[0002] As a new form of drinking water, piped drinking water is developing rapidly across the country. The deep treatment of raw water is achieved through membrane components to achieve the purpose of direct drinking. In order to meet the user's water consumption peak, the drinking water treated by the piped drinking water system will be temporarily stored in a pure water tank, and the circulating pump will distribute and supply the water. However, as a water storage device, the pure water tank is an important part of the piped drinking water system. The water level signal setting and control linkage method are particularly important. Improper settings will cause hidden dangers such as insufficient water and water outage or water overflow, which will not only affect the reliability of the entire system operation, but also directly affect the user experience. In order to avoid such problems, it is necessary to invent an intelligent water production and water supply and allocation control system for piped drinking water, which can sense the liquid level in real time and accurately regulate the liquid level in real time to meet user needs while being economical and applicable.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides a piped drinking water production and supply intelligent allocation control system, including a clean water tank 1, a water injection pipe 2 is fixedly installed on the surface of the clean water tank 1, a bracket 3 is fixedly installed inside the water injection pipe 2, a telescopic rod 4 is fixedly installed on the side of the bracket 3 away from the clean water tank 1, a spring 5 is sleeved on the surface of the telescopic rod 4, a sealing sheet 6 is fixedly installed on the side of the spring 5 away from the bracket 3, and a limit ring 7 is fixedly installed inside the clean water tank 1.

[0021] The diameter of the sealing sheet 6 is greater than the inner diameter of the limiting ring 7. Its main function is to fit the sealing sheet 6 with the limiting ring 7. When the inside of the water purification pool 1 is filled with water, the water will remain stationary for a long time to prevent the water inside the water purification pool 1 from flowing back, thereby causing the water that has been stationary to continue to be disturbed.

[0022] Among them, a pure water injection pipe 8 is fixedly installed on the side of the pure water tank 1 away from the water injection pipe 2, and a control valve 1 9 is rotatably connected inside the pure water injection pipe 8. A pure water tank 10 is fixedly installed on the surface of the pure water injection pipe 8, and a water supply pipe 11 is fixedly installed on the bottom of the pure water tank 10. A circulating water pump 12 is fixedly installed on the surface of the water supply pipe 11, and a water reservoir 13 is fixedly installed on the surface of the circulating water pump 12. A user water pipe 14 is fixedly installed on the surface of the water reservoir 13, and a return pipe 15 is fixedly installed on the surface of the water reservoir 13. The return pipe 15 is rotatably connected inside with a control valve 2 16.

[0023] The reflux pipe 15 is fixedly connected to the pure water tank 10. When the water that has been standing is injected into the pure water tank 10 through the pure water injection pipe 8, it is pumped by the circulating water pump 12 and injected into the water reservoir 13, and then dispersed into the user's water pipe 14, thereby achieving the water supply effect.

[0024] Among them, a data line 17 is fixedly installed on the surface of the circulating water pump 12, a PLC control system 18 is fixedly installed on a section of the data line 17 away from the circulating water pump 12, a data line 20 is fixedly installed on the surface of the PLC control system 18, and a solenoid valve 19 is fixedly installed on the side of the data line 20 away from the PLC control system 18.

[0025] The solenoid valve 19 is located inside the water injection pipe 2 , and its main function is to close and open the inside of the water injection pipe 2 in time by being controlled by the PLC control system 18 , so as to achieve the effect of injecting water into the water purification pool 1 .

[0026] Among them, a water level monitoring tube 21 is fixedly installed at the bottom of the pure water tank 10, an electronic liquid level meter 22 is fixedly installed on the surface of the water level monitoring tube 21, and a data line 3 23 is fixedly connected to the surface of the electronic liquid level meter 22.

[0027] Data line three 23 is connected to the PLC control system 18. When the electronic liquid level meter 22 detects that the water level is too low, the PLC control system 18 is used to promptly control the clean water pool 1, so that the water source inside the clean water pool 1 is promptly injected into the pure water tank 10 to achieve the purpose of water storage.

[0028] Among them, the interior of the pure water tank 10 is fixedly installed with a high alarm liquid level h324, a water production stop liquid level h225, a water production start liquid level h126, a circulation pump start liquid level h327, a low alarm liquid level h228, a circulation pump stop liquid level h129 and a minimum liquid level h30.

[0029] The main function of the high alarm liquid level h324 to the minimum liquid level h30 is to monitor the water level inside the pure water tank 10 in real time to prevent overflow due to excessive water level and prevent the water level from being too low and not being replenished in time.

[0030] There are multiple user water pipes 14 , and all of the multiple user water pipes 14 are located on the right side of the water reservoir 13 . The water reservoir 13 , the return pipe 15 and the pure water tank 10 are fixedly connected.

[0031] The main function of the return pipe 15 is that when the water inside the water reservoir 13 is not used up by the user water pipe 14, it will flow back through the return pipe 15, thereby achieving the effect of recycling water resources.

[0032] The working principle and use process of this utility model:

[0033] First, set a total of 6 liquid level values ​​for the pure water tank 10 level gauge: circulating pump stop level h129, low alarm level h228, circulating pump start level h327, water production start level h126, water production stop level h225, high alarm level h324,

[0034] The lowest liquid level h30 is located at the bottom of the side of the pure water tank 10, keeping a certain distance from the water inlet. The circulating pump stop level h129: 100-150mm higher than the "lowest liquid level", making full use of the pure water in the water tank; the low alarm level h228: 150-200mm higher than the "circulating pump stop level h129", leaving a certain buffer time after the system alarm; the circulating pump start level h327: about 300mm higher than the "low alarm level h228", the water storage volume in the water supply and return pipe network needs to be considered; the water production start level h126: 150-200mm lower than the "water production stop level h225", avoiding frequent start-up of the water production system. The high alarm level h324: the high liquid level of the water tank, 150-200mm lower than the highest height of the water tank, and the water storage volume in some return pipe networks also needs to be considered.

[0035] Finally, when the liquid level is lower than the circulating pump stop level h129, the electronic liquid level meter 22 senses and obtains a low liquid level signal, which is transmitted to the PLC control system 18 through the signal processor. After the PLC control system 18 senses the signal, it outputs a judgment signal to the outside and stops driving the circulating water pump 12 to work;

[0036] When the liquid level is lower than the low alarm level h228, the electronic liquid level meter 22 senses and obtains the liquid level signal at the same time, and transmits it to the PLC control system 18 through the signal processor. After the PLC control system 18 senses the signal, it outputs a judgment signal to the outside, the system alarms, and the background displays a low liquid level alarm. Manual intervention is required to find out the cause;

[0037] When the liquid level is higher than the circulating pump start level h327, the electronic liquid level meter 22 senses and obtains the liquid level signal, which is transmitted to the PLC control system 18 through the signal processor. After the PLC control system 18 senses the signal, it outputs a judgment signal to drive the circulating water pump 12 to work.

[0038] When the liquid level is lower than the water production start level h126, the liquid level meter senses and obtains the liquid level signal, which is transmitted to the PLC control system 18 through the signal processor. After the PLC control system 18 senses the signal, it outputs a judgment signal to the outside, opens the solenoid valve 19, and starts the water purification process;

[0039] When the liquid level is higher than the water production stop level h225, the electronic liquid level meter 22 senses and obtains the liquid level signal, which is transmitted to the PLC control system 18 through the signal processor. After the PLC control system 18 senses the signal, it outputs a judgment signal to the outside, closes the water purification tank 1, and closes the water inlet solenoid valve 19;

[0040] When the liquid level is higher than the high alarm level h324, the electronic liquid level meter 22 senses and obtains the liquid level signal at the same time, and transmits it to the PLC control system 18 through the signal processor. After the PLC control system 18 senses the signal, it outputs a judgment signal to the outside, the system alarms, and the background displays a low liquid level alarm. Manual intervention is required to find out the cause.
