Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a snow shielding clamp for photovoltaic components. [Background technology]

[0002] With the continuous development of the photovoltaic market, photovoltaic power stations are installed with more and more components on the south side, and the problem of snowfall and skiing is becoming increasingly prominent. At present, the surface of photovoltaic components is set to be relatively smooth to prevent dust accumulation from affecting power generation, which makes the snow easier to slide after snowing. However, snow usually accumulates into piles and slides down under its own weight. If the snow slides down without intervention, it will threaten the lives and property of temporary buildings on the ground and passers-by.

[0003] The prior art has a snow-blocking clamp installed on the lower side frame of the photovoltaic module. The Chinese invention patent application with reference application publication number CN113179083A discloses a snow-blocking clamp, including a first clamp and a second clamp for clamping with the frame of the photovoltaic module. The first clamp is provided with a U-shaped groove structure for clamping with the upper wall, outer wall and lower wall of the frame, and the U-shaped groove structure extends parallel to the lower wall; the second clamp cooperates with the extended plate of the U-shaped groove structure to clamp the lower wall, and the first clamp is provided with a partition plate for separating the snow on the photovoltaic panel of the photovoltaic module, and the partition plate is arranged on the U-shaped groove structure. The U-shaped groove structure is fixed to the upper wall of the frame by self-tapping screws, and the second clamp cooperates with the first clamp to clamp the lower wall of the frame. Since it has many parts, including the first clamp, the second clamp, the self-tapping screws and the locking piece, the installation is relatively complicated, and the locking bolts connecting the first clamp and the second clamp are fixed under the frame, which makes the construction difficult. [Contents of the utility model]

[0004] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a snow shield clamp for photovoltaic modules, so as to solve the problems of the existing snow shield clamp having many parts and complex installation.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a snow guard clamp for a photovoltaic module, comprising a U-shaped groove fixed to the frame of the photovoltaic module and a snow guard connected to the U-shaped groove, the U-shaped groove comprising an upper clamping edge and a lower clamping edge, the free end of the upper clamping edge is provided with an upper clamping head, and the other end is provided with an upper fastening section, the free end of the lower clamping edge is provided with a lower clamping head, and the other end is provided with a lower fastening section, the snow guard clamp also includes a fastener connecting the upper fastening section and the lower fastening section, and the upper clamp and the lower clamp are cooperated to clamp the upper side wall and the lower side wall of the frame of the photovoltaic module through the fastener.

[0006] Preferably, an upper limit step which cooperates with the outer side wall of the photovoltaic module frame is provided at the connection portion between the upper clamp and the upper fastening section.

[0007] Preferably, a lower limiting step is provided at the junction of the lower clamp and the lower fastening section, and a gap is provided between the lower limiting step and the outer side wall of the photovoltaic component frame.

[0008] Preferably, the head end of the upper clamp is provided with a snap-fitting flange that snaps with the inner edge of the upper side wall of the photovoltaic component frame.

[0009] Preferably, the fastener is a fastening screw, the upper fastening section is provided with a through hole, the lower fastening section is provided with a threaded hole, and the fastening screw passes through the through hole and is connected to the threaded hole.

[0010] Preferably, the thickness of the lower fastening section is greater than the thickness of the upper fastening section.

[0011] Preferably, the fastening screw is a hexagon socket screw.

[0012] Preferably, the U-shaped groove and the snow guard are an integrated structure, and a connecting plate is provided between the lower end of the snow guard and the upper end of the U-shaped groove.

[0013] Preferably, a reinforcing rib is provided between the lower end of the U-shaped groove and the snow guard.

[0014] Preferably, the U-shaped groove and the snow guard are made of high-strength zinc-aluminum-magnesium material.

[0015] The utility model adopts the above technical solution and has the following beneficial effects:

[0016] 1. When the snow on the surface of the photovoltaic module reaches a certain level, it slides down and passes through the snow guard, which separates the snow to avoid unnecessary losses and injuries, thereby reducing damage to nearby objects and people, ensuring personal safety and avoiding property losses, and solving the safety risk problem caused by large pieces of snow sliding off the surface of the photovoltaic module.

[0017] The fastener connects the upper fastening section and the lower fastening section, so that the upper clamp and the lower clamp cooperate to clamp the upper side wall and the lower side wall of the photovoltaic module frame, thereby meeting the requirements of fitting the photovoltaic module frame, increasing the clamping force, not easy to fall off, and having a higher degree of safety. Compared with the prior art, it is only necessary to engage the U-shaped groove with the frame and then fasten it with the fastener, which has relatively fewer parts and is more convenient to install.

[0018] In addition, the snow guard clamp can be fixed on the long side of the component, and can also be fixed on the short side of the component. Both the long side and the short side can be fixed, and it has strong applicability.

[0019] 2. When installing the snow-blocking clamp, after the upper limit step cooperates with the outer wall limit of the photovoltaic module frame, the relative position between the U-shaped groove and the frame is positioned, which is convenient for subsequent fasteners to tighten. Since the distance between the upper clamp and the lower clamp in the free state is greater than the distance between the upper side wall and the lower side wall of the frame, and there is a gap between the lower limit step and the outer wall of the photovoltaic module frame, the lower clamp can move upward. Therefore, when the fastener is tightened, the distance between the upper fastening section and the lower fastening section becomes smaller, and the upper clamp and the lower clamp are driven to reduce the distance at the same time, so that the upper clamp and the lower clamp can finally cooperate to clamp the upper side wall and the lower side wall of the photovoltaic module frame.

[0020] 3. The buckled flange can increase the reliability of the fixation with the frame, greatly increase the clamping force of the snow blocking clamp on the frame, and increase the snow blocking ability. In addition, before the fasteners are tightened, the buckled flange can prevent it from falling off the frame.

[0021] 4. The fasteners are fastening screws, which can be fastened with a single screw. A through hole is provided on the upper fastening section, and a threaded hole is provided on the lower fastening section. The fastening screw passes through the through hole from top to bottom and is connected with the threaded hole. It can be fastened above the frame. There is a large space, and the screw can be tightened with one hand, so it is convenient to fix, and the construction is simple and convenient.

[0022] 5. The U-shaped groove and the snow guard are an integrated structure, connected as a whole by a connecting plate to form a whole snow guard, which is usually made of aluminum alloy profiles, such as high-strength zinc-aluminum-magnesium materials. While ensuring anti-corrosion performance, it is stronger and has lower cost. And the connecting plate keeps a certain distance between the snow guard and the frame, so as to avoid blocking the photovoltaic modules.

[0023] 6. Reinforcing ribs may also be provided between the lower end of the U-shaped groove and the snow guard to ensure the overall structural strength and prevent the snow guard from falling off the frame of the photovoltaic module due to insufficient strength.

[0024] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[Specific implementation method]

[0032] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0033] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0034] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the following words indicating orientation or positional relationship, such as "upper", "lower", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0035] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] Referring to the prior art, the photovoltaic module is rectangular, and each photovoltaic module is surrounded by a rectangular frame. In addition, in a photovoltaic system, multiple photovoltaic modules can be arranged in a rectangular array, or only a single photovoltaic module can be set, and the photovoltaic module is installed on a photovoltaic bracket. Since the photovoltaic module is tilted, the snow slides down from top to bottom, so the snow blocking clamp is installed on the lower side frame of the photovoltaic module.

[0037] In order to solve the problem that the existing snow guard fixture has many parts and complex installation. Figures 1 to 5 As shown, this embodiment provides a snow blocking fixture for photovoltaic modules, which is installed on the frame of the photovoltaic module, including a snow blocking block 1 and a fastener, wherein the frame 100 has an upper side wall 101, an outer side wall 102 and a lower side wall 103, and the snow blocking block 1 includes a U-shaped groove 11, a snow blocking board 12 connected to the U-shaped groove 11, and the snow blocking board 12 extends upward. The fastener fixes the snow blocking block 1 to the photovoltaic module frame 100, and the snow blocking board 12 is located on the sliding path of the snow. When the snow on the photovoltaic module reaches a certain level, it slides down and passes through the snow blocking board, and the snow is divided by the snow blocking board to avoid unnecessary losses and injuries, thereby reducing damage to nearby objects and people, ensuring personal safety and avoiding property losses, and solving the safety risk problem caused by large pieces of snow sliding on the surface of the photovoltaic module.

[0038] In this embodiment, the U-shaped groove 11 includes an upper clamping edge 111, a lower clamping edge 112 and a connecting edge 113, thereby forming a U-shaped groove structure. The snow guard 12 extends upward and is perpendicular to the upper clamping edge 111. Of course, it can also have a certain angle. The free end of the upper clamping edge 111 is provided with an upper clamping head 1111, and the other end is provided with an upper fastening section 1112. The free end of the lower clamping edge 112 is provided with a lower clamping head 1121, and the other end is provided with a lower fastening section 1122. The fastener connects the upper fastening section 1112 and the lower fastening section 1122, and the upper clamping head 1111 and the lower clamping head 1121 cooperate to clamp the upper side wall 101 and the lower side wall 103 of the photovoltaic module frame, so as to meet the requirements of fitting the photovoltaic module frame, increase the clamping force, not easy to fall off, and have a higher degree of safety. In addition, compared with the prior art, it is only necessary to engage the U-shaped groove with the frame, and then fasten it with the fastener, so there are relatively fewer parts and it is more convenient to install.

[0039] Among them, before the fastener is tightened, the distance between the upper clamp 1111 and the lower clamp 1121 in the free state is greater than the distance between the upper side wall 101 and the lower side wall 103 of the frame, so that when the snow guard clamp is installed, the upper clamp 1111 and the lower clamp 1121 cooperate with the frame.

[0040] Furthermore, an upper limit step 1113 is provided at the joint of the upper clamp 1111 and the upper fastening section 1112, which is limited to the outer wall of the photovoltaic module frame. A lower limit step 1123 is provided at the joint of the lower clamp 1121 and the lower fastening section 1122, and even after the fastener is fastened, there is a gap between the lower limit step 1123 and the outer wall 102 of the photovoltaic module frame. When installing the snow guard clamp, the upper limit step 1113 is limited to the outer wall of the photovoltaic module frame, and the relative position between the U-shaped groove and the frame is positioned, which is convenient for subsequent fastening of the fastener. Since the distance between the upper clamp 1111 and the lower clamp 1121 in the free state is greater than the distance between the upper side wall 101 and the lower side wall 103 of the frame, and there is a gap between the lower limit step and the outer side wall of the photovoltaic module frame, the lower clamp 1121 can move upward. Therefore, when the fastener is tightened, the distance between the upper fastening section and the lower fastening section becomes smaller, and drives the upper clamp 1111 and the lower clamp 1121 to reduce the distance at the same time, so that the upper clamp and the lower clamp finally cooperate to clamp the upper side wall 101 and the lower side wall 103 of the photovoltaic module frame. At the same time, after the upper limit step and the lower limit step cooperate with the outer side wall of the photovoltaic module frame, the relative position between the U-shaped groove and the frame is positioned.

[0041] Furthermore, the head end of the upper clamp 1111 is provided with a buckling flange 1115 buckled with the inner edge of the upper side wall of the photovoltaic module frame. The inner edge of the upper side wall of the photovoltaic module frame has a curvature, so the buckling flange 1115 also has a curvature. The buckling flange can increase the reliability of fixing with the frame, greatly increase the clamping force of the snow blocking clamp on the frame, and increase the snow blocking ability. Moreover, before the fastener is tightened, the buckling flange has the function of preventing it from falling off the frame.

[0042] In order to facilitate quick fixing, the fastener can be a fastening screw 2, wherein the upper fastening section is provided with a through hole 1114, the lower fastening section is provided with a threaded hole 1124, and the fastening screw 2 passes through the through hole 1114 and is connected to the threaded hole 1124. The fastening screw is a certain distance away from the connecting edge 113 to ensure that when the fastening screw is tightened, the upper clamping edge 111 and the lower clamping edge 112 are relatively deformed and the spacing becomes smaller. A single screw can be used for fastening, and the fastening screw passes through the through hole from top to bottom and is connected to the threaded hole. It can be fastened above the frame, and the space is large. Tightening the screw can be operated with one hand, so it is convenient to fix, and the construction is simple and convenient. Of course, bolts can also be used as fasteners.

[0043] Since the threaded hole is opened on the lower fastening section, in order to ensure that the threaded hole has sufficient depth to cooperate with the fastening screw plate to prevent the thread from slipping, the thickness of the lower fastening section 1122 is greater than the thickness of the upper fastening section 1112, and the specific thickness can be designed as needed. Preferably, the fastening screw is a hexagon socket screw, which is convenient for tightening from the top.

[0044] Preferably, the U-shaped groove 11 and the snow guard 12 are an integrated structure, and a connecting plate 13 is provided between the lower end of the snow guard and the upper end of the U-shaped groove. That is, the entire snow guard is an integrated structure, usually made of aluminum alloy profiles, such as high-strength zinc-aluminum-magnesium materials. While ensuring anti-corrosion performance, the strength is greater and the cost is lower. In addition, the connecting plate extends to the snow guard along the extension direction of the upper clamping edge, and the snow guard is kept at a certain distance from the frame through the connecting plate, thereby avoiding blocking the photovoltaic module.

[0045] Furthermore, reinforcing ribs may be provided between the lower end of the U-shaped groove and the snow guard, thereby ensuring the overall structural strength and preventing the snow guard from falling off the photovoltaic module frame due to insufficient strength.

[0046] It is understandable that the above-mentioned snow blocking clamp can be fixed on the long side of the component, or on the short side of the component, and both the long side and the short side can be fixed, which has strong applicability. Of course, the snow blocking clamp can also be applied to the component without a frame, and can be fixed on the edge of the component.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
