Abstract

The invention discloses a mud turbine generator of an automatic vertical drilling tool. The mud turbine generator comprises a generation structure, a front oil chamber supporting mechanism and a rear oil chamber compensating mechanism. According to the generation structure, an inner permanent magnet is arranged on the outer circle of the middle of a motor shaft in a sleeving mode; an outer permanent magnet is fixed to the inner permanent magnet; an outer motor cylinder is arranged outside the outer permanent magnet in a sleeving mode; and a turbine is connected to the outer circle of the outer motor cylinder in a buckled mode. A four-core high-pressure seal and a multi-core high-pressure seal are installed at the upper end and the lower end of the motor shaft respectively. According to the front oil chamber supporting mechanism, a sealing cap, an adjusting piece, a thrust bearing, a locating sleeve and a deep groove ball bearing I are sequentially installed on the upper part of the motor shaft from top to bottom in a sleeving mode. According to the rear oil chamber compensating mechanism, a deep groove ball bearing II, a piston and a compensation spring are sequentially installed on the periphery of the lower part of the motor shaft from top to bottom in a sleeving mode. According to the invention, underground normal work of the tool can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electromechanical equipment, and relates to a mud turbine generator for an automatic vertical drilling tool. Background technique [0002] The push-out and contraction of the thrust plate of the actuator of the existing "vertical drilling tool" mainly depends on the solenoid valve or the electric motor to control the hydraulic device, and the electric power of the solenoid valve and the electric motor is mainly through the battery installed in the power supply compartment or the non-contact power transmission device supply. Due to the limited power of the battery and the large reluctance of the non-contact power transmission device, the power supply efficiency is low. These two power supply modes restrict the operating efficiency of vertical drilling tools and do not meet the needs of oilfield drilling to increase the speed and efficiency. [0003] Develop a new type of mud turbine generator, which can n...
