The hand-held part 20 is spherical in shape, a switch for controlling the electric push rod 12 to be turned on is installed on the column 19, and when the electric push rod 12 is started, the second connecting plate 10 and the first shell 9 can be driven to move horizontally on the back of the base plate 1, so that after completing the single-point measurement and recording of the slope, the position of the recording paper 16 can be automatically changed, so as to facilitate the recording of the result of the next measurement point.

[0032] The recording paper 16 is made of hard cardboard, which is convenient for subsequent removal.

[0033] As a further explanation of this embodiment, the clamping mechanism includes a second shell 13, and notches are provided at the top and one side of the second shell 13. The second shell 13 is fixed inside the first shell 9, and the top of the second shell 13 is flush with the top of the first shell 9. One end of the first spring 15 is fixedly connected to the inside of the second shell 13, and the other end of the first spring 15 is fixedly connected to a clamping plate 14, and the clamping plate 14 is movably configured inside the second shell 13. The recording paper 16 is clamped between the clamping plate 14 and a side wall of the second shell 13. Specifically, a rectangular groove matching the second shell 13 is provided on the top of the first shell 9, and the notch at the top of the second shell 13 is used to take and place the recording paper 16, and the notch on one side of the second shell 13 is used to leak the recording paper 16 to facilitate the recording of measurement results.

[0034] As a further explanation of this embodiment, one end of a pull rod 17 is fixedly connected to one side of the clamp 14 away from the recording paper 16, and the other end of the pull rod 17 passes through the second shell 13 and is fixedly connected to a pull plate 18. When the pull plate 18 is pulled outward, the pull plate 18 can drive the pull rod 17 and the clamp 14 to move outward and compress the first spring 15. At this time, the clamping of the recording paper 16 can be released, and then the recording paper 16 can be taken out from the inside of the second shell 13. Similarly, when the pull plate 18 is pulled outward, the recording paper 16 can also be placed between the clamp 14 and the side wall of the second shell 13. Then, the pull plate 18 is released, the first spring 15 is reset, and the recording paper 16 can be clamped and fixed.

[0035] A rotating shaft 3 is installed inside the support plate 2 through a bearing. A circular tube 5 is coaxially fixed to the rotating shaft 3 located on the left side of the support plate 2. A first connecting rod 7 is fixedly connected to the bottom of the circular tube 5. A counterweight ball 8 is fixedly connected to the other end of the first connecting rod 7. A recording mechanism for recording the slope on a recording paper 16 is provided on the circular tube 5. After the device is moved to the slope, under the action of gravity, the counterweight ball 8 will rotate to be perpendicular to the ground. The rotation of the counterweight ball 8 can drive the circular tube 5 and the rotating shaft 3 to rotate.

[0036] As a further explanation of this embodiment, the recording mechanism includes an arc block 6 fixedly connected to the outer surface of the circular tube 5, a slide groove is opened inside the arc block 6, a slider 23 is slidably configured inside the slide groove, one side of the slider 23 is fixedly connected to one end of a second spring 24, the other end of the second spring 24 is fixedly connected to the inner wall of the slide groove, the front of the slider 23 is fixedly connected to a moving plate 21, and the left side of the moving plate 21 is fixedly inlaid with a graphite core 22. When the circular tube 5 rotates, the arc block 6, the moving plate 21 and the graphite core 22 can be driven to rotate accordingly, and the moving plate 21 and the slider 23 will compress the second spring 24 when they slide to the left.

[0037] As a further explanation of this embodiment, the movable plate 21 is fixedly connected to one end of the second connecting rod 25, and the other end of the second connecting rod 25 is rotatably connected to a circular plate 26. The middle part of the second connecting rod 25 is slidably configured in the arc groove 31, and the arc groove 31 is opened on the support plate 2.

[0038] As a further explanation of this embodiment, the recording mechanism also includes an annular plate 27, and a first track groove 28 and a second track groove 29 are opened inside the annular plate 27, and the first track groove 28 and the second track groove 29 are connected. The second connecting rod 25 is slidably arranged inside the first track groove 28 at one end away from the graphite core 22, and the circular plate 26 is slidably arranged inside the second track groove 29. Through the cooperation between the second connecting rod 25, the circular plate 26, the first track groove 28 and the second track groove 29, the annular plate 27 can move in the horizontal direction to drive the movable plate 21 and the graphite core 22 to move accordingly without affecting the rotation of the movable plate 21 and the graphite core 22.

[0039] As a further explanation of the present embodiment, a right-angle rod 30 is fixedly connected to the outer circumferential surface of the annular plate 27, and a through hole is opened inside the column 19 for the right-angle rod 30 to slide horizontally. The end of the right-angle rod 30 away from the annular plate 27 passes through the through hole and is fixedly connected to a limiting plate. The through hole is located near the top of the column 19. When the staff grips the handle 20, the remaining fingers can be freed to grip the right-angle rod 30 inward. The horizontal inward movement of the right-angle rod 30 can drive the annular plate 27, the movable plate 21 and the graphite core 22 to move inward and compress the second spring 24.

[0040] As a further explanation of this embodiment, an angle scale 36 is fixedly embedded inside the support plate 2, and a pointer 4 corresponding to the angle scale 36 is fixedly connected to the outer surface of the rotating shaft 3 located on the right side of the support plate 2. The rotation of the rotating shaft 3 can drive the pointer 4 to rotate accordingly. When only the single-point slope of the slope needs to be measured, after moving the device to the measuring point, it is only necessary to observe the position of the angle scale 36 pointed by the pointer 4 to obtain the measurement result.

[0041] When measuring the slope of the land, first hold the handheld part 20 and push the device to the designated measuring point, then press the handheld part 20 downward forcefully to stabilize the device. At this time, the counterweight ball 8 will rotate to be perpendicular to the ground under the action of gravity. The rotation of the counterweight ball 8 can drive the circular tube 5, the pointer 4, the arc block 6, the movable plate 21 and the graphite core 22 to rotate. When the pointer 4 is stable, press the right-angle rod 30 inward, and the right-angle rod 30 can drive the annular plate 27, the movable plate 21 and the graphite core 22 to move inward and compress the second spring 24. When the annular plate 27 moves inward to the maximum extent, the graphite core 22 will move to contact the recording paper 16, and a diagonal line can be printed on the recording paper 16. After the recording paper 16 is taken out, a vertical line is drawn from the top of the diagonal line. By measuring the angle between the vertical line and the diagonal line, the slope of the point can be obtained. After the diagonal line is drawn. Loosen the right-angle rod 30. Under the action of the second spring 24, the annular plate 27, the movable plate 21 and the graphite core 22 will move to the reset position. Then, push the device to the next measuring point and repeat the above steps to achieve multi-point measurement of the slope. The entire measurement process eliminates the steps of fixing and releasing the device and manually recording the measurement results, thereby effectively saving manpower and time and improving measurement efficiency. During the entire measurement process, the staff does not need to observe the measurement results, thereby avoiding the staff from observing the measurement results incorrectly due to fatigue and other reasons, thereby ensuring the accuracy of the measurement.

[0042] Embodiment 2

[0043] See also Figure 2 and Fig. 9 The difference between the second embodiment of the present invention and the first embodiment is that the device can be pushed to move, saving the physical strength of the staff during the slope measurement process.

[0044] A plurality of running mechanisms are arranged at the bottom of the base plate 1 . The number of the running mechanisms is four and they are evenly distributed at the bottom of the base plate 1 .

[0045] As a further explanation of this embodiment, the walking mechanism includes a storage groove 32 opened inside the bottom plate 1, and the inside of the storage groove 32 is slidably connected to a lifting plate 34, and a ball 35 is rotatably installed at the bottom of the lifting plate 34, and one end of a third spring 33 is fixedly connected to the upper surface of the lifting plate 34, and the other end of the third spring 33 is fixedly connected to the inner wall of the storage groove 32. During the movement of the device, the ball 35 contacts the ground, thereby pushing the device to move, saving the physical strength of the staff, and when the device moves to the measuring point and presses the handheld part 20 downward with force, the ball 35 can be squeezed into the inside of the storage groove 32, so that the bottom plate 1 contacts the slope, thereby ensuring the stability of the device. The setting of the walking mechanism improves the convenience of the device's movement and does not affect the stability of the device during the measurement process.
