| titleOfInvention | Inclination tester and method based on spherical cavity mercury reflection |
| abstract | The invention relates to the technical field of angle detection, in particular to an inclination tester and a test method based on mercury reflection of a spherical cavity, wherein the tester comprises a signal acquisition module, a signal conditioning module and a control module; the signal acquisition module comprises a shell and a test ball arranged in the shell, the test ball comprises an inner spherical surface, an outer spherical surface, a first fixing shaft and a second fixing shaft, the inner spherical surface and the outer spherical surface are concentrically arranged, the outer wall of the inner spherical surface is provided with light receivers, and each light receiver comprises a light-emitting diode and a light-sensitive tube for collecting light; the outer wall of the inner spherical surface and the inner wall of the outer spherical surface are both coated with black light absorption materials; a gap cavity is formed between the inner spherical surface and the outer spherical surface, mercury is injected into the lower part in the gap cavity, and the circle surface boundary of the mercury surface pointing to the sphere center is parallel to the circumscribed circle of the area where the light receiver is located and has the same size; the signal conditioning module is used for conditioning the electric signal converted from the optical signal collected by the photosensitive tube; the control module is used for the tilt angle calculation. The invention realizes the calculation and detection of the inclination angle. |
