[0019] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments. However, it should be understood that the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent; in order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted; the positional relationship described in the drawings is only used for illustrative purposes and cannot be understood as limitations on this patent.

[0020] As an embodiment of the present invention, see the attached Figure 1-5The present embodiment provides a fixing device for a marine hydrogen energy storage tank, comprising a shockproof ring 1 and a clamping ring 2. The edges of both sides of the shockproof ring 1 are constructed with protruding structures 3. The clamping ring 2 is restricted on the upper side of the shockproof ring 1 by the two protruding structures 3. Two connecting ends 4 are constructed on the clamping ring 2. A connecting portion 5 is provided at the two connecting ends 4. The two connecting portions 5 are detachably connected by bolts 6. When the two connecting portions 5 are connected, the shockproof ring 1 and the clamping ring 2 are in the form of a circular ring.

[0021] In the above embodiment, in order to obtain better weather resistance on the basis of providing shockproof effect, the shockproof ring 1 in this embodiment is integrally formed of rubber material. According to the description of the utility model, it should be understood that the shockproof ring of the utility model can also be made of other materials to provide a certain degree of deformation.

[0022] In other preferred embodiments, in order to provide sufficient connection rigidity and obtain certain installation characteristics, the clamping ring 2 in this embodiment is made of metal, such as stainless steel.

[0023] When using the present utility model, Figure 1 As shown, the clamping ring 2 is pressed against the outside of the shockproof ring 1, and then the clamping ring 2 is connected to the mounting frame B. The hydrogen energy storage tank is placed in the shockproof ring 1, and then the clamping ring 2 is clamped against the outer wall of the hydrogen energy storage tank, and the connecting parts are connected using bolts 6.

[0024] After the connection, during the service and voyage of the hydrogen-powered ship, even if slight vibrations and shaking occur when berthing, on the one hand, the shock-absorbing ring provides slight lateral, vertical or circumferential displacements, and on the other hand, a certain degree of slight deformation can be provided through the connection between the connecting part and the bolt. On the basis of ensuring the connection strength, the hydrogen energy storage tank is allowed to undergo necessary slight displacements in multiple directions including lateral, vertical, circumferential, etc. due to vibration during the service and operation of the hydrogen-powered ship, without causing unexpected safety risks.

[0025] In some other preferred embodiments, see the attached Figure 5 The connecting portion 5 includes a connecting column 7, on which a connecting plane 8 is constructed, and the bolt connection 6 is on the connecting plane 8. The connecting column 7 in this embodiment can withstand a large tensile force and is also convenient for bolt tightening and adjustment.

[0026] In some preferred embodiments, based on the above embodiments, the clamping ring 2 is connected to the upper side of the connecting column 7. In this embodiment, since the end of the clamping ring 2 is not connected to the geometric center and the center of gravity of the connecting column 7, when the hydrogen energy storage tank is displaced, in addition to the shock-absorbing ring 1 providing a certain deformation space, the connection method in this embodiment also allows a certain angle of deflection between the connecting column 7 and the clamping ring 2, thereby further providing deformation space.

[0027] In other preferred embodiments, based on the above embodiments, refer to the attached Figure 4 The connecting portion 5 is fixedly connected to the clamping ring 2. The clamping ring 2 is provided with an opening 9 near the connecting portion 5. The opening 9 is used for connecting the bolt 6 to the connecting portion 5. The opening 9 in this embodiment is for facilitating the leveling and adjustment of the bolt 6.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
