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] This invention relates to an automated water conveyance and irrigation control device, and more particularly to a water conveyance and irrigation control device that can be controlled instantly and easily. Background Technology

[0002] The automated irrigation control device I invented is particularly suitable for large-scale irrigation, but if the same structure is used for small-area irrigation over short distances, it will be bulky, too costly, and too cumbersome to control. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides an automated water conveyance and irrigation control device, which is not only suitable for short-distance, small-area irrigation, but also greatly simplifies the control of large-scale water conveyance and irrigation, reduces pipeline pressure, and makes the equipment lightweight and miniaturized.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: A contact switch ksupply is installed below the buoyancy control switch at the water supply end, and the pipeline is connected to the contact blade, return spring, and base. A contact switch kreceive is installed below the buoyancy control switch at the water receiving end, and the pipeline is connected to the contact blade, return spring, and base. The ksupply, kreceive, water pump control switch, and power supply are connected in series with wires. When water is available at the water supply end, water enters the buoyancy control switch, the pipeline pulls the ksupply contact blade and overcomes the tension of the connected return spring to close the connection with the wire. When there is no water at the water receiving end, water flows out of the buoyancy control switch, the pipeline loses tension, and the kreceive contact blade closes with the wire under the tension of the return spring. Thus, the entire wire completes a loop closure, the circuit current is connected, and the water pump control switch is activated to supply water. If there is no water at the water supply end or water at the water receiving end, the water pump control switch cannot be activated.

[0005] The beneficial effects of this invention are that it is suitable for irrigation of small areas at close range and can also greatly simplify the control of large-scale irrigation, reduce pipeline pressure, eliminate the need for large buoyancy control switches, and make the equipment less bulky and smaller.

[0009] In the figure, a contact switch k_supply (3) is installed below the buoyancy control switch (1) at the water supply end. The pipeline (13) is connected to the contact blade (11), the return spring (5), and the base (7). A contact switch k_receive (4) is installed below the buoyancy control switch (2) at the water receiving end. The pipeline (13) is connected to the contact blade (12), the return spring (6), and the base (8). The k_supply (3), k_receive (4), the water supply pump control switch (10), and the power supply (9) are connected in series with a wire (14). When water is available at the supply end, water enters the buoyancy control switch (1), and the pipeline (13) pulls the contact knife (11) of the supply (3) and overcomes the tension of the connected return spring (5) to close the conductor (14). When there is no water at the receiving end, water flows out of the buoyancy control switch (2). The pipeline (13) loses tension, and the contact knife (12) of the receiving (4) closes with the conductor (14) under the tension of the return spring (6). In this way, the entire conductor (14) completes a loop closure, the circuit current is connected, and the water supply pump control switch (10) is turned on to supply water. If there is no water at the supply end or water at the receiving end, the water pump control switch (10) cannot be turned on.

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.
