Water supply/drainage system

Abstract

The invention discloses a water supply / drainage system, which comprises a plurality of water supply / drainage sub-systems and a monitoring center, wherein the water supply / drainage sub-systems comprise water tanks, electromagnetic valves, water pump modules and control modules; water inlets of the water tanks are connected to external water inlet pipes through pipelines by virtue of the electromagnetic valves, and water outlets of the water tanks are connected to the water pump modules through pipelines; liquid level sensors are arranged at the bottom of the water tanks; the water pump modules comprise water pumps and frequency converters; the water inlet ends of the water pumps are connected to the water outlets of the water tanks through pipelines, and the water outlet ends of the water pumps are connected to external water supply pipes through pipelines; pressure sensors are arranged at the water outlet ends of the water pumps; the frequency converters are used for regulating rotating speeds of the water pumps and are simultaneously used for acquiring real-time rotating speeds and currents of the water pumps; and the control modules are used for controlling the electromagnetic valves and the water pump modules to work, and are simultaneously used for transmitting received liquid level, water pressure as well as the real-time rotating speeds and currents of the water pumps to the monitoring center. The water supply / drainage system disclosed by the invention is simple in structure and convenient to use; and the water supply / drainage system is capable of guaranteeing and monitoring the working statuses of various water supply / drainage sub-systems in real time; therefore, the water supply / drainage system is relatively high in practical value.

Description

technical field [0001] The invention relates to the field of automatic detection and control, in particular to a water supply and drainage system. Background technique [0002] With the development of the city, there are more and more high-rise buildings, and the water supply of the buildings is becoming more and more important. [0003] Water tanks are generally used for water supply now, and the water filling of the water tanks is generally manually controlled. It is very inconvenient to manually observe the water level in the water tanks and frequently manually turn on or off the water filling switch. [0004] There are also float valves on the market to control the water tank for automatic water filling, but the float valve is used to control the automatic water filling of the water tank. On the one hand, because the float valve is based on a mechanical structure, it is prone to failure, which is not conducive to long-term use. For water injection, once the water surfac...

Problems solved by technology

[0003] Nowadays, water tanks are generally used for water supply, and the water filling of the water tanks is generally controlled manually. It is very inconvenient to manually observe the water level in the water tank and frequently turn on or off the water filling switch manually.

[0004] There are also float valves on the market to control the water tank for automatic water filling, but the float valve is used to control the automatic water filling of the water tank. On the one hand, because the float valve is based on a mechanical structure, it is prone to failure, which is not conducive to long-term use. Water injection, once the water surface is lower than the position of the float ball, the float valve will be opened to start water injection, the water at the bottom of the tank will not flow for a long time, which is easy to breed bacteria

[0005] Now that the buildings are getting taller and the heights of the buildings are inconsistent, so that when the water is supplied to the buildings on the ground, the water pressure required by each building is also different. At the same time, because the buildings are widely distributed, it is necessary to ensure that the water supply subsystem The water pressure is sufficient and can be monitored at any time, which cannot be achieved by the existing water supply and drainage system

[0006] The quality of the water in the water tank also needs to be guaranteed. The existing water tanks are generally filled with water from the water company, and the water quality is no longer monitored or further improved.
