Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicle inspection, and in particular relates to a railway inspection unmanned aerial vehicle data collection device. Background Art

[0002] Railway inspection drones are a new and highly efficient tool for railway operations and maintenance. Leveraging advanced equipment such as high-resolution cameras, infrared thermal imagers, and lidar, they can play a vital role in railway inspection, construction monitoring, and emergency rescue. These drones achieve autonomous flight through a flight control system, transmitting high-definition images and sensor data to ground control centers in real time. This allows personnel to promptly identify safety hazards on railway lines, such as cracks, wear, and looseness, significantly improving inspection efficiency and accuracy while reducing labor costs and risks.

[0003] Although using drones for inspection can improve detection efficiency and accuracy, drones are prone to crashing due to various unexpected factors during the inspection process. During the crash process, the drone's propellers are deployed outward and are in an optional state. During the crash process, it is easy to cause danger to pedestrians on the roadside. When the propellers rotate at high speed and touch the ground, they are likely to cause the propellers to crack and splash outward, causing serious damage to the drone and posing a danger to nearby pedestrians. Summary of the Invention

[0004] The purpose of the present invention is to provide a railway inspection drone data collection device to solve the problems existing in the background technology.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-5As shown, a railway inspection drone collection device of the present invention includes a body 1, a rotating frame 11 is provided on the lower side of the body 1, the rotating frame 11 is equipped with a camera 12, and fixed rods 12 are provided at the four corners of the body 1. The four fixed rods 12 are hinged with connecting rods 13 at one end away from the body 1, and the four connecting rods 13 are connected with flight rods 14 at one end away from the body 1. The four flight rods 14 are equipped with flight components 15, and limiting mechanisms are provided between the fixed rods 12 and the flight rods 14 and the connecting rods 13. Support rods 2 are provided on the left and right sides of the body 1, and the lower ends of the two support rods 2 are provided with stabilizing rods 21. The two support rods 2 are provided with vertical rods 22, and the lower ends of the two vertical rods 21 are equipped with cross rods 23. Connecting mechanisms are provided between the two cross rods 23 and the ends of the two flight rods 14 on the same side.

[0030] The staff can use the remote control to remotely control the flight components 15 assembled on the four flight rods 14 to start working. When the four flight components 15 start working, the body 1 starts to fly. At this time, the body 1 can be controlled by the remote control to patrol around the railway route and inspect the railway road conditions. The camera 12 can be used to shoot real-time images of the railway, and the video signal of the images can be transmitted to the remote control via a wireless communication route for remote viewing by the staff. In this way, the railway route can be inspected by the drone;

[0031] When the staff discovers that the drone has crashed through the remote control, they can remotely control the limit mechanism to cancel the operation through the remote control. This design can cancel the parallel connection between the fixed rod 12 and the connecting rod 12, and also cancel the parallel connection between the connecting rod 12 and the flight rod 14. At this time, the connecting rod 12 can rotate relative to the fixed rod 12, and the flight rod 14 can rotate relative to the connecting rod 12. At this time, the connecting mechanism automatically starts to work, pulling the flight rod 14, driving the flight rod 14 to rotate toward the lower side of the body 1. Until the flight rod 14 flips downward, the flight rod 14 drives the flight assembly 15 to move between the two support rods 2 on both sides. This design can quickly retract the four flight assemblies to the lower side of the body 1, and locate them between the two support rods 2 and the two stabilizer bars 21. This design ensures that after the body 1 falls to the ground, the body 1, support rods 2 and stabilizer bars 21 can contact the ground without causing the flight assembly 15 to contact the ground. This can protect the flight assembly 15 and prevent it from contacting the ground, thereby improving the protection effect of the body 1 and reducing the danger to nearby pedestrians.

[0032] The connecting mechanism includes two cavities 3, which are respectively arranged at the two ends of the two cross bars 23. Sliders 31 are slidingly sealed and assembled in the two cavities 3. The two sliders 31 are each provided with a first spring 32 on the side away from each other. The inner walls of the two cavities 3 on the side away from each other are each provided with a through hole 33 connected to the outside world. The two sliders 31 are each provided with a connecting line 34 on the end away from each other. One end of the two connecting lines 34 passes through the through hole 33 on the same side and is connected to the end of the flight rod 14.

[0033] When the fixing rod 12, the connecting rod 13 and the flight rod 14 are in a horizontal state, the first spring 32 is in a compressed state. When the limiting mechanism cancels the horizontal limiting connection between the fixing rod 12 and the connecting rod 13, and cancels the horizontal limiting connection between the connecting rod 13 and the flight rod 14, the first spring 32 quickly extends, and the two sliders 31 of the same cross bar 23 are quickly pushed closer to each other, so that the slider 31 pulls the connecting line 34 to move quickly, and the connecting line 34 pulls the end of the flight rod 14 to quickly flip inward toward the lower side of the body 1.

[0034] A fixing block 35 is provided on the middle side of the two support rods 2, and an airbag 36 is provided at the end of the fixing block 35. The airbag 36 is connected to a connecting hole 37 that passes through the support rod 2, the vertical rod 22 and the cross rod 23. The connecting hole 37 is connected to the two cavities 3 of the cross rod 23.

[0035] Since the slider 31 is slidingly and sealed in the cavity 3, when the two sliders 31 of the same cross bar 23 lean against each other, the two sliders 31 will squeeze the gas in the cavity 3, and inject the gas in the cavity 3 into the airbag 36 through the connecting hole 37, which will drive the airbag 36 to start expanding. With this design, when a crash occurs, the four flight rods 14 are folded inward and retracted into the lower side of the body 1, and the airbags 36 on the left and right sides of the two support rods 2 collide. This design can make the airbag 36 contact with the ground, further protecting the body 1, the flight component 15 and the camera 12, and preventing hard contact with the ground.

[0036] The two ends of the two cross bars 23 all point to the two flight rods 14 on the same side. Such a design can reduce the friction force on the connecting line 34 and protect the connecting line 34.

[0037] The limiting mechanism includes a stepped hole 4 provided in the fixing rod 12 and the connecting rod 13, a stabilizing block 41 is provided in each of the two stepped holes 4, a pulling assembly matching the stabilizing block 41 is provided in the stepped hole 4, the stabilizing block 41 is fixedly connected to a locking rod 42 extending out of the stepped hole 4, a second spring 421 is provided on the side of the stabilizing block 41 away from the locking rod 42, and the connecting rod 13 and the flight rod 14 are both provided with a locking hole 43 matching the locking rod 42.

[0038] During the flight of the aircraft 1, under the action of the extension of the second spring 421, the stabilizing block 41 drives the locking rod 42 to extend out of the step hole 4 and lock into the locking hole 43, so that the fixing rod 12 and the connecting rod 13 are horizontally limited and connected, and the connecting rod 13 and the flight rod 14 are horizontally limited and connected. When the flight rod 14 needs to be folded, the pulling assembly overcomes the elastic force of the second spring 421, drives the stabilizing block 41 into the step hole 4, and thereby drives the locking rod 42 to move out of the locking hole 43. At this time, the connecting rod 13 can be folded relative to the fixing rod 12, and the flight rod 14 can be folded relative to the connecting rod 13.

[0039] The pulling assembly includes an electromagnetic block 44 arranged in the step hole 4, and the stabilizing block 41 is an iron stabilizing block.

[0040] When power is supplied to the electromagnetic block 44 , the electromagnetic block 44 generates magnetism, which can adsorb the stabilizing block 41 and drive the stabilizing block 41 to retract into the step hole 4 .

[0041] A plurality of heat dissipation openings 45 are provided on the upper side of the body 1. The design of the plurality of heat dissipation openings 45 can dissipate heat and cool the interior of the body 1.

[0042] Both ends of the stabilizing bar 21 are provided with protective sleeves 46. The design of the protective sleeves 46 can protect the stabilizing bar 21.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
