Technical Field

[0001] The utility model relates to the technical field of monitoring, and in particular to a vertical monitoring point installation device for an unmanned aerial vehicle. Background Art

[0002] Tunnel vault settlement monitoring, a critical component of tunnel construction and maintenance, is commonly implemented using the efficient and highly accurate electronic leveling method. The core of this method is the use of specialized equipment to establish a stable and precise measurement reference point at the tunnel vault segment location.

[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 method involves drilling holes in the vault area with an electric drill, followed by installing expansion bolts with hooks to secure the measuring devices. This process is not only complex and time-consuming, reducing work efficiency, but more importantly, it inevitably causes physical damage to the tunnel segments, increasing the complexity and cost of structural maintenance.

[0028] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figures 1-2 As shown in the figure, a vertical monitoring point installation device for a drone of the present invention includes a connecting rod 1, the connecting rod 1 has an outer diameter of 16 mm, an inner diameter of 14 mm, and a length of 270 mm, and is made of carbon fiber material; a placement block 2, which is arranged at the top of the connecting rod 1, and a placement groove is opened at the top of the placement block 2, and the placement block 2 is made of stainless steel; a mounting block 3, the bottom end of which is placed in the placement groove, the top of the mounting block 3 protrudes from the placement groove, and a reflective sticker (a self-adhesive reflective sticker for surveying and measurement) is pasted on the outer surface of the mounting block 3. The reflective sticker is not shown in this embodiment, and the outer surface of the top of the mounting block 3 is coated with an adhesive material (epoxy resin), which can be used for bonding with the vault pipe segment. The length, width and height of the mounting block 3 are all 40 mm and are made of lightweight material; and a drone 4 (the drone is a four-rotor drone), which is located at the end of the connecting rod 1 away from the placement block 2, and the middle part of the top of the drone 4 is connected to the bottom end of the connecting rod 1;

[0031] 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).

[0032] 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 using adhesive materials, thereby reducing the operation process and avoiding physical damage to the tunnel pipe segment as much as possible.

[0033] 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.

[0034] Specifically, the micro pressure sensor 5 is used to determine whether the mounting block 3 is attached to the object to be measured.

[0035] In some embodiments, the end of the drone 4 is detachably connected to the connecting rod 1 via a mounting assembly.

[0036] Specifically, the drone 4 and the connecting rod 1 are installed through a mounting assembly, thereby facilitating disassembly and installation.

[0037] 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, and 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 and the mounting groove 63 are connected by threads.

[0038] Specifically, by providing the mounting rod 61 , the mounting groove 63 , the external thread 62 and the internal thread 64 , the disassembly and assembly between the connecting rod 1 and the drone 4 are facilitated while having good stability.

[0039] Example 2:

[0040] like Figures 3-5 As shown in the figure, the difference from Example 1 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 the drone 4 is provided with a mounting groove 63 at one end facing the mounting rod 61, and the mounting groove 63 is plugged into the mounting rod 61.

[0041] Specifically, by plugging the mounting rod 61 into the mounting slot 63 , a more convenient installation and disassembly method can be provided.

[0042] 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 fixedly connected to the end of the pressing column 72 and the inner wall of the groove 71 respectively. 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 fully 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.

[0043] When the cam 72 is in the closed position, the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, so that the cam 72 is locked.

[0044] In some embodiments, there are two pressing posts 72 and two springs 73 , and they are symmetrically arranged. There are also two grooves 71 and two through slots 74 , and they are symmetrically arranged.

[0045] The vertical monitoring point installation device of a drone of the present application can also bury monitoring points in the web of a bridge.

[0046] The method of using the utility model is as follows:

[0047] Bury monitoring points in the tunnel vault:

[0048] Step 1: Install the connecting rod 1 on the drone 4.

[0049] Step 2: Apply 15g of epoxy resin evenly on the top of the mounting block 3.

[0050] Step 3: Place the bottom end of the mounting block 3 in the placement groove of the placement block 2.

[0051] Step 4: Use the drone's own flight control system to control the drone 4 carrying the connecting rod 1 to fly within 10m of the predetermined area.

[0052] Step 5: 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.

[0053] Step 6: Use the vertical (upward) laser rangefinder to feedback the distance information in real time, and when the vertical distance between the UAV 4 and the bottom (vault) of the structure is 500 mm, hover the UAV 4, adjust the front direction of the mounting block 3 through the UAV's own flight control system so that its front directly faces the total station, and at the same time turn on the side horizontal thrust engine, fine-tune the UAV position to be directly below the light spot, and then slowly raise the UAV to start burying.

[0054] Step 7. 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 show the force. When the micro pressure sensor shows that the positive pressure reaches 1.5N, keep the drone 4 in this control state for 15s.

[0055] Step 8: Use the drone's own flight control system to drive the drone 4 vertically downward, separate the placement block 2 from the mounting block 3, and fix the mounting block 3 at the predetermined position.

[0056] Step 9: Use the drone's own flight control system to drive the drone 4 to recover and complete the monitoring point installation.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
