Description
Technical field
The present invention relates to anti-halobios adhersion protection device under water, particularly relate to in-site measurement sensing in ocean
The anti-halobios adhersion protection device of device.
Background technology
In ocean research field, briny environment is a special extremely complex corrosive environment, in seawater
Grow various biology, halobiontic growth and attachment to be done step-by-step according to procedure below: in seawater
Bacterial biof iotalm can be attached to instrument surface, provides foothold for planktonic larva, and planktonic organism can
Serve as barnacle, the bait of mussel adult, promote that the marine organisms settling down class are attached thereto and produce lime
Matter deposits, and the growth for algae provides control environment, and the breeding of algae is fixed further
Occupying class biology and provide food source, so circulation makes marine organisms constantly grow and breed, the completeest
All standing oceanographic instrumentation surface.
Halobiontic attachment also produces corrosion to instrument in addition to affecting normal operation of sensor, and they cover
Lid underwater camera camera lens and light source, interference sensor, flood frame for movement, the serious curtailment instrument and equipment longevity
Life, therefore prevents marine organisms fast-growth and adheres to significant.
The most anti-biological existing growth and sterilizing unit are broadly divided into two classes: a class is mechanical actuating mechanism,
As use under water wiper or scraper timing perform wiping action, will be attached to instrument surface bacterium and
Biology wipes out；Another kind of is chemistry medication, is thrown near waters, instrument place by human at periodic intervals
Containing the chemical agent of bio-toxicity, or instrument itself has and can slowly discharge the special of chemical agent
Device.
There is a lot of defect in the apparatus and method of the most anti-biological above-mentioned growth and sterilization, the office of mechanical device
Sex-limited include that the poor reliability of underwater movement executing agency, power consumption are high and be difficult to effectively protect geometry multiple
Miscellaneous sea sensor is the most spherical, cast etc. is irregularly shaped；The sterilization term of validity of chemistry medication is short also
And need constantly dispensing, and it is easily caused a series of problem of environmental pollution.
Summary of the invention
For the problem existing for the most anti-biological existing growth and sterilizing unit, the present invention releases under water
Ultraviolet sterilizer, its object is to by using the micro type ultra-violet of 260～280nm wave-length coverages to launch
Light source coordinates switching sequence controller and pressure watertight housings, and the ultraviolet radiation of generation is raw marine organisms
Long DNA clone and cell replication stages in early days, absorbed by the DNA base of cell, destroy eucaryotic cell structure
Stop cellular replication, prevent the bacterial biof iotalm absorption on oceanographic instrumentation surface and planktonic organism larva cell raw
Long, thus get rid of the high-grade marine organisms cell proliferations such as later stage algae, shellfish, finally make biological raw
Long and attachment is stagnated completely.

On circuit board.The light-emitting substrate on top is connected with switching sequence controller by lead-in wire, goes between from luminous base
Plate is drawn, after heat-conducting medium and insulator in the pressure watertight housings of lower end entrance connecting base also
Connecting valve time schedule controller.
Described pressure watertight housings bottom arranges cable sealed joint and power transmission line, and cable seal connects
Power transmission line is connected by head with the switching sequence controller on circuit board, and switching sequence controller is by external
Power convert is constant-current source, inputs to light-emitting substrate, and switching sequence controller controls luminescence-utraviolet two pole
Pipe is luminous at predetermined intervals.
Described switching sequence controller possesses the functions such as voltage conversion, constant current output and lighting timings control.
Switching sequence controller inputs to light-emitting substrate by being converted to constant current after external input power voltage stabilizing, and controls
Ultraviolet LED is the most luminous, predeterminable ultraviolet LED according to
Certain time interval circulation luminescence, fluorescent lifetime interval can arbitrarily be set to 5 points in units of 5 minutes
Clock, 10 minutes, 15 minutes ... 55 minutes.
The volume of ultraviolet sterilizer under water involved in the present invention is little, low in energy consumption, bactericidal effect is good, configuration
Flexibly and environment is not polluted, it is adaptable to protection lays for a long time, ambient water quality requires high, geometry
Complex-shaped sea sensor and oceanographic instrumentation, marine environmental monitoring early warning, marine ecology protection and
The numerous areas such as aquaculture have a good application prospect.
