It should also be understood that terms defined in general dictionaries should be interpreted to have meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or excessively formalized sense, unless otherwise defined herein.

[0035] Techniques, methods and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods and devices should be considered as part of the specification.

[0036] As Figures 1 to 9As shown, the present disclosure provides a self-cleaning wind and photovoltaic combined power generation device, comprising: a mounting frame 1, the mounting frame 1 is provided with a mounting shaft 101; a wind rotating mechanism 2, the wind rotating mechanism 2 is rotatably arranged on the mounting shaft 101 and can rotate around the axis of the mounting shaft 101 under the action of wind force; a photovoltaic panel 3, the photovoltaic panel 3 is connected to the top of the mounting frame 1 and can rotate between a first position at an acute angle with the axis of the mounting shaft 101 and a second position at a right angle with the axis of the mounting shaft 101; a connecting mechanism 4, the first end of the connecting mechanism 4 is connected to the photovoltaic panel 3, the second end of the connecting mechanism 4 is radially movably connected to the wind rotating mechanism 2, and the second end of the connecting mechanism 4 can make centrifugal motion relative to the mounting shaft 101 when the wind 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, the reset mechanism 5 is installed on the wind 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 stops.

[0037] Specifically, the photovoltaic panel 3 is rotatably connected to the top of the mounting frame 1, and the mounting shaft 101 is usually vertically placed after the device is put into use. In the case of small wind force, the rotating speed of the wind rotating mechanism 2 around the axis of the mounting shaft 101 under the action of wind force is small, the radial displacement of the second end of the connecting mechanism 4 relative to the mounting shaft 101 that can be generated in the centrifugal motion is also small, and correspondingly, the first end of the connecting mechanism 4 can only pull the photovoltaic panel 3 to rotate a small angle, the photovoltaic panel 3 is closer to the first position at an acute angle with the vertical direction (i.e. the axis direction of the mounting shaft 101), at this time, the photovoltaic panel 3 is inclinedly arranged on the top of the mounting frame 1, which is conducive to receiving sunlight; in the case of large wind force, the rotating speed of the wind rotating mechanism 2 around the axis of the mounting shaft 101 under the action of wind force is large, the radial displacement of the second end of the connecting mechanism 4 relative to the mounting shaft 101 that can be generated in the centrifugal motion is also large, and 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 with the vertical direction, i.e. the photovoltaic panel 3 tends to lay flat, which effectively reduces the wind area of the photovoltaic panel 3 and avoids the phenomenon that the device is overturned 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, and correspondingly, the first end of the connecting mechanism 4 drives the photovoltaic panel 3 to rotate towards the first position, so that the photovoltaic panel 3 maintains a certain angle with the vertical direction when there is no wind or the wind force is small, so that the photovoltaic panel 3 can be inclinedly arranged on the top of the mounting frame 1, which is conducive to receiving light and improves the power generation efficiency.

[0038] In actual use, it is found that the wind force is the largest at noon due to the influence of the convection of hot and cold air caused by the direct sunlight at noon. At this time, the wind rotating mechanism 2 in the device rotates at a relatively fast speed, which can drive the second end of the connecting mechanism 4 to produce a relatively large radial displacement relative to the installation shaft 101 in the centrifugal motion, and correspondingly make the photovoltaic panel 3 closer to the second position perpendicular to the vertical direction, which not only avoids the device from being overturned due to the wind force, but also is more conducive to the photovoltaic panel 3 to receive the direct sunlight at noon, thereby improving the power generation efficiency of the photovoltaic panel 3 at noon. While in other time periods when the wind force is relatively small, the sunlight is inclined to shine, at this time, the wind rotating mechanism 2 in the device rotates at a relatively slow speed, so that the photovoltaic panel 3 can be inclined to be arranged on the top of the installation frame 1, which is conducive to receiving the inclined sunlight.

[0039] In some embodiments, the installation frame 1 includes a base 104 for placing the installation shaft 101, and a plurality of support columns 105 are arranged on the base 104 and surround and are parallel to the installation shaft 101. The top end of the support column 105 is provided with a support ring 106, and the photovoltaic panel 3 is connected to a connecting rod 108 arranged on the support ring 106. 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 opposite to the first side of the photovoltaic panel 3 is hinged to the first end of the connecting mechanism 4. 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 conducive to light receiving. When the first end of the connecting mechanism 4 pulls the second side of the photovoltaic panel 3 to make it rotate downward, the photovoltaic panel 3 tends to be prostrate 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 rotating mechanism 2 located below the support ring 106 can indirectly drive the photovoltaic panel 3 to rotate through the connecting mechanism 4.

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

[0041] Specifically, the wind rotating mechanism 2 is uniformly distributed along the circumference of the mounting shaft 101, avoiding the generation of unbalanced torque during the rotation of the wind rotating mechanism 2, causing the lateral swing of the mounting frame 1 or even the overturning. The second end of the connecting mechanism 4 is radially movable and connected to the power generation fan blade 202. When the power generation fan blade 202 rotates around the axis of the mounting 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 generation fan blade 202 away from the mounting shaft 101. Correspondingly, the first end of the connecting mechanism 4 can drive the photovoltaic panel 3 to rotate to the second position to reduce the wind area of the device and avoid overturning under the action of wind force. When the wind force decreases, the second end of the connecting mechanism 4 moves to the near end of the power generation fan blade 202 close to the mounting shaft 101 under the action of the reset mechanism 5. Correspondingly, 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 inclined and arranged on the top of the mounting frame 1, which is more conducive to receiving light and improves the photovoltaic power generation efficiency.

[0042] As shown in Figures 1 to 9 In some embodiments, the connecting mechanism 4 includes a first connecting rod 401, a second connecting rod 402, and a first sliding ring 403 and a second sliding ring 404 sleeved on the mounting shaft 101 and capable of sliding and rotating along the axis of the mounting shaft 101; the first sliding ring 403 and the second sliding ring 404 are slidably connected along the circumference 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 sliding ring 403, the first end of the second connecting rod 402 is rotatably connected to the photovoltaic panel 3, and the second end of the second connecting rod is rotatably connected to the second sliding ring.

[0043] Specifically, when the power generation fan blade 202 of the wind rotating mechanism 2 rotates around the mounting shaft 101, the first end of the first connecting rod 401 connected to the power generation fan blade 202 moves away from the mounting shaft 101 along the radial direction, and the second end of the first connecting rod 401 drives the first sliding ring 403 to slide along the axis of the mounting shaft 101, and the second sliding ring 404 connected to the first sliding ring 403 also slides along the axis of the mounting shaft 101 under the drive of the first sliding 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. The first end of the second connecting rod 402 is hingedly connected to the hinge seat 304 on the second side of the photovoltaic panel 3, and the second sliding ring 404 is limited by the second connecting rod 402 and can only move along the axis of the mounting shaft 101, and cannot rotate around the shaft.

[0044] It can be seen that when the first end of the first connecting rod 401 moves radially outward along the installation shaft 101 due to centrifugal motion or moves radially inward along the installation shaft 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, so as to reduce the wind-exposed area when appropriate or 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. 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 that is movably sleeved on the outer periphery of the mounting shaft 101, so as to move together with the lower sliding plate 405. 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. 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 Figure 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 reset spring 501 is in a relaxed state, the centrifugal block 408 slides to the end of the sliding groove 204 close to the mounting shaft 101. When the power generation fan blade 202 is rotated by wind force, 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 reset spring 501 provides a centripetal force for the centrifugal block 408. When the rotation speed of the power generation fan blade 202 remains constant and the reset spring 501 is compressed to an appropriate stroke, the elastic force of the reset spring 501 can just provide a 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. With the change of wind force, the rotation speed of the power generation fan blade 202 changes, and the balance between the elastic force provided by the reset spring 501 and the centripetal force required by the centrifugal block 408 is broken, and the centrifugal block 408 slides inward or outward along the sliding groove 204 to find a new balance point, while driving the photovoltaic panel 3 to rotate to adapt to different wind force. It can be seen that when the wind force increases, the centrifugal block 408 slides outward, driving the photovoltaic panel 3 to tend to the second position to reduce the wind area, and when the wind force decreases, the centrifugal block 408 slides inward under the elastic force of the reset spring 501, driving the photovoltaic panel 3 to tend to the first position to facilitate light receiving. It can be seen that the cooperation of the centrifugal block 408 and the reset spring 501 in the sliding groove 204 can make the photovoltaic panel 3 rotate corresponding to the wind speed to switch to the appropriate inclination angle.

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

[0050] Specifically, the mounting shaft 101 is fixedly connected with a fixed seat 107, and the power generation motor 6 is arranged on the fixed seat 107 on one side of the mounting shaft 101. The input rotating shaft 601 of the power generation motor 6 is parallel to the mounting shaft 101, and the end of the input rotating shaft 601 away from the power generation motor 6 is in transmission connection with the steering sleeve 201 through the transmission belt 602. When the wind power rotating mechanism 2 rotates around the mounting shaft 101 under the action of wind force, the steering sleeve 201 drives the input rotating shaft 601 to rotate around its axis through the transmission belt 602, so as to drive the power generation motor 6 to generate electricity.

[0051] As shown in Figure 7 in some embodiments, the mounting shaft 101 is fixed with a rotating base 102, and one end of the steering sleeve 201 is rotatably placed in the rotating base 102 through a plurality of rolling balls 203 distributed around the axis of the mounting shaft 101.

[0052] Specifically, the end of the steering sleeve 201 is provided with a groove accommodating a plurality of balls 203, when the steering sleeve 201 rotates around the axis of the mounting shaft 101, the balls 203 at the bottom of the steering sleeve 201 slide 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, avoiding energy loss. At the same time, the transmission belt 602 is arranged on the second side of the rotating base 102 away from the steering sleeve 201, and the rotating base 102 effectively isolates the steering sleeve 201 and the transmission belt 602, avoiding friction and collision between them, causing damage to the equipment.

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

[0054] Specifically, the disc 103 is fixed below the wind-driven mechanism 2, which is used to support the wind-driven mechanism 2 while isolating it from the generator 6, avoiding mutual interference between them. The position of the fixing seat 107 on the mounting shaft 101 is also below the disc 103. In addition, the disc 103 is provided with a hole, which facilitates the input shaft 601 of the generator 6 to pass through the hole to connect the transmission belt 602 above the disc 103, so as to drive the generator 6 to generate electricity.

[0055] As shown in Figure 1 shown, in some embodiments, the self-cleaning wind-solar photovoltaic combined power generation device includes a plurality of photovoltaic panels 3, which are distributed around the axis of the mounting shaft 101 on the top of the mounting frame 1.

[0056] Specifically, a plurality of connecting rods 108 are uniformly distributed around the axis of the mounting shaft 101 on the support ring 106 on the top of the mounting frame 1. Each connecting rod 108 has a photovoltaic panel 3 hinged to the end away from the support ring 106. The plurality of photovoltaic panels 3 are uniformly distributed around the axis of the mounting shaft 101, and the number of photovoltaic panels 3 is the same as the number of power generation blades 202 in the wind-driven mechanism 2 and corresponds to the horizontal projection position. The connecting mechanism 4 has a plurality of first connecting rods 401 and second connecting rods 402, each set of first connecting rods 401 and second connecting rods 402 connects a corresponding set of power generation blades 202 and photovoltaic panels 3. When the wind-driven mechanism 2 is rotated by wind force, the centrifugal blocks 408 on the plurality of power generation blades 202 maintain the same or approximate spacing with the mounting shaft 101, so that the plurality of photovoltaic panels 3 maintain the same or approximate angle with the mounting shaft 101, and the device is balanced in each direction, avoiding overturning.

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

[0058] Specifically, the first side of the photovoltaic panel 3 is provided with a damping groove 302 and a sliding block 301 capable of sliding in the damping groove 302, wherein the damping groove 302 is attached to the back of the photovoltaic panel 3 and located in the rotation plane of the photovoltaic panel 3, the end of the damping groove 302 is connected with a damping spring 303, the other end of the damping spring 303 is connected to the sliding block 301, when the second side of the photovoltaic panel 3 is rotated around the end of the connecting rod 108 under the pulling of the connecting mechanism 4, the sliding block 301 and the damping spring 303 cooperate in the damping groove 302 to reduce the impact on the photovoltaic panel 3 during rotation, avoiding vibration damage to the photovoltaic panel 3 during repeated changes in wind force.

[0059] As shown in Figure 1 , Figure 2 and Figure 9 In some embodiments, the self-cleaning wind and light photovoltaic combined power generation device further comprises a cleaning mechanism 7, the cleaning mechanism 7 comprises a cleaning strip 701 capable of sliding along the circumference of the mounting shaft 101 and attached to the light-receiving surface of the plurality of photovoltaic panels 3; wherein the wind rotating mechanism 2 is connected to the cleaning mechanism 7 and can drive the cleaning strip 701 to slide along the circumference of the mounting shaft 101.

[0060] Specifically, the cleaning mechanism 7 is arranged at the top of the mounting shaft 101, when the wind rotating mechanism 2 is rotated around the mounting shaft 101 under the action of wind force, the cleaning strip 701 of the cleaning mechanism 7 is driven to rotate around the mounting shaft 101 to rotate the light-receiving surface of the plurality of photovoltaic panels 3 in turn. As long as there is wind force in the environment to drive the wind rotating mechanism 2 to rotate, the cleaning strip 701 can wipe the light-receiving surface of the photovoltaic panel 3, effectively preventing dust from accumulating on the light-receiving surface of the photovoltaic panel 3. The cleaning strip 701 itself has a certain compressibility, which can be a cleaning cotton cloth or a cleaning sponge, when the cleaning strip 701 is not rotating around the mounting shaft 101, the cleaning strip 701 can be compressed and attached to the light-receiving surface of the photovoltaic panel 3, when the cleaning strip 701 rotates around the mounting shaft 101, the photovoltaic panel 3 turns to the second position, the cleaning strip 701 is decompressed and expands in volume to continue to attach to the light-receiving surface of the photovoltaic panel 3, which can continue to wipe during rotation to complete the cleaning of the photovoltaic panel 3.

[0061] In some embodiments, the cleaning mechanism 7 comprises a cleaning link 703 connecting the wind 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 rotating mechanism 2, and the other end is connected with the cleaning strip 701 capable of rotating and adhering to the light-receiving surface of the photovoltaic panel 3, when the wind rotating mechanism 2 is rotated by wind force, 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 comprises a cleaning base 702 arranged at the top end of the mounting shaft 101 and fixedly connected with the steering sleeve 201, the steering sleeve 201 extends to the top of the mounting shaft 101 to connect the cleaning base 702, and one end of the cleaning link 703 is fixedly connected to the cleaning base 702 to receive rotation from the steering sleeve 201.

[0063] As shown in Figure 2 In some embodiments, the first sliding ring 403 is slidingly arranged on the outer circumference of the steering sleeve 201, and the steering sleeve 201 is provided with a reduced diameter section in the axial direction of the mounting shaft 101 for limiting the axial displacement of the first sliding 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, so as to avoid unnecessary steering of the photovoltaic panel 3.

[0064] As shown in Figure 9As shown, in some embodiments, the cleaning link 703 is hingedly connected with a rotating rod 704 at the end away from the cleaning base 702, the other end of the rotating rod 704 is connected with the cleaning strip 701, the middle part of the cleaning link 703 is hingedly connected with a pulling rod 705, meanwhile, the rotating rod 704 and the pulling rod 705 are rotatably connected with each other to form an intersection, and the pulling spring 706 is arranged 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 easy to accumulate more dust, which is close to the first position under the action of the reset mechanism 5, and the light-receiving surface of the photovoltaic panel 3 can press the cleaning strip 701 so that the pulling spring 706 between the rotating rod 704 and the pulling rod 705 is in a stressed state, the elastic force of the pulling spring 706 acts on the rotating rod 704 and the pulling rod 705 to make the two have a mutual rotation trend, push the cleaning strip 701 to press the photovoltaic panel 3, and as the photovoltaic panel 3 gradually turns to the first position, the degree of pressing between the cleaning strip 701 and the light-receiving surface thereof is greater, which is conducive to wiping the light-receiving surface of the photovoltaic panel 3. When the wind force is large, the light-receiving surface of the photovoltaic panel 3 is not easy to accumulate dust, which is also relatively close to the second position under the driving of the centrifugal block 408, and the light-receiving surface of the photovoltaic panel 3 gradually moves away from the cleaning strip 701, and as the photovoltaic panel 3 is closer to the second position, the contact friction between the cleaning strip 701 and the light-receiving surface of the photovoltaic panel 3 is smaller, which is conducive to reducing the kinetic energy loss of the turning sleeve 201 in the turning process of driving the cleaning strip 701 to rotate, so as to further improve the power generation efficiency of the power generation motor 6.
