DETAILED DESCRIPTION

[0020] The purpose of the present invention is to provide a multi-rotor UAV platform to reduce the harm caused to the UAV by debris particles blown up in the surroundings.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] A multi-rotor drone is a special unmanned helicopter with three or more rotor shafts. The motor on each shaft drives the rotor to rotate at high speed, thereby generating lift thrust, so that it can take off and land vertically without the need for a catapult or other booster device. In addition, it has the advantages of low noise, small size, and light weight, and is suitable for use on multiple platforms and in multiple spaces.

[0023] Therefore, multi-rotor drones are widely used in many industries. For example, in the agricultural field, they are used to spray pesticides on crops and monitor crop growth; in the environmental protection field, they are used to monitor air, soil, vegetation and water quality, as well as to patrol mountains and forests for fire prevention; in the power field, they are used to patrol power lines and clear debris from transmission lines. Multi-rotor drones have provided great convenience for work in these fields.

[0024] However, this has led to a complex and changeable working environment for multi-rotor drones, and various factors in the surrounding environment directly affect the working status and service life of multi-rotor drones. In particular, when multi-rotor drones take off and land on the landing platform, how to reduce the adverse effects of dust, gravel and other debris blown up by the high-speed rotating rotors on the multi-rotor drones. Therefore, if Figure 1 As shown, an embodiment of the present invention discloses a multi-rotor UAV platform, including a platform device 100, a supporting device 200 and a dust prevention device 300.

[0025] The platform device 100 is provided with a support ring 110 and a take-off and landing plane 120, and the take-off and landing plane 120 is fixed on the support ring 110 for the take-off and landing of the multi-rotor UAV. During the take-off and landing process of the multi-rotor UAV on the platform device 100, the high-speed rotating rotor will generate a downward pressure airflow, thereby causing a ground effect. In order to reduce the ground effect caused by the downward pressure airflow, a vent 121 is provided on the take-off and landing plane 120 to rectify the airflow generated by the rotor, thereby effectively reducing the ground effect and improving the stability and accuracy of the take-off and landing of the multi-rotor UAV.

[0026] The support ring 110 of the platform device 100 is also provided with a support device 200, which supports the platform device 200 on the ground, so that the platform device 100 is away from the ground, thereby reducing the interference of obstacles such as sand, gravel, and weeds on the ground on the multi-rotor drone during the take-off and landing process of the platform device 100. The support device 200 includes a plurality of support rods 210, which are supported at multiple points so that the support device 200 can adapt to complex and changeable ground conditions, thereby improving the stability of the support device 200.

[0027] When the multi-rotor drone takes off and lands on the platform device 100, in order to effectively reduce the damage caused to the multi-rotor drone by the debris particles blown up from the surroundings, a dustproof device 300 is set between the platform device 100 and the ground. The dustproof device 300 blocks the airflow generated by the rotor from the ground, so that the airflow flows from the gap between the platform device 100 and the support device, thereby effectively reducing the damage caused to the multi-rotor drone by the dust and other debris on the ground being blown up by the airflow. In addition, the dustproof device 300 can also effectively isolate foreign matter such as weeds and flying insects on the ground to avoid interference with the take-off and landing process of the multi-rotor drone. Thereby ensuring the safe operation of the multi-rotor drone.

[0028] like Figure 1 As shown, in order to make the dustproof device 300 easy to use, the dustproof device 300 is connected to the supporting device 200. In a specific embodiment, the dustproof device 300 is connected to the supporting rod 210 of the supporting device 200 to fix the dustproof device 300.

[0029] Furthermore, in order to facilitate the assembly and disassembly between the dustproof device 300 and the supporting device 200 and improve work efficiency. A first hanging ring 310 is provided on one of the dustproof device 300 and the supporting device 200, and a first hook that is hooked and matched with the first hanging ring 310 is provided on the other of the dustproof device 300 and the supporting device 200. The dustproof device 300 and the supporting device 200 are detachable and quick to assemble and disassemble, so as to facilitate the maintenance and replacement of the dustproof device. In addition, in order to improve the reliability of the dustproof device 300 and the supporting device 200 after installation, the first hook and the first hanging ring 310 are both multiple, and the number is the same, and they correspond one to one during installation. Alternatively, those skilled in the art may also design other detachable connection methods according to actual needs, which will not be listed one by one in this article.

[0030] When the multi-rotor drone takes off and lands on the take-off and landing plane 120, the strong airflow generated by the high-speed rotating rotor causes disturbance of the dustproof device 300, thereby increasing the instability of the multi-rotor drone take-off and landing platform provided by this embodiment. Therefore, in order to reduce this adverse effect, a first elastic component is provided on the first hook so that after the first hanging ring 310 is hung with the first hook, the first elastic component can tighten the dustproof device. In a specific embodiment, the first elastic component is a tension spring, and the tension spring is connected between the first hook and the dustproof device 300 or the support device 200 installed on the first hook. After the first hanging ring 310 and the first hook are installed, the tension spring is in an elongated state and has a contraction potential energy to tighten the dustproof device 300. Alternatively, those skilled in the art can also design other elastic devices according to actual needs to meet the need to tighten the dustproof device 300, which will not be repeated herein.

[0031] In a specific embodiment, the dustproof device 300 is a dustproof cloth, which is light in material, reducing the weight of the multi-rotor drone platform provided by this embodiment, making it easy to carry and easy to store. Alternatively, the dustproof device 300 is made of a dustproof and moisture-proof material, thereby blocking dust and debris while isolating some of the effects of moisture on the multi-rotor drone, thereby achieving a dustproof and moisture-proof effect.

[0032] In addition, even when the ground is uneven, the take-off and landing plane 120 can still maintain a good horizontal state, so that the multi-rotor drone can be parked stably. Each support rod 210 is a retractable structure. In a specific embodiment, the support rod 210 is multi-section, and one section is nested in the cavity of another section to achieve the length adjustment of the support rod 210, and the height adjustment range is 0m-1m. And each support rod 210 is provided with a locking device to fix the length of the support rod 210 after adjustment. It should be noted that the multi-section threaded matching structure of the support rod 210 realizes the telescopic function, that is, one section of the telescopic rod has a screw hole, and the other section of the telescopic rod has a screw rod, and the length adjustable function is realized by the threaded matching of the screw rod and the screw hole.

[0033] In a specific embodiment, the take-off and landing plane 120 is made of polyamide fiber fabric. Polyamide fiber has good wear resistance, durability, wrinkle resistance and light texture, which increases the service life of the take-off and landing plane 120, while also reducing the weight of the overall device, avoiding the disadvantages of being bulky and difficult to use.

[0034] like Figure 1 As shown, the support rod 210 and the support ring 110 are connected by a T-shaped sleeve 500, and the transverse part of the T-shaped sleeve 500 is sleeved on the support ring 110, and is a clearance fit so that the T-shaped sleeve 500 and the support ring 110 can rotate, and the T-shaped sleeve 500 and the support rod 210 are fixedly matched, thereby realizing the rotatable connection between the support rod 210 and the support ring 110. Then the angle between the support rod 210 and the support ring 110 can be adjusted. In a specific embodiment, the adjustment range of the angle is 0°-100°, so as to further increase the stability of the take-off and landing plane 120 under complex ground conditions. And a fixing device is provided on the T-shaped sleeve 500 to fix the adjusted angle between the support rod 210 and the support ring 110. The fixing device can be a top screw commonly used in the prior art, and the top screw that is threadedly matched with the T-shaped sleeve 500 presses the support ring 110 to achieve the effect of stopping rotation. Those skilled in the art will appreciate that the specific fixing device may be other ones as long as the T-shaped sleeve 500 and the support ring 110 can be fixed.

[0035] Therefore, the length of the support rod 210 of the support device 200 and the angle relative to the support ring 110 can be adjusted. After the support rod 210 is adjusted, the whole presents an outward "eight" shape away from the center of the support ring 110, which is more conducive to the stability of the platform device 100, so that the multi-rotor UAV take-off and landing platform disclosed in the present invention can adapt to various terrains in the wild. For example, in harsh environments such as potholes, weeds, and low bushes in the wild, it can also ensure the safe take-off and landing of multi-rotor unmanned aircraft.

[0036] In addition, one of the first hook and the first hanging ring 310 can be set on the first section of the support rod 210 (the section directly connected to the support ring 110), and the other of the first hook and the first hanging ring is set on the dust and moisture-proof cloth (dust-proof device 300). Therefore, when the support rod 210 is adjusted, it is convenient for the dust and moisture-proof cloth (dust-proof device 300) to be supported and unfolded.

[0037] Similarly, in order to facilitate the disassembly and assembly of the landing plane 120 on the support ring 110, one of the landing plane 120 and the support ring 110 is provided with a second hanging ring, and the other of the landing plane 120 and the support ring 110 is provided with a second hook that is engaged with the second hanging ring. There are multiple second hooks and the second hanging ring, and the number is the same, and they are installed in a one-to-one correspondence.

[0038] The second hook is provided with a second elastic component. After the second hanging ring is hung with the second hook, the second elastic component is used to tighten the take-off and landing plane 120, reduce the disturbance of the airflow to the take-off and landing plane 120 during the take-off and landing of the multi-rotor drone, and reduce the collapse of the take-off and landing plane 120 due to gravity when the multi-rotor drone is parked on the take-off and landing plane 120. In addition, in a specific embodiment, the first elastic component can also be a tension spring, and the tension spring is connected between the second hook and the take-off and landing plane 120 or the support ring 110 where the second hook is installed. After the second hanging ring and the second hook are installed, the tension spring is in an elongated state and has a contraction potential energy to tighten the take-off and landing plane 120. Alternatively, those skilled in the art can also design other elastic devices according to actual needs to meet the tightening requirements of the take-off and landing plane 120, which will not be repeated herein.

[0039] In order to facilitate the storage of the support ring 110, the support ring 110 includes a plurality of assembly blocks, and each assembly block is connected head to tail in sequence by a snap-fit ​​method to form a ring. In a specific embodiment, the head end portion of the assembly block is nested in the cavity of the tail end portion of the connected assembly block, and a snap-fit ​​protrusion is provided in the direction of the cavity at the tail end portion of the assembly block, and a snap-fit ​​groove matching the snap-fit ​​protrusion is provided at the head end portion of the assembly block to achieve the snap-fit ​​connection of adjacent assembly blocks. In addition, the material of the support ring 110 is polyvinyl chloride (PVC), which has good stability, strong compression, tension and impact resistance, and certain flexibility, so it is convenient for each assembly block to be snap-fitted and used, and the service life is enhanced. Alternatively, those skilled in the art can design other connection methods according to actual needs, and it is necessary to ensure that each assembly block can be detachably connected to facilitate the storage and use of the support ring 110.

[0040] In another specific embodiment, the support ring 110 is a circular ring of polyvinyl chloride (PVC), and the diameter of the support ring 110 is 60 cm to meet the width required for take-off and landing of micro or small multi-rotor drones at this stage, and the number of assembly blocks of the support ring 110 is four, so that after disassembly, the four assembly blocks can be folded and stacked to a quarter of the area of ​​the original support ring 110 for easy carrying and storage. Of course, it is understandable that those skilled in the art can design the diameter range of the support ring 110 and the number of assembly blocks according to actual needs.

[0041] like Figure 1 As shown, in order to make the multi-rotor UAV take off and land smoothly and safely at night or in a dim environment, a lighting device 400 for marking and lighting is provided on the support ring 110, and the lighting device 400 is provided in multiples. In a specific embodiment, the lighting device 400 is a laser lamp and is placed above the connection between each support rod 210 and the support ring 110 to form a square array of lamp posts to indicate the direction for the take-off and landing of the multi-rotor UAV, and then mark the landing position for the multi-rotor UAV at night or in a dim environment. The light of the laser lamp has the advantages of high brightness, good designation, long range and strong penetration. Further, in order to enhance the marking effect, the light color can be selected as red, green or other colors or a combination of different colors. The power supply device 600 that provides energy for the lighting device 200 is arranged on the support rod 210.

[0042] Therefore, in summary of the above embodiments, the multi-rotor UAV take-off and landing platform disclosed in the present invention has the following specific steps for use: Step 1: Open the adjustable support rod 210 and adjust the height according to actual needs, then adjust the plane where the platform device 100 is located to a horizontal plane, and finally check the stability of the support device 200; Step 2: Hang the dust and moisture-proof cloth (dust-proof device 300) with the first section of the support rod 210, and carefully check to ensure that the hanging is firm and reliable; Step 3: At night or in a dim environment, turn on the power supply device 600 and the lighting device 400 to mark the location of the multi-rotor UAV take-off and landing platform disclosed in the present invention to facilitate the take-off and landing of the multi-rotor UAV; Step 4: After the inspection work is completed, turn off the power supply device 600, retract the support rod 210, and then disassemble the dustproof device 300 on the lower layer and the platform device 100 on the upper layer, and store them in a special bag.
