The external diameter of plate.When the shake-up fixture block on frizzen is located at the right side of corresponding vertical baffle, and touch fixture block be resisted against it is corresponding perpendicular
During the bar gap edge of straight baffle plate, vertical gag lever post is located at the left side of ring baffle, and vertical gag lever post is close to ring baffle.
The specific work process of the floatation type top layer water-sampling device of the present embodiment is as follows：
First, as shown in figure 1, before unmanned plane takes off：Position of the scaffold on vertical guide rod is adjusted, and passes through clamp screw
Scaffold guide pin bushing is fixed on vertical guide rod by bolt；Position by adjusting scaffold can be adjusted in the range of certain depth of water adopts automatically
The water acquisition depth of water installations.
Meanwhile fixture block will be touched and be resisted against the bar gap edge of corresponding vertical baffle, and fixture block is touched positioned at corresponding
The right side of vertical baffle；Now, the vertical water inlet pipe positioned at the water acquisition cylinder of the leftmost side is in opening, and remaining water acquisition cylinder
Vertical water inlet pipe be closed.
Second, drive automatic water sampling device to fly to specified sampling marine site by unmanned plane.
3rd, frame and automatic water sampling device are transferred on specified sea by the pull rope of lowering or hoisting gear.Work as frame
And after automatic water sampling device is located at sea, buoyant device and scaffold will float across the sea；And sink to seawater in filtering cylinder mould
During this interior, floating ring floats across the sea under the buoyancy of buoyant mass, so as to by rinsing hair on floating ring
The lateral surface for filtering cylinder mould is cleared up.
Then, pull rope continues to transfer, and vertical guide rod and automatic water sampling device will continue to move down in this process,
Until scaffold guide pin bushing against untill on locating piece on first, vertical guide rod and automatic water sampling device stop moving down；In this process
In, as shown in figure 1, seawater will be by " corresponding to the vertical water inlet pipe entrance in opening in water acquisition cylinder ", with sea
Water constantly enters water acquisition cylinder；Thus the water acquisition cylinder of this programme can continuously gather the water in the range of water surface depth below
Sample.Followed by pull rope continues to transfer, so that float plate moves down under gravity until floating guide pin bushing is resisted against down
On locating piece（As shown in Figure 1）, then pull rope stopping decentralization.
As shown in figure 1, as seawater constantly enters water acquisition cylinder, buoyancy tube draws drive under the buoyancy of buoyancy tube
Believe that guide rod floats.After buoyancy tube drives fuse guide rod one segment distance of floating cylindrical spool will be driven together to move up.Then, buoyancy
Cylinder drive fuse guide rod and cylindrical spool continue to move up, and are up jacked up the frizzen above it by fuse guide rod, so as to
Shake-up fixture block is set to break off relations；As shown in Figure 1, Figure 3, after fixture block unhook is touched, piston rod will be driven in the presence of compression spring
And piston body is together toward moving left, untill ring baffle is resisted against on vertical gag lever post, so as to avoid piston body open into
Water interface.
Followed by buoyancy tube drives fuse guide rod and cylindrical spool to continue to move up, and makes cylindrical spool close to vertical water inlet
Pipe lower port, when between the upper end of cylindrical spool and vertical water inlet pipe lower port when being smaller than 2 millimeters, in annular
Under suction between magnetic force and the lower magnetic force of annular, the lower magnetic force of annular will drive cylindrical spool up to move, and make cylindrical spool
Upper end stretch into vertical water inlet pipe；So as to the pipe closing that will intake vertically, the water sampling of the water acquisition cylinder is completed, that is, completes one
Secondary water sampling.
4th, automatic water sampling device is up lifted by reset by the pull rope of lowering or hoisting gear, in this process, traction
Rope first lifts float plate, untill floating guide pin bushing is resisted against first time locating piece；Then pull rope will be adopted entirely automatically
Water installations up lift reset.
When floating guide pin bushing is resisted against first time locating piece, vertical gag lever post will be located above ring baffle；Now, touch
Piston rod and piston body on the trigger device of fixture block unhook will continue toward moving left, until living in the presence of compression spring
Cock body is resisted against horizontal cylinder body left end；Now water inlet interface is opened, so that positioned at the adjacent of the water acquisition cylinder for completing water sampling
The vertical water inlet pipe of the water acquisition cylinder on right side is in opening, and the vertical water inlet pipe of remaining water acquisition cylinder is closed
（I.e. after a water acquisition cylinder completes water sampling, the trigger device of the water acquisition cylinder of adjacent right side will be triggered, makes the trigger device
Fixture block is touched to break off relations；Thus after pull rope up lifts automatic water sampling device, positioned at the water acquisition cylinder for completing water sampling
The vertical water inlet pipe of the water acquisition cylinder of adjacent right side will be in opening）.
On the other hand, together rise in the filtering random frame of cylinder mould, during gradually moving to above sea, floating ring is in weight
Hair will be rinsed under power effect to clear up the lateral surface for filtering cylinder mould, avoids filtering the attachment on cylinder mould to water sample next time
Collection interferes.
5th, return to second step and continue to operate, until after all water acquisition cylinders all complete water sampling；Unmanned plane drives certainly
Dynamic water sampling device makes a return voyage.Thus the power consumption of the floatation type top layer water-sampling device of the present embodiment is low, and different waters can be entered
Row repeatedly fixed point water sampling, so as to effectively improve sampling efficiency.
