Description

Technical Field

[0001] This utility model belongs to the field of logistics and transportation technology and relates to an automatic fire extinguishing device. Background Technology

[0002] Shipping is an important logistics method for large cargoes. For vehicles like automobiles, current technology typically involves docking them in the ship's cargo hold and securing them to the ground using specific methods (such as straps and chains). However, during actual transport, various factors, such as the ship's turbulence causing impacts to the vehicle's (especially new energy vehicles) batteries, can potentially lead to fires in the cargo hold. To effectively reduce property damage and ensure the safety of personnel, current technology generally equips vehicles with specialized fire extinguishing systems.

[0003] For example, Chinese Patent (Application Publication No.: CN119857228A) discloses an automatic fire extinguishing device for new energy vehicle batteries after thermal runaway. It includes a base, a control box, a fire blanket body, a release assembly, and a fire detection probe. The base has a frame-like structure and is fixed to a predetermined position on the vehicle, with a fixing strip on its top surface. The fire blanket body is rectangular, comprising a base fabric layer, a coating layer, and a heat-insulating filling layer, with a positioning strip on the top surface and weighted blocks on both sides. The release assembly includes a fixing seat, a splicing seat, an electromagnet, a fusion strip, and a connecting block. The electromagnet magnetically attracts the weighted blocks to house the fire blanket. The fire detection probe includes a spectral sensor, a smoke sensor, and an infrared temperature sensor for real-time fire monitoring. In the event of a fire, the device can receive a detection signal through the control box and cut off the power to the electromagnet, or the fusion strip melts at high temperature to actively cut off the power, causing the weighted blocks to fall and pull the fire blanket body to fully unfold and cover the burning area, suppressing the fire by blocking oxygen.

[0004] Considering the specific circumstances, the number of vehicles parked in the ship's hold is large and they are parked in multiple rows or columns in an orderly manner. If each car were equipped with a fire extinguishing device, the size of the fire extinguishing device itself would inevitably affect the number of vehicles that the ship's hold can accommodate. Therefore, although the existing technology still requires multiple fire extinguishing devices, each fire extinguishing device is set up for a row or column of vehicles, thereby saving space to the greatest extent.

[0005] However, the device has significant drawbacks in actual use. Specifically, due to the spacing between vehicles in the same row or column, a considerable amount of space remains inside the fire blanket after it is deployed. Because there is sufficient oxygen, the fire inside the fire blanket is not only not controlled but worsens, causing several vehicles in the same row or column to catch fire at the same time. In severe cases, it may even ignite the fire blanket and spread to the entire cabin. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an automatic fire extinguishing device. The technical problem to be solved by this invention is: how to accurately and effectively suppress fires.

[0007] The objective of this utility model can be achieved through the following technical solution: An automatic fire extinguishing device includes a frame arranged horizontally and containing a fire blanket inside, and the frame is provided with a blanket throwing mechanism for throwing the fire blanket down. The automatic fire extinguishing device further includes at least two parallel tracks, the frame is located below each track, a connecting rod perpendicular to each track is fixed on the frame, at least two sets of roller assemblies are fixed on the connecting rod, each set of roller assemblies is slidably connected to each track and positions the frame vertically below each track, and a number of motors corresponding to the number of roller assemblies are fixed on the frame, the shaft of each motor is connected to the corresponding roller assembly and can drive the frame to slide along the length direction of each track.

[0008] The working principle of this automatic fire extinguishing device is as follows: A fire blanket is used to cover the fire area, isolating it from the air to achieve a flame-retardant effect. The difference between this application and existing technologies lies in the use of a track-type structure to support the frame containing the fire blanket. The top of the cabin serves as the load-bearing point, and each track is fixed to the top of the cabin to ensure its installation stability. Specifically, the frame is located below the slide rails. Connecting rods are additionally installed on the frame, and at least two sets of roller assemblies are mounted on these rods. A motor mounted on the frame drives the roller assemblies. During actual operation, the driven roller assemblies move the connecting rods, allowing the entire frame to slide along the slide rails, thereby achieving fire suppression of the frame and its contents. Compared to existing technologies, this application allows for adaptive positioning adjustments to the fire blanket. The arrangement of the aforementioned scheme further optimizes the space within the ship's cabin, avoiding limitations on the number of vehicles that can be parked due to an excessive number of frame structures. Furthermore, through the coordination of roller assemblies and tracks, in the event of a fire, the fire blanket can be deployed precisely to the point of ignition by adaptively adjusting the frame position. This prevents gaps between vehicles from creating a large amount of air within the fire blanket, which could provide favorable combustion conditions for the fire. This allows for more effective and rapid fire control, eliminating the regional fire suppression methods of existing technologies and effectively preventing the spread to surrounding vehicles and even the entire ship's cabin, thus ensuring a higher safety factor during transportation.

[0009] In the aforementioned automatic fire extinguishing device, each set of roller assemblies includes two U-shaped mounting plates and two main rollers. The two mounting plates are fixed to the outer walls of the connecting rod on both sides and are arranged opposite each other. The two main rollers are rotatably connected between the two mounting plates and their axis is parallel to the center line of the connecting rod. The outer walls of the two main rollers abut against the corresponding upper side of the track. The rotating shaft of the motor is fixedly connected to the rotating shaft of one of the main rollers. As a specific solution, two mounting plates are used as a connecting structure to connect the two main rollers and the connecting rod. Ensuring a secure connection between the main rollers, the two main rollers of the same group abut against the upper side of their respective slide rails. With the cooperation of the two roller assemblies and the two slide rails, the frame is vertically limited. Furthermore, the rotation of the main rollers causes the frame to slide along the length of the two slide rails, adjusting the position of the fire blanket. A motor drives one of the main rollers to rotate, causing the other main roller to rotate as well, thus controlling the frame's movement and adjusting its position.

[0010] In the aforementioned automatic fire extinguishing device, all tracks are I-beam rails, and each roller assembly includes two side rollers. These two side rollers are rotatably connected between two U-shaped plates and are located directly below the two main rollers. The axis of each side roller is vertically aligned, with the outer wall of one side roller abutting against one side of the corresponding track's outer wall, and the outer wall of the other side roller abutting against the other side of the corresponding track's outer wall. As a further optimization, each roller assembly, through the cooperation of the two side rollers and the corresponding track, achieves horizontal front-back direction limitation when the frame moves horizontally left and right, or horizontal left-right direction limitation when the frame's sliding direction is horizontal front-back. This ensures the overall stability of the frame and the connection between the tracks, effectively preventing the frame from sagging during movement and causing damage to the paint of the transport vehicle.

[0011] In the aforementioned automatic fire extinguishing device, a mounting bracket is provided on one side of each of the two mounting plates. The mounting bracket is U-shaped and connected and fixed to the two mounting plates. The motor is fixed to the mounting bracket. This arrangement provides a stable mounting platform for the motor, ensuring stable installation and smooth rotation of the motor's drive on one of the main rollers.

[0012] In the aforementioned automatic fire extinguishing device, the frame includes two long rods and two short rods fixed to the ends of the two long rods. The two long rods are arranged laterally and perpendicular to the two tracks. The two short rods are located at the ends of the two long rods and parallel to the two tracks. The connecting rod is located between the two long rods and its two ends are fixedly connected to the two short rods. Each long rod is provided with two sets of roller assemblies, and the two sets of roller assemblies located on the same long rod are slidably connected to the two tracks. This setup ensures reliable connection between the connecting rod and the frame. Based on this structure, roller assemblies that cooperate with the two tracks are also arranged on the two long rods of the frame, further improving the frame's vertical stability while ensuring smooth lateral sliding. It's worth noting that the roller assemblies on the two long rods do not require motors; that is, only the roller assemblies mounted on the connecting rods need motors to drive the frame. Alternatively, manufacturers can equip all roller assemblies with motors.

[0013] Compared with existing technologies, this automatic fire extinguishing device has the following advantages: it uses a sliding adjustment method to drive the frame on at least two tracks, so that the frame can adjust the placement of the fire blanket according to the fire point, and accurately and effectively suppress the fire at the fire point while optimizing space to the greatest extent.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1 and Figure 4As shown, this automatic fire extinguishing device includes a frame 1 containing a fire blanket and two tracks 2. The two tracks 2 are arranged side by side in a horizontal direction. During specific assembly, the two tracks 2 can be fixed to the top bulkhead of the cabin by screws by mounting vertically arranged fixing plates at both ends, so that the two tracks 2 are suspended and remain in position.

[0021] Secondly, the frame 1 specifically includes two long rods 13 and two short rods 14. The two long rods 13 are arranged in the horizontal longitudinal direction, and the two short rods 14 are arranged in the horizontal transverse direction. That is, the two long rods 13 and the two tracks 2 are perpendicular to each other, and the two short rods 14 and the two tracks 2 are parallel to each other. The two short rods 14 are located at both ends of the two long rods 13. The two long rods 13 are fixed together by the two short rods 14, thus forming a rectangular frame 1. Regarding how to assemble the fire blanket inside the frame 1 and how the frame 1 can throw down the fire blanket during fire extinguishing operations, existing technologies can be used. For example, an automatic fire extinguishing device for automatic sensing of thermal runaway of new energy vehicle battery disclosed in Chinese Patent (Application Publication No.: CN119857228A) can be referred to. This embodiment will not elaborate on this part of the structure.

[0022] Combination Figure 2 A connecting rod 11 is provided within the frame 1. The two ends of the connecting rod 11 are fixedly connected to two short rods 14 and parallel to two long rods 13. The connecting rod 11 is specifically located below the two tracks 2. Two sets of roller assemblies 3 are provided on the connecting rod 11 corresponding to the two tracks 2, as detailed below. Figure 3 As shown, each roller assembly 3 includes two U-shaped mounting plates 31, two main rollers 32, and two side rollers 33. For the assembly of the two mounting plates 31, the two mounting plates 31 are specifically arranged on the two opposite outer walls of the connecting rod 11 and locked with screws, so that one side of the two mounting plates 31 is facing each other. Two main hinge seats are fixed between the two mounting plates 31 with screws. One main hinge seat is located on one side of the two mounting plates 31, and the other main hinge seat is located on the other side of the two mounting plates 31. The two main rollers 32 are rotatably connected to the two main hinge seats through their own rotation shafts, so that the outer walls of the two main rollers 32 abut against the corresponding upper side of the track 2.

[0023] like Figure 3As shown, two secondary hinge seats are also fixed between the two mounting plates 31 by screws. One secondary hinge seat is located on one side of the two mounting plates 31, and the other secondary hinge seat is located on the other side of the two mounting plates 31. The two secondary hinge seats are located directly below the two main hinge seats. The two side rollers 33 are rotatably connected to the two secondary hinge seats through their own rotation axes. It is worth mentioning that after the main rollers 32 and the side rollers 33 are assembled, their arrangement orientation is actually different. Specifically, the rotation axis centerline of each side roller 33 is set vertically, and the axis centerline of each main roller 32 is arranged horizontally (and is connected to the connecting rod 11). The purpose of this arrangement is that the cross-section of the track 2 used in this embodiment is I-shaped. After the arrangement of each side roller 33 is completed, one of the two side rollers 33 in the same group abuts against one side outer wall of the corresponding track 2, and the other side roller 33 abuts against the other side outer wall of the corresponding track 2. Through this arrangement, the two main rollers 32 and the two side rollers 33 can drive the frame 1 to slide and adjust its position on the track 2. At the same time, the two main rollers 32 keep the frame 1 in the vertical direction in place, and the two side rollers 33 restrict and guide the sliding trajectory during the sliding process of the frame 1.

[0024] Secondly, two sets of motors 12 are provided on the frame 1. The motors 12 act as driving sources to drive the two sets of roller assemblies 3 on the connecting rod 11, thereby replacing the manual method to drive the frame 1 on the two tracks 2. As a specific solution, a U-shaped mounting bracket 311 is set on one side of the two mounting plates 31 in each set of roller assembly 3. The mounting bracket 311 is fixed to the two mounting plates 31 by screws. The motor 12 is fixed on the mounting bracket 311 and the rotating shaft is fixed to the rotating shaft of one of the main rollers 32 through a coupling.

[0025] Secondly, it is worth mentioning that, in order to ensure the smoothness of the frame 1 during the sliding process, two sets of roller assemblies 3 are also equipped on each long rod 13. The roller assembly 3 on each long rod 13 corresponds to the two tracks 2. It should be noted that the structure of each set of rollers on each long rod 13 is the same as that of the two sets of roller assemblies 3 on the connecting rod 11, and the installation method is also the same. Therefore, it will not be elaborated further. It is worth noting that, since the two sets of roller assemblies 3 on the connecting rod 11 are already equipped with motors 12 with sufficient power, in order to control costs, the roller assemblies 3 on the two long rods 13 do not need to be equipped with motors 12 again.

[0026] Automatic fire extinguishing devices are also equipped with corresponding sensor control systems. This structure can also adopt existing technology, such as the automatic fire extinguishing device for new energy vehicle batteries after thermal runaway disclosed in Chinese Patent (Application Publication No.: CN119857228A). In actual operation, the sensor control system detects and determines the ignition point. Then, by controlling the two motors 12, the frame 1 is moved horizontally to directly above the ignition point under the drive of each set of roller assemblies 3. Then, the fire blanket installed in the frame 1 is thrown down and covers the burning vehicle. As a further solution, in order to ensure sufficient control of the fire, one or more water pipes can be specially equipped in the frame 1. When the fire blanket is thrown down, water is sprayed onto the fire blanket through the arranged water pipes to cool the fire blanket.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0028] Although this document frequently uses terms such as frame 1, connecting rod 11, motor 12, long rod 13, short rod 14, track 2, roller assembly 3, mounting plate 31, mounting bracket 311, main roller 32, and side roller 33, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
