Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing in stereo garages, in particular to a special automatic fire extinguishing system for vertical circulation stereo garages. Background Art

[0002] The vertical circulation stereo garage is easy to operate and has a high degree of automation control. As a stereo parking equipment with a large number of parking spaces, the smallest footprint, and the simplest and most reliable operation, it can better solve the increasingly prominent parking problem. For a long time, it has been relatively difficult to arrange a fire protection system in a stereo garage because the vehicle transfer vehicle or parking space of the stereo garage is constantly moving; and the vertical circulation stereo garage has a vehicle transfer vehicle and a parking space combined into one, and all its parking spaces rotate in a forward / reverse cycle in the vertical direction, so its fire protection system is more difficult to set up and apply than other stereo garages.

[0003] The existing vertical circulation stereo garages are equipped with fire-fighting facilities, most of which adopt complete sets of technologies, generally consisting of fire sprinklers, sensors, fire extinguishing agent pipelines, control lines, fire extinguishing agent storage tanks, centralized control systems, etc. arranged on each parking space. When a fire occurs in a vehicle in a parking space on a certain floor, the sensor on the parking space reaches the threshold, triggering an alarm, and the fire extinguishing agent is sprayed from the sprinkler to extinguish the fire by manual operation or automatic system control. Since the parking spaces of the vertical circulation stereo garage rotate in a forward / reverse cycle in the vertical direction, the fire extinguishing agent pipelines and control lines of its fire-fighting system are easily entangled and pulled apart and cannot be used. In addition, the fire can easily deform or fuse the pipelines and lines, causing the fire-fighting operation to fail. Therefore, there are very few vertical circulation stereo garages equipped with fire-fighting facilities on the market, and many technologies remain at the patent technology level and cannot be effectively implemented.

[0004] The patent with the publication number CN 218165864 U discloses an independent fire extinguishing device for a vertical circulation stereo garage, wherein an independent fire extinguishing device is provided on the long axis at the top of each vehicle loading platform of the vertical circulation stereo garage, and the independent fire extinguishing device is directly below the fire prone area where the parked vehicles are located. The outstanding defect is that after the fire occurs, the alarm cannot be quickly sounded. The independent fire extinguishing device is suspended, and the spraying angle is not fixed; the overheating of the line in the front part of the vehicle is the cause of the fire. When a fire occurs, it is not considered to extinguish the fire from the fire source at the first time, and the fire extinguishing effect is not good. The independent fire extinguishing device is directly below the fire prone area where the parked vehicles are located, and the independent fire extinguishing device is installed by hanging on the long axis at the top of the vehicle loading platform. The height of the vehicle parked on the vehicle loading platform is not fixed, and it is not safe for the vehicle to enter and exit the vehicle loading platform. Due to the limited installation space, the independent fire extinguishing device used is small in size and can be loaded with less fire extinguishing agent. The independent fire extinguishing device is installed by long-axis suspension on the top of the vehicle platform. The independent fire extinguishing device is distributed above the center axis of the vehicle, which is relatively scattered and cannot form a fire extinguishing force. Especially for the fire extinguishing device above the rear of the vehicle, the fire has a great momentum when it burns to this part, and the fire extinguishing is ineffective. The independent fire extinguishing device is installed by suspension. When the independent fire extinguishing device is used to extinguish a fire, the direction is not fixed and the fire extinguishing effect is uncertain. Summary of the invention
