Automatic field drainage control device allowing submergence depth to be adjustable
The invention discloses an automatic field drainage control device allowing the submergence depth to be adjustable. The automatic field drainage control device comprises a water tank, a water inlet is formed in one side of the water tank, the height of the top of the water inlet is equal to that of the top of the water tank, the width of the water inlet is equal to the inner width of the water tank, and a drainage opening is formed in the bottom of the water tank and connected with a drainage pipeline; a retaining wall is arranged at the position, close to the water inlet, in the water tank, a hinged shoe is arranged at one side, close to the water inlet, of the retaining wall and connected with a baffle, a weight is fixed to the lower end of the baffle, the width of the baffle is consistent with that of the water inlet, and the baffle makes contact with the two side walls of the water tank. The automatic field drainage control device allowing the submergence depth to be adjustable can automatically control field drainage and set different discharge levels according to needs, and is firm, durable and low in construction cost and maintenance cost.
