[0002] The hydrogen energy pipeline is a tubular facility specially used for conveying hydrogen, and plays a key role in the hydrogen energy industry chain. During long-term operation, the hydrogen energy pipeline may have problems such as pipeline corrosion, wear, and aging of sealing elements, which require maintenance personnel to disassemble the pipeline for comprehensive internal inspection, timely detection of hidden dangers, and replacement of damaged parts to ensure safe and stable operation of the pipeline system.

The utility model installs the purification pipe at one end of the hydrogen energy pipeline, rotates the valve body set at one end of the inner wall of the purification pipe, and since the valve body is spherical and has a cavity in the center, rotating the handle makes the valve body rotate in the purification pipe, and the cavity surface is attached to the inner wall of the purification pipe, thereby closing the purification pipe. At this time, open the first exhaust port, inject carbon dioxide from the inlet pipe into the purification pipe, use carbon dioxide to discharge the air in the hydrogen energy pipeline through the first exhaust port, then close the first exhaust port, open the second exhaust port, and inject hydrogen into the pipeline. Since hydrogen is lighter than carbon dioxide, hydrogen floats on the top of the pipeline, causing carbon dioxide to be discharged through the second exhaust port, thereby purifying the hydrogen in the hydrogen energy pipeline.

[0005] The existing hydrogen energy pipeline is inconvenient to support the connection when in use, and the pipeline is prone to excessive deformation at the connection due to its own gravity or other external forces, especially for large-diameter or long-distance hydrogen energy pipelines.

In view of this, we propose a hydrogen energy pipeline convenient to dismount. UTILITY MODEL CONTENTS

[0031] In order to conveniently support the connecting position of the first pipeline 1 and the second pipeline 2, therefore, like Figures 1-4As shown, the support assembly 5 includes two mounting seats 51 arranged on the lower surfaces of the first pipe 1 and the second pipe 2 respectively, and an arc-shaped slot is formed on the top of the mounting seat 51 and is attached to the pipe. The upper surfaces of the first pipe 1 and the second pipe 2 are respectively provided with arc-shaped mounting blocks 52. The mounting seat 51 and the mounting block 52 are fixedly connected by screws. The mounting seat 51 and the mounting block 52 form an annular cavity, and the inner diameter of the annular cavity is adapted to the outer diameter of the pipe. In use, the pipe near the connecting end surface is located in the annular cavity formed by the mounting seat 51 and the mounting block 52. The mounting seat 51 and the mounting block 52 are fixed by screws to support the connecting portion of the first pipe 1 and the second pipe 2, and increase the stability of the connecting portion of the first pipe 1 and the second pipe 2.

[0032] When the pipe to be maintained is disassembled, in order to make the disassembly more convenient, therefore, as shown, Figures 1-4 The base 4 and the support assembly 5 are provided with an adjusting assembly 6. The adjusting assembly 6 includes two groups of scissors arms 61 arranged on the top of the base 4 and the bottom of the mounting seat 51. One group of scissors arms 61 is located inside the other group of scissors arms 61 and is substantially X-shaped when viewed from the side. One group of scissors arms 61 is rotatably arranged on the top of the base 4 and the bottom of the mounting seat 51. The other group of scissors arms 61 is slidably arranged on the top of the base 4 and the bottom of the mounting seat 51. In the initial state, both groups of scissors arms 61 are in a state with a small horizontal included angle. When disassembling the pipe to be maintained, first, the fixing screws between the flanges 3 at the ends of the pipe are disassembled. The inner sides of the two groups of scissors arms 61 are slid inward. The scissors arms 61 are unfolded and raised. The horizontal included angle of the two groups of scissors arms 61 is increased. The mounting seat 51 at the top is moved upward. Then, the mounting seat 51 is moved upward to lift the end of the pipe segment to be disassembled, so that it is separated from the adjacent pipe in close connection. Then, the screws between the mounting seat 51 and the mounting block 52 are disassembled. The pipe to be maintained is removed from the mounting seat 51. The disassembly work is completed. The pipe to be disassembled is lifted and separated from the adjacent pipe, which is convenient and saves physical effort.

[0033] When the scissors arms 61 slide inward, in order to make the sliding more convenient, therefore, as shown, Figures 1-5As shown, the bottom of the mounting seat 51 is connected to the top of the inner group of scissors arms 61 on one side, and a back-shaped mounting frame 62 is arranged on the side.

When it is needed to make the scissors arms 61 slide, a handle fixedly connected with the input end of the lead screw 63 is rotated to drive the lead screw 63 to rotate, so that the moving block 64 moves inward along the thread structure on the surface of the lead screw 63, and then the moving block 64 drives the inner group of scissors arms 61 rotatably connected with the two sides thereof to slide inward, so that the scissors arms 61 are unfolded and rise, and the mounting seat 51 at the top is driven to move upward. Conversely, when the lead screw 63 is reversely rotated, the moving block 64 is driven to move outward, and then the moving block 64 drives the scissors arms 61 to move outward. At this time, the horizontal included angle between the two groups of scissors arms 61 gradually decreases, the height of the scissors arms 61 decreases, and the mounting seat 51 is driven to descend. The sliding of the scissors arms 61 is conveniently controlled, the height of the mounting seat 51 is conveniently adjusted, and it is beneficial to subsequent disassembly of the pipeline.

[0034] When the scissors arms 61 slide, in order to make them slide more smoothly, therefore, as shown, Figures 1-5 The top of the base 4 is provided with a sliding block 65, the two sides of the sliding block 65 are rotatably connected with the bottom of the inner group of scissors arms 61 on one side, and the surface of the base 4 is provided with a sliding groove 41 matched with the sliding block 65. When the scissors arms 61 slide, the handle is rotated to drive the lead screw 63 to rotate, so that the moving block 64 moves inward along the thread structure on the surface of the lead screw 63, and then the moving block 64 drives the top of the inner group of scissors arms 61 rotatably connected with the two sides thereof to slide inward. At this time, the bottom of the scissors arms 61 slides inward in the sliding groove 41 on the surface of the base 4 through the bottom structure of the sliding block 65, so that the bottom of the scissors arms 61 slides inward, and the scissors arms 61 are unfolded and rise. Conversely, when the lead screw 63 is reversely rotated, the moving block 64 is driven to move outward, and then the moving block 64 drives the top of the scissors arms 61 to move outward. At this time, the bottom of the scissors arms 61 slides inward in the sliding groove 41 on the surface of the base 4 through the bottom structure of the sliding block 65. By making the scissors arms 61 slide smoothly, subsequent disassembly of the pipeline is facilitated.

[0035] The utility model discloses hydrogen energy pipeline convenient to disassemble is in specific use, first pipeline 1, second pipeline 2 are fixedly connected through flange 3, and the surface of pipeline close to the connecting end is located in the annular cavity formed by mounting seat 51 and mounting block 52, and mounting seat 51 and mounting block 52 are fixed through screw, support and reinforce the connecting place of first pipeline 1, second pipeline 2, when disassembling the pipeline that needs to overhaul and maintain, first, the fixing screw between pipeline end flange 3 is disassembled, then rotates the handle fixedly connected with the input end of screw rod 63, drives screw rod 63 to rotate, makes moving block 64 along the thread structure on the surface of screw rod 63 and moves inward, then moving block 64 drives the group of scissor arms 61 rotationally connected with its both sides and slides inward, and scissor arms 61 expand and rise, drive mounting seat 51 on the top and move upward, then when mounting seat 51 moves up, the end of the pipeline section that needs to disassemble is lifted, makes it separate with the adjacent pipeline that is closely connected, then the screw between mounting seat 51 and mounting block 52 is disassembled, and the pipeline that needs to maintain is taken off from mounting seat 51, and the disassembly work is completed.
