Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] After the existing release, the change in the center of gravity caused by the projectile causes the drone to increase its rotation power, which not only easily leads to a reduction in endurance, but also a risk of crashing. In order to solve the above problems, this case proposes the following technical solutions:

[0036] See also Figures 1 to 7 The present invention provides a technical solution for a bomb-throwing high-rise building fire-fighting drone: its structure includes: a body 2, and a blade 4 installed on a support arm of the body 2, a camera 3 is provided at the front end of the body 2, a bottom frame 5 is extended downward from the bottom of the camera 3 to support the camera 3, and a movable bomb thrower 1 is provided between the bottom frames 5, characterized in that: the bomb thrower 1 includes a locking top frame 11 fixed to the bottom of the body 2, a mutually nested barrel 13 is provided at the bottom of the locking top frame 11, and a driver 12 is provided between the locking top frame 11 and the barrel 13;

[0037] The barrel 13 includes a bottom barrel 131, a top barrel 132, and a guide sleeve 135. The bottom barrel 131 and the top barrel 132 form a cavity. Both ends of the bottom barrel 131 and the top barrel 132 are nested with the guide sleeve 135. A movable groove 134 is fixed on the top of the top barrel 132. The top barrel 132 is nested with the locking top frame 11 through the barrel 13. A first slide rail 133 is arranged inside the top barrel 132.

[0038] The bottom cylinder 131 includes a cylinder body 313, side plates 312 are provided on both sides of the cylinder body 313, the cylinder body 313 cooperates with the top cylinder 132 through the side plates 312, and limiters 311 are provided between the side plates 312 and the top cylinder 132, and the limiters 311 are distributed on both sides of the cylinder body 313. A raised second slide rail 314 is provided on the surface of the first slide rail 133, and a reducer 315 is provided in the middle through groove of the second slide rail 314. The second slide rail 314 and the first slide rail 133 inside the top cylinder 132 form a slideway.

[0039] The main structure of the device includes a flying device formed by a body 2 and blades 4. The on-site position is monitored through a front-end camera 3, and high-rise buildings can be monitored. The specific camera 3 can be an infrared camera, which can also obtain a field of view at night, and is more convenient to use.

[0040] In order to prevent the bomb launcher 1 at the bottom from rubbing against the ground during daily use, a bottom frame 5 provided at the bottom of the body 2 is provided for support.

[0041] The bomb launcher 1 is fixed to the bottom of the body 2 by locking the top frame 11. The bottom of the locking top frame 11 controls the swing of the barrel 13 through the driver 12. The barrel 13 is used to load the fire extinguishing ball. When the fire extinguishing ball encounters an open flame, the fire extinguishing fuse wound on the surface is burned, and then the inner core explosion device is driven to automatically spray dry powder to achieve the effect of automatic fire extinguishing.

[0042] The barrel 13 is provided with a bottom barrel 131 and a top barrel 132, which are nested and limited by a guide sleeve 135 at the front and back. The nesting of the guide sleeve 135 can facilitate alignment when loading the fire extinguishing ball, and can reduce resistance when the fire extinguishing ball falls out. At the same time, the symmetrical design on both sides can reduce the load caused by imbalance.

[0043] The bottom cylinder 131 is provided with side plates 312 on both sides of the cylinder 313, and the side plates 312 are provided with limiters 311. The limiters 311 are located on both sides of the cylinder 313 to control the movement of the fire extinguishing ball and thus achieve a balancing effect. A second slide rail 314 is provided on the cylinder 313, and the second slide rail 314 forms a track with the first slide rail 133. The track fits the curvature of the fire extinguishing ball, thereby controlling the fire extinguishing ball to move in the slideway formed by the first slide rail 133 and the second slide rail 314. The sliding of the fire extinguishing ball can be restricted when the limit sleeve 115 raised by the limiter 311 is locked. At the same time, a local support is provided between the cylinder 313 and the second slide rail 314 to reduce friction and improve the smoothness of the movement of the fire extinguishing ball.

[0044] However, the fire extinguishing ball may shake when flying too smoothly, so a speed reducer 315 is provided in the middle groove of the second slide rail 314 to slow down the moving speed of the fire extinguishing ball during storage.

[0045] The specific structure of the reducer 315 includes a bottom plate 151, and a positioning plate 152 wrapped around the bottom of the cylinder 313, so that the positioning plate 152 is embedded in the groove of the cylinder 313, and a first support wheel 153 is arranged between the positioning plates 152, and the belt body 154 is supported by the first support wheel 153, and a plurality of deceleration rollers 155 are arranged inside the belt body 154, and the deceleration roller 155 is connected to the reset shaft 156 inside the positioning plate 152, and springs are arranged above and below the connection between the reset shaft 156 and the deceleration roller 155, so that the deceleration roller 155 can be in a central position to support the belt body 154, and the belt body 154 can be attached to the surface of the fire extinguishing ball through the movable cooperation of the reset shaft 156. Since a plurality of deceleration rollers 155 are arranged, the belt body 154 rubs against it when rolling, thereby reducing the moving speed of the fire extinguishing ball.

[0046] The main structure of the cylinder 313 is arranged on the motor 111 to drive the inner driving belt 113 installed on the driven wheel 112 and the main shaft roller of the motor 111 to move. The surface of the inner driving belt 113 is also covered with an outer driving belt 114. The surface of the outer driving belt 114 is provided with a groove to be nested with the limit sleeve 115, and the limit sleeve 115 is provided with an inner cavity, and a pulley frame 117 is arranged in the cavity. When the outer driving belt 114 pushes the limit sleeve 115 to contact with the ball, the limit sleeve 115 will generate a shape The ball contacts the internal pulley frame 117, and when the fire extinguishing ball rolls, the pulley frame 117 will roll adaptively, thereby causing surface wear of the limiting sleeve 115 due to rotational friction in the morning, and in order to enable the opening of the limiting sleeve 115 to be quickly sunken during the contact process, a slide groove 116 is provided at the opening of the limiting sleeve 115, and the slide groove 116 is located on both sides of the wheel body of the pulley frame 117, which can avoid blockage of the wheel body when embedded, and is smoother when rolling.

[0047] In addition, a movable groove 134 is provided at the top of the top cylinder 132 to connect with the main shaft of the driver 12. The driver 12 can drive the barrel 13 to coordinate the pitch angle. When the fire extinguishing bomb inside the barrel 13 pops out, the internal balance will change. The adjustment of the rotation angle of the barrel 13 by the driver 12 can make the fire extinguishing ball located at the center position, thereby balancing the center of gravity. At the same time, the limiters 311 are set one on the left and the other on the right to control the opening and closing of the channels on both sides of the fire extinguishing ball. When the motor 111 controls the inner drive belt 113 When the outer driving belt 114 moves and the limiting sleeve 115 moves toward the middle, the fire extinguishing ball can be clamped. After clamping, the fire extinguishing ball is in the center position, so that the center of gravity of the aircraft can be quickly adjusted. When it is necessary to drop a bomb, the deceleration roller 155 moves to one side. When the limiting sleeve 115 at the end moves into the cavity of the guide sleeve 135, the fire extinguishing ball will be quickly separated because the diameter of the guide sleeve 135 is the same as the diameter of the cylinder 313 composed of the top cylinder 132 and the bottom cylinder 131. Then the limiting sleeve 115 is quickly reset to reset and adjust, and the fire extinguishing ball is gathered in the middle again.

[0048] The improved device decelerates the fire extinguishing ball through the reducer 315, and then the limiter 311 controls the center of gravity of the fire extinguishing ball. The reduced fire extinguishing ball can be quickly adjusted to the center after each use by clamping and pushing. The diameters of the guide sleeve 135 and the cylinder 313 formed by the bottom cylinder 131 and the top cylinder 132 are inconsistent, which can enable the fire extinguishing ball to be quickly separated from the limiter 311 during separation, thereby increasing the speed of resetting the limiter 311 and facilitating the position adjustment when loading the fire extinguishing ball. Specifically, when loading the fire extinguishing ball, the outer driving belt 114 on one side drives the limiter sleeve 115 to move to the inside of the guide sleeve 135, and the fire extinguishing ball is inserted between the first slide rail 133 and the second slide rail 314, and is decelerated by the reducer 315 to prevent the fire extinguishing ball from freely moving and falling off during loading.

[0049] The above only describes the basic principles and preferred implementations of the present invention. Those skilled in the art may make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of the present invention.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
