DETAILED DESCRIPTION

[0039] Embodiment 1

[0040] refer to Figure 1 , Figure 3 and Figure 5 A solar photovoltaic power generation component fault detection device includes a mounting bracket 401 for mounting an infrared imager 501, and also includes a walking mechanism for driving the mounting bracket 401 to move, that is, the infrared imager 501 is driven to move by the walking of the walking mechanism.

[0041] In this embodiment, the walking mechanism includes a walking bracket 101, and two walking wheel groups 102 are arranged on the walking bracket 101. The walking wheel group 102 includes a movable connecting rod 1022 and a plurality of walking rollers 1021, wherein one of the walking wheel groups 102 is used to roll along the upper side of the photovoltaic panel 701, and the other walking wheel group 102 is used to roll along the upper edge of the front of the photovoltaic panel 701, that is, the walking rollers 1021 of the two walking wheel groups 102 are perpendicular to each other. It is easy to understand that since the photovoltaic panel 701 is usually installed at a certain angle (usually about 40°), when in use, one of the walking wheel groups 102 is hung on the upper side of the photovoltaic panel 701, and the other walking wheel group 102 is pressed on the upper edge of the front of the photovoltaic panel 701, and is hung on the photovoltaic panel 701 under the action of the detection device's own gravity (reference Fig.10 ).

[0042] The walking roller 1021 is provided with an eccentric pin 1023, and the movable connecting rod 1022 is respectively connected to each eccentric pin 1023. In this way, in a walking wheel group 102, the rotation of one walking roller 1021 can drive other walking rollers 1021 to rotate together. It is easy to understand that a connecting shaft is provided at the center of each walking roller 1021, and the connecting shaft is rotatably connected to the walking bracket 101.

[0043] Further, a driving shaft 104 is provided at the center of a walking roller 1021 of one walking wheel group 102, and the driving shaft 104 is connected to a driving motor 103. It is easy to understand that in actual applications, the driving motor 103 should be used in conjunction with a reducer (not shown). A driven shaft 105 is provided at the center of a walking roller 1021 of another walking wheel group 102, and the driven shaft 105 is connected to the driving shaft 104 in a transmission manner. In this way, the driving motor 103 can drive the two walking wheel groups 102 to rotate synchronously. Specifically, a driven bevel gear is provided on the driven shaft 105, and a driving bevel gear is provided on the driving shaft 104. The driven bevel gear meshes with the driving bevel gear. It should be understood that the transmission ratio of the driven bevel gear to the driving bevel gear is 1 to ensure that the two wheel groups rotate synchronously.

[0044] When in use, the driving motor 103 is started, driving the walking rollers 1021 of the two walking wheel groups 102 to rotate synchronously, wherein one walking wheel group 102 rolls along the upper side of the photovoltaic panel 701, and the other walking wheel group 102 is used to roll along the upper edge of the front of the photovoltaic panel 701, so that the walking mechanism can move along the photovoltaic panel 701, thereby driving the infrared imager 501 to move. Compared with the prior art, the present invention improves automation, so that the detection process does not require physical labor by the detection personnel, and is more convenient to use.

[0045] It is worth noting that, based on the above, if there are debris (such as large branches and leaves, thick bird droppings, etc.) on the upper edge of the front of the photovoltaic panel 701, the walking mechanism may easily cause the walking wheel set 102 hanging on the side of the photovoltaic panel 701 to fall off when walking, thereby causing the detection device to fall off. For this reason, the present invention is set up as follows: Figure 3 , Figure 4 and Figure 5 The walking bracket 101 is also provided with an anti-slip wheel set 201, which includes a plurality of anti-slip wheels 2011 for abutting the back of the photovoltaic panel 701, and the anti-slip wheels 2011 are rotatably arranged on the support 2012, and the support 2012 is elastically connected to the walking bracket 101, so that the anti-slip wheels 2011 can be passively rotated to assist walking. If there are debris on the upper edge of the front of the photovoltaic panel 701, the anti-slip wheels 2011 can be squeezed to pass over the debris, and it also avoids the walking wheel set 102 hanging on the side of the photovoltaic panel 701 from falling off and causing the detection device to fall off.

[0046] In this embodiment, the elastic connection method of the anti-slip wheel 2011 is as follows: at least two guide rods 2014 are fixedly connected to the support 2012, and the guide rods 2014 are slidably arranged on the walking bracket 101. It is easy to understand that the two guide rods 2014 can prevent the anti-slip wheel 2011 from rotating. A limit block 2015 is provided on the guide rod 2014 to limit the guide rod 2014 from slipping off the walking bracket 101. A spring 2013 is sleeved on the guide rod 2014, and the spring 2013 is pressed between the support 2012 and the walking bracket 101. That is, if there are debris on the upper edge of the front of the photovoltaic panel 701, the spring 2013 is compressed. After passing over the debris, the spring 2013 is restored to reset the detection device and keep hanging on the photovoltaic panel 701. Further, the stopper 2015 is connected with the guide rod 2014 by threading, and is arranged in this way, so as to be convenient to adjust the preload of the spring 2013, and to avoid the anti-slip wheel 2011 from being too tight. In practical applications, the stopper 2015 can be replaced by a nut.

[0047] refer to Figure 2 and Figure 6 The detection device also includes a distance adjustment mechanism for adjusting the distance between the infrared imager 501 and the walking mechanism. It is worth noting that since some photovoltaic power generation components are in one row, some are in two rows, and some are in three rows or even more rows, by adjusting the position of the infrared imager 501 relative to the walking mechanism, it is possible to complete the detection of photovoltaic panels 701 in different rows with only one infrared imager 501, which greatly saves costs compared to the prior art that uses multiple infrared imagers 501 to complete the detection.

[0048] The distance adjustment mechanism includes an adjustment bracket 301, which is fixed to the walking mechanism by screws, and an adjustment screw rod 302 is rotatably provided on the adjustment bracket 301, and one end of the adjustment screw rod 302 is connected to a distance adjustment motor 304, and the adjustment screw rod 302 is threadedly matched with a slider 303, and the mounting bracket 401 is fixedly connected to the slider 303, and the mounting bracket 401 is slidably connected to the adjustment bracket 301. In this way, the distance adjustment screw rod 302 is driven to rotate by the distance adjustment motor 304, so that the slider 303 can be moved along the screw rod 302, thereby changing the position of the mounting bracket 401, and the position adjustment of the infrared imager 501 relative to the walking mechanism can be realized to adapt to photovoltaic panels 701 of different rows. It is easy to understand that the distance adjustment motor 304 should be used in conjunction with a reducer (not shown).

[0049] In this embodiment, reference Figure 7The specific method of sliding connection between the mounting bracket 401 and the adjusting bracket 301 is as follows: the mounting bracket 401 is fixedly connected with a T-shaped slide bar 402, the adjusting bracket 301 is provided with a T-shaped slide groove 3011 that matches the T-shaped slide bar 402, and the T-shaped slide bar 402 is fixedly connected with the slider 303. The above-mentioned fixed connection method is not limited, such as welding and screw connection. Of course, in other embodiments, the sliding connection between the mounting bracket 401 and the adjusting bracket 301 can also be realized by other methods, such as the mounting bracket 401 and the adjusting bracket 301 are connected by a guide rail.

[0050] refer to Figure 2 , Figure 8 and Fig. 9 On the basis of the above, a mounting plate 409 is provided on one side of the mounting bracket 401 of this embodiment, and the mounting plate 409 is provided with a mounting hole. The infrared imager 501 is installed in the mounting hole, and a height adjustment mechanism for adjusting the height of the mounting plate 409 relative to the front of the photovoltaic panel 701 is provided on the mounting bracket 401. Such a configuration facilitates the adjustment of the height of the infrared imager 501, thereby adjusting its camera range.

[0051] The height adjustment mechanism includes two rotating shafts 403, two first swing rods 404, two second swing rods 405 and a driving assembly; the two rotating shafts 403 are rotatably set on the mounting bracket 401, one end of the first swing rod 404 is fixedly connected to one of the rotating shafts 403, and the other end of the first swing rod 404 is hinged to the mounting plate 409, one end of the second swing rod 405 is fixedly connected to the other rotating shaft 403, and the other end of the second swing rod 405 is hinged to the mounting plate 409, and the first swing rod 404 and the second swing rod 405 have the same length. It is easy to understand that the first swing rod 404 and the second swing rod 405 are staggered to avoid interference.

[0052] One of the rotating shafts 403 is connected to the driving component, for example, the driving component is connected to the rotating shaft 403 connected to the first swing arm 404. When the driving component drives the rotating shaft 403 to rotate, the first swing arm 404 can be driven to rotate, and the second swing arm 405 and the other rotating shaft 403 will also rotate accordingly. Since the first swing arm 404 and the second swing arm 405 have the same length, the state of the mounting plate 409 is always parallel to the previous state, and only the position changes relative to the previous state, that is, the height relative to the front of the photovoltaic panel 701 changes when in use. In this way, the height of the infrared imager 501 is also changed.

[0053] In this embodiment, the driving assembly includes a height adjustment motor 406, a worm gear 407 and a worm 408, the worm gear 407 is fixedly connected to one of the rotating shafts 403, the height adjustment motor 406 is mounted on the mounting bracket 401, the worm 408 is connected to the height adjustment motor 406 and meshes with the worm gear 407, and in this way, the self-locking property of the worm gear 408 and the worm gear 407 structure is utilized to ensure the reliability of the height adjustment of the infrared imager 501 and avoid changes during use. It is easy to understand that in actual applications, the height adjustment motor 406 should be used in conjunction with a reducer (not shown).

[0054] On the basis of the above, a number of auxiliary rollers 601 are provided on the adjustment bracket 301 and the installation bracket 401. On the one hand, the auxiliary rollers 601 assist in walking, and on the other hand, the auxiliary rollers 601 ensure that the two ends of the detection device are at the same height relative to the front of the photovoltaic panel 701, that is, to ensure that the installation plate 409 is parallel to the photovoltaic panel 701, and the infrared imager 501 is perpendicular to the photovoltaic panel 701.

[0060] S4, detection: drive the walking mechanism to walk along the photovoltaic panels 701, and detect the first row of photovoltaic panels 701. Since the width of the camera area of ​​the infrared imaging covers all areas in the width direction of a row of photovoltaic panels 701, the detection device moves in one direction once, that is, the detection of a row of photovoltaic panels 701 is completed; after the detection of the first row of photovoltaic panels 701 is completed, the position of the mounting bracket 401 is adjusted by the distance adjustment mechanism, so that the infrared imager 501 can take pictures of the second row of photovoltaic panels 701, even if the mounting bracket 401 slides along the adjustment bracket 301, so that the infrared rays are roughly in the middle position of the width direction of the second row of photovoltaic panels 701, the walking mechanism is driven again to walk in the opposite direction along the photovoltaic panels 701, so that the second row of photovoltaic panels 701 can be detected, and this is repeated until all rows of photovoltaic panels 701 are detected. That is, in this embodiment, the detection of all rows of photovoltaic panels 701 is completed by the reciprocating movement of the detection device and the adjustment of the position of the infrared imager 501 each time the walking. The method provided in this embodiment is suitable for the situation where there are many rows of photovoltaic panels 701.

[0065] It is easy to understand that the above steps are the same as the method provided in Example 2, that is, the detection device provided in Example 1 is also used. The method provided in this embodiment is different from that in Example 2 in the following process:

[0066] S3.

For example, if there are three rows of photovoltaic panels 701, first adjust the position of the mounting bracket 401 through the distance adjustment mechanism, so that the infrared imager 501 is located in the middle of the second row (i.e., the middle row) in the width direction, and then adjust the height of the infrared imager 501 through the height adjustment mechanism, so that its imaging range covers all areas in the width direction of the three rows of photovoltaic panels 701;

[0067] S4. Detection: drive the walking mechanism to walk along the photovoltaic panels 701 to complete the detection of all photovoltaic panels 701 at one time. It can be seen that the detection method provided in this embodiment can complete the detection of all photovoltaic panels 701 in one walk after adjusting the infrared imager 501. The method provided in this embodiment is suitable for the situation where the number of rows of photovoltaic panels 701 is small.
