Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to an anti-sinking type landing gear for a forest survey UAV. Background Art

[0002] In forest surveys, drones, with their flexibility, convenience, efficiency, and speed, have become a crucial tool for obtaining forest information. Traditional forest survey drones can fly freely over land, using survey cameras to clearly capture various forest conditions, such as vegetation distribution and topography. These data are then transmitted back to ground control centers in real time via data transmission systems, providing strong support for subsequent forest planning and resource assessments.

[0003] However, these drones expose numerous limitations when operating in complex woodland environments. Woodlands often contain large bodies of water, such as streams, lakes, and swamps. Traditional drones lack effective water landing systems. If an emergency occurs during flight, such as a low battery or mechanical failure, requiring an emergency landing in water, they are prone to sinking due to direct contact with the water surface, causing damage to the equipment. This not only results in the loss of expensive drone equipment but also potentially untransmitted data, resulting in significant losses for survey operations.

[0004] At the same time, if the drone is equipped with floating devices such as large floats that are always deployed in order to cope with possible water landing scenarios, it will add additional wind resistance during the normal flight of the drone, seriously affecting the flight stability and endurance. It may even cause the drone to be unable to fly flexibly in the narrow space of the forest, and fail to meet the requirements of forest surveys for drone maneuverability.

[0005] Therefore, developing an unmanned aerial vehicle device that can not only maintain its performance during normal flight but also quickly deploy an effective floating structure when landing in water, thereby improving its adaptability and safety in complex forest environments, has become a key issue that needs to be urgently addressed in the current field of forest surveying.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention provides an anti-sinking forest survey UAV landing gear. When in use, the operator only needs to start the UAV body easily through the remote control at the ground control center. After takeoff, with the help of the high-definition survey camera installed in the UAV body, the forest can be explored clearly and comprehensively, providing rich and accurate data for subsequent forest research and management. When the UAV faces a complex forest environment, especially when it needs to land in water, its unique design shows its advantages; through the limit mechanism, the operator only needs to perform simple operations to quickly release the limit on the float. At this time, the elastic mechanism plays a key role. Under the action of its strong elastic force, the float is quickly bounced up and rotates smoothly around the fixed axis. This process is cleverly designed. The float can be accurately rotated to the notch at both ends of the landing gear, and then the machine is locked. The mechanism responded immediately and locked the float firmly in the notch position. After this series of coherent and precise operations, the flipped float remained perfectly parallel to the landing gear, and the float block also flipped to the bottom of the float. In this way, when the drone body landed in the water, the float plate and the float block worked together, and with their strong buoyancy, the landing gear floated steadily on the water surface. This not only effectively avoided the equipment damage caused by the drone sinking to the bottom due to direct contact with the water surface, but also ensured that the data storage equipment and various precision instruments in the body were not affected by water immersion, ensuring the integrity of the data and the repairability of the equipment, greatly improving the adaptability and safety of the drone in complex woodland environments. Furthermore, during the normal flight phase of the drone, the float plate was properly restricted by the limiting mechanism above the landing gear and was in a compact storage state. This design fully considers the aerodynamic principles of drone flight, avoiding the additional wind resistance caused by the deployment of the float, thereby ensuring that the drone body can fly flexibly in the narrow space of the woods, maintaining good flight stability and long endurance. Whether it is passing through the gaps between dense woods or maintaining a stable flight posture in strong winds, it can easily cope with it, providing efficient and reliable flight support for forest survey work.

DETAILED DESCRIPTION

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1-10As shown, an anti-sinking forest survey UAV landing gear provided by an embodiment of the present invention includes an UAV body 101, a support rod 102 is fixedly mounted on the lower surface of the UAV body 101, and a landing gear 103 is fixedly mounted on the end of the support rod 102, both ends of the landing gear 103 are upwardly tilted, and a notch 110 is opened at the tilted end of the landing gear 103, and a floating plate 105 is symmetrically arranged on the upper surface of the landing gear 103. Ear seats 104 are fixedly mounted on the upper surface of the landing gear 103, and a fixed shaft 106 is fixedly mounted between adjacent ear seats 104, and the floating plate 105 is rotatably sleeved on the outer side of the fixed shaft 106. A floating block 109 is also fixedly installed on the upper surface of the floating plate 105, and a groove is also opened on the side wall of the unmanned aerial vehicle body 101, and a survey camera 111 is fixedly installed in the groove. It also includes: a limiting mechanism, which is arranged on the upper surface of the landing gear 103, and is used to limit the position of the floating plate 105; an elastic mechanism, which is arranged on both sides of the landing gear 103, and is used to release the limiting mechanism on the floating plate 105, so that the floating plate 105 bounces up and flips into the notch 110; a locking mechanism, which is arranged at the raised end of the landing gear 103, and is used to limit the floating plate 105 in the notch 110 after the floating plate 105 flips over.

[0034] During use, the operator starts the drone body 101 through the remote control of the ground control center. After the drone body 101 takes off, it can use the survey camera 111 in the drone body 101 to conduct exploration. The data transmission system will transmit the data obtained by the survey camera 111 back to the ground control center in real time. When the drone needs to land in the water, the limit of the float 105 can be released through the limit mechanism. At this time, the float 105 can be quickly bounced up and rotated around the fixed axis 106 under the elastic force of the elastic mechanism until the float 105 rotates to the notch 110 at both ends of the landing gear 103. At this time, under the locking action of the locking mechanism, The float 105 can be locked in the notch 110 so that the flipped float 105 remains parallel to the landing gear 103, and the float block 109 is also flipped to the bottom of the float 105. When the drone body 101 lands in the water, the landing gear 103 can float on the water with the help of the float 105 and the float block 109, which effectively improves the adaptability and safety of the drone in complex forest environments. When the drone body 101 is flying normally, the float 105 is restricted above the landing gear 103 by the limiting mechanism, and is only unfolded to both sides when it needs to land in the water, which can avoid affecting the flight of the drone body 101 and has a better use effect.

[0035] As an embodiment of the present invention, please refer to Figure 6The elastic mechanism includes a bracket 201 fixedly arranged on the upper surface of the landing gear 103. The upper surface of the bracket 201 is provided with a mounting hole, and a spring rod 202 is movably installed in the mounting hole. A baffle 203 is fixedly installed on the top of the spring rod 202. The bottom end of the spring rod 202 is in contact with the upper surface of the landing gear 103. A first spring 204 is sleeved on the outer side of the spring rod 202. One end of the first spring 204 is connected to the baffle 203, and the other end of the first spring 204 is connected to the upper surface of the bracket 201. When the limiting mechanism releases the limit on the floating plate 105, the resetting action of the first spring 204 can make the floating plate 105 quickly bounce up and flip over, and the use effect is better.

[0036] As an embodiment of the present invention, please refer to Figure 3 、 Figure 4 and Figure 5 When the lock 310 is unlocked, the lock 310 is unlocked, and the lock 310 is unlocked, and the lock 310 is unlocked. The lock 310 is unlocked, and the lock 310 is unlocked. When the locking lever 301 is unlocked, the first bevel 306 at the end of the locking lever 301 is in contact with the second bevel 306 at the end of the locking lever 301. When the locking lever 301 is unlocked, the first bevel 306 at the end of the locking lever 301 is in contact with the first bevel 306 at the end of the locking lever 301. When the locking lever 301 is unlocked, the first bevel 306 at the end of the locking lever 301 is in contact with the first bevel 306 at the end of the locking lever 301. When the locking lever 301 is unlocked, the first bevel 306 at the end of the locking lever 301 is in contact with the first bevel 306 at the end of the locking lever 301. When the locking lever 301 is unlocked, the first bevel 306 at the end of the locking lever 301 is in contact with the first bevel 306 at the end of the locking lever 301. When the locking lever 301 is unlocked, the first bevel 306 at the end of the locking lever 301 is in contact with the first bevel 306 at the end of the locking lever 301. When the locking lever 301 is unlocked, the first bevel 306 at the end of the locking lever 301 is in contact with the first bevel 306 at the end of the locking lever

[0037] As an embodiment of the present invention, please refer to Figure 3 、 Figure 4 and Figure 5The unlocking assembly includes a mounting groove 401 provided at the bottom end of the landing gear 103, a vertical rod 402 is fixedly installed on the top inner wall of the mounting groove 401, and a stopper 403 is fixedly installed on the bottom end of the vertical rod 402, a trigger member 404 is sleeved on the outer side of the vertical rod 402, and the cross section of the trigger member 404 is U-shaped, the top end of the trigger member 404 passes through the mounting frame 305, and the top end of the trigger member 404 is provided with a second inclined surface 405, and the lower surface of the locking rod 301 is provided with a second inclined surface 405. The two inclined surfaces 405 cooperate with the inclined groove 406. When the flight is over and the floating plate 105 needs to be reset, the trigger member 404 on the outside of the vertical rod 402 can be directly pushed upward, so that the second inclined surface 405 at the top of the trigger member 404 is inserted into the inclined groove 406 below the locking rod 301, which can drive the locking rod 301 to move toward the fixed plate 303, so that the locking position of the floating plate 105 can be quickly released, and then the floating plate 105 can be flipped over again, which is very convenient to use.

[0038] As an embodiment of the present invention, please refer to Figure 6 、 Figure 7 and Figure 8 The limiting mechanism includes an electric telescopic rod 501 fixedly arranged on the upper surface of the landing gear 103, and a lifting plate 502 is fixedly installed on the telescopic end of the electric telescopic rod 501. The side wall of the lifting plate 502 is fixedly installed with a shaft rod 503, and a rotating plate 504 is rotatably sleeved on the outer side of the shaft rod 503. Pin rods 507 are also fixedly installed on the outer walls of the rotating plate 504. A limiting plate 505 is fixedly installed on the upper surface of the landing gear 103, and a sliding groove 506 is opened in the limiting plate 505. The pin rod 507 is inserted into the sliding groove 506, and the rotating plate 504 is fixedly installed. A limiting component is also provided in the middle to block the floating plate 105. When the limit of the floating plate 105 needs to be released, the lifting plate 502 can be driven upward by the electric telescopic rod 501, and the shaft rod 503 on one side of the lifting plate 502 will drive the rotating plate 504 to rotate, so that the pin rod 507 on the side wall of the rotating plate 504 moves horizontally in the slide groove 506 until the limiting component in the rotating plate 504 is removed from above the floating plate 105. Then, the limit of the floating plate 105 can be released, so that the floating plate 105 is quickly bounced up by the elastic structure, and the use effect is better.

[0039] As an embodiment of the present invention, please refer to Figure 6 、 Figure 7 and Figure 8The limiting component includes a telescopic plate 601, and a telescopic opening is provided on the outer wall of the rotating plate 504, and the telescopic plate 601 is movably installed in the telescopic opening. The outer wall of the telescopic plate 601 is symmetrically installed with a baffle 1 602 and a baffle 2 603, and the baffle 1 602 and the baffle 2 603 are respectively located on both sides of the rotating plate 504. When limiting, the telescopic plate 601 in the rotating plate 504 is mainly used to block the floating plate 105 to achieve the purpose of limiting. When it is necessary to release the limit on the floating plate 105, the telescopic plate 601 can rotate with the rotating plate 504 until the telescopic plate 601 is moved from above the floating plate 105 to release the limit on the floating plate 105. When the flight is over, the floating plate 105 needs to be limited again. When the lifting plate 502 is lowered, the electric telescopic rod 501 can be used to drive the lifting plate 502 to move downward, so that the rotating plate 504 is reset first, and then the telescopic plate 601 is pushed to make the blocking bar 602 on the outer wall of the telescopic plate 601 fit with the side wall of the rotating plate 504. At this time, the floating plate 105 can be flipped and pressed to make the floating plate 105 fit tightly with the upper surface of the landing gear 103, and then the telescopic plate 601 in the rotating plate 504 is pushed to move the telescopic plate 601 above the floating plate 105, so that the floating plate 105 can be re-limited. This re-limiting method only requires one person to complete the resetting operation of all floating plates 105, and the operation is simple, and the use effect is better.

[0040] As an embodiment of the present invention, please refer to Figure 5 A through opening 107 is also provided on the lower surface of the landing gear 103, and the length of the through opening 107 is less than the length of the floating plate 105. By providing the through opening 107 under the landing gear 103, the weight of the landing gear 103 can be effectively reduced, making the overall weight of the UAV device lighter, which can indirectly extend the flight time of the UAV body 101 and achieve better use effect.

[0041] As an embodiment of the present invention, please refer to Figure 5 The lower surface of the landing gear 103 is also fixedly mounted with an anti-skid pad 108. The anti-skid pad 108 can prevent the UAV device from slipping when landing on a slope, effectively improving the stability during landing and achieving better use effect.

[0042] It should be noted that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
