Description

Technical Field

[0001] The utility model relates to the technical field of airtight doors, in particular to a fireproof and moisture-proof airtight door. Background Technique

[0002] The airtight waterproof door is used in the passage from the underground main substation and the main drainage pump room to the bottom of the shaft. It is easy to close to prevent the sudden intrusion of water. A fire door refers to a door that can meet the requirements of fire resistance stability, integrity, and heat insulation within a certain period of time. It is a fireproof partition with a certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, fire doors also have the functions of preventing the spread of fire and smoke diffusion. They can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. However, at present, the waterproof airtight door does not have the function of fire prevention.

[0003] For example, a hermetic waterproof and fireproof door disclosed in Chinese Patent CN208220567U connects the door body and the door frame through hinges. The glass plate is borosilicate glass with a low coefficient of thermal expansion and good thermal shock resistance, effectively blocking flames, isolating high temperatures and harmful gases. The glass plate at the upper end of the door body can be used to check the situation inside and outside the room at any time. Turn the handwheel to open the door body. One side of the upper end of the door frame is equipped with a support, and the support is connected to the door closer through a connecting rod. When the door body is opened, it can be automatically closed by compression and release, ensuring that after the door body is opened, it can be accurately and timely closed to the initial position. The sealing strip on the outer wall of the stainless steel door panel tightly connects the door body and the door frame, with good tensile strength, heat resistance and aging resistance, playing an important role in waterproof sealing. The outer waterproof layer is a propyl acrylate layer, which is environmentally friendly and non-toxic, with good corrosion resistance, durability, impermeability, density and extremely high adhesion, thus achieving the waterproof effect. The fireproof board inside the stainless steel door panel is a perlite fireproof board, and the outer wall of the fireproof board is coated with an epoxy resin fireproof coating layer, which is natural, environmentally friendly, moisture-proof and corrosion-resistant, with good heat insulation and heat preservation performance. The centrifugal glass wool board is wrapped with non-woven fabric on the outside, and can maintain good heat insulation performance in both high-temperature and low-temperature environments, with a low thermal conductivity, achieving the flame retardant effect. The surface grid board is welded to the stainless steel door panel, and a reinforcing rib is installed below the centrifugal glass wool board to keep the shape of the door body stable and not deformed, and it can bear a large load.

[0004] However, in the prior art, during the use of fire doors, the sound insulation layer of airtight doors is usually poor, affecting the airtight effect of airtight doors.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 5 , the present invention provides a technical solution: Embodiment

[0027] A fireproof and moisture-proof sealed door includes a soil base surface 1. An opening and closing structure is installed on the top of the soil base surface 1. An encapsulation structure is connected inside the opening and closing structure. A door body structure is installed inside the encapsulation structure.

[0028] The door body structure includes a sound insulation unit and a fireproof and moisture-proof unit. The sound insulation unit includes a sound insulation cotton 303. Installation holes are formed on the front surface of the sound insulation cotton 303. A spring 304 is installed inside the installation holes. A honeycomb board 305 is connected to the front surface of the sound insulation cotton 303. The fireproof and moisture-proof unit includes a rock wool board 301. An aerogel felt 302 is installed on the front surface of the rock wool board 301. A keel 306 is arranged on the front surface of the aerogel felt 302. A geomembrane 307 is installed on the front surface of the keel 306.

[0029] One end of the back surface of the spring 304 is fixedly connected to the front surface of the aerogel felt 302. One end of the front surface of the spring 304 is fixedly connected to the honeycomb board 305. The back surface of the sound insulation cotton 303 is fixedly connected to the aerogel felt 302. The front surface of the honeycomb board 305 is fixedly connected to one side of the back surface of the keel 306.

[0030] Through the setting of the door body structure, by installing the sound insulation cotton 303 and the spring 304, the sound insulation cotton 303 is used to isolate noise. At the same time, the spring 304 is used to vibrate under the influence of noise, which can consume the energy transmitted by sound waves. At the same time, the honeycomb board 305 is used to refract and absorb sound waves, which can achieve a better sound insulation effect. At the same time, the rock wool board 301 and the aerogel felt 302 are used for double-layer fireproof and heat insulation, and the geomembrane is used for moisture-proof, so as to have a better sealing, fireproof and moisture-proof effect.

[0031] Through the arrangement of the rock wool board 301 and the aerogel felt 302, heat insulation and fire prevention can be carried out on the fire and the temperature generated by the fire. At the same time, in the case of noise, while the sound insulation cotton 303 absorbs and isolates the sound waves, the potential energy of the sound waves vibrating in the air drives the spring 304 to vibrate. During the vibration of the spring 304, the vibration energy transmitted by the sound waves can be effectively consumed. At the same time, when the sound waves are transmitted, the honeycomb board 305 can refract and absorb the sound waves, thereby effectively enhancing the sound insulation effect of the sealed door. At the same time, the keel 306 can effectively enhance the compressive resistance and anti-deformation ability of the sealed door. After that, the geomembrane 307 can make the sealed door effectively waterproof and moisture-proof. Embodiment

[0032] On the basis of Embodiment 1, the encapsulation structure includes a sealing frame 201. A front plate 202 is installed on the front of the sealing frame 201. A handle 203 is installed near the right side in the middle of the front of the front plate 202. Limiting strips 204 are installed at the top and bottom of the sealing frame 201. A back plate 205 is fixedly installed on the back of the sealing frame 201. The inside of the sealing frame 201 is fixedly connected to the outer surfaces of the rock wool board 301, the aerogel felt 302, the sound insulation cotton 303, the honeycomb board 305, the keel 306, and the geomembrane 307. The back of the front plate 202 is fixedly connected to the front of the geomembrane 307. The front of the back plate 205 is fixedly connected to the back of the rock wool board 301.

[0033] The opening and closing structure includes a door rail 101. An extension plate 102 is fixedly installed in the middle of the left side at the bottom of the door rail 101. A limiting plate 103 is fixedly installed at one end of the extension plate 102 away from the door rail 101. A rotating part 104 is fixedly installed in the middle of the right side on the front of the door rail 101. A lock plate 105 is installed in the middle of the outer surface of the rotating part 104. The inside of the door rail 101 is slidably connected to the outer surface of the sealing frame 201. One end of the lock plate 105 away from the rotating part 104 is clamped with the handle 203.

[0034] Through the arrangement of the encapsulation structure and the opening and closing structure, by pulling the handle 203, the sliding of the sealing frame 201 inside the door rail 101 can be driven, as well as the sliding connection between the limiting strip 204 and the convex groove opened inside the door rail 101, so as to complete the sealing opening and closing of the sealed door. In addition, the installation of the lock plate 105 can cooperate with the handle 203 to make the sealing closing effect of the sealed door better.

[0035] When the airtight door is in use, by pulling the handle 203, the airtight door and the sealing frame 201 are driven to slide inside the door rail 101, so that the right side of the sealing frame 201 abuts against the right end inside the door rail 101. At the same time, the locking plate 105 is engaged with the handle 203 to seal the airtight door. During the sliding process, the sliding of the limiting strip 204 inside the convex chute provided inside the door rail 101 can further enhance the sealing effect of the airtight door. When opening the door, the limiting plate 103 is used to limit the sliding of the airtight door to prevent the door body from tipping over due to excessive sliding. The rotating member 104 can be used to rotate the locking plate 105 to the front side to prevent collision with the locking plate 105 when entering the door.
