Description

[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.

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 gravity energy storage circulation system with stable output is provided, such as Figures 1 to 8 As shown, the gravity energy storage cycle system with stable output can generate electricity stably, and 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 the energy storage process of transporting the following heavy block 9 from a low place to a high place and the power generation process of transporting the following heavy block 9 from a high place to a low place. The gravity energy storage cycle 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 9 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 structures of the transition conversion module and the transport module of the output stable gravity energy storage circulation system are specifically described.

[0027] like Figure 1 As shown, in the embodiment, the transport module is arranged at both ends of the transition conversion module, and the transport module includes a carrying mechanism 5. The transport module is used to assist in transporting the following heavy block 9 to the carrying mechanism 5 installed on the transition conversion module, and at the same time make the following carrying mechanism 5 reflux to complete the circulation of the carrying mechanism 5.

[0028] Further, the transition conversion module may include a uniform output unit 1, a speed regulating unit 2 and a converter 3, the converter 3 can be connected to the uniform output unit 1 and / or the speed regulating unit 2, and the converter 3 is connected to the bearing mechanism 5. During the operation of the gravity energy storage cycle system with stable output, the uniform output unit 1 is always in a uniform motion state. Since the uniform output unit 1 is always in a uniform motion, the electric energy output by the uniform output unit 1 can always be stably output during the power generation process of the gravity energy storage cycle system with stable output. The driving force of the uniform motion of the uniform output unit 1 can be driven by the first weight block 9 through the gravitational potential energy or driven by an external motor so that the uniform output unit 1 is in a uniform state at the beginning. The speed regulating unit 2 is driven by an external motor (not shown) so that the speed of the speed regulating unit 2 can increase from zero to the same speed as the uniform output unit 1, and then decelerate to zero. The converter 3 can make the bearing mechanism 5 (the bearing mechanism 5 carries the weight block 9) transition from the speed regulating unit 2 to the uniform output unit 1, and then transition from the uniform output unit 1 to the speed regulating unit 2.

[0029] By making use of the "uniform output unit 1 always in uniform motion", the loading or unloading of the weight block 9 can be made into a continuous event. If the loading and unloading of the weight block 9 are continuous, the driving force of the change will be smaller. Principle explanation: After simulation tests, if the loading and unloading of the weight block 9 are completed in an instant for the uniform output unit 1, then as long as the loading and unloading are slightly out of sync, the bearing capacity will suddenly change by 100%. If the loading and unloading are continuous, even if the loading and unloading are slightly out of sync, the bearing capacity will not have a large sudden change, thereby making the output power more stable.

[0030] Based on this, the core design principle of the gravity energy storage circulation system with stable output is to use the speed regulating part 2 to bear the instantaneous load-bearing force of the heavy object 9 entering the carrying mechanism 5, and then use the converter 3 to transfer the carrying mechanism 5 to the uniform speed output part 1. Specifically, during loading, when the speed of the speed regulating part 2 is zero, the heavy object 9 enters the carrying mechanism 5 through the transport module, and the speed regulating part 2 gradually accelerates until it reaches the same speed as the uniform speed output part 1. The converter 3 can continuously transfer the carrying mechanism 5 to the uniform speed output part 1; during unloading, the speed regulating part 2 is at the same speed as the uniform speed output part 1 (it can be understood that: when the speed of the speed regulating part 2 is the same as that of the uniform speed output part 1, the speed regulating part 2 is at the same speed as the uniform speed output part 1). Figure 1 The loading in the middle and upper part transfers the weight block 9 to the uniform speed output part 1, which is located at Figure 1The unloading at the lower middle part transfers the heavy block 9 to the speed regulating part 2, that is, loading and unloading can be carried out simultaneously). The carrying mechanism 5 loaded with the heavy block 9 is continuously transferred back to the speed regulating part 2 from the uniform output part 1 through the converter 3 at a uniform speed. During the transfer, the speed of the speed regulating part 2 gradually slows down to zero, and the heavy block 9 is finally transported out by the bottom transport module. In order to realize the power generation of gravity energy storage, the uniform output part 1 can be connected to a generator, and the uniform output part 1 drives the power generation parts such as rotating wheels, so that the generator generates electricity. The power generation part can adopt the means in the prior art, which are known to those skilled in the art, so they will not be described here.

[0031] Further, the converter 3 may include a first connection part 301, a second connection part 302 and a position adjustment part 303, wherein the first connection part 301 and the second connection part 302 are connected via the position adjustment part 303, the uniform speed output part 1 is arranged at the first connection part 301, the speed regulating part 2 is arranged at the second connection part 302, and the position adjustment part 303 is connected to the position adjustment track, and the position adjustment part 303 is driven by the position adjustment track to change its position to be close to the first connection part 301 or the second connection part 302. When the position adjustment part 303 is close to the first connection part 301, the converter 3 is arranged at the uniform speed output part 1; when the position adjustment part 303 is close to the second connection part 302, the converter 3 is arranged at the speed regulating part 2. The position adjustment part 303 changes its position via the position adjustment track. The above “converter 3 can continuously transfer the support mechanism 5 to the uniform speed output part 1” and “converter 3 continuously transfers from the uniform speed output part 1 back to the speed regulating 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 uniform speed output part 1 or the speed regulating part 2 at different positions, thereby realizing transfer and rotation. Since the position change of the position adjustment part 303 is realized by the position adjustment track, the transfer and rotation are continuous.

[0032] The output-stable gravity energy storage cycle 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 unit 1, the speed regulating unit 2 and the converter 3, the loading and unloading of the heavy object block 9 is formed into a continuous event, thereby avoiding the sudden change of the driving force on the bearing mechanism 5, making the output power more stable while improving the fatigue life of the mechanical system; because the uniform output unit 1 is always in a uniform output state, the operation of the entire system is continuous and stable, and the system does not need to be suspended during loading and unloading, which improves the continuous operation capability and overall efficiency of the system; through the cooperation of the uniform output unit 1 and the speed regulating unit 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.

[0033] Preferably, if Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, in the embodiment, the uniform speed output part 1 may include a first connecting member 101, a first rotating wheel 102 and a second rotating wheel 103, and the first rotating wheel 102 and the second rotating wheel 103 are respectively arranged at the two ends of the transition conversion module, that is, the first rotating wheel 102 and the second rotating wheel 103 need to be installed at the top and the bottom of the entire system to ensure the operation of the system. The first connecting member 101 surrounds the first rotating wheel 102 and the second rotating wheel 103, and the first connecting member 101 is arranged on the first connecting part 301 around one side of the first rotating wheel 102. The first connecting member 101 can be, for example, a first steel cable, and the first steel cable surrounds the first rotating wheel 102 and the second rotating wheel 103 to form a steel cable circulation system. Since the first connecting member 101 plays the function of output and connection, the connection of the entire system, such as Figure 2 As shown, the first connecting member 101 on the left side of the first rotating wheel 102 is connected to the converter 3, while the right side is unloaded. It should be noted that since the first connecting member 101 is cyclically rotated around the first rotating wheel 102 and the second rotating wheel 103, the left side and the right side only represent Figure 2 The current status shown.

[0034] Preferably, if Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, in the embodiment, the speed regulating part 2 may include a second connecting member 201, a third rotating wheel 202 and a fourth rotating wheel 203, and the third rotating wheel 202 and the fourth rotating wheel 203 are respectively arranged at the two ends of the transition conversion module, and similarly, the two ends here are also the top and the bottom of the entire system. The second connecting member 201 surrounds the third rotating wheel 202 and the fourth rotating wheel 203, and the second connecting member 201 is respectively arranged on the second connecting parts 302 of the two converters 3 on both sides around the third rotating wheel 202. Similarly, the second connecting member 201 can be, for example, a second steel cable, and the second steel cable surrounds the third rotating wheel 202 and the fourth rotating wheel 203 to form a steel cable circulation system. In order to ensure that the loading located above the entire system and the unloading located below the entire system can be carried out synchronously, therefore, in Figure 2 In the figure, the left and right sides of the second connecting member 201 are connected with converters 3. In addition, it should be further explained that the two converters 3 in the "second connecting parts 302 respectively provided on the two converters 3 on both sides" here only represent that the two sides of the second connecting member 201 are connected with converters 3. Since the gravity energy storage system can realize the transportation of multiple weight blocks 9 at the same time, and a carrying mechanism 5 carrying a weight block 9 requires a converter 3 to be connected to the second steel cable, the second steel cable can actually connect multiple converters 3 at the same time.

[0035] The output stable gravity energy storage circulation system can be formed as a "double steel cable system", wherein the first steel cable is driven by the first rotating wheel 102 to always be in a uniform motion state (the first rotating wheel 102 can be connected to an external motor, and the first rotating wheel 102 can be driven by the external motor to rotate), and the second steel cable is driven by the third rotating wheel 202 to accelerate from zero to the same synchronous speed as the first steel cable, and then gradually decelerate to zero. In order to ensure the normal operation of the system and avoid interference, the diameters of the third rotating wheel 202 and the fourth rotating wheel 203 are larger than the diameters of the first rotating wheel 102 and the second rotating wheel 103.

[0036] Preferably, if Figures 1 to 5 As shown, in the embodiment, the position adjustment track is arranged between the uniform speed output part 1 and the speed regulating part 2. Specifically, the position adjustment track may include a connecting track part 401, a transition track part 402 and an output track part 403, wherein 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 speed output part 1, and the connecting track part 401 is close to the speed regulating part 2. Figure 4 and Figure 5 In the embodiment, the connecting track portion 401 and the output track portion 403 are both formed as vertical tracks, while the transition track portion 402 is formed as an inclined track. The connecting track portion 401 and the output track portion 403 are not on the same horizontal plane, and the two are transitionally connected through the transition track portion 402. Based on this, it can be understood that the "close" here can be understood as the output track portion 403 is arranged closer to the uniform speed output portion 1, while the connecting track portion 401 is arranged closer to the speed regulating portion 2.

[0037] 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 the position, so that the position adjustment part 303 and the first connecting part 301 clamp the uniform speed output part 1 or the position adjustment part 303 and the second connecting part 302 clamp the speed regulating part 2.

[0038] See also Figure 7 The end of the position adjustment part 303 of the converter 3 is provided with a pulley, through which the position adjustment part 303 can slide on the position adjustment track. Figure 7 In the embodiment, a through hole for the first steel cable to pass through is provided between the first connecting part 301 and the position adjusting part 303, and a through hole for the second steel cable to pass through is provided between the second connecting part 302 and the position adjusting part 303. Since the pulley slides on the position adjusting track at different positions, the position adjusting part 303 can clamp the first steel cable or the second steel cable together with the first connecting part 301 or the second connecting part 302 at different positions to achieve transition.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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 .

[0044] Preferably, if Figure 6As shown, in the embodiment, the converter 3 is detachably connected to the supporting mechanism 5. A buckle portion 501 is provided at the end of the supporting mechanism 5, and a block portion 304 is provided at the end of the converter 3. The block portion 304 is formed as a handle structure with a hollow interior, and the buckle portion 501 is formed as a protruding buckle, which can be engaged with the block portion 304.

[0045] See also Figure 5 , the converter 3 is reset through the second connecting member 201, and the converter 3 is always located on the transition conversion module. For example, when the second steel cable rotates around the third rotating wheel 202, the converter 3 can move 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 carrying mechanism 5. The carrying mechanism 5 is reset through the transport module, and the carrying mechanism 5 is reflowed separately through the transport module. When reflowing, the carrying mechanism 5 is first separated from the converter 3, and then re-docked with the converter 3. The separation and docking methods can be realized by the transport module. For example, a lifting cylinder or a lifting scissor device is provided at both ends of the transport module. When separating, the lifting device rises, so that the carrying mechanism 5 is separated from the converter 3 first, and then descends, and the carrying mechanism 5 can be reflowed through the conveyor belt; when docking, the lifting device is also raised, and the carrying mechanism 5 is aligned with the converter 3, and then descends, so that the carrying mechanism 5 is re-docked with the converter 3. In addition, it should be noted that the transport module can be a device in the prior art that can realize the reflux of the carrying mechanism 5. As for the transport device for reflux and the lifting device or other devices for docking and separation, they can all be devices in the prior art, and technical personnel in this field can make reasonable choices.

[0046] Preferably, if Figure 1 and Figure 2 As shown, in the embodiment, the transport module may further include a stabilizing track 7, which is arranged on a reference plane 8, and a sliding wheel 502 is arranged at the end of the supporting mechanism 5, and the sliding wheel 502 is slidably connected with the stabilizing track 7. In order to make the power generation process of the entire system more stable, an additional stabilizing track 7 is installed, and the stabilizing track 7 can be installed on the reference plane 8, and the reference plane 8 can be, for example, a side of a mountain, a building, etc. facing the gravity energy storage system, and this reference plane 8 can be a vertical plane.

[0047] The operation process of the output stable gravity energy storage cycle system is as follows: Figure 5During loading, the heavy object 9 is transferred to a supporting mechanism 5 via the preceding conveyor belt, and at this time, the supporting mechanism 5 is connected to the second connecting member 201 via the converter 3 . The weight block 9 is affected by gravity and moves downward. At this time: 1. The supporting mechanism 5 is slidably connected to the stable track 7 through the sliding wheel 502 to ensure the sliding stability of the supporting mechanism 5; 2. The first connecting member 101 always maintains uniform motion; 3. 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 at this time jointly clamp the second connecting member 201; 4. The second connecting member 201 is driven by the third rotating wheel 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 clamps the first connecting member 101 together with the first connecting part 301, completing the continuous transition of the supporting mechanism 5 from the second connecting member 201 to the first connecting member 101. After the transition, the weight block 9 can make the first connecting member 101 continue to move at a constant speed and convert the gravitational potential energy into electrical energy. Figure 1 and Figure 4 , when the bearing mechanism 5 carrying the heavy object block 9 moves to the position of the output track part 403 located at the bottom, the heavy object block 9 is ready to be unloaded, 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 clamps the second connecting member 201 together with the second connecting part 302, so that the bearing mechanism 5 gradually transitions from the uniform speed output part 1 to the speed regulating part 2 (at this time, the speed of the speed regulating part 2 is the same as the speed of the uniform speed output part 1). After that, it is driven by an external motor, so that the speed of the speed regulating 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, when the speed of the speed regulating part 2 is gradually reduced to zero, the heavy object block 9 can be loaded on the top at the same time. 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 reflux of the carrying mechanism 5 after loading and unloading can be achieved through the carrier reflux unit 6, which has been mentioned in the above description and will not be repeated here.

[0048] The output-stable gravity energy storage cycle system can realize continuous and stable power generation through the cooperation of the transition conversion module and the transport module. The loading and unloading of the heavy blocks are formed into continuous events through the cooperation of the uniform output unit, the speed regulating unit and the converter, 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 unit 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 during loading and unloading, which improves the continuous operation capability and overall efficiency of the system; through the cooperation of the uniform output unit and the speed regulating unit, the loading and unloading of the heavy blocks can be completed synchronously, further reducing the fluctuation of the driving force and ensuring the stability of the output power of the whole system.
