[0002] The white shrimp belongs to the phylum Arthropoda, class Crustacea, genus Penaeus, with thin shell, fat body, tender meat and high meat yield; white shrimp is one of the three most productive shrimp species in the world today. High-quality white shrimp has the characteristics of fast growth rate, wide temperature adaptability, strong disease resistance, etc. It is suitable for artificial high-density breeding and can be cultivated in fresh water after desalination. At present, the sales volume of white shrimp in the domestic and foreign markets is huge and it is very popular among citizens. However, in recent years, the diseases of white shrimp have become increasingly serious with the use of various traditional breeding modes. The outbreak and prevalence of various shrimp diseases, mainly death and white spot disease, have become a restrictive factor in the development of shrimp farming. When breeding shrimp, it is necessary to discharge sewage from the breeding pond, so a backwash sewage discharge device is proposed.

[0003] However, the prior art still has the following problems:

[0004] First, it is troublesome to discharge the waste in the existing shrimp breeding pond, and the sewage discharge effect of the sewage in the breeding pond is poor. The breeding structure does not have a backwash sewage discharge component, which makes it inconvenient to discharge the feces in the breeding pond well, reducing the sewage discharge effect of the sewage discharge process.

[0005] Secondly, when using the backwash sewage discharge method, a manual rotary guide valve is generally used to control the backwash of the water flow. The manual operation method is time-consuming and labor-intensive, and there is no rotating mechanism, which makes it inconvenient to automatically control the rotation of the guide valve plate, reducing the convenience of using the sewage discharge device.

[0006] In view of the above problems, the inventors proposed a backwash sewage discharge device for shrimp farming to solve the above problems. Utility Model Content
