In order to lower and stabilize the center of gravity, a configuration provided at a low position is preferable. In particular, it is preferable that the inner room has a doorway through which the outside of the levitation device X can be entered and exited at the center in the horizontal direction on one surface of the frame body 11 . By aligning the directions of the main body parts 1 with such a structure, when connecting a plurality of main body parts 1, the positions of the entrances and exits of the inner rooms are also aligned, and the inner rooms can be easily moved.

The frame 11 has a piping portion 113 for passing wires connecting devices mounted inside (details will be described later) to the rotor blades 2 . The piping part 113 is a tubular member having a circular or rectangular cross section for storing electrical wiring and wired communication wiring, and is fixed to and supported by the frame 11 .

As shown in FIG. 1, the hatch 118 is a doorway provided near the lower side of the side surface of the main body 1, and has a structure that slides in the horizontal direction or a structure that can be opened and closed with a door that opens inward. Also, the hatch 118 is provided with a locking mechanism such as a hook or a bar at its edge (it is preferable that there are a plurality of locking mechanisms), and is configured to be fixable to the outer wall 111 . With such a configuration, unintentional opening of the hatch 118 during flight of the levitation device X can be prevented.

The frame 11 has scaffolding 119 on which the user can work inside the outer room. As shown in FIGS. 2 and 3, the scaffolding 119 is a path on a flat plate provided along the inner side of the outer wall 111 or bridging the outer wall 111 and the inner wall 112, and is 2 m in the height direction. It is provided so that it overlaps with an interval of about 3 m. With such a configuration, the user can perform the connection work at the connection portion 115 and the work such as maintenance of the wiring at the pipe portion 113 . Moreover, although not shown in the drawings, since the scaffolding 119 is used by people, it is preferable to provide a support in addition to the outer wall 111 and the inner wall 112 . Further, it is preferable to provide a locking portion such as a hook or a ring for locking a ladder for the user to climb onto the scaffolding 119 or for the user to attach a lifeline on the scaffolding 119 .

The air bag 12 is a bag-like component capable of enclosing a gas lighter than air, and has a sealing opening. For example, helium is enclosed in the air sac 12, and by covering the outer chamber of the main body 1 with it, the main body 1 alone obtains buoyancy. As shown in FIGS. 2 and 3 , the air sac 12 is inflated into a substantially rectangular parallelepiped shape with rounded corners, and is laid out in conformity with the shape of the main body 1 . The size of the air sac 12 is preferably 1 m in length, width, and height. may change.

However, depending on the size of the main body 1, six or more may be provided in order to distribute the load. In addition, the legs 13 are preferably detachable from the frame 11 so that the body 1 can be vertically stacked and connected.

The wheels 131 are positioned at the tips of the legs 13 and used as means of transportation when the levitation device X is transported on the ground. Also, the wheels 131 may be one per leg 13 like a helicopter, or two pairs (four) or three pairs (six) per leg 13 like an aircraft.

The buffer portion 132 is a portion that connects the frame 11 and the wheel 131 and provides a damping mechanism that absorbs shock and vibration applied to the wheel 131 . The damping mechanism is, for example, a configuration having pneumatic cylinders following the landing gear of an aircraft. With such a configuration, when the levitation device X lands, it is possible to reduce the risk of damaging the frame 11 or damaging parts other than the legs 13 due to vibration.

The body portion 1 has a solar cell 14 on its outer surface. The solar cell 14 is a panel or film solar power generation device provided outside the outer wall 111, and as shown in FIG. is preferred. With such a configuration, the power source for the rotor blades 2 can be obtained from the solar cells 14, and the flight time of the levitation device X can be lengthened. Moreover, it is possible to generate power by light striking the levitation device X from the side, and at the same time, more power can be generated.

The body portion 1 has a control portion 15 that controls the behavior of the levitation device X, particularly the rotor blades 2 . 2 and 3, the control unit 15 is a computer provided inside the frame 11, particularly in the inner room, and as shown in FIG. It has a sensor 153 , a transmitter 154 , a receiver 155 , a storage 156 , a thermometer 157 , a pressure gauge 158 and a calculator 159 .

“Control” of the rotor blades 2 in the present embodiment represents the number of rotations (rpm) of the rotor blades 2 or the rotation angle of a joint portion 222 to be described later.

Each unit of the control unit 15 can include hardware including a circuit in a broad sense, and software information processing realized through this hardware. Also used for communication is a network path, which may include the Internet protocol. Moreover, the type of communication protocol is not particularly limited, and the type and scale of the network are also not limited.

The position information sensor 151 is a position information system, so-called GPS, which recognizes the current position of the levitation device X in terms of latitude and longitude from information from satellites, and determines the flight route of the levitation device X based on this information. .

The gyro sensor 152 detects the attitude of the levitation device X in the air, particularly the rotational motion. Attitude control of the levitation device X is performed based on information acquired by the gyro sensor 152 .

The light intensity sensor 153 is a sensor that detects the amount of light received by the levitation device X in terms of brightness or energy amount, and determines the direction of the light source of the sunlight based on this information.

The transmission unit 154 is a communication device that transmits information obtained by the position information sensor 151, the gyro sensor 152, and the light intensity sensor 153 to the user on the ground using radio signals.

The receiver 155 is a communication device that receives a signal sent from a user on the ground. Moreover, it is preferable to have a configuration provided on a base integrated with the transmission unit 154 . By controlling the rotor blades 2 based on the information received here, the levitation device X can stably fly and generate power.

The storage unit 156 is a volatile memory that stores information received by the reception unit 155 and information acquired by the position information sensor 151 . As a result, the flight path of the levitation device X and the signals used for control can be stored as records. This record is sent from the transmitting unit 154 to the user on the ground, or is recovered when the levitation device X lands. preferably replaced. As a result, the amount of memory installed in the levitation device X can be minimized, and the tight capacity of the control unit 15 and the associated heat generation can be suppressed.

The thermometer 157 is a temperature sensor that measures the air temperature outside the levitation device X. As a result, the altitude and the rate of ascent of the levitation device X can be calculated by utilizing the fact that the temperature of the atmosphere decreases as the altitude increases. Moreover, a configuration in which a temperature sensor for measuring the temperature of the air sac 12 is provided is preferable.

It is preferable that the control unit 15 is provided with a heating device for adjusting the temperature of the bladder 12 together with the thermometer 157 . This heating device is a device that keeps the gas enclosed in the air bag 12 constant regardless of the altitude or heats it to a temperature higher than the air temperature outside the levitation device X, and uses power obtained from the solar cell 14. configuration is preferred. With such a configuration, sufficient buoyancy by the air bladder 12 can be ensured, and the electric power used to drive the rotor blades 2 can be reduced.

The pressure gauge 158 is a pressure sensor that measures the pressure outside the levitation device X. As a result, the altitude and the rate of ascent of the levitation device X can be calculated by utilizing the fact that the pressure of the atmosphere decreases as the altitude increases.

The calculation unit 159 is a so-called processor that processes information acquired by each unit of the control unit 15, causes the transmission unit 154 to transmit, stores it in the storage unit 156, and issues commands to control the rotor blades 2. . The calculation unit 159 performs position information processing, body information processing, and control processing. These will be described in detail below.

The position information processing is a process of linking the position information acquired by the position information sensor 151 with the position information accumulated in the storage unit 156 to update the data of the flight path, and the process of updating the data of the flight path, and the process of acquiring by the thermometer 157 and the pressure gauge 158. processing for calculating the altitude of the levitation device X based on the information on the temperature and pressure of the outside air, and processing for causing the transmission unit 154 to transmit position information and altitude information. As a result, the user can track the position of the levitation device X substantially in real time, avoid the route of the aircraft, and avoid collisions with other flying objects.

The aircraft information processing determines the direction of the sunlight and the angle formed by the sunlight and the solar cell 14 from the information acquired by the light intensity sensor 153, and combines it with the attitude and rotational motion of the levitation device X acquired by the gyro sensor 152. This is a process for causing the transmitting unit 154 to transmit.

In the control process, a control signal sent from the user on the ground and acquired by the receiving unit 155 is transmitted to the rotor 2 to vary the magnitude of the lift force, etc., and the levitation device X is moved to the target altitude, attitude, and direction. This is the process of moving. Further, a process of storing the control signal at this time in the storage unit 156 may be included.

In the aircraft information processing, the control signal generated by the user on the ground may not be used, but the processing of generating the control signal may be performed by the calculation unit 159, and the control signal may be used to perform the control processing. Thereby, the behavior of the levitation device X can be automated. In this case, the calculation unit 159 causes the transmission unit 154 to transmit the generated control signal so that the user on the ground can always grasp the state of the control. In an emergency, the receiver 155 receives a control signal from a user on the ground and prioritizes it for control processing.

The main body 1 has a storage battery 16 that stores power generated by the solar battery 14 . The storage battery 16 is a secondary battery such as a lithium-ion battery or a nickel-metal hydride battery, and stores the power generated by the solar battery 14 that is not used to drive the rotor blades 2 and the controller 15 . Moreover, it is preferable that the storage battery 16 has a structure that can be easily removed, or a structure that has a power recovery terminal such as an outlet. With such a configuration, the stored electric power can be easily recovered on the ground.

The storage battery 16 is provided with a charge amount detection unit 161 . The charged amount detection unit 161 detects the ratio of the charged amount to the capacity of the storage battery 16 . The detected power storage rate is read by the calculation unit 159 all the time or at regular time intervals, and is transmitted by the transmission unit 154 . In particular, when the charging ratio reaches 100% (or 90% or the like may be set as appropriate), the calculation unit 159 preferably causes the transmission unit 154 to transmit a charging completion signal.

The main body 1 has an environment maintenance device 17 that regulates the temperature and pressure inside the inner room. The environment maintenance device 17 is an air conditioner that maintains the temperature and pressure of the inner room at ground surface conditions, for example, 25° C. and 1013 hPa, even while the levitation device X is in flight. It also has the function of keeping the oxygen concentration in the inner room at the same level as the ground surface by the oxygen supply means. With such a configuration, plants (agricultural crops, flowers, etc.) can be cultivated in the inner room, and economic activities can be carried out comfortably with people on board.

The main body 1 has display means 18 on the bottom surface of the frame 11 and at least one side surface. The display unit 18 has a shape substantially the same as the bottom surface or the side surface of the frame 11, and is a screen capable of displaying images and moving images. With such a configuration, it is possible to display information such as advertisements, and also to display a warning to nearby aircraft or the like that they are approaching. Moreover, it is preferable that the display means 18 is configured to be as thin as possible. With such a configuration, it is possible to reduce the weight of the main body 1, and to secure a large space for mounting the bladder 12, thereby obtaining greater buoyancy.

When the main body 1 has the display means 18 on the bottom surface of the frame 11, it is preferable to have a configuration in which an image can be displayed on the entire bottom surface without providing the legs 13 as shown in FIG. With such a configuration, when the levitation device X is made to fly by connecting a plurality of main bodies 1 to each other, the bottom portion can be used as a large screen by combining a plurality of display means 18 . For example, as shown in FIG. 7, when connecting nine main bodies 1, the display means 18 is also used as a large screen in which nine screens are arranged. For this reason, it is preferable that the display contents of each display means 18 can be collectively controlled by one control unit 15 .

The main body 1 has a lightning protection device 19 . The lightning arrester 19 includes a metal member (for example, copper) having a small electric resistance provided on a part of the outer wall 111, and a discharge cable 191 (aircraft static discharge cable) connected to the metal member and extending downward from the bottom surface of the frame 11. similar to the charger). With such a configuration, it is possible to reduce the probability of damage to the levitation device X due to a lightning strike, based on the same principle as in aircraft.

The rotor blade 2 is a device that is connected to the main body portion 1 and generates lift, and has a blade main body 21 and a base portion 22 .

The wing main body 21 is a propeller that generates lift for lifting the levitation device X. As shown in FIG. Although the drawing shows two blades, it may be composed of three or more blades depending on the size. Also, the diameter of the blade main body 21 is set to be 3 m or more and 20 m or less, preferably 4 m or more and 15 m or less, according to the size of the main body portion 1 .

The base portion 22 is a columnar member to which the wing main body 21 is rotatably attached and connected to the main body portion 1. A power portion 221, a joint portion 222, and a main body connection portion 223 are provided. Further, the base portion 22 extends in a direction away from the main body portion 1 and is provided so that the wing main body 21 protrudes further outward than the main body portion 1 in the horizontal direction.

The power unit 221 is a motor that converts electric power generated by the solar cell 14 into power for rotating the wing body 21 . In addition, two power units 221 rotate in opposite directions so that the levitation device X does not rotate. For example, in the four rotor blades 2 shown in FIG. 1, two rotor blades on the diagonal rotate in the same direction, and two adjacent rotor blades rotate in opposite directions along the upper surface of the frame 11. provided to move.

The joint portion 222 is a shaft joint that allows the angle between the base portion 22 and the main body portion 1 to be changed by rotation. Alternatively, it may be provided integrally with the main body connection portion 223 to be described later. With such a configuration, the relative position and angle of the rotor blade 2, particularly the blade main body 21, with respect to the main body portion 1 can be changed as needed, and in a state in which a plurality of levitation devices X are connected as shown in FIG. , the interference between the blade bodies 21 can be prevented.

The joint part 222 preferably has a configuration in which rotation can be controlled by the control part 15 . This control is preferably a position control in which a target angle is determined from the attitude and distance of the main body 1 and adjusted to the target angle. With such a configuration, the position of the wing main body 21 can be appropriately changed according to the situation during flight.

The main body connection portion 223 is a columnar portion provided adjacent to or integral with the joint portion 222, penetrates into the rotor blade connection portion 114, and is easily fixedly connected by bolting or the like. In addition, terminals are provided for connecting the rotary blade connecting portion 114 to the electric circuit and communication circuit. have.

In the levitation of the levitation device X, as shown in FIG. 4, the lift of the wing body 21 and the buoyancy of the gas enclosed in the air sac 12 are combined. The levitation device X has a weight that enables levitation with the lift force of the wing body 21 added, not with the buoyancy of the gas alone. With such a configuration, the electric power used to drive the rotor blades 2 can be suppressed, and the levitation device X can be easily levitated and controlled.

In addition to the above conditions, the weight of the levitation device X is preferably limited to the extent that it can levitate even if the lift force by the wing body 21 is below a certain level. This means that the upper limit of the weight of the levitation device X is determined, for example, based on the value when the magnitude of the lift force is 50% of the magnitude of the buoyancy force. However, other criteria may be used in the method of determining this upper weight limit. With such a configuration, even if the rotor blade 2 or the power generator fails in the air and the levitation device X loses its lift, the buoyancy allows a gentle descent.

The main body 1, particularly the frame 11, is made of a lightweight material such as carbon fiber. As a result, the weight of the levitation device X can be reduced, and levitation can be achieved with less electric power. However, it is conceivable that the inner wall 112, the shutter 116, and other parts that need to withstand a large pressure difference may be constructed of other materials, such as metal.

A user who operates the levitation device X uses a controller capable of communicating with the control unit 15 . This controller only needs to be able to operate the rotor blades 2 and control the flight speed and attitude of the levitation device X, and is a known wireless controller used for controlling drones, for example. However, in order to communicate with the levitation device X that floats at a high altitude, it is preferable to use radio wave communication.

The levitation device X may have the following configuration. However, the configuration shown below is merely an example, and the presence or absence of each configuration can be independently determined unless otherwise specified.

≪Change example≫
The frame 11 may be provided with a wire that vertically connects the plurality of scaffolds 119 or the scaffolds 119 and the outer wall 111 or the inner wall 112 in the outer room. This wire positions the air sac 12 in the outer chamber so that it does not move. Such a configuration makes it easier to stack the air bags 12 vertically, and prevents the air bags 12 from shifting and changing the overall balance even if the levitation device X is tilted in the air.

When a plurality of levitation devices X are connected and made to fly, the control by the control unit 15 is performed at one place, and the rotor blades 2 and the environment maintenance device 17 are collectively controlled at the one place. Alternatively, the control units 15 provided in each main unit 1 communicate with each other to cooperate.

After that, the user repeats transmission and reception of each piece of information with the levitation device X, and lowers the levitation device X to the ground while maintaining its attitude.

It is assumed that the levitation device X will be lowered to the ground when the sun sets and solar power generation is not possible, when the storage battery 16 is fully charged, or just before supplies and resources for people to stay in the inner room run out. be done.

The altitude at which the floating device X floats is preferably 2000 m or more, preferably 3000 m or more. This makes it possible to avoid low-level clouds and efficiently generate solar power. In addition, since air currents in the sky are more stable than near the surface, wind power generation can be stably performed.

When the display means 18 is provided on the bottom surface of the main body 1 and the levitation device X flies by connecting a plurality of main bodies 1 together, the plurality of display means 18 are arranged and images and videos can be projected on the bottom as a large screen. can. This makes it possible to provide movies, sports broadcasts, and the like without using ground structures.
