Description

Technical Field

[0001] This invention relates to the field of man-made underwater construction technology, and in particular to a noise reduction system for reducing the impact of man-made underwater noise on aquatic organisms. Background Technology

[0002] Underwater noise is unavoidable in the construction of offshore wind farms and infrastructure such as rivers, ports, and wharves, causing irreversible adverse effects on aquatic animals. Because sound waves travel slower and over longer distances in water, reducing underwater noise propagation is crucial. Research shows that sound speed and propagation range are significantly reduced when it encounters gas in water. Therefore, installing multi-layered noise reduction nets to form a multi-layered mesh curtain, evenly attaching air bubbles discharged from air ducts to weaken underwater noise layer by layer, is a practical method. When installing the multi-layered mesh curtain, the number of layers needs to be adjusted according to the construction situation to ensure the noise reduction effect. Simultaneously, to minimize the impact on surrounding organisms, the distribution and location of the noise reduction nets need to be adjusted according to the construction site, and the bubble emission density needs to be adjusted according to the required noise reduction capacity to avoid wasting energy. Summary of the Invention

[0003] In view of the problems existing in the above or prior art, the present invention is proposed.

[0004] Therefore, the purpose of this invention is to provide a noise reduction system that reduces the impact of man-made underwater noise on aquatic organisms, which can reduce the noise impact of underwater construction on aquatic organisms by uniformly interfering with the transmission of sound waves through bubble interference.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a noise reduction system for reducing the impact of man-made underwater noise on aquatic organisms, comprising a noise reduction system, including an installation module, an adsorption module connected to the installation module, a noise reduction module connected to the installation module, a detection module connected to the noise reduction module, and a control module connected to the detection module.

[0006] As a preferred embodiment of the noise reduction system of the present invention for reducing the impact of man-made underwater noise on aquatic organisms, the noise reduction system further includes an exhaust module connected to the noise reduction module and a sensing module connected to the adsorption module.

[0007] As a preferred embodiment of the noise reduction system for reducing the impact of man-made underwater noise on aquatic organisms according to the present invention, the adsorption module includes a fixed outer shell fixedly connected to the installation module, a fixed rack fixedly connected to the fixed outer shell, a transmission gear meshing with the fixed rack, a movable rack meshing with the transmission gear, a telescopic rod fixedly connected to the movable rack, and a flexible suction cup fixedly connected to the telescopic rod.

[0008] As a preferred embodiment of the noise reduction system of the present invention for reducing the impact of man-made underwater noise on aquatic organisms, the noise reduction module includes a mesh noise reduction curtain; the detection module includes a sound wave detector; the control module includes a control terminal; the exhaust module includes a bubble emitter; and the sensing module includes an infrared detector.

[0009] As a preferred embodiment of the noise reduction system for reducing the impact of man-made underwater noise on aquatic organisms according to the present invention, the detection module can adjust the density of the bubbles emitted by the exhaust module according to the noise level generated by underwater construction. When the noise generated by construction is large, the detection module feeds back the sound wave data to the control module, and the control module controls the exhaust module to increase the bubble emission density and increase the noise reduction effect. When the noise generated by construction is small, the detection module feeds back the sound wave data to the control module, and the control module controls the exhaust module to decrease the bubble emission density and decrease the noise reduction effect, so as to achieve targeted noise reduction.

[0010] As a preferred embodiment of the noise reduction system for reducing the impact of man-made underwater noise on aquatic organisms according to the present invention, the exhaust module is disposed on one side of the installation module and is attached to one end of the noise reduction module. It is controlled by the control module to adjust the density of the exhaust bubbles, ensuring precise noise reduction while accurately discharging the bubbles into the noise reduction module, so that the bubbles are evenly attached between the mesh noise reduction curtains to ensure uniform noise reduction.

[0011] As a preferred embodiment of the noise reduction system for reducing the impact of man-made underwater noise on aquatic organisms according to the present invention, the sensing module is set on one side of the adsorption module, so that the distance to the adsorption part is detected before the adsorption module adsorbs to the construction position, and the detection data is fed back to the control module. The control module performs difference calculation on the detection data and the pre-stored data. When the difference is zero, the control module controls the adsorption module to adsorb, ensuring that the adsorption module can accurately adsorb and avoiding the installation module from falling off during the construction process.

[0012] As a preferred embodiment of the noise reduction system for reducing the impact of man-made underwater noise on aquatic organisms according to the present invention, the installation module includes a magnetic suction component, an adjustment component disposed on one side of the magnetic suction component, a telescopic component disposed on one side of the adjustment component, a fixing component disposed at one end of the telescopic component, a partition component fixedly connected to the magnetic suction component and the fixing component respectively, and a connecting component disposed on the outside of the partition component.

[0013] The magnetic attraction assembly includes a power source disposed on the outside of the separator assembly, an electromagnetic coil fixedly connected to one end of the power source, and an energized iron core disposed on the inside of the electromagnetic coil.

[0014] The pitch adjustment assembly includes a magnetic metal plate disposed on one side of the electromagnetic coil, a fixed plate disposed on one side of the magnetic metal plate, a reset spring fixedly connected to the magnetic metal plate and the fixed plate at both ends respectively, a sliding member fixedly connected to the magnetic metal plate, a synchronous belt passing through the inner side of the sliding member, and a slide rail sleeved with the sliding member.

[0015] The sliding component includes a first sliding block fixedly connected to the magnetic metal plate, a fixed block fixedly connected to the fixed plate, and a set of second sliding blocks disposed between the first sliding block and the fixed plate;

[0016] The telescopic assembly includes a steering component disposed at the bottom of the slide rail, a fixed housing disposed on one side of the sliding component, and a telescopic component disposed inside the fixed housing;

[0017] The steering component includes a rotating shaft that passes through and is disposed inside the fixed housing, a steering rod that is fixedly connected to the rotating shaft, and a steering rail that is slidably connected to the steering rod;

[0018] The telescopic component includes a push spring disposed inside the fixed housing, a sliding sleeve shaft sleeved with the fixed housing, a pulley fixedly connected to the sliding sleeve shaft, a transmission belt sleeved with the pulley, a limiting block fixedly connected to the transmission belt, a sliding gear fixedly connected to the pulley, a sliding rack meshing with the sliding gear, and a limiting shaft fixedly connected to the limiting block.

[0019] As a preferred embodiment of the noise reduction system of the present invention for reducing the impact of man-made underwater noise on aquatic organisms, the fixing component includes a fixing chamber disposed at one end of the limiting shaft, a sliding chamber fixedly connected to the outside of the fixing chamber, a self-locking pin disposed on the inside of the sliding chamber, a self-locking spring disposed on the outside of the self-locking pin, and an unlocking rod hinged to the top of the self-locking pin.

[0020] The partition assembly includes a support plate fixedly connected to the power block, a top plate fixedly connected to the support plate, several limiting plates inserted into the top plate, and a slotted plate inserted into the limiting plates.

[0021] The connecting assembly includes a mounting base fixedly connected to the top plate, a locking claw hinged to the mounting base, and a retaining pin hinged to the locking claw.

[0022] As a preferred embodiment of the noise reduction system for reducing the impact of man-made underwater noise on aquatic organisms according to the present invention, the number of the second sliding blocks can be increased or decreased as needed. When there are many layers of noise reduction net installed, the number of the second sliding blocks is increased, and the number of telescopic components is increased according to the number of the second sliding blocks to make the installation of the noise reduction net more stable. The synchronous belt passes through the inner side of the first sliding block, the second sliding block and the fixed block respectively, and is fixedly connected to all sliding components at equidistant positions, so that when the magnetic metal plate moves, they stop at fixed positions in sequence and are finally distributed equidistantly on one side of the limiting plate. When the first sliding block slides to the tail end with the magnetic metal plate, the steering device drives the sliding component to rotate 90 degrees, so that the telescopic component changes from the direction parallel to the slide rail to the direction perpendicular to the slide rail. At the same time, the compressive force on the spring disappears, the spring returns to its original length, and the telescopic component extends along the direction perpendicular to the slide rail to fix the noise reduction net.

[0023] The beneficial effects of this invention are as follows: This invention enables the installation module to function better by combining the detection module and the adsorption module. It allows the noise reduction module to precisely adjust the noise reduction intensity according to the noise intensity of underwater construction, saving energy and making energy rationally distributed. It can also accurately adsorb the target object, making the entire noise reduction system stable and not easy to slip during operation. It can better adapt to complex underwater construction environments and minimize the adverse effects of underwater construction noise on aquatic organisms. Attached Figure Description

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a noise reduction system M for reducing the impact of man-made underwater noise on aquatic organisms. The system can reduce the noise impact of underwater construction on aquatic organisms by using uniform bubble interference to conduct sound waves.

[0039] Specifically, the noise reduction system M includes an installation module 100, an adsorption module 200 connected to the installation module 100, a noise reduction module 300 connected to the installation module 100, a detection module 400 connected to the noise reduction module 300, and a control module 500 connected to the detection module 400.

[0040] Furthermore, the noise reduction system M also includes an exhaust module 600 connected to the noise reduction module 300, and a sensing module 700 connected to the adsorption module 200.

[0041] Furthermore, the adsorption module 200 includes a fixed housing 201 fixedly connected to the mounting module 100, a fixed rack 202 fixedly connected to the fixed housing 201, a transmission gear 203 meshing with the fixed rack 202, a movable rack 204 meshing with the transmission gear 203, a telescopic rod 205 fixedly connected to the movable rack 204, and a flexible suction cup 206 fixedly connected to the telescopic rod 205.

[0042] Furthermore, the noise reduction module 300 includes a mesh noise reduction curtain 301; the detection module 400 includes a sound wave detector 401; the control module 500 includes a control terminal 501; the exhaust module 600 includes a bubble emitter 601; and the sensing module 700 includes an infrared detector 701.

[0043] Furthermore, the detection module 400 can adjust the density of the bubbles emitted by the exhaust module 600 according to the noise level generated by underwater construction. When the noise generated by construction is large, the detection module 400 feeds back the sound wave data to the control module 500, and the control module 500 controls the exhaust module 600 to increase the bubble emission density and increase the noise reduction effect. When the noise generated by construction is small, the detection module 400 feeds back the sound wave data to the control module 500, and the control module 500 controls the exhaust module to decrease the bubble emission density and decrease the noise reduction effect, so as to achieve targeted noise reduction.

[0044] Furthermore, the exhaust module 600 is located on one side of the mounting module 100 and is attached to one end of the noise reduction module 300. It is controlled by the control module 500 to adjust the density of the exhaust bubbles, ensuring precise noise reduction while accurately discharging the bubbles into the noise reduction module 300, so that the bubbles are evenly attached between the mesh noise reduction curtains 301 to ensure uniform noise reduction.

[0045] Furthermore, the sensing module 700 is located on one side of the adsorption module 200, so that before the adsorption module 200 adsorbs to the construction position, it can detect the distance to the adsorption part and feed back the detection data to the control module 500. The control module 500 performs a difference calculation on the detection data and the pre-stored data. When the difference is zero, the control module 500 controls the adsorption module 200 to adsorb, ensuring that the adsorption module 200 can accurately adsorb and preventing the installation module 100 from falling off during the construction process.

[0046] It should be noted that all modules and connection methods in this embodiment can adopt existing technologies. For example, the control module 500 includes a control terminal 501. The control terminal 501 can control each module and process the feedback data from each module. The flexible suction cup 206 can adjust its own angle according to the adsorption direction to adapt to various adsorption environments.

[0047] The working principle of this system is as follows: During installation, the control module 500 controls the movement of the adsorption module 200, while the sensing module 700 calculates the distance to the construction site. The sensing module 700 feeds back the calculated data to the control module 500, which calculates the difference between the calculated data and a preset value. When the difference is zero, the control module 500 controls the adsorption module 200 to adsorb the material. When installation is complete, the detection module 400 judges the noise generated by the underwater construction. If the noise data is greater than the standard value stored in the control module 500, the control module 500 controls the exhaust module 600 to increase the density of the emitted bubbles, so that more bubbles adhere between the noise reduction modules 300. If the noise data is less than the standard value stored in the control module 500, the control module 500 controls the exhaust module 600 to decrease the density of the emitted bubbles, so that fewer bubbles adhere between the noise reduction modules 300. This achieves targeted noise reduction, reduces energy consumption, avoids energy waste, and achieves precise noise reduction.

[0048] In summary, the present invention enables the installation module 100 to function better by cooperating with the detection module 400 and the adsorption module 200, allowing the noise reduction module 300 to precisely adjust the noise reduction intensity according to the underwater construction noise intensity, saving energy and making energy rationally allocated. It can also accurately adsorb the target object, making the entire noise reduction system M stable and not easy to slip during operation, better adapting to complex underwater construction environments, and minimizing the adverse effects of underwater construction noise on aquatic organisms.

[0049] Example 2

[0050] Reference Figures 4-9 This is the second embodiment of the present invention. This embodiment provides a noise reduction system M to reduce the impact of man-made underwater noise on aquatic organisms. It can drive the magnetic metal plate 102a to move through electromagnetic induction, so that the sliding member 102d triggers the steering member 103a while being equidistantly dispersed, and the telescopic member 103c extends while turning, thus completing the two fixation of the multi-layer mesh curtain.

[0051] Specifically, the installation unit 100 includes a magnetic suction assembly 101, an adjustment assembly 102 disposed on one side of the magnetic suction assembly 101, a telescopic assembly 103 disposed on one side of the adjustment assembly 102, a fixing assembly 104 disposed at one end of the telescopic assembly 103, a partition assembly 105 fixedly connected to the magnetic suction assembly 101 and the fixing assembly 104 respectively, and a connecting assembly 106 disposed on the outside of the partition assembly 105.

[0052] Furthermore, the magnetic attraction assembly 101 includes a power supply 101a disposed outside the separation assembly 105, an electromagnetic coil 101b fixedly connected to one end of the power supply 101a, and an energized iron core 101c disposed inside the electromagnetic coil 101b.

[0053] Furthermore, the pitch adjustment assembly 102 includes a magnetic metal plate 102a disposed on one side of the electromagnetic coil 101b, a fixing plate 102b disposed on one side of the magnetic metal plate 102a, a reset spring 102c whose two ends are fixedly connected to the magnetic metal plate 102a and the fixing plate 102b respectively, a sliding member 102d fixedly connected to the magnetic metal plate 102a, a timing belt 102e passing through the inner side of the sliding member 102d, and a slide rail 102f sleeved with the sliding member 102d. The timing belt 102e is made of flexible material. The sliding member 102d is fixedly connected to the timing belt 102e at intervals as needed to limit the position of the sliding member 102d.

[0054] The sliding member 102d includes a first sliding block 102d-1 fixedly connected to the magnetic metal plate 102a, a fixed block 102d-2 fixedly connected to the fixed plate 102b, and a set of second sliding blocks 102d-3 disposed between the first sliding block 102d-1 and the fixed plate 102b. The distance between the first sliding block 102d-1, the fixed block 102d-2, and the second sliding block 102d-3 is equal. The fixed block 102d-2 is fixed to the surface of the fixed plate 102b. The first sliding block 102d-1 slides to the end with the magnetic metal plate 102a. The number of second sliding blocks 102d-3 is set as needed (not less than two), and they are evenly distributed between the fixed block 102d-2 and the first sliding block 102d-1 during the sliding process.

[0055] Furthermore, the telescopic assembly 103 includes a steering member 103a disposed at the bottom of the slide rail 102f, a fixed housing 201103b disposed on one side of the sliding member 102d, and a telescopic member 103c disposed inside the fixed housing 201103b.

[0056] The steering component 103a includes a rotating shaft 103a-1 that passes through and is disposed inside the fixed housing 201103b, a steering rod 103a-2 that is fixedly connected to the rotating shaft 103a-1, and a steering rail 103a-3 that is slidably connected to the steering rod 103a-2, wherein a push plate is provided at the end of the steering rail 103a-3;

[0057] The telescopic component 103c includes a push spring 103c-1 disposed inside the fixed housing 201103b, a sliding sleeve shaft 103c-2 sleeved with the fixed housing 201103b, a pulley 103c-3 fixedly connected to the sliding sleeve shaft 103c-2, a transmission belt 103c-4 sleeved with the pulley 103c-3, a limiting block 103c-5 fixedly connected to the transmission belt 103c-4, a sliding gear 103c-6 fixedly connected to the pulley 103c-3, a sliding rack 103c-7 meshing with the sliding gear 103c-6, and a limiting shaft 103c-8 fixedly connected to the limiting block 103c-5.

[0058] Furthermore, the fixing assembly 104 includes a fixing chamber 104a disposed at one end of the limiting shaft 103c-8, a sliding chamber 104b fixedly connected to the outside of the fixing chamber 104a, a self-locking pin 104c disposed inside the sliding chamber 104b, a self-locking spring 104d disposed outside the self-locking pin 104c, and an unlocking rod 104e hinged to the top of the self-locking pin 104c.

[0059] It should be noted that both the limiting shaft 103c-8 and the fixed chamber 104a have through holes adapted to the self-locking pin 104c. When the limiting shaft 103c-8 enters the fixed chamber 104a, the through hole of the limiting shaft 103c-8 is aligned with the through hole of the fixed chamber 104a, and the self-locking pin 104c falls under the action of the self-locking spring 104d, locking the limiting shaft 103c-8 in the fixed chamber 104a.

[0060] Furthermore, the separating component 105 includes a support plate 105a fixedly connected to the power supply 101a block, a top plate 105b fixedly connected to the support plate 105a, a plurality of limiting plates 105c inserted into the top plate 105b, and a slotted plate 105d inserted into the limiting plates 105c. The top plate 105b is provided with matching slots for the limiting plates 105c and the slotted plate 105d, and the slotted plate 105d is provided with a slot for matching the limiting plates 105c. The number of limiting plates 105c is not less than five. The top of the limiting plate 105c is wider than the plate body and is used to initially fix the noise reduction mesh. The limiting plates 105c are inserted into the top plate 105b, and the slotted plates 105d are inserted into both sides of the limiting plates 105c. At the same time, the slotted plates 105d are inserted into the top plate 105b.

[0061] It should be noted that the magnetic metal plate 102a drives the first sliding block 102d-1 to slide to the end. The first sliding block 102d-1 triggers the steering component 103a, which drives the fixed housing 201103b to rotate counterclockwise by 90 degrees. When the fixed housing 201103b rotates to a position perpendicular to the slide rail 102f, the through hole of the limiting plate 105c pushes open the cover plate at the end of the fixed housing 201103b, thus releasing the pressure of the spring 103c-1. The sliding sleeve shaft 103c-2 is pushed outward, and at the same time, the sliding rack 103c-7 drives the sliding gear 103c-6 to rotate during the movement of the sliding sleeve shaft 103c-2. The sliding gear 103c-6 drives the transmission belt 103c-4 to rotate through the pulley 103c-3. The transmission belt 103c-4 drives the limiting shaft 103c-8 to move synchronously through the limiting block 103c-5, and finally enters the fixed chamber 104a.

[0062] Furthermore, the connecting assembly 106 includes a mounting base 106a fixedly connected to the top plate 105b, a locking claw 106b hinged to the mounting base 106a, and a fixing pin 106c hinged to the locking claw 106b, wherein the fixing pin 106c passes through the mounting base 106a and the locking claw 106b, ensuring that the locking claw 106b can rotate inside the mounting base 106a.

[0063] Preferably, the number of second sliding blocks 102d-3 can be increased or decreased as needed. When there are many layers of noise reduction mesh installed, the number of second sliding blocks 102d-3 is increased. At the same time, the number of telescopic components 103c is increased according to the number of second sliding blocks 102d-3, making the installation of the noise reduction mesh more stable. The synchronous belt 102e passes through the inner sides of the first sliding block, the second sliding block 102d-3, and the fixed block 102d-2, and is fixedly connected to all sliding components 102d at equidistant positions. When moved by the magnetic metal plate 102a, it stops at the fixed positions in sequence and is finally distributed equidistantly on one side of the limiting plate 105c. When the first sliding block 102d-1 slides to the end along with the magnetic metal plate 102a, the steering component 103a drives the sliding component 102d to rotate 90 degrees, causing the telescopic component 103c to turn from a direction parallel to the slide rail 102f to a direction perpendicular to the slide rail 102f. At the same time, the compressive force on the spring 103c-1 disappears, the spring 103c-1 returns to its original length, and the telescopic component 103c extends along a direction perpendicular to the slide rail 102f to fix the noise reduction net.

[0064] In use, when installing the noise reduction mesh, the operator installs the required number of limiting plates 105c on both sides of the mounting slots 105d. The slots 105d and limiting plates 105c are then inserted into the slots provided in the top plate 105b. The noise reduction mesh is then installed between the limiting plates 105c, and initially fixed through the narrow gap between the wider portions of the top of the limiting plates 105c. Next, the operator connects the power supply 101a, energizing the electromagnetic coil 101b. A magnetic field is formed inside the energized iron core 101c, attracting the magnetic metal plate 102a to move towards the energized iron core 101c. The magnetic metal plate 102a drives the first sliding block 102d-1 to move synchronously and in the same direction along the slide rail 102f. A sliding block 102d-1 drives a second sliding block 102d-3 to move synchronously along a slide rail 102f via a timing belt 102e. The second sliding blocks 102d-3 are evenly distributed on the outer side of the slide rail 102f according to the limiting position of the timing belt 102e. When the first sliding block 102d-1 slides to its end, it actuates a push plate at the end of the steering track 103a-3, causing the steering track 103a-3 to move. The steering track 103a-3 then drives the steering rod 103a-2 to move synchronously. The steering rod 103a-2 drives the moving shaft to rotate, which in turn drives the fixed housing 201103b to rotate counterclockwise, causing the fixed housing 201103b to... When the fixed housing 201103b rotates from a position parallel to the slide rail 102f to a position perpendicular to the slide rail 102f, the cover plate at the front end of the fixed housing 201103b is pushed open by the through hole of the limiting plate 105c, releasing the pressure of the spring 103c-1 and pushing the sliding sleeve shaft 103c-2 forward. At the same time, the sliding gear 103c-6 rotates along the sliding rack 103c-7 through meshing. The sliding gear 103c-6 drives the pulley 103c-3 to rotate synchronously in the same direction. The pulley 103c-3 drives the transmission belt 103c-4 to rotate. The transmission belt 103c-4 drives the limiting block 103c-5. Moving forward along the belt, the limiting block 103c-5 drives the limiting shaft 103c-8 forward into the fixed chamber 104a, allowing the telescopic component 103c to pass through the reserved hole of the noise reduction net and simultaneously complete the double-stage stroke amplification, thus fixing the noise reduction net a second time to ensure that the noise reduction net will not fall off underwater. When the limiting shaft 103c-8 enters the fixed chamber 104a, the through hole of the limiting shaft 103c-8 is aligned with the through hole of the fixed chamber 104a, the pressure of the self-locking spring 104d is released, and the compression state is released. Under the action of the self-locking spring 104d, the self-locking pin 104c falls and locks into the limiting shaft 103c-8, locking the limiting shaft 103c-8 and the fixed chamber 104a, thus completing the fixation of the entire device.

[0065] When multiple devices need to be connected in series, the operator selects the connecting component 106 as needed, inserts the mounting base 106a into one side of the top plate 105b through the slot, fixes the mounting base 106a on the other side to another top plate 105b, and clamps the locking claw 106b on one side to the locking claw 106b on the other side, thus completing the connection between the two mounting units 100. This allows the angle between the mounting units 100 to be adjusted while they are fixedly connected.

[0066] When underwater noise reduction is performed, the control terminal 501 controls the transmission gear 203 to slide outward along the fixed rack 202 through meshing. At the same time, the transmission gear 203 drives the moving rack 204 to slide outward through meshing. Meanwhile, the infrared detector 701 detects the installation position. When the difference between the data fed back by the detector and the preset data stored in the control terminal 501 is zero, the control terminal 501 controls the flexible suction cup 206 to adaptively adsorb the installation position, completing the adsorption of the installation module 100. This ensures that the position of the mesh noise reduction curtain 301 is stable during the noise reduction process and will not drift with the water waves.

[0067] When the use is finished, the staff retrieves the multi-layered mesh curtain from the water, removes the connecting assembly 106 between the top plates 105b, further rotates the unlocking lever 104e to lift the self-locking pin 104c, unlocking the limiting shaft 103c-8 from the fixing chamber 104a, pushes the limiting shaft 103c-8 back to its initial position, manually restores the cover plate on the fixing shell 103b, completely pulls the limiting shaft 103c-8 out of the preset hole in the noise reduction mesh, and further disconnects the power supply 101a, preventing the electromagnetic coil 101b from... When power is applied again, the magnetic field inside the energized iron core 101c disappears, the magnetic metal plate 102a loses its attraction, and the first slider slides back to the initial position following the reset spring 102c. At the same time, the steering component 103a releases pressure and turns back to the initial position, causing the fixed housing 103b to turn to a position parallel to the slide rail 102f. The fixed housing 103b maintains this angle and follows the slider 102d back to the initial position, further removing the noise reduction mesh from between the limiting plates 105c, thus completing the disassembly of the multi-layer mesh curtain.

[0068] In summary, this invention uses electromagnetic induction to move the magnetically attracted metal plate 102a, which in turn moves the sliding member 102d synchronously. When the first sliding block 102d-1 moves to its end, it triggers the steering member 103a, causing the telescopic member 103c to turn and extend into the fixed chamber 104a. This allows the multi-layer mesh curtain to be fixed twice, ensuring that when the multi-layer noise reduction net is installed using this device to form a multi-layer mesh curtain, it will not fall off at will or become entangled and stuck together, which would lead to a deterioration in the noise reduction effect. This ensures that the noise generated during underwater construction can be reduced efficiently and evenly, and improves the installation efficiency of the noise reduction net.
