Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a buffer snow blocking device. [Background technology]

[0002] With the continuous development of the photovoltaic market, more and more components are protruding from the south side of the installation of household photovoltaic power stations, and the problems of snowfall and skiing are 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 installs a snow-blocking clamp on the lower side frame of the photovoltaic module, or adds a snow-blocking net to prevent the snow on the photovoltaic module from sliding down in an instant in winter, and injuring pedestrians under the house or damaging other objects. The Chinese invention patent application with reference application publication number CN113179083A includes 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 provided 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 the snow-blocking clamp may be washed away when the snow falls, the damage or loss caused by the snow cannot be reduced. In addition, snow guards installed on the frames of photovoltaic modules may tear the modules, affect power generation efficiency, and cause economic losses. [Contents of the utility model]

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a buffer snow blocking device installed on a photovoltaic bracket to solve the problem that the snow blocking clamp may be washed away together with the falling snow, thereby avoiding injuries and losses caused by the sliding of snow.

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

[0006] A buffer snow-blocking device installed on a photovoltaic bracket comprises a cantilever beam connected to the photovoltaic bracket and a buffer snow-blocking assembly installed on the cantilevered end of the cantilever beam, wherein the buffer snow-blocking assembly is located on the front side of the lower side frame of the photovoltaic assembly, and the buffer snow-blocking assembly comprises an upper buffer snow-blocking member and a lower skiing member hinged together, wherein the upper buffer snow-blocking member is connected with an elastic member, and the accumulated snow slides along the surface of the photovoltaic assembly and pushes the upper buffer snow-blocking member to flip outward, and the elastic member is used to prevent the upper buffer snow-blocking member from flipping outward and provide a buffering force, and the elastic member drives the upper buffer snow-blocking member to flip inward and reset after the accumulated snow on the upper buffer snow-blocking member slides down, and the lower skiing member is used to guide the accumulated snow buffered by the upper buffer snow-blocking member to slide downward.

[0007] Preferably, the upper side of the upper buffer snow guard is close to the surface of the photovoltaic module to form a ski gap with the surface of the photovoltaic module; the lower ski is provided with a lower ski surface connected to the lower side of the upper buffer snow guard, and the lower side of the lower ski surface extends below the photovoltaic module, so that the skis buffered by the upper buffer snow guard can slide down the lower ski surface to below the photovoltaic module.

[0008] Preferably, the upper buffer snow guard is arc-shaped, with one end of the arc located in front of the lower frame of the photovoltaic module and the other end extending upward from the lower frame of the photovoltaic module; and / or, the lower snow guard is arc-shaped, with one end of the arc connected to the lower side of the upper buffer snow guard and the other end extending backward to directly below the photovoltaic module.

[0009] Preferably, the lower ski piece and the upper buffer snow shield are provided with lugs, and the lugs are connected with pins.

[0010] Preferably, the elastic member is a torsion spring mounted on a pin shaft, and one end leg of the torsion spring is connected to the lower ski member, and the other end leg is connected to the upper buffer snow guard member.

[0011] Preferably, both lateral ends of the lower side of the lower ski are connected with fixing ears, and the fixing ears are fixed to the front end of the cantilever beam.

[0012] Preferably, the upper buffer snow guard and the lower ski member are both sheet metal members; and / or the upper buffer snow guard and the lower ski member are made of zinc-aluminum-magnesium materials.

[0013] Preferably, the photovoltaic support includes a crossbeam, and the rear end of the cantilever beam is connected to the crossbeam via a fixing clamp.

[0014] Preferably, the fixing fixture comprises a U-shaped card, the U-shaped card is plugged into the rear end of the cantilever beam and connected to a first fastener, and a second fastener is provided between the U-shaped card and the crossbeam.

[0015] Preferably, the first fastener and the second fastener are both fixing bolts.

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

[0017] 1. The buffer snow guard assembly is located on the front side of the lower frame of the photovoltaic module. When the snow on the photovoltaic module reaches a certain level, it slides downward and passes through the buffer snow guard assembly, pushing the upper buffer snow guard to flip outward. During this process, the elastic member blocks the upper buffer snow guard from flipping outward and provides buffering force. Finally, the snow buffered by the upper buffer snow guard slides downward along the lower ski member.

[0018] The lower ski piece is used to guide the snow that has been buffered by the upper buffer snow guard to slide down. In order to prevent the sliding snow from falling in front of the roof, the lower ski piece can be designed accordingly to make the sliding snow fall directly below the photovoltaic module. Since the entire photovoltaic bracket is installed on the roof, the snow that slides down from the lower ski surface will fall on the roof. In this way, the buffer snow guard component changes the direction of the snow falling, changing the direction that originally slid down directly from the surface of the photovoltaic module to the ground to sliding from the surface of the photovoltaic module to the roof, greatly reducing the falling height of the snow and changing the falling position, which is conducive to avoiding the incident of snow sliding from the roof and hitting the ground.

[0019] When all the accumulated snow has slid off, there is no impact force of the accumulated snow on the upper buffer snow blocking member, and the upper buffer snow blocking member returns to its original shape with the help of the elastic member.

[0020] The buffer snow guard assembly is installed on the cantilever beam and will not affect the photovoltaic assembly. Compared with the prior art of installing snow guard clamps, the problem that the snow guard clamps may be washed away when the snow falls is solved, thus avoiding the damage and loss caused by the sliding of the snow.

[0021] 2. The upper side of the upper buffer snow guard is close to the surface of the photovoltaic module to form a ski gap between the surface of the photovoltaic module. When the accumulated snow slides along the surface of the photovoltaic module, it passes through the ski gap and pushes the upper buffer snow guard to flip outward, thereby increasing the ski gap. Then, a larger horizontal distance is formed between the lower side frame of the photovoltaic module and the upper buffer snow guard. During this process, the elastic member prevents the upper buffer snow guard from flipping outward and provides buffering force.

[0022] Since the lower ski piece is provided with a lower ski surface connected to the lower side of the upper buffer snow guard, the lower side of the lower ski surface extends below the photovoltaic module, so that the skis buffered by the upper buffer snow guard slide down the lower ski surface to below the photovoltaic module, changing the direction of sliding directly downward from the surface of the photovoltaic module to the direction of sliding from the surface of the photovoltaic module to the roof.

[0023] 3. The upper buffer snow guard and the lower ski are both arc-shaped. In the natural state, the upper buffer snow guard and the lower ski are roughly semicircular. After the accumulated snow enters the upper buffer snow guard, it naturally pushes the upper buffer snow guard to flip outward, and the arc-shaped structure of the lower ski is conducive to the sliding of the accumulated snow and changing the sliding direction.

[0024] 4. The lower ski and the upper buffer snow guard are provided with lugs, which are connected to the pin shaft through the lugs, and the elastic member is a torsion spring installed on the pin shaft, which not only facilitates the hinge connection of the lower ski and the upper buffer snow guard, but also installs the torsion spring at the same time.

[0025] 5. The lower ski piece is fixed to the side of the front end of the cantilever beam through the fixing ears at both ends of the lower side, so that the buffer snow guard assembly can be installed on the front end of the cantilever beam.

[0026] 6. The upper buffer snow guard and the lower ski part are both sheet metal parts, which have the advantages of light weight, high strength, low cost, and good mass production performance. In addition, the upper buffer snow guard and the lower ski part are made of zinc-aluminum-magnesium materials, which have the advantages of high strength, light weight, corrosion resistance, and low mass production cost.

[0027] 7. Compared with fixing with the longitudinal beam, since the cross beam is closer to the photovoltaic module, after fixing the cantilever beam with a fixing clamp, it is convenient to install the buffer snow guard assembly at the front end of the cantilever beam. After installation, the buffer snow guard assembly is located just in front of the lower side frame of the photovoltaic module, which is the most conducive position for buffering snow. The fixing clamp adopts a U-shaped card and cooperates with fixing bolts, which is convenient for fixing with the cross beam and the rear end of the cantilever beam at the same time.

[0028] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[Specific implementation method]

[0037] 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.

[0038] 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.

[0039] 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 words "upper", "lower", "front", "back", etc., which indicate the orientation or position relationship, are based on the orientation or position 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.

[0040] 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.

[0041] 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.

[0042] Referring to the prior art, photovoltaic modules are 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. For household photovoltaic systems, photovoltaic modules are installed on photovoltaic brackets, and photovoltaic brackets are installed on the roof. Usually, the lower side of the photovoltaic module has a cantilevered part that exceeds the front side of the photovoltaic bracket. Here, the horizontal projection of the lower side of the photovoltaic module is still on the roof.

[0043] Although the horizontal projection of the lower side frame of the photovoltaic module is located on the roof, the photovoltaic module is tilted because it is close to the front edge of the roof. The accumulated snow slides diagonally from top to bottom and easily rushes to the front of the roof. Therefore, the prior art is to install a snow blocking clamp on the lower (the lowest overall tilt) side frame of the photovoltaic module to block and divide the accumulated snow.

[0044] In order to solve the problem that the falling snow may wash away the snow guard clamp and tear the components, avoid the damage and loss caused by the falling snow. Figures 1 to 6 As shown, this embodiment provides a buffer snow shield device 1 installed on a photovoltaic support, including a cantilever beam 14 connected to the photovoltaic support 200 and a buffer snow shield assembly installed on the cantilever beam. The cantilever beam 14 extends below the cantilevered portion of the photovoltaic assembly along the tilting direction of the photovoltaic assembly 100, and the buffer snow shield assembly is installed at its cantilevered end, that is, the front end, which also makes the buffer snow shield assembly located at the front side of the lower side frame of the photovoltaic assembly. The buffer snow shield assembly includes an upper buffer snow shield member 11 and a lower ski member 12, the lower side of the upper buffer snow shield member 11 is hinged to the lower ski member 12, and the upper buffer snow shield member 11 is connected to an elastic member. After the accumulated snow 300 slides along the surface of the photovoltaic module 100, it pushes the upper buffer snow guard 11 to flip outward. The elastic member is used to prevent the upper buffer snow guard from flipping outward and provide a buffering force. After the accumulated snow on the upper buffer snow guard slides down, the elastic member drives the upper buffer snow guard 11 to flip inward and reset. The lower ski member 12 is used to guide the accumulated snow that has been buffered by the upper buffer snow guard 11 to slide downward.

[0045] In the above technical solution, the buffer snow guard assembly is located on the front side of the lower side frame of the photovoltaic assembly. When the snow accumulation on the photovoltaic assembly reaches a certain level, it slides downward and passes through the buffer snow guard assembly, pushing the upper buffer snow guard to flip outward. During this process, the elastic member blocks the upper buffer snow guard from flipping outward and provides buffering force. Finally, the accumulated snow buffered by the upper buffer snow guard slides downward along the lower ski member.

[0046] The lower ski piece is used to guide the snow that has been buffered by the upper buffer snow guard to slide down. In order to prevent the sliding snow from falling in front of the roof, the lower ski piece can be designed accordingly to make the sliding snow fall directly below the photovoltaic module. Since the entire photovoltaic bracket is installed on the roof, the snow that slides down from the lower ski surface will fall on the roof. In this way, the buffer snow guard component changes the direction of the snow falling, changing the direction that originally slid down directly from the surface of the photovoltaic module to the ground to sliding from the surface of the photovoltaic module to the roof, greatly reducing the falling height of the snow and changing the falling position, which is conducive to avoiding the incident of snow sliding from the roof and hitting the ground.

[0047] When all the accumulated snow has slid off, there is no impact force of the accumulated snow on the upper buffer snow blocking member, and the upper buffer snow blocking member returns to its original shape with the help of the elastic member.

[0048] The buffer snow guard assembly is installed on the cantilever beam and will not affect the photovoltaic assembly. Compared with the prior art of installing snow guard clamps, the problem that the snow guard clamps may be washed away when the snow falls is solved, thus avoiding the damage and loss caused by the sliding of the snow.

[0049] like Figure 3 As shown, in the natural state, the upper side of the upper buffer snow guard 11 is close to the surface of the photovoltaic module to form a ski gap with the surface of the photovoltaic module. When the accumulated snow slides along the surface of the photovoltaic module, it passes through the ski gap and pushes the upper buffer snow guard to flip outward, increasing the ski gap, and then a larger horizontal distance is formed between the lower side frame of the photovoltaic module and the upper buffer snow guard. In this process, the elastic member prevents the upper buffer snow guard from flipping outward and provides a buffering force. Figure 3 and Figure 6 As shown, the lower ski 12 is provided with a lower ski surface connected to the lower side of the upper buffer snow guard, and the lower side of the lower ski surface extends below the photovoltaic module, so that the ski after being buffered by the upper buffer snow guard slides down the lower ski surface to below the photovoltaic module. The original direction of sliding down diagonally from the surface of the photovoltaic module to the ground is changed to sliding from the surface of the photovoltaic module to the roof.

[0050] Specifically, the upper snow buffer 11 is arc-shaped, and one end of the arc is located in front of the lower frame of the photovoltaic module, and the other end is located above the lower frame of the photovoltaic module. The lower ski 12 is arc-shaped, and one end of the arc is connected to the lower side of the upper snow buffer, and the other end extends to the bottom of the photovoltaic module. In a natural state, the upper snow buffer and the lower ski are roughly semicircular. After the accumulated snow enters the upper snow buffer, it naturally pushes the upper snow buffer to flip outward, and the arc-shaped structure of the lower ski is conducive to the sliding of the accumulated snow and changing the sliding direction.

[0051] Furthermore, the lower ski 11 and the upper buffer snow guard 12 are provided with lugs, and the lugs are connected to pins. The lower ski and the upper buffer snow guard are provided with lugs at both lateral ends, and a pin is connected to each of the lateral ends. Preferably, the elastic member is a torsion spring installed on the pin. It is not only convenient to hinge the lower ski and the upper buffer snow guard, but also to install a torsion spring at the same time. One end of the torsion spring is connected to the lower ski, and the other end is connected to the upper buffer snow guard, which has a tendency to make the upper buffer snow guard flip inward. Of course, the elastic member can also be a tension spring, and the two ends of the tension spring are respectively connected to the lower ski and the upper buffer snow guard, and the spring is stretched when the upper buffer snow guard flips outward.

[0052] Furthermore, an angle limit block may be provided on the lower ski part, so that after the upper buffer snow guard part is turned outward to a certain angle, it cannot be turned further, for example Figure 6 Status shown.

[0053] In addition, the lower ends of the lower ski 12 are connected with fixing ears 13, and the fixing ears 13 are fixed to the side of the front end of the cantilever beam. The fixing ears can be integrally provided with the lower ski and can be fixed to the cantilever beam by screws, so that the buffer snow guard assembly can be installed on the front end of the cantilever beam.

[0054] Preferably, the upper buffer snow guard 11 and the lower ski 12 are both sheet metal parts. They have the advantages of light weight, high strength, low cost, and good mass production performance. In addition, the upper buffer snow guard 11 and the lower ski 12 are made of zinc-aluminum-magnesium material. They have the advantages of high strength, light weight, corrosion resistance, and low mass production cost. Of course, they can also be replaced with stainless steel or other materials.

[0055] Referring to the prior art, the photovoltaic support 200 includes a longitudinal beam 21 and a transverse beam 22 that are vertically cross-fixed, and a column 23 that supports the longitudinal beam. A hinge seat 24 is fixed on the longitudinal beam, and the column is hinged to the hinge seat.

[0056] In order to install the cantilever beam on the photovoltaic support, Figure 4As shown, the rear end of the cantilever beam 14 is connected to the crossbeam 22 through a fixing fixture. The cantilever beam is connected to the crossbeam at the lowest position of the photovoltaic support, so as to achieve the purpose of making the buffer snow blocking assembly located at the front side of the lower side frame of the photovoltaic assembly. Specifically, the fixing fixture includes a U-shaped card 15, the U-shaped card 15 is plugged with the rear end of the cantilever beam and connected to the first fastener 17, and a second fastener 16 is provided between the U-shaped card and the crossbeam. The first fastener and the second fastener are both fixing bolts, wherein the first fastener longitudinally passes through the bottom wall and the crossbeam of the U-shaped card and is fixed, and the second fastener vertically passes through the two side walls and the cantilever beam of the U-shaped card and is fixed. Compared with fixing with the longitudinal beam, since the crossbeam is closer to the photovoltaic assembly, after being fixed by the above-mentioned fixing fixture, it is convenient for the buffer snow blocking assembly to be installed on the cantilever end of the cantilever beam, and it is just located on the front side of the lower side frame of the photovoltaic assembly, which is the most conducive position for buffering snow blocking, and the fixing fixture adopts a U-shaped card, which is convenient for fixing with the crossbeam and the rear end of the cantilever beam at the same time.

[0057] It can be understood that the above-mentioned buffer snow-blocking assembly extends integrally on the front side of the lower frame of the photovoltaic assembly, and is connected to the cantilever beam at both lateral ends, so as to buffer and guide the accumulated snow sliding down in the entire lateral direction.

[0058] 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.
