Description

Technical Field

[0001] This utility model relates to the field of ultrasonic antifouling technology, specifically to an ultrasonic antifouling device applied to a marine subsea filter. Background Technology

[0002] Currently, the main methods for preventing marine organisms in ship hull-mounted subsea filters are electrolytic copper, aluminum, and iron. The copper anode is electrolyzed in seawater to produce trace amounts of copper ions. Low-voltage direct current is used to electrolyze the antifouling copper alloy anode and the anti-corrosion aluminum alloy anode to produce copper and aluminum ions, which are then used to control marine organisms.

[0003] However, using electrolysis of copper and aluminum to control marine organisms is less effective against plant and slime-producing organisms. Furthermore, copper and aluminum are non-renewable resources, and the long-term release of copper and aluminum ions into seawater will pollute the environment and damage the marine ecosystem. Additionally, the anode material is consumed rapidly during electrolysis, requiring frequent replacement and increasing maintenance costs. Utility Model Content

[0004] In view of this, the present invention provides an ultrasonic antifouling device for use in marine underwater gate filters, in order to solve the problems of severe pollution and high operation and maintenance costs during the process of preventing marine organisms from entering the sea.

[0005] This utility model provides an ultrasonic antifouling device for use in marine subsea filter doors, comprising:

[0006] An ultrasonic drive box is used to generate a periodic sequence of drive signals.

[0007] An ultrasonic transducer is electrically connected to the ultrasonic drive box;

[0008] The mounting base is detachably connected to the surface to be cleaned, and the mounting base has a mounting area, on which the ultrasonic transducer is detachably connected.

[0009] The mounting base is also provided with a plurality of connecting holes, which are tapered and arranged at intervals along the circumference of the mounting base.

[0010] Beneficial Effects: By setting an installation area on the mounting base, the ultrasonic transducer can be detachably connected to the installation area. The mounting base also features several tapered connection holes to guide the connectors more accurately into the holes during installation, improving installation convenience and accuracy. Furthermore, the fit between the tapered holes and the connectors generates greater friction and pressure between the connectors and the hole walls, thereby enhancing the stability and reliability of the connection and reducing the possibility of loosening due to vibration or other external forces. The connection holes are arranged at intervals along the circumference of the mounting base, ensuring that the connection force is evenly distributed around the circumference when the mounting base is connected to the ultrasonic transducer, avoiding excessive or insufficient localized stress, thus improving the stability and strength of the entire connection structure.

[0011] This invention generates a periodic sequence of drive signals using an ultrasonic drive box, which is then transmitted to an ultrasonic transducer electrically connected to the drive box. The transducer converts the periodic drive signals into a periodic sequence of ultrasonic mechanical vibrations, thereby cleaning marine organisms from the ship's submersible filter. This invention effectively reduces the operation and maintenance costs of marine organism control and also significantly reduces pollution emissions during the process. Furthermore, by converting the periodic drive signals into a periodic sequence of ultrasonic mechanical vibrations, cavitation corrosion is reduced during ultrasonic cleaning of the ship's submersible filter, preventing damage to the hull structure.

[0012] In one alternative implementation, the driving signal of the periodic sequence satisfies 30kHz-60kHz.

[0013] In one optional embodiment, the ultrasonic transducer operates at a power of 5W-50W.

[0014] In one alternative embodiment, the mounting area includes a countersunk hole that is coaxial with the mounting base.

[0015] In one alternative embodiment, the mounting base is further provided with a sealing groove, which is disposed on the outer periphery of the countersunk hole opening.

[0016] In one optional embodiment, a bolt connection hole is further provided along the thickness direction of the mounting base, and the bolt connection hole communicates with the countersunk hole.

[0017] In one optional embodiment, the ultrasonic anti-fouling device further includes a plurality of magnetic connectors, each of which corresponds one-to-one with a plurality of connection holes.

[0018] In one alternative embodiment, the ultrasonic drive box includes an ultrasonic drive board for generating a periodic sequence of drive signals and transmitting the drive signals to the ultrasonic transducer.

[0019] In one optional embodiment, the ultrasonic drive box further includes a display unit electrically connected to the ultrasonic drive board for displaying the current operating status of the ultrasonic transducer.

[0020] In one optional implementation, the ultrasonic drive board includes an error monitoring module for detecting faults in the connection of the ultrasonic transducer.

[0021] A communication module is used to transmit the current operating status of the ultrasonic transducer to the display unit. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Related technologies also include the use of ultrasonic cleaning devices for ultrasonic cleaning. However, when using ultrasonic cleaning devices, the power of a single ultrasonic transducer is usually greater than 100W and the frequency is relatively high. The cavitation corrosion caused by high power will damage the hull structure and surface, resulting in high energy consumption and high maintenance costs.

[0031] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0032] According to embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 4 As shown, an ultrasonic antifouling device for use in marine subsea door filters is provided, comprising: an ultrasonic drive box 300 for generating a periodic sequence of drive signals; an ultrasonic transducer 400 electrically connected to the ultrasonic drive box 300; a mounting base 100 detachably connected to the surface to be cleaned, and the mounting base 100 having a mounting area 110, the ultrasonic transducer 400 being detachably connected to the mounting area 110; the mounting base 100 also having a plurality of connecting holes 120, the plurality of connecting holes 120 being conical, and the plurality of connecting holes 120 being arranged at intervals along the circumference of the mounting base 100.

[0033] In this embodiment, the mounting base 100 can be circular, with a mounting area 110 coaxial with it. The ultrasonic transducer 400 is detachably connected to the mounting area 110. The mounting base 100 also has several connecting holes 120, which are tapered. When the mounting base 100 is connected to the surface to be cleaned, the diameter of the connecting holes 120 gradually increases from the surface to be cleaned away from it. This facilitates the accurate insertion of the connector into the connecting holes 120 during installation, improving installation convenience and accuracy. Furthermore, the fit between the tapered holes and the connector generates greater friction and pressure between the connector and the hole wall, enhancing the stability and reliability of the connection and reducing the possibility of loosening due to vibration or other external forces. Then, several connecting holes 120 are arranged at intervals along the circumference of the mounting base 100. When the mounting base 100 is connected to the ultrasonic transducer 400, the connecting force is evenly applied to the circumference, avoiding excessive or insufficient local force, thereby improving the stability and strength of the entire connection structure.

[0034] Furthermore, the ultrasonic drive box 300 is connected to an external power supply 500. The ultrasonic drive box 300 converts electrical signals into a periodic sequence of drive signals, which are then transmitted to the ultrasonic transducer 400, which is electrically connected to the ultrasonic drive box 300. The ultrasonic transducer 400 converts the periodic sequence of drive signals into a periodic sequence of ultrasonic mechanical vibrations, thereby cleaning marine organisms from the ship's seabed filter. This invention effectively reduces the operation and maintenance costs of marine organism control and effectively reduces pollution emissions during the marine organism control process. Moreover, by converting the periodic sequence of drive signals into a periodic sequence of ultrasonic mechanical vibrations, cavitation corrosion is reduced during ultrasonic cleaning of the ship's seabed filter, preventing damage to the hull structure.

[0035] In one embodiment, the driving signal of the periodic sequence satisfies 30kHz-60kHz.

[0036] In this embodiment, the periodic drive signal can specifically be 30kHz, 35kHz, 40kHz, 45kHz, 50kHz, 55kHz, 60kHz, etc., and can be set according to actual usage requirements without specific limitations. The periodic drive signal can periodically change between 30kHz and 60kHz. For example, when the ultrasonic drive box 300 is started, the drive signal can be 30kHz. After a preset working time is met, the processor 313 in the ultrasonic drive box 300 can control the drive signal to increase by 5kHz until the drive signal increases to 60kHz. Then, after a preset working time is met, the drive signal is changed back to 30kHz, thereby realizing the setting of the periodic drive signal for application in different scenarios, improving the cleaning effect of the ship's subsea filter, reducing cavitation corrosion, and preventing damage to the ship's structure.

[0037] In one embodiment, the ultrasonic transducer 400 operates at a power of 5W-50W.

[0038] In this embodiment, the operating power of the ultrasonic transducer 400 refers to the amount of energy consumed or output per unit time during the conversion of electrical energy into ultrasonic mechanical energy. The operating power of the ultrasonic transducer 400 can specifically be 5W, 10W, 15W, 20W, 30W, 50W, etc., and can be set according to actual needs. If the operating power of the ultrasonic transducer 400 is too low, such as less than 5W, it may not provide enough energy to generate effective ultrasonic vibrations. If the operating power of the ultrasonic transducer 400 is too high, such as greater than 50W, long-term operation will result in excessive energy consumption and increased operating costs. By setting an appropriate operating power for the ultrasonic transducer 400, the ultrasonic antifouling device can operate for a long time without damaging the ship's structure, making ultrasonic cleaning a routine practice and effectively improving the cleaning effect on the ship's surface.

[0039] In one embodiment, the mounting area 110 includes a countersunk hole, which is coaxial with the mounting base 100. Furthermore, the mounting base 100 is also provided with a sealing groove 140, which is disposed on the outer periphery of the countersunk hole opening.

[0040] In this embodiment, the mounting area 110 is configured as a countersunk hole, and the countersunk hole is coaxial with the mounting base 100 to facilitate the installation of the ultrasonic transducer 400 into the central area of ​​the mounting base 100, ensuring the symmetry and balance of the installation. Furthermore, a sealing groove 140 is formed around the outer periphery of the countersunk hole opening, and a sealing element, such as a sealing ring or gasket, is provided within the sealing groove 140. After the ultrasonic transducer 400 is installed in the countersunk hole and the mounting base 100 is installed on the surface to be cleaned, the sealing element prevents external liquids from entering the countersunk hole, thereby protecting the ultrasonic transducer 400 inside the countersunk hole and ensuring its normal operation.

[0041] In one embodiment, a bolt connection hole 130 is provided along the thickness direction of the mounting base 100, and the bolt connection hole 130 communicates with the countersunk hole.

[0042] In this embodiment, the bolt connection hole 130 is a channel for installing bolts to connect and fix the mounting base 100 and the ultrasonic transducer 400. After the ultrasonic transducer 400 is placed in the countersunk hole, the bolt can be inserted from the side of the mounting base 100 and extend along the bolt connection hole 130 into the countersunk hole, thereby fixing the ultrasonic transducer 400 and ensuring the stability of the ultrasonic transducer 400 connection.

[0043] like Figure 3 As shown, in one embodiment, the ultrasonic anti-fouling device further includes a plurality of magnetic connectors 200, and the plurality of magnetic connectors 200 correspond one-to-one with a plurality of connection holes 120.

[0044] In this embodiment, a plurality of magnetic connectors 200 are provided, and each of the magnetic connectors 200 is tapered, so that they correspond one-to-one with the connecting holes 120. The magnetic force of the magnetic connectors 200 fixes the mounting base 100 to the surface to be cleaned. When the mounting base 100 is connected to the surface to be cleaned, a coupling agent is used to ensure the reliability of the connection of the mounting base 100 and avoid the easy detachment that can occur when only adhesive is used between the mounting base 100 and the surface to be cleaned. Moreover, no additional tools are needed when installing the mounting base 100; the connection process can be completed simply by using magnetic attraction, which improves the assembly and maintenance efficiency of the mounting base 100.

[0045] In one embodiment, the ultrasonic drive box 300 includes an ultrasonic drive board 310 for generating a periodic sequence of drive signals and transmitting the drive signals to the ultrasonic transducer 400.

[0046] In this embodiment, the ultrasonic drive board 310 can generate a periodic sequence of drive signals based on the electrical signals from the external power supply 500. The ultrasonic drive board 310 includes a drive chip 315 and at least one MOSFET module group 316, which is electrically connected to the ultrasonic transducer 400. The drive chip 315 generates an initial electrical signal according to preset parameters, such as frequency, amplitude, and waveform. When generating the periodic sequence of drive signals, the signal generator produces a signal with a periodic variation pattern according to a preset algorithm and circuit design. The drive signal is then transmitted to the ultrasonic transducer 400 through the MOSFET module group 316, enabling the ultrasonic transducer 400 to generate ultrasonic waves of corresponding frequency and intensity according to the drive signal, thereby achieving the cleaning of the surface of the ship's seabed filter.

[0047] In one embodiment, the ultrasonic drive box 300 further includes a display unit 320 electrically connected to the ultrasonic drive board 310 for displaying the current operating status of the ultrasonic transducer 400.

[0048] In this embodiment, the display unit 320 can specifically be a light-emitting diode (LED) display screen or an LED indicator light. The display unit 320 is electrically connected to the power module 314 of the ultrasonic driver board 310, allowing the operating status of the ultrasonic transducer 400 to be displayed on the display unit 320. If the display unit 320 is an LED indicator light, the current operating status of the ultrasonic transducer can be displayed by turning the LED indicator light on and off, thus determining whether the ultrasonic transducer 400 is in operation. If the display unit 320 is an LED display screen, relevant operating information of the ultrasonic transducer 400, such as operating parameters and operating status indicators, can be displayed on the LED display screen in real time. This helps improve the operability and stability of the ultrasonic anti-fouling device, facilitating user monitoring and maintenance.

[0049] In one embodiment, the ultrasonic drive board 310 includes an error monitoring module 311 for detecting faults in the connection of the ultrasonic transducer 400; and a communication module 312 for transmitting the current operating status of the ultrasonic transducer 400 to the display unit 320.

[0050] In this embodiment, an error monitoring module 311 is used to monitor the connection status between the ultrasonic transducer 400 and the ultrasonic drive board 310 in real time, promptly detecting potential faults and ensuring the stable operation of the entire ultrasonic anti-fouling device. The error monitoring module 311 periodically sends detection signals to the ultrasonic transducer 400 and then judges the connection status based on the received feedback signals. If no correct feedback signal is received within a specified time, or if the feedback signal is abnormal, a connection fault can be identified. Additionally, the error monitoring module 311 also monitors parameters such as current and voltage in the connection lines; when these parameters exceed the normal range, a connection problem can also be identified. The communication module 312 establishes an information transmission bridge between the ultrasonic drive board 310 and the display unit 320, enabling the current operating status of the ultrasonic transducer 400 to be displayed on the display unit 320 in a timely and accurate manner. This allows users to intuitively understand the operation of the ultrasonic anti-fouling device, facilitating timely detection and handling of problems.

[0051] Understandably, the ultrasonic drive box 300 also includes a switching power supply 330, which is used to control the connection and disconnection between the ultrasonic drive box 300 and the external power supply 500, thereby controlling the working state of the ultrasonic drive box 300 so as to facilitate the normal operation of the ultrasonic anti-fouling device.

[0052] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
