DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0027] like Figures 1 to 5 As shown, a stairway hatch cover for a floating production storage vessel comprises a mounting frame 1, a rotating cover plate 2 rotatably arranged on the outer wall of the mounting frame 1, a door opening mechanism 31 is arranged inside the mounting frame 1, a sealing mechanism 32 is arranged on the outer wall of the mounting frame 1, the door opening mechanism 31 comprises a motor 311, a first groove is arranged on the inner wall of the mounting frame 1, the bottom end of the motor 311 is fixedly connected to the bottom end of the inner wall of the first groove, a threaded rod 312 is fixedly connected to the output end of the motor 311, a threaded block 313 is threadedly connected to the outer wall of the threaded rod 312, a movable cover plate 316 is fixedly connected to the outer wall of the threaded block 313, and the outer wall of the movable cover plate 316 fits the inner wall of the mounting frame 1, thereby ensuring that the movable cover plate 316 is in close contact with the inner wall of the mounting frame 1. 16 In the closed state, the installation frame 1 is well fitted and sealed. The movable cover 316 is fixedly connected to the slider 315 at one end away from the threaded block 313. A sliding groove is provided on the inner wall of the installation frame 1 away from the first groove. The inner wall of the sliding groove is fixedly connected to the sliding rod 314. The inner wall of the sliding rod 315 is slidably connected to the outer wall of the sliding rod 314. A second groove is provided on the outer wall of the movable cover 316. The inner wall of the second groove is fixedly connected to the first capstan 317. The first capstan 317 is rotatably connected to a connecting rotating rod 318. The connecting rotating rod 318 is rotatably connected to a second capstan 319 at one end away from the first capstan 317. One end of the second capstan 319 is fixedly connected to the inner outer wall of the rotating cover 2.

[0028] Furthermore, there are two connecting rods 318, which are symmetrically distributed on the left and right inner walls of the movable cover 316. The initial state of the connecting rods 318 is an inclined state, which can evenly support the left and right sides of the rotating cover 2 and the movable cover 316, thereby improving the support stability of the rotating cover 2. At the same time, the connecting rods 318 in the initial state can exert an outward thrust on the rotating cover 2 during its upward movement, thereby facilitating the opening of the rotating cover 2.

[0029] Furthermore, the first groove and the inner wall of the slide groove formed on the inner wall of the mounting frame 1 are respectively fitted with the outer walls of the threaded block 313 and the slider 315 , thereby improving the stability of the threaded block 313 and the slider 315 during the up and down movement and maintaining their smooth movement.

[0030] The sealing mechanism 32 includes a sealing strip 322 fixedly connected to the outer wall of the rotating cover plate 2. A sealing groove 321 is provided on the outer wall of the mounting frame 1. The sealing strip 322 is sealingly connected to the inner wall of the sealing groove 321.

[0031] Furthermore, the sealing strip 322 is made of soft rubber, and the outer wall of the sealing strip 322 is larger than the inner wall of the sealing groove 321 , so that the inner wall of the sealing groove 322 is filled with the rebound effect after the sealing strip 322 is squeezed into the sealing groove 321 , thereby improving its sealing effect.

[0032] The implementation principle of a floating production storage and offloading vessel stairway hatch cover of this embodiment is as follows: when it needs to be opened, first start the motor 311, and its output end will drive the threaded rod 312 to rotate. When the threaded rod 312 rotates, it can drive the threaded block 313 to move upward, so that the threaded block 313 will drive the movable cover plate 316 to move upward. When the movable cover plate 316 moves, it drives the slider 315 to move upward on the outer wall of the slide rod 314, thereby supporting the movable cover plate 316, making the movement process smoother. When the movable cover plate 316 moves upward, it will drive the first capstan 317 and the connecting rotating rod 318 to move upward. At this time, the connecting rotating rod 318 will rotate with the first capstan 317 and the second capstan 319, pushing the rotating cover plate 2 to rotate, so that the rotating cover plate 2 appears in an open and closed state, and at the same time, the movable cover plate 316 will move to the top 1 of the installation frame 1, and the hatch door can be opened at this time. The rotation of the rotating cover plate 2 after opening takes up less space, which is more convenient for the staff to carry goods.

[0033] When the rotating cover 2 is in a closed state, the sealing strip 322 on its outer wall will be engaged in the sealing groove 321 to complete the sealing effect on the top of the mounting frame 1. The rotating cover 2 in the closed state is at the upper end of the movable cover 316, so that the sealing effect of the entire hatch can be maintained in the closed state.
