Title:
DEVICE FOR COLLECTING MOVEMENT TRAJECTORY OF ORE ROCK IN MINE BLASTING
Document Type and Number:
WIPO Patent Application WO/2024/060533
Kind Code:
A1
Abstract:
The present invention provides a device for collecting a movement trajectory of ore rock in mine blasting, comprising: a spherical explosion-proof shell having an opening in one surface; an explosion-proof cover in fit connection to the opening; a self-stabilizing device provided in the spherical explosion-proof shell, wherein the self-stabilizing device comprises: an outer circular ring, a middle circular ring, an inner circular recess, and slots, the middle circular ring is movably connected to the interior of the outer circular ring by means of a first bearing and a second bearing that are collinear and located on an X-axis, the inner circular recess is movably connected to the interior of the middle circular ring by means of a third bearing and a fourth bearing that are collinear and located on a Y-axis, and the X-axis and the Y-axis are perpendicular to each other; and an inertial navigation sensor for mine blasting fixed in the inner circular recess by means of the slots in the inner circular recess. The device for collecting a movement trajectory of ore rock in mine blasting of the present invention can always maintain a horizontal posture in a blasting process without being affected by a blasting site environment and the blasting process, and internal precise instruments are protected from being damaged by impact force generated in the blasting process.
