Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic modules, and in particular to photovoltaic modules and snow shielding devices thereof. Background Art

[0002] Currently, most household photovoltaic systems are installed on rooftops. During the winter, a large amount of snow accumulates on the photovoltaic surfaces of the rooftops. When the sun comes out the next day and the ambient temperature rises, the bottom of the snow on the photovoltaic panels in the photovoltaic modules melts, causing a large amount of snow to slide off the photovoltaic panels rapidly. When the snow slides down, the impact force is huge, posing a serious threat to the safety and property of residents.

[0003] Most existing snow guards are installed by drilling holes in the photovoltaic module and then fastening them to the edge of the module. However, snap-on snow guards require a more rigid structure for the photovoltaic module, requiring two parallel thin plates to be installed at the edge of the module before snapping the snow guard onto the two plates. These existing snow guards are difficult to install, requiring high-altitude operation during installation. Their effectiveness in blocking snow is limited, and potential hazards remain when large amounts of snow fall. Utility Model Content

[0017] When the first elastic buckle and the second elastic buckle are in the first state, they protrude toward both sides of the baffle respectively, and when the third elastic buckle and the fourth elastic buckle are in the first state, they both protrude from one side of the baffle; or

[0018] When the first elastic buckle and the second elastic buckle are in the first state, they protrude toward both sides of the baffle respectively. When the third elastic buckle and the fourth elastic buckle are in the first state, they protrude toward both sides of the baffle respectively.

[0049] See Figure 2 and Figure 3 , Figure 2 and Figure 3 A structural schematic diagram of a snow-blocking device 100 in an embodiment of the present application is shown. The snow-blocking device 100 provided in an embodiment of the present application is used to be installed between two photovoltaic panels 211 of a photovoltaic assembly 210. The snow-blocking device 100 includes a baffle 113 and two groups of elastic clips 110 arranged along a first direction OX.

[0050] In the aforementioned snow-blocking device 100, the elastic clip 110 has a first end 111 and a second end 112, respectively. The first end 111 is connected to the baffle 113. The elastic clip 110 has a first state and a second state. When the elastic clip 110 is in the first state, a gap exists between the second end 112 and the baffle 113. The second end of the elastic clip 110 can move toward the baffle 113 to switch the elastic clip 110 from the first state to the second state. The specific method of movement of the elastic clip 110 is to apply an external force to overcome the elastic force of the elastic clip 110, thereby causing the second end to move toward the baffle 113. When in the second state, the elastic clip 110 is used to allow the snow-blocking device 110 to penetrate the gap between the two photovoltaic panels 211. When the elastic clips 110 are in the second state, the distance between the second ends 112 of the two sets of elastic clips 110 along the thickness direction of the photovoltaic panel 211 is equal to the thickness of the photovoltaic panel 211, so that the second ends 112 of the elastic clips 110 are respectively in contact with the upper surface or the lower surface of the photovoltaic panel, and the first direction OX is the length direction of the baffle 113. During the actual installation and use of the above-mentioned snow blocking device 100, the elastic clips 110 are retracted to the second state, and then the baffle 113 is inserted into the gap between two adjacent photovoltaic panels 211. When one set of elastic clips 110 passes through the gap between the two photovoltaic panels 211, the elastic force of the elastic clips 110 causes the elastic clips 110 to return from the second state to the first state. At this time, the two sets of elastic clips 110 arranged along the first direction OX are both in the first state, and the second ends 112 of the two sets of elastic clips 110 are in the first state. 2 along the thickness direction of the photovoltaic panel 211 is equal to the thickness of the photovoltaic panel 211, so that the photovoltaic panel 211 can be located between the two sets of elastic clips 110. Since the second end abuts against the upper surface or the lower surface of the photovoltaic panel 211, when the distance between the second ends 112 of the two sets of elastic clips 110 along the thickness direction of the photovoltaic panel 211 is equal to the thickness of the photovoltaic panel 211, the second end 112 of the elastic clip 110 abuts against the upper surface or the lower surface of the photovoltaic panel, respectively. Figure 1 The first state is the use state of the snow blocking device 100 when it is installed on the photovoltaic assembly 210. In the first state, the baffle 113 of the snow blocking device 100 can be perpendicular to the photovoltaic panel 211, that is, Figure 1In this case, the first direction is the thickness direction of the photovoltaic panel 211, and the distance between the second ends 112 of the two sets of elastic clips 110 along the thickness direction of the photovoltaic panel 211 is equal to the thickness of the photovoltaic panel 211. The baffle 113 of the snow blocking device 100 can be inclined relative to the photovoltaic panel 211, that is, the baffle 113 is not perpendicular to the photovoltaic panels 211 after being inserted into the gap between the two photovoltaic panels 211. In this case, the first direction OX is not perpendicular to the photovoltaic panels 211 but forms an angle. The distance between the second ends 112 of the two sets of elastic clips 110 along the thickness direction of the photovoltaic panel 211 is equal to the thickness of the photovoltaic panel 211, but the distance between the second ends 112 of the two sets of elastic clips 110 along the first direction OX is greater than the thickness of the photovoltaic panel 211. This allows the snow-blocking device 100 to be clipped into the gap between two adjacent photovoltaic panels 211. When accumulated snow slides down the photovoltaic panel 211, the baffle 113 of the snow-blocking device 100 can block the accumulated snow to prevent the accumulated snow from sliding down and damaging the photovoltaic panel 211 or other components or pedestrians. When it is necessary to ensure the light source illumination of the photovoltaic panel 211, one set of elastic clips 110 can be retracted from the first state to the second state, thereby releasing the elastic clips 110 from abutting the upper or lower surface of the photovoltaic panel 211, and then the snow-blocking device 100 can be removed from the photovoltaic assembly 210, thereby achieving quick installation and quick disassembly through the elastic clips 110 that can elastically change the telescopic state, thereby improving the installation and maintenance efficiency of the snow-blocking device 100 of the photovoltaic assembly 210.

[0051] Specifically, when the elastic buckle 110 is in the first state, the maximum distance of the snow-blocking device 100 along the thickness direction of the baffle 113 is greater than the width of the gap between the two photovoltaic panels 211, thereby ensuring that the snow-blocking device 100 will not fall from the gap between the two photovoltaic panels 211 when the elastic buckle 110 is in the first state.

[0052] Preferably, the distance between the second ends 112 of the two sets of elastic clips 110 along the first direction OX is equal to the thickness of the photovoltaic panel 211, so that the photovoltaic panel 211 can be just clamped between the second ends 112 of the two sets of elastic clips 110, thereby ensuring that the angle between the baffle 113 and the photovoltaic panel 211 is 90° or close to 90°, thereby ensuring that the baffle 113 is stably clamped to the photovoltaic component 210 while improving the snow blocking effect.

[0053] See Figure 2 and Figure 3In one embodiment, each of the two sets of elastic clips 110 includes at least two elastic clips 110. The at least two elastic clips 110 in each set of elastic clips 110 are arranged along the second direction OY. The first direction OX, the second direction OY, and the thickness direction of the baffle 113 are perpendicular to each other. Thus, the at least two elastic clips 110 in each set of elastic clips 110 arranged along the second direction OY can further stably limit the position of the baffle 113 in the first direction OX. That is, the four elastic clips 110 arranged along the first direction OX and the second direction OY ensure stable attachment of the photovoltaic module 210, preventing the baffle 113 from shaking perpendicular to its thickness direction.

[0054] See Figure 2 and Figure 3 In one embodiment, the two groups of elastic buckles 110 are respectively a first buckle group 120 and a second buckle group 130. In one embodiment, the first buckle group 120 includes at least a first elastic buckle 121 and a second elastic buckle 122, and the second buckle group 130 includes at least a third elastic buckle 131 and a fourth elastic buckle 132. When the first elastic buckle 121 and the second elastic buckle 122 are in the first state, they both protrude from one side of the baffle 113. When the third elastic buckle 131 and the fourth elastic buckle 132 are in the first state, they both protrude from one side of the baffle 113.

[0055] In another embodiment, the first elastic buckle 121 and the second elastic buckle 122 are both protruding from one side of the baffle 113 when in the first state, and the third elastic buckle 131 and the fourth elastic buckle 132 are respectively protruding to both sides of the baffle 113 when in the first state.

[0056] See Figure 2 and Figure 3 In another embodiment, the first elastic buckle 121 and the second elastic buckle 122 protrude toward both sides of the baffle 113 when in the first state, and the third elastic buckle 131 and the fourth elastic buckle 132 protrude from one side of the baffle 113 when in the first state. Or

[0057] In another embodiment, the first elastic buckle 121 and the second elastic buckle 122 protrude toward both sides of the baffle 113 when in the first state, and the third elastic buckle 131 and the fourth elastic buckle 132 protrude toward both sides of the baffle 113 when in the first state.

[0058] In the above embodiment, at least one side of the baffle 113 is ensured to have two elastic clips 110 located on both sides of the thickness direction of the photovoltaic panel 211, so that the baffle 113 is snapped into the gap of the photovoltaic panel 211, and the support points are surrounded by a rectangle, so that the support for the baffle 113 is more stable. When the accumulated snow hits the baffle 113, the baffle 113 will not deviate, thereby improving the snow blocking effect.

[0059] See Figure 2 and Figure 3 In one embodiment, the two side surfaces of the baffle 113 are respectively a first surface 114 and a second surface 115 .

[0060] The first elastic buckle 121 is located on one side of the first surface 114 of the baffle 113 and protrudes from the first surface 114. The second elastic buckle 122 is located on one side of the second surface 115 of the baffle 113 and protrudes from the second surface 115. The third elastic buckle 131 is located on one side of the first surface 114 of the baffle 113 and protrudes from the first surface 114. The fourth elastic buckle 132 is located on one side of the second surface 115 of the baffle 113 and protrudes from the second surface 115. The first elastic buckle 121 and the third elastic buckle 131 are arranged along the first direction OX, while the second elastic buckle 122 and the fourth elastic buckle 132 are arranged along the first direction OX. That is, the first surface 114 clamps the photovoltaic panel 211 on one side of the first surface 114 through the first elastic clip 121 and the third elastic clip 131 arranged along the first direction OX, and the second surface 115 clamps the photovoltaic panel 211 on one side of the second surface 115 through the second elastic clip 122 and the fourth elastic clip 132 arranged along the first direction OX, so that the baffle 113 is stably set in the gap between the two photovoltaic panels 211.

[0061] In another embodiment, the two side surfaces of the baffle 113 are respectively a first surface 114 and a second surface 115. A first elastic buckle 121 is located on one side of the first surface 114 of the baffle 113 and protrudes from the first surface 114. The first elastic buckle 121 is located on one side of the second surface 115 of the baffle 113 and protrudes from the first surface 114. A third elastic buckle 131 is located on one side of the first surface 114 of the baffle 113 and protrudes from the first surface 114. A fourth elastic buckle 132 is located on one side of the second surface 115 of the baffle 113 and protrudes from the first surface 114. The first elastic buckle 121 and the fourth elastic buckle 132 are arranged along the first direction OX, and the second elastic buckle 122 and the third elastic buckle 131 are arranged along the first direction OX. That is, the first surface 114 clamps the photovoltaic panel 211 on one side of the first surface 114 through the first elastic clip 121 and the third elastic clip 131 arranged at an angle to the first direction OX, and the second surface 115 clamps the photovoltaic panel 211 on one side of the second surface 115 through the second elastic clip 122 and the fourth elastic clip 132 arranged at an angle to the first direction OX. The four elastic clips form a rectangle, the first elastic clip 121 and the third elastic clip are arranged along the diagonal line of the above rectangle, and the second elastic clip 122 and the fourth elastic clip 132 are arranged along the other diagonal line of the above rectangle, thereby further improving the stability of the baffle 113 set in the gap between the two photovoltaic panels 211.

[0062] In one embodiment, the baffle 113 defines a receiving hole 116, and the first end 111 of the elastic clip 110 is movably connected to the inner wall of the receiving hole 116. When the elastic clip 110 is in the second state, the elastic clip 110 is located within the receiving hole 116. Therefore, when the snow guard 100 is installed on or removed from the photovoltaic module 210, the elastic clip 110 does not protrude from the baffle 113 in the second state, thereby preventing the elastic clip 110 from protruding from the baffle 113 and scratching the photovoltaic panel 211. At the same time, the installation and removal of the snow guard 100 are more convenient and quick.

[0063] In another embodiment, when the elastic clip 110 is in the second state, part of the elastic clip 110 is located in the accommodating hole 116 . It is only necessary to ensure that the snow blocking device 100 can pass through the gap between the two photovoltaic panels 211 when the elastic clip 110 is in the second state.

[0064] Preferably, the accommodating hole 116 is a bar-shaped through hole, and the elastic buckle 110 is hook-shaped.

[0065] In one embodiment, the snow guard 100 further includes an elastic abutment 140, one end of which is connected to the baffle 113 and the other end of which abuts against the opposite side of the photovoltaic panel 211. The abutment between the elastic abutment 140 and the opposite side of the photovoltaic panel 211 restricts movement of the snow guard 100 in the thickness direction of the baffle 113, further improving the stability of the snow guard 100. Specifically, during installation of the snow guard 100, the elastic abutment 140 is compressed and placed in the gap between the two photovoltaic panels 211. The elastic abutment 140 is then released, causing the elastic abutment 140 to abut against one of the two opposite side surfaces of the two photovoltaic panels 211, completing installation of the snow guard 100.

[0066] In one embodiment, the elastic abutment 140 includes a connecting portion 141 and an elastic portion 142, wherein the end of the connecting portion 141 facing away from the elastic portion 142 is connected to the baffle 113. The elastic portion 142 is a curved plate, and the side of the curved plate facing away from the baffle 113 abuts against the photovoltaic panel 211. Thus, the elastic portion 142 is mounted to the baffle 113 via the connecting portion 141, so that the connection point between the elastic abutment 140 and the baffle 113 and the elastic deformation point are staggered along the first direction OX, facilitating the installation and use of the elastic abutment 140. At the same time, the side of the curved plate facing away from the baffle 113 abuts against the photovoltaic panel 211, achieving elastic abutment. Preferably, the elastic portion 142 includes an arc-shaped member 144 and a flat member 145 connected to each other. The end of the arc-shaped member 144 facing away from the flat member 145 is connected to the connecting portion 141. The flat member 145 is arranged parallel to the baffle 113. When the elastic abutment member 140 needs to be deformed, the deformation of the arc-shaped member 144 enables the flat member 145 to approach or move away from the baffle 113, thereby realizing the installation and disassembly of the elastic abutment member 140.

[0067] Specifically, the elastic portion 142 is located between two elastic buckles 110 of a group of elastic buckles 110, so that the supporting positions are closer and the supporting stability is improved.

[0068] In one embodiment, the snow blocking device 100 further includes a fastener 150. The baffle 113 defines a first fastening hole 117, and the connecting portion 141 defines a second fastening hole 143. The fastener 150 is inserted through the first fastening hole 117 and the second fastening hole 143. This allows the elastic abutment member 140 to be detachably connected to the baffle 113.

[0069] In one embodiment, the baffle 113 defines a plurality of first fastening holes 117 so that the elastic abutting member 140 can be installed at different positions on the baffle 113 .

[0070] In another embodiment, the connecting portion 141 defines a plurality of second fastening holes 143 , so that the flat plate 145 of the elastic abutting member 140 can change its position relative to the baffle 113 .

[0071] In another embodiment, the baffle 113 defines a plurality of first fastening holes 117 , and the connecting portion 141 defines a plurality of second fastening holes 143 , so that the flat member 145 of the elastic abutting member 140 can change its position relative to the baffle 113 .

[0072] In one embodiment, at least one elastic abutment member 140 is connected to each side of the baffle 113. The two elastic abutment members 140 abut against two opposite sides of the photovoltaic panels 211 on both sides of the baffle 113, respectively. This ensures stable abutment between the two sides of the baffle 113 and the photovoltaic panels 211 on both sides.

[0073] Specifically, the first fastening holes 117 corresponding to the two elastic abutment members 140 are arranged along the first direction OX on the baffle 113, so that the abutment forces on both sides of the baffle 113 can be balanced by connecting the two ends of the baffle 113 with the two connecting parts 141, and the abutment parts are both located in the middle of the baffle 113 for abutting against the side of the photovoltaic panel 211, thereby achieving stable limiting of the baffle 113 in its thickness direction.

[0074] Preferably, each elastic abutment 140 has two second fastening holes 143 arranged along the second direction OY, and the baffle 113 has two corresponding first fastening holes 117. The elastic abutment 140 is connected to the baffle 113 through two fasteners 150, thereby ensuring that the elastic abutment 140 is stably connected to the baffle 113.

[0075] See Figure 1 An embodiment of the present application further provides a photovoltaic assembly 210 , which includes a plurality of photovoltaic panels 211 and a plurality of snow blocking devices 100 .

[0076] At least one snow blocking device 100 is provided between any two adjacent photovoltaic panels 211 along the sliding direction of the accumulated snow.

[0077] During the actual installation and use of the above-mentioned snow blocking device 100, refer to the figure, retract the elastic clip 110 to the second state, and then insert the baffle 113 into the gap between the two adjacent photovoltaic panels 211. When one set of elastic clips 110 passes through the gap between the two photovoltaic panels 211, it returns to the first state from the second state. At this time, the two sets of elastic clips 110 arranged along the first direction OX are both in the first state, and the distance between the second ends 112 of the two sets of elastic clips along the first direction OX is greater than or equal to the thickness of the photovoltaic panel 211. Therefore, the photovoltaic panel 211 can be located between the two sets of elastic clips 110, so that the snow blocking device 100 is clamped in the gap between the two adjacent photovoltaic panels 211. , and at a certain angle to the photovoltaic panel 211. When snow slides off the photovoltaic panel 211, the baffle 113 of the snow guard device 100 can block the snow, preventing it from sliding and damaging the photovoltaic panel 211 or other components or pedestrians. When it is necessary to ensure that the photovoltaic panel 211 is illuminated by light, one set of elastic clips 110 can be retracted from the first state to the second state, thereby releasing the elastic clips 110 from contacting the upper or lower surface of the photovoltaic panel 211, and then removing the snow guard device 100 from the photovoltaic module 210. The elastic clips 110, which can elastically change their retractable state, enable quick installation and removal, improving the installation and maintenance efficiency of the snow guard device 100 on the photovoltaic module 210. The sliding direction of the snow is perpendicular to the thickness direction of the photovoltaic panel 211.
