Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of inclinometer, more particularly, relate to a portable inclinometer. BACKGROUND

[0002] An inclinometer is a professional instrument used to measure the inclination and displacement changes of engineering structures such as boreholes, foundation pits, foundations, walls, and dam slopes. It plays a crucial role in geotechnical engineering monitoring, allowing for the assessment of geological hazard risks, monitoring of building structural safety, and ensuring the safe and stable operation of various engineering projects. The inclinometer senses changes in inclination angle through internal sensors such as resistance strain gauges, vibrating wire sensors, or accelerometers, and calculates the displacement in the horizontal direction accordingly. The inclinometer is usually installed in a vertical inclinometer tube that passes through unstable soil layers to reach the lower stable stratum. As the inclinometer probe moves up and down within the inclinometer tube, it can measure inclination data at different depths. Based on these data, the horizontal displacement of each depth point can be determined, and the stability of the entire structure or region can be inferred.

[0003] In the prior art, a new full-automatic geotechnical inclinometer is disclosed in Chinese patent application CN115031688A, which includes: an inclinometer body; a lifting device; a rotating device; an inclinometer probe; an upper measuring tube; a plurality of dry reed tubes, which are arranged in the lower measuring tube along the length direction of the lower measuring tube, wherein each dry reed tube is electrically connected with the inclinometer body; wherein a magnetic ring is arranged in the inclinometer probe, when the inclinometer probe with the magnetic ring moves to the position of the dry reed tube, the dry reed tube is closed, the inclinometer body obtains the position of the dry reed tube, and a control instruction is generated to the inclinometer probe, so that the inclinometer probe automatically collects data according to the control instruction. Chinese patent CN219950111U discloses an automatic inclinometer for reducing cable wear, relating to the technical field of inclinometers, which includes: a housing; a rotating support rotatably connected inside the housing; a wire winding drum slidingly installed on the outer peripheral surface of the rotating support; a metering roller rotatably installed at the lower end of the top plate; a wire winding power motor fixedly connected to the inner side of the first side plate; a conductive slip ring arranged inside the rotating support away from the wire winding power motor; a fixed gear fixedly connected to the inner side of the second side plate; a rotating gear with its axis fixedly connected to one end of the reciprocating lead screw extending to the outside of the rotating support, the rotating gear and the fixed gear are meshed with each other.

[0004] While the aforementioned patents have made some improvements to the performance and practicality of traditional inclinometers, the design of traditional inclinometers prioritizes measurement accuracy and stability over portability, resulting in numerous internal mechanical and electronic components, increasing their size and weight. Secondly, to improve stability, some components, especially the outer casing and internal supports, are often made of metal or other materials for robustness and durability, further increasing the overall weight. Furthermore, during long-term monitoring, energy demands are high, and many inclinometers rely on external power sources (such as high-capacity battery packs) for operation, further increasing the overall weight. These factors significantly reduce the flexibility of the overall inclinometer system, directly impacting work efficiency, hindering efficient deployment and operation in various environments, potentially delaying response times in emergencies, and also increasing project costs and limiting the scope of application.
