Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture facilities technology, specifically to a new type of aquaculture pond. Background Technology
[0002] Currently, recirculating aquaculture systems (RAS) are rapidly being adopted in the aquaculture industry due to their high efficiency, water conservation, environmental friendliness, and eco-friendliness. RAS is a new aquaculture model that utilizes a recirculating water treatment system to purify and circulate the aquaculture water. This allows excess feed, fish and shrimp excrement, and other organic matter to be promptly separated from the water, preventing them from decomposing into toxic substances such as ammonia nitrogen and nitrite.
[0003] One of the core elements of a recirculating aquaculture system (RAS) is the design of the aquaculture pond itself, which directly affects water quality maintenance, the health of the cultured organisms, and the efficiency of operation and management. Currently, most mainstream aquaculture ponds have a flat or shallow conical bottom structure. The theoretical basis for this is that fish feces, uneaten feed, and other solid waste have a density greater than water and will naturally settle, sliding down to the lowest point of the pond bottom under gravity, and finally being discharged through the drain outlet located at the lowest point of the pond. However, in actual aquaculture, the movement of fish and the disturbance of the incoming water flow can create turbulence in the water, easily stirring up the settled impurities and preventing them from reaching the central drain outlet smoothly. Especially in larger aquaculture ponds, the settling path from the edge to the center of the pond is long, greatly increasing the possibility of impurities becoming suspended and dispersed. At the same time, in order to enhance the collection effect, many traditional fish ponds create a rotating water flow by tangentially introducing water into the pond wall, using centrifugal force to throw impurities towards the edge of the pond. However, this creates a fundamental contradiction with the "low in the middle" design of the pool bottom: centrifugal force aims to throw impurities to the surrounding pool walls, while gravity requires impurities to slide to the center bottom. This conflict of forces causes a large number of impurities to be suspended or randomly deposited in the annular zone between the pool walls and the center of the pool, forming a "circulating sedimentation zone" that cannot be effectively collected and ultimately becomes a long-term source of water pollution.
[0004] Therefore, traditional central sewage design makes it difficult to achieve continuous and thorough sewage cleaning. In order to discharge concentrated sewage, it is necessary to rely on a high-flow, high-power "forced discharge" mode to periodically discharge large amounts of pool water. This not only causes a huge waste of water resources and energy, but also greatly impacts the downstream water treatment system. Summary of the Invention
[0005] The purpose of this invention is to provide a novel aquaculture pond that, by setting an inverted conical bottom and a dedicated guide channel, actively throws impurities toward the pond edge and transports them to the filtration point using the centrifugal force of the rotating water flow. This ensures that the water flow dynamics and the impurity transport path are coordinated, thereby achieving efficient, directional, and automatic collection and discharge of impurities.
[0006] The technical solution adopted in this utility model is as follows: A novel aquaculture pond includes a pond body with a central pipe at its axial center. An inlet pipe is installed at the central pipe's axial center. A water guide plate is positioned near the top of the central pipe, sealing the upper end of the central pipe. The inlet pipe passes through the water guide plate and has an open top. Two water guide strips are arranged on the water guide plate, forming a Z-shaped outlet channel with the side wall of the central pipe. The two ends of the outlet channel form outlets, which are symmetrically positioned with respect to the inlet pipe. A through hole is provided at the corresponding water outlet position to form a water outlet. The bottom of the pool body is a centrally raised conical structure. Two water push grooves are opened at the bottom of the pool body. The water push grooves are located below the water outlet. Two water push pipes are provided on the central pipe. The open end of the water push pipe is located at the upper end of the water push groove and faces the water push groove. The rear end of the water push pipe is connected to the water inlet pipe. Two side boxes are provided on the side wall of the pool body. The side boxes have openings facing the water flow direction. The lower end of the water push groove extends to the opening end of the side box.
[0007] Furthermore, the top of the central tube is slightly lower than the side wall of the pool, and the central tube is a hollow tubular structure.
[0008] Furthermore, the water guide strip is in the shape of a figure 7, with two water guide strips respectively arranged on both sides of the water inlet pipe and arranged symmetrically at the center.
[0009] Furthermore, the conical structure at the bottom of the pool has a raised angle of 10-15 degrees, and the conical bottom slopes outward from the central tube.
[0010] Furthermore, the front end of the water pusher channel has a downward sloping surface, and the bottom of the water pusher channel has a square structure.
[0011] Furthermore, a mounting plate with a window is installed on the opening of the side box, and a filter screen is provided on the back of the mounting plate, with a cleaning mechanism provided on the filter screen.
[0012] Furthermore, the side box is equipped with a drain pipe and a drain pipe. The drain pipe is connected to other purification equipment through a pipe, and the drain pipe is connected to the municipal sewage network through a pipe. Both the drain pipe and the drain pipe are equipped with valves.
[0013] Furthermore, the pool body is also connected to a high-oxygen water inlet pipe, which penetrates the bottom of the pool body and extends into the central pipe. A baffle is installed inside the central pipe, and a closed stagnant space is formed between the baffle and the water guide plate. The open end of the high-oxygen water inlet pipe enters the stagnant space. A ring of high-oxygen water outlet holes is opened on the side wall of the central pipe located in the stagnant space area.
[0014] Compared with the prior art, the beneficial effects obtained by this utility model are as follows: The novel aquaculture pond provided by this utility model transforms the traditional gravity-based impurity removal mode into a centrifugal-based impurity removal mode by combining an inverted conical pond bottom with a "water pusher trough + water pusher pipe". Impurities flow along the inclined surface into the water pusher trough and are efficiently thrown to the edge of the pond by the rotating water flow. They are then directionally and forcibly transported to the side box, achieving active sludge collection with no dead corners on the entire pond bottom. This fundamentally solves the industry problem of "circulating sedimentation zone" and significantly improves treatment efficiency. At the same time, an independent high-oxygen water pipe is set up. The design of shearing and mixing the water outlet on the side wall with the main water flow outside the central pipe supports the near-ultra-high dissolved oxygen efficiency. Moreover, it can accurately increase oxygen on demand, making management flexible and significantly reducing oxygen usage costs. Attached Figure Description

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figure 1 , Figure 2As shown, a novel aquaculture pond includes a pond body 1, which is directly placed on the ground or installed on the ground via a frame. The pond body 1 is a facility for raising fish, shrimp, or shellfish. The pond body 1 has a circular structure with a diameter of 5-8 meters being preferred. A fish pond observation window 11 is provided on the side wall of the pond body 1 for easy observation of the pond's interior. A central pipe 2 is located at the axial position of the pond body 1, with its top slightly lower than the side wall of the pond body 1. The central pipe 2 is a hollow tubular structure. A water inlet pipe 21 is installed at the axial position of the central pipe 2. The upper end of the water inlet pipe 21 is open and lower than the top of the central pipe 2. The lower end of the water inlet pipe 21 passes through the side wall of the pond body 1 and connects to an external pipe, allowing fresh water to enter the pond body 1 through the water inlet pipe 21. A water guide plate 2 is located near the top of the central pipe 2. 2. The water guide plate 22 seals the upper end of the central pipe 2. The inlet pipe 21 passes through the water guide plate 22 and has an opening at the upper end. The water guide plate 22 is provided with two water guide strips 23, which are in the shape of a "7". The two water guide strips 23 are respectively set on both sides of the inlet pipe 21 and are centrally symmetrical. The water guide strips 23 and the side wall of the central pipe 2 together form a Z-shaped water outlet. The two ends of the water outlet form water outlets. The two water outlets are centrally symmetrical with the inlet pipe 21. The central pipe 2 is provided with a through hole corresponding to the water outlet position to form a water outlet 211. The water from the inlet pipe 21 flows out from the two water outlets 211, thereby forming a tangential thrust, driving the entire pool water to rotate around the central pipe. According to this structure, the aquaculture pool does not need to be equipped with a separate water outlet nozzle, which can effectively save on operating costs.
[0018] like Figure 3 As shown, the bottom of the pool body 1 is a centrally raised conical structure, preferably a conical or hemispherical raised shape, with a raised angle of 10-15 degrees. The bottom of the cone slopes outward from the central tube 2. Two water-pushing channels 24 are opened at the bottom of the pool body 1. The water-pushing channels 24 are used to collect and remove solid sediments, such as fish feces, feed residue, and large particles of impurities such as silt. Figure 5As shown, the water pusher trough 24 has a downward sloping surface at its front end. This slope facilitates the sliding of impurities towards the bottom of the water pusher trough 24. The bottom of the water pusher trough 24 has a square structure, which makes it difficult for impurities entering the water pusher trough 24 to be carried out by the water flow. The sloping surface also forms a vertical blocking surface at the rear end of the water pusher trough 24, which can effectively prevent impurities from being carried out of the water pusher trough 24, further improving the efficiency of impurity collection. The water pusher trough 24 is located below the water outlet 211. Due to the rotating water flow sprayed from the Z-shaped water outlet 211, its kinetic energy will directly act on the bottom area of the pool directly below during the downward diffusion process. This means that the area with the most concentrated energy is specifically used to drive the water flow in the water pusher trough, which provides a continuous and strong tangential driving force for the water pusher trough 24, ensuring that impurities flowing into the trough can be quickly and reliably transported to the edge of the pool body 1 along the tangential direction of the pool wall, effectively preventing impurities from being deposited or retained in the water pusher trough. Two water pusher pipes 25 are provided on the central pipe 2. The open end of the water pusher pipe 25 is located at the upper end of the water pusher trough 24 and faces the water pusher trough 24. The rear end of the water pusher pipe 25 is connected to the water inlet pipe 21. The water sprayed out by the water pusher pipe 25 can provide auxiliary water flow into the water pusher trough 24, enhance the driving force for impurities to move downward and prevent sedimentation in the trough.
[0019] like Figure 2 , Figure 3 As shown, two side boxes 3 are symmetrically arranged on the side wall of the pool body 1. The side boxes 3 are roughly square in shape and have openings facing the water flow direction. A mounting plate 31 with a window is installed on the opening. A filter screen 32 is installed on the back of the mounting plate 31. The filter screen 32 is used to filter impurities in the water. Preferably, a cleaning mechanism 33 is provided on the filter screen 32 to periodically clean the filter screen 32 and prevent clogging. The lower end of the water pusher trough 24 extends to the opening of the side box 3, allowing impurities in the water pusher trough 24 to flow into the side box 3 along with the water flow. The tank 1 is equipped with a drain pipe 34 and an empty pipe 35. The drain pipe 34 is connected to other purification equipment through a pipe. The water in the side box 3 is discharged through the drain pipe 34. The empty pipe 35 is used to empty the water in the tank 1. If the aquatic products in the tank 1 have viruses and the water needs to be changed, the empty pipe 35 can be opened to drain all the water in the tank 1. The empty pipe 35 is connected to the municipal sewage network through a pipe. Preferably, both the drain pipe 34 and the empty pipe 35 are equipped with valves. The valve on the empty pipe 35 is normally closed, and the valve on the drain pipe 34 can control the water level in the tank 1 by controlling the degree of opening and closing.
[0020] like Figure 3 , Figure 4As shown, a high-oxygen water inlet pipe 4 is also connected to the pool body 1. The high-oxygen water inlet pipe 4 is used to inject oxygen-rich water into the pool body 1 to ensure that the water in the pool body 1 has sufficient oxygen content. The high-oxygen water inlet pipe 4 penetrates the bottom of the pool body 1 and extends into the central pipe 2. A baffle 41 is installed inside the central pipe 2. The baffle 41 and the water guide plate 22 form a closed stagnant space. The open end of the high-oxygen water inlet pipe 4 enters into this stagnant space. A ring of high-oxygen water outlet holes 42 is opened on the side wall of the central pipe 2 in the stagnant space area. The oxygen-rich water enters the stagnant space of the central pipe 2 through the high-oxygen water inlet pipe 4. The oxygenated water then enters the pool 1 through the high-oxygen water outlet 42. The surrounding high-oxygen water outlet 42 ensures that the high-oxygen water is injected into the water flow in the pool 1 evenly and radially from 360 degrees. The oxygen-enriched water is evenly diffused throughout the entire pool by the rotating flow, ensuring the uniformity of dissolved oxygen in the water and completely eliminating low-oxygen dead zones in the corner areas. Since the high-oxygen water inlet pipe is designed completely independently, the administrator can independently adjust the oxygen supply according to real-time dissolved oxygen monitoring data or the breeding cycle without changing the main water inlet flow rate and flow pattern. This realizes the transformation from "extensive oxygen supply" to "precise oxygen supply", significantly saving oxygen costs and flexibly responding to sudden oxygen consumption events.
[0021] The working principle of this utility model is as follows: Fresh water injected through inlet pipe 21 is ejected through the Z-shaped outlet at the top of central pipe 2, creating tangential thrust that drives the entire pool water to rotate around central pipe 2. During this process, the conical pool bottom, higher in the center and lower around the edges, works in conjunction with the centrifugal force of rotation, causing fish feces, uneaten food, and other impurities to slide down the slope of the pool bottom into the water pusher trough 24 at the bottom of the ring cloth. The rotating water flow and the pool bottom structure work together to form a flow field that gathers impurities from suspension to the water pusher trough 24. In this centripetal collection flow field from the center of the pool to the edge, the high-concentration impurity-containing water collected in the water pusher trough is transported by its own gravity and the water flow ejected from water pusher pipe 25. As water passes through the filter screen on the side box 3, impurities are trapped outside the screen, and clean water enters the side box 3 and is discharged through the outlet pipe. The trapped impurities can be removed periodically by the side box cleaning mechanism. At the same time, oxygen-rich water enters the stagnant space of the central pipe 2 through the high-oxygen water inlet pipe 4, and then enters the pool body 1 through the high-oxygen water outlet hole 42. The surrounding high-oxygen water outlet hole 42 allows the oxygen-rich water to be injected into the water flow in the pool body 1 evenly and radially from 360 degrees. The oxygen-rich water is evenly diffused to the entire pool body with the rotating flow, ensuring the oxygen content of the water in the entire pool body 1 and improving the breeding efficiency.
[0022] The novel aquaculture pond provided by this utility model transforms the traditional gravity-based impurity removal mode into a centrifugal-based impurity removal mode by setting an inverted conical pond bottom and combining a "water pusher trough + water pusher pipe". Impurities flow along the inclined surface into the water pusher trough and are efficiently thrown to the edge of the pond by the rotating water flow. Then, they are directionally and forcibly transported to the side box, realizing active sludge collection without dead corners on the entire pond bottom. This fundamentally solves the industry problem of "circulating sedimentation zone" and greatly improves treatment efficiency. At the same time, an independent high-oxygen water pipe is set up. The design of shearing and mixing with the main water flow outside the central pipe through the side wall outlet holes achieves near-maximum dissolved oxygen efficiency. Moreover, it can accurately increase oxygen on demand, making management flexible and significantly reducing oxygen usage costs.

Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
