Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-3 shown.

[0021] An unpowered water circulation device for a fry hatching pond, which is mainly composed of a deflector 1, a microporous tube 2 and a counterweight 3, such as figure 1 As shown, the deflector 1 can be made of a hollow buoyancy plate or a metal plate with a float 4, a plastic plate or a wooden plate. Since it needs to work in water, it is best to use a stainless plate or a plastic plate plus a float. Optimally, the bottom of the deflector 1 can be folded into an L-shaped structure (such as figure 2 ), the microporous tube 2 is fixedly installed on the folded edge of the deflector 1, and the microporous tube 2 is connected to the air source through the trachea 5 (plastic hose can be used) to realize the positioning of the deflector 1 in the hatching tank. The air bubbles generated by the microporous tube 2 push t...

Abstract

The invention discloses a fry incubation pool unpowered water circulating device. The device is characterized by being mainly composed of a flow guide plate (1), a microhole pipe (2) and a balancing weight (3); the microhole pipe (2) is fixed to the flow guide plate (1), the microhole pipe (2) is connected with an air source through an air pipe (5) and achieves positioning of the glow guide plate (1) in an incubation pool, bubbles produced by the microhole pipe (2) push water flow in the incubation pool to obliquely flow upwards along the lower surface of the flow guide plate (1) to that water in the incubation pool can circularly flow from one end to the other end, the balancing weight (3) is installed on the flow guide plate (1), and therefore the side, provided with microhole pipe (2), of the flow guide plate (1) is sunk into water and form an included angle of 15-75 degrees relative to the horizontal plane. The fry incubation pool unpowered water circulating device is simple in structure, convenient to manufacture and install, and beneficial to improving fry incubation rate and enhancing fry immunity.

Description

technical field [0001] The invention relates to an aquaculture technology, in particular to a fry hatching device, in particular to a non-powered water circulation device for a fry hatching pond. Background technique [0002] At present, it is an effective method to artificially incubate some fry with high economic value in hatching ponds. This kind of fry has high requirements on water quality, water temperature and water environment during the hatching process. The indoor artificial hatching tank can realize the measures of avoiding light, constant temperature, water filtration, oxygenation and so on to meet the hatching requirements. Among them, water oxygenation is a commonly used and necessary method. The commonly used method is to place the air cap in the water, and the air cap supplies air through the air pump to increase oxygen in the water. The form is relatively simple, but this method cannot effectively Oxygen in the air penetrates into the water, and the freshne...
