Abstract

The invention discloses an open trench control drainage device which comprises a deep-buried type lock chamber, a gate and an opening and closing device. The deep-buried type lock chamber comprises a frame structure above a trench bottom and a groove type box structure below the trench bottom, a through hole is arranged on a top end beam of the frame structure, a groove is arranged on a lateral wall on the inside, a through grove inside the groove type box structure and the groove are communicated, and the gate is placed inside the groove type box. The opening and closing device comprises a spiral opening and closing machine and a rigid draw bar, and the spiral opening and closing machine is fixed on a top end beam of the deep-buried type lock chamber. One end of the rigid draw bar penetrates through the through hole on the top end beam of the deep-buried type lock chamber, the other end of the rigid draw bar is hinged with the upper end of the gate, threads are arranged on the rigid draw bar which is spirally connected with the spiral opening and closing machine. The gate of the open trench control drainage device opens from bottom to top to achieve overflow of a gate top and has the advantages of continuously and accurately controlling water level of an agriculture groove.

Description

technical field [0001] The invention relates to a farmland water conservancy technology, and specifically provides an open ditch control drainage device. Background technique [0002] Controlled drainage of farmland can not only dynamically improve the soil moisture status in the field according to the needs of different growth stages of crops, but also greatly reduce the loss of sediment, nitrogen and phosphorus carried by rainfall drainage to reduce its pollution to surface water bodies. At home and abroad, there are many farmland control drainage equipment developed for the form of underground pipe drainage, while the open ditch drainage form adopted in most areas of China lacks corresponding reliable control drainage devices. At the same time, due to the large difference between the two drainage methods, the control device developed for the hidden pipe cannot be simply transplanted to the open ditch. In view of the above problems, it is urgent to develop a drainage cont...
