This invention relates to the field of audible warning technology, and more specifically, to a safety warning device for trackless rubber-tired vehicles. The device includes a housing fixedly installed on the trackless rubber-tired vehicle, and a pneumatic mechanism is disposed within the housing. The pneumatic mechanism consists of a cylinder, a first piston, and a telescopic rod. The first piston is movably disposed inside the cylinder, and its top end is fixedly connected to one end of the telescopic rod. The telescopic rod passes through the top end of the cylinder and extends to its exterior. The circumferential sidewall of the telescopic rod has linearly arranged toothed grooves along the axial direction, and one side of the telescopic rod has transmission teeth that mesh with the toothed grooves. A speed ratio mechanism and a delay mechanism are respectively disposed on both sides of the transmission teeth, and the transmission teeth, speed ratio mechanism, and delay mechanism are coaxially arranged. The transmission end of the speed ratio mechanism is connected to a pneumatic warning mechanism. This invention solves the problem that warning devices for trackless rubber-tired vehicles rely on electric power or require manual operation when temporarily stopped in mines.

A portable multi-purpose detector, characterized in that it comprises a housing (1) wherein the housing (1) is provided with a handle (11), a control board (2) is arranged in the housing (1), and an infrared detector (3) and a red light generator (4) are arranged on the housing (1); wherein the infrared detector (3) and the red light generator (4) are both electrically connected to the control board (2); the infrared detector (3) serves to detect red light emitted by a camera; the red light generator (4) serves to emit red light in the direction of the camera; wherein the control board (2) is further provided with a signal detection module (5) which serves to detect whether a communication signal is present in the environment.

The present disclosure provides a filter monitoring apparatus (herein also referred to as an alarm device) for alerting a user to clean filters (including split air conditioner filters and window air conditioner filters). The filter monitoring apparatus comprises an anterior module and a posterior module configured to be positioned on opposite sides of a filter, wherein the anterior module includes anterior magnets and the posterior module includes posterior magnets, the anterior magnets and posterior magnets configured to magnetically couple the anterior module and posterior module together with the filter positioned therebetween. A laser emitter disposed in the anterior module is configured to emit a laser beam through the filter toward the posterior module. A photodetector disposed in the posterior module is positioned to receive the laser beam from the laser emitter when the filter is clean. An alarm circuit comprises an acoustic alarm device and an alert indicator. An electronic circuit operatively connected to the photodetector and the alarm circuit is configured to activate the alarm circuit when the photodetector does not receive the laser beam due to dust accumulation on the filter blocking the laser beam.

The application discloses a fishing reel brake alarm device with reinforced brake force, which comprises a main shaft, a stop gear, a main gear, a brake assembly and a sound generating assembly which are sleeved on the main shaft. An installation cavity is formed on the end face of the main gear to accommodate the brake assembly and the sound generating assembly. The sound generating assembly comprises a gear ring which is coaxial with the installation cavity and is provided with a driving gear on the inner wall of the bottom of the gear ring. A center hole is formed in the center of the pressing disc and is connected to the main shaft in the axial direction. An elastic separation structure is arranged on the end face of the pressing disc which faces the bottom of the gear ring. The elastic separation structure arranged on the pressing disc can make the pressing force between the brake assembly more uniform. The elastic separation structure can further enhance the pressing force of the brake assembly, thereby enhancing the brake force of the brake assembly and the take-up capacity of the reel.
