Abstract

A sail windmill includes at least two separated towers, sail frames (20) mounted on each tower, an endless cable (40, 83, 94) connecting adjacent towers, and plural sails (60, 85, 95) having windward angle arranged on the cable. Each sail frame includes a main shaft (21, 81, 93) mounted on the tower and a drive wheel (22, 82, 92) secured to the mail shaft. There is a gear engaged driving mechanism between the cable and the wheel. The sails propel the cable to drive the wheel by means of the gear engaged driving mechanism, and therefore the wheel drives the main shaft to rotate. The sails that arranged between two towers considerably increasethe wind area. This sail windmill can generate electric energy at low wind power and has the advantages of high efficiency and low cost.

Description

Specification chain wind turbine and method for utilizing wind output power

#细 or

[1] The present invention relates to a wind power plant, and more particularly to a chain wind turbine that can be used for wind power generation and a method of outputting power using wind power.

[2] Today, with petrochemicals and coal-fired energy sources fading, wind power has become one of the key directions for human energy development. The data show that the total amount of wind energy resources that can be developed globally is about many times the total amount of human energy demand. The richness of wind energy and natural regenerability are the most attractive reasons.

[3] Wind power technology originated in Europe, and Denmark, the Netherlands, Germany and other countries have been developing and advocating wind power for more than 20 years. Since the birth of wind power technology, it has undergone continuous improvement, and has evolved into a relatively mature horizontal axis, three-blade, conical tubular tower and other structural forms.

[4] The current large-scale wind turbines are usually in the form of horizontal-axis wind turbines, which are mainly composed of towers, wind wheels, gearboxes (acceleration gearboxes), generators, wind turbines, control systems and other components. The role of the wind wheel is to convert wind energy into mechanical energy. It consists of a vane with good gas flow performance on the axle. The low-speed rotating wind turbine accelerates the gearbox through the transmission mechanism, and then transmits the power to the generator. The wind wheel is supported by a tall tower. Since the wind direction changes frequently, in order to use the wind energy effectively, it is necessary to have a windward device that automatically winds up. There are generally three types of existing wind-driven devices, the first one is controlled by a tail rudder; the second type is controlled by a steering wheel; and the third is a wind-driven sensor combined with a servo motor to realize wind. Use the wind device to push the wind wheel so that it always faces the windward side.

[5] In the case of a horizontal-axis wind turbine, the lift generated by the airflow (wind) always pushes the blades of the rotor around the central axis. At the same wind speed, the magnitude of the lift will not change.

As shown in FIG. 1 to FIG. 6, in the first embodiment of the chain wind turbine of the present invention and the method for outputting power using wind power, the chain wind turbine includes two towers 10 which are disposed at a distance apart. a chain sail frame 20 mounted on the tower 10, a closed chain 40 connecting the adjacent chain sail frames 20, and a plurality of chain cables 40 mounted on the chain 40 Chain sail 60. The wind-driven chain sail 60 drives the chain 40 to rotate, thereby driving the main vertical shaft 21 on the chain sail 20 to rotate, and the main vertical shaft 21 can be connected with the speed increaser of the wind power generator to drive the wind power generator to generate electricity.

[40] The tower 10 can be selected from various existing towers 10, and the main vertical shaft 21 of the chain sail frame 20 is rotatably mounted on the tower 10 by bearings or the like. The speed line between the adjacent two towers 10 is preferably perpendicular to the main wind direction, so that wind energy can be better utilized.

[41] The chain sail frame 20 is mounted on the tower 10 and includes a rotatable main vertical shaft 21 and a drive plate 22 fixedly mounted on the main vertical shaft 21. An engagement transmission mechanism is disposed between the drive plate 22 and the chain 40. During the rotation of the chain 40, the drive plate 22 is rotated by the meshing transmission mechanism to drive the main vertical shaft 21 to rotate. A power output wheel 23 is fixedly coupled to the main vertical shaft 21 for connecting the speed increaser of the wind power generator to output power to the wind power generator for power generation.

As shown in FIG. 3, the meshing transmission mechanism includes a notch 221 opened at the periphery of the drive plate 22, and a lands 50 connecting the chain sail 60 and the chain 40. After the wind-driven chain sail 60 drives the chain 40 to rotate, and the position of the connecting plate 50 reaches the notch 221, the connecting plate 50 is snapped into the position of the notch 221, and then the wind continues to push the chain 40 to continue to rotate, so that the connection is made. The disk 50 pushes the drive disk 22 to rotate, thereby driving the main vertical shaft 21 to rotate, and then outputting through the power output wheel 23. It will be appreciated that the meshing transmission mechanism may also include other forms of meshing transmission, such as by extending the lever outwardly on the drive plate 22, using the chain sail 60 to directly push the lever to drive the drive disk 22 to rotate, or the like. Further, on the circumference of the drive plate 22, a groove is formed to facilitate guiding of the chain 40.

In the present embodiment, the drive disk 22 includes an upper disk and a lower disk, and the chain cable 40 includes an upper chain 40 and a lower chain 40, respectively. The meshing transmission mechanism can be set on the upper and lower plates at the same time, or alternatively.

A plurality of chain sails 60 are disposed between the upper chain 40 and the lower chain 40, and the number of the chain sails 60 is determined according to the distance between the two towers 10 and the length of the circumference of the drive disk 22. In the present embodiment, the chain sail 60 is a windsurfing board, including a sail 61, and a strut 62 vertically fixed in the middle of the sail 61. The sail 61 is made of a thin plate of various materials having a certain strength, and a beam is attached to the upper and lower sides of the pillar 62 for fixing the sail 6 1; or the canvas is selected, and the canvas is fixed on the frame, and then the pillar is used. 62 is mounted between the upper chain 40 and the lower chain 40. The upper and lower ends of the pillar 62 are connected to the upper chain 40 and the lower chain 40 via the upper land 50 and the lower land 50, respectively. Each of the lands 50 includes a disk-shaped body 51, a mounting hole 52 opened in the middle of the disk-shaped body 51, and an arcuate guide 53 opened on the disk-shaped body 51. Both ends of the strut 62 are mounted by bearings In the mounting hole 52, the chain sail 60 can be rotated; and the chain 40 is snap-fitted into the guide rail 53, thereby fixedly connecting the chain sail 60 to the chain 40, and the chain sail 40 drives the chain 40 to rotate. In order to better fix the chain cable 40 in the lands 50, it is also possible to add a cover plate to close the lands 50; or to add barbs in the guide rails 53, thereby increasing the friction between the chain cables 40 and the guide rails 53, so that the chain The cable 40 is better connected to the lands 50.

[45] In order to control the rotation of the chain sail 60, the chain wind turbine is also provided with a steering mechanism. The steering mechanism includes a rotating gear 71 fixedly mounted on a lower side of the lower land 50 of each chain sail 60, a steering clutch 72 that controls rotation of the rotating gear 71, and a rotating gear 71 that is mounted on each of the main vertical shafts 21. Rotating steering gear.

In the present embodiment, the steering transmission includes a wind direction positioning gear 73 coaxially mounted with the main vertical shaft 21, a bridge planetary gear 74 meshing with the wind direction positioning gear 73, and a driving device for controlling the rotation of the driving wind direction positioning gear 73. 75. The bridge planetary gear 74 meshes with the rotating gear 71 to drive the chain sail 60 to rotate. The driving device 75 may include a wind direction sensor and a servo motor that outputs power according to the wind direction sensor. The output of the servo motor meshes with the wind direction positioning gear 73, and the drive wind direction positioning gear 73 rotates. Of course, the drive unit 75 can also be selected from other existing structural forms, and the rotation of the gear is adjusted according to the wind direction. In the present embodiment, the bridge planetary gears 74 are uniformly distributed on the same circumference, and are mounted on the main vertical shaft 21 through the upper bracket 76 and the lower bracket 77.

[47] When the wind direction has not changed, the servo motor stops outputting power, the wind direction positioning gear 73 cannot rotate, the bridge planetary gear 74 cannot rotate, and the chain sail 60 rotates to the position of the bridge planetary gear 74, chain The clutch on the sail 60 releases the lock of the chain sail 60, and its rotating gear 71 meshes with the bridge planetary gear 74, causing the rotating gear 71 to rotate, causing the chain sail 60 to rotate 90 degrees to realize the steering of the chain sail 60. When the wind direction sensor detects a change in the wind direction, and when the chain sail 60 rotates to the position of the bridge gear 74, the servo motor starts to act, causing the wind direction positioning gear 73 to rotate, and simultaneously drives the bridge planetary gear 74 to rotate. The rotation speed of the servo motor is adjusted so that the wind direction positioning gear 73, the bridge planetary gear 74, and the rotation gear 71 cooperate to drive the chain sail 60 to rotate at a certain angle to obtain a better wind angle.

As shown in FIG. 7, in the present embodiment, the steering clutch 72 includes a lever 722, a positioning rod 723, and a spring 724 in which the rotation pin 721 is mounted at an intermediate position. The positioning rod 723 is disposed at the end of the lever 722, and in the locked state 吋, is inserted into the positioning hole 712 of the rotating gear 71, thereby locking the rotating gear 71, locking the chain sail 60 . There are a plurality of positioning holes 712 which may be evenly distributed on the side of the rotating gear 71 close to the positioning rod 723. It can be understood that the positioning rod 723 can also be directly inserted between the teeth of the rotating gear 71 to restrict the rotation of the rotating gear 71, and the positioning hole is omitted. A roller 725 is provided at the other end of the lever 722, and the spring 724 presses the side end of the lever 722. When the chain sail 60 is rotated to the position of the notch 221 of the drive plate 22, the lands 50 of the chain sail 60 are snapped into the notch 221, and the roller 725 of the lever 722 is pushed by the fixed cam 222 formed on the surface of the drive plate 22. When the upward movement, the positioning rod 721 of the other end of the lever 722 is moved downward to disengage from the positioning hole 712 of the rotating gear 71, and the locking of the rotating gear 71 is released, so that the rotating gear 71 can rotate, and the strut 62 of the chain sail 60 is rotated. . When the chain sail 60 rotates away from the driving plate 22, under the elastic recovery of the spring 72 4 of the lever 722, the positioning rod 723 is pushed upward to re-lock into the positioning hole 7 12 of the rotating gear 71, thereby locking the chain again. Sail 60. Further, a directional fine adjustment gear 726 is further disposed on the pillar 62, and the angle of the pillar is finely adjusted by the motor.

[49] It can be understood that the steering clutch 72 can also be used in other forms. For example, the sensor detects the position where the chain sail 60 rotates to the notch 221, and sends a driving signal to drive the electromagnet to work, and the core of the electromagnet is driven out of the position of the rotating gear 71. Between the teeth of the hole 712 or the rotating gear 71, the locking of the chain sail 60 is released; when the chain sail 60 is rotated out of the driving plate 22, the electromagnet is de-energized, the core is reset, and the chain sail 60 is re-locked.

[50] As shown in FIG. 4, when the speed line of the two-chain sail frame 20 is perpendicular to the main wind direction, the shovel 61 installed on the first side has the same angle, and the sail 61 installed on the second side is 61. Having the same angle, and the angle of the first side of the sail 61 is 90 degrees to the angle of the second side of the sail 61. Thereby, the directions of the forces of the wind received by the side sails 61 are made uniform, and the chain 40 is pushed to rotate in the same direction. As shown, when the wind blows in the direction of arrow A toward the first side of the chain sail 60吋, the first side of the chain sail 60 receives a leftward thrust, causing the chain 40 to move to the left, after the wind passes the first side, Blowing toward the second side 吋, the second side of the chain sail 60 receives a rightward thrust, causing the chain 40 to move to the right, thereby causing the entire chain 40 to rotate. When the first side chain sail 60 is rotated to the position of the drive plate 22, the lands 50 of the chain sail 60 are snapped into the position of the notch 221 of the drive plate 22, so that under the action of the wind, the lands 50 push the drive plate 22 rotates to drive the main vertical shaft to rotate. At the same time, the steering clutch 72 is actuated such that the positioning lever 723 is disengaged from the inter-tooth position of the rotating gear 71, and the rotating gear 71 meshes with the bridge planetary gear 74, in the servo motor, the wind direction positioning gear 73, the bridge planetary gear 74, and the rotation. With the cooperation of the gear 71, the chain sail 60 is rotated exactly 90 degrees in the position where the chain sail 60 leaves the drive plate 22. Similarly, when the chain sail 60 on the second side reaches the drive plate 22 on the right side, the servo power on the right side The combination of the machine, the wind direction positioning gear 73, the bridge planetary gear 74 and the rotating gear 71 causes the chain sail 60 to rotate exactly 90 degrees when it leaves the drive disk 22 on the right side. Therefore, the chain sails 60 on both sides have a good wind angle, and the chain 40 is rotated in the same direction.

[51] As shown in FIG. 5, when the speed line of the two-chain sail frame 20 is parallel to the main wind direction, the angle of the first side of the sail 61 is perpendicular to the direction of the wind, and the angle of the second side of the sail 61 is The wind directions are parallel, and when the chain sail 60 passes the drive disk 22, the chain sail 60 is rotated by 90 degrees in cooperation with the servo motor, the wind direction positioning gear 73, the bridge gear 74 and the rotating gear 71. The angle of the chain sail 60 effects the continuous rotation of the chain 40.

[52] As shown in FIG. 6, when the speed line of the two-chain sail frame 20 is at an angle to the main wind direction, the angle of the chain sail 60 on the first side is perpendicular to the direction of the wind, and the angle of the chain sail 60 on the second side. At an angle to the direction of the wind (for example, 90 degrees, 70 degrees, etc., the best angle can be obtained by testing). When the chain sail 60 passes the driving plate 22, the servo motor, the wind direction positioning gear 73, the bridge planetary gear 74 and the rotating gear 71 cooperate to rotate the chain sail 60 by a corresponding angle to convert the chain sail 60. Angle, the continuous rotation of the chain 40 is achieved.

[53] As shown in FIG. 11 (only the principle is shown in the figure), a plurality of driving disks 22 can be assembled on the same main vertical shaft 21 to form a series wind turbine, which can pass through the chain cables 40 on both sides. The chain sail 60 drives the corresponding drive plate 22 to rotate, and the power shaft is rotated by the same vertical shaft 21, and the speed increaser of the wind power generator is driven to rotate, and the power is output to the wind power generator for power generation.

[54] In the second embodiment of the chain sail wind turbine of the present invention, the difference from the first embodiment is that the structural form of the steering transmission is different, and the other structures are basically similar to the first embodiment, so it is not like Said.

[55] In the present embodiment, the steering transmission includes a wind direction positioning gear mounted coaxially with the main vertical shaft, an internal gear meshed with the wind direction positioning wheel, an external gear meshed with the rotating gear, and a chain coupling the internal gear and the external gear Transmission structure. The chain transmission structure includes an inner sprocket that rotates coaxially with the inner gear, an outer sprocket that rotates coaxially with the outer gear, and a chain that connects the inner sprocket and the outer sprocket. The number of teeth of the outer gear is twice the number of teeth of the inner gear. The wind direction positioning gear can be rotated forward, reversed or not rotated under the control of the steering transmission to control the rotation angle of the rotating gear of the chain sail, and realize the control of the rotation angle of the chain sail. Specifically, when the wind direction does not change, the wind direction positioning gear does not rotate; when the wind direction changes, the rotation speed of the rotating gear is controlled by controlling the rotation speed of the wind direction positioning gear and the rotation direction, thereby adjusting the rotation angle of the chain sail. Degree.

[56] In this embodiment, when the wind direction is not changed, the chain sail is rotated to the position of the driving plate, the rotating gear meshes with the external gear, and after the chain sail rotates 180 degrees around the driving plate, the rotating gear meshes with the external gear. , causing the chain sail to rotate 90 degrees, thus changing the windward angle of the chain sail.

[0] As shown in FIG. 8 to FIG. 10, it is a third embodiment of the chain wind turbine of the present invention, which is applicable to the tuyere area, for example, a directional wind having a relatively similar wind direction, such as a difference between the front side and the front side. 20°. The chain wind turbine includes two towers spaced apart at a distance, a chain sail mounted on the tower, a closed chain connecting the adjacent chain sails, and a plurality of chain sails mounted on the chain.

As described in the first embodiment, the tower can be selected from various existing towers, and the main vertical shaft of the chain sail is rotatably mounted on the tower by bearings or the like. The speed line between two adjacent towers is preferably perpendicular to the main wind direction so that wind energy can be better utilized.

[59] The chain sail is mounted on the tower and includes a rotatable main vertical shaft 81 and a drive plate 82 fixedly mounted to the main vertical shaft 81. An engaging transmission mechanism is disposed between the driving plate 82 and the chain 83.

A power output wheel is fixedly connected to the main vertical shaft 81, and the speed increaser for the wind power generator is connected, and the power is output to the wind generator to generate electricity.

As shown in Fig. 8, the meshing transmission mechanism includes a notch 84 opened at the periphery of the drive plate 82, and a lands 86 connecting the chain sail 85 and the chain 83. After the wind-driven chain sail 85 drives the chain 83 to rotate, and drives the connecting plate 86 to reach the position of the notch 84, the connecting plate 86 snaps into the position of the notch 84. Thereafter, the wind continues to push the chain 83 to continue to rotate, so that the connection is made. The disk 86 pushes the drive disk 82 to rotate, thereby causing the main vertical shaft 81 to rotate and then output through the power output wheel. It will be appreciated that the meshing transmission mechanism may also include other forms of meshing transmission, such as by extending the lever outwardly on the drive plate, directing the lever to drive the drive disk to rotate, or the like. Further, a groove is formed on the circumference of the driving plate to guide the chain.

In the present embodiment, the drive disk 82 includes an upper disk and a lower disk, and the chain cable includes an upper chain and a lower chain. The meshing transmission mechanism can be set on the upper and lower plates at the same time, or alternatively.

[62] A plurality of chain sails are arranged between the upper and lower chains, and the number of chain sails is determined by the distance between the two towers. In this embodiment, the chain sail 85 is a canvas chain sail, including a pole 851, a canvas 852, and a connection. Chain 853 and tie rod 854. One side of the canvas 852 is attached to the strut 851, and the strut 851 is mounted on the lands 86 by bearings or the like, thereby rotatably mounting the strut 851 between the upper and lower links. The tie rod 85 4 can be made of an elastic material, and the other side of the canvas 852 is attached to the tie rod 854. The canvas 852 is pulled up by the pulling of the rod 851 and the rod 854. The connecting chain 853 is two, including an upper connecting chain and a lower connecting chain. One end of the upper connecting chain is connected to the upper end of the tie rod 854, and the other end is connected to the upper chain. One end of the lower connecting chain is connected to the lower end of the tie rod 854, and the other end is connected to the lower chain. The connecting chain 853 can be directly connected to the chain 83; or can be connected by a rotatable second strut 855, as shown in Fig. 9, the second strut 855 is rotatably connected to the upper and lower cables via the connecting disc 86. Between the links; then the connecting chain 853 is directly fixedly attached to the second strut 855. The connecting chain 853 can be made of a steel cable, a rope or the like so as to be movable to pull one side of the canvas so that the canvas is subjected to wind and forms a wind bag.

In the present embodiment, the length of the strut 851 is greater than the length of the tie rod 854. Correspondingly, the canvas 852 is formed in a trapezoidal shape, so that the canvas 852 is swung to the left and right sides with the chain cable 83 as the axis.

[64] As shown in FIG. 9, one side of the canvas 852 is fixed between the upper chain and the lower chain as a fixed end; the other side is connected to the upper and lower chains through the upper connecting chain and the lower connecting chain. On the cable, it is the active end. As shown in Fig. 10, the wind is blown from one side of the chain 83, and the canvas 852 is subjected to the wind, pushing the movable end of the canvas 852 to open, thereby generating the power for pushing the canvas 852 to one side, as shown in Fig. 10 The direction indicated by the arrow AA; under the driving of the canvas 852, the upper chain and the lower chain move to the same side. When the chain sail near the side of the wind source is rotated to the position of the drive plate 82, the splicing plate 86 of the chain sails snaps into the position of the notch 84 of the drive plate 82, and under the continuation of the wind force, the lands 86 pushes the drive plate. 82 rotates to drive the main vertical shaft 81 to rotate. When the chain sail is turned to the side away from the wind source, the canvas 852 is subjected to the wind, and the movable end of the canvas 852 is pushed open, thereby generating the power for pushing the chain 83 to move to one side, as shown by the hollow arrow BB in FIG. direction. The directions of rotation of the links 83 on both sides are continuous, so that the chain 83 rotates between the two towers and drives the drive disk 82 to rotate, thereby converting the wind into a mechanical energy output.

[65] In this embodiment, since the wind direction is relatively stable, the characteristics of the canvas itself being deflected by the wind are utilized to obtain a better windward angle, and the steering transmission device of the first embodiment is omitted, which has the advantages of simple structure and low cost. The advantages.

12-14 is a schematic view of the structure of the present invention, which is different from the foregoing embodiment in the following embodiments: Power output The axis of the wheel 23, the main vertical shaft 21, the rotating shaft of the generator, and the like are all vertically disposed, and in the present embodiment, the axes of the driving disk 92, the power output wheel, the main vertical shaft 93, the rotating shaft 97 of the generator 96, and the like are horizontally disposed. Other configurations may be adjusted in accordance with the configurations of the first to third embodiments described above. As shown in FIG. 12, there are two driving discs 92, which are installed horizontally on the main vertical shaft 93, and the chain drives 94 are disposed between the two driving discs 92 on the same side, and the chain sails 95 are spanned in two. Between the links 94, as the wind receiving member, the wind force is used to push the chain 94 to rotate, thereby driving the driving plate 92 to rotate, and the rotating shaft 97 of the generator 96 is also horizontally disposed, and the driving disk 92 drives the power output wheel to rotate to generate electricity. The machine shaft 97 rotates to generate electricity.

[67] It can be understood that two sets of driving discs 92 can also be mounted on the main vertical shaft 93, as shown in Figs. 13, 14, thereby increasing the power input of the main vertical shaft 93, thereby improving power generation efficiency. The driving discs 92 are staggered and mounted on the main vertical shafts 93. The two sets of chain sails 95 drive the respective chain cables 94 to rotate, thereby driving the respective driving discs 92 to rotate. The two sets of movements do not affect each other, and are driven by the driving discs 92. The rotation of the rotating shaft 97 of the motor 96 greatly increases the utilization efficiency of the wind, and can still drive the motor shaft 97 to generate electricity at a lower wind speed.
