For example, the rotating impeller structure is used specifically as follows: when need generate electricity or make work, need the rivers promote rotatory impeller structure is rotatory, rivers in the river course promote a plurality of flabellums drive the wheel body is rotatory, because the axis of rotation axis is relative the liquid flow direction slope setting in river course makes consequently the flabellum can not openly be met rivers, makes things convenient for debris to follow then the side flow direction of flabellum is less than, thereby makes rotatory impeller structure is difficult for blockking up. In addition, because the wheel body is adjustable in height relative to the river channel, the plurality of fan blades can be driven to be too high in height, so that impurities at the bottom can flow out, and the rotary impeller is further enabled to be not easy to block. For example, the height of the wheel body may be adjusted by detachably supporting the rotary shaft on the mounting frame so that the height of the rotary shaft may be raised after the rotary shaft is detached, or by movably supporting the rotary shaft on the mounting frame so that the height of the rotary shaft may be raised by lifting the rotary shaft, or by providing a lifting cylinder to raise the rotary shaft so that the height of the wheel body may be raised.

For example, in order to facilitate the height adjustment of the wheel body, the mounting frame includes two oppositely disposed supporting seats, and the two supporting seats are respectively disposed on two opposite sides of the river channel. The two supporting seats are telescopic supporting seats, arc-shaped grooves are concavely formed in the tops of the two supporting seats, and the two opposite ends of the rotating shaft are rotatably arranged in the arc-shaped grooves of the two supporting seats respectively. The wheel body is discoid, a plurality of flabellums all outwards extend along the radial direction of wheel body. The width of flabellum is along keeping away from the direction of wheel body increases gradually, the tip of flabellum sets up wear-resisting cover. The end edges of the fan blades form included angles relative to the horizontal plane, and the included angles are 15-30 degrees. The end part of the wheel body is convexly provided with a driving cam 23, and the driving cam is made of steel. Through inciting somebody to action two supporting seats of mounting bracket set up to flexible supporting seat to can improve the height of rotation axis, and then adjust the height of wheel body both can get rid of impurity in order to prevent blockking up, also can adapt to the surface of water height in dry season and flood period.

For example, the present invention also provides a pumping mechanism. Pumping mechanism includes drinking-water pipe 24, piston structure 25 and as above rotatory impeller structure, the drinking-water pipe is held and is gone out the water end including absorbing water of relative setting, the end that absorbs water is put into the river course, be provided with valve structure in the middle part of drinking-water pipe, the middle part of drinking-water pipe is passed through piston structure with the drive cam of wheel body is connected, drive cam promotes piston structure reciprocating motion, and utilizes valve structure realizes the operation of drawing water. For example, the valve structure comprises two valves, wherein the two valves are an upper one-way valve and a lower one-way valve which are oppositely arranged, when the piston is pulled, the upper one-way valve is closed, and the lower one-way valve is opened, so that water flows into the space between the upper one-way valve and the lower one-way valve from the lower part. When the piston is pushed, the lower one-way valve is closed, and the upper one-way valve is opened, so that water between the upper one-way valve and the lower one-way valve flows out of the upper one-way valve. Through setting up the drinking-water pipe with piston structure to make the drive cam on the wheel body promote piston structure reciprocating motion, and then rely on valve structure realizes the operation of drawing water of drinking-water pipe is power consumptive, not oil consumption, the non-staining environment again.

For example, in order to achieve the reciprocating motion of the piston structure, the piston structure includes a piston cylinder 251, a piston (not shown), a piston rod 252 and a return spring, one end of the piston cylinder communicates with the pumping pipe, the piston is slidably disposed in the piston cylinder, the piston rod is convexly disposed on the piston, an abutting portion 253 is formed at an end of the piston rod, the abutting portion abuts against the driving cam, the return spring is sleeved on the piston rod, and opposite ends of the return spring respectively abut against the piston cylinder and the abutting portion.

By providing an abutting portion on the piston rod so as to abut against the drive cam, the rotational motion of the rotary impeller structure is converted into the reciprocating motion of the piston. And the guide rod on the piston cylinder can support the guide piece on the piston rod, so that the piston rod is prevented from shaking up and down.

For example, it is particularly important to refer to fig. 2 that, in order to increase the working frequency of the driving cam, two driving tips 231 are disposed on the driving cam, the two driving tips are disposed opposite to each other, and by disposing the two driving tips, the driving cam can push the abutting portion 253 of the piston rod twice in the process of one rotation, so as to increase the pushing frequency of the driving cam, and improve the working efficiency of the driving cam. For example, in order to avoid hard contact of the driving tip portion with the abutting portion of the piston rod, an elastic layer is formed on the driving tip portion, a metal sliding layer is arranged on the surface of the elastic layer, an arc-shaped pushing surface is arranged on the metal sliding layer, and the arc-shaped pushing surface is in abutting contact with the abutting portion of the piston rod. The surface of the metal sliding layer is provided with the arc-shaped pushing surface, so that the contact friction force between the driving cam and the abutting part is reduced. And through setting up the elastic layer, then can make drive point portion can produce slight deformation, and then avoid the arc push away the face with the rigid contact of butt portion improves the shock-absorbing capacity, avoids the jamming that rigid contact brought. For example, drive point portion is kept away from during reset spring 26, in order to improve reset spring with drive cam's contact dynamics, so that butt portion in close contact with drive point portion, still be provided with protruding pulling rod 232 that is equipped with on the drive cam, the protruding locating of pulling rod is in on drive cam's the terminal surface and be close to one of them drive point portion, be provided with on the pulling rod and draw and hold strip 233, the fixed cover of one end of drawing holding the strip is located on the pulling rod, the other end fixed connection of drawing holding the strip in reset spring's middle part position.

When the driving tip part pushes against the abutting part, the pulling and holding strip can release the reset spring so as to reduce the pushing and supporting force of the reset spring, and therefore the piston rod is conveniently pushed to drive the piston to do work.

For example, in order to facilitate pulling and contraction of the pulling strip, the pulling strip is an elastic pulling strip, a sleeve ring 234 is formed at the end of the pulling strip, a steel ring is arranged on the inner side of the sleeve ring, the steel ring is rotationally sleeved on the pulling rod, in order to avoid winding of the pulling strip, a pulling hole is formed in the edge of the abutting portion, the middle of the pulling strip is arranged in the pulling hole in a penetrating manner, so that the pulling strip is protected and held by the pulling hole, winding of the pulling strip is avoided, and the pulling force applied to the return spring by the pulling strip can enable the return spring to contract towards the abutting portion without generating a deflected component force. For example, in order to ensure the positive pulling force of the piston rod, the guide rod is provided with a sliding groove, the end of the guide 28 on the piston rod is provided with a sliding ball, the sliding ball is slidingly clamped in the sliding groove, the sliding ball cannot be separated from the sliding groove but only can slide in the sliding groove, so that the piston rod can only transversely reciprocate without generating deflection motion through the matching of the guide and the guide rod, and can be better abutted against the drive cam.
