A device for automatic irrigation with ditch artesian water according to the depth of farmland water level

Abstract

The invention provides a device for achieving automatic irrigation by using ditch artesian water according to the depth of a farmland water level. The device comprises a detection mechanism, a water retaining mechanism and a water level detection probe; the detection mechanism is composed of a first stabilization rod, a rain-proof cover, a first power supply, a first power supply switch, a first detection circuit, a second detection circuit, a first control circuit, a second control circuit and a wireless transmitting unit, wherein the rain-proof cover and the first stabilization rod are installed on the upper portion and the lower portion of a plastic element box, and the other elements are connected with the interior of the plastic element box through wires and installed in the plastic element box. The water level detection probe is composed of a plastic base plate, a second stabilization rod and a copper rod, wherein the stabilization rod and the copper rod are installed on the lower portion of the plastic base plate. The water retaining mechanism is composed of a second power supply, a second power supply switch, a voltage stabilizing circuit, an element box, a wireless receiving unit, a first driving circuit, a second driving circuit, a microswitch, a gate facility and a motor deceleration facility, wherein the element box is installed on the right side of the motor deceleration facility, the element box and the microswitch are installed on the gate facility, and the other elements are connected with the interior of the element box through wires and installed in the element box. By means of the device, farmland can be automatically irrigated by using the ditch artesian water.

Description

technical field [0001] The invention relates to the field of agricultural irrigation devices, especially without manual operation, can achieve fully automatic control, uses dry batteries and accumulators as power sources, does not need an external AC power supply, and is used when the water level in farmland (such as rice fields or fish ponds) is lower than At the lowest setting position, the water level in the ditch can be raised through the relevant mechanism and flow into the farmland to prevent the crops planted in the farmland or the fish being farmed from lack of water, resulting in reduced production or even death. When the amount of water flowing into the farmland reaches the highest setting When the water level is high, the water level in the ditch can be lowered through relevant agencies to prevent too much water in the ditch from flowing into the farmland, causing waste of water, affecting crop growth, or escaping fish in the pond.

Problems solved by technology

[0003] In order to overcome the existing farmland (such as rice fields or fish ponds), when water in ditches is used as irrigation water source, managers need to inspect the farmland frequently, and manual operation is required when the water level of the farmland is lowered, which brings great inconvenience to the usual farmland management. , when the farmland lacks water and the management personnel do not find it in time, it will cause the crops planted in the farmland to decrease or the fish to die. Disadvantages of waste, affecting the growth of crops or the escape of fish cultured in ponds, the present invention provides automatic control without manual operation, uses dry batteries and accumulators as power sources, does not require external AC power sources, and can be used as farmland (such as When the water level in the paddy field or fish pond) is lower than the minimum set position, the water level in the ditch can be raised and flowed into the farmland through the relevant mechanism, so as to prevent the crops planted in the farmland or the fish being raised from lack of water to cause production reduction or even death. When the amount of water flowing into the farmland reaches the maximum set water level, the water level in the ditch can be lowered through the relevant mechanism to prevent too much water in the ditch from flowing into the farmland, causing waste of water, affecting the growth of crops or escaping the fish raised in the pond A device for automatic irrigation with ditch artesian water according to the depth of farmland water level
