Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example 1
As shown in fig. 1, the searching apparatus of the wreck unmanned aerial vehicle provided in this embodiment 1 includes:
the beacon 1 is fixedly connected with the unmanned aerial vehicle through a rope 2, and can separate from the unmanned aerial vehicle and float on the water surface when the unmanned aerial vehicle falls into the water;
the satellite positioning system receiver is hermetically arranged in the beacon 1 and used for receiving signals of the satellite positioning system;
and the radio station is hermetically arranged in the beacon 1 and used for sending a radio station signal to the ground end receiving equipment.
In the embodiment, the satellite positioning system adopts a GNSS positioning system, the satellite positioning system receiver adopts a receiver corresponding to the GNSS positioning system, and the GNSS positioning system (global navigation satellite system) is an air-based radio navigation positioning system which can provide all-weather 3-dimensional coordinates and speed and time information for a user at any place on the earth surface or in the near-earth space. Consequently, can accurately obtain the positional information of the unmanned aerial vehicle of the accident through this GNSS positioning system's signal, sending this positional information to ground end receiving equipment through a radio station, the concrete position of the unmanned aerial vehicle of the accident can be learnt fast to the ground end, can arrange the search and rescue ship fast like this and go to the position of unmanned aerial vehicle of the accident, utilize the ship anchor 3 to salvage the unmanned aerial vehicle of the accident ashore, as shown in fig. 2, in order to avoid losing of the information that unmanned aerial vehicle detected.
In practical application, if the buoyancy generated by water to the beacon 1 is set to be larger than the difference value between the gravity of the unmanned aerial vehicle and the buoyancy of the unmanned aerial vehicle in water. Beacon 1 can pull unmanned aerial vehicle by its buoyancy effect after the unmanned aerial vehicle accident falls into water, and beacon 1 can float in the surface of water like this, avoids the interference that the surface of water produced the signal below, and the recognition beacon position that can be more accurate. Of course, under the condition that the precision requirement is moderate, the size of the beacon 1 is also considered, the buoyancy generated by water to the beacon 1 can be set to be slightly smaller than the difference value between the gravity of the unmanned aerial vehicle and the buoyancy of the unmanned aerial vehicle in water, so that the beacon can float in water, and the position of the beacon can also be detected, as shown in fig. 2.
In specific implementation, as an optional implementation mode, the searching device may further include a mounting plate 4, as shown in fig. 3 and 4, the mounting plate 4 may be connected to the top of the unmanned aerial vehicle rotor head 9; the beacon 1 may be mounted on a mounting plate 4. Specifically, the mounting plate 4 may be connected to the top of the drone rotor head 9 by a screw 5. Beacon 1 can be more convenient float like this and break away from unmanned aerial vehicle, avoids the rope to be sheltered from by the screw.
On the basis of the above-described embodiment of the mounting plate 4, the searching apparatus further comprises a beacon chamber 7, as shown in fig. 5 and 7, the beacon chamber 7 can be fixedly connected to the mounting plate 4 by bolts 6, and then in this embodiment, the beacon 1 can be mounted in the beacon chamber 7. Therefore, the unmanned aerial vehicle is provided with a beacon 1 placing space, namely a beacon cabin 7, so that the installation and protection of the beacon 1, the rope 2 and other structures can be facilitated.
On the basis of the above-described embodiment of the beacon chamber 7, the searching device further comprises a roller 8 for winding the rope 2, as shown in fig. 6, and the roller 8 is installed in the beacon chamber 7 and is located at the bottom of the beacon 1. The setting of gyro wheel 8 can improve the speed and the smooth and easy nature that beacon 1 floats and breaks away from unmanned aerial vehicle.
Example 2
Unlike the various embodiments of example 1 described above, as shown in fig. 8, the roller 8 for winding the rope is fixedly attached directly to the mounting plate 4; of course, the wheels may be mounted directly on the drone, for example, the wheels 8 are fixed to the top of the drone rotor head 9. The mounting plate 4 and the beacon chamber 7 are not essential components and can be increased, decreased, and deformed as appropriate according to the actual situation.
In addition, the beacon cabin 7 can also be directly and fixedly connected to the top of the rotor head 9 of the unmanned aerial vehicle; the beacon 1 is mounted in a beacon chamber 7.
It should be noted that in the above embodiments, in order to make it easier to float and reduce the installation volume, the beacon 1 may be formed in a hemispherical shape, and the round bottom surface of the beacon 1 is provided with a recess for accommodating the roller 8. Thus, the installation space can be saved, and the floating speed can be improved due to the action of the recess.
In the above-mentioned embodiment, all place beacon 1 in unmanned aerial vehicle rotor head 9 tops, but not only be limited to in practical application and place in unmanned aerial vehicle rotor head 9 tops, can also install beacon 1 on positions such as unmanned aerial vehicle fuselage, fin. The specific setting position of the beacon 1 is not limited as long as the normal operation of the drone is not hindered.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed.
