[0001] The present invention relates to the technical field of artificial fish reefs, in particular to an artificial fish reef. Background Art

[0002] Artificial reefs are effective structures set up on the seabed to create a good habitat for fish, shrimp and other marine life, so as to achieve the purpose of protecting and increasing fishery resources. Artificial reefs can purify the seawater environment, change the direction of seawater flow, form upwelling, and facilitate fish feeding, retention and aggregation.

[0003] At present, artificial reefs are generally used to improve the habitat of fish and other marine organisms, but there is still a lack of design and research on improving sediment movement and other functions. Currently, the functions of artificial reefs are generally relatively simple, with simple structural types, such as diversion type, ladder type, M type, etc.

[0004] However, artificial reefs with a single structure have poor stability on the seabed surface and are prone to tipping over in sea areas with large seabed undulations and high current speeds. In addition, these artificial reefs placed around wind farms will also cause increased scouring around the wind farms, posing a threat to the safe operation of the wind farms. Summary of the invention

[0005] The present invention provides an artificial fish reef to solve the problem in the related art that the artificial fish reef is easy to topple over, thus posing a threat to the safe operation of a wind farm.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 3 As shown, an embodiment of the present invention provides an artificial fish reef, which includes a chassis 10, fixed piles 20 and a habitat 30. The chassis 10 has a seabed contact surface 11, the fixed piles 20 are arranged on the chassis 10 and extend downward, the fixed piles 20 can be inserted into and fixed to the seabed 60, and the habitat 30 is arranged on the chassis 10. The habitat 30 has a habitat cavity and an opening structure 31 connected to the habitat cavity.

[0030] The artificial fish reef provided in this embodiment is applied. The artificial fish reef includes a chassis 10, a fixed pile 20 and a habitat 30. By placing the artificial fish reef in the sea area, the opening structure 31 facilitates the entry and exit of marine organisms such as fish and shrimps, provides a habitat for marine organisms such as fish, and can achieve fish farming and purify the marine environment. Even in sea areas with large seabed fluctuations and large current speeds, since the fixed pile 20 is inserted and fixed into the seabed 60, the chassis 10 is pressed on the surface of the seabed 60, which can prevent the seabed 60 under the chassis 10 from being eroded and loosened by the water flow, and prevent the artificial fish reef from tipping over. The fixed pile 20 provides a supporting force to fix the artificial fish reef on the surface of the seabed without tipping over. The artificial fish reef provided in this embodiment effectively solves the problem in the related art that artificial fish reefs are prone to tipping over, posing a threat to the safe operation of wind farms.

[0031] Furthermore, the habitat chamber 30 can further slow down the water flow speed in the area, further reduce the silt scouring in the area, and be more conducive to the habitat and predation of marine organisms in the area.

[0032] Specifically, the outer shape of the habitat 30 can be a cylinder, a cube, a trapezoid, a polygonal prism or the like, the opening structure 31 can be a square, a circle, a triangle, a polygon or the like or a combination of multiple shapes, and the fixing pile 20 can be a square prism or a cylinder.

[0033] like Figure 1 As shown, the artificial fish reef also includes a wave-breaking structure 40 arranged on the upper surface of the chassis 10. The wave-breaking structure 40 absorbs water flow energy and wave energy on the seabed surface to play a wave-breaking role. At the same time, it can reduce the tidal flow rate, reduce the erosion of the seabed by wave power, and promote the sedimentation of mud and sand carried in the seawater, thereby achieving the effect of sand fixation and siltation promotion.

[0034] Specifically, the wave-breaking structure 40 can undergo elastic deformation after receiving water flow energy and wave energy from the seabed surface, so as to reduce tidal current velocity and wave energy.

[0035] like Figure 1 As shown, the wave-breaking structure 40 includes a bionic grass structure 41 disposed on the upper surface of the chassis 10. The bionic grass structure 41 deforms to absorb the water flow energy and wave energy on the seabed surface, plays a wave-breaking role, and can also reduce the tidal flow velocity, reduce the erosion of the seabed by wave power, and promote the sedimentation of the silt carried in the seawater, thereby achieving the effect of sand fixation and siltation promotion.

[0036] like Figure 2 As shown, the bionic grass structure 41 includes at least two bionic grass rings 411, which are arranged around the outside of the habitat 30, and at least two bionic grasses are arranged in sequence in the inner and outer directions of the habitat 30, and the bionic grass ring 411 includes a plurality of bionic grass monomers 4111 arranged along the circumference of the chassis 10. The bionic grass structure 41 with the above structure can improve the wave-breaking range and wave-breaking effect of the wave-breaking structure 40.

[0037] In this embodiment, the height of the bionic grass structure 41 is less than or equal to the lowest water level of the sea area where the artificial fish reef is located.

[0038] like Figures 1 to 3 As shown, the artificial reef also includes a connecting pile 50 and a flexible power generation member 51. The connecting pile 50 is arranged on the habitat 30 and extends upward. The flexible power generation member 51 is arranged on the connecting pile 50. The flexible power generation member 51 has a liquid surface matching portion. The rise and fall of the water depth acts on the flexible power generation member 51, and the flexible power generation member 51 is deformed to convert the received tidal energy and wave energy into pressure energy, and then into electrical energy.

[0039] like Figure 3 As shown, the flexible power generation element 51 includes a slide tube and a jellyfish-like cover 511. The slide tube is movably mounted on the connecting pile 50 along the extension direction of the connecting pile 50. The middle part of the jellyfish-like cover 511 protrudes upward. The jellyfish-like cover 511 is mounted on the slide tube and connected to the slide tube. The outer surface of the jellyfish-like cover 511 forms a liquid surface matching portion. With the flexible power generation element 51 of the above structure, when the water level changes, the buoyancy of the jellyfish-like cover 511 changes, so as to drive the slide tube to rise and fall together with the jellyfish-like cover 511, until the buoyancy of the jellyfish-like cover 511 is balanced with the gravity of the jellyfish-like cover 511 and the slide tube, so that the flexible power generation element 51 can change with the change of the water level, and avoid the liquid surface matching portion from being separated from the water surface, so as to ensure that the flexible power generation element 51 can capture tidal energy before and after the water level changes.

[0040] Specifically, the jellyfish-like cover 511 is made of a power-generating film or piezoelectric ceramic material of a certain thickness.

[0041] The flexible power generation element 51 includes at least two jellyfish-like covers 511, which are arranged along the axial direction of the slide tube, and at least two jellyfish-like covers 511 are sleeved on the outer side of the slide tube. The use of the at least two jellyfish-like covers 511 can increase the range of energy absorption of the flexible power generation element 51 in the height direction, and the lowest height of the lowest jellyfish-like cover 511 is less than or equal to the lowest water level of the sea area where the artificial reef is located.

[0042] In this embodiment, a slide rail extending along the extension direction of the connecting pile 50 is provided on the side wall of the connecting pile 50, and a sliding portion matching the slide rail is provided on the slide cylinder. When the slide cylinder slides along the extension direction of the connecting pile 50, the slide cylinder is prevented from rotating around the axis of the connecting pile 50, so as to improve the energy recovery of tidal energy and blade waves by the flexible power generation device.

[0043] In this embodiment, the artificial fish reef also includes a linkage rope, which is passed through the connecting pile 50 and the chassis 10. The two ends of the linkage rope are respectively connected to the slide and the bionic grass monomer 4111. During the lifting and lowering process of the slide, the slide drives the linkage rope to retract and release the bionic grass monomer 4111 to change the height of the bionic grass monomer 4111.

[0044] In this embodiment, an energy storage component is disposed in the connection pile 50 , and the energy storage component is electrically connected to the flexible power generation component 51 to store the electric energy converted by the flexible power generation component 51 .

[0045] Specifically, the energy storage device is electrically connected to surrounding small devices such as floats to provide electrical energy. The energy storage device can also be electrically connected to a nearby wind turbine through a cable to transmit electricity to the outside through the wind turbine's transmission line or supply electricity to related internal power equipment of the wind turbine.

[0046] In this embodiment, the diameter of the connecting pile 50 is smaller than the diameter of the habitat chamber 30. Specifically, the connecting pile 50 is disposed through the habitat chamber 30 and is connected to the habitat chamber 30 and the chassis 10 respectively. The ratio of the diameter of the connecting pile 50 to the diameter of the habitat chamber 30 is between 0.3 and 0.7. By using the connecting pile 50 within the above diameter range, the radial space of the habitat chamber can be increased while ensuring the structural reliability of the connecting pile 50.

[0047] Preferably, the ratio of the diameter of the connecting pile 50 to the diameter of the habitat 30 is 0.5.

[0048] In this embodiment, the artificial fish reef includes at least four fixed piles 20 arranged in the circumferential direction of the chassis 10, and the at least four fixed piles 20 are inserted into and fixed to the seabed 60. The chassis 10 is pressed on the surface of the seabed 60 to improve the placement stability of the artificial fish reef.

[0049] In this embodiment, the diameter of the chassis 10 is greater than or equal to the diameter of the habitat chamber 30, which improves the placement stability of the artificial fish reef and stabilizes the seabed plane around the habitat chamber 30 to prevent turbulence from stirring the seabed plane around the habitat chamber 30 when marine organisms enter and exit the habitat chamber 30.

[0050] In this embodiment, the opening structures 31 are arranged in a plurality in the circumferential direction of the habitat chamber 30 to meet the habitat needs of marine organisms. The plurality of opening structures 31 may be evenly distributed or unevenly distributed in the circumferential direction of the habitat chamber 30 .

[0051] In this embodiment, the diameter of the opening structure 31 is greater than or equal to 100 mm to meet the habitat requirements of marine organisms.

[0052] The artificial fish reef provided in this embodiment can be used near a single pile foundation, a jacket foundation or a pile barrel foundation. A certain number of them can be deployed. The artificial fish reef structure is highly functional, easy to install, and has significant effects. It can bring economic benefits while stabilizing the seabed surface, providing protection for the safe operation of offshore wind power.
