[0031] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model provides a technical solution for a fish behavior regulation mesh device based on shape memory alloy and acoustic-optical induction: it includes multiple sets of intelligent deformable mesh grates 1, each consisting of nickel-titanium shape memory alloy mesh sheets 101 hinged to a support frame 104. The mesh sheets 101 deform under water temperature changes to adjust the mesh size, thus adapting to the needs of different seasons and fish growth stages. The support frame 104 is a lightweight aluminum alloy profile with an "I"-shaped cross-section, and springs 102 are installed at the four corners. The ends of the springs are connected to the nickel-titanium shape memory alloy mesh sheets 101 to prevent excessive deformation of the mesh sheets. A 5cm expansion joint is reserved between adjacent intelligent deformable mesh grates to accommodate water flow impact.

[0033] Nickel-titanium shape memory alloy mesh 101 is woven into a diamond-shaped mesh, and its deformation is triggered by water temperature (response temperature range: 15-30℃), with a deformation freedom of ±30°.

[0034] Low temperature (<20℃): Tighten the net to shrink the mesh size to 2cm×2cm, restricting the passage of large fish and protecting the spawning area; when the water temperature is <15℃, the mechanical limiter forcibly locks the mesh size to 2cm×2cm.

[0035] High temperature (>25℃): The mesh openings expand to 8cm×8cm, allowing adult fish to migrate and promoting energy flow. When the water temperature is >30℃, the mechanical limiter forcibly locks the mesh size to 8cm×8cm.

[0036] The acoustic-optical induction component 4 includes an underwater speaker array and an LED flexible light strip 401. The underwater speaker array is arranged at 5m intervals, with a frequency range of 100-800Hz, and is encapsulated in a pressure-resistant stainless steel housing. The LED flexible light strip 401 is laid along the mesh and contains blue (450nm±10nm), green (520nm±10nm), and red (620nm±10nm) tri-color LEDs. Its surface is covered with an ultra-white glass cover with a light transmittance of >90%, and it is used to guide fish behavior through sound waves and spectral signals.

[0037] The energy control component 2 includes a solar photovoltaic panel 201, a waterproof main control box 202, a buoy 203, and a lithium battery. The solar photovoltaic panel 201 has a peak power of ≥100W. The waterproof main control box 202 integrates an STM32 controller and a 4G communication module, connects to the acoustic and optical components via armored cables, and is equipped with a 48Ah lithium battery to ensure continuous operation for ≥72 hours in cloudy or rainy weather.

[0038] Anchoring assembly 3 includes a nylon cable 301, a gravity anchor 302, and a helical ground stake 303. The gravity anchor 302 is a concrete counterweight with a spacing of 10m; the helical ground stake 303 is made of 304 stainless steel, with a diameter of 80mm, a burial depth of 1.5m, and a pull-out force ≥5kN, suitable for soft mud or high-velocity environments. The design of anchoring assembly 3 fully considers different water conditions, ensuring stable fixation of the device in various environments. Specifically, the gravity anchor 302 and the helical ground stake 303 can be used individually or in combination.

[0039] Artificial aquatic plants 103 are suspended on the surface of the intelligent deformable mesh, with 3-5 bundles fixed every 20cm and a length of 30-50cm, simulating the shape of natural aquatic plants and further simulating the natural ecological environment, which helps to promote the healthy growth of fish and maintain the ecological balance of the aquatic area.

[0040] The support frame 104 is treated with micro-arc oxidation to form a 10μm ceramic layer, and the connectors are made of 316L stainless steel, which is resistant to salt spray corrosion for more than 3000 hours, ensuring the durability and reliability of the device.

[0041] The fish behavior regulation netting device of this invention achieves effective regulation of fish behavior through the coordinated work of intelligent deformation netting, acoustic and optical induction components, energy control components, and anchoring components. At the same time, it reduces the stress response of fish and the impact on the environment, and improves the stability and reliability of the device.

[0042] The working principle and usage process of this utility model are as follows: The fish behavior control mesh device of this utility model is deployed in the target water area. Solar energy is collected by the solar photovoltaic panel 201 and converted into electrical energy, which is stored in the lithium battery to provide a continuous power supply for the entire device. The STM32 controller in the waterproof main control box 202 controls the working state of the acoustic and light induction component 4 according to the preset program and the remote commands received by the 4G communication module.

[0043] When the water temperature changes, the nickel-titanium shape memory alloy mesh 101 deforms according to a preset temperature range, automatically adjusting the mesh size. For example, in cold seasons, the mesh shrinks to restrict the passage of large fish and protect the spawning area; while in hot seasons, the mesh expands to allow adult fish to migrate and promote energy flow.

[0044] Meanwhile, the underwater speaker array of the acoustic-optical induction component 4 emits sound waves of a specific frequency, and the LED flexible light strip 401 emits blue, green, and red spectral signals. These sound waves and spectral signals work together to guide the fish to move along a predetermined path, reducing the stress response caused by physical barriers.

[0045] The anchoring assembly 3 ensures that the device can be stably fixed in various water conditions. The combination of gravity anchor 302 and helical pile 303 improves the pull-out resistance and stability of the device.

[0046] In addition, the artificial aquatic plants 103 suspended on the surface of the intelligent deformable mesh simulate the natural ecological environment, providing a place for fish to inhabit and forage, which helps to promote the healthy growth of fish and maintain the ecological balance of the water.

[0047] Throughout the entire process, the fish behavior regulation net device of this utility model, through intelligent sensing, precise regulation and eco-friendly design, has achieved effective regulation of fish behavior, improved the utilization efficiency of aquatic ecological resources and promoted the maintenance of aquatic ecological balance.
