[0029] See also Figure 1-Figure 6In order to facilitate the installation and fixation of the electronic component main body 4 separately to avoid mutual interference, and to facilitate the individual removal and maintenance operation when a fault occurs, a mounting frame 5 of a mounting mechanism is welded inside the control cabinet main body 1 (the number of mounting mechanisms corresponds to the number of electronic component main bodies 4, and the figure only shows a schematic diagram of two groups, and the number is arranged and assembled according to the actual number of electronic component main bodies 4), and a mounting rail 13 with a rectangular cross-section is opened in the mounting frame 5, and the two ends of the electronic component main body 4 can be bonded, bolted or welded to fix a mounting block 15 that is convenient for sliding in the mounting rail 13, and the mounting rail 13 is larger than the mounting block 15, which can facilitate the upward lifting operation of the mounting block 15 in the mounting rail 13, and in order to facilitate the positioning operation after installation, a positioning groove 14 is equidistantly opened at the bottom end of the mounting rail 13, and a positioning block 16 that is plugged and positioned with the positioning groove 14 is welded in the middle of the bottom end of the mounting block 15, and in order to ensure the positioning effect during use, an elastic pad can be bonded to the inner wall of the positioning groove 14 to ensure the firmness of the plugging with the positioning block 16.

[0030] See also Figure 1-Figure 6 In order to guide and organize the wires electrically connected to the electronic component body 4 and avoid the entanglement of the wires when the electronic component body 4 is moved out for maintenance, a mounting plate 7 of a guide winding mechanism is welded at the bottom of the control cabinet body 1 (the number of guide winding mechanisms corresponds to the number of mounting mechanisms), and a reserved hole is provided at the bottom of the control cabinet body 1 for convenient insertion of the wires, and a winding cavity 17 of a reset component is provided inside the mounting plate 7, and a rotating shaft 19 is connected to the winding cavity 17 through a volute spring 18. The rotating shaft 19 is located between two adjacent mounting plates 7 and a rope reel 20 is provided on the outside, which can facilitate the winding and winding of the wires (the winding can be one to two turns, which does not affect the removal of the electronic component body 4 for maintenance, and can also avoid safety hazards such as strong inductive reactance or heat caused by too many turns of winding).

[0031] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0032] In summary, with the aid of the above technical solution of the utility model, when the electronic component body 4 is installed in use, the mounting block 15 is aligned with the mounting rail 13 of the mounting frame 5, the mounting block 15 is lifted upward to make it fit with the top of the inner side of the mounting rail 13, and pushed into the control cabinet body 1, and it slides in the mounting rail 13, and after being adjusted to the installation position, it is released and moves downward under the action of its own gravity, and then the positioning block 16 at the bottom end of the mounting block 15 enters the positioning groove 14, and the insertion and limiting are performed, thereby completing the installation of the electronic component body 4. When wiring, the wires are inserted into the control cabinet body 1 through the reserved holes, and then wound through the rope reel 20 (one to two turns are reserved to facilitate the subsequent removal of the electronic component body 4), and then electrically connected to the electronic component body 4 to complete the assembly operation. When in use, the temperature sensor 12 detects the internal temperature. When the temperature rises, the electric push rod 11 can be extended to move the adjustment plate 9 upward in the empty slot 8. The through hole 10 corresponds to the dust-proof heat dissipation net 6, and cooperates with the internal heat dissipation device to facilitate ventilation and heat dissipation. When the temperature is relatively low When the electronic component 4 to be repaired is removed, the positioning block 16 leaves the positioning groove 14 by lifting it upwards, and then the positioning block 16 is pulled outwards. At this time, the mounting block 15 slides in the mounting rail 13 to remove it, and then the wire is pulled, the rope reel 20 and the rotating shaft 19 rotate, the wire is released, and the volute spring 18 rotates to rewind and store it. Potential energy, after being moved out and put down, the positioning block 16 enters the positioning groove 14, and temporarily positions the electronic component body 4 that needs to be repaired, which can facilitate the staff to perform maintenance and other operations. After completion, by lifting the electronic component body 4 upward, the positioning block 16 leaves the positioning groove 14 and pushes inward (repeat the above installation process to complete the installation of the electronic component body 4), and at the same time, with the potential energy of the vortex spring 18 when it is rolled up, the rotating shaft 19 and the rope reel 20 are rotated and reset, so that the wires can be rolled up to avoid entanglement and the like.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
