Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-Figure 5 As shown, the present invention provides a support structure of a liquid hydrogen spherical tank and a liquid hydrogen spherical tank, comprising a base plate 1 and a liquid hydrogen spherical tank shell 2, an annular shell 3 is fixedly connected to the top of the base plate 1, rectangular through holes 4 distributed in an annular array and connected to the inside of the annular shell 3 are provided on the top of the annular shell 3, and slide grooves 5 distributed in an annular array and adapted to the rectangular through holes 4 are provided on the inner cavity bottom wall of the annular shell 3, an adjusting component 6 rotatably connected to the annular shell 3 is provided inside the annular shell 3, sliders 7 are slidably connected inside the slide grooves 5, and support rods 8 passing through the adjusting component 6 and the rectangular through holes 4 and extending to the top of the annular shell 3 are fixedly connected to the top of the sliders 7, a rectangular shell 9 connected to the left side of the annular shell 3 is fixedly connected, a driving component 10 extending into the inside of the rectangular shell 9 and meshing with the adjusting component 6 is provided on the rear side of the rectangular shell 9, and a reinforcement component 11 is provided between adjacent support rods 8;

[0027] The tops of the support rods 8 are fixedly connected to the insertion rods 12, the outer side of the liquid hydrogen spherical tank shell 2 is fixedly connected to the socket sleeves 13 which are distributed in a circular array at its equator and are compatible with the insertion rods 12, the inner wall of the liquid hydrogen spherical tank shell 2 is fixedly connected to a plurality of support blocks 15, the opposite end of the support block 15 is fixedly connected to the same liquid hydrogen spherical tank liner 16, the outer side of the liquid hydrogen spherical tank liner 16 is fixedly connected to a polyamide shell 17, the top of the liquid hydrogen spherical tank liner 16 is fixedly connected to a bellows 18 which is fixedly connected to the liquid hydrogen spherical tank shell 2 and extends to the top of the liquid hydrogen spherical tank shell 2, the top of the bellows 18 is provided with a tank sealing flange 19 which is compatible with it, and the outer side of the liquid hydrogen spherical tank shell 2 is fixedly connected to a vacuum suction valve 20 which is connected to the interior thereof.

[0028] The liquid hydrogen spherical tank and supporting structure are transported to the installation site and fixedly connected to the ground. The adjusting component 6 is driven to rotate by the driving component 10, and then the support rod 8 moves to the opposite side in the corresponding rectangular through hole 4. At the same time, the slider 7 slides to the opposite side in the corresponding slide groove 5, and the reinforcement component 11 moves on the outside of the support rod 8 until the spacing between the insertion rods 12 at the top of the support rod 8 is adapted to the spacing between the sockets 13 on the outside of the liquid hydrogen spherical tank shell 2. The reinforcement component 11 is fastened to the support rod 8, and the liquid can be loaded. The hydrogen spherical tank shell 2 is hoisted above the center of the base plate 1. The liquid hydrogen spherical tank shell 2 is slowly lowered so that the sockets 13 are all sleeved on the outside of the insertion rod 12, and the installation of the liquid hydrogen spherical tank shell 2 and its supporting structure can be completed. The space between the liquid hydrogen spherical tank shell 2 and the liquid hydrogen spherical tank liner 16 is evacuated to a vacuum state through the vacuum suction valve 20 to block heat transfer, and the polyamide shell 17 can withstand negative pressure and has heat insulation, thereby strengthening the blocking of heat transfer, and having the advantages of convenient installation of the liquid hydrogen spherical tank and its supporting structure, reducing the gasification rate of liquid hydrogen, and improving safety.

[0029] The adjusting assembly 6 includes a worm wheel plate 601 and an arc-shaped hole 602. The inner cavity side wall of the annular housing 3 is rotatably connected with the worm wheel plate 601. The surface of the worm wheel plate 601 is provided with arc-shaped holes 602 distributed in an annular array and adapted to the slide groove 5. The top of the slider 7 is fixedly connected with a support rod 8 that passes through the arc-shaped hole 602 and the rectangular through hole 4 and extends to the top of the annular housing 3.

[0030] The driving assembly 10 includes a motor 101 and a worm 102 . The motor 101 is fixedly connected to the rear side of the rectangular shell 9 . The output end of the motor 101 is fixedly connected to the worm 102 which extends into the rectangular shell 9 and meshes with the worm wheel plate 601 .

[0031] The motor 101 drives the worm 102 to rotate. Since the worm 102 is meshed with the worm gear plate 601, it drives the worm gear plate 601 to rotate inside the annular shell 3, thereby driving the arc hole 602 to rotate. Since the slider 7 at the bottom of the support rod 8 is slidably connected with the slide groove 5, the rotation of the arc hole 602 drives the support rod 8 to move toward the opposite side in the corresponding rectangular through hole 4. At the same time, the slider 7 slides in the corresponding slide groove 5 to the opposite side until the spacing between the insertion rods 12 at the top of the support rod 8 is adapted to the spacing between the sockets 13 on the outer side of the liquid hydrogen spherical tank shell 2.

[0032] The reinforcement assembly 11 includes an upper sleeve 111, a lower sleeve 112, a connecting rod 113 and a fastening bolt 114. The outer side of the support rod 8 is rotatably connected to the upper sleeve 111, and the outer side of the support rod 8 is movably connected to the lower sleeve 112 located below the upper sleeve 111. The adjacent upper sleeves 111 and lower sleeves 112 are movably connected with connecting rods 113, and the connecting rods 113 on the same side are hinged to each other. The outer side of the lower sleeve 112 is threadedly connected to a fastening bolt 114 extending therein.

[0033] During the movement of the support rod 8 to the opposite side, the connecting rod 113 drives the upper sleeve 111 to rotate on the outside of the support rod 8. At the same time, driven by the connecting rod 113, the lower sleeve 112 rotates on the outside of the support rod 8 and moves toward the upper sleeve 111 until the spacing between the insertion rods 12 at the top of the support rod 8 matches the spacing between the sockets 13 on the outside of the liquid hydrogen spherical tank shell 2. By rotating the fastening bolts 114 to make the fastening bolts 114 fit tightly against the outside of the support rod 8, the reinforcement between the support rods 8 can be completed.

[0034] The top edge of the substrate 1 is provided with circular holes 14 distributed in a ring array.

[0035] The circular hole 14 on the top of the base plate 1 is convenient for anchoring the device to the ground surface by bolts.

[0036] Working principle:

[0037] The first step: transport the device to the installation site, pass the bolts through the circular holes 14 to anchor the device to the ground, and drive the worm 102 to rotate through the motor 101. Since the worm 102 is meshed with the worm wheel plate 601, the worm wheel plate 601 is driven to rotate inside the annular shell 3, thereby driving the arc hole 602 to rotate. Since the slider 7 at the bottom of the support rod 8 is slidably connected with the slide groove 5, the rotation of the arc hole 602 drives the support rod 8 to move to the opposite side in the corresponding rectangular through hole 4. At the same time, the slider 7 slides in the corresponding slide groove 5 to the opposite side until the spacing between the insertion rods 12 at the top of the support rod 8 is adapted to the spacing between the sockets 13 on the outer side of the liquid hydrogen spherical tank shell 2;

[0038] Step 2: During the process of the first step, the connecting rod 113 drives the upper sleeve 111 to rotate on the outside of the support rod 8. At the same time, driven by the connecting rod 113, the lower sleeve 112 rotates on the outside of the support rod 8 and moves toward the upper sleeve 111 until the spacing between the insertion rods 12 at the top of the support rod 8 matches the spacing between the sockets 13 on the outside of the liquid hydrogen spherical tank shell 2. By rotating the fastening bolts 114, the fastening bolts 114 are tightly fitted with the outside of the support rods 8, and the reinforcement between the support rods 8 can be completed;

[0039] Step 3: hoist the liquid hydrogen spherical tank shell 2 above the center of the base plate 1, and slowly lower the liquid hydrogen spherical tank shell 2 so that the sockets 13 are all sleeved on the outside of the insertion rod 12, and the installation of the liquid hydrogen spherical tank shell 2 and its supporting structure can be completed. The space between the liquid hydrogen spherical tank shell 2 and the liquid hydrogen spherical tank liner 16 is evacuated to a vacuum state through the vacuum suction valve 20 to block heat transfer, and the polyamide shell 17 can withstand negative pressure and has heat insulation, thereby strengthening the blocking of heat transfer, reducing the gasification rate of liquid hydrogen, and improving safety.
