How the photovoltaic module is fixed using the fixing device will be described below. It should be noted that the photovoltaic module generally has a certain installation inclination angle, and the following description will take the case where the short side of the photovoltaic module is parallel to the horizontal plane, and the installation inclination angle is formed between the long side and the horizontal plane. In this case, the short side of the photovoltaic module is in the transverse direction, and the long side of the photovoltaic module is in the longitudinal direction.
First, a plurality of troughs are secured to the purlins of the building roof, wherein the plurality of troughs are arranged in parallel in the lateral direction (i.e., all of the troughs are disposed in the longitudinal direction). Then, the photovoltaic modules are arranged on the water tanks in an overlapping mode, wherein two long frames of one photovoltaic module are respectively arranged on two adjacent water tanks in an overlapping mode, and two adjacent long frames of the two adjacent photovoltaic modules in the transverse direction are arranged on the same water tank in an overlapping mode. When the photovoltaic module long-side framework is arranged on the water tank, the edge of the water guide groove on the back of the long frame is overlapped on the second supporting part of the water tank, and the bottom surface of the long frame is overlapped on the first supporting part, close to one side of the long frame, of the water tank, so that the water tank can stably support the frame of the photovoltaic module and further stably support the photovoltaic module. A certain gap needs to be reserved between two adjacent long frame strips of two photovoltaic modules which are adjacent in the transverse direction, so that the mounting groove in the second supporting part can be exposed. In addition, a certain gap is required to be reserved between two adjacent short frames of two photovoltaic modules which are adjacent in the longitudinal direction. It should be noted here that, by reasonably designing the size of the water tank, the water chute in the long frame can be completely located above the water tank, and the end of the water chute in the short frame can be located above the water tank, so that it can be ensured that water flowing out of the water chutes in the long and short frames can fall into the water tank below. And then, installing a pressing block between two adjacent long frames of two adjacent photovoltaic modules in the transverse direction, specifically, clamping the clamping groove structure of the pressing block on the walls of the water guide grooves of the two adjacent long frames, penetrating a fastening piece through the installation hole in the pressing block body into the installation groove in the second supporting part of the water tank, and fastening until the photovoltaic modules and the water tank are fixed. And finally, installing the slot cover between the adjacent photovoltaic assemblies, specifically, inserting the two fixing parts of the slot cover between two adjacent frames (including the long frame and the short frame) of the adjacent photovoltaic assemblies, and respectively clamping the second clamping mechanisms on the two fixing parts of the slot cover with the first clamping mechanisms in the two adjacent frames of the photovoltaic assemblies, so that the slot cover is fixed.
Implement the utility model provides a photovoltaic module frame and fixing device can realize photovoltaic module's roof installation. In addition, a waterproof function can be realized. In particular, since the groove cover is installed between the adjacent photovoltaic modules, most of water (e.g., rainwater, cleaning water, etc.) can be blocked outside, and only a small amount of water permeates into between the photovoltaic module frame and the groove cover. Because the back of the photovoltaic module frame is provided with the guiding gutter, water permeating into the guiding gutter from the space between the photovoltaic module frame and the groove cover flows into the guiding gutter along the back of the photovoltaic module frame. Furthermore, because the water tank is arranged below the photovoltaic assembly frame, water entering the water guide groove of the photovoltaic assembly frame flows into the water tank below the water guide groove, and finally the water is drained by the water tank. In this way, water does not fall onto the roof of the building. That is, even if the water tank is installed, the water tank will not damage the roof waterproof structure of the building, but the water will not fall on the roof of the building and will be directly drained away by the water tank, so the water leakage phenomenon will not occur on the roof of the building.
There are several implementations of the mounting slots in the sink and the structure of the fasteners. In a preferred embodiment, as shown in fig. 3, the mounting groove 305 is disposed along the length direction of the water tank and penetrates the second supporting portion 304, and the width (W in the drawing) of the mounting groove 305 is within the water tank3Indicated) is greater than the slot width (denoted W in the figure)2Representation). Correspondingly, as shown in fig. 5, the fastener includes a bolt 501 and a first fixing block 502 used in cooperation with the bolt 501, wherein the first fixing block 502 has a screw hole matching with the bolt 501, and the length of the first fixing block 502 (W in the figure)4Shown) is greater than the notch width of the mounting slot 305 but less than the in-slot width of the mounting slot 305. Will pressWhen the block is fixed with the second support 304 part of the water tank, the first fixing block 502 is firstly placed in the mounting groove 305 of the second support part 304, wherein the first fixing block 502 is placed along the direction of the width of the notch of the mounting groove 305, and because the length of the first fixing block 502 is greater than the width of the notch of the mounting groove 305, the first fixing block 502 cannot be pulled out from the notch of the mounting groove 305; then, the bolt 501 is screwed into the screw hole on the first fixing block 502 through the mounting hole at the bottom of the pressing block body and the notch of the mounting groove 305, and the pressing block and the water tank can be fixed after being screwed. It will be understood by those skilled in the art that the above-mentioned structure of the fastening member and the mounting groove is only a preferred embodiment, and in other embodiments, the fastening member and the mounting groove may be implemented by other structures, for example, the fastening member is a bolt, the mounting groove is a structure with threads and a size matched with the bolt, and the bolt is directly screwed into the mounting groove. For the sake of brevity, all possible configurations of the fasteners and mounting slots will not be described in detail herein.
Furthermore, the fastener includes, in addition to the bolt 501 and the first fixing block 502 shown in fig. 5, a second fixing block (not shown) used in cooperation with the bolt 501, where the second fixing block is provided with a screw hole matching with the bolt 501, and the length of the second fixing block is greater than the width of a gap between two adjacent photovoltaic modules.

Under this condition, the length of second fixed block needs to be greater than the width of the gap between the adjacent short frame of two adjacent photovoltaic module. Installing a pressing block between two adjacent short frames of two adjacent photovoltaic modules, specifically clamping a clamping groove structure of the pressing block on the wall of the water guide groove of the two adjacent short frames, respectively clinging two ends of a second fixing block to the bottom of the two adjacent short frames, and screwing a bolt into the second short frame through a mounting hole at the bottom of a pressing block bodyAnd in the screw holes of the fixing blocks, the fixing between the adjacent short frames of the two adjacent photovoltaic assemblies is realized until the fixing is realized. With respect to the compact shown in FIG. 2, due to the width of the bottom surface of the compact body (W in the drawing)1Expressed) is the distance between adjacent frames of two adjacent photovoltaic modules, so the length of the second fixed block only needs to be larger than the width of the bottom surface of the pressing block body. Referring to fig. 6 and 7, fig. 6 and 7 are schematic diagrams illustrating a longitudinal installation and a transverse installation of the photovoltaic module frame and the fixing device under the condition that the fastener includes a bolt, a first fixing block and a second fixing block.
