Detailed implementation manner

[0045] The present utility model provides a restoration device for constructing a characteristic diving tourism landscape by using a simple restoration technology, which is used to increase the coral reef coverage rate in the coral reef degradation area and provide a unique diving experience, aiming to encourage tourists to participate in coral protection and restoration planting, so as to promote the sustainable development of the diving tourism industry.

[0046] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0047] The device for restoring coral reef ecology and constructing a diving tourism landscape provided by an embodiment of the present utility model, as Figure 1 shown, includes: a steel frame nursery and a grid plate;

[0048] The steel frame nursery is used to be fixed on the seabed of the coral reef ecological degradation sea area;

[0049] The grid plate covers the steel frame nursery and is used for transplanting and breeding corals.

[0050] It should be noted that the steel-frame nursery, i.e., the three-dimensional steel-frame nursery, can be built or spliced by multiple steel materials (steel bars). Moreover, the steel-frame nursery is fixed on the seabed of the coral reef ecological degradation area as the framework for coral transplantation. The steel-frame nursery has feet for easy insertion and fixation under the seabed; the grid plate is covered and fixed on the steel-frame nursery as the carrier for coral transplantation and breeding;

[0051] That is to say, by fixing the steel-frame nursery on the seabed of the coral reef ecological degradation area and covering and fixing the grid plate for coral transplantation and breeding on the steel-frame nursery, a coral nursery (coral nursery platform) is built on the seabed of the coral reef ecological degradation area to repair the coral reef ecological degradation area and increase the coral reef coverage rate of the coral reef ecological degradation area. Moreover, the steel-frame coral nursery can be built or spliced by steel materials. Compared with the existing repair devices, it has the characteristics of low cost, easy design simplification, and less repair time. Of course, this steel-frame coral nursery can provide a good growth and reproduction environment for corals and can also provide a large number of transplantation sources for coral transplantation. In addition, the corals to be transplanted on the grid plate can use coral branches; among them, the coral branches can be collected from the nursery or can be picked up the coral branches broken due to natural disasters such as typhoons.

[0052] It can be seen that in the device for repairing the coral reef ecology and constructing a diving tourism landscape provided by this solution, by fixing the steel-frame nursery on the seabed of the coral reef ecological degradation area and covering the grid plate for coral transplantation and breeding on the steel-frame nursery, a steel-frame coral nursery is built on the seabed of the coral reef ecological degradation area to repair the coral reef ecological degradation area. Moreover, the steel-frame coral nursery can be built or spliced by steel materials. Compared with the existing repair devices, it has the characteristics of low cost, easy design simplification, and less repair time.

[0053] In this solution, as Figure 1 shown, the steel-frame nursery includes: a cubic steel frame 1 and two transplantation frames 2;

[0054] The cubic steel frame 1 is used to be fixed on the seabed of the coral reef ecological degradation area;

[0055] The two transplantation frames 2 are arranged obliquely downward on two opposite sides of the cubic steel frame 1;

[0056] The grid plate includes: a first grid plate 3 and two second grid plates 4;

[0057] The first grid plate 3 covers the top of the cubic steel frame 1;

[0058] The two second grid plates 4 cover the two transplantation frames 2 one by one.

[0059] Among them, as Figure 3As shown in the figure, the cubic steel frame 1 has multiple legs. By knocking on the cubic steel frame 1, the multiple legs of the cubic steel frame 1 are inserted and fixed under the seabed of the sea floor; two transplantation frames 2 are respectively arranged in an inclined downward direction, and one end of each of them is connected to two opposite sides of the cubic steel frame 1 respectively, and the other end can rest on the sea floor of the sea. In fact, the two transplantation frames 2 serve as the two side transplantation frames of the cubic steel frame 1, which are used to expand the framework for coral transplantation; the first grid plate 3 covers and is fixed on the top of the cubic steel frame 1, and two second grid plates 4 respectively cover and are fixed on the two transplantation frames 2, so that corals can be transplanted and bred on the top and both sides of the cubic steel frame 1. In this way, the capacity of transplanting corals in the steel frame coral nursery can be improved, and at the same time, it also helps to reduce the impact of resuspension of seabed sediments on the transplanted corals, ensuring the survival rate and growth rate of the transplanted corals; of course, two opposite sides of the cubic steel frame 1 can also be provided with transplantation frames inclined downward, so that corals can be transplanted and bred on the front, back, left and right sides of the cubic steel frame 1.

[0060] Specifically, as Figure 3 shown in the figure, the cubic steel frame 1 includes: two rectangular frames and four vertical rods;

[0061] The two rectangular frames are arranged parallel to each other up and down, and the four corners of one of the rectangular frames are respectively connected to the upper ends of the four vertical rods one by one, and the four corners of the other rectangular frame are respectively connected to the middle parts of the four vertical rods one by one;

[0062] The lower ends of the four vertical rods are used to be fixed on the sea floor of the coral reef ecological degradation sea area;

[0063] The two transplantation frames 2 are respectively arranged in an inclined downward direction on two opposite sides of the other rectangular frame.

[0064] Among them, as Figure 3 shown in the figure, the two rectangular frames are arranged parallel to each other up and down, and are respectively used as the upper rectangular frame and the lower rectangular frame; among them, the four corners of the upper rectangular frame are respectively connected to the upper ends of the four vertical rods one by one, and the four corners of the lower rectangular frame are respectively connected to the middle parts of the four vertical rods one by one, so as to form a cubic steel frame 1 with four legs, which is convenient for the lower part of the cubic steel frame 1 to be inserted and fixed under the sea floor of the sea bed. Of course, this also helps to improve the stability of the cubic steel frame 1; in addition, the two transplantation frames 2 are respectively arranged in an inclined downward direction on two opposite sides of the lower rectangular frame, and as described above, the lower ends of the two transplantation frames 2 will rest on the sea floor of the sea, so that the steel frame nursery can form multi-point support, which helps to improve the stability of the steel frame nursery. In addition, as Figure 1 shown in the figure, the first grid plate 3 can cover and be fixed on the upper rectangular frame and the upper ends of the four vertical rods; of course, the lower rectangular frame can also be covered and fixed with a grid plate.

[0065] Furthermore, as Figure 3As shown in the figure, the rectangular frame includes: two first long crossbars 11, two short crossbars 12 and two reinforcing diagonal bars 13;

[0066] The four vertical bars are respectively the first vertical bar 14, the second vertical bar 15, the third vertical bar 16 and the fourth vertical bar 17;

[0067] One of the two first long crossbars 11 is connected between the corresponding parts of the first vertical bar 14 and the second vertical bar 15, and the other first long crossbar 11 is connected between the corresponding parts of the third vertical bar 16 and the fourth vertical bar 17;

[0068] One of the two short crossbars 12 is connected between the corresponding parts of the first vertical bar 14 and the third vertical bar 16, and the other short crossbar 12 is connected between the corresponding parts of the second vertical bar 15 and the fourth vertical bar 17;

[0069] The two reinforcing diagonal bars 13 are respectively connected between the two first long crossbars 11.

[0070] Among them, as Figure 3 shown, for the upper rectangular frame described above, one of the two first long crossbars 11 is connected between the upper ends of the first vertical bar 14 and the second vertical bar 15, and the other first long crossbar 11 is connected between the upper ends of the third vertical bar 16 and the fourth vertical bar 17; one of the two short crossbars 12 is connected between the upper ends of the first vertical bar 14 and the third vertical bar 16, and the other short crossbar 12 is connected between the upper ends of the second vertical bar 15 and the fourth vertical bar 17;

[0071] For the lower rectangular frame described above, one of the two first long crossbars 11 is connected between the middle parts of the first vertical bar 14 and the second vertical bar 15, and the other first long crossbar 11 is connected between the middle parts of the third vertical bar 16 and the fourth vertical bar 17; one of the two short crossbars 12 is connected between the middle parts of the first vertical bar 14 and the third vertical bar 16, and the other short crossbar 12 is connected between the middle parts of the second vertical bar 15 and the fourth vertical bar 17;

[0072] In addition, as Figure 3As shown, for each rectangular frame, it also includes a reinforcing short cross bar 18; the reinforcing short cross bar 18 is connected between the middle parts of two first long cross bars 11, and two reinforcing diagonal bars 13 are respectively located on both sides of the reinforcing short cross bar 18; in addition, the first long cross bar 11, the short cross bar 12, the reinforcing diagonal bar 13 and the reinforcing short cross bar 18 are the cross beams, and the vertical bars are the columns, and the cubic steel frame 1 can be designed to be detachable. For example, any two of the above components can be connected by a screw assembly. For instance, the first long cross bar 11 can be connected between the corresponding parts of the first vertical bar 14 and the second vertical bar 15 through a screw assembly; of course, the two first long cross bars 11 are distributed relatively, and the two short cross bars 12 are also distributed relatively.

[0073] That is to say, the two first long cross bars 11 and the two short cross bars 12 enclose to form a rectangular frame, and the reinforcing short cross bar 18 and the two reinforcing diagonal bars 13 are respectively connected inside the rectangular frame, which can improve the structural strength of the rectangular frame, and the four corners of the rectangular frame are respectively connected to the corresponding parts of the four vertical bars, so as to form a long cubic steel frame, which can help to improve the structural strength and stability of the cubic steel frame 1.

[0074] Furthermore, as Figure 2 shown, the first long cross bar 11, the short cross bar 12, the first vertical bar 14, the second vertical bar 15, the third vertical bar 16 and / or the fourth vertical bar 17 are galvanized angle steels. That is to say, the cubic steel frame 1 is built or spliced by multiple galvanized angle steels; among them, the galvanized angle steel has the characteristics of low treatment cost, durability, good reliability, strong coating toughness, etc. Furthermore, it also makes the steel frame coral nursery have the characteristics of low cost, reliability and durability, and the steel frame coral nursery is detachable (two galvanized angle steels can be connected by a screw assembly), can be built on the seabed, and is also convenient for transportation, so that the construction of the steel frame coral nursery is simple and portable.

[0075] In addition, as Figure 3 shown, the length * width * height of the long cubic steel frame can be 2.0m * 1.2m * 1.5m, the specification of the galvanized angle steel can be 40 * 4, the contact part of the two galvanized angle steels is connected and fixed by drilling holes and through a screw assembly, the screws in the screw assembly can be made of 316 stainless steel, the model of the screw can be external hexagon M8 * 30, and a gasket should be padded on each inner side when the screw and the nut are tightened.

[0076] That is to say, in this scheme, the coral nursery is constructed by these simple steel materials such as galvanized angle steels. Compared with the existing repair devices, the coral nursery has low cost, is convenient for realizing a simplified design, and makes the structure of the coral nursery not so complex.

[0077] In this scheme, as Figure 3As shown, the lower ends of the first vertical rod 14, the second vertical rod 15, the third vertical rod 16 and the fourth vertical rod 17 are set to be pointed. That is, the lower ends of the four legs of the steel-frame coral nursery are set to be pointed. In this way, under the knocking of external forces, the four legs of the steel-frame coral nursery can be inserted and fixed under the seabed. In addition, the steel-frame coral nursery can be placed in a flat and fragmented area that meets the environmental conditions required for coral growth and has less coral coverage. The lower ends of the above four vertical rods are sharpened by 10 cm, and the pointed ends of the vertical rods are embedded in the rocky bottom of the flat and fragmented area by hitting with a hammer, so that the legs of the steel-frame coral nursery are firmly fixed under the seabed. In addition, to further improve the stability of the steel-frame coral nursery on the seabed, four steel rods can be knocked by a hammer to embed the four steel rods in the rocky bottom of the flat and fragmented area, and then the four steel rods are connected and fixed to the lower ends of the four vertical rods one by one (which can be fixed by tying with ropes); among them, the steel rods can be made of construction waste steel bars, with a diameter of 2 cm and a length of 20 cm.

[0078] Specifically, as Figure 3 shown, the transplanting frame 2 includes: three inclined rods 21 and two second long crossbars 22;

[0079] The three inclined rods 21 are arranged side by side in sequence, and their upper ends are respectively connected to the corresponding sides of another rectangular frame;

[0080] One of the two second long crossbars 22 is connected to the middle parts of the three inclined rods 21, and the other second long crossbar 22 is connected to the lower ends of the three inclined rods 21. Among them, as Figure 3 shown, the upper ends of the three inclined rods 21 are respectively connected to the corresponding sides (such as the front side or the rear side) of the lower rectangular frame. Of course, as described above, the lower ends of the three inclined rods 21 can rest on the seabed. That is to say, the transplanting frame 2 is designed in this way to facilitate the formation of a grid-shaped transplanting frame, which has a simple structure, is also convenient for supporting the second grid plate 4, and at the same time ensures the structural strength. In addition, the inclined rods 21 can be connected and fixed to the first long crossbar 11 on the corresponding side of the lower rectangular frame and to the second long crossbar 22 through screw assemblies.

[0081] Furthermore, as Figure 4 and Figure 5As shown, the first grid plate 3 and / or the second grid plate 4 includes a basalt grid plate. Among them, the grids of the basalt grid plate are made of basalt fibers, which have the characteristics of abundant raw materials, environmental friendliness, and sustainable development. It can avoid affecting the marine environment and also helps to reduce the cost of the first grid plate 3 and / or the second grid plate 4. The four corners of the frame of the basalt grid plate can be tied and fixed to the top of the cubic steel frame 1 or the transplantation frame 2 through nylon ropes. That is to say, the selection of the basalt grid plate for the first grid plate 3 and / or the second grid plate 4 has the characteristics of environmental protection and low cost. In addition, coral branches can be fixed on the first grid plate 3 and / or the second grid plate 4 through cable ties.

[0082] Furthermore, as Figure 7 shown, the number of steel frame nurseries is multiple, and multiple steel frame nurseries are used to be fixedly arranged side by side in sequence on the seabed of the coral reef ecological degradation area;

[0083] The number of grid plates is multiple, and multiple grid plates cover multiple steel frame nurseries one by one.

[0084] Among them, multiple steel frame nurseries are fixedly arranged side by side adjacent to each other in sequence on the seabed of the coral reef ecological degradation area, that is, multiple steel frame nurseries are serially fixed in an orderly manner at the predetermined positions on the seabed according to the design. Multiple grid plates cover multiple steel frame nurseries one by one. In this way, multiple adjacent and side-by-side steel frame coral nurseries can be formed on the seabed of the coral reef ecological degradation area, which is convenient for forming a landscape where corals are adjacent and side by side, and a characteristic underwater landscape can be constructed, thus facilitating the provision of a unique diving experience for divers. In addition, after multiple steel frame nurseries are arranged side by side adjacent to each other, while each steel frame nursery is fixed to the seabed, two adjacent steel frame nurseries can also be tied and fixed through cables to enhance the stability of multiple adjacent and side-by-side steel frame nurseries. Of course, as Figure 7 shown, the direction in which multiple steel frame nurseries are arranged side by side is perpendicular to the direction opposite to the two transplantation frames 2 of the steel frame nursery, avoiding side-by-side interference.

[0085] In this solution, as Figure 7 shown, the device provided by the embodiment of the present utility model for restoring the coral reef ecosystem and constructing a diving tourism landscape further includes multiple different word signs 5;

[0086] Multiple different word signs 5 are arranged on multiple steel frame nurseries one by one, so that multiple different word signs 5 are displayed on multiple steel frame nurseries, which is convenient for constructing a more characteristic underwater landscape, thus facilitating the provision of a more unique diving experience for divers. Of course, multiple different word signs 5 have different special meanings, and word signs such as Figure 7 shown can be adopted, such as using "I", "LOVE", and "China" respectively. In addition, as Figure 6As shown in the figure, the word sign 5 is a three-dimensional word sign, which can be welded by steel bars. Moreover, the word sign 5 can be set on the steel-frame nursery through the bracket 7, and the word sign 5 also facilitates landscaping by transplanting and breeding corals. One end of the bracket 7 is welded to the word sign 5, and the other end can be fixed to the first long crossbar 11 through a screw assembly. In addition, as Figure 6 shown, a support frame 6 is also provided on the steel-frame nursery for transplanting and breeding corals. In addition, suitable branched corals can be selected and fixed to the first grid plate 3, the second grid plate 4, the word sign 5, and the support frame 6 respectively through cable ties, which is convenient for forming a characteristic diving landscape.

[0087] That is to say, this solution provides a device that combines coral restoration and diving landscape, that is, a plurality of word signs 5 with different special meanings are respectively set on a plurality of serially connected steel-frame coral nurseries, which is convenient for forming a diving landscape with unique significance, so as to provide a unique diving experience for divers. Of course, building such a diving landscape has a relatively low cost and can also make a certain contribution to the sustainable development of the diving tourism industry.

[0088] It can be seen that this solution provides a device for constructing a characteristic diving tourism landscape using simple restoration techniques, which can help the tourism industry actively participate in the restoration and protection of coral reef ecological landscapes, and can provide a unique diving tourism experience to attract more tourists.

[0089] The installation process of this device:

[0090] 1. Screening of the placement location: After splicing the detachable steel-frame nursery (6 short crossbars, 4 reinforcing diagonal bars, 4 long crossbars, and 4 vertical bars), basalt grid plates, and three-dimensional steel-letter signs (i.e., word signs), generally select a sea area with a flat terrain and fragmented bottom sediment as the placement sea area;

[0091] 2. Use a hammer to embed all the feet (vertical bars) of this device into the fragmented reef flat. The feet are inserted into the base about 0.10 m, and use cables to splice multiple detachable nursery platforms to increase the stability of multiple detachable nursery platforms. After the main frame is fixed, connect the inclined transplant panels (i.e., transplant frames) on both sides and connect the three-dimensional letter or word sign at the top and fix it with screws.

[0092] Coral transplantation process: Use ropes to cover the spliced cube steel frame and the inclined transplant panels with basalt grid plates, select suitable branched corals, and transplant them on the basalt grid plates and three-dimensional letter signs (i.e., word signs) using cable ties, and construct a diving landscape.

[0093] In summary, the present utility model discloses a device that combines coral restoration and diving landscape, aiming to establish coral nurseries for restoring ecologically degraded areas of coral reefs and simultaneously constructing a characteristic diving tourism landscape. Among them, fragmented areas suitable for coral growth are selected and fixed into a cubic steel frame using galvanized angle steel and screws, and at the same time, a basalt grid plate is covered to construct a coral nursery. A three-dimensional letter sign (i.e., a word sign) welded by steel bars can be connected to the coral nursery. After arranging and designing multiple coral nurseries, an undersea landscape is constructed. The coral nursery constructed by this device can ensure the survival rate and growth rate of transplanted corals, provide seedlings for field coral restoration, and design and form a characteristic diving tourism landscape, providing a unique diving experience for tourists and also helping to enhance the awareness of coral protection. In addition, the device has relatively low restoration and landscaping costs and can contribute to the sustainable development of the diving tourism industry.
