An on-site ecological water purification weir system based on hydraulic engineering

Abstract

The invention provides a hydraulic engineering based field ecological water purifying weir system, which relates to the environment-friendly technical field, and solves the problem that preliminary cleaning for a filter device cannot be simultaneously realized while a gate is opened and the filter device is pulled out as sealing property cannot be improved while gate stability is improved throughstructural improvement, an un-tight gate closing phenomenon is easily caused by sand particles blocked into a gate slot during gate closing, and an unstable gate positioning phenomenon is easily caused by water flow resistance influences during gate opening. The hydraulic engineering based field ecological water purifying weir system comprises a main body frame and a cleaning brush base, wherein one gate is spliced onto the main body frame in a sliding mode. While the gate is pulled, the rear end surface of the gate is fixedly connected to an elastic bayonet lock, the head end of the elastic bayonet lock is matched with a blocking slot, and the head end of the elastic bayonet lock is in blocking connection to the blocking slot after the gate is spliced with a slide slot B, so that a filterbox is in a clean state under action of the cleaning brushing while the gate is upwards pulled.

Description

Technical field[0001]The invention belongs to the technical field of environmental protection technology, and more specifically, relates to an on-site ecological water purification weir system based on a water conservancy project.Background technique[0002]Due to the small rain-collecting area and poor connectivity with the surrounding water systems, river water pollution, small flow and even flow interruption often occur, which seriously affects the ecological environment of the river. Water weirs serve as both "water storage" and "discharge" functions. The hydraulic structures can effectively adjust the water level in front of the dam and the discharge flow, guarantee the ecological flow of the river and other water, and are widely used in the river.[0003]Such as the application number: CN201810754142.5, a bionic ecological water purification weir system, including a water retaining dam, a server and an intelligent terminal, the water retaining dam includes a fixed dam and an adjus...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides an on-site ecological water purification weir system based on water conservancy projects to solve the existing problem that the gates of existing devices are mostly single-layer sealed structures, and it is impossible to realize the gate through structural improvement. The stability is enhanced and the sealing performance is improved at the same time, and the existing device is easy to close the gate due to the influence of sand particles stuck in the gate groove when closing the gate, and the existing manual gate is affected by water flow resistance when opening the gate. It is easy to lead to unstable positioning of the gate; moreover, the structure of the existing device is poor, and it is impossible to realize the preliminary cleaning of the filter device while opening the gate and pulling out the filter device
