Description

Floor water saving system

technical field

The utility model relates to a water-saving system, in particular to a floor water-saving system capable of collecting and utilizing a large amount of rainwater.

Background technique

Water cellar, a specific term produced in a specific area of China, refers to a tank-shaped (cylinder-shaped, bottle-shaped, etc.) container built underground to collect rainwater. In parts of the provinces and regions of the Loess Plateau in Northwest China, due to natural and historical reasons, there is an extreme shortage of water. Some rainfall is only about 300-400 mm, while the evaporation is as high as 1500-2000 mm. According to the statistics of available water resources, the per capita available water resources are only 110 cubic meters, which is 15.3% of the national available water resources of 720 cubic meters and 3.7% of the world's per capita available water resources of 2970 cubic meters. The water for people and livestock there is almost entirely dependent on artificially collected limited rainwater. The containers built underground to collect rainwater are called water cellars. Since there is not enough money to concrete harden the interior of such a cellar, leaks can occur very quickly. The harsh situation of severe water shortage has led to a difficult life for local farmers, primitive production, backward education, high rates of disease and neonatal mortality among women, and women bear the heavy burden of life that is several times that of women under normal circumstances.

Since 2001, the China Women's Development Foundation has started to implement the "Mother's Water Cellar" project. "Mother's Water Cellar" is a centralized water supply project. Gathering facilities such as yards and ditches can effectively store limited rainwater to provide basic drinking water for a year.

Detailed ways

With reference to Fig. 1 to Fig. 7, the utility model is implemented like this:

In Figures 1 to 6, each floor is equipped with a large-capacity water tank at the ceiling, and the large-capacity water tank collects the waste water from the previous floor except flushing toilets, and a fine-pore filter is installed at the entrance of the waste water. A clean filter is installed, and the water passing through the clean filter flows into the tank. When the water level is too high, it flows to the large-capacity water tank on the next floor through the overflow pipe. If the amount of waste water generated during washing and bathing is particularly large, then When the large-capacity water tank on the first floor is full, the excess water will flow to the underground water cellar through the overflow pipe, and be stored in the underground water cellar for clarification after cleaning the filter. The water pipe connected to the bottom of the large-capacity water tank is controlled by a water valve and a faucet. The water in the large-capacity water tank can be used for flushing the toilet and mopping the floor. When the water level of the large-capacity water tank is too low, the water level valve will automatically open and introduce a part The water is used as a backup, and in this embodiment, the water storage device is a rooftop water storage tank.

The rooftop reservoir is equipped with a high-standard filtration, cleaning and anti-virus device. The water produced after filtration, cleaning and anti-virus can be used for bathing and laundry, etc. Generally, tap water is only needed for cooking and drinking. There is a main water supply pipe at the bottom of the rooftop cistern to connect large-capacity water tanks on each floor, shower washing facilities, and ground washing and watering facilities. In addition, the rooftop cistern is also connected to a cooling tower to supply water to it. When the water level of the rooftop reservoir is too low, it will be supplied by the high-pressure water pump of the water cellar. When there is no water supply in the water cellar, the water level valve at the bottom of the rooftop reservoir will automatically open and be supplied by tap water.

Figure 7 is a schematic diagram of the automatic pumping control circuit of the present invention, the high-pressure water pump is automatically controlled by the first water level controller, the second water level controller, and the third water level controller, when the water level of the roof reservoir is lower than the second water level controller , the automatic pumping control circuit controls the water pump to work, and stops working when the water level rises to the third water level controller. If the water level of the underground water cellar is lower than the first water level controller, the high-pressure water pump does not work or stops working. There is a leakage protection switch. The utility model must regularly detect the water quality and replace the filter, clean and antivirus device in actual use.

The above is only a preferred embodiment of the floor water-saving system of the present utility model, and does not limit the technical scope of the present utility model. Changes and modifications all still belong to the technical scope of the utility model.
