U-shaped drainage system for intensive culture pond

Abstract

The invention provides an intensive culture pond U-shaped drainage system which comprises an intensive culture pond, a drainage ditch is arranged on one side of the pond, a drainage pipe is embedded between the drainage ditch and the pond, a batch feeder is arranged on the bank side close to the embedded drainage pipe, and a water inlet, close to the inner side of the pond, of the drainage pipe is connected with a first square elbow. The first square elbow is connected with a horizontal pipe with meshes drilled in the periphery, the other end of the horizontal pipe is connected with a second square elbow, and the other end of the second square elbow is sleeved with an insertion pipe; a valve is arranged on the drainage pipe close to a drainage port on the inner side of the drainage ditch, the other end of the valve is connected with a third square elbow, and long pipes with matched diameters and different heights are inserted on the third square elbow. The device has the advantages of being simple in structure, easy and convenient to operate, effective in drainage and pollution discharge, capable of effectively reducing production cost, capable of rapidly and effectively adjusting the water volume and the water quality of the aquaculture pond, capable of improving production efficiency, capable of guaranteeing normal operation of the aquaculture process and the like.

Description

technical field [0001] The invention relates to the field of aquatic animal breeding, in particular to a U-shaped drainage system for intensive breeding ponds. Background technique [0002] Aquaculture is an important part of my country's modern agriculture, making important contributions to ensuring my country's "food security" and prospering rural economic and social development. With the continuous improvement of science and technology, aquaculture technology has been greatly developed. In my country's aquaculture industry, pond culture is one of the most important methods. Due to the high output and higher density of freshwater intensive ponds than ordinary fish ponds, artificial feed is often used for feeding and breeding. In the feeding process, timing, quantitative, qualitative and fixed-point are the basic principles. It is equipped with a feeder. During the feeding process of the feeder, it is inevitable that bait debris and fish excrement will accumulate and depo...

Problems solved by technology

Due to the high yield and higher density of freshwater intensive ponds than ordinary fish ponds, artificial feed is often used for feeding and breeding. During the feeding process, timing, quantification, quality and fixed point are the basic principles. Therefore, the ponds are often fed. It is equipped with a feeding machine. During the feeding process of the feeding machine, residual bait debris and fish excrement will inevitably accumulate and deposit at the bottom of the pond. If they are not removed in time, the water quality will deteriorate and the normal growth of fish will be affected.

In the production of pond aquaculture, it usually relies on cumbersome procedures to replace the pond water body. At the same time, it requires a lot of manpower to regularly remove the residual bait. Some water transfer agents and some equipment are also used to replace some water transfer agents to achieve water recycling in the aquaculture pond. However, These human and material resources are a major part of the increased cost
