Description

Technical Field

[0001] The present invention relates to the field of monitoring technology, and in particular to a vertical monitoring point installation device and an installation method for an unmanned aerial vehicle. Background Art

[0002] As a key link in tunnel construction and maintenance, tunnel vault settlement monitoring is generally implemented using the efficient and high-precision electronic leveling method. The core of this method is to achieve a stable and accurate measurement reference point at the tunnel vault segment position through a specific device.

[0003] However, in actual operation, especially when installing the hooks required for measurement on the vault segments, a series of challenges and difficulties are often encountered.

[0004] The traditional approach involves drilling holes in the vault area using an electric drill, followed by installing expansion bolts with hooks to fix the measuring device. This process is not only complicated and time-consuming, reducing work efficiency, but more importantly, it will inevitably cause physical damage to the tunnel segments, increasing the complexity and cost of structural maintenance. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention proposes a vertical monitoring point installation device and installation method for a UAV, which are used to solve the above technical problems.

The drone has a mounting groove at one end facing the mounting rod, and an internal thread is provided in the mounting groove. The mounting rod is connected to the mounting groove through threads.

[0014] Furthermore, the mounting assembly includes a mounting rod, the mounting rod is connected to the connecting rod, and the drone is provided with a mounting groove at one end facing the mounting rod, and the mounting groove is plugged into the mounting rod.

[0015] Furthermore, a groove is provided on one side of the mounting rod, a pressing column is installed in the groove, a spring is provided between the end of the pressing column and the inner wall of the groove, a through groove is provided on the inner wall of the mounting groove, and when the mounting rod and the mounting slot are plugged in, the end of the pressing column located outside the groove passes through the through groove and emerges from the outside of the drone.

[0016] Furthermore, two of the pressing columns and two of the springs are provided.

[0017] Furthermore, two of the grooves and two of the through slots are provided.

[0018] Furthermore, the drone is equipped with a camera and a laser rangefinder.

[0046] The drone 4 is equipped with a vertical (upward) camera (not shown in the figure) and a vertical (upward) laser rangefinder (not shown in the figure).

[0047] Specifically, through the coordinated arrangement of the connecting rod 1, the placement block 2, the placement groove, the mounting block 3, the reflective sticker and the drone 4, the measuring device can be vertically installed on the pipe segment of the tunnel vault by operating the drone 4, and can be adhesively installed by adhesive materials, thereby reducing the operation process and avoiding physical damage to the tunnel pipe segment as much as possible.

[0048] In some embodiments, a micro pressure sensor 5 is provided between the connecting rod 1 and the placement block 2 . The micro pressure sensor 5 is electrically connected to the drone 4 via a wire, and the sensor range is 0 to 5N.

[0049] Specifically, the micro pressure sensor 5 is used to determine whether the mounting block 3 is attached to the object to be measured.

[0050] In some embodiments, the end of the drone 4 is detachably connected to the connecting rod 1 via a mounting assembly.

[0051] Specifically, the drone 4 and the connecting rod 1 are installed through a mounting assembly, thereby facilitating disassembly and installation.

[0052] In some embodiments, the mounting assembly includes a mounting rod 61, the top end of the mounting rod 61 is fixedly connected to the bottom end of the connecting rod 1, an external thread 62 is provided on the outer side of the mounting rod 61, a mounting groove 63 is provided at one end of the drone 4 facing the mounting rod 61, an internal thread 64 is provided in the mounting groove 63, and the mounting rod 61 is connected to the mounting groove 63 by threads.

[0053] Specifically, by providing the mounting rod 61 , the mounting groove 63 , the external thread 62 and the internal thread 64 , it is convenient to disassemble and install the connecting rod 1 and the drone 4 , and at the same time has good stability.

[0055] like Figures 3 to 5 As shown in the figure, the difference from the first embodiment is that the mounting assembly includes a mounting rod 61, the top end of the mounting rod 61 is fixedly connected to the bottom end of the connecting rod 1, and a mounting groove 63 is opened at one end of the drone 4 facing the mounting rod 61, and the mounting groove 63 is plugged into the mounting rod 61.

[0056] Specifically, by plugging the mounting rod 61 into the mounting groove 63 , a more convenient installation and disassembly method can be provided.

[0057] In some embodiments, a groove 71 is provided on one side of the mounting rod 61, and a pressing column 72 is slidably installed in the groove 71. A spring 73 (compression spring) is provided between the end of the pressing column 72 and the inner wall of the groove 71. The two ends of the spring 73 are respectively fixedly connected to the end of the pressing column 72 and the inner wall of the groove 71. A through groove 74 is provided on the inner side wall of the mounting groove 63. When the mounting rod 61 and the mounting groove 63 are completely plugged in, the end of the pressing column 72 located outside the groove 71 passes through the through groove 74 and emerges from the outside of the drone 4.

[0065] Step S04: Use the UAV's own flight control system to control the UAV 4 to carry the connecting rod 1 to fly within 10m of the predetermined area;

[0066] Step S05: Use a vertical (upward) camera to search for the laser spot emitted by the total station at the survey station, and use the drone's own flight control system to drive the drone 4 close to the spot.

[0067] Step S06: Use a vertical (upward) laser rangefinder to feed back distance information in real time, and when the vertical distance between the drone 4 and the bottom (vault) of the structure is 500 mm, hover the drone 4, adjust the front direction of the mounting block 3 through the drone's own flight control system, so that its front directly faces the total station, turn on the lateral horizontal thrust engine, fine-tune the drone position to be directly below the light spot, and then slowly raise the drone to start installation.

[0068] Step S07, after the top of the mounting block 3 contacts the bottom of the structure, continue to push the drone 4 vertically upward. At this time, the micro pressure sensor begins to display the force size under pressure. When the micro pressure sensor displays that the positive pressure reaches 1.5N, keep the drone 4 in this control state for 15s.

[0069] Step S08, using the UAV's own flight control system to drive the UAV 4 vertically downward, the placement block 2 is separated from the mounting block 3, and the mounting block 3 is fixed at a predetermined position.

[0070] Step S09: Use the drone's own flight control system to drive the drone 4 to be recovered, completing the installation of the monitoring point.
