Description
Technical field
The utility model relates to the fish culture field, specially refers to the device of hatching, cultivation fry and fingerling.
Background technology
The incubation equipment of present fry, general long 3-4 rice, wide 2-3 rice, high 1.2-1.5 rice, bottom are low inside and high outside the bottom of a pan structure, and inside bottom has 3-4 delivery port, realize the water body exchange by the delivery port water inlet, outside one side is equipped with the filtration screen window, and too much water is discharged, and the exterior bottom minimum point has the external fry collecting box of a seedling outlet to realize the fry collection.For preventing that fry adds active type air oxygen charging pump because of hypoxia death in hatching process.The design of this incubation equipment meets fish fry hatching Biological Principles, but has following problem: 1, owing to the area that can only build about 10 square metres, so the hatching amount is less; 2, because area is less, fry hatching can only be carried out, fry rearing and breed can not be carried out; 3, owing to the one end water inlet from the bottom, current are difficult to arrive opposite side, so the current exchange is not thorough, influence the fry hatching rate easily; 4, because current and oxygen can not arrive any old place at the bottom of the pond, and the general bottom of assembling behind the fry hatching causes local anoxic to cause fry death easily; 5, because oxygenation equipment is movable sand head, layout is inhomogeneous, also can cause anoxic to cause fry death.
Summary of the invention
The purpose of this utility model is to provide a kind of water inlet and air inlet to adopt the microtubule technology, forms pipe network shape air inlet water inlet bottom the body of pond, makes the device of the thoroughly hatching of exchange in the pond of water, gas, cultivation fry and fingerling.
For achieving the above object, the technical solution of the utility model is:
A kind of hatching, cultivate the device of fry and fingerling, be applicable to the hatching of the fish fry that produces viscosity or microviscosity ovum, described device comprises the pond body, water inlet pipe, air inlet pipe, the water inlet microtubule, the air inlet microtubule, filter screen window, pond face water jet and waterwall, on the body of wall of pond body one side, water inlet pipe is housed, air inlet pipe and pond face water jet, water inlet pipe is connected with the water inlet microtubule that is installed in body bottom, pond, air inlet pipe is connected with the air inlet microtubule that is installed in body bottom, pond, water inlet microtubule and air inlet microtubule are in the arrangement separately of pond body bottom, spacing between water inlet microtubule and the air inlet microtubule is 10-20cm, the spacing of aperture is 3-4cm on water inlet microtubule and the air inlet microtubule, there is 0.2% gradient the bottom of pond body to a side, on the pond body of a side of low side delivery port is arranged.Chi Tike builds up rectangle, polygon or garden shape; Polygon can select 1-2 face wall body that the filtration screen window is set fully; Circular builds filter mantle in pond central authorities, and filter mantle is that reinforced frame supports, and outer cover filters screen window, and filter mantle is up-small and down-big.
The device of described hatching, cultivation fry and fingerling, the body of wall of water inlet pipe and pond, water inlet pipe opposite body is built up bay wall, interior wall is a waterwall, waterwall is lower than outer body of wall 25-30cm, 2-4 gap arranged in the bottom of waterwall, gap is connected with drainpipe, and the filtration screen window is equipped with in the inboard of waterwall, and the area that filters screen window should be greater than 1/2 area of metope.
Good effect of the present utility model is:
1, the equipment after the improvement can not be subjected to area constraints, and size can be used for other like this behind fry hatching arbitrarily, realizes its versatility.
2, the device shaped after the improvement can be diversified, can reasonable use build area.
3, the size of equipment can be determined according to the hatching scale, does not limit size because consider incubation rate.
4, equipment water inlet and the gas handling system after improving adopts the microtubule technology to form pipe network shape air inlet water inlet from the bottom, avoided because of water, gas exchange thoroughly or the bottom dead angle occurs and influence incubation rate and emergence rate.
5, the equipment inboard on the hatchery after the improvement installs a cover sparge pipe additional, can guarantee the water body dissolved oxygen more fully.

Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing 1-3.
Referring to Fig. 1, Fig. 2 and Fig. 3, the pond body 1 of hatching, cultivation fry and fingerling device can be accomplished rectangle, circle and polygon, during the body of circular pond, can filter screen window 7 at pond central authorities dress, during the body of polygon pond, can select the 1-2 face that filtration screen window 7 is installed.Before the hatching, water enters in the pond body 1 by water inlet pipe 2 and the water inlet microtubule 4 that is communicated with it, and when water level in the pond body 1 reached waterwall 9 tops, unnecessary water overflowed from waterwall 9 upper limbs by filtering screen window 7, discharges outside the ponds through the gap 10 of waterwall 9 bottoms.Open gas handling system, gas is emerged from the bottom of pond body 1 by air inlet pipe 3 and the air inlet microtubule 5 that is communicated with it.When water oxygen level is not enough, can open spray system, Chi Shui sprays in the pond by pond face water jet 8, to increase the oxygen content in the water of pond, is convenient to hatching and the fish fry breeding of fry in the pond body 1.Need to take out when hatching good fry, can open delivery port 6, fry is flowed out from delivery port 6 with current.
