Compared with present technology the utility model has following advantage:The utility model relies on gas to drive water body and flows through charging into gas, and dissolved oxygen is very sufficient in the water body, and oxygenated water gets into hatching pail from the bottom thereby guarantee have endlessly in the hatching pail; This mode has promptly guaranteed the abundant flowability of water body, has taken into account the supply of water body dissolved oxygen again, has avoided the appearance at hatching " dead angle ", and installs simple for production, easy row, is adapted to the artificial propagation of different scales; The utility model is simple and easy to do, the fry hatching rate is high, not only suitable demersal egg hatching, and also suitable half buoyancy and the unsticking ovum hatching of producing the viscid egg fish, unrestricted on the hatching scale, be particularly suitable for the small-sized hatching that family selective breeding etc. carries out in the laboratory.
Description of drawings
Fig. 1 is the structural representation of flowing water hatching apparatus of the gas water lift of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1; The flowing water hatching apparatus of the gas water lift of the utility model mainly is made up of parts such as hatching pail 1, second right-angle elbow pipe 2, gas tube 3, first right-angle elbow pipe 6 and guards 7; Bottom at hatching pail 1 is provided with water inlet, on the top sides edge of hatching pail 1 guard 7 is housed; Said first right-angle elbow pipe 6 comprises first vertical segment and first horizontal segment; First horizontal segment is terminal to be connected through connector 8 with the water inlet of hatching pail 1 bottom; First right-angle elbow pipe 6 constitutes a U-shaped pipeline with hatching pail 1, and the height of first vertical segment upper end is higher than the height on hatching pail 1 top sides edge; Said second right-angle elbow pipe 2 comprises second vertical segment and second horizontal segment; The lower end of second vertical segment is immersed in the water; Second horizontal segment is terminal to be connected with the side connector of three-way connection 5; The lower contact of three-way connection 5 is connected the top connection of three-way connection 5 and atmosphere with first vertical segment upper end; Said gas tube 3 inserts certain-length in second vertical segment downwards from the bending place of second right-angle elbow pipe 2, and preferably, the vertical range d of said gas tube 3 lower ends and the second vertical segment lower port extreme higher position is 5 ~ 10cm.
As shown in Figure 1, the bottom of said hatching pail 1 is taper, so that do not produce the dead angle in the hatching pail 1, improves hatching quality.The lower end of said second vertical segment is made as oblique section, thereby can make water from flowing into smoothly the second vertical segment lower end.Said first right-angle elbow pipe 6, second right-angle elbow pipe 2 and gas tube 3 can adopt plastics, aluminum pipe or stainless steel tube to process.Described hatching pail 1 is made of plastic, and the volume of hatching pail 1 can enlarge or dwindle according to practical situations.
As shown in Figure 1; Among the utility model embodiment; Said first right-angle elbow pipe 6 mainly is made up of the downpipe 6a, the first connector 6b and the following tube connector 6c that connect in order; The end of the downpipe 6a and the first connector 6b constitutes described first vertical segment, and the other end of the following tube connector 6c and the first connector 6b constitutes described first horizontal segment; Said second right-angle elbow pipe 2 mainly is made up of the water lift pipe 2a, the second connector 2b and the last tube connector 2c that connect in order; The end of the water lift pipe 2a and the second connector 2b constitutes described second vertical segment; The other end of the last tube connector 2c and the second connector 2b constitutes described second horizontal segment; Open a through hole on the said second connector 2b, gas tube 3 inserts in the water lift pipe 2a from this through hole, and the through hole diameter equates with gas tube 3 external diameters.What the second connector 2b in the illustrated embodiment adopted is three-way connection, and its lower contact is connected with second vertical segment upper end, and its side connector is connected with second horizontal segment, and its top connection is sealed with a lid 4, offers described through hole at the center of lid 4.
During concrete the application, the flowing water hatching apparatus with the utility model is fixed in the hatchery earlier, with the hatching water hatching pail 1 is filled; Gas gets in second vertical segment along gas tube 3; Under the effect of water pressure; Gas can bottom-up motion in second vertical segment (among the figure shown in the arrow); And it is bottom-up mobile to drive water body, because the top connection and atmosphere of three-way connection 5, gas can be overflowed the top connection from three-way connection 5; This moment, current then flowed in first vertical segment of first right-angle elbow pipe 6 downwards because of action of gravity; Because first right-angle elbow pipe 6 constitutes a U-shaped pipeline with hatching pail 1; And the liquid level in first vertical segment is greater than the liquid level of hatching pail 1; Therefore; Get into current in first vertical segment and will be after first vertical segment, first horizontal segment get into hatching pail 1 (the figure shown in the arrow) from hatching pail 1 bottom, the guard 7 from hatching pail 1 top flows out then.
Water body in the hatching apparatus of the utility model is mobile to be to carry out through the mode that gas drives, and dissolved oxygen is very sufficient in the water body, and oxygenated water gets into hatching pail 1 from the bottom thereby have endlessly in the assurance hatching pail 1; This mode has promptly guaranteed the abundant flowability of water body, has taken into account the supply of water body dissolved oxygen again, has avoided the appearance at hatching " dead angle ".Its hatching process is identical with existing hatching facility.Through production testing, this improvement, innovative hatching apparatus do not produce the dead angle, and dissolved oxygen evenly and fully is prone to controlling flow velocity, to ovum, seedling not damaged.Its not only suitable " four large Chinese carps " waited and produces the hatching of semibuoyant egg fish, and suitable carp, crucian carp, megalobrama amblycephala etc. produce the unsticking hatching of viscid egg fish, and suitable Tilapia mossambica etc. produces the demersal egg fish and hatch, and incubation rate can reach more than 90%.
