Ventilation and heat dissipation apparatus of wind-assisted rotor

A ventilation and heat dissipation apparatus of a wind-assisted rotor, comprising:

• a cylinder;
• a top cover disposed at a top of the cylinder and covering the top of the cylinder, wherein the top cover is provided with a manhole communicating with an inner cavity of the cylinder;
• a rain shielding plate disposed above the manhole and covering the manhole, wherein the rain shielding plate and the top cover are spaced apart to form a heat dissipation gap that communicates with an external atmosphere;
• and
• a reinforcement assembly, wherein the reinforcement assembly comprises:
• a lining plate disposed between the rain shielding plate and the top cover;
• and
• reinforcement ribs, wherein a first end of each of the reinforcement ribs is fixedly connected to the lower surface of the rain shielding plate, and a second end of the each of the reinforcement ribs is fixedly connected to an upper surface of the lining plate;
• and
• wherein the lining plate and the rain shielding plate are spaced apart to form the heat dissipation gap;
• and
• wherein the lining plate comprises a first lining plate and a second lining plate which are connected at a second preset angle, wherein
• the first lining plate is an annular plate and is disposed on an inner side of the second lining plate, and
• the second lining plate is an annular slanted plate, and an end of the second lining plate facing away from the first lining plate is slanted downward towards the top cover.
