Problems solved by technology

[0002] Dead fish are unavoidable in aquaculture, but in the circulating aquaculture system, due to the high breeding density and low water exchange rate, the color of the water body is dark, and the dead fish will flow to the sewage outlet at the bottom of the pool with the water. It is difficult to salvage, and it is not even easy to be found. If it is not removed in time, it will pollute the water body and breed harmful substances such as bacteria. It will also affect the water out of the fish pond and cause accidents.

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] see Figure 1-Figure 2 When the fish pond 1 is used for normal circulating aquaculture production, the fish-blocking net cover 4 is in a closed state with the bottom of the fish pond, and the fish are isolated in the fish pond outside the fish-blocking net cover 4, and the aquaculture water enters the return pipe 7 through the fish-blocking net cover 4, and then passes through the fish pond. Vertical flow precipitator 2, and finally enter the subsequent water treatment link through the water outlet 11.

[0036] The amount of water circulation produced by normal circulating aquaculture in fish ponds is controlled by the water level maintenance pipe 3 in the vertical flow settler 2, which can adjust the water level difference by adjusting the height of the intubation pipe, thereby achieving the purpose of controlling the flow of the water ...

Abstract

The invention relates to a dead fish collecting device for a circulating aquaculture system, and belongs to the technical field of aquaculture. The dead fish collecting device for the circulating aquaculture system is characterized in that a fish screen (4) is arranged at a water outlet at the bottom of a fishpond (1); a pneumatic means is arranged below the fish screen (4); the pneumatic means is a pneumatic pipe connecting the fish screen (4) and the outside; a first air cylinder (5) internally provided with a first piston (6) is arranged at the end, close to the fish screen (4), of the pneumatic pipe; a second air cylinder (9) internally provided with a second piston (8) is arranged at the end, close to outside, of the pneumatic pipe; the first piston (6) is fixedly connected to the fish screen (4); when a user push or pull the second piston (8), the first piston (6) can be driven to upwardly jack the fish screen (4) or downwardly pull the fish screen (4) for reset; and dead fishes flow out from a circulating water channel below the fish screen (4) when the fish screen (4) is upwardly jacked.

Description

technical field [0001] The invention relates to a device for collecting dead fish used in a circulating aquaculture system, belonging to the technical field of aquaculture. Background technique [0002] Dead fish are unavoidable in aquaculture, but in the circulating aquaculture system, due to the high breeding density and low water exchange rate, the color of the water body is dark, and the dead fish will flow to the sewage outlet at the bottom of the pool with the water. It is difficult to salvage, and it is not even easy to be found. If it is not removed in time, it will pollute the water body and breed harmful substances such as bacteria. It will also affect the water out of the fish pond and cause accidents. [0003] How to realize the salvage of dead fish in the recirculating aquaculture system is a technical problem that needs to be solved urgently in this field. Contents of the invention [0004] The object of the present invention is to provide a device for colle...
