Description

[0001]
[Industrial application fields]
The present invention relates to a method and apparatus for mooring an airship at a fixed point during weather observation, and is an improved invention relating to a moored airship that allows a propellant fuel supply to an onboard engine and a fuel supply device to stay at a fixed point for a long time.
[0002]
[Prior art]
Conventionally, a mooring airship for weather observation has not been equipped with a propeller or other propulsion device, and when moored, it is easily affected by crosswinds in the sky, so it is not easy to stay at a fixed point.
[0003]
For this reason, when it was intended to stay at a fixed point for a long time in weather observation, etc., a large engine and other propulsion devices were newly installed on the moored airship and a considerably large fuel tank was installed. .
[0004]
[Problems to be solved by the invention]
However, conventional moored airships are installed in airships from the beginning because they consume a large amount of fuel to stay at a fixed point, and space for fuel tanks is secured in advance at the design stage in order to moor a fixed point for a long time. The size of the airship itself had to be increased, which was a big problem in the design of the airship itself.
[0005]
Even if a large amount of fuel is loaded, the fuel must be refilled when the fuel is consumed, so it must be lowered to the ground. Therefore, long-term continuous mooring is impossible.
[0006]
Furthermore, there is a drawback that it is very difficult to ensure stability at a fixed point because the weight of the hull itself becomes very light due to the consumption of the fuel mounted on the moored airship and the buoyancy increases.
[0007]
Therefore, the present invention is capable of continuously staying at a fixed point for a long time by installing a gas engine as a propulsion device on a moored airship moored at a fixed point and supplying this fuel gas from the ground through a gas pressure hose. The purpose is to provide a moored airship.
[0008]

[0011]
Details of the airship 2 moored at a fixed position will be described below. The airship 2 is moored at a fixed point A, and the shape of the hull 2a of the airship 2 is formed in a substantially elliptical shape.
[0012]
Of course, the shape of the hull 2a of the airship 2 does not necessarily have to be substantially elliptical, and may be other shapes. For example, a spherical shape, a cylindrical shape, a rectangular parallelepiped shape, a cubic shape, or other shapes may be used.
[0013]
As shown in FIG. 1, a propulsion unit 3 and a transceiver 5 are installed outside the hull 2a. The propulsion unit 3 is installed in front of the lower part of the hull 2a, and the transceiver 5 is installed in the rear of the propulsion unit 3.
[0014]
At the rear of the hull 2a, an upper vertical wing 2b, a lower vertical wing 2c, a left horizontal wing 2d, and a right horizontal wing 2e are provided to balance the hull 2a when the hull 2a is moored at a fixed position. It has been.
[0015]
The propulsion device 3 attached to the lower part of the hull 2a incorporates a drive source. The driving source is an electric motor or an engine 3a driven by gas. There is a rotating shaft 3c that is rotated by an electric motor, an engine, or the like as the driving source, and a propeller 3b is attached to the rotating shaft 3c. The hull 2a of the airship 2 moves by the rotation of the propeller 3b.
[0016]
A mounted radio transceiver 5 having a structure capable of wireless communication is attached to the rear of the propulsion unit 3 attached to the hull 2a of the airship 2. Reference numerals 5 a and 5 b are antennas for transmitting or receiving signals from the on-board radio transceiver 5 or the terrestrial radio transceiver 8.
[0017]
A navigation device 4 is built in the hull 2 a of the airship 2. The navigation device 4 receives a signal transmitted from the ground radio transmitter / receiver 8 by the on-board radio transmitter / receiver 5 mounted on the airship 2, and stays at a predetermined fixed point (position) according to the instruction of the content of the received signal. In this way, the output of the engine 3a as a drive source is controlled.
[0018]
As shown in FIG. 1, a fuel supply device 6, a winch 7, and a ground radio transceiver 8 are installed on the ground. On the ground, a fuel supply device 6 that supplies fuel to an engine 3a that is a drive source of a propulsion device 3 installed in the lower part of the hull 2a of the airship 2 is installed.
[0019]
The fuel container 6a of the fuel supply device 6 includes a pressure gauge 6b for measuring the pressure of fuel such as gas and an open / close valve 6c for supplying fuel. A hose 3 d connected to an engine 3 a attached to the hull 2 a of the airship 2 is connected to a connecting member 6 d of the fuel supply device 6.
[0020]
A winch 7 is installed on the ground. A mooring rope 7 a is wound around the winch 7, and the mooring rope 7 a is moored on the hull 2 a of the airship 2.
[0021]
In addition to the fuel supply device 6 and the winch 7, a ground radio transceiver 8 is installed on the ground. Reference numeral 8 a denotes an antenna, which is an antenna for transmitting a signal from the terrestrial radio transceiver 8 or receiving a signal transmitted from the on-board radio transceiver 5.
[0022]
In the method of mooring the airship 2 at a fixed position (fixed point) in the sky, the hose 3d for supplying gas fuel and the mooring rope 7a are attached, and the airship 2 is lifted to the sky by itself and adjusted to stop the mooring rope 7a. .
[0023]
When the position of the airship 2 stopped in the sky is not stopped at the desired position,
An instruction content signal is transmitted from the antenna 8a of the ground radio transceiver 8 to the navigation device 4 attached to the hull 2a.
[0024]
The on-board radio transceiver 5 receives the signal of the instruction content, and the on-board radio transceiver 5 transmits the received signal to the navigation device 4, and the navigation device 4 sends the engine 3a of the propulsion device 3 according to the signal content. The propeller 3b is rotated, moved to a desired fixed point A position, and stopped.
[0025]
The hose 3 d connected to the fuel supply device 6 is connected to an engine 3 a attached to the lower part of the hull 2 a of the airship 2.
Even if a strong wind blows, the hose 3d is firmly connected so that the engine 3a and the fuel supply device 6 connected to each other are not detached.
[0026]
Even if the hose 3d is detached from the fuel supply device 6 due to a strong wind, the fuel container 6a of the fuel supply device 6 is prevented from leaking outside by recognizing the state where the hose 3d is detached. Safety devices are incorporated.
[0027]
The hull of the airship 2 is subjected to pressure through a rubber-like tube 3d connected to the connecting member 6d by opening an open / close valve 6c attached to the upper part of the fuel supply device 6 to the airship above the airship supplied to the engine 3a. It feeds into the fuel tank mounted on 2a.
[0028]
The fuel supply device 6 is provided with a pressure gauge 6b. The gauge of the pressure gauge 6b can be checked, and fuel can be sent to the engine 3a attached to the airship 2 in the sky at an appropriate pressure at all times. It has a structure.
[0029]
In addition, the fuel supply device 6 is configured to automatically stop when the supply of fuel to the engine 3a of the propulsion device 3 attached to the airship 2 stopped at a fixed point in the sky is completed. With such a structure, a necessary amount of fuel can be constantly supplied to the engine 3a of the propelling device 3 of the airship 2.
[0030]
By automatically calculating the stop position, altitude, etc. in the sky by a computer built in the navigation device 4 provided in the hull 2a, it is possible to stop at the most suitable position for observation.
[0031]
Further, when the stop position does not automatically stop at the target stop position, when the signal indicating the best stop position is transmitted from the terrestrial radio transceiver 8, the on-board radio transceiver 5 receives the signal, The stop state of the airship 2 can be controlled.
[0032]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
First, the airship does not need to be refilled and can be moored continuously for a long period of time, and the fuel can be filled on the water, even on the ground, if there is a fuel device.
[0033]
Secondly, only a minimum fuel tank space is required at the design stage. Therefore, the design of the hull of the airship can be optimized, and the manufacturing cost of the hull is reduced.
