Description

Technical Field

[0002] With the large-scale application of renewable energy, the demand for energy storage systems is also increasing. String energy storage systems are better suited to this demand because they can easily integrate energy from different sources and provide a stable power output. Furthermore, string energy storage systems can be combined with smart grid technologies to achieve optimized power dispatch and distribution, improving the efficiency and reliability of the power system.

[0003] String energy storage systems are constructed from multiple converters, with each storage unit capable of independent charging and discharging, enhancing the overall system's reliability and flexibility. Even if one storage unit fails, the remaining units can still operate normally, maintaining the stable operation of the entire system. Furthermore, string energy storage systems can be flexibly expanded to meet specific needs, easily adapting to energy storage requirements in different scenarios.

[0004] In existing technologies, a single converter weighs approximately 80 kg. During on-site disassembly and maintenance, it needs to be lifted 2 to 3 meters, requiring the assistance of tools. Given that the site foundation may be a gravel or muddy surface, the actual handling space is also limited, making it difficult to utilize lifting equipment, forklifts, and other similar tools. Furthermore, on-site power access is inconvenient; therefore, the use of power tools should be avoided as much as possible to reduce tooling costs and ensure that on-site construction is convenient and portable.

[0031] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0032] The embodiments of the utility model will be described below in combination with Figs. 1-2 .

[0033] According to the embodiments of the utility model, a kind of dismounting tool is provided, comprising:

[0034] Fixed seat 1, installation structure is provided on fixed seat 1, installation structure is suitable for at least part of fixed seat 1 is connected in the top of integrated cabinet;

[0035] Slip assembly 2, including slide rail 21 and sliding part 22, slide rail 21 is set on fixed seat 1 along horizontal direction, and sliding part 22 is slidably installed in slide rail 21;

[0036] Hoisting assembly, including pulley assembly 3 and traction 4, pulley assembly 3 is set on sliding part 22, and traction 4 is set on pulley assembly 3, and traction 4 is suitable for driving under the drive of external force to make the piece to be hoisted move along vertical direction.

[0037] It needs to be explained that, in the embodiment, traction 4 selects steel cable. Steel cable has the characteristics of high strength, can withstand greater tension, enough to stably lift about 80 kilograms of converter, guarantee the safety and reliability of hoisting process. Its material is solid and durable, not easy to wear or break in frequent hoisting operation, effectively prolongs the service life of dismounting tool. At the same time, steel cable has certain flexibility, which is convenient for smooth sliding on pulley assembly 3, so that the operation of traction converter moving along vertical direction is more smooth.

[0038] In an alternative embodiment, traction 4 can also be selected from high-strength nylon rope, which also has the advantages of light weight and corrosion resistance, and can play a good role in some scenes with more stringent weight requirements and strong environmental corrosion; Traction 4 can also be selected from iron chain, which has excellent wear resistance and is suitable for use in harsh, frequently used and large wear environments of traction 4. Of course, the material of traction 4 can also be selected flexibly according to different actual situations.

[0039] The utility model discloses an embodiment provides the dismantling tool, and the fixed seat 1 can be at least partially jointed in the integrated cabinet top through the installation structure, and the jointing mode is more convenient to dismount, and even if the ground is the stone muddy road surface and the carrying space is limited in the field environment, can guarantee transportation and stable installation. The slide rail 21 of the sliding component 2 is arranged in the fixed seat 1 along the horizontal direction, and the sliding piece 22 can slide in the slide rail 21, so that the position of the hoisting assembly can be flexibly adjusted, hoisting the inverter at different positions is convenient, and various complex field layouts are adapted. And the pulley assembly 3 of hoisting assembly is arranged on the sliding piece 22, and the traction piece 4 is sleeved on the pulley assembly 3, and the traction piece 4 can be driven by external force, so that the hoisting piece to be hoisted can be moved along the vertical direction, without relying on the hoist, forklift and other difficult to use tooling, and since the traction piece 4 can be manually operated, the problem that electric tools cannot be used due to inconvenient power supply on site is avoided, the tooling cost is greatly reduced, and convenient operation is facilitated, a plurality of problems that the inverter in the group string type energy storage system faces when disassembling and maintaining on site are effectively solved, the work efficiency and convenience are significantly improved, and the maintenance operation of the energy storage system can be smoothly and efficiently carried out.

[0040] Further, the installation structure includes a clamping portion arranged at one side end of the fixed seat 1, and the clamping portion is adapted to clamp the fixed seat 1 to the integrated cabinet.

[0041] As can be easily understood, the clamping portion is arranged at one side end of the fixed seat 1 for clamping the integrated cabinet, so that quick and convenient installation and positioning can be achieved. The clamping mode does not require complex connection operations, so that tooling installation time can be effectively saved, and work efficiency can be improved. In a narrow or inconvenient operating field environment, this simple clamping form is easier to operate, so that the fixed seat 1 can be quickly and stably connected to the integrated cabinet, thereby providing stable support for subsequent hoisting operations.

[0042] In an optional embodiment, the clamping portion can adopt a magnetic attraction structure. The magnetic attraction structure is arranged with magnetic components at corresponding positions of the fixed seat 1 and the integrated cabinet, and the connection between the two is realized by using magnetic force. This mode has advantages in some scenarios where the surface requirements are high, clamping operations are not suitable, or frequent disassembly and installation is required. The installation and disassembly process is smoother, and the integrated cabinet surface will not be damaged. Moreover, the stability of magnetic attraction can meet the fixing requirements of the tooling during hoisting.

[0043] Further, the installation structure further includes a fixing portion arranged at a side end of the fixed seat 1 away from the clamping portion, and a locking member is arranged on the fixing portion, and the locking member is adapted to detachably arrange the fixed seat 1 on the integrated cabinet.

[0044] It is easy to understand that the fixing part is located at the end of the fixing base 1 away from the clamping part and is provided with a locking part, which can enhance the connection stability of the fixing base 1 on the integrated cabinet. During hoisting operation, in the face of various external force disturbances that may occur, such as shaking during hoisting of the converter, dragging force, etc., the locking part can firmly lock the fixing base 1 on the integrated cabinet, effectively preventing the fixing base 1 from shifting or falling off, ensuring the safe and reliable operation of the entire disassembly tooling, and enabling the hoisting operation to proceed smoothly and orderly.

[0045] Further, the fixing base 1 includes a horizontal beam 11, a vertical beam 12, and an inclined beam 13. The horizontal beam 11 is detachably installed on the integrated cabinet in the horizontal direction. The vertical beam 12 is arranged on the horizontal beam 11 in the vertical direction. The inclined beam 13 is connected to the horizontal beam 11 at one end and to the vertical beam 12 at the other end to form a triangular structure.

[0046] It is easy to understand that the fixing base 1 with the horizontal beam 11 in the horizontal direction, the vertical beam 12 in the vertical direction, and the inclined beam 13 connected to the two to form a triangular structure has excellent structural stability. In the complex working conditions of the string-type energy storage system site, such as external force impact and vibration that may be encountered, this structure can effectively disperse stress, prevent the fixing base 1 from deforming or being damaged, ensure that the hoisting assembly and the sliding assembly 2 are always in a stable working state, and ensure the reliability and durability of the entire disassembly tooling, providing a solid foundation for the safe hoisting of the converter.

[0047] In an optional embodiment, a combination structure of a rectangular frame and reinforcing ribs can be used as the fixing base 1. By arranging multiple reinforcing ribs inside the rectangular frame, the overall strength and stiffness of the frame are enhanced. This structure is more suitable for some scenarios that have special requirements for space utilization and are subjected to relatively uniform stress. Under the premise of ensuring a certain structural strength, the size can be adjusted and optimized more flexibly according to the actual installation space and working conditions to meet the needs of different models of integrated cabinets and converter hoisting operations.

[0048] Further, the first end of the horizontal beam 11 is provided with a clamping part, and the second end of the horizontal beam 11 is provided with a fixing part. The first end of the horizontal beam 11 extends and bends in the direction of the integrated cabinet to form an L-shaped clamping part. The second end of the horizontal beam 11 extends in the direction of the integrated cabinet to form a fixing part. The fixing part is provided with a bolt hole. The locking part is a hand-tightened bolt 5. One end of the hand-tightened bolt 5 penetrates the bolt hole and abuts against the integrated cabinet to form a force receiving end.

[0049] It is easy to understand that the beam 11 is provided with an L-shaped clamping part and a fixing part at both ends respectively, and a hand screw bolt 5 is used as a locking part, which has the advantages of convenient installation and strong adaptability. The L-shaped clamping part is convenient for quick clamping on the edge of the integrated cabinet to realize preliminary positioning, and the hand screw bolt 5 can be operated without the help of complex tools. In the string type energy storage system environment where the power supply is inconvenient and the use of tooling is limited, the beam 11 can be efficiently fixed on the integrated cabinet, which can adapt to integrated cabinets of different thicknesses and can flexibly adjust the fastening degree, effectively improving the installation efficiency and universality of the tooling and ensuring that the disassembly tooling can be quickly put into use for inverter hoisting operation. Of course, a clamping part can also be provided at each of the two opposite ends of the beam 11, and the latter clamping part is assembled in a rear assembly form during hoisting to ensure the convenience of installation.

[0050] In an optional embodiment, a combination of buckles and latches can be used as the installation structure. A buckle adapted to the integrated cabinet is provided at each end of the beam 11, and the buckle has a certain elasticity and can be clamped on the edge of the integrated cabinet. Then a latch is passed through the reserved hole of the buckle for secondary locking. This way has the advantages of fast installation speed, simple and light parts, and is suitable for scenes where the installation speed is extremely high and the connection strength is not particularly strict, such as temporary emergency maintenance, etc., which can quickly complete the installation of the fixing seat 1 on the integrated cabinet, and the combination of the latch and the buckle can also ensure the stability of the fixing seat 1 during operation to a certain extent.

[0051] Further, the end of the slide rail 21 away from the fixing seat 1 extends in a direction away from the integrated cabinet and at least partially exposed to the integrated cabinet to form a cantilever end.

[0052] It is easy to understand that the slide rail 21 forms a cantilever end at the end away from the fixing seat 1 and is at least partially exposed to the integrated cabinet, which increases the movable range of the sliding part 22. During the inverter hoisting process, the larger movable range enables the hoisting assembly to adjust the position more flexibly, which facilitates precise lifting of inverters at different positions, especially suitable for situations where inverters are distributed relatively dispersedly or the space layout is irregular, improves the adaptability of the disassembly tooling to complex working conditions, improves the work efficiency, and reduces the inconvenience and time waste caused by limited hoisting position.

[0053] It should be noted that the cantilever end refers to the part of the slide rail 21 that exceeds the connection part of the fixing seat 1 and the integrated cabinet and extends outward. Its length is designed according to the actual hoisting operation requirements, which not only ensures that the sliding part 22 has enough space to cover the required hoisting area, but also considers the structural strength and stability of the cantilever end itself.

[0054] Further, the slide rail 21 and the fixing seat 1 are detachably connected.

[0055] It is easy to understand that the slide rail 21 is detachably connected with the fixed base 1, facilitating transportation and storage. When it is necessary to transfer the disassembly tool to different installation sites, the slide rail 21 can be detached, reducing the overall occupied space, facilitating handling and storage, and reducing transportation cost and difficulty.

[0056] Specifically, in the present embodiment, the slide rail 21 is fixed to the vertical beam 12 by bolts. The bolt connection facilitates installation and disassembly, and when it is necessary to maintain, replace or adjust the slide rail 21 or other related components, the operation is simple and fast, without the need for special tools and complex processes, and can be quickly completed on site. In another alternative embodiment, a connection structure of a clamping groove and a clamping block can be used. A clamping groove is provided on the fixed base 1, and a clamping block is provided at a corresponding position on the slide rail 21. The connection of the two is achieved by sliding the clamping block into the clamping groove, and auxiliary fixing devices such as positioning pins or elastic buckles can be provided in the clamping groove to ensure the stability of the connection. Of course, when the disassembly tool needs to be fixed in the installation site for a long time, the slide rail 21 can also be directly fixed and connected with the vertical beam 12. Here, the specific connection method is not limited.

[0057] Further, the pulley assembly 3 includes a fixed pulley 31 and a movable pulley 32. The fixed pulley 31 is installed on the sliding member 22, one end of the traction member 4 is fixedly connected with the movable pulley 32, and the other end sequentially surrounds the circumferences of the movable pulley 32 and the fixed pulley 31 and then descends to form a force receiving portion.

[0058] It is easy to understand that the pulley assembly 3 adopts the design of the fixed pulley 31 and the movable pulley 32, which can save labor and facilitate control of the traction direction. The fixed pulley 31 changes the direction of the force, so that the operator can apply force at a suitable position. The movable pulley 32 cooperates with the fixed pulley 31 to reduce the force required to lift the converter according to the pulley assembly labor-saving principle, thereby reducing the labor intensity of the operator. When lifting the converter, it is more labor-saving and efficient, and it is also conducive to precisely controlling the lifting position of the converter, ensuring a smooth and safe hoisting process, and improving the practicality and operability of the entire disassembly tool.

[0059] In an alternative embodiment, a single large-diameter pulley can be used as the pulley assembly 3. The large-diameter pulley has a larger wheel groove, which can effectively reduce the frictional resistance between the traction member 4 and the pulley, making the traction process smoother. Its structure is simple, easy to install and maintain, and can be more suitable for scenarios where labor-saving requirements are not high but simplicity and stability of equipment are emphasized, such as when lifting relatively light components or when the tool portability is required to be high. In such cases, a single large-diameter pulley can meet the basic lifting requirements while reducing the volume and weight of the tool, facilitating its use in narrow spaces or frequently moving work environments.

[0060] Further, the movable pulley 32 is provided with an anti-falling device adapted to limit the sliding speed of the traction member 4.

[0061] It is easy to understand that the anti-falling device arranged on the movable pulley 32 improves the safety of the hoisting operation. In the hoisting process of the string-type energy storage system converter, once unexpected situations such as breakage of the traction member 4, failure of the pulley or misoperation of the operator occur, the anti-falling device can quickly limit the sliding speed of the traction member 4, avoid the rapid falling of the converter to be hoisted, effectively prevent the serious consequences such as equipment damage, personnel injury and damage to the surrounding environment caused by the falling of heavy objects, and provide reliable safety protection for the stable operation of the whole disassembly tool.

[0062] Specifically, the anti-falling device can be a centrifugal speed limiter. Its working principle is that when the rotating speed of the movable pulley 32 exceeds the set value, that is, when the sliding speed of the traction member 4 is too fast, the centrifugal block installed on the movable pulley 32 will be thrown outward under the action of centrifugal force and contact the brake drum to generate frictional resistance, thereby limiting the rotating speed of the movable pulley 32 and further limiting the sliding speed of the traction member 4. This structure is relatively compact and sensitive, can start the braking function in time according to the change of the rotating speed of the movable pulley 32, and can adapt to different hoisting conditions and safety requirements by adjusting parameters such as the mass of the centrifugal block and the elastic coefficient of the spring, to ensure that the anti-falling effect can be effectively played in various situations.

[0063] Further, a limiting piece is arranged at the end of the slide rail 21 away from the fixed base 1, and the limiting piece is suitable for limiting the sliding member 22 from disengaging from the slide rail 21.

[0064] It is easy to understand that the limiting piece arranged at one end of the slide rail 21 ensures the normal operation and improves the safety of the sliding assembly 2. During the use of the disassembly tool, the limiting piece can prevent the sliding member 22 from disengaging from the slide rail 21 due to accidental excessive sliding, avoid dangerous situations such as damage of the pulley assembly 3, out-of-control of the traction member 4 and falling of the hoisted member, ensure that the whole hoisting operation can be carried out smoothly and orderly, prolong the service life of the sliding assembly 2 and related components, and reduce the operation interruption and maintenance cost caused by equipment failure.

[0065] Specifically, in this embodiment, a limiting bolt is arranged at the end of the slide rail 21 away from the fixed base 1, and the limiting bolt closes the opening of the slide rail 21 to limit the sliding member 22. The limiting bolt is easy to install and can flexibly adjust its fastening degree according to actual needs, and accurately control the movement range of the sliding member 22. At the same time, the limiting bolt has low cost, effectively controls the overall manufacturing cost of the disassembly tool under the premise of ensuring the limiting function of the sliding member 22, has high stability, can reliably prevent the sliding member 22 from disengaging from the slide rail 21, and ensures the safety and smoothness of the hoisting operation.

[0066] Further, the vertical beam 12 and the inclined beam 13 are detachably connected by bolts. It is easy to understand that when the disassembled tool needs to be transferred and transported, the vertical beam 12 and the inclined beam 13 can be disassembled to reduce the overall space occupation and facilitate carrying to different work sites. During the use of the tool, if the vertical beam 12 or the inclined beam 13 is damaged, the bolt connection mode facilitates quick replacement of the damaged parts, without the need to discard the entire fixing seat 1, thereby reducing the maintenance cost and time, ensuring that the disassembled tool can be restored to normal use state in time, improving the overall service life and use efficiency of the tool, and effectively adapting to the changing field operation requirements and working conditions.

[0067] Further, the contact surface of the cross beam 11 and the integrated cabinet is provided with a protective layer. It is easy to understand that the protective layer provided on the contact surface of the cross beam 11 and the integrated cabinet can effectively protect the surface of the integrated cabinet from damage. During the installation and use of the disassembled tool, friction, extrusion and other forces will be generated between the cross beam 11 and the integrated cabinet. The protective layer can buffer these forces to prevent the cross beam 11 from directly scratching and colliding with the integrated cabinet, thereby preventing the integrated cabinet from being damaged by scratches, dents and other damages.

[0068] Specifically, the protective layer can be made of rubber material and attached to the contact surface of the cross beam 11. Rubber has good elasticity and wear resistance, which can effectively absorb and disperse the pressure and friction generated when the cross beam 11 contacts the integrated cabinet. Anti-slip texture can also be provided on the surface of the rubber protective layer to further enhance the friction between the cross beam 11 and the integrated cabinet, thereby improving the stability and reliability during installation.

[0069] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
