Description

Technical Field

[0001] This invention belongs to the field of safety protection devices for energy storage equipment, and specifically relates to a window-type safety protection device for energy storage that integrates pressure relief and fire protection. Background Technology

[0002] With strong government support for green energy, the energy storage industry has entered a period of rapid development. However, amidst this rapid growth, some energy storage battery devices (such as energy storage containers and integrated energy storage cabinets) are prone to thermal runaway due to safety design flaws and the inherent characteristics of lithium batteries. More importantly, the lack of comprehensive fire warning and extinguishing systems further amplifies the risk of fire after thermal runaway. In the event of a fire, firefighters often can only cool the equipment from the outside by spraying water, making precise and effective firefighting difficult, leaving them to wait for the equipment to burn itself out. Furthermore, spraying water to cool the equipment from the outside exposes firefighters to the constant risk of explosion, posing a serious threat to their lives.

[0003] Existing fire protection solutions for energy storage battery equipment, such as Figure 1 As shown, the system combines water-based fire suppression (fire hoses 1 are installed on the top and sides of the container, open fire sprinklers 2 are evenly distributed on the fire hoses 1, and a DN65 interface 3 at one end of the fire hoses 1 is fixed to the side of the container; the entire container is spray-painted) with an explosion relief plate 4. The principle is that the explosion relief plate is used to release high-pressure gas inside the energy storage equipment (container), and water spraying is used to cool the inside of the equipment after the water-based fire suppression is connected. The disadvantage of this method is that firefighters need to manually connect the fire hose interface to the DN65 interface on the equipment at close range, which poses a risk to the personal safety of the firefighters.

[0014] Further comprising an electrical control system and a sensor detection device arranged inside the energy storage device box, for controlling the opening state of the pressure relief fire water inlet structure through the electrical control system according to the environmental information obtained by the sensor detection device.

DETAILED DESCRIPTION

[0029] The structure and working process of the present application will be further described below with reference to the accompanying drawings.

[0030] The purpose of the present application is to solve the problems in the prior art, and develop a pressure relief and fire-fighting integrated window. The window can meet the exhaust demand when the energy storage battery equipment is in thermal runaway, and also enable the fire fighters to effectively extinguish the fire at a safe distance away from the equipment on fire. The working logic is as follows: when the internal gas pressure of the equipment reaches the preset exhaust threshold, the pressure relief and fire-fighting integrated window is passively opened for exhaust; and when the equipment is on fire, the fire fighters do not need to approach the equipment on fire, but only need to spray water on the fire-fighting special window of the pressure relief and fire-fighting integrated window, so as to open the fire-fighting special window, inject water into the equipment on fire, and complete the efficient immersion extinguishing. This design not only ensures the safety of the fire fighters, but also achieves the goal of effective fire extinguishing.

[0032] Specific embodiments are shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 as shown in

[0033] A pressure relief and fire-fighting integrated window structure, comprising a window body 5 fixedly arranged, and a window panel movably connected with the window body 5, the window panel has a bidirectional opening and closing state relative to the window body, which is a pressure relief and exhaust state and a fire-fighting water injection state respectively; wherein the pressure relief and exhaust state is that the window panel is opened from the inside to the outside, and the fire-fighting water injection state is that the window panel is opened from the outside to the inside. The window panel comprises two parts, one part is a quadrilateral frame 6, and the other part is a baffle assembly 7 matched with the quadrilateral frame. The quadrilateral frame 6 is arranged on the outside of the window body, and the baffle assembly 7 is arranged on the inside of the quadrilateral frame.

[0034] The baffle assembly 7 is provided with a pressure sensor 7-3 fixed by a fixed support 7-6 and a screw 7-7. The outside 7-1 of the baffle is a force receiving plate of the pressure sensor. The force receiving plate 7-1 penetrates the inside 7-2 of the baffle and a baffle anti-loose spring 7-5, is fixed by a baffle fixing nut 7-4, and the baffle anti-loose spring 7-4 can make the force receiving plate 7-1 tightly adhere to the pressure sensor 7-3. A motor 7-11 is fixed on the quadrilateral frame 6, and opens the baffle through a rope 7-10, a rope support 7-9, and a rope fixing point 7-8 on the inside 7-2 of the baffle. The inside 7-2 of the baffle is connected with the quadrilateral frame through a hinge 7-12.

[0035] The pressure relief and fire-fighting integrated window can be applied to an energy storage container. The specific design and application principle are as follows:

[0036] 1、When the battery pack in the container produces thermal runaway, a large amount of flammable gas will be sprayed from the battery pack pressure relief port, the volume of the gas discharged from the battery pack is , the net volume of the container is , at this time the pressure generated by the volume of the gas discharged from the battery pack on the inner wall of the container is , then , so , wherein is the standard atmospheric pressure.

[0037] 2、The opening pressure of the pressure relief port on the container is , then when , the pressure relief port on the container opens outward.

[0038] 3、The pressure relief port opens, the gas in the container is discharged, the pressure drops, and the pressure relief port closes due to gravity and magnetic attraction.

[0039] 4、The pressure at which the fire window on the pressure relief port opens from the outside to the inside is ;

[0040] 5、When the firefighter (or the person in charge of fire safety on the scene) arrives at the scene, the fire safety device is activated, the fire nozzle sprays water towards the pressure relief port, and the pressure sensor on the fire window receives a pressure value exceeding , the motor receives a signal to start, and opens the fire window through a rope. When the pressure sensor and the motor fail, when the pressure relief port is subjected to the pressure generated by the water flow from the outside , then when , the fire window on the pressure relief port can also be passively opened.

[0041] 6、The fire window in this embodiment opens downward and cannot be automatically reset once it is opened. It needs to be manually reset.

[0042] In order to further illustrate the application of the pressure relief and fire safety integrated window described above, the present application also discloses a pressure relief and fire safety system, as shown in Figure 6 , Figure 7 , comprising an energy storage device box body, a plurality of pressure relief and fire safety integrated windows 8 are arranged on the side wall of the energy storage device box body, and are used to automatically open under the action of internal or external force when the energy storage device box body needs to be relieved or extinguished. 9 battery and 10 fire flow.

[0043] The pressure relief and fire safety integrated window of the pressure relief and fire safety system is arranged at the position close to the upper part of the side of the energy storage device box body, and the number and arrangement thereof are arranged according to the following rules:

[0044] Each cluster of battery packs (a row) is equipped with a pressure relief and fire safety integrated window, which is installed at the upper part of the side of the box body or the door.

[0045] When a fire occurs causing the internal air pressure to rise greater than the threshold for opening the pressure relief port The pressure relief port will automatically open to vent air; after the air is vented, the pressure relief port will close under the force of gravity, and the bottom magnet will then attract the pressure relief port, restoring the seal.

[0046] In a fire emergency, firefighters can use a fire hose or cannon in a safe area to spray the fire port on the pressure relief fire integrated window. At this time, the pressure sensor on the fire port will monitor the pressure value in real time: when the external pressure of the fire port reaches the preset threshold , the system will start the motor to open the fire port, allowing water to flow into the box through the fire port. Even in the event of a pressure sensor or motor failure, when the external water pressure reaches , the fire port will be passively opened by the magnetically fixed fire port. After the box is filled with water, immersion fire extinguishing can be achieved.

[0047] The core innovation of the pressure relief fire integrated window and its application is that firefighters do not need to be close to the dangerous box to inject water into the box, and do not need to wait.

[0048] Compared with the traditional solution: in the case that the fire-fighting system inside the box does not work, the traditional solution needs to wait for the complete burning of the box or for firefighters to risk approaching the box to connect the fire hose to the fire pipe on the box to allow water to flow into the box and achieve immersion fire extinguishing.
