The above and other objects and advantages of the present invention will become more apparent from the detailed description of the embodiments. Of course, the present invention differs in some of the components, or the arrangement of the components, but the selected embodiments are described in this specification and their construction is shown in the drawings. - [Embodiment] Please refer to Fig. 1 to Fig. 4, which shows the structure of an embodiment of the present invention, which is for illustrative purposes only, and is limited by the specific structure. (4) In the first and second figures, the description of the embodiment of the wind power generation device of the Japanese-made water-construction water structure includes: a generator set 1, one side of the generator body 1 Cover 2 1 cover body 中央 2 center away from the body 丄i convexly provided with a set of seat transmission sleeves 1 3 centrally provided - shaft hole 14, the shaft hole 1 4 generator 凸 protruding - "W 5 wear And the outer peripheral ring is provided with at least one first groove for concentrating and guiding the liquid. In the embodiment, the first groove 131 is attached to the sleeve. The first-and second-cut faces 132 and 133 are formed on one side of the first-cut face i 32 with a predetermined angle of inclination on the side of the first-cut face i 32. The first groove 131. 7, the blade group 2' is composed of - the shaft seat 2 1 is provided with a plurality of connecting portions 2, the money connecting portion 2 7 is provided with blades (not shown), and the central side of the shaft is axially convex The first and second shaft portions 2 2, 201126063 2 3 'the second shaft portion 2 2, 2 3 are axially provided with a central sleeve hole 24 for the shaft 1 of the generator set 2 5, the shaft portion 2 3 is internally provided with a bore 2 5 , the inner diameter of the bore 25 is slightly larger than the outer diameter of the sleeve 13 for interfacing with the sleeve 3 The second shaft portion 23 has a suitable gap between the outer circumference of the sleeve 1 3 and the cover body 2, and the outer circumference of the second shaft portion 23 is provided with at least one second for concentrating the liquid. In the embodiment, the second groove 213 is disposed at a predetermined angle of inclination of the second shaft portion 23 in a radial direction to form a first cut surface 2 3 2 . A second cutting surface 2 3 3 having a predetermined inclination angle is disposed on one side of the first cutting surface 2 3 2 , and the first and second cutting surfaces 232 and 233 3 together constitute the second groove 231 . Further, the cover body 1 2 is sleeved with the seat 13 and the second portion of the shaft seat 2 1 and the second shaft portion 23 of the d-axis seat 2 1 and the outer periphery of the sleeve 1 3 and the cover 1 2 The gap, and each of the first and second trenches 丄3丄, 231, can form a non-contact seal design of a curved labyrinth gap 26. An air guiding seat 3 is disposed on a side of the first shaft portion 2 2 of the shaft seat 21, and a central shaft portion 31 of the air guiding seat 3 is connected to the rotating shaft 15 In this embodiment, the shaft portion 31 of the air guiding seat 3 is interlocked with the rotating shaft 15 by a fixing member 32. When the invention is used, as shown in FIG. 3, when the blade of the blade group 2 is windy, it can drive the rotation of the shaft base 21 to rotate the rotating shaft 15 of the generator set 1, thereby causing the kinetic energy of the genset 1 to be mechanically kinetic. Converted into electric energy output, and when the blade group 2 is in operation, due to the labyrinth gap between the cover body 1 2 and the shaft base 2, the liquid or dust in the air is not easy to enter the 201126063 air gap 2 6 ' If the liquid or falling dust in the air enters the inside of the body 1 i of the genset 1 under wind entrainment, an air flow is generated when the rotating shaft i 5 and the shaft seat 2 1 rotate, and the airflow passes through the labyrinth gap 26 to cause a pressure difference. The liquid will concentrate on the first and second grooves 1 3 1 , 2 3 1, and the centrifugal force generated when the first and second grooves i 3 1 , 2 3 1 rotate, and the liquid can be cleaved. The first groove 丄3丄 can guide the liquid to escape the second shaft portion 23 along the bristles 26, and the leakage of the liquid or the falling dust passing through the labyrinth gap 26 is smaller, thereby achieving waterproofing. Dustproof effect. Moreover, when liquid or falling dust flows in the labyrinth gap 26, friction between the liquid and the labyrinth wall is caused by the liquid viscosity, and the liquid forms a frictional effect along the gap of the flow channel, so that the flow velocity is slowed down and the leakage amount is reduced. The longer the flow path formed by the 6th, the more obvious the frictional effect is, which can enhance the waterproof and dustproof effect. Of course, there are still many examples of the present invention with only minor changes in detail. Please refer to FIG. 4, which is a second embodiment of the present invention, wherein the cover body 12 and the shaft base 21 can be provided with the first and second sets of joints, 6 and 2 3 4 . The first set of joints 6 is provided with a ship-shaped convex portion or a ring groove at a predetermined position of the cover body 2, and the second set of joint portions 2 3 4 is corresponding to the first set of joint portions. And the second shaft portion 23 of the axle seat 2 is provided with a ring groove or a convex portion having a concave preset shape, which is mutually configurable with the first group joint portion, and each of the convex portion and the ring groove There is a preset gap: to form a labyrinth gap 2 6 1 'to increase the length of the runner of the labyrinth gap 26, to slow down the flow rate, and to reduce (4) or the amount of leakage of dust through the labyrinth gap 26, In turn, it improves the waterproof and dustproof effect. In summary, there is a gap structure between the generator set and the blade set 2 of the present invention, which is a non-flip seal material, and the cover body of the generator set 201126063 1 and the shaft base 2 of the blade set 2 The first and second grooves i 3 and the labyrinth _ 2 6 ' can be used to concentrate and guide the liquid, and the liquid or dust can be opened by the rotation, and the labyrinth The difference between the force and the friction effect produced by the gap 2 6 , avoiding the liquid and the falling of the deep human 'inspection and touch the fruit, · the; the shaft 1 of the motor unit 1 and the shaft seat 2 of the blade group 2 There is a gap, so it can be allowed to have thermal expansion, suitable for high temperature, high frequency and high speed. 'The overall structure of the invention is simple and durable, no adjustment is needed, assembly and maintenance are easy, and there is no contact friction, so the generator set is in working condition. Under the circumstance, the friction resistance is not reduced or the efficiency is lost, so as to increase the life of the money. The present invention is not to be construed as being limited to the details of the present invention.
