[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] An embodiment of the present application discloses a drone equipped with an earthwork measurement device.

[0035] Reference Figure 1 A UAV equipped with an earthwork measurement device comprises a UAV body 1, a base 2 is fixedly connected to the bottom of the UAV body 1, a T-shaped slot is provided at the bottom of the base 2, a T-shaped block 3 is slidably connected inside the T-shaped slot, a measuring probe 4 is fixedly connected to the bottom of the T-shaped block 3, a cleaning component 5 is installed at one end of the measuring probe 4, a clamping component 6 is installed on the top of the base 2, and all electrical appliances are electrically connected to an external controller.

[0036] When in use, first insert the T-block 3 into the T-slot at the bottom of the base 2. Through the cooperation between the T-block 3 and the T-slot, the measuring probe 4 can be quickly installed on the drone body 1. Then start the clamping assembly 6 to clamp the side and bottom of the measuring probe 4 to stabilize it, thereby improving the stability of the measuring probe 4 during the flight of the drone body 1 and avoiding it from falling off. When the measuring probe 4 is stable, the drone body 1 can be turned on for flight detection. During the detection process, dust floating in the air will be adsorbed on the lens of the measuring probe 4. At this time, the cleaning assembly 5 can be started to clean the lens back and forth, so that the lens on the measuring probe 4 can always remain clear, effectively improving the efficiency of earthwork detection.

[0037] Reference Figure 1 and Figure 4 Sliding grooves 31 are symmetrically provided on both sides of the T-shaped block 3, and a block 32 is slidably connected inside the sliding groove 31. A spring 33 is fixedly connected inside the sliding groove 31, and one end of the spring 33 is fixedly connected to one end of the block 32. One end of the block 32 is arc-shaped. Slots 34 are symmetrically provided on both sides of the T-shaped groove, and the shape and size of the slots 34 are consistent with the arc-shaped end of the block 32.

[0038] When in use, first push the T-shaped block 3 into the T-shaped groove. At this time, the inner wall of the T-shaped groove will squeeze the block 32 into the interior of the sliding groove 31, so that the T-shaped block 3 can better enter the T-shaped groove. When the T-shaped block 3 is fully inserted, the sliding groove 31 will be parallel to the card slots 34 on both sides. At this time, after the block 32 loses its extrusion, the spring 1 33 will rebound and push the block 32 into the interior of the card slot 34. Through the mutual cooperation between the block 32 and the card slot 34, the measurement probe 4 and the drone body 1 can be quickly installed and removed, which effectively improves the practicability of the device.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The cleaning assembly 5 includes a fixed frame 51 fixedly connected to one end of the measuring probe 4, a screw rod 52 is rotatably connected inside the fixed frame 51, a motor 53 is fixedly connected to one side of the fixed frame 51, an output end of the motor 53 is fixedly connected to one end of the screw rod 52, a movable plate 55 is threadedly connected to the screw rod 52, a guide rod 54 is fixedly connected inside the fixed frame 51, one end of the movable plate 55 is slidably connected to the guide rod 54, a cleaning brush 56 is clamped at the bottom of the movable plate 55, and adjusting grooves 57 are symmetrically opened on both sides of the bottom of the movable plate 55, a pressing block 58 is slidably connected inside the adjusting groove 57, a spring 2 59 is fixedly connected inside the adjusting groove 57, one end of the spring 2 59 is fixedly connected to one end of the pressing block 58, a limiting block 510 is fixedly connected to the bottom of the pressing block 58, a groove is symmetrically opened on the top of the cleaning brush 56, and the limiting block 510 is slidably connected in the groove.

[0040] When in use, first start the motor 53 to drive the screw 52 to rotate. When the screw 52 rotates, the moving plate 55 will move back and forth on the screw 52 along with the guide of the guide rod 54. The reciprocating movement of the moving plate 55 will drive the cleaning brush 56 at the bottom to move back and forth to clean the lens of the measuring probe 4, so that the lens can always remain clear, reducing the blur of the lens that affects the detection result;

[0041] Secondly, when the cleaning brush 56 needs to be replaced after being used for a long time, the pressing blocks 58 on both sides can be manually pressed to move in the adjustment groove 57 to squeeze the spring 2 59 to contract. When the pressing block 58 moves, it will drive the limit block 510 to move together, so that the limit block 510 is pulled out of the groove, thereby releasing the connection between the movable plate 55 and the cleaning brush 56 to replace the cleaning brush 56. After the replacement is completed, the limit block 510 is reinserted into the groove. At this time, the pressing block 58 is released. According to the rebound of the spring 2 59, the pressing block 58 can always be pushed forward, so that the limit block 510 can always be in the groove, thereby limiting and stabilizing the cleaning brush 56.

[0042] Reference Figure 1 and Figure 5 The clamping assembly 6 includes an electric telescopic rod 61 symmetrically fixedly connected to the top of the base 2, the output ends of the electric telescopic rod 61 are fixedly connected to a C-shaped plate 62, the bottom of the C-shaped plate 62 is fixedly connected to an L-shaped plate 63, and the inner wall of the L-shaped plate 63 is fixedly connected to an anti-slip pad 64.

[0043] When in use, first start the electric telescopic rod 61 to drive the two C-shaped plates 62 to retract, so as to drive the two L-shaped plates 63 to gradually fit with the side and bottom surfaces of the measuring probe 4. The two L-shaped plates 63 can clamp the measuring probe 4 to stabilize it, so that the measuring probe 4 can be better stabilized at the bottom of the drone body 1 to prevent the measuring probe 4 from falling off during the detection process. At the same time, the anti-slip pad 64 can increase the friction between the L-shaped plate 63 and the measuring probe 4, so as to maintain better stability.

[0044] The implementation principle of the drone equipped with the earthwork measurement device in this embodiment is as follows: when in use, the T-shaped block 3 is first pushed into the T-shaped groove. At this time, the inner wall of the T-shaped groove will squeeze the block 32 into the inside of the sliding groove 31, so that the T-shaped block 3 can better enter the T-shaped groove. When the T-shaped block 3 is fully inserted, the sliding groove 31 will be parallel to the card slots 34 on both sides. At this time, after the card block 32 loses its extrusion, the spring 33 will rebound and push the card block 32 into the inside of the card slot 34. Through the mutual cooperation between the card block 32 and the card slot 34, the measuring probe 4 and the drone body can be realized. 1, which effectively improves the practicability of the device. Then, the electric telescopic rod 61 is started to drive the two C-shaped plates 62 to shrink, so as to drive the two L-shaped plates 63 to gradually fit with the side and bottom surfaces of the measuring probe 4. The measuring probe 4 can be clamped and stabilized by the two L-shaped plates 63, so that the measuring probe 4 can be better stabilized at the bottom of the drone body 1, and the measuring probe 4 can be prevented from falling off during the detection process. At the same time, the friction between the L-shaped plate 63 and the measuring probe 4 can be increased by the anti-slip pad 64, so as to maintain better stability.

[0045] In addition, when the measuring probe 4 is stable, the drone body 1 can be turned on for flight detection. During the detection process, dust floating in the air will be adsorbed on the lens of the measuring probe 4. At this time, the motor 53 can be started to drive the screw rod 52 to rotate. When the screw rod 52 rotates, the movable plate 55 will move back and forth on the screw rod 52 under the guidance of the guide rod 54. The reciprocating movement of the movable plate 55 will drive the cleaning brush 56 at the bottom to move back and forth to clean the lens of the measuring probe 4, so that the lens can always remain clear, reducing the blur of the lens that affects the detection result;

[0046] Secondly, when the cleaning brush 56 needs to be replaced after being used for a long time, the pressing blocks 58 on both sides can be manually pressed to move in the adjustment groove 57 to squeeze the spring 2 59 to contract. When the pressing block 58 moves, it will drive the limit block 510 to move together, so that the limit block 510 is pulled out of the groove, thereby releasing the connection between the movable plate 55 and the cleaning brush 56 to replace the cleaning brush 56. After the replacement is completed, the limit block 510 is reinserted into the groove. At this time, the pressing block 58 is released. According to the rebound of the spring 2 59, the pressing block 58 can always be pushed forward, so that the limit block 510 can always be in the groove, thereby limiting and stabilizing the cleaning brush 56.
