Title
(EN) Intelligent sprinkler head
(ZH) 一种智能洒水喷头
Abstract
(EN)
The invention discloses an intelligent sprinkler head. The intelligent sprinkler head comprises a sprinkler head shell internally provided with a water inlet; the interior of the water inlet is fixedly connected with a sealing board; the bottom side of the sprinkler head shell is fixedly connected with a metal storage box; a heat conduction wire is wound on the outer side wall of the metal storagebox; the metal storage box is filled with low-boiling-point solutions; the interior of the metal storage box is in sliding connection with a piston block; the upper side of the piston block is fixedly connected with a piston rod; and the end, sequentially penetrating through the metal storage box and the sealing board, of the piston rod is fixedly connected with a slide plug. A reserved cooling cavity is full of water to be tightly attached to the outer wall of the metal storage box, the water flows out of a water outlet hole to bring away heat energy, the metal storage box is helped to be rapidly cooled, the low-boiling-point solutions under a gas state are liquidized again, and accordingly the piston block resets under the condition of elasticity of a spring, the piston rod is driven toreset, the slide plug plugs an inverted conical opening again, water spraying is stopped at the first time after a fire disaster is finished, and more intelligence is achieved.

本发明公开了一种智能洒水喷头,包括喷头壳体,所述喷头壳体内开设有进水口,所述进水口内固定连接密封板,所述喷头壳体的底侧固定连接有金属存储箱,所述金属存储箱的外侧壁绕有导热丝,所述金属存储箱内注有低沸点溶液,所述金属存储箱内滑动连接有活塞块,所述活塞块上侧固定连接有活塞杆,所述活塞杆依次穿过金属存储箱、密封板的一端固定连接有滑塞。本发明让预留冷却腔内充满水流紧贴金属存储箱外壁,从出水孔流出带走热量,帮助金属存储箱快速降温,让气体状态下的低沸点溶液重新液化,从而使得活塞块在弹簧弹力的情况下复位,并且带动活塞杆复位,滑塞重新堵住倒锥形开口,从而可以在火灾结束后第一时间停止喷水,更加智能。
