As shown in Figure 2 and Figure 3, when main support rod is in vertical state, and when radially-directed hole and casing limit hole are positioned at sustained height, trigger Extensible formula buffering umbrella is in contraction state, and namely umbrella cover shrinks.
As shown in Figure 2, Figure 4 shows, when main support rod is in vertical state, and when triggering counterweight is vertically suspended on below frizzen by fuse rope: under the Action of Gravity Field triggering counterweight, frizzen will move down and be resisted against on interior positive stop.
As shown in Figure 4, when the lower end of frizzen is positioned at below radially-directed hole, and when the inner of radial pin is resisted against on frizzen lateral surface, the outer end of radial pin is positioned at casing limit hole.
The specific works process of the seabed water sample depth sampler of the present embodiment is as follows:
The first, by traction rope, anti-interference collecting device is sling, and make main support rod be in vertical state;
Then, sliding sleeve is moved down, and make radially-directed hole and casing limit hole be positioned at sustained height, thus make trigger Extensible formula cushion umbrella contraction;
Again then, by bracing wire, radial pin is pulled out, and make radial pin outer end be positioned at casing limit hole (because radially-directed hole and casing limit hole are positioned at the below of secondary umbrella frame, like this can handled easily person by bracing wire, radial pin is pulled out); Make frizzen simultaneously under the Action of Gravity Field triggering counterweight, move down and be resisted against on interior positive stop; Finally, bracing wire is discharged.Now, as shown in Figure 2, Figure 4 shows, the outer end of radial pin is positioned at casing limit hole, prevents from sliding sleeve moves, thus prevents trigger Extensible formula buffering umbrella from opening.
The second, by traction rope, seabed water sample depth sampler is put into water, then allow traction rope go out in the gravity extension of anti-interference collecting device; In this process, trigger counterweight and will contact seabed at first; After triggering counterweight is resisted against seabed, under the effect of extension spring, frizzen moves.When above frizzen is positioned at radial pin, under the effect of pretension Compress Spring, radial pin will move to toward in radially-directed hole; Now under flow action, umbrella cover will open, and till the upper end of sliding sleeve is resisted against on outer positive stop, now trigger Extensible formula buffering umbrella is in open mode.After trigger Extensible formula buffering umbrella is in and opens, the lower settling velocity of trigger Extensible formula weight-driven sharply reduces, under the effect of buoyant device, the lower settling velocity of hydrophore also will reduce gradually simultaneously, thus effectively can reduce the impulsive force that trigger Extensible formula weight-driven clashes into seabed, make the seabed interaction that trigger Extensible formula weight-driven is mild; Thus can effectively solve because can slime water be evoked when weight touches the end, and impact gather the problem of the quality of water sample.
3rd, after anti-interference heavy hammer mechanism sinks to seabed, supported by feet, anti-interference heavy hammer mechanism can be avoided further to the stirring in seabed; Under the effect of buoyant device, hydrophore will be suspended in above seabed simultaneously, thus roughly can be determined the position of hydrophore by the length of connection cord; And then can ensure that the seawater gathered is the bottom seawater of set depth.
4th, by traction rope, seabed water sample depth sampler is mentioned.
