Description

Technical Field

[0001] The present invention relates to an alarm device, in particular to an intelligent alarm device for a gas power plant, belonging to the technical field of gas alarms. Background Art

[0002] Natural gas is generally considered a cleaner fossil fuel than coal and oil because its combustion produces less carbon dioxide and other pollutants. A gas-fired power plant is a power plant that uses natural gas as its main fuel. Its basic working principle is to convert the thermal energy generated by the combustion of natural gas into mechanical energy, and then convert the mechanical energy into electrical energy to generate electricity. Gas-fired power plants are generally characterized by high efficiency, cleanliness, and flexibility.

[0003] Smart gas alarms are a crucial component of information technology services for gas-fired power plants. They primarily utilize sensors for data collection, combined with communications and data analysis technologies, to enable real-time monitoring, early warning, and fault diagnosis of key equipment and systems in gas-fired power plants. This effectively improves the safety and reliability of gas-fired power plants, reduces accidents, and ensures a stable power supply.

[0004] The Chinese patent, entitled "An Alarm Device for Thermal Control of Thermal Power Plants" (publication number CN118747938A), discloses an alarm technology for thermal control of thermal power plants. It utilizes the cooling effect of water circulation to provide cooling protection around smoke alarms and infrared thermometers. At the same time, it can discharge the thick smoke generated by the fire outdoors and spray water to extinguish the fire, preventing high temperature from damaging the smoke alarm. However, when in use, the alarm device can only be used in designated indoor locations and cannot be used for outdoor natural gas pipeline monitoring and alarm. Moreover, the working environment of outdoor natural gas pipelines is more severe than that of indoors, so the risk of leakage is higher, especially at the flange connections of the natural gas pipelines.

[0005] The Chinese patent, entitled "A Gas Power Plant Leakage Monitoring Device and Its Working Method" (Announcement No. CN116659752B), discloses a gas power plant leakage monitoring technology with a simple structure and sophisticated design. It effectively solves the problem of difficulty in detecting gas pipeline leaks in open-air environments and is equipped with a sealing portion that can be sealed in time to prevent continuous leakage from causing safety accidents. However, the installation and use method of the monitoring device is the same as that of a traditional monitoring and alarm device, which can only detect designated locations and cannot perform mobile monitoring and alarm according to the setting of the natural gas pipeline. For this reason, an intelligent alarm device for a gas power plant is proposed. Summary of the Invention

Then, the piston rod of the second electric push rod 305 uses the sleeve 306 and the lower support plate 307 to push the lower pipe clamping rack 303 to reset, so that the elastic sealing gasket 308 is completely covered outside the flange, and the sealing sheet 73 provided can be used to cooperate with the lower pipe clamping rack 303 to seal the two ends of the elastic sealing gasket 308.

[0039] When leakage detection is required at the flange connection, the central control module 602 uses the relay 603 to start the fan 404. The working fan 404 cooperates with the air inlet 403 and the air guide port 405 to inject external air between the elastic sealing gasket 308 and the flange, and then exhausts the air through another air guide port 405 in cooperation with the exhaust port 402 to promote air circulation at the flange connection. Then, the combustible gas concentration in the air is detected by the provided gas detector 401, and the detection data is fed back to the central control module 602 through the wire. When the gas detector 401 detects combustible gas data, the central control module 602 uses the relay 603 to start the sound and light alarm 606, and the working sound and light alarm 606 makes a sound and light alarm, and the central control module 602 cooperates with the communication module 604 to remotely feedback the alarm information and make a remote alarm.

[0040] When the gas detector 401 does not detect combustible gas data, the central control module 602 uses the relay 603 to control the clamping sealing mechanism 3 and the leakage detection mechanism 4 to reset as a whole, and then cooperates with the drive component 5 to drive the intelligent alarm device to continue moving along the direction of the slide rail 103, so as to detect the remaining flange interfaces on the pipeline in turn.

[0041] When the intelligent alarm device moves along the direction of the slide rail 103, the high-definition probe 607 can also be used to capture images of the natural gas pipeline 71, and then the central control module 602 cooperates with the image processing module 605 to use image recognition technology to determine the current position of the intelligent alarm device, so as to more accurately control the intelligent alarm device to move to the flange interface.

[0042] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
