Description

Technical Field

[0001] The present disclosure relates to the technical field of marine engineering equipment, and in particular to a water supply device for creating an artificial coral reef habitat. Background Art

[0002] Artificial coral reef habitats are created through artificial drainage to create an environment with temperature, liquid and nutrients suitable for coral growth and reproduction. Especially in extremely high temperature weather in summer, artificial discharge of cold water is needed to relieve coral heat stress and prevent bleaching.

[0003] Coral growth requires a water environment with a stable flow rate and no drastic fluctuations. Due to the high cost of cold storage treatment, limited cold water supply, and limited drainage capacity for artificial coral reef habitats, a high discharge rate accelerates cold water consumption and exacerbates the mixing of hot and cold water. This fails to ensure the long-term maintenance of cold energy and accelerates the mixing and dissipation of cold water into the rising and falling environment, which is also incompatible with coral growth requirements. Furthermore, since the seabed and water storage tanks contain impurities such as sand, gravel, and shell fragments, to prevent these from affecting the long-term operation of the device, the discharge port needs to have filtering and anti-clogging functions to serve as a water supply device.

[0004] Traditional submarine water supply devices generally use static filtration structures to filter out blockages. Solid impurities are intercepted by setting a fixed filter at the water inlet. However, after filtration, the blockage is deposited on one end of the filter and cannot be processed. Pollutants accumulate on the water-facing surface of the filter to form a dense layer, resulting in a reduction in the cross-sectional area of the liquid channel and an increase in the internal pressure of the device. This not only reduces drainage efficiency, but also causes the risk of structural deformation and affects coral growth. Summary of the Invention

Detailed implementation manners

[0047] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0048] The embodiments of the present disclosure can solve the problem of coral reef heat stress bleaching, as Figure 8 shown, cold water is prepared by the refrigeration device 7, the cold water is arranged in the water storage device 8, and the water storage device 8 is connected to the water supply device 100 for creating an artificial coral reef habitat through the drain pipe 1, so that the cold water in the water storage device can be transported to the artificial coral reef habitat. The water supply device 100 discharges cold water to relieve the heat stress of the coral 9. Combining Figure 2 , Figure 3 and Figure 4As shown, the embodiment of the present disclosure provides a water supply device for creating an artificial habitat for coral reefs, and is used for regulating the water supply of an artificial habitat for coral cultivation. The water supply device includes a shell 2, a filter assembly 3, a protective cover 4, a first elastic member 51, and a second elastic member 52. The shell 2 is formed with a first cavity 23, and the shell 2 is provided with a liquid inlet 211, a first discharge port 221, and a second discharge port 212 connected to the first cavity 23. The filter assembly 3 includes a cylinder 31, a filter screen 32, and a baffle 33. The cylinder 31 is slidably arranged in the first cavity 23, the filter screen 32 is arranged at one end of the cylinder 31 and connected to the cylinder 31, the cylinder 31 is formed with a second cavity 311, and the cylinder 31 is formed with an opening 314 connecting the first cavity 23 and the second cavity 311, and the baffle 33 is slidably arranged in the second cavity 311; the protective cover 4 is provided at the end of the shell 2 away from the liquid inlet 211, and is linked to the baffle 33; the first elastic member 51 is provided It is placed between the baffle 33 and the shell 2 so that the protective cover 4 blocks the first discharge port 221 under the action of the first elastic member 51, and when the baffle 33 overcomes the elastic force of the first elastic member 51, the protective cover 4 avoids the first discharge port 221. The second elastic member 52 is set between the barrel 31 and the shell 2 so that the filter assembly 3 blocks the second discharge port 212 under the action of the second elastic member 52, and when the filter screen 32 overcomes the elastic force of the second elastic member 52, the filter assembly 3 avoids the second discharge port 212. The water supply device includes at least a first working state, a second working state, and a third working state. When the water supply device is in the first working state, liquid enters through the liquid inlet 211 and passes through the filter screen 32, pushing the baffle 33, causing the protective cover 4 to avoid the first discharge port 221, so that the liquid passing through the filter screen 32 is discharged from the first discharge port 221 through the opening 314 located in the barrel 31. Optionally, the protective cover 4 has a side wall provided on the shell 2 , and when the side wall covers the first discharge port 221 , the first discharge port 221 is blocked, and when the side wall avoids the first discharge port 221 , the first discharge port 221 is opened.

[0049] When the water supply device is in the second working state, the protective cover 4 blocks the first discharge port 221. When the water supply device is in the third working state, the protective cover 4 blocks the first discharge port 221. After the liquid enters through the liquid inlet 211, it pushes the filter screen 32, causing the filter assembly 3 to avoid the second discharge port 212, so that the liquid is discharged through the second discharge port 212. Optionally, the four sides of the filter screen 32 are in contact with the inner wall of the shell 2. When the filter screen 32 is located above the second discharge port 212, the second discharge port 212 is blocked and the second discharge port 212 is closed. When the filter screen 32 moves away from the liquid inlet 211 so that the second discharge port 212 is above the filter screen 32, the second discharge port 212 is opened. It should be noted that the upper side of the filter screen 32 is the side facing the liquid inlet 211.

[0050] There are at least three working states in the water supply device provided by the embodiments of the present disclosure. Through the linkage of the first elastic member 51 with the protective cover 4 and the baffle 33, and the linkage of the second elastic member 52 with the filtering assembly 3, the drainage control under different working states is realized. The water supply device provided by the embodiments of the present disclosure does not require power supply, does not rely on batteries, and there is no risk of intermittent power failure. The water supply device provided by the embodiments of the present disclosure can automatically switch the working mode according to the change of the pressure when the water flow impacts the filter net 32. Without external energy input, the switching of the three working modes of the water supply device in the coral habitat area is realized, which not only ensures the efficient operation of the water supply device, but also fully respects the natural physiological rhythm of corals, and can meet the requirements of a long service life cycle.

[0051] Due to different pressures when the water flow impacts the filter net 32, the speed of the water flow discharged from the first discharge port 221 is different. Since the water flow can only be discharged from the first discharge port 221 when the pressure when the water flow impacts the filter net 32 meets the set pressure, the flow rate of the water flow discharged from the first discharge port 221 can be kept constant within a certain range. The stable and moderate water flow promotes gas exchange and nutrient transport, reduces the possibility of the shedding of symbiotic algae caused by strong water flow or tissue tearing, and reduces the possibility of the accelerated sedimentation rate of suspended sediments covering the coral surface and blocking its photosynthesis in an extremely low flow rate environment.

[0052] Combined Figure 5 、 Figure 6 and Figure 7 As shown, in the first working state, the liquid pushes the baffle 33 to make the protective cover 4 avoid the first discharge port 221, and the liquid is discharged from the first discharge port 221. The first working state can be used as the normal working mode: when there is no or only less blockage on the filter net 32, the liquid flow will normally pass through the filter net 32 and impact the baffle 33 below the filter net 32. The impact force is greater than the elastic force of the first elastic member 51, thereby pushing the first discharge port 221 to open. This is also the normal working state of the device. At this time, the device drains water normally.

[0053] In the second working state, the protective cover 4 blocks the first discharge port 221, and the discharge can be stopped. When the liquid discharge stops, due to the absence of liquid flow or less and less liquid impacting the baffle 33 below the filter net 32, the impact force of the liquid flow is less than the elastic force of the first elastic member 51. The protective cover 4 of the first discharge port 221 closes by the elastic force of the first elastic member 51. At this time, it can prevent external sediment, stones, barnacles and other microorganisms from attaching to the first discharge port 221, reduce the possibility of blockage of the first discharge port 221, and prevent it from affecting the normal operation of the water supply device.

[0054] In the third operating state, liquid pushes the filter screen 32, causing the filter assembly 3 to avoid the second drain port 212, and the liquid is discharged from the second drain port 212. When there is a lot of obstruction on the filter screen 32, the liquid flow through the filter screen 32 decreases, and the impact force on the baffle 33 below the filter screen 32 is less than the elastic force of the first elastic member 51, preventing the first drain port 221 from opening. At this time, the pressure in the device surges, and the filter screen 32, in the blocked state, acts as a baffle. At this time, the liquid flow pushes the filter screen 32, causing the second elastic member 52 below the filter screen 32 to contract, lowering the filter screen 32 and exposing the second drain port 212. The liquid flow then drives the obstruction out through the stone discharge port, clearing the obstruction from the filter screen 32. When the obstruction is removed from the device, the liquid flow through the filter screen 32 increases, and the filter assembly 3 closes the second drain port 212 due to the elastic force of the second elastic member 52. The liquid flow then pushes the baffle 33 below the filter screen 32, and the device resumes normal operation.

[0055] The water supply device provided in the disclosed embodiment achieves automatic switching between three operating modes through an innovatively designed dual-elastic linkage mechanism and a sliding filter assembly 3. Liquid pressure is used to push the baffle 33 and filter screen 32, thereby enabling the protective cover 4 to avoid or block the first discharge port 221 and the filter assembly 3 to avoid or block the second discharge port 212. This eliminates the need for additional complex control mechanisms, reducing manufacturing costs. Furthermore, the device can automatically adjust its operating state based on the liquid flow rate and pressure, making the water supply device more intelligent and automated.

[0056] The water supply device provided by the disclosed embodiments features a multi-state drainage control method, allowing for flexible selection of appropriate drainage paths based on different usage scenarios and needs, improving its applicability and controllability. When used in artificial habitats, it can be adapted as a coral artificial habitat control device with a cleaning function, used to discharge cold water into the habitat during extremely hot summer weather, creating a suitable living environment for corals and preventing heat stress on coral reefs. The water supply device utilizes an innovative dual-elastic linkage mechanism and a sliding filter assembly 3 to automatically switch between three operating modes. The device utilizes a spring with a variable elastic coefficient, ensuring a low and constant outlet flow rate while maintaining high flow rates. This reduces regional mixing of cold water and allows cold water to remain in the coral reef artificial habitat for a longer period of time, aiding coral growth, reproduction, and recovery. Furthermore, the linkage mechanism automatically clears obstructions and automatically covers the water when the device is stopped, significantly improving anti-adhesion efficiency. The water supply device provided by the disclosed embodiments does not rely on electric control or require frequent maintenance and battery replacement, allowing for long-term operation.

[0057] Optionally, the liquid inlet 211 is disposed at one end of the housing 2, and the first discharge port 221 and the second discharge port 212 are disposed on a sidewall of the housing 2. Optionally, the first discharge port 221 is located at an end away from the liquid inlet 211, and the second discharge port 212 is located in the area between the liquid inlet 211 and the first discharge port 221. Optionally, there are multiple first discharge ports 221, and the multiple first discharge ports 221 are evenly distributed along the circumference of the housing 2. Optionally, there are multiple second discharge ports 212, and the multiple second discharge ports 212 are evenly distributed along the circumference of the housing 2.

[0058] Optionally, the opening 314 is located on the side wall of the cylinder 31 .

[0059] Optionally, housing 2 includes a joint housing 21 and a spout housing 22. Joint housing 21 and spout housing 22 are threadedly connected. Joint housing 21 is connected to drain pipe 1. A first discharge port 221 can be provided on spout housing 22, and first discharge port 221 can serve as a spout to discharge liquid. A second discharge port 212 can be provided on joint housing 21, and second discharge port 212 can serve as a discharge port for a mixture of liquid and sand formed after flushing filter screen 32. Optionally, a sealing ring 6 is provided between joint housing 21 and drain pipe 1.

[0060] Optionally, both the first elastic member 51 and the second elastic member 52 may be springs.

[0061] Optionally, the filter 32 is fixedly connected to the cylinder 31 , and the filter 32 can block the second discharge port 212 under the action of the second elastic member 52 , or the filter 32 and the cylinder 31 can form a whole to block the second discharge port 212 under the action of the second elastic member 52 .

[0062] Optionally, the baffle 33 has semicircular grooves corresponding in position (projection) to the mesh holes 321 of the filter screen 32 and having an equal number thereof, and the liquid flow impacts at this position.

[0063] In some specific embodiments, the water supply device also includes a support column 34. The shell 2 is provided with a mounting hole. The support column 34 can be slidably set in the mounting hole. The two ends of the support column 34 are respectively connected to the baffle 33 and the protective cover 4, so that the protective cover 4 and the baffle 33 can be linked. When the liquid pushes the baffle 33, the connection action of the support column 34 can synchronously drive the protective cover 4 to move accordingly, thereby realizing the opening and closing control of the first discharge port 221, making the working process of the water supply device more coordinated and accurate, and improving the working performance and reliability of the device.

[0064] The first elastic member 51 is mounted on the support column 34, providing a stable mounting structure for the first elastic member 51 and effectively preventing it from shifting or shaking during operation. This not only ensures that the first elastic member 51 can properly exert its elastic force and maintain the normal working relationship between the various components of the water supply device, but also extends the service life of the first elastic member 51, reduces the probability of failure caused by elastic member instability, and improves the overall stability of the water supply device. Optionally, one end of the support column 34 is fixedly connected to the baffle 33, and the other end is threadedly connected to the protective cover 4, facilitating installation and removal.

[0065] In some specific embodiments, the elastic coefficient of the second elastic member 52 is greater than the elastic coefficient of the first elastic member 51. Since the elastic coefficient of the second elastic member 52 is greater, it means that a greater external force is required to deform the second elastic member 52, while the first elastic member 51 is more easily compressed or stretched. In this way, when the liquid pressure changes, the water supply device can first meet the conditions for the action of the first elastic member 51, so that the protective cover 4 first performs the corresponding action, such as avoiding or blocking the first discharge port 221, to achieve the switching between the first working state and the second working state. Only when the liquid pressure increases further and reaches the conditions for the action of the second elastic member 52, will the filter assembly 3 overcome the elastic force of the second elastic member 52, avoid the second discharge port 212, and achieve the switching to the third working state. This orderly working state switching enables the water supply device to operate according to the predetermined logic based on the changes in liquid pressure, thereby improving the orderliness and controllability of the water supply device's operation.

[0066] When there is no or only a small amount of blockage on the filter screen 32, the liquid flow will pass through the filter screen 32 normally and impact the baffle 33 below the filter screen 32. The impact force is greater than the elastic force of the first elastic member 51, thereby pushing the first discharge port 221 to open. This is also the normal working state of the device. At this time, the device drains water normally. When there are more blockages on the filter screen 32, the liquid flow passing through the filter screen 32 becomes less, and the impact force hitting the baffle 33 under the filter screen 32 is less than the elastic force of the first elastic member 51, and the first discharge port 221 cannot be opened. At this time, the pressure in the device surges, and the filter screen 32 is equivalent to a baffle in the blocked state. At this time, the liquid flow pushes the filter screen 32 to cause the second elastic member 52 under the filter screen 32 to contract, and the filter screen 32 is lowered to expose the second discharge port 212. The liquid flow can drive the blockage to flow out through the stone discharge port, thereby cleaning the blockage in the filter screen 32. When the blockage is discharged from the device, the liquid flow passing through the filter screen 32 becomes more, and the filter assembly 3 relies on the elastic force of the second elastic member 52 to close the second discharge port 212. The liquid flow can push the baffle 33 under the filter screen 32 again, and the device returns to normal working condition.

[0067] In some specific embodiments, a slider 312 is provided on the cylinder body 31, and a chute 213 is provided on the housing 2. The chute 213 extends along the axial direction of the housing 2, and the slider 312 is slidably engaged with the chute 213. The chute 213 guides the slider 312 to ensure that the cylinder body 31 can slide stably along the axial direction of the housing 2. This enables the filter assembly 3 (the cylinder body 31 and the filter net 32 are part of the filter assembly 3) to accurately adjust its position during operation.

[0068] In some specific embodiments, a lower fixing plate 214 is provided on the housing 2, and an upper fixing plate 313 is provided on the cylinder body 31. The two ends of the second elastic member 52 are respectively connected to the upper fixing plate 313 and the lower fixing plate 214. The lower fixing plate 214 and the upper fixing plate 313 provide a stable installation position for the second elastic member 52. The two ends of the second elastic member 52 are respectively connected to the upper and lower fixing plates 214, which can ensure that the elastic member will not shift or loosen during operation, guaranteeing that the second elastic member 52 can normally exert its elastic function and providing reliable elastic support for the switching of the working state of the water supply device. Through the connection of the second elastic member 52 with the upper and lower fixing plates 214, the movement of the cylinder body 31 and the filter net 32 (part of the filter assembly 3) located on the cylinder body 31 can be effectively controlled. When liquid pressure acts on the filter net 32, it is necessary to overcome the elastic force of the second elastic member 52 to move the cylinder body 31 and the filter net 32 located on the cylinder body 31. The action of this elastic force can keep the cylinder body 31 and the filter net 32 located on the cylinder body 31 in corresponding positions under different liquid pressures, realizing the switching of different working states of the water supply device. For example, when the liquid pressure is relatively small, the elastic force of the second elastic member 52 can keep the cylinder body 31 in the position blocking the second discharge port 212; when the liquid pressure increases to a certain extent, the cylinder body 31 and the filter net 32 located on the cylinder body 31 can overcome the elastic force of the second elastic member 52 and avoid the second discharge port 212, thus realizing different drainage paths.

[0069] In some specific embodiments, the surface of the filter net 32 facing the liquid inlet 211 is conical; along the direction from the center of the filter net 32 to the periphery, the height of the filter net 32 gradually decreases. Since the height of the filter net 32 gradually decreases from the center to the periphery, sand and gravel are more likely to move towards the edge of the filter net 32 and be discharged from the second discharge port 212 during the filtering process. This structural design avoids the accumulation of sand and gravel in the center of the filter net 32 and ensures the normal operation of the water supply device. Sand and gravel can smoothly slide along the conical surface and will not adhere to the filter net 32 for a long time, extending the service life of the filter net 32.

[0070] In some specific embodiments, the first elastic member 51 is a special elastic member whose elastic modulus varies with the compression amount, so that the velocity of the liquid discharged through the first discharge port 221 is consistent. When the water supply device is applied to an artificial habitat, the flow velocity of the liquid at the first discharge port 221 can be made smaller and constant, reducing the mixing of cold water in the area, enabling the cold water to remain in the artificial coral reef habitat for a longer time, and contributing to the growth, reproduction, and recovery of corals.

[0071] Reasonably setting elastic members with different elastic coefficients enables the water supply device to automatically select an appropriate drainage path according to the flow rate and pressure of the liquid. In some specific embodiments, the elastic coefficient of the first elastic member 51 satisfies:

[0072] = ;

[0082] Elastic force of the first elastic member 51: , (Equation 7), The protective cover 4 will start to expose the water supply port at the first discharge port 221 only when the movement amount exceeds the edge height h.

[0083] , (Equation 8),

[0084] Substitute Equation (6) into Equation (7) to obtain: , (Equation 9),

[0085] Substitute Equation (2) into Equation (9) to obtain: , (Equation 10),

[0097] Substituting (Equation 18) and (Equation 19) into (Equation 14) and calculating gives:

[0098] When , , (Equation 20),

[0099] Because it is necessary to control to be a fixed value, except are all device parameters and are fixed values after the device is determined, then can be simplified to the form of .

[0100] It can be seen through Figure 1 that a straight line about the flow velocity can be used to approximately replace it, but it is not intuitive to change the spring stiffness according to the change of the flow velocity, and then change the form of , , , is a straight line about the compression amount , so to ensure that is a fixed value, it is necessary to ensure that the main spring uses a special spring whose spring modulus changes with the compression amount.

[0101] When is a fixed value, an environment suitable for the growth and reproduction of corals, such as temperature, water flow and nutrients, can be created. Especially in the extremely high temperature weather in summer, cold water is artificially supplied to relieve the heat stress of corals and prevent them from bleaching.

[0102] The water supply device provided by the embodiment of the present disclosure realizes the intelligent control of the water flow velocity through the linkage mechanism of the innovatively designed first elastic member and second elastic member and the slide rail type baffle plate component. Maintaining a fixed value helps corals relieve heat stress from extreme weather, helps corals fully feed, discharge harmful metabolites, and promotes the photosynthesis of coral polyps.

[0103] In some specific embodiments, the elastic coefficient of the second elastic member 52 satisfies: ;

[0104] Wherein, is the density of the liquid, is the cross-sectional area inside the housing 2, is the total area of the unblocked regions of the mesh holes 321 of the filter screen 32, is the deformation amount of the first elastic member 51, and is the distance from the top of the protective cover 4 to the top of the first discharge port 221, , is the velocity of the liquid after passing through the filter screen 32, is the resistance coefficient, is the velocity of the liquid when flowing towards the filter screen 32.

[0105] Specifically, since the filter screen 32 is blocked, less fluid impacts the baffle 33, so the force is small and cannot cause a large displacement of the first elastic member 51, that is, the displacement amount , at this time,

[0106] ,

[0107] Then the unblocked mesh opening area is ,

[0108] The cross-sectional area of the blocked mesh opening ,

[0109] The force acting on it is , at this time the second elastic member 52 begins to be compressed, and after calculation, a variable elastic coefficient should be ensured under a small compression amount , otherwise a small blockage or a large flow rate will cause a large deformation of the second elastic member 52, causing the device to change the flow path for anti-blocking cleaning and unable to carry out the water supply work normally.

[0110] In some specific embodiments, the force of the liquid impacting the baffle 33 is F1, and the force of the liquid impacting the filter screen 32 is F2,

[0111] In the case where the water supply device is in the first working state, F1 is greater than the elastic force of the first elastic member 51;

[0112] In the case where the water supply device is in the second working state, F1 is less than the elastic force of the first elastic member 51;

[0113] When the water supply device is in the third operating state, F1 is less than the elastic force of the first elastic member 51, and F2 is greater than the elastic force of the second elastic member 52. The water supply device provided in the embodiment of the present disclosure realizes automatic switching between three operating modes through an innovatively designed dual elastic member linkage mechanism and a sliding filter assembly 3. The pressure of the liquid is used to push the baffle 33 and the filter screen 32, thereby achieving the avoidance or blocking of the first discharge port 221 by the protective cover 4 and the avoidance or blocking of the second discharge port 212 by the filter assembly 3. No additional complex control mechanism is required, which reduces manufacturing costs. The device can also automatically adjust the operating state according to the flow rate and pressure of the liquid, making the operation of the water supply device more intelligent and automated.

[0114] The disclosed embodiments successfully address the issues of traditional water supply devices, such as their high energy dependence and poor ecological compatibility. The water supply device provided by the disclosed embodiments is capable of automatically switching operating modes, adaptively cleaning, and intelligently regulating the flow rate in the coral habitat without the need for external energy input. This ensures the efficient operation of the water supply device while fully respecting the natural physiological rhythms of the corals. Compared to existing technologies, this solution offers significant advantages such as low maintenance costs, strong environmental adaptability, and eco-friendliness. It provides a long-term, reliable, economical, and practical intelligent solution for coral reef ecological restoration projects, demonstrating its unique value and application potential in marine environmental regulation.

[0115] In summary, the water supply device provided by the embodiment of the present disclosure has the following advantages:

[0116] 1. Adaptive cleaning function significantly improves anti-blocking efficiency;

[0117] When the filter 32 is clogged, the pressure feedback mechanism triggers the contraction of the second elastic member 52, automatically switching to cleaning mode (the third operating state). Once the blockage is discharged through the second discharge port 212, the system returns to normal operating mode (the first operating state), without any human intervention or electrical power. Traditional static filters require regular manual cleaning or electric cleaning equipment, which requires manual removal and cleaning, resulting in time-consuming and labor-intensive operations. They also require batteries for power, require excellent sealing, and are costly. The present invention, however, achieves adaptive cleaning through a purely mechanical structure, reducing maintenance costs and avoiding the waterproof sealing challenges associated with electric equipment.

[0118] 2. Constant low flow rate water supply to extend cold water retention time;

[0119] Adopt a main spring (the first elastic member 51) with a variable elastic coefficient, and precisely control the opening degree of the second discharge port 212 through a hydrodynamic model (the flow conservation equation and the momentum theorem) to ensure that the outlet flow velocity is stable within the set range. Through simulation verification, a constant water supply velocity can effectively reduce the mixing of cold water with the surrounding water body, extend the retention time of the cold water layer in the coral reef area, and effectively relieve coral heat stress. Moreover, it avoids the problem of unstable coral growth environment caused by flow velocity fluctuations in traditional devices.

[0120] 3. Multi-mode automatic switching, high reliability;

[0121] According to the dynamic balance of the water flow impact force (F1, F2) and the spring elastic force (Fx1, Fx2), automatically switch among three working modes

[0122] Normal working mode (F1>Fx1): Drain a large amount of water with a constant flow velocity.

[0123] Cleaning mode (0<F1≤Fx1, F2>Fx2): The filter net 32 moves downward, and the second discharge port 212 opens to remove blockages.

[0124] Stop mode (F=0, F=0): The protective cover 4 closes to prevent external impurities from invading.

[0125] Fully mechanically controlled, without complex circuits or sensors, suitable for long-term underwater operations, and the failure rate is lower than that of traditional electric equipment. Automatically seal when stopped to avoid secondary blockages caused by barnacle and sediment attachment.

[0126] 4. Modular design, strong adaptability;

[0127] The area of the filter net 32 and the parameters of the first elastic member 51 and the second elastic member 52 can be customized according to the water flow conditions and impurity types in different sea areas. Optimize the shape of the baffle 33 and the stiffness curves of the first elastic member 51 and the second elastic member 52 through CFD (Computational Fluid Dynamics, abbreviated as CFD) simulation.

[0128] Suitable for high-turbidity sea areas (such as nearshore coral restoration) or low-flow deep-sea environments, and the adaptability far exceeds that of traditional fixed filters. Can be extended to fields such as sewage treatment and aquaculture, and only need to adjust the size of the mesh holes 321 and the spring parameters to reuse the technical solution.

[0129] 5. Energy-saving and environmental protection, strong sustainability;

[0130] Completely rely on water flow power to drive, without external energy input, and the materials can be selected from corrosion-resistant alloys or environmentally friendly composite materials. Zero carbon emissions, meeting the sustainable development requirements of marine ecological restoration. The long-term operation cost is lower.
