Description

Technical Field

[0001] The utility model belongs to the technical field of the design and maintenance of secondary water supply facilities for public buildings and residential communities, and particularly relates to a water-saving cleaning device for a domestic water tank. Background Technique

[0002] The way of supplying water by adding a variable frequency water pump to the domestic water tank is widely used in the secondary water supply system of public buildings and residential communities. To ensure the safety and hygiene of domestic water, we need to take strict maintenance measures. One of them is to thoroughly clean and disinfect the domestic water tank regularly. This not only helps to remove the dirt, scale and microorganisms that may accumulate on the inner wall of the water tank, but also can effectively prevent water quality from being polluted, thus ensuring that residents can drink clean and healthy water sources.

[0003] In the conventional maintenance process of the domestic water tank, there is usually a necessary step before cleaning the water tank, that is, completely emptying the water in the water tank. However, a large amount of tap water stored water is thus discharged without reason during this process, which is undoubtedly a great waste of precious water resources. This traditional practice not only increases the consumption of water resources, but also causes an unnecessary burden on the environment;

[0004] In addition, since the domestic water tank needs to ensure the safety and cleanliness of water quality, this requires that the staff must carry out cleaning work regularly. However, this periodic maintenance and cleaning work not only increases the demand for manual labor, but also increases the operation cost. Frequent cleaning tasks mean that the staff needs to invest a lot of time and energy in the cumbersome cleaning and disinfection work, and the labor is large. Content of the Utility Model

[0005] The purpose of the utility model is to provide a water-saving cleaning device for a domestic water tank to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A water-saving cleaning device for a domestic water tank, comprising:

[0008] A water tank one, a water tank two and a central controller;

[0009] A first inlet pipe solenoid valve is installed on the outer surface of the inlet pipe of the water tank one, a first remote transmission liquid level gauge is installed at one end of the water tank one, and a first outlet pipe solenoid valve is installed on the outer surface of the outlet pipe of the water tank one;

[0010] A second inlet pipe solenoid valve is installed on the outer surface of the inlet pipe of the water tank two, a second remote transmission liquid level gauge is installed at one end of the water tank two, and a second outlet pipe solenoid valve is installed on the outer surface of the outlet pipe of the water tank two;

[0011] A variable-frequency water supply device is jointly connected between the second outlet pipe solenoid valve and the first outlet pipe solenoid valve, and a water tank connecting pipe solenoid valve is jointly installed between the first water tank and the second water tank;

[0012] The first inlet pipe solenoid valve, the first remote liquid level gauge, the first outlet pipe solenoid valve, the second inlet pipe solenoid valve, the second remote liquid level gauge, the second outlet pipe solenoid valve, the water tank connecting pipe solenoid valve, and the variable-frequency water supply device are all electrically connected to the central controller.

[0013] Preferably, one end of the first remote liquid level gauge penetrates through the first water tank and extends into the first water tank, and one end of the second remote liquid level gauge penetrates through the second water tank and extends into the second water tank.

[0014] Preferably, the inlet pipes of the first water tank and the second water tank are both connected to the municipal tap water pipe.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] (1) A water tank inlet and outlet automatic control system is composed of the first inlet pipe solenoid valve, the first remote liquid level gauge, the first outlet pipe solenoid valve, the second inlet pipe solenoid valve, the second remote liquid level gauge, the second outlet pipe solenoid valve, the water tank connecting pipe solenoid valve, the variable-frequency water supply device, and the central controller. Before cleaning, the variable-frequency water supply device only pumps water from the first water tank for water supply, reducing the emptying drainage volume during the cleaning of the first water tank. At the same time, the inlet and outlet automatic control system provided by this part of the equipment can realize the function of the variable-frequency water supply device pumping water from the second water tank to ensure the domestic water use of residents when the first water tank is cleaned. Only a small amount of water remains in the first water tank, and this water is sufficient for the cleaning work. A period of time before the scheduled water tank cleaning time, the valve action is controlled through a predetermined program to pressurize the tap water in the water tank to be cleaned for residents to use, reducing the ineffective emptying discharge, thereby reducing the amount of water discharged due to the emptying of the water tank during cleaning and reducing the waste of water resources.

[0017] (2) By setting the central controller to control the equipment, through precise control of the operation and monitoring of the equipment, an automated cleaning and maintenance process is realized, thereby greatly reducing the burden of manual operation and the time of the manual maintenance and cleaning cycle, and at the same time facilitating the maintenance and cleaning of the water tank.

[0021] Embodiment 1:

[0022] Please refer to Figure 1 As shown, a water-saving cleaning device for a domestic water tank includes:

[0023] A first water tank 3, a second water tank 7 and a central controller 11;

[0024] An outer surface of the water inlet pipe of the first water tank 3 is provided with a first water inlet pipe solenoid valve 1. One end of the first water tank 3 is provided with a first remote liquid level gauge 2. An outer surface of the water outlet pipe of the first water tank 3 is provided with a first water outlet pipe solenoid valve 4;

[0025] An outer surface of the water inlet pipe of the second water tank 7 is provided with a second water inlet pipe solenoid valve 5. One end of the second water tank 7 is provided with a second remote liquid level gauge 6. An outer surface of the water outlet pipe of the second water tank 7 is provided with a second water outlet pipe solenoid valve 8;

[0026] A frequency conversion water supply device 10 is commonly connected between the second water outlet pipe solenoid valve 8 and the first water outlet pipe solenoid valve 4. A water tank connecting pipe solenoid valve 9 is commonly installed between the first water tank 3 and the second water tank 7;

[0027] The first water inlet pipe solenoid valve 1, the first remote liquid level gauge 2, the first water outlet pipe solenoid valve 4, the second water inlet pipe solenoid valve 5, the second remote liquid level gauge 6, the second water outlet pipe solenoid valve 8, the water tank connecting pipe solenoid valve 9 and the frequency conversion water supply device 10 are all electrically connected to the central controller 11.

[0028] As Figure 1 can be seen, one end of the first remote liquid level gauge 2 penetrates through the first water tank 3 and extends into the first water tank 3. One end of the second remote liquid level gauge 6 penetrates through the second water tank 7 and extends into the second water tank 7; The water inlet pipes of the first water tank 3 and the second water tank 7 are both connected to the municipal tap water pipe.

[0029] As can be seen from the above, the water inlet pipes of water tank 1-3 and water tank 2-7 are connected to the municipal tap water pipe, so as to supply water to residents. The first remote liquid level gauge 2 and the second remote liquid level gauge 6 can be used to monitor the water level in water tank 1-3 and water tank 2-7 respectively. The central controller 11 is electrically connected to the first water inlet pipe solenoid valve 1, the first remote liquid level gauge 2, the first water outlet pipe solenoid valve 4, the second water inlet pipe solenoid valve 5, the second remote liquid level gauge 6, the second water outlet pipe solenoid valve 8, the water tank connecting pipe solenoid valve 9 and the variable frequency water supply device 10, so as to control them.

[0030] Working principle: When it is necessary to clean water tank 1-3, the central controller 11 will first send a control signal to accurately close the first water inlet pipe solenoid valve 1, the second water outlet pipe solenoid valve 8 and the water tank connecting pipe solenoid valve 9. Subsequently, the variable frequency water supply device 10 will, according to the preset operation process, only draw water from water tank 1-3 and supply it to users. At the same time, in order to monitor the water volume in water tank 1-3 in real time, the first remote liquid level gauge 2 will continuously measure. Once the first remote liquid level gauge 2 detects that the water level in water tank 1-3 reaches the preset low water level threshold, it will immediately send a low water level alarm signal. After receiving this signal, the central controller 11 will quickly respond and send a new control signal to close the first water outlet pipe solenoid valve 4 connected to water tank 1-3 and simultaneously open the second water outlet pipe solenoid valve 8. In this way, the variable frequency water supply device 10 can seamlessly switch to water tank 2-7, draw water from water tank 2-7 and continue to supply water to users. At this time, only a small amount of water remains in water tank 1-3, and this amount of water is sufficient for cleaning work. In this way, we can greatly reduce the drained water volume during water tank cleaning, thus effectively saving water resources and reducing water waste.
