Description

Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, and particularly to an intelligent fire-fighting alarm system. Background Art

[0002] The fire alarm system is a comprehensive device, which consists of a trigger device, a fire alarm device, a linkage output device and other auxiliary function devices. Its main function is to detect physical quantities such as smoke, heat, and flames generated by combustion at the early stage of a fire, and convert this information into electrical signals through fire detectors and transmit them to the fire alarm controller. At the same time, the system notifies the entire floor to evacuate through sound or light, and the controller records information such as the location and time of the fire. The manual intelligent fire alarm is a type of equipment in the fire alarm system. When someone discovers a fire and the fire detector does not detect the fire, the person manually presses the manual fire alarm button, and the manual intelligent fire alarm can send the fire signal to the fire control central control system to complete the alarm.

[0003] Manual intelligent fire alarms are usually installed on walls of walkways, stairways, etc., and are mostly exposed to the outside and relatively conspicuous so that people can easily notice them. However, manual intelligent fire alarms exposed to the outside are easily hit by external forces, which may cause the manual intelligent fire alarms to be accidentally triggered, sound an alarm, and start the operation of the fire control central control system, thus causing a certain waste of firefighting resources. Therefore, how to better avoid the intelligent fire alarms from being accidentally triggered is an important issue that needs to be solved in the design of intelligent fire alarm systems. Utility Model Content

[0004] The utility model provides an intelligent fire alarm system in order to solve the problem of preventing the intelligent fire alarm from being triggered by mistake.

[0024] Preferably, the clamping frame and the clamping slot cooperate with each other.

[0025] In the technical solution, the card-jointed frame is snapped into the card-jointed groove, so as to fix and restrict the movable frame.

[0026] On the basis of conforming to the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0027] The positive and progressive effects of the utility model are:

[0028] 1. By extending the hand into the gap between the pulling frame and the moving frame and pulling outward, the hand first pulls the pulling frame to move, the pulling frame drives the insertion block to move, the insertion block is inserted between the card-connecting frames, and drives the card-connecting frame to move upward, so that the card-connecting frame is disengaged from the card-connecting slot, and the moving frame is no longer restricted. It continues to be pulled outward, and the handle frame drives the moving frame to move outward as it is pulled. The moving frame presses the push switch, and the main body of the intelligent fire alarm sounds an alarm, which is convenient and quick to start the intelligent fire alarm and sound an alarm.

[0029] 2. The mobile frame is fixed and restricted by snapping the snap-in frame into the snap-in slot, so as to prevent the mobile frame from moving when it is hit, causing the intelligent fire alarm to be accidentally triggered and alarmed.
