Water inlet interface between adjacent two vertical baffles is connected by connecting tube 5 between pipe with vertically intaking, and the water inlet interface between adjacent two vertical baffles is with vertically water inlet pipe is just to setting, and connecting tube is vertically arranged.
The right-end openings of horizontal cylinder body, left end is closed, and the right-hand member of horizontal cylinder body is provided with bar through hole. Piston rod traverse bar through hole. The piston rod being positioned at the external side of horizontal cylinder is provided with ring baffle 78. Compression spring 77 it is provided with on piston rod and between ring baffle and horizontal cylinder body right-hand member. The end of piston rod is hinged with frizzen 711, and the jointed shaft 710 between piston rod and frizzen is horizontally disposed with, and the jointed shaft between piston rod and frizzen and piston rod axis perpendicular. The upper end of vertical baffle is provided with bar breach 61, and bar breach is oppositely arranged with piston rod. Turn left through the bar breach of adjacent upright baffle plate upper end in the end of frizzen. Frizzen is provided with shake-up fixture block 712.
As it is shown in figure 1, when buoyancy tube lower end is resisted against water acquisition cylinder inner bottom surface, the difference of the spacing of buoyancy tube upper surface extremely vertically water inlet pipe lower port and the axial length of cylindrical spool is more than the spacing between fuse guide rod upper end and piston rod axis.
As it is shown on figure 3, when the fixture block 712 that touches on frizzen is positioned at the right side of corresponding vertical baffle, and when touching bar gap edge that fixture block is resisted against corresponding vertical baffle, water inlet interface is between forward and backward two seals circle; When piston body is resisted against horizontal cylinder body left end, water inlet interface is positioned at the same side of forward and backward two seals circle.
As shown in Figure 1, Figure 3, when floating guide pin bushing is resisted against upper locating piece, vertical gag lever post is positioned at above ring baffle. The external diameter being smaller than ring baffle when floating guide pin bushing is resisted against lower locating piece, between vertical gag lever post lower end and piston rod axis. When the fixture block that touches on frizzen is positioned at the right side of corresponding vertical baffle, and when touching bar gap edge that fixture block is resisted against corresponding vertical baffle, vertical gag lever post is positioned at the left side of ring baffle, and vertically gag lever post near ring baffle.
The specific works process of the fixed point water acquisition equipment of the present embodiment is as follows:
First, as it is shown in figure 1, shake-up fixture block is resisted against the bar gap edge of corresponding vertical baffle before unmanned plane takes off, and shake-up fixture block is positioned at the right side of corresponding vertical baffle; Now, the vertically water inlet pipe of the water acquisition cylinder being positioned at the leftmost side is in opening, and the vertically water inlet pipe of all the other water acquisition cylinders is closed.
Second, drive automatic water sampling device to fly to the sampling marine site specified by unmanned plane.
3rd, by the pull rope of lowering or hoisting gear, automatic water sampling device is transferred on appointment sea. Will be floating across the sea by buoyant device after automatic water sampling device is positioned at sea, and sink in this process in sea water filtering cylinder mould, floating ring under the buoyancy of buoyant mass floating across the sea, thereby through on floating ring rinse hair to filter cylinder mould lateral surface clear up.
Then, pull rope continues to transfer, so that float plate moves down under gravity until floating guide pin bushing is resisted against on lower locating piece (as shown in Figure 1); Stop transferring followed by pull rope.
Meanwhile, as it is shown in figure 1, sea water by " the vertically water inlet pipe being in opening enters in corresponding water acquisition cylinder ", will constantly enter water acquisition cylinder along with sea water, under the buoyancy of buoyancy tube, buoyancy tube will drive fuse guide rod to float.
After buoyancy tube drive fuse guide rod floats a segment distance, drive cylindrical spool one is ibid moved. Then, buoyancy tube drives fuse guide rod and cylindrical spool to continue upper shifting, and by fuse guide rod by the up jack-up of the frizzen above it, breaks off relations so that touching fixture block; As shown in Figure 1, Figure 3, after touching fixture block unhook, move left together past to drive piston rod and piston body under the effect of compression spring, till ring baffle is resisted against on vertical gag lever post, thus avoiding piston body to open water inlet interface.
Followed by, buoyancy tube drives fuse guide rod and cylindrical spool to continue upper shifting, and make cylindrical spool near vertically water inlet pipe lower port, when cylindrical spool upper end and vertically between water inlet pipe lower port when being smaller than 2 millimeters, in annular under magnetic force and annular under suction between magnetic force, drive cylindrical spool is up moved by the lower magnetic force of annular, makes the upper end of cylindrical spool stretch into pipe of vertically intaking; Thus will vertically intake, pipe is closed, and completes the water sampling of this water acquisition cylinder, namely completes a water sampling.
4th, by the pull rope of lowering or hoisting gear, automatic water sampling device is up mentioned reset, in this process, first float plate is mentioned by pull rope, till floating guide pin bushing is resisted against upper locating piece; Then whole automatic water sampling device is up mentioned reset by pull rope.
When floating guide pin bushing is resisted against upper locating piece, vertical gag lever post will be located in above ring baffle; Now, the piston rod on the triggering device that fixture block breaks off relations and piston body are touched under the effect of compression spring, by continuation toward moving left, until piston body is resisted against horizontal cylinder body left end; Now water inlet interface is opened, so that the vertically water inlet pipe being positioned at the water acquisition cylinder of the adjacent right side of the water acquisition cylinder of water sampling is in opening, and the vertically water inlet pipe of all the other water acquisition cylinders is closed (namely after a water acquisition cylinder completes water sampling, by triggering the triggering device of the water acquisition cylinder of adjacent right side, the shake-up fixture block of this triggering device is made to break off relations; Thus after automatic water sampling device is up mentioned by pull rope, the vertically water inlet pipe of the water acquisition cylinder being positioned at the adjacent right side of the water acquisition cylinder of water sampling will be in opening).
On the other hand, together rise filtering the random frame of cylinder mould, moving in the process above sea gradually, floating ring is cleared up rinsing the hair lateral surface to filtering cylinder mould under gravity, it is to avoid water sampling next time is interfered by the attachment filtered on cylinder mould.
5th, return second step and continue operation, until after all of water acquisition cylinder all completes water sampling; Unmanned plane drives automatic water sampling device to make a return voyage. Thus the power consumption of the fixed point water acquisition equipment of the present embodiment is low, and different waters repeatedly can be pinpointed water sampling, thus being effectively improved sampling efficiency.
