Description

Technical Field

[0001] This utility model relates to the field of marine unmanned aerial vehicle (UAV) technology, and more specifically, to a marine UAV take-off and landing cabin. Background Technology

[0002] Offshore wind power maintenance vessels typically carry drones. In high-risk working environments that are inaccessible or difficult for personnel to reach, drones are often used for inspections and other operations, greatly improving work efficiency. However, the drones on these vessels spend most of their time on the deck's parking platform, making them highly susceptible to corrosion from seawater and sunlight, leading to electronic component malfunctions. Furthermore, the harsh marine environment causes drones to sway during takeoff and landing due to waves, preventing stable takeoffs and landings and increasing the risk of accidents.

[0003] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] A preferred embodiment of this utility model provides a take-off and landing cabin for a maritime unmanned aerial vehicle (UAV), such as... Figure 1 As shown, it includes a square base 1, which is made of stainless steel plate and is fixedly installed on the deck of the mother ship. The square base 1 has movable hatch cover structures symmetrically arranged on the left and right sides, and movable hatch panel structures symmetrically arranged on the front and rear sides.

[0025] Taking the movable hatch structure on the left side of the square base 1 as an example, specifically, it includes a hatch body and a first electric push rod 2. The hatch body is L-shaped and is composed of a vertical plate 3 and a horizontal plate 4. A first rotating shaft is fixedly installed at the bottom end of the vertical plate 3 along the front-to-back direction. Two first hinge bushings are arranged at intervals on the left side of the square base 1. The front and rear ends of the first rotating shaft are rotatably connected to the corresponding first hinge bushings, and the end of the horizontal plate 4 faces the right side of the base. The fixed end of the first electric push rod 2 is hinged to the upper surface of the square base 1, and the telescopic end is hinged to the middle position of the vertical plate 3. Based on the above configuration, the extension and retraction of the first electric push rod 2 can drive the hatch body to rotate left and right about the first rotating shaft.

[0026] The structure of the movable hatch on the right side of the square base 1 is the same as described above, and will not be repeated here.

[0027] Taking the movable compartment structure on the front side of the square base 1 as an example, specifically, it includes a cover plate 5 and a second electric push rod 6. A second rotating shaft is fixedly installed at the bottom end of the cover plate 5 along the left-right direction. Two second hinge bushings are arranged at intervals on the left and right sides of the front side of the square base 1. The left and right ends of the second rotating shaft are rotatably connected to the corresponding second hinge bushings. The fixed end of the second electric push rod 6 is hinged to the upper surface of the square base 1, and the telescopic end is hinged to the middle position of the cover plate 5. Based on the above configuration, the extension and retraction of the second electric push rod 6 can drive the cover plate to rotate back and forth about the second rotating shaft.

[0028] The structure of the movable compartment on the rear side of the square base 1 is the same as described above, and will not be repeated here.

[0029] A controller (not shown in the figure) is also installed on the square base 1. Two first electric push rods 2 and two second electric push rods 6 are electrically connected to the controller. When the controller controls the two first electric push rods 2 to retract and rotate the corresponding cover body until the vertical plate 3 is perpendicular to the square base 1, at the same time, the controller controls the two second electric push rods 6 to retract and rotate the corresponding cover plate 5 to be perpendicular to the square base 1. At this time, the square base 1, the two covers, and the two cover plates 5 form a sealed hollow chamber. It should be noted that the hollow chamber is not completely sealed at this time. Of course, when the controller controls the two first electric push rods 2 and the two second electric push rods 6 to extend, the hollow chamber opens.

[0030] The hollow cabin is equipped with a landing platform 7 located above the square base 1. The landing platform 7 has a disc-shaped structure, and a wave compensation support device is provided between the square base 1 and the landing platform 7.

[0031] like Figure 2 As shown, the wave compensation support device includes six third electric push rods 8 arranged circumferentially. Any two adjacent third electric push rods 8 are arranged at an angle relative to each other. The fixed end of each third electric push rod 8 is hinged to the upper surface of the square base 1, and the telescopic end is hinged to the lower surface of the lifting platform 7. When the lifting platform 7 is parallel to the square base 1, any two adjacent third electric push rods 8 can form an isosceles triangle structure with one of the square base 1 and the lifting platform 7. All six third electric push rods 8 are electrically connected to the controller.

[0032] The wave compensation support device also includes an inertial navigation sensor (not shown in the figure), which is installed in the middle of the square base 1 and is electrically connected to the controller.

[0033] During the take-off and landing of the UAV on the take-off and landing platform, when the sea surface rises and falls, the inertial navigation sensor will collect the changes in the tilt angle of the deck as the sea level rises and falls, and convert them into extension and retraction control data of the electric push rod. The data is then transmitted to the controller, which controls the extension and retraction of the corresponding electric push rod to keep the take-off and landing platform in a horizontal state.

[0034] Furthermore, the take-off and landing platform 7 is equipped with charging equipment for charging the drone (not shown in the figure).

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
