[0024] An annular raceway A102 is provided on the circumferential outer wall at the top end of the cabin body 1, and an annular raceway B34 is provided at the lower end of the inner circumference of the lock ring 3 at the position corresponding to the annular raceway A102. A plurality of rolling elements 6 are provided between the annular raceway A102 and the annular raceway B34. The rolling elements 6 are spherical or cylindrical structures, and the lock ring 3 is rotatably connected to the cabin body 1 through the rolling elements 6; the top end of the lock ring 3 is located above the top end of the cabin body 1, and wedge blocks 231 are equally spaced at the upper end of the inner circumference of the lock ring 3, and a relief notch 32 is formed between the wedge blocks 231;

[0025] Two lock ring driving mechanisms 4 that can drive the lock ring 3 to rotate circumferentially are provided on the outer wall of the cabin body 1, and the two lock ring driving mechanisms 4 are symmetrically arranged along the center line of the cabin body 1; the lock ring driving mechanism 4 includes a fixed support 41 fixedly provided on the cabin body 1, and a horizontally arranged telescopic cylinder 42 is movably connected to the fixed support 41 through a pin shaft, and a connecting ear plate 33 is provided on the lock ring 3 at the telescopic end corresponding to the telescopic cylinder 42, and the telescopic end of the telescopic cylinder 42 is movably connected to the connecting ear plate 33 through a pin shaft.

[0026] The outer circumferential wall at the bottom end of the hatch cover 2 is provided with wedge blocks 22 that match the structure of wedge block 2 31 at equal intervals, and after the lock ring 3 rotates circumferentially, the wedge surface at the bottom end of wedge block 2 31 can fit tightly with the wedge surface at the top end of wedge block 1 22;

[0027] A hatch cover driving mechanism 5 which can drive the hatch cover 2 to flip in the vertical direction is also provided on the outer wall of the cabin body 1, and the hatch cover driving mechanism 5 includes a flip bracket 51 fixedly provided on the hatch cover 2, and a fixed support 2 53 and a hinge support 54 are fixedly provided on the outer wall of the cabin body 1; the hinge support 54 is rotatably connected to the flip bracket 51 through a pin shaft, and a vertically arranged telescopic cylinder 2 52 is movably connected between the fixed support 2 53 and the outer end of the flip bracket 51 through a pin shaft.

[0028] Working principle:

[0029] Opening the test cabin: the lock ring 3 is pushed to rotate counterclockwise by extending the telescopic cylinder 1 42 so that the notch 32 on the lock ring 3 coincides with the wedge 22 on the cabin cover 2. The flip bracket 51 and the cabin cover 2 are flipped upward around the pin connected to the hinge support 54 by contracting the telescopic cylinder 2 52. The cabin cover 2 is opened and the test object is placed in the cabin body 1.

[0030] Closing the test hatch: the flip bracket 51 and the hatch cover 2 are pushed downward by extending the telescopic cylinder 2 52, and the hatch cover 2 is slowly closed. The locking ring 3 is pushed clockwise by extending the telescopic cylinder 1 42, so that the wedge block 2 31 on the locking ring 3 coincides with the wedge block 1 22 on the hatch cover 2, and the wedge surface at the bottom end of the wedge block 2 31 fits tightly with the wedge surface at the top end of the wedge block 1 22, thereby locking the hatch cover 2 and the cabin body 1 to form a closed cavity between the hatch cover 2 and the cabin body 1. By injecting pressurized seawater from the water inlet 21 of the hatch cover 2, deep-sea pressure conditions can be simulated, and conditions of different diving depths can be simulated by adjusting the seawater pressure.

[0031] Furthermore, positioning ball sockets 23 are equidistantly arranged along the circumferential direction of the bottom surface of the hatch cover 2, and ball head pins 7 are fixedly arranged at positions on the top surface of the cabin body 1 corresponding to the positioning ball sockets 23. When closing the hatch of the test cabin, when the end face of the hatch cover 2 approaches the end face of the cabin body 1, automatic positioning and deviation correction are achieved through the ball head pins 7 on the cabin body 1 and the positioning ball sockets 23 on the hatch cover 2, ensuring that the cabin body 1 and the hatch cover 2 are concentric until they are tightly attached.

[0032] Furthermore, a sealing gasket 24 is provided on the bottom surface of the hatch cover 2 to improve the sealing performance of the test cabin.

[0033] The deep-sea simulation test cabin disclosed in this embodiment drives the lock ring 3 to rotate through the lock ring drive mechanism 4, thereby realizing automatic locking or loosening between the hatch cover 2 and the cabin body 1, and drives the hatch cover 2 to flip through the hatch cover drive mechanism 5, thereby realizing automatic opening or closing of the hatch cover 2. The efficiency of opening and closing the hatch cover 2 is high, the speed of opening or closing the hatch is fast, the degree of automation is high, the sealing performance between the hatch cover 2 and the cabin body 1 is good, and the locking between the hatch cover 2 and the cabin body 1 is reliable, which can meet the strength requirements of deep-sea high-pressure simulation experiments.
