Abstract

The invention provides an energy collector being able to collect the kinetic energy of wind, water flow and other sorts of fluid. When a blade of a collecting wheel confronts with the fluid, the blade can deflect around an auxiliary axle under the action of fluid and the flow confronting area can be reduced because a blocking device on a frame can only realize one-way blocking. A pressure difference is produced by a flow confronting blade and a blade going with the fluid and then a kinetic energy collecting wheel can rotate around the main axle. At times of gale or surge, the rotate speed of the kinetic energy collecting wheel can be too high and a slide block can move eccentrically and draw a traction rope under the action of inertia; a spring shrinks under pressure; the blocking device is drawn away from the original position and fails to block the blade. The blades can rotate freely and deflect around the auxiliary axle under the push of fluid, so as to reduce the flow confronting area. The pressure difference between the flow confront blade and the blade going with the flow is reduced and the rotate speed of the kinetic energy collecting wheel is lowered down to prevent the damages to equipment.

Description

Fluid kinetic energy collecting wheel
Technical field the present invention is a kind of energy harvester of collecting fluid dynamic energies such as wind and current.
The present windmill of background technique mostly is horizontal axis wind turbine greatly, and these windmills take up room greatly, and place and the environment of installing had more requirement, in real work is used all inconvenience is arranged.Wind speed is too fast to cause damage to windmill easily.Order of the present invention ground will provide a kind of exactly and can work under multiple environment, vertical shaft simple in structure, the fluid kinetic energy collecting wheel of controlled speed.
When summary of the invention was in the fluid flow environment such as wind or sea wave as well as tide when kinetic energy collecting wheel, the kinetic energy that fluid cross is flowed transformed into the kinetic energy that self rotates, and then was generating or ready as other energy output.
When the kinetic energy collecting wheel face of blade is met to fluid, be subjected to the effect of fluid, the flow direction motion of following current body, and the one-way check device that promotes on countershaft and the framework makes the collection wheel rotate around main shaft.When blade forward during fluid, because of the retention device on the framework is an one-way check, do not play barrier effect this moment, and blade can only be around countershaft deflection.At this moment forward the long-pending fluoran stream surface of meeting much smaller than the front to the fluid blade of the fluoran stream surface of fluid blade amasss.Produce pressure difference between blade and the blade, fluid kinetic energy collecting wheel just gets up around main axis rotation.
As blast or billow, equipment is destroyed easily when rate of flow of fluid is too fast.We can not change physical environment, and are long-pending but we can adjust the blade fluoran stream surface.When collecting the whole rotating speed of wheel just often, retention device can transmit the kinetic energy that blade is collected.When the whole rotating speed of collection wheel was too fast, slide block can be because of the inertial centrifugal pulling traction rope.The spring pressurized shortens.Self-locking on the retention device is bumped pearl and is broken away from limited impression.Retention device is pulled away from original position.At this moment blade can freely rotate, and is subjected to hydrodynamic pressure around countershaft deflection, and fluoran stream surface is long-pending to diminish.The long-pending ratio of the fluoran stream surface of main shaft both sides blade is dwindled, and produces pressure difference between blade and the blade and dwindles, and causes collecting wheel speed and slows down.Avoided equipment to be destroyed.

This fluid kinetic energy collecting wheel of embodiment comprises a main shaft (1), and the main shaft bottom is battery limits (10), as generator or the like.Also comprise several blades (2), each blade all is fixed on separately the framework (4) by a countershaft (3).Retention device (5) is housed on the framework.Slide rail is equipped with in retention device and framework joint, and pearl (9) is bumped in self-locking.Spring (8) is housed on the retention device, and spring is connecting main shaft.Slide block (6) is housed on the framework.Tow rope is housed on the slide block, and tow rope hauls by pulley (7) and stops.

Claims (3)

1. the present invention is a kind of energy harvester of collecting fluid dynamic energies such as wind and current, and it is characterized in that: this fluid kinetic energy collecting wheel comprises a main shaft (1), and the main shaft bottom is battery limits (10), as generator or the like.Also comprise several blades (2), each blade all is fixed on separately the framework (4) by a countershaft (3).Retention device (5) is housed on the framework.Slide rail is equipped with in retention device and framework joint, and pearl (9) is bumped in self-locking.Spring (8) is housed on the retention device, and spring is connecting main shaft.Slide block (6) is housed on the framework.Tow rope is housed on the slide block, and tow rope is connecting retention device by pulley (7).
2. fluid kinetic energy collecting wheel according to claim 1 is characterized in that main shaft (1) and countershaft (3) all are the vertical shaft of vertical ground.To adapt to the environment that requirement for height can not be too high.When the fluid smooth flow, different because of blade with the inflow angle degree of blade, make to produce pressure difference between the blade, promote whole wheel rotation, fluid dynamic energy is converted to the energy of collecting wheel.
3. fluid kinetic energy collecting wheel according to claim 1 is characterized in that this collection wheel is equipped with the control rate device.To avoid because flow rate of fluid is too fast, perhaps flow rate of fluid, flow to indefinite, thereby the device that causes damages.
