Description

Technical Field

[0001] The utility model relates to the field of energy storage, and more specifically, to a fire protection system of an integrated energy storage machine. Background Art

[0002] Energy storage equipment is an important supporting device for new energy products, and can also balance the fluctuation difference between peak and valley electricity. Energy storage batteries are generally loaded with several battery modules in the form of cabinets, and the battery modules have several battery cells, so as to achieve intensive loading and centralized management of batteries. However, the centralized placement of these high-energy objects also creates a strong need for fire safety.

[0003] At present, energy storage cabinets generally use a medicine bottle to connect to a spray pipe, and the other end of the spray pipe is connected to a fire nozzle, and the signal transmitted by the fire signal sensor controls the opening and closing of the pipeline. The disadvantage of this method is that each module needs to add an additional fire signal sensor and fire nozzle to control the spraying of a single module. The increase in the number of sensors and the special design of the nozzle increase the cost of the fire protection system.

[0004] Therefore, there is a related technology that uses a fire-detecting tube that can break when encountering fire and extends into the battery module. When encountering fire, it will automatically break, and the fire extinguishing agent can flow out from the rupture to extinguish the fire. This form can save a large number of sensors, reduce the difficulty of designing the fire protection system and the difficulty of building the device. However, the existing fire-detecting tube fire protection form often uses a single pipeline. After a fire occurs in a battery module, the pressure in the rear section will decrease, resulting in the battery module adjacent to the battery module being in a high temperature environment, but the amount of fire extinguishing agent and the flow rate of fire extinguishing agent that can be obtained are insufficient.

[0005] In view of this, the present application aims to provide a fire protection system for an integrated energy storage device, providing multiple fire extinguishing agent pipelines to provide sufficient fire extinguishing agent protection for adjacent locations of battery modules where fire occurs, thereby ensuring that the danger does not spread. Summary of the invention

[0006] The utility model overcomes the problem that the existing fire detection pipe-fire protection system adopts a single pipeline. After a fire occurs in a battery module, the pressure in the rear section will decrease, resulting in the battery modules adjacent to the battery module being in a high temperature environment, but the amount of fire extinguishing agent and the flow rate of fire extinguishing agent that can be obtained are insufficient. A fire protection system of an energy storage integrated machine is provided, which provides multiple fire extinguishing agent pipelines to provide sufficient fire extinguishing agent protection for the adjacent positions of the battery module where the fire occurs, thereby ensuring that the danger does not spread.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A fire protection system of an energy storage integrated machine, the energy storage integrated machine includes a battery compartment, the fire protection system includes a medicine bottle, a medicine delivery tube and a fire detection tube, the battery compartment has an energy storage rack, the energy storage rack has a plurality of cabinets along the height direction, the cabinet is a battery management system and a plurality of battery modules, the fire detection tube is located in the cabinet, the cabinet has a medicine inlet port,

[0009] The medicine delivery pipe includes a medicine delivery main pipe, several medicine delivery branch pipes and a series pipe. The medicine delivery main pipe is connected to the medicine delivery branch pipes respectively, the medicine delivery branch pipes are connected to the series pipes, and the series pipes are connected to the medicine inlet ports of the cabinets arranged at intervals.

[0010] The fire fighting form of the present application is to provide fire extinguishing agent and pressure to the pipeline structure composed of the medicine delivery pipe and the fire detection pipe through the medicine bottle, and the pressure delivers the fire extinguishing agent. It automatically breaks at the high temperature point, and the medicine flows out from the rupture hole caused by the rupture of the fire detection pipe to cool down the high temperature position and extinguish the fire. The material of the fire detection pipe is common knowledge in the field of fire protection, and it can be purchased and applied quite easily on the market. The principle of its high temperature rupture is not within the scope of application of this application. The medicine delivery branch pipe constitutes multiple pipelines through series pipes, and the cabinets connected by multiple pipelines are not repeated. One medicine delivery branch pipe is connected to a cabinet, and the other medicine delivery cabinet is connected to the cabinet on the upper side and / or the lower side of the cabinet to provide it with fire extinguishing agent. In this way, when the cabinet is out of control and the high temperature destroys the fire detection pipe, the fire extinguishing agent flows out or is discharged continuously through the corresponding medicine delivery branch pipe to extinguish the fire, and the gas or liquid pressure in the medicine delivery branch pipe is reduced. Due to the close physical distance to the cabinet, the temperature of the adjacent cabinet is high, and there is also a high risk of fire detection pipe rupture. By setting up multiple medicine delivery pipes, sufficient fire extinguishing agent pressure can be provided, so as to ensure that the corresponding cabinet can discharge sufficient fire extinguishing agent after the fire detection pipe ruptures. Since it is impossible to predict which cabinet will be the first to cause a fire hazard, a series pipe connected to the medicine delivery pipe is set to connect the cabinets set at intervals, so that if any cabinet is in danger, the medicine delivery pipes connected to the adjacent cabinets are not the same as the medicine delivery pipes connected to the cabinet that caused the danger.

[0011] Preferably, each medicine delivery branch pipe is connected to the same position of the medicine delivery main pipe, and the pressure in each medicine delivery branch pipe is the same. The above structure enables each medicine delivery branch pipe to evenly distribute the flow.

[0012] Preferably, there are two medicine delivery sub-branches, including a first medicine delivery sub-branches and a second medicine delivery sub-branches, wherein the first medicine delivery sub-branches are connected to cabinets at odd positions on the energy storage rack, and the second medicine delivery sub-branches are connected to cabinets at even positions on the energy storage rack. From low to high, the cabinets include cabinet No. 1, cabinet No. 2, ... the first medicine delivery sub-branches and the second medicine delivery sub-branches are connected to cabinets with odd numbers and even numbers, so that the medicine delivery sub-branches connected to any cabinet are not the same as the medicine delivery sub-branches connected to the adjacent cabinets.

[0013] Preferably, a solenoid valve is provided on the medicine delivery pipe, which controls the on and off of the medicine delivery pipe, and is electrically connected to the battery management system. Under normal temperature conditions, the battery management system controls the solenoid valve to be in a closed state, reducing the pressure of the medicine delivery pipe and the fire detection pipe, thereby extending the life of the medicine delivery pipe and the fire detection pipe; further, in order to avoid the problem of failure of the battery management system due to high temperature, the solenoid valve is a normally open solenoid valve.

[0014] Preferably, the series pipe includes a three-way pipe, the three pipe openings of the three-way pipe are respectively connected to the medicine inlet port, the three-way pipes on the upper and lower sides or the medicine delivery branch pipe, and the pipe opening on the upper side of the top three-way pipe is closed. The series pipe, the fire detection pipe and the medicine delivery branch pipe are connected by the structure.

[0015] Preferably, the fire detection tube is arranged in a serpentine shape inside the battery module. Since cracks can be formed at various places of the fire detection tube, more battery cells in the battery module can be covered by the serpentine arrangement, and the battery cells generating high temperature can be directly cooled by delivering medicine.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) each fire detection tube is extended into the battery module one by one, and the fire of the battery module is accurately extinguished, thereby reducing the pre-installed amount of fire extinguishing agent; (2) the use of fire detection tubes instead of fire sprinkler heads plus sensors reduces costs; (3) multiple fire extinguishing agent pipelines are provided, and the medicine inlet ports of the cabinets arranged at intervals are connected by series pipes, so as to provide sufficient fire extinguishing agent for the adjacent positions of the battery module where the fire occurs, thereby ensuring that the dangerous situation does not spread.

In some embodiments, the number of the medicine delivery branch pipes 9 is two, and the medicine delivery branch pipes 9 include a first medicine delivery branch pipe 11 and a second medicine delivery branch pipe 12, the first medicine delivery branch pipe 11 is connected to the cabinets at odd positions on the energy storage rack 4, and the second medicine delivery branch pipe 12 is connected to the cabinets at even positions on the energy storage rack 4. From low to high, the cabinets include cabinet No. 1, cabinet No. 2, ... The first medicine delivery branch pipe 11 and the second medicine delivery branch pipe 12 connect the odd-numbered and even-numbered cabinets, so that the medicine delivery branch pipe 9 connected to any cabinet is not the same as the medicine delivery branch pipe 9 connected to the adjacent cabinet. Each medicine delivery branch pipe 9 is connected to the same position of the medicine delivery main pipe 8, and the pressure in each medicine delivery branch pipe 9 is the same. The above structure enables each medicine delivery branch pipe 9 to evenly distribute the flow.

[0029] The series pipe 10 includes a three-way pipe 13 and a connecting pipe 14. The three pipe openings of the three-way pipe 13 are respectively connected to the medicine inlet port 7, the three-way pipes 13 on the upper and lower sides or the medicine delivery branch pipe 9, and the pipe opening on the upper side of the top three-way pipe 13 is closed.

[0030] Ginseng Figure 2 As shown, the fire detection tube is arranged in a serpentine shape inside the battery module. Since cracks can be generated at various locations of the fire detection tube, more battery cells in the battery module can be covered by the serpentine arrangement, and the battery cells generating high temperatures can be directly cooled by delivering medicine.

It automatically breaks at the high temperature point, and the medicine flows out from the rupture hole caused by the rupture of the fire detection pipe 3 to cool down the high temperature position and extinguish the fire.
