Description

{A performance drone equipped with a device for generating and maintaining a large amount of bubbles}

The present invention relates to a performance drone equipped with a device for generating and maintaining a large amount of bubbles. More specifically, the downward wind generated from the propeller of the drone is guided to the bubble generator through an air induction tray to generate a large amount of bubbles continuously or The large amount of bubbles generated while repeatedly being generated are safely protected by an air blocking cover to prevent them from being destroyed by the downward wind of the propeller or surrounding air currents, and can be stably dispersed in the air, thereby preventing haze, laser beams, LED beams, and large amounts of bubbles. This relates to a performance drone equipped with a large amount of bubble generation and maintenance device that can maximize performance special effects in mixed use drone performances.

An unmanned aerial vehicle or drone (hereinafter collectively referred to as a drone) is an unmanned aircraft that can be controlled by radio waves, and is equipped with cameras, sensors, communication systems, etc., and is equipped with electronic communication technology. As development progresses, it is being expanded into various fields such as military use, agricultural use, leisure use, and performance use.

In particular, when drones are used for performances, the performance is performed by emitting laser beams or LED beams and scattering special effect materials such as bubbles or fog to generate diffuse reflection of light. In the case of such drone performances, ground control is required. The lighting device of the center or drone emits an LED beam or laser beam through a beam projector, and at the same time, a separate bubble generator or mist generator generates bubbles or mist and scatters them in the sky, thereby generating the laser beam or LED beam on the light path in the air. As light particles are scattered by bubbles or fog, diffuse reflection of light occurs, improving the visual effect of the performance.

However, in the case of drone performances using special effect materials such as bubbles or fog, they are performed at an altitude above a certain height, so if bubbles are generated and released from a flying drone, there is a limit to the load the drone can withstand or the battery Due to limitations in usage time, there are many limitations to blindly generating a large amount of bubbles.

Additionally, when bubbles are generated from a bubble generator installed in a ground control center and fired into the sky, the bubbles generated by the bubble generator may be scattered in an undesirable direction by the wind generated from the drone's propeller or fail to rise to the desired height and fall due to gravity. Because it easily sinks to the ground, there were many limitations in creating special effects using a large amount of bubbles.

In this regard, Republic of Korea Patent Publication No. 10-2022-0089773 (published on June 29, 2022; hereinafter abbreviated as 'Patent Document 1') is a known technology developed and applied for by the present applicant, in which the air from the upper part is transferred to the lower part. A bubble generating device using a drone is described that can continuously or repeatedly create large bubbles or large bubbles using a drone propellant that pushes out and generates flotation and/or thrust.

However, in Patent Document 1 above, bubbles are generated by the propeller wind of the drone and continuous belt running or repetitive folding operation, so bubbles are also generated by the propeller wind of the drone in flight, but on the other hand, the already created bubbles are generated by the propeller wind. There were many limitations in maximizing the performance effect or special effects caused by the large amount of bubbles.

Therefore, there is a need for the technology of a large-capacity bubble generating device that can generate a large amount of bubbles and maximize the performance effect by safely and effectively spreading them into the air or reaching the desired location without crushing the already-generated bubbles. .

According to the present invention, the wind and surrounding air of the propeller, which is a propellant that pushes the upper air downward to generate buoyancy and/or propulsion, is guided to the aberration-type bubble generator by an air induction tray to generate a large amount of bubbles continuously or repeatedly. The large amount of bubbles generated at the same time are safely protected and released by an air blocking cover to prevent them from being easily destroyed by the wind of the propeller (propellant) or surrounding air currents, so that a large amount of bubbles are stably maintained in the air above for a relatively long period of time. By allowing it to spread, it provides the advantage of stably combining a large amount of bubbles with fog, laser beams, or LED beams in drone performances to effectively maintain and maximize the special effects of the performance for a long time.

In addition, in the performance drone equipped with the device for generating and maintaining a large amount of bubbles of the present invention, the propeller 11 pushes the air from the upper part of the rotor toward the lower part of the rotor through rotation of the rotor to form a descending airflow, thereby providing the lift force and/or necessary for drone flight. Or, as one that generates thrust, it may be one of a bicopter (2 rotors), a quadcopter (4 rotors), a hexacopter (6 rotors), or an octocopter (8 rotors).

In addition, in the performance drone equipped with the device for generating and maintaining a large amount of bubbles of the present invention, the landing gear 12 includes a plurality of vertical supports 12a installed vertically at the lower part of the drone body 10, as illustrated in FIG. 1. It may be composed of a plurality of horizontal supports (12b) that connect and support a pair of adjacent vertical supports (12a).

As illustrated in FIG. 1, the water wheel support plate 20 is installed horizontally by the vertical support 12a of the landing gear 12, and the water wheel type bubble generator 30 is mounted on the lower part of the drone body 10. and creates a space for operation.

The water wheel-type bubble generator 30 is installed on the water wheel support plate 20, and includes a water wheel repeatedly and continuously submerged or floating in the bubble liquid by the power of the motor, and the wind of the propeller 11 ( A large amount of bubbles are continuously or repeatedly generated and stably released using the downward wind or downward air current) and the inflow of surrounding air. To this end, the water wheel-type bubble generator 30 includes a bubble liquid cartridge 31, a water wheel for bubble generation 32, an air induction tray 33, and an air blocking cover 34, as illustrated in FIG. 3. It can be configured, and side covers 35 forming the side cross-sectional shape of the aberration-type bubble generator 30 can be installed on both sides of the aberration-type bubble generator 30, as illustrated in FIG. 5. there is.

The bubble liquid cartridge 31 is installed on the water wheel support plate 20, and as illustrated in FIG. 3, a part of the body is removed in the longitudinal direction for storage of the bubble liquid 31d and internal installation and rotation of the water wheel. It is provided with a partially open cylindrical space (31a), and an air inlet (31b) through which the wind of the propeller (11) and surrounding air can flow is formed on one open side of the cylindrical space (31a), and the cylindrical space (31a) is provided. A bubble outlet 31c for releasing bubbles is formed on the other open side. At this time, the bubble outlet 31c is preferably formed to be lower in height than the air inlet 31b to facilitate the discharge of bubbles generated inside the cylindrical space 31a.

The bubble generating water wheel 32 is installed longitudinally in the cylindrical space 31a of the bubble liquid cartridge 31, and as illustrated in FIG. 4, a plurality of water wheel blades 32a are radially assembled, and the motor 32b It is installed to be able to rotate (rotate) inside the cylindrical space (31a) and is installed to rotate by the motor (32b) to repeatedly sink or float in the bubble liquid (31d) within the cylindrical space (31a). do. As a result, when the bubble generating water wheel 32 is submerged, a plurality of water turbine blades 32a contain bubble liquid, and when floating, a large amount of bubbles can be continuously or repeatedly generated by wind flowing in from the outside. This bubble generating water wheel 32 has a plurality of water turbine blades 32a horizontally aligned and commonly assembled on a motor connection shaft 32c rotated by a single motor 32b in order to repeatedly and continuously generate a large amount of bubbles. It is preferable that it is composed of a water wheel blade assembly.

The air induction tray 33 is a tray structure of L-shaped cross-section with a side wall on one side and an open other side, and is installed in front of the air inlet 31b of the bubble liquid cartridge 31 as illustrated in FIGS. 2 and 3. The open part of the L-shaped cross-section is installed to be connected to the air inlet (31b) of the bubble liquid cartridge 31, so that the wind (downwind or downward airflow) of the propeller 11 is transmitted through the tray structure of the L-shaped cross-section to the bubble liquid cartridge. It is configured to be guided to the air inlet (31b) of (31). In addition, a blower (33b) is formed on one side of the side wall of this L-shaped tray structure, and at the rear of the blower (33b) is a blower (33a) whose blowing speed or blowing flow rate is adjusted by the flight control module mounted in the drone body (10). Can be installed. By adjusting the speed or flow rate of the blower (33a) to control the amount of wind flowing into the air inlet (31b) of the bubble liquid cartridge (31), bubbles are generated in the water wheel blade (32a) of the bubble generating water wheel (32). It becomes possible to control the amount of production

When this blower (33a) is operated, the wind (downward wind or downward airflow) of the propeller (11) flowing into the tray of the L-shaped cross-section is mixed with the wind of the blower (33a) coming out through the tuyere (33b) to create a bubble liquid cartridge. It can be introduced together into the air inlet (31b) of (31). As a result, the air induction tray 33 continuously and stably guides the wind of the propeller 11 and the flow of surrounding air toward the air inlet 31b by the blower 33a and the tray structure with an L-shaped cross section, thereby creating the wind necessary for bubble generation. Not only can it be supplied sufficiently and efficiently to the bubble generating water wheel 32, but it is also possible to prevent the bubbles generated in the bubble generating water wheel 32 from flowing back toward the air inlet 31b. Therefore, the performance drone according to the present invention can fundamentally block the application of backflowed bubble liquid to GPS or communication equipment mounted on the drone body, thereby eliminating the possibility of communication failures in the aircraft.

The air blocking cover 34 is installed at a distance from the upper part of the bubble liquid cartridge 31 and is sized to cover the entire upper part of the bubble liquid cartridge 31 and the upper part of the bubble outlet (31c), thereby lowering the propeller 11. It blocks airflow (wind) from flowing into the upper part of the cylindrical space (31a) and the bubble outlet (31c) of the bubble liquid cartridge (31). As a result, the air blocking cover 34 allows a large amount of bubbles repeatedly and continuously generated by the bubble generating water wheel 32 to be stably released without being easily destroyed by the downward air current of the propeller or abnormal air currents around the drone. The bubbles required for the performance can be maintained and spread in the air above for a relatively long period of time.

In addition, the air blocking cover 34 may have a bent portion 34a formed at one end thereof, that is, the body at the end near the bubble outlet 31c bent at a certain angle downward along the longitudinal direction. This bent portion (34a) can block the wind from the propeller (11) from flowing back in from the side of the cylindrical space (31a) and the bubble outlet (31c) of the bubble liquid cartridge (31). As a result, the air blocking cover 34 allows a large amount of bubbles repeatedly and continuously generated by the bubble generating water wheel 32 to flow back from the side of the cylindrical space 31a and the bubble outlet 31c of the bubble liquid cartridge 31. It can be stably released without being destroyed by the downdraft of the propeller or abnormal air currents around it, and thus allows the bubbles needed for drone performances to efficiently maintain and spread in the bubble state for a relatively long period of time in the air above.

In addition, this air blocking cover 34 guides the rotational movement of the water turbine blade 32a of the bubble generating water wheel 32 inside, that is, located at the upper part of the cylindrical space 31a of the bubble liquid cartridge 31. A curved portion 34b may be formed. This curved portion 34b facilitates the rotation of the water turbine blade 32a of the bubble generation water wheel 32, so that a large amount of bubbles can be released relatively stably from the water turbine blade 32a of the bubble generation water wheel 32. Allows you to create .

The side covers 35 are installed on both sides of the water wheel-type bubble generating unit 30, and are provided with separate sealing means such as rubber packing or O-ring for airtightness and separate couplings such as bolts or bolt assembly grooves for assembly or separation. It is airtightly coupled and installed by means 35a, and is formed in the shape of the side cross-section of the aberration-type bubble generator 30, as illustrated in FIG. 5, and completely closes both cross-sections of the aberration-type bubble generator 30. .

The fogger 40 is installed on one side of the water wheel-type bubble generator 30, that is, on the air induction tray 33, and is installed in plural pieces at equal intervals in the longitudinal direction of the air induction tray 33, and is installed on the drone body (10). ) is controlled by the flight control module mounted within the machine to spray mist toward the air inlet (31b) of the aberration-type bubble generator (30). As a result, the mist generated in the mist machine 40 and introduced into the air inlet 31b can be captured and trapped inside the bubble when the bubble is created in the bubble generating water wheel 32, allowing it to travel a long distance in the future according to the movement of the bubble. Or, in the case of daytime, the shape of the bubble can be visually confirmed clearly, or various colors can be expressed depending on the color of the smoke screen or haze. When the bubble bursts, the haze trapped in the bubble spreads, creating a drone performance. By stably combining a large amount of bubbles, laser beams, LED beams, or flames, special effects can be derived continuously, stably, and effectively.

The beam irradiator 50 is installed on one side of the water wheel support plate 20, and is controlled by the flight control module mounted in the drone body 10 toward or below the bubble outlet 31c of the water wheel type bubble generator 30. By irradiating an LED beam or laser beam laterally, it is possible to stably combine a large amount of bubbles, mist, or flames in a drone performance to effectively derive performance special effects continuously and stably.

The flame irradiator 60 is installed on one side of the water wheel support plate 20, and is controlled by the flight control module mounted in the drone body 10 toward or below the bubble outlet 31c of the water wheel type bubble generator 30. By irradiating flames laterally, it is possible to stably combine a large amount of bubbles, mist, laser beams, or LED beams in a drone performance to effectively derive performance special effects continuously and stably.

The operation and effects of the performance drone equipped with the device for generating and maintaining a large amount of bubbles according to the present invention configured as described above will be described as follows.

First, the water wheel support plate 20 is mounted horizontally in the longitudinal direction of the drone body on the vertical support 12a of the landing gear 12, and the water wheel type bubble generator 30 is mounted and operated on the lower part of the drone body 10. A space for is formed, and a waterwheel-type bubble generator 30 is installed on the waterwheel support plate 20 in the longitudinal direction of the drone body.

At this time, the bubble liquid cartridge 31 of the water wheel-type bubble generator 30 removes a part of the body in the longitudinal direction to form an air inlet 31b on one open side of the cylindrical space 31a to generate wind from the propeller 11. and surrounding air can be introduced, and a bubble outlet (31c) is formed on the other open side of the cylindrical space (31a) to allow bubbles to be released.

Next, the bubble generating water wheel 32 is installed in the longitudinal direction inside the cylindrical space 31a of the bubble liquid cartridge 31, and the plurality of water wheel blades 32a are rotated (rotated) as one by one motor 32b. ) Commonly assembled on a single motor connection shaft (32c) as much as possible, and with both end surfaces of the aberration-type bubble generating unit (30) airtightly closed as a whole with the side cover (35), the bubble liquid is inside the cylindrical space (31a) (31d) is filled so that sinking or floating can be continuously repeated when the plurality of water blades (32a) of the bubble generating water wheel (32) are rotated as one unit by one motor.

Next, prepare an air induction tray (33) of L-shaped cross-section, which has a side wall on one side and is open on the other side, and install it in front of the air inlet (31b) of the bubble liquid cartridge (31), where the open part of the L-shaped cross-section is By connecting to the air inlet (31b) of the cartridge 31, the downward airflow of the propeller (11) can be easily diverted and guided to the air inlet (31b) of the bubble liquid cartridge (31) by the tray structure with an L-shaped cross section. make it possible

In addition, a blower (33a) is installed on the rear side of the blower (33b) formed on one side of the side wall of this L-shaped tray structure, and the air inlet of the bubble liquid cartridge (31) is adjusted by adjusting the speed or flow rate of the blower (33a) as necessary. By allowing the amount of wind flowing into (31b) to be adjusted, it is possible to control the amount of bubbles generated in the water wheel blade (32a) of the bubble generating water wheel (32).

Next, the air blocking cover 34 is installed spaced apart to the upper part of the bubble liquid cartridge 31 and the bubble outlet 31c side, thereby completely covering the upper part of the bubble liquid cartridge 31 and the upper part of the bubble outlet 31c, so that the propeller Prevent the descending airflow (wind) of (11) from flowing into the upper part of the cylindrical space (31a) and the bubble outlet (31c) of the bubble liquid cartridge (31).

After this assembly is completed, when the drone flight begins and a downward airflow of the propeller 11 occurs, the downward airflow of the propeller 11 is guided by the air induction tray 33 and the air inlet of the bubble liquid cartridge 31 ( 31b) is reached. At this time, when the blower (33a) is operated by the flight control module mounted in the drone body, the downward airflow of the propeller (11) flowing into the tray with an L-shaped cross section is combined with the wind of the blower (33a) coming out through the vent (33b). They are mixed and can be introduced together into the air inlet (31b) of the bubble liquid cartridge (31).

At this time, when the motor (32b) of the bubble generating water wheel (32) is rotated by the flight control module mounted in the drone body, the plurality of water turbine blades of the bubble generating water wheel (32) commonly assembled on one motor connecting shaft (32c) (32a) rotates at the same time, and this rotation causes the plurality of water turbine blades (32a) to continuously repeat sinking or floating, causing the bubbles that each water turbine blade (32a) contains when submerged. When floating, the liquid can continuously or repeatedly generate a large amount of bubbles due to the downward airflow of the propeller and the wind of the blower.

Meanwhile, on the air induction tray 33 side, the wind of the propeller 11 and the flow of surrounding air can be continuously and stably guided toward the air inlet 31b using the blower 33a and the tray structure with an L-shaped cross section. The wind required for bubble generation can be sufficiently and efficiently supplied to the bubble generation water wheel 32.

Afterwards, a large amount of bubbles generated from the bubble generating water wheel 32 are pushed toward the bubble outlet (31c) by the downward airflow of the propeller (11) and the wind of the blower (33a), and the bubbles that reach the bubble outlet (31c) are is safely protected from the downward air current of the propeller by the air blocking cover 34 and its bent portion 34a at the top, and is not destroyed by the downward air current of the propeller or surrounding abnormal air currents, but is stably maintained through the bubble outlet (31c). It can be released into the air, and the bubbles needed for drone performances can then be maintained and spread in the bubble state for a relatively long time in the air above.

In addition, at the upper part of the bubble generation water wheel 32, an air flow is formed from the air inlet 31b side to the bubble outlet 31c by the blower 33a and the tray with an L-shaped cross section, so that bubbles are generated in the water wheel 32. As the bubbles no longer flow back toward the air inlet (31b), it is possible to fundamentally block the application of the backflowed bubble liquid to GPS or communication equipment mounted on the drone body, thereby reducing the possibility of communication failures in the aircraft. It can be resolved.

According to the present invention, a large amount of bubbles are continuously or repeatedly generated using a propeller (propeller) that pushes the upper air downward to generate buoyancy and/or propulsion, and the large amount of bubbles generated are generated by the wind or surroundings of the propellant. By allowing it to spread into the air without being destroyed by air currents, etc., it provides the effect of maximizing the performance effect in drone performances where special effects are derived by combining bubbles with fog, laser beams, or LED beams. do.
