Description

Technical Field

[0001] This application relates to the field of ventilation equipment technology, and in particular to a fireproof partition ventilation window. Background Technology

[0002] In many buildings, equipment, and other installations, ventilation openings and corresponding ventilation windows are typically installed to facilitate air circulation and heat dissipation. However, in emergencies such as fires, these ventilation openings often become channels for the spread of fire and smoke, accelerating the spread of the fire, greatly hindering personnel evacuation and firefighting and rescue operations, and increasing the losses caused by the fire.

[0003] Currently, most ventilation windows on the market only have basic ventilation functions and lack effective fire-resistant isolation measures. Although some ventilation windows use fire-resistant materials, these materials may not be able to effectively prevent the spread of fire and smoke in a timely manner under high-temperature environments, failing to meet the fire protection requirements in actual use. Therefore, developing a fire-resistant, fire-resistant ventilation window that can automatically seal ventilation openings under high-temperature environments such as fires is of significant practical importance. Utility Model Content

[0004] In order to effectively prevent the spread of fire and smoke through ventilation openings, ensure the safety of the target device, and further reduce fire losses, this application provides a fireproof partition ventilation window.

[0005] The fire-resistant partition ventilation window provided in this application adopts the following technical solution: A fireproof partition ventilation window includes a ventilation opening disposed on a target device, a ventilation cover covering the ventilation opening, the ventilation cover having a plurality of ventilation holes, and a fire-retardant expanding coating coated thereon, the fire-retardant expanding coating expanding to seal the ventilation holes after the temperature reaches a preset value.

[0006] By adopting the above technical solution, a ventilation hood with ventilation holes is installed on the ventilation opening of the target device and coated with fire-retardant expanding paint, combining ventilation and fireproof isolation functions. Under normal conditions, the ventilation holes ensure air circulation; when a fire occurs and the temperature reaches a preset value, the fire-retardant expanding paint expands and seals the ventilation holes, effectively preventing the spread of fire and smoke through the ventilation openings, ensuring the safety of the target device and reducing fire losses.

[0007] Optionally, the fire-retardant intumescent coating is applied to the inner walls of the ventilation hood and the ventilation openings.

[0008] By employing the above-mentioned technical solution, fire-retardant intumescent coating is applied to the inner walls of ventilation hoods and vents. This coating method offers significant advantages. Firstly, it comprehensively covers the surface of the ventilation hood and the inner walls of the vents, ensuring that the coating can respond simultaneously from all directions when the temperature rises, expanding rapidly and uniformly to form a denser and more effective sealing layer, greatly improving the reliability of fire-resistant partitions.

[0009] Optionally, the ventilation hood is a honeycomb panel.

[0010] Optionally, the ventilation hood is a porous fire-resistant board or a grid-type fire-resistant board.

[0011] Optionally, a support frame is fixedly connected to the vent, and the honeycomb panel is fixedly connected to the support frame.

[0012] By adopting the above technical solution, a support frame is fixedly connected to the ventilation opening, and the honeycomb panel is fixedly connected to the support frame, significant technical benefits are achieved. The support frame provides a stable support structure for the honeycomb panel ventilation hood, enhancing the overall strength and stability of the ventilation window, enabling it to withstand greater external forces and vibrations. This helps improve the fire-resistant isolation effect of the ventilation hood in the event of a fire, reducing the spread of fire and smoke.

[0013] Optionally, the ventilation hood can be detachably installed and placed over the ventilation opening.

[0014] By adopting the above technical solution, the ventilation hood can be detached and installed over the ventilation opening, which brings many conveniences and technical advantages. In daily use, it is convenient to clean and maintain the ventilation window. The ventilation hood can be disassembled regularly to clean the dust and debris in the ventilation holes, ensuring ventilation effect. When the ventilation hood is damaged, aged, or the performance of the fire-resistant coating deteriorates due to long-term use, it can be easily replaced without large-scale modification of the entire ventilation window, reducing maintenance costs and time costs.

[0015] Optionally, the ventilation hood is connected to the ventilation opening via a threaded connection.

[0016] By adopting the above technical solution, the ventilation hood is connected to the ventilation opening through threaded parts. This connection method has the technical advantages of being easy to operate and reliable in connection.

[0017] Optionally, a pressure plate is provided on the side of the ventilation hood away from the ventilation opening, and the pressure plate is connected to the ventilation opening by a threaded component.

[0018] By adopting the above technical solution, a pressure plate is set on the side of the ventilation hood away from the ventilation opening, and the pressure plate is connected to the ventilation opening by threaded parts, which further enhances the installation firmness and fireproof isolation performance of the ventilation hood.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. By applying fire-retardant expanding coating to the ventilation hood, the coating undergoes a chemical reaction and expands in volume under the high temperature during a fire, sealing the ventilation holes on the hood. This effectively prevents the spread of fire and smoke through the ventilation openings, ensuring the safety of the target device and further reducing fire losses. 2. The support frame provides a stable support structure for the honeycomb panel ventilation hood, which helps to improve the fireproof isolation effect of the ventilation hood in the event of a fire.

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. Example 1

[0028] This application discloses a fireproof, partition-type ventilation window. For example... Figure 1-2 The fire-resistant partition ventilation window includes a ventilation window 1 installed on the target device. The ventilation window 1 has a ventilation opening 11 for ventilating the interior of the target device, which can be an energy storage container, a power distribution cabinet, or other cabinet with an explosion hazard. The ventilation window 1 is equipped with a ventilation hood 12 that covers the ventilation opening 11. The ventilation hood 12 has ventilation holes 13 to allow ventilation while reducing the entry of foreign objects into the target device.

[0029] The ventilation hood 12 is coated with a fire-retardant expanding coating, which covers both the inner and outer sides of the ventilation hood 12 and the inner wall of the ventilation opening 13. When a fire occurs inside the target device, the temperature rises, causing the fire-retardant expanding coating to undergo a chemical reaction and expand in volume, thereby sealing the ventilation opening 13 and achieving the fireproofing and isolation effect on the ventilation opening 11.

[0030] In this embodiment, the ventilation hood 12 is a honeycomb panel, and the honeycomb holes on the honeycomb panel are ventilation holes 13. The front and back sides of the honeycomb panel with fire-retardant expansion coating, as well as the inner wall of the honeycomb holes, are covered with the coating.

[0031] The ventilation hood 12 is detachably installed on the ventilation window 1, facilitating the operator's installation, removal, and maintenance of the ventilation hood 12. A pressure plate 14 is provided on the side of the ventilation hood 12 away from the ventilation window 1. A threaded component 15 is provided on the pressure plate 14. The threaded component 15 can be a stud, bolt, or nut, etc. In this embodiment, the threaded component 15 is a stud fixedly connected to the ventilation window 1. The stud passes through the pressure plate 14 and the honeycomb plate, and a nut is threaded onto it. By tightening the nut, the operator presses the honeycomb plate onto the ventilation window 1, thereby achieving detachable and fixed installation of the ventilation hood 12 on the ventilation window 1. Example 2

[0032] like Figure 3-4 The difference between this embodiment and Embodiment 1 is that, in order to improve the structural stability of the honeycomb panel under high-temperature flame isolation conditions, a support frame 16 is fixed at the ventilation opening 11 of the ventilation window 1. The support frame 16 is used to support the honeycomb panel, reducing the problem of the honeycomb panel bending and deforming under the pressure difference inside and outside the target device, which affects the fireproof isolation effect. Example 3

[0033] like Figure 5-6 The difference between this embodiment and Embodiment 1 is that the ventilation hood 12 can be configured as a porous fire-resistant board or a grid-type fire-resistant board to improve the structural stability of the ventilation hood 12. In this embodiment, the ventilation hood 12 is a grid-type fire-resistant board. This reduces the deformation and bending of the ventilation hood 12 when it is heated and the ventilation opening 11 is sealed, thus reducing its fire-resistant isolation effect in a fire.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
