Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to an ultrasonic organism repelling device for an underwater hull of a ship. Background Art

[0002] The attachment of underwater organisms to the hull surfaces of ships navigating the ocean has long plagued the shipping industry. The attachment of organisms such as algae, shellfish, and barnacles significantly increases the roughness of the hull, significantly increasing the ship's sailing resistance, which in turn increases fuel consumption and reduces sailing efficiency. Furthermore, biofouling can damage the hull's anti-corrosion coating, accelerating corrosion and shortening the ship's overall service life. Current methods for combating underwater biofouling, such as antifouling paint and electrolytic antifouling devices, have significant drawbacks. Toxic substances contained in antifouling paint can seriously pollute the marine environment, significantly limiting their use amidst increasingly stringent environmental regulations. While electrolytic antifouling devices can inhibit biofouling by electrolyzing seawater to produce substances such as chlorine, they are complex and expensive, and pose safety risks such as chlorine leaks. Therefore, the development of an environmentally friendly, efficient, and low-cost biorepellent device for ships is urgent. Among various biorepellent technologies, ultrasonic biorepellent has become a key research area due to its environmental advantages. However, existing ultrasonic biorepellent devices for ships still need to be improved in terms of ultrasound reflection accuracy, coverage, and adaptability to different organisms.

[0009] The present invention is further configured such that both the first end shell and the second end shell are provided with heat dissipation grooves distributed at equal distances, and heat dissipation fins are fixed to the inner walls of the heat dissipation grooves.

[0014] In summary, after adopting the above structure, the present invention has the following advantages compared with the prior art: 1. The present invention, through the provision of an ultrasonic generating device and an ultrasonic focusing and diffusion switching mechanism, utilizes the cooperation of a guide groove, a guide frame, a movable frame, an arc-shaped extrusion plate, a slider, a reflective panel, and a reciprocating assembly to achieve switching between ultrasonic focusing and diffusion states. That is, the reciprocating assembly can conveniently adjust the position of the movable frame, thereby driving the movement of components such as the arc-shaped extrusion plate, thereby effectively controlling the shape of the reflective panel. When the reflective panel forms a convex curve or a flat surface facing the direction of the ultrasonic wave, the sound waves will diverge in all directions. When the reflective panel forms a concave surface facing the direction of the ultrasonic wave, the sound waves tend to converge. Thus, the propagation direction of the ultrasonic wave is changed by utilizing the principle of an acoustic lens. When it is necessary to precisely repel organisms in a specific area, the focusing mode can be switched to enhance the intensity of the ultrasonic wave in that area. When it is necessary to repel organisms over a large area, the diffusion mode can be switched to expand the repelling range, thereby improving the flexibility and adaptability of the repelling effect. The function of adjusting the shape of the emitting surface in real time according to actual needs is realized, and the ultrasonic focusing and diffusion states can be flexibly switched.

[0015] 2. In the present invention, since the reflective panel is made of flexible metal material and an anti-transmission film is provided on the side away from the side frame, it can not only effectively reflect ultrasonic waves, but also prevent water or other substances from penetrating, thereby protecting the internal structure from damage and extending the service life of the device. At the same time, the arrangement of the spring and guide rod in the limit groove enables the slider to have a certain buffering and reset function when sliding in the limit groove, thereby enhancing the stability and reliability of the device.

[0016] 3. In the present invention, since the ultrasonic generator has a multi-frequency composite ultrasonic generating function and can simultaneously emit ultrasonic waves of multiple different frequencies, different types of underwater organisms have different sensitive frequencies to ultrasonic waves. By emitting composite ultrasonic waves containing multiple frequency components, multiple organisms can be simultaneously repelled, achieving the function of repelling multiple common attached organisms at one time. There is no need to adjust the equipment for each single organism separately, thereby improving the versatility and practicality of the device and improving the repelling efficiency.

[0017] 4. In the present invention, an ultrasonic repelling module array consisting of two ultrasonic reflective units is installed on the outer shell of the underwater hull, and each ultrasonic repelling module array is equipped with an independent direction-changing assembly. The top frame, support frame, first steering shaft, portal frame, first mounting shaft, second steering shaft, first swing arm, second swing arm, second mounting shaft, and waterproof motor in the direction-changing assembly cooperate to achieve flexible multi-angle steering adjustment of the mounting base and ultrasonic emitting unit. The ultrasonic emission direction can be dynamically adjusted according to actual needs, thereby expanding the repelling range, improving the practical performance of the repelling device, and achieving precise repelling.

[0018] 5. In the present invention, LED lights installed on the side frames can emit light of different colors and flashing frequencies. Since many underwater creatures are phototactic, light of different colors and frequencies can effectively repel underwater creatures. In addition, a conductive layer provided inside the underwater shell of the hull is connected to a power source to form a weak electric field, which can also have a repelling effect on some creatures. This forms a function that combines multiple repelling methods, thereby improving the overall repelling effect.

[0019] 6. In the present invention, the entire device is equipped with an intelligent controller and a biosensor, which can monitor the biological species, density and other parameters around the hull in real time through the biosensor. Based on these monitoring data, the intelligent controller automatically adjusts the working parameters of the ultrasonic reflection unit, the conductive layer, the LED light and the direction-changing component to achieve automated and intelligent biological expulsion, thereby improving the expulsion efficiency while saving energy and labor costs.

An ultrasonic generating device is provided on the side frame 8 and the mounting seat 7. The ultrasonic generating device includes a mounting rod 14 fixed to the inner walls of both sides of the side frame 8, and a first end shell 10 is fixed at one end of the mounting rod 14. An ultrasonic transducer 15 is installed in the first end shell 10. A waterproof sound-permeable membrane 9 is fixed to the outer wall of the first end shell 10 and one end of the inner wall around the side frame 8. A second end shell 12 is fixed in the middle position of one side of the mounting seat 7, and an ultrasonic generator 22 with a multi-frequency composite ultrasonic generating function is installed in the second end shell 12. The ultrasonic generator 22 is electrically connected to the ultrasonic transducer 15, and the ultrasonic generator 22 can generate a frequency of 20kHz-10 Ultrasonic waves in the range of 0kHz enable the entire device to have a multi-frequency composite ultrasonic generating function, which can simultaneously emit ultrasonic waves of multiple different frequencies. Different types of underwater organisms have different sensitive frequencies to ultrasonic waves. For example, the 40kHz frequency sensitive to algae, the 60kHz frequency sensitive to shellfish, and the 80kHz frequency sensitive to barnacles are compounded to expel multiple common attached organisms at one time, thereby improving the expulsion efficiency. The first end shell 10 and the second end shell 12 are both provided with equidistantly distributed heat dissipation grooves, and the inner walls of the heat dissipation grooves are fixed with heat dissipation fins 13. The heat generated by the work can be dissipated in time through the heat dissipation grooves and the heat dissipation fins 13 to ensure stable operation of the device. An ultrasonic focusing and diffusion switching mechanism is provided inside the central cavity 24. The ultrasonic focusing and diffusion switching mechanism includes a guide groove 25 provided in the middle of the top and the middle of the bottom of the central cavity 24, and the inner walls of the two guide grooves 25 are respectively slid with a guide frame 32 and a movable frame 19, and a reciprocating assembly for adjusting the position of the movable frame 19 is provided in the guide groove 25 at the bottom, and the reciprocating assembly includes a threaded rod 18 rotating in the bottom guide groove 25, and a threaded groove adapted to the outer wall of the threaded rod 18 is provided in the middle of the movable frame 19, and a forward and reverse motor 20 for driving the threaded rod 18 to rotate is installed in the guide groove 25, a guide rod 16 is fixed in the guide groove 25 at the top, and a guide hole for the guide rod 16 to pass through is provided in the middle of the mounting frame 23, and both ends of the movable frame 19 and the two ends of the guide frame 32 are fixed with reinforcing A reinforcing rod 31 is provided, and four arc-shaped extrusion plates 28 are fixed on the reinforcing rod 31, wherein the two arc-shaped extrusion plates 28 on the same side are fixed with connecting rods 27 at both ends, and limiting grooves 26 are provided at both ends of the top and bottom of the central cavity 24, and sliders 29 are slid in the limiting grooves 26, and guide rods 33 are fixed to the inner walls of the limiting grooves 26, and guide holes for the guide rods 33 to pass through are provided on the sliders 29, and a spring 30 is installed on one side of the slider 29 and one side of the limiting groove 26, and the spring 30 is sleeved on the guide rod 33, and a mounting bracket 23 is rotated between the two perpendicular sliders 29, and a reflective panel 17 is installed between the two mounting brackets 23, and the reflective panel 17 is located between the four arc-shaped extrusion plates 28, and the reflective panel 17 is made of flexible metal material.An anti-permeability film 21 is provided on the side of the reflective panel 17 away from the side frame 8. When it is necessary to switch the focusing and diffusion states of the ultrasound, the forward and reverse motor 20 is used to drive the threaded rod 18 to rotate, causing the movable frame 19 to move, driving the reinforcement rod 31, the guide frame 32 and the four arc-shaped extrusion plates 28 to move synchronously. The arc-shaped extrusion plates 28 are used to squeeze the reflective panel 17 to deform it. When the reflective panel 17 forms a convex curve or a flat surface facing the direction of the ultrasound, the sound waves will diverge in all directions; when the reflective panel surface 17 forms a concave surface facing the direction of the ultrasound, the sound waves tend to converge. The principle of the acoustic lens is used to change the propagation direction of the ultrasound. When it is necessary to accurately expel organisms in a specific area, the focus mode can be switched to enhance the intensity of the ultrasound in that area. When it is necessary to expel organisms over a large area, the diffusion mode can be switched to expand the expulsion range, improving the flexibility and adaptability of the expulsion effect. This realizes the function of adjusting the shape of the emitting surface in real time according to actual needs, and flexibly switching the focusing and diffusion states of the ultrasound.

[0026] In the present invention, each ultrasonic drive module array is mounted on the outer wall of the hull 1 with a mounting bracket 5, and the direction-changing component 6 includes a top frame 603 and a support frame 607 fixed to one side of the mounting bracket 5, and the support frame 607 is fixed to the middle of the bottom of the top frame 603. Both ends of the top frame 603 are rotatably connected to the first steering shaft 604 through a sealed bearing, and the bottom of the first steering shaft 604 is fixed with a door frame 605, and both ends of the door frame 605 are rotatably connected to the first mounting shaft 601, and the first mounting shaft 601 is fixedly mounted on the middle of both sides of the mounting seat 7. The outer walls of the two first steering shafts 604 are fixed with transmission wheels, and the two transmission wheels are fixed to the outer walls of the two first steering shafts 604. The transmission is connected with a transmission belt 610, a gear box 608 is fixedly installed at the bottom of the support frame 607, and a second steering shaft 611 is rotated on the gear box 608, and the two ends of the second steering shaft 611 are fixed with a first swing arm 609, one end of the first swing arm 609 is rotatably connected to the second swing arm 606, and one end of the second swing arm 606 is rotatably connected to the second installation shaft 602, and the second installation shaft 602 is fixedly installed in the middle of the bottom of the mounting base 7, and the top end of the top frame 603 and the bottom inner wall of the support frame 607 are fixedly installed with a waterproof motor 612 for driving the first steering shaft 604 and the gear assembly in the gear box 608 to rotate, as shown in FIG. Figure 2 、 Figure 3 、 Figure 10 and Figure 11As shown, the waterproof motor 612 at one end of the top of the top frame 603 drives the first steering shaft 604 to rotate, and the portal frame 605 fixed at the bottom of the first steering shaft 604 rotates accordingly. The portal frame 605 is connected to the mounting seat 7 through the first mounting shaft 601, thereby realizing the rotation of the mounting seat 7 along the direction of the first steering shaft 604. At the same time, the second steering shaft 611 on the gear box 608 at the bottom of the support frame 607 rotates under the drive of the waterproof motor 612. The first swing arms 609 at both ends of the second steering shaft 611 drive the second swing arms 606 to move. The second swing arms 606 are connected to the mounting seat 7 through the second mounting shaft 602, realizing the rotation of the mounting seat 7 along the direction of the second steering shaft 611. The rotation in two directions can adjust the mounting seat 7 and the ultrasonic repelling module array to different angles, so that ultrasonic waves can be emitted in different directions to meet different repelling requirements. In addition, the waterproof motor 612 also generates vibration when working to repel organisms away from the hull 1.

[0027] In the present invention, a plurality of biosensors 3 are installed on the underwater shell of the hull 1, and an intelligent controller is installed on the hull 1. The intelligent controller is electrically connected to the biosensors 3, the waterproof motor 612, and the ultrasonic generator. Figure 1 As shown, the biosensor 3 monitors the species, density and distribution of organisms around the hull 1 in real time. At the same time, combined with the ship's navigation speed, water depth and other parameters, the intelligent controller uses a specific algorithm based on these monitoring data to adjust the working parameters of the ultrasonic repellent module array in real time, including the frequency, direction, focus or diffusion mode of each transmitting unit and the combination of multi-frequency composite, so as to achieve the best repellent effect.

[0028] In summary, the ultrasonic generator 22 generates an electrical signal and transmits it to the ultrasonic transducer 15. The ultrasonic transducer 15 converts the electrical signal into an ultrasonic signal, which is then reflected by the reflective panel 17 to the waters surrounding the hull 1 at various frequencies. Simultaneously, the heat dissipation slots and heat dissipation fins 13 on the first and second end shells 10 and 12 can promptly dissipate the heat generated during operation, ensuring stable operation of the device. When it is necessary to switch the focusing and diffusion states of the ultrasound, the forward and reverse motor 20 located in the bottom guide groove 25 drives the threaded rod 18 to rotate, so that the movable frame 19 moves axially along the threaded rod 18 in the guide groove 25, driving the reinforcement rod 31, the guide frame 32 and the four arc-shaped extrusion plates 28 to move synchronously, and the arc-shaped extrusion plates 28 are used to squeeze the reflective panel 17 to deform it. When the reflective panel 17 forms a convex curve or a flat surface facing the direction of the ultrasound, the sound waves will diverge in all directions. When the reflective panel 17 forms a concave surface facing the direction of the ultrasound, the sound waves tend to converge. The propagation direction of the ultrasound is changed by utilizing the principle of the acoustic lens. When it is necessary to accurately expel organisms in a specific area, it can be switched to the focusing mode to enhance the intensity of the ultrasound in that area. When it is necessary to expel organisms over a large area, it can be switched to the diffusion mode to expand the expulsion range, thereby improving the flexibility and adaptability of the expulsion effect, realizing the function of adjusting the shape of the emitting surface in real time according to actual needs, and flexibly switching the focusing and diffusion states of the ultrasound. When the ultrasonic emission direction needs to be changed, the waterproof motor 612 at one end of the top of the top frame 603 is used to drive the first steering shaft 604 to rotate, and the door-shaped frame 605 fixed at the bottom of the first steering shaft 604 rotates accordingly. The door-shaped frame 605 is connected to the mounting seat 7 through the first mounting shaft 601, thereby realizing the rotation of the mounting seat 7 along the direction of the first steering shaft 604. At the same time, the second steering shaft 611 on the gear box 608 at the bottom of the support frame 607 is driven by the waterproof motor 612 to rotate, and the first swing arms 609 at both ends of the second steering shaft 611 drive the second swing arm 606 to move. The second swing arm 606 is connected to the mounting seat 7 through the second mounting shaft 602, realizing the rotation of the mounting seat 7 along the direction of the second steering shaft 611. The rotation in the two directions can adjust the mounting seat 7 and the ultrasonic drive away module array to different angles, so that the ultrasonic wave can be emitted to different directions to meet different drive away requirements. The multiple biosensors 3 installed on the underwater shell of the hull 1 monitor the activity information of organisms in the surrounding waters in real time, and transmit the data to the intelligent controller on the hull 1. The intelligent controller analyzes and processes the data and intelligently controls the working status of components such as the direction-changing component 6 and the ultrasonic generator according to information such as the species and density of the organisms.

[0029] Second implementation method: This embodiment adds the following structure on the basis of the first embodiment, so that this application has the function of combining multiple expulsion methods, and the specific configuration is as follows: Figure 1 and Figure 2As shown, LED lights 11 are fixedly installed in the middle of both sides of the side frame 8. The LED lights 11 can emit light of different colors and flashing frequencies. A conductive layer 4 is set inside the underwater shell of the hull 1, and the conductive layer 4 is connected to the power supply to form a weak electric field. The intelligent controller is electrically connected to the biosensor 3, the conductive layer 4, and the LED lights 11. Light can be emitted underwater through the LED lights 11. On the one hand, it can illuminate the underwater environment. On the other hand, it has a certain repelling effect on some light-sensitive organisms. The conductive layer 4 set inside the underwater shell of the hull 1 is connected to the power supply to form a weak electric field. This electric field can generate electrical stimulation to some organisms, causing them to stay away from the hull, and work together with the ultrasonic repelling to improve the repelling effect.

[0030] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
