Description

Technical Field

[0001] This invention belongs to the field of fire protection equipment technology, and in particular relates to a device for laying a fire control blanket for automobiles. Background Technology

[0002] In recent years, with the increasing number of new energy vehicles on the road, fires in their power batteries often release large amounts of toxic gases, causing violent combustion that quickly spreads to other vehicles, and traditional firefighting methods are often ineffective in extinguishing them. Therefore, it is urgent to prevent the fire from spreading through isolation measures.

[0003] Currently, the deployment of fire blankets in existing technologies largely relies on manual operation, which presents the following prominent problems: Deploying a fire blanket requires a large open space and generally necessitates the coordinated operation of multiple people, making it particularly difficult in confined spaces and subject to limitations imposed by the height and build of the operators; if there is insufficient space around the burning vehicle, the fire blanket may be deployed too far from the vehicle, hindering its rapid deployment and severely impacting fire control. Although some solutions utilize robots equipped with deployment systems for automated movement, their deployment structures typically only allow for extension in a single direction, making it difficult to flexibly adjust the width and height of the fire blanket according to the actual size and parking posture of the burning vehicle, resulting in poor adaptability.

[0004] In summary, existing automotive fire blanket installation devices generally suffer from problems such as fixed installation locations, inflexible movement, difficulty in adapting to different vehicle models and parking scenarios, and limited installation actions. There is an urgent need for a new type of fire blanket installation device that can be moved flexibly, adjusted in multiple dimensions, and is highly adaptable. Summary of the Invention

[0005] The purpose of this invention is to solve the aforementioned technical problems existing in the prior art, and to provide an automotive fire blanket laying device. This device achieves flexible overall movement by incorporating a walking mechanism that can travel along the ground. A first telescopic mechanism extends the lifting base out of the walking mechanism, and the telescopic base extends to support the ground, ensuring stable installation. A horizontal moving mechanism fine-tunes the lifting mechanism according to the location of the burning vehicle to achieve precise alignment. The lifting mechanism drives the fire blanket to rise and fall to adjust the laying height, and a second telescopic mechanism extends the end of the fire blanket outward to complete the laying. This allows for flexible adjustment of the fire blanket in multiple directions, including horizontal extension, vertical height, and lateral alignment. It can adaptively adjust the laying posture of the fire blanket according to the actual parking position, vehicle height, and vehicle width of the burning vehicle, effectively solving the technical problems of fixed laying device positions and difficulty in flexibly adapting to different vehicle models and parking scenarios in the prior art.

[0018] This invention, by setting up a walking mechanism that travels along the ground, allows the entire laying device to move autonomously to the side of the burning vehicle according to the location of the fire, without being limited by fixed parking spaces or fixed installation locations. It can be applied to various scenarios such as underground garages and open-air parking lots, effectively solving the defect of existing fixed laying devices that cannot cover multiple parking spaces.

[0019] This invention utilizes a first telescopic mechanism to extend the lifting base out of the traveling mechanism, and the telescopic base of the lifting base extends out to support the ground, achieving overall stability of the device.

[0022] This invention achieves fully automated operation of fire blanket laying through the coordinated cooperation of various telescopic, lifting, and horizontal movement mechanisms. It eliminates the need for firefighters to manually lay the blankets in close proximity to burning vehicles, effectively ensuring the safety of operators. It is especially suitable for special areas where personnel should not enter, such as areas with high radiation or high confidentiality. Attached Figure Description

Detailed Implementation

[0034] like Figures 1 to 9 As shown, this invention provides a vehicle fire control blanket laying device, comprising a walking mechanism 1 that travels along the ground, a base assembly, a first telescopic mechanism 3, a lifting mechanism 6, a horizontal moving mechanism 5, and a second telescopic mechanism 8.

[0035] The walking mechanism 1 in this application can be a vehicle such as a car or a mobile vehicle that can move autonomously along the ground, used to drive the entire laying device to the vicinity of the burning vehicle.

[0036] The base assembly is mounted on the traveling mechanism 1. The base assembly includes a fixed base 2 and a lifting base 21. The fixed base 2 is fixedly mounted on the traveling mechanism 1, while the lifting base 21 is height-adjustable. A first telescopic mechanism 3 is installed between the fixed base 2 and the lifting base 21 to adjust the distance between them, control the lifting base 21 to move closer to or further away from the traveling mechanism 1, and push the lifting base 21 outwards to provide working space. Two sets of the first telescopic mechanism 3 are correspondingly provided with the base assembly. Each set of the first telescopic mechanism 3 is connected to the lifting base 21 by a connecting column 26. A mounting plate 27 is provided between the two connecting columns 26, and the mounting plate 27 is used to mount the horizontal moving mechanism 5. The lifting base 21 includes a mounting base 22 and a telescopic base 23. The mounting base 22 is provided with a cavity 24, and an adjusting cylinder 25 is installed in the cavity 24. The output end of the adjusting cylinder 25 is connected to the telescopic base 23 to drive the telescopic base 23 to achieve lifting action. After the telescopic base 23 extends downward, it can abut against the ground to form support, thereby improving the operational stability of the device.

[0037] The first telescopic mechanism 3 adopts a multi-stage telescopic structure, specifically including a primary drive shaft 31 and a primary telescopic component 32. The primary drive shaft 31 is connected to the drive source 4, and the primary telescopic component 32 is connected to the primary drive shaft 31. The drive source 4 drives the primary drive shaft 31 to rotate, thereby causing the primary telescopic component 32 to move axially along the primary drive shaft 31 to achieve primary telescopic movement. The first telescopic mechanism 3 also includes a secondary drive shaft 33 and a secondary telescopic component 34. The secondary drive shaft 33 is connected to the primary drive shaft 31 and can rotate synchronously with the primary drive shaft 31. The secondary telescopic component 34 is connected to the secondary drive shaft 33, and the secondary drive shaft 33 causes the secondary telescopic component 34 to move axially along the secondary drive shaft 33 to achieve secondary telescopic movement. The first telescopic mechanism 3 also includes a third-stage drive shaft 35 and a third-stage telescopic member 36. The third-stage drive shaft 35 is connected to the second-stage drive shaft 33 and can rotate synchronously with the second-stage drive shaft 33. The third-stage telescopic member 36 is connected to the third-stage drive shaft 35 in a transmission connection. The third-stage drive shaft 35 drives the third-stage telescopic member 36 to move axially along the third-stage drive shaft 35 to achieve three-stage telescopic movement.

[0038] The primary drive shaft 31 and the primary telescopic component 32, the secondary drive shaft 33 and the secondary telescopic component 34, and the tertiary drive shaft 35 and the tertiary telescopic component 36 are all connected by threaded transmission. The primary drive shaft 31, the secondary drive shaft 33 and the tertiary drive shaft 35, as well as the primary telescopic component 32, the secondary telescopic component 34 and the tertiary telescopic component 36 are all provided with mutually cooperating grooves and protrusions. The grooves and protrusions are used to limit the circumferential relative displacement and prevent circumferential relative sliding between the primary drive shaft 31 and the secondary drive shaft 33, between the secondary drive shaft 33 and the tertiary drive shaft 35, between the primary telescopic component 32 and the secondary telescopic component 34, and between the secondary telescopic component 34 and the tertiary telescopic component 36.

[0039] In this application, the drive source 4 includes a drive motor 41, a driving wheel 42, and a driven wheel 43. The driving wheel 42 is fixedly connected to the output end of the drive motor 41, and the driven wheel 43 is fixedly connected to the primary drive shaft 31. The driving wheel 42 and the driven wheel 43 are connected by a belt drive. Each of the two sets of first telescopic mechanisms 3 has a transmission wheel 44 on its primary drive shaft 31. The two transmission wheels 44 are connected by a transmission belt to achieve synchronous telescopic movement of the two sets of first telescopic mechanisms 3.

[0040] The horizontal moving mechanism 5 is mounted on the mounting plate 27 and is used to horizontally move the lifting mechanism 6. It finely adjusts the horizontal position of the two sets of lifting mechanisms 6 according to the actual parking position of the burning vehicle, ensuring precise alignment of the fire blanket with the laying position. The horizontal moving mechanism 5 includes a mounting base 51, an adjusting motor 52, and a first screw 53. The adjusting motor 52 is mounted on the mounting base 51, which is provided with a first bearing seat 54. The first screw 53 is rotatably mounted on the first bearing seat 54, and one end of the first screw 53 is connected to the adjusting motor 52 via a first coupling 55. Two first moving seats 56 are provided on the first screw 53, and each first moving seat 56 is equipped with a set of lifting mechanisms 6.

[0041] The lifting mechanism 6 is used to drive the fire control blanket to rise and fall in a direction perpendicular to the ground. The lifting mechanism 6 includes a movable plate 61, a lifting motor 62, and a second screw 63. The movable plate 61 is fixedly connected to the first movable seat 56. The lifting motor 62 is mounted on the movable plate 61. The movable plate 61 is provided with a second bearing seat 64. The second screw 63 is rotatably mounted on the second bearing seat 64, and one end of the second screw 63 is connected to the lifting motor 62 via a second coupling. A second movable seat 65 is provided on the second screw 63, and a lifting seat 66 is fixedly mounted on the second movable seat 65. The lifting seat 66 is used to install the fire control blanket. Both the mounting seat 51 and the movable plate 61 are provided with slide rails 7. The movable plate 61 and the lifting seat 66 are provided with sliders 71 corresponding to the positions of the slide rails 7. The slide rails 7 and the sliders 71 cooperate with each other to provide guidance for the movement of the movable plate 61 and the lifting seat 66.

[0042] In this invention, the lifting seat 66 is used to install the fire control blanket and the second telescopic mechanism 8. Specifically, a fixed seat can be installed on the lifting seat 66, and a rotating shaft is provided between the two fixed seats. The fire control blanket is installed on the rotating shaft.

[0043] The second telescopic mechanism 8 is installed on the lifting seat 66 of the lifting mechanism 6. Its height is controlled by the lifting mechanism 6. The output end of the second telescopic mechanism 8 is connected to the end of the fire blanket, which is used to drive the fire blanket to unfold and lay on the burning vehicle. The second telescopic mechanism 8 includes a telescopic cylinder 81, a connecting piece 82, a guide seat 83, and a telescopic assembly 9. The output end of the telescopic cylinder 81 passes through the guide seat 83 and is connected to the connecting piece 82. The first hinge point 95 of the telescopic assembly 9 is hinged to the guide seat 83, and the second hinge point 96 is hinged to the connecting piece 82. The output end of the telescopic assembly 9 is connected to the fire blanket. When the telescopic cylinder 81 drives the connecting piece 82 to move, the connecting piece 82 drives the telescopic assembly 9 to complete the telescopic action, so as to realize the laying and rolling of the fire blanket.

[0044] The telescopic assembly 9 includes a first hinge rod 91, a telescopic rod 92, a second hinge rod 93, and a connecting seat 94. The guide seat 83 is equipped with a hinge shaft 84. One end of the first hinge rod 91 is hinged to the hinge shaft 84 via a first hinge point 95, and the other end is hinged to the telescopic rod 92 via a third hinge point 97. Multiple sets of telescopic rods 92 are provided, with adjacent telescopic rods 92 hinged to each other via a second hinge point 96. One end of the second hinge rod 93 is hinged to the telescopic rod 92 via a third hinge point 97, and the other end is hinged to the connecting seat 94, which is connected to the fire blanket. The ends of the two second hinge rods 93 connected to the connecting seat 94 are each provided with teeth 98. The two teeth 98 mesh with each other to ensure that the telescopic structures on both sides unfold synchronously, improving the stability of the fire blanket installation.

[0045] The workflow of this invention is as follows:

[0046] First, the walking mechanism 1 drives the entire device to move autonomously along the ground to the preset working position next to the burning vehicle.

[0047] The first telescopic mechanism 3 is activated, and the drive source 4 drives the first-stage drive shaft 31, the second-stage drive shaft 33, and the third-stage drive shaft 35 to rotate synchronously. This drives the first-stage telescopic component 32, the second-stage telescopic component 34, and the third-stage telescopic component 36 to extend in sequence, pushing the lifting base 21 horizontally outward to the outside of the walking mechanism 1. After the lifting base 21 moves to the set position, the adjusting cylinder 25 in the cavity 24 of the mounting base 22 is activated, driving the telescopic base 23 to extend downward until the bottom of the telescopic base 23 abuts against the ground to form a stable support, ensuring the structural stability of subsequent laying operations.

[0048] The adjusting motor 52 of the horizontal moving mechanism 5 is started, and the first screw 53 is driven to rotate through the first coupling 55, which drives the two first moving seats 56 and the corresponding lifting mechanism 6 to move horizontally synchronously. The horizontal position of the lifting mechanism 6 is finely adjusted according to the actual parking position of the burning vehicle, so that the preset laying range of the fire control blanket corresponds precisely to the vehicle position.

[0049] The lifting motor 62 of the lifting mechanism 6 starts, drives the second screw 63 to rotate through the second coupling, drives the second moving seat 65 to descend vertically, and then drives the lifting seat 66 and the fire control blanket to descend synchronously until the fire control blanket is adjusted to the appropriate laying height above the burning vehicle.

[0050] The telescopic cylinder 81 of the second telescopic mechanism 8 is activated, pushing the connecting piece 82 to move horizontally along the guide seat 83. The connecting piece 82 drives the telescopic assembly 9 to gradually unfold. The telescopic assembly 9 is linked by the first hinge rod 91, multiple sets of telescopic rods 92 and the second hinge rod 93. With the synchronous action of the meshing teeth 98 at the ends of the two second hinge rods 93, the connecting seat 94 at the end drives the end of the fire blanket to extend outward smoothly. Finally, the fire blanket is completely laid and covered on the burning vehicle to achieve fire isolation and control.

[0051] After the fire blanket is fully laid and covers the burning vehicle, the lifting mechanism 6 can be restarted. The lifting motor 62 drives the second screw 63 to rotate, causing the second moving seat 65, the lifting seat 66 and the fire blanket to drop slightly as a whole, so that the two ends of the fire blanket are in contact with the ground, forming a closed isolation around the vehicle, enhancing the oxygen isolation and fire control effect, and inhibiting the spread of toxic smoke to the surrounding area.

[0052] After the fire is extinguished, the telescopic cylinder 81 retracts in the reverse direction, causing the connecting piece 82 to reset, which in turn causes the telescopic assembly 9 to retract, thus retracting the fire blanket. Subsequently, the lifting motor 62 drives in the reverse direction, causing the second moving seat 65, the lifting seat 66, and the fire blanket to rise and reset. The adjusting cylinder 25 reverses its movement, causing the telescopic base 23 to retract upward into the cavity 24 of the mounting base 22. The first telescopic mechanism 3 reverses its movement, causing the lifting base 21 to retract above the traveling mechanism 1. Finally, the traveling mechanism 1 moves the entire device away from the fire scene, completing all operations.

[0053] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
