Description

Technical Field

[0001] This utility model relates to the field of gravity energy storage, specifically to a gravity energy storage storage yard. Background Technology

[0002] In the global wave of energy structure transformation towards cleaner and lower-carbon energy, the rapid development of renewable energy is leading a profound energy revolution. However, renewable energy sources such as wind and solar power are characterized by significant intermittency and volatility, and their power generation is closely related to natural conditions, making it difficult to perfectly match grid load demand. This characteristic poses a severe challenge to the stable operation of the power system, making energy storage technology a key solution for balancing supply and demand and enhancing grid resilience. With the increasing global demand for clean energy and energy security, and the pressure of resource constraints (such as shortages of rare metals like lithium and cobalt) and rising costs facing traditional battery energy storage technology, gravity energy storage has become a prominent emerging force in the energy storage field due to its unique advantages of being environmentally friendly and having a long lifespan.

[0003] As a novel distributed gravity energy storage system, the design of the energy storage yard is a crucial component of the track-mounted gravity energy storage system. The current challenge is to achieve a rational layout of the yard tracks, energy storage medium, and grabbing components to enable rapid loading and unloading, thereby improving the continuous, efficient, and stable operation of the entire gravity energy storage cycle system. Utility Model Content

[0004] This invention provides a gravity energy storage reactor to solve the technical problems mentioned in the background art.

[0005] This utility model provides a gravity energy storage yard, including at least one yard unit. Each yard unit includes a yard frame, energy storage blocks stacked within the yard frame, and a hoisting device positioned above the yard frame. The energy storage blocks are stacked in multiple rows to form a storage block area. The yard frame is also equipped with a loading / unloading track for stopping transport trains to load / unload the energy storage blocks. The length of the loading / unloading track is greater than or equal to the length of the transport train. The hoisting device is equipped with multiple gripping parts, which are spaced apart along an extension direction. The extension direction of the gripping parts and each row of energy storage blocks in the storage block area is parallel to the loading / unloading track. The gripping parts move back and forth between the loading / unloading track and the storage block area in a direction perpendicular to the loading / unloading track.

[0006] Furthermore, the loading and unloading tracks are arranged in straight sections.

[0007] Furthermore, each gripping unit can only grip one energy storage block at a time, and along the gripping translation direction of the gripping unit, each gripping unit and the corresponding energy storage block to be gripped are set on the same vertical plane.

[0008] Furthermore, when the transport train stops at the loading and unloading track, along the direction perpendicular to the loading and unloading track, the transport train carriage, the corresponding energy storage weight, and the gripping part of the corresponding energy storage weight are on the same vertical plane.

[0009] Furthermore, the hoisting device includes one or more hoisting components, each hoisting component is integrated with at least one gripping part, the hoisting component includes a lateral lifting mechanism, each gripping part is connected to the lateral lifting mechanism on the corresponding hoisting component, the lateral lifting mechanism can drive the gripping part to rise and fall in the vertical direction and to move laterally perpendicular to the loading and unloading track direction.

[0010] Furthermore, one or both ends of the loading and unloading track are connected to a transport track.

[0011] Furthermore, the stockyard unit is provided in multiple sets, and when the transport tracks corresponding to the loading and unloading tracks of the multiple sets of stockyard units are connected, a switch is used for connection.

[0012] Furthermore, when the transport train stops at the loading and unloading track, multiple gripping parts on the hoisting device corresponding to the carriages of the transport train are simultaneously loaded or unloaded in one go.

[0013] The beneficial effects of this utility model are as follows: By arranging the loading and unloading tracks, the energy storage blocks in the stockpile area, and the position and direction of the gripper in the stockpile unit, this utility model not only satisfies the need for a compact spatial layout of the stockpile unit, but also achieves the shortest path for the gripper to the energy storage blocks and the loading and unloading tracks for back-and-forth loading and unloading, thereby improving the loading and unloading efficiency of the stockpile unit.

[0014] In addition, when the transport train stops at the loading and unloading track, multiple gripping parts corresponding to the transport train carriages can be controlled to simultaneously load or unload in one go along the direction perpendicular to the loading and unloading track. This achieves one-time rapid loading and unloading of multiple carriages along the shortest path, solving the core pain point of existing gravity energy storage yards being slow in loading and unloading, unable to meet the continuous operation requirements of circular transportation, and having low efficiency.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Combination Figure 1 The gravity energy storage yard shown includes a set of yard units. Each yard unit includes a yard frame 11, energy storage weights 12 arranged and stacked within the yard frame 11, and a hoisting device 13 installed on the yard frame 11.

[0019] The energy storage weights 12 are arranged in multiple rows and columns to form a stacking area located below the stacking rack 11. The energy storage weights 12 are configured as a type of counterweight. The power generation of the energy storage system can be adjusted by the number of them loaded onto the transport train 2. In this embodiment, the energy storage weights 12 can be prefabricated into standard blocks, such as reinforced concrete blocks, metal blocks, or filling blocks, etc. The shape can be set as rectangular and placed in the stacking area. The energy storage weights 12 can be arranged in a single layer or stacked to form rows.

[0020] In this embodiment, the transport train 2 includes multiple carriages 21, which are flexibly connected. Each carriage 21 is configured to carry energy storage blocks 12. Its structural form can be set according to the form of the energy storage blocks 12, such as a flatbed or a box-type. The number of energy storage blocks 12 loaded in the carriage 21 can also be adjusted between empty and full load according to the needs of the energy storage system. The loading and unloading of the energy storage blocks 12 is realized through a gravity energy storage yard.

[0021] The storage rack 11 is also equipped with a loading and unloading track 3 for parking the transport train 2 to load / unload the energy storage heavy blocks 12. The length of the loading and unloading track 3 is greater than or equal to the length of the transport train 2. The unloading track 3 is arranged close to the storage block area. The hoisting device 13 is equipped with multiple gripping parts 131. The multiple gripping parts 131 are spaced apart along an extension direction. The extension direction of the gripping parts 131 and each row of energy storage heavy blocks 12 in the storage block area is parallel to the loading and unloading track 3. The gripping parts 131 move back and forth between the loading and unloading track 3 and the storage block area in a direction perpendicular to the loading and unloading track 3.

[0022] Each gripping part 131 can only grip one energy storage block 12 at a time. Along the gripping translation direction of the gripping part 133, each gripping part 131 and the corresponding energy storage block 12 to be gripped in the stacking area are set on the same vertical plane. When the transport train 2 transports and stops at the loading and unloading track 3 on the straight section, along the direction perpendicular to the loading and unloading track 3, the transport train 2 carriage 21, the corresponding energy storage block 12 of the carriage 21, and the gripping part 131 of the corresponding energy storage block 12 are on the same vertical plane. This satisfies the requirement that along the extension direction of the loading and unloading track 3, the loading and unloading track, gripping part, and energy storage block 12 are arranged in parallel and corresponding rows, and along the direction perpendicular to the loading and unloading track 3, the transport train 2 carriage 21, the energy storage block 12 in the stacking area, and the gripping part 131 are arranged in a one-to-one correspondence.

[0023] In this embodiment, by setting the extension direction of the gripping part 131 and each row of energy storage weights 12 in the stacking area parallel to the loading and unloading track 3, the gripping part 131, the energy storage weights 12 are arranged in a row corresponding to the extension direction of the loading and unloading track 3. When the transport train 2 stops at the loading and unloading track 3, the multiple carriages 21 of the transport train 2 correspond to the arrangement direction of the gripping part 131 and the energy storage weights 12, which can realize that multiple gripping parts 131 can grip one or more times in the same row at the same time. The gripping part 131 moves back and forth between the loading and unloading track 3 and the stacking area along the direction perpendicular to the loading and unloading track, realizing the shortest path of the gripping part 131 to the energy storage weights 12 and the loading and unloading track 3 for back and forth loading and unloading, thereby improving the loading and unloading efficiency of the yard unit.

[0024] One embodiment, such as Figure 2As shown, the gravity energy storage yard includes two sets of yard units. The two sets of yard units arranged in an arrangement form a gravity energy storage yard. Two loading and unloading tracks 3 are arranged close to each other in the middle of the gravity energy storage yard. On both sides are the corresponding yard unit's block areas. Each loading and unloading track 3 is connected to a corresponding transport track 4. When the transport tracks 4 corresponding to the loading and unloading tracks 3 of the two sets of yard units are connected, they are connected by a switch and connected to the main rail. In this embodiment, the arranged energy storage blocks are placed on the support plate 5. Multiple parking tracks 6 for transport trains 2 to stop are arranged below the support plate 5. In practical applications, the energy storage blocks 12 can also be directly laid on a flat ground, and no parking tracks 6 are set under the yard frame 11.

[0025] In one embodiment, the loading and unloading track 3 is arranged in a straight section, that is, the transport train can stop horizontally and in a straight line when it stops at this section. The transport train 2 is in a straight line on the loading and unloading track 3 in the straight section. The sway displacement between each carriage 21 is guided and calibrated by the straight section, which facilitates the centralized and precise loading and unloading of the hoisting device 13. This can greatly improve the efficiency of loading and unloading, thereby improving the overall operating efficiency of the energy storage system.

[0026] The hoisting device 13 includes one or more hoisting components 132, which can be arranged in multiple ways, such as... Figure 1-4 As shown, the hoisting device 13 is equipped with multiple hoisting components 132 (each hoisting component 132 may be equipped with one or more gripping parts 131). In this way, multiple hoisting components 132 can move in unison to hoist multiple energy storage weights 12 at the same time, thereby improving loading and unloading efficiency.

[0027] Another arrangement, such as Figure 4 As shown, the hoisting assembly 132 is provided with multiple gripping parts 131, which are spaced apart along an extending direction parallel to the extending direction of the loading and unloading track 3. With this arrangement, by providing multiple gripping parts 131 to a single hoisting device 13, one hoisting assembly 132 can grab the energy storage weights 12 on multiple carriages 21 of the transport train 2, further improving loading and unloading efficiency.

[0028] like Figure 1 In order to reduce the energy consumption of the lifting device 13, each of the lifting devices 13 can be equipped with a counterweight component 7, either individually or in combination with multiple lifting components 132, which balances the weight of the gripping part 131 and the lifting block, reduces the lifting energy consumption of the drive motor, and improves the energy conversion efficiency of the system operation.

[0029] In one embodiment, during the hoisting of the energy storage block 12, a hoisting device 13 is provided on the stack area. Multiple gripping parts 131 of the hoisting device 13 are spaced apart along an extension direction, and the extension direction of the gripping parts 131 is parallel to the loading and unloading track 3. The gripping parts 131 move back and forth between the loading and unloading track 3 and the stack area along a direction perpendicular to the loading and unloading track 3. The hoisting device 13 is electrically connected to the main controller. When the transport train 2 stops at the loading and unloading track 3 on the straight section, the main controller controls the multiple gripping parts 131 on the hoisting device 13 corresponding to the carriage 21 of the transport train 2 to perform synchronous one-time loading or unloading. The entire train is hoisted in a concentrated manner, which can greatly improve the loading and unloading speed of the energy storage block 12 and improve the overall system operating efficiency.

[0030] The hoisting assembly 132 includes a lateral lifting mechanism 133. Each gripping part 131 is connected to the lateral lifting mechanism 133 on the corresponding hoisting assembly 132. The lateral lifting mechanism 133 can drive the gripping part 131 to move vertically and horizontally perpendicular to the loading and unloading track. In this embodiment, the lateral lifting mechanism 133 includes a lateral trolley mounted on the corresponding yard rack 11 of the hoisting assembly 132 and a lifting mechanism mounted on the lateral trolley. The lateral trolley can be implemented in various mechanical forms such as a sliding rail linear module or a synchronous belt linear module. The lifting mechanism can be a lifting method composed of a wire rope, a traction wheel, and a drive motor, or it can be an electric telescopic rod. Since there are many different ways to assemble the lateral trolley and the lifting mechanism on it, and these are relatively conventional mechanical combination designs, they will not be described in detail here.

[0031] like Figure 2 As shown, both ends of the loading and unloading track 3 of the storage yard unit are connected to the transport track 4. The transport train 4 enters from one end of the loading and unloading track 3, stops to complete loading and unloading, and then exits from the other end to enter the gravity energy storage transport system. In actual applications, there are also cases where the loading and unloading track 3 is only connected to the transport track 4 at one end. When the transport train 2 enters the loading and unloading track 3 of the storage yard unit and stops to complete loading and unloading, the driving mode of the transport train is controlled, and it exits along the entrance.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
