RU197057U1 - A flexible container for storing fresh water in a mass of sea water, consisting of a supporting outer mesh plastic shell made of PVC film with a water supply system through a plastic pipe and its intake into the surface tank according to the airlift principle - Google Patents

Abstract

The proposed utility model is intended for storing fresh water in a flexible container installed in a mass of sea water, used for water supply and irrigation of settlements and agricultural enterprises in coastal areas. Fresh water can be taken from any sources (river, streams, rainfall) with a plastic feed the pipeline into flexible containers with a volume of 200-500 m3. The device of the container consists of a supporting outer plastic mesh and an inner shell of PVC film, attached with a polyester resin. A container with a built-in plastic pipe is hermetically sealed for supplying fresh water, into which a smaller diameter plastic pipe is integrated for air supply, which ensures fresh water intake according to the airlift principle. Using an adjustable switch in the pipe, fresh water from a flexible container is supplied to the surface tank after air supply to the pipe. 2 ill.

Description

Title:

A flexible container for storing fresh water in a mass of sea water, consisting of a supporting external mesh plastic shell made of PVC film with a water supply system through a plastic pipe and its intake into the surface tank according to the airlift principle.

Description:

The sources of fresh water available in coastal cities to the seas do not meet the needs of farms in the summer and autumn periods due to the lack of economical containers for storage.

Dams and dams for water intake from open sources, reservoirs for its storage are complex and expensive for construction and operation. Underground and surface tanks made of reinforced concrete, metal, plastic also do not solve the problem of economical storage of fresh water.

Considered as an analogue, the invention RU 2382150 C2 mentions a system for storing fresh water in flexible containers and examines in detail the arrangement of the inlet and outlet systems from ground tanks.

The technical problem, the solution of which is provided by this utility model, is the expansion of the arsenal of flexible containers for storing fresh water in the thickness of sea water.

The prior art:

Flexible containers consisting of a supporting mesh shell and an inner shell can be manufactured at any enterprise with air tightness testing. A plastic piping system with an integrated air supply pipe is mounted through an airtight cover after being launched.

The difference of the proposed utility model is:

- design of a flexible container with a volume of 200-500 m3;

- a system for supplying fresh water through a pipeline of plastic from a surface source;

- pressurized water intake system into the ground tank by airlift method (air supply through the inner pipe).

The technical result of the proposed utility model:

The device of economical frameless containers for storing fresh water in a mass of sea water, providing water supply to agricultural enterprises and municipal services in coastal regions, with a volume of 200-500 m3, in the required quantity.

The objective of the technical result when using:

Providing water supply to coastal agricultural enterprises and cities through the reservation of fresh water in flexible containers located in the bulk of sea water.

Utility Model Feature.

The proposed utility model of a flexible container installed in a mass of sea water consists of a supporting outer shell made of plastic mesh and an inner shell made of PVC film, attached with a polyester resin.

A hatch with a built-in plastic pipe is hermetically mounted in the upper part of the container - for supplying fresh water, into which a plastic pipe of a smaller diameter is integrated for supplying air, which ensures the intake of fresh water according to the airlift principle.

Fresh water is collected from seasonal rivers (streams) using an overflow dam, into which a plastic pipe is built, through which fresh water is supplied into a flexible container. The number of pipes corresponds to the number of flexible containers.

Using an adjustable switch in the pipe, fresh water from the flexible container is supplied to the surface tank after air is supplied to the pipe.

Utility Model Implementation

The use of the proposed utility model can be carried out in any coastal village and agricultural enterprise that has a source of seasonal water supply (rivers, streams, rainfall).
