Description

Technical Field

[0001] The invention relates to the field of shrimp breeding equipment, in particular to a sewage discharge structure for a breeding pond. Background Art

[0002] Shrimp farming is the pillar industry of my country's aquaculture industry; although my country's aquaculture industry has reached the international leading level in scale and output, the sustainable development of the industry still faces severe challenges. With the development of aquaculture, water environment and resource problems are becoming increasingly severe. The environmental conditions of aquaculture waters are constantly deteriorating, because the untreated industrial "three wastes", domestic water, and agricultural water entering the water body cause a series of deterioration in water quality, which first endangers the aquatic organisms, resulting in a decline in fishery resources, an increase in diseases, and the failure of aquaculture. Today's water environment is severely polluted, so the aquaculture environment has further deteriorated, leading to a continuous increase in the occurrence of diseases, and a large amount of drugs and agents are invested in the aquaculture process, which further disrupts the water system and destroys the ecological adjustment. Common diseases of shrimp: viral diseases include WSD, YHV, TSV and IHHNV, etc. Bacterial diseases include red leg disease, gill rot, blindness, juvenile vibriosis and aeromonas, etc. Parasitic diseases include microsporidiosis, monosporidiosis and fixed ciliates, etc.

[0003] At present, central sewage discharge facilities are often used to discharge aquaculture wastewater during shrimp farming. However, during the farming process, shrimps may die due to diseases or a large number of shrimps may molt and block the sewage screen, making it impossible to discharge the wastewater. If the wastewater cannot be removed manually in time, it will cause water infection, and manual work is required to clean the sewage screen, which is time-consuming and labor-intensive.

[0004] Therefore, there is an urgent need for a sewage discharge structure for aquaculture ponds that can solve the problem of poor sewage discharge effect in existing factory-based aquaculture ponds. Summary of the invention

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The purpose of the present invention is to provide a sewage discharge structure for a culture pond to solve the problem of poor sewage discharge effect in existing industrial culture ponds.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Embodiment 1:

[0023] This embodiment provides a sewage discharge structure for a breeding pond, such as Figure 1 and 2 As shown, it comprises a breeding pond 1, a core tube 2 is provided through the bottom of the breeding pond 1, a sewage hole 8 is provided at the position above the bottom of the breeding pond 1, and a sewage control device 10 is connected to the bottom of the core tube 2 through a sewage pipe 9;

[0024] A slide 7 is provided on the lower side wall of the core tube 2, a crossbeam 4 is slidably provided in the slide 7, a shield 3 is connected to one end of the crossbeam 4, a gap is provided in the side wall of the shield, the shield 3 is slidably covered on the outside of the core tube 2, a connecting rod 5 is connected to the other end of the crossbeam 4, the connecting rod 5 is located inside the core tube 2, a floating ball 6 is connected to the bottom end of the connecting rod 5, a throat plate 11 is also provided in the core tube 2, and the upper surface of the throat plate 11 is not higher than the bottom of the culture pond 1; when the floating ball 6 floats up, there is a gap between the bottom of the shield 3 and the bottom of the culture pond 1; when the floating ball 6 sinks, the bottom of the shield 3 contacts the bottom of the culture pond 1.

[0025] Specifically, the density of the shield 3 is less than the density of water, so that the shield 3 can float in the culture pond 1 in a non-discharge state.

[0026] Furthermore, the width of the slits in the side walls of the shield 3 is smaller than the minimum size of the cultured shrimps to prevent the live shrimps from escaping through the slits.

[0027] Furthermore, a lamp 12 is provided in the protective cover 3, and the lamp 12 is connected to an external power source through a cable 13. The lamp can be lit for a period of time before sewage discharge. Since shrimps are generally afraid of bright light, the shrimps that enter the protective cover 3 in advance can be driven out of the protective cover.

[0028] Furthermore, the sewage control device 10 adopts a valve. In other embodiments, a siphon device or a plug-in tube device can also be selected as the sewage control device 10. As long as sewage control can be achieved, it is within the scope of protection of the present invention.

[0029] The present invention provides a sewage discharge structure for a culture pond, and its working principle is as follows: in a non-discharge state, since the density of the shield 3 is less than the density of water, the shield 3 floats in the water, and there is a certain gap between its bottom and the bottom of the culture pond 1, and dead shrimps, shrimp shells and other dirt can be gathered near the core tube 2 in the shield 3 under the action of the water flow. When discharging sewage, the sewage discharge control device 10 is opened, and the water flows into the sewage discharge pipe 9 through the sewage discharge hole 8. Driven by the water flow, the float 6 sinks, and at the same time drives the shield 3 to contact with the bottom of the culture pond 1, and the live shrimps in the culture pond 1 are blocked outside by the shield 3, and the shrimp shells and dead shrimps in the shield 3 will be carried out of the culture pond 1 with the water flow, thereby achieving a good sewage discharge effect.

[0030] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
