Problems solved by technology

However, building reservoirs on islands or on land is not only expensive, but also takes up valuable cultivated land or cannot find a suitable site (for terrain or geological reasons), and there are certain difficulties in the preservation of fresh water resources.

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, according to the principle that the specific gravity of seawater is greater than that of freshwater and the difference in buoyancy produced by seawater and freshwater of the same volume, the soft floating body reservoir 1 made of impermeable tough material is floated on the sea surface, and a water collecting reservoir is provided on land in addition. Ditch 2, a supporting pocket tent 3, and a water pump 4 are respectively connected to the floating body reservoir 1 with a water diversion pipe 5.

[0016] Such as figure 2 , 3 , 4, wherein the soft floating body reservoir is a bag-like structure consisting of a top cover 11, a water storage bag 12, and a semi-automatic sewage discharge mechanism 13, and the upper end of the water storage bag 12 is fixed on the edge of the top cover 11. The lower end is provided with a semi-...

Abstract

According to the principle of that specific weight of seawater is greater than that of fresh water and buoyance difference produced between seawater and fresh water in equal volume, the said invention adopts a flexible float water storage reservoir which is made of watertight flexible material and floated at sea, and a water-collecting channel, a support bag-shaped tent and a water pump are set up on the land, and are respectively connected with the described water storage reservoir by means of water pipes, among which the described flexible float water storage reservoir is a bag-shaped structure consisting of top cover, water storage bag and semi-automatic blowdown mechanism, the upper end of said water storage bag is fixed on the periphery of top cover, and its lower end is equipped with semi-automatic plowdown mechanism. It is low in cost, and can collect and store fresh water.

Description

technical field [0001] The invention relates to water conservancy projects, in particular to a method for storing fresh water on sea islands where fresh water is scarce. Background technique [0002] Fresh water is an indispensable resource for social maintenance and development. Many islands have become uninhabited desert islands due to severe water shortages. It is very difficult for officers and soldiers stationed on the islands to use water, and it costs a lot of money to transport fresh water by boat. In the rainy season, a large amount of fresh water flows into the sea due to the lack of reservoirs, which greatly wastes fresh water resources. In view of the shortage of fresh water resources, natural precipitation is stored for living and planting water, so as to solve the problem of fresh water supply in islands and strengthen national defense and development and utilization of oceans. Homeland is important. However, building reservoirs on islands or land is not only ...
