Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, specifically to a marine ranch. Background Technology

[0002] Marine ranching is an ecosystem established in the ocean through a combination of artificial intervention and the natural environment, aiming at the sustainable use, protection, and restoration of marine resources. Traditional fishery resources are gradually decreasing, and the issue of fisheries sustainability is becoming increasingly prominent. Therefore, marine ranching promotes the healthy growth and reproduction of marine life through measures such as artificial propagation, planting marine organisms, improving water quality, and creating a suitable ecological environment, thereby achieving ecological restoration. However, existing marine ranching systems still have some shortcomings.

[0003] The invention patent with publication number CN102972316A discloses a semi-submersible marine ranch. The upper part of the pipe frame is connected to a semi-submersible tower with a cylindrical structure, and the inner space enclosed by the pipe frame is connected to the inner space of the semi-submersible tower. A detachable net has a main net with a farming space similar to the inner space of the pipe frame. The upper part of the main net has a small opening connected to a net neck. The main net and the pipe frame are connected by a detachable snap fastener. The detachable net installed inside the pipe frame provides a large farming space during the farming stage and is located at a greater underwater depth, thus offering excellent protection against wind and waves. The opening at the top of the net neck provides some space for recreational fishing. For centralized harvesting, simply removing the connecting parts between the detachable net and the pipe frame allows the entire detachable net to be lifted for centralized harvesting. It has the advantages of novel structure, good deployment stability, large farming capacity, and convenient harvesting. While the aforementioned marine ranches facilitate harvesting, they cannot effectively manage fish waste in a closed and centralized manner, which could negatively impact the ecological environment in the long run. Furthermore, existing marine ranches cannot be quickly connected and assembled as a whole, nor can they utilize buoyancy to automatically compress the assembled structure. Summary of the Invention

[0004] In view of the problems existing in existing marine ranches, this invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a marine ranch, comprising an outer shell, a connecting shell mounted on the outer shell, a column threadedly connected to the connecting shell, a mesh plate fixedly connected to the side of the column, a connecting ring fixedly connected to the column, a connecting plate mounted on the connecting ring, a first float and a pressure block slidably mounted on the column, a leaf spring disposed between two adjacent connecting plates, a connecting belt fixedly connected to the first float, the connecting belt being guided and connected to the pressure block via a guide block, the guide block being fixedly mounted on the column, an adjustment assembly disposed on the side of the outer shell, a baffle mounted on the adjustment assembly, a docking assembly disposed between the outer shell and the connecting shell, a connecting frame mounted on the docking assembly, a third connecting plate slidably mounted within the connecting frame, a third spring and a second connecting plate fixedly connected to the third connecting plate, and a turntable rotatably mounted on the outer shell.

[0006] As a preferred embodiment of the present invention, a second float is fixedly connected below the first float, and the first float and the pressure block are parallel to each other.

[0007] As a preferred embodiment of the present invention, the column is provided with a groove for sliding the first float and the pressure block, and the pressure block forms a first sliding structure with the column through the first float, the connecting belt and the guide block.

[0008] As a preferred embodiment of the present invention, a rubber plate is fixedly connected to the connecting plate, and the rubber plate and the connecting ring closest to the rubber plate are slidably connected.

[0009] As a preferred embodiment of the present invention, mounting grooves are provided on both sides of the connecting plate, and magnetic blocks are fitted into the mounting grooves. The magnetic blocks are fixedly connected to the leaf springs, and the connecting plate is made of magnetic metal.

[0010] As a preferred embodiment of the present invention, the adjustment assembly includes a support plate disposed on the side of the housing, a rubber wheel rotatably mounted on the support plate, a rotating rod fixedly connected to the rubber wheel, an electric push rod fixedly connected to the support plate, a first connecting plate fixedly connected to the electric push rod, a first spring mounted on the first connecting plate, and a pressure plate connected to the first spring.

[0011] As a preferred embodiment of the present invention, the rubber roller, the rotating rod and the baffle are fixedly connected as an integral structure, the rotating rod passes through the interior of the outer shell, the baffle has a chamfered structure on all four sides, and the first connecting plate passes through the support plate.

[0012] As a preferred embodiment of the present invention, the pressure plate forms a pressing structure with the first spring and the rubber rollers, and the rubber rollers are evenly distributed below the pressure plate.

[0013] As a preferred embodiment of the present invention, the docking assembly includes a first connecting block fixedly connected to the outer shell, a second connecting plate slidably installed inside the first connecting block, a slider fixedly connected to the first connecting block, a second spring installed inside the slider, a slide plate fixedly connected to the second spring, a second connecting block disposed on the outer side of the slide plate, the second connecting block being fixedly connected to the connecting shell, a traction steel rope fixedly connected to the slide plate, and the traction steel rope being guided by a first guide wheel and a second guide wheel to connect to the second connecting plate.

[0014] As a preferred embodiment of the present invention, the third connecting plate is provided with a beveled surface, and the third connecting plate forms a second sliding structure with the connecting frame through the beveled surface and the turntable.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The device is equipped with magnetic blocks, leaf springs, and connecting plates. By installing the rubber plates on the connecting plates into adjacent connecting rings, multiple columns can be spliced ​​together. After multiple columns are spliced ​​together, the magnetic blocks and leaf springs can be used to tighten the adjacent connecting plates, ensuring that the entire device can be spliced ​​into a circular structure to ensure the overall stability of the device. This achieves the function of convenient splicing and disassembly. After disassembly, the overall space occupied by the device can be reduced, making it convenient for recycling and storage.

[0016] 2. The device achieves the function of pressing the assembled structure through the first float, connecting belt, pressure block and guide block. After the columns on the device are assembled by the leaf springs, the first float can be raised by buoyancy. When the float rises, the connecting belt will pull the pressure block down under the guidance of the guide block. When the pressure block is pressed down, it can press the top of the leaf spring, thus realizing the function of automatic pressing. This solves the problem that existing marine ranches cannot use buoyancy to automatically press the assembled structure.

[0017] 3. The device is equipped with an adjustment assembly and baffles. By extending the electric push rod on the adjustment assembly, the first connecting plate slides within the support plate. Simultaneously, the support plate causes the pressure plate to slide, while the first spring presses down on the pressure plate, causing it to abut against the rubber roller. This rotates the rubber roller and the rotating rod, changing the multiple baffles from a horizontal to a vertical position. This allows the device to adjust the communication between the outer shell and the connecting shell, adjusting the baffles to... Figure 3 When in the horizontal position, the entire device can be kept closed, thus collecting fish feces.

[0018] 4. The device is equipped with a docking assembly. After the top of the outer shell is closed by the baffle, the turntable can be rotated. The turntable abuts against the beveled surface of the third connecting plate, causing the third connecting plate to be housed inside the connecting frame until the turntable is located in the cavity between the top of the outer shell and the baffle, thus achieving the re-sealing function. During the sealing process, the second connecting plate moves upward and pulls the traction steel rope. The traction steel rope pulls the sliding plate until the sliding plate disengages from the second connecting block on the connecting shell, completing the disengagement and engagement of the outer shell and the connecting shell. The outer shell after secondary sealing can then be removed from the bottom of the device, realizing the function of closed recycling. This solves the problem that existing marine ranches cannot conduct closed and centralized treatment of fish feces, and long-term use will affect the ecological environment.

Detailed Implementation

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] like Figures 1-12As shown, a marine ranch includes an outer shell 1, a connecting shell 2 mounted on the outer shell 1, a column 3 threadedly connected to the connecting shell 2, a mesh plate 4 fixedly connected to the side of the column 3, a connecting ring 11 fixedly connected to the column 3, a connecting plate 7 mounted on the connecting ring 11, a first float 5 and a pressure block 12 slidably mounted on the column 3, a leaf spring 10 disposed between two adjacent connecting plates 7, a connecting belt 14 fixedly connected to the first float 5, the connecting belt 14 being guided and connected to the pressure block 12 via a guide block 15, the guide block 15 being fixedly mounted on the column 3, an adjustment component 17 disposed on the side of the outer shell 1, a baffle 18 mounted on the adjustment component 17, a docking component 19 disposed between the outer shell 1 and the connecting shell 2, a connecting frame 22 mounted on the docking component 19, a third connecting plate 21 slidably mounted inside the connecting frame 22, a third spring 23 and a second connecting plate 20 fixedly connected to the third connecting plate 21, and a turntable 25 rotatably mounted on the outer shell 1. When the device is in use, the column 3 is screwed into the connecting shell 2. The leaf spring 10 connects the two adjacent connecting plates 7. After the connection is completed, under the action of buoyancy, the first float 5 moves upward, thereby causing the connecting belt 14 to pull the pressure block 12 downward under the guidance of the guide block 15. When the pressure block 12 moves downward, it will press the leaf spring 10, thereby ensuring that the two adjacent connecting plates 7 remain fixed after connection. The device can change the vertical or horizontal state of the baffle 18 by adjusting the component 17. When the baffle 18 is horizontal, the top of the shell 1 is closed to facilitate the subsequent collection of fish feces. When collecting feces, the turntable 25 can be rotated. The turntable 25 acts on the docking component 19 through the third connecting plate 21 and the second connecting plate 20. The docking component 19 can close the top of the shell 1 again and release the locking state between the shell 1 and the connecting shell 2.

[0026] In this embodiment, a second float 6 is fixedly connected below the first float 5. The first float 5 and the pressure block 12 are parallel to each other. The second float 6 cooperates with the first float 5 to facilitate the pressing function after the device is assembled as a whole, thus ensuring the overall stability of the device.

[0027] In this embodiment, the column 3 is provided with a groove 13 for sliding the first float 5 and the pressure block 12. The pressure block 12 forms a first sliding structure with the column 3 through the first float 5, the connecting belt 14 and the guide block 15. Through the first sliding structure on the device, the first float 5 can pull the pressure block 12 down through the connecting belt 14 when it moves up, so as to realize the pressing function after splicing.

[0028] In this embodiment, a rubber plate 16 is fixedly connected to the connecting plate 7. The rubber plate 16 and the connecting ring 11 closest to the rubber plate 16 are slidably connected. Adjacent connecting rings 11 can slide around the circumference of the connecting ring 11, which facilitates disassembly and docking and enhances the convenience of using the device.

[0029] In this embodiment, mounting grooves 8 are provided on both sides of the connecting plate 7. A magnetic block 9 is fitted into the mounting groove 8. The magnetic block 9 is fixedly connected to the leaf spring 10. The connecting plate 7 is made of magnetic metal. The magnetic block 9, together with the mounting groove 8, can make the leaf spring 10 stably connect to two adjacent connecting plates 7, thus enhancing the practicality of the device.

[0030] In this embodiment, the adjustment assembly 17 includes a support plate 1701 disposed on the side of the housing 1. A rubber wheel 1702 is rotatably mounted on the support plate 1701. A rotating rod 1703 is fixedly connected to the rubber wheel 1702. An electric push rod 1704 is fixedly connected to the support plate 1701. A first connecting plate 1705 is fixedly connected to the electric push rod 1704. A first spring 1706 is mounted on the first connecting plate 1705. A pressure plate 1707 is connected to the first spring 1706. This device can extend or shorten the electric push rod 1704 to drive the first connecting plate 1705 to slide within the support plate 1701. At the same time, the pressure plate 1707 slides, and the first spring 1706 causes the pressure plate 1707 to abut against the rubber wheel 1702, causing the rubber wheel 1702 to drive the rotating rod 1703 and the baffle 18 to rotate, so as to adjust the vertical or horizontal state of the baffle 18.

[0031] In this embodiment, the rubber roller 1702, the rotating rod 1703, and the baffle 18 are fixedly connected as an integral structure. The rotating rod 1703 passes through the interior of the outer shell 1, and the baffle 18 has a chamfered structure on all four sides. The first connecting plate 1705 passes through the support plate 1701. The rotation of the rubber roller 1702 and the rotating rod 1703 drives the baffle 18 to rotate. After the baffle 18 is adjusted to a horizontal state, the function of sealing the top of the outer shell 1 can be realized.

[0032] In this embodiment, the pressure plate 1707 forms a pressing structure with the rubber roller 1702 through the first spring 1706. The rubber rollers 1702 are evenly distributed below the pressure plate 1707. The pressing structure on the device increases the friction between the pressure plate 1707 and the rubber roller 1702, so that the pressure plate 1707 can drive the rubber roller 1702 to rotate when it moves.

[0033] In this embodiment, the docking assembly 19 includes a first connecting block 1901 fixedly connected to the outer shell 1, a second connecting plate 20 slidably installed inside the first connecting block 1901, a slider 1902 fixedly connected to the first connecting block 1901, a second spring 1903 installed inside the slider 1902, a slide plate 1905 fixedly connected to the second spring 1903, a second connecting block 1904 provided on the outer side of the slide plate 1905, the second connecting block 1904 being fixedly connected to the connecting shell 2, a traction steel rope 1906 fixedly connected to the slide plate 1905, the traction steel rope 1906 being guided by the first guide wheel 1907 and the second guide wheel 1908 and connected to the second connecting plate 20, a third connecting plate 21 having a chamfered surface 24, the third connecting plate 21 forming a second sliding structure with the connecting frame 22 through the chamfered surface 24 and the turntable 25. When the turntable 25 rotates, the turntable 25 abuts against the third connecting plate 21 through the inclined surface 24, causing the third connecting plate 21 to drive the second connecting plate 20 to move upward. The second connecting plate 20 pulls the traction steel rope 1906. Under the guidance of the first guide wheel 1907 and the second guide wheel 1908, the traction steel rope 1906 pulls the slide plate 1905 to slide. The second spring 1903 on the slide plate 1905 is compressed until the slide plate 1905 disengages from the second connecting block 1904. At this time, after the top of the outer shell 1 is closed twice by the turntable 25, the function of separating the outer shell 1 from the bottom of the connecting shell 2 can be realized.

[0034] It should be noted that this invention is a marine ranching system. Firstly, when using the device, as... Figures 1-8 As shown, the column 3 is screwed into the connecting shell 2, and the magnetic block 9 is installed into the mounting groove 8 in the magnetic metal connecting plate 7. The magnetic block 9 and the leaf spring 10 connect two adjacent connecting plates 7. After the connection is completed, under the action of the leaf spring 10, the mesh plate 4 on one of the connecting plates 7 can abut against the column 3 on the adjacent connecting plate 7. Under the action of seawater buoyancy, the first float 5 and the second float 6 move upward. The first float 5 pulls the connecting belt 14. Under the guidance of the guide block 15, the connecting belt 14 pulls the pressure block 12 downward. When the pressure block 12 moves downward, it will press the leaf spring 10 and the magnetic blocks 9 on both sides, ensuring that the two adjacent connecting plates 7 remain fixed after connection. The device can change the vertical or horizontal state of the baffle 18 by adjusting the component 17. When the baffle 18 is horizontal, the top of the outer shell 1 is closed to facilitate the subsequent collection of fish feces. When collecting feces, the turntable 25 is rotated. The turntable 25 acts on the docking component 19 through the third connecting plate 21 and the second connecting plate 20. The docking component 19 can close the top of the outer shell 1 a second time and release the locking state between the outer shell 1 and the connecting shell 2.

[0035] like Figures 3-12As shown, by extending or shortening the electric push rod 1704, the first connecting plate 1705 is driven to slide within the support plate 1701, thereby causing the pressure plate 1707 to slide. At the same time, the first spring 1706 causes the pressure plate 1707 to abut against the rubber roller 1702, causing the rubber roller 1702 to drive the rotating rod 1703 and the baffle 18 to rotate, so as to adjust the vertical or horizontal state of the baffle 18. After the baffle 18 is adjusted to the horizontal state, the top of the outer shell 1 can be sealed, so that the outer shell 1 and the connecting shell 2 are isolated before the device collects feces. Rotate turntable 25 until it is collinear with the central axis of outer shell 1. Turntable 25 abuts against third connecting plate 21 through oblique surface 24, causing third connecting plate 21 to drive second connecting plate 20 to move upward. Second connecting plate 20 pulls traction steel rope 1906. Under the guidance of first guide wheel 1907 and second guide wheel 1908, traction steel rope 1906 pulls slide plate 1905 until slide plate 1905 disengages from second connecting block 1904. Second spring 1903 on slide plate 1905 is compressed. At this time, after the top of outer shell 1 is closed twice by turntable 25, the function of separating outer shell 1 from bottom of connecting shell 2 can be realized, so as to recover the collected fish feces in the closed state.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
