Description
Technical field
The present invention relates to the hatch door forced locking devices on the pneumatic shell of deep-sea, belong to diving equipment field.
Background technology
Manned deep-sea vehicle is one of the Key Platform of deep-sea scientific research, hatch door as manned deep-sea vehicle critical component it
One, it is related to the safety of scientific research personnel and bathyscaph itself inside bathyscaph, cabin door locking apparatus should have high reliability, and
It is easy to operate, it is ensured that the good seal of manned capsule ensures internal staff and electrical equipment safety.
Existing cabin door device is divided into two classes：One kind is hatch door and housing hinge, and hatch door is locked by briquetting compression shell,
It is simple in structure, but long-term action will lead to the abrasion and deformation of shell and hatch door, lead to seal failure；It is another kind of be hatch door and
Shell is locked by pin, reliable lock, but its sealing effect is difficult to meet the requirement of bathyscaph.No matter which kind of, be all logical
It crosses handwheel dependence and is accomplished manually manual locking.
Application No. is the patent document of 201410083776.4 entitled " deep sea manned submersible hatch board locking devices ", institutes
The hold-down mechanism connecting rod quantity of design is more, easy to wear, can reduce the reliability of self-locking in shaft after transmission thread abrasion.Application number
For a kind of patent document of 201510737765.8 entitled " cabin door locking apparatus on the pneumatic shell of deep-sea ", designed cunning
Flange of rail block hole forms guide rail with end cap cylindrical fit, and gap is small to be susceptible to stuck situation, and then guide effect is poor greatly in gap.By
It being compressed in using lever principle, pressing force shows that the axial distance on shaft thread is small, if shaft loosens,
Can then pressing force be caused to die-off, seal failure.Two above patent is all by manually completing compression action by handwheel, and labour is strong
Degree is big and pressing force control is inaccurate.

Specific implementation mode
A kind of hatch door forced locking device on the pneumatic shell of deep-sea of the present invention, including hatch door 3 and pass through screw 21
The end cap 20 being connect with hatch door 3, shaft 4 are mounted between end cap 20 and hatch door 3, and 4 upper end of shaft passes through sealing ring 24 and sealing
Washer 25 completes dual-seal, and 4 lower end of shaft is completed axial limiting by Step Shaft and 20 respective step hole of end cap and coordinated.Hatch door
3 and shell 1 connected by lug 6,10 and first connecting rod 8, second connecting rod 9, to neutral good.The people driven by electrical control lines 28
Work muscle 26 is placed in the arc chute of end cap 20, and sliding slot both ends are limited with door 27；Class ratchet spanner is cased in shaft 4
One end of pedestal 15, class ratchet spanner pedestal 15 is inserted into artificial-muscle 26, and class ratchet spanner pedestal 15 and artificial-muscle 26 exist
Interference fit in card slot, class ratchet spanner bottom are equipped with groove, and spring 16 and holder 17 are provided in groove, and holder 17 is to push up
Bar, holder are compressed with the ratchet in end cap, and the gear teeth meshing being arranged on ratchet and shaft is stretched by the compression of artificial-muscle
Exhibition, class ratchet spanner pedestal do the swing of certain angle in arc chute, and shaft is driven to rotate counterclockwise, wherein ratchet, top
Son and spring complete unidirectional self-lock (see Fig. 6) together, i.e., cannot complete to rotate clockwise, pass through the feed screw nut pair in shaft 4
It drives draw nut 5 to move up and down in an axial direction, the parallel four-bar machine being made of check lock lever 11 and connecting rod 12 is driven by push rod 14
Structure acts, and compression action is completed by 11 tapered end of check lock lever.
In the present invention, the ratchet mechanism completes the axial limiting in shaft by upper cover 18 and end cap 20, passes through
The action of reversing handle 19-2, thus it is possible to vary ratchet mechanism then completes the shape of locking and unlock for the driving direction of shaft 4
State switches.
In the present invention, class ratchet spanner pedestal 15, spring 16, holder 17, upper cover 18, ratchet are coordinated with artificial-muscle 26
The ratchet mechanism that 19-1 is constituted replaces artificial handwheel to complete locking and unlocking motion, and coupling mechanism force is accurate, and double self locking is more reliable.
In the present invention, it is that special guide groove 3-2 is arranged in draw nut 5, the self-locking situation for avoiding frictional force from bringing will lock
Tight 11 end wedge shape pressing force of bar is converted into 12 tension of connecting rod and push rod 14 is pressurized, and two power rod-type stress forms are conducive to structure hair
Wave material property.
Locking process：When 3 non-locking state of hatch door, 11 tapered end of check lock lever is far from shell 1, and draw nut 5 is close to hatch door.
Aquanaut adjusts commutation spanner 19-2 to right position (see Fig. 6), connects electrical control lines 28 and gives the power supply of artificial-muscle 26 (electric control part in figure
Do not illustrate), the handle of class ratchet spanner pedestal 15 does one under the compressing and stretching cooperation of end cap arc chute both sides artificial-muscle
Determine the reciprocally swinging of angle, coordinates rotating counterclockwise (see Fig. 6) for spring 16, holder 17 and ratchet 19-1 completion countershafts 4, lead to
The feed screw nut pair crossed in shaft 4 drives the lower movement in an axial direction of draw nut 5, is driven by check lock lever 11 and connecting rod by push rod 14
The parallelogram lindage action of 12 compositions, drives 11 translation motion of check lock lever, its tapered end is made to complete compression action.Draw spiral shell
Mother 5 is to be threadedly coupled with shaft 4, is in self-locking state after locking；By ratchet self-locking at shaft gear, it is dynamic to complete locking in check lock lever
After work, double self locking ensures that locking state is reliable.
Releasing process is opposite with above-mentioned locking process operation：Aquanaut adjusts commutation spanner 19-2, and to left position, (direction refers to
Fig. 6), it connects electrical control lines 28 to power (electric control part is not illustrated in figure) to artificial-muscle 26, the handle of class ratchet spanner pedestal 15
The reciprocally swinging of certain angle, cooperation spring 16, top are done under the compressing and stretching cooperation of end cap arc chute both sides artificial-muscle
What son 17 and ratchet 19-1 completed countershaft 4 rotates clockwise (direction is with reference to figure 6), passes through feed screw nut's subband in shaft 4
Dynamic draw nut 5 moves (direction is with reference to figure 6) vertically, is driven by push rod 14 and is put down by what check lock lever 11 and connecting rod 12 formed
Row four-bar mechanism acts, and drives 11 translation motion of check lock lever, its tapered end is made to complete unlocking motion, realizes that hatch door is opened.It leads
It is to be threadedly coupled to draw nut 5 with shaft 4, is in self-locking state after unlock；By ratchet self-locking at shaft gear, complete to solve in check lock lever
After lock action, double self locking ensures that unlocked state is reliable.
The opening and closing process of hatch door 3-1：Hatch door 3-1 is connect with shell 1 by three bar configuration.Aquanaut (or out of my cabin
Staff) hatch door 3-1 pulled up by hatch door handle 2, it realizes the separation of hatch door 3-1 and shell 1, is then moved to shell
Hatch door 3-1 opening actions are realized in 1 side of body.Aquanaut (or extravehicular operation personnel) pulls hatch door 3-1 by hatch door handle 2, makes
Hatch door 3-1 is erect, and then completing the centering with shell by two hatch door handles operates, and finally pushes, realizes that hatch door 3-1 is closed
Action.
Still there are inside and outside handwheel installation sites in shaft by the present invention, to prevent in emergency manual unlocking
Or external rescue.It should be understood that：1. the action for the spanner 19-2 that commutates also can be from similar to appropriate configuration with above-mentioned artificial-muscle 26
It realizes, realizes the full automation locking operation of hatch door.
