Description

Technical Field

[0001] The utility model belongs to the technical field of inclinometers, and in particular relates to a fixed inclinometer device. Background Art

[0002] A fixed inclinometer is an instrument used to detect the tilt or deformation of structures (such as dams, slopes, tunnels, etc.). It can provide accurate horizontal displacement, vertical settlement and landslide data, thereby helping engineers assess the stability and safety of the structure.

[0003] First, engineers drill a hole near the test point and then place an inclinometer into the hole for measurement. However, if the engineer uses a handheld inclinometer, factors such as human movement and vision may prevent the inclinometer from being perpendicular to the ground before insertion. This can cause the measurement results to inaccurately reflect the actual tilt due to systematic errors. Furthermore, during the inclinometer placement process, the engineer must operate slowly, otherwise the inclinometer will shift in the hole, resulting in measurement errors and even damage. Therefore, a fixed inclinometer device is needed to solve the above problems. Utility Model Content

[0026] Inclinometer body 1;

[0027] A mounting frame 2, the inclinometer body 1 is mounted on the mounting frame 2, and a threaded hole 21 is formed on the upper surface of the mounting frame 2;

[0028] The calibration assembly 3 includes an adjustment column 31, a support column 32, a fixing screw 33, and a level 34. One end of the adjustment column 31 is rotatably mounted on the lower surface of the mounting frame 2. The support column 32 is threadedly connected to the other end of the adjustment column 31. Two fixing screws 33 are provided. The two fixing screws 33 are rotatably mounted in the threaded holes 21 relative to each other. The level 34 is mounted on the mounting frame 2.

[0029] Insert component 4, which is installed on mounting frame 2;

[0030] The insertion assembly 4 includes a fixed pulley 41, a movable pulley 42, and a traction rope 43. The mounting frame 2 also includes a fixed shaft 22. The fixed pulley 41 is mounted on the top of the mounting frame 2, and the movable pulley 42 is mounted on the top of the inclinometer body 1. The fixed shaft 22 and the fixed pulley 41 are arranged on the same horizontal plane. One end of the traction rope 43 is fixed to the fixed shaft 22. The traction rope 43 is wrapped around the fixed pulley 41 from top to bottom, and the traction rope 43 is wrapped around the movable pulley 42 from bottom to top.

[0031] The insertion assembly 4 further includes a rotating motor 44 mounted on the mounting frame 2. The mounting frame 2 further includes a rotating shaft 23 disposed below the fixed shaft 22. One end of the traction rope 43 away from the fixed shaft 22 is fixedly connected to the rotating shaft 23. The output shaft of the rotating motor 44 is connected to the rotating shaft 23.

[0032] The inclinometer body 1 includes a guide wheel 11, a movable column 12, a return spring 13, and a movable groove 14 for sliding the movable column 12. The guide wheel 11 is rotatably mounted on one end of the movable column 12. The return spring 13 is connected to the other end of the movable column 12 and the inner wall of the movable groove 14. Two guide wheels 11 are provided, and the two guide wheels 11 are symmetrically distributed around the movable pulley 42.

[0033] The support column 32 has a support plate 321 at one end away from the adjustment column 31, and the cross section of the support plate 321 is set to be circular;

[0034] The upper end of the fixing screw 33 has a rotating handle 331 , and the lower end of the fixing screw 33 has a fixing plate 332 . The cross section of the fixing plate 332 is set to be circular.

[0035] The working principle and use process of this utility model:

[0036] First, the engineer places the support plate 321 on the ground at the test point and observes the level 34. The engineer rotates the support column 32 to adjust the height of the mounting frame 2 relative to the ground, and simultaneously rotates the adjustment column 31 to adjust the inclination of the mounting frame 2 relative to the ground until the level 34 indicates that the mounting frame 2 is horizontal relative to the ground. The engineer then rotates the fixing screw 33 by turning the handle 331 to fully contact the fixing plate 332 with the ground, preventing the mounting frame 2 from tilting again after the adjustment. This ensures that the inclinometer body 1 is perpendicular to the ground before being placed in the borehole, reducing the possibility of measurement results being affected by systematic errors.

[0037] After the mounting frame 2 is horizontal relative to the ground, the rotating motor 44 drives the rotating shaft 23 to rotate, so that the traction rope 43 wound around the rotating shaft 23 is gradually detached, and the fixed pulley 41 and the movable pulley 42 surrounded by the traction rope 43 rotate accordingly, thereby driving the inclinometer body 1 connected to the movable pulley 42 to gradually move downward, thereby preventing the inclinometer body 1 from moving downward too quickly and causing deviation in the borehole or damage to the inclinometer body 1, further reducing measurement errors;

[0038] After the inclinometer body 1 is placed in the borehole, the guide wheel 11 slides along the side wall of the borehole, driving the movable column 12 to slide in the movable groove 14 toward the direction close to the return spring 13. At this time, the return spring 13 is compressed. By providing the return spring 13, after the test is completed, the inclinometer body 1 is separated from the borehole, and under the action of the return spring 13, the movable column 12 and the guide wheel 11 return to their original positions.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
