Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to a special intelligent fire alarm and monitoring system for prefabricated cabins. Background Technology

[0002] With the ongoing advancement of smart grid construction, prefabricated synchronous condenser cabins, as core facilities ensuring the stable operation of power systems, are finding increasingly widespread application. These cabins, constructed using modular factory production and on-site assembly, are steel structures that rigorously protect the synchronous condenser, a critical device used to adjust the phase angle of the power system and maintain system synchronization. The cabin not only houses the synchronous condenser itself but also houses various high-voltage electrical equipment, complex cable lines, and automatic phase sequence detection and compensation devices. During long-term operation, these devices are susceptible to fires due to voltage fluctuations, load changes, and abnormal temperatures, particularly caused by electrical faults, aging wiring, and poor heat dissipation. Because the prefabricated cabin is relatively enclosed, once a fire spreads, it can lead not only to phase imbalance and power outages but also irreversible damage to equipment, seriously threatening the lives of maintenance personnel.

[0003] Current general-purpose fire alarm systems on the market are insufficient to meet the unique requirements of prefabricated synchronous condenser compartments. On one hand, the complex electromagnetic environment within these compartments makes signal transmission from traditional fire detectors susceptible to interference, frequently resulting in false alarms and missed alarms, hindering timely and accurate fire monitoring. On the other hand, existing alarm systems lack linkage mechanisms with in-compartment communication and evacuation equipment. After a fire breaks out, they cannot quickly provide voice warnings, emergency communication, and evacuation guidance via wall-mounted speakers, wall-mounted telephones, and fire horns, missing the optimal window for initial fire response. Furthermore, the compact layout and unique spatial structure of prefabricated synchronous condenser compartments make it difficult for traditional alarm systems to achieve comprehensive, blind-spot-free fire coverage monitoring, failing to meet their stringent fire prevention requirements. Therefore, developing a dedicated intelligent fire alarm monitoring system adapted to the complex environment and functional needs of prefabricated synchronous condenser compartments, enabling accurate early fire detection, rapid response, and efficient linkage control, has become an urgent need to ensure the safe and stable operation of power systems. Utility Model Content

[0004] The purpose of this utility model is to address this issue by proposing a dedicated intelligent fire alarm and monitoring system for prefabricated cabins. This system can convert smoke, heat, and flames generated by combustion into electrical signals and transmit them to the fire alarm controller. It can then notify the personnel inside the cabin in the form of sound and light, while simultaneously recording the location and time of the fire. This facilitates timely detection of fires and extinguishing of initial fires, minimizing loss of life and property.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a prefabricated cabin-specific intelligent fire alarm monitoring system, comprising a connected triggering device, a fire alarm system, and a linkage output device. The triggering device includes an infrared beam detector, a manual alarm button, and an audible and visual alarm installed inside the prefabricated cabin. The linkage output device includes a wall-mounted speaker, a wall-mounted telephone, and a fire horn installed inside the prefabricated cabin. The fire alarm system includes a fire alarm host with a built-in backup battery, a telephone switchboard, and a broadcast host. The infrared beam detector, manual alarm button, and audible and visual alarm are electrically connected to the fire alarm host, the wall-mounted telephone is connected to the telephone switchboard, and the wall-mounted speaker is connected to the broadcast host.

[0006] To further optimize this utility model, the following technical solutions may be preferred:

[0007] Preferably, the infrared beam detector includes a transmitter and a receiver movably disposed within the prefabricated cabin. A movable seat is disposed within the prefabricated cabin corresponding to the positions of the transmitter and receiver. A slide rail is disposed within the prefabricated cabin along its length. The movable seat is slidably disposed on the slide rail and is connected to a reciprocating drive mechanism.

[0008] Preferably, the prefabricated cabin is also equipped with a negative pressure ventilation system, which includes a ventilation port installed on the outer wall of the prefabricated cabin and connected to a negative pressure fan.

[0009] Preferably, it also includes an auxiliary control device, which includes a dynamic environment detection module. The dynamic environment detection module includes an environment detection input mechanism, which includes a temperature and humidity sensor and a water immersion detector installed in the prefabricated cabin. The signals from the temperature and humidity sensor and the water immersion detector are transmitted to the control backend through a four-core shielded signal cable. The control backend includes a connected LCD display, a hard disk burner, a network switch, and a dynamic environment host.

[0010] Preferably, the auxiliary control device includes an access control module and a camera module. The access control module includes a security access control system equipped with an electric lock. The security access control system is equipped with an exit button and a card reader. The electric lock, exit button, and card reader are connected to the access control host via a 10-core access control cable. The access control host is connected to a network switch.

[0011] Preferably, the auxiliary control device includes multiple indoor dome cameras installed in the prefabricated cabin, and the indoor dome cameras are connected to a network switch via Cat5e network cables.

[0012] This prefabricated cabin-specific intelligent fire alarm and monitoring system has many significant benefits.

[0013] Firstly, the transmitter and receiver of the infrared beam detector are connected by a movable base and a sliding rail, and can move flexibly under the action of a reciprocating drive mechanism, which can cover different areas of the prefabricated cabin, avoid blind spots, and improve the comprehensiveness and accuracy of fire detection.

[0014] Secondly, the negative pressure ventilation system, through the setting of negative pressure fans and exhaust vents, can quickly extract the smoke generated by combustion in the prefabricated cabin, making the smoke easier for detectors to capture, while reducing the smoke concentration in the cabin, thus buying time for personnel evacuation and rescue.

[0015] Third, the dynamic environment detection module in the auxiliary control device uses temperature and humidity sensors and water immersion detectors to monitor the cabin environment in real time, provide early warning of potential hazards such as abnormal temperature and humidity and water leakage, and realize data storage, display and remote transmission in combination with the control backend, so that operation and maintenance personnel can keep track of the cabin conditions.

[0016] Fourth, the access control module, in conjunction with electric locks, card readers, and other equipment, can effectively control personnel entry and exit, preventing unauthorized personnel from entering and causing security problems.

[0017] Fifth, the indoor dome camera transmits data through a network switch, enabling real-time monitoring of equipment operation and personnel activities within the cabin. It also works in conjunction with the fire alarm system to provide visual evidence for fire response, comprehensively enhancing the safety and protection level of the prefabricated cabin and minimizing losses caused by fire and other risks.
