The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the water-saving environment-friendly intelligent water tank water supply system according to the embodiment includes a set of control device, a plurality of water tanks, and a disinfection device. The sterilization and disinfection device comprises an ozone generator and a hot air dryer, the control device is a PLC (programmable logic controller) in the prior art, the water tank is a container for storing water, and the number of the water tanks is preferably three.

The water inlet valves are connected to a water source, the water supply valves are connected to water consumption points, the drain valves and the return valves are simultaneously connected to a pipeline, and a water suction pump is arranged between the drain valves and the return valves of the pipeline. In addition, the water tank is also provided with a plurality of pipelines for connecting the electromagnetic valves, and the pipelines comprise a water inlet pipe 1, a water outlet pipe 2, a water supply pipe 3, an overflow pipe 4, an air supply pipe 6 and an oxygen supply pipe 5.
One end of the water inlet pipe 1 is connected to a water source, such as a municipal water source. The other end of the water inlet pipe is connected with the water inlet valve of each water tank, so that each water inlet valve is formed as shown in the attached figure 1, and is connected with a water source in parallel through the connection of the water inlet pipe 1.
The drain pipe 2 is a pipe that connects the drain valves and the return valves at the same time, one end of the drain pipe 2 is connected to the drain valves of the water tanks, and the other end of the drain pipe 2 is connected to the return valves of the water tanks. Similarly, the connections are such that the return valves are connected in parallel with the discharge valves by the connection of the discharge pipe 2 as shown in fig. 1. Further, the drain pipe 2 is provided with a suction pump between each of the drain valves and each of the return valves. After the drainage valve is opened, water in the water tank can be pumped to the return valve at the upper end of the water tank from bottom to top by the pumping of the water pump and falls back into the other water tanks.
One end of the water supply pipe 3 is connected to the water supply valve of each of the water tanks, and the other end of the water supply pipe 3 is connected to a water consumption point, and likewise, the connection is such that each of the water supply valves is formed as shown in fig. 1, and the connection through the water supply pipe 3 is connected in parallel to the water consumption point.

In addition, the upper end of the water tank is also provided with an air outlet 8, and the air outlet 8 is used for discharging hot air, so that the phenomenon that the hot air dryer continuously inputs hot air flow to cause overhigh air pressure in the water tank is avoided. Further, for the convenience of controlling the opening and closing of the air outlet 8, the air outlet 8 may also be an electromagnetic valve controlled by the control device.
One end of the oxygen supply pipe 5 is connected to the ozone output end of the ozone generator, and the other end of the oxygen supply pipe 5 is connected to the ozone valve of each water tank.

In addition, the water supply system also comprises a plurality of alarm units, an overflow sensor is arranged in the water tank, the alarm units can be buzzers, and each alarm unit corresponds to the overflow sensor of one water tank. The overflow sensor is fixed to the side surface below the upper pipe orifice of the overflow pipe 4, and when the water level is at the position of the overflow sensor, the overflow sensor is triggered and a signal is output. The overflow sensor is electrically connected to the control device, the control device receives signals of the overflow sensor and then controls the corresponding alarm unit to work, the alarm is used as a warning to remind workers that water in the water tank is higher than the overflow sensor, namely higher than a warning line, so that the workers can check the water tank in real time conveniently, simultaneously close a water inlet valve and a water supply valve of the corresponding water tank, and start the water tank after faults are eliminated.
In addition, the lower end in the water tank is also provided with a low water level sensor, the upper end in the water tank is provided with a high water level sensor, the low water level sensor and the high water level sensor are consistent with the overflow sensor and are water level sensors for sensing water levels, the water level sensors and the high water level sensors are electrically connected to the control device, and the control device controls the opening and closing of the electromagnetic valves and the opening and closing of the water pump, the ozone generator and the hot air dryer after receiving signals of the water level sensors and the high water level sensors, so that the whole water supply system works.
Specifically, the working method of the clean and environment-friendly intelligent water tank water supply system comprises the following steps:
closing the drain valves, the inlet valves and the water supply valves of all the water tanks, and opening the water supply valves of the water tanks one by one for supplying water, wherein the one-by-one opening mode is that when one water tank with the opened water supply valve supplies water to a low water level (namely, the position of the low water level sensor), the water supply valve of the water tank is closed, and then the water supply valve of any one of the rest water tanks without supplying water is opened. Taking fig. 1 as an example, when the first water tank is supplied with water to the lowest level, the water supply valve of the first water tank is closed, and the water supply valve of the second water tank is opened only; when the second water tank supplies water to the low water level, the water supply valve of the second water tank is closed, and simultaneously, only the water supply valve of the third water tank is opened, so that all the water tanks can realize water supply in sequence, and after the water tank supplies water to the low water level, the water tanks also sequentially perform the work of drainage, disinfection and water storage.
The drainage work is as follows:
when the water supply of the water tank is reduced to a low water level point and the water supply valve of the water tank is closed, the drain valve of the water tank is opened, the water suction pump is started, and meanwhile, only the return valve of the next water tank to be supplied with water is opened, so that the residual water at the bottom of the water tank in the water supply can be quickly discharged into the next water tank through the drain pipe 2 until the residual water at the bottom of the water tank is discharged into the first water tank for supplying water after the last water tank is reached. The way of rapidly discharging the residual water in the water tank to the next water tank to be supplied with water can avoid the waste of water resources.
Continuing to take the example of fig. 1 and referring to fig. 3, when the first water tank supplies water to a low water level point, the low water level sensor is triggered, the low water level sensor transmits a signal to the control device, the control device receives the signal, closes the water supply valve of the first water tank, opens the drain valve of the first water tank, opens the reflux valve of the second water tank, and starts the water pump to pump the residual water in the first water tank into the second water tank; when the second water tank supplies water to a low water level point, similarly, after the control device receives a signal of a low water level sensor of the second water tank, the control device controls to close a water supply valve of the second water tank, open a drain valve of the second water tank, open a return valve of the third water tank and start a water suction pump so as to pump the residual water in the second water tank into the third water tank; when the third water tank supplies water to a low water level point, similarly, after the control device receives a signal of a low water level sensor of the third water tank, the control device controls to close a water supply valve of the third water tank, open a drain valve of the third water tank, simultaneously open a return valve of the first water tank and start a water suction pump, so that the residual water in the third water tank can return to the first water tank. It can be seen that this mode of discharging the remaining water in the water tank bottom of water supply in the water tank to next water supply in a quick manner is equivalent to the quick drainage of the water in the water tank to the follow-up disinfection and sterilization work to the water tank can avoid the user to temporarily not have water, cause to leave remaining water in the water tank and the problem that can't be timely carry out disinfection and sterilization to the water tank.
The disinfection and sterilization work is as follows:
after the water tank finishes draining, the water suction pump is closed, the hot air valve and the air outlet 8 are opened, the hot air dryer is started, and hot air is conveyed into the water tank through the air supply pipe 6 to be disinfected at high temperature. After the high-temperature sterilization is finished, the hot air valve and the air outlet 8 are closed, the hot air dryer is closed, the ozone valve is opened, the ozone generator is started, ozone ions generated by the ozone generator are conveyed into the water tank through the oxygen conveying pipe 5, and ozone sterilization is carried out. Wherein the time of sterilization and disinfection can be controlled by the control device. Specifically, the control device controls the operation time of the hot air dryer and the opening and closing time of the air supply valve and the air outlet, and controls the operation time of the ozone generator and the opening and closing time of the oxygen supply valve.
Taking the first water tank in the attached drawing 1 as an example and referring to the attached drawing 4, when the first water tank finishes draining, the water suction pump is closed, the hot air dryer is started, the hot air valve and the exhaust port of the first water tank are opened simultaneously, after drying is finished, the hot air valve and the exhaust port are closed, the hot air dryer is automatically closed, the ozone generator and the ozone valve are started simultaneously, and after disinfection is finished, the ozone generator and the ozone valve are closed. Through the mode, the water tanks can automatically realize disinfection and sterilization after water supply is finished, and when one water tank is in the disinfection and sterilization process, other water tanks can supply water without influencing water supply to users.
The water storage process comprises the following steps:
after the water tank finishes disinfection and sterilization, the water inlet valve of the water tank is opened, so that water flows into the water tank through the water inlet pipe 1, and when the water level is higher than the high water level sensor, the water inlet valve of the water tank is closed, so that the water storage of the water tank is finished. Wherein the time for opening the water inlet valve after the completion of the sterilization is controlled by the control device. Furthermore, the control device can realize water storage in different periods according to the water usage habit of each building so as to reduce the storage time of water in the water tank, thereby relieving the pressure of water supply companies, improving the mobility and quality of water, further avoiding secondary pollution of water and avoiding waste of water resources.
Continuing to take the first water tank in fig. 1 as an example, when the first water tank needs to store water, only the water inlet valve of the first water tank is opened, when the high water level sensor of the first water tank stores water, the high water level sensor is triggered, the high water level sensor transmits a signal to the control device, and the control device receives the signal and then controls the water inlet valve to be closed, so that water supply of the first water tank can be completed. By the method, water storage of each water tank can be automatically completed after disinfection and sterilization.
In conclusion, the intelligent water tank system can realize automatic drainage, disinfection and storage after water is supplied to each water tank, and when one water tank is in the processes of drainage, disinfection and storage, other water tanks can supply water, which is equivalent to the intelligent water tank water supply system of the invention that water can be always supplied, and meanwhile, the interior of each water tank can be always kept in a clean state, so that secondary pollution of water can be avoided, and the water quality is improved.
