Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to shown in Fig. 1 to Fig. 3, the utility model discloses live fish trapping air lift pump installations, including pump line 10, fish
Platform 20 and gas chamber 30.
Since the depth of water of aquaculture pond is 1.7m, pump line 10 is made of PVC material, caliber 20cm, height 2.5m, pressure requirements
1.0Mpa；The upper and lower end of pump line 10 is open and inner hollow；The lower ending opening 12 of pump line 10 connects a U-tube 40, U-tube 40
The other end be trumpet type fish inlet 41,41 opening upwards of trumpet type fish inlet setting.
Fish platform 20 is cirque structure, and circumferencial direction is equipped with fish outlet 21 and several along the circumferential direction etc.
The railing 22 of spacing setting, the middle part of fish platform 20 are equipped with mounting hole 23, and fish platform 20 passes through a connecting tube 50 and pump line
10 upper end opening 11 connects, and connecting tube 50 is used to the fish and water mixture in pump line 10 being delivered to fish platform 20, connects
One end of pipe 50 is fixedly connected with mounting hole 23, and the other end is set in the upper end opening 11 of pump line 10.
The middle part of gas chamber 30 is equipped with the through-hole (being not drawn into figure) passed through for pump line 10, this through-hole is passed through when pump line is installed,
