Description
Technical field
The utility model is related to one kind and expels device, and in particular to a kind of fish and shrimp based on vacuole principle expel device.
Background technology
Bubble is related to the obstruction effect of the nektons such as fish and following three kinds of sensing mechanisms of fish：(1) vision is made
With：Air curtain is formed on after bubble generation, a kind of visual stimulus is produced in the visual field of nekton, visual barrier is formed, caused
Make fish away from air curtain；(2) lateral－line organ tactile is acted on：Formed air curtain compressed air from venthole at a high speed spray when,
Bubble it is upper into motion process all can strong agitation water body, the pressure of water is changed, produce low-frequency vibration (mechanical pressure
Vibration).Vibration can be perceived by the lateral－line organ of fish.Bubble produce speed it is faster, to fish body side line produce impulsive force and touch
Feel that oppressive force is also bigger, dispersion effect is more obvious；(3) the inner ear sense of hearing is acted on：The air-flow quickly gone out from conduit aperture is sent out with water
The motion of current has circulation characteristic near raw strong mixing, aperture, and bubble gradually expands in uphill process, sound wave in bubble
Pressure cycle change causes air vibration and bubble water-outlet face in bubble to occur to crush, and will all produce fixed sound wave, these
Sound wave can cause to frighten and play a part of stopping and driveing to nekton.Therefore need design a kind of based on vacuole principle
And Intercepting effect well expel device.
The content of the invention
The utility model purpose is to provide a kind of fish and shrimp based on vacuole principle to overcome the deficiencies in the prior art
Expel device.
To reach above-mentioned purpose, the technical scheme that the utility model is used for：A kind of fish and shrimp based on vacuole principle
Device is expelled, it is arranged in power plant's water inlet open channel, power plant's water inlet open channel includes dykes and dams and is opened in the dykes and dams
Irrigation canals and ditches, it include be fixed on the trench bottom and offer the escape pipe of multiple steam vents, on the dykes and dams
Booster fan, one end is connected with the outlet tube end and the other end extends to the blast pipe being connected with the booster fan
Road, the check-valves being disposed adjacent on the discharge duct and with the escape pipe and mutually it is electrically connected with the booster fan
The control module connect.
Optimally, it also includes the air tank being connected with the booster fan.
Optimally, it is also equipped with safety valve on the discharge duct between the booster fan and the check-valves.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：The utility model
Fish and shrimp based on vacuole principle expel device, by laying discharge duct in power plant's water inlet open channel air tank are passed through
Booster fan continuous drum into power plant's water inlet open channel, which is supplied gas, to be steeped and forms bubble stream；Bubble is in floating-upward process, volumetric expansion, when
When the height that floats is more than certain altitude, adjacent air bubble is mutually mixed, formation bubble wall, and the air before bubble mixing
Bubble forms bubble fence, and the nektons such as fishes and shrimps are expelled so as to realize.
Brief description of the drawings
Fig. 1 is the structural representation that fish and shrimp of the utility model based on vacuole principle expel device.
Embodiment
The utility model is further elaborated below in conjunction with accompanying drawing.
Fish and shrimp based on vacuole principle as shown in Figure 1 expel device, and it is arranged on (power plant in power plant's water inlet open channel 1
Open channel 1 of intaking is conventional structure, including dykes and dams 11 and the irrigation canals and ditches 12 that are opened in dykes and dams 11), mainly include escape pipe 2,
Discharge duct 4, check-valves 6 and booster fan 7 etc..
Wherein, escape pipe 2 includes being fixed on the bottom of irrigation canals and ditches 12, and whether its top (only opens up stomata at top) open
Provided with multiple steam vents 3；Booster fan 7 is arranged on dykes and dams 11；One end of discharge duct 4 be connected with the end of escape pipe 2 and
The other end is extended to be connected with booster fan 7, so can be through discharge duct 4 to escape pipe 2 using the work of booster fan 7
Drum send air.Check-valves 6 is arranged on discharge duct 4 and is disposed adjacent with escape pipe 2, for preventing seawater through the He of escape pipe 2
Steam vent 3 pours in down a chimney.Control module 8 (can be the control devices such as conventional control cabinet or PLC) is mutually electrically connected with booster fan 7
Connect, for being controlled to its power, so as to control the air mass flow discharged through steam vent 3.It is bright by being intake in power plant
Laying discharge duct enables air tank continuously to be roused into power plant's water inlet open channel by booster fan and supplies gas bubble and form gas in canal
Bubble stream；Bubble is in floating-upward process, volumetric expansion, and when the height that floats is more than certain altitude, adjacent air bubble is mutually mixed,
Bubble wall is formed, and the air bubble before bubble mixing forms bubble fence, so as to realize the drive to nektons such as fishes and shrimps
From.
In the present embodiment, air tank 9 is connected with booster fan 7, is carried for stored air or to the air of pressurization
For buffering.The shape and density (intensity) of bubble wall are the principal elements for determining to stop effect frame, and the density of bubble wall is long by unit
The factors such as the pressure of hole count, the size of gas outlet (aperture) and compressed air spent on escape pipe 2 are determined, therefore are actually made
Used time carries out correspondence adjustment to above-mentioned parameter.Peace is also equipped with discharge duct 4 between booster fan 7 and check-valves 6
Full valve 5, to ensure that whole fish and shrimp expel the trouble free service of device.
Above-described embodiment is only to illustrate technical concepts and features of the present utility model, and its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this,
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover protection domain of the present utility model it
It is interior.
