Description

Technical Field

[0001] The utility model relates to the technical field of gas storage equipment, in particular to a strap fixing device for a storage bottle and a gas storage device. Background Art

[0002] Hydrogen energy has become the most promising new green energy with its high energy, renewable and environmentally friendly advantages. However, the backward hydrogen storage technology and the lack of guaranteed safety performance have seriously hindered its large-scale application. After years of development, the storage bottles of hydrogen storage cylinders have been successfully developed from the initial steel cylinders to the current carbon fiber wrapped cylinders, achieving a leap in product structure. Carbon fiber wrapped cylinders have been widely used in the field of vehicle-mounted hydrogen storage due to their light weight, good fatigue resistance and strong carrying capacity. At present, metal liner carbon fiber fully wrapped gas cylinders (hereinafter referred to as "Type III bottles") and non-metal liner carbon fiber fully wrapped gas cylinders (hereinafter referred to as "Type IV bottles") are the main products in the field of vehicle-mounted hydrogen storage. Type III bottle technology has basically matured, and there are many mature products in China.

[0003] Type III cylinders are carbon fiber wrapped gas cylinders. When the pressure inside the cylinder is high or low, the diameter of the cylinder will change due to the elastic strain of the carbon fiber. When the pressure in the cylinder is high, the increased diameter will increase the deformation displacement of the cylinder strap along the length direction, causing the strain of the strap to increase by about 0.5%, which in turn causes the strength of the strap to fail. In the prior art, the strap is connected by a spring, and the tensile preload and deformation displacement of the strap are provided by the spring. However, the spring will increase the weight of the hydrogen storage system and the failure rate. The spring will also increase the difficulty of installation when the preload is corrected during the installation process. Utility Model Content

DETAILED DESCRIPTION

[0033] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1-Figure 4 As shown, the present embodiment provides a storage bottle strap fixing device, comprising: a strap body 100; the strap body 100 is arranged in a ring shape along the outside of the storage bottle 500, and hollow holes 101 are opened along the surface of the strap body 100. The strap body 100 can be deformed through the hollow holes 101 as the diameter of the storage bottle 500 changes, so that the strap body 100 is fitted and fixed to the outer wall of the storage bottle 500.

[0035] It should be noted that the storage bottle binding device provided in the present embodiment can pre-tighten and bind the bottle body of the storage bottle 500. Specifically, the storage bottle 500 can be a hydrogen gas storage bottle or a hydrogen liquid storage bottle. Hydrogen is stored in the hydrogen gas storage bottle or the hydrogen liquid storage bottle. The storage bottle 500 has high-pressure and low-pressure states during the hydrogen storage process. Due to the elastic strain of the carbon fiber, the diameter of the bottle body of the storage bottle 500 will change. In order to adapt to the diameter change of the storage bottle 500, the strap body 100 can be arranged in a ring on the outside of the storage bottle 500, and the strap body 100 is fixed to the outer wall of the storage bottle 500. The storage bottle 500 can be fixed in the hydrogen storage system through the strap body 100. The strap body 100 has a plurality of hollow holes 101 arranged at intervals on the surface, that is, the surface of the strap body 100 has a plurality of reinforcing rib structures, and the strap body 100 can be based on the hollow holes 101 with the reinforcing ribs having a shape When the storage bottle 500 is in a high-pressure state, the strap body 100 can be bound and installed with the storage bottle 500, and the strap body 100 will be deformed to pass the preload force required for the installation of the storage bottle 500. When the storage bottle 500 gradually drops to a low-pressure state, the strap body 100 will retract as the diameter of the storage bottle 500 changes, and at the same time, the installation and fixation of the storage bottle 500 can be ensured; when the strap body 100 can be bound and installed with the storage bottle 500 when the storage bottle 500 is in a low-pressure state, the strap body 100 can be matched with the outside of the storage bottle 500 for installation and fixation. When the storage bottle 500 is gradually inflated to form a high-pressure state, the strap body 100 will expand and deform as the diameter of the storage bottle 500 changes. On the basis of ensuring the installation and fixation of the storage bottle 500, it can also provide a preload force to the storage bottle 500, thereby ensuring the stability of the storage bottle 500.
