Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to an anti-sinking type forest surveying unmanned aerial vehicle landing gear. Background Art

[0002] In forest survey work, drones have become an important tool for obtaining forest information due to their flexibility, convenience, efficiency and speed. Traditional forest survey drones can fly freely over land, and use survey cameras to clearly capture various conditions of forests, such as vegetation distribution, topography, etc., and transmit data back to the ground control center in real time through a data transmission system, providing strong support for subsequent forest planning, resource assessment and other work.

[0003] However, when faced with complex woodland environments, these drones expose many limitations. Woodlands often contain large amounts of water, such as streams, lakes, and swamps. Traditional drones lack effective water landing measures. Once they encounter emergencies during flight, such as low battery or mechanical failure, and need to make an emergency landing in the water, they are very likely to sink to the bottom of the water due to direct contact with the water surface, causing equipment damage. This not only results in the loss of expensive drone equipment, but may also lead to the loss of data that has not yet been transmitted, causing huge losses to the survey work.

[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 increase additional wind resistance during the normal flight of the drone, seriously affecting the flight stability and endurance. It may even make the drone unable to fly flexibly in the narrow space of the forest, and unable to meet the requirements of forest survey for drone maneuverability.

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

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an anti-sinking forest survey UAV landing gear. When in use, the operator only needs to easily start the UAV body through a remote control at the ground control center. After take-off, with the help of the high-definition survey camera carried in the UAV body, the forest can be clearly and comprehensively surveyed, 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 plate. At this time, the elastic mechanism plays a key role. Under the action of its strong elastic force, the float plate is quickly bounced up and rotates smoothly around the fixed axis. This process is cleverly designed. The float plate can accurately rotate to the notches at both ends of the landing gear, and then the machine is locked. The mechanism responds immediately and locks the float plate firmly in the notch position. After this series of coherent and precise operations, the flipped float plate remains perfectly parallel to the landing gear, and the float block also flips to the bottom of the float plate. In this way, when the drone body lands in the water, the float plate and the float block work together, and the landing gear floats steadily on the water surface with strong buoyancy. This not only effectively avoids the damage to the equipment caused by the drone sinking to the bottom of the water due to direct contact with the water surface, but also ensures that the data storage devices and various precision instruments in the body are 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 is properly restricted by the limiting mechanism above the landing gear and is in a compact storage state. This design fully considers the aerodynamic principles of the drone during flight and avoids the additional wind resistance caused by the deployment of the float, thereby ensuring that the drone can fly flexibly in the narrow space of the woods and maintain 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 guarantees for forest survey work.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-Figure 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 installed on the lower surface of the UAV body 101, and a landing gear 103 is fixedly installed on the end of the support rod 102, both ends of the landing gear 103 are tilted upward, 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, and an ear seat 104 is fixedly installed on the upper surface of the landing gear 103, and a fixed shaft 106 is fixedly installed 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 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 make the floating plate 105 bounce up and flip over to the notch 110 after the limiting mechanism releases the limiting of the floating plate 105; 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 is flipped over.

[0020] 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 floating plate 105 can be released through the limit mechanism. At this time, the floating plate 105 can be quickly bounced up and rotated around the fixed axis 106 under the elastic force of the elastic mechanism until the floating plate 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 floating plate 105 is locked. 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 limited above the landing gear 103 by the limiting mechanism, and is only unfolded to both sides when it is necessary to land in the water, which can avoid affecting the flight of the drone body 101 and achieve better use effect.

When the limiting mechanism releases the limit on the floating plate 105, the resetting effect of the first spring 204 can make the floating plate 105 quickly bounce up and flip over, and the use effect is better.

[0022] As an embodiment of the present invention, please refer to Figure 3 , Figure 4 and Figure 5 The locking mechanism includes a socket 302 opened on the inner wall of both sides of the notch 110, and a locking rod 301 is inserted in the socket 302, a mounting frame 305 is fixedly installed on the outer wall of the landing gear 103, and the locking rod 301 passes through the mounting frame 305, and one end of the locking rod 301 located in the notch 110 is provided with a first inclined surface 306, and the first inclined surface 306 is provided with an arc chamfer on one side facing the floating plate 105, so that the floating plate 105 can more easily push the locking rod 301 to move to both sides, and the other end of the locking rod 301 is fixedly installed with a fixing plate 303, and the fixing plate 303 and the mounting frame 305 are connected by a second spring 304, and a limiting block 307 is also fixedly installed on the outer wall of the locking rod 301, and the limiting block 307 is located between the mounting frame 305 and the fixing plate 303, and the lower part of the mounting frame 305 is also provided with a fixing plate 303.

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 under 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.

[0024] 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, a lifting plate 502 is fixedly installed on the telescopic end of the electric telescopic rod 501, a shaft 503 is fixedly installed on the side wall of the lifting plate 502, and a rotating plate 504 is rotatably sleeved on the outer side of the shaft 503, and pins 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 slide groove 506 is opened in the limiting plate 505, and the pin 507 is inserted in the slide groove 506, and the rotating plate 504 A limiting component is also provided to block the floating plate 105. When the limiting 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 laterally in the slide groove 506 until the limiting component in the rotating plate 504 is moved away from above the floating plate 105. Then, the limiting 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.

[0025] As an embodiment of the present invention, please refer to Figure 6 , Figure 7 and Figure 8The limiting assembly includes a telescopic plate 601, 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, and a baffle bar 1 602 and a baffle bar 2 603 are symmetrically installed on the outer wall of the telescopic plate 601, and the baffle bar 1 602 and the baffle bar 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 of the floating plate 105, the telescopic plate 601 can rotate with the rotating plate 504 until the telescopic plate 601 is moved away from the top of the floating plate 105, so that the limit of the floating plate 105 can be released, and when the flight is finished, the floating plate 105 needs to be limited again. When the lifting plate 502 is lowered, the lifting plate 502 can be driven downward by the electric telescopic rod 501 to reset the rotating plate 504 first, and then the telescopic plate 601 is pushed to make the baffle 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 turned over and pressed to make the floating plate 105 and the upper surface of the landing gear 103 fit closely. Then the telescopic plate 601 in the rotating plate 504 is pushed to move the telescopic plate 601 above the floating plate 105, and 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.

[0026] 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 provide a better use effect.

[0027] 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, which can effectively improve the stability during landing and provide a better use effect.

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. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
