Description

Technical Field

[0001] The present application relates to the technical field of gravity energy storage, and in particular to a circulation device for continuous and stable power generation for gravity energy storage. 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] There are several problems with existing gravity energy storage devices: First, the existing gravity energy storage power generation scheme cannot achieve single-channel circulation. The front-end mechanical input device connected to the generator starts and stops 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 there is only one heavy block driving 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 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 heavy blocks is limited to the order of m / s in the single digit, 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 high-power generators to generate electricity, but 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 gravity energy storage schemes, the load-bearing device of the heavy block corresponds to the heavy block one by one, and the flexible scheduling of the heavy block cannot be achieved, the equipment utilization rate is low, and the load-bearing device circulation efficiency is low.

[0004] In summary, the current gravity energy storage devices have the problems of being unable to generate electricity continuously and stably, low power generation capacity of single-channel gravity energy storage and difficulty in increasing power generation capacity, large mechanical losses, high costs, inability to achieve flexible scheduling of heavy blocks, low equipment utilization rate and low circulation efficiency of the carrying device.

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.

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 circulation device for continuous and stable power generation of gravity energy storage is provided, such as Figures 1 to 3 As shown, the circulation device for continuous and stable power generation for gravity energy storage is used for gravity energy storage, and can realize single-channel continuous and stable power generation. The circulation device for continuous and stable power generation for gravity energy storage includes a weight block body 1, a bearing mechanism 2, a weight circulation module 3 and a bearing circulation module 4.

[0027] In the following description, reference will be made to Figures 1 to 3 The detailed structures of the weight block body 1, the bearing mechanism 2, the weight circulation module 3 and the bearing circulation module 4 of the circulation device for continuous and stable power generation using gravity energy storage are specifically described.

[0028] like Figure 1 As shown, in the embodiment, the bearing mechanism 2 can load the weight block body 1. Specifically, in the embodiment, the weight block body 1 can be a common rectangular parallelepiped structure block, which has a regular structure and is convenient for storage, transportation and use. However, it is not limited to this, and the weight block body 1 can also be spherical, cubic or other shapes according to different usage scenarios, which is not limited here.

[0029] The load-bearing mechanism 2 can be, for example, a car-type mechanism, a top gantry-type mechanism, or a bottom tray-type mechanism in the prior art. Accordingly, the loading method can be, for example, a commonly used loading method in the prior art, such as loading in the car, loading on the top gantry, or loading on the bottom tray. However, it is not limited thereto. The load-bearing mechanism 2 can be used to carry and transport the heavy object block body 1. The loading method and specific structure are not limited thereto, and those skilled in the art can know it.

[0030] The heavy object circulation module 3 may include a rotating wheel 302 and a chain condition 301 arranged along a conveying direction, where the conveying direction may be, for example, Figures 1 to 3 The chain link 301 rotates around the rotating wheel 302, and the way of rotating can be, for example: Figure 2 As shown, at both ends of the heavy object circulation module 3 in the vertical direction, there are rotating wheels 302, and a chain 301 surrounds the two rotating wheels 302. When the chain 301 moves, it can drive the rotating wheels 302 to rotate, and the rotating wheels 302 can play a role of limiting. Figure 2 The left and right ends of the chain 301 can be connected to a chain condition 301 respectively, that is, can be engaged with the chain condition 301 to ensure stability during movement.

[0031] Further, the carrying mechanism 2 is slidably disposed on the heavy object circulation module 3 along the conveying direction. In the embodiment, the carrying mechanism 2 can be slidably disposed on the heavy object circulation module 3 by the following sliding mechanism (not shown). It can be understood that the sliding mechanism can play the role of limiting and connecting, and the carrying mechanism 2 is driven to slide along the sliding mechanism through the influence of the gravity of the heavy object block body 1.

[0032] Furthermore, the chain condition 301 can keep moving. The keeping moving here means that when the circulation device for continuous and stable power generation for gravity energy storage is in working state, the chain condition 301 is always in a rotating state. The rotation of the chain condition 301 can be driven by the first weight block body 1 and the first bearing mechanism 2. That is, when the circulation device for continuous and stable power generation for gravity energy storage is started, the chain condition 301 is not affected by external force and is in a static state. After the first weight block body 1 is loaded onto the first bearing mechanism 2 (the first one here can be understood as Figure 1 The weight block body 1 and the carrying mechanism 2 at the top position in the embodiment of the present invention are shown in FIG. 1 . As the first weight block body 1 is affected by gravity, it will drive the first carrying mechanism 2 and the chain condition 301 engaged with the first carrying mechanism 2 to move Figure 1The downward movement in the gravity energy storage device for continuous and stable power generation is already in the power generation state, and the chain condition 301 can always be in the rotating state. Furthermore, in order to ensure the stability of the movement, the speed of the wheel 302 can be adjusted by selecting and using components such as speed detectors and speed controllers, so that the rotation of the chain condition 301 is in a uniform speed state. In this way, since each chain condition 301 can achieve stable reciprocating operation, the entire channel has a single-channel circulation capability, and self-circulation can be achieved without the help of any other channels or facilities.

[0033] When the circulation device for continuous and stable power generation using gravity energy storage is in the working state of power generation, there is an accumulation-release behavior between the supporting mechanism 2 and the chain condition 301. Specifically, when the supporting mechanism 2 is not loaded with the weight block body 1, the end of the supporting mechanism 2 moves relative to the chain condition 301, and the position of the supporting mechanism 2 does not change, that is, "accumulation". At this time, the chain condition 301 will rotate at a constant speed driven by the preceding weight block body 1, while the supporting mechanism 2 that is not loaded with the weight block body 1 remains stationary. In addition, the relative movement here can be understood as the chain condition 301 being in a state of rotation around the rotating wheel 302, while the supporting mechanism 2 that is not loaded with the weight block body 1 remains stationary, waiting to be loaded with the weight block body 1. Figure 3 As shown, when the load-bearing mechanism 2 is loaded with the weight block body 1, the end of the load-bearing mechanism 2 is relatively stationary with the chain condition 301, and the load-bearing mechanism 2 moves following the chain condition 301 and moves the weight block body 1 from the loading position 304 to the unloading position 305 (the loading position 304 and the unloading position 305 can be understood as Figure 1 The upper and lower ends of the heavy object circulation module 3). The bearing mechanism 2 will keep the synchronous movement with the chain condition 301, that is, "release". In addition, the relative stillness here can be understood as the end of the bearing mechanism 2 is engaged with the chain condition 301 at this time, and the end of the bearing mechanism 2 can move together with the chain condition 301, so that the heavy object block body 1 moves from the loading position 304 to the unloading position 305, completing the power generation process of gravity energy storage. In this way, it can be understood that since the chain condition 301 is always in motion, the fluctuation effect of the heavy object block body 1 on the power output power during loading and unloading can be fundamentally eliminated.

[0034] like Figure 1 and Figure 3 As shown, after unloading the weight block body 1, the carrying mechanism 2 is returned to the loading position 304 by the carrying circulation module 4. Figure 1 As shown, the weight block body 1 moves from the loading position 304 to the unloading position 305, and then the weight block body 1 performs a cyclic motion along the following transverse channel 308, and the direction of the cyclic motion is as follows: Figure 1As shown by the arrow on the left side of the figure. When generating electricity, the bearing mechanism 2 carries the weight block body 1, and drives the chain condition 301 to rotate at a uniform speed to drive the following generator 307 to generate electricity. Since there is a cumulative release behavior between the bearing mechanism 2 and the chain condition 301, during the "release" process, the movement of the chain condition 301 will be disturbed or impacted, and the impact is directly related to the linear speed of the chain condition 301 running along the conveying direction, so the linear speed of the chain condition 301 will not be very large. Then, after the bearing mechanism 2 unloads the weight block body 1, it needs to return to continue to connect the next weight block. In this process, if the linear speed of the chain condition 301 is still used, the return speed of the bearing mechanism 2 will be slow, the flexibility is poor, and the waiting time is long. The additionally set bearing circulation module 4 can make the return route of the bearing mechanism 2 independent, and its return speed can be controlled separately, which can effectively ensure the operation efficiency of the weight block and the power generation efficiency of the overall equipment, and because the return speed can be controlled separately, the bearing mechanism 2 is flexible to dispatch and can be dispatched on demand.

[0035] The circulation device for continuous and stable power generation using gravity energy storage can achieve that the chain condition 301 is always in a rotating operation state during the power generation process through the cooperation of the heavy object block body 1, the supporting mechanism 2, the heavy object circulation module 3 and the supporting circulation module 4, thereby making the power generation stable and continuous. Since the chain condition 301 in the heavy object circulation module 3 can cooperate with the supporting mechanism 2 in an accumulation-release manner, a single-channel gravity energy storage power generation cycle can be achieved, and there is no need to install additional auxiliary equipment to ensure large power generation and continuous and stable power generation, thereby reducing mechanical losses. Since the supporting mechanism 2 can circulate independently in the supporting circulation module 4, the supporting mechanism 2 and the heavy object block body 1 can also be flexibly dispatched, thereby reducing the idle rate of the supporting mechanism 2 and improving the equipment utilization rate and the circulation efficiency of the supporting mechanism 2.

[0036] Preferably, if Figures 1 to 3 As shown, in the embodiment, the heavy object circulation module 3 may include a module body, and the module body is provided with a first circulation channel 303. The module body may be understood as the main device of the heavy object circulation module 3, and may be, for example, a building body made of reinforced concrete, and the first circulation channel 303 is opened inside the building body. The two ends of the first circulation channel 303 are respectively a loading position 304 and an unloading position 305, and the direction extending from the loading position 304 toward the unloading position 305 or the direction extending from the unloading position 305 toward the loading position 304 is the conveying direction.

[0037] Preferably, if Figure 2As shown, in the embodiment, both the loading position 304 and the unloading position 305 are provided with a rotating wheel 302, and the end of the carrying mechanism 2 that meshes with the chain condition 301 is provided with a gear assembly 202 and a brake assembly (not shown), the gear assembly 202 is rotatably arranged at the end of the carrying mechanism 2, the gear assembly 202 can mesh with the chain condition 301, and the brake assembly can stop the gear assembly 202 from rotating. The chain condition 301 can be a common chain structure, for example, composed of a plurality of chain links, each of which has a clamping hole in the middle, and the gear assembly 202 can be, for example, composed of one or more gears, one of which can mesh with the clamping hole, so as to achieve the meshing of the end of the carrying mechanism 2 with the chain condition 301. Furthermore, the specific structure of the accumulation and release connection can be, for example, as follows: while the bearing mechanism 2 is waiting for the weight block body 1 to be loaded or unloaded, the gear assembly 202 of the bearing mechanism 2 is meshed with the chain condition 301. At this time, since the chain condition 301 is in a state of uniform rotation driven by the previous weight block body 1, the meshed gear assembly 202 will be driven to rotate, but the position of the bearing mechanism 2 has not changed, that is, the bearing mechanism 2 is stationary in the conveying direction ("accumulation"). After the action of loading or unloading the weight block body 1 is completed, the gear assembly 202 is affected by the brake assembly and is locked. At this time, the gear assembly 202 is still in meshing with the chain condition 301. Then, when the chain condition 301 rotates at a uniform speed, it will drive the bearing mechanism 2 to maintain synchronous speed movement ("release"), thereby adding the weight block body 1 to the power generation array. This method ensures that the weight block body 1 does not stop during the loading and unloading process, thereby ensuring that the generator 307 is always in a uniform rotation state. In addition, the gear assembly 202 and the brake assembly can both be components in the prior art, and their structures can be, for example, the brake and wheel hub structure of a vehicle. The brake assembly can be driven by an external sensor to lock the gear assembly 202.

[0038] Preferably, in the embodiment, a sliding assembly (not shown) is provided on the inner side wall of the first circulation channel 303, and the supporting mechanism 2 is slidably connected to the first circulation channel 303 through the sliding assembly. The sliding assembly can be, for example, a rope or a slider rail, the rope is connected to the rope by providing a connection position on the side wall of the supporting mechanism 2, and the limited sliding of the supporting mechanism 2 is achieved by retracting and releasing the rope, and the slider rail is provided with a vertical slide rail in the first circulation channel 303, and a slider is provided on the supporting mechanism 2, and the limited sliding is achieved by connecting the slider rail.

[0039] Preferably, if Figures 1 to 3 As shown, in the embodiment, in order to improve the circulation efficiency, the number of the supporting mechanisms 2 is multiple, and the multiple supporting mechanisms 2 are sequentially arranged at intervals in the heavy object circulation module 3. Accordingly, the more the number of the supporting mechanisms 2 is, the higher the power generation efficiency in one first circulation channel 303 is.

[0040] Preferably, if Figures 1 to 3 As shown, in the embodiment, in order to further ensure the stability of power generation, the heavy object circulation module 3 may include a plurality of chain links 301 , and at least two ends of the supporting mechanism 2 are connected to the chain links 301 .

[0041] Preferably, if Figures 1 to 3 As shown, in the embodiment, the runner 302 located at the end of the chain condition 301 is connected to the generator 307 through the bevel gear shaft 306. Since the number of chain conditions 301 is multiple, and for example Figure 2 The left and right chain elements 301 rotate in different directions, so an additional bevel gear shaft 306 is required to connect them, and the bevel gear shaft 306 is connected to the generator 307 to ensure stable and continuous power generation.

[0042] Preferably, if Figure 1 As shown, in the embodiment, the carrying circulation module 4 may include a second circulation channel 401, the second circulation channel 401 is connected to the first circulation channel 303, and the movement direction of the carrying mechanism 2 in the second circulation channel 401 is opposite to the movement direction in the first circulation channel 303. The carrying mechanism 2 can return to the first circulation channel 303 via the second circulation channel 401. The specific structure of the second circulation channel 401 can be a common conveying channel of a gravity energy storage device, and its structure has no special requirements and special restrictions, as long as it can enable the carrying mechanism 2 to return.

[0043] Preferably, if Figures 1 to 3 As shown, in the embodiment, the bearing mechanism 2 may include a hoisting mechanism 201, and the hoisting mechanism 201 is connected to the weight block body 1. The weight block body 1 is installed on the bearing mechanism 2 by hoisting, and the hoisting mechanism 201 may be, for example, a top gantry-type mechanism commonly used in the prior art, which will not be described in detail here.

[0044] Preferably, if Figure 1 and Figure 3As shown, in an embodiment, the weight block body 1 is loaded on the hoisting mechanism 201 via a transverse channel 308, and the number of transverse channels 308 is multiple, and multiple transverse channels 308 are arranged in sequence and at intervals along the conveying direction. The provision of multiple transverse channels 308 allows the weight circulation module 3 to load multiple weight block bodies 1 at the same time, thereby increasing the power generation. If the weight circulation module 3 includes a transverse channel 308, then the power generation of this weight circulation module 3 is doubled, and if it includes three transverse channels 308, then the power generation of this weight circulation module 3 is tripled, and if it includes multiple transverse channels 308, then the power generation of this weight circulation module 3 is multiple times. When multiple transverse channels 308 are provided, it is only necessary to ensure that the loading position 304 and the unloading position 305 have a sufficient height difference. The transverse channel 308 can be, for example, a common conveying channel in gravity energy storage, such as a long strip channel composed of multiple conveying rollers.

[0045] Preferably, in the embodiment, in order to ensure that the circulation device for continuous and stable power generation for gravity energy storage can operate normally, it is necessary to calculate the number of weight block bodies 1 that can be carried at the same time according to the various structures of the circulation device for continuous and stable power generation for gravity energy storage. Specifically, the vertical effective length of the chain condition 301 is set to L, and the numerical effective length can be understood as Figure 1 The distance between the transverse channel 308 at the top and the transverse channel 308 at the bottom. The running linear speed of the chain condition 301 is V, the loading time of each weight block body 1 is T, and the number of weight block bodies 1 that can be carried simultaneously by the circulation device for continuous and stable power generation for gravity energy storage is N, then N=L / V / T. Further, the mass of each weight block body 1 is set to m, and the output power of a circulation device for continuous and stable power generation for gravity energy storage is P, P=N×m×g×V, g is the acceleration of gravity. If the circulation device for continuous and stable power generation for gravity energy storage includes the above-mentioned multiple transverse channels 308, then the output power P=N×m×g×V×the number of transverse channels 308.

[0046] The operation process of the continuous and stable power generation circulation device for gravity energy storage is as follows: start the device. When starting, the device is in a state of overall stillness. At this time, the chain condition 301 is still. The first weight block body 1 is transported to the first bearing mechanism 2 which is still at this time through the transverse channel 308. The bearing mechanism 2 is meshed with the chain condition 301 through the gear assembly 202. The gear assembly 202 is kept still by the brake assembly. Due to the influence of the gravity of the weight block body 1, the weight block body 1, the bearing mechanism 2 and the chain condition 301 move together, thereby making the chain The chain 301 starts to rotate and gradually approaches uniform rotation (uniform rotation can also be artificially controlled by the controller to shorten the period of approaching uniform rotation). After the first weight block body 1 is transported, the second weight block body 1 is transported to the loading position 304 via the transverse channel 308. At this time, the gear assembly 202 of the second bearing mechanism 2 is not affected by the brake assembly. The gear assembly 202 and the chain 301 rotate at the same speed. The bearing mechanism 2 remains stationary in the first circulation channel 303, waiting for the loading of the second weight block body 1. Since the chain 301 is always in a state of rotation and approaching uniform rotation, the bevel gear shaft 306 driven by the chain 301 rotates and drives the generator 307 to generate electricity. The generator 307 can generate electricity stably and continuously. In addition, since in the first circulation channel 303, the overall circulation does not require the additional installation of other mechanical equipment, so the mechanical loss is greatly reduced and the cost is reduced. Afterwards, after the first carrying mechanism 2 and the second carrying mechanism 2 are transported to the unloading position 305, they return to the loading position 304 of the first circulation channel 303 via the second circulation channel 401. Since the carrying mechanism 2 can quickly return to the first circulation channel 303 via the second circulation channel 401, the utilization rate of the carrying mechanism 2 can be improved, and the circulation efficiency of the overall device can be further improved.

[0047] The circulation device for continuous and stable power generation using gravity energy storage can achieve that the chain condition is always in a rotating operation state during the power generation process through the cooperation of the weight block body, the carrying mechanism, the weight circulation module and the carrying circulation module, thereby making the power generation stable and continuous. Since the chain condition can cooperate with the carrying mechanism in an accumulation-release manner in the weight circulation module, a single-channel gravity energy storage power generation cycle can be achieved, and the power generation power can be large and continuous and stable without installing additional auxiliary equipment, thereby reducing mechanical losses. Since the carrying mechanism can circulate independently in the carrying circulation module, the carrying mechanism and the weight block body can be flexibly dispatched, thereby reducing the no-load rate of the carrying mechanism and improving the equipment utilization rate and the circulation efficiency of the carrying mechanism.
