Combined ecological fish reef for river and lake sand mining area benthic habitat restoration

Abstract

The application discloses a combined ecological fish reef for river and lake sand mining area benthic habitat restoration in the technical field of artificial fish reefs, which comprises a bottom rod and further comprises a supporting rod located inside the bottom rod and in sliding connection with the bottom rod, and a first fixing rod embedded outside the supporting rod and in rotary connection with the supporting rod. The combined fish reef design can facilitate the taking out and launching of the fish reef. After launching, the fish reef provides a habitat for fish. After taking out, the fish reef provides convenience for the harvesting and fishing of fish. After folding, the fish reef is in the form of a plate, which facilitates stacking, storage and transportation. When taking out, the first fixing rod is lifted to make the supporting rod slide along the bottom rod, so that the fish reef is folded and the lower frame is gradually separated from the water bottom, and then the fish reef is taken out, which facilitates the separation of the whole fish reef from the water bottom.

Description

Technical Field

[0001] This invention relates to the field of artificial reef technology, specifically a combined ecological reef for the restoration of benthic habitats in river and lake sand mining areas. Background Technology

[0002] Artificial reefs are hydraulic structures suitable for aquatic organisms and fish to congregate, grow, and reproduce. They mainly provide a good habitat and foraging and breeding grounds for aquatic organisms and fish.

[0003] For water source areas such as rivers and lakes, aquaculture areas are usually divided into sections or regions for fish farming and promoting fish reproduction. During the fish farming season, artificial reefs are placed to allow fish to gather, inhabit, grow, and reproduce. During the harvest season, in order to facilitate netting and prevent the presence of artificial reefs from reducing harvesting efficiency, artificial reefs are usually removed from the water to facilitate the harvesting of large fish. This means that artificial reefs need to be removed and placed at specific times. However, most existing artificial reefs are made of concrete that has been directly deposited to the bottom of the water, making them difficult to remove and place and inconvenient to transport. Summary of the Invention

[0004] The purpose of this invention is to provide a combined ecological fish reef for the restoration of benthic habitats in river and lake sand mining areas, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a combined ecological fish reef for the restoration of benthic habitats in river and lake sand mining areas, comprising a base rod, and further comprising: a support rod located inside the base rod and slidably connected to the base rod; a first fixed rod embedded outside the support rod and rotatably connected to the support rod; a second fixed rod located below the first fixed rod and fixedly connected to the base rod; two upper frames symmetrically distributed on the left and right sides of the first fixed rod, with their top ends rotatably connected to the first fixed rod; two middle frames rotatably located at the bottom of the two upper frames; two lower frames rotatably connected at their bottom ends to the second fixed rod, with their top ends rotatably connected to the two middle frames; a limiting groove, U-shaped and formed along the inner wall of the base rod; and a fixed end located above the inside of the limiting groove and fixedly connected to the support rod.

[0006] As a further embodiment of the present invention, a pick-and-place assembly is provided on the support rod, the pick-and-place assembly comprising: a fixed block, T-shaped and fixedly connected to the top of the support rod; two baffles, both fixedly connected to the inner wall of the support rod and the fixed block; two pressure plates, slidably connected to the baffles, each with a first spring fixedly connected to its bottom between the pressure plate and the baffle; a sliding groove, opened along the trajectory of the support rod; a locking member, slidably connected to the pressure plate, the locking member being located within the sliding groove and fixedly connected to the inner wall of the support rod; a working rod, located on the support rod; two clamps, symmetrically distributed and horizontally sliding on both sides of the bottom end of the working rod, the bottom ends of the clamps being wedge-shaped; and two second springs, respectively fixedly connected between the clamps and the working rod. When the clamps press down on the pressure plate, the contact between the clamps and the fixed block allows the clamps to slide along the working rod. After the clamps descend below the fixed block, the second springs push the clamps to grip the fixed block.

[0007] The trigger group is used to actively drive the two cards to slide along the working rod.

[0008] As a further embodiment of the present invention, the trigger group includes a slider and two support rods. The slider is slidably connected to the working rod, the top ends of the two support rods are rotatably connected to the slider, and the bottom ends of the two support rods are rotatably connected to two clips respectively.

[0009] As a further embodiment of the present invention, an alignment rod is fixedly connected to the fixing block, and an alignment hole is provided at the bottom end of the working rod.

[0010] As a further embodiment of the present invention, a traction rope is fixedly connected to the alignment rod, a buoy is fixedly connected to the traction rope, and a lead wire hole is fixedly connected to the working rod.

[0011] As a further embodiment of the present invention, the upper frame, middle frame and lower frame are all provided with perforations and perching holes.

[0012] As a further embodiment of the present invention, the sidewalls of the upper frame are provided with ecological grass.

[0013] As a further embodiment of the present invention, the bottom end of the base rod is tapered.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention, through its modular reef design, facilitates the removal and deployment of the reef. After deployment, it provides a habitat for fish, and after removal, it facilitates the harvesting and catching of fish. The reef, when folded, is plate-shaped, making it easy to stack, store, and transport. When removing the reef, the first fixing rod is lifted, causing the support rod to slide up along the bottom rod, thus folding the reef and allowing the lower frame to gradually detach from the seabed before removal. This facilitates the overall detachment of the reef from the seabed.

[0016] The locking mechanism and pressure plate restrict the support rod from rotating, thus preventing accidental contact that could cause the fixed end to detach from the top of the limiting groove. This also prevents the reef from unfolding before deployment, which would affect deployment and transportation. When removing the reef, the working rod allows it to be folded into a plate shape before being lifted, facilitating retrieval and placement. Attached Figure Description

[0028] Please see Figures 1-10 This invention provides a technical solution: a combined ecological fish reef for the restoration of benthic habitats in river and lake sand mining areas, comprising a base rod 1, and further comprising: a support rod 2, located inside the base rod 1 and slidably connected to the base rod 1; a first fixing rod 3, embedded outside the support rod 2 and rotatably connected to the support rod 2; a second fixing rod 4, located below the first fixing rod 3 and fixedly connected to the base rod 1; two upper frames 5, symmetrically distributed on the left and right sides of the first fixing rod 3, with their top ends rotatably connected to the first fixing rod 3; two middle frames 6, respectively rotatably located at the bottom of the two upper frames 5; two lower frames 7, their bottom ends rotatably connected to the second fixing rod 4, with their top ends rotatably connected to the two middle frames 6; a limiting groove 8, U-shaped and opened along the inner wall of the base rod 1; and a fixed end 9, located inside and above the limiting groove 8 and fixedly connected to the support rod 2.

[0029] like Figure 1 , 2 Figure 5 and Figure 6 As shown:

[0030] Artificial reef deployment:

[0031] Before deployment, the fixed end 9 is positioned above the limiting groove 8. Since the limiting groove 8 is U-shaped, for ease of reference, the horizontal part above the limiting groove 8 is listed as a, the vertical part in the middle of the limiting groove 8 is listed as b, and the horizontal part below the limiting groove 8 is listed as c.

[0032] That is, the artificial reef was in a state of... before deployment Figure 1 As shown in the diagram, the fixed end 9 is inside a, and the reef is plate-shaped, which facilitates transportation and storage. During deployment, the reef is transported to the designated waters by the hull and then straightened. Since the fixed end 9 is inside a, the support rod 2 will not slide along the bottom rod 1. Therefore, the support rod 2 needs to be rotated to rotate the fixed end 9 to the top of b. At this time, the support rod 2 rotates inside the first fixed rod 3. After the fixed end 9 is rotated to the top of b, the support rod 2 slides down the bottom rod 1, causing the upper frame 5, middle frame 6, and lower frame 7 to unfold into a rectangle above the first fixed rod 3 and the second fixed rod 4, thus forming the reef. Then, the support rod 2 is rotated again to allow the fixed end 9 to enter c. At this time, the reef is fixed after being shaped, and then it can be directly put into the water.

[0033] Then, the remaining artificial reefs are operated in the same manner as described above, thereby providing a habitat and hiding structure for fish and benthic organisms;

[0034] Artificial reef removal work:

[0035] When the fish reach harvest time, lift the reef out of the water and then rotate the support rod 2 to rotate the fixed end 9 from c to b. Then lift the first fixed rod 3 to make the support rod 2 slide up along the bottom rod 1 until the fixed end 9 slides up into a. Then rotate the support rod 2 to make the fixed end 9 enter into a. At this time, the reef will become plate-shaped again. Then continue to lift it to separate the bottom rod 1 and the second fixed rod 4 from the bottom of the water. By first folding and then lifting, it is easy to take out the reef as a whole, stack it for storage and transportation.

[0036] Once all the artificial reefs have been removed, there will be no obstacles in the water that will block the seine net. You can then choose a net with a suitable mesh size according to the size of the fish you want to harvest. Smaller fish can escape through the mesh during harvesting. After harvesting, simply put the fish back into the artificial reef.

[0037] This invention, through its modular reef design, facilitates the removal and deployment of the reef. After deployment, it provides a habitat for fish, and after removal, it facilitates the harvesting and catching of fish. The reef, when folded, is plate-shaped, making it easy to stack, store, and transport. When removing the reef, the first fixing rod 3 is lifted, causing the support rod 2 to slide up along the bottom rod 1, which folds the reef and allows the lower frame 7 to gradually detach from the bottom of the water before removal. This facilitates the overall detachment of the reef from the bottom of the water.

[0038] A pick-and-place assembly is provided on the support rod 2, comprising: a T-shaped fixing block 10 fixedly connected to the top of the support rod 2; two baffles 11 fixedly connected to the inner wall of the support rod 2 and the fixing block 10; two pressure plates 12 slidably connected to the baffles 11, with a first spring 13 fixedly connected to their bottoms and the baffles 11; a sliding groove 14 opened along the trajectory of the support rod 2; and a locking member 15 slidably connected to the pressure plates 12, located within the sliding groove 14 and fixedly connected to the inner wall of the support rod 2. Rod 16 is located above support rod 2; two clamps 17 are symmetrically distributed and slide horizontally on both sides of the bottom end of working rod 16, and the bottom end of each clamp 17 is wedge-shaped; two second springs 18 are fixedly connected between the clamps 17 and working rod 16 respectively. When the clamps 17 press down on the pressure plate 12, the clamps 17 can slide along the working rod 16 through contact with the fixed block 10. After the clamps 17 descends below the fixed block 10, the second springs 18 will push the clamps 17 to hold the fixed block 10 tightly.

[0039] The trigger group is used to actively drive the two card pieces 17 to slide along the working rod 16.

[0040] like Figure 3 , Figures 5-9 As shown:

[0041] The deployment and retrieval of the artificial reefs are facilitated by the deployment and retrieval system.

[0042] Distribution efforts:

[0043] Before deployment, the pressure plate 12 is positioned between the baffles 11. At this time, the baffles 11, the pressure plate 12, and the top of the fixing block 10 are at the same horizontal level. The pressure plate 12 is located outside the locking member 15. Because the locking member 15 is fixedly connected to the first fixing rod 3, when the locking member 15 is inside the pressure plate 12, it restricts the position of the baffles 11 and the pressure plate 12, thus preventing the support rod 2 from rotating inside the first fixing rod 3. In other words, the reef cannot unfold. When the reef cannot unfold, it ensures that it maintains a plate-like shape during transportation and stacking, preventing accidental rotation of the support rod 2 inside the first fixing rod 3. After the artificial reef is transported to the designated area, the two latches 17 at the bottom of the working rod 16 are aligned with the two pressure plates 12, and the pressure plates 12 are pushed so that they can slide along the baffle 11. At this time, the first spring 13 will be compressed. Because the bottom end of the latch 17 is wedge-shaped, the latch 17 will slide along the bottom of the working rod 16 and compress the second spring 18. Then the pressure plate 12 will descend relative to the locking part 15. When the pressure plate 12 descends to its limit, the latch 17 will move under the action of the second spring 18 and clamp the fixing block 10. At this time, the working rod 16 and the undeployed artificial reef will become a whole. Figure 9 In the state shown, the clip 17 will be in the gap between the two baffles 11, and the locking piece 15 will also release the restriction on the pressure plate 12.

[0044] Then, the plate-shaped reef is directly thrown into the water. At this time, the bottom of the working rod 16 will also be submerged in the water. When the second fixed rod 4 contacts the bottom of the water, the working rod 16 is rotated. At this time, the working rod 16 will drive the baffle 11 and the support rod 2 to rotate inside the first fixed rod 3. At this time, the slide 14 will rotate relative to the locking part 15. Then, the fixed end 9 will rotate from part a of the limiting groove 8 to directly above part b, and the pressure plate 12 will also rotate below the locking part 15. Then, the support rod 2 will follow the fixed end 9 as it descends inside part b and slides down along the bottom rod 1 to the bottom. At this time, the upper frame 5, the middle frame 6 and the lower frame 7 will unfold into a rectangle, which becomes the reef. Then, the working rod 16 is rotated in the opposite direction to make the fixed end 9 rotate from inside part b to inside part c.

[0045] Then, the trigger group drives the two locking pieces 17 to slide along the bottom of the working rod 16 to both sides and compress the second spring 18. At this time, the two locking pieces 17 will keep pressing down on the pressure plate 12 while moving away from each other. When the bottom end of the locking piece 17 moves to both sides of the fixing block 10, the working rod 16 is lifted up until it is separated from the support rod 2. At this time, the pressure plate 12 will slide up under the elastic action of the first spring 13 and overlap with the locking piece 15. At this time, the locking piece 15 restricts the pressure plate 12 so that the pressure plate 12 and the support rod 2 cannot rotate, thereby completing the locking of the unfolded reef.

[0046] Artificial reef removal work:

[0047] Sailing over the deployed reef, align the locking piece 17 at the bottom of the working rod 16 with the pressure plate 12 again and press down on the pressure plate 12. At this time, the locking piece 17 will lock the fixing block 10 again. Then rotate the working rod 16 to drive the support rod 2 and the fixed end 9 to rotate. When the fixed end 9 rotates from c to b, lift the working rod 16. At this time, the working rod 16 will complete the rise of the support rod 2 and the first fixed rod 3 through the locking piece 17 and the fixing block 10, so that the upper frame 5, the middle frame 6 and the lower frame 7 can be folded. When the fixed end 9 slides to the top of b, rotate the working rod 16 to move the fixed end 9 to a. At this time, the initial fixation after the reef is folded is completed. Then, pull the support rod 2 upward directly through the working rod 16 to complete the separation of the second fixed rod 4 from the bottom of the water. After the reef is pulled onto the boat, the two locking pieces 17 can be separated from the fixing block 10 by triggering the group.

[0048] The locking element 15 and the pressure plate 12 lock the support rod 2 so that it cannot rotate, thereby preventing accidental contact that could cause the fixed end 9 to detach from the top of the limiting groove 8. This also prevents the reef from unfolding before deployment, which would affect the deployment and transportation work. When the reef is removed, the working rod 16 can be used to fold the reef into a plate shape before it is lifted, which makes it easier to pick up and place it after lifting.

[0049] The trigger assembly includes a slider 27 and two support rods 19. The slider 27 is slidably connected to the working rod 16. The top ends of the two support rods 19 are rotatably connected to the slider 27, and the bottom ends of the two support rods 19 are rotatably connected to two clips 17 respectively.

[0050] like Figure 5 , Figure 6 as well as Figure 9 and Figure 10 As shown:

[0051] When it is necessary to release the locking piece 17 from the fixing block 10, slide the slide plate 27 downward. At this time, the support rod 19 will push the two locking pieces 17 away from the fixing block 10. When the locking piece 17 is no longer in contact with the fixing block 10, the working rod 16 can be lifted directly to release the locking piece 17 from the fixing block 10.

[0052] A positioning rod 20 is fixedly connected to the fixed block 10, and a positioning hole 21 is opened at the bottom end of the working rod 16.

[0053] A traction rope 22 is fixedly connected to the alignment rod 20, a float 23 is fixedly connected to the traction rope 22, and a lead wire hole 24 is fixedly connected to the working rod 16.

[0054] like Figure 1 , Figure 3 , Figure 5 , Figure 6 as well as Figure 10 As shown:

[0055] Since the artificial reef is submerged in water after deployment, the water level is higher than the first fixed rod 3. This allows for unimpeded navigation on the water and facilitates the positioning of the artificial reef when it needs to be removed. The position of the artificial reef is indicated by the towing rope 22 and the buoy 23 floating on the water surface. When the artificial reef needs to be removed, the position of the artificial reef is determined by the direction of the buoy 23. Then, the lead hole 24 is fitted onto the towing rope 22, and the lead hole 24 is kept in contact with the towing rope 22 when the working rod 16 is inserted into the water. When the working rod 16 moves to the bottom of the towing rope 22, it will contact the support rod 2. At this time, the alignment hole 21 and the alignment rod 20 are aligned by the tactile feeling when holding the working rod 16. The alignment rod 20 enters the interior of the alignment hole 21 to position the working rod 16, making the working rod 16 coaxial with the support rod 2.

[0056] At this time, the locking piece 17 will contact the baffle 11 or the pressure plate 12. At this time, the working rod 16 can be rotated while pressing down. When the locking piece 17 rotates to coincide with the pressure plate 12, the locking piece 17 will directly press down on the pressure plate 12, causing the pressure plate 12 to slide down. At this time, the positioning of the locking piece 17 and the pressure plate 12 is completed. Then, the working rod 16 can be rotated so that the working end rotates from c to b and then lifted up to complete the folding of the reef. Then it can be taken out.

[0057] The upper frame 5, the middle frame 6 and the lower frame 7 are all provided with perforations 25 and perching holes 26.

[0058] like Figure 1 and Figure 2 As shown:

[0059] The perching holes 26 and perforations 25 facilitate the entry and exit of bottom organisms and provide them with habitats and hiding places.

[0060] The upper frame has five side walls covered with ecological grass.

[0061] Ecological grass can be one or more components of existing technologies, such as carbon fiber ecological grass or other types of pre-bonded ecological grass, which can simulate a real ecological environment after the artificial reef is deployed. Specific details will not be elaborated here.

[0062] The bottom end of the base rod 1 is tapered.

[0063] like Figure 1 As shown:

[0064] The tapered base rod 1 can be easily inserted directly into the bottom of the water, providing a more stable placement position after deployment.

[0065] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
