Description

Technical Field

[0001] The present invention relates to the technical field of protection devices, and in particular to an IP65 outdoor energy storage cabinet. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] With the rapid development of renewable energy and the construction of smart grids, as new energy generation capacity gradually increases and continues to connect to the grid, outdoor energy storage systems are becoming increasingly widely used in the energy sector. Due to the unique characteristics of large-scale energy storage projects, outdoor energy storage projects are generally built outdoors in complex and harsh environments. To ensure the safe and reliable operation of outdoor energy storage cabinets, the cabinet protection level is particularly important.

[0004] Outdoor energy storage systems typically consist of outdoor cabinets or containers that house electrical equipment, including batteries, fire protection, power distribution, and control systems. Their structure must take into account strength, corrosion resistance, heat dissipation, dustproofing, and waterproofing. The most common protection level for existing outdoor energy storage systems is IP54.

[0005] The prior art provides a waterproof and dustproof power distribution cabinet, comprising a cabinet body and an axial flow fan. Both sides of the cabinet body utilize an upper and lower split-layer structure, with the air inlet located on the inner wall of the lower layer and the air outlet located on the inner wall of the upper layer. Both the upper and lower layers are covered with waterproof partitions with louvers, and the positions of the air inlet and outlet located on the inner walls of the upper and lower layers form a height difference with the positions of the louvers on the waterproof partitions covering them. In addition, the cabinet body may also be equipped with a temperature and humidity controller and a heater, and a dust filter replacement slot is provided above the exhaust and air inlet. This prior art waterproofing and dustproofing is primarily achieved through waterproof partitions with louvers located on the air inlet and outlet. However, with the louvered installation, the waterproofing performance can only reach IP54. With the increasing national requirements for the waterproofing and dustproofing of energy storage cabinets, there is an urgent need to design energy storage cabinets with more advanced waterproof structures. Summary of the Invention

[0006] The purpose of the present invention is to provide an IP65 outdoor energy storage cabinet with an improved waterproof and dustproof level to meet higher waterproof and dustproof requirements, in order to address the problem that the waterproof level of the current energy storage cabinet is difficult to meet higher standard requirements.

[0007] The technical solutions of the present invention are as follows:

[0008] An IP65 outdoor energy storage cabinet includes an energy storage component and a shell, wherein the shell is provided with an air inlet and an air outlet.

[0009] The air inlet is provided with a protective assembly, the protective assembly including an inner side facing the energy storage component and an outer side away from the energy storage component, and the protective assembly includes, from the outer side to the inner side, a first baffle provided on the outermost side, a second baffle provided opposite to the first baffle, and a filter provided close to the second baffle;

[0010] The first baffle includes a plurality of inwardly facing recessed portions, wherein the recessed portions include a first side plate located below, a second side plate located above, and a third side plate connected to the first side plate and the second side plate respectively.

[0011] A first-stage air inlet is provided on the second side panel located above. When the wind reaches the first-stage air inlet, a portion of the water droplets carried by the airflow will fall due to gravity and will not enter the protective component through the air inlet.

[0012] The second baffle includes a plurality of outwardly facing protrusions, wherein the plurality of protrusions and the recessed portions are arranged alternately;

[0013] A second-stage air inlet hole is arranged between the several protrusions, and the second-stage air inlet holes and the first-stage air inlet holes are staggered in the height direction. When the water droplets carried by the air flow reach the second-stage air inlet holes from the first-stage air inlet holes, the water droplets are separated from the air flow due to gravity and the acceleration of the air flow, and thus will not enter the second-stage air inlet holes.

[0014] Preferably, the filter element is synthetic fiber filter cotton, non-woven filter cotton, glass fiber filter cotton or activated carbon filter cotton.

[0015] The third side plate of the recessed portion is inclined toward the direction of gravity, and the protruding portion includes a horizontally arranged fifth side plate and a fourth side plate inclined toward the direction of gravity. The third side plate and the fourth side plate can guide the dripping water droplets to drip.

[0016] According to a preferred embodiment, the air inlet and the air outlet are respectively arranged on two opposite sides of the energy storage component, so that air can flow through the energy storage component to dissipate heat from the energy storage component.

[0017] According to a preferred embodiment, the housing further includes an openable door leaf and a sealing frame corresponding to the door leaf, and the sealing frame is configured as a flap frame.

[0018] According to a preferred embodiment, a sealing strip is provided on the side surface of the flange that contacts the door leaf.

[0019] According to a preferred embodiment, the shell further includes a top waterproof cover, and the four upper corners of the waterproof cover are respectively provided with hanging holes.

[0020] According to a preferred embodiment, a mounting base is provided at the bottom of the housing.

[0021] According to a preferred embodiment, a transport hole is opened on the mounting base for transport by forklift.

[0022] Compared with the existing technology, the beneficial effects of the present invention are:

[0023] 1. An IP65 outdoor energy storage cabinet, by changing the structure of the first baffle of the protective assembly, setting the first-stage air inlet at the top, and setting the second-stage air inlet and staggering the first-stage air inlet and the second-stage air inlet, can greatly reduce the ingress of water flow and improve the waterproof performance of the shell;

[0024] 2. An IP65 outdoor energy storage cabinet, based on the staggered arrangement of the first-stage air inlet and the second-stage air inlet, dust has a large angle turn when reaching the second-stage air inlet from the first-stage air inlet, so that the lighter dust is separated from the airflow and thrown out by the action of centrifugal force, reducing the amount of dust reaching the second-stage air inlet, thereby reducing the filtering pressure of the filter cotton and improving the dustproof performance.

[0032] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0033] Example 1

[0034] The energy storage component 100 generates heat, which needs to be dissipated during use, thus requiring airflow. However, dust and moisture can damage the energy storage component 100, so it is necessary to prevent moisture and dust from entering the energy storage component 100 with the cooling airflow. Since energy storage components 100 are often installed outdoors, where climatic conditions are more severe, the environment generates a lot of dust and is also exposed to rain, placing high demands on the energy storage cabinet's waterproof and dustproof capabilities.

[0035] This application provides an IP65 outdoor energy storage cabinet, such as Figure 1 As shown, the present invention comprises an energy storage component 100 and a housing 200. The housing 200 covers the outside of the energy storage component 100 to protect the energy storage component 100. The housing 200 is provided with an air inlet 210 and an air outlet 220. Airflow enters the housing 200 through the air inlet 210, flows through the energy storage component 100, and then flows out through the air outlet 220, removing heat from the energy storage component 100 to achieve heat dissipation.

[0036] According to a preferred embodiment, a protective component 300 is provided on the air inlet 210 to block external moisture and dust and protect the energy storage component 100. The protective component 300 includes an inner side facing the energy storage component 100 and an outer side facing away from the energy storage component 100. Figure 2 and Figure 4As shown, the protective assembly 300 includes, from the outside to the inside, a first baffle 310 disposed on the outermost side, a second baffle 320 disposed opposite the first baffle 310, and a filter 330 disposed closely to the second baffle 320. External air passes through the first baffle 310, the second baffle 320, and the filter 330 in sequence before entering the housing 200.

[0037] According to a preferred embodiment, the first baffle 310 includes a plurality of inwardly facing recessed portions 311, which block external water flow through the recessed portions 311. The recessed portions 311 include a first side plate 3111 located at the bottom, a second side plate 3112 located at the top, and a third side plate 3113 connected to the first side plate 3111 and the second side plate 3112, respectively.

[0038] Preferably, the upper second side panel 3112 is provided with a first-stage air inlet 312. When wind reaches the first-stage air inlet 312, some water droplets carried by the airflow will fall due to gravity and will not enter the protective assembly 300 through the air inlet 210. Preferably, the second side panel 3112 is shorter than the first side panel 3111, so that even if external water accidentally enters the protective assembly 300 through the first-stage air inlet 210, it will collide with the first side panel 3111 in the upper recess 311 during movement and fall out.

[0039] According to a preferred embodiment, the second baffle 320 includes a plurality of outwardly facing protrusions 321, and the plurality of protrusions 321 are arranged alternately with the recesses 311. Figure 3 As shown, second-stage air inlet holes 322 are provided between the plurality of protrusions 321, and the second-stage air inlet holes 322 and the first-stage air inlet holes 312 are staggered in the height direction. In the process of water droplets carried by the airflow reaching the second-stage air inlet holes 322 from the first-stage air inlet holes 312, the water droplets are separated from the airflow due to gravity and the acceleration of the airflow, and thus will not enter the second-stage air inlet holes 322; on sunny days when there is no water flow, lighter dust will also be separated from the airflow due to the centrifugal force generated by the deflection of the airflow, thereby reducing the amount of dust reaching the second-stage air inlet holes.

[0040] Preferably, the filter element 330 is a synthetic fiber filter, non-woven fabric filter, glass fiber filter, or activated carbon filter. Airflow through the second-stage air inlet 322 must pass through the filter element 330 before reaching the interior of the housing 200. Dust is intercepted by the filter element due to static electricity and large particles. Water droplets that accidentally enter the second-stage air inlet 322 are also absorbed by the filter element 330 and prevented from entering the housing 200 and coming into contact with the energy storage component 100.

[0041] Preferably, the third side plate 3113 of the recessed portion 311 is inclined toward the direction of gravity, and a drain port is provided at the bottom of the recessed portion 311. The protruding portion 321 includes a fifth side plate 3212 disposed horizontally and a fourth side plate 3211 inclined toward the direction of gravity. The third side plate 3113 and the fourth side plate 3211 can guide water droplets to be discharged from the drain hole 340.

[0042] According to a preferred embodiment, Figure 1 As shown, the air inlet 210 and the air outlet 220 are respectively arranged on two opposite sides of the energy storage component 100 , so that the air flow can flow through the energy storage component 100 to the maximum extent to dissipate heat from the energy storage component 100 .

[0043] According to a preferred embodiment, due to the need for configuration and maintenance of the internal energy storage component 100, an openable door 230 is provided, which also increases the probability of external air and water entering the interior of the housing 200. Figure 5 As shown, a sealing frame 240 corresponding to the door leaf 230 is provided on the housing 200. The sealing frame 240 is configured as a flap frame, thereby extending the path for water to enter the housing 200 and increasing the difficulty of water entering the housing 200. Preferably, a sealing strip 241 is provided on the side of the flap frame that contacts the door leaf 230. The elastic sealing strip 241 increases the tightness of the connection between the door leaf 230 and the sealing frame 240, preventing water from flowing into the interior of the housing 200, thereby improving the waterproof performance of the door leaf 230.

[0044] According to a preferred embodiment, the housing 200 further includes a top waterproof cover 250 , and four upper corners of the waterproof cover are respectively provided with hanging holes 260 .

[0045] According to a preferred embodiment, a mounting base 270 is provided at the bottom of the housing 200 for fixing the housing.

[0046] According to a preferred embodiment, a transport hole is opened on the mounting base 270 for transport by a forklift, thereby facilitating the movement of the energy storage cabinet.

[0047] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
