[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 , the utility model provides the following technical solutions:

[0024] Embodiment 1: In order to solve the problem that there is a lot of sand on the surface of the dam in the prior art, the landing gear will not be in complete contact with the slope, the force between the landing gear and the slope is relatively small, and the slope is prone to make the drone unstable and slide, and the instability of the drone will affect the monitoring of the slope, the following technical solution is disclosed, see Figure 1-Figure 2 and Figure 5 As shown, a dam surface deformation monitoring device includes a monitoring instrument 5 installed at the upper end of a drone body 1; and also includes: a cleaning mechanism, which is arranged at the lower part of the drone body 1, and scrapes the sand covered on the dam surface by rotating a scraper 6; a motor 16 is installed at the upper end of the drone body 1, and the output end of the motor 16 is key-connected to a rotating column 13, and the interior of the rotating column 13 is slidably connected to a transmission rod 10, the cleaning mechanism includes a moving rod 7, which is slidably connected to the interior of the scraper 6, and the moving rod 7 is a conical structure, and the upper end of the scraper 6 is fixed to the lower end of the transmission rod 10, and the scraper 6 is an "L"-shaped structure, a water tank is installed on the scraper 6, the water tank is connected to the interior of the scraper 6, and a through hole is arranged at the lower end of the scraper 6.

[0025] Support springs 17 are provided between the transmission rod 10 and the rotating column 13 and between the moving rod 7 and the scraper 6 . The transmission rod 10 is a prismatic structure, and the outer side of the transmission rod 10 fits with the inner side of the rotating column 13 .

[0026] A lower controller 11 is installed at the lower end of the transmission rod 10 , and the lower controller 11 is electrically connected to the motor 16 . The lifting distance of the transmission rod 10 is equal to the distance that the transmission rod 10 protrudes from the lower end of the drone body 1 .

[0027] When it is necessary to monitor the deformation degree of the dam surface, the drone body 1 is flown to the specified position through remote control, and the dam surface is monitored by the monitoring instrument 5. When an emergency landing is required on the slope of the dam, the drone body 1 tilts downward and lands. After the lower controller 11 descends and contacts the dam surface, the dam surface squeezes the lower controller 11, and the lower controller 11 operates the motor 16. The motor 16 rotates the rotating column 13, and the rotation of the rotating column 13 drives the transmission rod 10 to rotate synchronously. The rotation of the transmission rod 10 drives the scraper 6 to rotate synchronously. The rotation of the scraper 6 drives the moving rod 7 to rotate synchronously. The moving rod 7 and the scraper 6 rotate to scrape the sand on the dam surface. At the same time, the water inside the water tank is sprayed out through the scraper 6, and the water flushes the sand on the dam surface to avoid the drone body 1 from contacting the sand on the dam surface after landing, so that the drone body 1 can land steadily without sliding.

[0028] Embodiment 2: Add a new technical solution based on Embodiment 1, see Figure 2-Figure 4 As shown, the connecting tube 4 is installed at equal angles around the drone body 1, and the lower end of the connecting tube 4 is installed with a hollow rubber 3, the lower end of the hollow rubber 3 is flush with the lower end of the drone body 1, the drone body 1 is slidably connected with an extrusion plate 9, and the drone body 1 is installed with an airbag 14, the airbag 14 is located above the extrusion plate 9, and the airbag 14 is connected to the connecting tube 4. The drone body 1 is slidably connected with a lifting frame 2, and a connecting spring 8 is installed between the upper end of the lifting frame 2 and the drone body 1, and an upper controller 15 is installed inside the lifting frame 2, and the upper controller 15 is electrically connected to the motor 16;

[0029] When the drone body 1 continues to descend, the ground pushes the lifting frame 2 to move upward. When the lifting frame 2 moves upward to push and squeeze the upper controller 15, the upper controller 15 stops the motor 16. During the upward movement of the lifting frame 2, the connecting rod 12 is driven to move upward synchronously. During the upward movement of the connecting rod 12, the squeezing plate 9 is driven to move upward synchronously. When the squeezing plate 9 moves upward to squeeze the airbag 14, the gas inside the airbag 14 enters the hollow rubber 3 through the connecting pipe 4, thereby expanding the hollow rubber 3. After the hollow rubber 3 expands, the contact area with the inclined surface is increased, thereby making the drone body 1 stably located on the slope without sliding.
