Description

Technical Field

[0001] The present invention relates to the field of energy storage cabinets, and particularly to an outdoor integrated battery energy storage cabinet. Background Art

[0002] An energy storage cabinet is a compact power storage solution that integrates battery packs, a battery management system (BMS), a power conversion system (PCS), and necessary safety protection devices in a sturdy box. It aims to provide users with convenient energy storage and release functions and is applicable to various scenarios from households to industries. The energy storage cabinet can store electrical energy when there is an excess of power and convert it into a stable power output when needed, helping to balance the grid load, provide emergency power support, and enhance the reliability of renewable energy systems.

[0003] Chinese invention patent CN117954767B discloses an energy storage device for an energy storage photovoltaic power station, specifically related to the technical field of energy storage devices.

[0027] Please refer to Figures 1-4 , an outdoor battery energy storage integrated cabinet provided by an embodiment of the present invention includes a cabinet body 1 with a cabinet door 11. Equipment such as a battery pack is installed in the cabinet body 1, and the equipment in the cabinet body 1 can be protected by closing the cabinet door 11. Refer to Figure 1 and Figure 2 , a hollow frame 2 is provided on the top plate of the cabinet body 1. The internal space of the hollow frame 2 is communicated with the cabinet body 1. An electric fan 23 is installed in the mounting frame 21 on the top of the hollow frame 2. Starting the electric fan 23 can discharge external air into the cabinet body 1 to accelerate the air convection speed inside the cabinet body 1 and take out the heat generated by equipment such as the battery pack. Refer to Figure 3 and Figure 4, a condensing pipe 32 is laid in a zigzag manner inside the hollow frame 2, and two liquid storage frames 3 storing condensing liquid are arranged at the upper right position of the top of the cabinet body 1. The two ends of the condensing pipe 32 are respectively connected to the two liquid storage frames 3. The condensing liquid inside the liquid storage frame 3 can flow into the condensing pipe 32. And because the condensing pipe 32 is arranged in a zigzag manner, the residence time of the condensing liquid in the condensing pipe 32 can be prolonged, so that the air inside the hollow frame 2 can be fully cooled. Cooperating with the electric fan 23, the cooled air is blown into the cabinet body 1, enhancing the heat dissipation effect, thereby effectively controlling the temperature inside the cabinet body and protecting sensitive components such as batteries. See Figure 2 , condensers 35 are installed on the tops of the two liquid storage frames 3, and the condensers 35 can ensure that the condensing liquid inside the liquid storage frames 3 continuously remains at a low temperature. See Figure 4 , piston plates 311 are arranged inside the two liquid storage frames 3, and the piston plates 311 can slide along the inner walls of the liquid storage frames 3. A guide post 31 that slides through the liquid storage frame 3 is fixedly arranged on the right side wall of the piston plate 311. The guide post 31 can guide the sliding of the piston plate 311 inside the liquid storage frame 3 to make its sliding more stable. And when the piston plate 311 slides leftward inside the liquid storage frame 3, the condensing liquid inside the current liquid storage frame 3 can be pressed into the condensing pipe 32 and the other liquid storage frame 3. And when the piston plate 311 slides rightward inside the liquid storage frame 3, the condensing liquid can be pumped back into the current liquid storage frame 3 again. In this way, the circulating flow of the condensing liquid in the condensing pipe 32 and the two liquid storage frames 3 can be realized. Cooperating with the refrigeration of the condensers 35, the condensing liquid continuously remains at a low temperature, further improving the heat dissipation efficiency of the device.

[0028] Please refer to Figure 4 , in the embodiment of the present invention, it further includes a reciprocating lead screw 34 rotatably arranged on the top of the cabinet body 1, and a servo motor I 33 installed on the top of the cabinet body 1 and whose output shaft is fixedly connected to the reciprocating lead screw 34. Starting the servo motor I 33 can drive the reciprocating lead screw 34 to rotate. It further includes a connecting plate 312 rotatably connected to the reciprocating lead screw 34 through a thread. See Figure 4 From the perspective of, the front end of the connecting plate 312 is fixedly connected to the nearest guide post 31. When the reciprocating lead screw 34 rotates driven by the servo motor I 33, the connecting plate 312 reciprocates left and right along the thread of the reciprocating lead screw 34, thereby driving the guide post 31 and the piston plate 311 to slide left and right reciprocally inside the liquid storage frame 3, realizing the circulating reflux of the condensing liquid.

[0029] Please refer to Figures 5-8 , in the embodiment of the present invention, ventilation windows 4 are installed on both the left and right side walls of the cabinet body 1. A plurality of blades 41 are rotatably arranged on the ventilation windows 4. When the blades 41 rotate to the vertical state, the ventilation windows 4 are closed by the blades 41. See Figure 7, a sealing sleeve 412 is sleeved on each blade 41 in the ventilation window 4. The sealing sleeve 412 is made of rubber material and fits the inner frame of the ventilation window 4. When the blade 41 rotates to the vertical state, it ensures that the ventilation window 4 is completely closed, and in rainy days, it can prevent rainwater from entering the cabinet body 1 through the ventilation window 4. See Figure 8 , an N-shaped frame 411 is arranged in the middle of each blade 41, and all the N-shaped frames 411 on the same ventilation window 4 are connected by a series rope 42. This enables all the blades 41 to rotate when only one blade 41 is rotated, making the opening and closing of the ventilation window 4 more convenient.

[0030] Please refer to Figure 5 、 Figure 6 and Figure 9 , in the embodiment of the present invention, it further includes a driving structure for controlling the opening and closing of the ventilation window 4.

The sliding frame 51 is slidably arranged on the two columns of the support plate 5. A spring is arranged between the sliding frame 51 and the two columns, and the sliding frame 51 slides while fitting the rear side wall of the cabinet body 1. See Figure 6 , a spur gear 512 is arranged at the end of the uppermost blade 41 on the ventilation window 4. See Figure 9 From the perspective of , the rack 511 meshing with the spur gear 512 is vertically arranged at the left and right ends of the sliding frame 51. Press the sliding frame 51 to make it slide downward, and the rack 511 will follow downward and drive the spur gear 512 to rotate counterclockwise. The blade 41 will then rotate counterclockwise to close, closing the ventilation window 4. And after the sliding frame 51 loses the external force restriction, it will reset under the action of the spring, causing the rack 511 to rise, the spur gear 512 and the blade 41 to rotate clockwise, and the ventilation window 4 will also open accordingly. See Figure 9 , the screw 52 is rotatably arranged on the rear side wall of the cabinet body 1, and a servo motor II 53 with an output shaft fixedly connected to the screw 52 is also installed on the cabinet body 1. A lower pressing plate 54 is also rotatably arranged on the screw 52. The lower pressing plate 54 is in contact with the top end of the sliding frame 51, and the contact part is set as an inclined surface. See Figure 9 From the perspective of , driving the screw 52 to rotate clockwise by the servo motor II 53 can make the lower pressing plate 54 slide to the right along the screw 52, and under the pressure of its inclined surface part, the sliding frame 51 slides downward, cooperating with the rack 511 and the spur gear 512 to realize the automatic closing of the ventilation window 4. See Figure 5 , six one-way exhaust valves 6 are installed on both the left and right side walls of the cabinet body 1. When the ventilation window 4 is closed, the hot air inside the cabinet body 1 can still be discharged outward through the one-way exhaust valves 6.

[0031] Please refer to Figure 1 andFigure 10 In the embodiment of the present invention, it further includes an energy storage structure arranged on the top of the cabinet body 1. The energy storage structure includes two trapezoidal plates 12 symmetrically arranged on the top of the cabinet body 1, and a photovoltaic panel 13 installed between the two trapezoidal plates 12. The photovoltaic panel 13 is electrically connected to the energy storage device in the cabinet body 1 and can provide additional energy for the energy storage device. Refer to Figure 1 for the perspective, and the photovoltaic panel 13 is inclined backward and downward. A diversion plate 14 inclined forward and downward is arranged at the front end of the photovoltaic panel 13, which not only facilitates the rapid discharge of rainwater but also can guide the water flow away from the device. Refer to Figure 10 , a guide rod 56 is also arranged at the higher end of the photovoltaic panel 13. A scraper 55 that fits the surface of the photovoltaic panel 13 is slidably arranged on the guide rod 56, and the other end of the scraper 55 is fixedly connected to the pressing plate 54. While the servo motor II 53 and the screw rod 52 cooperate to drive the pressing plate 54 to move, the scraper 55 will also move accordingly and clean the dirt and accumulated water on the photovoltaic panel 13.

[0032] Please refer to Figure 2 , in the embodiment of the present invention, a dust-proof filter plate 22 is arranged on the mounting frame 21. The dust-proof filter plate 22 can block foreign objects and dust from the outside when the electric fan 23 exhausts air to the cabinet body 1, preventing foreign objects and dust from entering the cabinet body 1 along with the air flow and damaging the internal equipment. A scraping frame 7 is also arranged on the guide post 31 connected to the connecting plate 312. The scraping frame 7 fits the upper surface of the dust-proof filter plate 22. A collection frame 71 adapted to the size of the mounting frame 21 is also arranged on the top of the hollow frame 2. The collection frame 71 is located on the left side of the dust-proof filter plate 22. When the servo motor I 33 and the reciprocating lead screw 34 cooperate to drive the connecting plate 312 and the guide post 31 to move to the left, the scraping frame 7 will move to the left accordingly and push the impurities accumulated on the dust-proof filter plate 22 into the collection frame 71.
