As shown, the aerial camera flight unit according to the present invention consists of a projectile 10, a maneuver 20 and a vehicle 30.

The projectile 10 forms a receiving space 11 in a longitudinal direction from a lower end thereof, and a pair of through-holes 12 formed at a point spaced apart from a central axis at an upper end thereof, as shown in FIG. 3. Thrust generating means 13 is provided to protrude so as to interfere with the straight copper wire connecting the balls 12.

The thrust generating means 13 may be configured in a variety of forms, in the present embodiment is made of a ring shape, the outer periphery is formed a screw thread that can be engaged with the rack gear 21 of the starter 20 The inner periphery is configured to have a screw thread that is engaged with the thrust transmission gear 31 formed at the lower end of the vehicle 30.

At this time, the thrust generating means 13 has a transverse power transmission structure for transmitting the rotational force transmitted to the outer circumference through the inner circumference, the top and bottom are rotatably installed on the projectile (10). That is, the upper and lower ends of the thrust generating means 13 is provided with a protruding sliding protrusion 14 and the projecting body 10 is inserted into the sliding protrusion 14 to guide the movement of the protrusion (15) This can be arranged.

In addition, a cradle 16 on which the propeller 33 can be mounted is provided at an upper end of the projectile 10 so as to correspond to the number of the propellers 33.

The starting unit 20 is accommodated in the storage space 11 of the projectile 10 when not in use, and is inserted into the through hole 12 when in use, and the thrust generating means 13 by pulling the handle 23. To drive. At this time, the rack gear 21 is formed at one end of the starting portion 20 is made of a structure that can be engaged with the screw thread formed on the outer periphery of the thrust generating means (13).

On the other hand, the vehicle 30 is raised as the first thrust by the thrust generated by the thrust transmission gear 31 is installed in the thrust generating means 13 of the projectile 10 is raised, and the generated thrust is transmitted to the inside. The electric motor 32 is driven by the battery 42, so that the propeller 33 rotates so as to be secondaryly raised. In other words, the thrust transmission gear 31 formed at the lower end of the vehicle is engaged with the thrust generating means 13 of the projectile 10 to receive the driving force of the thrust generating means 13 by the maneuver 20. When rotating the propeller 33 installed on the top of the vehicle while rotating, the control unit 36 drives the electric motor 32 by the rotation of the propeller 33 as a signal.

In addition, the camera 35 is mounted on the lower end of the vehicle 30 toward the lower end. The camera 35 is mounted in a state where a bearing is placed on a vehicle, so that the camera is not rotated even when the vehicle rotates.

And the propeller 33, as shown in Figure 1, is made of a foldable structure that can be folded down for convenience of portability. In addition, the propeller 33 is provided with one or more light sources 34 for emitting light to the lower end. At this time, since the light emitted from the light source 34 is to form the photo zone PZ on the ground, it is preferable that the laser is excellent in the straightness of the light.

In addition, in this embodiment, the light source 34 is illustrated as being mounted at the stop of each propeller 33, but the position and the number of the light sources 34 are not limited thereto.

In addition, the control unit 36 provided in the air vehicle 30 includes an altitude sensor (not shown) capable of detecting an altitude, an inclination sensor (not shown) detecting an inclination of the air vehicle 30, and the altitude sensor. The vehicle 30 is controlled by the altitude value detected by the tilt angle detected by the tilt sensor. This stops the driving of the electric motor 32 when there is a fear that the air vehicle 30 is lost due to the wind or gusts to lose balance, and to prevent human injury by driving the propeller 33, This is to protect the air vehicle 30 by allowing the parachute 37 installed on the air vehicle 30 to be unfolded.

As shown in FIG. 6, the parachute 37 is inserted into an accommodating part 38 provided at an upper end of the vehicle 30 and covered with a cover 39. And the spring 41 is connected to the plate 40 in which the parachute 37 is installed. Therefore, when the cover 39 is inserted into the housing 38, the cover 39 presses the plate 40, causing the spring 41 to contract, thereby increasing the restoring force, and in this state, the cover 39 is stored in the housing 39. It is fitted into the stopper (not shown) of 38 and fixed. At this time, the stopper has a structure capable of reversing by hitting or driving a separate motor to allow the spring 41 to generate a restoring force.

Next, the operation of the aerial camera flight unit according to the present invention will be described.

When carrying the aerial camera flight unit according to the present invention, as shown in Figure 1, insert the maneuver 20 into the storage space 11 of the projectile 10, and folded the propeller 33 to the bottom volume Can be minimized.

When the camera 35 needs to be photographed, first, the starter 20 is dismantled from the storage space 11 of the projectile 10 and inserted into the pair of through holes 12 formed in the projectile 10.

In addition, the folded propeller 33 is placed on the cradle 16 of the projectile 10. At this time, the cradle 16 is provided so that the propeller 33 can be supported in a bent state of about 5 ° so that the cradle 16 does not cause interference when the propeller 33 is driven.

Subsequently, when the puller 20 inserted into the through hole 12 is pulled, the rack gear 21 provided at one end of the puller 20 is engaged with the outer circumference of the thrust generating means 13 while the thrust generating means ( 13) Rotate At this time, the rotational force of the thrust generating means 13 is transmitted to the thrust transmission gear 31 of the vehicle 30 so that the propeller 33 is rotated. When the propeller 33 is rotated, the controller 36 drives the electric motor 32 so that the propeller 33 continuously rotates to generate thrust.

As described above, in the present invention, the propeller 33 rotates first by the rotational force transmitted by the thrust transmission gear 31, and the propeller 33 rotates secondly by the electric motor 32. This consumes a lot of energy to generate a lift force only to the electric motor 32, but to minimize the energy consumption by the electric motor 32 because it generates a primary lift force by the external force by pulling the starter 20. For sake.

When the vehicle 30 rises, the photo zone PZ is formed on the ground by the light emitted from the light source 34 of the propeller 33. At this time, when a person enters into the photo zone PZ, the camera 35 recognizes the object and photographs the object continuously at set time intervals. That is, in the present invention, the camera 35 does not take a picture while checking about an image to be captured, but takes a method of acquiring a more complete image by taking pictures at various viewpoints in the photo zone PZ.

And since the aircraft 30 is provided with an altitude sensor, the control unit 36 controls the rotational speed of the electric motor 32 based on the altitude value detected by the altitude sensor so that the aircraft 30 stays at the altitude set by the user. can do.

In addition, if the air vehicle 30 is out of balance due to strong winds or gusts of wind blown by the air vehicle 30, the air vehicle 30 may fall abnormally and fall, causing damage to or damage to the air vehicle 30. Therefore, in the present invention, by detecting the sudden rise or fall or tilt of the aircraft 30 through the altitude sensor and the tilt sensor to stop the driving of the electric motor (32).

At this time, when the electric motor 32 is stopped, the air vehicle 30 falls freely and falls to the ground, which may cause damage to the air vehicle 30. In order to prevent this, in the present invention, when the above situation occurs or lands the aircraft 30, the aircraft 30 can slowly descend through the parachute 37.

As shown in FIG. 6, the parachute 37 is shown in FIG. 7 while the cover 39 is separated by the restoring force of the spring 41 as the stopper retreats while the cover 39 is fixed by the stopper. As shown, it is released to the top and straightened out.

Since the parachute 37 is mounted on the plate 40, the parachute 37 may be stored and reused as shown in FIG. 6 after landing of the vehicle 30.
