Description

Technical Field

[0001] The utility model relates to the technical field of gas cylinders, in particular to a gas storage cylinder with high pressure resistance. Background Art

[0002] With the widespread use of gas energy today, gas storage tanks with high pressure resistance have become key equipment to ensure the safe storage and transportation of gas. With the continuous growth of gas demand and the diversification of application scenarios, the performance requirements for gas storage tanks are also increasing. Especially in the fields of industrial production, urban gas supply, and transportation, reliable gas storage tanks are crucial to ensure the stable supply and safe use of energy. Such gas storage tanks need to withstand the pressure of the internal high-pressure gas under different environmental conditions, and at the same time, they must have good impact resistance and easy transportation.

[0003] Existing gas storage tanks generally adopt a more traditional structural design. The tank body is generally made of single or multiple layers of metal materials, connected together through processes such as welding. In terms of pressure resistance, the strength and thickness of the tank body itself are mainly relied on to withstand the pressure of the internal gas. Some gas storage tanks may be equipped with simple reinforcement ribs or support structures on the outside of the tank body to increase the overall strength of the tank body.

[0004] However, traditional gas storage tanks have obvious shortcomings when dealing with internal high-pressure gas. Due to the lack of an effective buffer structure, when the gas in the tank is in a high-pressure state, the internal pressure directly acts on the tank body, which can easily cause fatigue damage to the tank body during long-term use. It may even cause the tank body to rupture when the pressure fluctuates greatly, thereby causing dangerous internal gas leakage, seriously threatening the surrounding environment and personnel safety. Therefore, a gas storage tank with high pressure resistance is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a gas storage tank with high pressure resistance, including a tank shell 1, the bottom of the inner wall of the tank shell 1 is fixedly connected to a support block 14, the top of the support block 14 is fixedly connected to the tank shell 2 5, the tank shell 2 5 is usually made of high-strength alloy material, this alloy has extremely high strength and toughness after a special heat treatment process, and can withstand the huge pressure brought by the internal gas, the outer wall of the tank shell 2 5 is fixedly connected to a plurality of fixed blocks 1 6, the interior of the fixed blocks 1 6 are all rotatably connected to a rotating shaft 1 7, the outer wall of the rotating shaft 1 7 are all fixedly connected to a connecting rod 8, the connecting rod 8 is made of solid steel and has good rigidity and bending resistance, the interior of the connecting rod 8 is fixedly connected to a rotating shaft 2 9, the outer wall of the rotating shaft 2 9 is all rotatably connected to a slider 10, and a spring 11 is fixedly connected between the sliders 10 on both sides, and the spring 11 is made of high-quality The spring steel is made of spring steel and has a good elastic coefficient and fatigue life after a special winding process. The inner wall of the spring 11 is provided with an arc-shaped slide 12. The arc-shaped slide 12 is usually made of stainless steel and has good corrosion resistance and a certain elastic deformation ability. The arc-shaped slide 12 is slidably connected to the inside of the slider 10. The slider 10 is generally made of wear-resistant engineering plastic. Its surface is smooth and the friction between it and the outer wall of the arc-shaped slide 12 is small, which facilitates smooth sliding on the arc-shaped slide 12. The outer wall of the arc-shaped slide 12 is fixedly connected with a plurality of fixed blocks 2 13. The fixed blocks 2 13 are fixedly connected to the inner wall of the tank shell 1. The top of the tank shell 2 5 is fixedly connected with a valve 3. The valve 3 is fixedly connected to the inside of the tank shell 1. A moving component is provided at the bottom of the tank shell 1. The moving component is used to move the equipment. The top of the tank shell 1 is fixedly connected with a handle 2.

[0034] Specifically, during the pressure resistance process of the equipment, when the gas stored inside the equipment is in a high-pressure state, the strong pressure generated by the gas will first squeeze the tank shell 25. At this time, the fixed block 16 connected to the tank shell 25 will transmit the pressure to the connecting rod 8, and the connecting rod 8 rotates with the rotating shaft 17 as the center of the circle. While rotating, the connecting rod 8 will drive the slider 10 to slide on the outer wall of the arc-shaped slide 12 through the rotating shaft 29, and in this process, the slider 10 will drive the spring 11 to be squeezed, and the rebound characteristics of the spring 11 will be used to alleviate and absorb the impact force of the internal pressure of the equipment. When the gas pressure acts on the tank, the spring 11 can respond quickly, absorb part of the pressure through compression deformation, and then gradually release energy when the pressure fluctuation decreases, playing a buffering role, enhancing the pressure resistance of the equipment, and enabling the equipment to operate safely and stably in a high-pressure gas environment.

[0035] Reference Figure 4-Figure 5 The moving assembly includes wheels 17 and a base 4. The wheels 17 are arranged at the bottom of the tank shell 1, and the tank shell 1 is fixedly connected to the top of the base 4. Slots 18 are provided on both sides of the base 4. The inner wall size of the slot 18 matches the card column 21 to ensure that the card column 21 can be stably fixed in the slot 18. Telescopic columns 23 are fixedly connected to the inside of both sides of the base 4. The telescopic columns 23 are generally made of high-strength stainless steel with a smooth surface, which can maintain stability during contraction and extension. The outer walls of the telescopic columns 23 are fixedly connected with springs 22. Springs 22 are generally made of high-quality spring steel and have good elasticity and fatigue life after a special heat treatment process. The output ends of the telescopic columns 23 are fixedly connected with sleeves 20. The sleeves 20 are usually made of stainless steel with a smooth inner wall, which can allow the connecting column 19 to move smoothly therein. The springs 22 are fixedly connected The outer wall of the sleeve 20 and the inner wall of the sleeve 20 are both slidably connected with a connecting column 19. The connecting column 19 is generally made of high-strength metal material, such as aluminum alloy. This material has sufficient strength to withstand tension and is relatively light and easy to operate. The outer wall of the connecting column 19 is fixedly connected with a clamping column 21, and the outer wall of the connecting column 19 is fixedly connected with a connecting block 16. One end of the connecting column 19 is fixedly connected with a handle 15. The handle 15 is usually made of a sturdy and durable plastic material with certain anti-slip properties. The surface may be designed with anti-slip grooves or rubber coating so that the operator can better apply force during the pulling process. The connecting blocks 16 are fixedly connected to the top of the wheel 17. The wheel 17 usually adopts a combination of rubber tires and metal hubs. The rubber tires have good elasticity and shock absorption properties, which can reduce the impact of vibration on the equipment during transportation. The wheel 17 is set at the bottom of the base 4.

[0036] Specifically, during the equipment transportation process, the operator first holds the handle 15 and pulls it upward with force. When the handle 15 is pulled upward, the connecting column 19 drives the card column 21 to move out from the inner wall of the card slot 18. Then the operator continues to pull the handle 15 outward, thereby driving the card column 21 to completely move out from the inside of the base 4. At this time, due to the rebound force of the spring 22, the connecting column 19 is driven downward through the sleeve 20. As the connecting column 19 moves downward, the wheel 17 at the bottom of the connecting block 16 will move downward synchronously until the bottom of the wheel 17 is lower than the bottom height of the base 4. At this time, the equipment can be conveniently transported by the rolling of the wheel 17, which improves the portability of the equipment during transportation. When the equipment is transported, the operator Pull the handle 15 upward again. When the handle 15 is pulled, the spring 22 will be compressed, and the telescopic column 23 will also shrink. The function of the telescopic column 23 is to limit the extrusion of the spring 22 to prevent the spring 22 from bending during the compression process, and ensure that the force of the spring 22 is always along the axial direction. When the handle 15 moves to a suitable height, the operator pushes the connecting column 19 inward, so that the card column 21 moves to the inner wall of the card slot 18, and uses the card slot 18 to fix and support the card column 21 to prevent it from moving downward. At this time, the wheel 17 also moves to a position higher than the bottom height of the base 4, ensuring that the equipment can be stably supported by the base 4 when placed, thereby improving the stability of the equipment in a non-transportation state.

[0037] Working principle: During the pressure resistance process of the equipment, the pressure of the gas inside the equipment will squeeze the tank shell 2 5, thereby driving the connecting rod 8 to rotate with the rotating shaft 1 7 as the center through 6. While rotating, the connecting rod 8 will drive the slider 10 to slide on the outer wall of the arc-shaped slide 12 through the rotating shaft 2 9, and in this process, the slider 10 will drive the spring 11 to be squeezed, and the rebound characteristics of the spring 11 will be used to relieve and absorb the impact force of the internal pressure of the equipment, thereby enhancing the pressure resistance of the equipment. During the transportation of the equipment, first pull the handle 15 upward, thereby driving the card column 21 to move out from the inner wall of the card slot 18 through the connecting column 19, and then pull the handle 15 outward, thereby driving the card column 21 to move out from the inside of the base 4. At this time, the rebound action of the spring 22 is used. Use force through the sleeve 20 to drive the connecting column 19 to move downward. At this time, the wheel 17 at the bottom of the connecting block 16 will move downward synchronously until the bottom of the wheel 17 is lower than the bottom height of the base 4, thereby facilitating the transportation of the equipment. When the equipment is transported, pull the handle 15 upward. When pulling, the handle 15 will drive the spring 22 to compress and the telescopic column 23 to contract. The telescopic column 23 is used to limit the extrusion of the spring 22 to prevent it from bending. When the handle 15 moves to a suitable height, it pushes the connecting column 19 inward, so that the card column 21 moves to the inner wall of the card slot 18, and the card slot 18 is used to fix and support the card column 21 to prevent it from moving downward. At this time, the wheel 17 also moves to a position higher than the bottom height of the base 4, thereby improving the portability of the equipment during transportation.
