Description

Technical Field

[0001] The utility model relates to the technical field of fire protection engineering, in particular to a smoke isolation door for fire protection engineering. Background Art

[0002] A smoke-tight door refers to a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with a certain fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, smoke-tight doors can also prevent the spread of fire and smoke. They can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel.

[0003] The China Patent Network discloses a smoke-proof door for fire protection engineering, and its patent publication number is "CN221277589U". It mainly has high fire resistance and high performance sealing by setting a fireproof sealing strip, and the surface is made of impregnated silicone rubber, so that the fireproof sealing strip can be used in high temperature environments without affecting its own sealing performance, which is conducive to blocking most of the smoke leaking in from the door gap, improving the smoke-proof effect of the smoke-proof door, and a small amount of smoke passing through the smoke-proof door is driven by the wind fan to enter the interior of the installation groove from the smoke inlet, and the cold water is supplied to the outside of the water inlet pipe. The input cooling trough is convenient for cooling the installation trough, and most of the smoke particles are adsorbed by the smoke particle adsorption plate, which is beneficial to reducing the damage of smoke to the environment, and the smoke after preliminary filtration is discharged from the external exhaust pipe by the smoke exhaust pipe, thereby realizing the smoke exhaust function of the smoke barrier door. However, it has a disadvantage in use, that is, the sealing strip will inevitably be damaged due to aging, and daily inspection and replacement are required by staff, but the sealing strip itself is difficult to remove at the angle gap, which affects personnel inspection and replacement. Based on this, the utility model proposes a new smoke barrier door for fire protection engineering. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 , a smoke barrier door for fire protection engineering, includes a wall 1, a sealing door 2 is installed on the wall 1, and a sealing block 201 is fixedly connected to the connection between the sealing door 2 and the wall 1, and a groove 205 is opened on the sealing block 201, and a sealing strip 204 is slidably connected in the groove 205, and a side wall of the sealing strip 204 is fixedly connected to a connecting plate 202, and the connecting plate 202 is fixedly connected to the sealing block 201 by a fixing screw 203, and a handle 3 is fixedly connected to the opening side of the sealing door 2. The sealing strip 204 is divided into two layers, the outer layer of the sealing strip 204 is made of absorbent cotton material, and the inner layer of the sealing strip 204 is filled with hydrogenated polymer resin material. It should be noted that the double-layer design of the sealing strip 204 can not only realize the function of absorbing water to fill the gap, but also ensure that the sealing strip 204 will not be easily damaged, resulting in a poor sealing effect.

[0022] The side wall of the wall 1 is fixedly connected to the water tank 4, and the side wall of the water tank 4 is fixedly connected to the water inlet pipe 101. The water inlet pipe 101 is fixedly connected to the lower end of the pressure cylinder 5 away from the water tank 4. The side wall of the pressure cylinder 5 is fixedly connected to the water outlet pipe 102. The end of the water outlet pipe 102 away from the pressure cylinder 5 is fixedly connected to the nozzle 103. The nozzle 103 is fixedly connected to the lower end of the transmission plate 12. The upper end of the water tank 4 is fixedly connected to the pressure cylinder 5. The inner wall of the pressure cylinder 5 is slidably connected to the piston rod 6. The end of the piston rod 6 away from the pressure cylinder 5 is fixedly connected to the transmission plate 12. The side wall of the wall 1 is fixedly connected to the mounting plate 7. The upper end of the mounting plate 7 is installed with a motor 8. The upper end of the mounting plate 7 is fixedly connected to the front baffle 9. The output shaft of the motor 8 is fixedly connected to the reciprocating screw 10, and the transmission plate 12 is threadedly connected to the axial outer wall of the reciprocating screw 10. One end of the reciprocating screw 10 is rotatably connected to the front baffle 9 and the other end is rotatably connected to the rear baffle 13. A limiting rod 11 is fixedly connected to the side wall of the front baffle 9, and the end of the limiting rod 11 away from the front baffle 9 is fixedly connected to the rear baffle 13. The limiting rod 11 passes through the sliding connection transmission plate 12. It should be noted that a one-way valve is provided in the water outlet pipe 102 and the water inlet pipe 101 to avoid backflow of water. It should be noted that the spray port of the nozzle 103 is set at an angle, so as to ensure that the water flow is sprayed onto the sealing door 2 and the sealing strip 204 to the greatest extent.

[0023] The specific usage method of the device is as follows: when a fire occurs, the motor 8 starts automatically. When the motor 8 works, it will drive the reciprocating screw 10 to rotate. When the reciprocating screw 10 rotates, it will drive the transmission plate 12 to perform reciprocating linear motion. When the transmission plate 12 moves, it will drive the piston rod 6 to move. When the piston rod 6 moves, a cavity will be formed in the pressure cylinder 5. Under the action of atmospheric pressure, the water in the water tank 4 will be sucked into the pressure cylinder 5 through the water outlet pipe 102. When the piston rod 6 moves in the opposite direction, the water flow in the pressure cylinder 5 will be squeezed into the nozzle 103 and sprayed out. At the same time, the nozzle 103 will move back and forth with the transmission plate 12 so that the water flow can be evenly sprayed to various parts of the sealed door 2.

[0024] Further water flow will be absorbed by the sealing strip 204 while cooling the sealed door 2. The sealing strip 204 will expand after absorbing moisture, so that the sealing strip 204 can completely seal and fill the gap between the wall 1 and the sealed door 2, preventing thick smoke from seeping into the inside of the sealed door 2 through the gap. If the sealing strip 204 needs to be replaced, it is only necessary to remove the fixing screws 203, and the sealing strip 204 can be pulled out of the sealing block 201 for replacement.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
