Description

Technical Field

[0001] The present invention belongs to the technical field related to drone nests, and more specifically, particularly relates to a vertical take-off and landing fixed-wing drone nest. Background Art

[0002] A drone is an unmanned aircraft that is mainly operated by a radio remote control device or a self-contained program control device. Some drones also have the ability to be fully or intermittently controlled autonomously by an onboard computer. In recent years, drone technology has developed rapidly, and its application areas have continued to expand. It has been widely used in many industries such as aerial photography, agricultural plant protection, surveying and mapping, news reporting, power inspection, disaster relief, and film and television shooting. However, with the increasing demand for the use of drones, their management and maintenance in non-working states have become particularly important. In order to ensure the safety and performance of drones, drones usually need to return to specially designed nests when not in use for protection and charging, thereby extending their service life and ensuring the smooth execution of the next mission.

[0003] The prior art is a patent document with publication number CN202110771646.X. The patent discloses that the key points of its technical solution are: the machine nest can realize automatic retraction and release, automatic charging, unattended operation, data upload, remote real-time monitoring, automatic mode can be released, manual remote operation can be performed, and it is compatible with vertical take-off and landing drones and multi-rotor drones. However, the prior art of a vertical take-off and landing fixed-wing drone automatic recovery charging machine nest still has the following defects:

[0004] 1. In the prior art, when a drone is working outdoors for a long time, a large amount of dust will be attached to it due to its own static electricity. The long-term accumulation of this dust will affect the drone and the nest, thereby affecting the service life of the drone and the nest, and even seriously damaging the drone and the nest;

[0005] 2. In the prior art, the top cover of the machine nest is flat, while the sides are sloped. In daily use, the machine nest is usually in an outdoor environment and is outdoors for a long time. This design will cause water leakage for a long time, which will cause damage to the equipment and the drone.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a vertical take-off and landing fixed-wing UAV nest is provided, in order to achieve a more practical purpose. Summary of the invention

[0007] The present invention provides a vertical take-off and landing fixed-wing UAV machine nest, which is used to overcome the above-mentioned defects in the prior art.

[0008] The purpose and effect of the vertical take-off and landing fixed-wing UAV nest of the present invention are achieved by the following specific technical means:

[0009] A vertical takeoff and landing fixed-wing UAV nest, comprising a nest housing. Fixed frames are welded and installed on both side surfaces of the nest housing. A protection unit is arranged on the outer surface of the nest housing and the fixed frames. A fixing unit is arranged on the outer surface of the protection unit. A cleaning unit is arranged on the outer surface of the nest housing and the protection unit.

[0010] The protection unit includes an arc cover plate one and an arc cover plate two. The arc cover plate one and the arc cover plate two are respectively rotatably connected to the inner surface of the nest housing through a rotating shaft one and a rotating shaft two. Arc-shaped rods one and two are respectively welded and installed on the outer surfaces of the arc cover plate one and the arc cover plate two. Moon-shaped gears one and two are respectively welded and installed on the outer surfaces of the arc-shaped rods one and two. An electric screw rod is fixedly installed on the inner surface of the nest housing. A double-sided panel tooth is threadedly installed at the working end of the electric screw rod. The other end of the arc cover plate one is welded and installed with a flat plate. A parking plate is fixedly installed above the upper edge of the flat plate. The moon-shaped gears one and two are meshed with the double-sided panel tooth.

[0011] A further technical solution, the cleaning unit includes nozzles. Straight pipes are fixedly installed in the symmetrically opened grooves on the upper surface of the flat plate. A plurality of nozzles are installed on the outer surfaces of the two straight pipes. Compression bottles are installed on both side surfaces inside the nest housing. The air outlet holes of the compression bottles are connected to the air inlet holes of the straight pipes through spring pipes.

[0012] A further technical solution, air pumps are installed on both side surfaces inside the nest housing. The air outlet holes of the air pumps are connected to the air inlet holes of the compression bottles through hoses. A shaft rod and a linkage piece are rotatably installed on the inner surface of the nest housing. Circular gears are installed on the outer surfaces of the shaft rods. A push rod is rotatably installed on the outer surface of the linkage piece. The outer surface of the push rod is rotatably connected to the air rod of the air pump.

[0013] A further technical solution, the double-sided panel tooth is meshed with the circular gear. One end of the shaft rod is rotatably installed on one side surface inside the nest housing, and the other end of the shaft rod is rotatably installed on the other side surface of the nest housing through the linkage piece.

[0014] A further technical solution, an infrared sensing piece is installed on the outer surface of the parking plate. A positioning block is welded and installed on the outer surface of the air pump. The air rod of the air pump is slidably connected to the inner surface of the positioning block.

[0015] Further technical solution: The fixing unit includes a top plate and a vertical fixed-wing UAV. Rotating pieces are welded and installed on the inner surfaces of the first arc-shaped cover plate and the second arc-shaped cover plate. The top plate is rotatably installed on the outer surface of the rotating piece. Slide bars are installed in the symmetrically arranged grooves on the upper surface of the parking plate. Springs are sleeved on the outer surfaces of the slide bars, and sliding blocks are slidably installed on the outer surfaces of the slide bars.

[0016] Further technical solution: A pin shaft is welded and installed on the outer surface of the sliding block, and a pin block is installed on the lower surface of the vertical fixed-wing UAV. The pin block is snap-fitted on the pin shaft.

[0017] Further technical solution: The top plate and the sliding block are magnetically connected, the pin block and the infrared sensing piece are magnetically connected, and a top piece is welded and installed on the outer surface of the rotating piece.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] For the vertical takeoff and landing fixed-wing UAV nest of the present invention, when the double-sided panel teeth move upward in the cleaning unit, the double-sided panel teeth will drive the circular gear to rotate, thereby driving the shaft rod to rotate. Then the shaft rod drives the linkage piece to rotate, so that the push rod pulls the pull rod of the air pump, starts the air pump and inflates the compression bottle through the hose. When the vertical fixed-wing UAV descends, the pin block magnetically adheres to the infrared sensing piece to achieve the effect of positioning and landing. The infrared sensing piece senses the magnetically attracted pin block. At this time, the compression bottle is started to inflate the straight pipe through the spring pipe, and the high-pressure gas is sprayed out dispersedly by the nozzle, so as to spray off the dust carried by the vertical fixed-wing UAV.

[0020] For the vertical takeoff and landing fixed-wing UAV nest of the present invention, when the electric screw rod in the protection unit works to drive the double-sided panel teeth to move upward, the first moon gear and the second moon gear engaged with the double-sided panel teeth perform circular arc movements at this time, so that the first arc rod and the second arc rod drive the first arc-shaped cover plate and the second arc-shaped cover plate to rotate outward respectively around the first rotating shaft and the second rotating shaft, so as to unfold the first arc-shaped cover plate and the second arc-shaped cover plate. At the same time when the double-sided panel teeth move upward, the flat plate and the parking plate will be driven to move upward.

[0021] For the vertical takeoff and landing fixed-wing UAV nest of the present invention, when the electric screw rod in the fixing unit works in the reverse direction, the first moon gear and the second moon gear engaged with the double-sided panel teeth perform circular arc movements again, so that the first arc rod and the second arc rod drive the first arc-shaped cover plate and the second arc-shaped cover plate to rotate outward respectively around the first rotating shaft and the second rotating shaft, so as to close the first arc-shaped cover plate and the second arc-shaped cover plate. When closing, the top plate rotatably installed on the rotating piece pushes the sliding block to compress the spring and slide on the slide rod, so that the pin shaft is snap-fitted on the pin block, and the vertical fixed-wing UAV is fixed.

In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] As shown in the attached Figure 1 to the attached Figure 8 figures: The present invention provides a vertical takeoff and landing fixed-wing UAV nest, which includes a nest housing 1. Fixed frames 2 are welded and installed on both side surfaces of the nest housing 1. A protection unit 3 is arranged on the outer surface of the nest housing 1 and the fixed frames 2. A fixing unit 4 is arranged on the outer surface of the protection unit 3. A cleaning unit 5 is arranged on the outer surface of the nest housing 1 and the protection unit 3;

[0036] The protection unit 3 includes an arc cover plate one 301 and an arc cover plate two 302. The arc cover plate one 301 and the arc cover plate two 302 are respectively rotatably connected to the inner surface of the nest housing 1 through a rotating shaft one 303 and a rotating shaft two 304. Arc-shaped rods one 305 and arc-shaped rods two 306 are respectively welded and installed on the outer surfaces of the arc cover plate one 301 and the arc cover plate two 302. Moon-shaped gears one 307 and moon-shaped gears two 308 are respectively welded and installed on the outer surfaces of the arc-shaped rods one 305 and the arc-shaped rods two 306. An electric screw rod 309 is fixedly installed on the inner surface of the nest housing 1. A double-sided plate gear 310 is threadedly installed at the working end of the electric screw rod 309. The other end of the arc cover plate one 301 is welded and installed with a flat plate 311. A parking plate 312 is fixedly installed on the upper edge of the flat plate 311. The moon-shaped gears one 307, the moon-shaped gears two 308 are meshed with the double-sided plate gear 310.

[0037] In this embodiment, when the arc cover plate 1-301 and the arc cover plate 2-302 rotate around the rotation shaft 1-303 and the rotation shaft 2-304, they are tangent to the inner surface of the nacelle housing 1. The arc cover plate 1-301 and the arc cover plate 2-302 can form a closed chamber when closed. The rotation angles of the arc-shaped rod 1-305 and the arc-shaped rod 2-306 are in a 2:1 relationship with the rotation angles of the arc cover plate 1-301 and the arc cover plate 2-302. Thus, when rotating around the rotation shaft 1-303, when the moon gear 1-307 rotates circumferentially, the moon gear 1-307 always meshes with the double-sided panel teeth 310, and the lengths of the vertical positions from the axis of the rotation shaft 1-303 to any point on the 307 are the same. The connection between the double-sided panel teeth 310 and the flat plate 311 has a connecting plate to make the 311 stable. While the arc cover plate 1-301 and the arc cover plate 2-302 drive the arc cover plate 1-301 and the arc cover plate 2-302 to work, it also ensures that when the electric screw rod 309 drives the double-sided panel teeth 310 to move, the double-sided panel teeth 310 will not rotate.

[0038] Preferably, the cleaning unit 5 includes a nozzle 510. Straight pipes 509 are fixedly installed in the symmetrically opened grooves on the upper surface of the flat plate 311. A plurality of nozzles 510 are installed on the outer surfaces of the two straight pipes 509. Compression bottles 507 are installed on both side surfaces inside the nacelle housing 1. The air outlet holes of the compression bottles 507 are connected to the air inlet holes of the straight pipes 509 through spring pipes 511.

[0039] In this embodiment, the switch of the compression bottle 507 is determined by whether the pin block 408 is magnetically attracted to the 512. When the pin block 408 is magnetically attracted to the 512, the compression bottle 507 opens to work. Conversely, it closes. And when the pin block 408 is magnetically attracted to the 512, the compression bottle 507 causes the electric screw rod 309 to reverse, and the spring pipe 511 ensures the normal movement of the flat plate 311.

[0040] Preferably, air pumps 505 are installed on both side surfaces inside the nacelle housing 1. The air outlet holes of the air pumps 505 are connected to the air inlet holes of the compression bottles 507 through hoses 508. Shaft rods 501 and linkage pieces 503 are rotatably installed on the inner side surface of the nacelle housing 1. Circular gears 502 are installed on the outer surfaces of the shaft rods 501. Push rods 504 are rotatably installed on the outer surfaces of the linkage pieces 503. The outer surfaces of the push rods 504 are rotatably connected to the air rods of the air pumps 505.

[0041] In this embodiment, when the double-sided panel teeth 310 move upward to the maximum limit, the circular gear 502 rotates forward one circle, and the linkage piece 503 pulls the air rod of the air pump 505 to open the air pump 505. When the double-sided panel teeth 310 move downward to the maximum limit, the circular gear 502 rotates backward one circle, and the linkage piece 503 pushes the air rod of the air pump 505 to close the air pump 505.

[0042] Preferably, the double-sided panel teeth 310 are meshed and connected with the circular gear 502. One end of the shaft rod 501 is rotatably installed on one side surface inside the nacelle housing 1, and the other end of the shaft rod 501 is rotatably installed on the other side surface of the nacelle housing 1 through the linkage piece 503.

[0043] In this embodiment, the shaft rod 501 can drive the linkage piece 503 to rotate, and the rotation is proportional to the circular gear 502.

[0044] Preferably, an infrared sensing piece 512 is installed on the outer surface of the stop plate 312, a positioning block 506 is welded and installed on the outer surface of the air pump 505, and the air rod of the air pump 505 is slidably connected to the inner surface of the positioning block 506.

[0045] In this embodiment, the infrared sensing piece 512 can control the operation of the air pump 505 and the electric screw rod 309, and the positioning block 506 ensures the stability of the sliding of the air rod of the air pump 505.

[0046] Preferably, the fixing unit 4 includes a top plate 401 and a vertical fixed-wing drone 409. Rotating pieces 402 are welded and installed on the inner surfaces of the arc-shaped cover plate one 301 and the arc-shaped cover plate two 302. The top plate 401 is rotatably installed on the outer surface of the rotating piece 402. Slide rods 404 are installed in the symmetrically opened grooves on the upper surface of the stop plate 312. Springs 405 are sleeved on the outer surfaces of the slide rods 404, and sliding blocks 406 are slidably installed on the outer surfaces of the slide rods 404.

[0047] In this embodiment, the spring 405 can push the sliding block 406 to reset the shaft pin 407, and the slide rod 404 provides stability and guidance for the sliding of the sliding block 406.

[0048] Preferably, a shaft pin 407 is welded and installed on the outer surface of the sliding block 406, a pin block 408 is installed on the lower surface of the vertical fixed-wing drone 409, and the pin block 408 is snap-fitted on the shaft pin 407.

[0049] In this embodiment, the pin block 408 is snap-fitted on the shaft pin 407 to fix the vertical fixed-wing drone 409.

[0050] Preferably, the top plate 401 and the sliding block 406 are magnetically connected, the pin block 408 and the infrared sensing piece 512 are magnetically connected, and a top piece 403 is welded and installed on the outer surface of the rotating piece 402.

[0051] In this embodiment, the top piece 403 can ensure that the top plate 401 does not sag, so as not to affect the pushing of the sliding block 406.

[0052] Specific usage method of the present invention: When the machine nest is opened, first, the electric screw rod 309 works to drive the double-sided panel gear 310 to move upward. At this time, the moon-shaped gear one 307 and the moon-shaped gear two 308 meshed with the double-sided panel gear 310 perform circular arc motions, so that the arc-shaped rod one 305 and the arc-shaped rod two 306 drive the arc-shaped cover plate one 301 and the arc-shaped cover plate two 302 to rotate outward respectively around the rotation shaft one 303 and the rotation shaft two 304, thereby unfolding the arc-shaped cover plate one 301 and the arc-shaped cover plate two 302. While the double-sided panel gear 310 moves upward, it will drive the flat plate 311 and the stop plate 312 to move upward.

[0053] For cleaning, when the double-sided panel gear 310 moves upward, the double-sided panel gear 310 will drive the circular gear 502 to rotate, thereby driving the shaft rod 501 to rotate. Then, the shaft rod 501 drives the linkage piece 503 to rotate, so that the push rod 504 pulls the pull rod of the air pump 505, starting the air pump 505 to inflate the compression bottle 507 through the hose 508. When the vertical fixed-wing unmanned aerial vehicle 409 descends, the pin block 408 is magnetically attracted and lands on the infrared sensing sheet 512 to achieve the effect of positioning and landing. The infrared sensing sheet 512 senses the magnetically attracted pin block 408. At this time, the compression bottle 507 is started to inflate the straight pipe 509 through the spring pipe 511, and the high-pressure gas is sprayed out dispersedly by the nozzle 510, thereby spraying off the dust carried by the vertical fixed-wing unmanned aerial vehicle 409.

[0054] Closing and fixing: While cleaning the vertical fixed-wing unmanned aerial vehicle 409, the electric screw rod 309 works in the reverse direction. The moon-shaped gear one 307 and the moon-shaped gear two 308 meshed with the double-sided panel gear 310 perform circular arc motions again, so that the arc-shaped rod one 305 and the arc-shaped rod two 306 drive the arc-shaped cover plate one 301 and the arc-shaped cover plate two 302 to rotate outward respectively around the rotation shaft one 303 and the rotation shaft two 304, thereby closing the arc-shaped cover plate one 301 and the arc-shaped cover plate two 302. When closing, the top plate 401 rotatingly installed on the rotating piece 402 pushes the sliding block 406 to compress the spring 405 and slide on the sliding rod 404, thereby clamping the shaft pin 407 on the pin block 408 to fix the vertical fixed-wing unmanned aerial vehicle 409.
