Description

TECHNICAL FIELD

[0001] The present application relates to a barrel-in-barrel ecological circulation aquaculture system. BACKGROUND

[0002] Modern facility aquaculture is a production mode that uses advanced facility equipment and modern scientific and technological methods to achieve the goals of high quality, high yield, high efficiency, ecology, health and safety. Modern facility aquaculture has become the focus and hotspot of the current development of aquaculture industry, and has attracted widespread attention from the industry and society. The reason is that it represents the development direction of the aquaculture industry. From the perspective of green development of the industry, the tail water treatment rate of traditional pond culture is low, and the problem of water eutrophication is prominent. Modern facility aquaculture has high controllability of production environment, which helps to promote the whole process reduction of input, the full utilization of waste as resources, the efficient centralized treatment of aquaculture tail water, the application of new energy and energy-saving and environment-friendly facilities and equipment, and the increase of green and high-quality aquatic product supply, and the green transformation of production mode. From the perspective of the realization of modernization of fisheries, the complete and advanced facilities are the outstanding symbol of modern fisheries. In addition to focusing on "aquaculture facilities" itself, facility aquaculture will also be equipped with automatic (precise) feeding systems, water quality monitoring systems, tail water treatment systems, etc. according to needs, which can significantly promote the intensive, standardized, mechanized, green and digital development of aquaculture, and promote the modernization of fisheries through infrastructure modernization. Pond is the main mode of aquaculture in China. However, due to the fact that the breeding density of traditional intensive pond culture exceeds the self-purification capacity of the pond water body, the excessive accumulation of leftover feed and feces can easily lead to deterioration of the pond water quality, and further cause a series of problems such as drug abuse, frequent disease outbreaks and low comprehensive benefits. In order to solve the above-mentioned problems of intensive pond culture, facility fisheries modes such as "runway fish farming", "container aquaculture", "land-based canvas barrel aquaculture", "factory aquaculture" and "pond enclosure" have emerged. The enclosure mode is concerned by breeders because of its high comprehensive benefits such as ecological, economic and social benefits due to its high solid waste discharge rate.

[0003] The patent CN216164460U disclosed by Huazhong Agricultural University discloses a floating type circulating water fish farming device, which can realize barrel-in-pool pond enclosure. A circle of water inlet holes is arranged on the upper end of the barrel body of the breeding barrel, and external water is introduced through the water inlet holes to realize water circulation in the breeding barrel. This kind of water surface type water inlet mode is easy to block the water inlet holes by algae and attached objects in the pond, and the water circulation effect in the breeding barrel is poor, the dissolved oxygen content is insufficient, and the breeding effect is difficult to guarantee.

When the breeding tank is circular, the perpendicular line R1 is the radius of the breeding tank. Projected along the height direction of the breeding tank, at least a portion of the water outlet pipe 60b is inclined relative to the radius R1 of the breeding tank. With this arrangement, the water flow from the water outlet pipe 60b impacts the liquid surface inside the breeding tank at an angle. The inclined impact of the water flow from multiple water outlet pipes 60b can cause the water inside the breeding tank to form a vortex, increasing the dissolved oxygen content of the water in the breeding tank. In one embodiment, multiple water outlet pipes 60b are arranged in parallel. With this arrangement, the water flow from each water outlet pipe 60b has the same inclination angle, which is more conducive to the formation of vortices. In another embodiment, the multiple mounting holes are positioned at the same height relative to the tank body. With this arrangement, the water flow from each water outlet pipe 60b has the same impact force, which can help form vortices. In one embodiment, for example... Figure 13 , 14 As shown, the water outlet pipe 60b extends along its length, forming an extension axis L2. Projected along the height of the aquaculture tank, the extension axis L2 is inclined relative to the vertical line R1. In one embodiment, the extension axis L2 intersects the vertical line R1, forming an angle Q1. Q1 is set as an acute angle, greater than 0 degrees and less than or equal to 90 degrees. Q1 mainly adjusts the tilt angle of the water outlet pipe 60b, which is related to the size of the vortex formed. The preferred angle for Q2 is 30-45 degrees, which facilitates the formation of a large-scale vortex in the impact water flow. In one embodiment, the inlet pipe 60a can be a flexible hose for easy adjustment of water intake. The length of the inlet pipe 60a is preferably greater than 1 meter to ensure that it reaches a deeper water layer for water intake. In one embodiment, the length of the inlet pipe 60a is greater than or equal to one-third of the length of the aquaculture tank, and its length is adapted to the size of the aquaculture tank to facilitate the selection of water from a suitable water layer. The outlet pipe 60b can be a rigid pipe to maintain a relative angle. In one embodiment, the outlet pipe 60b can also be equipped with an additional angle retainer to maintain a certain angle to stabilize the formation of the vortex water flow. Figure 15As shown, the water inlet process of the water guide 60 is that the water inlet 60a1 of the water inlet pipe 60a is below the water surface, for example, it is located at an initial water inlet liquid level A (the liquid level A is below the water surface) in an external water area of a culture barrel. After the culture tail water in the culture barrel is sucked by the suction unit 30, the water level in the culture barrel decreases, and the liquid level B is lower than the initial water inlet liquid level A. Under the action of water pressure, the water outside the culture barrel enters the water inlet pipe 60a and then flows out from the water outlet pipe 60b into the culture barrel. Since the water inlet pipe 60a is below the external water surface, the water inlet 60a will not be blocked by algae and attachments in the pond, and the water level can be kept stable and continuous, ensuring smooth water circulation. In addition, the depth of the water inlet pipe 60a in the external water can be adjusted by the lifting device 70 to select water of different water layers during the water circulation process.
