Flood overflowing and escape preventing device for aquaculture

Abstract

The device comprises a flood overflowing and escape preventing device for aquaculture. The device comprises a tank body with an opening at the upper end, a hole is formed at the lower portion of the tank body and communicated with a drainage pipe, the tank body is arranged at the water bottom, the height of the tank body is the height of the normal water level, the upper end of the tank body is connected with an anti-escape net, and the anti-escape net is arranged along the upper end of the tank body by a circle; and the upper end of the anti-escape net is connected with a floating piece, andwhen the water level is larger than the normal water level, the floating piece floats on the water surface, so that the anti-escape net is unfolded, and water enters the tank body from the anti-escapenet to begin to be drained. The device can be automatically started according to the height of the water level, manual operation is not needed, and the flood season escape prevention effect is good.

Description

Technical field[0001]The invention relates to an anti-escape device for aquatic products, in particular to a flood-escape anti-escape device in ponds or paddy fields and breeding ditch, belonging to the field of aquaculture.Background technique[0002]In the process of aquaculture and integrated rice cultivation, in order to prevent aquatic products from escaping, trap nets or escape walls are often set up around ponds or rice cultivation ditches. However, due to the long distance, a large amount of materials are consumed, and usually Inspection and maintenance are also time-consuming and labor-intensive. When the flood season comes, rain washing is easy to damage it, and the escape prevention performance is reduced, resulting in a large number of aquatic products escaping and large losses.[0003]The patent application number 201821377454.0 discloses an anti-escape netting device for broodstock ponds. The anti-escape netting device for broodstock ponds is used for easy operation. The a...

AI Technical Summary

Problems solved by technology

And because the anti-escape net device of broodstock ponds is limited to anti-escape, under the condition of heavy rain, it is easy to cause local uneven or uneven drainage due to the limitation of topography, pond ridge and field ridge height.

The anti-escape net device for broodstock ponds surrounds the periphery of the pond ridge, and the cost of consumables is high, and the cost will increase with the expansion of the pond area

The anti-escape net device for broodstock ponds is mainly suitable for square ponds, and has certain limitations for irregularly shaped ponds, and it can be seen from the attached drawings of the patent that its anti-escape nets are specially designed for square ponds, not It is suitable for the use of escape prevention in paddy field cultivation

In addition, the anti-escape net device for broodstock ponds is mainly used to prevent broodstock from escaping, and it does not work on fry, fish eggs, etc., which will cause production loss
