Description

Technical Field

[0001] This utility model relates to a novel purlin and photovoltaic module installation mechanism, belonging to the field of photovoltaic equipment technology. Background Technology

[0002] Photovoltaic power generation is a technology that uses solar panels to convert solar energy into electrical energy. A photovoltaic tracking bracket is a power device that can adjust the tilt angle of solar panels in real time, ensuring they are always aligned with the sun. The application of photovoltaic tracking brackets can effectively increase the amount of solar radiation received by the photovoltaic array, thereby increasing the overall power generation of the photovoltaic power generation system.

[0003] In existing technologies, purlins are typically installed on the main beam to connect the photovoltaic modules and fix them to the main beam. The purlins in existing technologies are usually open-type inverted V-shaped and fixed to the main beam with bolts. The overall strength of such purlins is low, and because the opening faces upward, the parts on both sides that support the profiles are prone to deformation, causing local buckling and damage to the bottom surface of the profiles. Furthermore, since the part supporting the profiles is a single-layer structure, additional shims are required to increase local strength, making installation difficult.

[0004] To address the aforementioned issues, this application proposes a novel purlin and photovoltaic module installation mechanism. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new type of purlin and photovoltaic module installation mechanism. By using a rectangular tube with a closed structure in conjunction with module mounting parts to fix and install the photovoltaic module, the structural strength and wind resistance performance are effectively improved, which can effectively solve the problems in the background technology.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A novel purlin and photovoltaic module installation mechanism for installing photovoltaic modules includes a rectangular tube and module mounting components. The rectangular tube has at least two sets of first mounting holes for mounting the module mounting components. The module mounting components include a flat plate portion and a bent portion. The bent portion is arranged perpendicular to the flat plate portion and is arranged in 1-2 portions. The module mounting components are fixedly connected to the rectangular tube by first fasteners. The module mounting components have second mounting holes for mounting photovoltaic modules on the left and right sides of the rectangular tube.

[0008] As a further improvement of this utility model, the component mounting part is composed of a flat plate part and a bent part, and the cross-section of the component mounting part is L-shaped.

[0009] As a further improvement of this utility model, the component mounting part is composed of a flat plate portion and two bent portions symmetrically arranged relative to the flat plate portion, and the cross-section of the component mounting part is arranged in an inverted U-shape.

[0010] As a further improvement of this utility model, the first mounting hole is configured as an L-shaped through hole that matches the component mounting part.

[0011] As a further improvement of this utility model, the first mounting hole is set as an inverted U-shaped hole that matches the component mounting hole, or the first mounting hole is set as a rectangular through hole.

[0012] As a further improvement of this utility model, the rectangular tube and the component mounting part are each provided with a first circular through hole that matches the first fastener.

[0013] As a further improvement of this utility model, a first circular through hole is provided on the flat plate and near one of the bends.

[0014] As a further improvement of this utility model, the first fastener is configured as a T-bolt.

[0015] As a further improvement of this utility model, the component mounting part is integrally formed by bending.

[0016] A photovoltaic module installation mechanism includes the aforementioned novel purlin, as well as U-bolts and a main beam, wherein the U-bolts pass through a rectangular tube to fix the purlin to the top of the main beam.

[0017] The beneficial effects of this utility model are as follows: A novel purlin and photovoltaic module installation mechanism is provided. By using a rectangular tube in conjunction with a module mounting component to form a novel purlin, compared with the existing purlins with a Z-shaped opening, the rectangular tube with a closed structure as the main support has better load-bearing capacity and wind resistance. At the same time, the module mounting component is installed with a structure protruding from the rectangular tube, forming an L-shaped stepped space above the module mounting component, which facilitates the support of the photovoltaic module during installation. In addition, the part of the rectangular tube above the module mounting component can be used to position the photovoltaic module during installation. By using a T-bolt as the first fastener, when the nut is installed with a power tool, the bent part will form a limit with the T-bolt head, preventing the T-bolt from rotating on the rectangular tube, thereby avoiding slippage during the tightening of the nut, making the installation process more convenient and faster.

[0028] Example

[0029] like Figures 1-6 As shown, a novel purlin for installing photovoltaic modules is disclosed to solve the problems of low strength and inconvenient installation of open-type zigzag purlins in the prior art. The novel purlin consists of a rectangular tube 1, a module mounting component 2, and a first fastener 3. At least two sets of first mounting holes 11 for installing the module mounting component 2 are provided on the rectangular tube 1. More first mounting holes 11 and module mounting components 2 can be set according to the size of the photovoltaic module. The module mounting component 2 passes through the first mounting holes 11 and is fixedly installed on the rectangular tube 1 by the first fastener 3. The module mounting component 2 consists of a flat plate part 22 and a bent part 23 formed by bending. The bent part 23 is formed by bending vertically downward along the length direction of the flat plate part 22. The number of bent parts 23 is set to one or two. Second mounting holes 5 for installing photovoltaic modules are provided on the flat plate part 22 at the left and right sides of the rectangular tube 1. The flat plate part 22 is used to support the installation of photovoltaic modules, and the bent part 23 is used to strengthen the structural strength of the module mounting component 2.

[0030] A new type of purlin is formed by using a rectangular tube 1 in conjunction with a component mounting piece 2. Compared with the existing purlins with a zigzag opening, the rectangular tube 1 with a closed structure is used as the main support, resulting in better load-bearing capacity and wind resistance. At the same time, the component mounting piece 2 is installed with a structure that protrudes from the rectangular tube 1, forming an L-shaped stepped space above the component mounting piece 2, which facilitates the support of photovoltaic modules during installation. In addition, the part of the rectangular tube 1 above the component mounting piece 2 can be positioned during the installation of photovoltaic modules. The component mounting piece 2, which is composed of an integrally formed flat plate part 22 and a bent part 23, has higher structural strength than the flat plate structure used for installing photovoltaic modules with open purlins.

[0031] In some alternative embodiments, such as Figure 3 and Figure 6As shown, the component mounting part 2 consists of a flat plate part 22 and a bent part 23, and the cross-section of the component mounting part 2 is L-shaped.

[0032] More specifically, the first mounting hole 11 is configured as an L-shaped through hole that matches the component mounting piece 2.

[0033] By installing the L-shaped component mounting part 2 into the L-shaped first mounting hole 11, the upper or lower surface of the component mounting part 2 contacts the inner wall of the first mounting hole 11 along the length direction of the component mounting part 2, forming a stable support between the component mounting part 2 and the rectangular tube 1, effectively increasing the structural strength without increasing the cost.

[0034] In some alternative embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the component mounting part 2 consists of a flat plate part 22 and two bent parts 23 arranged symmetrically with respect to the flat plate part 22. The cross-section of the component mounting part 2 is arranged in an inverted U-shape.

[0035] More specifically, the first mounting hole 11 is configured as an inverted U-shaped hole that matches the component mounting hole.

[0036] Similarly, the component mounting part 2, which adopts a symmetrical inverted U-shaped structure, has a more uniform stress distribution and higher structural strength.

[0037] Or, as Figure 5 As shown, the first mounting hole 11 is set as a rectangular through hole. Considering the processing problem of the inverted U-shaped hole, since the thickness of the component mounting part 2 is generally not too thick, the commonly used processing method is laser cutting, which is costly. The inverted U-shaped hole can be replaced with a rectangular through hole with lower processing cost.

[0038] In some alternative embodiments, both the rectangular tube 1 and the component mounting part 2 are provided with a first circular through hole 221 that matches the first fastener 3. Correspondingly, a second circular through hole 12 for installing the first fastener 3 is provided on the top of the rectangular tube 1.

[0039] Furthermore, a first circular through-hole 221 is provided on the flat plate portion 22 and near one of the bends 23. For example, for a component mounting member 2 provided with a bend 23, the first circular through-hole 221 is arranged in such a way as... Figure 6 As shown, near the bend 23, for the component mounting part 2 with two bends 23, the first circular through hole 221 is arranged as follows: Figure 4 , Figure 5 The position shown is near one of the bends 23.

[0040] As a preferred option, such as Figures 4-6As shown, the first fastener 3 is set as a T-bolt 31. Considering the convenience of actual installation, the T-bolt 31 is selected as the first fastener 3. During installation, the T-shaped head of the T-bolt 31 is placed inside the rectangular tube 1, and the screw part extends out of the rectangular tube 1 through the first circular through hole 221 and the second circular through hole 12 in sequence. The screw is fixedly installed by connecting the nut to the screw part of the T-bolt 31 through the nut thread. When the nut is installed by power tool, the bent part 23 will form a limit with the T-shaped head to prevent the T-bolt 31 from rotating on the rectangular tube 1, thereby avoiding slippage during the tightening of the nut and making the installation process more convenient and faster.

[0041] To facilitate on-site positioning and installation, the first circular through hole 221 and the second circular through hole 12 are both circular holes, and the two second mounting holes 5 are set as waist holes, and are symmetrically distributed with the middle position of the flat plate 22 as the central axis. Thus, after the first fastener 3 is installed, the component connector 2 is symmetrically set relative to the rectangular tube 1, and the waist holes can be used for fine adjustment when installing the photovoltaic module.

[0042] In addition, such as Figure 1 As shown, a photovoltaic module installation mechanism is also provided, including the novel purlin described above, as well as U-bolts 6 and a main beam 4. The U-bolts 6 pass through the rectangular tube 1 to fix the purlin to the top of the main beam 4.

[0043] Specifically, a third mounting hole 61 for installing U-bolts 6 is provided in the middle of the rectangular tube. When installing the new purlin, the U-bolts 6 are engaged on the outside of the main beam 4, and the top of the U-bolts 6 passes through the third mounting hole 61 and is locked with a nut.

[0044] The above are preferred embodiments of the present invention. The basic principles, main features, and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope thereof. All such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
