Portable closed openness-controllable farmland irrigation gate

Abstract

The invention relates to a farmland irrigation gate, in particular to a portable closed openness-controllable farmland irrigation gate. The portable closed openness-controllable farmland irrigation gate comprises a gate plate and a gate frame, wherein the gate frame comprises a gate frame main body and a gate frame cover plate. The gate frame main body comprises a gate frame main body panel and rims arranged on the left and right sides and the bottom of the panel, and a gate hole is formed in the middle part of the gate frame main body panel. The gate frame cover plate is of an n-shaped structure formed by a horizontal plate and vertical plates, and the vertical plates are respectively and correspondingly fixedly connected with the rims. Wedge-shaped bulges B are arranged on the lower partof one side of a surface, back to the water, of each vertical plate on two sides of the gate frame cover plate; wedge-shaped bulges A are respectively arranged on the left and right sides of the upper part of the gate plate, and the two wedge-shaped bulges A respectively correspond to the positions of the vertical plates on the left and right sides; and the inner side wall of the left side rim, or the right side rim of the gate frame main body is a serrated structure to form a plurality of concave steps for holding the gate plate. The portable closed openness-controllable farmland irrigationgate provided by the invention is simple to install and low in manufacturing cost, and light and convenient to open and close without obvious friction resistance; when the gate plate is closed, the gate plate is closely attached on the rear side of a gate slot, so that the water stopping effect is good; the gate plate cannot be pulled out of the gate frame, so that the loss of the gate plate can be prevented; and different openness can be controlled, thereby facilitating the water application management.

Description

technical field [0001] The invention relates to a farmland irrigation gate, in particular to a light, airtight and controllable open-degree farmland irrigation gate, which is mainly used as a water gate (that is, a farm gate) at the head of a farm canal or a canal in a field, or a gate for entering the field. Background technique [0002] After years of water-saving renovation in irrigation areas and farmland water conservancy construction, most irrigation channels in various irrigation areas have been lined with anti-seepage, and most of the canal buildings have been renovated. The water-saving level of irrigation areas has been significantly improved. There is no satisfactory solution to the "km" problem. Although there are many types of field gates currently in practical use, the shortage of field irrigation gates with economical, practical and superior performance is very rare. The more commonly used concrete plug-in gate, although the cost is lower, but the water-stop ...

For the gate, if the gate frame is loose, the water-tightness will not be good; if the gate frame is narrow and tight, it will be difficult to open and close the gate plate, and the gate plate can be pulled out and easily lost
