However, it has also brought the dangers of electrical fires. Electrical fires generally refer to fires caused by the release of heat energy due to faults in electrical circuits, electrical equipment, appliances, and power supply and distribution equipment, such as high temperatures, electric arcs, and electric sparks, as well as non-fault-related energy releases, such as the hot surface of electric heating appliances. These fires ignite the appliance itself or other combustibles under conditions suitable for combustion. They also include fires caused by lightning and static electricity.

The monitoring component includes a turntable, a hinge seat fixedly mounted on one end of the top of the turntable, and an infrared camera rotatably mounted on the inner side of the hinge seat via a pin. One end of the infrared camera is hinged to an electric telescopic rod. A drive mechanism is installed inside the mounting box, including a motor, a half gear, an internal gear seat, a rack, and a transmission gear. This invention realizes the automatic patrol function of the infrared camera, and the electric telescopic rod can adjust the angle of the infrared camera, thereby expanding the patrol range of the infrared camera.

[0005] Traditional devices rely on single-parameter threshold alarms such as smoke or temperature, which cannot identify complex fire hazards such as overheating of electrical circuits, arc faults, and flammable gas leaks in the early stages.

[0006] Traditional equipment is prone to malfunction due to insufficient heat dissipation of internal electronic components, and conventional fan cooling suffers from reduced efficiency under the high temperatures of a fire.

[0027] 1. This invention includes an alarm monitoring device.

It can display alarm types such as fire alarms and leakage alarms, alarm levels, fault locations, and temperature change trends, facilitating quick understanding of equipment status and appropriate action by on-site personnel and remote monitoring personnel. Relays perform control functions in the fire alarm system.

They are usually used in conjunction with a display screen to ensure that personnel can still hear the alarm and take appropriate protective measures even in noisy environments. The sensor data acquisition module is used to acquire data from different locations through multiple sets of sensors to make subsequent judgments and switch operating modes. The cooling control module is used to dynamically switch the heat dissipation mode based on data from the second internal temperature sensor. When the gas quality sensor detects combustible gas, it forcibly closes all air inlets and switches to internal circulation heat dissipation, which is achieved through exhaust ventilation using several bidirectional fan designs.

This invention, through multi-sensor collaboration, can identify various fire causes at an early stage, significantly advancing the warning time and ensuring continuous operation in the fire scene. Through multiple relay redundancy mechanisms, backup power outages are guaranteed, thereby improving the success rate of power outages. The worm gear angle adjustment design reduces monitoring blind spots during equipment operation.

When the gas quality sensor 22 detects combustible gas, it forcibly closes all air inlets and switches to internal circulation heat dissipation, that is, it uses several fans with bidirectional fan design structure for exhaust treatment.

[0056] Please see Figures 1-8 The working principle of this invention is as follows:

[0057] This invention includes an alarm monitoring device. The display screen 21 is used to display the real-time operating status, alarm information, temperature data, gas concentration, and other key information of the electrical fire monitoring system. It can display alarm types such as fire alarms and leakage alarms, alarm levels, fault locations, and temperature change trends, facilitating on-site personnel and remote monitoring personnel to quickly understand the equipment status and take appropriate measures. The gas quality sensor 22 is used to detect the concentration of potentially fire-related harmful gases such as carbon monoxide, carbon dioxide, and combustible gases. Once the gas concentration exceeds a set safety threshold, the system will trigger an alarm to remind personnel to take preventative measures. The relay 23 is used in the fire alarm system. The relay 23 performs control functions. Once the sensor detects an anomaly such as excessively high temperature, leakage, or excessively high gas concentration, it will trigger relevant control actions according to preset logic, such as cutting off the power supply or activating fire-fighting equipment. Multiple settings are provided to prevent the failure of timely power-off operation due to one fault, offering a backup option. The external temperature sensor 24 is used to monitor temperature changes in the external environment, especially the temperature around electrical equipment, lines, transformers, etc. It provides early warning by detecting abnormal temperatures in the early stages of a fire to prevent the fire from occurring. The buzzer 25 provides an audible alarm to alert personnel to any abnormalities in the electrical fire alarm system. It is usually used in conjunction with the display screen 21 to ensure immediate detection and alarm response. To ensure that personnel can still hear the alarm sound and take appropriate protective measures even in noisy environments, the first fan 16, the third fan 54, and the second fan 52 are all bidirectional fans. A second filter 58, used in conjunction with the third fan 54, is provided on the side of the heat dissipation box 3 near the on-site alarm terminal 1. This filter works in conjunction with the normal cooling airflow. Two second internal temperature sensors 57 are used to monitor and process the temperature changes inside the heat dissipation box 34 in real time, thereby controlling the operation of the corresponding fans. During normal operation, the third fan 54 blows air normally, which can be guided through the first heat dissipation slit 19 to the inside of the on-site alarm terminal 1 to accelerate heat dissipation. When the internal temperature of the on-site alarm terminal 1 reaches a preset value, semiconductor cooling is activated. Both plate 5 and the third fan 54 operate, promptly delivering cooling gas to the interior of the on-site alarm terminal 1 for auxiliary heat dissipation. This ensures that the overall temperature of the on-site alarm terminal 1 and control panel 2 is not affected by the external environment, allowing them to continue operating normally even in the event of a fire, thus providing a remote alarm function. The drive motor 48 rotates, driving the worm gear 46 and worm wheel 47 inside the fixed cover 45, which in turn drives the rotating disk 49 on one side of the fixed cover 45.
