Technical Field

[0001] This utility model belongs to the field of fire-fighting drone technology, specifically a drone bomb-dropping fire extinguishing bomb compartment for fire fighting. Background Technology

[0002] Firefighting drones are unmanned aircraft controlled by radio remote control equipment and onboard programs. They are mainly used in the field of firefighting and rescue. They include various types, such as unmanned helicopters, fixed-wing aircraft, multi-rotor aircraft, unmanned airships, and unmanned paragliders. As a new industrial technology, drone firefighting has been widely used in various fields. When firefighting drones are carrying out firefighting work, they are usually equipped with a bomb-type fire extinguishing chamber on their bottom for firefighting.

[0003] In a Chinese patent (authorized public number: CN106043698B) describing a drone-mounted fire extinguishing bomb delivery compartment and its delivery method, the inner chamber of the delivery compartment is divided into independent delivery compartments by transverse and longitudinal partitions, with delivery compartment doors at the bottom of each compartment. Door servos are installed on the outer wall of the delivery compartment and on the bottom of the sides adjacent to the delivery compartment doors. The delivery method of the drone-mounted fire extinguishing bomb delivery compartment includes the following steps: 1. Delivery compartment installation; 2. Loading of bombs; 3. Drone takeoff. The deployment process involves controlling the deployment command. The drone receiver receives the launch command and sends it to the door servo. The door servo controls the door latch shaft to rotate, thereby driving the door latch to rotate and open the fire extinguishing bomb deployment compartment to deploy fire extinguishing bombs one by one or simultaneously. This device is quick to load, has high deployment efficiency, no shaking, and safe and reliable deployment. However, the device has an overly complex structure, high equipment investment costs, and troublesome subsequent maintenance. In addition, the overall counterweight of the device is large, which increases the difficulty of drone flight, and the deployment control is not stable enough, affecting the deployment effect of fire extinguishing bombs.

[0008] As a further embodiment of this utility model: the outer wall of the arc-shaped card strip is provided with a rolling groove, and a ball is rolled in the rolling groove, the outer surface of the ball being abutted against the inner wall of the bomb compartment.

[0009] As a further improvement of this utility model, a maintenance cover is fixedly connected to one side of the bomb bay body by fasteners.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the setting of a cylindrical bomb bay, servo motor, rotating rod, turntable, arc-shaped locking strip, bomb placement slot, and door opening mechanism, first activates the micro push rod to extend, which pushes the door panel to rotate and open the bomb release port. Then, the servo motor drives the rotating rod to rotate. When the fire extinguishing bomb in the corresponding bomb placement slot rotates to the bomb release port, the arc-shaped locking strip automatically swings down and opens due to gravity. The fire extinguishing bomb in the bomb placement slot automatically falls from the bomb release port due to gravity. Then, the turntable continues to rotate. The arc-shaped locking strip is restricted by the bomb bay and automatically swings in the circular motion until it fits with the bomb placement slot to achieve a tight lock. This structure can realize automatic and orderly bomb release. It has a simple structure, low manufacturing cost, convenient maintenance, lightweight size, convenient carrying and flight, and stable and orderly bomb release with high safety.

[0012] 2. This utility model, by setting up a pop-out mechanism, can hold the fire extinguishing bomb tightly when the arc-shaped locking strip is in contact with the bomb slot. At this time, the compression spring is squeezed and contracted by the arc-shaped push block to generate elastic force. Using the elastic force of the compression spring, the arc-shaped push block is pushed back to hold the fire extinguishing bomb tightly, making the fire extinguishing bomb more securely locked. When the fire extinguishing bomb rotates to the corresponding bomb-throwing port, the elastic force of the compression spring causes the arc-shaped push block to automatically pop the fire extinguishing bomb out of the bomb slot and drop it from the bomb-throwing port to extinguish the fire, making the deployment more convenient.

[0019] Please see Figures 1-4This embodiment provides a drone-mounted bomb disposal bomb bay for firefighting, comprising a cylindrical bomb bay body 1, a remote control mechanism mounted on the bomb bay body 1, a servo motor 2 fixedly connected to the rear center of the bomb bay body 1, the main shaft of the servo motor 2 penetrating into the bomb bay body 1 and fixedly connected to a rotating rod 3, a turntable 4 fixedly mounted on the rotating rod 3, and several equally spaced bomb placement slots 5 arranged around the outer wall of the turntable 4, each bomb placement slot 5 having a ejection mechanism on its inner bottom wall, and an arc-shaped locking strip 7 rotatably connected to the edge of the turntable 4 and the opening end of each bomb placement slot 5 via a rotating shaft 6, the bottom of the bomb bay body 1 having a bomb disposal port 8, and the opening end of the bomb disposal port 8 having a door opening mechanism, the remote control mechanism being connected to the servo motor 2 and the door opening mechanism respectively. The structure is electrically connected, and the top of the bomb compartment 1 is fixedly connected to a mounting bracket 20 for connection with the UAV. When bombing is required, the door opening mechanism opens the bombing port 8, and the servo motor 2 starts to drive the rotating rod 3 to rotate. When the fire extinguishing bomb in the corresponding bomb placement slot 5 rotates to the bombing port 8, the arc-shaped locking strip 7 automatically swings down and opens due to gravity. The fire extinguishing bomb in the bomb placement slot 5 automatically falls from the bombing port 8 due to gravity for bombing. Then, the turntable 4 continues to rotate. The arc-shaped locking strip 7 is restricted by the bomb compartment 1 and automatically swings in the circular motion until it fits with the bomb placement slot 5 to achieve a tight lock. This structure can realize automatic and orderly bombing. It has a simple structure, low manufacturing cost, convenient maintenance, light size, convenient carrying and flight, and stable and orderly bombing, and high safety in use.

[0020] like Figure 1 As shown: The remote control mechanism includes a PLC controller 9, a battery module 10, and a signal transmitter 11, which are respectively fixed on the outer wall of the bomb bay 1. The PLC controller 9 is electrically connected to the battery module 10 and the signal transmitter 11. The battery module 10 provides power, the PLC controller 9 provides control, and the signal transmitter 11 can be remotely controlled. All electrical devices are connected to the PLC controller 9 for control. The circuit involved is existing technology, which can be fully implemented by those skilled in the art and does not need to be elaborated.

[0021] like Figure 4 As shown: The ejection mechanism includes an installation groove 12 formed in the bottom wall of the ejection slot 5. A compression spring 13 is fixedly connected to the inner wall of the installation groove 12. One end of the compression spring 13 extends into the ejection slot 5 and is fixedly connected to an arc-shaped push block 14. When the arc-shaped locking strip 7 is in contact with the ejection slot 5, it can press the fire extinguishing bomb against the wall. At this time, the compression spring 13 is compressed and contracted by the arc-shaped push block 14 to generate elastic force. Using the elastic force of the compression spring 13, the arc-shaped push block 14 is pushed back to press the fire extinguishing bomb against the wall, making the fire extinguishing bomb more securely locked. When the fire extinguishing bomb rotates to the corresponding ejection port 8, the elastic force of the compression spring 13 causes the arc-shaped push block 14 to automatically eject the fire extinguishing bomb from the ejection slot 5 and drop it from the ejection port 8 to extinguish the fire, making the ejection more convenient.

[0022] like Figure 1 and Figure 2 As shown: The door opening mechanism includes a door plate 15 hinged to one side of the opening end of the bomb release port 8 and a miniature push rod 16 hinged to the front side wall of the bomb compartment 1. The lower end of the miniature push rod 16 is hinged to the front side wall of the door plate 15. The PLC controller 9 controls the miniature push rod 16 to extend, which can push the door plate 15 to rotate and open the bomb release port 8. Conversely, the miniature push rod 16 retracts, which can drive the door plate 15 to fit with the bomb release port 8 for sealing and closing.

[0023] like Figure 4 As shown: The outer wall of the arc-shaped card strip 7 is provided with a groove 17, and a ball 18 is rolled in the groove 17. The outer surface of the ball 18 is set against the inner wall of the bomb compartment 1. The friction between the ball 18 and the inner wall of the bomb compartment 1 can eliminate the friction between the arc-shaped card strip 7 and the inner wall of the bomb compartment 1, making it easier for the turntable 4 to rotate.

[0024] like Figure 1 As shown: A maintenance cover 19 is fixedly connected to one side of the missile compartment 1 by fasteners, through which the interior of the missile compartment 1 is inspected.

[0025] Working principle: When bombing is required, the PLC controller 9 controls the micro push rod 16 to extend, which can push the door plate 15 to rotate and open the bombing port 8. The servo motor 2 is started to drive the rotating rod 3 to rotate. When the fire extinguishing bomb in the corresponding bombing slot 5 rotates to the bombing port 8, the arc-shaped locking strip 7 automatically swings down and opens due to gravity. The fire extinguishing bomb in the bombing slot 5 automatically falls from the bombing port 8 due to gravity for bombing. Then, the turntable 4 continues to rotate. The arc-shaped locking strip 7 is restricted by the bomb compartment 1 and automatically swings in the circular motion until it fits with the bombing slot 5 to achieve locking. This structure can realize automatic and orderly bombing. It has a simple structure, low manufacturing cost, convenient maintenance, light size, convenient carrying and flight, and stable and orderly bombing, and high safety in use.

[0026] When the arc-shaped locking strip 7 is in contact with the ammunition slot 5, it can hold the fire extinguishing bomb tightly. At this time, the compression spring 13 is compressed and contracted by the arc-shaped push block 14 to generate elastic force. Using the elastic force of the compression spring 13, the arc-shaped push block 14 is pushed back to hold the fire extinguishing bomb tightly, making the fire extinguishing bomb more securely locked. When the fire extinguishing bomb rotates to the corresponding ammunition port 8, the elastic force of the compression spring 13 causes the arc-shaped push block 14 to automatically eject the fire extinguishing bomb from the ammunition slot 5 and drop it from the ammunition port 8 to extinguish the fire, making the deployment more convenient.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
