Various loads and rain erosion for a long time can easily cause the brackets or foundations to twist and deform, and there are great safety hazards in production. Because the cross-sectional size of the columns is small and the bending resistance is insufficient, the brackets and connectors are not firm, and a large number of bolts and diagonal rods are loose in the photovoltaic field. The looseness and lack of bolts and diagonal rods will cause the brackets to move too much under the action of wind loads, and the photovoltaic field has long had the phenomenon of unqualified bolt tightening torque. In order to improve the safe and stable operation of photovoltaic power stations, ensure the safe supply of electricity for large-scale photovoltaic power stations in national bases, maintain the national power energy supply, reduce the cost of operation and maintenance, and increase the power generation of photovoltaic strings, the wind disaster prevention reinforcement structure and installation process of photovoltaic power stations in high altitude areas are designed.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figures 1-2 , is the first embodiment of the present invention, which provides a fixing mechanism for disaster prevention of photovoltaic strings in high-altitude areas, which includes a support unit 100, including a load-bearing beam 101, a first pillar 102 arranged to connect the load-bearing beam 101 with the ground, a support rod 103 is arranged between the first pillar 102 and the load-bearing beam 101, and a connecting piece 104 is arranged at the connection between the first pillar 102 and the load-bearing beam 101; a fixing unit 200, including a pull rope 201, one end of the pull rope 201 is fixedly connected to the outer wall of the load-bearing beam 101, one end of the pull rope 201 is connected to the outer wall of a fixing seat 202, the fixing seat 202 is fixed to the ground, the load-bearing beam 101 is connected to a second pillar 203, and the second pillar 203 is connected to the ground.

[0028] The load-bearing beam 101 is a straight beam, and in actual use, a steel material with a thick wall is often used. The first pillar 102 is the core support of the entire mechanism. The first pillar 102 is a round tube type with high bending resistance. The first pillar 102 can be directly inserted into the ground or inserted into a large mass solid building material such as a cement block. The load-bearing beam 101 is connected to the end of the first pillar 102 away from the ground. The connection method can be a direct connection such as welding, or an intermediate connection piece is used to connect the load-bearing beam 101 and the first pillar 102. This solution adopts a connection piece 104 to fill the load-bearing beam 101 and the first pillar 102. When the connecting medium, the connecting piece 104 is bolted to the load-bearing beam 101 and the first pillar 102, which increases the strength of the component, reduces the number of nodes, and improves the overall stability. The support rod 103 has a certain inclination when connecting the first pillar 102 and the load-bearing beam 101; the fixed seat 202 is made of cross steel bars and stainless steel connected with concrete, and the two ends of the pull rope 201 are respectively fixed to the fixed seat 202 and the load-bearing beam 101, which increases the overall stability. The two ends of the second pillar 203 are respectively fixed to the load-bearing beam 101 and the ground, which further increases the stability of the overall structure.

[0029] When in use, one end of the first pillar 102 is fixed to the ground, and the other end of the first pillar 102 is fixedly connected to the connecting piece 104, the part of the connecting piece 104 not connected to the first pillar 102 is connected to the load-bearing beam 101, and the two ends of the support rod 103 are fixedly connected to the load-bearing beam 101 and the outer wall of the first pillar 102 by bolts, and the two ends of the pull rope 201 are respectively fixedly connected to the load-bearing beam 101 and the outer wall of the fixing seat 202, and the two ends of the second pillar 203 are respectively fixed to the load-bearing beam 101 and the outer wall of the ground.

[0030] In summary, with the pull rope 201 being fixed by the fixing seat 202 to pull the load-bearing beam 101 and the second pillar 203 providing auxiliary tension, the tension of the photovoltaic panel under wind load is dispersed, and the load-bearing beam 101 is not easily deformed due to the photovoltaic panel being affected by wind and rain, thereby increasing the overall stability.

[0031] Example 2

[0032] Reference Figures 1-2 , which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes a crossbeam 105 fixedly connected to the surface of the side of the load-bearing beam 101 away from the first pillar 102, and the crossbeam 105 is provided with a photovoltaic panel 106 on the outer wall of the side of the load-bearing beam 101 away from the first pillar 102.

[0033] Among them, the crossbeam 105 is fixed to the outer wall of the load-bearing beam 101 by bolts. There are multiple holes on the outer wall of the crossbeam 105 for bolts to pass through to achieve bolt fit. It should be noted that in actual use, holes can be drilled on the surface of the photovoltaic panel 106. Therefore, the crossbeam 105 is bolted to the photovoltaic panel 106 on the surface that is not connected to the load-bearing beam 101. The bolt connection between the crossbeam 105 and the load-bearing beam 101 can be direct connection or intermediate medium connection.

[0034] Furthermore, a pressure piece 106 a is provided at the edge of the photovoltaic panel 106 . The pressure piece 106 a can wrap a portion of the edge of the photovoltaic panel 106 . One end of the pressure piece 106 a is fixedly connected to the crossbeam 105 .

[0035] Among them, the pressure piece 106a is composed of two pressure plates and an intermediate connection. The intermediate connection part of the pressure piece 106a is selected to be a bolt connection that can adjust the relative distance between the two pressure plates. The side of the two pressure plates close to the other pressure plate is respectively in contact and pressed with the side of the photovoltaic panel close to the ground and the side away from the ground. The fixed connection method of the pressure piece 106a and the beam 105 can be selected from welding, bolt connection, etc. For the convenience of maintenance and replacement, bolt connection is selected in this solution.

[0036] Furthermore, the load-bearing beam 101 has a certain angle with the ground.

[0037] The angle between the load-bearing beam 101 and the ground is taken from the local latitude angle. It should be noted that the source of this data is taken from the national standard GB50797-2012 "Design Specifications for Photovoltaic Power Stations".

[0038] Furthermore, the pull rope 201 is a stainless steel wire.

[0039] Among them, when the material of the pull rope 201 is stainless steel wire, in a high-altitude environment, steel materials are more susceptible to rust than in a low-altitude environment, so stainless steel wire is selected.

[0040] Furthermore, a first elastic member 202a is provided on the outer wall of the connection between the pull rope 201 and the fixing seat 202 .

[0041] Among them, when the pull rope 201 is used to connect the fixing seat 202 and the load-bearing beam 101, the photovoltaic panel 106 will shake due to the influence of wind and rain in the environment, thereby affecting the shaking of the load-bearing beam 101. When the first elastic member 202a is added, the shaking of the photovoltaic panel 106 can be reduced by transmitting its own deformation through the pull rope 201. It should be noted that the first elastic member 202a can be made of any elastic material such as a spring, rubber, etc.

[0042] Furthermore, a plurality of support rods 103 are provided between the first support column 102 and the load-bearing beam 101 .

[0043] In particular, when a plurality of support rods 103 are provided, more supporting force can be provided to the load-bearing beam 101 compared with a single support rod 103 .

[0044] Furthermore, a plurality of the pull ropes 201 are provided between the load-bearing beam 101 and the ground, and the number of the fixing seats 202 is the same as the pull ropes 201 .

[0045] Among them, when there are multiple pull ropes 201, compared with the case of a single pull rope 201, a stronger back-pulling effect will be provided for the load-bearing beam 101. The number of fixing seats 202 is consistent with the pull ropes 201, and each fixing seat 202 is only connected to one pull rope 201.

[0046] Furthermore, an intermediate connecting piece 103a is provided at the connection between the support rod 103 and the first pillar 102, a base 203a is provided between the second pillar 203 and the ground, the base 203a is fixedly connected to the ground, and the second pillar 203 is fixedly connected to the base 203a.

[0047] Among them, when the support rod 103 is directly connected to the surface of the first pillar 102, it is necessary to drill a hole on the surface of the first pillar 102 or directly weld the support rod 103 to the surface of the first pillar 102, which will affect the strength of the first pillar 102 itself and is not convenient for subsequent maintenance and replacement. An intermediate connecting piece 103a is fixedly connected to the outer wall of the first pillar 102. In this solution, the intermediate connecting piece 103a is fixedly connected to the outer wall of the first pillar 102 by welding, and the intermediate connecting piece 103a is connected to the support rod 103 by bolting; the base 203a is actually a hole of suitable size drilled in the ground, and an iron pipe with a steel structure is placed in it. It should be noted that the inner diameter of the iron pipe is sufficient to accommodate the second pillar 203. After the second pillar 203 is inserted into the iron pipe of the base 203a, it can be fixed by welding, bolting, etc. This solution uses bolting to facilitate subsequent replacement of parts and maintenance.

[0048] When in use, one end of the first pillar 102 is fixed to the ground, and the other end of the first pillar 102 is fixedly connected to the connecting piece 104, and the part of the connecting piece 104 not connected to the first pillar 102 is connected to the load-bearing beam 101, and the outer wall of the first pillar 102 is welded with an intermediate connecting piece 103a, and the two ends of the support rod 103 are fixedly connected to the intermediate connecting piece 103a of the outer wall of the load-bearing beam 101 and the outer wall of the first pillar 102 by bolts, and the two ends of the pull rope 201 are respectively fixedly connected to the first connecting piece 103a of the outer wall of the load-bearing beam 101 and the fixing seat 202. On the elastic member 202a, a hole is drilled in the ground to accommodate the base 203a, and the base 203a is placed in the hole. One end of the second pillar 203 is bolted to the outer wall of the load-bearing beam 101, and the other end of the second pillar 203 not connected to the load-bearing beam 101 is bolted to the base 203a. The side of the load-bearing beam 101 away from the ground is bolted to the cross beam 105, and the side of the cross beam 105 away from the ground is bolted to the pressure member 106a. The pressure member 106a wraps part of the edge of the photovoltaic panel 106 and is fixed with bolts.

[0049] In summary, with the pull rope 201 being fixed by the fixing seat 202 to pull the load-bearing beam 101 and the second pillar 203 providing auxiliary tension, the tension of the photovoltaic panel under wind load is dispersed, and the load-bearing beam 101 is not easily deformed due to the photovoltaic panel being affected by wind and rain, thereby increasing the overall stability.

[0050] Example 3

[0051] Reference Figures 1 to 3, which is the third embodiment of the present invention, which is different from the previous two embodiments in that this embodiment further provides an installation process for a fixing mechanism for disaster prevention of photovoltaic strings in high altitude areas: comprising a fixing mechanism for disaster prevention of photovoltaic strings in high altitude areas, and one end of a first pillar 102 is fixedly installed and inserted into the ground, a connecting piece 104 is installed at an end of the first pillar 102 away from the ground by bolts, an end of the connecting piece 104 away from the connection with the first pillar 102 is installed with a load-bearing beam 101 by bolts, an intermediate connecting piece 103a is welded to a portion of the first pillar 102 above the ground, two ends of the support rod 103 are respectively bolted to the intermediate connecting piece 103a and the load-bearing beam 101, and a cross beam 105 is bolted It is installed on the side of the load-bearing beam 101 away from the ground, the pressure piece 106a is bolted to the crossbeam 105, the pressure piece 106a is fixedly connected to the edge bolts of the photovoltaic panel 106, wire clamps are provided at both ends of the load-bearing beam 101 and at the connection between the fixing seat 202 and the pull rope 201, a first elastic piece 202a is fixedly provided between the wire clamp on the fixing seat 202 and the fixing seat 202, the pull rope 201 is fixed by the load-bearing beam 101 and the wire clamp on the fixing seat 202, a hole is first drilled in the ground to accommodate the base 203a, the base 203a is placed in the drilled hole and fixed, one end of the second pillar 203 is bolted to the outer wall of the load-bearing beam 101, and the other end of the second pillar 203 not connected to the load-bearing beam 101 is bolted to the base 203a.

[0052] Among them, the installation process will not be able to achieve the installation of the fixing mechanism if it does not comply with the installation sequence. Therefore, it is necessary to install according to the installation process. One end of the first pillar 102 can be encapsulated with fine stone concrete or cement grouting to increase the stability of the first pillar 102. The sizes of the connecting piece 104 and the pull rope 201 vary according to the installation area. The base 203a is placed in the drilled hole and concrete can be poured to increase the stability of the base 203a. All bolts connected by bolts must be tightened. If there are burrs or concrete on the surface of the screw that make the nut unable to be tightened, the bolts are reinforced by welding to the base plate, and the welding parts are treated with rust prevention. At the end of the installation, all bolts must be re-tightened.

[0053] When in use, after the first pillar 102 is fixed on the ground, it is necessary to pay attention to the angle between the load-bearing beam 101 and the ground when installing the load-bearing beam 101. After determining the angle between the load-bearing beam 101 and the ground, other components can be installed. After installation, it is necessary to re-tighten to confirm the tightness of the installation bolts.

[0054] In summary, under the present installation process, the fixing mechanism used for disaster prevention of photovoltaic strings in high altitude areas can disperse the tension of the photovoltaic panels when they are subjected to wind loads, with the pull rope 201 being fixed by the fixing seat 202 to pull the load-bearing beam 101 and the second pillar 203 providing auxiliary tension. The load-bearing beam 101 is not easily deformed by the photovoltaic panels being affected by wind and rain, thus preventing the photovoltaic strings from deforming and collapsing, and increasing the overall stability.
