The drawing explanation:
Fig. 1 is the structural representation of Magic water energy mill.
Below in conjunction with accompanying drawing the utility model embodiment is described further:
Fig. 1 is the structural representation of Magic water energy mill.Magic water energy mill is made up of blade 1, bearing 2, rotary disk 3, bearing 4, tank 5, the blade 1 of the waterwheel rotary disk straight sheet that is rectangle is screwed cylindrical at rotary disk 2, the material transparent organic glass that disk 2 usefulness quality are light is made, and the center of disk 2 is equipped with steel hollow bearing 3 that make, that greasy property is good.
Blade 1, bearing 2, rotary disk 3 link together and are fixed on the bearing 4 of steel making, and the waterwheel formation one that the base of bearing 4 is the rectangle bloom and is connected self keeps balance to be placed on the base of tank 5.
The blade 1 that the bidirectional memory alloy is made, can be under the condition of temperature control T crooked and stretch by predetermined shape, after entering tank 5 and determining in the water of temperature, bend, produce striking effect, drive disk 2 rotations.In the process of making Magic water energy mill, to note:
1. need to select meticulously the material and the crooked shape of blade, subject matter is the temperature of selection bending blade and stretching, extension, the speed of generation deformation etc., and these problems need be determined through a large amount of experiments repeatedly.
2. the selection of rotary disk material and bearing mainly is that the disc material quality is wanted gently, but firm again, durable, attractive in appearance, is easy to processing.Bearing considers to use pneumatic bearing.
3. the selection of water temperature and control are by temperature control T control, and control water temperature is bending blade after arriving certain degree of depth.
Magic water energy mill also can be used as general science popularization showpiece, is placed in other exhibition section to show, its overall dimensions also can be done suitably to adjust according to the integrated planning of different exhibition sections.Magic water energy mill can be placed on the middle Room of science and technology center lobby, over against the grand entrance place, and whole high about 3.5 meters of waterwheel, about 3 meters * 4 meters of floor space (area of isolation that comprises 1 meter on periphery), it stands tall, and is noticeable.
The area of supposing blade is that (L * R), produce crooked angular velocity is W to S, and the radian that bends is for being the circular arc of radius with R, and the density of water is ρ.The thrust that produces when then bending blade is struck: fi pushes away (t1)=∫ RO w (t) L ρ dr wherein, i be blade ordinal number t1 be the i blade the time of striking and because disk drives the resistance that i sheet blade produces in water can be estimated as:
Wherein: have the time of in water, experiencing behind the i bending blade so V is the speed t2 that disk rotates, rub when fi pushes away (t1)-fi resistance (t2)-f sky-f 〉=0 wherein: f is empty when for air the resistance f of disk motion being rubbed frictional force into the disk rotary bearing, the sustainable rotation of disk.
