Description

Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, in particular to an embedded fireproof rolling shutter. Background Art

[0002] At present, a fireproof curtain is a facility for fireproof isolation, usually installed in areas such as channels, corridors, doors and windows of buildings, and can play a role in blocking the spread of fire during a fire. However, in the scenic area of cultural relic buildings, existing installation methods such as demolishing old buildings and adding firewalls between buildings will greatly reduce the beauty of cultural relic buildings and the scenic area.

[0003] To solve the above problems, the prior art patent (CN211201633U) discloses an embedded fireproof rolling shutter. The embedded box body can greatly save the occupied space. When a fire breaks out, the rolling shutter uses power-assisted rising to form a flame-retardant partition, greatly improving the safety performance. At the same time, it is more beautiful when installed between cultural relic buildings. The water-cooling tank can ensure that the fireproof rolling shutter has a cooling effect. At the same time, when the fire is large, the water in the water-cooling tank can be sprayed out through the pressure film to further play a role in blocking and extinguishing the fire.

[0004] However, in the above prior art, when the embedded fireproof rolling shutter is wound up, the fireproof rolling shutter may be damaged due to lack of restriction. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an embedded fireproof rolling shutter, which solves the technical problem that the fireproof rolling shutter may be damaged due to lack of restriction when the embedded fireproof rolling shutter is wound up in the prior art.

[0023] For this specific embodiment, the placement plate 102 is fixedly connected to the embedded box 101 and is located inside the embedded box 101. The guide rail 103 is fixedly connected to the embedded box 101 and is located below the embedded box 101.

The fixing plate 113 fixes the position of the solenoid valve 114. The water inlet pipe 115 is communicated with an external water supply device. By controlling the solenoid valve 114, it can be controlled whether the water flow in the water inlet pipe 115 flows into the connecting pipe 116.

[0026] Meanwhile, the connecting pipe 116 is detachably connected to the output end of the solenoid valve 114 and penetrates through one side of the embedded box 101.

The guide rail 103 is fixedly connected to the embedded box 101 and is located below the embedded box 101.

At the same time, the rotation of the winding roller 105 can also drive the first rotating rod 107 to rotate. The first rotating rod 107 drives the first gear 108 to rotate. The first gear 108 drives the second rotating rod 109 to rotate through the second gear 110. The second rotating rod 109 drives the limiting roller 111 to rotate, and the rotation direction of the limiting roller 111 is opposite to that of the winding roller 105, thereby limiting the rolling curtain body 112. The water inlet pipe 115 is communicated with an external water supply device. Controlling the solenoid valve 114 allows the water in the water inlet pipe 115 to flow into the connecting pipe 116. The connecting pipe 116 conveys the inflowing water into the water distribution block 117 and sprays it through the spray head 118, achieving the effect of cooling the rolling curtain body 112, thus solving the problem that the fireproof rolling curtain may be damaged due to lack of limitation during winding.

[0028] The second embodiment of the present application is as follows:

[0029] Based on the first embodiment, please refer to Figure 5 , Figure 5 which is a schematic structural diagram of the second embodiment of the present utility model.

[0030] The present utility model provides an embedded fireproof rolling shutter, which further includes a hinge 201, a protective shell 202 and a handle 203. The above-mentioned solution solves the problem in the prior art that the solenoid valve 114 lacks protection measures, resulting in easy damage to the heat dissipation components.

[0031] Among them, the hinge 201 is fixedly connected to the embedded box 101 and is located above the embedded box 101. The protective shell 202 is detachably connected to the hinge 201 and is located on one side of the hinge 201. The protective shell wraps the water inlet pipe 115, the solenoid valve 114 and the connecting pipe 116. The handle 203 is fixedly connected to the protective shell 202 and is located above the protective shell 202. The hinge 201 connects the protective shell 202 to the embedded box 101. Holding the handle 203 can open the protective shell 202 to maintain the components inside.

[0032] When using the embedded fireproof rolling shutter of this embodiment, by setting the hinge 201, the protective shell 202 and the handle 203, the hinge 201 connects the protective shell 202 to the embedded box 101 and increases the degree of freedom of the protective shell 202. The protective shell 202 can protect the water inlet pipe 115, the solenoid valve 114 and the connecting pipe 116. Holding the handle 203 can open the protective shell 202 to maintain the components inside, thereby solving the problem that the solenoid valve 114 lacks protection measures, resulting in easy damage to the heat dissipation components.
