Description

Technical Field

[0001] This utility model relates to the field of marine navigation mark technology, and more specifically, to a marine navigation mark that prevents biofouling. Background Technology

[0002] As an important navigational aid to ensure the safety of ship navigation, marine buoys are exposed to the marine environment for a long time. Their surfaces are easily attached by marine organisms such as barnacles, shellfish, and algae. Most existing buoys are made of metal, plastic, or composite materials. When these materials are soaked in seawater, they form an interface suitable for microbial colonization. Over time, the biofilm layer gradually thickens and eventually develops into a dense biofouling layer.

[0003] Currently, the conventional method for dealing with biofouling on navigation aids mainly relies on manual cleaning. Maintenance personnel need to regularly climb onto the surface of the aid and use tools such as scrapers and shovels to physically remove the attached organisms. However, the high frequency of manual removal operations significantly increases the operation and maintenance costs, especially in remote sea areas or in harsh sea conditions, where personnel deployment poses safety hazards. Secondly, manual cleaning is difficult to completely remove the biofouling, and residual biological secretions can accelerate the subsequent fouling process, causing changes in the buoyancy characteristics of the aid and thus affecting its usability. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a marine navigation mark that prevents biofouling, so as to solve the problem that in the prior art, maintenance personnel need to clean it manually, which not only increases their workload but also has poor cleaning effect, thus affecting the use of the navigation mark.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a marine navigation mark that prevents biofouling, comprising a navigation mark body, an outer ring sleeved on the outer side of the middle part of the navigation mark body, connecting blocks inserted into both the front and rear sides of the outer ring, a support plate installed at the bottom of the connecting block, and scrapers installed on the adjacent side of the support plate on both the front and rear sides.

[0006] The navigation mark body has a drive motor installed on the left side of the middle part, a gear installed at the output end of the drive motor, a rotating groove opened on the left side of the interior of the navigation mark body, an annular groove opened in the middle part of the navigation mark body, and a toothed ring rotatably connected to the inner wall of the annular groove.

[0007] The gear is rotatably connected to the inner wall of the rotating groove and meshes with the gear ring. The rotating groove communicates with the ring groove, and the gear ring is fixedly connected to the inner ring wall of the outer ring.

[0008] The outer ring has slots on both the front and rear sides, and the inner walls of the slots have limiting grooves on both the left and right sides. The connecting block has sliding grooves on both the left and right sides inside, and a sliding plate is slidably connected to the inner wall of the sliding groove. A post is installed on one side of the sliding plate and a spring is installed on the other side. A rotating rod is inserted into the middle of the connecting block, and pull ropes are installed on both the left and right sides of the lower part of the rotating rod.

[0009] The pull ropes on both sides have their opposite ends passing through the slide groove and are installed between them and the slide plate. The springs on both sides have their adjacent ends installed on the inner wall of the slide groove. The rotating rod passes through the top of the connecting block.

[0010] The connecting block is inserted through one end of each of the left and right side posts and is inserted into the inner wall of the limiting groove. The connecting block is inserted into the inner wall of the slot.

[0011] Among them, the adjacent sides of the scrapers on the front and rear sides are in contact with the outer side of the navigation mark body, and the top of the support plate is in contact with the bottom of the outer ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the above scheme, the outer ring is driven to rotate around the outside of the buoy, and the support plate moves synchronously. The support plate then drives the scraper to scrape along the surface of the buoy, thus achieving automatic removal of biofouling on the buoy. This eliminates the need for maintenance personnel to manually clean it with tools, thereby reducing labor intensity, inhibiting biofilm formation, and improving the long-term operational efficiency of the maritime buoy.

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1: Please refer to Figures 1 to 9 This utility model provides a technical solution: a marine navigation mark that prevents biofouling, comprising a navigation mark body 1, an outer ring 2 fitted on the outer side of the middle part of the navigation mark body 1, connecting blocks 8 inserted on both the front and rear sides of the outer ring 2, a support plate 3 installed at the bottom of the connecting blocks 8, and scrapers 7 installed on the adjacent sides of the support plates 3 on both the front and rear sides. The adjacent sides of the scrapers 7 are in contact with the outer side of the navigation mark body 1, thereby scraping the outer side of the navigation mark body 1 with the scrapers 7 to reduce biofouling and improve the use effect of the navigation mark body 1. The top of the support plate 3 is in contact with the bottom of the outer ring 2, so that the scrapers 7 can be removed for maintenance or replacement.

[0027] First, the outer ring 2 is driven to rotate on the outside of the buoy body 1, which in turn drives the front and rear support plates 3 to rotate synchronously on the outside of the buoy body 1. The scraper 7 is used to scrape the outside of the buoy body 1, and maintenance personnel do not need to manually remove it with tools, thereby reducing their workload and reducing the attachment of organisms.

[0028] Example 2: Based on Example 1, in order to drive the front and rear support plates 3 to rotate on the outside of the buoy body 1, a drive motor 4 is installed on the left side of the middle part of the buoy body 1. A gear 5 is installed at the output end of the drive motor 4. A rotating groove 17 is opened on the left side of the interior of the buoy body 1. An annular groove 16 is opened in the middle of the buoy body 1. A toothed ring 6 is rotatably connected to the inner wall of the annular groove 16. The gear 5 is rotatably connected to the inner wall of the rotating groove 17 and meshes with the toothed ring 6. Thus, by rotating the gear 5, the toothed ring 6 is driven to rotate synchronously. The rotating groove 17 and the annular groove 16 are connected. The toothed ring 6 is fixedly connected to the inner wall of the outer ring 2. Thus, when the toothed ring 6 rotates along the inner wall of the annular groove 16, it synchronously drives the outer ring 2 to rotate, thereby driving the front and rear scrapers 7 to scrape the outside of the buoy body 1, thereby reducing the attachment of organisms.

[0029] First, start the drive motor 4, which drives the gear 5 to rotate on the inner wall of the rotating groove 17, and drives the meshing gear ring 6 to rotate on the inner wall of the ring groove 16. This synchronously drives the outer ring 2 to rotate on the outer side of the buoy body 1, and then drives the front and rear support plates 3 to rotate synchronously on the outer side of the buoy body 1. The scraper 7 is used to scrape the outer side of the buoy body 1, thereby reducing the workload of maintenance personnel, reducing the attachment of organisms, and further increasing the effectiveness of the buoy body 1. After cleaning, turn off the drive motor 4 to stop the scraping operation on the outer side of the buoy body 1.

[0030] Example 3: Based on Example 2, to facilitate subsequent maintenance or replacement of the scraper 7, slots 15 are provided on both the front and rear sides of the outer ring 2. Restriction grooves 14 are provided on both the left and right sides of the inner wall of the slots 15. Sliding grooves 12 are provided on both the left and right sides of the inner wall of the connecting block 8. A sliding plate 10 is slidably connected to the inner wall of the sliding groove 12. A post 9 is installed on one side of the sliding plate 10, and a spring 11 is installed on the other side. A rotating rod 18 is inserted into the middle of the connecting block 8. Pull ropes 13 are installed on both the left and right sides of the lower part of the rotating rod 18. The opposite ends of the pull ropes 13 pass through the sliding grooves 12 and are installed between them and the sliding plate 10. Thus, by rotating the rotating rod 18, the scraper 7 can be moved using… Pull ropes 13 on both sides drive the left and right side plugs 9 to disengage from the limiting grooves 14, thereby releasing the restriction between the connecting block 8 and the outer ring 2. The near ends of the left and right side springs 11 are installed on the inner wall of the slide groove 12, so that the elastic force of the springs 11 pushes the plugs 9 to always be inserted into the limiting grooves 14 for subsequent disassembly and use. The rotating rod 18 passes through the top of the connecting block 8, and the far ends of the left and right side plugs 9 pass through the connecting block 8 and are inserted into the inner wall of the limiting groove 14. The connecting block 8 is inserted into the inner wall of the slot 15, so that the connecting block 8 can be pulled down to disengage from the slot 15, thereby removing the entire support plate 3 and facilitating the maintenance or replacement of the scraper 7.

[0031] After prolonged use, the scraper 7 may become ineffective. In this case, rotate the lever 18 to wind the pull ropes 13 on both sides around its outer side, while simultaneously pulling the left and right slide plates 10 to move towards each other along the inner wall of the groove 12, compressing the spring 11 and placing it in a compressed state within the groove 12. At this time, the insert 9 retracts to the inner wall of the groove 12 and disengages from the limiting groove 14. Then, pull down the support plate 3 to disengage the connecting block 8 from the slot 15. The scraper 7 can then be maintained or replaced. After maintenance, insert the connecting block 8 into the inner wall of the slot 15 and release the lever 18. This utilizes the spring force of the spring 11 to push the slide plates 10 back to their original positions and move the insert 9 back into the inner wall of the limiting groove 14, thus securing the connecting block 8 to the outer ring 2 for future replacement.

[0032] The working process of this utility model is as follows:

[0033] When in use, first start the drive motor 4, which drives the gear 5 to rotate on the inner wall of the rotating groove 17, and drives the meshing gear ring 6 to rotate on the inner wall of the ring groove 16, thereby synchronously driving the outer ring 2 to rotate on the outer side of the buoy body 1, and then driving the front and rear support plates 3 to rotate synchronously on the outer side of the buoy body 1. The scraper 7 is used to scrape the outer side of the buoy body 1, and maintenance personnel do not need to manually remove it with tools, thereby reducing their workload and reducing the attachment of organisms, further increasing the effectiveness of the buoy body 1. After cleaning, turn off the drive motor 4 to stop the scraping operation on the outer side of the buoy body 1.

[0034] After prolonged use, the scraper 7 may become ineffective. In this case, rotate the lever 18 to wind the pull ropes 13 on both sides around its outer side, while simultaneously pulling the left and right slide plates 10 to move towards each other along the inner wall of the groove 12, compressing the spring 11 and placing it in a compressed state within the groove 12. At this time, the insert 9 retracts to the inner wall of the groove 12 and disengages from the limiting groove 14. Then, pull down the support plate 3 to disengage the connecting block 8 from the slot 15. The scraper 7 can then be maintained or replaced. After maintenance, insert the connecting block 8 into the inner wall of the slot 15 and release the lever 18. This utilizes the spring force of the spring 11 to push the slide plates 10 back to their original positions and move the insert 9 back into the inner wall of the limiting groove 14, thus securing the connecting block 8 to the outer ring 2 for future replacement.
