The solid pollutants in the river channel mainly comprise biological solid residues and artificial solid garbage (such as branches, fallen leaves and waste plastics), the solid pollutants are important reasons of river channel pollution and also important reasons of river channel siltation, the solid pollutants are fished, the basic operation of river channel cleaning is realized, the solid pollutants in the prior art are fished trouble, and the solid pollutants in the river channel are difficult to be directly removed by the devices such as filtering, sedimentation and the like in the river channel due to the fact that the river channel has the functional requirements of flood discharge, fish passing and the like. The solid pollutants in the existing riverway are mainly removed by means of manual salvage, sediment cleaning and the like, the removal efficiency is low, and long-term, continuous and stable operation is difficult to realize.
The Chinese patent CN201510529513.6 fish-passing type precipitation filter tank (hereinafter referred to as prior art 1) skillfully solves the problem of fishing the solid waste in the river, but the design does not consider the life habit of the fish, and the following technical defects exist:
technical defect 1, because the prior art 1 does not consider the habit of fish countercurrent and does not consider the guiding effect of water flow on the swimming direction of fish, the water flow direction in a fish passing channel formed by a partition wall I and a partition wall II is downward, the fish is induced by mistake in an upstream direction, the fish passes through a fish-type precipitation filter tank, the fish needs to overcome the instinct of upstream and downstream selection and does not have enough intelligence to make such complicated selection, the fish can only follow the nature of upstream and downstream in most of time, and swim for a long time in situ countercurrent under a filter wall I and the filter wall II, and the swimming is meaningless for the fish to pass through the fish-type precipitation filter tank, has no effective displacement and wastes a large amount of physical energy of the fish.
Technical defect 2, prior art 1's partition wall and river bank position cross the fish space, do not carry out reasonable water pressure design, the solid pollutant that the filter wall was intercepted needs frequently to salvage, leads to the filter screen to block up easily, and then leads to rivers direction to change, and the solid pollutant flows away from the fishway.
Technical defect 3, in the filter wall of the prior art 1, the intercepted solid pollutants directly stay on the filter wall, which easily causes the filter wall to be blocked, so that the filtering capacity of the filter wall is unstable.
Technical defect 7, in the filter wall of prior art 1, the intercepted solid pollutants directly stay on the filter wall, and the solid pollutants are easily embedded on the filter wall due to the pressure of the water flow, so that the solid pollutants are difficult to fish for by the workers, and the embedded solid pollutants need to be cleaned in high frequency risk.
Technical defect 8, as shown in fig. 6 of this specification, N is an area where it is difficult for the fish intelligence of prior art 1 to correctly select a direction, and the correct direction of the fish in the N area is from water to downstream, but the behavior of water reversion during fish migration may cause fish to spell upstream, resulting in a great deal of physical waste, and the filter wall that is pressed by water flow below after the physical failure may be injured or dead.
In conclusion, the prior art 1 has the technical problems of fish physical energy waste, unstable filtering capacity, unfavorable survival and propagation of fish, short service life of a filter wall, difficult cleaning and unsafe.
