Filtering water channel beneficial to wild fish protection and riverway cleaning system

Abstract

The invention belongs to the field of water treatment, and particularly relates to a filtering water channel beneficial to wild fish protection. The filtering water channel comprises a main channel, and the water channel comprises an inlet (RK), an outlet (CK), a first induction water channel (S1), a second induction water channel (S2), a first concentration area (S3), a third induction water channel (S4), a second concentration area (S5), a fourth induction water channel (S6), a first rest area (S8), a second rest area (S7), a first fish channel (T1), a second fish channel (T2), a third fishchannel (T3), a fourth fish channel (T4) and a fifth fish channel (T5). The riverway cleaning system is provided with the filtering water channel beneficial to wild fish protection. The filtering water channel has the beneficial effects that the effect is stable, the service life is prolonged, the cost is saved, the human safety is improved, the fish is not injured, and the survival and propagation of migratory propagated fish are facilitated, and a new technical thought is provided.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a filtering water channel and a river channel cleaning system which are beneficial to the protection of wild fish. Background technique [0002] The solid pollutants in the river mainly include biological solid residues and man-made solid waste (such as branches, fallen leaves, waste plastics). Solid pollutants are an important cause of river pollution and also an important cause of river silting. Fishing for solid pollutants is the The basic operation of cleaning is troublesome to catch solid pollutants in the prior art. Since the river course has functional requirements such as flood discharge and fish passing, it is difficult to directly install filtration, sedimentation and other facilities in the river course to remove solid pollutants in the river water. The removal of solid pollutants in existing river courses is mainly through manual salvage, sediment removal an...

AI Technical Summary

Problems solved by technology

[0004] Technical defect 1. Because prior art 1 does not consider the habit of fish countercurrent and the guiding effect of water flow on the swimming direction of fish, the direction of water flow in the fish passage formed by partition wall I and partition wall II is downward , constitutes a wrong inducement for the fish to go upstream, and the fish need to overcome the instinct to go upstream and choose to go downstream if they want to pass through the fish-type sedimentation filter tank. The fish do not have enough intelligence to make such a complicated choice. Most of the time, you can only follow the nature of going upstream, and swim countercurrently under the filter wall I and filter wall II for a long time. This kind of swimming is meaningless for fish passing through the fish-type sedimentation filter tank, and there is no effective displacement. , wasting a lot of physical energy of the fish

[0005] Technical defect 2. The partition wall and the fish passing space of the river bank in the prior art 1 have not been designed with reasonable water pressure. The solid pollutants intercepted by the filter wall need to be frequently salvaged, which will easily lead to the blockage of the filter screen, and then cause the water flow direction to change. change, solid pollutants flow away from fishways

[0006] Technical defect 3. In the filter wall of the prior art 1, the intercepted solid pollutants directly stay on the filter wall, which easily leads to blockage of the filter wall, making the filter capacity of the filter wall unstable

[0007] Technical defect 4. Existing technology 1 does not have a resting space for fish, which easily leads to excessive consumption of fish's physical energy, which is not conducive to the survival and reproduction of migratory fish

[0008] Technical defect 5. In the filter wall of the prior art 1, the intercepted solid pollutants directly stay on the filter wall, resulting in an increase in the thrust of the water flow through the filter wall, which is not conducive to the maintenance of the life of the filter wall, and the life is low

[0009] Technical defect 6. In the filter wall of the prior art 1, the intercepted solid pollutants directly stay on the filter wall. When the staff fish out, they need to overcome the huge theory of water flow, and there is a problem of difficulty in fishing, which wastes manpower.

[0010] Technical defect 7. In the filter wall of the prior art 1, the intercepted solid pollutants directly stay on the filter wall, and the solid pollutants are easily embedded in the filter wall due to the pressure of the water flow, which makes it difficult for the staff to fish and requires high frequency. If the staff falls into the face of the filter wall facing the water flow, it may be pressed against the filter wall by the water flow, resulting in life-threatening and unsafe

[0011] Technical defect 8, as shown in the attached description of this application Image 6 As shown, N is the area where the intelligence of the fish in the prior art 1 is difficult to correctly choose the direction. The correct direction of the fish in the N area is to go downstream downstream, but the upstream habit of the fish when migrating will cause the fish to go upstream desperately, resulting in a lot of physical strength waste, and after physical exhaustion, it is easy to be pressed by the water flow on the filter wall below, causing injury or death

[0012] In summary, prior art 1 has the technical problems of wasting fish physical energy, unstable filtration capacity, unfavorable survival and reproduction of fish, low service life of the filter wall, difficult cleaning, and unsafety
