Visual reel-type irrigator of water turbine and solar motor combined drive

Abstract

The invention discloses a visual reel-type irrigator of water turbine and solar motor combined drive. The irrigator is driven by using the traditional water turbine, and in order to overcome the problem that the water turbine cannot convey the silty water and reduce the head loss, a brushless direct current motor is combined to drive on the basis of the traditional water turbine; in the electric drive, the modern sensor technology is used, the normal running mode in the set speed can be achieved while the water source parameters are stable or the fluctuation is smaller, and the precision running mode in the set irrigation intensity can be achieved while the water source parameters are not stable or the fluctuation is larger; the manual adjustment is combined with the automatic adjustment for controlling, and a touch control screen is additionally installed, the man-machine operation interface is established, and the man-machine operation is achieved; and the irrigator has the advantages of energy conservation and environment protection, waster-saving and labor-saving, simple operation, high precision of irrigation, reliable performance, strong adaptability, real-time display of the running parameters and the like, and is used for the automation irrigation of the farm, pasture, crops and industrial crops under various complicated conditions.

Description

technical field [0001] The invention relates to the field of energy-saving irrigation, in particular to the improvement and innovation of the structure of the reel type sprinkler irrigation machine, which uses a visible water turbine and a solar motor to jointly drive the reel type sprinkler irrigation machine to perform sprinkling irrigation. Background technique [0002] As a kind of equipment for irrigating farmland, the reel sprinkler irrigation machine mainly uses the work of the water turbine to recover the PE pipe and the sprinkler truck to complete the irrigation operation. The above-mentioned reel sprinkler irrigation machines have been introduced into my country since the 1990s, and there has been a lack of innovation and improvement for a long time. Judging from the configuration and operating conditions of most of the reel sprinkler irrigation machines currently in use, there are mainly the following problems: [0003] (1) When the existing sprinkler irrigation i...

Problems solved by technology

[0003] (1) When the existing sprinkler irrigation is pulled by the traction device, due to the distance in the field, it is impossible to judge the elongation state of the PE pipe, and there is a situation that the PE pipe may be broken; (2) the current reel sprinkler irrigation machine uses Water turbine drive also has obvious waste problems in water energy utilization. Because the water for sprinkler irrigation has to pass through the water turbine, there is a serious loss of water energy, resulting in a burden on sprinkler irrigation, low work efficiency, and high energy consumption. It meets the requirements of agricultural energy saving and emission reduction and is not conducive to the promotion of reel type sprinkler irrigation machines; (3) the existing reel type sprinkler irrigation machines have higher requirements on the water quality of irrigation water sources. When the sediment content in the water source is high, the water contained in the Sediment is easily caught between the blades of the water turbine and the inner wall, causing the water turbine to fail to rotate normally; (4) The speed regulating device and the gear release device of the existing reel type sprinkler adjust the diaphragm tongue of the water turbine through a mechanical linkage mechanism. The speed can be adjusted by the opening degree, and at the same time, the meshing gear in the gearbox is cut off through the connecting rod mechanism to realize the disengagement. These connecting rod devices and the structures associated with them cause the overall structure of the sprinkler to be complicated. The use will affect the reliability of the action; (5) the existing reel type irrigation machine is rarely driven by a motor, and it cannot achieve stable and precise control in the action of recycling the PE pipe, and it is prone to fluctuations, making the spraying effect relatively poor. Poor and the degree of automation control is poor, mainly reflected in the relatively uneven spraying uniformity
