[0002] In modern society, natural gas, as an important energy carrier, is widely used in many fields such as residential life, industrial production and commercial services. With the popularization of natural gas, the problem of gas leakage has become increasingly prominent. Gas leakage can not only cause property damage, but also cause serious safety accidents such as fires and explosions, threatening people's lives and property.

[0003] Traditional gas leak detection methods often rely on regular manual inspections or simple gas alarm devices to alert people to gas leaks, thereby ensuring the safety of gas use. However, in actual use, manual inspections are time-consuming and labor-intensive, and cannot provide timely information about gas leaks. Furthermore, traditional gas leak alarm devices can only provide alarm signals but cannot automatically cut off the gas supply, requiring manual intervention, which reduces the complexity and safety of use.

[0004] In summary, this utility model provides an automatic gas leak shut-off device based on the Internet of Things to solve the above problems. Utility Model Content

Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0022] Example 1

[0023] like Figure 1-4 The image shows the first embodiment of this utility model, which provides an automatic gas leak blocking device based on the Internet of Things. The device includes a housing 100, a cover 110 installed at a gas pipeline joint and movably connected to the front of the housing 100 by bolts for sealing the housing 100, ventilation slots 120 formed at the upper and lower ends of the front of the cover 110 for airflow within the housing 100, an audible and visual alarm 130 installed on the front of the cover 110 for sound and light alarm, a microcontroller 140 located at the upper end of the inner cavity of the housing 100, a gas concentration sensor 150 located at the lower end of the inner cavity of the housing 100 for detecting the gas leak concentration, and a mobile phone connected to the output of the microcontroller 140 via a wireless transmission module; and a solenoid valve 200 installed on the surface of the gas pipeline for blocking the gas leak.

[0024] like Figure 1-4As shown, the vent 120 facilitates the entry of external gas into the enclosure 100. A gas concentration sensor 150 (model MIX1004) monitors the gas concentration inside the enclosure 100 in real time. Upon detecting an anomaly, the sensor immediately transmits a signal to the microcontroller 140 (model ESP32 series microcontroller). After receiving the signal, the microcontroller 140 quickly determines whether the gas concentration exceeds the safety threshold and controls the audible and visual alarm 130 (model LTE-5061) to issue an alarm, alerting on-site personnel. When the microcontroller 140 confirms that the gas leak has reached a dangerous level, it immediately sends a command to the solenoid valve 200 (model ASCO). The 8215G030 solenoid valve 200 quickly closes, cutting off the gas supply and effectively preventing safety accidents caused by gas leaks. Through the wireless transmission module, the microcontroller 140 can transmit gas concentration data and alarm information to a mobile phone in real time. Users can remotely view the gas usage, receive alarm information in a timely manner, and take corresponding emergency measures, thereby achieving efficient and intelligent gas leak monitoring and blocking, greatly improving the safety of gas use.

[0025] Example 2

[0026] Reference Figure 1 and 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, a power cord 160 is connected to the back of the cover 100, and a power plug is connected to the other end of the power cord 160. The output terminal of the microcontroller 140 is connected to the input terminal of the audible and visual alarm 130 and the solenoid valve 200, respectively. The output terminal of the gas concentration sensor 150 is connected to the input terminal of the microcontroller 140.

[0028] like Figure 1 and 4 As shown, the power cord 160, along with the power plug, can be easily connected to a home or industrial power system without the need for an additional power supply, ensuring a stable and reliable power supply and stable operation of electrical components. The microcontroller 140 serves as the control core of the entire device, with its output connected to the input of the audible and visual alarm 130 and the solenoid valve 200, and its input connected to the output of the gas concentration sensor 150. This connection method ensures that the microcontroller 140 can promptly control the audible and visual alarm 130 to sound an alarm based on the signal provided by the gas concentration sensor 150, and instruct the solenoid valve 200 to shut off the gas supply, thereby effectively preventing safety accidents caused by gas leaks.

[0029] Example 3

[0030] Reference Figure 2 and 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0031] In this embodiment, a limiting strip 111 is fixedly connected to the back of the cover 110. The limiting strip 111 is located in the inner cavity of the cover 100 and is movably connected to the inner cavity of the cover 100. A filter screen 121 is fixedly connected to the upper and lower ends of the back of the cover 110 and to the back of the ventilation groove 120.

[0032] A placement seat 141 is fixedly connected to the upper end of the back side of the inner cavity of the cover 100. The microcontroller 140 is located in the inner cavity of the placement seat 141 and is engaged with the placement seat 141.

[0033] A connecting seat 151 is fixedly connected to the lower end of the back side of the inner cavity of the cover 100. The rear end of the gas concentration sensor 150 extends into the inner cavity of the connecting seat 151 and is threadedly connected to the inner cavity of the connecting seat 151.

[0034] like Figure 2 and 3 As shown, the limiting strip 111 ensures that the cover 110 is accurately positioned on the housing 100 when closed, and the filter screen 121 is designed to filter the air entering the housing 100, preventing impurities and dust from interfering with the operation of the gas concentration sensor 150. The mounting base 141 provides a stable mounting position for the microcontroller 140, and the design of the mounting base 141 and the snap-fit ​​structure ensures the stability of the microcontroller 140 during device operation, while also facilitating installation and disassembly. The design of the connecting base 151 and the threaded connection structure ensures the stability of the gas concentration sensor 150 during device operation, and the threaded connection structure makes the replacement of the gas concentration sensor 150 more convenient.

[0035] In use, first, the housing 100 is bolted to the gas pipe joint to ensure a secure installation. The solenoid valve 200 is then installed on the gas pipe surface and the control circuit is connected. Next, the power plug is connected, and the power cord 160 supplies power to the electrical components inside the housing 100. When monitoring for gas leaks, external gas enters the inner cavity of the housing 100 through the vent 120. The gas concentration sensor 150 monitors the gas concentration inside the housing 100 in real time and transmits the data to the microcontroller 140. The microcontroller 140 receives the data... The system compares the data with a preset safety threshold to determine if the gas concentration is abnormal, thus enabling real-time monitoring of gas leaks. If the gas concentration exceeds the safety threshold, the microcontroller 140 immediately controls the audible and visual alarm 130 to issue an audible and visual alarm and sends the alarm information to a mobile phone via a wireless transmission module, thereby enabling timely warnings. At the same time, the microcontroller 140 can send a command to the solenoid valve 200, which quickly closes to cut off the gas supply, effectively preventing safety accidents caused by gas leaks. This achieves efficient and intelligent gas leak monitoring and blocking, greatly improving the safety of gas use.
