Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, specifically relating to a novel purlin device for photovoltaic power generation projects. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three parts: solar panels, controllers, and inverters. The main components are made of electronic components. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as power controllers, a photovoltaic power generation device is formed. In photovoltaic power generation projects, the installation of solar panels usually requires the use of purlin devices. The purlin devices are mainly arranged horizontally on supports or bases. Then, the solar panels are placed on the purlins, and the bolts on the purlins are moved to the corresponding installation positions. Finally, the bolts are passed through the solar panels and screwed into the bolt sleeves to achieve the installation and fixation of the solar panels.

[0003] For example, in the Chinese utility model announcement CN223309791U entitled "A Novel Purlin Device for Photovoltaic Power Generation Projects," a purlin body is included. The aforementioned prior art, through the design of toothed grooves, transverse positioning blocks, and frustum-shaped ends, allows the triangular positioning strip of the transverse positioning block to directly engage with the corresponding toothed groove inside the purlin body, thereby achieving transverse positioning of the hexagonal threaded sleeve and preventing it from making transverse displacement. However, when the purlin is long and needs to be spliced, the efficiency is low. Therefore, in order to reduce splicing time, a novel purlin device for photovoltaic power generation projects is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of purlin device for photovoltaic power generation projects that has a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A novel purlin device for photovoltaic power generation projects includes a purlin body, with splicing components provided on the outer wall of the purlin body, multiple mounting grooves I on the side wall of the purlin body, and multiple mounting grooves II on the bottom of the purlin body.

[0006] As a further optimization of this utility model, the splicing assembly includes a U-shaped purlin bracket that is detachably connected to the outer wall of two adjacent purlin bodies. The inner wall of the U-shaped purlin bracket is threaded with two bolts, and the outer wall of each of the two bolts is movably fitted with a limit block.

[0007] As a further optimization of this utility model, the bottom of the two limiting blocks abuts against the inner bottom surface of the two adjacent purlin bodies, and the limiting blocks are distributed perpendicularly to the mounting groove at a 90-degree angle. Two sets of limiting holes are opened on the outer side of the U-shaped purlin bracket.

[0008] As a further optimization of this utility model, a U-shaped bolt is slidably connected to the inner side of one set of limiting holes, penetrating the inner wall of the mounting groove on two adjacent purlin bodies. One end of the U-shaped bolt is detachably connected to a washer that abuts against the inner side of the purlin body, and one end of the U-shaped bolt is threadedly connected to a nut that abuts against the washer.

[0009] As a further optimization of this utility model, a sliding groove is provided on the inner side of the purlin body, and the bottom of the U-shaped purlin support is movably connected to the inclined beam.

[0010] As a further optimization of this utility model, a plastic wing nut is detachably connected inside the sliding groove, and one end of the plastic wing nut is threaded through the inner wall of the second mounting groove.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model involves screwing bolts onto the inner wall of a U-shaped purlin bracket to make the limiting block parallel to the U-shaped purlin bracket laterally. Then, the second mounting groove on the purlin body is slid into the limiting block, allowing the bottom of the purlin body to be placed on the inner wall of the U-shaped purlin bracket. The bolts are then rotated to make the limiting block perpendicular to the second mounting groove. This process is repeated to complete the splicing of multiple sets of purlin bodies. No complex technology or equipment is required, which shortens the on-site installation time, reduces reliance on professional welders and other manpower, and lowers labor costs. At the same time, precise splicing reduces material waste and indirectly controls investment.

[0012] 2. This utility model improves the splicing tightness by sliding the U-bolt along the limiting hole and through the first mounting groove, installing the washer, and then tightening the nut. The nut squeezes the washer against the side wall of the purlin body, ensuring the overall stability of the purlin structure, avoiding damage to the photovoltaic panel, and saving operation and maintenance costs.

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1: As Figure 1 , Figure 3 As shown, a novel purlin device for photovoltaic power generation projects includes a purlin body 1, which provides a foundation for photovoltaic panel installation. A splicing assembly 2 is provided on the outer wall of the purlin body 1, enabling the connection and fixation of the purlin body 1. The splicing assembly 2 includes a U-shaped purlin bracket 201, which provides a foundation for splicing. The inner wall of the U-shaped purlin bracket 201 is detachably connected to the outer walls of two adjacent purlin bodies 1 for easy maintenance and replacement. Two bolts 202 are threadedly connected to the inner wall of the U-shaped purlin bracket 201, providing a base for rotation. Limit blocks 203 are movably sleeved on the outer walls of both bolts 202. After the bolts 202 are threadedly connected to the U-shaped purlin bracket 201, they drive the limit blocks 203 to rotate.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the side walls of the purlin body 1 are provided with multiple mounting grooves 2 and 4. The mounting grooves 2 and 4 facilitate the selection of appropriate positions for the limiting blocks 203 to pass through. The bottoms of the two limiting blocks 203 abut against the inner bottom surfaces of the two adjacent purlin bodies 1, so that the purlin body 1 can slide in for installation and its longitudinal displacement can be restricted after abutment. The limiting blocks 203 and the mounting grooves 2 and 4 are distributed at a 90-degree angle. The outer side of the U-shaped purlin bracket 201 is provided with two sets of limiting holes 204. The limiting holes 204 are used to provide sliding installation channels. The inner side of one set of limiting holes 204 is slidably connected with U-bolts 205 for subsequent installation. The side walls of the two adjacent purlin bodies 1 are provided with multiple mounting grooves 1 and 3. The mounting grooves 1 and 3 can be adapted to the installation of U-bolts 205 in different positions.

[0018] like Figure 1 , Figure 2 , Figure 4As shown, the outer wall of the U-bolt 205 slides through the inner wall of the mounting groove 3, which can connect the U-shaped purlin bracket 201 to the purlin body 1. One end of the U-bolt 205 is detachably connected to a washer 206. The washer 206 is used to increase the force-bearing area. The inner side of the washer 206 abuts against the inner side of the purlin body 1 to avoid damage to the inner wall of the purlin body 1. One end of the U-bolt 205 is threadedly connected to a nut 207. Tightening the nut 207 achieves fastening. One side of the nut 207 abuts against the outer side of the washer 206. After abutting, the washer 206 is squeezed to enhance the tightness of the connection.

[0019] like Figure 1 , Figure 2 As shown, a sliding groove is provided on the inner side of the purlin body 1. The sliding groove is used to provide installation space. The bottom of the U-shaped purlin bracket 201 is movably connected to the inclined beam. The movable connection facilitates the adjustment of the relative position of the U-shaped purlin bracket 201 and the inclined beam. A plastic wing nut is detachably connected in the sliding groove. The plastic wing nut is composed of a plastic wing and a metal threaded sleeve. By manually turning the plastic wing, the metal threaded sleeve is engaged with the screw. The fastening is achieved by the friction and positive pressure between the threads. The plastic wing nut is existing technology and will not be described in detail in this utility model. One end of the plastic wing nut is threaded through the inner wall of the mounting groove 4. The photovoltaic panel is fixed to the top of the purlin body 1 by the plastic wing nut.

[0020] It should be noted that, in the use of this new type of purlin device for photovoltaic power generation projects, the U-shaped purlin bracket 201 is first installed on the inclined beam. Then, bolts 202 are screwed onto the inner wall of the U-shaped purlin bracket 201 so that the limiting block 203 is parallel to the U-shaped purlin bracket 201 laterally. Then, the mounting groove 4 on the purlin body 1 is slid into the limiting block 203 so that the bottom of the purlin body 1 is placed on the inner wall of the U-shaped purlin bracket 201. Then, the bolts 202 are rotated so that the limiting block 203 is perpendicular to the mounting groove 4. Then, the above operation is repeated so that multiple sets of purlin bodies 1 are spliced ​​together.

[0021] When reinforcing the spliced ​​parts, first slide the U-bolt 205 into the mounting groove 3 through the set of limiting holes 204 that are easy to install, and then install the washer 206 so that the nut 207 can be tightened. Then the nut 207 presses the washer 206 against the side wall of the purlin body 1, making the splice more secure.

[0022] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
