Description

Technical Field

[0001] The present application relates to the technical field of fluid storage and transportation, and in particular to a highly sealed carbon fiber tank. Background Art

[0002] Hydrogen storage safety is a core issue throughout all aspects of hydrogen utilization, because hydrogen has dangerous characteristics such as wide combustion limit, low ignition energy, fast flame propagation speed, and hydrogen embrittlement. Once an accidental leak of high-pressure hydrogen occurs, it may cause fire and explosion accidents.

[0003] At present, the existing storage tank structures are mainly divided into single-layer and double-layer structures. Among them, the single-layer structure is more widely used because of its simple manufacturing and low price. The double-layer structure storage tank mainly uses the interlayer (vacuuming or filling materials) to achieve the function of thermal insulation.

[0004] But no matter it is single-layer or double-layer, the structure usually includes the tank body itself and a bracket fixed at the bottom of the tank body to support the tank body. This structure can easily cause a series of problems such as the tank body tipping over and bumping during transportation, thus causing damage to the tank body and posing certain safety hazards. Utility Model Content

[0017] Optionally, two guide rails are fixed on the bottom plate of the protective cover, and the roller is located between the two guide rails.

[0018] By adopting the above technical solution, the track is used to limit the movement direction of the roller, so that the tank body can be moved to an accurate position in the protective cover.

[0020] By adopting the above technical solution, when the tank body is transferred into the protective cover, the staff can turn the hand wheel to make the roller separate from the bottom wall of the protective cover. At this time, the fixed frame supports the tank body, and the roller abuts against the lower end surface of the limit rail to limit the tank body in the vertical direction.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] The protective cover protects the tank as a whole and reduces damage to the tank due to bumps and collisions.

The positioning springs 6 are arranged horizontally, and one end of the positioning spring 6 is fixed to the inner wall of the box body 3, and the other end of the positioning spring 6 is fixed to the positioning plate 5, and pushes the positioning plate 5 to move toward the opening of the box body 3.

[0033] Reference Figure 1 The tank body 1 is welded with an abutting plate 7 at the end of the positioning plate 5, the abutting plate 7 is parallel to the positioning plate 5, and a plurality of positioning protrusions 8 are welded on the abutting plate 7 at the end face of the positioning plate 5. The positioning plate 5 is provided with a plurality of positioning grooves 9, and the positioning protrusions 8 correspond to the positioning grooves 9 one by one. When the tank body 1 is transferred to the box body 3, the positioning plate 5 abuts against the abutting plate 7, and the positioning protrusions 8 are snapped into the positioning grooves 9, and the tank body 1 continues to be pushed to move, the positioning spring 6 is compressed, and the box cover 4 is closed. Under the action of the positioning spring 6, one end of the tank body 1 abuts against the box cover 4. The positioning spring 6 plays a buffering role on the one hand, and on the other hand, it is convenient for the positioning of the tank body 1 and reduces the possibility of the tank body 1 sliding in the box body 3.
