Description

Technical Field

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

[0002] An energy storage power station consists of several battery clusters, each of which contains several battery modules, and each battery module contains several battery cells. To ensure efficient electrochemical reactions within the battery modules, both the battery cells and modules are sealed.

[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.

[0004] Chinese patent CN219290480U discloses a fire prevention and control system for battery boxes in energy storage power stations, which relates to the field of safety technology for lithium battery energy storage power stations. When the first detection module at any battery cluster detects that a certain parameter reaches a fire threshold, it sends a signal to the fire control host and opens the corresponding valve. The control host activates the fire extinguishing device, which then precisely sprays the corresponding fire extinguishing medium through the valve to the battery cluster corresponding to the fire, achieving precise fire extinguishing.

[0005] The above patent solves the problem of fire prevention and control to a good extent, but does not deal with the heat generated by the battery cluster, and the risk of fire is still relatively high. Therefore, on the basis of setting up fire prevention and control, the overall temperature of the battery cluster also needs to be controlled to reduce the occurrence of accidents.

DETAILED DESCRIPTION

[0027] 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.

[0028] Example

[0029] like Figures 1 to 5 As shown, a safety detection battery cluster cabinet includes a cluster cabinet 1 and a battery module 2. A partition 4 is provided in the cluster cabinet 1; multiple layers of battery plug-in boxes 3 are provided on one side of the partition 4, and the battery modules 2 are installed in each layer of the battery plug-in boxes 3; a sensing channel 7 is provided between the partition 4 and each layer of the battery plug-in boxes 3, and a spray channel 8 for accommodating a nozzle 59 is provided on the partition 4, and the nozzle 59 can spray a fire extinguishing agent; a detection component 5 for detecting thermal runaway is provided on the other side of the partition 4; and a cooling component 6 is also provided in the cluster cabinet 1.

[0030] The battery module 2 is installed in the cluster cabinet 1 , and the detection component 5 and the cooling component 6 protect the battery module 2 .

[0031] In this embodiment, the detection assembly 5 includes a controller 52, a fire extinguishing agent storage tank 53, and a motor 56. The controller 52, the fire extinguishing agent storage tank 53 and the motor 56 are all located at the top of the cluster cabinet 1; a plurality of the sensing channels 7 are each fixed with a detector 51, the detector 51 being fixed at the top of the sensing channel 7, and the plurality of the detectors 51 are electrically connected to the controller 52; the controller 52 is electrically connected to the motor 56, the output end of the motor 56 penetrates the cluster cabinet 1 and is fixedly connected to a transmission screw 57, the bottom of the transmission screw 57 is rotatably connected to the bottom of the cluster cabinet 1, a nozzle mounting seat 58 is screwed on the transmission screw 57, the nozzle mounting seat 58 is fixed with the nozzle 59, the spraying end of the nozzle 59 extends into the spray channel 8, the tail of the nozzle 59 is connected to the fire extinguishing agent storage tank 53 through a hose 54, and nozzle limiting rods 55 are provided on both sides of the nozzle 59, and the nozzle limiting rods 55 are vertically fixed between the top wall and the bottom wall of the cluster cabinet 1.

[0032] A detector 51 is installed in each sensing channel 7 to monitor the battery modules 2 within each battery compartment 3 in real time. A motor 56 powers the rotation of a screw 57. A nozzle mounting base 58 is threadedly connected to the screw 57. Stop rods 55 are provided on either side of the nozzle 59 to limit the nozzle 59, creating a screw drive between the screw 57 and the nozzle 59, enabling the nozzle 59 to move up and down along the spray channel 8. It should be noted that each detector 51 is numbered, and the controller 52 is a PLC controller. The controller 52 controls the speed of the motor 56 and, in combination with the pitch of the screw 57, precisely controls the distance traveled by the nozzle 59. During use, when the detector 51 detects thermal runaway, it converts the signal into an electrical signal and transmits it to the controller 52. The controller 52 drives the motor according to the specific position of the detector 51. After the nozzle 59 is moved to the desired fire extinguishing position, the one-way solenoid valve 532 is opened to extinguish the fire, thereby achieving timely fire extinguishing.

[0033] It should be noted that the detector 51 may be a smoke detector, a temperature detector, or a gas detector. After the fire is extinguished, the nozzle 59 needs to be returned to its initial position to facilitate continued monitoring.

[0034] In this embodiment, the cooling component 6 includes a coil 61 fixed on the top wall of each battery plug box 3 and a water reservoir 64 placed on the right side of the cluster cabinet 1. The water inlet and outlet ends of the multiple coils 61 extend into the cluster cabinet 1 on the right side through the spray channel 8; the water inlet ends of the multiple coils 61 are connected to the water inlet main pipe 62, and the water outlet ends of the multiple coils 61 are connected to the water outlet main pipe 63; the other ends of the water inlet main pipe 62 and the water outlet main pipe 63 are connected to the water reservoir 64; the water inlet main pipe 62 is also connected to a liquid delivery pump 65; a plurality of heat sinks 66 are fixed on the water reservoir 64, and a heat dissipation port is also opened at the bottom right side of the cluster cabinet 1, and a plurality of heat sinks 66 extend out of the cluster cabinet 1 through the heat dissipation port.

[0035] During operation, the battery modules 2 generate internal heat, which is dissipated within the cabinet and conducted to the bottom plate of the battery compartments 3. Coils 61 are installed on the top wall of each battery compartment 3. Cooling liquid flows through the coils 61, removing heat from the bottom plate and the top gap of the battery compartment 3, thereby reducing the temperature. During operation, a liquid delivery pump 65 draws cooling liquid into the water inlet main pipe 62, which then flows into the coils 61 installed on the top wall of each battery compartment 3. The coils 61 absorb heat and discharge the heated liquid into the water outlet main pipe 63, which then discharges it into the water reservoir 64 for mixed cooling. Furthermore, the water reservoir 64 is fixed with multiple heat sinks 66. These heat sinks 66 extend outside the cluster cabinet 1 through heat dissipation ports, allowing for free ventilation and heat dissipation. This accelerates the cooling of the water in the water reservoir 64. This cycle ensures that the temperature of the battery modules 2 does not rise too high. It should be noted that, if necessary, a fan can be used to blow air over the heat sinks 66 to dissipate heat.

[0036] In this embodiment, fixed side panels 9 are fixed on both sides of the entrance of the battery box 3, and limiting side panels 10 are provided on both sides of the battery module 2 panel. The fixed side panels 9 and the limiting side panels 10 are connected by pins.

[0037] The fixed side plate 9 and the limiting side plate 10 can control the insertion depth of the battery module 2. The fixed side plate 9 and the limiting side plate 10 are connected by a pin, which can fix the battery module 2 in the battery insertion box 3 to increase stability.

[0038] In this embodiment, a ventilation hole is provided between the back of the cluster cabinet 1 and each battery plug box 3 .

[0039] In this embodiment, the fire extinguishing agent storage tank 53 is provided with an air outlet interface 531, and a one-way solenoid valve 532 is also installed on the air outlet interface 531. The one-way solenoid valve 532 is electrically connected to the controller 52, and the fire extinguishing agent storage tank 53 is connected to the hose 54 through the outlet of the air outlet interface 531.

[0040] In this embodiment, the controller 52 is electrically connected to a buzzer. When the detector 51 detects an abnormality, the controller 52 turns on the buzzer to remind the staff to carry out further processing.

[0041] In this embodiment, the cross section of the sensing channel 7 is rectangular, and the top wall of the sensing channel 7 is flush with the top wall of the battery compartment 3, so that the specific location where the abnormality occurs can be better detected.

[0042] In this embodiment, the spray channel 8 is located in the middle of the partition 4 .

[0043] In this embodiment, a cabinet door 12 is installed in the area on the right side of the partition 4 on the cluster cabinet 1 .

[0044] The working principle of the safety detection battery cluster cabinet of this utility model is as follows:

[0045] When the equipment is in operation, the liquid delivery pump 65 draws the cooled liquid into the water inlet pipe 62, and then enters the coils 61 installed on the top wall of each layer of the battery plug box 3. The coils 61 absorb heat and discharge the heated liquid into the water outlet pipe 63, and then into the water reservoir 64 for mixed cooling. The water reservoir 64 is fixed with multiple heat sinks 66, which extend out of the cluster cabinet 1 through the heat dissipation port for free ventilation and heat dissipation. When a fire occurs during equipment operation, the detector 51 detects an abnormality and converts it into an electrical signal to transmit to the controller 52. The controller 52 drives the motor to rotate according to the specific position of the detector 51, moves the nozzle 59 to the position where treatment is required, and opens the one-way solenoid valve 532 to extinguish the fire, thereby achieving the function of timely fire extinguishing.

[0046] 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.
