Description

Technical Field

[0001] This invention belongs to the field of seagrass bed ecosystem protection and restoration, specifically relating to a device and method for underwater seagrass block collection and transplantation restoration. Background Technology

[0002] Seagrass beds, as an important component of the marine ecosystem, have irreplaceable ecological functions and are known as the "lungs of the ocean" and "blue carbon sink." They not only fix large amounts of carbon dioxide through photosynthesis, making them a significant contributor to marine carbon sequestration, but also provide habitats, feeding grounds, and breeding grounds for marine life such as fish, shrimp, and shellfish, maintaining marine biodiversity. Furthermore, seagrass' extensive root system effectively stabilizes the seabed, mitigates the impact of waves, and plays a vital role in preventing erosion and protecting the coastline, thus being crucial for maintaining marine ecological balance.

[0003] Human activities in the ocean are intensifying, with increased fishing activity impacting seagrass beds. In some areas, seagrass has significantly degraded due to human activity, necessitating artificial restoration. Because small and medium-sized seagrass plants are small and fragile, individual transplantation is not suitable. Currently, the best artificial restoration method for small and medium-sized seagrass is the block transplantation method, which involves transplanting seagrass along with the seabed sediment in the form of blocks to the area requiring restoration.

[0004] In some areas of the South my country Sea with good water quality and high transparency, seagrass can be distributed at greater depths. For example, in the Xisha Islands region of South my country Sea, where water quality is good and transparency is high, seagrass can be found at depths of over 40 meters. However, for seagrass distributed underwater, there is currently a lack of seagrass transplantation and restoration devices that can ensure the integrity of the seagrass substrate during underwater harvesting and transplantation, preventing it from being washed away by currents. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a device and method for underwater seagrass block collection, transplantation and repair, which can ensure that the seagrass substrate remains intact and is not washed away by the water flow when seagrass blocks are collected and transplanted underwater.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A device for underwater seagrass block collection, transplantation and restoration includes a box, a box cover and a mud pusher;

[0008] The side and top surfaces of the box are respectively provided with side openings and top openings. The side of the box is provided with a plurality of locking mechanisms, and the plurality of locking mechanisms correspond to the edges of the side openings and top openings respectively.

[0009] The mud pusher is used to shovel holes or push grass blocks;

[0010] The box cover includes a top cover and side covers. The top cover is hinged to the edge of the top opening via a hinge, and covers the top opening when the top cover is closed. The side covers are hinged to the edge of the top cover via a hinge, and cover the side opening when both side covers are closed. When the top cover and / or side covers are closed, the locking mechanism is detachably connected to the top cover and / or side covers.

[0011] Furthermore, the mud pusher includes a mud pusher blade with a blade-shaped opening and a gripping rod fixedly connected to it.

[0012] Furthermore, the box body is cuboid in shape, the side opening is inclined, the side cover is triangular in shape, the end face of the side cover is triangular, and the edge of the side cover opening located between the two end faces is hinged to the top cover via a hinge. The hinge axis between the side cover and the top cover is located on the side of the side cover away from the box body. The locking mechanism consists of two sets symmetrically distributed on both sides of the box body. Each set of the locking mechanism includes a side lock and a top lock. The side lock is located near the edge of the side opening, and the side lock latch is connected to a side latch. The side latch is fixedly located on the inclined edge of the end face of the side cover. The top lock is located near the edge of the top opening, and the top lock latch is connected to a top latch. The top latch is fixedly located on the right-angled edge of the end face of the side cover. When the top cover is closed, the side cover is opened and overlapped on the top cover. The top lock and the top latch are latched together to fix the top cover and the side cover and open the side opening.

[0013] Furthermore, the box body is cuboid in shape, the side opening is inclined, the side cover is triangular in shape, the end face of the side cover is triangular, and the edge of the side cover opening located between the two end faces is hinged to the top cover via a hinge. The hinge axis between the side cover and the top cover is located on the side of the side cover away from the box body. The locking mechanism includes two sets of holes on both sides of the box body, the hole sets including a first hole and a second hole. A connecting rod is provided on the end face of the side cover. One end of the connecting rod is provided with a vertical part, which is rotatably connected to the end face of the side cover. The other end of the connecting rod is provided with a connecting hook. When both the side cover and the top cover are closed, the connecting hook is inserted into the first hole, and the connecting rod restricts the opening of the side cover and the top cover. When the top cover is closed and the side cover is opened and overlapped on the top cover, the connecting hook is inserted into the second hole, and the connecting rod restricts the opening of the top cover.

[0014] Furthermore, when the top cover is in the closed state, the hinge axis between the top cover and the housing is the first hinge axis, and the hinge axis between the side cover and the top cover is the second hinge axis; the length of the connecting rod is less than the distance between the first hole and the second hinge axis, and the distance between the first hole and the second hinge axis is less than the distance between the first hole and the first hinge axis.

[0015] Furthermore, the connecting hook is rotatably connected to the end of the connecting rod, and both the first hole and the second hole are strip-shaped. The connecting hook is inserted into the first hole or the second hole by rotation.

[0016] Furthermore, a filter screen is provided on the inner side of the box; a handle is provided on the side of the box.

[0017] A method for collecting and transplanting seagrass clumps for underwater restoration, employing the aforementioned device for collecting and transplanting seagrass clumps for underwater restoration, includes the following methods:

[0018] Step 1: Take the container to the seaweed collection area. Use a mud shovel to dig a pit in the seaweed growth area large enough to accommodate the bottom of the container. Then open the side cover, allowing it to overlap the top cover. Lock the side cover and top cover using the locking mechanism to open the side opening. Place the container in the pit and push it forward along the side opening to shovel seaweed and substrate into the container until it has moved one container length. Release the locking mechanism, then replace the side cover and use the locking mechanism to secure the side cover and top cover. Gently remove the container from the water. During removal, some water will drain from the filter screen to reduce weight.

[0019] Step Two: Transfer the container to the seaweed restoration area. First, use a mud pusher to dig a pit in the seaweed restoration area large enough to accommodate the bottom of the container. Then, place the container in the pit and open the side cover, allowing it to overlap the top cover. Lock the side cover and top cover using the locking mechanism to open the side opening. Next, insert a mud pusher into the innermost part of the container to help push the seaweed blocks outward. Then, pull the container out of the pit, simultaneously pushing the seaweed blocks into the pit with the mud pusher to ensure the seaweed roots are fully extended. Then, backfill the pit with substrate and compact it to ensure close contact between the seaweed roots and the substrate.

[0020] Furthermore, in step one, after removing the container from the water, the container is placed in a plastic basket containing a small amount of seawater, and then the plastic basket and the container are transferred together to the seaweed restoration area. The transportation time must be controlled within 2 hours to ensure the freshness of the seaweed seed source.

[0021] The present invention has the following beneficial effects:

[0022] The underwater seagrass block collection and transplantation restoration device of the present invention is mainly applicable to the collection and transplantation restoration of small and medium-sized seagrass blocks distributed underwater. By flipping the side cover and / or top cover, a side opening or lateral and top opening can be opened. When the lateral opening is opened, the seagrass and corresponding substrate in the collection area can be shoveled into the box through the side opening. When the side and top openings are opened, a mud pusher can be fully extended into the box, facilitating the pushing of seagrass blocks outwards. Simultaneously, the box can be moved relative to the seagrass block, thereby improving the efficiency of shoveling out the seagrass block. Using the underwater seagrass block collection and transplantation restoration device and method of the present invention, the morphology of the seagrass substrate can be maintained during underwater seagrass block collection and transplantation, and it cannot be dispersed by water currents.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Terms such as “upper,” “inner,” “middle,” “left,” “right,” and “one” used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0030] Example 1

[0031] A device suitable for underwater seagrass harvesting and transplantation repair, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it includes a box body 1, a box cover, and a mud pusher; the side and top surfaces of the box body 1 are respectively provided with side openings 11 and top openings 12, and the mud pusher is used to shovel holes or push grass blocks; the box cover is movably connected to the box body 1, and the box cover opens or closes the side openings 11 and top openings 12; the box body 1 is provided with a locking mechanism 4, which is used to fix the box cover in the closed state.

[0032] In this embodiment, the box body 1 is rectangular, the side opening 11 of the box body 1 is inclined, the box cover includes a top cover 3 and a side cover 2, the edge of the top cover 3 is hinged to the edge of one end of the top opening 12 by a hinge, and the top cover 3 covers the top opening 12 when closed.

[0033] The side cover 2 is in the shape of a triangular prism, and the end face of the side cover 2 is a right triangle. One side of the side cover 2 is the opening. One edge of the opening of the side cover 2 located between the two end faces is hinged to the edge of the top cover 3. The hinge axis between the side cover 2 and the top cover 3 is located on the side of the top cover 3 away from the box body 1. The two end faces of the side cover 2 are coplanar with the two side faces of the box body 1 respectively. When both the top cover 3 and the side cover 2 are closed, the top cover 3 and the side cover 2 cover the top opening 12 and the side opening 11 respectively.

[0034] The locking mechanism 4 consists of two sets symmetrically distributed on both sides of the housing 1. Each set of locking mechanism 4 includes a side lock 41 and a top lock 42.

[0035] The side lock 41 is fixed to the edge of the side of the box 1 near the side opening 11 by screws or welding. The side lock 41 is connected to the side lock buckle 411, which is fixed to the beveled edge of the end face of the side cover 2 by screws or welding. When the top cover 3 and the side cover 2 are both closed, the side lock 41 and the side lock buckle 411 are corresponding and locked together, thereby fixing the side cover 2 and the top cover 3 in the closed state.

[0036] The top lock 42 is fixed to the edge of the side of the housing 1 near the top opening 12 by screws or welding. The top lock 42 is connected to a top lock buckle 421, which is fixed to the right-angled edge of the side cover 2 by screws or welding. When the top cover 3 is closed and the side cover 2 is open and overlaps the top cover 3, the top lock 42 and the top lock buckle 421 are aligned and locked together to fix the top cover 3 in the closed and side cover 2 in the open state. Therefore, the dragging of the lid can be reduced when moving the box 1. At the same time, the top cover 3 and the box 1 can form a barrel shape with only the side opening 11 in the open state. This can keep the inside of the box 1 in a relatively closed state. When the seaweed block is placed into the box 1, the influence of the external water flow on the water flow inside the box 1 can be reduced, thereby reducing the rolling of the seaweed block plant roots with the substrate. This stabilizes the water flow inside the box 1 and keeps the seaweed block plant roots in close contact with the substrate.

[0037] It should be noted that both the side lock 41 and the top lock 42 are conventional lock structures in the prior art, and can be detachably engaged with the latch through a latch connection method.

[0038] Multiple filter screens 14 are installed along the length of the side of the box 1. The filter screens 14 are located at the top of the side of the box 1. When the box 1 containing seaweed blocks is transported smoothly, the water at the top of the box 1 can be drained through the filter screens 14 to reduce the overall weight of the box 1 and facilitate transportation. Meanwhile, the water at the bottom of the box 1 remains inside the box 1 to maintain the growth environment of the seaweed blocks.

[0039] Handles 13 are welded and fixed to both opposite sides of the box body 1, so that the box body 1 can be transported smoothly by grasping the handles 13 by hand, thereby improving transportation efficiency.

[0040] In this embodiment, the mud pusher includes a mud pusher 5. The blade of the mud pusher 5 is a flat cutting edge. The mud pusher 5 is fixedly connected to a gripping rod 51 so that the user can hold the gripping rod 51 and use the mud pusher 5 to scoop out seaweed clumps and put them into the box 1 through the side opening 11.

[0041] In this invention, the box 1, box cover, and locking mechanism 4 of the underwater seaweed block collection and transplantation repair device are all made of stainless steel, which helps to improve the corrosion resistance and rust prevention of the overall structure.

[0042] Example 2

[0043] The difference between Example 2 and Example 1 is as follows:

[0044] like Figure 4As shown, the locking mechanism 4 includes two sets of holes on both sides of the housing 1. Each set of holes includes a first hole 21 and a second hole 22. The first hole 21 and the second hole 22 are both strip-shaped. A connecting rod 43 is provided on the end face of the side cover 2. One end of the connecting rod 43 is provided with a vertical part, which is rotatably connected to the end face of the side cover 2. The other end of the connecting rod 43 is provided with a connecting hook 431, which is rotatably connected to the end of the connecting rod 43. The connecting hook 431 is inserted into the first hole 21 or the second hole 22 by rotation.

[0045] When both the side cover 2 and the top cover 3 are closed, the connecting hook 431 is inserted into the first hole 21, and the connecting rod 43 restricts the opening of the side cover 2 and the top cover 3; when the top cover 3 is closed and the side cover 2 is open and overlaps the top cover 3, the connecting hook 431 is inserted into the second hole 22, and the connecting rod 43 restricts the opening of the top cover 3.

[0046] It is important to specify that when the top cover 3 is in the closed state, the hinge axis between the top cover 3 and the housing 1 is the first hinge axis, and the hinge axis between the side cover 2 and the top cover 3 is the second hinge axis; the length of the connecting rod 43 is less than the distance between the first hole 21 and the second hinge axis, and the distance between the first hole 21 and the second hinge axis is less than the distance between the first hole 21 and the first hinge axis. Therefore, when the connecting hook 431 of the connecting rod 43 engages with the first hole 21, it helps to improve the stability of the top cover 3 and the side cover 2, and can reduce the possibility of the top cover 3 or the side cover 2 moving or becoming unstable.

[0047] Example 3

[0048] Based on the description of the overall structure of the underwater seagrass block collection and transplantation restoration device in Examples 1 and 2, the following further describes the method for underwater seagrass block collection and transplantation restoration, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it includes the following steps:

[0049] Step 1: Take the container 1 to the seaweed collection area and use the mud shovel 5 to dig a pit with an area of ​​about 30cm*30cm and a depth of about 15cm in the seaweed growth area. The pit can accommodate the bottom of the container 1. Then, release the locking state of the container lid through the locking mechanism 4, and then open the side cover 2 so that the side cover 2 overlaps the top cover 3. Then, lock the state of the side cover 2 and the top cover 3 through the locking mechanism to open the side opening 11.

[0050] Then, by grasping the handles 13 on both sides, place the box 1 into the pit, and then push the box 1 forward a unit length distance along the side opening 11 to shovel the seaweed and substrate into the box 1 through the side opening 11.

[0051] In this process, the side cover 2 is overlapped on the top cover 3, instead of fully opening both the side cover 2 and the top cover 3. This reduces the contact friction between the side cover 2 and the ground during movement when the box is fully open. Furthermore, the top cover 3 covers the top opening 12 of the box body 1, reducing interference from external water flow when seaweed enters the box body 1. During movement, the water flow inside the box body 1 can be drained and depressurized through the filter screen 14 located away from the side opening 11, further improving the stability of the box body 1 during seaweed harvesting. Next, the locking mechanism is released to lock the side cover 2 in its overlapping state. After the side cover 2 is closed, the locking mechanism 4 is used to further secure the side cover 2 and the top cover 3. Then, the box body 1 is smoothly removed from the water. During the smooth removal of the box body 1, the water at the top of the box body 1 can be drained through the filter screen 14, reducing the overall weight of the box body 1 and facilitating transportation; while the water at the bottom of the box body 1 remains inside, maintaining the seaweed growth environment.

[0052] Furthermore, after the container 1 is smoothly removed from the water, it is placed in a plastic basket containing a small amount of seawater. Then, the plastic basket and the container 1 are transferred together to the seaweed restoration area. The transportation time should be controlled within 2 hours to ensure the freshness of the seaweed seed source.

[0053] Step 2: After transferring the container 1 to the seaweed restoration area, first use a mud pusher to dig a pit with an area of ​​about 30cm*30cm and a depth of about 15cm in the seaweed restoration area. This pit can accommodate the bottom surface of the container 1. Then, release the locking state of the side cover 2 and the top cover 3 through the locking mechanism 4. Next, fully open the side cover 2 and the top cover 3 to open the side opening 11 and the top opening 12. Then, insert the mud pusher 5 into the innermost part of the container 1 through the side opening 11 and the top opening 12 to help push the seaweed block outward. Then, slowly pull the container 1 out of the pit in the direction away from the side opening 11. During the process, use the mud pusher 5 to push the seaweed block into the pit at the same time, ensuring that the seaweed root system of the seaweed block is fully extended. Then, backfill the pit with the bottom material and compact it to make the seaweed root system of the seaweed block in close contact with the bottom material.

[0054] During the repair process in steps one and two above, it is important to note that when the entire structure of tank 1 (referred to as the repair tank) is being taken out of and into the water, it is essential to ensure that tank 1 is stable and not overturned or shaken violently to prevent the substrate on the grass blocks inside from rolling over.

[0055] In summary, the underwater seagrass block collection and transplantation repair device of the present invention is mainly applicable to the collection and transplantation repair of small and medium-sized seagrass blocks distributed underwater. By flipping the side cover 2 and / or the top cover 3, the side opening 11 or the lateral opening and top opening 12 can be opened. When the lateral opening is opened, the seagrass and corresponding substrate in the collection area can be shoveled into the box 1 through the side opening 11. When the side opening 11 and top opening 12 are opened, the mud pusher can be fully extended into the box 1, facilitating the pushing of the seagrass blocks. Simultaneously, the box 1 can be moved relative to the seagrass blocks, thereby improving the efficiency of shoveling out the seagrass blocks. Using the underwater seagrass block collection and transplantation repair device and method of the present invention, it is possible to ensure that the seagrass substrate remains intact during underwater collection and transplantation, and is not dispersed by water currents.

[0056] The embodiments of the present invention are not limited thereto. Based on the above description of the present invention, and using common technical knowledge and conventional means in the field, the present invention can be modified, replaced or combined in various other forms without departing from the basic technical idea of ​​the present invention, and all such modifications, replacements or combinations fall within the scope of protection of the present invention.
