Detailed Description

Embodiments of the present application will be described in detail below with reference to examples, but those skilled in the art will appreciate that the following examples are only illustrative of the present application and should not be construed as limiting the scope of the present application.

The following description specifically describes the photovoltaic module testing system 1 and the photovoltaic module testing apparatus 10 provided in the embodiment of the present application:

currently, when performing an IV test on the photovoltaic module 100 in the industry, an operator needs to lift the photovoltaic module 100 horizontally placed to a fixed support which is about 1m higher than the ground, and then turn the photovoltaic module 100 horizontally placed on the fixed support 90 degrees and vertically fix the photovoltaic module.

The horizontal placement mode of the photovoltaic module 100 and the vertical placement mode of the photovoltaic module 100 are respectively shown in fig. 1 and fig. 2.

As shown in fig. 1, when horizontally placed, the thickness direction of the flat plate-like photovoltaic module 100 intersects with the horizontal direction, and even is perpendicular to the horizontal direction. That is, the horizontal placement is not limited to the thickness direction of the photovoltaic module 100 being necessarily perpendicular to the horizontal direction. By horizontally disposed, it is meant that the thickness direction of the photovoltaic module 100 is not parallel to the horizontal direction.

Accordingly, as shown in fig. 2, when the photovoltaic module 100 is vertically placed, the thickness direction of the plate-shaped photovoltaic module intersects with the gravity direction, or even is perpendicular to the gravity direction.

Likewise, the vertical placement does not limit the thickness direction of the photovoltaic module 100 to be perpendicular to the direction of gravity. By vertically disposed, it is meant that the thickness direction of the photovoltaic module 100 is not parallel to the direction of gravity.

However, in order to use solar energy more efficiently and reduce the power generation cost of the photovoltaic module 100, the size of the mainstream photovoltaic module 100 in the industry is getting larger. For example, the size and weight of the photovoltaic module 100 may reach 2278 × 1134mm (31.6 kg), 2468 × 1134mm (33.4 kg), or 2384 × 1303mm (38.7 kg).

At present, the weight of a single photovoltaic large-size component can reach nearly 80 jin, when the component is tested and fixed, if a manual carrying mode is adopted, when the photovoltaic component 100 with a large size is overturned and vertically installed on a support with the height of 1m in the vertical ground, the operation is difficult, the time consumption is long, and the safety risk exists.

Based on this, the inventor provides a photovoltaic module testing system 1 and a photovoltaic module testing device 10.

Referring to fig. 3, the photovoltaic module testing system 1 includes a photovoltaic module testing apparatus 10. Wherein, photovoltaic module testing arrangement 10 includes:

a carrier assembly 11; the bearing assembly 11 includes a supporting frame 111 and a fixing frame 112. The fixing frame 112 has a first plane 1121 for contacting the photovoltaic module 100, and fixing members 1124 are disposed at two sides of the fixing frame 112 for fixing the photovoltaic module 100 to the first plane 1121; the fixing frame 112 further has a first side 1122 and a second side 1123 opposite to each other, the first side 1122 is rotatably connected to the supporting frame 111, and the fixing frame 112 is selectively horizontally disposed on the supporting frame 111;

the upender assembly 12 comprises a jack 121; the output end of the lifting machine 121 is connected to the second side 1123 to push the horizontally disposed fixing frame 112 to rotate relative to the supporting frame 111, so that the photovoltaic module 100 fixed to the fixing frame 112 is vertically disposed.

By using the photovoltaic module testing device 10 provided by the example, the photovoltaic module 100 placed horizontally can be turned over, so that the photovoltaic module 100 is vertically placed, the turning operation of an operator on the photovoltaic module 100 is simplified, and the testing efficiency of the photovoltaic module 100 is improved.

The carrier assembly 11 and the flip assembly 12 in the photovoltaic module testing apparatus 10 provided in this example are further described in detail below with reference to the accompanying drawings.

The bearing component 11 is used for bearing the photovoltaic component 100, so that the photovoltaic component 100 can be stably vertically placed during testing.

Referring to fig. 4, the supporting assembly 11 includes a supporting frame 111 and a fixing frame 112. The fixing frame 112 is selectively horizontally placed on the supporting frame 111 to support the fixing frame 112 at a position having a certain height from the bottom surface.

The fixing frame 112 is used for fixing the photovoltaic module 100, so that the photovoltaic module 100 horizontally placed on the fixing frame 112 can be vertically placed along with the rotation of the fixing frame 112.

In the example, the fixture 112 has a first plane 1121 for contacting the photovoltaic module, and a first side 1122 and a second side 1123 disposed opposite to each other. Before the photovoltaic module 100 is turned over, the photovoltaic module 100 needs to be horizontally placed on the fixing frame 112 and then vertically placed along with the turning over of the fixing frame 112. Because the photovoltaic module 100 is a flat plate structure, the first plane 1121 is disposed in the fixing frame 112, so that when the photovoltaic module 100 needs to be horizontally placed on the fixing frame 112, the photovoltaic module 100 can be stably contacted with the first plane 1121 in the fixing frame 112, the photovoltaic module 100 is prevented from being warped due to the unevenness of the fixing frame 112, and the safety of the photovoltaic module 100 can be further improved.

After the photovoltaic module 100 is horizontally placed on the first plane 1121, the fixing frame 112 rotates around the first side 1122 under the action of the lifter 121.

In order to prevent the photovoltaic module 100 from being separated from the first plane 1121 during the rotation of the fixing frame 112 around the first side 1122 thereof, in a possible embodiment, the fixing members 1124 are disposed on the first side 1122 and the second side 1123 to fix the photovoltaic module 100 to the first plane 1121. Alternatively, the fasteners 1124 are disposed on third and fourth sides adjacent to the first and second sides 1122, 1123.

The specific arrangement form of the support frame 111 is not limited in the present application, and related personnel can make corresponding adjustment as needed while ensuring that the fixing frame 112 can be placed on the support frame 111 in a selectable horizontal manner and is rotatably connected with the first side 1122 of the fixing frame 112.

In some possible embodiments, with continued reference to fig. 4 and 5, the supporting frame 111 includes a first bracket 1111 and a second bracket 1112 arranged in a crisscross manner. The first bracket 1111 horizontally disposed is used for supporting the fixing frame 112 horizontally disposed, and the second bracket 1112 vertically disposed is used for supporting the fixing frame 112 vertically disposed.

In order to horizontally place the fixing frame 112 on the first bracket 1111 and vertically place the fixing frame 112 on the second bracket 1112 after the fixing frame 112 is rotated, in the example, the first side 1122 of the fixing frame 112 is rotatably connected to the top end of the second bracket 1112. That is, the second side 1123 of the fixing frame 112 can be selectively placed at the end of the first bracket 1111 far from the second bracket 1112, and the first side 1122 of the fixing frame 112 is rotatably connected to the top end of the second bracket 1112 near the first bracket 1111.

Further, the application does not limit the specific arrangement form of the first bracket 1111 and the second bracket 1112, and relevant personnel can make corresponding adjustments as needed.

In some possible embodiments, the first bracket 1111 includes a horizontally disposed first support plate 11111, and four pillars 11112 vertically protruding above the upper surface of the first support plate 11111.

The first support 1111 is configured as a horizontally disposed first support plate 11111 and four support columns 11112 protruding from the upper surface of the first support plate 11111, so that when the fixing frame 112 is horizontally disposed on the four support columns 11112, the lifter 121 or other members disposed at the first support plate 11111 below the four support columns 11112 does not interfere with the horizontal disposition of the fixing frame 112.

Further, in order to support the horizontally disposed fixing frame 112 at a position having a certain height from the ground, a support leg having a certain height may be provided on the bottom surface of the first support plate 11111, and the first support plate 11111 may be lifted by a certain height.

In some possible embodiments, referring to fig. 5, the second support 1112 includes at least two columns 11121 and a bearing rod 11122 coupled to the at least two columns 11121. A connecting hole is formed in the first side 1122, and the bearing rod 11122 is sleeved with the first side 1122 through the connecting hole.

Further, in order to improve the stability of the second support 1112, the bottom ends of the two upright posts 11121 may be fixed to the ground; alternatively, the second bracket 1112 is fixed to one end of the first bracket 1111.

The fixing frame 112 is used for fixing the photovoltaic module 100 and driving the photovoltaic module 100 to be vertically placed from a horizontal placement. The application is not limited to the specific arrangement form of the fixing frame 112, and the relevant personnel can make corresponding adjustments as required.

In some possible embodiments, the fixing frame 112 is a flat plate structure, and the upper surface of the flat plate structure is provided with a groove. The bottom of the groove is a first plane 1121, and the edge of the first plane 1121 has a first side 1122 and a second side 1123 opposite to each other. The depth of the recess is not less than the thickness of the photovoltaic module 100 to place the photovoltaic module 100 in the recess.

Further, in order to prevent the photovoltaic module 100 from being separated from the first plane 1121 during the rotation process of the fixing frame 112, fixing members 1124 are rotatably connected to the top ends of the first side 1122 and the second side 1123 away from the first plane 1121. When the photovoltaic module 100 needs to be fixed, the fixing member 1124 is rotated to make the first side 1122 or the second side 1123 opposite to the first plane 1121. The extended fixing member 1124 is opposite to the first plane 1121, and blocks the photovoltaic module 100 placed on the first plane 1121 from being separated from the first plane 1121.

Further, the application does not limit how the fixing member 1124 is rotatably connected to the first side 1122 and the second side 1123, and in some possible embodiments, a rotating shaft is disposed at a top end of the first side 1122, and the fixing member 1124 is sleeved on the rotating shaft.

Further, in order to reduce the weight of the fixing frame 112, the first plane 1121 may be configured to be hollowed.

The turnover assembly 12 is used for driving the fixing frame 112 to rotate, so that the fixing frame 112 which is horizontally placed is vertically placed.

In the example, the flipping module 12 includes a lifter 121, and an output end of the lifter 121 is connected to the second side 1123 of the fixing frame 112 to rotate the fixing frame 112 around the first side 1122.

The application does not limit how the lifting machine 121 drives the fixing frame 112 to rotate, and in some possible embodiments, an air cylinder may be used to set a fixed end of the air cylinder at an end of the first bracket 1111 away from the second bracket 1112, so as to push the second side 1123 to rotate around the first side 1122.

Further, in order to prevent the air cylinder from interfering with the horizontal placement of the fixing frame 112 on the first bracket 1111, a fixed end of the air cylinder may be disposed on the first support plate 11111 to separate a certain distance from the bottom of the horizontally placed fixing frame 112.

To further facilitate adjusting the rotating angle of the lifting machine 121 for lifting the fixing frame 112 and improving the stability of the fixing frame 112 during rotation, the fixed end of the lifting machine 121 may be slidably connected to the first supporting plate 11111 through the adjusting member 122, and the rotating angle of the fixing frame 112 may be adjusted by adjusting the distance between the fixed end of the lifting machine 121 and the first side 1122.

Since the first side 1122 is fixed at the second bracket 1112, when the fixed end of the lifting machine 121 is closer to the first side 1122, so that the fixed frame 112 rotates by the same angle, the smaller the lifting length of the lifting machine 121 is paid out, the smaller the possibility of shaking during the lifting process is, and the stability of the fixed frame 112 during the rotation process can be further improved.

The closer the fixed end of the lifter 121 is to the first side 1122, the greater the angle of rotation of the mount 112 about the first side 1122 at a given lifting length of the lifter 121.

The present application does not limit the specific arrangement of the adjusting member 122, and in one possible embodiment, the adjusting member 122 includes a conveying belt 1221 and a driver 1222 for driving the conveying belt 1221 to move. The driver 1222 may be a motor.

Further, the conveyor belt 1221 and the driver 1222 are provided to the first support plate 11111.

The fixed end of the lifter 121 is disposed on the conveyor belt 1221, and the distance between the fixed end of the lifter 121 and the first side 1122 may be adjusted along with the movement of the conveyor belt 1221.

Alternatively, a plurality of mounting grooves may be formed in the first support plate 11111 at intervals along a predetermined direction, and the fixed end of the lifting machine 121 may be selectively engaged in different mounting grooves to adjust the distance between the fixed end of the lifting machine 121 and the first side 1122.

Alternatively, in some possible embodiments, the jack 121 may include a support bar, and a second drive member. The two ends of the support rod are slidably connected to the bottom surface of the fixing frame 112 and the first support plate 11111, respectively. When the fixing frame 112 needs to be vertically turned over, the second driving element can be used for driving the supporting rod to slide along the direction close to or far away from the first side 1122, and then the fixing frame 112 placed horizontally can be turned over to be vertically arranged.

Furthermore, corresponding sliding grooves can be formed in the bottom surface of the fixing frame 112 and the first supporting plate 11111, so that the supporting rods can slide along the sliding grooves, and the stability of the fixing frame 112 in the overturning process can be improved.

The photovoltaic module testing system 1 provided by the present example further includes a light source 20. The light source 20 has a vertical light emitting surface to irradiate a light receiving surface of the photovoltaic module 100 placed vertically, and perform an IV test on the photovoltaic module 100.

Further, the photovoltaic module testing system 1 may further include a processor for processing, displaying or outputting test data such as current and voltage during the testing process.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
