Description

Technical Field

[0001] The present application relates to the field of gravity energy storage technology, and in particular to a gravity energy storage device with the function of loading and unloading heavy objects without stopping operation. 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] The existing gravity energy storage devices have the following problems: First, the existing gravity energy storage power generation scheme cannot achieve a non-stop cycle. Whether loading or unloading heavy blocks, loading and unloading time is required, which causes the front-end mechanical input device connected to the generator to start and stop from time to time. Each start and stop will have a large impact on the output power, making the charging or discharging power of the gravity energy storage 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. In addition, since the mass of the heavy block is very large, usually tens of tons, and the process of the heavy block being put in and out in sequence will produce certain power disturbances, 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 heavy block, the weight of the heavy block is limited to tens of tons, and it is difficult to increase it significantly; limited by the mechanical coupling device and the heavy weight carrying capacity, the running speed of the channel loaded with heavy blocks is limited to the single-digit m / s level, mostly around 1-2m / s, and it is difficult to improve it qualitatively. 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 high-power generators 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.

[0004] In summary, the current gravity energy storage devices have the problems of being unable to generate electricity continuously and stably, low power generation of single-channel gravity energy storage and difficulty in increasing power generation, large mechanical losses and high costs.

[0005] Therefore, it is necessary to design a circulation device for gravity energy storage and continuous and stable power generation to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0022] 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.

[0023] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the application is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0024] 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.

[0025] 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.

[0026] According to the present invention, a gravity energy storage device with the function of loading and unloading heavy objects without stopping operation is provided, such as Figures 1 to 5 As shown, the gravity energy storage device with the function of loading and unloading heavy objects without stopping operation can load and unload the following heavy object body 203 during power generation and energy storage without stopping the device. The gravity energy storage device with the function of loading and unloading heavy objects without stopping operation includes a transport module 1 and a loading and unloading module 2.

[0027] In the following description, reference will be made to Figures 1 to 5 The detailed structures of the transport module 1 and the loading and unloading module 2 of the gravity energy storage device with the function of loading and unloading heavy objects without stopping operation are described in detail.

[0028] like Figure 1 Combined with Figure 2As shown, in the embodiment, the weight block body 203 can be loaded and unloaded in the loading and unloading module 2, and the weight block body 203 can be shifted in the transport module 1. The transport module 1 may include a rotating wheel, a chain member 101 and a bearing mechanism 102. The bearing mechanism 102 is arranged on the chain member 101, and the arrangement method may be, for example, a pin connection. When the chain member 101 moves, the bearing mechanism 102 can move together with the chain member 101. The rotating wheel is arranged at the end of the transport module 1, and the chain member 101 can rotate around the rotating wheel. The rotating wheel can be understood as a component that assists the movement of the chain member 101, and can also play a limiting role. The chain member 101 can surround the rotating wheel to keep moving. The maintaining movement here can be understood as that, since the bearing mechanism 102 is used to bear the weight block body 203, and the weight block body 203 is affected by gravity, it can drive the bearing mechanism 102 and the chain condition 101 to move together. At this time, regardless of whether the other bearing mechanisms 102 bear the weight block body 203, the chain condition 101 can always be in operation due to being driven by the previous weight block body 203. Since the three parts of the rotating wheel, the chain condition 101 and the bearing mechanism 102 can circulate independently, and the chain condition 101 can always be in operation, the transport module 1 can generate stable and continuous electric energy when generating electricity, so that the power generation system can always generate electricity at a synchronous speed and can be directly connected to the power grid.

[0029] Further, the loading and unloading module 2 may include a transport channel 201, a support mechanism 202 and a weight block body 203, wherein the weight block body 203 is the above-mentioned weight block body 203. The support mechanism 202 is disposed on the transport channel 201, and the weight block body 203 is disposed on the support mechanism 202 driven by the transport channel 201, and the support mechanism 202 and the carrying mechanism 102 can be coupled or decoupled to drive the weight block body 203 to separate or connect with the support mechanism 202.

[0030] See also Figure 3 , Figure 3 The diagram includes three states separated by horizontal dotted lines. For ease of description, they are the first state, the second state, and the third state from top to bottom. Figure 3The left arrow in the middle represents the movement of the bearing mechanism 102 from top to bottom, that is, it is in a downward movement, and the downward movement is used for unloading the weight block body 203. The unloading process of the corresponding weight block body 203 (the weight block body 203 moves from top to bottom), that is, the unloading process of the weight block body 203 is from the first state to the second state and then to the third state. In the first state, the bearing mechanism 102 carrying the weight block body 203, due to the influence of the gravity of the weight block body 203, drives the chain condition 101 and the bearing mechanism 102 to move downward and approach the support mechanism 202. In the second state, the bearing mechanism 102 is coupled with the support mechanism 202, and the support mechanism 202 and the bearing mechanism 102 jointly support the weight block body 203. In the third state, the bearing mechanism 102 continues to move downward due to the traction of the chain condition 101, the bearing mechanism 102 is decoupled from the support mechanism 202, and the bearing mechanism 102 is separated from the weight block body 203, completing the unloading of the weight block body 203. In addition, coupling can be understood as the connection between the bearing mechanism 102 and the support mechanism 202, and decoupling can be understood as the separation between the bearing mechanism 102 and the support mechanism 202. The unloading of the weight block body 203, that is, the process of the weight block body 203 being in a downward motion, can realize the power generation of the gravity energy storage device.

[0031] Figure 3 The arrow on the right side in the middle represents the movement of the bearing mechanism 102 from bottom to top, that is, it is in an ascending motion. The ascending motion is used for loading the weight block body 203, corresponding to the loading process of the weight block body 203 (the weight block body 203 moves from bottom to top), that is, the unloading process of the weight block body 203 from the third state to the second state and then to the first state. In the third state, the weight block body 203 located on the support mechanism 202 is ready to be loaded on the bearing mechanism 102. The bearing mechanism 102 needs to be coupled with the support mechanism 202 at this time. The bearing mechanism 102 continues to move upward to approach the support mechanism 202 through the drive of the chain condition 101. In the second state, the bearing mechanism 102 is coupled with the support mechanism 202. At this time, the bearing mechanism 102 abuts against the weight block body 203, and the support mechanism 202 and the bearing mechanism 102 jointly support the weight block body 203. In the first state, the bearing mechanism 102 carries the weight block body 203 and continues to move upward driven by the chain condition 101. At this time, the bearing mechanism 102 is decoupled from the support mechanism 202, and the weight block body 203 is separated from the support mechanism 202, completing the loading of the weight block body 203. The loading of the weight block body 203, that is, the process in which the weight block body 203 is in an upward motion, can realize the energy storage of the gravity energy storage device.

[0032] The gravity energy storage device with the function of loading and unloading heavy objects without stopping operation can load and unload the heavy object body 203 during the process of power generation and energy storage without stopping the device through the cooperation of the transport module 1 and the loading and unloading module 2. At the same time, since the rotating wheel and the chain condition 101 can always be in motion, the transport module 1 can generate stable and continuous electric energy when generating electricity, so that the power generation system can always generate electricity at a synchronous speed and can be directly connected to the power grid. Through the coupling and decoupling of the bearing mechanism 102 and the supporting mechanism 202, the rapid loading and unloading of the heavy object body 203 can be achieved, and the power generation power is increased without the need for additional equipment, and the mechanical loss and cost are reduced.

[0033] Preferably, if Figure 1 , Figure 3 and Figure 5 As shown, in the embodiment, the support mechanism 202 may include a plurality of first support rollers 204, the spacing between two adjacent first support rollers 204 is a first gap, the bearing mechanism 102 may include a mechanism body 110 and a plurality of second support rollers 103 disposed on the mechanism body 110, the spacing between the plurality of second support rollers 103 is a second gap, one second support roller 103 can be disposed in one first gap, and one first support roller 204 can be disposed in one second gap. The plurality of first support rollers 204 are not limited to Figure 3 The four support rollers given in the figure may also include two, three or more, as long as the weight block body 203 can be transported from the transport channel 201 to the support mechanism 202. The method of transporting from the transport channel 201 to the support mechanism 202 is not limited. For example, support rollers may be laid all over the transport channel 201, and the spacing between these support rollers is the first gap. Alternatively, the support rollers may be hoisted to multiple first support rollers 204 by a car-type mechanism or a top gantry-type mechanism. The support mechanism 102 may be, for example, a fork similar to a forklift (such as Figure 5 As shown in the figure, the main body 110 includes a mechanism body 110 and a plurality of second support rollers 103 arranged on the main body 110. The second support rollers 103 can be the "forks" of the fork, which play the role of supporting the weight block body 203. In actual use, the main body 110 is located on the side of the first support roller 204 and does not interfere with the first support roller 204. It plays a supporting and positioning role for the first support roller 204. Only the second support roller 103 and the first support roller 204 perform coupling and decoupling movements. In this way, the loading and unloading of the weight block body 203 can be achieved through the cooperation of the bearing mechanism 102 similar to the fork structure and the plurality of first support rollers 204 spaced apart from each other.

[0034] Preferably, if Figure 1 and Figure 2As shown, in the embodiment, the rotating wheel member includes a first rotating wheel 106 and a second rotating wheel 107, and the first rotating wheel 106 and the second rotating wheel 107 are respectively arranged at two ends of the transport module 1. The first rotating wheel 106 and the second rotating wheel 107 can respectively limit the two ends of the chain condition 101.

[0035] Preferably, if Figure 1 and Figure 2 As shown, in the embodiment, the loading and unloading module 2 may include a first area 205, a second area 206, a third area 207 and a fourth area 208. The first rotating wheel 106 has the first area 205 and the second area 206 on both sides in the first direction, and the second rotating wheel 107 has the third area 207 and the fourth area 208 on both sides in the first direction. The first direction here can be understood as Figure 1 and Figure 2 The first area 205 and the third area 207 and the second area 206 and the fourth area 208 are arranged to intersect.

[0036] Preferably, if Figure 1 and Figure 2 As shown, in the embodiment, when the gravity energy storage device with the function of non-stop loading and unloading of heavy objects is in the process of generating electricity, the supporting mechanism 102 loads the heavy object block body 203 in the first area 205 and the second area 206, and the supporting mechanism 102 unloads the heavy object block body 203 in the third area 207 and the fourth area 208; the supporting mechanism 102 can drive the heavy object block body 203 located in the first area 205 to move to the third area 207 or the supporting mechanism 102 can drive the heavy object block body 203 located in the second area 206 to move to the fourth area 208. Due to the influence of the movement of the chain condition 101, in order to realize the non-stop loading and unloading of the heavy object block body 203, it is necessary to transport the heavy object block body 203 to the corresponding intersection position, and the intersection position here can be understood as Figure 2 In the vertical projection of , the first area 205 and the third area 207 are at the intersection position.

[0037] Preferably, if Figure 1 and Figure 2As shown, in the embodiment, the transport module 1 may further include a commutator 104 and a generator 105, the generator 105 is connected to the rotating wheel through the commutator 104, and the rotating wheel is driven by the commutator 104 to change the direction of rotation. In actual use, the gravity energy storage device with the function of loading and unloading heavy objects without stopping can have two moving parts, that is, by changing the movement direction of the chain condition 101, the heavy object block body 203 in the first area 205 can move to the third area 207 or the heavy object block body 203 in the second area 206 can move to the fourth area 208 when generating electricity. In this way, the user can perform scheduling in different areas as needed. For example, if the number of heavy object block bodies 203 in the first area 205 is large, the chain condition 101 can rotate clockwise for a long time, and if the number of heavy object block bodies 203 in the second area 206 is large, the chain condition 101 can rotate counterclockwise for a long time, thereby meeting the needs of power generation and scheduling.

[0038] Preferably, if Figure 1 As shown, in the embodiment, the rotating wheel member includes a first transmission part 108 and a second transmission part 109. In vertical projection, the rotating wheel member can be formed as a circular member, and the first transmission part 108 and the second transmission part 109 are respectively half of the circular member, that is, the first transmission part 108 and the second transmission part 109 can both be formed as semicircular members, and the first transmission part 108 is located at the upper part of the second transmission part 109. The transport channel 201 can be arranged at the connection between the first transmission part 108 and the second transmission part 109. Such an arrangement can make the weight block body 203 dock with the bearing mechanism 102 at the outermost side of the rotating wheel member formed as a circular member. In other words, the weight block body 203 needs to be docked with the bearing mechanism 102 within the effective length of the chain condition 101. The effective length here can be understood as the part of the chain condition 101 that moves in the vertical direction. If there are multiple transport channels 201, the highest position of the multiple transport channels 201 in the vertical direction is the connection between the first transmission part 108 and the second transmission part 109, and the remaining transport channels 201 are arranged in sequence downward in the vertical direction.

[0039] Preferably, if Figure 1 As shown, in the embodiment, the first area 205, the second area 206, the third area 207 and the fourth area 208 each include a plurality of transport channels 201. The plurality of transport channels 201 are respectively provided in the four areas to simultaneously transport a plurality of weight block bodies 203 to achieve high power generation.

[0040] Preferably, in the embodiment, in order to ensure that the gravity energy storage device with the function of loading and unloading heavy objects can operate normally, it is necessary to calculate the number of weight block bodies 203 that can be carried at the same time according to the various structures of the gravity energy storage device with the function of loading and unloading heavy objects. Specifically, the vertical effective length of the chain condition 101 is set to L. For ease of understanding, the numerical effective length can be understood as Figure 1 The distance between the top transport channel 201 and the bottom transport channel 201. The linear speed of the chain condition 101 is V, the loading time of each weight block body 203 is T, and the number of weight block bodies 203 that can be simultaneously carried by the gravity energy storage device with the function of non-stop loading and unloading of weight blocks is N, then N=L / V / T.

[0041] Preferably, in the embodiment, the mass of each weight block body 203 is set to m, and the output power of the gravity energy storage device with the function of non-stop loading and unloading of weight blocks is P, then P=N×m×g×V, g is the acceleration of gravity. If the gravity energy storage device with the function of non-stop loading and unloading of weight blocks includes multiple transport channels 201, then the output power P=N×m×g×V×the number of transport channels 201. It should be noted that the number of transport channels 201 here refers to the number of transport channels 201 in one area, and the four areas correspond to each other. For example, Figure 1 Two transport channels 201 within the first area 205.

[0042] The operation process of the gravity energy storage device with the function of loading and unloading heavy objects without stopping is as follows: Figure 4 Taking the power generation process of the weight block body 203 moving from the first area 205 to the third area 207 as an example, after the weight block body 203 is transported through the transport channel 201 and arrives at the coupling position of the first area 205, the chain condition 101 directly drives the weight block body 203 to enter the transport module 1, and the process of loading the weight block body 203 does not require other actuators. After the weight block body 203 passes through the rotating wheel, it drives the chain condition 101 to move at a uniform speed through its own gravity, thereby driving the generator 105 to generate electricity. Uniform motion can be understood as: after the first weight block body 203 moves from the first area 205 to the third area 207, it is already in the power generation process, and the chain condition 101 is driven. Since the weight of each weight block body 203 is consistent, the movement of the chain condition 101 gradually approaches uniform speed. In addition, uniform rotation can also be artificially controlled by a controller, which can be achieved by, for example, driving a speed regulator through a controller, so that the period approaching uniform rotation is shortened. After the weight block body 203 reaches the coupling position of the third area 207, no other actuators are needed, and the weight block body 203 can enter the transport channel 201 without the chain condition 101 stopping and the running speed remains unchanged, thereby continuing to the next cycle.

[0043] The gravity energy storage device with the function of loading and unloading heavy objects without stopping operation can load and unload the heavy object body without stopping the device during the process of power generation and energy storage through the cooperation of the transportation module and the loading and unloading module. At the same time, since the rotating wheel and the chain conditions can always be in a state of motion, the transportation module can generate stable and continuous electric energy when generating electricity, so that the power generation system can always generate electricity at a synchronous speed, can be directly connected to the power grid, and can also solve the scheduling problem of the original bearing device, simplify the system, reduce the system complexity, and improve the robustness of the system operation. Through the coupling and decoupling of the bearing mechanism and the supporting mechanism, the rapid loading and unloading of the heavy object body can be achieved, and the additional loading and unloading device can be omitted. Without the need for additional equipment, the power generation capacity is increased, the operating efficiency is improved, and the mechanical loss and cost are reduced.
