Description

Technical Field

[0001] The utility model relates to the technical field of fire monitoring, in particular to an electrical fire monitoring and alarm device. Background Art

[0002] The gas fire monitoring system is characterized by its early warning system for leakage monitoring. Unlike the traditional automatic fire alarm system, the early alarm of the electrical fire monitoring system is to avoid losses, while the traditional automatic fire alarm system is to reduce losses. At present, in order to quickly and effectively collect smoke, wind suction alarm devices have appeared on the market. The structure of this alarm device mainly includes a smoking pipe, an alarm and a fan. The fan and the alarm are located in the smoking pipe. When the fan is started, it can accelerate the air around the smoking pipe into the smoking pipe, and then trigger the alarm.

[0003] For example, a Chinese patent with announcement number CN217740001U discloses an electrical fire monitoring alarm device, including a smoking pipe and an alarm. The outside of the smoking pipe is detachably connected to a smoke collecting pipe, and the outer peripheral wall of the smoke collecting pipe is provided with axially distributed smoke inlet holes. The utility model arranges the smoke collecting pipe on the outside of the smoking pipe, and the smoking pipe is connected to the inner cavity of the smoke collecting pipe through a guide pipe. A fan and a smoke collection head are arranged in the smoking pipe, and the alarm is arranged and installed on the outside of the smoking pipe. The outer wall of the smoke collecting pipe is provided with axially distributed smoke inlet holes. The smoke collecting pipe increases the range of smoke collection in the smoking pipe. When the fan is started, the smoke away from the smoking pipe quickly enters the smoking pipe, so that a timely alarm can be issued at the early stage of a fire.

[0004] Although the above example can expand the monitoring range of the electrical fire monitoring alarm device by lengthening the smoke pipe, the amount of smoke let in by the longer smoke pipe is limited by the output air volume of the fan. When the smoke inlet close to the fan can meet the output air volume of the fan, the smoke inlet far away from the fan will gradually slow down the smoke intake speed according to the distance from the fan until the smoke intake stops. As a result, when an electrical fire occurs in an area far away from the fan, an alarm cannot be sounded in time, which causes certain inconveniences in use. Utility Model Content

[0011] A further improvement of the technical solution of the utility model is that the electrical fire monitoring alarm mechanism comprises a fixing plate, the top of the fixing plate is bolted to the bottom of the mounting member, and the bottom of the fixing plate is fixedly connected with a mounting box.

[0012] A further improvement of the technical solution of the utility model is that: a spring is fixedly connected to the top of the inner cavity of the installation box, a pressure plate is fixedly connected to the bottom of the spring, and a smoke alarm is overlapped on the bottom of the pressure plate.

During the sliding process, air is sucked into the electrical fire monitoring and alarm mechanism for monitoring, thereby increasing the monitoring area. At the same time, the situation in which the smoke inlet far away from the fan position cannot take in smoke due to the excessive length of the air inlet pipe can be avoided, making it more convenient to use. At the same time, the arrangement of the camera mechanism can perform video monitoring of the monitoring area during the sliding process. When a fire occurs, the size of the electrical fire can be observed through the camera to facilitate the formulation of rescue measures. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In this embodiment, the movable wheel 26 is driven to rotate by the rotation shaft of the motor 24, so that the movable wheel 26 rolls along the top of the sliding rail 11, thereby driving the electrical fire monitoring alarm mechanism 3 to slide along the sliding rail 11.
