An externally powered automatic recirculation gas pressurization device

Abstract

An automatic circulating gas pressurizing device without external power belongs to the technical field of fluid pressure actuator and gas pressurizing. The device comprises a power cylinder, a compression cylinder, a power piston, a compression piston, a lever assembly, an automatic air intake and exhaust control mechanism and a counterweight automatic grabbing and releasing mechanism. The counterweight automatic grabbing and releasing mechanism comprises an elastic buckle and a rotary support rod. The power cylinder drives the power piston to intake air, and the power piston drives the compression piston to compress gas upward after the force is amplified by the lever. When the compression piston goes upward, the elastic buckle hooks the counterweight, and the rotary support rod holds up the counterweight at a set position. At the same time, the elastic buckle releases the counterweight, and the piston continues to go upward to increase compression. After the compression cylinder exhausts, the compression piston goes downward, and the rotary support rod no longer holds up the counterweight at a set position. At the same time, the elastic buckle hooks the counterweight again, and the gravity is used to assist the reset. The device realizes continuous circulating pressurization only by the pressure of the gas itself, and does not need power, which is suitable for explosion-proof and other non-electric environments.

Description

Technical Field

[0001] This invention relates to an automatic circulating gas booster device without external power, belonging to the field of fluid pressure actuators and gas booster technology. Background Technology

[0002] Gas booster devices are widely used in industrial pneumatic systems, food modified atmosphere preservation, medical gas distribution, mine ventilation, and other fields. Traditional gas booster equipment typically uses electric compressors as a power source, which are complex in structure, bulky, and energy-intensive. They also rely on external power or control systems, limiting their use in special environments such as those without electricity or requiring explosion-proof conditions.

[0003] Although some gas booster devices that do not require external power have emerged in the existing technology, they generally have the following shortcomings: First, the automatic cycle of the booster process depends on a special air control valve group or external triggering mechanism, which is complex in structure and high in cost; Second, after the compression piston completes one compression, its reset process lacks a reliable auxiliary mechanism, which is easily affected by the fluctuation of the gas source pressure, resulting in incomplete reset or failure to automatically enter the next compression, making it difficult to achieve continuous and stable booster operation. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned problems existing in the prior art and provide an automatic circulating gas booster device without external power, which is simple in structure, reliable in resetting, and can automatically complete the compression, degassing, resetting and recompression cycle solely by the pressure of the gas itself.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic circulating gas booster device without external power includes a power cylinder, a compression cylinder, a power piston, a compression piston, a lever assembly, an intake and exhaust control mechanism, and an automatic counterweight grabbing and releasing mechanism. The power cylinder contains a power piston, and the compression cylinder contains a compression piston. The lever assembly connects the power piston and the compression piston, amplifying the driving force of the power piston to drive the compression piston. The intake and exhaust control mechanism is located in the intake and exhaust pipes of the power cylinder and the compression cylinder, controlling the opening and closing of the air ports. The automatic counterweight grabbing and releasing mechanism releases the counterweight when the compression piston rises to a set position and hooks the counterweight when it descends to a set position to assist in resetting.

[0007] Preferably, the lever assembly includes lever one and lever two symmetrically distributed on both sides of the cylinder body. Lever one and lever two are each composed of two rods and a fulcrum. The two rods are arranged at an angle around the corresponding fulcrum, and the fulcrum is located close to the compression cylinder body.

[0008] Preferably, the intake and exhaust control mechanism includes an intake pipe and an exhaust pipe respectively disposed above the power cylinder and the compression cylinder, for a total of four pipes. Each pipe contains a slider, which is fixedly connected to the corresponding piston via a connecting rod. The slider slides within the pipe as the piston moves, and the movement of the slider blocks or opens the corresponding air port, thereby controlling the gas flow.

[0009] Preferably, the automatic counterweight grasping and releasing mechanism includes an elastic buckle connected to the compression piston, a rotatable first rotating support rod and a second rotating support rod, and a spring buckle and a hook portion disposed on the counterweight; the end of the elastic buckle is provided with a cylindrical head, and the first rotating support rod is provided with a limiting boss; the compression piston is also connected to a first vertical connecting rod and a second vertical connecting rod, which are respectively used to push the first rotating support rod and the second rotating support rod to rotate when the compression piston moves downward; the elastic buckle is configured to cooperate with the limiting boss, and the elastic buckle and the hook portion are also configured to cooperate with each other. The parts are detachably connected; the spring buckle cooperates with the first and second rotating support rods, so that when the compression piston moves upward to the set position, the first and second rotating support rods lift the spring buckle, thereby lifting the counterweight. At the same time, the limiting boss pushes open the cylindrical head at the end of the elastic buckle, causing the elastic buckle to release the hook part, thus releasing the counterweight. When moving downward, the first and second vertical connecting rods push the first and second rotating support rods to rotate, causing the limiting boss to move away, the elastic buckle to reset and hook the hook part, and the counterweight assists in resetting using its gravity.

[0010] Preferably, the fulcrum structure of the first and second rotating support rods is as follows: a first support rod and a second support rod are provided, the first support rod and the second support rod are fixed and installed on the cylinder base in a cross shape; the two ends of the second support rod are respectively provided with a first fulcrum and a second fulcrum, the first rotating support rod is rotatably installed on the first fulcrum, and the second rotating support rod is rotatably installed on the second fulcrum; the rotation axis of the first and second rotating support rods is perpendicular to the movement direction of the compression piston.

[0011] Preferably, the counterweight has an avoidance notch on the side facing the limiting boss to prevent the limiting boss from interfering with the counterweight during rotation.

[0012] Preferably, the power cylinder intake pipe has an intake port for connecting to an external low-pressure air source; the power cylinder exhaust pipe has an exhaust port for connecting to the atmosphere; the compression cylinder intake pipe has an intake port for connecting to an external low-pressure air source; the compression cylinder exhaust pipe has an exhaust port for connecting to a high-pressure air storage container or the user end; and the upper ends of the power cylinder intake pipe, power cylinder exhaust pipe, and compression cylinder exhaust pipe are all open structures.

[0013] The working process and principle of the device of the present invention will be explained below.

[0014] Initially, neither the power cylinder nor the compression cylinder is receiving air, and all sliders are in their initial positions. When an external low-pressure air source is introduced, the low-pressure gas simultaneously enters both the power cylinder and the compression cylinder. The intake air in the power cylinder drives the power piston, which, through a lever assembly, amplifies the force and drives the compression piston upwards, compressing the gas within the compression cylinder. During this process, the sliders connected to the power piston and compression piston move with the pistons, sliding within their corresponding intake and exhaust pipes. When a slider reaches an air inlet position, it blocks or opens the corresponding gas passage, thus achieving automatic switching between intake and exhaust without the need for an external pneumatic control valve assembly.

[0015] As the compression piston moves upward, the elastic latch hooks onto the counterweight via the hook part and rises together. When the piston reaches the set position, the first and second rotating support rods lift the spring latch on the counterweight, thereby raising the counterweight. Simultaneously, the limiting boss on the first rotating support rod pushes open the cylindrical head at the end of the elastic latch, causing the elastic latch to release the hook part on the counterweight. The counterweight is then supported by the rotating support rods and stops rising. After the counterweight is released, the compression piston continues to move upward to the highest point, completing the compression stroke. After the compression cylinder completes compression, it automatically exhausts air under the action of the intake and exhaust control mechanism. At the same time, the intake port of the power cylinder automatically closes and the exhaust port automatically opens, causing the air pressure inside the compression cylinder to drop. Under the action of the intake pressure, the compression piston begins to move downward.

[0016] During the downward movement, the first and second vertical connecting rods connected to the compression piston respectively push the first and second rotating support rods to rotate, causing the limiting boss on the first rotating support rod to move away from the cylindrical head at the end of the elastic buckle. To avoid interference between the limiting boss and the counterweight when rotating, the counterweight has a clearance notch on the side facing the limiting boss. As the limiting boss moves away, the elastic buckle resets itself by its own elastic force and re-hooks the hook on the counterweight; at the same time, the rotation of the rotating support rod also causes the spring buckle to disengage from the support rod, and the counterweight moves downward with the compression piston under the action of gravity, using the gravity of the counterweight to assist the compression piston in resetting. After resetting, the intake and exhaust control mechanism automatically switches, and the device enters the next compression cycle. This process repeats, and the device can achieve continuous and automatic cyclic pressurization solely based on the pressure of the gas itself, without the need for external power or manual intervention.

[0017] Compared with the prior art, the present invention has the following advantages: the device is driven only by the pressure of the gas itself, without the need for external power, making it particularly suitable for special environments such as those without electricity or explosion-proof environments; through the coordinated work of the intake and exhaust control mechanism and the automatic counterweight grasping and releasing mechanism, the device can automatically complete the complete cycle of compression, exhaust, reset and recompression without manual intervention or external control; the automatic counterweight grasping and releasing mechanism adopts the mechanical cooperation of elastic buckle and limiting boss, and uses the gravity of the counterweight to assist in reset when the compression piston moves downward, avoiding the influence of gas source pressure fluctuations on the reset process and ensuring the continuous and stable operation of the device; adopting a pure mechanical linkage structure, it does not require complex pneumatic control valve groups or electronic components, and the overall structure is simple, the manufacturing cost is low, and it is easy to maintain.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 3As shown, the automatic circulating gas booster device without external power in this embodiment includes a power cylinder 1, a compression cylinder 2, a power piston 3, a compression piston 4, a lever assembly 5, an intake and exhaust control mechanism, an automatic counterweight grasping and releasing mechanism, and a cylinder base 21. Both the power cylinder 1 and the compression cylinder 2 are fixed to the cylinder base 21. The power piston 3 is located inside the power cylinder 1, and the compression piston 4 is located inside the compression cylinder 2. The lever assembly 5 includes a first lever 5a and a second lever 5b symmetrically distributed on both sides of the cylinder. The first lever 5a consists of two rods and a fulcrum 14, and the second lever 5b consists of two rods and a fulcrum 15. The two rods are arranged at an angle around the corresponding fulcrum, and the fulcrum is located close to the compression cylinder 2. The power piston 3 and the compression piston 4 are connected through the lever assembly 5, which amplifies the driving force of the power piston 3 to drive the compression piston 4.

[0024] The intake and exhaust control mechanism includes a power cylinder intake pipe 10 and a power cylinder exhaust pipe 13 located above the power cylinder body 1, and a compression cylinder intake pipe 11 and a compression cylinder exhaust pipe 12 located above the compression cylinder body 2. The upper ends of the power cylinder intake pipe 10, power cylinder exhaust pipe 13, and compression cylinder exhaust pipe 12 are all open to prevent the normal sliding of the sliders from being restricted by a closed upper end. Each pipe has a corresponding air port on its side wall. Specifically, the power cylinder intake pipe 10 has an air inlet 22 on its side wall for connecting to an external low-pressure air source; the power cylinder exhaust pipe 13 has an exhaust port 25 on its side wall for connecting to the atmosphere; the compression cylinder intake pipe 11 has an air inlet 23 at its upper end for connecting to an external low-pressure air source; and the compression cylinder exhaust pipe 12 has an exhaust port 24 on its side wall for connecting to a high-pressure air storage container or the user end. Slider 1 26, slider 27, slider 3 28, and slider 4 29 are respectively installed in the four pipes. Each slider is fixedly connected to its corresponding piston via a connecting rod: slider one (26) and slider four (29) are connected to the power piston 3, and slider two (27) and slider three (28) are connected to the compression piston 4. As the piston moves, the slider slides inside the pipe. When the slider moves to the side wall air port position, it blocks or opens the corresponding gas passage, thereby realizing the automatic switching between air intake and exhaust.

[0025] The automatic counterweight grabbing and releasing mechanism includes an elastic buckle 6, a first rotating support rod 7a, a second rotating support rod 7b, a spring buckle 16, a hook part 17, a first support rod 18, a second support rod 19, a first vertical connecting rod 20a, a second vertical connecting rod 20b, and a counterweight 8. The elastic buckle 6 is connected to the compression piston 4 and has a cylindrical head at its end. The first rotating support rod 7a has a limiting boss 9, while the second rotating support rod 7b does not have a limiting boss. The first support rod 18 and the second support rod 19 are fixed in a cross shape and installed on the cylinder base 21; the two ends of the second support rod 19 are respectively provided with a first fulcrum and a second fulcrum. The first rotating support rod 7a is rotatably installed on the first fulcrum, and the second rotating support rod 7b is rotatably installed on the second fulcrum. The rotation axes of both are perpendicular to the movement direction of the compression piston 4. The compression piston 4 is also connected to a first vertical connecting rod 20a and a second vertical connecting rod 20b, which are used to drive the first rotating support rod 7a and the second rotating support rod 7b to rotate during downward movement. The counterweight 8 is provided with a spring buckle 16 and a hook part 17. The spring buckle 16 is used to cooperate with the first rotating support rod 7a and the second rotating support rod 7b to achieve lifting; the hook part 17 is used to detachably connect with the elastic buckle 6. The counterweight 8 has an avoidance notch 30 on the side facing the limiting boss 9 to avoid interference when the limiting boss 9 rotates.

[0026] The working process of this device is explained in detail below with reference to the slider position. For example... Figure 2 As shown, the initial positions of slider 1 (26), slider 2 (27), slider 3 (28), and slider 4 (29) are defined as C1, A1, B1, and D1, respectively. During subsequent movement, the key marker positions for each slider are as follows: slider 1 has C1, C2, and C3; slider 2 has A1, A2, and A3; slider 3 has B1, B2, B3, B4, B5, and B6; and slider 4 has D1, D2, and D3. These marker positions are only used to describe critical states during the working process; the actual movement of the sliders is continuous and not limited to these positions.

[0027] Initial state: Neither the power cylinder 1 nor the compression cylinder 2 is receiving air. The compression piston 4 is located at the bottom of the compression cylinder 2 (the lowest point where it can no longer move downwards), and the power piston 3 is located at the top of the power cylinder 1 (the highest point where it can no longer move upwards). Slider 1 26 is located at C1, slider 2 27 at A1, slider 3 28 at B1, and slider 4 29 at D1. An external low-pressure air source is connected to the air inlet 22 of the power cylinder intake pipe and the air inlet 23 of the compression cylinder intake pipe.

[0028] After the air source is turned on, low-pressure gas enters the power cylinder 1 and the compression cylinder 2. Since the compression piston is already at the bottom and cannot move downwards, while the power piston is at the top, the air pressure in the power cylinder pushes the power piston 3 downwards, which in turn drives the compression piston 4 upwards through lever 5a and lever 5b.

[0029] As the compression piston 4 moves upward, the connected slider 27 also moves upward. When slider 27 moves to position A3, the air inlet 23 of the compression cylinder air inlet pipe 11 is closed, while air continues to flow into the power cylinder. The compression piston 4 continues to move upward, and the power piston 3 moves downward, compressing the gas in the compression cylinder.

[0030] As the compression piston 4 continues to move upward, during this process (i.e., while the slider 3 moves from B1 to B2), the elastic buckle 6 hooks the counterweight 8 through the hook part 17 and rises together. When the slider 3 28 moves to the B2 position, the first rotating support rod 7a and the second rotating support rod 7b lift the spring buckle 16 and raise the counterweight 8. At the same time, the limiting boss 9 on the first rotating support rod 7a pushes open the cylindrical head at the end of the elastic buckle 6, causing the elastic buckle 6 to release the hook part 17, and the counterweight 8 is supported by the rotating support rod and stops rising.

[0031] As the compression piston 4 moves upward, when slider 3 28 moves to position B3, the exhaust port 24 of the compression cylinder exhaust pipe is opened, and the high-pressure gas in the compression cylinder is discharged through exhaust port 24, connecting to the high-pressure gas storage container or the user end through the compression cylinder exhaust pipe 12. At this time, slider 1 26, connected to the power piston 3, moves downward to position C3, and the air inlet 22 of the power cylinder intake pipe is closed. Subsequently, the compression piston 4 continues to move upward, and when slider 3 28 moves to position B5, due to the downward movement of the power piston 3, slider 4 29, connected to the power piston 3, moves downward to position D3, and the exhaust port 25 of the power cylinder exhaust pipe is opened, allowing the gas in the power cylinder to be discharged to the atmosphere through exhaust port 25.

[0032] At this time, as the compression cylinder continues to exhaust gas, the compression piston 4 continues to move upward. When the slider 3 28 moves to position B6, as the gas in the compression cylinder is discharged, its pressure gradually decreases to below the intake pressure of the external low-pressure gas source. Under this pressure difference, the compression piston 4 begins to move downward.

[0033] The compression piston 4 moves downward, causing the slider 3 28 to move downward. When the slider 3 28 descends to position B4, the slider 4 29, which is connected to the power piston 3, moves upward to position D2, closing the exhaust port 25 of the power cylinder exhaust pipe.

[0034] As the compression piston 4 continues to descend, when slider 3 28 reaches position B2, the exhaust port 24 of the compression cylinder exhaust pipe is closed, and slider 1 26, connected to the power piston 3, moves upward to position C2, opening the air inlet 22 of the power cylinder intake pipe. At this time, the first vertical connecting rod 20a and the second vertical connecting rod 20b push the first rotating support rod 7a and the second rotating support rod 7b to rotate, causing the limiting boss 9 to move away from the end cylindrical head of the elastic buckle 6; the elastic buckle 6 resets and re-hooks the hook part 17 on the counterweight 8; simultaneously, after the rotating support rod rotates, it no longer supports the spring buckle 16, and the counterweight 8, under the action of gravity, applies a downward pulling force to the compression piston 4 through the hook part 17.

[0035] Under the gravity of the counterweight 8, the compression piston 4 continues to move downward to the bottom, completing a complete working cycle, realizing compression, exhaust and reset, and then entering the recompression stage.

[0036] Subsequently, due to the re-intake of air into the power cylinder, the compression piston 4 moves upward again, repeating the above steps (starting from

[0029] ), thereby achieving continuous automatic cyclic pressurization. Throughout the entire operation, all moving parts are driven by gas pressure, and the cycles of compression, exhaust, reset, and recompression are automatically completed through mechanical linkage, without the need for external power or manual intervention.

[0037] The device in this embodiment has a compact structure and reliable operation, enabling continuous automatic cyclic pressurization. It is suitable for gas pressurization needs in special environments such as those without electricity or in explosion-proof conditions. The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural or procedural modifications made based on the description and drawings of the present invention are similarly included within the patent protection scope of the present invention.
