Description

Technical Field

[0001] This invention belongs to the field of air compressors in mechanical manufacturing, and specifically relates to an air compressor that uses water or wind power instead of electricity as its power source; at the same time, it also belongs to the field of energy storage, and specifically relates to a mechanical device that uses compressed air to store water or wind energy. Background Technology

[0002] Compressed air, as a secondary energy source, has a wide range of applications. However, in the past, its processing and production relied on electric power, and air compressors are also called electric air compressors. At the same time, compressed air is the second most valuable energy storage technology after pumped water storage. In the past, it was only used for peak shaving and valley filling, and its function was simply to store electricity. The two patents, with patent numbers ZL2020220826015 and ZL2020208301402, utilize wind and water power to replace electricity in the production of compressed air. This means that compressed air is used to store wind and water energy, expanding the power sources available for compressed air production and enriching the scope of compressed air energy storage. It not only stores electricity but also wind and water, opening up imaginative development prospects for the use of compressed air. Theoretically, through these two technologies, wind and water power under any conditions can be collected and used, providing an effective utilization prospect for large amounts of annual wind and non-high-drop water flow. When humanity can "collect all the wind and water in the world," the energy bottleneck hindering human development is expected to be broken.

[0003] However, as these two technologies are in their early stages, they require further improvement and optimization. The fixed platform is too thick and too high, occupying unnecessary space and making the already limited compression chamber even narrower. The downward movement of the inner cylinder is restricted by the fixed platform, and the gravity push generated by the piston falling freely is stopped at a certain point. This has a certain impact on the complete discharge of compressed gas and the freeing of space in the compression chamber for atmospheric pressure gas to re-enter. It is also detrimental to the increase of compressed air density (pressure) and may lead to problems with low product (compressed air) quality, which need to be improved. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems by providing an improved measure that, based on existing technology, reduces the thickness and height of the fixed platform, allows for the complete removal of compressed gas from the compression chamber, and ensures that the fixed platform is not sealed to the middle of the cylinder, allowing the piston to move downwards over a longer distance. This makes the technology more reasonable and efficient.

[0005] The gravity air compressor of the present invention includes a water turbine or wind turbine driven by water or wind power. The water turbine or wind turbine is connected to and drives a drive shaft. The drive shaft is connected to and drives a gearbox. The gearbox is connected to and drives a crankshaft. The crankshaft is connected to and drives a piston. Bearings provide fixed support and connection for the above components. The piston is connected to the top of an inner cylinder. An inner bladder, which is placed inside the cylinder, forms a compression chamber, allowing air to be compressed within the bladder. The bladder is a tubular (sleeve-shaped, intestine-shaped) soft structure with a relatively large internal space, covered by the inner cylinder. The upper edge of the bladder is fixedly connected to the inner wall of the inner cylinder at a 90-degree right angle. The periphery of the bladder is close to but not connected to the periphery of the inner wall of the inner cylinder. An air inlet and an air outlet are provided on the fixed platform. A low-pressure valve is installed at the air inlet, and a high-pressure valve is installed at the air outlet. The high-pressure and low-pressure valves are connected to corresponding external mechanisms. The connection method is as follows: the high-pressure valve connects to the temporary air storage chamber, and the low-pressure valve connects to the air inlet chamber. The temporary air storage chamber and the air inlet chamber are separated by a partition. The temporary air storage chamber has an air supply pipe with a high-pressure air valve connected to the air tank. A drain valve is installed at the bottom of the temporary air storage chamber. The air inlet chamber is connected to the air inlet pipe and has a filter at the air inlet. The partition connects the bottom of the cylinder body and the bottom of the fixed platform, and is located in the middle of the two bottoms, forming an integral whole. The partition is a flat plate. The fixed platform is the top of the temporary air storage chamber and the air inlet chamber. From the top edge of the fixed platform to the bottom edge of the temporary air storage chamber and the air inlet chamber is an independent circular chamber. This independent circular chamber is only connected to the bottom of the cylinder body and is not connected to any other parts.

[0006] In the gravity air compressor of the present invention, the interlayer formed between the inner side of the cylinder body and the outer side of the independent circular compartment is a heat dissipation layer, and heat dissipation water is injected into the heat dissipation layer to dissipate heat from the heat-generating components.

[0007] The gravity air compressor of this invention has a fixed platform with a disc-shaped surface. The lower edge of the inner bladder is connected to it at the intersection of its slope and flat surface. When the piston and inner cylinder move downwards with the inner bladder, the inner bladder forms inward stacked wrinkles at this point, preventing it from stacking outwards and getting stuck in the heat dissipation layer.

[0008] The gravity air compressor of this invention has an inner bladder made of high-quality soft material that cannot leak air or water. Like an ultra-thin and ultra-soft plastic sheet, it has no obvious elasticity when stretched, and can drain the heat dissipation water that has soaked into the compression chamber and occupied a little space. After compression, it can be folded into a very small volume, occupying only a very small space. At the same time, it must be able to withstand high temperatures of 100 degrees or even higher.

[0009] The gravity air compressor of the present invention has an inner cylinder that is a robust explosion-proof cylinder body that can independently withstand the pressure generated by the high-pressure gas in the compression chamber. Its inner diameter is approximately larger than the outer diameter of the independent circular chamber. Its bottom is open, so that when it moves into the heat dissipation layer, it does not rub against the cylinder body or the independent circular chamber on both sides of the heat dissipation layer. Alternatively, the inner cylinder is a robust explosion-proof cylinder body, but for greater robustness, it can borrow force from the cylinder body to jointly resist the pressure generated by the high-pressure gas in the compression chamber. At the point where it contacts the cylinder body, ball bearings or rollers are provided on the inner side of the cylinder body to reduce frictional resistance.

[0010] The gravity air compressor of this invention uses a piston that serves as a carrier of gravitational potential energy; it is a solid object with maximized density of any geometric shape. It can be manufactured into large, weight-like solid objects that can be added or removed as needed.

[0011] The gravity air compressor of this invention uses a speed-saving gearbox wheel, aiming to maximize the weight of the piston. Speed-saving gearbox wheels are commercially available, and the appropriate size and model can be selected according to needs.

[0012] The gravity air compressor of the present invention uses electronic valves, which are readily available on the market for their specific applications. These valves can be purchased or ordered as needed. The timing of opening or closing, the relationship between them, and the determination of the valve value need to be adjusted according to the site conditions and the strength of the wind and water forces during installation.

[0013] The injection and discharge of cooling water in the heat dissipation layer of the gravity air compressor of this invention need to be handled according to the site conditions, and there is mature experience in the industry that can be referenced. Therefore, no simple and rigid rules are made. Based on the principle that hot water is on top and cold water is on the bottom, the appropriate position of the water tap for injecting cold water and discharging hot water can be set.

[0014] The gravity air compressor of the present invention has a flat crescent-shaped foam body or a similar flat crescent-shaped elastic object on the top of the compression chamber, which is coupled to the disc-shaped platform of the fixed plate. When the piston and the inner cylinder drive it to move downward to the bottom position, it is fully pressed on the disc-shaped platform and the stacked wrinkles of the fixed plate, thereby maximizing the exhaust of compressed air in the compression chamber.

[0015] The gravity air compressor of this invention features a drain valve that is an electronic valve structure consisting of two overlapping high-pressure valves, one open and one closed, with a space between them for water and sediment to settle. This structure is located at the bottom of the temporary air storage chamber, above which the air delivery pipe with its valve device is positioned. Normally, the upper high-pressure valve is open, and the lower high-pressure valve is closed. If there is water or micro-debris in the temporary air storage chamber, it will settle in the space between the two valves. During discharge, according to the preset program of the electronic valve, the upper high-pressure valve closes, and the lower high-pressure valve opens, allowing the water or debris to flow out of the cylinder without leakage of compressed air. After the water or debris has been discharged, the system returns to normal operation by first closing the lower high-pressure valve and then opening the upper high-pressure valve.

[0016] In this invention's gravity air compressor, the inner bladder's function is solely for leak prevention and expansion / contraction. The connection method between the upper and lower edges and the other objects mentioned above can be either a one-time molding process with a connecting plate having pre-drilled screw holes, followed by screw fastening to the inner top of the inner cylinder and the disc surface of the fixed platform (both with pre-drilled screw holes); or a washer-type screw fastening crimping, where pre-drilled screw holes are made on the inner cylinder and the disc surface of the fixed platform, and the washer also has pre-drilled screw holes corresponding to these holes. The upper and lower edges of the inner bladder are then folded into 90-degree right angles and sandwiched between them, and then fastened with screws (the connecting plate and washer are conventional structures, similar to flanges). In short, any traditional connection method is acceptable, as long as it achieves structural perfection; it is not an innovative technology of this invention. Similarly, connection methods mentioned elsewhere in this invention, unless otherwise specified, can be referenced to these methods or corresponding traditional connection methods. Existing or similar traditional connection methods can be found in reality for reference and therefore will not be specifically described. The connection between the flat, crescent-shaped foam body at the top of the compression chamber, or a similar flat, crescent-shaped elastic object, and the top of the inner cylinder can also be made using the method described above.

[0017] The gravity air compressor of this invention includes a water turbine or wind turbine, a drive shaft, a main shaft gear and crankshaft gear of a gearbox, bearings, a crankshaft, a piston, a piston connecting rod, a high-pressure valve, a low-pressure valve, an air inlet, a temporary air storage chamber, an air supply pipe with an air valve device, an air tank, a drain valve, an air pipe, a filter, ball bearings or rollers, and numerous other components or structures not specifically described. These are all conventional technologies or constructions, and their structures are either described in literature or exist as finished products in reality; even if not, they can be custom-made. Regarding the interconnection of these components or structures, the connection between the wind turbine or water turbine and the drive shaft can be threaded or keyed; the connection between the gear and the shaft can be keyed; the connection between the bearing and the shaft can be sleeved; and the connection between the piston connecting rod and the crankshaft and piston can be threaded. Besides these, there are many other connection methods, and any other conventional connection method can be used depending on the situation.

[0018] The gravity air compressor of the present invention, the specifications, models and sizes of all the components, parts and structures involved are determined as needed, and the installation and fixing are carried out by traditional and conventional methods according to the site conditions.

[0019] The gravity air compressor of this invention can also be described as having a main structure consisting of three nested cylinders. The first layer is the outer large cylinder with its opening facing upwards; the second layer is the middle-sized inner cylinder connected to the piston, with its opening facing downwards; the third layer is an independent circular chamber with the smallest diameter, integrated with the first large cylinder at its bottom. During operation, the second cylinder, i.e., the inner cylinder, moves with the piston, its principle being essentially the same as the piston movement in an electric air compressor. The inner cylinder is equivalent to a conventional air cylinder, with the biggest difference being that the inner cylinder contains an inner bladder that compresses the air, completely preventing air leakage. The cylinder only needs to be explosion-proof; there's no need to pursue particularly high precision. This fundamentally solves the problem that the better the sealing of a current cylinder, the greater the resistance. The advantage of the compression chamber formed by the soft, stretchable structure of the inner bladder is that the process of producing compressed air no longer emphasizes that the piston (cylinder) must operate at high speed and continuously. Instead, it can be operated at any speed, like inflating a ball, balloon, or bicycle. It can start when there is wind or water flow. It can operate quickly when the wind or water force is strong and operate slowly when the wind or water force is weak. This is something that the smoothbore compression chamber in electric air compressors cannot do.

[0020] The gravity air compressor of this invention processes and produces compressed air. It can be adapted to local conditions, either as a small workshop producing a single unit or as a large factory producing multiple units in parallel (or connected in series), depending on the specific wind and water power available. This allows for the utilization of all available hydropower and wind energy, increasing the availability of renewable energy and benefiting humanity. If the initial product air pressure is low, it can be increased to meet standards using a booster, making its usability more widespread and universal.

[0021] Detailed Description of the Embodiments: The gravity air compressor of the present invention will be further described below with reference to the accompanying drawings.

[0022] The gravity air compressor of the present invention includes a water turbine or wind turbine (26) driven by water or wind power, the water turbine or wind turbine (26) being connected to and driving a drive shaft (25), the drive shaft (25) being connected to and driving a gearbox (24), the gearbox (24) being connected to and driving a crankshaft (23), the crankshaft (23) being connected to and driving a piston (1), a bearing (50) being a fixed support and connection for the above components, and the piston (1) being connected to the top of the inner cylinder (3). Together, the inner cylinder (3) covers the inner bladder (4) and is placed inside the cylinder body (9) to form a compression chamber (16), so that air is compressed in the inner bladder (4). The inner bladder (4) is a tubular (sleeve-shaped, large intestine-shaped) soft structure with a large internal space. It is covered by the inner cylinder (3) on the outside. The upper edge of the bladder is fixedly connected to the inner wall of the inner cylinder (3) at a right angle of 90 degrees. The inner bladder (4) is close to the inner wall of the inner cylinder (3) but not connected. An air intake is opened on the fixed platform (7). There is one inlet and one outlet. A low-pressure valve (22) is installed at the inlet and a high-pressure valve (21) is installed at the outlet. The high-pressure valve (21) and the low-pressure valve (22) are connected to the corresponding external mechanisms. The connection method is as follows: the high-pressure valve (22) is connected to the temporary gas storage chamber (10) and the low-pressure valve (21) is connected to the inlet chamber (17). The temporary gas storage chamber (10) and the inlet chamber (17) are separated by a partition (14). The temporary gas storage chamber (10) is equipped with a gas supply pipe with a high-pressure gas valve device. (11) Connect the gas tank (12), the bottom of the temporary gas storage chamber (10) is equipped with a drain valve (13), the air inlet chamber (17) is connected to the air inlet pipe (18), the air inlet is equipped with a filter (19), the partition (14) connects the bottom of the cylinder body (9) and the bottom of the fixed platform (7), and is located in the middle of the two bottoms and is connected to the two bottoms vertically. The partition (14) is a flat plate, and the fixed platform (7) is the top of the temporary gas storage chamber (10) and the air inlet chamber (17). Among them, from the upper edge of the fixed platform (7) to the bottom edge of the temporary gas storage chamber (10) and the air inlet chamber (17) is an independent circular chamber (20). The independent circular chamber (20) is only connected to the cylinder body (9) at the same bottom, and is not connected to the surrounding area.

[0023] In the gravity air compressor of the present invention, the interlayer formed between the inner side of the cylinder (9) and the outer side of the independent circular compartment (20) is a heat dissipation layer (8), and heat dissipation water (28) is injected into the heat dissipation layer (8) to dissipate heat from the heat-generating components.

[0024] In the gravity air compressor of the present invention, the surface of the fixed platform (7) is disc-shaped, and the lower edge of the inner bladder (4) is connected to it at the intersection (5) of its slope and plane. When the piston (1) and the inner cylinder (3) move downward with the inner bladder (4), the inner bladder (4) forms stacked wrinkles (6) inward at this point, so as not to stack outward and get stuck in the heat dissipation layer (8).

[0025] The gravity air compressor of the present invention has an inner bladder (4) made of high-quality soft material that cannot leak air or water. Like ultra-thin and ultra-soft plastic paper, it has no obvious elasticity when stretched, and can drain the heat dissipation water (28) that is immersed in the compression chamber (16) and occupies a small space. After compression, it can be folded into a very small volume and only occupies a very small space. At the same time, it must be able to withstand high temperatures of 100 degrees or even higher.

[0026] The gravity air compressor of the present invention has an inner cylinder (3) that is a robust explosion-proof cylinder that can independently withstand the pressure generated by the high-pressure gas in the compression chamber (16). Its inner diameter is about larger than the outer diameter of the independent circular chamber (20). Its bottom is open. When it is inserted into the heat dissipation layer (8) and moves, it does not rub against the cylinder (9) or the independent circular chamber (20) on both sides of the heat dissipation layer (8). Alternatively, the inner cylinder (3) is a robust explosion-proof cylinder, but in order to be more robust, it can borrow force from the cylinder (9) to jointly resist the pressure generated by the high-pressure gas in the compression chamber (16). When it passes the cylinder (9) and comes into contact with it, a ball bearing or roller (2) is provided on the inner side of the cylinder (9) to reduce frictional resistance.

[0027] The gravity air compressor of the present invention uses a piston (1) that is a carrier of gravitational potential energy and is a solid with maximum density of any geometric shape. It can be made into a large solid similar to a weight block and added or removed as needed.

[0028] The gravity air compressor of this invention uses a gearbox wheel (24) as a labor-saving wheel, aiming to maximize the weight of the piston (1). Gearbox wheels are available as finished products on the market, and the size and model can be selected according to needs. If a gearbox is needed, a gearbox can be purchased; if a gearbox wheel is needed, a gearbox wheel can be purchased.

[0029] The gravity air compressor of this invention uses electronic valves, all of which are commercially available as finished products for their intended use. These can be purchased or ordered as needed. The opening and closing times, their relationships, and the determination of the valve values ​​require adjustment based on site conditions and the strength of wind and water pressure during installation (high-pressure valve components must be pressure-resistant). The valve states shown in the diagram are not in operation and are merely illustrative.

[0030] The injection and discharge of cooling water (28) in the heat dissipation layer (8) of the gravity air compressor of the present invention need to be handled according to the site conditions, and there is mature experience in the industry that can be referenced. Therefore, no simple and rigid regulations are made. Based on the principle that hot water is on top and cold water is on the bottom, the appropriate position of the water tap for injecting cold water and discharging hot water can be set.

[0031] The gravity air compressor of the present invention has a flat crescent-shaped foam body (27) or a flat crescent-shaped elastic object (28) similar to foam on the top of the compression chamber (16), which is coupled to the disc-shaped platform of the fixed platform (7). When the piston (1) and the inner cylinder (3) drive it to move downward to the bottom position, it is fully pressed on the disc-shaped platform (5) and the stacked wrinkles (6) of the fixed platform (7), so that the compressed air in the compression chamber (16) is discharged to the maximum extent.

[0032] The gravity air compressor of this invention has a drain valve (13) that is an electronic valve structure consisting of two overlapping high-pressure valves, one open and one closed, with a certain space in between for water and sludge to settle. It is located at the bottom of the temporary air storage chamber (10), and the air supply pipe (11) with the air valve device is positioned higher than it. Normally, the upper high-pressure valve is in the open state, and the lower high-pressure valve is in the closed state. If there is water or sludge in the temporary air storage chamber (10), it will settle in the space between the two. When it is discharged, according to the preset program of the electronic valve, the upper high-pressure valve closes and the lower high-pressure valve opens, and the water or sludge flows out of the cylinder body (9) without leakage of compressed air. After the water or sludge is discharged, it returns to normal. First, the lower high-pressure valve is closed, and then the upper high-pressure valve is opened.

[0033] In the gravity air compressor of the present invention, the inner bladder (4) serves only to prevent leakage and to expand and contract. The connection method between the upper and lower edges and the other objects mentioned above can be as follows: first, it can be molded into shape with a connecting plate with pre-drilled screw holes in one piece, and then it can be fastened to the inner top of the inner cylinder (3) with pre-drilled screw holes and the disc surface of the fixed platform (7) with screws; or it can be a washer-type screw fastening and pressing, that is, pre-drilled screw holes are made on the disc surfaces of the inner cylinder (3) and the fixed platform (7), and pre-drilled screw holes are also made on the washer, corresponding to the pre-drilled screw holes on the disc surfaces of the inner cylinder (3) and the fixed platform (7), and the upper and lower edges of the inner bladder (4) are folded into 90-degree right angles and sandwiched between the two, and then fastened with screws (the connecting plate and the washer are conventional structures, similar to flanges, so they are not shown in the figure). In short, any traditional connection method can be used, as long as the structure is perfect. It is not an innovative technology of the present invention. Similarly, the connection methods involved in other parts of this invention, unless otherwise specified, can be referred to in this connection method, or the corresponding traditional connection method can be adopted. Traditional connection methods can be found in reality or similar methods for reference, so they will not be specifically described or shown in the figure. The connection between the flat crescent-shaped foam body (27) on the inner top of the compression chamber (16), or a flat crescent-shaped elastic object (27) similar to foam, and the inner top of the inner cylinder (3) can also be connected with reference to the above method.

[0034] The gravity air compressor of the present invention comprises a water turbine or wind turbine (26), a drive shaft (25), a gearbox (24), a crankshaft (23), a high-pressure valve (22), a low-pressure valve (21), an air inlet (17), a temporary air storage chamber (10), an air supply pipe (11) with an air valve device, an air tank (12), a drain valve (13), an air pipe (18), a filter (19), ball bearings or rollers (2), and a variety of other components or structures not specifically described. These are all conventional technologies or constructions, and their structures are either described in literature or exist in physical products. Even if they do not exist, they can be custom-made. As mentioned above, the interconnections of these components or structures are also conventional.

[0035] The gravity air compressor of the present invention, the specifications, models and sizes of all the components, parts and structures involved are determined as needed, and the installation and fixing are carried out by traditional and conventional methods according to the site conditions.

[0036] The gravity air compressor of the present invention can also be described as a three-cylinder nested together. The first layer is the outer large cylinder (9) with the cylinder opening facing upwards; the second layer is the middle-sized inner cylinder (3) connected to the piston (1) with its cylinder opening facing downwards; the third layer is an independent circular chamber (27) with its bottom integrated with the first-layer large cylinder (9) and its smallest diameter. In operation, the second cylinder, i.e. the inner cylinder (3), moves with the piston (1), and its principle is generally the same as the piston movement of an electric air compressor. The inner cylinder (3) is equivalent to a conventional cylinder. The biggest difference is that the inner cylinder (3), i.e. the cylinder, has an inner bladder (4) inside, which compresses the air in the bladder, completely preventing air leakage. The cylinder only needs to be explosion-proof and does not need to be particularly precise. This fundamentally solves the problem that the better the sealing of the current cylinder, the greater the resistance. The advantage of the compression chamber (16) formed by the soft and stretchable structure of the inner bladder (4) is that the process of producing compressed air no longer emphasizes that the piston (cylinder) must run at high speed and continuously. Instead, it can be like inflating a ball, balloon, or bicycle, which can be fast or slow, continuous or stopped. It can start when there is wind or water flow. It runs fast when the wind or water force is strong, and runs slower when the wind or water force is weak. This is something that the sliding compression chamber in an electric air compressor cannot do.

[0037] The gravity air compressor of this invention processes and produces compressed air. It can be adapted to local conditions, either as a small workshop producing a single unit or as a large factory producing multiple units in parallel (or connected in series), depending on the specific wind and water power available. This allows for the utilization of all available hydropower and wind energy, increasing the availability of renewable energy and benefiting humanity. If the initial product air pressure is low, it can be increased to meet standards using a booster, making its usability more widespread and universal.

[0038] The gravity air compressor of the present invention operates as follows: water or wind power drives the water wheel or wind turbine (26) to rotate, which in turn drives the transmission shaft (25) to rotate. The transmission shaft (25) then drives the speed change wheel (24) to rotate, which in turn drives the crank (23) to switch from circular motion to up-and-down motion, causing the piston (1) to move up and down accordingly. When the piston (1) moves upward, it lifts the inner cylinder (3) and inner bladder (4) upward, while the low-pressure valve (21) opens and the high-pressure valve (22) closes, allowing air to enter the compression chamber (16). When the piston (1) moves downward, it squeezes the inner cylinder (3) and inner bladder (4) downward, while the low-pressure valve (21) closes and the high-pressure valve (22) opens, gradually reducing the size of the compression chamber (16), and the air inside is gradually compressed and expelled into the temporary air storage chamber (10). As the piston (1) moves up and down cyclically, the intake and exhaust of the compression chamber (16) also repeats. When the density of compressed air in the temporary storage chamber (10) reaches the predetermined standard, the valve on the air supply pipe (11) with the air valve device is opened, and compressed gas enters the air tank (12) one after another until it is full. Replace with a new empty tank.
