Description

Technical Field

[0001] This invention relates to the field of gas source cylinder technology, specifically a multi-chamber gas source cylinder. Background Technology

[0002] Gas cylinders, as high-pressure gas storage devices, are widely used in fields such as drone launch, net launching, and pneumatic tools. Taking drone net launching as an example, existing technologies typically use single-chamber gas cylinders. During use, a firing mechanism punctures the seal of the cylinder, releasing the high-pressure gas instantaneously, thereby propelling the net out.

[0003] However, this type of single-chamber gas cylinder has obvious shortcomings in actual use: the gas release is instantaneous and explosive, the gas release flow is uncontrollable, and it is difficult to achieve continuous and stable gas output; for launch scenarios that require a longer duration or a specific thrust curve (such as cold gas launch of folding wings of UAVs), single-chamber gas cylinders are difficult to meet the requirements.

[0004] To address the aforementioned issues, existing technologies have proposed a multi-cylinder parallel gas supply scheme, which involves setting up multiple independent gas cylinders and controlling their sequential opening via valves to achieve segmented gas supply. However, this scheme is structurally complex, bulky, and requires each cylinder to be filled separately, resulting in cumbersome operation and high costs.

[0005] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a multi-chamber gas source cylinder. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a multi-chamber gas source cylinder to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a multi-chamber gas source cylinder, including a gas source cylinder, a partition fixedly connected inside the gas source cylinder, the partition dividing the interior of the gas source cylinder into at least two gas storage chambers, and a vent hole corresponding to the gas storage chamber is opened on the gas source cylinder, the vent hole being sealed with a sealing plate.

[0008] In one or more embodiments of the present invention, the medium filled in the different gas storage chambers is different from each other.

[0009] In one or more embodiments of the present invention, the pressure in different gas storage chambers is different.

[0010] In one or more embodiments of the present invention, the diameter of the connecting hole is smaller than the diameter of the vent hole.

[0011] In one or more embodiments of the present invention, the partition is integrally formed or welded to the gas source cylinder.

[0012] In one or more embodiments of the present invention, the volumes of each of the gas storage chambers are different.

[0013] The beneficial effects of this invention are as follows: 1. Through partitions or independent unit structures, each gas storage chamber is completely isolated, eliminating cross-flow between gases of different pressures or media, and avoiding the risk of chemical reactions or pressure changes caused by gas mixing. 2. Since each chamber is independent, different pressures can be set according to the actual needs of the connected needles. For long needles, a lower pressure can be set, which effectively reduces the gas impact at the moment of initial release, prevents needle damage or material splashing, and makes the operation more stable and safe. 3. The inner diameter of each gas storage chamber is relatively small. Under the premise of meeting the same pressure rating, the wall thickness of the chamber can be designed to be thinner. Compared with a single large-capacity gas cylinder, this multi-chamber structure greatly reduces the amount of metal or composite materials used, making the entire gas source cylinder smaller and lighter, and easier to carry and hand-operate. 4. Each gas storage chamber is interconnected through a connecting hole, enabling simultaneous filling under the same pressure, which is simple to operate. Each gas storage chamber has a different volume, and with a vent hole that is much larger than the connecting hole, different gas flow rates can be generated when the seal is punctured in sequence, thereby achieving linear gas release. The overall structure is compact and does not require a complex valve control system, making it suitable for scenarios with specific requirements for gas release curves, such as UAV launch and network replenishment.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: like Figure 1 As shown, a multi-chamber gas source cylinder according to one embodiment of the present invention includes a gas source cylinder 1, with a partition 13 fixedly connected inside the gas source cylinder 1. The partition 13 divides the interior of the gas source cylinder 1 into at least three gas storage chambers 14. In this embodiment, the gas source cylinder 1 is divided into three gas storage chambers 14 by the partition 13, thereby generating different gas flow rates when gas is released from each gas storage chamber 14.

[0019] The partition 13 is fixedly connected to the inner wall of the gas source cylinder 1 by welding, integral molding, or sealing with a sealing ring to ensure that each gas storage chamber 14 is independent and not interconnected. As a preferred embodiment, the partition 13 is sealed and fixed by welding or a sealing ring. Alternatively, the partition 13 can also be integrally molded with the gas source cylinder 1, for example, by casting or extrusion molding to form the partition 13 directly inside the gas source cylinder 1, thereby eliminating subsequent assembly steps, improving production efficiency, and reducing the risk of leakage.

[0020] The gas source cylinder 1 has a vent hole 11 corresponding to the gas storage chamber 14. Specifically, each gas storage chamber 14 is provided with at least one vent hole 11, which is used to release the gas in the gas storage chamber 14 to the outside. The vent hole 11 is sealed with a sealing strip 12. When it is necessary to release the gas in a certain gas storage chamber 14, the sealing strip 12 corresponding to that gas storage chamber 14 can be broken by puncturing, breaking, or other means to open the vent hole 11, and the high-pressure gas in the gas storage chamber 14 can be released to the outside through the vent hole 11. The thickness and material of the sealing strip 12 can be selected according to the design pressure in the gas storage chamber 14 to ensure that the sealing strip 12 can reliably seal the vent hole 11 to prevent gas leakage when not in use; and can be easily punctured or broken when gas needs to be released.

[0021] It should be noted that since each gas storage chamber 14 is independent and not connected to each other, a modular combination can be quickly achieved to achieve a multi-needle release method.

[0022] In one preferred embodiment, the media filled in the different gas storage chambers 14 are different. For example, the first gas storage chamber 14 is filled with nitrogen, the second gas storage chamber 14 is filled with helium, and the third gas storage chamber 14 is filled with carbon dioxide, etc. In this way, the same gas source cylinder 1 can simultaneously provide multiple different types of gases to meet the needs of different gases in different application scenarios. Of course, the media filled in the different gas storage chambers 14 can also be the same, for example, all of them can be filled with compressed air to increase the total gas storage capacity.

[0023] In one preferred embodiment, the pressure within each of the different gas storage chambers 14 is different. Setting different pressures in different gas storage chambers 14 can achieve differentiated gas release effects.

[0024] Specifically, for certain applications that require a smaller initial release impact (for example, the chamber pressure of the corresponding long puncture needle can be set to be lower than that of other puncture needles), the pressure of the gas storage chamber 14 of the corresponding long puncture needle can be set to be lower, thereby reducing the impact force during initial release and improving the safety and stability of use.

[0025] Because the partition 13 divides the interior of the gas source cylinder 1 into multiple gas storage chambers 14, the inner diameter of each gas storage chamber 14 is significantly smaller than the overall inner diameter of the gas source cylinder 1. Under the same wall thickness conditions, the chamber with the smaller inner diameter has a higher pressure resistance and better safety. Alternatively, while meeting the same pressure requirements, the wall thickness of each gas storage chamber 14 can be designed to be relatively thin, thereby making the entire gas source cylinder 1 smaller in size and lighter in weight, making it easier to carry and use.

[0026] Example 2: like Figure 2 As shown, the volumes of each gas storage chamber 14 are different, and the partition 13 has a connecting hole 131 that connects two adjacent gas storage chambers 14. Through the connecting hole 131, gas communication is formed between the various gas storage chambers 14. During inflation, external high-pressure gas is injected into one gas storage chamber 14 through the vent hole 11, and diffuses sequentially to other gas storage chambers 14 through the connecting hole 131. Due to the conductive effect of the connecting hole 131, the gas pressure stored in each gas storage chamber 14 eventually reaches the same level, thereby achieving simultaneous inflation of all gas storage chambers 14 under the same pressure, eliminating the need to inflate each chamber separately, and greatly simplifying the inflation operation.

[0027] The gas source cylinder 1 has vent holes 11 corresponding to the gas storage chambers 14, and each vent hole 11 is sealed with a sealing plate 12. The sealing plate 12 is sealed and fixed to the vent hole 11 by welding, integral molding or pressing, etc., to ensure that each gas storage chamber 14 maintains good airtightness when not in use. In use, the sealing plates 12 of each gas storage chamber 14 are punctured by a firing mechanism such as a firing pin or a piercing needle. When the sealing plate 12 of a certain gas storage chamber 14 is punctured, the high-pressure gas in that gas storage chamber 14 is released outward through the vent hole 11. Since the diameter of the connecting hole 131 is much smaller than the diameter of the vent hole 11, and the volume of each gas storage chamber 14 is different, the gas flow rate released by each gas storage chamber 14 during venting is also different.

[0028] Specifically, the larger gas storage chamber 14 stores a larger total amount of gas and releases a larger gas flow rate under the same pressure difference; the smaller gas storage chamber 14 releases a relatively smaller gas flow rate. By rationally designing the volume ratio of each gas storage chamber 14 and the aperture of the connecting hole 131, the gas release flow rate at each stage can be precisely controlled, achieving linear gas release or release according to a predetermined curve.

[0029] In this embodiment, the body of the gas source cylinder 1 can be made of high-strength metal material to withstand high-pressure gas. The partition 13 is integrally formed with the gas source cylinder 1 or fixedly connected by welding to ensure the sealing between the partition 13 and the cylinder body. The diameter of the connecting hole 131 can be set according to the actual required gas release rate.

[0030] The sealing plate 12 can be punctured by mechanical puncture, electronic puncture, or rupture disc. Each vent hole 11 can be arranged sequentially along the axis of the gas source cylinder 1 so that the firing mechanism can puncture each sealing plate 12 in sequence to achieve segmented and orderly gas release.

[0031] Obviously, the above-described embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
