Description

TECHNICAL FIELD

[0001] The utility model relates to the field of aquaculture, concretely relates to an aquaculture pond drainage and sewage device. BACKGROUND

[0002] With the vigorous development of aquaculture industry, the density of aquaculture is increasing, the amount of feeding is greatly increased, and a large amount of residual feed, excrement, silt and the like are deposited at the bottom of the breeding pond, wherein the decomposition of microorganisms to organic matter consumes a large amount of oxygen. At the same time, a large amount of toxic intermediate products are produced by the decomposition of organic matter at the bottom of the pond, which can cause chronic poisoning of aquatic animals, inhibit their growth, and even lead to death. A large amount of drugs are continuously put in, and the polluted water at the bottom of the breeding pond cannot be discharged in time, and is often removed only once a year or even once every few years. The production capacity of the aquaculture pond cannot be guaranteed and improved only by increasing oxygen equipment and self-decomposition of the pond. Only by completely exchanging the water at the bottom of the breeding pond can the silt, residual feed and excrement at the bottom be discharged.

[0003] In conventional breeding production, there are two ways to discharge water in the traditional breeding pond. One way of discharging water is to discharge the surface water, which has the advantages of easy observation and convenient operation. However, the surface water is the part of the breeding pond water with the most abundant dissolved oxygen, the least pollution and the best water quality. Discharging the surface water is harmful and useless. The other way of discharging water is to directly discharge through the drainage pipe buried at the bottom of the breeding pond, which has the advantage of directly discharging the bottom pollutants and the polluted water. The disadvantage is that fish, shrimp, crab and water plants are easy to escape from the drainage port or be washed out by strong water pressure, causing fish death and escape, drainage port blockage and other situations, resulting in poor drainage and low efficiency. In addition, the drainage port is at the bottom of the breeding pond, and it is difficult to observe and handle after the situation occurs, which is difficult to operate. Therefore, it is necessary to develop an aquaculture pond sewage collection and discharge device to solve the problems of poor, inconvenient and incomplete drainage and sewage in the traditional aquaculture pond, as well as the escape and injury of aquatic animals during sewage and drainage.

[0004] Although the prior art such as CN207911807U can automatically and zero-energy discharge the bottom pollutants of the breeding pond, it is easy to cause the aquatic products to escape from the drainage port, resulting in the death of the aquatic products. In addition, the drainage port is at the bottom of the breeding pond, and it is difficult to observe and handle after the situation occurs, which is difficult to operate. UTILITY MODEL CONTENTS
