Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 The present invention provides the following technical solution:

[0030] Example 1: To address the problems existing in the use of existing prefabricated substations, this example provides a prefabricated substation with a three-dimensional flow guiding channel, comprising a substation body 1 and a protective door 2 hinged to the front of the substation body 1; a flow guiding mechanism is provided at the lower center of the back of the substation body 1, and the flow guiding mechanism includes a flow guiding box 3, with the top left and right sides of the flow guiding box 3 connected to the bottom of the flow guiding channel body 4; the flow guiding mechanism includes flow guiding slots 7, which are opened at equal angles inside the flow guiding box 3, and the flow guiding box 3 communicates with the internal space of the substation body 1 through the flow guiding slots 7.

[0031] The flow guiding mechanism includes a flow guiding turbine fan assembly 8, which is rotatably installed at the center of the flow guiding box 3. The flow guiding turbine fan assembly 8 is used to guide the substation body 1 and the flow guiding channel body 4 through the connection with negative pressure.

[0032] like Figures 1-2 , Figure 7 As shown, the substation body 1 houses the electrical components, while the protective door 2 on the front provides a closed protection for the substation body 1. During heat dissipation, the flow guide box 3 installed on the back of the substation body 1 operates. The flow guide turbine fan assembly 8 inside the flow guide box 3 rotates, creating a negative pressure state in the flow guide box 3 to expel air from the outside. At the same time, the flow guide slot 7 inside the flow guide box 3 is connected to the substation body 1 to assist in the expulsion of hot air from the substation body 1 and prevent blockage of the flow guide box 3.

[0033] Example 2: To address the problems existing in the use of existing prefabricated substations, this example employs the following technical solution: A diversion mechanism is provided on both the left and right sides of the substation body 1. This diversion mechanism includes a closed partition box 5, and a docking valve plate 6 is slidably installed inside the closed partition box 5. The diversion mechanism includes heat dissipation slots 9, which are equidistantly located on the left and right sides above the substation body 1. These symmetrically located heat dissipation slots 9 are sealed and isolated by the external closed partition box 5. The docking valve plate 6, included in the diversion mechanism, is arranged in a hollow structure. Diversion slots 10 are equidistantly located on the side of the docking valve plate 6 closest to the substation body 1, and the hollow docking valve plate 6 allows for the circulation of internal and external air through the diversion slots 10.

[0034] The diversion mechanism includes a linkage bracket 11, the front end of which is fixedly connected to the back of the left and right docking valve plates 6. A lifting screw 12 is threaded through the middle of the symmetrically arranged linkage bracket 11. The lifting screw 12 is rotatably mounted on the back of the substation body 1 via a bearing. The lifting screw 12 is driven by the servo motor of the diversion box 3 to raise and lower the docking valve plates 6. The diversion mechanism includes a diversion channel 13, the top end of which is connected to the bottom end of the left and right docking valve plates 6. The bottom end of the diversion channel 13 is slidably sleeved on the top end of the diversion channel body 4. The diversion channel body 4 under negative pressure achieves heat dissipation inside the substation body 1 through the diversion channel 13 and the docking valve plates 6.

[0035] like Figures 3-6 As shown, the enclosed partition box 5 included in the diversion mechanism covers and seals the heat dissipation slots 9 opened on the left and right sides of the substation body 1. At the same time, the servo motor installed inside the diversion box 3 drives the external lifting screw 12 to rotate, so that the linkage bracket 11 threadedly connected to the lifting screw 12 is driven to slide upward. At the same time, the linkage bracket 11 drives the docking valve plate 6 fixedly connected to the outer end to move upward into the interior of the enclosed partition box 5, so that the diversion slots 10 opened inside the docking valve plate 6 correspond to the heat dissipation slots 9 on the left and right sides of the substation body 1.
