Description
Technical Field
[0001] The utility model belongs to the technical field of photovoltaic brackets, and in particular relates to a photovoltaic bracket purlin and a photovoltaic bracket suitable for sloped land. Background Art
[0002] With the continuous development of the new energy industry and the continuous optimization of the energy structure, the proportion of new clean energy represented by photovoltaic power generation is increasing. Photovoltaic brackets are an important part of photovoltaic power stations. Traditional fixed photovoltaic brackets are also developing in the direction of lower cost, easier installation, safer structure and stronger adaptability to slopes.
[0003] The photovoltaic support structure is mostly composed of supporting purlins and diagonal beams. The supporting purlins are fixed to the diagonal beams through purlin support components. Although the purlin support components account for a small proportion of the cost, they are the most critical nodes of the entire fixed support, playing the two major functions of slope conversion and load bearing.
[0004] At present, photovoltaic bracket purlins are often processed by cutting angle steel, drilling holes and doing relevant anti-corrosion work. They are installed and fixed on the diagonal beams. The purlins are placed at the right angle formed between the purlin bracket and the diagonal beam. After adjustment, they are fixed with bolts.
[0005] That is, although the current photovoltaic bracket purlin supports are fast to process, simple in process and low in cost, they have poor adaptability to slopes, especially large east-west slopes. For traditional photovoltaic bracket purlin supports, the purlins need to be tilted, and the relative positions are adjusted through the oblong holes on the purlin supports and purlins. At this time, the purlins and the diagonal beams are not in close contact with each other, but in line contact between the bottom surface of the purlin and the edge of the diagonal beam, which greatly weakens the load-bearing capacity of the fixed photovoltaic bracket and reduces the reliability and stability of the bracket.
[0006] As for some of the current new purlin support structures that use hinged and rotating shaft types, by lifting the purlins so that they no longer contact the diagonal beams, the rotation and tilting of the purlins when installed on an east-west slope is achieved by the hinge structure at the connection node between the purlins and the purlin support. Although this method can better solve the problem of purlin rotation when adapting to slopes, it increases the cost of the purlin support, and the structure of the node is more complex and the stress conditions are more severe. When simply aiming to improve the slope adaptability of the fixed bracket, it cannot take into account the production process and installation process, and it also has limitations.
[0007] With the continuous development of the new energy industry and the continuous optimization of the energy structure, the current photovoltaic brackets are gradually shifting to high-altitude and complex terrain areas. There is an urgent need for photovoltaic brackets that can adapt to slopes while taking into account good structural safety, production technology and installation technology. Utility Model Content
[0008] The purpose of the present utility model is to overcome the defects of the existing technology and provide a photovoltaic bracket purlin support and photovoltaic bracket that are adaptable to slopes. A first mounting hole and an arc-shaped strip hole are simultaneously opened on the first plate surface where the photovoltaic bracket purlin support is connected to the purlin. The arc-shaped strip hole is composed of a plurality of continuous and interconnected third mounting holes, so that the purlin can rotate east-west around the first mounting hole of the photovoltaic bracket purlin support, adapting to various terrains, greatly improving the terrain adaptability of the fixed bracket, and locking through the arc-shaped strip hole makes the structure more stable. At the same time, the design of the arc-shaped strip hole improves the stability of the purlin when adjusting the angle, and the two-point contact connection method also strengthens the strength of the photovoltaic bracket structure.
[0009] The purpose of this utility model is achieved through the following technical solutions:
[0010] A photovoltaic support purlin support adapted for sloped land includes a purlin support body for fixing purlins and diagonal beams, the purlin support body including a first plate surface and a second plate surface perpendicular to each other, the first plate surface having a first mounting hole for connecting to the purlin, and the second plate surface having a second mounting hole for connecting to the diagonal beam;

The centers of the plurality of third mounting holes are on the same arc line, and the center of the arc line is coincident with the center of the first mounting hole. The arc-shaped strip hole is connected to the purlin through a connecting piece passed through the third mounting hole, and the width of the interconnection point between two adjacent third mounting holes is smaller than the diameter of the connecting piece.
[0012] In one embodiment, the middle point of the arc-shaped strip hole and the center of the first mounting hole are located at the same height.
[0013] In one embodiment, the first plate surface and the second plate surface have the same width, and both widths are greater than the width of the oblique beam.
[0014] In one embodiment, the connection between the first plate surface and the second plate surface is an arc-shaped transition.
[0015] In one embodiment, the ends of the first plate surface and the second plate surface that are away from each other are both provided with arc chamfers.
[0016] The utility model also provides a photovoltaic support adapted to slopes, comprising the photovoltaic support purlin mentioned above.
[0017] In one embodiment, it also includes an inclined beam and a purlin installed on the inclined beam, and the purlin and the inclined beam are both provided with connecting holes. The inclined beam is connected to the second mounting hole, and the purlin is connected to the first mounting hole and the third mounting hole to adjust the angle between the purlin and the inclined beam.
[0018] In one embodiment, a support tube extending in the vertical direction is further provided in the cavity of the oblique beam, the support tube corresponds to the position of the second mounting hole, and the support tube is sleeved outside the connecting piece located at the second mounting hole.
[0019] The beneficial effects of the present invention are:
[0020] (1) A first mounting hole and an arc-shaped strip hole are simultaneously opened on the first plate surface of the purlin support, so that the purlin can rotate east-west around the first mounting hole of the photovoltaic bracket purlin support, adapting to various terrains, greatly improving the terrain adaptability of the fixed bracket, and at the same time, the arc-shaped strip hole is composed of a plurality of continuous and interconnected third mounting holes, that is, locked by the arc-shaped strip hole, making the structure more stable, and also improving the stability of the purlin when adjusting the angle, and the two-point contact connection method also strengthens the strength of the photovoltaic bracket structure;

[0030] The present invention will be further described below with reference to the accompanying drawings.
[0031] The utility model provides a photovoltaic support purlin that is suitable for slopes, such as Figure 1 and Figure 2 As shown, it includes a purlin support body for fixing the purlin 3 and the diagonal beam 4. The purlin support body includes a first plate surface 1 and a second plate surface 2 that are perpendicular to each other. The first plate surface 1 is provided with a first mounting hole 5 for connecting with the purlin 3, and the second plate surface 2 is provided with a second mounting hole 7 for connecting with the diagonal beam 4.
[0032] The first panel 1 is further provided with an arc-shaped strip hole 6, which has a plurality of third mounting holes that are continuous and interconnected. The centers of the plurality of third mounting holes are on the same arc line, and the center of the arc line coincides with the center of the first mounting hole 5. The arc-shaped strip hole 6 is connected to the purlin 3 by a connector that passes through the third mounting hole. The width of the portion where two adjacent third mounting holes are connected to each other is smaller than the diameter of the connector.
[0033] It should be noted that if Figure 2 As shown, in order to adapt to the slope, the purlin 3 is made of Figure 1 The schematic diagram of the structure with angle adjustment in the conventional installation state is shown. The centers of the multiple third mounting holes are on the same arc line, and the center of the arc is coincident with the center of the first mounting hole 5. That is, under the action of the arc-shaped bar hole 6, the purlin 3 can be rotated in the east-west direction around the first mounting hole 5 of the purlin support body without affecting the strength of the connection. Specifically, in the implementation process, the third mounting holes at appropriate positions can be selected from the arc-shaped bar holes 6 to set the connecting piece according to the angle to be adjusted. The width of the interconnected part of two adjacent third mounting holes is less than the diameter of the connecting piece to limit the connecting piece and ensure the connection strength. The purlin 3 is first connected through the first mounting hole 5, and then the purlin 3 is adjusted to a suitable angle and then locked through the arc-shaped bar hole 6, so that the structure is more stable and the stability of the purlin 3 during angle adjustment is improved. The two-point contact connection method also strengthens the strength of the photovoltaic bracket structure.
[0034] In one embodiment, the middle point of the arc-shaped strip hole 6 and the center of the first mounting hole 5 are located at the same height, that is, Figure 1 and Figure 2 As shown, the arc-shaped strip hole 6 is located to the right of the first mounting hole 5. The arc-shaped strip hole 6 can also be located to the left of the first mounting hole 5. The midpoint of the arc-shaped strip hole 6 and the center of the first mounting hole 5 can be at the same height. That is, under the premise of meeting the adjustment angle of the purlin 3, the design area of the first plate surface 1 is reduced, thereby reducing the volume of the entire purlin support, reducing the required materials, and reducing the production cost.
[0035] In one embodiment, Figure 1 and Figure 2 As shown, the widths of the first plate surface 1 and the second plate surface 2 are the same, and both widths are greater than the width of the oblique beam 4. That is, the widths of the first plate surface 1 and the second plate surface 2 are designed to be greater than the width of the oblique beam 4. On the one hand, it is convenient to open the first mounting hole 5 and the arc-shaped strip hole 6 on the first plate surface 1, and on the other hand, it improves the overall structural strength.
[0036] In one embodiment, Figure 1 and Figure 2 As shown, the connection between the first plate surface 1 and the second plate surface 2 is an arc-shaped transition, and the ends of the first plate surface 1 and the second plate surface 2 that are away from each other are both provided with arc-shaped chamfers, so that the outline of the purlin support body can be more rounded, thereby improving the safety of personnel during the installation process;
[0037] The utility model also provides a photovoltaic support adapted to slopes, comprising the above-mentioned photovoltaic support purlin support, and further comprising an inclined beam 4 and a purlin 3 mounted on the inclined beam 4, wherein the purlin 3 and the inclined beam 4 are provided with connection holes, the inclined beam 4 is connected to the second mounting hole 7, and the purlin 3 is connected to the first mounting hole 5 and the third mounting hole to adjust the angle between the purlin 3 and the inclined beam 4;
[0038] Furthermore, a support tube 9 extending in the vertical direction is further provided in the cavity of the oblique beam 4. The support tube 9 corresponds to the position of the second mounting hole 7, and the support tube 9 is sleeved outside the connecting piece located in the second mounting hole 7, that is, Figure 1 As shown, the support tube 9 is arranged in the cavity of the oblique beam 4. When a connecting piece such as a bolt is arranged at the second mounting hole 7 to connect the purlin support body and the oblique beam 4, one end of the bolt passes through the second mounting hole 7 and the oblique beam 4 in sequence and enters the support tube 9. Similarly, a bolt is also provided on the other side of the oblique beam 4 and penetrates the support tube 9. The provision of the support tube 9 further improves the strength of the oblique beam 4, thereby extending the service life of the entire photovoltaic bracket, so that it can be used in high-altitude and complex terrain areas, which is conducive to the development of the new energy industry.
