Description

Technical Field

[0001] The present application relates to the field of fire protection technology, and in particular to an automatic smoke exhaust device. Background Art

[0002] With the acceleration of urbanization and the rapid rise of high-rise buildings, fire safety issues have gradually become prominent and the focus of public attention. In a fire, the rapid spread and accumulation of smoke poses a serious threat to people's lives and property. Therefore, the development and application of efficient automatic smoke exhaust devices for fire engineering has become extremely important.

[0003] At present, the mainstream fire smoke exhaust system on the market mainly relies on an electrically driven fan to remove smoke. For example, the automatic smoke exhaust device for fire engineering with publication number CN217636091 U includes a smoke exhaust pipe, a fixing seat, an electric telescopic rod, a cover plate, a connecting plate, a sealing plate and other components. In an idle state, the electric telescopic rod will shrink, and the cover plate will be driven to move up through the connecting plate, so that the filter screen is collected inside the smoke exhaust pipe. At the same time, the cover plate fits the smoke exhaust pipe, and the sealing plate seals the opening of the smoke exhaust pipe, effectively preventing dust and other impurities from accumulating in the smoke exhaust pipe and causing blockage, thereby ensuring the normal use of the device. However, this design still has obvious shortcomings. The opening method of the cover plate is completely dependent on the electric telescopic rod. When a fire occurs, the power supply may be extremely unstable due to various factors, causing the electric telescopic rod to fail to work properly, thereby affecting the opening of the cover plate and the smoke exhaust effect. Once the electric telescopic rod fails, the entire smoke exhaust system may be paralyzed and unable to effectively remove smoke, increasing the hazard of the fire and the difficulty of rescue.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0025] See also Figure 1 The present application provides an automatic smoke exhaust device, including a smoke exhaust device body 10 and an automatic opening and closing mechanism 20.

[0026] The smoke exhaust device body 10 is used for exhausting smoke, and the automatic opening and closing mechanism 20 is used for automatically opening the smoke exhaust port.

[0027] See also Figure 1 , Figure 2 , Figure 5 The smoke exhaust device body 10 includes a smoke exhaust frame 110 and a mounting plate 120 welded to the outer wall of the smoke exhaust frame 110 and a plurality of mounting holes 130 opened on the side wall of the mounting plate 120. It also includes a support portion 140 welded to the inner wall of the smoke exhaust frame 110 and two air supply members 150 installed on the support portion 140; the support portion 140 includes a support rod 141 and two protruding blocks 142; the air supply member 150 includes a driving motor 151 and a smoke exhaust fan 152.

[0028] The smoke exhaust frame 110 is the core part of the device, responsible for guiding the flow of smoke to ensure its smooth exhaust. Its structure is strong and can withstand the high temperature and high pressure environment of the fire scene to ensure that the smoke exhaust work is not affected.

[0029] Among them, the mounting plate 120 is a component that connects the smoke exhaust device body 10 to a building or other structure. By welding its inner wall to one end of the outer wall of the smoke exhaust frame 110, it not only ensures that the connection between the two is firm and reliable, but also effectively prevents smoke from leaking from the connection, thereby enhancing the sealing of the entire smoke exhaust system; at the same time, it ensures that when a fire occurs, the smoke exhaust device will not be easily vibrated or fall off, thereby ensuring the continuity and stability of the smoke exhaust effect.

[0030] Among them, the equally spaced arrangement of the mounting holes 130 makes the installation process more standardized and normalized, and can ensure that the smoke exhaust device body 10 remains in a horizontal or vertical state during installation, thereby ensuring the optimization of the smoke exhaust effect. At the same time, the equally spaced mounting holes 130 are also convenient for using a variety of different fixings and connection methods, such as bolts, screws, etc., to adapt to different installation environments and requirements; in addition, it is also possible to consider adding reinforcing ribs or boss structures around the mounting holes 130 to improve the bearing capacity and seismic resistance of the mounting plate 120.

[0031] Among them, the specific design of the support part 140 includes a support rod 141 and two protruding blocks 142. The support rod 141 plays the main supporting role, and the two protruding blocks 142 are respectively located at both ends of the side walls of the support rod 141, which is convenient for installing two air supply parts 150. The protruding blocks 142 protrude from the support rod 141 to facilitate the rotation of the smoke exhaust fan 152 without hitting the support rod 141.

[0032] Among them, in order to improve the smoke exhaust efficiency and ensure the rapid exhaust of smoke, two air supply members 150 are specially designed inside the smoke exhaust frame 110. These two air supply members 150 are cleverly installed on the two protruding blocks 142 mentioned above, thereby ensuring their stability and functionality; the drive motor 151 serves as the power source of the air supply member 150, and its fixed end is tightly connected to the inner wall of the protruding block 142 by bolts. This connection method is not only simple and fast, but also can withstand greater force and vibration, ensuring the stability and reliability of the drive motor 151 during operation. The output end of the drive motor 151 passes through the protruding block 142 and is fixedly connected to the smoke exhaust fan 152, thereby realizing power transmission and control of the smoke exhaust fan 152; the function of the smoke exhaust fan 152 is to generate airflow by rotation to quickly exhaust smoke from the smoke exhaust frame 110. By being fixedly connected to the output end of the drive motor 151, the smoke exhaust fan 152 can be quickly started and generate a strong airflow driven by the drive motor 151, thereby effectively exhausting smoke from the fire scene.

[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The automatic opening and closing mechanism 20 includes an automatic gate member 210 and a blocking member 220 installed on the smoke exhaust frame 110; the automatic gate member 210 includes a groove 211, an L-shaped plate 212, a plug hole 213, a T-shaped column 214 and a thermal expansion block 215; the blocking member 220 includes a blocking plate 221, a cross bar 222, two connecting columns 223 and two holes 224.

[0034] Among them, the automatic gate member 210 can make the blocking plate 221 flip over when heated. The shape and size of the groove 211 opened at the top of the blocking plate 221 are precisely calculated to ensure that it can be tightly clamped with one end of the L-shaped plate 212. This clamping design is not only simple and effective, but also can ensure the stability and firmness of the L-shaped plate 212 in the groove 211; one end of the L-shaped plate 212 is clamped with the inside of the groove 211, and a plug hole 213 is opened on the surface of the other end. The design of the plug hole 213 allows the T-shaped column 214 to be smoothly inserted into it and fits tightly with the inner wall of the plug hole 213. The bottom end is welded to the surface of the smoke exhaust frame 110. This welding The connection method is not only firm and reliable, but also able to withstand greater forces and vibrations. The presence of the T-shaped column 214 enables the L-shaped plate 212 to be firmly fixed on the smoke exhaust frame 110, thereby achieving the overall stability and functionality of the automatic card door component 210; the thermal expansion block 215 is one of the key components of the automatic card door component 210, which utilizes the thermal expansion characteristics of the material to achieve the function of releasing the blocking plate 221. The two ends of the thermal expansion block 215 are respectively glued to the opposite ends of the smoke exhaust frame 110 and the L-shaped plate 212 using nano glue. This gluing method is simple and effective, and can ensure a tight connection between the thermal expansion block 215 and the smoke exhaust frame 110 and the L-shaped plate 212.

[0035] The design of the blocking piece 220 can block the smoke outlet of the smoke exhaust frame 110. The groove 211 at the top of the blocking plate 221 is engaged with the L-shaped plate 212, thereby ensuring that the smoke exhaust frame 110 can be completely sealed when it needs to be closed. At the same time, the inner bottom of the blocking plate 221 is welded to the side wall of the cross bar 222. This connection method is both firm and stable, enabling it to withstand greater forces and vibrations. The cross bar 222 serves as a supporting component for the blocking plate 221, and has two connecting columns 223 at both ends. These two connecting columns The design of the column 223 enables the cross bar 222 to be hinged to the holes 224 on both sides of the inner wall of the smoke exhaust frame 110. This hinged design allows the sealing piece 220 to flip smoothly when it needs to be opened, thereby avoiding impact and damage to the smoke exhaust frame 110; the position and size of the hole 224 are precisely calculated to ensure a tight hinge with the outer wall of the connecting column 223. This hinged design not only allows the sealing piece 220 to be flexibly opened and closed, but also ensures its sealing in the closed state.

[0036] The working principle of the automatic smoke exhaust device is as follows: when a fire occurs, the temperature in the air rises to the threshold of the thermal expansion block 215, causing it to expand and deform, thereby causing the L-shaped plate 212 to move upward along the T-shaped column 214. At the same time, the L-shaped plate 212 disengages from the inside of the groove 211, and the restriction on the top of the blocking plate 221 is released, and then the plate is flipped along the cross bar 222 at the hinge with the smoke exhaust frame 110, exposing the smoke exhaust port of the smoke exhaust frame 110. At this time, the drive motor 151 installed on the two raised blocks 142 drives the smoke exhaust fan 152 to rotate to quickly exhaust the smoke from the smoke exhaust frame 110.

[0037] It should be noted that the specific model specifications of the drive motor 151 and the thermal expansion block 215 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] The power supply and principle of the driving motor 151 are clear to those skilled in the art and will not be described in detail here.

[0039] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
