DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0025] See also Figures 1-6A screening tool for short-board battery cells in an energy storage system includes a battery management body 1 and two mounting plates 2 installed at both ends of the battery management body 1. The bottom surface of the battery management body 1 is provided with a mounting opening 101. The bottom surface of the circuit board inside the battery management body 1 is fixedly connected to the heat dissipation fin 3. The other end of the heat dissipation fin 3 passes through the mounting opening 101 and is fixedly connected to the inner wall of the mounting opening 101. The bottom surface of the battery management body 1 is connected to the processing box 4. The bottom surface of the processing box 4 is provided with a heat dissipation port 401. The heat dissipation port 401 is matched and aligned with the heat dissipation fin 3. The inner wall of the processing box 4 is connected to a blower mechanism and a push mechanism. The blower mechanism and the push mechanism are respectively located on both sides of the heat dissipation fin 3 and the heat dissipation port 401, and the output end of the push mechanism matches the heat dissipation fin 3.
[0026] The screening tool for short-board cells of an energy storage system in the present invention is similar in structure to the screening tool for short-board cells of an existing energy storage system, such as a BMS battery management device disclosed in the patent with announcement number CN214775478U. Figures 1 to 6 As shown, when the screening tool for short-board batteries of the energy storage system in the present invention monitors and screens short-board batteries of the energy storage system through the battery management body 1, the heat generated by the various components on the circuit board inside the battery management body 1 can be conducted to the outside of the battery management body 1 through the heat dissipation fins 3, and then the heat on the heat dissipation fins 3 is blown away by the blower mechanism, thereby achieving the purpose of cooling; and because the heat dissipation fins 3 completely block the installation opening 101 between the battery management body 1, dust in the external environment cannot enter the interior of the battery management body 1, and after the external dust adheres to the heat dissipation fins 3, the adhered dust or lint can be regularly cleaned by the pushing mechanism, which is convenient and easy to operate.
[0027] like Figure 6 As shown, an air inlet 402 is formed through the side wall of one end of the processing box 4, and the air inlet 402 matches the hair dryer structure.
[0028] More specifically, by providing the air inlet 402 , when the blower mechanism is started, air can be directly drawn in from the outside of the processing box 4 , thereby facilitating cooling of the surface of the heat dissipation fins 3 .
[0029] like Figure 4 and Figure 6 As shown, the hair drying mechanism includes a cross bracket 14, a support frame 11 and a power mechanism. One end of the support frame 11 is fixedly connected to the inner wall of the processing box 4, the inner wall of the support frame 11 is connected to the interior of the air inlet 402, the four ends of the cross bracket 14 are fixedly connected to the inner wall of the support frame 11, and the middle part of the cross bracket 14 is connected to the power mechanism.
[0030] More specifically, when it is necessary to blow air to cool the surface of the heat sink fins 3, it is only necessary to turn on the power mechanism, which can inhale air from the air inlet 402 and blow the wind toward the surface of the heat sink fins 3, and then discharge it to the outside of the processing box 4 from the heat dissipation port 401 below the heat sink fins 3.
[0031] like Figure 4 and Figure 6 As shown, the power mechanism includes a heat dissipation motor 13 and a fan blade 10 . The outer wall of the heat dissipation motor 13 is fixedly connected to the middle of the cross bracket 14 , and the output shaft of the heat dissipation motor 13 is fixedly connected to the central axis of the fan blade 10 .
[0032] More specifically, when the surface of the heat dissipation fin 3 needs to be cooled, the heat dissipation motor 13 only needs to be turned on. After the heat dissipation motor 13 is started, the output shaft can drive the fan blades 10 to rotate, and after the fan blades 10 rotate, wind force can be generated, thereby blowing this wind force to the surface of the heat dissipation fin 3 for cooling.
[0033] like Figure 6 As shown, a protective net 15 is threadedly connected to the inner wall of the air inlet 402 away from the support frame 11 .
[0034] More specifically, by providing the protective net 15 , it is possible to prevent debris in the external environment from hitting or damaging the heat dissipation motor 13 and the fan blades 10 located in the air inlet 402 and the support frame 11 .
[0035] like Figure 4 As shown, the pushing mechanism includes an electric push rod 7, a support rod 8 and a cleaning assembly. The outer wall of the electric push rod 7 is fixedly connected to the inner wall of the processing box 4, the output end of the electric push rod 7 is fixedly connected to one end of the support rod 8, and the other end of the support rod 8 is connected to the cleaning assembly. The outer wall of the cleaning assembly matches the heat dissipation fin 3.
[0036] More specifically, when it is necessary to clean the gaps between adjacent fins of the heat dissipation fins 3, it is only necessary to turn on the electric push rod 7. After the electric push rod 7 is started, the support rod 8 will be pushed outward. While the support rod 8 extends outward, it will push the cleaning component to move, and during the movement, the gaps in the heat dissipation fins 3 will be cleaned, thereby avoiding the adhesion of dust or lint, thereby reducing the impact on the heat dissipation fins 3.
[0037] like Figure 3-Figure 5 As shown, the cleaning assembly includes a connecting plate 6, several support strips 9 and several sponge strips 12. The upper surface of the connecting plate 6 is fixedly connected to the lower ends of the several support strips 9, and the sides of the several support strips 9 close to the heat dissipating fins 3 are respectively fixedly connected to the sides of the several sponge strips 12. The outer walls of the several sponge strips 12 are respectively slidably connected to the gaps of the heat dissipating fins 3. One of the support strips 9 is fixedly connected to the side away from the sponge strip 12 and the end of the support rod 8 away from the electric push rod 7.
[0038] More specifically, when the electric push rod 7 is started, the output end pushes the support bar 9 to move along the heat sink 3. While the support bar 9 moves inside the heat sink 3, it will scrape the gap surface of the heat sink 3 through the sponge bar 12, thereby scraping off the adhered dust or hair.
[0039] like Figure 1 、 Figure 3 and Figure 4 As shown, a plurality of mounting blocks 5 are fixedly connected to the outer wall of the processing box 4 , and the plurality of mounting blocks 5 are fastened to the battery management body 1 by bolts.
[0040] More specifically, by providing the mounting block 5 , it is possible to ensure a stable connection between the processing box 4 and the battery management body 1 , and to facilitate operation when the processing box 4 needs to be disassembled.
[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
