Technical Field

[0001] The present invention relates to a drone survey device for steel structure buildings, belonging to the technical field of drone survey devices for steel structure buildings. Background Art

[0002] Generally, a steel structure building is composed of a steel frame coated with a functional coating. The coating needs to be regularly maintained and applied to ensure the safety of the overall steel frame. Moreover, if the thickness of the coating is relatively thin, the functional effect is relatively weak, and it is easy to damage the steel at the bottom.

[0003] When surveying the coating film thickness of high-rise steel structures, the existing technology is to assist workers in high-altitude operation and measurement through an external lifting platform. However, in some environments, the external lifting platform cannot be used, and a hanging basket needs to be used. Both of the above two auxiliary devices require workers to conduct high-altitude survey and measurement operations, which are time-consuming and laborious, and have high risks.

A plurality of stretching springs are connected to the peripheral edge of the right side surface of the circular stretching plate in an annular array, and the other ends of the stretching springs extend and are fixedly connected to the peripheral circle of the surface of the magnetic suction seat group in an annular array.

[0013] Further improved, the reset fiber guiding group includes a winder main body, a fiber guiding steel wire rope is wound on the winder main body, and the other end of the fiber guiding steel wire rope is connected to a tension sensor, and the tension sensor is fixedly installed in the middle of the bottom of the tension sensor sleeve groove.

Among them, the universal angle self-adaptive adjustment seat composed of the magnetic suction seat group, the universal ball seat, and the external tensile force buffer assembly can assist the surveying head mechanism to make self-adaptive angle fine-tuning when it abuts against the surface of the steel structure, making it easier for the surveying head mechanism to horizontally abut against the surface of the steel structure. Moreover, the universal angle self-adaptive adjustment seat can also weaken the oblique stress and external tensile stress when the drone body is shaken by the wind, preventing the surveying head mechanism from being electromagnetically adsorbed and detached due to the externally transmitted tensile stress. The surveying head mechanism has the function of electromagnetically adsorbing the surface of the steel structure and simulates the manual light sticking of workers during surveying, making the light sticking force of the surveying instrument body controllable. The reset fiber guiding group plays a role in fiber guiding connection after canceling the detached state of the electromagnetic connection between the magnetic suction seat group and the fiber guiding electromagnetic seat group, facilitating the subsequent rapid alignment operation when the drone body makes a reset connection. In addition, the fiber guiding steel wire rope on the reset fiber guiding group can be adjusted to a soft state, which can provide an external tensile buffer distance again between the drone body and the surveying head mechanism, so that when the drone body has a large shaking displacement caused by strong wind, the surveying head mechanism can also be prevented from being transmitted to the external tensile stress. The auxiliary cooperation of the above functions enables the surveying operation of the drone surveying device to adapt to various wind weather conditions, improves the surveying effect, effectively replaces manual high-altitude operations, eliminates high-altitude operation risks, and saves time and effort.

[0046] Working principle:

[0047] During use, the surveying device 2 is integrally mounted on the drone body 1 by engaging the base 11 with the sleeve of the sleeve slider 213, and the electrical signal is connected. The drone body 1 is then operated to fly to a high steel structure, and then the surface of the steel structure is checked to see whether it is horizontal or inclined. The rotator 212 on the rotating frame group 21 drives the gantry 211 to adjust the angle. The maximum adjustment angle of the rotating frame group 21 is 360°. The drone body 1 is then moved toward the direction of the steel structure to be surveyed, so that the first electromagnetic suction cups 243 on the surveying head mechanism 24 are offset against the surface of the steel structure and electromagnetically connected and fixed. During the offset process, it is difficult for the drone body 1 to maintain a completely aligned state, and it will be offset at a slightly tilted angle. However, the universal joint composed of the magnetic seat group 231, the universal ball seat 232, and the external tension buffer component 233 The angle adaptive adjustment seat and the universal angle adaptive adjustment seat can cooperate to assist in realizing the adaptive adjustment level of the survey head mechanism 24 and the steel structure surface. After completing the electromagnetic adsorption of the survey head mechanism 24, the drone body 1 first performs a hovering operation, and then the telescope 2422 is extended. Because the left side of the survey instrument body 2425 is retracted to the initial setting of 0.2mm on the left side of the pressing disk 24242, when the telescope 2422 is extended to drive the pressing disk 24242 to press the steel structure surface, when the pressure sensor 2423 senses the limit pressure value, it will cause the pressing disk 24242 to deform and align vertically with the left side of the survey instrument body 2425, so that the left side of the survey instrument body 2425 is lightly attached to the steel structure surface for surveying operations, similar to the model defense staff manually operating the survey instrument body 2425 to lightly attach to the steel structure surface for surveying operations.

[0048] In addition, when surveying in breeze weather, after the drone body 1 hovers, the breeze causes the drone body 1 to shake and displace at a small interval. Through the automatic universal swing adjustment function of the universal angle adaptive adjustment seat composed of the magnetic seat group 231, the universal ball seat 232, and the external tension buffer assembly 233, and the unilateral buffering stretching of the unilateral stretching structure composed of the circular fixing plate 2331, the circular stretching plate 2332, multiple stretching slides 2333 and multiple first springs 2334, the lateral stress and oblique stress transmitted to the survey head mechanism 24 when the drone body 1 shakes can be reduced to the greatest extent, so that the electromagnetic adsorption of the survey head mechanism 24 to the structural surface will not be pulled away.

[0049] In addition, when surveying in windy weather, after the drone body 1 hovers, the strong wind will cause a large shaking displacement interval on the drone body 1, and the shaking displacement interval will be greater than the maximum buffer stretching interval of the unilateral tensile structure, so the outward tensile stress transmitted to the survey head mechanism 24 will be very strong, so that the electromagnetic adsorption of the survey head mechanism 24 is at risk of being pulled off. At this time, the fiber-guided steel wire rope 2342 can be released through the reel body 2341, and the electromagnetic connection between the second electromagnetic suction cup 223 and the circular magnetic block 2312 is canceled synchronously, and the drone body 1 is displaced in the opposite direction of the steel structure, so that the fiber-guided electromagnetic seat group 22 and the magnetic seat group 231 are completely separated. When the tension sensor 2343 senses no tension value, the fiber-guided steel wire rope 2342 is in a loose state, and the spring power supply coil 25 is in a stretched and extended state. Refer to the attached Figure 1 、 2 In this state, when strong winds cause the UAV body 1 to shake and displace to a large extent, the loose state of the fiber-pulling wire rope 2342 provides a large external pulling buffer distance, so that the UAV body 1 will not transmit outward pulling stress to the survey head mechanism 24.

[0050] When the survey is completed, the reel body 2341 reels the fiber wire rope 2342, which will move the drone body 1 toward the magnetic seat group 231, and the drone body 1 will also make a coordinated displacement. When the tension sensor 2343 senses a strong pulling force, it can be determined that the circular magnetic block 2312 and the second electromagnetic suction cup 223 are in a state of being offset and electromagnetically connected. The fiber pulling force after the reset fiber group 234 is fully reeled can strengthen the electromagnetic connection between the circular magnetic block 2312 and the second electromagnetic suction cup 223. Finally, each first electromagnetic suction cup 243 cancels the electromagnetic adsorption, and the survey telescopic head group 242 synchronously retracts and resets, the drone body 1 flies away, and the survey operation is completed.
