Description

TECHNICAL FIELD

[0001] The utility model belongs to photovoltaic power generation equipment technical field, concretely relates to a roof photovoltaic power station. BACKGROUND

[0002] In the field of household photovoltaic, household photovoltaic system components are installed on the roof of a farmer in a certain angle along the longitudinal direction, and the angle is from 15 to 45 degrees. When snow melting, the greater the angle of the photovoltaic component, the greater the probability of snow sliding. If large-area snow slides from a high place, it is easy to cause serious damage to people and property.

[0003] In order to avoid the influence of shadow shielding on photovoltaic power generation efficiency, the prior art installs a snow blocking device on the frame of the lowermost component of the photovoltaic system, which can slow down the speed of snow sliding and at the same time can divide large-area sliding snow into a small piece of snow, thereby minimizing the damage caused by snow sliding. For example, the Chinese utility model patent with the publication number CN214506987U discloses a snow blocking device for photovoltaic components, which comprises a first clamp and a second clamp for clamping with the frame of the photovoltaic component. The first clamp is provided with a U-shaped groove structure for clamping with the upper wall, the outer side wall and the lower wall of the frame, and the U-shaped groove structure extends along the lower wall. The second clamp cooperates with the extension plate of the U-shaped groove structure to clamp the lower wall. The first clamp is provided with a partition plate for blocking the snow on the photovoltaic panel of the photovoltaic component, and the partition plate is arranged on the U-shaped groove structure.

[0004] However, the first clamp and the second clamp in the snow blocking device are fixed by bolts, which is relatively complex to install. Therefore, the applicant designs a snow blocking clamp with a buckle structure to fix the snow blocking clamp with the frame. However, only relying on the buckle structure to fix with the frame, the buckle structure deforms when the snow blocking clamp is impacted by snow, which is easy to separate from the frame. CONTENT OF THE UTILITY MODEL

[0005] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a snow blocking clamp installation structure with enhanced fixation and a photovoltaic power station, which solves the problem that the existing snow blocking clamp is fixed with the frame by relying on the buckle structure, and the buckle structure deforms when the snow blocking clamp is impacted by snow, which is easy to separate from the frame.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] Firstly, a snow blocking clamp installation structure with enhanced fixation is provided, which is installed on the frame of a photovoltaic component. The snow blocking clamp installation structure comprises a snow blocking clamp and a reinforcing fixing member. The snow blocking clamp comprises a snow blocking part and a buckle part. The snow blocking part is higher than the A surface of the frame of the photovoltaic component. The buckle part is clamped with the frame of the photovoltaic component. The reinforcing fixing member is used to fix the buckle part with the frame.

[0008] Preferably, the buckle portion is provided with an L-shaped foot, which includes a vertical side and a lower foot connected to the bottom end of the vertical side, and a slot is formed between the foot and the snow shield portion to engage with the frame of the photovoltaic module.

[0009] Preferably, the buckle portion is further provided with a limiting clamping edge folded upward from the lower clamping edge, and the limiting clamping edge cooperates with the edge of the C-surface of the frame.

[0010] Preferably, the reinforcing fixing piece is provided with a U-shaped card, and the U-shaped card includes a bottom edge and a first side edge and a second side edge arranged on opposite sides of the bottom edge, the second side edge is provided with a fixing spring plate extending obliquely downward, the first side edge is elastically connected to the limiting card edge, and the fixing spring plate is elastically connected to the vertical edge.

[0011] Preferably, the snow blocking portion is provided with a snow blocking surface extending in a longitudinal arc or oblique direction.

[0012] Preferably, a bottom plate is provided at the bottom of the snow guard portion, the upper end of the buckle portion is connected to the longitudinal middle position of the bottom plate, and the longitudinal sides of the bottom plate are provided with upper pressure edges pressed on the frame A surfaces of the two longitudinally adjacent photovoltaic components.

[0013] Preferably, the snow shield is provided with a cavity above the base plate.

[0014] In addition, the utility model also provides a photovoltaic power station, including photovoltaic modules arranged in an array, and the snow blocking clamps are installed between two longitudinally adjacent photovoltaic modules and / or on the frame of the longitudinal lower photovoltaic module.

[0015] Preferably, the snow guard is mounted on the frame of the photovoltaic assembly on the lower longitudinal side, and the buckle portion further includes a snap-fit ​​spring extending outward from the vertical side, and the snap-fit ​​spring elastically abuts against the B surface of the frame.

[0016] Preferably, the engaging spring sheet includes an oblique section extending obliquely upward and a bent edge connected to the end of the oblique section, and the bent edge is elastically in contact with the B surface of the frame.

[0017] The utility model adopts the above technical solution, which has the following beneficial effects:

[0018] 1. Since the snow guard clamp is provided with a snow guard portion that is higher than the A surface of the frame, it can block and divide the snow that slides over and play a buffering role. In addition, the buckle portion fixes the snow guard clamp to prevent the snow guard clamp from falling off due to the impact of snow, without the need for additional fasteners.

[0019] To ensure the snow guard is securely fixed, a reinforcing fixture is added. This allows the buckle portion to be locked and fixed to the frame while also reinforcing the attachment. This strengthens the fixing structure between the snow guard and the frame, making it difficult for the snow guard to separate from the frame and ensuring a secure attachment.

[0020] 2. A slot is formed between the foot of the buckle part and the snow guard part, which is engaged with the frame of the first photovoltaic module adjacent in the longitudinal direction, wherein the upper side wall of the slot is engaged with the A side of the frame, and the lower side wall of the slot (i.e., the lower clamping edge) is engaged with the C side of the frame, so that the slot clamps the frame, so that the snow guard clamp is firmly fixed on the frame of the first photovoltaic module adjacent in the longitudinal direction.

[0021] 3. The limiting card edge is used to prevent the snow guard clamp from sliding longitudinally to avoid separation from the C-side of the frame. In addition, combined with the structure of the reinforced fixing part, the first side edge cooperates with the limiting card edge, and the fixed spring piece cooperates with the other side of the vertical edge, thereby reliably fixing the buckle part to the component frame.

[0022] 4. The reinforced fastener is designed with a U-shaped clip. The first side of the U-shaped clip mates with the edge of the C-side of the frame, and the fixed spring is elastically connected to the other side of the vertical edge. The fixed spring generates sufficient snapping force to lock the clip part and the frame together. The U-shaped clip design of the reinforced fastener is also easy to install, without the need for additional fasteners.

[0023] 5. The function of the snow barrier is to block the accumulated snow and slow down the speed of the snow sliding down. The snow barrier surface is arc-shaped or extends obliquely, facing the snow sliding down from above. In this way, it can bring greater resistance to the snow without affecting the normal sliding of the snow.

[0024] 6. The upper pressure edge cooperates with the snap-fit ​​part to ensure that the snow-blocking clamp is reliably fixed in the gap between the two longitudinally adjacent photovoltaic modules. One of the upper pressure edges cooperates with the card foot to form a card groove, which is engaged with the frame of the first longitudinally adjacent photovoltaic module, and the other upper pressure edge cooperates with the engaging spring piece to clamp the frame of the second longitudinally adjacent photovoltaic module. When the engaging spring piece fails, not only the vertical edge will be fitted with the B side of the frame of the second longitudinally adjacent photovoltaic module under the action of force, but also the upper pressure edge will be fitted with the A side of the frame of the lower photovoltaic module under the action of force. Therefore, under the action of the downward thrust, the vertical edge and the upper pressure edge cooperate to be fixed with the frame of the second longitudinally adjacent photovoltaic module, preventing the snow-blocking clamp from falling out.

[0025] 7. The cavity design of the snow guard not only saves materials, but also increases the structural strength of the snow guard, thereby increasing the impact resistance of the snow guard.

[0026] 8. Since the snow guard can be installed not only between two adjacent PV panels in the longitudinal direction, but also on the frame of the PV panel on the lower side in the longitudinal direction, this is equivalent to adding another snow guard compared to installing the snow guard only between two adjacent PV panels in the longitudinal direction, further improving the snow blocking and buffering effect.

[0027] 9. The locking spring is located on the same side as the bottom edge and elastically abuts against the B side of the frame. Thus, after the snow guard is installed, the locking spring acts to clamp the limit clamp edge against the edge of the C side, and simultaneously cooperates with the upper pressing edge to clamp the snow guard and the frame in multiple directions. After the reinforcing fixture is installed, the locking spring cooperates with the reinforcing fixture to achieve dual clamping of the snow guard and the frame, thereby ensuring reliable fixation.

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

[Specific implementation method]

[0043] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0044] It will be understood by those skilled in the art that, unless there is any conflict, the features in the following embodiments and implementations may be combined with each other.

[0045] The terms used in this utility model are for the purpose of describing specific embodiments only and are not intended to limit the utility model. For example, the terms "upper," "lower," "horizontal," and "vertical" used below to indicate orientation or positional relationships are based solely on the orientation or positional relationships shown in the accompanying drawings and are used solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation. Therefore, they should not be construed as limiting the utility model.

[0046] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0047] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0048] Referring to the prior art, the photovoltaic module is rectangular and has rectangular frames around it, such as Figure 4 As shown, the conventional frame has an A surface 101, a B surface 102 and a C surface 103, wherein the lower side of the A surface is provided with a mounting groove 104 for mounting a photovoltaic panel, the inner side of the B surface is provided with a hollow cavity 105, wherein the C surface 103 extends toward the inside of the photovoltaic component to form an extended edge 106.

[0049] In a photovoltaic system, several photovoltaic modules can be arranged in a rectangular array, or only a single photovoltaic module can be set. However, from an economic point of view, a photovoltaic array is usually set. This utility model is also described based on the case of setting a photovoltaic array. Figure 1 As shown, the rooftop photovoltaic power station is installed on the roof of the house. The utility model is explained by taking the installation on the sloping roof 31 of the house 3 as an example. The sloping roof 31 here can be a sloping roof with one side facing south, a sloping roof with both north and south sides, or a smaller sloping roof on the east and west sides. It can be a sloping roof naturally formed on the roof of the house, or a sloping roof formed after reconstruction in order to install a photovoltaic power station. The sloping roof on the north and south sides is taken as an example for explanation here.

[0050] The snow guard device in the prior art is installed on the front frame of the photovoltaic module at the longitudinal front end of the photovoltaic array (close to the lower edge of the sloping roof). Since the photovoltaic module is tilted, the skis slide from top to bottom, so it can also be said to be installed on the lower frame of the photovoltaic module.

[0051] Reference Figure 1As shown, this embodiment provides a rooftop photovoltaic power station anti-skid system. A plurality of photovoltaic modules 100 are arranged in an array on a sloping roof 31. Because the photovoltaic modules are tilted, snow slides longitudinally. Therefore, a snow guard 1 is installed between two longitudinally adjacent photovoltaic modules 100. In addition, a snow guard device 2 is installed longitudinally below the photovoltaic array.

[0052] In order to install the snow blocking fixture and realize the snow blocking function, such as Figure 2 and Figure 3 As shown, the snow-blocking clamp 1 includes a snow-blocking portion 11 and a snap-on portion 12. The snow-blocking portion 11 is higher than the frame A surface 101 of the photovoltaic module. The snap-on portion 12 is snap-fitted and fixed between the frames of two longitudinally adjacent photovoltaic modules. The photovoltaic module located on the upper side in the longitudinal direction is called the first longitudinally adjacent photovoltaic module, and the photovoltaic module located on the lower side in the longitudinal direction is called the second longitudinally adjacent photovoltaic module.

[0053] The snow guard clamp features a snow guard portion that extends above the frame's A surface, blocking and dividing any snow that slides past, providing a buffering effect. Furthermore, the clip secures the snow guard clamp, preventing it from falling due to the impact of accumulated snow, eliminating the need for additional fasteners. Furthermore, due to the narrow gap between adjacent photovoltaic panels, installing the snow guard clamp using other fastening structures is difficult. Using the clip facilitates quick installation.

[0054] Because snow guards are installed between two adjacent photovoltaic modules in the vertical direction, multiple snow guards can be installed in the anti-skid system of the entire roof photovoltaic power station, forming a multi-point distribution structure of snow guards. For example, at least one snow guard is installed on the longitudinal lower frame of each photovoltaic module, thereby forming not only a structure with multiple snow guards arranged horizontally, but also a structure with multiple snow guards arranged vertically. As a result, multiple snow guards are arranged in a stepped manner along the longitudinal direction, acting as a stepped buffer, thereby improving the snow-blocking and buffering effect. In this way, all snow guards can be arranged in a rectangular array, with multiple snow-blocking points forming a snow-blocking grid. After the sliding snow passes through the multiple snow guards, it not only becomes smaller in volume and eventually completely shatters, but also the stepped buffering reduces the impact force, minimizing the damage caused by the sliding snow.

[0055] It can be understood that all snow guards can be arranged in a regular rectangular array, or they can be arranged in an irregular array, that is, the lateral position of the snow guards between two longitudinally adjacent photovoltaic modules can be changed, and multiple snow guards arranged longitudinally can also be staggered in the transverse direction.

[0056] As one embodiment, the snap portion 12 includes an L-shaped foot 121, which includes a vertical side 1211 and a lower edge 1212 connected to the bottom of the vertical side. A slot is formed between the foot 121 and the snow guard portion to engage with the frame of the first photovoltaic module adjacent in the longitudinal direction. The upper side wall of the slot engages with the A side of the frame, and the lower side wall of the slot (i.e., the lower edge) engages with the C side of the frame, so that the slot clamps the frame, so that the snow guard is firmly fixed to the frame of the first photovoltaic module adjacent in the longitudinal direction. The length of the lower edge 1212 extending inwardly toward the C side of the frame does not need to extend all the way below the extended edge 106.

[0057] Furthermore, the latch portion 12 also includes a snap-on spring 122 extending outward from the side of the vertical edge opposite the bottom edge. The snap-on spring 122 elastically abuts against the frame B surface of the second longitudinally adjacent photovoltaic module. The extension distance between the lower latching edge 1212 and the snap-on spring 122 is greater than the gap between the two adjacent photovoltaic modules. Thus, when installing the snow guard, the snow guard is inserted into the gap between the two longitudinally adjacent photovoltaic modules. The snap-on spring 122 abuts against the frame B surface of the second longitudinally adjacent photovoltaic module, deforming to ensure that the lower latching edge 1212 can extend into the gap between the two longitudinally adjacent photovoltaic modules. Once the lower latching edge 1212 reaches below the frame C surface of the first longitudinally adjacent photovoltaic module, the snow guard is pushed upward along the longitudinal direction, so that the lower latching edge 1212 abuts against the C surface, completing the installation of the snow guard. When subjected to force, such as when skiing, the snow guard's snap-on spring 122 contacts the frame B of the second longitudinally adjacent photovoltaic module, generating an upward, oblique reaction force that prevents the snap-on slot from separating from the frame of the first longitudinally adjacent photovoltaic module. Consequently, the snow guard will not fall out from between the two adjacent photovoltaic modules. Even if the snap-on spring fails, the vertical edge 1211 will adhere to the frame B of the second longitudinally adjacent photovoltaic module under the downward force, preventing the snow guard from falling out.

[0058] Specifically, the engaging spring 122 includes an upwardly extending oblique segment 1221 and a bent edge 1222 connected to the end of the oblique segment. The bent edge 1222 elastically contacts the frame B surface of the second longitudinally adjacent photovoltaic module. The oblique segment extends upward to facilitate top-down installation of the snow guard. The oblique design also facilitates the generation of a greater elastic force. The bent edge creates a larger contact area with the frame B surface of the second longitudinally adjacent photovoltaic module, thereby effectively enabling the engaging spring to function.

[0059] Preferably, the snow guard 11 is provided with a snow-blocking surface 111 extending longitudinally in an arcuate or oblique manner, and a snow-guiding surface 112 is provided on the side of the snow guard facing away from the snow-blocking surface. The function of the snow guard is to block snow accumulation and slow its sliding. The snow-blocking surface is arcuate or extends obliquely, facing upwardly sliding snow. This provides greater resistance to the snow while also preventing it from sliding normally. The snow-guiding surface is designed to guide the snow to slide normally and prevent it from accumulating on the snow guard fixture. Of course, the shapes of the snow-blocking and snow-guiding surfaces can be varied, as long as they provide effective snow-blocking and snow-guiding functions.

[0060] It is understandable that the height of the snow guard is set based on the shadow calculation. When the shadow is longest on the winter solstice, its shadow just does not block the photovoltaic components, so that the snow guard will not affect the photovoltaic power generation.

[0061] Furthermore, the bottom of the snow guard portion 11 is provided with a base plate 113, the upper end of the buckle portion 12 is connected to the longitudinal middle position of the base plate, and the longitudinal sides of the base plate 113 are provided with upper pressure edges 1131 that are pressed against the frame A surfaces of two longitudinally adjacent photovoltaic modules. The upper pressure edges cooperate with the buckle portion to ensure that the snow guard clamp is securely fixed in the gap between the two longitudinally adjacent photovoltaic modules. One of the upper pressure edges cooperates with the clamping foot to form a slot that engages with the frame of the first longitudinally adjacent photovoltaic module, and the other upper pressure edge cooperates with the locking spring to clamp the frame of the second longitudinally adjacent photovoltaic module. When the locking spring fails, not only will the vertical edge be forced to adhere to the frame B surface of the second longitudinally adjacent photovoltaic module, but the upper pressure edge will also be forced to adhere to the frame A surface of the photovoltaic module below. Therefore, under the action of the downward thrust, the vertical edge and the upper pressure edge cooperate to fix the frame of the second longitudinally adjacent photovoltaic module, preventing the snow guard clamp from falling out.

[0062] Preferably, the snow guard 1 is made of stainless steel or aluminum alloy. Extrusion molding allows for industrialized production, significantly reducing costs. It also boasts high strength, is resistant to rust, and has a long service life. Furthermore, its overall flexibility facilitates installation between two vertically adjacent photovoltaic modules.

[0063] Furthermore, the snow blocking portion 11 is provided with a cavity 115 above the bottom plate 113. The cavity 115 is formed by the bottom plate 113, the snow blocking surface 111 and the snow guiding surface 112, and the wall thickness of the snow blocking surface 111 and the snow guiding surface 112 are substantially the same. Figure 3 and Figure 6 As shown, the shape of the cavity 115 changes in accordance with the shape of the snow-blocking surface 111 and the snow-guiding surface 112. Furthermore, dividing ribs 116 may be added to the cavity to create multiple small cavities. This not only saves material but also increases the structural strength of the snow-blocking portion, thereby enhancing its impact resistance.

[0064] In addition, if Figure 3 As shown, the buckle portion 12 is provided with a reinforcing rib 123 connected to the bottom plate 113, and a cavity is formed between the reinforcing rib, the bottom plate 113 and the vertical edge 1211. The reinforcing rib enhances the overall structural strength of the snow guard clamp and prevents the connection between the snow guard portion and the buckle from being broken when snow slides down quickly.

[0065] Of course, it is understandable that the structures of the above-mentioned snow shield and buckle parts can also be modified in other ways. Only some of the modifications are described below.

[0066] As one of the implementation methods, a snow guard can be installed on the frame of the photovoltaic module on the lower side. In this way, compared with installing the snow guard only between two adjacent photovoltaic modules in the longitudinal direction, it is equivalent to adding a snow guard, which further improves the snow buffering effect. However, since there are no other photovoltaic modules below in the longitudinal direction, the above-mentioned snow guard is easy to separate from the frame. In order to ensure that the snow guard is fixed reliably, such as Figure 9 and Figure 10 As shown, a corresponding design for the snow guard fixture's mounting structure is also provided, namely, a reinforcing fixture 13. This allows the buckle portion 12 to be securely engaged with the frame while the reinforcing fixture 13 secures the buckle portion 12 to the frame. This strengthens the securing structure between the snow guard fixture and the frame, making it less likely to separate from the frame and ensuring a secure connection between the snow guard fixture and the frame.

[0067] Specifically, the reinforcing fixture 13 features a U-shaped clip that secures the snap portion 12 to the frame. The U-shaped clip includes a bottom edge 131, a first side edge 132, and a second side edge 133 located on opposite sides of the bottom edge. A securing spring 134 extends below the second side edge 133. The first side edge 132 engages the C-side edge of the frame, while the securing spring 134 elastically engages the other side of the vertical edge. The securing spring generates sufficient snapping force to secure the snap portion 12 to the frame. The U-shaped design of the reinforcing fixture also facilitates installation, eliminating the need for additional fasteners.

[0068] Of course, it is understandable that the reinforcing fixing member may also be glue or screws.

[0069] In addition, in the case of installing a snow blocking clamp on the frame of the photovoltaic module on the lower longitudinal side, the structure of the snow blocking clamp can also be improved accordingly, mainly the structure of the buckle part is improved, such as Figure 11 and Figure 12As shown, the lower clamping edge is extended to extend inwardly of the C-surface of the frame. The buckle portion 12 is further provided with a limit clamping edge 124 that folds upward from the edge of the lower clamping edge. The limit clamping edge 124 is used to tightly engage the edge of the C-surface. The limit clamping edge is used to prevent the snow guard from sliding longitudinally to prevent separation from the C-surface of the frame. In combination with the structure of the reinforced fixing member, the first side edge 132 engages with the limit clamping edge 124, and the fixing spring 134 engages with the other side of the vertical edge, thereby reliably fixing the buckle portion to the component frame.

[0070] In addition, the relative positions of the engaging springs can also be changed, such as Figure 11 and Figure 12 As shown, the engaging spring piece 122 is disposed on the same side as the bottom edge 1212, and the engaging spring piece 122 elastically abuts against the frame surface B. Thus, after the snow guard is installed, the engaging spring piece acts to clamp the limiting clamping edge 124 against the edge of the C surface, and simultaneously cooperates with the upper pressing edge to clamp the snow guard and the frame in multiple directions. After the reinforcing fixture is installed, the engaging spring piece cooperates with the reinforcing fixture to achieve dual clamping of the snow guard and the frame, thereby ensuring reliable fixation.

[0071] Dust on the surface of photovoltaic modules affects their efficiency in absorbing sunlight, so they are usually cleaned regularly. Rainwater also has a cleaning effect. However, due to the tilted arrangement of photovoltaic modules, dust, rainwater, or mixed sewage can accumulate at the bottom of the module, blocking the module from receiving sunlight. Therefore, dust troughs are typically installed on the bottom of the module frame to guide both water and dust. However, in existing technology, dust troughs and snow guards are designed and installed separately, increasing the overall cost of the photovoltaic system.

[0072] In order to make the snow blocking clamp have the dust guiding function, the snow blocking clamp is increased with a dust guiding structure to form a snow blocking clamp with a dust guiding function. One implementation method is as follows: Figure 5 As shown, a dust guide structure is provided between the snow guard clamp 1 and the frame of the photovoltaic module. Corresponding to the snow guard clamp structure with the snow guard portion 11 and the buckle portion 12, the clamping groove is provided with a dust guide structure for receiving dust, sewage, etc. entering from the surface of the photovoltaic module and then discharging them.

[0073] Specifically, the dust guide structure includes a longitudinal dust guide channel provided between the upper side wall of the card slot and the frame surface A. The edge of the upper side wall of the card slot is provided with a dust guide edge 114. The dust guide edge 114 extends beyond the inner side of the frame surface A and forms a dust guide inlet between the surface of the photovoltaic module. The dust guide inlet is connected to the longitudinal dust guide channel. A transverse dust guide channel is provided between the outer side wall of the card slot and the frame surface B. The dust guide inlet, the longitudinal dust guide channel, and the transverse dust guide channel form a complete dust guide channel, wherein the dust guide inlet can guide dust and water from the dust guide inlet, and then flow along the longitudinal dust guide channel and the transverse dust guide channel in sequence, and finally be discharged, thereby realizing the water and dust guide functions. This expands the function of the snow guard clamp, realizes multiple uses of one item, and achieves the purpose of saving the overall cost of the photovoltaic system.

[0074] The dust guide edge 114 extends obliquely downward toward the surface of the photovoltaic module and is provided with a serrated structure 1141. This forms multiple small-sized dust guide inlets, which facilitates the introduction of dust and water from the dust guide inlets. It also serves as an extension of the upper pressure edge, improving the reliability of the engagement between the card slot and the frame.

[0075] In addition, the upper sidewall of the slot is provided with first protrusions 1133 spaced laterally, and a longitudinal dust guide channel is formed between two adjacent first protrusions 1133. The upper sidewall of the slot is provided with openings 1132 between adjacent first protrusions 1133. Some water and dust can also enter the longitudinal dust guide channel through the openings. A space 1134 is provided between the first protrusions 1133 and the front sidewall of the slot, allowing the longitudinal dust guide channel to extend longitudinally and communicate with the space. The front sidewall of the slot is provided with second protrusions 1213 extending laterally, forming a transverse dust guide channel 1135 between the front sidewall of the slot and side B of the frame. The transverse dust guide channel 1135 communicates with the longitudinal dust guide channel through the space 1134. The second protrusion 1213 is positioned adjacent to the lower clamping edge, positioning the transverse dust guide channel at the upper side and communicating with the space above. Since the transverse dust guide channel is connected at both ends, dust and water can ultimately be discharged from the snow guard.

[0076] Another embodiment of the snow blocking fixture with dust guiding function is as follows Figures 6 to 8 As shown, the structure of the snow guard is Figure 5 Different from what is shown, Figure 5 In the embodiment, the snow blocking surface 111 is a convex arc surface, the snow guiding surface 112 is a sloped surface, and Figures 6 to 8 In the figure, the snow blocking surface 111 includes a middle convex arc surface 1112, an upper convex arc surface 1111 at the upper end, and a vertical side 1113 at the lower end, wherein the upper end of the vertical side is higher than the lower end of the convex arc surface 1112.

[0077] Of course, other structures of the snow guard clamp can also be modified in many ways, which will not be described in detail here.

[0078] refer to Figure 9 As shown, although a reinforcing fixing member 13 is added, the structure of the snow blocking clamp remains unchanged and a dust guiding structure can still be provided.

[0079] refer to Figure 11 and Figure 12 As shown in the figure, the snow guard clamp 1 also has a dust guide structure, but the structure of the transverse dust guide channel has been changed, wherein the engaging spring piece 122 elastically abuts against the frame B surface to form a transverse dust guide channel.

[0080] It is understandable that a snow-blocking clamp can be installed in the horizontal middle position of the lower side of the photovoltaic module frame, or a snow-blocking clamp can be installed near the horizontal end position of the lower side of the photovoltaic module frame. Of course, according to actual needs, multiple snow-blocking clamps can be set along the horizontal side of the lower side of the photovoltaic module frame 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.

[0081] In one embodiment, the snow guard device 2 comprises a snow guard shaft extending laterally above the sloping roof, and a plurality of snow guards mounted laterally side by side on the shaft. The snow guard device has an open and closed state. A motor drives the snow guard shaft to rotate, which in turn drives the snow guards to open and close. In the closed state, the space between the snow guards and the sloping roof is sealed. In the open state, the snow guard shaft drives the snow guards to move, creating a snow-draining space between the snow guards and the sloping roof. Snow that falls from the photovoltaic array is discharged through the snow-draining space.

[0082] The aforementioned snow guard device is used in conjunction with the snow guard fixture installed on the photovoltaic array. Because the snow guard fixture has already broken up and cushioned the falling snow, not only is its volume reduced, but the impact force is also reduced after the step-by-step cushioning. When the falling snow slides off the photovoltaic array, the potential energy generated will cause the snow to continue sliding down. To ensure the orderly discharge of the falling snow, a snow guard device is installed longitudinally below the photovoltaic array. The snow guard device has an open state and a closed state. In the closed state, the space between the snow guard and the sloping roof is closed. In the open state, a snow discharge space is formed between the snow guard and the sloping roof, and the snow that slides off the photovoltaic array is discharged through the snow discharge space. Because the snow guard device achieves orderly snow discharge, the impact force is reduced during the snow discharge process, and it also has a certain snow crushing effect.

[0083] Therefore, the cooperation between the snow guard device and the snow guard clamp can not only break and cushion the skis, but also make the skis discharged in an orderly manner, avoiding the disorderly sliding of snow, thereby reducing the range of snow impacting the ground, reducing the threat of snow impact to temporary buildings and the lives and property of passers-by, and completely solving the safety risk problem caused by large pieces of snow sliding on the surface of photovoltaic modules.

[0084] 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 will understand that the utility model includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the utility model are intended to be included within the scope of the claims.
