Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and more specifically, to a photovoltaic system and a lockable, width-adjustable briquetting module. Background Technology

[0002] Currently, the main process for installing and fixing photovoltaic (PV) modules is as follows: first, the PV modules are placed on the purlins, and then pressure blocks are set to fix the PV modules in place. However, during construction, because the PV modules are placed on the purlins beforehand, it is difficult for the gaps between the PV modules to be perfectly matched with the width of the pressure blocks. Specifically, there may be two situations: one is that the gaps between the PV modules are too small, causing the pressure blocks to not be able to be inserted, which usually requires adjusting the position of all PV modules, which is time-consuming and laborious; the other is that the gaps between the PV modules are too large, and the pressure blocks and PV modules cannot fit completely, causing the pressure blocks to easily break and loosen prematurely due to the reduced stress area. Regardless of which situation occurs, rework is usually required.

[0003] In conclusion, how to avoid the need for rework after the installation of photovoltaic modules is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The core of this application is to provide a lockable, adjustable-width clamping assembly, which avoids the need for rework after photovoltaic module installation. Another core aspect of this application is to provide a photovoltaic system including the aforementioned lockable, adjustable-width clamping assembly.

[0044] This application provides a lockable, width-adjustable pressure block assembly for use in photovoltaic systems and for pressing and fixing adjacent photovoltaic modules 7. The assembly includes a first adjusting block 11, a second adjusting block 12, and a tensioning assembly 2. The first side structure of the first adjusting block 11 is used to press against one of the adjacent photovoltaic modules 7, and the first side structure of the second adjusting block 12 is used to press against the other of the adjacent photovoltaic modules 7.

[0045] The second side structure of the first adjusting block 11 and the second side structure of the second adjusting block 12 are slidably engaged to form the pressure block 1, and the first adjusting block 11 and the second adjusting block 12 can move towards or away from each other along the width direction of the pressure block 1, and the second side structure of the first adjusting block 11 and the second side structure of the second adjusting block 12 are both used to be inserted into the gap between adjacent photovoltaic modules 7.

[0046] The tensioning assembly 2 is connected to the first adjusting block 11 and the second adjusting block 12, and is used to push the first adjusting block 11 and the second adjusting block 12 to move away from each other.

[0047] refer to Figure 1 , Figure 2 and Figure 3As explained, the first adjusting blocks 11 are arranged side by side, with the second side structure of the first adjusting block 11 and the second side structure of the second adjusting block 12 close to each other and slidably connected to form a complete pressure block 1. The sliding direction of the first adjusting block 11 and the second adjusting block 12 is the direction of the line connecting the first adjusting block 11 and the second adjusting block 12, or in other words, the sliding direction of the first adjusting block 11 and the second adjusting block 12 is the width direction of the pressure block 1. The first side structure of the first adjusting block 11 and the first side structure of the second adjusting block 12 are far apart and suspended. Correspondingly, a tensioning component 2 is provided between the first adjusting block 11 and the second adjusting block 12. The tensioning component 2 can apply a pushing force to the first adjusting block 11 and the second adjusting block 12, so that after they approach each other, they tend to move away from each other.

[0048] It should be noted that the type of tensioning component 2 is not limited, such as spring 21 or magnet of the same pole, as long as it can push the first adjusting block 11 and the second adjusting block 12 away from each other.

[0049] In use, the first adjusting block 11 and the second adjusting block 12 are squeezed together to move them closer together, which reduces the width of the second side structure connecting the first adjusting block 11 and the second adjusting block 12. This allows it to be placed into the gap between adjacent photovoltaic modules 7. After the pressing block 1 is placed in place, the first side structure of the first adjusting block 11 and the first side structure of the second adjusting block 12 are pressed onto the top of the side structure of the adjacent photovoltaic module 7. Under the tensioning force of the tensioning component 2, the first adjusting block 11 and the second adjusting block 12 are pushed away from each other, so that the second side structure connecting the first adjusting block 11 and the second adjusting block 12 can fit against the side of the adjacent photovoltaic module 7. This ensures the reliability of the photovoltaic module 7 installation and avoids rework after the photovoltaic module 7 is installed.

[0050] Based on the above embodiments, a fastener 3 is also included; both the first adjusting block 11 and the second adjusting block 12 have elongated adjusting holes 1011, and the adjusting holes 1011 of the first adjusting block 11 and the second adjusting block 12 extend along the sliding direction of the first adjusting block 11 and the second adjusting block 12.

[0051] The fastener 3 passes through the adjustment hole 1011 of the first adjustment block 11 and the adjustment hole 1011 of the second adjustment block 12, and the fastener 3 can move along the length direction of the adjustment hole 1011.

[0052] refer to Figure 1 , Figure 2 and Figure 3As explained, the projections of the second side structure of the first adjusting block 11 and the second side structure of the second adjusting block 12 along the height direction of the pressure block 1 coincide with each other. Through holes are provided in the second side structures of the first adjusting block 11 and the second side structure of the second adjusting block 12 as adjusting holes 1011, so that the fastener 3 can pass through the adjusting holes 1011 of the first adjusting block 11 and the second adjusting block 12. The size of the adjusting hole 1011 along the sliding direction of the first adjusting block 11 and the second adjusting block 12 is larger than the diameter of the fastener 3, so that the fastener 3 can move in the adjusting hole 1011 along the sliding direction of the first adjusting block 11 and the second adjusting block 12. The fastener 3 can be used to fix the locking width adjustable pressure block assembly, while meeting the movement requirements of the first adjusting block 11 and the second adjusting block 12.

[0053] It should be noted that the type of adjustment hole 1011 is not limited, as long as it can meet the movement requirements of the first adjustment block 11 and the second adjustment block 12. The adjustment hole 1011 can be a round hole or a square hole with a diameter greater than or equal to the movement stroke of the first adjustment block 11 and the second adjustment block 12. Preferably, the adjustment hole 1011 is an elongated hole, and the fastener 3 is slidably fitted in the adjustment hole 1011 so as to realize the sliding fit between the first adjustment block 11 and the second adjustment block 12.

[0054] refer to Figures 1 to 5 As explained above, based on the above embodiments, both the first adjusting block 11 and the second adjusting block 12 are made of profiles, and the cross-sectional shape of the first adjusting block 11 and the second adjusting block 12 is Z-shaped. In other words, the first adjusting block 11 and the second adjusting block 12 are composed of three plates that are spliced ​​and fixedly connected by side, namely, the pressing plate 103, the connecting plate 102 and the sliding plate 101 are connected in sequence, and the pressing plate 103 is parallel to the sliding plate 101, and both the pressing plate 103 and the sliding plate 101 are perpendicular to the connecting plate 102. Thus, after the first adjusting block 11 and the second adjusting block 12 are connected by their respective connecting plates 102, a complete pressing block 1 with a convex shape is formed. The pressing plate 103 is the first side structure of the above-mentioned adjusting block, and the connecting plate 102 and the sliding plate 101 together form the second side structure of the above-mentioned adjusting block, which is used to insert into the gap between adjacent photovoltaic modules 7. With this setting, the production difficulty and weight of the pressing block 1 are both low, which helps to reduce the installation cost of photovoltaic modules 7.

[0055] The structural types of the first adjusting block 11 and the second adjusting block 12 are illustrated using the structure of the first adjusting block 11 as an example. Please refer to [link / reference needed]. Figure 4 and Figure 5The left side of the sliding plate 101 is connected to the lower side of the connecting plate 102, while the right side of the sliding plate 101, which is not connected and is away from the connecting plate 102, has a sliding part 1012. A guide rail 1021 is provided at the corner where the connecting plate 102 intersects and connects with the sliding plate 101. Furthermore, to meet the requirement that the first adjusting block 11 and the second adjusting block 12 slide through the cooperation of the sliding part 1012 and the guide rail 1021, the guide rail 1021 of the first adjusting block 11 is located on the side of the sliding plate 101 of the first adjusting block 11 and is located close to the second adjusting block 12. On one side of the pressing plate 103, the guide rail 1021 of the second adjusting block 12 is located on the side of the sliding plate 101 of the second adjusting block 12 and is located close to the pressing plate 103 of the second adjusting block 12. Thus, the sliding plate 101 of the first adjusting block 11 and the sliding plate 101 of the second adjusting block 12 can be arranged parallel to each other, and the sliding part 1012 of the first adjusting block 11 and the guide rail 1021 of the second adjusting block 12, as well as the sliding part 1012 of the second adjusting block 12 and the guide rail 1021 of the first adjusting block 11, can slide and engage along the width direction of the pressing block 1.

[0056] refer to Figures 1 to 3 As can be seen, the lower right sliding part 1012 of the left first adjusting block 11 can be inserted into the guide rail 1021 of the right second adjusting block 12 in a lateral direction, and the lower left sliding part 1012 of the right second adjusting block 12 can be inserted into the guide rail 1021 of the left first adjusting block 11 in a lateral direction.

[0057] It should be noted that the types of sliding parts 1012 and guide rails 1021 are not limited, as long as the requirement of sliding cooperation between the first adjusting block 11 and the second adjusting block 12 is met. For example, the sliding part 1012 can be a slider, and several sliders are machined and formed on the free side of the sliding plate 101 and arranged along the length direction of the pressure block 1. The guide rail 1021 can be a channel extending along the width direction of the pressure block 1, and several channels are machined and formed on the connecting plate 102 and arranged along the length direction of the pressure block 1. Several sliding parts 1012 are slidably inserted into the corresponding guide rails 1021. After the first adjusting block 11 and the second adjusting block 12 are assembled.

[0058] Based on the above embodiments, the free sides of the sliding plates 101 of the first adjusting block 11 and the second adjusting block 12 are provided with positioning grooves 1013, and the connecting plates 102 of the first adjusting block 11 and the second adjusting block 12 are provided with positioning parts 1022 at the corners where they connect to the sliding plates 101.

[0059] The positioning part 1022 of the first adjusting block 11 is inserted into the positioning groove 1013 of the second adjusting block 12, and the positioning part 1022 of the second adjusting block 12 is inserted into the positioning groove 1013 of the first adjusting block 11. The positioning part 1022 can move along the width direction of the pressure block 1 in the corresponding positioning groove 1013 to limit the relative movement stroke of the first adjusting block 11 and the second adjusting block 12.

[0060] Furthermore, the guide rail 1021 and positioning groove 1013 of the first adjusting block 11 and the second adjusting block 12 are through grooves formed by their own pultrusion molding. The sliding part 1012 and positioning part 1022 of the first adjusting block 11 and the second adjusting block 12 are long strip plate structures formed by their own pultrusion molding. The opening of the guide rail 1021 is located on the side of the sliding plate 101 along the height direction of the pressure block 1, and the positioning part 1022 surrounds the opening of the guide rail 1021.

[0061] Similarly, the structure of the sliding part 1012 and the guide rail 1021 is illustrated using the first adjusting block 11 as an example. Please refer to [link / reference needed]. Figure 4 and Figure 5 A positioning groove 1013 is provided on the right side of the sliding plate 101 where it is not connected and is away from the connecting plate 102, while a positioning part 1022 is provided at the corner where the connecting plate 102 intersects and connects with the sliding plate 101; furthermore, in order to limit the stroke of the relative movement of the first adjusting block 11 and the second adjusting block 12, a reference is made. Figures 1 to 3 As explained, when the sliding plate 101 of the first adjusting block 11 and the sliding plate 101 of the second adjusting block 12 are arranged parallel to each other, the positioning part 1022 of the first adjusting block 11 is inserted into the positioning groove 1013 of the second adjusting block 12, and the positioning part 1022 of the second adjusting block 12 is inserted into the positioning groove 1013 of the first adjusting block 11. The movement of the positioning part 1022 can be restricted by the two side walls of the positioning groove 1013 along the width direction of the pressure block 1, so that the first adjusting block 11 and the second adjusting block 12 can move to the extreme positions at both ends of the stroke. With this arrangement, the first adjusting block 11 and the second adjusting block 12 achieve sliding cooperation through the guide rail 1021 and the sliding part 1012, and the positioning part 1022 and the positioning groove 1013, so the relative movement stability of the first adjusting block 11 and the second adjusting block 12 is high.

[0062] To reduce production difficulty, such as Figure 4 and Figure 5As shown, both the first adjusting block 11 and the second adjusting block 12 are made of pultruded profiles. The guide rail 1021, sliding part 1012, positioning groove 1013 and positioning part 1022 are all structures formed by the extrusion molding process of the first adjusting block 11 and the second adjusting block 12. The positioning part 1022 surrounds the opening of the guide rail 1021, so that the opening of the cavity is located on the lower or upper side of the sliding plate 101, for the sliding part 1012 to be inserted into the guide rail 1021. During the movement of the sliding part 1012 along the width direction of the pressure block 1, the movement of the sliding part 1012 can also be restricted by the positioning part 1022 and the side wall opposite to the positioning part 1022 and surrounding the guide rail 1021, so that the first adjusting block 11 and the second adjusting block 12 can move to the extreme positions at both ends of the stroke. With this configuration, the structure of the first adjusting block 11 and the second adjusting block 12 is simple and compact.

[0063] For further information, please refer to [link / reference]. Figure 4 and Figure 5 The connecting plate 102 of the first adjusting block 11 and the second adjusting block 12 has a weight reduction hole 1024 at the corner where it connects to the sliding plate 101. The weight reduction hole 1024 is a through hole formed during the extrusion molding process of the first adjusting block 11 and the second adjusting block 12. The weight reduction hole 1024 of the first adjusting block and the guide rail 1021, and the weight reduction hole 1024 of the second adjusting block and the guide rail 1021 are arranged side by side along the height direction of the pressure block 1 to reduce weight and cost.

[0064] Based on the above embodiments, the tensioning assembly 2 includes a spring 21; the connecting plate 102 of the first adjusting block 11 and the connecting plate 102 of the second adjusting block 12 each have a positioning pin 1023 on opposite sides;

[0065] The two ends of the spring 21 are sleeved on the outside of the positioning pin 1023 of the first adjusting block 11 and the positioning pin 1023 of the second adjusting block 12.

[0066] refer to Figures 1 to 3 As explained, the first adjusting block 11 and the second adjusting block 12 are elastically connected by a spring 21 extending along the width direction of the aforementioned pressure block 1. For the installation of the spring 21, refer to... Figure 4 and Figure 5 As explained, a positioning pin 1023 is machined on the connecting plate 102 of the first adjusting block 11 and the second adjusting block 12. The positioning pin 1023 extends along the width direction of the pressure block 1, and the positioning pin 1023 is located on the side of the connecting plate 102 away from the pressing plate 103. Thus, when the pressing plates 103 of the first adjusting block 11 and the second adjusting block 12 are arranged side by side and far apart to form a convex-shaped pressure block 1, such as Figure 2As shown, the positioning pin 1023 of the first adjusting block 11 and the positioning pin 1023 of the second adjusting block 12 are arranged opposite to each other, and the two ends of the spring 21 are respectively sleeved on the outside of the positioning pin 1023 of the first adjusting block 11 and the outside of the positioning pin 1023 of the second adjusting block 12.

[0067] Based on the above embodiment, there is an installation space between the sliding plate 101 of the first adjusting block 11 and the sliding plate 101 of the second adjusting block 12. The positioning pin 1023 is provided on the part of the plate body that forms the installation space around the connecting plate 102 of the first adjusting block 11 and the second adjusting block 12. The spring 21 is slidably inserted into the installation space.

[0068] refer to Figure 1 and Figure 2 As explained, the sliding plate 101 of the first adjusting block 11 and the sliding plate 101 of the second adjusting block 12 are arranged opposite to each other, with an installation space between them. The positioning pins 1023 of the first adjusting block 11 and the second positioning pins 1023 are located on both sides of the installation space along the width direction of the aforementioned pressure block 1, so that the spring 21 can be installed in the installation space. With this arrangement, the structure of the locking width adjustable pressure block assembly is compact, and it is beneficial to improve the stability of the first adjusting block 11 and the second adjusting block 12 moving away from each other under the push of the tensioning assembly 2.

[0069] Based on the above embodiment, the number of springs 21 is at least two, the number of positioning pins 1023 of the first adjusting block 11 and the number of positioning pins 1023 of the second adjusting block 12 are both at least two, a plurality of springs 21 and a plurality of positioning pins 1023 are arranged along the length direction of the pressure block 1, and the two ends of the springs 21 are sleeved on the outside of the corresponding positioning pins 1023.

[0070] refer to Figure 3 As explained, the locking width adjustable pressure block assembly is equipped with several springs 21, and each spring 21 is arranged along the length direction of the pressure block 1. To meet the installation requirements, the number of positioning pins 1023 of the first adjusting block 11 and the number of positioning pins 1023 of the second adjusting block 12 are both equal to the number of springs 21 in the tensioning assembly 2. Each spring 21 corresponds one-to-one with the positioning pins 1023 of the first adjusting block 11 and the second adjusting block 12, so that each spring 21 can be fitted onto the corresponding positioning pins 1023 of the first adjusting block 11 and the corresponding positioning pins 1023 of the second adjusting block 12.

[0071] Based on the above embodiment, it also includes a spring pad 4 and a flat pad 5. Both the spring pad 4 and the flat pad 5 are sleeved on the outer periphery of the fastener 3 and sandwiched between the tail end of the fastener 3 and the pressure block 1, and the flat pad 5 can contact the pressure block 1.

[0072] refer to Figures 1 to 3As explained, a spring washer 4 and a flat washer 5 are fitted around the outer periphery of the fastener 3. The flat washer 5 directly contacts the pressure block 1 to increase the contact area between the fastener 3 and the pressure block 1. The spring washer 4 is sandwiched between the tail end of the fastener 3 and the flat washer 5 to generate elastic force between the fastener 3 and the pressure block 1, thereby increasing the friction between the fastener 3 and the pressure block 1 and preventing the fastener 3 from loosening.

[0073] Based on the above embodiments, a fixing pad 6 is also included. The fixing pad 6 is used to be inserted into the cavity of the photovoltaic purlin 8. The fixing pad 6 has a threaded hole, and the head end of the fastener 3 is inserted into and threaded into the threaded hole.
