A guide block 23 is slidably connected to the outer side of the guide rod 25. One side of the guide block 23 is fixedly connected to the cabinet 1. A rotating wheel 7 is rotatably connected to the top of the base 3. The bottom end of the rotating wheel 7 extends into the interior of the adjustment groove 5 and is fixedly connected to the threaded rod 6.

[0021] By rotating the wheel 7, the threaded rod 6 drives the adjusting block 8 to rotate between the inner walls of the adjusting groove 5. At the same time, the guide rod 25 inside the guide groove 24 guides the guide block 23, thereby driving the cabinet 1 to move between the inner walls of the base 3, thus improving the installation flexibility of the frequency converter control cabinet.

[0022] like Figures 1-4 As shown, the locking structure includes a lock groove 16, a limit rod 17 is fixedly connected between the inner walls of the lock groove 16, a slider 18 is slidably connected to the outer side of the limit rod 17, a toggle block 20 and a locking block 26 are fixedly connected to both sides of the slider 18 respectively, a locking groove 22 is opened on one side inside the cabinet 1, the inner side of the locking groove 22 contacts the locking block 26, and a return spring 19 is provided between the slider 18 and the inner side of the lock groove 16, the return spring 19 is located on the outer side of the limit rod 17.

[0023] By pushing the lever 20, the slider 18 is moved to the outside of the limit rod 17, and the return spring 19 (made of high carbon steel) is pressed inside the lock groove 16. Then, the locking block 26 is moved out of the inside of the locking groove 22, thereby releasing the cabinet door 2 from the lock.

[0024] The spring force of the reset spring 19 pushes the slider 18 to move between the inner walls of the locking groove 16, and at the same time drives the locking block 26 to lock into the inside of the locking groove 22, thereby completing the fixation of the cabinet door 2 and improving the convenience of maintenance of the frequency converter control cabinet.

[0025] like Figures 1-4As shown, the cleaning structure includes a connecting block 9, which is fixedly connected to one side of the cabinet door 2. A sliding groove 10 is provided on the top of the connecting block 9, which passes through the connecting block 9.

This achieves the adjustment of the installation height of the cabinet 1 and establishes an electrical connection between the cabinet 1 and the slag conveying bucket elevator. After installation, the slider 18 is pushed by the spring force of the return spring 19 to move between the inner walls of the locking groove 16, and at the same time, the locking block 26 is driven into the inside of the locking groove 22, thereby fixing the cabinet door 2 to one side of the cabinet body 1, thus protecting the internal equipment of the cabinet body 1. When the internal equipment of the cabinet body 1 is operating, a lot of heat is generated, which can be discharged through the heat dissipation groove 11. The dustproof plate 12 prevents dust from contaminating the inside of the cabinet body 1. Then, by pushing the handle 15, the limiting block 14 is moved on the top of the connecting block 9, which causes the brush 13 to move between the inner walls of the sliding groove 10. At the same time, the brush 13 moves on one side of the dustproof plate 12, thereby removing the dust on the dustproof plate 12, further ensuring the heat dissipation effect of the heat dissipation groove 11.

[0028] When maintenance is performed inside the cabinet 1, the slider 18 can be moved outside the limit rod 17 by pushing the lever 20, and the return spring 19 is pressed inside the lock groove 16. Then, the locking block 26 is moved out of the groove 22, thereby releasing the cabinet door 2 from the lock. Then, the cabinet door 2 is pulled to rotate outside the fixing rod 21 between the two fixing blocks 4, thereby locking the cabinet door 2 and performing maintenance, thus completing the use of the frequency converter control cabinet.
