Description

Technical Field

[0001] The present application relates to the field of gravity energy storage technology, and in particular to a gravity energy storage power generation and storage cycle device with a high duty cycle. Background Art

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

[0003] In the existing scheme, the weight block bearing mechanism is separately dispatched from the weight block, and each occupies its own channel space. The overall space occupied is large, the integration is low, and the equipment utilization rate is low, resulting in a large area of ​​the overall gravity energy storage equipment and high land costs. In some scenarios with limited space, such as gravity energy storage projects developed using abandoned mines, it is impossible to deploy gravity energy storage circulation equipment, which limits the application of gravity energy storage.

[0004] In addition, in general scenarios and scenarios with limited space, there are still the following problems: First, the existing gravity energy storage power generation scheme cannot achieve single-channel circulation. The front-end mechanical input device connected to the generator will start and stop from time to time due to the transportation of the heavy block. Each start and stop will have a large impact on the output power, which makes the gravity energy storage charging power and discharge power present a "step-by-step, non-smooth" adjustment characteristic, resulting in the gravity energy storage device being unable to be directly connected to the grid. Because the mass of the heavy block is very large (tens of tons), a certain power disturbance will be generated during the process of the heavy block being put in or out in sequence, which will cause power quality problems. Second, the power generation power of a single channel of gravity energy storage is limited. Most of the current gravity energy storage power generation channels are in one channel, and at a certain moment only one heavy block drives the mechanical device and the generator to generate electricity. The output power of this channel is limited by the weight and descent speed of this single heavy block. Limited by the space, material and economy of the weight block, the weight of the weight block is limited to the order of tens of tons, and it is difficult to make a significant improvement; limited by the mechanical coupling device and the heavy weight bearing capacity, the running speed of the channel loaded with the weight block is limited to the single-digit m / s level, mostly around 1-2m / s, and it is difficult to make a qualitative improvement. The current method of increasing power generally uses multiple channels to cooperate in power generation, and uses the shaft system to couple the mechanical devices of multiple channels to jointly drive a high-power generator to generate electricity. However, the disadvantages of this method include: first, it increases the investment in equipment, resulting in an increase in the cost per unit power, resulting in poor economy; second, the complex shaft system coordination increases mechanical wear, resulting in a decrease in overall conversion efficiency. Third, in most schemes, the weight block bearing mechanism corresponds to the weight block one-to-one, and the flexible scheduling of the weight block cannot be achieved, the equipment utilization rate is low, and the bearing mechanism circulation efficiency is low.

[0005] In summary, the current gravity energy storage devices have the following problems: gravity energy storage circulation equipment cannot be deployed in scenarios with limited space; the gravity energy storage power generation scheme cannot achieve single-channel circulation; the power generation exhibits a "step-by-step, non-smooth" adjustment characteristic, which makes it impossible for the gravity energy storage device to be directly connected to the grid; the single-channel power generation power of gravity energy storage is limited, and at a certain moment there is only one weight block driving the mechanical device and the generator to generate electricity, which increases investment and mechanical equipment losses; the weight block bearing mechanism cannot achieve flexible scheduling of the weight block, resulting in low equipment utilization and low bearing mechanism circulation efficiency.

[0006] Therefore, it is necessary to design a gravity energy storage power generation and storage cycle device with a high duty cycle to solve the problems of gravity energy storage in scenarios with limited space. Summary of the invention

[0026] 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.

[0027] According to the present invention, a gravity energy storage power generation and storage cycle device with a high duty cycle is provided, such as Figures 1 to 4 As shown, the gravity energy storage power generation and storage cycle device with a high duty cycle can realize gravity energy storage cycle in a confined space. The gravity energy storage power generation and storage cycle device with a high duty cycle includes a conveying channel 1, a displacement channel 2 and a chain plate member 3.

[0028] In the following description, reference will be made to Figures 1 to 4 The detailed structures of the conveying channel 1, the displacement channel 2 and the chain plate member 3 of the gravity energy storage power generation and storage circulation device with a high duty cycle are specifically described.

[0029] like Figures 1 to 3 As shown, in the embodiment, the conveying channel 1 is used for the cyclic movement of the chain plate member 3, and the displacement channel 2 is used for the displacement of the weight block body 10, so that the weight block body 10 can be lifted from a low place to a high place or the weight block body 10 can be transported from a high place to a low place. The chain plate member 3 can be understood as a common bearing mechanism in a gravity energy storage device, which is used to bear the weight block body 10.

[0030] Understanding of "duty cycle": In a gravity energy storage channel such as a mine, since the space in the mine is very limited, how to lay out the gravity energy storage circulation channel is crucial, which is directly related to the power generation power and carrying energy of the channel. In the limited channel space, let the volume of the weight block body 10 occupy as much channel space as possible (i.e. duty cycle), improve space utilization, make energy utilization efficiency high, and thus improve the output power and energy level of the overall equipment. See Figure 5 , Figure 5 It is a top view of a typical circulation channel for gravity energy storage. The outermost thick solid line is the channel space (the power generation and storage channel 9 in the embodiment); a weight block bearing mechanism (the chain plate member 3 in the embodiment) is arranged along the inner wall of the power generation and storage channel 9, which is used to lift or lower the weight block body 10 and is connected to the transmission 8 of the motor 7 described below, and is then driven by the motor 7 or drives the motor 7 to store electricity. The rectangular cross-section in the middle part is the weight block body 10, which is the main energy and power unit of the circulation channel. In this way, Figure 5In the embodiment, the cross-sectional area of ​​the power generation and storage channel 9 is set to A, and the cross-sectional area of ​​the weight block body 10 with the largest cross-sectional area that can be installed is set to B, then the duty cycle N of the channel is: N=B / A×100%. In this way, if the duty cycle is larger, that is, the volume of the weight block body 10 occupies more channel space, the energy utilization efficiency can be higher. In order to enable the weight block bearing mechanism to reciprocate in the circulation channel, it is necessary to arrange other mechanisms such as conveying tracks in the circulation channel, but these mechanisms will occupy the channel space, resulting in a decrease in the duty cycle of the circulation channel. For this reason, the present invention provides a gravity energy storage power generation and storage circulation device with a high duty cycle, which can enable the power generation and storage channel 9 to have a higher duty cycle when these mechanisms are reasonably arranged.

[0031] Specifically, Figures 1 to 4 As shown, in the embodiment, the conveying channel 1 surrounds the displacement channel 2, see Figure 1 , here, surrounding can be understood as, since most of the device needs to be arranged in the power generation and storage channel 9, and the vertical projection of the power generation and storage channel 9 is formed into a rectangle, and in order to reserve enough displacement space for the weight block body 10, the conveying channel 1 is arranged on the left and bottom of the displacement channel 2 ( Figure 1 and Figure 2 The middle conveying channel 1 is arranged on the left side and bottom of the displacement channel 2. Figure 3 In another embodiment, the conveying channel 1 is arranged on the right side and bottom of the displacement channel 2).

[0032] Furthermore, the conveying channel 1 and the shifting channel 2 both include a chain condition 4 and a rotating wheel. Since the chain condition 4 and the rotating wheel are common structures and occupy a small space, the layout of the conveying channel 1 and the shifting channel 2 can make the shifting channel 2 have enough space, so that a larger weight block body 10 can be loaded in the shifting channel 2, thereby increasing the duty cycle and making the device have a "high duty cycle". The structure given in the embodiment can make the duty cycle 80%-90%.

[0033] Accordingly, since the conveying channel 1 occupies a small space, the fixed bearing mechanism commonly used in gravity energy storage in the prior art cannot be used, and a mechanism that can cyclically reciprocate in a small space and can carry a heavy object block body 10 with a large mass is required. In the embodiment, the bearing mechanism is a chain plate member 3, which can move together with the chain condition 4 and the rotating wheel member, and one side of the chain plate member 3 can be bent in a specific direction, while the other side cannot be bent and can carry a heavy object block body 10 with a large mass.

[0034] Furthermore, the wheel member is arranged at the end of the conveying channel 1 and the end of the displacement channel 2, and the chain member 4 surrounds the wheel member. In the embodiment, since the conveying channel 1 and the displacement channel 2 are arranged in a rectangular channel, the whole of the two can be understood as an approximately rectangular structure. In this way, the wheel member needs to be arranged at the four corners of the rectangular structure and the necessary bends to ensure that the chain member 4 can operate normally and drive the chain plate member 3 at the same time.

[0035] The chain plate member 3 is arranged on the chain condition 4, and the arrangement method can be, for example: the chain condition 4 can be a common chain with multiple links, and the front and rear ends of the chain plate member 3 can be installed at preset links (the front and rear ends here can be understood as the front and rear ends of the chain plate member 3 along its running direction. In fact, the chain plate member 3 is formed into a rectangular structure and can have four ends. In the direction of movement, the two relatively forward ends are the front ends, and the two relatively rearward ends are the rear ends). The installation method can be, for example, using an adapter to connect or other common fixed connection methods between the chain plate and the chain. There is no limitation here, as long as the chain plate member 3 can follow the movement of the chain condition 4.

[0036] When the chain plate 3 moves following the chain condition 4, the chain plate 3 can bend in the conveying channel 1. The bending here can be understood as that the chain plate 3 needs to pass through the rotating wheel when moving following the chain condition 4, so it needs to bend. It is mentioned above that one side of the chain plate 3 can be bent in a specific direction, while the other side cannot be bent, that is, the chain plate 3 can carry the weight block body 10 in the displacement channel 2 and drive the weight block body 10 to move from the loading position to the unloading position. Figure 1 and Figure 2 Since the gravity energy storage power generation and storage cycle device with a high duty cycle has a power storage state and a power generation state, the loading position and the unloading position are not fixed. Figure 1 In the power storage state shown in FIG. 1 , the position of the weight block body 10 at the bottom is the loading position, and the position of the weight block body 10 at the top is the unloading position. Figure 2 In the power generation state shown, the position of the weight block body 10 at the top is the loading position, and the position of the weight block body 10 at the bottom is the unloading position. Figures 1 to 3The chain plate member 3 moves in the direction indicated by the middle arrow. In the conveying channel 1, the chain plate member 3 can bend to achieve reciprocating motion. In the displacement channel 2, the chain plate member 3 cannot be bent and can only remain relatively straight to carry the weight block body 10. In addition, since the chain plate member 3 circulates inside the conveying channel 1 and does not interfere with the displacement channel 2 of the weight block body 10, the chain member 4 can drive the rotating wheel member so that the motor 7 can emit or receive a stable current accordingly, whether in the process of power generation or power storage, so that the gravity energy storage power generation and storage circulation device with a high duty cycle can be directly integrated into the power grid for power generation. Also, since the chain plate member 3 circulates inside the conveying channel 1, the problem of low circulation efficiency of the bearing mechanism in the original technology is also solved.

[0037] In the embodiment, since the conveying channel 1 can be equipped with multiple chain plate members 3, the problem of limited power generation in a single gravity energy storage channel, where only one weight block drives the mechanical device and the generator to generate electricity at a certain time, is also solved. The gravity energy storage power generation and storage cycle device with a high duty cycle can be used to sequentially shift multiple weight block bodies 10 in one channel, thereby improving the utilization rate of the equipment.

[0038] The gravity energy storage power generation and storage circulation device with a high duty cycle can realize the movement of the heavy object block body 10 in a confined space through the cooperation of the conveying channel 1, the displacement channel 2 and the chain plate member 3, thereby realizing the power generation and storage of gravity energy; because the conveying channel 1 surrounds the displacement channel 2, the space occupied by the conveying channel 1 can be reduced while the space occupied by the displacement channel 2 can be increased, so that the displacement channel 2 can lift the heavy object block body 10 with a larger volume, thereby realizing high duty cycle transportation and improving energy utilization efficiency and power generation power; the conveying channel 1, the displacement channel 2 and the chain plate member 3 are formed into an integrated design, avoiding the need for the original structure to set up a circulation channel of the bearing mechanism separately, saving space and occupying The utility model reduces the land investment and realizes the intensive design, which is particularly suitable for the scene with limited space. At the same time, it also solves the problem that the gravity energy storage power generation scheme cannot realize single-channel circulation. Since the loading and unloading of the chain plate member 3 and the weight block body 10 are always in a stable state during the power generation and storage process, the gravity energy storage power generation and storage cycle device with a high duty cycle can be directly connected to the power grid, so that the power generation is stable and smooth. Since the transmission channel 1 and the displacement channel 2 move relatively independently, the problem that the power generation power of the single-channel gravity energy storage in the original structure is limited and there is only one weight block driving the mechanical device and the generator to generate electricity at a certain moment is solved. At the same time, it also solves the problems of low equipment utilization and low circulation efficiency of the bearing mechanism.

It is mentioned above that "the conveying channel 1 and the displacement channel 2 are arranged in a rectangular channel, so the two can be understood as approximately rectangular structures, so the wheel member needs to be arranged at the four corners of the rectangular structure", so the first wheel 501 and the second wheel 502 can be understood as wheels arranged at the four corners of the rectangular channel, and simultaneously connect the conveying channel 1 and the displacement channel 2. In order to facilitate the acceptance or unloading of the heavy object block body 10, the setting position of the second wheel 502 can be understood as a position extending outward from one of the four corners of the rectangular channel.

The first track 601 and the second track 602 can both be composed of a plurality of conveying rollers connected together, and the conveying rollers can transport and support the weight block body 10. The layout of these tracks is prior art and will not be described in detail here.

[0042] Preferably, if Figure 1 and Figure 2As shown, in one embodiment, the first rotating wheel 501, the sixth rotating wheel 506 and the third rotating wheel 503 are arranged in sequence along the vertical direction. These three rotating wheels enable the chain element 4 to move in different horizontal planes. Figure 3 As shown, the second rotating wheel 502 is connected to the second track 602. Figure 3 In the second embodiment shown, the first rotating wheel 501, the sixth rotating wheel 506 and the second rotating wheel 502 are arranged in sequence along the vertical direction.

[0043] Preferably, Figure 3 In the second embodiment shown in Figure 1 and Figure 2 The difference of the first embodiment shown is that the first track 601 and the second track 602 are arranged at different positions. Figure 1 and Figure 2 As shown, in the first embodiment, the first track 601 and the second track 602 are arranged in a staggered manner. Figure 3 As shown, in the second embodiment, the first track 601 is located on top of the second track 602. The user can select a suitable layout method according to the actual construction environment.

[0044] Preferably, if Figure 1 and Figure 2 The figure shows a side view of the gravity energy storage power generation and storage cycle device with a high duty cycle. In the embodiment, the chain condition 4 includes a first chain and a second chain. In actual use, the number of the six wheels of the first wheel 501, the second wheel 502, the third wheel 503, the fourth wheel 504, the fifth wheel 505 and the sixth wheel 506 can all be two, and two corresponding wheels form a pair. Figures 1 to 3 Shown in the figure are a first rotating wheel 501, a second rotating wheel 502, a third rotating wheel 503, a fourth rotating wheel 504, a fifth rotating wheel 505 and a sixth rotating wheel 506. For the convenience of description, the six rotating wheels, each of which is one, are called one group, and the other six rotating wheels are called the second group. The two groups of rotating wheels together constitute the conveying channel 1 and the shifting channel 2. Each group of rotating wheels is driven by a chain condition 4 respectively. It is mentioned above that "in fact, the chain plate member 3 is formed into a rectangular parallelepiped structure and can have four ends. In the direction of movement, the two relatively forward ends are the front ends, and the two relatively backward ends are the rear ends." In order to correspond to the two groups of rotating wheels, a front end and a corresponding rear end of the chain plate member 3 are arranged on the chain condition 4 of the first group of rotating wheels, and the other front end and the corresponding other rear end of the chain plate member 3 are arranged on the chain condition 4 of the second group of rotating wheels.

Specifically, the first chain surrounds the first rotating wheel 501, the third rotating wheel 503, the second rotating wheel 502 and the sixth rotating wheel 506, and the second chain surrounds the first rotating wheel 501, the third rotating wheel 503, the second rotating wheel 502, the fourth rotating wheel 504 and the fifth rotating wheel 505. It should also be noted here that, in fact, in order to make the two chains move together and not interfere with each other, the same rotating wheel (for example, the first rotating wheel 501, the third rotating wheel 503 and the second rotating wheel 502) around which the two chains are surrounded can be a gear set composed of multiple gears, for example: two gears are simultaneously passed through a rotating shaft, and the two gears are used to surround the first chain and the second chain respectively. As mentioned above, the number of the six wheels, namely, the first wheel 501, the second wheel 502, the third wheel 503, the fourth wheel 504, the fifth wheel 505 and the sixth wheel 506, can all be two. Accordingly, the number of the first chain and the second chain can also be two. In other words, Figures 1 to 3 The structure shown is half of the device, and the other half is the same as the structure shown.

[0046] Furthermore, in order to enable the chain plate member 3 to be transported in the conveying channel 1 and to carry the weight block body 10 in the displacement channel 2, the front end of the chain plate member 3 (i.e., the relatively forward end in the direction of movement mentioned above) is connected to the first chain, and the rear end of the chain plate member 3 is connected to the second chain. In this way, during the movement of the chain plate member 3, the two ends of the chain plate member 3 can move with the first chain and the second chain respectively. Figure 1For example, the movement will be described. When the link plate member 3 is located in the conveying channel 1, both ends of the link plate member 3 can respectively follow the first chain and the second chain and move around the first runner 501, the third runner 503 and the second runner 502, thereby realizing cyclic reciprocation; when the link plate member 3 is located in the shifting channel 2, the front end of the link plate member 3 follows the first chain to reach the sixth runner 506, and the rear end of the link plate member 3 follows the second chain to reach the fourth runner 504. At this time, the link plate member 3 cannot be bent, and the link plate member 3 is driven by the force jointly applied by the first chain and the second chain and is lifted along the shifting channel 2. It should be noted that it is mentioned above that "the first chain and the second chain can be arranged side by side and surround their respective runners". Therefore, when the first chain and the second chain are arranged side by side, the front end and the rear end of the link plate member 3 can both use, for example, an adapter formed in a "C" shape. The "C" shaped adapter can include a first side, a second side and a connecting edge connecting the two sides. The first side can be connected to the end of the link plate member 3, and the second side is connected to the first chain or the second chain. When the first chain and the second chain are arranged side by side, the connecting edge can enable the end of the link plate member 3 to cross one of the chains and be directly connected to the other chain to avoid interference.

[0047] Preferably, as Figures 1 to 3 shown, in the embodiment, the gravity energy storage power generation and storage cycle device with a high duty ratio further includes a power generation and storage unit, and the power generation and storage unit can include a motor 7 and a transmission 8. The motor 7 is connected to the runner member through the transmission 8. Since the first chain surrounds the first runner 501, the third runner 503, the second runner 502 and the sixth runner 506, and the second chain surrounds the first runner 501, the third runner 503, the second runner 502, the fourth runner 504 and the fifth runner 505, therefore, the transmission 8 can be connected to any one of the first runner 501, the third runner 503 and the second runner 502 that are jointly surrounded by the first chain and the second chain. Both the motor 7 and the transmission 8 can be common devices in gravity energy storage and will not be elaborated here.

[0048] Preferably, as Figures 1 to 3 shown, in the embodiment, the gravity energy storage power generation and storage cycle device with a high duty ratio is used for the power generation and storage channel 9 (the power generation and storage channel 9 can be understood as an abandoned mine with limited space, etc.), and the shifting channel 2 is arranged in the power generation and storage channel 9. In order to increase the duty ratio, the shifting channel 2 needs to occupy as much of the power generation and storage channel 9 as possible. And in order to realize the circulation of the link plate member 3, the conveying channel 1 needs to partially extend out of the power generation and storage channel 9 and be docked with the second track 602 at the same time. However, this part of the conveying channel 1 that extends out of the power generation and storage channel 9 does not affect the duty ratio.

[0049] Preferably, as Figure 4As shown, in the embodiment, the chain plate member 3 may include a chain plate link 301, a connector 302 and a plate body 303. There are multiple chain plate links 301, two adjacent chain plate links 301 are connected by the connector 302, the chain plate link 301 surrounds the rotating wheel member (for example, the second rotating wheel 502), and the plate body 303 is arranged on the side of the chain plate link 301 facing away from the rotating wheel member. A part of the plate body 303 is located outside the chain plate link 301 and abuts against another adjacent chain plate link 301, so that the chain plate member 3 can be bent in a specific direction, while the other side cannot be bent and can carry a heavy block body 10 with a large mass.

[0050] by Figure 1 Taking the power storage process shown as an example, the cyclic motion process of the gravity energy storage power generation and storage cycle device with a high duty cycle is: the chain plate member 3 follows the first chain and the second chain to move in the direction indicated by the arrow in the figure. The chain plate member 3 is in the conveying channel 1. Since it is in a specific direction, it can be bent. The chain plate member 3 cannot be bent in the displacement channel 2. At this time, it can drive the weight block body 10 transmitted from the second track 602 and lift the weight block body 10 in the vertical upward direction. Here, the contact mode of a weight block body 10 and a chain plate member 3 can be, for example, as follows: when the chain plate member 3 moves to the position of the second rotating wheel 502, the weight block body 10 is simultaneously transported to the second rotating wheel 502 via the second track 602, and the weight block body 10 contacts the chain plate member 3 on the second rotating wheel 502, and the two then move together to the displacement channel 2. The weight block body 10 lifted from the bottom to the top of the displacement channel 2 is driven by the chain plate member 3 to move to the first rotating wheel 501. At this time, the chain plate member 3 is separated from the weight block body 10, and the weight block body 10 continues to move along the first track 601. The chain plate member 3 returns to the position of the second rotating wheel 502 via the conveying channel 1 to receive the next weight block body 10. In addition, the gravity energy storage power generation and storage cycle device with a high duty cycle can have multiple chain plate members 3 at the same time. Multiple chain plate members 3 can be used for the displacement of multiple weight block bodies 10 to realize the storage of multiple weight block bodies 10 in the power generation and storage channel 9 at the same time, thereby improving efficiency.

[0051] The gravity energy storage power generation and storage circulation device with a high duty cycle can realize the movement of the heavy object block body in a confined space through the cooperation of the conveying channel, the displacement channel and the chain plate member, thereby realizing the power generation and storage of gravity energy; because the conveying channel surrounds the displacement channel, the space occupied by the conveying channel can be reduced while the space occupied by the displacement channel can be increased, so that the displacement channel can lift the heavy object block body with a larger volume, thereby realizing high duty cycle transportation and improving energy utilization efficiency and power generation power; the conveying channel, the displacement channel and the chain plate member are formed into an integrated design, avoiding the need for the original structure to set up a circulation channel of the bearing mechanism separately, saving space and occupied area, and reducing It reduces land investment and realizes intensive design, which is particularly suitable for scenarios with limited space. It also solves the problem that the gravity energy storage power generation scheme cannot achieve single-channel circulation. Since the loading and unloading of the chain plate and the weight block body are always in a stable state during the power generation and storage process, the gravity energy storage power generation and storage cycle device with a high duty cycle can be directly connected to the power grid, making the power generation stable and smooth. Since the transmission channel and the displacement channel move relatively independently, the problem of limited power generation power of the single-channel gravity energy storage in the original structure and only one weight block driving the mechanical device and the generator to generate electricity at a certain moment is solved. At the same time, the problems of low equipment utilization and low circulation efficiency of the load-bearing mechanism are also solved.
