[0023] In this embodiment, the bottom of the support body 1 can be supported by the mounting base 3 and the connecting plate 4, so as to realize the stable connection of the support body 1, thereby assisting the installation and fixation of the entire device. The cross section of the reinforcing member 14 is T-shaped, the top of which overlaps with the end of the support body 1, and the bottom is connected to the inner wall of the support body 1, so that the reinforcing member 14 can be stably connected to the support body 1. The two ends of the hydraulic push rod 514 can be connected to the hatch cover body 51 and the guide plate 512 respectively through the connecting member 2 513 and the connecting member 1 511, so that the hydraulic push rod 514 can be installed and used on one side of the hatch cover body 51.

Since one side of the guide block 12 is fixedly connected to the limit block 121, the limit block 121 is used to The engagement with the connecting piece three 52 can limit the connecting piece three 52, so that the position of the hatch cover body 51 is locked after the hatch cover body 51 is closed, avoiding the safety hazard caused by the hatch cover body 51 being opened by accident. The limit block 121 and the guide block 12 are detachable, so when the hatch cover body 51 is opened, the limit block 121 is separated from the guide block 12, which can reduce the interference of the limit block 121 and the guide block 12 on the movement of the hatch cover body 51, thereby ensuring the normal rotation and opening of the hatch cover body 51.

[0024] Embodiment 2: According to Figure 1-Figure 7As shown, the driving assembly 2 includes a bevel gear 21, a belt body 22 and a flat gear 23. The bottoms of the bevel gear 21 and the flat gear 23 are both rotatably connected to the support body 1, and the tops of the bevel gear 21 and the flat gear 23 are fixedly connected with pulleys 24. The outer annular surfaces of the pulleys 24 are transmission-connected to the belt body 22, and one side of the bevel gear 21 is meshed with the bevel gear 2 53, and one side of the flat gear 23 is meshed with the gear ring 13. A reinforcing rib 1 515 is fixedly connected to one side of the hatch cover body 51, and a reinforcing rib 2 516 is inserted through the interior of the reinforcing rib 1 515.

[0025] In this example, the support body 1 can be used to support the bottom of the bevel gear 21 and the flat gear 23, so that the rotation of the bevel gear 21 and the flat gear 23 can be realized. The bevel gear 21 and the flat gear 23 are connected by the belt body 22, so that the synchronous rotation of the bevel gear 21 and the flat gear 23 can be realized. The outer ring surface of the pulley 24 is provided with an annular groove to avoid the separation of the belt body 22 and the pulley 24, thereby ensuring the transmission effect of the belt body 22 on the pulley 24, and then the gear ring 13 can be driven to rotate by the rotation of the pulley 24. The reinforcing rib 1 515 can support and reinforce the side wall of the hatch cover body 51, and the reinforcing rib 2 516 and the reinforcing rib 517 can be used to support and reinforce the side wall of the hatch cover body 51. The rib 1515 is connected to increase the contact area with the side wall of the hatch cover body 51, and the connection of the reinforcing rib 515 is supported, so as to further improve the reinforcement effect on one side of the hatch cover body 51 and improve the overall strength of the hatch cover body 51, thereby reducing the deformation of the hatch cover body 51 after being damaged. The reinforcing member 14 can be used to support the bottom of the hatch cover body 51 to limit the placement state of the hatch cover body 51 when it is closed. The sealing ring 142 can increase the contact area between the reinforcing member 14 and the bottom of the hatch cover body 51. The sealing ring 142 can be used to perform preliminary sealing protection on the connection between the hatch cover body 51 and the reinforcing member 14, thereby reducing the flow of water into the support body 1.

[0026] Embodiment 3: According to Figure 1-Figure 8As shown, an auxiliary mechanism 6 is provided on one side of the gear ring 13, and the auxiliary mechanism 6 includes a vertical drive shaft 61, a worm gear 64 and a connecting plate 65. The vertical drive shaft 61 is inserted through the support body 1, and a flat gear 62 is inserted through the outside of the vertical drive shaft 61, and one side of the flat gear 62 is meshed with the gear ring 13. A worm 63 is fixedly connected to the bottom of the vertical drive shaft 61, and the bottom of the worm 63 is rotatably connected to the mounting base 3. One side of the worm 63 is meshed with the worm wheel 64, and one side of the worm wheel 64 is rotatably connected to the connecting plate 4. A reinforcing rod 68 is inserted through the inside of the worm wheel 64, and one end of the reinforcing rod 68 is fixedly connected to the connecting plate 65, and the connecting plate 65 is connected to the connecting plate 4. The connecting plate 65 is rotatably connected thereto, a connecting rod 1 66 is hinged on one side of the connecting rod 1 66, a connecting rod 2 67 is hinged on one side of the connecting rod 1 66, a sealing gasket 1 7 is hinged on the top of the connecting rod 2 67, the outer ring surface of the sealing gasket 1 7 is slidingly connected to the inner wall of the support body 1, an anti-slip rod 73 is fixedly connected to the top of the sealing gasket 1 7, a sealing gasket 2 71 is slidingly connected to the top of the anti-slip rod 73, the outer ring surface of the sealing gasket 2 71 overlaps the inner wall of the support body 1, the inner ring surface of the sealing gasket 2 71 is fixedly connected to a sealing ring 2 72, the top of the sealing gasket 2 71 is fixedly connected to a connecting ring 711, the top of the connecting ring 711 is engaged with the annular groove, and the annular groove is provided at the bottom of the reinforcement 14.

[0027] In this embodiment, the coaxial connection between the flat gear 2 62 and the worm 63 can be realized through the vertical drive shaft 61, and the bottom of the worm 63 is rotatably connected to the mounting base 3. The mounting base 3 can be used to support the bottom of the worm 63, thereby improving the stability of the worm 63 and the vertical drive shaft 61 during rotation. The flat gear 2 62 is overlapped above the support body 1, and the diameter of the flat gear 2 62 is larger than the vertical drive shaft 61, so the vertical drive shaft 61 will not fall off the support body 1, which can ensure that the vertical drive shaft 61 is always meshed with the gear ring 13. When the worm gear 64 rotates, the two flat gears 62 can be driven to rotate at the same time, thereby driving the vertical driving shaft 61 and the worm 63 to rotate. The worm 63 can drive the worm wheel 64 to rotate. The connecting plate 4 can support the rotation of one side of the worm wheel 64, thereby ensuring that the worm wheel 64 and the connecting plate 65 remain stable in the horizontal direction when rotating, thereby maintaining the meshing effect of the worm wheel 64 and the worm 63. The worm wheel 64 and the connecting plate 65 can be connected by the reinforcing rod 68, thereby realizing the synchronous rotation of the worm wheel 64 and the connecting plate 65. The rotation of 65 can drive the connecting rod 1 66 to make a circular motion with the center of the connecting plate 65, and then apply a force to the connecting rod 2 67, and drive the sealing gasket 1 7 to be adjusted along the lifting inside the support body 1 through the hinge connection between the connecting rod 2 67 and the sealing gasket 1 7. Since the connecting rod 2 67 is symmetrically arranged, the sealing gasket 1 7 can be smoothly lifted and lowered by the two connecting rods 2 67. The anti-slip rod 73 can guide the lifting and lowering of the sealing gasket 1 7. At the same time, the diameter of the top of the anti-slip rod 73 is large, so the anti-slip rod 73 and the sealing gasket can be prevented from being lifted and lowered. The sealing gasket 1 71 is separated from the sealing gasket 2 71, thereby ensuring that the sealing gasket 1 7 is always connected to the sealing gasket 2 71 through the anti-detachment rod 73, and the sealing gasket 2 71 can be assisted to connect with the reinforcement 14 through the connecting ring 711. The connecting ring 711 and the sealing ring 2 72 can increase the contact area between the sealing gasket 2 71 and the reinforcement 14, thereby improving the tightness of the connection between the reinforcement 14 and the sealing gasket 2 71, thereby ensuring the sealing effect on the inner wall of the support body 1 and the bottom of the hatch cover body 51, wherein the sealing gasket 1 7, the sealing gasket 2 71 and the sealing ring 2 72 are all made of rubber.

[0028] The method of using the device and the working principle are as follows: first, when the whole device is in use, the mounting hole provided on the mounting base 3 can be used to mount the whole device at the stairway entrance of the ship. After the installation, the contraction of the hydraulic push rod 514 can be used to drive the hatch cover body 51 to rotate around the auxiliary shaft 521. During the contraction of the hydraulic push rod 514, the inclination angle of the hydraulic push rod 514 gradually decreases, and the connecting piece 1 511 at one end of the hydraulic push rod 514 slides along the guide plate 512 until the hydraulic push rod 514 remains horizontal, thereby closing the hatch cover body 51. During the rotation of the hatch cover body 51 and the auxiliary shaft 521, the auxiliary shaft 521 drives the bevel gear 2 53 to rotate, and the bevel gear 2 53 is rotated. The gear 2 53 drives the bevel gear 1 21 to rotate at the top of the support body 1. Under the transmission of the belt body 22, the bevel gear 1 21 and the flat gear 1 23 rotate synchronously, so that the engagement between the flat gear 1 23 and the gear ring 13 can be used to drive the gear ring 13 to rotate, and the gear ring 13 drives the locking ring 11 and the guide block 12 to rotate. The guide rod 122 at the bottom of the guide block 12 moves in the arc-shaped guide groove 141 until the hatch cover body 51 is completely closed, and one side of the limit block 121 is engaged with the connecting piece 3 52. At this time, the bottom of the hatch cover body 51 overlaps with the top of the sealing ring 142, and the limit block 121 locks the position of the hatch cover body 51, and the hatch cover body 51 is in a completely closed state; At the same time, when the gear ring 13 rotates, the gear ring 13 can drive the two flat gears 62 to rotate. The flat gear 62 is coaxially connected to the vertical drive shaft 61, which can realize the rotation of the vertical drive shaft 61, and then drive the worm 63 below to rotate. One side of the worm 63 is meshed with the worm wheel 64, so when the worm 63 rotates, the worm wheel 64 is driven to rotate, and then through the connection of the reinforcement rod 68, the synchronous rotation of the worm wheel 64 and the connecting plate 65 is realized. When the connecting plate 65 rotates, the bottom end of the connecting rod 1 66 rotates with the connecting plate 65, and a force is applied to the connecting rod 2 67. Since the length of the connecting rod 1 66 is fixed, Therefore, when the connecting plate 65 rotates counterclockwise, the second connecting rod 67 can be driven to move upward, thereby driving the sealing gasket 1 7 to slide upward along the inner wall of the supporting body 1. The second sealing gasket 71 can squeeze the reinforcing member 14 after being subjected to the upward force of the sealing gasket 1 7, so that the connecting ring 711 and the reinforcing member 14 are more closely fitted, and the second sealing gasket 71 and the reinforcing member 14 are tightly connected, so that the second sealing ring 72 reinforces the connection between the reinforcing member 14 and the inner wall of the second sealing gasket 71, and the contact area between the second sealing gasket 71 and the bottom of the reinforcing member 14 is increased, thereby improving the sealing effect inside the supporting body 1; A reinforcing rib 1 515 and a reinforcing rib 2 516 are installed on one side of the hatch cover body 51. The reinforcing rib 1 515 and the reinforcing rib 2 516 can be used to support and reinforce one side of the hatch cover body 51 to improve the strength of the hatch cover body 51. When the hatch cover body 51 needs to be opened, the limit block 121 can be removed from one side of the guide block 12, and the hydraulic push rod 514 is extended to drive the hatch cover body 51 to rotate around the axis of the auxiliary shaft 521. At this time, the bevel gear 2 53 rotates in the opposite direction to drive the bevel gear 1 21 to rotate, and then drives the pulley 24 and the gear ring 13 to rotate. Through the reverse rotation of the gear ring 13, the guide block 12 is moved to the side away from the connecting member 3 52, and the hydraulic push rod 514 continues to extend. At this time, it continues to drive the hatch cover body 51 to rotate along the auxiliary shaft 521 until the hatch cover body 51 is opened. The length of the arc guide groove 141 is relatively long, and the distance moved by the guide rod 122 in the arc guide groove 141 can realize the opening and closing of the hatch cover body 51.
