[0031] Working principle: the control center is fixedly connected in the fixed bin 10, in the initial state, the user can open the first linear drive assembly 30 through the control center to adjust the extension size of the first output rod 300 according to the inclination degree of the current landing point, so as to control the support angle of the gangway device 3, then the electric push rod is opened by the control center, the electric push rod is opened to push out and extend the gangway 31 to the landing point, in this process, the third linear drive assembly 44 is opened by the control center, the third linear drive assembly 44 pushes out and moves the third output rod 440, the movement of the third output rod 440 drives the floating assembly 45 to move downward until the floating assembly 45 contacts with the sea surface and floats on the sea surface, when the waves on the sea surface impact the ship, the distance between the ship and the right landing point becomes larger, the waves impact the ship and also impact the floating assembly 45 and make it move, the floating assembly 45 moves through the third output rod 440, the third linear drive assembly 44, the fixed part 433, drives the second adjusting plate 432 to move left, the movement of the second adjusting plate 432 drives the two second tooth plates 431 to move left, the movement of the second tooth plate 431 drives the tooth disc 430 to rotate, the rotation of the tooth disc 430 drives the first tooth plate 414 to move right, the movement of the first tooth plate 414 drives the first adjusting plate 412 to move, the compensation ladder plate 41 is initially stored in the gangway 31, when the first adjusting plate 412 moves right, the compensation ladder plate 41 is stretched out from the gangway 31 through the second telescopic plate 411 and the sliding plate 410, the compensation ladder plate 41 is stretched out and moves towards the right landing point, thereby compensating for the distance of the gangway device 3 and the gangway 31 after being pushed by the waves, and in this period of time, the user is still moving on the top of the gangway device 3, so that the movement of the compensation ladder plate 41 at this time will not affect the user, and the movement of the first adjusting plate 412 drives the plurality of clamping blocks 413 to move, because the right end of the clamping block 413 is arc-shaped, it can be clamped in the clamping groove through the elastic deformation of the elastic member when the first adjusting plate 412 moves, when the waves become larger, the clamping block 413 can continue to move and change the clamping position, when the waves decrease, the straight structure at the left end of the clamping block 413 can avoid the movement of the compensation ladder plate 41 through the sliding plate 410 and the second telescopic plate 411 when the first adjusting plate 412 resets, which may cause the risk of falling of the personnel on the compensation ladder plate 41, when all the personnel land, the second linear drive assembly 400 is opened to drive the second output rod 401 to move upward, because the compensation ladder plate 41 is slidingly connected to the top inner wall of the gangway 31, the compensation ladder plate 41 can play a certain limiting role at this time, the second output rod 401 moves through the mounting plate 40 to drive the top plate 42 to move upward as a whole, the second telescopic plate 411 separates from the sliding plate 410 at this time, and the clamping block 413 is separated from the clamping groove, and the sliding plate 410 and the second telescopic plate 411 can also ensure that the device reserves a certain space for the movement of the top plate 42,The device can be reset normally with the impact of waves. The device can automatically compensate the distance of the stretched ladder plate according to the size of the waves, thereby improving the safety protection effect of the device and facilitating user use. When the waves hit the ship and some seawater splashes into the gangway device 3 and stretches the inside of the gangway 31, the control center is used to open the two first rotary drive components 320 and the two second rotary drive components 330. The first rotary drive component 320 is turned on to drive the first screw 322 to rotate through the first rotating shaft 321. The first screw 322 rotates to drive the movable block 323 to move. The movable block 323 moves and drives the processing chamber 33 to move through the sliding rod 324. In this process, the second rotary drive component 330 is turned on to drive The second rotating shaft 331 rotates, and the second rotating shaft 331 rotates to drive the adjusting arm 332 to rotate. The adjusting arm 332 rotates to drive the return groove plate 334 to perform linear reciprocating motion through the movable rod 333. The movable plate 335 and the first telescopic plate 336 are used to limit the movement of the return groove plate 334. The movement of the return groove plate 334 drives the two movable plates 335 to move. The movement of the movable plate 335 drives the cleaning plate 338 to perform linear reciprocating motion at the gangway device 3 and the stretching gangway 31 through the through rod 337. The movement of the cleaning plate 338 makes it The splashing seawater can be cleaned, and the movable block 323 drives the processing chamber 33 to move so that the cleaning plate 338 can fully clean the surface of the gangway device 3 and the stretching gangway 31, so as to avoid the situation that the waves splashing onto the surface of the gangway device 3 and causing the surface to become wet and the user to slip when the user disembarks. When the user enters the gangway device 3 through the fixed chamber 10 and enters the stretching gangway 31 through the gangway device 3, when the passenger flow is small, the user can stand at the processing chamber 33 on the top of the gangway device 3. At this time, the user can go up The processing bin 33 makes a linear motion on the top of the gangway device 3 to assist in moving to the stretching gangway 31. During this process, the user can hold the first guardrail to ensure a certain degree of safety. After the user reaches the stretching gangway 31, the processing bin 33 there is used to assist in going ashore. When the passenger flow is large, the user can choose not to stand on the top of the processing bin 33 to be assisted by the processing bin 33. At this time, the movement of the processing bin 33 only cleans the gangway device 3 and the top of the stretching gangway 31, thereby improving the safety protection effect of the device and facilitating user use.
