Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a mooring device for an airship, and in particular to an airship that can always moor an airship floating at a landing site in a fixed position and automatically perform the mooring operation. Regarding a mooring device.

[Prior Art] Relatively small airships that fly using helium gas or the like as a buoyancy source are used for advertising or special purposes. In general, airships rely on wind power to fly, and when taking off and landing, the nose, which forms the tip of the hull, is adjusted to face the windward, and the ballast is adjusted while the hull is moved up and down.
Or move in the front and back direction to ascend and descend.

[Problems to be Solved by the Invention] Thus, in order to take off and land an airship that relies on wind power to fly from a predetermined location, a dedicated landing pad is required.

Conventionally, a mooring mast is installed upright on the ground, and the nose of the airship is moored to this mooring mast, thereby making it possible for the airship to take off and land. In this case, the hull of the airship is moored while floating around the mooring mast in response to changes in wind direction.

For this reason, there has conventionally been a problem in that a sufficient area for mooring the airship around the mooring mast must be secured at the airship landing site.

Furthermore, when mooring an airship to a mooring mast, it is necessary to tie a mooring cable hanging down from the nose of the ship to the mooring mast and to hold down a gondola or the like located at the bottom of the ship. Therefore, there was a problem in that a lot of effort had to be spent to accomplish these tasks.

Therefore, airship landing pads are located far away from crowded areas. For this reason, there has been a problem in the practical application and commercialization of medium-sized or larger airships intended for passenger ships.

The present invention was created to effectively solve these problems, and is an airship mooring device that can reduce the site area of an airship launch site and facilitate the work of mooring an airship at the airship landing area. The purpose is to provide

[Means and effects for solving the problem] A mooring cable that hangs down from the nose of the airship floating above the airship to the airship, and a mooring cable that is rotatably provided at the airship and is sufficient to moor the airship. a mooring mast, which is provided on the launch and landing platform at a position eccentric from its center of rotation, for mooring the airship with the nose of the airship directed upwind; and the mooring mast. An engagement wire extends from the mooring mast, waits upwind, and engages and ties the hanging mooring rope, and an engagement wire provided on the mooring mast and engages with the mooring rope is inserted into the mooring mast. and a mooring cable pulling means for engaging the nose part with the upper end of the mooring mast, and the mooring cable hanging from the airship is hooked and tied to the engagement wire waiting upwind.
The mooring ropes and engagement wires tied together are drawn into the mooring mast to draw the nose of the airship to the mooring mast.

Specifically, the mooring line 4 has a hook member 9 at its lower end. As shown in FIG. 2, this hook member 9 is constituted by a specially shaped cross hook which has claws 9a to prevent detachment and is spread out on all sides so that it can easily catch the engagement wire with its own blade.

A circular take-off and landing pad 5 is provided at the take-off and landing place 1 for the airship 2. As shown in FIG. 3, the landing and departure table 5 is mainly composed of a fixed table 10, a rotary table 11, and a roller 12' sandwiched between them.

The rollers 12 are supported by a fixed base 10 via a bearing base 13 and are aligned along the circumferential direction of the rotary table 11.

Further, the rollers 12 are connected to each other via a chain 14 and are rotationally driven by a motor 15.

Further, a mooring mast 6 is provided on the rotary table 11 of the departure and landing platform 5 so as to stand apart from the center of rotation thereof. This mooring mast 6 is configured to moor the nose portion 3 of the airship 2 facing upwind by the rotation of the landing pad 5. Therefore, the landing platform 5 rotates to direct the mooring mast 6 upwind in response to changes in wind direction.

An engagement wire 7 extends from the upper end of the mooring mast 6 so as to be freely retractable.

The engagement wire 7 is formed in an endless shape, and is stretched across the upper end of the mooring mast 6 and the landing platform 5 and is tensioned. In this embodiment, the mooring mast 6 side is gradually expanded from the landing platform 5 side. That is, the engagement wire 7 is spread out through the eye plate 16 into a triangular shape forming three sides.

An engagement claw portion 17 for deploying the engagement wire 7 into a triangular shape is formed on the departure and landing platform 5, and this engagement claw portion 17 is provided at a position opposite to the mooring mast 6. Also,
As shown in FIG. 5, an open slit 18 facing the upper end of the mooring mast 6 is formed in the engagement claw portion 17, and the engagement wire 7 is inserted into this slit 18. ing. Therefore, after the hook member 9 of the mooring line 4 engages with the engagement wire 7, if the engagement wire 7 is pulled into the mooring mast 6, the engagement wire 7 will not come off the engagement claw portion 17. Accordingly, the mooring cable 4 and the engagement wire 7 are configured to be tied together.
