Description

Technical Field

[0001] The utility model belongs to the technical field of gas monitoring, and in particular relates to an exhaust structure in a patio of a high-rise residential building and a gas safety monitoring system. Background Art

[0002] In recent years, high-rise residential buildings with inner patio structures have gradually appeared, and the inner patio has become the main channel for residential users to discharge flue gas using gas water heaters. However, when the gas water heater burns incompletely, the flue gas produced contains a large amount of harmful gases such as carbon monoxide, nitrogen oxides, and methane. Due to the relatively closed structure of the patio, harmful gases are easily accumulated in the patio and difficult to disperse. In addition, the gas may use the "chimney effect" to enter the homes of surrounding residents through the windows opened in the inner patio. When the human body inhales excessive flue gas, it will cause dizziness, fatigue, and even suffocation, posing a threat to the life safety of residents. Therefore, the gas safety issue in the patio of high-rise residential users has become a focus of common concern for gas users and gas safety management departments.

[0003] At present, most of the exhaust modules in the prior art only use one exhaust port and exhaust fan, such as an underground garage carbon monoxide concentration monitoring system disclosed in the invention patent with announcement number CN211978846U. However, since the air volume in the patio in a high-rise residential building is large and the light harmful gases will drift upward after being discharged, if only one exhaust inlet is set at the bottom of the patio, almost all the air in the space needs to be discharged each time to meet the gas safety standard, and the exhaust efficiency is low. Therefore, there is still a need for further improvement of the prior art. Summary of the invention

[0004] The utility model aims to provide an exhaust structure and a gas safety monitoring system in a high-rise residential patio, which can quickly detect abnormal gas data areas and discharge the gas in time through the arrangement of gas sensors and exhaust fans at the inlet of the exhaust duct, thereby avoiding the accumulation of harmful gases in the patio.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] An exhaust structure in the patio of a high-rise residential building.

[0007] The invention comprises a plurality of outdoor gas sensors and an exhaust mechanism, wherein the plurality of outdoor gas sensors are arranged on the outer wall of a building, the exhaust mechanism comprises an exhaust duct, a main exhaust fan and a plurality of exhaust duct inlet exhaust fans, the exhaust duct is arranged on the outer wall of the building, the exhaust duct comprises an exhaust duct outlet and a plurality of exhaust duct inlets, the exhaust duct outlet and the main exhaust fan are arranged at the top of the exhaust duct, the exhaust duct inlet is opened along the exhaust duct, the plurality of exhaust duct inlet exhaust fans are arranged on the wall of the building, and the air exhaust port of the exhaust duct inlet exhaust fan is directly opposite to the exhaust duct inlet.

[0008] Preferably, a plurality of outdoor gas sensors and exhaust duct inlets are evenly arranged along the outer wall of the building.

[0009] Preferably, the number of exhaust duct inlets is the same as the number of outdoor gas sensors.

[0012] Preferably, it further comprises a plurality of alarm devices, which are evenly arranged on the outer wall of the building, and the installation positions correspond one-to-one to the plurality of outdoor gas sensors.

[0013] The present application also provides a gas safety monitoring system in a high-rise residential patio, which has the above-mentioned exhaust structure and also includes a management module and a communication module. The signal output end of each outdoor gas sensor is connected to the management module via the communication module, and the main exhaust fan, the exhaust duct inlet exhaust fan, and the controlled end of the alarm device are connected to the signal output end of the management module via the communication module.

[0026] The present invention is further described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The terms such as "upper", "lower", "left", "right" and the like cited in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of the relative relationship shall also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0027] Embodiment 1

[0028] This embodiment provides an exhaust structure in the patio of a high-rise residential building, such as Figure 1 As shown, it includes multiple outdoor gas sensors 3 and exhaust mechanisms. Each outdoor gas sensor 3 is arranged on the outer wall of the building to detect gas data in different areas. The outdoor gas sensor 3 can be selected according to the application scenario requirements, such as carbon monoxide gas sensor, methane gas sensor, nitrogen oxide gas sensor. The exhaust mechanism includes an exhaust duct 4, a main exhaust fan 2 and multiple exhaust duct inlet exhaust fans 7. The exhaust duct 4 is arranged on the outer facade of the building. The exhaust duct 4 includes an exhaust duct outlet 5 and multiple exhaust duct inlets 6. Figure 2 As shown, the exhaust duct outlet 5 and the main exhaust fan 7 are arranged at the top of the exhaust duct 4. The exhaust duct inlet 6 is opened along the exhaust duct 4. Figure 3 As shown, each exhaust fan 7 at the exhaust duct inlet is arranged on the building wall, and the air outlet of the exhaust fan 7 at the exhaust duct inlet is directly opposite to the exhaust duct inlet 6. Preferably, the outdoor gas sensors 3 and the exhaust fans 7 at the exhaust duct inlet are evenly arranged on the outer wall of the building in the patio, and the number of the outdoor gas sensors 3 and the exhaust fans 7 at the exhaust duct inlet is the same, and the exhaust fans 7 at the exhaust duct inlet correspond to the positions of each outdoor gas sensor 3. Each pair of outdoor gas sensors 3 and exhaust fans 7 at the exhaust duct inlet can work in conjunction to discharge the abnormal gas exceeding the standard in the area.

[0029] In this embodiment, multiple outdoor gas sensors 3 and exhaust fans 7 at the inlet of exhaust ducts are evenly arranged on the outer wall of the building in the patio, thereby indirectly dividing the space in the patio into multiple areas. When an outdoor gas sensor first detects abnormal data, the exhaust fan 7 at the inlet of exhaust ducts and the main exhaust fan 2 closest to it are turned on. The exhaust fan 7 at the inlet of exhaust ducts and the main exhaust fan 2 cooperate to draw air, so as to quickly suck the air in the high concentration area of ​​toxic and harmful gases in the patio through the exhaust duct inlet 6, and guide the airflow through the exhaust duct 4 to be discharged to the top exhaust duct outlet 5.

[0030] Embodiment 2

[0031] like Figure 4As shown, a gas safety monitoring system in a high-rise residential courtyard includes an exhaust structure in a high-rise residential courtyard as provided in Example 1, and also includes a management module and a communication module. The signal output ends of multiple outdoor gas sensors are connected to the management module through the communication module, and the controlled ends of the main exhaust fan and the exhaust fan at the inlet of the exhaust duct are connected to the signal output end of the management module through the communication module. When the exhaust fan 7 at the inlet of the exhaust duct corresponds to each outdoor gas sensor 3, the management module controls the outdoor gas sensor 3 and the exhaust fan 7 at the inlet of the exhaust duct corresponding to each other in position. When the number or installation position of the exhaust fan 7 at the inlet of the exhaust duct is different from that of each outdoor gas sensor 3, the management module can schedule the exhaust fan 7 at the inlet of the exhaust duct closest to the outdoor gas sensor 3 to start exhaust. The communication module can choose to use local area network, wifi or 3G\4G\5G and other methods to realize information transmission between module devices.

[0032] In this embodiment, the outdoor gas sensor 3 can adopt a carbon monoxide gas sensor, the management module is a property data monitoring management center, the communication module adopts 4G wireless network remote transmission, and the outdoor carbon monoxide concentration safety threshold in the patio is set to 10mg / m3 (national standard value).

[0033] A carbon monoxide gas sensor is set every three floors in the patio, and an exhaust duct inlet 6 and an exhaust duct inlet exhaust fan 7 are also set every three floors in the exhaust duct. The carbon monoxide gas sensor is used to detect the carbon monoxide concentration in the smoke emitted from the combustion of the household gas water heater to the inner patio, and convert the concentration signal into an analog signal for remote transmission through the 4G wireless network. The property data monitoring and management center receives the signal for processing and analysis to determine whether it is greater than the set safety threshold. When the carbon monoxide concentration detected by the carbon monoxide gas sensor at any position is greater than 10mg / m3, the property data monitoring and management center controls the main exhaust fan 2 of the exhaust mechanism and the exhaust duct inlet exhaust fan 7 linked to the carbon monoxide gas sensor 3 through the 4G wireless network remote transmission to start at the same time. The exhaust duct inlet exhaust fan 7 cooperates with the main exhaust fan 2 to suck the airflow, which can quickly suck the air in the high carbon monoxide concentration area in the patio through the exhaust duct inlet 6, and guide the airflow through the exhaust duct 4 to be discharged at the top exhaust duct outlet 5. The exhaust fan parameters can be set to automatically start ventilation at 12 times / h until the carbon monoxide concentration in the area drops below the national standard value of 10mg / m3, and the exhaust fan 7 and the main exhaust fan 2 at the exhaust duct inlet are closed.

[0034] In this embodiment, the property data monitoring and management center implements regional control of the space in the patio according to the arrangement of the carbon monoxide gas sensor and the exhaust fan 7 at the exhaust duct inlet in the patio. When the property data monitoring and management center first receives abnormal data detected by the carbon monoxide gas sensor in a certain area, it can promptly analyze the area with abnormal carbon monoxide concentration in the patio, and quickly dispatch the nearest exhaust duct inlet exhaust fan 7 main exhaust fan 2 to start suction in time to avoid the accumulation of harmful gases in the patio.

[0035] Embodiment three:

[0036] like Figure 5 As shown, in order to promptly remind residents to check for potential safety hazards in household appliances, the difference between this embodiment and the second embodiment is that:

[0037] In this embodiment, the outdoor gas sensor 3 uses a nitrogen oxide gas sensor, and also includes an alarm module and an intelligent terminal device, wherein the alarm module is an audible and visual alarm, and the controlled end of the audible and visual alarm is remotely transmitted through a 4G wireless network to connect to the signal output end of the property data monitoring management center, which is used to remind residents to check their household devices. The management module remotely transmits the abnormal concentration data to the intelligent terminal device in real time through the 4G wireless network, and the intelligent terminal device is one of a smart phone, a portable computer, and a tablet computer.

[0038] The number of sound and light alarms is the same as the number of nitrogen oxide gas sensors and pipeline inlet exhaust fans 7, and the installation positions of the sound and light alarms correspond one-to-one with the positions of the nitrogen oxide gas sensors and pipeline inlet exhaust fans 7. When the property data monitoring and management center detects that the nitrogen oxide gas sensor exceeds the safety threshold, the management module controls the sound and light alarm to automatically turn on. At the same time, the property data monitoring and management center remotely transmits the abnormal data in the form of text messages through the 4G wireless network to the mobile phones of the residents on the floors in the area covered by the carbon monoxide gas sensor 3.

[0039] Due to the arrangement of the outdoor gas sensor 3 and the exhaust fan 7 at the exhaust duct inlet, the space in the patio is also indirectly divided into multiple areas. When the outdoor gas sensor 3 in a certain area first detects abnormal data, in order to avoid safety hazards, the property data monitoring and management center can lock the floor range of the area where nitrogen oxides exceed the standard and turn on the alarm device, so as to promptly remind the residents covered by the area to promptly check whether there are safety hazards such as insufficient combustion in the household water heater, greatly reducing the scope of inspection and improvement of work efficiency.

[0040] Embodiment 4:

[0041] like Figure 6 As shown, in order to prevent the smoke containing carbon monoxide in the inner courtyard from entering the residents' homes and causing harm to people, the difference between this embodiment and the second and third embodiments is that:

[0042] It also includes indoor gas sensors 8 and intelligent range hoods 9. The number of indoor gas sensors 8 and intelligent range hoods 9 is the same and they are installed in the same space. The property data monitoring management center controls the indoor gas sensors 8 and intelligent range hoods 9 in the same space in a linkage manner. Figure 7 As shown, in this embodiment, the indoor gas sensor 8 and the outdoor gas sensor 3 are both carbon monoxide gas sensors. The indoor carbon monoxide sensor transmits the monitored indoor carbon monoxide concentration information to the property data monitoring management center. The property data monitoring management center determines whether there is an abnormality in the indoor carbon monoxide gas concentration, and outputs the indoor carbon monoxide concentration abnormality signal to the controlled end of the intelligent range hood 9. The intelligent range hood 9 is used to discharge the indoor air to the outside. The controlled end of the intelligent range hood 9 is connected to the signal output end of the property data monitoring management center. The indoor carbon monoxide gas sensor 8 collects the carbon monoxide gas concentration in the kitchen smoke and converts the concentration signal into an analog signal. The property data monitoring management center receives the signal for processing and analyzes the processed information to determine whether the concentration is greater than the safety threshold. When the carbon monoxide gas sensor in any indoor space detects that the carbon monoxide concentration is greater than 10mg / m3, the property data monitoring management center controls the intelligent range hood 9 linked to the indoor gas sensor 8 to start and discharge the indoor air until the indoor carbon monoxide concentration value drops below 5mg / m3.

[0043] Furthermore, the property data monitoring and management center can also compare the indoor carbon monoxide concentration data with the outdoor carbon monoxide data. If the indoor carbon monoxide concentration is greater than or equal to the outdoor carbon monoxide concentration, the property data monitoring and management center will send a text message to remind "Please check whether there is carbon monoxide leakage in the indoor equipment in time." If the outdoor carbon monoxide concentration is greater than the indoor carbon monoxide concentration, the property data monitoring and management center will send a text message to remind "The carbon monoxide concentration in the patio is high. Please temporarily close the patio side windows and open the doors and windows in other directions for timely ventilation."

[0044] In this embodiment, by installing indoor gas sensors 8 and intelligent range hoods 9 in residents' homes, the property data monitoring and management center compares indoor and outdoor data in a timely manner, promptly reminds residents to pay attention to protection, and further ensures the safety of the residents' living environment.

[0045] Finally, the multiple embodiments described in this application are only a part of the embodiments of the utility model, not all of the embodiments. The terms such as "carbon monoxide gas sensor", "nitrogen oxide gas sensor", "4G wireless network remote transmission" and the like cited in this specification, as well as the number and installation location of the outdoor gas sensor and the exhaust fan at the inlet of the exhaust duct are only for the convenience of description, and are not used to limit the scope of implementation of the indoor gas sensor, outdoor gas sensor, exhaust fan at the inlet of the exhaust duct, and communication module types of the utility model. Those skilled in the art should know that there are many types of gas sensors and communication module transmission methods, which should also be regarded as the scope of implementation of the utility model without substantial changes in the technical content.

[0046] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the protection scope of the present utility model patent application.
