Normal-pressure water supply anti-freezing device

Abstract

The invention discloses a normal-pressure water supply anti-freezing device. The normal-pressure water supply anti-freezing device is connected with a water tank of a water supply system, a water outlet pipeline of the water supply system penetrates through a ground frozen soil layer, the water tank is a normal-pressure water tank placed in an underground anti-freezing soil layer, a water outlet of the water tank is connected with a drainage pump, the drainage pump is a backflow-type drainage pump, and a drainage port of the drainage pump is connected with the water outlet pipeline. When the drainage pump is started, water in the water tank is pumped into the water outlet pipeline to be discharged; and when the drainage pump is stopped, remaining water in the frozen soil layer and areas above the frozen soil layer in the water outlet pipeline flows back into the water tank from the drainage pump. According to the normal-pressure water supply anti-freezing device, by controlling the start and stop of the backflow-type drainage pump, the remaining water in the water outlet pipeline is quickly discharged and then flows back into the water tank, the water source is saved, the problemsof icing and breaking of the water outlet pipeline penetrating through the frozen soil layer and located on the ground part are avoided, and the service life of the water outlet pipeline and the drainage pump is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of water supply, in particular to an antifreeze device for normal pressure water supply, which is suitable for users who need water in rural areas or outdoors in cold northern regions. Background technique [0002] With the popularization of tap water, tap water pipes have become an indispensable part. In rural areas, tap water pipes and faucets are generally installed in the yard. The outdoor temperature in winter is often below zero, especially in northern areas, where the temperature at night can be as low as minus ten degrees. For example, in the northeast of China, the coldest outdoor temperature in winter The temperature even reaches minus 30 degrees below zero, and the water in the water pipes will often freeze, causing people to be unable to use tap water or flush toilets normally, and even the water pipes will freeze and burst, causing farmers to suffer economic losses. [0003] At present, people ...

Problems solved by technology

In rural areas, tap water pipes and faucets are generally installed in the yard. The outdoor temperature in winter is often below zero, especially in northern areas, where the temperature at night can be as low as minus ten degrees. For example, in the northeast of China, the coldest outdoor temperature in winter The temperature even drops below minus 30 degrees, and the water in the water pipes will often freeze, causing people to be unable to use tap water or flush toilets normally, and even freeze and crack water pipes, causing farmers to suffer economic losses

[0003] At present, people often use heating methods to melt the ice in the water pipes. The whole heat preservation system is relatively complicated and the cost is high. This not only brings unnecessary troubles to people's lives, but also cannot fundamentally solve the problem of pipeline freezing
