Point type reservoir

Abstract

The invention provides a point type reservoir which can be constructed at any raining place on the land, can automatically store rainfall and avoid evaporation, infiltration and pollution, is used as a water source in draught and water shortage, can store the rainfall during continuous raining or storm, reduce sand which is scoured from the ground and enters the reservoir and reduce probability of debris flow, landslide and flood, and can rationally distribute the rainfall and reduce disasters such as draught. The point type reservoir comprises a water storage tree and an underground water storage system, wherein the water storage tree comprises a trunk and a crown; the trunk is a closed hollow column body; the crown comprises a water collector for collecting rainwater and making the rainwater flow into the trunk; the water collector comprises blades and blade handles; the blades are curved surfaces with middle sunken parts and two high sides; the upper end of each blade handle with a through hole is connected to the edge of the sunken part of each blade; the lower end of each blade handle passes through a blade handle hole in a trunk wall and extends into an inner cavity of the trunk; and the underground water storage system comprises an anti-seepage pipeline which is arranged in the ground and is communicated with a water outlet in the lower part of the trunk.

Description

technical field [0001] The technology relates to a reservoir, specifically a point reservoir, and belongs to the technical field of water resources utilization and protection. Background technique [0002] Up to now, the Intergovernmental Panel on Climate Change (IPCC) of the United Nations has completed four assessment reports on the Earth's climate change in 1990, 1996, 2001 and 2007. The Fourth Assessment Report concludes: climate change is unambiguous! Human activities are likely to be the main cause of climate warming, with a probability of more than 90%. The hazards of global climate change: First, it will directly lead to serious problems such as changes in global and regional precipitation intensity and distribution, retreat of glaciers, rise in sea levels, submersion of many islands, destruction of biodiversity, intensification of species changes, and loss of a large number of species. Second, the frequency and intensity of high temperature and heat waves may incr...

AI Technical Summary

Problems solved by technology

Second, the frequency and intensity of high temperature and heat waves may increase, and extreme weather and climate events and meteorological disasters caused by high temperature, dry heat, etc. may occur frequently, affecting the environment and resources on which human beings depend, causing the deterioration of the living environment, water shortages, and seriously affecting agriculture and forestry. industry and fish production

The existing coping technologies are mainly to build a large number of reservoirs and supporting irrigation systems through water conservancy projects, but these facilities have great limitations: First, because these facilities are located in areas where rivers flow, the stored water is in the form of surface runoff. The accumulation of sediment in the reservoir is very fast, the water pollution is serious, and the cost of dredging and water pollution treatment is very high; the second is that the infiltration of water is very large, which reduces the utilization rate of stored water; the third is that the reservoir In the case of long-term drought, water storage is often exhausted due to water surface evaporation and infiltration, and its original function is lost. Fourth, the construction of reservoirs and supporting irrigation systems is limited by geographical conditions, and most of them are built in areas where rivers flow. It is not possible to build anywhere where water is needed; fifth, the investment and cost of building reservoirs and supporting irrigation systems are large
