The invention has the beneficial effects as follows: the present invention adopts cam structure corresponding one by one with d/d push rod the different angles position of motor shaft, equips releasable requirement to satisfy the deep-sea.The present invention adopts the frame mode of transition rod transmission in addition, has strengthened the reliability of releasing mechanism, and the layout type of circumference array has guaranteed that also this device has higher space availability ratio simultaneously.This sampling valve driver train has that volume is little, little power consumption, easy to use, advantage such as can be repeatedly used, be fit to very much the deep-sea and use.It not only is suitable for the release of deep-sea sequential sampling device, also is applicable to the release of most of underwater kit under the different depth of waters.
Description of drawings
Fig. 1 is the release gear structure cutaway view for the deep-sea;
Fig. 2 is the scheme drawing of cam structure;
Among the figure: housing 1, baffle plate end cap 2, main shaft 3, cam 4, push rod 5, transition rod 6, push rod stop collar 7, push rod spring cover 8, spring 9, tightening key 10, main shaft end cap 11, bolt 12, nut 13, motor fixing plate frame 14, motor 15, motor cavity urceolus 16, oil sac 17, end cap 18, through hole 19, watertight line interface 20, O shape circle 21.
The specific embodiment
Further specify the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, sampling valve linear drive apparatus for the deep-sea of the present invention comprises housing 1, baffle plate end cap 2, main shaft 3, cam 4, push rod 5, transition rod 6, push rod stop collar 7, push rod spring cover 8, spring 9, tightening key 10, main shaft end cap 11, motor fixing plate frame 14, motor 15, motor cavity urceolus 16, oil sac 17, end cap 18, watertight line interface 20, O shape circle 21; Wherein, described motor 15 is fixed on the motor fixing plate frame 14, and motor fixing plate frame 14 is fixed on the housing 1; Motor 15 and motor fixing plate frame 14 are positioned at the motor cavity of being made up of housing 1, motor cavity urceolus 16, oil sac 17 and end cap 18 and watertight wire terminal 20; Main shaft end cap 11, bolt 12 and tightening key 10 are consolidated output shaft, main shaft 3, the cam 4 of motor 15; Transition rod 6 places in the through hole of housing 1, can slide vertically, and an end contacts with cam 4, the other end contacts with push rod 5, and inlays steel ball at an end that contacts with cam 4; Push rod spring cover 8 is consolidated by nut 13 with push rod 5, and push rod 5 has two protrusion steps, cooperates with transition rod 6, and restriction transition rod 6 moves; Push rod 5 can slide in the through hole of housing 1, and baffle plate end cap 2 and push rod stop collar 7 all are fixed on the housing 1; Contact surface seals with O shape circle 21 between main shaft 3 and the housing 1; Oil sac 17 has the effect of isolating motor cavity interior oil and outside seawater; Use seal with O ring between end cap and the watertight wire terminal; Because enclosing, O shape can't bear big pressure reduction under 21 dynamic seals, so be full of fluid in the motor cavity, motor urceolus 16 walls have the very little through hole of diameter 19, can allow seawater enter between oil sac 17 and the motor cavity urceolus 16, make motor cavity inner identical with external pressure, thereby reduced the pressure-bearing burden of mechanical part, and influenced the electric system of motor cavity hardly.Motor cavity is connected by watertight wire terminal 20 with extraneous.
Be released object and hang over push rod 5 and baffle plate end cap 2 position contacting, when push rod 5 slides off baffle plate end cap 2, mean that a release movement takes place.The power of push rod 5 is from spring 9.
As shown in Figure 2, all in all, six push rods of an electric machine control carry out releasing operation successively.Six unit are circumferential arrangement.
As shown in Figure 2, the through hole of housing 1 has guide function, and cam 4 has the effect of control transition rod 6 displacements.
Housing 1, baffle plate end cap 2, main shaft 3, cam 4, push rod 5, transition rod 6, push rod stop collar 7, tightening key 10, main shaft end cap 11, motor cavity urceolus 16, end cap 18 adopt titanium alloy material to make.Spring 9, motor fixing plate frame 14 are made by stainless steel material.All relate to O shape circle and are made by FFKM.
Working process of the present invention is as follows:
1, as shown in Figures 1 and 2, when cam 4 is not in trigger position, push rod 6 tops contact baffle plate end cap 2, although spring 9 thrust are arranged, because the screens effect of transition rod 6, push rod can not move axially.Be in not release position this moment.
2, as depicted in figs. 1 and 2, when the groove of cam 4 rotation during to the position of a certain transition rod, the transition rod has axially had mobile space, push rod 5 no longer is subjected to the position constraint of transition rod 6, thereby it is mobile in the hole under the effect of spring 9 power, and then the contacting of disengaging and baffle plate end cap 2, hang over treating that releaser is known from experience under the effect of buoyancy or gravity and successfully discharging of push rod end.
3, after finishing one release, cam 4 can continue rotation, carries out the release of other releasing units, push rod 5 with will not influence the release of other unit after push rod stop collar 7 contacts.
