Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a limiting device for the end of a photovoltaic module for horizontal installation. Background Technology

[0002] Currently, photovoltaic (PV) modules are installed longitudinally, meaning the length of the PV module runs vertically up and down along the sloping top of the PV support. While this method simplifies the PV support structure, it requires at least four sets of fittings and bolts to secure each PV module. Furthermore, because the top of the support is sloping, someone needs to hold the PV module in place to prevent slippage, and another person is needed to install the fittings and bolts. Installing a single PV module requires multiple people, making large-area PV module installations labor-intensive. Therefore, we propose a transverse PV module installation scheme to reduce labor and improve installation efficiency. This scheme involves the limitation and fixation of PV modules at both ends of the PV support beam. Therefore, we designed a transverse PV module end-limiting device according to this application, used in conjunction with the beam in the transverse PV module installation scheme, to limit the position of one side of the PV modules located at both ends of the beam. Utility Model Content

[0003] The technical problem to be solved by this utility model is to solve the problems existing in the background art and provide a photovoltaic module horizontal arrangement installation end limiting device, wherein the first locking plate and the second locking plate are used to install and fix to the crossbeam, and the limiting member limits one side of the photovoltaic module located at both ends of the crossbeam.

[0004] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: a photovoltaic module horizontally arranged installation end limiting device, including a first locking plate, a second locking plate, and a limiting member. The second locking plate is used to be installed below the first locking plate. The second locking plate is connected to the first locking plate by a first screw. One end of the first locking plate is provided with an upwardly extending support plate. A second screw is horizontally screwed onto the support plate. The limiting member is movably installed on the threaded end of the second screw. The limiting member is used to limit the photovoltaic module installed on the crossbeam.

[0005] The first locking plate has at least one first threaded hole on its axis, and the second locking plate has a through hole on its axis. The threaded end of the first screw passes through the through hole and is screwed into the first threaded hole.

[0006] The support plate is provided with at least one second threaded hole, and the second screw is screwed into the second threaded hole. The threaded end of the second screw is located on the upper side of the first locking plate. The lower side of the first locking plate is also provided with two limiting grooves, and the first screw is connected to the first locking plate at the position between the two limiting grooves.

[0007] The two side walls of the limiting groove are outwardly inclined slopes.

[0008] The bottom of the limiting groove is provided with protrusions to increase friction.

[0009] A first boss is provided axially at the lower center of the first locking plate.

[0010] A second boss is provided axially at the upper center of the second locking plate.

[0011] The limiting component includes an L-shaped block, one side of which is rotatably connected to the threaded end of the second screw.

[0012] A cylinder is fixed to one side of the L-shaped block, and the cylinder is movably fitted onto the threaded end of the second screw.

[0013] Compared with the prior art, the present utility model adopting the above technical solution has the following characteristics: 1. The first and second locking plates of this utility model are fixed to the crossbeam by a first screw. Specifically, the first locking plate is inserted into the cavity of the crossbeam, and the second locking plate is located on the lower side of the crossbeam. The bottom of the crossbeam has a continuous notch. The threaded end of the first screw passes through the second locking plate and the notch, and is screwed and fixed to the first locking plate. A support plate is located at the end of the crossbeam, and the second screw is screwed onto the support plate. A limiting member is movably installed on the threaded end of the second screw. When the second screw is turned, the limiting member does not rotate with the second screw, thus limiting the position of the photovoltaic modules located at both ends of the crossbeam.

[0014] 2. This utility model uses a limiting groove to position the first locking plate. The two side walls of the limiting groove are outwardly inclined slopes, which facilitates the limiting groove to engage with the reinforcing part of the crossbeam. When there is an error in the distance between the reinforcing parts on both sides of the bottom notch of the crossbeam, the slopes on both sides of the limiting groove make the limiting groove flared, thereby guiding the reinforcing parts on both sides into the limiting groove.

[0015] 3. The bottom of the limiting groove of this utility model is provided with a protrusion to increase the friction between the first locking plate and the crossbeam.

[0016] 4. The first protrusion in this utility model not only increases the thickness of the first locking plate, but also facilitates the positioning of the first locking plate and the crossbeam.

[0017] 5. The second protrusion in this utility model not only increases the thickness of the second protrusion, but also facilitates the positioning of the second locking plate and the crossbeam. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0031] Example 1: See Figure 1-7 A photovoltaic module horizontally arranged installation end limiting device includes a first locking plate 10, a second locking plate 20, and a limiting member 50. The second locking plate 20 is used to be installed below the first locking plate 10. The second locking plate 20 is connected to the first locking plate 10 by a first screw 30. One end of the first locking plate 10 is provided with an upwardly extending support plate 11. A second screw 40 is horizontally screwed onto the support plate 11. The limiting member 50 is movably installed on the threaded end of the second screw 40. The limiting member 50 is used to limit the photovoltaic module 2 installed on the crossbeam 1.

[0032] During installation, please refer to Figure 8 , 9 The first locking plate 10 and the second locking plate 20 are fixed to the crossbeam 1 by the first screw 30. Specifically, the first locking plate 10 is inserted into the cavity of the crossbeam 1, and the second locking plate 20 is located on the lower side of the crossbeam 1. The bottom of the crossbeam 1 has a continuous notch. The threaded end of the first screw 30 passes through the second locking plate 20 and the notch, and is screwed and fixed to the first locking plate 10. The support plate 11 is located at the end of the crossbeam 1, and the second screw 40 is screwed onto the support plate 11. The limiting member 50 is movably installed on the threaded end of the second screw 40. When the second screw 40 is turned, the limiting member 50 does not rotate with the second screw 40. The limiting member 50 limits the photovoltaic module 2 located at both ends of the crossbeam 1 on one side. Figure 9 As shown.

[0033] In this embodiment, see Figure 4 , 56. Two first threaded holes 16 are provided on the axis of the first locking plate 10, and a through hole 22 is provided on the axis of the second locking plate 20. The threaded end of the first screw 30 passes through the through hole 22 and is screwed into the first threaded hole 16.

[0034] The support plate 11 is provided with a second threaded hole 17. There may be one or two second threaded holes 17. A second screw 40 is screwed onto the second threaded hole 17. The threaded end of the second screw 40 is located on the upper side of the first locking plate 10. Example 2: Based on Example 1, see Figure 5 , 6 The lower side of the first locking plate 10 is also provided with two limiting grooves 12, and the first screw 30 is connected to the first locking plate 10 at the position between the two limiting grooves 12. The installation position of the first locking plate 10 is positioned by the limiting grooves 12.

[0035] During installation, the two limiting grooves 12 are used to engage with the reinforcing parts that protrude upwards on both sides of the bottom notch of the crossbeam 1.

[0036] Further, see Figure 5 The two side walls of the limiting groove 12 are outwardly inclined slopes 13, which facilitates the limiting groove 12 to be engaged with the reinforcing part of the crossbeam 1. When there is an error in the distance between the reinforcing parts on both sides of the bottom notch of the crossbeam 1, the slopes 13 on both sides of the limiting groove 12 make the limiting groove 12 into a funnel shape, thereby guiding the reinforcing parts on both sides into the limiting groove 12.

[0037] Further, see Figure 6 The bottom of the limiting groove 12 is provided with a protrusion 15 to increase friction.

[0038] In this embodiment, the protrusion 15 adopts a triangular block structure. During installation, the pointed part on the lower side of the triangular block can be embedded into the reinforcing part that protrudes upward on both sides of the bottom notch of the crossbeam 1.

[0039] Example 3: Based on Example 1 or Example 2, see Figure 2 , 5 A first boss 14 is provided axially at the lower center of the first locking plate 10. The first boss 14 not only increases the thickness of the first locking plate 10, but also facilitates the positioning of the first locking plate 10 with the crossbeam 1.

[0040] Furthermore, a second boss 21 is provided axially at the upper center of the second locking plate 20. The provision of the second boss 21 not only increases the thickness of the second boss 21, but also facilitates the positioning of the second locking plate 20 and the crossbeam 1.

[0041] Example 4: Based on Example 1, Example 2, or Example 3, see [link to example]. Figure 7 The limiting member 50 includes an L-shaped block 51, one side of which is rotatably connected to the threaded end of the second screw 40. In this configuration, the threaded end of the second screw 40 can have a protrusion with a diameter smaller than that of the second screw 40, and a limiting hole is provided on one side of the L-shaped block 51, into which the protrusion passes.

[0042] In this embodiment, see Figure 3 , 7 A cylinder 52 is fixed on one side of the L-shaped block 51, and the cylinder 52 is movably fitted onto the threaded end of the second screw 40.

[0043] The usage process or principle of this utility model: During installation, please refer to Figure 8 , 9 The first locking plate 10 and the second locking plate 20 are installed and fixed to the crossbeam 1 by the first screw 30. The first locking plate 10 is used to insert into the cavity of the crossbeam 1, and the second locking plate 20 is located on the lower side of the crossbeam 1. The bottom of the crossbeam 1 has a continuous notch. After the threaded end of the first screw 30 passes through the second locking plate 20 and the notch, it is screwed and fixed to the first locking plate 10.

[0044] The support plate 11 is located at the end of the crossbeam 1. The second screw 40 is screwed onto the support plate 11. The limiting member 50 is movably installed on the threaded end of the second screw 40. When the second screw 40 is tightened, the limiting member 50 does not rotate with the second screw 40. The limiting member 50 limits one side of the photovoltaic module 2 located at both ends of the crossbeam 1. Figure 9 As shown.
