Description

Press 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 photovoltaic 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 photovoltaic module with the profile to the bracket and to connect adjacent photovoltaic modules.

[0003] Currently, the common methods for mounting photovoltaic modules on brackets are to use a combination of clamps and bolts or to directly bolt the fixed side of the profile. The latter method is slow due to limited operating space, and in some cases, there is no operating space at all. Therefore, the combination of clamps and bolts is more commonly used. Specifically, the operator first assembles adjacent photovoltaic modules on the bracket using clamps, then passes bolts through the clamps between the adjacent modules and tightens them. Because the photovoltaic modules are already assembled, the operator can only tighten the bolts on the side of the photovoltaic module where the clamps are installed (called the fixed side) by crossing the photovoltaic module from the side without the clamps (called the free side). However, with the increasing market demand for photovoltaic modules, larger photovoltaic modules are becoming increasingly popular, with some modules reaching as wide as 1.3 meters. This makes it difficult for operators to tighten bolts on the fixed side far from their own reach. Some even kneel down to press the photovoltaic module, increasing the risk of hidden cracks in the module.

[0004] Summary of the Invention

[0013] In one embodiment of the present invention, when the length of the second protrusion in the first direction is less than the length of the third protrusion, the clamping plate has an upper flange at the edge away from the limiting plate, and a clamping groove is formed between the upper flange and the clamping plate, and the clamping groove is suitable for sliding into a fixed plate connected to the second profile.

[0014] In one embodiment of the present invention, when the upper pressure block further includes a first pressure foot and a second pressure foot, in the second direction: there is a first distance L1 between the end of the lower notch of the side groove of the profile away from the fixing part and the end of the fixing part away from the side groove; there is a second distance L2 between the side of the second pressure foot close to the base plate and the side of the second pressure foot away from the base plate; there is a third distance L3 between the edge of the clamping plate away from the limiting plate and the edge of the clamping plate close to the limiting plate; there is a fourth distance L4 between the edge of the upper flange close to the limiting plate and the edge of the upper flange away from the limiting plate; the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 satisfy: 0<L3-L1-L2<L4.

There is no need for the staff to lock the compression block assembly far away from them, which reduces the difficulty of installation.

[0044] Example 1

[0045] Figure 1 is a front view of a profile of the present application, Figure 2 is a perspective exploded schematic diagram of a pressing block assembly of Example 1 of the present application, Figure 3 is a cross-sectional view of an upper pressing block of Example 1 of the present application, Figure 4 is a perspective schematic diagram of a lower pressing block of Example 1 of the present application, and Figure 5 is a cross-sectional view of a lower pressing block of Example 1 of the present application. With reference to Figures 1-5, the present invention provides a pressing block assembly 10 suitable for combining and fixing two adjacent profiles 20 of a photovoltaic module, the profile 20 having a side groove 21 and a fixing plate 22, and the pressing block assembly 10 includes an upper pressing block 100 as shown in Figure 3 and a lower pressing block 200 as shown in Figures 4-5. In the preferred embodiment as shown in Figure 1, the side groove 21 of the profile 20 also has relatively protruding upper notches 23 and lower notches 24.

[0046] First, the structure of the upper pressing block 100 and its cooperation with the profile 20 are described as follows with reference to Figures 1-3:

[0047] The upper pressing block 100 includes a top plate 110, a bottom plate 120, and a first side plate 130 and a second side plate 140 located opposite each other between the top plate 110 and the bottom plate 120. The first side plate 130 has a first ridge 131 protruding along the positive direction AA' of the first direction at an edge close to the top plate 110 (the upper edge as shown in FIG3 ). The first side plate 130 also has a second ridge 132 protruding along the opposite direction A'A of the first direction at an edge close to the bottom plate 120 (the lower edge as shown in FIG3 ). The second side plate 140 has a third ridge 141 protruding along the positive direction BB' of the second direction at a position close to the bottom plate 120. Furthermore, unlike the first ridges 131 and the second ridges 132, the first ridges 131 and the second ridges 132 extend only in the positive direction AA' or the reverse direction A'A of the first direction, and form grooves with other structural parts of the upper pressing block 100 in the second direction so as to achieve hook connection, while the third ridge 141 itself is more obviously hook-shaped than the second side surface 140, and after protruding a certain length in the positive direction BB' of the second direction, it also protrudes in the reverse direction A'A of the first direction.

[0048] When the upper pressing block 100 is simultaneously engaged with two adjacent profiles 20 (see Figure 8 ), the two adjacent profiles 20 are designated as the first profile 20a and the second profile 20b for ease of understanding. To achieve the technical effect of quick assembly, the left and right sides of the upper pressing block 100 in the pressing block assembly 10 provided by the present invention do not fully clamp the corresponding profile 20a or 20b simultaneously. In the first embodiment, the length of the second ridge 132 in the first direction AA' is less than the length of the third ridge 141, meaning that the second ridge 132's tightening effect on the corresponding profile 20 is weaker than the tightening effect of the third ridge 141 on the other profile 20.

[0049] Specifically, the first protrusion 131 of the upper pressing block 100 is adapted to pass over the upper notch 23a of the first profile 20a and hook onto the top of the side groove 21a. The second protrusion 132 is adapted to approach (but not contact) the bottom of the side groove 21a of the first profile 20a. The third protrusion 141 is adapted to pass over the lower notch 24b of the second profile 20b and hook onto the bottom of the side groove 21b. It should be noted that the term "hooked onto" does not necessarily mean close contact, but rather refers to a stronger degree of fastening than "approaching."

[0050] Furthermore, to enhance the fastening effect, the upper pressing block 100 in this embodiment further includes a fourth protrusion 111 extending along the positive direction AA' of the first direction at a position on the top plate 110 near the first side plate 130. A first groove 112 is formed between the fourth protrusion 111 and the first protrusion 131. When the upper pressing block 100 and the first profile 20a are engaged, that is, when the first protrusion 131 is hooked onto the top of the side groove 21a, the upper notch 23a of the side groove 21a is located in the first groove 112.

[0051] The structure of the lower pressing block 200 and its cooperation with the profile 20 are described as follows with reference to Figures 1-2 and 4-5:

[0052] The lower pressing block 200 has a limiting plate 210 and a supporting plate 220 and a clamping plate 230 respectively located on the first side and the second side of the limiting plate 210, wherein the limiting plate 210 is suitable for limiting the upper pressing block 100 and the two adjacent profiles 20, and the upper surface of the limiting plate 210 is suitable for conforming to the lower surface of the bottom plate 120 of the upper pressing block 100, and the edge of the clamping plate 230 away from the limiting plate 210 has a clamping portion 231, and the clamping portion 231 is suitable for cooperating with the fixing plate 22b of the second profile 20b.

[0053] In this embodiment, the upper surface of the limiting plate 210 is higher than the two sides in the first direction AA'. Correspondingly, the upper pressing block 100 has a first presser foot 121 and a second presser foot 122 at the position of the bottom plate 120 near the first side plate 130 and the second side plate 140. The first presser foot 121 is suitable for contacting the edge of the supporting plate 220 near the limiting plate 210 (the right edge as shown in Figure 5), and the second presser foot 122 is suitable for contacting the edge of the clamping plate 230 near the limiting plate 210 (the left edge as shown in Figure 5), thereby playing a limiting role. It is understandable that in some other embodiments, the upper surface of the limiting plate 210 can also be lower than the two sides in the first direction AA' or be provided with grooves, ridges, etc., and the lower surface of the upper pressing block 100 only needs to be provided with a corresponding structure that can be matched with it. This application does not make specific restrictions here.

[0054] In the clamping block assembly 100 provided in Example 1, the clamping portion 231 includes an upper flange 232 located at the edge of the clamping plate 230 away from the limiting plate 210, and a clamping groove 233 is formed between the upper flange 232 and the clamping plate 230, and the clamping groove 233 is suitable for sliding into the fixing plate 22b connected to the second profile 20b.

[0055] Furthermore, in this embodiment, the upper pressing block 100 further includes a first fastening hole 113 extending through the top plate 110 and a second fastening hole 123 extending through the bottom plate 120, and the lower pressing block 200 further includes a third fastening hole 211 extending through the limiting plate 210. When the upper pressing block 100 and the lower pressing block 200 are engaged, the first fastening hole 113, the second fastening hole 123, and the third fastening hole 211 are opposed to each other in the first direction AA'. The pressing block assembly 10 further includes a fastener 300 adapted to pass through the first fastening hole 113, the second fastening hole 123, and the third fastening hole 211, thereby securing the upper pressing block 100 and the lower pressing block 200 to the bracket.

[0056] FIG6 is a front view of a puncture screw according to the first embodiment of the present application. Furthermore, in this embodiment, the pressing block assembly 10 further includes a plurality of puncture screws 400. The support plate 220 and the clip plate 230 of the lower pressing block 200 are each provided with at least two mounting holes 401 suitable for mounting the puncture screws 400. The tip 402 of each puncture screw 400 is adapted to protrude from the support plate 220 and the clip plate 230. Specifically, the tip 402 of at least one of the plurality of puncture screws 400 located on the support plate 220 protrudes from the upper surface of the support plate 220, and the tip 402 of at least one of the plurality of puncture screws 400 protrudes from the lower surface of the support plate 220. Similarly, the tip 402 of at least one of the plurality of puncture screws 400 located on the clip plate 230 protrudes from the upper surface of the clip plate 230, and the tip 402 of at least one of the plurality of puncture screws 400 protrudes from the lower surface of the clip plate 230. The piercing screw 400 is suitable for piercing the insulating coating on the profile 20 (as shown in reference Figure 1) and the surface of the bracket at the same time, thereby realizing current conduction between the profile, the pressure block assembly and the bracket suitable for installing the photovoltaic module, and transmitting the direct lightning and electrostatic induction that may act on the profile during lightning weather to the bracket and then to the ground, thereby avoiding damage to the photovoltaic equipment.

[0057] Figures 7-8 are schematic diagrams of the installation of a pressing block assembly according to the first embodiment of the present application. In conjunction with Figures 1-8, the present invention also provides a method for installing the pressing block assembly, comprising the following steps:

[0058] (1) Place the lower pressing block 200 on the bracket 30, and place the second volt assembly 40b with the second profile 20b installed on the edge on the clamping plate 230 of the lower pressing block 200, and slide the fixing plate 22b of the second profile 20b into the clamping groove 233 of the lower pressing block 200.

[0059] (2) Place the upper pressing block 100 on the limiting plate 210 of the lower pressing block 200 so that the upper pressing block 100 and the second profile 20b are matched. In this embodiment, the third protrusion 141 of the upper pressing block 100 is suitable for hooking to the bottom of the side groove 21b of the second profile 20b, and the upper edge of the second side plate 140 of the upper pressing block 100 is not provided with a fastening structure. Therefore, the upper pressing block 100 can be directly translated along the positive direction BB' of the second direction, and then translated along the reverse direction A'A of the first direction until the matching is completed. After the upper pressing block 100 is placed, the fastener 300 can be locked without affecting the subsequent installation of the adjacent first profile 20a.

[0060] (3) The first photovoltaic component 40a with the first profile 20a installed on the edge is placed obliquely on the supporting plate 220 of the lower pressing block 200, so that the upper notch 23a of the side groove is stuck in the first groove 112 and the first protrusion 131 is hooked to the top of the side groove 21a. Then the first photovoltaic component 40a is leveled. Under the action of gravity, the bottom of the side groove 21a of the first profile 20a will complete the cooperation with the second protrusion 132, and the cooperation between the first photovoltaic component 20a and the upper pressing block 100 is completed.

[0061] It is understandable that since the upper notch 23a of the first profile 20a is not fixed, in order to ensure that the first profile 20a will not easily fall out after installation, the pressing block assembly 10 and the profile 20 in this embodiment also need to meet the following conditions:

[0062] In the second direction BB': there is a first distance L1 between the end of the lower notch 24 of the side groove 21 of the profile 20 away from the fixing part 22 and the end of the fixing part 22 away from the side groove 21; there is a second distance L2 between the side of the second presser foot 122 close to the bottom plate 120 and the side of the second presser foot 122 away from the bottom plate 120; there is a third distance L3 between the edge of the clamping plate 230 away from the limiting plate 210 and the edge of the clamping plate 230 close to the limiting plate 210; there is a fourth distance L4 between the edge of the upper flange 232 close to the limiting plate 210 and the edge of the upper flange 232 away from the limiting plate 210; the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 satisfy: 0<L3-L1-L2<L4.

[0063] Figures 9-10 are schematic diagrams illustrating the disassembly of a pressure block assembly according to Example 1 of the present application. To disassemble a pressure block assembly 10, it is necessary to first remove all fasteners 300 of the pressure block assembly 10 surrounding the two adjacent profiles 20a and 20b to which the pressure block assembly 10 is secured. The lower pressure block 200 is then translated and slid out in a direction B'B opposite to the second direction, allowing the fixing plate 22b of the second profile 20b to slide out of the clamping groove 233. The upper pressure block 100 can then be removed by lifting the portions of the two adjacent profiles 20 adjacent to the pressure block assembly 10.

[0064] It is understandable that after the upper pressing block is disassembled, the photovoltaic module loses its fixation and can be easily disassembled and replaced.

[0068] Unlike the first embodiment, the length of the second ridge 132 in the first direction AA' in this embodiment is greater than the length of the third ridge 141. That is, the second ridge 132 has a stronger tightening effect on the first profile 20a than the third ridge 141 has on the second profile 20b. Specifically, the first ridge 131' of the upper pressing block 100' is adapted to pass over the upper notch 23a of the first profile 20a and hook onto the top of the side groove 21a. The second ridge 132' is adapted to pass over the lower notch 24a of the first profile 20a and hook onto the bottom of the side groove 21a of the first profile 20a (without contact). The third ridge 141' is adapted to be close to the bottom of the side groove 21b. It should be noted that the term "hooked onto" here does not necessarily mean close contact, but rather refers to a stronger tightening effect than "close to."

[0069] Furthermore, in this embodiment, the clamping portion 231' includes a clamping protrusion 232' located at the edge of the clamping plate 230' away from the limiting plate 210', and the edge of the clamping protrusion 232' away from the clamping plate 230' (such as the upper edge in Figure 14) has a flange 233' protruding in the opposite direction B'B of the second direction, which is suitable for clamping the fixing plate 22b of the second profile 20b.

[0070] Figures 15-16 are schematic diagrams of the installation of a pressure block assembly according to the second embodiment of the present application. Referring to Figures 1 and 11-16, the installation method of the pressure block assembly 10' in this embodiment includes the following steps:

[0071] (1) The lower pressing block 200 ′ is placed on the bracket 30 , and the first photovoltaic assembly 40 a with the first profile 20 a mounted on the edge is placed on the supporting plate 220 ′ of the lower pressing block 200 ′.

[0072] (2) Install the upper pressing block 100' at an angle into the side groove 21a of the first profile 20a, hooking the first protrusion 131' to the top of the side groove 21a. Then, lay the upper pressing block 100' flat, hooking the second protrusion 132' to the bottom of the side groove 21a. The lower surface of the bottom plate 120' of the upper pressing block 100' and the upper surface of the limit plate 210' of the lower pressing block 200' are in a form-fitting manner. Once the upper pressing block 100' is in place, the fastener 300' can be tightened without affecting the subsequent installation of the adjacent second profile 20b.

[0073] (3) The second photovoltaic module 40b with the second profile 20b installed on the edge is placed obliquely on the clamping plate 230' of the lower pressing block 200' and then laid flat. Under the action of gravity or a small amount of pressure, the bottom of the side groove 21b of the second profile 20b will complete the cooperation with the third protrusion 141'. The third protrusion 141' is close to the bottom of the side groove 21b, and the fixing plate 22b is clamped into the flange 233'. The second photovoltaic module 20b is completed with the upper pressing block 100' and the lower pressing block 200'.

[0074] It is understandable that, since the upper notch 23b of the second profile 20b is not fixed, in order to ensure that the second profile 20b does not easily fall out after installation, the pressing block assembly 10 and the profile 20 in this embodiment also need to meet the following conditions:

[0075] In the second direction BB': there is a first distance L1 between the end of the lower notch 24 of the side groove 21 of the profile 20 away from the fixing part 22 and the end of the fixing part 22 away from the side groove 21; there is a second distance L2 between the side of the second presser foot 122' close to the bottom plate 120' and the side of the second presser foot 122' away from the bottom plate 120'; there is a third distance L3 between the edge of the clamping plate 230' away from the limiting plate 210' and the edge of the clamping plate 230' close to the limiting plate 210'; there is a fourth distance L4 between the edge of the flange 233' close to the limiting plate 210' and the side of the flange 233' away from the limiting plate 210'; the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 satisfy: 0<L3-L1-L2<L4.

[0076] Figures 17-18 are schematic diagrams illustrating the disassembly of a pressure block assembly according to Example 2 of the present application. To disassemble a pressure block assembly 10', it is necessary to first remove all fasteners 300' of the pressure block assembly 10' surrounding the two adjacent profiles 20a and 20b to which the pressure block assembly 10' is fixed. The lower pressure block 200' is then translated and slid out in a direction B'B opposite to the second direction, allowing the fixing plate 22b of the second profile 20b to slide out from the flange 233'. The upper pressure block 100' can then be tilted and removed by lifting the portions of the two adjacent profiles 20a and 20b adjacent to the pressure block assembly 10'.

[0077] It is understandable that after the upper pressing block is disassembled, the photovoltaic module loses its fixation and can be easily disassembled and replaced.

[0078] 7-8, 15-16, the present invention further provides a photovoltaic system, comprising: a plurality of photovoltaic components 40a, 40b, each photovoltaic component 40a, 40b having a profile 20a, 20b installed on the edge, the profile 20a, 20b having a side groove 21a, 21b and a fixing plate 22a, 22b; a bracket 30, suitable for carrying the plurality of photovoltaic components 40a, 40b; and a plurality of pressing block assemblies 10, 10' as in any of the previous embodiments, suitable for cooperating with the side grooves 21a, 21b and the fixing plates 22a, 22b to fix the profile 20a, 20b, so that the plurality of photovoltaic components 40a, 40b are fixedly mounted on the bracket 30.
