Description

[0001] The present invention relates to the technical field of gas detection, in particular to an intelligent portable gas detection and fall protection device.

[0002] The gas detection device, as a sensor unit of the portable safety protection system, forms the technical basis for preventive hazard prevention. Through continuous real-time monitoring of concentration fluctuations of specific gases (such as flammable or toxic gases), it initiates protective measures, transforming invisible gas hazards into quantifiable warning signals. It activates acousto-optical alarms, vibration warnings, and data transmission before dangerous limits are reached, creating an active protection mechanism based on the "monitor-warn-intervene" principle. This closed-loop control system fundamentally prevents serious accidents such as gas poisoning or explosions before they endanger people.

[0003] Chinese patent CN216293155U discloses a helmet with an integrated gas detection function. The invention combines the conventional protective function of a helmet with an intelligent gas monitoring unit, allowing the helmet to serve as both personal protective equipment and a gas warning device. The built-in acoustic-optical alarm automatically warns the wearer of gas leaks, enabling immediate hazard detection. This multifunctional solution combines protective function, automatic gas detection, and intelligent alarming in a single system, representing a significant improvement over conventional safety helmets. The automatic detection and warning function also increases the intelligence of the gas detection system and significantly improves occupational safety.

[0004] However, the implementation of the described technical solution revealed the following technical problems: Current gas detection devices use snap-lock connections for helmet mounting. These snap-lock connections tend to come loose due to significant wearer movement (e.g., due to work requirements) or accidental impacts. Furthermore, in noisy work environments, the reliability of information transmission is compromised, and data processing and integration have functional limitations. Technical problems to be solved

[0005] To address the shortcomings of the existing technology, this invention provides an intelligent wearable gas detection and fall protection device that solves the technical problem that in conventional gas detection devices with a snap-lock connection to the helmet, this connection structure is easily loosened during strong working movements or accidental impacts against the devices. Technical solutions

[0006] To solve the above problem, the invention offers the following technical solutions: An intelligent wearable gas detection and fall protection device comprising a wearable helmet provided with a fall protection mechanism for protection, the wearable helmet being provided with an additional handling mechanism, the fall protection mechanism comprising a rotary shaft, a mounting bracket, and a gas detector, the handling mechanism comprising a bow bracket and flexible earmuffs, a protective cavity being fixedly provided at a lateral end of the wearable helmet, the mounting bracket being slidably attached to the protective cavity, and the gas detector being arranged on an inner side wall of the mounting bracket, the flexible earmuffs being fixedly attached to the lower part of the wearable helmet, and a column slot being provided at the upper end of the protective cavity, a cushioning pad being fixedly attached to the inner side wall of the column slot.wherein the rotary shaft is rotatably mounted on the inner side wall of the damping pad, a cross-limit lock is fixedly mounted on the peripheral end of the rotary shaft, two L-shaped brackets are fixedly mounted on the upper end of the mounting bracket, two springs and telescopic rods are fixedly mounted between the two L-shaped brackets and the protective cavity, the telescopic rod is arranged on the inner side wall of the spring, and a dust protection net is fixedly mounted on the lateral end of the protective cavity.

[0007] Preferably, a speaker is permanently attached to the inner side wall of the flexible earmuff.

[0008] Preferably, the bow bracket is fixedly attached to the lower end of the wearable helmet, with a processor fixedly attached to the inner side wall of the bow bracket. Beneficial effects:

[0009] This device replaces the fragile snap-lock connections with a one-piece injection-molded protective cavity construction that is seamlessly connected to the wearable helmet, significantly increasing connection stability and safety. This reliably prevents the device from detaching in the event of sudden movements or accidental impacts by the wearer. The integrated dust protection net on the front effectively blocks dust particles, improving the protective effect, ensuring the high-precision operation of the gas detector and extending its service life.

[0010] The device is seamlessly connected to the wearable helmet through a one-piece injection-molded protective cavity, replacing the easily detachable snap-on structure and increasing the stability and safety of the connection. This prevents the device from falling off due to strenuous personnel movements or accidental impact. The integrated dust protection net at the front end effectively blocks dust and improves protection performance, ensuring high-precision operation and extending the service life of the gas detector.
