Novel fan blade device

Technical Field

The utility model relates to a wind power generation set field specifically indicates a novel fan blade device.

Background

Wind energy resources are beginning to receive widespread attention in the context of the global energy crisis and the increasingly severe environmental crisis. The rapid development of wind power generation provides wide market space and prospect for the manufacturing industry of wind power generation equipment. At present, the principle of wind power generation is that wind power is used to drive windmill blades to rotate, and then the rotating speed is increased through a speed increaser, so that a generator is promoted to generate electricity. According to current wind generator technology, a wind flow rate of about four meters per second can start generating electricity. The fan belongs to an axial flow fan, namely, the direction of wind flow is parallel to the direction of a rotating shaft, the structure characteristics determine that the fan has the following inevitable defects, the fan blades do circular motion around a hub, so the angular velocities of the fan blades at different positions are the same, but the linear velocities are different, the stress of each point is unbalanced, under a certain rotating speed, some places are positive forces, and some places are reverse forces, so that the efficiency is low, and meanwhile, the fan cannot be started easily due to the combined action of the positive forces and the reverse forces during starting, and has the defects of low efficiency, difficult starting and complex structure.

In view of the above technical problems, there are currently relative solutions:

FR2304790a1 relates to a planar fan with a double effect, the wind motor having two horizontal shafts at the top and bottom of the stand, respectively. Each shaft is provided with sprockets at both ends thereof, and an endless chain that passes around the sprockets. The chain is mounted on bearings by supporting a series of blades, always in optimum angle to be propelled by the suction pressure induced wind on their opposite surfaces. The bearing is preferably provided with a cut-out limiting the inclined fan blades.

FR2534636a1 relates to a turbine formed from a succession of parallel blades 1 holding panels and driven from either side by a sprocket-chain 2-3, a certain pin 4 carrying elements suitable for modifying and maintaining through which said circuit is travelled, according to the adjustment of said blades 1 of said section. The chains 2-3 are each tensioned over two wheels 30 and special teeth. Aiming said blades 1 to change their direction to said electric circuit where they move to said other side, these turbines can form very high wind-powered engines with a large surface area, kept aligned or staggered under metal gantry support, which will be automatically controlled either to pivot the effect of this change in the direction of the wind, or to adjust, according to said intensity of said wind, said power generator thereof and said tilting of said blades 1. These turbines, thus harnessing energy, will be the surge currents of the tides and oceans and rivers of the invention. Driving them by a motor will become the driving force of the fan, the marine track and the generator.

Above-mentioned two patents have overcome the inefficiency that traditional axial fan exists through sprocket and two-way flabellum mechanism, difficult start, the shortcoming of complicated structure, but two-way flabellum middle part articulates on the chain, through its slope of the longer arm control of one side length, therefore, if fluid kinetic energy is too big, then can have two-way flabellum to rely on the fluid flow direction completely and rotate, and then lead to there being sprocket chain one side flabellum atress pulling chain clockwise turning, and the condition of one side flabellum atress pulling chain anticlockwise turning in addition, finally lead to the unable normal start of device or the unable condition of rotating the power generation.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. Embodiments of the present invention include, but are not limited to, the following examples.

Example 1:

referring to fig. 1, a novel fan blade device includes rotating wheels 1 arranged in parallel, annular traction strips 2 are installed on the rotating wheels 1 arranged in parallel, the rotating wheels 1 and the annular traction strips 2 can be chain transmission mechanisms or belt transmission mechanisms, such as chain transmission mechanisms composed of chain wheels and chains, and belt transmission mechanisms composed of belt wheels and belts, generally, in order to have better transmission stability and avoid flexible pulling damage of fixing plates 41 installed on the annular traction strips 2 due to the fixed connection with the belt transmission, referring to fig. 1, the rotating wheels 1 and the annular traction strips 2 in this embodiment are chain transmission mechanisms composed of chain wheels and chains.

In order to absorb the kinetic energy of fluid (wind energy and water energy), the annular traction strip 2 is provided with a plurality of fan blade devices 4, each fan blade device 4 comprises a fan blade 42 for bearing the impact force of the fluid, the fan blades 42 on one side of the annular traction strip 2 and the fan blades 42 on the other side of the annular traction strip are distributed in the same direction, each fan blade device 4 further comprises a fixing plate 41 arranged on the annular traction strip 2, and the fan blades 42 are hinged to the fixing plate 41. Generally, the fan blade device and the fan blades are arranged in parallel, so as to ensure the stress directions of the fan blades are consistent, and the generating efficiency is improved to the maximum efficiency, wherein the fan blades 42 can be flat (polygonal) or arc (including upper arc and lower arc) and corrugated, the fan blades 42 can be rectangular, trapezoidal, parallelogram and the like, and are mainly used for bearing fluid impact force and further pulling the annular traction strip 2 to drive the rotating wheel 1 to rotate, and can be installed in an upward or downward inclined manner, the fan blades 42 are always distributed in a splayed manner when viewed from the side, and also can be inverted splayed, namely V-shaped, so that when fluid transversely passes through two rotating wheels 1 which are arranged in parallel, the fan blades 42 on one side of the annular traction strip 2 and the fan blades 42 on the other side can both move clockwise or anticlockwise to enable the rotating wheel 1 to rotate.

Because the fan blades 42 are hinged on the fixing plate 41, in order to ensure that the fan blades 42 on one side of the annular traction strip 2 and the fan blades 42 on the other side are in the same direction after rotating, so that the fan blades 42 rotate around the rotating wheel 1 to turn correspondingly and keep an inclined state in the up-and-down moving process of the chain, the rotating wheel 1 is coaxially provided with a chamfered column 3, and the fixing plate 41 is also provided with an auxiliary device 43 for assisting the fan blades 42 to turn and keep the inclined state.

Referring to fig. 2, the auxiliary device 43 of this embodiment includes an extending arm 4311 fixedly connected to the fan blade 42, the fixing plate 41 is further provided with a rotating arm 4313, the middle of the rotating arm 4313 is hinged to the fixing plate 41, one end of the rotating arm 4313 is connected to the extending arm 4311 through a connecting rod 4312, the other end of the rotating arm 4313 extends outward to contact the chamfer column 3, the connecting rod is hinged to the extending arm 4311 and the rotating arm 4313, and the connecting rod 4312 is connected to the middle of the rotating arm 4313 through an extension spring 4314. The extending arm 4311, the rotating arm 4313 and the pull rod form an N-shaped link 4312 system, the extension spring 4314 tensions the link 4312 and the rotating arm 4313 to ensure that a certain included angle is formed, so that the fan blade 42 can be kept in an inclined state under the action of the extension spring 4314, when the fan blade device 4 rotates over the chamfered column 3, the linear velocity is small because the extending rotating arm 4313 is close to the chamfered column 3, and the fan blade 42 on the fan blade device 4 is far away from the chamfered column 3, so the linear velocity is large, the chamfered column 3 abuts against the rotating arm 4313 to limit the rotation of the rotating arm 4313, after the fan blade 42 completely rotates over the chamfered column 3, the rotating arm 4313 bypasses the chamfered column 3, and it is worth noting that when the rotating arm 4313 is abutted by the chamfered column 3, the fan blade 42 is kept in an epicyclic motion state, so the rotating arm 4313 pulls the link 4312, the extending arm 4311 to drive the fan blade 42 to rotate, and finally after the fan blade 42 completely rotates over the chamfered column 3, the extending arm 4311, the rotating arm 4313 and the pull rod form an N-shaped connecting rod 4312 which is deformed by a mechanism, the fan blades 42 are kept in an inclined state under the action of the extension spring 4314, and finally the purpose that the fan blades 42 on one side of the annular traction strip 2 and the fan blades 42 on the other side are in the same direction after rotation and can absorb the kinetic energy of the fluid to the maximum extent is achieved.

Furthermore, a resisting plate 5 is arranged at one end of the rotating arm 4313, which is far away from the pull rod, and the contacting surface of the rotating arm 4313 and the chamfering column 3 can be further increased by the resisting plate 5, so that the fan blade 42 can be better assisted to overturn.

The working principle is as follows: when fluid flows through the space between the two parallel rotating wheels 1 from one side, downward pressure is formed on the left fan blade 42, upward lifting force is formed on the right fan blade 42, all the fan blades 42 generate forward force rotating anticlockwise under the action of reverse force on the two sides, the annular traction strip 2 drives the rotating wheels 1 to output power, and finally the rotating wheels are connected with the variable-speed motor through the driving shaft to drive the generator to generate power.

Example 2:

this embodiment is the same as the other parts of embodiment 1, and will not be described herein again, and only the auxiliary device 43 different from the embodiment will be described.

Referring to fig. 3, this embodiment has the same rotating wheel 1, annular towing bar 2, and chamfering column 3 mechanism as embodiment 1, and the fan blade device 4 has the same fixing plate 41 and fan blades 42, and the difference is only that the auxiliary device 43 for assisting the fan blades 42 to turn and maintain the inclined state is different.

Referring to fig. 4, the auxiliary device 43 of this embodiment includes a resisting rod 4323 fixedly connected to the fan blade 42, an angle formed by the connection of the fan blade 42 and the resisting rod 4323 is an obtuse angle, a torsion spring 4322 is installed on the fixing plate 41, one of two rotation arms of the torsion spring 4322 resists the fixing plate 41, and the other rotation arm resists one of the fan blade 42 or the resisting rod 4323. The obtuse angle formed by the fan blade 42 and the retaining bar 4323 has the following functions: as shown in fig. 3, the leaf 42 on the left side of the rotary wheel 1 presses one rotary arm 4313 of the torsion spring 4322, so that the leaf 42 on the left side of the rotary wheel 1 is kept in a downward inclined state toward the outside; and the abutting rod 4323 on the right side of the rotary wheel 1 presses the torsion spring 4322, so that the fan blades 42 on the right side of the rotary wheel 1 are maintained in a downward inclined state toward the outside. If the included angle formed by the fan blade 42 and the resisting rod 4323 is a right angle, after the fan blade 42 rotates through the rotating wheel 1, the resisting rod 4323 will resist against the torsion spring 4322, but the fan blade 42 will be in a vertical state, and fluid will not pass through the area between the rotating wheels 1 arranged in parallel, and at the same time, the annular traction strip 2 cannot be driven to drive the rotating wheels 1 to rotate; if the included angle formed by the fan blades 42 and the resisting rod 4323 is an acute angle, the fan blade 42 on the right side of the rotating wheel 1 is parallel to the fan blade 42 on the left side, and when the fluid passes through the area between the rotating wheels 1 arranged in parallel, the left fan blade 42 and the right fan blade 42 driven by the rotating wheel keep the same direction (the same direction as the upper direction or the same direction as the lower direction in fig. 3) of the force, so that the angle formed by connecting the fan blade 42 and the resisting rod 4323 is set to be an obtuse angle in this embodiment.

Referring to fig. 3, when the fan blade device 4 rotates over the upper chamfered column 3, the outward extending support rod 4323 is close to the chamfered column 3, the linear velocity is low, and the fan blade 42 on the fan blade device 4 is far away from the chamfered column 3, the linear velocity is high, so the chamfered column 3 supports against the support rod 4323, the support rod 4323 is limited to overturn, after the fan blade 42 completely overturns over the chamfered column 3, the support rod 4323 bypasses the chamfered column 3, and then the body of the fan blade 42 presses the torsion spring 4322 under the action of gravity, thereby completing the working process that the fan blade device 4 rotates over the upper chamfered column 3 to realize overturn and keep an inclined state. When the fan blade device 4 rotates through the lower chamfered column 3, the fan blade 42 will automatically turn over under the action of its own gravity, then the support rod 4323 presses the torsion spring 4322, and the inclined state is maintained under the action of the gravity of the fan blade 42 and the elastic force of the torsion spring 4322, and finally the working process that the fan blade device 4 rotates through the lower chamfered column 3 to turn over and maintain the inclined state is completed.

Furthermore, a pulley 4321 is disposed at an end of the fan blade 42 away from the fixing plate 41, the pulley 4321 contacts with the fixedly installed resisting plate 5, the resisting plate 5 is a linear plate body, and the linear plate body is matched with a motion track of the pulley 4321, the pulley 4321 prevents the fan blade 42 and the resisting plate 5 from generating an excessive friction force to consume excessive energy, the resisting plate 5 can limit the fan blade 42 to be in an inclined state, and the phenomenon that the fan blade 42 is excessively overturned to fail to receive fluid kinetic energy due to excessive fluid power is avoided.

As described above, the embodiment of the present invention is not limited to the embodiment described in the specification and the embodiment, and the auxiliary device may be controlled by an intelligent control or a hall control. The above embodiments and the specific parameters in the embodiments are only for the purpose of clearly expressing the verification process of the utility model, and are not used to limit the patent protection scope of the present invention, the patent protection scope of the present invention is still subject to the claims, all the structural changes equivalent to the contents of the description and the drawings of the present invention should be included in the protection scope of the present invention.
