The sliding plate 15 is fixedly connected to the connecting rod 12. The connecting rod 12 penetrates through the support plate 3 and is fixedly connected to the rear end of the protection frame 16.

[0035] The beneficial effects of the above technical solution are as follows:

[0036] When the driving motor works, it can drive the wheel 2 to rotate. When the wheel 2 rotates, it can drive the base body 1 to move. The base body 1 is equivalent to a chassis. A suspension system can be provided between the wheel 2 and the base body 1.

Embodiment 3

[0038] On the basis of Embodiment 2, as Figures 1-7 shown, the protection and cleaning mechanism includes a bottom plate 3 arranged at the rear side of the lower end of the protection frame 16. A first cavity is provided inside the bottom plate 3. A first sliding opening is provided at the front end of the bottom plate 3. First sliding openings are respectively provided at the upper and lower ends and the left and right sides of the bottom plate 3. A first contact block 37 is slidably arranged at the upper end of the bottom plate 3. The lower inclined section of the first contact block 37 is slidably connected to the rear inclined section of a second contact block 30 in the first cavity. The second contact block 30 passes through the first sliding opening and communicates with the outside. A worm 62 is rotatably provided at the front end of the second contact block 30. The worm 62 meshes with a worm gear 31. The worm gear 31 is fixedly connected to a first connecting shaft 32. The first connecting shaft 32 penetrates through the front end of a first connecting block 33 and enters the second cavity inside the first connecting block 33 and is fixedly connected to a first belt pulley. A second belt pulley is also provided in the second cavity. A conveyor belt is provided between the first belt pulley and the second belt pulley. The second belt pulley is fixedly connected to a cleaning head 36 through a second connecting shaft. A through hole for the second connecting shaft to pass through is provided at the front end of the first connecting block 33. The cleaning head 36 is correspondingly arranged with the collection port 19. The cleaning head 36 is rotatably connected to the first connecting block 33;

[0039] Connecting frames 35 are symmetrically arranged at the left and right ends of the first connecting block 33. The first connecting block 33, the connecting frames 35 and the cleaning head 36 are all arranged in the groove at the rear side of the protection port. A reset spring is fixedly provided between the first connecting block 33 and the groove. The left and right connecting frames 35 respectively pass through the left and right first sliding openings and enter the first cavity and are fixedly connected to a second connecting block 34. The left and right second connecting blocks 34 are respectively arranged at the rear sides of the left and right ends of the second contact block 30. Positioning rods 63 are respectively provided at the front sides of the left and right ends of the second contact block 30. The positioning rods 63 are correspondingly matched with positioning grooves 20. The positioning grooves 20 are arranged on the left and right sides of the protection shaft 29. The positioning grooves 20 are arranged in a bevel groove type;

[0040] The driving mechanism includes a first gear 28 fixedly connected to the left end of a worm 62. The first gear 28 meshes with a second gear 27 correspondingly. The second gear 27 is fixedly connected to the outside of a driving sleeve. The left end of the driving sleeve is fixedly connected to a first motor 18. The first motor 18 is fixedly connected to the left end of a protection frame 16. A friction hole is provided at the right end of the driving sleeve, and the friction hole is correspondingly matched with a protection shaft 29 penetrating through the left end of a protection opening.

[0041] The beneficial effects of the above technical solution are as follows:

[0042] When the first motor 18 works, it drives the driving sleeve to rotate. The frictional force between the friction hole in the driving sleeve and the protection shaft 29 is large enough so that the driving sleeve drives the protection shaft 29 to rotate by friction. The protection shaft 29 drives the protection shell 17 to rotate. During the process of collecting geographical information, it is necessary to avoid the collection port 19 corresponding to the rear end of the protection port, so that the information collected by the binocular camera is the rear end area of the protection port. After the binocular camera finishes collecting geographical information, control the protection shaft 29 to rotate so that the protection shell 17 moves upward towards the upper end of the bottom plate 3. After the side end of the protection shell 17 contacts the first contact block 37 at the upper end of the bottom plate 3, it drives the first contact block 37 to move downward. The inclined end on the lower side of the first contact block 37 is slidably connected to the inclined end on the rear side of the second contact block 30. The first contact block 37 pushes the second contact block 30 to move forward. The second contact block 30 drives the worm 62, the first gear 28, the positioning rod 63 and the second connecting block 34 to move. The second connecting block 34 drives the connecting frame 35 to move. The connecting frame 35 drives the first connecting block 33 to move. The first connecting block 33 drives the worm gear 31 to move through the first connecting shaft 32, so that the worm gear 31 is always meshed with the worm 62. The first connecting block 33 drives the cleaning head 36 to move. The reset spring is stretched. A number of cleaning hairs are provided at one end of the cleaning head 36 close to the protection shell 17. When the protection shell 17 rotates, the cleaning brush moves towards the collection port 19. Since the cleaning hairs can deform, when the cleaning hairs contact the side end of the protection shell 17 before entering the collection port 19, they can deform, so that the protection shell 17 can rotate normally. During the rotation of the protection shaft 29, the positioning groove 20 rotates towards the positioning rod 63, and the positioning rod 63 moves towards the protection shaft 29 synchronously. The positioning groove 20 is set in a bevel groove type, so that the positioning rod 63 can continue to move along the inclined section of the bevel groove of the positioning groove 20 after entering the positioning groove 20 until the positioning rod 63 contacts the straight section of the positioning groove 20. The positioning rod 63 limits the protection shaft 29, so that the protection shaft 29 cannot rotate, and the driving sleeve starts to rotate idly. At this time, the first gear 28 just meshes with the second gear 27, and the cleaning head 36 just enters the collection port 19. When the driving sleeve rotates idly, it drives the second gear 27 to rotate. The second gear 27 drives the first gear 28 to rotate. The first gear 28 drives the worm 62 to rotate. The worm 62 drives the worm gear 31 to rotate. The worm gear 31 drives the first pulley to rotate through the first connecting shaft 32. The first pulley drives the second pulley to rotate through the conveyor belt. The second pulley drives the cleaning head 36 to rotate through the second connecting shaft. When the cleaning head 36 rotates, it can clean the lens of the binocular camera, eliminating the need for manual cleaning, saving time and effort. And after the binocular camera finishes collecting geographical information, make the collection port 19 correspond to the rear end of the protection port, avoiding the collection port 19 being exposed to the outside, so that the lens of the binocular camera is easily affected by the external environment. If there are stains on the lens of the binocular camera, the geographical information collection work can also be stopped and the cleaning work can be carried out. Due to the setting of the reset spring, when the binocular camera conducts geographical information collection work again, the first motor 18 works in the reverse direction to drive the driving sleeve to rotate in the reverse direction, and the positioning rod 63 moves away from the positioning groove 20.At this time, the inclined section of the groove opening of the positioning groove 20 plays a boosting role in the movement of the positioning rod 63, so that the positioning rod 63 cannot limit the protection shaft 29, the driving sleeve can drive the protection shaft 29 to reverse, the protection shaft 29 drives the protection shell 17 to reverse, so that the collection port 19 no longer corresponds to the rear end of the protection port, and under the elastic action of the return spring, the first contact block 37, the second contact block 30, the worm 62, the first gear 28, the positioning rod 63, the second connecting block 34 and the connecting frame 35 return to their original positions. Embodiment 4

[0043] On the basis of Embodiment 3, as Figures 1-7 shown, it further includes an auxiliary leveling component, and the auxiliary leveling component further includes a wire winding wheel 25. The wire winding wheel 25 is fixedly connected to the protection shaft 29 passing through the right end of the protection port. A pull rope 26 is wound around the wire winding wheel 25. The pull rope 26 is connected to four connecting ropes 22. The four connecting ropes 22 are respectively connected to the upper end corners of the gravity block 21. The upper end of the gravity block 21 is in corresponding contact with the rolling ball 23. The rolling ball 23 is rotatably connected to the lower end of the fixed part of the telescopic block 24. The movable part of the telescopic block 24 is rotatably connected to the protection shaft 29.

[0044] The beneficial effects of the above technical solutions are as follows:

[0045] The auxiliary leveling component is used to ensure that the upper and lower ends of the protection shell 17 are kept horizontal with the ground in the geographical information collection area, so that the binocular camera is in a horizontal state. When the protection shaft 29 deflects along with the protection frame 16 or the protection shaft 29 rotates itself, the wire winding wheel 25 will deflect. When the wire winding wheel 25 deflects, the pull rope 26 wound on it will loosen or tighten. The four connecting ropes 22 are connected to the upper end corners of the gravity block 21, ensuring that the gravity block 21 is always perpendicular to the ground under the action of gravity, so its upper end is parallel to the ground. When the pull rope 26 wound on the wire winding wheel 25 loosens or tightens, it will drive the gravity block 21 to move up and down. The gravity block 21 drives the telescopic block 24 to expand and contract. Under the action of gravity, the telescopic block 24 is also perpendicular to the ground. The setting of the rolling ball 23 can reduce the friction between the telescopic block 24 and the gravity block 21. After the gravity block 21 and the telescopic block 24 stop shaking, the product of the ratio of the telescopic change value of the telescopic block 24 to the outer diameter of the wire winding wheel 25 and 360° is the rotation angle of the protection shell 17. A distance sensor is arranged in the telescopic block 24. By detecting the telescopic length of the telescopic block 24 with the distance sensor, the telescopic length of the telescopic block 24 when the protection shell 17 is in a horizontal state is set as the target length. In subsequent leveling of the protection shell 17 each time, it can be judged whether the protection shell 17 is leveled by judging whether the telescopic length of the telescopic block 24 is the same as the target length, and then judge whether the binocular camera is in a horizontal state.

[0049] The beneficial effects of the above technical solution are:​

[0050] The mounting block III 48 can be telescopic. When the assisting mechanism works, the working motor drives the first mounting shaft 53 to rotate. The first mounting shaft 53 drives the convex block 51 to rotate. During the process of the convex block 51 rotating 90°, when the protruding ends on its left and right sides rotate to the upper and lower sides, the protruding end with a longer arc length first contacts the second mounting plate 58 and pushes the second mounting plate 58 to move downward. The second mounting plate 58 drives the first mounting plate 57 to move downward through a number of first springs 56. The first mounting plate 57 drives the mounting block III 48 and a number of assisting rods 54 to move downward. Since the fourth mounting plate 59 cannot move downward under the action of the limiting block at this time and the rack 40 cannot move, the mounting block III 48 extends. During the downward movement of the first mounting plate 57, it also drives the guiding block 60 to slide along the guiding groove 55, and the second spring is compressed. A number of first springs 56 and the guiding block 60 are in the same vertical plane, and the elastic force of the first springs 56 is large enough to prevent the first mounting plate 57 from deflecting during the process of driving the first mounting plate 57 to move downward by a number of first springs 56. The first mounting plate 57 drives a number of assisting rods 54 to extend out of the moving port 52 until the assisting rods 54 contact and press against the depression where the real-scene three-dimensional geographic information acquisition device of the present invention is located. Then the first mounting plate 57 cannot continue to move downward, and a number of first springs 56 begin to be gradually compressed until the protruding end with a shorter arc length contacts the lower end of the fourth mounting plate 59 and pushes the fourth mounting plate 59 to move upward. The fourth mounting plate 59 drives the rack 40 to move upward. When the rack 40 moves upward, it drives the third gear 41 to rotate. The third gear 41 drives the second mounting shaft 46 to rotate downward. The second mounting shaft 46 drives the first operating block 64 to rotate downward. The first operating block 64 and the second mounting shaft 46 jointly drive the rotating block 43 to rotate. The rotating block 43 drives the fourth mounting shaft 42 to rotate. The fourth mounting shaft 42 drives the second mounting block 39 to move upward through the first mounting block 44. The second mounting block 39 drives the mounting block III 48 to move upward through the fifth mounting shaft 47. The mounting block III 48 continues to extend until the mounting block III 48 can no longer extend. At this time, the mounting block III 48 drives the side of the first mounting plate 57 close to the base body 1 to rotate upward. The guiding block 60 is slidably connected to the support shaft, and the support shaft is rotatably connected to the first mounting plate 57, so that the first mounting plate 57 can rotate a certain angle with the support shaft as the center. At this time, the first spring 56 is deformed. The position of the support shaft is located between the mounting block III 48 and a number of assisting rods 54 in the left-right direction. Therefore, a number of assisting rods 54 tend to rotate downward with the support shaft as the center. Since the assisting rods 54 contact the depression where the real-scene three-dimensional geographic information acquisition device of the present invention is located, the assisting rods 54 exert a force on the depression, and under the reaction force of the depression, the assisting rods 54 can drive the real-scene three-dimensional geographic information acquisition device of the present invention to move. At the same time when the protruding end with a longer arc length of the convex block 51 is separated from the second mounting plate 58, the protruding end with a shorter arc length of the convex block 51 is also separated from the first mounting plate 57. Under the elastic action of the first spring 56 and the elastic action of the second spring, the first mounting plate 57 and the second mounting plate 58 return to their original positions, and the assisting rods 54 return to their original positions.The gravity of the mounting plate 4 59 is large enough, so that after the protruding end with a shorter arc length of the protruding block 51 is out of contact with the mounting plate 4 59, the mounting plate 4 59 moves downward under the action of gravity and contacts the limit block, thereby returning to its original position, thereby allowing the rack 40, the gear 3 41 and the mounting shaft 2 46 connected thereto to return to their original positions, the mounting shaft 2 46 drives the operating block 1 64 and the rotating block 43 to return to their original positions, the rotating block 43 drives the mounting shaft 42, the mounting block 1 44, the mounting block 2 39, the mounting shaft 5 47 and the mounting block 3 48 to return to their original positions, and through the continuous rotation of the protruding block 51, the power-assisting rod 54 can repeat the above-mentioned steps of extending out of the movable opening 52 and rotating a certain angle until the wheel 2 finds a new fulcrum, thereby facilitating the wheel 2 to drive the real-scene three-dimensional geographic information acquisition device of the present invention to leave the mud pit and continue to move. The power-assist mechanism of the present invention is used to automatically carry out subsequent geographic information collection work. When the power-assist mechanism of the present invention is working, the power-assist rod 54 is first extended and then rotated to a certain angle, and then returns to its original position and continues to repeat the steps of first extending and then rotating to a certain angle. The action of the power-assist rod 54 is equivalent to the paddling action. Compared with the use of a motor to directly drive the power-assist rod 54 to rotate eccentrically, the power-assist mechanism is small in size, thereby reducing the volume of the real-scene three-dimensional geographic information collection device of the present invention, which is conducive to improving the mobility and passing performance of the real-scene three-dimensional geographic information collection device of the present invention. The setting of the operating block 2 38 allows it to be unfolded along the installation axis 3, which is convenient for the staff to pull the real-scene three-dimensional geographic information collection device of the present invention to move through the operating block 2 38. The power-assist mechanism is set on the front and rear sides of the base 1, and the power-assist mechanism on the corresponding side can be selected to work according to actual conditions.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
