[0022] See also Figure 1-5As shown, an outdoor frequency conversion control cabinet includes a work box body 1. The work box body 1 can facilitate the staff to control the frequency and voltage of the power supply. A vent 2 is opened on one side of the work box body 1. The vent 2 can dissipate heat and cool the work box body 1 when it is working. The bottom of the work box body 1 is bolted with a base shell 3. One side of the base shell 3 is provided with a connecting block 4. The number of the connecting blocks 4 is four and they are symmetrically designed with the central axis of the base shell 3. Under the action of the connecting block 4, the base shell 3 can be fixed in the working position. The inner cavity of the base shell 3 is provided with a roller 5. The roller 5 passes through the bottom of the base shell 3 and does not contact the bottom of the base shell 3. Under the action of the roller 5, it is convenient for the staff to move the work box body 1. The bottom of the threaded rod 7 is rotatably connected to the inner cavity of the base shell 3, and the bottom of the threaded rod 7 is rotatably connected to the inner cavity of the base shell 3. The inner cavity of the base shell 3 is slidably connected to a movable plate 9, and the inner cavity of the movable plate 9 is threadedly connected to the surface of the threaded rod 7. The bottom of the movable plate 9 is fixedly connected to the top of the roller 5. With the cooperation of the stepping motor 6 and the threaded rod 7, the movable plate 9 can be moved in the inner cavity of the base shell 3, and the roller 5 is driven to move downward, so that the roller 5 can move the work box body 1, which reduces the labor of the staff and is convenient for operation. The staff moves the frequency conversion control cabinet to the working position. The inner cavity of the base shell 3 is fixedly connected with a guide rod 10. The surface of the guide rod 10 is slidably connected to the inner cavity of the movable plate 9. Under the action of the guide rod 10, the movable plate 9 can be effectively prevented from being offset during movement, thereby increasing the practicality of the frequency conversion control cabinet. The surface of the working box body 1 is provided with a rain shield assembly 11. The surface of the working box body 1 is bolted with a fixed shell 12. The inner cavity of the fixed shell 12 is bolted with an electric telescopic rod 13. The output shaft of the electric telescopic rod 13 is fixedly connected with a mounting block 14. The rain shield assembly 11 consists of a winding shell, a torsion spring, a winding roller and a rain shield cloth wound on the surface of the winding roller. The surface of the mounting block 14 slides with the inner cavity of the fixed shell 12 The other end of the mounting block 14 is bolted to one side of the rain shield cloth of the rain shield assembly 11, and with the cooperation of the electric telescopic rod 13 and the mounting block 14, the rain shield cloth of the rain shield assembly 11 can be stretched up and down on one side of the working box body 1, so that the rain shield cloth of the rain shield assembly 11 can shield the vent 2 from rain, effectively preventing rainwater from entering the interior of the working box body 1 through the vent 2 and causing damage to the device, thereby improving the service life of the frequency conversion control cabinet. A guide mechanism 15 is provided on one side of the rain shield assembly 11. Under the action of the guide mechanism 15, the rain shield assembly 11 can be effectively prevented from positional displacement during movement, thereby increasing the stability of the rain shield assembly 11 and improving the stability of the frequency conversion control cabinet.

[0023] The guide mechanism 15 includes a mounting shell 151, one side of the mounting shell 151 is bolted to the surface of the working box body 1, the inner cavity of the mounting shell 151 is fixedly connected to a fixing rod 152, the surface of the fixing rod 152 is slidably connected to a guide block 153, the surface of the guide block 153 is slidably connected to the inner cavity of the mounting shell 151, and one side of the guide block 153 is bolted to one side of the rain shield component 11. With the cooperation of the electric telescopic rod 13 and the mounting block 14, the rain shield component 11 can drive the guide block 153 to move on the surface of the fixing rod 152, and with the cooperation of the mounting shell 151, the rain shield component 11 is effectively prevented from positional displacement during movement, thereby increasing the stability of the rain shield component 11 and thus improving the stability of the frequency conversion control cabinet.

[0024] Working principle: First, when the staff needs to move the frequency conversion control cabinet to the working position, the stepper motor 6 drives the threaded rod 7 to rotate. The threaded rod 7 moves the multiple rollers 5 downward at the same time through the moving plate 9, and with the cooperation of the guide rod 10, the movement of the moving plate 9 can be made more stable. When the roller 5 has finished moving, the staff moves the limit rod 82 to the inside of the corresponding hole 83, which effectively prevents the threaded rod 7 from rotating. Then the staff fixes the frequency conversion control cabinet in the working position with the bolt through the connecting block 4. When it rains, Under the action of the electric telescopic rod 13, the mounting block 14 can be moved downward in the inner cavity of the fixed shell 12, and the mounting block 14 drives the rain shield cloth in the rain shield assembly 11 to move downward. At the same time, the rain shield assembly 11 drives the guide block 153 to move on the surface of the fixed rod 152, and under the action of the mounting shell 151, the movement of the rain shield assembly 11 can be made more stable, allowing the rain shield assembly 11 to block the rain from the vent 2. When the rain stops, under the action of the torsion spring and the winding roller in the rain shield assembly 11, the rain shield cloth of the rain shield assembly can be wound upward.
