A ground mat 7 is laid on the ground below the sac 1, and the inflating device 5 is connected to a gas cylinder rack 6 for placing gas cylinders.

As shown in FIG. 2 , the skeleton 8 includes an oblique rod 801, a vertical rod 802, a cross rod 803, a main rod 804 and a connecting rod 805; the cross rod 803 is provided with two, which are obliquely inserted into the rod holes reserved on the narrow side of the abdomen of the bladder body 1, and the main rod 804 is inserted into the rod hole reserved on the wide side of the abdomen of the bladder body 1. The two cross rods 803 are locked on the main rod 804 by a U-shaped metal piece. The tail wing of the bladder body 1 is a right triangle, and the long side of the right angle is connected to the rod hole of the main rod 804. The vertical rod 802 passes through the rod hole reserved on the short side of the right angle, and the top is locked on the main rod 804 by a U-shaped metal piece. The U-shaped metal piece simultaneously connects the two cross rods 803, the main rod 804 and the vertical rod 802. The oblique rod 801 It is obliquely passed through the tail wing of the capsule 1, one end of the oblique rod 801 is connected to the vertical rod 802 through a U-shaped metal piece, the other end of the oblique rod 801 is connected to the vertical rod 804 through a U-shaped metal piece, the connecting rod 805 is respectively fixed to the vertical rod 802 and the oblique rod 801 through U-shaped metal pieces, an H-shaped metal structure is installed at the junction of the connecting rod 805 and the oblique rod 801, the upper half of the H-shaped metal structure is fixed to the junction of the connecting rod 805 and the oblique rod 801 through screws, the lower half of the H-shaped metal structure is mounted with a direction-finding antenna array through screws, the onboard power supply 4 is mounted on the oblique rod 801, and the position combined with the connecting rod 805 is mounted on the H-shaped metal structure.

As shown in Figure 3, the wire retractor 2 includes a base plate 205 and a drum 201, a roller 202, a wire retracting port 204 and a setting box 203 located on the base plate 205; the drum 201 is connected to the roller 202 and the wire retracting port 204 respectively, the wire retracting port 204 is connected to the setting box 203, one end of the mooring cable is connected to the drum 201 through the wire retracting port 204, and the wire retracting port 204 includes a first pulley 2041 and a second pulley 2042; the second pulley 2042 is located directly above the first pulley 2041, the installation direction of the second pulley 2042 is perpendicular to the installation direction of the first pulley 2041, the gap between the first pulley 2041 and the second pulley 2042 is the diameter of the mooring cable, and the diameter of the second pulley 2042 is not fixed.

As shown in FIG4 , the third pulley 2043 is two pulleys with the same installation direction, and the gap between the two pulleys is the diameter of the mooring cable. The first pulley 2041 is also two pulleys with the same installation direction, and the gap between the first pulley 2041 and the third pulley 2043 is the diameter of the mooring cable. The first pulley 2041 and the third pulley 2043 are perpendicular to each other. The function of the retractable cable port 204 is to constrain the posture of the mooring cable entering the retractable cable device and to convert the traveling direction of the mooring cable. When the mooring cable is in the air, the posture is mainly vertical to the ground, and under the action of wind force, it swings with the wind. When the mooring cable is retracted, the mooring cable passes through the gap in the middle of the first pulley 2041 from top to bottom, and the mooring cable that passes through the first pulley 2041 can only swing in a direction parallel to the first pulley 2041 after being constrained by the first pulley 2041. When the mooring cable passes through the gap in the middle of the third pulley 2043 and passes through the mooring cable of the third pulley 2043, it cannot swing in any direction after being constrained by the third pulley 2043, thereby completing the constraint of the mooring cable. At the same time, after the mooring cable passes through the third pulley 2043, the traveling direction is also converted from the vertical direction to the horizontal direction, and it reaches the roller 202, and then reaches the drum 201 after passing through the roller 202. In actual use, the mooring cable is affected by the wind in the air, and the swing range is very large. This swing is also transmitted to the mooring cable of the retractable line port 204, and the mooring cable in the first pulley 2041 of the retractable line port 204 also swings accordingly. When the swing of the mooring cable is perpendicular to the installation direction of the first pulley 2041, the swing of the mooring cable will be constrained by the first pulley 2041. When the swing of the mooring cable is parallel to the installation direction of the first pulley 2041, the swing of the mooring cable cannot be constrained, causing the mooring cable to slip out of the first pulley 2041, and the first pulley 2041 will be entangled or squeezed by the mooring cable, resulting in damage to the mooring cable.

In this embodiment, as shown in FIG5 , a group of pulleys, namely the second pulley 2042, is added directly above the first pulley 2041. The installation direction of the second pulley 2042 is perpendicular to the installation direction of the first pulley 2041. The gap between the pulleys is the diameter of the mooring cable. The diameter of the second pulley 2042 is variable. The closer to the fixed position of the pulley, the larger the diameter of the pulley, and the smaller the gap between the pulleys, until there is no gap between the two pulleys. When the mooring cable enters the retractable line port 204, it first enters the second pulley 2042. At this time, the swing of the mooring cable is also random. When the swing direction of the mooring cable is perpendicular to the installation direction of the second pulley 2042, the swing of the mooring cable will be constrained by the second pulley 2042. When the swing direction of the mooring cable is parallel to the installation direction of the second pulley 2042, there is no gap at both ends of the second pulley 2042, and the mooring cable will not slip out of the second pulley 2042, and the second pulley 2042 will not be wound around or squeezed by the mooring cable, resulting in the phenomenon of damage to the mooring cable.

In this embodiment, the mooring cable first enters the cable retracting port 204. After passing through the cable retracting port 204, the cable retracting port 204 has two functions: one is to prevent the cable from getting stuck when entering the cable retracting port; the other is to keep a certain tension on the cable to prevent the cable from getting entangled. The cable enters the roller 202 (the roller 202 is used to sort the cables when they enter the drum, and this process is called cable arrangement). Through the rotation of the drum 201 and the sliding cooperation of the roller 202, the orderly cable retracting and discharge on the drum 201 is achieved.

In this embodiment, the tether cable is used to supply power from the ground power supply 3 to the airborne power supply 4, and to exchange information between the ground and space through optical fiber, and one end of the tether cable is wound on the reel 2, and the other end of the tether cable is connected to the junction of the connecting rod 805 and the inclined rod 801, and is connected to the DC input terminal and optical port of the airborne power supply 4.

In this embodiment, the floating wing platform composed of the capsule 1 and the skeleton 8 constitutes a launch platform for carrying mission payloads; the ground power supply 3 is converted from an external power supply to supply power to the airborne power supply 4, and the airborne power supply supplies power to the 4 mission payloads; the mooring cable is fixed (anchored) by the retractor 2 to moor the aerial platform, and at the same time, it is an air-to-ground electrical connection and a data connection. The ground power supply 3 supplies power to the aerial part, and the ground power supply 3 exchanges information with the airborne power supply 4, and the aerial part carries a payload to execute the mission; the ground power supply 3 supplies power to the airborne power supply 4 through the mooring cable, and the airborne power supply 4 supplies power to the payload and an optical cable is set for signal transmission; the mooring cable is fixed by the retractor 2 to moor the aerial platform, and at the same time, it is an air-to-ground electrical connection and a data connection; the retractor 2 retracts and releases the mooring cable and anchors, the inflation device 5 decompresses the high-pressure gas, inflates the capsule 1, and lays a ground mat 7 to protect the expansion of the capsule 1.

In this embodiment, the sac 1 is a small airship that can stay in the air at a fixed point; the tethered power supply (including the ground power supply 3 and the airborne power supply 4) provides power supply to the system equipment through the ground power supply; the tethered cable is used to connect the ground equipment with the aerial equipment, and realize telecommunication and signal transmission at the same time; the cable retractor 2 is used to manage and store cables; the gas recycling device (including the gas filling device 5 and the gas cylinder rack 6) is used to realize the inflation and gas recovery of the sac 1.

In this embodiment, the power supply is transported by aluminum box packaging. After opening, the airborne power supply 4 is mounted on the floating wing platform, and the ground power supply 3 is assembled in the outer cover of the retractable cable 2. The cable transportation packaging adopts a bobbin wound and stored in a carton, which is assembled on the bobbin of the retractable cable 2 after opening. The structure of the retractable cable 2 is shown in Figure 3.

In this embodiment, the bladder 1 and the frame 8 serve as the main components of the floating wing platform. The bladder 1 can be filled with helium to maintain its shape and generate buoyancy, so that the floating wing platform can be lifted; the frame 8 increases the rigidity of the tail wing and the vertical wing surface, so that the floating wing platform is formed, and is conducive to the connection of the mooring cable and the mounting of the load; after the frame 8 is installed, the tail wing can provide auxiliary lift for the shape-maintaining bladder 1 with the help of wind power, and the vertical wing surface allows the floating wing to maintain a windward heading.

In this embodiment, the system power supply consists of a ground part (ground power supply 3) and an air part (airborne power supply 4). The ground power supply 3 converts the mains electricity (or generator power) into high-voltage DC and transmits it to the airborne power supply 4. The airborne power supply 4 outputs low-voltage DC to power the mission payload. The ground power supply 3 and the airborne power supply 4 also provide control signal interfaces.

In this embodiment, the mooring cable is composed of an optoelectronic composite cable and a polymer fiber sheath, and has two functions: on the one hand, the mooring cable is used to supply power from the ground power supply 3 to the airborne power supply 4, and is used for the transmission of low-altitude control signals or data signals; on the other hand, the sheath is woven from a lightweight and high-strength material. Since one end of the mooring cable is fixed to the floating wing platform and the other end is anchored to the ground (stored in the wire drum of the retractor 2), the mooring cable is used to keep the floating wing platform in the air, and the sheath bears most of the tension. The retractor 2 can store and anchor the mooring cable through the wire drum, and is used for the electric retracting and releasing of the mooring cable. The mooring cable is released when opening, stopped when in the air, and retracted when withdrawn.

In this embodiment, the ground power supply 3 is fixed to the bracket plate inside the retractable cable 2 by bolts, the retractable cable 2 can be fixed and anchored to the ground by ground nails, and the inflation device 5 can be placed independently on the flat ground. During inflation, one end is connected to the gas cylinder through a pressure reducing valve, and the other end is connected to the inflation nozzle of the bladder 1 through an air nozzle. The inflation device 5 is used to fill the bladder 1 with helium in the gas cylinder rack 6. Its pressurizing valve can reduce the pressure of the helium in the high-pressure helium cylinder, and inflate the bladder 1 through the air pipe, the chassis, and the pipe with the air nozzle. Among them, the complete set of chassis is equipped with a flow meter to record the amount of inflation. The ground mat 7 is mainly used for the laying protection of the bladder 1 before inflation and the folding protection function of the bladder 1 during withdrawal, to prevent the bladder 1 from being damaged by impurities by direct contact with the ground.

In this embodiment, the tethered balloon floats in the air by the lift generated by helium and is stabilized by the wind direction. The tethered balloon can be pumpkin-shaped, floating wing-shaped, etc. During the entire tethering process, no external electrical equipment is required to provide it with lift or stabilization. Therefore, the entire tethered floating wing system itself does not generate electromagnetic interference signals, and will not affect radio monitoring and direction finding. Floating in the air by the lift generated by helium is a passive power. If there is no helium and no leakage, it can be stranded in the air for a long time. However, the balloon capsule 1 is a high molecular polymer. When filled with helium, the molecular spacing will also increase, resulting in helium leakage. Generally, it can be recycled once a week for air replenishment and continued to be used. In the present invention, after the capsule 1 made of lightweight film material is filled with helium, since helium is lighter than air, the capsule 1 generates lift. The tail wing of the capsule 1 has a certain rigidity after being installed in the skeleton 8. When there is wind, the tail wing generates auxiliary lift for the capsule 1, and the vertical wing surface enables the floating wing platform to have an automatic windward function, thereby ensuring that the wind force is more than the effective surface of the tail wing.

In this embodiment, the ground power supply 3 is connected to 220V AC power for power supply, and the 220V AC voltage is converted into 380V DC voltage, which is connected to the positive and negative electrodes of the front end of the photoelectric slip ring in the retractor 2. The optical port (FC port) of the ground power supply 3 is connected to the optical port (FC port) of the front end of the photoelectric slip ring, and the other end of the photoelectric slip ring is connected to the photoelectric composite cable (tether cable) (light to light, electricity to electricity), and fixed on the crossbar in the middle of the retractor 2. The retractor 2 connects the other end of the wound photoelectric composite cable (tether cable) to the DC input end and optical port of the airborne power supply 4, so that the ground power supply and information exchange are realized through the ground power supply. The network port of the ground power supply 3 can monitor the working status of the airborne load and set the corresponding parameters of the airborne load through the ground terminal, and the DC output port of the airborne power supply 4 supplies power to the load, and the network port is interconnected with the network port of the load. That is, the ground end of the mooring cable is wound on the wire drum of the retractor 2 and fixed by tying a knot in the mooring cable, the photoelectric core wire part is connected to the corresponding photoelectric core wire of the photoelectric slip ring, the aerial end of the mooring cable is connected to the joint of the skeleton 8 of the floating wing platform through a rope buckle, and the photoelectric core wire is connected to the corresponding interface of the airborne power supply 4 through a connector.

In this embodiment, the photoelectric slip ring is arranged on the central axis of the drum 201 inside the retractable and retractable device 2. When the mooring cable on the drum 201 also rotates (during the process of retracting and releasing the cable), the power line at the input end of the retractable and retractable device 2 is stationary. In this way, the wires will be entangled, and eventually the power line will be broken. A set of sliding mechanisms inside the photoelectric slip ring is fixed on one side and rotatable on the other side, which is similar to the working principle of a brushed motor. The rotating side is installed on the central axis of the drum 201, and the output is connected to the mooring cable power line, and the fixed end is connected to the output of the ground power supply 3.

In this embodiment, the moored floating wing platform system is composed of an aerial part and a ground part. The aerial part includes: a floating wing platform (bladder 1 and frame 8), an airborne power supply 4, and the ground part includes components such as a retractable line 2, a ground power supply 3, an inflatable device 5 and a ground mat 7. The mooring cable connects the aerial part and the ground part. Among them, the airborne power supply 4 is mounted on the frame 8 of the floating wing platform, the ground power supply 3 is arranged inside the outer cover of the retractable line 2, and the inflatable device 5 and the ground mat 7 only work when the system is opened. Among them, the aerial part also includes a direction-finding antenna array, and the ground equipment 3 issues a task instruction to the direction-finding antenna array. After receiving the instruction, the antenna arrays of each frequency band select the frequency band through a switching switch. After the selection is completed, the frequency band data is amplified, frequency-converted and filtered by a multi-channel radio frequency receiver to output an intermediate frequency signal. The processed intermediate frequency signal is amplified by an intermediate frequency multi-channel amplifier module. At the same time, the data collected by the positioning antenna is analyzed by the positioning module and transmitted to the logic control unit with the electronic compass data. Finally, the intermediate frequency data and the position data are transmitted to the ground equipment through a multi-channel optical terminal. The direction-finding antenna array can work in a wider detection frequency band range and solve the problem of installing a high-frequency antenna array and applying interferometer direction-finding technology related to short-wave frequency band in a small space. The tethered floating wing platform system in the present invention is used to realize the launch of system equipment, which is equipped with a direction-finding antenna array to obtain electromagnetic signal information in the area.

In this embodiment, the ground part supplies power to the aerial part, and the optoelectronic conversion modules of the ground power supply 3 and the airborne power supply 4 realize information exchange between the ground and the air through optical fiber remote transmission: the aerial part performs mission functions through the carried payload. The ground power supply 3 supplies power to the airborne power supply 4 through a tether (optoelectronic composite cable); the airborne power supply 4 supplies power to the payload; and the tether is used to transmit data or control signals between the air and the ground. When the whole machine is opened, lay the ground mat 7, unfold the floating wing capsule 1 and tie it for protection, pre-inflate and then assemble the skeleton 8, inflate to maintain the shape, assemble the tether, assemble the power supply, assemble the payload and power on for self-inspection; then release it for launch; reverse the operation when withdrawing.
