Background technology
The powerup issue for solving the downhole instruments such as rotary steering instrument at present is mainly come real by turbogenerator power generation
Existing.General turbogenerator, is limited by installation space, and the impeller size of generator is also restricted, therefore sends out
The power of motor must not be promoted.Particularly in the case where providing power for static pushing type rotary steering instrument, generator
Electric power need that rotary sleeve does not transmit from axial rotary, power transmission efficiency and power at this moment all can reduce greatly, and long
Phase is in generator under the working environment that mud washes away and is also easily damaged, and reduces service life.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of embedded generator of underground rotary steering instrument,
Stator rotor is embedded in instrument body, using mud as power.Generator electrical is directly output to not rotary sleeve, is met with this
The demand of rotary steering equipment power transmission during the use of underground, improves generator power and efficiency.
The utility model is realized in this way a kind of embedded generator of underground rotary steering instrument, including being fixed to rotation
The blade of guide instrument interior of rotating shaft, rotor assembly and it is embedded into stator coil winding of the guide instrument not in rotary sleeve, blade,
Rotor assembly includes blade, blade bearing, rotor field spider and permanent magnet, and blade bearing is mounted in rotary steering instrument rotary shaft
Blade is rotatably mounted to interior of rotating shaft center, blade bearing connection rotor field spider by wall, and rotor field spider embeds permanent magnetism
Body, blade rotation drive rotor field spider and permanent magnet rotating, form variation magnetic field, and stator coil winding cutting magnetic induction line generates
Electric current.
Further, the blade installation number can adjust, clearance fit installation.
Further, the blade, rotor assembly further include blade bearing block and generator amature protective layer, blade bearing
Seat is fixed on the rotary shaft inner wall, and the blade bearing is installed in blade bearing block, is set among the blade and rotor field spider
Put generator amature protective layer.
Further, the stator coil winding has multiple, is evenly distributed on the not rotary sleeve peripheral wall.
Compared with prior art, the utility model has the advantage of：
1st, due to adding adjustable blade, the power generation work(of generator can be improved or kept according to drilling environment difference
Rate.
2nd, the electric power sent out directly feeds the electronic device in not rotary sleeve, avoids coupling transformer transmission electric power timeliness
The problem of rate is low.
3rd, by generator embedded rotating guide instrument, reduce the entire length of rotary steering instrument.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment is described in further detail the utility model：
Fig. 1 is the utility model main view cross-sectional view；
Fig. 2 is the utility model side elevational cross-section structure diagram.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
With reference to figure 1 and Fig. 2, the utility model provides a kind of embedded generator of underground rotary steering instrument, including fixation
Blade, rotor assembly inside to rotary steering instrument rotary shaft 6 and be embedded into guide instrument not the stator coil in rotary sleeve 7 around
Group 1, blade, rotor assembly include blade 2, blade bearing 3, rotor field spider 4 and permanent magnet 5, and blade bearing 3 is mounted on rotation and leads
To 6 inner wall of instrument rotary shaft, blade 2 is rotatably mounted to 6 inside center of rotary shaft, blade bearing 3 connects rotor field spider 4,
Rotor field spider 4 embeds permanent magnet 5, and the rotation of blade 2 drives rotor field spider 4 and permanent magnet 5 to rotate, forms variation magnetic field, stator line
1 cutting magnetic induction line of winding is enclosed, generates electric current.
The utility model insertion is mounted in rotary steering instrument, during work, mud stream crosses 6 center of rotary shaft, drives paddle
Leaf 2 rotates, and blade 2 drives blade bearing 3, rotor field spider 4 and permanent magnet 5 to rotate, and variation magnetic field is formd, not in rotary sleeve 7
1 cutting magnetic induction line of stator coil winding, generate electric current, electric current directly feed gives rotary steering instrument use.
As the improvement of technical solution, 2 installation number of blade can adjust, clearance fit installation.When mud pumpage is not up to
To requirement when, electrical power generators power cannot improve, and can be required according to different mud displacements, adjust generator blade ring
Shape area further enhances the working efficiency of running wheel, and then improves the generated output of generator.
For preferably fixed blades and permanent magnet is protected, as the improvement of technical solution, blade, rotor set
Part further includes blade bearing block 8 and generator amature protective layer 9, and blade bearing block 8 is fixed on 6 inner wall of rotary shaft, blade bearing
Setting generator amature protective layer 9 among the installation blade bearing 3 in seat 8, blade 2 and rotor field spider 4.
For preferably cutting magnetic induction line, as the improvement of technical solution, stator coil winding 1 has multiple, is uniformly distributed
On 7 peripheral wall of not rotary sleeve.
