Description

Technical Field

[0001] This application relates to the field of marine technology, and in particular to a wirelessly powered propeller-based anti-marine biological device. Background Technology

[0002] In the marine environment, ship propellers are constantly immersed in seawater, making them highly susceptible to the attachment of marine organisms. Barnacles, algae, mussels, and other organisms attached to the propeller surface significantly increase its roughness, altering hydrodynamic performance and leading to increased drag and fuel consumption.

[0003] Currently, common anti-marine organism devices use acoustic transducers to emit ultrasonic waves of specific frequencies. These waves disrupt the marine organisms' environment and physiological activities, preventing them from adhering to the propeller surface. However, because the propeller is constantly rotating, the transducer, connected to the power supply via a power cord, needs to be mounted outside the propeller shaft using a bearing structure. This mounting method creates a gap between the transducer and the propeller shaft, resulting in poor acoustic wave transmission efficiency and a weak anti-adhesion effect.

[0004] Therefore, there is a need to provide a wirelessly powered propeller-based anti-marine organism device. Utility Model Content

[0005] To address the problem that existing marine organism control devices have a weak anti-attachment effect due to a certain gap between the device and the propeller shaft during installation, this application provides a wirelessly powered propeller-based marine organism control device.

[0006] This application provides a wirelessly powered propeller-based anti-marine organism device, which adopts the following technical solution: it includes a clamping component, a transducer, and a power supply component, wherein the clamping component is clamped and fixed to the shaft of the propeller; The transducer is disposed on the clamping assembly; The power supply assembly includes a bracket, a transmitting coil, and a receiving coil. One end of the bracket is located on the inner wall of the ship, and the other end of the bracket is connected to the transmitting coil. The transmitting coil is electrically connected to the receiving coil through a magnetic field. The receiving coil is sleeved on the shaft of the propeller and can rotate with the shaft. The receiving coil is also electrically connected to the transducer.

[0007] By adopting the above technical solution, the clamping assembly can firmly install the transducer on the propeller shaft. The transmitting coil of the power supply assembly is electrically connected to the receiving coil, which is sleeved on the shaft and rotates with it, through a magnetic field, thereby supplying power to the transducer and ensuring its stable operation. This effectively disrupts the living environment and physiological activities of marine organisms, preventing them from adhering to the propeller surface. Compared with existing technologies that connect to the power supply equipment via a power line and require the transducer to be mounted outside the propeller shaft via a bearing structure, resulting in poor sound wave transmission efficiency and weak anti-adhesion effect due to gaps between the transducer and the shaft, this device avoids the gap problem, improves sound wave transmission efficiency, and enhances the anti-adhesion effect.

[0008] Specifically, the clamping assembly includes a mounting plate, a connecting strip, and connecting bolts. One side of the mounting plate has an arc-shaped surface adapted to the shaft of the propeller. The transducer is located on the other side of the mounting plate. A connecting through hole is provided on one side of the mounting plate, and the connecting strip is fitted onto the connecting strip through the connecting through hole. Both ends of the connecting strip are provided with connecting ears, and the connecting strip can be fitted onto the shaft of the propeller. The two ends of the connecting strip are screwed to the connecting bolts through the ear holes of the two connecting ears and screwed to the nuts, thus pressing the arc-shaped surface against the shaft of the propeller.

[0009] By adopting the above technical solution, the arc-shaped surface on one side of the mounting plate is adapted to the propeller shaft, so that the clamping assembly can better fit the shaft; the mounting plate is fitted onto the connecting strip through the connecting through hole, and the two ends of the connecting strip are connected to each other by connecting bolts, and the arc-shaped surface is pressed against the shaft, so that the clamping assembly is firmly clamped and fixed on the propeller shaft, ensuring that the transducer is stably installed on the clamping assembly, thereby improving the transducer's acoustic wave transmission efficiency and the effect of preventing marine organism attachment.

[0010] Furthermore, the transducer housing is provided with external threads, and a connecting screw hole is provided on the side of the mounting plate away from the propeller shaft. The transducer can be screwed to the mounting plate via its own external threads and the connecting screw hole.

[0011] By adopting the above technical solution, the transducer is screwed onto the mounting plate through the mating of the external thread of the outer shell and the connecting screw hole, achieving a stable connection with the mounting plate and ensuring that the transducer will not loosen during the rotation of the propeller shaft, thus ensuring the stability of the transducer's operation and improving the effect of preventing marine organism attachment.

[0012] Furthermore, the assembly includes multiple transducers, and the clamping assembly includes multiple mounting plates. Each mounting plate is fitted onto the connecting strip through its own connecting through hole. Each transducer corresponds to a mounting plate, and each transducer is connected to the corresponding mounting plate. Each transducer is electrically connected to the receiving coil through a power line.

[0013] By adopting the above technical solution, multiple transducers are connected one-to-one with multiple mounting plates, and each mounting plate is fitted onto the connecting strap, which enables multiple transducers to be stably installed on the propeller shaft. Multiple transducers are electrically connected to the receiving coil through power lines, which allows multiple transducers to work simultaneously, enhancing the transmission range and intensity of ultrasonic waves, thereby more effectively interfering with the living environment and physiological activities of marine organisms and improving the anti-marine organism attachment effect on ship propellers.

[0014] Furthermore, an adhesive layer is provided on the arc-shaped surface.

[0015] By adopting the above technical solution and setting an adhesive layer on the arc-shaped surface, the clamping component can be more tightly clamped and fixed to the propeller shaft, enhancing the connection stability between the clamping component and the shaft, further improving the fit between the transducer and the shaft, thereby improving the sound wave transmission efficiency and enhancing the effect of preventing marine organism attachment.

[0016] Specifically, a pair of clamping plates are provided on one end of the bracket near the shaft of the propeller. The two clamping plates are arranged parallel to each other and spaced apart. Each clamping plate has a through hole for pins. The outer shell of the transmitting coil has a fixing through hole. The transmitting coil is located between the two clamping plates and can be connected to the two clamping plates by bolts passing through one of the two through holes, the fixing through hole, and the other of the two through holes in sequence and being screwed to the two clamping plates with a nut.

[0017] By adopting the above technical solution, a pair of parallel and spaced clamps are set at one end of the bracket near the propeller shaft. Through holes are opened on the clamps, and fixing through holes are opened on the outer shell of the transmitting coil. The transmitting coil is connected to the clamps with bolts and nuts, which can make the transmitting coil firmly installed on the bracket, ensuring the stable position of the transmitting coil during the operation of the ship, thereby ensuring the magnetic field coupling effect between it and the receiving coil, realizing stable wireless power supply, and providing reliable power support for the normal operation of the transducer.

[0018] Furthermore, the support also includes a diagonal brace, one end of which is connected to the frame of the support, and the other end of which is connected to the inner wall of the cabin.

[0019] By adopting the above technical solution, the diagonal bracing enhances the stability of the support, making the position of the transmitting coil more stable. This ensures stable magnetic field coupling and power transmission between the transmitting and receiving coils, improves the reliability and stability of wireless power supply, and thus ensures that the transducer can work continuously and stably, enhancing the propeller's effectiveness in preventing marine organism attachment.

[0020] Specifically, the power supply component also includes a display, which is mounted on the bracket and electrically connected to the transmitting coil.

[0021] By adopting the above technical solution, a display electrically connected to the transmitting coil is installed on the bracket, which can display the operating status of the transmitting coil, power supply parameters and other information in real time. This makes it convenient for operators to monitor and manage the wireless power supply, promptly detect and deal with potential power supply problems, and improve the reliability and stability of the device.

[0022] In summary, this application includes the following beneficial technical effects: The device includes a clamping assembly, a transducer, and a power supply assembly. The clamping assembly is clamped and fixed to the propeller shaft. The transducer is mounted on the clamping assembly. The power supply assembly includes a bracket, a transmitting coil, and a receiving coil. One end of the bracket is mounted on the inner wall of the ship, and the other end is connected to the transmitting coil. The transmitting coil is electrically connected to the receiving coil via a magnetic field. The receiving coil is fitted onto the propeller shaft and can rotate with the shaft. The receiving coil is also electrically connected to the transducer, allowing the clamping assembly to securely mount the transducer onto the propeller shaft. The transmitting coil of the power supply assembly is electrically connected to the receiving coil, which is fitted onto the shaft and rotates with it, via a magnetic field, thereby supplying power to the transducer. This ensures stable operation of the transducer, effectively disrupting the living environment and physiological activities of marine organisms and preventing them from adhering to the propeller surface. Compared to existing technologies that connect to power supply equipment via power lines and require the transducer to be mounted outside the propeller shaft via a bearing structure, resulting in poor sound wave transmission efficiency and weak anti-adhesion effect due to gaps between the transducer and the shaft, this device avoids the gap problem, improves sound wave transmission efficiency, and enhances the anti-adhesion effect.

[0025] The following is in conjunction with the appendix Figure 1-3 Further explanation: See Figure 1 and Figure 3 The present application provides a wirelessly powered propeller-based marine biological defense device, comprising: a clamping assembly 1, a power supply assembly 3, and six transducers 2. The propeller shaft 4 extends into the ship's interior through a through-hole in the outer wall of the vessel and is connected to the engine and other equipment for transmission. The clamping assembly 1 includes six mounting plates 11, two connecting straps 12, and two connecting bolts 13. Each mounting plate 11 has an arc-shaped surface on one side that matches the shaft of the propeller shaft 4, and a connecting screw hole is provided on the other side of each mounting plate 11. Each transducer 2 corresponds to a mounting plate 11, and each transducer 2 has an external thread on its outer shell, and each transducer 2 can connect to the corresponding transducer 2 via its own external thread. A connecting screw hole is used for screwing, and the transducer 2 can be an ultrasonic transducer 2; two connecting through holes are opened on one side of each mounting plate 11 along the circumference of the propeller shaft 4, and connecting ears are provided at both ends of each connecting band 12. The six mounting plates 11 are all fitted onto the two connecting bands 12 through their own two connecting through holes, and each connecting band 12 can be fitted onto the shaft of the propeller shaft 4. The two ends of the connecting band 12 are connected by connecting bolts 13 through the ear holes of the two connecting ears and screwed to nuts, and the six arc surfaces are pressed against the shaft of the propeller shaft 4 so that the six transducers 2 can be stably installed on the shaft of the propeller shaft 4 and rotate together with the propeller shaft 4.

[0026] See Figure 1 and Figure 2The power supply assembly 3 includes a bracket 31, a transmitting coil 32, a display 34, and a receiving coil 33. The bottom end of the bracket 31 is located on the inner wall of the ship, and the top end of the bracket 31 is provided with a pair of clamping plates 311. The plates of the two clamping plates 311 are arranged parallel and spaced apart. Each clamping plate 311 has a through hole for a pin. The outer shell of the transmitting coil 32 has a fixing through hole, and the transmitting coil 32 is located between the two clamping plates 311. It can be connected to the two clamping plates 311 by bolts sequentially passing through one of the two through holes, the fixing through hole, and the other of the two through holes and being screwed with a nut. Three diagonal braces 312 are evenly spaced around the central axis of the support 31 between the middle of the frame 31 and the inner wall of the cabin. The diagonal braces 312 enhance the stability of the support 31 and make the position of the transmitting coil 32 more stable. The display 34 is mounted on the support 31 and electrically connected to the transmitting coil 32 through the power cable 21. The display 34 can display the working status, power supply parameters and other information of the transmitting coil 32 in real time, so that the operator can monitor and manage the wireless power supply, detect and deal with possible power supply problems in a timely manner, and improve the reliability and stability of the device.

[0027] See Figure 1 and Figure 2 The receiving coil 33 can be composed of two arc-shaped housings, two splicing blocks 331, and multiple coils. The two arc-shaped housings and the two splicing blocks 331 are arranged alternately. Each arc-shaped housing has a screw hole at its end for connecting with the rod end of a bolt or a countersunk hole for accommodating the screw head end of a bolt. Each splicing block 331 has a through hole so that the user can connect the two arc-shaped housings and the two splicing blocks 331 to form an annular housing that is tightly fixed to the propeller shaft 4 by sequentially passing a bolt through the countersunk hole of one arc-shaped housing, the through hole of one splicing block 331, and the screw hole of another arc-shaped housing. Multiple coils are arranged inside the annular housing and arranged in at least one turn around the circumference of the propeller shaft 4. Each transducer 2 is electrically connected to the receiving coil 33 through a power line 21.

[0028] Specifically, the connecting strip can be made of stainless steel and an adhesive layer is provided on each arc surface so that the clamping component 1 can be more tightly clamped and fixed on the propeller shaft 4, enhancing the connection stability between the clamping component 1 and the shaft 4, further improving the fit between the transducer 2 and the shaft 4, thereby improving the sound wave transmission efficiency and enhancing the effect of preventing marine organisms from attaching.

[0029] The working principle of the wirelessly powered propeller-based marine organism defense device of this application is as follows: The clamping assembly 1 securely mounts the transducer 2 onto the propeller shaft 4. Both the transducer 2 and the receiving coil 33 rotate together with the propeller shaft 4. This allows the transmitting coil 32 of the power supply assembly 3 to apply a magnetic field to the receiving coil 33 to power the transducer 2, ensuring stable operation of the transducer 2. This effectively disrupts the living environment and physiological activities of marine organisms, preventing them from adhering to the propeller surface. Compared to existing technologies where the transducer 2 is connected to the power supply via a power cable 21 and mounted on the outside of the propeller shaft 4 via a bearing structure, resulting in poor sound wave transmission efficiency and weak anti-adhesion effect due to gaps between the transducer 2 and the shaft 4, this device avoids the gap problem, improves sound wave transmission efficiency, and enhances the anti-adhesion effect.

[0030] It should be noted that the above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
