[0057] As shown in Figure 1 , the long-term hovering energy supply system comprises a hovering energy supply station 1, a ground energy support unit 10, and a traction unit.

[0058] The ground energy guarantee unit 10 is connected with the air-occupying energy supply station 1 through the energy conveying belt 12 to provide energy for the air-occupying energy supply station 1. The ground energy guarantee unit 10 is used for providing energy guarantee including electric energy, gas energy (such as hydrogen) and the like, and communication guarantee. Based on this, the communication cable, the power supply cable and the gas supply pipeline and the like are integrated in the energy conveying belt 12.

[0059] The air-occupying energy supply station 1 is a floating object provided with an energy supply unit 16, which can be a hot air balloon, a gas bag, a flying wing parachute with a gas bag and the like. When the hot air balloon is used, the ground energy guarantee unit 10 provides gas fuel for the hot air balloon through the energy conveying belt 12, so that the hot air balloon has long-term air-occupying capability. When the gas bag, the flying wing parachute with a gas bag and the like are used, the ground energy guarantee unit 10 provides helium or hydrogen and the like for the gas bag through the energy conveying belt 12, so that the gas bag has buoyancy. The energy conveying belt 12 can realize timely gas supply for the gas bag (specifically, a gas supply port is arranged on the gas bag of the air-occupying energy supply station 1, a gas filling valve is arranged at the gas supply port, the gas filling valve automatically senses the gas pressure of the gas bag, and when the gas pressure in the gas bag is lower than a set value, the gas filling valve automatically supplies gas to the gas bag, and when the gas pressure in the gas bag reaches the set value, the gas filling valve stops gas supply), thereby realizing long-term residence of the air-occupying energy supply station 1 in the air. The air-occupying energy supply station 1 is provided with a gas filling and discharging valve 15, which is used for manual or automatic gas filling and discharging of the gas bag in the floating object.

[0060] The energy supply unit 16 includes an aircraft energy supply unit and a fixing device. The fixing device is used for fixing an external aircraft, so that the external aircraft can stay at a set position of the air-occupying energy supply station 1, to realize energy supplement (such as power supply, gas supply and the like) of the external aircraft through the aircraft energy supply unit. After the energy supplement of the external aircraft is completed, the aircraft energy supply unit closes the energy channel, and the fixing device releases the external aircraft. In addition, the energy supply unit 16 also has the function of information interaction with the external aircraft.

[0061] The air-anchored energy supply station 1 is provided with an air-anchored energy support unit 2, which is an energy distribution system of the air-anchored energy supply station 1. The energy transmitted to the air-anchored energy supply station 1 through the energy transmission belt interface 8 is distributed to the airbags, loads in the air-anchored energy supply station 1 and provided to the external space vehicles for energy supplement through the air-anchored energy support unit 2. That is, the energy transmission between the air-anchored energy supply station 1 and the ground, the air-anchored energy supply station 1 and the external space vehicles is realized through the air-anchored energy support unit 2, the external space vehicles automatically supplement energy on the air-anchored energy supply station 1, and other same type energy and communication information obtained by the external space vehicles from the sky can be stored in the system or transmitted back to the ground station.

[0062] The traction assembly is connected with the air-anchored energy supply station 1 through the traction cable 5 to realize the traction of the air-anchored energy supply station 1, bear the weight of the air-anchored energy supply station 1 and the loads carried thereon, and bear the tension generated by the air-anchored energy supply station 1 and the loads carried thereon against the wind through the traction cable 5. Through the bearing of the traction cable 5, the energy transmission belt 12 can avoid bearing excessive tension, and the reliability of energy transmission is ensured.

[0063] Embodiment 2:

[0064] On the basis of the above-mentioned embodiment 1, in order to realize the energy supply to the external vehicles at different altitudes, a plurality of air-anchored energy supply stations 1 are arranged on the energy transmission belt 12 along the height direction. Specifically, the air-anchored energy supply station 1 at the upper end of the energy transmission belt 12 is connected as a main supply station, and a plurality of air-anchored energy supply stations 1 are arranged on the energy transmission belt 12 below the main supply station as auxiliary supply stations. Specifically, the auxiliary supply station is connected with the energy transmission belt 12 through the fastening rope B30 to realize the traction of the auxiliary supply station, and is communicated with the energy transmission belt 12 through the energy transmission branch to realize the transmission of energy from the energy transmission belt 12 to the auxiliary supply station and the interaction of information.

[0065] The auxiliary supply station and the main supply station are configured in the same way, that is, the energy supply unit 16 and the air-anchored energy support unit 2 are also arranged on the auxiliary supply station.

[0066] The auxiliary supply station has the following functions: first, it can share the weight of the main supply station and the energy transmission belt 12, and the tension generated by the main supply station and the energy transmission belt 12 against the wind; second, it can provide a stepped pressure boosting transmission gas source to ensure that the energy transmission belt can transmit the gas source higher and farther; and third, it can provide energy support for external vehicles with different altitude requirements.

[0067] Embodiment 3:

[0068] On the basis of the above-mentioned embodiment 1 or embodiment 2, further:

[0069] The energy conveying belt 12 is also provided with an energy conveying belt ground take-up and pay-off device 11 for taking up and paying off the energy conveying belt 12. In this example, the energy conveying belt ground take-up and pay-off device 11 adopts a reciprocating cable grabbing mechanism, which comprises a self-control opening and closing lock and a reciprocating mechanism. The reciprocating mechanism is vertically arranged, and the self-control opening and closing lock is installed on the reciprocating mechanism and can repeatedly move up and down on the reciprocating mechanism. The energy conveying belt 12 passes through the self-control opening and closing lock. The self-control opening and closing lock realizes clamping or releasing of the energy conveying belt 12 by opening and closing. Thus, the self-control opening and closing lock reciprocates on the reciprocating mechanism, repeatedly pulls down the energy conveying belt 12, and realizes orderly recovery of the energy conveying belt 12.

[0070] The traction assembly comprises a traction cable ground take-up and pay-off device 9, a fastening rope A3 and a traction cable 5. The traction cable ground take-up and pay-off device 9 is connected to the hovering energy supply station 1 (i.e. the main supply station) arranged at the top end of the energy conveying belt 12 through the traction cable 5. Specifically, a plurality of fastening ropes A3 are arranged on the hovering energy supply station 1 (i.e. the main supply station) at the top end of the energy conveying belt 12. One end of each fastening rope A3 is connected to the main supply station, and the other end converges into a node and is connected to the traction cable 5. The traction cable ground take-up and pay-off device 9 is used to take up and pay off the traction cable 5.

[0071] The energy conveying belt ground take-up and pay-off device 11 and the traction cable ground take-up and pay-off device 9 are arranged respectively, which can separate the taking up and paying off of the energy conveying belt 12 and the traction cable 5, and form synchronous and complementary taking up and paying off.

[0072] Embodiment 4:

[0073] On the basis of the above-mentioned embodiments 1-3, in order to minimize the force on the energy conveying belt 12 during floating, but at the same time not to affect the independent taking up and paying off of the traction cable 5 and the energy conveying belt 12, a binding mechanism is arranged between the parallel traction cable 5 and the energy conveying belt 12. During floating, the energy conveying belt 12 is transversely bound to the traction cable 5 through the binding mechanism, so as to bear the weight of the energy conveying belt 12 (and the auxiliary supply station connected to the energy conveying belt) through the traction cable 5. During the taking up and paying off of the traction cable 5 and the energy conveying belt 12, the binding mechanism releases the binding of the energy conveying belt 12, so as to realize the independent taking up and paying off of the energy conveying belt 12 and the traction cable 5 (it is worth noting that although the two are independent, they are both connected to the main supply station, so they need to be taken up and paid off at the same time to realize the taking up and paying off of the main supply station; and the taking up and paying off of the two can be made as synchronous as possible through the control of the traction cable ground take-up and pay-off device 9 and the energy conveying belt ground take-up and pay-off device 11).

[0074] The binding structure includes the cable ring 6, the fastening plug 7 and the fastening band 13; a plurality of cable rings 6 capable of freely sliding along the traction cable 5 in the longitudinal direction are arranged on the traction cable 5 at intervals, and the fastening band 13 is arranged on the energy supply belt 12 corresponding to each cable ring 6.

[0075] The fastening band 13 is used to connect the energy supply belt 12 and the cable ring 6; at the same time, when the auxiliary supply station is arranged, the auxiliary supply station is connected with the fastening band 13 through a plurality of fastening ropes B30, so as to realize the connection between the auxiliary supply station and the energy supply belt 12. The auxiliary supply station can be connected with one fastening band 13, or can be connected with a plurality of adjacent fastening bands 13. In addition, the internal cavity of the fastening band 13 is communicated with the energy supply belt 12, and the interface (i.e. the supply station interface 4 of the auxiliary supply station) for supplying energy to the auxiliary supply station is also arranged on the fastening band 13.

[0076] The end of the fastening band 13 towards the cable ring 6 is connected with the cable ring 6, and the fastening band 13 is provided with a fastening plug 7 (such as a spherical fastening plug 7) at the end connected with the cable ring 6. When the energy supply belt 12 is inflated, the fastening plug 7 is pushed to move outward (i.e. towards the cable ring 6) transversely, abuts against the traction cable 5, and promotes the fastening band 13 to be bound on the traction cable 5, so as to be able to bind the energy supply belt 12 on the traction cable 5 in the transverse direction, to provide a support point for the energy supply belt 12, so as to reduce the stress of the energy supply belt 12.

[0077] During the winding and unwinding of the energy supply belt 12 and the traction cable 5, the amount of inflation in the energy supply belt 12 is not enough to bind the energy supply belt 12 on the traction cable 5; at this time, the fastening plug 7 does not abut against the traction cable 5 (abuts but the abutting force is small or the two do not contact), at this time the cable ring 6 can freely slide along the traction cable 5 in the longitudinal direction, so that the distance between the energy supply belt 12 and the traction cable 5 can be limited during the winding and unwinding process, to avoid that the two shake too much in the air due to the influence of wind force, and at the same time, the synchronous and complementary winding and unwinding can be realized on the basis of separating the winding and unwinding processes of the two.

[0078] Embodiment 5:

[0079] On the basis of the above-mentioned embodiments 1-4, this embodiment gives a specific implementation mode of taking the hot air balloon as the main supply station, i.e. this embodiment provides a hovering energy supply system using the buoyancy generated by the combustion of hot air and low-density gas.

[0080] As shown in Figure 2 The hot air balloon includes a hot air balloon gas bag 17 and a load cabin 23, the hot air balloon gas bag 17 is connected with the load cabin 23 through a plurality of connecting ropes 18, to ensure that the hot air balloon gas bag 17 drives the load cabin 23 to rise through the connecting ropes 18 when the hot air balloon gas bag 17 rises.

[0081] The traction cable 5 is directly connected to the payload compartment 23 via a traction cable tethering bolt, and the traction cable 5 is fixed to the payload compartment 23 of the tethered hot air balloon via the traction cable tethering bolt.

[0082] The payload compartment 23 houses a gas pump 24, a pressurized gas storage tank 19, and a burner 26. The gas pump 24 is connected to the gas supply pipeline in the energy conveyor belt 12 via a gas pipe 20, transporting gaseous fuel through the gas pipe 20. The gas pump 24 is also connected to the pressurized gas storage tank 19, drawing gas from the gas supply pipeline of the energy conveyor belt 12 into the pressurized gas storage tank 19. The pressurized gas storage tank 19 stores the gas and is connected to the burner 26 via a flow regulating valve 22. The burner 26 heats the air by burning gas (such as hydrogen). The hot air balloon gasbag 17 confines the heated air, creating air with a lower density than the air outside the hot air balloon gasbag, generating lift and propelling the buoyancy system upwards.

[0083] The payload in the payload compartment 23 is connected to the power supply cable in the energy delivery belt 12 via cable 21. Cable 21 is used to transmit electrical energy to provide power for space equipment or to replenish power for external spacecraft.

[0084] In addition, the pressurized gas storage tank 19 is also equipped with a gas replenishment interface for replenishing gas energy to external aircraft.

[0085] Furthermore, a cooling and heat collector 25 is also provided in the payload compartment 23; the cooling and heat collector 25 is used to cool the burner 26 and prevent the burner 26 from overheating; at the same time, the cooling and heat collector 25 collects the heat energy of the burner 26 body and conducts the collected heat energy through pipes to the payload equipment and other space antifreeze equipment that need to be protected in the payload compartment 23.
