Description

Technical Field

[0001] The invention belongs to the technical field of energy conversion, and in particular relates to a method and a device for realizing energy conversion by utilizing the buoyancy and gravity of an air bag. Background Art

[0002] As we all know, when a certain amount of liquid is placed in a container and a balloon is completely immersed in the liquid in the container, the liquid level in the container will rise because the balloon displaces the liquid, and the balloon will also be affected by the strong buoyancy of the water, making the balloon tend to move upward. In addition, when a heavy object is placed at a higher position, gravitational potential energy is generated. When the heavy object is thrown from a high place, the gravitational potential energy of the heavy object is converted into mechanical kinetic energy.

[0003] However, when gravity does work, the airbag moves downward, and when buoyancy does work, the airbag moves upward. According to the normal mechanical installation method, when the airbag drives the chain and then drives the sprocket to rotate, the rotation direction of the sprocket is opposite during the upward and downward movements, and the sprocket cannot rotate continuously in the same direction. How to achieve continuous directional rotation of the output shaft during the rising and falling process of the airbag is a major problem that plagues technicians today.

[0004] If the output shaft cannot achieve continuous directional rotation, it cannot continuously output energy, and cannot achieve continuous energy conversion by doing work through buoyancy and gravity. Summary of the invention

[0005] The purpose of the present invention is to provide a method and device for realizing energy conversion by utilizing the buoyancy and gravity of an airbag, and to solve the technical problem of how to realize continuous energy conversion by utilizing the buoyancy and gravity of the airbag to do work.

[0006] The method for realizing energy conversion by utilizing air bag buoyancy and gravity specifically comprises the following steps:

[0007] After the airbag is inflated, it rises in the liquid, driving the chain to rise. The chain is connected to the output shaft through a one-way rotating mechanism, driving the output shaft to rotate;

[0008] After the airbag is deflated, it descends in the liquid, driving the chain down. The chain is connected to the output shaft through a one-way rotating mechanism, driving the output shaft to rotate in the same direction as when the airbag rises;

[0009] The one-way rotating mechanism connected with the chain is installed in the same direction. When the airbag rises, one set of the one-way rotating mechanism provides power to the output shaft, and the other set of the one-way rotating mechanism idles. When the airbag descends, one set of the one-way rotating mechanism provides power to the output shaft, and the other set of the one-way rotating mechanism idles.

[0010] The airbag repeats the rising and falling process, driving the output shaft to rotate continuously.

[0011] The one-way rotating mechanism is installed in the same direction, which refers to the relative motion relationship between the one-way rotating mechanism and the output shaft. The one-way rotating mechanism can drive the output shaft to rotate only when the one-way rotating mechanism and the output shaft have the same direction of rotation.

[0012] The airbag is provided with a counterweight structure, and the counterweight structure is used to accelerate the descent of the airbag.

[0013] The number of the one-way rotating mechanisms is at least two, and when the airbag rises and falls, at least one of the one-way rotating mechanisms drives the output shaft to rotate;

[0014] During the rising and falling process of the airbag, at least one unidirectional rotating mechanism provides power to the output shaft to drive the output shaft to rotate.

[0015] The forward and reverse installation of the chain and the same-direction installation of the one-way rotation mechanism realize the directional rotation of the output shaft.

[0016] A device for realizing energy conversion by utilizing the buoyancy and gravity of an airbag, comprising an airbag arranged in a liquid holding device, an output shaft, a one-way rotating mechanism arranged on the output shaft, and a supporting assembly, wherein one end of a chain is connected to one end of the airbag, the other end of the chain passes through the one-way rotating mechanism, and the supporting assembly is connected to the other end of the airbag;

[0017] A counterweight structure is arranged on the airbag, and the airbag is connected with an inflation and deflation system.

[0018] The chain has at least two chains, and when viewed along the axial direction of the output shaft, the rotation directions of at least two unidirectional rotating mechanisms are opposite.

[0019] The support assembly includes a plurality of support sprockets arranged in sequence from top to bottom. In the support assembly matched with the same chain, at least one support sprocket is fixed at the bottom of the device.

[0020] The inflation and deflation system includes an inflation pump, a buffer air tank, an air deflation valve and an inflation valve connected to the airbag. The inflation pump, the buffer air tank, the inflation valve, the air deflation valve and the airbag form an air path connected through an air pipe. The inflation and deflation system is used to quickly inflate and deflate the airbag, and the inflation time of the inflation pump is much shorter than the working time of the output shaft.

[0021] The air pipe is provided with a slidable counterweight device to maintain the verticality of the air pipe, achieve synchronous rise with the air bag, prevent the air pipe and the chain from being mixed together, and ensure the normal operation of the device.

[0022] The airbag includes an airbag shell, a central tube disposed in the airbag shell, and a plurality of support bars;

[0023] The central tube is provided with a vent, and the central tube is communicated with the inflation and deflation system.

[0024] A buffer device is arranged between the airbag and the bottom of the device. When the airbag descends to the bottom of the liquid holding device, the buffer device gives the airbag an upward elastic force, and the movement direction of the airbag is changed, thereby protecting the airbag and preventing the airbag from being damaged.

[0025] The volume of the liquid holding device will be different depending on the energy output requirements of the output shaft.

[0026] How this solution works:

[0027] When the airbag is deflated, the airbag is driven by the gravity of the counterweight device (including the airbag's own weight) and its acceleration decreases, driving the output shaft to rotate; during the deflation process, the deflation valve discharges gas, forming a recoil force, which accelerates the descent speed of the airbag;

[0028] When the airbag is inflated, the airbag accelerates due to its own buoyancy (including the buoyancy of the trachea), driving the output shaft to rotate.

[0029] The beneficial effects of the present invention are as follows:

[0030] (1) Place the airbag at the bottom of the device and inflate it. The airbag rises under the action of strong buoyancy and drives the output shaft to rotate through the chain. The buoyancy work is converted into rotational energy of the output shaft. The energy input in this process is the electrical energy consumed by the air pump and the buoyancy work. These two energies are superimposed and the electrical energy consumed by the air pump and the buoyancy work are converted into rotational energy of the output shaft, thus realizing energy conversion.

[0031] (2) When the airbag approaches the top of the device, the deflation valve releases the gas in the airbag. Under the action of the counterweight device, the airbag overcomes the buoyancy and accelerates its descent until it reaches the bottom of the device. The descent of the airbag drives the rotation of the output shaft. In this process, the recoil force generated by the deflation valve, combined with the gravitational work of the airbag and the counterweight device, is converted into the rotational energy of the output shaft. No external energy input is required during the descent process. The recoil force generated by the deflation valve, combined with the gravitational work of the airbag and the counterweight device, is converted into the rotational energy of the output shaft, thereby realizing energy conversion.

[0032] (3) During the continuous up and down movement of the airbag, the output shaft rotates continuously in the same direction under the cooperation of the chain and the one-way rotating mechanism, which has a wide range of applications and usage space, and realizes energy conversion.

[0033] (4) The rising and falling process of the airbag is a stroke. During this stroke, the inflation time of the air pump is much shorter than the working time of the output shaft.

[0034] (5) The deflation valve connected to the airbag not only quickly discharges the air in the airbag, but also the recoil force generated by the deflation of the deflation valve, combined with the gravity work of the airbag and the counterweight device, is converted into rotational energy of the output shaft, thereby realizing energy conversion.

DETAILED DESCRIPTION

[0043] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0044] See also Figure 1-Figure 7 The method of realizing energy conversion by utilizing airbag buoyancy and gravity specifically comprises the following steps:

[0045] After the airbag 9 is inflated, it rises in the liquid, driving the chain to rise. The chain is connected to the output shaft 1 through the one-way rotating mechanism 2, driving the output shaft 1 to rotate;

[0046] After the airbag 9 is deflated, it descends in the liquid, driving the chain down. The chain is connected to the output shaft 1 through the one-way rotating mechanism 2, driving the output shaft 1 to rotate in the same direction as the airbag 9 when it rises;

[0047] The one-way rotating mechanism 2 connected with the chain is installed in the same direction. When the airbag 9 rises, one set of the one-way rotating mechanism 2 provides power to the output shaft 1, and the other set of the one-way rotating mechanism 2 idles. When the airbag 9 descends, one set of the one-way rotating mechanism 2 provides power to the output shaft 1, and the other set of the one-way rotating mechanism 2 idles.

[0048] The airbag 9 repeats the rising and falling process, driving the output shaft 1 to rotate continuously.

[0049] The one-way rotating mechanism 2 is installed in the same direction, which refers to the relative motion relationship between the one-way rotating mechanism 2 and the output shaft 1. The one-way rotating mechanism 2 can drive the output shaft 1 to rotate only when the one-way rotating mechanism 2 and the output shaft 1 have the same direction of rotation.

[0050] A counterweight structure 61 is provided on the airbag 9 , and the counterweight structure 61 is used to accelerate the descent of the airbag 9 .

[0051] The number of the one-way rotating mechanisms 2 is at least two, and when the airbag 9 rises and falls, at least one of the one-way rotating mechanisms 2 drives the output shaft 1 to rotate;

[0052] During the rising and falling process of the airbag 9, at least one unidirectional rotating mechanism 2 provides power to the output shaft 1, driving the output shaft 1 to rotate.

[0053] The forward and reverse installation of the chain and the same-direction installation of the one-way rotating mechanism 2 realize the directional rotation of the output shaft 1.

[0054] A device for realizing energy conversion by utilizing the buoyancy and gravity of an airbag, comprising an airbag 9 arranged in a liquid holding device 17, an output shaft 1, a one-way rotating mechanism 2 arranged on the output shaft 1, and a supporting assembly, wherein one end of a chain is connected to one end of the airbag 9, and the other end of the chain passes through the one-way rotating mechanism 2, and the supporting assembly is connected to the other end of the airbag 9;

[0055] A counterweight structure 61 is provided on the airbag 9, and the airbag 9 is connected to the inflation and deflation system.

[0056] The chain has at least two chains, and when viewed along the axial direction of the output shaft 1 , the rotation directions of at least two unidirectional rotating mechanisms 2 are opposite.

[0057] The support assembly comprises a plurality of support sprockets arranged in sequence from top to bottom. In the support assembly matched with the same chain, at least one support sprocket is fixed at the bottom of the device.

[0058] The inflation and deflation system includes an inflation pump 14, a buffer air tank 15, an air deflation valve and an inflation valve 162 connected to the airbag 9. The inflation pump 14, the buffer air tank 15, the inflation valve 162, the air deflation valve and the airbag 9 form an air path connected through the air pipe 16. The inflation and deflation system is used to quickly inflate and deflate the airbag 9. The inflation time of the inflation pump 14 is much shorter than the working time of the output shaft 1.

[0059] As an embodiment, there are two deflation valves, namely deflation valve one 96 and deflation valve two 97, which are arranged on both sides of the airbag 9. The deflation valve one 96 and the deflation valve two 97 are both connected to the valve controller to automatically control the opening and closing of the valve as needed.

[0060] A slidable counterweight device 161 is provided on the air pipe 16 to maintain the verticality of the air pipe 16, achieve synchronous rise with the air bag 9, prevent the air pipe 16 from being mixed with the chain, and ensure the normal operation of the device.

[0061] The airbag 9 includes an airbag shell, a central tube 92 disposed in the airbag shell, and a plurality of support bars 91;

[0062] A vent is provided on the central tube 92, and the central tube 92 is connected to the inflation and deflation system.

[0063] A buffer device 21 is provided between the airbag 9 and the bottom of the device. When the airbag 9 descends to the bottom near the liquid holding device 17, the buffer device 21 gives the airbag 9 an upward elastic force, and the movement direction of the airbag 9 is changed, thereby protecting the airbag 9 and preventing the airbag 9 from being damaged.

[0064] The specific working process of the present invention is:

[0065] The airbag 9 is placed in the liquid holding device. Under the gravity of the counterweight device 161 and the counterweight structure 61, the airbag 9 sinks to the bottom of the liquid. At this time, the airbag 9 is inflated by the inflation and deflation system. In the actual experiment, the height of the liquid holding device is 13.5m, the diameter is 1.27m, and the volume of the airbag 9 after being filled is 0.465m 3 In less than 1 second, the airbag 9 will be filled with air, and the airbag 9 will accelerate from the bottom to the top in about 3-4 seconds, and the descending time will be about 4-5 seconds.

[0066] Under the action of strong buoyancy, the airbag 9 rises, drives the output shaft 1 to rotate through the chain, and performs work through buoyancy, thereby realizing the effect of converting into mechanical energy.

[0067] Specifically, in the attached drawings, there are two chains connecting the airbag 9, namely the first chain 3 and the second chain 8. One end of the first chain 3 is connected to the top of the airbag 9, and the other end thereof passes through the one-way rotating mechanism 2, the supporting sprocket one 4, and the supporting sprocket two 5, and is connected to the bottom end of the airbag 9. The supporting sprocket one 4 and the supporting sprocket two 5 are respectively fixed to the upper end and the lower end of the liquid holding device; similarly, one end of the second chain 8 is connected to the top of the airbag 9, and the other end thereof passes through the one-way rotating mechanism 2, the supporting sprocket three 7, and the supporting sprocket four 10, and is connected to the bottom end of the airbag 9. The supporting sprocket three 7 and the supporting sprocket four 10 are respectively fixed to the lower end and the upper end of the water body;

[0068] Specifically, the first chain 3 is divided into two regions, a moving part 1 31 and a moving part 2 32, by a one-way rotating mechanism, and their rising and falling states are opposite, while the second chain 8 is divided into two parts, a moving part 3 81 and a moving part 4 82, by a one-way rotating mechanism 9, and their rising and falling states are opposite;

[0069] The unidirectional rotating mechanism 9 has a variety of structural implementation methods, such as a one-way bearing, a ratchet structure connected to a sprocket, etc. In the ratchet structure connected to the sprocket, the ratchet structure rotates clockwise to drive the output shaft to rotate, while if it rotates counterclockwise, the ratchet structure just idles. The first chain 3 and the second chain 8 are respectively connected to different ratchet structures, and the movement directions of the two ratchet structures are always opposite. There are many other mechanisms that can achieve unidirectional rotation, which are all existing technologies and will not be described in detail here.

[0070] When the airbag 9 approaches the top of the liquid holding device, the gas in the airbag 9 is released. At this time, the buoyancy has little effect on the airbag 9. Under the action of the counterweight, the airbag 9 overcomes the smaller buoyancy and moves downward until it reaches the bottom of the liquid holding device. The movement of the airbag 9 also drives the rotation of the output shaft 1. In this process, the gravitational potential energy of the airbag 9, the counterweight device 161, and the counterweight structure 61 is converted into the mechanical energy of the output shaft 1. This process does not involve the consumption of external energy.

[0071] Preferably, a buffer device 21 is provided at the bottom end of the liquid containing device, and an upper limit device 11 and a lower limit device 6 are fixedly provided at the upper and lower ends of the airbag 9 respectively, and the lower limit device 6 is movably abutted against the buffer device 21 to achieve a buffering effect.

[0072] It should be noted that the upper limit device 11 and the lower limit device 6 also play a counterweight effect.

[0073] A counterweight structure 61 is provided in the lower limit device 6 and the upper limit device 11 .

[0074] During the continuous up and down movement of the airbag 9, under the cooperation of the chain and the one-way rotating mechanism 2, the output shaft 1 rotates continuously in the same direction. This phenomenon can be utilized to convert the mechanical energy of the output shaft 1 into other forms of energy, which has a wide range of applications and usage space; for example, a power wheel 121 is arranged on the output shaft 1, and the power wheel 121 is connected to the power wheel 2 13 through the power chain 12, and the power wheel 2 13 can be coaxially connected to a mechanical mechanism or an electric energy generating device that requires a driving force.

[0075] When the device is actually used, a spiral staircase 18 is provided on the outside of the liquid containing device 17 for technicians to climb up and down, and a bracket 19 is provided at the top of the liquid containing device 17. The top of the bracket 19 is a guardrail 20, and inside the guardrail 20 is a mechanical mechanism or electric energy generating device requiring driving force.

[0076] Technical features not described in the present invention can be achieved through or by adopting existing technologies and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the scope of protection of the present invention.
