DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0021] like Figures 1 to 3 As shown, a high-pressure carbon fiber wrapped hydrogen storage bottle portable backpack of the present embodiment comprises a bag body 1 of a rectangular structure, a shoulder strap 2 and a waist belt 3 are arranged in front of the bag body 1, the back of the bag body 1 is open, and three U-shaped gas cylinder bins 11 are arranged on the top of the bag body 1 from left to right, the U-shaped mouth of the gas cylinder bin 11 faces the back of the bag body 1 and is open, a safety belt 4 is arranged in the opening on the back of the bag body 1 to prevent the gas cylinder from tipping over, a gas cylinder bin 2 12 with a semicircular or U-shaped cross-section is arranged on each side of the bag body 1, and at least one tie 5 for fixing the gas cylinder in the gas cylinder bin 2 12 is arranged on the side of the bag body 1 along the height direction.

[0022] This embodiment is mainly used for carrying hydrogen cylinders, and can also be used for carrying other gas cylinders, such as oxygen cylinders. The package 1 of this embodiment is provided with five positions for placing hydrogen cylinders, which can be appropriately increased or decreased according to actual needs. The hydrogen cylinder can be inserted into the two gas cylinder positions from the side or from the top. Of course, according to the structure of the gas cylinder position 1 11 and the gas cylinder position 2 12 of this embodiment, the former is more convenient.

[0023] The bag body 1 is a rigid structure and can be made of a light material such as plastic. The bottom width of the bag body is equal to the thickness of the bag body 1. For ease of use, the shoulder straps 2 and the waist belt 3 are designed from an ergonomic perspective. The shoulder straps 2 include an upper anti-strangulation belt 21 and a lower adjustment belt 22. The anti-strangulation belt 21 is connected to an adjustment buckle 23 that facilitates the flexible connection of the adjustment belt 22. The waist belt 3 includes a belt buckle 31. The belt buckle 31 is clamped with two drawstrings 32 whose other ends are fixed to the bag body 1.

[0024] After the hydrogen cylinders are placed in the first gas cylinder compartment 11 and the second gas cylinder compartment 12, their heights are equal. The depths of the first gas cylinder compartment 11 and the second gas cylinder compartment 12 are greater than 3 / 4 of the height of the hydrogen cylinder body. To prevent the hydrogen cylinders from being scratched by the package body 1, and to better fix the hydrogen cylinders and provide shock absorption during transportation, a first bottom support 111 with a cylindrical structure is provided at the bottom of the first gas cylinder compartment 11, and a second bottom support 121 with a semi-cylindrical structure is provided at the bottom of the second gas cylinder compartment 12. Spherical grooves are provided at the tops of the first bottom support 111 and the second bottom support 121. At least one U-shaped first side cushion 112 is provided along the height direction of the body of the first gas cylinder compartment 11, and at least one second side cushion 122 is provided along the height direction of the body of the second gas cylinder compartment 12. The first bottom support 111, the second bottom support 121, the first side cushion 112 and the second side cushion 122 can be made of rubber or soft plastic.

[0025] The hydrogen cylinder in the second gas cylinder compartment 12 is fixed by the tie strap 5. To facilitate the loosening or tightening of the tie strap 5, a winding post 14 is provided on the side of the package body 1. One end of the tie strap 5 is fixed to the side of the package body 1, and the other end of the tie strap 5 passes around the winding post 14 and is movably connected to the adjustment buckle 23 fixed on the tie strap 5.

[0026] The safety belt 4 can be a non-elastic belt with a movable connection or an elastic belt. When an elastic belt is used, when placing the hydrogen cylinder into the first gas cylinder compartment, pull the safety belt, and the hydrogen cylinder can be pushed into the first gas cylinder compartment 11 from the side. To prevent the hydrogen cylinder from being knocked and collided by external objects, especially the valve body at the hydrogen cylinder mouth, slots 13 reaching the top are provided on both sides of the opening on the back of the package body 1. An η-shaped package cover 6 that seals the back of the package body 1 and shields the top of the gas cylinder is inserted into the slots 13. Further, to prevent the package cover 6 from shaking and colliding with the package body 1, a strip 7 with a "匚"-shaped cross-section is fixed in the slots 13. The strip 7 is made of plastic. The package cover 6 is inserted into the slot of the strip 7, and the gap between the two sides of the package cover 6 and the strip 7 is 0 to 0.3 mm.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention. For the convenience of describing the technical solutions, the front, back, left, right, up, middle, down, etc. directions used are based on the drawings, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
