Description

Technical Field

[0001] The utility model relates to the technical field of artificial fish reefs, in particular to an artificial fish reef based on natural bait. Background Art

[0002] With the continued construction of hydropower stations, reservoirs, and water diversion projects, the hydrological conditions and ecological environment of natural rivers have undergone profound changes. These projects have led to channel blockage, channelization, and food chain disruption, impacting fish reproduction and survival. Artificial reefs, as an effective measure to protect fish resources and aquatic ecosystems, provide fish with a place to feed, grow, develop, and reproduce.

[0003] Traditional artificial reefs utilize fixed structures, lacking the ability to adapt to reservoir conditions and thus failing to effectively meet the diverse habitat needs of fish. Traditional artificial reefs lack specialized bait delivery equipment and rely primarily on regular manual feeding. However, freshwater artificial reefs are often located in Class II or Class III water function areas, where bait delivery is prohibited, making them ineffective in meeting the growth needs of larvae and juveniles.

[0004] The above information disclosed in the background technology section is only used to enhance understanding of the background of the present invention and therefore may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

The insect trap 33 is mounted on the floating platform frame 11 and attracts and kills surrounding insects flying toward the light source, releasing them into the water below the floating platform frame 11 at an appropriate time.

[0068] In one embodiment, an artificial fish reef based on natural bait includes a floating platform 1, a fish reef assembly 2, and a bait assembly 3. The floating platform 1 includes a floating platform frame 11 and a tension adjustment device 12. The fish reef assembly 2 includes an enclosed reef 21, a frame reef 22, and an upwelling reef 23. The bait assembly 3 includes a photovoltaic panel 31, an electrical device 32, and an insect trap 33. The floating platform frame 11 is a square frame 3 m long and 3 m wide composed of aluminum alloy square tubes. The cross-section of the aluminum alloy square tubes is square with a side length of 20 cm, and buoys are installed on all four sides. Tension adjustment devices 12 are provided at the four corners of the floating platform frame 11. The tension adjustment device 12 is a complete set of equipment, fixed to the floating platform frame 11, and can be connected to the fish reef assembly 2 by a cable. The tension adjustment device 23 is used to adjust the tightness of the cable to adapt to different water level changes, ensuring that the floating platform 1 and the fish reef assembly 2 connected thereto are always in a suitable state.

[0069] Enclosed reef 21 is a reinforced concrete cube, 6 meters long, 6 meters wide, and 3 meters high, with a concrete thickness of 20 cm. Enclosed reef 21 is sealed on all sides, with a 3-meter-long, 3-meter-wide square opening on the top for mounting frame reef 22, which is embedded within the square opening. Several small holes, ranging in diameter from 10 cm to 30 cm, are randomly located on the sides for fish entry and exit. Frame reef 22 is a fiberglass reinforced plastic (FRP) cube with a frame structure, 3 meters long, 3 meters wide, and 6 meters high, with a thickness of 20 cm.

[0070] The frame reef 22 is embedded in the square opening on the top surface of the enclosed reef 21, with its lower half located within the enclosed reef 21. Each side of the frame reef 22 is hollowed out, and guide rails are located on the inside of its four vertical sides for mounting the upwelling reef 23. A retaining structure is installed on the top of the frame reef 22, allowing the upwelling reef 23 to slide vertically within the frame reef 22.

[0071] Upwelling reef 23 is a four-sided pyramidal structure made of fiberglass, measuring 2.3 meters long, 2.3 meters wide, and 3 meters high. Pulleys are installed on the four vertical sides of upwelling reef 23 and are mounted within guide rails on the four vertical sides of frame-type reef 22. Three small holes, ranging in diameter from 10 to 30 cm, are provided on each side of upwelling reef 23 for fish entry and exit. The structure of upwelling reef 23 generates an upwelling effect, enabling high upwelling heights and flows.

[0072] The photovoltaic panel 31 is a complete set of equipment that converts solar energy into electrical energy. A triangular bracket is provided at the bottom of the photovoltaic panel 31 for adjusting the appropriate angle. The photovoltaic panel 31 is mounted on the floating platform frame 11. The electrical equipment 32 is a complete set of equipment and is mounted on the floating platform frame 11. The electrical equipment 32 is electrically connected to the photovoltaic panel 31 and the insect traps 33, and has functions such as power transmission and energy storage, providing electrical energy for the insect traps 33. The insect traps 33 are a complete set of equipment, with four insect traps 33 mounted on the floating platform frame 11. The insect traps 33 emit ultraviolet light, attracting surrounding insects to fly toward the light source, and kill any approaching insects with an electrified metal mesh. The killed insects are stored in the insect traps 33 and released into the water below the floating platform frame 11 when the reservoir is filled with water.

[0073] When using this artificial reef based on natural bait, the reef assembly 2 is placed at the bottom of a river with suitable flow, hard bottom, and low sediment accumulation, based on the fish reproduction needs of the river section. Bait assemblies 3 of appropriate wavelength and sufficient quantity are installed on the floating platform 1, based on the feeding needs of the fish in the river section. The floating platform 1 is transported to the top of the reef assembly 2 and connected via ropes. When the reservoir is filled with water, the water level rises, and the floating platform 1 rises with the water level, lifting the upwelling reef 23 upward via the ropes. The upwelling reef 23 can form an upwelling through its own structure, changing the speed and direction of the surrounding flow, accelerating water circulation. At the same time, the insect trap 33 releases bait, alleviating the obstruction of bait circulation caused by the reservoir filling. When the reservoir is released, the water level drops, and the floating platform 1 drops with the water level. The upwelling reef 23 descends along the track due to its own weight, and the speed and direction of the nearby water flow return to their natural state.

[0074] When the reservoir water level variation is different from the distance of variation of the upwelling reef 23 , the tension regulating device 12 can be used to adjust the rising and falling amplitudes of the upwelling reef 23 .

[0075] Finally, it should be noted that the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of this application.

[0076] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
