[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0026] like Figures 1 to 5 As shown in one embodiment of this utility model, a frequency converter support device is provided. The frequency converter includes a frequency converter body 11, and a plurality of fixing ears 12 are provided on the frequency converter body 11 for easy fixing of the frequency converter body 11. The frequency converter support device includes a fixing plate 21 provided on the back of the frequency converter body 11. The fixing plate 21 has a first mounting hole that matches the fixing ears 12 and a plurality of second mounting holes 22. Fixing bolts are provided between the fixing ears 12 and the first mounting holes to facilitate fixing the frequency converter body 11 to the fixing plate 21. Fixing bolts are provided in the second mounting holes 22 to facilitate fixing the fixing plate 21 to the frequency converter cabinet, thereby fixing the frequency converter body 11 to the frequency converter cabinet. Alternatively, the fixing plate 21 can be directly fixed in a designated position.
[0027] The bottom end of the fixed plate 21 is provided with a support platform located below the inverter body 11 and away from the inverter body 11. The support platform includes a first support plate 31 fixedly connected to the bottom end of the fixed plate 21, a second support plate 32 provided on the first support plate 31, and a third support plate 33 provided on the second support plate 32.
[0028] Specifically, when maintenance is required on the inverter body 11 located at a high position, the inverter body 11 is removed from the fixing plate 21 and placed on the support platform for maintenance. This facilitates maintenance, and the disassembled parts can also be placed on the support platform to prevent them from being discarded. The first support plate 31 has multiple wire holes 311, which allow cables to pass through and connect to the inverter body 11.
[0029] Multiple hinges 34 are provided between the first support plate 31 and the second support plate 32, and multiple hinges 34 are provided between the second support plate 32 and the third support plate 33. That is, the second support plate 32 is hinged to the first support plate 31, and the third support plate 33 is hinged to the second support plate 32. When the second support plate 32 and the third support plate 33 are placed flat, the second support plate 32 can rest against the first support plate 31, and the third support plate 33 can rest against the second support plate 32. The first support plate 31 is fixedly connected to the bottom end of the fixing plate 21, and the fixing plate 21 is fixedly connected to the inverter cabinet, ensuring the stability of the inverter body 11 during maintenance.
[0030] Furthermore, the second support plate 32 can rotate on the first support plate 31, and the third support plate 33 can rotate on the second support plate 32. The second support plate 32 can rotate upward to a position perpendicular to the first support plate 31, and the third support plate 33 can rotate to a position parallel to the first support plate 31. That is, when the support platform is not in use, the second support plate 32 and the third support plate 33 can be rotated to a position close to the inverter body 11, saving space and preventing interference with the opening and closing of the inverter cabinet door.
[0031] The third support plate 33 has a first fixing hole 331, and the upper end of the fixing plate 21 has a second fixing hole 332 that matches the first fixing hole 331. A locking bolt 333 is threaded between the first fixing hole 331 and the second fixing hole 332. The third support plate 33 is provided with a handle 334. The third support plate 33 can be rotated to the upper end of the fixing plate 21, which can fix the third support plate 33 to the upper end of the fixing plate 21. The second support plate 32 is located between the first support plate 31 and the third support plate 33. The handle 334 facilitates the movement of the entire device.
[0032] The second support plate 32 is provided with baffles 321 on its side end face. The baffles 321 can shield the inverter body 11 under maintenance and prevent the inverter body 11 or disassembled parts from falling off the support platform.
[0033] The baffle 321 is matched with the side end of the inverter body 11, the first support plate 31 is matched with the bottom end face of the inverter body 11, the second support plate 32 is matched with the front end face of the inverter body 11, and the third support plate 33 is matched with the upper end face of the inverter body 11.
[0034] Specifically, the first support plate 31 can cover the bottom surface of the inverter body 11, the second support plate 32 can cover the front surface of the inverter body 11, the third support plate 33 can cover the upper surface of the inverter body 11, and the baffle 321 can cover the side surface of the inverter body 11. That is, when the position of the inverter body 11 needs to be moved, it can play a protective role for the inverter body 11.
[0035] The baffle 321 has multiple heat dissipation holes 322. When there is no suitable installation location for the inverter cabinet due to space limitations, the fixing plate 21, the first support plate 31, the second support plate 32, the third support plate 33 and the baffle 321 can act as an inverter cabinet to protect the inverter body 11. The heat dissipation holes 322 do not affect the heat dissipation of the inverter body 11.
[0036] When using, refer to Figures 1-5 As shown, the inverter body 11 is mounted on the fixing plate 21, which is installed inside the inverter cabinet. When it is necessary to maintain the inverter body 11 at a high position, the cabinet door is opened, the inverter body 11 is removed from the fixing plate 21, and the inverter body 11 is placed on the support platform for maintenance.
[0037] Compared with the prior art, the inverter support device of this utility model can provide a flat maintenance platform for inverters when they are being repaired at high locations, which facilitates maintenance.
