Description

Technical Field

[0001] The utility model relates to the technical field of fire alarm controllers, in particular to a (nuclear power) cabinet-type fire alarm controller. Background Art

[0002] The fire alarm controller is a core component of the automatic fire alarm system and has the following functions: 1) It receives fire signals and activates the fire alarm system. It also indicates the location of the fire and records relevant information. 2) It can activate fire alarm signals through the fire alarm transmitter or activate automatic fire extinguishing equipment and fire linkage control equipment through the automatic fire extinguishing control system. 3) It automatically monitors the correct operation of the system and provides audible and visual alarms for specific faults.

[0003] Fire alarm controllers come in a variety of configurations to suit different installation requirements and usage scenarios. Cabinet-style fire alarm controllers are typically larger, vertical cabinets with a more robust structure. They can accommodate more hardware components, such as multiple inputs, outputs, and communication interfaces, making them suitable for fire alarm systems in larger buildings and industrial facilities.

[0004] Existing cabinet-type fire alarm controllers have the following technical problems in nuclear power plants and similar high-demand environments:

[0005] Insufficient seismic resistance: Existing products have limited seismic resistance when facing external shocks such as earthquakes, which may cause the risk of equipment damage.

[0006] Low IP protection level: Most products have a low IP protection level and cannot effectively protect against adverse factors such as humidity, dust, and impact in special environments such as nuclear power plants, making the equipment vulnerable to damage.

[0007] In an environment like a nuclear power plant, where equipment stability and reliability are extremely demanding, these issues become critical factors for safe operation. Over long-term use, uncontrollable factors such as earthquakes, unexpected shocks, high humidity, and dust can affect performance, posing safety risks. Utility Model Content

The pair of side cover bodies are arranged on opposite sides of the incoming wire cover body and are fixedly connected to the incoming wire cover body or formed as one piece. The protective cover is fixedly connected to the bottom of the mounting frame so that the incoming wire cover body is covered on the incoming wire port at the bottom of the mounting frame, and the pair of side cover bodies are correspondingly covered on the fixed mounting plates on both sides of the bottom of the mounting frame.

[0016] As one embodiment of the present invention, an observation window is provided in the middle of each cabinet door and is matched with a window glass. The cabinet door and the window glass are sealed by a first sealing structure. When the cabinet door is closed, the cabinet door and the cabinet body are sealed by a second sealing structure.

[0017] As one of the embodiments of the present invention, the cabinet frame cover is arranged outside the mounting frame and is fixedly connected to the mounting frame. The doorway edge of each mounting side frame of the mounting frame is turned outward and extends beyond the doorway edge of the corresponding cabinet frame to form a door frame. A sealing ring is installed on each cabinet door. When each cabinet door is closed, the door frame is pressed against the corresponding sealing ring to form a second sealing structure.

[0018] As one embodiment of the present invention, the first sealing structure includes a glass fixing frame and a U-shaped sealing ring, the U-shaped sealing ring wraps the outer edge of the window glass and is tightly attached to the cabinet door through the glass fixing frame.

[0019] As one embodiment of the present invention, the glass fixing frame includes a first Z-shaped plate and a second Z-shaped plate. The first Z-shaped plate is fixed on the cabinet door near the observation window, so that one end of the Z shape of the first Z-shaped plate extends toward the observation window, and one end of the Z shape of the second Z-shaped plate is fixed on the extended end of the first Z-shaped plate, so that the other end of the Z shape of the second Z-shaped plate presses the U-shaped sealing ring on the cabinet door.
