Aquaculture turn-scoop-type wave generator

Abstract

An aquaculture turn-scoop-type wave generator includes a floating bracket body, a gear motor and a wave generating mechanism. The floating bracket includes a base buried in bottom soil of a pool, a telescopic rack mounted on the base and being adjustable in length for arranging the gear motor, and a buoying device floating on the surface of the pool. The wave generating mechanism comprises a rotating arm fixed on the gear motor and two webs driven by the rotating arm to push water. The aquaculture turn-scoop-type wave generator with the structural design can generate large flows of water, large-size vortex and large-scale waves, can quickly promote uniform distribution of dissolved oxygen, and can improve breeding effectiveness and reduce breeding costs because current flow range is much larger than a normal waterwheel aerator.

Description

technical field [0001] The invention relates to a water wave generator, in particular to a scoop-type water wave generator for aquaculture. Background technique [0002] Most of the existing aeration equipment used in aquaculture is designed for high speed. For example, the common impeller-type water wheel aerator mainly uses the high-speed rotation of the flat blade to slap the water surface to generate water splashes and water flow, and uses water spray to increase water and air. However, because the generated water flow is not large, it is difficult to take away the water body with high dissolved oxygen immediately, so that some water splashes fall into the water and are kicked up again, resulting in a waste of electric energy. Furthermore, because the water pumping range of the water wheel aerator is only limited to the vicinity of the water surface where the amount of dissolved oxygen is already high, after fetching water, the dissolved oxygen is mainly diffused to the ...

Problems solved by technology

[0002] Most of the existing aeration equipment used in aquaculture is designed for high speed. For example, the common impeller-type water wheel aerator mainly uses the high-speed rotation of the flat blade to slap the water surface to generate water splashes and water flow, and uses water spray to increase water and air. The contact area, but because the water flow generated is not large, it is difficult to take away the water body with high dissolved oxygen immediately, so that some water splashes fall into the water and are kicked up again, resulting in a waste of electric energy

Furthermore, because the water pumping range of the water wheel aerator is only limited to the vicinity of the water surface where the amount of dissolved oxygen is already high, after fetching water, the dissolved oxygen is mainly diffused to the depth of the pool through diffusion, which is a kind of Relatively slow process with poor efficiency

[0003] In addition, the high-speed design of the aeration equipment and the way it converts electrical energy into fluid mechanical energy have disadvantages such as low energy conversion efficiency, energy concentration in a small amount of water, lack of large-scale convection mechanism, and uneven distribution of dissolved oxygen, so that it is applied to larger In large-scale outdoor aquaculture ponds, it is often necessary to win by quantity, which makes the aeration equipment purchase cost and power consumption cost of the aquaculture industry remain high
