Abstract
The utility model discloses a blade rotating device in fluid. The spindle is provided with a large gear and connecting sleeves. A blade supporting arm frame is fixed on the corresponding cantilever between the two connecting sleeves. Each blade supporting arm frame is provided with a blade shaft base and a blade rotating shaft capable of moving along the blade supporting arm frame. Each blade rotating shaft is provided with a blade. Each blade supporting arm frame is provided with a regulating rotating shaft. The regulating rotating shaft is fixedly provided with a reel. A pull rope is positioned between the reel and the blade shaft base. The lower end of each regulating rotating shaft is provided with a small gear engaged with the large gear on the spindle. The utility model has the advantages of adjustable moment and high power, which can be used to drive other working machines.
Description
The utility model belongs to wind motor.
Utilize fluid to produce power, it is a kind of very ancient method, as various windmills, all kinds of current are changed trains or buses etc., but no matter which kind of windmill or current are changed trains or buses, all be to utilize fluid to impact blade, make blade drive main shaft and rotate, and all these class machinery windmills or current are changed trains or buses under rate of flow of fluid alters a great deal situation, braking torque changes also very greatly, corresponding revolution changes greatly, and the working machine that is driven can not adapt to.A kind of propeller formula windmill is arranged at present, is to stretch out several blades on a main shaft, and this windmill is subjected to structural limitations, and power is little, particularly when rate of flow of fluid hour, can not work.The moment that is produced can not change.
The purpose of this utility model is the shortcoming that overcomes prior art, provide a kind of can be under rate of flow of fluid alters a great deal situation, by the adjusting vane position, corresponding adjusting arm of force size, stabilizing moment is stablized revolution, and can produce in the fluid of big braking torque the blade revolving type and change trains or buses.
For achieving the above object, the utility model is installed a main shaft on gearbox, by Bearing Installation a gearwheel is arranged on main shaft; Connecting sleeve also is installed on main shaft, blade support arm frame is installed on corresponding cantilever between two connecting sleeves, up and down all be equipped with and frame shift the blade axle bed moving along the blade support arm in both sides, on the blade axle bed, blade rotor is installed at each blade support arm frame; A blade is all arranged on every blade rotor; On each blade support arm frame, also have one to regulate rotating shaft, fix wired the wheel regulating in the rotating shaft, online take turns and the blade axle bed between be wound with a rope; Every regulate the rotating shaft lower end all be equipped with main shaft on the small gear of gearwheel engagement.
Advantage of the present utility model is: compact structure, and the moment can regulate, under the rate of flow of fluid situation of change, revolution is stable, and braking torque is big.

Describe in detail below in conjunction with accompanying drawing.
The utility model has a gearbox 1, a hollow spindle 2 is installed on gearbox, on main shaft 2, a gearwheel 7 is arranged by Bearing Installation, on gearwheel 7, handle with sleeve is installed, on main shaft 2, also be fixed with at least one plane multi-arm connecting sleeve 8, one four arm connecting sleeves 9A and a multi-arm connecting sleeve 9; Cantilever is all arranged on each connecting sleeve, blade support arm frame 5 is installed on cantilever relative between two connecting sleeves.As Fig. 1, Fig. 2 and Fig. 6, shown in Figure 7, each blade support arm frame respectively have up and down a blade axle bed 15 and 15 ', a stationary axle 16 is installed in the left side of blade axle bed; Blade rotor 17 is installed on the right side, and blade 4 is installed on the blade rotor 17 and can rotates around blade rotor, and said blade axle bed can drive blade rotor and blade is frameed shift moving along support arm.An adjusting axle 10 that is used for the adjusting vane position also all is installed on each blade support arm frame, for easy for installation, adjusting axle in separated, link together by star coupling then.In the lower end of every adjusting axle, all be fixed with one with main shaft on gearwheel 7 pinion in mesh 3, on every adjusting axle, also be fixed with four lines wheel 11, on each blade support arm frame, corresponding line pulley is installed also.Two lines wheel on adjusting axle and below two lines wheels on all be wound with a stay cord 6 and 6 ', and every stay cord all is connected with the blade axle bed, the rope winding direction of taking turns at corresponding two lines on the adjusting axle is opposite.As shown in Figure 1, for easy for installation, on cantilever topmost, be fixed with hanger, in the main shaft upper end pulley is installed, in the main shaft lower end pulley 12 is installed also, on pulley spindle, also is fixed with a ratchet 13, a ratchet 14 with ratchet engaged also is housed on pulley bracket; Two stay cord one ends are fastened on hanger, after the other end passes hollow spindle, reach the outside and are suspended on the pulley 12.
During use, with stone bolt this device is fixed on the ground, the support arm frame can be assembled into multilayer as required, so as to increasing the blade number, if use in water, then needs the main shaft upper end is also fixed by a bearing support.Move small gear 3 rotations that the handle on the gearwheel is engaged with gearwheel 7 drives then, thereby adjusting axle 10 is rotated, adjusting axle 10 drives the position of blade axle bed adjusting vane on support arm by stay cord 6, fluid (wind or current) impacts blade and produces power, drive support arm and main shaft and rotate the generation braking torque, because braking torque can be regulated by the position of adjusting vane on the support arm frame, so under the rate of flow of fluid change conditions, can stablize revolution, the output frequency of the working machine that makes it to drive is stable.Forward to when producing resisting moment one side when blade in addition, parallel because blade can rotate around blade rotor with direction of flow, thus can reduce resisting moment to greatest extent, thus drive other device as generator etc.
Claims (1)
