Specifically, in one embodiment, a flow of an automatic cover opening and closing method suitable for a waterproof pressure-resistant cabin is as follows: the rotating motor 9 drives the top cover 5 to a horizontal position, and the rotating motor stops working at the moment; then the third telescopic motor 16 and the fourth telescopic motor 17 are electrified to work, and the telescopic motors start to contract; according to a preset program, the four telescopic motors are approximately contacted with the top cover at the same time point, the nuts on the upper parts of the telescopic motors apply pressure to the top cover, the telescopic motors are blocked, the working current is increased, the positive and negative current limiting control module is powered off, and the current direction is reversed; the top cover 5 applies pressure to the O-shaped rubber ring 4, the O-shaped rubber ring deforms under stress to be in close contact with the top cover 5 and the sealing flange 3, the sealing effect is achieved, and the cover closing action is completed. First, second, third, fourth telescopic motor circular telegram, the motor extension rises, waits third, fourth telescopic motor all to rise to the top after, and the circular telegram of rotating electrical machines 12 drives top cap 5 rotatory to vertical position, and the action of uncapping is accomplished.

The invention provides an automatic cover opening and closing device for realizing the function of launching internal components in the sky for an underwater vehicle, the underwater vehicle is waterproof and sealed when submerging, and a hatch cover can be completely opened when on the water surface, so that the three-dimensional continuous observation and reconnaissance in the sea and the sky can be realized. The cover opening and closing device adopts two groups of motors to meet the cover opening requirement and the water tightness requirement, does not need complicated electromechanical control and mechanical structures, and has low cost. The motors used by the cover opening and closing device are provided with overcurrent protection and automatic positive and negative current regulation modules, so that the water tightness requirement of the cabin body after the cabin cover is tightly pressed can be guaranteed, and the motors cannot be burnt out due to long-time rotation blockage.

The invention discloses an automatic cover opening and closing device of a waterproof pressure-resistant cabin, which realizes waterproof sealing when the pressure-resistant cabin submerges and can completely open a cabin cover when the pressure-resistant cabin is on the water surface. The cover opening and closing actuator drives a bracket connected with the top cover through a motor to realize the rotary opening and closing of the top cover at an angle of 90 degrees in a vertical plane; the cover opening and closing assembly compresses the top cover by using the motor connected with the cylinder support, so that the sealing between the top cover and the cylinder is realized. The invention adopts a mode of driving the opening and closing cover by two groups of motors, ensures that the waterproof pressure-resistant cabin meets the underwater sealing condition, can emit and carry a small-sized detection device to the air on the water surface, and can realize the three-dimensional continuous observation and reconnaissance in the sea and the air.
