Irrigation device utilizing energy of water flow in river

Abstract

The invention discloses an irrigation device utilizing energy of water flow in a river. A pump shaft of a vane pump in the device is connected with a gearbox output shaft of a step-up gearbox, a gearbox input shaft of the step-up gearbox is connected with one end of a first transmission shaft, the other end of the first transmission shaft is connected with a second transmission shaft, and the second transmission shaft is connected with a propeller. The first transmission shaft and the second transmission shaft are connected through a bevel gear reversing apparatus, water pipes comprise a water pumping pipe and a water outlet pipe, the water inlet end of the vane pump is connected with the water pumping pipe, and the water outlet end of the vane pump is connected with the water outlet pipe. The device is mainly installed in the river with moderate water flow velocity and small span on both sides, is driven only by hydraulic power, does not need to be driven by electric power or other energy sources, is suitable for areas where the river passes and no electric power is input, and can be used for wasteland greening and agricultural development engineering; and the conveyed water flow is continuous, when the water pumping amount is small, the device can be combined with a drip irrigation technology, and therefore the function of continuous water supply all year round is achieved.

Description

technical field [0001] The invention relates to an irrigation device, in particular to an irrigation device which does not need to be driven by electric power, in particular to an irrigation device utilizing the energy of water flow in a river. Background technique [0002] The kinetic energy of water refers to the kinetic energy in the horizontal direction of river water, which has the following characteristics. Compared with other water conservancy irrigation and power generation equipment, it has the following advantages: [0003] This new type of energy has the characteristics of green and non-polluting energy, and can generate, transmit and apply continuous output energy. [0004] Rivers are dominated by rainwater, and rainwater can be forecasted, so hydrodynamic power generation can also be prevented to avoid unnecessary losses. [0005] Compared with building a dam to generate electricity, a non-dam hydropower station does not require a high dam, does not change the...
