Abstract
Description
Technical Field
[0001] The invention belongs to the field of water film generation, in particular to a fire-proof water film generation device. Background Art
[0002] In many public buildings, such as shopping malls, fireproof rolling doors are often installed in fireproof structural openings, atriums or display windows as fire partitions for fire escape safety. The new law in the current building technical rules stipulates that rolling doors used for fireproof area openings must have a fireproof period of more than one hour to effectively control the fire within the fireproof area. In the event of a fire, the fireproof area can be used to form an effective barrier to prevent the spread of flames, smoke, etc. By sprinkling water, a water film can be formed on the surface of the rolling door. By utilizing the effect of water evaporation when it encounters heat, the water film can absorb and carry away the high temperature generated by the fire, and can isolate the high-temperature smoke generated by the fire, thereby protecting life and property.
[0003] A patent application with publication number CN104722127A discloses a water circulation device of a fireproof water film system, wherein a water storage tank is provided in the water film system, a water supply pump is connected to the water outlet end of the water storage tank, a porous pipe is connected to the water supply pump, a water pump is connected to the water inlet end of the water storage tank, a water collecting tank is connected to the water pump corresponding to the porous pipe, and a filtering unit is connected between the water pump and the water collecting tank; accordingly, when a fire occurs, a water film can be formed on the surface of the iron rolling door or glass to serve as a fireproof partition barrier and prevent the spread of flames, and the water flowing downward on the surface of the iron rolling door or glass can also be recycled and reused to reduce the waste of water resources, and can avoid the situation of no water available in areas where water resources are scarce, and its overall implementation and use are more practical.
[0004] However, the above technical solution still has the following deficiencies in practical application:
[0005] When it is necessary to form a water film on the surface of the iron rolling door, since the surface of the iron rolling door has several protrusions and grooves, the upper and lower sides of these grooves will be blocked by the protrusions, and the water flow is not easy to spray to the flames in the grooves. In the above technical scheme, when the porous tube sprays water, the porous tube is stationary relative to the iron rolling door, so the water outlet direction of the porous tube is too single, and the spraying angle cannot be changed in real time according to the shape of the groove, which may cause the flames to be hidden in the groove, resulting in too many dead angles for spraying and insufficient fire extinguishing, which poses certain safety hazards.

DETAILED DESCRIPTION
[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0034] Embodiment 1: Figure 1-9 As shown, a fire-proof water film generating device according to an embodiment of the present invention comprises a door frame 1, a rolling door 2 is arranged at the front end of the door frame 1, a water storage tank 3 is arranged at the front end of the door frame 1, and a reversing spraying mechanism 6 is arranged at the front end of the door frame 1 for forming a relatively evenly distributed water film on the surface of the rolling door 2;
[0035] The reversing spraying mechanism 6 includes a mounting plate 618 fixedly connected to both ends of the left side of the door frame 1, the front end of the mounting plate 618 is fixedly connected to a first slide bar 610, the first slide bar 610 is slidably connected to a slider 611, the right end of the slider 611 is fixedly connected to a support plate 613, the front end of the support plate 613 is fixedly connected to a limit rod 67, the limit rod 67 is slidably connected to a frame 66, the rear side of the frame 66 is rotatably connected to a first rotating shaft 65, and the right end of the first rotating shaft 65 is fixedly connected to a long tube 63, a plurality of nozzles 64 are arranged on the rear side of the long tube 63, the right end of the water storage tank 3 is connected with the pump body 61, the water outlet end of the pump body 61 is connected with the hose 62, the left end of the hose 62 is connected with the long tube 63, a second connecting rod 616 is rotatably arranged at the front end of the slider 611, the second connecting rod 616 is meshed with the slider 611 for transmission, a first connecting rod 615 is rotatably arranged at the upper end of the second connecting rod 616, the right end of the first connecting rod 615 is rotatably connected with the frame 66, the frame 66 is meshed with the long tube 63 for transmission.
[0036] Specifically, the door frame 1 is installed at the opening of a fireproof structure such as a wall. When a fire occurs, the fire will spread to the iron rolling door 2, so it is necessary to form a water film on the surface of the iron rolling door 2 to block the flame. The pump body 61 can be started to pump out the water in the water storage tank 3, and the water is transported to the long pipe 63 through the hose 62, and sprayed from the nozzle 64 to the surface of the iron rolling door 2 to form a water film on the surface. Then, the slider 611 is driven by the electric control device to move vertically up and down on the first slide bar 610, so that the water film can be formed. The frame 66 moves vertically up and down, so that the long tube 63 moves up and down to expand the longitudinal spraying range, so that the surface of the iron rolling door 2 can be sprayed from top to bottom, and when the slider 611 moves vertically, the meshing transmission method is used to drive the second connecting rod 616 to rotate continuously. Under the action of the second connecting rod 616 and the first connecting rod 615, the frame 66 can form a horizontal reciprocating sliding on the limit rod 67, so that the long tube 63 and the nozzle 64 can be reciprocated left and right to spray the nozzle 64. The spray dead angle caused by the gap between the nozzles 64 can be reduced to a certain extent by changing the direction of the horizontal direction. When the frame 66 moves up and down, the intermittent meshing transmission method is used to make the long tube 63 rotate intermittently, and the first rotating shaft 65 and the frame 66 are provided with a torsion spring to make the first rotating shaft 65 recover after rotation, so that the inclination angle of the nozzle 64 changes. Since the surface of the iron rolling door is provided with multiple protrusions, there will be grooves between the multiple protrusions. When the spray direction of the nozzle 64 is single, it is impossible to When flames appear on the upper and lower sides of the groove, these flames will be covered by the protrusion of the iron rolling door 2, making it difficult for the water flow to reach the covered flames, resulting in incomplete fire extinguishing, which poses certain safety hazards. By using the above-mentioned reversible spraying mechanism 6, the angle of the nozzle 64 can be changed when the nozzle 64 passes through the groove and protrusion of the iron rolling door 2. The nozzle 64 changes from facing downward to facing upward, and the upper and lower sides of the groove of the iron rolling door 2 can be sprayed. The spraying trajectory is as follows Fig. 9 As shown, the flames in the grooves of the iron rolling door 2 can be extinguished, and uniform spraying can be achieved, so that a multi-directional water flow spraying effect can be achieved on the surface of the iron rolling door 2, so that a relatively evenly distributed water film is formed on the surface of the iron rolling door 2 to block the spread of the fire, and the spray direction of the nozzle 64 can be reciprocated in the longitudinal, transverse and inclined angles, so that the water flow can be sprayed to various areas of the iron rolling door 2, and the flames in the grooves of the iron rolling door 2 can be sprayed, thereby greatly reducing the fire extinguishing blind spots on the surface of the iron rolling door 2, and, compared with the existing method of setting multiple sprinkler heads, the number of sprinkler heads is reduced, and there is no need for too many electronic control equipment to complete the direction adjustment, which is also convenient for maintenance when a fault occurs.
[0037] like Figure 2 and Figure 4As shown, the upper end of the upper mounting plate 618 is fixedly connected to the first motor 617 , the output end of the first motor 617 is fixedly connected to the first reciprocating screw 69 , and the first reciprocating screw 69 is threadedly connected to the slider 611 .
[0038] Specifically, by driving the first reciprocating screw rod 69 to rotate through the first motor 617, the slider 611 can slide on the first slide rod 610, and the slider 611 can make a longitudinal reciprocating motion, so that the long tube 63 can move longitudinally reciprocatingly, and the nozzle 64 can spray the iron rolling door 2 from top to bottom, thereby forming a water film at different heights on the surface of the iron rolling door 2.
[0039] like Figure 2 As shown, the first gear 612 is fixedly connected to the connection between the second connecting rod 616 and the slider 611 , and the first rack 68 is fixedly connected to the left end of the mounting plate 618 , and the first rack 68 and the first gear 612 are meshed with each other.
[0040] Specifically, when the slider 611 slides up and down, the second connecting rod 616 continues to rotate under the action of the first rack 68 and the first gear 612, so that the frame 66 can form a horizontal reciprocating sliding on the limiting rod 67, and the long tube 63 and the nozzle 64 can be moved back and forth left and right to change the spraying direction of the nozzle 64 laterally, which can reduce the spraying dead angle caused by the gap between the nozzles 64 to a certain extent.
[0041] like Figure 3 As shown, the right end of the long tube 63 is fixedly connected to the second rotating shaft 620, the right end of the second rotating shaft 620 is rotatably connected to the frame 66, the second rotating shaft 620 is sleeved with a first torsion spring 621, the left end of the first torsion spring 621 is fixedly connected to the frame 66, the right end of the first torsion spring 621 is fixedly connected to the second rotating shaft 620, the right end of the second rotating shaft 620 is sleeved with a second gear 619, and the second rack 614 is installed on the right side of the front end of the door frame 1 by bolts, the second gear 619 and the second rack 614 are meshed with each other, and the tooth blocks of the second rack 614 are intermittently distributed.
[0042] Specifically, when the frame 66 moves up and down, the nozzle 64 in the initial state faces downward. When the second gear 619 contacts the second rack 614, the second rotating shaft 620 can be rotated to rotate the nozzle 64 upward. When the second gear 619 does not contact the second rack 614, the angle of the nozzle 64 can be restored under the action of the first torsion spring 621, and the nozzle 64 continues to face downward, so that the nozzle 64 can form a reciprocating rotation. Since the surface of the iron rolling door is provided with a plurality of protrusions, there will be grooves between the plurality of protrusions. When the nozzle 64 When the spray direction is too single, it is impossible to spray the upper and lower surfaces of the groove. When flames appear on the upper and lower surfaces of the groove, these flames will be covered by the protrusion of the iron rolling door 2, making it difficult for the water flow to reach the covered flames, resulting in incomplete fire extinguishing, which poses certain safety hazards. The angle of the nozzle 64 can be changed when the nozzle 64 passes through the groove and the protrusion of the iron rolling door 2. The nozzle 64 changes from a downward direction to an upward direction, and the upper and lower surfaces of the groove of the iron rolling door 2 can be sprayed. The spraying trajectory is as follows Fig. 9 As shown, the flame at the groove of the iron rolling door 2 is extinguished, and uniform spraying can be achieved.
[0043] Embodiment 2: Figure 1 and Figure 6 As shown, compared with Example 1, another embodiment of the present invention is: a water flow filtering and collecting mechanism 7 for recycling water is arranged inside the water storage tank 3; the water flow filtering and collecting mechanism 7 includes a filter screen 714 fixedly connected to the inner cavity wall of the water storage tank 3, and a plurality of through holes 4 are arranged at the upper end of the water storage tank 3.
[0044] Specifically, the through hole 4 can be used to allow the spraying water to flow into the water storage tank 3, and after being filtered by the filter screen 714, it can be recycled.
[0045] like Figure 1 , Figure 5-Figure 7 As shown, both ends of the water tank 3 are fixedly connected with the second sliding rod 79, the second sliding rod 79 is slidably connected with the threaded block 713, the lower end of the threaded block 713 is fixedly connected with the scraper 711, the water tank 3, the right end of the water tank 3 is fixedly connected with the second motor 715, the output end of the second motor 715 is fixedly connected with the second reciprocating screw 710, and the second reciprocating screw 710 is threadedly connected with the threaded block 713.
[0046] Specifically, the second reciprocating screw rod 710 is driven to rotate continuously by the second motor 715, so that the scraper 711 can slide left and right, so that the scraper 711 can scrape the impurities on the surface of the filter screen 714 to both sides, so as to achieve the centralized placement of impurities and facilitate the subsequent collection work.
[0047] like Figure 5 , Figure 6 , Figure 8As shown, both ends of the water tank 3 are slidably connected with an L-shaped rod 73, the lower end of the L-shaped rod 73 is fixedly connected with a compacting block 72, the grooves at both ends of the filter screen 714 are plugged with collecting boxes 71, and both ends of the water tank 3 are rotatably provided with a third rotating shaft 74, the front end of the third rotating shaft 74 is sleeved and fixedly connected with the third rotating shaft 74, the lower end of the third rotating shaft 74 is rotatably provided with a fourth connecting rod 78, the lower end of the fourth connecting rod 78 is rotatably connected with the compacting block 72, the rear end of the third rotating shaft 74 is sleeved with a second torsion spring 75, the rear end of the second torsion spring 75 is fixedly connected to the water tank 3, and the front end of the second torsion spring 75 is fixedly connected to the third rotating shaft 74, the upper end of the scraper 711 is fixedly connected with a third rack 712, and the front end of the third rotating shaft 74 is sleeved and fixedly connected with a third gear 76.
[0048] Specifically, when the scraper 711 moves laterally and is about to reach the edge of the collecting box 71, the third rack 712 drives the third gear 76 to rotate, so that the third connecting rod 77 and the fourth connecting rod 78 rotate, so that the angle between the two changes, so that the compacting block 72 slides downward, and while the compacting block 72 moves downward, the impurities are pushed into the collecting box 71, and then the scraper 711 continues to move, and the compacting block 72 continues to descend and fits with the bottom of the collecting box 71, so that the impurities can be compacted and the volume of the impurities can be reduced. Then the scraper 711 moves in the opposite direction of the scraping direction under the threaded transmission mode. When the gear rack used to drive the third connecting rod 77 and the fourth connecting rod 78 to rotate is no longer in contact, the third rotating shaft 74 can be restored under the action of the second torsion spring 75, so that the compacting block 72 is lifted. After multiple cycles, the impurities can be scraped into the collecting box 71 and compacted to reduce the volume of the impurities and reduce the space occupied by the subsequent impurities when they are discarded, which is more convenient.
[0049] like Figure 1 As shown, a box door 5 is arranged at the front end of the water storage tank 3, and a water injection pipe is arranged at the left end of the water storage tank 3.
[0050] Specifically, personnel can manually open the box door 5, take out the collection box 71, collect the impurities, and then use the water injection pipe to inject water into the water storage tank 3 to complete the removal of impurities and water injection.
[0051] like Figure 1 As shown, a sealing pad is provided at the edge of the door 5, and a door lock is provided at the front end of the door 5.
[0052] Specifically, the door 5 can be locked by using a door lock to prevent the door 5 from being opened by mistake, and the sealing gasket can prevent water from overflowing, thereby ensuring the sealing of the water storage tank 3.
[0053] Working principle: when a fire occurs and a water film needs to be formed on the surface of the iron rolling door 2, the pump body 61 pumps out the water in the water tank 3, transports it to the long tube 63 through the hose 62, and sprays it from the nozzle 64 to the surface of the iron rolling door 2, so that a water film is formed on its surface. The slider 611 is moved vertically up and down by means of a screw transmission to expand the longitudinal spraying range, so that the surface of the iron rolling door 2 can be sprayed from top to bottom. The connecting shaft between the slider 611 and the second connecting rod 616 is rotated by means of a gear rack transmission. The second connecting rod 616 is continuously rotated, so that the frame body 66 can form a horizontal reciprocating sliding on the limit rod 67, so that the long tube 63 and the nozzle 64 are reciprocated left and right to change the spraying direction of the nozzle 64 laterally, which can reduce the spraying dead angle caused by the gap between the nozzles 64 to a certain extent. When the frame body 66 moves up and down, the gear rack transmission method is used to make the second rotating shaft 620 intermittently Rotation can make the nozzle 64 form a reciprocating rotation, that is, when the nozzle 64 passes through the groove and the protruding position of the iron rolling door 2, the angle of the nozzle 64 changes, and the nozzle 64 changes from downward to upward, so that the upper and lower surfaces of the groove of the iron rolling door 2 can be sprayed, thereby achieving a multi-directional water flow spraying effect on the surface of the iron rolling door 2, so that a relatively evenly distributed water film is formed on the surface of the iron rolling door 2 to block the spread of the fire, and the spraying direction of the nozzle 64 can be reciprocated in a longitudinal, transverse and inclined angle, so that the water flow can be sprayed to various areas of the iron rolling door 2, and the flames in the groove of the iron rolling door 2 can be sprayed, thereby greatly reducing the fire extinguishing blind spots on the surface of the iron rolling door 2, and compared with the existing method of setting multiple sprinkler heads, the number of sprinkler heads is reduced, and there is no need for too much electrical control equipment to complete the direction adjustment, which reduces the overall cost and is also convenient for maintenance when a fault occurs;After the water flow is sprayed, it flows into the water storage tank 3 through the through hole 4 at the bottom of the water storage tank 3, and the water flow is filtered by the filter screen 714. The second motor 715 is started to drive the second reciprocating screw rod 710 to rotate continuously, so that the scraper 711 can slide left and right, so that the scraper 711 scrapes the impurities on the surface of the filter screen 714 to both sides, and the impurities are scraped into the collection box 71. The third rack 712 drives the third gear 76 to rotate to rotate the third connecting rod 77 and the fourth connecting rod 78 to change the angle between the two, so that the compacting block 72 slides downward, and while the compacting block 72 moves downward, the impurities are pushed into the collection box 71, and then the scraper 711 continues to move, and the compacting block 72 continues to descend and fits the bottom of the collection box 71, so that the impurities can be compacted and the volume of the impurities can be reduced. 11 moves in the opposite direction of the scraping direction in the screw transmission mode. When the gear rack used to drive the third connecting rod 77 and the fourth connecting rod 78 to rotate is no longer in contact, the third rotating shaft 74 can be restored under the action of the second torsion spring 75, so that the compacting block 72 is lifted. After multiple cycles, the impurities can be scraped into the collection box 71 and compacted to reduce the volume of the impurities and reduce the space occupied by the subsequent impurities when discarded, which is more convenient. Therefore, the water flow used for spraying can be collected and filtered, which can be recycled and save resources. In addition, the impurities attached to the surface of the filter screen 714 can be automatically scraped, so that the impurities are concentrated and accumulated in the collection boxes 71 on both sides.
