Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel cleaning technology, and in particular to a photovoltaic panel cleaning device. Background Technology

[0002] Currently, the methods used to clean photovoltaic panels are broadly divided into manual cleaning and automatic cleaning. Manual cleaning is less efficient than automatic cleaning, and cleaning high-altitude photovoltaic panels on rooftops is dangerous. Automatic cleaning devices can significantly improve cleaning efficiency and power generation efficiency. Automatic cleaning devices generally include a drive mechanism, a walking mechanism, a transmission mechanism, and guide rails. The cost of automatic cleaning devices constrains the development of photovoltaic panel cleaning. The transmission method, guide rail material structure, and drive mechanism are key aspects of cost reduction. However, during the cleaning process, leaves, dust, and other impurities can easily scratch the photovoltaic panels between them and the cleaning device. Summary of the Invention

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1 This is the first embodiment of the present invention, characterized in that the cleaning component 200 is driven to rotate by the driving unit 100, and the cleaning of the photovoltaic panel is completed by the combination of movement and rotation on the surface of the photovoltaic panel.

[0032] Specifically, the drive unit 100 includes a drive motor 101, a reversing rod 102, a transmission belt 103, and a linkage assembly 104. The reversing rod 102 is located on the side of the drive motor 101, and the transmission belt 103 is located on the other side of the reversing rod 102 and the drive motor 101. The linkage assembly 104 is linked with the transmission belt 103. The cleaning assembly 200 includes a drive shaft 201, a cleaning roller 202, and a photovoltaic panel 203. The cleaning roller 202 and the drive shaft 201 are coaxially coupled, and the photovoltaic panel 203 is slidably coupled with the cleaning roller 202.

[0033] Furthermore, the drive motor 101 is linked with the reversing rod 102 through the reversing structure, so that the transmission belts 103 linked on both sides of the drive motor 101 rotate in opposite directions. The linkage component 104 provides a tension to support the transmission belts 103, so that they always remain linked.

[0034] Furthermore, the drive shaft 201 is engaged with the pulley and internally coupled with the cleaning roller 202 via a key connection, enabling the cleaning roller 202 to rotate on the photovoltaic panel 203. The toothed structure on the side of the drive shaft 201 engages with the groove on the photovoltaic panel 203, allowing the entire cleaning roller 202 to complete a rotational and translational motion.

[0035] In summary, by driving the transmission shaft to rotate via a drive motor, the cleaning roller rotates and moves back and forth along the surface of the photovoltaic panel during rotation. At the same time, the direction of rotation of the cleaning roller is opposite to the direction of movement, which can greatly improve the cleaning effect.

[0036] Example 2

[0037] Reference Figures 1-3The second embodiment of the present invention, based on the first embodiment, further includes a drive motor 101, including a first half-shaft 101a and a second half-shaft 101b. The first half-shaft 101a and the second half-shaft 101b are respectively disposed on both sides of the drive motor 101. The first half-shaft 101a includes a first gear 101a-1 disposed at its end, and the second half-shaft 101b includes a first pulley 101b-1 disposed at its end.

[0038] Furthermore, the reversing lever 102 includes a reversing gear 102a, a reversing pulley 102b, a reversing shaft 102c, and a support plate 102d. The reversing shaft 102c includes a reversing gear 102c-1 disposed on its top. The reversing gear 102a is disposed on the side of the reversing lever 102, the reversing pulley 102b is disposed on the other side of the reversing lever 102, the reversing shaft 102c is disposed on the side of the reversing gear 102a, and the support plate 102d is disposed in the middle of the reversing lever 102.

[0039] Preferably, the linkage assembly 104 includes a mating rod 104a disposed at its end, a mating pulley 104a-1 disposed at the end of the mating rod 104a, and the other side of the mating rod 104a slidingly engaging with the linkage assembly 104. The linkage assembly 104 also includes a fixing block 104b disposed at its end, a spring 104b-1 disposed at the end of the fixing block 104b, and the other end of the spring 104b-1 fixedly connected to the mating rod 104a. The mating rod 104a moves up and down along the slide of the linkage assembly 104.

[0040] In the previous embodiment, the drive motor 101 is linked with the reversing rod 102 through the reversing structure, so that the transmission belts 103 linked on both sides of the drive motor 101 rotate in opposite directions. The linkage component 104 provides a tension to support the transmission belts 103 so that they always remain linked.

[0041] Furthermore, the drive shaft 201 is engaged with the pulley and internally coupled with the cleaning roller 202 via a key connection, enabling the cleaning roller 202 to rotate on the photovoltaic panel 203. The toothed structure on the side of the drive shaft 201 engages with the groove on the photovoltaic panel 203, allowing the entire cleaning roller 202 to complete a rotational and translational motion.

[0042] Specifically, the drive motor 101 drives the first half-shaft 101a to rotate. The first gear 101a-1 at the end of the first half-shaft 101a meshes with the reversing gear 102a at the end of the reversing rod 102 through the reversing gear 102c-1 on the reversing shaft 102c, so that the reversing rod 102 rotates in the opposite direction to the first half-shaft 101a, thus causing the transmission belts 103 on both sides to move in different directions.

[0043] Furthermore, the pulley 104a-1, under the action of the spring 104b-1, expands the belt, thereby maintaining the linkage of the transmission belt and driving the cleaning component to complete the cleaning work.

[0044] Example 3

[0045] Reference Figures 1-8 The third embodiment of the present invention is based on the first two embodiments: the transmission shaft 201 includes a rotating tooth 201a disposed at its end, a moving tooth 201b disposed on the side of the rotating tooth 201a, and a first connecting shaft 201c and a second connecting shaft 201d disposed in the middle, the two connecting shafts being movably engaged.

[0046] Furthermore, a first rotary spline 201c-1 is provided on the side of the first connecting shaft 201c, a connecting end face 201c-2 is provided on the side of the first rotary spline 201c-1, a connector head 201c-21 is provided at the end of the connecting end face 201c-2, a second rotary spline 201d-1 is provided at the end of the second connecting sleeve 201d, a coupling sleeve 201d-2 is provided at the end of the second rotary spline 201d-1, and a coupling hole 201d-21 is provided at the end of the coupling sleeve 201d-2.

[0047] Preferably, the cleaning roller 202 has an actuating cavity 202a and a power cavity 202b inside. The actuating cavity 202a is smoothly disposed. The power cavity 202b has limiting grooves 202b-1 on both sides to cooperate with the first rotary spline 201c-1 and the second rotary spline 201d-1, respectively. The photovoltaic panel 203 has a first stop block 203a, a second stop block 203b and a toothed groove 203c on its side. The toothed groove 203c has a first moving toothed belt 203c-1 and a second moving toothed belt 203c-2, and the two toothed belts are respectively distributed on both sides of different planes of the toothed groove 203c.

[0048] In the first two embodiments, the drive unit 100 includes a drive motor 101, a reversing rod 102, a transmission belt 103, and a linkage assembly 104. The reversing rod 102 is disposed on the side of the drive motor 101, and the transmission belt 103 is disposed on the other side of the reversing rod 102 and the drive motor 101. The linkage assembly 104 is linked and cooperates with the transmission belt 103. The cleaning assembly 200 includes a drive shaft 201, a cleaning roller 202, and a photovoltaic panel 203. The cleaning roller 202 and the drive shaft 201 are coaxially coupled, and the photovoltaic panel 203 is slidably coupled with the cleaning roller 202.

[0049] Furthermore, the drive motor 101 is linked with the reversing rod 102 through the reversing structure, so that the transmission belts 103 linked on both sides of the drive motor 101 rotate in opposite directions. The linkage component 104 provides a tension to support the transmission belts 103, so that they always remain linked.

[0050] Furthermore, the drive shaft 201 is engaged with the pulley and internally coupled with the cleaning roller 202 via a key connection, enabling the cleaning roller 202 to rotate on the photovoltaic panel 203. The toothed structure on the side of the drive shaft 201 engages with the groove on the photovoltaic panel 203, allowing the entire cleaning roller 202 to complete a rotational and translational motion.

[0051] Preferably, the drive motor 101 drives the rotation of the first half-shaft 101a. The first gear 101a-1 at the end of the first half-shaft 101a meshes with the reversing gear 102a at the end of the reversing rod 102 through the reversing gear 102c-1 on the reversing shaft 102c, so that the reversing rod 102 rotates in the opposite direction to the first half-shaft 101a, thus causing the transmission belts 103 on both sides to move in different directions.

[0052] Furthermore, the pulley 104a-1, under the action of the spring 104b-1, expands the belt, thereby maintaining the linkage of the transmission belt and driving the cleaning component to complete the cleaning work.

[0053] In this embodiment, the rotating teeth 201a at the end of the drive shaft 201 are slidably engaged with the pulleys of the drive belt 103. The drive shaft 201 can change the rotation direction of the cleaning roller 202 by sliding inside the cleaning roller 202. At the same time, when it reaches the edge of the photovoltaic panel, it can change the movement direction of the cleaning roller 202 on the photovoltaic panel.

[0054] Specifically, the drive shaft 201 is divided into two parts, namely the first connecting shaft 201c and the second connecting shaft 201d. The first connecting shaft 201c and the second connecting shaft 201d are movable and the rotation of the two ends does not affect each other. The connector 201c-21 and the insertion hole 201d-21 are connected by a sliding fit to ensure that the movement of the two shafts does not affect each other. The internal first rotary spline 201c-1 and second rotary spline 201d-1 are also present.

[0055] Furthermore, the moving teeth 201b mesh with the tooth groove 203c, and the moving teeth 201b on both sides of the drive shaft 201 respectively contact the first moving tooth belt 203c-1 and the second moving tooth belt 203c-2 of the tooth groove 203c. The two moving tooth belts are respectively set on the upper and lower surfaces and are not on the same plane. Therefore, even if the two ends of the drive shaft 201 rotate in different directions, the drive shaft can move along one direction of the photovoltaic panel and drive the cleaning stick 202 to move at the same time.

[0056] Furthermore, the actuating cavity 202b encloses the connection between the two sections of the drive shaft 201, allowing the drive shaft 201 to move axially inside the cleaning stick 202. The power cavity 202b is provided with a limiting groove 202b-1, which, in conjunction with the spline, enables the cleaning stick to obtain power.

[0057] In use, the drive motor 101 is started first. The drive motor drives the transmission belts 103 located on both sides of the photovoltaic panel to rotate through two half shafts. Since the transmission uses a reversing rod 102, the transmission belts 103 on both sides rotate in different directions. Therefore, the transmission shaft 201 that it cooperates with also rotates in different directions at both ends. The moving teeth 201b on both sides mesh with different toothed belts of the toothed groove 203c. One side meshes with the first moving toothed belt 203c-1, and the other side meshes with the second moving toothed belt 203c-2. Since the two toothed belts are distributed in different positions, torque that moves in one direction can be obtained on the shafts at both ends with different rotation directions.

[0058] Furthermore, when the cleaning roller 202 moves from the drive motor side, the second rotating spline 201c-2 engages with the limiting groove 202b-1 on its side. At this time, the cleaning roller 202 and the transmission belt on the reversing rod 102 rotate in different directions, and the cleaning roller 202 moves away from the drive motor 101. At this time, the rotation direction of the cleaning roller 202 is opposite to the tangential direction of movement.

[0059] Furthermore, when the first stop 203a is contacted, the drive shaft 201 is pushed by the stop, at which point the drive shaft 201 moves axially, the meshing of the moving teeth 201b changes, and the first rotating spline 201c-1 meshes with the limiting groove 202b-1 on one side, causing the rotation direction of the cleaning roller 202 to reverse. At the same time, the cleaning roller 202 moves towards the drive motor. When the drive shaft 201 contacts the second stop 203b, it reverses again, and the cycle repeats.

[0060] In summary, by driving the transmission shaft to rotate via a drive motor, the cleaning roller rotates and moves back and forth along the surface of the photovoltaic panel. Furthermore, the direction of rotation of the cleaning roller is opposite to the direction of movement during this motion, which greatly improves the cleaning effect. The ability to change the rotation direction of the cleaning roller during the back-and-forth motion ensures efficient cleaning of the photovoltaic panel and extends its service life.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
