Description

Technical Field

[0001] This invention relates to the field of construction, and more specifically to a building safety system. Background Technology

[0002] Against the backdrop of rapid urban development, more and more cities are facing problems such as scarce land resources and rising land costs that constrain urban industrial development. This has led to the emergence of high-rise, multi-level, large-space factory buildings. Unlike traditional factories, this new type of industrial building not only possesses the spatial characteristics of both large-space factories and high-rise buildings, but also typically has high requirements for safety and indoor ventilation within its facilities. In recent years, with the development of environmentally friendly and energy-saving double-glazed curtain walls, their structural form is conducive to energy conservation and has great application potential in high-rise, multi-level, large-space factory buildings. Furthermore, with the development of information technology and the leap in sensor technology, intelligent ventilation optimization control is beginning to gain public attention. For high-rise, multi-level, large-space factory buildings, this optimization can maximize indoor thermal comfort while reducing energy consumption.

[0003] In practical engineering work, the following problems exist:

[0004] I. Existing factory buildings generally have a central ventilation system at the top. However, the top ventilation structure, such as ventilation grilles and filters, requires cleaning and is not easy to clean.

[0005] Second, existing factory buildings have fire sprinkler safety protection measures, which are achieved by melting the hot melt element when the temperature rises, thereby driving the mechanism to spray; however, factory spaces are large and do not heat up as quickly as private rooms; there are issues such as slow sensing feedback and spray delay.

[0006] Third, existing fire safety sprinkler devices, such as CN105736783A, have hot-melt gaskets that, although they have a hot-melt function, have poor fixing performance and cannot provide sufficient long-term stability.

[0007] Fourth, in existing fire safety sprinkler systems, such as CN105736783A and CN105498145A, it is undesirable for parts to fall or break due to temperature changes under similar conditions.

[0008] Fifth, in the existing fire safety sprinkler system, the main valve needs to be shut off to control the water supply after the danger has passed, and then the sprinkler module can be replaced or maintained. However, the main valve controls the water supply over a large area, which can lead to a sudden water outage over a large area, causing inconvenience to production and daily life. Summary of the Invention

[0009] To overcome the above problems, the present invention proposes a solution that addresses multiple problems simultaneously.

[0010] The technical solution adopted by the present invention to solve its technical problem is: a building safety system, including a lower span beam, an upper span beam, a column, a main beam, a water inlet pipe, an upper water outlet pipe, a lower water outlet pipe, and a valve; wherein the valve includes a driving component, a valve plug, a water inlet hole, a central cavity, an upper water outlet hole, a lower water outlet hole, a valve body, a driving shaft, an inlet, an upper outlet, a lower outlet, a vertical hole, a channel, a thermoplastic element, and a blocking component;

[0011] The column supports a main beam, and the main beam is connected to a lower span beam and an upper span beam, which are arranged parallel to each other. The upper span beam is equipped with a cold air duct, and the cold air in the cold air duct is delivered into the building through the upper span beam. The valve is installed in the lower span beam, which includes an upper wall and a lower wall.

[0012] The valve is equipped with an inlet pipe, an upper outlet pipe, and a lower outlet pipe. The drive component is located above the upper wall, and a drive shaft is connected below the drive component. The drive shaft passes through the upper wall and extends into the lower span beam. The lower end of the drive shaft is connected to the valve plug. The valve body is located inside the lower span beam. The drive component can drive the valve plug to rotate via the drive shaft. The valve plug is equipped with an inlet hole, a middle cavity, an upper outlet hole, a lower outlet hole, and a channel. The valve body is equipped with an inlet, an upper outlet, a lower outlet, and a vertical hole. The lower outlet hole is fitted with the blocking component, and the channel is located below the lower outlet hole. A heat fusion element is installed in the channel. The heat fusion element includes an upper heat fusion part and a lower heat fusion part, and the heat fusion element supports the blocking component. The lower part of the valve body is equipped with a vertical hole, which communicates with an opening on the lower wall.

[0013] In the top-flow state, the valve plug rotates so that water sequentially passes through the inlet pipe, inlet, inlet hole, middle cavity, upper outlet hole, upper outlet, and upper outlet pipe; in the standby state, the valve plug rotates so that the lower outlet hole is aligned with the lower outlet, the channel covers the vertical hole, the lower surface area of ​​the lower hot-melt part is larger than the cross-sectional area of ​​the vertical hole, and the area of ​​the opening is larger than the cross-sectional area of ​​the vertical hole; when the temperature rises and the hot-melt element melts, the blocking element falls through the channel and the vertical hole and is intercepted by the mesh set in the opening; in the fully closed state, the middle cavity is not connected to the inlet.

[0014] Preferably, the water inlet extends circumferentially along the valve plug.

[0015] Preferably, a pipe support is provided in the lower span beam.

[0016] Preferably, the area of ​​the lower surface of the upper hot-melt part is smaller than the area of ​​the upper surface of the lower hot-melt part.

[0017] Preferably, the channel includes a first section and a second section, the first section accommodating the upper hot-melt part and the second section accommodating the lower hot-melt part.

[0018] Preferably, in standby mode, the upper water outlet is not aligned with the upper outlet.

[0019] Preferably, in standby mode, the blocking component isolates the middle cavity from the lower outlet.

[0020] Preferably, in the upward water flow state, the lower water outlet and the lower outlet are not aligned.

[0021] Preferably, the upper water outlet pipe is connected to the upper pipe, and a nozzle is provided above the upper pipe extending through the upper wall.

[0022] Preferably, the lower water outlet pipe is connected to the lower pipe, and a nozzle is provided below the lower pipe extending through the lower wall.

[0023] The beneficial effects of this invention are:

[0024] I. Regarding the first point raised in the background technology, the span beams in the building are set as upper span beams and lower span beams. Both upper and lower span beams are hollow and set parallel and adjacent to each other. The upper span beam is equipped with a cooling and ventilation path, and the lower span beam is equipped with a water supply path. The ventilation module in the upper span beam discharges air downwards, and the discharged air can be blocked and dispersed by the lower span beam. Thus, the lower span beam acts as an air conditioning deflector to prevent cold air from blowing directly downwards. The water supply pipe in the lower span beam is equipped with upward spraying modules and downward spraying modules. The upward spraying modules can clean the grilles and filters of the ventilation modules, and the downward spraying modules can serve as fire sprinklers.

[0025] Second, regarding the second point raised in the background technology, two water outlet pipes are installed in the lower span beam. The upper water outlet pipe is connected to an upward-facing spray nozzle, and the lower water outlet pipe is connected to a downward-facing spray nozzle. The flow of the two water outlet pipes is switched or both are closed by a valve. When the danger in the plant is low and the temperature does not rise rapidly, the upper water outlet pipe can be connected manually or through the controller to spray water from the upper water outlet pipe (at this time, the fan blades of the ventilation module can be closed to block more water downwards). When the danger in the plant is high and the staff does not have time or it is unnecessary to risk operating the valve, the thermoplastic element in the valve melts after the plant temperature rises rapidly, causing the lower water outlet pipe to connect for automatic spraying. Thus, both manual rapid spraying and automatic spraying can be achieved.

[0026] Alternatively, if the fire cannot be effectively controlled even after the thermal fusion element has melted, a targeted sprinkler water volume control system needs to be activated. This involves using temperature monitoring elements combined with indoor wind speed and direction monitoring elements to obtain the indoor thermal environment distribution during a fire, and then using CFD simulation to predict the fire's development. Based on the fire situation in different areas of the room, the water output of the dotted automatic sprinkler outlets is controlled. Targeted, excessive spraying is applied to the ignition point and areas with extremely high temperatures, targeted spraying is applied to areas along the direction of fire development, and preventative spraying is applied to high-risk areas downwind.

[0027] Thirdly, regarding the third point raised in the background technology, the hot-melt element is fixed to the lower part of the valve plug and is configured to include an upper part and a lower part. The size of the lower part is larger than the size of the hot air passage on the valve body, so that it will not fall off and is easy to support. The upper part of the hot-melt element supports the blocking component, thus providing better stability. The opening area of ​​the lower wall of the lower beam is larger than the area of ​​the hot air passage on the valve body, thus facilitating more sufficient contact of hot air.

[0028] Fourthly, in response to the fourth point raised in the background technology, an opening is provided on the lower wall of the lower span beam, and a blocking part is provided inside the opening. The blocking part is mesh-like, so that after the hot melt element melts, it can fall through the valve body and the opening, while the solid blocking element will be blocked by the mesh and will not fall, which makes it easier to maintain the integrity of the blocking element for recycling.

[0029] Fifthly, regarding the fifth point raised in the background technology, the valve not only controls the flow switching between the upper and lower water outlet pipes, but also has a fully closed position. When the crisis is resolved, the valve can be switched to the fully closed position to cut off the water supply. The main valve can be closed for maintenance at night or other reasonable time periods when preparations are made, without the need to immediately or temporarily close the main valve to avoid production and living losses.
