Description

Technical Field

[0001] This utility model relates to the field of fish farming, and in particular to a high-flow-rate aquaculture tank device. Background Technology

[0002] The construction of water conservancy and hydropower projects has had a negative impact on fishery resources. Artificial propagation and release is an important means to compensate for the decline in fish resources caused by the development of water conservancy and hydropower projects, ensure the continuation of rare and endangered fish populations, and supplement economic fish resources. At present, propagation stations generally construct water storage and sedimentation ponds, fry rearing workshops, broodstock rearing ponds, fingerling rearing ponds, live feed rearing ponds (which also serve as aquaculture runoff treatment ponds), and supporting facilities. Currently, the flow velocities provided by various types of aquaculture ponds in propagation stations are generally below 0.2 m / s, which is relatively slow. Fish that are adapted to high-velocity flowing water environments are difficult to cultivate or find it difficult to adapt to natural river habitats after release.

[0003] The genus *Sterculia*, including the *Sterculia* var. *qingshi* and *Sterculia* var. *huangshi*, are benthic fish that attach themselves to pebbles and other objects in flowing water. They typically inhabit mountain rivers with gravelly riverbeds and rapid currents, moving by clinging to the rocks belly-to-belly or in crevices. They usually spawn on rocky riverbanks in fast-flowing water. Therefore, both their living and spawning activities prefer water with a certain flow rate and a gravelly bottom. Other fish species, such as the Sichuan-Shaanxi taimen, *Schizothorax bream*, *Schizothorax bream*, perch, and loach, also prefer fast-flowing environments. However, current fish breeding facilities mainly consist of circular or square ponds with small water inflow rates, large pond volumes, and virtually no flow. These conditions are unfavorable for breeding *Sterculia* and other aquatic organisms adapted to high-flow-rate environments. Preliminary assessments suggest that the breeding facilities do not meet the habits of *Sterculia*, which is one of the key factors preventing a breakthrough in artificial breeding techniques for this genus. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a high-flow-rate aquaculture tank device.

[0005] The specific technical solution is as follows:

[0006] A high-flow-rate aquaculture tank device includes: an elevated water tank, a high-flow-rate aquaculture tank, a low-level water tank, a circulating lift pump, and circulating pipes; the bottom elevation of the elevated water tank is higher than that of the low-level water tank; the high-flow-rate aquaculture tank is meandering, with its two ends connected to the elevated water tank and the low-level water tank respectively; the bottom of the high-flow-rate aquaculture tank is connected to the bottom of the low-level water tank via a ramp; the bottom slope of the high-flow-rate aquaculture tank has different gradients.

[0007] The low-level water tank is enclosed by a partition wall, part of which is replaced by a fish barrier grille. The area inside the partition wall is a separate zone, and the elevation of the bottom surface of the separate zone is lower than the elevation of the bottom surface of the low-level water tank outside the partition wall. The circulating lift pump is arranged in the separate zone. One end of the circulating pipe is connected to the output end of the circulating lift pump, and the other end is connected to the high-level water tank, which is used to transport water from the low-level water tank to the high-level water tank.

[0008] Furthermore, a through hole is opened at the bottom of the elevated water tank, which is connected to the end of the high-flow-rate aquaculture tank through a pipe. A flow regulating valve is installed in the pipe to control the input flow rate of the high-flow-rate aquaculture tank.

[0010] Furthermore, the high-flow-rate aquaculture tank has a deep pool section at the bend, with fine-grained sand at the bottom; and a shallow beach section at the relatively straight part, with coarse-grained sand at the bottom.

[0011] Furthermore, the volume of the low-level water tank is greater than the sum of the volumes of the high-level water tank and the high-flow-rate aquaculture tank.

[0012] Furthermore, a water supply pipe is arranged on the upper end of the side wall of the high-level water tank, and its opening and closing are controlled by a water supply pipe control valve; an overflow pipe is arranged on the side wall corresponding to the highest liquid level of the low-level water tank; an venting pipe is arranged on the lower end or bottom of the side wall of the low-level water tank, and its opening and closing are controlled by a venting pipe control valve.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments. The purpose and effects of the present invention will become clearer as a result. Further detailed description of the present invention will be provided below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0026] Example 1

[0027] like Figure 1 , Figure 2As shown, a high-flow-rate aquaculture tank device includes: a high-level water tank 1, a low-level water tank 2, a high-flow-rate aquaculture tank 3, an inclined ramp 4, a circulation lift pump 5, a circulation pipe 6, a flow regulating valve 7, a fish barrier 8, a water quality monitor 9, a low-level water tank level gauge 10, a high-level water tank level gauge 11, a flow meter 12, a camera 13, a partition wall 14, a deep pool section 15, a shallow beach section 16, a water supply pipe 17, a water supply pipe control valve 18, an overflow pipe 19, a drain pipe 20, and a drain pipe control valve 21.

[0028] A high-level water tank 1, a meandering high-flow-rate aquaculture trough 3 (in this embodiment, the high-flow-rate aquaculture trough 3 is curved and without turning), and a low-level water tank 2 are arranged sequentially. The bottom elevation of the high-level water tank 1 is higher than the highest water surface elevation of the low-level water tank 2. Water in the high-level water tank 1 flows into the low-level water tank 2 through the high-flow-rate aquaculture trough 3. The low-level water tank 2 also serves as an aquaculture pond, providing a low-flow-rate habitat. The high-flow-rate aquaculture trough 3 creates habitats with different flow rates by setting different bottom slopes. A through hole is opened at the bottom of the high-level water tank 1, which is connected to one end of the high-flow-rate aquaculture trough 3 through a pipe. A flow regulating valve 7 is installed inside the pipe to regulate the flow rate entering the high-flow-rate aquaculture trough 3, thereby adjusting the water level inside the high-flow-rate aquaculture trough 3. The other end of the high-flow-rate aquaculture tank 3 is connected to the low-level water tank 2. A ramp 4 is provided in the low-level water tank 2 from this connection point to facilitate the movement of aquatic organisms cultured in the low-level water tank 2 into the high-flow-rate aquaculture tank 3. In this embodiment, a flow velocity exceeding 0.6 m / s is defined as a high flow velocity.

[0029] A partition wall 14 is installed on one side of the low-level pool 2, forming a separate area. The bottom elevation of this separate area is 0.5m to 1m lower than the bottom elevation of the pool outside the partition wall 14. A portion of the partition wall 14 is replaced with a fish barrier 8, connecting the pool outside the partition wall 14 with the separate area inside. A circulation pump 5 is installed within the separate area. One end of the circulation pipe 6 is connected to the output end of the circulation pump 5, and the other end is connected to the high-level pool 1. When the circulation pump 5 is turned on, water is lifted from the low-level pool 2 to the high-level pool 1, achieving circulation. The partition wall 14 serves to separate the pool areas. Although the fish barrier 8 allows water flow, the partition wall 14 still has a certain control over the speed and direction of the water flow, which helps maintain the water flow conditions required by the circulation pump 5 in the separated area. The fish barrier 8 prevents aquatic organisms and large particles (including fish feces, uneaten food, etc.) from entering the circulation pump 5, thereby protecting the equipment from blockage and damage and maintaining its normal operation.

[0030] The bottom slope of the high-velocity flow-through aquaculture tank 3 ranges from 0.2% to 3%. Several high-velocity flow-through aquaculture tanks 3 can be set up, and different high-velocity flow-through aquaculture tanks 3 can have different degrees of curvature and / or bottom slope and / or substrate, thereby creating habitats with different flow velocities and / or substrates. Similarly, different bottom slopes and / or substrates can be set within a single high-velocity flow-through aquaculture tank 3, thus creating habitats with different flow velocities and / or substrates within that single high-velocity flow-through aquaculture tank 3. The specific bottom slope setting for the high-velocity flow-through aquaculture tank 3 is determined based on the actual situation. The water flow velocity can be calculated using Manning's formula. The calculation is performed, where v represents the flow velocity, R represents the hydraulic radius, μ represents the Manning coefficient (roughness coefficient), and i represents the bottom slope. As an example, the high-velocity flowing water aquaculture tank 3 has a trapezoidal cross-section with a bottom width of 1.5m, a water depth of 0.5m, and a top water surface width of 2.5m. With a roughness coefficient of 0.023, the calculated flow velocity is approximately 0.63 m / s when the bottom slope is 0.2%; approximately 1.00 m / s when the bottom slope is 0.5%; approximately 1.41 m / s when the slope is 1.0%; approximately 1.99 m / s when the slope is 2.0%; and approximately 2.44 m / s when the slope is 3.0%. Furthermore, the flow field conditions (including parameters such as flow velocity and water depth) can also be determined using methods such as numerical simulation.

[0031] Furthermore, gravel is embedded in the bottom of the high-flow-rate aquaculture tank 3, and the specific setting can be adjusted according to the required roughness. Alternatively, obstacles that do not obstruct water flow can be created, similar to those used in natural fishways; these obstacles can be constructed using pebbles or simply piled up. Greenery can be planted on both sides of the high-flow-rate aquaculture tank 3 to create a landscaping effect and better simulate a natural environment.

[0032] Furthermore, the high-flow-rate aquaculture tank 3 is equipped with a deep pool section 15 and a shallow beach section 16, mimicking a natural river habitat. The deep pool section 15 is generally located at a bend in the high-flow-rate aquaculture tank 3, and its cross-section is as follows: Figure 3 As shown, the overall water depth is relatively large, and the bottom is covered with fine-grained sand. Small wooden blocks can also be placed to simulate a natural river. The shallow section 16 is generally located in a relatively straight area, and its cross-section is as follows... Figure 4 As shown, the bottom elevation is relatively uniform, the overall depth is shallow, the flow velocity is relatively fast, and the bottom is covered with coarse sand.

[0033] Furthermore, the slope of the ramp 4 is 1:n, where n can be determined according to the size of the site, the habits of the fish, etc. The ramp 4 can connect the bottom of the high-flow-rate aquaculture tank 3 to the bottom of the low-level pool 2. Taking the rock loach genus as an example, this structure can adapt to the habit of the rock loach genus to move with its abdomen close to the rock, making it convenient for the rock loach genus fish to enter the high-flow-rate aquaculture tank 3 from the low-level pool 2.

[0034] Furthermore, the volume of the low-level water tank 2 should be greater than the sum of the volumes of the high-level water tank 1 and the high-flow-rate aquaculture tank 3, and ensure that after all the water enters the low-level water tank 2, the highest water level is greater than 0.3m from the top of the tank, so as to prevent overflow after all the water enters the low-level water tank 2 in the event of damage to the circulating lift pump 5 or the flow regulating valve 7.

[0035] Furthermore, a through hole is opened at the upper end of the side wall of the high-level water tank 1 to accommodate a water supply pipe 17. A water supply pipe control valve 18 is installed inside the water supply pipe 17. The water supply pipe control valve 18 can be opened and closed under the control of the control terminal, thereby controlling whether water is supplied to the entire aquaculture tank. A through hole is opened on the side wall of the low-level water tank 2 to accommodate an overflow pipe 19. The position of the through hole corresponds to the maximum liquid level requirement of the low-level water tank 2. The overflow pipe 19 is always kept open. When the water in the low-level water tank 2 exceeds the maximum liquid level, the excess water is automatically discharged through the overflow pipe 19. A through hole is opened at the lower end of the side wall or bottom of the low-level water tank 2 to accommodate a vent pipe 20. A vent pipe control valve 21 is installed inside the vent pipe 20, which can be opened and closed under the control of the control terminal, thereby controlling whether drainage is required.

[0036] A high-level water tank 1 is equipped with a high-level water tank level gauge 11 to detect the water level in high-level water tank 1 and transmit the data to the control terminal; a low-level water tank 2 is equipped with a low-level water tank level gauge 10 to detect the water level in low-level water tank 2 and transmit the data to the control terminal. The control terminal comprehensively analyzes the water level data of the two water tanks to determine whether water replenishment is needed. A water quality monitor 9 is also installed in low-level water tank 2, whose main monitoring indicators include pH, water temperature, dissolved oxygen, nitrite, etc. The water quality data obtained by the water quality monitor 9 is transmitted to the control terminal. If the monitored values ​​are abnormal, the control terminal will remind the user to take action to ensure that the device can meet the survival needs of aquatic organisms. Flow meters 12 are installed at different bottom slope positions inside the high-flow-rate aquaculture tank 3 to monitor the flow velocity at different locations in real time. Cameras 13 are installed above different positions in the high-flow-rate aquaculture tank 3 to observe the swimming position and activity of fish.

[0037] Example 2

[0038] When a high-flow-rate aquaculture tank device needs to be installed indoors, the overall space is limited. The non-rotating arrangement of the high-flow-rate aquaculture tank 3 in Embodiment 1 cannot be accommodated; therefore, this embodiment is proposed. This embodiment of the high-flow-rate aquaculture tank device also includes a high-level water tank 1, a low-level water tank 2, and a high-flow-rate aquaculture tank 3. One end of the inlet pipe of the high-flow-rate aquaculture tank 3 is connected to the high-level water tank 1, and one end of the outlet pipe is connected to the low-level water tank 2. Figure 5 and Figure 6As shown, the high-flow-rate aquaculture tank 3 is S-shaped, and the slope and / or substrate before and after the rotation can be set differently to create habitats with different flow rates; the rest of the structure is the same as in Embodiment 1. The S-shaped rotation design greatly reduces the length required for the device.

[0039] Furthermore, if the indoor space is insufficient to support the arrangement of two pools, only the lower pool 2 can be retained. One end of the circulation pipe 6 is connected to the circulation lift pump 5, and the other end is directly connected to the inlet pipe of the high-flow-rate aquaculture tank 3 (i.e. the higher elevation end), further reducing the space occupied by the device.

[0040] It will be understood by those skilled in the art that the above descriptions are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. All modifications and equivalent substitutions made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
