A vehicle-mounted firefighting drone that is easy to take off quickly

Abstract

This invention relates to a firefighting drone, and more particularly to a vehicle-mounted firefighting drone that facilitates rapid takeoff. The vehicle-mounted firefighting drone includes a fire truck body; a casing structure is mounted on top of the fire truck body, within which multiple drone stations are installed, and drone bodies are placed on the drone stations. When the casing structure is opened, the drone bodies are moved outside the casing structure via the drone stations, thus preventing obstruction during takeoff and facilitating takeoff. During the downward movement of the lifting plate, a spring resets, causing a moving plate and a wedge plate to close. The moving plate and wedge plate push the drone body back to its placement location and simultaneously compress the drone body, making it more stable during transport. An ejection mechanism can launch the drone body, further facilitating takeoff.

Description

Technical Field

[0001] This invention relates to a firefighting drone, and more particularly to a vehicle-mounted firefighting drone that is easy to take off quickly. Background Technology

[0002] With the acceleration of urbanization and the surge in the number of high-rise buildings, fire rescue faces increasingly severe challenges. Traditional ground-based firefighting equipment, limited by height and operating space, is difficult to effectively respond to high-rise fires or fires in complex terrain. Drone technology, due to its flexibility, maneuverability, and wide field of view, is gradually being introduced into the firefighting field, becoming an important tool for auxiliary reconnaissance, dropping fire extinguishing bombs, and even directly spraying fire extinguishing agents.

[0003] Currently, vehicle-mounted firefighting drones are typically carried by fire trucks and stored inside the truck bed or in dedicated storage compartments for rapid deployment to fire scenes. However, existing methods for deploying and recovering vehicle-mounted drones have significant technical flaws, severely impacting the timeliness and automation of rescue efforts. First, the takeoff and deployment process is cumbersome and space-constrained. Traditional vehicle-mounted drones require firefighters to open the vehicle's doors or storage compartments before they can be used. This process not only wastes valuable manual time, but more importantly, the opened doors or compartments often occupy space above or behind the vehicle, creating physical obstacles.

[0004] Secondly, landing, recovery, and positioning are difficult, and there is a lack of an automatic return mechanism. When the drone returns after completing a firefighting or reconnaissance mission, it is difficult for the drone to accurately and autonomously land at the preset position inside the vehicle because the vehicle platform is not on a fixed ground (there may be slight shaking) and the GPS signal is blocked by thick smoke or tall buildings at the fire scene.

[0005] Therefore, there is an urgent need to develop a vehicle-mounted firefighting drone that can automatically adjust back to its placement point after landing, and automatically move out of the equipment when the vehicle compartment is opened, without affecting the drone's takeoff, so as to facilitate rapid takeoff. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a vehicle-mounted fire-fighting drone that automatically adjusts back to the placement point after landing, and automatically moves out of the equipment after the vehicle compartment is opened, without the vehicle compartment affecting the drone's takeoff, which facilitates rapid takeoff.

[0007] The technical solution of the present invention is as follows: a vehicle-mounted fire-fighting drone that is easy to take off quickly, comprising a fire truck body, a chassis structure and a drone platform. The chassis structure is located on the top of the fire truck body. Multiple drone platforms are installed inside the chassis structure. A drone body is placed on the drone platform. After the chassis structure is opened, the drone platform sends the drone body out of the chassis structure. After the drone body lands on the drone platform, the drone platform moves the drone body back to the placement point.

[0008] As a preferred embodiment of the present invention, the chassis structure includes guide blocks installed at the four corners of the top of the fire truck body. A guide optical shaft is slidably arranged inside the guide block along its axial direction. A box cover is connected between the front and rear ends of the guide optical shaft on the same side. A drive component for opening the box cover is installed between the guide block and the box cover.

[0009] As a preferred embodiment of the present invention, the driving component includes racks symmetrically mounted on the inner wall of the cover, the racks being parallel to the guide optical axis, and a first motor being provided on the top of each guide block, the output shaft of which is connected to a gear meshing with an adjacent rack.

[0010] As a preferred embodiment of the present invention, the drone platform includes multiple lifting mechanisms installed on the top of the fire truck body, and a positioning mechanism for positioning the drone is installed on the top of the lifting mechanism.

[0011] As a preferred embodiment of the present invention, the lifting mechanism includes a bidirectional screw rod embedded in the top of the fire truck body. Two bidirectional screw rods are arranged as a group, and multiple groups are installed. A second motor is installed at one end of each bidirectional screw rod. Threaded blocks are threadedly connected to the two threaded sections of each bidirectional screw rod. The threaded blocks are slidably connected to the top of the fire truck body. A set of guide rods is provided on the top of the fire truck body between each group of bidirectional screw rods. A lifting plate is vertically slidably connected between each group of guide rods. A hinge rod is rotatably connected between the side of the lifting plate and the threaded block. A through hole is vertically opened in the middle of each lifting plate.

[0012] As a preferred embodiment of the present invention, the positioning mechanism includes a set of movable plates slidably mounted on the top of the lifting plate. Wedge-shaped plates are symmetrically arranged on the inner side of each movable plate, with the inclined surface of each wedge-shaped plate facing inward. A spring connects the movable plate to the lifting plate. First fixed pulleys are symmetrically arranged on the front and rear sides of each movable plate. A first pull rope is wound around the first fixed pulley. One end of the first pull rope is connected to the movable plate, and the other end is connected to the movable plate.

[0013] As a preferred embodiment of the present invention, it further includes a catapult mechanism installed in the middle of the lifting plate, with the unmanned aerial vehicle body placed on top of the catapult mechanism. The catapult mechanism includes a mounting groove in the middle of the lifting plate, with elastic telescopic rods symmetrically arranged in the mounting groove. A connecting plate is connected between the top ends of the elastic telescopic rods. Second fixed pulleys are symmetrically arranged in the mounting groove. A wire-buying groove is extended in the lifting plate below the second fixed pulleys. A pull rope is wound around the second fixed pulley. The top end of the pull rope is connected to the bottom of the connecting plate, and the other end of the pull rope extends into the wire-buying groove and is connected to the end of the wire-buying groove. A vertical hole is opened in the lifting plate above the wire-buying groove. The vertical hole is close to the outer end of the wire-buying groove, and a pressure rod is slidably connected in the vertical hole.

[0014] As a preferred embodiment of the present invention, both the upper and lower ends of the pressure rod are semi-circular, the bottom end of the pressure rod is in contact with the pull rope, the top end of the pressure rod extends out of the lifting plate, and the pressure rod is on the moving path of the moving plate.

[0015] As a preferred embodiment of the present invention, it further includes a connecting rod installed between the bottom brackets of the unmanned aerial vehicle body and a limiting block installed on the inner side of the moving plate, wherein the limiting block is at the top of the connecting rod.

[0016] As a preferred embodiment of the present invention, the bottom of the inner end of the limiting block is an inclined surface.

[0017] Beneficial effects: This invention uses a drone platform to move the drone body outside the chassis structure, so the drone body is not obstructed by the chassis structure when taking off, facilitating takeoff; during the downward movement of the lifting plate, the spring returns to its original position, causing the moving plate and wedge plate to close, pushing the drone body back to its placement location and simultaneously pressing it down, making the drone body more stable during transportation; the ejection mechanism can eject the drone body, facilitating takeoff; the limiting block at the top of the connecting rod vertically limits and fixes the drone body, making it more stable during transportation.

Detailed Implementation

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0030] Example: A vehicle-mounted firefighting drone that facilitates rapid takeoff, such as Figures 1-8As shown, the system includes a fire truck body 1, a chassis structure 2, and drone stations 3. The fire truck body 1 extends horizontally, with its front facing right. The chassis structure 2 is located on top of the fire truck body 1 and can slide open forward and backward. Two drone stations 3 are installed inside the chassis structure 2, and drone bodies 34 are placed on the drone stations 3. After the chassis structure 2 is opened, the drone stations 3 send the drone bodies 34 out of the chassis structure 2, ensuring that the fire truck body does not affect the takeoff of the drone bodies 34. After the drone bodies 34 land on the drone stations 3, the drone stations 3 move the drone bodies 34 back to their placement points, ensuring that the drone bodies 34 are in the same position each time they are used. The fire truck body 1 moves to the fire extinguishing location, then the chassis structure 2 opens, and the drone stations 3 send the drone bodies 34 out of the equipment. The drone bodies 34 then take off and move to the fire extinguishing location to carry out fire extinguishing work. After the drone bodies 34 have completed their fire extinguishing work, they land on the drone stations 3, which then send the drone bodies 34 back into the chassis structure 2 and move them back to their placement points. Finally, the chassis structure 2 is closed.

[0031] like Figure 3 As shown, the chassis structure 2 includes guide blocks 21, guide optical shafts 22, and a cover 26. Guide blocks 21 are fixedly connected to the four corners of the top of the fire truck body 1. Guide optical shafts 22 are slidably arranged back and forth along their axial direction inside the guide blocks 21. The cover 26 is connected between the front and rear ends of the guide optical shafts 22 on the same side. A drive component for opening the cover 26 is installed between the guide blocks 21 and the cover 26. By controlling the operation of the drive component, the cover 26 is moved back and forth to close or open.

[0032] like Figure 3 As shown, the driving component includes a rack 23, a first motor 24, and a gear 25. Racks 23 are provided on both the left and right sides of the inner wall of the box cover 26, extending forward and backward. The top of the guide block 21 is fixed with a first motor 24 by bolts. The output shaft of the first motor 24 is connected to a gear 25 that meshes with the adjacent rack 23. By controlling the rotation of the first motor 24, the gear 25 is driven to rotate, thereby driving the rack 23 to move forward or backward, thereby driving the box cover 26 to move forward or backward, so that the box cover 26 closes or opens.

[0033] like Figures 4-8As shown, the drone platform 3 includes a lifting mechanism 31 and a positioning mechanism 32. Lifting mechanisms 31 are installed on both the left and right sides of the top of the fire truck body 1. A positioning mechanism 32 for positioning the drone is installed on the top of each lifting mechanism 31. The lifting mechanism 31 includes a two-way lead screw 311, a second motor 312, a threaded block 313, a guide rod 314, a lifting plate 315, and a hinge rod 316. Two sets of two-way lead screws 311 are embedded in the top of the fire truck body 1. The two-way lead screws 311 are arranged in pairs, extending in a front-to-back direction. The system is dynamically installed, with a second motor 312 mounted on the front end of each bidirectional screw 311 via a coupling. The bottom of the second motor 312 is fixedly connected to the top of the fire truck body 1 via bolts. Threaded blocks 313 are threadedly connected to both ends of the bidirectional screw 311, and the threaded blocks 313 are slidably connected to the top of the fire truck body 1. A set of guide rods 314 is installed on the top of the fire truck body 1 between each set of bidirectional screws 311, and a lifting plate 315 is vertically slidably connected between each set of guide rods 314. The sides of the lifting plate 315... A hinge rod 316 is rotatably connected to each threaded block 313. During the rotation of the bidirectional screw 311, the threaded block 313 closes or opens, causing the bottom end of the hinge rod 316 to close or open, thereby driving the lifting plate 315 to rise or fall. Each lifting plate 315 has a vertical through hole 317 in the middle, through which the fire extinguishing water pipe passes and connects to the unmanned aerial vehicle body 34. The positioning mechanism 32 includes a moving plate 321, a wedge plate 322, a spring 323, a first fixed pulley 324, and a first pull rope. 325, the top of the lifting plate 315 is slidably connected to the moving plate 321. The inner side of the moving plate 321 is symmetrically provided with wedge plates 322, the inclined surface of the wedge plates 322 faces inward. A spring 323 is connected between the moving plate 321 and the lifting plate 315. The front and rear sides of the moving plate 321 are symmetrically embedded with the first fixed pulley 324. The first fixed pulley 324 is wound with the first pull rope 325. One end of the first pull rope 325 is connected to the moving plate 321, and the other end is connected to the moving plate 321.

[0034] Unmanned Aerial Vehicle (UAV) Station 3: After the chassis structure 2 is opened, the second motor 312 is controlled to rotate, which in turn drives the bidirectional lead screw 311 to rotate, thereby causing the threaded blocks 313 to separate. This causes the bottom end of the hinge rod 316 to separate, and the hinge rod 316 rises, driving the lifting plate 315 upward, thus moving the UAV body 34 outside the chassis structure 2 for takeoff. Simultaneously, as the lifting plate 315 moves upward, the first pull rope 325 causes the moving plate 321 to separate, the spring 323 is stretched, and the moving plate 321 releases the UAV body 34. The moving plate 321 does not affect the takeoff of the UAV body 34. After the UAV body 34 completes the firefighting operation... The drone body 34 lands on top of the lifting plate 315. At this time, the second motor 312 is controlled to reverse, which drives the bidirectional lead screw 311 to reverse, thereby driving the threaded blocks 313 to close together. This causes the bottom end of the hinge rod 316 to close. The hinge rod 316 tilts, causing the lifting plate 315 to move downward, so that the drone body 34 returns to the chassis structure 2. During the downward movement of the lifting plate 315, the spring 323 resets, causing the moving plate 321 and the wedge plate 322 to close together. The moving plate 321 and the wedge plate 322 push the drone body 34 back to the placement location and press the drone body 34 to make it more stable during transportation.

[0035] like Figure 9As shown, it also includes a catapult mechanism 33 installed in the middle of the lifting plate 315. The unmanned aerial vehicle body 34 is placed on top of the catapult mechanism 33. The catapult mechanism 33 includes an elastic telescopic rod 332, a connecting plate 333, a second fixed pulley 334, a second pull rope 336, and a pressure rod 338. The lifting plate 315 has a mounting groove 331 in the middle. Elastic telescopic rods 332 are symmetrically and vertically arranged in the mounting groove 331. The top ends of the elastic telescopic rods 332 are connected to the top ends of the elastic telescopic rods 332. The second fixed pulleys 334 are symmetrically arranged in the mounting groove 331. A wire embedding groove 335 is extended in the lifting plate 315 below the second fixed pulleys 334. The second pull rope 336 is wound around the second fixed pulleys 334. The top end of the second pull rope 336 is connected to the bottom of the connecting plate 333. The other end of the second pull rope 336 extends into the wire embedding groove 335 and is connected to the end of the wire embedding groove 335. The wire embedding groove 335 is located above the wire embedding groove 335. A vertical hole 337 is provided on the lifting plate 315. The vertical hole 337 is close to the outer end of the buried wire groove 335. A pressure rod 338 is slidably connected in the vertical hole 337. The upper and lower ends of the pressure rod 338 are semi-circular. The bottom end of the pressure rod 338 contacts the second pull rope 336. The top end of the pressure rod 338 extends out of the lifting plate 315. The pressure rod 338 is on the moving path of the moving plate 321. When the moving plates 321 separate, they will contact the top of the pressure rod 338 and drive the pressure rod 338 to move downward, thereby pushing the second pull rope 336 below the pressure rod 338 to bend downward, causing the connecting plate 333 to move downward. The elastic telescopic rod 332 deforms. When the moving plate 321 leaves the top of the pressure rod 338, the drone body 34 just moves out of the chassis structure 2. At the same time, the drone body 34 starts, the elastic telescopic rod 332 resets, and drives the connecting plate 333 to move upward and reset, ejecting the drone body 34.

[0036] like Figure 10 As shown, it also includes a connecting rod 341 installed between the bottom brackets of the unmanned aerial vehicle body 34 and a limiting block 342 installed on the inner side of the moving plate 321. The limiting block 342 is on top of the connecting rod 341, thereby vertically limiting and fixing the unmanned aerial vehicle body 34, making the unmanned aerial vehicle body 34 more stable during transportation. When the moving plate 321 is separated, the limiting block 342 moves away from the top of the connecting rod 341, releasing the limiting and fixing of the unmanned aerial vehicle body 34. The bottom of the inner end of the limiting block 342 is inclined, so as to facilitate the movement of the limiting block 342 to the top of the connecting rod 341.

[0037] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
