Fire-fighting spraying device for smart city large-scale supermarket center

Abstract

The invention discloses a fire-fighting spraying device for a smart city large-scale supermarket center, and particularly relates to the field of smart cities. The fire-fighting spraying device comprises a connecting end, a control valve cavity is fixedly installed at the bottom end of the connecting end, a piston valve cavity is fixedly connected to one side of the control valve cavity, and a fire temperature sensing mechanism is fixedly installed at the bottom end of the piston valve cavity; a locking mechanism is arranged in the piston valve cavity, a splash box connecting base is fixedly installed at the bottom end of the control valve cavity, a rotary splash mechanism is fixedly installed at the inner side of the splash box connecting base, and the connecting end comprises a threadedconnecting end and a fastening nut; and by arranging a mechanical control assembly structure, a temperature sensing piston rod type fire disaster temperature sensing mechanism is used for sensing theenvironment temperature and automatically controlling locking and opening of the valve body, automatic spraying starting is achieved, a non-electronic control structure enables the device to be more stable in use, not prone to being interfered by the external environment and low in limited condition, frequent maintenance is not needed and maintenance cost is saved.

Description

technical field [0001] The invention relates to the technical field of smart cities, and more specifically, the invention is a fire sprinkler device for a large supermarket center in a smart city. Background technique [0002] With the development of smart cities and the improvement of economic and consumption levels, large shopping malls and commercial centers have sprung up one after another, with a large population flow and more flammable items. The safety of the shopping environment is also closely related to brand management. Therefore, strengthening fire safety management and maintaining the health of fire protection facilities such as evacuation channels and indication systems, smoke prevention, and fire separation are the key concerns of large supermarkets and commercial centers. [0003] Almost any form of combustion process will produce smoke gas with certain toxicity. The toxicity comes not only from carbon monoxide gas, but also from various plastic components in...

Problems solved by technology

[0004] And present fire-fighting sprinkler device mainly adopts glass tube, fusible alloy or electric induction control as the trigger mechanism of fire-fighting sprinkler device, and it all has certain defect, as: when the temperature of glass tube burst trigger type sprinkler device exceeds subzero Below 5°C, it will freeze and crack, and the water will freeze. The water in the pipeline will burst the glass tube and cause "self-explosion"; It is not sensitive for rapid triggering; while electric induction control is mainly through temperature sensors or smoke alarms, which are sensitive, but it requires an external independent power supply and the connection of the power supply path, and there are many restrictions. In the face of complex fire emergencies The situation is prone to abnormalities and the stability is poor; in addition, most of the mechanical traditional fire sprinkler devices are mostly disposable structures, which cannot be reused. After the alarm is accidentally triggered or the device fails, it cannot be used again, and the cost is relatively high. Large, with certain limitations
