Description

Technical Field

[0001] This invention belongs to the field of tethered airships and relates to an automatic recovery mechanism, specifically an automatic recovery and anchoring device for tethered airships. Background Technology

[0002] Tethered airships, as a near-space levitation platform, rely on the lift-generating gas, such as hydrogen or helium, that fills their bladders. With a density less than air, they have the characteristics of taking off, hovering, or flying. Depending on different requirements, tethered airships can carry different equipment and are widely used in fields such as communications, atmospheric and geographical environment monitoring, security monitoring of large-scale events and gatherings, military reconnaissance, electronic information warfare, and tourism.

[0003] Although tethered airships have advantages such as simple operation and low equipment cost, in practical applications, the recovery process requires a large number of personnel, which brings great inconvenience. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes an automatic retrieval and anchoring device for moored airships, which effectively solves the problems of complex operation and a large number of personnel involved in the retrieval process of existing moored airships.

[0005] The present invention relates to an automatic tethered airship recovery and anchoring device, comprising a support mechanism and a photoelectric slip ring recovery mechanism mounted thereon.

[0006] The support mechanism has a horizontally arranged connecting plate at the top for fixing the photoelectric slip ring recovery mechanism; the support mechanism is welded and fixed to the anchoring platform; and a limit switch is installed on the support mechanism.

[0007] The photoelectric slip ring recovery mechanism includes a bowl-shaped retainer, a contact baffle, and a photoelectric slip ring. The bottom surface of the bowl-shaped retainer is fixedly mounted to the connecting plate; a groove is pre-drilled in the bowl-shaped retainer, through which the contacts of the limit switch pass, exposed outside the groove. A through hole is located at the center of the bottom of the bowl-shaped retainer for a cable to pass through. The contact baffle is mounted on the photoelectric slip ring, which is fixed to the cable. When the photoelectric slip ring moves the contact baffle downwards, it reaches the groove and touches the contacts of the limit switch, sending a power-off signal and de-energizing the equipment.

[0008] Therefore, once the airship is fully inflated, it automatically launches the recovery and anchoring device. Since the cable is connected to the moored airship via a winch, ground personnel can start the motor or remotely control the motor to begin operation when the recovery begins. The cable is retracted, causing the photoelectric slip ring and the moored airship to descend continuously until the contact baffle on the photoelectric slip ring contacts the limit switch, at which point the winch automatically stops and cuts off the power, thus completing the recovery of the moored airship.

[0009] The present invention has the following advantages:

[0010] 1) The present invention provides an automatic retrieval and anchoring device for moored airships, which improves the automation level of moored airship deployment and makes up for the problems of complex deployment and retrieval procedures and high manpower requirements.

[0011] 2) The automatic retrieval and mooring device for tethered airships of the present invention achieves automatic stopping of the winch by installing a travel limit switch on the automatically retrieved mooring frame and cooperating with a photoelectric slip ring installed on the cable; thereby, the automatic retrieval and mooring device for airships has the characteristics of cable collision prevention, reliable installation of the retrieval structure, and simple operation by personnel.

[0012] 3) The automatic retrieval and mooring device for tethered airships of this invention, through the design of a retainer, allows the photoelectric slip ring to fall into the retainer, thus realizing the retrieval of the photoelectric slip ring. This further compensates for the problems of complex photoelectric slip ring retrieval procedures and high manpower requirements, reduces personnel operation procedures, and improves personnel safety. It reduces human intervention and improves the reliability and safety of the facility. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] The present invention relates to an automatic tethered airship recovery and anchoring device, comprising a support mechanism 15 and a photoelectric slip ring recovery mechanism.

[0025] The support mechanism 15 serves as the main structure of the entire recovery mooring device, and includes two long support frames 1, two short support frames 2, four support round tubes 3, a transition plate round piece 4, a connecting plate 5, a cable roller 9, a limit switch transition sheet metal 11, and a cable roller support sheet metal 10.

[0026] The two long support frames 1 form the main support structure and are arranged in parallel. Two short support frames 2 are vertically welded to the long support frames 1. The bottom ends of four support tubes 3 are welded to four points between the long and short support frames 1. The top ends of the four support tubes 3 are coaxially welded to and fixed to the adapter plate disc 4. The adapter plate disc 4 has a threaded hole at its center, which mates with countersunk bolt holes at the four corners of the rectangular connecting plate 5. Tightening the bolt threads secures the adapter plate disc 4 to the connecting plate 5.

[0027] At the center of the lower part of the two short support frames 2, two sets of symmetrical cable roller support sheet metal 10 are welded, with the cable roller 9 fixed in the middle; the cable roller 9 is perpendicular to the two short support frames 2 and parallel to the two long support frames 1. The two sets of cable rollers form a restricted area for the cable to prevent the cable from swinging freely.

[0028] like Figure 3 As shown, the limit switch adapter sheet 11 is fixed to the bottom surface of the connecting plate 5 by bolts; the limit switch adapter sheet 11 has a connection hole, which corresponds to the threaded hole on the limit switch 12. The two work together to connect the limit switch 12 and the limit switch adapter sheet 11 by bolts; at the same time, holes are drilled in the connecting plate 5 so that the contacts of the limit switch 12 can pass through the holes in the connecting plate.

[0029] The support mechanism 15 of the above structure adopts a welded mechanism plus a bolted connection mechanism, such as Figure 2 As shown, the welded mechanism is the support mechanism 15, in which two rectangular steel bars are welded to the main frame of the anchoring platform. The bolted connection mechanism is the photoelectric slip ring recovery mechanism, which is fixedly installed on the support mechanism by bolts.

[0030] The photoelectric slip ring recovery mechanism includes a bowl-shaped retainer 6, a touch baffle 7, and a photoelectric slip ring 8.

[0031] The cup-shaped retainer 6 has a cup-shaped structure with threaded holes at its bottom in a circular array. Simultaneously, the connecting plate 5 has countersunk bolt holes corresponding to these threaded holes. The two work together to fix the cup-shaped retainer 6 to the connecting plate 5 using bolts. A groove is pre-reserved on the bottom surface of the cup-shaped retainer 6, with openings on the bottom surface of the groove corresponding to the openings on the connecting plate. The contacts of the limit switch 12 pass through both the openings on the connecting plate and the openings on the bottom surface of the groove, and are located within the groove. Additionally, a through hole is located at the center of the bottom of the cup-shaped retainer for the cable to pass through.

[0032] The touch baffle 7 has bolt holes and is mounted on the photoelectric slip ring 8, which is fixed to the cable and located at the center of the bowl-shaped retainer 6. When the photoelectric slip ring 8 moves the touch baffle 7 downwards, the bowl-shaped structure guides the touch baffle 7 into the groove, triggering the contact of the limit switch 12. The limit switch 12 then sends a power-off signal, cutting off the power to the equipment. Simultaneously, the photoelectric slip ring 8, positioned within the bowl-shaped structure and positioned by the groove to touch the baffle 7, is retracted.

[0033] One end of the cable is connected to the winch motor on the ground, and the other end passes through the cable roller 9, the connecting plate 5 and the cup-shaped retainer in sequence, and then passes through the photoelectric slip ring 8. It is divided into several strands by the bundled plate, and the top of each strand of the cable is fixedly connected to the tethered airship by welding patch.

[0034] Therefore, once the airship is fully inflated, it automatically launches the photoelectric slip ring 8. Since the cable is connected to the tethered airship via a winch, ground personnel can start the motor or remotely control the winch motor to begin retrieval. The winch then retrieves the cable, causing the photoelectric slip ring 8 and the tethered airship to descend continuously until the touch baffle 7 on the photoelectric slip ring 8 contacts the limit switch 12, at which point the winch automatically stops and cuts off power, thus completing the retrieval of the tethered airship.

[0035] The automatic mooring recovery device of this invention can automatically recover the tethered airship that has been launched into the air via a cable, which improves the automation level of tethered airship deployment and makes up for the problems of complex deployment and retrieval procedures and high manpower requirements, ensuring that the needs of tethered airship deployment convenience and reliability are met.
