Description

Technical Field

[0001] The present invention relates to the technical field of marine protection, and particularly to an ecological floating raft for marine engineering environmental restoration. Background Art

[0002] Marine engineering refers to new construction, reconstruction, and expansion projects that aim to develop, utilize, protect, and restore marine resources, and whose main project body is located seaward of the coastline. When marine engineering restores and protects marine resources, marine biological remediation technology is used to repair the marine environment. Marine biological remediation technology refers to the comprehensive application of modern biotechnology, using specific organisms to absorb, transform, remove, or degrade environmental pollutants, so that harmful pollutants in the environment are removed through degradation or other means, and biological measures for environmental purification and ecological effect restoration are achieved. During the process of marine engineering environmental restoration, ecological floating rafts are generally used to breed organisms. In the prior art: The patent with the authorization publication number CN 211111299 U discloses an ecological floating raft for marine engineering environmental restoration, including main floating columns. The number of the main floating columns is three. One ends of the three main floating columns are fixedly installed with first connection flanges, and the other ends of the three main floating columns are fixedly connected with second connection flanges. This ecological floating raft for marine engineering environmental restoration, through the cooperation of a garbage collection net, a protective frame, and a collection port, while repairing the environment by breeding organisms, can also collect floating garbage, and thus has a better use effect. However, its biological remediation cages are in a scattered state, resulting in poor stability and inconvenient collection of the bred organisms. Therefore, we propose an ecological floating raft for marine engineering environmental restoration. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an ecological floating raft for marine engineering environmental restoration. The bottom of the ecological floating raft breeding net can move, which is convenient for capturing the internal organisms, and has good structural stability and is easy to use, and can effectively solve the problems in the background art.

[0004] To achieve the above object, the present invention provides the following technical solution: An ecological floating raft for marine engineering environmental restoration, including an upper support frame and a reinforcement unit;

[0005] Upper support frame: Right-angle sliding strips are slidably connected inside the sliding holes at the four corners of its upper surface. The lower surfaces of the right-angle sliding strips are fixedly connected to the upper surface of the lower support frame. A breeding net is provided between the upper support frame and the lower support frame. Floating boxes are provided on the left and right side faces of the upper support frame. A cross floating plate is provided inside the upper support frame;

[0006] Reinforcement unit: Dislocated and arranged on the front and rear side surfaces of the upper support frame. The lower ends of the reinforcement units are all rotatably connected to the lower support frame. The bottom of the floating raft can be lifted upwards, which facilitates the harvesting of the internal cultured organisms. This not only helps the healthy reproduction of the internal organisms, improves the efficiency of environmental restoration, but also helps to increase the economic value generated by environmental restoration, and is convenient to lock and open, ensuring the structural stability and usability.

[0007] Further, the reinforcement unit includes long support rods, short support rods, sliding columns and locking components. The short support rods are respectively rotatably connected to the front and rear side surfaces of the upper support frame through the first rotating shafts in a dislocated manner. The lower ends of the short support rods are respectively rotatably connected to the middle parts of the long support rods through the second rotating shafts. The upper ends of the long support rods are all provided with sliding columns, and the sliding columns are respectively slidably connected to the long sliding grooves adjacent to the front and rear side surfaces of the upper support frame. The lower ends of the long support rods are all rotatably connected to the lower support frame through the third rotating shafts. The locking components are dislocated and arranged on the upper surface of the upper support frame, and the locking components are respectively arranged in cooperation with the vertically corresponding sliding columns, enhancing the structural strength of the floating raft.

[0008] Further, the locking component includes inserting columns, rotating shaft seats and tension springs. The inserting columns are respectively movably inserted into the jacks on the upper surface of the upper support frame, and the lower ends of the inserting columns are respectively arranged in cooperation with the adjacent sliding columns. The upper ends of the inserting columns are provided with rotating shaft seats. The outer surfaces of the inserting columns are all movably sleeved with tension springs. The upper ends of the tension springs are respectively fixedly connected to the lower surfaces of the vertically corresponding rotating shaft seats, and the lower ends of the tension springs are all fixedly connected to the upper surface of the upper support frame, which can automatically lock the sliding columns.

[0009] Further, the locking component also includes L-shaped seats and pull rings. The L-shaped seats are respectively arranged in a dislocated and inverted manner on the upper surface of the upper support frame. The connecting rings at the lower ends of the pull rings are respectively rotatably connected to the outer arc surfaces in the middle of the rotating shaft seats. The L-shaped seats are respectively arranged in cooperation with the adjacent pull rings, which is convenient for positioning the inserting columns.

[0010] Further, a pulling rod is arranged in the middle of the upper surface of the lower support frame, and the upper end of the pulling rod penetrates through the upper surface of the cross-shaped floating board, which is convenient for lifting the lower support frame.

[0011] Further, support strips are arranged at the four corners of the upper surface of the upper support frame, and the upper ends of the support strips are all fixedly connected to the inner side walls of the protective frame. A surrounding net is arranged between the upper support frame and the protective frame to prevent the escape of the organisms raised inside the breeding net.

[0012] Further, fixing rings are arranged at the corners of the vertical surface of the upper support frame, which is convenient for positioning the floating raft.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The ecological floating raft for marine engineering environmental restoration has the following advantages:

[0014] 1. When in use, the upper support frame is put into the sea water. Then, the cross-shaped floating board and the floating box provide buoyancy for the upper support frame, and thus the upper support frame will float on the water surface. Then, the fixing ring is fixed to the seabed by using the anchor rope to prevent the upper support frame from floating away. Then, animals and plants can be cultured inside the culture net to repair the marine environment. When the number of organisms inside the culture net multiplies to a large extent, the lifting device on the external ship is connected to the pulling rod, and then the lifting device is controlled to drive the pulling rod to move upward. Thus, the pulling rod will drive the lower support frame to move upward, and the lower support frame will drive the right-angle sliding strip to slide upward along the sliding hole of the upper support frame. At the same time, the four sides of the culture net will fold, and thus after the bottom of the culture net moves upward, the depth of the culture net will become shallower. Then, the organisms inside can be processed. The bottom of the floating raft can move upward, which is convenient for harvesting the cultured organisms inside. This not only helps the healthy reproduction of the organisms inside, improves the efficiency of environmental restoration, but also helps to increase the economic value generated by environmental restoration.

[0015] 2. The lower support frame will drive the lower end of the long support rod to move upward through the third rotating shaft. Thus, the upper end of the long support rod will drive the sliding column to move along the long sliding groove in a direction away from the center of the upper support frame. While the sliding column slides along the long sliding groove, it will also rotate relative to it. Similarly, relative rotation will occur at the connection between the long support rod and the short support rod, and relative rotation will also occur at the connection between the long support rod, the short support rod and the upper support frame. The locking component locks the sliding column, and thus the long support rod can no longer move. Then, the long support rod and the short support rod will limit the upward movement of the support frame, and thus ensure the stability of the support frame body around the culture net. This can not only provide reinforcement support for the upper support frame and the lower support frame, but also can be folded and contracted, and thus does not affect the upward movement of the lower support frame, and thus ensures the firmness and convenience of the use of the floating raft.

[0016] 3. The pull ring can be pulled upward. The pull ring drives the plug post to move upward through the rotating shaft seat, and stretches the tension spring. Then, the lower end of the plug post is separated from the sliding post, and the plug post will no longer restrict the movement of the sliding post. Then, the pull ring is rotated 90 degrees around the axis of the rotating shaft seat. Then, the protrusion at the edge of the pull ring will move above the L-shaped seat. Then, the L-shaped seat will prevent the pull ring from moving downward. After the pull rings on both sides are all pulled up and positioned, after the processing is completed, the pull ring is rotated back to the initial angle. Then, the tension spring in the stretched state will drive the plug post to reset through the rotating shaft seat. Then, the pull rod is released. Then, the lower support frame moves downward under the action of gravity. Then, the support frame will drive the long support rod and the short support rod to reset. The sliding post will move towards the direction close to the center of the upper support frame. And during the sliding process, the plug post will be bumped up. The side of the lower end of the plug post far from the center of the upper support frame is an inclined surface. Then, after the sliding post passes over the plug post, the tension spring drives the plug post to reset, thereby realizing the locking of the sliding post. When locking is required, it can be automatically locked after moving into place. Then, it can be positioned after being opened and can remain in the opened state for a long time. Then, the locking components can be opened alternately, ensuring the convenience during use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 3 , the present invention provides the following technical solutions:

[0023] Embodiment 1: An ecological floating raft for marine engineering environmental restoration, comprising an upper support frame 1 and a reinforcement unit 7;

[0024] Upper support frame 1: Right-angle sliding bars 2 are slidably connected inside the sliding holes at the four corners of its upper surface. The lower surfaces of the right-angle sliding bars 2 are fixedly connected to the upper surface of the lower support frame 3. A breeding net 4 is provided between the upper support frame 1 and the lower support frame 3. Float boxes 5 are provided on the left and right side faces of the upper support frame 1. A cross-shaped floating plate 6 is provided inside the upper support frame 1. A pulling rod 8 is provided in the middle of the upper surface of the lower support frame 3. The upper end of the pulling rod 8 penetrates through the upper surface of the cross-shaped floating plate 6. Support bars 9 are provided at the four corners of the upper surface of the upper support frame 1. The upper ends of the support bars 9 are fixedly connected to the inner side walls of the protection frame 10. A surrounding net 11 is provided between the upper support frame 1 and the protection frame 10. The support bars 9 and the protection frame 10 provide support for the surrounding net 11. The surrounding net 11 is higher than the sea surface to prevent the escape of internal animals. Fixed rings 12 are provided at the corners of the vertical surface of the upper support frame 1;

[0025] Reinforcement unit 7: Disposed at the front and rear side faces of the upper support frame 1 in a staggered manner. The lower ends of the reinforcement units 7 are rotatably connected to the lower support frame 3;

[0026] Specifically, with such a setting, when in use, the upper support frame 1 is put into the sea water. Then, the cross-shaped floating plate 6 and the float boxes 5 provide buoyancy for the upper support frame 1. Thus, the upper support frame 1 will float on the water surface. Then, the fixed rings 12 are fixed to the seabed by using anchor ropes to prevent the upper support frame 1 from floating away. Then, animals and plants can be bred inside the breeding net 4 to repair the marine environment. When the number of organisms inside the breeding net 4 multiplies to a large extent, the lifting equipment on the external ship is connected to the pulling rod 8. Then, the lifting equipment is controlled to drive the pulling rod 8 to move upward. Thus, the pulling rod 8 will drive the lower support frame 3 to move upward. The lower support frame 3 drives the right-angle sliding bars 2 to slide upward along the sliding holes of the upper support frame 1. At the same time, the four sides of the breeding net 4 will fold. Thus, after the bottom of the breeding net 4 moves upward, the depth of the breeding net 4 will become shallower. Then, the organisms inside can be processed;

[0027] Embodiment 2:

[0028] The difference between this embodiment and Embodiment 1 is that:

[0029] In this embodiment, the reinforcement unit 7 includes long support rods 71, short support rods 72, sliding columns 73 and locking components 74. The short support rods 72 are respectively rotatably connected to the front and rear side surfaces of the upper support frame 1 in a staggered manner through the first rotating shafts. The lower ends of the short support rods 72 are respectively rotatably connected to the middle parts of the long support rods 71 through the second rotating shafts. The upper ends of the long support rods 71 are all provided with sliding columns 73. The sliding columns 73 are respectively slidably connected to the long sliding grooves adjacent to the front and rear side surfaces of the upper support frame 1. The lower ends of the long support rods 71 are respectively rotatably connected to the lower support frame 3 through the third rotating shafts. The locking components 74 are arranged on the upper surface of the upper support frame 1 in a staggered manner. The locking components 74 are respectively arranged in cooperation with the vertically corresponding sliding columns 73.

[0030] Specifically, with such a setting, the lower support frame 3 will drive the lower ends of the long support rods 71 to move upward through the third rotating shafts. Furthermore, the upper ends of the long support rods 71 will drive the sliding columns 73 to move along the long sliding grooves in a direction away from the center of the upper support frame 1. While the sliding columns 73 slide along the long sliding grooves, they will also rotate relative to the long sliding grooves. Similarly, the joints between the long support rods 71 and the short support rods 72 will rotate relatively, and the joints between the long support rods 71 and the short support rods 72 and the upper support frame 1 will also rotate relatively. The locking components 74 lock the sliding columns 73. Furthermore, the long support rods 71 will no longer be able to move. Then, the long support rods 71 and the short support rods 72 will limit the upward movement of the support frame 3, thereby ensuring the stability of the support body around the breeding net 4.

[0031] Embodiment Three:

[0032] The difference between this embodiment and Embodiment Two lies in:

[0033] In this embodiment, the locking components 74 include plug posts 741, rotating shaft seats 742 and tension springs 743. The plug posts 741 are respectively movably inserted into the jacks on the upper surface of the upper support frame 1. The lower ends of the plug posts 741 are respectively arranged in cooperation with the adjacent sliding columns 73. The upper ends of the plug posts 741 are provided with rotating shaft seats 742. The outer surfaces of the plug posts 741 are all movably sleeved with tension springs 743. The upper ends of the tension springs 743 are respectively fixedly connected to the lower surfaces of the vertically corresponding rotating shaft seats 742. The lower ends of the tension springs 743 are all fixedly connected to the upper surface of the upper support frame 1. The locking components 74 also include L-shaped seats 744 and pull rings 745. The L-shaped seats 744 are respectively arranged on the upper surface of the upper support frame 1 in a staggered and inverted manner. The connecting rings at the lower ends of the pull rings 745 are respectively rotatably connected to the outer arc surfaces in the middle of the rotating shaft seats 742. The L-shaped seats 744 are respectively arranged in cooperation with the adjacent pull rings 745.

[0034] Specifically, with such a setting, the pull ring 745 can be pulled upward. The pull ring 745 drives the insertion post 741 to move upward through the rotating shaft seat 742, and stretches the tension spring 743. Then, the lower end of the insertion post 741 is separated from the sliding post 73, and the insertion post 741 will no longer restrict the movement of the sliding post 73. Then, the pull ring 745 is rotated 90 degrees around the axis of the rotating shaft seat 742. Then, the protrusion at the edge of the pull ring 745 will move above the L-shaped seat 744. Then, the L-shaped seat 744 will prevent the pull ring 745 from moving downward. After the pull rings 745 on both sides are all pulled up and positioned, after the processing is completed, the pull ring 745 is rotated back to the initial angle. Then, the tension spring 743 in the stretched state will drive the insertion post 741 to reset through the rotating shaft seat 742. Then, the pull rod 8 is released. Then, the lower support frame 3 moves downward under gravity. Then, the support frame 3 will drive the long support rod 71 and the short support rod 72 to reset. The sliding post 73 will move in the direction close to the center of the upper support frame 1, and the insertion post 741 will be knocked up during the sliding process. The side of the lower end of the insertion post 741 away from the center of the upper support frame 1 is an inclined surface. Then, after the sliding post 73 passes over the insertion post 741, the tension spring 743 drives the insertion post 741 to reset, thereby realizing the locking of the sliding post 73.

[0035] The working principle of an ecological floating raft for marine engineering environmental restoration provided by the present invention is as follows: When in use, the upper support frame 1 is put into seawater, and then the cross floating plates 6 and floating boxes 5 provide buoyancy for the upper support frame 1, so that the upper support frame 1 will float on the water surface. Then, the fixed ring 12 is fixed to the seabed by using an anchor rope to prevent the upper support frame 1 from drifting away. Then, animals and plants can be cultured inside the culture net 4 to repair the marine environment. When the number of organisms inside the culture net 4 multiplies and needs to be captured, the pull ring 745 can be pulled upward. The pull ring 745 drives the plug post 741 to move upward through the rotating shaft seat 742 and stretches the tension spring 743. Then, the lower end of the plug post 741 is separated from the sliding post 73, and the plug post 741 no longer restricts the movement of the sliding post 73. Then, the pull ring 745 is rotated 90 degrees around the axis of the rotating shaft seat 742. Then, the protrusion at the edge of the pull ring 745 will move above the L-shaped seat 744, and the L-shaped seat 744 will prevent the pull ring 745 from moving downward. After the pull rings 745 on both sides are pulled up and positioned, the lifting equipment on the external ship is connected to the pull rod 8, and then the lifting equipment is controlled to drive the pull rod 8 to move upward. Then, the pull rod 8 will drive the lower support frame 3 to move upward. The lower support frame 3 drives the right-angled sliding strip 2 to slide upward along the sliding hole of the upper support frame 1. At the same time, the four sides of the culture net 4 will fold. At the same time, the lower support frame 3 will drive the lower end of the long support rod 71 to move upward through the third rotating shaft. Then, the upper end of the long support rod 71 will drive the sliding post 73 to move along the long sliding groove in a direction away from the center of the upper support frame 1. When the sliding post 73 slides along the long sliding groove, it will also rotate relative to it. Similarly, the connection between the long support rod 71 and the short support rod 72 will rotate relatively, and the connection between the long support rod 71 and the short support rod 72 and the upper support frame 1 will also rotate relatively. Then, after the bottom of the culture net 4 moves upward, the depth of the culture net 4 will become shallower, and then the organisms inside can be processed. After the processing is completed, the pull ring 745 is rotated back to the initial angle. Then, the tension spring 743 in the stretched state will drive the plug post 741 to reset through the rotating shaft seat 742. Then, the pull rod 8 is released, and then the lower support frame 3 moves downward under gravity. Then, the support frame 3 will drive the long support rod 71 and the short support rod 72 to reset. The sliding post 73 will move in a direction close to the center of the upper support frame 1, and the plug post 741 will be knocked up during the sliding process. The lower end of the plug post 741 on the side away from the center of the upper support frame 1 is a slope. Then, after the sliding post 73 passes over the plug post 741, the tension spring 743 drives the plug post 741 to reset, thereby realizing the locking of the sliding post 73. Then, the long support rod 71 can no longer move, and then the long support rod 71 and the short support rod 72 will limit the upward movement of the support frame 3, thereby ensuring the stability of the support structure around the culture net 4.

[0036] The above are only embodiments of the present invention, and do not thus limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present invention.
