Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figures 1-5, an embodiment provided by the present invention: a control box for a substation, comprising a control box shell 1 and an adjustment device 2, the adjustment device 2 is slidably connected to the inside of the control box shell 1, and the control box The inner bottom surface of the housing 1 is fixedly connected with a slide rail 5 , the inner two sides of the control box housing 1 are evenly provided with a first heat dissipation hole 3 , and the top surface of the slide rail 5 is provided with a second chute 6 , which is located on the inner side of the slide rail 5 . There is a first chute 4, a suspension device 8 is fixedly installed inside the adjustment device 2, a sliding device 7 is fixedly connected to the upper and lower ends of the suspension device 8, and a first connecting rod 10 is arranged inside the sliding device 7. The first connecting rod The two ends of the 10 are fixedly connected with a slider 11, the bottom center of the slider 11 is slidably connected with a pulley 12, the center of the first connecting rod 10 is rotatably connected with a positioning screw 9, and the bottom of the positioning screw 9 is fixedly connected with a squeeze plate 13, A mounting plate 15 is fixedly installed inside the suspension device 8 , the two sides of the mounting plate 15 are fixedly connected with support rods 14 , the center of the support rod 14 is movably connected with a pull rod 16 , and the surface of the mounting plate 15 is evenly provided with second cooling holes 17 .

The lengths of the first chute 4 and the second chute 6 are kept the same, and are located at the center of the top surface and the center of the inner side of the slide rail 5, so that the first connecting rod 10 and the supporting rod 14 pass through the first chute 4 and the second The sliding groove 6 maintains the consistency of lateral sliding inside the sliding rail 5 to avoid the unstable state of the first connecting rod 10 and the support rod 14 during the sliding process. The first connecting rod 10 is fixedly connected to the side center of the slider 11, And the support rod 14 is fixedly connected to the center of the top surface of the slider 11, so that the first connecting rod 10 and the supporting rod 14 can always be kept in a horizontal and vertical state during the sliding process, thereby effectively improving the first connecting rod 10 and the supporting rod. 14 The fluency when sliding laterally inside the slide rail 5, the two ends of the pull rod 16 are pivotally connected to the center of the support rod 14 through hinges, and the pull rod 16 can rotate 90 degrees up and down through the hinge as the axis under the action of external force, and The length of the tie rod 16 is equal to half of the length of the suspension device 8 , so that the bottom of the tie rod 16 is effectively at the same height as the bottom of the suspension device 8 in the vertical state, so as to prevent workers from being affected by the installation of electronic components on the front of the mounting plate 15 . Due to the interference of the pull rod 16, the distance between the two end faces of the suspension device 8 and the inner two sides of the control box shell 1 is ten centimeters, so that when the adjusting device 2 slides laterally inside the control box shell 1, there will be no mutual friction. In the case of interference sliding, the sliding block 11 slides inside the sliding rail 5 through the pulley 12, so that when the sliding block 11 slides on the inner bottom surface of the sliding rail 5, the rotation of the pulley 12 can improve the adjustment device 2 in the control box shell 1. The smoothness of the internal sliding prevents the slider 11 from being stuck when sliding inside the slide rail 5 .

Working principle: When the control box fails, maintenance workers are required to check and maintain the control box. During maintenance, the control box door needs to be opened first, and then the positioning screw 9 is rotated by external force and the bottom end is driven through the center of the first connecting rod 10. The squeeze plate 13 is far away from the inner bottom surface of the control box shell 1, so that the squeeze plate 13 loses the downward pressing force, and then the pull rod 16 is rotated upward by 90 degrees with the hinge as the axis under the action of the external force, and then the pull rod 16 is moved upward by the external force. Pulled out, when the pull rod 16 moves outward, it will drive the support rods 14 connected at both ends to move, and when the support rod 14 moves, it will drive the sliders 11 at both ends to slide laterally inside the slide rail 5, and the sliders 11 are in When moving, the bottom pulley 12 slides on the inner bottom surface of the slide rail 5, and when the pulley 12 rotates, the smoothness of the lateral sliding of the adjusting device 2 inside the control box housing 1 can be improved, until the pulley 12 slides inside the slide rail 5 to another. At this time, the adjusting device 2 slides to the outermost end of the slide rail 5, and then the pull-down rod 16 is rotated downward by 90 degrees with the hinge as the axis under the action of external force, and then the set screw 9 is rotated by the external force and passes through the first connecting rod 10. The center drives the extruding disc 13 at the bottom end to extrude the inner bottom surface of the control box shell 1, thereby fixing the changed position of the adjusting device 2, which is convenient for maintenance workers to check and maintain, and effectively avoids the maintenance workers in the process of inspection and maintenance. The electric shock accident occurs due to the narrow space. After the maintenance worker completes the operation, turn the positioning screw 9 again to drive the bottom squeeze plate 13 away from the inner bottom surface of the control box shell 1, so that the squeeze plate loses downward pressure, and then under the action of external force The pull-down rod 16 rotates upwards 90 degrees with the hinge as the axis, and then pushes the pull-rod 16 with an external force to drive the two ends of the adjustment device 2 to slide inside the slide rail 5 until the slide block 11 slides back to the original position, and then under the action of external force The pull-down rod 16 rotates downwards 90 degrees with the hinge as the axis, and finally rotates the positioning screw 9 to drive the squeeze plate 13 to squeeze the inner bottom surface of the control box shell 1, thereby fixing the position of the adjustment device 2 after maintenance.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention , alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
