Description

Technical Field

[0001] This utility model relates to the field of inclinometer technology, and in particular to a fiber optic inclinometer. Background Technology

[0002] In operation, fiber optic inclinometers typically use a clinometer tube installed in a vertical borehole penetrating from an unstable soil layer to a lower, stable stratum. A digital vertical moving inclinometer probe, control cable, pulley system, and readout unit are used to observe the deformation of the clinometer tube. During observation, the probe moves from the bottom to the top of the clinometer tube, pausing at a half-meter interval to measure the tilt. The probe's tilt is measured by two force-balanced servo accelerometers. As the probe moves within the clinometer tube, friction between the probe's connecting cable and the tube can easily cause damage. For example, a fiber optic gyroscope inclinometer (patent CN221781554U) uses a protective cover, mounting block, limiting plate, mounting groove, and spring 2 to buffer the impact force on the probe through the counterforce of spring 2. While this protects the probe, the lack of cable protection means the cable can collide with the clinometer tube during movement, potentially damaging the cable and causing vibrations that affect the probe's detection. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fiber optic inclinometer.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a fiber optic inclinometer, including a control box. The control box is connected to a measuring rod via a cable. The measuring rod passes through a mounting bracket. Telescopic brackets are vertically installed at the four corners of the bottom of the mounting bracket. The measuring rod is inserted into the inner cavity of a measuring tube. An installation groove is formed on the outer wall of the measuring rod. A roller is rolled in the installation groove via a roller bracket. The roller contacts the inner wall of the measuring tube. A pair of movable brackets overlap on the mounting bracket. A sliding bearing is sleeved on the outer wall of the cable and overlaps the movable brackets.

[0006] Preferably, the telescopic bracket is a threaded telescopic structure, including a support rod connected to the mounting bracket, and a threaded sleeve at the bottom of the support rod.

[0007] Preferably, the movable support is conical, and a pair of movable supports can rotate through a hinge.

[0008] Preferably, a pressing handle is welded to the upper end face of a pair of movable supports, and the pressing handle is distributed on both sides of the hinge.

[0009] Preferably, there are multiple mounting slots, which are staggered on the measuring rod.

[0010] Preferably, the bottom of the measuring rod is threaded with a rubber cap.

[0011] Preferably, the sliding bearing has multiple balls in its inner cavity, and the movable support of the sliding bearing has an adsorption magnet on its outer wall, and the movable support is magnetically connected to the sliding bearing.

[0012] The fiber optic inclinometer proposed in this utility model has the following advantages: by setting a telescopic bracket to adjust the height of the mounting bracket, the mounting bracket can adapt to the height of the measuring tube in the field and be adjusted to a suitable height according to different terrains, thereby improving the stability of equipment operation. The movable bracket is set to lock the sliding bearing, and the cable passes through the sliding bearing and contacts the ball bearing inside the sliding bearing, reducing wear on the cable. At the same time, it can reduce the shaking generated when the cable moves up and down, thereby improving the measurement accuracy of the measuring rod. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1 , 23. A fiber optic inclinometer includes a control box 1. The control box 1 is connected to a measuring rod 9 via a cable 2. The measuring rod 9 passes through a mounting bracket 3. Telescopic brackets 4 are vertically installed at the four corners of the bottom of the mounting bracket 3. The measuring rod 9 is inserted into the inner cavity of a measuring tube 8. An installation groove 11 is provided on the outer wall of the measuring rod 9. A roller 13 is rolled in the installation groove 11 via a roller bracket 14. The roller 13 facilitates the smooth movement of the measuring rod 9. The roller 13 contacts the inner wall of the measuring tube 8. A pair of movable brackets 7 are attached to the mounting bracket 3. A sliding bearing 12 is sleeved on the outer wall of the cable 2 and is attached to the movable brackets 7.

[0021] Reference Figure 2 The telescopic bracket 4 is a threaded telescopic structure, including a support rod connected to the mounting bracket 3. The bottom of the support rod is threadedly connected to a sleeve, which allows the height of the mounting bracket 3 to be adjusted to adapt to the height of the measuring tube 8 in the site. It can also be adjusted to a suitable height according to different terrains to improve the stability of equipment operation. The movable bracket 7 is conical. A pair of movable brackets 7 can rotate through a hinge 6. The upper end face of a pair of movable brackets 7 is welded with a pressing handle 5, which is distributed on both sides of the hinge 6. The hinge 6 allows the pair of movable brackets 7 to open and close. When the pair of movable brackets 7 are separated, the measuring rod 9 passes through the mounting bracket 3, and then the pressing handle 5 is oscillated to close the pair of movable brackets 7. At this time, the sliding bearing 12 is attracted to the bottom of the inner cavity of the movable bracket 7, which reduces the wear and shaking of the cable 2 when it is moved up and down.
