Description

Technical Field

[0001] This utility model relates to the field of combustible gas detection technology, and in particular to a combustible gas alarm for a remote outdoor meter box in a multi-story building. Background Technology

[0002] With the acceleration of urbanization and the popularization of high-rise buildings, the gas supply system of multi-story buildings is becoming increasingly complex, and its safety issues are receiving more and more attention from all sectors of society. Traditional gas safety protection measures mainly rely on combustible gas alarms installed in users' homes, but there are obvious limitations. First, the alarm signals are usually limited to local sound and light prompts, making it difficult to achieve linkage control. Once users are not at home or fail to notice in time, it is easy to miss the best time to deal with the situation. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0004] Multi-story building remote outdoor meter box combustible gas alarm, including:

[0005] Meter box, in which a main gas pipeline is fixedly inserted, the main gas pipeline is connected to each gas meter through several gas branch pipes, each gas branch pipe is equipped with an outdoor solenoid valve, the solenoid valve is electrically connected to a wireless signal receiver, each gas meter is connected to its own meter back pipe, and each group of meter back pipes passes through into the corresponding building floor.

[0006] The detection component is wirelessly connected to the solenoid valve via a receiver.

[0007] As an improvement to the above technical solution, the detection component includes a housing, a detection end is provided at the bottom of the housing, a communication end is provided at one side of the housing, a transmitter is electrically connected to the communication end, the transmitter and the receiver are connected wirelessly, and a controller is provided inside the housing, which is electrically connected to the communication end and the detection end respectively.

[0008] As an improvement to the above technical solution, an alarm terminal is installed on one side of the housing, and the alarm terminal is electrically connected to the controller.

[0009] As an improvement to the above technical solution, the pipe behind the meter is a stainless steel flexible hose for gas transmission.

[0010] The beneficial effects of this utility model are:

[0011] The detection component continuously monitors the air environment in each floor's user area and can capture changes in combustible gas concentration in real time. Once the preset safety threshold is exceeded, it can instantly trigger wireless command transmission. After receiving the command, the wireless signal receiver immediately controls the outdoor solenoid valve to close. The entire linkage process requires no manual intervention and achieves "second-level response." Compared with the traditional lag mode of manually closing the valve, it can cut off the gas source before the meter in the early stage of leakage, fundamentally avoiding safety accidents such as explosions and poisoning caused by the accumulation of leakage, and significantly improving the inherent safety level of gas use in multi-story buildings.

[0012] Outdoor solenoid valves are installed on each gas branch pipe according to the principle of one valve per household. The gas supply to the corresponding branch pipe is cut off only for the user with a leak. The main gas pipe and the gas branch pipes of other users without leaks continue to supply gas normally, which eliminates the problem of gas outage for the entire building due to a leak in a single household and achieves a balance between precise risk control and ensuring normal gas use for the majority of users.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Multi-story building remote outdoor meter box combustible gas alarm, including:

[0018] The meter box contains a fixed gas main pipe 10, which is connected to a gas meter 11 via several gas branch pipes 15. Each gas branch pipe 15 is equipped with an outdoor solenoid valve 12, which is electrically connected to a wireless signal receiver 13. Each gas meter 11 is connected to its own meter back pipe 14, and each set of meter back pipes 14 passes through into the corresponding building floor.

[0019] The detection component 20 is wirelessly connected to the solenoid valve 12 via the receiver 13.

[0020] Specifically, the meter box is installed outdoors. The main gas pipeline 10 is introduced from the municipal pipeline into the main gas pipeline. Gas branch pipelines 15 branch off from the main gas pipeline 10, each leading to a user on a different floor. The gas meter 11 measures the gas consumption of each user. Outdoor solenoid valves 12 are installed on each gas branch pipeline 15 to control the gas supply to each user. This is a key component for implementing safety shut-off. The wireless signal receiver is electrically connected to each outdoor solenoid valve 12 to receive wireless control signals from the detection component 20. The post-meter pipe 14 connects to the outlet of the gas meter 11, passes through the wall into the respective building floor, and leads to the user's home. Under normal circumstances, all outdoor solenoid valves 12 are open, and gas flows through the main gas pipeline 10, gas branch pipelines 15, gas meter 11, post-meter pipe 14, and into each user's home for normal use. The wireless signal receiver 13 is in standby mode, listening for signals from the detection component 20. The detection component continuously monitors the air environment of each user on each floor. When a gas leak occurs in any user's home, the system will detect the leak. When the gas concentration in the air increases, the detection component 20 will detect an increase in the concentration of combustible gas. When the detected gas concentration exceeds the preset safety threshold, the detection component 20 will be triggered. The detection component 20 will wirelessly send a closing command to the wireless signal receiver 13 on the corresponding outdoor solenoid valve 12 connected to the user with the leak. After receiving the command, the wireless signal receiver 13 will immediately control the outdoor solenoid valve 12 connected to it to perform the closing action. After the solenoid valve 12 is closed, the gas supply from the main gas pipe 10 through the gas branch pipe 15 to the gas meter 11 will be cut off. Since the gas source before the gas meter is cut off, even if there is a leak in the pipes or stove in the user's home, no new gas can flow in, thus fundamentally preventing the expansion of the leak source. The two achieve non-contact, remote and rapid linkage through wireless signals, realizing automatic cutting off of the gas source at the source when a gas leak occurs, which greatly improves the safety of gas use in multi-story buildings.

[0021] In one embodiment, the detection component 20 includes a housing 21, a detection end 22 is provided at the bottom of the housing 21, and a communication end 25 is provided at one side of the housing 21. A transmitter 251 is electrically connected to the communication end 25, and the transmitter 251 is wirelessly connected to the receiver 13. A controller 23 is provided inside the housing 21, and the controller 23 is electrically connected to both the communication end 25 and the detection end 22. The sensor in the detection end 22 detects the concentration of combustible gas in the air and transmits the concentration signal to the controller 23. The controller 23 compares the current concentration with a preset safety threshold. When the detected gas concentration exceeds the preset safety threshold, the controller 23 is triggered and sends a shutdown command to the transmitter 251 through the communication end 25. The transmitter 251 converts the command into a wireless signal, and the corresponding wireless signal receiver 13 receives the shutdown command sent by the transmitter 251.

[0022] In one embodiment, an alarm terminal 24 is installed on one side of the housing 21. The alarm terminal 24 is electrically connected to the controller 23. When the controller 23 determines that there is a risk of leakage, it will perform two key actions simultaneously. The controller 23 sends a signal to the alarm terminal 24 to trigger an audible and visual alarm. A high-decibel alarm sound and a flashing warning light will sound and light up in the user's home, reminding the user to pay attention to the emergency situation of gas leakage and to immediately move away from the danger zone. The controller 23 drives the transmitter 251 through the communication terminal 25 to send the shutdown command in the form of a wireless signal.

[0023] In one embodiment, the pipe 14 after the meter is a stainless steel flexible hose for gas delivery. Gas is safely and stably delivered from the gas meter to the gas appliances in the user's home through the stainless steel flexible hose for gas delivery. This type of hose itself greatly reduces the risk of leakage caused by hose aging, damage, detachment or being bitten by rodents.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
