Description

Technical Field

[0001] This utility model relates to the field of automatic control of smoke exhaust windows, and in particular to a parallel smoke exhaust window pneumatic temperature control release system. Background Technology

[0002] Pneumatic smoke exhaust window systems typically use compressed air as a power source. Triggered by a fire alarm control signal, a pneumatic window opener opens the pneumatic smoke exhaust window, thus achieving natural smoke and heat exhaust. Compared to electric smoke exhaust window systems, this system offers advantages such as wider applicability, less environmental impact, longer service life, greater thrust, faster operation, and lower maintenance costs, making it the preferred natural smoke exhaust system for extremely cold, hot, and humid environments.

[0003] In the existing technology, when a fire occurs, the linkage control box can only receive linkage signals from outside the system, and then trigger each group of pressure gas cylinders to release compressed air to their respective smoke exhaust window mechanisms, thereby opening the pneumatic smoke exhaust windows of each group in the area.

[0004] If extreme situations occur, such as the power, gas, or signal source being cut off from outside the system, the linkage control box will not be able to trigger each group of pressure gas cylinders to open all the pneumatic smoke exhaust windows in the area. Instead, it will have to rely on the pneumatic temperature control release device configured on each smoke exhaust window to open the pneumatic smoke exhaust windows where the smoke temperature at the location of the pneumatic temperature control release device has reached the preset temperature one by one.

[0005] In existing technologies, because it takes time for high-temperature smoke to spread during a fire, pneumatic temperature control release devices and pneumatic smoke exhaust windows closer to the fire source react quickly, while those farther away react slowly. Furthermore, in existing technologies, when a pneumatic temperature control release device detects high-temperature smoke, it only opens its corresponding pneumatic smoke exhaust window, failing to quickly trigger the opening of adjacent pneumatic smoke exhaust windows or all pneumatic smoke exhaust windows in the entire area. Therefore, the actual smoke extraction speed and volume are inferior to solutions where a unified control box opens all pneumatic smoke exhaust windows in the area without power, gas, or signal interruption. Thus, improvements are needed.

[0006] Therefore, there should be a system to respond to sudden fires and to be able to respond to power outages. loss of air In the extreme case of signal failure, quickly open all pneumatic smoke exhaust windows throughout the entire area. method System solutions. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The problem this utility model aims to solve is to provide a parallel pneumatic temperature control release system solution for smoke exhaust windows, so as to overcome the defects in the prior art where the detection time and response time of each pneumatic temperature control release device at different distances from the fire source are inconsistent, and the defect that each pneumatic temperature control release device can only open the corresponding pneumatic smoke exhaust window, and cannot open adjacent pneumatic smoke exhaust windows or all pneumatic smoke exhaust windows in the entire area.

[0009] (II) Technical Solution

[0010] To solve the aforementioned technical problem, this utility model provides a parallel smoke exhaust window pneumatic temperature control release system, comprising:

[0011] Linkage control box;

[0012] A pressure gas cylinder, one end of which is connected to the first pipeline, and the pressure gas cylinder is connected to the linkage control box;

[0013] The smoke exhaust window mechanism includes multiple pneumatic temperature control release devices connected in parallel and a second pipe. Each pneumatic temperature control release device is connected in parallel to the first pipe, and each pneumatic temperature control release device controls one pneumatic smoke exhaust window. Each pneumatic temperature control release device is connected in parallel to the second pipe through a connection point, and the other end of the second pipe is connected to the linkage control box.

[0014] As described above, in the parallel smoke exhaust window pneumatic temperature control release system, optionally, a plurality of first control valves are provided on the second pipe, and the first control valves are located between two adjacent connection points.

[0015] As described above, in the parallel smoke exhaust window pneumatic temperature control release system, optionally, a second control valve is provided on the second pipe, and the second control valve is also located between two adjacent connection points.

[0016] As described above, in the parallel smoke exhaust window pneumatic temperature control release system, optionally, there are multiple pressure cylinders, and each pressure cylinder is connected to the linkage control box.

[0017] As described above, in the parallel smoke exhaust window pneumatic temperature control release system, optionally, the smoke exhaust window mechanism has multiple components, and each smoke exhaust window mechanism is connected to the pressure gas cylinder one by one through the first pipe.

[0018] As described above, in the parallel smoke exhaust window pneumatic temperature control release system, optionally, the linkage control box is connected to an AC220V AC input power supply.

[0019] (III) Beneficial Effects

[0020] This utility model provides a parallel pneumatic temperature control release system for smoke exhaust windows. A linkage control box controls several pressure gas cylinders, each connected to several pneumatic temperature control release devices arranged in parallel. Each pneumatic temperature control release device controls one pneumatic smoke exhaust window. When a fire occurs, the pneumatic temperature control release device that detects the high temperature of the fire smoke sends a signal to the linkage control box. The linkage control box then controls all pressure gas cylinders in the area where the fire occurred, opening all pneumatic smoke exhaust windows controlled by the pressure gas cylinders within the fire area. This invention solves the shortcomings of existing technologies where pneumatic temperature control release devices and pneumatic smoke exhaust windows that are closer to the fire source react quickly, while those that are farther from the fire source react slowly. It also overcomes the limitation that a pneumatic temperature control release device can only open its own corresponding pneumatic smoke exhaust window and cannot quickly trigger the opening of adjacent pneumatic smoke exhaust windows or all pneumatic smoke exhaust windows in the entire area. This allows each pneumatic temperature control release device installed in a local area and connected in parallel to the network to not only open the pneumatic smoke exhaust window it controls, but also trigger the opening of all pneumatic smoke exhaust windows in the entire area, even in extreme cases of power outage, gas outage, and signal interruption. Based on the existing technical solution where the linkage control box can only open all pneumatic smoke exhaust windows in the area after receiving a fire linkage signal from the outside, this technical solution connects the various pneumatic temperature control release devices in parallel into a network. This is equivalent to adding a second linkage signal source from within the area and the system, specifically for opening all pneumatic smoke exhaust windows in a unified manner, thereby greatly improving the sensitivity, reliability and integrity of the entire system.

[0029] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0030] See figure 1 This utility model provides a parallel pneumatic temperature control release system for a smoke exhaust window, including a linkage control box 1, a pressure gas cylinder 2, and a smoke exhaust window mechanism 3. The linkage control box 1 is connected to the pressure gas cylinder 2, the pressure gas cylinder 2 is connected to the smoke exhaust window mechanism 3 through a first pipe 21, and the smoke exhaust window mechanism 3 is connected to the linkage control box 1 through a second pipe 32.

[0031] Specifically, the linkage control box 1 can receive fire alarm linkage signals, daily ventilation remote centralized control signals, and fire feedback signals from outside the system, as well as signals sent from the smoke exhaust window mechanism 3. It processes these signals and sends control commands to the pressure cylinder 2 based on the processing results. It should be noted that the linkage control box 1 can regulate the pressure cylinder 2 in different ways according to the different signals received. The linkage control box 1 is connected to an AC 220V power supply from outside the system.

[0032] exist figure 1 In an optional embodiment, the pressure cylinder 2 is used to provide power to the pneumatic temperature control release device 33, which then further opens the pneumatic smoke exhaust window 31. There are multiple pressure cylinders 2, the specific number of which can be determined by those skilled in the art according to actual needs. Each pressure cylinder 2 is connected to the linkage control box 1, and the connection method can be, but is not limited to, cable connection.

[0033] Specifically, each pressure cylinder 2 contains compressed gas, which can be an inert gas. When the pressure cylinder 2 receives a start command from the linkage control box 1, the compressed gas is released. One end of the first pipe 21 is connected to the pressure cylinder 2, and the other end of the first pipe 21 is connected to the pneumatic temperature control release device 33. The first pipe 21 is a power transmission pipe, which can be used to transmit the compressed gas released from the pressure cylinder 2 to the pneumatic temperature control release device 33.

[0034] Furthermore, there are multiple smoke exhaust window mechanisms 3, with the specific number corresponding one-to-one with the number of pressure gas cylinders 2. Each smoke exhaust window mechanism 3 is connected to the corresponding pressure gas cylinder 2 through the first pipe 21.

[0035] exist figure 1 In an optional embodiment, the smoke exhaust window mechanism 3 includes multiple pneumatic temperature-controlled release devices 33. The specific number can be determined by those skilled in the art based on the site conditions. Each pneumatic temperature-controlled release device 33 controls one pneumatic smoke exhaust window. Each pneumatic temperature-controlled release device 33 is connected in parallel to the first pipe 21 and connected to the pressure gas cylinder 2. The connection method can be, but is not limited to, welding. It should be noted that the pressure gas cylinder 2 can release compressed gas, which is input into the pneumatic temperature-controlled release device 33 through the first pipe 21, and the pneumatic temperature-controlled release device 33 then drives the pneumatic smoke exhaust window 31 to open.

[0036] Meanwhile, when a fire occurs, the pneumatic temperature control release device 33 can detect the current ambient temperature. The smoke exhaust window mechanism 3 also includes a second pipe 32, and each pneumatic temperature control release device 33 is connected to the second pipe 32 at a connection point 34. The end of the second pipe 32 is connected to the linkage control box 1. The connection method can be, but is not limited to, welding. The second pipe 32 is a signal transmission pipe. When the pneumatic temperature control release device 33 detects a high ambient temperature, it immediately releases its built-in backup compressed gas. The compressed gas can be, but is not limited to, CO2. At the same time, the backup compressed gas flows along the second pipe 32 until it is transmitted to the linkage control box 1.

[0037] Furthermore, the second pipe 32 includes a first control valve 35 and a second control valve 36. Both the first control valve 35 and the second control valve 36 are one-way control valves. The first control valve 35 is located between two adjacent connection points 34 to ensure that compressed gas can be transmitted unidirectionally to the linkage control box 1. The second control valve 36 is located between the joints of every two sets of smoke exhaust window mechanisms 3 and the second pipe 32 to ensure that compressed air can be transmitted unidirectionally to the linkage control box 1.

[0038] The specific operating steps of the parallel smoke exhaust window pneumatic temperature control release system of this utility model are as follows:

[0039] First, the linkage control box 1 should receive power, air, and signal from outside the system, and then activate each pressure gas cylinder 2 to release compressed air to its corresponding smoke exhaust window mechanism 3, thereby opening all pneumatic smoke exhaust windows 31 in the area. However, when the power, air, and signal from outside the system are all in a state of failure, the linkage control box 1 cannot activate each group of pressure gas cylinders 2 in the first instance.

[0040] When the power, gas, and signal sources from outside the system are all in a state of failure, the pneumatic temperature control release device 33 configured in the pneumatic smoke exhaust window 31 closest to the fire source can first detect the high temperature exceeding the set threshold. The pneumatic temperature control release device 33 will be triggered and release backup compressed gas. Part of this backup compressed gas enters the pneumatic smoke exhaust window 31 and drives the pneumatic smoke exhaust window 31 to open. The other part serves as a pneumatic signal source and is transmitted to the linkage control box 1 through the second pipe 32. The linkage control box 1 receives the backup compressed gas signal from a certain pneumatic temperature control release device 33 through the second pipe 32.

[0041] When the linkage control box 1 receives a backup compressed gas signal from a certain pneumatic temperature control release device 33, it can control the corresponding pressure gas cylinders 2, so that the corresponding pressure gas cylinders 2 send compressed gas to each pneumatic temperature control release device 33 in the corresponding smoke exhaust window mechanism 3 through the first pipe 21. Each pneumatic smoke exhaust window 31 in the corresponding smoke exhaust window mechanism 3 is opened after receiving the compressed gas from the first pipe 21 through the pneumatic temperature control release device 33, thereby realizing the function of quickly opening all smoke exhaust windows in the area and ensuring the smoke exhaust speed and smoke exhaust volume.

[0042] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
