[0006] By adopting the above technical solution, when the energy storage power supply host is in normal use, the heat emitted by the circuit board is released through the radiator, and then the heat is discharged to the outside of the shell through air convection formed by the cooling fans located at both ends; when water flows into the shell from the shutter position, since the circuit board is in the installation box and the radiator is installed at the opening of the installation box, the circuit board can be isolated so that water will not enter the installation box; and the location where the wires are set is protected by the protective cover, so that water and wires are isolated; the above measures greatly improve the overall waterproof level, while ensuring the heat dissipation effect of the host, while improving the waterproof effect of the host.

[0007] Preferably, the outer shell includes a bottom shell, a side shell and a top shell, the bottom shell is plugged into a plurality of side shells along the circumferential direction, and two adjacent side shells are plugged into and matched with each other along the height direction, the top shell cover is arranged on the top of each side shell, and the bottom shell and the side shell, and the top shell and the side shell are detachably connected by connecting parts.

[0008] By adopting the above technical solution, when a part of the outer shell is damaged and needs to be replaced, or the internal structure needs to be repaired, the bottom shell, side shell and top shell can be removed separately for replacement or to facilitate the repair of the internal structure, thereby reducing the cost of maintenance and improving the convenience of maintenance.

[0009] Preferably, the shutters include a plurality of inner shutters and a plurality of outer shutters, and the plurality of inner shutters and the plurality of outer shutters are arranged in a vertically spaced arrangement, and the inner shutters and the outer shutters are arranged in sequence from the inside of the outer shell to the outside, and the inner shutters and the outer shutters are arranged inclined downward.

[0010] By adopting the above technical solution, by arranging inner louvers and outer louvers that are inclined downward, two rows of louvers can achieve double blocking, reducing the amount of water that enters the outer shell through the louvers.

[0011] Preferably, the outer louver is located between two adjacent inner louvers, and the angle between the outer louver and the vertical line is greater than the angle between the inner louver and the vertical line.

[0012] By adopting the above technical solution, the water entering the housing through the shutters can be further reduced without affecting the flow of wind.

[0014] By adopting the above technical solution, although there are outer louvers and inner louvers to block water, water will still enter the casing, and after accumulating, it will affect the internal structure of the host; therefore, when a sudden storm occurs during outdoor use, the cooling fan is stopped, and the isolation space is disconnected from the inside of the casing by an isolation component. When rainwater enters the isolation space through the outer louvers, it will flow into the water outlet, and then flow into the flow chamber through the drain pipe, and the heat generated by the circuit board is taken away by the water before flowing out of the casing; therefore, when the isolation component is used to isolate the inside and outside of the casing and heat cannot be dissipated by ventilation, the installation box can still be cooled by the effect of rainwater, thereby indirectly cooling the circuit board.

[0016] By adopting the above technical solution, the first driving member drives the first winding shaft to rotate to unwind the water retaining film, and synchronously starts the driving component to pull the free end of the water retaining film toward the bottom end of the isolation space, thereby achieving the isolation space and the interior of the shell being separated by the water retaining film. The structure is simple and has a good isolation effect.

[0018] By adopting the above technical solution, the second driving member is started to drive the second winding shaft to rotate and the pull rope is wound up, thereby pulling the water retaining film; the structure is simple and the process of pulling the water retaining film to unfold is stable.

[0019] Preferably, the first driving member is a first twisting rod, one end of which is connected to the first winding shaft and the other end extends out of the outer shell; the second driving member is a second twisting rod, one end of which is connected to the second winding shaft and the other end extends out of the outer shell.

[0020] By adopting the above technical solution, the operator can directly drive the second winding shaft to rotate by rotating the second twisting rod, thereby unfolding the water retaining film; and can drive the first winding shaft to rotate by rotating the first twisting rod, thereby rewinding the water retaining film; the operation is simple and convenient.

[0021] Preferably, a stop bar is installed at the free end of the water retaining film, and limiting slide grooves for the sliding movement of the two ends of the stop bar are respectively opened on both sides of the isolation space; a pressure plate is installed in the limiting slide groove on the side of the water retaining film facing the outer louver, and the pressure plate extends in the extension direction of the limiting slide groove, and the pressure plate slides in the width direction of the limiting slide groove, and the outer shell is installed with a third driving member for driving the pressure plate to slide.

In order to improve the water-retaining effect of the water retaining film, after the deployment is completed, the pressure plate is driven by the third driving member to move toward the part of the water retaining film in the limiting slide groove until the pressure plate presses the water retaining film against the inner wall of the limiting slide groove, thereby improving the sealing of the water retaining film after deployment. In addition, when the water retaining film is rolled up, the pressure plate can be driven to move to limit the gear bar to the top of the isolation space.

[0023] Preferably, the third driving member includes a driving screw extending in the sliding direction of the pressure plate, the driving screw is threadedly mounted on the outer shell, one end of the driving screw is rotatably mounted on the pressure plate, and the other end extends out of the outer shell.

[0024] By adopting the above technical solution, the operator can drive the pressure plate to slide by rotating the end of the driving screw outside the shell, which is easy to operate and has high driving stability.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the energy storage power supply host is in normal use, the heat emitted by the circuit board is released through the radiator, and then the heat is discharged to the outside of the shell through the air convection formed by the cooling fans at both ends; when water flows into the shell from the shutter position, since the circuit board is in the installation box, the radiator is installed at the opening of the installation box, so the circuit board can be isolated, so that water will not enter the installation box; and the location where the wires are set is protected by the protective cover, so that water and wires are isolated; the above measures greatly improve the overall waterproof level, while ensuring the heat dissipation effect of the host, while improving the waterproof effect of the host; 2. When a part of the shell is damaged and needs to be replaced, or the internal structure needs to be repaired, the bottom shell, side shell and top shell can be removed separately for replacement or to facilitate the repair of the internal structure, which reduces the cost of repair and improves the convenience of repair; 3. When a sudden storm occurs during outdoor use, the cooling fan is stopped, and the isolation space is disconnected from the inside of the shell by an isolation component. When rainwater enters the isolation space through the external louver, it flows into the water outlet, and then flows into the flow chamber through the drain pipe. The heat generated by the circuit board is taken away by the water and then flows out of the shell. Therefore, when the isolation component is used to isolate the inside and outside of the shell and heat cannot be dissipated by ventilation, the installation box can still be cooled by the effect of rainwater, thereby indirectly cooling the circuit board.
