Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and more specifically to an energy storage low-voltage control cabinet. Background Technology

[0002] Low-voltage energy storage control cabinets are specialized equipment used for charging and discharging control, status monitoring and protection, and energy dispatch management of low-voltage energy storage systems. They can be divided into two types: multi-group arrangement and individual placement. They are widely used in scenarios such as grid peak shaving and renewable energy access. Energy storage low-voltage control cabinets are typically used in multiple sets. The placement of multiple sets of energy storage low-voltage control cabinets must follow the principles of functional zoning, convenient wiring, and safe operation and maintenance. The core is to plan the layout according to system capacity, control logic, and site conditions. In parallel arrangement, multiple control cabinets are arranged horizontally or vertically along the same axis, with the distance between adjacent control cabinets controlled at an appropriate distance, and all control cabinets facing the same direction to facilitate unified access to the same upper-level control system.

[0003] When used in outdoor environments, the energy storage low-voltage control cabinet is usually hoisted directly to the designated location. However, direct placement results in low stability, and it is prone to tipping over in the event of collisions with external objects or unexpected situations such as strong winds. Therefore, it is necessary to use a mounting base to install and fix the energy storage low-voltage control cabinet to ensure its stability after installation. Utility Model Content

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1-8This utility model provides an energy storage low-voltage control cabinet, including a support frame 3 and at least three control cabinet bodies 1 disposed within the support frame 3. The support frame 3 is a box-shaped structure with an open top. The highest point of the support frame 3 is lower than the lowest point of the door panel of the control cabinet body 1, avoiding obstruction of the door panel opening and closing process by the support frame 3, allowing operators to open or close the door panel of the control cabinet body 1 more smoothly. Fixed support feet 14 are bolted to the bottom of the support frame 3 at the four corners. The fixed support feet 14 utilize the geometric properties of triangles to convert horizontal and vertical loads into diagonal axial forces, significantly improving the lateral displacement and overturning resistance of the support frame 3, making the control cabinet body 1 more stable when placed on the support frame 3. The support frame 3 has openings for the bottom of the control cabinet bodies 1. The hollow section 9 for wiring contains two sets of vertical beams 11 welded inside. A horizontal beam 10 is welded between adjacent vertical beams 11, located in the middle of each beam. This hollow section 9 design makes the wiring connections between the control cabinet bodies 1 simpler and more organized, reducing safety hazards caused by messy wiring and facilitating later maintenance and repair. The horizontal beam 10 and vertical beam 11 combine to form a three-dimensional frame of "lateral load-bearing + longitudinal support." This three-dimensional frame not only provides a stable installation foundation for the control cabinet bodies 1 but also greatly enhances the overall structural strength of the support frame 3. Two connecting plates 15 for separating the control cabinet bodies 1 are detachably installed on the upper surface of the vertical beams 11 using screws. The three cabinets, from left to right, are the first cabinet, the second cabinet, and the third cabinet (e.g., ...). Figure 1 As shown), firstly, the first cabinet is horizontally hoisted from the open end of the support frame 3 so that the first cabinet contacts the closed end of the support frame 3. Then, the two connecting plates 15 are aligned with the two edges of the vertical beam 11 and installed, so that the two connecting plates 15 fixed above the vertical beam 11 form a ventilation gap. Then, hoist the second cabinet from the opening of the support 3 so that the second cabinet contacts the installed connecting plate 15. Next, take two more connecting plates 15, align them and install them to the two edges of another vertical beam 11, and ensure that the second cabinet contacts the connecting plate 15. Finally, the third cabinet is installed in position where it contacts the connecting plate 15, and fixed to the support bracket 3 with screws using the clamping plate 12. At this time, the connecting plate 15 and the support bracket 3 cooperate to form a closed limit on the control cabinet body 1, thereby achieving a stable position constraint.

[0027] To enhance the connection stability of the rain shield 2, in this embodiment (e.g.) Figure 4 As shown), the top of the control cabinet body 1 is provided with a rain shield 2. Each side of the two rain shields 2 is fixed with multiple equally distributed stiffeners 6 by bolts. The stiffeners 6 are made of cold-rolled steel. The stiffeners 6 can effectively distribute the load borne by the rain shield 2. The rain shield 2 can be assembled to the top two sides of the three control cabinet bodies 1 to form an eaves structure. When it is necessary to assemble the three sets of control cabinet bodies 1 onto the support frame 3, the support frame 3 should first be placed stably in the predetermined installation position. The control cabinet body 1 should be slowly lifted and transported to the top of the support frame 3 using a crane, and then slowly lowered. Then, the outer wall of the control cabinet body 1 should be gradually brought into contact with the inner wall of the support frame 3. During this process, personnel should be arranged to observe and adjust to ensure that the control cabinet body 1 is accurately placed into the support frame 3. After the control cabinet body 1 and the support frame 3 are tightly fitted, the connecting plate 15 should be fixed to the upper surface of the vertical beam 11 so that the connecting plate 15 and the support frame 3 cooperate to form a closed and limited position of the control cabinet body 1. After the three sets of control cabinet bodies 1 are assembled, a clamping plate 12 is detachably installed on the short side of the support bracket 3 by screws. The clamping plate 12 has slots 13 at both ends, and the support bracket 3 has threaded holes on both sides that mate with the slots 13. The screws are rotated into the slots 13 through the threaded holes to fix the clamping plate 12 to the support bracket 3. At the same time, the inner side of the clamping plate 12 contacts one side of the control cabinet body 1, forming a closure on the support bracket 3, which enhances the stability of the control cabinet body 1, thereby completing the stable assembly of the control cabinet body 1 on the support bracket 3.

[0028] When the three control cabinet bodies 1 are assembled, two rain shields 2 are fixed to the top of the three control cabinet bodies 1 with screws. When the control cabinet bodies 1 are maintained in the rainy season, one rain shield 2 near the door panel of the control cabinet body 1 can effectively prevent rainwater from entering the cabinet from the door panel, thus avoiding damage to the internal electrical components. At the same time, the eaves structure formed by the rain shield 2 can also protect the maintenance personnel. The other rain shield 2 near the heat dissipation slot of the heat dissipation box 7 can effectively prevent rainwater from entering the heat dissipation box 7 from the heat dissipation slot, thereby preventing damage to the internal components of the control cabinet body 1. It should be noted that the main body of the control cabinet 1 is mainly composed of cabinet structure, electrical control unit, safety protection components, auxiliary support system, etc. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0029] To enhance the stability among multiple control cabinet bodies 1, in this embodiment (e.g.) Figure 2 and Figure 4 As shown), at least two sets of rigid connection components 5 are provided between two adjacent control cabinet bodies 1 for connecting the control cabinet bodies 1. The two sets of rigid connection components 5 are located at the front and back of the control cabinet bodies 1, respectively. At least one set of rigid connection components 5 is installed at the front of the control cabinet body 1 and at the position on one side of the heat sink 7, and at least two sets of rigid connection components 5 are installed at the back of the control cabinet body 1. Among them, rigid connection component 5 (such as Figure 3As shown, the device includes a straight plate 501 that can be detachably installed between two adjacent control cabinet bodies 1 by screws. A protrusion 502 is welded to one side of the straight plate 501 at the middle position. The protrusion 502 is located between the two adjacent control cabinet bodies 1 and contacts the control cabinet body 1. The width of the protrusion 502 is equal to the gap between the adjacent control cabinet bodies 1. The straight plate 501 is fixed to one side of the two adjacent control cabinet bodies 1 by screws. After the straight plate 501 is fixed, the protrusion 502 is precisely embedded in the gap between the adjacent control cabinet bodies 1, closely fitting the side of the control cabinet body 1, effectively preventing the control cabinet body 1 from shaking or shifting during use.

[0030] To solve the heat dissipation problem inside the control cabinet body 1, a heat dissipation box 7 is provided on the top of the control cabinet body 1. The heat dissipation box 7 is existing technology and consists of a cooling fan, a temperature control switch system, auxiliary accessories, etc. Those skilled in the art can set it according to actual needs, which will not be elaborated here. Specifically (e.g.) Figure 2 As shown), the heat sink 7 has multiple equally spaced heat dissipation slots on one side, and multiple equally spaced air inlets 4 are provided on the left and right sides of the control cabinet body 1. A baffle is provided on the outer side of the control cabinet body 1 at the location of the air inlets 4, and the baffle has a louvered, rainproof, perforated structure. The heat dissipation slots and air inlets 4 work together to form good air convection, allowing external cold air to enter the control cabinet body 1 through the air inlets 4, while internal hot air is exhausted through the heat dissipation slots of the heat sink 7, effectively improving the heat dissipation efficiency of the control cabinet body 1. Simultaneously, the louvered, rainproof, perforated baffle design (as shown)... Figure 8 As shown, this can prevent rainwater from directly entering the control cabinet body 1 and causing equipment damage, while also ensuring normal air circulation.

[0031] However, when the control cabinet body 1 is installed outdoors, it may encounter the problem of uneven installation position. The bottom of the support bracket 3 is equipped with a support adjustment component to improve the support stability of the support bracket 3. The support adjustment component includes multiple adjustment feet 8 that are fixed to the bottom of the support bracket 3 by bolts and are evenly distributed. Each adjustment foot 8 has a rotatable adjustment nut at the bottom. By rotating the adjustment nut, the height of the adjustment foot 8 can be adjusted to adapt to different flatness of the installation ground, ensuring that the control cabinet body 1 can maintain a horizontal and stable state. It should be noted that the adjusting foot 8 is existing technology. The adjusting foot 8 consists of a support base, adjusting screw, connecting parts, etc. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0032] The process of fixing and installing multiple control cabinet main bodies 1 involves the following steps: S1: First, fix multiple fixed support legs 14 to the predetermined installation position, then fix the support frame 3 on the multiple fixed support legs 14, and adjust multiple adjusting feet 8 to make the support frame 3 form a stable horizontal state. S2: Then, using a crane, multiple control cabinet bodies 1 are hoisted sequentially to the top of the support frame 3, and slowly lowered into the support frame 3; S3: Specifically, the assembly sequence of multiple control cabinet bodies 1 is as follows: First, the first cabinet body is horizontally hoisted from the open end of the support frame 3, so that the first cabinet body contacts the closed end of the support frame 3. Next, the two connecting plates 15 are aligned and installed with the two edges of the vertical beam 11, so that the two connecting plates 15 fixed above the vertical beam 11 form a ventilation gap. Then, the second cabinet body is hoisted from the open end of the support frame 3, so that the second cabinet body contacts the already installed connecting plates 15. Next, take two more connecting plates 15, align and install them to the two edges of another vertical beam 11, and ensure that the second cabinet body contacts the connecting plates 15. Finally, the third cabinet body is installed in the position that contacts the connecting plates 15. S4: After the three control cabinet bodies 1 are assembled, fix the card plate 12 to the support bracket 3 with screws and make it contact one side of the control cabinet body 1. S5: Finally, fix the two rain shields 2 to the top of the three control cabinet bodies 1 with screws to form an eaves structure.

[0033] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
