Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fire safety, especially to a fire-fighting system of energy storage cabinet. BACKGROUND

[0002] The energy storage cabinet is a device that can store electrical energy, usually composed of battery packs, converters, control chips and other parts. It can store electrical energy and release it when needed for power use, usually used to provide backup power and stabilize grid voltage. Energy storage cabinet can suppress the fluctuation caused by non-connectivity new energy access to power grid, maintain the stability of power grid, and also can suppress load jump, play the role of frequency modulation and voltage regulation, and improve power factor.

[0003] In the use process of the energy storage cabinet, common faults include: 1. Battery failure: battery aging, overcharging and overdischarging, internal short circuit, etc. may cause battery failure, in addition, the performance decline or damage of individual battery in the battery pack may also affect the performance of the entire battery pack; 2. Electrical fault: such as overcurrent, overvoltage, undervoltage, insulation fault, etc., which may cause equipment damage or safety problems; 3. Mechanical failure: such as impact, vibration, etc. of the energy storage cabinet, which may cause mechanical component damage or looseness; 4. Environmental influence: such as extreme temperature, humidity, corrosion, etc. environmental factors may also affect the performance and safety of the energy storage cabinet; 5. Design and manufacturing defects: defects in the design and manufacturing process of the energy storage cabinet may also cause failure.

[0004] When the above-mentioned faults occur, it is easy to cause the entire energy storage cabinet to burn, and the temperature during combustion is high and the fire is large, which is easy to ignite surrounding objects. The existing fire-fighting system for energy storage cabinet is not perfect, which leads to safety hazards of the energy storage cabinet.

[0005] In the prior art (publication number: 2024.04.09, publication date: CN220753627U), a new energy battery energy storage cabinet is disclosed. When the new energy battery energy storage cabinet is in use, the new energy battery is placed in the battery placing groove. When the energy storage cabinet body catches fire, the sensor on the nozzle in the energy storage cabinet body senses the fire signal. At this time, the signal is fed back to the signal feedback device, and the signal feedback device controls the working of the fire extinguishing agent bottle group to transport the fire extinguishing foam into the energy storage cabinet body through the main pipe and the fire extinguishing pipeline to extinguish the fire in the energy storage cabinet body. Since the energy storage cabinet body is a frame structure and has gaps, the gas fire extinguishing agent can be quickly diffused into the energy storage cabinet body during extinguishing to extinguish the fire in the energy storage cabinet body, ensuring the safety of the new energy battery during placement or charging in the cabinet.

[0006] However, the above-mentioned scheme still has the following defects in the fire extinguishing process:

[0007] 1. The extinguishing agent will spread throughout the entire energy storage cabinet, which will have a certain impact on the battery packs that are not faulty. In addition, the extinguishing agent cylinders need to be inspected and replaced regularly to ensure that the fire can be extinguished in time when it occurs.

[0008] 2. The energy storage cabinet cannot provide heat dissipation for the internal battery pack when it is working. The battery pack will get very hot when it works for a long time, which will increase the probability of failure.

[0009] 3. This solution requires timely power disconnection during firefighting. However, the battery pack stores electrical energy, which will accelerate the burning speed of the battery pack, making it difficult to extinguish the fire in time. Utility Model Content

[0047] As Figures 1-11 The utility model discloses a kind of fire-fighting systems of energy storage cabinet 1, including the energy storage cabinet 1 and control cabinet 2 of split setting;

[0048] The energy storage cabinet 1 is installed with several battery compartments 3, several battery compartments 3 are independently separated and arranged, and a plurality of battery cells 4 are fixedly installed in the battery compartment 3, a heat dissipation inlet 5 is formed on one side of the battery compartment 3, a heat dissipation outlet 6 is formed on the other side of the battery compartment 3, a heat dissipation pipeline 7 is connected at the heat dissipation inlet 5, and an air pipe 8 and a liquid pipe 9 are connected to the outer end of the heat dissipation pipeline 7.

[0049] The air pipe 8 blows and dissipates heat to the battery cell 4 in the battery compartment 3 through the heat dissipation pipeline 7, the liquid pipe 9 fills the fire-retardant electrolyte in the battery compartment 3 through the heat dissipation pipeline 7, and the battery cell 4 in the battery compartment 3 is electrically connected to the battery compartment 3 through the fire-retardant electrolyte for grounding connection.

[0050] The fire-fighting valve 10 is connected between the air pipe 8, the liquid pipe 9 and the heat dissipation pipeline 7, the sensor 11 is installed in the battery compartment 3, and the control cabinet 2 controls the fire-fighting valve 10 to work through the sensor 11.

[0051] The principle is: using the battery compartment 3 arranged separately, when the battery cell 4 in a certain battery compartment 3 fails, the fire-retardant electrolyte can be filled in the battery compartment 3 alone to extinguish the fire in the battery compartment 3, and the battery compartment 3 without failure will not be affected;When used normally, the air pipe 8 blows and dissipates heat to the battery cell 4 in the battery compartment 3 through the heat dissipation pipeline 7, which can take away the heat of the battery cell 4 working for a long time and output from the heat dissipation outlet 6, thereby reducing the heat of the battery cell 4 working and reducing the occurrence of failure;When the battery cell 4 in a certain battery compartment 3 fails, the liquid pipe 9 fills the fire-retardant electrolyte in the battery compartment 3 through the heat dissipation pipeline 7, because the fire-retardant electrolyte has the characteristics of conductivity and fire resistance, so it can effectively extinguish the fire, and the electric quantity stored in the battery cell 4 is connected to the battery compartment 3 for grounding through the fire-retardant electrolyte, realizing rapid discharge, thereby improving the fire extinguishing efficiency.

[0052] When the battery cell 4 experiences malfunctions such as overheating, smoke, or fire, this invention can promptly inject flame-retardant electrolyte into the corresponding battery compartment 3. The flame-retardant electrolyte has flame-retardant and conductive properties, allowing the battery cell 4 to extinguish the fire quickly. At the same time, the battery cell 4 can also quickly discharge to the ground, thereby providing safety assurance for the energy storage cabinet.

[0053] Furthermore: the fire valve 10 includes a positioning tube 101, a water-resistant glass baffle 102, an impact pin 103, a sealing plate 104, a waterproof gasket 105, and a pneumatic cylinder 106. The water-resistant glass baffle 102 is fixedly installed at the lower end of the liquid pipe 9. The positioning tube 101 is fixedly installed at the bottom side of the water-resistant glass baffle 102. The air pipe 8 and the heat dissipation pipe 7 are respectively connected to the outside of the positioning tube 101. The sealing plate 104 and the waterproof gasket 105 are both fixedly installed at the bottom end inside the positioning tube 101. The impact pin 103 is installed in the middle of the sealing plate 104 and the waterproof gasket 105. The pneumatic cylinder 106 is fixedly installed at the bottom end of the positioning tube 101, and the pneumatic cylinder 106 drives the impact pin 103 to rise rapidly against the water-resistant glass baffle 102. 02 Impact occurs. Control cabinet 2 controls the pneumatic cylinder 106 inside the fire valve 10 to work through sensor 11. When sensor 11 detects a malfunction in battery compartment 3, control cabinet 2 can control the corresponding pneumatic cylinder 106 to open. When pneumatic cylinder 106 opens, it will drive the impact pin 103 to rise rapidly and impact the water-resistant glass baffle 102, thereby breaking the glass. Similar to the principle of a piston, after the glass is broken, the flame-retardant electrolyte will not leak at the bottom of the positioning tube 101. The flame-retardant electrolyte in the liquid pipe 9 is poured into battery compartment 3 through heat dissipation pipe 7. Since the pressure of hydraulic pressure is greater than that of air pressure, the airflow in the air pipe 8 can be blocked when the flame-retardant electrolyte is delivered, so as to achieve rapid fire extinguishing and grounding discharge.

[0054] Furthermore, the fire valve 10 also includes a conical filter screen 107, which is installed in the positioning tube 101 with a clearance fit. The liquid in the liquid pipe 9 is filtered by the conical filter screen 107 and then transported to the heat dissipation pipe 7. The conical filter screen 107 can block broken glass and prevent glass from entering the battery compartment 3.

[0055] Furthermore: A magnetic guide frame 12 is fixedly installed at the lower end of the positioning tube 101, and a cylinder body bracket 13 is fixedly installed on the outside of the pneumatic cylinder 106. A neodymium magnet 14 is embedded in the cylinder body bracket 13, and the neodymium magnet 14 is magnetically attached to the magnetic guide frame 12. The pneumatic cylinder 106 can be installed on the magnetic guide frame 12 using the neodymium magnet 14. When the pneumatic cylinder 106 fails, it can be quickly disassembled, and flame-retardant electrolyte can be poured into the faulty battery compartment 3 by manual tapping. It has both automatic and manual modes to achieve rapid fire extinguishing and grounding discharge.

[0056] Further, the battery compartment 3 comprises a compartment body 31 and an upper cover 32, the upper cover 32 is a water-cooled heat dissipation plate, a water-cooled pipe 33 is arranged and mounted in the upper cover 32, the two ends of the water-cooled pipe 33 are respectively connected with a water inlet 15 and a water outlet 16, a water inlet pipe 17 and a water outlet pipe 18 are fixedly installed on the outside of the energy storage cabinet 1, the water inlet pipe 17 is connected with the water inlets 15 of the plurality of battery compartments 3, and the water outlet pipe 18 is connected with the water outlets 16 of the plurality of battery compartments 3; during normal operation, the air pipe 8 blows air to the battery compartment 3 through the heat dissipation pipe 7, and the water-cooled heat dissipation plate uses a water-cooled mode to quickly take away the heat generated by the battery compartment 3 during operation, thereby improving the heat dissipation effect and reducing the hidden danger of failure of the battery cell 4.

[0057] Further, the sensor 11 is a temperature detector, and the sensor 11 is provided with one or more sensors installed in the battery compartment 3; the temperature in the battery compartment 3 can be detected in real time, and when the detected temperature is greater than a specified temperature, it is judged that the battery compartment 3 has failed, and the corresponding pneumatic cylinder 106 is opened in time, and then the fire extinguishing and grounding discharge of the fire extinguishing electrolyte are carried out in the battery compartment 3 which has failed.

[0058] Further, a smoke alarm 19 is fixedly installed at the upper end of the energy storage cabinet 1, and the smoke alarm 19 and the control cabinet 2 are electrically connected with each other; when smoke is generated, the smoke alarm 19 can timely remind personnel to check, so as to facilitate the suppression of fire.

[0060] Further, a plurality of liquid inlet holes 22 are formed on the bottom side of the battery equalizer 20, when the liquid pipe 9 delivers liquid into the battery compartment 3 through the heat dissipation pipe 7, part of the fire-retardant electrolyte enters the battery equalizer 20 through the liquid inlet holes 22 to make the wires connected with the battery cells 4 grounded; when a failure occurs, the fire-retardant electrolyte can be used to realize rapid grounding discharge due to its conductive property, thereby effectively suppressing the fire.

[0061] Further, the plurality of battery cells 4 in the battery compartment 3 are arranged parallel to and apart from each other, the plurality of heat dissipation inlets 5 are arranged in an equidistant array, the shunt pipe 23 is connected between the heat dissipation pipe 7 and the plurality of heat dissipation inlets 5, and the air pipe 8 is arranged to blow air to the gaps between the plurality of battery cells 4 in the battery compartment 3 through the heat dissipation pipe 7 and the shunt pipe 23.
