Description
Technical Field
The utility model relates to the field of marine ecological restoration, in particular to a coral ecological restoration device with a self-adaptive trawl prevention function.
Background
The coral reef is a rock structure formed by stacking hermatypic coral and calcium carbonate bones thereof serving as main bodies and calcareous organisms in a reef area, and the ecological system of the coral reef is known as a tropical rain forest in the ocean, so that the coral reef has extremely rich biodiversity. The coral reef is used as a typical offshore ecological system near the shore, has the ecological functions of wave prevention, shore protection and environmental regulation, and provides important strategic resource guarantee in the aspects of marine fishery, travel industry, biodiversity protection, new medicine development and the like. However, coral reefs worldwide die and degenerate on a large scale due to factors such as over-development and utilization of the ocean, continuous input of land-based pollutants, rising temperature and acidification of sea water caused by global climate change, and the like. Over the past decades, the coverage rate of the coral in the south China sea is sharply reduced by 80 percent. The trawl is a destructive fishing mode, not only can the benthonic organisms be completely caught, but also the seabed is seriously damaged, and the trawl becomes the largest killer of the benthonic ecosystem. The deep sea coral of florida and New Zealand 97-99% in the United states is destroyed by the bottom trawl. At present, the trawl fishing mode is not limited effectively, so that the destructive influence on the coral reef is not ignored.
In order to avoid the adverse effect of the damage of the offshore coral reef on the marine ecological environment, artificial measures are necessary to repair the degraded or damaged coral reef. The common repair method is a coral amputation transplanting method, namely, the coral amputation is directly transplanted on a damaged reef disk or is transplanted on a coral repair device, and then the repair device is put on the bottom of a sea area to be repaired. However, the existing device for ecological restoration of corals mainly considers factors such as growth and propagation of corals, hydrology, geology and the like, and involves little artificial disturbance such as trawl fishing. The artificial disturbance often has large destructive power, influences the normal growth of corals, reduces the survival rate of the corals, and causes insignificant repair effects of the corals.
The utility model patent application with the application number of CN201710447675.4 discloses a submarine coral culture seat, which comprises a seat body in the shape of a circular table, a positioning claw, a stud and a positioning frame positioned below the seat body. The seafloor coral culture medium provided by the patent application allows a user to adjust the transverse position of the adjusting plate and the longitudinal position of the positioning frame according to the seafloor topography so that the seafloor coral culture medium can be stably placed on the seafloor. However, the above-mentioned seafloor coral culture trays also have a number of drawbacks: firstly, the adjusting plate and the locating rack of the seafloor coral culture seat are arranged below the seat body, so that the seat body for transplanting coral is suspended, and the seat body is easy to be dragged over or dragged away by a fishing net when encountering the trawl. Second, whether the seafloor coral culture section can be stably placed on the sea floor depends on whether the placed sea floor is flat or not. However, marine hydrologic and geological environments are complex and variable, and it is difficult to create stable and flat seabed conditions. The support structure (the adjusting plate and the positioning frame) of the seafloor coral culture seat provided by the patent application needs to be preset, and the support structure lacks of self-adaptability, and is easy to incline, more easy to be towed by a fishing net and even to be overturned by sea wave and ocean current when being thrown on the seafloor through lifting equipment. And the studs and the positioning claws of the submarine coral culture seat provided by the patent application are exposed out of the seat body, so that the risk of dragging is increased. Finally, both the submarine coral culture seat and the coral transplanting surface are in a truncated cone shape, and the design can lead the trawl to drop off the coral.
The patent application of the utility model with the application number of CN202121615376.5 discloses a coral nursery frame for preventing a fishing net, which comprises a seedbed, reinforcing ribs, a blocking net frame and supporting columns, wherein the blocking net frame is used for preventing the fishing net from dragging the seedbed, and the reinforcing ribs and the supporting columns are used for reinforcing the seedbed to resist the dragging effect of the fishing net. Although this structure does prevent the fishing net from being towed in an ideal situation, it is difficult to achieve in practical applications: firstly, the seedbed needs to be fixed on the seabed which is complex and changeable through the support column, so that the operation difficulty is high and the cost is high. Secondly, the coral nursery frame drags the fishing net to form rigid countermeasure, which is easy to damage or drop the fishing net or the nursery frame is pulled up by a whole disk, and the condition that the fishing net and the nursery frame are damaged at the same time is also likely to occur. Finally, the coral nursery frame of the trawl-preventing net also needs to be provided with a support in advance, and the whole nursery frame is easy to incline due to the lack of self-adaptive support.

And when the fishing net passes through, the fishing net is supported by the guide supporting ridges, so that the fishing net can not contact with the coral transplanted on the fishing net, and the coral is prevented from being dragged by the fishing net to fall off.
Another advantage of the present utility model is to provide a coral ecological restoration device, in which the self-adaptive support assembly can be automatically adjusted according to the sea floor topography, so as to prevent the outer periphery of the main body of the coral ecological restoration device from being suspended on the sea floor, avoid trawl passing through, and reduce the risk of trawl being towed by fishing net. In other words, the user does not need to preset the supporting position of the supporting component, and does not need to submerge the seabed to set the supporting component to play a role.
The utility model also has the advantage of providing the coral ecological restoration device which has simple structure, low price and easy manufacture and use.

Accordingly, the above terms should not be construed as limiting the present utility model.
Referring to fig. 1A to 11 of the drawings of the present specification, a coral ecological restoration device according to an embodiment of the present utility model is illustrated, wherein the coral ecological restoration device includes an ecological restoration body 10 and a set of support members 20, wherein the ecological restoration body 10 forms a top end 11, an outer peripheral edge 12, a set of guide support ridges 13, a set of first attachment surfaces 101, and a set of second attachment surfaces 102, wherein the guide support ridges 13 extend obliquely downward from the top end 11 to the outer peripheral edge 12, respectively, the first attachment surfaces 101 and the second attachment surfaces 102 extend obliquely downward from the guide support ridges 13 to the outer peripheral edge 12, respectively, the support members 20 are disposed at the guide support ridges 13, respectively, wherein the support members 20 are disposed to provide support for the ecological restoration body 10. It will be appreciated that the first attachment surface 101 and the second attachment surface 102 of the ecological restoration body 10 of the coral ecological restoration device of the present utility model are configured for attachment and growth of corals. Preferably, the first and second attaching surfaces 101 and 102 of the ecological restoration body 10 of the coral ecological restoration device of the present utility model are formed between each adjacent two of the guide-support ridges 13, respectively. Preferably, the guide support ridges 13 extend continuously downwards from the top end 11 to the outer periphery 12, respectively.
It should be noted that, in the ecological restoration device of the present utility model, the first attachment surface 101 and the second attachment surface 102 of the ecological restoration body 10 are respectively formed between every two adjacent guide supporting ridges 13, the guide supporting ridges 13 respectively extend downward from the top end 11 to the outer periphery 12, the first attachment surface 101 and the second attachment surface 102 respectively extend downward from the guide supporting ridges 13 to the outer periphery 12, so that the first attachment surface 101 and the second attachment surface 102 of the ecological restoration body 10 are respectively recessed between every two adjacent guide supporting ridges 13, and the height of the guide supporting ridges 13 along the extending direction thereof is always higher than the height of the first attachment surface 101 and the second attachment surface 102. Accordingly, the guide support ridge 13 of the ecological restoration body 10 of the coral ecological restoration device of the present utility model can guide the fishing net to move upward therealong and slide the fishing net therealong while the bottom trawl passes the seabed location where the coral ecological restoration device of the present utility model is located. In addition, the first and second attachment surfaces 101 and 102 of the ecological restoration body 10 of the coral ecological restoration device of the present utility model are respectively recessed between every adjacent two guide and support ridges 13, so that when a fishing net is supported by the guide and support ridges 13 and the fishing net is prevented from sliding along the guide and support ridges 13, coral attached to the first and second attachment surfaces 101 and 102 of the ecological restoration body 10 is scraped so that it falls off from the first and second attachment surfaces 101 and 102. Further, the height of the guide supporting ridge 13 along the extending direction thereof is always higher than the height of the first attaching surface 101 and the second attaching surface 102, the orthographic projection length of the guide supporting ridge 13 is longer than the orthographic projection length of the first attaching surface 101 and the second attaching surface 102, and the group of supporting components 20 comprises at least three supporting components 20, so as to ensure that the bottom trawl passes through the coral ecological restoration device of the present utility model as much as possible, and the part of the coral ecological restoration device of the present utility model that is first contacted is always the supporting component 20.
As shown in fig. 1A and 1B of the drawings, the ecological restoration body 10 of the coral ecological restoration device according to the embodiment of the present utility model has an attachment side 103 and a support side 104, wherein the guide support ridge 13, the first attachment surface 101, and the second attachment surface 102 form the attachment side 103, and the support side 104 is adapted to be supported on the ground (or the sea floor). Further, the attaching side 103 is recessed inward from the outer periphery 12 of the ecological restoration body 10, so that when the supporting side 104 of the ecological restoration body 10 of the coral ecological restoration device of the present utility model is supported on the sea floor, the outer periphery 12 of the ecological restoration body 10 can be ensured to be in close contact with the sea floor as much as possible, the probability that the outer periphery 12 of the ecological restoration body 10 hangs in the air and the fishing net hangs on the net is greatly reduced and the fishing net is guided to slide along the guiding supporting ridge 13 as much as possible when the fishing net passes through the ecological restoration body 10 of the coral ecological restoration device of the present utility model. Especially when the coral ecological restoration device of the present utility model is placed on a rough sea floor, if the supporting side 104 of the ecological restoration body 10 of the coral ecological restoration device of the present utility model is a plane and it is supported on a raised sea floor, it is likely that part or all of the outer periphery 12 of the ecological restoration body 10 of the coral ecological restoration device of the present utility model is suspended, increasing the risk of trawling a fishing net. However, when the supporting side 104 of the ecological restoration body 10 of the coral ecological restoration device of the present utility model is recessed inward, it is possible to allow the outer peripheral edge 12 of the ecological restoration body 10 of the coral ecological restoration device of the present utility model to be supported by the sea floor even if it is supported on the raised sea floor.
As shown in fig. 1A to 5 of the drawings, the ecological restoration body 10 of the coral ecological restoration device according to the embodiment of the present utility model has an edge portion 15 and an extension portion 16 extending from the edge portion 15, wherein the edge portion 15 forms the outer periphery 12 of the ecological restoration body 10, and the extension portion 16 forms the top end 11 of the ecological restoration body 10. Further, the edge portion 15 of the ecological restoration body 10 of the coral ecological restoration device of the present utility model forms an arc-shaped protrusion 151, and the arc-shaped protrusion 151 extends upward from the outer circumference 12 of the ecological restoration body 10. Accordingly, the arcuate projections 151 may further ensure that the outer peripheral edges 12 of the ecological restoration body 10 are supported on the sea floor, reducing the risk of drag of the fishing net and guiding the fishing net to slide along the surface of the attachment side 103 of the ecological restoration body 10.
As shown in fig. 1A to 6 of the drawings, the guide support ridge 13 of the ecological restoration body 10 of the coral ecological restoration device according to the embodiment of the present utility model forms a sliding groove 1301 and a holding groove 1302, the support assembly 20 includes a support 21, a slider 22, a restoring member 23, and a holding member 24, wherein the slider 22 is disposed at an inner wall 210 of the support 21, and the slider 22 is slidably received in the sliding groove 1301; the retainer 24 extends longitudinally outward from the slider 22, and the retainer 24 engages the retention slot 1302; one end of the restoring member 23 is fixed to the inner sidewall 1303 of the sliding groove 1301 and the other end is fixed to the sliding member 22, and when the holding member 24 is engaged in the holding groove 1302, the restoring member 23 is held in a compressed state, wherein the holding member 24 is formed by solidifying a water-soluble material, wherein the ecological restoration body 10 forms at least one water inlet hole 105, wherein the water inlet hole 105 communicates with the holding groove 1302 to enable seawater to flow to the holding groove 1302. Preferably, the sliding groove 1301 extends from the outer circumference 12 of the ecological restoration body 10. Accordingly, as shown in fig. 2 to 5 and 11 of the drawings, the supporting component 20 of the coral ecological restoration device according to the embodiment of the present utility model has a first working position and a second working position, wherein when the supporting component 20 is in the first working position, the supporting component 21 of the supporting component 20 is located between the top end 11 and the outer periphery 12, and at this time, the supporting component 20 of the coral ecological restoration device according to the embodiment of the present utility model is not put into the sea; when the support assembly 20 is in the second working position, the support members 21 of the support assembly 20 are slid outwardly a suitable distance beyond the outer periphery 12 to be supported on the sea floor, at which point the support assembly 20 of the coral ecological restoration apparatus according to embodiments of the present utility model is placed into the sea and submerged into the sea floor. Therefore, in order to ensure stable support of the coral ecological restoration device of the present utility model, the melting time of the retainer 24 may be preset so that the retainer 24 can completely melt and release the restoring member 23 after the coral ecological restoration device of the present utility model is sunk to the sea floor, thereby ensuring that the sliding distance of the supporting member 21 at the restoring member 23 is determined by the gravity of the coral ecological restoration device of the present utility model, the length and elastic coefficient of the restoring member 23, the length and the setting position of the sliding groove 1301, so that the supporting member 21 (or the supporting member 20) itself provides rigid support for the coral ecological restoration device of the present utility model without completely popping up upon being put into the sea floor and under the gravity of the coral ecological restoration device of the present utility model. Thus, as shown in fig. 4 and 5 of the drawings, after the coral ecological restoration device of the present utility model is placed on the ocean floor, seawater flows to the holding groove 1302 along the preset water inlet hole 105, so that the holding member 24 is completely melted and the restoring member 23 is released to push the supporting member 21 to slide outward along the sliding groove 1301 and the supporting member 21 is supported on the ocean floor. Accordingly, when the coral ecological means of the present utility model is placed on a rugged seabed, the support members 21 of the support assembly 20 may further provide supplementary support for the coral ecological means of the present utility model to ensure that the coral ecological means of the present utility model can be stably supported on the seabed. Accordingly, the supporting member 20 of the coral ecological means of the present utility model has a function of preventing a part of the structure of the coral ecological means of the present utility model from being severely inclined or swaying under the disturbance of water flow without being strongly supported. In addition, the coral ecological restoration device is easy to hang when being severely inclined or swayed. Preferably, the return member 23 is a return spring.
Notably, the length of the chute 1301, the extended length of the return member 23 and the length of the support member 21 are all pre-set to ensure that when the retaining member 24 is completely melted, the support member 21 (and possibly more than one) of the support assembly 20 is able to slide outwardly a suitable distance beyond the outer periphery 12 and to allow the coral ecological restoration apparatus of the present utility model to be stably supported on the seafloor. It will be appreciated that the proper distance that the support 21 of the support assembly 20 can slide outwardly beyond the outer periphery 12 is determined by the weight of the coral ecological restoration device of the present utility model, the length and elastic modulus of the restoring member 23, the length and placement of the chute 1301. In addition, the distance that the support 21 of each support assembly 20 of the coral ecological restoration device of the present utility model can slide outward beyond the outer periphery 12 is also related to the flatness and hardness of the sea floor. When the gravity of the supporting member 21 applied to the supporting member 20 by the coral ecological restoration device of the present utility model is balanced with the elastic force provided by the restoring member 23, the supporting member 21 of the supporting member 20 is stably supported on the sea floor. Thus, the support assembly 20 of the coral ecological restoration device of the present utility model has a certain adaptive adjustment capability.
As shown in fig. 1A to 6 of the drawings, further, the supporting member 21 of the supporting component 20 of the coral ecological restoration device according to the embodiment of the present utility model includes two supporting pieces 211, wherein the supporting pieces 211 are configured to be attached to the first attaching surface 101 and the second attaching surface 102 of the ecological restoration body 10. Accordingly, when the coral ecological restoration apparatus of the present utility model is placed on the seabed, seawater flows to the holding groove 1302 along the predetermined water inlet 105, melts the holding piece 24 and releases the restoring piece 23 to push the supporting piece 21 to slide outward along the sliding groove 1301, so that the supporting piece 21 can play a role of guiding the fishing net to slide along the supporting piece 21 when the supporting piece 21 is supported on the seabed.
