Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and specifically relates to a UAV-specific fire extinguishing bomb throwing device. Background Technology

[0002] The increasing payload and endurance of drones enable them to carry heavier and more fire extinguishing bombs for missions. Utilizing advanced navigation systems (such as GPS and gyroscope sensors), drones can quickly locate fire sources and accurately deploy fire extinguishing bombs under complex weather conditions. The modular design of the fire extinguishing bomb pods facilitates quick replacement of different bomb types; simultaneously, a stable fixing mechanism and a safe triggering device ensure that the fire extinguishing bombs will not loosen or fall off during flight and can be accurately released at the designated location. However, existing drone fire extinguishing bomb deployment devices mostly employ methods such as binding, hanging rings, and integral deployment pods. Binding and hanging ring deployments are inefficient and pose risks such as detachment or disengagement. Deployment pods also present the problem of multiple deployed items being individually uncontrollable. Therefore, existing drone fire extinguishing bomb deployment devices suffer from safety issues and low efficiency.

[0003] Therefore, in view of the problems of unsafety and low efficiency of existing drone-based fire extinguishing bomb throwing devices, there is a need to provide a drone-specific fire extinguishing bomb throwing device. Utility Model Content

[0032] Example 1:

[0033] A drone-specific fire extinguishing grenade throwing device includes a grenade launcher body 1 and a release device, wherein:

[0034] The aforementioned grenade launcher body 1 is provided with a grenade-throwing chamber that is open at both ends, and the side wall of the aforementioned grenade launcher body 1 is provided with an opening 2 that communicates with the aforementioned grenade-throwing chamber;

[0035] The release device includes a baffle 3 and a servo motor 4. The baffle 3 is driven to connect with the servo motor 4. The central protrusion of the baffle 3 is inserted into the throwing chamber along the opening 2 and abuts against the fire extinguishing grenade to be thrown, so as to lock the fire extinguishing grenade to be thrown into the throwing chamber.

[0036] The aforementioned servo motor 4 can drive the aforementioned baffle 3 to move, thereby releasing the locking of the aforementioned central protrusion on the aforementioned fire extinguishing projectile to be thrown.

[0037] The above structure is hinged to the baffle 3 and the servo motor 4. The central protrusion of the baffle 3 is inserted into the opening 2, so that when loading the device, the fire extinguishing bullet is put into the upper end of the grenade launcher body 1. The central part of the fire extinguishing bullet is blocked by the central protrusion of the baffle 3. The servo motor 4 controls the rotation of the baffle 3 to release the fire extinguishing bullet. This makes loading and changing the bullet of the device convenient and improves efficiency. Each grenade launcher body 1 is provided with a separate release device, so that each fire extinguishing bullet can be controlled when multiple fire extinguishing bullets are thrown.

[0038] The aforementioned drone-specific fire extinguishing grenade throwing device includes a fixed frame, and the aforementioned grenade launcher body (1) is set inside the aforementioned fixed frame.

[0039] The aforementioned fixing frame includes a first fastener and a second fastener. The first fastener is located at the lower part of the grenade launcher body 1, and the second fastener is located at the middle part of the grenade launcher body 1. The first fastener and the second fastener are connected by multiple first connecting rods 5. The first fastener, the second fastener, and the first connecting rods 5 make the grenade launcher body 1, which is locked in there, more stable, and less likely to fall apart when the drone drops the fire extinguishing bombs.

[0040] The aforementioned servo motor 4 is equipped with an output shaft 6, which is connected to a pull ring 7. The pull ring 7 is hinged to a pin 8. The first end of the pull ring 7 is connected to the first end of the pin 8, and the second end of the pin slides through the first fastener and abuts against the stop plate. The servo motor 4 controls the output shaft 6 to move up and down, which in turn drives the pull ring 7, which in turn drives the pin 8. The pin 8 is inserted into the first fastener, so that the pin 8 can only move in the up and down direction.

[0041] The aforementioned baffle 3 has a locking abutment groove on the side opposite to the aforementioned central protrusion;

[0042] When the second end of the aforementioned pin 8 is inserted into the aforementioned locking abutment groove, the aforementioned central protrusion abuts against the aforementioned fire extinguishing bomb to be thrown.

[0043] When the second end of the aforementioned pin 8 disengages from the aforementioned locking groove, the fire extinguishing grenade to be thrown can be pushed by gravity to move the aforementioned central protrusion along the aforementioned opening away from the aforementioned fire extinguishing grenade. That is, by pushing the pin up and down, the baffle moves laterally. When the pin is moving upward, the baffle abuts against the fire extinguishing grenade; when the pin is moving downward, the baffle moves away from the opening, and the fire extinguishing grenade is released under its own weight.

[0044] The aforementioned grenade launcher body 1 comprises multiple units, each equipped with a release device. The first fastener is formed by welding multiple first clamps 9 to a first frame 10, the number of which is the same as the number of grenade launcher bodies 1. The second fastener is formed by welding multiple second clamps 11 to a second frame 12, the number of which is the same as the number of grenade launcher bodies 1. The first clamps 9 engage with the grenade launcher bodies 1, and the second clamps 11 engage with the grenade launcher bodies 1. By clamping the grenade launcher bodies 1 with the clamps, a certain number of grenade launcher bodies 1 can be installed within the clamps according to actual needs; preferably, the number of grenade launcher bodies 1 is eight. Each of the eight grenade launcher bodies 1 is equipped with a release device, which enables individual grenade launcher control when all eight grenade launchers are firing.

[0045] The aforementioned servo motor 4 is detachably mounted on the aforementioned first frame 10.

[0046] The second frame 12 is provided with first locking pin male head 13 at both ends. The first locking pin male head 13 is engaged and electrically connected with the first locking pin female head. The first locking pin female head is provided on the drone frame.

[0047] The second frame 12 has a second locking pin male head 14 in the middle, which is engaged and electrically connected to a second locking pin female head. The second locking pin female head is located on the drone frame. Through the first locking pin male head 13, the first locking pin female head, the second locking pin male head 14, and the second locking pin female head, the drone-specific fire extinguishing bomb throwing device can be detachably connected to the drone frame, and the detachment speed is fast. Through the electrical connection of the locking pins, the drone frame can transmit electrical signals to the drone-specific fire extinguishing bomb throwing device through the locking pins to control the throwing of fire extinguishing bombs.

[0048] The aforementioned fixing frame also includes a third fastener 15, which is located at the top of the grenade launcher body 1 and is connected to the second fastener via a second connecting rod. The third fastener 15 further enhances the stability of the device.

[0049] A drone is also provided, including the aforementioned drone-specific fire extinguishing bomb throwing device.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
