[0026] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of the embodiments of the present invention, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0029] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0030] like Figure 1 and Figure 2 As shown, an electrical box according to an embodiment of the present invention includes a main box 110, a cooling box 120 and an air pump 130.

[0031] Specifically, the main housing 110 can accommodate electronic components, and has an air outlet 115 connecting its interior and exterior. The cooling box 120 includes a heat exchange pipe 121, one end of which connects to the interior of the main housing 110, and the other end to an air pump 130. When gas flows within the heat exchange pipe 121, it exchanges heat with the pipe wall, thereby reducing its temperature. The air pump 130 is connected to the heat exchange pipe 121, such as... Figure 2 As shown, the air pump 130 is connected to the heat exchange pipe 121 via a cooling pipe 133. The air pump 130 is connected to an air inlet pipe 131, an air supply pipe 134, and a return air pipe 132. One end of the air inlet pipe 131 is connected to the outside of the main housing 110, one end of the air supply pipe 134 is connected to the inside of the main housing 110, and one end of the return air pipe 132 is connected to the air outlet 115.

[0032] like Figure 7As shown in the diagram, the arrows indicate the direction of gas flow. When the air pump 130 is connected to the inlet duct 131 and the outlet duct 134, the inlet duct 131, air pump 130, outlet duct 134, main housing 110, and outlet 115 are connected, forming a through-flow path within the electrical box, allowing gas to flow along this path. At this time, gas outside the main housing 110 can flow into the main housing 110 through the inlet duct 131 and air pump 130 to exchange heat with the electronic components inside the main housing 110, thus cooling the components. Finally, the gas inside the main housing 110 flows out of the main housing 110 through the outlet 115.

[0033] like Figure 8 As shown in the diagram, the arrows indicate the direction of gas flow. When the air pump 130 is connected to the heat exchange pipe 121 and the return air pipe 132, and the air outlet 115, return air pipe 132, air pump 130, heat exchange pipe 121, and main housing 110 are connected, a circulation path is formed inside the electrical box, allowing gas to flow along this path. At this time, the gas inside the main housing 110 flows from the air outlet 115 through the return air pipe 132 to the air pump 130, and then to the heat exchange pipe 121. The gas undergoes heat exchange within the heat exchange pipe 121, causing its temperature to decrease. The cooled gas flows into the main housing 110, cooling the electronic components inside and increasing its temperature. Finally, the heated gas returns to the air pump 130 through the air outlet 115 and the return air pipe 132, forming a circulation and reducing gas exchange between the inside and outside of the main housing 110.

[0034] In this way, when the electrical box is used outdoors, the air pump 130 can be switched to connect with the air inlet duct 131 and the air outlet duct 134. The air pump 130 drives the air flow inside and outside the main enclosure 110 to cool the electronic components inside the main enclosure 110. Furthermore, the air pump 130 increases the airflow rate and volume, improving the heat dissipation efficiency of the electrical box. In rainy weather, the air pump 130 can be switched to connect with the heat exchange duct 121 and the return air duct 132, significantly reducing the air exchange between the inside and outside of the main enclosure 110. This prevents excessive external moisture from entering the main enclosure 110 and corroding the electronic components, thus extending the service life of the electrical box.

[0035] like Figure 2As shown, a storage cavity 111 is formed inside the main housing 110, where electronic components can be stored. The main housing 110 is also provided with an air supply duct 113, and both the air supply pipe 134 and the heat exchange pipe 121 are connected to and communicate with the air supply duct 113. The air supply duct 113 and the air outlet 115 are both located on the peripheral wall of the main housing 110. The main housing 110 has opposing first side walls 112 and second side walls 114. The air supply duct 113 is located on the first side wall 112, and the air outlet 115 is located on the second side wall 114. The air supply duct 113 communicates with the receiving cavity 111, and the air outlet 115 penetrates the second side wall 114 in the thickness direction to connect the receiving cavity 111 with the outside of the main housing 110. Gas can enter the main housing 110 from the air supply duct 113 and flow out of the main housing 110 from the air outlet 115. The air supply duct 113 and the air outlet 115 are respectively provided on the first side wall 112 and the second side wall 114 to increase the flow path length of the gas in the receiving cavity 111, so that the gas can fully contact the electronic components for heat exchange. It is understood that when the air supply duct 113 is not provided, the connection positions of the air supply pipe 134 and the heat exchange pipe 121 with the main housing 110 should be spaced apart from the air outlet 115.

[0036] The connection or disconnection between the air pump 130 and the air inlet pipe 131, air return pipe 132, cooling pipe 133, and air supply pipe 134 can be switched using a switch valve. Specifically, for example... Figure 2 As shown, the air pump 130 has a first main pipe 1301 and a second main pipe 1302. The air inlet pipe 131 and the cooling pipe 133 are both connected to and communicate with the first main pipe 1301, and both the air inlet pipe 131 and the first main pipe 1301, and the cooling pipe 133 and the first main pipe 1301, are equipped with switching valves. The return air pipe 132 and the supply air pipe 134 are both connected to and communicate with the second main pipe 1302, and both the return air pipe 132 and the second main pipe 1302, and the supply air pipe 134 and the second main pipe 1302, are equipped with switching valves. By controlling the opening or closing of the switching valves, the connection or disconnection between the air pump 130 and the air inlet pipe 131, the return air pipe 132, the cooling pipe 133, and the supply air pipe 134 can be controlled.

[0037] According to an embodiment of the present invention, the electrical box is equipped with an air pump 130, a cooling box 120, and a return air pipe 132. The air pump 130 can be connected or disconnected from the air inlet pipe 131, the return air pipe 132, the cooling pipe 133, and the air supply pipe 134. When the air pump 130 is connected to the air inlet pipe 131 and the air supply pipe 134, a through flow path is formed inside the electrical box. The gas inside and outside the main box 110 circulates through the through flow path to dissipate heat from the electrical box. When the air pump 130 is connected to the heat exchange pipe 121 and the return air pipe 132, a circulation flow path is formed inside the electrical box. The gas inside the main box 110 circulates and cools down through the circulation flow path to dissipate heat from the electrical box. On the one hand, the air pump 130 can increase the gas flow rate and air volume, thereby improving the heat dissipation efficiency of the electrical box. On the other hand, in rainy weather, the air pump 130 can be switched to connect with the heat exchange pipe 121 and the return air pipe 132 to form a circulation path, thereby avoiding gas exchange between the inside and outside of the main box 110, or significantly reducing gas exchange between the inside and outside of the main box 110, preventing a large amount of external moisture from entering the main box 110 and corroding electronic components, and improving the service life of the electrical box.

[0038] like Figure 2 As shown, according to some embodiments of the present invention, the electrical box further includes an adjusting device 140, which is located at the air outlet 115. The adjusting device 140 is used to adjust the opening of the air outlet 115 so that the air outlet 115 is connected to or isolated from the outside of the main box 110. For example, the adjusting device 140 can be a louvered structure, which includes a frame and a plurality of blades rotatably connected to the frame. By adjusting the rotation angle of the blades, the opening of the air outlet 115 is adjusted. When the air pump 130 is connected to the air inlet pipe 131 and the air outlet pipe 134, and a through flow path is formed inside the electrical box, the air outlet 115 is connected to the outside of the main box 110; when the air pump 130 is connected to the heat exchange pipe 121 and the return air pipe 132, and a circulating flow path is formed inside the electrical box, the air outlet 115 is isolated from the outside of the main box 110 to seal the main box 110 and prevent external moisture from entering the main box 110.

[0039] like Figure 5As shown, according to some embodiments of the present invention, the adjusting device 140 includes a baffle 141 and a first driving assembly 142. The first driving assembly 142 is connected to the baffle 141 to drive the baffle 141 to move between a first position and a second position. When the baffle 141 is in the first position, the baffle 141 blocks the air outlet 115, and the air outlet 115 is isolated from the outside of the main housing 110. When the baffle 141 moves from the first position to the second position, the baffle 141 moves away from the air outlet 115, and the air outlet 115 communicates with the outside of the main housing 110. The first driving assembly 142 can be a telescopic rod structure. The baffle 141 is rotatably connected to the main housing 110, and the telescopic end of the first driving assembly 142 is connected to the baffle 141. The extension or retraction of the first driving assembly 142 drives the baffle 141 to rotate between the first position and the second position. When the baffle 141 is in the first position, the baffle 141 can be embedded in the air outlet 115 or abut against the air outlet 115 to block the air outlet 115. Or, as Figure 5 As shown, the regulating device 140 also includes an air outlet box 144, which is connected to the main housing 110 and extends around the air outlet 115. The side of the air outlet box 144 opposite to the air outlet 115 is open. When the baffle 141 is in the first position, the baffle 141 blocks the side of the air outlet box 144 opposite to the air outlet 115. In some embodiments, the electrical box also includes a first filter element 116, which may be disposed inside the air outlet 115 to prevent dust from the external environment from entering the interior of the main housing 110 through the air outlet 115. Alternatively, the first filter element 116 may also be disposed inside the air outlet box 144.

[0040] According to some embodiments of the present invention, the first drive assembly 142 includes a storage box 1421, a first guide rod 1422, a first sliding block 1423, and a first drive motor 1424. The storage box 1421 is fixedly connected to the main housing 110. The first guide rod 1422 is rotatably disposed within the storage box 1421 to provide protection and reduce the probability of failure of the first guide rod 1422. The first drive motor 1424 is drively connected to the first guide rod 1422, and one end of the first guide rod 1422 is connected to the output end of the first drive motor 1424, enabling the first drive motor 1424 to drive the first guide rod 1422 to rotate. The first sliding block 1423 is sleeved on the first guide rod 1422 and can move along the first guide rod 1422. The first sliding block 1423 extends out of the storage box 1421 and is connected to the baffle 141. Figure 6As shown, the storage box 1421 has a movement opening 1426 on one side, which extends along the length of the first guide rod 1422. The first sliding block 1423 passes through the movement opening 1426. The first guide rod 1422 is a screw, and the first sliding block 1423 is threadedly connected to the first guide rod 1422. The first drive motor 1424 drives the first guide rod 1422 to rotate, thereby causing the first sliding block 1423 to move along the first guide rod 1422.

[0041] like Figure 5 As shown, in some embodiments, the air outlet 115 is located on the second side wall 114 of the main housing 110. The first guide rod 1422 extends vertically. When the first sliding block 1423 moves along the first guide rod 1422, it drives the baffle 141 to move up and down to move closer to or away from the air outlet 115. In this way, the baffle 141 moves parallel or approximately parallel to the outer wall of the main housing 110, occupying a small space. Furthermore, it is understood that when the electrical box is used outdoors, due to the complex external environment, by setting the first guide rod 1422 to extend vertically, the risk of collision between the baffle 141 and the first drive assembly 142 and other objects during movement can be reduced. The first drive assembly 142 also includes a first telescopic drive member 1425, which is telescopic in a direction perpendicular to the air outlet 115. The first telescopic drive member 1425 is connected to the first sliding block 1423. The baffle 141 is connected to the telescopic end of the first telescopic drive member 1425. The first telescopic drive member 1425 drives the baffle 141 to move closer to the air outlet 115 in a direction perpendicular to the air outlet 115, so that the baffle 141 fits against the main housing 110 and improves the sealing performance; or it drives the baffle 141 to move away from the air outlet 115 in a direction perpendicular to the air outlet 115, so as to avoid interference between the baffle 141 and the main housing 110 during the movement.

[0042] like Figure 5 and Figure 6As shown, according to some embodiments of the present invention, the adjusting device 140 further includes a winding assembly, which includes a winding box 143, a winding roller 1431, a sealing strip 1432, and a spring 1433. The winding roller 1431, the sealing strip 1432, and the spring 1433 are all disposed inside the winding box 143. The winding roller 1431 is rotatably connected to the winding box 143. The sealing strip 1432 is wound around the winding roller 1431 and can extend out of the winding box 143. One end of the sealing strip 1432 is connected to the portion of the first sliding block 1423 located inside the storage box 1421. The sealing strip 1432 covers the movement opening 1426 of the storage box 1421 to prevent dust from the external environment from entering the storage box 1421. The spring 1433 is connected to the take-up roller 1431. The spring 1433 is elastically deformable to drive the take-up roller 1431 to rewind, thereby winding the sealing tape 1432 onto the take-up roller 1431. When the first sliding block 1423 moves along the first guide rod 1422 and away from the take-up box 143, the first sliding block 1423 pulls the sealing tape 1432 to move, and the sealing tape 1432 blocks the portion of the moving opening 1426 located between the first sliding block 1423 and the take-up box 143. When the first sliding block 1423 approaches the take-up box 143, the spring 1433 drives the take-up roller 1431 to rotate, and the sealing tape 1432 is wound onto the take-up roller 1431. In some embodiments, there are two sets of take-up assemblies, and in the extension direction of the first guide rod 1422, the two sets of take-up assemblies are respectively disposed on both sides of the first sliding block 1423.

[0043] like Figure 2 and Figure 4 As shown, according to some embodiments of the present invention, the cooling box 120 further includes a shell 122 and a heat dissipation assembly 123. The shell 122 is connected to the main box body 110. Specifically, the shell 122 can be welded to the main box body 110 or fixed to the main box body 110 by fasteners. A heat exchange pipe 121 is disposed inside the shell 122, and the shell 122 is filled with a heat exchange medium, which is in contact with the outer wall of the heat exchange pipe 121. The heat dissipation assembly 123 is disposed on the outer wall of the shell 122 and is in close contact with the shell 122 to dissipate heat from the shell 122. The heat of the gas in the heat exchange pipe 121 is conducted to the heat dissipation assembly 123 through the heat exchange pipe 121, the heat exchange medium, and the shell 122. The heat dissipation assembly 123 can be a water-cooled heat dissipation structure or a semiconductor cooling structure, etc. In some embodiments, the heat dissipation assembly 123 includes a cooling chip 1231 and a heat sink 1232, the cooling surface of the cooling chip 1231 is in contact with the housing 122, and the heat sink is connected to the heat dissipation surface of the cooling chip 1231.

[0044] like Figure 1 and Figure 2As shown, according to some embodiments of the present invention, the electrical box further includes a maintenance box 150 and a second drive assembly 151. The second drive assembly 151 is connected to the main housing 110 and to the maintenance box 150, and is capable of driving the maintenance box 150 to move between a third position and a fourth position. When the maintenance box 150 is in the third position, the maintenance box 150 covers the outside of the housing 122, and the heat dissipation assembly 123 is located inside the maintenance box 150. Figure 4 As shown, one side of the maintenance box 150 is open. When the maintenance box 150 is in the third position, it is fastened to the side of the cooling box 120 away from the main body 110, forming a closed space between the outer wall of the cooling box 120 and the maintenance box 150. The heat dissipation component 123 is located within this closed space. When the through flow path is connected, the maintenance box 150 is in the third position to protect the heat dissipation component 123 and prevent dust and other contaminants from falling on it, thus reducing its heat dissipation effect. When the maintenance box 150 is in the fourth position, it is away from the housing 122, and the heat dissipation component 123 is exposed to the external environment. When the circulation flow path is connected, the maintenance box 150 is in the fourth position, and the heat dissipation component 123 is exposed to the external environment. The heat is carried away by air or rainwater from the external environment, thereby improving the heat dissipation speed of the heat dissipation component 123.

[0045] like Figure 2 and Figure 4 As shown, according to some embodiments of the present invention, when the maintenance box 150 is in the third position, the maintenance box 150 is fastened to the side of the housing 122 away from the main housing 110. Figure 4 As shown, a fixing frame 124 is welded to the outer wall of the housing 122. The fixing frame 124 is located on the side of the housing 122 away from the main housing 110. The heat dissipation assembly 123 is connected to the fixing frame 124. When the maintenance box 150 is in the third position, the inner wall of the maintenance box 150 is fitted and fixed with the fixing frame 124. The second drive assembly 151 includes a second telescopic drive member 152 and a rotation drive member 153. The telescopic direction of the second telescopic drive member 152 is perpendicular to the side of the housing 122 away from the main housing 110 (e.g., ...). Figure 2(in the left and right directions). The rotating drive 153 is connected to the telescopic end of the second telescopic drive 152, and the maintenance box 150 is connected to the rotating end of the rotating drive 153. The rotation axis of the rotating drive 153 is parallel to the telescopic direction of the second telescopic drive 152. When the maintenance box 150 moves from the fourth position to the third position, the rotating drive 153 drives the maintenance box 150 to rotate a certain angle, so that the maintenance box 150 is opposite to the shell 122 of the cooling box 120. Then, the second telescopic drive 152 retracts, and the maintenance box 150 approaches the shell 122 and is fastened to the side of the shell 122 away from the main box body 110. When the maintenance box 150 moves from the third position to the fourth position, the second telescopic drive 152 extends, and the maintenance box 150 disengages from the shell 122. Then, the rotating drive 153 drives the maintenance box 150 to rotate a certain angle and reach the fourth position.

[0046] like Figure 1 and Figure 4 As shown, in some embodiments, at least one support rod 156 is provided on the outer wall of the main housing 110. A cover plate 155 is connected to one end of the support rod 156 away from the main housing 110. When the maintenance box 150 is in the fourth position, the open side of the maintenance box 150 covers the side of the cover plate 155 away from the support rod 156, preventing rainwater or other impurities from entering the maintenance box 150. In some embodiments, the support rod 156 can be a telescopic rod.

[0047] like Figure 2 and Figure 3 As shown, according to some embodiments of the present invention, the electrical box further includes a cleaning device 160, which is connected to the maintenance box 150. The cleaning device 160 includes a water tank 161, a water pump, and a nozzle 163. The water tank 161, the water pump (not shown in the figure), and the nozzle 163 are connected in sequence. The nozzle 163 is connected to the water pump through a water supply pipe 162. The nozzle 163 is disposed inside the maintenance box 150. When the maintenance box 150 is in the third position, the nozzle 163 can spray cleaning liquid toward the heat dissipation assembly 123 to clean the heat dissipation assembly 123 and ensure the heat dissipation effect of the heat dissipation assembly 123. Multiple nozzles 163 can be arranged in an array on the inner wall of the maintenance box 150. Alternatively, as... Figure 3As shown, in some embodiments, the curing box 150 may be equipped with a second guide rod 164, a second sliding block 165, and a second drive motor 166. The second guide rod 164 is rotatably connected to the curing box 150, and the second drive motor 166 is drively connected to the second guide rod 164 to drive the second guide rod 164 to rotate. The nozzle 163 is disposed on the second sliding block 165. The second guide rod 164 is a screw, and the second sliding block 165 is sleeved on the second guide rod 164 and threadedly connected to the second guide rod 164. The inner wall of the curing box 150 is provided with a guide groove that extends along the length of the second guide rod 164. Part of the second sliding block 165 is engaged in the guide groove. When the second drive motor 166 drives the second guide rod 164 to rotate, the second sliding block 165 can move along the second guide rod 164, thereby driving the nozzle 163 to move relative to the curing box 150, thereby cleaning various parts of the heat dissipation assembly 123.

[0048] According to some embodiments of the present invention, the bottom of the maintenance box 150 is provided with a first connector 154, which communicates with the interior of the maintenance box 150. The main body 110 is provided with a drain pipe 195 and a lifting platform 190. One end of the drain pipe 195 is provided with a second connector 196, which is connected to the lifting platform 190. The lifting platform 190 can drive the second connector 196 to move closer to or away from the first connector 154, so that the second connector 196 connects or disconnects from the first connector 154, reducing wear on the maintenance box 150 during movement caused by the drain pipe 195. Figure 4 As shown, the lifting platform 190 includes a connecting rod 191, a connecting plate 192, and a lifting drive component 193. One end of the connecting rod 191 is connected to the main housing 110, and the other end is connected to the connecting plate 192, which is L-shaped. The second connector 196 is connected to the sewage pipe 195 via a connecting hose 194, which passes through the connecting plate 192 and is fixed to it. One end of the lifting drive component 193 is connected to the connecting plate 192, and the other end is connected to the second connector 196, so as to drive the second connector 196 to move up and down to move closer to or away from the first connector 154. In some embodiments, the connecting rod 191 is a telescopic rod, and the telescopic direction of the connecting rod 191 is parallel to the telescopic direction of the second telescopic drive component 152, so as to flexibly adjust the position of the second connector 196 so that the second connector 196 can be connected to the first connector 154.

[0049] like Figure 2 and Figure 7 As shown, according to some embodiments of the present invention, the electrical box also includes an air inlet box 170, an air inlet pipe 131 connected to the air inlet box 170, an air inlet 170 having an air inlet 171, and a second filter element 172 provided inside the air inlet 171 to filter impurities, dust and the like in the gas.

[0050] According to some embodiments of the present invention, the electrical box further includes a mounting bracket 180 and a top box 182. The mounting bracket 180 is connected to the main box 110. Specifically, the mounting bracket 180 is located on the top outer side of the main box 110. The mounting bracket 180 forms a mounting space 181, in which the air pump 130 and the air inlet box 170 are both disposed. The air pump 130 and the air inlet box 170 can be fixedly connected to the mounting bracket 180. The top box 182 is connected to the mounting bracket 180, and the top box 182 is movable relative to the mounting bracket 180 between a fifth position and a sixth position. When the top box 182 is in the fifth position, the top box 182 blocks the mounting bracket 180, and the air inlet 171 is in a closed state; when the top box 182 is in the sixth position, the top box 182 is away from the mounting bracket 180, and the air inlet 171 is in an open state. Figure 2 As shown, the top box 182 includes a rain guide canopy 1821, side panels 1822, and lifting columns 1823. One end of the lifting column 1823 is connected to the mounting frame 180, and the other end is connected to the rain guide canopy 1821. The lifting column 1823 can extend and retract in the vertical direction to move the rain guide canopy 1821 up and down. Multiple side panels 1822 are connected to the lower end of the rain guide canopy 1821 and are distributed along the circumferential direction of the rain guide canopy 1821. The rain guide canopy 1821 is cone-shaped to allow rainwater to flow downwards and prevent rainwater accumulation. When the top box 182 is in the fifth position, the lifting column 1823 retracts, and the side plate 1822 abuts against the periphery of the mounting frame 180. The side plate 1822 and the rain canopy 1821 together enclose the mounting frame 180 to close the installation space 181. At the same time, the side plate 1822 can block the air inlet 171 of the air inlet box 170 to prevent moisture from entering.

[0051] The following is an example of an electrical box to facilitate understanding of its operation: Reference Figure 7 As shown, when it is not raining, the lifting column 1823 extends to move the top box 182 to the sixth position; the second drive assembly 151 drives the baffle 141 to move towards the second position, the baffle 141 moves away from the air outlet 115, and the air outlet 115 is connected to the outside of the main box 110. Furthermore, the air pump 130 is connected to both the air inlet duct 131 and the air supply duct 134, forming a through-flow path, allowing gas to flow along this path within the electrical box. Specifically, gas from the external environment enters the air inlet box 170 through the air inlet 171, and then enters the air pump 130 through the air inlet duct 131. The air pump 130 pumps the gas through the air supply duct 134 to the air supply slot 113. The gas enters the main box 110 from the air inlet slot and comes into contact with the electronic components inside the main box 110 for heat exchange, lowering the temperature of the electronic components. Finally, the gas flows out of the main box 110 through the air outlet 115.

[0052] Reference Figure 8As shown, when it rains, the air pump 130 is disconnected from both the air inlet pipe 131 and the air outlet pipe 134, while the air pump 130 is connected to both the air return pipe 132 and the cooling pipe 133, creating a continuous circulation path. Gas flows along this path within the electrical box. Gas from the main housing 110 returns to the air pump 130 from the air outlet 115 via the air return pipe 132. The air pump 130 then pumps the gas through the cooling pipe 133 to the heat exchange pipe 121 for heat exchange, lowering the gas temperature. The cooled gas then enters the main housing 110 through the air outlet 113 and comes into contact with the electronic components for heat exchange, raising the gas temperature. The heated gas then returns to the air pump 130 through the air outlet 115 and the air return pipe 132 for the next cycle.

[0053] Furthermore, the lifting column 1823 retracts, and the top box 182 moves towards the fifth position, causing the side plate 1822 to block the mounting bracket 180 and the air inlet 171 to close. The first drive assembly 142 drives the baffle 141 to move towards the first position, the first drive motor 1424 drives the first guide rod 1422 to rotate, and the first sliding block 1423 moves downward along the first guide rod 1422. When the first sliding block 1423 moves to a certain position, the baffle 141 is opposite to the opening of the air outlet box 144; the first telescopic drive member 1425 retracts, driving the baffle 141 to move towards the air outlet box 144, so that the baffle 141 blocks the air outlet box 144, the air outlet 115 and the main box 110 are isolated from the outside. The lifting platform 190 drives the second connector 196 to disengage from the first connector 154, and the lifting drive member 193 retracts, causing the second connector 196 to disengage from the first connector 154. The second driving member drives the maintenance box 150 to move to the fourth position. The second telescopic driving member 152 drives the maintenance box 150 to move away from the housing 122 of the cooling box 120, causing the maintenance box 150 to separate from the housing 122. Then, the rotation driving member 153 operates, causing the maintenance box 150 to rotate at a certain angle, so that the maintenance box 150 is opposite to the cover plate 155. Afterwards, the second telescopic driving member 152 retracts, causing the maintenance box 150 to move towards the cover plate 155, so that the open side of the maintenance box 150 is in contact with the cover plate 155. This exposes the heat sink 1232 of the heat dissipation assembly 123 to the external environment, which is beneficial for the heat dissipation assembly 123 to dissipate heat.

[0054] When the heat dissipation component 123 needs to be cleaned, the second drive component 151 drives the maintenance box 150 to move to the third position, the maintenance box 150 is fastened to the housing 122, and the heat dissipation component 123 is located between the housing 122 and the maintenance box 150; the lifting platform 190 drives the second connector 196 to move toward the first connector 154, so that the second connector 196 is connected and communicated with the first connector 154; the water pump is started to pump the cleaning fluid to the nozzle 163, thereby cleaning the heat dissipation component 123. During this process, the second drive motor 166 drives the second guide rod 164 to rotate, and the second sliding block 165 moves along the second guide rod 164 to drive the nozzle 163 to move relative to the heat dissipation component 123, thereby cleaning different parts of the heat dissipation component 123; the sewage generated during the cleaning process is concentrated at the bottom of the maintenance box 150 and flows into the sewage pipe 195 through the first connector 154 and the second connector 196, and then into the external drainage pipe.

[0055] In summary, the embodiments of the present invention provide an electrical box that has at least the following advantages: 1. By using an air pump 130 to drive the gas flow, the gas velocity and air volume are increased, thereby improving the heat dissipation efficiency of the electrical box. 2. When it rains, the air pump 130 is connected to the return air pipe 132 and the cooling pipe 133, and the circulation path is unobstructed, thereby avoiding gas exchange between the inside and outside of the main housing 110, or greatly reducing gas exchange between the inside and outside of the main housing 110, preventing a large amount of external moisture from entering the main housing 110 and causing corrosion to electronic components, and improving the service life of the electrical box. 3. The heat dissipation components 123 of the cooling box 120 are cleaned by a cleaning device to ensure the heat dissipation efficiency of the heat dissipation components 123.

[0056] Finally, it should be noted that the above embodiments are only for illustrating the present invention and are not intended to limit the present invention. It should be pointed out that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
