The control panel 109 is fixedly installed on the surface of the top plate 108. The lifting platform 110 is fixedly connected to the middle of the top surface of the top plate 108. The top plate 108 also includes an adjustment component, a limit component, and a drive component. The adjustment component is set on the bottom plate 1 to control the height of the top plate 108. The limit component is set on the top surface of the top plate 108 for use. The drive component is set on the top plate 108 for use with the limit component.

[0029] It should be noted that the control panel 109, the first motor 201, and the second motor 412 are electrically connected by wires. The specific working principles are based on existing technology and will not be elaborated on here. The operation of the first motor 201 facilitates the control of the height of the top plate 108, and the operation of the second motor 412 facilitates the flipping of the baffle 402.

[0030] Furthermore, the adjustment assembly includes a main shaft 2 rotatably connected to the middle of the base plate 1. The bottom end of the main shaft 2 is fixedly connected to the output end of the first motor 201, which is fixedly installed in the middle of the bottom surface of the base plate 1. A gear disk 202 is fixedly connected to the top of the main shaft 2. First gear plates 203 mesh on both sides of the gear disk 202. A side plate 204 is fixedly connected to the opposite side of the first gear plate 203. A guide groove 205 is provided on the side plate 204.

The two ends of the crossbar 208 are fixedly connected to the mounting base 209. The mounting base 209 is rotatably connected to the pulley 210, which is slidably connected to the slide rod 211. The two ends of the slide rod 211 are fixedly connected to the first shaft seat 212. The bottom surface of the first shaft seat 212 is fixedly connected to the base plate 1.

[0031] When the height of the top plate 108 needs to be controlled, the first motor 201 on the bottom surface of the bottom plate 1 operates. The operation of the first motor 201 causes the gear disk 202 on the main shaft 2 to rotate. The gear disk 202 is engaged with a first toothed plate 203. The rotation of the gear disk 202 causes the first toothed plate 203 to move. A side plate 204 is fixedly connected to one side of the first toothed plate 203, and a guide groove 205 is provided on the side plate 204. A limiter is slidably connected inside the guide groove 205. The movement of the first toothed plate 203 causes the inner wall of the guide groove 205 to move against the limiting rod 206. The movement of the first toothed plate 203 causes the crossbar 208 on the fixed plate 207 to move, thereby facilitating the sliding of the pulley 210 on the mounting base 209 on the sliding rod 211. The sliding of the sliding rod 211 causes the third linkage plate 214 on the pin 213 to push the top plate 108 of the third hinge seat 215 to move, thereby facilitating the control of the height of the top plate 108.

[0032] Furthermore, the limiting component includes a second bearing 3 fixedly mounted on the top plate 108. A driven wheel 301 is rotatably connected to the second bearing 3.

Limiting plates 308 are fixedly connected to both sides of the mating plate 307. Rollers 309 are rotatably connected to both ends of the limiting plate 308. The rollers 309 are attached to the inner wall of the arc plate 302.

[0033] A second bearing seat 3 is fixedly connected to the top plate 108, and a driven wheel 301 is rotatably connected to the top of the second bearing seat 3. The driven wheel 301 is attached to the arc-shaped plate 302. A groove 303 is provided on the arc-shaped plate 302, and a threaded post 304 is provided inside the groove 303. A thread is provided on the threaded post 304, and a nut 305 is threadedly connected to the threaded post 304. Rotating the nut 305 rotatably connects to the bottom end of the nut 305. A sleeve 306 is provided, and the bottom end of the sleeve 306 is fixedly connected to the mating plate 307. The rotation of the nut 305 causes the sleeve 306 to drive the mating plate 307 to move. Limiting plates 308 are fixedly connected to both sides of the mating plate 307, and rollers 309 are rotatably connected to both ends of the limiting plates 308. The movement of the mating plate 307 causes the rollers 309 on the limiting plates 308 to fit against the inner wall of the arc plate 302, increasing the stability of the rotation of the arc plate 302.

[0034] Furthermore, the drive assembly includes a frame 4 fixedly mounted on the arc-shaped plate 302. One end of the frame 4 is fixedly connected to a carrying plate 401, and a baffle 402 is fixedly connected to one side of the carrying plate 401. A connector 403 is fixedly connected to the frame 4, and the other end of the connector 403 is fixedly connected to a second toothed plate 404. A gear 405 meshes on the second toothed plate 404, and the gear 405 is fixedly connected to a driven rod 406. Both ends of the driven rod 406 are rotatably connected to a third bearing 407, and the bottom end of the third bearing 407 is fixedly connected to a top plate 108. One end of the driven rod 406 is fixedly connected to a first pulley 408, and a transmission belt 409 is sleeved on the first pulley 408. The other end of the transmission belt 409 is sleeved on a second pulley 410, and the second pulley 410 is fixedly connected to a drive rod 411. One end of the drive rod 411 is fixedly connected to the output end of a second motor 412, and the second motor 412 is fixedly mounted on the top plate 108.

[0035] When the arc-shaped plate 302 rotates, the second motor 412 operates, causing the drive rod 411 to rotate. One end of the drive rod 411 is fixedly connected to the second pulley 410. The rotation of the drive rod 411 causes the second pulley 410 to rotate. A transmission belt 409 is fitted onto the second pulley 410, and the other end of the transmission belt 409 is fitted onto the first pulley 408. The rotation of the second pulley 410 drives the first pulley 408 to rotate via the transmission belt 409. Wheel 408 is fixedly connected to driven rod 406. The rotation of first pulley 408 drives driven rod 406 to rotate. Gear 405 is fixedly connected to driven rod 406, and gear 405 meshes with second toothed plate 404. The rotation of driven rod 406 drives second toothed plate 404 to rotate through gear 405, thereby facilitating the rotation of frame 4 on second toothed plate 404 as a whole, and facilitating the push of baffle 402 to the top position of top plate 108 to block the UAV on landing platform 110.

[0036] Working principle of the invention: When the height of the top plate 108 needs to be controlled, the first motor 201 on the bottom surface of the bottom plate 1 operates. The operation of the first motor 201 causes the gear disk 202 on the main shaft 2 to rotate. The gear disk 202 is engaged with a first toothed plate 203. The rotation of the gear disk 202 causes the first toothed plate 203 to move. A side plate 204 is fixedly connected to one side of the first toothed plate 203, and a guide groove 205 is provided on the side plate 204. A sliding connection is made inside the guide groove 205. The movement of the limiting rod 206 and the first toothed plate 203 causes the inner wall of the guide groove 205 to move against the limiting rod 206. The movement of the first toothed plate 203 causes the crossbar 208 on the fixed plate 207 to move, thereby facilitating the sliding of the pulley 210 on the mounting base 209 on the sliding rod 211. The sliding of the sliding rod 211 causes the third linkage plate 214 on the pin 213 to push the top plate 108 of the third hinge base 215 to move, thereby facilitating the control of the height of the top plate 108.

[0037] A second bearing seat 3 is fixedly connected to the top plate 108, and a driven wheel 301 is rotatably connected to the top of the second bearing seat 3. The driven wheel 301 is attached to the arc-shaped plate 302. A groove 303 is provided on the arc-shaped plate 302, and a threaded post 304 is provided inside the groove 303. A thread is provided on the threaded post 304, and a nut 305 is threadedly connected to the threaded post 304. When the nut 305 is rotated, a sleeve is rotatably connected to the bottom end of the nut 305. The sleeve 306 is fixedly connected to the bottom end of the connecting plate 307. The rotation of the nut 305 causes the sleeve 306 to drive the connecting plate 307 to move. Limiting plates 308 are fixedly connected to both sides of the connecting plate 307, and rollers 309 are rotatably connected to both ends of the limiting plates 308. The movement of the connecting plate 307 causes the rollers 309 on the limiting plates 308 to fit against the inner wall of the arc plate 302, increasing the stability of the rotation of the arc plate 302.

[0038] When the arc-shaped plate 302 rotates, the second motor 412 operates, causing the drive rod 411 to rotate. One end of the drive rod 411 is fixedly connected to the second pulley 410. The rotation of the drive rod 411 causes the second pulley 410 to rotate. A transmission belt 409 is fitted onto the second pulley 410, and the other end of the transmission belt 409 is fitted onto the first pulley 408. The rotation of the second pulley 410 drives the first pulley 408 to rotate via the transmission belt 409. The first pulley 408 is fixedly connected to the driven rod 406. The rotation of the first pulley 408 drives the driven rod 406 to rotate. A gear 405 is fixedly connected to the driven rod 406, and the gear 405 meshes with the second toothed plate 404. The rotation of the driven rod 406 drives the second toothed plate 404 to rotate through the gear 405, thereby facilitating the rotation of the frame 4 on the second toothed plate 404 as a whole. This makes it easier for the baffle 402 to be pushed to the top position of the top plate 108 to block the drone on the landing platform 110.
