Description

Technical Field

[0001] The utility model relates to the technical field of energy storage system safety, in particular to a battery cluster cabinet with a detection function. Background Art

[0002] A battery pack is a whole composed of multiple battery cells. Its characteristics such as capacity, voltage and operating temperature range will be more stable than those of a single battery cell.

[0003] Battery clusters are being used more and more frequently. After prolonged, frequent use, the batteries will continue to age, degrading system safety performance. Overheating can also occur, leading to thermal runaway and its subsequent expansion, posing a safety hazard. When battery modules and cells malfunction, significant internal heat is generated and unable to dissipate. When temperatures reach critical levels, they can cause combustion or explosion of the battery module, leading to equipment fires and deflagrations. Therefore, ensuring battery module temperature safety and the proper installation of relevant fire prevention and control devices are paramount safety precautions.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example

[0032] like Figures 1 to 6 As shown, a battery cluster cabinet with a detection function includes a cluster cabinet 1, wherein battery racks 3 are provided on both sides of the cluster cabinet 1, each of the battery racks 3 is divided into a plurality of battery compartments 4 by partitions 5, and the battery compartments 4 are used to install battery modules 2. A functional area 9 is provided between the battery racks 3 on both sides of the cluster cabinet 1, and a detection component 6 is installed in the functional area 9;

[0033] The detection assembly 6 includes a screw 61 disposed in the functional area 9 and a motor 62 fixed to the top of the cluster cabinet 1. The bottom of the screw 61 is rotatably connected to the bottom plate of the cluster cabinet 1, and the output shaft of the motor 62 penetrates the cluster cabinet 1 and is fixedly connected to the top of the screw 61. A mounting seat 63 is screwed onto the screw 61. The outer ring of the screw 61 is also sleeved with a guide cylinder 65. The guide cylinder 65 is fixed between the top and bottom walls of the cluster cabinet 1 and is used to guide the mounting seat 63 to move up and down.

[0034] Detectors 64 are respectively installed on both ends of the mounting seat 63 facing the two battery racks 3 . The detectors 64 are located outside the guide cylinder 65 . The detectors 64 are electrically connected to a controller 8 , which is located outside the cluster cabinet 1 .

[0035] After the battery modules 2 are installed in the battery rack 3 , the opposite sides of the battery modules 2 on both sides of the cluster cabinet are hollowed out, making it easier for the detector 64 to detect abnormalities.

[0036] During use, the motor 62 drives the screw 61 to rotate, and the screw 61 is threadedly connected to the mounting base 63. The setting of the guide cylinder 65 enables the detector 64 on the mounting base 63 to move up and down for detection, thereby realizing the reciprocating detection of multiple battery modules 2 on both sides. It should be noted that the motor 62 is a forward and reverse motor. The motor 62 can be controlled to stay for a few seconds at each layer of battery modules 2 as needed to ensure the accuracy of the detection of the battery modules 2 on this layer.

[0037] In this embodiment, a fire extinguishing assembly 7 is also installed in the functional area 9, and the fire extinguishing assembly 7 includes a medium storage tank 71, which is installed on the top of the cluster cabinet 1. A first connecting pipe 72 is provided on the medium storage tank 71, and one end of the first connecting pipe 72 is connected to the medium storage tank 71, and the other end of the first connecting pipe 72 extends into the functional area 9 and is connected to two second connecting pipes 73 through a tee; the second connecting pipe 73 is vertically arranged; a plurality of vertically arranged third connecting pipes 74 are evenly connected to the second connecting pipe 73, each of the third connecting pipes 74 is horizontally arranged, and a plurality of the third connecting pipes 74 are installed with an electromagnetic valve 76, and the outlet of the third connecting pipe 74 is connected to a nozzle 75, and each of the nozzles 75 is respectively arranged toward the battery modules 2 on both sides.

[0038] When the detection assembly 6 detects a thermal runaway anomaly in a battery module 2 on a certain layer, the controller 8 determines the location of the anomaly based on the position and data of the detector 64, as well as whether the detection was made by the left or right detector 64. The controller then controls the solenoid valve 76 to open and extinguish the fire, achieving automatic fire extinguishing. It should be noted that the detector 64 can be a fire detector or a temperature detector, and the medium storage tank 71 contains a fire extinguishing medium.

[0039] In this embodiment, the mounting seat 63 includes an internally threaded sleeve 631 , and detector mounting pieces 632 are symmetrically provided on both sides of the internally threaded sleeve 631 . The detector 64 is fixed on the detector mounting pieces 632 .

[0040] In this embodiment, the inner diameter of the guide tube 65 is larger than the outer diameter of the internal threaded sleeve 631. The guide tube 65 is symmetrically provided with strip cuts extending in the vertical direction. The opening direction of the strip cuts is perpendicular to the side panel of the cluster cabinet 1; the detector mounting member 632 extends out of the strip cuts.

[0041] The inner diameter of the guide cylinder 65 is larger than the outer diameter of the internal threaded sleeve 631, which ensures that the threaded sleeve 631 will not be interfered with by the guide cylinder 65 when moving up and down. The guide cylinder 65 is fixed in the cluster cabinet 1, and the detector mounting part 632 and the detector 64 move up and down along the strip-shaped cutout of the guide cylinder to accurately detect the battery modules on both sides; further, the strip-shaped cutout limits the detector mounting part 632 so that it cannot rotate, ensuring that the detection direction of the detector 64 is forward detection.

[0042] In this embodiment, the plurality of solenoid valves 76 are all electrically connected to the controller 8 .

[0043] The controller 8 controls the switching of multiple solenoid valves 76 and can control one or more solenoid valves at the same time.

[0044] In this embodiment, the controller 8 is provided with an emergency switch button, and the controller 8 is also electrically connected to a buzzer.

[0045] When thermal runaway occurs, the buzzer will sound to notify the staff to handle it in time.

[0046] In this embodiment, a heat dissipation opening is provided on the back of the cluster cabinet 1 .

[0047] In this embodiment, a protective door 10 is provided on the cluster cabinet 1 located in the functional area 9 .

[0048] In this embodiment, the nozzle 75 is triangular in shape, and the nozzle of the nozzle 75 is strip-shaped.

[0049] In this embodiment, a gap is formed at the top of the battery compartment 5 after the battery module 2 is installed in the battery compartment 5, and the nozzle of the nozzle 75 corresponds to the gap.

[0050] The shape design of the nozzle 75 can enlarge the spraying area when extinguishing a fire, so that the fire extinguishing medium can be evenly sprayed onto the battery module 2 that has thermal runaway.

[0051] The working principle of the battery cluster cabinet with detection function in this utility model is as follows:

[0052] During use, the motor 62 drives the screw 61 to rotate, and the rotation of the screw 61 drives the mounting base 63 to move up and down, thereby driving the detectors 64 fixed on both sides of the mounting base 63 to move up and down. The detectors 64 detect the multi-layer battery modules 2 on both sides one by one. When the detector 64 detects that a battery module 2 has thermal runaway at a certain location, the controller controls the solenoid valve 76 at that location to open according to the data and position of the detector 64 to extinguish the fire, and notifies the staff through the sound of the buzzer, so that the fire can be dealt with in a timely and effective manner.

[0053] Finally, it should be noted that the detector 64, controller 8, solenoid valve 76, buzzer and other components involved in the present invention are all universal standard parts or components known to technical personnel in this field. Their structures and principles are known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in this field.

[0054] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
