[0030] A method for using a photovoltaic power distribution cabinet with a heat dissipation function, the steps are as follows:

[0031] Step 1: When the temperature inside the power distribution cabinet is high, start the servo motor, which drives the lead screw to rotate, and the guide rod limits the movable plate to facilitate the lifting and movement of the movable plate. The movement of the movable plate drives the U-shaped plate to move, and the U-shaped plate also drives the gear to move. The gear and the rack mesh, so that the fan blade part rotates to blow air when it rises, and the heat is discharged from the air outlet slot on the top. When the fan blade part descends, air is extracted, and the heat is discharged from the heat dissipation holes on both sides;

[0032] Step 2: When the U-shaped plate rises, both ends will squeeze the inclined surface of the mounting block. Since the total elastic force of multiple springs 2 is greater than the elastic force of springs 1 and 3, the U-shaped plate first drives the mounting block to rise, and the mounting block drives the vertical rod to rise. The mounting block compresses spring 1, and the vertical rod rises to squeeze the bottom inclined surface of the extrusion rod 1. The limiting ring limits the extrusion rod 1, so that the extrusion rod 1 stretches the spring 3, and the extrusion rod 1 is pressed into the heat dissipation hole. The extrusion rod 1 can drive other extrusion rods 2 to be pressed into the heat dissipation hole through the connecting plate;

[0033] Step 3: After the spring 1 is compressed to the limit, the vertical rod no longer rises. At this time, the installation block stretches the spring 2, so that the installation block makes way for the U-shaped plate. The U-shaped plate rises smoothly and separates from the installation block. Then the installation block and the vertical rod are reset, thereby completing the extrusion and cleaning of the heat dissipation holes in the same row. Then the U-shaped plate continues to rise, and the heat dissipation holes in other rows can be cleaned, reducing the blockage of the heat dissipation holes. A stopper is provided on the top of the vertical rod, and the vertical rod will not fall. When the U-shaped plate falls later, the installation block is directly squeezed and makes way, and the heat dissipation holes are not cleaned.

[0034] Step 4: When the moving plate rises, the moving plate drives the pushing plate to rise. The rising pushing plate will squeeze the contact plate. The contact plate compresses the auxiliary spring, and the contact plate acts on the flip plate. The flip plate is subjected to force and will rotate and unfold on the contact plate. The two flip plates stretch the reset springs, which makes it easier for the cleaning roller to move and scrape the filter, reducing the blockage of the filter.

[0035] Compared with the prior art, the invention has the following beneficial effects: a heat dissipation component is provided, and the servo motor is started to facilitate the rotation of the fan blade part to blow air, thereby achieving large-area blowing and heat dissipation from top to bottom, and by squeezing and cleaning a single row of heat dissipation holes, the heat dissipation holes will not be blocked in a large area, thereby reducing the influence on ventilation and heat dissipation of the heat dissipation holes, thereby improving the heat dissipation effect and heat dissipation efficiency;

[0036] 1. A heat dissipation component is provided. When the temperature inside the power distribution cabinet is high, the servo motor is started, and the servo motor drives the lead screw to rotate. The guide rod limits the movable plate to facilitate the lifting and lowering of the movable plate. The movement of the movable plate drives the U-shaped plate to move, and the U-shaped plate also drives the gear to move. The gear is meshed with the rack, so that the fan blade part rotates to blow air when it rises, and the heat is discharged from the air outlet slot on the top, and the fan blade part is sucked when it descends. At this time, the heat is discharged from the heat dissipation holes on both sides, and the two ends of the U-shaped plate will squeeze the inclined surface of the mounting block when it rises. Since the total elastic force of multiple springs 2 is greater than the elastic force of springs 1 and 3, first the U-shaped plate drives the mounting block to rise, and the mounting block drives the vertical rod to rise. The mounting block compresses spring 1, and the vertical rod rises to squeeze the bottom inclined surface of the extrusion rod 1. The limiting ring limits the extrusion rod 1, so that the extrusion rod 1 stretches the spring 3, and the extrusion rod 1 is pressed into the heat dissipation hole. The extrusion rod 1 can drive other extrusion rods 2 to be pressed into the heat dissipation hole through the connecting plate. The spring 1 is compressed After shrinking to the limit, the vertical rod no longer rises, and at this time the mounting block stretches the second spring, so that the mounting block makes way for the U-shaped plate, and the U-shaped plate rises smoothly and separates from the mounting block, and then the mounting block and the vertical rod are reset, thereby completing the extrusion and cleaning of the heat dissipation holes in the same row, and then the U-shaped plate continues to rise, and the heat dissipation holes in other rows can be cleaned, thereby reducing the blockage of the heat dissipation holes, and a stopper is provided on the top of the vertical rod, and the vertical rod will not fall, and when the U-shaped plate subsequently falls, the mounting block is directly squeezed and makes way, and the heat dissipation holes are not cleaned, thereby realizing large-area blowing and heat dissipation from top to bottom, and by squeezing and cleaning a single row of heat dissipation holes, the heat dissipation holes will not be blocked in a large area, reducing the influence on the ventilation and heat dissipation of the heat dissipation holes, and facilitating the extrusion and cleaning of the heat dissipation holes, thereby improving the heat dissipation effect and heat dissipation efficiency, and solving the problem that the heat dissipation effect of blowing air at the top and bottom corners of the power distribution cabinet is relatively general, and as the working time increases, the components at the corners that are not directly blown may still be damaged due to high temperature;

[0037] 2. An auxiliary component is provided. When the moving plate rises, the moving plate drives the pushing plate to rise. The rising of the pushing plate will squeeze the contact plate. The contact plate compresses the auxiliary spring, and the contact plate acts on the flip plate. The flip plate is subjected to force and will rotate and unfold on the contact plate. The two flip plates stretch the reset spring, which is convenient for the cleaning roller to move and scrape the filter, reduces the blockage of the filter, and facilitates the discharge of heat. The auxiliary spring is used for resetting the contact plate, and the reset spring is used for resetting the flip plate. By setting the bottom plate and the top plate, and fixing the bottom plate and the top plate to the inner wall of the distribution cabinet by bolts, it is convenient to disassemble the components between the bottom plate and the top plate as a whole, which is convenient for maintenance and use.

[0062] Embodiment 1: Figure 1-Figure 8 As shown, when the temperature inside the power distribution cabinet 1 is high, by starting the servo motor 82, the servo motor 82 drives the screw rod 83 to rotate, and the guide rod 84 limits the movable plate 86 to facilitate the lifting and lowering movement of the movable plate 86.

[0070] Embodiment 2: Figure 9-11 As shown, when the movable plate 86 rises, the movable plate 86 drives the push plate 91 to rise. The rising of the push plate 91 will squeeze the contact plate 92. The contact plate 92 compresses the auxiliary spring 93, and the contact plate 92 acts on the flip plate 94. The flip plate 94 is subjected to force and will rotate and unfold on the contact plate 92. The two flip plates 94 stretch the reset spring 96, which is convenient for the cleaning roller 95 to move and scrape the filter screen 6, reducing the blockage of the filter screen 6 and facilitating the discharge of heat. The auxiliary spring 93 is used to reset the contact plate 92, and the reset spring 96 is used to reset the flip plate 94.

[0071] Working principle: When using the device, first, Figure 1-Figure 11As shown, when the temperature inside the power distribution cabinet 1 is high, by starting the servo motor 82, the servo motor 82 drives the screw rod 83 to rotate, the moving plate 86 moves to drive the U-shaped plate 87 to move, the gear 89 is meshed with the rack 88, so that the fan blade part 810 rotates to blow air, which is convenient for heat discharge. When the U-shaped plate 87 rises, the two ends will squeeze the inclined surface of the mounting block 815. First, the U-shaped plate 87 drives the mounting block 815 to rise, and the mounting block 815 drives the vertical rod 812 to rise. The vertical rod 812 rises and squeezes the bottom inclined surface of the extrusion rod 1 820, so that the extrusion rod 1 820 is pressed into the heat dissipation hole 7, and the extrusion rod 1 820 drives the other extrusion rod 2 823 to also be pressed into the heat dissipation hole 7. After the spring 1 814 is compressed to the limit, the vertical rod 812 no longer rises, the U-shaped plate 87 rises smoothly and separates from the mounting block 815, completing the extrusion and cleaning of the heat dissipation holes 7 in the same row, and then the U-shaped plate 87 continues to rise to clean the heat dissipation holes 7 in other rows. When the U-shaped plate 87 subsequently descends, the heat dissipation holes 7 are not cleaned, and when the movable plate 86 rises, the movable plate 86 drives the push plate 91 to rise. The rising push plate 91 will squeeze the contact plate 92, and the contact plate 92 compresses the auxiliary spring 93, and the contact plate 92 acts on the flip plate 94. The flip plate 94 is subjected to force and will rotate and unfold on the contact plate 92. The two flip plates 94 stretch the reset spring 96, which is convenient for the cleaning roller 95 to move and scrape the filter screen 6, thereby reducing the blockage of the filter screen 6 and facilitating the discharge of heat.

9. A method for using a photovoltaic power distribution cabinet with heat dissipation function, characterized in that: The photovoltaic power distribution cabinet with heat dissipation function as claimed in claim 8 is used in the following steps: Step 1: When the temperature inside the power distribution cabinet (1) is high, the servo motor (82) is started, the servo motor (82) drives the screw rod (83) to rotate, and the guide rod (84) limits the movable plate (86) to facilitate the lifting and lowering movement of the movable plate (86). The movement of the movable plate (86) drives the U-shaped plate (87) to move, and the U-shaped plate (87) also drives the gear (89) to move. The gear (89) and the rack (88) are meshed, so that the fan blade part (810) rotates to blow air when it rises, and the heat is discharged from the air outlet slot (5) at the top. When the fan blade part (810) descends, air is sucked out, and the heat is discharged from the heat dissipation holes (7) on both sides. Step 2: When the U-shaped plate (87) rises, both ends will squeeze the inclined surface of the installation block (815). Since the total elastic force of the plurality of springs 2 (817) is greater than the elastic force of the springs 1 (814) and 3 (819), the U-shaped plate (87) first drives the installation block (815) to rise, and the installation block (815) drives the vertical rod (812) to rise. The installation block (815) compresses the spring 1 (814), and the vertical rod (812) rises to squeeze the bottom inclined surface of the extrusion rod 1 (820). The limiting ring (821) limits the extrusion rod 1 (820), so that the extrusion rod 1 (820) stretches the spring 3 (819), and the extrusion rod 1 (820) is pressed into the heat dissipation hole (7). The extrusion rod 1 (820) can drive the other extrusion rods 2 (823) to be pressed into the heat dissipation hole (7) through the connecting plate (822); Step 3: After the spring 1 (814) is compressed to the limit, the vertical rod (812) no longer rises. At this time, the mounting block (815) stretches the spring 2 (817), so that the mounting block (815) gives way to the U-shaped plate (87). The U-shaped plate (87) rises smoothly and separates from the mounting block (815). Then the mounting block (815) and the vertical rod (812) are reset, thereby completing the extrusion and cleaning of the heat dissipation holes (7) in the same row. Then the U-shaped plate (87) continues to rise, and the heat dissipation holes (7) in other rows can be cleaned, thereby reducing the blockage of the heat dissipation holes (7). A stopper is provided at the top of the vertical rod (812), so that the vertical rod (812) will not fall. When the U-shaped plate (87) falls later, the mounting block (815) is directly squeezed and gives way, and the heat dissipation holes (7) are not cleaned. Step 4: When the moving plate (86) rises, the moving plate (86) drives the pushing plate (91) to rise. The rising pushing plate (91) squeezes the contact plate (92). The contact plate (92) compresses the auxiliary spring (93). The contact plate (92) acts on the flip plate (94). The flip plate (94) is subjected to force and rotates and unfolds on the contact plate (92). The two flip plates (94) stretch the reset spring (96), which facilitates the cleaning roller (95) to move and scrape the filter screen (6), thereby reducing the blockage of the filter screen (6).
