Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, and in particular to a vehicle-mounted fire-fighting drone platform with rapid deployment and retrieval capabilities. Background Technology

[0002] With the increasing demand for efficient and precise operations in the fire and rescue field, drones, with their advantages of wide field of vision and rapid response, are playing an increasingly crucial role in tasks such as fire reconnaissance, disaster assessment, and delivery of firefighting equipment. To achieve rapid deployment and mobile response of firefighting drones, mounting them on fire trucks has become an important application method, and vehicle-mounted firefighting drone platforms are the core devices ensuring the safe transport of drones and efficient on-site operations.

[0003] Currently, most vehicle-mounted firefighting drone platforms use a box-type structure for storage and protection of the drones. However, there are still many shortcomings in practical applications: the opening and closing of the box doors and the process of moving the drone out of the box and lowering it to the ground in existing box-type platforms have a low degree of automation and coordination. They often require a lot of manual intervention or rely on step-by-step mechanical operations, resulting in long deployment times for drones and making it difficult to meet the core requirement of "rapid response" at fire scenes. Some platforms use a structure where the drone moves upwards to detach from the box. Firefighters need to climb to the top of the box to perform operations such as connecting fire hoses. However, the operating space at the top of the box is cramped, and there are safety hazards such as falls for personnel working at height. Moreover, the operating posture is limited, which is not only inefficient, but also easily affects the reliability of the connection between firefighting equipment and drones due to insufficient operational stability. Existing vehicle-mounted firefighting drone platforms cannot fully meet the needs of efficient and safe operation at fire rescue scenes and need to be optimized and improved. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a vehicle-mounted firefighting drone platform with rapid deployment and retrieval capabilities.

A positioning plate 13 is fixed at the bottom of the box body 11. The positioning plate 13 is equipped with a positioning groove 14 that cooperates with the buffer component 82. When the fixed frame 7 is located inside the storage box 1, the two buffer wheels 86 on the buffer component 82 can be located on both sides of the positioning plate 13. The two sides of the positioning plate 13 are symmetrical slopes. The connecting block 83 on the buffer component 82 can be located in the positioning groove 14, which can position the fixed frame 7 and prevent the fixed frame 7 from moving inside the storage box 1.

[0025] The control mechanism 3 includes a telescopic component 31, which is provided with a mounting plate 32 and is fixedly installed in the housing 11. The output shaft of the telescopic component 31 is connected to a connecting plate 33, which is connected to the door 12.

[0026] The translation component 5 includes a second guide rail component 52, a drive component, and a moving component 58. The guide rail of the second guide rail component 52 is provided with a mounting plate 51 fixedly connected to the upper part of the housing 11. The slider of the second guide rail component 52 is provided with mounting frame plates 54. Two mounting frame plates 54 are provided and symmetrically located on both sides of the mounting frame plate 4. A connecting plate 53 connects the two mounting frame plates 54. The mounting frame plate 4 includes two positioning frame plates 41, which are respectively installed symmetrically below the mounting frame plate 4. On both sides, a guide rail assembly 42 is provided below each of the two mounting frame plates 54. The guide rail of the guide rail assembly 42 is mounted on the mounting frame plate 54.

[0027] The driving component includes a telescopic member 55, which is provided with a mounting plate 56 and is fixedly installed in the housing 11. The output shaft of the telescopic member 55 is connected to a connecting plate 57, which is connected to one of the mounting frame plates 54. The telescopic member 55, the mounting plate 56, and the connecting plate 57 form a translation driving structure, providing stable power for the first stage of movement of the translation component 5.

[0028] The moving component 58 includes synchronous wheels 581 rotatably mounted at both ends of another mounting frame plate 54. A synchronous belt 582 is fitted onto the two synchronous wheels 581. A clamping plate 44 is located below the synchronous belt 582 and is connected to a connecting plate 43. The connecting plate 43 is fixedly connected to an adjacent positioning frame plate 41. A connecting plate 583 is located above the synchronous belt 582. A positioning plate 585 is connected to the connecting plate 583. Clamping plates 584 are connected to both the connecting plate 583 and the positioning plate 585. The positioning plate 585 has a locking groove and is fixedly connected to the housing frame 15 through the locking groove. 43 and clamping plate 44 form a clamp below the synchronous belt 582, while connecting plate 3 583, positioning plate 2 585 and clamping plate 2 584 form a clamp above the synchronous belt 582. Clamping plate 1 44 and clamping plate 2 584 are provided with meshing grooves that engage with the teeth on the inner side of the synchronous belt 582. Through the meshing transmission design of synchronous pulley 581, synchronous belt 582 and clamping plate, the power is ensured to not slip. Positioning plate 2 585 fixes one end of synchronous belt 582, so that synchronous belt 582 rotates relative to the mounting frame plate 54 when it moves, realizing the second stage of autonomous transmission. The superposition of the two stages of movement improves the distance and speed of the UAV.

[0029] The lifting mechanism 6 includes a drive component 61, a mounting plate 68, and a rotating shaft 64. The drive component 61 is mounted on the mounting plate 68, and a fixed frame plate 62 is fixedly connected to the mounting plate 68. The fixed frame plate 62 is fixed below the mounting frame plate 4. The drive component 61 is mounted on the fixed frame plate 62. The rotating shaft 64 is provided with multiple fixed seats 69. The rotating shaft 64 is rotatably mounted below the mounting frame plate 4 through the multiple fixed seats 69. The output shaft of the drive component 61 is provided with a transmission component 63, which is connected to the rotating shaft 64 through the transmission component 63. A fixed sleeve 65 is sleeved on the rotating shaft 64. A lifting belt 66 is wound on the fixed sleeve 65. One end of the lifting belt 66 is fixedly connected to the fixed sleeve 65, and the other end of the lifting belt 66 is connected to the fixed frame 7 through a connecting hole 67.

[0030] The fixed frame 7 includes a support base 71, with a connecting stand 74 in the middle. The support base 71 has two locking parts 72 for pressing the drone legs, and limiting plates 73 for limiting the drone position on both sides. The connecting stand 74 has a connecting part 75 above it that connects to the connecting hole 67 on the lifting belt 66. The limiting plate 73 can quickly position the drone, reducing the alignment time when placing the drone. The locking part 72 is a quick-locking clamp in the prior art, which enables the drone legs to be quickly fixed and unlocked without the need for tools, greatly shortening the drone assembly and disassembly time. The connecting part 75 ensures that the fixed frame 7 is reliably connected to the lifting belt 66, ensuring that the fixed frame 7 does not fall off during the lifting process. The connecting part 75 can be U-shaped in use, and its end is fixedly connected to the connecting stand 74 by bolts.

[0031] The support assembly 8 includes a buffer component 82 mounted on the support base frame 71 via a mounting plate 3 81, and a connecting rod 84 with connecting frame plates 85 at both ends. A buffer wheel 86 is rotatably mounted inside the connecting frame plate 85. A connecting block 83 is connected below the buffer component 82. A connecting end is provided in the middle of the connecting rod 84 and is rotatably connected to the connecting block 83 through the connecting end. A fixing block 87 is provided on one of the connecting frame plates 85. An arc-shaped guide rod 88 is provided on the fixing block 87. A spring 89 is sleeved on the guide rod 88. A sliding plate 810 is provided on the buffer component 82. A sliding groove is provided on the sliding plate 810. A moving block 811 is slidably mounted in the sliding groove.

[0032] The buffer component 82 includes a housing 821 and a buffer rod 822. One end of the buffer rod 822 is located inside the housing 821. A pressing part 823 is provided on the end of the buffer rod 822 located inside the housing 821. A spring 824 is provided inside the housing 821. The other end of the buffer rod 822 is connected to a connecting block 83. The guide rod 88 rotates concentrically with the connecting rod 84 and the connecting block 83. A sliding plate 810 is provided on the housing 821.

[0033] In its initial state, the drone is fixed to the vehicle platform by the fixed frame 7. Firefighters place the drone on the support frame 71, quickly position the drone using the limiting plate 73, and then operate the two locking pieces 72 to press and fix the drone legs to the support frame 71. At this time, the connecting block 83 of the support component 8 is inserted into the positioning groove 14 of the positioning plate 13, limiting the shaking of the fixed frame 7, and the box door 12 is closed. The translation component 5 and the lifting mechanism 6 are both in the storage position. The overall structure is compact and suitable for the transportation needs of fire trucks.

[0034] When the fire truck arrives at the fire scene and a drone needs to be deployed, the control mechanism 3 is activated, the telescopic component 31 is powered on and its output shaft extends outward, and pushes the door 12 around the hinge point with the body 11 through the connecting plate 33 until the door 12 rotates to a position greater than horizontal to avoid the door 12 blocking the drone's movement path. The telescopic component 31 then stops working, and the door 12 remains open. The whole process does not require manual opening of the door, which can save operation time. After the box door 12 is opened, the translation component 5 is activated to realize the two-stage removal of the drone from the box 11; The first stage of movement: When the telescopic component 2 55 is powered on, its output shaft extends outward. It pushes the mounting frame 54 connected to it through the connecting plate 2 57. The mounting frame 54 moves outward along the guide rail of the guide rail assembly 2 52. At the same time, it drives another mounting frame 54 to move synchronously through the connecting plate 2 53. Then it can drive the moving component 58 to move together. When the moving component 58 moves, it drives the mounting frame 4, the lifting mechanism 6, and the fixed frame 7 to move outward as a whole through the connecting plate 1 43 and the clamping plate 1 44. The first stage of movement ends when the output shaft of the telescopic component 2 55 extends to the specified length. During this process, since the positioning plate 2 585 is fixed to the box frame 15 through the locking groove, the part of the synchronous belt 582 held by the clamping plate 2 584 above remains stationary and its relative position to the box 11 remains unchanged. The part of the synchronous belt 582 held by the clamping plate 1 44 and the connecting plate 1 43 below moves outward synchronously with the movement of the mounting frame 54, laying the foundation for the autonomous movement in the second stage. Second stage of movement: During the first stage of movement, the moving component 58 moves synchronously. Since the positioning plate 585 is fixed to the housing frame 15 via the locking groove, the part of the synchronous belt 582 held by the clamping plate 584 remains stationary. When the mounting frame plate 54 drives the synchronous wheel 581 to move outward, the synchronous wheel 581 drives the synchronous belt 582 to rotate around the synchronous wheel 581. The part of the synchronous belt 582 held by the clamping plate 44 moves outward with the rotation of the synchronous belt 582. The connecting plate 43 pulls the positioning frame plate 41 connected to it to move further outward, thus completing the positioning... The frame plate 41 can drive the connected mounting plate 4 to move outward as a whole, thereby realizing the second stage of movement. The mounting plate 4 drives the drone to be completely moved out of the box 11, and the translation component 5 stops working. The two-stage movement design greatly improves the drone's removal speed and movement distance, ensuring that the drone is completely free from the box 11's obstruction, which is convenient for subsequent lowering and operation. In this process, the meshing grooves on the clamping plate 1 44 and clamping plate 2 584 are tightly engaged with the inner teeth of the synchronous belt 582, ensuring that the rotation of the synchronous belt 582 can be accurately converted into the translational force of the mounting plate 4. After the drone is completely removed, the lifting mechanism 6 is activated to lower the drone to the ground. The drive component 61 is activated, and its output shaft drives the rotating shaft 64 to rotate through the transmission component 63. The rotating shaft 64 drives the fixed sleeve 65 to rotate synchronously. The lifting belt 66 wound on the fixed sleeve 65 is gradually released, and the fixed frame 7 is slowly lowered under the action of gravity as the lifting belt 66 is released. After the drone is completely removed, the support component 8 is in its initial position. Since one end of the guide rod 88 is located on the fixed block 87 of the connecting frame plate 85, and the other end is connected to the slide plate 810 of the buffer component 82 through the moving block 811, and the rotation centers of the guide rod 88, the connecting rod 84, and the connecting block 83 are concentric, the spring 89 on the guide rod 88 will apply a torque about the rotation center to the connecting rod 84, so that the overall initial state of the connecting rod 84 is maintained in an inclined posture, so that the two buffer wheels 86 at both ends of the connecting rod 84 have a significant height difference. During the descent, the support component 8 provides dual cushioning. First, the buffer wheel 86 disengages from the positioning groove 14 and contacts the ground. As the fixed frame 7 continues to descend, the connecting rod 84 rotates around the connecting block 83, and the guide rod 88 slides along the guide hole of the moving block 811. The second spring 89 is compressed, absorbing the first stage of impact force. Subsequently, the connecting rod 84 rotates to a near-horizontal position, and the supporting base 71 applies pressure to the buffer component 82 through the mounting plate 81. The buffer rod 822 retracts into the outer shell 821, and the squeezing part 823 compresses the first spring 824, absorbing the second stage of impact force, until the supporting base 71 smoothly contacts the ground. The drive component 61 stops working, and the descent of the UAV is completed, ensuring that the fixed frame 7 lands smoothly and the UAV is free from vibration damage, greatly improving the safety of the descent.

[0035] The drones compatible with this platform can be agricultural drones. Agricultural drones can be easily modified to perform firefighting operations. The original water tank of the agricultural drone can be removed, while retaining its main body, flight control system and outrigger structure. Then, fire hoses can be tied to the drone body. Utilizing the original payload capacity and flight maneuverability of the agricultural drone, the fire hoses can be driven to spray water and extinguish fires at the scene.
