Description

Technical Field

[0001] This application relates to the technical field of photovoltaic module testing, and particularly to a testing bracket and a testing system. Background Art

[0002] With the development of the solar photovoltaic industry, there are more and more photovoltaic power stations. After production, the photovoltaic modules in a photovoltaic power station generally need to undergo a sand pressure test. The sand pressure test refers to simulating the wind load and snow load conditions in the form of static sand pressure to test the bearing capacity of the photovoltaic module. In the sand pressure test of the photovoltaic module, generally two testing brackets and a main beam are required. The two testing brackets support the two ends of the main beam, and the photovoltaic module is installed on the main beam.

[0003] There are various main beams with different cross-sectional shapes in the sand pressure test. To improve the utilization rate of the testing bracket, the same testing bracket can generally be applicable to various main beams with different cross-sectional shapes. However, in the related art, when replacing the main beam with a different cross-sectional shape, the operation is cumbersome, which affects the replacement efficiency. Utility Model Content

[0004] This application provides a testing bracket and a testing system to solve the technical problem that in the related art, when replacing the main beam with a different cross-sectional shape, the operation is cumbersome and affects the replacement efficiency.

[0005] To solve the above problems, this application provides a testing bracket, which includes:

[0006] A base frame having a guiding connection part and a first installation groove, and the first installation groove has a notch;

[0007] A cushion block detachably arranged in the first installation groove. The cushion block has a second installation groove. When the cushion block is installed in the first installation groove, the second installation groove is located on the side of the cushion block facing the notch, and the cross-sectional shape of the second installation groove is different from that of the first installation groove;

[0008] A pressing block movably arranged along the guiding connection part on one side of the notch for fixing the main beam in the first installation groove or the second installation groove.

[0009] In some embodiments, the guiding connection part is a threaded rod, and the testing bracket further includes a locking nut. The locking nut provides a pressing force for the pressing block by cooperating with the threaded rod to fix the main beam in the first installation groove or the second installation groove.

[0010] In some embodiments, at least two threaded rods are provided and distributed on opposite sides of the pressing block;

[0011] The base frame further has a mounting platform and a mounting seat body disposed on the mounting platform. Each threaded rod corresponds to one of the mounting seat bodies, and the two opposite mounting seat bodies and the mounting platform form the first mounting groove.

[0012] In some embodiments, the cushion block is detachably disposed between the two opposite mounting seat bodies. The mounting seat body has a guiding groove, and the cushion block has a guiding protrusion that cooperates with the guiding groove.

[0013] In some embodiments, the mounting seat body has a first opening groove. The openings of the first opening grooves on the two opposite sides of the first mounting groove are arranged in opposite directions. The threaded rod is rotatably disposed in the first opening groove around a direction perpendicular to the central axis of the threaded rod.

[0014] In some embodiments, the threaded rod has a limiting surface that cooperates with the first opening groove, and the limiting surface is used to limit the rotation of the threaded rod around its central axis.

[0015] In some embodiments, both opposite sides of the pressing block are provided with second opening grooves. The openings of the second opening grooves on the two opposite sides are arranged in opposite directions. The pressing block cooperates with the threaded rod through the second opening grooves, and the openings of the second opening grooves are used to enable the threaded rod to disengage from the second opening grooves when rotating.

[0016] In some embodiments, the second mounting groove has opposite first inclined side walls and second inclined side walls, and both the first inclined side walls and the second inclined side walls have anti-slip structures.

[0017] In some embodiments, the test bracket further includes:

[0018] A handling handle, disposed on the base frame.

[0019] This application further provides a test system. The test system includes a main beam and the test bracket assembly as described above. Two of the test brackets in the test bracket assembly support the two ends of the main beam.

[0020] The beneficial effects of the embodiments of the present application are as follows: The test bracket provided by the present application includes a base frame, a cushion block, and a pressing block. Among them, the base frame has a guiding connection part and a first installation groove, and the first installation groove has a notch; the cushion block has a second installation groove, and the cross-sectional shape of the second installation groove is different from that of the first installation groove. By detachably arranging the cushion block in the first installation groove, and when the cushion block is installed in the first installation groove, the second installation groove is located on the side of the cushion block facing the notch, the test bracket can be applicable to main beams with different cross-sectional shapes. The pressing block is used to fix the main beam in the first installation groove or the second installation groove. By movably arranging the pressing block along the guiding connection part on one side of the notch, the pressing block can be moved up and down along the guiding connection part to press the main beam tightly or loosen the main beam so that the main beam can be disassembled. At the same time, when the pressing block moves upward to loosen the main beam, after the main beam is disassembled, the disassembly and installation of the cushion block can also be realized. During the replacement process of main beams with different cross-sectional shapes, there is no need to completely disassemble the pressing block and then reinstall it, which simplifies the replacement operation of the main beam and improves the replacement efficiency.

[0021] When the guiding connection part on the base frame is a threaded rod, the test bracket further includes a locking nut that cooperates with the threaded rod. The locking nut provides a pressing force for the pressing block by cooperating with the threaded rod. By rotating the locking nut and adjusting the position of the locking nut on the threaded rod, the pressing block can be used to press the main beam tightly or loosen the main beam, and the operation is simple and fast.

[0022] When the cushion block is detachably arranged between two opposite mounting seat bodies, by providing guiding grooves on the mounting seat bodies and guiding protrusions on the cushion block that cooperate with the guiding grooves, the cushion block can be accurately and quickly installed in place when installing the cushion block.

[0040] Please refer toFigures 1 to 3 , this application provides a test bracket 100, which can be applied to the test system of the photovoltaic module 300 to support and install the main beam 200 of the photovoltaic module 300. It can be understood that when the test bracket 100 is used to support the main beam 200, two test brackets 100 are provided, and the two ends of the main beam 200 are arranged on the test brackets 100, so as to realize the support of the test bracket 100 for the main beam 200. Then, the photovoltaic module 300 to be tested is arranged on the main beam 200, and sandbags 400 are placed on the photovoltaic module 300, so that the sand pressure test can be carried out on the photovoltaic module 300.

[0041] The test bracket 100 provided by this application includes a base frame 10, a cushion block 20 and a pressing block 30. The base frame 10 has a guiding connection part and a first installation groove 11, and the first installation groove 11 has a notch 111. The cushion block 20 is detachably arranged in the first installation groove 11. The cushion block 20 has a second installation groove 21, and the cross-sectional shape of the second installation groove 21 is different from the cross-sectional shape of the first installation groove 11. When the cushion block 20 is installed in the first installation groove 11, the second installation groove 21 is located on the side of the cushion block 20 facing the notch 111 of the first installation groove 11. The pressing block 30 is movably arranged along the guiding connection part on one side of the notch 111 for fixing the main beam 200 in the first installation groove 11 or the second installation groove 21. Wherein, the cross-sectional shape of the first installation groove 11 refers to the cross-sectional shape perpendicular to the extending direction of the first installation groove 11, and the cross-sectional shape of the second installation groove 21 refers to the cross-sectional shape perpendicular to the extending direction of the second installation groove 21. It can be understood that the extending direction of the first installation groove 11 is the central axis direction of the main beam 200 when the main beam 200 is matched with the first installation groove 11, and the extending direction of the second installation groove 21 is the central axis direction of the main beam 200 when the main beam 200 is matched with the second installation groove 21.

[0042] It should be noted that the first installation groove 11 has a notch 111, the cushion block 20 is detachably arranged in the first installation groove 11, and when the cushion block 20 is installed in the first installation groove 11, the second installation groove 21 of the cushion block 20 is located on the side of the cushion block 20 facing the notch 111 of the first installation groove 11. Therefore, when the cushion block 20 is installed in the first installation groove 11, the notch 111 of the first installation groove 11 can also be the notch 111 of the second installation groove 21. Therefore, by movably arranging the pressing block 30 along the guiding connection part on one side of the notch 111, the main beam 200 can be fixed in the first installation groove 11 or the second installation groove 21 when the pressing block 30 is moved downward.

[0043] It can be understood that, among them, fixing the main beam 200 to the first installation groove 11 by the pressing block 30 means that when the test bracket 100 needs to install the main beam 200 suitable for the cross-sectional shape of the first installation groove 11, the cushion block 20 is removed from the first installation groove 11, the main beam 200 is directly embedded in the first installation groove 11, and then the pressing block 30 slides down to compress the main beam 200 so as to fix the main beam 200 in the first installation groove 11; fixing the main beam 200 to the second installation groove 21 by the pressing block 30 means that when the test bracket 100 needs to install the main beam 200 suitable for the cross-sectional shape of the second installation groove 21, the cushion block 20 is installed in the first installation groove 11. For example, it can be installed at the bottom of the first installation groove 11, but not limited to this. At this time, the main beam 200 can be installed in the second installation groove 21 of the cushion block 20, and then the pressing block 30 slides down to compress the main beam 200 so as to fix the main beam 200 in the second installation groove 21, that is, fix the main beam 200 between the pressing block 30 and the cushion block 20. Among them, the cross-sectional shape of the main beam 200 suitable for the first installation groove 11 or the cross-sectional shape of the main beam 200 suitable for the second installation groove 21 does not mean that the cross-sectional shape of the main beam 200 must be exactly the same as the cross-sectional shape of the first installation groove 11 or the second installation groove 21. For example, an arc-shaped groove can install a main beam 200 with a circular or D-shaped cross-section; a V-shaped groove can install a main beam 200 with a triangular, circular, D-shaped, regular hexagon or regular octagon cross-section; a trapezoidal groove can install a main beam 200 with a circular, D-shaped, regular hexagon or regular octagon cross-section, as Figures 8 to 10 shown.

[0044] The base frame 10 has a first installation groove 11 and a guiding connection part. The specific shape and structure of the base frame 10 in the embodiments of the present application are not limited. For example, as Figure 3As shown, in some embodiments, the base frame 10 forms an installation platform 14, and the first installation groove 11 can be a rectangular opening groove structure formed on the installation platform 14. The guiding and connecting parts can be distributed on two opposite sides of the first installation groove 11. It can be understood that the two opposite sides of the first installation groove 11 are the two sides perpendicular to its extending direction. Taking the placement state when the test bracket 100 is in normal use as an example for illustration, the pressing block 30 is movably arranged along the guiding and connecting parts to fix or release the main beam 200. It can be understood that the guiding and connecting parts extend vertically. In the embodiments of the present application, the specific manner of the slidable fit between the pressing block 30 and the guiding and connecting parts is not limited. For example, the guiding and connecting parts can be a rod-shaped structure, and the pressing block 30 is matched with the guiding and connecting parts through a sliding groove; or the guiding and connecting parts have a groove structure, and the pressing block 30 has a convex structure matched with the groove structure, but it is not limited thereto. It can be understood that after the pressing block 30 is slid to the position where it presses the main beam 200, a locking component is needed to lock the relative position of the pressing block 30 and the guiding and connecting parts. The locking component can be a buckle structure or a pin hole and pin shaft structure, but it is not limited thereto. For example, when the guiding and connecting parts are a rod-shaped structure provided with threads, the locking component can be a nut structure; when the guiding and connecting parts have a groove structure, the locking component can be a fixed pin shaft, and correspondingly, the pressing block 30 is provided with a pin hole matched with the fixed pin shaft. The fixed pin shaft passes through the through hole on the groove structure and is matched with the pin hole on the pressing block 30 to fix the position of the pressing block 30 on the guiding and connecting parts.

[0045] As Figure 3 shown, in some embodiments, the guiding and connecting parts are threaded rods 12, and the pressing block 30 is movably arranged on the threaded rods 12. To enable the pressing block 30 to maintain the state of pressing the main beam 200, the test bracket 100 further includes a locking nut 13 matched with the threaded rods 12. The locking nut 13 provides a pressing force for the pressing block 30 through cooperation with the threaded rods 12 to fix the main beam 200 in the first installation groove 11 or the second installation groove 21. The pressing block 30 is provided with a sliding groove, and the pressing block 30 is sleeved on the threaded rods 12 through the sliding groove and slidably cooperates with the threaded rods 12. The locking nut 13 is arranged on the side of the pressing block 30 facing away from the first installation groove 11 or the second installation groove 21. After the pressing block 30 presses the main beam 200, the locking nut 13 is rotated to make the locking nut 13 closely abut against the pressing block 30, so as to realize the fixation of the main beam 200; when it is necessary to disassemble or replace the main beam 200, the locking nut 13 is rotated to the upper end of the threaded rods 12, and the pressing block 30 is moved upward, so that the disassembly or replacement of the main beam 200 can be realized. To facilitate the user to rotate the locking nut 13, the locking nut 13 can be a wing nut, but it is not limited thereto.

[0046] In some embodiments, at least two threaded rods 12 are provided, distributed on opposite sides of the pressing block 30. It can be understood that at least one threaded rod 12 is provided on each of the opposite sides of the pressing block 30. In the embodiments of the present application, taking two threaded rods 12 as an example for illustration, the base frame 10 further has a mounting seat body 15 provided on the mounting platform 14. The mounting seat body 15 is used to mount the threaded rod 12, and each threaded rod 12 corresponds to a mounting seat body 15. It can be understood that the two mounting seat bodies 15 are arranged at intervals, so that the two opposite mounting seat bodies 15 and the mounting platform 14 form a first mounting groove 11. The opposite surfaces of the two mounting seat bodies 15 can be vertical surfaces, so that the two mounting seat bodies 15 and the mounting platform 14 form a first mounting groove 11 in the shape of a rectangular groove. It should be noted that when the test bracket 100 is directly mounted on the rectangular main beam 200, the main beam 200 is directly embedded in the first mounting groove 11. Since the mounting platform 14 is generally made of metal, to ensure the stability of the main beam 200 mounted in the first mounting groove 11, a cushion plate 16 can be installed at the bottom of the first mounting groove 11. For example, the cushion plate 16 can be made of rubber material. When it is necessary to arrange a cushion block 20 in the first mounting groove 11, the cushion block 20 can be directly stacked on the cushion plate 16, but it is not limited thereto.

[0047] When the two mounting seat bodies 15 and the mounting platform 14 form a first mounting groove 11 in the shape of a rectangular groove, the cushion block 20 is detachably arranged in the first mounting groove 11, that is, the cushion block 20 is detachably arranged between the two mounting seat bodies 15, as Figure 4 and Figure 6 shown. In some embodiments, to facilitate the cushion block 20 to be quickly and accurately installed in place, the mounting seat body 15 further has a guiding groove 151. Correspondingly, the cushion block 20 has a guiding protrusion 23 that cooperates with the guiding groove 151. It can be understood that the guiding groove 151 is distributed on one side of the two opposite mounting seat bodies 15. The guiding groove 151 can be a through groove extending in the vertical direction. Thus, the cooperation between the guiding protrusion 23 of the cushion block 20 and the guiding groove 151 can position the installation position of the cushion block 20 along the extending direction of the first mounting groove 11. After the main beam 200 is placed in the second mounting groove 21, the locking nut 13 tightly abuts against the pressing block 30 to press and fix the main beam 200 in the second mounting groove 21. In this way, at the same time, the fixing of the main beam 200 by the pressing block 30 can be used to fix the cushion block 20 in the vertical direction. Of course, the cushion block 20 can also be detachably installed on the mounting platform 14 by other fasteners. Of course, in some other embodiments, the guiding groove 151 can also extend in the horizontal direction. When the guiding groove 151 extends in the horizontal direction, it can be a through groove with one end open.

[0048] As Figure 2 and Figure 4As shown, in some embodiments, the mounting base 15 further has a first opening groove 152. Since the two relatively arranged mounting bases 15 and the mounting platform 14 form a first mounting groove 11, it is equivalent to that the first opening grooves 152 on the two mounting bases 15 are distributed on the opposite sides of the first mounting groove 11, so that the openings of the first opening grooves 152 on the opposite sides of the first mounting groove 11 are arranged back to back. The threaded rod 12 is rotatably arranged in the first opening groove 152 around the central axis perpendicular to the threaded rod 12, that is, the two ends of the rotation axis of the threaded rod 12 are connected to the opposite side walls of the first opening groove 152. When the two threaded rods 12 rotate in the opposite direction to the horizontal, the threaded rod 12 is embedded in the first opening groove 152, and the free end of the threaded rod 12 extends out of the first opening groove 152 from the opening of the first opening groove 152. In the embodiments of the present application, by making the mounting base 15 have the first opening groove 152, the openings of the first opening grooves 152 of the two mounting bases 15 are arranged back to back, and the threaded rod 12 is rotatably arranged in the first opening groove 152 around the central axis perpendicular to the threaded rod 12. After the pressing block 30 is removed from the threaded rod 12, the two threaded rods 12 can be laid down, which is convenient for the disassembly and installation of the cushion block 20 and the backing plate 16. For example, as Figure 4 shown, the threaded rod 12 can be rotatably arranged in the first opening groove 152 through a rotating shaft 17. The central axis of the rotating shaft 17 is perpendicular to the central axis of the threaded rod 12. When the threaded rod 12 rotates around the rotating shaft 17 towards the opening direction of the first opening groove 152, the threaded rod 12 can be embedded in the first opening groove 152, so as to lay down the threaded rod 12.

[0049] It should be noted that since the threaded rod 12 is rotatably arranged in the first opening groove 152 around the central axis perpendicular to the threaded rod 12, there may be a gap between the threaded rod 12 and its rotating shaft, or there may be a gap between the rotating shaft of the threaded rod 12 and the mounting base 15. In some embodiments, as Figure 4 shown, the threaded rod 12 has a limiting surface 121 that cooperates with the first opening groove 152. The limiting surface 121 can be a cut surface formed on the circumferential surface of the threaded rod 12. When the limiting surface 121 cooperates with the first opening groove 152, the limiting surface 121 is parallel or fitted with the opposite side wall surfaces of the first opening groove 152. In the embodiments of the present application, by making the threaded rod 12 have the limiting surface 121 that cooperates with the first opening groove 152, on the one hand, the rotation of the threaded rod 12 around its central axis can be restricted, and on the other hand, when the threaded rod 12 is rotatably arranged in the first opening groove 152, it is convenient for the threaded rod 12 to be aligned with its rotating shaft.

[0050] As Figure 2 and Figure 5As shown, in some embodiments, correspondingly, second opening grooves 31 are provided on both opposite sides of the pressing block 30, and the openings of the second opening grooves 31 on the opposite sides are also arranged in opposite directions. The pressing block 30 is engaged with the threaded rod 12 through the second opening grooves 31, and when the threaded rod 12 rotates, the threaded rod 12 can be disengaged from the opening of the second opening groove 31. In this way, when disassembling the pressing block 30 from the threaded rod 12, after loosening the locking nut 13, rotate the threaded rod 12 so that the threaded rod 12 disengages from the opening of the second opening groove 31 of the pressing block 30, and the pressing block 30 can be removed from the threaded rod 12. Compared with moving the pressing block 30 to the end of the threaded rod 12, the disassembly operation of the pressing block 30 from the threaded rod 12 is effectively simplified.

[0051] As Figure 6 shown, in some embodiments, the second installation groove 21 has opposite first inclined side walls 211 and second inclined side walls 212. It can be understood that the inclination directions of the first inclined side wall 211 and the second inclined side wall 212 are opposite. For example, the second installation groove 21 can be a V-shaped groove or a trapezoidal groove, but is not limited thereto. In the embodiments of the present application, the second installation groove 21 is taken as an example of a trapezoidal groove for illustration. Among them, the first inclined side wall 211 and the second inclined side wall 212 can both have anti-slip structures 22 to increase the friction between the second installation groove 21 and the main beam 200 and effectively prevent the main beam 200 from moving. The specific structure of the anti-slip structure 22 is not limited in the embodiments of the present application. For example, the anti-slip structure 22 can be bumps, grooves or wavy anti-slip patterns formed on the first inclined side wall 211 and the second inclined side wall 212.

[0052] In addition, it should be noted that as Figures 7 to 10 shown, in some embodiments, to ensure that the pressing block 30 can be closely abutted against the main beam 200, a groove is further provided on the side of the pressing block 30 facing the first installation groove 11, and a fixing bolt 32 is provided at the groove. By rotating the fixing bolt 32, the end of the fixing bolt 32 is closely abutted against the main beam 200 to ensure the stability of the fixing of the main beam 200 by the test bracket 100.

[0053] In some embodiments, the test bracket 100 further includes a carrying handle 40. The carrying handle 40 is arranged on the base frame 10, so that the test bracket 100 can be carried and moved through the carrying handle 40. The specific number and specific structure of the carrying handle 40 are not limited in the embodiments of the present application. As Figure 2As shown, in some embodiments, for the convenience of carrying and moving the test bracket 100, the carrying handles 40 can be provided on opposite sides of the test bracket 100. For example, the two carrying handles 40 are distributed on opposite sides of the extension direction of the first mounting groove 11. Since the extension direction of the first mounting groove 11 is consistent with the central axis direction of the main beam 200, in this way, it is also convenient to adjust the position of the test bracket 100 through the carrying handles 40 after the main beam 200 is installed between the two test brackets 100. The carrying handle 40 can be a U-shaped frame structure, and both ends of the U-shaped frame are fixedly connected to the base frame 10.

[0054] In some other embodiments, the present application further provides a test system. The test system includes a main beam 200 and the test bracket 100 assembly in the above embodiments. The main beam 200 is used to install the photovoltaic module 300. Two test brackets 100 in the test bracket 100 assembly support the two ends of the main beam 200.

[0055] Taking the cross-sectional shape of the first mounting groove 11 in the test bracket 100 of the test bracket 100 assembly as a rectangle and the cross-sectional shape of the second mounting groove 21 as a trapezoid as an example for illustration, the main beam 200 in the test system can be a square tube main beam 200, a round tube main beam 200, a D-shaped main beam 200, or an octagonal main beam 200. When the main beam 200 is a square tube main beam 200, as Figure 7 shown, when installing the main beam 200, it is necessary to remove the cushion block 20 at the bottom of the first mounting groove 11 and directly place the main beam 200 in the first mounting groove 11. When the main beam is a round tube main beam 200, a D-shaped main beam 200, or an octagonal main beam 200, as Figures 8 to 10 shown, when installing the main beam 200, it is necessary to first set the cushion block 20 in the first mounting groove 11, and then place the main beam 200 in the second mounting groove 21 of the cushion block 20.

[0056] In the test system provided by the present application, all the technical solutions of all the above embodiments of the test bracket 100 are adopted. Therefore, it has at least all the beneficial effects brought by the technical solutions of the embodiments of the above test bracket 100, which will not be elaborated here one by one.

[0057] The above description is only the implementation mode of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
