Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a photovoltaic component cutting skiing device. [Background technology]

[0002] At present, the surface of photovoltaic modules is set to be relatively smooth in order to prevent dust accumulation from affecting power generation, which makes snow slide more easily after snowing. However, snow usually accumulates into piles and slides down under its own weight. If there is no intervention after the snow slides down, it will threaten the temporary buildings on the ground and the lives and properties of passers-by.

[0003] The prior art installs a snow-blocking clamp on the lower side frame of the photovoltaic module, but basically almost every photovoltaic module is installed with a snow-blocking clamp. In order to achieve the maximum snow-blocking effect, it is generally installed in the horizontal middle position of the lower side frame of the photovoltaic module, which cannot play a good snow-blocking role. The frequency of accidents causing property losses due to snow sliding is still relatively high. [Utility Model Content]

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a photovoltaic module cutting ski device to solve the safety risk problem caused by large pieces of snow sliding off the surface of the photovoltaic module.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A photovoltaic module cutting ski device comprises two cutting rib fixing clamps installed at the lateral ends of the lower side frame of the photovoltaic module and at least one cutting rib fixed between the two cutting rib fixing clamps, the cutting rib fixing clamps are provided with fixing columns, the fixing columns are located in the lower extension direction of the photovoltaic module and protrude upward, the ends of the cutting ribs are fixed on the fixing columns, a longitudinal gap is formed between the cutting ribs and the lower side frame of the photovoltaic module, and a height gap is formed with the lower extension plane of the photovoltaic module surface, the cutting ribs cooperate with the cutting rib fixing clamps and the lower side frame of the photovoltaic module to cut the snow sliding down from the surface of the photovoltaic module.

[0007] Preferably, the cutting ribs are steel strands.

[0008] Preferably, a binding portion is provided on the fixing column, and the end of the steel strand is bound and fixed on the binding portion.

[0009] Preferably, a cutting rib fixing fixture connected to the middle portion of the cutting rib is installed at the transverse middle position of the lower side frame of the photovoltaic module.

[0010] Preferably, the cutting rib fixing fixture includes a first fixing block and a second fixing block, the first fixing block is provided with a U-shaped opening, the U-shaped opening has an upper clamping edge, a lower clamping edge and an inner side edge, the upper clamping edge cooperates with the upper side wall of the frame, the inner side edge cooperates with the outer side wall of the frame, the lower clamping edge cooperates with the lower side wall of the frame, and the second fixing block cooperates with the lower clamping edge to clamp the lower side wall of the frame.

[0011] Preferably, the upper clamping edge is connected with a locking screw which is locked and fixed with the upper side wall of the frame.

[0012] Preferably, the second fixing block and the lower clamping edge are provided with fixing holes correspondingly, and the fixing holes are connected with fixing bolts for fixing the first fixing block and the second fixing block together.

[0013] Preferably, the second fixing block is provided with a lower boss which fits with the first fixing block, and the fixing hole is provided at the position of the lower boss.

[0014] Preferably, the first end of the upper clamping edge extends toward the fixing column and is vertically connected to the bottom end of the fixing column, and the connecting position of the lower clamping edge and the inner side edge is connected to a hypotenuse connected to the first end of the upper clamping edge, and the upper clamping edge, the inner side edge and the hypotenuse are combined to form a right triangle structure.

[0015] Preferably, the first fixing block and the second fixing block are made of aluminum alloy profiles.

[0016] The utility model adopts the above technical solution and has the following beneficial effects:

[0017] 1. The cutting rib fixing fixture is fixedly connected to the photovoltaic module frame to fix the photovoltaic module cutting ski device. Since at least one cutting rib is arranged between the two cutting rib fixing fixtures at the two lateral ends of the lower side frame of the photovoltaic module, the cutting rib can cut the accumulated snow, mainly reducing the thickness of the snow block after cutting.

[0018] Among them, the end of the cutting rib is fixed on the fixing column, and the fixing column is located in the lower extension direction of the photovoltaic module and protrudes upward. On the one hand, it is a certain distance away from the lower side frame of the photovoltaic module, which can avoid shadowing the photovoltaic module and affecting the efficiency of the photovoltaic module in absorbing solar energy; on the other hand, it can also be made to have a longitudinal gap between the cutting rib and the lower side frame of the photovoltaic module, and a height gap with the lower extension plane of the photovoltaic module surface, so that the cutting rib and the cutting rib fixing clamp and the lower side frame of the photovoltaic module cooperate to cut the snow sliding down from the surface of the photovoltaic module, so that part of the cut snow blocks slide down from the gap between the cutting rib and the lower side frame of the photovoltaic module, and the other part of the snow slides down from the upper side of the cutting rib, thereby turning the accumulated snow into more small pieces of snow.

[0019] Therefore, compared with the original method of installing a snow-blocking clamp on a photovoltaic module, the range of snow impacting the ground can be reduced, the threat of snow impact to temporary buildings and passers-by's life and property can be reduced, and the safety risk caused by large pieces of snow sliding off the surface of the photovoltaic module can be solved.

[0020] 2. The steel strand is made of multiple steel wires twisted together, and a galvanized layer is added to the surface of the steel wire. It is not only high in strength, but also not easy to rust, has a long service life, and is more effective in cutting snow.

[0021] 3. Tighten the steel strand from the end of the steel strand, and then tie and fix the end of the steel strand to the binding part for easy and quick fixation.

[0022] 4. Since a cutting rib fixing fixture connected to the middle part of the cutting rib is installed in the horizontal middle position of the lower side frame of the photovoltaic module, on the one hand, this middle cutting rib fixing fixture can divide the large snow that slides down from the photovoltaic module in the middle position, and cooperate with the cutting rib to divide the large snow into more small pieces of snow, thereby avoiding large pieces of snow falling at the same time and generating excessive impact force, thereby improving safety; on the other hand, fixing the cutting rib in the middle position and fixing both ends can ensure the reliability of the cutting rib fixation.

[0023] 5. When installing the cutting rib fixing fixture, first clamp the U-shaped opening of the first fixing block with the frame and tighten the locking screw. Then, use the second fixing block and the fixing bolt to fix the first fixing block and the second fixing block on the lower side wall of the frame. The installation process is simple and fast, and the cutting rib fixing fixture can be reliably fixed to the frame to ensure the stability of the connection and avoid the cutting rib fixing fixture being squeezed by snow during use and separated.

[0024] 6. Since the second fixing block is provided with a lower boss, after the lower boss is fitted with the first fixing block, it is ensured that the upper fixing surface of the second fixing block is tightly matched with the upper side of the lower side wall of the frame, so that it is reliably clamped on the lower side wall of the frame.

[0025] 7. Since the upper clamping edge, the inner side edge and the hypotenuse are combined to form a right triangle structure, the structural strength of the first fixing block is effectively improved to avoid deformation.

[0026] 8. Since the first fixing block and the second fixing block are aluminum alloy profiles, the aluminum alloy profiles are extruded, which can realize industrialized production, significantly reduce costs, and have high strength, are not easy to rust, and have a long service life.

[0027] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[Specific implementation method]

[0033] 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.

[0034] 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.

[0035] 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", "longitudinal", "lateral", 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.

[0036] 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.

[0037] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0038] Reference Figures 1 to 3 As shown, the photovoltaic module 100 is rectangular, with rectangular frames all around, and the bottom of the photovoltaic module frame is provided with a lower side wall, and the top is provided with an upper side wall, wherein the lower side wall extends to the inside of the photovoltaic module. Usually, the photovoltaic module is tilted, so the frontmost frame of the photovoltaic module is referred to as the lower side frame. Figure 1 As shown, multiple photovoltaic modules can be arranged in a rectangular array, such as Figure 2 As shown, only a single photovoltaic module may be provided. Generally, the photovoltaic module is installed vertically, that is, it is arranged obliquely in the length direction. For the vertical photovoltaic module, the width direction of the photovoltaic module is the horizontal direction, and the length direction is the vertical direction.

[0039] This embodiment provides a photovoltaic module cutting ski device, comprising two cutting rib fixing fixtures 200 installed at the lateral ends of the lower frame of the photovoltaic module 100 and at least one cutting rib 300 fixed between the two cutting rib fixing fixtures, the cutting rib fixing fixture 200 is provided with a fixing column 211, the fixing column 211 is located in the lower extension direction of the photovoltaic module (i.e., along the oblique extension direction of the photovoltaic module) and protrudes upward, and the end of the cutting rib 300 is fixed on the fixing column 211. Through the above-mentioned cutting rib fixing structure, there is a longitudinal gap between the cutting rib 300 and the lower frame of the photovoltaic module, and there is a height gap with the lower extension plane of the photovoltaic module surface, and the cutting rib 300 cooperates with the cutting rib fixing fixture 200 and the lower frame of the photovoltaic module to cut the snow sliding down from the surface of the photovoltaic module.

[0040] In the above technical solution, the cutting rib fixing fixture is fixedly connected to the photovoltaic module frame to fix the photovoltaic module cutting ski device. Since at least one cutting rib is arranged between the two cutting rib fixing fixtures at the lateral ends of the lower frame of the photovoltaic module, the cutting rib can cut the accumulated snow, mainly to reduce the thickness of the snow block after cutting.

[0041] Among them, the end of the cutting rib is fixed on the fixing column, and the fixing column is located in the lower extension direction of the photovoltaic module and protrudes upward. On the one hand, it is a certain distance away from the lower side frame of the photovoltaic module, which can avoid shadowing the photovoltaic module and affecting the efficiency of the photovoltaic module in absorbing solar energy; on the other hand, it can also be made to have a longitudinal gap between the cutting rib and the lower side frame of the photovoltaic module, and a height gap with the lower extension plane of the photovoltaic module surface, so that the cutting rib and the cutting rib fixing clamp and the lower side frame of the photovoltaic module cooperate to cut the snow sliding down from the surface of the photovoltaic module, so that part of the cut snow blocks slide down from the gap between the cutting rib and the lower side frame of the photovoltaic module, and the other part of the snow slides down from the upper side of the cutting rib, thereby turning the accumulated snow into more small pieces of snow.

[0042] Therefore, compared with the original method of installing a snow-blocking clamp on a photovoltaic module, the range of snow impacting the ground can be reduced, the threat of snow impact to temporary buildings and passers-by's life and property can be reduced, and the safety risk caused by large pieces of snow sliding off the surface of the photovoltaic module can be solved.

[0043] In this embodiment, the cutting rib 300 is a steel strand. The steel strand is composed of a plurality of steel wires twisted together, and a galvanized layer is added to the surface of the steel wire, which is not only high in strength, but also not easy to rust, has a long service life, and has a better effect of cutting snow.

[0044] In order to facilitate the fixing of the steel strand, the fixing column 211 is provided with a binding part 216, and the end of the steel strand is bound and fixed on the binding part. The steel strand is tightened from the end of the steel strand, and then the end of the steel strand is bound and fixed on the binding part, which is convenient, fast and reliable.

[0045] It is understandable that the binding portion 216 may be provided with a limiting groove, and the steel bars are bound and fixed in the limiting groove. A typical structure is as follows: Figure 3 As shown, the binding portion 216 is a T-shaped structure, and of course it can also be an L-shaped structure, or a U-shaped structure, etc. Of course, the steel strand is not limited to binding and fixing. For example, a fixing hole can be provided, and the steel strand passes through the fixing hole. Then a limiting portion can be provided on the other side of the fixing hole, such as crimping a limiting sleeve to fix the end of the steel strand, or a threaded hole can be opened on the side of the fixing hole, and the threaded hole is connected to a locking screw to fix the end of the steel strand.

[0046] It is understandable that the steel strands may also be replaced by steel bars, steel plates, etc.

[0047] like Figure 2As shown, in this embodiment, a cutting rib fixing fixture 200 connected to the middle part of the cutting rib is installed at the horizontal middle position of the lower side frame of the photovoltaic module. On the one hand, this middle cutting rib fixing fixture can split the large snow falling from the photovoltaic module at the middle position, and cooperate with the cutting rib to split the large snow into more small pieces of snow, so as to avoid large pieces of snow falling at the same time and generating excessive impact force, thereby improving safety; on the other hand, fixing the cutting rib at the middle position and fixing at both ends can ensure the reliability of the cutting rib fixation.

[0048] It is understandable that, according to actual needs and conditions, multiple cutting rib fixing clamps 200 can be set along the horizontal direction of the lower side frame of the photovoltaic module to effectively divide large pieces of snow into multiple small pieces of snow, so as to effectively reduce the impact force of the snow sliding down.

[0049] It is understandable that if Figure 1 As shown, when multiple photovoltaic modules can be arranged in a rectangular array, the photovoltaic module cutting ski device only needs to be installed on the lowermost photovoltaic module. Moreover, among two adjacent photovoltaic modules, the cutting rib fixing clamp can be installed only on the end of one of the photovoltaic modules, so that the two photovoltaic modules share one cutting rib fixing clamp.

[0050] like Figure 3 As shown, the cutting rib fixing fixture 200 includes a first fixing block 21 and a second fixing block 22, wherein the first fixing block 21 is provided with a U-shaped opening, and the U-shaped opening has an upper clamping edge 212, a lower clamping edge 214 and an inner side edge 213. The upper clamping edge 212 cooperates with the upper side wall of the frame, the inner side edge 213 cooperates with the outer side wall of the frame, the lower clamping edge 214 cooperates with the lower side wall of the frame, and the second fixing block 22 cooperates with the lower clamping edge to clamp the lower side wall of the frame. Wherein, a threaded hole is provided at the portion where the upper clamping edge cooperates with the upper side wall of the frame, and the threaded hole is connected with a locking screw (not shown in the figure) that is locked and fixed with the upper side wall of the frame. After the U-shaped opening is inserted into the frame, the first fixing block and the frame are initially clamped, at which time the locking screw can be screwed into the threaded hole, and then the locking screw can be tightened so that the bottom of the locking screw abuts against the upper side wall of the frame, so as to improve the fixed connection effect between the first fixing block and the upper side wall of the frame. The second fixing block 22 and the lower clamping edge 214 are provided with fixing holes correspondingly, the fixing holes are located on the outer side of the upper side wall of the frame, and the fixing holes are connected with fixing bolts (not shown in the figure) that fix the first fixing block and the second fixing block together. The fixing bolts are preferably hexagonal bolts, and the outer periphery of the hexagonal bolts is sleeved with gaskets.

[0051] When installing the cutting rib fixing clamp, first clamp the U-shaped opening of the first fixing block with the frame and tighten the locking screw. Then, use the second fixing block and the fixing bolt to make the first fixing block and the second fixing block cooperate and fix on the lower side wall of the frame. The installation process is simple and fast, and the cutting rib fixing clamp can be reliably fixed to the frame to ensure the stability of the connection and avoid the cutting rib fixing clamp being squeezed by snow during use and becoming detached.

[0052] Furthermore, the first end of the upper clamping edge 212 extends all the way toward the fixed column and is vertically connected to the bottom end of the fixed column. The lower clamping edge and the inner side edge are connected at the joint position with a hypotenuse 215 connected to the first end of the upper clamping edge. The upper clamping edge 212, the inner side edge 213 and the hypotenuse 215 are combined to form a right triangle structure, and a cavity of the triangular structure is formed in the middle. Thereby, the structural strength of the first fixed block is effectively improved to avoid deformation. It is understandable that the second end of the upper clamping edge extends beyond the inner side edge by a length equal to or slightly less than the width of the upper side wall of the frame to avoid contact with the surface of the photovoltaic module and damage to the photovoltaic module. Of course, the second end of the lower clamping edge extends beyond the inner side edge by a length greater than the width of the lower side wall of the frame, so that the second fixed block can cooperate with the first fixed block to clamp the lower side wall of the frame.

[0053] like Figure 3 As shown, the second fixing block 22 is provided with an upper fixing surface 221 that matches with the upper side of the lower side wall of the frame, and the second fixing block 22 is provided with a lower boss 222 that fits with the first fixing block, and the fixing hole is provided at the position of the lower boss. The height of the lower boss is equal to the thickness of the lower side wall of the frame, so that after the lower boss fits with the first fixing block, it is ensured that the upper fixing surface 221 is closely matched with the upper side of the lower side wall of the frame, so that it is reliably clamped on the lower side wall of the frame.

[0054] Preferably, the first fixing block and the second fixing block are aluminum alloy profiles. Aluminum alloy profiles are extruded to achieve industrialized production, significantly reduce costs, and have high strength, are not prone to rust, and have a long service life.

[0055] 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.
