[0029] The utility model will be further described below in conjunction with the accompanying drawings.

[0030] See also Figure 1-Figure 4 A marine UAV take-off and landing platform comprises a platform base 1, a rotating platform device 2 and two relatively arranged mobile clamping devices 3 on the left and right. The rotating platform device 2 comprises a rotating platform 200 rotatably mounted on the platform base 1 and a rotating driving mechanism 201 for driving the rotating platform 200 to rotate. The mobile clamping device 3 is arranged on the rotating platform 200, and comprises a clamping claw 300, a clamping claw rotation driving mechanism 301 and a clamping claw translation driving mechanism. The clamping claw 300 is an arc plate-shaped structure, which is used to clamp the landing gear 4 of the UAV. The clamping claw rotation driving mechanism 301 is a reduction motor, which drives the clamping claw 300 to rotate, and the clamping claw translation driving mechanism drives the clamping claw 300 to translate, thereby adjusting the spacing between the clamping claws 300 on both sides.

[0031] Continue reading Figure 3 The platform base 1 of the utility model has an inner cavity, and a groove is provided above the inner cavity. The inner diameter of the groove is larger than the inner diameter of the inner cavity. The rotating platform 200 is rotatably installed in the groove through a bearing. The rotating drive mechanism 201 is located in the inner cavity. The rotating drive mechanism 201 adopts a worm gear reducer, and its output shaft is connected to the center of the rotating platform 200, which can directly drive the rotating platform 200 to rotate. The upper surface of the rotating platform 200 is provided with an installation cavity 2000 for installing the mobile clamping device 3.

[0032] Continue reading Figure 4The mobile clamping device 3 also includes a slide 302 for supporting the landing gear 4 of the UAV. The slide 302 slides with the rotating platform 200 along the left and right directions. The clamp 300 is rotatably installed on the slide 302, and the clamp rotation driving mechanism 301 is fixedly installed on the slide 302.

[0033] The front and rear sides of the slide seat 302 are respectively provided with slide rails 304, and the inner wall of the rotating platform 200 is provided with corresponding sliders 303. The slide rails 304 are laid along the left and right directions, and the sliders 303 slide in cooperation with the slide rails 304. In addition, the positions of the slide rails 304 and the sliders 303 can be interchanged.

[0034] Further reading Figure 4 The jaw translation drive mechanism includes a gear 305, a rack 306 and a translation motor. The rack 306 is arranged in the left and right directions and is fixedly connected to the slide rail 304. The gear 305 is rotatably installed in the rotating platform 200 and meshes with the rack 306. The translation motor is a reduction motor, which is fixed and hidden in the inner wall of the rotating platform 200, and drives the gear 305 to rotate.

[0035] When the clamping jaw translation driving mechanism is working, the translation motor drives the gear 305 to rotate, and the gear 305 drives the rack 306 and the slide 302 to move left and right.

[0036] In the present invention, each mobile clamping jaw device 3 includes two front and rear clamping jaw translation driving mechanisms, which cooperate with the front and rear sides of the slide seat 302 respectively.

[0037] In some embodiments, the gears 305 of the two jaw translation drive mechanisms in each mobile jaw device 3 can be installed on the same shaft and driven to rotate by a translation motor.

[0038] Furthermore, an electromagnet for fixing and absorbing the landing gear 4 of the UAV is arranged on the slide seat 302 .

[0039] When the utility model is used, when the UAV flies above the utility model, the rotary drive mechanism 301 drives the rotating platform 300 to rotate and position according to the position of the UAV. After the UAV lands on the rotating platform 200, the rotary drive mechanism 301 drives the clamp 300 to rotate to a closed state (the clamp 300 is initially in an open state), and the clamp 300 locks the landing gear 4 of the UAV on the slide 302. Then the electromagnet is energized to attract the landing gear 4, and the UAV is firmly fixed on the rotating platform 200 through the clamp 200 and the electromagnet.

[0040] When encountering drones of different widths, the utility model can adjust the position of the clamping jaw 300 through the clamping jaw translation drive mechanism, thereby adjusting the spacing of the clamping jaw 300 to adapt to drones of different widths.

[0041] It should be noted that the utility model is used in conjunction with an intelligent control system, a camera, and a wireless transmission module. The camera observes the situation of the drone, the wireless transmission module realizes remote information transmission and control, and the intelligent control system is responsible for information processing and controlling the work of each mechanism. The entire operation process can be simplified, and the operator only needs to perform simple operations, and the system can automatically adapt to different situations, reducing the complexity of the operation and improving the operation efficiency.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
