed on the top of the clamping block 15. The sliding rod 10 is repeatedly pushed in the connecting pipe 4 by the fixed plate 8, so that the deposition, sundries or dirt cannot accumulate in the pipeline, the possibility of pipeline blockage is reduced, the water flow in the pipeline is kept smooth, and the accuracy of the water meter is improved.

[0032] The end of the sliding rod 10 close to the fixed plate 8 is provided with an inclined surface. A spring 1 is arranged between the sliding rod 10 and the fixed rod 9. A spring 2 is arranged between the clamping block 15 and the fixed block 14. The sliding rod 10 can be smoothly pushed by arranging the inclined surface. The sliding rod 10 can be automatically reset by arranging the spring 1. The clamping block 15 can be automatically reset by arranging the spring 2.

[0033] In the working of the embodiment, first, the staff checks the working state of the meter body 1 before installing the meter body 1, and installs the meter body 1 at the designated position after confirming that the working state is normal. The water inlet is connected with the water inlet pipe 2, and the water outlet is connected with the water outlet pipe 3. After the connection is completed, the water valve is opened to start water flow. The water flow impacts the fixed plate 8 inside the meter body 1, the fixed plate 8 drives the rotating rod 7 to start rotating, the rotating rod 7 drives the pointer to rotate, and the pointer rotates on the dial 5 to display the reading, so that the staff knows the amount of water used. At the same time, the water flow impacts the leakage detection device 6 after passing through the meter body 1, and the leakage detection device 6 judges whether the current meter body 1 is working normally and whether there is leakage through the impact of the water flow and the size of the water pressure. Through the leakage detection device, the leakage problem in the water meter or pipeline system can be found in time, unnecessary waste of water resources is avoided, and the user's water fee expenditure is reduced. At the same time, the timely feedback of the leakage detection device can help the user and the property or maintenance personnel find the leakage point as soon as possible and repair the leakage problem in time. While the fixed plate 8 rotates, it contacts and pushes the sliding rod 10 to start moving forward. The sliding rod 10 moves forward to stretch the spring 1 between the fixed rod 9. After the fixed plate 8 no longer contacts and pushes the sliding rod 10, the sliding rod 10 starts to move backward to reset under the action of the spring 1. The sliding rod 10 repeatedly moves inside the connecting pipe 4 through the repeated pushing of the fixed plate 8, so as to ensure that the sediments, sundries or dirt cannot accumulate in the pipeline, reduce the possibility of pipeline blockage, ensure the smooth flow of water in the pipeline, and help improve the accuracy of the water meter. While the sliding rod 10 moves forward, it contacts and pushes the L-shaped rod 13 to start moving forward. The L-shaped rod 13 moves forward to drive the sealing ring 12 to start moving forward. When it is necessary to remove the sealing ring 12, the staff manually pulls the long rod 16 to make the long rod 16 drive the clamping block 15 to move upward. After the clamping block 15 moves upward to release the restriction on the sealing ring 12, the sealing ring 12 starts to move to reset under the action of the movable end of the elastic expansion rod 11. After the sealing ring 12 moves forward and the clamping block 15 is no longer restricted, it starts to move downward under the action of the spring 2. Then, the sealing ring 12 starts to reset to clamp the clamping block 15 under the action of the movable end of the elastic expansion rod 11, so that the sealing ring 12 is always fixed between the connecting pipe 4 and the connecting pipe during work. The sealing ring 12 moves forward to seal the gap between the connecting pipe 4 and the connecting pipe, effectively filling the gap between the water meter and the connecting pipe 4, ensuring that the water pipe connection does not leak, and preventing water from leaking out of the connection.
