[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First, open the cabinet door and rotate it sixty degrees. Due to the influence of the length of the pull rope, the pull rope is just taut when the cabinet door rotates sixty degrees. At this time, when rain drops on the surface of the cabinet door and splashes due to the cabinet door being opened, since the awning cloth has not been rolled up, the rain splashed on the surface of the cabinet door will be blocked by the awning cloth and will not enter the interior of the electrical cabinet body. When the cabinet door continues to be rotated, since the pull rope is already taut, it will gradually drive the awning cloth to reel in. When rain drops on the outer surface of the cabinet door and splashes, the cabinet door will not enter the electrical cabinet body because the rotation range is too large and the cabinet door is far away from the electrical cabinet body. When rain drops on the inner surface of the cabinet door and splashes, since the awning cloth has not been completely rolled up, it can block the rain dripping on the inside of the cabinet door, thereby avoiding the situation where rain drops on the side surface of the cabinet door and splashes into the interior of the electrical cabinet body when the cabinet door is opened to inspect the electrical cabinet body on rainy days, thereby protecting the operator.

The positioning block 11 corresponds to the positioning groove 8 and is movably clamped. The two ends of the first spring 6 are respectively fixed on the side surfaces of the baffle 10 fixed to the adjacent support rod 5.

[0036] There are multiple groups of awnings 2, which are distributed in an array. The two ends of the awnings 2 are respectively fixed to the outer surfaces of two adjacent groups of support rods 5. The support plate 12 is fixed to the outer surface of the end of the support rod 5, and the support plate 12 is 'L' shaped.

[0037] A positioning hole 18 is formed on the outer surface of the end of the support rod 5, and an annular groove 19 is formed on the inner wall of the positioning hole 18. An annular block 22 is fixed to the outer surface of one end of the rotating shaft 15. The rotating shaft 15 corresponds to the positioning hole 18 and is movably fixed, and the annular block 22 corresponds to the annular groove 19 and is movably fixed.

[0038] The diameter of the rotating shaft 15 is the same as the inner diameter of the positioning hole 18 , the diameter of the annular block 22 is the same as the inner diameter of the annular groove 19 , the diameter of the annular block 22 is larger than the diameter of the rotating shaft 15 , and a movable sleeve 14 is movably sleeved on the outer surface of the rotating shaft 15 .

[0039] A limiting groove 21 is formed on the outer surface of the rotating shaft 15 , a limiting block 20 is fixed on the inner wall of the movable sleeve 14 , the limiting block 20 corresponds to the limiting groove 21 and is movably arranged, and the side surface of the supporting plate 12 is located between the roller 7 and the gear 13 .

[0040] A second spring 16 is movably sleeved on the outer surface of the movable sleeve 14, and the second spring 16 is located between the support plate 12 and the gear 13. The diameter of the roller 7 is larger than the diameter of the gear 13, and the distance between the roller 7 and the end of the electrical cabinet body 1 is smaller than the distance between the end of the side surface of the support plate 12 and the end of the electrical cabinet body 1.

[0041] A stopper 23 and a fixing plate 25 are fixed to the surface of the support plate 12 near the gear 13 . The stopper 23 is L-shaped. A support shaft 26 is fixed to the inner wall surface of the stopper 23 . The limiting plate 17 is movably sleeved on the outer surface of the support shaft 26 .

[0042] One side surface of the limit plate 17 is in contact with the inner surface of the stopper 23 , and the other side surface of the limit plate 17 is fixed with a third spring 24 , the end of the third spring 24 is fixed to the side surface of the fixing plate 25 , and the limit plate 17 and the gear 13 are opposite and movably arranged.

[0043] In actual use, the cabinet door 4 is an insulating cabinet door with an insulating film fixed on its outer surface. When the electrical cabinet body 1 needs to be opened for maintenance on a rainy day, the cabinet door 4 is first opened and rotated sixty degrees. Due to the influence of the length of the pull rope 3, the pull rope 3 is just tightened when the cabinet door 4 rotates sixty degrees. At this time, when raindrops fall on the surface of the cabinet door 4 due to the cabinet door 4 being opened and splashing, since the awning 2 is not rolled up, the rainwater splashed on the surface of the cabinet door 4 will be blocked by the awning 2 and will not enter the interior of the electrical cabinet body 1. When the cabinet door 4 continues to be rotated, since the pull rope 3 is already tightened, it will gradually drive the awning 2 to be rolled up. When raindrops fall on the surface of the cabinet door 4 on the outside and splashes, the cabinet door 4 will be away from the electrical cabinet body due to the excessive rotation amplitude. 1 is far away so that rain will not enter the electrical cabinet body 1. When rain drops on the surface of the cabinet door 4 near the inner side and splashes, the tarpaulin 2 is not completely rolled up, so it can block the rain dropping on the inner side of the cabinet door 4, thereby avoiding the situation that rain drops on the side surface of the cabinet door 4 and splashes into the interior of the electrical cabinet body 1 when the cabinet door 4 is opened to repair the electrical cabinet body 1 on rainy days, which plays a protective role for operators. When the tarpaulin 2 is rolled up by the pull rope 3, only the outermost support rod 5 is pulled, and due to the elasticity of the first spring 6, the outermost support rod 5 will evenly distribute the pulling force to other support rods 5, so that each group of support rods 5 is subjected to the same force, so multiple groups of tarpaulins 2 can be rolled up and closed at the same time. At the same time, when the support rod 5 moves inward to drive the awning 2 to be rolled up, the support rod 5 moves along the positioning block 11 to drive the roller 7 to rotate clockwise on the inner wall surface of the electrical cabinet body 1, and the clockwise rotation of the roller 7 drives the gear 13 to rotate clockwise, and the fixed plate 25 is located on one side of the clockwise rotation direction of the gear 13, and the fixed plate 25 is not in contact with the side surface of the limiting plate 17, and there is a certain distance between the two, so the clockwise rotation of the gear 13 can drive the limiting plate 17 to swing counterclockwise around the support shaft 26, so the support rod 5 moves inward to drive the awning 2 to be rolled up without being hindered, and when the support rod 5 moves outward to drive the awning 2 to be reset, since the gear 13 rotates counterclockwise at this time, The limit plate 17 will swing clockwise, and the stop block 23 fits with the side surface of the limit plate 17, so the clockwise swinging direction of the limit plate 17 will be blocked by the stop block 23, so that the gear 13 cannot rotate, and the roller 7 cannot rotate, thereby avoiding the phenomenon that the tarpaulin 2 is pushed to reset due to the elastic reset of the first spring 6 during maintenance, thereby achieving the stability of the tarpaulin 2 during maintenance; and when the maintenance is completed and the tarpaulin 2 needs to be restored, it is only necessary to pull the roller 7 outward to drive the gear 13 to move outward along the axis of the rotating shaft 15 and squeeze the second spring 16 to separate the gear 13 from the limit plate 17. At this time, the gear 13 will not be limited by the limit plate 17, and the gear 13 can be rotated counterclockwise, thereby realizing the restoration of the tarpaulin 2.
