Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collection balloon which can be used for various purposes including a transportation system for materials and the like. The present invention relates to a novel collective balloon which is excellent in adjustment, storage property, mooring property, mobility and gas filling property.

[0002]

2. Description of the Related Art A conventional balloon is used not only as a self-propelled device as seen in an airship, but also for weather observation and photography. Since the balloon itself has no exhaust or noise pollution, it is a natural environment-friendly energy-saving system, a futuristic transport system using free space, a rescue evacuation system, a tourist entertainment system, an observation and measurement system, agriculture or fishing. It is expected to be used in various fields such as application to medical devices.

Conventionally known balloons are mainly composed of a single large balloon filled with helium gas.
It is customary to cover the nets required for the large balloons, and to form pits for loading observations and various equipment. The lift is adjusted by adjusting the size of the balloon or filling and discharging gas into the balloon.

[0004]

As described above, balloons do not have various types of pollution, and are expected to be used in many fields as an energy-saving system. Many problems remain to be improved.

For example, there is a countermeasure against the wind, and it is necessary to ensure that the balloon has a lift sufficient to withstand the wind speed. For that purpose, it is necessary to fill the balloon with a large amount of gas,
In a large balloon, a lot of labor and time are required for a gas filling operation to secure a desired lift, and a lift adjustment matching the wind speed of the day is required.

In addition, a single large balloon requires a large facility for safely mooring the balloon in a strong wind, and there is also a problem in the treatment of gas when the large balloon is moved to another place. In particular, since helium gas is expensive, there is a problem in terms of cost if helium gas is released into the air during lift adjustment and movement. Therefore, there is a problem that a large-scale recovery device for recovering helium gas is required. In particular, a system that does not need to be extracted at the time of movement once it is filled with helium gas is ideal.

Further, if the balloon is damaged for any reason during the operation of filling the balloon with gas or during the flight in the air, the gas escapes or a sudden decrease in buoyancy due to the gas escape occurs, resulting in a safety problem. But there is a problem.

Accordingly, the present invention solves such various problems that exist in the conventional balloon, and can easily secure the lift of the balloon and adjust the lift in accordance with the wind speed. It is an object of the present invention to provide a collective balloon which has improved performance and is excellent in cost, operability and safety.

[0037]

As described above in detail, according to the collective balloon according to the present invention, if a net-like material such as a balloon net having a predetermined capacity is prepared, the number of small balloons can be reduced as a measure against wind, for example. By increasing or decreasing, it is possible to secure a lift that is not inferior to the wind speed, and it is possible to perform a lift adjustment that matches the wind speed. At this time, there is an effect that a large amount of labor and time are not required for determining the size of the balloon and filling the gas with gas to secure a desired lift unlike a conventional large balloon. That is, by increasing or decreasing the number of small balloons, the buoyancy can be arbitrarily adjusted without taking in and out of helium gas.

Since the collective balloon according to the present invention mainly handles a large number of small balloon units, a large facility for safely mooring in a strong wind is unnecessary, and it is sufficient to secure a place for storing the small balloon. Further, once the small balloon is filled with helium gas, the small balloon is moved for each small balloon at the time of movement, so that the gas does not need to be extracted, and a large-scale recovery device for recovering the helium gas is not required. In addition, gas filling and extracting operations to small balloons can be performed by up to two workers, and storage and removal of small balloons in the balloon net and movement to another location can be performed by one worker alone. It is.

Even when the collective balloon is moved to another place, it is not necessary to disperse expensive helium gas into the air, and the small balloon can be easily moved by using a container-like moving vehicle. Also, even if the balloon is damaged for any reason during the flight in the air, the damage is part of the small balloon, so there is no danger of a sudden decrease in buoyancy and there is no risk in terms of safety. Be perfect.

At the time of transporting materials using the collective balloon, the first and second winches and the guiding ropes derived from the respective winches are connected to the balloon directly and via pulleys, and the guiding ropes are sent out by the respective winches. By repeating the winding operation, the material in the vicinity of the line connecting the winch and the pulley can be suspended from the collection balloon and transported to the collection point, and the range in which the material can be lifted by moving the pulley to another position Can be changed and expanded.

The field of application of the collective balloon according to the present invention includes a material transport system in the event of a disaster, an emergency evacuation system in the event of a disaster, a civil engineering construction work system, a lumber export system, an aerial photographing and observation system, an agricultural work and transport system, a dam, etc. It can be used for cleaning systems, entertainment and sightseeing systems, cargo handling systems for harbors, video broadcasting systems from above, such as sports, temporary relay stations in the sky, and other applications.

Therefore, according to the collective balloon according to the present invention,
It is easy to secure the lift of the balloon and adjust the lift, improve the mooring and mobility of the balloon, and have excellent cost and operability.
It can be used in many fields by effectively utilizing the pollution-free and energy-saving properties of balloons.
