Description

Technical Field

[0001] The utility model relates to the technical field of containers, and in particular to a marine energy storage container. Background Art

[0002] If a battery pack spontaneously combusts inside a container on a ship or offshore platform, the situation for personnel is even more dangerous than on land due to space and geographical constraints. Therefore, marine energy storage containers require strict fire protection, heat dissipation, and ventilation structures. Furthermore, existing marine energy storage containers, equipped with protruding components such as exhaust fans, are typically larger than standard container dimensions. This makes them inconvenient for battery swapping and unable to meet international standard container shipping requirements.

[0003] Therefore, a marine energy storage container is needed to at least partially solve the above problems. Utility Model Content

[0099] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in this document are for illustrative purposes only and are not limiting.

[0100] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0101] like Figures 1 to 15As shown, the utility model provides a marine energy storage container 100, comprising a box body 110, a partition 111, an equipment compartment 112, a battery compartment 113 and a first exhaust fan 153. The partition 111 is arranged along the width direction of the marine energy storage container 100. The interior of the box body is divided by the partition 111 into an equipment compartment 112 and a battery compartment 113 arranged along the length direction of the marine energy storage container. The equipment compartment 112 is used to place electrical equipment 131. The battery compartment 113 is used to store battery packs. The air inlet of the first exhaust fan 153 is connected to the interior of the battery compartment 113, and the air outlet of the first exhaust fan 153 is connected to the outside of the box body 110. The box body 110 is provided with a groove 115 recessed toward the interior of the box body for accommodating the first exhaust fan 153.

[0102] The marine energy storage container sets the first exhaust fan in a recessed groove of the container body that is recessed toward the interior of the container body, making it easy to install, maintain, and inspect the first exhaust fan from outside the container body, effectively reducing the frequency of opening the container body and further improving the sealing of the container body. At the same time, it can be constructed with the same external dimensions as the standard container body. The energy storage container can meet the convenience of "battery replacement" and meet the international standard container shipping requirements, so that the replaced container can be easily transferred. By setting a partition, an equipment compartment and a battery compartment that are independent of each other in the length direction of the container can be formed. When the battery pack in the battery compartment spontaneously combusts, the partition can be used to prevent the fire from spreading toward the equipment compartment. When a circuit fault in the equipment compartment causes a fire, the partition can be used to prevent the fire from spreading toward the battery compartment. This can help reduce safety hazards and improve the fireproof performance of marine energy storage containers.

[0103] It should be noted that, unless otherwise specified / limited, the terms "length direction," "width direction," "height direction," "interior," and "exterior" mentioned herein are all relative to the marine energy storage container. Shutters may be provided at the ends or on the sidewalls of the marine energy storage container.

[0104] refer to Figures 1 to 6 The marine energy storage container 100 may include a housing 110, at least two doors 123, a partition 111, electrical equipment 131, a liquid cooling unit 145, a first ventilation port 141, a cold fluid pipeline, a first exhaust fan 153, a second air intake fan 154, and a shutter 155. The at least two doors 123 are connected to the housing 110, and at least one of the at least two doors 123 is disposed at the rear end 119 to open the equipment compartment 112.

[0105] Partition 111 is arranged along the width of the marine energy storage container 100. The interior of the housing 110 is divided by partition 111 into an equipment compartment 112 and a battery compartment 113, which are arranged along the length of the marine energy storage container 100. Electrical equipment 131 is disposed within the equipment compartment 112. A liquid cooling unit 145 is disposed within the equipment compartment 112, opposite the electrical equipment 131 along the width. The liquid cooling unit 145 includes a heat exchanger and a first air intake fan. The air inlet 151 of the first air intake fan is disposed toward the electrical equipment 131, and the air outlet of the first air intake fan is connected to the inlet on the cold side of the heat exchanger. A first ventilation port 141 is disposed within the housing 110 and connected to the equipment compartment 112. The first ventilation port 141 is disposed closer to the electrical equipment 131 than the liquid cooling unit 145.

[0106] Thus, not only does the liquid cooling unit 145 improve the cooling efficiency of the battery compartment 113, but the air intake fan of the liquid cooling unit 145 itself also simultaneously achieves ventilation of the equipment compartment 112 and cooling of the liquid circulating from the battery compartment 113 back into the liquid cooling unit 145, simplifying the structure and reducing heat dissipation costs. Furthermore, by providing the partition 111, the equipment compartment 112 and the battery compartment 113 can be formed to be independent of each other in the longitudinal direction of the container. When the battery pack in the battery compartment 113 spontaneously combusts, the partition 111 can be used to prevent the fire from spreading toward the equipment compartment 112. Also, when a circuit fault in the equipment compartment 112 causes a fire, the partition 111 can be used to prevent the fire from spreading toward the battery compartment 113. This can help reduce safety hazards and improve the fire resistance of the marine energy storage container 100.

[0107] The box body 110 may include a first side wall 121 and a second side wall 122 arranged opposite to each other along the width direction, a front end 114 and a rear end 119 arranged opposite to each other along the length direction, a top assembly and a bottom assembly located at the top and bottom respectively along the height direction, and an internal skeleton assembly located inside the box body 110.

[0108] The internal skeleton assembly may include a partition 111. The partition 111 is arranged along the width direction of the marine energy storage container 100. The interior of the box body 110 is divided by the partition 111 into an equipment compartment 112 and a battery compartment 113 arranged along the length direction of the marine energy storage container 100. By providing the partition 111, an equipment compartment 112 and a battery compartment 113 that are independent of each other in the length direction of the container can be formed. When the battery pack in the battery compartment 113 spontaneously combusts, the partition 111 can be used to prevent the fire from spreading toward the equipment compartment 112; and when a circuit fault in the equipment compartment 112 causes a fire, the partition 111 can be used to prevent the fire from spreading toward the battery compartment 113. This can help reduce safety hazards and improve the fire resistance of the marine energy storage container 100.

[0109] In some embodiments, the partition 111 may be closer to the rear end 119 of the housing 110, and the device compartment 112 may be closer to the rear end 119 of the housing 110 than the battery compartment 113. This case will be used as an example for detailed description.

[0110] The battery pack can be arranged in the battery compartment 113. The cold fluid pipeline is connected to the inlet and outlet of the hot side of the heat exchanger of the liquid cooling unit in a circular manner and extends to the battery compartment 113 to cool the battery pack in the battery compartment 113. In other words, the cold fluid (i.e., liquid hereinafter) flows cyclically in the battery compartment 113 to cool the battery pack. The liquid after cooling the battery pack, that is, the liquid downstream of the battery pack, circulates back from the battery compartment 113 to the inlet of the hot side of the heat exchanger in the liquid cooling unit 145, and is cooled by the air entering from the inlet of the cold side of the heat exchanger in the liquid cooling unit 145 as described below. The cooled liquid flows out from the outlet of the hot side of the heat exchanger and flows into the battery compartment 113 again through the cold fluid pipeline.

[0111] refer to Figures 1 to 3 The electrical equipment 131 and the liquid cooling unit 145 are disposed within the equipment compartment 112. The liquid cooling unit 145 and the electrical equipment 131 are disposed opposite each other along the width direction. The electrical equipment 131 can be disposed adjacent to the first sidewall 121, and the liquid cooling unit 145 can be disposed adjacent to the second sidewall 122. The electrical equipment 131 and the liquid cooling unit 145 can be separated in the width direction by a passageway 146. The passageway 146 can correspond to a door 123 disposed at the rear end 119. This allows personnel to conveniently enter the equipment compartment 112 through the door 123 at the rear end 119 and move along the passageway 146 to conveniently inspect and maintain the liquid cooling unit 145 and / or the electrical equipment 131. The maintenance door of the electrical equipment 131 can face the liquid cooling unit 145, that is, both face the passageway 146, further facilitating personnel's movement along the passageway 146 to conveniently inspect and maintain the electrical equipment 131.

[0112] The aforementioned walk-in equipment compartment 112 design allows workers to open door 123 to enter the equipment compartment 112 for maintenance and inspection. This effectively reduces the frequency of opening the enclosure 110 and further improves the sealing of the enclosure 110. Even in rainy or snowy weather, workers performing maintenance inside the equipment compartment 112 do not need to worry about rainwater flowing into the enclosure 110 through the access door. Door 123 can be equipped with an escape lock to ensure that workers can escape while performing maintenance.

[0113] According to actual needs, the electrical equipment 131 may include a high-voltage box 132, a control cabinet 133, a power supply cabinet 134 and other equipment arranged in sequence from the inside to the outside along the length direction.

[0114] A fire extinguisher 135 may also be provided in the equipment compartment 112. The fire extinguisher 135 is provided along the width direction between the electrical equipment 131 and the liquid cooling unit 145, and the fire extinguisher 135 is provided at the partition 111. Thus, the equipment space is reasonably distributed, and the staff can conveniently use the fire extinguisher 135 to extinguish the fire when necessary.

[0115] Another door 123 may also be provided at the rear end 119. For example, a door 123 may be provided at a position corresponding to the liquid cooling unit 145 at the rear end 119 to facilitate inspection and maintenance of the liquid cooling unit 145 from outside the box, thereby improving safety.

[0116] The liquid cooling unit 145 includes a heat exchanger and a first air inlet fan. The air inlet 151 of the first air inlet fan is arranged toward the electrical equipment 131 , and the air outlet of the first air inlet fan is connected to the inlet of the cold side of the heat exchanger. The first ventilation port 141 is arranged close to the electrical equipment 131 relative to the liquid cooling unit 145, so that the air outside the box first reaches the electrical equipment 131 to cool and ventilate the electrical equipment 131, and then the air reaches the liquid cooling unit 145, specifically the air inlet 151 of the first air inlet fan of the liquid cooling unit 145. The first air inlet fan draws the air reaching the air inlet 151 of the first air inlet fan of the liquid cooling unit 145 into the inlet of the cold side of the heat exchanger in the liquid cooling unit 145 to cool the liquid circulated from the battery compartment 113 back to the liquid cooling unit 145, which simplifies the structure and reduces the heat dissipation cost; the air after liquid cooling flows out from the outlet on the cold side of the heat exchanger and is discharged to the outside of the box 110 through the first air duct 157 of the liquid cooling unit 145.

[0117] In some embodiments, the liquid cooling unit 145 may further include a second exhaust fan, the air inlet of the second exhaust fan being connected to the outlet of the cold side of the heat exchanger, and the air outlet of the second exhaust fan being connected to the outside of the cabinet 110. This improves the ventilation capacity of the liquid cooling unit 145 in the equipment compartment 112.

[0118] In summary, according to the marine energy storage container 100 of the present invention, not only the liquid cooling unit 145 is used to improve the cooling efficiency of the battery compartment 113, but also the air intake fan of the liquid cooling unit 145 itself is used to simultaneously realize the ventilation of the equipment compartment 112 and the cooling of the liquid circulated from the battery compartment 113 back to the liquid cooling unit 145, which simplifies the structure and reduces the heat dissipation cost, and there is no need for a special / additional fan for ventilation and cooling the equipment compartment 112.

[0119] The box body 110 can be constructed to have the same outer dimensions as the box body 110 of a standard container. With this design, the energy storage container can meet the convenience of "battery replacement" and meet the international standard container shipping requirements, so that the replaced container can be easily transferred.

[0120] The marine energy storage container 100 may further include a first exhaust fan 153. The air inlet of the first exhaust fan 153 is connected to the interior of the battery compartment 113, and the air outlet of the first exhaust fan 153 may be connected to the exterior of the housing 110 via a third air duct 159. Thus, the air in the battery compartment 113 is exhausted by the first exhaust fan 153, enhancing ventilation within the battery compartment 113 and providing explosion protection. The first exhaust fan 153 may be equipped with a damper to adjust the on / off state of the first exhaust fan 153, such as whether it is on, the degree of opening, or off.

[0121] refer to Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 The first exhaust fan 153 can be disposed in the housing 110, for example, at the front end 114 of the housing 110. Specifically, the front end 114 of the housing 110 can include a front end body 114a and a groove 115. The groove 115 is connected to the front end body 114a and is recessed into the front end body 114a along the length direction toward the interior of the housing 110, for accommodating the first exhaust fan 153. As a result, the first exhaust fan 153 can be disposed without protruding from the housing 110, and can specifically be a corner piece that does not protrude from the housing 110, facilitating the configuration of the housing 110 to have the same external dimensions as the housing 110 of a standard container.

[0122] Of course, if needed and / or desired, the first exhaust fan 153 may also be disposed at other locations of the box body 110 .

[0123] Specifically, the front body 114a may have a mounting opening that corresponds to a notch in the recess 115. The recess 115 may include a back panel 115a extending along the height of the marine energy storage container 100, an upper connecting plate 115b and a lower connecting plate 115c that connect the back panel 115a to the front body 114a, and two side connecting plates 115d that connect the back panel 115a to the front body 114a. The upper connecting plate 115b and the lower connecting plate 115c may be arranged opposite each other along the height. The upper connecting plate 115b may have an opening that corresponds to the air inlet of the first exhaust fan 153. It is understood that air and / or fire extinguishing gas within the battery compartment 113 can enter the first exhaust fan 153 through its air inlet and exit the housing 110 through its exhaust port. The lower connecting plate 115c may extend outward and downward along the length direction, so that rainwater entering from the outside can quickly flow out of the groove 115 to prevent accumulation.

[0124] The two side connecting plates 115d can be arranged opposite to each other along the width direction, and each of the two side connecting plates 115d has a flange 115e facing the outside of the groove 115, and the flange 115e is connected to the side of the front body 114a facing the inside of the box body 110 along the length direction. As a result, the structure is simple and the connection is stable.

[0125] A maintenance cover 117 and a mesh plate 118 can be provided at the installation port. The maintenance cover 117 and the mesh plate 118 can both be connected to the front end body 114a. This makes it convenient for staff outside the box 110 to open the maintenance cover 117 to install, inspect, maintain, open and close the first exhaust fan 153, etc., which can effectively reduce the frequency of opening the box 110 and further improve the sealing of the box 110. The maintenance cover 117 and the mesh plate 118 can be arranged in the height direction, and the position of the mesh plate 118 can correspond to the position of the exhaust port of the first exhaust fan 153. In this way, external foreign matter and the like can be prevented from entering the first exhaust fan 153.

[0126] In some embodiments, the groove 115 may be a sheet metal groove 115 to increase the strength of the groove 115 .

[0127] refer to Figure 1 、 Figure 2 、 Figure 4 as well as Figure 6 The marine energy storage container 100 may further include a second air intake fan 154, which may be disposed within the equipment compartment 112. Thus, the second air intake fan 154 does not protrude from the container body 110, facilitating the configuration of the container body 110 with the same dimensions as a standard container. Furthermore, the placement of the second air intake fan 154 within the equipment compartment 112 facilitates maintenance operations such as opening and closing the first exhaust fan 153 while personnel are within the equipment compartment 112, effectively avoiding maintenance risks in harsh climates and improving maintainability.

[0128] The air inlet of the second air inlet fan 154 can be connected to the outside of the box body 110, and the air outlet of the second air inlet fan 154 can be connected to the battery compartment 113. Thus, air can be introduced into the equipment compartment 112 through the second air inlet fan 154.

[0129] In some embodiments, as Figure 1 、 Figure 2 and Figure 6As shown, the second air inlet fan 154 can be connected to the outside of the box body 110 via the second air duct 158, and a wind damper 154a is provided at the air outlet of the second air inlet fan 154 to adjust the opening and closing state of the second air inlet fan 154, such as the opening or opening degree, closing and other states of the second air inlet fan 154, so as to adjust the state of gas such as air entering the battery compartment 113 through the second air inlet fan 154 or flowing out of the battery compartment 113 through the second air inlet fan 154.

[0130] When the gas pressure in the box exceeds the set value detected by a pressure detector or pressure sensor, the damper 154a of the second air inlet fan 154 can be slightly opened, so that the gas in the battery compartment 113 can flow out from the air inlet of the second air inlet fan 154 and its corresponding second ventilation port 142 and be released outside the box body 110.

[0131] As can be seen in the illustrated embodiment, the second air duct 158 can be a longer pipe, so that the gas in the battery compartment 113 is discharged from the air inlet of the second air inlet fan 154 and then gradually cooled in the second air duct 158 to reduce the temperature before being discharged from the second ventilation port 142, thereby reducing the temperature of the gas discharged from the box. The high-temperature gas is controlled inside the box through the in-box pressure relief technology, and the gas is slowly released to the outside of the box 110, preventing the high-temperature gas from directly spraying out of the box, thereby reducing the risk of explosion and the risk of injury caused by high-temperature gas.

[0132] In the illustrated embodiment, the housing 110 may include a first sidewall 121 and a second sidewall 122 disposed opposite each other along the width direction, and a front end 114 and a rear end 119 disposed opposite each other along the length direction. The electrical equipment 131 may be disposed proximate to the first sidewall 121, and the liquid cooling unit 145 may be disposed proximate to the second sidewall 122. A first ventilation port 141 may be provided on the first sidewall 121. A second ventilation port 142, a third ventilation port 143, and a fourth ventilation port 144 may be disposed sequentially along the width direction at the upper portion of the rear end 119. The second ventilation port 142 is closer to the electrical equipment 131 than the third ventilation port 143, i.e., the second ventilation port 142 is closer to the first sidewall 121 than the third ventilation port 143 and the fourth ventilation port 144. The fourth ventilation port 144 is closer to the liquid cooling unit 145 than the third ventilation port 143, i.e., the fourth ventilation port 144 is closer to the second sidewall 122 than the second ventilation port 142 and the third ventilation port 143. The second ventilation port 142 can be connected to the second air duct 158 so that air flows from the second air duct 158 into the first air inlet and then into the battery compartment 113, or the air leaked from the battery compartment 113 flows from the first air inlet into the second air duct 158 and then out of the battery compartment 113 from the second ventilation port 142. The fourth ventilation port 144 can be connected to the first air duct 157 of the liquid cooling unit 145 to discharge the air flowing out of the outlet on the cold side of the heat exchanger. The third ventilation port 143 is connected to the inside of the equipment compartment 112 and can serve as a supplement to the first ventilation port 141 to allow air outside the box to enter the equipment compartment 112, or it can allow air to leak from the equipment compartment 112 when the gas pressure in the equipment compartment 112 is too high. Of course, if necessary and / or desired, the third ventilation port 143 can also be omitted.

[0133] refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 11 and Figure 12 Optionally, the first ventilation port 141 may be equipped with a louver 155. The louver 155 may include a window frame and a plurality of blades 156. The plurality of blades 156 may be horizontally connected to the window frame. The blades 156 have a special shape and may include at least two vertical segments 156a, at least one connecting segment 156b, and at least one branch segment 156c.

[0134] The following describes in detail the blades 156 of the louver 155 installed in the first ventilation port 141 provided on the first sidewall 121. The blades 156 may include at least two vertical segments 156a, at least one connecting segment 156b, and at least one branch segment 156c. The at least two vertical segments 156a are spaced apart in the height direction, and the at least two vertical segments 156a are spaced apart in the width direction. The connecting segment 156b connects two adjacent vertical segments 156a. The branch segment 156c includes a first end and a second end disposed oppositely in the width direction. The first end of the branch segment 156c is connected to the vertical segment 156a, and the second end of the branch segment 156c is disconnected from the vertical segment 156a. The vertical section 156a and the connecting section 156b can prevent rainwater from entering the interior of the housing 110 from outside the housing 110. The connecting section 156b and the branch section 156c can guide rainwater downward, further preventing rainwater from entering the interior of the housing 110 from outside the housing 110. The vertical section 156a and the connecting section 156b can also prevent flames and embers from flying from inside the housing 110 to the outside of the housing 110, thereby reducing the temperature. The connecting section 156b and the branch section 156c can guide embers downward, further preventing the interior of the housing 110 from flying outside the housing 110. The structure of the louver 155 can achieve waterproof and breathable properties.

[0135] In some embodiments, a first end of the branch segment 156 c may be connected to an upper end of the vertical segment 156 a , and a second end of the branch segment 156 c may extend outward and downward in the width direction.

[0136] In some embodiments, a first end of the branch segment 156 c may be connected to a lower end of the vertical segment 156 a , and a second end of the branch segment 156 c may extend inward and downward along the width direction.

[0137] In a second embodiment (not shown), a first ventilation port 141, a second ventilation port 142, and a fourth ventilation port 144 may be sequentially provided along the width direction at the upper portion of the rear end 119. The first ventilation port 141 is closer to the electrical equipment 131 than the second ventilation port 142, that is, the first ventilation port 141 is closer to the first sidewall 121 than the second ventilation port 142 and the fourth ventilation port 144. The fourth ventilation port 144 is closer to the liquid cooling unit 145 than the second ventilation port 142, that is, the fourth ventilation port 144 is closer to the second sidewall 122 than the second ventilation port 142 and the first ventilation port 141. The fourth ventilation port 144 may be connected to the first air duct 157 of the liquid cooling unit 145 to exhaust air flowing out of the outlet on the cold side of the heat exchanger. The second ventilation port 142 can be connected to the second air duct 158 so that air flows from the second air duct 158 into the first air inlet and then into the battery compartment 113, or so that air released from the battery compartment 113 flows from the first air inlet into the second air duct 158 and then out of the battery compartment 113 through the second ventilation port 142. Of course, if needed and / or desired, the first ventilation port 141 can also be provided on the first side wall 121 near the electrical device 131 to cooperate with the first ventilation port 141 provided on the rear end 119.

[0138] It can be understood that in the above-mentioned embodiment not shown in the figure, the second air duct 158 extends from the second air inlet fan 154 to the second ventilation port 142. The second air duct 158 is longer than the length of the illustrated embodiment, which further enables the gas in the battery compartment 113 to be discharged from the air inlet of the second air inlet fan 154 and then gradually cooled in the second air duct 158 to reduce the temperature before being discharged from the second ventilation port 142, thereby minimizing the temperature of the gas discharged from the box. The high-temperature gas is controlled inside the box through the pressure relief technology inside the box, and the gas is slowly released to the outside of the box 110, preventing the high-temperature gas from directly spraying out of the box, thereby reducing the risk of explosion and the risk of injury caused by high-temperature gas.

[0139] In the specific embodiment shown in the drawings, the blade 156 includes three vertical sections 156a, two connecting sections 156b and four branch sections 156c. The three vertical sections 156a include an upper vertical section 156a, a middle vertical section 156a and a lower vertical section 156a along the height direction. The upper end of the upper vertical section 156a is connected to a branch section 156c extending outward and downward, the upper end of the middle vertical section 156a is connected to a branch section 156c extending outward and downward, the lower end of the middle vertical section 156a is connected to a branch section 156c extending inward and downward, and the lower end of the lower vertical section 156a is connected to a branch section 156c extending inward and downward.

[0140] In another embodiment (not shown), the structure of the blades 156 of the louver 155 installed in the first ventilation port 141 provided at the rear end 119 is similar to the structure of the blades 156 of the louver 155 installed in the first ventilation port 141 provided at the first sidewall 121 in the first embodiment, except that the vertical sections 156a, connecting sections 156b, and branch sections 156c of the blades 156 are arranged in different directions due to the installation position. Therefore, elements having substantially the same functions as those in the first embodiment are numbered the same herein.

[0141] Specifically, the first ventilation port 141 may be equipped with a louver 155, which may include a window frame and a plurality of blades 156. The blades 156 may include at least two vertical segments 156a, at least one connecting segment 156b, and at least one branch segment 156c. The at least two vertical segments 156a are spaced apart in the height direction, and the at least two vertical segments 156a are spaced apart in the length direction. The connecting segment 156b connects two adjacent vertical segments 156a. The branch segment 156c includes a first end and a second end disposed opposite to each other in the length direction. The first end is connected to the vertical segment 156a, and the second end is disconnected from the vertical segment 156a.

[0142] In some embodiments, a first end of the branch segment 156 c is connected to the upper end of the vertical segment 156 a , and a second end of the branch segment 156 c extends outward and downward along the length direction.

[0143] In some embodiments, a first end of the branch segment 156 c is connected to the lower end of the vertical segment 156 a , and a second end of the branch segment 156 c extends inward and downward along the length direction.

[0144] A louver 155 may also be installed at the third ventilation port 143 , and the louver 155 may have the same structure as the louver 155 installed at the first ventilation port 141 .

[0145] A louver 155 may also be installed at the second ventilation port 142 . The louver 155 may have the same structure as or different from the louver 155 installed at the first ventilation port 141 .

[0146] A louver 155 may also be installed at the fourth ventilation port 144 . The louver 155 may have the same structure as or different from the louver 155 installed at the first ventilation port 141 .

[0147] refer to Figures 13 to 15 The marine energy storage container 100 may further include a receiving box 160, which is mounted to the box body 110 so that the receiving box 160 does not protrude from the box body 110. Specifically, the receiving box 160 may be a corner piece that does not protrude from the box body 110, so that the box body 110 is constructed to have the same external dimensions as the box body 110 of a standard container.

[0148] When the storage box cover 163 is covered on the storage box body 162, it is flush with the outside of the box body 110 or recessed into the box body 110 toward the inside of the box body 110. In this way, the storage box 160 can be arranged without protruding from the box body 110.

[0149] The storage box 160 may include a stepped portion 161, a storage box body 162, a sealing frame 165, and a storage box cover 163. The stepped portion 161 is recessed into the housing 110 toward the interior of the housing 110. The stepped portion 161 includes an upper edge 161a and a lower edge 161b disposed oppositely in the height direction, and two side edges 161c disposed oppositely in the width direction. The storage box body 162 is recessed into the stepped portion 161 toward the interior of the housing 110 to define a storage space. The storage box body 162 is connected to the stepped portion 161. The sealing frame 165 may protrude from the stepped portion 161 toward the exterior of the housing 110. The storage box cover 163 may include a flat portion 163a and a flanged portion 163b. The flanged portion 163b is connected to the periphery of the flat portion 163a and extends from the flat portion 163a toward the interior of the housing 110, so that the storage box cover 163 is covered by the sealing frame 165. This improves the waterproof performance of the storage box 160.

[0150] In some embodiments, the storage box cover 163 can be pivotally connected to the upper edge 161a or the lower edge 161b of the step portion 161 to move between a closed position and an open position, thereby allowing the storage box cover 163 to flip upward to open or flip downward to open from the closed position.

[0151] In some other embodiments, the storage box cover 163 can be pivotally connected to one of the two side edges 161c of the step portion 161 to move between a closed position and an open position, thereby allowing the storage box cover 163 to be pivotally opened or closed.

[0152] In some embodiments, the container lid 163 can be pivotally connected to the upper edge 161a of the step portion 161, thereby allowing the container lid 163 to be flipped upward from a closed position to open. The container 160 can also include at least one retractable support member 164, with the two ends of the retractable support member 164, which are arranged oppositely in the height direction, being retractably supported between the container lid 163 and one of the lower portions of the lower edge 161b and the two side edges 161c of the container 160. This allows the container lid 163 to be reliably supported by the retractable support member 164 after the staff flips it upward to open it, and will not immediately return to the closed position due to gravity. The container lid 163 is in a normally closed state under the action of gravity, which can protect the internal components from being wetted by rain.

[0153] In some embodiments, the retractable support member 164 may include a sleeve 164a, a sleeve rod 164b, and a spring. The sleeve 164a defines a cavity extending along its length. The lower end of the sleeve 164a is pivotally connected to the lower edge 161b of the container 160 and one of the lower portions of the two side edges 161c. The sleeve rod 164b is slidably disposed within the sleeve 164a, extending within the cavity of the sleeve 164a. The upper end of the sleeve rod 164b is movably connected to the container lid 163. The lower end of the spring is fixed to the bottom wall of the sleeve 164a, and the upper end of the spring is connected to the lower end of the sleeve rod 164b. This allows for simple and reliable support of the container lid 163 by utilizing elastic potential energy. Consequently, the retractable support member 164 provides excellent support, cushioning, and braking effects, enabling flexible and precise start and stop control of the container lid 163 at any angle.

[0154] The accommodating box cover 163 and the retractable support member 164 may be connected via a limiting member 167 to ensure that the retractable support member 164 can move around the accommodating box cover 163 along a certain trajectory.

[0155] like Figure 13 and Figure 14 The storage box 160 may be an electrical box. An electrical interface is provided in the storage space of the storage box 160. The electrical interface is electrically connected to the electrical device 131 to control the start and stop of the electrical device 131. The storage box cover 163 can be opened toward the outside of the box body 110, making it easier for workers to open the electrical box from outside the box body 110.

[0156] like Figure 13 、 Figure 14 as well as Figure 15 As shown, the storage box 160 can be used as a tool box to store, for example, maintenance tools, etc. The storage box cover 163 can be opened toward the outside of the box body 110, so as to facilitate the staff to open the tool box from the outside of the box body 110.

[0157] The receiving box 160 may also be used as an antenna storage box.

[0158] A plurality of drainage holes 166 may be provided at intervals at the bottom of the receiving box body 162 and corresponding positions of the receiving box cover 163 to prevent water accumulation.

[0159] The housing 110 may be provided with at least one external grounding member corresponding to the device compartment 112 and the battery compartment 113. For example, the external grounding member may be an external grounding busbar. At least one internal grounding member may be provided inside the device compartment 112 and the battery compartment 113. The internal grounding member may be provided on the bottom assembly and may be, for example, an internal grounding busbar.

[0160] The marine energy storage container 100 may also include firefighting equipment, such as a firefighting gas tank, to extinguish fires in the event of a fire. Firefighting piping may be connected to the firefighting equipment and extend to the battery compartment 113. Firefighting nozzles are provided at intervals along the firefighting piping to spray firefighting gas toward the battery compartment 113 and the equipment compartment 112.

[0161] The equipment compartment 112 and the battery compartment 113 may be equipped with at least one of a smoke sensor, a temperature sensor, a dehumidifier, and a camera. These devices are electronically controlled devices. The smoke sensor detects smoke inside the enclosure 110 and feeds the detected smoke signal back to, for example, a control system. The temperature sensor detects the temperature inside the enclosure 110 and feeds the detected temperature signal back to the control system. The dehumidifier dehumidifies the equipment compartment 112 and the battery compartment 113 to ensure dry air inside. The camera monitors the conditions inside the enclosure in real time.

[0162] The container's firefighting system consists of firefighting equipment, firefighting pipes, firefighting nozzles, smoke sensors, temperature sensors, and other related components. When the temperature inside the container rises to an abnormal level, the temperature sensor detects the abnormal temperature and feeds the temperature signal back to the control system, which issues an alarm. When the smoke sensor detects smoke and feeds the smoke signal back to the control system, the control system activates the firefighting equipment, spraying fire-extinguishing gas such as HFC-227ea through the firefighting nozzles on the top.

[0163] The present invention uses a liquid cooling unit 145 to cool the battery compartment 113. Under normal circumstances, the first air inlet fan is always open, and the second air inlet fan 154, the damper 154a of the second air inlet fan 154, the first exhaust fan 153, and the damper of the first exhaust fan 153 are always closed. When a pressure detector or pressure sensor detects that the gas pressure in the box exceeds a set value, the damper 154a of the second air inlet fan 154 can be slightly opened, allowing the gas in the battery compartment 113 to flow out from the air inlet of the second air inlet fan 154 and its corresponding second ventilation port 142 and be released outside the box body 110. In the event of a fire, the damper 154a of the first exhaust fan 153 and the damper 154a of the second exhaust fan 154 are closed to prevent the release of toxic gases inside the box body 110. After the fire is extinguished, outside air enters the battery compartment 113 through the second air inlet fan 154 , and the air flows in the battery compartment 113 and is discharged from the battery compartment 113 through the first exhaust fan 153 , thereby bringing the fire extinguishing gas out of the box body 110 .
