[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] Referring to existing technologies, in existing photovoltaic power stations installed on sloping roofs, photovoltaic modules are installed on guide rails, and hook assemblies are provided between the guide rails and the sloping roof. Since the installation structure of the hook assemblies is fixed, when installed vertically, the length direction of the photovoltaic guide rail is perpendicular to the slope direction of the sloping roof, and when installed horizontally, the length direction of the photovoltaic guide rail is consistent with the slope direction of the sloping roof. Since photovoltaic modules are mostly installed vertically, the hook assemblies are also designed for vertical installation, which makes it difficult to adapt to horizontal installation. Therefore, the conventional photovoltaic guide rail hook installation structure cannot be compatible with both horizontal and vertical arrangements of photovoltaic modules.

[0046] To accommodate both horizontal and vertical mounting of photovoltaic modules, refer to Figures 1 to 20As shown, this embodiment provides a quick-installation structure for a photovoltaic guide rail, installed on a sloping roof as part of a rooftop photovoltaic power station. It includes a hook assembly 1, a support plate 2, a guide rail 3, a guide rail fixing component 4, and a fastener 46. The hook assembly 1 has a supporting hook 13 at its top, with a supporting portion 132 parallel to the sloping roof. The support plate 2 is mounted on the supporting portion 132. The guide rail 3 and the guide rail fixing component 4 are mounted on the support plate 2. The guide rail fixing component 4 has a pressing portion 41 that presses against the guide rail 3. The fastener 46 connects the guide rail fixing component 4, the support plate 2, and the supporting portion 132. The fastener, such as a bolt, can be loosened and tightened. The support plate 2 can rotate relative to the fastener 46 when the fastener 46 is loosened, and the support plate 2 has a first installation angle and a second installation angle when the fastener 46 is tightened. The support plate 2 corresponds to the vertical installation state of the photovoltaic module at the first installation angle, and the support plate 2 corresponds to the horizontal installation state of the photovoltaic module at the second installation angle. Here, the first installation angle can be regarded as the width direction of the support plate being consistent with the tilt direction of the sloping roof, and the second installation angle can be regarded as the width direction of the support plate being perpendicular to the tilt direction of the sloping roof.

[0047] like Figures 1 to 6 As shown, when the photovoltaic modules are installed vertically, the length direction of the photovoltaic modules is aligned with the longitudinal direction of the photovoltaic module array (i.e., the front-to-back direction of the building), and the length direction of the guide rail is perpendicular to the tilt direction of the sloping roof. Additionally, as... Figures 11 to 16 As shown, when the photovoltaic modules are installed horizontally, the mounting structure of the hook assembly remains unchanged. The support plate can rotate 90 degrees around the fastener as the axis, which is equivalent to the support plate and the guide rail and guide rail fixing components mounted on it rotating 90 degrees together around the fastener as the axis. In this way, the position and installation relationship between the guide rail and the support plate do not change. However, compared with the vertical installation, the length direction of the guide rail is now consistent with the inclination direction of the sloping roof. Therefore, the photovoltaic guide rail hook-type installation structure in this embodiment can be compatible with both horizontal and vertical arrangements of photovoltaic modules.

[0048] The installation of the above-mentioned photovoltaic rail quick-installation structure includes the following steps:

[0049] Install the hook assembly, wherein the hook base is fixed to the mounting surface, and the adjustable hook and the support hook are installed in sequence;

[0050] Install the guide rail, place the tray on the support hook, put the guide rail on the tray, and then fasten the guide rail fixing parts, tray and support hook. The pressing part of the guide rail fixing parts presses against the guide rail, and at the same time the first side limiting structure and the second side limiting structure cooperate to lock the guide rail.

[0051] Furthermore, when installing the guide rails, the tray should be positioned at either the first or second installation angle, depending on the vertical or horizontal installation requirements of the photovoltaic modules.

[0052] Because the pressure plate can only press down on one side of the photovoltaic guide rail, and the other side of the photovoltaic guide rail is not sufficiently pressed down in the existing technology, there is a risk of the guide rail loosening and misalignment during use. To achieve multi-directional locking of the guide rail and prevent loosening and misalignment, a first-side limiting structure is provided between the support plate 2 and the first side of the width of the guide rail 3, and a second-side limiting structure is provided between the guide rail fixing member 4 and the second side of the width of the guide rail 3. In this way, the pressing part, the first-side limiting structure, and the second-side limiting structure work together to lock the guide rail in multiple directions, preventing loosening and misalignment.

[0053] In some embodiments, for the first-side limiting structure, the first side of the tray is provided with a first limiting side 21 that cooperates with the first-side limiting of the guide rail. The first limiting side 21 has a limiting protrusion 24, and the first side of the guide rail's width has a limiting recess 31. Thus, the first limiting side 21 cooperates with the first side of the guide rail's width, and the limiting protrusion 24 is embedded in the limiting recess 31. Therefore, the first limiting side has a translational limiting function. On the first side of the guide rail's width, the limiting protrusion is embedded in the limiting recess, providing vertical limiting. The pressing part presses against the second side of the guide rail's width, thus limiting the vertical direction on both sides of the guide rail's width.

[0054] In some embodiments, a fixing groove 32 is provided on the second side of the bottom of the guide rail 3. The pressing part 41 cooperates with the fixing groove 32 to press and fix the guide rail 3. Specifically, the fixing groove 32 is recessed towards the middle of its width. The fixing groove 32 includes a bottom wall, a first side wall 34, and a second side wall 33, and the first side wall 34 is inclined. The bottom surface of the pressing part presses against the bottom wall. The second side limiting structure includes a first inclined surface 411 provided on the pressing part, and the first inclined surface 411 is limited and cooperates with the first side wall 34. A bridging groove 412 is provided between the pressing part 41 and the main body of the guide rail fixing member. The second side limiting structure also includes a second limiting vertical surface 42 provided on the second side of the bridging groove, and the second limiting vertical surface 42 is limited and cooperates with the second side wall 33. Therefore, after the fastener is tightened, the guide rail fixing member is subjected to a downward force, mainly relying on the pressing force generated by the bottom surface of the pressing part against the bottom wall of the fixing groove. The limiting cooperation between the first inclined surface and the first side wall can prevent horizontal misalignment between the guide rail fixing member and the guide rail. Similarly, the second limiting facade and the second side wall limiting mechanism work together to achieve a similar effect.

[0055] Furthermore, to enhance the function of the second-side limiting structure, the second-side limiting structure also includes a friction surface 43 disposed on the guide rail fixing member. The friction surface 43 engages with the upper limiting portion of the second side of the guide rail width. Since the friction surface has a certain degree of elasticity, the engagement between the friction surface and the upper limiting portion of the second side of the guide rail width, along with the first inclined surface, the second limiting surface, and the friction surface, work together to limit the guide rail.

[0056] In some embodiments, the second side of the tray 2 is provided with a second limiting side 22 that cooperates with the second side of the guide rail fixing member. The second limiting side 22 has a lower limiting slope, and the second side of the guide rail fixing member has an upper limiting slope 44 that cooperates with the lower limiting slope. Taking a bolt as an example, during the tightening process, the guide rail fixing member moves downwards, simultaneously moving the width of the guide rail to the second side. The second limiting structure then comes into play, causing the first and second limiting structures to cooperate in locking the guide rail, and fixing the relative position of the guide rail fixing member, thereby ensuring a fit between the first side of the guide rail fixing member and the second side of the guide rail.

[0057] Specifically, the support plate 2 is provided with a through hole 23, which is clearance-fitted with the fastener 46. Therefore, when the fastener is not fixed, the support plate 2 can rotate relative to the fastener 46.

[0058] In addition, the guide rail fixing component 4 is provided with an elongated hole 45, which is clearance-fitted with the fastener 46. Therefore, when the fastener is not fixed, the guide rail fixing component can move relative to the fastener, allowing the pressing part to extend into the fixing groove to form a fit. The fastener 46 is a hexagon socket head cap screw. The support part 132 is provided with a threaded hole. The hexagon socket head cap screw passes through the through hole 23 and the elongated hole 45 and connects with the threaded hole. Therefore, when the hexagon socket head cap screw is tightened, it generates a downward force on the guide rail fixing component, which in turn generates a downward force on the guide rail, thereby pressing the guide rail tightly.

[0059] Specifically, the top of the guide rail 3 is provided with a T-shaped mounting groove 35, which is connected to the pressure block assembly 5. The pressure block assembly 5 includes a lower pressure block 51, an upper pressure block 52, and a pressure block bolt 53. The bottom of the lower pressure block is provided with a buckle 55, which cooperates with the mounting groove 35. The top of the upper pressure block is provided with pressing flanges on opposite sides (taking the middle pressure block as an example, the side pressure block can be provided with a pressing flange on one side). Specifically, the lower pressure block is provided with elastic support legs 54 on opposite sides, the buckle 55 is located at the bottom of the elastic support legs, the top of the lower pressure block is provided with a threaded hole, and the pressure block bolt can be an internal hex bolt, which passes through the fixing hole on the upper pressure block from top to bottom and connects to the threaded hole on the lower pressure block. When installing photovoltaic modules: Align the elastic support leg on one side of the lower pressure block of the pressure block assembly with one side of the mounting groove on the upper side of the guide rail, and press down to insert both elastic support legs into the mounting groove on the upper side of the guide rail. The lower surface of the photovoltaic module is in contact with the upper surface of the guide rail, and the pressing flange of the upper pressure block presses on the upper surface of the photovoltaic module. When tightening the pressure block bolts, lift the lower pressure block up, and the buckle engages with the inner protruding edges on both sides of the mounting groove to realize the installation of the photovoltaic module.

[0060] Referring to existing technology, the hook assembly 1 includes a hook base 11, an adjustable hook 12, and a supporting hook 13. The hook base 11 includes a base plate 111 and a side plate 112 that are perpendicular to each other. The adjustable hook has a "U"-shaped structure, including a first fixed side 121, a second fixed side 123, and a bent portion 122 connecting the first and second fixed sides. The bent portion 122 has a U-shaped bent structure. The supporting hook 13 has an L-shaped structure, including a vertically connected supporting portion 132 and a connecting portion 131. The first fixed side 121 is fixed to the side plate 112, and the second fixed side 123 is mated and fixed to the connecting portion 131.

[0061] like Figure 10 As shown, in some embodiments, a hook fixing bolt 14 is provided between the second fixing edge 123 and the joint portion 131. The joint portion 131 is provided with a first connecting groove, and the second fixing edge 123 is provided with a second connecting groove. The first connecting groove can be an elongated groove extending vertically. The hook fixing bolt 14 can be adjusted vertically along the first connecting groove to adjust the relative height of the supporting hook 13. After adjustment, the hook fixing bolt 14 can be tightened.

[0062] like Figure 20 As shown, in some embodiments, a hook connector 16 is provided between the second fixed edge 123 and the joint portion 131. The joint portion 131 has a first connecting groove 124, and the second fixed edge 123 has a second connecting groove. The hook connector 16 includes a middle plate 161, an elastic connecting portion 162 on a first side of the middle plate, and a hook 163 on a second side of the middle plate. The hook 163 engages with the second connecting groove. The elastic connecting portion 162 has a cavity in the middle and barbed structures on both sides of its width. The elastic connecting portion 162 cooperates with the first connecting groove, and the barbed structures increase the limiting force. The outermost barb is longer and engages with the end face of the first connecting groove to prevent detachment. The first connecting groove can be an elongated groove extending vertically. The elastic connecting portion 162 can be adjusted vertically along the first connecting groove to adjust the relative height of the supporting hook 13. The interference fit between the elastic connecting portion and the first connecting groove is sufficient to support its position after height adjustment.

[0063] To enable adjustable installation, an adjustment structure is provided between the first fixed edge 121 and the side plate 112. The side plate 112 is provided with an adjustment groove 113.

[0064] like Figure 11As shown, in some embodiments, a hook fixing bolt 14 connects the first fixed edge 121 to the adjusting groove 113. Specifically, it can be an internal hexagon bolt with a nut located inside the T-slot, allowing the internal hexagon head of the screw to rotate. Loosening the hook fixing bolt 14 adjusts the relative position between the first fixed edge 121 and the side plate of the hook base. After adjustment, the hook fixing bolt 14 is retightened.

[0065] like Figures 15 to 17 As shown, in some embodiments, the fastener is not an internal hex bolt, but an elastic buckle 17. The elastic buckle 17 is provided with a "I"-shaped limiting pressure edge and a buckle that is vertically connected to the middle of the limiting pressure edge. The buckle passes downward through the opening on the guide rail fixing part 4, the support plate 2 and the support part 132. The barb at the free end of the buckle is limited and engaged with the lower end of the opening on the support part 132.

[0066] like Figure 18 and Figure 19 As shown, in some embodiments, the first fixed edge 121 is provided with an adjusting slider connected to the adjusting groove 113. An elastic gap is provided between the adjusting slider and the adjusting groove 113, and an elastic connector 15 is fixed in the elastic gap. The adjusting groove 113 is a T-shaped groove. The adjusting slider includes two L-shaped expansion sides 125 arranged opposite each other and a first elastic gap in the middle. The heads of the expansion sides extend into the adjusting groove, and a second elastic gap is provided between them. The heads of the expansion sides are limited and engaged with both sides of the opening of the adjusting groove.

[0067] like Figure 18 and Figure 19 As shown, the elastic connector 15 is provided with a first elastic connecting part 151 and a second elastic connecting part 152. The width of the second elastic connecting part 152 is greater than the width of the first elastic connecting part 151. The first elastic connecting part 151 is connected to a first elastic gap, and the second elastic connecting part 152 is connected to a second elastic gap.

[0068] Furthermore, barbed structures 154 are provided on both sides of the width of the first elastic connecting portion 151 and the second elastic connecting portion 152 to increase the elastic force. A through elastic cavity 153 is provided in the middle of the second elastic connecting portion 152 to increase the elastic force.

[0069] Preferably, the adjusting slide 113 has upper and lower layers. Therefore, the adjusting slider can be adjusted in position along the extension direction of the adjusting slide, or it can cooperate with adjusting slides of different layers to adjust the height. When the installation height of the hook needs to be adjusted, the second elastic connecting part 152 is inserted into the upper or lower adjusting slide. During installation, the first elastic connecting part is connected to the first elastic gap, and the second elastic connecting part is connected to the second elastic gap, thereby pressing the contact surface between the adjusting slider and the adjusting slide. The adjustable hook and the hook base will not move relative to each other, completing the connection between the two components. If it is necessary to adjust the installation position of the adjustable hook in the extension direction of the adjusting slide, the elastic cavity of the second elastic connecting part is compressed inward. The contact surfaces of the two separate, and there is no friction, so the adjustable hook can be moved to adjust the installation position.

[0070] In addition, a reinforcing inclined plate 115 is provided between the side plate 112 and the base plate 111. The base plate 111 of the hook base is provided with mounting holes 114. When installing the hook base, the assembled hook assembly is installed on the sloping roof through the mounting holes using self-tapping screws.

[0071] Preferably, the guide rail 3, the guide rail fixing member 4, and the support plate 2 can be made of stainless steel or aluminum alloy profiles. A hollow cavity running through the length of the guide rail 3 is provided in the middle, between the bottom and top mounting grooves, to save material and reduce weight.
