Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a hail test stand with adjustable component testing angle. Background Technology

[0002] With the continuous growth of photovoltaic (PV) installations, the requirements for PV module product inspection and testing are gradually increasing, and industry standards are being improved and perfected. As industry standards are updated, the testing requirements for PV modules also need to be updated accordingly. For hail testing of PV modules, most companies currently need to test the results of hail tests under different installation angles. However, current adjustable-angle hail testing machines all rotate the PV module around another fulcrum by adjusting the height of one fulcrum, as shown in the testing device disclosed in patent number CN209858166U. This adjustment method results in a complex rotating structure and limited rotation angle. Furthermore, locking the rotation angle of the PV module can only be achieved by locking the drive mechanism, as shown in the PV bracket disclosed in patent number CN108809225A. During testing, this can easily become loose, leading to reduced testing accuracy.

[0003] Therefore, designing a hail test bracket with a simple structure and better locking effect is a technical problem that needs to be solved. Utility Model Content

[0004] To address the technical problems of existing hail testing machines, such as complex structure, limited rotation angle, and insufficient testing accuracy, this invention provides a hail testing bracket with adjustable component testing angles to solve these problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hail test bracket with adjustable component testing angle, including a support beam, a locking component, a driving component, two columns and at least two support frames. The support beam has two circular shaft segments located above the two columns respectively. The support frames are installed on the support beam for placing photovoltaic modules, and the support frames have pressure blocks for fixing the photovoltaic modules. The locking component connects one of the columns and the circular shaft segments, and the locking component is adapted to suppress the rotation of the support beam. The driving component connects the other column and the circular shaft segments, and the driving component drives the support beam to rotate by driving the circular shaft segments to rotate.

[0006] In an optional embodiment of this utility model, the drive assembly includes a drive motor and a meshing active bevel gear and a driven bevel gear. The active bevel gear is connected to the output shaft of the drive motor, and the driven bevel gear is connected to a circular shaft section. The drive motor is installed inside the column.

[0007] In an optional embodiment of this utility model, a plurality of pin holes are provided on the circular shaft section connecting the locking component, and the locking component is a pin inserted into the circular shaft section.

[0008] In an optional embodiment of this utility model, the locking assembly includes a fixed beam, a locking rod, a locking clamp, and an open ring. The open ring is located on the inner circumference of the locking clamp and is sleeved on the outside of the round shaft section. The locking rod passes through both ends of the locking clamp. The fixed beam is fixed inside the column. One end of the locking rod is provided with a head, and the other end is threaded with the fixed beam. The locking clamp is tightened under the clamping action of the head and the fixed beam.

[0009] In an optional embodiment of this utility model, the openings of the locking clamp and the opening ring face opposite directions.

[0010] In an optional embodiment of this utility model, an operating rod is inserted into the end of the locking rod, and the fixing beam is located between the operating rod and the locking clamp.

[0011] In an optional embodiment of this utility model, the top of the column is open and hollow inside, and a protective cover is installed on the top of the column, which covers the outside of the locking component or the driving component.

[0012] In an optional embodiment of this utility model, the two columns are fixed to the base plate.

[0013] In an optional embodiment of this utility model, the support frame has a sliding groove that slides with the pressure block, and the pressure block and the support frame are locked together by bolts.

[0014] In an optional embodiment of this utility model, the support beam includes a prism segment connected to the circular shaft segment, the outer surface of the support frame is prism-shaped, and the support frame is fixed to the prism segment of the support beam by a U-shaped clamp.

[0015] The beneficial effects of this utility model are:

[0016] (1) The drive component in this utility model acts directly on the circular shaft section to drive the support beam to rotate. It does not require the conversion of the linear motion mechanism, and the drive structure is more simplified. At the same time, the support beam is directly locked by the locking component to fix the angle of the support beam, so as to avoid the angle of the support beam from deflecting during the test and ensure the test accuracy.

[0017] (2) This utility model controls the angle change of the support beam by rotating the circular shaft segment, without the need to set up extra support points, and the rotation angle is not limited.

[0018] (3) The present invention uses a clamping method to lock the support beam, which can achieve locking at any angle and direction, and ensure angle accuracy. Attached Figure Description

Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] Example 1

[0030] like Figures 1-3As shown, a hail test stand with adjustable component testing angle includes a support beam 5, a locking assembly, a drive assembly, two columns, and at least two support frames 6. The support beam 5 has two circular shaft segments located above the two columns respectively. The support frames 6 are mounted on the support beam 5 for placing photovoltaic modules 12, and the support frames 6 have pressure blocks 7 for fixing the photovoltaic modules 12. The locking assembly connects one of the columns and the circular shaft segments, and the locking assembly is adapted to suppress the rotation of the support beam 5. The drive assembly connects the other column and the circular shaft segments, and the drive assembly drives the support beam 5 to rotate by driving the circular shaft segments to rotate.

[0031] Multiple support frames 6 are arranged along the same plane, allowing photovoltaic modules 12 to be placed horizontally. The edges of the photovoltaic modules 12 are then held in place by pressure blocks 7. The circular shaft segment refers to a shaft with a circular cross-section, facilitating rotational connection and allowing the support beam 5 to engage with the locking and driving components at any angle. For the installation of the pressure block 7 and the support frame 6, a sliding groove 601 can be provided on the support frame 6 for sliding engagement with the pressure block 7. The pressure block 7 and the support frame 6 are locked together with bolts. When the position of the pressure block 7 needs to be adjusted, the bolts are loosened, and after the pressure block 7 presses onto the photovoltaic module 12, the bolts are tightened to lock the pressure block 7 and the support frame 6 together.

[0032] Two columns support the support beam 5 and also house the locking and driving components. For ease of distinction, in the following description, the two columns are named locking column 2 and angle adjusting column 3, respectively. The circular shaft segment above locking column 2 is named chain shaft 501, and the circular shaft segment above angle adjusting column 3 is named rotating shaft 502. The locking component connects locking column 2 and chain shaft 501, and the driving component connects angle adjusting column 3 and rotating shaft 502. The driving component can directly drive rotating shaft 502 to rotate, while the locking component loosens or locks chain shaft 501.

[0033] When the photovoltaic module 12 rotates to the specified angle, the drive component shuts off, and the locking component locks the chain shaft 501. Thus, the angle of the photovoltaic module 12 can be fixed through the self-locking of the drive component and the direct action of the locking component on the chain shaft 501, effectively preventing angle deflection during the hail test.

[0034] Except for the circular shaft section, all other shaft sections of support beam 5 are square shafts, such as... Figure 1 and Figure 3 As shown, the circular shaft section is connected to prismatic sections at both ends. The outer surface of the support frame 6 is prismatic. The support frame 6 is fixed to the prismatic section of the support beam 5 by U-shaped clamps 4. The square shaft design allows the support frame 6 to make planar contact with the support beam 5, facilitating fixation and preventing slippage. The U-shaped clamp 4 refers to the U-shaped rod 401 that passes over the support frame 6 and connects to the panel located below the support beam 5.

[0035] The drive assembly acts directly on the rotating shaft 502. The drive assembly may, but is not limited to, the following structure: including a drive motor 8 and meshing driving bevel gear 9 and driven bevel gear 10. The driving bevel gear 9 is connected to the output shaft of the drive motor 8, and the driven bevel gear 10 is connected to the round shaft section. The drive motor 8 is mounted inside the column. Figure 2 As shown, the angle adjustment column 3 is hollow inside, and the drive motor 8 is fixed on the mounting base 302 inside the angle adjustment column 3. The top of the angle adjustment column 3 is provided with an opening for the driven bevel gear 10 to extend into and mesh with the driving bevel gear 9. The driving bevel gear 9 is arranged vertically on the central axis, and the driven bevel gear 10 is coaxial with the rotating shaft 502. The overall structure is simple and occupies a small area.

[0036] The fit between the locking assembly and the round shaft section:

[0037] In one optional embodiment of this utility model, the circular shaft segment connecting the locking assembly is provided with a plurality of pin holes, and the locking assembly is a pin inserted into the circular shaft segment. The denser the arrangement of the pin holes, the higher the angle fixing accuracy; however, since the pin holes cannot be arranged continuously in the circumferential direction, it is impossible to achieve accurate locking at any angle.

[0038] To ensure angle locking accuracy, this embodiment adopts the following locking component structure:

[0039] The locking assembly includes a fixed beam 202, a locking rod 1102, a locking clamp 11, and an open ring 1101. The open ring 1101 is located on the inner circumference of the locking clamp 11 and is fitted around the cylindrical section. The locking rod 1102 passes through both ends of the locking clamp 11. The fixed beam 202 is fixed inside the column. One end of the locking rod 1102 has an end cap 1103, and the other end is threaded into the fixed beam 202. The locking clamp 11 is tightened under the clamping action of the end cap 1103 and the fixed beam 202. Figure 2 , Figures 4-6 As shown, the locking column 2 is hollow inside, and the fixing beam 202 is installed inside the locking column 2. The fixing beam 202 has a mounting hole 2021. The locking rod 1102 passes through the locking clamp 11 and the mounting hole 2021. Since the fixing beam 202 is a fixed structure, rotating the locking rod 1102 can move the end 1103 closer to or further away from the fixing beam 202, thereby tightening or loosening the locking clamp 11. The open ring 1101 inside the locking clamp 11 also tightens or loosens along with the locking clamp 11. The opening directions of the open ring 1101 and the locking clamp 11 are different, and the clamping effect is ensured by an inner and outer sleeve connection. In a preferred embodiment, the openings of the locking clamp 11 and the open ring 1101 face opposite directions.

[0040] Example 2

[0041] In the locking assembly described in the above embodiment, the locking rod 1102 is a round rod, which is relatively difficult to rotate. Therefore, in this embodiment, an operating rod 1104 is inserted into the end of the locking rod 1102, and the fixing beam 202 is located between the operating rod 1104 and the locking clamp 11. Figure 5 As shown, the operating lever 1104 is located at the right end of the locking lever 1102 and is arranged perpendicular to the locking lever 1102. Torque can be applied to the operating lever 1104 to control the rotation of the locking lever 1102, making operation easier.

[0042] Example 3

[0043] Based on the above embodiments, in order to protect the locking assembly and the drive assembly, this embodiment installs a protective cover on the top of each column, the protective cover covering the outside of the locking assembly or the drive assembly. Figure 2 and Figure 3 As shown, the protective cover installed on the locking column 2 is the locking mounting cover 201, and the protective cover installed on the angle adjusting column 3 is the angle mounting cover 301.

[0044] Example 4

[0045] Based on the above embodiment, the two columns are fixed on the base plate 1, thereby increasing the contact area between the device and the ground and ensuring the stability of the device.

[0046] Instructions for use: When a hail test is required on the photovoltaic module 12, adjust the hail test bracket to a horizontal position (e.g., Figure 7 As shown, the photovoltaic module 12 is placed on the support frame 6 and fixed by the pressure block 7. When it is necessary to adjust the tilt angle of the photovoltaic module 12, the drive motor 8 is started. The drive motor 8 drives the support beam 5 to rotate through the bevel gear. The rotation of the support beam 5 in turn drives the photovoltaic module 12 to rotate. The rotation angle is set by the program. After the required test angle is reached, the drive motor 8 is stopped and the locking rod 1102 is rotated. The locking rod 1102 locks the locking chain shaft 501 through the locking clamp 11 and the open ring 1101 to ensure that the support beam 5 is in a locked state. Then the hail tester 13 sprays hail to conduct hail tests on different positions of the photovoltaic module 12.

[0047] After the hail test is completed, rotate the locking rod 1102 in the opposite direction to put the locking component in a non-locked state, start the drive motor 8 to return the photovoltaic module 12 to a horizontal state, slide the pressure block 7, and remove the photovoltaic module 12. If it is necessary to continue testing other components, repeat the above operation; if it is not necessary to conduct tests, stop.

[0048] In this specification, the illustrative expressions of the terms do not necessarily refer to the same embodiments. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.

[0049] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
