Paddle, including diversion pipe 1 and with the propeller 2 of at least one paddle 21, paddle 21 includes the flap 202 of front end region, spiral shell
Rotation paddle 2 is arranged in the following manner in diversion pipe 1: making between 1 inner wall 6 of flap 202 and diversion pipe of 21 front end region of paddle
The turbulent slot 106 of the circumferencial direction along diversion pipe 1 is formed, 1 water inlet end of diversion pipe is equipped with protective cover 7, in 7 one end face of protective cover
It is evenly equipped with 73 ring cloth of blend stop connection, 74 surface of annulus, is equipped in annulus 74 and turns ball 75, is equipped with to be distributed in protective cover 7 and turns on ball 75
Blade 76, turning ball 75 can rotate in annulus 74.By being arranged propeller in diversion pipe, make paddle front end region
The turbulent slot that the circumferencial direction along diversion pipe is formed between flap and water conservancy diversion inside pipe wall, can be rolled over by paddle front end region
Marginal flow in turbulent slot can be introduced in propeller area, reduce and form turbulent flow in propeller shrouding by the rotation of the wing,
Reduce in the unit time through the water in gap between propeller and diversion pipe, improves propeller overall performance, diversion pipe
The protective cover of water inlet end setting, is evenly equipped with blend stop in one end face of protective cover, the impurity in some water can be blocked in it is outer,
It prevents some objects from entering in propeller, damages screw blade, meanwhile, setting is distributed in the blade turned on ball in protective cover,
The ball that turns can rotate in annulus, and blade is made to rotate under the flowing of water, to enter protective cover in some water plants into
Row cutting, prevents its winding screw blade, improves device and uses safety coefficient, and the present apparatus is reasonable in design, and energy loss is small,
It is small by sea beat when working in water, long service life, and the operation is stable in water, high reliablity, work efficiency is high.
Paddle 21 further includes the bent leaf 201 for connecting rear end region by hinge 205 with the flap 202 of front end region,
Bent 201 curvature of leaf proportion is at non-constant, and 202 back of flap is connect with 204 one end of telescopic putter, and 204 other end of telescopic putter is consolidated
Surely it is connected to 203 surface of pulp hub, the flap of setting paddle front end region is connected by hinge the Qu Ye in rear end region, faces
Different status of the water area, it is flexible by telescopic putter, flap flip angle is adjusted, thus under different water environments, propeller
It can work normally, increase the practicability of device.
Turbulent slot 106 includes lower convex edge 104 and upper convex edge 105, and the projecting height of lower convex edge 104 is greater than upper convex edge 105
Projecting height, upper 105 outer surface of convex edge be equipped with the inclined-plane 107 of setting being inclined outwardly, and is evenly equipped with and is obliquely installed on inclined-plane 107
Diversion rod 108, inclined direction is identical as 21 direction of rotation of paddle, and multiple balls 109 are mounted on diversion rod 108.Setting turbulent flow
Slot includes lower convex edge and upper convex edge, and the projecting height of lower convex edge is greater than the projecting height of upper convex edge, can reduce vacuum side of blade end
The pressure in portion, upper convex edge outer surface setting are inclined outwardly the inclined-plane of setting, water flow are enable to converge to middle part of blade along inclined-plane,
The water flow in turbulent slot is reduced, meanwhile, the diversion rod being obliquely installed, inclined direction and paddle direction of rotation phase are evenly equipped on inclined-plane
Together, it is mounted with multiple balls on diversion rod, increases the frictional force of fluid viscosity generation, adds fluid along the movement of direction of rotation
Speed keeps the velocity profile of this direction flow velocity more plentiful, therefore its boundary layer is thinner, and the water in boundary layer enters mainstream and along rotation
Turn direction and flows to lagging edge, and exactly the opposite on blade back, the flowing this reduces blade face to blade back, weaken blade surface
The radial migration in boundary layer acts on, and weakens tip whirlpool, and improve the spacious water efficiency of propeller.
