Description

Drive structure device for generating electricity through fluid power

The technical field is as follows:

the invention relates to the field of clean energy development and environmental protection, and mainly relates to a driving structure device for generating power by wind energy and water energy and other related applications.

Secondly, background art:

the utilization of the air and flowing water which move in nature does not need to be expensive, only needs initial investment with amount, and for a common horizontal axis wind power generation driving device with three large blades, the specification of the blades needs to be increased to obtain large electric energy, the longer the blades are, the larger the distance between the tail end of the fan blade and the circle center is, the larger the speed contrast between the tail end part of the blade and the part close to the circle center in moving fluid is, so that under the action of wind power with equal wind speed, the whole blade cannot be stressed to do work most effectively, particularly, the acting force exerted by the tail end part of the large blade when the blade is started is large, and the moment generated by one part of the tail end is large. Under the normal operation state, the acting force of the tail end part is very small and even counteracts, because the speed of the tail end part is too high, the acting force cannot be formed on the tail end part by the wind speed, and the problems of high manufacturing difficulty, relatively low efficiency and the like are solved.

Thirdly, the invention content:

the invention provides a novel vertical axis wind power generation driving structure device, namely a driving structure device for generating power through fluid power; each rectangular blade is arranged on the outermost side of the driving body in parallel, so that the maximum torque can be generated, the blades can be stressed uniformly in any state regardless of size, and more importantly, because the stress angle of the designed blades is not changed, most stress is formed by direct thrust of wind speed to the front direction of the blades, the power generation efficiency is obviously improved, the manufacturing cost is low, the installation and the transportation are easy, the harm to birds is reduced, and the like. The device mainly comprises a driving body frame with a fixed shaft, blades, a blade gear, a transmission shaft, a transmission gear, a yaw gear (integrated in size), a worm and gear reducing motor gear, a power supply, a direction sensor and a contactor. The power supply, the direction inductor and the contactor control the worm gear speed reducing motor to rotate backwards and forwards, the worm gear speed reducing motor is driven to control a yaw gear (a large gear with integrated size), the yaw gear (a small gear with integrated size) controls and connects one end transmission gear at two ends of a transmission shaft, and the other end transmission gear controls and connects a gear of the blade to control the rotation angle of the blade. The blades rotate for a circle along with the driving body, and simultaneously rotate for a half circle in a reverse direction relative to the deflection gear in a static state through gear transmission, so that the blades are always stressed in the front direction and in the side direction under the action of the moving fluid, namely the optimal working state is formed, and the power generation driving body continuously rotates under the power action of the moving fluid. When the fluid movement direction is changed, in order to synchronize the yaw gear with the fluid movement direction, a yaw gear is driven by a (left and right) direction swinging electric signal received by a power supply and an inductor, a linkage contact switch and a starting worm gear reduction motor (rotating in a backward and forward direction), and the driving body is always kept in the optimal working state when the movement fluid direction is changed by gear transmission and control of the rotating angle of each blade. In addition, the number of the blades can be designed according to actual use requirements, and can be 2, 3, 4 or N, but the included angles between the transmission shafts are ensured to be equal, and the deflection angles of the blades are kept consistent when each installed blade rotates to the same position. In the working process of the driving device, in order to reduce the working resistance of the driving body caused by the reverse rotation of the driving blades, the blades can be designed into blades which can generate a stress rotation form under the action of the motion fluid, namely, two sides of the rotating shaft of the same surface of the blades generate different stresses under the action of the motion fluid, so that the blades are stressed and rotated.

The combined type blade structure device is applied to wind power generation driving; it is composed of central axle, composite material leaf and upper and lower (sealed) edges. The blades are made of composite materials, one side of each blade is provided with a slope circle and the edges of the upper and lower sealing plates form two corresponding surfaces, and the acting force of the side (surface) with the slope circle and the side with the upper and lower edges is relatively small under the action of wind power, so that the self-rotation of the blades under stress is realized.

The power generation driving body rotates by half a whole design that the water level is higher than the flowing water level, and the blades are pushed along with the flowing water so that the new hydroelectric power generation driving operation works.

The device is applied to the driving of sea tidal power generation; firstly, enclosing the sea into two adjacent areas with small area difference, building a concave-groove seawater acceleration port on an adjacent public seawall dam for installing a newly designed power generation driving device, and respectively designing a water increasing port and a water discharging port in the two areas at two sides, wherein when the sea is in a long tide and the water level line of the sea reaches or exceeds the water level of a water increasing area, the water increasing port is automatically opened for water supplement; when the sea falls into the tide and the sea water level line is equal to the water level line of the water increasing area, closing the water increasing port; when the sea water level line is equal to or lower than the water level line of the water falling area, automatically opening the water falling port for draining water; when the ocean water level line is equal to the water level line of the water falling area, the water falling port is automatically closed, tide rises and falls, and the cycle is reciprocating, the driving structure device of hydrodynamic power generation designed above is designed and arranged at the bottom of the water outlet accelerating port according to the horizontal form of the axis of the blade rotating shaft, the yaw (gear) direction is fixed in the inclined direction of the concave channel water flow and is designed at the inner sides of two ends of the rotating shaft of the driving body, namely, the lower edge of the blade rotating to the rotating central axis of the driving body vertical to the water flow direction is always in front stress, and the upper edge of the blade rotating to the rotating central axis of the driving body is always in side stress, namely, the optimal working state is kept.

The fifth embodiment is as follows:

fig. 1 is an elevational view of the hydrodynamically generated drive arrangement of the present disclosure. The 4 blade frames are connected into a whole by 90 degrees in an intersecting way to form a rotatable driving body, and a fixed shaft is arranged in the middle of the rotatable driving body. FIG. 2 is a top view of FIG. 1, showing the rotation angle variation of the blades under the action of the yaw gear through the gear transmission and the force analysis when the blades rotate to different positions in the figure under the action of the moving fluid. The direction indicated by the central arrow in the figure is the direction of movement of the fluid, i.e. the yaw direction of the hydrodynamically generated drive arrangement herein. When the moving fluid moves in the direction of the arrow in the figure, the point A and the point B are positioned on the axis which forms 90 degrees in the moving direction of the fluid, the angle of the blade at the point A and the position at the point A are subjected to the largest acting force, the angle of the blade at the point B and the acting force of the blade at the point B are the smallest, the blade and the driving body start to apply work in the clockwise direction from the point B to the point G with an included angle of about 45 degrees of the circle center, and the force is gradually increased along with the gradual increase of the angles of the driving body and the blade, and is the largest when reaching the point C, the point E and the point A; similarly, the stress is gradually reduced to the H point, the D point and the F point. From point F to point B, point G is substantially equal to the reverse operation, at which point the blade angle is substantially in the direction of the moving fluid, with the reverse force appearing to be minimal. Therefore, under the action of the motion fluid, when the blade rotates from the A position to the B position along with the driving body, the driving body rotates 180 degrees, and the rotation angle of the blade is changed to 90 degrees at the same time; that is, the driver rotates 360 degrees in one turn, and the blades rotate 180 degrees in the opposite direction, so that the driver can rotate under the action of the moving fluid, and the optimal working state shown in fig. 2 is realized. If the blades installed by the driving body reach A, B two positions with opposite angle directions, the driving body rotates in the counterclockwise direction, and the blades rotate in the clockwise direction. Fig. 3 shows blades, transmission shaft, gears with blades, transmission gear, yaw gear, gear for worm gear and gear motor, inductor and contactor, and power source and fixed shaft. The tooth surface turning angle is controlled by the ninthly power supply, sensor and contactor on the fixed shaft, worm gear and worm reducing motor to rotate backwards and forwards to drive the gear of worm gear and worm reducing motor, yaw gear with the fixed shaft as rotation shaft, gear on the yaw gear, and other gear controller to control the gear of blades. According to the working principle described in fig. 2, under the condition that the number of teeth of each transmission gear is the same, the number of teeth of the (small) yaw gear is half of the number of teeth of the gear connecting the blades, so that the blades rotate in the reverse direction for a half circle while the yaw gear rotates for a circle. Similarly, when the yaw gear is relatively static (does not rotate), the driving body rotates for one circle, and the blades also rotate reversely for half a circle, so that the optimal working state is completed and the optimal working state can be always kept. And the angles of the blades are kept consistent when each blade rotates to the same position (shown in fig. 2), namely, the optimal working state is formed, the blades are always stressed in the front direction and the side direction when the driving body rotates to the point A, the rotation period of the blades 3/4 is always stressed in the same rotation direction, and the reverse stress of the blade 1/4 is basically the side direction of the blade, so that each blade is stressed in sequence, and the power generation driving body rotates under the power action of the moving fluid. When the fluid movement direction changes, that is, when the direction indicated by the middle arrow is deviated to the left as shown in fig. 2, the left induction switch in the direction sensor in the structure of fig. 3 is closed, and the yaw gear rotates in the reverse direction through the power supply, the linkage contactor and the start worm gear speed reduction motor, otherwise, the yaw gear rotates in the forward direction. When the direction (movement of fluid) indicated by the arrow in the middle is not changed, the motor is halted, the yaw gear and the movement direction of the fluid are always kept synchronous, and the optimal working state is always kept, and the yaw control structure is also disclosed. Because the yawing of this structure is laborsaving easy, in the yaw control structure use of small-size fluid power electricity generation, the power of worm gear motor is less, therefore does not need to use the contactor, and the (left and right) inductive switch in the direction inductor can directly replace the contactor, specifically still need to design according to actual conditions.

Two sides (AB) of the central shaft of the blade are manufactured into a keel and a plane to form two corresponding surfaces, the back of the plane is connected with the keel, and one end of the keel and one side of the plane are connected with the central shaft to form a whole. Under the action of wind force, the stress of the concave surface is greater than that of the plane, so that the blades are stressed to rotate.

FIG. 9 is a cross-sectional view along the direction AB of FIG. 8, in which the first is the upper and lower edges of the blade, the second is the central axis of the blade, and the third is the composite blade. The blade is manufactured into two surfaces by using composite materials, one side of each surface is provided with a slope circle and the upper and lower sealing plate edges to form two corresponding surfaces, and the acting force of one side of the rotating shaft of the blade, which is provided with the slope circle and the upper and lower edges is relatively less under the action of wind power, is relatively smaller, so that the self-rotation of the blade under stress is realized.

Fig. 15 is a driving elevation view of sail type blade vertical axis wind power generation.

FIG. 13, FIG. 14, FIG. 15 are vertical axial wind power driving elevation views of the hydrokinetic energy generating driving structure apparatus of the present disclosure; the above working principle described in fig. 2, the structure method described in fig. 3, and the rotation blade structure described in fig. 4 to 12, the two blades are connected together to form a rotatable driving body, and a fixed shaft is provided in the middle. The transmission shaft is arranged in the upper cross beam connected with the transmission shaft, the transmission gears are arranged at the two ends of the cross beam to control the blade gears, and the transmission gear, the yaw gear (integrated in size), the worm gear and worm reduction motor gear, the direction sensor and the contactor (power supply) are arranged in the middle of the two connected blade cross beams. When wind comes, a yaw gear is driven by a power supply, a wind direction electric signal received by an inductor, a linkage contact switch and a starting worm gear speed reducing motor (rotating in a forward and reverse direction), the optimal working state is kept for operation through gear transmission and control of the rotating angle of each blade, and the novel vertical axis wind power generation driving is formed. And finally, the rotating driving body drives the generator to generate electricity through the accelerating gear. In the practical application process, 2 to 4 blades are reasonable. In addition, the 'sail type' blade designed in the specification is more suitable for manufacturing a large-scale wind power drive, the structure of the blade is made of a metal frame and large-area canvas (umbrella cloth), the blade is large, the weight can be designed to be lighter, and the blade has the characteristics of larger specification and slower rotating speed as compared with the existing three large-blade power generation drives. But the vertical axis wind power generation drive designed herein, the rectangular blade has larger stress area, thus can produce the maximum moment, and the blade design can be stressed evenly no matter what size, under what state, more importantly, because the designed blade does not change the stress angle in sections, form most stress and come from the direct thrust of the wind speed to the front direction of the blade, therefore the generating efficiency is improved very obviously, and the manufacturing cost is low, the installation, the transportation are easy, reduce the harm to birds, etc., it is that its yaw operation is very ingenious, easy, it has more advantages than the existing yaw that three big blades of horizontal axis generate electricity and drive.

Fig. 16 is a schematic cross-sectional view of the hydrokinetic power generation driving structure device applied to a hydroelectric power generation driving device (a cross-sectional view of a concave groove dam). In the figure, 6 blades are designed, A is a circular-structure power generation driving body (a transmission shaft, a transmission gear and a yaw gear are arranged in the circular-structure power generation driving body, the transmission shaft, the transmission gear and the yaw gear are arranged in the circular-structure power generation driving body, B is the blades, C is a power generator with an accelerating gear, D is a seabed (river bed), E is a concrete concave groove arc-shaped groove bottom, and F is a concrete concave groove dam with a groove. Due to the height difference of the water levels on the two sides of the concave tank dam, the blades are pushed along with the flow of water, so that the driving body continuously rotates to drive the accelerating gear generator to generate electricity. Its main features are slow rotation speed and high thrust. Firstly, selecting favorable terrain to cofferdam, building a groove water outlet acceleration port, arranging the designed fluid power generation driving structure device at the bottom of the water outlet acceleration port in a horizontal mode of the axis of a blade rotating shaft, fixing the yaw (gear) direction in the inclined direction of groove water flow, and designing the device at the inner sides of two ends of a driving body rotating shaft, (the yaw gear at each end controls 3 blades), namely the yaw gear is fixed at the inner sides of two ends of the driving body rotating shaft. Each blade rotates to the blade angle at the top as shown in fig. 16, and is set to be maintained to the first position (yaw direction), that is, the lower edge of the blade on the rotating central axis of the driving body which is perpendicular to the water flow direction always bears the force in the front direction, and the upper edge always bears the force in the side direction, that is, the optimal working state is maintained. The power generation driving body rotates by half a height higher than the flowing water level. The new hydroelectric drive operation is operated as the water flow pushes the blades. The device is applied to the driving of sea tidal power generation; firstly, enclosing the sea into two adjacent areas with small area difference, building a concave-groove seawater acceleration port on an adjacent public seawall dam for installing a newly designed power generation driving device, and respectively designing a water increasing port and a water discharging port in the two areas at two sides, wherein when the sea is in a long tide and the water level line of the sea reaches or exceeds the water level of a water increasing area, the water increasing port is automatically opened for water supplement; when the sea falls into the tide and the sea water level line is equal to the water level line of the water increasing area, closing the water increasing port; when the sea water level line is equal to or lower than the water level line of the water falling area, automatically opening the water falling port for draining water; when the ocean water level line is equal to the water level line of the water falling area, the water falling port is automatically closed, tide rises and falls, and the driving structure device for hydrodynamic power generation is circularly reciprocated, and is arranged at the bottom of the water outlet accelerating port according to the horizontal form design of the axis of the rotating shaft of the blade, the direction of the yaw (gear) is fixed in the inclined direction of the concave channel water flow and is arranged at the inner sides of two ends of the rotating shaft of the driving body, (the yaw gear at each end controls 3 blades), namely, the yaw gear is fixed at the inner sides of two ends of the rotating shaft of the driving body. Each blade rotates to the blade angle at the top as shown in fig. 16, and is set to be maintained to the first position (yaw direction), that is, the lower edge of the blade on the rotating central axis of the driving body which is perpendicular to the water flow direction always bears the force in the front direction, and the upper edge always bears the force in the side direction, that is, the optimal working state is maintained. The power generation driving body rotates by half a height higher than the flowing water level. As the seawater flow pushes the blades, a new tidal power drive operation is made to work. The conventional hydroelectric generation is that water is firstly stored to increase the height difference of water level to obtain a certain amount of potential energy, so as to impact a water turbine to drive power generation. The electric power can be generated under the action of natural water flow. The method is mainly characterized in that favorable terrain is selected; the inland is located in the great rivers, and can be conveniently developed and utilized according to local conditions. The tidal power generation can be uninterrupted, and the device is pollution-free, wide in development range and the like. As long as the coastline under certain conditions is obtained, inexhaustible new energy can be obtained through design. The map shows the Shandong Rushan mountain, the geographical conditions are very excellent, and two natural tidal power stations are almost arranged on two sides of the coastal tourism vacation area of the Darunshan mountain. Two large tidal power stations can be built with little sea surrounding investment and without destroying the existing natural environment.

Under the effect of water flow, the structure is designed to be reasonable with 4 to 8 blades. The reason is that: in the same situation, the fluid with higher density generates higher kinetic energy during movement, the continuity of the acting force is strong, and particularly, the number of blades and the structural form of the blades are designed according to the actual situation during use. For the design of the blade, i propose to give priority to the flat surface for the following reasons: in the operation process of the structure, the blades are basically in a lateral water inlet and outlet state, the density of water is higher than that of air, and the thrust generated during movement is very high, so that the design of the power-assisted self-rotating blades is of little significance. In addition, in the application process of the hydroelectric power generation drive, two corresponding hydroelectric power generator drives are designed and installed in each concrete concave groove, so that the design can increase the benefit and reduce the cost.
