The specific embodiment
Below in conjunction with accompanying drawing, for example the utility model is described in more detail:
In conjunction with Fig. 1~6, the utility model shutter pressure rotary valve fish pass, comprise pipe side wall 1, rotary valve, pipe side wall 1 comprises the cylinder side wall at middle part and the convergent sidewall at cylinder side wall two ends, rotary valve comprises blade 2, main shaft 7, swivel bolt 4, large fixed pulley 14, crossbeam 9, leaflet grid unit, leaflet grid unit comprises leaflet grid 3, rope 12, one end of blade 2 is fixed on main shaft 7, swivel bolt 4 bottoms are arranged on 7 li, main shaft by screw thread, on blade 2, hole is set, leaflet grid 3 are by little cascade axis 5, bearing 6 is arranged in hole, between leaflet grid 3 and blade 2, back-moving spring is installed, on blade 2 with the perpendicular direction of little cascade axis 5 by hold-down nut 10 fixed cross beams 9, little fixed pulley 11 is installed on crossbeam 9, the other marline through hole 13 that arranges of little fixed pulley 11, large fixed pulley 14 is installed on blade 2, on main shaft 7, have large rope through hole 8, rope lead ring 15 is set on leaflet grid 3, rope 12 one end are wrapped on swivel bolt 4, rope 12 other ends are successively through large rope through hole 8, be wound around large fixed pulley 14, little fixed pulley 11, through marline through hole 13, finally by rope lead ring 15, connect leaflet grid 3, rotary valve is arranged on cylinder inner wall place.
The utility model blinds Gate pressure rotary valve fish pass has rotary valve, and leaflet grid control device and pipeline 1 form.Rotary valve is arranged in pipeline 1 middle cylinder place, and control device is arranged on rotary valve.
1) rotary valve is comprised of blade 2, leaflet grid 3, main shaft 7.Four blade 2 intervals in 90 ° with square hole are fixed on main shaft 7.The some leaflet grid 3 of each blade parallel installation in 2 upper aperture places (take 4 in figure as example).Leaflet grid 3 are bigger, square hole can be covered, and make it possess the feature of unidirectional switching.The rotating shaft 5 of leaflet grid and main shaft 7 are arranged in parallel.
2) control device of blinds Gate pressure rotary valve fish pass is comprised of swivel bolt 4 and rope 12.Rope 12 one end are connected with leaflet grid 3, and the other end walks around the little fixed pulley 11 being arranged on leaflet grid 3 and the main shaft 7 that passes hollow is connected with the swivel bolt 4 on main shaft.The control principle of control device is by swivel bolt 4, and tensioning and payout 12 are controlled leaflet grid 3 and opened and closed angle.
3) shutter spinning force rotary valve fish pass pipeline 1 is approximately fusiformis, and centre is cylindrical shape, and both ends open is gradually little.
In conjunction with Fig. 2 and Fig. 3, the control principle of shutter spinning force rotary valve fish pass is:
For meeting the demand of straddling fish stocks to different in flow rate, need to change the opening angle of leaflet grid 3, this process completes by control device.When leaflet grid 3 opening angles are fixedly time, rotary valve rotates with fixed rotating speed, and in fish pass, flow velocity is a certain fixed value.
The increase opening angle of take is example, is rotated counterclockwise and controls bolt 4, on bolt 4, moves, because rope 12 one end are connected and can mutually rotate with bolt 4 lower ends, rope 12 other ends are connected with leaflet grid 3, the linear displacement of bolt 4 are converted into the angular displacement of leaflet grid 3, and the maximum opening angle of leaflet grid 3 reduces.After the maximum opening angle of leaflet grid 3 diminishes, the area difference of simultaneously meeting two blades 2 of stream reduces, and the moment acting on rotary valve diminishes, and rotary valve rotating speed reduces, and fish pass flow velocity also decreases.The operation that increases flow velocity is contrary.
This fish pass has the controlled feature of flow velocity, broken the pattern that traditional fish pass flow velocity is unstable and unique flow velocity can only be provided, by controlling rotary valve, thereby make flow speed stability in fish pass, can be simultaneously that the different fish migration efficiency that makes fish pass cross fish that facilitates improves greatly according to the different habits of fish, on barrage building, there is good actual application prospect in the future.
A kind of shutter spinning force of the utility model rotary valve fish pass, is comprised of rotary valve, control device and pipeline 1 etc., and rotary valve is comprised of four symmetrical bladings 2, on each blade 2, be furnished with can only unidirectional switching leaflet grid 3.By changing the angle of leaflet grid 3 unlatchings, can change the area difference of two blades 2 of simultaneously meeting stream, thereby change the rotating speed of rotary valve, finally reach the object that changes flow velocity in pipeline.The change of the leaflet grid 3 opening angle sizes of this kind of fish pass is completed by swivel bolt 4 drag ropes 12.
On rotary valve blade, be furnished with leaflet grid 3 and only can unidirectionally open.
Rotary valve has three to five blades 2 to form.
