Description

Technical Field

[0001] This invention relates to the field of artificial reef technology, specifically to ecological artificial reefs used for the ecological restoration of benthic animals. Background Technology

[0002] Benthic animals are aquatic animal groups that spend all or most of their life cycle at the bottom of water bodies. They are an important component of aquatic ecosystems and play a vital role in them. However, under the multiple pressures of human activities and global climate change, as well as the risk of predation by other underwater predators, the survival of freshwater benthic animals is seriously threatened.

[0003] Current methods for restoring the ecological environment of benthic animals typically involve placing artificial reefs in specific waters. Benthic animals then enter the reefs to live, and the reefs provide a relatively safe habitat for them. To prevent larger predators from catching the benthic animals, the entrances and exits on the surface of the reefs are usually quite small. However, with long-term use, some shellfish and other organisms from the bottom of the water attach themselves to the entrances and exits of the reefs. Even after the shellfish die, they remain attached to these locations. When these organisms accumulate, they can block the entrances and exits, thus affecting the access of other benthic animals to and from the reefs. Summary of the Invention

[0032] Please see Figures 1-10 The present invention provides a technical solution: an ecological fish reef for the ecological restoration of benthic animals, including a reef body 1, the reef body 1 having three inner cavities and multiple inlets and outlets 2 fixedly connected to the inner cavities on the reef body 1, the multiple inlets and outlets 2 being distributed in a circumferential array on the reef body 1 and each inlet and outlet 2 being connected to an inner cavity.

[0033] The inlet / outlet 2 is equipped with a cleaning mechanism, which is used to remove shellfish that are attached to the inner wall of the inlet / outlet 2 and cause blockage to the inlet / outlet 2.

[0034] The reef 1 is equipped with a drive mechanism, which is used to drive the cleaning mechanisms on all the inlets and outlets 2;

[0035] The reef 1 is equipped with a discharge mechanism, which is used to discharge the blockages left in the inlet and outlet 2 by the cleaning mechanism when the drive mechanism is running.

[0036] During operation, after the reef 1 is placed in the target water area, the benthic animals in that area will enter the inner cavity of the reef 1 through multiple inlets and outlets 2, thus providing a safe living environment for the benthic animals. However, some shellfish will attach to the inner wall of the inlets and outlets 2 and remain attached even after the shellfish die. When these animals accumulate in large quantities, they will cause blockage of the inlets and outlets 2. At this time, the drive mechanism is activated, which drives the cleaning mechanism and the discharge mechanism. The cleaning mechanism removes the shellfish and other blockages attached to the inner wall of the inlets and outlets 2 from the inner wall of the inlets and outlets 2. Then, the discharge mechanism discharges these removed items out of the inlets and outlets 2, thereby achieving the effect of automatically clearing the blockages in the inlets and outlets 2 of the reef 1. This effectively ensures that the benthic animals can enter and exit the reef 1 relatively smoothly, improving the effect of benthic animal ecological restoration.

[0037] like Figure 1-2 As shown, as a further embodiment of the present invention, the cleaning mechanism includes a rotating ring 3, which is sleeved on the inlet / outlet 2 and rotatably connected to the inlet / outlet 2; four scrapers 4 are provided inside the inlet / outlet 2, which are arranged in a circumferential array inside the inlet / outlet 2 and all four scrapers 4 are in contact with the inner wall of the inlet / outlet 2; all four scrapers 4 are fixedly connected to the rotating ring 3.

[0038] During operation, when the rotating ring 3 is driven to rotate 90 degrees, the rotating ring 3 can drive the four scrapers 4 connected to it to move to the position of the next scraper 4 respectively. The four scrapers 4 can then completely scrape the inner wall of the inlet and outlet 2. Under the action of the four scrapers 4, the shellfish and other blockages attached to the inner wall of the inlet and outlet 2 can be scraped off.

[0039] like Figure 1-3 As shown, as a further embodiment of the present invention, the driving mechanism includes a first sliding frame 5, which is located above the reef 1 and is slidably connected to the reef 1; a plurality of connecting frames 6 are fixedly connected to the first sliding frame 5, the number of connecting frames 6 being the same as the number of inlets and outlets 2 on one inner cavity; a first driving rod 7 is rotatably connected to each of the three inner cavity positions on the connecting frame 6; a rotating mechanism is provided on the rotating ring 3, which is used to drive the rotating ring 3 to rotate;

[0040] The rotating mechanism includes four second drive rods 8, which are arranged in a circular array on the rotating ring 3 and are all fixedly connected to the rotating ring 3; the first drive rod 7 is located below the side of the rotating ring 3 and two of the second drive rods 8 are located directly above the first drive rod 7.

[0041] A first stop 9 is fixedly connected to the first drive rod 7, and a second stop 10 is provided above the first stop 9. The first stop 9 and the second stop 10 are in contact with each other, and the second stop 10 is fixedly connected to the connecting frame 6. A stop rod 11 is provided at a position diagonally opposite to the first drive rod 7 on the rotating ring 3. The stop rod 11 is slidably connected to the reef 1, and the stop rod 11 is in contact with the second drive rod 8 located diagonally above the rotating ring 3.

[0042] During operation, when the first sliding frame 5 is driven to move upward, it drives multiple connecting frames 6 to move upward simultaneously. Each connecting frame 6 then drives three connected first drive rods 7 to move upward. During this upward movement, each first drive rod 7 contacts a second drive rod 8 and pushes it upward. This upward movement of the second drive rod 8 causes the connected rotating ring 3 to rotate. When the first drive rod 7 moves upward to a position where it disengages from the second drive rod 8, the rotating ring 3 rotates exactly ninety degrees. When the first sliding frame 5 is driven to slide downward and reset, the first drive rod 7... The first drive rod 7 will move downwards and will come into contact with the second drive rod 8 located below it during the downward movement. At this time, since one of the second drive rods 8 is blocked by the stop rod 11, the rotating ring 3 cannot rotate in the opposite direction. Therefore, the second drive rod 8 remains stationary. When the first drive rod 7 comes into contact with the second drive rod 8, the first drive rod 7 will rotate upwards relative to the connecting frame 6. When the first drive rod 7 rotates upwards at a certain angle, the first drive rod 7 will pass over the second drive rod 8. After the first drive rod 7 passes over the second drive rod 8, the first drive rod 7 will automatically reset under its own gravity.

[0043] like Figure 4-10 As shown, as a further embodiment of the present invention, the discharge mechanism includes a drainage cylinder 12, which is located at the center of the reef body 1 and is fixedly connected to the reef body 1; four partitions 13 are fixedly connected inside the drainage cylinder 12, and the three inner cavities formed by the four partitions 13 are respectively flush with the three inner cavities inside the reef body 1; four drainage ports 14 are provided on the outer side of each inner cavity of the drainage cylinder 12, and the drainage ports 14 are connected to the inner cavity inside the drainage cylinder 12 and are provided with sealing caps 15, which are rotatably connected to the drainage ports 14; a drainage mechanism is provided inside the inner cavity of the drainage cylinder 12, which is used to discharge the water in the inner cavity of the drainage cylinder 12 into the inner cavity of the reef body 1 through the four drainage ports 14;

[0044] The drainage mechanism includes three drainage plates 16, which are located in three cavities within the drainage cylinder 12. The drainage plates 16 are fitted with the inner wall of the drainage cylinder 12 with a clearance and are made of solid metal. A second sliding frame 17 is provided inside the drainage cylinder 12. The second sliding frame 17 is slidably connected to the three upper partitions 13 and is also fixedly connected to the three drainage plates 16. An opening and closing mechanism is provided inside the drainage cylinder 12, which is used to drive the four sealing caps 15 corresponding to the cavity to open and close.

[0045] The opening and closing mechanism includes four fixed rods 18, which are arranged in a circular array within the inner cavity of the drain cylinder 12. The upper and lower ends of each fixed rod 18 are fixedly connected to the upper and lower partition plates 13 on either side. The drain plate 16 is clearance-fitted to the four fixed rods 18. A sliding ring 19 is slidably connected to each fixed rod 18, and a connecting rod 20 is rotatably connected to the sliding ring 19. The end of the connecting rod 20 away from the sliding ring 19 is rotatably connected to the sealing cover 15. A first locking block 21 is rotatably connected to the sliding ring 19 on the side away from the connecting rod 20. A second locking block 22 is located above the first locking block 21 and is fixedly connected to the fixed rod 18. A first pull rope 23 is fixedly connected to the first locking block 21 away from the locking end, and the bottom end of the first pull rope 23 is fixedly connected to the drain plate 16. A torsion spring is located on the first locking block 21 at the connection point with the sliding ring 19.

[0046] The drainage cylinder 12 is equipped with a water pipe 24, which passes through the three upper partitions 13 and the three drainage plates 16. The bottom end of the water pipe 24 is located between the lower partition 13 and the lower drainage plate 16. The water pipe 24 is fixedly connected to the partition 13 and the water pipe 24 is clearance-fitted with the drainage plate 16. An opening is provided on the water pipe 24 between the drainage plate 16 and the partition 13.

[0047] A sealing plate 25 is fixedly connected to the bottom of the first sliding frame 5, and the sealing plate 25 is attached to the upper end of the water pipe 24; the second sliding frame 17 is in clearance fit with the sealing plate 25; a second pull rope 26 is fixedly connected to the upper end of the first sliding frame 5, a pull ring 27 is fixedly connected to the upper end of the second pull rope 26, and a float 28 is sleeved on the second pull rope 26, with the float 28 in clearance fit with the second pull rope 26.

[0048] During operation, by pulling the pull ring 27 upward, the pull ring 27 pulls the first sliding frame 5 upward via the second pull rope 26. The first sliding frame 5 first drives the first drive rod 7 upward via the connecting frame 6. The first drive rod 7 then drives the rotating ring 3 to rotate via the second drive rod 8 to clean the deposits on the inlet and outlet 2. At the same time as the first sliding frame 5 moves upward, it also drives the sealing plate 25 upward, and the sealing plate 25 disengages from the upper end of the water pipe 24. When the first drive rod 7 moves upward to the position where it disengages from the second drive rod 8, the sealing plate 25 moves to the position where it fits against the second sliding frame 17.

[0049] As the first sliding frame 5 continues to move upward, the second sliding frame 17 also begins to move upward. The second sliding frame 17 drives the three drainage plates 16 connected to it to move upward. The drainage plates 16 then begin to squeeze the water in the inner cavity of the drainage cylinder 12. After being squeezed, the water in the inner cavity of the drainage cylinder 12 will push open the sealing cover 15 and be discharged into the inner cavity of the reef body 1 through the drainage port 14. The water in the inner cavity of the reef body 1 will be discharged through the inlet and outlet 2. The discharged water will also discharge the blockage remaining in the inlet and outlet 2.

[0050] After the sealing cover 15 is squeezed open, the sealing cover 15 will start to rotate upward. When the sealing cover 15 rotates upward, it will pull the sliding ring 19 upward through the connecting rod 20. The sliding ring 19 will drive the first locking block 21 to move upward. When the sealing cover 15 is fully opened, the first locking block 21 will just move to the position where it engages with the second locking block 22.

[0051] When the drainage plate 16 moves to the position near the drain outlet 14 inside the drainage cylinder 12, the pull ring 27 can be released, and the drainage plate 16 will fall automatically. When the drainage plate 16 falls, it will draw the water in the reef 1 cavity back into the drainage cylinder 12 cavity through the drain outlet 14. When the drainage plate 16 falls to the bottom of the cavity, it will straighten the first pull rope 23 and pull the first locking block 21 to rotate. When the first locking block 21 rotates, it will disengage from the second locking block 22. At this time, the sliding ring 19 will start to fall, and the sealing cover 15 will gradually close. After the sealing cover 15 closes, it can effectively prevent benthic animals in the reef 1 cavity from entering the drainage cylinder 12 cavity.
