[0035] In order to better understand the purposes, structures and functions of the present application, the following will be combined with the accompanying drawings to further describe the present application. Figures 1 to 10 The visual comparison device for color difference of the photovoltaic module is further described in detail.

[0036] As shown in Figure 1 the embodiment of the present application, the visual comparison device for color difference of the photovoltaic module comprises a moving trolley, a track assembly and a rotating assembly.

[0037] As shown in Figure 1 and Figure 2As shown, the mobile trolley includes a trolley framework 41, which is the main body of the mobile trolley and serves to support other components. Inside the trolley framework 41, a plurality of trolley counterweights 46 are arranged. The trolley counterweights 46 serve to lower the center of the mobile trolley and thereby stabilize the mobile trolley, avoiding the risk of the entire device toppling due to the weight of the track assembly and the rotating assembly during the comparison process. A plurality of trolley universal wheels 44 and a plurality of trolley positioning wheels 45 are arranged at the bottom of the trolley framework. During the comparison process, the mobile trolley can be pushed and / or pulled according to the actual situation. The mobile trolley is pushed and / or pulled to the appropriate position by the rolling of the trolley universal wheels 44 and the trolley positioning wheels 45. After the comparison work is completed, the mobile trolley can also be pushed and / or pulled to the storage position, avoiding the obstruction of other production activities when the mobile trolley is not in use. When the mobile trolley is pushed and / or pulled to the destination position, the trolley positioning wheels 45 can be fixed by the positioning device on the trolley positioning wheels 45 so that they do not rotate, thereby preventing the mobile trolley from moving.

[0038] In the present utility model, the trolley framework 41 is further fixedly provided with a trolley arc-shaped track 42. The convex side of the trolley arc-shaped track 42 is connected with the trolley framework 41, and the concave side of the trolley arc-shaped track 42 is further provided with a trolley arc-shaped lining plate 43. The track assembly can slide on the trolley arc-shaped lining plate 43, so that the photovoltaic assembly at different angles can be visually observed, and the photovoltaic assembly at different angles can be visually compared.

[0039] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 6 , in the track assembly, a top track support assembly 21 is arranged. The side of the top track support assembly 21 facing the mobile trolley is further provided with two upper rolling tracks 22. The two upper rolling tracks 22 are designed in parallel, and the length direction of the upper rolling tracks 22 is the length direction of the mobile trolley. A plurality of upper support front plates 211 and a plurality of upper support rear plates 212 are arranged on the edges of the top track support assembly 21. The two upper rolling tracks 22 are located between the upper support front plates 211 and the upper support rear plates 212. The upper support front plates 211 and the upper support rear plates 212 are connected by screws and have a pressing block 26. By rotating the screw, the distance between the pressing block 26 and the upper support front plate 211 or the upper support rear plate 212 can be adjusted.

[0040] It can be understood that the upper rolling track 22 is also provided with a track support part which can roll in the upper rolling track 22, the track support part comprises a rolling beam 233, a plurality of rolling shafts 232 are fixedly arranged on the rolling beam 233, and rolling wheels 231 are arranged on the rolling shafts 232 and rolling contact with the upper rolling track 22. A plurality of hooking screw holes are arranged on the rolling beam 233, a rolling stud bolt 235 is arranged on the hooking screw hole, and a rolling connecting block 234 is threadedly fixed on the rolling stud bolt 235 and located on one side of the rolling beam 233 facing the lower rolling track 25. The rolling stud bolt 235 is also connected with a connector 27 which is connected with the rolling stud bolt 235 through threads, and the connector 27 is in contact with the rolling connecting block 234 after being installed on the rolling stud bolt 235. The rolling connecting block 234 serves to keep a gap between the connector 27 and the upper rolling track 22, so that the connector 27 does not contact the upper rolling track 22 and affect the rolling of the track support part. Since the rolling connecting block 234 is in contact with the rolling beam 233 and the connector 27, the stability of the connector 27 is improved, and the connector 27 is prevented from shaking due to the connection between the connector 27 and the rolling beam 233 through the rolling stud bolt 235 only. Track limiting blocks 28 are arranged at both ends of the upper rolling track 22 to prevent the track support part from rolling out of the upper rolling track 22 during use.

[0041] The track assembly is also provided with a spherical sliding body assembly 24 which is used to slide on the trolley arc-shaped lining plate 43. The spherical sliding body assembly 24 is similar to the top track support assembly 21 and is also fixedly provided with a lower rolling track 25, a lower support front plate 241 and a lower support rear plate 242, and the lower rolling track 25 is located between the lower support front plate 241 and the lower support rear plate 242. A track support part is arranged in the lower rolling track 25 and is in rolling connection with the lower rolling track 25 during use. The lower support front plate 241 and the lower support rear plate 242 are also provided with pressing blocks 26 which have the same effect as the pressing blocks 26 arranged on the upper support front plate 211 or the upper support rear plate 212. The connector 27 is also arranged on the track support part in the lower rolling track 25 and has the same effect. Track limiting blocks 28 are also arranged at both ends of the lower rolling track 25, and the track limiting blocks 28 are also used to prevent the track support part from rolling out of the lower rolling track 25 during use.

[0042] In use, the photovoltaic sheet 1 of the standard plate and the two ends of the photovoltaic sheet 1 to be compared are inserted into the connector 27, and the track support part connected by the connector 27 is placed into the upper rolling track 22 and the lower rolling track 25. Next, the distance between the pressing block 26 and the photovoltaic sheet 1 is adjusted, so that a certain gap is reserved between the photovoltaic sheet 1 and the pressing block 26, for example, the distance between the photovoltaic sheet 1 and the pressing block 26 is 0.5 mm, so that the pressing block 26 does not rub against the photovoltaic sheet 1 when the position of the photovoltaic sheet 1 is adjusted.

[0043] As shown in Figure 3 , Figure 4 , Figure 9 and Figure 10 , in order to replace the photovoltaic sheet 1 to be compared and compare multiple photovoltaic sheets 1 to be compared, the upper rolling track 22 and the lower rolling track 25 are designed with two parallel tracks. The combination of the photovoltaic sheet 1 of the standard plate and the track support part is first placed into one of the tracks of the upper rolling track 22 and the lower rolling track 25, and the combination of the photovoltaic sheet 1 to be compared and the assembly 23 is placed into the other track of the upper rolling track 22 and the lower rolling track 25. Since the track support part can roll in the upper rolling track 22 and the lower rolling track 25, the relative positions of the photovoltaic sheets 1 can be adjusted according to the needs of the comparison test. For example, the photovoltaic sheet 1 of the standard plate can be placed between the two photovoltaic sheets 1 to be compared, or the photovoltaic sheet 1 of the standard plate can be placed on the leftmost or rightmost side. When it is necessary to replace the photovoltaic sheet 1 to be compared, the track limiting block 28 is first disassembled, and then the combination of the photovoltaic sheet 1 and the track support part is removed. After replacing the photovoltaic sheet 1, the combination of the photovoltaic sheet 1 and the track support part is placed into the upper rolling track 22 and the lower rolling track 25. After the track limiting block 28 is installed, the comparison test can continue.

[0044] As shown in Figure 7 and Figure 8 , in the utility model, the track assembly and the rotating assembly are fixedly connected, the rotating assembly comprises an upper track support part 31, a middle track support part 32 and a lower track support part 33, wherein the upper track support part 31 is fixedly connected with the upper support rear plate 212, and the lower track support part 33 is fixedly connected with the lower support rear plate 242; and one end of the middle track support part 32 is connected with the upper track support part 31, and the other end is connected with the lower track support part 33. A rotating vertical plate 34 is further fixedly connected to the side opposite to the track assembly of the middle track support part 32. The rotating vertical plate 34 can increase the contact area between the rotating assembly and the track assembly, and improve the stability of the fixation.

[0045] The upper part of the rotating vertical plate 34 is fixedly connected with a second shaft seat 362, and a third shaft seat 363 is fixedly arranged on the rotating vertical plate 34 and located below the second shaft seat 362. The second shaft seat 362 is rotatably connected with the second support rod 352 through a second rotating shaft pin 372, and the second support rod 352 is rotatably connected with the first shaft seat 361 through a first rotating shaft pin 371; a rotating nut 353 is fixedly connected on the first shaft seat 361, the rotating nut 353 is rotatably connected with a rotating screw rod, and the rotating screw rod includes a screw threaded part 354 and a screw handle part 355. The screw threaded part 354 is fixedly connected with a rotating bearing 356 after penetrating through the rotating nut 353, and the rotating bearing 356 is fixedly connected with the first support rod 351. The end of the first support rod close to the rotating bearing 356 is rotatably connected with the third shaft seat 363 through a third rotating shaft pin 373. The other end of the first support rod is fixedly connected with the vertical support rod 381 of the rotating support assembly.

[0046] It can be understood that the rotating support assembly further includes a plug-in support part 382, and the vertical support rod 381 is inserted into and fixedly connected with the plug-in support part 382. The opposite side of the plug-in support part 382 connected with the vertical support rod 381 is fixedly connected with the trolley framework 41. The plug-in support part 382 is arranged to increase the fixed connection area between the vertical support rod 381 and the trolley framework 41 and improve the stability of the connection.

[0047] In the description of the human eye observing an object in the standard of Architectural Physics and Architectural Equipment, it is mentioned that the 30° around the line of sight looks clearer. The field of view of the human eye perpendicular to the surface of the observed object is defined as the standard field of view 0°, and the 30° upward rotation of the surface of the observed object is the color discrimination limit. Therefore, when observing the appearance of the photovoltaic sheet 1 at a distance close to 2 times the height of the photovoltaic sheet 1, the color difference can be clearly observed.

[0048] As Figure 1 and Figure 8As shown, after the photovoltaic sheet 1 is installed, the photovoltaic sheet 1 is perpendicular to the horizontal ground as an initial state, in order to better observe the color of each photovoltaic sheet 1, the rotating screw needs to be rotated to adjust the observation angle of the photovoltaic sheet 1 and the human eye. The operator rotates the rotating screw by holding the screw handle part 355, and with the rotation of the rotating screw, the rotating nut 353 moves towards the vertical support rod 381, and simultaneously drives the movement of the second support rod 352. During the rotation process, the second support rod 352 moves, and the first support rod 351 is in a static state, so that the middle rail support part 32 rotates around the third shaft seat 363, and at the same time, the rail assembly also rotates around the third shaft seat 363, and the spherical sliding body assembly 24 slides on the trolley arc-shaped lining plate 43. The arc surface formed by the trolley arc-shaped lining plate 43 and the trolley arc-shaped rail 42 can support the rotation of the rail assembly and define the position.

[0049] In the utility model, in order to more fully observe the photovoltaic sheet 1, the photovoltaic sheet 1 can be rotated to a position with a 45° included angle with the initial state before rotation.

[0050] When rotated to a suitable position, for example, the initial state of the photovoltaic sheet 1 is 30°, then the current angle position can be fixed by inserting a positioning pin in the second shaft seat 362 and / or the third shaft seat 363, so as to facilitate the observation of the photovoltaic sheet 1. When it is needed to return the photovoltaic sheet 1 to the initial state, the positioning pin is removed, and the rotating screw is rotated to rotate the photovoltaic sheet 1 to the state perpendicular to the horizontal ground.

[0051] In order to facilitate the movement and positioning of the photovoltaic module color difference visual contrast device, the trolley universal wheel 44 is arranged below the trolley arc-shaped rail 42, and the trolley positioning wheel 45 is arranged below the rotating assembly.

[0052] Finally, it should be noted that: the above only describes the preferred embodiments of the utility model, and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
