CN-122004107-A - Automatic change water delivery irrigation controlling means

Abstract

An automatic water delivery irrigation control device can close a wire by touching a contact switch only when water exists at a water supply end and no water exists at a water receiving end, so that a water pump control switch connected in series in a circuit is started.

1. 1. An automatic water delivery irrigation control device is characterized in that a power supply, a water pump control switch, a water supply end contact switch and a water receiving end contact switch are connected in series in a ring-shaped closed circuit, a pipeline for a contact knife on the water supply end contact switch is connected with a buoyancy control switch, a reset spring and a base of a water supply end, the pipeline for the contact knife on the water receiving end contact switch is connected with the buoyancy control switch, the reset spring and the base of a water receiving end, and the water pump control switch can be realized only if the water supply end has water and the water receiving end is not water, and the water supply end contact switch and the water receiving end contact switch are all closed with wires, so that the ring-shaped closing of the circuit can be realized to switch on the current to switch on the water pump control switch.

Description

Automatic change water delivery irrigation controlling means Technical Field The invention relates to an automatic water delivery irrigation control device, in particular to a water delivery irrigation control device capable of being controlled instantaneously and simply. Background The automatic irrigation control device invented by the inventor is particularly suitable for large-scale irrigation, but is large in structure, too high in cost and too bulky to control for short-distance small-area irrigation if the same structure is used. Disclosure of Invention In order to overcome the defects, the invention provides an automatic water delivery irrigation control device which is suitable for short-distance small-area irrigation, can greatly simplify large-scale water delivery irrigation control, lighten pipeline pressure and lighten and miniaturize equipment. The invention solves the technical problems by adopting the technical scheme that a contact switch k is arranged below a buoyancy control switch at a water supply end for supplying water, and a pipeline is connected with a contact knife, a reset spring and a base. A contact switch k is arranged below the buoyancy control switch at the water receiving end, and a pipeline line is connected with the contact knife, the reset spring and the base. The control switch of the k-supply, k-receiving and water supply pump and the power supply are connected in series by leads. When water is supplied to the water supply end, water enters the buoyancy control switch, the pipeline pulls the k-shaped contact knife and overcomes the tension of the connected reset spring to be closed with the lead, when the water receiving end is free of water, the water in the buoyancy control switch flows out, the pipeline loses the tension, the k-shaped contact knife is closed with the lead under the action of the tension of the reset spring, and therefore the whole lead is closed in a ring shape, the circuit current is communicated, and the water supply pump control switch is communicated with water supply. If the water supply end is free of water or the water receiving end is free of water, the water pump control switch cannot be turned on. The invention has the advantages that the invention is suitable for short-distance small-area irrigation, can greatly simplify large-scale irrigation control, lighten pipeline pressure, does not need a large-scale buoyancy control switch, and omits equipment, is light and is miniaturized.
