Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
As shown in Figure 1, a kind of trigger Extensible formula weight-driven comprises main support rod 11, is arranged on trigger Extensible formula buffering umbrella, flip flop equipment and main counterweight 12 on main support rod.Main counterweight is positioned at below trigger Extensible formula buffering umbrella.Main counterweight is cylindric, and the lower surface of main counterweight and the lower surface of main support rod are positioned at same plane.The longitudinal axis hole running through main support rod both ends of the surface is provided with in main support rod.Longitudinal axis hole and main support rod are coaxially arranged.The upper end of main support rod is provided with abutment ring.
The sliding sleeve 15 be slidably set on main support rod drawn together by trigger Extensible formula buffering pack, some around the uniform main umbrella skeleton 18 of main support rod circumference, some with main umbrella skeleton secondary umbrella frame 16 and the umbrella cover that is arranged on main umbrella skeleton one to one.In the present embodiment, the length of main support rod is 0.5 meter.Umbrella cover is positioned at above main umbrella skeleton, and each main umbrella skeleton is connected with umbrella cover.The upper end thereof of main umbrella skeleton is on the top of main support rod.Secondary umbrella frame one end is hinged on sliding sleeve, and the other end is hinged in the middle part of corresponding main umbrella skeleton; Namely secondary umbrella frame upper end thereof is on sliding sleeve, and lower end is hinged in the middle part of corresponding main umbrella skeleton.Main support rod lateral surface is positioned at above sliding sleeve and is provided with outer positive stop 17, and when the upper end of sliding sleeve is resisted against on outer positive stop, trigger Extensible formula buffering umbrella is in open mode (namely secondary umbrella frame and main umbrella skeleton are by umbrella cover).
As Fig. 1, Fig. 2, shown in Fig. 3, flip flop equipment comprises triggering counterweight 14, bracing wire 112, in the middle part of the lateral surface being arranged on main support rod and the radially-directed hole be connected with longitudinal axis hole, slidably be arranged on the radial pin 111 in laterally steering hole, to be arranged on longitudinal axis hole medial surface and the positive stop 116 be positioned at below radially-directed hole, slidably to be arranged in longitudinal axis hole and the frizzen 19 be positioned at above positive stop, to be arranged in longitudinal axis hole and web member above frizzen and being arranged in longitudinal axis hole and extension spring 110 between frizzen and web member.The upper end of extension spring is connected with web member, and the lower end of extension spring is connected with frizzen upper end.Radially-directed hole longitudinally axis hole radial direction extend.Medial surface near the radially-directed hole of main support rod lateral surface is provided with outer ring spacing block set 113.Radial pin lateral surface near longitudinal axis hole center is provided with interior annular spacing block set 115.Radial pin is arranged with pretension Compress Spring 114 between inside and outside annular spacing block set.One end of bracing wire is connected with the outer end of radial pin.Flip flop equipment is spherical in shape.Trigger counterweight to be positioned at below main support rod.The volume triggering counterweight is less than 1/10 of the volume of main counterweight.Trigger counterweight to be connected with the lower end of frizzen by fuse rope 13.The lower end of fuse rope is connected with triggering counterweight, and the upper end of fuse rope is stretched in longitudinal axis hole and with the lower end of frizzen by the lower port of longitudinal axis hole and is connected.
As shown in Figure 1 and Figure 2, when sliding sleeve is positioned at the below in radially-directed hole, trigger Extensible formula buffering umbrella is in contraction state, and namely umbrella cover shrinks.
As shown in Figure 1, Figure 3, 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 3, 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 the outside in radially-directed hole.
The embody rule process of the trigger Extensible formula weight-driven of the present embodiment is as follows:
As shown in Figure 4, the upper end of main support rod is connected by the lower end of connection cord 5 with hydrophore 4.The upper end of hydrophore connects traction rope 2.Traction rope is provided with buoyant device 3.Hydrophore is prior art.The buoyancy of buoyant device is greater than the gravity sum of hydrophore and buoyant device, and is less than the gravity sum of hydrophore, buoyant device and trigger Extensible formula weight-driven.
Concrete water sampling process is as follows:
The first, as shown in Figure 4, by traction rope, hydrophore and trigger Extensible formula weight-driven are sling, and make main support rod be in vertical state; Then, sliding sleeve is moved to the below in radially-directed hole, thus make trigger Extensible formula cushion umbrella contraction; Then by bracing wire, radial pin is pulled out again, and make frizzen 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 1, Figure 3, the outer end of radial pin is positioned at the outside in radially-directed hole, moves on the anti-anti-skid sheath of spacing sliding sleeve, thus prevents trigger Extensible formula buffering umbrella from opening.
The second, by traction rope, trigger Extensible formula weight-driven is put into water, then allow traction rope go out in the gravity extension of weight-driven; 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 water sample quality.
3rd, after trigger Extensible formula weight-driven sinks to seabed, under the effect of buoyant device, hydrophore will be suspended in above seabed, 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, trigger Extensible formula weight-driven is mentioned.
