The following describes a one-time use procedure of the present invention with reference to the accompanying drawings:
when the wire in the control box needs to be bunched, firstly, the adjusting bolt 11 in the bunching mechanism 6 is screwed anticlockwise, at the moment, the rotation motion of the adjusting bolt 11 can be converted into the translation of the posture adjusting and adapting plate 10, the distance between the posture adjusting and adapting plate 10 and the back plate of the box body 1 is increased, the bunching cover plate 9 is gradually far away from the back plate of the box body 1, then the wire in the control box is stroked and moved to the inner side of the bunching cover plate 9, then the adjusting bolt 11 is screwed clockwise, at the moment, the distance between the posture adjusting and adapting plate 10 and the back plate of the box body 1 is reduced until the bunching cover plate 9 is attached to the back plate of the box body 1 again, and therefore the wire is limited between the bunching cover plate 9 and the back plate of the box body 1, and the bunching work of the wire is finished at the moment.
After the operation panel 5 is used, in order to prevent dust and water from entering the operation panel 5, the servo motor control button 22 is pressed down, the servo motor 16 is started to drive the screw rod 17 to rotate anticlockwise, at the moment, the rotary motion of the screw rod 17 can be converted into downward linear motion of the screw slider 18, and then the screw slider 18 drives the protective cover 14 to synchronously move downwards until the bottom opening of the protective cover 14 is in abutting contact with the cover opening closing plate 15, so that the operation panel 5 is completely closed on the protective cover 14. When the operation panel 5 is needed to be used next time, the servo motor control button 22 is pressed, the servo motor 16 is started, the screw rod 17 is driven to rotate clockwise, and the protective cover 14 is driven to move upwards through the screw slider 18 until the operation panel 5 is completely separated from the shielding of the protective cover 14, and the operation panel 5 can be used normally at the moment.
When the humidity in the environment where the control box is located is too high, the interior of the control box needs to be subjected to moisture-proof treatment, the box door 2 is firstly opened, then the gripping handle 29 on the drying box 24 is pinched, the drying box 24 is lifted upwards with force, the positioning lug 27 on the drying box 24 is separated from the positioning hole 26 on the drying box positioning frame 25, then the drying box 24 is removed from the control box, the drying agent is placed in the drying box 24 outside the control box, the drying box 24 filled with the drying agent is then sent back to the drying box positioning frame 25 in the control box, and the positioning lug 27 on the drying box 24 is inserted into the positioning hole 26 on the drying box positioning frame 25, so that the installation and the positioning of the drying box 24 are realized. When the door 2 is closed, moisture in the control box can be absorbed by the drying agent through the hollowed-out holes 28 on the box body surface of the drying box 24, so that the purpose of reducing the humidity in the control box is achieved.
The embodiments are not intended to limit the scope of the invention, but rather are intended to cover all equivalent implementations or modifications that can be made without departing from the scope of the invention.
