Description

a water saving device

technical field

The utility model belongs to the field of energy-saving and water-saving equipment, in particular to a water-saving device.

Background technique

Water plays an important role in our life. It is the source of life and one of the most important material resources that human beings rely on for survival and development. Human life cannot be separated from water for a moment, and water is the most important material that human life needs. Our waste of water resources is very serious. The phenomenon of "wasting hands and feet" in domestic water can be seen everywhere. Someone has calculated that if the faucet is not turned off tightly, and only a stream as thin as a matchstick flows out, 432 liters of water will be wasted in one day and night. If you do not turn off the faucet when you shower and soap, take a bath It takes 60 liters of water to waste. When washing vegetables, you don’t need to wash them with water in the basin, but turn on the tap to wash them, and you will waste 100 liters of water for a meal. As for the waste of production water, it is even more alarming. Most of the agricultural irrigation in our country still uses " Half of the irrigation water leaked during the water delivery process, and the utilization rate was only about 40%, which was less than half the level of developed countries. Industrial water technology was backward, resulting in industrial The water consumption per 10,000 yuan of output value is as high as 103 cubic meters, while that of the United States is 8 cubic meters, and that of Japan is only 6 cubic meters. The industrial water reuse rate is 75-85% on average in developed countries, while it is only about 55% in China. Therefore It can be seen that saving water is a matter of great significance that everyone should pay attention to, everyone has a responsibility, and everyone can do their best.

In daily life, when using water, people open and close the water valve by hand, but sometimes they forget to turn off the tap when they are busy washing things, causing the water to flow away for a long time in vain, resulting in a great waste of water resources.

Contents of the invention

The purpose of this utility model is to provide a water-saving device, which overcomes the shortcomings of the prior art, has a simple structure, a reasonable design, is convenient to use, and can automatically close the faucet, saving water and avoiding a large amount of waste of water resources.

The technical solution of the utility model water-saving device: a water-saving device, including a water tank, characterized in that: the water-saving device also includes a faucet, a PLC control module, a stepping motor and a water level detection sensor;

The faucet is set above the water tank, a water level detection sensor is provided on the upper left side of the inner wall of the water tank, a stepping motor connected to the faucet switch valve is provided on one side of the water faucet, and a PLC is provided on one side of the stepping motor control module; the PLC control module is connected with the stepping motor and the water level detection sensor respectively, when the water level in the tank reaches the critical water level height of setting, the water level detection sensor can produce a signal to the PLC control module, and the PLC control module controls the step The input motor rotates, and the faucet switch valve is closed by the stepping motor rotation; when the water level detection sensor does not detect the critical water level, the water level detection sensor has no signal output, the faucet switch valve is in the open state, and the whole system is in standby state.

In the above technical solution, a water level detection sensor module is set at a certain height in the water tank. When the water in the water tank reaches a certain water level height, the water level detection module will generate a signal to the PLC control module, and the stepping motor and the switch of the faucet will be in phase. Connected and controlled by PLC, the stepper motor rotates and the faucet is automatically turned off. When the critical water level is not detected, the whole system is in a standby state. The utility model can well play the role of saving water, has a simple structure, is convenient to realize functions, is low in price, and avoids a large amount of waste of water resources.

Detailed ways

The technical solutions in the embodiments of the utility model are clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.

As can be seen from FIGS. 1 to 2 , a water-saving device includes a sink 1 , a faucet 2 , a PLC control module 3 , a stepping motor 4 and a water level detection sensor 5 . The faucet 2 of the present embodiment is arranged above the water tank 1, and a water level detection sensor 5 is arranged on the upper left side of the inner wall of the water tank 1, and a stepping motor 4 connected with a water faucet switch valve is provided on one side of the water faucet 2. One side is provided with a PLC control module 3 . In this embodiment, the PLC control module 3 is connected with the stepper motor 4 and the water level detection sensor 5 respectively, and when the water level in the tank 1 reaches the set critical water level height, the water level detection sensor 5 will generate a signal to the PLC control module 3 , the PLC control module 3 controls the stepper motor 4 to rotate, and the tap switch valve is closed by the stepper motor 4; when the water level detection sensor 5 does not detect the critical water level, the water level detection sensor 5 has no signal output, and the faucet switch valve is in an open state , the whole system is in standby state.

In this embodiment, a water level detection sensor 5 is set at the upper left side of the water tank 1.
