Roundabout fresh water aquaculture pond device

Abstract

The invention discloses a roundabout fresh water aquaculture pond device comprising a pond; a water treatment device is installed at one end of the pond; multiple water body separating walls are installed inside the pond; the pond is divided into aquaculture water channels comprising multiple water flow channels by the water body separating walls; a lifting suspension bridge feeding mechanism extending to the pond center is installed at one side of the pond; the lifting suspension feeding mechanism comprises a mounting seat; a suspension bridge is hinged to the mounting seat; a traction device which can overturn and lift the suspension bridge is installed on the mounting seat; a feeding device is installed at the front end of the suspension bridge; an angle adjusting mechanism which can adjust the feeding angle of the feeding device. The aim of invention is to overcome the deficiency of the prior art and to provide a roundabout fresh water aquaculture pond device which has simple structure, is capable of keeping good condition of water quality and water oxygen content, and has good cultivation effect, good dispersibility of bait and wide range of feeding.

Description

technical field [0001] The invention relates to a roundabout freshwater aquatic pond cultivation facility. Background technique [0002] Pond culture is one of the main forms of aquaculture. Since the 1970s in China, fish pond culture, shrimp and crab pond culture, and aquaculture fry pond cultivation have flourished successively in China. The aquaculture water body is about 10 billion cubic meters , Such a large scale of farming has made great contributions to the development of my country's aquatic economy. Existing aquaculture ponds are mainly rectangular in shape with a uniform water surface, and the inlet and outlet are arranged at one end of the pond or separately at both ends of the pond. Except for a very small number of aquaculture ponds that are equipped with water stirring and aeration machines, The vast majority of ponds only have obvious water flow channels near the inlet and outlet, and most of the water exchange rate in other places is very low. The corners of...

Problems solved by technology

Existing aquaculture ponds are mainly rectangular in shape with uniform water surface, and the inlet and outlet are arranged at one end of the pond or separately at both ends of the pond. Except for a very small number of aquaculture ponds equipped with water-stirring and oxygen-increasing machines, The vast majority of ponds only have obvious water flow channels near the inlet and outlet, and most of the water exchange rate in other places is very low. The corners of the pond far away from the inlet and outlet often become dead corners, the water quality in the pond is not uniform, and the local area is often hypoxic conditions, the cultured organisms cannot obtain a suitable growth environment, diseases frequently occur, the production speed is slow, and even the breeding capacity decreases, and the production efficiency is low

[0003] In addition, in order to improve the efficiency of breeding work, feeding devices are generally used when feeding feed to the farming area. Due to design defects, the current feeding devices on the market have poor dispersion of bait when feeding, and fish and shrimp need to be concentrated. eat in a small area

it's bad for feeding
