Description

Technical Field

[0001] The utility model relates to the technical field of natural gas dispersal, in particular to a vehicle-mounted natural gas lifting and dispersing device. Background Art

[0002] Natural gas is a high-quality, efficient, and clean energy source. It's typically transported long distances using LNG tankers. To prevent excessive pressure in the LNG tankers, these tanks typically require a vent pipe to release the natural gas and reduce the pressure.

[0003] However, LNG tank trucks are subject to driving height restrictions, requiring that the height of the exhaust port of the vent pipe cannot exceed the restricted height. As a result, when the natural gas in the on-board gas tank is released, the low height of the exhaust port can easily lead to natural gas accumulation, posing a risk of fire or explosion. In addition, the exhaust port of the vent pipe is exposed to the air for a long time, which can easily cause dust or rainwater to enter the vent pipe, causing blockage or corrosion inside the vent pipe.

When the screw 4 rotates, it can drive the slide plate 16 threadedly connected to the screw 4 to move, and then the slide plate 16 drives the base plate 2 to move through the slide bar 14.

[0028] The top of the bottom plate 2 is fixedly connected to a discharge pipe 3, and a sealing cover 5 is provided at the exhaust port of the discharge pipe 3. A spring 6 is fixedly connected to the side of the sealing cover 5 away from the discharge pipe 3, and the other end of the spring 6 is fixedly connected to a limit plate 7.

The motor 20 drives the screw 4 to rotate through the coupling 21. When the screw 4 rotates, it can drive the slide 16 threadedly connected to the screw 4 to move, and then the slide 16 drives the bottom plate 2 to slide upward along the sliding hole 13 through the sliding rod 14. The bottom plate 2 will drive the discharge pipe 3 to rise, so that the exhaust port height of the discharge pipe 3 is higher than the restricted height. After the height of the discharge pipe 3 is lifted, the air compressor 9 is started and the valve of the discharge pipe 3 is opened. The air compressor 9 will quickly discharge the natural gas in the vehicle-mounted gas tank into the discharge pipe 3, and the natural gas in the discharge pipe 3 will lift the cover 5 and be discharged; after the discharge is completed, the elastic action of the spring 6 can make the cover 5 close to the exhaust port of the discharge pipe 3 to prevent dust or rainwater from entering the discharge pipe 3.
