Problems solved by technology

[0003] When the filling hose is in use, if there are catastrophic failures such as separation of the joint from the pipe body, serious damage to the pipe body, or excessive extension of the pipe body, the hose is likely to shake violently due to the continuous filling of hydrogen, causing property damage. losses, even casualties

Embodiment approach

[0039]Embodiment: In the use of the present invention, when a catastrophic failure occurs such as the separation of the joint 2 from the pipe body 1, the severe damage of the pipe body 1 or the excessive extension of the pipe body 1, the pipe body 1 will continue due to the high-pressure hydrogen being ejected through the crack. Swing violently, and then make the wire rope 58 taut or swing, when the pulling force of the wire rope 58 is greater than the magnetic force between the outer magnetic rod 54 and the inner magnetic rod 55, the inner magnetic rod 55 begins to move in the direction of the pipe body 1, thereby making the blockage The plate 57 moves in the direction of the pipe body 1 until the second side plate 573 contacts the second inclined surface 43. At this time, the circulation channel between the joint 2 and the pipe body 1 is blocked by the blocking plate 57, and hydrogen cannot enter the pipe body. 1 inside, thereby preventing the tube body 1 from shaking violent...

Abstract

The invention discloses an automatic protection type high-pressure hydrogen filling hose structure and a protection method thereof.The automatic protection type high-pressure hydrogen filling hose structure comprises a hose body, connectors arranged at the two ends of the hose body and hoops used for connecting the hose body and the connectors, clamping grooves are formed in the inner walls of the connectors, and protection mechanisms are arranged in the connectors; the two protection mechanisms each comprise an annular disc connected with the inner wall of the connector, a supporting ring is arranged in each annular disc, connecting rods connected with the inner wall of each annular disc are connected to the top and the bottom of each supporting ring, an outer magnetic rod is connected to the interior of each supporting ring, and an inner magnetic rod is connected to the interior of each outer magnetic rod. Through tightening or swinging of the steel wire rope, the plugging plate moves towards the pipe body, so that a second side plate is fully attached to a second inclined plane to cut off a hydrogen circulation channel, hydrogen is prevented from continuously entering the pipe body, the pipe body is prevented from violently swinging due to the impact force of hydrogen, property loss is avoided, and the service life of the pipe body is prolonged. And even casualties can be prevented.

Description

technical field [0001] The invention relates to the technical field of filling hoses, in particular to an automatic protection type high-pressure hydrogen filling hose structure and a protection method thereof. Background technique [0002] Hydrogen is a kind of clean energy. It burns to generate water and does not produce any pollutants. Its transportation mainly includes the transportation of compressed hydrogen, the transportation of liquid hydrogen, the transportation of hydrogen storage medium, the transportation of pipelines and the transportation of manufacturing raw materials. Previously, it needed to be filled in a hydrogen cylinder with a filling hose to facilitate transportation. [0003] When the filling hose is in use, if there is a catastrophic failure such as the separation of the joint from the tube body, the serious damage of the tube body, or the excessive extension of the tube body, the hose may be violently shaken due to the continuous filling of hydrogen...
