The specific works process of the surface seawater multipoint mode collecting device of the present embodiment is as follows:
The first, as shown in Figure 2, before unmanned plane takes off, the shake-up fixture block on frizzen is resisted against and dodges gap edge accordingly, and lower limit projection is resisted against on annular spacing block set.
The second, drive the flight of surface seawater multipoint mode collecting device to the sampling marine site of specifying by unmanned plane, then locate the height of unmanned plane according to distance measuring equipment, the spacing namely between unmanned plane and the water surface.
3rd, the clutch coupling that controller controls one of them automatic water sampling device closes, and the clutch coupling of all the other two automatic water sampling devices disconnects.
4th, drive motor drives the 3rd axostylus axostyle and driving gear to rotate, and then the reel that band dynamic clutch is in the automatic water sampling device of closure state rotates, thus this automatic water sampling device is adopted water drum and transfer to and specify in marine site.
Transfer to specify behind marine site when adopting water drum, adopt water drum across the sea floating by buoyant mass, meanwhile, seawater is entered by circular hole of intaking to be adopted in water drum; Adopt water drum along with seawater constantly enters, under the buoyancy of buoyancy tube, buoyancy tube will drive fuse guide rod to float; Then, buoyancy tube drives in fuse guide rod and cylindrical spool continuation and moves, and make cylindrical spool near water inlet circular hole lower port, when spacing between the upper end and water inlet circular hole lower port of cylindrical spool is less than 2 millimeters, under suction in annular between magnetic force and annular lower magnetic force, drive cylindrical spool up moves by annular lower magnetic force, makes the upper end of cylindrical spool stretch into into water circular hole; Thus circular hole of intaking is closed, and completes the water sampling that this adopts water drum, namely completes a water sampling.
5th, controller drives reel to rotate by drive motor, thus the water drum of adopting completing water sampling is up mentioned reset.In this process, fill seawater owing to adopting in water drum, buoyancy tube drives fuse guide rod to float, thus spacing block set is resisted against after on annular spacing block set instantly, trigger dull and stereotyped by frizzen up jack-up, thus shake-up fixture block is broken off relations, and triggering flat board will be pressed on trigger sensor.
After shake-up fixture block breaks off relations, under the effect of pretension Compress Spring, make horizontal pin stretch in vertical spacing guide pin bushing, until outer limited block is resisted against in vertical back up pad, now, the end of horizontal pin is stretched in vertical spacing guide pin bushing and is coordinated with lower limit projection, adopt water drum for spacing, prevent the water drum of adopting of water sampling from dropping.
When triggering flat board and being pressed on trigger sensor, controller sends instruction has made the clutch coupling of the automatic water sampling device of water sampling disconnect, and a clutch coupling not carrying out the automatic water sampling device of water sampling is closed (only having a clutch coupling not carrying out the automatic water sampling device of water sampling to close).
6th, return the 4th step and continue operation, until after all automatic water sampling devices complete water sampling; Unmanned plane makes a return voyage.Thus the surface seawater multipoint mode collecting device of the present embodiment repeatedly can be fixed a point water sampling to different waters, thus effectively improves sampling efficiency.
