Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of triggering expanded type weight-driven includes main support rod 11, the triggering on main support rod is arranged on
Expanded type buffers umbrella, triggering device and main counterweight 12.Main counterweight is located at below triggering expanded type buffering umbrella.Main counterweight is in cylinder
Shape, and in the lower surface of main counterweight and the lower surface of main support rod be generally aligned in the same plane.It is provided with main support rod and runs through main support
Longitudinal axis hole of bar both ends of the surface.Longitudinal axis hole is coaxially disposed with main support rod.The upper end of main support rod is provided with connection ring.
Triggering expanded type buffering pack includes the slidable sliding sleeve 15 being set on main support rod, some around main support rod week
To uniform main umbrella skeleton 18, the one-to-one secondary umbrella frame 16 of some and main umbrella skeleton and the umbrella cover being arranged on main umbrella skeleton.This implementation
The length of main support rod is 0.5 meter in example.Umbrella cover is located above main umbrella skeleton, and each main umbrella skeleton is connected with umbrella cover.Main umbrella skeleton
Upper end is hinged 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；
I.e. secondary umbrella frame upper end is hinged on sliding sleeve, and lower end is hinged in the middle part of corresponding main umbrella skeleton.On main support rod lateral surface and positioned at cunning
Set top is provided with outer positive stop 17, and when the upper end of sliding sleeve is against on outer positive stop, triggering expanded type buffering umbrella
In open mode（I.e. secondary umbrella frame and main umbrella skeleton are by umbrella cover）.
As shown in Figure 1, Figure 2, Figure 3 shows, triggering device includes triggering counterweight 14, and bracing wire 112 is arranged on the outside of main support rod
Middle face and the radially-directed hole being connected with longitudinal axis hole, are slidably arranged on the radial direction pin 111 in laterally steering hole, if
The interior positive stop 116 on longitudinal axis hole medial surface and below radially-directed hole is put, longitudinal axis hole is slidably arranged on
Frizzen 19 interior and above interior positive stop, is arranged on the connector in longitudinal axis hole and being located above frizzen and sets
Put in longitudinal axis hole and positioned at the extension spring 110 between frizzen and connector.The upper end of extension spring is connected with connector, extension spring
Lower end be connected with frizzen upper end.Radially-directed hole is radially extended along longitudinal axis hole.Close to main support rod lateral surface
The medial surface in radially-directed hole is provided with outer annular spacing block set 113.On the radial direction pin lateral surface at longitudinal direction axis hole center
Provided with annular spacing block set 115.Pretension compression spring is arranged with radial direction pin and between inside and outside annular spacing block set
114.One end of bracing wire is connected with the outer end of radial direction pin.Triggering device is spherical in shape.Counterweight is triggered to be located at below main support rod.
The volume of counterweight is triggered less than the 1/10 of the volume of main counterweight.Triggering counterweight is connected by fuse rope 13 with the lower end of frizzen
Connect.The lower end of fuse rope is connected with triggering counterweight, and the upper end of fuse rope is stretched into longitudinal axis hole by the lower port of longitudinal axis hole
And be connected with the lower end of frizzen.
As shown in Figure 1 and Figure 2, when sliding sleeve is located at the lower section in radially-directed hole, triggering expanded type buffering umbrella is in contraction-like
State, i.e. umbrella cover are shunk.
As shown in Figure 1, Figure 3, when main support rod be in vertical state, and triggering counterweight be suspended on vertically by fuse rope it is tactile
When sending out below bar：Under the Action of Gravity Field of 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 located at below radially-directed hole, and the inner of radial direction pin is resisted against triggering
When on bar lateral surface, the outer end of radial direction pin is located at the outside in radially-directed hole.
The concrete application process of the triggering expanded type weight-driven of the present embodiment is as follows：
As shown in figure 4, the upper end of main support rod is connected by connecting rope 5 with the lower end of hydrophore 4.The upper end of hydrophore
Connect pull rope 2.Pull rope is provided with buoyant device 3.Hydrophore is prior art.The buoyancy of buoyant device be more than hydrophore and
The gravity sum of buoyant device, and less than hydrophore, buoyant device and the gravity sum for triggering expanded type weight-driven.
Specific water sampling process is as follows：
First, as shown in figure 4, hydrophore and triggering expanded type weight-driven is sling by pull rope, and make main support
Bar is in vertical state；Then, sliding sleeve is moved to the lower section in radially-directed hole, so that triggering expanded type buffering umbrella shrinks；Again
Then radial direction pin is pulled out by bracing wire, and makes frizzen under the Action of Gravity Field of triggering counterweight, moved 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 direction pin is located at the outside in radially-directed hole, anti-for spacing sliding sleeve
Anti-skid sheath is moved up, so as to prevent triggering expanded type buffering umbrella from opening.
Second, it is put into by pull rope by expanded type weight-driven is triggered in water, then allows pull rope in weight-driven
Gravity extension goes out；In this process, triggering counterweight will contact seabed at first；After triggering counterweight is resisted against seabed,
Frizzen is moved up in the presence of extension spring.When frizzen is located above radial direction pin, in the presence of pretension compression spring radially
Pin will be moved in radially-directed hole inside；Now under flow action, umbrella cover will open, until the upper end of sliding sleeve is resisted against
Untill on outer positive stop, now trigger expanded type buffering umbrella and be in open mode.Opened when triggering expanded type buffering umbrella is in
Afterwards, triggering expanded type weight-driven lower sinking speed drastically reduce, while in the presence of buoyant device hydrophore sinking
Reduction of speed degree also will be reduced gradually, thus can effectively reduce the impulsive force that triggering expanded type weight-driven hits seabed, make triggering
Expanded type weight-driven is gentle to be contacted with seabed；So as to effectively solve because weight is bottomed out when can evoke slime water, and influence
The problem of gathered water sample quality.
3rd, after triggering expanded type weight-driven sinks to seabed, hydrophore will suspend in the presence of buoyant device
Above seabed, thus the position of hydrophore can substantially be determined by the length of connecting rope；And then can guarantee that what is gathered
Seawater is the bottom seawater of set depth.
4th, lifted by pull rope by expanded type weight-driven is triggered.
