Description

Technical Field

[0001] This utility model relates to the field of gas pipeline leak detection technology, specifically a gas pipeline leak alarm and exhaust device. Background Technology

[0002] In the gas pipeline system of old residential areas, the control valve is a key component for controlling the gas supply and demand. The risk of its location is particularly prominent. Due to long-term use, the control valve itself may wear out or become loose, resulting in poor sealing and gas leakage.

[0003] Once a leak occurs, the gas will accumulate rapidly. When the concentration reaches the explosive limit, it can easily cause an explosion when it comes into contact with an open flame, electric spark, or other ignition source, posing a huge threat to the lives and property of the residents in the community. Utility Model Content

[0004] This utility model aims to provide an alarm and ventilation device specifically for detecting gas pipeline leaks.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a gas pipeline leak alarm and ventilation device, comprising a pipeline body, a control valve provided on the pipeline body, a base provided on the lower side of the control valve, a pair of connecting plates connected to the upper side of the base by screws, a semi-circular hole corresponding to the pipeline body provided in the middle part of the connecting plate, a bearing plate connected to the upper side of the connecting plate by screws, and a detection component provided between the bearing plate and the base;

[0006] The support plate is U-shaped, and a connecting seat is provided on the upper side of the support plate. An exhaust fan is provided on the upper side of the connecting seat. The four corners of the connecting seat are connected to the upper side of the support plate by screws. A control module is provided on the connecting seat, and a wireless signal transmitting module is provided on the upper side of the connecting seat.

[0007] Preferably, the detection component includes a vertical plate, the upper side of which is connected to the lower side of the support plate, the lower side of which is in close contact with the upper side of the base, and a gas detector is provided on the inner side of the vertical plate.

[0008] Preferably, the base is provided with a first reinforcing rib, and the underside of the support plate is provided with a second reinforcing rib.

[0009] Preferably, a delivery pipe is connected to one side of the exhaust fan.

[0010] Preferably, a buzzer alarm is provided on the support plate.

[0011] This utility model provides a gas pipeline leak alarm and exhaust device with the following advantages: By installing the gas detector inside the vertical plate, and with the vertical plate tightly connected to the support plate and base, it can be accurately positioned near the control valve to detect gas leaks in real time and accurately. Once a gas leak is detected, the buzzer alarm on the support plate will immediately sound an alarm to alert nearby residents. At the same time, the control module will immediately start the exhaust fan to quickly exhaust the leaked gas outdoors through the delivery pipe, reducing the indoor gas concentration and preventing the danger from escalating further. The leak information will also be quickly sent to relevant management platforms and rescue departments via the wireless signal transmission module, achieving multi-level early warning. This accurate detection and timely early warning mechanism effectively reduces the risk of explosion accidents and protects the lives and property of residents. Attached Figure Description

[0016] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figure 1-3 As shown, a gas pipeline leak alarm and ventilation device includes a pipeline body 1, a control valve 2 is provided on the pipeline body 1, a base 3 is provided on the lower side of the control valve 2, a pair of connecting plates 4 are connected to the upper side of the base 3 by screws, a semi-circular hole corresponding to the pipeline body 1 is provided in the middle part of the connecting plate 4, a bearing plate 5 is provided on the upper side of the connecting plate 4 by screws, and a detection component is provided between the bearing plate 5 and the base 3.

[0018] The support plate 5 is U-shaped, and a connecting seat 6 is provided on the upper side of the support plate 5. An exhaust fan 7 is provided on the upper side of the connecting seat 6. The four corners of the connecting seat 6 are connected to the upper side of the support plate 5 by screws. A control module 8 is provided on the connecting seat 6, and a wireless signal transmission module 9 is provided on the upper side of the connecting seat 6.

[0019] The detection assembly includes a vertical plate 10, the upper side of which is connected to the lower side of the support plate 5, the lower side of which is in close contact with the upper side of the base 3, and a gas detector 11 is provided on the inner side of the vertical plate 10.

[0020] It should be noted that in the gas pipeline system of old residential areas, the control valve 2 is a key component for controlling the gas supply and demand, and the risk of its location is particularly prominent. Due to long-term use, the control valve 2 itself may experience wear and loosening, resulting in poor sealing and gas leakage. Therefore, it is necessary to perform leak detection on the control valve 2.

[0021] During assembly, the base 3 is first placed under the control valve 2, and then the connecting plate 4 and the bearing plate 5 are assembled with screws. The base 3 is provided with a first reinforcing rib 12, and the bearing plate 5 is provided with a second reinforcing rib 13 on the lower side to maintain the overall stability of the device. The bearing plate 5 is provided with a vertical plate 10 on the lower side, and a gas detector 11 is provided on the inner side of the vertical plate 10 to monitor whether there is a gas leak at the control valve 2 in real time. At the same time, the vertical plate 10 can also provide vertical support for the bearing plate 5, further increasing the stability of the bearing plate 5.

[0022] When the gas detector 11 detects a gas leak, the control module 8 controls the exhaust fan 7 to operate, extracting the leaked gas and quickly discharging it outdoors through the delivery pipe 14. This reduces the indoor gas concentration, preventing gas accumulation and potential danger due to excessive concentration. Simultaneously, the wireless signal transmission module 9 transmits a wireless alarm signal to warn maintenance personnel. Combined with the buzzer alarm 15, this multi-level early warning system effectively reduces the risk of explosions and protects the lives and property of residents.

[0023] The control module 8, the wireless signal transmitting module, the exhaust fan 7, and the buzzer alarm 15 are electrically connected. The connection method and its internal structure are technologies disclosed by those skilled in the art and will not be described in detail.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
