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. Its basic principle is to store energy by lifting gravity power generation blocks to a high place. When energy needs to be released, these gravity power generation blocks are then lowered to drive a generator to generate electricity.

[0003] Existing gravity energy storage devices have the following problems: First, the driving force mutates. In the prior art, the loading and unloading of heavy object blocks are discrete events, that is, at a certain moment, they are suddenly mounted or detached from the bearing mechanism, resulting in a sudden change in the driving force on the bearing mechanism, and further leading to a reduction in the fatigue life of the mechanical system. Second, the operation is discontinuous. The loading and unloading of heavy object blocks usually require the system to pause operation to complete mechanical operations, which reduces the continuous operation ability and overall efficiency of the system. Third, the output power is unstable. Due to the asynchronous loading and unloading of heavy object blocks, the driving force fluctuates, which in turn leads to unstable output power.

[0004] Therefore, it is necessary to design a circulation system with stable output for gravity energy storage to solve the above problems. Summary of the Invention

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Usually, the components of the embodiments of the present application described and shown in the accompanying 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 accompanying drawings is not intended to limit the scope of the present application claimed, 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 creative efforts belong to the scope of protection of the present application.

[0029] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this application is usually placed when in use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0030] In addition, terms such as "horizontal" and "vertical" do not require the components to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0031] In the description of the embodiments of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "installed", "connected", and "coupled" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0032] According to a cyclic system with stable output for gravitational energy storage provided by the present invention, as Figures 1 to 8 shown, the cyclic system with stable output for gravitational energy storage can generate electricity stably. The cyclic system with stable output for gravitational energy storage includes a connection system and a bearing mechanism 2. Here, it should be noted that gravitational energy storage actually includes an energy storage process of transporting the following heavy object block 1 from a low place to a high place and a power generation process of transporting the following heavy object block 1 from a high place to a low place. The cyclic system with stable output for gravitational energy storage can achieve stable power generation during the power generation process. As for the energy storage process, devices in the prior art can be used to transport the heavy object block 1 from a low place to a high place, which will not be elaborated here.

[0033] In the following description, reference will be made to Figures 1 to 8 specifically describe the detailed structures of the connection system and the bearing mechanism 2 of the cyclic system with stable output for gravitational energy storage.

[0034] As Figure 1 and Figure 3 shown, in the embodiment, the connection system can be understood as a transfer system composed of a runner and a connecting member. The transfer system can transport the bearing mechanism 2 from a high place to a low place. During the process of transporting the bearing mechanism 2 from a high place to a low place, the heavy object block 1 can be located inside the bearing mechanism 2. The transfer system can also transport the bearing mechanism 2 from a low place back to a high place to realize the return flow of the bearing mechanism 2.

[0035] As Figure 1 、 Figure 3 、 Figure 5 and Figure 6As shown, in the embodiment, the bearing mechanism 2 can be a device with an accommodation space inside, made of a metal material such as iron or steel. Since the heavy object block 1 is formed into a cuboid structure in the embodiment, the accommodation space of the bearing mechanism 2 can also be formed into a cuboid shape. However, it is not limited thereto. The bearing mechanism 2 can be a component in the prior art, and its structure, shape, and manufacturing material can all be known to those skilled in the art, so no additional description will be given here. The difference lies in that: the bearing mechanism 2 in the embodiment can be connected to the above connection system through a conversion mechanism.

[0036] As Figure 1 , Figure 3 , Figure 5 and Figure 6 shown, in the embodiment, the connection system includes a transition connection module, an output connection module, and a conversion track module 7. The bearing mechanism 2 can follow the conversion track module 7 to switch between the transition connection module and the output connection module.

[0037] Specifically, referring to Figure 5 and Figure 6 , the conversion mechanism is movably arranged on the bearing mechanism 2. In the embodiment, the conversion mechanism is arranged on both sides of the bearing mechanism 2 so that both sides of the bearing mechanism 2 can access the connection system. A kidney-shaped hole 306 for the movement of the conversion mechanism is opened at the connection between the conversion mechanism and the bearing mechanism 2. The end of the conversion mechanism is movably clamped inside the kidney-shaped hole 306 (the movable clamping can be, for example, a sliding track is arranged inside the kidney-shaped hole 306, the size of the end of the conversion mechanism is larger than the size of the kidney-shaped hole 306, and it can be docked with the sliding track so that the end of the conversion mechanism can be clamped in the kidney-shaped hole 306 and can also move on the kidney-shaped hole 306), and a return spring is arranged inside the kidney-shaped hole 306 (not shown due to the angle, one end of the return spring is fixedly connected to the inner wall of the kidney-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 move along the kidney-shaped hole 306, thereby changing the relative position between the conversion mechanism and the bearing mechanism 2. When the external force is cancelled, the conversion mechanism is affected by the spring force and can be reset.

[0038] Furthermore, referring to 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.

[0039] 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.

[0040] 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.

[0041] The "transition" process is not completed instantaneously, but is achieved continuously and stably through the orbit of the conversion orbit module 7. That is, it can be understood that the conversion mechanism slides on the bearing mechanism 2. During the sliding process, it detaches from the transition connection module and connects to the output connection module; or detaches from the output connection module and connects to the transition connection module.

[0042] Through the cooperation of the connection system and the bearing mechanism 2, the output-stable cycle system for gravity energy storage enables the system to generate electricity continuously and stably; through the cooperation of the transition connection module, the output connection module, the conversion orbit module 7 and the conversion mechanism, the loading and unloading of the heavy object block 1 become continuous events, thereby avoiding sudden changes in the driving force on the bearing mechanism 2, making the output power more stable while increasing 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 pause during loading and unloading, improving the continuous operation ability and overall efficiency of the system, and ensuring the stability of the output power of the entire system.

[0043] Preferably, in the embodiment, when the output-stable cycle system for gravity energy storage is in an operating state, that is, during the power generation process, 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 realized by the first heavy object block 1 driving through gravitational potential energy or by an external motor driving so that the output connection module is in a uniform 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 increase from zero to the same as the speed of the output connection module and then decelerate to zero.

[0044] The purpose of such a design is that: since the output connection module is always in uniform motion, during the power generation process of the output-stable cycle system for gravity energy storage, the electric energy output through the output connection module can always be stably output without fluctuations. When the transition connection module loads the heavy object block 1, the speed is zero, which can effectively reduce the bearing capacity at the moment when the heavy object block 1 enters the bearing mechanism 2, and then gradually accelerates to the same speed as the output connection module. The bearing mechanism 2 is continuously transitioned from the transition connection module to the output connection module through the drive of the conversion mechanism. During unloading, at this time, the speed of the transition connection module is the same as the speed of the output connection module (it can be understood that: when the speeds of the transition connection module and the output connection module are the same, the loading located Figure 1 above in Figure 1The unloading at the lower middle position transfers the heavy object block 1 to the transition connection module, that is, the loading and unloading can be carried out synchronously). The bearing mechanism 2 loaded with the heavy object block 1 continuously returns from the output connection module to the transition connection module through the conversion mechanism at a constant speed. During the return 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 transport device (not shown) at the bottom.

[0045] In addition, whether the heavy object block 1 is transported to the bearing mechanism 2 at the loading position or the heavy object block 1 is transported out at the unloading position, it can be realized by the transport device. The transport device can be a conveyor belt device in the prior art, and its structure and arrangement manner are well known to those skilled in the art, so details are not described here.

[0046] Preferably, as Figure 2 、 Figure 3 and Figure 4 shown, in the embodiment, the transition connection module may include a first connection component 4. The first connection component 4 may include a first connecting member 401, a first runner 402 and a second runner 403. The first runner 402 and the second runner 403 are relatively arranged at the top and bottom of the connection system. The first connecting member 401 surrounds the first runner 402 and the second runner 403, and the first connecting member 401 penetrates the end of the transition portion. The output connection module may include a second connection component 5. The second connection component 5 includes a second connecting member 501, a third runner 502 and a fourth runner 503. The third runner 502 and the fourth runner 503 are relatively arranged at the top and bottom of the connection system. The second connecting member 501 surrounds the third runner 502 and the fourth runner 503, and the second connecting member 501 penetrates the end of the output portion 303. The first connecting member 401 and the second connecting member 501 may both be steel cable members, and the steel cable members surround the runners to form a connection system. During the operation of the entire system, the second connecting member 501, the third runner 502 and the fourth runner 503 are always in a uniform motion state. While the first connecting member 401, the first runner 402 and the second runner 403 are driven by an external motor, and the speed increases from zero to the same as the speed of the second connection component 5 and then decelerates to zero. The external motor can directly drive the first runner 402 or the second runner 403. In this way, the bearing mechanism 2 is connected to the first connecting member 401 or the second connecting member 501 through the transition portion and the output portion 303 of the conversion mechanism.

[0047] Preferably, as Figure 2 、 Figure 3 and Figure 4As shown, in the embodiment, in order to realize the circulation of the carrying mechanism 2, that is, to transport the empty carrying mechanism 2 from the bottom of the entire system back to the top, the transition connection module further includes a third connection component 6. The third connection component 6 includes a third connecting piece 601, a fifth runner 602, a sixth runner 603, a seventh runner 604, and an eighth runner 605. The fifth runner 602, the sixth runner 603, the seventh runner 604, and the eighth runner 605 are arranged in pairs opposite to each other at the top and bottom of the connection system. The third connecting piece 601 surrounds the fifth runner 602, the sixth runner 603, the seventh runner 604, and the eighth runner 605.

[0048] The first connection component 4 and the second connection component 5 are arranged inside the area formed by the third connecting piece 601 surrounding the fifth runner 602, the sixth runner 603, the seventh runner 604, and the eighth runner 605. In addition, in any case, the speeds of the first connection component 4 and the third connection component 6 are the same, that is, the two accelerate together, accelerate to the same speed as the second connection component 5, and then decelerate to zero together. The third connection component 6 can also be driven by an external motor, or an external motor drives the first connection component 4 and the third connection component 6 at the same time. The motor driving method is a common technology and will not be elaborated here.

[0049] In Figure 4 it, the carrying mechanism 2 on the right side is loaded with heavy blocks 1 to generate electricity, while the carrying mechanism 2 on the left side returns empty. During power generation, the left and right ends of the carrying mechanism 2 are first connected to the first connecting piece 401 and the third connecting piece 601 respectively through the transition part. After carrying the heavy block 1, the carrying mechanism 2 moves downward. The pulley member 304 of the conversion mechanism moves along the conversion track module 7, and the relative position between the conversion mechanism and the carrying mechanism 2 changes, so that the transition part of the conversion mechanism gradually separates from the first connecting piece 401 and the third connecting piece 601, and the output part 303 gradually connects to the second connecting piece 501 to generate electricity. After the gravitational potential energy of the heavy block 1 is gradually exhausted, the pulley member 304 of the conversion mechanism moves along the conversion track module 7 to change its position, and the relative position between the conversion mechanism and the carrying mechanism 2 changes again (resets), so that the transition part of the conversion mechanism gradually connects to the first connecting piece 401 and the third connecting piece 601, and the output part 303 gradually separates from the second connecting piece 501. After unloading the heavy block 1, as Figure 3As shown in the lower part of , the output part 303 of the carrying mechanism 2 is disengaged from the second connecting member 501 and no longer connected to the second connecting assembly 5. The transition part of the carrying mechanism 2 returns to the top of the connecting system through the second runner 403, the seventh runner 604 and the eighth runner 605, and then returns to the original position through the first runner 402, the fifth runner 602 and the sixth runner 603. At this time, the output part 303 contacts the second connecting member 501 again. It should be noted that the statements "the output part 303 gradually separates from or connects to the second connecting member 501" and "the transition part separates from or connects to the first connecting member 401 and the third connecting member 601" mentioned above are not complete disconnections. Only when the carrying mechanism 2 returns, the output part 303 is completely disengaged from the second connecting member 501. Separation means that the form of surface contact changes 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 also play a role in limiting and supporting, ensuring the stable posture of the carrying mechanism 2 during movement. On the other hand, it is also convenient for the carrying mechanism 2 to smoothly achieve position changes.

[0050] Preferably, as Figure 4 shown, in the embodiment, in order to ensure that the carrying mechanism 2 avoids interference during return, the second connecting member 501 is arranged between the first connecting member 401 and the third connecting member 601.

[0051] Preferably, as Figure 2 、 Figures 3 to 6 shown, in the embodiment, in order to correspond to the 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.

[0052] Preferably, as Figure 5 shown, in the embodiment, notches are formed at the ends of the output part 303, the first transition member 301 and the second transition member 302, that is, the ends of these three are all formed into a structure approximately in the shape of a 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 member 301 and the opening direction of the notch at the end of the second transition member 302. The opposite opening directions of the notches can make it so that when the conversion mechanism moves, if the output part 303 is connected to the second connecting member 501, then the first transition member 301 and the second transition member 302 are separated from the first connecting member 401 and the third connecting member 601, or if the output part 303 is separated from the second connecting member 501, then the first transition member 301 and the second transition member 302 are connected to the first connecting member 401 and the third connecting member 601.

[0053] 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.

[0054] 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.

[0055] 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 load-carrying mechanism 2 is transferred 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 load-carrying mechanism 2 from the output connection module to the transition connection module. When the load-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.

[0056] Preferably, ifFigure 1 and Figure 2 As shown in Figure 2 , in the embodiment, in order to ensure the stable movement of the bearing mechanism 2, the output-stable circulation system for gravity energy storage includes two connection systems symmetrically arranged with each other, and the two connection systems are respectively arranged at both ends of the bearing mechanism 2.

[0057] Preferably, as Figures 1 to 4 shown in Figures 1 to 4 , in the embodiment, the output-stable circulation system for gravity energy storage may further include a stabilization module. The stabilization module may include a stabilization track 801. The stabilization track 801 is arranged on the reference plane 9. In order to make the power generation process of the whole system more stable, the stabilization track 801 is additionally installed. The stabilization track 801 can be installed on the reference plane 9. The reference plane 9 can be, for example, one side of a mountain body, a building body, etc. facing the gravity energy storage system, and this reference plane 9 can be a vertical plane. In order to further ensure the stable movement of the bearing mechanism 2, a stabilization pulley 802 is also arranged at the end of the bearing mechanism 2, and the bearing mechanism 2 is slidably connected to the stabilization track 801 through the stabilization pulley 802.

[0058] The operation process of the output-stable circulation system for gravity energy storage is as follows: Refer to Figure 4, the heavy object block 1 is transported to a bearing mechanism 2 via a previous conveyor belt. After the heavy object block 1 is loaded on the bearing mechanism 2, it moves downward under the influence of gravity. At this time: First, the bearing mechanism 2 is slidably connected to the stable track 801 through the stable pulley 802 to ensure the stable sliding of the bearing mechanism 2; Second, the second connecting member 501 always maintains a uniform motion; Third, at this time, the bearing mechanism 2 is connected to the first connecting member 401 and the third connecting member 601 through the first transition member 301 and the second transition member 302 of the conversion mechanism (it can also be understood that 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 ends of the first transition member 301 and the second transition member 302 clamp the first connecting member 401 and the third connecting member 601); Fourth, the first connecting member 401 and the third connecting member 601 are driven by an external motor to gradually accelerate from zero speed to the same speed as the second connecting member 501. During this acceleration process, the pulley member 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 connecting member 501, and the bearing mechanism 2 is continuously transitioned from the first connecting member 401 and the third connecting member 601 to the second connecting member 501. After the transition, the heavy object block 1 can make the second connecting member 501 continue to maintain a uniform motion and convert gravitational potential energy into electrical energy. After the gravitational potential energy of the heavy object block 1 is gradually exhausted, the pulley member 304 of the conversion mechanism moves along the output track 703, the transition track 702, and the connecting track 701 and changes its position, and the relative position between the conversion mechanism and the bearing mechanism 2 changes again (resets). At this time, the speeds of the first connecting member 401 and the third connecting member 601 are the same as the speed of the second connecting member 501; the ends of the first transition member 301 and 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 speeds of the first connecting member 401 and the third connecting member 601 gradually decrease to zero, and the heavy object block 1 is unloaded. In addition, in order to improve efficiency and save energy, when unloading the heavy object block 1, when the speeds of the first connecting member 401 and the third connecting member 601 gradually decrease to zero, a heavy object block 1 can be loaded simultaneously above. During the operation of the entire system, the conversion of the bearing mechanism 2 carrying the heavy object block 1 is always continuous and stable.

[0059] After unloading the heavy object block 1, as Figure 3 shown in the lower part of, the output part 303 of the bearing mechanism 2 is disengaged from the second connecting member 501 and no longer connected to the second connecting assembly 5. The bearing mechanism 2 is driven by the first connecting assembly 4 and the third connecting assembly 6 to return to the top of the connection system and return to its original position, and at this time the output part 303 contacts the second connecting member 501 again.

[0060] The output-stable circulation system for gravity energy storage enables the system to achieve continuous and stable power generation through the cooperation of the connection system and the bearing mechanism; through the cooperation of the transition connection module, the output connection module, the conversion track module and the conversion mechanism, the loading and unloading of the heavy object blocks become continuous events, thereby avoiding sudden changes in the driving force on the bearing mechanism, making the output power more stable while increasing 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 pause during loading and unloading, improving the continuous operation ability and overall efficiency of the system, and ensuring the stability of the output power of the entire system.
