Description

Technical Field

[0001] This utility model relates to the field of coral protection tools, specifically to an underwater biological resource protection cover. Background Technology

[0002] Coral reefs are an important component of marine ecosystems, providing habitats for numerous marine organisms and maintaining marine biodiversity. However, the presence of large predatory fish in coral reef areas can alter the fish community structure, thus impacting the reefs themselves. Therefore, the current practice is to install protective covers around the reefs to isolate them from the outside world and protect them. These covers typically consist of a framework attached to the reef with protective netting. While this method provides isolation, the fixed mesh size of the netting prevents certain organisms of specific sizes from adapting and surviving within the reef, leading to biodiversity loss and potentially affecting the stability and resilience of the coral reef ecosystem. Utility Model Content

[0003] This invention provides an underwater biological resource protection cover that can overcome some or all the defects of the prior art.

[0004] According to the present invention, an underwater biological resource protective cover includes: a rectangular protective cover body, the protective cover body including support members disposed at the four corners of the protective cover body; a baffle assembly for connecting adjacent support members; the baffle assemblies between adjacent support members together form a protection zone; a protective net for sealing the protection zone is provided above the support members; a first through hole for fish to pass through is provided at the baffle assembly, and an adjustment mechanism for adjusting the size of the first through hole is provided at the first through hole.

[0005] With this invention, when installing the main body of the protective cover underwater, installers first arrange four support components along the perimeter of the coral reef. While arranging the support components, installers insert the support feet at the lower end of the column into the seabed sand for fixation. Then, they connect the baffle assembly to the column. When connecting the baffle assembly to the column, the first limiting plate at one end of the sub-baffle is inserted into the second limiting groove on the column, with an interference fit between the first limiting plate and the second limiting groove. Next, the second limiting plate on the column is inserted into the first limiting groove on another sub-baffle, with an interference fit between the first limiting groove and the second limiting plate. This connects the column to the sub-baffle. Then, installers connect the sub-baffles sequentially, with an interference fit between the first limiting plate and the first limiting groove on each sub-baffle. After the sub-baffles are connected, the installers adjust the size of the first through hole on the baffle assembly using the adjustment mechanism. The installers can set the size of the first through hole according to the size of the predatory fish in the current sea area and the size of the small fish living in the coral reef. After the size of the first through hole is determined, the installers insert the limiting posts on the two second connecting plates into the corresponding limiting holes. Then, they align the second through hole on the first connecting plate with the first threaded hole. Finally, they connect the first connecting plate to the first guide plate by passing bolts through the second through hole and the first threaded hole. This makes the size of the first through hole formed between the two second connecting plates and the two first connecting plates large enough for small fish living in the coral reef to pass through, while preventing large carnivorous fish from passing through.

[0006] When the size of the first through hole needs to be adjusted again, simply change the connection positions of the two first connecting plates and the two second connecting plates with the first threaded hole and the limiting hole to adjust the size of the first through hole. By adjusting the size of the first through hole, the types and sizes of organisms entering the coral reef protective cover can be effectively controlled. Smaller mesh openings can prevent fish or other organisms that may damage the coral reef from entering, thereby protecting the integrity and stability of the coral reef ecosystem. At the same time, the size of the first through hole can be flexibly adjusted according to actual needs. For example, in different seasons or under different ecological conditions, the size of the first through hole can be adjusted according to the growth of the coral reef and the biological activity patterns to adapt to changes in the coral reef ecosystem.

[0007] After the sub-baffles are connected, the installers will lay the protective net over the protected area to cover the coral reef and prevent large predatory fish from entering the coral reef from above the protective cover.

[0008] Preferably, the baffle assembly includes multiple sub-baffles connected in sequence. Each sub-baffle includes two parallel horizontal plates and two parallel vertical plates. The two horizontal plates and two vertical plates are connected end to end in sequence to form an installation frame. One end of the installation frame is provided with a first limiting plate arranged along the length of the vertical plate, and the other end is provided with a first limiting groove into which the first limiting plate extends.

[0009] The support includes a column with a rectangular cross-section, and a second limiting groove is provided on the side wall of the column for the first limiting plate to extend into; a second limiting plate is provided on the side wall of the column adjacent to the second limiting groove, extending into the first limiting groove.

[0010] With this utility model, since the sub-baffles and the uprights are connected by splicing, and adjacent sub-baffles are also connected by splicing, it is convenient for installers to install the protective cover; at the same time, installers can splice different numbers of sub-baffles according to the size of the coral reef area, and finally form a protective cover that is suitable for different coral reef areas.

[0011] The first limiting plate and the second limiting groove are interference-fitted, as are the first limiting groove and the second limiting plate. The first limiting plate and the first limiting groove on the sub-baffle are also interference-fitted, so that when the installer connects the sub-baffle to the column, the sub-baffle can be fixed on the column and not move, which makes it convenient for the installer to connect multiple sub-baffles later.

[0012] Preferably, the mounting frame is provided with a first guide plate arranged along the length of the horizontal plate and a second guide plate arranged along the length of the vertical plate; the first guide plate is provided with a plurality of first threaded holes spaced apart along the length of the first guide plate, and the second guide plate is provided with a plurality of limiting holes spaced apart along the length of the second guide plate; the first guide plate presses on top of the second guide plate.

[0013] The adjustment mechanism includes two first connecting plates for connecting the first guide plate and two second connecting plates for connecting the second guide plate; each of the first connecting plates has a second through hole at both ends, and bolts pass through the second through holes and the first threaded holes to connect the first connecting plate and the first guide plate; each of the second connecting plates has a limiting post passing through the limiting hole at both ends.

[0014] With this invention, since the first guide plate is pressed on top of the second guide plate, there is a height difference between the first guide plate and the second guide plate. Therefore, after the installer inserts the limiting post on the second connecting plate into the limiting hole on the second guide plate, the first connecting plate is pressed on the second connecting plate. Then, the second connecting plate can be fixed together by fixing the first connecting plate with bolts, thereby saving the installer's installation time.

[0015] Preferably, the upper end of the column is provided with a second threaded hole; a limiting member for fixing the protective net is provided above the column, the limiting member includes a threaded post for extending into the second threaded hole, the upper end of the threaded post is provided with a first disc, the end of the first disc is provided with a pole passing through the protective net, and the upper end of the pole is provided with a second disc.

[0016] With this invention, when installing the protective net, the installer first screws the threaded post into the second threaded hole at the top of the column, then unfolds the protective net so that the four corners of the net are hung on the column. The column then fixes the four corners of the net, and the second disc above the column prevents the net from moving up and detaching from the column.

[0017] Preferably, the lower end of the column is provided with a cone-shaped support foot.

[0018] With this invention, the support feet are cone-shaped, making it easy for installers to insert them into the seabed mud.

[0019] Preferably, the columns, protective netting, support legs, mounting frame, first connecting plate, and second connecting plate are all made of stainless steel.

[0020] This invention provides a stainless steel structure with high strength, which can extend the service life of the protective cover. Attached Figure Description

[0030] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0031] Example 1

[0032] like Figure 1-9 As shown, this embodiment provides an underwater biological resource protective cover, including a rectangular protective cover body 100. The protective cover body 100 includes support members 110 disposed at the four corners of the protective cover body 100; baffle assemblies for connecting adjacent support members 110 are provided between adjacent support members 110; the baffle assemblies between adjacent support members 110 together form a protection zone; a protective net 120 for sealing the protection zone is provided above the support members 110; a first through hole 210 for fish to pass through is provided at the baffle assembly, and an adjustment mechanism for adjusting the size of the first through hole 210 is provided at the first through hole 210.

[0033] In this embodiment, when installing the protective cover body 100 underwater, the installer first arranges the four support members 110 along the periphery of the coral reef. While arranging the support members 110, the installer inserts the support feet 230 at the lower end of the column 330 into the seabed sand for fixation. Then, the baffle assembly is connected to the column 330. When connecting the baffle assembly to the column 330, the first limiting plate 720 at one end of the sub-baffle 130 is inserted into the second limiting groove on the column 330. Within 310, the first limiting plate 720 and the second limiting groove 310 are interference-fitted; then, the second limiting plate 320 on the column 330 is inserted into the first limiting groove 770 on another sub-baffle 130, with the first limiting groove 770 and the second limiting plate 320 being interference-fitted; thus connecting the column 330 and the sub-baffle 130; then, the installers connect the sub-baffles 130 sequentially, with the first limiting plate 720 on the sub-baffle 130 being interference-fitted with the first limiting groove 770. The grooves 770 are interference-fitted. After the sub-baffles 130 are connected, the installer adjusts the size of the first through hole 210 on the baffle assembly through the adjustment mechanism. The installer can set the size of the first through hole 210 according to the size of the predatory fish in the current sea area and the size of the small fish living in the coral reef. After the size of the first through hole 210 is determined, the installer inserts the limiting pins 910 on the two second connecting plates 740 into the corresponding limiting holes 730. Then, the second through hole 820 on the first connecting plate 702 is aligned with the first threaded hole 780. Finally, the first connecting plate 702 is connected to the first guide plate 790 by passing the bolt 701 through the second through hole 820 and the first threaded hole 780. The size of the first through hole 210 formed between the two second connecting plates 740 and the two first connecting plates 702 is large enough for small fish living in the coral reef to pass through, while preventing large carnivorous fish from passing through.

[0034] When the size of the first through hole 210 needs to be adjusted again, simply change the connection positions of the two first connecting plates 702 and the two second connecting plates 740 with the first threaded hole 780 and the limiting hole 730 to adjust the size of the first through hole 210. By adjusting the size of the first through hole 210, the types and sizes of organisms entering the coral reef protective cover can be effectively controlled. Smaller mesh openings can prevent fish or other organisms that may damage the coral reef from entering, thereby protecting the integrity and stability of the coral reef ecosystem. At the same time, the size of the first through hole 210 can be flexibly adjusted according to actual needs. For example, in different seasons or under different ecological conditions, the size of the first through hole 210 can be adjusted according to the growth of the coral reef and the biological activity patterns to adapt to changes in the coral reef ecosystem.

[0035] After the sub-baffle 130 is connected, the installers will lay the protective net 120 over the protected area to cover the coral reef and prevent large carnivorous fish from entering the coral reef from above the protective cover.

[0036] In this embodiment, the baffle assembly includes a plurality of sub-baffles 130 connected in sequence. Each sub-baffle 130 includes two parallel horizontal plates 710 and two parallel vertical plates 750. The two horizontal plates 710 and the two vertical plates 750 are connected end to end in sequence to form an installation frame. One end of the installation frame is provided with a first limiting plate 720 arranged along the length direction of the vertical plate 750, and the other end is provided with a first limiting groove 770 into which the first limiting plate 720 extends.

[0037] The support member 110 includes a column 330 with a rectangular cross-section. The side wall of the column 330 is provided with a second limiting groove 310 into which the first limiting plate 720 extends. The side wall of the column 330 adjacent to the second limiting groove 310 is provided with a second limiting plate 320 that extends into the first limiting groove 770.

[0038] In this embodiment, since the sub-baffle 130 and the column 330 are connected by splicing, and adjacent sub-baffles 130 are also connected by splicing, it is convenient for installers to install the protective cover. At the same time, installers can splice different numbers of sub-baffles 130 according to the size of the coral reef area, and finally form a protective cover that is suitable for different coral reef area sizes.

[0039] The first limiting plate 720 and the second limiting groove 310 are interference-fitted, the first limiting groove 770 and the second limiting plate 320 are interference-fitted, and the first limiting plate 720 and the first limiting groove 770 on the sub-baffle 130 are interference-fitted, so that when the installer connects the sub-baffle 130 to the column 330, the sub-baffle 130 can be fixed on the column 330 and not move, which facilitates the installer to connect multiple sub-baffles 130 later.

[0040] In this embodiment, the mounting frame is provided with a first guide plate 790 arranged along the length of the horizontal plate 710 and a second guide plate 760 arranged along the length of the vertical plate 750; the first guide plate 790 is provided with a plurality of first threaded holes 780 spaced apart along the length of the first guide plate 790, and the second guide plate 760 is provided with a plurality of limiting holes 730 spaced apart along the length of the second guide plate 760; the first guide plate 790 presses on the second guide plate 760.

[0041] The adjustment mechanism includes two first connecting plates 702 for connecting the first guide plate 790 and two second connecting plates 740 for connecting the second guide plate 760. Each of the two ends of the first connecting plate 702 is provided with a second through hole 820, and a bolt 701 passes through the second through hole 820 and the first threaded hole 780 to connect the first connecting plate 702 and the first guide plate 790. Each of the two ends of the second connecting plate 740 is provided with a limiting post 910 passing through a limiting hole 730.

[0042] In this embodiment, since the first guide plate 790 presses on top of the second guide plate 760, there is a height difference between the first guide plate 790 and the second guide plate 760. Therefore, after the installer inserts the limiting post 910 on the second connecting plate 740 into the limiting hole 730 on the second guide plate 760, and then presses the first connecting plate 702 on the second connecting plate 740, the second connecting plate 740 can be fixed together by fixing the first connecting plate 702 with bolts 701, thereby saving the installer's installation time.

[0043] In this embodiment, the upper end of the column 330 is provided with a second threaded hole 410; a limiting member 220 for fixing the protective net 120 is provided above the column 330. The limiting member 220 includes a threaded post 540 for extending into the second threaded hole 410. The upper end of the threaded post 540 is provided with a first disc 530. The end of the first disc 530 is provided with a pole 520 that passes through the protective net 120. The upper end of the pole 520 is provided with a second disc 510.

[0044] In this embodiment, when installing the protective net 120, the installer first screws the threaded post 540 into the second threaded hole 410 at the upper end of the column 330, and then unfolds the protective net 120 so that the four corners of the protective net 120 are hung on the column 520. The column 520 fixes the four corners of the protective net 120, and the second disc 510 above the column 520 prevents the protective net 120 from moving upward and detaching from the column 520.

[0045] In this embodiment, the lower end of the column 330 is provided with a cone-shaped support foot 230.

[0046] In this embodiment, the support foot 230 is cone-shaped, which makes it easy for installers to insert the support foot 230 into the seabed mud.

[0047] In this embodiment, the column 330, protective net 120, support foot 230, mounting frame, first connecting plate 702 and second connecting plate 740 are all made of stainless steel.

[0048] Through this embodiment, the stainless steel structure has high strength, which can extend the service life of the protective cover.

[0049] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0050] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
