Specific implementation mode
The present invention will be further described in detail with reference to the accompanying drawings and examples.
Embodiment 1：A kind of hydropower station tail water fish lift catches attracting channel, and channel setting is under hydropower station tail water outlet
Trip, the region belong to fish Nesting Zone, by selecting suitable position that can meet the attraction flow velocity of offer fish and tracing back flow velocity
Requirement, including channel body 1, fish inlet 2, side opening shunting section 3, fishing room 13, card slot 4 and above carry mouth 5, and fish inlet 2 is set
It sets in 1 downstream end of channel body, side opening shunting section 3 is arranged at 1 upstream end of channel body, inside side opening shunting section 3
It is provided with gate 6；Channel further includes a water charging system, and the water charging system is by moisturizing sump 7, water pump, water supply pipe 8, benefit
Water breeches pipe and nozzle 9 form, and moisturizing sump 7 is provided on the outside of channel, and water pump is mounted on inside moisturizing sump 7, and with benefit
8 one end of water pipe connects, and 8 other end of water supply pipe connects moisturizing breeches pipe, and the setting of moisturizing breeches pipe connects in channel interior side, moisturizing breeches pipe
Connect nozzle 9；Card slot 4 is provided at 1 middle section position of channel body, 4 inside setting fishing bucket 12 of card slot, 1 top of channel body is set
It is equipped with and carries mouth 5, fishing room 13 is arranged above channel body 1, corresponding with 4 upper and lower position of card slot, and track is provided in card slot 4
11, track 11 is two, and 11 bottom end of track is each attached to bottom in card slot 4, and 11 upper end of track, which passes through, above carries mouth 5 and fishing room 13
Connection, 11 top of track are separately fixed at fishing 13 inside both sides of room, and 12 outside both sides of fishing bucket are provided with draw runner, draw runner and rail
Road 11 matches, and fishing bucket 12 is made to be slided along sliding rail, connection stay cord between room 13 and fishing bucket 12 is fished, by pulling drawstring to make
The lower slider on the rail 11 of bucket 12 to be fished, current divider 10 is provided at fish inlet 2, current divider 10 is formed using concreting,
It is fixed on 2 bottom end of fish inlet, fish inlet 2 is divided into the import of different in width by current divider 10, is carried with being directed to different fish
For different attraction flow velocitys, wall is led in the setting drainage of hydropower station tail water exit, and it is flow dividing structure that wall is led in drainage, in order to generate electricity
After tail water of standing outflow, tail water is kept out and is shunted, impact force is slowed down.
When carrying out fishing operations, when tailrace outlet flow velocity is smaller, 6 standard-sized sheet increase of gate is caught in attracting channel
Flow velocity, to reach flow rate of water flow needed for fish trap；When tailrace outlet flow velocity is larger, influenced more than the tracing back flow velocity of fish
When catching attracting effect, flow and flow rate in attracting channel is caught to reduce by turning down gate 6；When 6 full-gear of gate, lead to
When flow rate of water flow is unable to reach flow rate of water flow needed for fish trap in road, start water charging system, is being caught outside attracting channel by setting
The pumping for water pump of side carries out runner bottom moisturizing through water supply pipe 8 to flat nozzle 9, effectively improves and catches attracting in-channel water stream and face
Underflow speed, to greatly improve in-channel water stream entirety flow velocity, to provide suitable fish trap flow rate of water flow, the shoal of fish swims over to fishing
Struggle against 12 it is inner after by pull drawstring make fishing bucket 12 along sliding rail upward sliding to fishing room 13 along, you can complete fishing operations.
