[0002] A road slope measuring device is disclosed in the related technology (publication number: CN117824591A), which comprises a vehicle plate. The top end surface of the vehicle plate is fixedly connected with a slope and roll detection assembly. The slope and roll detection assembly comprises a support plate fixed at the middle position of the top end surface of the vehicle plate. The top end surface of the support plate is fixedly connected with a concave frame. The concave groove inside the concave frame is detachably connected with a first measuring disc through a connecting piece. The side top end of the first measuring disc is rotatably connected with a counterweight arrow. The top end of the outer side of the concave frame is fixedly connected with two symmetrical roll detection mechanisms. The roll detection mechanism comprises a second measuring disc fixed at the top end of the outer side of the concave frame. The second measuring disc is fixedly connected with a reinforcing rod between one side and the outer side of the concave frame. The concave frame on one side of the reinforcing rod is rotatably connected with a thimble. The bottom end of the thimble is fixedly connected with a rope body. The bottom end of the rope body is fixedly connected with a counterweight ball. The top end of the thimble is fixedly connected with a foam plate pointer.

[0003] In the process of implementing the above-mentioned embodiments, it is found that at least the following problems exist in the related technology:

[0036] Combine Figures 1 to 4As shown, an embodiment of the present disclosure provides a slope surveying device, comprising a base plate 1, an optical axis 2, a top plate 3, a first longitudinal rotation axis 4, a profile plate 5, a transverse rotation axis 6, a first angle sensor 7, a detection arm 8, and a drive member. The optical axis 2 is mounted on the top surface of the base plate 1 and is used to support the mounting of the top plate 3. The top plate 3 is mounted on the top end of the optical axis 2, with the plane of the top plate 3 being parallel to the plane of the base plate 1, and is used to support the relevant components of the mounting device. The first longitudinal rotation axis 4 is rotatably disposed through the top plate 3, with the axis of the first longitudinal rotation axis 4 being perpendicular to the plane of the top plate 3, and the first longitudinal rotation axis 4 being capable of rotational motion relative to the top plate 3.

[0037] The embodiment of the present disclosure provides a slope surveying device. When the device is placed on the slope of a road, the detection arm 8 can be deflected under the action of gravity and the support of the transverse rotating shaft 6. This in turn drives the detection end of the first angle sensor 7 to deflect. At this time, the first angle sensor 7 can detect the deflection angle of the detection arm 8. Then, based on the deflection angle of the detection arm 8, the slope of the road can be calculated. Compared with the method of reading by viewing the dial with the human eye, the operation is simple and convenient. By controlling the operation of the driving member, the first longitudinal rotating shaft 4 can be driven to rotate and the rotation angle of the first longitudinal rotating shaft 4 can be detected. Finally, the direction of the detection arm 8 is changed to detect the slope of the road in different directions.
