Description
Technical field
The present invention relates to a kind of shallow sea water storm deposit field observation sampler, for the field observation of shallow sea water storm tide (or extreme wind weather) effect lower seabed storm deposit process and the sampling work of storm deposit thing undisturbed.
Background technology
Storm tide is as a kind of common extreme accident of nature, great impact is had on the evolved stages of Coastal Zone Terrain landforms, to the change of shallow sea water sedimentary environment clearly, therefore observation is carried out with taking a sample to research to the storm deposit of shallow sea water and there is important scientific meaning.
Due to storm tide occur time, weather environment is severe, the wave is high greatly for sea turn, the field observation of storm deposit is more difficult, studies so deliver to laboratory again after mainly obtaining sediment sample with box corer or coring apparatus after storm tide occurs to the research of storm deposit at present it.But there is many defects in traditional storm deposit sampling method: first, soft, the full water of oceanic sediment, traditional box corer or coring apparatus easily become disturbance to sediment bedding structure and compress sediment sample in sampling process; Secondly, owing to being sampling after storm tide occurs, not easily observe storm sedimentary body with under cover sedimental interphase, more cannot to know when storm occurs seawater to the disturbance of deposit surface and scour depth.These Problems existing have impact on the precision of storm deposit sampling to a great extent, cannot meet the requirement of follow-up study, bring very large difficulty to the scrutiny of offshore storm deposit.
Simultaneously, deposition process during storm tide is very complicated, this traditional research method lacks the direct observation to storm deposit process, indirectly can only infer this process from obtained sample characteristic, cause people still not enough to the scientific knowledge of shallow sea water storm deposit process at present.So, if field observation can be carried out to the near-bottom current under storm surge action, wave, outstanding husky amount, seafloor scour and deposition process while sampling, understand local sedimental starting in a storm processes, suspension, storm water body carries the sedimentation alluvial of silt, and water body is to the detailed process such as to wash away of storm deposit after storm tide, studying storm deposit for us has very important meaning.
Therefore, design a kind of mesolittoral zone storm deposit thing in-situ sampling device easy and simple to handle, improving the sampling precision to storm sedimentary body and the field observation that can realize seabed storm deposit process, is technical matters urgently to be resolved hurrily.
Summary of the invention
The object of this invention is to provide a kind of shallow sea water storm deposit field observation sampler, to fill up the blank that current shallow sea water does not have storm deposit field observation sampler.
A kind of shallow sea water storm deposit field observation sampler, it is characterized in that this device comprises sampling dish, sampling dish bottom is provided with three spud piles device being fixed on seabed, sampling dish is arranged seal groove and support, by retainer plate fixed roof on support, motor and screw propulsion rod are installed above top cover, turbidimeter is installed in support both sides, laser range finder, pressure transducer and current meter, respectively to the water turbidity during storm deposit research, thickness of deposits, wave pressure and ocean current change in flow feature carry out field observation, device is also provided with single-chip microcomputer and battery compartment in addition.
Device can firmly insert in marine bottom sediment by described three spud piles, ensures the stability of device between observation and sampling date, and can carry out dismounting with sampling dish easily, is beneficial to stablizing when device transports.
Described sampling dish is disc-shaped structure, and edge arranges seal groove, is mainly used in accepting storm deposit in storm tide process.
Described top cover significant height 10cm, automatically can move downward until connect with seal groove by the motor and screw propulsion rod being arranged on top after sampling terminates, the sediment sample that sampling dish is collected and its overlying water are closed, and keeps the virgin state of storm deposit as much as possible.
Described top cover is transparent organic glass material, is convenient to observe the sedimentary state in sampler; There is a suction eye above it, when being convenient to laboratory experiment, the water body in device is extracted out.
Described turbidimeter experimentally object and requirement can carry out the mensuration of water turbidity on horizontal or vertical direction, and this index can be used to the relative concentration characterizing Suspended Sediment.
The measuring accuracy of described laser range finder is 1mm, can accurately measure, the change of marine bottom sediment erosion and alluvial in record storm tide process to the thickness of deposits change in vertical direction.
Described pressure transducer and current meter, can measure storm tide process Wave pressure and ocean current change in flow feature, and these two hydrodynamic parameters obtained analyze sediment in storm tide process to start, suspend and the important indicator of sedimentation.
Described single-chip microcomputer can be arranged the time interval that turbidimeter, laser range finder, pressure transducer and current meter are measured.
Said apparatus is utilized to carry out the field observation of shallow sea water storm tide (or extreme wind weather) effect lower seabed storm deposit process and the sampling work of storm deposit thing undisturbed, it is characterized in that this device is fixed on sampling erect-position before storm tide occurs, in storm tide generating process, seabed storm deposit process is carried out to field observation and accepted storm deposit, can complete preservation storm deposit original state sample after storm tide, can in laboratory to gathered sample and data analysis after device reclaims by researchist, research seabed storm deposit process.
Obviously, the present invention is rational in infrastructure, easy to operate, be applicable to the field observation of shallow sea water storm tide (or extreme wind weather) effect lower seabed storm deposit process and the sampling work of storm deposit thing undisturbed, compared with the column of traditional storm deposit or box sampling method, having can high, convenient and safe, the automaticity advantages of higher of simultaneous observation storm deposit process, the little precision of storm deposit sampling disturbance.
When the present invention uses, the parameters such as the time interval observed by the beginning and ending time of setting device work, each equipment, can be implemented in the sampling work in specified sea areas, special time period, the near-bottom current under storm surge action, wave, outstanding husky amount, seafloor scour and deposition process being carried out to field observation and sediment undisturbed, effectively can solve traditional research method and lack the problem such as field observation, the disturbance of sediment undisturbed; In addition, this plant automation degree is high, can realize the field observation under strong wind process and sampling work under strong wind weather, severe sea condition condition, effectively avoid people and boats and ships under severe conditions marine Continuous Observation, sampling exist danger.The present invention has very important meaning for the process study of shallow sea water storm deposit.
