RU2638312C1 - Sprinkling machine for mountain and foothill terrain areas - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: sprinkling machine for mountain and foothill terrain areas comprises a water supply pipeline with sprinkling devices. The pipeline is placed on trolleys with electric drives. The control, movement and navigation of the sprinkling machine is carried out due to electrical energy generated by a micro-HPP. The energy is generated by using the head of water in the supply pipeline. The head in the pipeline is supported by a difference in the terrain between the water source and the irrigated area.

EFFECT: excluding the need for external power supply, the use of fuels and lubricants, the depreciation of machines and mechanisms.

Description

The invention relates to agriculture, namely to irrigation equipment, and can be used on irrigated lands using multi-support (wide-grip) front and circular irrigation machines for mountain and foothill areas with water intake from a closed irrigation network.

Known multi-support sprinkler machine type DKSh-64 "Volzhanka", DKG-80 "Oka" (Land reclamation and water management. Irrigation: a reference book / Edited by B. B. Shumakov. - M .: Kolos, 1999. - P. 100- 107). Watering is carried out positionally along the hydrant line, and the movement of the machine from the hydrant to the hydrant is mechanized from the internal combustion engine.

The disadvantage of these machines is that the movement is carried out using an internal combustion engine, and this is associated with the cost of gasoline and fuels and lubricants.

Known multi-support sprinkler machine DF-120 "Dnepr" with a drive from a mobile power plant DP-11.000 with a drive from a tractor (Land reclamation and water management. Irrigation: a reference book / Edited by B. B. Shumakov. - M .: Kolos, 1999. - p. 107-110).

The disadvantage of this machine is that the movement is carried out using electric motors mounted on carts that receive electricity from a generator mounted on a tractor and moving with the sprinkler. As in the previous case, the costs of fuels and lubricants, as well as the depreciation of the tractor are necessary.

Known electrified low-pressure irrigation machine MDEK "Kuban-LK-1", designed for irrigation in movement in a circle of crops. Electricity to the machine for movement and control is supplied from the transformer substation through the collector ring mounted on the rotary elbow of the machine to the fixed support (Land Reclamation and Water Management. Irrigation: Handbook / Ed. By B. B. Shumakov. - M .: Kolos, 1999. - p. 119-127).

The disadvantage of this machine is the need for a source of electricity from an external electrical network, for which you must pay.

As a prototype of the invention, a Bauer front-movement sprinkler was selected, which includes a water supply pipeline with rain-forming devices placed on carts with electric drives powered by an external electric network or an internal electric generator with an internal combustion engine. All electrical equipment of the machine, including navigation systems, is fed from the same sources of energy (see the catalog of the Waieg company Irrigation Technique Rochren-und Pum-penwerk Bauer Ces.m.B.H. A-8570 Voitsberg (Austria)).

The disadvantage of these machines is the need for a sufficiently powerful, about 15 kW, source of electricity received from an external electric network for which you must pay, or an internal electric generator with an internal combustion engine with the cost of fuels and lubricants.

The aim of the invention is to develop a source of electricity for powering the electrical equipment of the sprinkler machine frontal and circular movement.

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 installing a micro-hydroelectric power station on the sprinkler machine, which is connected in series with the sprinkler machine pipeline and generates a voltage of 380 V, necessary for powering the equipment and moving the sprinkler. The functional operation of the sprinkler machine with the micro-hydroelectric power station is carried out due to natural changes in the terrain, at least 70 m, between the water source (channel, river) and the irrigated area, where sprinkling machines of circular or frontal action are installed. As an example, individual sections of water supply canals (BSK-3, BSK-4) or rivers of mountainous and foothill areas can be used.

The invention is illustrated by drawings.

 In FIG. 1 shows a layout diagram of a sprinkler of circular action with a micro-hydroelectric station; in FIG. 2 is a diagram of an installed micro-hydroelectric station on a front sprinkler.

The numbers in the drawings indicate:

1 - inlet pressure pipe;

2 - micro-hydroelectric power station;

3 - sprinkler machine.

The generation of electric energy at micro-hydroelectric power station 2 is carried out due to the acting pressure in the supply pipe 1, part of which is used to generate electric energy of micro-hydroelectric station 2, the other part is used for irrigation machine 3. The generated electric energy at micro-hydroelectric station 2 is used for power supply of the electric equipment of the sprinkler 3, including navigation.

Claims (1)

A sprinkler machine for mountainous and foothill sections of the terrain, which includes a water supply pipeline with rain-forming devices, placed on carts with electric drives, characterized in that the control, movement and navigation of the sprinkler are carried out due to the electric energy generated by the micro-hydroelectric station installed directly on the sprinkler to the machine during frontal movement or outside it during circular movement, by using part of the acting internal pressure of water in the supply a pipeline, which is created due to the natural difference in terrain between the water source and the irrigated area.
