Recyclable inclination measuring device with z-shaped arrangement
The granted patent (Publication Number: US12000712B1) discloses a recyclable inclination measuring device designed with a unique configuration. The device comprises measuring units arranged in a linear array during installation, with two adjacent units eccentrically hinged by a joint. During measurement, the units are arranged in a Z shape within a measuring tube, with the inner wall of the tube closely attached to the joint. The joint includes both flexible and rigid hinge joints arranged symmetrically, with right-angled triangular structures. Each measuring unit also includes a rigid rod, with a three-axis acceleration sensor positioned in the middle of the rod through a packaging box.
Furthermore, the patent details the connection of the acceleration sensor to an outlet cable, which is then linked to the packaging box and joint. The device ensures a secure fit with the inner wall of the rigid rod through interference fit for both the flexible and rigid hinge joints. Additionally, the three-axis acceleration sensor is waterproofed with an IP68 rating, enhancing its durability and functionality in various environmental conditions. Overall, the patented recyclable inclination measuring device offers a novel design with a focus on precision, reliability, and environmental sustainability through its recyclable components and waterproof features.
