Description

Technical Field

[0001] The utility model relates to the field of energy storage, in particular to a BMS fire prevention diagnosis and early warning device for an energy storage station. Background Technique

[0002] In an energy storage power station system, hundreds of battery cells form an extremely complex system, which has highly non-linear, temperature-sensitive characteristics, obvious aging characteristics, and inconsistency in single-cell charging and discharging, etc. This also causes the battery pack to possibly experience thermal runaway due to the accumulation of heat released by its own chemical reactions or the influence of external heat sources, seriously affecting the safety performance of the energy storage power station; energy storage technology, as an important aspect of grid intelligence, its safe and reliable operation is related to the peak shaving and frequency modulation capabilities of the power grid, and is also a prerequisite for the safety of battery energy storage devices themselves.

[0003] A plurality of different types of fire detection sensors are arranged around the energy storage power station to monitor the operation of the energy storage power station. When a fire breaks out, inert gas is used for fire extinguishing; the abnormal detection of battery cells is conventionally completed through a battery management system (BMS). The BMS is installed in the energy storage battery pack and is responsible for collecting information such as voltage, temperature, current, and capacity of the energy storage battery pack, real-time status monitoring, and fault analysis. Due to the different application scenarios and application requirements of the energy storage power station on the grid side and the rapid iteration of technologies, in the prior art, the overall monitoring of the energy storage power station has insufficient accurate prediction ability and a high false alarm rate. When a thermal runaway occurs in the battery inside a single energy storage cabinet, it may not be detected or the detection and early warning pre-judgment are slow; while the BMS can only perform real-time detection of faults, it is difficult to capture the abnormal changes in detection variables in the next period of time, and it cannot pre-judge the occurrence of faults in advance. Moreover, traditional detectors have a late alarm time and low sensitivity, and can only alarm when the safety valve of the energy storage battery explodes or even smokes and catches fire, missing the best opportunity to handle the fire. Content of the Utility Model

[0028] Please refer to Figure 2 and Figure 3, in the illustrated sealing mechanism 3, it includes two support plates 301 symmetrically and fixedly installed on the top of the placement plate 2. On the side of the support plate 301 close to the fire extinguishing box 1, an L-shaped plate 302 is fixedly connected. At the corner of the L-shaped plate 302, a first sliding rod 303 is fixedly connected. At one end of the L-shaped plate 302 away from the support plate 301, a V-shaped folding rod 304 is provided.

On the side of the fire extinguishing box 1 close to the L-shaped plate 302, a guide plate 307 is fixedly connected. On the outer side of the guide plate 307, a first guide groove for the first sliding rod 303 and the third sliding rod 306 to be limited and slide is opened. On the outer side of the guide plate 307, a second guide groove for the second sliding rod 305 to be limited and slide is opened.

[0029] The pyroelectric ion sensor 8 detects the temperature of the energy storage battery 5. When the warning level is level five, the management module 6 starts the first motor 308. The first motor 308 drives the V-shaped folding rod 304 to rotate, so that the third sliding rod 306 on the V-shaped folding rod 304 moves along the first guide groove on the guide plate 307. At the same time, the second sliding rod 305 on the V-shaped folding rod 304 moves along the inner side of the second guide groove on the guide plate 307. The second sliding rod 305 can pull the L-shaped plate 302 to swing upward, and then can pull the placement plate 2 on the support plate 301 to swing upward synchronously, and drive the first sliding rod 303 to move along the first guide groove on the guide plate 307. Thus, the energy storage battery 5 on the placement plate 2 is put into the fire extinguishing box 1. The management module 6 starts the fire extinguishing module 7 to perform fire extinguishing treatment on the energy storage battery 5, thereby achieving the effect of quickly sealing and extinguishing the fire.

[0030] Please refer to Figures 2 - 6, the positioning mechanism 4 in the figure includes a mounting frame 401 fixedly installed at the bottom of the placement plate 2. Inside the mounting frame 401, two symmetrically distributed bidirectional screws 402 are rotatably installed. Sliders 403 are installed on the threads at both ends of the bidirectional screw 402. The sliders 403 cooperate with the bidirectional screw 402. Rotating the bidirectional screw 402 can drive the two sliders 403 to move in the same or opposite directions along the inner side of the mounting frame 401. A support rod 404 extending to the top of the placement plate 2 is fixedly connected to the top of the slider 403. A long strip groove for the support rod 404 to slide and be limited is provided at the top of the placement plate 2. A slide plate 405 is fixedly connected to the top of the support rod 404. A slide cavity for the slide plate 405 to slide and be limited is provided at the top of the placement plate 2. The width of the slide plate 405 is greater than the length of the long strip groove, which is used to block and seal the long strip groove. A pressing plate 406 is fixedly connected to the top of the slide plate 405. The pressing plate 406 has an L-shaped structure. The four pressing plates 406 are respectively located at the bottom corners of the energy storage battery 5 and are used to fix the energy storage battery 5.

[0031] Rotate the two bidirectional screws 402 to rotate synchronously, so that the bidirectional screw 402 drives the corresponding two sliders 403 to move closer along the inner side of the mounting frame 401. The support rod 404 drives the pressing plate 406 on the slide plate 405 to lean against the corners of the energy storage battery 5, thus achieving the effect of quick installation and improving the sealing stability of the energy storage battery 5.

[0032] Working principle: First, the user rotates two bidirectional screws 402 synchronously, causing the bidirectional screws 402 to drive the corresponding two sliders 403 to move closer along the inner side of the mounting frame 401.

The pyroelectric ion sensor 8 detects the temperature of the energy storage battery 5, calculates the impact caused by the temperature of the energy storage battery 5, and conducts five-level early warning management through five warning lights 9. The first-level early warning is used for information recording, the second-level early warning requires attention, the third-level early warning requires maintenance, the fourth-level early warning requires regular replacement, and the fifth-level early warning requires immediate handling. When the warning level is five, the management module 6 starts the first motor 308. The first motor 308 drives the V-shaped folding rod 304 to rotate, causing the third sliding rod 306 on the V-shaped folding rod 304 to move along the first guiding groove on the guiding plate 307. At the same time, the second sliding rod 305 on the V-shaped folding rod 304 moves along the inner side of the second guiding groove on the guiding plate 307. The second sliding rod 305 can pull the L-shaped plate 302 to swing upward, thereby pulling the placement plate 2 on the support plate 301 to swing upward synchronously and driving the first sliding rod 303 to move along the first guiding groove on the guiding plate 307. Thus, the energy storage battery 5 on the placement plate 2 is put into the fire extinguishing box 1. The management module 6 starts the fire extinguishing module 7 to conduct fire extinguishing treatment on the energy storage battery 5, thereby achieving the effect of rapid sealed fire extinguishing, realizing rapid and accurate prediction and early warning, and meeting the requirements of the energy storage power station system for early warning of faults and early actions. In practical applications, the pyroelectric ion sensor 8 in the fire prevention diagnosis and early warning device is connected to the BMS fire prevention system cloud platform, enabling the temperature information of the energy storage battery 5 detected by the sensor to be transmitted to the cloud platform in real time. The system can manage energy storage stations and energy storage facilities distributed in different geographical locations in the cloud to achieve joint defense.
