Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, and more specifically, to a novel purlin device used in photovoltaic power generation projects. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It mainly consists of three parts: solar panels (modules), controllers and inverters. The main components are composed of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules. Combined with power controllers and other components, 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 device is mainly arranged horizontally on the bracket or base, and then the solar panel is placed on the purlin. Then the threaded bolts on the purlin are moved to the corresponding installation position, and then the bolts are passed through the solar panel and screwed into the threaded sleeve to achieve the installation and fixation of the solar panel.

[0003] After the existing purlin device is installed and fixed to the solar panel by means of threaded bolts, its lateral fixation mainly depends on the tightening tightness of the bolts and the threaded bolts. However, the lateral fixation effect is not ideal and lateral displacement is likely to occur, resulting in separation between the solar panels, thereby affecting the assembly effect of the solar panels. In view of this, we propose a new purlin device for photovoltaic power generation projects. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the existing technology, adapt to actual needs, and provide a new purlin device for photovoltaic power generation projects to solve the technical problems that the current purlin device has poor lateral fixing effect and is prone to displacement.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a new purlin device for photovoltaic power generation projects, comprising a purlin body, wherein a plurality of groups of hexagonal screw sleeves are slidably arranged inside the purlin body, a fixing bolt is screwed into the top of the hexagonal screw sleeve, a first rectangular hole is opened at the center of the front and rear sides of the hexagonal screw sleeve, a transverse positioning block is movably arranged inside the first rectangular hole, a triangular positioning strip is arranged on the opposite side of the transverse positioning block, and tooth grooves are arranged on the front and rear sides of the interior of the purlin body;

[0006] The side of the transverse positioning block facing away from the triangular positioning strip is provided with an arc-shaped inclined surface and an arc-shaped vertical surface. The inclination angle of the arc-shaped inclined surface is an obtuse angle, and the arc-shaped inclined surface is located above the arc-shaped vertical surface.

[0007] The utility model is designed with structures such as tooth grooves, transverse positioning blocks and conical end heads. Therefore, when the fixing bolt passes through the solar panel and is screwed together with the hexagonal nut, as the fixing bolt goes deeper into the hexagonal nut, the conical end head at the bottom end of the fixing bolt will push the two sets of transverse positioning blocks to move backwards. At this time, the triangular positioning strips of the transverse positioning blocks will directly fit into the corresponding tooth grooves inside the main body of the strip, thereby realizing transverse positioning of the hexagonal nut, making it impossible for it to move laterally, thereby greatly ensuring the fixing effect of the fixing bolt and the hexagonal nut on the solar panel, thereby effectively avoiding the occurrence of transverse displacement of the solar panel after installation and fixation; the utility model also provides a transverse positioning block on the hexagonal nut The arc-shaped inclined surface and the arc-shaped vertical surface, the arc-shaped inclined surface is located at the top, and the arc-shaped vertical surface is located at the bottom. Therefore, in the process of screwing the fixing bolt into the hexagonal nut, with the cooperation of the arc-shaped inclined surface and the frustum end of the fixing bolt, the two sets of lateral positioning blocks can be pushed outward more smoothly without jamming, and the fixing bolt can be screwed into the hexagonal nut smoothly until the two sets of lateral positioning blocks are completely displaced into the first rectangular hole. At this time, the arc-shaped vertical surface and the surface of the fixing bolt are pressed over a large area, thereby better ensuring the stability of the triangular positioning strip on the lateral positioning block inserted into the tooth groove. Therefore, with the cooperation of the arc-shaped inclined surface and the arc-shaped vertical surface, the use effect of the lateral positioning block can be further improved.

[0008] Preferably, a frustum-shaped end head is arranged at the bottom end of the fixing bolt, and the top area of ​​the frustum-shaped end head is larger than the bottom area thereof, and the top diameter of the frustum-shaped end head is the same as the diameter of the fixing bolt.

[0009] Preferably, concave frames are arranged at both ends of the bottom of the sandalwood bar body, and mounting bolts are arranged in the concave frames.

[0010] Preferably, a reset structure is arranged on the top and bottom of the hexagonal screw sleeve, and the reset structure includes an elastic ring structure and two groups of connecting rods. The two groups of connecting rods are symmetrically arranged on the elastic ring structure, and the connecting rods are connected to the corresponding lateral positioning blocks.

[0011] Preferably, the top and bottom of the hexagonal screw sleeve are provided with hexagonal grooves, the elastic ring structure is located inside the hexagonal grooves, two groups of symmetrical second rectangular holes are provided on the hexagonal grooves, and the second rectangular holes are connected to the first rectangular holes, and the connecting rod passes through the second rectangular holes.

[0012] Preferably, the elastic circular ring structure comprises two groups of semicircular rings and springs, and the springs are arranged at opposite ends of the two groups of semicircular rings.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is designed with structures such as tooth grooves, transverse positioning blocks and frustum end heads. Therefore, when the fixing bolt passes through the solar panel and is screwed together with the hexagonal screw sleeve, as the fixing bolt goes deeper into the hexagonal screw sleeve, the frustum end head at the bottom of the fixing bolt will push the two sets of transverse positioning blocks to move back to each other. At this time, the triangular positioning strips of the transverse positioning blocks will directly fit into the corresponding tooth grooves inside the main body of the purlin, thereby realizing the transverse positioning of the hexagonal screw sleeve and preventing it from being displaced laterally, thereby greatly ensuring the fixing effect of the fixing bolts and the hexagonal screw sleeve on the solar panel, thereby effectively avoiding the transverse displacement of the solar panel after installation and fixation, solving the technical problem that the current purlin device has poor transverse fixing effect and is prone to displacement. Therefore, the utility model has the advantage of better fixing effect on the solar panel.

[0015] 2. The utility model also provides an arc-shaped inclined surface and an arc-shaped vertical surface on the hexagonal nut sleeve of the horizontal positioning block, the arc-shaped inclined surface is located at the top, and the arc-shaped vertical surface is located at the bottom. Therefore, in the process of screwing the fixing bolt into the hexagonal nut sleeve, the two groups of horizontal positioning blocks can be pushed outward more smoothly with the cooperation of the arc-shaped inclined surface and the frustum end of the fixing bolt, and there will be no jamming phenomenon. In addition, the fixing bolt can be screwed into the hexagonal nut sleeve smoothly until the two groups of horizontal positioning blocks are completely displaced into the first rectangular hole. At this time, the arc-shaped vertical surface and the surface of the fixing bolt are pressed against each other over a large area, thereby better ensuring the stability of the triangular positioning strip on the horizontal positioning block inserted into the tooth groove. Therefore, with the cooperation of the arc-shaped inclined surface and the arc-shaped vertical surface, the use effect of the horizontal positioning block can be further improved.

[0023] like Figures 1 to 5 As shown, the utility model relates to a new type of purlin device for photovoltaic power generation projects, including a purlin body 1, a plurality of groups of hexagonal screw sleeves 3 are arranged in a sliding manner inside the purlin body 1, a fixing bolt 4 is screwed into the top of the hexagonal screw sleeve 3, a first rectangular hole 301 is opened in the center of the front and rear sides of the hexagonal screw sleeve 3, a horizontal positioning block 5 is movably arranged inside the first rectangular hole 301, a triangular positioning strip 501 is arranged on the back side of the horizontal positioning block 5, and a tooth groove 101 is arranged on the front and rear sides of the interior of the purlin body 1; a frustum end head 401 is arranged at the bottom end of the fixing bolt 4, and the top area of ​​the frustum end head 401 is larger than its bottom area, and the top diameter of the frustum end head 401 is the same as the diameter of the fixing bolt 4; when installing the solar panel, first fix the purlin body 1 to the external bracket or base, and then place the solar panel When the fixing bolt 4 passes through the solar panel and is screwed into the hexagonal screw sleeve 3, the fixing bolt 4 goes deeper into the hexagonal screw sleeve 3. At this time, the frustum end 401 at the bottom end of the fixing bolt 4 will push the two sets of lateral positioning blocks 5 to move back to each other. At this time, the triangular positioning strip 501 of the lateral positioning block 5 will be directly stuck in the corresponding tooth groove 101 inside the main body 1 of the sandalwood bar, thereby realizing the lateral positioning of the hexagonal screw sleeve 3 and preventing it from being displaced laterally. This greatly ensures the fixing effect of the fixing bolt 4 and the hexagonal screw sleeve 3 on the solar panel, and can effectively avoid the occurrence of lateral displacement of the solar panel after installation and fixation.

[0024] Specifically, concave frames 2 are arranged at both ends of the bottom of the sandalwood bar body 1, and mounting bolts 201 are arranged in the concave frames 2. The concave frames 2 at the bottom of the sandalwood bar body 1 are docked with the external bracket or platform, and then screwed and fixed with the external bracket or platform by the mounting bolts 201.

[0025] The cam 502 is provided with a plurality of cams 503 on the top of the cam 504, and the cam 504 is provided with a plurality of cams 503 on the top of the cam 504.

[0026] In an embodiment of the present invention, a reset structure 6 is arranged on the top and bottom of the hexagonal screw sleeve 3, and the reset structure 6 includes an elastic ring structure 7 and two groups of connecting rods 8. The two groups of connecting rods 8 are symmetrically arranged on the elastic ring structure 7, and the connecting rods 8 are connected to the corresponding lateral positioning blocks 5; a hexagonal groove 303 is provided on the top and bottom of the hexagonal screw sleeve 3, and the elastic ring structure 7 is located inside the hexagonal groove 303. Two groups of symmetrical second rectangular holes 302 are provided on the hexagonal groove 303, and the second rectangular holes 302 are connected to the first rectangular holes 301, and the connecting rods 8 pass through the second rectangular holes 302; the elastic ring structure 7 includes two groups of semicircular rings 701 and a spring 702. The spring 702 is arranged at the opposite ends of the two groups of semicircular rings 701. When displacement and fixation are required When the bolt 4 and the hexagonal nut 3 are engaged, the fixing bolt 4 can be screwed to separate the bottom conical end 401 from the horizontal positioning block 5. At this time, under the action of the spring 702, the two groups of semicircular rings 701 are relatively displaced to reset, and then the two groups of semicircular rings 701 can drive the two groups of horizontal positioning blocks 5 to reset through the connecting rod 8, so that the triangular positioning strip 501 of the horizontal positioning block 5 is separated from the tooth groove 101. The personnel can slide and adjust the fixing bolt 4 and the hexagonal nut 3 more smoothly without any jamming, and the elastic ring structure 7 will not block the screw hole of the hexagonal nut 3. Therefore, the reset adjustment of the horizontal positioning block 5 can be achieved without affecting the normal screwing of the fixing bolt 4 and the hexagonal nut 3.

[0027] When the solar panel is installed, the main body 1 of the purlin is fixed to the external bracket or base, and the solar panel is placed on the main body 1 of the purlin. Then, the fixing bolts 4 and the hexagonal screw sleeves 3 are moved to the appropriate position. Then, the fixing bolts 4 are passed through the solar panel and screwed together with the hexagonal screw sleeves 3 to fix the solar panel. When the fixing bolts 4 pass through the solar panel and are screwed together with the hexagonal screw sleeves 3, as the fixing bolts 4 go deeper into the hexagonal screw sleeves 3, the frustum end 401 at the bottom end of the fixing bolts 4 will push the two sets of lateral positioning blocks 5 to move back to back. At this time, the triangular positioning strips 501 of the lateral positioning blocks 5 will directly fit into the corresponding tooth grooves 101 inside the main body 1 of the purlin, thereby realizing lateral positioning of the hexagonal screw sleeves 3, making it impossible for it to move laterally, thereby greatly ensuring the fixing effect of the fixing bolts 4 and the hexagonal screw sleeves 3 on the solar panel, and can effectively avoid the occurrence of lateral displacement of the solar panel after installation and fixation.

[0028] Secondly, in the process of screwing the fixing bolt 4 into the hexagonal nut 3, with the cooperation of the arc-shaped inclined surface 502 and the frustum end 401 of the fixing bolt 4, the two sets of horizontal positioning blocks 5 can be pushed outward more smoothly without jamming, and the fixing bolt 4 can be screwed into the hexagonal nut 3 smoothly until the two sets of horizontal positioning blocks 5 are completely displaced into the first rectangular hole 301. At this time, the arc-shaped vertical surface 503 and the surface of the fixing bolt 4 are pressed against each other over a large area, thereby better ensuring the stability of the triangular positioning strip 501 on the horizontal positioning block 5 inserted into the tooth groove 101. Therefore, with the cooperation of the arc-shaped inclined surface 502 and the arc-shaped vertical surface 503, the use effect of the horizontal positioning block 5 can be further improved.

[0029] Finally, when it is necessary to displace the fixing bolt 4 and the hexagonal nut 3, the fixing bolt 4 can be screwed to separate the bottom conical end 401 from the horizontal positioning block 5. At this time, under the action of the spring 702, the two groups of semicircular rings 701 are relatively displaced and reset, and then the two groups of semicircular rings 701 can drive the two groups of horizontal positioning blocks 5 to reset through the connecting rod 8, so that the triangular positioning strip 501 of the horizontal positioning block 5 is separated from the tooth groove 101. Personnel can slide and adjust the fixing bolt 4 and the hexagonal nut 3 more smoothly without getting stuck, and the elastic ring structure 7 will not block the screw hole of the hexagonal nut 3. Therefore, the reset adjustment of the horizontal positioning block 5 can be achieved without affecting the normal screwing of the fixing bolt 4 and the hexagonal nut 3.
