Rainwater collection system based on PVC large-calibre pipe

Abstract

The invention relates to a rainwater collection system based on a PVC large-calibre pipe. The rainwater collection system comprises a liquid storage mechanism and a liquidometer, wherein the liquid storage mechanism and the liquidometer are connected by a catch basin arranged under the ground. The liquidomter is used for detecting the height of a water level in a catch basin; and a plurality of timing spraying devices are arranged at a green belt region on the ground. The liquid storage mechanism mainly includes a liquid storage container main body and a water suction pump; the liquid storage container main body is formed by connection of plastic-steel winding pipes; an inlet is connected with a catch basin by a water conveying pipe and a valve is installed on the water conveying pipe; and an outlet is connected with the timing spraying devices at the ground green belt region by the water suction pipe and the water conveying pipe. The liquidometer is installed in the liquid storage container main body and is used for detecting the height of the water level of the main body; and a venturi pipe is arranged at the bottom inside the main body. The system has the following advantages: water from rainstorm that can not be treated by the drainage system in the city can be collected automatically and used; and with the liquid storage container main body, formed by connection of the plastic-steel winding pipes, the corrosion-resistant and the pressure-resistant performances of the liquid storage container main body can be enhanced.

Description

technical field [0001] The invention relates to the field of rainwater collection and utilization, in particular to a rainwater collection system based on PVC large-diameter pipes. Background technique [0002] Rainwater harvesting has been used in developed countries for decades. In recent years, my country's urbanization has been rapid, and roads have been cemented rapidly. On rainy days, rainwater can no longer penetrate into the ground. The drainage system in cities is difficult to cope with heavy rain. More and more rainwater is not only wasted in vain, but also causes low-lying roads to be excessive. The stagnant water has formed a disaster that hinders traffic. Urban construction requires a lot of water resources, such as household water, urban greening and other places need a lot of water, rainwater collection and utilization is one of the important measures for the sustainable use of urban water resources. [0003] At present, urban rainwater collection and utiliza...

AI Technical Summary

Problems solved by technology

[0003] At present, urban rainwater collection and utilization are difficult to cope with heavy rains. When the original drainage system in the city cannot discharge rainwater in time, it is not conducive to rainwater drainage and utilization, which will cause excessive water accumulation on the road surface, affecting traffic, and the rainwater that cannot be discharged will be wasted in vain. ; The traditional rainwater collection container below the ground has poor pressure resistance and corrosion resistance. After a long time of use, it will cause aging and damage to the rainwater collection container

[0004] In summary, the rainwater collection and utilization in the prior art has the following defects: it cannot collect and utilize the torrential rain that is difficult for the drainage system in the city, and the rainwater collection container has poor pressure resistance and corrosion resistance

PVC-U pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of PVC-U monomer and additives, it is only suitable for water supply systems whose delivery temperature does not exceed 45°C.
