Description
Technical Field
The invention 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 corals and calcium carbonate skeletons thereof serving as main bodies and calcareous organisms in a reef area, and an ecological system of the coral reef is known as a tropical rainforest in the ocean and has extremely rich biodiversity. The coral reef is taken as a typical offshore ecosystem, has the ecological functions of wave prevention and bank protection and environmental regulation, and provides important strategic resource guarantee in the aspects of marine fishery, tourism, biodiversity protection, new drug development and the like. However, coral reefs worldwide die and deteriorate on a large scale due to factors such as ocean over-exploitation and utilization, continous input of terrestrial pollutants, and seawater warming and acidification caused by global climate change. In the past decades, the coverage rate of the south China sea coral is sharply reduced by 80%. The bottom trawl is a destructive fishing mode, which not only drains benthonic organisms on one net, but also seriously damages the seabed, thus becoming the largest killer of the marine benthonic ecosystem. 97-99% of deep sea corals in Florida and New Zealand, USA, are destroyed by the bottom trawl. At present, the catching mode of the bottom trawl is not effectively limited, so that the destructive influence on the coral reef is not ignored.
In order to avoid adverse effects 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 commonly used repairing method is coral limb-breaking transplantation, that is, coral limb-breaking is transplanted directly on the damaged reef plate or on the coral repairing device, and then the repairing device is placed at the bottom of the sea area to be repaired. However, the existing devices for coral ecological restoration mainly consider factors such as growth and reproduction, hydrology and geology of the coral, and little manual disturbance such as bottom trawl fishing is involved. The artificial disturbance often has large destructive power, influences the normal growth of the coral, reduces the survival rate of the coral, and causes the coral repairing effect to be not obvious.
The invention patent application with the application number of CN201710447675.4 discloses a submarine coral culture base, which comprises a truncated cone-shaped base body, positioning claws, a stud and a positioning frame positioned below the base. The invention patent application provides a submarine coral culture plate, which allows a user to adjust the transverse position of an adjusting plate and the longitudinal position of a positioning frame according to the topography of the seabed, so that the user can stably place the seabed. However, the above-mentioned submarine coral culture plate also has many drawbacks: firstly, the adjusting plate and the positioning frame of the submarine coral culture seat are both arranged below the seat body, so that the seat body for transplanting the coral is suspended, and the seat body is easy to be dragged or dragged away by a fishing net when encountering a trawl. Secondly, whether the submarine coral culture medium can be stably placed on the seabed depends on whether the placed seabed is flat or not. However, marine hydrological and geological environments are complex and variable, and it is difficult to create stable and flat seafloor conditions. The supporting structure (the adjusting plate and the positioning frame) of the seabed coral culture seat provided by the patent application of the invention needs to be preset, is lack of adaptability, is easy to incline when being thrown on the seabed through the hoisting equipment, is easier to be dragged by a fishing net, and is even overturned by sea wave and ocean current. Thirdly, the stud and the positioning claw of the submarine coral culture seat provided by the invention patent application are exposed out of the seat body, so that the dragging risk is increased. Finally, the submarine coral culture medium and the coral transplanting surface are both in a truncated cone shape, and the design can cause the trawl to shed the coral.
The utility model patent application for application number CN202121615376.5 discloses a prevent coral nursery frame of fishing net, it includes seedbed, reinforcement muscle, blocks net frame and pillar, and it prevents the fishing net through blocking the net frame and drags the seedbed, consolidates the seedbed through strengthening rib and pillar, confronts the fishing net and drags the effect. Although in an ideal situation this structure does prevent the net from dragging, it is difficult to achieve in practical applications: firstly, the seedbed needs to be fixed on the complicated and changeable seabed through the support columns, the operation difficulty is high, and the cost is high. Secondly, the coral nursery frame forms rigid confrontation to the dragging of the fishing net, so that the damage or falling of the fishing net is easy to occur, or the nursery frame is pulled up in a full disk manner, and the situation that the fishing net and the nursery frame are damaged at the same time is possible to occur. Finally, the coral nursery frame with the anti-trawl net also needs to be provided with a support column in advance, and is lack of self-adaptive support, so that the whole nursery frame is easy to incline.

Accordingly, the above terms should not be construed as limiting the present invention.
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 invention is illustrated, wherein the coral ecological restoration device includes an ecological restoration body 10 and a plurality of support members 20, wherein the ecological restoration body 10 forms a top end 11, an outer periphery 12, a plurality of guide support ridges 13, a plurality of first attachment surfaces 101, and a plurality of second attachment surfaces 102, wherein the guide support ridges 13 extend obliquely downward from the top end 11 to the outer periphery 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 periphery 12, respectively, the support members 20 are provided at the guide support ridges 13, respectively, wherein the support members 20 are provided for providing support to the ecological restoration body 10. It is understood that the first attachment surface 101 and the second attachment surface 102 of the ecological restoration body 10 of the coral ecological restoration device according to the present invention are provided for attachment and growth of coral. Preferably, 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 invention are respectively formed between every adjacent two of the guide support ridges 13. Preferably, the guide support ridges 13 continuously extend downward from the top ends 11 to the outer peripheral edges 12, respectively.
It should be noted that the first attaching surface 101 and the second attaching surface 102 of the ecological restoration main body 10 of the coral ecological restoration device are respectively formed between every two adjacent guiding support ridges 13, the guiding support ridges 13 are respectively extended from the top end 11 to the outer periphery 12 in a downward inclination manner, the first attaching surface 101 and the second attaching surface 102 are respectively extended from the guiding support ridges 13 to the outer periphery 12 in a downward inclination manner, so that the first attaching surface 101 and the second attaching surface 102 of the ecological restoration main body 10 are respectively recessed between every two adjacent guiding support ridges 13, and the guiding support ridges 13 are always located at a higher height than the first attaching surface 101 and the second attaching surface 102 along the extending direction thereof. Accordingly, when the bottom trawl passes through the position of the sea bottom where the coral ecological restoration device of the present invention is located, the guide support ridges 13 of the ecological restoration main body 10 of the coral ecological restoration device of the present invention can guide the fishing net to move upward therealong and make the fishing net slide along the guide support ridges 13. In addition, the first attachment surface 101 and the second attachment surface 102 of the ecological restoration main body 10 of the coral ecological restoration device of the present invention are recessed between every adjacent two guide support ridges 13, respectively, so that coral attached to the first attachment surface 101 and the second attachment surface 102 of the ecological restoration main body 10 is scraped to be detached from the first attachment surface 101 and the second attachment surface 102 when a fishing net is supported by the guide support ridges 13 and prevented from sliding along the guide support ridges 13. Further, the guiding support ridge 13 is located at a position higher than the positions of the first attachment surface 101 and the second attachment surface 102 along the extending direction of the guiding support ridge 13, the orthographic projection length of the guiding support ridge 13 is greater than the orthographic projection length of the first attachment surface 101 and the second attachment surface 102, the group of support assemblies 20 comprises at least three support assemblies 20, so as to ensure that the bottom trawl passes through the coral ecological restoration device of the invention as far as possible, and the first contact position of the coral ecological restoration device of the invention is always the support assembly 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 invention 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 are formed on the attachment side 103, and the support side 104 is adapted to be supported on the ground (or the sea bottom). Further, the attaching side 103 is recessed inward from the outer periphery 12 of the ecological restoration main body 10, so that when the supporting side 104 of the ecological restoration main body 10 of the coral ecological restoration device of the present invention is supported on the sea bottom, it is ensured as much as possible that the outer periphery 12 of the ecological restoration main body 10 can be in close contact with the sea bottom, and the probability that the outer periphery 12 of the ecological restoration main body 10 is suspended and a fishing net is hung when a fishing net passes through the ecological restoration main body 10 of the coral ecological restoration device is reduced greatly, and the fishing net is guided to slide along the guiding and supporting ridge 13 as much as possible. Especially when the coral ecological restoration device of the present invention is placed on uneven sea floors, if the supporting side 104 of the ecological restoration body 10 of the coral ecological restoration device of the present invention is flat and it is supported on the uneven sea floors, it is likely to cause a part or all of the outer periphery 12 of the ecological restoration body 10 of the coral ecological restoration device of the present invention to hang over, increasing the risk of fishing net trawling. However, when the supporting side 104 of the ecological restoration body 10 of the coral ecological restoration device of the present invention is depressed inward, even if it is supported on a raised sea bottom, it is possible to allow the outer periphery 12 of the ecological restoration body 10 of the coral ecological restoration device of the present invention to be supported on the sea bottom.
As shown in fig. 1A to 5 of the drawings, the ecological restoration main body 10 of the coral ecological restoration device according to the embodiment of the present invention has a rim portion 15 and an extension portion 16 extending from the rim portion 15, wherein the rim portion 15 forms the outer peripheral edge 12 of the ecological restoration main body 10, and the extension portion 16 forms the top end 11 of the ecological restoration main body 10. Further, the edge 15 of the ecological restoration main body 10 of the coral ecological restoration device of the present invention is formed with an arc-shaped projection 151, and the arc-shaped projection 151 extends upward from the outer periphery 12 of the ecological restoration main body 10. Accordingly, the arc-shaped protrusion 151 can further ensure that the outer circumference 12 of the ecological restoration body 10 is supported on the seabed, reduce the risk of dragging a fishing net and guide 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 guiding support ridge 13 of the ecological restoration main body 10 of the coral ecological restoration device according to the embodiment of the present invention forms a sliding groove 1301 and a holding groove 1302, the support assembly 20 includes a support member 21, a sliding member 22, a restoring member 23 and a holding member 24, wherein the sliding member 22 is disposed on the inner wall 210 of the support member 21, and the sliding member 22 is slidably received in the sliding groove 1301; the retaining member 24 extends longitudinally outward from the slider 22, and the retaining member 24 engages the retaining slot 1302; the restoring member 23 has one end fixed to the inner sidewall 1303 of the sliding groove 1301 and the other end fixed to the sliding member 22, and when the retaining member 24 is engaged in the retaining groove 1302, the restoring member 23 is held in a compressed state, wherein the retaining member 24 is formed by solidifying a water-soluble material, wherein the ecological restoration body 10 is formed with at least one water inlet hole 105, wherein the water inlet hole 105 is in communication with the retaining groove 1302 to allow seawater to flow to the retaining groove 1302. Preferably, the sliding groove 1301 extends from the outer periphery 12 of the ecological restoration body 10. Accordingly, as shown in fig. 2 to 5 and 11 of the drawings, the supporting member 20 of the coral ecological restoration device according to the embodiment of the present invention has a first working position and a second working position, wherein when the supporting member 20 is in the first working position, the supporting member 21 of the supporting member 20 is located between the top end 11 and the outer periphery 12, and at this time, the supporting member 20 of the coral ecological restoration device according to the embodiment of the present invention is not placed in the sea; when the support member 20 is at the second working position, the support member 21 of the support member 20 slides outward to a proper distance beyond the outer periphery 12 to be supported on the sea bottom, and at this time, the support member 20 of the coral ecological restoration apparatus according to the embodiment of the present invention is put into the sea and sunk to the sea bottom. Therefore, in order to ensure the stable support of the coral ecological restoration device of the present invention, the melting time of the retaining member 24 can be preset so that the retaining member 24 can completely melt and release the restoring member 23 after the coral ecological restoration device of the present invention sinks to the sea bottom, thereby ensuring that the sliding distance of the supporting member 21 on the restoring member 23 is determined by the weight of the coral ecological restoration device of the present invention, the length and elastic coefficient of the restoring member 23, and the length and arrangement position of the sliding groove 1301, and not causing the supporting member 21 (or the supporting member 20) to provide rigid support for the coral ecological restoration device of the present invention itself when the supporting member 21 (or the supporting member 20) is completely ejected from the sea bottom and under the weight of the coral ecological restoration device of the present invention. Therefore, as shown in fig. 4 and 5 of the drawings, when the coral ecological restoration device of the present invention is placed on the sea bottom, seawater flows to the holding tank 1302 along the predetermined water inlet holes 105, so that the holding members 24 are completely melted and the restoring members 23 are released to push the support members 21 to slide outward along the slide grooves 1301 and to support the support members 21 on the sea bottom. Accordingly, when the coral ecological restoration device of the present invention is placed on a rugged sea floor, the support members 21 of the support assembly 20 can further provide supplementary support to the coral ecological restoration device of the present invention to ensure that the coral ecological restoration device of the present invention can be stably supported on the sea floor. Therefore, the supporting component 20 of the coral ecological restoration device has the function of preventing the coral ecological restoration device from being seriously inclined or swayed under the disturbance of water flow because part of the structure of the coral ecological restoration device is not strongly supported. In addition, the coral ecological restoration device is easy to hang in a net when the coral ecological restoration device is seriously inclined or swayed. Preferably, the return member 23 is a return spring.
It is noted that the length of the sliding groove 1301, the extension of the restoring member 23 and the length of the supporting member 21 are preset to ensure that when the holding member 24 is completely melted, the supporting member 21 (possibly more than one) of the supporting assembly 20 can slide outward to a proper distance beyond the outer periphery 12 and the coral ecological restoration device of the present invention is stably supported on the sea bottom. It is understood that the proper distance that the supporting member 21 of the supporting assembly 20 can slide outward beyond the outer periphery 12 is determined by the weight of the coral ecological restoration device of the present invention, the length and elastic modulus of the restoring member 23, and the length and arrangement position of the sliding groove 1301. In addition, the distance that the supporting member 21 of each supporting component 20 of the coral ecological restoration device can slide outward beyond the outer periphery 12 is also related to the flatness and hardness of the sea bottom. When the gravity applied to the supporting member 21 of the supporting member 20 by the coral ecological restoration device of the present invention 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 bottom. Therefore, the supporting component 20 of the coral ecological restoration device has a certain self-adaptive adjustment capability.
As shown in fig. 1A to fig. 6 of the drawings, further, the supporting member 21 of the supporting assembly 20 of the coral ecological restoration device according to the embodiment of the present invention 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 device of the present invention is placed on the sea bottom, seawater flows to the holding groove 1302 along the predetermined water inlet holes 105, melts the holding member 24 and releases the restoring member 23 to push the support member 21 to slide outwardly along the slide groove 1301, so that the support member 21 can function to guide the fishing net to slide along the support member 21 while being supported on the sea bottom.
