Specific implementation manner

[0027] Embodiment:

[0028] The following further elaborates on the present utility model in conjunction with the attached Figure 1-6 drawings.

[0029] The opening and closing device of the deep-sea high-pressure simulation cabin includes a loading and unloading cover module 20 and a closing module 30, which need to be used in cooperation with the simulation cabin body 10 and are arranged in the corresponding sunken foundation pit. As Figure 1 , Figure 2 and Figure 6 shown, both the loading and unloading cover module 20 and the closing module 30 are arranged on the ground of the sunken foundation pit, and the sunken foundation pit is provided with stairs leading to the ground.

[0030] The simulation cabin body 10 is defined according to the requirements of the simulation test as needed, and there is no specific design requirement. The loading and unloading cover module 20 and the closing module 30 are adjusted according to the size of the simulation cabin body 10, and the design concept of the whole set of system is applicable to simulation cabin bodies 10 of different models and sizes.

[0031] As Figure 3 shown, the simulation cabin body 10 is composed of a cabin body 12, a hatch 13, a bottom cabin and a cabin cover 11. The cabin body 12 of the simulation cabin body 10 is buried underground in the sunken foundation pit, the hatch 13 is arranged at the top of the cabin body 12 and is of an outward-expanded structure, and the hatch 13 extends out of the ground of the sunken foundation pit. The bottom cabin is installed at the bottom of the cabin body 12 and is used for protecting and supporting the cabin body 12, etc. A detachable docking cabin cover 11 is arranged on the hatch 13. A docking ring and a matching seal are provided at the lower end of the cabin cover 11. After the hatch 13 and the cabin cover 11 are docked, the simulation cabin body 10 can be basically sealed.

[0032] The hatch cover 11 of the simulation cabin body 10 matches the hatch 13 on the cabin body 12. The loading and unloading cover module 20 is docked on the hatch cover 11. The loading and unloading cover module 20 drives the hatch cover 11 to approach or move away from the hatch 13, and can also control the close connection or separation of the hatch cover 11 and the hatch 13. These two actions should be continuously implemented. A closing module 30 is provided beside the hatch 13. The closing module 30 strengthens or relaxes the alignment of the hatch cover 11 and the hatch 13. The change in the relative position of the hatch cover 11 and the hatch 13 drives the closing or opening of the simulation cabin body 10.

[0033] The loading and unloading cover module 20 rotates and transports the docked hatch cover 11 above the hatch 13 and aligns it, triggers the clamp, the hatch cover 11 and the hatch 13 are connected and installed, after the closing module 30 tightens, it clamps and wraps the aligned hatch cover 11 and hatch 13, and the simulation cabin body 10 is closed. After the closing module 30 is released, the aligned hatch cover 11 and hatch 13 are loosened, the hatch cover 11 and the hatch 13 are separated, the loading and unloading cover module 20 releases the clamp and rotates and transports the aligned hatch cover 11 away from above the hatch 13, and the simulation cabin body 10 is opened.

[0034] Such as Figure 4As shown in the figure, the loading and unloading cover module 20 includes a rotating column 21, a loading and unloading cover beam 22, a torsion frame 24, a rotating unit 23, a hydraulic system, a support frame 25, an arc-shaped track 26, and large traveling wheels 27. The rotating column 21 is fixedly erected on the ground of the sunken foundation pit. The top of the rotating column 21 is provided with a rotating unit 23, and the rotating unit 23 is also connected to a loading and unloading cover beam 22. The loading and unloading cover beam 22 rotates around the rotating column 21 through the rotating unit 23. A torsion frame 24 is provided on the beam body of the loading and unloading cover beam 22 through a hydraulic system, and the hydraulic system drives the hatch cover 11 connected to the torsion frame 24 to move up and down. The hydraulic system is an integrated transmission control system. In addition to controlling the lifting action of the torsion frame 24, there is also a branch that is separately connected to the clamp on the hatch cover 11, and the clamp is controlled to trigger and fasten or release the corresponding position on the hatch 13 through hydraulic transmission to realize the automatic and intelligent control of the docking and separation of the hatch cover 11 and the hatch 13. The setting position of the torsion frame 24 ensures that the torsion frame 24 can accurately appear directly above the hatch 13 during the synchronous rotation with the loading and unloading cover beam 22. In this way, after the torsion frame 24 is connected to the hatch cover 11, the alignment of the hatch cover 11 and the hatch 13 and the docking action after alignment can be completed. A vertical support frame 25 is provided at the non-rotating end of the loading and unloading cover beam 22. The support frame 25 is used to maintain the horizontal state of the loading and unloading cover beam 22 to prevent the beam body from tilting due to overweight caused by the excessive length of the loading and unloading cover beam 22, so as to ensure the use accuracy. An arc-shaped track 26 is laid on the ground of the sunken foundation pit. The position where the arc-shaped track 26 is set coincides with the rotation track of the loading and unloading cover beam 22, and the length of the arc-shaped track 26 is the same as the rotation stroke of the loading and unloading cover beam 22. Large traveling wheels 27 are provided at the bottom of the support frame 25, and the large traveling wheels 27 are cooperatively arranged on the arc-shaped track 26 to form a movement structure similar to that of a train and a railway track. The large traveling wheels 27 and the arc-shaped track 26 cooperate with the rotation action of the loading and unloading cover beam 22. The large traveling wheels 27 and the arc-shaped track 26 assist the support frame 25 in maintaining stability.

[0035] As Figure 5As shown in the figure, the closing module 30 includes two semi-circular pressing dies 31, two sets of hydraulic transmission groups 32, two support legs 33, two lifting frames 35, two sets of small traveling wheels 37, and two sets of straight running rails 36. The semi-circular pressing die 31 is provided with a concentric semi-circular through groove, and the through direction is the vertical direction. An embedded limiting groove is opened towards the inner arc surface in the horizontal direction. The dimensions such as the radian, depth, and thickness of the limiting groove should fit the docking structure of the hatch cover 11 and the hatch 13. The two semi-circular pressing dies 31 can be butted laterally to form a complete circular ring structure, and the aligned and inserted hatch cover 11 and hatch 13 structures are clamped and covered through the two limiting grooves. The hydraulic transmission group 32 is inserted horizontally and centripetally along the arc top of the semi-circular pressing die 31. One end of the hydraulic transmission group 32 abuts against the hatch cover 11 or the hatch 13, preferably the hatch 13, and the other end passes through and is fixed on the corresponding side of the semi-circular pressing die 31. In this way, the relative telescoping of the two ends of the hydraulic transmission group 32 can cause the two semi-circular pressing dies 31 to approach or move away from each other. A support leg 33 is installed at the bottom of the arc vertex of the corresponding side of the semi-circular pressing die 31. The height of the support leg 33 is such that the semi-circular pressing die 31 is horizontally arranged, and a traveling wheel 34 in contact with the ground is provided at the bottom of the support leg 33. Two symmetrically arranged lifting frames 35 are provided beside the hatch 13. The straight running rails 36 are provided on the lifting frames 35. The straight running rails 36 are arranged parallel to the movement direction of the semi-circular pressing die 31, that is, the telescoping direction of the hydraulic transmission group 32. A small traveling wheel 37 is provided at each of the two end bottoms of the cross-section of the bottom of the semi-circular pressing die 31, and the small traveling wheel 37 is cooperatively arranged on the straight running rail 36. The lifting frames 35, the small traveling wheels 37, the support feet, and the traveling wheels 34 all play a supporting role for the semi-circular pressing die 31 to keep it horizontal. The small traveling wheels 37 and the straight running rails 36, the support frames 25 and the traveling wheels 34 all cooperate with the linear movement of the semi-circular pressing die 31 to play an auxiliary supporting role.

[0036] The working process of the opening and closing device is as follows: the torsion frame 24 descends and docks the hatch cover 11 through the preset bolts on the torsion frame 24 and the preset interface on the hatch cover 11, connects the hydraulic system and the clamp on the hatch cover 11, and drives the loading and unloading cover beam 22 through the rotating unit 23 to align the hatch cover 11 and the hatch opening 13; the large running wheels 27 at the bottom of the support frame 25 roll along the arc-shaped track 26, synchronously cooperating with the rotation of the loading and unloading cover beam 22; the torsion frame 24 continues to descend, so that the hatch cover 11 is embedded in the hatch opening 13; the hydraulic system triggers the clamp The clamp is fastened and locked in the corresponding position of the hatch 13, completing the sealed docking of the hatch cover 11 and the hatch 13; the loading and unloading cover module remains silent, and the motor is locked; the two semicircular pressing molds 31 approach each other under the action of the hydraulic transmission group 32 until they are completely docked, forming a complete disc structure; the running wheel 34 at the bottom of the support frame 33 rolls on the ground of the sunken foundation pit, and the small running wheel 37 at the bottom of the semicircular pressing mold 31 rolls along the straight running rail 36, synchronously cooperating with the displacement action of the semicircular pressing mold 31; the hatch cover 11 and The hatch 13 is embedded in and covered in the limiting groove of the semicircular die 31; the closing module remains silent and the motor is locked; the simulation cabin body 10 is closed and the simulation experiment begins; the two semicircular dies 31 move away from each other under the action of the hydraulic transmission group 32 until the hatch cover 11 and the hatch 13 are separated from the limiting groove of the semicircular die 31; the running wheels 34 at the bottom of the support frame 33 roll on the ground of the sunken foundation pit, and the small running wheels 37 at the bottom of the semicircular die 31 roll along the straight track 36, synchronously cooperating with the semicircular die 31 Displacement action; the hydraulic system releases the clamp, the clamp loosens and moves away from the hatch 13, completing the separation of the hatch cover 11 and the hatch 13; the torsion frame 24 is lifted to make the hatch cover 11 leave the hatch 13, and the loading and unloading cover beam 22 is driven to rotate in the opposite direction through the rotating unit 23; the large running wheels 27 at the bottom of the support frame 25 roll along the arc-shaped track 26, synchronously cooperating with the rotation action of the loading and unloading cover beam 22; the hatch cover 11 is able to stagger away from the hatch 13; the simulated cabin body 10 is completed to be opened for cleaning or maintenance, or other corresponding operations.
