Description

Technical Field

[0001] This application relates to the technical field of seawater habitat regulation, and particularly to a flow field velocity adaptive regulation structure and device for an artificial habitat in coral aquaculture. Background Art

[0002] The coral artificial habitat system optimizes water environment parameters through artificial regulation means to create ideal growth conditions for corals. The system mainly regulates key factors such as water temperature, water flow velocity, and nutrient salt concentration, which is particularly important in the high-temperature summer season. When the seawater temperature exceeds the coral tolerance threshold, the system will start cold water injection to reduce the local water temperature and alleviate the heat stress response of corals, thereby effectively preventing the occurrence of coral bleaching.

[0003] However, due to the high cost of cold storage treatment, limited cold water volume, and limited drainage of the coral artificial habitat, it is necessary to ensure that the habitat velocity is low during the operation of the device to reduce cold water dissipation and achieve long-term preservation.

[0004] Traditional methods for controlling the seabed flow velocity include using artificial reefs (such as concrete blocks and porous rocks) to change the local water flow path to form a low-velocity area. Certain flow velocity control can be achieved by designing different reef shapes, but the changed flow velocity is only a proportional attenuation of the ambient flow velocity, and the flow velocity is not the smaller the better. When corals are in a low-velocity area for a long time, sediment deposition is likely to occur, inhibiting coral feeding and metabolism. By designing an array of retractable baffles or valves installed on the seabed, the local flow velocity can be dynamically adjusted. However, this method relies on power supply and precision equipment, has a high risk of failure, high cost, and requires multiple devices to cooperate for control, which is difficult. Summary of the Invention

[0005] To solve at least the above technical problems in the prior art, this application provides a flow field velocity adaptive regulation structure and device.

[0006] On the one hand, this application provides a flow field velocity adaptive regulation structure for regulating the flow field velocity of an artificial habitat in coral aquaculture, including a reef and a flow velocity regulation component; the reef includes holes; the flow velocity regulation component includes a mounting frame, a baffle, and a telescopic member. One end of the baffle is rotatably connected to the mounting frame, and the other end is movably connected to the mounting frame through the telescopic member. The mounting frame is connected to the reef so that the baffle is located on the hole; the baffle rotates under the action of the seabed water flow to adjust the area of the hole blocked.

[0007] In some embodiments, the reef includes a plurality of mounting surfaces, and a plurality of the holes are provided on each mounting surface; all the holes on at least one mounting surface are provided with the flow velocity regulation component.

[0008] In some embodiments, the installation frame has a set height, and a plurality of the baffle plates are arranged at intervals along the height direction of the installation frame.

[0009] In some embodiments, the flow velocity adjusting assembly further includes a connecting rod; the installation frame has a set height, a plurality of the baffle plates are arranged at intervals along the height direction of the installation frame, and the other ends of the plurality of baffle plates are connected by the connecting rod.

[0010] In some embodiments, among the plurality of baffle plates, the other end of at least one baffle plate is movably connected to the installation frame through the telescopic member.

[0011] In some embodiments, the telescopic member includes a telescopic spring; when the baffle plate is not subjected to the action force of the seabed water flow, the telescopic spring keeps a set distance between the other end of the baffle plate and the installation frame.

[0012] In some embodiments, the baffle plate moves between a contracted position and a deployed position; when the baffle plate is not subjected to the action force of the seabed water flow, the telescopic spring keeps the baffle plate in the contracted position or the deployed position.

[0013] In some embodiments, the baffle plate includes a set of long sides and a set of short sides; one long side of the baffle plate is rotatably connected to the installation frame through a first rotating shaft, the other long side is connected to a second rotating shaft, a through hole is provided at the end of the second rotating shaft, and the connecting rod is inserted into the through hole.

[0014] On the other hand, the present application further provides a flow field velocity adaptive adjustment device, including the above-mentioned flow field velocity adaptive adjustment structure.

[0015] In some embodiments, it includes a plurality of the flow field velocity adaptive adjustment structures. For the seabed water flow in the same direction, the first surface of the baffle plates of the plurality of flow field velocity adaptive adjustment structures is subjected to the action force of the seabed water flow; or the second surface of the baffle plates of the plurality of flow field velocity adaptive adjustment structures is subjected to the action force of the seabed water flow; or the first surface of the baffle plates of some of the flow field velocity adaptive adjustment structures is subjected to the action force of the seabed water flow, and the second surface of the baffle plates of another part of the flow field velocity adaptive adjustment structures is subjected to the action force of the seabed water flow.

[0016] A flow field velocity adaptive adjustment structure and device provided by the present application, when in use, place the fish reef in the environment where the flow velocity needs to be adjusted. The seabed water flow acts on the baffle plate, applying a force to the baffle plate, thereby adjusting the flipping angle of the baffle plate to adjust the area of the hole blocked by the baffle plate. For example, when it is necessary to reduce the flow field velocity, the relatively fast seabed water flow acts on the baffle plate, driving the baffle plate to approach the installation frame, increasing the blockage of the hole, thereby reducing the flow velocity. In summer when it is hot, the temperature control equipment operates to cool the seawater in the coral growth area. The low-velocity seabed water flow can reduce the convective diffusion of cold water, enabling the cold water to remain for a longer time and act on the artificial habitat for coral cultivation, which helps the coral to relieve the heat stress in extreme weather. In the technical solution of the present application, the habitat flow velocity can be automatically adjusted according to the change of the environmental flow velocity. Without external energy input, the intelligent control of the flow velocity in the habitat area is realized, which not only ensures the efficient operation of the temperature control device but also fully respects the natural physiological rhythms of organisms or plants in the speed regulation area, and has the advantages of low maintenance cost, strong environmental adaptability, and ecological friendliness.

Detailed implementation manners

[0020] To make the objectives, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0021] The embodiment of the present application provides a flow field velocity adaptive adjustment structure for adjusting the flow field velocity of an artificial habitat for coral cultivation, including an artificial reef and a flow velocity adjustment component; the artificial reef serves as a carrier for the flow velocity adjustment component and installs the flow velocity adjustment component at a specified position, that is, the seabed coral cultivation area; the flow velocity adjustment component is used to adjust the ambient flow velocity to the required habitat flow velocity.

[0022] The ambient flow velocity can be explained as: the actual flow velocity of water flow such as at the seabed or the bottom of the water; the habitat flow velocity can be explained as: the water flow velocity after the ambient flow velocity is adjusted by the flow velocity adjustment component.

[0023] The following will, with reference to the accompanying drawings, elaborate on the structures of the components of the flow field velocity adaptive adjustment structure provided by the embodiments of the present application, the connection relationships and position relationships of the components.

[0024] As Figures 1 to 4As shown in the figure, in the embodiment of the present application, the fish reef 10 includes holes 11, and the flow rate regulating component 20 is installed at the position of the holes 11. The fish reef 10 is arranged on the path of the seabed water flow, and the environmental flow rate is regulated to the habitat flow rate through the holes 11 and the flow rate regulating component 20.

[0025] For example, the fish reef 10 is in the shape of a cuboid with a hollow middle part. The fish reef 10 includes four installation surfaces, and a plurality of holes 11 are arranged on each installation surface. The plurality of holes 11 are regularly arranged to form a regular flow rate regulation. For example, along the height direction of the fish reef 10, multiple rows of holes 11 are arranged.

[0026] Among them, the flow rate regulating component 20 is installed on all the holes 11 on at least one installation surface. For example, as Figure 1 shown, the flow rate regulating component 20 is installed on all the holes 11 on one of the installation surfaces.

[0027] In the embodiment of the present application, the specific structural form of the fish reef 10 is not limited, and it can also be other shapes with holes.

[0028] Continue to refer to Figures 1 to 4 shown, in the embodiment of the present application, the flow rate regulating component 20 includes an installation frame 21, a baffle 22 and a telescopic member 23. The installation frame 21 is the installation structure of the flow rate regulating component 20, and its contour shape is the same as the shape of the hole 11.

[0029] For example, the cross-sectional shape of the hole 11 is rectangular, and the corresponding shape of the installation frame 21 is also rectangular. It includes a top end, a bottom end and two side ends, and the top end, the bottom end and the two side ends are respectively fixedly connected to the inner wall of the hole 11.

[0030] One end of the baffle 22 is rotatably connected to the installation frame 21, and the other end is movably connected to the installation frame 21 through the telescopic member 23; the baffle 22 is located inside the frame of the installation frame 21 and has a certain area. Through the cooperation between the baffle 22 and the telescopic member 23, the automatic regulation of the environmental flow rate can be realized.

[0031] For example, when the habitat flow rate is low, it is necessary to regulate the relatively high environmental flow rate to the required habitat flow rate. In the initial state, the baffle 22 has a certain throughput. As the environmental flow rate impacts the baffle 22, the baffle 22 overcomes the elastic force of the telescopic member 23, causing the baffle 22 to be in a contracted state. At this time, the baffle 22 blocks the hole 11, and the environmental flow rate is blocked and reduced.

[0032] For example, the baffle 22 is a plane or a curved surface, and it includes a set of long sides and a set of short sides. One long side of the baffle 22 is rotatably connected to the installation frame 21 through a first rotating shaft 25, and the other long side is connected to a second rotating shaft 26.

[0033] For example, a fixed end plate 27 is provided on the short side of the baffle 22. Perforations are respectively provided at the relative positions of the fixed end plate 27 and the two long sides. The end portions of the first rotating shaft 25 and the second rotating shaft 26 respectively pass through the perforations. For example, bearings are provided in the perforations. The passing-out end of the first rotating shaft 25 is rotatably connected to the mounting frame 21 through a bearing, and the passing-out end of the second rotating shaft 26 is connected to the fixed limit block 28.

[0034] For example, one end of the telescopic member 23 is connected to the mounting frame 21, and the other end is connected to the fixed end plate 27 or the fixed limit block 28.

[0035] In the embodiment of the present application, the mounting frame 21 has a set height, and a plurality of baffles 22 are arranged at intervals along the height direction of the mounting frame 21. For example, along the height direction of the mounting frame 21, the plurality of baffles 22 are evenly arranged. The setting density of the baffles 22 is determined according to the habitat flow velocity requirement. As shown in the figure, three baffles 22 are evenly arranged on the mounting frame 21, and each baffle 22 operates independently and can adjust the environmental flow velocity.

[0036] In the embodiment of the present application, the linkage adjustment of a plurality of baffles 22 can also be realized in the form of a connecting rod 24. Specifically, the mounting frame 21 has a set height, and a plurality of baffles 22 are arranged at intervals along the height direction of the mounting frame 21. The other ends of the plurality of baffles 22 are connected by a connecting rod 24. For example, a perforation is provided in the fixed limit block 28, and the connecting rod 24 is inserted into the perforation. Taking three baffles 22 as an example, the middle of the connecting rod 24 passes through the perforation of the middle fixed limit block 28, and the two ends of the connecting rod 24 respectively pass through the perforations of the fixed limit blocks 28 at the top and the bottom.

[0037] The fixed limit block 28 can slide relatively on the connecting rod 24. As the baffle 22 rotates, the acting force of the baffle acts on the connecting rod 24, and the connecting rod 24 can drive other baffles 22 to rotate by the same angle. For example, among the plurality of baffles 22, the other end of at least one baffle 22 is movably connected to the mounting frame 21 through a telescopic member 23; that is, after the connecting rod 24 structure is provided, it is not necessary to provide telescopic members 23 for all the baffles 22.

[0038] For example, limit anti-disengagement blocks 29 are respectively provided at both ends of the connecting rod 24, and telescopic members 23 are provided on the baffles 22 at the top and / or the bottom, and the end portions of the telescopic members 23 are connected to the limit anti-disengagement blocks 29.

[0039] In the embodiment of the present application, the telescopic member 23 includes a telescopic spring; when the baffle 22 is not affected by the seabed water flow, the telescopic spring keeps a set distance between the other end of the baffle 22 and the mounting frame 21. When the baffle 22 is not stressed, the telescopic spring remains in the natural telescopic state. At this time, the baffle 22 is in an unfolded state by the set distance, and the unfolding angle of the baffle 22 can be adjusted by the set distance.

[0040] When the baffle 22 is not affected by the undersea water flow, the baffle 22 may need to be presented in different positions, among which the baffle 22 moves between a retracted position and a deployed position; when the baffle 22 is not affected by the undersea water flow, the telescopic spring keeps the baffle 22 in the retracted position or the deployed position.

[0041] For example, in the retracted position, the baffle 22 can block the ambient flow velocity to reduce the flow velocity, while in the deployed position, the influence of the baffle 22 on the flow velocity is minimized, and the ambient flow velocity remains unchanged or tends to remain unchanged after passing through the baffle 22.

[0042] By setting the starting position of the baffle 22 through the telescopic spring, the adjustment requirements for different scenarios can be met. As Figure 5 shown, the flow field velocity adaptive adjustment structure in this perspective is installed forward, that is, at the first installation angle. When the baffle 22 is not affected by the undersea water flow, the baffle 22 is in the deployed position.

[0043] The baffle 22 faces the oncoming flow direction. When the ambient flow velocity is relatively large, under the action of the undersea water flow, overcoming the elastic force of the telescopic spring, the baffle 22 rotates towards the direction close to the installation frame 21, thereby forming a blockage of the hole 11, and the larger the flow velocity, the smaller the opening degree until it reaches the closed state. At this time, the habitat flow velocity is relatively low, at least 1 / 10 of the ambient flow velocity; when the ambient flow velocity is small, the ambient flow velocity has no force / tends to have no force on the baffle 22. After the undersea water flow passes through the baffle 22, the baffle 22 does not rotate or tends not to rotate. At this time, the habitat flow velocity is basically equal to the ambient flow velocity.

[0044] As Figure 6 shown, the flow field velocity adaptive adjustment structure in this perspective is installed upside down, that is, at the second installation angle. When the baffle 22 is not affected by the undersea water flow, the baffle 22 is in the retracted position.

[0045] The baffle 22 faces the oncoming flow direction. When the ambient flow velocity is relatively large, under the action of the undersea water flow, the baffle 22 is rotated to a larger opening degree, and the larger the flow velocity, the larger the opening degree until it rotates to the deployed position. At this time, the habitat flow velocity is basically equal to the ambient flow velocity; when the flow velocity is very small, the ambient flow velocity has no force / tends to have no force on the baffle 22, and the baffle 22 is in the retracted position. The baffle 22 further blocks the undersea water flow, making the habitat flow velocity even smaller.

[0046] As Figure 7 shown, after the ambient flow velocity passes through the flow field velocity adaptive adjustment device, the flow velocity is effectively changed, that is, the ambient flow velocity is reduced; as Figure 8 shown, after the ambient flow velocity passes through the flow field velocity adaptive adjustment device, the ambient flow velocity remains unchanged, making the ambient flow velocity and the habitat flow velocity basically the same.

[0047] An embodiment of the present application provides a flow field velocity adaptive adjustment device, including the above-mentioned flow field velocity adaptive adjustment structure, and controls the flow field velocity within a certain range of water area through the arrayed flow field velocity adaptive adjustment structure.

[0048] For example, the first surface of the baffle 22 of multiple flow field velocity adaptive adjustment structures is affected by the undersea water flow force, that is, the flow field velocity adaptive adjustment structure is installed forward; or the second surface of the baffle 22 of multiple flow field velocity adaptive adjustment structures is affected by the undersea water flow force, that is, the flow field velocity adaptive adjustment structure is installed upside down; or the first surface of the baffle 22 of some flow field velocity adaptive adjustment structures is affected by the undersea water flow force, and the second surface of the baffle 22 of another part of the flow field velocity adaptive adjustment structures is affected by the undersea water flow force, that is, multiple flow field velocity adaptive adjustment structures are installed forward and upside down in parallel.

[0049] Taking the flow field velocity adjustment of the artificial habitat for coral breeding as an example. By setting multiple flow field velocity adaptive adjustment structures to enclose a certain range of water area, the corals are arranged within the enclosed water area. Among them, some flow field velocity adaptive adjustment structures are installed forward, and some flow field velocity adaptive adjustment structures are installed upside down.

[0050] As Figure 9 shown, assuming that the morning tide flow direction is as shown by the solid arrow in the figure, when the undersea water flow passes through the flow field velocity adaptive adjustment structure 1 installed forward, the flow velocity will become smaller, and when the undersea water flow passes through the flow field velocity adaptive adjustment structure 2 installed upside down, the flow velocity will become even smaller. If the abnormal value of the habitat temperature is large at this time, start the habitat temperature control device, and the habitat temperature control device will reduce the habitat temperature within the area. Since the habitat flow velocity is small, the loss of the cooled undersea water flow is reduced, enabling the habitat temperature control device to work efficiently; that is, avoiding the large flow velocity and increasing the working intensity of the habitat temperature control device.

[0051] As Figure 10 shown, assuming that the afternoon tide flow direction changes, as shown by the solid arrow in the figure, the undersea water flow passes through the flow field velocity adaptive adjustment structure 2 installed upside down and then through the flow field velocity adaptive adjustment structure 1 installed forward. The change in the environmental flow velocity is close to a Gaussian distribution, and it will experience a process from small to large and then from large to small, and the corresponding habitat flow velocity will also experience corresponding changes. If the abnormal value of the habitat temperature is large at this time, the habitat temperature control device will work when the environmental flow velocity is small. At this time, the habitat flow velocity is very small, which can enable the habitat temperature control device to work efficiently; when the environmental flow velocity is large, the habitat flow velocity will also be large and basically equal to the environmental flow velocity. At this time, the habitat temperature control device does not work, and the corals can carry out sufficient feeding, transporting metabolic wastes, and optimizing the bottom substrate environment.

[0052] In the embodiments of the present application, the arrangement of multiple flow field velocity adaptive adjustment structures is not limited to this, and the arrangement method needs to be changed according to different scenarios. However, in each usage scenario, there are mainly three forms, namely, the flow field velocity adaptive adjustment structure 1 installed all in the forward direction, the flow field velocity adaptive adjustment structure 2 installed all in the inverted direction, or the flow field velocity adaptive adjustment structure 1 installed partially in the forward direction and the flow field velocity adaptive adjustment structure 2 installed partially in the inverted direction.

[0053] For example, referring to factors such as tidal type, tidal current change frequency, heat anomaly, etc., determine the type selection and arrangement method of multiple flow field velocity adaptive adjustment structures.

[0054] For example, judge the tidal type (the number of ebb and flow of the tidal current within a day), determine whether the water area is semi-diurnal tide, diurnal tide, or mixed tide, and then judge the change direction of the tidal current flow (at the same location, the tidal type and tidal current direction may be different in different months and times) and the duration of heat anomaly.

[0055] Obtain the changes of the above data in a year. Among them, the data should include the data information of each time period of each day, determine the data with the largest proportion of summer heat anomaly, that is, the duration of summer heat anomaly. Select different arrangement combinations, compare the adjustment effects, and combine with engineering requirements to select the required arrangement method and arrangement orientation.

[0056] For example, as shown in the following table:

[0057] The installation method in the present application is not limited to the above table, and more combination methods can also be set according to the designed installation scenario. For example, combination methods such as alternating installation and nested annular array installation can be adopted.

[0058] A flow field velocity adaptive adjustment structure and device provided by the present application, when in use, place the fish reef 10 in the environment where the flow velocity needs to be adjusted. The seabed water flow acts on the baffle 22, applying a force to the baffle 22, thereby adjusting the flipping angle of the baffle 22 to adjust the area of the hole 11 blocked by the baffle 22. For example, when it is necessary to lower the flow field velocity, the seabed water flow with a larger flow velocity acts on the baffle 22, driving the baffle 22 to approach the installation frame 21, increasing the blocking of the hole 11, thereby reducing the flow velocity. In summer when it is hot, the temperature control device operates to cool the seawater in the coral growth area. The low-velocity seabed water flow can reduce the convective diffusion of cold water, enabling the cold water to remain for a longer time and act on the artificial habitat for coral farming, which helps the coral to relieve the heat stress in extreme weather. In the technical solution of the present application, the flow velocity of the habitat can be automatically adjusted according to the change of the environmental flow velocity. Without external energy input, the intelligent control of the flow velocity in the habitat area can be realized, which not only ensures the efficient operation of the temperature control device but also fully respects the natural physiological rhythms of organisms or plants in the speed regulation area, and has the advantages of low maintenance cost, strong environmental adaptability, and ecological friendliness.
