Technical Field

[0001] The invention relates to the technical field of artificial fish reefs, and in particular to a floating fish reef with a jellyfish-like structure. Background Art

[0002] Artificial reefs are a type of artificially constructed underwater equipment, mainly used to improve the marine ecological environment (artificial reefs provide marine organisms with habitats similar to natural reefs. Many marine organisms, such as fish, shellfish, algae, etc., need to attach or hide in the habitat to avoid natural enemies, reproduce and feed), increase fishery resources (artificial reefs can attract and gather fish, provide them with food and habitats, thereby increasing the reproduction rate and survival rate of fish) and protect marine biodiversity.

[0003] Traditional artificial reefs are made of reinforced concrete structures with several holes on them to increase porosity and permeability to form reefs. The above-mentioned artificial reefs are mainly submerged reefs used to attract bottom-layer fish in the ocean, while there are relatively few reefs for attracting mid- and upper-layer fish. Fish are mainly attracted by setting up shade structures underwater. They do not incorporate the principles of bionics and are not very effective in attracting fish. Summary of the Invention

[0006] Preferably, the strip tentacles include a plurality of braided belts and a plurality of buoyancy balls, the buoyancy balls are made of silicone material, the plurality of braided belts and the plurality of buoyancy balls are alternately connected in series, and the topmost braided belt is located in the through hole.

[0008] Preferably, an attachment groove is provided on the surface of the buoyancy ball, and a degradable food-attracting fiber is provided on the surface of the braided belt.

[0009] Preferably, the woven belt located in the through hole is fixedly connected to a hinged ball, a limiting groove for limiting the hinged ball is provided in the through hole, there is a gap between the surface of the hinged ball and the limiting groove, and a plurality of inclined guide plates are fixedly connected to the top of the hinged ball, and the plurality of guide plates are all placed in the through hole.

[0010] Preferably, the connecting cable group includes a central cable and several main cables, one end of each of the main cables is hinged to the bottom of the buoyancy tank, and the other end converges to the central cable, and the central cable is fixedly connected to the anchor assembly.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: a floating fish reef with a jellyfish-like structure of the present invention, the buoyancy cabin provides overall buoyancy to ensure that the fish reef is suspended in the target water layer, and the jellyfish shape is simulated by the combination of a load-bearing ring and vertical strip tentacles. The hinged design of the strip tentacles enables them to swing naturally in the ocean current, enhancing the visual appeal to fish, and is automatically triggered by wave energy. The wave-facing plate pushes the arc-shaped moving plate under the impact of waves, and releases kinetic energy after storing energy through the spring, driving the extrusion ring to press down periodically. Water pressure will flow in through the through-hole, thereby forcing the strip tentacles to vibrate at a high frequency to simulate the movement pattern of jellyfish when escaping from natural enemies, effectively improving the dynamic attracting effect on fish, and the anchoring assembly is connected by a connecting cable group, which ensures the stability of the fish reef position while allowing it to swing limitedly under the action of waves, avoiding structural damage caused by rigid fixation, solving the problem that traditional bottom-sunken fish reefs cannot effectively attract upper-layer fish. The synergistic effect of the floating structure and wave response makes the fish reef a "living" habitat, improving the efficiency of fish aggregation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is combined with Figures 1 to 5 In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention.

Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, but do not exclude other elements or objects.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly. The drawings in the present invention are not drawn strictly according to the actual scale. The specific size and quantity of each structure can be determined according to actual needs. The drawings described in the present invention are only structural schematic diagrams.

[0022] The present invention provides a jellyfish-like floating fish reef, such as Figures 1 to 4As shown, it includes a buoyancy tank 1, a plurality of vertically suspended strip tentacles 2 are provided at the bottom of the buoyancy tank 1, and an anchoring assembly 4 is connected to the buoyancy tank 1 through a connecting cable group 3. A load-bearing ring 5 is fixedly connected to the bottom of the buoyancy tank 1, and a plurality of strip tentacles 2 are evenly distributed at the bottom of the load-bearing ring 5. The load-bearing ring 5 is provided with a plurality of through holes 6 arranged one-to-one corresponding to the strip tentacles 2, and the top of the strip tentacles 2 is located in the through holes 6; a pair of arc-shaped movable plates 7 are fitted on the buoyancy tank 1, and the pair of arc-shaped movable plates 7 are connected to the buoyancy tank 1 through a rotating shaft. A wave-facing plate 10 is fixedly connected to the pair of arc-shaped movable plates 7, and a fixed plate 8 is fixedly connected to the center position of the top of the buoyancy tank 1. The wave-facing plate 10 and the fixed plate 8 are connected by a spring 9. A pair of arc-shaped movable plates 7 are fixedly connected to the side close to the load-bearing ring 5. When the extrusion ring 11 moves toward the side of the load-bearing ring 5, the water flow will be pressed into the through holes 6, thereby causing the strip tentacles 2 to swing.

[0023] The buoyancy chamber 1 provides overall buoyancy to ensure that the fish reef is suspended in the target water layer. The combination of the load-bearing ring 5 and the vertical strip tentacles 2 simulates the shape of jellyfish. The hinged design of the strip tentacles 2 allows them to swing naturally in the ocean current, enhancing the visual appeal to fish. It is also automatically triggered by wave energy. The wave-facing plate 10 pushes the arc-shaped moving plate 7 under the impact of waves, and releases kinetic energy after storing energy through the extrusion spring 9, driving the extrusion ring 11 to press down periodically. The water pressure will flow in through the through hole 6, thereby forcing the strip tentacles 2 to vibrate at a high frequency to simulate the movement pattern of jellyfish when escaping from natural enemies, effectively improving the dynamic attracting effect on fish. The anchoring assembly 4 is connected by the connecting cable group 3, which ensures the stability of the fish reef position while allowing it to swing limitedly under the action of waves to avoid structural damage caused by rigid fixation. This solves the problem that traditional bottom-sunken fish reefs cannot effectively attract upper-layer fish. The synergistic effect of the floating structure and wave response makes the fish reef a "living" habitat, improving the efficiency of fish aggregation.

[0024] Preferably, Figure 1~Figure 2 As shown, the strip-shaped tentacle 2 includes a plurality of braided belts 201 and a plurality of buoyancy balls 202 . The buoyancy balls 202 are made of silicone. The plurality of braided belts 201 and the plurality of buoyancy balls 202 are alternately connected in series, and the topmost braided belt 201 is located in the through hole 6 .

[0025] In this embodiment, the braided belt 201 is made of ultra-high molecular weight polyethylene, which has high tensile strength and can withstand the impact of ocean currents and the bites of large fish, thereby extending the service life of the entire device. The buoyancy ball 202 is made of flexible silicone material to simulate the soft characteristics of real jellyfish tentacles to avoid damaging the fish body. Its buoyancy characteristics ensure that the tentacles maintain a vertical hanging posture. Several braided belts 201 and several buoyancy balls 202 are alternately connected in series to increase the surface area of ​​the strip tentacles 2, providing an attachment base for algae and shellfish, and forming a micro-ecological community.

[0026] Preferably, Figure 1~Figure 2The length of the braided belt 201 increases from top to bottom, and the diameter of the buoyancy ball 202 decreases from top to bottom.

[0027] In this embodiment, the length of the braided belt 201 increases from top to bottom, and the diameter of the buoyancy ball 202 decreases from top to bottom. The long braided belt 201 covers the deep water layer, and the short braided belt 201 covers the shallow layer, forming a vertical habitat gradient to meet the layered habitat needs of different fish. The gradient structure reduces eddy resistance, avoids the entanglement of the strip tentacles 2, and ensures that it maintains a stable shape in strong currents. The buoyancy ball 202 with decreasing diameter simulates the morphological transition from juvenile jellyfish to adult jellyfish, enhancing its natural attraction to fish. The gradient design expands the effective habitat volume of the fish reef and prolongs the retention time of target fish.

[0028] Preferably, Figure 5 As shown, an attachment groove 12 is provided on the surface of the buoyancy ball 202, and a degradable food-attracting fiber is provided on the surface of the braided belt 201.

[0029] In this embodiment, an attachment groove 12 is provided on the surface of the buoyancy ball 202, and a honeycomb groove design with a depth of 2mm-5mm increases the surface roughness, promotes the attachment of barnacles, algae, etc., and the biological coverage rate reaches more than 80% within 6 months, forming a natural bait reservoir; the surface of the woven belt 201 is provided with degradable attractant fiber, which can be made of corn protein or chitin, and continuously releases attractants such as glycine and nucleotides. The dual effects of biological attachment and chemical attraction upgrade the fish reef from a "passive habitat" to an "active fattening ground", thereby increasing the weight gain rate of fish.

[0030] Preferably, Figure 2~Figure 3 As shown, the woven belt 201 located in the through hole 6 is fixedly connected to the articulated ball 13, and a limiting groove 14 for limiting the articulated ball 13 is provided in the through hole 6. There is a gap between the surface of the articulated ball 13 and the limiting groove 14. Several inclined guide plates 16 are fixedly connected to the top of the articulated ball 13, and several guide plates 16 are all placed in the through hole 6.

[0031] In this embodiment, the gap between the limiting groove 14 of the articulated ball 13 allows the strip tentacles 2 to swing in multiple directions in the wind and waves, avoiding breakage caused by rigid connection. The guide plate 16 is arranged at an angle on the top of the articulated ball 13 to divert high-speed water flow and reduce the vortex-induced vibration of the load-bearing ring 5, thereby solving the structural failure problem of floating fish reefs under harsh sea conditions and being maintenance-free during the life cycle.

[0032] Preferably, Figures 1 to 4As shown, the connecting cable group 3 includes a central cable 301 and several main cables 302. One end of the main cables 302 is evenly hinged to the bottom of the buoyancy chamber 1, and the other end converges to the central cable 301. The central cable 301 is fixedly connected to the anchor assembly 4. The anchor assembly 4 is configured as a terraced concrete sinker with several guide grooves 15 on the surface. The surface of the central cable 301 is provided with an anti-bite sleeve 17, and the anti-bite sleeve 17 is woven with a stainless steel woven mesh.

[0033] In this embodiment, the main cable 302 is evenly hinged to disperse the tension and avoid single-point stress fracture; the center cable 301 concentrates stress and reduces the risk of overturning of the anchor base. The stepped concrete base and the guide groove 15, the stepped shape enhances the seabed grip, and the guide groove 15 reduces bottom mud accumulation to ensure long-term positioning accuracy. The surface of the center cable 301 is provided with a stainless steel woven anti-bite sleeve 17 to resist scratches from sharks and ships, extend the life of the cable, and reduce maintenance costs.

[0034] The method for using the jellyfish-like floating fish reef of the present invention is as follows: According to the marine environment of the target waters and the target fish species, the weight of the anchor base is selected to suit the target. By adjusting the buoyancy of the buoyancy chamber 1, the strip tentacles 2 are controlled to float in the target water layer. The central cable 301 of the connecting cable group 3 is fixed to the anchor base, and multiple main cables 302 are evenly hinged to the bottom of the buoyancy chamber 1 to form an umbrella-shaped traction structure. Figure 4 shown.

[0035] When waves hit the wave-facing plate 10, the arc-shaped movable plate 7 is pushed to slide along the surface of the buoyancy chamber 1, compressing the extrusion spring 9 to store energy. When the extrusion spring 9 is compressed to the critical point, the extrusion spring 9 quickly releases kinetic energy, driving the arc-shaped movable plate 7 to move in the opposite direction, and driving the extrusion ring 11 to squeeze the surface of the carrying ring 5 downward.

[0036] The squeezing ring 11 presses down to force the water in the carrying ring 5 to pass through the through hole 6 to form a high-speed water flow. Figure 3 As shown, the water flow hits the hinge ball 13 at the top of the strip-shaped tentacle 2. Due to the gap between the hinge ball 13 and the limiting groove 14, the strip-shaped tentacle 2 produces multi-directional high-frequency jitter, simulating the movement of a jellyfish escaping from its natural enemy.

[0037] The shaking of the strip tentacles 2 creates visual stimulation, attracting middle and upper layer fish to gather. The attachment grooves 12 on the surface of the buoyancy ball 202 promote the attachment of algae and barnacles, forming a natural bait reservoir. The degradable attractant fiber on the surface of the braided belt 201 continuously releases amino acid substances, expanding the attracting radius to 50 meters.

[0038] In ocean currents, the gradually varying length braided belt 201 and the gradually varying diameter buoyancy ball 202 reduce eddy resistance, preventing the strip tentacles 2 from being entangled with the stainless steel anti-bite sleeve 17 on the surface of the central cable 301 to resist shark bites; the guide groove 15 of the terraced anchor base reduces silt accumulation and prevents displacement, and the guide plate 16 in the through hole 6 diverts high-speed water flow to reduce the vibration of the carrying ring 5.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
