Description

Technical Field

[0001] The present invention relates to the technical field of laver cultivation, and specifically relates to a liftable laver cultivation raft frame for improving water quality. Background Art

[0002] As a popular seafood product, laver has a large and stable market demand. Whether it is fresh laver or various processed products such as dried laver and flavored laver snacks, they all have good sales performance in the market and possess relatively high economic value.

[0003] Traditional semi-floating raft cultivation controls the lifting and lowering of floating barrels through limit blocks. Although it can achieve the exposure of laver at low tide, it misses the opportunity to enhance disease resistance and improve quality by actively lifting the laver above the sea surface during the high tide period (such as at noon with strong sunlight); Therefore, to meet the growth requirements of laver, it is required to be able to drive the laver above the sea surface for exposure and drying through a lifting component during high tide. This means driving the floating barrel above the sea surface. However, the tidal phenomenon causes the highest water level of the sea surface to change regularly in height every day, and there are differences in the sea surface height every day. If the sea surface height tomorrow is higher than today's, the floating barrel will be submerged in sea water under the block of the lifting component, and the buoyancy will increase accordingly. If the lifting component is not adjusted in time to make the floating barrel return to the sea surface, the increased buoyancy will act on the lifting component in the opposite direction, causing damage to the component. But if the lifting component is adjusted every time to make the floating barrel return to the sea surface, it is necessary to frequently adjust it daily according to the tidal changes, which makes the cultivation process extremely complicated. Based on this, the present invention purposefully provides a liftable laver cultivation raft frame for improving water quality that can adapt to tidal changes and ensure that laver can be exposed and dried under various tidal conditions. Summary of the Invention

[0004] The purpose of the present invention is to provide a liftable laver cultivation raft frame for improving water quality in view of the deficiencies of the prior art, so as to solve the technical problems in the prior art.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A liftable laver cultivation raft frame for improving water quality, comprising: Vertical frames, four vertical frames are arranged in a square layout. A connecting block is slidably installed in each vertical frame. A floating barrel is fixedly installed at the bottom of the connecting block. Adjacent connecting blocks are connected by a cable. A plurality of uniformly distributed net curtains for cultivating laver are connected between two symmetrically arranged cables. A limit block is fixedly installed on each vertical frame; A fixing frame is arranged on one side of the vertical frame. A square frame is slidably installed on the fixing frame. The square frame is driven by a built-in driving source on the fixing frame to lift, and the square frame is located above the sea surface. Lift columns are fixedly installed at the four corners of the square frame. Each lift column corresponds to a vertical frame. A telescopic frame is slidably installed on the lift column. The telescopic frame is driven by a driving component to move, and the telescopic frame is located between the limit block and the connecting block. When the driving source drives the square frame to descend so that the lift column is in the initial position, the telescopic frame is located inside the lift column at this time; when the driving source drives the square frame to ascend, the lift column ascends synchronously and drives the telescopic frame to fully extend through the driving component. At this time, one end of the telescopic frame moves into the vertical frame, and when the lift column ascends, it drives the connecting block to ascend synchronously through the telescopic frame. And when the height of the rising tide of the sea is the lowest, the telescopic frame is fully extended at this time, and the telescopic frame is always located below the connecting block.

[0006] As a further scheme of the present invention: The driving component includes a round block, a waist-shaped groove, a lifting plate, an inclined groove and a linkage component. The linkage component is arranged inside the lift column, and the linkage component is connected to the vertical frame. The lifting plate is slidably installed inside the lift column. The lifting plate is driven by the linkage component to lift. The inclined groove is opened on the lifting plate, and the horizontal height of one end of the inclined groove close to the vertical frame is lower than the horizontal height of the end of the inclined groove far from the vertical frame. The waist-shaped groove is opened inside the lift column, and the waist-shaped groove corresponds to the inclined groove. The round block is slidably installed in the waist-shaped groove. The round block is fixedly connected to the telescopic frame. The round block is slidably installed in the inclined groove. When the square frame drives the lift column to rise, the lift column drives the lifting plate to rise through the linkage component. When the square frame drives the lift column to descend, the lift column drives the lifting plate to descend through the linkage component.

[0007] As a further scheme of the present invention: The linkage component includes a gear, a driven rack plate and a fixed rack plate. The fixed rack plate is fixedly installed on the vertical frame, and the fixed rack plate is always located above the sea surface. A second cavity is opened inside the lift column. The gear is rotatably installed in the second cavity. The driven rack plate is slidably installed in the second cavity, and the driven rack plate is fixedly connected to the top end of the lifting plate. The gear is located between the driven rack plate and the fixed rack plate, and the gear meshes with the driven rack plate. When the lift column rises and falls, when the gear passes through the fixed rack plate, the gear meshes with the fixed rack plate.

[0008] As a further scheme of the present invention: A clamping hole is opened on the lifting plate. A first cavity and an installation hole are opened inside the bottom end of the lift column. The first cavity is communicated with the installation hole. The lifting plate is slidably installed in the first cavity. A clamping block is connected to the installation hole through a spring. When the lift column rises to make the telescopic frame fully extended, the pre-tightening force of the spring pushes the clamping block into the first cavity. At this time, the clamping block abuts against the bottom of the lifting plate. When the lift column is in the initial position, the clamping hole is aligned with the installation hole. At this time, the pre-tightening force of the spring pushes the clamping block into the clamping hole.

[0009] As a further solution of the present invention: a trapezoidal block is fixedly installed on the vertical frame, the trapezoidal block is arranged vertically, one end of the clamping block is fixedly installed with a connecting rod, the connecting rod is slidably connected with the lifting column, one end of the connecting rod is rotatably installed with a rotating cylinder, the rotating cylinder is in rolling contact with the surface of the trapezoidal block. When the lifting column is in the initial position, the rotating cylinder is located below the trapezoidal block. When the lifting column rises, the rotating cylinder cooperates with the lower hypotenuse of the trapezoidal block to pull the connecting rod so that the clamping block contracts from the clamping hole into the installation hole. At this time, the gear is located below the fixed rack plate. Subsequently, when the lifting column rises to make the gear mesh with the fixed rack plate, the rotation of the gear drives the driven rack plate and the lifting plate to rise, so that the telescopic frame is fully extended. As the lifting column continues to rise, the rotating cylinder cooperates with the upper hypotenuse of the trapezoidal block. At this time, the pre-tightening force of the spring pushes the clamping block into the first cavity.

[0010] As a further solution of the present invention: a lifting frame is provided on each lifting column, one end of the lifting frame is located inside the vertical frame and above the connecting block at this end. When the square frame descends and the lifting column moves downward from the initial position, the lifting frame abuts against the connecting block and presses the connecting block into the sea water.

[0011] As a further solution of the present invention: the lifting frame is slidably installed on the lifting column, and each lifting frame is driven by an output source inside the lifting column to perform lifting movement. When the output source drives the lifting frame to descend, the lifting frame abuts against the connecting block and presses the connecting block into the sea water.

[0012] As a further solution of the present invention: a plurality of aeration pipes arranged at equal intervals are communicated with the bottom of the fixed frame, and the aeration pipes are connected with an external aeration assembly.

[0013] The beneficial effects of the present invention: 1. In the present invention, the telescopic movement of the telescopic frame can be driven by the lifting of the lifting column, and the rising of the lifting column drives the connecting block to rise synchronously through the telescopic frame. Such a setting can actively lift the connecting block through the telescopic frame during the high tide period, so that the laver can be exposed above the sea surface, realizing the drying and sun exposure of the laver during the high tide period. And when the height of the rising sea tide is the lowest, the telescopic frame is fully extended at this time, and the telescopic frame is always located below the connecting block. Such a setting enables the floating barrel and the connecting block to freely rise and fall with the tides throughout the year, avoiding the problem that the floating barrel and the connecting block are forced to be immersed in the sea water due to the obstruction of the lifting assembly, resulting in an increase in buoyancy and a reaction force on the lifting assembly, causing damage to the assembly; 2. In the present invention, by providing a lifting frame on the lifting column, when the square frame descends and the lifting column moves downward from the initial position, the lifting frame abuts against the connecting block and presses the connecting block into the sea water, allowing the laver to fully absorb the nutrients in the sea water, and the movement of the net curtain driving the laver can also break the stratification of the sea water, promoting the mixing of the surface sea water rich in dissolved oxygen and the deep sea water rich in nutrient salts, creating a suitable environment for the growth of the laver; 3. In the present invention, the external aeration assembly cooperates with the aeration pipe to aerate below the laver, which can directly and effectively increase the dissolved oxygen content in seawater, meet the breathing needs of laver and other marine organisms, maintain a good living environment. Moreover, the nutrient substances in seawater are unevenly distributed, and the water flow generated by the aeration of the aeration pipe can drive the seawater to flow, so that the nutrient substances around the laver are fully mixed and circulated.

Detailed Embodiment

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-9 as shown in the figure, the present invention is a liftable laver cultivation raft for improving water quality, comprising: Vertical frames 1, four vertical frames 1 are arranged in a square, a connecting block 3 is slidably installed in each vertical frame 1, a floating cylinder 2 is fixedly installed at the bottom of the connecting block 3, adjacent two connecting blocks 3 are connected by a cable 4, a plurality of uniformly distributed net curtains for cultivating laver are connected between two symmetrically arranged cables 4, and a limiting block 5 is fixedly installed on each vertical frame 1; A fixing frame 6, which is arranged on one side of the vertical frame 1, a square frame 8 is slidably installed on the fixing frame 6, the square frame 8 is driven by a driving source inside the fixing frame 6 to lift, and the square frame 8 is located above the sea surface, lifting columns 9 are fixedly installed at the four corners of the square frame 8, each lifting column 9 corresponds to a vertical frame 1, a telescopic frame 10 is slidably installed on the lifting column 9, the telescopic frame 10 is driven by a driving component to move, and the telescopic frame 10 is located between the limiting block 5 and the connecting block 3. When the driving source drives the square frame 8 to descend so that the lifting column 9 is in the initial position, at this time the telescopic frame 10 is located inside the lifting column 9; when the driving source drives the square frame 8 to rise, the lifting column 9 rises synchronously and drives the telescopic frame 10 to fully extend through the driving component. At this time, one end of the telescopic frame 10 moves into the vertical frame 1, and when the lifting column 9 rises, it drives the connecting block 3 to rise synchronously through the telescopic frame 10, and when the height of the rising tide of the sea surface is the lowest, at this time the telescopic frame 10 is fully extended, and the telescopic frame 10 is always located below the connecting block 3.

[0019] In one case of this embodiment, the driving source can be selected from components such as electric telescopic rods, electric cylinders, screw rod assemblies driven by motors, etc., and other mechanisms capable of realizing lifting movement can also be selected. This embodiment does not make specific limitations here.

[0020] The working principle of the present invention: as Figure 2 shown as an example, the connecting blocks 3 in the four vertical frames 1 are connected by cables 4, and then net curtains are connected into a grid shape on the cables 4 enclosing a square, and laver is planted on the net curtains. The floating cylinders 2 float on the sea surface, and the laver on the net curtains is immersed in sea water. Due to the action of tidal force, the sea water rises and falls periodically, and the floating cylinders 2 always float on the sea surface. However, limiting blocks 5 are arranged in the vertical frames 1. When the ebb tide occurs, the connecting block 3 descends to the limiting block 5 and is blocked by the limiting block 5, and the connecting block 3 will not descend. As the sea water continues to descend, the laver on the net curtain will be exposed above the sea surface, and finally the laver is completely above the sea surface, so as to carry out dry exposure or sun exposure, effectively supplementing light to promote the growth of laver, and sun exposure helps to kill some germs, parasites and harmful algae attached to the surface of laver, reducing the disease probability of laver; Considering that the time with the best solar exposure effect overlaps with the high tide period, a fixed frame 6 is provided. A liftable square frame 8 is provided on the fixed frame 6. When the square frame 8 rises, it can drive the lifting column 9 to rise synchronously. When the lifting column 9 rises, it drives the telescopic frame 10 to fully extend through the driving component. At this time, one end of the telescopic frame 10 moves into the vertical frame 1. Subsequently, when the lifting column 9 rises, it drives the connecting block 3 to rise synchronously through the telescopic frame 10. Such a setting can actively lift the connecting block 3 through the telescopic frame 10 during the high tide period, so that the laver can be exposed above the sea surface, realizing the dry exposure and solar exposure of the laver during the high tide period. When the driving source drives the square frame 8 to descend so that the lifting column 9 is in the initial position, at this time the telescopic frame 10 is located inside the lifting column 9, and at this time the telescopic frame 10 will not prevent the floating cylinder 2 and the connecting block 3 from rising and falling with the tide; More critically, when the height of the rising tide on the sea surface is the lowest, at this time the telescopic frame 10 is fully extended, and the telescopic frame 10 is always located below the connecting block 3. This means that at any time, when the floating cylinder 2 and the connecting block 3 rise and fall with the tide, there is one day in a year in this laver cultivation area when the height of the rising tide on the sea surface is the lowest. And on this day, when the lifting column 9 rises and drives the telescopic frame 10 to fully extend through the driving component, the telescopic frame 10 is still located below the connecting block 3. In this way, the connecting block 3 can always be driven to rise by the rising of the lifting column 9 and the telescopic frame 10, so as to expose the laver to the sun and dry it during the high tide period. With such a setting, the floating cylinder 2 and the connecting block 3 can rise and fall freely with the tide throughout the year, avoiding the problem that the floating cylinder 2 and the connecting block 3 are forced to immerse in the sea water due to the obstruction of the lifting component, resulting in an increase in buoyancy and a reaction force on the lifting component, causing damage to the component.

[0021] As Figures 1-7 shown, as a preferred embodiment of the present invention, the driving component includes a round block 1001, a waist-shaped groove 903, a lifting plate 14, an inclined groove 1401 and a linkage component. The linkage component is arranged inside the lifting column 9 and is connected to the vertical frame 1. The lifting plate 14 is slidably installed inside the lifting column 9, and the lifting plate 14 is driven to rise and fall by the linkage component. The inclined groove 1401 is opened on the lifting plate 14, and the horizontal height of one end of the inclined groove 1401 close to the vertical frame 1 is lower than the horizontal height of the other end of the inclined groove 1401 far from the vertical frame 1. The waist-shaped groove 903 is opened inside the lifting column 9, and the waist-shaped groove 903 corresponds to the inclined groove 1401. The round block 1001 is slidably installed in the waist-shaped groove 903. The round block 1001 is fixedly connected to the telescopic frame 10, and the round block 1001 is slidably installed in the inclined groove 1401. When the square frame 8 drives the lifting column 9 to rise, the lifting column 9 drives the lifting plate 14 to rise through the linkage component. When the square frame 8 drives the lifting column 9 to descend, the lifting column 9 drives the lifting plate 14 to descend through the linkage component.

[0022] In practical application of this embodiment, when the square frame 8 drives the lifting column 9 to rise, the lifting column 9 drives the lifting plate 14 to rise through the linkage assembly. The rising of the lifting plate 14 causes the round block 1001 to slide in the inclined groove 1401. Due to the limitation of the waist-shaped groove 903, the round block 1001 will move in the waist-shaped groove 903 towards the direction close to the vertical frame 1, so that one end of the telescopic frame 10 moves into the vertical frame 1. Subsequently, when the lifting column 9 rises, the telescopic frame 10 abuts against the bottom of the connecting block 3, realizing the active rising of the connecting block 3. On the contrary, when the square frame 8 drives the lifting column 9 to descend, the lifting column 9 drives the lifting plate 14 to descend through the linkage assembly. The floating cylinder 2 and the connecting block 3 will descend under the action of gravity. The descending of the lifting plate 14 causes the telescopic frame 10 to contract into the lifting column 9, avoiding hindering the descending of the floating cylinder 2 and the connecting block 3.

[0023] As Figures 1-7 shown, as a preferred embodiment of the present invention, the linkage assembly includes a gear 11, a driven rack plate 12 and a fixed rack plate 13. The fixed rack plate 13 is fixedly installed on the vertical frame 1 and is always above the sea surface. A second cavity 902 is formed in the lifting column 9. The gear 11 is rotatably installed in the second cavity 902. The driven rack plate 12 is slidably installed in the second cavity 902 and is fixedly connected to the top end of the lifting plate 14. The gear 11 is located between the driven rack plate 12 and the fixed rack plate 13 and meshes with the driven rack plate 12. When the lifting column 9 moves up and down, when the gear 11 passes by the fixed rack plate 13, the gear 11 meshes with the fixed rack plate 13.

[0024] In practical application of this embodiment, the fixed rack plate 13 is fixedly installed on the vertical frame 1. As Figure 7 shown for example, when the lifting column 9 rises, the gear 11 will pass by the fixed rack plate 13. At this time, the gear 11 meshes with the fixed rack plate 13, and the gear 11 will rotate counterclockwise. Since the gear 11 meshes with the driven rack plate 12, the gear 11 will drive the driven rack plate 12 to rise, and the lifting plate 14 rises synchronously with the driven rack plate 12, thus achieving the purpose of fully extending the telescopic frame 10. After the gear 11 rises away from the fixed rack plate 13, it stops rotating until the lifting column 9 descends. As Figure 5 shown for example, at this time the gear 11 descends and passes by the fixed rack plate 13, and the gear 11 will rotate clockwise, thereby driving the driven rack plate 12 to descend, and the lifting plate 14 descends synchronously with the driven rack plate 12, thus achieving the purpose of contracting the telescopic frame 10 into the lifting column 9. In this way, the automatic telescoping process of the telescopic frame 10 during the up and down movement of the lifting column 9 can be realized without an additional power source.

[0025] As Figures 1-8As shown, as a preferred embodiment of the present invention, a clamping hole 1402 is provided on the lifting plate 14. An inner bottom end of the lifting column 9 is provided with a first cavity 901 and a mounting hole 15. The first cavity 901 communicates with the mounting hole 15. The lifting plate 14 is slidably mounted in the first cavity 901. A clamping block 16 is connected in the mounting hole 15 through a spring 17. When the lifting column 9 rises and the telescopic frame 10 is fully extended, the pre-tightening force of the spring 17 pushes the clamping block 16 into the first cavity 901. At this time, the clamping block 16 abuts against the bottom of the lifting plate 14. When the lifting column 9 is in the initial position, the clamping hole 1402 is aligned with the mounting hole 15. At this time, the pre-tightening force of the spring 17 pushes the clamping block 16 into the clamping hole 1402.

[0026] In one case of this embodiment, one end of the clamping block 16 is always located in the mounting hole 15.

[0027] In actual application of this embodiment, considering the problem that after the lifting column 9 rises and the gear 11 moves away from the fixed rack plate 13, at this time the lifting plate 14 supports the connecting block 3 to rise, and the weight of the laver may cause the lifting plate 14 to descend, so that the telescopic frame 10 retracts back into the lifting column 9 again. Therefore, the clamping block 16 is provided. When the lifting column 9 rises and the telescopic frame 10 is fully extended, the pre-tightening force of the spring 17 pushes the clamping block 16 into the first cavity 901. At this time, the clamping block 16 abuts against the bottom of the lifting plate 14, preventing the lifting plate 14 from descending, ensuring that the telescopic frame 10 can support the connecting block 3 to rise, and achieving the purpose of drying and sun-exposing the laver during the high tide period. And when the lifting column 9 is in the initial position, the clamping hole 1402 is aligned with the mounting hole 15. At this time, the pre-tightening force of the spring 17 pushes the clamping block 16 into the clamping hole 1402. In this way, it can also prevent the lifting plate 14 from rising, so that when the lifting column 9 is in the initial position, the telescopic frame 10 is always located in the lifting column 9.

[0028] As Figures 1-9As shown, as a preferred embodiment of the present invention, a trapezoidal block 20 is fixedly installed on the vertical frame 1. The trapezoidal block 20 is arranged vertically. One end of the clamping block 16 is fixedly installed with a connecting rod 18. The connecting rod 18 is slidably connected to the lifting column 9. One end of the connecting rod 18 is rotatably installed with a rotating cylinder 19. The rotating cylinder 19 is in rolling contact with the surface of the trapezoidal block 20. When the lifting column 9 is in the initial position, the rotating cylinder 19 is located below the trapezoidal block 20. When the lifting column 9 rises, the rotating cylinder 19 cooperates with the lower inclined side of the trapezoidal block 20 to pull the connecting rod 18 so that the clamping block 16 retracts from the clamping hole 1402 into the installation hole 15. At this time, the gear 11 is located below the fixed rack plate 13. Subsequently, when the lifting column 9 rises to make the gear 11 mesh with the fixed rack plate 13, the rotation of the gear 11 drives the driven rack plate 12 and the lifting plate 14 to rise, so that the telescopic frame 10 is fully extended. As the lifting column 9 continues to rise, the rotating cylinder 19 cooperates with the upper inclined side of the trapezoidal block 20. At this time, the pre-tightening force of the spring 17 pushes the clamping block 16 into the first cavity 901.

[0029] In actual application of this embodiment, when the lifting column 9 rises, the rotating cylinder 19 cooperates with the lower inclined side of the trapezoidal block 20 to pull the connecting rod 18 so that the clamping block 16 retracts from the clamping hole 1402 into the installation hole 15. At this time, the gear 11 is located below the fixed rack plate 13. In this way, it is avoided that when the clamping block 16 still restricts the lifting and lowering of the lifting plate 14, the gear 11 and the fixed rack plate 13 are already meshed, resulting in the problem of movement interference between the rising of the lifting column 9 and the rising of the driven rack plate 12. Subsequently, when the lifting column 9 rises to make the gear 11 mesh with the fixed rack plate 13, the rotation of the gear 11 drives the driven rack plate 12 and the lifting plate 14 to rise, so that the telescopic frame 10 is fully extended. As the lifting column 9 continues to rise, the rotating cylinder 19 cooperates with the upper inclined side of the trapezoidal block 20. At this time, the pre-tightening force of the spring 17 pushes the clamping block 16 into the first cavity 901, so as to realize that the clamping block 16 abuts against the bottom of the lifting plate 14 to prevent the lifting plate 14 from descending; Conversely, when the laver is exposed to the air and sun-dried, when the lifting column 9 descends, the clamping block 16 will first move from the first cavity 901 to the installation hole 15, and then the gear 11 will be engaged with the fixed rack plate 13, so that the driven rack plate 12 and the lifting plate 14 descend. When the lifting plate 14 descends to the bottom, that is, the telescopic frame 10 is completely retracted into the lifting column 9. At this time, the clamping hole 1402 is aligned with the installation hole 15, so that the clamping block 16 is inserted into the clamping hole 1402 to restrict the movement of the lifting plate 14.

[0030] As Figures 1-9 shown, as a preferred embodiment of the present invention, a lifting frame 21 is provided on each lifting column 9. One end of the lifting frame 21 is located inside the vertical frame 1 and above the connecting block 3 at this end. When the square frame 8 descends and the lifting column 9 moves downward from the initial position, the lifting frame 21 abuts against the connecting block 3 and presses the connecting block 3 into the sea water.

[0031] In actual application of this embodiment, considering the stratification of seawater and the different nutrients in different seawater layers, if the buoy 2 always floats on the sea surface, the laver cultured on the cable 4 on the net curtain can only float on the upper layer of seawater, then there is a problem of low absorption and utilization rate of nutrients in seawater by laver. Therefore, a lifting frame 21 is provided on the lifting column 9. When the square frame 8 descends and the lifting column 9 moves downward from the initial position, the lifting frame 21 abuts against the connecting block 3 and presses the connecting block 3 into the seawater, so that the laver can fully absorb the nutrients in the seawater. The movement of the laver driven by the net curtain can also break the stratification of the seawater, promote the blending of the surface seawater rich in dissolved oxygen and the deep seawater rich in nutrients, and create an environment suitable for the growth of laver.

[0032] like Figures 1-9 As shown, as a preferred embodiment of the present invention, the lifting frame 21 is slidably installed on the lifting column 9, and each lifting frame 21 is driven by the output source built into the lifting column 9 to perform lifting movement. When the output source drives the lifting frame 21 to descend, the lifting frame 21 abuts against the connecting block 3 and presses the connecting block 3 into the seawater.

[0033] In one case of this embodiment, the output source may be an electric telescopic rod, a motor-driven threaded rod assembly, or other mechanisms capable of achieving lifting motion, which is not specifically limited in this embodiment.

[0034] In actual application, the lifting and lowering of the lifting frame 21 is directly controlled by the output source, and there is no need to lift the square frame 8, and there is no need to continue to move the lifting column 9 downward from the initial position to drive the connecting block 3 to be immersed in seawater. In this way, the lifting and lowering of the lifting column 9 is specifically used to control the connection block 3 to rise to the sea surface to expose the cultured laver, and the lifting and lowering of the lifting frame 21 is specifically used to control the connection block 3 to be immersed in seawater, so that the cultured laver is located in different seawater layers and repeatedly absorbs nutrients in the seawater, so that the lifting column 9 and the lifting frame 21 can focus on specific functions and improve the stability of operation.

[0035] like Figure 1 As shown, as a preferred embodiment of the present invention, the bottom of the fixing frame 6 is connected to a plurality of aeration pipes 7 arranged at equal intervals, and the aeration pipes 7 are connected to an external aeration component.

[0036] In one case of this embodiment, it should be noted that the external aeration assembly described in the present invention includes an air compressor, a gas pipeline, a valve and a control system, etc. The above components are all prior arts, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0037] In practical application of this embodiment, the photosynthesis of laver consumes carbon dioxide in seawater and releases oxygen. However, when it is night or the light is insufficient, the dissolved oxygen in the water body will gradually decrease. By using the external aeration component to cooperate with the aeration pipe 7 to aerate below the laver, the dissolved oxygen content in seawater can be directly and effectively increased, meeting the breathing needs of laver and other marine organisms, maintaining a good living environment. Moreover, the distribution of nutrients in seawater is not uniform, and the water flow generated by the aeration of the aeration pipe 7 can drive the seawater to flow, enabling the nutrients around the laver to be fully mixed and circulated.

[0038] The above has described in detail one embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
