Under the condition without changing the generator body, the turbine generator changes the high-speed torque to low-speed torque, and can be suitable for the gas drilling.

Description

A kind of turbogenerator that is used for gas drilling
Technical field
The utility model relates to a kind of generator, especially a kind of turbogenerator that is used for gas drilling.
Background technique
Mud turbine generator is as the important component part of down-hole with the brill instrument, be widely used in the DWM field, but in gas drilling, because the driven medium density of wind generator turbines obviously reduces, the torque limit that is directly provided by turbine rotor is very little, existing mud turbine generator is difficult to drive generator rotor shaft, therefore, is not suitable for gas drilling.
Summary of the invention
Little in order to overcome existing turbogenerator moment of torsion, be not suitable for the deficiency of gas drilling, the utility model provides a kind of turbogenerator that is used for gas drilling, this turbogenerator is under the situation that does not change the generator body, high speed low torque is become low speed and large torque, can be applicable to gas drilling.
The technical solution of the utility model is: a kind of turbogenerator that is used for gas drilling, comprise Coupler rotor, turbine rotor and inner turbine rotor shaft thereof, the lower end of described turbine rotor shaft connects the input shaft of speed reducer, the output shaft of speed reducer is connected with shift fork, there is pusher dog described shift fork lower end, pusher dog matches with the groove of magnetic coupler outer cover outside, and described magnetic coupler outer cover places the Coupler rotor exterior.
The utlity model has following beneficial effect: owing to take such scheme, speed reducer and shift fork have been increased between turbine rotor and the Coupler rotor, by speed reducer the low torque axis of the high rotating speed of turbine rotor output shaft is become the high moment of torsion of the slow-speed of revolution, thereby driving generator amature rotates, avoided change generator output circuit, and made it can adapt to the special requirement of gas drilling.

Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, shown in Figure 3, a kind of turbogenerator that is used for gas drilling, comprise Coupler rotor 1, turbine rotor 14 and inner turbine rotor shaft 15 thereof, the lower end of described turbine rotor shaft 15 connects the input shaft of speed reducer 16 by flat key, the output shaft of speed reducer 16 is connected with shift fork 17 by flat key equally, there is pusher dog 170 described shift fork 17 lower ends, pusher dog 170 is two of symmetrical distribution, magnetic coupler outer cover 19 outsides have the groove of two symmetrical distributions equally, pusher dog 170 matches with groove, and described magnetic coupler outer cover 19 places Coupler rotor 1 outside.Owing between turbine rotor 14 and generator rotor shaft 3, installed speed reducer 16 additional, utilize the mode of mechanical reduction to reach the purpose that reduces rotating speed raising torque, when speed reducer 16 drives shift fork 17 rotations, drive magnetic coupler outer cover 19 by pusher dog 170 and rotate, finally the rotation of turbine rotor 14 is exported and pass to generator rotor shaft 3 by magnetic-coupled mode.
The top of turbine rotor 14 has water conservancy diversion stator 13 to be fixed on turbine rotor shaft 15 outsides; stable axial gas enters water conservancy diversion stator 13; water conservancy diversion post acceleration through water conservancy diversion stator 13; direction impulse turbine rotor 14 with vertical turbine rotor 14 blades; because the turbine of high speed rotating can 11 inwalls produce big erosion to boring very; therefore endure to install additional in 11 at brill and bore very protecting jacket 12; be fixed in by high strength pin 20 and bore very 11 inwalls, bore and to unload pin 20 after very protecting jacket 12 wearing and tearing and change.Magnet rotor 18 outside magnetic coupling outer cover 19 inside are equipped with, outer magnet rotor 18 inside are magnetism shielding hood 2, magnetism shielding hood 2 adopts nonmagnetic titanium alloy or aluminum alloy to make, and non-contact type magnetic coupling transmission means has promptly reduced sealing part, has increased the reliability of energy transfer under the vibration situation again.There is Coupler rotor 1 magnetism shielding hood 2 inside; Coupler rotor 1 is fixed on the generator rotor shaft 3; by non-contact type magnetic coupling transmission means transmission runner torque; interior magnet rotor 1 is formed by the permanent magnet sintering with the magnetic sheet of outer magnet rotor 18, and magnetic sheet N, S utmost point arranged alternate round, in inside and outside magnetic sheet process is installed; even full-filling 705 silica gel are located in the magnetic sheet slit; both played bonding magnetic sheet effect, and can bring damping effect again, integral body is inserted in the magnetic sheet protecting jacket then.
Fig. 2 is mine gas turbogenerator main body structure figure, the deep groove ball bearing at generator rotor shaft 3 two ends is individually fixed among its corresponding upper bearing bracket 5 and the step 8, the mode that bearing support adopts shift fork to connect is fixing with generator unit stator 6, make generator unit stator 6 like this, generator amature 7 and upper bearing bracket 5, step 8 becomes integral body, by the flat key Placement integral body and outer resistance to compression shell 10 are fixed then, between upper bearing bracket 5 and magnetism shielding hood 2, be provided with beam 4, be provided with down beam 9 between step 8 and the pressure-proof outer cover 10, can reduce instrument axial vibration, absorb the most of vibration of generator body.
The utility model is base of design with the mud turbine generator, under the prerequisite that does not change the generator output circuit, for turbine drives partly increases reducing gear, increase the turbine output torque, design and in gas drilling, can produce the high-power turbo generator consistent with output power in the mud well.Simultaneously, exploitation multi-series mine gas drives turbine assembly, when the mine gas flow changes or places the drill collar variation of generator body, changes and drives turbine assembly, has so further widened its using scope.
