Description

Technical Field

[0001] This invention belongs to the field of artificial reef technology, specifically relating to a green artificial reef that prevents siltation. Background Technology

[0002] Marine artificial reef models are an important means of marine ecological protection and fishery resource enhancement. By simulating the structure of natural reefs, they provide marine life with places to reproduce, inhabit, and forage, thereby promoting the balance and diversity of marine ecosystems.

[0003] Currently, most artificial reefs are cubic frame-type structures made of construction waste cement or reinforced concrete. However, after these frame-type artificial reefs sink to the bottom, the sediment at the bottom is disturbed by the water flow and covers the beams of the frame-type artificial reef, causing partial burial of the reef. This results in the loss of bottom habitat and a reduction in the cross-sectional area of ​​fish swimming channels, thus reducing the efficiency of attracting fish. Furthermore, under ideal conditions, the frame should generate periodic Karman vortex streets to attract schooling fish. After the artificial reef is partially buried, the intensity of the vortex street decreases and the vortex shedding frequency becomes unstable, further reducing the efficiency of attracting fish.

[0004] Therefore, a green artificial reef that prevents siltation is needed to solve the above problems. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a green artificial reef that is protected from siltation, thereby solving the problem of poor fish-attracting efficiency caused by partial burial of artificial reefs in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a green artificial reef to prevent siltation, comprising a hemispherical counterweight. A first annular frame is fixedly connected to the top wall of the counterweight. A first annular rubber body with a U-shaped cross-section is fixedly installed on the peripheral wall of the first annular frame. The first annular rubber body is sealed and fixedly connected to the counterweight. The diameter of the first annular rubber body is larger than the diameter of the counterweight. Multiple support rods are circumferentially fixedly connected to the counterweight on the inner side of the first annular frame, centered on the counterweight's axis. A second annular frame is fixedly connected to the top of each support rod. The diameter of the second annular frame is smaller than the diameter of the first annular frame. A second annular rubber body with a U-shaped cross-section is provided on the outer peripheral wall of the second annular frame. The diameter of the second annular rubber body is smaller than the diameter of the first annular rubber body.

[0007] Furthermore, both the first and second annular frames include two circular and coaxially arranged supports, which are fixedly connected by a connecting rod. The supports and the support rods on the second annular frame are coaxially arranged in a one-to-one correspondence.

[0008] Furthermore, a rotating ring is rotatably provided on the outer wall of the support on the second annular frame, and the rotating ring is fixedly connected to the second annular rubber body.

[0009] Furthermore, multiple guide fins are fixedly arranged circumferentially on the outer peripheral wall of the second annular rubber body with the axis of the second annular rubber body as the center.

[0010] Furthermore, the counterweight has a cavity, and a rubber sealing gasket that can seal the cavity is fixedly installed on the top wall of the counterweight. A slider that can slide along the axial direction of the counterweight is slidably installed in the cavity. A spring is fixedly connected between the slider and the bottom wall of the cavity. An annular groove is provided in the bracket on the second annular frame. The rotating ring is closed in the annular groove. The connecting rod and support rod on the second annular frame are hollow. Multiple gears corresponding to the support rods are rotatably connected in the annular groove. A gear ring that meshes with the gear is fixedly connected to the rotating ring. A rotating shaft that extends from the inside of the support rod to the bottom wall of the cavity is fixedly connected to the gear. A drive sleeve is fixedly connected to the rotating shaft. A limiting groove that cooperates with the drive sleeve is provided on the bottom wall of the slider. Rotating the drive sleeve can make the slider reciprocate axially to impact the rubber sealing gasket.

[0011] Furthermore, the drive sleeve is coaxially arranged with the rotating shaft, the drive sleeve is fixedly sleeved on the rotating shaft, and a protrusion is fixedly provided on the top wall of the drive sleeve, the protrusion being smoothly arranged with the top wall of the drive sleeve.

[0012] Furthermore, the top wall of the slider is rounded, and the upward movement of the slider can compress the rubber sealing gasket to deform it.

[0013] The beneficial effects of this invention are as follows: This invention uses hemispherical counterweights to lower the center of gravity of the artificial reef, preventing it from tipping over like a "roly-poly toy" and providing a multi-scale habitat. The annular hollow structure of the rubber rings creates a composite vortex system, continuously generating turbulent fields that attract schooling fish. The hollow features of the first and second annular rubber rings improve space utilization. Because the rubber rings have buoyancy at the bottom, the counterweights sink the two rings to the bottom. Under strong water currents, the rings float in balance with the counterweights, preventing the accumulation of silt around the counterweights over time. Under weak water currents, the water impacts the second annular rubber ring, causing the artificial reef to tilt. Once the water calms, the "roly-poly toy" characteristic allows the artificial reef to return to its original position. When placing the artificial reef, the counterweights ensure that the reef lands with the counterweight facing downwards. The entire device is made from demolition waste, making it green, low-carbon, and cost-effective.

[0014] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0016] The following components are labeled in the attached diagram: counterweight 1, cavity 101, slider 102, spring 103, piezoelectric ceramic sheet 104, pressure plate 105, sound wave generator 106, limiting groove 107, first annular frame 2, bracket 201, connecting rod 202, first annular rubber body 3, rubber sealing gasket 4, support rod 5, second annular frame 6, rotating ring 601, annular groove 602, gear 603, gear ring 604, rotating shaft 605, drive sleeve 606, protrusion 607, second annular rubber body 7, and guide fin 701. Detailed Implementation

[0017] like Figures 1-3 As shown, the present invention provides a green artificial reef to prevent siltation, comprising: a hemispherical counterweight 1, a first annular frame 2 fixedly connected to the counterweight 1, a first annular rubber body 3 with a U-shaped cross-section fixedly installed on the periphery of the first annular frame 2, the first annular rubber body 3 being tire-shaped, the first annular rubber body 3 being sealed and fixedly connected to the counterweight 1, the diameter of the first annular rubber body 3 being larger than the diameter of the counterweight 1, a plurality of support rods 5 being fixedly connected circumferentially around the axis of the counterweight 1 on the inner side of the first annular frame 2, a second annular frame 6 being fixedly connected to the top of the support rods 5, the diameter of the second annular frame 6 being smaller than the diameter of the first annular frame 2, and a second annular rubber body 7 with a U-shaped cross-section provided on the outer periphery of the second annular frame 6, the diameter of the second annular rubber body 7 being smaller than the diameter of the first annular rubber body 3.

[0018] In this design, both the first annular frame 2 and the second annular frame 6 include two circular and coaxially arranged supports 201, which are fixedly connected by connecting rods 202. The first annular rubber body 3 and the second annular rubber body 7 can be made from discarded tires. The counterweight 1, the first annular frame 2, and the second annular frame 6 can be made from solid waste concrete from demolished buildings. The supports 201 on the second annular frame 6 are coaxially arranged in a one-to-one correspondence with the support rods 5. This design uses a hemispherical counterweight 1 to lower the overall center of gravity of the artificial reef, preventing it from tipping over like a "roly-poly toy." The hemispherical shape of the counterweight 1 also increases the gap between the first annular frame 2 and the seabed, preventing silt burial. The two annular rubber bodies, the two annular frames, and the support rods 5 together form a space for fish activity, providing multi-scale... The artificial reef has a suitable habitat; the hollow annular structure of the rubber body can form a complex vortex system, which can continuously generate a turbulent field that fish like to attract schooling fish. The hollow features of the first annular rubber body 3 and the second annular rubber body 7 improve the space utilization. Since the rubber body has a certain buoyancy at the bottom of the water, the two annular rubber bodies are sunk to the bottom of the water by the counterweight 1. Under the action of strong water flow, the annular rubber bodies and the counterweight 1 can float in balance, which can prevent the silt from slowly accumulating around the counterweight 1 due to long-term water flow. Under the action of weak water flow, the water flow can impact the second annular rubber body 7 to tilt the artificial reef. After the water flow stabilizes, the artificial reef returns to its original position due to the "roly-poly" feature. When placing the artificial reef, the counterweight 1 can make the artificial reef fall to the bottom of the water with the counterweight 1 facing downwards.

[0019] In one embodiment of the present invention, a rotating ring 601 is rotatably provided on the outer wall of the support 201 on the second annular frame 6. The rotating ring 601 is fixedly connected to the second annular rubber body 7. A plurality of guide fins 701 are fixedly provided on the outer peripheral wall of the second annular rubber body 7 with the axis of the second annular rubber body 7 as the center.

[0020] In this scheme, under the action of water flow, the second annular rubber body 7 can be rotated by the guide fin 701 to generate an unsteady Karman vortex street. When rotating, the frequency range of the vortex street expands, and the fish-attracting efficiency is improved through dynamic fluid signals. In special application environments (such as algae-rich environments), the rotation of the second annular rubber body 7 can increase water disturbance and enhance turbulence intensity, destroy the red tide algae aggregation structure, and create a biological behavior training ground to enhance the vitality of the reef ecosystem.

[0021] In one embodiment of the present invention, a cavity 101 is provided inside the counterweight 1, and a rubber sealing gasket 4 capable of sealing the cavity 101 is fixedly provided on the top wall of the counterweight 1. A slider 102 capable of sliding along the axial direction of the counterweight 1 is slidably provided inside the cavity 101, and a spring 103 is fixedly connected between the slider 102 and the bottom wall of the cavity 101. An annular groove 602 is provided inside the bracket 201 on the second annular frame 6, and the rotating ring 601 is provided to close the annular groove 602. The connecting rod 202 and the support rod 5 on the second annular frame 6 are both hollow. The annular groove 602 is rotatably connected to a plurality of gears 603 corresponding one-to-one with the support rod 5. The rotating ring 601 is fixedly connected to a gear ring 604 that meshes with the gears 603. The gears 603 are fixedly connected to a rotating shaft 605 that extends from the inside of the support rod 5 to the bottom wall of the cavity 101. The rotating shaft 605 is fixedly connected to a drive sleeve 606. The bottom wall of the slider 102 is provided with a limiting groove 107 that cooperates with the drive sleeve 606. Rotating the drive sleeve 606 can make the slider 102 reciprocate axially to impact the rubber sealing gasket 4.

[0022] In this scheme, when the water flow drives the second annular frame 6 to rotate, it drives the rotating ring 601 to rotate, which in turn drives the gear 603 to rotate through the toothed ring 604, thereby driving the rotating shaft 605 and the drive sleeve 606 to rotate, which in turn drives the slider 102 to reciprocate so that the slider 102 hits the rubber sealing gasket 4, causing the mud and sand that fell into the first annular rubber body 3 to scatter and be flushed out of the first annular rubber body 3 under the action of the water flow.

[0023] In one embodiment of the present invention, the drive sleeve 606 is coaxially arranged with the rotating shaft 605, the drive sleeve 606 is fixedly sleeved on the rotating shaft 605, and the top wall of the drive sleeve 606 is provided with a protrusion 607, which is smoothly arranged with the top wall of the drive sleeve 606.

[0024] In this design, the limiting groove 107 cooperates with the driving sleeve 606. When the protrusion 607 on the driving sleeve 606 cooperates with the top wall of the limiting groove 107, the slider 102 is at its lowest point. When the driving sleeve 606 is rotated so that the protrusion 607 cooperates with the top wall of the limiting groove 107, the slider 102 is at its highest point. During the continuous rotation of the driving sleeve 606, the slider 102 is in a continuous reciprocating rotation process under the action of the spring 103, thereby pushing the rubber sealing gasket 4 to deform so that the mud or fish excrement falling on the rubber sealing gasket 4 flows out with the water flow from the first annular rubber body 3.

[0025] In one embodiment of the present invention, the top wall of the slider 102 is arranged in an arc shape, and the slider 102 can squeeze the rubber sealing gasket 4 to deform the rubber sealing gasket 4 when it moves upward.

[0026] In one embodiment of the present invention, a sound wave generator 106 is installed on the counterweight 1, a piezoelectric ceramic sheet 104 electrically connected to the sound wave generator 106 is installed on the bottom wall of the cavity 101, and a pressure plate 105 that cooperates with the piezoelectric ceramic sheet 104 is provided on the bottom wall of the slider 103. The slider 103 can squeeze the piezoelectric ceramic sheet 104 and generate an electric charge by sliding downward. The generated electric charge is used to provide power to the sound wave generator 106.

[0027] In this solution, the sound wave generator 106 can be freely selected by those skilled in the art in different application environments to emit sound signals, such as playing sound signals of bait organisms (e.g., the feeding sound of krill groups at 20-50kHz), or sound signals to drive fish, selected according to the target fish species (Salmonidae: 1-3kHz, Cyprinidae: 0.3-1kHz).

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
