A high-efficiency running water device for aquaculture

Abstract

The invention discloses high-efficiency water-running apparatus used for aquaculture. The apparatus comprises a pool body, covering devices, a driving steel wire, adjusting devices, a gas jetting valve and a gas supply device; the covering devices are symmetrically fixed at the top of the pool body, and each covering device comprises one mounting plate, one driving block, guide rails, fixing blocks, one screw rod and one drive motor; and the guide rails are symmetrically fixed at the top of one corresponding mounting plate, the bottom of each driving block is symmetrically provided with grooves, the guide rails are slidably connected with the interiors of the grooves, the middle part of each driving block is provided with one threaded hole, one driving block is movably connected with one corresponding screw rod through one threaded hole, two ends of each driving block are rotatably connected with two fixing blocks through a bearing, and the fixing blocks and the drive motors are fixedon the mounting plates. According to the high-efficiency water-running device used for the aquaculture disclosed by the invention, through the covering devices and the adjusting devices, oxygen in thegas supply device can be uniformly diffused into a water body; and through oxygen floating, the oxygen is in full contact with the water body, so that efficiency of oxygen dissolution is improved, and concentrations of the oxygen in each area of the water body are more uniform.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-efficiency running water device for aquaculture. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the multiplication of aquatic resources. Aquaculture includes extensive cultivation, intensive cultivation and high-density intensive cultivation. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage f...

AI Technical Summary

Problems solved by technology

[0003] In the process of aquaculture, it is necessary to add oxygen to the water. Most of the existing living water oxygenation devices are stirred on the water surface, and the oxygen is added to the depth of the water body through the flow of the water body. Because the oxygen in the air dissolves in the water body at a slow rate, resulting in The oxygenation efficiency of the water body is low, the oxygenation concentration of the water body is uneven, and the long-term flow of the water body is not conducive to the growth of organisms in the water body
