Description

Technical Field

[0001] This invention relates to the technical field of aquatic animal farming, specifically to a base-type truss aquaculture platform with a lifting net cage and method for improving wind and wave resistance. Background Technology

[0002] Aquaculture cages are facilities used in aquaculture, where aquatic animals such as fish and shellfish are kept in specific net cages to achieve a highly efficient and intensive farming method. This method has several advantages, including increasing stocking density, reducing competition among aquatic animals, and improving the farming environment.

[0003] Open sea areas lack shelter and have strong currents. Existing mainstream deep-sea cages are unable to withstand the impact of strong currents. On the other hand, the aquaculture species also find it difficult to withstand the continuous impact of water currents of more than 1.0 m / s for a long time, which can easily lead to fatigue and death. Therefore, some cages are designed with a lifting mode, which can sink in the event of large waves to avoid large waves and improve their resistance to wind and waves.

[0004] However, after the cages sink, the water flow velocity at the bottom remains unpredictable due to the influence of wind and waves. At this time, under the impact of the water flow, the cultured organisms inside the cages are easily swept to one side, and due to stress response, they are prone to injury from collisions. Therefore, there is still room for improvement in the protection of cultured organisms in existing aquaculture cages.

[0005] Furthermore, as living organisms, a short period of adverse farming conditions can cause mass mortality of farmed animals, resulting in irreparable losses. Therefore, the response speed for the protection of farmed animals needs to be further improved. Summary of the Invention

[0006] The purpose of this invention is to provide a base-mounted truss aquaculture platform with a lifting net cage and method for improving wind and wave resistance, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A base-mounted truss aquaculture platform with lifting cage for improving wind and wave resistance includes a cage body and a closable cover on the top of the cage body. Both the cage body and the cover are provided with multiple openings.

[0009] The improved wind and wave resistance of the base-type truss aquaculture platform lifting cage also includes:

[0010] The base box is fixed to the bottom side of the box body by fasteners. There are four base boxes, which are located on each side of the box body to form a base structure. The base box is equipped with a counterweight control mechanism. The counterweight control mechanism can pump water into the base box or pump water out of the base box to increase or decrease the weight of the base structure and cause the box body to sink or float.

[0011] A lateral shielding mechanism is provided on each of the bottom boxes and located on the side of the box body. The lateral shielding mechanism is connected to the counterweight control mechanism. When the weight of the bottom box increases and the box body sinks, the lateral shielding mechanism can move toward the box body to block the opening on the side of the box body.

[0012] As a further aspect of the present invention: the counterweight control mechanism includes a sealing sliding assembly disposed in the base box and a threaded drive assembly connected to the sealing sliding assembly. The threaded drive assembly is connected to the lateral shielding mechanism and can drive the sealing sliding assembly to move along the length direction of the base box.

[0013] As a further embodiment of the present invention: the sealing sliding assembly includes a piston plate that is slidably disposed inside the bottom box, and a first one-way valve and a second one-way valve are installed on the side of the bottom box near the piston plate. The first one-way valve and the second one-way valve have opposite conduction directions and respectively form a water inlet passage and a drainage passage.

[0014] As a further embodiment of the present invention: the threaded drive assembly includes a drive motor installed inside the base box, a lead screw connected to the output end of the drive motor, and a threaded sleeve sleeved on the lead screw and threadedly connected to the lead screw, wherein the end of the threaded sleeve away from the drive motor is fixedly connected to the piston plate, and the threaded sleeve is also connected to the lateral shielding mechanism.

[0015] As a further embodiment of the present invention: the lateral shielding mechanism includes a side plate movably disposed on the side of the box body, the side plate being connected to a shifting structure installed on the bottom box, the shifting structure being connected to a rotating push-pull assembly disposed inside the bottom box, the rotating push-pull assembly being able to drive the side plate toward or away from the box body through the shifting structure.

[0016] As a further embodiment of the present invention: the side plate is provided with multiple through holes. When the rotating push-pull assembly drives the side plate toward the box body through the displacement structure and makes the side plate fit against the outer wall of the box body, the through holes and the opening are misaligned.

[0017] As a further embodiment of the present invention: the switching structure includes a guide fixed on the base box and a connecting arm slidably connected to the guide, the connecting arm being sealed and slidably fitted to the upper part of the base box, and a protruding post being fixedly provided at the bottom of the connecting arm, the protruding post extending into the interior of the base box and connected to the rotating push-pull assembly.

[0018] The base box is provided with a strip-shaped through groove for the movement of the protruding column, the connecting arm is fixedly connected to a fixing frame, and the side plate is connected to the fixing frame through multiple sets of elastic telescopic members.

[0019] As a further embodiment of the present invention: the rotating push-pull assembly includes a disc rotatably mounted inside the base box and a connecting rod rotatably mounted at the eccentric position of the disc, wherein the end of the connecting rod away from the disc is rotatably connected to the protrusion.

[0020] The bottom box also contains a rotatable gear, the rotation shafts of which are connected to the disk via a transmission belt, and a rack plate is fixed to the outer wall of the threaded sleeve, which meshes with the gear.

[0021] As a further embodiment of the present invention: the elastic telescopic member includes a guide cylinder fixed on the fixed frame, a telescopic rod that is sealed and slidably fitted with the guide cylinder, and a cylindrical spring disposed inside the guide cylinder. The telescopic rod is fixedly connected to the side plate, one end of the cylindrical spring is connected to the inner wall of the guide cylinder, and the other end is connected to the end of the telescopic rod away from the side plate.

[0022] The method of using the base-type truss aquaculture platform with lifting cage to improve wind and wave resistance includes the following steps:

[0023] Step 1: Select a suitable breeding area and place the net cages into the breeding site;

[0024] Step two: The observation station monitors the wind and wave conditions in the aquaculture area in real time;

[0025] Step 3: When large waves are generated, the counterweight control mechanism pumps water into the bottom tank to increase its weight, causing the tank to sink. The side shielding mechanism moves towards the tank to block the opening on the side of the tank.

[0026] Step four: As the wind and waves subside, the counterweight control mechanism removes water from the bottom tank to reduce its weight, causing the tank to float. The lateral shielding mechanism moves away from the tank, releasing the blockage at the opening and restoring the tank's water exchange capacity.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] This application sets multiple bottom boxes at the bottom of the cage and installs a counterweight control mechanism inside the bottom boxes. When there are large waves, the counterweight control mechanism is used to pump water into the bottom boxes to realize the variability of the counterweight, so that the cage can automatically sink according to the waves and improve its resistance to wind and waves.

[0029] Secondly, during the sinking process of the net cage, the counterweight control mechanism can drive the lateral shielding mechanism to move towards the cage body, which can shield the cage body and prevent water flow from impacting the inside of the cage body, so that the aquatic organisms will collide with each other due to stress response and cause damage, thus providing comprehensive protection for the aquatic organisms.

[0030] By setting multiple through holes on the side panel and staggering the through holes and openings after the side panel is attached to the side of the tank, the water exchange efficiency inside the tank can be maintained without affecting the side panel's ability to effectively block the openings on the side of the tank, thus ensuring the replacement of the aquaculture environment.

[0031] This application employs a combination of container upgrades and container shielding to provide comprehensive protection against wind, waves, and water flow. Furthermore, the combined protection method ensures a rapid response time for the protected species, minimizing the damage caused by climate and water flow. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0045] Please see Figures 1-10 In this embodiment of the invention, the base-type truss aquaculture platform lifting cage with improved wind and wave resistance includes a cage body 1 and a cage cover 2 that can be opened and closed on the top of the cage body 1. Both the cage body 1 and the cage cover 2 are provided with multiple openings 4.

[0046] The improved wind and wave resistance of the base-type truss aquaculture platform lifting cage also includes:

[0047] The base box 3 is fixed to the bottom side of the box body 1 by fasteners 26. There are four base boxes 3, which are located on each side of the box body 1 to form a base structure. The base box 3 is equipped with a counterweight control mechanism. The counterweight control mechanism can pump water into the base box 3 or pump water out of the base box 3 to increase or decrease the weight of the base structure and drive the box body 1 to sink or float.

[0048] A lateral shielding mechanism is provided on each of the bottom boxes 3 and located on the side of the box body 1. The lateral shielding mechanism is connected to the counterweight control mechanism. When the weight of the bottom box 3 increases and the box body 1 sinks, the lateral shielding mechanism can move toward the box body 1 to block the opening 4 on the side of the box body 1.

[0049] Furthermore, the counterweight control mechanism establishes communication with the observation station. When the observation station detects large waves, it sends a control signal to the counterweight control mechanism. The counterweight control mechanism then operates, pumping water into the bottom tank 3, increasing its weight. This causes the bottom tank 3 to cause the tank body 1 to sink, avoiding large waves and preventing instability or damage due to prolonged strong current impact. Simultaneously, the counterweight control mechanism pumps water into the bottom tank 3, also moving the side shielding mechanism. The side shielding mechanism moves towards the tank body 1, ultimately sealing the opening 4 on the side of the tank body 1. This prevents strong currents from entering the tank body 1 through the opening 4 and impacting the farmed animals inside, thus preventing fatigue and death.

[0050] Therefore, this application provides multiple bottom boxes 3 at the bottom of the cage 1, with each bottom box 3 located on the lower side of the cage 1. This also serves to stabilize the counterweight. By using the counterweight control mechanism to pump water into the bottom box 3, the counterweight can be made variable, allowing the cage to automatically rise and fall according to wind and waves, thus improving its resistance to wind and waves. Furthermore, the side shielding mechanism can block the opening 4 on the side of the cage 1, effectively preventing strong currents from entering the cage 1 and causing impact fatigue to the aquaculture organisms inside the cage 1, thus providing comprehensive protection for the aquaculture organisms.

[0051] The container 1 has a cable that connects to the bottom of the water or other fixed points, allowing the container 1 to move within a certain range in the up, down, left, and right directions, but preventing the container 1 from drifting too far and causing it to lose control.

[0052] Please refer to it again. Figure 4 , Figure 7 as well as Figure 10The counterweight control mechanism includes a sealing sliding assembly disposed within the base box 3 and a threaded drive assembly connected to the sealing sliding assembly. The threaded drive assembly is connected to the lateral shielding mechanism and can drive the sealing sliding assembly to move along the length direction of the base box 3. The sealing sliding assembly includes a piston plate 14 that is slidably disposed inside the base box 3, and a first one-way valve 19 and a second one-way valve 20 are installed on the side of the base box 3 near the piston plate 14. The first one-way valve 19 and the second one-way valve 20 have opposite conduction directions and respectively form a water inlet passage and a drainage passage.

[0053] Specifically, when the threaded drive assembly drives the piston plate 14 to slide away from the first one-way valve 19 and the second one-way valve 20 inside the bottom box 3, the first one-way valve 19 is open while the second one-way valve 20 is closed. As a result, external water is drawn into the bottom box 3 through the first one-way valve 19, thereby increasing the weight of the bottom box 3 so that the box 1 can sink. This improves the wind and wave resistance of the net cage and prevents excessive wind and waves from causing excessive impact on the net cage and adversely affecting the growth environment of the aquaculture objects inside the box 1.

[0054] Conversely, when the wind and waves subside, the threaded drive assembly drives the piston plate 14 to slide within the bottom box 3 close to the first one-way valve 19 and the second one-way valve 20. During this process, the first one-way valve 19 is not open, while the second one-way valve 20 is open. Therefore, the contents previously drawn into the bottom box 3 through the first one-way valve 19 can be discharged through the second one-way valve 20, thereby reducing the weight of the bottom box 3 so that the box body 1 can float.

[0055] The threaded drive assembly includes a drive motor 15 installed inside the base box 3, a lead screw 16 connected to the output end of the drive motor 15, and a threaded sleeve 17 sleeved on the lead screw 16 and threadedly connected to the lead screw 16. The end of the threaded sleeve 17 away from the drive motor 15 is fixedly connected to the piston plate 14. The threaded sleeve 17 is also connected to the lateral shielding mechanism.

[0056] Specifically, the drive motor 15 establishes communication with the observation station. When the observation station detects large waves, it sends a control signal to the drive motor 15. Subsequently, the drive motor 15 drives the lead screw 16 to rotate in the forward direction. The threaded sleeve 17 engages with the lead screw 16. The threaded sleeve 17 then drives the piston plate 14 to slide towards the drive motor 15 inside the bottom box 3, pumping water into the bottom box 3 through the first one-way valve 19. At the same time, the threaded sleeve 17 also drives the side shielding mechanism to move, and the side shielding mechanism blocks the opening 4 on the side of the box body 1.

[0057] Conversely, when the wind and waves subside, the drive motor 15 drives the lead screw 16 to rotate in the opposite direction. As a result, the threaded sleeve 17 engages with the lead screw 16 again. The threaded sleeve 17 then pushes the piston plate 14 to slide away from the drive motor 15 within the bottom box 3. Water in the bottom box 3 is then discharged through the second one-way valve 20. At the same time, the lateral shielding mechanism releases the blockage of the opening 4 to restore the water exchange efficiency of the net cage.

[0058] It should be further explained that the sliding of the piston plate 14 within the bottom box 3 is achieved through the threaded engagement of the threaded sleeve 17 and the lead screw 16. This is because the threaded engagement between the threaded sleeve 17 and the lead screw 16 has the characteristics of high precision and stability, thus ensuring a uniform speed during the two processes of water entering the bottom box 3 and exiting the bottom box 3 during pumping and drainage, thereby making the descent and ascent of the net box more stable.

[0059] Please refer to it again. Figure 3 and Figure 7 The lateral shielding mechanism includes a side plate 6 movably disposed on the side of the housing 1. The side plate 6 is connected to a displacement structure installed on the bottom box 3. The displacement structure is connected to a rotating push-pull assembly disposed inside the bottom box 3. The rotating push-pull assembly can drive the side plate 6 to move toward or away from the housing 1 through the displacement structure.

[0060] Please refer to it again. Figure 6 The side plate 6 is provided with multiple through holes 5. When the rotating push-pull assembly drives the side plate 6 toward the box 1 through the displacement structure and makes the side plate 6 fit against the outer wall of the box 1, the through holes 5 are misaligned with the through opening 4.

[0061] Furthermore, if the side plate 6 does not have the through holes 5, when the rotating push-pull assembly drives the side plate 6 toward the box 1 through the switching structure and makes the side plate 6 fit against the outer wall of the box 1, the side plate 6 can also block the opening 4, preventing strong flow from impacting the aquaculture objects in the box 1. However, with this arrangement, when the side plate 6 is not fitted against the outer wall of the box 1, the side plate 6 will obstruct the side of the box 1, which is not conducive to the flow of water through the box 1, thereby reducing the water exchange efficiency. Therefore, this application provides multiple through holes 5 on the side plate 6, and the through holes 5 are staggered with the opening 4, so that the side plate 6 can effectively block the opening 4 on the side of the box 1 without affecting the water exchange efficiency in the box 1.

[0062] Please refer to it again. Figure 3 , Figure 8 , Figure 9 as well as Figure 10 The switching structure includes a guide member 7 fixed to the base box 3 and a connecting arm 8 slidably connected to the guide member 7. The connecting arm 8 is sealed and slidably fitted to the upper part of the base box 3, and a protruding post 10 is fixedly provided at the bottom of the connecting arm 8. The protruding post 10 extends into the interior of the base box 3 and is connected to the rotating push-pull assembly. The base box 3 is provided with a strip-shaped through groove 25 for the movement of the protruding post 10. The connecting arm 8 is fixedly connected to a fixing frame 9, and the side plate 6 is connected to the fixing frame 9 through multiple sets of elastic telescopic members.

[0063] It should be further noted that the end of the connecting arm 8 away from the fixed frame 9 should have sufficient length. The purpose of this is that when the rotating push-pull assembly drives the connecting arm 8 to slide through the protrusion 10, the connecting arm 8 can always seal the strip groove 25, preventing water from entering the bottom box 3 and adversely affecting the operation of the drive motor 15 inside the bottom box 3.

[0064] The rotating push-pull assembly includes a disc 24 rotatably mounted inside the base box 3 and a connecting rod 23 rotatably mounted eccentrically on the disc 24. The end of the connecting rod 23 away from the disc 24 is rotatably connected to the protruding post 10. A gear 22 is also rotatably mounted inside the base box 3. The rotation shafts of the gear 22 and the disc 24 are connected by a transmission belt 18. A rack plate 21 is fixed to the outer wall of the threaded sleeve 17, and the rack plate 21 meshes with the gear 22.

[0065] During the process of pumping water to increase weight, the rack plate 21 moves together with the threaded sleeve 17. Then, the rack plate 21 can drive the gear 22 to rotate. The rotation shaft of the gear 22 drives the disc 24 to rotate half a revolution through the transmission belt 18. Then, the disc 24 pulls the protrusion 10 and the connecting arm 8 to slide through the connecting rod 23. The connecting arm 8 drives the side plate 6 to move towards the box 1 through the fixing frame 9 and multiple sets of elastic telescopic members. Finally, the side plate 6 fits against the outer wall of the box 1, effectively sealing the opening 4 on the side of the box 1. This prevents strong current from entering the box 1 through the opening 4 and causing impact fatigue to the aquaculture objects inside the box 1. Therefore, it can protect the aquaculture objects when there are large waves.

[0066] Conversely, during the drainage and weight reduction process, the gear 22 drives the disc 24 to rotate in the opposite direction by half a turn, and the connecting arm 8, through the fixing frame 9 and multiple sets of elastic telescopic components, drives the side plate 6 to separate from the box 1, thus releasing the blockage of the opening 4 and restoring the water exchange efficiency.

[0067] The elastic telescopic component includes a guide cylinder 11 fixed on the fixing frame 9, a telescopic rod 12 that is sealed and slidably fitted with the guide cylinder 11, and a cylindrical spring 13 disposed inside the guide cylinder 11. The telescopic rod 12 is fixedly connected to the side plate 6. One end of the cylindrical spring 13 is connected to the inner wall of the guide cylinder 11, and the other end is connected to the end of the telescopic rod 12 away from the side plate 6.

[0068] When the connecting arm 8 moves the fixing frame 9 toward the box 1, after the side plate 6 contacts the side of the box 1, as the fixing frame 9 continues to move, the telescopic rod 12 and the guide cylinder 11 will slide relative to each other, and the column spring 13 will be gradually compressed. Therefore, after the movement of the connecting arm 8 and the fixing frame 9 is completed, the column spring 13 is in a compressed state. Under the elastic force of the column spring 13, the tightness of the fit between the side plate 6 and the outer wall of the box 1 is ensured, thus ensuring an effective protection effect for the aquatic animals.

[0069] As another embodiment of the present invention, a method for using the base-type truss aquaculture platform lifting cage with improved wind and wave resistance is also proposed, including the following steps:

[0070] Step 1: Select a suitable breeding area and place the net cages into the breeding site;

[0071] Step two: The observation station monitors the wind and wave conditions in the aquaculture area in real time;

[0072] Step 3: When large waves are generated, the counterweight control mechanism pumps water into the bottom box 3 to increase its weight, causing the box 1 to sink. The side shielding mechanism moves toward the box 1 to block the opening 4 on the side of the box 1.

[0073] Step four: As the wind and waves subside, the counterweight control mechanism removes water from the bottom tank 3 to reduce its weight, causing the tank 1 to float. The lateral shielding mechanism moves away from the tank 1, releasing the blockage of the opening 4 and restoring the water exchange capacity of the tank 1.

[0074] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0075] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

The end of the connecting rod (23) away from the disc (24) is rotatably connected to the protrusion (10). The bottom box (3) is also rotatably installed with a gear (22). The rotation shafts of the gear (22) and the disc (24) are connected by a transmission belt (18). The outer wall of the threaded sleeve (17) is fixed with a rack plate (21), which meshes with the gear (22).

9. The base-mounted truss aquaculture platform lifting cage with improved wind and wave resistance according to claim 7, characterized in that, The elastic telescopic component includes a guide cylinder (11) fixed on the fixed frame (9), a telescopic rod (12) that is sealed and slidably fitted with the guide cylinder (11), and a cylindrical spring (13) disposed in the guide cylinder (11). The telescopic rod (12) is fixedly connected to the side plate (6). One end of the cylindrical spring (13) is connected to the inner wall of the guide cylinder (11), and the other end is connected to the end of the telescopic rod (12) away from the side plate (6).

10. The method of using the base-type truss aquaculture platform lifting cage with improved wind and wave resistance as described in claim 1, characterized in that, Includes the following steps: Step 1: Select a suitable breeding area and place the net cages into the breeding site; Step two: The observation station monitors the wind and wave conditions in the aquaculture area in real time; Step 3: When a large wave occurs, the counterweight control mechanism pumps water into the bottom box (3) to increase its weight, causing the box (1) to sink. The side shielding mechanism moves toward the box (1) to block the opening (4) on the side of the box (1). Step four: As the wind and waves subside, the counterweight control mechanism removes water from the bottom tank (3) to reduce its weight, causing the tank (1) to float. The lateral shielding mechanism moves away from the tank (1), releasing the blockage of the opening (4) and restoring the water exchange capacity of the tank (1).
