First, as shown in figure 1, shake-up fixture block to be resisted against to the bar breach of corresponding vertical baffle before unmanned plane takes off
Edge, and touch the right side that fixture block is located at corresponding vertical baffle；Now, at the vertical water inlet pipe of the water acquisition cylinder of the leftmost side
In opening, and the vertical water inlet pipe of remaining water acquisition cylinder is closed.
Second, drive automatic water sampling device to fly to specified sampling marine site by unmanned plane.
3rd, automatic water sampling device is transferred on specified sea by the pull rope of lowering or hoisting gear.When automatic water acquisition fills
Setting in behind sea will by buoyant device float across the sea, and filtering cylinder mould sink to this in seawater during,
Floating ring floats across the sea under the buoyancy of buoyant mass, so as to by rinsing outside of the hair to filtering cylinder mould on floating ring
Face is cleared up.
Then, pull rope continues to transfer so that float plate move down under gravity until floating guide pin bushing against
On lower locating piece（As shown in Figure 1）；Stop transferring followed by pull rope.
Meanwhile as shown in figure 1, seawater will pass through " water acquisition cylinder corresponding to the vertical water inlet pipe entrance in opening
It is interior ", as seawater constantly enters water acquisition cylinder, buoyancy tube will drive fuse guide rod to float under the buoyancy of buoyancy tube.
After buoyancy tube drives fuse guide rod one segment distance of floating cylindrical spool will be driven together to move up.Then, buoyancy tube
Drive fuse guide rod and cylindrical spool to continue to move up, and up jacked up the frizzen above it by fuse guide rod, so that
Fixture block is touched to break off relations；As shown in Figure 1, Figure 3, when touch fixture block break off relations after, in the presence of compression spring will drive piston rod 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 from opening water inlet
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 upper locating piece；Then pull rope entirely automatic water acquisition will fill
Put and up lift reset.
When floating guide pin bushing is resisted against upper locating piece, vertical gag lever post will be located above ring baffle；Now, fixture block is touched
Piston rod and piston body on the trigger device of unhook will continue toward moving left, until piston body in the presence of compression spring
It is resisted against horizontal cylinder body left end；Now water inlet interface is opened, so that the adjacent right side positioned at the water acquisition cylinder for completing water sampling
The vertical water inlet pipe of water acquisition cylinder be 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 touching for the trigger device
Dynamic fixture block breaks off relations；Thus after pull rope up lifts automatic water sampling device, positioned at the phase for the water acquisition cylinder for completing water sampling
The vertical water inlet pipe of the water acquisition cylinder on 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 fixed point water acquisition equipment of the present embodiment is low, and different waters can be carried out repeatedly to determine
Point water sampling, so as to effectively improve sampling efficiency.
