However, the bottom of the existing high-pressure gas cylinder is a protruding ring with a certain height, and the protruding ring is welded at the bottom of the gas cylinder by a steel ring or is integrally formed with the bottom of the gas cylinder. Therefore, the existing high-pressure gas cylinder can rock when being unbalanced (if the road jolts and can rock when transporting, or the high-pressure gas cylinder used outdoors also can rock when meeting strong wind), and the situation of dumping easily occurs when the high-pressure gas cylinder rocks greatly, so that the high-pressure gas cylinder capable of self-balancing is needed, and the self-balancing is realized in the environment that the high-pressure gas cylinder is easily unbalanced.

Detailed Description

The technical solutions in the embodiments shown in the present application will be clearly and completely described below with reference to the drawings in the embodiments shown in the present application.

Referring to fig. 1 to 3, a self-balancing high pressure gas cylinder includes a cylinder body 1, a bracket 2, a fixing plate 3, a base 4, a balancing system 5 and a hydraulic system 6; one end of the bracket 2 is connected with the bottle body 1, and the other end of the bracket 2 is connected with the fixing plate 3; the base 4 comprises a body 41 and a support plate 42; the balance system 5 comprises a spring 51, a shock absorber 52, a hydraulic ejector pin 53, a spherical hinge 54 and a support table 55, the spring 51 is sleeved outside the shock absorber 52, one end of the shock absorber 52 is connected with the spherical hinge 54, the other end of the shock absorber 52 is connected with the hydraulic ejector pin 53, the spherical hinge 54 is connected with the support table 55, the hydraulic system 6 comprises an oil pipe and a hydraulic ejector rod 61, and the hydraulic ejector pin 53 is used for ejecting hydraulic oil in the oil pipe; the fixing plate 3 is provided with a first bolt hole 31, the supporting plate 42 is provided with a second bolt hole 421 and a balance pressure hole 422, the fixing plate 3 and the base 4 are connected with the second bolt hole 421 through the first bolt hole 31, the supporting platform 55 is located in the balance pressure hole 422, and the hydraulic ejector rod 61 is connected to the bracket 2;

when the bottle body 1 is inclined, one side of the bottle body 1 can press the support 2 downwards, so that the support table 55 below the support 2 moves downwards, the extrusion shock absorber 52 enables the hydraulic thimble 53 to extrude hydraulic oil in an oil pipe, the hydraulic ejector rod 61 moves upwards, and the support 2 is enabled to restore to be balanced.

The length of the fixed plate 3 is the same as that of the support plate 42, and the fixed plate 3 and the support plate 42 are located between the hydraulic push rods 61 on both sides. The balance pressure holes 422 are formed at both ends of the supporting plate 42, so that the hydraulic thimble 53 can extrude hydraulic oil in the oil pipe even if the bottle body 1 slightly shakes, thereby more effectively restoring the balance of the bottle body 1

The spring 51 has a greater damping than the damper 52. The large-damping spring 51 can support the fixing plate 3 and the supporting plate 42, and the large-damping spring 51 can effectively inhibit slight shaking of the bottle body 1, so that frequent work of the hydraulic system 6 is avoided, and the service life of the self-balancing high-pressure gas cylinder can be prolonged.

A rubber pad is also arranged between the fixed plate 3 and the supporting plate 42. The rubber pad can prevent slight rocking of bottle 1, guarantees that better keep balance state that bottle 1 can be quick.

The hydraulic ram 61 is extended to a length just to make the bottle body 1 horizontal. According to the hydraulic principle, because the hydraulic oil in the oil pipe can be squeezed out by the small force of the hydraulic ejector pin 53, if the hydraulic ejector rod 61 extends too long, the balance of the bottle body 1 can be influenced, so that in order to prevent the situation, the bottle body 1 is just in the horizontal state by the extending length of the hydraulic ejector rod 61, and the bottle body 1 can be quickly restored to the balance state.

Therefore, when the self-balancing high-pressure gas cylinder of the application is in an unbalanced state, the inclination state of the cylinder body 1 can be adjusted through the balance system 5 and the hydraulic system 6, so that the self-balancing of the high-pressure gas cylinder is realized.
