Automatic hydraulic irrigation device

Abstract

The invention belongs to the field of hydraulic irrigation equipment and particularly relates to an automatic hydraulic irrigation device. The automatic hydraulic irrigation device comprises a water channel body, wherein the inner wall of the water channel body is hinged to a buoyancy tank flap valve through a first connecting piece, a first rubber water stop plate is attached to one side of the buoyancy tank flap valve, the upper portion of the buoyancy tank flap valve is provided with an exhaust hole, the middle portion of the buoyancy tank flap valve is provided with a first water inlet hole, and the lower portion of the buoyancy tank flap valve is provided with a first water drain hole. The automatic hydraulic irrigation device further comprises a culvert pipe, wherein the culvert pipe penetrates through the water channel body, the water inlet end of the culvert pipe is matched with the first rubber water stop plate, the water outlet end of the culvert pipe is located above a farmland and is hinged to a water outlet valve through a second connecting piece, a water storage tank is arranged below the water outlet end of the culvert pipe, a spherical floater is arranged in the water storage tank and is connected with the water outlet valve through a connecting piece, the upper hemisphere of the spherical floater is provided with a second water inlet hole, and the lower hemisphere of the spherical floater is provided with a second water outlet hole. The automatic hydraulic irrigation device is free of energy consumption, low in cost, capable of being turned on and turned off automatically according to farmland irrigation demands, and also capable of meeting the demands for various irrigation conditions such as continuous irrigation and rotation irrigation.

Description

technical field [0001] The invention belongs to the field of hydraulic irrigation equipment, in particular to a hydraulic automatic irrigation device. Background technique [0002] In the irrigation area of ​​our country, the structure of the field water inlet on the agricultural canal is very simple. Some water inlets are even formed by agricultural producers destroying the canal. There are a large number of water inlets, and it is time-consuming and labor-intensive to manually operate each water inlet every time the water is turned on or off. However, in traditional production, temporary blockage of the water inlet with mud blocks is also likely to result in lax blockage and waste of water resources. Although there are also some branch canal water intakes that use plastic pipes to draw water, many of these plastic pipes have no valves, which is inconvenient to block and endangers the normal operation of the canal. [0003] At present, the automatic control technology...
