Description

Technical Field

[0001] This utility model relates to the field of high-altitude fire extinguishing equipment for drones, and in particular to a high-altitude fire extinguishing equipment for drones with a thermal imaging detection-assisted mechanical gripper. Background Technology

[0002] Unmanned aerial vehicle (UAV) high-altitude firefighting equipment is a modern special equipment that integrates aviation technology, firefighting technology, and intelligent control technology for high-altitude fire suppression. It is defined as: a device that uses a UAV as a carrier, carrying core components such as a fire extinguishing agent storage and spraying system, a fire detection system, and a flight control system, capable of autonomously or remotely controlling fire suppression missions in high-altitude environments. The main UAV of this equipment typically adopts a multi-rotor or fixed-wing structure, providing a stable flight platform for the entire system; the fire extinguishing agent storage and spraying system includes a storage tank, pressurization device, and nozzles, which can accurately release dry powder, water-based, and other fire extinguishing agents; the fire detection system integrates thermal imagers, high-definition cameras, and other equipment to achieve real-time monitoring and location of the fire scene.

[0003] To achieve precise location of fire sources and dynamic monitoring of the fire situation, high-altitude drone firefighting equipment is generally equipped with thermal imaging detection auxiliary equipment. This equipment captures thermal radiation signals from the fire scene to generate visual thermal images. When this equipment malfunctions, due to its deep integration with the drone's internal systems, maintenance personnel must first completely disassemble the drone to separate the module containing the thermal imaging equipment, increasing the difficulty of disassembly. This results in time-consuming and technically demanding equipment repairs, not only delaying the golden opportunity for fire rescue but also potentially damaging other components of the drone due to frequent and complex disassemblies. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a high-altitude fire extinguishing device for unmanned aerial vehicles with a thermal imaging detection-assisted mechanical gripper, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a high-altitude fire extinguishing device for unmanned aerial vehicles (UAVs) with a thermal imaging detection-assisted mechanical gripper. The device includes a UAV body, with two symmetrically arranged support frames fixedly mounted on the bottom of the UAV body. A dry ice fire extinguisher body is fixedly mounted on the bottom of the UAV body, located between the two support frames. A groove is formed on the bottom of the UAV body, and a frame is slidably connected to the inner wall of the groove. A locking plate is fixedly connected to the bottom of the frame, and the locking plate is fixedly connected to the UAV body by bolts. A bidirectional lead screw is rotatably connected to the inner wall of the frame via bearings. A first motor is fixedly connected to the side, and the output end of the first motor is fixedly connected to a bidirectional lead screw. Two symmetrically arranged drive plates are threadedly connected to the outer surface of the bidirectional lead screw. Two symmetrically arranged connecting plates are fixedly connected to the bottom surface of each drive plate. A clamping plate is fixedly connected between every two corresponding front and rear connecting plates. A U-shaped frame is provided between the two clamping plates. The left and right sides of the U-shaped frame are fixedly connected with locking pins. The left and right sides of the U-shaped frame are locked to the two clamping plates by locking pins. The thermal imaging detector body is rotatably connected to the inside of the U-shaped frame through bearings. The thermal imaging detector body is electrically connected to the UAV body.

[0007] Preferably, in any of the above embodiments, a second motor is fixedly connected to the back of the U-shaped frame, a spur gear is fixedly connected to the output end of the second motor, and an arc-shaped rack is fixedly connected to the back of the thermal imaging detector body, the arc-shaped rack meshing with the spur gear.

[0008] Preferably, in any of the above embodiments, a clearance groove is provided through the back of the U-shaped frame, and the spur gear is located inside the clearance groove.

[0009] Preferably, in any of the above solutions, the inner wall of the frame is fixedly connected to two symmetrically arranged guide rods, and both drive plates are slidably connected to the guide rods.

[0010] Preferably, one side of the locking plate has a plurality of symmetrically arranged connecting slots, and the connecting plate is slidably connected to the locking plate through the connecting slots.

[0011] Preferably, in any of the above solutions, the top of the frame is fixedly connected to two symmetrically arranged splicing plates, and the frame is snapped into the drone body through the two splicing plates.

[0012] Preferably, one side of the clamping plate has a snap-fit ​​hole, and the snap-fit ​​pin is slidably connected to the clamping plate through the snap-fit ​​hole.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. Addressing the complex maintenance issues of traditional drone-based high-altitude firefighting thermal imaging detection auxiliary equipment, this device achieves convenient assembly and disassembly through components such as the frame and locking plate. When the thermal imaging detector malfunctions, simply unscrew the bolts connecting the locking plate to the drone body to pull the frame, along with the thermal imaging detector, out of the groove at the bottom of the drone body. The U-shaped frame is engaged with the clamping plate via snap-fit ​​pins, and the drive plate is controlled by a first motor and a bidirectional lead screw for opening and closing, facilitating quick separation of the thermal imaging detector for inspection. This modular design avoids complete disassembly of the drone body, significantly shortening maintenance time, lowering the technical threshold for maintenance, reducing the risk of damage to other drone components caused by frequent and complex disassembly, and ensuring the equipment's availability during fire rescue operations.

[0015] 2. This drone-based high-altitude firefighting equipment achieves flexible and accurate fire detection through the coordinated operation of multiple components. After the drone flies above the fire, it starts the first motor, driving a bidirectional lead screw to rotate. The drive plate moves along the bidirectional lead screw under the guidance of the guide rod, adjusting the distance between the two clamping plates to accommodate different sized U-shaped frames and the thermal imaging detector body. Next, the second motor starts, and its output spur gear meshes with the arc-shaped rack on the back of the thermal imaging detector body, driving the thermal imaging detector body to rotate within the U-shaped frame and adjust the detection angle. The connecting slot on the locking plate cooperates with the connecting plate to ensure the stability of the clamping structure; the splicing plate at the top of the frame snaps into the drone body, ensuring the overall connection reliability. This design allows for rapid adjustment of the position and angle of the thermal imaging detector body according to the actual situation at the fire scene, accurately capturing thermal radiation signals, providing accurate data support for firefighting decisions, and improving firefighting efficiency and safety.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0024] like Figures 1 to 6 As shown, a high-altitude firefighting device for unmanned aerial vehicles (UAVs) with a thermal imaging detection-assisted mechanical gripper includes a UAV body 1. Two symmetrically arranged support frames 2 are fixedly mounted on the bottom of the UAV body 1. A dry ice fire extinguisher body 3 is fixedly mounted on the bottom of the UAV body 1, located between the two support frames 2. A groove 4 is formed on the bottom of the UAV body 1, and a frame 5 is slidably connected to the inner wall of the groove 4. A locking plate 6 is fixedly connected to the bottom of the frame 5 and is fixedly connected to the UAV body 1 by bolts. A bidirectional lead screw 7 is rotatably connected to the inner wall of the frame 5 via bearings. A first motor 8 is fixedly connected to one side of the frame 5. The output end is fixedly connected to the bidirectional lead screw 7. The outer surface of the bidirectional lead screw 7 is threaded with two symmetrically arranged drive plates 9. The bottom surface of each drive plate 9 is fixedly connected with two symmetrically arranged connecting plates 10. A clamping plate 11 is fixedly connected between each pair of front and rear corresponding connecting plates 10. A U-shaped frame 12 is arranged between the two clamping plates 11. The left and right sides of the U-shaped frame 12 are fixedly connected with locking pins 13. The left and right sides of the U-shaped frame 12 are locked with the two clamping plates 11 through locking pins 13. The thermal imaging detector body 14 is rotatably connected to the inside of the U-shaped frame 12 through bearings. The thermal imaging detector body 14 is electrically connected to the UAV body 1.

[0025] As an optional technical solution of this utility model, a second motor 15 is fixedly connected to the back of the U-shaped frame 12, and a spur gear 16 is fixedly connected to the output end of the second motor 15. An arc-shaped rack 17 is fixedly connected to the back of the thermal imaging detector body 14. The arc-shaped rack 17 meshes with the spur gear 16. When the drone arrives at the fire scene, the second motor 15 starts, driving the spur gear 16 to rotate. Through the meshing transmission with the arc-shaped rack 17, the thermal imaging detector body 14 is driven to rotate along an arc-shaped trajectory inside the U-shaped frame 12 to achieve multi-angle detection.

[0026] As an optional technical solution of this utility model, a clearance groove 18 is provided through the back of the U-shaped frame 12, and the spur gear 16 is located inside the clearance groove 18. The clearance groove 18 houses the spur gear 16, which on the one hand protects the spur gear 16 from external environmental interference and prevents dust and debris from entering and affecting the transmission effect; on the other hand, it effectively prevents the spur gear 16 from interfering with or colliding with other components during operation, and ensures the smoothness of the angle adjustment of the thermal imaging detector body 14.

[0027] As an optional technical solution of this utility model, the inner wall of the frame 5 is fixedly connected with two symmetrically arranged guide rods 19, and both drive plates 9 are slidably connected to the guide rods 19. The guide rods 19 restrict the drive plates 9 to slide only in a straight line, preventing them from shifting or shaking during movement. This not only ensures that the two drive plates 9 can synchronously and smoothly drive the clamping plate 11 to adjust the spacing.

[0028] As an optional technical solution of this utility model, a plurality of symmetrically arranged connecting grooves 20 are provided through one side of the locking plate 6, and the connecting plate 10 is slidably connected to the locking plate 6 through the connecting grooves 20. When installing the thermal imaging detector body 14, the connecting plate 10 can easily slide into the locking plate 6 along the connecting grooves 20 to quickly complete the positioning of the clamping plate 11; during use, the connecting grooves 20 limit the connecting plate 10 to prevent the clamping plate 11 from shifting when the UAV vibrates during flight or when the mechanical gripper moves, ensuring that the thermal imaging detector body 14 is reliably fixed.

[0029] As an optional technical solution of this utility model, the top of the frame 5 is fixedly connected with two symmetrically arranged splicing plates 21. The frame 5 is snapped into the drone body 1 through the two splicing plates 21. During the equipment installation stage, the splicing plates 21 can be accurately snapped into the corresponding slots of the drone body 1, so that the frame 5 is firmly installed at the bottom of the drone without complicated tools and operations, thus improving assembly efficiency. When the thermal imaging detector body 14 or the mechanical gripper malfunctions, the splicing plates 21 can be separated from the drone body 1, and the frame 5 and internal components can be removed as a whole for inspection and repair, avoiding excessive disassembly of the drone body 1.

[0030] As an optional technical solution of this utility model, a snap-fit ​​hole 22 is provided on one side of the clamping plate 11. The snap-fit ​​pin 13 is slidably connected to the clamping plate 11 through the snap-fit ​​hole 22. During use, the snap-fit ​​pin 13 and the snap-fit ​​hole 22 are tightly engaged to prevent the U-shaped frame 12 from loosening or falling off the clamping plate 11, ensuring that the thermal imaging detector body 14 remains stable during UAV flight and detection. In addition, this snap-fit ​​method facilitates the disassembly and replacement of the U-shaped frame 12. When it is necessary to upgrade or repair the thermal imaging detector body 14, the snap-fit ​​pin 13 can be easily pulled out to remove the U-shaped frame 12, improving the maintainability and flexibility of the equipment.

[0031] A high-altitude firefighting device for drones that uses thermal imaging detection-assisted mechanical grippers operates on the following principle:

[0032] 1) When the thermal imaging detector body 14 malfunctions, simply unscrew the bolts connecting the locking plate 6 to the drone body 1, and the frame 5 along with the thermal imaging detector body 14 can be pulled out from the groove 4 at the bottom of the drone body 1.

[0033] 2): The U-shaped frame 12 is engaged with the clamping plate 11 by the snap-fit ​​pin 13. The drive plate 9 is controlled to open and close by the first motor 8 and the bidirectional lead screw 7, which facilitates the quick separation of the thermal imaging detector body 14 for maintenance.

[0034] 3): Start the first motor 8, drive the bidirectional lead screw 7 to rotate, and the drive plate 9 moves along the bidirectional lead screw 7 under the guidance of the guide rod 19, adjust the distance between the two clamping plates 11, and adapt to the U-shaped frame 12 and the thermal imaging detector body 14 of different sizes.

[0035] In summary, this thermal imaging detection-assisted mechanical gripper for high-altitude firefighting using drones allows for convenient assembly and disassembly through components such as the frame 5 and locking plate 6. When the thermal imaging detector body 14 malfunctions, simply unscrewing the bolts connecting the locking plate 6 to the drone body 1 allows the frame 5, along with the thermal imaging detector body 14, to be pulled out of the groove 4 at the bottom of the drone body 1. The U-shaped frame 12 is engaged with the clamping plate 11 via the snap-fit ​​pin 13, and the drive plate 9 is controlled by the first motor 8 and the bidirectional lead screw 7 to facilitate quick separation of the thermal imaging detector body 14 for maintenance. This modular design avoids complete disassembly of the drone body 1, significantly shortening maintenance time, lowering the technical threshold for maintenance, reducing the risk of damage to other drone components caused by frequent and complex disassembly, ensuring the equipment's availability during fire rescue, and achieving flexible and accurate fire detection through the coordinated operation of multiple components. After the drone flies above the fire, it starts the first motor 8, which drives the bidirectional lead screw 7 to rotate. The drive plate 9 moves along the bidirectional lead screw 7 under the guidance of the guide rod 19, adjusting the distance between the two clamping plates 11 to accommodate different sized U-shaped frames 12 and the thermal imaging detector body 14. Next, the second motor 15 is started, and its output spur gear 16 meshes with the arc-shaped rack 17 on the back of the thermal imaging detector body 14, driving the thermal imaging detector body 14 to rotate within the U-shaped frame 12 and adjust the detection angle. The connecting slot 20 on the locking plate 6 cooperates with the connecting plate 10 to ensure the stability of the clamping structure; the splicing plate 21 at the top of the frame 5 engages with the drone body 1, ensuring overall connection reliability. This design allows for rapid adjustment of the position and angle of the thermal imaging detector body 14 according to the actual fire situation, accurately capturing thermal radiation signals, providing accurate data support for firefighting decisions, and improving firefighting efficiency and safety.
