[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0022] like Figure 1-Figure 4 As shown, the present embodiment provides a high-pressure hydrogen storage tank that is easy to transport stably, including a hydrogen storage tank 7, two groups of supports 1 are symmetrically welded at the upper and lower ends of one side wall of the hydrogen storage tank 7, a bidirectional screw 8 is installed between the supports 1, one end of the bidirectional screw 8 is connected to a knob 9, two groups of screw blocks 10 are symmetrically sleeved on the bidirectional screw 8, a linkage rod 6 is installed on one side wall of the screw block 10, one end of the linkage rod 6 is connected to a bearing seat 14, a connecting stud 13 is fixed on one side wall of the bearing seat 14, a locking ring 2 is provided on one side of the bearing seat 14, a fixing plate 3 is provided on one side of the locking ring 2, fixing studs 11 are welded on the fixing plate 3 and the back wall of the locking ring 2, and nuts 12 are screwed on the fixing studs 11.

[0023] The bidirectional screw 8 is rotatably installed between the supports 1, and the knob 9 is welded to one end of the bidirectional screw 8 through the support 1. The surface of the knob 9 is frosted and anti-slip. The knob 9 can drive the bidirectional screw 8 to rotate, thereby causing the screw block 10 to move under the action of the thread.

[0024] The two ends of the linkage rod 6 are respectively hinged to the screw block 10 and the bearing seat 14. The bearing seat 14 is a U-shaped structure. When the screw block 10 moves, the linkage rod 6 rotates to push the locking ring 2 on the bearing seat 14 to move.

[0025] The connecting studs 13 are welded on the bearing seat 14 , and the fixing studs 11 are welded on the locking ring 2 and the fixing plate 3 . The connecting studs 13 and the fixing studs 11 can realize the connection between the fixing plate 3 and the locking ring 2 and the bearing seat 14 .

[0026] The nut 12 is connected to the connecting stud 13 and the fixing stud 11 by threads. The connecting stud 13 and the fixing stud 11 have the same threads on their surfaces. The fixing stud 11 is docked with the connecting stud 13, and the nut 12 is rotated so that half of it is on the connecting stud 13 and the other half is on the fixing stud 11, so that the locking ring 2 and the fixing plate 3 can be connected to the bearing seat 14.

[0027] The inner diameter of the locking ring 2 is consistent with the outer diameter of the hydrogen storage tank 7. Four groups of fixing holes 4 are arranged in an array along the length direction of the fixing plate 3. The locking ring 2 can lock and limit the hydrogen storage tank 7. The fixing plate 3 can form a conflict with the side door of the car, and the through hole facilitates further fixing of it with a strap.

[0028] A valve 5 is installed at the top of the hydrogen storage tank 7 , and the valve 5 is a manual valve 5 , which controls the on and off of the hydrogen storage tank 7 .

[0029] The working principle of this device is as follows: during the transportation of the hydrogen storage tank 7, it is placed in the carriage. During the placement process, the two-way screw 8 is driven to rotate by the knob 9, so that the screw block 10 moves under the action of the thread, and the linkage rod 6 rotates accordingly to push the locking ring 2 on the bearing seat 14 to move, and the gas tanks are locked and connected through the locking ring 2, so that the hydrogen storage tank 7 forms a whole. At the same time, the hydrogen storage tank 7 located at the side door of the carriage can replace the locking ring 2 with a fixing plate 3 through a quick connection mechanism, so that the fixing stud 11 and the connecting stud 13 are docked, and the nut 12 is rotated so that half of it is on the connecting stud 13 and the other half is on the fixing stud 11, so that the fixing plate 3 and the bearing seat 14 can be connected. The fixing plate 3 can form a conflict with the side door of the carriage, and the through hole is convenient for the strap to be further fixed, which can effectively improve its stability during transportation and ensure its smooth and safe transportation.
