Description

Technical Field

[0001] The invention belongs to the field of coral reef ecological restoration, in particular to an anti-trawling underwater coral ecological restoration device. Background Art

[0002] In recent decades, the rapid development of coastal socio-economic development, the continuous expansion of human land and the over-exploitation of marine resources have led to global warming, ocean acidification, and sea level rise. Human overfishing, destructive fishing, and pollutant emissions have become environmental issues that affect the world. These continuous, slow, low-level disturbances have posed a serious threat to coral reef ecosystems, causing the coral reef area to shrink and even disappear in some areas.

[0003] Fishermen often use trawling when catching fish, which not only causes great damage to the fish resources themselves, but also causes great damage to the marine ecological environment on which fish depend for survival.

[0004] At present, the restoration of underwater coral ecology mainly adopts coral transplantation and construction of artificial reefs. However, when cultivating corals, corals exposed to the seabed may be caught by trawl nets, which will affect the growth of corals. Therefore, it is necessary to propose an anti-trawl underwater coral ecology restoration device. Summary of the invention

[0005] In order to solve the problem that the above-mentioned trawling may affect the growth of corals, the purpose of the present invention is to propose an anti-trawling underwater coral ecological restoration device, which achieves the anti-trawling effect of the entire device through the locking effect of the arc shovel and seaweed on the entire device, and the buffering effect of the non-Newtonian fluid layer on the force exerted on the device. At the same time, the corals are protected by the outer shell, and the use of halogen lamps allows the photosynthesis of the corals to be more complete, providing a more suitable growth environment for the corals.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an anti-trawling underwater coral ecological restoration device, comprising an outer shell, an upper base detachably connected to the bottom of the outer shell, a plurality of pistons are provided at the bottom of the upper base, a lower base is detachably connected to the bottom of the piston, a locking assembly for locking the underwater coral ecological restoration device is provided at the bottom of the lower base, a seaweed cultivation net is provided along the circumference of the bottom of the lower base, a plurality of seaweeds are cultivated on the surface of the seaweed cultivation net, a non-Newtonian fluid layer is provided on the outer wall of the outer shell, and a plurality of buffer assemblies for buffering ocean currents and a plurality of cultivation assemblies for coral cultivation are equidistantly and staggeredly provided on the two inner side walls of the outer shell.

[0007] The principle of the basic solution is: the staff fix the coral larvae on the cultivation components inside the shell, and plant seaweed on the seaweed cultivation net. When the fishermen use a trawl to catch fish, the trawl touches the shell to make the shell move, and then the upper base moves. The upper base buffers the force received under the action of the piston, and at this time the locking component is locked with the seabed. The seaweed on the seaweed cultivation net increases its grip on the seabed. At the same time, the non-Newtonian fluid layer changes its shape according to the dragging trajectory of the trawl until the trawl is detached from the shell.

[0008] The beneficial effects of the basic solution are: 1. The design of locking the locking assembly to the seabed enhances the stability of the device.

[0009] 2. The design of the seaweed cultivation net enables the device as a whole to be locked twice through the grip of the seaweed, further enhancing the stability of the device.

[0010] 3. When fishermen are fishing, in order to counteract the resistance of water, the trawl is slowly reeled in. At this time, the non-Newtonian fluid layer is relatively soft, and the non-Newtonian fluid will deform under the dragging force of the trawl, guiding the trawl to separate from the shell to a certain extent. At the same time, the non-Newtonian fluid layer will buffer the dragging force of the trawl in the sea water.

[0011] 4. The upper base and the lower base are connected by a piston, so that when the upper base moves under the action of force, the piston can buffer the force on the upper base, and then buffer the force on the outer shell, and then buffer the force on the breeding component, thereby reducing the situation where the breeding component shakes due to the force and causes the coral to fall.

[0012] Furthermore, the shell has a shape of one of a hemispherical shape, a semi-ellipsoidal shape and a teardrop shape.

[0013] The principle and beneficial effect of the basic scheme are: the use of hemispherical, semi-ellipsoidal and teardrop-shaped shell shapes reduces the points of force of the trawl, thereby reducing the situation where the trawl drags the shell.

[0014] Furthermore, the piston comprises a piston cylinder, an upper piston is arranged at one end of the piston cylinder, a lower piston is arranged symmetrically with the upper piston at one end of the piston cylinder away from the upper piston, and a piston cavity is arranged between the upper piston and the lower piston.

[0015] The principle and beneficial effect of the basic solution are: when the upper piston moves upward under the pulling force, the volume of the piston chamber increases, and then the pressure in the piston chamber increases, which increases the force demand of the upper piston during the upward movement. At the same time, the upper piston and the lower piston both have a buffering effect on the force exerted on the upper piston.

[0016] Furthermore, the locking assembly includes a plurality of arc-shaped shovels arranged along the circumference of the bottom of the lower base.

[0017] The principle and beneficial effect of the basic solution are: the design of the arc shovel can improve the overall grip of the device, effectively reducing the possibility of the trawl net dragging the entire device away.

[0018] Furthermore, a plurality of shell holes are provided on the surface of the shell.

[0019] The principle and beneficial effects of the basic solution are as follows: the design of the holes in the outer shell allows seawater to flow inside the device, taking away the oxygen free radicals produced by the corals during photosynthesis. At the same time, coral reef organisms can also enter the device through the holes in the outer shell to find habitats, which also plays an important role in promoting the recovery of the number of coral reef fish.

[0020] Furthermore, the non-Newtonian fluid layer includes rubber, a plurality of fluid layer holes corresponding to the plurality of shell holes are arranged on the rubber surface, a first cavity is arranged inside the rubber, and the first cavity is filled with the non-Newtonian fluid.

[0021] The principle and beneficial effects of the basic solution are: the rubber material is corrosion-resistant and high-strength rubber. The use of this rubber not only ensures the effectiveness of the buffering effect of the non-Newtonian fluid layer, but also reduces the damage to the non-Newtonian fluid layer caused by seawater corrosion and fish impact, thereby increasing the service life of the non-Newtonian fluid layer.

[0022] Furthermore, the breeding components include support rods, the top ends of which are fixedly connected to the inner bottom wall of the shell, and the sides of the adjacent support rods in the horizontal direction that are away from each other are detachably connected with breeding nets, and the breeding nets are detachably connected to the inner bottom wall of the shell.

[0023] The principle and beneficial effects of the basic solution are: the support rods and the inner bottom wall of the shell together support the cultivation net. The vertical design of the cultivation net allows the corals to be fully exposed to the ocean currents during their growth, thereby taking away the oxygen free radicals produced by the corals during photosynthesis.

[0024] Furthermore, the buffer assembly includes elastic buffer plates, which are fixedly connected to the inner wall of the shell, and a plurality of through holes are provided on the surface of the elastic buffer plates.

[0025] The principle and beneficial effects of the basic solution are: when a strong ocean current hits, the elastic buffer plate will buffer the ocean current. At the same time, because a number of through holes are provided on the surface of the elastic buffer plate, part of the ocean current that has been buffered will pass through the elastic buffer plate. The design of the elastic buffer plate reduces the damage to the coral when encountering an overly strong ocean current, and the buffered ocean current can contact the coral through the elastic buffer plate, taking away the oxygen free radicals produced by the coral during photosynthesis, thereby ensuring the normal growth and development of the coral.

[0026] Furthermore, a second cavity is provided inside the lower base, and a growth-promoting component for promoting the growth of corals is placed in the second cavity.

[0027] The principle and beneficial effect of the basic solution are: the design of placing the growth-promoting component inside the second cavity enables the coral to obtain an environment that is more conducive to the growth of the coral during the growth process, thereby promoting the growth and development of the coral.

[0028] Further, the growth promoting assembly includes a plurality of halogen lamps.

[0029] The principle and beneficial effects of the basic program are: light affects the photosynthesis intensity of the symbiotic zooxanthellae in corals, and photosynthesis can produce sugars as the energy source of corals. As for SPS corals, different species of corals have different requirements for light, but in general, all species of SPS corals grow faster under strong light. The use of halogen lamps can ensure faster growth of corals. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following is further described in detail through specific implementation methods:

[0035] The embodiment is basically as shown in the attached Figure 1-Figure 3As shown: an anti-trawling underwater coral ecological restoration device, including a shell 1, the shell 1 is in one of the shapes of a hemisphere, a hemi-ellipsoid and a teardrop, and a surface of the shell 1 is provided with a plurality of shell holes 101, the bottom of the shell 1 is detachably connected to an upper base 2 by bolts, the bottom of the upper base 2 is fixedly connected to a plurality of pistons 4 by bolts, the piston 4 includes a piston cylinder 403, one end of the piston cylinder 403 is slidably connected to an upper piston 401, an end of the piston cylinder 403 away from the upper piston 401 is symmetrically slidably connected to the upper piston 401 and a lower piston 402, a piston cavity 404 is provided between the upper piston 401 and the lower piston 402, the bottom of the lower piston 402 is detachably connected to a lower base 3 by bolts, a second cavity is provided inside the lower base 3, a growth-promoting component is placed in the second cavity, the growth-promoting component includes a plurality of halogen lamps, a locking component 6 for locking the underwater coral ecological restoration device is welded to the bottom of the lower base 3, the locking component 6 includes a plurality of arc-shaped shovels welded along the circumference of the bottom of the lower base 3, and the lower base 3 is buckled along the circumference of its bottom A seaweed cultivation net 5 is connected, and some seaweeds are cultivated on the surface of the seaweed cultivation net 5. A non-Newtonian fluid layer 9 is bonded to the outer wall of the shell 1, and the non-Newtonian fluid layer 9 includes rubber 902. A plurality of fluid layer holes 901 corresponding to the plurality of shell holes 101 are arranged on the surface of the rubber 902. A first cavity 903 is arranged inside the rubber 902, and the first cavity 903 is filled with a non-Newtonian fluid. A plurality of buffer components for buffering ocean currents and a plurality of cultivation components for coral cultivation are fixedly connected by bolts at equal intervals on the two inner side walls of the shell 1. The cultivation components include support rods 701, and the top ends of the support rods 701 are fixedly connected with the inner bottom wall of the shell 1 by bolts. The sides of the adjacent support rods 701 in the horizontal direction that are away from each other are detachably connected with cultivation nets 702 by bolts, and the cultivation nets 702 are detachably connected with the inner bottom wall of the shell 1 by bolts. The buffer components include elastic buffer plates 801, and the elastic buffer plates 801 are fixedly connected with the inner wall of the shell 1 by bolts, and a plurality of through holes 802 are arranged on the surface of the elastic buffer plates 801.

[0036] The specific implementation process is as follows: the staff first presses the arc shovel into the seabed. Because the lower base 3 is welded to the arc shovel, the lower base 3 is fixed above the seabed by the arc shovel. Then the staff connects the upper base 2, the piston 4 and the lower base 3 by bolting, and then fixes the seaweed cultivation net 5 with seaweed culture around the lower bottom by buckles, and fixes the shell 1 and the upper base 2 by bolts. Then the staff enters the shell 1 to install the cultivation components and the buffer components: the staff first places the support rod 701 equidistantly on the inner bottom wall of the shell 1, and uses bolts to fix the top of the support rod 701 to the inner bottom wall of the shell 1, and then bolts the cultivation net 702 to the inner bottom wall of the shell 1 and the side of the support rod 701 close to the inner bottom wall of the shell 1. At this time, the installation of the cultivation components is completed; then the staff uses bolts to fix the elastic buffer plate 801 equidistantly on the inner bottom wall of the shell 1 to complete the installation of the buffer component.

[0037] Fishermen may use trawling when fishing, so that the housing 1 may come into contact with the trawling net. When the trawling net drives the housing 1 to move, the upper base 2 will also move together. At this time, under the buffering effect of the piston 4, the lower base 3 will move towards the upper base 2. At this time, the arc shovel will lock with the seabed, so that the lower base 3 is also locked. At the same time, the seaweed cultivation net 5 will lock the lower base 3 for a second time under the action of the seaweed grip, further reinforcing the lower base 3, thereby reinforcing the overall stability of the device.

[0038] When fishermen are performing salvage operations, in order to resist the resistance of water, they will slowly pull up the trawl net. When the trawl net touches the outer shell 1, since the trawl net is slowly pulled up, the non-Newtonian fluid layer 9 is relatively soft at this time, and the shape of the non-Newtonian fluid layer 9 will change according to the dragging conditions of the trawl net. Then, the non-Newtonian fluid layer 9 will buffer the force applied by the trawl net to the outer shell 1, and under the change of the shape of the non-Newtonian fluid layer 9, the trawl net will eventually be guided away from the outer shell 1 to a certain extent.

[0039] When the school of fish hits the non-Newtonian fluid layer 9 at a slower speed, the non-Newtonian fluid layer 9 is softer and causes less damage to the school of fish, thereby reducing the damage to the school of fish; when the school of fish hits the non-Newtonian fluid layer 9 quickly, the non-Newtonian fluid layer 9 becomes hard, thereby reinforcing the device as a whole, reducing the deterioration of the device stability caused by the rapid impact of the school of fish, while enhancing the stability of the device.

[0040] During the growth and development of corals, coral reef fish can enter the interior of the housing 1 through the fluid layer holes 901 and the housing holes 101. The corals can provide a habitat for the coral reef fish, and the coral reef fish can remove parasites and dead skin for the corals. The symbiotic relationship formed between the coral reef fish and the corals is conducive to the growth of the corals and provides a favorable environmental factor for the growth and development of the corals. The use of halogen lamps can ensure that the corals can carry out more photosynthesis and obtain more energy, thereby accelerating the growth and development of the corals, and further providing a favorable environmental factor for the growth and development of the corals.
