In addition, the mesh part 120 has mesh holes 121, which can allow the flames inside the energy storage container to pass through in the event of a fire, preventing the pressure inside the energy storage container from further increasing due to the accumulation of flames and causing an explosion, thus enabling the explosion-proof plate 118 to function effectively.

[0067] The following first combines Figures 1 to 3 The structure of the container body 100 of the energy storage container is described.

[0068] The container 100 also includes a base frame 130, corner posts 131, side wall panels 132, end wall panels 133, and a door 140. The top frame 110 is positioned above the base frame 130 along the height direction D1 of the energy storage container. The corner posts 131 extend along the height direction D1 of the energy storage container, with the top of the corner posts 131 connected to the top frame 110 and the bottom of the corner posts 131 connected to the base frame 130, thereby forming the main frame structure of the container 100.

[0069] The top frame 110 also includes two top side beams 111, two top top beams 112, four top corner pieces 124, multiple top crossbeams 113, and multiple top plates 114. The two top side beams 111 extend along the length direction D2 of the energy storage container and are spaced apart along the width direction D3 of the energy storage container. The two top top beams 112 are respectively located at both ends of the top side beams 111, and the top top beams 112 extend along the width direction D3 of the energy storage container. The four top corner pieces 124 are respectively located at both ends of the two top side beams 111, and the ends of the top side beams 111 and the bottom side beams are both connected to the top corner pieces 124. The top crossbeams 113 extend along the width direction D3 of the energy storage container, are located between the two top side beams 111, and the ends of the top crossbeams 113 are connected to the top side beams 111. The multiple top crossbeams 113 are spaced apart along the length direction D2 of the energy storage container. The top plate 114 is constructed as a corrugated plate, and multiple top plates 114 are arranged between the top crossbeams 113 and between the top crossbeams 113 and the top beam 112. The top plate 114 is connected to the top side beam 111, the top crossbeam 113 and the top beam 112, so the top plate 114 and the explosion-proof plate 118 achieve the enclosure of the top of the enclosure 100.

[0070] Side wall panels 132 are located on both sides of the container body 100. The top edge of the side wall panel 132 is connected to the top side beam 111, and the bottom edge of the side wall panel 132 is connected to the base frame 130. The side edge of the side wall panel 132 located at the end of the container body 100 is connected to the corner post 131. End wall panels 133 are located at the end of the container body 100.

Container doors 140 are located on the side or end of the container body 100 according to the actual project requirements of the energy storage container. For example... Figure 3 and Figure 6 As shown, the enclosure 100 is provided with doors 140 at both ends and sides for opening and closing, thereby facilitating the installation and maintenance of the battery pack 160 and electrical equipment 190. The side wall panels 132, end wall panels 133, and doors 140 surround and enclose the enclosure 100. Combined with the top frame 110 and bottom frame 130, the enclosure 100 is constructed to form an internal space for accommodating the battery pack 160 and electrical equipment 190.

[0071] Specifically, the explosion-proof plate 118 is installed on the top frame 110.

[0072] Reference Figure 1 Explosion-proof plates 118 are disposed between the top crossbeams 113, and the explosion-proof plates 118 and the top plate 114 are respectively disposed on both sides of the top crossbeams 113 along the length direction D2 of the energy storage container. Correspondingly, combined with Figure 2 As shown, the fixed frame 115 is positioned between and connected to the top crossbeam 113 to facilitate the installation of the explosion-proof plate 118. The use of the fixed frame 115 for installing the explosion-proof plate 118 provides high structural strength and ensures the stability of the explosion-proof plate 118 under normal use and pressure.

[0073] Optionally, combined Figure 3 As shown, the fixed frame 115 is higher than the top plate 114 along the height direction D1, which can prevent water from accumulating on the explosion-proof plate 118, thereby reducing the top-view damage of rainwater to the explosion-proof plate 118, which helps to extend the service life of the explosion-proof plate 118 and ensure the performance of the explosion-proof plate 118.

[0074] Optionally, combined Figure 4As shown, the fixed frame 115 includes four mounting tubes 116, which are arranged along the rectangular side and welded together. Blind hole nuts 117 are provided inside each mounting tube 116, and a first mounting hole corresponding to the blind hole nut 117 is provided on the top surface of each mounting tube 116. The explosion-proof plate 118 is fixed to the fixed frame 115 by fasteners 191 engaging with the first mounting hole and the blind hole nut 117. The arrangement of the fixed frame 115 and the explosion-proof plate 118, due to the explosion-proof plate 118 covering the connection points of the fixed frame 115 and the blind hole nuts 117, helps prevent rainwater from entering the mounting tubes 116 of the fixed frame 115, thereby reducing corrosion of the fixed frame 115 and ensuring the supporting performance of the fixed frame 115 for the explosion-proof plate 118.

[0075] Optionally, refer to Figure 6 The mounting plate 119 also includes a reinforcing beam 123, which is connected to the top surface of the mesh portion 120 and to the side wall of the connecting portion 122, thereby enhancing the overall structural strength of the mounting plate 119 and improving its load-bearing capacity and stability.

[0076] Optionally, refer to Figure 2 Multiple mesh openings 121 are evenly arranged on the mesh portion 120, which facilitates the fixing of pipelines to different positions on the mounting plate 119 and makes installation convenient. The pipelines can be fixed to the mesh portion 120 of the mounting plate 119 by ropes, cable ties or other components, or by fasteners 191 or other fasteners.

[0077] Overall, combined Figure 4 As shown, the mounting plate 119 includes a mesh portion 120 and four connecting portions 122. The mesh portion 120 is rectangular plate-shaped, and the four connecting portions 122 are respectively connected to the four sides of the mesh portion 120. The four connecting portions 122 extend to the inner sidewalls of the fixing frame 115 and are connected to the fixing frame 115, making the connection between the mounting plate 119 and the fixing frame 115 more stable.

[0078] Reference Figure 3 and Figure 5The energy storage container according to this utility model also includes an air conditioning component 150 (153), which includes a fixing member 151, an extension frame 152, and an air conditioner 153. Optionally, the fixing member 151 can be configured as a nut and is disposed inside the door 140. The extension frame 152 is connected to the fixing member 151 by a fastener 191, thereby fixing the extension frame 152 to the door 140. The extension frame 152 is rectangular, and the air conditioner 153 passes through the extension frame 152 and is connected to the extension frame 152 by the fastener 191, thereby fixing the air conditioner 153 to the door 140. The air conditioning component 150 enables the detachable installation of the air conditioner 153 and the door 140, facilitating installation and debugging.

[0079] Reference Figure 3 and Figure 5 The container door 140 is provided with a connection port 141 for connecting to the interior of the container body 100 of the energy storage container. The air conditioner 153 is provided with an air outlet on the side near the container door 140. When the air conditioner 153 is installed on the container door 140 through the extension frame 152, the air outlet of the air conditioner 153 is connected to the connection port 141, so that the air conditioner 153 can heat or cool the interior of the container body 100 when it is working, thereby controlling the temperature inside the container body 100 of the energy storage container.

[0080] Optionally, the air conditioning 153 assembly 150 also includes a sealing gasket disposed between the extension frame 152 and the door 140, thereby sealing the connection between the extension frame 152 and the outer wall of the door 140, reducing temperature loss inside and outside the housing 100, and improving the energy efficiency of the air conditioning 153.

[0081] Optionally, the air conditioning 153 assembly 150 also includes a deflector 154, which is disposed within the connection port 141. The deflector 154 and the connection port 141 form a flow channel extending toward the top of the equipment 190 inside the container 100 of the energy storage container. This prevents the cold air from the air conditioning 153 from blowing directly onto the equipment 190 inside the container 100, thus avoiding localized low temperatures and condensation on the equipment 190. Instead, the cold air from the air conditioning 153 can be evenly blown into the container 100 through the flow channel, resulting in a uniform temperature distribution inside the container 100 and preventing damage to the equipment 190 due to localized overcooling.

[0082] Optionally, a connecting piece 155 is provided on the side of the guide plate 154. The connecting piece 155 is connected to the inner wall of the communication port 141 by a fastener 191, thereby realizing the fixed installation of the guide plate 154.

[0083] Optionally, the top of the deflector plate 154 is close to the inside of the door 140, and the bottom of the deflector plate 154 is close to the outside of the door 140, so that the airflow generated by the air conditioner 153 flows to the top of the cabinet 100 under the guidance of the deflector plate 154, so that the gas is evenly blown into the cabinet 100.

[0084] Reference Figure 6 The energy storage container according to this utility model also includes a battery pack 160, multiple columns 170, and multiple fixed guide rails 180. The columns 170 extend along the height direction D1 of the energy storage container and are installed inside the container body 100. Specifically, combined with... Figure 3 As shown, the top of the column 170 is connected to the top crossbeam 113, and the bottom of the column 170 is connected to the base frame 130, thus providing installation support points for the fixed guide rail 180. Multiple columns 170 are arranged at intervals along the length direction D2 and the width direction D3 of the energy storage container, while the fixed guide rail 180 extends along the width direction D3 of the energy storage container and connects to the multiple columns 170 arranged at intervals along the width direction D3, and the fixed guide rail 180 is arranged at intervals along the height direction D1. Through the arrangement of the columns 170 and the fixed guide rail 180, multiple accommodating spaces for installing the battery pack 160 are formed within the container 100. The fixed guide rail 180 can effectively support the battery pack 160 on both sides, making the installation of the battery pack 160 more stable.

[0085] Combination Figure 7 As shown, the fixed guide rail 180 includes a support beam 181, which extends along the width direction D3 of the energy storage container and is connected to the column 170. The first end of the support beam 181 has a bent edge 182, and the second end has a second mounting hole 183. The bent edge 182 extends along the height direction D1 and has a positioning hole 184 with a protruding structure that mates with the battery pack 160. Figure 9 As shown, for one side of the battery pack 160, a positioning post 161 is provided at one end of the battery pack 160, and a third mounting hole 162 is provided at the other end of the battery pack 160. When the battery pack 160 is placed on the fixed guide rail 180, the positioning post 161 of the battery pack 160 passes through the positioning hole 184 of the bent edge 182, and then fasteners 191 are sequentially passed through the third mounting hole 162 of the battery pack 160 and the second mounting hole 183 of the support beam 181, thereby fixing the battery pack 160 to the support beam 181, and the support beam 181 can also effectively support the battery pack 160. In addition, the positioning hole 184 can be a slotted hole, so as to perform preliminary positioning for the installation of the battery pack 160, which facilitates the installation.

[0086] Optionally, combined Figure 7 and Figure 8As shown, the fixed guide rail 180 also includes a connector 185, which is connected to the bottom of the support beam 181. The connector 185 is provided with a riveting hole 188, and is riveted to the column 170 by rivets 192, further securing the support beam 181 to the column 170 and enhancing the connection strength and stability of the fixed guide rail 180. The side of the support beam 181 is provided with a fourth mounting hole 187, used to connect to the column 170 via fasteners 191, achieving initial installation of the fixed guide rail 180. Then, the connector 185 and the column 170 are riveted together, facilitating installation.

[0087] Optionally, the fixed guide rail 180 also includes a guide member 186, which is connected to the support beam 181 and spaced apart from the bottom wall of the support beam 181, thereby allowing the edge of the base of the battery pack 160 to pass through. The guide member 186 ensures that the battery pack 160 can smoothly and accurately enter the mounting position on the fixed guide rail 180, and also provides effective lateral restraint on the battery pack 160 after it is installed in place, preventing unnecessary displacement or shaking of the battery pack 160 during transportation or use.

[0088] In addition, the fixed guide rail 180 includes at least three guide members 186, which are arranged at intervals along the extension direction of the fixed guide rail 180, so that the battery pack 160 is continuously guided during installation, thereby improving installation accuracy.

[0089] In summary, the battery pack 160 and the fixed guide rail 180 are connected by the cooperation of the positioning pin 161 and positioning hole 184, the cooperation of the second mounting hole 183 and the third mounting hole 162, and the guidance of the guide member 186, forming a multi-point fixing effect arranged along the extension direction of the fixed guide rail 180. This greatly improves the stability, reliability and overall structural safety of the battery pack 160 installation, and effectively ensures the stable operation of the battery pack 160 under various working conditions.
