Description

Technical Field

[0001] This utility model relates to the field of waste battery management technology, and in particular to a monitoring system for waste battery storage equipment. Background Technology

[0002] With the rapid development of the new energy industry and the power sector, the generation of waste lithium batteries and lead-acid batteries has increased dramatically. These waste batteries contain heavy metals such as mercury, lead, and cadmium, as well as highly corrosive electrolytes. During storage, there is a risk of leakage, which could lead to soil and groundwater pollution, and the release of hydrogen gas (…). ), methane ( ), hydrogen fluoride ( Flammable, explosive, and toxic gases are more likely to accumulate, causing fires, explosions, or poisoning accidents, seriously threatening the safety of people's lives and property.

[0003] Currently, traditional waste battery storage facilities have significant drawbacks: 1. Most facilities are equipped with only a single smoke or temperature alarm, with each sensor operating independently, making it impossible for the system to perform correlation analysis of multiple parameters. This leads to a high false alarm rate (e.g., dust triggering smoke detection) and insensitivity to slowly developing hazards (e.g., early thermal runaway), failing to provide early warning. 2. Existing systems typically employ a simple threshold mode of "alarm when exceeding limits," relying on manual judgment and handling after an alarm, resulting in slow response and a lack of automated hierarchical response and linkage control mechanisms, making it difficult to effectively curb the escalation of accidents. 3. Storage equipment lacks holistic design, with insufficient consideration given to leakage collection, ventilation and purification, and convenient access. Furthermore, management methods are rudimentary, failing to achieve remote data monitoring, historical tracing, and intelligent analysis, resulting in high operation and maintenance costs and low efficiency.

[0004] Therefore, the development of a monitoring system for waste battery storage devices that integrates intelligent monitoring, precise early warning, automatic linkage, and remote management is increasingly urgent to improve storage safety, prevent environmental risks, and achieve refined management.

[0023] The battery storage module, connected to the data acquisition module, is equipped with an early warning device and is used to store used batteries.

[0024] The monitoring and control module is connected to the data acquisition module and the battery storage module to acquire relevant monitoring data. When the detected relevant monitoring data reaches the preset comprehensive risk index, the monitoring and control module triggers the action of multi-level early warning devices. The actions of the early warning devices include activating audible and visual alarms, turning on ventilation equipment for ventilation, and cutting off the power supply.

[0025] The user terminal module connects to the monitoring and control module via a communication interface to enable the viewing, statistics, recording, and transmission of detection data.

[0026] This embodiment collects multi-source data through a data acquisition module, and the monitoring and control module acquires relevant monitoring data. When the detected relevant monitoring data reaches the preset comprehensive risk index, the monitoring and control module triggers the early warning device to act, establishing a multi-level early warning mechanism. It is then connected to the user terminal module for implementation, enabling the viewing, statistics, recording, and transmission of detection data. This overcomes the limitations of single-sensor monitoring, effectively distinguishes between real threats and environmental interference, greatly reduces the false alarm rate, improves the accuracy of safety management, reduces the intensity of manual inspections and safety hazards, and achieves efficient remote, intelligent, and visualized management, effectively reducing operation and maintenance costs.

[0027] In the preferred solution, such as Figure 5 As shown, the battery storage module includes a battery storage box, the internal space of which is divided into four independent compartments.

Different levels trigger differentiated response measures, ranging from automatically activating ventilation and purification equipment to triggering audible and visual alarms, reporting to the fire control room, and even emergency power cut-off or activation of fire extinguishing devices.
