Abstract
Description
Technical Field
[0001] This invention relates to the field of artificial underwater construction technology, and in particular to a multi-layer mesh curtain installation device. Background Technology
[0002] Underwater noise is inevitably generated during the construction of offshore wind farms and the construction of foundations and bridge supports for rivers, ports, and wharves. This underwater noise has irreversible adverse effects on aquatic animals. Sound waves attenuate more slowly in water than in air, and their impact distance is longer. Furthermore, the assessment requirements for the impact of underwater noise on aquatic animals are becoming increasingly stringent due to the ongoing underwater construction work, making the reduction of underwater noise propagation urgent. Research has shown 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. However, due to the complex underwater construction environment, the number of noise reduction net layers needs to be adjusted according to the construction situation to avoid excessive noise reduction netting affecting surrounding organisms. Simultaneously, to ensure the noise reduction effect, the distribution range and location of the noise reduction nets also need to be adjusted according to the construction location. 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 multi-layer mesh curtain installation device, which can drive the magnetic metal plate to move through electromagnetic induction, drive the sliding parts to move synchronously, and trigger the steering part when the first sliding block moves to the end, so that the telescopic part turns and extends into the fixed chamber, so that the multi-layer mesh curtain is fixed twice. This ensures that when the multi-layer noise reduction net is installed to form a multi-layer mesh curtain, it will not fall off at will, nor will it become entangled and stuck together, resulting in a deterioration of 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.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multi-layer mesh curtain installation device, which includes an installation unit, including 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.
[0006] As a preferred embodiment of the multi-layer mesh curtain installation device of the present invention, the magnetic suction component includes a power source disposed on the outside of the partition component, 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.
[0007] As a preferred embodiment of the multi-layer mesh curtain installation device of the present invention, the adjustment component includes a magnetic metal plate disposed on one side of the electromagnetic coil, a fixing plate disposed on one side of the magnetic metal plate, a reset spring whose two ends are fixedly connected to the magnetic metal plate and the fixing plate 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.
[0008] 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.
[0009] As a preferred embodiment of the multi-layer mesh curtain installation device of the present invention, the telescopic component 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.
[0010] 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;
[0011] 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.
[0012] As a preferred embodiment of the multi-layer mesh curtain installation device of the present invention, 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.
[0013] As a preferred embodiment of the multi-layer mesh curtain installation device of the present invention, the partition component includes a support plate fixedly connected to the power block, a top plate fixedly connected to the support plate, a plurality of limiting plates inserted into the top plate, and a groove plate inserted into the limiting plates.
[0014] As a preferred embodiment of the multi-layer mesh curtain installation device of the present invention, the connecting component includes a mounting base fixedly connected to the top plate, a locking claw hinged to the mounting base, and a fixing pin hinged to the locking claw.
[0015] As a preferred embodiment of the multi-layer mesh curtain installation device of 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 mesh 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, so that the installation of the noise reduction mesh is more stable.
[0016] As a preferred embodiment of the multi-layer mesh curtain installation device of the present invention, 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 parts at equidistant positions, so that when moved by the magnetic metal plate, they stop at fixed positions in sequence and are finally equidistantly distributed on one side of the limiting plate.
[0017] As a preferred embodiment of the multi-layer mesh curtain installation device of the present invention, the steering component drives the sliding component to rotate 90 degrees when the first sliding block slides to the tail end with the magnetic metal plate, 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 mesh.
[0018] The beneficial effects of this invention are as follows: This invention uses electromagnetic induction to drive the magnetic metal plate to move, which in turn drives the sliding component to move synchronously. When the first sliding block moves to the end, it triggers the steering component, causing the telescopic component to turn and extend into the fixed chamber. 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, nor will it 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.

Therefore, the invention is not limited to the specific embodiments disclosed below.
[0028] 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.
[0029] Example 1
[0030] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a multi-layer mesh curtain installation device, which can drive the magnetic metal plate 102a to move through electromagnetic induction, so that the sliding member 102d triggers the turning 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] Furthermore, the telescopic assembly 103 includes a steering member 103a disposed at the bottom of the slide rail 102f, a fixed housing 103b disposed on one side of the sliding member 102d, and a telescopic member 103c disposed inside the fixed housing 103b.
[0036] The steering component 103a includes a rotating shaft 103a-1 that passes through and is disposed inside the fixed housing 103b, 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. The steering rail 103a-3 is provided with a push plate at its end, and the steering rail 103a-3 can only move in a direction perpendicular to the slide rail 102f.
[0037] The telescopic component 103c includes a push spring 103c-1 disposed inside the fixed housing 103b, a sliding sleeve shaft 103c-2 sleeved with the fixed housing 103b, 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. The fixed housing 103b, located above the fixed block 102d-2, will not rotate.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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. The steering component 103a drives the fixed housing 103b to rotate counterclockwise by 90 degrees. When the fixed housing 103b 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 103b, pushing the pressure of the spring 103c-1 to be released, and pushing the sliding sleeve shaft 103c-2 to slide outward. 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 through meshing. 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.
[0042] 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.
[0043] 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.
[0044] It should be noted that, Figure 4In the partial structure of the steering component shown, the steering track 103a-3 has a groove on the inner side, and the steering rod 103a-2 is located on the lower side of the steering track 103a-3. The groove on the inner side of the steering track 103a-3 should be sleeved on the outer side of the steering rod 103a-2. For ease of display, the attached figure only shows a schematic diagram of the two structures in a separated state, and the assembly relationship described therein does not exist.
[0045] 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. This creates a magnetic field 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. The first sliding block 102d-1 drives the second sliding block 102d-3 to move synchronously along the slide rail 102f via the synchronous belt 102e. The second sliding blocks 102d-3 are evenly distributed on the outside of the slide rail 102f according to the limit of the synchronous belt 102e. When the first sliding block 102d-1 slides to its end, it actuates the 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 103b to rotate counterclockwise, causing the fixed housing 103b to rotate... When the fixed housing 103b moves 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 103b 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 to rotate along the belt. Moving forward, the limiting block 103c-5 drives the limiting shaft 103c-8 to move 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, the compression state is released, and the self-locking pin 104c falls and locks into the limiting shaft 103c-8 under the action of the self-locking spring 104d, locking the limiting shaft 103c-8 and the fixed chamber 104a, thus completing the fixation of the entire device.
[0046] 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.
[0047] 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.
[0048] 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.
