Problems solved by technology

[0003] In the process of fish farming, fish are often sick or damaged. Such fish are generally difficult to collect in water, so they will pollute the water body of farmed fish and affect normal farming. Therefore, how to conveniently realize the The collection of fish is an important part of fish farming

Embodiment 1

[0020] Such as Figure 1~3 As shown, the collection device for aquaculture sick fish, the collection device is a collection column 1 arranged in the water, one end of the collection column 1 is connected with a sewage pipe 3, the collection column 1 is arranged obliquely and the side with the sewage pipe 3 is lower, collecting There is a collection space 7 inside the column 1, and a collection shovel 2 is distributed on the surface of the collection column 1. A rotating plug 6 is hinged at the connection between the collection column 1 and the collection shovel 2. The rotating plug 6 is used to change the sewage inlet arranged on the surface of the collection column 1. 5 open and close state. The collection device is set in the water body, which has little impact on the normal breeding of fish, and the collected sick fish can be directly discharged from the sewage pipe 3 without consuming too much manpower and material resources, which can effectively reduce the cost of breedi...

Embodiment 2

[0028] Such as Figure 4 As shown, this embodiment is a further optimization scheme based on Embodiment 1: the middle part of the anti-friction block 10 is a water storage area 12, the inside of the water storage area 12 is provided with a sponge column 13, and the two sides of the anti-friction block 10 are water in and out. Zone 11, "Z" shaped channel 14 is provided inside the zone 11 for entering and exiting water. During the rotation of the collection shovel 2, when the collection shovel 2 rotates close to the bottom surface, the anti-friction block 10 is squeezed, and the internal water body is extruded after the sponge column 13 is squeezed, so the internal pressure of the water storage area 12 increases, and the water body flows from The water storage area 12 is sprayed out through the "Z"-shaped channel 14. When the collecting shovel 2 rotates away from the bottom surface, the compression force on the anti-friction block 10 disappears, and the sponge column 13 returns ...

Embodiment 3

[0032] Such as Figure 1~4 As shown, the working principle of the device is as follows: the collection column 1 of the device is placed in a water body 5 cm away from the bottom surface of the culture pond at an angle of 5°, the sewage pipe 3 leads to the outside of the culture pond, and the driving device connected with the rotating shaft 4 is arranged in the culture pond. At the edge of the pond, open the driving device to make the rotating shaft 4 drive the collection column 1 to rotate. During the rotation, the rotating plug 6 constantly changes the opening and closing state of the sewage inlet 5, and the collection shovel 2 collects sick fish or dead fish at the bottom of the breeding pond, and then passes through the inlet. The sewage port 5 is sent into the collection space 7 inside the collection column 1, and the sewage pipe 3 extracts the water body in the collection space 7 through the water pump, so that the inside of the collection space 7 forms a negative pressure...

Abstract

The invention discloses a collection device for sick fish in aquaculture, which belongs to the technical field of aquaculture equipment. The collection device is a collection column arranged in water. One end of the collection column is connected with a sewage pipe. The collection column is arranged obliquely and the side with the sewage pipe is lower There is a collection space inside the collection column, a collection shovel is distributed on the surface of the collection column, and a rotating plug is hinged at the connection between the collection column and the collection shovel, and the rotation plug is used to change the opening and closing state of the sewage inlet arranged on the surface of the collection column. The device has little influence on normal fish breeding, good collection effect and high working efficiency, can realize the collection of diseased fish, residual bait or impurities and can improve water quality and fish breeding survival rate.

Description

technical field [0001] The invention belongs to the technical field of aquaculture equipment, and in particular relates to a device for collecting sick fish in aquaculture. Background technique [0002] Fish breeding, rearing and stocking. Fish farming, also known as aquaculture, fish farming and pisciculture, is important in maintaining food supplies, fishing and expanding fishing areas. Many species have been successfully introduced into new areas through fish farming. There is a type of fish farming that involves keeping goldfish and tropical fish both as a profession and as a hobby. Others include keeping minnows as bait and keeping other fish in private waters. Large quantities of fish are farmed in many parts of the world and are mostly sold commercially. However, only a few species are successfully used for this purpose, including catfish, herring, carp and salmon. [0003] In the process of fish farming, fish are often sick or damaged. Such fish are generally di...
