DETAILED DESCRIPTION

[0018] The utility model will be further explained in detail in combination with the drawings and embodiments:

[0019] As Figs. 1-3The auxiliary support device for tracking support of the photovoltaic power station shown comprises a diagonal pull rod 1, a conversion part 2, a horizontal pull rod 3 and a third base 6, the bottom end of the diagonal pull rod 1 is detachably connected with a second base 5, and the top end of the diagonal pull rod 1 is detachably connected with the third base 6 through a flange, the outer end of the diagonal pull rod 1 is integrally formed with the conversion part 2, the end of the conversion part 2 away from the diagonal pull rod 1 is detachably connected with the horizontal pull rod 3 through a flange, the end of the horizontal pull rod 3 away from the conversion part 2 is detachably connected with a first base 4, the upper side of the third base 6 is provided with a pull rod clamp 7, the pull rod clamp 7 comprises an upper clamp 701 and a lower clamp 702, the upper clamp 701 and the lower clamp 702 are mutually symmetrical, and the bottom end of the upper clamp 701 is fixedly connected with a support 704, the support 704 and the third base 6 are detachably connected, and the inner cavities of the upper clamp 701 and the lower clamp 702 are both provided with bearings 8.

[0020] The existing tracking photovoltaic support is mostly fixed with a concrete foundation through bolt connection at the bottom and connected with a photovoltaic panel and a support keel through a transmission shaft at the top. Since the photovoltaic panel is large and rotates following the light, the support not only bears the dead load of the whole system, but also bears more uneven external loads such as wind load and torque generated by transmission, which makes the support bear too heavy load in long-term use and easily fall down or break in extreme weather.

[0021] In the scheme, the material of the diagonal pull rod 1 can be a 80*80*6 Q235B national standard hot-dip galvanized square tube, which is cut and processed according to the design size measured on site, needs to meet the design requirements of the drawing, and the surface is cleaned to remove burrs before being assembled with other parts.

[0022] The material of the horizontal pull rod 3 can also be a 80*80*6 Q235B national standard hot-dip galvanized square tube, and the processing process includes cutting, drilling and punching processes to ensure that the horizontal pull rod 3 meets the design requirements. These processes need to be accurately executed to ensure that the size and shape of the horizontal pull rod 3 are accurate. In the assembly stage, the inclination angle and direction of the horizontal pull rod 3 need to be accurately positioned to ensure that it can correctly support the photovoltaic panel and follow the movement track of the sun. After installation is completed, the photovoltaic tracking support needs to be debugged and checked to ensure that it can work normally.

[0023] In order to protect the horizontal pull rod 3 from corrosion and oxidation and prolong its service life, the scheme designs surface treatment and coating for the horizontal pull rod 3, which includes sandblasting, deburring, cleaning and other processes, and then spraying. At present, baking paint is commonly used for coating of photovoltaic tracking supports.

[0024] The material of the pull rod clamp hoop 7 can be a 140*140*8 Q235B hot-dip galvanized steel plate, which is formed by die stamping once to ensure accuracy and material performance is not damaged. The pull rod clamp hoop 7 is used to connect the photovoltaic panel support and the auxiliary device.

[0025] In the scheme, the connections between the inclined pull rod 1, the conversion part 2, the horizontal pull rod 3, the first base 4, the second base 5, the third base 6, and the pull rod clamp hoop 7 are detachably connected by bolt connectors. Bolt connection has become an important way in mechanical connection. It is not only convenient to disassemble, but also can better release the internal stress of each workpiece caused by rigid connection, which is very important for steel members. It can increase the service life and make the structure more safe and stable.

[0026] The conversion part 2 is arranged at one-third of the bottom of the inclined pull rod 1. In this way, the inclined pull rod 1, the conversion part 2, and the horizontal pull rod 3 together form a very stable triangular structure, which can maximize the stability of the support system.

[0027] The pair of bearings 8 are symmetrical to each other and are arranged in a semi-cylindrical structure. The ends of the pair of bearings 8 away from each other are arranged in an arc shape matching the inner walls of the upper hoop 701 and the lower hoop 702. The ends of the pair of bearings 8 close to each other are provided with a limiting groove 9.

[0028] In the scheme, the pair of bearings 8 are arranged on the inner walls of the bearings 8, cooperating with the fixed extrusion of the bearings 8 to clamp and fix the photovoltaic panel support inside the pair of limiting grooves 9, realizing the stable connection of the photovoltaic panel and the support device.

[0029] The ends of the upper hoop 701 and the lower hoop 702 close to each other are fixedly connected with a plurality of connecting pieces 703. The upper hoop 701 and the lower hoop 702 are detachably connected through the plurality of connecting pieces 703.

[0030] In the scheme, the plurality of connecting pieces 703 are connected by bolt connectors. The tighter the connection, the stronger the clamping force of the upper hoop 701 and the lower hoop 702 on the bearings 8, and the more secure the fixation of the photovoltaic panel.

[0031] The inclined pull rod 1 includes a first inclined rod 101 and a second inclined rod 102. The first inclined rod 101 and the second inclined rod 102 are detachably connected by flanges.

[0032] In the scheme, considering that the inclined pull rod 1 is relatively long, it is divided into the first inclined rod 101 and the second inclined rod 102 for assembly, which can be transported in a detachable manner to provide convenience for transportation.

[0033] The material of the bearing 8 is ultra-high molecular polyethylene.

[0034] In the scheme, considering that the bearing 8 is a core component of the auxiliary device, the material thereof is set to be ultra-high molecular polyethylene, the ultra-high molecular polyethylene has high tensile strength and impact strength, good wear resistance, small friction coefficient, can be self-lubricated, can resist chemical media and work in ultra-low temperature, and is very suitable for use in severe cold regions.

[0035] The specific implementation process is as follows:

[0036] During assembly, first, the components are transported to the location where the photovoltaic panel needs to be installed, the first inclined rod 101, the second inclined rod 102, the horizontal pull rod 3, the first base 4, the second base 5, the third base 6 and the pull rod clamp 7 are connected and assembled through bolt connections and flanges, then the inclined pull rod 1 and the horizontal pull rod 3 are fixed to the required installation position of the photovoltaic panel through the second base 5 and the first base 4 respectively, the inclination angle and direction of the inclined pull rod 1 and the horizontal pull rod 3 are determined to ensure that they can correctly support the photovoltaic panel and follow the movement track of the sun, then a pair of bearings 8 are respectively buckled inside the upper clamp 701 and the lower clamp 702, the photovoltaic panel and its support are clamped in a pair of limiting grooves 9, and the multiple connecting pieces 703 on the upper clamp 701 and the lower clamp 702 are tightened through bolt connections to extrude the pair of bearings 8, thereby fixing the photovoltaic panel support, after installation is completed, the photovoltaic tracking support is debugged and checked to ensure that it can work normally, which includes checking the installation position, fastening degree and connection condition with other components of the inclined pull rod 1 and the horizontal pull rod 3, and during the debugging process, the tracking accuracy and response speed of the tracking system also need to be tested to ensure that it can meet the design requirements.
