Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen storage, in particular to a safe hydrogen storage device. Background Art

[0002] Hydrogen cylinders are high-pressure containers for storing and transporting nitrogen. They are generally made of alloy structural steel by hot stamping and pressing, and are cylindrical in shape. They are used in hospitals, emergency stations, sanatoriums, food factories, chemical plants, etc. The shoulders of the cylinders are stamped with information such as working pressure, test pressure, volume, weight, etc. The surface is painted green, and the word "hydrogen" is written in red. The standard for the gas storage capacity of hydrogen cylinders is the pressure resistance. The upper limit of the pressure of conventional hydrogen cylinders is 15Mp (megapascals), which is converted to atmospheric pressure, which is 147 atmospheres. The pressure resistance test value is 22.5Mp. The pressure in the conventional filled cylinder should be around 12-15Mp. The gas in the cylinder cannot be completely used up, and a residual pressure of no less than 0.1-0.2MP should be retained.

[0003] When using existing hydrogen cylinders, most of them are directly placed on the ground. Because the hydrogen cylinders are relatively high and the contact area between the bottom of the bottle and the ground is small, it is easy to hit the hydrogen cylinder if you are not careful during use, which may not only easily hit people and cause injuries, but also cause certain damage to the hydrogen cylinder itself, affecting its safe use.

[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 5 As shown, a safe hydrogen storage device provided in this embodiment includes a tank body 1, a gas pipe 5 is welded on the top of the tank body 1, a deflation nozzle 2 is formed on one side of the gas pipe 5, and a charging nozzle 4 is symmetrically formed on the deflation nozzle 2, a valve switch 3 is installed on the top of the gas pipe 5, a clamping ring 6 is clamped and connected at the middle position of the tank body 1, a hinge 8 is welded on one side of the outer wall of the clamping ring 6, a buckle 14 is riveted on one side of the outer wall of the clamping ring 6, a fixing seat 7 is evenly installed on the outer wall of the clamping ring 6, the fixing seat 7 is slidably connected to a first support rod 10, and a second support rod 11 is sleeved inside the first support rod 10.

[0023] A rubber pad 9 is pasted on the inner wall of the clamp ring 6 , and the rubber pad 9 fits the outer wall of the tank body 1 . The rubber pad 9 effectively increases the friction between the clamp ring 6 and the tank body 1 , which is beneficial to the stability of the clamp ring 6 .

[0024] A limit block 17 is welded under the fixing seat 7, and a stop block 16 is arranged on the top of the first support rod 10. The stop block 16 and the limit block 17 are movably fitted together. The first support rod 10 is movably connected to the fixing seat 7 through a pin 15. The limit block 17 and the stop block 16 cooperate with each other. The stop block 16 and the limit block 17 are made of magnetic materials and can be adsorbed to each other, so that the support rod can be folded, which is convenient for users to store.

[0025] A connecting sleeve 21 is provided at the bottom of the first support rod 10, and a cam lever 12 is slidably connected in the connecting sleeve 21. A pressure block 13 is provided below the cam lever 12. A slide groove 19 is formed on one side of the outer wall of the second support rod 11, and the pressure block 13 is located on the slide groove 19. The first support rod 10 is connected with the slide groove 19 on the second support rod 11, thereby realizing free extension and retraction of the second support rod 11, which is convenient for users.

[0026] A support foot 12 is embedded at the top of the second support rod 11, and anti-skid particles 18 are arranged at the bottom of the support foot 12, which improves the friction between the support foot 12 and the ground and makes the support foot 12 more firm.

[0027] The first support rod 10 and the second support rod 11 are made of high-strength plastic, which is conducive to the long-term use of the support rods.

[0028] Working principle of the device: When the device is used, the collar 6 can be placed on a suitable position on the outer wall of the tank body 1, and the rubber pad 9 on the inner wall of the collar 6 contacts the outer wall of the tank body 1. The rubber pad 9 effectively increases the friction between the collar 6 and the tank body 1, which is beneficial to the stability of the collar 6. Then the buckle 14 is pressed, and then the first support rod 10 is pulled up. At this time, the stopper 16 on the first support rod 10 and the limit block 17 on the fixing seat 7 on the outer wall of the collar 6 are adsorbed together by magnetic force. Then, according to the actual situation, the extension and retraction of the second support rod 11 are adjusted to make the support foot 120 contact the ground. Finally, the cam lever 12 is rotated to press the pressing block 13 into the slide groove 19 of the second support rod 11, so that the second support rod 11 is fixed, thereby achieving effective protection of the hydrogen cylinder and avoiding the risk of tipping over. It not only protects the personal safety of the user, but also enhances the safety of the hydrogen cylinder.

[0029] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
