Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydrogen storage, in particular to a structural reinforcement device for a hydrogen storage well. Background Art
[0002] Drilling and hole forming are important components of hydrogen storage well manufacturing and installation. The quality of the wellbore directly affects whether the casing process of the hydrogen storage well is smooth and whether the uniformity of the cement ring thickness meets the requirements. It has a vital impact on the production and manufacturing process and subsequent use of the hydrogen storage well. The surface casing must be lowered into the original formation or hard formation with good formation cementation to seal the backfill layer and the soft and easily collapsed formation. The surface casing is fixed with cement after correction to ensure the cementing quality of the surface steel pipe and to ensure that the surface casing does not deviate or settle. Structural reinforcement devices are required.
[0003] After searching, the utility model patent with patent number CN217208921U discloses an anticline structure of a hydrogen storage well reinforcement platform, and specifically discloses a reinforcement component, which includes a pipe sleeve, an upper restriction net, a lower restriction net, a lifting ring rod, a restriction bolt, a first flange and a second flange. The upper restriction net and the lower restriction net are slidingly sleeved at the bottom end of the pipe sleeve near the bottom, and the upper restriction net and the lower restriction net are clamped by the lifting ring rod. The first flange is fixedly arranged at the edge of the top outer wall of the pipe sleeve, and the second flange is threadedly connected to the first flange by the restriction bolt. By combining the graphics and text of the utility model patent, it can be seen that in the utility model patent, if the pipeline descends too fast, it will cause damage to the pipeline, and it is easy to cause dislocation and settlement during use. Therefore, a structural reinforcement device for a hydrogen storage well is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0022] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.
[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.
[0024] A structural reinforcement device for a hydrogen storage well, such as Figure 1 As shown, the nut 306 limits the limiting bolt 305 to prevent the limiting bolt 305 from falling under the flange three 304.
[0025] like Figure 2 As shown, below the flange 2 303 , a feed port is provided on the top of the reinforcement pipe 301 to facilitate pouring cement into the interior of the reinforcement pipe 301 .
[0026] like Figure 3 As shown, the two ends of the eye rod 3010 are bent to ensure that the limiting plate 308 is at a 90-degree angle with the inner pipe 1, thereby preventing the inner pipe 1 from deviating.
[0027] When implementing, follow these steps:
[0028] 1) First, sleeve the limiting plate 1 308 and the limiting plate 2 309 onto the outside of the inner pipe 1, use the eyebolt 3010 to fix the limiting plate 1 308 and the limiting plate 2 309, and use the limiting bolt 305 to fix the flange 2 303, the flange 304, the limiting plate 1 308 and the limiting plate 2 309;
[0029] 2) Then, the inner pipe 1 is placed inside the reinforcement pipe 301 by hoisting. When the inner pipe 1 contacts the reinforcement pipe 301, the damping spring 3012 reduces the buffering by deformation;
[0030] 3) Finally, pour cement from the feed port into the inside of the reinforcement pipe 301 and the outside of the inner pipe 1.
[0031] In summary, the structural reinforcement device of the hydrogen storage well sets a reinforcement structure 3, sleeves the restriction plate 1 308 and the restriction plate 2 309 on the outside of the inner pipe 1, uses a lifting ring rod 3010 to fix the restriction plate 1 308 and the restriction plate 2 309, uses a restriction bolt 305 to fix the flange 2 303, the flange 304, the restriction plate 1 308 and the restriction plate 2 309, and places the inner pipe 1 inside the reinforcement pipe 301 by lifting. When the inner pipe 1 contacts the reinforcement pipe 301, the shock-absorbing spring 3012 reduces the buffer by deformation, and pours cement into the inside of the reinforcement pipe 301 and the outside of the inner pipe 1, thereby solving the problem in the utility model patent with patent number CN217208921U that if the pipeline descends too fast, it will cause damage to the pipeline and it is easy to cause misalignment and settlement during use.
