Large-sized water bag device for collecting rainwater

Abstract

The invention discloses a large-sized water bag device for collecting rainwater. The device comprises a floating ball layer, a sunshade thin film layer and a waterproof thin film layer; the waterproofthin film layer is laid under water; the sunshade thin film layer covers the upper portion of the water; the floating ball layer is attached under the sunshade thin film layer and comprises a plurality of floating balls, and water leakage holes are formed in the portions, among the floating balls, of the sunshade thin film layer. The device has the advantages that the structure is simple, the construction cost is low, a lot of operation of digging and hardening on the ground is not needed, a large amount of cement steel is not needed, and large equipment does not need to enter a factory. Theshape of a reservoir (a water bag) can be designed by fully utilizing topographical features, the diversity is high, the requirements for terrains are low, the reservoir can be constructed beside mountains according to the terrain, and the shape is diverse. The water evaporation loss is low, and an important significance is provided for keeping the water level under high-temperature weather. The reservoir is closed and opaque, debris is prevented from falling into the reservoir, algae breeding is inhibited, the danger that people and animals fall into the reservoir is reduced, and the purposeof periodic removal of sediments is achieved. The service life of the product is prolonged through light reflection of aluminum foil.

Description

technical field [0001] The invention relates to a large water bag device for collecting rain. Background technique [0002] The cistern is a long-term device used for agricultural irrigation, domestic water, and industrial water storage. The upper cover can be set according to the water quality requirements, and the waterproof soil and waterproof membrane can be made at the bottom according to the needs of the project. In areas with landform features such as mountains, karst, rocky desertification, northwest desertification, and Gobi Desert, transportation is difficult, soil water demand is low, and water cannot be maintained, so the construction of pools is very important. Disadvantages of traditional cement storage tanks: the ground needs to be excavated and hardened; cement, steel and other materials need to be transported, which is extremely inconvenient in mountainous areas; there is a risk of people falling; open pools need to regularly clean up sediment at the bottom,...

Problems solved by technology

Disadvantages of traditional cement storage tanks: the ground needs to be excavated and hardened; materials such as cement and steel need to be transported, which is extremely inconvenient in mountainous areas; there is a risk of people falling in storage; open pools need to regularly clean up sediment at the bottom, and the evaporation is large; In order to suppress the evaporation of lake water, a foreign team placed a large number of plastic balls on the entire lake surface. The plastic balls completely covered the lake surface and played a role in inhibiting evaporation.

However, the plastic balls cover the pool, which is costly; there are gaps between the floating balls, and the color is black (the foreign team chose black glossy light in consideration of inhibiting the growth of algae in the pool), and the evaporation is large; the pool is not closed, and there are people falling, The problem of falling debris such as dead leaves
