Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, specifically a protection device for photovoltaic modules. Background Technology

[0002] Photovoltaic modules are the core component of a solar power generation system. A photovoltaic module consists of multiple solar cells connected in series and then encapsulated for protection to form a large-area solar panel. This allows the system to convert sunlight into electricity using the photovoltaic effect. Photovoltaic modules are typically installed on rooftops or open ground to maximize the amount of sunlight they receive.

[0003] During operation, snow and sandstorms are frequently encountered. Snow or sand covering the surface of photovoltaic modules can affect sunlight penetration and power generation efficiency, and may even damage the modules. Therefore, staff need to conduct regular cleaning to maintain the surface of the photovoltaic modules.

[0004] However, cleaning the surface of photovoltaic modules manually is inefficient and poses safety hazards. Utility Model Content

[0005] This application provides a protective device for photovoltaic modules to solve the problems of low efficiency and safety hazards associated with manual cleaning of photovoltaic module surfaces.

The cleaning assembly includes a first cleaning member and multiple second cleaning members. The first cleaning member is connected to the bottom of the protective member, and each second cleaning member is connected to the side of the protective member facing the photovoltaic module. The storage assembly is installed on the back of the photovoltaic module. The drive mechanism includes a first drive assembly and two transmission members located on the first drive assembly. The protective member is located between the two transmission members and is fixedly connected to the two transmission members. The first drive assembly is configured to drive the transmission members to move relative to the photovoltaic module, thereby switching the protective member between a working position and a retracted position. In the working position, the protective member covers the front of the photovoltaic module, and the first cleaning member is located at the lower end of the photovoltaic module. In the retracted position, the protective member retracts into the storage assembly.

[0008] In one possible implementation, the protective device for photovoltaic modules provided in this application includes a first driving component comprising a driving member and a fixed shaft. The fixed end of the driving member is fixedly connected to the upper end of the photovoltaic module, and both ends of the output end of the driving member are connected to driving wheels. The fixed shaft is fixedly connected to the lower end of the photovoltaic module, and both ends of the fixed shaft are rotatably connected to transmission wheels. Each transmission component is sleeved on the driving wheel and transmission wheel located on the same side. The driving member is configured to drive the driving wheel to rotate, so that the transmission component drives the protective component to move relative to the photovoltaic module.

[0009] In one possible implementation, the protective device for photovoltaic modules provided in this application further includes a control component, which is disposed on the frame of the photovoltaic module and electrically connected to the drive component. The control component has a detector for detecting the solar irradiance. When the irradiance is less than or equal to a preset irradiance, the control component controls the drive component to open, thereby driving the protective component to move to the working position. When the irradiance is greater than the preset irradiance, the control component controls the drive component to open, thereby driving the protective component to move to the retracted position.

[0010] In one possible implementation, the protective device for photovoltaic modules provided in this application includes a protective housing for housing the module. The protective housing has a receiving cavity, and the protective housing has opposing outlets and inlets, both of which are connected to the receiving cavity.

[0013] In one possible implementation, the protective device for photovoltaic modules provided in this application further includes a guide component. The guide component includes two guide rails, which are respectively fixedly connected to both sides of the photovoltaic module. The guide rails and transmission components are arranged in a one-to-one correspondence. Multiple pulleys are provided inside the guide rails.

[0014] In one possible implementation, the protective device for photovoltaic modules provided in this application has a waterproof layer on the side of the protective member facing away from each of the second cleaning members.

The gear is fixedly connected to one of two drive wheels, and the handheld component is used to drive the gear to rotate. A protective cover is provided on the gear to prevent the handheld component from falling off.

[0017] The protective device for photovoltaic modules provided in this application comprises a cleaning component and protective components. The cleaning component includes a first cleaning component and multiple second cleaning components. The first cleaning component is connected to the bottom of the protective component, and each second cleaning component is connected to the side of the protective component facing the photovoltaic module, thereby cleaning and protecting the surface of the photovoltaic module. The driving mechanism includes a first driving component and two transmission components. Each side of the protective component is fixedly connected to one transmission component. The first driving component drives the transmission components to move relative to the photovoltaic module, switching the protective component between a working position and a retracted position. In the working position, the protective component moves from the top of the photovoltaic module to the surface of the photovoltaic module, allowing the first cleaning component and each second cleaning component to clean the surface of the photovoltaic module while simultaneously protecting it. In the retracted position, the protective component retracts into a storage component. Therefore, the protective device for photovoltaic modules provided in this application reduces labor costs, increases work efficiency, and reduces safety hazards. Attached Figure Description

[0038] Photovoltaic modules are the core component of a solar power generation system. A photovoltaic module consists of multiple solar cells connected in series and then encapsulated for protection to form a large-area solar panel. This allows the system to convert sunlight into electricity using the photovoltaic effect. Photovoltaic modules are typically installed on rooftops or open ground to maximize the amount of sunlight they receive.

[0039] During operation, snow and sandstorms are frequently encountered. Snow or sand covering the surface of photovoltaic modules can affect sunlight penetration and power generation efficiency, and may even damage the modules. Therefore, staff need to conduct regular cleaning to maintain the surface of the photovoltaic modules.

[0040] However, cleaning the surface of photovoltaic modules manually is inefficient and poses safety hazards.

[0041] In view of this, the protective device for photovoltaic modules provided in this application, by setting up a cleaning component and protective components, includes a first cleaning component and multiple second cleaning components. The first cleaning component is connected to the bottom of the protective component, and each second cleaning component is connected to the side of the protective component facing the photovoltaic module, so as to clean and protect the surface of the photovoltaic module. The driving mechanism includes a first driving component and two transmission components. Each side of the protective component is fixedly connected to a transmission component. The first driving component drives the transmission components to move relative to the photovoltaic module, so that the protective component switches between a working position and a retracted position. In the working position, the protective component moves from the top of the photovoltaic module to the surface of the photovoltaic module, so that the first cleaning component and each second cleaning component clean the surface of the photovoltaic module while protecting the photovoltaic module; in the retracted position, the protective component retracts into the storage component. Thus, the protective device for photovoltaic modules provided in this application reduces labor costs, increases work efficiency, and reduces safety hazards.

[0042] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0043] Figure 1 A diagram illustrating the usage status of a protection device for photovoltaic modules provided in an embodiment of this application; Figure 2 for Figure 1 A sectional view of section AA in the middle; Figure 3 This is an exploded view of a portion of the structure of the protection device for photovoltaic modules provided in an embodiment of this application; Figure 4 A schematic diagram of the structure for housing components in a protective device for photovoltaic modules provided in an embodiment of this application; Figure 5 This is a schematic diagram of the cleaning component and fixing parts in the protection device for photovoltaic modules provided in the embodiments of this application.

[0044] See also Figures 1 to 5This application provides a protective device for photovoltaic modules, including a drive mechanism 100, a protective member 200, a cleaning assembly 300, and a storage assembly 400. The cleaning assembly 300 includes a first cleaning member 310 and a plurality of second cleaning members 320. The first cleaning member 310 is connected to the bottom of the protective member 200, and each of the second cleaning members 320 is connected to the side of the protective member 200 facing the photovoltaic module 500. The storage assembly 400 is installed on the back of the photovoltaic module 500. The drive mechanism 100 includes a first drive assembly 110 and a storage assembly 400 located on the back of the photovoltaic module 500. The component 110 has two drive members 120, and the protective member 200 is located between the two drive members 120 and fixedly connected to the two drive members 120. The first drive component 110 is configured to drive the drive members 120 to move relative to the photovoltaic module 500 so that the protective member 200 switches between a working position and a retracted position. In the working position, the protective member 200 covers the front of the photovoltaic module 500, and the first cleaning member 310 is located at the lower end of the photovoltaic module 500. In the retracted position, the protective member 200 is retracted into the storage component 400.

[0045] It should be noted that the photovoltaic module 500 has a front and a back. The front of the photovoltaic module 500 faces the sunlight, and the back of the photovoltaic module 500 faces the ground.

[0046] It should also be noted that the photovoltaic module 500 has an upper end and a lower end, and the photovoltaic module 500 is generally inclined from the upper end to the lower end.

[0047] In this application, precise control of the protective component 200 is achieved through the drive mechanism 100. The first drive assembly 110 and the transmission component 120 work together to ensure smooth switching of the protective component 200 between the working position and the retracted position. This flexible switching design allows the protective device to adapt to different working requirements, improving its practicality and flexibility.

[0048] When the photovoltaic module 500 is in its working position, that is, when the cleaning component 300 and the protective component 200 are needed to clean and protect the photovoltaic module 500, the first drive component 110 drives the transmission component 120 to move the protective component 200 relative to the photovoltaic module 500. The protective component 200 moves from the upper end to the lower end of the photovoltaic module 500 until it covers the front of the photovoltaic module 500. The protective component 200 provides a protective barrier for the photovoltaic module 500, resisting the invasion of external pollutants such as rain, snow, sand, and bird droppings, thereby reducing the cleaning frequency and maintenance cost of the photovoltaic module 500. At the same time, as the protective component 200 moves from the upper end to the lower end of the photovoltaic module 500, the first cleaning component 310 also moves with the protective component 200 from the upper end to the lower end of the photovoltaic module 500. Thus, the first cleaning component 310 can clean the accumulated dust and dirt on the surface of the photovoltaic module 500 during the movement, improving the working efficiency and service life of the photovoltaic module 500.

[0049] In this design, as the protective component 200 moves from the upper end to the lower end of the photovoltaic module 500, multiple second cleaning components 320 connected to the side of the protective component 200 facing the photovoltaic module 500 also move along with it. Thus, each second cleaning component 320 further cleans the surface of the photovoltaic module 500 during its movement. This design improves cleaning efficiency, ensures the cleanliness of the photovoltaic module 500 surface, and thereby enhances the power generation efficiency of the photovoltaic module 500. It also avoids the safety hazards associated with manual cleaning of the photovoltaic module 500.

[0050] It is understood that the number and layout of the second cleaning component 320 are given only as an example, and the specific configuration can be set according to actual needs. This embodiment does not impose any limitations on this.

[0051] The protective component 200 can be a protective cloth with a certain degree of flexibility, so that it can cover the front of the photovoltaic module 500 or be retracted into the storage component 400 under the drive of the transmission component 120.

[0052] For example, when the protective component 200 is in the retracted position, the first drive assembly 110 drives the transmission component 120 to retract the protective component 200 into the storage assembly 400. The storage assembly 400 is located on the back of the photovoltaic module 500, and provides a dry and dust-free storage environment for the protective component 200, effectively preventing the protective component 200 from being disturbed by external dust, rainwater and other pollutants during storage.

[0053] The transmission component 120 can be a conveyor belt, which is safe to operate and easy to use. The conveyor belt is wrapped around both sides of the photovoltaic module 500 and passes through the storage component 400. Thus, the conveyor belt smoothly drives the protective component 200 to switch between the working position and the retracted position.

[0054] In some embodiments, the housing component 400 may be connected to the frame or support structure of the photovoltaic module 500. The photovoltaic module 500 is typically mounted on a frame or support structure made of metal or other robust materials, which provides a stable mounting base. The housing component 400 may be connected to these frames or support structures via bolts, clips, or other fasteners to ensure a secure mounting of the housing component 400 on the back of the photovoltaic module.

[0055] See also Figure 1 and Figure 2 In this embodiment, the first drive assembly 110 includes a drive member 111 and a fixed shaft 112. The fixed end of the drive member 111 is fixedly connected to the upper end of the photovoltaic module 500, and both ends of the output end of the drive member 111 are connected to drive wheels 113. The fixed shaft 112 is fixedly connected to the lower end of the photovoltaic module 500, and both ends of the fixed shaft 112 are rotatably connected to transmission wheels 114. Each transmission member 120 is sleeved on the drive wheel 113 and transmission wheel 114 located on the same side. The drive member 111 is configured to drive the drive wheel 113 to rotate, so that the transmission member 120 drives the protective member 200 to move relative to the photovoltaic module 500.

[0056] In a specific implementation, the fixed end of the driving component 111 is used to be fixedly connected to the upper end of the photovoltaic module 500. For example, a fixing plate or bracket can be provided at the upper end of the photovoltaic module 500, and the fixed end of the driving component 111 is connected to the fixing plate or bracket by welding. Alternatively, the fixed end of the driving component 111 can also be securely mounted on the photovoltaic module 500 through other connection methods to ensure the stability and reliability of the driving component 111. This embodiment does not impose any limitations on this.

[0057] Meanwhile, both ends of the output of the drive component 111 are connected to drive wheels 113. The design of dual drive wheels 113 not only enhances the driving force but also makes the transmission smoother, reducing vibration and noise caused by transmission instability. The drive component 111 can be a motor, which has the characteristics of strong controllability and smooth operation, and can stably output power.

[0058] Furthermore, the fixed shaft 112 is fixedly connected to the lower end of the photovoltaic module 500, providing stable support for the transmission wheel 114. A fixing plate or bracket can be provided at the lower end of the photovoltaic module 500, and the fixed shaft 112 is connected to the fixing plate or bracket by welding. Alternatively, the fixed shaft 112 can be securely mounted on the photovoltaic module 500 through other connection methods; this embodiment does not impose any limitations on this method.

[0059] It should be noted that the transmission wheel 114 and the drive wheel 113 are connected by the transmission component 120, forming a complete transmission system. This makes the movement of the protective component 200 more precise and controllable, effectively avoiding problems such as positional deviation or poor movement of the protective component due to transmission errors.

[0060] The transmission wheel 114 and the fixed shaft 112 can be connected by a bearing. The bearing acts as an intermediary between the transmission wheel 114 and the fixed shaft 112, which can reduce the friction between the transmission wheel 114 and the fixed shaft 112, reduce energy loss, make the transmission wheel 114 rotate more smoothly, and help improve the working efficiency of the protection device.

[0061] In this application, the driving component 111 is configured to drive the driving wheel 113 to rotate, thereby causing the transmission component 120 and the protective component 200 to move relative to the photovoltaic module 500 to meet the need for switching the position of the protective component 200. At the same time, the driving force of the driving component 111 can be adjusted as needed to achieve precise control of the moving speed and position of the protective component 200, thereby improving the working efficiency and reliability of the protection device.

[0062] See also Figures 1 to 3 In this embodiment, a control component 600 is also included. The control component 600 is disposed on the frame of the photovoltaic module 500 and electrically connected to the drive component 111. The control component 600 has a detector 610 for detecting the solar irradiance. When the irradiance is less than or equal to a preset irradiance, the control component 600 controls the drive component 111 to turn on, thereby driving the protective component 200 to move to the working position. When the irradiance is greater than the preset irradiance, the control component 600 controls the drive component 111 to turn on, thereby driving the protective component 200 to move to the retracted position.

[0063] It should be noted that the control unit 600 enables automated management of the photovoltaic module 500. Specifically, the detector 610 on the control unit 600 can detect the solar irradiance in real time and automatically adjust the position of the protective element 200 according to changes in irradiance. This design improves the working efficiency of the protection device.

[0064] In practical implementation, the introduction of the control component 600 enables the photovoltaic module 500 to automatically activate the drive component 111 when the irradiance is low, driving the protective component 200 to move to the working position and stopping the drive component 111. When the irradiance is less than or equal to the preset irradiance, the protective component 200 can move to the working position, effectively shielding the photovoltaic module 500 from external pollutants such as rain, snow, sand, and bird droppings, thereby reducing the cleaning frequency and maintenance costs of the photovoltaic module 500. This also extends the service life of the photovoltaic module 500 and improves the long-term operational stability of the photovoltaic module 500.

[0065] Understandably, when the irradiance recovers to a level higher than the preset irradiance, the controller 600 can control the drive component 111 to open, and the drive component 111 stops after the drive protection component 200 moves to the retracted position, allowing the photovoltaic module 500 to fully receive sunlight and perform efficient energy conversion. This flexible adjustment method ensures that the photovoltaic module 500 can fully utilize its performance and improve power generation efficiency under good lighting conditions.

[0066] Among them, the preset irradiance refers to the pre-set irradiance threshold, which is used to determine whether the current irradiance conditions are suitable for the photovoltaic module 500 to perform normal power generation.

[0067] See also Figure 1 , Figure 2 and Figure 4 In this embodiment of the application, the housing component 400 includes a protective housing 410, which has a receiving cavity 411. The protective housing 410 has an outlet 412 and an inlet 413, both of which are connected to the receiving cavity 411. The receiving cavity 411 is used to receive the protective component 200.

[0068] Understandably, the protective housing 410 provides a safe and stable storage space for the protective component 200. The design of the receiving cavity 411 ensures that the protective component 200 can be safely stored in the protective housing 410 when not in use, preventing the protective component 200 from being corroded and damaged by the external environment such as dust and rain. This helps to extend the service life of the protective component 200 and reduce maintenance costs.

[0069] Furthermore, the inlet design on the protective housing 410 makes it convenient and quick for the protective component 200 to enter and exit. By controlling the operation of the drive component 111, the protective component 200 can be easily moved out of the receiving cavity 411 or retracted from the outside, realizing the automated management of the protective component 200.

[0070] The protective housing 410 can be made of high-strength, corrosion-resistant materials to ensure that the protective housing 410 has good protective performance and durability, so as to effectively protect the protective component 200 from the damage of the external environment.

[0071] It should be noted that the protective housing 410 has an outlet 412 opposite to the inlet 413. When the protective component 200 is retracted into the receiving cavity 411 through the inlet 413, external pollutants such as sand and dust on the protective component 200 can fall off through the outlet 412 to avoid accumulating inside the protective housing 410.

[0072] See also Figure 1 , Figure 2 and Figure 4 In this embodiment of the application, a cleaning component 420 is fixedly connected to the inner wall of the receiving cavity 411. The cleaning component 420 is used to clean each of the second cleaning components 320.

[0073] Since the second cleaning component 320 directly contacts the surface of the photovoltaic module 500, it easily accumulates dust and dirt during operation. If not cleaned promptly, this not only affects the cleaning effect of the second cleaning component 320 but may also cause secondary pollution to the photovoltaic module 500. Therefore, a dust removal component 420 is fixedly connected to the inner wall of the receiving cavity 411 to effectively clean the second cleaning component 320 after each component completes its cleaning task.

[0074] In this application, by fixing the cleaning component 420 to the inner wall of the receiving cavity 411, an automated cleaning process can be achieved. When the protective component 200 and the second cleaning component 320 are returned to the receiving cavity 411, the cleaning component 420 automatically cleans the second cleaning component 320 without manual operation. This not only improves cleaning efficiency but also reduces the cost and complexity of manual maintenance.

[0075] See also Figure 2 and Figure 5 In this embodiment, the cleaning component 420 is a scraper, the first cleaning component 310 is a scraper, and the second cleaning component 320 is a brush.

[0076] In some embodiments, the cleaning element 420 is designed as a scraper blade, capable of effectively scraping away dust and dirt from the second cleaning element 320. The scraper blade typically has sharp edges and a certain degree of hardness, allowing it to penetrate deep into the fibers of the brush to remove accumulated dust. This design ensures that the cleaning element 420 cleans the second cleaning element 320 efficiently and thoroughly, guaranteeing that the second cleaning element 320 returns to a clean state after use, thus ensuring the continuous cleaning effect of each second cleaning element 320.

[0077] In this application, the first cleaning component 310 is designed as a scraper, which can form a tight fit with the surface of the photovoltaic module 500 to effectively scrape away snow, dust, dirt, etc. from the surface of the photovoltaic module 500. The scraper can be made of a material with high wear resistance and corrosion resistance, which can resist the erosion of rainwater, thereby extending the service life of the scraper. The scraper typically has a large contact area and moderate hardness to ensure that the surface of the photovoltaic module 500 is not damaged during the cleaning process, while thoroughly removing stains.

[0078] The second cleaning component 320 is designed as a brush to clean the surface of the photovoltaic module 500 using its bristles. The brush has good flexibility and adhesion, and when used in conjunction with the scraper, it complements the cleaning process to ensure a thorough cleaning of the photovoltaic module 500 surface.

[0079] It should be noted that when the protective component 200 covers the front of the photovoltaic module 500, the brush matrix formed by the second cleaning component 320 on the protective component 200 can bear a certain load to prevent rain and snow from pressing on the photovoltaic module 500 and causing damage to the photovoltaic module 500.

[0080] See also Figure 1 and Figure 2 In this embodiment of the application, a guide component 700 is also included. The guide component 700 includes two guide rails 710, which are respectively used to be fixedly connected to both sides of the photovoltaic module 500. The guide rails 710 and the transmission component 120 are respectively arranged in a one-to-one correspondence. Multiple pulleys 720 are provided in the guide rails 710.

[0081] In practice, two guide rails 710 are fixedly connected to both sides of the photovoltaic module 500 and are correspondingly set with the transmission component 120, thereby ensuring the stability and accuracy of the transmission component 120 during movement. The guide rails 710, as the running track of the transmission component 120, can limit the direction of movement of the transmission component 120, preventing it from deviating or swaying during movement, thus improving the stability and reliability of the protection device.

[0082] Furthermore, the multiple pulleys 720 installed within the guide rail 710 effectively reduce the frictional resistance of the transmission component 120 during movement. The pulleys 720 serve as contact points between the transmission component 120 and the guide rail 710, allowing the transmission component 120 to move smoothly along the guide rail 710. This not only improves transmission efficiency but also reduces energy loss.

[0083] The pulley 720 can be connected to the guide rail 710 using a connecting member such as a bolt, and the pulley 720 can rotate relative to the connecting member. The number and layout of the pulleys 720 are only given as an example, and the specific configuration can be set according to actual needs. This embodiment does not impose any limitations on this.

[0084] In this embodiment, the protective member 200 has a waterproof layer on the side facing away from each of the second cleaning members 320.

[0085] It should be noted that the waterproof layer (not shown in the figure) effectively prevents moisture from penetrating onto the photovoltaic module 500 through the protective component 200. By forming a barrier on the protective component 200 through the waterproof layer, rainwater is isolated from the outside, improving the protective effect of the protective component 200 on the photovoltaic module 500.

[0086] See also Figure 5 In this embodiment of the application, a fixing member 800 is also included. The fixing member 800 has a connecting part 810 and a clamping part 820 fixedly connected to the connecting part 810. The connecting part 810 is detachably connected to the protective member 200. The first cleaning member 310 is inserted into the clamping part 820.

[0087] Understandably, the connecting part 810 and the protective part 200 are detachably connected, allowing workers to easily separate the fixing part 800 from the protective part 200 when needed for cleaning, replacement, or maintenance. Specifically, the connecting part 810 may have multiple first connecting holes, and the protective part 200 may have multiple second connecting holes at one end near the connecting part 810. The first and second connecting holes correspond one-to-one, and connectors such as bolts and nuts can be used to connect the first and second connecting holes, achieving a stable connection between the connecting part 810 and the protective part 200.

[0088] In this application, the clamping part 820 allows the first cleaning member 310 to be stably inserted into the clamping part 820. Specifically, the clamping part 820 may have multiple third connecting holes, and the first cleaning member 310 may have multiple fourth connecting holes. Connectors, such as bolts and nuts, can be used to connect the third connecting holes and the fourth connecting holes, ensuring that the first cleaning member 310 can be firmly fixed on the clamping part 820 and is not easy to fall off or shift. This stability ensures that the first cleaning member 310 can maintain the correct position and angle during operation, thereby effectively removing dust and stains from the surface of the photovoltaic module 500. The connectors can be bolts and nuts, and there can be multiple third and fourth connecting holes; this embodiment does not impose any limitations on this.

[0089] See also Figures 1 to 3 In this embodiment of the application, the drive mechanism 100 further includes a second drive component 130, which includes a gear 131 and a handheld component 132 connected to the gear 131. The gear 131 is fixedly connected to one of the two drive wheels 113, and the handheld component 132 is used to drive the gear 131 to rotate. A protective cover is provided on the gear 131 to prevent the handheld component 132 from falling off.

[0090] In some embodiments, the second drive assembly 130 provides a manual operation option for the operator, improving the flexibility and adaptability of the protection device. Using the handheld component 132, the operator can directly drive the gear 131 to rotate, thereby controlling the rotation of the drive wheel 113. Thus, in the event of insufficient power supply or system failure, the operator can continue to complete cleaning and protection tasks manually, ensuring the continuity and reliability of the protection device.

[0091] Furthermore, the fixed connection between gear 131 and drive wheel 113 ensures efficient power transmission. As a highly efficient transmission mechanism, gear 131 converts the rotation of the handheld component 132 into the rotation of the drive wheel 113, achieving smooth power transmission. This design not only improves transmission efficiency but also reduces energy loss, making the entire protection device operate more efficiently.

[0092] It should be noted that the protective cover (not shown in the figure) effectively prevents the handpiece 132 from falling off. During operation, the handpiece 132 may accidentally fall off due to vibration, impact, or other external factors, causing operation to be interrupted. The presence of the protective cover can limit the handpiece 132 to the gear 131, preventing the handpiece 132 from accidentally falling off, thereby improving the safety and stability of the protective device.

[0093] The shield may have an opening or a slot to allow the handpiece 132 to pass through the shield and connect with the gear 131, while preventing the handpiece 132 from accidentally falling off. This embodiment does not limit this.

[0094] In summary, the protective device for photovoltaic modules provided in this application, by setting up a cleaning component 300 and a protective component 200, the cleaning component 300 includes a first cleaning component 310 and a plurality of second cleaning components 320. The first cleaning component 310 is connected to the bottom of the protective component 200, and each second cleaning component 320 is connected to the side of the protective component 200 facing the photovoltaic module 500, so as to clean and protect the surface of the photovoltaic module 500. The drive mechanism 100 includes a first drive assembly 110 and two transmission members 120. Each side of the protective member 200 is fixedly connected to one of the transmission members 120. The first drive assembly 110 drives the transmission members 120 to move relative to the photovoltaic module 500, allowing the protective member 200 to switch between a working position and a retracted position. In the working position, the protective member 200 moves from the upper end of the photovoltaic module 500 to its surface, allowing the first cleaning member 310 and each of the second cleaning members 320 to clean the surface of the photovoltaic module 500 while the protective member 200 protects the photovoltaic module 500. In the retracted position, the protective member 200 retracts into the storage assembly 400. Therefore, the protective device for photovoltaic modules provided in this application reduces labor costs, increases work efficiency, and reduces safety hazards.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
