Abstract

The invention relates to a mechanical counting non-return drainer with a ratchet and belongs to the technical field of ground water drainage facilities in hydraulic engineering. The mechanical counting non-return drainer comprises a valve sleeve, an inner casing, a center tube, a spool, a top cover, the ratchet, a counting disc, a spool post and a filter mesh. The valve sleeve is connected with the bottom of a pond to form a communicator; the inner casing is connected to the inside of the valve sleeve; the inner casing is connected with the valve sleeve through a rubber ring a; the center tube is disposed inside the inner casing; the outside of the center tube is connected with the inner casing; the inside of the center tube is connected with the spool. The ratchet and the counting disc are disposed on the spool inside the center tube and are fixed together. Compared with like products, the mechanical counting non-return drainer has the functions of counting and silt control, is simple in structure and long in service life and has the function of unidirectional return avoidance.

Description

technical field [0001] The invention belongs to the technical field of groundwater drainage facilities in water conservancy projects, and in particular relates to a backstop type drainer with a counting function. Background technique [0002] The backstop drain is a special equipment specially suitable for water conservancy projects such as channels and reservoirs under the condition of high groundwater level. Thickness, saving investment, ensuring structural safety and improving the service life of the structure. And the structure that constitutes backstop type drainer is mainly made up of water inlet chamber, water outlet chamber and backstop dodge door as existing backstop type drainer, and backstop dodge door is positioned between water inlet chamber and water outlet chamber. When the groundwater level is higher than the surface water level, the backstop movable door moves upward and opens, and the water inlet chamber and the water outlet chamber are connected to achiev...
