Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire protection, in particular to a fire protection-linked cold channel control system. Background Art
[0002] Fire linkage control means that after the fire detector detects a fire signal, it can automatically cut off the relevant air conditioners in the alarm area, close the fire dampers on the pipes, stop the relevant fan, open the smoke exhaust valves on the relevant pipes, automatically close the electric fire doors and fire shutter doors in the relevant parts, cut off the non-fire power supply in sequence, turn on the emergency lighting and evacuation sign lights, stop all elevators except the fire elevators, and immediately start the fire extinguishing system through the controller in the control center for automatic fire extinguishing.
[0003] In the prior art, a Chinese patent with publication number CN215291913U proposes a fire-linked cold channel control system, which links the environmental sensor in the cold channel with the skylight for control. When a fire alarm occurs, the connection is disconnected and the skylight automatically flips over. While dissipating heat quickly, fire-fighting gas can enter the computer room through the skylight over a large area to protect the equipment in the computer room. However, in actual application, the skylight is controlled by an electronic control component. When a fire occurs, the control component of the skylight is damaged, making it impossible for the skylight to flip over normally, affecting the fire-fighting gas from entering the computer room to protect the equipment in the computer room. Therefore, we disclose a fire-linked cold channel control system. Utility Model Content

[0014] Preferably, a connecting plate is fixedly connected to the side of the skylight, and two adjacent connecting plates are respectively located at the upper and lower ends of the skylight connected thereto.
[0015] The beneficial effects of the utility model are as follows: the top plate of the machine room limits the moving position of the skylight through the first rotating shaft, so that the first rotating shaft drives the skylight to rotate through the rotation of the other end, so that when a fire occurs in the machine room, multiple skylights can rotate normally, ensuring that the fire-fighting gas can smoothly pass through the skylight to enter the machine room for fire extinguishing. After the motor receives the corresponding electric control element signal, it will drive the skylight to flip ninety degrees through the transmission gear and the first rotating shaft, so that the skylight is opened to the most suitable angle for the fire-fighting gas to enter, which is conducive to the fire-fighting gas entering the machine room, and the transmission gear will drive the rack to move when rotating, so that all the transmission gears will rotate, preventing the electric control components connected to a certain motor from being damaged, resulting in the motor not receiving the electric signal, so that the corresponding skylight cannot be opened, ensuring that all the skylights can be opened normally, avoiding the problem of affecting the fire-fighting gas to enter the machine room to protect the equipment in the machine room;
[0016] The rotation groove is C-shaped, and the limit plate is located in the rotation groove. The angles of two adjacent rotation grooves differ by ninety degrees, and the two limit grooves differ by ninety degrees, so that the rotation groove limits the rotation of the sunroof by ninety degrees through the limit plate, ensuring that the sunroof rotates to the required angle without affecting the rotation of the connecting plate and the sunroof.
