The application discloses an elevator brake failure protection method, an elevator brake failure protection device, an elevator brake failure protection equipment and a storage medium. The method comprises the following steps: detecting the working state of the brake of the elevator; when the working state is failure, controlling the elevator to run to a leveling position; controlling an early door panel bypass door lock switch, the early door panel feeds back a door closing signal based on the bypass state of the door lock switch; when the door closing signal is a valid door closing signal, controlling the elevator to maintain the leveling and perform a door opening operation. The application aims to realize brake failure protection and improve the elevator riding experience of passengers.

This application relates to automatic fire alarm and linkage systems, specifically in the field of fire alarm technology. It includes an alarm body, a tiered voice warning system, a smoke sensor, a miniature camera, a sensing mechanism, and a connection structure. By incorporating a smoke sensor and a miniature camera, this application improves the accuracy of fire detection and reduces false alarms and missed alarms. The smoke sensor detects the ambient smoke concentration, while the miniature camera simultaneously captures environmental images and identifies smoke morphology. The two are electrically connected and work together to determine the fire's characteristics. Subsequent actions are triggered only when both detection results match preset fire smoke characteristics. This overcomes the limitations of traditional single-sensor detection, effectively distinguishing fire smoke from non-fire factors such as cooking fumes and construction dust, reducing the probability of false alarms and missed alarms, and preventing disruption to daily life due to false alarms or delays in fire response due to missed alarms. By incorporating a sensing mechanism, a pressure sensor, and a tiered voice warning system, it achieves tiered early warning, adapting to the initial stages of a fire.

The embodiment of the utility model relates to a braking mechanism, a rotating device and a transportation carrier, the braking mechanism is applied to the transportation carrier, the transportation carrier comprises the rotating device, the rotating device comprises a brake disc, the braking mechanism comprises a caliper support, a caliper body and a buffer assembly, and the caliper support is fixedly connected to the transportation carrier; the caliper body is movably connected to the caliper support, and the caliper support is used for clamping a brake disc. The buffering assembly is connected between the caliper body and the caliper support and used for buffering vibration between the caliper body and the caliper support. Under the arrangement of the embodiment of the invention, the brake mechanism can overcome larger vibration, so that the brake mechanism can effectively limit the rotation of the brake disc.

The application discloses a battery pack, comprising: an inner box body, a plurality of single batteries are arranged in the inner box body, and an exhaust port is arranged on the inner box body; an outer box body is arranged on the outer side of the inner box body, a discharge valve is arranged on the side wall of the outer box body, the exhaust port and the discharge valve form a discharge path from the single battery to the outer side of the battery pack, and a filtering assembly capable of filtering particles is arranged on the discharge path. In the battery pack, the discharge path for the single battery to flow out is arranged, and the filtering assembly is arranged on the discharge path. After the pressure of the single battery in the inner box body is out of control, the spraying material of the single battery can pass through the filtering assembly, the high-visibility particles are blocked by the filtering assembly, and the high-temperature gas passes through the filtering assembly and is discharged, so that the pressure relief of the single battery is realized, and the concentration of the visible material outside the battery pack is reduced, and the sensory effect is reduced.
