Description

Technical Field

[0001] This utility model relates to the technical field of energy storage equipment based on grid-source and load, specifically to an energy storage device based on grid-source and load. Background Technology

[0002] The power grid-source-load-storage (PGS) concept refers to the integrated and coordinated operation of the four components of a power system: power generation, grid, load, and storage. This aims to achieve efficient utilization of power resources and stable operation of the power system. The power generation component is responsible for converting various forms of energy into electrical energy. The grid is the power transmission and distribution network, responsible for delivering electricity generated by power plants to various power-consuming areas. The load component is the power consumption component; demand on the load side varies with time, weather, economic activities, and other factors, affecting the supply-demand balance of the power system. Storage refers to the equipment and technologies used in the power system to store electrical energy. Energy storage systems can store energy when demand is low and release energy when demand is high, helping to balance grid load and improve grid flexibility and reliability.

[0003] Patent CN218895158U discloses a patent entitled "An Integrated Regulation of Source-Grid-Load-Storage System for New Energy Power Stations," which includes a main body of new energy storage equipment and a supporting base. The supporting base is cylindrical, with a supporting slide column at its top. The front and rear ends of the supporting slide column have toothed grooves. A fixed slider is located in the middle of the supporting slide column, and a sliding groove is located in the middle of the fixed slider, which engages with the supporting slide column. Rotary motors are located at the front and rear ends of the fixed slider, and each rotating end of the motor has a rotating gear that meshes with the toothed groove. A U-shaped fixing block is located at the left end of the fixed slider, and the main body of the new energy storage equipment is located in the middle of the U-shaped fixing block. Fixing bolts are located at the front and rear ends of each U-shaped fixing block. This design facilitates height adjustment, making equipment maintenance easier. It eliminates the need for workers to climb to change equipment, reducing the risk of injury and enhancing practicality.

[0004] The technologies described in the aforementioned patents are convenient for height adjustment and facilitate equipment maintenance and repair. However, they have the drawback that before the main body of the new energy storage device is placed on the U-shaped fixing block for lifting and lowering, fixing bolts are needed at the front and rear ends of the U-shaped fixing block to fix the main body of the new energy storage device on the U-shaped fixing block. To ensure the fixing effect, multiple fixing bolts are required. The fixing process is slow, labor-intensive, and inefficient, and needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a source-grid-load energy storage device to address the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a source-grid-load energy storage device, comprising a storage module and a base, wherein a support seat is slidably disposed on the base in the vertical direction, the storage module is placed on the support seat, and counter-rotating clamping plates are disposed on both sides of the support seat; a driving assembly is disposed on the base for driving the support seat to move relative to the base in the vertical direction, and a transmission assembly is also provided, wherein the transmission assembly corresponds one-to-one with the clamping plates, and during the movement of the support seat, the transmission assembly drives the corresponding clamping plates to rotate.

[0007] Furthermore, the drive assembly includes a motor, a screw, and a threaded sleeve. The screw is rotatably mounted inside the base, the motor is fixedly mounted at the bottom of the base, the motor shaft is coaxially and fixedly connected to the screw, and the threaded sleeve is slidably connected to the base and rotatably connected to the screw.

[0008] Furthermore, the threaded sleeve is provided with a slider, and the base is provided with a groove adapted to the slider, and the slider slides in cooperation with the groove.

[0009] Furthermore, the transmission assembly includes a gear, a rack, and a one-way valve structure. The gear is fixedly mounted on the shaft of the corresponding clamping plate, and the rack is fixedly mounted on the base in the vertical direction. During the movement of the support seat, the gear meshes with the corresponding rack. When the support seat rises, the one-way valve structure can lock the corresponding clamping plate. When the support seat falls, the one-way valve structure can unlock the corresponding locked clamping plate.

[0010] Furthermore, the one-way valve structure includes a locking unit and an unlocking unit. The locking unit includes a pawl and a stop bar. The pawl is rotatably mounted on the support base, and an elastic element is provided between the pawl and the support base. The process of the elastic element restoring its deformation drives the pawl to abut against the stop bar. When the gear disengages from the corresponding rack, the pawl engages with the corresponding gear. When the support base descends, the unlocking unit is used to actuate the pawl to unlock the locked clamping plate.

[0011] Furthermore, the unlocking unit includes a sliding column and a guide plate. The sliding column is fixedly mounted on the pawl, and the guide plate is mounted on the housing. When the support seat descends, the sliding column can engage with the guide plate, causing the pawl to move away from the gear.

[0012] Furthermore, the elastic element is a torsion spring, one end of which is fixedly connected to the support base, and the other end of which is fixedly connected to the pawl.

[0013] Compared with the prior art, the energy storage device provided by this utility model moves the storage module placed on the support base through the drive component. During the process of the support base being raised, the transmission component drives the corresponding clamping plate to rotate to clamp and fix the storage module; during the process of the support base being lowered, the transmission component drives the corresponding clamping plate to rotate to unfold and release the storage module. The fixing and releasing processes do not require the operation of personnel, which reduces the workload and improves the work efficiency. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-8 This utility model provides a source-grid-load energy storage device, including a storage module 1 and a base 12. A support base 11 is slidably mounted on the base 12 in the vertical direction. The storage module 1 is placed on the support base 11. Two counter-rotating clamping plates 13 are provided on both sides of the support base 11. A driving assembly is provided on the base 12 to drive the support base 11 to move vertically relative to the base 12. During the lifting process of the support base 11, two transmission assemblies drive the two clamping plates 13 to rotate counter-rotate to close and fix the storage module 1. During the lowering process of the support base 11, the transmission assemblies drive the two clamping plates 13 to rotate counter-rotate to unfold and release the storage module 1.

[0027] Please see Figure 4 In this embodiment of the invention, the driving assembly includes a motor, a screw 21, and a threaded sleeve 22. The screw 21 is rotatably mounted inside the base 12, and the motor is fixedly mounted at the bottom of the base 12. The motor shaft is coaxially and fixedly connected to the screw 21. The threaded sleeve 22 is slidably connected to the base 12 and rotatably connected to the screw 21. Specifically, the threaded sleeve 22 is provided with a slider 23, and the base 12 has a groove adapted to the slider 23. The slider 23 slides in conjunction with the groove. When the motor drives the screw 21 to rotate, causing the threaded sleeve 22 on the screw 21 to move relative to the housing, the slider 23 on the threaded sleeve 22 slides in conjunction with the groove inside the housing to limit the movement of the threaded sleeve 22, causing the threaded sleeve 22 to move along the lifting direction of the storage module 1. The threaded sleeve 22 is fixedly connected to the support base 11, and the movement of the threaded sleeve 22 also drives the support base 11 to move.

[0028] The transmission assembly includes a gear 31, a rack 32, and a one-way valve structure. The gear 31 is fixedly mounted on the shaft 1301 of the corresponding clamping plate 13. The rotation of the gear 31 drives the shaft 1301 to rotate, and the rotation of the shaft 1301 causes the clamping plate 13 to flip. The rack 32 is fixedly mounted on the base 12 in the vertical direction. During the movement of the support base 11, the gear 31 meshes with the corresponding rack 32. When the support base 11 rises, the gear 31 meshes with the corresponding rack 32 to drive the clamping plate 13 to rotate and close the storage module 1. The one-way valve structure can lock the corresponding clamping plate 13. When the support base 11 falls, the one-way valve structure can unlock the corresponding locked clamping plate 13, and the gear 31 meshes with the corresponding rack 32 to drive the clamping plate 13 to rotate and unfold to release the storage module 1.

[0029] Please see Figure 5 The one-way valve structure includes a locking unit and an unlocking unit. The locking unit includes a pawl 41 and a stop bar 43. The pawl 41 is rotatably mounted on a support base 11, and a fixed rod is fixedly mounted on the support base 11. The pawl 41 is rotatably connected to the fixed rod. An elastic element 42 is provided between the pawl 41 and the support base 11. The process of the elastic element 42 restoring its deformation drives the pawl 41 to abut against the stop bar 43. When the gear 31 disengages from the corresponding rack 32, the pawl 41 engages with the corresponding gear 31. The elastic element 42 can be a torsion spring or a tension spring. In this embodiment of the present invention, the elastic element 42 is a torsion spring. One end of the torsion spring is fixedly connected to the support base 11, and the other end of the torsion spring is fixedly connected to the pawl 41.

[0030] Please see Figure 6-8 When the support base 11 rises, the gear 31 meshes with the rack 32 at the corresponding position, causing the corresponding clamping plate 13 to rotate and close towards the storage module 1. During this process, the rotating gear 31 causes the pawl 41 at the corresponding position to overcome the elastic force of the elastic element 42 and avoid the teeth of the gear 31, thus allowing the gear 31 to rotate smoothly. When the gear 31 disengages from the rack 32 at the corresponding position, the cover plate closes and abuts against the storage module 1, the elastic element 42 returns to its original deformation, driving the pawl 41 to abut against the stop bar 43. The pawl 41 engages with the teeth of the gear 31, thereby locking the clamping plate 13.

[0031] When the support base 11 descends, the unlocking unit is used to actuate the pawl 41 to unlock the locked clamping plate 13. The unlocking unit includes a sliding pin 51 and a guide plate 52. The sliding pin 51 is fixedly mounted on the pawl 41, and the guide plate 52 is mounted on the housing. When the support base 11 descends, the sliding pin 51 can abut against the guide plate 52, causing the pawl 41 to move away from the gear 31.

[0032] Please see Figure 1-3When the support base 11 descends but the gear 31 is not engaged with the corresponding rack 32, the sliding pin 51 on each pawl 41 first abuts against the guide plate 52 at the corresponding position, so that the corresponding pawl 41 overcomes the elastic force of the elastic element 42 and avoids the gear teeth of the gear 31, releasing the jamming state between the pawl 41 and the gear 31, so as not to interfere with the engagement of the gear 31 with the corresponding rack 32. When the gear 31 engages with the corresponding rack 32, the gear 31 rotates to drive the corresponding clamping plate 13 to rotate and unfold to release the storage module 1.

[0033] Working principle: The storage module 1 placed on the support base 11 is moved by the drive component. During the movement of the support base 11, the gear 31 meshes with the corresponding rack 32. When the support base 11 rises, the gear 31 meshes with the corresponding rack 32 to drive the clamping plate 13 to rotate and clamp the storage module 1. Then, the one-way valve structure can lock the corresponding clamping plate 13. When the support base 11 falls, the one-way valve structure can unlock the corresponding locked clamping plate 13. Then, the gear 31 meshes with the corresponding rack 32 to drive the clamping plate 13 to rotate and release the storage module 1.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
