Description

Technical Field

[0001] The utility model relates to a universal intelligent multi-frequency ultrasonic underwater facility, and more specifically to a universal intelligent multi-frequency ultrasonic underwater facility anti-fouling device. The utility model is widely used in aquaculture, ships, wind power generation underwater bases, drilling platforms, marine ranches and other offshore facilities. Background Art

[0002] Existing ultrasonic anti-fouling devices for ships are installed on the bottom of the ship's hull, directly contacting it. Long-term exposure to ultrasonic waves can damage the hull and cause material degradation. Furthermore, direct contact with the hull limits the effective anti-fouling area to just one meter, resulting in a fixed frequency and an anti-fouling efficiency of only 60%. Existing underwater facilities, such as aquaculture and underwater structures, lack anti-fouling systems, making cleaning extremely time-consuming and labor-intensive. Utility Model Content

[0003] To address the challenges of existing technologies, the present invention provides a universal intelligent multi-frequency ultrasonic anti-fouling device for underwater facilities. This device can be installed externally to a universal intelligent multi-frequency ultrasonic underwater facility and operate underwater. The ultrasonic force field it generates creates a protective layer, preventing biofouling on the underwater facility. Its anti-fouling efficiency can reach 90%.

[0004] The technical solution of this utility model is a universal intelligent multi-frequency ultrasonic anti-fouling device for underwater facilities, comprising a flexible housing, the upper surface of which is provided with multiple adsorption devices capable of connecting to external facilities, and the lower surface of which is provided with multiple multi-frequency ultrasonic transducers. The housing is made of deformable plastic, which is plastic and deformable. During installation, high-strength magnets or strong suction cups are used to better conform to the shape of objects and adapt to facilities of different shapes. The device is installed outside the facility and immersed in water, without damaging the facility, and is easy to install.

[0005] The multi-frequency ultrasonic transducer comprises an acoustic amplifier, a multi-frequency ultrasonic vibrator, and an adaptive transducer. The acoustic amplifier is fixed to the head end of the multi-frequency ultrasonic vibrator, while the tail end of the multi-frequency ultrasonic vibrator is connected to the adaptive transducer circuit board via a board-end connection cable. The tail end of the adaptive transducer is mounted on the bottom surface of the flexible housing. When powered on, the adaptive transducer selects the corresponding frequency band (19kHz-300kHz) based on the frequency of the multi-frequency ultrasonic vibrator. Piezoelectric ceramics then convert the electrical signal into a mechanical signal at a rate of 20,000 times per second, which is then transmitted through water as a medium. A chip in the adaptive transducer circuit board adjusts the frequency and resonance point of the sound wave, amplifying the ultrasonic power by more than three times.

[0006] A main control board is also provided in the flexible shell, and a plurality of multi-frequency ultrasonic transducers are connected to the main control board via waterproof cables.

[0007] Furthermore, the device also includes a wireless antenna connected to the main control board via a waterproof cable. The antenna can transmit 4G, 5G, Wi-Fi, and Bluetooth signals. Each ultrasonic transducer operates independently and is centrally controlled by an internal integrated circuit. Wireless signals are transmitted to a remote device, allowing for remote control via a mobile app.

[0008] Furthermore, the acoustic amplifier is fabricated based on the Mach loop principle. It is a barrel-shaped structure with openings at both the head and tail ends. The central channel gradually narrows and then widens, and the opening at the head end of the amplifier is larger than the opening at the tail end. The tail end of the amplifier is connected to the head end of the multi-frequency ultrasonic transducer. After the sound wave passes through the channel, its energy is compressed and then emitted from the large opening. This creates a pressure differential between the inside and outside of the sound wave. When the external pressure is greater than the internal pressure, the sound wave is fixed in a straight line for transmission. Energy is reflected within the pressure differential, and the focus of the reflection forms a Mach loop. The acoustic amplifier is installed on the transducer head. Based on the Mach loop principle, the power and range of the sound wave are multiplied, achieving high-power, wide-range anti-fouling while maintaining low energy consumption. This extends the effective ultrasonic range from 5 meters to 10 meters.

[0009] Furthermore, the adsorption device is a high-strength magnet or a strong suction cup.

[0010] Furthermore, the device includes a buoyant ball in the form of a spherical segment, the bottom surface of which is provided with multiple connecting components that can be fixedly connected to the adsorption device on the upper surface of the flexible shell. The buoyant ball is hollow in the middle, providing buoyancy, allowing the device to float on the water surface of the cage, allowing the multi-frequency ultrasonic transducer below to better interact with the water.

[0011] Furthermore, the connecting component is a permanent magnet.

[0012] Furthermore, a camera is provided on the top of the float, which is connected to the main control board via a waterproof cable for use in environmental monitoring.

[0013] Furthermore, the tail end of the multi-frequency ultrasonic transducer is installed into the interior of the flexible housing through the hole on the lower surface of the flexible housing, and then connected with sealing glue.

[0014] Furthermore, the multi-frequency ultrasonic transducers are arranged horizontally on the lower surface of the flexible housing and evenly distributed in eight directions in a circular pattern. This can be used for anti-fouling applications on flat structures such as ships. They are attached to the bottom of the ship or other surfaces via permanent magnetic chucks. Different connection methods can be used for different materials.

[0015] Furthermore, there are eight multi-frequency ultrasonic transducers, which are placed at a 45-degree angle to the lower surface of the flexible housing and are evenly distributed in an annular shape in eight directions;

[0016] A multi-frequency ultrasonic transducer is also positioned perpendicularly to the lower surface of the flexible housing, located at the center of the lower surface. This can be used to prevent fouling of cages and net bottoms in aquaculture and to repel harmful organisms in the aquaculture water.

[0017] The beneficial effects of the utility model are:

[0018] 1. Composed of more than eight sets of multi-frequency ultrasonic transducers, it provides 360-degree coverage. The frequency is adjustable, and through intelligent control of the power at the resonance point, the low power of approximately 50-100W is increased to over 150-300W, more than tripling the power, adapting to the anti-fouling needs of different environments.

[0019] 2. The transducer head is equipped with an acoustic amplifier. Based on the Mach loop principle, the power and range of the acoustic wave are multiplied. Under the premise of low energy consumption, high power and wide range anti-fouling are achieved. The effective ultrasonic distance is extended to 10 meters.

[0020] 3. Each ultrasonic transducer can work independently and is centrally controlled by the internal integrated circuit, sent to the remote end via wireless signals, and the device is controlled by mobile app software.

[0021] 4. The shell is made of deformable plastic, which is plastic and deformable. During installation, it can be installed with high-strength magnets or strong suction cups to better fit the shape of the object and adapt to facilities of different shapes.

[0022] 5. The device is installed outside the facility and immersed in water without damaging the facility. It is easy to install and can be used for anti-fouling in aquaculture through the float accessories. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] like Figure 2 、 9 As shown, the universal intelligent multi-frequency ultrasonic underwater facility anti-fouling device includes a flexible housing 7, the upper surface of which is provided with multiple high-strength magnets or strong suction cups 11 capable of connecting to external facilities, and the lower surface of the flexible housing 7 is provided with eight multi-frequency ultrasonic transducers 6. Preferably, the tail ends of the multi-frequency ultrasonic transducers 6 are installed inside the flexible housing through holes in the lower surface of the flexible housing 7 and then connected with sealing glue.

[0035] Eight multi-frequency ultrasonic transducers 6 are placed horizontally on the lower surface of the flexible housing 7 and evenly distributed in eight directions in a circular pattern. This can be used for antifouling purposes on flat structures such as ships. They are attached to the bottom of the ship or other surfaces via permanent magnetic chucks. Different connection methods can be used for different materials.

[0036] The housing is made of deformable plastic, which is flexible and adaptable. During installation, high-strength magnets or strong suction cups are used to better conform to the shape of the object and adapt to the various shapes of facilities. The device is installed outside the facility and immersed in water without damaging the facility, making it easy to install.

[0037] The multi-frequency ultrasonic transducer 6 includes an acoustic wave amplifier 1, a multi-frequency ultrasonic vibrator 2, and an adaptive transducer 3. The acoustic wave amplifier 1 is fixed to the head end of the multi-frequency ultrasonic vibrator 2, and the tail end of the multi-frequency ultrasonic vibrator 2 is connected to the adaptive transducer 3 circuit board via a board-end connecting line. The tail end of the adaptive transducer 3 is mounted on the lower surface of the flexible housing 7. After power is turned on, the adaptive transducer selects the corresponding frequency band according to the frequency of the multi-frequency ultrasonic vibrator, ranging from 19 kHz to 300 kHz. Then, the piezoelectric ceramic converts the electrical signal into a mechanical signal at 20,000 times per second, which is then transmitted out through water as a medium. The chip in the adaptive transducer circuit board adjusts the frequency and the resonance point of the sound wave, amplifying the ultrasonic power by more than 3 times.

[0038] Preferably, the acoustic amplifier 1 is manufactured based on the Mach loop principle. It is a barrel-shaped structure with openings at both the head and tail ends. The central channel gradually narrows and then widens. The head end opening of the acoustic amplifier 1 is larger than the tail end opening, which is connected to the head end of the multi-frequency ultrasonic transducer 2. After the sound wave is squeezed through the channel, its energy is compressed and then emitted from the large opening. This creates a pressure difference between the inside and outside of the sound wave. When the external pressure is greater than the internal pressure, the sound wave is fixed in a straight line for transmission. Energy is reflected within the pressure difference range, and the focus of the reflection forms a Mach loop. The acoustic amplifier is mounted on the transducer head. Based on the Mach loop principle, the power and range of the sound wave are multiplied, achieving high-power, wide-range anti-fouling while maintaining low energy consumption. The effective ultrasonic range is expanded from 5 meters to 10 meters.

[0039] A main control board 8 is further provided in the flexible housing 7 , and the plurality of multi-frequency ultrasonic transducers 6 are connected to the main control board 8 via waterproof cables 9 .

[0040] The universal intelligent multi-frequency ultrasonic underwater facility anti-fouling device also includes a wireless antenna 4, which is connected to the main control board 8 via a waterproof cable 9. The wireless antenna can transmit 4G, 5G, Wi-Fi, and Bluetooth signals. Each ultrasonic transducer can operate independently and is centrally controlled by an internal integrated circuit. Wireless signals are transmitted to a remote device and controlled via a mobile app, enabling remote control.

[0041] Preferably, Figure 1-8As shown, the universal intelligent multi-frequency ultrasonic underwater facility anti-fouling device also includes a float 10 in the shape of a spherical segment. The bottom surface of the segment is equipped with multiple permanent magnets that can be fixedly connected to the adsorption device on the upper surface of the flexible housing 7. The center of the float is hollow, which increases buoyancy, allowing the device to float on the surface of the cage water, allowing the multi-frequency ultrasonic transducer below to better penetrate the water. A camera 5 is installed on the top of the float 10, connected to the main control board 8 via a waterproof cable 9. This is used for environmental monitoring. Eight multi-frequency ultrasonic transducers 6 can be provided, positioned at a 45-degree angle to the lower surface of the flexible housing 7 and evenly distributed in eight directions in a circular pattern. A multi-frequency ultrasonic transducer 6 is also located at the center of the lower surface of the flexible housing 7, perpendicular to the lower surface. This device can be used to prevent fouling in cages and net bottoms in aquaculture. It can also repel harmful organisms in the aquaculture water.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
