Description

Technical Field

[0001] The present application relates to the technical field of substation air ducts, and specifically to an air duct structure for a substation. Background Art

[0002] The air duct of a substation usually refers to the facilities used for ventilation and heat dissipation, especially for transformers and other high-power electrical equipment. In a substation, since the equipment will generate a lot of heat during long-term operation, air ducts are needed to dissipate heat and maintain the normal operating temperature of the equipment.

[0003] Existing substation air ducts are usually composed of filters and grilles. Dust or debris will adhere to the filter net in this combination, affecting the heat dissipation efficiency. Rainwater can easily enter the substation with the wind, damaging electrical components and easily causing safety accidents. Therefore, this application proposes a substation air duct structure to solve such problems. Summary of the invention

[0010] Compared with the prior art: In this application, the cover plate is rotatably connected to the receiving groove, so as to accommodate the filter screen inside the substation, thereby preventing rainwater from entering the substation with the wind on rainy days. And through the setting of the steel brush, during the process that the cover plate drives the filter screen to rotate into the substation, the steel brush can brush off the sundries or dust on the filter screen, improving the air permeability of the filter screen. There is also a locking group provided, which is convenient for workers to fix the movement of the filter screen, the cover plate and the support plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Specifically, by the rotational connection between the cover plate 3 and the receiving groove 2, the filter screen 6 can be received in the substation, thereby preventing rainwater from entering the substation with the wind on rainy days, and by the provision of the steel brush 12, when the cover plate 3 drives the filter screen 6 to rotate and enter the substation, the steel brush 12 can brush off the debris or dust on the filter screen 6, thereby improving the air permeability of the filter screen 6. A locking group is also provided to facilitate workers to move and fix the filter screen 6, the cover plate 3 and the support plate 5.

[0020] Furthermore, the locking group is mainly composed of a pull plate 8, a spring 13, an insert rod 14, a baffle 15 and a mounting groove 17. A mounting groove 17 is arranged on the side wall of the square vent, a spring 13 is arranged in the mounting groove 17, an insert rod 14 is arranged on the inner side of the spring 13, a baffle 15 is arranged on the insert rod 14, and one end of the baffle 15 is in contact with the spring 13, one end of the insert rod 14 passes through the mounting plate 1 and is connected with the pull plate 8, and the other end of the insert rod 14 is inserted into the socket 16 of the support plate 5.

[0021] Specifically, the baffle 15 limits the spring 13 in the installation groove 17 .

[0022] Furthermore, the pull plate 8 is T-shaped and connected to the insertion rod 14 via threads.

[0023] The T-shaped pull plate 8 is rotated 90 degrees counterclockwise, and the pull plate 8 is pulled, so that the pull plate 8 drives the insertion rod 14 and the baffle 15 to squeeze the spring 13, thereby pulling the insertion rod 14 out of the insertion hole 16 on the support plate 5, so as to facilitate the workers to adjust the position of the cover plate 3 and the filter screen 6.
