Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguishing bomb delivery devices, and particularly to an unmanned aerial vehicle (UAV) fire extinguishing bomb delivery device. Background Art

[0002] A fire extinguishing bomb is a special device for extinguishing fires, usually used in fire fighting operations. Its main function is to be dropped above or around the fire source and quickly release the fire extinguishing agent to suppress or extinguish the open fire. Usually, the fire extinguishing bomb is installed on a UAV, and then the UAV is controlled to fly above the fire source to drop the fire extinguishing bomb. When the fire extinguishing bomb comes into contact with the fire source, the fire source is controlled.

[0003] However, when some existing UAV fire extinguishing bomb delivery devices are actually used, in order to be used more effectively, more fire extinguishing bombs are usually placed on the UAV and the fire extinguishing bombs are dropped sequentially during use. However, the existing UAV fire extinguishing bomb delivery devices can drop the fire extinguishing bombs sequentially, resulting in an unbalanced gravity on the UAV after the fire extinguishing bombs are dropped, which will affect the flight trajectory of the UAV. At the same time, it will also increase the difficulty of controlling the UAV and affect the accuracy of dropping the next fire extinguishing bomb. Therefore, the above problems need to be solved. Summary of the Invention

[0004] Based on the technical problems existing in the background art, the present invention proposes a UAV fire extinguishing bomb delivery device.

[0005] A UAV fire extinguishing bomb delivery device proposed by the present invention includes a UAV body, a fixed box, and mounting blocks. A monitoring device is installed at the bottom of the UAV body. A connecting plate is fixedly connected to the bottom of the UAV body. The fixed box is fixedly connected to the bottom of the connecting plate. A moving groove is horizontally opened at the bottom of the fixed box. A moving frame is horizontally slidably connected inside the moving groove. A sliding mechanism for sliding the moving frame is provided inside the moving groove. A plurality of mounting openings are vertically penetrated through the surface. A plurality of mounting blocks are provided. The plurality of mounting blocks are respectively installed inside the plurality of mounting openings. Limiting mechanisms are provided at the bottoms of the plurality of mounting blocks. Through the arrangement of the plurality of moving frames, the moving frames can be horizontally slid during use, so that the plurality of fire extinguishing bomb bodies can be slid together. When the inclined blocks at the tops of each moving frame contact the bottom of the partition plate, the inclined blocks will be pressed downward, and at the same time, the vertical sliding rod will be horizontally slid through the vertical sliding block, so that the fire extinguishing bomb bodies hanging on the card strips are released. At the same time, sliding the plurality of fire extinguishing bomb bodies will also keep the center of gravity of the plurality of fire extinguishing bomb bodies at the bottom of the UAV body.

[0006] Preferably, the sliding mechanism includes a sliding plate. Horizontal sliding grooves are horizontally formed on both opposite sides inside the moving groove. A plurality of rollers are symmetrically installed on both sides of the surface of the moving frame. The plurality of rollers are respectively connected to the inside of the two sliding grooves in a rolling manner. A partition plate is vertically and fixedly connected to the top inside the moving groove. The partition plate is arranged on the top of the moving frame. The sliding plate is fixedly connected to one end of the moving frame. The sliding plate is arranged in an L shape. The sliding plate is slidably connected between one end inside the moving groove and the partition plate. A lead screw nut is installed inside the sliding plate. A lead screw is rotatably connected to the inside of the moving groove. The lead screw is horizontally arranged. One end of the lead screw is rotatably connected to the surface of the partition plate. The other end of the partition plate is rotatably sleeved at one end inside the moving groove. The lead screw is rotatably sleeved inside the lead screw nut. The lead screw nut is matched with the lead screw. A servo motor is installed on the surface of one end of the moving frame. The output end of the servo motor is fixedly connected to one end of the lead screw, which is used to limit the horizontal sliding of the moving frame inside the fixed box, so as to drive a plurality of fire extinguishing bomb bodies to slide together at the same time.

[0007] Furthermore, the limiting mechanism includes a vertical sliding rod. One end of the bottom of the mounting block is vertically and fixedly connected with a vertical plate. A first vertical groove is vertically formed on the surface of the vertical plate. A horizontal groove is horizontally formed at the other end of the bottom of the mounting block. Horizontal limiting grooves are formed on both opposite sides inside the horizontal groove. The vertical sliding rod is horizontally slidably connected to the inside of the horizontal groove. The vertical sliding rod is vertically arranged. Second limiting blocks are horizontally slidably connected to the inside of the two horizontal limiting grooves away from each other. The two second limiting blocks are fixedly connected to the surface of the vertical sliding rod. Second springs are fixedly connected to the sides of the two second limiting blocks away from the vertical plate. The two second springs are respectively arranged inside the two horizontal limiting grooves. The other ends of the two second springs are respectively fixedly connected to one ends inside the two horizontal limiting grooves away from the vertical plate, which is used to limit the horizontal sliding of the vertical sliding rod inside the mounting block, and at the same time drive the clamping strip to slide together, so as to open between the vertical sliding rod and the vertical plate.

[0008] Preferably, a rotating groove is formed at the bottom end of the vertical sliding rod. A support plate is vertically and fixedly connected to the bottom end of the vertical sliding rod. The support plate is arranged at the bottom of the rotating groove. Circular grooves are formed on both opposite sides inside the rotating groove. A rotating column is rotatably connected to the inside of the rotating groove. A clamping strip is fixedly connected to the surface of the rotating column. One end of the clamping strip is slidably connected to the inside of the first vertical groove. Shafts are fixedly connected to both ends of the rotating column. The two shafts are respectively rotatably sleeved on both opposite sides inside the two circular grooves. Torsion springs are arranged on the surfaces of the two shafts. The two ends of the two torsion springs are respectively fixedly connected to both ends of the rotating column and both opposite sides of the two circular grooves. A fire extinguishing bomb body is arranged at the bottom of the mounting block. A fixing ring is fixedly connected to the top of the fire extinguishing bomb body. The fixing ring is arranged on the top of the clamping strip, which is used to limit the rotation of the clamping strip inside the vertical sliding rod, so as to close between the vertical sliding rod and the vertical plate, and then the fire extinguishing bomb body can be hung.

[0009] Further, a second vertical groove is vertically formed inside the mounting block. The bottom end of the second vertical groove is arranged inside the horizontal groove. Opposite sides inside the second vertical groove are both provided with vertical limiting grooves. Inside both of the vertical limiting grooves, sliding rods are vertically and fixedly connected. Inside the second vertical groove, a vertical sliding block is vertically slidably connected. The top of the vertical sliding block is fixedly connected with an inclined block. Both sides of the inclined block are inclined. Inside both of the vertical limiting grooves, first limiting blocks are vertically slidably connected. The two first limiting blocks are respectively slidably sleeved on the surfaces of the two sliding rods. The two first limiting blocks are respectively fixedly connected to symmetric two sides of the surface of the vertical sliding block. First springs are sleeved on the surfaces of both of the sliding rods. The top ends of the two first springs are respectively fixedly connected to the bottoms of the two first limiting blocks. The bottom ends of the two first springs are respectively fixedly connected to the inner bottoms of the two vertical limiting grooves, which are used to limit the up-and-down sliding of the inclined block and the vertical sliding block, and thus a pushing effect on the vertical sliding rod can be generated during the downward sliding process.

[0010] Preferably, both ends of the bottom of the partition board are inclined. The inclined block cooperates with the partition board. One end of the top of the vertical sliding rod is inclined. The bottom end of the vertical sliding block is inclined. The bottom end of the vertical sliding block cooperates with the top of the vertical sliding rod, which is used to enable the vertical sliding block to slide downward simultaneously when the inclined block passes through the bottom of the partition board.

[0011] In the present invention, by driving the servo motor to drive the lead screw to rotate, with the cooperation of the lead screw nut and simultaneously under the connection of the sliding plate, the moving frame will slide towards one end close to the servo motor. Subsequently, the inclined block on the top of the mounting block will contact the partition board. At the same time, continuous sliding will press the surface of the inclined block, causing the inclined block and the vertical sliding block to slide downward, and simultaneously compressing the two first springs. During the downward sliding process of the inclined block, due to the inclined setting at the bottom of the inclined block, the vertical sliding rod will slide horizontally, and at the same time, the two second springs will be compressed, and the latch will also be driven to slide simultaneously. At this time, the fire extinguishing bomb body hung on the latch will fall, thereby performing bomb throwing for fire extinguishing. Subsequently, the sliding of the moving frame can be continued, so that multiple fire extinguishing bomb bodies at the bottom of the moving frame are sequentially put in.

[0012] During the use process, when the moving frame is sliding, multiple fire extinguishing bomb bodies at the bottom of the moving frame will also slide together, so that the weight received by the bottom of the unmanned aerial vehicle body can be kept more balanced, preventing the flight of the unmanned aerial vehicle body from being affected.

[0029] In a preferred embodiment, a second vertical groove 55 is vertically formed inside the mounting block 5. The bottom end of the second vertical groove 55 is disposed inside the horizontal groove 53. Vertical limiting grooves 56 are formed on both opposite sides inside the second vertical groove 55. Slide bars 57 are vertically and fixedly connected inside both of the two vertical limiting grooves 56. A vertical slider 71 is vertically slidably connected inside the second vertical groove 55. An inclined block 7 is fixedly connected to the top of the vertical slider 71. Both sides of the inclined block 7 are inclined.

[0030] In a preferred embodiment, both ends of the bottom of the partition plate 24 are inclined. The inclined block 7 is matched with the partition plate 24.

Subsequently, during use, the driving servo motor 61 can be driven to drive the lead screw 6 to rotate. With the cooperation of the lead screw nut 42 and the connection of the sliding plate 41, the moving frame 4 will slide towards the end close to the servo motor 61. Subsequently, the inclined block 7 at the top of the mounting block 5 will contact the partition plate 24. At the same time, continuous sliding will press the surface of the inclined block 7, causing the inclined block 7 and the vertical sliding block 71 to slide downward, and at the same time, the two first springs 73 will also be compressed. During the downward sliding process of the inclined block 7, due to the inclined setting at the bottom of the inclined block 7, the vertical sliding rod 8 will horizontally slide, and at the same time, the two second springs 82 will also be compressed, and the clamping strip 9 will also be driven to slide together. At this time, the fire extinguishing bomb bodies 3 hung on the clamping strip 9 will fall off, so as to carry out bomb throwing for fire extinguishing. Subsequently, the moving frame 4 can be continuously slid, so that the multiple fire extinguishing bomb bodies 3 at the bottom of the moving frame 4 are sequentially put into use. During the sliding process of the moving frame 4, the multiple fire extinguishing bomb bodies 3 at the bottom of the moving frame 4 will also be slid together, so that the weight bearing at the bottom of the UAV body 1 can be kept more balanced, preventing the flight of the UAV body 1 from being affected.
