Description

Technical Field

[0001] This utility model relates to the field of marine biological defense equipment technology, specifically an ultrasonic marine biological defense control box. Background Technology

[0002] Large structures located below the sea surface, such as ships, marine structures, offshore wind farms, and marine ranches, are susceptible to varying degrees of marine biofouling. This contamination begins to appear within hours of the structure's surface being submerged. Therefore, to maintain the structural performance of these objects, these surfaces require protection and regular cleaning to remove (remove) fouling such as algae, weeds, barnacles, and mollusks. The basis of contamination for large structures in seawater, such as ships, marine structures, offshore wind farms, and marine ranches, is the biofilm that forms on these structures, which constitutes the adhesive material between marine or aquatic organisms and the structure. Biofilms form first, followed by fouling organisms attaching to all underwater structures; therefore, the more diverse, complex, or large the structure, the more difficult and expensive it is to remove biofilms and these organisms. Fouling is a major problem, leading to increased fuel consumption by ships, thus exacerbating air pollution. It also leads to the spread of alien species not native to the distant local marine environment.

[0003] Underwater surfaces are typically protected by coatings to prevent biofouling, often containing metallic copper. These coatings often decompose into the ocean, resulting in thousands of tons of toxic substances entering the marine environment each year. Furthermore, coatings do not completely prevent biofouling and still require regular cleaning. Cleaning of ships, large marine structures, offshore wind farms, and marine ranches usually involves using brushes, scrapers, and other abrasive methods, as well as high-pressure water jets. Abrasive methods can damage welds and rivets, compromising the mechanical integrity of the structure, or require the ship to enter dry dock. This is not only extremely costly, but current cleaning methods are also labor-intensive and not thorough enough, often leaving biofilms and damaging one or more layers of paint on underwater structures, which may require repainting or recoating. The coatings removed from the ship can also damage the surrounding marine environment. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic marine organism control box, comprising a control box body, a selector switch and a nameplate on the upper surface of the control box body, a relay, an ultrasonic card, wiring terminals and a switching power supply inside the control box body, a connecting shell fixedly connected to the lower surface of the control box body, a reinforcing support rod fixedly connected inside the connecting shell, a movable plate sleeved on the outer surface of the reinforcing support rod, a connecting rod fixedly connected to the lower surface of the movable plate, a buffer spring fixedly connected to the upper surface of the movable plate, a sealing ring provided in the through hole at the bottom of the connecting shell, and a mounting plate fixedly connected to the bottom end of the connecting rod.

[0009] Preferably, the mounting plate is positioned directly below the connecting housing.

[0010] Beneficial effects

[0011] This utility model provides an ultrasonic marine organism control box. It has the following beneficial effects:

[0012] (1) The ultrasonic anti-marine organism control box, through the cooperation between the control box body, relay and ultrasonic card, uses ultrasonic waves to generate a large number of tiny bubbles on the surface of the ship in the liquid. When the sound pressure reaches a certain value, the bubbles rapidly increase in size and then suddenly close. When the bubbles close, a shock wave is generated, which generates a pressure of several atmospheres around them, preventing marine organisms from attaching. This keeps the surface of the ship clean for a long time and extends the service life of the ship.

[0013] (2) The ultrasonic marine organism control box, through the cooperation between the connecting shell, the reinforcing support rod, the buffer spring and the sealing ring, the elasticity of the buffer spring can convert most of the impact force on the control box body into elastic potential energy, which plays a buffering role, so as to prevent the control box body from being subjected to large impact force for a long time, causing the installation plate to loosen, thus improving the stability of the control box body installation.

The upper surface of the control box body 1 is provided with a changeover switch 2 and a nameplate 3. The inside of the control box body 1 is provided with a relay 4, an ultrasonic card 5, a wiring terminal 6 and a switching power supply 14. The lower surface of the control box body 1 is fixedly connected to a connecting housing 7. The inside of the connecting housing 7 is fixedly connected to a reinforcing support rod 8. The outer surface of the reinforcing support rod 8 is fitted with a movable plate 9. The lower surface of the movable plate 9 is fixedly connected to a connecting rod 10. The upper surface of the movable plate 9 is fixedly connected to a buffer spring 11. A sealing ring 13 is provided in the through hole at the bottom of the connecting housing 7. The bottom end of the connecting rod 10 is fixedly connected to a mounting plate 12.

[0022] Specifically, the two ends of the reinforcing strut 8 are fixedly connected to the bottom and top of the inner surface of the connecting housing 7, respectively, and the connecting rod 10 and the buffer spring 11 are arranged at the intervals of the reinforcing strut 8.

[0023] Specifically, the outer surface of the connecting rod 10 penetrates the sealing ring 13, and the outer surface of the connecting rod 10 is fitted and adapted to the inside of the sealing ring 13.

[0024] Specifically, the end of the buffer spring 11 away from the movable plate 9 is fixedly connected to the top of the inner surface of the connecting housing 7.

[0025] Specifically, the mounting plate 12 is positioned directly below the connecting housing 7.

[0026] The working principle and beneficial effects of the above embodiments.

[0027] In use, the control box body 1 is mounted on the hull surface via mounting plate 12. Multiple control box bodies 1 distributed at intervals on the hull surface protect the entire hull. The control box body 1 generates extremely high frequencies (typically between 20-40 kHz) to drive ultrasonic sensors to produce ultrasonic waves. The ultrasonic wave particles propagate perpendicular to the resonant surface, interacting with the cavitation of the liquid medium. High-intensity ultrasonic waves generate micro-vapor / vacuum bubbles, which grow to a maximum size proportional to the applied ultrasonic frequency before imploding, releasing their energy. The higher the frequency, the smaller the cavitation size. High-intensity ultrasonic waves can also push the cavitation to its limit in a single cycle. At 20 kHz, the bubble diameter is approximately 170 micrometers. The energy released by the implosion near the surface collides with contaminants, causing fragmentation or decomposition, etc. The cumulative effect of millions of times in the liquid medium provides the necessary mechanical energy, making it impossible for marine organisms to adhere to the hull surface, thus keeping the hull surface clean for a long time. Generally speaking, at low frequencies (20-30kHz), a relatively small amount of energy is generated, while at higher frequencies, cavitation with greater density and medium or lower energy is formed. Low frequencies are more suitable for cleaning heavy and large-sized components. When the control box body 1 is impacted by water flow during the hull's movement, the buffer spring 11 deforms, converting most of the impact force into elastic potential energy, which plays a buffering role to prevent the control box body 1 from being subjected to large impact forces for a long time, causing the mounting plate 12 to become loose. The reinforcing strut 8 is used to ensure the rigidity of the connecting housing 7, and the sealing ring 13 is used to prevent water from entering the connecting housing 7.
