Description

Technical Field

[0001] The utility model relates to the technical field of direction-finding monitoring machines, in particular to a balloon-mounted aerial radio monitoring and direction-finding device. Background Art

[0002] A direction-finding antenna relies on the amplitude difference of electromagnetic waves from different receiving elements to determine the direction of incoming waves in free space. Prior art direction-finding methods primarily include amplitude-ratio direction-finding, phase-ratio direction-finding, and time-difference direction-finding. Amplitude-ratio direction-finding utilizes the antenna's directional characteristics to determine direction based on the maximum or minimum value of the antenna's induced potential. This method rotates the antenna, and when the antenna output reaches an extreme value, the direction of the incoming wave is determined by the antenna's pointing direction. Phase-ratio direction-finding, on the other hand, involves measuring the phase difference between the received potentials of two or more antenna elements arranged in a specific configuration when an electromagnetic wave reaches two antennas with identical characteristics. Finally, time-difference direction-finding uses a method where the time difference between the electromagnetic wave reaching the receiving antenna is proportional to the path difference. Three direction-finding stations are used to measure the time difference between the signal's arrival at each station.

[0003] Currently, existing flying direction-finding monitoring equipment is carried by drones. For example, the Chinese utility model patent application, "Apparatus for Mounting a U / V-Band Direction-Finding Antenna on a Micro-Rotor UAV," with publication number CN215155590U, employs a U / V-band direction-finding antenna mounted on the underside of the micro-rotor UAV. During operation, the micro-rotor UAV bears all the weight, resulting in a short flight time.

[0004] Therefore, there is an urgent need to propose a balloon-borne aerial radio monitoring and direction-finding device with a simple structure and reliable flight. Utility Model Content

[0005] In view of the above problems, the purpose of this utility model is to provide a balloon-mounted aerial radio monitoring and direction-finding device. The technical solution adopted by this utility model is as follows:

[0006] A balloon-mounted aerial radio monitoring and direction-finding device comprises a balloon fixing net, a balloon arranged in the balloon fixing net, a direction-finding antenna suspended below the balloon fixing net, an aircraft arranged on the direction-finding antenna, a monitoring and direction-finding receiver arranged on the aircraft and electrically connected to the direction-finding antenna, an electromagnetic three-way valve fixed on the aircraft and connected to the balloon via a pipeline, an inflation tube having one end connected to the electromagnetic three-way valve, and a gas cylinder connected to the other end of the inflation tube; the gas cylinder contains a gas having a density less than that of air; and the gas cylinder inflates the balloon via the inflation tube and the electromagnetic three-way valve.

[0007] Furthermore, a lower support base is provided at the bottom of the direction-finding antenna.

[0008] Furthermore, a plurality of upper support seats are provided between the aircraft and the direction-finding antenna; the upper support seats are arranged in a circular array.

[0009] Furthermore, the direction-finding antenna is provided with a plurality of lifting ears, and the lifting ears are connected to the balloon fixing net.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] (1) The present invention employs a balloon fixing net, a balloon, and an electromagnetic three-way valve to fill the balloon with a gas less dense than air, thereby supporting the monitoring direction-finding receiver, direction-finding antenna, etc., thereby reducing the load on the aircraft and extending its flight time. Furthermore, the balloon of the present invention bears the overall buoyancy, and the aircraft adjusts its position.

[0012] (2) The utility model is provided with an electromagnetic three-way valve, which connects the balloon, the inflation tube and the gas cylinder during inflation. When descending, the electromagnetic three-way valve is used to discharge the gas in the balloon, and the balloon slowly descends under the action of gravity.

[0013] (3) The utility model ensures support reliability by providing a lower support seat and an upper support seat.

[0014] (4) The utility model provides a balloon fixing net to facilitate the storage of balloons.

[0015] In summary, the utility model has the advantages of simple structure and reliable flight, and has high practical value and promotion value in the field of direction-finding monitoring aircraft technology. BRIEF DESCRIPTION OF THE DRAWINGS
