[0035] The scraper 216 is configured to be sawtooth-like for better scraping of the wall.

[0036] It also includes an indicator sign 2021; two indicator signs 2021 are connected to the driving mechanism.

[0037] It also includes a spring rod 2022; two spring rods 2022 are connected to the driving mechanism, and another four spring rods 2022 are connected to the left part of the connecting frame 2.

[0038] The driving mechanism includes a slide bar 202, a gear bar 203, a motor II 204 and a spur gear 205; two slide bars 202 are slidably connected to the base frame 201; each slide bar 202 is fixedly connected to a sign 2021; each slide bar 202 is slidably connected to a spring bar 2022; each slide bar 202 is fixedly connected to a gear bar 203; two motors II 204 are fixedly connected to the upper part of the base frame 201; a spur gear 205 is fixedly connected to the output shaft of each motor II 204; each spur gear 205 is meshed with a gear bar 203.

[0039] When processing and inspecting the exterior wall of a building: the mounting plate 1 is pre-installed on the drone by bolts, and the movable end of the film 209 is pulled to fix the movable end of the film 209 on the rotating roller 211 below, and then the drone is controlled by a professional, so that the intelligent inspection device for engineering buildings based on drone mounting is mounted on the drone. Since the existing drone carries an infrared thermal camera for overall inspection of the building, the crack is determined by the temperature difference at the crack, and a large amount of data is processed later to issue an exterior wall crack inspection report, thereby realizing the inspection of the building, making the measurement more convenient. However, during the inspection process, when the drone flies close to the wall, when cleaning the wall skin and impurities such as sand and gravel on the wall surface, it is easy to cause impurities to fall, which then causes the risk of falling objects from high altitude, seriously threatening the safety of pedestrians, and the peeling wall skin of the wall will change the thermal radiation characteristics of the wall surface (for example, the peeling wall skin may form hot spots or cold spots, which may be mistaken for cracks), thereby interfering with the accuracy of the infrared thermal image, thereby affecting the shooting quality of the exterior thermal camera and the accuracy of crack identification.

[0040] In order to solve the above problem, the drone is manually controlled to fly to the area to be measured, so that all the spring rods 2022 on the connecting frame 2 are pressed against the wall, and the information on the two signboards 2021 is used to inform the personnel in the building that the inspection operation is being carried out, and then the two motors II 204 are controlled to start operation, and the output shafts of the two motors II 204 rotate to drive a spur gear 205 to rotate, and the two spur gears 205 rotate to drive a gear rod 203 to move left, and the two gear rods 203 move to drive a slide bar 202 to move, and the two slide bars 202 move to drive the connecting rod 208 to move left, thereby driving all the connected parts to move, thereby making the two rotating rollers 211 move towards the wall, and making the two spring rods 202 press against the wall, and at the same time, the two spring rods 202 are used for buffering to avoid a violent collision between the two rotating rollers 211 and the wall when they come into contact;

[0041] Furthermore, since the rotating roller 211 at the bottom protrudes to the left from the rotating roller 211 at the top, when the two rotating rollers 211 move toward the wall, the rotating roller 211 at the bottom can move against the wall and twist the corresponding elastic member 213, and a gap is reserved between the rotating roller 211 at the top and the wall, so that the scraper 216 can rotate to scrape the wall, and the rotating roller 211 at the bottom moves against the wall, so that the flight stability of the drone can be improved, and at the same time, the film 209 on the rotating roller 211 at the bottom presses against the wall, and then the motor I 212 on the fixing plate II 214 is controlled to start, and the output shaft of the motor I 212 rotates to drive the rotating roller 211 at the top to rotate. The upper rotating roller 211 rotates to drive the water absorbing member 215 and the scraper 216 to rotate synchronously, and then the water stains on the wall surface are absorbed by the water absorbing member 215, and the scraper 216 rotates to scrape the wall skin that has fallen off the wall surface, and controls the motor I 212 below to start, and the output shaft of the motor I 212 below rotates to drive the lower rotating roller 211 to rotate, and then pulls the movable end of the film 209 to move, so that the film 209 adheres to the scraped wall skin, thereby achieving the absorption of water stains on the wall surface, and scraping off the wall skin that has fallen off the wall surface, and at the same time, the scraped wall skin is adhered and collected, thereby reducing the interference caused by water stains and wall skin to the infrared camera 207 during detection.

[0042] Then, the infrared camera 207 is controlled to start operating to detect cracks in the wall, thereby realizing the detection of cracks in the wall, improving the shooting quality of the infrared camera 207 and the accuracy of crack recognition, and being able to control all electric sliders 21 to start and drive the base frame 201 to move according to the range of the required detection area, thereby driving all connected components to move, so that the two rotating rollers 211 move synchronously, and in the same manner as described above, the water stains on the wall surface of the area to be measured are sucked away by the rotation of the water absorbing member 215, and at the same time, the wall skin that has fallen off the wall surface of the area to be measured is scraped away by the rotation of the scraper 216, and the scraped wall skin is adhered and collected by the film 209.

[0043] Embodiment 2:

[0044] Based on the first embodiment, Figure 1 and Figure 6-Figure 9As shown, it also includes a collection system; the base frame 201 is connected to the collection system; the collection system includes a connecting plate 302, a hook I 303, a collection bag 304, an elastic strip 3043, an electric winding machine 305, a four-claw rope 306, a cross bar 307, an electric actuator 308, a bracket 309, a top plate 310 and a hook II 311; two connecting plates 302 are fixedly connected to the lower part of the base frame 201; each connecting plate 302 is fixedly connected to a hook I 303; all the hooks I 303 are detachably connected to a collection bag 304, and the four corners of the upper rectangle of the collection bag 304 are respectively provided with a fixing plate 3041 and a hanging ear 3042; the front of the collection bag 304 and the rear of the collection bag 304 are respectively fixedly connected to a plurality of elastic strips 3043; the base frame 20 An electric winder 305 is installed on the lower surface; a four-claw rope 306 is wound on the electric winder 305; the four-claw rope 306 is connected to the collection bag 304 through all the hanging ears 3042; each slide bar 202 is fixedly connected to a cross bar 307; each cross bar 307 is rotatably connected to an electric actuator 308, the electric actuator 308 is an electric push rod, and a torsion spring I is connected between each cross bar 307 and the electric actuator 308; the telescopic part of each electric actuator 308 is rotatably connected to a bracket 309, and a torsion spring II is connected between the telescopic part of each electric actuator 308 and the bracket 309; all the brackets 309 are commonly fixed to a top plate 310; two hooks II 311 are fixed to the top plate 310.

[0045] The hook Ⅰ303 is provided with an arc section 3031 , and the arc section 3031 is set to be made of rubber material, so that the fixing piece 3041 on the collecting bag 304 can fall off from the hook Ⅰ303 .

[0046] The bottom of the bottom frame 201 is fixedly connected with the shielding plate 301 .

[0047] It also includes a protrusion 312 ; two hooks II 311 are on the top plate 310 , and each protrusion 312 is located below a corresponding hook II 311 .

[0048] When collecting large-volume wall skins: before the drone takes off, the collection bag 304 is mounted on the connecting plate 302 and the top plate 310, that is, the two fixing pieces 3041 on the right side of the collection bag 304 are each mounted on a hook I 303, and the two fixing pieces 3041 on the left side of the collection bag 304 are each mounted on a hook II 311, and then the four hanging ears 3042 on the collection bag 304 are connected to the four-claw rope 306. When the drone takes off and falls off the ground, the collection bag 304 is stretched open by the elastic force generated by the elastic strip 3043 and becomes a net bag shape, such as Figure 6As shown, when the scraper 216 is used to rotate and scrape the wall skin on the wall surface, it is easy to cause the wall skin to fall off in large areas, and the film 209 cannot quickly adhere to and collect all the fallen wall skin, which can easily cause the wall skin to fall from a high place, endangering pedestrians on the ground;

[0049] When the two slide bars 202 move to the left, the two slide bars 202 move and each drive a cross bar 307 to move, the two cross bars 307 move and each drive an electric actuator 308 to move, thereby driving all connected parts to move, thereby driving the left part of the collecting bag 304 to move, and when the rotating roller 211 below presses against the wall to the left, the two electric actuators 308 are controlled to start and each drive a bracket 309 to move to the left, and the two brackets 309 move and jointly drive the top plate 310 to move, and the top plate 310 moves and drives the two hooks II 311 and the two protrusions 312 to move to the left at the same time, and after the two protrusions 312 move and press against the wall, the electric actuator 308 is controlled to start and each drive a bracket 309 to continue to move to the left, at this time, because the two protrusions 312 have pressed against the wall, the top plate 310 and the two The bracket 309 rotates and twists the torsion spring II between the telescopic part of the electric actuator 308 and the bracket 309, so that the upper edge of the top plate 310 is pressed against the wall. At the same time, the two hooks II 311 are pressed against the wall and deformed by the obstruction of the wall, so that the upper parts of the two hooks II 311 are pressed against the top plate 310, and then the two fixing plates 3041 on the left side of the collecting bag 304 are buckled, and the fallen wall skin can be guided through the top plate 310, so that the fallen wall skin flows into the collecting bag 304, so that when a large area of ​​wall skin falls off and the film 209 cannot be quickly adhered and collected, the wall skin falls down into the collecting bag 304 and is collected by the collecting bag 304, thereby reducing the possibility of wall skin falling from a height and endangering pedestrians on the ground, and effectively improving the safety of the detection operation.

[0050] However, when large pieces of wall skin fall off, some of the wall skin will fall into the space formed by the two rotating rollers 211 and the wall, and the film 209 on the lower rotating roller 211 is difficult to adhere and collect the large pieces of wall skin, so that the large pieces of wall skin will stay on the lower rotating roller 211 and be carried by the lower rotating roller 211. After the detection is completed, the output shafts of the two motors II 204 are controlled to rotate, each driving a spur gear 205 to rotate in the opposite direction, thereby driving all the connected parts to move to the right and reset, so that the two rotating rollers 211 are away from the wall. At this time, the wall skin carried by the lower rotating roller 211 The skin will fall down, and at the same time, the two electric actuators 308 are controlled to start and drive each bracket 309 to continue to move to the left, so that when the two rotating rollers 211 move away from the wall to reset, the top plate 310 still presses against the wall, so that the collecting bag 304 can continue to collect the wall skin, so that the wall skin that falls between the two rotating rollers 211 and the wall falls into the collecting bag 304, and when a large area of ​​wall skin falls off and hollows appear on the wall, the spray gun 313 is controlled to operate to mark the wall where the hollows appear, and then the wall where the hollows appear is processed manually.

[0051] After the wall skin is collected, the two electric actuators 308 are controlled to start and drive each bracket 309 to move rightward and reset, thereby driving all the connected components to move, so that the top plate 310 is away from the wall. At this time, the collection bag 304 is loaded with wall skin. In order to reduce the wall skin from floating around during the transfer process, the electric reel 305 is controlled to start and operate the reeling four-claw rope 306, and then the four hanging ears 3042 of the collection bag 304 are pulled by the four-claw rope 306. Since the arc section 3031 on the hook Ⅰ 303 is made of rubber, when the collection bag 304 is contracted, the two fixing pieces 3041 on the right will be pulled from the corresponding hook Ⅰ 30 3, and at the same time, the two electric actuators 308 are controlled to start and shrink, thereby driving each bracket 309 to move, and when the two electric actuators 308 shrink, the collection bag 304 will be affected by the gravity of the wall skin, causing the electric actuator 308 to rotate, thereby twisting the torsion spring I between the cross bar 307 and the electric actuator 308, so that the bag opening of the collection bag 304 shrinks and the collection bag 304 moves upward as a whole, so that the bag opening of the collection bag 304 is close to the bottom frame 201, and the bag opening of the collection bag 304 is shielded by the mask plate 301, thereby reducing the phenomenon of the wall skin floating around during the transfer process.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
