Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, specifically to an aerosol fire extinguishing feedback device. Background Technology

[0002] Energy storage systems are comprehensive solutions that temporarily store energy (such as electricity and heat) using specific technologies and release it on demand. They are widely used in scenarios such as mitigating the fluctuations in renewable energy sources like photovoltaics and wind power, peak shaving and valley filling in the power grid, peak-valley arbitrage for users, and emergency backup power. However, energy storage systems pose significant safety risks, especially frequent fires. Lithium battery thermal runaway and electrical equipment failures are the main causes of fires at energy storage stations, and these fires are characterized by rapid spread and difficulty in extinguishing.

[0003] Traditional firefighting methods often fall short in the face of the "chain reaction" of thermal runaway in lithium batteries. Air cooling is inefficient, gas extinguishing systems are ineffective at preventing reignition, and the lack of intelligent early warning systems means that risks are often only detected after the fire has started, leading to further escalation. Aerosol fire suppression technology, due to its advantages such as high extinguishing efficiency, environmental friendliness, and the absence of complex piping structures, shows promising application prospects in fire protection for energy storage systems. However, most existing aerosol fire suppression devices are passively activated, lacking the ability to perceive and respond to the real-time fire situation. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, in one embodiment, an aerosol fire extinguishing feedback device includes: an aerosol generating component 1 and a signal feedback component 3;

[0028] Among them, the aerosol generating component 1 initiates a chemical reaction through an internal activation mechanism to directionally release fire extinguishing aerosols; while signal feedback components 3 are symmetrically installed on the outside of the aerosol generating component 1 through the connector 2, which are used to accurately capture and provide real-time feedback of the release status signal after the aerosol generating component 1 completes the release action.

[0029] Furthermore, the aerosol generating component 1 includes a main body box 11, which is made of high-strength corrosion-resistant material and has a special internal sealing treatment, which can provide a stable storage environment for the aerosol generating agent, effectively isolate external moisture, dust and other interfering factors, and ensure that the extinguishing agent has stable performance within its shelf life.

[0030] Specifically, the main body box 11 has a mounting slot 12 in the middle to accommodate the signal feedback component 3, which matches the connection part of the signal feedback component 3 and enables quick positioning and installation; correspondingly, the bottom of the main body box 11 is provided with a mounting platform 13, which has pre-set standardized bolt holes to firmly fix the entire aerosol generating component 1 in the target installation position, ensuring the structural stability of the equipment under long-term use and vibration environment.

[0031] For example, the overall dimensions of the aerosol generating component 1 are controlled within a compact range of 133×54mm, with a total weight of only 1300g, making it easily adaptable to various confined installation spaces; it contains 300g of high-efficiency aerosol generator, and based on the type of combustible material and space volume of the protected area, it can achieve a range of 2.4-6.9m. 3 It provides total flooding fire suppression coverage for protected spaces; the aerosol release process is precisely controlled within 20 seconds to ensure rapid suppression of initial fires; and the operating temperature range covers -40℃ to 75℃, adapting to energy storage scenarios in extreme high and low temperature environments.

[0032] Understandably, aerosol fire extinguishing technology is a new type of fire protection technology developed for civilian use based on military pyrotechnics technology. It has high fire extinguishing efficiency, interrupting the combustion chain reaction through the dual effects of physical coverage by ultrafine particles (usually less than 1μm in diameter) and chemical inhibition by inert gases (such as nitrogen and carbon dioxide). During installation, it does not require complex pipelines and high-pressure containers, only simple brackets for fixation, which greatly reduces the difficulty of construction. It has a long shelf life and extremely low daily maintenance costs. Its compact design can save a lot of space in the protected area. The released aerosol can form a stable residence in non-enclosed spaces (the residence time is usually more than 30 minutes), which effectively solves the technical pain points of rapid agent leakage and fire extinguishing failure of traditional high-pressure gas fire extinguishing systems in non-enclosed environments. Therefore, it is widely used in semi-open scenarios such as energy storage battery boxes.

[0033] Furthermore, the connector 2 is fitted into the mounting groove 12, which can lock and fix the aerosol generating component 1 and the signal feedback component 3.

[0034] For example, the connector 2 is a clamp, which has good corrosion resistance and structural strength, and is adapted to the cylindrical or square shape of the main body box 11. The diameter can be finely adjusted by adjusting the bolts to meet the assembly tolerance requirements of different batches of equipment.

[0035] It is understandable that radial locking can be achieved by tightening the bolts on the clamp, thus locking the aerosol generating component 1 and the signal feedback component 3 together to ensure that there is no relative displacement between the two during equipment operation and vibration.

[0036] Furthermore, the signal feedback component 3 includes a bent part 31, the side of which is in close contact with the outer periphery of the main body box 11 to form a stable mechanical limit and prevent the feedback component from sliding axially during installation or use.

[0037] Specifically, the bottom length of the bent component 31 is greater than the height of the mounting platform 13, ensuring that the bent component 31 is not interfered with by the support of the mounting platform 13 after the equipment is installed, so that its sensing end can be fully exposed to the heat field of the aerosol spray, ensuring the accuracy of temperature sensing.

[0038] Correspondingly, a feedback module 32 is installed at the end of the bent component 31. The feedback module 32 is electrically connected to the fire monitoring system through a high-temperature resistant cable to form a signal transmission path.

[0039] For example, the core temperature control contact of the feedback module 32 is set to operate at 125°C. This temperature threshold is higher than the normal operating temperature of the energy storage device (typically ≤60°C) and lower than the critical temperature for fire spread (typically ≥150°C), which can effectively prevent false triggering while ensuring timely response.

[0040] It should be explained in detail that the bending part 31 is perpendicular to the axis of the main body box 11: that is, before installing the aerosol generating component 1, carefully check the sealing performance of the main body box 11 to ensure that there is no damage to the appearance and that all parts are complete; then, according to the design plan and the actual situation of the protected area, select a suitable installation position, and use bolts and other connecting parts 2 to install the aerosol generating component 1 in a suitable position on the energy storage box, ensuring that the bracket is firm and reliable; then, according to the sensing requirements of the signal feedback component 3, mark the installation height and position of the clamp on the aerosol generating component 1; finally, wrap the clamp and the signal feedback component 3 horizontally around the aerosol body, ensuring that they are perpendicular to the axis of the equipment and avoiding tilting that could cause slippage.

[0041] Understandably, when the aerosol extinguishing agent reacts to produce aerosol extinguishing agent and is sprayed into the protected area, the signal feedback component 3 gradually heats up. When the temperature sensing temperature of the temperature control contact of the feedback module 32 reaches the 125°C trigger threshold, the internal metal sheet deforms, causing the contact to close and forming an electrical signal path. This transmits the status signal of the extinguishing device being activated to the fire control system in real time, enabling the monitoring center to promptly grasp the operation status of the extinguishing device and provide a basis for subsequent operations such as activating audible and visual alarms, cutting off the area power supply, and linking other extinguishing equipment.

[0042] Through the above technical solution, the aerosol fire extinguishing feedback device of this application is compact in size and can be ceiling-mounted. After the aerosol is released, it transmits the release signal to the monitoring system by sensing the temperature, so as to promptly remind the operation and maintenance personnel of the fire extinguishing action in the energy storage box, effectively avoid personnel from accidentally entering the dangerous area that is not fully controlled, and significantly improve the safety and reliability of fire monitoring of energy storage equipment.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
