Embodiment
As shown in Figure 1, 2, the utility model is a kind of aquaculture tank, and the top of this breeding box 7 is that uncovered, bottom arranges osculum 4, and breeding box 7 open top places are provided with water injection pipe 9, and osculum 4 tops are provided with protective cover 5.In this embodiment; water injection pipe 9 first extends straight down at breeding box 7 open top places; end is to the side wall turning of breeding box 7, curved shape; make the sidewall of the water (flow) direction that sprayed by water injection pipe 9 and breeding box 7 tangent, be conducive to slow down the ecological balance in water body, the protection breeding box 7 of water impact breeding box 7.Breeding box 7 bottoms are downward-sloping to centre by sidewall, be funnel-form, osculum 4 is positioned at funnelform bottom centre, so make osculum 4 be arranged on the extreme lower position in breeding box 7, make the excretion efficiency that the flow rate of water flow of discharging from osculum 4 is fast, ensure refuse.Protective cover 5 is made up of the top cover of arranging up and down and some symmetrically arranged supporting legs, the upper surface of top cover be hemisphere planar, can avoid excremental accumulation, between supporting leg, form and discharge the excreta of material culture and the hole of sewage, but control its hole size, make the material culture can be from wherein not running out of.The protective cover 5 of particular design prevents from, in the time of excretion, material culture is adsorbed on to osculum 4 places, and meanwhile, feet, by the unsettled top cover top of being fixed on osculum 4, allows excreta leak down from the hole between supporting leg.
The topmost innovation of the utility model is: be connected with inverted " F " type pipeline 11 in osculum 4 rear ends, and this inverted " F " type pipeline 11 is made up of front end supervisor, middle arm and rear end arm successively.Concrete: front end supervisor connects osculum 4, by waste water and excreta from the interior discharge of breeding box 7.Middle arm end connecting hose 10, flexible pipe 10 upwards extends, the end of flexible pipe 10 sets out the mouth of a river 17, the height of middle arm is more than or equal to the minimum cultivation liquid level in breeding box 7, and the height of delivery port 17 is highly identical with the liquid level 8 in breeding box 7, realizes the object of changing water.Can be by adjusting the position of flexible pipe 10, delivery port 17 height position more than arm top in the middle of " F " type pipeline 11 is regulated arbitrarily.In this embodiment, flexible pipe 10 internal diameters that delivery port 17 places are corresponding: water injection pipe 9 internal diameters are greater than 2: 1, preferably, more than 3:1, ensure that inflow equals water yield.The utility model adopts the principle of linker at this, and flexible pipe 10 is connected with breeding box 7, and the internal diameter of delivery hose 10 is much larger than the internal diameter of water injection pipe 9, height by adjustment flexible pipe 10, controls the height of the interior liquid level 8 of breeding box 7.Rear end arm end arranges sewage draining exit 18, and sewage draining exit 18 places are provided with normally closed scum cock 13.In this embodiment, the height of sewage draining exit 18 should prop up the internal diameter that bore is less than water injection pipe 9 lower than the height setting of osculum 4, sewage draining exit 18 rear ends, place, ensure that excretion can be less than into the water yield, thereby effectively make the residue of excreta and bait discharge from sewage draining exit 18.
The utility model also provides the liquid level flow control system of above-mentioned aquaculture tank, comprises controller 15, is arranged on the water pump 3 at water injection pipe 9 places and is arranged on the blowdown end signal generator 6 of breeding box 7 inside.Wherein: controller 15 comprises microprocessor and data storage cell, the signal controlling input of microprocessor is connected with blowdown end signal generator 6, signal controlling output is connected with the control module of scum cock 13 and water pump 3.In this embodiment, the signal controlling output of microprocessor is connected with the input of D/A converting unit, and D/A converting unit output is connected with frequency converter 14 input blocks, then the supply terminals of water pump 3 is connected with frequency converter 14 output units.After so connecting, then according to the size of cultivation amount, adopt frequency converter 14 and water pump 3 to regulate the flow of water injection pipe 9.Controller 15 also comprises and the interconnective keyboard input block of microprocessor and display unit.
Blowdown end signal generator 6 is liquid level switches, and it arranges highly fixing, liquid level in the time of breeding box 7 normal operating condition below 8.The setting height of blowdown end signal generator 6 is more than or equal to the minimum cultivation liquid level in breeding box 7, and this setting height is the minimum altitude of breeding box 7 liquid level 8 while draining.In the time that scavenge port 18 is opened, the water in breeding box 7 and excreta can be discharged from scavenge port 18 rapidly, in the time that liquid level 8 drops to the height of blowdown end signal generator 6 liquid level switches, blowdown end signal generator 6 is immediately to controller 15 transmitted signals.
Scum cock 13 is magnetic valves, controls its opening and closing by controller 15, thus time opening and close scavenge port 18.
In addition, water pump 3 front ends on water injection pipe 9 are provided with flowmeter 2, and the signal output part of flowmeter 2 connects the signal input part of microprocessor.
In this embodiment, on water injection pipe 9, water pump 3 front ends are provided with safety valve 1.On the arm of sewage draining exit 18 correspondences, scum cock 18 front ends are provided with safety valve 12.Turn-off after safety valve 1 and 12, just can breeding box 7 and liquid level flow control system thereof be installed and be keeped in repair, can not have too much impact to breeding environment.
Using method of the present utility model is as follows:
Aquaculture water enters water injection pipe 9 from water inlet 16, by safety valve 1, detect feedback data to controller 15 record through flowmeter 2, now has following two kinds of situations:
If present flow rate and setting flow be not in error band, D/A conversion output analog voltage 0 ~ 10V, adopt the output frequency of V/F control mode, change frequency converter 14, control water pump 3 and improve or reduce rotating speed, adjust output flow, flow and setting value in water injection pipe 9 are consistent.
If detect, water injection pipe 9 is without flow, and controller 15 prompt tones are reported to the police and closed scum cock 13.
If the height that the liquid level in breeding box 78 height is set lower than blowdown end signal generator 6 float limit switches finishes excretion, signal generator 6 is to controller 15 transmitted signals, prompt tone Alerts Off scum cock 13, and allow water pump 3 turn round by design load.
Under normal operation, according to the height of number adjustment flexible pipe 10 delivery ports 17 of cultivation amount, to change discharge and be input to controller 15 by keyboard input block, controller 15 changes the output frequency of frequency converter 14, and the rotating speed that changes water pump 3 regulates the flow (flow that flowmeter 2 detects also changes thereupon) in water injection pipe 9.In the time that the liquid level 8 in breeding box 7 highly arrives the height of flexible pipe 10 delivery ports 17, due to the principle of linker, water injection pipe 9 internal diameters are much smaller than the internal diameter of flexible pipe 10 delivery ports 17, now, water flow equals flow of inlet water, reach and controlled the object that inflow changes water, ensured that liquid level 8 height are consistent with the height of delivery port 17.
For preventing from cultivating excreta and bait residual contaminants breeding environment, at regular intervals, the scum cock 13 at scavenge port 18 places is opened in controller 15 timings, timely and effectively refuse is excreted out from scavenge port 18.
