The device shell 1 is provided with a data acquisition mechanism 2, the two sides of the shell 1 are symmetrically provided with a landing protection mechanism 4, and the lower end of the shell 1 is detachably provided with a mounting connection mechanism 3 and a bottom support mechanism 5.

[0026] Specific, landing protection mechanism 4 includes symmetrically mounted on the two sides of the housing 1 rotating circular shaft 401, the rotating circular shaft 401 detachable installation has a streamlined cover 403, the housing 1 is provided for driving the rotating circular shaft 401 rotation micro motor 402, the streamlined cover 403 is provided with carbon dioxide cylinder 404 inside, the lower end of the streamlined cover 403 embedded with compressed air bag 405, the housing 1 is provided with an acceleration sensor 408, in the mode of hanging, normal flight, streamlined cover 403 will be in the open state, when the acceleration sensor 408 senses the rapid falling of the unmanned aerial vehicle, the streamlined cover 403 will rotate under the drive of micro motor 402, so as to shield the data acquisition mechanism 2, the inside of the streamlined cover 403 is provided with an installation groove, the installation groove is movably installed with a needle assembly 406, the surface of the streamlined cover 403 is provided with a water inlet channel 407, the water inlet channel 407 is communicated with the installation groove, after the equipment falls into the water, the water will enter the inside of the installation groove through the water inlet channel 407, the inside of the installation groove is filled with water soluble salt, the needle assembly 406 and the inner wall of the installation groove are fixedly installed with a driving spring, in the normal state, the driving spring is in the compressed state, when the water soluble salt melts after meeting water, the needle assembly 406 will contact with the carbon dioxide cylinder 404 under the action of the driving spring.

[0028] After the unmanned aerial vehicle falls into the water (sometimes it is necessary to use the unmanned aerial vehicle to transfer the collecting device to the top of the reservoir for data collection, if the unmanned aerial vehicle fails at this time, the collecting device will fall into the water, which is difficult to salvage), the water will flow into the inside of the installation groove through the water inlet channel 407, then the water soluble salt filled in the installation groove will dissolve quickly, and then the needle assembly 406 will pierce the carbon dioxide cylinder 404 under the action of the driving spring.

[0029] Next, the carbon dioxide gas will quickly enter the inside of the compressed air bag 405, so that the compressed air bag 405 is inflated quickly, and the buoyancy generated after the compressed air bag 405 is inflated will make the housing 1 and the unmanned aerial vehicle float on the water surface, so as to facilitate the staff to salvage in time.

[0030] The embodiment sets the landing protection mechanism 4. In the unmanned aerial vehicle mounting mode, the streamlined cover body 403 will automatically expand to both sides, which can effectively reduce the flight wind resistance and improve the endurance and stability of the unmanned aerial vehicle. When the acceleration sensor 408 detects that the unmanned aerial vehicle falls rapidly, the miniature motor 402 will quickly drive the cover body to rotate to the vertical state, forming a physical barrier to the data acquisition mechanism 2, so as to avoid direct damage to the precision elements when impacting.

[0032] According to the above content, in normal work, the laser radar 201 is responsible for obtaining high-precision three-dimensional point cloud data, and the high-pixel lens 202 and the wide-dynamic industrial color camera 203 synchronously acquire high-definition image information. At the same time, the heat dissipation module 205 continuously discharges the internal heat of the equipment through the heat dissipation air outlet 207, so as to ensure long-time stable operation.

[0033] When special environment data acquisition is required, the staff can quickly add multispectrum cameras and other function modules through the magnetic attraction module 208, so as to realize plug-and-play function expansion. The operation button 204 and the data interface 206 provide convenient human-computer interaction and data transmission channels, so that the whole system can adapt to the diversified needs from normal three-dimensional scanning to special environment monitoring.

[0034] This embodiment, through the installation and connection mechanism 3 and innovative modular integration design, achieves efficient acquisition and flexible expansion of multi-source data. It can not only complete conventional 3D scanning, but also quickly add professional modules such as multispectral data to meet the needs of special scenarios such as low-light environments. It not only solves the pain points of traditional equipment having single functions and inconvenient expansion, but also significantly improves the efficiency and adaptability of on-site data acquisition.

[0035] Example 3 To make on-site data acquisition more efficient and accurate, and to avoid the operational burden of large arm swings required by traditional equipment, based on the above embodiments, such as... Figures 1-10 As shown, this embodiment includes an installation connection mechanism 3. Specifically, the installation connection mechanism 3 includes an installation protrusion ring 301, which is fixedly installed at the bottom of the housing 1. A rubber flange 302 is provided on the outer periphery of the installation protrusion ring 301. An installation collar 303 is detachably installed on the outside of the installation protrusion ring 301. A hand handle 304 is movably installed at the lower end of the installation collar 303. The inside of the hand handle 304 is provided with a micro motor for driving the installation collar 303 to rotate. When the operator puts the installation collar 303 on the outside of the installation protrusion ring 301, the rubber flange 302 will engage with the installation collar 301. 03 Limits the movement to ensure that the housing 1 can rotate synchronously with the mounting collar 303. The handgrip 304 is equipped with a control knob 305 to control the rotation direction of the mounting collar 303. In handheld mode, the operator can use the control knob 305 to control the rotation of the mounting collar 303, thereby adjusting the direction of the housing 1. A connecting block 306 is detachably mounted on the mounting protrusion 301. The connecting block 306 is equipped with a conductive component 307. In mounted mode, the connecting block 306 will be fixedly connected to the drone. At this time, the housing 1 can fly with the drone to complete the data acquisition operation.

[0036] As can be seen from the above, when it is necessary to collect data on-site by hand, the staff will press the mounting collar 303 onto the outside of the mounting protrusion 301. At this time, the rubber flange 302 will limit the mounting collar 303.

[0037] During the subsequent data acquisition process, the staff can control the micro motor to rotate forward or backward by turning the control knob 305, thereby changing the facing angle of the housing 1. The staff only needs to keep the device stable and does not need to swing it significantly.

[0038] When remote data acquisition is required using a mounting method (mainly for environments that are difficult for people to reach, such as dangerous sites such as disasters and fires), the staff will screw the connecting block 306 into the mounting protrusion 301 to quickly fix the shell 1 to the drone. At this time, the drone will supply power to the acquisition device through the conductive component 307.

[0039] The embodiment can realize stable direction control, makes the on-site data collection work more efficient and accurate, avoids the operation burden of the traditional device that needs to swing the arm greatly, and is suitable for long-time operation scene.

The embodiment not only solves the problem of complicated mode switching of the traditional device, but also realizes the integration of power supply and data transmission, and is especially suitable for data collection work in dangerous areas such as fire scenes and reservoirs where personnel are difficult to reach, greatly expanding the application scenarios and functionality of the device.

When the collection device needs to be placed on the ground, the support rod 503 can be pulled out. The support rod 503 is arranged at equal intervals along the circumferential direction of the sliding sleeve ring 502, and the lower end of each support rod 503 is provided with an anti-skid ball sleeve 504. When the plurality of support rods 503 are simultaneously expanded outward, the collection device can be stably supported.

[0041] According to the above content, when the handheld operation is performed, the support rod 503 is completely accommodated in the interior of the handheld handle 304, and the overall compactness of the device is maintained. When the ground placement (sometimes on the upper end of the accident vehicle) is needed, the operator only needs to pull down the sliding sleeve ring 502 along the fixed circular rod 501, so as to simultaneously release the plurality of support rods 503 arranged at equal intervals in the circumferential direction.

[0042] Next, the support rod 503 is automatically expanded in a radial manner through the hinge structure, so that the anti-skid ball sleeve 504 at the distal end of the support rod 503 forms a multi-point contact with the ground, ensuring that the device can be stably supported under various terrains, and realizing rapid switching between the handheld mode and the ground placement mode.
