TECHNICAL FIELD
[0001] The present application relates to the technical field of water pipe control, and is a clean water distribution system. BACKGROUND
[0002] In the existing water supply system, components such as water pipes, joints, and valves are mainly used. In particular, in the clean water supply system, open pipes, i.e., pipes exposed to the indoor environment, are usually used. When the water pipes are laid between floors, between rooms on the same floor, and between rooms in a room, many joints and valves are used. The service life of the water pipes is relatively long, generally exceeding 50 years, and damage and water leakage are not easy to occur. However, the service life of the joints and valves is relatively short, and the joints and valves are located at the connection positions of the water pipes. The sealing performance of the joints and valves is affected by the installation process. After being used for a period of time, the joints and valves are prone to water leakage. Not only is the clean water wasted, but the water leakage also damages other equipment or flows into the cabinet or the floor, causing huge property losses. If the water leakage of the existing water supply system is not found in time, great losses are likely to occur. After the water leakage is found, the rough management of closing the main valve is usually used for maintenance, which affects the normal water use in other areas. SUMMARY

[0024] Further, the water leakage sensor is installed at the joint of each level of water pipe. The detection end of the water leakage sensor is installed at the position to be detected, which can be the joint of each level of water pipe or other positions prone to water leakage.
[0025] Further, the electrically controlled valve is an electric valve. The electric valve generally comprises an electric actuator and a valve. The electric valve uses electric energy as power to drive the valve through the electric actuator to realize the opening and closing action of the valve, so as to achieve the opening and closing purpose of the pipeline medium. The electric valve has fast opening and closing action, simple structure and easy maintenance.
[0026] Further, the electrically controlled valve is a normally open electric valve.
[0027] Further, the clean water distribution pipe network comprises a primary water pipe 1, a plurality of secondary water pipes 2 are connected in parallel on the primary water pipe, and a plurality of tertiary water pipes 3 are connected in parallel on each secondary water pipe. The clean water distribution pipe network can set multiple levels of water pipes according to specific use requirements.
[0028] Further, the sound and light alarm 5 is further included, and the instruction output end of the central controller is electrically connected with the instruction input end of the sound and light alarm. After the central controller detects water leakage of a certain node, the sound and light alarm is triggered to remind the maintenance personnel to repair in time.
[0029] Further, the clean water storage device 6 is further included, and the water outlet of the clean water storage device is communicated with the water inlet of the clean water distribution pipe network. The clean water storage device can be a clean water tank or a clean water tank, which is communicated with the clean water distribution pipe network through a water pump.
[0030] Further, the water leakage point display 7 is further included, and the signal output end of the central controller is electrically connected with the signal input end of the water leakage point display. The water leakage point display can accurately display the node where water leakage occurs, which is the existing publicly known technology and can be purchased on the market. For details, refer to the large screen in the factory control room.
[0031] The working principle of the present application is as follows:
[0032] The embodiment takes a water distribution pipe network formed by three levels of water pipes as an example for illustration. The clean water storage device 6 is communicated with the inlet of the first level water pipe through the water pump 22. The first level water pipe is provided with the first water leakage sensor 8 and the first electric control valve 15. The outlet of the first level water pipe is communicated with two second level water pipes. One of the two second level water pipes is provided with the second water leakage sensor 9 and the second electric control valve 16. The other second level water pipe is provided with the third water leakage sensor 10 and the third electric control valve 17. The outlets of the two second level water pipes are respectively communicated with two third level water pipes. The first third level water pipe is provided with the fourth water leakage sensor 11 and the fourth electric control valve 18. The second third level water pipe is provided with the fifth water leakage sensor 12 and the fifth electric control valve 19. The third third level water pipe is provided with the sixth water leakage sensor 13 and the sixth electric control valve 20. The fourth third level water pipe is provided with the seventh water leakage sensor 14 and the seventh electric control valve 21. The ends of the four third level water pipes are respectively provided with water using devices 23.
[0033] The first step is monitoring. The water leakage sensors of the nodes monitor the water leakage state of the water pipes in real time.
[0034] The second step is transmission. The water leakage sensor of a node that detects water leakage immediately sends a signal to the central controller.
[0035] The third step is judgment. The central controller locks the corresponding water using branch water pipe according to the signal.
[0036] The fourth step is execution. The central controller only closes the electric control valve of the water leakage branch to cut off the water source of the water leakage point, and other electric control valves remain open. The central controller triggers the sound and light alarm to alarm. The central controller sends alarm information containing the water leakage position to the user. The central controller displays the water leakage position on the water leakage point display.
[0037] If the fourth water leakage sensor detects a water leakage signal, the water leakage signal is sent to the central controller in real time. The central controller locks the corresponding first third level water pipe according to the position of the fourth water leakage sensor. Meanwhile, the central controller sends a control instruction to close the fourth electric control valve to cut off the water source of the water leakage point, and other electric control valves remain open. The central controller triggers the sound and light alarm to alarm. The central controller sends alarm information containing the water leakage position to the user. The central controller displays the water leakage position on the water leakage point display.
[0038] The present application modularly partitions and manages the clean water distribution system like a circuit, independently controls each water using branch through the central controller, only closes the branch where the water leakage point is located when water leakage, does not affect the normal water use of other areas, realizes accurate fault isolation, adopts the cooperative working mode of distributed water leakage sensor detection and centralized decision of the central controller, and is fast and reliable in response.
[0039] The above description is only an example for clearly illustrating the present application, and is not a limitation on the embodiments of the present application. Any obvious changes or variations derived from the technical solutions of the present application are still within the protection scope of the present application.
