DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical scheme of the utility model, the utility model will be described in further detail below in conjunction with the drawings and specific embodiments, and it should be explained that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the description of the utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper surface", "lower surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "forward rotation", "reverse rotation", "axial", "radial", "circumferential" and the like is the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.

[0025] As Figure 1As shown, a marine unmanned aerial vehicle platform comprises a protective cabin 1 arranged on a ship deck 3, the protective cabin 1 is divided into five cavities from bottom to top by four partitions 22, one of the cavities is an electric control room 4, and the other cavities are unmanned aerial vehicle parking rooms 5, the entrances of the four unmanned aerial vehicle parking rooms 5 are distributed in front, left, back and right, a support frame 23 is arranged at the entrance 45 of the unmanned aerial vehicle parking room 5, a guide rail 34 is arranged on the partition in the unmanned aerial vehicle parking room 5 and extends outward to the support frame 23, a trolley 35 is arranged on the guide rail 34, and an unmanned aerial vehicle parking bearing plate 2 is arranged on the trolley 35.

[0026] In this embodiment, the unmanned aerial vehicle parking rooms are arranged from bottom to top to save the space occupied by the protective cabin on the ship, and the entrances of the multiple unmanned aerial vehicle parking rooms are distributed in front, left, back and right from bottom to top, which leaves more space for the take-off and landing of the unmanned aerial vehicles, so that multiple unmanned aerial vehicles can be taken off and landed at the same time without affecting each other.

[0027] Since the ship is not static on the sea surface, it will fluctuate with the waves, in order to improve the stability of the unmanned aerial vehicle parking room 5 and facilitate the take-off and landing of the unmanned aerial vehicles, a dynamic real-time leveling device is arranged between the protective cabin 1 and the ship deck 3; the dynamic real-time leveling device comprises four vertically installed electric push rods 37, a levelness sensor 38 and a control unit 39, the bottom of the protective cabin 1 is hinged to the top of the four vertically installed electric push rods 37, the control unit 39 is arranged in the electric control room 4, the levelness sensor 38 is installed on the partition 22, and the control unit 39 dynamically and real-time controls the four electric push rods 37 according to the data information of the levelness sensor 38, so that the partition 22 in the unmanned aerial vehicle parking room 5 is in a horizontal state.

[0028] In order to improve the sensitivity and response speed of the dynamic real-time leveling device, the levelness sensor is installed on the uppermost partition 22, because the higher the shaking is, the more obvious it is.

[0029] A solar panel 40 is arranged on the top of the protective cabin 1, the solar panel 40 charges a storage battery 42 through a power management circuit module 41, and the power management circuit module 41 and the storage battery 42 are arranged in the electric control room 4. Since the ship is moving on the sea, in order to ensure that sunlight can shine on the solar panel 40, the solar panel 40 can be installed horizontally or designed as a spherical structure.

[0030] If necessary, based on the above technical solution, the solar panel 40 can also be installed on the sun-facing adjustment mechanism 43. The sun-facing adjustment mechanism 43 is used to adjust the orientation and tilt angle of the solar panel so that it always faces the sun. In this embodiment, the sun-facing adjustment mechanism 43 uses a horizontal rotating motor to drive the solar panel 40 to turn horizontally to adjust its orientation, and a flipping motor to drive the solar panel 40 to flip vertically to adjust its tilt angle, ensuring that the solar panel 40 automatically and always faces the sun to improve sunlight utilization. Since the sun-facing adjustment mechanism 43 is existing technology, it will not be described in detail further.

[0031] Lighting lights 36 are installed around the top of the protective cabin 1 to facilitate the take-off and landing of drones at night.

[0032] like Figure 2 As shown, the surface of the drone parking support plate 2, near its rear and front sides, is provided with elongated rear sliding holes 6 and elongated front sliding holes 7, respectively. The elongated rear sliding hole 6 houses a rear slider A8 and a rear slider B9, and the elongated front sliding hole 7 houses a front slider A10 and a front slider B11. Above the drone parking support plate 2, there are transverse positioning rods A12 and B13. The two ends of the transverse positioning rod A12 are fixed to the rear slider A8 and the front slider A10, respectively, and the two ends of the transverse positioning rod B13 are fixed to the rear slider B9 and the front slider B11, respectively. The surface of the drone parking support plate 2, near its left and right sides... The device is equipped with elongated left sliding holes 14 and right sliding holes 15. Left sliding holes 14 house left sliders A16 and B17, while right sliding holes 15 house right sliders A18 and B19. Above the drone parking support plate 2 are longitudinal positioning rods A20 and B21. The two ends of longitudinal positioning rod A20 are fixed to the left slider A16 and right slider A18, respectively, and the two ends of longitudinal positioning rod B21 are fixed to the left slider B17 and right slider B19, respectively. The longitudinal positioning rods A20 and B21 are located above the transverse positioning rods A12 and B13. In this embodiment, two longitudinal positioning rods and two transverse positioning rods are installed, enabling precise positioning of the drone.

[0033] like Figure 3As shown, the lower surface of the unmanned aerial vehicle parking bearing plate 2 is provided with a servo motor 24 and a transmission mechanism. Specifically, the transmission mechanism includes a rear lead screw 25, a front lead screw 26, a left lead screw 27 and a right lead screw 28. Threaded segments A and B with opposite thread directions are arranged on the rear lead screw 25, the front lead screw 26, the left lead screw 27 and the right lead screw 28. The servo motor 24 is connected to one end of the rear lead screw 25 through a shaft coupling 29. The other end of the rear lead screw 25 is connected to one end of the right lead screw 28 through a bevel gear set. The other end of the right lead screw 28 is connected to one end of the front lead screw 26 through a bevel gear set. The other end of the front lead screw 26 is connected to one end of the left lead screw 27 through a bevel gear set. The rear sliding blocks A8 and B9 are respectively installed on the threaded segments A and B of the rear lead screw 25 through nuts. The front sliding blocks A10 and B11 are respectively installed on the threaded segments A and B of the front lead screw 26 through nuts. The left sliding blocks A16 and B17 are respectively installed on the threaded segments A and B of the left lead screw 27 through nuts. The right sliding blocks A18 and B19 are respectively installed on the threaded segments A and B of the right lead screw 28 through nuts. The above-mentioned transmission mechanism has a simple structure. A single driving source can realize the overall operation of the mechanism. The mechanical structure ensures the stability of the movement, thereby reducing the cost and improving the reliability of the unmanned aerial vehicle platform.

[0034] The servo motor 24 drives the rear sliding blocks A8 and B9, the front sliding blocks A10 and B11, the left sliding blocks A16 and B17 and the right sliding blocks A18 and B19 through the transmission mechanism to drive the transverse positioning rods A and B to move towards each other and drive the longitudinal positioning rods A and B to move towards each other, thereby pushing the unmanned aerial vehicle to position the unmanned aerial vehicle at the center of the unmanned aerial vehicle parking bearing plate 2. A wireless charging plate 44 is arranged at the center of the unmanned aerial vehicle parking bearing plate 2. When the servo motor rotates, the front lead screw and the rear lead screw rotate in opposite directions, and the left lead screw and the right lead screw rotate in opposite directions. The sliding blocks connected to the two ends of the same positioning rod move in the same direction, i.e. the sliding blocks will simultaneously press or stretch the positioning rod in the direction of the positioning rod, thereby ensuring that the two sliding blocks will not have relative angular displacement relative to the bearing top plate, and ensuring that the sliding blocks and the bearing top plate will not contact and rub. That is, when the servo motor outputs torque in different directions, the sliding blocks will not shake left and right.

[0035] As shown in Figure 4 The rear sliding blocks A8 and B9, the front sliding blocks A10 and B11, the left sliding blocks A16 and B17 and the right sliding blocks A18 and B19 have the same structure. The rear sliding block A8 is provided with a through hole 30. A nut 31 is arranged in the through hole 30. One end of the nut 31 is provided with a flange 32. The flange 32 is fixed to the side surface of the rear sliding block A8 through a screw 33.
