Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology for geographic remote sensing and mapping, and in particular to a UAV flight platform for geographic remote sensing and mapping. Background Technology

[0002] A geographic remote sensing and mapping drone flight platform is a drone system specifically designed to carry remote sensing sensors and quickly acquire information about ground targets through remote control or autonomous flight.

[0003] According to the Chinese patent "A Geographic Mapping Unmanned Aerial Vehicle" authorized announcement number "CN219821769U", the air pump, airbag and shell can protect the mapping camera at the bottom of the drone body when the drone body falls accidentally. This effectively avoids the drawback of the mapping camera being damaged when the drone body falls accidentally, which is very likely to lead to the loss of mapping data.

[0004] In the aforementioned application, because the bottom of the surveying camera is not protected, when the main body of the drone falls accidentally, small pebbles or branches can easily collide with the bottom of the surveying camera, causing damage to the surveying camera and thus reducing the protective effect on the surveying camera.

[0005] Therefore, a UAV flight platform for geographic remote sensing mapping is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a drone flight platform for geographic remote sensing mapping in order to solve the above-mentioned problems, thereby improving the problem that small stones or branches can easily collide with the bottom of the mapping camera and cause damage to the mapping camera.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: a UAV flight platform for geographic remote sensing mapping, comprising: a UAV; and a protective mechanism, the protective mechanism including a transparent rubber frame fixedly connected to the end of the UAV, a transparent plate snapped onto the front end of the transparent rubber frame, corrugated rubber pads fixedly connected to the front end of the transparent plate and the bottom of the transparent rubber frame, a transparent rubber block fixedly connected to one end of the corrugated rubber pad, and a visible light camera hinged to the upper end of the inner wall of the transparent rubber frame. Through the transparent rubber frame and transparent plate, the visible light camera is fully protected, thus preventing small stones or branches from colliding with the surface of the mapping camera, thereby avoiding the risk of data loss due to damage to the visible light camera. The corrugated rubber pad and transparent rubber plate cushion the impact to the bottom of the transparent rubber frame and the front end of the transparent plate, preventing damage to the surfaces of the transparent rubber frame and transparent plate, and ensuring the protective effect on the visible light camera.

[0008] Preferably, a bracket is slidably connected to the inner wall of the transparent rubber frame, the surface of the bracket is snapped into the inner wall of the transparent plate, and a spring is fixedly connected to the opposite end of the bracket and the transparent rubber frame.

[0009] Preferably, a fixing plate is slidably connected to the upper end of the inner wall of the transparent rubber frame. The spring and the clip lock the transparent plate onto the transparent rubber frame, while the fixing plate restricts the upward movement of the clip, ensuring the stable installation of the transparent plate on the transparent rubber frame and thus guaranteeing the protective effect on the visible light camera.

[0010] Preferably, a mounting block is fixedly connected to one side of the transparent rubber frame, and one side of the fixing plate contacts one side of the mounting block.

[0011] Preferably, a limiting rod is slidably connected to the upper end of the inner wall of the transparent rubber frame, and the surface of the limiting rod is slidably connected to the inner wall of the fixing plate. The placement block limits the sliding of the fixing plate into the transparent rubber frame, thereby allowing the limiting rod to slide precisely into the fixing plate, thus achieving the limitation of the fixing plate.

[0012] Preferably, a limiting groove is provided at the upper end of the inner wall of the transparent rubber frame, and the end of the limiting rod is engaged with the inner wall of the limiting groove.

[0013] Preferably, an elastic sleeve is fixedly connected to the opposite end of the card holder and the transparent rubber frame, and the surface of the spring is located inside the elastic sleeve. The elastic sleeve protects the spring and prevents impurities from adhering to the spring surface.

[0014] The beneficial effects of this utility model are:

[0015] 1. By using a transparent rubber frame and a transparent plate, the visible light camera is fully protected. The corrugated rubber pad and the transparent rubber plate cushion the bottom of the transparent rubber frame and the front of the transparent plate in case of impact, preventing damage to the surface of the transparent rubber frame and the transparent plate. Compared with existing methods where small pebbles or branches can easily collide with the surface of the surveying camera, this method provides comprehensive protection for the visible light camera, thereby avoiding the risk of loss of surveying data due to damage to the visible light camera, and thus ensuring the protective effect of the visible light camera.

[0016] 2. The spring and the clip lock the transparent plate onto the transparent rubber frame. The fixing plate restricts the upward movement of the clip, ensuring the transparent plate is stably installed on the transparent rubber frame, thus guaranteeing the protection of the visible light camera.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, a UAV flight platform for geographic remote sensing mapping includes: a UAV 1; and a protective mechanism 2. The protective mechanism 2 includes a transparent rubber frame 21 fixedly connected to the end of the UAV 1. A transparent plate 22 is snapped onto the front end of the transparent rubber frame 21. Corrugated rubber pads 23 are fixedly connected to both the front end of the transparent plate 22 and the bottom of the transparent rubber frame 21. A rubber transparent block 24 is fixedly connected to one end of the corrugated rubber pad 23. A visible light camera 25 is hinged to the upper end of the inner wall of the transparent rubber frame 21. The glass on the surfaces of the transparent rubber frame 21, the transparent plate 22, and the rubber transparent block 24 are all tempered glass components.

[0024] A drone typically includes components such as a fuselage, wings, landing gear, and a power system such as a motor and propeller.

[0025] The end of the UAV 1 is fixedly connected to a lidar, a distance sensor, and a leg. The bottom of the leg is fixedly connected to a buffer airbag, and the top of the leg is fixedly connected to a miniature air pump. The air supply end of the miniature air pump passes through the leg and connects to the inside of the buffer airbag. The upper end of the inner wall of the transparent rubber frame 21 is fixedly connected to a servo motor, and the output shaft of the servo motor is fixedly connected to one end of the visible light camera 25.

[0026] Servo motors are used to control the shooting angle of visible light camera 25. Servo motors can control speed and have very accurate position. They can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In automatic control systems, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signals into angular displacement or angular velocity output on the motor shaft.

[0027] Before use, the micro air pump of the drone 1 is manually turned on. The micro air pump draws in outside air and inputs it into the buffer airbag, causing the buffer airbag to expand to a suitable range. In the event of an accidental crash, the buffer airbag can protect the transparent rubber frame 21 at the bottom of the drone 1. Small pebbles or branches will collide with the transparent rubber block 24. The impact of the transparent rubber block 24 will compress the corrugated rubber pad 23. Because rubber has good elasticity, when the corrugated rubber pad 23 is impacted by external force, the rubber molecular chains will deform, converting mechanical energy into elastic potential energy and storing it, thereby mitigating the impact force on the transparent rubber block 24.

[0028] When remote sensing mapping of mountainous areas is required, a visible light camera 25 is installed inside a transparent rubber frame 21, and a transparent plate 22 is inserted and installed onto the transparent rubber frame 21. The transparent rubber frame 21 is then installed at the end of the UAV 1 using bolts. At this time, the UAV 1, visible light camera 25, lidar, and distance sensor are activated via the control handle, thereby controlling the UAV 1 to fly into the air. The visible light camera 25 is used to capture images of the mountainous ground, generating orthophotos and 3D models. The lidar can penetrate obstacles such as vegetation and clouds to obtain high-precision terrain data. The collected data is then transmitted to the ground control station in real time via wireless communication technology. The ground control station uses geographic information system technology to perform spatial analysis on the mapping data, calculate parameters such as terrain, landforms, and vegetation coverage of the survey area, and thus obtain geographic remote sensing data.

[0029] like Figure 2 As shown, a bracket 26 is slidably connected to the inner wall of the transparent rubber frame 21. The surface of the bracket 26 is snapped onto the inner wall of the transparent plate 22. A spring 27 is fixedly connected to the opposite end of the bracket 26 and the transparent rubber frame 21. An elastic sleeve 212 is fixedly connected to the opposite end of the bracket 26 and the transparent rubber frame 21. The surface of the spring 27 is located inside the elastic sleeve 212. The elastic sleeve 212 is a silicone component.

[0030] The elastic force of the spring 27 pushes the card holder 26 down and engages with the transparent plate 22, so that the transparent plate 22 is mounted on the transparent rubber frame 21.

[0031] like Figure 4As shown, a fixing plate 28 is slidably connected to the upper end of the inner wall of the transparent rubber frame 21, and a placement block 29 is fixedly connected to one side of the transparent rubber frame 21. One side of the fixing plate 28 contacts one side of the placement block 29. A limiting rod 210 is slidably connected to the upper end of the inner wall of the transparent rubber frame 21. The surface of the limiting rod 210 is slidably connected to the inner wall of the fixing plate 28. A limiting groove 211 is opened at the upper end of the inner wall of the transparent rubber frame 21, and the end of the limiting rod 210 is engaged with the inner wall of the limiting groove 211.

[0032] Insert the fixing plate 28 into the transparent rubber frame 21, so that one side of the fixing plate 28 abuts against the mounting block 29, the bottom of the fixing plate 28 abuts against the top of the bracket 26, and the top of the fixing plate 28 abuts against the inner top wall of the transparent rubber frame 21. Push the limiting rod 210 so that the limiting rod 210 moves within the transparent rubber frame 21 and slides into the fixing plate 28 and the limiting groove 211. At this time, rotate the limiting rod 210 so that the protruding end of the limiting rod 210 abuts against the upper end of the inner wall of the limiting groove 211.

[0033] In use, the visible light camera 25 is installed inside the transparent rubber frame 21, and the transparent plate 22 is inserted into the transparent rubber frame 21. The bracket 26 is loosened, and the elastic force of the spring 27 pushes the bracket 26 down to engage with the transparent plate 22, so that the transparent plate 22 is installed on the transparent rubber frame 21. The fixing plate 28 is inserted into the transparent rubber frame 21, so that one side of the fixing plate 28 abuts against the mounting block 29, the bottom of the fixing plate 28 abuts against the top of the bracket 26, and the top of the fixing plate 28 abuts against the inner top wall of the transparent rubber frame 21. The limiting rod 210 is pushed, so that the limiting rod 210 moves inside the transparent rubber frame 21 and slides into the fixing plate 28 and the limiting groove 211. At this time, the limiting rod 210 is rotated, so that the protruding end of the limiting rod 210 abuts against the upper end of the inner wall of the limiting groove 211, so that the fixing plate 28 is stably positioned inside the transparent rubber frame 21. The transparent rubber frame 21 is then installed at the end of the drone 1 by bolts.

[0034] It should be noted that the drone 1, visible light camera 25, outriggers, airbags, miniature air pump, servo motor, lidar, and distance sensor mentioned above are all components with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the drone 1, visible light camera 25, miniature air pump, servo motor, lidar, and distance sensor can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
