Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering monitoring, in particular to an inclinometer. Background Art

[0002] Inclinometer is an instrument used to measure the top angle and azimuth of engineering structures such as boreholes, foundation pits, foundations, walls and dam slopes. The horizontal displacement is obtained by measuring the inclination angle of the borehole. In specific engineering applications, the inclinometer tube is first embedded in the soil (pile body). After the soil (pile body) is deformed, the entire inclinometer tube also deforms accordingly. The inclinometer pulley is tested point by point along the groove, so that the horizontal displacement can be accurately measured. According to the size of the displacement, a forecast is made to guide the construction. Inclinometers are widely used in the fields of water conservancy and hydropower, mining and metallurgy, transportation and urban construction geotechnical engineering, and play an important role in ensuring the design, construction and safety of geotechnical engineering.

[0003] At present, Chinese patent publication number: CN219608014U discloses an inclinometer pulley mechanism. In the public document, the pulley block mechanism is located at one side of the connecting rod and is rotatably connected to the connecting rod. Therefore, when the inclinometer is inserted into the inclinometer tube, the inner wall of the inclinometer tube will squeeze the pulley block mechanism to make the pulley block mechanism rotate relative to the connecting rod. Since the pulley block mechanism is rotatably connected to the connecting rod by only one side, it is easy to cause the pulley block mechanism to be eccentric, that is, the pulley block mechanism and the connecting rod are easily stuck, that is, it is impossible to ensure that the pulley block mechanism rotates smoothly relative to the connecting rod. In addition, there is a disadvantage that the rotation reliability of the pulley block mechanism and the connecting rod is poor. Utility Model Content
