Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a ventilation device for building construction. Background Technology

[0002] Building construction refers to the construction of a building, which can also be described as the process of turning the various lines on the design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc.

[0003] Existing ventilation systems used in building construction employ a single ventilation duct with a fan inside to draw smoke and dust away during a fire. However, this type of system is susceptible to problems if a power outage occurs during a fire, as the smoke cannot be expelled and can be inhaled into the lungs, leading to poisoning. Utility Model Content

[0004] The purpose of this utility model is to provide a ventilation device for building construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation device for building construction, comprising a ventilation pipe, a positioning plate fixedly connected inside the ventilation pipe, a positioning ventilation opening on the top of the positioning plate, a heat-sensitive plate above the positioning plate, a positioning ring fixedly connected to the top of the heat-sensitive plate, the positioning ring being fixedly connected inside the ventilation pipe, and a staggered ventilation opening on the top of the heat-sensitive plate, wherein the positioning ventilation opening and the staggered ventilation opening are arranged in an alternating manner.

[0006] Preferably, a sliding rod is fixedly connected to the bottom of the thermal plate, the sliding rod is slidably connected inside the positioning plate, and a limit plate is fixedly connected to the end of the sliding rod away from the thermal plate.

[0007] Preferably, a spring is sleeved on the outside of the sliding rod, and the spring is fixedly connected between the positioning plate and the limiting plate. A rainproof component is provided above the ventilation pipe.

[0008] Preferably, the rainproof component includes a rotating tube, which is rotatably connected to the top of a ventilation tube, and a ventilation ball is fixedly connected to the top of the rotating tube, the ventilation ball being spherically shaped.

[0009] Preferably, the ventilation ball has an exhaust port on its exterior, and there are multiple sets of exhaust ports arranged in a circular array on the exterior of the ventilation ball. An installation component is provided below the ventilation ball.

[0010] Preferably, the mounting assembly includes a mounting plate, which is fixedly connected to the outside of the ventilation duct at a position away from the rotating duct. The top of the mounting plate has mounting holes, and there are four sets of mounting holes arranged in a rectangular array.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: heat will cause the heat-sensitive plate to warp, thus creating a gap between the positioning plate and the heat-sensitive plate, allowing smoke to be discharged from the positioning vent and the staggered vent, achieving the effect of ventilation and smoke extraction. This solves the problem of using a single ventilation duct with a fan structure inside to suck smoke away from the ventilation duct, but in the event of a fire, if a power failure occurs, the smoke cannot be discharged, leading to smoke inhalation into the lungs and poisoning. This invention improves the stability of smoke extraction. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a technical solution: such as Figures 1-4The ventilation device shown includes a ventilation pipe 1, a positioning plate 2 fixedly connected inside the ventilation pipe 1, a positioning ventilation port 5 opened at the top of the positioning plate 2, a heat-sensitive plate 3 arranged above the positioning plate 2, a positioning ring 4 fixedly connected at the top of the heat-sensitive plate 3, the positioning ring 4 fixedly connected inside the ventilation pipe 1, an offset ventilation port 6 opened at the top of the heat-sensitive plate 3, the positioning ventilation port 5 and the offset ventilation port 6 are arranged in an alternating manner, a sliding rod 7 fixedly connected at the bottom of the heat-sensitive plate 3, the sliding rod 7 is slidably connected inside the positioning plate 2, and a limit plate 8 is fixedly connected to the end of the sliding rod 7 away from the heat-sensitive plate 3.

[0019] During operation, in the event of a fire, hot air and smoke rise. At this time, the heat-sensitive plate 3 inside the ventilation duct 1 deforms due to the heat and tilts up. When the heat-sensitive plate 3 tilts up, its position is limited by the positioning ring 4, which allows the positioning plate 2 to separate from the heat-sensitive plate 3. This allows the hot air and smoke to be discharged from the staggered positioning ventilation openings 5 ​​and the misaligned ventilation openings 6. When the heat-sensitive plate 3 tilts up, the sliding rod 7 slides inside the positioning plate 2 to ensure that the heat-sensitive plate 3 does not shift. The limiting plate 8 can also prevent the sliding rod 7 from detaching from the positioning plate 2. This achieves the effect of ventilation and smoke extraction, solving the problem of using a single ventilation duct with a fan structure inside the duct to suck smoke away from the ventilation duct. However, in the event of a fire, if there is a power outage, the smoke cannot be discharged, leading to smoke inhalation into the lungs and poisoning. This improves the stability of smoke extraction.

[0020] Please see Figure 1 , Figure 2 and Figure 3 In the figure, a spring 9 is sleeved on the outside of the sliding rod 7. The spring 9 is fixedly connected between the positioning plate 2 and the limiting plate 8. A rainproof component is provided above the ventilation pipe 1. The rainproof component includes a rotating pipe 12, which is rotatably connected to the top of the ventilation pipe 1. A ventilation ball 10 is fixedly connected to the top of the rotating pipe 12. The ventilation ball 10 is spherically shaped.

[0021] During operation, the limiting plate 8 ensures that the heat-sensitive plate 3 and the positioning plate 2 are in contact, thus preventing air exchange between indoors and outdoors. During normal use, the ventilation ball 10 prevents rainwater from falling into the ventilation pipe 1 and causing water accumulation. The rotating pipe 12 makes it easier to install the ventilation ball 10 above the ventilation pipe 1, achieving the effects of rain protection and wind protection. This solves the problem that rainwater would seep into the room from the positioning ventilation port 5 and the misaligned ventilation port 6 when the pipe is exposed to rain, thus preventing rainwater from entering the room and improving the stability during use.

[0022] Please see Figure 1 and Figure 2As shown in the figure, the ventilation ball 10 has an exhaust port 11 on its outside. There are multiple sets of exhaust ports 11 arranged in a circular array on the outside of the ventilation ball 10. An installation component is provided below the ventilation ball 10. The installation component includes an installation plate 13. The installation plate 13 is fixedly connected to the outside of the ventilation pipe 1 at a position away from the rotating pipe 12. The top of the installation plate 13 has an installation hole 14. There are four sets of installation holes 14 arranged in a rectangular array.

[0023] When in operation, the rising hot air will cause the ventilation ball 10 and the rotating pipe 12 to rotate at the top of the ventilation pipe 1, so that the smoke can be discharged along the exhaust port 11. When the ventilation pipe 1 is installed on the roof, it can be firmly fixed by the mounting plate 13 and the mounting hole 14, achieving a stable installation effect, solving the problem of loosening caused by a single ventilation pipe 1 structure, and improving the stability of the ventilation pipe 1 installation.

[0024] Working Principle: In the event of a fire, hot air and smoke rise. The heat-sensitive plate 3 inside ventilation duct 1 deforms due to the heat, causing it to tilt upwards. As the heat-sensitive plate 3 tilts, it is positioned by the positioning ring 4, creating a gap between the positioning plate 2 and the heat-sensitive plate 3. This allows hot air and smoke to escape through the staggered positioning vents 5 and misaligned vents 6. While the heat-sensitive plate 3 tilts, the sliding rod 7 slides inside the positioning plate 2, ensuring that the heat-sensitive plate 3 does not shift. The limiting plate 8 also prevents the sliding rod 7 from detaching from the positioning plate 2, achieving effective ventilation and smoke extraction. This solves the problem of using a single ventilation duct with an internal fan structure to draw smoke away, which can lead to smoke inhalation and poisoning if power is lost during a fire. The limiting plate 8 improves the stability of smoke extraction, ensuring a smooth flow. The heat-sensitive plate 3 is attached to the positioning plate 2 to prevent indoor and outdoor air from interacting. During normal use, the ventilation ball 10 can prevent rainwater from falling into the ventilation pipe 1 and causing water accumulation. The rotating pipe 12 makes it easier to install the ventilation ball 10 above the ventilation pipe 1, achieving the effect of rain protection and wind protection. This solves the problem that rainwater will seep into the room from the positioning ventilation port 5 and the staggered ventilation port 6 when the pipe is exposed to rain. It prevents rainwater from entering the room and improves the stability during use. When hot air rises, the airflow will drive the ventilation ball 10 and the rotating pipe 12 to rotate on the top of the ventilation pipe 1, so that the smoke can be discharged along the exhaust port 11. When the ventilation pipe 1 is installed on the roof, it can be firmly fixed by the mounting plate 13 and the mounting hole 14, achieving a stable installation effect. This solves the problem that the single ventilation pipe 1 structure will loosen and improves the installation stability of the ventilation pipe 1.
