[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By providing an air-guiding component, when the hydraulic rod contracts, the wind enters the first cavity through the internal air groove and the air-guiding connecting pipe, and at the same time, the gas in the second cavity enters the fixed connecting pipe through the rotary joint. When the hydraulic rod extends, the gas in the first cavity enters the second cavity through the connecting short pipe, so that the wind on one side of the filter baffle can be transported to the cylindrical tube through the internal air groove. The rotor structure can transfer heat to the protruding long block, and the wind flowing in the internal air groove can take away the heat from the protruding long block, thereby realizing heat dissipation of the rotor structure, improving the flow rate of air in a dense environment, and thereby improving the heat dissipation rate of the generator rotor.

[0016] Through the cooperation of the air guide component and the air exhaust component, the gas in the second cavity enters the air guide elbow, and the heat dissipation fins can dissipate heat for the gas in the air guide elbow. The gas after heat dissipation in the air guide elbow enters the annular air cavity, and the gas is ejected from the air outlet tube. The gas can blow off the dust on the surface of the machine base ring cover. At the same time, the blowing of gas can also accelerate the air flow on the surface of the machine base ring cover and the heat dissipation guide plate, thereby accelerating the heat dissipation of the machine base ring cover and the heat dissipation guide plate.

[0017] By providing a rotor heat-conducting component, the fan blades rotate along with the installation long rod. Under the action of the fan blades, the air flow in the middle slot is accelerated, and part of the wind can enter the air guide slot. The middle slot is connected to the air guide slot through a connecting circular hole, thereby realizing ventilation and heat dissipation inside the rotor structure.

[0018] By providing a dispersion component and an exhaust component, the cylindrical tube rotates along with the installation long rod, driving the inner gear ring to rotate, the inner gear ring engages with the gear, the inner gear ring drives the gear to rotate, and the gear drives the blowing blades to rotate through the connecting column. The blowing blades accelerate the air flow and prevent the hot air coming out of the air outlet filter plate from gathering around the generator and affecting the heat dissipation of the generator. At the same time, the rotation of the blowing blades can also accelerate the heat dissipation of the heat dissipation fins, thereby increasing the cooling rate of the gas in the air guide elbow, thereby improving the heat dissipation efficiency of the generator.
