DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] Figures 1 to 9 The structure of a solar lighting device according to an embodiment of the present invention is schematically shown.

[0034] like Figures 1 to 9 As shown, a solar energy device for lighting includes a fixing frame 1, a lighting device 2, a solar panel 3, a cleaning device 4, a transmission mechanism 5, a rotating frame 6 and a rotating device 7.

[0035] The lighting device 2 can be installed on the fixing frame 1, and the lighting device 2 is located below the solar panel 3. Figure 1 In the embodiment, the left end of the rotating frame 6 can be rotatably connected to the fixed frame 1 through a rotating shaft, the solar panel 3 and the transmission mechanism 5 can be installed on the rotating frame 6, and the lower side of the rotating frame 6 can be connected with a rotating device 7. When the rotating frame 6 rotates, the direction of the solar panel 3 can be adjusted, the transmission mechanism 5 is connected to the cleaning device 4, and the cleaning device 4 can move with the transmission mechanism 5 to clean the surface of the solar panel 3. In this embodiment, when the rotating device 7 is started, the rotating device 7 can drive the movement of the rotating frame 6, and the left end of the rotating frame 6 can rotate around the upper end of the fixed frame 1 to adjust the direction of the rotating frame 6. The solar panel 3 is connected to the rotating frame 6, so the direction of the solar panel 3 can also be adjusted accordingly.

[0036] The specific structure of the transmission mechanism 5 is described in detail below: In this embodiment, Figure 3 As shown in (a-e), the transmission mechanism 5 includes a motor, a rotating disk 52 and a translation frame 53. The motor is blocked by the rotating disk 52. Figure 3The motor in (a-e) is not shown. In this embodiment, the motor is connected to the rotating disk 52. For example, the motor can be connected to a reduction gear set and connected to the rotating disk 52 through the reduction gear set. When the motor is started, the motor can drive the rotating disk 52 to rotate. The rotating disk 52 cooperates with the translation frame 53, and the motor always rotates in one direction (for example, the motor always rotates clockwise or counterclockwise). The motor can drive the rotating disk 52 to rotate, and the rotating disk 52 can drive the translation frame 53 to move back and forth. The translation frame 53 is connected to the cleaning device 4, and the translation frame 53 can drive the cleaning device 4 to move back and forth. The cleaning device 4 can clean the dust on the surface of the solar panel 3 during the back and forth movement.

[0037] like Figure 1 As shown, the rotating device 7 in this embodiment includes a cylinder, a support plate 11 is fixedly mounted on the upper end of the fixed frame 1, and the lower end of the cylinder is fixedly mounted on the support plate 11. The output shaft of the cylinder is rotatably connected to the lower end surface of the rotating frame 6. When the cylinder is started, the output shaft of the cylinder can push or pull the rotating frame 6 to rotate, thereby adjusting the direction of the rotating frame 6 and the solar panel 3. Figure 1 In the figure, the lighting device 2 includes a fixing plate 21 and a lighting lamp 22 installed on the fixing plate 21. The lighting lamp 22 is electrically connected to a solar panel 3, and the solar panel 3 provides electrical energy for the lighting lamp 22. Therefore, by using the solar panel 3, even in the absence of an external power supply, electrical energy can be provided to the lighting lamp 22 to illuminate the community.

[0038] like Figure 3 As shown in (a-e), the rotating disk 52 is located behind the translation frame 53. In this embodiment, a plurality of cylindrical rods 521 are provided on the rotating disk 52 along the circumferential direction. The cylindrical rods 521 extend forward. The centers of all the cylindrical rods 521 are located on the same circumference. The diameter of the circumference is smaller than the diameter of the rotating disk 52. Therefore, all the cylindrical rods 521 are located on the rotating disk 52. Figure 3 As shown in (a to e), the translation frame 53 is annular, and two rows of teeth 531 are integrally formed on the inner side of the translation frame 53. A gap is formed between two adjacent teeth 531, and the cylindrical rod 521 extends forward. Therefore, the cylindrical rod 521 can be stuck in the gap. The distance between two adjacent gaps is equal to the length of the arc where the centers of the two adjacent cylindrical rods 521 are located. Figure 3 a is used as an example to illustrate the distance between two adjacent gaps. Figure 3 h1 in a, the length of the arc where the centers of two adjacent cylindrical rods 521 are located is Figure 3 h2 in a, h1=h2.

[0039] by Figure 3 (a-e) are used to illustrate that when the motor is started, the motor can drive the rotating disk 52 to rotate clockwise. Figure 3In a, the cylindrical rod 521 on the far right (upper right corner) matches with the first and second teeth from the right in the upper row of teeth 531. In this case, the rotating disk 52 rotates to the position shown in FIG. Figure 3 b, and the translation frame 53 will move to the right for a distance. At this time, the second cylindrical rod 521 from the right cooperates with the second and third teeth from the right of the upper row of teeth 531. Since the rotating disk 52 will not move horizontally, the translation frame 53 will continue to move to the right during the process of the rotating disk 52 continuously rotating clockwise, until it moves to the position shown in FIG. Figure 3 c, then the rotating disk 52 continues to rotate clockwise until the rotating disk 52 rotates to Figure 3 d, the first cylindrical rod 521 from the left on the rotating disk 52 will cooperate with the first tooth and the second tooth from the left on the lower row of teeth. When the rotating disk 52 continues to rotate clockwise, the translation frame 53 will move a distance to the left until it reaches the position shown in FIG. Figure 3 e, and then, as the rotating disk 52 continues to rotate clockwise, it returns to the state shown in FIG. Figure 3 The state shown in a.

[0040] Therefore, the plurality of cylindrical rods 521 will sequentially drive the translation frame 53 to move back and forth. When the cylindrical rods 521 of the rotating disk 52 cooperate with the upper row of teeth 531, the translation frame 53 moves to the right, and when the cylindrical rods 521 of the rotating disk 52 cooperate with the lower row of teeth 531, the translation frame 53 moves to the left. The translation frame 53 is connected to the cleaning device 4. When the translation frame 53 moves left and right, it will drive the cleaning device 4 to move left and right. When the cleaning device 4 moves left and right, the dust on the solar panel 3 can be cleaned.

[0041] like Figure 3 As shown, the transmission mechanism 5 in this embodiment further includes a positioning wheel 54, which is rotatable. There are multiple positioning wheels 54, and the translation frame 53 can be installed between the multiple positioning wheels 54. Specifically, it can be as follows Figure 3 As shown in a, there are four positioning wheels 54 on the top and four positioning wheels 54 on the bottom. The upper positioning wheels 54 and the lower positioning wheels 54 can position the translation frame 53, as shown in FIG. Figure 2 As shown, the left end of the cleaning device 4 is connected to the lower side of the translation frame 53.

[0042] like Figures 4 to 6 As shown, the cleaning device 4 includes two brush bodies 41 and a device housing 42. The left end of the device housing 42 is connected to the translation frame 53. A seat body 31 can be installed on the solar panel 3. The right end of the seat body 31 is higher than the solar panel 3. The seat body 31 can fix and support the solar panel 3. Figure 5In (a-b), a groove 311 is formed on the right side of the base 31, and the device housing 42 is divided into an upper housing 421 and a lower housing 422. The left end of the upper housing 421 and the left end of the lower housing 422 are fixed together, and the right ends and the middle positions of the upper housing 421 and the lower housing 422 are separated. The right end of the upper housing 421 can be connected to the upper end surface of the base 31 through a track. Therefore, when the device housing 42 moves with the translation frame 53, the right end of the upper housing 421 can move along the upper end surface of the base 31. Figure 4 To hide the top view of the upper shell, Figure 4 In the figure, two brush bodies 41 can be installed in parallel on the lower shell 422, the right end of the brush body 41 extends into the groove 311, the groove 311 is provided with a plurality of protrusions 312 at intervals, the distance between two adjacent protrusions 312 is greater than the width of the two brush bodies 41, and a spring 411 is installed at the left end of the brush body 41, and the left end of the spring 411 can be fixed on the lower shell 422.

[0043] like Figures 4 to 6 As shown, when the translation frame 53 moves, the left end of the upper shell 421 and the left end of the lower shell 422 will move with the translation frame 53. Since the right end of the upper shell 421 is installed on the base 31, the right end of the upper shell 421 can move along the base 31, and the right end of the brush body 41 is located in the groove 311 of the base 31. Of course, the right end of the lower shell 422 does not extend into the groove 311, and the brush body 41 will move along the groove 311. The movement speeds of the lower shell 422 and the upper shell 421 are consistent. When the brush body 41 passes through the convex portion 312, as shown in FIG. Figure 5 As shown in FIG. 2 , the brush body 41 is pushed to the left and the spring 411 is compressed. Therefore, the brush body 41 is displaced perpendicular to the moving direction of the device housing 42. When the end of the brush body 41 in contact with the convex portion 312 is separated, the brush body 41 is pushed to the right into the groove 311 by the spring 411. Figure 5 As shown, the brush body 41 can move forward and backward as well as left and right, so as to better clean the dust on the surface of the solar panel 3 , and the brush body 41 is in contact with the solar panel 3 .

[0044] In this embodiment, if Figure 7 As shown, in the length direction of the lower housing 422 (i.e. Figure 4 The brush body 41 is integrally formed with a slide groove 4221 (in the left and right directions shown in the figure), and a protrusion that cooperates with the slide groove 4221 is formed on the side wall of the brush body 41. The protrusion can be stuck in the slide groove 4221 and move along the slide groove 4221. Therefore, the slide groove 4221 can play a positioning role, so that the brush body 41 can move along the slide groove 4221 when passing through the protrusion 312 and being squeezed by the protrusion 312.

[0045] In addition, bristles are arranged on the lower end surface of the brush body 41 , and the bristles can extend from the lower end surface of the lower shell body. The bristles can brush on the solar panel 3 and clean the solar panel 3 .

[0046] In order to achieve a better cleaning effect, the present invention also includes a cleaning liquid extrusion bag 8 and an extrusion rod 9. One end of the cleaning liquid extrusion bag 8 is connected to the translation frame 53, and the other end is connected to the base body 31, and can move along the base body 31. One end of the extrusion rod 9 is fixed on the solar panel 3, and the other end is fixed on the base body 31. When the cleaning liquid extrusion bag 8 moves to the extrusion rod 9, the extrusion rod 9 will squeeze at least a part of the cleaning liquid extrusion bag 8 so that the cleaning liquid in the cleaning liquid extrusion bag 8 is squeezed out.

[0047] like Fig. 9 As shown, in this embodiment, the lower end surface of the cleaning liquid extrusion bag 8 is integrally formed with a liquid outlet 81, the upper end surface of the cleaning liquid extrusion bag 8 is provided with an air port, and the interior of the cleaning liquid extrusion bag 8 is provided with a self-recovering material. When the cleaning liquid extrusion bag passes under the extrusion rod 9, the cleaning liquid in the cleaning liquid extrusion bag 8 is squeezed out, and the internal space of the cleaning liquid extrusion bag 8 is reduced to a certain extent. The internal space of the cleaning liquid extrusion bag 8 can be restored to its original state through the self-recovering material. In this way, the cleaning liquid extrusion bag 8 can be continuously squeezed by the extrusion rod 9. The self-recovering material is an existing material and will not be described in detail. Of course, in other embodiments, the cleaning liquid extrusion bag 8 itself can also inhale air through the air port to restore the size of the internal space.

[0048] The squeezing rod 9 is bent, the distance between the right end of the squeezing rod 9 and the solar panel 3 is less than the height of the cleaning liquid extrusion bag 8, the distance between the right end of the squeezing rod 9 and the solar panel 3 is greater than the height of the device housing 42, and the distance between the left end of the squeezing rod 9 and the solar panel 3 is greater than the height of the cleaning liquid extrusion bag 8. Therefore, the device housing 42 will not hit the squeezing rod 9 during the movement.

[0049] like Fig.10 As shown, a rainwater sensing module 32 and a control module 33 are installed on the solar panel 3. The rainwater sensing module 32 can sense rainwater and generate corresponding signals and send them to the control module 33. The control module 33 generates corresponding control signals and sends the control signals to the transmission mechanism 5. Therefore, when it rains, the control module 33 can control the transmission mechanism 5 to move and drive the cleaning device 4 to move. The cleaning device 4 cleans the solar panel 3 to achieve a better cleaning effect. In addition, as the rainwater drips, the cleaning liquid squeezed out of the cleaning liquid squeezing bag 8 can be flushed without manual cleaning of the cleaning liquid.

[0050] In the present invention, the lighting device can be electrically connected to the solar panel, and the solar panel provides electrical energy for the lighting device. When dust is deposited on the solar panel during use, the transmission mechanism only needs to be started, and the transmission mechanism can drive the cleaning device to move. The cleaning device can clean the solar panel during movement, thereby achieving the function of automatically cleaning the solar panel and improving the working efficiency of the solar panel. The present invention does not require manual handling of ladders and rags to clean the solar panel, thus saving manpower and material resources.

[0051] In addition, the transmission mechanism of the present invention includes a motor, a rotating disk and a translation frame. Through the special rotating disk and translation frame structure of the present invention, when the motor continues to rotate in one direction, the translation frame can move back and forth and drive the cleaning device to move back and forth. Compared with other transmission mechanisms, the transmission mechanism of the present invention is more stable and has a better transmission effect.

[0052] Furthermore, the cleaning device includes two brush bodies and a device housing. When the transmission mechanism drives the brush bodies to move, the brush bodies themselves will also have a displacement perpendicular to the moving direction of the device housing, and the brush bodies can better clean the dust on the solar panel.

[0053] Finally, the cleaning device of the present invention preferably works on rainy days, and the present invention also includes a cleaning liquid extrusion bag and an extrusion rod. When the cleaning liquid extrusion bag is moving, the extrusion rod can squeeze out the cleaning liquid in the cleaning liquid extrusion bag, so that the brush body can have a better cleaning effect in the process of brushing dust.

[0054] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
