Description

I

The invention relates to fish protection devices for water intake structures, preferably in supply channels.

A fish protection device for a water intake structure is known, which contains a mesh chamber in the inlet chamber consisting of articulated: interconnected sections, and a diversion channel 1 and 2.

However (the known device is inefficient, but in operation, interruptions in the water supply are created, since in order to flush the netted cloth, it is necessary to temporarily close the main channel and direct all flow to the fish drainage channel.

The purpose of the invention is to increase the efficiency of the fish bath.

This is achieved by jrro across the canal with a carriage, and the water intake chamber is V-shaped, with the ends of adjacent webs combined with each other and mounted on the carriage, and the free ends of the webs are rigidly fixed in the channel and perforated split walls.

FIG. 1 shows the proposed device in plan (accumulation of fish and garbage in chamber 3 and emptying chamber 2) in FIG. 2 the same, at the moment of transfer from one position to another; in fig. 3 - drive; in fig. 4 - the same at the time of disclosure.

The water intake protection device has a water supply channel 1, water intake chambers 2 and 3, consisting of mesh grids 4 that are pyrrically interconnected, a ramp 5 with a carriage 6, a hopper 7, drain caps 8, deflectors 9, drain channels 10 and 11 and flow formers 12.

The fish protection device intake works as follows.

Claims (2)

When water is pumped from a pumping station, stream-borne debris and fish enter the working chamber and concentrate in accumulator 7. When the amount of accumulated debris and fish reaches a certain limit, the accumulation sensor is activated, which feeds to. Mandu on the carriage drive mechanism 6. The carriage moves to the opposite bank of the channel 1. The walls of the chamber 2 are folded and occupy a parallel position along channel 1, and the accumulator 7 enters the head of the discharge channel 8. After that, the shutters of the accumulator 7 open and simultaneously turn on operation of the flow formers 12. The process of emptying the chambers 2 and the storage device 7 to the discharge channel 10 occurs, while the camera 3 operates in the accumulation mode, then Pcl is repeated. The fish protection device of the water intake facility is useful and will allow to obtain an economic effect in the national economy. Claim 1. A fish protection device for a water intake structure, comprising a water intake chamber consisting of sharinno C1, the meshed genes between each other, and (ih a duct channel, characterized in that, in order to increase the efficiency of fish protection, across the channel an overpass with a carriage, and the water intake chamber is V-shaped, with the ends of adjacent webs combined with each other and fastened to the carriage, and the free ends of the webs are rigidly fixed in the channel and in the vertex of each chamber there is a drive with perforated detachable walls. 2. The device according to claim 1, characterized in that water discharge caps and deflectors are mounted inside the accumulator.Sources of information taken into account during the examination 1.Authorial certificate of the USSR No. 450012, class E02 on 8/08, 1972. 2.
