Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, specifically to a photovoltaic module and photovoltaic device integrating an automatic cleaning and monitoring mechanism. Background Technology

[0002] Photovoltaic modules, commonly known as solar panels, are the core power generation unit of a photovoltaic power generation system. They work by utilizing the photovoltaic effect, where sunlight irradiates semiconductor materials, directly converting light energy into direct current (DC).

[0003] In the current technology, photovoltaic modules are all installed outdoors, and their surfaces are prone to dust accumulation. The accumulation of dust will affect the efficiency of photovoltaic modules in converting light energy into electrical energy. Therefore, photovoltaic modules in the current technology need to be cleaned regularly by staff.

[0004] However, the above-mentioned solution of having staff regularly clean the photovoltaic modules has the following drawbacks: 1. The cleaning efficiency is relatively slow; 2. When staff wipe the surface of the photovoltaic modules, some areas may be missed, resulting in poor cleaning efficiency; 3. The demand for manual cleaning personnel is large, and the maintenance cost is too high; 4. Traditional cleaning uses brushes, and brushes with bristles that are too soft will affect the cleaning effect, while brushes with bristles that are too hard will damage the photovoltaic panels. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic module with an integrated automatic cleaning and monitoring mechanism to solve the problem of slow surface cleaning efficiency of photovoltaic modules in the prior art.

The cleaning cotton positioning seat is sleeved on the mounting shaft and is positioned by a limiting nut on the screw. The cleaning cotton layer covers the cleaning cotton positioning seat in a ring.

[0010] Preferably, a secondary connecting seat is integrally formed on the side wall of the primary connecting seat, and a secondary rotating shaft is rotatably mounted on the secondary connecting seat via a secondary ball bearing. A secondary transmission gear and a force-bearing gear are mounted on the secondary rotating shaft, and a secondary driven gear is mounted on the primary rotating shaft. The secondary driven gear meshes with the secondary transmission gear. A force-bearing rack is fixedly mounted on the side wall of the photovoltaic mounting bracket via the primary connecting bracket, and the force-bearing gear and the force-bearing rack are configured to cooperate.

[0011] Preferably, a connecting plate is integrally formed on the inner side wall of the primary connecting seat, and an mounting ring is detachably installed on the connecting plate. A primary snap-fit ​​groove is provided on the side wall of the primary rotating shaft, and a secondary snap-fit ​​groove is provided on the mounting ring. The mounting ring and the primary rotating shaft are connected by a spiral spring, and the inner and outer end interfaces of the spiral spring are respectively snap-fitted into the primary snap-fit ​​groove and the secondary snap-fit ​​groove.

[0012] Preferably, the force-bearing gear is mounted on the secondary rotating shaft via a ratchet-type one-way bearing. When the cleaning module moves from top to bottom along the photovoltaic panel, the force-bearing gear drives the secondary rotating shaft. At this time, the spiral spring is accumulating elastic potential energy. When the cleaning module moves from bottom to top along the photovoltaic panel, the force-bearing gear rotates freely on the secondary rotating shaft.

[0013] Preferably, a vacuum cleaner head is fixedly installed on the lower side of the photovoltaic mounting bracket via a secondary connecting bracket.

[0014] Preferably, a primary dust cover is fixedly installed on the upper mounting base, and a secondary dust cover is provided on the primary dust cover.

[0015] A photovoltaic device integrating an automatic cleaning monitoring mechanism includes a photovoltaic module with an integrated automatic cleaning monitoring mechanism. The photovoltaic device with an integrated automatic cleaning monitoring mechanism also includes a power conversion module, an energy storage module, an angle adjustment module, and a monitoring module. The angle adjustment module is used to adjust the direction angle of the photovoltaic module, and the monitoring module is used to monitor the surface of the photovoltaic panel. The monitoring module is electrically connected to a monitoring system.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. A photovoltaic device with an integrated automatic cleaning and monitoring mechanism, consisting of a photovoltaic mounting bracket, photovoltaic panel, cleaning module, and drive structure, is used. The drive structure is composed of a guide rod, a transmission screw, a moving seat, and a primary connecting seat. A servo motor drives the transmission screw, which in turn moves the moving seat, causing the cleaning module to move up and down along the surface of the photovoltaic panel. This results in automatic cleaning of the photovoltaic panel surface. The cleaning module provides more complete coverage of the photovoltaic panel, thus improving the cleaning effect. Furthermore, the roller-shaped cleaning module offers better rolling cleaning than traditional brushes and provides better protection for the photovoltaic panel compared to brush bristles.

[0017] 2. When the cleaning module is driven by the drive structure, the force-bearing gear moves along the force-bearing rack synchronously, thereby causing the secondary shaft to rotate. The secondary transmission gear drives the secondary driven gear, which in turn drives the primary shaft to rotate. This allows the spiral spring to accumulate elastic potential energy. When the force-bearing gear disengages from the force-bearing rack, the spiral spring releases its elastic potential energy, causing the cleaning module to rotate and shaking off the dust on its surface.

[0018] 3. The suction generated by the operation of the vacuum cleaner main unit creates negative pressure at the vacuum cleaner head, which absorbs the dust thrown off the cleaning module, thus preventing secondary pollution of the photovoltaic panel surface by the dust.

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Example 1 Photovoltaic modules are photovoltaic panels used to convert light energy into electrical energy. However, in current technology, photovoltaic panels are placed outdoors, where there is a lot of dust. As a result, dust can easily adhere to the photovoltaic panels. Since the accumulation of dust can affect the efficiency of the photovoltaic panels in converting light energy into electrical energy, the surface of the photovoltaic panels needs to be cleaned regularly. Traditional cleaning methods use brushes, but brushes with bristles that are too soft will affect the cleaning effect, while brushes with bristles that are too hard will damage the photovoltaic panels.

[0023] It should be emphasized that the core improvement of this embodiment is that the cleaning module 3 is driven by the driving structure 4, so that the cleaning module 3 can automatically clean the surface of the photovoltaic panel 2.

[0024] like Figures 1-7 and Figure 9 In this embodiment, a photovoltaic device integrating an automatic cleaning and monitoring mechanism includes a photovoltaic mounting bracket 1, a photovoltaic panel 2, a cleaning module 3, and a drive structure 4. The photovoltaic panel 2 is fixedly mounted on the photovoltaic mounting bracket 1. The cleaning module 3 is disposed against the upper surface of the photovoltaic panel 2. The drive structure 4 is mounted on the photovoltaic mounting bracket 1 and is used to drive the cleaning module 3 to move up and down along the upper surface of the photovoltaic panel 2. There is one drive structure 4 on each side of the photovoltaic mounting bracket 1, and the drive structure 4 includes a guide rod 15, a transmission screw 16, a moving seat 17, and a primary connecting seat 19. An upper mounting seat 13 and a lower mounting seat 14 are fixedly mounted on the upper and lower sides of both ends of the photovoltaic mounting bracket 1, respectively. The guide rod 15 is fixedly mounted on... Between the upper mounting base 13 and the lower mounting base 14, the transmission screw 16 is rotatably mounted between the upper mounting base 13 and the lower mounting base 14. The movable base 17 is movably mounted on the guide rod 15. The screw hole 18 on the movable base 17 is connected to the transmission screw 16. The primary connecting base 19 is integrally formed with the movable base 17. The two ends of the cleaning module 3 are respectively mounted on the primary connecting bases 19 on both sides. The upper mounting base 13 is fixedly connected to the motor base 39. The motor base 39 is fixedly mounted to the servo motor 40. The output shaft of the servo motor 40 is fixedly mounted to the primary transmission gear 41. The upper end of the transmission screw 16 is fixedly mounted to the primary driven gear 42. The primary driven gear 42 and the primary transmission gear 41 are meshed.

[0025] The working principle of cleaning module 3 and driver structure 4: as follows Figures 1-7 and Figure 9A photovoltaic device with an integrated automatic cleaning and monitoring mechanism is constructed by setting up a photovoltaic mounting bracket 1, a photovoltaic panel 2, a cleaning module 3, and a drive structure 4. The drive structure 4 is configured to consist of a guide rod 15, a transmission screw 16, a moving seat 17, and a primary connecting seat 19. The servo motor 40 drives the transmission screw 16, which in turn moves the moving seat 17, thereby causing the cleaning module 3 to move up and down along the surface of the photovoltaic panel 2. This results in automatic cleaning of the surface of the photovoltaic panel 2. The cleaning module 3 provides more complete coverage of the photovoltaic panel 2, thus improving the cleaning effect. Furthermore, the roller-shaped cleaning module 3 provides better rolling cleaning than traditional cleaning brushes and offers better protection for the photovoltaic panel 2 compared to brush bristles.

[0026] It should be noted that, such as Figure 7 and Figure 9 A transmission sprocket 43 is fixedly installed on the transmission screw 16, and the transmission sprockets 43 on both sides of the transmission screw 16 are connected by a transmission chain 44, which facilitates synchronous driving of the drive structures 4 on both sides by a single drive motor.

[0027] It should be noted that, such as Figure 5 and Figure 6 A locking groove 5 is provided on the outer side wall of the frame of the photovoltaic panel 2. A positioning component 6 is fixedly installed on the upper surface of the photovoltaic mounting bracket 1 by positioning screws. During actual installation, the end of the positioning component 6 is pressed against the lower side of the locking groove 5, and the upper surface of the positioning component 6 is lower than the upper surface of the photovoltaic panel 2, so as to avoid the installation structure of the photovoltaic panel 2 from interfering with the cleaning module 3.

[0028] Example 2 It is understandable that in Embodiment 1, the cleaning module 3 is driven by the driving structure 4 to clean the photovoltaic panel 2. However, during long-term continuous use, the cleaning module 3 itself will also accumulate a lot of dust, which will reduce the cleaning effect of the cleaning module 3 on the photovoltaic panel 2.

[0029] It should be emphasized that the core improvement of this embodiment is that by setting an energy storage structure, the drive structure 4 stores energy when driving the cleaning module 3 to move, and releases energy through the energy storage structure when the cleaning module 3 moves to a position away from the photovoltaic panel 2, so that the cleaning module 3 rotates and vibrates, thereby enabling the surface of the cleaning module 3 to also form an automatic cleaning effect.

[0030] like Figure 7 , Figure 8 and Figures 10-18To address the aforementioned issues, the cleaning module 3 is roller-shaped and includes a mounting shaft 8, a cleaning cotton positioning seat 9, and a cleaning cotton layer 10. Both ends of the mounting shaft 8 are integrally formed with screws 11, and the outer ends of the screws 11 are integrally formed with a primary rotating shaft 12. The primary rotating shaft 12 is rotatably mounted on a primary connecting seat 19 via a primary ball bearing 20. The mounting shaft 8 is a rod structure with a regular octagonal cross-section. The cleaning cotton positioning seat 9 is sleeved on the mounting shaft 8 and positioned by a limiting nut 21 on the screws 11. The cleaning cotton layer 10 covers the cleaning cotton positioning seat 9 in a ring. A secondary connecting seat 22 is integrally formed on the side wall of the primary connecting seat 19. A secondary rotating shaft 24 is rotatably mounted on the secondary connecting seat 22 via a secondary ball bearing 23. A secondary transmission gear 26 and a force-bearing gear 27 are mounted on shaft 24. A secondary driven gear 25 is mounted on primary shaft 12. The secondary driven gear 25 meshes with the secondary transmission gear 26. A force-bearing rack 34 is fixedly mounted on the side wall of photovoltaic mounting bracket 1 via primary connecting bracket 33. The force-bearing gear 27 and the force-bearing rack 34 are engaged. A connecting plate 28 is integrally formed on the inner side wall of primary connecting seat 19. An installation ring 29 is detachably mounted on the connecting plate 28. A primary locking groove 31 is opened on the side wall of primary shaft 12. A secondary locking groove 32 is opened on the installation ring 29. The installation ring 29 and primary shaft 12 are connected by a spiral spring 30. The inner and outer ends of the spiral spring 30 are respectively locked in the primary locking groove 31 and the secondary locking groove 32.

[0031] The working principle of energy storage devices: such as Figure 7 , Figure 8 and Figures 10-18 When the cleaning module 3 is driven to move by the drive structure 4, the force-bearing gear 27 moves along the force-bearing rack 34, thereby causing the secondary shaft 24 to rotate. The secondary transmission gear 26 drives the secondary driven gear 25, which in turn drives the primary shaft 12 to rotate. This allows the spiral spring 30 to accumulate elastic potential energy. When the force-bearing gear 27 disengages from the force-bearing rack 34, the spiral spring 30 releases its elastic potential energy, causing the cleaning module 3 to rotate and shake off the dust on its surface.

[0032] It should be noted that, such as Figure 8 and Figure 11The force-bearing gear 27 is mounted on the secondary rotating shaft 24 via a ratchet-type one-way bearing 35. When the cleaning module 3 moves from top to bottom along the photovoltaic panel 2, the force-bearing gear 27 moves along the force-bearing rack 34. At this time, the inner and outer rings of the ratchet-type one-way bearing 35 cannot rotate relative to each other. Thus, the force-bearing gear 27 drives the secondary rotating shaft 24, which in turn drives the secondary transmission gear 26. The secondary transmission gear 26 then drives the secondary driven gear 25, which in turn drives the primary rotating shaft 12 to rotate. This allows the spiral spring 30 to accumulate elastic potential energy. When the cleaning module 3 moves from bottom to top along the photovoltaic panel 2, the ratchet-type one-way bearing 35 is essentially a ball bearing. At this time, the force-bearing gear 27 rotates freely on the secondary rotating shaft 24. The ratchet-type one-way bearing 35 prevents the spiral spring 30 from being deformed and damaged due to reverse energy storage, thus effectively ensuring the service life of the spiral spring 30.

[0033] Example 3 It is understandable that in Embodiment 2, the cleaning module 3 is rotated by storing energy through the spiral spring 30 and releasing elastic potential energy through the spiral spring 30, thereby allowing the surface of the cleaning module 3 to complete self-cleaning. However, the dust generated by the cleaning module 3 during the self-cleaning process may re-scatter and fall onto the surface of the photovoltaic panel 2, thus affecting the cleaning effect on the photovoltaic panel 2.

[0034] It should be emphasized that the core improvement of this embodiment is that by setting up a dust collection device to absorb the dust thrown off the cleaning module 3, the dust scattered on the cleaning module 3 is prevented from causing secondary pollution to the photovoltaic panel 2.

[0035] like Figure 4 To solve the above problems, a vacuum cleaner head 37 is fixedly installed on the lower side of the photovoltaic mounting bracket 1 through a secondary connecting bracket 36. The vacuum cleaner head 37 is connected to the vacuum cleaner host through a vacuuming pipe 38. Both ends of the transmission screw 16 are longer than the force rack 34. When the moving seat 17 moves to the lower end of the transmission screw 16, the force gear 27 separates from the force rack 34. At this time, the cleaning module 3 moves to the air inlet position of the vacuum cleaner head 37. The air inlet cross section of the vacuum cleaner head 37 is semi-circular.

[0036] The working principle of vacuum cleaner head 37: Figure 4 The suction generated by the operation of the vacuum cleaner main unit creates negative pressure at the vacuum cleaner head 37, thereby absorbing the dust thrown off the cleaning module 3 to avoid secondary pollution caused by the dust.

[0037] It should be noted that, such as Figure 3A primary dust cover 45 is fixedly installed on the upper mounting base 13. A secondary dust cover 46 is provided on the primary dust cover 45. A flexible dust-proof membrane 47 is provided at the lower port of the secondary dust cover 46. When the moving base 17 moves to the upper end of the transmission screw 16, the cleaning module 3 moves into the cavity formed by the secondary dust cover 46 and the flexible dust-proof membrane 47. A bellows cover is provided on the outer side of the transmission screw 16. The primary dust cover 45 protects the transmission chain 44 from dust. The secondary dust cover 46 can protect the cleaning module 3 from dust when it stops running. The bellows cover can protect the guide rod 15 and the transmission screw 16 from dust.

[0038] It should be noted that a photovoltaic device integrating an automatic cleaning monitoring mechanism includes a photovoltaic module integrating the automatic cleaning monitoring mechanism. The photovoltaic device integrating the automatic cleaning monitoring mechanism also includes a power conversion module, an energy storage module, an angle adjustment module, and a monitoring module. The angle adjustment module is used to adjust the direction angle of the photovoltaic module, and the monitoring module is used to monitor the surface of the photovoltaic panel 2. The monitoring module is electrically connected to the monitoring system. The monitoring module can monitor the surface of the photovoltaic panel 2 in real time and perform directional cleaning on the surface of the photovoltaic panel 2 in a timely manner.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application.
