DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 The utility model provides a technical solution: a power distribution cabinet for a thermal power plant, comprising a cabinet body 1, and also comprising:

[0031] A cooling bottom plate 2 is arranged in the cabinet 1. The cooling bottom plate 2 is I-shaped and hollow. An air outlet 3 is arranged at the connection between the top of the cabinet 1 and the cooling bottom plate 2.

[0032] The cooling device 4 is arranged at the bottom of the cabinet 1 and is used to input cooling air into the hollow position of the cooling bottom plate 2;

[0033] Multiple groups of mounting slot plates 5 are evenly mounted on the inner side of the cooling base plate 2 from top to bottom through multiple groups of cards and components 6, and are used to install various components required in the cabinet 1 and the wiring between the components;

[0034] A plurality of air outlet holes 7 are evenly arranged on the cooling bottom plate 2;

[0035] The communication hole 8 is arranged on the mounting slot plate 5 and is communicated with the air outlet hole 7 .

[0036] Among them, the cooling base plate 2 is slidably set in the cabinet 1, and a limiting slide plate 21 for the sliding setting of the cooling base plate 2 is provided in the cabinet 1. An installation cabinet door 11 is provided on one side of the cabinet 1 for the cooling base plate 2 to slide into the cabinet 1 for installation and to limit one side of the cooling base plate 2.

[0037] At the same time, the card and piece 6 include:

[0038] The engaging block 61 is fixedly arranged on the inner side of the mounting slot plate 5;

[0039] The fixed strip plate 62 is fixedly arranged on the mounting slot plate 5 and is located below the air outlet 7. The fixed strip plate 62 is provided with a first slot 63 for the lower end of the locking block 61 to be locked in.

[0040] The sliding strip plate 64 is slidably arranged above the air outlet hole 7 of the mounting slot plate 5, and the sliding strip plate 64 is provided with a second slot 65 for the upper end of the locking block 61 to be locked in;

[0041] The limiting sliding parts 66 are disposed at both ends of the sliding strip 64 and are used for the sliding strip 64 to slide up and down.

[0042] In addition, the limiting sliding part 66 includes sliders 661 fixedly arranged at both ends of the sliding strip 64, and the cooling bottom plate 2 is provided with a fixed limiting plate 662 for limiting the sliders 661 to slide up and down;

[0043] When installing the cooling base plate 2, the installation cabinet door 11 can be opened, and then the installation base plate can be pushed into the cabinet 1 from there, that is, the side of the cabinet 1. Before the cooling base plate 2 is installed and pushed in, the various components installed on the cooling base plate 2 near the inner end can be installed thereon first, and the various components on the cooling base plate 2 near the cabinet door can be installed after the cooling base plate 2 is installed. In this way, various components can be installed on both sides of the cooling base plate 2, which greatly utilizes the internal space of the cabinet 1 and also increases the intervals between various components, so that when cooling is needed in the later stage, the cooling efficiency of various components can be accelerated.

[0044] A pull ring 663 for facilitating pulling of the sliding strip 64 is provided at the middle of the sliding strip 64 .

[0045] Finally, the mounting slot plate 5 is in a hollow strip shape, so that the air outlet holes 7 arranged on both sides of the cooling bottom plate 2 can enter the hollow part of the mounting slot plate 5 from the hollow position, so that the cold air can stay in the hollow part of the mounting slot plate 5 to cool down various components installed on the mounting slot plate 5. At the same time, the cold air in the cooling bottom plate 2 can also enter the hollow position of the mounting slot plate 5 through the air outlet holes 7 at the middle position and the connecting hole 8, further improving the cooling efficiency;

[0046] When it is necessary to cool down the cabinet 1, the air-conditioning device 4 works, and inputs cold air from the bottom of the cabinet 1 to the hollow position of the cooling base plate 2, so that the hot air in the cooling base plate 2 is discharged from the air outlet 3 at the upper end of the cabinet 1. At the same time, during the cold air input process, the cold air will pass through the air outlet holes 7 and the connecting holes 8 on the cooling base plate 2, and will also enter the hollow position of the mounting slot plate 5, so as to first cool down the components installed on the mounting slot plate 5 which are prone to fire and burnout due to high temperature, and then the cold air is slowly transferred to other positions in the cabinet 1, and then cools down other positions inside the cabinet 1, so as to better prevent the components from burning out or even catching fire due to high temperature, so as to better prevent the distribution cabinet from catching fire and burning out due to high temperature.
