Description

Technical Field

[0001] The present application relates to the field of gravity energy storage, and in particular to a circulation system with stable output for gravity energy storage. Background Art

[0002] Gravity energy storage is a method of storing energy using gravitational potential energy. The basic principle is to store energy by lifting gravity power generation blocks to a high place. When the energy needs to be released, these gravity power generation blocks are lowered to drive the generator to generate electricity.

[0003] Existing gravity energy storage devices have the following problems: 1. Sudden change in driving force. In the prior art, the loading and unloading of heavy objects are discrete events, that is, they are suddenly mounted or detached from the bearing mechanism at a certain moment, resulting in a sudden change in the driving force on the bearing mechanism, which in turn leads to a reduction in the fatigue life of the mechanical system; 2. Discontinuous operation. The loading and unloading of heavy objects usually requires the system to suspend operation to complete the mechanical operation, which reduces the continuous operation capability and overall efficiency of the system; 3. Unstable output power. Due to the asynchronous loading and unloading of heavy objects, the driving force fluctuates, which in turn leads to unstable output power.

DETAILED DESCRIPTION

[0021] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0022] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the application is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0023] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of the embodiments of the present application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] According to the present invention, a circulation system with stable output for gravity energy storage is provided, such as Figures 1 to 8 As shown, the gravity energy storage circulation system with stable output can generate electricity stably, and the gravity energy storage circulation system with stable output includes a connection system and a bearing mechanism 2. It should be noted here that gravity energy storage actually includes the energy storage process of transporting the following heavy block 1 from a low place to a high place and the power generation process of transporting the following heavy block 1 from a high place to a low place. The gravity energy storage circulation system with stable output can achieve stable output power generation during the power generation process. As for the energy storage process, the device in the prior art can be used to transport the heavy block 1 from a low place to a high place, which will not be repeated here.

[0026] In the following description, reference will be made to Figures 1 to 8 The detailed structure of the connection system and the supporting mechanism 2 of the circulation system with stable output for gravity energy storage will be described in detail.

[0027] like Figure 1 and Figure 3 As shown, in the embodiment, the connection system can be understood as a transfer system composed of a rotating wheel and a connection member, and the transfer system can transport the carrying mechanism 2 from a high place to a low place. During the process of transporting the carrying mechanism 2 from a high place to a low place, the heavy object block 1 can be located inside the carrying mechanism 2, and the transfer system can also transport the carrying mechanism 2 from a low place back to a high place to realize the reflux of the carrying mechanism 2.

[0028] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, in the embodiment, the bearing mechanism 2 can be a device with an internal accommodation space made of metal materials such as iron or steel. Since the weight block 1 is formed as a rectangular parallelepiped structure in the embodiment, the accommodation space of the bearing mechanism 2 can also be formed as a rectangular parallelepiped shape. However, it is not limited to this. The bearing mechanism 2 can be a component in the prior art, and its structure, shape, and material, etc. can be known to those skilled in the art, and no additional details are given here. The difference is that the bearing mechanism 2 in the embodiment can be connected to the above-mentioned connection system through a conversion mechanism.

[0029] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in the embodiment, the connection system includes a transition connection module, an output connection module and a conversion track module 7. The carrying mechanism 2 can follow the conversion track module 7 to switch between the transition connection module and the output connection module.

[0030] Specifically, see Figure 5 and Figure 6 The conversion mechanism is movably disposed on the supporting mechanism 2. In the embodiment, the conversion mechanism is disposed on both sides of the supporting mechanism 2 so that both sides of the supporting mechanism 2 can be connected to the connection system. A waist-shaped hole 306 for moving the conversion mechanism is provided at the connection between the conversion mechanism and the supporting mechanism 2, and the end of the conversion mechanism can be movably clamped in the inside of the waist-shaped hole 306 (the movably clamped arrangement can be, for example: a sliding track is provided inside the waist-shaped hole 306, and the size of the end of the conversion mechanism is larger than the size of the waist-shaped hole 306, and can be docked with the sliding track, so that the end of the conversion mechanism can be clamped in the waist-shaped hole 306 and can move on the waist-shaped hole 306), and a reset spring is provided inside the waist-shaped hole 306 (due to angle reasons, not shown, one end of the reset spring is fixedly connected to the inner wall of the waist-shaped hole 306, and the other end is fixedly connected to the end of the conversion mechanism). In this way, when the conversion mechanism is driven by an external force, the conversion mechanism can be moved along the waist-shaped hole 306, thereby changing the relative position of the conversion mechanism and the supporting mechanism 2. When the external force is cancelled, the conversion mechanism is affected by the spring force and can be reset.

[0031] Further, see Figure 4 and Figure 5, the conversion mechanism may include a transition portion and an output portion 303 connected to each other, and the connection between the transition portion and the output portion 303 may be, for example, by using a connecting rod 305. The transition portion is provided with a pulley member 304, and the transition portion is slidably connected to the conversion track module 7 through the pulley member 304. The pulley member 304 moves along the conversion track module 7 to change the position so that the conversion mechanism changes its position on the carrier mechanism 2, thereby connecting the transition portion to the transition connection module or the output portion 303 to the output connection module. The conversion track module 7 is not a vertical track, but includes an inclined track and a vertical track. In this way, the position of the conversion track module 7 at different heights is different, and different external forces can be applied to the conversion mechanism, that is, the external force of "the conversion mechanism is driven by the external force" mentioned above is applied by the conversion track module 7. In this way, by driving the conversion mechanism to change its position through the conversion track module 7, the carrier mechanism 2 (the carrier mechanism 2 carries the heavy object block 1) can be connected to the transition connection module or the output connection module at different positions during the movement from a high place to a low place.

[0032] The principle of this design is that when the existing gravity energy storage system generates electricity, the loading and unloading of the weight block 1 is a discrete event, that is, it is suddenly mounted on the carrying mechanism 2 or suddenly detached from the carrying mechanism 2 at a certain moment, resulting in a sudden change in the driving force on the carrying mechanism 2, which in turn leads to unstable and continuous power generation and reduces the fatigue life of the mechanical system. Then, in order to avoid sudden changes in the driving force and make the mounting or detachment of the weight block 1 a continuous event, a transition connection module is required to perform a "transition", that is, loading and unloading are performed through the transition connection module, and power generation is achieved through the output connection module.

[0033] Based on this, the core design principle of the circulation system with stable output for gravity energy storage is that: when loading, the transition connection module is used to bear the instantaneous bearing capacity of the heavy object block 1 entering the bearing mechanism 2. After bearing, through the cooperation of the conversion track module 7 and the conversion mechanism, the bearing mechanism 2 carrying the heavy object block 1 is continuously and stably transitioned to the output connection module. At this time, the output connection module will not be affected by the sudden change in bearing capacity, and the output power quality can be guaranteed to be high, and the output power is stable without causing fluctuations. In addition, the output connection module can be connected to an external generator, and the power generation parts such as rotating wheels are driven by the output connection module, so that the generator generates electricity. The power generation part can adopt the means in the prior art, which is known to those skilled in the art, so it will not be repeated here. When unloading, the bearing mechanism 2 carrying the heavy object block 1 is continuously and stably transitioned from the output connection module to the transition connection module through the cooperation of the conversion track module 7 and the conversion mechanism.

[0034] The "transition" process is not completed in an instant, but is achieved continuously and stably through the track of the conversion track module 7. That is, it can be understood that the conversion mechanism slides on the supporting mechanism 2. During the sliding process, it detaches from the transition connection module and connects with the output connection module; or detaches from the output connection module and connects with the transition connection module.

[0035] The gravity energy storage output stable circulation system is achieved through the cooperation of the connection system and the supporting mechanism 2, so that the system can achieve continuous and stable power generation; through the cooperation of the transition connection module, the output connection module, the conversion track module 7 and the conversion mechanism, the loading and unloading of the heavy block 1 are formed into continuous events, thereby avoiding sudden changes in the driving force on the supporting mechanism 2, making the output power more stable while improving the fatigue life of the mechanical system; since loading and unloading are completed on the transition connection module, the output connection module does not need to suspend operation during loading and unloading, which improves the continuous operation capability and overall efficiency of the system and ensures the stability of the output power of the entire system.

[0036] Preferably, in an embodiment, when the output stable circulation system for gravity energy storage is in operation, that is, during power generation, the output connection module is in a uniform rotation state, and the transition connection module is in a speed regulation state. The driving force for the uniform motion of the output connection module can be driven by the first weight block 1 through the gravitational potential energy or driven by an external motor so that the output connection module is in a uniform speed state at the beginning. The transition connection module is driven by an external motor (not shown) so that the speed of the transition connection module can be increased from zero to the same as the speed of the output connection module, and then decelerated to zero.

[0037] The purpose of this design is that since the output connection module is always in uniform motion, the electric energy output by the output connection module can always be stably output without fluctuations during the process of power generation by the gravity energy storage circulation system with stable output. When the transition connection module is loaded with the heavy block 1, its speed is zero, which can effectively reduce the instantaneous bearing capacity of the heavy block 1 entering the bearing mechanism 2, and then gradually accelerate to the same speed as the output connection module. The bearing mechanism 2 is driven by the conversion mechanism to continuously transition from the transition connection module to the output connection module. During unloading, the speed of the transition connection module is the same as that of the output connection module (it can be understood that when the speed of the transition connection module is the same as that of the output connection module, the speed of the transition connection module is at Figure 1 The upper center load transfers the weight block 1 to the output connection module, located at Figure 1The unloading at the lower middle part transfers the heavy object block 1 to the transition connection module, that is, loading and unloading can be carried out simultaneously). The carrying mechanism 2 loaded with the heavy object block 1 is continuously transferred back from the output connection module to the transition connection module through the conversion mechanism at a uniform speed. During the transfer process, the speed of the transition connection module gradually decelerates to zero. When the speed reaches zero, the heavy object block 1 is transported out by the transportation device (not shown) at the bottom.

[0038] In addition, whether the heavy object block 1 is transported to the carrying mechanism 2 at the loading position or the heavy object block 1 is transported out at the unloading position, it can be achieved through a transportation device. The transportation device can be a conveyor belt device in the prior art. Its structure and arrangement are known to technicians in this field and will not be repeated here.

[0039] Preferably, if Figure 2 , Figure 3 and Figure 4 As shown, in an embodiment, the transition connection module may include a first connection component 4, the first connection component 4 may include a first connection member 401, a first rotating wheel 402 and a second rotating wheel 403, the first rotating wheel 402 and the second rotating wheel 403 are relatively arranged at the top and bottom of the connection system, the first connection member 401 surrounds the first rotating wheel 402 and the second rotating wheel 403, and the first connection member 401 passes through the end of the transition part. The output connection module may include a second connection component 5, the second connection component 5 includes a second connection member 501, a third rotating wheel 502 and a fourth rotating wheel 503, the third rotating wheel 502 and the fourth rotating wheel 503 are relatively arranged at the top and bottom of the connection system, the second connection member 501 surrounds the third rotating wheel 502 and the fourth rotating wheel 503, and the second connection member 501 passes through the end of the output part 303. The first connection member 401 and the second connection member 501 may both be steel cables, and the steel cables surround the rotating wheels to form a connection system. During the operation of the entire system, the second connecting member 501, the third rotating wheel 502 and the fourth rotating wheel 503 are always in a uniform motion state. The first connecting member 401, the first rotating wheel 402 and the second rotating wheel 403 are driven by an external motor, and the speed increases from zero to the same speed as the second connecting component 5, and then decelerates to zero. The external motor can directly drive the first rotating wheel 402 or the second rotating wheel 403. In this way, the supporting mechanism 2 is connected to the first connecting member 401 or the second connecting member 501 through the transition part and the output part 303 of the conversion mechanism.

[0040] Preferably, if Figure 2 , Figure 3 and Figure 4As shown, in the embodiment, in order to realize the circulation of the supporting mechanism 2, that is, to transport the unloaded supporting mechanism 2 from the bottom to the top of the entire system, the transition connection module also includes a third connection assembly 6, and the third connection assembly 6 includes a third connecting member 601, a fifth rotating wheel 602, a sixth rotating wheel 603, a seventh rotating wheel 604 and an eighth rotating wheel 605. The fifth rotating wheel 602, the sixth rotating wheel 603, the seventh rotating wheel 604 and the eighth rotating wheel 605 are arranged opposite to each other at the top and the bottom of the connection system, and the third connecting member 601 surrounds the fifth rotating wheel 602, the sixth rotating wheel 603, the seventh rotating wheel 604 and the eighth rotating wheel 605.

[0041] The first connecting component 4 and the second connecting component 5 are arranged inside the area formed by the third connecting member 601 around the fifth rotating wheel 602, the sixth rotating wheel 603, the seventh rotating wheel 604 and the eighth rotating wheel 605. In addition, no matter what the case, the speed of the first connecting component 4 and the speed of the third connecting component 6 are the same, that is, the two are accelerated together, accelerated to the same speed as the second connecting component 5, and then decelerated together to zero. The third connecting component 6 can also be driven by an external motor, or an external motor drives the first connecting component 4 and the third connecting component 6 at the same time. The motor driving method is a common technology and will not be repeated here.

[0042] exist Figure 4 In the figure, the supporting mechanism 2 on the right side is loaded with the weight block 1 to realize power generation, while the supporting mechanism 2 on the left side is unloaded and refluxed. When generating electricity, the left and right ends of the supporting mechanism 2 are first connected to the first connecting member 401 and the third connecting member 601 respectively through the transition part. After carrying the weight block 1, the supporting mechanism 2 moves downward, and the pulley member 304 of the conversion mechanism moves along the conversion track module 7, and the relative position of the conversion mechanism and the supporting mechanism 2 changes, so that the transition part of the conversion mechanism is gradually separated from the first connecting member 401 and the third connecting member 601, and the output part 303 is gradually connected to the second connecting member 501 to generate electricity. After the gravitational potential energy of the weight block 1 is gradually exhausted, the pulley member 304 of the conversion mechanism moves and changes its position along the conversion track module 7, and the relative position of the conversion mechanism and the supporting mechanism 2 is changed again (reset), so that the transition part of the conversion mechanism is gradually connected to the first connecting member 401 and the third connecting member 601, and the output part 303 is gradually separated from the second connecting member 501. After unloading the weight block 1, as shown in Figure 3As shown in the lower part of the figure, the output part 303 of the supporting mechanism 2 is separated from the second connecting member 501 and is no longer connected to the second connecting assembly 5. The transition part of the supporting mechanism 2 flows back to the top of the connecting system through the second rotating wheel 403, the seventh rotating wheel 604 and the eighth rotating wheel 605, and then returns to the original position through the first rotating wheel 402, the fifth rotating wheel 602 and the sixth rotating wheel 603. At this time, the output part 303 contacts the second connecting member 501 again. It should be noted that the above-mentioned "the output part 303 is gradually separated from or connected to the second connecting member 501" and "the transition part is separated from or connected to the first connecting member 401 and the third connecting member 601" do not mean complete separation. Only when the supporting mechanism 2 flows back, the output part 303 is completely separated from the second connecting member 501. Separation refers to the change from surface contact to point contact. On the one hand, even if the first connecting member 401 and the third connecting member 601 do not provide driving force, they can still play the role of limiting and supporting to ensure the stability of the posture of the supporting mechanism 2 during the movement. On the other hand, it is also convenient for the supporting mechanism 2 to smoothly realize position changes.

[0043] Preferably, if Figure 4 As shown, in the embodiment, in order to ensure that the supporting mechanism 2 avoids interference during reflow, the second connecting member 501 is arranged between the first connecting member 401 and the third connecting member 601 .

[0044] Preferably, if Figure 2 , Figures 3 to 6 As shown, in the embodiment, in order to correspond to the above-mentioned first connecting member 401 and the third connecting member 601, the transition part includes a first transition member 301 and a second transition member 302, the first connecting member 401 passes through the end of the first transition member 301, and the third connecting member 601 passes through the end of the second transition member 302.

[0045] Preferably, if Figure 5 As shown, in the embodiment, the end of the output part 303, the end of the first transition piece 301 and the end of the second transition piece 302 are all formed with a notch, that is, the ends of the three are all formed into a structure approximately in the shape of a letter C. The opening direction of the notch at the end of the output part 303 is opposite to the opening direction of the notch at the end of the first transition piece 301 and the opening direction of the notch at the end of the second transition piece 302. The opposite opening directions of the notches can make it possible that when the conversion mechanism moves, the output part 303 is connected to the second connecting piece 501, and the first transition piece 301 and the second transition piece 302 are separated from the first connecting piece 401 and the third connecting piece 601, or the output part 303 is separated from the second connecting piece 501, and the first transition piece 301 and the second transition piece 302 are connected to the first connecting piece 401 and the third connecting piece 601.

[0046] Furthermore, in order to achieve a stable transition between connection and separation, the end of the C-shape may be made of a soft material, such as soft polyurethane. Still further, in order to increase the contact force, the inner wall of the C-shape is provided with a zigzag pattern.

[0047] Preferably, if Figure 7 and Figure 8 As shown, in the embodiment, the conversion track module 7 may include a connection track 701, a transition track 702 and an output track 703. The connection track 701 is connected to the output track 703 through the transition track 702. The connection track 701 is close to the transition connection module, and the output track 703 is close to the output connection module. The connection track 701 and the output track 703 are both formed as vertical tracks, and the transition track 702 is formed as an inclined track. Figure 4 In the relative position shown, the connecting track 701 is close to the first connecting member 401, and the output track 703 is close to the second connecting member 501. When the pulley member 304 slides on the connecting track 701, the conversion mechanism as a whole is in Figure 4 The left side of Figure 5 In the C-shape, it can be understood that the first transition member 301 and the second transition member 302 clamp the first connecting member 401 and the third connecting member 601. When the pulley member 304 slides toward the output track 703 through the transition track 702, the conversion mechanism continuously moves to Figure 4 The right side of the transition connection module is transferred until the pulley member 304 slides to the output track 703. At this time, the output portion 303 clamps the second connecting member 501, completing the continuous and smooth transfer of the supporting mechanism 2 from the transition connection module to the output connection module.

[0048] Preferably, if Figure 7 and Figure 8 As shown, in the embodiment, the conversion track module 7 is formed into a symmetrical structure, that is, a vertically symmetrical structure. Then, when unloading, the pulley member 304 slides on the output track 703, and the conversion mechanism is in Figure 4 In the right side. Combine Figure 5 In the C-shape, it can be understood that at this time, the output part 303 clamps the second connecting member 501, and when the pulley member 304 slides toward the connecting track 701 through the transition track 702, the conversion mechanism continuously moves to Figure 4 The transfer is performed to the left side of the output connection module until the pulley 304 slides to the connection track 701. The first transition member 301 and the second transition member 302 clamp the first connection member 401 and the third connection member 601 at this time, completing the continuous and smooth transfer of the carrying mechanism 2 from the output connection module to the transition connection module. When the carrying mechanism 2 is reflowed, no matter what position the conversion mechanism is in, it is driven by the reset spring to achieve reset, so as to ensure that the pulley 304 directly docks with the connection track 701 at the beginning of the next cycle.

[0049] Preferably, if Figure 1 and Figure 2 As shown, in the embodiment, in order to ensure the stable movement of the supporting mechanism 2, the circulation system with stable output for gravity energy storage includes two connection systems arranged symmetrically to each other, and the two connection systems are respectively arranged at two ends of the supporting mechanism 2.

[0050] Preferably, if Figures 1 to 4 As shown, in an embodiment, the circulation system with stable output for gravity energy storage may further include a stabilizing module, which may include a stabilizing track 801, which is arranged on the reference plane 9. In order to make the power generation process of the entire system more stable, a stabilizing track 801 is additionally installed, and the stabilizing track 801 may be installed on the reference plane 9, which may be, for example, a side of a mountain or a building facing the gravity energy storage system, and this reference plane 9 may be a vertical plane. In order to further ensure the stability of the movement of the bearing mechanism 2, a stabilizing pulley 802 is also arranged at the end of the bearing mechanism 2, and the bearing mechanism 2 is slidably connected to the stabilizing track 801 through the stabilizing pulley 802.

[0051] The operation process of the gravity energy storage output stable circulation system is as follows: Figure 4, the heavy object block 1 is transmitted to a carrying mechanism 2 via the preceding conveyor belt. After the heavy object block 1 is loaded on the carrying mechanism 2, it is affected by gravity and moves downward. At this time: 1. The carrying mechanism 2 is slidably connected to the stabilizing track 801 via the stabilizing pulley 802 to ensure the sliding stability of the carrying mechanism 2; 2. The second connecting member 501 always maintains uniform motion; 3. At this time, the carrying mechanism 2 is connected to the first connecting member 401 and the third connecting member 601 via the first transition member 301 and the second transition member 302 of the conversion mechanism (it can also be understood that at this time, the pulley member 304 on the first transition member 301 is limited by the connecting track 701 of the conversion track module 7, so that The end of the first transition piece 301 and the end of the second transition piece 302 clamp the first connection piece 401 and the third connection piece 601); Fourth, the first connection piece 401 and the third connection piece 601 are driven by the external motor to gradually accelerate from zero speed to the same speed as the second connection piece 501. During the acceleration process, the pulley 304 slides along the connecting track 701, the transition track 702 and the output track 703 in sequence. When sliding to the output track 703, the output part 303 clamps the second connection piece 501, completing the continuous transition of the bearing mechanism 2 from the first connection piece 401 and the third connection piece 601 to the second connection piece 501. After the transition, the weight block 1 can make the second connection piece 501 continue to maintain uniform motion and convert the gravitational potential energy into electrical energy. After the gravitational potential energy of the weight block 1 is gradually exhausted, the pulley member 304 of the conversion mechanism moves and changes position along the output track 703, the transition track 702 and the connection track 701, and the relative position of the conversion mechanism and the carrying mechanism 2 changes again (resets). At this time, the speed of the first connecting member 401 and the speed of the third connecting member 601 are the same as the speed of the second connecting member 501; the end of the first transition member 301 and the end of the second transition member 302 of the conversion mechanism gradually clamp the first connecting member 401 and the third connecting member 601, and the output part 303 gradually separates from the second connecting member 501. The speed of the first connecting member 401 and the speed of the third connecting member 601 gradually decrease to zero, and the weight block 1 is unloaded. In addition, in order to improve efficiency and save energy, when unloading the weight block 1, the speed of the first connecting member 401 and the speed of the third connecting member 601 gradually decrease to zero, and the weight block 1 can be loaded on the top at the same time. During the operation of the entire system, the conversion of the carrying mechanism 2 carrying the weight block 1 is always continuous and stable.

[0052] After unloading the weight block 1, Figure 3 As shown in the lower part of the figure, the output portion 303 of the support mechanism 2 is separated from the second connection member 501 and is no longer connected to the second connection component 5. The support mechanism 2 is driven by the first connection component 4 and the third connection component 6 to flow back to the top of the connection system and return to the initial position. At this time, the output portion 303 contacts the second connection member 501 again.

[0053] The gravity energy storage output stable circulation system achieves continuous and stable power generation through the cooperation of the connection system and the bearing mechanism; the loading and unloading of the heavy blocks are formed into continuous events through the cooperation of the transition connection module, the output connection module, the conversion track module and the conversion mechanism, thereby avoiding sudden changes in the driving force on the bearing mechanism, making the output power more stable while improving the fatigue life of the mechanical system; since the loading and unloading are completed on the transition connection module, the output connection module does not need to suspend operation during loading and unloading, which improves the continuous operation capability and overall efficiency of the system and ensures the stability of the output power of the entire system.
