[0044] Reference Figure 8 and Fig. 9 The moving mechanism 9 includes a first rack 91 slidably mounted on the base 1, a moving spring 92 is fixedly connected between the first rack 91 and the base 1, a moving gear 811 meshing with the first rack 91 is fixedly connected to the bidirectional screw 81, and limiting components are installed on the three motors 34. The motor 34 limits the first rack 91 through the limiting component. The limiting component includes a second rack 93 fixedly connected to the motor 34. A third rotating shaft 94 and a fifth rotating shaft 95 are rotatably mounted on the base 1. A fourth conveyor belt is sleeved on the third rotating shaft 94 and the fifth rotating shaft 95. A seventh gear meshing with the second rack 93 is fixedly connected to the third rotating shaft 94, and an eighth gear is fixedly connected to the fifth rotating shaft 95. The fourth rack 96 is meshed with the eighth gear, and the fourth rack 96 is in contact with the first rack 91; when the support rod 22 stably supports the base 1, the motor 34 moves, and the motor 34 drives the second rack 93 to move, the second rack 93 drives the third rotating shaft 94 to rotate, the third rotating shaft 94 drives the fifth rotating shaft 95 to rotate, and the fifth rotating shaft 95 drives the fourth rack 96 to rotate, so that the fourth rack 96 is separated from the first rack 91. When all three motors 34 move, the moving spring 92 can push the first rack 91 to move, the first rack 91 drives the moving gear 811 to rotate, and the moving gear 811 drives the bidirectional screw 81 to rotate, so that the two fixed arc plates 83 are separated from the plumb line 14.

[0045] The implementation principle of a road slope measuring device according to an embodiment of the present invention is as follows: when it is necessary to measure the road slope, the motor 34 is first started, the motor 34 drives the cleaning shaft 35 to rotate, the cleaning shaft 35 drives the cleaning screw 31 to rotate, the cleaning screw 31 drives the cleaning plate 33 to clean the gravel and soil on the road, the cleaning plate 33 drives the crushing shaft 38 to rotate, and the crushing blade crushes the large pieces of soil on the road. At the same time, the cleaning shaft 35 drives the supporting screw 21 to rotate, and the supporting screw 21 drives the supporting rod 22 to move downward. When the supporting rod 22 contacts the ground, the control block 65 is retracted into the control groove, the switch moving piece contacts the switch fixed piece, the battery energizes the electromagnet 61, the electromagnet 61 attracts the iron block 62, and the iron block 62 drives the motor 34 to move, so that the first gear 341 is separated from the second gear 351, and the first gear 341 is meshed with the fifth gear 511. At this time, the motor 34 is turned off. When there is a depression on the ground , when the support rod 22 cannot contact the ground, the support rod 22 moves to the bottom of the support screw 21, the fourth gear 241 meshes with the third gear 281, and the support screw 21 drives the flipping lever 26 to flip to a horizontal state. The flipping lever 26 increases the contact area between the support rod 22 and the ground, so that the support rod 22 stably supports the base 1, and the flipping lever 26 pushes the abutment rod 66 to move, and the abutment rod 66 pushes the control block 65 back into the control groove, and the switch moving piece can also contact the switch fixed piece, and the motor 34 moves, and the motor 34 is turned off. The motor 34 drives the second rack 93 to move, and the second rack 93 drives the fourth rack 96 to rotate, so that the fourth rack 96 is separated from the first rack 91. After the three motors 34 have moved, the moving spring 92 drives the first rack 91 to move, and the first rack 91 drives the bidirectional screw 81 to rotate, so that the two fixed arc plates 83 are separated from the plumb line 14, and the slope of the road can be measured.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
