Description

Technical Field

[0001] This utility model relates to the field of booster system technology, specifically a rapid booster system based on a light air cannon. Background Technology

[0002] A light gas cannon is a high-speed launching device that uses light gas (such as hydrogen or helium) as a propulsion medium. It is mainly used in scientific experiments such as ultra-high-speed impact simulation, materials dynamics research, and spacecraft protection testing. The pressurization system of the light gas cannon is the core component for achieving ultra-high-speed projectile launch. It is mainly used to compress light gas (such as hydrogen or helium) to a high-pressure state, thereby driving the projectile to achieve extremely high speeds.

[0003] Traditional booster systems often use a single medium to drive pressure increase, which results in insufficient response speed. Furthermore, the piston in a traditional booster system may wear down after prolonged reciprocating motion, leading to poor sealing and affecting the lifespan of the device. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a rapid pressurization system based on a light air gun to solve the existing problems mentioned in the background art.

A push rod is fixedly connected to the middle of the piston's outer surface, and a first spring is fixedly connected to the end of the push rod away from the piston. A fixing sleeve and a pressure sensor are fixedly connected to the inner wall of the air chamber. A sealing ring is disposed on the side of the piston's outer surface, and a guide ring is disposed on the side of the sealing ring away from the piston. A second spring is disposed on the inner surface of the sealing ring, and an elastic ring is disposed at the end of the second spring away from the sealing ring.

[0007] Preferably, the end of the return oil pipe furthest from the oil tank is connected to the oil chamber, and a pressure relief valve is installed inside the return oil pipe.

[0011] Beneficial effects

[0012] This invention provides a rapid pressurization system based on a lightweight gas cannon. It offers the following advantages:

[0013] (1) The rapid pressurization system based on the light air gun, through the cooperation between the oil tank, oil pump, air source box, piston, air chamber and oil chamber, adopts the oil and gas dual-medium coupling drive mechanism. The oil chamber pushes the piston to quickly compress the gas in the air chamber through high pressure oil. By utilizing the high density and low compressibility of oil, the energy loss problem caused by the compressibility of gas in the pure pneumatic system is overcome, and the system response speed and energy efficiency are significantly improved. At the same time, during the piston reset stage, through the synergistic effect of the elastic potential energy of the first spring and the residual pressure of the air chamber, the piston can be quickly reset without relying on an external motor or additional power source, which meets the millisecond-level requirements of instantaneous high pressure in scenarios such as light air guns.

[0014] (2) The rapid pressurization system based on the light air gun forms a multi-stage adaptive sealing system through the cooperation between the sealing ring, elastic ring, guide ring and second spring. Under high pressure conditions, the second spring continuously applies radial pressure to the sealing ring, so that the sealing ring is always tightly attached to the inner wall of the cylinder, further improving the sealing performance of the piston and extending the service life of the device.

[0020] Example 1:

[0021] like Figure 1-3 As shown, this utility model provides a rapid pressurization system based on a light air cannon, including a cylinder body 1, an oil tank 2, an oil pump 3, and an air source box 4. A piston 5 is arranged inside the cylinder body 1, and an oil chamber 6 and an air chamber 7 are arranged on both sides of the piston 5. An oil suction pipe 8 and an oil inlet pipe 9 are arranged on the outer surface of the oil pump 3. An oil return pipe 10 is arranged on the outer surface of the oil tank 2. An air inlet pipe 17 is arranged on the outer surface of the air source box 4. An exhaust pipe 15 is arranged at the end of the cylinder body 1. A push rod 12 is fixedly connected to the middle of the outer surface of the piston 5. A first spring 14 is fixedly connected to the end of the push rod 12 away from the piston 5. A fixing sleeve 13 and a pressure sensor 23 are fixedly connected to the inner wall of the air chamber 7. A sealing ring 19 is arranged on the side of the outer surface of the piston 5. A guide ring 21 is arranged on the side of the sealing ring 19 away from the piston 5. A second spring 20 is arranged on the inner surface of the sealing ring 19. An elastic ring 22 is arranged on the end of the second spring 20 away from the sealing ring 19.

[0022] Specifically, the end of the oil extraction pipe 8 furthest from the oil pump 3 is connected to the oil tank 2, and the end of the oil inlet pipe 9 furthest from the oil pump 3 is connected to the oil chamber 6.

[0023] Specifically, the end of the return oil pipe 10 away from the oil tank 2 is connected to the oil chamber 6, and a pressure relief valve 11 is installed inside the return oil pipe 10.

[0024] Specifically, the outer surface of the push rod 12 is fitted inside the fixed sleeve 13, and the end of the first spring 14 away from the push rod 12 is fixedly connected to the inner surface of the fixed sleeve 13.

[0025] Specifically, the ends of the exhaust pipe 15 and the intake pipe 17 are both connected to the air chamber 7. An exhaust one-way valve 16 is installed inside the exhaust pipe 15, and an intake one-way valve 18 is installed inside the intake pipe 17.

[0026] Specifically, the second spring 20 and the elastic ring 22 are disposed at the interval between the piston 5 and the guide ring 21. The sealing ring 19, the second spring 20, the guide ring 21 and the elastic ring 22 are symmetrically disposed on both sides of the piston 5. The outer surfaces of the sealing ring 19 and the guide ring 21 are adapted to the inner surface of the cylinder 1.

[0027] The working principle and beneficial effects of the above embodiments.

[0028] During operation, in the initial inflation phase, before system startup, piston 5 is located at the right end of cylinder 1, and oil chamber 6 has its smallest volume. Air source box 4 injects low-pressure gas into air chamber 7 through intake pipe 17. Intake check valve 18 opens under gas pressure until it closes after the pressure in air chamber 7 is balanced with the air source. In the pressurization phase, after oil pump 3 starts, oil in oil tank 2 is drawn in through oil suction pipe 8 and injected into oil chamber 6 through oil inlet pipe 9. The oil pressure pushes piston 5 to the left, compressing the gas in air chamber 7. During this process, elastic ring 22 expands radially under the pressure of the oil, applying pressure to the second spring 20. Sealing rings 19 on both sides of piston 5 are pressed tightly against the inner wall of cylinder 1 by the elastic force of the second spring 20, further improving the sealing performance of piston 5. Pressure sensor 23 monitors the pressure value of air chamber 7 in real time. When a set threshold is reached, exhaust check valve 16 opens. When piston 5 moves to the left, push rod 12 slides along fixed sleeve 13, first spring 14 is compressed and stores reset energy. During the high pressure release stage, after exhaust check valve 16 opens, high pressure gas in air chamber 7 is quickly output to light air cannon through exhaust pipe 15. During gas release, oil pump 3 continuously supplies oil to maintain piston 5 position and ensure pressure stability. During reset and replenishment stage, after pressurization is completed, pressure relief valve 11 opens, and high pressure oil in oil chamber 6 flows back to oil tank 2 through return oil pipe 10. Under the combined action of the elastic force of first spring 14 and residual pressure in air chamber 7, piston 5 moves to the right to reset. At the same time, when piston 5 moves to the right, the volume of air chamber 7 increases and the pressure decreases. Intake check valve 18 opens again to replenish new gas. Guide ring 21 and elastic ring 22 dynamically adjust the contact pressure of sealing ring 19 with piston 5 movement to avoid seal failure during reset.
