Description

Technical Field

[0001] This invention relates to the field of energy storage equipment technology, specifically to an outdoor energy storage cabinet structure compatible with multiple inverters. Background Technology

[0002] With the rapid development of the new energy industry, energy storage power stations are increasingly widely used in areas with power shortages and in distributed power supply scenarios. As the core components of energy storage power stations, the adaptability, stability, and ease of maintenance of outdoor integrated installation of energy storage systems and inverters directly determine the overall operating efficiency and service life of the power station.

[0003] Currently, in energy storage power stations, the outdoor installation of inverters and energy storage equipment mostly adopts split cabinets or dedicated integrated cabinets. Among them, integrated outdoor energy storage cabinets have become the mainstream choice due to saving installation space and facilitating centralized maintenance. However, existing outdoor energy storage cabinets still have significant technical defects: First, the inverter compatibility is poor. The inverter mounting brackets on the cabinet have a fixed hole structure, designed specifically for a single brand and model of inverter. However, the spacing and size of the mounting holes of different brands and power inverters on the market vary greatly. When replacing the inverter, it is necessary to completely modify the internal support structure of the cabinet, or even replace the entire outdoor energy storage cabinet, resulting in a double waste of equipment and construction costs. Second, the installation flexibility is low. The fixed structure of the mounting brackets cannot be fine-tuned according to the actual installation requirements of the inverter. Hole deviations are prone to occur during the installation process, resulting in low installation efficiency and making it difficult to meet the needs of rapid construction of energy storage power stations.

[0004] Therefore, with the large-scale construction of energy storage power stations, the use of multi-brand inverters and the subsequent expansion and renovation of power stations are becoming increasingly common. Existing fixed-structure outdoor energy storage cabinets can no longer meet the integrated and highly versatile installation requirements of energy storage systems. Summary of the Invention

[0027] Please see Figures 1 to 3This embodiment provides an outdoor energy storage cabinet structure compatible with multiple inverters, including an outdoor cabinet body 1 and an inverter mounting bracket 2 disposed on one side of the outdoor cabinet body 1. An adjustment groove 3 is provided on the outdoor cabinet body 1 corresponding to the mounting position of the inverter mounting bracket 2. The inverter mounting bracket 2 includes two vertically arranged mounting strips 21, which can slide laterally along the adjustment groove 3. The upper end of each mounting strip 21 has a plurality of first fixing holes 211 spaced apart along its length, which are adapted to the mounting holes of the inverter. The lower end of each mounting strip 21 has a plurality of second fixing holes 212 spaced apart along its length, which are adapted to the mounting holes of the inverter. Of the first fixing holes 211 and the second fixing holes 212, one is a vertically shaped oblong hole, and the other is a round hole. Preferably, the first fixing hole 211 is a round hole, and the second fixing hole 212 is a vertically shaped oblong hole. It should be noted that the present invention does not limit the number of the first fixing holes 211 and the second fixing holes 212 opened on the mounting strip 21, nor the spacing between the first fixing holes 211 and the second fixing holes 212. Those skilled in the art can flexibly set them according to actual application needs.

[0028] The outdoor energy storage cabinet structure provided in this embodiment provides a horizontal adjustment base for the inverter mounting bracket 2 by opening a bracket adjustment groove 3 in the outdoor cabinet body 1. This allows the two vertical mounting strips 21 to slide freely horizontally along the bracket adjustment groove 3, which can accommodate the differences in horizontal mounting hole spacing of inverters of different brands and power. At the same time, the first fixing hole 211 and the second fixing hole 212 arranged at the upper and lower ends of the mounting strips 21 respectively, through the combination design of round holes and vertical waist-shaped holes, can accommodate the differences in vertical mounting hole spacing of different inverters by adjusting the length of the vertical waist-shaped holes. The complementary horizontal and vertical bidirectional adjustment structure breaks the limitation of traditional fixed hole brackets that can only adapt to a single brand and a single model of inverter. It can be compatible with inverters of mainstream specifications on the market, realize the integrated adaptation of outdoor energy storage cabinets to multiple types of inverters, and solve the industry pain point of mixing multi-brand inverters. Replacing the inverter only requires adjusting the lateral position of the mounting strip 21 and the fixed position of the vertical oblong hole to quickly match the mounting hole specifications of the new inverter. No structural modifications to the outdoor cabinet body 1 are required, nor is it necessary to replace the inverter mounting bracket 2. The lateral sliding fit between the bracket adjustment groove 3 and the mounting strip 21, and the length adjustment fit of the vertical oblong hole, are all tool-free quick fine-tuning structures. During installation, it can compensate for machining deviations in the inverter mounting hole positions and positioning deviations in the cabinet installation in real time, avoiding the rework problems caused by hole position deviations of traditional fixed brackets, and greatly improving installation accuracy and efficiency.

[0029] Please see Figure 2 , Figure 3In one embodiment, the bracket adjustment groove 3 includes an upper bracket adjustment slot 31 and a lower bracket fixing slot 32, which are distributed vertically and extend laterally. The length of the upper bracket adjustment slot 31 is the same as the length of the lower bracket fixing slot 32, and the upper bracket adjustment slot 31 and the lower bracket fixing slot 32 are arranged collinearly and aligned vertically. The upper back of the mounting strip 21 is fixed with a hook structure 213 adapted to the upper bracket adjustment slot 31. The hook structure 213 is engaged in the upper bracket adjustment slot 31 and can slide laterally along the upper bracket adjustment slot 31. The lower bracket fixing slot 32 is fixed with a hook structure 213 adapted to the upper bracket adjustment slot 31. The opening of the fixed groove 32 is fixed with a fixing strip 321 extending laterally. The two ends of the fixing strip 321 extend to the two side walls of the lower bracket fixing groove 32. The fixing strip 321 has several transverse waist-shaped holes 3211 spaced apart along its length. The mounting strip 21 has two third fixing holes 214 that cooperate with the transverse waist-shaped holes 3211 at the corresponding positions of the fixing strip 321. The two third fixing holes 214 are located on the left and right sides of the mounting strip 21. The inner cavity of the lower bracket fixing groove 32 forms a space for the fixing member to avoid.

[0030] In this embodiment, the bracket adjustment groove 3 adopts an arrangement in which the upper bracket adjustment slot 31 and the lower bracket fixing slot 32 are aligned vertically. Together with the hook structure 213 on the back of the mounting strip 21 and the third fixing hole 214 on the lower side, a double-layer connection and fixing structure is formed, with the upper end engaging and sliding and the lower end being bolted and locked. Compared with a single bolt connection, this structure allows the connection between the mounting strip 21 and the outdoor cabinet body 1 to be closer and the force to be more even, effectively preventing the mounting strip 21 from tilting or shifting during horizontal adjustment or inverter operation vibration, ensuring the structural stability of the inverter after installation. In addition, the upper and lower grooves are of the same length and vertically aligned, so that the horizontal sliding trajectory of the mounting strip 21 remains straight, avoiding jamming during sliding and improving the smoothness and accuracy of adjustment. The lower bracket fixing groove 32, through the cooperation design of fixing strip 321, horizontal waist-shaped hole 3211 and third fixing hole 214, not only realizes the horizontal position adjustment and bolt locking of the lower end of the mounting strip 21, but also provides additional vertical support for the mounting strip 21 through the supporting role of fixing strip 321, sharing the force of hook structure 213, reducing the wear of hook structure 213 after long-term use, and improving the service life of the entire mounting bracket structure; at the same time, there are two third fixing holes 214, which are respectively located on the left and right sides of the mounting strip 21, and cooperate with the horizontal waist-shaped hole 3211 of fixing strip 321 to form a double-sided locking structure, avoiding unilateral warping of the lower end of the mounting strip 21 and ensuring the fit between the mounting strip 21 and the outdoor cabinet body 1. The inner cavity of the lower bracket fixing groove 32 forms a space to avoid fasteners, which can effectively avoid bolts, nuts and other fasteners that pass through the transverse waist-shaped hole 3211 and the third fixing hole 214. This prevents the fasteners from interfering with the side wall of the groove due to protrusion, ensures a tight fit between the lower end of the mounting strip 21 and the fixing strip 321, and makes the bolt tightening operation smoother, thus improving the efficiency of the installation operation.

[0031] Please see Figure 2 , Figure 3 In one embodiment, a horizontally extending locking strip 311 is fixed to the lower edge of the opening of the upper bracket adjustment slot 31, with both ends of the locking strip 311 extending to the two side walls of the upper bracket adjustment slot 31. The opening of the hook structure 213 faces downward, and the hook structure 213 extends into the upper bracket adjustment slot 31 and engages with the locking strip 311, and the hook structure 213 can slide laterally along the locking strip 311. By adding a horizontal locking strip 311 to the lower edge of the opening of the upper bracket adjustment slot 31, the hook structure 213, with its opening facing downward, precisely engages with the locking strip 311 and slides along it. The locking strip 311 provides a stable sliding guide and vertical limit for the hook structure 213, preventing the hook structure 213 from falling out of the slot. At the same time, it limits the vertical installation position of the mounting strip 21, avoiding misalignment of the inverter mounting holes due to vertical offset of the mounting strip 21, and further improving the accuracy of adjustment and installation. In addition, the inner cavity of the upper bracket adjustment slot 31 forms a hook avoidance space, providing sufficient mobility for the hook structure 213. This effectively avoids the overall structure and connection parts of the hook structure 213 during insertion / removal from the upper bracket adjustment slot 31 and lateral sliding, preventing hard contact or frictional interference between the hook structure 213 and the side wall or bottom of the inner cavity of the upper bracket adjustment slot 31. This ensures the smoothness of the hook structure 213 when sliding laterally along the locking strip 311 and prevents problems such as jamming or sticking.

[0032] Please see Figure 2 In one embodiment, the lower edge of the clip 311 is provided with a plurality of drainage holes 3111 along its length direction, which can quickly drain away rainwater and condensate water accumulated in the upper bracket adjustment slot 31, avoid water accumulation soaking the engagement part of the hook structure 213 and the clip 311, and prevent rust from affecting the sliding flexibility.

[0033] Please see Figure 3 In one embodiment, the hook structure 213 includes two hooks 2131 fixed to the left and right sides of the upper back of the mounting strip 21. The design of the hook structure 213 with two hooks 2131 on the left and right sides makes the clamping force between the upper end of the mounting strip 21 and the upper bracket adjustment slot 31 more balanced, effectively dispersing the force caused by the gravity of the inverter and the vibration of operation, and further enhancing the stability and durability of the connection structure.

[0034] Please see Figure 2 In one embodiment, the lower sidewall of the lower bracket fixing groove 32 is a downwardly inclined slope structure 322, forming a natural drainage guide. The water accumulated in the lower bracket fixing groove 32 can flow out of the groove quickly along the slope, avoiding water accumulation in the groove. At the same time, the fixing strip 321 is fixed to the upper edge of the opening of the lower bracket fixing groove 32 to avoid blocking the drainage path.

[0035] Please see Figure 2 , Figure 3 In one embodiment, the middle part of the mounting strip 21 protrudes forward to form a protrusion 215, a first fixing hole 211 is opened at the upper end of the protrusion 215, a second fixing hole 212 is opened at the lower end of the protrusion 215, and a third fixing hole 214 is opened on the left and right sides of the mounting strip 21; a fastener receiving space 2151 is formed on the back of the protrusion 215. By providing a forward-protruding protrusion 215 in the middle of the mounting strip 21 and forming a fastener receiving space 2151 on its back, the bolts, nuts, and other fasteners connected to the inverter are specifically avoided. This prevents such fasteners from protruding and causing hard interference with the outdoor cabinet body 1, which would prevent the mounting strip 21 from effectively engaging and fitting with the bracket adjustment groove 3. Structurally, this solves the problem of interference between the inverter mounting fasteners and the cabinet body. At the same time, the first fixing hole 211 and the second fixing hole 212 are both opened in the protrusion 215, keeping the connection position between the inverter and the mounting strip 21 away from the outdoor cabinet body 1, providing sufficient operating space for the wiring and maintenance of the inverter, and further improving the convenience of operation and maintenance.

[0036] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
