Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) surveying technology, and in particular to a UAV landing platform for construction engineering surveying. Background Technology

[0002] Unmanned aerial vehicle (UAV) surveying further integrates and optimizes these technologies, using UAVs equipped with remote sensing sensors and other devices to acquire real-time geospatial information of target areas. It includes multiple stages such as remote sensing data processing, measurement and mapping, environmental modeling, and analysis, providing an efficient and convenient solution for surveying complex terrains.

[0003] Currently, in the actual process of drone surveying in construction projects, it is necessary to temporarily find or build a drone landing platform in the construction area to facilitate drone take-off and return operations during the survey. However, the current dedicated drone landing platforms are expensive, and directly using concrete or other hard platforms as the drone landing surface can easily lead to problems such as bumps and impact damage during the drone take-off and landing process.

[0004] In view of this, it is particularly important to design and manufacture a drone landing platform that is convenient for temporary on-site construction and can reduce the impact load during drone take-off and landing. Utility Model Content

[0005] The purpose of this utility model is to provide a UAV landing platform for construction engineering surveying in order to solve the above-mentioned technical defects in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A landing platform for unmanned aerial vehicles (UAVs) used for construction engineering surveying includes a landing platform consisting of two frames connected by hinges. A buffer section is provided between the upper ends of the two frames to reduce the impact load during the UAV's take-off and landing, and a ground support section is provided between the lower ends of the two frames to support the two frames at a certain height above the ground.

[0008] As a further description of the above technical solution:

[0009] The buffer section includes a lower groove formed at the upper ends of the two frames, hollow rubber blocks fixed at the four corners of the lower groove, a plastic plate fixed between the upper ends of the four hollow rubber blocks, and a spiral compression spring installed between the lower groove and the middle of the plastic plate.

[0010] As a further description of the above technical solution:

[0011] The upper surface of the plastic sheet is on the same horizontal plane as the upper surface of the frame.

[0012] As a further description of the above technical solution:

[0013] The ground support includes a rotating frame fixed at the four corners of the lower end of the two frames, a damping block rotatably installed inside the rotating frame, an outer threaded support column fixed on the damping block, and an inner threaded sleeve installed outside the outer threaded support column by threaded engagement.

[0014] As a further description of the above technical solution:

[0015] The front and sides of both frames are equipped with spirit levels.

[0016] As a further description of the above technical solution:

[0017] Handles are fixedly connected to the middle of the outer side of both frames.

[0018] As a further description of the above technical solution:

[0019] Both frames are made of aluminum alloy.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this invention, the drone landing platform consists of two frames, each equipped with a recessed groove, hollow rubber blocks, a spiral compression spring, a plastic plate, and foldable and adjustable support legs. In use, the two frames can be unfolded into a flat state, and the plastic plate can be adjusted to the upper part of the frames. When the drone lands on the top of the frames, the plastic plate disperses the impact load from the drone's takeoff and landing in multiple directions. The hollow rubber blocks located between the plastic plate and the four corners of the frames deform under pressure, thus flexibly absorbing and buffering the impact. Simultaneously, the spiral compression spring located between the plastic plate and the middle of the frames folds inward under pressure, further elastically buffering the impact load. This drone platform has a compact and portable structure, making it easy to temporarily set up in various terrains. It effectively reduces the impact load during drone takeoff and landing, minimizing the occurrence of bumps and impact damage, thereby improving the portability, applicability, and safety of the drone landing platform in actual surveying operations.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-3 This utility model provides a technical solution: a landing platform for unmanned aerial vehicles (UAVs) used for construction engineering surveying, including a landing platform. The landing platform is composed of two frames 1 connected by hinges. A buffer part is provided between the upper ends of the two frames 1 to reduce the impact load during the UAV's take-off and landing. A ground support part is provided between the lower ends of the two frames 1 to support the two frames 1 at a certain height above the ground.

[0029] Specifically, such as Figure 1-3 As shown, the buffer section includes a lower groove 101 opened on the upper end of the two frames 1, hollow rubber blocks 3 fixed at the four corners of the lower groove 101, a plastic plate 2 fixed between the upper ends of the four hollow rubber blocks 3, and a spiral compression spring 4 installed between the lower groove 101 and the middle of the plastic plate 2. The upper end surface of the plastic plate 2 is on the same horizontal plane as the upper end surface of the frame 1, ensuring that the upper end surface of the frame 1 is in a horizontal state under normal conditions, which does not affect the normal placement and adjustment of the drone.

[0030] Specifically, such as Figure 1-3As shown, the ground support includes a rotating frame 5 fixed at the four corners of the lower end of the two frame bodies 1, a damping block 501 rotatably installed inside the rotating frame 5, an outer threaded support column 6 fixed on the damping block 501, and an inner threaded sleeve 601 screwed onto the outside of the outer threaded support column 6. When the inner threaded sleeve 601 is rotated, it can move up or down on the outer threaded support column 6, thereby adjusting the overall ground clearance of the support leg structure, which facilitates the subsequent adjustment and ground support operation of the frame body 1. A spirit level 7 is installed at the front end and side of both frame bodies 1. By observing whether the bubble on the spirit level 7 is in the center, it can be determined whether the frame body 1 is in a level state, which facilitates the leveling operation after the frame body 1 is adjusted.

[0031] Specifically, such as Figure 1-3 As shown, handles 102 are fixedly connected to the middle of the outer side of both frames 1. After the two frames 1 are folded, the handles 102 on the two frames 1 can be combined together, which makes it convenient for operators to pick up, put down and move the frames 1. Both frames 1 are made of aluminum alloy, which makes the overall weight of the UAV landing platform lighter and the overall structural strength better.

[0032] Working principle: When setting up a drone landing platform, unfold the two frame bodies 1 to a flat state, with the plastic plate 2 facing upwards. Rotate the outer threaded support columns 6 at the four corners of frame body 1 outwards on the rotating frame 5 via damping rotating blocks 501. Once all four inner threaded sleeves 601 are in contact with the ground, observe whether frame body 1 is level using the spirit level 7 at different positions. If it is tilted, adjust the inner threaded sleeves 601 on the outer threaded support columns 6 at the designated positions until they are stably in contact with the ground. At this point, the drone landing platform setup is complete, and the drone can be placed between the two frame bodies 1 for subsequent drone surveying operations. During the takeoff and landing of the drone, the drone support can make contact with the plastic plate 2 in advance. The plastic plate 2 can disperse the local impact force. The spiral compression spring 4 located between the plastic plate 2 and the frame 1 will fold inward and deform when subjected to impact load, thus performing the first step of elastic deformation buffering treatment of the impact load. When the impact load is dispersed outward to the four corners of the plastic plate 2, the hollow rubber block 3 located between the four corners of the plastic plate 2 and the frame 1 can be squeezed downward and deformed when subjected to force, thereby flexibly absorbing and buffering the impact force, thus comprehensively reducing the impact load during the takeoff and landing of the drone and reducing the rigid impact damage during the takeoff and landing of the drone.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
