Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
As shown in fig. 4, if the purpose that the rotor mechanism does not shield the geosynchronous broadband satellite signal transmission mechanism 5 is to be realized, the geosynchronous broadband satellite signal transmission mechanism 5 can be installed at the tail part 12 of the unmanned aerial vehicle, but after the test, the geosynchronous broadband satellite signal transmission mechanism 5 is arranged at the position, so that the gravity center of the unmanned aerial vehicle is unstable, and the unsafety of the structural stress of the tail part 12 of the unmanned aerial vehicle occurs, and meanwhile, the crosswind of the tail part 12 causes serious interference to the unmanned aerial vehicle.
As shown in fig. 5, of course, the geosynchronous broadband satellite signal transmission mechanism 5 may also be installed at the top of the rotor mechanism 4, but after the test, although the problem of blocking of the rotor mechanism 4 on the geosynchronous broadband satellite signal transmission mechanism 5 is solved, the severe shaking of the geosynchronous broadband satellite signal transmission mechanism 5 occurs due to long-term vibration in the flight process of the unmanned aerial vehicle, and the transmission of signals is still affected.
In order to solve the above problem, as shown in fig. 6, an embodiment of the present invention provides a tandem dual rotor unmanned aerial vehicle, which includes a main beam 3; rotor mechanism 4 and geosynchronous broadband satellite signal transmission mechanism 5 all locate on girder 3, it predetermines the distance to have between edge portion 43 of rotor mechanism 4 and the geosynchronous broadband satellite signal transmission mechanism 5.
Set up rotor mechanism 4 on girder 3, set up power supply and drive mechanism in the inside of fuselage 1 to this drive mechanism is connected with rotor mechanism 4, drives rotor mechanism 4 and rotates, thereby controls the rising and the descending of fuselage 1. Meanwhile, a preset distance is reserved between the geosynchronous broadband satellite signal transmission mechanism 5 and the edge part 43 of the rotor wing mechanism 4, so that the rotor wing mechanism 4 is prevented from shielding the geosynchronous broadband satellite signal transmission mechanism 5 in the rotating process, the signal transmission of the geosynchronous broadband satellite signal transmission mechanism 5 is improved, and the unmanned aerial vehicle can run more stably; meanwhile, signal loss is reduced, and the flight distance of the tandem double-rotor unmanned aerial vehicle is increased due to the fact that signal attenuation of a geosynchronous broadband satellite signal transmission mechanism 5 is prevented from weakening, and the tandem double-rotor unmanned aerial vehicle is not limited by terrain shielding; the system has the advantages that the system can keep ultra-low altitude communication and image transmission during patrol, investigation, express transportation, emergency rescue and military operation, particularly on the sea and long-distance flight, meanwhile, remote lifting and descending and the like are ensured, and the high-level application requirements on the tandem double-rotor unmanned aerial vehicle are met in a larger space.
In this embodiment, it is greater than 0 to predetermine the distance for leave certain clearance between rotor mechanism 4 and the geosynchronous broadband satellite signal transmission mechanism 5, prevented that rotor mechanism 4 from influencing the signal transmission of geosynchronous broadband satellite signal transmission mechanism 5 at rotatory in-process, also prevented that rotor mechanism 4 cuts to pieces at rotatory in-process and rubs to geosynchronous broadband satellite signal transmission mechanism 5, improved the life of geosynchronous broadband satellite signal transmission mechanism 5.
Further, the geosynchronous broadband satellite signal transmission mechanism 5 can be arranged in the middle of the main beam 3, and certainly can be arranged at other parts of the main beam 3, as long as the rotor wing mechanism 4 does not shield the geosynchronous broadband satellite signal transmission mechanism 5 in the rotating process. The specific setting position can be set according to different models.
As shown in fig. 6, the rotor mechanisms 4 are two and respectively disposed at the end of the main beam 3, the geosynchronous broadband satellite signal transmission mechanism 5 is disposed at the middle of the main beam 3, and the distances between the two rotor mechanisms 4 and the geosynchronous broadband satellite signal transmission mechanism 5 are both greater than 0, so that the rotor mechanisms 4 are prevented from shielding the geosynchronous broadband satellite signal transmission mechanism 5 in the rotating process.
To ensure the safety of all aircraft, the air traffic control authority dictates that the altitude of the drone is limited by the global air traffic control authority and cannot be higher than 500 feet, i.e. 150 meters. Above 150 meters, airspace flight must be applied. Over 150 meters may collide with other aircraft. Therefore, low-altitude flight is necessary, but in low-altitude flight, the radio can meet the curvature of the earth and the shelters of mountains and buildings, so that the unmanned aerial vehicle cannot use flight control communication, which leads to the abnormal operation of the unmanned aerial vehicle. If long-distance flight is required, the communication problem of the unmanned aerial vehicle needs to be solved. In this embodiment, the geosynchronous broadband satellite signal transmission mechanism 5 is a geosynchronous broadband satellite antenna, and meanwhile, the diameter of the geosynchronous broadband satellite antenna is 1-1.2m, and the arrangement of the geosynchronous broadband satellite antenna with the diameter enables the tandem dual-rotor unmanned aerial vehicle to be widely applied to high-latitude areas and to be suitable for strong operational environment and survival capability in the fields of emergency rescue and military. At present, the communication problem of low-altitude flight can be completely solved only by adopting satellite communication, namely, the unmanned aerial vehicle directly establishes communication with a satellite and receives and transmits an operation instruction and a high-definition video image.
Through the setting of geosynchronous broadband satellite antenna for at the in-process that carries out signal transmission, can not receive the restriction of distance and obstacle, thereby can realize this unmanned aerial vehicle's ultralow altitude and long distance flight, also can carry out the receipt and the transmission of flight control signal and video signal through the satellite simultaneously, thereby realize allopatric take off and land, increased this tandem two rotor unmanned aerial vehicle's practicality, mobility and disguised nature. Wherein, the geosynchronous broadband satellite signal transmission mechanism 5 includes: a bracket 51, a signal transmitter arranged inside the bracket, and a cover 52 arranged outside the signal transmitter. The bracket 51 is mounted on the main beam 3 by screws, so that the close connection between the geosynchronous broadband satellite signal transmission mechanism 5 and the main beam 3 is realized, and the mounting and dismounting of the geosynchronous broadband satellite signal transmission mechanism 5 are facilitated.
In this embodiment, the rotor mechanism 4 includes a main shaft 41, which is disposed on the main beam 3 and is rotatably connected to the main beam 3; the rotor blade 42 is arranged at one end of the main shaft 41 far away from the main beam 3, and the main shaft 41 is connected with a power source transmission mechanism so as to rotate and drive the rotor blade 42 to rotate; the end of the rotor blade 42 away from the axis of the main shaft 41 is an edge 43, that is, the position of the outer edge tip of the rotor blade 42.
The height of the main shaft 41 can be greater than the height of the geosynchronous broadband satellite signal transmission mechanism 5, so that the rotor blades 42 arranged on the main shaft 41 cannot necessarily shield the geosynchronous broadband satellite signal transmission mechanism 5 in the rotating process; of course, the height of the main shaft 41 may also be less than or equal to the height of the geosynchronous broadband satellite signal transmission mechanism 5, and at this time, a distance of 5-10cm may be left between the edge portion 43 and the geosynchronous broadband satellite signal transmission mechanism 5, and the gap is set so that the rotor blade 42 does not shield the geosynchronous broadband satellite signal transmission mechanism 5 during the rotation process, thereby ensuring the transmission of signals.
As shown in fig. 7, a telescopic mechanism 6 may be further disposed between the geosynchronous broadband satellite signal transmission mechanism 5 and the main beam 3, and the arrangement of the telescopic mechanism 6 may adjust a relative relationship between the geosynchronous broadband satellite signal transmission mechanism 5 and the rotor mechanism 4, so as to further prevent the rotor mechanism 4 from shielding the geosynchronous broadband satellite signal transmission mechanism 5. In this embodiment, the telescopic mechanism 6 may be a cylindrical structure, and a plurality of through holes are opened along the axial direction of the cylindrical structure, and the through holes are inserted through the through holes of different heights on the bracket 51 by screws, so as to be connected with the cylindrical structure, thereby adjusting the height of the geosynchronous broadband satellite signal transmission mechanism 5.
Further, since a geosynchronous broadband satellite signal transmission mechanism 5 needs to be provided between the two rotor mechanisms 4, there are two means: the first method can reduce the diameter of the rotor wing 42 in the rotor wing mechanism 4 without changing the length of the main beam 3, thereby leaving installation space for installing the geosynchronous broadband satellite signal transmission mechanism 5; the second type can increase the length of the main beam 3, the increased length of the main beam 3 is to allow the lower geosynchronous broadband satellite signal transmission mechanism 5 to be installed, and the edge part 43 of the rotor mechanism 4 is at least 5-10cm away from the geosynchronous broadband satellite signal transmission mechanism 5, so that the rotor mechanism 4 is ensured not to block the signal transmission of the geosynchronous broadband satellite signal transmission mechanism 5.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
