Abstract
Description
[Technical Field]
[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to a photovoltaic support snow net device. [Background Technology]
[0002] Currently, photovoltaic modules have relatively smooth surfaces to prevent dust accumulation from affecting power generation, which makes it easier for snow to slide off after snowfall. However, snow often accumulates and slides off under its own weight. If left unchecked, this sliding snow can threaten the lives and property of temporary structures and pedestrians.
[0003] Currently, snow-blocking devices are typically installed to address the safety risks posed by large chunks of snow sliding off the surface of photovoltaic modules. Existing technologies also disclose solutions involving installing snow-blocking clamps or snow nets on the downward-facing side of the photovoltaic modules.
[0004] Inadequacies of existing anti-skid devices:
[0005] 1. Poor adaptability: Most anti-skid devices on the market, such as clamps, adopt a fixed design, which cannot adapt to photovoltaic modules with different frame heights, thus limiting their application range.
[0006] 2. Limited effectiveness: Some snow-proof devices can only provide simple blocking and cannot effectively slow down the speed of snow slid down, nor can they break up the snow into smaller pieces to reduce the impact.
[0007] 3. Safety hazards: During the snow melting process, large areas of snow can slide down from high places, which can easily cause serious damage to people and property. [Utility Model Content]
[0008] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a snow net device for photovoltaic brackets to solve the safety risk caused by large snow falling from the surface of photovoltaic modules.
[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0010] A snow-blocking net device for a photovoltaic support includes a snow-blocking base installed vertically below a photovoltaic array and a snow-blocking net connected to the snow-blocking base. The snow-blocking net is higher than the lower vertical edge of the photovoltaic array. The snow-blocking base is provided with a first hook connected to the snow-blocking net, and the snow-blocking base is connected with a first fastener to fix the snow-blocking net.
[0011] Preferably, the snow-blocking base includes a vertically arranged vertical plate, and the first hook is located on the upper part of the snow-facing side of the vertical plate.
[0012] Preferably, the snow-facing side of the vertical plate is provided with a lug that bends vertically to the side below the first hook, and the lug abuts against the snow net and is connected to the first fastener.
[0013] Preferably, the snow-facing side of the vertical plate extends obliquely; and / or, the first fastener is a bolt, and the ear plate is provided with a fixing hole for connection with the bolt.
[0014] Preferably, the upper middle part of the snow-facing side of the vertical board is provided with a shoulder that is connected to the snow-blocking net; and / or, the lower middle part of the snow-facing side of the vertical board is provided with a waist that is connected to the snow-blocking net.
[0015] Preferably, the snow net has a first bend on its upper side, which is connected to a first hook; and / or, the snow net has a second bend on its lower side, which is connected to a shoulder.
[0016] Preferably, the snow net has a middle bend in the middle, which abuts against the ear plate; and / or, the snow net has a lower bend on the lower side of the second bend, which abuts against the waist.
[0017] Preferably, the snow-blocking base includes a base plate vertically connected to the bottom of the vertical plate, and the base plate is connected to a second fastener that is fixed to the longitudinal beam.
[0018] Preferably, the snow-blocking base is installed on the longitudinal beam of the photovoltaic support, the longitudinal beam is U-shaped steel or C-shaped steel and the opening faces upward, the second fastener is a press-fit bolt, and the base plate is located on the lower side of the longitudinal beam and fixed to the bottom wall of the longitudinal beam by the press-fit bolt; or, the longitudinal beam is U-shaped steel or C-shaped steel and the opening faces sideways, the second fastener is a bolt, and the base plate is located on the upper side of the longitudinal beam and fixed to the side wall of the longitudinal beam by the bolt.
[0019] Preferably, the vertical plate is provided with a second hook, and while the bottom plate is fixed to the bottom wall of the longitudinal beam by a press-fit bolt, the second hook is fastened and fixed to the opening of the U-steel or C-steel.
[0020] The present invention adopts the above technical solution and has the following beneficial effects:
[0021] 1. When skiers slide down the surface of photovoltaic modules, the snow net effectively prevents large pieces of skis from falling. Furthermore, the snow net cuts the skis, causing them to fall in loose or small pieces. This reduces the impact area on the ground, minimizing the threat to temporary structures and pedestrians, and resolving the safety risks posed by large pieces of skis falling from the surface of photovoltaic modules.
[0022] The snow netting is positioned above the lower longitudinal edge of the photovoltaic array, facing the skiers. It not only acts as a barrier but also effectively slows down the speed at which snow slides down the slope. Furthermore, the mesh structure helps to break up the snow into smaller pieces to reduce impact.
[0023] The snow-blocking base can be fixed to photovoltaic brackets or other basic structures. Unlike existing clamps that are fixed to the photovoltaic module frame, it does not need to consider the changes in the height of different photovoltaic module frames, and has a wide range of applications.
[0024] In addition, the snow-blocking base is equipped with a first hook for connecting to the snow-blocking net, and the snow-blocking base is connected to a first fastener for fixing the snow-blocking net. The first hook facilitates quick connection of the snow-blocking net to the snow-blocking base, and the first fastener further increases the reliability of the snow-blocking net.
[0025] 2. The first hook is located on the upper part of the snow-facing side of the vertical plate. The vertical plate has a side-bent ear plate below the first hook, which is connected to the first fastener. When installing the snow net, first connect the snow net to the snow net base via the first hook, and then connect the first fastener for quick and easy fixing. Because the vertical plate is perpendicular to the snow net, a side-bent ear plate is provided for connection to the first fastener.
[0026] 3. The snow-facing side of the vertical board extends diagonally, with a first hook, shoulder section, and waist section arranged sequentially from top to bottom. Correspondingly, the snow net has a multi-segmented bending structure from top to bottom. The upper side of the snow net has a first bend that connects to the first hook, and the lower side has a second bend that connects to the shoulder section. This multi-segmented bending structure connects the mesh of the snow net to the first hook and shoulder section on the snow-facing side of the vertical board, creating multiple fixing points along the height of the snow net. This provides multi-directional support for the snow net, preventing damage from skier impacts.
[0027] 4. The snow net has a middle bend in the middle, which abuts against the ear plate. The first fastener is a bolt. The ear plate has fixing holes for connecting to the bolt. In this way, the middle bend and the ear plate form a layered structure, which makes it easy for the bolt to fix the two together.
[0028] 5. The snow net has a lower bend on the underside of the second bend, which abuts against the waist, thus adding another layer of support in the height direction and improving the overall support strength.
[0029] 6. To facilitate the fixing of the snow-blocking base, the snow-blocking base is installed on the longitudinal beam of the photovoltaic support, thereby setting multiple snow-blocking bases along the horizontal direction so that the snow-blocking net covers the entire horizontal direction, and the snow-blocking net is reliably fixed by multiple points to prevent it from falling off.
[0030] 7. When the longitudinal beam is made of U-steel or C-steel and the opening faces upward, the second fastener is a press-fit bolt. The base plate is located on the underside of the longitudinal beam and is fixed to the bottom wall of the longitudinal beam by the press-fit bolt. In addition, a second hook is provided on the vertical plate. While the base plate is fixed to the bottom wall of the longitudinal beam by the press-fit bolt, the second hook is engaged and fixed with the opening of the U-steel or C-steel. Therefore, the fixation is reliable and it is not easy to loosen or fall off.
[0031] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

[0040] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0041] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.
[0042] The terminology used in this invention is for the purpose of describing specific embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "inner," "outer," "longitudinal," and "lateral," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0044] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0045] refer to Figures 1 to 4 In a photovoltaic system 1, several photovoltaic modules 100 can be arranged in a rectangular array or a single photovoltaic module can be installed. However, from an economic point of view, it is usually set up as a photovoltaic array. This embodiment is also described with the case of setting up a photovoltaic array. The photovoltaic support includes a longitudinal beam 11 and a transverse beam 12, on which the photovoltaic array is installed. The photovoltaic array is set at an angle, with the tilt direction set as longitudinal and its vertical direction as transverse. Taking one type of photovoltaic support snow net device as an example, it includes a snow-blocking base 3 installed on the longitudinal beam 11 of the photovoltaic support and a snow-blocking net 2 connected to the snow-blocking base 3. The snow-blocking net 2 is higher than the lower longitudinal edge of the photovoltaic array. The snow-blocking base 3 is provided with a first hook 33 connected to the snow-blocking net 2. The snow-blocking base 3 is connected with a first fastener 38 to fix the snow-blocking net 2.
[0046] When skiers slide down the surface of photovoltaic modules, the snow netting effectively prevents large chunks of skis from falling. Furthermore, the snow netting cuts the skids, causing them to fall in loose or small pieces. This reduces the impact area on the ground, minimizing the threat to temporary structures and pedestrians, and addressing the safety risks posed by large skid chunks on the surface of photovoltaic modules.
[0047] The snow netting is positioned above the lower longitudinal edge of the photovoltaic array, facing the skiers. It not only acts as a barrier but also effectively slows down the speed at which snow slides down the slope. Furthermore, the mesh structure helps to break up the snow into smaller pieces to reduce impact.
[0048] The snow-blocking base can be fixed to photovoltaic brackets or other basic structures. Unlike existing clamps that are fixed to the photovoltaic module frame, it does not need to consider the changes in the height of different photovoltaic module frames, and has a wide range of applications.
[0049] In addition, the snow-blocking base is equipped with a first hook for connecting to the snow-blocking net, and the snow-blocking base is connected to a first fastener for fixing the snow-blocking net. The first hook facilitates quick connection of the snow-blocking net to the snow-blocking base, and the first fastener further increases the reliability of the snow-blocking net.
[0050] Specifically, the snow-blocking base 3 includes a vertically arranged vertical plate 31, with the first hook 33 located on the upper part of the snow-facing side of the vertical plate. The snow-facing side of the vertical plate 31 has a side-bent ear plate 34 below the first hook, which abuts against the snow-blocking net 2 and is connected to a first fastener. The ear plate has a fixing hole, which can be a slotted hole 341. When installing the snow-blocking net, the snow-blocking net is first connected to the snow-blocking base via the first hook, and then the first fastener is connected, facilitating quick and easy fixing. Because the vertical plate is perpendicular to the snow-blocking net, the side-bent ear plate 34 is provided for connection to the first fastener.
[0051] Furthermore, the snow-facing side of the vertical plate 31 extends obliquely relative to the inclined surface where the photovoltaic array is located, forming an obtuse angle. A shoulder 35, connected to the snow-blocking net 2, is located on the upper middle part of the snow-facing side of the vertical plate, and a waist 36, connected to the snow-blocking net, is located on the lower middle part of the snow-facing side of the vertical plate. Correspondingly, the snow-blocking net 2 has a multi-segment bending structure from top to bottom. As can be seen from the side view, the upper side of the snow-blocking net 2 has a first bending section 21, which is connected to a first hook 33, and the lower side of the snow-blocking net 2 has a second bending section 23, which is connected to the shoulder 35. Thus, through the multi-segment bending structure of the snow-blocking net, the mesh of the snow-blocking net is connected to the first hook and shoulder on the snow-facing side of the vertical plate, forming multiple fixing points along the height direction of the snow-blocking net, providing multi-directional support and preventing damage from skiing impacts. In addition, the snow net 2 has a central bend 22 in its middle section, which abuts against the ear plate 34. The first fastener is a bolt, and the ear plate has fixing holes for connecting to the bolt. In this way, the central bend 22 and the ear plate 34 form a stacked structure, which facilitates the bolt fixing the two together.
[0052] Furthermore, the snow net 2 has a lower bend 24 on the lower side of the second bend 23, which abuts against the waist 36. This adds another layer of support in the height direction, improving the overall support strength. The snow net 2 has an upper bend 25 on the upper side of the first bend 21. Additionally, both the upper and lower edges of the snow net 2 have bends. This multi-segment bend structure of the snow net also enhances its structural strength.
[0053] To facilitate the fixing of the snow-blocking base to the longitudinal beam, the snow-blocking base 3 includes a base plate 32 that is vertically connected to the bottom of the vertical plate. The base plate 32 extends to the side of the vertical plate, and the base plate 32 is connected to a second fastener that is fixed to the longitudinal beam 11.
[0054] like Figure 1 As shown, in one embodiment, the longitudinal beam 11 is made of U-shaped or C-shaped steel with its opening facing upwards. The second fastener is a press-fit bolt 321. The base plate 32 is located below the longitudinal beam and is fixed to the bottom wall of the longitudinal beam by the press-fit bolt 321. The bottom wall of the longitudinal beam has fixing holes for connecting to the press-fit bolts, facilitating fixation. These fixing holes can also be oblong. The vertical plate 31 has a second hook 37. While the base plate is fixed to the bottom wall of the longitudinal beam by the press-fit bolt, the second hook 37 engages with the opening of the U-shaped or C-shaped steel, ensuring reliable fixation and preventing loosening.
[0055] like Figure 5 and Figure 6 As shown, in another embodiment, the longitudinal beam 11 is also made of U-beam or C-beam, but with the opening facing laterally. The second fastener is a bolt, and the base plate 32 is located outside the longitudinal beam and fixed to the side wall of the longitudinal beam by bolts. The bolts here are not limited to press-fit bolts; other conventional bolts can also be used. Of course, the base plate and the side wall of the longitudinal beam are provided with corresponding fixing holes.
[0056] Understandably, snow shield bases can be fixed not only to longitudinal beams, but also to substrates such as concrete slabs and wooden boards by using expansion bolts.
[0057] The above description is merely a specific embodiment of the utility model, but the scope of protection 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 content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
