River eel temporary rearing equipment with airbag gas filling and space compression

Abstract

The invention relates to the technical field of aquaculture, and discloses river eel temporary rearing equipment with airbag gas filling and space compression. The river eel temporary rearing equipment with airbag gas filling and space compression comprises a water tank. The outer sleeve of the water tank is sleeved with a limited position frame, and the four corners of the lower surface of the limit frame are welded with legs. The outer side of the fixing frame is welded between the four legs, and the upper surface of the fixing frame is in contact with the lower surface of the water tank. The right side wall of the water tank is fixedly connected with the water outlet end of the drain pipe, and the inner wall of the drain pipe and the drain end are adhered with an escape net. The river eel temporary rearing equipment with airbag gas filling and space compression makes use of the setting of the pneumatic mechanism, the position of the movable plate in the water tank controlled by charging and discharging gas, and makes use of the shrinkage of the discharge hose to adapt to the shape of the river eel and grab the river eel through the discharge tube for easily catching the river eel in the tank.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a device for temporarily raising adult river eels using air bag gas filling and space compression for simultaneous confinement. Background technique [0002] River eel is rich in a variety of nutrients and has high medicinal value, so it is favored by diners. With the increase of market demand, river eel has also begun to be cultivated artificially. [0003] The maximum radius of an adult river eel is usually 2 to 3 centimeters. The eel can be caught and sold into the market after it reaches adulthood. The river eel that enters the market needs to be kept out of the breeding environment for temporary digestion by the buyer. The eel has no phosphorus And there is a large amount of mucus attached to the surface, like swimming at the bottom of the water, it is not easy to catch in the holding pond, and the eel holding pond in the prior art cannot be quickly discharged, so there ...

Problems solved by technology

[0003] The maximum radius of an adult river eel is usually 2 to 3 centimeters. The eel can be caught and sold into the market after it reaches adulthood. The river eel that enters the market needs to be kept out of the breeding environment for temporary digestion by the buyer. The eel has no phosphorus And there is a large amount of mucus attached to the surface, like swimming at the bottom of the water, it is not easy to catch in the holding pond, and the eel holding pond in the prior art cannot be quickly discharged, so there is an urgent need for a combination of airbag gas filling and space compression.
