Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a quick-release mechanical piston and its hydrogen compressor. Background Technology

[0002] Hydrogen energy refers to the chemical energy released by the chemical reaction of hydrogen and oxygen. It is a clean secondary energy source with advantages such as high energy density, high calorific value, wide availability, storability, renewability, combustibility (both electric and combustible), zero pollution, and zero carbon emissions. It helps solve energy crises and environmental pollution problems and is hailed as the "ultimate energy" of the 21st century. In hydrogen refueling stations, hydrogen is typically pressurized to increase its storage capacity. Currently, pressurization is mainly performed by mechanical pistons, which reciprocate. As pressurization increases, the piston and cylinder experience friction. Without timely maintenance, the piston and cylinder wear down and become unusable, requiring replacement of either the cylinder or the piston. Existing compressors require assembly replacement when the piston wears out, increasing maintenance costs. Utility Model Content

[0040] Mounting part 3 is disposed inside the movable compression part 1; piston movable housing is disposed on mounting part 3.

[0041] The limiting mechanism 4 is disposed inside the mounting part 3;

[0042] Adjust component 5 and rotate it onto the mounting part 3;

[0043] When the adjusting component 5 drives the limiting mechanism 4 and the fixing component 2 to couple, the moving compression part 1 is fixed on the mounting part 3.

[0044] In this embodiment, the limiting mechanism 4 includes a telescopic component, a driving component, and a limiting groove 4-6. The telescopic component is slidably disposed inside the mounting part 3. The telescopic component is connected to the adjusting component 5 through the driving component disposed inside the mounting part 3. When the telescopic component enters the limiting groove 4-6 disposed inside the movable compression part 1, the movable compression part 1 is fixed on the mounting part 3.

[0045] The drive assembly drives the telescopic assembly to move inside the mounting part 3. With the continuous output of the drive assembly, the telescopic assembly enters the limiting groove 4-6 inside the moving compression part 1, thereby fixing the moving compression part 1 on the mounting part 3.

[0046] In this embodiment, the telescopic component includes a movable block 4-5 slidably disposed inside the mounting portion 3 and a threaded rod 4-3 disposed inside the mounting portion 3. The movable block 4-5 and the threaded rod 4-3 are coupled together, and the threaded rod 4-3 is connected to the drive component.

[0047] The rotation of the threaded rod 4-3 drives the sliding block 4-5 to slide. When the sliding block 4-5 moves into the limiting groove 4-6, the moving compression part 1 is fixed on the mounting part 3.

[0048] In this embodiment, the drive assembly includes a rotating shaft 4-1 and a gear set. The rotating shaft 4-1, which is mounted on the mounting part 3, is connected to the gear set and the threaded rod 4-3.
