Technical Field
[0001] The present invention relates to the technical field of airships, and in particular to a tethered airship. Background Art
[0002] The advantage of a tethered airship is that it can stay in the air for a long time, so airship maintenance is extremely important. Altitude and temperature have a great influence on the expansion of gas, so the airship needs to have its own pressure regulating system to ensure the flight safety of the airship and its own safety.
[0003] Conventional optoelectronic composite cables can only support power supply and optical fiber, so the airship sky end needs to have a self-regulating system. To ensure the airship's endurance, the airship needs to be divided into two air bags, air and helium. The helium bag provides lift, and the air bag provides pressure regulation to maintain the shape. The electric adjustment system may have uncertainties due to weather and the equipment's own conditions. If an accident occurs, the airship will need to land for maintenance, which will affect the progress of the experiment. Summary of the invention

[0015] In order to make the technical purpose, technical solution and beneficial effects of the present invention more clear, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.
[0016] A tethered airship provided by the present invention, as shown in the figure, comprises a helium bag 1, an air pipe 63, a sensor 2, an air compressor 8, an air storage device 9, and a controller 10. The helium bag 1, the air pipe 63, the air compressor 8, and the air storage device 9 are connected in sequence. The sensor 2 is arranged on the helium bag 1. The sensor 2 is arranged as a temperature and pressure sensor for monitoring the internal pressure and temperature of the helium bag 1. The controller 10 is electrically connected to the air compressor 8 and is electrically connected to the sensor 2 through a switch 3. The controller 10 can receive information from the sensor 2 through the switch 3 and control the air compressor 1 accordingly. The working state of the compressor 8 is used to realize the precise adjustment of the air pressure of the helium bag 1, so that the compressor 8 supplies the gas storage device 9 into the helium bag 1, or extracts gas from the helium bag 1 and supplies it to the gas storage device 9. The compressor 8 and the gas storage device 9 are arranged on the ground, which greatly reduces the dead weight of the helium bag 1 and facilitates the maintenance and management. When problems occur, they can be repaired in time without landing the airship, which effectively guarantees the continuity of experiments and use. The gas storage device 9 is arranged as a helium cylinder, which provides a stable source of helium for the pressure regulation and shape maintenance of the airship, and ensures the performance and safety of the airship.
[0017] Furthermore, the tethered airship also includes an optical fiber 61, an electric wire 62 and a load-bearing sleeve 64. The electric wire 62, the optical fiber 61 and the air pipe 63 are all arranged in the load-bearing sleeve 64. The outer sides of the optical fiber 61 and the electric wire 62 are provided with a shielding layer 65 located in the load-bearing sleeve 64. The switch 3 is electrically connected to the controller 10 through the optical fiber 61, which ensures the stability and anti-interference of data transmission, and can efficiently transmit the data collected by the sensor 2 to the controller 10 and receive the instructions of the controller 10. The tethered airship also includes an internal power supply 12, which is electrically connected to the sensor 2 to power it. At the same time, the internal power supply 12 is connected to the external power supply 13 on the ground through the electric wire 62, which ensures that the power supply of the entire system is stable and reliable, and avoids equipment failures due to power problems.
[0018] The present invention is also provided with a pod 4, which is connected to the helium bag 1. The internal power supply 12 and the switch 3 are located in the pod 4, which is convenient for centralized management and maintenance of related equipment and optimization of the structural layout of the airship. The internal power supply 12 and the switch 3 are electrically connected so that the internal power supply 12 supplies power to the switch 3.
[0019] At the same time, the device also includes a cable 11 for restraining the helium bag 1. The cable 11 is respectively connected to the helium bag 1 and the bearing sleeve 64 (or the optoelectronic slip ring 5). The bearing sleeve 64 is fixed on the ground or wound on a winch 7 on the ground. The winch 7 is fixed on the ground to ensure that it can work safely and reliably under various environmental conditions.
[0020] A structure having a load-bearing sleeve 64 in which an optical fiber 64, an air pipe 63, an electric wire 62 and a shielding layer 65 are arranged is defined as an optoelectronic composite cable 6. The optoelectronic composite cable 6 is wound on a winch 7 on the ground, which facilitates the operation of retracting and releasing the composite cable 6, further improving the convenience and practicality of the airship system.
[0021] Since the airship is affected by wind in the sky and is easy to rotate in the air, in order to prevent the optoelectronic composite cable 6 from getting tangled, as an optional implementation method, the device also includes an optoelectronic slip ring 5, which is a prior art. The optical path, electrical circuit and gas path of the optoelectronic slip ring 5 are respectively connected to the optical fiber 61, the air pipe 63 and the electric wire 62, the internal power supply on the helium bag 1 is electrically connected to the circuit of the optoelectronic slip ring 5, the switch 3 on the helium bag is electrically connected to the optical path of the optoelectronic slip ring 5, and the gas path of the optoelectronic slip ring 5 is connected to the charging and discharging joint of the helium bag.
