The ventilated heat sink for energy conservation of buildings according to claim 1, wherein: the upper surfaces of the blades (4) are provided with water drainage grooves (4-1), and the water drainage grooves (4-1) on the adjacent blades (4) at the head and the tail are arranged in a vertically through manner.
8. The ventilated heat sink for energy conservation of buildings according to claim 1, wherein: the bottom surface of the blade (4) is fixed with a photovoltaic plate in the solar photovoltaic module (24), the electric control ends in the solar photovoltaic module (24) are all arranged in a groove body at the bottom in the side wall of the fixing frame (2), and the solar photovoltaic module (24) is electrically connected with the storage battery (22).
9. The ventilated heat sink for energy conservation of buildings according to claim 1, wherein: the working principle is as follows:
when the maximum ventilation is needed in sunny days, the motor (23) is used for controlling the gear (5) at the lowest side to rotate, the gear (5) at the lowest side drives the gears (5) above to rotate simultaneously by the aid of the chain (7), further drives the rotating shaft (6) and the blades (4) connected to the rotating shaft (6) to rotate to be in a horizontal state, the ventilation volume reaches the maximum, meanwhile, the forward and reverse fans (3) are started to alternately rotate forwards and reversely, and indoor and outdoor air is circulated and replaced;
in cloudy days, under the condition that the outdoor air quality is not very high, the motor (23) is utilized to control the gear (5) at the lowest side to rotate, the gear (5) at the lowest side drives the gears (5) at the upper side to rotate simultaneously by the aid of the chain (7), so that the rotating shaft (6) and the blades (4) connected to the rotating shaft (6) are driven to rotate in an inclined state, a certain gap is formed between every two adjacent blades (4), the ventilation quantity is reduced at the moment, the forward and reverse fans (3) are started to rotate forwardly at the same time, indoor air is transmitted to the outdoor, and outdoor air enters the indoor room in small quantity under the action of natural wind;
in light rain weather, the pull rod (12) is manually pushed to the outside of the room, the seal end cover (8) is reversely opened to the outside by the pull rod (12), and then the screw rod (19) is screwed into a threaded hole formed in the inner side wall of the bottom of the frame body of the forward and reverse fan (3) to fix the pull rod (12); then, a motor (23) is used for controlling the gear (5) at the lowest side to rotate, the gear (5) at the lowest side drives a plurality of gears (5) above to rotate simultaneously by a chain (7), and further drives a rotating shaft (6) and blades (4) connected to the rotating shaft (6) to rotate to be in an inclined state, the inclined state is that the upper surfaces of the blades (4) face to the outside, a certain gap is formed between every two adjacent blades (4), at the moment, the ventilation quantity is reduced, a forward fan (3) and a reverse fan (3) do not work, indoor air and outdoor air are exchanged under the action of natural wind, meanwhile, rainwater is beaten on the blades (4) and falls into a rainwater collecting tank (9) from the blades (4), and flows into an indoor water tank (11) through a water drain pipe (10), the rainwater is effectively collected, and is filtered and reused at the later stage;
when heavy rain weather, screw rod (19) are twisted out from the screw hole of seting up in positive and negative fan (3) framework bottom inside wall, pull rod (12) return indoorly, end cover (8) are closed on rainwater collecting vat (9) to the rotatory lid in the right side under the effect of extension spring (16) this moment, then it is rotatory to utilize motor (23) to control gear (5) of downside most, gear (5) of downside utilize chain (7) to drive a plurality of gears (5) of top rotatory simultaneously, and then it is the tilt state to drive pivot (6) and connect blade (4) rotation on pivot (6), contradict each other between adjacent blade (4) and set up, and positive and negative fan (3) are out of work, indoor outside air does not take place the circulation this moment, avoided outside rainwater to squeeze into indoorly.
