Portable weir applicable to channels and capable of realizing corrugated flow blockage and ecological purification

Abstract

The invention discloses a portable weir applicable to channels and capable of realizing corrugated flow blockage and ecological purification. The weir comprises an outer frame and a cross beam; the outer frame is U-shaped; the cross beam is fixed in the middle of the upper side of the outer frame; the weir comprises corrugated plates, fixing plates, sliding rods, packing balls and waterproof cloth; the four sliding rods are horizontally fixed between the outer frame; openings are formed in four corners of the corrugated plates and four corners of the fixing plates; the corrugated plates and the fixing plates are glidingly connected with the sliding rods; the corrugated plates are pairwise mounted between the fixing plates in backward directions; the packing balls are placed among cracks of the corrugated plates; the waterproof cloth is arranged at the front ends of the fixing plates and the outer frame in reference to the water flow direction; the weir further comprises a motor, speed reducers, screw rods, push plates, a water level sensor and a controller; two ends of the motor are connected with the speed reducers separately; one end of each screw rod is connected with the corresponding speed reducer, and the other end of the screw rod is connected with the corresponding push plate; the water level sensor is mounted at the front end of the outer frame; and the controller is fixed on the cross beam. The weir integrates functions of a water retaining weir and a purifier and has the relatively high portability.

Description

technical field [0001] The invention relates to a portable corrugated flow-blocking ecological purification weir suitable for ditches, which belongs to the technical field of water environment protection. Background technique [0002] In recent years, with the rapid development of my country's industrialization and the further improvement of agricultural intensification, the produced industrial sewage, agricultural sewage and domestic sewage have caused serious damage to the water environment. A large amount of untreated or incompletely treated sewage is discharged into rivers, lakes and other water bodies through various levels of river canal systems, resulting in the overall deterioration of the water quality of rivers and lakes. The source interception and purification of pollutants in all levels of river and canal systems has become an important measure for water environment protection. [0003] River channels and their canal systems are important components of urban na...

Problems solved by technology

Most of the common weir structures are solid dams constructed of reinforced concrete, which are simple to construct and require little investment. However, this type of weir only has a simple function of intercepting and intercepting water, and cannot adapt to the real-time flow characteristics of the canal and the water environment of the canal.
