Description

Technical Field

[0001] The utility model relates to the technical field of gas pipelines, in particular to a leakage-proof conveying device for gas supply. Background Art

[0002] Gas is a general term for gaseous fuels, which can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal-to-gas. Among them, natural gas is widely used. As a clean, efficient, and high-quality energy source, it plays an important role in many fields. The pollutants produced when natural gas is burned are relatively small. With the improvement of people's environmental awareness and the improvement of urban infrastructure, the natural gas pipeline network is becoming increasingly popular, and more and more residential communities and rural areas are connected to natural gas pipelines.

[0003] If residents use gas stoves for a long time, the two ends of the natural gas connecting hose may become loose naturally, or the hose may be pulled off or loosened due to improper human operation (such as scrubbing and moving the stove, not installing partitions on pull-out cabinets, etc.). Moreover, the hose used for a long time may become hard and brittle during the aging process, lose its original flexibility, and be prone to breakage, especially when subjected to external forces. After the natural gas leaks, if it encounters flammable sources such as open flames or electric sparks, it may cause fires and explosions. Moreover, natural gas leaks will cause the methane concentration in the air to increase. Long-term breathing of high concentrations of methane may cause discomfort symptoms such as headaches, dizziness, nausea, and even be life-threatening. Utility Model Content

[0007] It also includes a gas collecting tank, the first fixing member is provided with a vent pipe communicating with the chamber, the other end of the vent pipe is connected with the gas collecting tank, and a valve for turning on and off the gas is installed between the vent pipe and the gas collecting tank;

[0008] It also includes a gas alarm, which is arranged between the ventilation pipe and the gas collecting tank to detect gas leakage.

[0009] Furthermore, first mounting ears are fixedly disposed at the upper and lower ends of the first fixing member, second mounting ears are fixedly disposed at the upper and lower ends of the second fixing member, and bolts are installed between the first mounting ears and the second mounting ears.

[0010] Furthermore, a limiting member is provided at one end of one of the first mounting ears extending toward the second mounting ear, a limiting groove is formed between the limiting member and the first mounting ear, and the second mounting ear is plugged into the limiting groove.

[0011] Furthermore, a limiting plate is extended outwardly from one end of the limiting groove, and one of the second mounting ears is in contact with the limiting plate.

[0012] Furthermore, the sealing layer is made of silicone or rubber.

[0013] Furthermore, it also includes a connecting pipe, one end of which is connected to the ventilation pipe, and the other end is connected to the gas collecting tank. The valve includes a first valve body and a second valve body. The first valve body is used to turn on and off the leaked gas in the chamber, and the second valve body is used to turn on and off the gas in the gas collecting tank.

[0014] Furthermore, a plurality of supporting legs are fixedly provided on the lower end surface of the gas collecting tank.

[0015] By adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0016] This solution provides a protective device, a gas alarm and a gas collecting tank. The protective device can tighten the connecting head to improve the air tightness of the first gas pipe and the second gas pipe. When gas leaks at the connecting head of the first gas pipe and the second gas pipe, the leaked gas in the chamber will be transported to the connecting pipe through the ventilation pipe. The gas alarm detects the gas in the connecting pipe and generates an alarm to remind the user of the gas leak. The inside of the gas collecting tank is in a negative pressure state. The connecting pipe transports the gas to the gas collecting tank, which can store the leaked gas. In the event of a gas leak, the leaked gas is collected in the gas collecting tank in time, which can prevent the leaked gas from further spreading and reduce the possibility of accidents. The gas collected in the gas collecting tank can be reused after subsequent treatment, or discharged into the atmosphere in a safe manner, avoiding the problems that may be caused by direct discharge.
