Description

Technical Field

[0001] This application relates to the technical field of gravity energy storage, and in particular to a gravity energy storage cycle system with stable output. Background Art

[0002] Gravity energy storage is a method of storing energy using gravitational potential energy. Its basic principle is to lift gravity power generation blocks to a high place to store energy. When energy needs to be released, these gravity power generation blocks are allowed to drop, thereby driving a generator to generate electricity.

[0003] Existing gravity energy storage devices have the following problems: First, the driving force changes suddenly. In the prior art, the loading and unloading of heavy object blocks are discrete events, that is, they are suddenly mounted or disengaged from the bearing mechanism at a certain moment, resulting in a sudden change in the driving force on the bearing mechanism, and further reducing 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, resulting in unstable output power.

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

[0005] In view of this, to overcome the defects of the prior art, the present invention provides a gravity energy storage cycle system with stable output, effectively solving the problems of sudden change in driving force, discontinuous operation, and unstable output power existing in existing gravity energy storage devices.

[0006] According to a gravity energy storage cycle system with stable output provided by the present invention, it is used for the transportation of heavy object blocks. Among them, the gravity energy storage cycle system with stable output includes a transition conversion module and a transportation module. The transportation module is arranged at both ends of the transition conversion module. The transition conversion module includes a constant-speed output part, a speed regulation part, and a converter. The converter can be connected to the constant-speed output part and / or the speed regulation part. The transportation module includes a bearing mechanism, and the converter is connected to the bearing mechanism; The converter includes a first connection part, a second connection part, and a position adjustment part. The first connection part and the second connection part are connected through the position adjustment part. The constant-speed output part is arranged on the first connection part, the speed regulation part is arranged on the second connection part, and the position adjustment part is connected to a position adjustment track. The position adjustment part changes its position to approach the first connection part or the second connection part through the drive of the position adjustment track.

[0007] Preferably, the uniform output part includes a first connecting piece, a first runner and a second runner. The first runner and the second runner are respectively arranged at two ends of the transition conversion module. The first connecting piece surrounds the first runner and the second runner, and one side of the first connecting piece surrounding the first runner is arranged at the first connecting part.

[0008] Preferably, the speed regulation part includes a second connecting piece, a third runner and a fourth runner. The third runner and the fourth runner are respectively arranged at two ends of the transition conversion module. The second connecting piece surrounds the third runner and the fourth runner, and both sides of the second connecting piece surrounding the third runner are respectively arranged at the second connecting parts of the two converters.

[0009] Preferably, the position adjustment track includes a connecting track part, a transition track part and an output track part. The output track part is connected to the connecting track part through the transition track part. The output track part is close to the uniform output part, and the connecting track part is close to the speed regulation part. The position adjustment part can slide on the connecting track part, the transition track part and the output track part to change its position, so that the position adjustment part clamps the uniform output part with the first connecting part or the position adjustment part clamps the speed regulation part with the second connecting part.

[0010] Preferably, the connecting track part includes a first bending part and a second bending part. The first bending part and the second bending part are respectively close to two ends of the transition conversion module. Two ends of the connecting track part are arranged facing each other through the first bending part and the second bending part. Two ends of the connecting track part are respectively connected to an output track part through a transition track part.

[0011] Preferably, the transportation module further includes a carrier return part. The first end of the carrier return part faces the transportation direction of the heavy object block, and the second end of the carrier return part is close to the transportation direction of the heavy object block, so that the carrying mechanism can return from one end of the transition conversion module to the other end.

[0012] Preferably, the converter is detachably connected to the carrying mechanism. The converter is reset through the second connecting piece, and the carrying mechanism is reset through the transportation module.

[0013] Preferably, the transportation module further includes a stable track. The stable track is arranged on the reference plane, and a sliding wheel is arranged at the end of the carrying mechanism. The sliding wheel is slidably connected to the stable track.

[0014] Preferably, the position adjustment part is made of soft material.

[0015] Preferably, contact surfaces of the first connecting portion and the second connecting portion with the uniform speed output portion and the speed regulating portion are provided with serrated patterns.

[0016] According to the gravity energy storage circulation system with stable output of the present invention, the system can realize continuous and stable power generation through the cooperation of the transition conversion module and the transport module. Through the cooperation of the uniform output part, the speed regulating part and the converter, the loading and unloading of the heavy block is formed into a continuous event, thereby avoiding the sudden change of the driving force on the bearing mechanism, making the output power more stable while improving the fatigue life of the mechanical system; because the uniform output part is always in a uniform output state, the operation of the whole system is continuous and stable, and the system does not need to be suspended in the case of loading and unloading, which improves the continuous operation ability and overall efficiency of the system; through the cooperation of the uniform output part and the speed regulating part, the loading and unloading of the heavy block can be completed synchronously, further reducing the fluctuation of the driving force and ensuring the stability of the output power of the whole system.

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 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts fall within 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 products of this application are usually placed during 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 therefore should not be construed as a limitation of the present application. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0030] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required 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 situations.

[0032] According to a gravity energy storage cycle system with stable output provided by the present invention, as Figures 1 to 8 shown, the gravity energy storage cycle system with stable output can generate electricity stably. The gravity energy storage cycle system with stable output includes a transition conversion module and a transportation module. It should be noted here that gravity energy storage actually includes an energy storage process of transporting the following heavy object 9 from a low place to a high place and a power generation process of transporting the following heavy object 9 from a high place to a low place. The gravity energy storage cycle system with stable output can achieve stable power generation during the power generation process. As for the energy storage process, a device in the prior art can be used to transport the heavy object 9 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 transition conversion module and the transportation module of the gravity energy storage cycle system with stable output.

[0034] As Figure 1 shown, in the embodiment, the transportation module is arranged at both ends of the transition conversion module. The transportation module includes a carrying mechanism 5. The transportation module is used to assist in transporting the following heavy object 9 to the carrying mechanism 5 installed on the transition conversion module, and at the same time, the following carrying mechanism 5 returns, completing the cycle of the carrying mechanism 5.

[0035] Furthermore, the transition conversion module may include a constant-speed output unit 1, a speed regulation unit 2, and a converter 3. The converter 3 can be connected to the constant-speed output unit 1 and / or the speed regulation unit 2, and the converter 3 is connected to the carrying mechanism 5. During the operation of the gravity energy storage cycle system with stable output, the constant-speed output unit 1 is always in a state of uniform motion. Since the constant-speed output unit 1 is always in uniform motion, during the power generation process of the gravity energy storage cycle system with stable output, the electric energy output through the constant-speed output unit 1 can always be stably output. The driving force for the uniform motion of the constant-speed output unit 1 can be realized by driving the first heavy object block 9 through gravitational potential energy or by an external motor to make the constant-speed output unit 1 initially in a uniform state. The speed regulation unit 2 is driven by an external motor (not shown), so that the speed of the speed regulation unit 2 can be increased from zero to the same as the speed of the constant-speed output unit 1 and then decelerated to zero. The converter 3 can make the carrying mechanism 5 (the carrying mechanism 5 carries the heavy object block 9) transition from the speed regulation unit 2 to the constant-speed output unit 1, and then from the constant-speed output unit 1 to the speed regulation unit 2.

[0036] By using the fact that "the constant-speed output unit 1 is always in uniform motion", the loading or unloading of the heavy object block 9 can be made into a continuous event. If the loading and unloading of the heavy object block 9 are continuous, the changing driving force will be smaller. Principle explanation: After simulation tests, if the loading and unloading of the heavy object block 9 are completed instantaneously for the constant-speed output unit 1, then as long as there is a little out-of-sync between loading and unloading, the bearing capacity will mutate by 100%. However, if the loading and unloading are continuous, even if there is a slight out-of-sync between loading and unloading, the bearing capacity will not have a large mutation, thus making the output power more stable.

[0037] Based on this, the core design principle of the gravity energy storage cycle system with stable output lies in: using the speed regulation unit 2 to bear the bearing capacity at the moment when the heavy object block 9 enters the carrying mechanism 5, and then using the converter 3 to transition the carrying mechanism 5 to the constant-speed output unit 1. Specifically, during loading, when the speed of the speed regulation unit 2 is zero, the heavy object block 9 enters the carrying mechanism 5 through the transportation module, and the speed regulation unit 2 gradually accelerates until it is the same as the speed of the constant-speed output unit 1. The converter 3 can continuously transfer the carrying mechanism 5 to the constant-speed output unit 1; during unloading, the speed of the speed regulation unit 2 is the same as that of the constant-speed output unit 1 at this time (it can be understood that: in the case where the speed of the speed regulation unit 2 is the same as that of the constant-speed output unit 1, the loading above Figure 1 transitions the heavy object block 9 to the constant-speed output unit 1, and the loading above Figure 1The unloading at the lower middle transfers the heavy object block 9 to the speed regulation part 2 (i.e., the loading and unloading can be carried out synchronously). The bearing mechanism 5 loaded with the heavy object block 9 continuously returns from the constant-speed output part 1 to the speed regulation part 2 through the converter 3 at a constant speed. During the return process, the speed of the speed regulation part 2 gradually decelerates to zero, and finally the heavy object block 9 is transported out by the bottom transport module. In order to realize the power generation of gravity energy storage, the constant-speed output part 1 can be connected to a generator, and the constant-speed output part 1 drives power generation parts such as a rotating wheel, thereby enabling the generator to generate 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 elaborated here.

[0038] Furthermore, the converter 3 can include a first connection part 301, a second connection part 302, and a position adjustment part 303. The first connection part 301 and the second connection part 302 are connected through the position adjustment part 303. The constant-speed output part 1 is arranged on the first connection part 301, the speed regulation part 2 is arranged on the second connection part 302, and the position adjustment part 303 is connected to a position adjustment track. The position adjustment part 303 changes its position to approach the first connection part 301 or the second connection part 302 by the drive of the position adjustment track. When the position adjustment part 303 approaches the first connection part 301, the converter 3 is arranged on the constant-speed output part 1; when the position adjustment part 303 approaches the second connection part 302, the converter 3 is arranged on the speed regulation part 2. The position adjustment part 303 changes its position through the position adjustment track. The above "the converter 3 can continuously transfer the bearing mechanism 5 to the constant-speed output part 1" and "the converter 3 continuously returns from the constant-speed output part 1 to the speed regulation part 2" can be understood as: the position adjustment part 303 of the converter 3 can change its position through the track of the position adjustment track, so that the converter 3 is connected to the constant-speed output part 1 or the speed regulation part 2 at different positions, thereby realizing the transfer and rotation. Since the position change of the position adjustment part 303 is realized through the position adjustment track, the transfer and rotation are continuous.

[0039] This gravity energy storage cycle system with stable output enables the system to achieve continuous and stable power generation through the cooperation of the transition conversion module and the transport module. Through the cooperation of the constant-speed output part 1, the speed regulation part 2, and the converter 3, the loading and unloading of the heavy object block 9 become continuous events, thereby avoiding sudden changes in the driving force on the bearing mechanism 5, making the output power more stable while improving the fatigue life of the mechanical system; since the constant-speed output part 1 is always in a constant-speed output state, the entire system runs continuously and stably, without the need for the system to pause during loading and unloading, improving the continuous operation ability and overall efficiency of the system; through the cooperation of the constant-speed output part 1 and the speed regulation part 2, the loading and unloading of the heavy object block 9 can be completed synchronously, further reducing the fluctuation of the driving force and ensuring the stability of the output power of the entire system.

[0040] Preferably, asFigure 1 , Figure 2 , Figure 5 and Figure 8 As shown in Figure 1 , Figure 2 , Figure 5 and Figure 8 , in the embodiment, the constant-speed output unit 1 may include a first connecting member 101, a first runner 102 and a second runner 103. The first runner 102 and the second runner 103 are respectively arranged at both ends of the transition conversion module, that is, the first runner 102 and the second runner 103 need to be installed at the top and bottom of the whole system to ensure the operation of the system. The first connecting member 101 surrounds the first runner 102 and the second runner 103, and one side of the first connecting member 101 surrounding the first runner 102 is arranged at the first connecting portion 301. The first connecting member 101 may be, for example, a first steel cable, and the first steel cable surrounds the first runner 102 and the second runner 103 to form a steel cable circulation system. Since the first connecting member 101 functions as output and connection, in the connection of the whole system, such as Figure 2 As shown in Figure 2 , the first connecting member 101 on the left side of the first runner 102 is connected to the converter 3, while the right side is unloaded. It should be noted here that since the first connecting member 101 rotates around the first runner 102 and the second runner 103, the left and right sides only represent the state at this moment as shown in Figure 2 Figure 2 .

[0041] Preferably, as shown in ,

[0041] , Figure 1 , Figure 2 , Figure 5 and Figure 8 , in the embodiment, the speed regulation unit 2 may include a second connecting member 201, a third runner 202 and a fourth runner 203. The third runner 202 and the fourth runner 203 are respectively arranged at both ends of the transition conversion module. Similarly, both ends here are also the top and bottom of the whole system. The second connecting member 201 surrounds the third runner 202 and the fourth runner 203, and both sides of the second connecting member 201 surrounding the third runner 202 are respectively arranged at the second connecting portions 302 of two converters 3. Similarly, the second connecting member 201 may be, for example, a second steel cable, and the second steel cable surrounds the third runner 202 and the fourth runner 203 to form a steel cable circulation system. In order to ensure that the loading above the whole system and the unloading below the whole system can be carried out synchronously, therefore, in Figure 2 , converters 3 are connected to both the left and right sides of the second connecting member 201. In addition, it should be further noted here that the two converters 3 in "respectively arranged at the second connecting portions 302 of two converters 3 on both sides" only mean that converters 3 are connected to both sides of the second connecting member 201. Since the gravity energy storage system can simultaneously transport multiple heavy blocks 9, and a loading mechanism 5 carrying a heavy block 9 requires a converter 3 to be connected to the second steel cable, in fact, the second steel cable can be connected to multiple converters 3 at the same time.

[0042] ​​​​​​​​The gravity energy storage cycle system with stable output can be formed into a "double steel cable system", in which the first steel cable is driven by the first runner 102 and is always in a uniform motion state (the first runner 102 can be connected to an external motor, and the first runner 102 is driven to rotate by the external motor). The second steel cable can be driven by the third runner 202 to accelerate from zero to the synchronous speed equal to the motion speed of the first steel cable, and then gradually decelerate to zero. To ensure the normal operation of the system and avoid interference, the diameters of the third runner 202 and the fourth runner 203 are larger than the diameters of the first runner 102 and the second runner 103.

[0043] Preferably, as Figures 1 to 5 shown, in the embodiment, the position adjustment track is arranged between the uniform output part 1 and the speed regulation part 2. Specifically, the position adjustment track can include a connecting track part 401, a transition track part 402 and an output track part 403. The output track part 403 is connected to the connecting track part 401 through the transition track part 402. The output track part 403 is close to the uniform output part 1, and the connecting track part 401 is close to the speed regulation part 2. In Figure 4 and Figure 5 both the connecting track part 401 and the output track part 403 are formed as vertical tracks, while the transition track part 402 is formed as an inclined track. The connecting track part 401 and the output track part 403 are not on the same horizontal plane, and these two are connected through the transition track part 402. Based on this, it can be understood that the proximity here means that the setting position of the output track part 403 is closer to the uniform output part 1, and the setting position of the connecting track part 401 is closer to the speed regulation part 2.

[0044] Furthermore, the position adjustment part 303 can slide on the connecting track part 401, the transition track part 402 and the output track part 403 to change its position, so that the position adjustment part 303 clamps the uniform output part 1 with the first connecting part 301 or the position adjustment part 303 clamps the speed regulation part 2 with the second connecting part 302.

[0045] See Figure 7 where a pulley is arranged at the end of the position adjustment part 303 of the converter 3, and through the pulley, the position adjustment part 303 can slide on the position adjustment track. At the same time, in Figure 7 a through hole for the first steel cable to pass through is arranged between the first connecting part 301 and the position adjustment part 303, and a through hole for the second steel cable to pass through is arranged between the second connecting part 302 and the position adjustment part 303. Since the pulley slides on the position adjustment track at different positions, the position adjustment part 303 can clamp the first steel cable or the second steel cable with the first connecting part 301 or the second connecting part 302 at different positions to achieve transition.

[0046] Preferably, in the embodiment, in order to enable the position adjusting portion 303 to change position following the position adjusting track, the position adjusting portion 303 may be composed of a soft material, and the soft material may be, for example, soft polyurethane.

[0047] Preferably, in the embodiment, the position adjustment portion 303 may also be formed as a rolling contact driven by a pulley to achieve position change; or, a sliding contact driven by a slider to achieve position change.

[0048] Furthermore, in order to increase the friction force of clamping, the contact surfaces of the first connecting portion 301 and the second connecting portion 302 with the uniform speed output portion 1 and the speed regulating portion 2 are provided with serrated patterns.

[0049] Preferably, if Figure 3 and Figure 4 As shown, in the embodiment, the connecting track portion 401 includes a first bending portion 404 and a second bending portion 405, and the first bending portion 404 and the second bending portion 405 are respectively close to the two ends of the transition conversion module to cooperate with the uniform speed output portion 1 and the speed regulating portion 2. The two ends of the connecting track portion 401 are arranged facing each other through the first bending portion 404 and the second bending portion 405; the two ends of the connecting track portion 401 are respectively connected to an output track portion 403 through a transition track portion 402. A transition track portion 402 and an output track portion 403 located at the upper part are used for transition during loading, and a transition track portion 402 and an output track portion 403 located at the lower part are used for transition during unloading.

[0050] Preferably, if Figure 1 and Figure 2 As shown, in an embodiment, the transport module may further include a carrier reflux portion 6, wherein the first end of the carrier reflux portion 6 faces the transport direction of the heavy object block 9, and the second end of the carrier reflux portion 6 is close to the transport direction of the heavy object block 9, so that the carrying mechanism 5 can reflux from one end of the transition conversion module to the other end. In order to allow the unloaded carrying mechanism 5 to reflux, a carrier reflux portion 6 is provided at the upper and lower ends of the transition conversion module. After the heavy object block 9 is transported to the lower end of the transition conversion module by the carrying mechanism 5 and unloaded, the unloaded carrying mechanism 5 is rotated to the right side of the speed regulating portion 2 through the carrier reflux portion 6 at the lower end, and then driven to rise through the right side of the speed regulating portion 2, and then rotated to the left side of the speed regulating portion 2 through the carrier reflux portion 6 at the upper end. The left side and the right side here can be understood as Figure 1 The left and right sides of the .

[0051] Preferably, if Figure 6As shown, in the embodiment, the converter 3 is detachably connected to the carrier mechanism 5. A snap portion 501 is provided at an end of the carrier mechanism 5, and a block portion 304 is provided at an end of the converter 3. The block portion 304 is formed into an approximately handle structure with a hollow interior, and the snap portion 501 is formed into a protruding snap. The snap portion 501 can be snap-connected to the block portion 304.

[0052] Refer to Figure 5 , the converter 3 is reset by the second connecting member 201. The converter 3 is always located on the transition conversion module. For example, when the second steel cable rotates around the third runner 202, the converter 3 can move together with the second steel cable and move from the right side of the second steel cable to the left side, and then re-dock with the returning carrier mechanism 5. The carrier mechanism 5 is reset by the transportation module. The carrier mechanism 5 returns separately through the transportation module. During the return, the carrier mechanism 5 first separates from the converter 3 and then re-docks with the converter 3. The separation and docking methods can both be realized by the transportation module. For example, lifting cylinders or scissor devices for lifting are provided at both ends of the transportation module. During separation, the lifting device rises, so that the carrier mechanism 5 first separates from the converter 3 and then descends. The carrier mechanism 5 can return through the conveyor belt. During docking, the lifting device also rises, aligns the carrier mechanism 5 with the converter 3, and then descends, so that the carrier mechanism 5 re-docks with the converter 3. In addition, it should be noted that the transportation module can be a device in the prior art that can realize the return of the carrier mechanism 5. As for the transportation device for return and the lifting device or other devices for docking and separation, they can all be devices in the prior art, and those skilled in the art can make a reasonable choice.

[0053] Preferably, as Figure 1 and Figure 2 shown, in the embodiment, the transportation module may further include a stable track 7. The stable track 7 is arranged on the reference plane 8. A sliding wheel 502 is provided at an end of the carrier mechanism 5. The sliding wheel 502 is slidably connected to the stable track 7. In order to make the power generation process of the entire system more stable, the stable track 7 is additionally installed. The stable track 7 can be installed on the reference plane 8. The reference plane 8 can be, for example, one side of a mountain body, a building body, etc. facing the gravity energy storage system. This reference plane 8 can be a vertical plane.

[0054] The operation process of the gravity energy storage cycle system with stable output is as follows: Refer to Figure 5, during loading, the heavy object block 9 is transported to a bearing mechanism 5 via a previous conveyor belt. At this time, the bearing mechanism 5 is connected to the second connecting member 201 through a converter 3. Affected by gravity, the heavy object block 9 moves downward. At this time: First, the bearing mechanism 5 is slidably connected to the stable track 7 through a sliding wheel 502 to ensure the stable sliding of the bearing mechanism 5; Second, the first connecting member 101 always maintains a uniform motion; Third, the position adjustment part 303 is restricted by the connecting track part 401, so that the position adjustment part 303 and the second connecting part 302 jointly clamp the second connecting member 201 at this time; Fourth, the second connecting member 201 is driven by the third runner 202 and gradually accelerates from a speed of zero to the same speed as the first connecting member 101. During this acceleration process, the position adjustment part 303 slides along the connecting track part 401, the transition track part 402, and the output track part 403 in sequence. When sliding to the output track part 403, the position adjustment part 303 gradually approaches the first connecting part 301 and jointly clamps the first connecting member 101 with the first connecting part 301, completing the continuous transition of the bearing mechanism 5 from the second connecting member 201 to the first connecting member 101. After the transition, the heavy object block 9 can make the first connecting member 101 continue to maintain a uniform motion and convert gravitational potential energy into electrical energy. See Figure 1 and Figure 4 , when the bearing mechanism 5 carrying the heavy object block 9 moves to the position where the lower output track part 403 is located, it is ready to unload the heavy object block 9. The position adjustment part 303 of the converter 3 is docked with the output track part 403, and the position adjustment part 303 slides along the output track part 403, the transition track part 402, and the connecting track part 401 in sequence. When sliding to the connecting track part 401, the position adjustment part 303 gradually approaches the second connecting part 302 and jointly clamps the second connecting member 201 with the second connecting part 302, so that the bearing mechanism 5 gradually transitions from the uniform output part 1 to the speed regulation part 2 (at this time, the speed of the speed regulation part 2 is the same as that of the uniform output part 1). Then, driven by an external motor, the speed of the speed regulation part 2 is gradually reduced to zero, and finally the heavy object block 9 is unloaded. In addition, in order to improve efficiency and save energy, when unloading the heavy object block 9 and the speed of the speed regulation part 2 is gradually reduced to zero, the heavy object block 9 can be loaded simultaneously above. During the operation of the entire system, the conversion of the bearing mechanism 5 carrying the heavy object block 9 is always continuous and stable. In addition, the return flow of the bearing mechanism 5 after loading and unloading can be realized through the vehicle return part 6, which has been mentioned above and will not be elaborated here.

[0055] The gravity energy storage cycle system with stable output enables the system to achieve continuous and stable power generation through the cooperation of the transition conversion module and the transportation module. Through the cooperation of the uniform output unit, the speed regulation unit and the converter, 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 improving the fatigue life of the mechanical system; since the uniform output unit is always in a state of uniform output, the entire system operates continuously and stably, without the need for the system to pause during loading and unloading, improving the continuous operation ability and overall efficiency of the system; through the cooperation of the uniform output unit and the speed regulation unit, the loading and unloading of the heavy object blocks can be completed synchronously, further reducing the fluctuation of the driving force and ensuring the stability of the output power of the entire system.
