Detailed Description

The present invention will be further described in detail with reference to the following specific examples:

as shown in fig. 1, a dustpan-type photovoltaic tile includes a plurality of photovoltaic modules 1, a water blocking connector 2 and an edge span connector 3.

Referring to fig. 2, the photovoltaic modules 1 are installed on a roof purline 01 and are arranged in an inclined manner, as shown in fig. 3, each photovoltaic module 1 comprises a glass plate 11 and a plurality of photovoltaic cells 12, and white glass 13 is arranged at the upper end of each glass plate 11; each photovoltaic module 1 is provided with a frame 4 on the periphery, as shown in fig. 4, the frame 4 comprises an upper frame 41, a lower frame 42, a left frame 43 and a right frame 44 which enclose a trapezoid, and the upper end size (d1) of the enclosed trapezoid structure is at least 4mm larger than the lower end size (d 2); wherein, left frame 43 and right frame 44 and glass board 11 side joint, go up frame 41 and lower frame 42 and all be in photovoltaic module 1 below, glass board 11 below promptly.

The trapezoidal structure of the frame 4 is designed to facilitate the effective lap joint between the adjacent photovoltaic modules 1 distributed along the longitudinal direction, that is: the small opening end of the upper frame body 4 can be inserted and matched with one side of the large opening end of the lower frame body 4; the specific structure of the frame 4 is mainly as follows:

referring to fig. 4, the left frame 43 and the right frame 44 are symmetrically arranged and are integrally structured, and as shown in fig. 7-10, the left frame and the right frame include a section 431 with a cross-section shaped like a Chinese character 'kou', an upper supporting plate 432 and a lower supporting plate 433 which extend from the upper end and the lower end of the section 431 to the same side in sequence, a vertical plate 434 which extends from the upper end of the section 431 to the upper side, an upper clamping plate 435 which is perpendicular to the vertical plate 434, and a clamping strip 436 which extends from the upper clamping plate 435 to the upper side; a groove 437 for clamping the photovoltaic component 1 is formed between the upper clamping plate 435 and the upper supporting plate 432; as shown in fig. 8 and 11, upper ends of the left frame 43 and the right frame 44 are cut off with the upper snap plate 435 and the snap strip 436 (grid hatched area in fig. 8) to form an upper notch (area corresponding to the thick solid line in fig. 11); as shown in fig. 10 and 12, the lower end portion is cut out by the sectional material 431 and the lower supporting plate 433 (the grid hatched area in fig. 10) to form a lower notch; the extension structure (the thick solid line portion in fig. 12) corresponding to the lower notch can be effectively inserted into the upper notch, so as to realize the overlapping of the photovoltaic modules 1 distributed along the longitudinal direction.

As shown in fig. 13 and 14, the upper end surfaces of both sides of the upper frame 41 have first notches 411 for the upper support plate 432 to fit, and the lower end surfaces of both sides have second notches 412 for the lower support plate 433 to fit; after the two ends of the upper frame 41 are matched with the left frame 43 and the right frame 44, the two ends are locked and fixed through bolts.

As shown in fig. 15 and 16, the upper end surfaces of both sides of the lower frame 42 have third notches 421 for the upper supporting plate 432 to fit, the both sides have fourth notches 422 for the sectional material 431 to fit, and the lower supporting plate 433 at the corresponding mounting position is cut away; the two ends of the lower frame 42 are locked and fixed by bolts after being matched with the left frame 43 and the right frame 44.

It should be noted that, in order to ensure that the photovoltaic modules 1 distributed along the longitudinal direction can be effectively lapped, the height of the lower frame 42 along the end surface perpendicular to the photovoltaic modules 1 is greater than the height of the upper frame 41, so that the lower end of the frame 4 is raised and can be smoothly lapped above the frame 4 of the next layer, as shown in fig. 17, that is: the corresponding extending structure (the thick solid line part in fig. 12) at the lower notch can be effectively inserted at the upper notch; meanwhile, the height of the upper frame 41 is set to be d3, the distance between the upper end surface of the lower frame 42 and the lower end surface of the fourth notch is set to be d4, and d3 is d4 to ensure matching.

Because the frame body 4 encloses a trapezoid structure, the corresponding glass plate 11 can be arranged in the following two ways:

firstly, the glass plate 11 is in a rectangular structure, and as shown in fig. 5, gaskets 5 are arranged between two sides of the upper end of the glass plate 11 and the groove bodies 437 of the left frame 43 and the right frame 44 respectively, as shown in fig. 6, each gasket 5 is provided with a straight edge 51 and a bevel edge 52, a hole is formed in the middle, wherein the straight edge 51 is attached to the outer wall of the photovoltaic module 1, the bevel edge 52 is attached to the inner wall of the groove body 437, and the groove is formed in the middle of the bevel edge 52; by additionally arranging the gasket 5, the equal gaps on the two sides of the glass plate 11 can be ensured, and the gap for inserting the previous photovoltaic module 1 is supplemented.

Secondly, the glass plate 11 is in a trapezoidal structure, and two side edges of the glass plate are directly abutted against the inner wall of the groove body 437.

After the photovoltaic module 1 is installed in the frame 4, the two side edges can be clamped with the groove body 437 by conventional methods such as gluing and the like, and the white glass 13 at the upper end of the glass plate 11 is opposite to the upper notch; based on the structural design of the frame body 4, in the photovoltaic assemblies 1 distributed along the longitudinal direction, the lower end of the photovoltaic assembly 1 positioned above is lapped with the white glass 13 at the upper end of the photovoltaic assembly 1 positioned below, so that the lower gap parts of the left frame 43 and the right frame 44 are matched with the upper gap parts, and the water-blocking adhesive tape 14 arranged along the transverse direction is also arranged in the lapping region, and two water-blocking adhesive tapes 14 are arranged in the embodiment to play a role of double water blocking; to ensure that the glass sheets 11 are lapped but not stressed, the height difference between the upper frame 41 and the lower frame 42 is equal to or slightly higher than the lapping height difference of the glass sheets 11 plus the height of the water-blocking tape 14.

As shown in fig. 18 and 19, the adjacent photovoltaic modules 1 distributed along the transverse direction are fixedly installed by using the water blocking connectors 2; the water-blocking connecting piece 2 comprises a longitudinal beam 21, a plurality of pressing blocks 22, self-tapping self-drilling screws 23 and a cover plate 24; the longitudinal beams 21 are fixed on the purlines 01 and are used for supporting a left frame 43 and a right frame 44 on the side edges of two adjacent groups of photovoltaic modules 1, and the length direction of the upper end surface is inwards concave to form a groove 211; two ends of the pressing block 22 are pressed on the upper end faces of the section bars 431 of the left frame 43 and the right frame 44, and the self-tapping self-drilling screw 23 is positioned and penetrates through the groove 211 so as to connect the pressing block 22 and the longitudinal beam 21; the cover plate 24 is connected with the pressing block 22, two ends of the cover plate are respectively covered on the left frame 43 and the right frame 44, the end portion of the cover plate is provided with a first water-blocking adhesive tape 25, the first water-blocking adhesive tape 25 is attached to the upper plane of the photovoltaic assembly 1, the upper end portion of the clamping strip 436 is further connected with a second water-blocking adhesive tape 26, and the second water-blocking adhesive tape 26 is attached to the inner surface of the cover plate 24.

The first water-blocking adhesive tape 25 and the second water-blocking adhesive tape 26 mainly play a role in blocking water, but water seepage still occurs, and the reason for water seepage mainly comes from: firstly, when the external wind is strong, the air pressure at the outer side end of the cover plate 24 is lower than the internal air pressure, so that the rainwater is easy to infiltrate; secondly, capillary holes are certainly formed in the structures of the first water-blocking adhesive tape 25 and the second water-blocking adhesive tape 26, and water seepage is easily caused based on the siphon principle; therefore, even if a small amount of rainwater infiltrates through the first water blocking tape 25, the infiltrated water can be discharged in the longitudinal direction along the region of the outer side end of the clamping strip 436 due to the blocking of the clamping strip 436; when a small amount of rainwater permeates through the second water-blocking adhesive tape 26, the permeated rainwater can be discharged along the longitudinal direction along the area formed between the clamping strip 436 and the vertical plate 434 due to the blocking of the vertical plate 434; therefore, the first water-blocking adhesive tape 25 and the second water-blocking adhesive tape 26 perform a double water-blocking function, and even if a small amount of water permeates into the water-blocking adhesive tape, the water can be drained by attaching to the structures of the left side frame 43 and the right side frame 44.

Meanwhile, due to the height difference between the upper frame 41 and the lower frame 42, as shown in fig. 17, included angles exist between the left frame 43 and the right frame 44 and the corresponding longitudinal beams 21, so that a gap 6 is formed, and the gap 6 is gradually increased from the side where the upper frame 41 is located to the side where the lower frame 42 is located; and because when installing the briquetting 22, under the effect of self tapping self-drilling screw 23, left frame 43 and right frame 44 can produce the deformation, and make photovoltaic module 1 produce the deformation, therefore, be provided with cushion 61 between left frame 43 and right frame 44 and longeron 21, self tapping self-drilling screw 23 runs through cushion 61, and connect briquetting 22 and longeron 21, this cushion 61 mainly plays the supporting role to avoid photovoltaic module 1 to take place the deformation and influence life.

The cover plates 24 are reversely buckled between the joints of the adjacent photovoltaic modules 1, the adjacent photovoltaic modules 1 distributed along the transverse direction share one cover plate 24, and the cover plates 24 distributed along the longitudinal direction are also combined in an overlapping manner, as shown in fig. 20, the lower end part of the cover plate 24 positioned above is overlapped with the upper end part of the cover plate 24 positioned below, and a flashing sealing head 241 is arranged at the overlapping position.

As shown in fig. 21, the edge along the longitudinal direction is provided with an edge span connector 3, the edge span connector 3 includes a longitudinal beam 21, a plurality of edge span press blocks 31, a self-tapping self-drilling screw 23, an edge span cover plate 32 and an edge span connecting cover 33, the longitudinal beam 21 is supported by a left frame 43/a right frame 44 on the side of the photovoltaic module 1, one end of the edge span press block 31 is pressed on the left frame 43/the right frame 44, the other end extends downwards and is pressed on the upper end surface of the longitudinal beam 21, and the self-tapping self-drilling screw 23 is connected with the edge span press blocks 31 and the longitudinal beam 21; the side span cover plate 32 is connected with the side span pressing block 31, and one side end part extends and covers the left frame 43/the right frame 44; the side span connecting cover 33 covers the side span cover plate 32 and is fixed on the wall surface.

The frame body 4 is designed into a trapezoidal structure, so that the photovoltaic modules 1 distributed longitudinally can be conveniently and effectively lapped, and compared with the traditional installation mode, the cost is saved by 10%; the photovoltaic modules 1 distributed along the transverse direction are connected by the water blocking connectors 2, the double water blocking effect is achieved through the design of the first water blocking adhesive tape 25 and the second water blocking adhesive tape 26, and the service life of the whole structure can reach 25-30 years.
