| description | The invention discloses an automatic monitoring device for a geological core drilling parameter hole bottom. The device comprises a measuring short section body, a power module and a hole bottom drilling parameter measuring module. The upper end of the measuring short section body is connected with a drill rod, the lower end of the measuring short section body is connected with a drill bit, the interior of the measuring short section body is hollow, and a measuring groove is formed in the outer wall of the measuring short section body. The hole bottom drilling parameter measuring module is sealed in the measuring groove and comprises at least one of a hole inclination module, a rotating speed module, a temperature module, a drilling pressure and torque module, an outer annulus pressure module and an inner annulus pressure module. The hole inclination module, the rotating speed module, the temperature module, the drilling pressure and torque module, the outer annulus pressure module and the inner annulus press |
