The invention discloses a gate opening and closing device for a small farmland water conservancy project. The gate opening and closing device comprises a transmission mechanism, a control pane, a display screen, a worm gear and a pressure sensor; an upper cover is fixedly arranged at the top of a supporting frame, and the transmission mechanism is inlaid on the outer side of the upper cover; a handle is arranged on one side of the transmission mechanism, and a motor is installed on the other side of the transmission mechanism; the control panel is fixedly arranged on the outer side of the supporting frame, and the display screen is arranged on one side of the control panel; the worm gear and bearings are all inlaid in an inner cavity of the upper cover, and moreover, the bearings are arranged on the two sides of the worm gear; and a bearing nut is arranged in the inner cavity of the upper cover, a lifting hole is formed in the bottom of a screw rod, and the pressure sensor is inlaid inan inner cavity of the bottom of the screw rod. According to the gate opening and closing device for the small farmland water conservancy project, the pressure sensor is arranged to detect the the weight of a gate, judge the damage degree of the gate and judge whether barriers exist on the two sides of the gate or not; and an automatic alarm device is arranged in an inlaid mode, if the barriers exist on the two sides of the gate, an alarm is automatically given.
Description
technical field [0001] The invention relates to the technical field of farmland water conservancy projects, in particular to a gate opening and closing device for small farmland water conservancy projects. Background technique [0002] In small-scale farmland water conservancy, the gate is an essential water conservancy control device, which is used to close and open the control facility of the drainage channel. An important part of hydraulic structures, it can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc. The gate hoist is a hydraulic machinery product gate hoist. It is related to the normal operation of hydraulic structures. In addition to meeting the design requirements of general hoisting machinery, it has special significance for safe and reliable work and flexible and convenient operation. [0003] In the existing water conservancy projects, the gates will be damaged to varying degrees such as corros...
