[0041] Embodiment 1

[0042] The present embodiment provides a heat dissipation and waterproof structure 100, which can be installed on the box 200 of the containerized energy storage system to dissipate heat for the components in the box 200. When the containerized energy storage system is placed in an external environment, the heat dissipation and waterproof structure 100 can also prevent rainwater from entering the box 200 through the heat dissipation and waterproof structure 100, so as to avoid damage to the components in the box 200.

[0043] like Figures 1 to 3As shown, the heat dissipation and waterproof structure 100 includes a shell 1, a drainage component 2 and a shielding component 3. The shell 1 is arranged on the side wall of the box body 200. The shell 1 has a first side wall 11 and a second side wall 12 that are arranged opposite to each other. A first ventilation hole 111 is arranged on the first side wall 11. The first ventilation hole 111 is used to connect the first cavity of the shell 1 with the external environment. A second ventilation hole 121 is arranged on the second side wall 12. The second ventilation hole 121 is used to connect the first cavity and the second cavity of the box body 200, that is, the gas in the external environment can be exchanged with the gas in the second cavity through the first ventilation hole 111 and the second ventilation hole 121 to dissipate heat to the components in the second cavity. The drainage assembly 2 includes a movable panel, which is arranged on the top wall of the shell 1. The movable panel and the outer wall of the shell 1 form a water storage tank, which is used to accommodate liquid. The liquid in the water storage tank is used to apply a force toward the bottom wall of the shell 1 to the movable panel. When liquid exceeding a first preset amount accumulates in the water storage tank, the gravity exerted on the liquid can move the movable panel so that the movable panel can leave the first position. The shielding assembly 3 includes a shielding plate 32 and a pull rope 31. The shielding plate 32 is connected to the movable panel through the pull rope 31. Since the movable panel can be moved by the gravity of the accumulated liquid, the movable panel can drive the shielding plate 32 to slide relative to the first side wall 11 through the pull rope 31, so that the shielding plate 32 can move to the second position and abut against the upper side wall of the first ventilation hole 111. When the shielding plate 32 is in the second position, the shielding plate 32 can shield the first ventilation hole 111 to prevent rainwater from entering the first cavity through the first ventilation hole 111, and rainwater cannot enter the second cavity through the housing 1, thereby preventing damage to the components in the box 200. The shielding plate 32 abuts against the upper side wall of the first ventilation hole 111, which also limits the movement of the movable panel under the gravity of the accumulated liquid. When the shielding plate 32 moves to the second position, it will be blocked by the upper side wall of the first ventilation hole 111, and the shielding plate 32 will not be able to move further, thereby ensuring effective shielding of the first ventilation hole 111.

[0044] Optionally, the shielding assembly 3 also includes a hanging rod 33, which is arranged in the first cavity, and the pull rope 31 is hung on the hanging rod 33, one end of the pull rope is connected to the shielding plate 32, and the other end of the pull rope 31 is connected to the movable panel, and both ends of the pull rope 31 are located below the hanging rod 33, so that the movable panel and the shielding plate 32 can move toward or away from each other in the vertical direction. When one end of the pull rope 31 is upward, the other end of the pull rope 31 must be downward, and when the movable panel moves downward due to the gravity of the liquid in the water tank, the pull rope 31 will pull the shielding plate 32 to move upward. In specific implementation, the shielding plate 32 is placed below the first ventilation hole 111, and when the pull rope 31 pulls the shielding plate 32 upward, the shielding plate 32 can be moved into the first ventilation hole 111 and abut against the upper side wall of the first ventilation hole 111.

[0045] Optionally, N first ventilation holes 111 are provided, and the shielding plate 32 includes a mounting rod 322 and N sub-plates 321. The N sub-plates 321 are arranged at intervals and all abut against the first side wall 11. Two adjacent sub-plates 321 are connected by the mounting rod 322. A slide groove extending in the vertical direction is provided on the first side wall 11, and the mounting rod 322 is passed through the slide groove. The setting of the slide groove limits the relative movement between the N sub-plates 321 when the shielding plate 32 moves in the vertical direction. The N sub-plates 321 are always abutted against the first side wall 11, thereby ensuring the blocking effect of the first ventilation hole 111.

[0046] Optionally, N accommodating grooves are further provided on the first side wall 11, one accommodating groove is connected to the lower side wall of the first ventilation hole 111, and the sub-plate 321 can be moved from the accommodating groove to the first ventilation hole 111, that is, when the sub-plate 321 is not needed to block the first ventilation hole 111, the sub-plate 321 can be stored in the accommodating groove.

[0047] Preferably, the sub-plate 321 is inclined away from the first surface of the second side wall 12, and a guide groove 3211 is provided on the first surface. One end of the upper side wall of the first surface close to the first ventilation hole 111 is closer to the second side wall 12 than the other end of the first surface close to the lower side wall of the first ventilation hole 111. When rainwater hits the sub-plate 321, it will slide along the guide groove 3211 on the sub-plate 321 toward the side away from the first cavity.

[0048] Preferably, a slit 3212 is provided on the second surface of the sub-plate 321 abutting against the upper side wall of the first ventilation hole 111. When the shielding plate 32 moves to the second position, the second surface abuts against the upper side wall of the first ventilation hole 111, and the gas in the external environment can only enter the first cavity through the slit 3212, while rainwater is blocked outside the first cavity by the sub-plate 321.

[0049] In addition, the movable plate includes a top plate 21, a connecting rod 23, a connecting plate 22 and a spring 24. The top plate 21 and the connecting plate 22 are connected by the connecting rod 23. The spring 24 is sleeved on the connecting rod 23, that is, the top plate 21 and the connecting plate 22 always keep moving synchronously, in the same direction and at the same distance. The drainage assembly 2 also includes a drainage box 25. The drainage box 25 has a third cavity. The drainage box 25 is arranged on the top wall of the shell 1. The opening of the drainage box 25 is located outside the first cavity. The top plate 21 covers the opening. The connecting plate 22 connected to the top plate 21 is located in the first cavity. The connecting rod 23 passes through the bottom of the drainage box 25 so that the connecting plate 22 is located outside the drainage box 25. One end of the spring 24 abuts the top plate 21, and the other end abuts the bottom wall of the third cavity. Because the drainage box 25 is fixed relative to the shell 1, the spring 24 is clamped between the top plate 21 and the bottom wall of the third chamber. When the spring 24 is not squeezed, the spring 24 can be used to place the movable plate in the first position. When the liquid in the water storage tank accumulates to more than the first preset amount, the spring 24 will be compressed, and the movable plate will move toward the bottom wall of the shell 1, that is, the movable plate leaves the first position, and the movable plate will drive the baffle plate 32 to move. As the liquid in the water storage tank continues to increase, the baffle plate 32 will eventually move to the second position.

[0050] Optionally, a drainage hole 211 is provided on the top plate 21, and the drainage assembly 2 further includes a blocking rod 26, which is inserted into the drainage hole 211, and the first end of the blocking rod 26 is connected to the drainage box 25, and the second end of the blocking rod 26 is provided with a shielding protrusion 261, which is located on the side of the top plate 21 away from the connecting plate 22, and the shielding protrusion 261 blocks the drainage hole 211 only when the movable plate is located at the first position. When the liquid in the water storage tank accumulates to a first preset amount, the movable plate will move toward the bottom wall of the housing 1. At this time, due to the change in the relative position of the top plate 21 and the blocking rod 26, the shielding protrusion 261 will be located above the top plate 21 and can no longer block the drainage hole 211, and the liquid in the water storage tank can flow into the drainage box 25 through the drainage hole 211.

[0051] Optionally, the drainage assembly 2 further includes a condenser 27, the inlet of which is connected to the third cavity, and the outlet of which extends out of the first cavity, that is, the liquid entering the third cavity can be discharged through the condenser 27. When the outside is in a rainy environment, the temperature drops, and the rainwater accumulated on the top plate 21 is discharged through the condenser 27, and the temperature around the condenser 27 drops. At this time, although the air volume entering the first cavity through the first vent 111 is reduced due to the blocking of the first vent 111 by the shielding plate 32, the condenser 27 that continuously discharges liquid can also maintain a good heat dissipation and cooling effect.

[0052] Preferably, a through hole 212 is provided on the top plate 21. Different from the drainage hole 211, the through hole 212 is always connected to the third chamber. Even if the movable plate does not leave the first position, the liquid accumulated on the top plate 21 can flow to the drainage box 25 through the through hole 212 at any time, and then be discharged from the condenser 27. When the external environment is in light rain, less liquid falls on the top plate 21 and will be directly drained through the drainage box 25. When the external environment is in heavy rain, more liquid falls on the top plate 21 and cannot be drained through the drainage box 25 in time. At this time, the drainage hole 211 is opened to accelerate the discharge of liquid. When the external environment is in light rain, rainwater rarely enters the second cavity through the first cavity, so there is no need to use the shielding plate 32 to block the first ventilation hole 111. When the external environment is in heavy rain, rainwater easily enters the second cavity through the first cavity. At this time, the liquid accumulated on the top plate 21 that has not been drained away in time will drive the movable plate to move, thereby driving the shielding plate 32 to move to block the first ventilation hole 111. The setting of the drainage hole 211 can avoid excessive liquid accumulation on the top plate 21, but when the continuous rainfall reaches a certain amount, even if the drainage hole 211 is opened, there is still liquid on the top plate 21 that can drive the movable plate to move. In specific implementation, the flow area of ​​the drainage hole 211 and the flow area of ​​the through hole 212 can be set according to actual conditions to ensure that when the rainfall falling on the top plate 21 per minute reaches a predetermined value, the drainage hole 211 will be opened and the shielding plate 32 will block the first ventilation hole 111.

[0053] Furthermore, the heat dissipation and waterproof structure 100 also includes a fan 4, which is arranged in the first cavity. The fan 4 is used to accelerate the exchange of gas between the external environment, the first cavity and the second cavity. The fan 4 is located between the condenser 27 and the second side wall 12. The gas in the external environment can first pass through the condenser 27 when entering the second cavity, so as to reduce the temperature of the gas entering the second cavity.
