DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] 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 term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0036] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a photovoltaic panel protection device, which includes: a covering component 100 and a pressing component 200.

[0037] Specifically, the covering assembly 100 includes a storage part 101 and an antifreeze cloth 102, which is used to cover the photovoltaic panel G with a layer of antifreeze cloth 102 to reduce the impact of frost, snow or ice, and prevent ice from forming on the photovoltaic panel G. The antifreeze cloth 102 can be made of thermoplastic polyurethane coated cloth, which has strong waterproof, dustproof and wear resistance, and is resistant to low temperatures, and can remain flexible in an environment of minus 40 degrees; it can also be made of polytetrafluoroethylene coated cloth, which has excellent waterproof, antifouling and oil-proof properties, and has an extremely low surface friction coefficient, which can prevent snow and ice from adhering. When not in use, the antifreeze cloth 102 is retracted into the storage part 101 to avoid affecting the power generation of the photovoltaic panel G. The storage part 101 is arranged on the top of the photovoltaic panel G to facilitate covering the photovoltaic panel G with cloth. The antifreeze cloth 102 is arranged in the storage part 101. There is a rotating shaft in the storage part 101, and the rotating shaft is driven to rotate by an external power. Since the photovoltaic panel G is generally not installed horizontally, the storage part 101 is installed on the top of the photovoltaic panel G, and the gravity and the external power of the rotating shaft are used to drive the rotating shaft to rotate and release the soft antifreeze cloth 102.

[0038] Specifically, the clamping assembly 200 is used to ensure that the antifreeze cloth 102 fits the photovoltaic panel G. Since the antifreeze cloth 102 has a certain thickness and is stored in the storage component 101 when not in use, the storage component 101 has a certain size. When releasing the antifreeze cloth 102, there are two options. One is that the side of the antifreeze cloth 102 facing away from the photovoltaic panel G is close to the rotating axis of the storage component 101 when rolled up for storage. In this case, the accumulated debris on the antifreeze cloth 102 is likely to be rolled into the storage component 101, and while the antifreeze cloth 102 is close to the storage component 101, it is still very close to the photovoltaic panel G, making it inconvenient to clean the antifreeze cloth 102.

[0039] Therefore, the present device chooses to make the side of the antifreeze cloth 102 facing away from the photovoltaic panel G away from the rotating axis of the storage component 101 when rolled up for storage, and at the same time uses other parts to make the antifreeze cloth 102 fit the photovoltaic panel G. This other part is arranged at one end of the covering assembly 100, including a fixed rod 201 and a rotating rod 202. The fixed rod 201 is fixedly connected to one end of the antifreeze cloth 102. The fixed rod 201 is at the top of the antifreeze cloth 102, and the rotating rod 202 rotates and cooperates with the end of the fixed rod 201. There are multiple rotating rods 202. When the storage component 101 falls to release the antifreeze cloth 102, the rotating rods 202 will unfold to cover both sides of the antifreeze cloth 102.

[0040] When in use, the fixing rod 201 is fixed on the top of the antifreeze cloth 102; as the storage part 101 falls, the antifreeze cloth 102 is released from the storage part 101, and the bottom of the released antifreeze cloth 102 is the storage part 101. The two sides of the antifreeze cloth 102 are pressed by the rotating rod 202, so that the four sides of the antifreeze cloth 102 are all pressed, completely covering the photovoltaic panel G, which can prevent frost from forming on the photovoltaic panel and improve the protection effect of the antifreeze cloth 102.

[0041] Example 2, reference Figure 1 to Figure 8 , which is the second embodiment of the present invention, and is based on the previous embodiment. This embodiment provides a photovoltaic panel protection device, including a covering assembly 100, a pressing assembly 200 and a cleaning assembly 300.

[0042] Specifically, the covering assembly 100 includes a storage part 101 and an antifreeze cloth 102, which is used to cover the photovoltaic panel G with a layer of antifreeze cloth 102 to reduce the impact of frost, snow or ice, and prevent ice from forming on the photovoltaic panel G. The antifreeze cloth 102 can be made of thermoplastic polyurethane coated cloth, which has strong waterproof, dustproof and wear resistance, and is resistant to low temperatures and can remain flexible in an environment of -40 degrees; it can also be made of polytetrafluoroethylene coated cloth, which has excellent waterproof, antifouling and oil-proof properties, and has an extremely low surface friction coefficient, which can prevent snow and ice from adhering. When not in use, the antifreeze cloth 102 is retracted into the storage part 101 to avoid affecting the power generation of the photovoltaic panel G. The storage part 101 is arranged on the top of the photovoltaic panel G to facilitate covering the photovoltaic panel G with cloth. The antifreeze cloth 102 is arranged in the storage part 101. There is a rotating shaft in the storage part 101, and the rotating shaft is driven to rotate by an external power. Since the photovoltaic panel G is generally not installed horizontally, the storage part 101 is installed on the top of the photovoltaic panel G, and gravity is used to fall and release the soft antifreeze cloth 102.

[0043] Specifically, the clamping assembly 200 is used to ensure that the antifreeze cloth 102 fits the photovoltaic panel G. Since the antifreeze cloth 102 has a certain thickness and is stored in the storage component 101 when not in use, the storage component 101 has a certain size. When releasing the antifreeze cloth 102, there are two options. One is that the side of the antifreeze cloth 102 facing away from the photovoltaic panel G is close to the rotating axis of the storage component 101 when rolled up for storage. In this case, the accumulated debris on the antifreeze cloth 102 is likely to be rolled into the storage component 101, and while the antifreeze cloth 102 is close to the storage component 101, it is still very close to the photovoltaic panel G, making it inconvenient to clean the antifreeze cloth 102. Similarly, the present device selects to make the side of the antifreeze cloth 102 facing away from the photovoltaic panel G away from the rotating axis of the storage component 101 when rolled up for storage, and at the same time uses other parts to make the antifreeze cloth 102 fit the photovoltaic panel G. This other part is arranged at one end of the covering assembly 100, including a fixed rod 201 and a rotating rod 202. The fixed rod 201 is fixedly connected to one end of the antifreeze cloth 102. The fixed rod 201 is at the top of the antifreeze cloth 102, and the rotating rod 202 rotates and cooperates with the end of the fixed rod 201. There are multiple rotating rods 202. When the storage component 101 falls to release the antifreeze cloth 102, the rotating rods 202 will unfold to cover both sides of the antifreeze cloth 102.

[0044] Specifically, the cleaning assembly 300 is used to clean the photovoltaic panel G and the antifreeze cloth 102, and is arranged on the top of the covering assembly 100, and includes a direction adjustment member 301 and a cleaning member 302. The direction adjustment member 301 is arranged on the side of the covering assembly 100, and the cleaning member 302 is attached to the photovoltaic panel G. The direction adjustment member 301 controls the position of the cleaning member 302, and the part of the cleaning member 302 that contacts the antifreeze cloth 102 or the photovoltaic panel G is a brush or an air hole, which is used to clean the antifreeze cloth 102 or the photovoltaic panel G. Since the photovoltaic panel G and the antifreeze cloth 102 are parallel but not on the same layer, and the cleaning piece 302 is installed on the storage piece 101, the cleaning piece 302 is equipped with an adjusting piece 301. When the storage piece 101 covers the photovoltaic panel G with cloth, the adjusting piece 301 adjusts the cleaning piece 302 on the photovoltaic panel G to clean the photovoltaic panel G, keep the surface of the photovoltaic panel G clean, improve the fitting effect of the antifreeze cloth 102, and avoid the influence of debris; when the storage piece 101 retracts the antifreeze cloth 102, the adjusting piece 301 adjusts the cleaning piece 302 on the antifreeze cloth 102, so that the recovered antifreeze cloth 102 will not be caught in debris, and the exposed surface of the antifreeze cloth 102 is kept clean, to avoid the antifreeze cloth 102 being unable to be recycled.

[0045] When in use, when covering the cloth, the fixing rod 201 is fixed on the top of the antifreeze cloth 102; the storage part 101 is at the bottom of the antifreeze cloth 102, and the rotating rods 202 are on both sides of the antifreeze cloth 102. When the storage part 101 falls, the direction adjustment part 301 allows the cleaning part 302 to fit the photovoltaic panel G, and clean the photovoltaic panel G before the antifreeze cloth 102 covers the photovoltaic panel G, so that the photovoltaic panel G remains clean and fits the antifreeze cloth 102 with four edges pressed, avoiding frost from forming on the photovoltaic panel G, and improving the protective effect of the antifreeze cloth 102. When collecting the cloth, the direction adjustment part 301 adjusts the cleaning part 302 to fit the antifreeze cloth 102, cleans the antifreeze cloth 102, and then collects it in the storage part 101, so as to avoid debris affecting the life and storage of the antifreeze cloth 102.

[0046] Example 3, reference Figure 1 to Figure 9 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0047] This embodiment provides a photovoltaic panel protection device, including a covering assembly 100 , a pressing assembly 200 and a cleaning assembly 300 .

[0048] Specifically, the covering assembly 100 further includes a pressing rod 103 and a connecting rod 104. There are two pressing rods 103, which are arranged on both sides of the antifreeze cloth 102. One end of the connecting rod 104 is fixedly connected to the end of the pressing rod 103, and the other end is matched with the side of the storage member 101. The two pressing rods 103 clamp the antifreeze cloth 102, so that the antifreeze cloth 102 is kept at a certain distance from the photovoltaic panel G when covering the cloth. At the same time, due to the rotation direction of the antifreeze cloth 102 in the storage member 101, the distance between the antifreeze cloth 102 and the photovoltaic panel G will be very high when the antifreeze cloth 102 just comes out of the storage member 101, so the pressing rod 103 can also quickly shorten the distance between the antifreeze cloth 102 and the photovoltaic panel G.

[0049] The connecting rod 104 connects the pressing rod 103 and the side surface of the storage member 101 , and can be driven by an external power to swing, so as to clean the impurities on the antifreeze cloth 102 .

[0050] Specifically, the covering assembly 100 further includes a follower pressure block 105, the middle of which is sleeved on the two ends of the clamping rod 103 away from the photovoltaic panel G, and the side of the follower pressure block 105 is rotatably connected to the end of the rotating rod 202. The clamping assembly 200 further includes a fixed pressure block 203, the middle of which is sleeved on the two ends of the fixed rod 201, and the side of the fixed pressure block 203 is rotatably connected to the end of the rotating rod 202.

[0051] Specifically, there are two groups of rotating rods 202, each group has two rods, and the fixed pressing block 203 cooperates with the follower pressing block 105 through the two rotating rods 202; the pressing assembly 200 also includes a mounting clamp 204 and a limiting rod 205, the mounting clamp 204 is fixed to the corner of the photovoltaic panel G, and the limiting rod 205 is fixed to the side of the photovoltaic panel G and cooperates with the mounting clamp 204. The fixed rod 201 is fixed to the top of the antifreeze cloth 102 through the mounting clamp 204.

[0052] There are two rotating rods 202 between the follower pressure block 105 and the fixed pressure block 203. The four parts are connected end to end in a rotating manner. When the storage component 101 is at the top of the photovoltaic panel G, the two rotating rods 202 almost overlap and are in a horizontal state. When the storage component 101 descends to the bottom of the photovoltaic panel G, the two rotating rods 202 unfold and are parallel to the side of the photovoltaic panel G, and press down the two side surfaces of the antifreeze cloth 102, thereby improving the protective effect of the antifreeze cloth 102.

[0053] Specifically, the covering assembly 100 further includes a covering support frame 106, the covering support frame 106 and the limiting rod 205 are slidably matched, and the top of the covering support frame 106 and the storage member 101 are fixedly matched. The covering support frame 106 is used to support the storage member 101, and cooperates with the limiting rod 205 to make the antifreeze cloth 102 better fit the photovoltaic panel G.

[0054] Specifically, the pressing assembly 200 further includes an anti-pressure rod 206 and a pressing support frame 207. The anti-pressure rod 206 and the connection between the two rotating rods 202 are slidably matched; the pressing support frame 207 and the limit rod 205 are slidably matched, and the top of the pressing support frame 207 and the end of the anti-pressure rod 206 are matched. The anti-pressure rod 206 connects and supports the two rotating rods 202 at the connection between the two rotating rods 202, ensuring that the rotating rod 202 will not press the antifreeze cloth 102 against the photovoltaic panel G due to its own weight, thereby avoiding friction between the antifreeze cloth 102 and the photovoltaic panel G.

[0055] Specifically, the direction-adjusting member 301 includes a first gear 301a and a second gear 301b. The first gear 301a matches with the side of the storage member 101, the second gear 301b meshes with the first gear 301a, and the second gear 301b fits with the end of the cleaning member 302.

[0056] When the rotating shaft in the storage member 101 rotates, it drives the first gear 301 a , so that the second gear 301 b meshing with the first gear 301 a rotates in the opposite direction to the rotating shaft.

[0057] Specifically, the direction adjusting member 301 further includes a conical spring 301c and a blocking block 301d. The bottom of the conical spring 301c is fixedly connected to the end of the cleaning member 302. The bottom of the blocking block 301d is arranged on the top of the conical spring 301c. The top of the blocking block 301d cooperates with the second gear 301b.

[0058] When the second gear 301b rotates, it will contact the top of the blocking block 301d, thereby driving the cleaning member 302 installed with the conical spring 301c. In this way, when the storage member 101 falls and covers the cloth, the cleaning member 302 rotates around the rotation axis of the storage member 101 and fits the photovoltaic panel G. Then the cleaning member 302 can no longer continue to rotate around the rotation axis of the storage member 101, but the second gear 301b will continue to rotate, so the conical spring 301c will continue to bend under force until the blocking block 301d is separated from the teeth of the second gear 301b. Then the blocking block 301d will enter another teeth of the second gear 301b. At this time, the blocking block 301d will bend. 01d will repeatedly contact the teeth of the second gear 301b. At this time, the second gear 301b is relative to the ratchet teeth of the ratchet wrench, and the blocking block 301d is the pawl. In this case, the rotation of the second gear 301b will allow the cleaning member 302 to press on the photovoltaic panel G with a certain pressure to clean the photovoltaic panel G. When the storage member 101 rises to collect the cloth, the rotation of the second gear 301b will allow the cleaning member 302 to press on the antifreeze cloth 102 with a certain pressure to clean the antifreeze cloth 102.

[0059] When in use, when covering the cloth, the fixing rod 201 is fixed on the top of the antifreeze cloth 102; the storage part 101 is at the bottom of the antifreeze cloth 102, and the rotating rods 202 are on both sides of the antifreeze cloth 102. When the storage part 101 falls, the rotating shaft of the storage part 101 drives the first gear 301a to rotate, and drives the blocking block 301d to rotate through the second gear 301b, so that the cleaning part 302 rotates until the cleaning part 302 fits the photovoltaic panel G. Before the antifreeze cloth 102 covers the photovoltaic panel G, the photovoltaic panel G is cleaned, so that the photovoltaic panel G remains clean and fits the antifreeze cloth 102 with all four edges pressed, avoiding frost from forming on the photovoltaic panel G, and improving the protection effect of the antifreeze cloth 102. When collecting the cloth, the direction adjusting part 301 adjusts the cleaning part 302 to fit the antifreeze cloth 102, cleans the antifreeze cloth 102 and then collects it in the storage part 101, so as to avoid debris affecting the life and storage of the antifreeze cloth 102.

[0060] Example 4, reference Figure 1 to Figure 9 , which is the fourth embodiment of the present invention, and this embodiment is based on the previous two embodiments.

[0061] This embodiment provides a method for using a photovoltaic panel protection device, including unfolding an antifreeze cloth on a photovoltaic panel; and folding the antifreeze cloth from the photovoltaic panel.

[0062] Specifically, unfolding the antifreeze cloth on the photovoltaic panel includes: driving the storage member 101 to descend along the photovoltaic panel G, allowing the antifreeze cloth 102 to be unfolded and covered on the photovoltaic panel G, maintaining a safe distance between the storage member 101 and the photovoltaic panel G to prevent damage to the surface of the photovoltaic panel G, and at the same time, the cleaning member 302 is driven by the adjustment member 301 to fit the surface of the photovoltaic panel G, and before the antifreeze cloth 102 covers the photovoltaic panel G, dust, snow or other debris on the surface of the photovoltaic panel G is cleaned to improve the protective effect of the photovoltaic panel, and after the antifreeze cloth 102 covers the photovoltaic panel G, the rotating rod 202 rotates and unfolds to both sides of the photovoltaic panel G, pressing both sides of the antifreeze cloth 102, so that the antifreeze cloth 102 completely fits the photovoltaic panel G, to ensure that it can maintain a fit state under the action of wind or external force, and avoid gaps or rolling up;

[0063] Specifically, the process of retracting the antifreeze cloth from the photovoltaic panel includes driving the storage component 101 to retract the antifreeze cloth 102. At the same time, in the initial stage of the antifreeze cloth 102 entering the storage component 101, the cleaning component 302 is driven by the adjustment component 301 to contact the antifreeze cloth 102, thereby cleaning the dust, debris or other debris on the surface of the antifreeze cloth 102 to prevent the accumulation of debris from affecting the storage effect. At the same time, the rotating rod 202 is rotated and retracted toward the middle of the photovoltaic panel G, releasing the pressure on the side of the antifreeze cloth 102, so that the antifreeze cloth 102 can be smoothly rolled back into the storage component.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
