Description

Technical Field

[0001] This application relates to the field of airship technology, and in particular to a tethered monitoring system. Background Technology

[0002] A tethered aerostat is a non-powered aircraft that uses buoyancy gas to provide static buoyancy and is connected to ground anchorage facilities via tethering cables. It can hover in the airspace at altitudes of hundreds to three thousand meters under conditions of high load, low noise, and long-term loitering, providing a stable platform for communication relay, radar detection, optoelectronic reconnaissance, meteorological observation, disaster assessment, and low-altitude defense.

[0003] Existing long-term tethered aerostats generally adopt a three-point ground mooring scheme of "nose cone + two auxiliary cables". When a sudden gust of wind causes the aerostat to shift laterally or sway, the instantaneous tension distribution of the two auxiliary cables becomes unbalanced. This often results in a sudden increase in the tension of a single cable, which exceeds the strength limit of the local anchor point of the bladder. This causes tearing ruptures in the bladder around the anchor point, leading to leakage of buoyancy gas. Summary of the Invention

[0004] The purpose of this application is to provide a mooring and monitoring system that replaces the three-point mooring system of head cone plus auxiliary cables on both sides with collinear mooring at the head and tail points, so that the sudden gust load is symmetrically distributed along the axis of the airship, eliminating the risk of bladder tearing caused by instantaneous overload of the cable on one side.

[0005] To achieve the above objectives, this application provides a tethered monitoring system, comprising:

[0006] The mooring device is equipped with a take-up and release device, a first mooring tower, and a second mooring tower.

[0007] A tethered airship includes an airship body, a first load distribution mechanism is provided at a first end of the airship body, and a second load distribution mechanism is provided at a second end of the airship body, wherein the line connecting the first load distribution mechanism and the second load distribution mechanism coincides with the axis of the airship body.

[0008] The launching and retracting equipment is connected to the mooring device via a main cable. The first load distribution mechanism is used to mechanically connect with the first mooring tower, and the second load distribution mechanism is used to mechanically connect with the second mooring tower.

[0009] In some embodiments, the first load distribution mechanism and the second load distribution mechanism have the same structure, both being provided with:

[0010] The mounting component is fixed to the first or second end of the airship body;

[0011] A connector is connected to the mounting component via spokes, and the connector is mechanically connected to the first mooring tower or the second mooring tower.

[0012] In some embodiments, the mounting component is in the shape of a ring, and the ring fits around the entire arc surface of the airship body.

[0013] In some embodiments, the mounting component is secured to a pre-reserved connection point on the airship body via paracords.

[0014] In some embodiments, the connector includes:

[0015] The connecting body is connected to the mounting component;

[0016] A connecting joint is fixed to the connecting body, and the connecting joint is mechanically connected to the first tethering tower or the second tethering tower via a tethering rope.

[0017] In some embodiments, both the first mooring tower and the second mooring tower are provided with positioning mechanisms;

[0018] The connecting body has a first side facing the mounting component and a second side facing away from the mounting component. The first side of the connecting body is provided with a connecting surface that connects to the mounting component, and the second side of the connecting body is provided with a positioning surface that cooperates with the positioning mechanism.

[0019] In some embodiments, the positioning mechanism is provided with a flared opening, and the positioning surface is a conical surface that mates with the inner wall of the flared opening.

[0020] In some embodiments, the flared opening is provided with a through hole for the tethering rope to pass through.

[0021] In some embodiments, the tethering device is further provided with a clamping mechanism, the clamping mechanism being located between a first end and a second end of the airship body; the clamping mechanism includes:

[0022] Drive unit;

[0023] The clamp is connected to the drive unit and is used to lock and release the tethered aerostat under the drive of the drive unit.

[0024] In some embodiments, a transport track connecting the airship storage facility and the test site is also included, along which the tethering device moves.

[0025] Compared to the aforementioned background technology, the tethered guard system provided in this application mainly includes a tethering device and a tethered aerostat. The tethering device is equipped with a launch and retrieve device, a first tethering tower, and a second tethering tower. The tethered aerostat includes an aerostat body, with a first load distribution mechanism at the first end and a second load distribution mechanism at the second end. The connection direction between the first and second load distribution mechanisms coincides with the axis of the aerostat body. The launch and retrieve device is connected to the tethering device via a main cable. The first load distribution mechanism is used for mechanical connection with the first tethering tower, and the second load distribution mechanism is used for mechanical connection with the second tethering tower.

[0026] In existing technologies, the three-point mooring system relies on the head cone and the auxiliary cables on both sides to share the wind load. When a sudden gust of wind induces the aerostat to shift or sway, the tension of the cables on both sides cannot be adjusted synchronously. The instantaneous difference causes the tension of the cable on one side to rise sharply and concentrate on the local anchor point of the bladder. When the stress at this point exceeds the material strength, tearing occurs.

[0027] This application reduces the mooring points to the head and tail ends, and the line connecting the first load distribution mechanism and the second load distribution mechanism coincides with the axis of the airship, thereby forming two-point constraints arranged only along the axis in the head and tail direction of the moored airship; the lateral force generated by the gust can be decomposed on the airship body into synchronous pulling on the head and tail, and the bladder skin will no longer rupture due to local stress concentration, thereby eliminating the risk of tearing.

[0028] Based on the above structural and process descriptions, it can be seen that the mooring and guarding system has at least the following beneficial effects: by replacing the three-point mooring system of head cone plus auxiliary cables on both sides with collinear mooring at the head and tail, the sudden gust load is symmetrically distributed along the axis of the airship, eliminating the risk of bladder tearing caused by instantaneous overload of the single-sided cable.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] A tethered aerostat is a non-powered aircraft that relies on buoyancy generated by buoyant gas and is connected to ground anchorage facilities via a tether. As a new type of aerial work platform, tethered aerostats, with their advantages of large payload, low noise, and long-term loiter time, are playing an increasingly important role in emergency support, disaster monitoring, and low-altitude defense.

[0045] Currently, most long-term tethered airships have complicated launch and recovery procedures, requiring a large number of ground operators to coordinate operations. Furthermore, when tethered / anchored on the ground, the airship is susceptible to gusts of wind, and the auxiliary cable may suddenly experience stress exceeding the anchor point limit, which can easily cause the bladder to tear and leak air, resulting in economic and time losses.

[0046] Meanwhile, during the operation of the airship, extreme weather conditions can easily cause unpredictable damage to the airship's functions.

[0047] To address at least one of the aforementioned problems, this application provides a tethered monitoring system.

[0048] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Please refer to Figures 1 to 7 ,in, Figure 1 This is a schematic diagram of the tethered monitoring system provided in the embodiments of this application.

[0050] like Figure 1 As shown, in a first specific embodiment, the tethered guard system 100 provided by this application mainly includes a tethering device 1 and a tethered airship 2. The tethering device 1 is equipped with a launch and retrieve device 11, a first tethering tower 12, and a second tethering tower 13. The tethered airship 2 includes an airship body 21. A first load distribution mechanism 22 is provided at the first end of the airship body 21, and a second load distribution mechanism 23 is provided at the second end of the airship body 21. The connection direction between the first load distribution mechanism 22 and the second load distribution mechanism 23 coincides with the axis of the airship body 21. The launch and retrieve device 11 is connected to the tethering device 1 via a main cable 111. The first load distribution mechanism 22 is used for mechanical connection with the first tethering tower 12, and the second load distribution mechanism 23 is used for mechanical connection with the second tethering tower 13.

[0051] In existing technologies, the three-point mooring system relies on the head cone and the auxiliary cables on both sides to share the wind load. When a sudden gust of wind induces the aerostat to shift or sway, the tension of the cables on both sides cannot be adjusted synchronously. The instantaneous difference causes the tension of the cable on one side to rise sharply and concentrate on the local anchor point of the bladder (bladder fabric). When the stress at this point exceeds the material strength, tearing occurs.

[0052] This application reduces the mooring points to the head and tail ends. The line connecting the first load distribution mechanism 22 and the second load distribution mechanism 23 coincides with the axis of the airship body 21, thereby forming two-point constraints arranged only along the axis in the head and tail direction of the moored airship 2. The lateral force generated by the gust can be decomposed on the airship body 21 into synchronous pulling on the head and tail, and the bladder will no longer rupture due to local stress concentration, thereby eliminating the risk of tearing.

[0053] Based on the above structural and process descriptions, it can be seen that the mooring and guarding system 100 has at least the following beneficial effects: by replacing the three-point mooring of the head cone plus auxiliary cables on both sides with collinear mooring at the head and tail, the sudden gust load is symmetrically distributed along the axis of the airship body 21, eliminating the risk of bladder tearing caused by instantaneous overload of the cable on one side.

[0054] Optionally, the take-up and take-down device 11 uses a winch.

[0055] It should be noted that the mechanical connection between the first load distribution mechanism 22 and the first tethering tower 12, and the mechanical connection between the second load distribution mechanism 23 and the second tethering tower 13, are reflected in at least one working state of the tethering and guarding system 100.

[0056] For example, when the moored system 100 is in a ground-anchored state, the first load distribution mechanism 22 is mechanically connected to the first mooring tower 12, and the second load distribution mechanism 23 is mechanically connected to the second mooring tower 13. In addition, the moored system 100 can also be in a ground-moored state (different from the normal moored state). In the ground-moored state, the moored aerostat 2 experiences a change in altitude compared to the ground-anchored state. In the normal moored state, the moored aerostat 2 is disconnected from both the second mooring tower 13 and the first mooring tower 12.

[0057] Please continue to refer to this. Figure 2 In some embodiments, the first load distribution mechanism 22 and the second load distribution mechanism 23 have the same structure, both of which are provided with a mounting member 201 and a connecting member 202, and the connecting member 202 and the mounting member 201 are connected by spokes 203.

[0058] For the first load distribution mechanism 22, the mounting part 201 of the first load distribution mechanism 22 is fixed to the first end of the airship body 21, which can be regarded as the head end, and the connecting part 202 of the first load distribution mechanism 22 is mechanically connected to the first mooring tower 12; for the second load distribution mechanism 23, the mounting part 201 of the second load distribution mechanism 23 is fixed to the second end of the airship body 21, which can be regarded as the tail end, and the connecting part 202 of the second load distribution mechanism 23 is mechanically connected to the second mooring tower 13.

[0059] In this embodiment, the first load distribution mechanism 22 and the second load distribution mechanism 23 adopt the same configuration and are respectively fixed to the two axial ends of the airship body 21. The mounting member 201 is directly fixed to the end of the capsule body as a fixed area; the connecting member 202 is radially connected to the fixed area in the form of nodes through the spokes 203, forming a fixed area-spoke force diffusion path. When the mooring cable applies axial tension, the tension is first transmitted to the spokes 203 through the connecting member 202, and then the spokes 203 distribute the concentrated load circumferentially to the mounting member 201, and finally act uniformly on the arc surface at the end of the airship body 21, so that the mooring force that may originally be concentrated at a single point is transformed into a circumferentially distributed force, reducing the local stress peak, realizing symmetrical bearing at both ends, and providing a uniform force foundation for subsequent collinear mooring at two points.

[0060] It should be noted that this embodiment does not limit the mechanical connection method between the connector 202 and the first mooring tower 12 or the second mooring tower 13. The mechanical connection here can be achieved through the connection of the rope. When the mooring and guarding system 100 is in the ground anchoring state and the ground mooring state, the first load distribution mechanism 22 is connected to the first mooring tower 12 through the rope, and the second load distribution mechanism 23 is connected to the second mooring tower 13 through the rope. When the mooring and guarding system 100 is in the normal mooring state, it is equivalent to launching the moored aerostat 2 (the main cable that maintains the connection still exists). The rope connection between the first load distribution mechanism 22 and the first mooring tower 12 is released, and the rope connection between the second load distribution mechanism 23 and the second mooring tower 13 is released.

[0061] In some embodiments, the mounting component 201 is in the shape of a ring, and the ring fits around the entire arc surface of the airship body 21.

[0062] In this embodiment, the mounting component 201 is configured as a closed ring, which can be considered as the inner ring surface of the mounting component 201 continuously fitting with the end arc surface of the airship body 21. The moment of inertia of the ring section is much larger than that of the local bladder fabric (bladder skin), forming a circumferentially rigid reinforcing frame. When the spokes 203 apply the radial component force transmitted from the connector 202 to the ring, this force is quickly converted into tensile stress uniformly distributed along the circumference of the ring and returned to the bladder as a surface load through the continuous fitting surface. This avoids point loads acting directly on the bladder fabric fibers, significantly reduces the stress concentration factor, and ensures that the end load is uniformly diffused within a 360° range, laying the foundation for uniform force boundary conditions for two-point symmetrical mooring.

[0063] In some embodiments, the mounting component 201 is fixed to a reserved contact on the airship body 21 by parachute rope 204.

[0064] In this embodiment, the mounting component 201 is connected to the airship body 21 via parachute ropes 204. The parachute ropes 204 can be considered as continuously wrapping around the mounting component 201, locking the mounting component 201 to the bladder skin. The parachute ropes 204 are fixed to the pre-set reserved joints on the bladder skin. This flexible connection allows the ring body to automatically adjust to a position concentric with the airship axis during initial assembly, eliminating rigid assembly deviations. When the mooring force is transmitted to the ring body through the spokes 203, the parachute ropes 204 first undergo tensile deformation, attenuating the sudden peak force into a gradual tension before being transmitted to the bladder skin, thus playing a mechanical filtering role and preventing instantaneous impact from directly acting on the bladder fabric. At the same time, it retains the ring body's function of evenly distributing circumferential loads, achieving a dual effect of rigid-flexible transition and load buffering.

[0065] Please continue to refer to this. Figure 2 In some embodiments, the connector 202 includes:

[0066] The main body 2021 is connected to the mounting component 201;

[0067] The connecting joint 2022 is fixed to the connecting body 2021, and the connecting joint 2022 is mechanically connected to the first mooring tower 12 or the second mooring tower 13 through the mooring rope 205.

[0068] In this embodiment, the connector 202 adopts a split design: the connecting body 2021 is rigidly connected to the mounting component 201 via spokes 203, extending outward along the axis of the airship body 21 to form the main trunk for load transmission; the connecting joint 2022 is located at the outer end of the connecting body 2021 and is connected to the mooring rope 205 via holes. After the mooring rope 205 introduces the tower end tension into the connecting joint 2022, the tension is transmitted along the axial direction of the connecting body 2021, and then diffused to the annular mounting component 201 via the spokes 203, completing the load conversion from point to surface; this structure concentrates the high stress area in the metal connecting body 2021, and the bladder only bears the homogenized surface load, avoiding the fibers directly bearing the joint friction and bending, thus improving the reliability and maintainability of the connection.

[0069] In some embodiments, both the first mooring tower 12 and the second mooring tower 13 are provided with a positioning mechanism 14;

[0070] The connecting body 2021 has a first side facing the mounting member 201 and a second side facing away from the mounting member 201. The first side of the connecting body 2021 is provided with a connecting surface 20211 connected to the mounting member 201, and the second side of the connecting body 2021 is provided with a positioning surface 20212 that cooperates with the positioning mechanism 14.

[0071] In this embodiment, the positioning mechanism 14 is located on the opposing sides of the first mooring tower 12 and the second mooring tower 13. Specifically, the first positioning mechanism 14 is located on the side of the first mooring tower 12 facing the second mooring tower 13, and the second positioning mechanism 14 is located on the side of the second mooring tower 13 facing the first mooring tower 12. As the mooring rope 205 gradually tightens, the connecting body 2021 is pulled towards the positioning mechanism 14. The positioning surface 20212 first contacts the reference contour of the positioning mechanism 14, forming initial alignment. As the mooring rope 205 continues to contract, the positioning surface 20212 slides along the reference contour, automatically correcting the pitch and yaw angles of the connecting body 2021 until the two surfaces are fully aligned, achieving precise positioning where the axis of the airship body 21 coincides with the reference axis of the tower. This process decomposes the cable tension into axial mooring force and normal pressure on the positioning surface, ensuring the spatial attitude stability of the airship in its anchored state and avoiding additional installation and adjustment procedures, thus improving the efficiency of system deployment and retrieval.

[0072] Please continue to refer to this. Figure 3 In some embodiments, the positioning mechanism 14 is provided with a flared opening 141, and the positioning surface 20212 is a conical surface that mates with the inner wall of the flared opening 141.

[0073] In this embodiment, the inner wall of the flared opening 141 of the positioning mechanism 14 is a conical surface, and the positioning surface 20212 on the second side of the connecting body 2021 is machined into a conical surface with the same cone angle. When the mooring rope 205 is tightened, the conical positioning surface 20212 slides in along the conical generatrix of the flared opening 141, generating a radial component force at the moment of contact, automatically zeroing the lateral offset of the connecting body 2021. As the cable tension increases, the two conical surfaces transition from initial line contact to surface contact, and the contact stress is evenly distributed. At the same time, the axial component force firmly pulls the end of the airship body 21 toward the tower, achieving self-locking centering. This conical surface mating structure allows for a certain initial deviation within the manufacturing tolerance range, reducing the requirements for machining and assembly precision, and maintaining uniform wear during repeated deployment and retraction, thus extending the life of the positioning pair.

[0074] In some embodiments, the flared opening 141 is provided with a through hole 142 for the mooring rope 205 to pass through.

[0075] In this embodiment, a through hole 142 is formed in the center of the bell mouth 141. The mooring rope 205 extends from the winch end inside the tower to the connecting joint 2022 through the through hole 142. The diameter of the through hole 142 is larger than the maximum outer diameter of the mooring rope 205 and leaves a swing gap, so that the cable can swing freely in the hole when the aerostat is disturbed by gusts of wind, avoiding sharp edge friction with the bell mouth 141. Since the through hole 142 is located on the axis of rotation of the conical surface, the cable is immediately coaxial with the connecting joint 2022 after it passes through, ensuring the symmetrical force of the conical positioning pair. At the same time, the through hole 142 fixes the entry point of the cable at the geometric center of the conical surface, preventing the cable from deflecting and generating additional bending moment, ensuring that the contact pressure distribution between the positioning surface 20212 and the bell mouth 141 is uniform, and maintaining the stability and repeatability of the self-centering function.

[0076] Please continue to refer to this. Figure 4 In some embodiments, the tethering device 1 is further provided with a clamping mechanism 15, which is located between the first end and the second end of the airship body 21; the clamping mechanism 15 includes:

[0077] Drive unit 151;

[0078] The clamp 152 is connected to the drive unit 151. The clamp 152 is used to lock and release the tethered airship 2 under the drive of the drive unit 151.

[0079] In this embodiment, the clamping mechanism 15 is located in the middle section of the airship body 21 between the first mooring tower 12 and the second mooring tower 13. Its drive unit 151 is fixed to the support frame of the mooring device 1, and the clamping frame 152 opens and closes radially under the linear or rotary output of the drive unit 151. Before the system transitions from the launch state to the mooring or transport state, the drive unit 151 outputs thrust, causing the clamping frame 152 to close inward, making multi-point contact with the airship body 21's bladder from the circumference, forming a circumferential constraint. This constraint firmly connects the middle section of the airship body 21 to the mooring device 1, effectively suppressing the swaying and vibration of the bladder under strong winds or transport vibrations, and reducing the fatigue load on the head and tail load distribution mechanism. When launch is required, the drive unit 151 reverses its action, and the clamping frame 152 quickly opens, releasing the bladder, thus achieving automated and rapid state switching.

[0080] Alternatively, the drive unit 151 may employ an electric actuator.

[0081] In one specific embodiment, the radial dimension of the mounting member 201 is larger than the radial dimension of the connector 202. The two ends of the spokes 203 are connected to the inner side of the mounting member 201 and the outer side of the connector 202. The spokes 203 are circumferentially distributed and extend radially in the axial direction. The mounting member 201, the connector 202 and the spokes 203 form a conical integral structure, while the connector 202 is a smaller conical structure.

[0082] Please continue to refer to this. Figure 5 In some embodiments, a transport track 3 is also included, connecting the airship storage 01 and the test site 02, along which the tethering device 1 moves.

[0083] In this embodiment, the transport track 3 is rigidly laid between the airship storage 01 and the test site 02, forming a continuous guide path with controlled straight lines or curvature. The bottom of the mooring device 1 is equipped with a walking assembly that matches the track cross-section, allowing the entire moored airship 2 to reciprocate along the transport track 3 in a retracted state. When extreme weather warnings are issued or the mission is completed and rapid storage is required, the mooring device 1, after being released from anchor, can immediately start the walking drive to move the airship body 21 into the storage silo while maintaining a head-to-tail constrained posture, avoiding on-site disassembly and hoisting procedures. At the same time, the track guidance ensures that the angle between the airship axis and the wind direction remains constant during movement, preventing lateral wind forces from causing the airship to swing and the structure to collide, thus achieving safe and efficient site transfer.

[0084] Alternatively, the mooring device 1 may be a rail-mounted mooring vehicle, on which a launch and take-up device 11, a first mooring tower 12, and a second mooring tower 13 may be installed.

[0085] Please continue to refer to this. Figure 6 and Figure 7In one specific implementation, the usage process of the tethered guard system 100 is described as follows.

[0086] When the tethered airship 2 is in operation, the door of the airship storage 01 is opened, the motion switch is activated, and the tethered device 1 is moved along the transport track 3 to a suitable position in the test site 02.

[0087] Start the drive unit 151 to release the tethered airship 2 from the clamp 152.

[0088] Start the take-up and release device 11 to release the main cable 111. The length is determined according to the actual site conditions.

[0089] Start the winches of the first mooring tower 12 and the second mooring tower 13 to release the mooring rope 205 and achieve the ground mooring state. At this time, the mooring aerostat 2 is moored by the first load distribution mechanism 22 and the second load distribution mechanism 23, and achieves the two-point ground mooring state.

[0090] Continue to start the launch and take-up equipment 11, release the main cable 111, and at the same time release the mooring rope 205 until the mooring rope 205 is separated from the first mooring tower 12 and the second mooring tower 13 and reaches the predetermined height, realizing the normal mooring state of the moored aerostat 2, and the moored aerostat 2 starts to work.

[0091] During retrieval, the take-up and release device 11 is activated to retrieve the main cable 111 until the tethering ropes 205 of the first load distribution mechanism 22 and the second load distribution mechanism 23 just touch the ground.

[0092] The mooring rope 205 is retrieved by the winches of the first mooring tower 12 and the second mooring tower 13, and the main cable 111 is retrieved at the same time, so that the mooring rope is on the ground.

[0093] Continue to start the winches of the first mooring tower 12 and the second mooring tower 13 to retrieve the mooring rope 205 until the first load distribution mechanism 22 and the second load distribution mechanism 22 enter the horn opening 141 of the positioning mechanism 14, and reach the ground anchoring state.

[0094] In case of extreme weather (strong winds, heavy rain, lightning, etc.) or if it is necessary to move the tethered airship 2 into the airship storage 01, start the drive unit 151 to make the clamp 152 lock and tether the airship 2, and then start the tethering device 1 to move along the transport track 3 to move the tethered airship 2 into the airship storage 01 as a whole.

[0095] Therefore, the tethered guard system 100 has the following advantages.

[0096] The first load distribution mechanism 22 and the second load distribution mechanism 23 are used for two-point tethering and fixing, replacing the commonly used three-point tethering and fixing with a head cone and two side auxiliary tethering and fixing. The tethering rope 205 distributes the tension evenly to the load-bearing point through the first load distribution mechanism 22 and the second load distribution mechanism 23, avoiding the situation where the bladder is torn due to single-point stress on the auxiliary cable under extreme working conditions.

[0097] A clamping mechanism 15 is added so that, during transportation or in strong winds, the clamping frame 152 is driven to retract by the drive unit 151 to clamp the airship body 21, thereby preventing the first load distribution mechanism 22 and the second load distribution mechanism 23 from being subjected to excessive force and damaging the airship body 21.

[0098] Using transport track 3 for ground transportation can increase the overall weight of tethered device 1, improve the stability of the ground system in flight, and at the same time restrict the degree of freedom of movement of tethered device 1, making it easier to achieve automated control.

[0099] Compared to the number of operators required for conventional tethered airships, this solution can reduce the number of operators by at least 2.

[0100] The accompanying airship storage 01 can effectively prevent damage to the tethered airship 2 caused by extreme weather conditions (such as storms, lightning, and heavy rain).

[0101] In summary, by utilizing the above-mentioned technical solution of this application, through the automatic movement of the tethering device 1 along the transport track 3, the two-point ground tethering scheme at the head and tail, and the automatic locking and releasing of the clamping mechanism 15, the tethered airship 2 can be semi-automatically switched between states such as launch, recovery, ground tethering, ground anchoring, and transportation, thereby reducing the number of operators and mitigating the impact of extreme weather on the tethered airship 2.
