Description

Technical Field

[0001] The present invention mainly relates to the technical field of unmanned aerial vehicles (UAVs), and specifically relates to an intelligent unmanned site monitoring UAV. Background Art

[0002] Power facilities are an important part of the power industry. From power plants to substations, distribution stations, and then to the power equipment of each user, power facilities require efficient and stable operation. Traditional power facility monitoring methods mainly rely on manpower, but in today's highly digital and intelligent era, traditional inspection methods have gradually exposed many disadvantages such as low efficiency, high cost, and high risk. The drone intelligent inspection system, with its unique advantages such as high efficiency, accuracy, and safety, is setting off a revolution in inspection models in all walks of life.

[0003] Unmanned aerial vehicles, also known as "drones", are unmanned aerial vehicles that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers.

[0004] The landing gear of some drones only consists of two relatively retractable rods, with springs connected between the two rods to absorb the impact of landing. Some drones even have only a few rod-shaped support legs made of plastic. When landing, the elasticity of the material itself is directly used to absorb the impact during landing. The cushioning effect on drones is very limited, causing drones to bounce and roll after touching the ground during landing, resulting in damage to the drones and affecting the station monitoring of drones. Summary of the invention

[0007] Preferably, a plurality of air inlet holes are provided on the lower side of the installation box, and a driving motor is provided inside the installation box, and the driving motor drives the fan blade shaft to rotate and causes the fan blades to generate airflow.

[0008] Preferably, a winding rack and a wind block plate are provided on one side of the camera housing, a cover cloth is wound up inside the winding rack by a coil spring, the other end of the cover cloth is mounted on the wind block plate, a slide groove is provided on the camera housing for the wind block plate to slide, and a spring connected to the wind block plate is provided inside the slide groove, and the air nozzle is facing the wind block plate.

[0009] Preferably, the upper shaft is connected to the axis of the fan blade shaft, and a fixedly mounted conical ring disk and a rotatably mounted circular ring disk are provided on the upper shaft, and the circular ring disk slides up and down on the upper shaft, and a plurality of support rods are provided between the conical ring disk and the circular ring disk, and a plurality of sliding grooves are provided on the conical ring disk, and the plurality of sliding grooves are distributed in a circle around the upper shaft, and the plurality of support rods slide in the plurality of sliding grooves respectively, and the circular ring disk and the plurality of support rods are only in contact with each other.

[0010] Preferably, a bevel gear set is provided above each of the hollow cylinders, and the bevel gear set consists of two bevel gears meshing with each other, one of the bevel gears is connected to the axis of the screw sleeve, and the other bevel gear is connected to the axis of a follower gear, and a rack is meshed on one side of the follower gear, and the rack and the annular disk are connected by a connecting rod, and several of the connecting rods rotate around the axis of the annular disk.

[0011] Preferably, a spiral pattern is provided on the inner side wall of the main sleeve, a rolling ball slides on the spiral pattern, and the rolling ball is installed on the side wall of the slide rod.

[0012] Preferably, a rotating ring is installed on the main sleeve, and one side of the rotating ring is installed at the lower end of the drone body through a mounting frame, a slot is provided at the top end of the main sleeve, and an insert block is slidable inside the slot, a slot block matched with the insert block is provided at the upper end of the slide rod, a return spring is connected between one side of the insert block and the inner wall of the slot, an air guide tube is connected to the enclosed space formed between one side of the insert block and the inner wall of the slot, two pneumatic rods are connected between the annular disk and the lower end of the drone body, the other end of the air guide tube is connected to a rotating joint on the axis line of the main sleeve, and the rotating joint is connected to the pneumatic rod through a connecting pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) When the drone is landing, the foot bar contacts the ground first. As the drone continues to descend, the slide bar continues to penetrate the main sleeve, causing the main sleeve to rotate, driving the follower gear ring to rotate, driving the central gear ring to select, and driving the canvas to rotate. The rotation of the canvas will produce strong resistance with the gas, forcing the drone to descend smoothly, effectively absorbing the impact of the drone during landing, thereby avoiding bouncing and rolling during the landing of the drone, which is beneficial to protecting the drone and preventing the drone from being damaged during landing; (2) When the UAV takes off, the drive motor is started first. As the drive motor drives the fan shaft to rotate, the upper shaft will rotate accordingly, causing the conical ring disk to rotate. As the support rod slides on the conical ring disk, the support rod moves outward under the influence of centrifugal force and pushes the circular ring disk upward. The circular ring disk drives the rack upward, causing the follower gear to drive the screw sleeve to rotate through the bevel gear set, causing the screw to continuously retract, thereby retracting the canvas and preventing it from unfolding. While the circular ring disk moves upward, the pneumatic rod is squeezed, sending gas into the enclosed space formed between the insert block 322 and the inner wall of the slot, causing the reset spring to be compressed, and the insert block jams the card slot block, preventing the slide rod from sliding out of the main sleeve. At this time, the canvas is not unfolded, and the slide rod is located inside the main sleeve, reducing the air resistance of the UAV as much as possible. (2) In the initial state, the cover cloth covers the camera to protect it and prevent foreign objects from adhering to it. When the drone takes off, the drive motor is started first. The drive motor drives the fan shaft to rotate and causes the fan blades to rotate to generate airflow. The generated airflow enters the air nozzle and blows out along the guide plate and guide pipe. The wind deflector moves under the influence of the airflow and causes the spring in the slide to contract. At this time, the cover cloth no longer protects the camera, but there will always be airflow flowing on the surface of the camera. The flowing airflow forms a new protection for the camera to prevent foreign objects from adhering to the camera. Compared with the traditional scraper form, the airflow protection can avoid the temporary impact of the scraper on the camera's shooting when scraping. When the drone is about to land, the drive motor stops running and the spring in the slide is reset, so that the cover cloth covers the camera again to protect it.

[0017] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0020] Example 1: Please refer to the attached Figure 1 - Figure 3 A smart unmanned station monitoring drone comprises a drone body 1 and a camera assembly 2 arranged at the lower end of the drone body 1. A cleaning mechanism is arranged on one side of the camera assembly 2. The cleaning mechanism comprises a mounting box 201 arranged at the lower end of the drone body 1. A fan shaft 202 and a plurality of fan blades 203 installed on the fan shaft 202 are arranged inside the mounting box 201. A guide plate 204 located inside the mounting box 201 is arranged above the fan blades 203. A guide tube 205 is connected to the center of the guide plate 204. The camera assembly 2 comprises an adjustment frame 206 connected to the drone body 1. A camera housing 207 is installed on the adjustment frame 206. A camera 20 is arranged inside the camera housing 207. 8. An air blowing nozzle 212 is installed on the adjustment frame 206 and the camera housing 207, and the guide tube 205 is connected to the air blowing nozzle 212; a plurality of air inlet holes are provided on the lower side of the installation box 201, and a driving motor is provided inside the installation box 201, and the driving motor drives the fan shaft 202 to rotate and makes the fan blades 203 generate airflow; a winding frame 209 and a wind blocking plate 210 are provided on one side of the camera housing 207, and a cover cloth 211 is wound up inside the winding frame 209 through a coil spring, and the other end of the cover cloth 211 is installed on the wind blocking plate 210, and a slide groove is provided on the camera housing 207 for the wind blocking plate 210 to slide, and a spring connected to the wind blocking plate 210 is provided inside the slide groove, and the air blowing nozzle 212 is directly opposite to the wind blocking plate 210.

[0021] In the initial state, the cover cloth 211 covers the camera 208 to protect the camera 208 and prevent foreign matter from adhering to the camera 208; When the drone takes off, the driving motor is started first, and the driving motor drives the fan shaft 202 to rotate and the fan blades 203 to rotate to generate airflow. The generated airflow enters the air nozzle 212 along the guide plate 204 and the guide tube 205 and is blown out. The wind blocking plate 210 moves under the influence of the airflow, and the spring in the slide slot contracts. At this time, the cover cloth 211 no longer protects the camera 208, but there will always be flowing airflow on the surface of the camera 208. The flowing airflow forms a new protection for the camera 208 to prevent foreign matter from adhering to the camera 208. Compared with the traditional scraper form, the protection of the airflow can avoid the temporary influence on the shooting of the camera 208 when the scraper is scraped; When the drone is about to land, the driving motor stops running, and the spring in the slide slot returns to its original position, so that the cover cloth 211 covers the camera 208 again to protect the camera 208. Example 2: Based on Example 1, please refer to the attached Figure 1 - Figure 6 The upper shaft 301 is connected to the fan shaft 202 axially, and a fixed cone ring disk 303 and a rotatably mounted circular ring disk 304 are provided on the upper shaft 301, and the circular ring disk 304 slides up and down on the upper shaft 301, and a plurality of support rods 305 are provided between the cone ring disk 303 and the circular ring disk 304, and a plurality of sliding grooves are provided on the cone ring disk 303, and the plurality of sliding grooves are distributed in a circle around the upper shaft 301, and a plurality of support rods 305 slide inside the plurality of sliding grooves respectively, and the circular ring disk 304 and the plurality of support rods 305 only contact each other. Since the driving motor drives the fan shaft 202 to rotate, the upper shaft 301 will rotate accordingly, so that the cone ring disk 303 rotates, and since the support rods 305 slide on the cone ring disk 303, under the influence of centrifugal force, the support rods 305 move outward and push the circular ring disk 304 upward.

[0022] Please refer to the attached Figure 3 - Figure 6Two groups of tripods 3 are arranged at the lower end of the drone body 1, and a slow-down mechanism is arranged between the two groups of tripods 3. The slow-down mechanism includes an upper shaft 301 and a lower shaft 302 that are rotatably connected. A central gear ring 306 is installed on the lower shaft 302. Two hollow cylinders 307 are penetrated through the central gear ring 306. A fixing plate 308 is installed inside each hollow cylinder 307. A screw sleeve 309 is rotatably installed at the lower end of the fixing plate 308. A screw rod 310 is threadedly connected to the screw sleeve 309. A curling sleeve 311 is installed on the side walls of the two hollow cylinders 307. The curling sleeve 311 is provided with a spring installed inside. The hollow cylinder 307 is provided with a curling rod, and a canvas 312 is wound on the curling rod, and the other end of the canvas 312 is connected to the stretching rod 313, and the stretching rod 313 is installed at the lower ends of the two screw rods 310; each hollow cylinder 307 is provided with a bevel gear set 314 above, and the bevel gear set 314 is two mutually meshing bevel gears, one of which is connected to the axis of the screw sleeve 309, and the other bevel gear is connected to the axis of the follower gear 315, and a rack 316 is meshed on one side of the follower gear 315, and the rack 316 and the circular ring disk 304 are connected by a connecting rod, and a plurality of connecting rods rotate around the axis of the circular ring disk 304. The circular ring disk 304 drives the rack 316 to move upward, so that the follower gear 315 drives the screw sleeve 309 to rotate through the bevel gear set 314, so that the screw rod 310 is continuously retracted, so that the canvas 312 is recovered or unfolded.

[0023] Please refer to the attached Figure 3 - Figure 6Each set of supporting legs 3 includes a foot cross bar 317, and a main support rod 318 and two auxiliary support rods 319 installed on the foot cross bar 317. The two auxiliary support rods 319 are telescopic rods and are installed on the front and rear sides of the foot cross bar 317. The main support rod 318 includes a main sleeve 325 and a sliding rod 320 sliding inside the main sleeve 325. The main sleeve 325 is provided with a follower gear ring 326 on its outer cover, and the follower gear ring 326 is meshed with the center gear ring 306. The inner side wall of the main sleeve 325 is provided with a spiral pattern, and a rolling ball 321 slides on the spiral pattern. The rolling ball 321 is installed on the side wall of the slide bar 320. A rotating ring is installed on the main sleeve 325, and one side of the rotating ring is installed on the lower end of the drone body 1 through a mounting frame. A slot is provided at the top of the main sleeve 325, and an insert block 322 slides inside the slot. A card slot block matching the insert block 322 is provided at the upper end of the slide bar 320. A return spring 323 is connected between one side of the insert block 322 and the inner wall of the slot. An air guide tube is connected to the closed space formed between one side of the insert block 322 and the inner wall of the slot. Two gas pressure rods 324 are connected between the annular disk 304 and the lower end of the drone body 1. The other end of the air guide tube is connected to the rotating joint on the axis of the main sleeve 325, and the rotating joint is connected to the gas pressure rod 324 through a connecting pipe. A blocking block should be provided at the bottom of the spiral pattern to prevent the slide bar 320 from completely sliding out of the main sleeve 325. When the annular disk 304 moves upward, the pneumatic rod 324 is squeezed, and the gas is sent into the enclosed space formed between the plug block 322 and the inner wall of the slot, so that the reset spring 323 is compressed, and the plug block 322 jams the slot block, so that the slide bar 320 cannot slide out of the main sleeve 325. At this time, the canvas 312 is not unfolded, and the slide bar 320 is located inside the main sleeve 325, so that the air resistance of the drone is reduced as much as possible; when the drone lands, the foot cross bar 317 contacts the ground first, and as the drone continues to descend, the slide bar 320 continues to penetrate into the main sleeve 325, so that the main sleeve 325 rotates, driving the follower gear ring 326 to rotate, driving the central gear ring 306 to select, and driving the canvas 312 to rotate. The rotation of the canvas 312 will produce strong resistance with the gas, forcing the drone to descend smoothly. The specific operation steps of the present invention are: When the drone takes off, the driving motor is started first, and the driving motor drives the fan shaft 202 to rotate and the fan blades 203 to rotate to generate airflow. The generated airflow enters the air nozzle 212 along the guide plate 204 and the guide tube 205 and is blown out. The wind blocking plate 210 moves under the influence of the airflow, and the spring in the slide slot contracts. At this time, the cover cloth 211 no longer protects the camera 208, but there will always be flowing airflow on the surface of the camera 208. The flowing airflow forms a new protection for the camera 208 to prevent foreign matter from adhering to the camera 208. Compared with the traditional scraper form, the protection of the airflow can avoid the temporary influence on the shooting of the camera 208 when the scraper is scraped; At the same time, since the driving motor drives the fan shaft 202 to rotate, the upper shaft 301 will rotate accordingly, causing the cone ring disk 303 to rotate. Since the support rod 305 slides on the cone ring disk 303, under the influence of centrifugal force, the support rod 305 moves outward and pushes the circular ring disk 304 to move upward. The circular ring disk 304 drives the rack 316 to move upward, so that the follower gear 315 drives the screw sleeve 309 to rotate through the bevel gear set 314, allowing the screw 310 to continuously retract, thereby The canvas 312 is retracted so that the canvas 312 is not unfolded. When the annular disk 304 moves upward, the pneumatic rod 324 is squeezed, and the gas is sent into the closed space formed between the insert block 322 and the inner wall of the slot, so that the return spring 323 is compressed, and the insert block 322 blocks the card slot block, so that the slide bar 320 cannot slide out of the main sleeve 325. At this time, the canvas 312 is not unfolded, and the slide bar 320 is located inside the main sleeve 325, so that the air resistance of the drone is reduced as much as possible; When the drone is about to land, the driving motor stops running, and the spring in the slide slot is reset, so that the cover cloth 211 covers the camera 208 again to protect the camera 208; at the same time, the support rod 305 is reset, and the annular disk 304 moves down, so that the canvas 312 is unfolded, and the insert block 322 is separated from the card slot block, and the slide rod 320 slides out of the main sleeve 325; When the UAV is landing, the foot cross bar 317 contacts the ground first, and as the UAV continues to descend, the slide bar 320 continues to penetrate into the main sleeve 325, so that the main sleeve 325 rotates, driving the follower gear ring 326 to rotate, driving the central gear ring 306 to select, and driving the canvas 312 to rotate. The rotation of the canvas 312 will produce a strong resistance with the gas, forcing the UAV to descend smoothly.

[0024] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
