[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1, as Figure 1-4 As shown, the utility model provides a bridge inspection drone based on 3D modeling, comprising: a drone body 1, a monitoring device 101 fixedly installed on the top of the drone body 1, and also comprising: a plurality of fixing seats 2, fixedly installed in a circular array on the outer surface of the drone body 1, a plurality of fixing seats 2 are threadedly embedded with connecting rods 201 on one side, a plurality of protective frames 203 are provided on the outer surface of the drone body 1 in a circular array, a connecting seat 202 is fixedly installed on the inner side of the plurality of protective frames 203, and one end of the plurality of connecting rods 201 is movably embedded in the interior of the plurality of connecting seats 202.
[0026] Further, such as Figure 1-4 As shown, a limiting groove 204 is provided on one side of the multiple protective frames 203, and a limiting block 205 is fixedly installed on the other side of the multiple protective frames 203. The outer surfaces of the multiple limiting blocks 205 are movably embedded in the interior of the multiple limiting grooves 204. Through the above-mentioned arrangement, when the limiting block 205 is inserted into the interior of the limiting groove 204, the protective frame 203 can be limited so that the protective frame 203 cannot rotate.
[0027] Further, such as Figure 1-4As shown, a slide rail 3 is fixedly installed at the center of the bottom of the drone body 1, and a rack 301 is movably embedded in the inner wall of the slide rail 3. Two fixed blocks 304 are symmetrically fixedly installed on the bottom of the slide rail 3. A rotating rod 305 is movably embedded on the opposite side of the two fixed blocks 304 near the bottom. A gear 306 is fixedly sleeved on the outer surface of the rotating rod 305. The teeth of the gear 306 are engaged with the teeth of the rack 301. Under the action of the meshing of the rack 301 and the gear 306, when the rack 301 slides left and right inside the slide rail 3, it can drive the gear 306 to rotate clockwise or counterclockwise.
[0028] Further, such as Figure 1-4 As shown, a fixing plate 302 is fixedly installed at the bottom of the eccentric part of the drone body 1, and an electric telescopic rod 303 is fixedly installed on one side of the fixing plate 302. One end of the electric telescopic rod 303 is fixedly installed on one side of the rack 301. The electric telescopic rod 303 is started by the controller to extend or retract it, so that it drives the rack 301 to slide back and forth inside the slide rail 3.
[0029] Further, such as Figure 1-4 As shown, bracket 1 307 is fixedly mounted on both ends of the rotating rod 305, and monitoring device 2 308 is fixedly installed on the opposite side of the two brackets 1 307. Through the above arrangement, when the rotating rod 305 rotates, it can drive bracket 1 307 and monitoring device 2 308 to rotate, thereby increasing the monitoring range of monitoring device 2 308.
[0030] Further, such as Figure 1-4 As shown, the two brackets 1 307 are fixedly installed with fixing bars 4 on the bottom away from the fixed block 304, and the two fixing bars 4 are fixedly installed with round rods 1 401 on the opposite sides close to the bottom. The outer surface of the round rod 1 401 is symmetrically and movably sleeved with two brackets 2 402, and the two brackets 2 402 are fixedly installed with lighting lamps 403 on the opposite sides away from the round rod 1 401. Through the above arrangement, the brackets 2 402 can be rotated upward or downward around the outer surface of the round rod 1 401 at an appropriate angle, so that the angle of the lighting lamps 403 can be appropriately adjusted.
[0031] Further, such as Figure 1-4 As shown, a round rod 2 404 is fixedly installed on the opposite side of the two brackets 402 away from the irradiation lamp 403, and a round rod 3 405 is fixedly installed on the opposite side of the two brackets 1 307 away from the monitoring device 2 308. The outer surface of the round rod 3 405 is movably sleeved with an electric telescopic rod 2 406, and one end of the electric telescopic rod 2 406 is movably sleeved on the outer surface of the round rod 2 404. The electric telescopic rod 2 406 is activated by the controller to extend or contract, applying a force to the round rod 2 404 to make the bracket 2 402 rotate upward or downward around the outer surface of the round rod 1 401.
[0032] Working principle: During use, when the drone body 1 needs to be used to inspect the bridge, first rotate the connecting rod 201 by hand so that the connecting rod 201 is installed on the top of the fixing seat 2. The connecting rod 201 can be rotated inside the connecting seat 202, and the limit block 205 is inserted into the inside of the limit groove 204 to limit the protective frame 203 so that the protective frame 203 cannot rotate, so that multiple protective frames 203 surround the drone body 1 and protect it. In this way, during the inspection of the bridge, the drone body 1 can avoid the wings of the drone body 1 from directly colliding with the bridge, and avoid damage to the drone body 1, thereby ensuring the smooth progress of the bridge inspection work. When the drone body 1 inspects the bridge, the bridge above the drone body 1 can be monitored through the monitoring device 101, and then the electric telescopic rod 303 can be controlled by the controller to start and extend it. Or contract, so that it drives the rack 301 to slide back and forth inside the slide rail 3, and then under the action of the meshing of the rack 301 and the gear 306, the gear 306 can be driven to rotate clockwise or counterclockwise, and the rotating rod 305, the bracket 1 307 and the monitoring device 2 308 can be synchronously driven to rotate clockwise or counterclockwise, and the monitoring angle of the monitoring device 2 308 can be properly adjusted to improve the monitoring range, and the electric telescopic rod 2 406 is controlled by the controller to start, so that it can be extended or contracted, and a force is applied to the round rod 2 404 to make the bracket 2 402 rotate upward or downward around the outer surface of the round rod 1 401, so that the angle of the illumination lamp 403 can be properly adjusted, so that the area illuminated by the illumination lamp 403 can be adjusted according to the distance of the monitoring position of the monitoring device 2 308, so that the dark area of the bridge can be monitored more clearly, and the problems of the bridge can be more easily detected through 3D modeling technology.
