[0033] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] Example 1

[0035] A marine landing device for a ship, such as Figure 1 As shown, it includes a boarding platform 10, a landing frame 20, two telescopic parts 30 and two pressure sensors 40. One end of the boarding platform 10 along the length direction is movably connected to the hull, and the boarding platform 10 can move horizontally or rotate up and down relative to the hull.

[0036] Two telescopic members 30 are spaced apart at the other end of the embarkation platform 10 along the length direction of the embarkation platform 10, and the top of the telescopic member 30 is connected to the embarkation platform 10. The telescopic member 30 can be telescopic along the height direction of the embarkation platform 10. The telescopic member 30 can be an electric telescopic rod, a hydraulic telescopic cylinder, etc.

[0037] The top of the landing frame 20 is connected to the bottom of the telescopic member 30; the landing frame 20 is connected to the boarding platform 10 via two telescopic members 30. The longitudinal cross-section of the landing frame 20 is trapezoidal, and the outer perimeter of the landing frame 20 is a truss structure. The landing frame 20 is made of steel to increase its strength.

[0038] Two pressure sensors 40 are provided at both ends of the bottom of the landing frame 20 along the length direction of the embarkation platform 10 . The two pressure sensors 40 are used to measure the pressure of different areas of the landing frame 20 relative to the landing point.

[0039] like Figure 1 As shown, the length direction of the boarding platform 10 is Figure 1 In the left and right directions of the vehicle, two telescopic members 30 are disposed at the end of the embarkation platform 10 away from the hull, and the landing rack 20 is disposed below the telescopic members 30. The telescopic members 30 adjust the height of the landing rack 20 when they are extended or retracted. Two pressure sensors 40 are disposed at both ends of the bottom of the landing rack 20 to measure the pressure exerted by the landing rack 20 on the landing point. Furthermore, the pressure sensors 40 provide feedback on the progress of the landing rack 20 towards the landing point.

[0040] like Figure 2 As shown, when the embarkation platform 10 lands upward and the landing frame 20 contacts the landing point, the two pressure sensors 40 respectively measure the pressure exerted by the two ends of the landing frame 20 on the landing point. The telescopic lengths of the two telescopic members 30 are adjusted according to the measured pressures, so that the right telescopic member 30 is extended and the left telescopic member 30 is shortened, thereby adjusting the posture of the landing frame 20 and allowing the landing frame 20 to land smoothly, thereby forming a safe passage for construction workers to pass through between the embarkation platform 10 and the landing point.

[0041] like Figure 3 As shown, when the embarkation platform 10 pitches down to land and the landing frame 20 contacts the landing point, the two pressure sensors 40 respectively measure the pressure exerted by the two ends of the landing frame 20 on the landing point. The telescopic lengths of the two telescopic members 30 are adjusted according to the measured pressures, so that the right telescopic rod 30 is shortened and the left telescopic rod 30 is extended, thereby adjusting the posture of the landing frame 20 and making the landing frame 20 land smoothly, thereby forming a safe passage for construction workers to pass through between the embarkation platform 10 and the landing point.

[0042] After the pressure sensor 40 measures the pressure value, the telescopic length of the two telescopic parts 30 can be adjusted manually, or automatically controlled by the controller. When automatic control is performed by the controller, the two telescopic parts 30 and the two pressure sensors 40 are electrically connected to the controller respectively. The controller automatically controls the corresponding telescopic length of each telescopic part 30 according to the measurement value of the pressure sensor 40, thereby realizing automatic adjustment and improving the degree of automation.

[0043] In some embodiments, as Figure 1 As shown, the landing gear 20 is also equipped with a rangefinder 50, located at the bottom of the landing gear 20, for measuring the height between the bottom of the landing gear 20 and the landing point. When the embarkation platform 10 approaches the landing point, the rangefinder 50, mounted on the bottom of the landing gear 20, measures the height between the bottom of the landing gear 20 and the landing point and controls the descent speed of the landing gear 20 based on this height. The rangefinder 50 can be electrically connected to a controller, which controls the descent speed of the landing gear 20 based on the height measured by the rangefinder 50.

[0044] The rangefinder 50 is an infrared rangefinder. A through hole 21 is provided at the bottom of the landing rack 20. The infrared rangefinder is set corresponding to the through hole 21. The infrared rangefinder performs infrared ranging through the through hole 21 at the bottom of the landing rack 20 to measure the vertical distance from the bottom of the landing rack 20 to the landing point surface. The infrared rangefinder is set in the middle position of the bottom of the landing rack 20.

[0045] In some embodiments, as Figure 1 As shown, the offshore landing device further includes a camera 60, which is mounted on the end of the embarkation platform 10 where the telescopic member 30 is located. The camera 60 is electrically connected to the controller. The camera 60 is a 360-degree panoramic camera. When the embarkation platform 10 is in operation, the camera 60 begins to operate, capturing images of the surrounding environment and transmitting the live images to the control terminal. This facilitates controlling the speed of the embarkation platform 10 during its movement and performing obstacle avoidance to prevent the embarkation platform 10 from colliding with obstacles during its movement.

[0046] In some embodiments, as Figure 1 As shown, a rubber pad 70 is provided on the outer side of the bottom of the landing frame 20. The rubber pad 70 can play a role in shock absorption and collision prevention, so that the landing platform 10 is more stable and protects the personal safety of the platform construction workers. Figure 4 As shown, the cross section of the rubber pad 70 is gear-shaped. The outer circumference of the rubber pad 70 is set to be tooth-shaped to prevent the rubber pad 70 from being squeezed and damaged or damaged by the impact of wind and waves at sea.

[0047] In order to ensure that the embarkation platform 10 lands accurately, when using an infrared rangefinder to measure the vertical distance between the landing rack 20 and the landing point, it is necessary to subtract the bottom of the landing rack 20 and the thickness of the rubber pad 70 in advance to make the distance from the landing rack 20 to the landing point more accurate.

[0048] The working principle of the offshore landing device of this embodiment is as follows:

[0049] When the boarding platform 10 lands in an upward-facing position, a camera 60 mounted at the end of the boarding platform 10 monitors the surrounding environment of the boarding platform 10 during its movement and controls the speed of the boarding platform 10 based on the monitoring results. As the landing frame 20 below the boarding platform 10 approaches the landing point, an infrared rangefinder mounted on the inner bottom of the landing frame 20 performs infrared ranging through a through-hole 21 at the bottom of the landing frame 20 and controls the descent speed of the landing frame 20 based on the measurement results. When the landing frame 20 contacts the landing point, two pressure sensors 40 symmetrically mounted on the inner bottom of the landing frame 20 detect pressure. Based on the measurement results of the pressure sensors 40, the controller controls the telescopic member 30 at the right end of the boarding platform 10 to extend and the telescopic member 30 at the left end to shorten, thereby ensuring a smooth landing of the landing frame 20. The pressure sensors 40 provide real-time feedback on the landing progress of the landing frame 20.

[0050] When the embarkation platform 10 descends for a landing, a camera 60 mounted at the end of the platform 10 monitors its surroundings during its movement and controls its speed based on the monitoring mechanism. As the landing frame 20 below the embarkation platform 10 approaches the landing point, an infrared rangefinder mounted on the bottom of the landing frame 20 performs infrared ranging through a through-hole 21 at the bottom of the landing frame 20 and controls the landing speed of the landing frame 20 based on the measurement results. When the landing frame 20 contacts the landing point, two pressure sensors 40 symmetrically mounted on the bottom of the landing frame 20 detect pressure. Based on the measurement results of the pressure sensors 40, the controller controls the telescopic member 30 at the right end of the lower portion of the embarkation platform 10 to shorten and the telescopic member 30 at the left end to lengthen, thereby ensuring a smooth landing of the landing frame 20. The pressure sensors 40 provide real-time feedback on the landing progress of the landing frame 20.

[0051] Example 2

[0052] The difference between this embodiment and the first embodiment is that the number of telescopic rods 30 is different, and the other structures are the same, which will not be described here. In this embodiment, Figure 5 and Figure 6As shown, there are four telescopic members 30, arranged evenly and symmetrically in two rows and two columns below the embarkation platform 10. Arranging multiple rows of telescopic members 30 connected to the landing frame 20 improves the stability of the connection between the landing frame 20 and the embarkation platform 10. When the embarkation platform 10 lands in an upward position, the two telescopic members 30 on the right side extend, while the two telescopic members 30 on the left side shorten. When the embarkation platform 10 lands in a downward position, the two telescopic members 30 on the left side extend, while the two telescopic members 30 on the right side shorten.

[0053] It is understandable that the number of the telescopic members 30 can also be three or more than four, and the number of the telescopic members 30 can be set according to actual usage requirements.

[0054] Example 3

[0055] The difference between this embodiment and the first or second embodiment is the number of pressure sensors 40. The other structures are the same and will not be described in detail here. Figure 6 As shown, there are six pressure sensors 40, which are symmetrically arranged at both ends of the bottom of the landing gear 20, with three pressure sensors 40 arranged at each end. It is understandable that the number of pressure sensors 40 can also be four, five, or more than six. The number of pressure sensors 40 can be set according to actual usage requirements.

[0056] Example 4

[0057] A vessel comprises a hull and the marine landing apparatus for a vessel according to any of the aforementioned embodiments, wherein one end of a boarding platform 10 is movably connected to the hull. When the hull docks, the boarding platform 10 moves, and the length of each telescopic member 30 is adjusted based on the pressure value detected by the pressure sensor 40 at the bottom of the landing frame 20, thereby ensuring that the landing apparatus reaches the landing point smoothly, further improving the degree of automation and precision of the landing apparatus.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
