Description

Technical Field

[0001] The invention relates to the field of battery protection, and in particular to a heat diffusion suppression fire prevention device for an energy storage battery. Background Art

[0002] Energy storage batteries are used to store electrical energy and can release it when needed. They improve the stability of the power system by providing functions such as frequency regulation and peak load transfer, and provide uninterrupted power supply for homes, commercial buildings and industrial facilities. During use, the battery will inevitably overheat. If the ambient temperature is also high at this time, there is a possibility of explosion and spontaneous combustion. Therefore, the storage of batteries needs to be strictly controlled. Conventional battery placement devices are equipped with fire prevention equipment to control the fire immediately after an accident. However, this device is relatively passive to use and lacks timeliness.

[0003] Therefore, in order to solve the above problems, a heat diffusion suppression fire prevention device for energy storage batteries is now developed. Summary of the invention

[0004] In order to overcome the shortcomings of existing devices that are relatively passive in use and lack timeliness, the present invention provides a heat diffusion suppression fire prevention device for energy storage batteries.

[0005] The technical implementation scheme of the present invention is: a heat diffusion suppression fire prevention device for energy storage batteries, including an installation frame, a fixed frame is connected to the bottom of the installation frame, a mobile frame is slidably connected to the fixed frame, four power supplies are placed in the mobile frame, a first cover plate is rotatably connected to the front side of the upper part of the installation frame, and a second cover plate is rotatably connected to the front side of the lower part of the installation frame, the first cover plate and the second cover plate are snap-fitted together, and also include: a suppression mechanism, which is arranged inside the installation frame, and is used to discharge inert gas in an emergency to suppress the spread of fire; a locking mechanism, which is arranged in the installation frame, and is used to lock and limit the movable frame.

[0006] As an improvement of the above-mentioned scheme, the suppression mechanism includes a gas cylinder, and the gas cylinders are installed on both sides of the left and right sides of the installation frame, and the gas cylinders are connected to gas valves. The rear side of the installation frame is connected to two first fixed cylinders that are symmetrical on the left and right, and the first fixed cylinders are slidably connected to the first fixed cylinders, and compressed gas is stored in the mobile cylinders. The front side of the first fixed cylinders is connected to a baffle plate for limiting and blocking the adjacent mobile cylinders, and the front side of the mobile cylinders is connected to a limiting member for pushing and controlling the gas valves.

[0007] As an improvement on the above scheme, the locking mechanism includes a first fixed frame, the first fixed frame is connected to the left and right sides of the movable frame, two second fixed frames are symmetrically connected to the rear side of the installation frame, the first fixed frame and the adjacent second fixed frame are slidably connected, the first fixed frame and the adjacent second fixed frame are connected with a spring, the front of the installation frame is connected to a lock plate, the upper left and right sides of the installation frame are connected to fixed blocks, the fixed blocks are slidably connected with a lifting member for blocking and limiting the lock plate, the upper left and right sides of the movable frame are connected to temperature sensors, the lower part of the lifting member is connected to racks, drive motors are installed on the left and right sides of the installation frame, the drive motors are controlled by the temperature sensors, gears are connected to the output shafts of the drive motors, and the gears are meshed with the adjacent racks.

[0008] As an improvement of the above scheme, a heat absorption mechanism is also included, which includes a mounting frame, the mounting frame is connected to the fixed frame, and a heat absorption component is installed in the mounting frame. The heat absorption component liquefies when heated to improve the heat absorption effect.

[0009] As an improvement of the above scheme, a supporting mechanism is also included, which includes a second fixed cylinder, the second fixed cylinders are connected to the left and right sides of the installation frame, the second fixed cylinders are slidably connected to support members for supporting the second cover plate, the second fixed cylinders are connected to two conduits, a hydraulic cylinder is connected between two adjacent conduits, a push rod is slidably connected in the hydraulic cylinder, and the push rod is fixedly connected to the adjacent first fixed frame.

[0010] As an improvement of the above solution, a fan is also included. Two fans are installed on both sides of the upper left and right sides of the installation frame, and the fans are used to increase the flow speed of the internal airflow.

[0011] As an improvement of the above solution, a protruding rod is further included. The front sides of the left and right parts of the movable frame are both connected with the protruding rod. The protruding rod is used to push the first cover plate and the second cover plate so that the first cover plate and the second cover plate can be opened normally.

[0012] As an improvement of the above solution, an integrated power port is connected to the first cover plate, and the power port is electrically connected to the power source.

[0013] As an improvement of the above solution, the baffle is made of fragile material.

[0014] By adopting the above technical solution, the advantages of the present invention are: 1. When the power supply overheats and causes the temperature in the installation frame to rise sharply, the suppression mechanism of the present invention will automatically start and discharge the inert gas to fill the interior of the installation frame to prevent the power supply from spontaneously igniting. At the same time, the locking mechanism will be opened urgently, so that the mobile frame will pop out, and the power supply will be cooled, thereby strengthening the automatic protection effect of the power supply and improving the safety of the device.

[0015] 2. When the temperature inside the installation frame begins to rise, the heat generated by the power supply is absorbed and dissipated by the heat absorber to prevent the battery temperature from rising rapidly in a high temperature environment and reduce the risk of overheating and explosion of the power supply.

[0016] 3. As the temperature inside the installation frame is too high, the temperature sensor is triggered, causing the mobile frame to pop out forward. At this time, the first fixed frame will synchronously pull the push rod forward, so that the telescopic rod moves forward along the hydraulic cylinder. At this time, the hydraulic pressure in the hydraulic cylinder changes, and the pressure is transmitted downward by the conduit, so that the support member automatically slides forward to support the flipped second cover plate, thereby improving the supporting effect of the second cover plate on the mobile frame and preventing the second cover plate from being crushed by the mobile frame.

DETAILED DESCRIPTION

[0031] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments. Example 1

[0032] A heat diffusion suppression fire prevention device for energy storage batteries, such as Figure 1-Figure 3 As shown, it includes an installation frame 1, a fixed frame 3 is connected to the bottom of the installation frame 1, a mobile frame 2 is slidably connected to the fixed frame 3, four power supplies 4 are placed in the mobile frame 2, a first cover plate 5 is rotatably connected to the front side of the upper part of the installation frame 1, an integrated power supply port 4 is connected to the first cover plate 5, the power supply port 4 is electrically connected to the power supply 4, a second cover plate 6 is rotatably connected to the front side of the lower part of the installation frame 1, the first cover plate 5 and the second cover plate 6 are snap-fitted together, and also includes: a suppression mechanism 7, which is arranged inside the installation frame 1, and is used to discharge inert gas in an emergency to suppress the spread of fire; a locking mechanism 8, which is arranged in the installation frame 1, and is used to lock and limit the mobile frame 2.

[0033] It should be noted that under normal circumstances, the power supply 4 is stored by relying on the installation frame 1 and the mobile rack 2. When the power supply 4 is needed, the power supply 4 port is connected to the external device to use the electric energy in the power supply 4. When the power supply 4 overheats and causes the temperature in the installation frame 1 to rise sharply, the suppression mechanism 7 will start automatically and discharge the inert gas to fill the interior of the installation frame 1 to prevent the power supply 4 from self-igniting. At the same time, the locking mechanism 8 will be opened urgently, so that the mobile rack 2 will pop out to dissipate the heat of the power supply 4.

[0034] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the suppression mechanism 7 includes a gas cylinder 71, gas cylinders 71 are installed on both sides of the left and right sides of the installation frame 1, gas valves 72 are connected to the gas cylinders 71, two left and right symmetrical first fixed cylinders 73 are connected to the rear side of the installation frame 1, and moving cylinders 74 are slidably connected to the first fixed cylinders 73, compressed gas is stored in the moving cylinders 74, and the front sides of the first fixed cylinders 73 are connected to baffle plates 75 for limiting and blocking adjacent moving cylinders 74, the baffle plates 75 are made of fragile material, and the front sides of the moving cylinders 74 are connected to limit members 76 for pushing and controlling the gas valves 72.

[0035] It should be noted that when the ambient temperature inside the installation frame 1 becomes higher and higher, the compressed gas in the movable cylinder 74 will begin to expand rapidly due to the influence of the temperature, thereby causing the baffle 75 on the front side of the first fixed cylinder 73 to be impacted and broken. At this time, the movable cylinder 74 is no longer blocked. Under the action of the gas expansion, the movable cylinder 74 will generate a forward sliding force, thereby causing the limit members 76 to move forward and push the gas valve 72 to open. When the movable cylinder 74 moves to the extreme position, the air vent on the movable cylinder 74 is no longer blocked. At this time, the compressed gas in the movable cylinder 74 will be depressurized and discharged, and the inert gas in the gas cylinder 71 will be discharged outward through the gas valve 72, filling the interior of the installation frame 1 with the inert gas to prevent the power supply 4 from overheating and spontaneous combustion.

[0036] like Figure 2 , Figure 7 , Figure 8 and Fig. 9As shown, the locking mechanism 8 includes a first fixed frame 81, the first fixed frame 81 is connected to the left and right sides of the movable frame 2, two second fixed frames 82 are connected to the rear side of the installation frame 1, the first fixed frame 81 and the adjacent second fixed frame 82 are slidably connected, and springs 83 are connected between the first fixed frame 81 and the adjacent second fixed frame 82, a locking plate 84 is connected to the front of the installation frame 1, fixed blocks 85 are connected to the left and right sides of the upper part of the installation frame 1, and lifting members 86 for blocking and limiting the locking plate 84 are slidably connected to the fixed blocks 85, and temperature sensors 88 are connected to the left and right sides of the upper part of the movable frame 2, and racks 89 are connected to the lower parts of the lifting members 86, and driving motors 811 are installed on the left and right sides of the installation frame 1, and the driving motors 811 are controlled by the temperature sensors 88, and gears 810 are connected to the output shafts of the driving motors 811, and the gears 810 are meshed with the adjacent racks 89.

[0037] It should be noted that, in the initial placement state, the springs 83 are all in a stressed and compressed state. When the temperature sensor 88 detects that the temperature inside the installation frame 1 is too high, it will automatically start the drive motor 811. The output shaft of the drive motor 811 drives the corresponding gear 810 to rotate, which will cause the adjacent racks 89 to move downward, thereby driving the lifting member 86 to slide downward along the adjacent fixed block 85. As the lifting member 86 slides downward, the lock plate 84 is no longer blocked by the lifting member 86. Under the action of the spring 83, the movable frame 2 will pop up directly forward, breaking through the obstruction of the first cover plate 5 and the second cover plate 6, so that the interior of the installation frame 1 is no longer in a closed state, realizing open heat dissipation treatment. Example 2

[0038] On the basis of Example 1, Figure 2 and Fig.10 As shown, a heat absorbing mechanism 9 is also included. The heat absorbing mechanism 9 includes a mounting frame 91. The mounting frame 91 is connected to the fixed frame 3. A heat absorbing component 92 is installed in the mounting frame 91. The heat absorbing component 92 liquefies when heated to improve the heat absorbing effect.

[0039] It should be noted that when the temperature inside the mounting frame 1 begins to rise, the heat generated by the power source 4 is absorbed and dissipated by the heat absorbing member 92, thereby preventing the battery temperature from rising rapidly in a high temperature environment and reducing the risk of overheating and explosion of the power source 4.

[0040] like Figure 2 ,like Fig.11 and Fig.12As shown, it also includes a supporting mechanism 10, which includes a second fixed cylinder 101. The second fixed cylinders 101 are connected to the left and right sides of the inside of the installation frame 1. The second fixed cylinders 101 are slidably connected to support members 102 for supporting the second cover plate 6. The second fixed cylinders 101 are connected to two conduits 104. A hydraulic cylinder is connected between two adjacent conduits 104. A push rod 105 is slidably connected in the hydraulic cylinder. The push rod 105 is fixedly connected to the adjacent first fixed frame 81.

[0041] It should be noted that, as the temperature inside the installation frame 1 is too high, the temperature sensor 88 is triggered, causing the movable frame 2 to be ejected forward. At this time, the first fixed frame 81 will synchronously pull the push rod 105 to move forward, thereby causing the telescopic rod 103 to move forward along the hydraulic cylinder. At this time, the hydraulic pressure in the hydraulic cylinder changes, and the pressure is transmitted downward by the conduit 104, so that the support member 102 automatically slides forward to support the flipped second cover plate 6, thereby improving the supporting effect of the second cover plate 6 on the movable frame 2 and preventing the second cover plate 6 from being crushed by the movable frame 2.

[0042] like Figure 2 and Fig.13 As shown, a fan 11 is also included. Two fans 11 are installed on both sides of the upper left and right sides of the installation frame 1. The fans 11 are used to increase the flow speed of the internal airflow.

[0043] like Figure 2 and Fig.13 As shown, it also includes a protruding rod 12. The front sides of the left and right parts of the moving frame 2 are both connected with the protruding rod 12. The protruding rod 12 is used to push the first cover plate 5 and the second cover plate 6 so that the first cover plate 5 and the second cover plate 6 can be opened normally.

[0044] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
