Meanwhile, during the unfolding of the petals, the two adjacent petals move relative to each other, and the cleaning member on the petal cleans the solar panel on the adjacent lower petal, thereby reducing the probability of failure of the petals when they are shrunk or unfolded.

Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic equipment, and in particular to a flower-shaped solar cell panel retracting and extending mechanism. Background Art

[0002] As a clean energy, solar energy is increasingly used in various power systems, among which solar panels are the core components of solar energy utilization. In order to further enhance the functionality and aesthetics of solar panels, some designs make solar panels into retractable flower-shaped structures, so that they can be folded and stored when not in use, and unfolded when in use, which not only saves space but also has a certain decorative effect. In addition to providing clean energy, this type of flower-shaped solar panel is often used as a landscape device to embellish urban space and add an artistic atmosphere.

[0003] However, existing flower-shaped solar panels usually adopt a stacked structure. Although this design simplifies the storage process of the petals, there is a gap between the first and last petals in the axial direction, resulting in a gap between the petals. At the same time, each petal is in a different plane after unfolding, and the gaps between the petals are prone to accumulate dust and other debris. If they are not cleaned for a long time, the photovoltaic conversion efficiency of the solar panel will be affected and the overall energy output will be reduced. In addition, dust accumulation will also affect the operation of the device, making the petals not smoothly retracted and released, and may even cause mechanical jams, increasing the difficulty of maintenance. Summary of the invention

[0036] like Figures 1 to 13As shown, an embodiment of the present invention provides a flower-shaped solar panel retracting and extending mechanism, which includes a fixing frame 110, a rotating frame 120, a mounting tube 130, petals 210 and a driving member.

[0037] The fixing frame 110 can be placed on the ground, and the fixing frame 110 is arranged vertically.

[0038] The rotating frame 120 is rotatably connected to the fixed frame 110 around a first direction. Specifically, the rotating frame 120 is disposed on the upper end of the fixed frame 110 . The first direction is a vertical direction, and the rotating frame 120 can rotate around the vertical direction on the upper end of the fixed frame 110 .

[0039] The mounting tube 130 is rotatably connected to the rotating frame 120, wherein the second direction is a horizontal direction, and under the action of the rotating frame 120, the axis of the mounting tube 130 can face any direction. When the mounting tube 130 is in a vertical state, the lower end of the mounting tube 130 is connected to the rotating frame 120, and the upper end of the mounting tube 130 is provided with a mounting groove with an opening facing upward, and a mounting sleeve 140 is provided in the mounting groove, and the mounting sleeve 140 is coaxially arranged with the mounting tube 130, wherein the outer diameter of the mounting sleeve 140 is smaller than the inner diameter of the mounting tube 130, and a plurality of connecting rings 150 are provided on the mounting sleeve 140, and the plurality of connecting rings 150 are coaxially arranged, and the connecting ring 150 at the bottom of the mounting sleeve 140 is fixedly connected to the mounting sleeve 140, and the remaining connecting rings 150 can rotate and slide on the mounting sleeve 140. Specifically, multiple connecting rings 150 are all sleeved on the outside of the installation sleeve 140, the connecting ring 150 at the bottom always remains fixed, and the remaining connecting rings 150 can rotate coaxially relative to the installation sleeve 140, and the remaining connecting rings 150 can slide along the axis of the installation sleeve 140.

[0040] There are multiple petals 210, each of which is slightly fan-shaped. When the petals 210 are in a horizontal state, the petals 210 have a first surface 211 at the top and a second surface 212 at the bottom. A solar panel 280 is arranged on the first surface 211 of each petal 210, and a cleaning member is arranged on the second surface 212 of each petal 210. When two adjacent petals 210 move relative to each other, the cleaning member can clean the solar panel 280 on the adjacent lower petal 210. For example, the cleaning member is a cleaning brush, which is fixedly mounted on the second surface 212 of the petals 210.

[0041] Furthermore, each petal 210 is connected to a connecting ring 150 via a connecting piece. At night, multiple petals 210 are in an overlapping state, and the solar panels 280 on the petals 210 are in a non-working state. At this time, there is a height difference between two adjacent petals 210. After the transmission of the connecting piece, there is a height difference between two adjacent connecting rings 150. Since the petals 210 are slightly fan-shaped, each petal 210 has a first radial edge 213 and a second radial edge 214. The first radial edge 213 of each petal 210 is provided with a first baffle 220. The first baffle 220 is fixedly connected to the first radial edge 213. A first limiting groove 230 can be formed between the first baffle 220 and the first radial edge 213 of the petal 210, and the opening of the first limiting groove 230 faces upward. A second baffle 240 is provided on the second radial edge 214 of each petal 210, and the second baffle 240 is fixedly connected to the second radial edge 214. The second baffle 240 and the second radial edge 214 of the petal 210 form a second limiting groove 250, and the opening of the second limiting groove 250 faces downward. At dawn, the multiple petals 210 rotate relatively, and the multiple petals 210 change from the overlapping state to the unfolded state, and then the two adjacent petals 210 are in a state of relative rotation. When the two adjacent petals 210 rotate relatively, after the petal 210 at the top rotates a certain angle, the second limiting groove 250 of the upper petal 210 and the first limiting groove 230 of the adjacent lower petal 210 are in the same vertical plane, and at this time, the connecting ring 150 on the upper petal 210 is squeezed, so that the connecting ring 150 connected to the upper petal 210 and the connecting ring 150 connected to the lower petal 210 are close to each other, so that the two adjacent petals 210 can be close to each other and in the same plane.

[0042] The driving member includes a first driving unit and a second driving unit, the first driving unit is used to drive the uppermost connecting ring 150 of the mounting sleeve 140 to rotate on the mounting sleeve 140, and the second driving unit is used to apply a downward extrusion force to the uppermost connecting ring 150 of the mounting sleeve 140. When the plurality of petals 210 are changed from an overlapping state to an unfolded state, the first driving unit and the second driving unit work together, the first driving unit drives the uppermost connecting ring 150 of the mounting sleeve 140 to rotate clockwise on the mounting sleeve 140, and the second driving unit squeezes the uppermost connecting ring 150 of the mounting sleeve 140 downward, and the second limit position of the upper petals 210 is changed to the unfolded state. When the groove 250 and the first limiting groove 230 of the adjacent lower petal 210 are in the same vertical plane, the second baffle 240 on the upper petal 210 enters the first limiting groove 230 on the lower petal 210, and the first baffle 220 on the lower petal 210 enters the second limiting groove 250 on the upper petal 210. Therefore, when unfolding multiple petals 210, it is only necessary to drive the top connecting ring 150 of the mounting sleeve 140 to rotate; at the same time, by setting the first limiting groove 230 and the second limiting groove 250, it is ensured that multiple petals 210 can be rotated to the same plane, thereby reducing the gap between two adjacent petals 210.

[0043] A flower-shaped solar panel retracting and extending mechanism of the present invention comprises a fixing frame 110, a rotating frame 120, a mounting tube 130, petals 210 and a driving member. In the flower-shaped solar panel, by mounting a solar panel 280 on the petals 210, a mounting base is provided for the solar panel 280. At night, a plurality of petals 210 are in an overlapping state, and during the day, a plurality of petals 210 are in an unfolded state, and the plurality of petals 210 can change direction as the sun moves. When the petals 210 change from the overlapping state to the unfolded state, the first driving unit drives the uppermost connecting ring 150 of the mounting sleeve 140 to rotate on the mounting sleeve 140, and the connecting ring 150 drives the uppermost petal 210 to rotate relative to the mounting sleeve 140, by connecting the first baffle plate 220 at the first radial edge 213 of the petal 210, and connecting the second baffle plate 240 at the second radial edge 214 of the petal 210, a first limiting groove 230 is formed at the position of the first radial edge 213 of the petal 210, and a second limiting groove 250 is formed at the position of the second radial edge 214 of the petal 210. During the rotation of the uppermost petal 210 relative to the mounting sleeve 140, the second baffle plate 240 on the uppermost petal 210 moves to the first baffle plate 220 on the adjacent lower petal 210. The position of the limiting groove 230, under the action of the second driving unit squeezing the connecting ring 150 at the top of the mounting sleeve 140 downward, the top petal 210 moves downward, and the second baffle 240 on the top petal 210 moves into the first limiting groove 230 on the adjacent lower petal 210, so that the two adjacent petals 210 are transformed into the same plane. As the connecting ring 150 at the top of the mounting sleeve 140 rotates on the mounting sleeve 140, multiple petals 210 are all in the same plane. At the same time, in the process of unfolding the petals 210, there is relative movement between the two adjacent petals 210, and the cleaning parts on the petals 210 clean the solar panels 280 on the adjacent lower petals 210, thereby reducing the probability of failure of the petals 210 when contracting or unfolding.

[0044] In one embodiment, a flower-shaped solar panel retracting and unfolding mechanism further includes a plurality of reset plates 260. At dawn, the plurality of petals 210 need to be transformed from an overlapping state to an unfolded state, and at dusk, the plurality of petals 210 need to be transformed from an unfolded state to an overlapping state. Each reset plate 260 is fixedly connected to a first baffle 220. When the petals 210 are in a horizontal state, each reset plate 260 is disposed below a first baffle 220. The first baffle 220 can ensure that two adjacent petals 210 no longer move relative to each other after reaching an overlapping state, and the reset plate 260 on one petal 210 can contact the first baffle 220 on the adjacent lower petal 210. During the process of the petals 210 changing from the unfolded state to the overlapping state, the first driving unit drives the connecting ring 150 at the top of the mounting sleeve 140 to rotate counterclockwise on the mounting sleeve 140, and the second driving unit reduces the downward extrusion force of the connecting ring 150 at the top of the mounting sleeve 140. At this time, the connecting ring 150 at the top drives the petals 210 to rotate counterclockwise synchronously, and the second baffle 240 on the top petal 210 gradually separates from the first limiting groove 230 on the adjacent lower petal 210. When the reset plate 260 on the petal 210 contacts the first baffle 220 on the adjacent lower petal 210, the connecting ring 150 at the top rotates synchronously with the adjacent lower connecting ring 150.

[0045] In one embodiment, the side wall of the first radial edge 213 and the side wall of the second radial edge 214 are both configured as inclined surfaces. Specifically, in any petal 210, and when the petal 210 is in a horizontal state, the side walls of the first baffle 220 and the second baffle 240 are both in a vertical state, wherein the lower side wall of the first baffle 220 is flush with the second surface 212 of the petal 210, the upper side wall of the second baffle 240 is flush with the first surface 211 of the petal 210, the width of the first baffle 220 in the vertical direction is smaller than the thickness of the petal 210 in the vertical direction, and the width of the second baffle 240 in the vertical direction is smaller than the thickness of the petal 210 in the vertical direction. The edge 213 and the second radial edge 214 are set as inclined surfaces, so that the first limiting groove 230 is slightly V-shaped with the opening facing upward, and the second limiting groove 250 is slightly V-shaped with the opening facing downward. When the petals 210 are changed from the overlapping state to the unfolded state, it is convenient for the second baffle 240 on the petal 210 of the upper one of the two adjacent petals 210 to move into the first limiting groove 230 of the adjacent lower petal 210, and at the same time, the first baffle 220 on the petal 210 of the lower one of the two adjacent petals 210 moves into the second limiting groove 250 of the adjacent upper petal 210. When the petals 210 are changed from the unfolded state to the overlapping state, according to the shapes of the first limiting groove 230 and the second limiting groove 250, it is convenient for the second baffle 240 on the petal 210 of the upper one of the two adjacent petals 210 to be separated from the first limiting groove 230 of the adjacent lower petal 210, and at the same time, the first baffle 220 on the petal 210 of the lower one of the two adjacent petals 210 is separated from the second limiting groove 250 of the adjacent upper petal 210.

[0046] In one embodiment, the connecting member is a connecting rod 270, the inner diameter of each connecting ring 150 is the same, and the outer diameter of each connecting ring 150 is different. In one embodiment, when the mounting sleeve 140 is in a vertical state, the outer diameters of the plurality of connecting rings 150 decrease from top to bottom along the axis direction of the mounting sleeve 140, and each connecting rod 270 is bent, one end of the connecting rod 270 is fixedly connected to a petal 210, and the other end of the connecting rod 270 is fixedly connected to a connecting ring 150. By setting the outer diameters of the plurality of connecting rings 150, it is prevented that the connecting rods 270 collide with each other when the connecting rings 150 rotate. In one embodiment, the outer diameters of some connecting rings 150 are the same, and the connecting rings 150 with the same outer diameters are symmetrically arranged about the middle of the length direction of the mounting sleeve 140.

[0047] In one embodiment, the first driving unit includes a driving shaft 310, a first driving motor 320 and a transmission member. The driving shaft 310 is coaxially rotatably arranged inside the mounting sleeve 140. The first driving motor 320 is fixedly arranged on the mounting cylinder 130. The first driving motor 320 is used to drive the driving shaft 310 to rotate. The transmission member is arranged between the driving shaft 310 and the uppermost connecting ring 150 of the mounting sleeve 140. When the driving shaft 310 rotates, the connecting ring 150 at the uppermost of the mounting sleeve 140 rotates synchronously. In this embodiment, the transmission member is a transmission sleeve 330. The transmission sleeve 330 is coaxially sleeved on the outer side of the mounting sleeve 140. When the mounting sleeve 140 is in a vertical state, the upper end of the transmission sleeve 330 is connected to the driving shaft 310, and the lower end of the transmission sleeve 330 is connected to the uppermost connecting ring 150 of the mounting sleeve 140. When the driving shaft 310 rotates, the uppermost connecting ring 150 of the mounting sleeve 140 rotates synchronously. Furthermore, the rotation direction of the first driving motor 320 can be switched to ensure that the connecting ring 150 can rotate clockwise and counterclockwise on the mounting sleeve 140 .

[0048] In one embodiment, the second drive unit includes a pressing sleeve 340 and a regulating cylinder 350. The pressing sleeve 340 is coaxially arranged with the mounting cylinder 130. The upper end of the pressing sleeve 340 is rotatably connected with the upper end of the driving shaft 310. The driving shaft 310 can be telescopically arranged. The regulating cylinder 350 is used to adjust the length of the driving shaft 310. The lower end of the pressing sleeve 340 abuts against the connecting ring 150 at the top of the mounting sleeve 140. Specifically, the driving shaft 310 includes a fixed portion 311 and a sliding portion 312. The fixed portion 311 has a sliding cavity inside. The sliding portion 312 is inserted into the sliding cavity. The sliding portion 312 can slide in the sliding cavity. When the sliding portion 312 is inserted into the sliding cavity, the sliding cavity is in a relatively closed state. The regulating cylinder 350 is a cylinder. The regulating cylinder 350 can supply or exhaust air into the sliding cavity, thereby adjusting the overall length of the driving shaft 310. The upper end of the transmission sleeve 330 is slidably connected with the sliding portion 312 of the driving shaft 310. When the drive shaft 310 rotates, the regulating cylinder 350 is used to extract the gas in the sliding cavity, so that the drive shaft 310 has a tendency to shorten, and the drive shaft 310 can drive the extrusion sleeve 340 to squeeze downward the uppermost connecting ring 150 of the mounting sleeve 140. In other embodiments, the upper end of the extrusion sleeve 340 is rotatably connected to the upper end of the drive shaft 310, and the lower end of the extrusion sleeve 340 abuts against the first surface 211 of the uppermost petal 210, and the extrusion sleeve 340 directly squeezes the petal 210.

[0049] In one embodiment, there is a first preset angle between the plane where the first surface 211 or the second surface 212 of the petal 210 is located and the plane where the connecting ring 150 is located. Specifically, when the extrusion sleeve 340 extrudes the first surface 211 of the petal 210, the size of the first preset angle between the plane where the first surface 211 or the second surface 212 of the petal 210 is located and the plane where the connecting ring 150 is located will change, and the binding force between two adjacent petals 210 will be further increased, preventing the flowing wind from interfering with the state of the multiple petals 210.

[0050] In one embodiment, the cleaning member includes a plurality of cleaning strips 290, and the plurality of cleaning strips 290 are all disposed on the second surface 212 of the petals 210. Cleaning bristles are disposed on the cleaning strips 290. When two adjacent petals 210 move relative to each other, the cleaning strips 290 on the second surface 212 of the petals 210 clean the solar panel 280 on the adjacent lower first surface 211, thereby improving the cleanliness of the surface of the solar panel 280 and thereby ensuring that the solar panel 280 can work efficiently.
