Description

Technical Field

[0001] The utility model relates to the technical field of outdoor energy storage cabinet design, in particular to an outdoor energy storage cabinet. Background Art

[0002] With the rapid development of renewable energy technologies, outdoor energy storage cabinets are increasingly widely used in energy management systems. Modern outdoor energy storage cabinets integrate battery packs, power converters (PCS), battery management systems (BMS), energy management systems (EMS), monitoring and control systems, and other auxiliary systems, enabling efficient energy storage and management. However, with the improvement of system integration, the structural design of energy storage cabinets also faces many challenges.

[0003] In order to accommodate various systems and devices, a large number of columns and beams often need to be arranged inside the cabinet, which makes the internal structure of the energy storage cabinet too cumbersome, not only increasing the difficulty of installation and transportation, but also resulting in unreasonable equipment layout and affecting the overall performance of the system. At the same time, since the connection between the side plates and columns of the energy storage cabinet requires drilling and fixing, a large number of holes will damage the overall sealing performance of the cabinet body, causing the cabinet body to be vulnerable to erosion by factors such as moisture and dust in the outdoor environment. This not only affects the normal operation of internal electrical equipment but also shortens the service life of the system.

[0004] The battery compartment and the PCS system are placed in the same space. During the operation of the battery, a large amount of heat is generated. If the thermal management is improper, it may cause the equipment to overheat, thus triggering safety problems. Summary of the Utility Model

Detailed implementation manners

[0040] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in combination with embodiments and drawings. The illustrative embodiments and descriptions of the present utility model are only used to explain the present utility model and are not intended to limit the present utility model.

[0041] Example 1

[0042] Reference Figures 1-6 , an outdoor energy storage cabinet, comprising a top cover 104 assembly 1, a first side plate assembly 2, a second side plate assembly 3, a base assembly 4, a stabilizing assembly 5 and a door panel assembly 6.

[0043] The top cover 104 assembly 1 includes a top cover reinforcing rib assembly 101, a first cross beam 102, a second cross beam 103 and a top cover 104. The top cover reinforcing rib assembly 101 is disposed at the bottom of the top cover 104. The top cover reinforcing rib assembly 101 adopts a grid-shaped reinforcing rib and is disposed at the bottom of the top cover 104. The grid-shaped reinforcing rib forms an intersecting support network inside the top cover 104, effectively improving the overall strength and rigidity of the top cover 104, preventing the top cover 104 from bending or deforming when subjected to external forces. Through the multi-point support of the reinforcing ribs, the top cover 104 can evenly disperse the stress it bears, thereby enhancing its compressive resistance and ensuring that the top cover 104 maintains a stable shape during long-term use.

[0044] A lifting lug 15 is provided on the top cover 104, and the lifting lug 15 is bolted and welded to the top cover reinforcing rib assembly 101.

[0045] The first cross beam 102 is disposed at the bottom of the long side on one side of the top cover 104, and the second cross beam 103 is disposed at the bottom of the long side on the other side of the top cover 104. One end of the first cross beam 102 is connected to one side of the top of the first side plate assembly 2, and the other end of the first cross beam 102 is connected to one side of the top of the second side plate assembly 3. One end of the second cross beam 103 is connected to the other side of the top of the first side plate assembly 2, and the other end of the second cross beam 103 is connected to the other side of the top of the second side plate assembly 3. The outer edges around the top cover 104 are inwardly buckled. The first cross beam 102 and the second cross beam 103 are respectively disposed at the bottom of the long sides on both sides of the top cover 104, playing a role in supporting the structure of the top cover 104. These cross beams connect the top cover 104 to the tops of the first side plate assembly 2 and the second side plate assembly 3, forming a stable frame structure. The connection between the cross beam and the side plate ensures a firm connection between the top cover 104 and the side plate, further enhancing the structural integrity of the entire energy storage cabinet and preventing the top cover 104 from loosening or falling off in a harsh environment. In addition, the outer edges around the top cover 104 adopt an inward buckling design to ensure the sealing between the top cover 104 and the side plate. The inward buckling design not only prevents external factors such as rain and dust from invading the energy storage cabinet, but also improves the wind resistance of the energy storage cabinet in the outdoor environment, protecting the internal equipment from the influence of the external environment.

[0046] The first side plate assembly 2 includes a first side plate 201, a first side plate vertical rib 202, and a second side plate vertical rib 203. The outer edges around the first side plate 201 are inwardly buckled. The first side plate vertical rib 202 and the second side plate vertical rib 203 are arranged inside the first side plate 201, and the tops of the first vertical rib and the second vertical rib are fixedly connected to the inner buckled edge at the top of the first side plate 201, and the bottoms of the first vertical rib and the second vertical rib are fixedly connected to the inner buckled edge at the bottom of the first side plate 201. The top of the first side plate 201 is fixedly connected to one side of the top cover 104, one end of the first cross beam 102, and one end of the second cross beam 103 respectively. Among them, the first side plate vertical rib 202 and the second side plate vertical rib 203 form longitudinal reinforcement for the first side plate 201 by being arranged inside the first side plate 201 and fixed to the inner buckled edges at the top and bottom. The vertical strengthening structure can effectively improve the overall rigidity of the side plate, enhance its ability to withstand vertical and lateral pressures, and prevent the side plate from deforming or warping due to uneven stress during use. The top of the side plate is connected to one end of the top cover 104, the first cross beam 102, and the second cross beam 103 through the inner buckled edge. The inner buckled edge design realizes the tight combination between the side plate and the top cover 104 and the cross beam, making the side plate more stable in the entire energy storage cabinet structure, and avoiding connection loosening or fatigue problems caused by traditional welding methods. The inward buckling design of the outer edges around the side plate reduces the gap between the side plate and other structural components, further improving the sealing performance of the energy storage cabinet. Good sealing performance can effectively prevent the intrusion of external environmental factors such as rain and dust, protect the internal equipment, and extend the service life of the energy storage cabinet.

[0047] The second side plate assembly 3 includes a second side plate 301, a third side plate vertical rib 302, and a fourth side plate vertical rib 303. The outer edges around the second side plate 301 are inwardly buckled. The third side plate vertical rib 302 and the fourth side plate vertical rib 303 are arranged inside the second side plate 301. The tops of the third vertical rib and the fourth vertical rib are fixedly connected to the inner buckling edge at the top of the second side plate 301, and the bottoms of the third vertical rib and the fourth vertical rib are fixedly connected to the inner buckling edge at the bottom of the second side plate 301. The top of the second side plate 301 is fixedly connected to the other side of the top cover 104, the other end of the first cross beam 102, and the other end of the second cross beam 103 respectively. The third side plate vertical rib 302 and the fourth side plate vertical rib 303 are arranged inside the second side plate 301 and are connected to the top and the bottom through the inner buckling edges respectively. These vertical ribs provide longitudinal support, significantly enhancing the rigidity of the second side plate 301, enabling it to better withstand longitudinal and lateral pressures, and preventing bending or deformation during transportation, installation, and use. The top of the second side plate 301 is fixedly connected to the other side of the top cover 104, the other end of the first cross beam 102, and the other end of the second cross beam 103 through the inner buckling edge. The design of the inner buckling edge realizes the tight combination between the side plate and the top cover 104 and the cross beams, making the entire structure more stable and avoiding loosening or structural fatigue caused by insecure connection. This connection method also ensures the uniform distribution of forces among the side plate, the cross beams, and the top cover 104, further enhancing the stability of the overall structure of the energy storage cabinet. The inward buckling design of the outer edges around the second side plate 301 reduces the gaps between the side plate and other structural components, thereby enhancing the sealing performance of the energy storage cabinet, preventing external factors such as rainwater and dust from invading the interior of the energy storage cabinet, protecting the battery pack and electrical equipment, and extending the service life of the equipment. At the same time, the inner buckling edge design not only ensures the strength and stability of the structure but also makes the connection between the side plate and other components smoother and more aesthetically pleasing, avoiding the visual clutter caused by external protrusions or irregular connections and improving the overall appearance effect of the energy storage cabinet.

[0048] The base assembly 4 includes a first base cross beam 401, a second base cross beam 402, a first base vertical beam 403, a second base vertical beam 404, a third base vertical beam 405, a fourth base vertical beam 406, a fifth base vertical beam 407 and a base cover plate 408. Among them, the first base cross beam 401, the first base vertical beam 403, the second base cross beam 402, and the second base vertical beam 404 are fixedly connected end to end in sequence. The third base vertical beam 405, the fourth base vertical beam 406, and the fifth base vertical beam 407 are respectively fixed between the first base cross beam 401 and the second base cross beam 402. The base cover plate 408 is fixed on the first base cross beam 401, the first base vertical beam 403, the second base cross beam 402, and the second base vertical beam 404. The top of one short side of the base cover plate 408 is fixedly connected to the bottom of the first side plate 201, and the top of the other short side of the base cover plate 408 is fixedly connected to the bottom of the second side plate 301. The first base cross beam 401, the second base cross beam 402, the first base vertical beam 403, and the second base vertical beam 404 are fixedly connected end to end in sequence, forming the basic frame structure of the base. This frame provides a firm foundation for the entire energy storage cabinet, can evenly disperse the weight of the energy storage cabinet, and ensures that the cabinet body remains stable during installation and use, and is not prone to tilting or moving. The third base vertical beam 405, the fourth base vertical beam 406, and the fifth base vertical beam 407 are arranged between the first base cross beam 401 and the second base cross beam 402, providing additional vertical support for the base. The multi-vertical beam structure formed not only improves the rigidity of the base, enabling it to bear the weight of the internal equipment of the energy storage cabinet and the pressure of the external environment, but also enhances the overall load-bearing capacity of the base. The base cover plate 408 is fixedly connected to the first base cross beam 401, the first base vertical beam 403, the second base cross beam 402, and the second base vertical beam 404, forming a complete base plane. One short side of the base cover plate 408 is fixedly connected to the bottom of the first side plate 201, and the other short side is fixedly connected to the bottom of the second side plate 301. This ensures a tight combination between the side plate and the base, avoiding problems such as the instability of the cabinet body or air leakage and water leakage caused by insecure connection. The connection between the base cover plate 408 and the base beams and vertical beams forms a closed base structure. The closed design not only improves the sealing performance of the base, preventing external dust and moisture from entering, but also can protect the internal circuits and equipment from the environment. The setting of multiple vertical beams makes the base structure have stronger anti-impact and anti-vibration capabilities, which has an important buffering and protective effect on the external impacts and vibrations encountered during the transportation, installation, and use of the energy storage cabinet, and extends the service life of the energy storage cabinet and its internal equipment.

[0049] The stabilizing component 5 includes a first vertical column 501, a second vertical column 502, a third vertical column 503, and a fourth vertical column 504. The first vertical column 501 and the third vertical column 503 are arranged at intervals between the first base crossbeam 401 and the first crossbeam 102. The second vertical column 502 and the fourth vertical column 504 are arranged at intervals between the second base crossbeam 402 and the second crossbeam 103. The first vertical column 501, the third vertical column 503, the second vertical column 502, and the fourth vertical column 504 are symmetrically arranged. The first vertical column 501, the second vertical column 502, the third vertical column 503, and the fourth vertical column 504 are arranged at intervals between the first base crossbeam 401 and the first crossbeam 102, and between the second base crossbeam 402 and the second crossbeam 103, playing a role in support and stability. By providing additional support at key positions, these vertical columns enhance the overall strength of the energy storage cabinet frame. The symmetric arrangement design of the vertical columns makes the force on the cabinet body more uniform. Whether it is the weight from the top cover 104, the pressure from the side plates, or the weight of the internal equipment in the cabinet, it will be evenly transmitted to the base through these vertical columns, thereby reducing local stress concentration and lowering the risk of structural instability. Since the energy storage cabinet is usually placed outdoors and needs to have strong wind and earthquake resistance capabilities, the vertical columns in the stabilizing component 5 make the energy storage cabinet still maintain structural stability and will not experience violent shaking or displacement when affected by external environments such as strong winds or earthquakes, ensuring the safety of the internal equipment. In addition, the vertical columns not only play a supporting role but also provide support points for the space separation inside the cabinet body and the installation of equipment. Internal structures including but not limited to partitions 7 and mounting plates can be fixed through these vertical columns, making the layout of the internal space more reasonable and the equipment installation more stable.

[0050] A partition 7 is provided on the top of the base cover plate 408. The two sides of the partition 7 are respectively fixed between the first upright column 501 and the third upright column 503. The partition 7 and the first side plate 201 form a battery compartment, and the partition 7 and the second side plate 301 form an electrical equipment compartment. In the electrical equipment compartment, a first mounting plate 8 and a second mounting plate 9 are arranged in sequence from top to bottom. The two sides of the first mounting plate 8 are respectively fixed on the second side plate 301 and the partition 7, and the two sides of the second mounting plate 9 are respectively fixed on the second side plate 301 and the partition 7. A BMS is placed on the first mounting plate 8, and an EMS is placed on the second mounting plate 9. A duct support 10 is provided at the bottom of the battery compartment, and an air-conditioning air duct 11 is installed on the duct support 10. The air inlet of the air-conditioning air duct 11 is connected to the air conditioner 13. The partition 7 divides the internal space of the energy storage cabinet into two independent areas, namely the battery compartment and the electrical equipment compartment, effectively reducing the heat and electromagnetic interference between the battery and the electrical equipment, which helps to improve the safety of the energy storage cabinet and the stability of the equipment. The fixing method of the partition 7 firmly connects it between the first upright column 501 and the third upright column 503, increasing the overall rigidity and stability of the cabinet body. The electrical equipment compartment is designed to be provided with the first mounting plate 8 and the second mounting plate 9 in sequence from top to bottom, which are used to place the battery management system (BMS) and the energy management system (EMS) respectively, ensuring sufficient operation and maintenance space between different electrical equipment, and at the same time facilitating the cable connection and wiring between the equipment, simplifying the installation process. The first mounting plate 8 and the second mounting plate 9 are respectively fixed between the partition 7 and the second side plate 301, enabling the firm installation of the BMS and EMS devices, avoiding the displacement or vibration of the devices during transportation or operation, which may affect the stable operation of the system. The duct support 10 is installed at the bottom of the battery compartment and is used to fix the air-conditioning air duct 11. By forming a stable duct structure at the bottom of the battery compartment, it ensures that the cold air can be evenly distributed throughout the battery compartment, keeping the temperature of the battery pack within a reasonable range, preventing overheating, and improving the operation efficiency and safety of the battery. The air inlet of the air-conditioning air duct 11 is connected to the air conditioner 13, which enables the air conditioner 13 to directly send the cold air into the battery compartment through the air duct, forming an effective cooling cycle. This cooling method improves the cooling efficiency and avoids equipment failures caused by poor local heat dissipation.

[0051] The door panel assembly 6 is composed of a plurality of front doors and rear doors, corresponding to the front and rear sides of the battery compartment and the electrical equipment compartment respectively.
