Abstract
Description
Technical Field
[0001] This application relates to the field of fireproof window technology, and in particular to a fireproof window. Background Technology
[0002] Fireproof windows are window devices with special fire-resistant properties. Traditional windows, on the other hand, not only fail to prevent the spread of fire during a fire, but the glass is also prone to breakage at high temperatures, potentially becoming a channel for the spread of fire.
[0003] However, in actual fire scenarios, due to reasons such as prioritizing evacuation, chaotic scenes, or inaccessibility, it is often difficult to ensure that fireproof windows can be manually closed in a timely manner. In addition, although existing fireproof window products have certain fire resistance and heat insulation properties, due to factors such as structural design, sealing materials, and installation precision, there is still a risk that fire smoke can seep through the gaps in the window frame. This not only affects the safety of evacuation routes but may also accelerate the spread of fire.
[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention
[0005] Based on this, this application provides a fireproof window to solve one of the aforementioned technical problems.
[0006] The technical solution adopted by this application to solve its technical problem includes: a window body, including a window frame and a window sash, wherein fireproof glass is installed on the window sash, the window sash is installed on the window frame via a rotating shaft, and a first gear is fixedly connected to the rotating shaft; a drive device, including a motor and a second gear, wherein the output end of the motor is equipped with the second gear for driving the rotating shaft to open and close the window sash; and a spraying device, including a coil spring, a reciprocating screw, a piston, and a transfer chamber, wherein a fixed shaft is installed at the center of the coil spring, and ratchet wheels are installed at both ends of the coil spring, with the ratchet teeth installed in opposite directions, and the piston is slidably disposed in the transfer chamber for spraying one side of the window sash.
[0007] In some embodiments, the ratchet is an internal ratchet, one end of one ratchet is rotatably disposed at one end of the second gear, and one end of the other ratchet is rotatably connected to a transmission plate.
[0008] In some embodiments, one end of the reciprocating lead screw is mounted on one end of the transmission plate, and the other end of the screw has a protrusion.
[0009] In some embodiments, a sliding bracket is mounted on one end of the piston, and the sliding bracket is threaded onto the reciprocating lead screw.
[0010] In some embodiments, the motor is mounted inside the window frame.
[0011] In some embodiments, the first gear meshes with the second gear.
[0012] In some embodiments, the transfer chamber has an inlet and an outlet, and both the inlet and the outlet are equipped with a one-way valve.
[0013] In some embodiments, the window frame is also equipped with an atomizing nozzle and a smoke sensor, and has a water tank inside.
[0014] In some embodiments, the water inlet is connected to the water tank via a connecting pipe, and the water outlet is connected to the atomizing nozzle via a connecting pipe.
[0015] The beneficial effects of this application are as follows: when the smoke sensor detects a fire, the motor drives the window sash to close while the coil spring stores energy. After the coil spring is released, it drives the piston to draw water and spray it out in atomized form. The liquid fills the gap between the window frame and the window sash, effectively preventing the possibility of smoke seeping in through the gap. Attached Figure Description

[0023] In the embodiments of this application, please refer to Figure 1-4 As shown, this application provides a fireproof window, mainly comprising: a window body 1, including a window frame 11 and a window sash 12, wherein fireproof glass is installed on the window sash 12, and the window sash 12 is installed on the window frame 11 via a rotating shaft 121, wherein a first gear 122 is fixedly connected to the rotating shaft 121; a drive device 2, including a motor 21 and a second gear 22, wherein the output end of the motor 21 is equipped with the second gear 22, for driving the rotating shaft 121 to drive the window sash 12 to open and close; and a spray device 3, including a coil spring 31, a reciprocating screw 32, a piston 33, and a transfer chamber 34, wherein a fixed shaft 311 is installed at the center of the coil spring 31, and ratchet 312 is installed at both ends of the coil spring, with the ratchet teeth installed in opposite directions; and the piston 33 is slidably disposed in the transfer chamber 34 for spraying one side of the window sash 12.
[0024] Specifically, when a fire is detected by the smoke sensor 113, the motor 21 starts to rotate, driving the second gear 22 to close the window sash 12. At the same time, it drives the coil spring 31 to rotate. When the motor 21 reaches the predetermined stroke and stops rotating, the coil spring 31 starts to release and reverse. While reversing, it drives the ratchet 312 below to rotate, which drives the piston 33 to move up and down through the reciprocating screw 32. Water is then pumped out through the transfer chamber 34 and finally sprayed out. The system automatically closes and starts spraying water at the same time.

[0028] Specifically, in order to prevent the piston 33 and the reciprocating lead screw 32 from interfering with each other, a sliding bracket 331 is installed at one end of the piston 33, and the sliding bracket 331 is threaded onto the reciprocating lead screw 32.
[0029] Preferably, the motor 21 is installed inside the window frame 11 to prevent damage to the motor 21 due to external factors.
[0030] Preferably, in order to enable the motor 21 to activate the spray device 3 while closing the fireproof window, the first gear 122 meshes with the second gear 22.
