Description

Technical Field

[0001] This application relates to the technical field of gravity energy storage, and in particular to a gravity energy storage device with the function of loading and unloading heavy blocks without power interruption. 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 then lowered to drive a generator to generate electricity.

[0003] Existing gravity energy storage devices have the following problems: First, the existing gravity energy storage power generation schemes cannot achieve a non-stop cycle. Whether loading or unloading heavy blocks, loading and unloading times are required, which results in the start and stop of the front-end mechanical input device connected to the generator. Each start and stop will have a large impact on the output power, making the charging or discharging power of gravity energy storage show a "stepped, non-smooth" regulation characteristic, resulting in the inability of the gravity energy storage device to be directly connected to the grid. In addition, due to the large mass of the heavy blocks, usually dozens of tons, and the process of sequential input and output of the heavy blocks will generate a certain power disturbance, which will cause power quality problems. Second, the single-channel power generation of gravity energy storage is limited. In most current gravity energy storage power generation channels, at a certain moment, only one heavy block drives the mechanical device and the generator to generate electricity in one channel. The output power of this channel is limited by the weight and falling speed of this single heavy block. Limited by the space, material and economy of the heavy blocks, the weight of the heavy blocks is limited to the order of dozens of tons and it is difficult to have a large increase; limited by the mechanical coupling device and the large weight bearing capacity, the running speed of the channel for loading heavy blocks is limited to the order of single-digit m / s, mostly around 1-2 m / s, and it is difficult to have a qualitative improvement. The existing methods for increasing power generally use multiple channels to cooperate in power generation, and use a 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: one is that it increases the investment in equipment, resulting in an increase in the cost per unit power and a deterioration in economy; the other is the complex shaft system coordination, which increases mechanical wear and reduces the overall conversion efficiency.

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

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

Detailed implementation manners

[0026] 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. Apparently, the described embodiments are only a part rather than all of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein 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 present application claimed, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0027] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationships indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, or the orientation or positional relationships in which the products of this application are customarily placed during use. These are 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 differential description and should not be construed as indicating or implying relative importance.

[0028] 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.

[0029] In the description of the embodiments of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "install", "connect", "couple" 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 connection inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0030] According to a gravity energy storage device with the function of loading and unloading heavy object blocks without stopping operation provided by the present invention, as Figures 1 to 5 shown, the gravity energy storage device with the function of loading and unloading heavy object blocks without stopping operation can load and unload the following heavy object block body 203 during the processes of power generation and energy storage without stopping the operation of the device. The gravity energy storage device with the function of loading and unloading heavy object blocks without stopping operation includes a transportation module 1 and a loading and unloading module 2.

[0031] In the following description, reference will be made to Figures 1 to 5 specifically describe the detailed structures of the transportation module 1 and the loading and unloading module 2 of the gravity energy storage device with the function of loading and unloading heavy object blocks without stopping operation.

[0032] As Figure 1 and in combination with Figure 2As shown, in the embodiment, the heavy object block body 203 can be loaded and unloaded in the loading and unloading module 2, and the heavy object block body 203 can be displaced in the transportation module 1. The transportation module 1 may include a runner member, a chain member 101, and a bearing mechanism 102. The bearing mechanism 102 is arranged on the chain member 101, and the arrangement method can be, for example, using a pin shaft connection. When the chain member 101 moves, the bearing mechanism 102 can move together with the chain member 101. The runner member is arranged at the end of the transportation module 1, and the chain member 101 can rotate around the runner member. The runner member 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 rotate around the runner member to maintain movement. Here, maintaining movement can be understood as follows: Since the bearing mechanism 102 is used to bear the heavy object block body 203, and the heavy object block body 203 is affected by gravity and can drive the bearing mechanism 102 and the chain member 101 to move together. At this time, regardless of whether the other bearing mechanisms 102 bear the heavy object block body 203, the chain member 101 can always be in an operating state due to the drive of the previous heavy object block body 203. Since the runner member, the chain member 101, and the bearing mechanism 102 can operate independently in a cycle, and the chain member 101 can always be in an operating state, the transportation module 1 can generate stable and continuous electrical 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.

[0033] Further, the loading and unloading module 2 may include a transportation channel 201, a support mechanism 202, and the heavy object block body 203, where the heavy object block body 203 is the above-mentioned heavy object block body 203. The support mechanism 202 is arranged on the transportation channel 201, and the heavy object block body 203 is arranged on the support mechanism 202 driven by the transportation channel 201. The support mechanism 202 and the bearing mechanism 102 can be coupled or decoupled to drive the heavy object block body 203 to separate from or connect to the support mechanism 202.

[0034] See Figure 3 , Figure 3 which includes three states separated by a horizontal dotted line. For the convenience of description, from top to bottom, they are the first state, the second state, and the third state. Figure 3The left arrow in the middle represents the downward movement of the carrying mechanism 102, that is, in the descending motion, and the descending motion is used for unloading the heavy object body 203. Corresponding to the unloading process of the heavy object body 203 (the heavy object body 203 moves from top to bottom), that is, the unloading process of the heavy object body 203 is from the first state to the second state and then to the third state. In the first state, the carrying mechanism 102 carrying the heavy object body 203, due to the influence of the gravity of the heavy object body 203, drives the chain condition 101 and the carrying mechanism 102 to move downward and approach the support mechanism 202. In the second state, the carrying mechanism 102 is coupled with the support mechanism 202, and the support mechanism 202 and the carrying mechanism 102 jointly support the heavy object body 203. In the third state, due to the traction of the chain condition 101, the carrying mechanism 102 continues to move downward, the carrying mechanism 102 is decoupled from the support mechanism 202, and the carrying mechanism 102 is separated from the heavy object body 203, completing the unloading of the heavy object body 203. In addition, coupling can be understood as the carrying mechanism 102 and the support mechanism 202 being connected to each other, and decoupling can be understood as the carrying mechanism 102 and the support mechanism 202 being separated from each other. The unloading of the heavy object body 203, that is, the process in which the heavy object body 203 is in the descending motion, can generate electricity for the gravity energy storage device.

[0035] Figure 3 The right arrow in the middle represents the upward movement of the carrying mechanism 102, that is, in the ascending motion, and the ascending motion is used for loading the heavy object body 203. Corresponding to the loading process of the heavy object body 203 (the heavy object body 203 moves from bottom to top), that is, the unloading process of the heavy object body 203 is from the third state to the second state and then to the first state. In the third state, the heavy object body 203 located on the support mechanism 202 is ready to be loaded onto the carrying mechanism 102. At this time, the carrying mechanism 102 needs to be coupled with the support mechanism 202, and the carrying mechanism 102 continues to move upward to approach the support mechanism 202 under the drive of the chain condition 101. In the second state, the carrying mechanism 102 is coupled with the support mechanism 202. At this time, the carrying mechanism 102 abuts against the heavy object body 203, and the support mechanism 202 and the carrying mechanism 102 jointly support the heavy object body 203. In the first state, the carrying mechanism 102 carries the heavy object body 203 and continues to move upward under the drive of the chain condition 101. At this time, the carrying mechanism 102 is decoupled from the support mechanism 202, and the heavy object body 203 is separated from the support mechanism 202, completing the loading of the heavy object body 203. The loading of the heavy object body 203, that is, the process in which the heavy object body 203 is in the ascending motion, can store energy for the gravity energy storage device.

[0036] The gravity energy storage device with the function of loading and unloading heavy objects without stopping can load and unload the heavy object body 203 without stopping the device during the power generation and energy storage processes through the cooperation of the transportation module 1 and the loading and unloading module 2. At the same time, since the runner part and the chain condition 101 can always be in a moving state, the transportation module 1 can generate stable and continuous electric energy during power generation, 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 support mechanism 202, the rapid loading and unloading of the heavy object body 203 can be realized, and the power generation power is improved, and the mechanical loss and cost are reduced without the need to additionally increase equipment.

[0037] Preferably, as Figure 1 , Figure 3 and Figure 5 shown, in the embodiment, the support mechanism 202 may include a plurality of first support rollers 204, the distance between two adjacent first support rollers 204 is a first gap, the bearing mechanism 102 may include a mechanism main body 110 and a plurality of second support rollers 103 arranged on the mechanism main body 110, the distance between the plurality of second support rollers 103 is a second gap, one second support roller 103 can be arranged in one first gap, and one first support roller 204 can be arranged in one second gap. The plurality of first support rollers 204 are not limited to Figure 3 the four support rollers given therein, and may also include two, three or more, as long as the heavy object body 203 can be transported from the transportation channel 201 to the support mechanism 202. The method of transporting from the transportation channel 201 to the support mechanism 202 is not limited either. For example, all support rollers can be laid on the transportation channel 201, and the distance between these support rollers is the first gap, or it can be, for example, hoisted onto the plurality of first support rollers 204 by a car-like mechanism or a top gantry-like mechanism. The bearing mechanism 102 can be, for example, a fork similar to that of a forklift (as Figure 5 shown), including a mechanism main body 110 and a plurality of second support rollers 103 arranged on the mechanism main body 110. The second support rollers 103 can be the "forks" of the fork, which play a role in supporting the heavy object body 203. The mechanism main body 110 is located on the side of the first support rollers 204 during actual use and does not interfere with the first support rollers 204, playing a role in supporting and positioning the first support rollers 204. Only the second support rollers 103 and the first support rollers 204 perform the coupling and decoupling movements. In this way, through the cooperation of the bearing mechanism 102 similar to the fork structure and the plurality of first support rollers 204 arranged at intervals from each other, the loading and unloading of the heavy object body 203 can be realized.

[0038] Preferably, as Figure 1 and Figure 2As shown, in the embodiment, the runner member includes a first runner 106 and a second runner 107, and the first runner 106 and the second runner 107 are respectively disposed at both ends of the transportation module 1. The first runner 106 and the second runner 107 can respectively limit both ends of the chain condition 101.

[0039] Preferably, as Figure 1 and Figure 2 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. On both sides of the first runner 106 in the first direction are the first area 205 and the second area 206 respectively, and on both sides of the second runner 107 in the first direction are the third area 207 and the fourth area 208 respectively. Here, the first direction can be understood as the direction from left to right in Figure 1 and Figure 2 . The first area 205 and the third area 207 are arranged crosswise with the second area 206 and the fourth area 208.

[0040] Preferably, as Figure 1 and Figure 2 shown, in the embodiment, during the power generation process of the gravity energy storage device with the function of continuously loading and unloading heavy objects, the carrying mechanism 102 loads the heavy object body 203 in the first area 205 and the second area 206, and the carrying mechanism 102 unloads the heavy object body 203 in the third area 207 and the fourth area 208; the carrying mechanism 102 can drive the heavy object body 203 located in the first area 205 to move to the third area 207 or the carrying mechanism 102 can drive the heavy object body 203 located in the second area 206 to move to the fourth area 208. Due to the movement influence of the chain condition 101, in order to achieve the continuous loading and unloading of the heavy object body 203, it is necessary to transport the heavy object body 203 to the corresponding cross position. Here, the cross position can be understood as in Figure 2 , in the vertical projection of, the first area 205 and the third area 207 are the cross positions.

[0041] Preferably, as Figure 1 and Figure 2As shown, in the embodiment, the transportation module 1 may further include a commutator 104 and a generator 105. The generator 105 is connected to the runner member through the commutator 104, and the runner member changes its rotation direction under the drive of the commutator 104. In actual use, the gravity energy storage device with the function of continuous operation during heavy object loading and unloading may have two moving parts. That is, by changing the movement direction of the chain condition 101, when generating electricity, the heavy object body 203 in the first area 205 can move to the third area 207, or the heavy object body 203 in the second area 206 can move to the fourth area 208. Thus, the user can schedule in different areas according to needs. For example, if the number of heavy object bodies 203 in the first area 205 is large, the chain condition 101 can be rotated clockwise for a long time; if the number of heavy object bodies 203 in the second area 206 is large, the chain condition 101 can be rotated counterclockwise for a long time, so as to meet the needs of power generation and scheduling.

[0042] Preferably, as Figure 1 shown, in the embodiment, the runner member includes a first transmission part 108 and a second transmission part 109. In the vertical projection, the runner member can be formed as a circular member. 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 semi-circular members, and the first transmission part 108 is located above the second transmission part 109. The transportation channel 201 can be arranged at the connection of the first transmission part 108 and the second transmission part 109. Such a setting can enable the heavy object body 203 to dock with the bearing mechanism 102 at the outermost side of the runner member formed as a circular member. In other words, the heavy object body 203 needs to dock with the bearing mechanism 102 within the effective length of the chain condition 101. Here, the effective length can be understood as the part where the chain condition 101 moves in the vertical direction. If the number of transportation channels 201 is multiple, the highest position of the multiple transportation channels 201 in the vertical direction is also the connection of the first transmission part 108 and the second transmission part 109, and the remaining transportation channels 201 are arranged in sequence downward along the vertical direction.

[0043] Preferably, as Figure 1 shown, in the embodiment, the first area 205, the second area 206, the third area 207 and the fourth area 208 all include multiple transportation channels 201. The arrangement of multiple transportation channels 201 in the four areas respectively can transport multiple heavy object bodies 203 simultaneously to achieve high-power power generation.

[0044] Preferably, in the embodiment, in order to ensure the normal operation of the gravity energy storage device with the function of loading and unloading heavy object blocks without stopping operation, it is necessary to calculate the number of heavy object blocks 203 that can be carried simultaneously according to each structure of the gravity energy storage device with the function of loading and unloading heavy object blocks without stopping operation. Specifically, the vertical effective length of the chain condition 101 is set as L. For the convenience of understanding, the numerical effective length can be understood as the distance between the transport channel 201 at the top and the transport channel 201 at the bottom in Figure 1 . The running linear speed of the chain condition 101 is V, the loading time of each heavy object block 203 is T, and the number of heavy object blocks 203 that the gravity energy storage device with the function of loading and unloading heavy object blocks without stopping operation can carry simultaneously is N, then N = L / V / T.

[0045] Preferably, in the embodiment, the mass of each heavy object block 203 is set as m, and the output power of the gravity energy storage device with the function of loading and unloading heavy object blocks without stopping operation is P, then P = N × m × g × V, where g is the acceleration due to gravity. If the gravity energy storage device with the function of loading and unloading heavy object blocks without stopping operation 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 a region, and the four regions correspond, for example, to Figure 1 the two transport channels 201 in the first region 205 in

[0046] One operation process of the gravity energy storage device with the function of loading and unloading heavy object blocks without stopping operation is as follows: Taking the power generation process in which the heavy object block 203 in Figure 4 moves from the first region 205 to the third region 207 as an example, after the heavy object block 203 is transported through the transport channel 201 and reaches the coupling position in the first region 205, the chain condition 101 directly drives the heavy object block 203 into the transport module 1, and no other actuators are required during the process of loading the heavy object block 203. After the heavy object block 203 passes through the rotating member, it drives the chain condition 101 to move at a constant speed under its own gravity, thereby driving the generator 105 to generate electricity. The constant speed movement can be understood as follows: After the first heavy object block 203 moves from the first region 205 to the third region 207, at this time, the power generation process has already started, and the chain condition 101 is driven. Since the weight of each heavy object block 203 is the same, the movement of the chain condition 101 also gradually approaches a constant speed. In addition, the constant speed rotation can also be artificially regulated by the controller, for example, by driving the speed governor by the controller, so as to shorten the period of approaching the constant speed rotation. After the heavy object block 203 reaches the coupling position in the third region 207, no other actuators are required, and the heavy object block 203 can enter the transport channel 201, and the chain condition 101 does not need to pause, and the running speed remains unchanged, and then the next cycle continues.

[0047] The gravity energy storage device with the function of loading and unloading heavy object blocks without stopping the operation can load and unload the heavy object block body without stopping the operation of the device during the power generation and energy storage processes through the cooperation of the transportation module and the loading and unloading module. At the same time, since the runner parts and the chain conditions can always be in a moving state, the transportation module can generate stable and continuous electric energy during power generation, so as to realize that the power generation system always generates 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 block body can be realized, and additional loading and unloading devices can be omitted. Without the need to additionally increase equipment, the power generation power is improved, the operation efficiency is improved, and the mechanical loss and cost are reduced.

[0048] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting it. The protection scope of the present application is not limited thereto.
