Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a safe landing protection device for electric power inspection UAVs. Background Art

[0002] As the name implies, drones are unmanned aircraft. As drone technology matures, manufacturing costs and entry barriers are reduced, the consumer drone market has exploded, and the civil drone market is on the eve of an explosion. As a type of civil drone, power inspection drones are used in power inspection environments. The purpose of power inspection is to grasp the operating status of the line, promptly discover equipment defects and problems that threaten line safety. Since overhead lines are widely distributed and operate in the open air for a long time, they are often affected by changes in the surrounding environment and nature. Since the types of distribution line equipment are more complex than those of transmission lines, in addition to inspecting the transmission lines, special equipment should be inspected during inspections. It is outdated for staff to observe, inspect and measure the various components of the transmission lines with their eyes or telescopes and other tools and instruments. Today, with the rapid development of high technology, drone inspections have entered the power inspection market. During the inspection, it is necessary to protect the expensive drones to avoid damage to the drones caused by their rapid fall. Therefore, a safe landing protection device for power inspection drones is provided.

[0003] The power inspection UAV controls the rotation speed of the blades when landing. The situation is complicated when flying in the air, especially the complex environment during power inspection, which can easily cause the UAV to be damaged and unable to land normally. The impact force generated by a direct fall will damage other important parts of the UAV, making the UAV unrepairable.

[0004] In a solution for a parachute-type UAV with publication number CN108100265A, the safe landing protection device is directly installed inside the equipment, which will result in the production of the UAV and the production of the safe landing protection device being carried out at the same time, and the safe landing protection device cannot be installed additionally for use; in the parachute protection device solution for the power inspection UAV with publication number: CN113148185A, the compatibility with different models of UAVs is poor, and the UAV needs to have a matching installation platform, which makes the equipment too limited during installation.

[0005] In addition, if the landing space of the drone is not enough, the parachute may not be fully deployed. If the deployment is incomplete, the parachute cannot protect the drone, which may also cause damage to the drone. In response to the above problems, an innovative design is made based on the original power inspection drone safety landing protection device. Summary of the invention

[0047] See also Figure 1-8 The present invention provides a technical solution: a safe landing protection device for an electric power inspection UAV, comprising a body 1 and a mounting platform 2 arranged on the upper side thereof, propellers 101 are installed at the four corners of the body 1, and a placing platform 102 is connected to both sides of the lower end of the body 1, and a mounting rod 3 is arranged on the side of the mounting platform 2, and the mounting rod 3 is set as a "U"-shaped structure, and a threaded area 301 is arranged on the "U"-shaped structure mounting rod 3, which can match bodies 1 of different specifications through nuts 302 matching therewith on the threaded area 301, thereby improving the adaptability of the device to be installed on UAVs of different specifications, threaded areas 301 are arranged at the upper ends of both sides of the mounting rod 3, and nuts 302 matching therewith are connected to the threaded areas 301, and a rubber strip 303 of a wrapping structure is installed at the middle part of the lower end of the mounting rod 3, and the rubber strip 303 wrapped and installed at the middle part of the lower end of the mounting rod 3 fits the UAV, providing reliability for the stable installation between the safe landing protection device and the UAV.

[0048] A folding frame 4 is installed at the upper edge of the mounting platform 2, and an electric telescopic rod 5 is connected to the side of the folding frame 4. The folding frame 4 forms a telescopic folding structure through the electric telescopic rod 5. The electric telescopic rod 5 is arranged on the side of the folding frame 4, and the folding frame 4 can be unfolded by the electric telescopic rod 5. When not in use, the folding frame 4 is folded to the maximum extent to reduce the wind resistance of the UAV flight. A linkage platform 6 is installed on the inner wall of the upper end of the folding frame 4, and the linkage platform 6 is fixedly connected to the top of the folding frame 4. When in use, the folding frame 4 is quickly unfolded by the electric telescopic rod 5 to quickly lift the linkage platform 6 fixedly connected to the top of its upper end, so as to avoid the parachute body 706 from intersecting with the propeller 101 that is still running when it is unfolded, thereby improving the reliability of the unfolding of the parachute body 706.

[0049] A storage bin 7 is provided in the middle of the linkage platform 6, and a main cover 8 is connected to the top of the storage bin 7. The main cover 8 and the storage bin 7 are closely connected, and the main cover 8 forms a rotating connection structure with the storage bin 7 through a rotating rod 602, so that the main cover 8 can support the storage bin 7 to limit the close-fitting cover 701 when not in use.

[0050] A limit ring 201 is installed at the junction of the mounting platform 2 and the mounting rod 3, a control module 202 is provided on the mounting platform 2, and a supplementary fan 203 is installed in the middle area of ​​the mounting platform 2. The supplementary fan 203 installed in the middle area of ​​the mounting platform 2 is operated to provide a precise channel of wind flow for the parachute 706 during the unfolding process, assist the parachute 706 to unfold quickly, provide dual-channel wind direction, and improve the success rate of the unfolding of the parachute 706. An air inlet net 206 is opened at the lower end of the mounting platform 2 close to the supplementary fan 203;

[0051] The linkage platform 6 is provided with a servo motor 601 at the side of the storage bin 7 , the output end of the servo motor 601 is connected with a rotating rod 602 , the middle of the rotating rod 602 is penetrated by a stabilizing frame 603 installed on the linkage platform 6 , and the top end of the rotating rod 602 is fixed to the main cover 8 .

[0052] In this example, a support foot 204 is distributed at the lower end of the mounting platform 2, and a rubber pad 205 is attached to the lower end of the support foot 204. The support foot 204 is set to a "V"-shaped structure. The support foot 204 with the "V"-shaped structure elastically supports the mounting platform 2, and can still be connected to it when the upper surface of the drone is uneven. The rubber pad 205 increases the stability of the connection.

[0053] In this example, a spring 703 is installed at the bottom end of the storage bin 7, a supporting seat 704 is installed on the spring 703, a traction rope 705 is distributed on the supporting seat 704, an umbrella body 706 is connected to the traction rope 705, the supporting seat 704 and the storage bin 7 are nested and slidably connected, and the supporting seat 704 forms a telescopic structure with the storage bin 7 through the spring 703. When the spring 703 loses its limit, the supporting seat 704 can be quickly pushed out to assist the umbrella body 706 to open the umbrella.

[0054] In this example, a matching fitting cover 701 is provided at the top of the storage bin 7. The matching fitting cover 701 provided at the top of the storage bin 7 can be buckled at the top of the storage bin 7 after the umbrella body 706 is stored, so as to avoid friction with the umbrella body 706 when the main cover 8 rotates, thereby providing protection for the umbrella body 706. The side of the fitting cover 701 is connected with a tie rope 702 fixed to the storage bin 7, so as to prevent the fitting cover 701 from falling off and being lost.

[0055] Working principle: According to Figure 2 , Figure 4 and Figure 5As shown, the mounting platform 2 and the machine body 1 are mounted, the mounting rod 3 is taken out and inserted into the limiting ring 201 on the side of the mounting platform 2 from the bottom end of the machine body 1, and then the nut 302 is taken out and adjusted and tightened in the threaded area 301. While tightening, the support foot 204 at the lower end of the mounting platform 2 is pressed against the upper end of the machine body 1, and the rubber pad 205 on the support foot 204 improves the stability and reliability between it and the machine body 1. At this time, the installation between the mounting platform 2 and the machine body 1 is completed;

[0056] according to Figure 1-6 As shown, when the fuselage 1 needs to use landing protection, the control module 202 first triggers the supplementary fan 203 and the electric telescopic rod 5 to operate, and the electric telescopic rod 5 unfolds the folding frame 4 so that the linkage platform 6 fixedly connected to the top of its upper end is quickly lifted, and the folding frame 4 is fully unfolded to prevent the parachute body 706 from intersecting with the propeller 101 that is still running when it is unfolded;

[0057] according to Figure 7-8 As shown, the servo motor 601 drives the rotating rod 602 to rotate stably on the stabilizing frame 603, and at the same time, the main cover 8 at the upper end of the rotating rod 602 will gradually leave the top of the storage bin 7, and the spring 703 will rebound quickly and push out the supporting seat 704 after the fitting cover 701 loses its limit. The parachute body 706 is subjected to the impact force when the body 1 falls, and the supplementary fan 203 running at the same time quickly agitates the parachute body 706 to unfold on the traction rope 705, and the placing platform 102 on the auxiliary body 1 slowly lands on the ground;

[0058] according to Figure 6-8 As shown, after unfolding, the umbrella body 706 needs to be stored for the next use. When storing, the umbrella body 706 and the supporting seat 704 are pushed into the storage bin 7, and then the fitting cover 701 is covered in the storage bin 7 and the servo motor 601 is started to drive the main cover 8 on the rotating rod 602 to cover the storage bin 7, and the fitting cover 701 is limited to achieve the storage of the umbrella body 706.
