The course of work of the power-actuated sediment pressurize of this hydrostatic pressing sampling thief is as follows:
1. sampling thief hangs down water by cable car on the ship, and sampling thief is freely falling body when the end off sea certain distance, sampling thief state (as shown in Figure 1).The lower surface of flow spool 39 is by following ring groove 44 in the upper piston rod 8, and lower through-hole 45 and following limbers 46 are communicated with low-pressure cavity; The upper surface of flow spool 39 is then by last center pit 36, last ring groove 60 links to each other with the high pressure sea water of last ring groove bottom opening 61 with overhead gage 65 tops, therefore flow spool 40 is in the smallest limit position under the high pressure sea water effect of upper surface, closed upper portion ring-shaped groove 40 is opened freeing port 43 simultaneously.The epicoele of driven plunger cylinder 49 is through lower baffle plate outlet pass 53, following water service pipe 56, lower annular recess 41, annular water-flowing trough 42 and freeing port 43 are communicated with low-pressure cavity, driven plunger cylinder 49 cavity of resorptions all are communicated with through piston cylinder freeing port 48 and low-pressure cavity and upper piston rod 8 equates with lower piston rod 28 sectional areas, on, bear pressure down and cancel out each other.Therefore, driven plunger 31 is in the bottom of driven plunger cylinder 49 under the self gravitation effect; Sliding plunger 27 is in the bottom of impact piston cylinder 13 under the self gravitation effect is supported by piston stopper 25.Claw 3 closes up and tightly hoist block 2 is blocked, and bears the weight of sampling thief together, and wirerope 9 is in relaxed state.Outstanding spring thimble 68 snaps in the semilune groove on the stopple coupon 20, and the weight of bearing stopple coupon 20 prevents that stopple coupon 20 from deviating from.Movable flip 18 is erected at a side of pressurize tube 23 inwalls, and sampled pipe 20 outer walls block.Retaining valve 12 is closed, and extraneous seawater can not enter the low-pressure cavity of impacting in the tube 7.
2. sampling thief inserts the sediment certain depth under the self gravitation effect, after stopping, and following ring groove 44 during the upper surface of flow spool 39 is passed through, last limbers 37, last through hole 38 is communicated with low-pressure cavity; Go up ring groove bottom opening 58 during flow spool 39 lower surfaces are passed through, in go up ring groove 57, following center pit 51, following ring groove bottom opening 47, following ring groove 50 is communicated with the high pressure sea water of overhead gage 65 tops.Flow spool 39 is in the limes superiors position under the high pressure of lower surface, open upper, annular groove 40, closes freeing port 43.Extraneous high pressure sea water process overhead gage outlet pass 64, last water service pipe 59, upper, annular groove 40, lower annular recess 41, following water service pipe 56 and lower baffle plate outlet pass 53 enter driven plunger cylinder 49 epicoeles, promote driven plunger 31 motions, with impact part jack-up.Impact part rising certain altitude, piston stopper 25 is blocked by sliding plunger 27; Impact part continues to move upward together with sliding plunger 27; Spring detent 72 and stopple coupon piston stopper 67 disengage and move upward, until stopping.
When impact part rose to the limes superiors position, the lower surface of flow spool 39 was by following ring groove 44 in the upper piston rod 8, and lower through-hole 45 and following limbers 46 are communicated with low-pressure cavity; The upper surface of flow spool 39 is then by last center pit 36, last ring groove 60 links to each other with the high pressure sea water of last ring groove bottom opening 61 with overhead gage 65 tops, therefore flow spool 40 is in the smallest limit position under the high pressure sea water effect of upper surface, closed upper portion ring-shaped groove 40 is opened freeing port 43 simultaneously.The seawater process lower baffle plate outlet pass 53 of the epicoele of driven plunger cylinder 49, following water service pipe 56, lower annular recess 41, annular water-flowing trough 42 and freeing port 43 flow to low-pressure cavity; Driven plunger cylinder 49 cavity of resorptions all are communicated with through piston cylinder freeing port 48 and low-pressure cavity.Impact part fall to hit stopple coupon 20, makes stopple coupon 20 insert the sediment certain depths and stops.A vibration sampling one way finishes thus, and sampling thief repeats this one way, reaches balance up to low-pressure cavity maritime interior waters pressure and extraneous seawater pressure.After sampling thief the end, hoist block 2 was because the relative claw 3 of inertia moves downward a little, and claw 3 opens, and lifting hawser 1 is lax, and hoist block 2 is owing to deadweight drops on the master jaw 35.
3. the sampling thief sampling finishes, and equipment reclaims.Lifting hawser 1 pulling hoist block 2 and wirerope 9 promotes sampling thief.Wirerope 9 utilizes the step of stopple coupon piston 17 to open spring detent 72 when promoting, and drives stopple coupon piston stopper 67, dividing plate 71, and sleeve 69, stopple coupon 20 rises.Under the pulling of wirerope 9, the small cylinder of stopple coupon piston 17 heads utilizes the pretightning force of the weight generation of sampling thief as sealing, and fills in end cap central bore 66, finishes sealing by the distortion of O RunddichtringO.Stopple coupon 20 is drawn in the guide cylinder 15 and movable flip 18 disengages, the elastic force of jump ring makes movable flip 18 overturnings, as guiding, fill in the center pit of pressurize tube bottom end cover 22 with the tapering inclined-plane of pressurize tube bottom end cover 22 smoothly, finish sealing by the distortion of O RunddichtringO.
At this moment, the seawater pressure in the low-pressure cavity is than the pressure height of outside seawater, and the lower surface of flow spool 39 is by following ring groove 44 in the upper piston rod 8, and lower through-hole 45 and following limbers 46 are communicated with low-pressure cavity; The upper surface of flow spool 39 is then by last center pit 36, last ring groove 60 links to each other with the seawater of last ring groove bottom opening 61 with overhead gage 65 tops, therefore flow spool 40 is in the smallest limit position under the high pressure sea water effect of upper surface, and closed upper portion ring-shaped groove 40 is opened freeing port 43 simultaneously.The epicoele process lower baffle plate outlet pass 53 of driven plunger cylinder 49, following water service pipe 56, lower annular recess 41, annular water-flowing trough 42 and freeing port 43 are communicated with low-pressure cavity; Driven plunger cylinder 49 cavity of resorptions all are communicated with through piston cylinder freeing port 48 and low-pressure cavity; High pressure sea water in the whole low-pressure cavity is sealed.The high pressure sea water and the leather bag 6 that impact low-pressure cavity in the tube 7 constitute " accumulator "; The ftercompction seawater passes through to impact a tube osculum 10, retaining valve 10, and flexible pipe 12 and ftercompction hole 16 flow to pressurize tube 23, and sample is carried out pressurize.
