AI Technical Summary
Due to the fixed settings of the existing fire-fighting and water supply and drainage devices in natural gas pipelines, they cannot effectively cool down the whole of the long pipeline, resulting in the need to design multiple fire-fighting devices to increase fire-fighting costs.
A natural gas pipeline fire-fighting water supply and drainage device is designed, including a water collection shell and a gas pipe body. The water collection shell is arranged on the lower side of the gas pipe body. The bottom of the gas pipe body is equipped with a T-shaped slide chute and a temperature sensing controller. The temperature sensing controller is connected to the water pump, and the water pump pumps water into the spray pipe. The spray pipe drives the transmission mechanism to make the device move back and forth on the surface of the gas pipe body.
This device can not only cool the upper side of the gas pipe body, but also collect spray water through the water collection shell to soak the lower side in water, which improves the overall cooling effect, reduces the number of fire-fighting devices, and reduces the fire-fighting cost.
