[0034] All terms used in the present disclosure have the same meanings as those understood by those of ordinary skill in the art to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such herein.

[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0036] like Figures 1 to 9As shown, the present disclosure provides a wind power photovoltaic combined power generation device, comprising: a mounting frame 1, on which a mounting shaft 101 is provided; a wind power rotating mechanism 2, which is rotatably arranged on the mounting shaft 101 and can be rotated around the axis of the mounting shaft 101 under the action of wind; a photovoltaic panel 3, which is connected to the top of the mounting frame 1 and can be rotated between a first position at an acute angle to the axis of the mounting shaft 101 and a second position at a right angle to the axis of the mounting shaft 101; a connecting mechanism 4, a first end of the connecting mechanism 4 is connected to the photovoltaic panel 3, a second end of the connecting mechanism 4 is radially movably connected to the wind power rotating mechanism 2, and the second end of the connecting mechanism 4 can make a centrifugal motion relative to the mounting shaft 101 when the wind power rotating mechanism 2 rotates, so as to pull the photovoltaic panel 3 to rotate from the first position to the second position; and a reset mechanism 5, which is installed on the wind power rotating mechanism 2, and the reset mechanism 5 is configured to drive the photovoltaic panel 3 to rotate to the first position through the connecting mechanism 4 after the centrifugal motion of the second end of the connecting mechanism 4 disappears.

[0037] Specifically, the photovoltaic panel 3 is rotatably connected to the top of the mounting frame 1, and when the device is put into use, the mounting axis 101 is usually placed vertically. When the wind force is small, the rotation speed of the wind-driven rotating mechanism 2 around the axis of the installation axis 101 is small under the action of wind force, and the radial displacement of the second end of the connecting mechanism 4 relative to the installation axis 101 that can be generated in the centrifugal movement is also small. Correspondingly, the first end of the connecting mechanism 4 can only pull the photovoltaic panel 3 to rotate a small angle, and the photovoltaic panel 3 is closer to the first position at an acute angle to the vertical direction (i.e., the axis direction of the installation axis 101). At this time, the photovoltaic panel 3 is inclined and arranged at the top of the installation frame 1, which is conducive to receiving sunlight exposure; when the wind force is large, the rotation speed of the wind-driven rotating mechanism 2 around the axis of the installation axis 101 is large under the action of wind force, and the radial displacement of the second end of the connecting mechanism 4 relative to the installation axis 101 that can be generated in the centrifugal movement is also large. Correspondingly, the first end of the connecting mechanism 4 can pull the photovoltaic panel 3 to rotate a large angle. At this time, the photovoltaic panel 3 is closer to the second position at a right angle to the vertical direction, that is, the photovoltaic panel 3 tends to fall over, which effectively reduces the wind-receiving area of ​​the photovoltaic panel 3 and avoids the phenomenon of the device overturning under the action of large wind force. When the wind force gradually decreases, the reset mechanism 5 can push the second end of the connecting mechanism 4 to move radially inward. Correspondingly, the first end of the connecting mechanism 4 drives the photovoltaic panel 3 to rotate toward the first position, so that when there is no wind or the wind force is small, a certain angle is maintained between the photovoltaic panel 3 and the vertical direction, so that the photovoltaic panel 3 can be tilted on the top of the mounting frame 1, which is conducive to receiving light and improving the power generation efficiency.

[0038] In actual use, it is found that due to the influence of the cold and hot air convection caused by direct sunlight at noon, the wind force is usually the strongest during the noon time period. At this time, the wind-driven rotating mechanism 2 in the present device rotates at a faster speed, which can drive the second end of the connecting mechanism 4 to produce a larger radial displacement relative to the mounting shaft 101 in the centrifugal motion, and accordingly makes the photovoltaic panel 3 closer to the second position perpendicular to the vertical direction. While avoiding the device from being overturned by the wind, it is also more conducive to the photovoltaic panel 3 receiving direct sunlight at noon, thereby improving the power generation efficiency of the photovoltaic panel 3 during the noon time period; in other time periods when the wind force is relatively small, the sunlight is obliquely irradiated. At this time, the wind-driven rotating mechanism 2 in the present device rotates at a relatively slow speed, so that the photovoltaic panel 3 can be tiltedly set on the top of the mounting frame 1, which is conducive to receiving the obliquely irradiated sunlight.

[0039] In some embodiments, the mounting frame 1 includes a base 104 for placing the mounting axis 101, and a plurality of support columns 105 surrounding and parallel to the mounting axis 101 are provided on the base 104, and a support ring 106 is provided at the top of the support column 105, and the photovoltaic panel 3 is connected to a connecting rod 108 provided on the support ring 106, and the first side of the photovoltaic panel 3 is hinged to the end of the connecting rod 108 away from the support ring 106, and the second side of the photovoltaic panel 3 opposite to the first end of the connecting mechanism 4 is hinged. In the initial state, the second side of the photovoltaic panel 3 is higher than the first side, so that it maintains an inclined posture that is conducive to receiving light, and when the first end of the connecting mechanism 4 pulls the second side of the photovoltaic panel 3 to rotate downward, the photovoltaic panel 3 tends to fall down to reduce the wind receiving area. At the same time, the support ring 106 has a circular hole in the middle for the connecting mechanism 4 to pass through, so that the wind power rotation mechanism 2 located below the support ring 106 can indirectly drive the photovoltaic panel 3 to rotate through the connecting mechanism 4.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the wind power rotating mechanism 2 includes a steering sleeve 201 rotatably sleeved on the mounting shaft 101 , and a plurality of power generation blades 202 are distributed on the outer periphery of the steering sleeve 201 .

[0041] Specifically, the steering sleeve 201 and the plurality of power-generating blades 202 of the wind-driven rotating mechanism 2 are evenly distributed along the circumference of the installation shaft 101, so as to avoid the wind-driven rotating mechanism 2 generating an unbalanced torque during the rotation process, which causes the installation frame 1 to swing sideways or even fall over. The second end of the connecting mechanism 4 is radially movably connected to the power-generating blade 202. When the power-generating blade 202 rotates around the axis of the installation shaft 101 under the action of wind force, the second end of the connecting mechanism 4 is affected by centrifugal inertia and is thrown to the far end of the power-generating blade 202 away from the installation shaft 101. Accordingly, the first end of the connecting mechanism 4 can drive the photovoltaic panel 3 to rotate to the second position to reduce the wind-receiving area of ​​the device and avoid overturning under the action of wind force. When the wind force changes from large to small, the second end of the connecting mechanism 4 moves to the near end of the power-generating blade 202 close to the installation shaft 101 under the action of the reset mechanism 5. Accordingly, the first end of the connecting mechanism 4 drives the photovoltaic panel 3 to rotate to the first position, so that the photovoltaic panel 3 can be tilted and arranged at the top of the installation frame 1, which is more conducive to receiving light and improving the efficiency of photovoltaic power generation.

[0042] like Figures 1 to 9 As shown, in some embodiments, the connecting mechanism 4 includes a first connecting rod 401, a second connecting rod 402, and a first slip ring 403 and a second slip ring 404 which are sleeved on the mounting shaft 101 and can slide and rotate axially on the mounting shaft 101; the first slip ring 403 and the second slip ring 404 are slidably connected along the circumferential direction of the mounting shaft 101, the first end of the first connecting rod 401 is movably connected to the power generation fan blade 202, the second end of the first connecting rod 401 is rotatably connected to the first slip ring 403, the first end of the second connecting rod 402 is rotatably connected to the photovoltaic panel 3, and the second section of the second connecting rod is rotatably connected to the second slip ring.

[0043] Specifically, when the power generating blade 202 of the wind power rotating mechanism 2 rotates around the installation shaft 101, the first end of the first connecting rod 401 connected to the power generating blade 202 performs centrifugal motion relative to the installation shaft 101, radially away from the installation shaft 101, and the second end of the first connecting rod 401 drives the first slip ring 403 to slide downward along the axis of the installation shaft 101, and the second slip ring 404 slidably connected to the first slip ring 403 also slides downward along the axis of the installation shaft 101 under the drive of the first slip ring 403, so that the second connecting rod 402 can pull the second side of the photovoltaic panel 3 to rotate downward to approach the second position. Among them, the first end of the second connecting rod 402 is hingedly connected to the hinge seat 304 located on the second side of the photovoltaic panel 3, and the second slip ring 404 is restricted by the second connecting rod 402 and can only move in a axial direction of the installation shaft 101, and cannot rotate around the axis.

[0044] It can be seen that when the first end of the first connecting rod 401 moves radially outward along the installation axis 101 due to centrifugal motion or moves radially inward along the installation axis 101 due to the influence of the reset mechanism 5, the second end of the second connecting rod 402 can drive the photovoltaic panel 3 to rotate toward the second position or toward the first position to reduce the wind-exposed area when appropriate or to more conveniently receive solar energy.

[0045] like Figure 8 As shown, in some embodiments, the first slip ring 403 includes a lower sliding plate 405 and an upper sliding plate 406 which are sleeved on the mounting shaft 101 and a connecting plate 407 connecting the lower sliding plate 405 and the upper sliding plate 406, and the second slip ring 404 is slidably clamped between the lower sliding plate 405 and the upper sliding plate 406 along the circumference of the mounting shaft 101, so that the first slip ring 403 can drive the second slip ring 404 to slide axially along the mounting shaft 101.

[0046] Specifically, the first end of the first connecting rod 401 is hingedly connected to the outer periphery of the lower sliding plate 405, and the upper sliding plate 406 is fixedly connected to the lower sliding plate 405 by a cylindrical connecting plate 407 movably sleeved on the outer periphery of the mounting shaft 101, so as to move together with the lower sliding plate 405, and the second slip ring 404 can be circumferentially slidably clamped between the lower sliding plate 405 and the upper sliding plate 406. When the first slip ring 403 moves axially upward along the mounting shaft 101, the second slip ring 404 moves upward under the push of the lower sliding plate 405, and when the first slip ring 403 moves axially downward along the mounting shaft 101, the second slip ring 404 moves downward under the push of the upper sliding plate 406. At the same time, the contact surfaces of the lower sliding plate 405 and the upper sliding plate 406 with the second slip ring 404 are in circumferential sliding contact, so the circumferential sliding of the lower sliding plate 405 and the upper sliding plate 406 along the mounting shaft 101 will not be transmitted to the second slip ring 404, avoiding torsional damage at the connection between the second slip ring 404, the second connecting rod 402 and the photovoltaic panel 3.

[0047] like Figure 6 and Fig. 9 As shown, in some embodiments, a sliding groove 204 perpendicular to the axial direction of the installation axis 101 is provided on the power generation fan blade 202, the first end of the first connecting rod 401 is connected to a centrifugal block 408 slidably set in the sliding groove 204, and the reset mechanism 5 includes a reset spring 501, the first end of the reset spring 501 is connected to the centrifugal block 408, and the second end of the reset spring 501 is connected to the end of the sliding groove 204 away from the installation axis 101.

[0048] Specifically, when the return spring 501 is in a relaxed state, the centrifugal block 408 slides to one end of the sliding groove 204 close to the mounting shaft 101. When the power generation blade 202 is rotated by the wind, the centrifugal block 408 connected to the first end of the first connecting rod 401 slides outward along the sliding groove 204 under the influence of centrifugal inertia, and the compressed return spring 501 provides centripetal force for the centrifugal block 408. When the speed of the power generation blade 202 remains constant and the return spring 501 is compressed to an appropriate stroke, the elastic force of the return spring 501 can just provide centripetal force for the centrifugal block 408. At this time, the centrifugal block 408 remains stationary in the sliding groove 204, and the photovoltaic panel 3 stops rotating. As the wind force changes, the speed of the power generation blade 202 changes accordingly, and the balance between the elastic force provided by the return spring 501 and the centripetal force required for the circular motion of the centrifugal block 408 is broken. The centrifugal block 408 slides inward or outward along the sliding groove 204 again to find a new balance point, and at the same time drives the photovoltaic panel 3 to rotate to adapt to different wind force sizes. It can be seen that when the wind force becomes stronger, the centrifugal block 408 slides outward, driving the photovoltaic panel 3 to the second position to reduce the wind receiving area, and when the wind force becomes weaker, the centrifugal block 408 slides inward under the elastic force of the return spring 501, driving the photovoltaic panel 3 to the first position for easy light reception. It can be seen that the cooperation of the centrifugal block 408 and the return spring 501 in the sliding groove 204 can make the photovoltaic panel 3 rotate accordingly with the wind speed to switch to a suitable tilt angle.

[0049] like Figure 2 and Figure 3 As shown, in some embodiments, a generator motor 6 is fixed on the installation shaft 101 , an input shaft 601 parallel to the installation shaft 101 is provided on the generator motor 6 , and a transmission belt 602 capable of driving the input shaft 601 to rotate is provided on the steering sleeve 201 .

[0050] Specifically, a fixing seat 107 is fixedly connected to the mounting shaft 101, and the generator motor 6 is arranged on the fixing seat 107, which is located on one side of the mounting shaft 101. The input shaft 601 of the generator motor 6 is parallel to the mounting shaft 101, and the end of the input shaft 601 away from the generator motor 6 is connected to the steering sleeve 201 through a transmission belt 602. When the wind power rotation mechanism 2 rotates around the mounting shaft 101 under the action of wind force, the steering sleeve 201 drives the input shaft 601 through the transmission belt 602 so that it can rotate around its own axis, so as to drive the generator motor 6 to generate electricity.

[0051] like Figure 7 As shown, in some embodiments, a rotating base 102 is fixed to the outer periphery of the installation shaft 101 , and one end of the steering sleeve 201 is rotatably placed on the rotating base 102 via a plurality of balls 203 distributed around the axis of the installation shaft 101 .

[0052] Specifically, the end of the steering sleeve 201 facing the rotating base 102 is provided with a groove for accommodating a plurality of balls 203. When the steering sleeve 201 rotates around the axis of the mounting shaft 101, the balls 203 located at the bottom thereof are slidably arranged on the first side of the rotating base 102. The arrangement of the balls 203 effectively reduces the friction between the steering sleeve 201 and the rotating base 102, thereby avoiding energy loss. At the same time, the transmission belt 602 is arranged on the second side of the rotating base 102 facing away from the steering sleeve 201. The steering sleeve 201 and the transmission belt 602 are effectively isolated by the rotating base 102, thereby avoiding friction and collision between the two, thereby avoiding damage to the equipment.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments, a disc 103 perpendicular to the axis of the mounting shaft 101 is fixed thereon, the rotating base 102 is fixedly connected to one side of the disc 103, the generator motor 6 is installed on the other side of the disc 103, and the input shaft 601 can rotatably pass through the disc 103 to connect to a transmission belt 602 located on one side of the disc 103.

[0054] Specifically, the disc 103 is fixed below the wind power rotating mechanism 2, and is used to receive the wind power rotating mechanism 2 and isolate it from the generator motor 6 to avoid mutual interference between the two. The position of the fixing seat 107 on the mounting shaft 101 is also located below the disc 103. In addition, a hole is provided on the disc 103, so that the input shaft 601 of the generator motor 6 can be connected to the transmission belt 602 located above the disc 103 through the hole to drive the generator motor 6 to generate electricity.

[0055] like Figure 1 As shown, in some embodiments, the wind power photovoltaic combined power generation device includes a plurality of photovoltaic panels 3 , and the plurality of photovoltaic panels 3 are distributed on the top of the installation frame 1 around the axis of the installation axis 101 .

[0056] Specifically, a plurality of connecting rods 108 are evenly distributed around the axis of the installation shaft 101 on the support ring 106 located at the top of the installation frame 1, and each connecting rod 108 is hingedly connected to a photovoltaic panel 3 at the end away from the support ring 106. The plurality of photovoltaic panels 3 are evenly distributed around the axis of the installation shaft 101, and the number of photovoltaic panels 3 is the same as the number of power generation blades 202 in the wind-driven rotating mechanism 2 and the horizontal projection position corresponds. The connecting mechanism 4 has a plurality of groups of first connecting rods 401 and second connecting rods 402, and each group of first connecting rods 401 and second connecting rods 402 connects a corresponding group of power generation blades 202 and photovoltaic panels 3. When the wind-driven rotating mechanism 2 rotates under the influence of wind force, the centrifugal blocks 408 on the plurality of power generation blades 202 maintain the same or similar interval with the installation shaft 101, so that the plurality of photovoltaic panels 3 maintain the same or similar angle with the installation shaft 101, and the device is subjected to balanced forces in all directions to avoid overturning.

[0057] like Figure 2 and Figure 5 As shown, in some embodiments, a plurality of connecting rods 108 distributed around the axis of the installation shaft 101 are provided on the top of the installation frame 1 , and each photovoltaic panel 3 is rotatably connected to a connecting rod 108 .

[0058] Specifically, a first side of the photovoltaic panel 3 is provided with a shock-absorbing groove 302 and a sliding block 301 capable of sliding in the shock-absorbing groove 302, wherein the shock-absorbing groove 302 is in contact with the back side of the photovoltaic panel 3 and is located in the rotation plane of the photovoltaic panel 3, and a shock-absorbing spring 303 is connected to the end of the shock-absorbing groove 302, and the other end of the shock-absorbing spring 303 is connected to the sliding block 301. When the second side of the photovoltaic panel 3 rotates around the end of the connecting rod 108 under the pull of the connecting mechanism 4, the sliding block 301 and the shock-absorbing spring 303 cooperate with each other in the shock-absorbing groove 302 to reduce the impact on the photovoltaic panel 3 during the rotation process, and avoid vibration damage to the photovoltaic panel 3 during repeated changes in wind force.

[0059] like Figure 1 , Figure 2 and Fig. 9 As shown, in some embodiments, the wind power and photovoltaic combined power generation device also includes a cleaning mechanism 7, which includes a cleaning strip 701 that can slide along the circumference of the installation axis 101 and fit the light-receiving surfaces of multiple photovoltaic panels 3; wherein the wind-driven rotation mechanism 2 is connected to the cleaning mechanism 7 and can drive the cleaning strip 701 to slide along the circumference of the installation axis 101.

[0060] Specifically, the cleaning mechanism 7 is arranged at the top of the installation shaft 101. When the wind-driven rotating mechanism 2 rotates around the installation shaft 101 under the action of wind force, the cleaning bar 701 of the cleaning mechanism 7 is driven to rotate around the installation shaft 101 to wipe the light-receiving surfaces of the plurality of photovoltaic panels 3 in turn. The cleaning bar 701 itself has a certain degree of compressibility and can be a cleaning cotton cloth or a cleaning sponge. When the cleaning bar 701 does not rotate around the installation shaft 101, the cleaning bar 701 can be compressed and attached to the light-receiving surface of the photovoltaic panel 3. When the cleaning bar 701 rotates around the installation shaft 101, the photovoltaic panel 3 turns to the second position, the cleaning bar 701 is released from compression, the volume is expanded, and it can continue to contact the light-receiving surface of the photovoltaic panel 3 during the rotation process to complete the cleaning of the photovoltaic panel 3.

[0061] In some embodiments, the cleaning mechanism 7 includes a cleaning link 703 for connecting the wind-driven rotating mechanism 2 and the cleaning strip 701. One end of the cleaning link 703 is connected to the steering sleeve 201 of the wind-driven rotating mechanism 2, and the other end is connected to the cleaning strip 701 that can rotate to fit the light-receiving surface of the photovoltaic panel 3. When the wind-driven rotating mechanism 2 rotates under the action of wind, the steering sleeve 201 drives the cleaning link 703 to rotate around the mounting shaft 101, so that the cleaning strip 701 can slide along the circumference of the mounting shaft 101 to wipe the light-receiving surface of the photovoltaic panel 3.

[0062] In some embodiments, the cleaning mechanism 7 includes a cleaning base 702 disposed at the top of the mounting shaft 101 and fixedly connected to the steering sleeve 201, the steering sleeve 201 extends to the top of the mounting shaft 101 to connect to the cleaning base 702, and one end of the cleaning connecting rod 703 is fixedly connected to the cleaning base 702 to receive rotation from the steering sleeve 201.

[0063] like Figure 2 As shown, in some embodiments, the first slip ring 403 is slidably arranged on the outer periphery of the steering sleeve 201, and the steering sleeve 201 is provided with a reduced diameter section along the axial direction of the mounting shaft 101 for limiting the axial displacement of the first slip ring 403. By determining the positions of the two ends of the reduced diameter section of the steering sleeve 201 in the axial direction of the mounting shaft 101, the first position and the second position to which the photovoltaic panel 3 can be rotated can be correspondingly determined, thereby avoiding unnecessary turning of the photovoltaic panel 3.

[0064] like Fig. 9 As shown, in some embodiments, the end of the cleaning link 703 away from the cleaning base 702 is hingedly connected to a rotating rod 704, the other end of the rotating rod 704 is connected to a cleaning bar 701, and the middle part of the cleaning link 703 is hingedly connected to a pulling rod 705. At the same time, the rotating rod 704 and the pulling rod 705 are rotatably connected to each other to form a cross, and a pulling spring 706 is also provided between the rotating rod 704 and the pulling rod 705. When the wind force is small, the light-receiving surface of the photovoltaic panel 3 is prone to accumulate more dust. When it is close to the first position, the light-receiving surface of the photovoltaic panel 3 can squeeze the cleaning bar 701 so that the pulling spring 706 located between the rotating rod 704 and the pulling rod 705 is in a stressed state, and the elastic force of the pulling spring 706 acts on the rotating rod 704 and the pulling rod 705 to generate a tendency of mutual rotation between the two, and as the photovoltaic panel 3 turns to the first position, the greater the degree of squeezing between the cleaning bar 701 and its light-receiving surface, it is beneficial to wipe the light-receiving surface of the photovoltaic panel 3. When the wind is strong, dust is not easily accumulated on the light-receiving surface of the photovoltaic panel 3, and it is relatively close to the second position. The light-receiving surface of the photovoltaic panel 3 gradually moves away from the cleaning strip 701. As the photovoltaic panel 3 gets closer to the second position, the friction between the cleaning strip 701 and the light-receiving surface of the photovoltaic panel 3 becomes smaller, which is beneficial to reducing the kinetic energy loss of the steering sleeve 201 that drives the cleaning strip 701 to rotate during the rotation process, thereby further improving the power generation efficiency of the generator motor 6.
