Description
Technical field
Fish device is crossed the present invention relates to a kind of dam, more particularly to a kind of water power combination drive upset rises fish device.
Background technology
The improvement and exploitation of current China water resource enter the new stage, have built more next on the great rivers of China
More dams and other flow blocking buildings.After setting lock due to being built a dam on river, the continuity in former river is blocked, changed
The intrinsic natural characteristic in river, to water environment and the water ecological environment condition producing ratio large effect of gate dam upstream and downstream.One
As for, after flow blocking gate dam is built, Habitat for Fish environmental factor (such as water level, flow, water temperature) will occur change, can be right
Fish movement produces material impact, may directly result in the extinction of some anadromous migrate fish populations.Therefore, with people
Environmental protection consciousness enhanced today, rational fish pass structure should be set up while dam is built, migration is ensured with this
The continuity of fish.And existing its limitation of several fish pass can only reduce in fish pass flow rate of water flow and fish pass in flow velocity extremely
Unstable, while the dash facility inside fish pass has also blocked the migration route of fish, therefore fish is difficult by fish pass in practice,
So it is less efficient to cross fish.
The content of the invention
The invention aims to realize that liter fish device can continuously work to reach migrant success migration, together
The purpose of Shi Tixian high-efficient water uses and a kind of water power combination drive upset is provided and rises a fish device.
The object of the present invention is achieved like this：Including being arranged on two L-type supporting plates in dam downstream, being arranged on two

As the region for concentrating slow current, for attracting migrant.Two pieces of L-type supporting plates 1 and the perforate of water surface contact position, between Kong Yukong
Position should match with the model of first bearing seat 13, and the size in hole should be somewhat more a little bigger than the diameter of screw, first bearing seat 13 and L-type
Supporting plate 1 is fixed by screw and nut.Screw should be able to match with the model of nut.First power transmission shaft 14 is located at sustained height
In first bearing seat 13, by carrying screw locking in first bearing seat 13, reduce and turn to understand frictional resistance.
Placement second bearing seat 11 at the position high as dam of L-type supporting plate 1, the utilization of second driving shaft 12 screw,
Nut is fixed through second bearing seat 11.
In the top of L-type supporting plate 1 placement 3rd bearing seat 10, motive power plate 6 is placed in 3rd bearing seat 10 and L-type branch
Between fagging 1, the 3rd power transmission shaft 4 is fixed using screw, nut through 3rd bearing seat 10.3rd power transmission shaft 4 is located at same
On the 3rd bearing seat 10 of height, by carrying screw locking on 3rd bearing seat 10.Motor 8 is embedded on motive power plate 6,
The rotating shaft for being exposed motor 8 using narrow synchronous belt mechanism 5 and the 3rd power transmission shaft 4 outside L-type supporting plate 1 constitute transmission
System, narrow synchronous belt mechanism 5 draws length sync strip length according to the axle center of the 3rd power transmission shaft 4 and the axle center distance of motor 8.
First synchronizing wheel 17, the 3rd synchronizing wheel 15 are utilized respectively wheel and tighten up a screw locking installed in the first power transmission shaft 14, second
On power transmission shaft 12, the second synchronizing wheel 16 is tightened up a screw using wheel and is locked on second driving shaft 12.The external diameter of bearing should be with synchronizing wheel
Internal diameter be consistent.Timing Belt wide 3 is rotated together with three synchronizing wheels, and the parameter such as number of teeth of synchronizing wheel should be with the ginseng of Timing Belt wide 3
Number matches.
The present invention is provided with three power transmission shafts, and corresponding synchronizing wheel is respectively installed with power transmission shaft, is provided with synchronizing wheel
Timing Belt wide, is evenly arranged with wedge-shaped hopper on Timing Belt wide, and wedge-shaped hopper is equal with the distance between wedge-shaped hopper,
It is equally spaced, three positions of power transmission shafts set the fish, situation about will not interfere excessively that can effectively realize hopper.
Wedge-shaped hopper 2 is wedge shaped to be easy to scoop fish, the back side of hopper 2 with horizontal line into 30 °, when hopper 2 is conveyed into upstream
When, fish is just taken advantage of a situation and has flowed out hopper 2, has one on the dam of upstream with horizontal line into 120 ° of slide 7 of unloading fishes.120 ° of slide of unloading fishes
7 is mutually neat with the back side of hopper 2, and fish falls on the hopper 2 coplanar with slide 7 of unloading fishes, and the slow pool in upstream is flowed into along current.Scoop
Fish face is parallel with Timing Belt wide 3, scoops fish face top and opens a little hole, flows out unnecessary water, so as to reduce weight, is more beneficial for width
The transmission of Timing Belt 3, and improved fish rate.Place hopper 2 at equal intervals on Timing Belt wide 3, distance should ensure that hopper 2
Quantity can meet maximum mantissa during local migrant migration.Between hopper 2 and Timing Belt wide 3 one metaplasia is answered in processing
Produce, i.e., hopper 2 and Timing Belt wide 3 should be one.
Shock plate 9 is connection dam lock hole, upper water is flowed in shock plate 9 along plate, and then impacts the backwater of hopper 2
Face, there is provided some mechanical energy of the rotation of hopper 2, while also completes the energy dissipating effect of upper water, by secondary utilization energy
The current of loss are worked as and draw fish stream.
Fish device is crossed the present invention relates to a kind of new dam, remedying for the facilities such as fish pass is not built and is arranged especially as existing
Impose and the fish device of crossing of newly-built dam is newly selected.
The present invention proposes a kind of circulation upset for utilizing slow current to attract migrant and rises fish device, of the invention by hopper
Structure is optimized, and hopper is not only only scooped the function of fish, and in the presence of water impact hopper opposite side, make fish
Road rotates around fixing axle, reaches circulation and scoops the purpose that fish send fish, while upstream water slug hopper back side, plays to device and push away
Action is used.And because the water of upstream slows down by impact velocity, fish inlet just flow out it is gentle draw fish stream, enable fish by
Gentle current attract, and automatically push up during water swims hopper.The both sides for being placed in dam vertically of the invention, upper water are passed through into lock
Operated on the accessory that hole flows in the present invention, slow current form slow water flow region in downstream fish inlet.
The water of dam upstream is introduced in shock plate by lock hole through rebound, the water slug hopper back side with potential energy,
Moment of torsion is produced to device, meanwhile, upstream motor provides certain mechanical energy, and both rotate common servicing unit.By multiple
After hopper back side energy dissipating, water speed slows down, and forming a Kuai Huan current area in downstream attracts migrant, is successfully attracting migrant
Afterwards, continuously be scooped into for fish by hopper, and takes upstream to.When reaching peak, fish and water are just taken advantage of a situation and have flowed out hopper, upstream dam
On have one with horizontal line into 120 ° of slide of unloading fishes.120 ° of unload fishes slide and hopper back side is mutually neat, fish fall with cunning of unloading fishes
On the coplanar hopper of ladder, the slow pool in upstream is flowed into along current, without being again brought up downstream by current.
