Abstract
A prostration typed steel air fog fire resisting shutter is provided with a shutter body, a shutter body driving mechanism and a left prostration lead rail and a right prostration lead rail, wherein, the left and the right sides of shutter body are matched with the left and the right prostration lead rails; the end of the shutter body is connected with a wound roll of the shutter body driving mechanism. The utility model is characterized in that a water spraying structure is arranged at least in one of the left and the right prostration lead rails, the water spraying port of the water spraying structure is toward the upper surface of the shutter body. The prostration typed steel air fog fire resisting shutter of the utility model discloses can prevent the damage of the shutter body caused by the high temperature and thus, the function of the shutter to interdict the trace flue is ensured.
Description
Technical field
The utility model relates to a kind of rolling door, especially a kind of fire curtain.
Background technology
China's utility model patent discloses a kind of horizontal fire resistance rolling shutter door for No. 97208521.1, and curtain body one end of this rolling door is fixed in the curtain body and drives on the reel, and its dual-side matches with the left and right guide groove that level is installed.This rolling door can be installed in places such as escalator mouth, and when breaking out of fire, the user can close rolling door, utilizes the curtain body with the sealing of escalator mouth, reaches the purpose on the fiery road of blocking-up.In addition, Chinese utility model patent also discloses a kind of horizontal compound steel fire resistance rolling shutter door for No. 97220889.5, and the main distinction of this rolling door and above-mentioned patent is that its curtain body drives structure is different.These two kinds of existing products all can utilize the curtain body that blocking-up is implemented on fiery road, but use in discovery in reality, and when the intensity of a fire duration big or fire was longer, curtain was known from experience because of too high breaking-up of heating up, thus the function of forfeiture fire prevention partition.Therefore, in order to ensure security against fire, be necessary it is done further to improve.
The utility model content
The purpose of this utility model is that above-mentioned existing fire curtain is improved, and the better horizontal steel of a kind of fireproof performance steam fog fire curtain is provided.
Horizontal steel steam fog fire curtain of the present utility model has roller shutter curtain body, curtain body driving mechanism and the left and right flat guide rail that crouches, the left and right side of roller shutter curtain body matches with the left and right flat guide rail that crouches respectively, the end of roller shutter curtain body is connected with the reel of curtain body driving mechanism, it is characterized in that left and right at least flat one of guide rail that crouches is provided with water spraying structure, the water jet of described water spraying structure is towards the upper surface of roller shutter curtain body.When using steam fog of the present utility model to prevent fires flat horizontal roll curtain, can be earlier above-mentioned water spraying structure and user's water supply pipe be joined, and relative set automatic or manual water valve.In case breaking out of fire, the user can close roller shutter curtain body, with the sealing of fiery road.Simultaneously, the user can open water valve, allows tap water enter water spraying structure, is sprayed to the upper surface of roller shutter curtain body again by the water jet of water spraying structure.The tap water that is sprayed on roller shutter curtain body upper surface will accumulate on this curtain body, when the curtain body is subjected to the baking of flame and heats up, stockpile in the tap water of curtain surface and also can be subjected to thermal evaporation and form steam fog, the corresponding part heat of taking away the curtain body.Under the continuous spray and evaporation of current, the temperature of curtain body will can not surpass 100 ℃, thereby guarantee that the curtain body can be because of too high breaking-up of heating up.In the utility model, above-mentioned water spraying structure can only be arranged on a left side flat crouch guide rail or the right flat guide rail that crouches (as when the curtain body is narrower), but also can be arranged on simultaneously on the left and right flat guide rail that crouches.Set water spraying structure can be the water pipe that has delivery port, also can be by the water pipe jet head sets that is connected.Stockpile tap water for the ease of upper surface, can also make the curtain sheet upper surface of roller shutter curtain body have recess (as groove etc.) by selecting the contour structures of curtain sheet for use at the curtain body.Curtain body drives structure in the utility model is the drives structure form of the above-mentioned existing fire curtain of adopting by reference directly.Simultaneously, can open and close neatly, can also set up cylinder at the left and right side of curtain body, and in left and right guide rail, set up the structures such as transmission chain that match with this cylinder, to reduce the kinetic friction force of curtain body when opening and closing in order to make roller shutter curtain body.
Compared with the aforementioned existing similar products, horizontal steel steam fog fire curtain of the present utility model can prevent roller shutter curtain body because of too high breaking-up of heating up, thereby can guarantee the function on the blocking-up fire road of roller shutter.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

The specific embodiment
Shown in Fig. 1～4, horizontal steel steam fog fire curtain in the present embodiment has roller shutter curtain body 1, curtain body driving mechanism and the left and right flat guide rail 3,4 that crouches, the left and right side 5,6 of roller shutter curtain body 1 matches with the left and right flat guide rail 3,4 that crouches respectively, the end of roller shutter curtain body 1 is connected with the reel 2 of curtain body driving mechanism, the left and right flat guide rail 3,4 that crouches is provided with water spraying structure 8,9, and the water jet of this water spraying structure 8,9 is towards the upper surface of roller shutter curtain body 1.In the present embodiment, the water spraying structure 8,9 that is arranged on the left and right flat guide rail that crouches is the sparge pipe form that offers hole for water spraying.The curtain sheet upper surface of the roller shutter curtain body 1 that is adopted has recess 10.Simultaneously, left and right side at roller shutter curtain body is provided with cylinder 11, the mandrel of described cylinder 11 is fixed on the roller shutter body body 1, be provided with the driving chain 7 that is in transmission connection with curtain body driving mechanism in the left and right flat guide rail 3,4 that crouches, the cylinder 11 that is arranged at the left and right side of roller shutter curtain body is placed on respectively on the interior driving chain 7 of the left and right flat guide rail that crouches.In the process of the flat horizontal roll curtain in using present embodiment, when breaking out of fire, roller shutter can be closed, and introduce current by the waterpipe jointing that links to each other with water spraying structure 8,9.The current of introducing are sprayed at the upper surface of roller shutter curtain body 1 from water spraying structure 8,9, and roller shutter curtain body 1 is implemented cooling.Simultaneously, the part current also can stockpile in the recess 10 of curtain body upper surface.The current that spray and stockpile on roller shutter curtain body can flash to steam fog when the curtain body is subjected to flame baking, take away the heat on the curtain body, and the curtain body is unlikely to be burnt out thereby make, and guarantees its fire-proof function.In addition, in the opening-closing process of curtain body, set driving chain 7 and cylinder 11 can reduce its kinetic friction force effectively, allow the opening and closing neatly of curtain body.
