Description

Technical Field

[0001] This utility model relates to the field of artificial lure technology, specifically to a biomimetic artificial lure with a noise device. Background Technology

[0002] Traditional biomimetic lures have significant limitations in terms of dynamic simulation effects and fish-attracting methods: 1. Static biomimetic structures struggle to simulate the real movement patterns of organisms, such as the leg joint movements and swimming postures of a frog; 2. Sound-based fish-attracting devices mostly employ a single mechanical sound-generating structure, resulting in monotonous tones and unadjustable sound wave frequencies; 3. Bait storage units generally use a closed design, preventing atomized release and immediate replenishment. Especially in night fishing scenarios, the lack of combined fish-attracting methods (visual dynamics + sound stimulation + chemical attraction) significantly reduces the efficiency of traditional lures. Therefore, there is an urgent need to develop an intelligent biomimetic lure system that integrates biological movement simulation, multimodal sound wave generation, and controllable bait release. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a biomimetic artificial lure with a noise-generating device, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a biomimetic artificial lure with a noise device, comprising a frog body, with movable frog legs connected to both sides of the frog body, a bait trough opened in the inner cavity of the frog body, the inner cavity of the bait trough being filled with bait, a mesh plate fixedly connected to the opening of the bait trough, a placement opening opened in the inner cavity of the mesh plate, a closing plate rotatably connected to the inner cavity of the placement opening, and rubber pads fixedly connected to both sides of the closing plate, with both rubber pads extending to the front of the closing plate;

[0005] A connecting rod is inserted into the inner cavity of the frog leg, and a sound-producing reed is fixedly connected to one end of the connecting rod.

[0006] As a further aspect of this invention: the frog leg is composed of multiple rotating parts connected front to back, and the end rotating part is fixed to the side of the frog leg. The frog leg can extend and sway in the water based on the swaying of the water flow, thereby effectively simulating the movement of a frog swimming, achieving a high degree of dynamic simulation effect, and thus enhancing the attractiveness of the bait to fish.

[0007] As a further embodiment of this utility model: an extension plate is fixedly connected to one side of the closed plate. By pulling the extension plate, the closed plate is moved to open and close the placement opening of the mesh plate. After opening, bait is added into the bait trough. Then, the closed plate is pushed, causing the inner rubber pad to be locked behind the placement opening. The closed plate is fixed by the two rubber pads. When the frog is used, the bait inside is atomized and enters the water to attract fish. When the frog moves, the sound-emitting reed is impacted by the water flow and vibrates continuously to produce sound, thus attracting fish.

[0008] As a further embodiment of this utility model: a fixed rod is fixedly connected to the lower part of the frog body, and a collar with three baffles on its surface is rotatably connected to the surface of the fixed rod. A sound-generating plate that coincides with the rotation trajectory of the baffles is fixedly connected to the lower part of the frog body. When the frog body moves, the water flow impacts the baffles, and the rotation of the collar causes the baffles to rotate and continuously strike the sound-generating plate to produce sound.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] Composite sound wave fish attraction: The dual-mode sound generation system (reed vibration + turbulence impact) can generate a wide frequency sound wave of 80-1200Hz, of which the 800Hz high frequency band effectively stimulates the auditory system of predatory fish, and the low frequency vibration wave propagation distance is increased by 40%.

[0011] Intelligent bait control: The micro-controlled release system, consisting of a mesh plate and a closed plate, achieves slow release of bait (release rate 2.5g / min) through a 0.5mm aperture array. Combined with the elastic sealing structure of the rubber pad, it ensures continuous atomization.

[0012] Fluid dynamics optimization: The three-wing spoiler design can trigger the rotation of the collar at a flow velocity of 0.3m / s, generating 15-20 regular impacts per minute with a sound intensity level of 65dB±3, while reducing water resistance by 23%. Attached Figure Description

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a bionic artificial bait with a noise device, including a frog body 1, frog legs 2 with movable structure connected to both sides of the frog body 1, a bait trough 5 opened in the inner cavity of the frog body 1, bait 10 filled in the inner cavity of the bait trough 5, a mesh plate 7 fixedly connected to the opening of the bait trough 5, a placement port 6 opened in the inner cavity of the mesh plate 7, a sealing plate 8 rotatably connected to the inner cavity of the placement port 6, rubber pads 9 fixedly connected to both sides of the sealing plate 8, and both rubber pads 9 extending to the front of the sealing plate 8;

[0020] A connecting rod 3 is inserted into the inner cavity of the frog leg 2, and a sound-producing reed 4 is fixedly connected to one end of the connecting rod 3.

[0021] The frog leg 2 is composed of multiple rotating parts that are connected front to back, and the end rotating part is fixed to the side of the frog leg 2. The frog leg 2 can extend and swing in the water based on the swaying of the water flow, thereby effectively simulating the movement of a frog swimming, achieving a high degree of dynamic simulation effect, and thus enhancing the lure's attractiveness to fish.

[0022] An extension plate 11 is fixedly connected to one side of the closed plate 8. By pulling the extension plate 11, the closed plate 8 is moved to open and close the placement opening 6 of the mesh plate 7. After it is opened, bait 10 is added to the bait trough 5. Then, the closed plate 8 is pushed, which causes the inner rubber pad 9 to be locked behind the placement opening 6. The closed plate 8 is fixed by the two rubber pads 9. When the frog body 1 is used, the bait 10 inside is atomized and enters the water to attract fish. When the frog body 1 moves, the sound-emitting reed 4 is impacted by the water flow and vibrates continuously to produce sound to attract fish.

[0023] A fixed rod 12 is fixedly connected to the lower part of the frog body 1. A collar 13 with three baffles on its surface is rotatably connected to the surface of the fixed rod 12. A sound-generating plate 14 that coincides with the rotation trajectory of the baffles is fixedly connected to the lower part of the frog body 1. When the frog body 1 moves, the water flow impacts the baffles, and the collar 13 rotates, causing the baffles to rotate and continuously impact the sound-generating plate 14 to produce sound.

[0024] When this utility model is in use, the motion simulation system works as follows: when the artificial bait is dragged at a speed of 0.5-1.2 m / s, the water flow impacts the frog leg connecting rod, and a compound swing is generated through multiple sets of hinge joints (adjacent rotation angle 15°±3), in which the deflection torque of the end rotating part reaches 0.12 N·m, realizing a biological-like motion trajectory.

[0025] Sound wave generating system:

[0026] Reed vibration module: The 304 stainless steel reed (0.2mm thick) at the end of the connecting rod generates a resonant frequency of 800±50Hz when the water flow velocity is ≥0.4m / s;

[0027] Impact sound generation module: The collar (surface Ni-P coating) rotates at 12 rpm under hydrodynamic force, and the three-wing spoiler alternately impacts the phosphor bronze sound generation plate (thickness 0.8 mm) to generate a pulse sound wave with a main frequency of 120 Hz.

[0028] Bait release system:

[0029] Opening phase: Apply a 5N pulling force to the extension plate, causing the closing plate to rotate 60° and open the placement opening, allowing the bait filling volume to reach 15cm³. 3 ;

[0030] Closure phase: The rubber gasket (Shore hardness 65±5) generates a contact pressure of 0.3MPa to achieve dynamic sealing;

[0031] Atomization process: Under the action of fluid shear force, the perforated plate (pore size Φ0.6±0.05mm) causes the bait to form atomized particles with a particle size of 50-150μm.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
