Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to a photovoltaic system using a side-pressure block for installation. Background Technology

[0002] Currently, the locking method for photovoltaic modules mainly uses side pressure blocks with non-adjustable height. The side pressure blocks are connected to the fixing pads with fasteners to press the photovoltaic modules tightly.

[0003] There are many specifications and models of components on the market, and the dimensions of each specification are different. Common frame heights are 30mm, 33mm, 35mm, 40mm, etc. Currently, each component requires the use of side clamps of corresponding height for fixed installation. Because the pace of component updates on the market is very fast, this poses a significant problem for inventory and supply chain consumption.

[0004] To achieve adjustable height of the side clamping block, existing technologies have proposed many solutions. Referring to Chinese utility model patent CN 220291955U, a universal detachable photovoltaic module mounting clamping block is disclosed, including a clamping base for fixed connection with a photovoltaic bracket and a clamping head for clamping the photovoltaic module frame. The clamping head has an L-shaped structure, including a vertical section for connecting with the clamping base and a clamping section for pressing against the surface of the photovoltaic module frame. The clamping head and the clamping base are detachably connected, and a height adjustment mechanism is provided on the contact surface for adjusting the position of the clamping head along the height direction of the photovoltaic module frame. The height adjustment mechanism uses the cooperation of a mounting protrusion and a mounting groove to match photovoltaic modules of different thicknesses. However, when adjusting the height, the mounting protrusion needs to be separated from the original mounting groove and then combined with a new mounting groove, making the adjustment process rather cumbersome. Utility Model Content

[0005] To address the shortcomings of existing technologies, the present invention aims to provide an adjustable photovoltaic side pressure block assembly and a photovoltaic system, in which the side pressure block in the adjustable photovoltaic side pressure block assembly does not need to be separated from the pressure block base when the height of the side pressure block is adjusted.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] First, an adjustable photovoltaic side pressure block assembly is provided, including a pressure block base, a side pressure block disposed above the pressure block base, and fasteners connecting the pressure block base and the side pressure block. An oblique sliding adjustment structure is provided between the side pressure block and the pressure block base. When the side pressure block slides obliquely through the oblique sliding adjustment structure, the relative height is adjusted so that the side pressure block can be matched with photovoltaic modules of different heights.

[0008] Preferably, the inclined sliding adjustment structure includes an inclined groove provided on the base of the pressure block and an inclined slider provided on the side pressure block. The inclined slider slides obliquely along the inclined groove to adjust the relative height of the side pressure block.

[0009] Preferably, the pressure block base has a sliding groove boss on the side away from the photovoltaic module, and the inclined sliding groove is provided on the sliding groove boss; and / or, the pressure block base has a first fixing hole for connection with fasteners on the side near the photovoltaic module.

[0010] Preferably, the slide boss has a first inclined groove wall on the side near the photovoltaic module; and / or, the slide boss has a right-angled triangular protrusion on the side away from the photovoltaic module, and the hypotenuse of the right-angled triangular protrusion forms the second inclined groove wall of the inclined slide.

[0011] Preferably, the side pressing block includes a pressing block body and a pressing part connected to the side of the pressing block body near the photovoltaic module. The pressing block body is provided with a second fixing hole for connection with a fastener. The second fixing hole is an elongated hole. The pressing part has an L-shaped structure and includes a vertically connected lateral side and a pressing side.

[0012] Preferably, the pressure block body is provided with a reinforcing protrusion, and the second fixing hole is opened on the reinforcing protrusion; and / or, the inclined slider is connected to the pressure block body through a vertical transition portion.

[0013] Preferably, the side pressure block assembly further includes a pressure block fixing pad disposed below the pressure block base, and the fastener passes through the pressure block base and is fixed to the pressure block fixing pad.

[0014] Preferably, the pressure block fixing pad has a U-shaped structure and is provided with threaded holes for connection with fasteners.

[0015] Preferably, the fastener is an internal hex bolt; and / or, the pressure block base and the side pressure block are made of aluminum alloy profiles.

[0016] Additionally, a photovoltaic system is provided, including purlins, photovoltaic modules, and a side-pressure block assembly for fixing the photovoltaic modules to the purlins, wherein the side-pressure block assembly is the side-pressure block assembly described above.

[0017] The present invention adopts the above technical solution and has the following beneficial effects:

[0018] 1. Since the side pressure block and the pressure block base are provided with an oblique sliding adjustment structure, that is, the side pressure block can slide obliquely relative to the pressure block base through the mutually cooperating oblique sliding mating surfaces. Therefore, when the side pressure block slides obliquely, the relative height of the side pressure block can be adjusted so that the side pressure block can be matched with photovoltaic modules of different heights, and the side pressure block and the pressure block base do not need to be separated during the adjustment process.

[0019] Fasteners are used to connect the pressure block base and the side pressure block. Before tightening the fasteners, the side pressure block can be slid obliquely through the oblique sliding adjustment structure to adjust its height relative to the pressure block base. After adjustment, the side pressure block can be matched with the photovoltaic module of the corresponding height. Finally, the fasteners are tightened to press the side pressure block firmly against the photovoltaic module.

[0020] The side-pressure block assembly can be used with photovoltaic modules of different heights. If the photovoltaic module is tall, the side-pressure block needs to be raised by sliding it upwards at an angle; if the photovoltaic module is short, the side-pressure block needs to be lowered by sliding it downwards at an angle. After height adjustment, the side-pressure block can adapt to photovoltaic modules of different heights. Therefore, the side-pressure block assembly is universal, solving the problem of having to replace the corresponding side-pressure block in stock when changing module height, thus streamlining materials and facilitating material management. Moreover, the adjustment process is smooth, without needing to separate the side-pressure block from the pressure block base, making the adjustment process more convenient and faster.

[0021] 2. The inclined slider slides obliquely along the inclined groove to adjust the relative height of the side pressure block. When assembling the side pressure block with the pressure block base, after aligning the inclined slider with the inclined groove, push the inclined slider horizontally into the inclined groove to assemble the side pressure block and the inclined slider. Then, after placing the pressure block base on the guide rail, the side pressure block can slide obliquely to adjust its height to accommodate photovoltaic modules of different heights. During the oblique sliding process, the inclined slider and the pressure block base do not separate. Furthermore, when the fasteners are tightened, the inclined sliding engagement bottom surface of the inclined slider and the inclined groove presses together, thereby ensuring that while one side of the side pressure block presses against the photovoltaic module, the other side receives stable support from the oblique sliding engagement bottom surface, guaranteeing stable pressing of the photovoltaic module by the pressing part.

[0022] 3. The base of the pressure block has a sliding groove boss on the side away from the photovoltaic module, and the inclined sliding groove is provided on the sliding groove boss, which facilitates the formation of the inclined sliding groove. Furthermore, the sliding groove boss has a first inclined groove wall on the side closer to the photovoltaic module, and a right-angled triangular protrusion on the side away from the photovoltaic module, with the hypotenuse of the right-angled triangular protrusion forming the second inclined groove wall of the inclined sliding groove. Thus, an inclined sliding groove is formed within a limited space. Part of the force from the side pressure block presses against the photovoltaic module, and the other part acts on the second inclined groove wall. Therefore, the structural strength of the right-angled triangular protrusion is sufficient to provide reliable support for the inclined slider.

[0023] 4. Since the pressure block body is provided with a second fixing hole for connecting to the fastener, the second fixing hole is an elongated hole whose length direction is consistent with the guide rail direction. Therefore, even if the side pressure block is adjusted in height and moves horizontally relative to the fixed base, the second fixing hole can still be partially aligned with the first fixing hole. Thus, the fastener can pass through the first fixing hole and the second fixing hole. Furthermore, during the adjustment process, the side pressure block, the fixed base, and the fastener do not need to be separated.

[0024] 5. Because the pressure block body is provided with reinforcing protrusions, the second fixing hole is opened on the reinforcing protrusions. Therefore, the reinforcing protrusions enhance the structural strength of the pressure block body and prevent the setting of the second fixing hole from weakening the structural strength of the pressure block body.

[0025] 6. The pressure block fixing pad is located inside the guide rail. During installation, the pressure block fixing pad slides into the guide rail from the end of the guide rail, and the two sides of the pressure block fixing pad engage with the inner folded edge. During the tightening of the hexagon socket bolt, the hexagon socket bolt engages with the threaded hole, which drives the pressure block fixing pad to rise. Finally, the pressure block fixing pad engages with the pressure block base and is fixed to the guide rail. The side pressure block is fixed to the pressure block base, and at the same time, the pressing part of the side pressure block presses the photovoltaic module.

[0042] Based on existing technology, photovoltaic modules are mounted on guide rails using side-mounted blocks. In practical applications, photovoltaic modules come in various heights; to facilitate adjustment of the side-mounted blocks according to the different frame heights of the photovoltaic modules, such as… Figures 1 to 8 As shown, this embodiment provides an adjustable photovoltaic side pressure block assembly 1, including a pressure block base 11, a side pressure block 12 disposed above the pressure block base, and fasteners connecting the pressure block base 11 and the side pressure block 12. An oblique sliding adjustment structure is provided between the side pressure block 12 and the pressure block base 11. The side pressure block 12 adjusts its relative height when sliding obliquely through the oblique sliding adjustment structure, so that the side pressure block 12 can cooperate with photovoltaic modules of different heights.

[0043] Because the side pressure block and the pressure block base are provided with an oblique sliding adjustment structure, that is, the side pressure block can slide obliquely relative to the pressure block base through the mutually cooperating oblique sliding mating surfaces, the relative height of the side pressure block can be adjusted when the side pressure block slides obliquely, so that the side pressure block can be matched with photovoltaic modules of different heights, and the side pressure block and the pressure block base do not need to be separated during the adjustment process.

[0044] Fasteners are used to connect the pressure block base and the side pressure block. Before tightening the fasteners, the side pressure block can be slid obliquely through the oblique sliding adjustment structure to adjust its height relative to the pressure block base. After adjustment, the side pressure block can be matched with the photovoltaic module of the corresponding height. Finally, the fasteners are tightened to press the side pressure block firmly against the photovoltaic module.

[0045] The diagram illustrates the interaction between the side-pressure block 12 and two photovoltaic modules of different heights: a first photovoltaic module 3 with a height of 35mm and a second photovoltaic module 4 with a height of 30mm. If the photovoltaic module is taller, the side-pressure block 12 needs to be adjusted upwards by sliding diagonally; conversely, if the photovoltaic module is shorter, the side-pressure block 12 needs to be adjusted downwards by sliding diagonally. Figure 4As shown, after height adjustment, the side pressure block 12 is higher for the first photovoltaic module 3, with the inclined slider 123 having a certain distance from the lowest point of the inclined slide groove 112. For the second photovoltaic module 4, the side pressure block 12 is lower, with virtually no gap between the inclined slider 123 and the lowest point of the inclined slide groove 112. Therefore, the side pressure block 12 can adapt to photovoltaic modules of different heights, and the side pressure block assembly 1 is universal, solving the problem of needing to replace the corresponding side pressure block in inventory due to module height changes. This simplifies materials, facilitates material management, and the adjustment process is smooth, eliminating the need to separate the side pressure block from the pressure block base, making the adjustment process more convenient and faster.

[0046] Understandably, as the side pressure block slides obliquely, its horizontal position relative to the pressure block base also changes, but it must maintain a constant horizontal position with the photovoltaic module. For example... Figure 4 As shown, corresponding to the first photovoltaic module 3, the pressing base 11 is connected to the B side of the first photovoltaic module frame, and corresponding to the second photovoltaic module 4, the pressing base 11 is at a certain distance from the B side of the second photovoltaic module frame.

[0047] In some embodiments, the oblique sliding adjustment structure includes an oblique groove 112 on the pressure block base 11 and an oblique slider 123 on the side pressure block 12. The oblique slider 123 slides obliquely along the oblique groove 112 to adjust the relative height of the side pressure block 12. When the side pressure block 12 is combined with the pressure block base 11, the oblique slider is aligned with the oblique groove and then pushed horizontally into the oblique groove, thereby combining the side pressure block and the oblique slider. After the pressure block base is placed on the guide rail, the side pressure block can slide obliquely to adjust its height to accommodate photovoltaic modules of different heights. During the oblique sliding process, the oblique slider and the pressure block base do not separate. Furthermore, when the fasteners are tightened, the oblique sliding engagement bottom surface of the oblique slider and the oblique groove presses together, thereby ensuring that the pressing part on one side of the side pressure block presses against the photovoltaic module while the other side receives stable support from the oblique sliding engagement bottom surface, guaranteeing that the pressing part stably presses against the photovoltaic module.

[0048] like Figure 7As shown, the pressure block base 11 has a sliding groove boss on the side away from the photovoltaic module, and the inclined sliding groove 112 is provided on the sliding groove boss. This facilitates the formation of the inclined sliding groove. The pressure block base 11 has a first fixing hole 115 for connection with fasteners on the side near the photovoltaic module. The sliding groove boss has a first inclined groove wall 113 on the side near the photovoltaic module. The outer side of the first inclined groove wall is an inclined surface, eliminating the need for a vertical surface and saving materials. The sliding groove boss has a right-angled triangular protrusion 111 on the side away from the photovoltaic module, and the hypotenuse of the right-angled triangular protrusion forms the second inclined groove wall 114 of the inclined sliding groove. Part of the force of the side pressure block presses against the photovoltaic module, and the other part acts on the second inclined groove wall. Therefore, the structural strength of the right-angled triangular protrusion is sufficient to provide reliable support for the inclined slider. In addition, the inner side of the right-angled triangular protrusion 111 has a hollow cavity 116, which has the effect of weight reduction and material saving.

[0049] like Figure 8 As shown, the side pressure block 12 includes a pressure block body 121 and a pressing part 122 connected to the side of the pressure block body near the photovoltaic module. The pressure block body 121 is provided with a second fixing hole 126 for connection with fasteners. The second fixing hole 126 is an elongated hole, and its length direction is consistent with the direction of the guide rail. Therefore, even if the side pressure block is adjusted in height and moves horizontally relative to the fixed base, it can still ensure that part of the second fixing hole can still be aligned with the first fixing hole, so that the fastener can pass through the first fixing hole and the second fixing hole. During the adjustment process, the side pressure block, the fixed base and the fastener do not need to be separated. The pressing part 122 has an L-shaped structure, including a vertically connected side edge and a pressing edge. The side edge is limited and cooperates with the B side of the photovoltaic module frame, and the pressing edge presses against the A side of the photovoltaic module frame.

[0050] Furthermore, the pressure block body 121 is provided with a reinforcing protrusion 125, and the second fixing hole 126 is formed on the reinforcing protrusion. The reinforcing protrusion enhances the structural strength of the pressure block body and prevents the setting of the second fixing hole from weakening the structural strength of the pressure block body. In addition, the inclined slider 123 is connected to the pressure block body 121 through a vertical transition portion 124.

[0051] Furthermore, the side pressure block assembly 1 also includes a pressure block fixing pad 14 disposed below the pressure block base 11, and the fastener passes through the pressure block base 11 and is fixed to the pressure block fixing pad 14. Figure 1 As shown, the pressure block fixing pad 14 has a U-shaped structure, with a threaded hole 141 at the bottom and retaining edges 142 on both sides. The fastener is an internal hex bolt 13, which is connected to a spring washer 15 and a flat washer 16. Figure 2 As shown, the pressure block fixing pad 14 is located inside the guide rail 2. The guide rail is made of C steel and has L-shaped inner folded edges 21 on both sides of its opening. The two side clamping edges 142 of the pressure block fixing pad are engaged in the inner folded edges.

[0052] The above technical solution involves first sliding the inclined slider of the side pressure block into the inclined groove of the pressure block base. Then, using an internal hex bolt, the bolt passes sequentially through the spring washer, the flat washer, the second fixing hole on the side pressure block, and the first fixing hole on the pressure block base, finally connecting with the threaded hole on the pressure block fixing pad and tightening it. During installation, the pressure block fixing pad slides into the guide rail from the end of the guide rail, and the two sides of the pressure block fixing pad engage with the inner folded edge. During the tightening of the internal hex bolt, the internal hex bolt, through its engagement with the threaded hole, drives the pressure block fixing pad to rise. Finally, the pressure block fixing pad engages with the pressure block base and is fixed to the guide rail, while the side pressure block is fixed to the pressure block base. Simultaneously, the pressing part of the side pressure block presses against the photovoltaic module.

[0053] Preferably, the pressure block base 11 and the side pressure block 12 are made of aluminum alloy profiles. This not only provides corrosion resistance and a long service life, but also high structural strength and resistance to deformation.

[0054] 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.
