Description

Technical Field

[0001] This utility model relates to the field of mine safety warning technology, specifically a safety warning device for mine safety. Background Technology

[0002] Safety is paramount in mining operations. Due to the high-risk nature of mining, numerous potential hazards exist, such as collapses, roof falls, gas explosions, and equipment malfunctions. These hazards, once they occur, often result in severe casualties and property damage. Therefore, timely and effective safety warnings play a crucial role in preventing accidents and protecting the lives of workers.

[0003] According to patent number CN 221702173 U, a safety warning device for mine safety uses a protective cover to protect the warning light. Pulling the U-shaped plate moves the fixed block outward, causing the sliding rod to slide within the circular hole, generating tension in the spring. When one end of the sliding rod disengages from the circular groove, pulling the protective cover upward allows it to be removed for easy replacement. However, this existing device requires manual operation, with one hand pulling the U-shaped plate and the other hand manipulating the protective cover. In practice, this may require assistance from another person, making the operation cumbersome. Furthermore, traditional mine safety warning devices have limited functionality, typically only providing simple visual warnings. However, the mining environment is noisy, with various equipment generating significant noise. Relying solely on light warnings may cause workers to miss the warning signals due to focus on their work or being in blind spots, thus hindering timely response and increasing the risk of accidents. Therefore, we propose a safety warning device for mine safety. Utility Model Content
