New energy farm irrigation device

Abstract

The invention discloses a new energy farm irrigation device, which adopts solar energy as new energy for energy supply, is clean and environment-friendly, and does not need to build a long-distance power supply circuit. A disc type solar heat collecting device and a heat collector are arranged, solar energy is converted into heat energy, a heat accumulator heats water into steam to push a steam turbine to rotate, and the steam turbine drives a water pump to irrigate farmland through a coupler. The device does not need to be provided with a cooling water source, irrigation water enters the condenser to cool steam, the temperature of the irrigation water is increased to the water temperature required by crops, and the self-cooling and irrigation water temperature adjusting functions are achieved. In sunny days, farmland drought needs irrigation, the device converts solar energy to drive a water pump to irrigate, irrigation is not needed in rainy days, the device does not convert solar energy any more, and irrigation cycle self-adaptive adjustment is conducted according to weather. A telescopic water diversion corrugated pipe is arranged, a plurality of adjusting valves are arranged along the line, the water outlet positions of the adjusting valves can be set through stretching, the precise irrigation function is achieved, the opening degree of the adjusting valves is adjusted according to the drought condition of the land to control the water outlet amount, and the problem of uneven irrigation is solved.

Description

technical field [0001] The invention belongs to the technical field of farmland irrigation, in particular to a new energy farmland irrigation device. Background technique [0002] Farmland is generally located in the wild far away from residential areas, and traditional hydraulic irrigation methods require the construction of long-distance power supply lines. Several utility poles are set along the power supply line, which not only occupies land, but also complicates maintenance in the later stage. At the same time, the long-distance wires are too long, and the current consumption on the wires is large, resulting in waste of electric energy, and it is inconvenient to pull the wires at a long distance, and external environmental uncertainties affect the safety of long-distance power supply. Part of the irrigation is powered by small diesel combustion power generation devices, which will produce a large amount of high-temperature exhaust gas and smoke. The combustion products...

AI Technical Summary

Problems solved by technology

The device does not need to be equipped with a cooling water source, the irrigation water enters the condenser to cool the steam to realize the self-cooling function, and the irrigation water is heated by the steam to reach the water temperature required by the crops, which solves the problem of too low irrigation water temperature, realizes the irrigation water temperature adjustment function, and effectively utilizes the steam heat. High energy efficiency
