Description

Technical Field

[0001] This utility model relates to the field of energy storage box technology, specifically to a battery energy storage box cabinet. Background Technology

[0002] Energy storage boxes are a key application of new technologies, materials, and equipment in smart substations. They consist of the storage box itself, secondary equipment cabinets (or racks), and auxiliary facilities. After undergoing a series of complex processes including manufacturing, assembly, wiring, and commissioning in the factory, they are transported as a whole to the construction site and installed on the foundation. Currently, fully prefabricated substations using energy storage boxes have changed the traditional electrical system layout, civil engineering design, and construction model of substations. They are built through two main stages: factory prefabrication and on-site installation. Their standardized design, modular combination, industrialized production, and intensive construction lead to substations with high content, low environmental pollution, and refined construction.

[0003] The energy storage box and its internal secondary equipment are integrated by the manufacturer, achieving factory processing, reducing on-site secondary wiring, design, construction, commissioning, and workload, simplifying maintenance, shortening the construction cycle, and effectively supporting power grid construction. The enclosure generally does not have windows; ventilation is achieved through fans and air conditioning. However, heating and ventilation facilities such as air conditioners, electric heaters, and fans should be installed. Windows are recommended for air conditioning, the main control room, and the duty room to facilitate lighting and ventilation.

[0004] However, at present, some manufacturers assemble and weld the metal shell of the energy storage box during the production process, and only perform one finishing. The single degreasing, sandblasting and dust blowing result in obvious and unsightly welds, poor water tightness and poor quality after the energy storage box is assembled and welded. Because the shell is formed by welding, the working intensity is high and it is not easy to maintain in the later stage. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight battery energy storage cabinet that is easy to install and has a tight connection.

[0006] To achieve the above objectives, this utility model is specifically implemented through the following technical solution:

[0007] A battery energy storage cabinet includes a cabinet assembly, a top plate installed on the top surface of the cabinet assembly, and a bottom support installed at the bottom of the cabinet assembly. The cabinet assembly includes a back plate, a left side plate, a right side plate, and a front door plate that are vertically arranged to form the cabinet and fixed by buckles. The left side plate and the right side plate are provided with upper hook buckles on both sides. The back plate and the front door plate are provided with slots on both sides that mate with the upper hook buckles. The front door plate includes a front frame that is buckled to the left and right side plates and a door that is hinged to the front frame. Long screws are vertically installed through the left side plate and the right side plate, and the two ends of the long screws are respectively connected to the top plate and the bottom support.

[0008] Furthermore, a middle plate is vertically installed inside the box panel assembly, parallel to the left and right side plates. A middle limiting plate is horizontally set on both sides of the middle plate, and side limiting plates that cooperate with the limiting plates are set on the inner sides of the left and right side plates.

[0009] Furthermore, the back panel includes a left back panel and a right back panel, which are connected by bolts.

[0010] Furthermore, the cross-sections of the left and right side panels are corrugated.

[0011] Furthermore, the top of the long screw protrudes from the top plate and is fitted with a lifting ring.

[0012] Furthermore, there are four long screws symmetrically installed on the left and right side plates.

[0013] Furthermore, a square tube base frame is installed at the bottom of the base.

[0014] Furthermore, sealing strips are provided on the inner edges of the slots on the left and right side plates.

[0015] Furthermore, ventilation windows were added to the door.

[0016] Furthermore, the enclosure components, top plate, and bottom support are all made of SMC composite material.

[0017] Compared to existing technologies, the energy storage cabinet of this invention is assembled from various molded product parts, allowing for free splicing and making transportation and dismantling more convenient than conventional one-piece welded metal energy storage cabinets. The load-bearing left and right side panels have a corrugated structure, achieving higher structural strength with the same wall thickness. Long through-bolts are embedded on both sides of the side panels, connecting to the bottom support of the cabinet. The upper part of the long bolts passes through the top plate, allowing for direct installation of lifting rings and providing sufficient strength for lifting. The limiting plates on the sides of the side and middle panels are directly formed, serving as load-bearing mounting surfaces. Battery compartments are installed internally via these limiting plates, with each compartment featuring vertical, horizontal, and vertical limiting structures, resulting in stronger integration and a more streamlined internal space. The SMC composite material offers better corrosion resistance than metal, is more adaptable to various complex climates, and provides superior thermal insulation compared to metal.
