Description

Technical Field

[0001] This utility model relates to the field of start-stop correction equipment, specifically a start-stop correction device for unmanned aerial vehicles (UAVs). Background Technology

[0002] Drones play an important role in aerial surveying and mapping. Aerial photography technology is an important means of image acquisition. When changing batteries, drones need to land on the helipad of the battery swapping station. Although the landing coordinates can be preset to make the drone land on the helipad, the drone's position after landing may not be very accurate. If the drone's position is not corrected, the battery cannot be removed. Therefore, it is necessary to adjust and correct the drone's position.

[0003] According to a patent document with publication number CN220243570U, a drone start-stop correction device includes a landing pad. A first correction device, a second correction device, a third correction device, and a fourth correction device are arranged on the upper part of the landing pad. The first and second correction devices have identical structures and are symmetrically arranged. The third and fourth correction devices also have identical structures and are symmetrically arranged. In use, this technical solution uses a dual-axis stepper motor to synchronously and accurately move the drone to the parking area. However, while this solution achieves the movement of the drone, it cannot provide storage and protection for the drone when it is not in use, which is inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a drone start-stop correction device to solve the problems mentioned in the background. This invention has a novel structure. In use, the rotating movable cylinder moves the fixed plate to the bottom of the support base. The threaded column pushes the support base and the fixed plate to move and complete the descent of the movable cylinder. After descent, the space between the fixed base and the movable cylinder is increased, allowing the drone to be stored and protected between the movable cylinder and the fixed base.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for correcting the start and stop of a drone, comprising a fixed base, a motor base welded to the top of the fixed base, a dual-axis motor fixedly installed inside the motor base, a threaded column mounted on the dual-axis motor, a fixed block and a support block movably mounted on the threaded column, a fixed rod welded between the fixed blocks, a support rod welded between the support blocks, the support rod and the fixed rod being vertically staggered, and an opening on the fixed base, inside which a support plate is movably installed.

[0006] Furthermore, a threaded seat is welded onto the fixed base, a threaded rod is rotatably mounted inside the threaded seat, a support seat is rotatably mounted at one end of the threaded rod, and a fixing hole is opened at the bottom of the support seat.

[0007] Furthermore, the fixed base has a sliding groove, and a slider is movably installed inside the sliding groove. The slider is fixedly installed at the bottom of the support block and the fixed block respectively.

[0008] Furthermore, a slot is provided on the side of the fixing base, and a bubble level is fixedly installed inside the slot.

[0009] Furthermore, a rotating seat is movably installed inside the opening, a limit block is welded to the side of the rotating seat, and a limit groove is formed on the inner wall of the opening.

[0010] Furthermore, the limiting block is installed inside the limiting groove by a support mechanism, and a movable cylinder is movably installed at the bottom of the rotating seat.

[0011] Furthermore, a fixing plate is welded to the side of the movable cylinder, and a fixing column is fixed on the fixing plate.

[0012] Furthermore, a lifting mechanism is fixedly installed inside the movable cylinder, and one end of the lifting mechanism is fixed to the support plate.

[0013] The beneficial effects of this utility model are:

[0014] This device is used for drone start-stop correction. When in use, the rotating cylinder moves the fixed plate to the bottom of the support base. The threaded column pushes the support base and the fixed plate to move and complete the descent of the rotating cylinder. After descent, the space between the fixed base and the rotating cylinder is increased, allowing the drone to be stored and protected between the rotating cylinder and the fixed base.

[0015] This device is used for drone start-stop correction. It uses a dual-axis motor to drive a threaded column to rotate, which in turn drives a fixed block and a support block to move. When the support block and the fixed block move, the support rod and the fixed rod push the drone to move on the support plate to adjust its landing point.

[0016] This device is used for drone start-stop correction. The threaded rod pushes the support base to move downward. By moving the support base up and down at different positions, the level of the fixed base is adjusted according to the flatness of the ground. The level of the fixed base is observed and adjusted by a bubble level. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a device for correcting the start and stop of a drone, including a fixed base 1, a motor base 9 welded to the top of the fixed base 1, a dual-axis motor 10 fixedly installed inside the motor base 9, a threaded column 11 installed on the dual-axis motor 10, a fixed block 12 and a support block 13 movably installed on the threaded column 11, a fixed rod 15 welded between the fixed blocks 12, a support rod 14 welded between the support blocks 13, the support rod 14 and the fixed rod 15 being vertically staggered, an opening 16 on the fixed base 1, a support plate 17 movably installed inside the opening 16, a threaded seat 6 welded to the fixed base 1, a threaded rod 7 rotatably installed inside the threaded seat 6, a support seat 8 rotatably installed at one end of the threaded rod 7, a fixing hole 25 at the bottom of the support seat 8, a fixing column 5 later installed inside the fixing hole 25, the fixing hole 25 providing a limiting support point for the fixing column 5, thereby completing the limiting and fixing of the position of the movable cylinder 20 and the fixing plate 4.

[0025] In this embodiment, the fixed base 1 has a sliding groove 18, and a slider 19 is movably installed inside the sliding groove 18. The slider 19 is fixedly installed at the bottom of the support block 13 and the fixed block 12 respectively. The fixed base 1 has a slot 2 on its side, and a bubble level 3 is fixedly installed inside the slot 2. A rotating base 21 is movably installed inside the opening 16. A limit block 22 is welded to the side of the rotating base 21, and a limit groove is opened on the inner wall of the opening 16. The level of the fixed base 1 is adjusted by the bubble level 3. After the fixed base 1 is leveled, it provides a stable support platform for the take-off and landing of the UAV.

[0026] In this embodiment, the limiting block 22 is installed inside the limiting groove by the support mechanism 23. The bottom of the rotating seat 21 is movably installed with a movable cylinder 20. A fixing plate 4 is welded to the side of the movable cylinder 20. A fixing column 5 is fixed on the fixing plate 4. A lifting mechanism 24 is fixedly installed inside the movable cylinder 20. One end of the lifting mechanism 24 is fixed to the support plate 17. The lifting mechanism 24 is a linear reciprocating electric push rod. The lifting mechanism 24 pushes the support plate 17 to move up and down. After the top of the support plate 17 is flush with the fixed seat 1, it provides a flat support point for the movement of the UAV.

[0027] When using the device, the fixed base 1 is placed in the operating position. The threaded rod 7 is rotated to push the support base 8 into contact with the ground. The height distribution of the threaded base 6 at different positions is adjusted according to the ground level. The level of the fixed base 1 is adjusted by the support adjustment of the support base 8 and the bubble level 3. The UAV uses the preliminary aerial survey data constructed by the digital twin water conservancy data base plate to meet the needs of the survey. When the UAV needs to land on the fixed base 1, the dual-axis motor 10 is started to drive the threaded column 11 to rotate. The threaded column 11 is a bidirectional thread. The threaded column 11 drives the fixed block 12 and the support block 13 to move outward at the same time. The support rod 14 and the fixed rod 15 open the space at the center of the fixed base 1. After the UAV lands on the fixed base 1, the dual-axis motor 10 is started to drive the support rod 14 and the fixed rod 15 to move inward at the same time. When moving inward, the support rod 14 and the fixed rod 15 contact the UAV. The movement of the support rod 14 and the fixed rod is selected according to the adjustment of the UAV left, right and forward and backward. Position 15 pushes the drone to complete the start-stop calibration. After the drone moves to the designated location, the support rod 14 and the fixing rod 15 clamp and fix the sides of the drone. When the drone is used for surveying, the lifting mechanism 24 is activated to drive the support plate 17 to move downward and retract into the interior of the movable cylinder 20. The drone enters the interior of the movable cylinder 20 along with the support plate 17. The movable cylinder 20 is rotated so that the fixing post 5 at one end of the fixing plate 4 enters the bottom of the support base 8. The threaded rod 7 pushes the support base 8 downward. When the support base 8 moves downward, the fixing plate 4 drives the movable cylinder 20 downward. The limiting block 22 completes the compression of the support mechanism 23. The downward movement of the movable cylinder 20 cooperates with the opening 16 on the fixed base 1 to provide sufficient space for storing the drone. After the drone is placed inside the opening 16, the support rod 14 and the fixing rod 15 move to the top of the opening 16 to limit the top of the drone, so that the drone and the fixed base 1 can be combined and stored, which is convenient for carrying and moving as a whole later.
