Description

Technical Field

[0001] The present invention relates to the field of energy storage battery fire-fighting devices, and in particular to a modular energy storage battery fire-fighting emergency device. Background Art

[0002] Modular batteries are an innovative battery technology that designs battery systems into multiple standardized, combinable, and interchangeable modules. These modules contain battery cells, a battery management system, a cooling system, and a housing, and are electrically connected and mechanically fixed to form a complete battery pack. They offer advantages such as high flexibility, strong maintainability, enhanced safety, excellent scalability, and environmental protection and energy conservation. They are widely used in electric vehicles, energy storage systems, portable electronic devices, and power tools, enabling flexible configuration of battery solutions tailored to the specific needs of different application scenarios.

[0003] The invention patent with announcement number CN109671891A discloses a modular battery, which is arranged in the battery compartment according to the structure of the battery compartment. When the model of the electric forklift changes, it is only necessary to select the number of battery modules according to the structure of the battery compartment. Moreover, different voltages and currents can be generated through different series and parallel connection methods between the battery cells to meet the voltage and current requirements of different models of forklifts, thereby realizing modular design.

[0004] In the existing technology, energy storage batteries use a dovetail structure design to strengthen the connection strength between batteries, making the modular assembly of batteries more stable and reliable. However, since the energy storage batteries are close to each other, when one battery fails and the temperature is too high, it is easy to affect the adjacent batteries, causing the damage range to expand, increasing the damaged area, and more likely to cause spontaneous combustion and explosion.

[0012] The first sector gear and the second sector gear are intermittently and staggeredly meshed with the tooth plate. When the first sector gear is meshed with the tooth plate, it is used to control the two isolation plates to move away from each other. When the second sector gear is meshed with the tooth plate, it is used to control the two isolation plates to move closer to each other.

[0014] Furthermore, when the real-time temperature value detected by the temperature sensor located around the energy storage battery exceeds a preset value, the control module is also used to control the two isolation plates to move closer to each other until the opening of the isolation cavity is sealed.

[0015] Furthermore, the invention further comprises an auxiliary component, the auxiliary component comprising a movable groove provided on the top of the tooth plate, a guide block fixedly mounted on the inner wall of the movable groove, a first lifting rod slidably mounted on one side of the guide block, and an inclined groove formed on one side of the first lifting rod; the inclined groove slidably engages with the inclined portion on the guide block, and is used to provide an upward lifting force to the lower fixed frame when the tooth plate moves;

[0016] A second lifting rod is provided at the top of the first lifting rod, and the top of the second lifting rod is connected to a rotating rod, and the end of the rotating rod away from the second lifting rod abuts against the top of the lower fixed frame, and a second rotating shaft is rotatably installed at the midpoint of the rotating rod, and a support rod is fixedly installed at the bottom end of the second rotating shaft, and the support rod is fixedly installed at the top of the isolation chamber; a sliding groove for the sliding of the first lifting rod is opened at the bottom end of the second lifting rod, and an extrusion spring is provided between the first lifting rod and the sliding groove.

DETAILED DESCRIPTION

[0032] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] The present invention proposes a modular energy storage battery fire emergency device. In this modular energy storage battery fire emergency device, a disengagement component is provided so that when the temperature sensor detects that the temperature of the corresponding energy storage battery 1 exceeds a preset threshold, the temperature sensor can send a signal to control the power motor 11 to start, thereby driving the isolation plate 6 to open, so that the energy storage battery 1 loses the support of the isolation plate 6 and falls into the isolation cavity 5 under the action of its own gravity, cutting off the connection with other energy storage batteries 1 and preventing its own high temperature from affecting adjacent energy storage batteries 1, thereby improving the safety and reliability of the device.

[0034] Example 1:

[0035] In this embodiment, a modular energy storage battery fire emergency device has a structure as follows: Figure 1 、 Figure 2 、 Figure 4 and Figure 8 As shown, Figure 2 、 Figure 4 、 Figure 8 Only part of the fire emergency device is shown, mainly showing the parts related to the present invention, such as Figures 1 to 9 As shown, a modular energy storage battery fire emergency device includes an energy storage battery 1, a box body 3 (for accommodating the energy storage battery 1 in an emergency state), and a temperature sensor and control module (not shown) located on the side of the energy storage battery 1. The box body 3 is provided with an isolation mechanism connected to the control module signal. The isolation mechanism includes an isolation cavity 5 located in the box body 3 and an opening component located at the opening of the isolation cavity 5. When the real-time temperature value detected by the temperature sensor located on the side of the energy storage battery 1 exceeds a preset value, the control module controls the opening component to operate, causing the energy storage battery 1 to fall into the isolation cavity 5 and disconnect the electrical connection point of the energy storage battery 1. The device also includes a fixing frame 13 that is movably connected to the top of multiple adjacent energy storage batteries 1. The top of the fixing frame 13 is provided with positive and negative electrode interfaces that abut the positive and negative electrodes of the energy storage battery 1. The outer walls of the multiple positive and negative electrode interfaces are connected with copper plates 14. The upper and lower sides of the multiple energy storage batteries 1 are respectively provided with an upper fixing frame 12 and a lower fixing frame 2. The opening assembly includes a set of relatively slidable isolation plates 6 positioned between the opening of each isolation cavity 5 and each lower fixing frame 2. The isolation plates 6 are used to support and limit the position of the energy storage batteries 1. A mounting plate 4 is provided on one side of each lower fixing frame 2 and is fixedly mounted to the top of the box body 3.

[0036] In this embodiment, when assembling the modular energy storage battery fire emergency device, a corresponding number of energy storage batteries 1 and a lower fixing frame 2 are selected according to actual needs. The lower fixing frame 2 is installed on one side of the mounting plate 4 through the dovetail structure designed on both sides of the lower fixing frame 2, and the energy storage battery 1 is installed in the lower fixing frame 2. At this time, the upper fixing frame 12 is sleeved on the top of the energy storage battery 1 through the through groove opened at the top of the fixing frame 13, and the copper plate 14 is placed according to the actual required current and voltage characteristics so that the copper plate 14 is engaged with the electrode at the top of the energy storage battery 1 to complete the assembly of the energy storage battery 1. The isolation cavity 5 is preferably made of mica board material, which has excellent insulation and high temperature resistance. It can enable the isolation cavity 5 to maintain good electrical insulation performance at high temperatures, effectively prevent leakage that may occur when the battery fails, and also provide good heat insulation.

[0037] It can be understood that there is a gap between each group of isolation plates 6, and the distance between each group of isolation plates 6 is smaller than the distance between the two sides of the lower fixed frame 2, so that the isolation plates 6 can provide support for the energy storage battery 1 and the lower fixed frame 2.

[0038] like Figure 2-5 As shown, further preferably, under each energy storage battery 1, a toothed plate 7 is fixedly mounted on one side of one isolation plate 6, and a first sector gear 8 and a second sector gear 15 are meshed and mounted on one side of the toothed plate 7. A first synchronous gear 9 is fixedly mounted on the bottom end of the first sector gear 8, and a second synchronous gear 10 is meshed and mounted on one side of the first synchronous gear 9. A power motor 11 is fixedly mounted on the bottom end of the second synchronous gear 10 (the power motor 11 is a mature existing technology, so its internal structure is not described in detail. The model used in this embodiment is F130); the first sector gear 8 and the second sector gear 15 are intermittently and staggeredly meshed with the toothed plate 7. When the first sector gear 8 is meshed with the toothed plate 7, it is used to control the two isolation plates 6 to move away from each other. When the second sector gear 15 is meshed with the toothed plate 7, it is used to control the two isolation plates 6 to move closer to each other. When the real-time temperature value detected by the temperature sensor located on the side of the energy storage battery 1 exceeds a preset value, the control module is also used to control the two isolation plates 6 to move closer to each other until the opening of the isolation cavity 5 is sealed. When the power motor 11 drives the isolation plate 6 to move through the second synchronous gear 10, the first synchronous gear 9, the first sector gear 8 and the tooth plate 7, the gap between the isolation plates 6 is just enough to allow the energy storage battery 1 and the lower fixed frame 2 to pass through; after the isolation plate 6 is opened to allow the energy storage battery 1 and the lower fixed frame 2 to fall into the isolation chamber 5, the power motor 11 continues to drive the second synchronous gear 10 to rotate. At this time, the second synchronous gear 10 drives the second sector gear 15 to engage with the tooth plate 7, so that the second sector gear 15 drives the tooth plate 7 to start moving in the opposite direction, and the tooth plate 7 drives the isolation plate 6 to move, so that the isolation plates 6 abut against each other and close, sealing the isolation chamber 5, thereby preventing heat from escaping and affecting other energy storage batteries 1, and when the energy storage battery 1 spontaneously combusts, it can also isolate the air and effectively suppress the spontaneous combustion of the energy storage battery 1.

[0039] It should be noted that, in this embodiment, the first sector gear 8 and the second sector gear 15 are intermittently and staggeredly meshed with the tooth plate 7. When the first sector gear 8 or the second sector gear 15 is meshed with the tooth plate 7, the other sector gear is not meshed with the tooth plate 7. After the first sector gear 8 or the second sector gear 15 stops meshing with the tooth plate 7, the power motor 11 continues to drive the second synchronous gear 10 to rotate a certain angle before the other sector gear starts to mesh with the tooth plate 7, thereby avoiding the problem of motion interference caused by the first sector gear 8 and the second sector gear 15 being meshed with the tooth plate 7 at the same time. In addition, through the design of intermittent meshing, the isolation plate 6 starts to close after a period of time after opening, thereby giving the energy storage battery 1 and the lower fixed frame 2 enough time to fall into the isolation cavity 5, thereby improving the stability and reliability of the device.

[0040] In specific implementation, the temperature sensors are all arranged on the surrounding side of the energy storage battery 1 (not shown in the figure). In order to detect the high temperature phenomenon of the energy storage battery 1 more timely and effectively, the temperature sensor is arranged inside the upper fixing frame 12 in this embodiment. Since the temperature of the electrode area of the energy storage battery 1 tends to rise earlier during the charging process, the temperature sensor is arranged inside the upper fixing frame 12. When a fault occurs in the energy storage battery 1 and the temperature rises, it can detect and respond in time. The energy storage batteries 1 in the prior art are relatively close to each other. When one of the energy storage batteries 1 fails and the temperature rises, it is easy to affect the surrounding energy storage batteries 1, making the equipment prone to thermal runaway, and then causing fire and explosion. The energy storage battery 1 adopts the separation component of the present embodiment. When the temperature of the energy storage battery 1 rises due to a fault, the temperature sensor detects that the temperature in the corresponding energy storage battery 1 exceeds the preset threshold, thereby sending a signal and controlling the power motor 11 to start, so that the power motor 11 drives the isolation plate 6 to open through the second synchronous gear 10, the first synchronous gear 9, the first sector gear 8 and the tooth plate 7, so that the energy storage battery 1 falls into the isolation cavity 5 under the action of gravity, thereby disconnecting the faulty energy storage battery 1 from other energy storage batteries 1 and isolating the faulty energy storage battery 1 from other energy storage batteries 1, preventing the high temperature of the faulty energy storage battery 1 from affecting other energy storage batteries 1, avoiding further expansion of the danger, and improving the safety of the equipment.

[0041] like Figure 8 and Figure 9 As shown, further preferably, under each energy storage battery 1, a synchronization rod 16 is fixedly installed at the bottom end of one of the isolation plates 6 away from the tooth plate 7. The end of the synchronization rod 16 away from the isolation plate 6 is rotatably connected to a synchronization bar 17, which rotates around a first rotation axis 18, and the first rotation axis 18 is fixedly installed inside the box body 3. In this way, when one isolation plate 6 moves, the isolation plate 6 will drive the synchronization bar 17 to rotate around the first rotation axis 18 through the synchronization rod 16, so that the synchronization bar 17 drives the other synchronization rod 16 to move, thereby driving the other isolation plate 6 to move the same distance. This design can reduce the number of disengagement components and isolation mechanisms and reduce resource consumption. On this basis, further optimization is performed, and the bottom end of the isolation plate 6 without the tooth plate 7 is provided with a guide block, and the inner wall of the guide block is slidably mounted with a guide rod 19, which is fixedly installed on the inner wall of the box body 3, thereby improving the stability of the isolation plate 6 during movement and preventing the isolation plate 6 from offsetting during movement, thereby causing the sealing of the isolation chamber 5 to decrease.

[0042] Example 2:

[0043] On the basis of Example 1, further supplementary explanation is given. In this embodiment, an auxiliary component is preferably used, such as Figures 4 to 6As shown, when the isolation plate 6 moves, it can drive the first lifting rod 22 to move up and down through the moving groove 20 and the guide block 21, wherein an inclined groove 23 is opened on one side of the first lifting rod 22, and a second lifting rod 24 is provided at the top of the first lifting rod 22. The top of the second lifting rod 24 is connected to a rotating rod 25, and the end of the rotating rod 25 away from the second lifting rod 24 abuts against the top of the lower fixed frame 2. The midpoint of the rotating rod 25 is rotatably installed with a second rotating shaft 26, and the bottom end of the second rotating shaft 26 is fixedly installed with a support rod 27, and the support rod 27 is fixedly installed at the top of the isolation chamber 5. This design makes it possible for the first lifting rod 22 to drive the second lifting rod 24 to move when it moves, and the second lifting rod 24 gives the lower fixed frame 2 a downward thrust through the rotating rod 25, so that the energy storage battery 1 and the lower fixed frame 2 can fall quickly. Since the electrode at the top of the energy storage battery 1 is socketed with the copper plate 14, when the isolation plate 6 at the bottom end of the energy storage battery 1 is opened, the energy storage battery 1 needs some time to contact the copper plate 14 Separation, thereby slowing down the effective time of isolation protection and increasing safety hazards. By setting an auxiliary component, when the separation component opens the isolation plate 6, a downward thrust can be simultaneously given to the lower fixed frame 2, so that the lower fixed frame 2 can quickly drive the energy storage battery 1 to separate from the copper plate 14 and perform isolation operation. Further preferably, a slide groove is provided at the bottom end of the second lifting rod 24, so that the first lifting rod 22 can slide therein, and an extrusion spring 28 is provided between the first lifting rod 22 and the slide groove. This design can avoid the problem that when the isolation plate 6 is opened, one end of the rotating rod 25 begins to apply force to the lower fixed frame 2, thereby increasing the load and wear of the isolation plate 6, and then hindering the operation of the isolation plate 6. The extrusion spring 28 can be provided for buffering. On the one hand, the wear on the isolation plate 6 can be reduced. On the other hand, the explosive force of the thrust applied to the lower fixed frame 2 can be increased when the isolation plate 6 is opened, so that the energy storage battery 1 and the lower fixed frame 2 can enter the isolation cavity 5 more quickly.

[0044] Example 3:

[0045] like Figure 4 and Figure 7As shown, in order to further reduce safety hazards, the present embodiment is provided with a buffer assembly, which includes a buffer plate 29 arranged in the isolation cavity 5, and a buffer spring 30 is symmetrically installed on the bottom end of the buffer plate 29. This design can provide a buffering effect on the energy storage battery 1 and the lower fixed frame 2 when the energy storage battery 1 and the lower fixed frame 2 fall into the isolation cavity 5, thereby preventing the energy storage battery 1 and the lower fixed frame 2 from easily expanding and impacting when falling into the isolation cavity 5, thereby causing the internal expansion and explosion of the energy storage battery 1, causing safety hazards. In addition, the inner wall of the isolation cavity 5 is also provided with a protrusion with a dovetail structure that fits on one side of the lower fixed frame 2, so that the energy storage battery 1 and the lower fixed frame 2 can guide their displacement when falling, so that the force distribution when the energy storage battery 1 and the lower fixed frame 2 hit the buffer plate 29 is more even. The cam is uniform, thereby further reducing the occurrence of safety hazards, and the cross-section of the protrusion is smaller than the cross-section of the dovetail structure on one side of the lower fixed frame 2, so as to avoid a small offset of the lower fixed frame 2 when falling, which causes the protrusion to hinder the falling of the lower fixed frame 2. The bottom of the isolation chamber 5 is provided with a detachable movable plate. Since the buffer spring 30 operates in a high temperature and high pressure environment, it is easy to accelerate aging. Therefore, a detachable movable plate is provided to facilitate maintenance personnel to maintain and replace the buffer spring 30. Furthermore, the distance between the two ends of the buffer spring 30 is greater than the distance between the two ends of the lower fixed frame 2. A limiting rod 31 is installed at both ends of the buffer spring 30, wherein the limiting rod 31 is provided with a rod body and a rod cap. The buffer spring 30 is guided by the rod body and limited by the rod cap.

[0046] Further preferably, in this embodiment, Figures 7 to 9As shown, a control rod 32 is fixedly installed on the top of one end of the buffer plate 29, and a release tube 33 is provided on the top of the control rod 32. The control rod 32 passes through the release tube 33 and extends to the top of the release tube 33. One end of the release tube 33 passes through the isolation chamber 5 and extends to one side of the isolation chamber 5. The end of the release tube 33 extending to one side of the isolation chamber 5 is connected to a connecting tube 34. The other ends of the connecting tube 34 are respectively installed with compression bottles 35, wherein the compression bottles 35 store compressed carbon dioxide. A through hole is opened on the top of the control rod 32, and the diameter of the cross section of the through hole is equal to the cross section diameter of the release tube 33. Under normal circumstances, the control rod 32 closes the release tube 33 to prevent carbon dioxide from escaping. If the energy storage battery 1 spontaneously combusts, when the energy storage battery 1 and the lower fixed frame 2 fall into the isolation chamber 5 and drive the buffer plate 29 to move, the buffer plate 29 drives the control rod 32 to move, so that the through hole at the top of the control rod 32 moves to the side of the release tube 33. At this time, the carbon dioxide stored in the compression bottle 35 moves into the isolation chamber 5 through the connecting tube 34 and the release tube 33, and cooperates with the closed environment formed by the isolation plate 6 to extinguish the fire of the energy storage battery 1. At the same time, a storage box 36 is provided on the side of the isolation chamber 5 close to the connecting tube 34, so that the compression bottle 35 is stored therein. A sliding cover 37 is slidably installed on one side of the storage box 36, which can facilitate maintenance personnel to replace the compression bottle 35.

[0047] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
