[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0020] like Figure 1As shown, a frequency converter mounting bracket device in an electric cabinet comprises an electrical control box frame 1, a frequency converter mounting bracket body 4 and an electrical control box mounting plate 6 located at the upper rear side of the frequency converter mounting bracket body 4 are fixedly connected to the electrical control box frame 1, a frequency converter unit 5 is placed on the frequency converter mounting bracket body 4, and the rear side of the frequency converter unit 5 is fixedly connected to the electrical control box mounting plate 6;

[0021] By installing the inverter unit 5 on the inverter mounting bracket body 4, the inverter mounting bracket body 4 bears the main weight of the inverter unit 5, and then the inverter unit 5 is auxiliary supported by the electrical control box mounting plate 6, the weight of the inverter unit 5 borne at the same position of the electrical control box can be dispersed, thereby increasing the stability and firmness of the electrical control box.

[0022] And, if Figure 1-2 As shown, in order to allow the inverter mounting bracket body 4 to better bear the weight of the inverter unit 5, the lower part of the inverter mounting bracket body 4 and the lower part of the electrical control box frame 1 are fixedly connected. At this time, the force borne by the inverter mounting bracket body 4 can be directly transmitted to the lower part of the electrical control box frame 1, and directly transmitted to the ground through the electrical control box frame 1, so that it has better load-bearing performance.

[0023] Among them, Figure 1-2 As shown, the fixing method between the electrical control box frame 1 and the inverter mounting bracket body 4 is preferably screw connection, and the electrical control box mounting plate 6 and the inverter unit 5 are connected by screws. The fixing method is relatively simple, detachable, and relatively stable after fixing.

[0024] like Figure 2-3 As shown, in order to allow the weight of the inverter unit 5 to be concentrated on the inverter mounting bracket body 4, the technical solution improves the screw connection method between the inverter unit 5 and the electrical control box mounting plate 6. Specifically, a connecting plate is fixedly connected to the rear side of the inverter unit 5, and a screw groove 8 is provided on the connecting plate. The screw groove 8 is a vertically arranged through groove, and a locking screw 7 is installed inside the screw groove 8. A screw hole is provided on the electrical control box mounting plate 6, and one end of the locking screw 7 is threadedly connected to the inside of the screw hole. At this time, the locking screw 7 only limits the forward and backward movement of the inverter unit 5, and the downward kinetic energy of the inverter unit 5 is mainly borne by the inverter mounting bracket body 4.

[0025] like Figure 1 As shown, in order to improve the protection effect of the inverter unit 5, the outer side of the electrical control box frame 1 is fixedly connected with an electrical control box shell 2, so that the outer side of the electrical control box frame 1 can form a sealed shell to protect the inverter unit 5.

[0026] Furthermore, in order to better hoist the electrical control box frame 1 , a hoisting device connector 3 is fixedly connected to the upper side of the electrical control box frame 1 , and a hoisting device can be connected through the hoisting device connector 3 to hoist the electrical control box frame 1 .

[0027] The working principle of the utility model is as follows: before the frequency converter unit 5 is installed on the electrical control box frame 1, the frequency converter mounting bracket body 4 needs to be placed on the electrical control box frame 1, and the approximate position of the frequency converter mounting bracket body 4 is preliminarily determined according to the size of the frequency converter unit 5, and then the frequency converter unit 5 is hoisted into the electrical control box frame 1 by auxiliary tools, and the frequency converter unit 5 is placed on the frequency converter mounting bracket body 4. At this time, the frequency converter unit 5 fits with the electrical control box mounting plate 6, and the frequency converter mounting bracket body 4 is fixed to the electrical control box frame 1 with screws, and the frequency converter unit 5 is fixed to the electrical control box mounting plate 6 with screws;

[0028] By installing the inverter unit 5 on the inverter mounting bracket body 4, the main weight of the inverter unit 5 can be borne by the inverter mounting bracket body 4, and then the inverter unit 5 is auxiliary supported by the electrical control box mounting plate 6. The weight of the inverter unit 5 borne at the same position of the electrical control box can be dispersed, thereby increasing the stability and firmness of the electrical control box. The installation of the inverter unit 5 is simpler, saving time and effort. The electrical control box mounting plate 6 only serves as an auxiliary support and does not bear the weight of the inverter unit 5. It is not easy to be damaged during transportation and installation.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
