Description

The invention relates to agriculture, namely to irrigation systems and can be used on irrigated lands using multi-support (wide-grip) front and circular irrigation machines for irrigation of crops with water intake from water channels, on which there are mating hydraulic structures in places of elevation terrain from 2 m or more.

A well-known irrigation system for irrigation of land, which includes a complex of interacting facilities pumping station, an external source of electric energy for irrigation of crops with electrified sprinklers of the type "Kuban-L", "Kuban-M", "Frigate", "Volzhanka", "Dnipro" (Land Reclamation: Textbooks and Textbooks. Manuals for University Students / Ed. By A.I. Golovanov. - M.: Kolos, 2011. - P. 147-155).

The disadvantage of this irrigation system is that the functional operation of the sprinkler machines and the pumping station is carried out from an external source of electrical energy through a transformer substation.

As a prototype of the invention, an irrigation system for irrigation of land was selected, which includes a complex of interacting structures pumping station, an external source of electric energy or an internal electric generator with an internal combustion engine, for irrigation of crops with electrified sprinklers of the Bauer type (see the catalog of the Bauer company »“ Irrigation equipment ”Rochren-und Pum-penwerk Bauer Ces.mBH A-8570 Voitsberg (Austria)).

The disadvantage of this irrigation system is that the work of the pumping station is carried out from an external source of electric energy, and the operation of sprinkler machines from an external electric network, which must be paid for, or of an internal electric generator with an internal combustion engine with the cost of fuels and lubricants.

The aim of the invention is the use of the potential energy of the water flow of the water supply channel by installing a small hydroelectric power station on the existing elevations of the terrain, which is necessary to provide electric power to the pumping station and electrical equipment for front and circular sprinklers.

The technical result that can be obtained by carrying out the invention is the exclusion of the cost of paying for an external electric network, the cost of fuels and lubricants, the depreciation of machines and mechanisms.

The technical result is achieved by the intra-system power supply of the irrigation system due to the use of the natural gradient of the terrain, creating an effective pressure of the water flow to generate electricity at a small hydroelectric station, which is located on a derivation pipeline located parallel to the adjoining structure, which will ensure the operation of the pumping station and the electrical equipment of irrigation systems of the irrigation system . Also, the generated electric energy can be supplied for operational and household needs.

The functional operation of the irrigation system with the installation of a small hydroelectric station is carried out due to natural changes in the terrain from 2 m or more on existing mating hydraulic structures (high-speed, differential) on the intrasystem water supply channel.

The invention is illustrated by a figure. The figure shows a diagram of the structures of a small hydroelectric station on the example of 111 km of the Tersko-Kumsky channel. The numbers in the figures indicate:

1 - existing rapid flow;

2 - inlet channel;

3 - wood;

4 - small hydroelectric power station;

5 - pumping station;

6 - irrigation system.

The operation of the irrigation system is as follows. The inlet part of the rapid flow 1 is blocked and the water from the inlet chambers of the supply channel 2 is supplied via a derivation pipeline 3 to a small hydroelectric station 4. The generated electric energy is supplied to a pump station 5 and to the operation of irrigation machines of the irrigation system 6 due to the acting pressure in the derivative pipeline of a small hydroelectric power station can be used for operational and household needs.
