Detailed Description
In order to make the purpose, technical solution and advantages of the present technical solution clearer, the present technical solution is further described in detail below with reference to specific embodiments. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present teachings.
Referring to fig. 1-6, the present invention provides a technical solution: a fire-proof curtain structure for a tunnel comprises a rolling curtain box 1, a rotating shaft 2 and a fire-proof rolling curtain 3, wherein the rotating shaft 2 is arranged in the rolling curtain box 1, a first end part of the rotating shaft 2 is fixedly connected with an output end of a motor 4, a second end part of the rotating shaft 2 is rotatably connected with the inner wall of the rolling curtain box 1, the top of the fire-proof rolling curtain 3 is fixedly connected with the rotating shaft 2, guide rails 5 which are vertically arranged are arranged below the rolling curtain box 1 and positioned on two sides of the fire-proof rolling curtain 3, and the fire-proof rolling curtain 3 can slide up and down along the guide rails 5; the front side of fire prevention roll up curtain 3 is equipped with inlet tube 6, inlet tube 6 and 1 fixed connection of roll up curtain case, be equipped with a plurality of outlet pipes 7 on the inlet tube 6, be equipped with first shower nozzle 8 on the outlet pipe 7, first shower nozzle 8 is equipped with vertical tye 9 towards fire prevention roll up curtain 3 on the fire prevention roll up curtain 3, be equipped with the closing plate 10 that the level set up between the bottom of two guide rails 5, closing plate 10 and guide rail 5 fixed connection, the top surface of closing plate 10 is equipped with recess 11, the top surface of closing plate 10 and the both sides of position recess 11 all are equipped with inclined plane 12.
Referring to fig. 2, fig. 2 is an isometric view of the present invention after being installed on a wall, at this time, the fire-proof rolling shutter 3 is in a closed state, and the bottom of the fire-proof rolling shutter 3 is located in the groove 11 of the sealing plate 10. When a fire disaster happens, water in the water inlet pipe 6 passes through the water outlet pipe 7 and then is sprayed to the fireproof rolling screen 3 through the first spray head 8, the water sprayed to the fireproof rolling screen 3 can flow downwards along the water flowing groove 9 on the front surface, and in the process, the water can cool the fireproof rolling screen 3. When water flows to the bottom of the fire-proof rolling screen 3, the water flows to the sealing plate 10 and then flows into the groove 11 along the inclined surface 12, and the gap between the groove 11 and the bottom of the fire-proof rolling screen 3 is completely filled and sealed. Consequently when dense cigarette is close to the bottom of fire prevention curtain, can be blockked by the water in the closing plate 10, dense cigarette can not pass the gap entering fire prevention roll of curtain 3 at the back of bottom, the utility model discloses have good cigarette ability that separates, can ensure the health of the personnel at the back of fire prevention roll of curtain 3. Referring to fig. 3, when the fire-proof rolling shutter 3 needs to be opened to enable a person to escape, the motor 4 works to drive the rotating shaft 2 in the rolling shutter box 1 to rotate, the fire-proof rolling shutter 3 rises along the guide rail 5, the fire-proof rolling shutter 3 enters an opened state, and the person can rapidly pass through the fire-proof rolling shutter 3 to reach a safe area.
Referring to fig. 1, the width of the top of the launder 9 is greater than that of the bottom, so that water entering the launder 9 flows out from the bottom more quickly and reaches the bottom of the fire-proof roller shutter 3 more quickly; the three groups of the water flowing grooves 9 are respectively positioned at the left end, the middle part and the right end of the fireproof rolling screen 3, so that water on the front surface of the fireproof rolling screen 3 can uniformly flow onto the sealing plate 10, and the condition that one side of water is more and one side of water is less can not occur.
Referring to fig. 5, the bottom of the fire-proof rolling screen 3 is provided with a rubber strip 13, and the rubber strip 13 can increase the sealing performance of the bottom of the fire-proof rolling screen 3, and cooperate with the water flowing into the groove 11 to further prevent the dense smoke from passing through the bottom gap.
Referring to fig. 1, a second nozzle 14 is disposed on the water outlet pipe 7, and the second nozzle 14 is opposite to the first nozzle 8. The second spray head 14 can spray water outwards to prevent fire spreading towards the fire curtain 3.
Referring to fig. 1 and 5, a reflective strip 15 is disposed on the front side of the fire-proof rolling curtain 3, and a thermal insulation layer 16 is disposed on the rear side of the fire-proof rolling curtain 3. The reflective strips 15 can facilitate people needing to escape and passing vehicles to quickly find the position of the fireproof rolling screen 3, and the heat insulation layer 16 can slow down the time for heat on the front side of the fireproof rolling screen 3 to be conducted to the rear side of the fireproof rolling screen 3.
The utility model discloses a first shower nozzle 8 spouts to fire prevention roll screen 3 water spray, and water can play the effect of cooling to fire prevention roll screen 3, then flows into recess 11 along inclined plane 12 to it is sealed to fill up the gap between the bottom of recess 11 and fire prevention roll screen 3, when dense cigarette is close to the bottom of fire prevention screen, can be blockked by the water in the closing plate 10, and dense cigarette can not pass the gap entering fire prevention roll screen 3's of bottom back, the utility model discloses have good cigarette ability that separates, can ensure fire prevention roll screen 3 the back personnel's of health. The rubber strip 13 may further prevent dense smoke from passing through the bottom gap. The second spray head 14 can spray water outwards to prevent the fire from spreading in the direction of the fire-proof rolling screen 3. The reflective strips 15 can facilitate finding the position of the fire-proof roller shutter 3, and the heat insulation layer 16 can slow down the heat conduction time.
The working principle is as follows: when a fire disaster happens, water in the water inlet pipe 6 passes through the water outlet pipe 7 and then is sprayed to the fireproof rolling screen 3 through the first spray head 8, the water sprayed to the fireproof rolling screen 3 can flow downwards along the water flowing groove 9 on the front surface, and in the process, the water can cool the fireproof rolling screen 3. When water flows to the bottom of the fire-proof rolling screen 3, the water flows to the sealing plate 10 and then flows into the groove 11 along the inclined surface 12, and the gap between the groove 11 and the bottom of the fire-proof rolling screen 3 is completely filled and sealed. Consequently when dense cigarette is close to the bottom of fire prevention curtain, can be blockked by the water in the closing plate 10, dense cigarette can not pass the gap entering fire prevention roll of curtain 3 at the back of bottom, the utility model discloses can ensure the health of the personnel at the back of fire prevention roll of curtain 3. When the fire-proof rolling shutter 3 needs to be opened to enable people to escape, the motor 4 works to drive the rotating shaft 2 in the rolling shutter box 1 to rotate, the fire-proof rolling shutter 3 ascends along the guide rail 5, the fire-proof rolling shutter 3 enters an opened state, and the people can rapidly reach a safe area through the fire-proof rolling shutter 3.
The foregoing is only a preferred embodiment of the present invention, and many variations can be made in the specific embodiments and applications of the present invention by those skilled in the art without departing from the spirit of the present invention.
