Automatic water delivery irrigation control device

Abstract

According to the automatic water delivery irrigation control device, only when water exists at a water supply end and no water exists at a water receiving end, a wire can be closed by a contact switch and a contact knife, so that a water pump control switch connected in series in a circuit is started.

Description

TECHNICAL FIELD

[0001] The utility model relates to an automatic water conveying irrigation control device, especially a water conveying irrigation control device which can be instantaneously and simply controlled. BACKGROUND

[0002] The automatic irrigation control device of the utility model is particularly suitable for large-scale irrigation, but for short-distance and small-area irrigation, the same structure is bulky, high in cost and difficult to control. SUMMARY

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides an automatic water conveying irrigation control device which can greatly simplify large-scale water conveying irrigation control, reduce pipeline pressure and realize equipment lightening and miniaturization in addition to being suitable for short-distance and small-area irrigation.

[0004] The utility model solves technical scheme that its technical matters are as follows: one contact switch k is equipped below the buoyancy control switch of water supply end, and pipeline line is connected with contactor, reset spring and base. One contact switch k is equipped below the buoyancy control switch of water receiving end, and pipeline line is connected with contactor, reset spring and base. K supply, k receiving, water supply pump control switch and power supply are connected in series with wire. When water is supplied in water supply end, water enters the buoyancy control switch, and pipeline line pulls k supply contactor and overcomes the pulling force of the reset spring connected with wire to be closed, when there is no water in water receiving end, water flows out in the buoyancy control switch, and pipeline line loses the pulling force, and k receiving contactor is closed with wire under the pulling force of reset spring, so that the whole wire completes annular closure, circuit current is connected, and water supply pump control switch is connected to water supply. When there is no water in water supply end or water in water receiving end, water pump control switch cannot be connected.

[0005] The utility model has the advantages of being suitable for short-distance and small-area irrigation, greatly simplifying large-scale irrigation control, reducing pipeline pressure, not needing large-scale buoyancy control switch, and realizing equipment omission, lightening and miniaturization.

[0009] In Figure 1 a contact switch k supply (3) is arranged below the float control switch (1) at the supply end, the pipeline wire (13) is connected with the contactor (11), the reset spring (5) and the base (7), a contact switch k receiving (4) is arranged below the float control switch (2) at the receiving end, the pipeline wire (13) is connected with the contactor (12), the reset spring (6) and the base (8). The k supply (3), k receiving (4), the water supply pump control switch (10) and the power supply (9) are connected in series by the wire (14). When there is water at the supply end, the water enters the float control switch (1), the pipeline wire (13) pulls the contactor (11) of k supply (3) and overcomes the pulling force of the connected reset spring (5) to close the wire (14), when there is no water at the receiving end, the water in the float control switch (2) flows out, the pipeline wire (13) loses the pulling force, the contactor (12) of k receiving (4) is closed with the wire (14) under the pulling force of the reset spring (6), so that the whole wire (14) completes the loop closure, the circuit current is connected, the water supply pump control switch (10) is connected to supply water. If there is no water at the supply end or there is water at the receiving end, the water pump control switch (10) cannot be connected.

Claims

1. An automated water conveyance and irrigation control device, characterized in that: A closed loop circuit consists of a power supply, a water pump control switch, a water supply end contact switch, and a water receiving end contact switch connected in series. The contact blade of the water supply end contact switch is connected to the buoyancy control switch, return spring, and base at the water supply end via a conduit. The contact blade of the water receiving end contact switch is also connected to the buoyancy control switch, return spring, and base at the water receiving end via a conduit. Only when there is water at the water supply end and no water at the water receiving end, both the water supply end contact switch and the water receiving end contact switch are closed with the conductor, thus achieving a closed loop circuit, energizing the water pump control switch.
