DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4 A take-off and landing platform for a surveying and mapping UAV includes a take-off and landing platform 1. The take-off and landing platform 1 is provided with a positioning mechanism having a positioning plate 7 positioning function. The positioning mechanism includes a connecting plate 5 and a threaded column 8. The connecting plate 5 is fixedly connected to a rotating shaft 6. The rotating shaft 6 is rotatably connected to the positioning plate 7. The positioning plate 7 is threadedly connected to the threaded column 8. For UAVs with a larger weight and higher stability requirements, the following figure can be used. Figure 1 The threaded column 8 is threadedly connected to the fixed support in the threaded hole 100, making the structure of the take-off and landing platform 1 more solid and ensuring that the UAV remains stable during take-off and landing;

[0021] It also includes a triangular support frame 9, on which a lifting mechanism with a lifting function of a threaded rod 10 is provided. The lifting mechanism includes a ground contact plate 1000 and a crank handle 1001. The top and bottom of the threaded rod 10 are fixedly connected to the ground contact plate 1000 and the crank handle 1001 respectively.

[0022] In this embodiment, a fixed disk 3 is further included. Six connecting plates 5 are fixedly connected to the outer circumferential wall of the fixed disk 3 in an annular array. A rotating shaft 6 is fixedly connected between two adjacent connecting plates 5 .

[0023] In this embodiment, three threaded holes 100 are opened in a circular array on the circumferential outer wall of the lifting platform 1, and a threaded hole 2 70 is horizontally passed through the top of the positioning plate 7. A threaded column 8 is threadedly connected to the threaded hole 2 70 and extends into the threaded hole 100.

[0024] In this embodiment, a plurality of shock absorbers 2 are installed between the fixed plate 3 and the lifting platform 1 . A level placement groove 30 is provided on the fixed plate 3 , and a level 4 is placed in the level placement groove 30 .

[0025] In this embodiment, the bottom surface of the fixed plate 3 is fixedly connected to a triangular support frame 9, and three threaded holes 90 are opened on the triangular support frame 9. The threaded holes 90 are threadedly connected to the threaded rods 10, and the crank 1001 is in contact with the ground.

[0026] The use method and advantages of this utility model: When the drone is in use, the working process is as follows:

[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, when a heavy drone with high stability requirements needs to take off and land on the take-off and landing platform 1, the operator can flip the originally lowered positioning plate 7 upward to make the positioning plate 7 fit the circumferential outer wall of the take-off and landing platform 1, and then screw the threaded column 8 into the second threaded hole 70 and the first threaded hole 100 in sequence to fix the positioning plate 7 in the position of the take-off and landing platform 1, thereby preventing the shock absorber 2 provided on the fixing plate 3 from causing the drone to take off and land unstable. At the same time, when bad weather occurs, the threaded column 8 is unscrewed to make the positioning plate 7 fall. At this time, the shock absorber 2 plays a buffering role. Through the above description, the take-off and landing platform 1 can adjust the support mode to make the platform fixed to meet the take-off and landing requirements of different drones.

[0028] When the device is used for taking off and landing drones in farmland, due to the uneven road surface in the field, in order to place the device stably, the operator can first remove the level 4 from the level placement slot 30, and then place it on the fixed plate 3, and adjust the threaded rod 10 through the level 4. The adjustment process is as follows:

[0029] When the level ruler 4 shows that one side is lower, the operator can rotate the crank 1001 clockwise to extend the threaded rod 10 downward in the threaded hole 3 90, thereby increasing the height of the triangular support frame 9 on the falling side. Otherwise, rotate the crank 1001 counterclockwise. Through the above description, the problem of reduced safety of the drone's take-off and landing due to the tilt of the take-off and landing platform 1 during the take-off and landing of the drone on the take-off and landing platform 1 can be avoided, thereby reducing the problem of damage to the internal structure of the drone due to unstable take-off and landing.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
