Description

Technical Field

[0001] This utility model belongs to the field of UAV remote sensing measurement technology, specifically relating to a mobile platform for UAV remote sensing measurement. Background Technology

[0002] During engineering surveys, in order to obtain detailed remote sensing data of a certain area, drones are often used to collect remote sensing data of low-altitude areas. Due to the limited flight distance and control range of drones, in actual surveys, drones are often transported to the area to be surveyed, launched into the air using a dedicated drone launcher, and the remote sensing data measured by the drone is collected through a dedicated receiving device. Currently, most drones are transported directly by freight trucks.

[0003] Currently, existing engineering surveying drone remote sensing mobile platforms are not convenient for securing drones properly, and they are prone to shaking during transportation, which can easily lead to damage to the drones.

[0004] Moreover, existing mobile drone platforms need to be measured in the field, and the ground in some areas is often uneven. When the platform is unfolded and placed, the uneven ground will prevent the take-off platform itself from being placed flat, causing the drone to fail to take off or land or to be prone to collisions.

[0005] Therefore, we propose a mobile platform for UAV remote sensing measurement to solve the above problems. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a mobile platform for UAV remote sensing measurement. A leveling mechanism supports and adjusts the takeoff platform, allowing it to rotate on the lifting platform. A level gauge, in conjunction with the platform's level, ensures the platform is horizontally level, preventing takeoff and landing failures or collisions due to unevenness. A clamping and securing mechanism ensures the UAV is securely held in place, preventing damage during transport due to shaking.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mobile platform for remote sensing measurement of unmanned aerial vehicles (UAVs), including a mobile carrier vehicle, on which a storage and protection box is mounted. Inside the storage and protection box, a lifting platform is connected to the UAV via a hydraulic lifting rod. A takeoff platform is rotatably connected to one end of the lifting platform via a rotating shaft seat. The lifting platform is provided with a leveling mechanism for adjusting the horizontal level of the takeoff platform, and a clamping and fixing mechanism for limiting and fixing the UAV is installed on the takeoff platform.

[0008] As a preferred embodiment, the leveling mechanism includes a lead screw installed in the mounting groove of the lifting platform, a lead screw slide seat slidably mounted on the lead screw, an adjusting arm hinged to the lead screw slide seat via a hinge seat, the other end of the adjusting arm being hinged to the bottom of the other end of the take-off platform, and a lead screw motor connected to the lead screw drive being provided in the mounting groove.

[0009] As a preferred embodiment, the clamping and fixing mechanism includes a bidirectional reciprocating lead screw installed in a groove in the takeoff platform. Both ends of the bidirectional reciprocating lead screw are connected to clamping plates via lead screw sliders and connecting rods. Several telescopic clamping rods are provided on the inner side of the clamping plates. Clamping blocks are provided on the telescopic clamping rods. Compression springs connected to the clamping plates and clamping blocks are sleeved on the telescopic clamping rods. A second motor that is driven and connected to the bidirectional reciprocating lead screw is installed on the side wall of the takeoff platform.

[0010] As a preferred embodiment, the inner wall of the storage and protection box is provided with a sliding groove, and the two sides of the lifting platform slide within the sliding groove via guide sliders; the top of the storage and protection box is connected to a box lid via hinges, and handles are provided on the two side walls of the storage and protection box.

[0011] As a preferred embodiment, the bottom of the mobile carrier is equipped with mobile rollers.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figure 1-5 This utility model provides the following technical solution: a mobile platform for remote sensing measurement of unmanned aerial vehicles (UAVs), including a mobile carrier vehicle 1. A storage and protection box 2 is mounted on the mobile carrier vehicle 1. A lifting platform 4 is connected to the inside of the storage and protection box 2 via a hydraulic lifting rod 3. The lifting platform 4 is driven by the hydraulic lifting rod 3 to lift the UAV out or store it in the storage and protection box 2. A takeoff platform 5 is rotatably connected to one end of the lifting platform 4 via a pivot seat 41. The lifting platform 4 is equipped with a leveling mechanism 7 for adjusting the levelness of the takeoff platform 5. The leveling mechanism 7 supports and adjusts the takeoff platform 5, allowing it to rotate on the lifting platform 4 via the pivot seat 41. In conjunction with a level gauge, the levelness of the takeoff platform 5 is adjusted to avoid takeoff and landing failures or collisions caused by unevenness of the takeoff platform 5. A clamping and fixing mechanism 6 for limiting and fixing the UAV is installed on the takeoff platform 5. The clamping and fixing mechanism 6 facilitates the proper fixing of the UAV, preventing shaking during transportation and avoiding damage to the UAV.

[0023] Specifically, the leveling mechanism 7 includes a lead screw 71 installed in the mounting groove of the lifting platform 4. A lead screw slide 73 is slidably mounted on the lead screw 71. An adjusting arm 74 is hinged to the lead screw slide 73 via a hinge seat. The other end of the adjusting arm 74 is hinged to the bottom of the other end of the takeoff platform 5. A lead screw motor 72, which is driven and connected to the lead screw 71, is installed in the mounting groove. In use, the lead screw motor 72 drives the lead screw 71 to rotate, which in turn drives the adjusting arm 74 to move via the lead screw slide 73. During the movement of the adjusting arm 74, one end of the takeoff platform 5 is supported and adjusted, so that the other end of the takeoff platform 5 rotates on the lifting platform 4 via the pivot seat 41. This, in conjunction with a level gauge, achieves level adjustment of the takeoff platform 5, preventing the drone from being unable to be placed flat on the takeoff platform 5 due to uneven ground, and preventing takeoff and landing failures or collisions caused by the unevenness of the takeoff platform 5.

[0024] Specifically, the clamping and fixing mechanism 6 includes a bidirectional reciprocating lead screw 61 installed in a groove in the takeoff platform 5. Both ends of the bidirectional reciprocating lead screw 61 are connected to clamping plates 64 via lead screw sliders and connecting rods 63. Several telescopic clamping rods 65 are provided on the inner side of the clamping plates 64. Clamping blocks 66 are provided on the telescopic clamping rods 65, and compression springs 67 connected to the clamping plates 64 and clamping blocks 66 are sleeved on the telescopic clamping rods 65. A second motor 62, which is driven and connected to the bidirectional reciprocating lead screw 61, is installed on the side wall of the takeoff platform 5. Rubber pads are provided on the surface of the clamping blocks 66. In use, the second motor 62 is started to drive the bidirectional reciprocating lead screw 61 to rotate, which in turn drives the clamping plates 64 to move in opposite directions via the lead screw sliders. This causes the clamping blocks 66 to move until they are clamped onto both sides of the drone. The telescopic clamping rods 65, in conjunction with the compression springs 67, can effectively adjust the clamping force, thus facilitating proper fixation of the drone and preventing shaking during transportation, thereby avoiding damage to the drone.

[0025] Specifically, the inner wall of the storage and protection box 2 is provided with a sliding groove 21, and the two sides of the lifting platform 4 slide in the sliding groove 21 through guide sliders 42; the top of the storage and protection box 2 is connected to the box cover 23 by a hinge, and the two side walls of the storage and protection box 2 are provided with handles 22; the storage and protection box 2 is used to support the drone take-off and landing platform, and after use, it can store and protect the drone, and can also charge the drone through the power supply inside the storage and protection box 2.

[0026] Specifically, the bottom of the mobile carrier body 1 is equipped with movable rollers 11; the movable rollers 11 facilitate the movement of the device.

[0027] In addition, a power supply box for supplying power to the lead screw motor 72 and the second motor 62 is installed at the bottom of the storage and protection box 2.

[0028] Specifically, a level gauge is installed on the side wall of the takeoff platform 5.

[0029] The working principle and usage process of this utility model are as follows: When this utility model is used in actual surveying, the drone is transported to the area to be surveyed. The staff places the drone on the takeoff platform 5 and starts the second motor 62 to drive the bidirectional reciprocating screw 61 to rotate. The screw slider drives the clamping plate 64 to move in opposite directions, thereby driving the clamping block 66 to move until it is clamped on both sides of the drone body. The telescopic clamping rod 65, together with the compression spring 67, can be used to adjust the clamping force well, so as to facilitate the proper fixation of the drone and prevent shaking during transportation, thus avoiding damage to the drone.

[0030] After being transported to the testing area, the box cover 23 is flipped open, and the hydraulic lifting rod 3 is activated to drive the lifting platform 4 to rise along the inner wall groove 21 of the storage and protection box 2 via the guide slider 42 to the top opening of the storage and protection box 2. The lead screw motor 72 drives the lead screw 71 to rotate, which drives the adjusting arm 74 to move via the lead screw slide 73. During the movement of the adjusting arm 74, one end of the take-off platform 5 is supported and adjusted, so that the other end of the take-off platform 5 rotates on the lifting platform 4 via the pivot seat 41. With the help of the level gauge, the take-off platform 5 is leveled and adjusted to avoid the drone being unable to be placed flat on the take-off platform 5 due to uneven ground. This prevents the drone from failing to take off or landing or being prone to collisions due to the unevenness of the take-off platform 5.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
