Description

Technical Field

[0001] The present invention relates to photovoltaic power station support equipment, and in particular to a pressing block suitable for orderly installation of photovoltaic components and an installation method. Background Art

[0002] Photovoltaic power generation is one of the new energy industries. To keep up with the development of new energy and energy conservation and emission reduction, most factories and industrial parks have chosen to build rooftop photovoltaic power stations.

[0003] In order to maximize the utilization rate of the roof area, most rooftop photovoltaic power stations adopt the design of fully covering the roof with photovoltaic modules. However, the conventional installation process requires the photovoltaic modules on both sides of the module to be placed before the module can be installed. However, due to the large area of the photovoltaic modules themselves, the installation distance is too large. The installers cannot complete the installation without stepping on the photovoltaic brackets or using other equipment for assistance. This also means that when using the conventional installation process to install photovoltaic modules, a certain amount of space must be reserved at the edge for the installers to install the modules, which limits the maximization of the installed capacity of the rooftop power station. At the same time, it is inevitable that the installers will step on the module frame to install, which easily causes the risk of hidden cracks and damage to the module cells due to stepping. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, one of the purposes of the present invention is to provide a pressing block suitable for the orderly installation of photovoltaic modules, which can solve the problem that when the roof is fully covered with photovoltaic modules, the installation of the pressing code for fixing the modules is difficult, and the module cell is prone to hidden cracks and damage due to stepping on the installation.

[0005] The second purpose of the present invention is to provide an installation method for a pressing block suitable for the orderly installation of photovoltaic modules, which can solve the problem that when the roof is fully covered with photovoltaic modules, the installation of the pressing code for fixing the modules is difficult, and the module battery cells are prone to hidden cracks and damage due to stepping on the installation.

[0006] In order to achieve one of the above purposes, the technical solution adopted by the present invention is as follows:

[0007] A pressing block suitable for orderly installation of photovoltaic components comprises a base plate, a first vertical plate, a second vertical plate, a first pressing plate, a second pressing plate, a first pressing foot and a second pressing foot, wherein the lower end of the first vertical plate and the upper end of the first pressing foot are both connected to one end of the base plate, the lower end of the second vertical plate and the upper end of the second pressing foot are both connected to the other end of the base plate, one end of the first pressing plate is connected to the upper end of the first vertical plate, and one end of the second pressing plate is connected to the upper end of the second vertical plate, a bolt hole is provided on the base plate, a clamping portion is provided on the lower end surface of the first pressing plate, a rotating portion is provided on the lower end surface of the second pressing plate, and a side end surface of the second vertical plate close to the second pressing plate is recessed in a direction away from the second pressing plate to form a rotating groove.

[0008] Preferably, the length of the first presser foot is smaller than the length of the second presser foot.

[0009] Preferably, the distance between the lower end of the rotating portion and the lower end of the second pressure foot is equal to the height of the photovoltaic module frame.

[0010] Preferably, the pressing portion includes a plurality of protruding teeth that are snap-connected to the photovoltaic module frame, and the end of the first pressing plate extends outward to form an extension portion that is snap-connected to the photovoltaic module frame.

[0011] Preferably, the inner diameter of the rotating part is arranged to increase from bottom to top.

[0012] Preferably, the bottom plate, the first vertical plate, the second vertical plate, the first pressing plate, the second pressing plate, the first pressing foot, the second pressing foot, the pressing portion and the rotating portion are integrally formed.

[0013] In order to achieve the second of the above objectives, the technical solutions adopted by the present invention are as follows:

[0014] A method for installing a pressing block suitable for orderly installation of photovoltaic modules as described above comprises the following steps:

[0015] S1: Insert the bolt holes of the bottom plate into the bolts connected to the guide rails, tighten the nuts on the bolts, drive the pressing portion of the first pressing plate to snap-connect with the upper end surface of the frame of the first photovoltaic module, and make the first vertical plate and the first pressure foot tightly contact with the side edge of the frame of the first photovoltaic module;

[0016] S2: Insert the second photovoltaic module in an inclined manner, drive the upper end of the second photovoltaic module frame into the rotation groove, and rotate the second photovoltaic module with the rotating part as the fulcrum so that the upper end surface of the second photovoltaic module frame abuts the rotating part and the second pressure foot is in close contact with the side of the second photovoltaic module frame;

[0017] S3: Determine whether the photovoltaic modules in the same array are installed. If so, end the process. If not, execute S1.

[0018] Preferably, conventional edge pressure codes are used to fix the outer edges of the photovoltaic modules at the beginning and end of the array.

[0019] Compared with the existing technology, the beneficial effect of the present invention is that: through the connection of the first pressing plate with the base plate and the guide rail, the first photovoltaic component close to one end of the base plate is directly fixed, and then the second photovoltaic component is obliquely inserted into the area surrounded by the second pressing plate, the second vertical plate and the second pressure foot, and then the second photovoltaic component is rotated with the rotating part as the fulcrum, so that the second photovoltaic component is installed at the other end of the base plate, that is, it is stuck in the area surrounded by the second pressing plate, the second vertical plate and the second pressure foot, so as to realize the orderly installation of the photovoltaic components along the installation sequence, and there is no need to place both photovoltaic components and then use the peripheral area or step on the photovoltaic components to connect the pressing block and the guide rail, that is, the installation method of "pre-tightening the pressing code and then placing the photovoltaic component" is adopted to distinguish it from the traditional installation method of "placing the photovoltaic component first and then pre-tightening the pressing code", optimizes the installation process of the pressing block in the conventional installation process, avoids the risk of hidden cracks in the photovoltaic component caused by irregular operations such as stepping on the component due to excessive installation distance, and improves the installation efficiency of the photovoltaic component.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0030] In the present invention, the photovoltaic module is preferably a conventional photovoltaic module with a frame, and the guide rail can be a guide rail in a conventional photovoltaic bracket device. The pressure block is connected to the clamp through the guide rail, and the clamp is connected to the roof. Preferably, the groove of the guide rail is adapted to the head of the bolt (hexagonal bolt), and the head of the bolt can be directly clamped in the groove. Furthermore, the groove of the guide rail is provided with a necking structure, which can further prevent the bolt from slipping out of the groove of the guide rail. Alternatively, the guide rail is shaped like the corner-type color steel tile integrated aluminum profile clamp for fixing photovoltaic modules disclosed in Chinese patent CN216949132U; wherein the first photovoltaic module and the second photovoltaic module are photovoltaic modules arranged in sequence in front and back along the installation order.

[0031] Example 1:

[0032] like Figure 1-4As shown, in this embodiment, a pressing block suitable for orderly installation of photovoltaic modules includes a base plate 1, a first vertical plate 2, a second vertical plate 3, a first pressing plate 4, a second pressing plate 5, a first pressure foot 6 and a second pressure foot 7. The lower end of the first vertical plate 2 and the upper end of the first pressure foot 6 are both connected to one end of the base plate 1, the lower end of the second vertical plate 3 and the upper end of the second pressure foot 7 are both connected to the other end of the base plate 1, one end of the first pressing plate 4 is connected to the upper end of the first vertical plate 2, and one end of the second pressing plate 5 is connected to the upper end of the second vertical plate 3. Bolt holes are provided on the base plate 1, the lower end surface of the first pressing plate 4 is provided with a clamping portion 41, and the lower end surface of the second pressing plate 5 is provided with a rotating portion 51. The end surface of the second vertical plate 3 on one side close to the second pressing plate 5 is recessed toward the direction away from the second pressing plate 5 to form a rotating groove 52. Preferably, the bottom plate 1, the first vertical plate 2, the second vertical plate 3, the first pressing plate 4, the second pressing plate 5, the first presser foot 6, the second presser foot 7, the pressing portion 41 and the rotating portion 51 are integrally formed profiles. Preferably, the length of the first presser foot 6 is smaller than the length of the second presser foot 7. In this embodiment, the bolts are pre-inserted into the guide rails, and the first photovoltaic assembly is placed on one side. The bottom plate 1 is then connected to the rod of the bolt through its bolt hole, so that the first pressing plate 4 is pressed against the upper end face of the frame of the first photovoltaic assembly. Preferably, the pressing portion 41 includes a number of convex teeth that are snap-connected to the frame of the first photovoltaic assembly. The end of the first pressing plate 4 extends outward to form an extension portion 42 that is snap-connected to the frame of the first photovoltaic assembly. In this embodiment, the convex teeth are matched with the grooves on the frame of the first photovoltaic assembly, and the curvature of the extension portion 42 is the same as that of the first photovoltaic assembly. The curvature of the photovoltaic component frame is the same. Tighten the nut on the bolt so that the convex teeth are snap-connected with the groove on the first photovoltaic component frame, and the extension part 42 fits with the first photovoltaic component frame, so that the convex teeth and the extension part 42 of the first pressure plate 4 can form a better fixation with the photovoltaic component, and the first pressure foot 6 and the first vertical plate 2 are in contact with the side of the frame of the first photovoltaic component, and the two planes are opposite to each other, forming a face-to-face combination, so the reliability of the installation is greatly improved, thereby eliminating the domino collapse of the photovoltaic array due to the loosening of a certain fixed point in the system. Furthermore, the distance between the lower end of the rotating part 51 and the lower end of the second pressure foot 7 is equal to the height of the photovoltaic module frame. When the nut on the bolt is tightened, the first pressure plate 4 presses the first photovoltaic module frame at the same time. At this time, the lower end of the second pressure foot 7 just abuts against the guide rail below, avoiding the pressure block from tilting when the nut on the bolt is tightened, ensuring that there is enough installation space for the second photovoltaic module, and then the second photovoltaic module is obliquely inserted into the second pressure plate 5 and the second pressure foot 7, and the second photovoltaic module is rotated with the rotating part 51 as the fulcrum, so that the second photovoltaic module is installed at the other end of the base plate 1.In this embodiment, the inner diameter of the rotating part 51 is set to increase from bottom to top, that is, the rotating part 51 is a structure that is wide at the top and narrow at the bottom (conical, hemispherical, prismatic, etc.), so that the second photovoltaic component can be inserted into the area surrounded by the second pressure plate 5, the second vertical plate 3 and the second pressure foot 7, and the side end surface of the second vertical plate 3 close to the second pressure plate 5 is recessed in the direction away from the second pressure plate 5 to form a rotation groove 52. When the second photovoltaic component rotates, the rotation groove 52 provides a larger rotation area to avoid the frame of the second photovoltaic component from interfering with the second vertical plate 3 during rotation.

[0033] Example 2:

[0034] like Figure 1-4 As shown, a method for installing a pressing block for orderly installing photovoltaic modules as described in the first embodiment above includes the following steps:

[0035] In this embodiment, conventional pressing blocks or pressing blocks suitable for orderly installation of photovoltaic modules are used in advance to fix the frames of the photovoltaic modules in the current array that are closest to the roof edge.

[0036] S1: Insert the bolt holes of the bottom plate 1 into the bolts connected to the guide rails, tighten the nuts on the bolts, drive the pressing portion 41 of the first pressing plate 4 to snap-connect with the upper end surface of the frame of the first photovoltaic module, and make the first vertical plate 2 and the first pressure foot 6 tightly fit with the side edge of the frame of the first photovoltaic module;

[0037] Specifically, the head of the bolt used to connect the base plate 1 is pre-inserted into the guide rail, and then the bolt hole of the base plate 1 is passed through the bolt, and the nut on the bolt is tightened so that the first pressure plate 4 is pressed on the frame of the first photovoltaic component (if the current first photovoltaic component is the photovoltaic component closest to the roof edge in the current array, then the side frame is the side frame of the first photovoltaic component away from the roof edge), wherein the convex teeth on the clamping part 41 of the first pressure plate 4 are snap-connected with the groove on the frame of the first photovoltaic component, and the extension part 42 is fitted with the frame of the first photovoltaic component, so that the first pressure plate 4 can form a better fixed connection with the photovoltaic component, and at the same time, the first pressure foot 6 and the first vertical plate 2 are in contact with the side edge of the frame of the first photovoltaic component, and the two planes are opposite to form a face-to-face combination, so that the reliability of the installation is greatly improved, thereby eliminating the domino collapse of the photovoltaic array due to the loosening of a certain fixed point in the system.

[0038] S2: Insert the second photovoltaic module in an inclined manner, drive the upper end of the second photovoltaic module frame into the rotation groove 52, and rotate the second photovoltaic module with the rotating part 51 as the fulcrum, so that the upper end surface of the second photovoltaic module frame abuts against the rotating part 51, and the second pressure foot 7 is in close contact with the side edge of the second photovoltaic module frame;

[0039] Specifically, after tightening the nuts on the bolts, start installing the second photovoltaic module that is arranged after the first photovoltaic module in the installation order, and insert the second photovoltaic module into the area surrounded by the second pressing plate 5, the second vertical plate 3 and the second presser foot 7 in an inclined manner. At this time, the frame of the second photovoltaic module abuts against the rotating portion 51 of the lower end surface of the second pressing plate 5 (as shown in FIG. Figure 2 As shown), the rotating portion 51 is then used as a fulcrum, and the end of the second photovoltaic component away from the pressing block is rotated downward, wherein the end surface of the second vertical plate 3 close to the second pressing plate 5 is recessed in the direction away from the second pressing plate 5 to form a rotation groove 52. When the second photovoltaic component rotates, the rotation groove 52 provides a larger rotation area to prevent the frame of the second photovoltaic component from interfering with the second vertical plate 3 during the rotation process, driving the second photovoltaic component to be stuck in the area surrounded by the second pressing plate 5, the second vertical plate 3 and the second pressure foot 7 (as shown). Figure 3 As shown), the second pressure foot 7 abuts against the side of the frame of the first photovoltaic component, and the two planes are opposite to each other, forming a face-to-face combination, so the reliability of the installation is greatly improved, and the domino collapse of the photovoltaic array caused by the loosening of a certain fixed point in the system is eliminated, thereby realizing the orderly installation of photovoltaic components along the installation sequence, optimizing the installation process of the pressure block in the conventional installation process, and avoiding the risk of hidden cracks in the photovoltaic components due to irregular operations such as stepping on the components due to excessive installation distance.

[0040] S3: Determine whether the photovoltaic modules in the same array are installed. If so, end the process. If not, execute S1.

[0041] Specifically, after the second photovoltaic component is installed, it is determined whether all the photovoltaic components in the same array have been installed. If so, a conventional pressure block is used to fix the other side frame of the second photovoltaic component, or a pressure block suitable for orderly installation of photovoltaic components is provided with a side of the first pressure plate 4 to fix the other side frame of the second photovoltaic component; if not, return to S1, at this time the second photovoltaic component is equivalent to the first photovoltaic component in S1, and the other side frame of the second photovoltaic component is fixed using a pressure block suitable for orderly installation of photovoltaic components with a side of the first pressure plate 4, and then continue to execute S2, and so on, until the installation of the photovoltaic components in the same array is completed; preferably, a conventional edge pressure code is used to fix the outer edges of the photovoltaic components located at the first and last ends of the array, and specifically, a conventional edge pressure code is used to fix the outer edges of the first and last photovoltaic components located in the array (such as Figure 4 As shown), the photovoltaic modules at the end of the array can be better combined with the mounting bracket and the roof under the compaction of the conventional edge pressure code, thereby improving various performances and ensuring that the entire array is better combined with the mounting bracket and the roof.
