A motor 44 is installed on the mounting frame 43. The motor 44 is provided with a low-speed rotation mode. A rotating wheel 45 is rotatably installed on the mounting frame 43. The output end of the motor 44 is connected to the rotating wheel 45. The rotating wheel 45 is connected to a propeller 46. The four propellers 46 drive the frame 1 to fly by rotating. An adjusting hydraulic cylinder 48 is installed on the mounting arm 41. An adjusting block 47 is connected to the connecting piece 42. The telescopic end of the adjusting hydraulic cylinder 48 is hinged to the adjusting block 47. When the adjusting hydraulic cylinder 48 is extended, the lever is used to move away from the adjusting block 47 to drive the connecting piece 42 to rotate. When the connecting piece 42 rotates, the mounting frame 43 is driven to flip downward, and the mounting frame 43 drives the rotating wheel 45 to flip synchronously. When the four rotating wheels 45 flip to be perpendicular to the ground, the four adjusting hydraulic cylinders 4 8 stops extending and enters the pressure-maintaining state, contracts the four landing hydraulic cylinders 2, and the four landing hydraulic cylinders 2 drive the two landing gears 3 to move upward, so that the four rotating wheels 45 are in contact with the ground, and the motor 44 drives the rotating wheels 45 to rotate in the low-speed rotation mode, and the four rotating wheels 45 drive the frame 1 to travel on the ground, so that the frame 1 can switch between the flight mode and the land mode according to the actual working conditions to meet different usage requirements; a mounting plate 49 is installed on the mounting arm 41, and a shock-absorbing plate 410 is installed on the mounting plate 49 through a plurality of springs.

When the mounting frame 43 is perpendicular to the ground, the shock-absorbing plate 410 keeps in contact with the mounting frame 43, and the shock-absorbing plate 410 keeps in contact with the mounting frame 43. The multiple springs between the mounting plates 49 can achieve a shock-absorbing effect, so that when the frame 1 is traveling on the ground, the vibrations received by the four rotating wheels 45 are transmitted to the four mounting frames 43, and the four shock-absorbing plates 410 absorb the vibration forces on the four mounting frames 43 respectively, thereby achieving a shock-absorbing effect; through the cooperation of the frame 1, the lifting and lowering hydraulic cylinder 2, the landing gear 3 and the wing assembly 4, the frame 1 can switch between the flight mode and the land driving mode according to the use conditions to meet different use requirements, thereby expanding the scope of use and increasing applicability; through the provision of the shock-absorbing plates 410, the vibrations received by the frame 1 when traveling on land can be partially absorbed by the four shock-absorbing plates 410, thereby reducing the wear of the frame 1 and the wing assembly 4 and extending their service life.

[0037] For further information, see Figure 8 - Fig.11 , a protection component 5 is used to protect the camera 7. The protection component 5 is arranged on the four lifting and lowering hydraulic cylinders 2. There are two protection components 5. The two protection components 5 are respectively located below the two cameras 7. The protection component 5 includes two upper connecting rods 51 and two lower connecting rods 52. The two upper connecting rods 51 are respectively hinged to the outer walls of the fixed sections of two of the lifting and lowering hydraulic cylinders 2. The two lower connecting rods 52 are respectively hinged to the outer walls of the telescopic sections of two of the lifting and lowering hydraulic cylinders 2. A connecting block 53 is hinged between the lower connecting rod 52 and the upper connecting rod 51 on the lifting and lowering hydraulic cylinder 2. A mounting plate 54 is connected between the two connecting blocks 53. A transparent cover 55 is connected to the mounting plate 54. The two transparent covers 55 are respectively located outside the two cameras 7 during the movement. The lifting and lowering hydraulic cylinders 2 are respectively hinged to the outer walls of the telescopic sections of two of the lifting and lowering hydraulic cylinders 2. When the pressure cylinder 2 contracts, the upper connecting rod 51 and the lower connecting rod 52 drive the connecting block 53 to move away from the lifting and lowering hydraulic cylinder 2. The two connecting blocks 53 drive the transparent cover 55 to move synchronously through the mounting plate 54, so that the transparent cover 55 moves to the vicinity of the camera 7 to protect the camera 7 and prevent the camera 7 from being damaged by collision with debris in the air or on the ground during the movement of the frame 1. The transparent cover 55 is transparent and has little effect on the field of view of the camera 7. The protection component 5 also includes a slide rail 56, which is installed between the fixed sections of two lifting and lowering hydraulic cylinders 2. A pull rod 57 is slidably connected to the slide rail 56. The outer wall of the transparent cover 55 is connected to an inner slider 512, and the inner wall of the inner slider 512 is slidably connected to a rebound rod 5 11. The end of the rebound rod 511 away from the slide rail 56 is connected to a support 510, and two scraping strips 59 are rotatably installed on the support 510. The two scraping strips 59 are respectively hinged with a bent rod 58, and the two bent rods 58 are hinged with the pull rod 57. The pull rod 57 moves up and down due to the limiting skill of the slide rail 56. A spring is arranged between the end of the rebound rod 511 away from the support 510 and the inner slider 512. The two scraping strips 59 are in contact with the transparent cover 55, and the tops of the two scraping strips 59 are slidably connected to the edge of the transparent cover 55. When the transparent cover 55 moves, the pull rod 57 pulls the two scraping strips 59 through the two bent rods 58, so that the two scraping strips 59 slide along the outer surface of the transparent cover 55. When the transparent cover 55 covers the camera 7, the two The scraper strip 59 is located at the connection between the transparent cover 55 and the mounting plate 54 to avoid blocking the field of view of the camera 7. The two scraper strips 59 clean the surface of the transparent cover 55 during relative movement with the surface of the transparent cover 55 to maintain the light transmittance of the transparent cover 55. Through the setting of the protective component 5, the two cameras 7 can be protected by the two transparent covers 55 during operation to avoid damage to the cameras 7 caused by external force collision. Through the setting of the two scraper strips 59, the two scraper strips 59 can clean the transparent cover 55 when the frame 1 starts and ends movement to maintain the transparency of the transparent cover 55 to avoid a lot of dust adhering to the surface of the transparent cover 55 after long-term use, which affects the clarity of the image collected by the camera 7.

[0038] Further, see Fig.12 - Fig.13 , a spraying assembly 6 is used for spraying a cleaning agent. The spraying assembly 6 is arranged on the protective assembly 5. There are two spraying assemblies 6, and the two spraying assemblies 6 are respectively arranged on the two protective assemblies 5. The spraying assembly 6 includes two cleaning agent boxes 61. The two cleaning agent boxes 61 are both installed on one of the mounting plates 54. The cleaning agent box 61 is filled with a cleaning agent. An air pipe 62 is connected to the cleaning agent box 61. An end of the air pipe 62 away from the cleaning agent box 61 is connected to an air bag 63. The air bag 63 is installed on one of the connecting blocks 53. Two sliding shafts 65 are installed on the connecting block 53. A sliding frame 64 is slidably installed on the two sliding shafts 65. Two abutment rods 66 are installed on the sliding frame 64. An atomizing nozzle 67 is installed on the spraying assembly 6. The two atomizing nozzles 67 are respectively located on both sides of the transparent cover 55. A spring is arranged between the sliding frame 64 and the connecting block 53. The upper connecting rod 51 and the lower connecting rod 52 connected to the connecting block 53 When moving, they contact the two abutment rods 66 on the sliding frame 64 respectively. The upper connecting rod 51 and the lower connecting rod 52 push the sliding frame 64 away from the air bag 63 through the two abutment rods 66 during the movement. When the sliding frame 64 is reset, the air bag 63 is squeezed, so that the air bag 63 injects air into the detergent box 61 through the air pipe 62. The detergent box 61 uses the positive pressure to spray the detergent inside it onto the transparent cover 55 through the atomizing nozzle 67. The two atomizing nozzles 67 spray the detergent on both sides of the transparent cover 55 before the scraper 59 cleans, further improving the cleaning effect; through the arrangement of the spraying assembly 6, the atomizing nozzle 67 can spray the detergent on the surface of the transparent cover 55 when the transparent cover 55 starts to move, thereby improving the cleaning effect of the scraper 59, and the spraying of the detergent can also play a maintenance role on the transparent cover 55, maintain the transparency of the transparent cover 55, and extend the service life of the transparent cover 55.

[0039] With the above structure, the working principle of the present invention is that, in the flight state of the frame 1, the motor 44 is started to drive the rotating wheel 45 to rotate, the rotating wheel 45 drives the propeller 46 to rotate, and the four propellers 46 drive the frame 1 to fly by rotating. When the frame 1 lands, the four landing hydraulic cylinders 2 extend downward, so that the distance between the two landing gears 3 and the frame 1 increases. After the two landing gears 3 come into contact with the ground, the staff can switch to the land mode by starting the four adjusting hydraulic cylinders 48. When the adjusting hydraulic cylinders 48 extend, the lever is used to move away from the adjusting block 47 to drive the connecting member 42 to rotate, and the connecting member 42 rotates. When the four wheels 45 are turned vertically to the ground, the four adjusting hydraulic cylinders 48 stop extending and enter the pressure-maintaining state, and the four lifting and lowering hydraulic cylinders 2 are retracted. The four lifting and lowering hydraulic cylinders 2 drive the two landing gears 3 to move upward, so that the four wheels 45 are in contact with the ground. The motor 44 is provided with a low-speed rotation mode. The motor 44 drives the wheels 45 to rotate in the low-speed rotation mode. The four wheels 45 drive the frame 1 to travel on the ground, so that the frame 1 can switch between the flight mode and the land mode according to the actual working conditions. , to meet different usage requirements, the two cameras 7 can collect image information during the movement of the frame 1; when the mounting frame 43 is about to be perpendicular to the ground during the movement, the mounting frame 43 contacts the edge of the shock-absorbing plate 410 and slides along the edge of the shock-absorbing plate 410. When the mounting frame 43 is perpendicular to the ground, the shock-absorbing plate 410 keeps in contact with the mounting frame 43, and the multiple springs between the shock-absorbing plate 410 and the mounting plate 49 can play a shock-absorbing effect, so that when the frame 1 is traveling on the ground, the vibrations received by the four rotating wheels 45 are transmitted to the four mounting frames 43, and the four shock-absorbing plates 410 absorb the four The vibration force on the mounting frame 43 achieves a shock-absorbing effect, thereby avoiding aggravated wear and shortening the service life due to long-term vibration in the driving state; through the cooperation of the frame 1, the landing hydraulic cylinder 2, the landing gear 3 and the wing assembly 4, the frame 1 can switch between the flight mode and the land driving mode according to the use conditions to meet different use requirements, expand the scope of use, and increase applicability; through the setting of the shock-absorbing disc 410, the vibration received by the frame 1 when driving on land can be partially absorbed by the four shock-absorbing discs 410, thereby reducing the wear of the frame 1 and the wing assembly 4 and extending their service life.

[0040] When the frame 1 is flying or starting to drive on land, the two landing gears 3 will rise to the uppermost position of their limited positions to prevent the landing gears 3 from affecting the movement of the frame 1. When the frame 1 is on standby or stops moving, the two landing gears 3 will descend to the lowest position of their limited positions, so that the two landing gears 3 can prop up the frame 1 and the wing assembly 4 for easy recovery. When the frame 1 is converted from standby to start moving, the four landing hydraulic cylinders 2 are retracted. When the landing hydraulic cylinders 2 are retracted, the upper connecting rod 51 and the lower connecting rod 52 drive the connecting block 53 to move away from the landing hydraulic cylinder 2. The connecting block 53 moves obliquely upward to the landing gear 3, and the two connecting blocks 53 drive the mounting plate 54 to move simultaneously. The mounting plate 54 drives the transparent cover 55 to move synchronously, so that the transparent cover 55 moves to the vicinity of the camera 7 to protect the camera 7, and prevent the camera 7 from being damaged by collision with debris in the air or on the ground during the movement of the rack 1. The transparent cover 55 is transparent, and has little effect on the field of view of the camera 7. When the transparent cover 55 moves, the transparent cover 55 moves obliquely upward, and the pull rod 57 is limited by the slide rail 56 to move up and down, so that when the transparent cover 55 moves, the pull rod 57 pulls the two scraping strips 59 through the two curved rods 58, so that the two scraping strips 59 slide along the outer surface of the transparent cover 55. When the transparent cover 55 moves, the pull rod 57 pulls the two scraping strips 59 through the two curved rods 58, and the two scraping strips 59 slide along the outer surface of the transparent cover 55. When the camera 7 is covered, the two scraper strips 59 are located at the connection between the transparent cover 55 and the mounting plate 54 to avoid blocking the field of view of the camera 7. When the two scraper strips 59 are pulled by the pull rod 57, the two scraper strips 59 apply a pulling force to the rebound rod 511 through the support 510. After the transparent cover 55 moves into place, the rebound rod 511 and the support 510 are also located at the connection between the transparent cover 55 and the mounting plate 54 to avoid blocking the field of view of the camera 7. When the frame 1 finishes moving, the landing gear 3 descends, and the transparent cover 55 is reset accordingly. During the reset of the transparent cover 55, the rebound rod 511 is brought by the support 510 through the elastic force of the spring between the rebound rod 511 and the inner slider 512. The two scraping strips 59 are moved to reset, and the two scraping strips 59 clean the surface of the transparent cover 55 during the relative movement with the surface of the transparent cover 55 to maintain the light transmittance of the transparent cover 55; through the setting of the protection component 5, the two cameras 7 can be protected by the two transparent covers 55 during the operation to prevent the cameras 7 from being damaged by external force collision; through the setting of the two scraping strips 59, the two scraping strips 59 can clean the transparent cover 55 when the frame 1 starts and ends the movement to maintain the transparency of the transparent cover 55, to prevent a lot of dust from adhering to the surface of the transparent cover 55 after long-term use, which affects the clarity of the image collected by the camera 7.

[0041] The detergent box 61 is filled with detergent, and the two sliding shafts 65 limit the sliding frame 64. When the landing gear 3 descends, the upper connecting rod 51 and the lower connecting rod 52, which are in contact with the two abutting rods 66 on the sliding frame 64, push the sliding frame 64 away from the airbag 63 through the two abutting rods 66 during the movement. When the landing gear 3 rises, the upper connecting rod 51 and the lower connecting rod 52 lose the thrust on the two abutting rods 66, and the sliding frame 64 is reset by the elastic force of the spring above it. When the sliding frame 64 is reset, it squeezes the airbag 63, so that the airbag 63 injects air into the detergent box through the air pipe 62. In 61, the detergent box 61 uses positive pressure to spray the detergent inside it onto the transparent cover 55 through the atomizing nozzle 67. The two atomizing nozzles 67 spray the detergent on both sides of the transparent cover 55 before the scraper 59 cleans, further improving the cleaning effect; through the setting of the spraying component 6, the atomizing nozzle 67 can spray the detergent on the surface of the transparent cover 55 when the transparent cover 55 starts to move, thereby improving the cleaning effect of the scraper 59, and the spraying detergent can also maintain the transparent cover 55, maintain the transparency of the transparent cover 55, and extend the service life of the transparent cover 55.

[0042] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
