It includes an intelligent monitoring cabinet and an ultrasonic transducer array. The intelligent monitoring cabinet is electrically connected to the ultrasonic transducer array via a main power transmission cable. This device solves the problem of large-area installation of seawater pipes without damaging the pipe structure, even in situations where space below deck is limited and movement is difficult. By using a discrete oscillator to drive the snap-ring to vibrate at high frequency, it excites higher-order bending modes in the seawater pipe, achieving a wide-range ultrasonic vibration effect to realize the three-dimensional anti-marine biofouling purpose.

Description

Technical Field

[0001] This utility model relates to the field of marine organism attachment technology, specifically to an ultrasonic marine organism attachment prevention device for a snap-ring type ship main seawater pipe. Background Technology

[0002] Currently, the main method for preventing marine organisms from entering seawater pipelines, both domestically and internationally, is the sacrificial electrode method. Although this method is effective in the early stages, its antifouling effect decreases over time, and it becomes essentially ineffective after three years, which is difficult to detect and poses a potential threat to the safety of ship operations.

[0003] Ultrasonic antifouling technology holds promise for reversing this situation, as ultrasound waves have extremely strong penetrating power into rigid shells, and high-frequency vibrations of the pipe wall can effectively prevent marine organisms from attaching. However, current methods for ultrasonic antifouling of pipelines, both domestically and internationally, primarily involve bonding a conformal transition block to the outer wall of the pipe to connect the ultrasonic probe. The main problems with this approach are:

[0004] 1. Poor sound transmission effect: Using a separate probe bonded to the pipe makes it difficult to apply prestress, resulting in poor fit between the transducer and the pipe, which often affects the sound power transmission effect.

[0005] 2. The effectiveness of three-dimensional marine organism control through pipelines is limited. For probes attached to the main seawater pipelines of operating vessels, the confined space often restricts installation and movement, making it difficult for the probes to completely cover the seawater pipe. Ultimately, this results in poor effectiveness of three-dimensional marine organism control due to low total power and limited sound field coverage.

[0006] Therefore, an ultrasonic anti-marine biofouling device for the main seawater pipe of a ship with a snap ring is proposed. Utility Model Content

The other end of the waterproof junction box is connected to the main power transmission cable.

[0011] Preferably, the ship's main seawater pipe is connected to the ship's seawater pump, which supplies water to cool the ship's engine equipment.

It is fastened to the main seawater pipe of the ship by locking bolts and ensures that it fits in close contact with the surface of the main seawater pipe of the ship.

[0013] Preferably, the ultrasonic transducer array, the mechanical coupling device, and the ship's main seawater pipe form a resonator.

[0014] Preferably, an ultrasonic power amplifier is fixedly installed inside the intelligent monitoring cabinet. The ultrasonic power amplifier provides suitable, matched, and adaptive electrical power to the resonator to ensure that the resonator works stably and efficiently, thereby preventing marine organisms from attaching to the inside of the ship's main seawater pipe.

[0015] Preferably, the intelligent monitoring cabinet is equipped with a power conversion module. The intelligent monitoring cabinet controls and monitors the power conversion module through a display control circuit to ensure the safe operation of the equipment and to provide prompts and alarms in case of a fault.

[0016] Preferably, the power transmission cable runs parallel to the ship's main seawater pipe and is electrically connected to the transducer cable and waterproof junction box, enabling individual power supply to the transducers in the ultrasonic transmitting transducer array.
