Technical Field

[0001] The invention relates to a device for intercepting floating marine organisms, belonging to the technical field of marine engineering. Background Art

[0002] The plankton interception device plays a key role in the operation of marine-related facilities and ecological protection. It can prevent excessive accumulation of plankton and damage to the marine ecosystem through physical interception, acoustic repulsion, optical repulsion and other means, maintain ecological balance, and at the same time, prevent plankton from clogging the water intakes, pipelines and filtration equipment of coastal industrial facilities, ensure the normal operation of power plants, chemical plants, etc., reduce production risks and maintenance costs caused by equipment failure, and ensure the smooth development of marine resources and industrial production.

[0003] At present, in the process of intercepting plankton by physical shielding, the aperture of the intercepting net is fixed, which is not only easy to be blocked, but also has low interception efficiency. In addition, during the installation of the intercepting net, the position is fixed, and the shape of the intercepting net cannot be adjusted according to the impact force of seawater, which affects the installation stability of the device. In addition, the floating objects intercepted by the intercepting net on the sponge cannot be pushed, which is not convenient for collection and processing.

[0004] For this reason, a device for intercepting floating marine organisms is designed to optimize the above-mentioned problem. Summary of the invention

In addition, the grooming strip plates uniformly arranged at the bottom of the U-shaped plates and the fine bristles in contact with each other between the sides of the grooming strip plates form a gradient pore structure during the interception process, realizing step-by-step filtration and improving the interception effect during use. By providing a through port and a push block at the bottom of the U-shaped plate, and using the pushing mechanism composed of a limiting ring, a movable floating plate, and a second pull rope, during the use of the device, the wind and waves can control the up-and-down swing of the movable floating plate, and during the up-and-down swing of the floating plate, the second pull rope controls the up-and-down swing of the push block inside the through port, which can realize the lateral push of the water flow inside the U-shaped plate, so that the floating objects inside the U-shaped plate flow towards the end, facilitating the collection of sundries and having higher practicability. By providing a V-shaped scraper, a vertical rod, a cross bar, and a sliding rod at the front end of the comb-shaped strip plate, and using the first pull rope under the movable floating plate, during the process of the waves controlling the拨动 of the movable floating plate, the V-shaped scraper can be controlled to slide along the front end of the comb-shaped strip plate to clean the comb-shaped strip plate, improving the service life and use effect of the device.

[0039] To make the technical solutions of the present invention clearer and more definite for those skilled in the art, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the implementation manners of the present invention are not limited thereto.

[0040] As Figure 1-Figure 8As shown in the figure, this embodiment provides a device for intercepting planktonic marine organisms, including a cable 1. Fixed rings 2 are evenly fixed on the cable 1 along the length direction. A positioning floating plate 3 is horizontally fixed on one side of the cable 1 on the fixed ring 2. C-shaped plates 4 are fixed at the bottoms of the fixed rings 2. The width of the top end of the C-shaped plate 4 is smaller than that of the bottom end. A connecting mechanism 5 is provided between adjacent C-shaped plates 4. Comb-shaped strip plates 6 are evenly and vertically installed at the bottoms of the C-shaped plates 4 along the length direction. One end of adjacent comb-shaped strip plates 6 located at the bottom of the positioning floating plate 3 is a narrow opening, and fine bristles 8 are provided on the side edges at the narrow openings of adjacent comb-shaped strip plates 6. The fine bristles 8 on the comb-shaped strip plates 6 are staggered with each other. A cleaning mechanism 7 is provided at one end of the comb-shaped strip plate 6 away from the fine bristles 8. Pushing mechanisms 9 are provided inside the C-shaped plates 4. Positioning mechanisms 10 are provided at both ends of the cable 1. Leakage prevention mechanisms 11 are provided between the comb-shaped strip plates 6 at the ends of the cable 1 and the positioning mechanisms 10.

[0041] General working principle: When in use, the cable 1 is placed on the sea surface, and the cable 1 is floated by the positioning floating plate 3. The top of the C-shaped plate 4 is flush with the sea surface, and the open direction of the C-shaped plate 4 is aligned with the direction of interception. After adjusting the enclosed area of the cable 1, the end of the cable 1 is positioned by the positioning mechanism 10. During the use process, planktonic organisms are blocked by the evenly arranged comb-shaped strip plates 6. The distance between one end of adjacent comb-shaped strip plates 6 close to the planktonic organisms is the largest, and then gradually decreases along the width direction of the comb-shaped strip plate 6, presenting a gradient gap structure, which can perform step-by-step filtration and effectively prevent blockage. In addition, the fine bristles 8 at the narrow end of the comb-shaped strip plate 6 form the minimum passing aperture of the interception device, ensuring the interception effect on planktonic organisms. During the interception process, some floating objects will be intercepted by the cable 1 on the top of the C-shaped plate 4. At this time, the waves in the sea will control the operation of the pushing mechanism 9 to convey the floating objects towards one end of the cable 1 for collection and treatment. In addition, when in use, due to the different magnitudes of water flow impact, when the impact force is large, the cable 1 will pull the positioning mechanism 10 and release a certain amount of the cable 1 to reduce the impact force borne by the cable 1 and ensure the stable use of the device. When the cable 1 is stretched, the leakage prevention mechanism 11 forms a protection at the end of the device to prevent the passage of floating objects or planktonic organisms.

[0042] In this embodiment, the connecting mechanism 5 includes a hinge 501 and a first rubber corrugated plate 502. The hinge 501 is installed between the ends of two groups of C-shaped plates 4. A first rubber corrugated plate 502 is provided between the bottoms of adjacent C-shaped plates 4. A second rubber corrugated plate 503 is provided between the tops of adjacent C-shaped plates 4.

[0043] Local working principle: The U-shaped plates 4 are connected by hinges 501, ensuring that the U-shaped plates 4 can swing relative to each other for adjustment, facilitating the device to be enclosed in different shapes. Additionally, during the process of adjusting the position of the U-shaped plates 4, the use of the first rubber corrugated plate 502 and the first rubber corrugated plate 502 can form an uninterrupted connection between the U-shaped plates 4, enabling floating objects to be transported along the U-shaped plates 4.

[0044] In this embodiment, the pushing mechanism 9 includes a through port 901, a pushing block 902, and a reciprocating lifting component. The through port 901 is opened at the bottom end of the U-shaped plate 4. The pushing blocks 902 are hingedly installed inside the through port 901, and the pushing blocks 902 are hingedly installed on the same side of the U-shaped plate 4. The shape of the pushing block 902 is a fan-shaped cylinder. A reciprocating lifting component for controlling the up-and-down swing of the pushing block 902 is provided at the top of the U-shaped plate 4.

[0045] Local working principle: When impacted by ocean waves, the operation of the reciprocating lifting component will be controlled to lift the pushing block 902 reciprocally. When the pushing block 902 swings, a thrust along the length direction of the U-shaped plate 4 will be exerted on the seawater inside the U-shaped plate 4. Consequently, the floating objects will move along with the movement of the seawater, and the floating objects will be pushed in one direction.

[0046] In this embodiment, the reciprocating lifting component includes a limiting ring 903, a movable floating plate 904, and a second pulling rope 905. The limiting ring 903 is sleeved on the cable 1. The limiting rings 903 are located on both sides of the fixed ring 2 respectively. The movable floating plate 904 is fixed on the limiting ring 903. The movable floating plate 904 is located on the symmetric side of the positioning floating plate 3. A second pulling rope 905 is provided between the bottom end of the movable floating plate 904 and the top of the pushing block 902.

[0047] Local working principle: Under the fluctuation of ocean waves, the movable floating plate 904 will swing up and down with the cable 1 as the axis. The swing of the movable floating plate 904 can exert a pulling force on the pushing block 902 through the second pulling rope 905, thereby controlling the pushing block 902 to swing synchronously with the movable floating plate 904.

[0048] In this embodiment, the cleaning mechanism 7 includes a V-shaped scraping plate 701 and a sliding component. The V-shaped scraping plates 701 are uniformly arranged along the vertical direction of the comb-shaped strip plate 6, and the inner side of the V-shaped scraping plate 701 is attached to the outer side of the comb-shaped strip plate 6. A sliding component for controlling the up-and-down sliding of the V-shaped scraping plate 701 is provided on the U-shaped plate 4.

[0049] Local working principle: During the use of the device, to prevent organisms from parasitizing on the comb-shaped strip plate 6, the sliding component can be used to control the V-shaped scraping plate 701 to slide vertically along the length direction of the comb-shaped strip plate 6, continuously cleaning the surface of the comb-shaped strip plate 6.

[0050] In this embodiment, the sliding assembly includes a vertical rod 702, a horizontal rod 703, a sliding rod 704, and a first pulling rope 705. The vertical rod 702 is vertically arranged at the front end of the comb-shaped strip plate 6, and the V-shaped scraping plate 701 is fixed on the vertical rod 702. A horizontal rod 703 is fixed between the tops of the vertical rods 702. A sliding rod 704 is vertically fixed on the top of the horizontal rod 703. The sliding rod 704 is vertically slidably connected to the C-shaped plate 4. The bottom of the movable floating plate 904 is provided with a first pulling rope 705. The bottom end of the first pulling rope 705 extends below the C-shaped plate 4 and is fixedly connected to the horizontal rod 703.

[0051] Local working principle: During the swinging process of the movable floating plate 904, the horizontal rod 703 can be pulled through the use of the first pulling rope 705, and after losing the pulling force, the horizontal rod 703 resets under the action of gravity. The horizontal rod 703 drives the vertical rod 702 to move simultaneously, and then drives multiple groups of V-shaped scraping plates 701 to slide and clean.

[0052] In this embodiment, a sliding hole is arranged along the length direction at the bottom of the C-shaped plate 4. Both the sliding rod 704 and the first pulling rope 705 pass through the inside of the sliding hole.

[0053] Local working principle: During the process of controlling the movement of the horizontal rod 703, the sliding rod 704 vertically slides inside the sliding hole, and the first pulling rope 705 also passes through other sliding holes for limiting, ensuring the stable movement of the horizontal rod 703.

[0054] In this embodiment, the positioning mechanism 10 includes a conical plug rod 1001 and an elastic tensioning mechanism 1002. The conical plug rod 1001 is vertically fixed at the seabed. An elastic tensioning mechanism 1002 is installed at the top of the conical plug rod 1001. The end of the cable 1 is connected to the elastic tensioning mechanism 1002.

[0055] Local working principle: When fixing the cable 1, the conical plug rod 1001 is inserted into the seabed, the elastic tensioning mechanism 1002 is located on the sea surface, the end of the cable 1 is connected to the elastic tensioning mechanism 1002, and the elastic tensioning mechanism 1002 elastically tightens the cable 1.

[0056] In this embodiment, the elastic tensioning mechanism 1002 includes a box body 10021, a reel 10022, a fixing rod 10023, a clockwork spring 10024, and a wire hole 10025. The box body 10021 is fixed at the top end of the conical plug rod 1001. A reel 10022 is rotatably installed at the inner bottom of the box body 10021. The end of the cable 1 is fixed on the reel 10022. A wire hole 10025 for the cable 1 to pass through is formed on the box body 10021. A fixing rod 10023 is fixed at the top end of the reel 10022. A clockwork spring 10024 is installed on the outer side of the fixing rod 10023. The outer end of the clockwork spring 10024 is fixedly connected to the inner wall of the box body 10021.

[0057] Partial working principle: When the cable 1 is subjected to a large water flow impact force, the rotation of the reel 10022 will be controlled to release the cable 1, and during the rotation of the reel 10022, the clockwork spring 10024 will be compressed to ensure that the cable 1 can automatically reset when the water flow impact force decreases.

[0058] In this embodiment, the leakage prevention mechanism 11 includes an anti-leakage net 1101 and a ring 1102. The ring 1102 is evenly arranged on the end of the cable 1. The anti-leakage net 1101 is installed between the bottom ends of the ring 1102. The anti-leakage net 1101 hangs down loosely. One end of the anti-leakage net 1101 is fixedly connected to the conical plug rod 1001, and the other end of the anti-leakage net 1101 is fixedly connected to the comb-shaped strip 6.

[0059] Partial working principle: when the cable 1 is stretched, the anti-leakage net 1101 in a loose state will be gradually straightened, increasing the interception area, effectively preventing the passage of floating objects and plankton, and ensuring the interception effect.

[0060] The above description is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which belong to the protection scope of the present invention.
