（一）大空间智能灭火装置

（1） Large space intelligent fire extinguishing device

大空间智能灭火装置（简称智能灭火装置）的灭火喷水面为一个圆形面，由智能型红外探测组件、大空间大流量喷头、电磁阀组三部分组成，其中红外探测组件与喷头及电磁阀均为独立设置。该装置能主动探测着火部位并开启喷头喷水灭火，其保护半径大、灭火针对性强，适用于对保护区域进行大面积覆盖的场合。

The fire extinguishing spray surface of the large space intelligent fire extinguishing device (referred to as the intelligent fire extinguishing device) is a circular surface, consisting of three parts: an intelligent infrared detection component, a large space high flow nozzle, and an electromagnetic valve group. The infrared detection component, nozzle, and electromagnetic valve are all independently set. This device can actively detect the location of the fire and activate the nozzle to spray water for fire extinguishing. It has a large protection radius and strong fire extinguishing specificity, making it suitable for situations where the protected area is covered over a large area.

（二）自动扫描射水灭火装置

（2） Automatic scanning water jet fire extinguishing device

自动扫描射水灭火装置（简称射水灭火装置）的灭火射水面为一个扇形面，由智能型红外探测组件、扫描射水喷头、机械传动装置、电磁阀组四大部分组成。与智能灭火装置不同的是，其红外探测组件、扫描射水喷头和机械传动装置为相结合设置。该装置通过机械传动实现喷头的扫描动作，扩大了单台装置的有效保护范围。

The fire extinguishing water surface of the automatic scanning water jet fire extinguishing device (referred to as the water jet fire extinguishing device) is a fan-shaped surface, consisting of four main parts: intelligent infrared detection components, scanning water jet nozzles, mechanical transmission devices, and solenoid valve groups. Unlike intelligent fire extinguishing devices, its infrared detection components, scanning water jet nozzles, and mechanical transmission devices are integrated. This device achieves the scanning action of the nozzle through mechanical transmission, expanding the effective protection range of a single device.

（三）自动扫描射水高空水炮灭火装置

（3） Automatic scanning high-altitude water cannon fire extinguishing device

自动扫描射水高空水炮灭火装置的灭火射水面为一个矩形面，由智能型探测组件、自动扫描射水高空水炮、机械传动装置、电磁阀组四大部分组成，前三者采用相结合设置。该装置安装高度为6米至20米，标准保护半径不超过20米，喷水流量不低于5L/s。其灭火射水面为矩形，能更有针对性地覆盖特定形状的保护区域。

The fire extinguishing water surface of the automatic scanning high-altitude water cannon fire extinguishing device is a rectangular surface, consisting of four parts: intelligent detection components, automatic scanning high-altitude water cannon, mechanical transmission device, and solenoid valve group. The first three parts are integrated. The installation height of the device ranges from 6 meters to 20 meters, with a standard protection radius of no more than 20 meters and a water spray flow rate of no less than 5L/s. Its fire extinguishing water surface is rectangular, which can cover specific shaped protection areas more targetedly.
