In-water operation fish pond desilting device in saline-alkali soil brackish aquaculture

Abstract

The invention relates to the technical field of fish pond desilting, particularly to an in-water operation fish pond desilting device in saline-alkali soil brackish aquaculture. The fish pond desilting device comprises a ship body, wherein annular guide rails are arranged along the edge of the upper end of the ship body; sliding blocks are matched on the annular guide rails; the outer sides of the sliding blocks are connected with a first lifting mechanism; the bottom end of a first lifting rod in the first lifting mechanism is connected with a slurry pump; the slurry pump is powered by a first waterproof motor; the interior of the first lifting rod is hollow; a silt storage barrel is arranged inside the ship body; and a silt outlet pipe of the slurry pump penetrates through the first lifting rod to extend into the silt storage barrel. According to the fish pond desilting device, a silt absorption pump is utilized to remove silt at the bottom of a fish pond, and when sliding along the annular guide rails, the sliding blocks can drive the silt absorption pump to move around the ship body, so that the silt around the ship body can be absorbed without moving the ship body, and the automatic desilting is achieved; and besides, during desilting, water in the fish pond does not need to be drained, the time and effort are saved, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fish pond dredging, in particular to a fish pond dredging device that can be operated with water in saline-alkali land brackish culture. Background technique [0002] At present, in order to make rational use of saline-alkali land, fish ponds are often built in saline-alkali land, and freshwater fish are raised in brackish water. Because the water in the fish pond has a high salt content, it has a bactericidal effect and effectively improves the survival rate of fish. To provide fish with a good living environment, it is necessary to regularly remove the silt deposited at the bottom of the fish pond. The usual cleaning method is to pump out the water in the fish pond, and then manually use a shovel to shovel the silt away. This method requires more work. Large, low work efficiency, time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to overcome...
