Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent measurement and control integrated gates used in farmland irrigation, and more specifically, particularly relates to intelligent measurement and control integrated gates. Background Art

[0002] When farmers are irrigating their fields, they open the gates of small reservoirs, and then draw water from the small reservoirs through canals for irrigation. When irrigation is not needed, they just close the gates of the small reservoirs. The gates are mainly composed of three parts: gate leaves, buried frames, and opening and closing devices. The buried frames fix the gates at the outlet of the small reservoirs, and the opening and closing devices control the lifting of the gate leaves to achieve the release and storage of water in the small reservoirs. Small reservoirs usually also breed some aquatic products such as fish and shrimps. The excrement of these fish and shrimps can fertilize crops during farmland irrigation. In order to prevent fish, shrimp, or some debris and garbage from flowing into the farmland along the canal when the gates are opened to release water, a filter is usually set next to the gate to intercept fish, shrimp, aquatic products, and debris and garbage from entering the farmland.

[0003] The existing application number is: CN202221637490.2. The utility model relates to an intelligent measurement and control integrated gate in the technical field of water conservancy facilities, including a gate body, a gate, an anti-impact plate, a buffer unit, and a displacement sensor. A guide column is vertically provided on the gate body, and a floating block is slidably mounted on the guide column. The floating block is provided with a sensing block used in conjunction with the displacement sensor, and the gate is driven to move vertically by the opening and closing unit. Through the up and down movement of the floating block, and the displacement sensor collects the movement data of the sensing block on the floating block, the opening and closing unit can be controlled to complete the corresponding closing and closing action, without manual opening and closing of the gate, thereby improving work efficiency. In addition, by setting a buffer unit to buffer the swing of the anti-impact plate, when the water flow impacts the gate, the anti-impact plate will buffer the impact of the water waves on the gate, thereby reducing the deformation of the gate.

[0004] Based on the above, in order to prevent small fish fry in small reservoirs from flowing into farmland through the gates during farmland irrigation, the mesh size of the filter is generally very small. When the gates are closed and the small reservoirs begin to store water, floating objects, aquatic plants and other debris in the small reservoirs are easily rushed to the filter under the flow of water in the small reservoirs, and attached to the filter, blocking the tiny mesh size on the filter. When farmland irrigation is needed in the later stage, the filter with blocked mesh size will hinder the passage of water, affecting the efficiency of farmland irrigation. Utility Model Content
