Description

Technical Field

[0001] This utility model relates to the field of gas safety equipment technology, and in particular to a gas active safety defense device. Background Technology

[0002] Gas is widely used in residential life, but it also poses safety risks such as leaks, explosions, and fires.

[0003] Currently, the main measures for gas safety protection for residential users in China are to install combustible gas detectors and solenoid valves for leak protection. However, the stability of combustible gas detectors is greatly affected by the usage environment and life cycle, and their functions are limited. Even if a qualified detector is triggered when it detects a gas leak, the gas concentration has already reached a certain level, and it cannot shut off the gas pipeline in time when the leak occurs. Many uncertain factors may lead to accidents afterward. Utility Model Content

[0004] To address the above deficiencies, the purpose of this utility model is to provide a gas active safety defense device. This gas active safety defense device can detect gas pipeline data in real time, promptly identify abnormalities such as underpressure, overpressure, excessive gas flow, leakage, and earthquakes in the gas pipeline, and actively cut off the gas pipeline, greatly improving the safety of gas use.

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

[0006] An active gas safety protection device includes a housing. An inlet pipe is located on one side of the housing, and an outlet pipe is located on the other side of the housing. One end of the inlet pipe and the outlet pipe extends out of the housing and connects to a gas pipeline inlet pipe and a gas pipeline outlet pipe, respectively. The other end of the inlet pipe and the outlet pipe extends out of the housing and connects to a gas meter. A valve is installed on the inlet pipe, and a pressure sensor before and after the valve is installed on the inlet pipe on both sides of the valve, respectively. A flow sensor is installed on the outlet pipe.

[0007] The housing also houses a controller assembly, and the upstream pressure sensor, downstream pressure sensor, flow sensor, and valve actuator are all electrically connected to the controller assembly.

[0008] The housing also houses a battery assembly, and the controller assembly is electrically connected to the battery assembly.

[0009] The housing is provided with an external power interface for connecting to mains power, and the external power interface is electrically connected to the battery assembly.

[0010] The housing is provided with an expansion interface, which is electrically connected to the controller assembly.

[0011] The housing is provided with a data transmission interface, which is electrically connected to the controller assembly.

[0012] The housing is equipped with a display screen, which is electrically connected to the controller assembly and the battery assembly.

[0013] The display screen is mounted on the housing located between the air inlet pipe and the air outlet pipe.

[0014] The two ends of the air inlet pipe are respectively sealed and connected to the air inlet pipe of the gas pipeline and the air inlet end of the gas meter through loose nuts, and the two ends of the air outlet pipe are respectively sealed and connected to the air outlet pipe of the gas pipeline and the air outlet end of the gas meter through loose nuts.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] The present invention's active gas safety defense device includes a housing, with an inlet pipe on one side of the housing and an outlet pipe on the other side. One end of the inlet and outlet pipes passes through the housing and connects to the gas pipeline inlet and outlet pipes, respectively. The other end of the inlet and outlet pipes passes through the housing and connects to the gas meter. A valve is installed on the inlet pipe, and a pressure sensor before and after the valve is installed on the inlet pipes located on both sides of the valve. A flow sensor is installed on the outlet pipe. This utility model of an active gas safety protection device is installed between the gas pipeline and the gas meter. It cleverly integrates a pressure sensor, a flow sensor, and a solenoid valve into a single device, along with a microcomputer controller. The pressure and flow sensors can more accurately detect the gas pressure and flow rate. Based on changes in the pressure and flow data collected by each sensor, it can determine the gas usage status and provide safety protection functions. In case of unsafe conditions such as underpressure, overpressure, excessive gas flow, leakage, or strong vibrations such as earthquakes, it can promptly control the valve actuator to shut off the valve. It will also shut off the valve if the user is not using gas during a certain period or if the user's gas usage is deemed too long and a risk is detected. Furthermore, it can periodically or upon command perform gas tightness checks on the user's pipeline and upload the detected pressure data in real time. This integrated design enables multiple functions to work together, greatly improving the safety of gas use. At the same time, this utility model of an active gas safety protection device has a compact layout, small size, and is easy to install and use.

This utility model of active gas safety protection device can detect gas pipeline data in real time, and can promptly determine abnormalities such as gas pipeline underpressure, overpressure, excessive gas flow, leakage, earthquake, etc., and actively cut off the gas pipeline, greatly improving the safety of gas use.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] The directions mentioned in this manual are based on the directions shown in the attached diagram and represent only relative positional relationships, not absolute positional relationships.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a gas active safety protection device includes a housing 10. An inlet pipe 22 is provided on one side of the housing 10, and an outlet pipe 27 is provided on the other side of the housing 10. The inlet pipe 22 and the outlet pipe 27 are arranged in parallel. One end of both the inlet pipe 22 and the outlet pipe 27 extends out of the housing 10. The end of the inlet pipe 22 extends out of the housing 10 and connects to a gas pipeline inlet pipe 70, and the end of the outlet pipe 27 extends out of the housing 10 and connects to a gas pipeline outlet pipe 72. The other ends of the inlet pipe 22 and the outlet pipe 27 extend out of the housing 10 and connect to a gas meter 80. Gas enters the inlet pipe 22 from the gas pipeline inlet pipe 70, then enters the gas meter 80, passes through the metering component of the gas meter 80, and then enters the outlet pipe 27, and finally enters the gas pipeline outlet pipe 72 for user use.

[0026] As shown in the figure Figure 3 As shown, a valve 40 is installed in the middle of the intake pipe 22. A pre-valve pressure sensor 50 and a post-valve pressure sensor 52 are respectively installed on the intake pipe 22 on both sides before and after the valve 40. In this embodiment, the end of the intake pipe 22 connected to the gas pipeline intake pipe 70 is defined as the front side of the valve 40, and the end of the intake pipe 22 connected to the gas meter 80 is defined as the rear side of the valve 40. A flow sensor 54 is installed on the outlet pipe 27. Preferably, the valve 40 is a solenoid valve, and the flow sensor 54 is a thermal flow sensor. Thermal flow sensors offer good stability and do not produce false readings of small flow rates. They also effectively utilize part of the space in the outlet pipe 27, making the spatial layout of this invention more compact.

[0027] like Figure 2 and Figure 3As shown, a controller assembly 32 is also installed inside the housing 10. The upstream pressure sensor 50, the downstream pressure sensor 52, the flow sensor 54, and the valve actuator 42 of the valve 40 are all electrically connected to the controller assembly 32. The upstream pressure sensor 50 and the downstream pressure sensor 52 transmit the real-time detected pressure data to the controller assembly 32. The microcontroller chip in the controller assembly 32 calculates the pressure difference before and after the valve based on the obtained pressure data. At the same time, it compares the real-time pressure values ​​before and after the valve and the pressure difference with the set value. When the obtained actual value deviates from the set value, it can be determined that the pressure is abnormal (underpressure or overpressure, etc.). When the pressure is determined to be abnormal, the controller assembly 32 will issue a valve closing command to the valve actuator 42. After receiving the command, the valve actuator 42 will immediately close the valve 40 and cut off the gas pipeline. Simultaneously, as the gas passes through the flow sensor 54, the flow sensor 54 transmits the collected flow value to the controller component 32. The controller component 32 compares the obtained real-time flow value with the set value and can promptly determine whether the flow is abnormal (such as overflow). If an abnormal flow is detected, it will also control the valve actuator 42 to close the valve 40, cutting off the gas pipeline. By real-time detection of pressure and flow in the pipeline, changes in pressure and flow can be understood in a timely manner, thereby promptly detecting whether a gas leak has occurred. Closing the valve 40 immediately upon detection of a leak can effectively avoid safety hazards caused by gas leaks and improve the safety of gas use.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a battery assembly 30 is also installed inside the housing 10. The battery assembly 30 is electrically connected to the controller assembly 32, the pre-valve pressure sensor 50, the post-valve pressure sensor 52, the flow sensor 54, and the valve actuator 42. The battery assembly 30 provides power to the controller assembly 32, the pre-valve pressure sensor 50, the post-valve pressure sensor 52, the flow sensor 54, and the valve 40. The housing 10 is provided with an external power interface 16 for connection to mains power. The external power interface 16 is electrically connected to the battery assembly 30, allowing this invention to be powered by mains power or by the battery in the battery assembly 30. While using mains power, the battery assembly 30 can also be charged, flexibly adapting to various on-site situations.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, the housing 10 is provided with an expansion interface 14, which is electrically connected to the controller assembly 32. The expansion interface 14 can be connected to gas safety equipment such as a combustible gas alarm (not shown in the figure) and receive the signal from the combustible gas alarm. When the combustible gas alarm is triggered, the controller assembly 32 can promptly control the valve actuator 42 to close the valve 40, thus providing multiple safety protection functions.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the housing 10 is equipped with a data transmission interface 12, which is electrically connected to the controller assembly 32. The data transmission interface 12 can be connected to a wireless module, enabling real-time data communication with external devices or a monitoring center. This eliminates the need for traditional wired connections, increases the flexibility of the installation location of the protection device, and allows users to remotely monitor the gas safety status via mobile devices such as smartphones.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a display screen 60 is mounted on the housing 10. The display screen 60 is electrically connected to the controller assembly 32 and the battery assembly 30. The display screen 60 is used to display the pressure value, flow value, and alarm information of the gas pipeline. In this embodiment, the display screen 60 is preferably installed on the housing 10 between the inlet pipe 22 and the outlet pipe 27, that is, the display screen 60 is installed in the center of the housing 10, which facilitates operation and observation, and also makes reasonable use of the internal space of the housing 10.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the two ends of the air inlet pipe 22 are respectively sealed to the air inlet pipe 70 of the gas pipeline and the air inlet end of the gas meter 80 through the loose nut 90, and the two ends of the gas outlet pipe 27 are respectively sealed to the gas outlet pipe 72 of the gas pipeline and the gas outlet end of the gas meter 80 through the loose nut 90. The installation is convenient and the airtightness is good.

[0033] In summary, this utility model of active gas safety protection device can detect gas pipeline data in real time, promptly identify abnormalities such as underpressure, overpressure, excessive gas flow, leakage, and earthquakes, and actively cut off the gas pipeline, greatly improving the safety of gas use.

[0034] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
