A fiberglass tank cultivation device for shellfish seedling cultivation

Abstract

The invention provides a fiberglass water tank cultivation device for shellfish seedling cultivation, comprising a circulating water tank, a water guide plate and a cultivation board; a cultivation board is fixedly installed on the inner side of the cultivation barrel; the other side of the water spray pipe is connected to the The cavities on the inside of the top cover are connected. The setting of the water guide plate and the cultivation barrel is conducive to improving the cultivation effect. When the water sprayed by the nozzle touches the water guide plate during use, because the water guide plate is an inclined structure, part of the water will pass through the cultivation barrel and the water guide. The through hole above the plate embedding flows to the top of the cultivation plate, and then another part of the clear water will continue to flow down through the through hole on the water guide plate, so that it can contact the water guide plate on each layer of the cultivation barrel in turn. During the falling process, the water will evenly flow into each cultivation barrel, greatly reducing the amount of water needed, and will not pollute the shellfish in the lower barrel, improving the cultivation efficiency and more conducive to the growth of shellfish.

Description

technical field [0001] The invention belongs to the technical field of shellfish cultivation equipment, and more specifically relates to a glass fiber reinforced plastic water tank cultivation device for shellfish seedling cultivation. Background technique [0002] At present, there are many breeding areas and breeding bases for seawater shellfish products in the offshore, near the offshore and harbors. The breeding areas of these marine farming areas and breeding bases are often very large, and generally one breeding area or breeding base can reach thousands. With an area of ​​tens of thousands of mu of sea surface, most of the current shellfish are cultured in breeding boxes. [0003] For example, the patent application number is 201210530895.0, which discloses a benthic shellfish culture device, including a rectangular main body plate, wherein: the gap between the main body plates is evenly distributed with culture holes, and each culture hole is formed with an arched att...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a glass fiber reinforced plastic tank cultivation device for shellfish seedling cultivation, to solve the problem that the existing shellfish seedling cultivation cultivation devices are only equipped with a single-layer cultivation plate, the cultivation efficiency is low and more space is required , use more water for cultivation, some multi-layer cultivation equipment can only be cultured in a large area of ​​water, and if a small amount of water is required for circulation cultivation, the cultivation water in the upper layer will flow to the lower layer during the circulation process In the cultivation plate, the water has been used by the shellfish in the upper layer without any filtration, and there are still a lot of impurities in the water, which will adversely affect the growth of the shellfish in the lower layer
