[0024] When conventionally using a ruler to measure the distance between a cell or bus bar in a photovoltaic module and the edge of a glass plate, the distance between the cell or bus bar and the edge of the glass plate is generally achieved by aligning the zero-point scale line position on the ruler with the edge of the cell or bus bar through visual observation, and comparing the scale position of the edge of the glass plate on the ruler. Obviously, in this measurement method, the process of aligning the zero-point scale line position on the ruler with the edge of the cell or bus bar is not only cumbersome to operate, but also has relatively large errors, which increases the difficulty of measurement to a certain extent and reduces the measurement efficiency.

[0025] To this end, the present application provides a measuring ruler for a photovoltaic module.

[0026] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 3 As shown, Figure 1 A schematic diagram of the structure of a measuring ruler for a photovoltaic module provided in an embodiment of the present application; Figure 2 A schematic diagram of the ruler structure provided in an embodiment of the present application;

[0028] Figure 3 Another structural schematic diagram of a measuring ruler for a photovoltaic module provided in an embodiment of the present application.

[0029] In a specific embodiment of the present application, the measuring ruler for a photovoltaic module may include:

[0030] A main ruler 1 having a strip-shaped flat plate structure; wherein scale lines 11 are independently provided at both ends of the main ruler 1; and the zero point position of the scale line 11 is located at the end position of the main ruler 1;

[0031] Two sleeve rulers 2 are respectively sleeved on two ends of the main ruler 1; wherein the two sleeve rulers 2 can move along the main ruler 1.

[0032] like Figure 1 As shown, the shape and structure of the main ruler 1 in the present application are similar to that of a ruler, and the length of the main ruler 1 can be 100 mm to 110 mm, the width can be 20 mm to 22 mm, and the thickness can be 2 mm to 2.5 mm. The specific size structure can also be changed and adjusted based on the actual photovoltaic module model to be measured, and this is not specifically limited in the present application.

[0033] In addition, in this embodiment, independently readable scale lines 11 are respectively provided at both ends of the main scale 1, and a sleeve scale 2 is respectively provided at both ends of the main scale 1. The sleeve scale 2 is an annular structure, and its inner ring shape matches the cross-sectional shape of the main scale 1, so that the sleeve scale 2 can be sleeved on the main scale 1, and the sleeve scale 2 can slide along the length direction of the main scale 1, thereby changing the distance between the sleeve scale 2 and the zero point position in the corresponding scale line 11.

[0034] The length of the set ruler 2 along the direction perpendicular to the length of the main ruler 1 is approximately 25 mm to 30 mm, and the width along the length of the main ruler 1 is approximately 8 mm to 10 mm.

[0035] Therefore, when the measuring ruler is actually used to measure the distance between the battery cell or bus bar in the photovoltaic module and the edge position of the glass plate, the distance between the edge of the sleeve ruler 2 and the corresponding zero point position of the scale line 11 can be adjusted to be equal to the safety distance of the photovoltaic module of this model, and then the main ruler 1 is attached to the surface of the glass plate, and the sleeve ruler 2 is clamped at the edge position of the glass plate, without the need to align the zero point position of the scale line 11 on the main ruler 1 with the battery cell or bus bar in the photovoltaic module, thereby reducing the measurement difficulty; on this basis, it is observed whether the battery cell or bus bar falls between the zero point position on the scale line 11 and the sleeve ruler 2. If so, it means that the battery cell or bus bar is less than the safety distance to the edge position of the glass plate, and if not, it means that the battery cell or bus bar is not less than the safety distance to the edge position of the glass plate.

[0036] In addition, for each photovoltaic module, the safety distances corresponding to its long side and short side are not the same. Therefore, before measurement, the distance between the set ruler 2 at one end of the main ruler 1 and the zero point position of the corresponding scale line 11 can be adjusted to the long side safety distance of the photovoltaic module, and the distance between the set ruler 2 at the other end and the zero point position of the corresponding scale line 11 can be adjusted to the short side safety distance of the photovoltaic module; therefore, in the process of measuring photovoltaic modules of the same model, there is no need to adjust the positions of the set rulers 2 at both ends of the main ruler 1 multiple times, so as to achieve the measurement of the distances corresponding to the long side and short side of the same photovoltaic module. Compared with a measuring ruler with only one end that can be measured, the present embodiment simplifies the process of frequently adjusting the set ruler 2 to adapt to the different safety distances corresponding to the long side and short side of the photovoltaic module, thereby further simplifying the measurement difficulty of the photovoltaic module and improving the measurement efficiency of the photovoltaic module.

[0037] On this basis, in order to facilitate a more precise adjustment of the sliding position of the set ruler 2 on the main ruler 1, in another optional embodiment of the present application, the measuring ruler may further include:

[0038] A strip-shaped through-hole groove 12 is provided on the main ruler 1 along the length direction, wherein the groove wall of the through-hole groove 12 has a concave-convex structure;

[0039] The sleeve ruler 2 has a connecting column 21 located in the through hole groove 12, and the two ends of the connecting column 21 are respectively connected to the inner surfaces of the sleeve ruler 2 located on two different surfaces of the main ruler 1; the connecting column 21 is provided with a protruding elastic part 22 at the groove wall portion corresponding to the through hole groove 12.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, a through hole groove 12 is provided on the main scale 1, and the groove wall of the through hole groove 12 is a periodically distributed concave-convex structure; Figure 1 In the embodiment shown, the concave-convex structure is a sawtooth structure. In practical applications, a concave-convex structure in which a plurality of semicircular protrusions are arranged in sequence with a spacing can also be used. On this basis, a connecting column 21 is provided inside the ruler 2, and an elastic member 22 is provided on the connecting column 21. Specifically, a metal spring sheet, an elastic rubber member or other elastic structure can be used, and this application does not make specific restrictions on this.

[0041] In addition, the connecting column 21 on the set ruler 2 is arranged in the through hole groove 12, and the elastic member 22 connected to the connecting column 21 and the concavo-convex structure are against each other, so that when the set ruler 2 moves along the length direction of the main ruler 1, the connecting column 21 also slides and moves between the concavo-convex structures of the groove walls on both sides of the through hole groove 12, and at the same time, the elastic member 22 connected to the connecting column 21 can be deformed and fit the various protrusions and recesses of the concavo-convex structure in sequence. It can be seen that the groove wall with the concavo-convex structure in the through hole groove 12 on the main ruler 1 produces a certain resistance to the sliding movement of the set ruler 2 on the main ruler 1, so that the set ruler 2 can move only a very small spacing each time, that is, the spacing distance between two adjacent protrusions in the concavo-convex structure; thereby, the fine adjustment of the small spacing of the set ruler 2 on the main ruler 1 can be realized, avoiding the problem that the sliding distance of the set ruler 2 is too large, resulting in a large adjustment difficulty between the zero point position of the corresponding scale line 11.

[0042] In practical applications, the spacing between two adjacent protrusions in the concave-convex structure may be no greater than 0.5 mm, for example, 0.4 mm to 0.5 mm. It is sufficient to ensure the adjustment accuracy of the ruler 2 as much as possible.

[0043] like Figure 1 As shown, in Figure 1 In the illustrated embodiment, only one through hole slot 12 is provided at each end of the main ruler 1 for illustration. In another optional embodiment of the present application, the measuring ruler may further include:

[0044] Two through-hole slots 12 are arranged side by side at each end of the main ruler 1 along the length direction of the main ruler 1 ; and two connecting posts 21 are arranged on each sleeve ruler 2 and are respectively inserted into the two through-hole slots 12 .

[0045] In this embodiment, two through-hole grooves 12 arranged side by side are provided at each end of the main scale 1, and two connecting posts 21 are provided inside the sleeve scale 2, each connecting post 21 is provided in a through-hole groove 12, and the groove wall of each through-hole groove 12 is also provided with a concave-convex structure, and each connecting post 21 is provided with an elastic member 22 that abuts against the concave-convex structure on the groove wall of the through-hole groove 12. Therefore, when the sleeve scale 2 slides along the main scale 1, the concave-convex structures on the two through-hole grooves 12 can respectively apply relatively stacked resistance to the two connecting posts 21, thereby avoiding slight rotational movement of the sleeve scale 2 relative to the main scale 1 to a certain extent, thereby ensuring the accuracy of the movement of the sleeve scale 2 on the main scale 1.

[0046] In this embodiment, the connecting column 21, the elastic member 22, the through hole groove 12 and the concave-convex structure can be the same as those in the above embodiments, and will not be described in detail in this embodiment.

[0047] Based on the above discussion, the connection structure between the set ruler 2 and the main ruler 1 is not limited to Figure 1 and Figure 2 As shown in the implementation method. Figure 3 As shown, in another optional embodiment of the present application, the measuring ruler may further include:

[0048] A strip-shaped sawtooth structure 13 extending along the length direction of the main ruler 1 is provided on the surface of the main ruler 1 that fits the sleeve ruler 2;

[0049] A through hole is provided on the ruler sleeve 2, and a gear structure 24 is provided in the through hole and meshes with the strip-shaped sawtooth structure 13;

[0050] When the gear structure 24 is driven to roll, the gear structure 24 drives the sleeve ruler 2 to move along the length direction of the main ruler 1 .

[0051] like Figure 3 As shown, in Figure 3 In the illustrated embodiment, a sawtooth structure 13 is provided on the surface of the main scale 1, and a through hole is provided on the sleeve scale 2, and a gear structure 24 that can mesh with the sawtooth structure 13 is provided in the through hole. Both ends of the gear structure 24 are movably connected to the sleeve scale 2, so that the gear structure 24 can rotate around its rotation axis. Therefore, with the rotation of the gear structure 24, the gear structure 24 can roll along the extension direction of the sawtooth structure 13 and drive the sleeve scale 2 to move on the main scale 1. Therefore, in actual application, only the manual wave tooth structure 24 needs to roll on the sawtooth structure 13 to realize the movement of the sleeve scale 2 along the length direction of the main scale 1.

[0052] Based on the above discussion, in another optional embodiment of the present application, the measuring ruler may further include:

[0053] Screws 23 are provided on the sleeve ruler 2 at the side position corresponding to the main ruler 1 .

[0054] It should be noted that the hole for the screw 23 on the sleeve ruler 2 should be a through hole that penetrates the thickness direction of the sleeve ruler 2, so that when the screw 23 is screwed into the screw hole and tightened, the top of the screw 23 can abut against the surface of the main ruler 1, thereby limiting the relative movement between the main ruler 1 and the sleeve ruler 2. In the actual measurement process, the screw 23 can be loosened first, so that the top of the screw and the side of the main ruler 1 are separated from each other; the sleeve ruler 2 is controlled to slide along the main ruler 1, and when the sleeve ruler 2 slides to the required position on the main ruler 1, the screw 23 can be gradually tightened so that the top of the screw 23 is tightly against the side of the main ruler 1, thereby limiting the sliding of the sleeve ruler 2 relative to the main ruler 1, and the relative position between the sleeve ruler 2 and the main ruler 1 changes during the measurement process, thereby causing inaccurate measurement results.

[0055] Based on the above discussion, the main scale 1 in the measuring scale of the present application may include an aluminum alloy structure and a high temperature resistant nylon layer arranged on the outer surface of the aluminum alloy structure, and the cover scale 2 may be a high temperature resistant nylon cover scale.

[0056] In summary, the measuring ruler provided in the present application is provided with scale lines at both ends of the main ruler, and a sleeve ruler is provided at both ends respectively; therefore, when actually measuring the distance between the cell or bus bar of the photovoltaic module and the glass plate, the distance between the edge of the sleeve ruler and the 0-point position of the scale line on the main ruler can be adjusted to a safe distance first, and then the main ruler is attached to the surface of the glass plate, and the sleeve ruler is clamped on the edge of the glass plate, so as to compare and measure whether the distance between the cell or bus bar and the edge of the glass plate is greater than the safe distance, thereby simplifying the measurement difficulty; because the sleeve ruler is provided at both ends of the main ruler in the present application, when actually adjusting the distance between each sleeve ruler and the zero-point position of the corresponding scale line, one can be adjusted to the long side safe distance of the photovoltaic module, and the other can be adjusted to the short side safe distance of the photovoltaic module, thereby, when detecting the safety distances of two different sides of a single photovoltaic module, there is no need to repeatedly adjust the position of the sleeve ruler on the main ruler, thereby improving the measurement efficiency on the basis of reducing the measurement difficulty.
