Description

one

The invention relates to the field of hydraulic engineering, in particular to fish pipe structures.

A fish gate is known, which contains a fish storage tray, a working chamber, a fish catching device, an ichthyology site and a raised output tray.

The main disadvantages of the known fish gateway are its low productivity due to the increase in cycle time for maneuvering operations at the ichthyological site, counting and tagging of fish, limited flow rates in the fish collecting tray during the period of transfer of fish to the upstream, due to possible injury to the fish o canvas motive device.

The purpose of the present invention is to increase the productivity of the fish passage.

This goal is achieved by the fact that the upper output tray is formed by two channels connected by a window and equipped with strips. Installed with the possibility of reciprocating movement in the vertical

One of the channels is an extension of the working chamber and is equipped with a trigger device mounted for movement perpendicular to the flow, and the ichthyological platform is located in the second channel.

FIG. 1 schematically depicts a plan for the fish passage in FIG. 2, section A-A of FIG. one; in fig. 3 - section bb FIG. one.

The fish gateway contains a fish storage tray 1, in the grooves 2 of which the bottom 3 and upper 4 closures were removed, forming the working chamber 5 for locking the fish. Behind the working chamber 5 there is a riding, output tray formed by two channels, with channel 6 being the continuation of working chamber 5, and channel 7 ,. having, with channel 6, a common wall 8, is connected with it by a window 9. Channels 6 and 7 are provided with grids 10 and 11, respectively, installed with the possibility of reciprocating motion in a vertical plane. Channel 7 is equipped with an upright 12 in which an ichthyological platform 13 is installed. The accumulative tray 1 is equipped with a trigger device 14, which is installed with the possibility of reciprocating movement along the tray, and the channel b is equipped with an attenuating device 15 that is installed with the possibility of movement perpendicular to the flow. ,

The fish passageway works in the following way.

After a period of attracting fish, the motive device 14 moves to. working chamber 5. The downstream shutter 3 is lowered, and the upper shutter .4 rises, and the fish is moved with an incentive device 14 c into the space enclosed between. Do an incentive device 14, a grill 10, an incentive device 15 and a window 9. The accumulated fish with an incentive device 15 is transferred to channel 7, the incentive device 14 is converted to source polarity. A new attraction cycle begins. At the same time, the ichthyological site 13 rises, the fish are counted and tagged. ; Then, the ichthyology site 13 is lowered into the niche 12, the grill 11 rises, providing free access for the fish to the upstream

fish, to ensure the safe removal of fish from fish shlgo.za, as well as to carry out an unlimited supply of water flow in the fish storage tray, which will increase the efficiency of attracting and storing fish.

Fomula invention
