Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for adjusting the buoyancy of an airship and a buoyancy adjustment device thereof that eliminates the need to release buoyant debris or use a last.

Airships that obtain their buoyancy from buoyancy gas such as hydrogen gas, hydrangea gas, or helium gas need to adjust their buoyancy to accommodate changes in temperature, atmospheric pressure, and weight changes due to fuel consumption. The buoyancy of the airship is adjusted by releasing buoyant gases such as hydrogen and helium, and by using ballast such as water or sand.

However, the above-mentioned airships have problems such as a reduction in payload due to the possession of ballast and a loss of valuable helium due to the release of buoyant gas, and since these adjustments are irreversible, there is a limit to the number of times they can be adjusted. There was a drawback.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks in adjusting the buoyancy of an airship. The object of the present invention is to provide a buoyancy adjustment method and device for the same.

That is, the buoyancy adjustment method of the present invention uses a cooling element made of thermoelectric material to transfer the buoyant gas volume in the gas bag of an airship to each heat pipe provided inside the gas bag and on the outside air side. The buoyancy adjustment device is characterized by increasing or decreasing the buoyancy by thermal control, and the buoyancy adjustment device includes a waste bag side heat pipe with a gas bag side heat transferer installed in the gas bag of the airship, and a gas bag side heat pipe installed on the outside air side. and an outside air side heat transfer pipe having an outside air side heat transfer device connected to the gas bag side heat exchanger plate and the outside air side heat exchanger plate of the heating/cooling element made of thermoelectric power, respectively, and It is constructed by providing the heating/cooling element with a controller that allows current to flow in a forward or reverse direction in a switchable manner.

An embodiment of the present invention will be described below with reference to the drawings, which are schematic configuration diagrams of an airship in an embodiment of the present invention. In the drawings, 1 is the outer shell of the airship, 2 is a gas bag, and 6 is a Floating gas such as helium, 4 is sunlight, 5 is a solar cell, 6 is a heating and cooling element, 7 is a gas bag side heat exchanger plate, 8 is an outside air side heat exchanger plate, 9
is the heat vibrator on the gas bag side, 10 is the P1 pipe on the outside air side,
11 is a gas bag side heat transfer device, and 12 is an outside air side heat transfer device.

``An outside air side heater having a gas bag side heat vibrator 9 extending south of the gas bag side heat transfer device 11 provided in the waste bag 2 mentioned above, and an outside air 1p11 heat transferer 12 provided on the outside air side] The pipe 10 is B12-Te3. Pb −Te +B
+2Te3 Sb2Te3. B'2Te3 'B'
The heating and cooling element B, which is composed of a thermoelectric device 2 and 3, is connected to the gas bag side heat transfer plate 7 and the outside air (till heat transfer plate 8), respectively, and the heating and cooling element 6 is connected to the air in the forward or reverse direction. Controller 13 that can switchably flow current
has been established.

Therefore, when increasing the buoyancy in the buoyancy adjustment device of the embodiment of the present invention having the above configuration, the heating/cooling element 6
When a current is passed in the forward direction, the waste bag side heat exchanger plate 7 generates heat,
The outside air side heat exchanger plate 8 absorbs heat.

It is transmitted from the gas bag side heat transfer device 11 to the floating gas B, and the temperature of the floating gas B increases, and as a result of the volume increase due to expansion, the buoyancy of the airship increases.

On the other hand, on the heat absorption side, the heat obtained from the outside air side heat transfer device 12 is transmitted to the outside air side heat exchanger plate 8 via the outside air side heat pipe 10.

Incidentally, during the above operation, stirring is performed by the fan 19 in order to quickly and uniformly change the temperature of the gas 6 in the waste bag 2.

Further, the above-mentioned switching of the current flow direction is performed by a controller 13 having a built-in relay switch.

Next, when reducing the buoyancy, the temperature of the buoyant gas B decreases due to the opposite effect of flowing a current in the opposite direction to the heating/cooling element B, and the volume decreases, resulting in a decrease in buoyancy.

As described above, the buoyancy adjustment device of the present invention can be used to adjust the increase or decrease of buoyancy in small steps. If not, or if the condition after adjustment lasts for a long time, in this embodiment, the buoyancy can also be adjusted using the 1B, the compressor 18, the gas tank 17, and the valve 16 connected to the gas bag 2.

In other words, when reducing buoyancy, the gas compressor 18
If you want to increase the buoyancy by sending the floating debris 6 in the gas bag 2 to the gas tank 17, open the valve 16 and transfer the floating debris 6 from the gas bag 2 to the gas tank 17.
By sending the levitation gas 3 of 7 to the gas bag 2, the gas bag 2
It is possible to significantly increase or decrease the body j('l) of floating debris 3 inside.

The power source 1j2 for operating each device in the airship of the above embodiment is mainly installed on the outer shell-upper surface of the airship 1''
It is assumed that the gravity is obtained from the sunlight 4 by the solar cell 5 and stored in the storage 14, and the shortfall is made up by the Kamisuke tungen 15.

Therefore, in the above 1, the buoyancy Ah' of the own embodiment, the buoyancy gl of the device in section I and the grandchild device/this airship are adjusted by the heating/cooling device using the Peltier effect of the present invention and the temperature of the buoyant gas by the heat pipe. This is done by adjusting the buoyancy, but when reducing the buoyancy, a gas compressor connected to the gas bag sends buoyancy gas to the gas tank.
When increasing the buoyancy, a valve is opened to send the floating debris in the gas tank to the gas bag. I try to ask from l■.

As a result, the buoyancy adjustment device for an airship to which the present invention is applied can quickly and reversibly adjust buoyancy over a wide range without releasing buoyancy gas or using ballast.

In particular, the buoyancy adjustment device of the present invention has the advantage of being able to finely adjust the buoyancy by controlling the height of the levitation gas using a heating/cooling element using a Beltier//JJ filter, a heat pipe, and a buoyant gas.
