[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present application solves the problem that the distribution cabinet can usually only be inspected by opening the cabinet doors on both sides of the front side, which is prone to crowding and collision when multiple workers are inspecting the distribution cabinet, resulting in low inspection efficiency, by providing a control mechanism, a control mechanism body, a hydraulic push rod, a push-pull assembly, a distribution cabinet outer frame, a distribution cabinet top cover and a component assembly cabinet.

The two component assembly cabinets 6 each include an assembly cabinet body 61, and the front and rear sides of the bottoms of the two assembly cabinet bodies 61 close to each other are fixedly connected with assembly cabinet sliders 62. The outer walls of the two groups of assembly cabinet sliders 62 are respectively slidably connected to the two sides of the inner walls of the two base slide grooves 12, and the front and rear sides of the inner sides of the two assembly cabinet bodies 61 are respectively fixedly connected to the outer sides of the left and right groups of L-shaped push-pull rods 5117;

[0036] When inspecting the inner wall of the outer frame 2 of the power distribution cabinet or installing the wiring assembly, the staff can open the cabinet door 22 on the front side of the outer frame 2 of the power distribution cabinet. If the installation or inspection workload is large and requires the cooperation of multiple staff, the two hydraulic push rods 514 on the inner wall of the outer frame 511 of the control mechanism should be started. After the hydraulic push rods 514 are activated, the two push plates 518 will be pulled inward. The movement of the push plates 518 will drive the outer sliding rods 5111 and the push-pull rods 5112 on the front and rear sides to move inward. As the two sets of push-pull rods 5112 move inward, the rotating rod 5114 is pulled, thereby causing the two-way hinged rod 5115 to rotate on the inner wall of the control mechanism slide plate 5119, and the L-shaped push-pull rod 5117 is moved through the second rotating rod 5116;

[0037] At the same time, when the two push plates 518 move inward, they will drive the two groups of hinge blocks 521 to move inward, which will prompt the intersection rod 522 to rotate and change the angle, push the two-way intersection block 523 to move upward, and then move the distribution cabinet top cover 3 toward the top. In this way, the two sides of the bottom of the distribution cabinet top cover 3 are pulled out from the inner walls on the left and right sides of the distribution cabinet outer frame body 21, so that the left and right sides of the distribution cabinet outer frame body 21 are opened. At this time, the two groups of L-shaped push-pull rods 5117 move outward, pulling the two assembled cabinet bodies 61, causing them to move outward and move out from the left and right sides of the outer wall of the distribution cabinet outer frame body 21.

[0038] See also Figure 9-10The shielding cover 4 includes a shielding cover control mechanism 41, and the left and right ends of the top of the shielding cover control mechanism 41 are respectively fixedly connected with a shielding cover body 42. The shielding cover control mechanism 41 includes four bottom blocks 411, and the bottoms of the four bottom blocks 411 are respectively fixedly connected to the four sides of the top of the top cover 3 of the power distribution cabinet. The tops of the four bottom blocks 411 are all fixedly connected with a C-shaped frame 412, and the inner walls of the four C-shaped frames 412 are all slidably connected with a rack rod 419, and the inner walls of the four C-shaped frames 412 are rotatably connected to the side away from the rack rod 419. Gear 418, the outer walls of the four gears 418 are meshed with one side of the rack rod 419, the tops of the four C-shaped frames 412 are fixedly connected with push rod sliding groove blocks 413, the inner sides of the left and right rack rods 419 extend to the outer walls of the C-shaped frame 412 and the tops are fixedly connected with push rod connecting blocks 4112, the outer sides of the left and right push rod connecting blocks 4112 are fixedly connected with push rods 4113, the outer walls of the left and right push rods 4113 are respectively slidably connected to the inner sides of the left and right push rod sliding groove blocks 413, and the left and right push rods One end of the slide block 413 away from the push rod connecting block 4112 is fixedly connected to the left and right sides of the inner wall of the shielding cover body 42, and the two rack rods 419 on the left side are fixedly connected to the extension rod 4110 on the side away from the C-shaped frame 412. The inner sides of the two extension rods 4110 are fixedly connected to the inner racks 4111. The two extension rods 4110 are extended to the inner walls of the two C-shaped frames 412 on the right side on one side, and the two inner racks 4111 are connected to the inner walls of the two C-shaped frames 412 on the right side. The outer wall of the gear 418 is meshed with the outer wall of the gear 418, the inner sides of the front and rear two groups of C-shaped frames 412 are fixedly connected with the vertical plates 414, the right bottom of the left vertical plate 414 is fixedly connected with the dual-axis motor 415, the front and rear output ends of the dual-axis motor 415 are fixedly connected with the conical teeth 416, the outer walls of the two conical teeth 416 are meshed with the second conical teeth 417, the tops of the two second conical teeth 417 extend to the inner walls of the two C-shaped frames 412 on the left side respectively and are fixedly connected to the bottom of the gear 418 on the inner walls of the two C-shaped frames 412 on the left side;

[0039] When the outer frame 2 of the power distribution cabinet needs to be opened on rainy or snowy days, in order to prevent rainwater from entering the inner part of the outer frame 2 of the power distribution cabinet and damaging the components installed on the component assembly cabinet 6, the dual-axis motor 415 is started at this time, and the rotation of the motor drives the conical gear 416 to rotate, thereby rotating the second conical gear 417, and the rotation of the second conical gear 417 drives the gear 418 in the two left C-shaped frames 412 to rotate. Since the gear 418 is engaged with the rack rod 419, the rack rod 419 slides accordingly, and drives the push rod 4113 through the push rod connecting block 4112 to push the shielding cover body 42 to move. When the two rack rods 419 move, they drive the extension rod 4110 to move and engage the gear 418 on the inner wall of the right C-shaped frame 412 through the inner rack 4111 on the inner side of the extension rod 4110 to rotate, thereby causing the two shielding cover bodies 42 to move in opposite directions;

[0040] As the push rod 4113 moves, the shielding cover body 42 is pushed open. Due to the ingenious design of the shielding cover control mechanism 41, even in bad weather conditions, it can ensure that the components on the component assembly cabinet 6 inside the power distribution cabinet are protected from rain or snow. In addition, when the shielding cover needs to be closed, the double-axis motor 415 only needs to be operated in reverse to achieve the closing of the shielding cover.

[0041] The shielding cover control mechanism 41 of the power distribution cabinet not only improves the protection performance of the power distribution cabinet, but also simplifies the operation process through automatic control, so that the power distribution cabinet can maintain a good working state under various weather conditions. This power distribution cabinet for power engineering construction based on the smart grid is not only suitable for severe weather environments, but also provides a strong guarantee for the stable operation of the power system.

[0042] Working principle: When inspecting the inner wall of the distribution cabinet outer frame 2 or installing the wiring components, the staff can open the cabinet door 22 on the front side of the distribution cabinet outer frame 2. If the installation or maintenance workload is large and requires the cooperation of multiple staff members, the two hydraulic push rods 514 on the inner wall of the control mechanism outer frame 511 should be started. After the hydraulic push rods 514 are activated, the two push plates 518 will be pulled inward. The movement of the push plates 518 will drive the outer sliding rods 5111 and the push-pull rods 5112 on the front and rear sides to move inward. As the two sets of push-pull rods 5112 move inward, the rotating rod 5114 is pulled, thereby causing the two-way hinged rod 5115 to rotate on the inner wall of the control mechanism slide plate 5119. The two rotating rods 5116 and the L-shaped push-pull rods 5117 are moved. At the same time, when the two push plates 518 move inward, they will drive the two sets of hinge blocks 521 to move inward, which will cause the intersection rod 522 to rotate and change the angle, push the two-way intersection block 523 to move upward, and then move the top cover 3 of the distribution cabinet toward the top. In this way, the two sides of the bottom of the top cover 3 of the distribution cabinet are pulled out from the inner walls on the left and right sides of the main body 21 of the outer frame of the distribution cabinet, so that the left and right sides of the main body 21 of the outer frame of the distribution cabinet are opened. At this time, the two sets of L-shaped push-pull rods 5117 move outward, pull the two assembled cabinet bodies 61, so that they move outward and move out from the left and right sides of the outer wall of the main body 21 of the outer frame of the distribution cabinet;

[0043] When the outer frame 2 of the power distribution cabinet needs to be opened on rainy or snowy days, in order to prevent rainwater from entering the inner part of the outer frame 2 of the power distribution cabinet and damaging the components installed on the component assembly cabinet 6, the dual-axis motor 415 is started at this time, and the rotation of the motor drives the conical gear 416 to rotate, thereby rotating the second conical gear 417, and the rotation of the second conical gear 417 drives the gear 418 in the two C-shaped frames 412 on the left to rotate. Since the gear 418 is engaged with the rack rod 419, the rack rod 419 slides accordingly, and drives the push rod 4113 through the push rod connecting block 4112 to push the shielding cover body 42 to move. When the two rack rods 4 As 19 moves, it drives the extension rod 4110 to move and engages the gear 418 on the inner wall of the right C-shaped frame 412 through the inner rack 4111 on the inner side of the extension rod 4110, thereby causing the two shielding cover bodies 42 to move in opposite directions. As the push rod 4113 moves, the shielding cover bodies 42 are pushed open. Due to the ingenious design of the shielding cover control mechanism 41, even in severe weather conditions, it can ensure that the components on the internal component assembly cabinet 6 of the distribution cabinet are protected from rain or snow. In addition, when it is necessary to close the shielding cover, it is only necessary to operate the dual-axis motor 415 in reverse to achieve the closing of the shielding cover.
