Description
Technical field
The utility model relates to unmanned plane, particularly a kind of device supporting the anti-twisted power of main rotor in the middle of oil electricity mixing plant protection unmanned plane.
Background technology
The anti-twisted power that many rotors produce when flying is rotating speed by controlling each rotor and is formed to be arranged symmetrically with by each rotor and offset.Specifically: relative gyroplane rotate speed is identical, adjacent gyroplane rotate speed is contrary, and the anti-twisted power that each rotor produces is cancelled out each other just.
The anti-twisted power that helicopter produces time in fashion produces rightabout moment to balance by arranging an empennage.Specifically: a part of power of intermediate conveyor screw oar is transferred to empennage portion by V belt translation, make the plane of rotation of empennage mutually vertical with the plane of rotation of intermediate conveyor screw oar, the counter torque that such empennage produces just can offset the anti-twisted power that intermediate conveyor screw oar produces.
Applicant has applied for that china national practical new-type patent " new oil moves many rotors plant protection unmanned plane " application number is on this basis: 201520335089.7, helicopter and many rotors combine by it, the unmanned plane of this structure is other in many rotor wing unmanned aerial vehicles, here rotor does not provide power, the only adjustment of responsible attitude, very low to the requirements for quality of rotor, even if any one rotor breaks down also can not cause air crash, traditional many rotor wing unmanned aerial vehicles are not then.This unmanned plane of applicant devises rudder face on rotor arm, the contrary feature of identical relative to the second propeller turning direction, adjacent second propeller turning direction in diagonal angle and this rudder face cooperation is utilized to balance the anti-twisted power of the first screw propeller, and the utility model is removing its rudder face, inventing a kind of novel and effectively can to offset the device of the anti-twisted power of main rotor.
Utility model content
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of device supporting the anti-twisted power of main rotor in the middle of oil electricity mixing plant protection unmanned plane, its can actv. offset main rotor produce anti-twisted power, and it is easy to assemble and folding, save electric energy, improve flying power.
The technical solution of the utility model is, comprise rotor arm, one end first motor of rotor arm is equipped with the second rotor, described rotor arm is equipped with the pipe link that one end of the second rotor is equipped with rotatably, is located and dismantle, the free end of pipe link is equipped with the thruster towards the anti-twisted force direction of unmanned plane main rotor.
Advantage of the present utility model:
1, the utility model structure is simple, and tooling cost is low, and easy installation and removal;
2, angle is arranged rationally, can offset the anti-twisted power that middle main rotor produces completely, and it is convenient to control;
3, the inner secure and reliable connection of device, can well resist mechanical vibration in flight course, after flight terminates, device is easy to fold, and after folding, volume-diminished is a lot, is convenient to place and transport;
4, after this device launches, rotor arm lengthens a lot, and like this on equal conditions, the electrode on rotor arm provides relatively little power just can meet the lift demand of complete machine, so just can save electric energy, improves the flying power of complete machine.

Fig. 1 is the main TV structure figure of the utility model;
Fig. 2 is the A direction view of thruster part in the utility model;
Fig. 3 is the schematic diagram that the medium and small rotor of the utility model offsets the anti-twisted power of main rotor.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, the utility model comprises rotor arm 1, one end first motor 6 of rotor arm 1 is equipped with the second rotor 2, described rotor arm 1 is equipped with the pipe link 3 that one end of the second rotor 2 is equipped with rotatably, is located and dismantle, the free end of pipe link 3 is equipped with the thruster towards the anti-twisted force direction of unmanned plane main rotor.
Described thruster comprises the second motor 4 being arranged on pipe link 3 free end and the little rotor 5 installed towards the anti-twisted force direction of unmanned plane main rotor.
Described rotor arm 1 comprises rotatable on the first cantilever 101, first cantilever 101 free end of being arranged in unmanned plane main body, location and the second cantilever 102 is equipped with in dismounting, and the free end of described second cantilever 102 is provided with the second rotor 2 through the first motor 6.
The free end of described second cantilever 102 is the angle installation pipe link 3 of 120 °-160 °.Angle, as θ in figure 2, prevents the second rotor 2 from occurring crossover phenomenon with little rotor 5 plane of rotation.
Described first cantilever 101 installs the second cantilever 102 in 130 °-170 ° obliquely.Angle just can be very high as θ in figure 3 lifting flight course in stationarity, be convenient to regulate the flight attitude of complete machine simultaneously, allow complete machine fly to control more flexible.
The plane of rotation of described little rotor 5 and the symmetrical plane angle of unmanned plane complete machine are 1 °-6 °.Angle, as θ in figure 1, so just can provide enough anti-twisted power for unmanned plane complete machine, allows aircraft smooth flight.
The one end of described rotor arm 1 being equipped with the second rotor 2 is connected through bolt and nut 7 with pipe link 3, forms the structure of rotatable, location and dismounting.
Described first cantilever 101 connects the second cantilever 102 through bolt and nut 7, forms structure that is rotatable, that locate and dismantle.
The utility model first the utility model be applicable to applicant application china national practical new-type patent " new oil moves many rotors plant protection unmanned plane " application number be: 201520335089.7, such unmanned plane be the respective advantage of many rotors and helicopter is integrated after the new unmanned plane type of one that formed, such unmanned plane is different from the many rotors and helicopter that occur in the market, therefore the counteracting of anti-twisted power can not indiscriminately imitate the method for many rotors and helicopter, in order to overcome the anti-twisted power of main rotor in the middle of this novel unmanned plane, we have employed device of the present utility model.
