Description

Pressed block assembly, installation method thereof, and photovoltaic system Technical Field

[0001] The present invention mainly relates to the field of photovoltaics, and in particular to a pressing block assembly, an installation method thereof, and a photovoltaic system. Background Art

[0002] A solar photovoltaic module consists of a solar panel and a profile surrounding the panel's edges. The profile provides mechanical strength and seals the panel's edges. During installation, further clamping is required to secure the module with the profile to the bracket and to connect adjacent modules.

[0003] Existing integrated profile presses or combined upper and lower profile presses used to secure profiles with side grooves require their left and right sides to be inserted into the profile's side grooves. Because their width is larger than the spacing between photovoltaic modules, removing the profile press from the center of the photovoltaic array is difficult, even if the fasteners between the modules and the profile press are loosened. The profile press or profile press assembly can only be slid out along the frame. However, the gaps between actual photovoltaic modules are not uniform and can even deform under load, making it inconvenient or even impossible to slide the profile press or profile press assembly out along the frame, making removal and replacement difficult.

[0041] Figure 1 is a front view of a profile according to an embodiment of the present application, and Figure 2 is a perspective schematic diagram of a briquetting assembly according to an embodiment of the present application. Referring to Figures 1-2 , the present application provides a briquetting assembly 10 adapted to secure two adjacent profiles 20, wherein the profiles 20 have a securing plate 21 and side grooves 22. The briquetting assembly 10 includes an upper briquetting block 100 and a lower briquetting block 200.

[0042] As shown in FIG2 , a preferred embodiment of the present application is shown. In this embodiment, the upper pressing block 100 and the lower pressing block 200 respectively have a first fastening hole 101 (see FIG3 ) and a second fastening hole 201 (see FIG5 ) extending therethrough, and the pressing block assembly 10 further includes a fastener 300 and a locking member 400, wherein the locking member 400 has a third fastening hole 401 extending therethrough, and the fastener 300 is adapted to pass through the first fastening hole 101, the second fastening hole 201, and the third fastening hole 301. Furthermore, the locking member 400 also has a locking groove 402, which is adapted to engage with the bracket 30 (not shown, but may be referred to in FIG7-10 ) after installation.

[0043] FIG3 is a perspective schematic diagram of an upper pressing block according to an embodiment of the present application, and FIG4 is a front view of an upper pressing block according to an embodiment of the present application. Referring to FIG1-4 , the upper pressing block 100 includes a first fixing portion 110, a second fixing portion 120, and a fastening portion 130. The first fixing portion 110 is located on a first side of the fastening portion 130 (on the left side as shown in FIG4 ), and the second fixing portion 120 is located on a second side of the fastening portion 130 (on the right side as shown in FIG4 ). The first fixing portion 110 and the second fixing portion 120 are respectively adapted to be clamped with two adjacent profiles 20 as shown in FIG1 . Specifically, the first fixing portion 110 and the second fixing portion 120 are respectively clamped with the lower ends 23 of the notches of the side grooves 22 of the two adjacent profiles 20.

[0044] Furthermore, in this embodiment, the upper pressing block 110 further includes a first groove 111 and a second groove 121, wherein the first groove 111 is located between the first fixing portion 110 and the fastening portion 130, and the second groove 121 is located between the second fixing portion 120 and the fastening portion 130. Further referring to FIG10 , for ease of understanding, the two adjacent profiles 20 of the pressing block assembly 10 are named as the first profile 20a and the second profile 20b, respectively. When the upper pressing block 100 is engaged with the first profile 20a and the second profile 20b, the lower end 23a of the side groove of the first profile 20a is adapted to be engaged with the first groove 111, and the lower end 23b of the side groove of the second profile 20b is adapted to be engaged with the second groove 121.

[0045] As shown in Figures 1-4, a preferred embodiment of the present application is shown. In this embodiment, a first vertical distance H1 is defined between the lower end 23 of the notch of the side groove 22 of the profile 20 and the lower surface of the profile 20. A second vertical distance H2 is defined between the first groove 111, the second groove 121, and the lower surface of the fastening portion 130 of the upper pressing block 100, with H1 > H2. Furthermore, a third vertical distance H3 is defined between the lower surface of the first fixing portion 110 and the lower surface of the fastening portion 130, and a fourth vertical distance H4 is defined between the lower surface of the second fixing portion 120 and the lower surface of the fastening portion 130, with H2 > H3 > H4. This arrangement enhances the securing effect of the upper pressing block 100. After installation, the first groove 111 and the second groove 121 are adapted to engage the lower end 23 of the notch of the profile 20. Furthermore, the first fixing portion 110 and the second fixing portion 120 horizontally limit the profile 20, preventing it from slipping off.

[0046] FIG5 is a perspective schematic diagram of a lower pressing block according to an embodiment of the present application, and FIG6 is a front view of a lower pressing block according to an embodiment of the present application. Referring to FIG1-2 and FIG5-6, the lower pressing block 200 includes a third fixing portion 210, a fourth fixing portion 220, and a supporting plate 230. The third fixing portion 210 is located on a first side of the supporting plate 230 (the left side as shown in FIG6), and the fourth fixing portion 220 is located on a second side of the supporting plate 230 (the right side as shown in FIG6). Specifically, the third fixing portion 210 has a ridge 211, and the ridge 211 has a flange 212 at an edge away from the supporting plate 230 (the upper edge as shown in FIG6). The flange 212 protrudes from the upper edge of the ridge 211 toward the direction of the fourth fixing portion 220, so that the third fixing portion 210 forms a hook similar to a "J" shape, which is suitable for clamping the fixing plate 21 of the corresponding profile 20. After the fixing is completed, the ridges 211 can limit the movement of the profile 20 in the horizontal direction, while the flanges 212 can limit the movement of the profile 20 in the vertical direction to a certain extent.

[0047] Furthermore, the fourth fixing portion 220 has an upper flange 221 and a clamping groove 222. The clamping groove 222 is located between the upper flange 221 and the carrier plate 230 and is suitable for sliding into the fixing plate 21 connected to the corresponding profile 20. It can be understood that the third fixing portion 210 and the fourth fixing portion 220 of the lower pressing block 200 are respectively suitable for fixing two adjacent profiles 20. Further referring to Figure 10, the third fixing portion 210 is suitable for clamping the fixing plate 21a of the first profile 20a, and the clamping groove 222 of the fourth fixing portion 220 is suitable for sliding into the fixing plate 22b connected to the second profile 20b.

[0048] As shown in Figures 1-6, a preferred embodiment of the present application, in this embodiment, there is a first horizontal distance L1 between the end S1 of the notch of the side groove 22 of the profile 20 away from the fixed plate 21 and the end S2 of the fixed plate 21 away from the side groove 22 (refer to Figure 1), a second horizontal distance L2 is between the two side surfaces of the fastening portion 130 of the upper pressing block 100 (refer to Figure 4), a third horizontal distance L3 is between the two edges of the upper surface of the supporting plate 230 of the lower pressing block 200 (refer to Figure 6), the flange 212 has a protruding distance L4 relative to the ridge 211 (refer to Figure 6), and 0<L3-2*L1-L2≤L4. Taking Figures 9-10 as an example, 2*L1+L2 is the distance between Sa2 and Sb2 after the first profile 20a, the second profile 20b and the pressure block assembly 10 are combined together. Sa2 is the end of the fixing plate 21a of the first profile 20a away from the side groove 22a, and Sb2 is the end of the fixing plate 21b of the second profile 20b away from the side groove 22b.

[0049] It is understood that in order to ensure that the first profile 20a can be clamped into the third fixing portion 210 under the action of gravity, L3 needs to be greater than 2*L1+L2, that is, Sa2 and Sb2 will not simultaneously abut both edges of the upper surface of the support plate 230. Assuming that Sb2 has already abutted the edge of the upper surface of the support plate 230 (the right edge as shown in Figure 10, i.e., the bottom of the clamping groove 222), there is a gap between Sa2 and the other edge of the upper surface of the support plate 230 (the left edge as shown in Figure 10), and the width of the gap is equal to L3-2*L1-L2. However, if L3 is too large, it will affect the fixing effect of the lower pressing block 200. Therefore, the width of this gap is less than the protrusion distance L4 of the flange 212 relative to the ridge 211, so that in the absence of external force, the fixing plate 21a of the first profile 20a will not vertically separate from the third fixing portion 210.

[0050] The present invention also provides a method for installing a pressure block assembly 10. Figures 7-10 illustrate the assembly process of the pressure block assembly and the profile according to one embodiment of the present invention. Referring to Figures 3-10, the assembly process of the pressure block assembly 10 and the profiles 20a and 20b is described in detail as follows:

[0051] (1) Referring to Figures 1-7, first place the second profile 20b containing the photovoltaic laminate 40 and the pressing block assembly 10 on the bracket 30. It should be noted that the lower pressing block 200 needs to be placed between the second profile 20b and the bracket 30, and the fixing plate 21b of the second profile 20b is located on the supporting plate 230. At this time, the upper pressing block 100 is suspended in the air, and the second groove 121 of the upper pressing block 100 is aligned with the lower end 23b of the side groove of the second profile 20b. The fastener 300 (not shown) is not installed yet.

[0052] (2) Referring to Figures 1-6 and 8, the lower pressing block 200 is translated along the bracket 30 in a direction away from the second profile 20b until the fixing plate 21b of the second profile 20b slides into the clamping groove 222, and then the upper pressing block 100 is placed downward until the lower end 23b of the notch of the second profile 20b is engaged with the second groove 121 of the upper pressing block 100. At this time, the first fastening hole 101 of the upper pressing block 100 and the second fastening hole 201 of the lower pressing block 200 are opposite to each other, and the fastener 300 is installed so that it passes through the first fastening hole 101, the second fastening hole 201 and the locking member 400 (not shown, refer to Figure 2) in sequence and is tightened, thereby fixing the second profile 20b to the bracket 30.

[0053] (3) Referring to Figures 1-6 and 9, the first profile 20a with the photovoltaic laminate 40 installed is placed on the lower pressing block 200 at an angle so that the lower end 23a of the side groove is inserted between the first fixing portion 110 of the upper pressing block 100 and the supporting plate 230 of the lower pressing block 200. At this time, the fixing plate 21a of the first profile 20a is overlapped on the flange 212 of the lower pressing block 200.

[0054] (4) Referring to Figures 1-6 and 10, lay the first profile 20a flat. Under the weight of the photovoltaic laminate 40 and the first profile 20a, the fixing plate 21a of the first profile 20a will snap under the flange 212. At the same time, the lower end 23a of the notch of the side groove 22a snaps into the first groove 111 of the upper pressing block 100, completing the installation. It should be noted that the protrusion distance L4 of the flange 212 relative to the ridge 211 must be less than a threshold value, which is the maximum protrusion of the flange 212. When the flange 212 is less than this threshold value, the first profile 20a naturally lays flat, allowing the fixing plate 21a to snap under the flange 212.

[0055] Specifically, after the second profile 20b on one side of the pressing block assembly 10 is installed, the staff can directly tighten the fastener 300 and then continue to install the first profile 20a on the other side. There is no need to operate the pressing block assembly 10 that has been set between the two adjacent profiles 20, which reduces the difficulty of operation and avoids the risk of irregular operations such as kneeling to press the photovoltaic components by the staff.

[0056] In addition, after the first profile 20a, the second profile 20b and the pressing block assembly 100 are installed as shown in FIG10, the next step is to continue to install another pressing block assembly 10 on the other side of the first photovoltaic module 50a installed with the first profile 20a. The installation method can also refer to FIG7. It can be understood that the position of the first photovoltaic module 50a is fixed at this time and cannot be moved. Therefore, the pressing block assembly 10 can only be moved horizontally. Specifically, lift the unfixed end of the first photovoltaic module 50a so that there is a gap between the first profile 20a and the bracket 30 to allow the other lower pressing block 200 to slide in. The following steps can refer to the above (1) to (4).

[0057] As shown in Figures 7-10, the disassembly process also does not require any manipulation of the pressure block assembly 10 already positioned between two adjacent profiles 20: First, lift the first profile 20a upward, and its fixing plate 21a will disengage from the third fastening portion 210. At this point, the operator can directly disassemble the pressure block assembly 10. After the fastener 300 is removed, the upper pressure block 100 can be directly removed. The lower pressure block 200 needs to be translated along the bracket 30 toward the second profile 20b until the fixing plate 21b slides out of the clamping groove 222 (see Figure 6). The second profile 20b can then be lifted to remove the lower pressure block 200.

[0058] Furthermore, in conjunction with reference to Figures 1-6 and 10, the upper surface of the upper pressing block 100 in the pressing block assembly 10 provided by the present invention is lower than the upper surface of the two adjacent profiles 20, and is completely located in the installation gap between the two adjacent profiles 20. After installation, it will not protrude from the photovoltaic module, ensuring aesthetics, and the upper pressing block 100 only fixes the side groove 22 of the profile 20, that is, the force-bearing surface is the B side of the profile 20 (that is, the left side as shown in Figure 1). In the prior art, the pressing block is often pressed against the A side (i.e., the upper surface) of the profile. This fixing method relies on the friction between the pressing block and the A side of the profile, and the fixing effect is poor. In order to ensure the fixing strength, the pressing block is often required to have a large pressing force on the profile, but this may cause the upper surface of the photovoltaic laminate to be cracked. The upper pressing block 100 in the present invention is pressed against the bottom of the side groove 22 of the profile 20, which can increase the pressing force to ensure that the profile 20 does not undergo lateral displacement while avoiding damage to the photovoltaic laminate, thereby enhancing the service life.

[0059] Furthermore, the present invention provides a pressure block assembly 10 in which the fixing plate 21 (i.e., the extended C-side) of the profile 20 is fixed by a lower pressure block 200, which further enhances the fixing effect compared to the method of fixing only the B-side and reduces the requirement for the thickness of the extended C-side compared to the method of fixing only the C-side. Specifically, if only the B-side of the profile is fixed, under severe weather conditions such as strong winds, the photovoltaic module may be tilted, causing the profile and the pressure block to separate, resulting in economic losses. When only the extended C-side is fixed, the C-side needs to have a certain thickness and strength to avoid damage to the profile, and the fixing effect is not good. In the present invention, the lower pressure block 200 further fixes the C-side of the pressure block 20 and adopts an asymmetric design. While the fourth fixing portion 220 limits the profile 20 in the vertical direction through the clamping groove 222, the third fixing portion 210 is provided with a ridge 211 and a flange 212, solving the problem of difficult installation and disassembly.

[0060] FIG11 is a perspective schematic diagram of a pressure block assembly according to another embodiment of the present application, and FIG12 is a perspective schematic diagram of a lower pressure block according to another embodiment of the present application. Referring to FIG11-12 , the pressure block assembly 10′ in this embodiment includes an upper pressure block 100′, a lower pressure block 200′, a fastener 300′, a locking member 400′, and a piercing screw 500. The support plate 230′ of the lower pressure block 200′ is provided with at least two mounting holes 231. The piercing screw 500 is mounted in the mounting holes 231 of the support plate 230′. The tip of the piercing screw 500 protrudes from the support plate 230′ and is suitable for piercing the insulating coating on the surface of the upper pressure block 100′ and the profile 20 (see FIG1 ), thereby achieving electrical conduction between the profile, the pressure block assembly, and a bracket suitable for mounting a photovoltaic module. This conducts direct lightning and electrostatic induction that may act on the profile during thunderstorms to the bracket and then to the ground, thereby preventing damage to the photovoltaic equipment.
