Preferably, the fixing ring 201 is connected with the mounting frame 101 through a first bearing 500, the rotating disc 303 is connected with the rotating member 102 through a second bearing 600, and the mounting frame 101 is provided with a plurality of mounting holes 101b at its periphery for mounting on a wall surface.
It should be noted that, in the present embodiment, six vanes 104 are provided, the angular arc of the sector of the vane 104 is 60 °, and the rotating rod 103 is located on the central axis of the vane 104.
The principle and implementation of this embodiment are: the invention is mainly divided into two states when in work:
when the high-voltage distribution room of the transformer substation does not need ventilation: at the moment, the motor M does not work, and if the ventilating window in the prior art is used, because the ventilating window does not have an adjusting function, dust is easy to accumulate at the window and is difficult to clean, particularly, in strong wind in spring and rainy days in summer, dust, fine sundries, insects, rainwater and the like are easy to enter the power distribution room from the ventilating opening, so that the power distribution room is dirty; the blade 104 can be adjusted to be a circular plane, the mounting frame 101 is sealed, when the operation is performed, only the adjusting piece 401 is pressed to enable the limiting boss 401c to be separated from the limiting groove 402b, then the rotating disc 303 can be rotated, when the rotating disc 303 rotates, the ball 302 moves in the cylindrical groove 303a and deviates from the rotating disc 303, then the ball 302 drives the swing rod 301 to rotate by taking the rotating rod 103 as a circle center, then the rotating rod 103 rotates, the blade 104 is adjusted to be positioned on the same plane, the adjusting piece 401 is released, the adjusting piece 401 resets under the action of elastic force of the elastic piece 404, the limiting boss 401c is embedded in the limiting groove 402b to limit the rotating disc 303 and parts linked with the rotating disc 303 to move, and therefore the ventilation assembly 100 cannot ventilate and cannot have dust, fine sundries, insects, rainwater and the like which easily enter the power distribution chamber from a ventilation opening;
secondly, when the high-voltage distribution room of the transformer substation needs ventilation: at this moment, like the above operation, adjust blade 104 to certain angle, and adjust the size of air volume according to the on-the-spot condition, mainly adjust the contained angle between the plane at blade 104 and dwang 103 place, the air volume is big when the contained angle is big more, fixes blade 104 after confirming the contained angle, then opens motor M and can ventilate, can also discharge dust and tiny debris, insect, rainwater etc. of window department.
