Abstract: Provided is a two-stage reverse-torque bent screw orientation tool. An existing bent screw orientation technology has the technical problems of large friction resistance, difficult control of a borehole track, a low drilling speed and the like, and restricts economic, safe and long-acting development of oil and gas. In order to solve the above problems, the two-stage reverse-torque bent screw orientation tool is invented and composed of a first-stage clutch mechanism and a second-stage clutch mechanism, and the first-stage clutch mechanism and the second-stage clutch mechanism are both composed of a battery, a battery compartment, a pressure sensor, an electromagnetic valve, a body, a plug, a piston, an outer tooth cylinder, an inner tooth cylinder, a transmission cylinder, a connecting cylinder, a bearing, a limiting cylinder, a lower joint, a thrust bearing, a battery compartment, a circuit board, a cover plate and the like.

Abstract: The present invention discloses an automatic removing apparatus for ring main unit cable head which comprises an outer casing formed by a handle and an outer casing body; the outer casing body has a rear end which is fixedly connected to the handle; the outer casing body has a front end which is fixedly connected to a connecting head; a motor and a control chip connected to the motor are disposed inside the outer casing; the control chip is electrically connected to a battery for supplying power to the control chip and the motor; the motor has a rotation shaft which drives rotation of a main gear; the connecting head is fixedly connected to a removing rod; a follower gear which meshes with the main gear is fixedly disposed at the connecting head for rotating around the main gear. The present invention has the advantageous effect of enhancing working efficiency.
