Description

Technical Field

[0001] This utility model belongs to the technical field of energy storage cabinet equipment, and in particular relates to a battery compartment of an energy storage cabinet. Background Technology

[0002] The working principle of an energy storage cabinet mainly involves two processes: charging and discharging. During charging, electrical energy supplied by an external power source is converted into chemical energy stored in the battery through the charging equipment. During discharging, the chemical energy released by the battery is converted into alternating current (AC) through an inverter to supply power to the load. An energy storage cabinet mainly consists of several parts, including a battery pack, a battery management system, an energy management system, and an inverter. Energy storage cabinets are widely used in: wind and solar power generation with integrated energy storage, grid peak shaving and demand response, microgrids and distributed energy systems, and electric vehicle charging facilities.

[0003] The energy storage cabinet is divided into several important functional units. It is a cabinet structure with a liquid-cooling compartment on the upper part for installing liquid cooling equipment to cool the circulating coolant; a battery compartment in the middle for the detachable installation of various battery packs; and an electrical compartment at the bottom for housing control units and alarm units. The battery compartment is the dominant part, occupying the largest volume. The battery packs are arranged sequentially from top to bottom within the energy storage cabinet. Each battery compartment includes support rails on both sides for supporting the battery pack, which is inserted into the compartment from one side. Since batteries are consumable products, they need to be replaced after a period of use to achieve secondary use. Replacing the battery packs requires pulling them out and inserting them, but the weight of the battery packs makes this operation inconvenient. This invention mainly improves the battery compartment of the energy storage cabinet by modifying the support rails on both sides and adding a roller structure, making the installation and removal of the battery packs more convenient. Utility Model Content

[0004] The purpose of this utility model is to provide a battery compartment for an energy storage cabinet. The main improvement is to modify the battery compartment of the energy storage cabinet by improving the support rails on both sides of the battery compartment and adding a roller structure, making the installation and disassembly of the battery compartment more convenient.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A battery compartment in an energy storage cabinet includes a compartment located in the middle of the cabinet body. Multiple sets of support components are arranged in the compartment from top to bottom at the bottom of each battery compartment to form support.

[0007] Each set of support components includes two horizontally symmetrically arranged support rails, which are located on both sides of a single battery compartment.

[0008] The support rail has an L-shaped cross-section and has an mounting plate for abutting against the inner wall of the compartment, as well as a support plate for supporting the bottom of the battery compartment.

[0009] The support plate is provided with multiple rollers along its length. The rollers are rotatably engaged with the support plate, and the corresponding roller surfaces are used to support the bottom of the battery compartment.

[0010] Furthermore, the support plate is bent inward on its free side to form a folded plate, which is parallel to the mounting plate. The folded plate has an arc-shaped groove for mounting roller shafts, and the mounting plate has a shaft hole corresponding to the position of the arc-shaped groove. A limit plate is fixed to the rear side of the support plate corresponding to the compartment body. The lower side of the limit plate is fixed to the support plate, and the upper side has a bent portion with a rubber sleeve inserted into it.

[0011] Furthermore, a limiting roller is installed on the front side of the support plate corresponding to the compartment body. The limiting roller is mounted on the support plate via an elastic component. The limiting roller is located above the support plate and its horizontal height is higher than that of the roller. The folding plate has a groove for the limiting roller to be accommodated after being pressed. The elastic component is a corrugated elastic strip. One end of the elastic strip is a bushing for fitting and installing the limiting roller shaft, and the other end is a positioning sleeve for fixing it to the support plate.

[0012] The support plate has a positioning plate at the position corresponding to the positioning sleeve. The positioning plate has multiple positioning holes arranged in a row for cooperating with the positioning sleeve and being fixed by bolts.

[0013] This invention has the following advantages: The battery compartment in this invention supports the installed battery boxes through multiple sets of support components, leaving sufficient gaps between the battery boxes for good heat dissipation. Simultaneously, the support components are support rails, which are easy to assemble. The support plates corresponding to the support rails are equipped with rollers, which replace the support plate surface to support the bottom of the battery boxes. When a battery box needs to be replaced due to low efficiency, the rollers make the insertion and removal operation more convenient when inserting or removing the battery box from one side of the compartment.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1-3 As shown: A battery compartment of an energy storage cabinet includes a compartment located in the middle of the cabinet body of the energy storage cabinet 1. Multiple sets of support components are arranged in the compartment from top to bottom and located at the bottom of each battery box 2 to form support. When the battery boxes are supported by the support components, there is a sandwich between each battery box to form air flow and facilitate heat dissipation.

[0023] The single support component includes two horizontally symmetrically arranged support rails 3, which are located on both sides of a single battery compartment 2.

[0024] The support rail 3 has an L-shaped cross-section and has an mounting plate 32 for abutting against the inner wall of the compartment, as well as a support plate 31 for supporting the bottom of the battery compartment 2. The mounting plate and the support plate are vertically arranged on their corresponding sides. The mounting plate has mounting holes that correspond to the holes on the inner side of the compartment for fixing the entire support rail.

[0025] The support plate 31 is provided with multiple rollers 4 along its length. The rollers 4 are rotatably engaged with the support plate 31, and the corresponding roller surfaces are used to support the bottom of the battery compartment 2.

[0026] The battery compartment in this invention uses multiple sets of support components to support the installed battery boxes, ensuring sufficient gaps between them for good heat dissipation. The support components are support rails, facilitating assembly. Rollers are installed on the support plates corresponding to the support rails, replacing the plate surfaces of the support plates to support the bottom of the battery boxes. When a battery box needs replacement due to low efficiency, the rollers facilitate easier insertion and removal by inserting or removing the battery box from one side of the compartment.

[0027] like Figure 4 As shown: The support plate 31 is bent inward on its free side to form a folded plate 33. The folded plate 33 is parallel to the mounting plate 32. The folded plate 33 has an arc-shaped groove 35 for mounting the roller shaft of the roller 4. The mounting plate 32 has a shaft hole 34 corresponding to the position of the arc-shaped groove 35. The two ends of the roller are roller shafts. When installing the roller, first align one side of the roller shaft with the shaft hole and insert it, and then install the other side of the roller shaft into the arc-shaped groove.

[0028] like Figure 5 As shown: A limiting plate 8 is fixed to the rear side of the support plate 31 corresponding to the compartment body. The lower side of the limiting plate 8 is fixed to the support plate 31, and the upper side has a bent part with a rubber sleeve 81 inserted into it. The bent part is bent inward so that after the battery plug is inserted, it is positioned behind the limiting plate and abuts against the rear side of the battery box. The rubber sleeve is installed to prevent squeezing and thus prevent local deformation or wear at the end of the battery box.

[0029] like Figure 4 As shown: A limiting roller 5 is installed on the support plate 31 at the front position of the compartment. The limiting roller 5 is installed on the support plate 31 through an elastic component. The limiting roller 5 is located above the support plate 31 and is horizontally higher than the roller 4. The folding plate 33 has a groove for the limiting roller 5 to be pressed and accommodated. In order to prevent the battery box from easily sliding out of the compartment under the action of the roller, a limiting roller is installed on the front side of the compartment corresponding to the front end of the support plate. The limiting roller is installed through an elastic component. When installing the battery box, the limiting roller is compressed so that the limiting roller is at the same height as the roller, which facilitates the insertion of the battery box. After installation, the limiting roller, which is released from compression, is reset under the action of the elastic component and abuts against the front side of the battery box, thus limiting the battery box and preventing it from slipping.

[0030] The elastic component is a corrugated elastic strip 6. One end of the elastic strip 6 is a bushing 61 for fitting the mounting limit roller 5, and the other end is a positioning sleeve 62 for fixing to the support plate 31. The elastic strip is a metal component, manufactured with a corrugated structure, which is easy to deform in a vertical angle. The support plate 31 has a positioning plate 36 corresponding to the position of the positioning sleeve 62. The positioning plate 36 has multiple positioning holes 37 arranged in a row for cooperating with the positioning sleeve 62 and being fixed by bolts 7. The installation position of the elastic component is adjusted according to the size of the battery box to achieve the best limiting effect and prevent the battery box from shaking back and forth after installation.

[0031] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
