Power generation facility for unmanned aerial vehicle includes
A support 10; the support 10 is fixedly connected to the main body of the drone and is used to provide support and location for the generator 20.
A generator 20; the stator 22 of the generator 20 is fixedly connected to the bracket 10 through a generator bracket 23; the preferred generator 20 of this application is the engine of outer rotor structure, and its magnet of this kind of structure's generator is located the coil outside, and the generator heat dispersion of this kind of structure is better, and length is shorter.
A transmission shaft 30; the transmission shaft 30 is connected to the rotor 21 of the motor 20 through a one-way transmission assembly, and transmission is performed between the transmission shaft 30 and the rotor 21 if and only if the transmission shaft 30 rotates in a forward direction with respect to the rotor 21. The unidirectional transmission assembly is arranged between the transmission shaft and the generator rotor, the generator is driven to generate electricity in the normal running process of the engine, and meanwhile, the engine rotor is timely separated from the transmission shaft after the engine stalls and stops rotating; the reason why the engine rotor is separated from the transmission shaft when the engine stalls and stops rotating is that the engine drives the generator rotor to rotate at a high speed, so that the engine rotor still has high inertia when the engine stalls and stops rotating, and if the engine rotor and the generator rotor are not separated, the inertia of the generator rotor can possibly drive the main shaft of the engine to rotate so as to generate large impact on the main shaft of the engine and even cause damage to the main shaft of the engine, so that the unidirectional transmission assembly is arranged to avoid the problem; specifically, a transmission shaft channel is formed in the support 10, a bearing 40 is installed in the transmission shaft channel, and the transmission shaft 30 is assembled with the bearing so that the transmission shaft 30 rotates. The unidirectional transmission assembly comprises a unidirectional bearing 32 and a connecting piece 33, a shaft sleeve of the unidirectional bearing 32 is fixedly connected to the transmission shaft 30, one end of the connecting piece 33 is inserted into the unidirectional bearing 32 and matched with the unidirectional bearing 32, and the other end of the connecting piece is connected with the rotor 21. A mounting hole 331 is formed at one end of the connecting member 33 away from the one-way bearing 32, and a rotating shaft of the rotor 21 is embedded in the mounting hole 331. Because of the working principle of the one-way bearing, the hardness requirement of the shaft surface which is inserted into the inner hole of the one-way bearing and is contacted with the needle roller of the one-way bearing is higher, and because the impact between the needle roller and the shaft surface is larger in the combination process, the surface of the shaft is easy to be scratched, so that the problem of one-way transmission slip is easily caused; if the rotating shaft of the generator rotor is directly matched with the one-way bearing, the rotating shaft is worn, and the whole engine needs to be replaced, so that the maintenance cost is high. Thus, the design of the connecting piece 33 completely solves the problem, and after the connecting piece 33 is worn, only the connecting piece 33 needs to be replaced, so that the maintenance cost is greatly reduced.
The rotor comprises a mounting hole 331, a positioning screw and a spindle, wherein the mounting hole 331 is provided with a screw hole 332, and the spindle of the rotor 21 is positioned by screwing the positioning screw into the screw hole 332. Therefore, the transmission shaft can transmit power to the generator rotor more reliably, and the problem that the generator rotor is loosened is avoided.
In this embodiment, it is further preferable that a connection portion 31 is provided at one end of the transmission shaft 30 away from the bearing 40, and the connection portion 31 can be connected to a main shaft of the engine, thereby realizing power transmission. Of course, in this embodiment, a driving wheel mounting portion 32 may be further disposed on the driving shaft 30, a key groove is formed on the driving wheel mounting portion 32, and power transmission is achieved by mounting a driving wheel on the driving wheel mounting portion 32 and mounting a flat key, so as to drive the driving shaft to rotate.
The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
