Detailed description of the invention
Fig. 1 is the structural schematic diagram that a kind of underwater ultrasound provided by the invention eliminates corrosion equipment.
Specific embodiment
Presently preferred embodiments of the present invention is illustrated below according to Fig. 1.
Ultrasonic wave is the sound wave that frequency is higher than 20000 hertz, is obtained because its lower-frequency limit is approximately equal to the upper limit of hearing of people
Name, its good directionality, penetration capacity is strong, is easily obtained the sound energy relatively concentrated, and propagation distance is remote in water, can be used for ranging, surveys
Speed, cleaning, welding, rubble, sterilizing etc..In medicine, military affairs, industry, agriculturally there are many applications.It propagates in a liquid
Ultrasonic energy the dirt of body surface is cleaned, principle can be used " cavitation " phenomenon to explain: ultrasonic activation is in liquid
When the sound wave pressure propagated in body reaches an atmospheric pressure, power density 0.35w/cm2, the at this moment sound wave pressure of ultrasonic wave
Peak value just can reach vacuum or negative pressure, but actually exist without negative pressure, therefore generate a very big power in a liquid, by liquid
Molecule drawing crack is at an empty cavitation nucleus.The very close vacuum in this cavity, its rupture when ultrasonic wave pressure reversely reaches maximum, by
The dirt of body surface is hit in the intense impact that rupture generates.It is this by countless tiny cavitation bubbles ruptures and
The shock wave phenomenon of generation is known as " cavitation " phenomenon.
The present invention is based on ultrasonic cleaning principles, provide a kind of underwater ultrasound elimination corrosion equipment, include:
Supersonic generator 1 is arranged on the water surface；
Ultrasonic transducer 2 is arranged in underwater, and connects supersonic generator 1 by submerged cable, is used for ultrasonic wave
The high frequency power that generator 1 generates is converted into mechanical oscillation；
Metallic channel 3 is fixedly connected with the output end of ultrasonic transducer 2, the mechanical oscillation for exporting ultrasonic transducer 2
Pass to the seawater being located in 2 inner cavity of metallic channel.
The length long enough of submerged cable between supersonic generator 1 and ultrasonic transducer 2, to ensure ultrasonic waves
Energy device 2 and metallic channel 3 can be moved arbitrarily under water, complete the clean operation to underwater equipment all sites.
Metallic channel 3 can use arbitrary shape, as long as guaranteeing that the metallic channel has the inner cavity that can accommodate seawater.
Ultrasonic transducer 2 may be coupled to any part of metallic channel 3, pass to mechanical oscillation as long as can satisfy
Metallic channel 2, and the seawater in metal slot cavity body is driven to generate shock wave.
The present invention also provides a kind of underwater ultrasounds to eliminate caustic solution comprising the steps of:
Ultrasonic transducer and metallic channel are moved to and needed at clean underwater equipment, metallic channel is buckled into equipment under water
On erosional surface, make to form closed seawater cavity between metallic channel and erosional surface；
Supersonic generator is opened, high frequency power is converted into mechanical oscillation by ultrasonic transducer, will by cleaning metal cell wall
Seawater of the Ultrasonic Radiation into metallic channel enables the microbubble in metallic channel seawater cavity due to the radiation by ultrasonic wave
It is enough that vibration is kept under the action of sound wave, erosional surface is cleaned, the dirt and surface adsorbate on erosional surface is destroyed, causes
The fatigue rupture of crud layer and refuted from.
For the corrosion condition of underwater equipment different parts, the power of adjustable supersonic generator 1, to adjust super
The vibration frequency of acoustic wave transducer 2 and metallic channel 3 realizes better cleaning effect to adjust the power of sea washes wave.Such as
Fruit corrosion condition is not serious, then can use lesser ultrasonic power, be cleaned with weaker shock wave, to save energy
Source, and if encountering more serious erosional surface, biggish ultrasonic power can be used, is carried out clearly with stronger shock wave
It washes.
