[0072] The second end of the hoop assembly 6 is connected to the diagonal beam 3 through a second diagonal brace 8.

[0073] In this embodiment, the lower end of the pile foundation 1 is fixed to a relatively hard foundation. The diameter of the pile foundation 1 can be 300 mm. An end plate is provided in the pile foundation 1, and its specification model can be 210*180*10, as Figures 12 to 13As shown in the figure, the number 6 in the figure represents the circumferential fillet welds, the number 3 represents the fillet welds on both sides. The column 2 is welded to the end plate in the pile foundation 1. The upper end of the pile foundation 1 is fixed with the column 2. The column 2 can be made of C-shaped section steel, and the specification and model can be C-shaped 120*65*15*3, or other models of steel can be selected according to actual needs. The upper part of the column 2 is connected to the inclined beam 3 by bolts. The column 2 is provided with an elliptical hole with a major axis of 50 mm and a minor axis of 16 mm. The inclined beam 3 is provided with a round hole Φ16, and an external hexagonal bolt M14*60 is used for connection. When connecting, two nuts, a large flat washer, a flat washer, and a spring washer are equipped. A number of spaced purlin connectors 4 are arranged on the inclined beam 3. The inclined beam 3 is made of C-shaped 90*40*10*2 steel. The inclined beam 3 is connected to the component 5 through the purlin connector 4. The component 5 is a solar panel, and a hoop assembly 6 connected to the pile foundation 1; the first end of the hoop assembly 6 is connected to the inclined beam 3 through the first brace 7. The first brace 7 can be made of C-shaped 50*40*2 steel; the second end of the hoop assembly 6 is connected to the inclined beam 3 through the second brace 8. The second brace 8 can be made of C-shaped 70*50*2 steel, or other profiles of other specifications can be selected as needed.

[0074] In this technical solution, by arranging a number of purlin connectors at intervals and the inclined beams at intervals, it is ensured that after the photovoltaic module is connected to the purlin connector, there is no occlusion on both the front and back sides, improving the power generation efficiency of the photovoltaic module. At the same time, this new structure is simple, has reasonable stress, is easy to construct and implement, and has strong adaptability.

[0075] In an alternative embodiment of the present utility model, the hoop assembly 6 includes a first hoop 61 and a second hoop 62;

[0076] The first hoop 61 and the second hoop 62 are connected to form a ring structure.

[0077] In this embodiment, the hoop assembly 6 includes a first hoop 61 and a second hoop 62. The first hoop 61 can be made of Φ300*5*80*670 steel, or other profiles of other specifications can be selected as needed; the second hoop 62 can be made of Φ300*5*80*450 steel, or other profiles of other specifications can be selected as needed; the two ends of the first hoop 61 and the second hoop 62 are connected by a first bolt 9 to form a ring structure. The first bolt 9 can be an M16*80 bolt, and two nuts, two flat washers, and a spring washer are required during installation.

[0078] As a common connection method, from the structural form, the hoop assembly generally consists of two half rings, and the two half rings are tightly fastened to the connection object by bolts or welding, so as to play a role of connection and fixation.

[0079] In the connection method of the hoop assembly, the entire connecting piece does not need to reserve too much space for expansion and contraction, which means that there will generally be no large displacement or vibration in the parts connected by the hoop assembly; therefore, from this perspective, the connection method of the hoop assembly can be classified as a rigid connection.

[0080] At the same time, the connection method of the hoop assembly also has a certain degree of flexibility. This is because the materials of the hoop assembly and the design of the connecting piece itself have elasticity, enabling the connection method of the hoop assembly to adapt to the displacement and vibration of the connection object to a certain extent, so as to meet some special connection requirements.

[0081] In addition, the hoop connection method has the advantages of low cost and convenient installation. Since the parts connected by the hoop assembly do not need to reserve too much space for expansion and contraction, the stability and rigidity of the connection can be ensured. In this embodiment, the connection method using the hoop assembly 6 can ensure the stability and rigidity of the structural connection.

[0082] In an optional embodiment of the present utility model, the first hoop 61 includes a first part 611 and a second part 612;

[0083] The first part 611 is fixedly connected to the second part 612;

[0084] The second part 612 arches at a preset angle;

[0085] The second part 612 is provided with a first bolt hole 613;

[0088] The fourth part 622 arches at a preset angle;

[0089] The fourth part 622 is provided with a second bolt hole 623, a third bolt hole 624, and a fourth bolt hole 625;

[0090] The first bolt hole 613 and the second bolt hole 623 are vertically aligned;

[0091] The second bolt hole 623 is connected to the first bolt hole 613 through a first bolt 9.

[0092] In this embodiment, the first hoop 61 includes a first part 611 and a second part 612. The first part 611 is a semi-circular ring with a radius of 150 mm. The first part 611 is fixedly connected to the second part 612. The connecting part between the first part 611 and the second part 612 is connected by an arc with a radius that can be 10 mm. The straight section of the second part 612 arches outward slightly by about 1 degree, that is, the second part 612 forms an angle of about 1 degree with the horizontal. The arching position starts from the connecting part between the first part 611 and the second part 612, which is convenient for subsequent force application and makes the connection more firm. The second part 612 is provided with a first bolt hole 613, and the aperture of the first bolt hole 613 can be 17.5 mm. The distance from the central part of the first bolt hole 613 to the end of the second part 612 is 35 mm.

[0093] The second hoop 62 includes a third part 621 and a fourth part 622.

[0094] The third part 621 is a semi-circular ring with a radius of 150 mm. The third part 621 is fixedly connected to the fourth part 622. The connecting part between the third part 621 and the fourth part 622 is connected by an arc with a radius that can be 10 mm. The straight section of the fourth part 622 arches outward slightly by about 1 degree, that is, the fourth part 622 forms an angle of about 1 degree with the horizontal. The arching position starts from the connecting part between the third part 621 and the fourth part 622, which is convenient for subsequent force application and makes the connection more firm. The fourth part 622 is provided with a second bolt hole 623, a third bolt hole 624, and a fourth bolt hole 625. The aperture of the second bolt hole 623 can be 17.5 mm. The third bolt hole 624 and the fourth bolt hole 625 are oval holes with a minor axis of 16 mm and a major axis of 30 mm. The distances from the central part of the second bolt hole 623 to the central parts of the third bolt hole 624 or the fourth bolt hole 625 are 90 mm respectively. The distances from the third bolt hole 624 or the fourth bolt hole 625 to the end of the fourth part 622 are 55 mm respectively. The first bolt hole 613 and the second bolt hole 623 are vertically aligned.

[0095] The arching of the second part 612 at a preset angle and the arching of the fourth part 622 at a preset angle are the same.

[0096] The second bolt hole 623 is connected to the first bolt hole 613 through a first bolt 9. The first bolt 9 can be an M16*80 bolt. Two nuts, two flat washers, and one spring washer are required during installation.

[0097] The bolt consists of a screw rod and a nut, with a simple structure, easy to manufacture and repair. The tightness of the bolt connection can be achieved by adjusting the rotation of the nut, which can meet the needs of different stress situations. The bolt connection has properties such as earthquake resistance and corrosion resistance, which can ensure the firmness and stability of the workpiece.

[0098] By setting a flat washer in the bolt connection, on the one hand, it can increase the connection area. In the bolt connection, since the surface between the bolt head and the connecting piece is not completely flat, there will be irregular surface protrusions or depressions, and the flat washer can fill these protrusions and depressions, making the connection area more uniform, thus reducing the stress concentration on the surface of the connecting piece. On the other hand, it can prevent the locking force marks. In the design of the mechanical properties of the bolt, a maximum locking force is often set to generate a certain pressure under the action of external loads to ensure the reliability of the connection. However, the long-term pressure is likely to cause locking force marks on the surface of the connecting piece, which may lead to connection loosening or failure, and the flat washer can play a buffering role to reduce the possible marks after locking, thereby extending the service life of the connecting piece. In addition, it can also adjust the tightness. Since it is relatively difficult to control the tightness of the bolt connection, if it is too tight or too loose, it will affect the strength and reliability of the connection. By increasing or decreasing parameters such as the number, material, and thickness of the flat washers, the tightness can be adjusted to make the mechanical properties of the bolt connection reach the best state.

[0099] In addition, adding a spring washer can improve the strength and reliability of the bolt connection, and the spring washer can also effectively prevent the bolt from loosening or falling off.

[0100] In an optional embodiment of the present utility model, one end of the first diagonal brace 7 is provided with a fifth bolt hole 71, and the other end is provided with a sixth bolt hole 72;

[0101] The fifth bolt hole 71 is connected through the third bolt hole 624 of the second bolt 10;

[0102] One end of the second diagonal brace 8 is provided with a seventh bolt hole 81, and the other end is provided with an eighth bolt hole 82;

[0103] One end of the diagonal beam 3 is provided with a ninth bolt hole 31, and the other end is provided with a tenth bolt hole 32;

[0104] The sixth bolt hole 72 is connected to the ninth bolt hole 31 through the third bolt 11;

[0105] The eighth bolt hole 82 is connected to the tenth bolt hole 32 through the fourth bolt 12.

[0106] In this embodiment, one end of the first diagonal brace 7 is provided with a fifth bolt hole 71 with a hole diameter of 16 mm, and the other end is provided with a sixth bolt hole 72 with a hole diameter of 16 mm;

[0107] The fifth bolt hole 71 is connected through the second bolt 10 and the third bolt hole 624; one end of the first brace 7 is connected to the hoop assembly 6 through the second bolt 10. The second bolt 10 can be an M14*60 bolt, and two nuts, one large flat washer, one flat washer, and one spring washer are required during installation.

[0108] One end of the second brace 8 is provided with a seventh bolt hole 81 with a diameter of 16 mm, and the other end is provided with an eighth bolt hole 82 with a diameter of 16 mm; one end of the diagonal beam 3 is provided with a ninth bolt hole 31 which is an oval hole with a minor axis of 13 mm and a major axis of 25 mm, and the other end is provided with a tenth bolt hole 32 which is an oval hole with a minor axis of 13 mm and a major axis of 25 mm.

[0113] In this embodiment, the column 2 is welded to the end of the pile foundation 1. A end plate is provided in the pile foundation 1, and its specification model can be a steel plate of 210*180*10. The column 2 is welded to the end plate in the pile foundation 1.

[0114] The column 2 is bolted to the diagonal beam 3. The column is provided with an oval hole with a major axis of 50 mm and a minor axis of 16 mm, and the round hole of the diagonal beam 3 is 16 mm. The column 2 and the diagonal beam 3 can be connected by an M14*60 bolt, and two nuts, one large flat washer, one flat washer, and one spring washer are required during installation.

[0115] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure.

[0116] Compared with traditional methods such as riveting and bolt fastening, welding has lower costs, and the welded workpieces are not easily loosened or disconnected.

[0117] Welding joins workpieces together by heating the workpieces until they melt and forming an oxide skin after cooling. The connection is firm and can withstand high forces and pressures.

[0118] Whether the materials are the same or different, as long as a certain welding area can be formed after heating, welding can be carried out.

[0119] In an alternative embodiment of the present utility model, the purlin connector 4 includes a purlin 41 and an angle purlin support 42.

[0120] The purlin 41 and the angle purlin support 42 are connected by a fifth bolt 13.

[0121] The angle purlin support 42 is connected to the inclined beam 3 by a sixth bolt 14.

[0122] One end of the purlin 41 is connected to the component 5 by a seventh bolt 15.

[0123] In this embodiment, the purlin connector 4 includes a purlin 41 and an angle purlin support 42. The purlin 41 can be made of C-shaped 120*55*15*2 steel, and the angle purlin support 42 can be made of L100*63*6 steel. The purlin 41 and the angle purlin support 42 are connected by a fifth bolt 13. The fifth bolt 13 can be an external hexagon M12*50 bolt, and two nuts, one large flat washer, one flat washer, and one spring washer are required for installation.

[0124] The angle purlin support 42 is connected to the inclined beam 3 by a sixth bolt 14. The sixth bolt 14 can be an external hexagon M12*50 bolt, and two nuts, two flat washers, and one spring washer are required for installation.

[0125] One end of the purlin 41 is connected to the component 5 by a seventh bolt 15. The seventh bolt 15 can be an external hexagon M8*22 bolt, and two nuts, one large flat washer, one flat washer, and one spring washer are required for installation.

[0126] The C-shaped 120*55*15*2 steel indicates that the length of the C-shaped steel is 120 mm, the height is 55 mm, the edge thickness is 20 mm, and the steel plate thickness is 2 mm.

[0127] The open cross-section design of C-shaped steel makes its load-bearing capacity stronger, while effectively reducing its own weight, facilitating transportation and installation; C-shaped steel has higher strength, good plasticity and toughness, and can effectively resist the invasion of natural disasters such as earthquakes and typhoons; the size and shape of C-shaped steel are designed and produced according to standards, which makes them more convenient to install during the installation process, without the need for complex on-site processing, thus reducing the installation time and cost; the finished C-shaped steel has good bending compressibility, automatic cutting, automatic punching, high automation, and quick and convenient installation; C-shaped steel has the advantages of light weight, high strength, good mechanical properties, and excellent seismic performance, with fast construction speed, beautiful appearance, and recyclability, meeting the sustainable development policy.

[0128] L100*63*6 indicates that the long side of the angle steel is 100mm, the short side is 63mm, and the thickness is 6mm;

[0129] Angle steel has high compressive strength and bending stiffness, can bear large forces.

[0130] The M12*50 bolt means the bolt diameter is 12 millimeters, and 50 refers to the rod length of 50 millimeters; the M8*22 bolt means the bolt diameter is 8 millimeters, and 22 refers to the rod length of 22 millimeters.

[0131] In an optional embodiment of the present invention, the first bolt hole 613 and the second bolt hole 623 are set according to a first preset value;

[0134] The third bolt hole 624 and the fourth bolt hole 625 are both oval holes, with a major axis of 30mm and a minor axis of 16mm. The above aperture values can meet the actual needs on site, and the aperture values can also be adjusted according to actual needs.

[0135] In the traditional bolt round hole structure, due to the shape of the round hole, it is difficult for the axial force to spread smoothly, which will cause bolt stress concentration and fracture; while the eccentric distance of the bolt oval hole is larger, which can make the stress distribution more even and reduce the risk of stress concentration and fracture;

[0136] The shape of the bolt oval hole also helps to increase the torsional angle of the bolt, enabling it to rotate freely, thus achieving a better fastening effect;

[0137] The design of the elliptical holes of the bolts can also save some construction processes. For traditional round-hole bolts, positioning and adjustment are required before installation, but the elliptical holes can make the bolts rotate to the correct position by themselves, reducing the adjustment process.

[0138] In an alternative embodiment of the present utility model, the fifth bolt hole 71 and the sixth bolt hole 72 are set according to a third preset value;

[0139] The seventh bolt hole 81 and the eighth bolt hole 82 are set according to a third preset value;

[0142] The seventh bolt hole 81 and the eighth bolt hole 82 both have a diameter of 16 mm.

[0143] The ninth bolt hole 31 and the tenth bolt hole 32 are both elliptical holes with a major axis of 25 mm and a minor axis of 16 mm. The above aperture values can meet the actual on-site needs, and the aperture values can also be adjusted according to actual needs.
