[0027] The cable of the photovoltaic power generation device 100 of the embodiment of the present application passes through the positioning slot and the through slot 41, the terminal of the end of the cable is integratedly installed in the box body 4, the cable can be clamped and positioned by the relatively close first and second positioning blocks 52 and 53, the stability of the cable can be improved, meanwhile, the water absorption member 51 is arranged at the position where the first and second positioning blocks 52 and 53 contact the cable, the water absorption member 51 can improve the sealing performance of the connection between the cable and the box body 4, prevent water vapor from penetrating into the box body 4, and can also absorb the water vapor inside the box body 4, so that the terminal in the box body 4 is in a dry environment, the probability of electrochemical corrosion and oxidation short circuit of the terminal is reduced, and the service life of the cable and the terminal is prolonged.
[0028] Specifically, as shown in Figure 1 and Figure 2 , the mounting rack 1 is in the shape of a rectangle as a whole and is arranged to be inclined to the horizontal plane, the length direction of the mounting rack 1 is inclined to the horizontal plane, and the width direction of the mounting rack 1 is parallel to the horizontal plane; the mounting rack 1 is composed of a plurality of rectangular frames, each rectangular frame has a rectangular slot 11 which forms the above-mentioned mounting portion, the photovoltaic panel 2 is placed in the rectangular slot 11, and then the edge of the photovoltaic panel 2 and the rectangular frame is fixed by the clamping member 12, so that the stable connection of the photovoltaic panel 2 and the mounting rack 1 is realized, the clamping member 12 allows the slight displacement caused by thermal expansion and cold contraction while ensuring the fastening of the connection between the photovoltaic panel 2 and the mounting rack 1, prevents the photovoltaic panel 2 from cracking due to temperature stress, and improves the stability of the photovoltaic panel 2. In the actual installation process, a plurality of photovoltaic panels 2 can be first fixed with the mounting rack 1 to form a modular connection, which is convenient for on-site rapid installation or replacement.
[0029] As shown in Figure 2As shown, the support assembly 3 comprises two connecting rods 31, two vertical rods 32, two support inclined rods 33 and a bottom plate 34. The two connecting rods 31 extend along the length direction of the mounting rack 1 and are arranged near the two sides of the mounting rack 1 respectively along the width direction of the mounting rack 1. The two connecting rods 31 are fixed to the lower side of the mounting rack 1 by bolts. The two vertical rods 32 extend vertically. The upper ends of the two vertical rods 32 are connected to the two connecting rods 31 respectively and can be adjusted in rotation relative to the connecting rods 31. The lower ends of the two vertical rods 32 are connected to a connecting plate 93 by bolts and can be adjusted in rotation relative to the connecting plate 93. The connecting plate 93 is long and extends along the width direction of the mounting rack 1. The two vertical rods 32 and the connecting plate 93 form a support group. There are two support groups. The two support groups are arranged near the two sides of the mounting rack 1 respectively along the length direction of the mounting rack 1. The two support groups can provide support to the mounting rack 1 from the two sides of the mounting rack 1 simultaneously. By adjusting the height of the two support groups, the inclination angle of the mounting rack 1 can be adjusted, and then the inclination angle of the photovoltaic panel 2 can be adjusted, so that the power generation efficiency of the photovoltaic panel 2 is maximized.
[0030] The support group arranged at the higher side of the mounting rack 1 further comprises the above-mentioned support inclined rod 33. The support inclined rod 33 is V-shaped with the vertical rod 32. One end of the support inclined rod 33 is connected to the bottom plate 34 by a bolt and can be adjusted in rotation relative to the bottom plate 34. The other end of the support inclined rod 33 is connected to the middle part of the connecting rod 31 by a bolt and can be adjusted in rotation relative to the connecting rod 31.
[0031] Thus, the vertical rod 32, the support inclined rod 33 and the connecting rod 31 form a triangular stable structure, which can provide stable support to the mounting rack 1 and the photovoltaic panel 2 and improve the wind resistance and resistance change ability of the photovoltaic power generation device 100. In addition, by adjusting the rotation of the vertical rod 32 relative to the connecting rod 31 and adjusting the connection position of the support inclined rod 33 and the middle part of the connecting rod, the inclination angle of the mounting rack 1 can be changed, the adaptability of the device to different terrains is improved, and the device is more suitable for installation in mountainous areas, rooftops and other uneven sites.
[0032] As shown in Figs. 1 and 2, Figure 2 and Figure 3 The outer contour of the box body 4 is rectangular. The box body 4 is installed on the lower side of the mounting rack 1. The side wall of the box body 4, which is perpendicular to the lower side of the mounting rack 1 and is arranged upward, has the above-mentioned through slot 41. The cable positioning assembly 5 is arranged on the side wall of the box body 4. By passing the cable out of the side wall of the box body 4, the operation is more convenient.
[0033] The box 4 has a cavity 42 for accommodating wiring terminals. The through groove 41 communicates with the cavity 42. The cavity 42 provides a space for centralized cable management to avoid messy wiring. The side wall of the box 4 away from the mounting frame 1 is provided with an opening door 43. The opening door 43 has an open state and a closed state. When the opening door 43 is closed, it forms a sealed cavity 42. When the opening door 43 is open, the side of the box 4 away from the mounting frame 1 forms an inspection port. The inspection port can be used to inspect and maintain the various components inside the box 4 to ensure the continuous operation and power generation efficiency of the photovoltaic power generation device 100.
[0034] Among them, the opening and closing door 43 is electrically controlled, which is a technology well known to those skilled in the art and will not be described in detail here.
[0035] In some embodiments, the cable positioning assembly 5 further includes a fixing base 54 and a plurality of first springs 55. The fixing base 54 is connected to the housing 4. The first positioning block 52 and the second positioning block 53 are both slidably connected to the fixing base 54. At least one first spring 55 has its two ends connected to the first positioning block 52 and the fixing base 54 respectively, so as to apply a spring force toward the second positioning block 53 to the first positioning block 52. At least one first spring 55 has its two ends connected to the second positioning block 53 and the fixing base 54 respectively, so as to apply a spring force toward the first positioning block 52 to the second positioning block 53.
[0036] In some embodiments, the first positioning block 52 has a first insertion portion arranged toward the second positioning block 53, and the second positioning block 53 has a second insertion portion arranged toward the first positioning block 52, wherein the first insertion portion and the second insertion portion are inserted into each other.
[0037] Specifically, such as Figure 3 and Figure 4 As shown, there are two fixing seats 54. Both fixing seats 54 are located in the through groove 41 and are fixedly connected to the box body 4. The fixing seats 54 are tightly fitted and sealed to the groove wall of the through groove 41. The two fixing seats 54 are arranged opposite to each other. Both fixing seats 54 have mounting grooves 541. The first positioning block 52 and the second positioning block 53 are slidably engaged in the mounting grooves 541 of the two fixing seats 54. The first positioning block 52 has a first positioning surface 522 facing the second positioning block 53. The second positioning block 53 has a second positioning surface 532 facing the first positioning block 52. The first positioning surface 522 and the second positioning surface 532 are both arc-shaped. The first positioning surface 522 and the second positioning surface 532 form the positioning groove.
[0038] like Figure 4As shown, there are multiple first springs 55, which are divided into two groups. The two groups of first springs 55 are respectively installed in the mounting slots 541 of the two fixed seats 54. The installation structure of the two groups of first springs 55 in the two fixed seats 54 is the same. Taking the fixed seat 54 connected to the first positioning block 52 as an example: each group includes two first springs 55. The extension and retraction direction of the first springs 55 is consistent with the sliding direction of the first positioning block 52. One end of the first spring 55 is fixedly connected to the first positioning block 52, and the other end of the first spring 55 is fixedly connected to the groove wall of the mounting slot 541. The first spring 55 is used to apply a spring force to the first positioning block 52 toward the second positioning block 53. Similarly, the first spring 55 in the other fixed seat 54 is used to apply a spring force to the second positioning block 53 toward the first positioning block 52.
[0039] The cable is passed through the through slot 41 and the positioning slot. Under the elastic force of the two sets of first springs 55, the first positioning block 52 and the second positioning block 53 move closer to each other. The first positioning surface 522 and the second positioning surface 532 are tightly attached to the cable, which can stably clamp the cable without damaging it. This achieves the fixation of the cable and ensures its stability.
[0040] The first positioning block 52 has a plug slot 521 facing the second positioning block 53, and the second positioning block 53 has a plug block 531 facing the first positioning block 52. When the first positioning block 52 and the second positioning block 53 are close to each other and clamp the cable, the plug block 531 is inserted into the plug slot 521, which can further improve the stability of the cable and reduce the risk of the cable loosening or falling off during use. In addition, the cable positioning component 5 can also meet the fixing requirements of cables of different diameters.
[0041] like Figure 4 As shown, the absorbent component 51 is also arc-shaped and matches the shape of the first positioning surface 522 and the second positioning surface 532. There are two absorbent sheets, which are respectively attached to and connected to the first positioning surface 522 and the second positioning surface 532. The first positioning block 52 and the second positioning block 53 are clamped to the cable by the absorbent sheets, which can play a sealing role between the positioning groove and the cable, preventing water vapor from seeping into the box 4. At the same time, they can absorb the water vapor inside the box 4, making the box cavity 42 a dry environment, reducing the probability of electrochemical corrosion of the wiring terminals inside the box cavity 42, and extending its service life.
[0042] Optionally, the absorbent element 51 is made of silica gel drying sheet.
[0043] In some embodiments, the photovoltaic power generation device 100 further includes a drying component 6, the housing 4 has a cavity 42, the drying component 6 is disposed in the cavity 42 and connected to the cavity wall of the cavity 42.
[0044] In some embodiments, the drying assembly 6 includes a connecting cover 61, a connecting seat 62, a drying box 63, and a drying element 64 for absorbing water. The connecting cover 61 is connected to the cavity wall of the box cavity 42, the connecting seat 62 is disposed on the lower side of the connecting cover 61 and connected to the connecting cover 61, the drying box 63 has a drying cavity, the drying element 64 is disposed in the drying cavity, and the drying box 63 is slidably connected to the connecting seat 62.
[0045] Optionally, the drying element 64 includes a honeycomb skeleton structure and a highly absorbent part. The honeycomb skeleton structure is made of polyurethane or inorganic fibers, and the highly absorbent part is made of salts or modified silica gel. The highly absorbent part fills the pores of the honeycomb skeleton structure or is fixed to the wall of the honeycomb groove of the honeycomb skeleton structure to form multiple honeycomb grooves with highly absorbent function.
[0046] Therefore, the porous structure of the drying element 64 can be used to expand the moisture absorption area and improve the dilution efficiency.
[0047] In other embodiments, the drying element 64 can also be directly set as a granular desiccant, such as activated alumina, molecular sieve, silica gel, etc.
[0048] In some embodiments, the connecting cover 61 has a cover cavity and a first opening 611 arranged toward the connecting seat 62. The connecting seat 62 has a receiving groove with a second opening 621 arranged toward the connecting cover 61. The first opening 611 communicates with the second opening 621. The groove wall of the receiving groove arranged opposite to the second opening 621 has a plurality of second vent holes 622. The drying box 63 is slidably disposed in the receiving groove. The side wall of the drying box 63 near the second opening 621 has a third opening 631. The side wall of the drying box 63 arranged opposite to the third opening 631 has a plurality of first vent holes.
[0049] Specifically, such as Figure 3 and Figure 5 As shown, the connecting cover 61 is conical. The larger end of the connecting cover 61 (i.e., the upper end of the connecting cover 61) fits against the upper cavity wall of the box cavity 42 and is fixedly connected to the cavity wall of the box cavity 42. The connecting seat 62 is located on the lower side of the connecting cover 61 and is fixedly connected to the smaller end of the connecting cover 61 (i.e., the lower end of the connecting cover 61). The connecting seat 62 has a receiving groove for installing the drying box 63. The drying box 63 is located in the receiving groove and slides in the receiving groove. The receiving groove is provided with a guide rail for providing sliding support for the drying box 63, thereby realizing the pulling action of the drying box 63. When it is necessary to replace the drying element 64, the drying box 63 is pulled out from the receiving groove to replace the drying element 64. In addition, a handle 632 is also connected to the outside of the drying box 63 so that the operator can pull out the drying box 63.
[0050] like Figure 5As shown, the lower end of the connecting cover 61 is open to form the first opening 611, the upper wall of the accommodating groove is open to form the second opening 621, the upper side wall of the drying box 63 is open to form the third opening 631, and the lower side wall of the drying box 63 is used to form the drying element 64. The lower side wall of the drying box 63 has multiple evenly distributed first vent holes, and the lower wall of the accommodating groove has multiple evenly distributed second vent holes 622. Thus, the first opening 611, the second opening 621, the third opening 631, the first vent hole, and the second vent hole 622 are connected in sequence, allowing moisture in the box cavity 42 to enter the drying box 63 through the first vent hole and the second vent hole 622 and be drawn into the drying element 64, thereby keeping the terminals in the box cavity 42 in a dry environment and improving their service life.
[0051] In some embodiments, the photovoltaic power generation device 100 further includes a stop assembly 7, which includes a fixed cylinder 71, a stop rod 72, and an elastic member 73. The fixed cylinder 71 is disposed on the lower side of the connecting seat 62 and connected to the connecting seat 62. The stop rod 72 slidably passes through the fixed cylinder 71, and the upper end of the stop rod 72 extends through the connecting seat 62 to the receiving groove. The elastic member 73 is used to apply an upward elastic force to the stop rod 72 so that the upper end of the stop rod 72 stops against the drying box 63.
[0052] Optionally, the elastic element 73 is a stop spring.
[0053] Specifically, such as Figure 3 and Figure 6 As shown, there are multiple stop components 7, which are arranged in a matrix on the lower side of the connecting seat 62. The fixing cylinder 71 is perpendicular to the lower side of the connecting seat 62 and is fixedly connected to the connecting seat 62. The stop rod 72 is slidably inserted through the fixing cylinder 71, and the upper end of the stop rod 72 passes through the lower side wall of the connecting seat 62 and abuts against the lower side wall of the drying box 63. The stop spring is fitted on the stop rod 72 and is located inside the fixing cylinder 71. The stop spring is used to apply a spring force to the stop rod 72 toward the drying box 63, so that the stop rod 72 is stably abutted against the junction box. The stop rods 72 of multiple stop components 7 abut against the lower side wall of the drying box 63 at the same time, which can improve the stability of the drying box 63 in the connecting seat 62.
[0054] In some embodiments, the housing 4 is slidably connected to the mounting bracket 1, the mounting bracket 1 is connected to the slide rail 13, the housing 4 is connected to the slide base 8, and the slide base 8 is slidably connected to the slide rail 13.
[0055] Specifically, such as Figure 2 As shown, a slide rail 13 is fixedly connected to the lower side of the mounting bracket 1. The slide rail 13 extends along the length of the mounting bracket 1, and the box 4 can slide along the length of the slide rail 13. This allows for flexible adjustment of the position of the box 4 on the lower side of the mounting bracket 1, which is more conducive to the arrangement of cable routing.
[0056] In some embodiments, the slide rail 13 has a slide groove 131, and the slide seat 8 is disposed in the slide groove 131 and slides in cooperation with the slide groove 131; the photovoltaic power generation device 100 further includes a limiting component 9, the limiting component 9 includes a second spring 92 and a limiting post 91 slidably connected to the slide seat 8, the limiting post 91 has a stop end 911 for stopping against the groove wall of the slide groove 131, and the second spring 92 is used to apply a spring force to the limiting post 91 toward the groove wall of the slide groove 131.
[0057] In some embodiments, the number of limiting posts 91 is multiple, and the limiting component 9 further includes a connecting plate 93 slidably connected to the slide block 8. The multiple limiting posts 91 are all connected to the connecting plate 93. The slide block 8 has a limiting groove 82, and the limiting groove 82 has a first limiting surface 821 and a second limiting surface 822 arranged opposite to each other along the sliding direction of the limiting posts 91 relative to the slide block 8. At least a portion of the connecting plate 93 is arranged between the first limiting surface 821 and the second limiting surface 822.
[0058] Specifically, such as Figure 7 As shown, the slide block 8 is located inside the slide rail 13, and a connecting block 83 is fixedly connected to the outside of the slide block 8. The connecting block 83 is fixedly connected to the outer wall of the box 4, thereby realizing the sliding installation of the box 4 and the slide rail 13.
[0059] There are two limiting components 9, which are arranged opposite to each other on both sides of the slide block 8. The slide block 8 is rectangular and has a receiving groove 81. The receiving groove 81 is arranged through the width of the slide groove 131 to form openings 811 on the two opposite side walls of the slide block 8. The limiting posts 91 of the two limiting components 9 can extend from the two openings 811 and abut against the side wall of the slide groove 131, thereby realizing the positioning of the slide block 8 and the box 4.
[0060] The connecting plate 93 is slidably fitted into the receiving groove 81. The sliding direction of the connecting plate 93 relative to the receiving groove 81 is consistent with the width direction of the slide groove 131. One opening 811 corresponds to two limiting grooves 82. The two limiting grooves 82 are respectively connected to two side walls of the receiving groove 81 that are arranged opposite to each other. The connecting plate 93 is long and narrow, with its two ends passing through the two limiting grooves 82 respectively. The limiting groove 82 has a first limiting surface 821 and a second limiting surface 822 that are arranged opposite to each other along the sliding direction of the connecting plate 93. The first limiting surface 821 and the second limiting surface 822 can limit the sliding range of the connecting plate 93 and prevent the connecting plate 93 and the limiting post 91 from disengaging from the slide seat 8.
[0061] Each limiting assembly 9 contains three limiting posts 91 and three second springs 92. The three limiting posts 91 are evenly distributed along the length of the connecting plate 93 and are fixedly connected to the connecting plate 93. The end of the limiting post 91 away from the connecting plate 93 forms the aforementioned stop end 911. The second spring 92 is located between the connecting plate 93 and the bottom wall of the receiving groove 81. One end of the second spring 92 is fixedly connected to the bottom wall of the receiving groove 81, and the other end of the second spring 92 is fixedly connected to the connecting plate 93. The second spring 92 is used to apply an outward elastic force to the connecting plate 93 and the limiting posts 91, so that the stop end 911 of the limiting post 91 can abut against the side wall of the slide groove 131, thereby realizing the positioning of the slide 8 and the box 4.
[0062] In other embodiments, an electric drive device may be provided between the slide block 8 and the slide rail 13 to drive the slide block 8 to slide, such as a lead screw and nut mechanism or a gear and rack mechanism, which will not be described in detail here.
[0063] In the photovoltaic power generation device 100 of this embodiment, when arranging the electrical cable system, the DC and AC cables of the power generation system are orderly introduced into the box 4 in accordance with the electrical wiring specifications, and the cables are firmly positioned using the cable positioning component 5. It should be noted that the bending radius of the cables must meet the standard to avoid excessive bending. Finally, the water-absorbing component 51 is installed to ensure that the interface parts are effectively moisture-proofed.
[0064] In addition, regular inspections and maintenance are required, such as regularly checking the moisture absorption status of the drying component 64 and the cable fixing status, to ensure the stable operation of the photovoltaic power generation device 100.
