Description

Technical Field

[0001] The present application relates to the technical field of power distribution cabinet maintenance, and in particular to a power distribution cabinet that is easy to maintain and efficient. Background Art

[0002] The power distribution cabinet is an important electrical equipment, mainly used for the distribution, control and protection of electric energy. It usually consists of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment, which are assembled in a closed or semi-closed metal cabinet or on a screen to form a low-voltage power distribution device. The power distribution cabinet can manually or automatically connect or disconnect the circuit, play the role of distributing electric energy during normal operation, and provide protection when there is a problem with the circuit.

[0003] In the related art, an outdoor power distribution cabinet is an electrical device specially used in outdoor environments. Its design and manufacture need to take into account a variety of special factors to ensure its stability and safety. The equipment inside the power distribution cabinet will generate heat during operation. If this heat cannot be effectively dissipated, it will cause the internal temperature of the equipment to rise. Overheating will reduce the performance of electrical components and may even damage them. Therefore, the outer shell of the power distribution cabinet is usually provided with heat dissipation holes for heat dissipation inside the power distribution cabinet.

[0004] For outdoor power distribution cabinets, these heat dissipation holes on the outer shell can help the power distribution cabinet to dissipate heat well, but when it rains, especially when accompanied by wind, rainwater is easily blown into the heat dissipation holes by the wind. The wind blows rainwater into the power distribution cabinet through the heat dissipation holes, which causes rainwater to accumulate inside the power distribution cabinet, causing moisture inside the power distribution cabinet, which poses a greater safety hazard to the equipment in the power distribution cabinet during operation. However, if the heat dissipation holes are closed, the overall heat dissipation of the power distribution cabinet will be affected.

[0005] At the same time, after rainwater enters the distribution cabinet from the heat dissipation holes, the staff needs to maintain the distribution cabinet in time, which makes the overall use of the distribution cabinet very inconvenient. Summary of the invention

[0006] The present application provides a distribution cabinet that is easy and efficient to maintain. The purpose is that when the distribution cabinet is used outdoors and encounters thunderstorms, it can effectively increase the waterproof performance of the distribution cabinet without affecting the heat dissipation of the distribution cabinet, thereby effectively improving the safety of the outdoor distribution cabinet during use, and can effectively reduce the number of times the staff performs maintenance on the distribution cabinet, thereby making the overall use of the distribution cabinet more convenient and maintenance more efficient.

[0007] The present application provides a power distribution cabinet that is easy to maintain and efficient, and adopts the following technical solutions: A power distribution cabinet that is easy to maintain efficiently, comprising a shell, wherein first heat dissipation holes are provided on both left and right sides of the top of the shell in a vertical direction, and waterproof grooves are provided on both left and right sides of the middle of the shell in a direction close to each other, and second heat dissipation holes are provided on the side walls of the waterproof grooves in a vertical direction; A plurality of first heat dissipation blades are evenly distributed at intervals in the vertical direction at the first heat dissipation holes, and a first driving assembly is provided on the side wall of the shell, and the first driving assembly is used to drive the first heat dissipation blades to rotate. A plurality of second heat dissipation blades are evenly distributed at intervals in the vertical direction at the second heat dissipation holes, and a second driving assembly is provided on the side wall of the shell, and the second driving assembly is used to drive the second heat dissipation blades to rotate.

[0008] By adopting the above technical solution, under normal conditions, when it is not raining, these first heat dissipation blades are in an open state, and the second heat dissipation blades are in a closed state. In this state, the heat in the shell is still dissipated through the first heat dissipation hole. When it rains, the first drive component drives the corresponding first heat dissipation blade to rotate so that it gradually closes, and at the same time, the second drive component drives the corresponding second heat dissipation blade to rotate so that it gradually opens. The purpose of this is to transfer the heat dissipation in the shell from the first heat dissipation hole to the second heat dissipation hole. When the first heat dissipation hole is closed, the heat in the shell can still be dissipated through the second heat dissipation hole, and thus will not affect the normal heat dissipation requirements inside the shell.

[0009] At the same time, since the second heat dissipation hole is opened at the waterproof groove of the shell, the waterproof groove can effectively block rainwater outside the second heat dissipation hole when the second heat dissipation hole is dissipating heat, thereby effectively ensuring that the power distribution cabinet is effectively waterproof without affecting heat dissipation. The use of the waterproof groove can effectively improve the overall waterproof effect of the power distribution cabinet, thereby effectively reducing the number of times the staff performs maintenance on the power distribution cabinet, making the overall use of the power distribution cabinet more convenient and maintenance more efficient.

[0010] Specifically, the presence of the waterproof groove allows a buffer zone to be reserved between the second heat dissipation hole and the outermost side of the shell. This buffer zone allows rainwater to gradually slide downward due to gravity during the process of being blown by the wind, and eventually fall to the bottom of the waterproof groove, rather than being directly blown into the second heat dissipation hole by the wind. The waterproof groove can effectively prevent rainwater from accumulating in the power distribution cabinet. When the power distribution cabinet is used outdoors in thunderstorm weather, the waterproof performance of the power distribution cabinet can be effectively increased without affecting the heat dissipation of the power distribution cabinet, thereby effectively improving the safety of the outdoor power distribution cabinet during use, and effectively reducing the number of times the staff performs maintenance on the power distribution cabinet, thereby making the overall use of the power distribution cabinet more convenient and maintenance more efficient.

[0011] Preferably, the first driving assembly includes a first knob, a first driving gear and a first driven gear, the first driving gear and the first driven gear are both vertically arranged, a first support box is fastened to the side wall of the shell by a fastening bolt, the first knob is rotatably mounted on the outside of the first support box, a corresponding rotating shaft is installed between the first knob and the first driving gear in the horizontal direction, the first driven gear and the first driving gear are meshed and connected, and the first driven gear and the first heat dissipation blade at the top are connected via a corresponding rotating shaft.

[0012] By adopting the above technical solution, specifically, when it is necessary to close the first heat dissipation blade on a rainy day, the first knob is turned to drive the first driving gear to rotate, and the first driving gear drives the first driven gear to rotate during the rotation process, and then the top first heat dissipation blade is driven to rotate through the first driven gear until the first heat dissipation blade is closed.

[0013] Preferably, a first pulley is installed in the vertical direction on the side of the first heat dissipation blade away from the first knob, and the first pulley is fastened to the side wall of the outer shell. A first roller is installed in the vertical direction on the side of multiple first heat dissipation blades away from the first knob, and the first roller is sleeved in the first pulley, and the first roller and the corresponding first heat dissipation blade are connected through a corresponding rotating shaft.

[0014] By adopting the above technical solution, when the top first heat dissipation blade rotates driven by the first driven gear, the first heat dissipation blade drives the first pulley to rotate through the corresponding first roller, and then drives the remaining first heat dissipation blades below to rotate accordingly through the first pulley, and then through the first pulley and the first roller, the top first heat dissipation blade can synchronously drive the remaining first heat dissipation blades to rotate during the rotation process, thereby making the adjustment of these first heat dissipation blades more efficient.

[0015] Preferably, the second driving assembly includes a second knob, a second driving gear and a second driven gear, the second driving gear and the second driven gear are both vertically arranged, a second support box is fastened to the side wall of the shell by a fastening bolt, the second knob is rotatably mounted on the outside of the second support box, a corresponding rotating shaft is horizontally installed between the second knob and the second driving gear, the second driven gear and the second driving gear are meshed and connected, and the second driven gear and the second heat dissipation blade at the top are connected via a corresponding rotating shaft.

[0016] By adopting the above technical solution, the second driven gear drives the second heat dissipation blade to rotate through the corresponding rotating shaft during the rotation process, thereby achieving the adjustment of the angle of the second heat dissipation blade.

[0017] Preferably, a second pulley is installed in the vertical direction on the side of the second heat dissipation blade away from the second knob, and the second pulley is fastened to the side wall of the outer shell. A plurality of second heat dissipation blades are installed in the vertical direction on the side away from the second knob, and the second roller is sleeved in the second pulley, and the second roller and the corresponding second heat dissipation blade are connected via a corresponding rotating shaft.

[0018] By adopting the above technical solution, when the top second heat dissipation blade rotates driven by the second driven gear, the second heat dissipation blade drives the second pulley to rotate via the corresponding second roller, and then drives the remaining second heat dissipation blades below to rotate accordingly via the second pulley, and then the top second heat dissipation blade can synchronously drive the remaining second heat dissipation blades to rotate during the rotation process through the second pulley and the second roller, thereby making the adjustment of these second heat dissipation blades more efficient.

[0019] Preferably, a partition is horizontally provided at the second heat dissipation hole in the power distribution cabinet, and one end of the partition is hingedly connected to the inner wall of the shell.

[0020] By adopting the above technical solution, when the first heat dissipation blade is closed and the second heat dissipation blade is opened, since the heat in the outer shell is accumulated above the outer shell, in order to effectively dissipate the heat above the outer shell from the second heat dissipation blade, a plurality of fans are installed on the top of the outer shell. These fans are used to blow the heat on the top of the outer shell downward to the second heat dissipation blade, thereby achieving the goal of dissipating the heat in the outer shell from the second heat dissipation blade.

[0021] However, when the fan blows the heat downward, it will blow the heat to the bottom of the shell, and thus cannot effectively ensure that the heat is dissipated from the second heat dissipation blade. Therefore, when it is necessary to dissipate the heat from the second heat dissipation blade, the partition is rotated from a vertical state to a horizontal state, and the shell is divided into two independent chambers by the partition. When the fan blows the heat above the shell downward, the partition effectively prevents the heat from being blown to the bottom of the shell by the fan.

[0022] Preferably, a clamping ring for limiting the end of the partition is installed on the inner wall of the shell.

[0023] By adopting the above technical solution, when the partition rotates to a horizontal state, the end of the partition is clamped into the clamp ring, and the clamp ring is used to stabilize the partition. The clamp ring is made of elastic material, which is convenient for clamping or removing the end of the partition.

[0024] Preferably, the partition is located in the middle of the second heat dissipation hole.

[0025] By adopting the above technical solution, the fan can blow the heat to the upper part of the second heat dissipation hole for dissipation, and at the same time, the heat continuously generated by the electrical equipment under the outer shell can be dissipated from the lower part of the second heat dissipation hole, thereby effectively ensuring the overall heat dissipation efficiency of the distribution cabinet.

[0026] Preferably, the bottom of the waterproof groove is arranged to be inclined, and one end of the waterproof groove close to the second heat dissipation hole is in a high position, and one end of the waterproof groove away from the second heat dissipation hole is in a low position.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. The existence of the waterproof groove allows a buffer zone to be reserved between the second heat dissipation hole and the outermost side of the shell. This buffer zone allows rainwater to gradually slide downwards due to gravity during the process of being blown by the wind, and eventually falls on the bottom of the waterproof groove, rather than being directly blown into the second heat dissipation hole by the wind. The waterproof groove can effectively prevent rainwater from accumulating in the power distribution cabinet. When the power distribution cabinet is used outdoors in thunderstorms, the waterproof performance of the power distribution cabinet can be effectively increased without affecting the heat dissipation of the power distribution cabinet, thereby effectively improving the safety of the outdoor power distribution cabinet during use, and effectively reducing the number of times the staff performs maintenance on the power distribution cabinet, thereby making the overall use of the power distribution cabinet more convenient and maintenance more efficient; 2. When the first heat dissipation blade is closed and the second heat dissipation blade is opened, since the heat in the outer shell is accumulated above the outer shell, in order to effectively dissipate the heat above the outer shell from the second heat dissipation blade, a plurality of fans are installed on the top of the outer shell. These fans are used to blow the heat on the top of the outer shell downward to the second heat dissipation blade, thereby dissipating the heat in the outer shell from the second heat dissipation blade.

[0029] However, when the fan blows the heat downward, it will blow the heat to the bottom of the shell, and thus cannot effectively ensure that the heat is dissipated from the second heat dissipation blade. Therefore, when it is necessary to dissipate the heat from the second heat dissipation blade, the partition is rotated from the vertical state to the horizontal state, and the shell is divided into two independent chambers by the partition. When the fan blows the heat above the shell downward, the partition effectively prevents the heat from being blown to the bottom of the shell by the fan; 3. Set the waterproof trough at an angle so that after rainwater falls on the bottom of the trough, it can slide directly out from the bottom of the trough, thereby effectively preventing rainwater from gathering on the waterproof trough, making it easier for staff to maintain and clean the distribution cabinet.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0033] Example: The present application embodiment discloses a power distribution cabinet that is easy to maintain efficiently. Figure 1 , including a shell 1, which is in an "I"-shaped structure as a whole, and corresponding electrical equipment is installed inside the shell 1, and these equipment are installed at the bottom of the shell 1. The left and right sides of the top of the shell 1 are both provided with first heat dissipation holes 2 in the vertical direction, and the heat gathered above the shell 1 is dissipated to the outside of the shell 1 through the first heat dissipation holes 2 on both sides. The left and right sides of the middle part of the shell 1 are both sunken with waterproof grooves 3 in the direction of approaching each other, and the side walls of the waterproof grooves 3 are provided with second heat dissipation holes 4 in the vertical direction, and the second heat dissipation holes 4 are also used to dissipate the heat in the power distribution cabinet to the outside of the shell 1.

[0034] Specifically, refer to Figure 1 , a plurality of first heat dissipation blades 5 are evenly distributed at intervals along the vertical direction at the first heat dissipation hole 2, and a first driving assembly is added on the side wall of the housing 1, and the first driving assembly is used to drive the first heat dissipation blades 5 to rotate at the first heat dissipation hole 2. At the same time, a plurality of second heat dissipation blades 6 are evenly distributed at intervals along the vertical direction at the second heat dissipation hole 4, and a second driving assembly is added on the side wall of the housing 1, and the second driving assembly is used to drive the second heat dissipation blades 6 to rotate at the second heat dissipation hole 4.

[0035] Under normal conditions, when it is not raining, these first heat dissipation blades 5 are in an open state, and the second heat dissipation blades 6 are in a closed state. In this state, the heat in the shell 1 is still dissipated through the first heat dissipation holes 2. When it rains, the first drive component drives the corresponding first heat dissipation blades 5 to rotate so that they gradually close, and at the same time, the second drive component drives the corresponding second heat dissipation blades 6 to rotate so that they gradually open. The purpose of this is to transfer the heat dissipation in the shell 1 from the first heat dissipation holes 2 to the second heat dissipation holes 4. When the first heat dissipation holes 2 are closed, the heat in the shell 1 can still be dissipated through the second heat dissipation holes 4, and thus will not affect the normal heat dissipation requirements inside the shell 1.

[0036] At the same time, since the second heat dissipation hole 4 is provided at the waterproof groove 3 of the housing 1, the waterproof groove 3 can effectively block rainwater outside the second heat dissipation hole 4 when the second heat dissipation hole 4 is dissipating heat, thereby effectively ensuring that the power distribution cabinet is effectively waterproof without affecting heat dissipation. The use of the waterproof groove 3 can effectively improve the overall waterproof effect of the power distribution cabinet, thereby effectively reducing the number of times the staff performs maintenance on the power distribution cabinet, making the overall use of the power distribution cabinet more convenient and maintenance more efficient.

[0037] Specifically, the presence of the waterproof groove 3 allows a buffer zone to be reserved between the second heat dissipation hole 4 and the outermost side of the housing 1. This buffer zone allows rainwater to gradually slide downwards due to gravity during the process of being blown by the wind, and eventually falls on the bottom of the waterproof groove 3, rather than being directly blown into the second heat dissipation hole 4 by the wind, thereby effectively preventing rainwater from accumulating in the power distribution cabinet through the waterproof groove 3. When the power distribution cabinet is used outdoors in thunderstorm weather, the waterproof performance of the power distribution cabinet can be effectively increased without affecting the heat dissipation of the power distribution cabinet, thereby effectively improving the safety of the outdoor power distribution cabinet during use, and effectively reducing the number of times the staff performs maintenance on the power distribution cabinet, thereby making the overall use of the power distribution cabinet more convenient and maintenance more efficient.

[0038] In this embodiment, the bottom of the waterproof groove 3 is tilted, and the end close to the second heat dissipation hole 4 is at a high position, and the end away from the second heat dissipation hole 4 is at a low position. The waterproof groove 3 is tilted so that after rainwater falls on the bottom of the waterproof groove 3, it can directly slide out from the bottom of the waterproof groove 3, thereby effectively preventing rainwater from gathering on the waterproof groove 3, and making it easier for staff to maintain and clean the power distribution cabinet.

[0039] Specifically, refer to Figure 2 and Figure 3The first driving assembly includes a first knob 7, a first driving gear 8 and a first driven gear 9, and the first driving gear 8 and the first driven gear 9 are both arranged vertically. A first support box 10 is fastened to the side wall of the housing 1 by fastening bolts, and the first knob 7 is rotatably mounted on the outside of the first support box 10. A corresponding rotating shaft is installed between the first knob 7 and the first driving gear 8 in the horizontal direction, and the first knob 7 drives the first driving gear 8 to rotate synchronously through the rotating shaft while rotating. The first driven gear 9 is meshed and connected with the first driving gear 8, and the first driving gear 8 drives the first driven gear 9 to rotate synchronously while rotating. The first driven gear 9 and the top first heat dissipation fan blade 5 are also connected by a corresponding rotating shaft. During the rotation process, the first driven gear 9 drives the first heat dissipation fan blade 5 to rotate through the corresponding rotating shaft, thereby realizing the adjustment of the angle of the first heat dissipation fan blade 5.

[0040] Specifically, when it is rainy and the first heat dissipation blade 5 needs to be closed, the first knob 7 is turned to drive the first driving gear 8 to rotate. During the rotation, the first driving gear 8 drives the first driven gear 9 to rotate, and then the top first heat dissipation blade 5 is driven to rotate through the first driven gear 9 until the first heat dissipation blade 5 is closed.

[0041] The specific rotation angle of the first heat dissipation blade 5, that is, the specific closing degree of the first heat dissipation blade 5 can be adjusted accordingly according to the amount of external rainfall or the strength of wind. For example, when the external rainfall and wind are heavy, the first heat dissipation blade 5 can be directly rotated to a fully closed state; when the rainfall and wind are light, it is only necessary to appropriately rotate the first heat dissipation blade 5 to convert it from a fully open state to a semi-closed state.

[0042] Further, refer to Figure 2 and Figure 3 , a first pulley 11 is installed in the vertical direction on the side of the first heat dissipation blade 5 away from the first knob 7, and the first pulley 11 is fastened to the side wall of the housing 1. A first roller 12 is installed in the vertical direction on the side of the first heat dissipation blades 5 away from the first knob 7, and these first rollers 12 are sleeved in the first pulley 11, and the first rollers 12 and the corresponding first heat dissipation blades 5 are connected through corresponding rotating shafts. When the top first heat dissipation blade 5 is driven by the first driven gear 9 to rotate, the first heat dissipation blade 5 drives the first pulley 11 to rotate through the corresponding first roller 12, and then drives the remaining first heat dissipation blades 5 below to rotate accordingly through the first pulley 11, and then the top first heat dissipation blade 5 can synchronously drive the remaining first heat dissipation blades 5 to rotate together during the rotation process through the first pulley 11 and the first roller 12, so that the adjustment of these first heat dissipation blades 5 is more efficient.

[0043] Specifically, refer to Figure 1 , Figure 2 as well as Figure 3 The second driving assembly includes a second knob 13, a second driving gear 14 and a second driven gear 15, and the second driving gear 14 and the second driven gear 15 are both arranged vertically. A second support box 16 is fastened to the side wall of the housing 1 by fastening bolts, and the second knob 13 is rotatably mounted on the outside of the second support box 16. A corresponding rotating shaft is installed between the second knob 13 and the second driving gear 14 in the horizontal direction, and the second knob 13 drives the second driving gear 14 to rotate synchronously through the rotating shaft while rotating. The second driven gear 15 and the second driving gear 14 are meshed and connected, and the second driving gear 14 drives the second driven gear 15 to rotate synchronously while rotating. The second driven gear 15 and the second heat dissipation blade 6 at the top are also connected by a corresponding rotating shaft. During the rotation process, the second driven gear 15 drives the second heat dissipation blade 6 to rotate through the corresponding rotating shaft, thereby realizing the adjustment of the angle of the second heat dissipation blade 6.

[0044] Specifically, when it is rainy and the second heat dissipation blade 6 needs to be opened, the second knob 13 is turned to drive the second driving gear 14 to rotate. During the rotation, the second driving gear 14 drives the second driven gear 15 to rotate, and then the second driven gear 15 drives the top second heat dissipation blade 6 to rotate until the second heat dissipation blade 6 is opened.

[0045] When the outside rainfall and wind are heavy, since the first heat dissipation blade 5 is in a completely closed state, the second heat dissipation blade 6 can be directly rotated to a fully open state; when the rainfall and wind are light, since the first heat dissipation blade 5 is in a semi-closed state, the heat above the distribution cabinet can still be dissipated through the first heat dissipation blade 5, so it is only necessary to properly rotate the second heat dissipation blade 6 to make it in a semi-open state.

[0046] Further, refer to Figure 1 , Figure 2 as well as Figure 3, a second pulley 17 is installed in the vertical direction on the side of the second heat dissipation blade 6 away from the second knob 13, and the second pulley 17 is fastened to the side wall of the housing 1. A second roller 18 is installed in the vertical direction on the side of the plurality of second heat dissipation blades 6 away from the second knob 13, and these second rollers 18 are sleeved in the second pulley 17, and the second rollers 18 and the corresponding second heat dissipation blades 6 are connected through corresponding rotating shafts. When the top second heat dissipation blade 6 rotates under the drive of the second driven gear 15, the second heat dissipation blade 6 drives the second pulley 17 to rotate through the corresponding second roller 18, and then drives the remaining second heat dissipation blades 6 below to rotate accordingly through the second pulley 17, and then the top second heat dissipation blade 6 can synchronously drive the remaining second heat dissipation blades 6 to rotate together through the second pulley 17 and the second roller 18 during the rotation process, so that the adjustment of these second heat dissipation blades 6 is more efficient.

[0047] Further, refer to Figure 1 and Figure 4 A partition 19 is horizontally provided at the second heat dissipation hole 4 in the power distribution cabinet. The partition 19 is in a rectangular shape as a whole. One end of the partition 19 is hingedly connected to the inner wall of the shell 1, so that the partition 19 can rotate in the shell 1.

[0048] When the first heat dissipation blades 5 are closed and the second heat dissipation blades 6 are opened, since the heat in the outer shell 1 is accumulated above the outer shell 1, in order to effectively dissipate the heat above the outer shell 1 from the second heat dissipation blades 6, a plurality of fans are installed on the top of the outer shell 1. These fans are used to blow the heat on the top of the outer shell 1 downward to the second heat dissipation blades 6, thereby dissipating the heat in the outer shell 1 from the second heat dissipation blades 6.

[0049] However, when the fan blows the heat downward, it will blow the heat to the bottom of the housing 1, and thus cannot effectively ensure that the heat is dissipated from the second heat dissipation blades 6. Therefore, when it is necessary to dissipate the heat from the second heat dissipation blades 6, the partition 19 is rotated from a vertical state to a horizontal state, and the housing 1 is divided into two independent chambers by the partition 19. When the fan blows the heat above the housing 1 downward, the partition 19 effectively prevents the heat from being blown to the bottom of the housing 1 by the fan.

[0050] In this embodiment, the partition 19 is located in the middle of the second heat dissipation hole 4, which enables the fan to blow the heat to the upper half of the second heat dissipation hole 4 for dissipation. At the same time, the heat continuously generated by the electrical equipment under the outer shell 1 can be dissipated from the lower half of the second heat dissipation hole 4, thereby effectively ensuring the overall heat dissipation efficiency of the distribution cabinet.

[0051] Further, refer to Figure 1 and Figure 4The inner wall of the housing 1 is provided with a snap ring 20 for limiting the end of the partition 19. When the partition 19 is rotated to a horizontal state, the end of the partition 19 is inserted into the snap ring 20, and the snap ring 20 is used to stably limit the partition 19. The snap ring 20 is made of an elastic material, which facilitates the insertion or removal of the end of the partition 19.

[0052] The implementation principle of a power distribution cabinet that is easy to maintain efficiently in the embodiment of the present application is: Under normal conditions, when it is not raining, these first heat dissipation blades 5 are in an open state, and the second heat dissipation blades 6 are in a closed state. In this state, the heat in the shell 1 is still dissipated through the first heat dissipation holes 2. When it rains, the first drive component drives the corresponding first heat dissipation blades 5 to rotate so that they are gradually closed, and at the same time, the second drive component drives the corresponding second heat dissipation blades 6 to rotate so that they are gradually opened. The purpose of this is to transfer the heat dissipation in the shell 1 from the first heat dissipation holes 2 to the second heat dissipation holes 4. When the first heat dissipation holes 2 are closed, the heat in the shell 1 can still be dissipated through the second heat dissipation holes 4, and thus will not affect the normal heat dissipation requirements inside the shell 1.

[0053] At the same time, since the second heat dissipation hole 4 is provided at the waterproof groove 3 of the housing 1, the waterproof groove 3 can effectively block rainwater outside the second heat dissipation hole 4 when the second heat dissipation hole 4 is dissipating heat, thereby effectively ensuring that the power distribution cabinet is effectively waterproof without affecting heat dissipation. The use of the waterproof groove 3 can effectively improve the overall waterproof effect of the power distribution cabinet, thereby effectively reducing the number of times the staff performs maintenance on the power distribution cabinet, making the overall use of the power distribution cabinet more convenient and maintenance more efficient.

[0054] Specifically, the presence of the waterproof groove 3 allows a buffer zone to be reserved between the second heat dissipation hole 4 and the outermost side of the housing 1. This buffer zone allows rainwater to gradually slide downwards due to gravity during the process of being blown by the wind, and eventually falls on the bottom of the waterproof groove 3, rather than being directly blown into the second heat dissipation hole 4 by the wind, thereby effectively preventing rainwater from accumulating in the power distribution cabinet through the waterproof groove 3. When the power distribution cabinet is used outdoors in thunderstorm weather, the waterproof performance of the power distribution cabinet can be effectively increased without affecting the heat dissipation of the power distribution cabinet, thereby effectively improving the safety of the outdoor power distribution cabinet during use, and effectively reducing the number of times the staff performs maintenance on the power distribution cabinet, thereby making the overall use of the power distribution cabinet more convenient and maintenance more efficient.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
