Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module detection, and particularly to a mechanical load test device for photovoltaic modules and its automatic loading mechanism. Background Art

[0002] With the global energy shortage and climate warming, renewable energy such as solar power generation has gradually replaced traditional thermal power generation and become a hot research topic and development trend in the current energy field. As an important support for the power generation system, the reliability and safety tests of photovoltaic modules in the laboratory before mass production and factory shipment are particularly important.

[0003] Among many tests, the mechanical load test is a verification test to determine the ability of the module to withstand static loads such as wind, snow or ice. The mechanical load test has a long cycle and is widely used to detect the pressure resistance of photovoltaic modules. The dynamic pressure holding technology is used to simulate the load test to understand the compressive ability of the product under the load state.

[0004] However, existing photovoltaic modules are often relatively heavy. Coupled with the obstruction of the load-bearing beam of the experimental platform itself, it is usually very laborious to manually lift the entire photovoltaic module onto and off the experimental platform of the mechanical load testing machine in the laboratory, and the loading and unloading are very inconvenient. In addition, when manually lifting the photovoltaic module onto the experimental platform, it is inevitable that the placement direction of the module will be skewed due to force problems, and the operator needs to adjust the placement direction of the module again according to the position of the hydraulic cylinder of the testing machine, which is a waste of time. Therefore, it is necessary to design a mechanism that can conveniently transport the photovoltaic module onto the mechanical load testing machine without the need to adjust the direction of the module for the second time. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a mechanical load test device for photovoltaic modules and its automatic loading mechanism, which can efficiently and quickly transport the photovoltaic module onto the experimental platform of the mechanical load testing machine during the mechanical load test without the need to adjust the direction of the module for the second time.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] An automatic loading mechanism for a mechanical load test device of a photovoltaic module, comprising a pair of load racks spaced apart and facing each other in the horizontal direction, a first roller and a second roller provided on each of the load racks, a translation assembly for driving the load racks to approach and move away from each other, and a longitudinal movement assembly for driving the load racks to lift; each of the load racks includes a transverse load rack and a longitudinal load rack connected perpendicular to each other, and the free ends of the two transverse load racks face each other. A plurality of the first rollers are rotatably provided on the transverse load rack along the transverse axis of rotation, and at least one of the second rollers is rotatably provided on the longitudinal load rack along the longitudinal axis of rotation; the photovoltaic module placed on the transverse load rack is carried by the first rollers, and the second rollers on both sides are moved by the translation assembly to limit the ends, and the height is changed under the action of the longitudinal movement assembly.

[0008] As one of the implementation manners, the automatic loading mechanism of the mechanical load test device of the photovoltaic module further includes a balance rod. A guiding hole penetrating through its thickness direction is formed on each of the transverse load racks. The two ends of the balance rod are respectively movably inserted into the guiding holes on both sides, and the intersection of the transverse load rack and the longitudinal load rack is located between the guiding hole and the second roller.

[0009] As one of the implementation manners, in a direction perpendicular to the transverse axis of rotation and the longitudinal axis of rotation, a plurality of the first rollers and / or the second rollers are arranged.

[0010] As one of the implementation manners, the automatic loading mechanism of the mechanical load test device of the photovoltaic module further includes an induction probe. The induction probe is provided on the longitudinal load rack for detecting the distance between the two longitudinal load racks.

[0011] As one of the implementation manners, the longitudinal movement assembly includes a first swing member and a second swing member. The first end of the second swing member is rotatably connected to the first swing member, and the second end of the second swing member is rotatably connected to the longitudinal load rack; the free end of the first swing member is rotatably fixed to the side plate of the mechanical load test device of the photovoltaic module. During the swinging of the end of the first swing member connected to the second swing member, the height of the load rack is changed.

[0012] As another implementation manner, the longitudinal movement assembly includes a cylinder. One of the cylinder body or the piston rod of the cylinder is connected to the side plate of the mechanical load test device of the photovoltaic module, and the other is connected to the longitudinal load rack. During the operation of the cylinder, the height of the load rack is changed.

[0013] As one of the implementation manners, a part of the translation assembly is fixed on the balance bar, and the other part is fixed on the longitudinal carrier, so as to drive the longitudinal carrier to move along the balance bar during operation.

[0014] As one of the implementation manners, the translation assembly is a cylinder; alternatively, the translation assembly includes a ball screw and a ball nut that cooperate with each other, the ball screw is fixed on the balance bar, and the ball nut is fixed on the longitudinal carrier.

[0015] As one of the implementation manners, the automatic loading mechanism of the photovoltaic module mechanical load test device further includes a carrier plate connected to the longitudinal translation assembly. The longitudinal carrier is slidably arranged on the carrier plate along the length direction of the balance bar. A part of the translation assembly is fixed on the carrier plate, and the other part is fixed on the longitudinal carrier, so as to drive the longitudinal carrier to slide on the carrier plate during operation.

[0016] Another object of the present invention is to provide a photovoltaic module mechanical load test device, which includes an experimental platform, side plates arranged on both sides in the width direction of the experimental platform, and an automatic loading mechanism of any one of the above photovoltaic module mechanical load test devices. The two carriers are respectively arranged on the side plates on both sides through the longitudinal translation assemblies.

[0017] The present invention can use the rollers horizontally arranged on the transverse carrier to carry the photovoltaic module, and use the rollers vertically arranged on a pair of longitudinally adjustable carriers to limit the ends of the photovoltaic module. By adjusting the width and height between the longitudinal carriers, the loading and unloading operations of the photovoltaic module can be realized, and the direction of the photovoltaic module transported to the experimental platform has been preset in advance, so there is no need for secondary adjustment of the direction, which improves the loading efficiency and ensures the loading accuracy.

[0028] Example 1

[0029] Refer to Figure 1 , this embodiment provides an automatic loading mechanism for a photovoltaic module mechanical load test device. Among them, the photovoltaic module mechanical load test device includes an experimental platform and side plates provided on both sides in the width direction of the experimental platform. The automatic loading mechanism is installed on the side plates on both sides to transport the photovoltaic module to and lift it off the experimental platform.

[0030] The automatic loading mechanism mainly includes a pair of carriers 10 spaced apart and facing each other in the horizontal direction, a first roller 20 and a second roller 30 provided on each carrier 10, a translation assembly 40 for driving the carriers 10 to approach and separate from each other, and a longitudinal translation assembly 50 for driving the carriers 10 to lift and lower. Each of the carriers 10 includes a transverse carrier 11 and a longitudinal carrier 12 that are perpendicularly connected to each other, and the free ends of the two transverse carriers 11 face each other. A plurality of first rollers 20 are rotatably provided on the transverse carrier 11 along the transverse axis of rotation, and at least one second roller 30 is rotatably provided on the longitudinal carrier 12 along the longitudinal axis of rotation. The photovoltaic module placed on the transverse carrier 11 is carried by the first rollers 20, and the second rollers 30 on both sides are moved by the translation assembly 40 for end position limiting, and the height is changed under the action of the longitudinal translation assembly 50.

[0031] It can be understood that to ensure the best loading and limiting effects, the carrier 10, the first roller 20, the second roller 30, the translation assembly 40, and the longitudinal translation assembly 50 are preferably symmetrically arranged on both sides of the experimental platform, so that the first rollers 20 on both sides have the same height bearing surface, and the carriers 10 on both sides have synchronous movement actions, so as to simplify the operation and ensure the movement accuracy. The transverse carrier 11 and the longitudinal carrier 12 can be rod-shaped or plate-shaped, which is not limited here.

[0032] In this embodiment, to ensure that the transverse carrier 11 always remains horizontal and does not tilt during the lifting and translation of the carrier 10, the automatic loading mechanism may further include a balance rod 60. A guiding hole (not labeled in the figure) penetrating through its thickness direction is opened on each transverse carrier 11. The two ends of the balance rod 60 are respectively movably inserted into the guiding holes on both sides, and the intersection of the transverse carrier 11 and the longitudinal carrier 12 is located between the guiding hole and the second roller 30. That is, the balance rod 60 is located below the first roller 20 and spaced apart from the first roller 20 to avoid interference with the first roller 20 or the photovoltaic module. Limiters can be provided at both ends of the balance rod 60 to prevent axial loosening. For example, fasteners or circlips can be used for limiting.

[0033] It can be understood that in order to ensure the smooth cooperation between the balance bar 60 and the transverse carrier 11, the balance bar 60 and the transverse carrier 11 can be fitted through a linear bearing. That is, a linear bearing can be installed in the guiding hole, and the balance bar 60 can pass through the linear bearing for reciprocating movement.

[0034] To improve the automation level of the automatic feeding mechanism, the automatic feeding mechanism may further include an induction probe S, which is arranged on the longitudinal carrier 12 and can be used to detect the distance between the two longitudinal carriers 12. For example, the induction probe S can be an infrared induction probe or an ultrasonic probe, etc.

[0035] Before feeding, the tester can input the width of the photovoltaic module into the test software according to the nameplate information of the photovoltaic module. By detecting the distance between the longitudinal carriers 12 with the induction probe S, the distance between the longitudinal carriers 12 can be adjusted to a suitable width matching the width of the photovoltaic module by using the translation component 40 according to the width of the photovoltaic module.

[0036] Subsequently, during feeding, by controlling the longitudinal movement component 50 to work, the carrier 10 is lifted / lowered to a suitable feeding position, the photovoltaic module is placed on the first roller 20 and pushed horizontally to the designated position, so that the second rollers 30 on both sides are in contact with the ends on both sides of the photovoltaic module, thus realizing "clamping". In this way, the photovoltaic module is restricted in the center of the automatic feeding mechanism.

[0037] After the photovoltaic module is placed, by controlling the longitudinal movement component 50 to work, the carrier 10 moves vertically to another height, and the photovoltaic module is moved horizontally to the experimental platform. For example, the photovoltaic module can be manually pushed to roll on the first roller 20 to the experimental platform, or it can be translated by means of driving the first roller 20 with a motor.

[0038] It can be understood that in the direction perpendicular to the transverse axis of rotation and the longitudinal axis of rotation, a plurality of first rollers 20 and second rollers 30 can be arranged to better carry and limit the photovoltaic module, so as to achieve stable carrying and straight limiting.

[0039] As one of the implementation manners, the longitudinal movement component 50 of this embodiment includes a first swing member 51 and a second swing member 52. The first end ( Figure 1 the lower end in Figure 1 ) of the second swing member 52 is rotatably connected to the first swing member 51, and the second end ( the upper end in ) of the second swing member 52 is rotatably connected to the longitudinal carrier 12, and the free end of the first swing member 51 is used to be rotatably fixed on the side plate of the photovoltaic module mechanical load test device. During the process of the end of the first swing member 51 connected to the second swing member 52 swinging (i.e., the first swing member 51 swings around the side plate), the height of the carrier 10 changes, thereby realizing the adjustment of the height of the transverse carrier 11.

[0040] As Figure 1 shown, the figure shows the case where the first swing member 51 is perpendicular to the second swing member 52. When the first swing member 51 continues to swing upward around the side plate by a certain amplitude, the carrier frames 10 on both sides are in a stable and synchronous rising state under the limiting action of the balance rod 60; when the first swing member 51 continues to swing downward around the side plate by a certain amplitude, the carrier frames 10 on both sides are in a stable and synchronous descending state under the limiting action of the balance rod 60.

[0041] In this embodiment, a part of the translation assembly 40 is fixed on the balance rod 60, and the other part is fixed on the longitudinal carrier 12 to drive the longitudinal carrier 12 to move along the balance rod 60 during operation. Here, it is preferable that the translation assembly 40 is a cylinder, including a cylinder block and a piston rod. One of the cylinder block or the piston rod of the cylinder is connected to the balance rod 60, and the other is connected to the longitudinal carrier 12. During the operation of the cylinder, the piston rod expands and contracts to drive the longitudinal carrier 12 to approach and move away from each other, thereby changing the distance between the longitudinal carrier frames 12.

[0042] In other embodiments, the translation assembly 40 may include a ball screw and a ball nut that cooperate with each other. By fixing the ball screw on the balance rod 60 and the ball nut on the longitudinal carrier 12, and driving the ball screw to rotate clockwise or counterclockwise, the longitudinal carrier 12 can be driven to approach or move away from each other, thereby changing the distance between the carrier frames 12. It can be understood that the ball nut can also be fixed on the balance rod 60 and the ball screw can be fixed on the longitudinal carrier 12, and similar technical effects can still be achieved.

[0043] Among them, the translation assembly 40 can adjust and lock the distance between the longitudinal carrier frames 12. During the operation of the longitudinal translation assembly 50, the distance between the longitudinal carrier frames 12 remains constant.

[0044] Embodiment 2

[0045] As Figure 2 shown, different from Embodiment 1, the translation assembly 40 of this embodiment is not fixed on the balance rod 60, but a carrier plate 70 is separately provided at the bottom of the longitudinal carrier 12 for loading.

[0046] Specifically, the carrier plate 70 is rotatably connected above the longitudinal translation assembly 50 and carries the longitudinal carrier 12 and the translation assembly 40. The longitudinal carrier 12 is slidably arranged on the carrier plate 70 along the length direction of the balance rod 60 (i.e., Figure 2 the left - right direction in the figure), and a part of the translation assembly 40 is fixed on the carrier plate 70, and the other part is fixed on the longitudinal carrier 12 to drive the longitudinal carrier 12 to slide on the carrier plate 70 during operation.

[0047] Further, the automatic feeding mechanism further includes a slider 41 slidably disposed on the carrier plate 70. The bottom end of the longitudinal carrier 12 is fixed to the slider 41. A slide rail is provided on the carrier plate 70 and is opened along the length direction of the balance rod 60. The slider 41 is movably disposed on the slide rail and is limited in the vertical direction by the slide rail, that is, it cannot leave the slide rail in the vertical direction. The translation assembly 40 can adjust the distance between the longitudinal carriers 12 by driving the slider 41 to move along the slide rail.

[0048] For example, when the translation assembly 40 is a cylinder, it includes a cylinder block and a piston rod. The cylinder block of the cylinder can be fixed on the carrier plate 70, and its piston rod is connected to the slider 41. During the operation of the cylinder, the piston rod expands and contracts to drive the slider 41 to move along the slide rail, so that the longitudinal carriers 12 approach and move away from each other, thereby changing the distance between the longitudinal carriers 12. It can be understood that the cylinder block can also be fixed on the slider 41 and the piston rod can be fixed on the carrier plate 70, and similar technical effects can still be achieved.

[0049] Another example is that when the translation assembly 40 includes a ball screw and a ball nut that cooperate with each other, by fixing the ball screw on the carrier plate 70 and the ball nut on the slider 41, by driving the ball screw to rotate clockwise or counterclockwise, the slider 41 can be driven to move along the slide rail, so that the longitudinal carriers 12 approach or move away from each other, thereby changing the distance between the carriers 12. It can be understood that the ball nut can also be fixed on the carrier plate 70 and the ball screw can be fixed on the slider 41, and similar technical effects can still be achieved.

[0050] Embodiment 3

[0051] As Figure 3 shown, different from both Embodiment 1 and Embodiment 2, the longitudinal movement assembly 50 of this embodiment does not adopt the way of link swinging, but adopts cylinder drive.

[0052] Specifically, the cylinder block of the lifting cylinder 53 is connected to the side plate of the photovoltaic module mechanical load test device, and the piston rod is connected to the longitudinal carrier 12. During the operation of the lifting cylinder 53, the extended length of the piston rod changes, so that the height of the carrier 10 changes. It can also be that the piston rod of the lifting cylinder 53 is connected to the side plate of the photovoltaic module mechanical load test device, and the cylinder block is fixed on the longitudinal carrier 12. During the operation of the lifting cylinder 53, the extended length of the piston rod changes, and the height of the carrier 10 changes. Preferably, the piston rod of the lifting cylinder 53 is always perpendicular to the balance rod 60, that is, it is vertically arranged.

[0053] In summary, the present invention can use the rollers horizontally arranged on the transverse carrier to carry the photovoltaic module, and vertically arrange rollers on a pair of longitudinally adjustable carriers to limit the ends of the photovoltaic module. By adjusting the width and height between the longitudinal carriers through the adjusting member, the loading and unloading operations of the photovoltaic module can be realized. Moreover, the direction of the photovoltaic module transported to the experimental platform has been preset in advance, eliminating the need for secondary adjustment of the direction, improving the loading efficiency and ensuring the loading accuracy.

[0054] The above are only specific embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
