For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0035] The embodiment of the present application provides a bidirectional seismic support and hanger for a wind turbine. Figures 1 to 4 The wind turbine bidirectional anti-seismic support and hanger comprises a hanger 100, an anti-seismic connector 200, at least one first support arm 300 and at least one second support arm 400.

[0036] The top of the hanger 100 is connected to the building roof 900, forming an installation space for the fan 800 between the hanger 100 and the building roof 900. The bottom of the hanger 100 is used to install the fan 800. At least one first support arm 300 is connected to the hanger 100 at one end via a seismic connector 200, and at the other end of the at least one first support arm 300 is connected to the building roof 900 via a seismic connector 200. Furthermore, the at least one first support arm 300 is arranged obliquely in a plane perpendicular to a first direction 1000a. At least one second support arm 400 is connected to the hanger 100 at one end via a seismic connector 200, and at the other end of the at least one second support arm 400 is connected to the building roof 900 via a seismic connector 200. Furthermore, the at least one second support arm 400 is arranged obliquely in a plane perpendicular to a second direction 1000b. The first direction is perpendicular to the second direction 1000b.

[0037] When the bidirectional seismic support hanger of the wind turbine encounters an earthquake, the hanger 100 on which the wind turbine 800 is installed vibrates. The seismic connectors 200 set at both ends of the first support arm 300 can buffer the swing of the hanger 100 perpendicular to the first direction 1000a, and the seismic connectors 200 set at both ends of the second support arm 400 can buffer the swing of the hanger 100 perpendicular to the second direction 1000b. Since the first direction 1000a is perpendicular to the second direction 1000b, the swing of the hanger 100 in all directions can be buffered to reduce the vibration amplitude of the wind turbine 800 and the hanger 100, prevent structural damage to the wind turbine 800 body and pipeline rupture, and ensure personnel safety and production operation.

[0038] Reference Figures 1 to 3 As shown, in some embodiments of the present application, the hanger 100 includes two longitudinal beams 120, two transverse beams 110, and four columns 130. The two longitudinal beams 120 are arranged in parallel. The two transverse beams 110 are arranged in parallel and located between the two longitudinal beams 120, with each transverse beam 110 having two ends connected to the two longitudinal beams 120. The bottom ends of the four columns 130 are respectively connected to the ends of the two longitudinal beams 120, and the top ends of the four columns 130 are connected to the building roof 900. The end of at least one first support arm 300 is connected to the four columns 130, and the end of at least one second support arm 400 is connected to the two longitudinal beams 120.

[0039] The two longitudinal beams 120 and the two transverse beams 110 are located below the building roof 900 and are connected to the building roof 900 via four columns 130, thereby forming an installation space surrounded by the two longitudinal beams 120, the two transverse beams 110, the four columns 130, and the building roof 900. The fan 800 is located in the installation space and can be fixedly mounted on the two longitudinal beams 120 and / or the two transverse beams 110. For example, Figure 1 The fan 800 shown is fixedly mounted on two longitudinal beams 120 .

[0040] Reference Figure 1 and Figure 2 At least one first arm 300 includes four first arms 300 , one end of the four first arms 300 is connected to the four columns 130 through the seismic connector 200 , and the other end of the four first arms 300 is inclined upward and away from the column 130 .

[0041] by Figure 1 The illustrated position is used as an example to illustrate the position and connection relationship of the four first arms 300 . Figure 1 The right ends of the two first arms 300 on the left side of the hanger 100 are respectively connected to the two columns 130 on the left side, and the left ends of the two first arms 300 on the left side of the hanger 100 are inclined upward in a direction away from the columns 130; Figure 1 The left ends of the two first arms 300 on the right side of the hanger 100 are respectively connected to the two columns 130 on the right side, and the right ends of the two first arms 300 on the right side of the hanger 100 are inclined upward in a direction away from the columns 130.

[0042] The seismic connectors 200 at both ends of each first arm 300 are used to cushion the swing of the corresponding column 130 perpendicular to the first direction 1000a, so that the hanger 100 will not cause damage to the fan 800 due to excessive swing amplitude or excessive swing speed perpendicular to the first direction 1000a.

[0043] Reference Figure 3 In other embodiments of the present application, the hanger 100 further includes two reinforcing rods 140. The two reinforcing rods 140 are parallel to the two crossbeams 110, and the two ends of each reinforcing rod 140 are respectively connected to the two columns 130. The at least one first support arm 300 includes two first support arms 300, one end of each first support arm 300 is respectively connected to the two reinforcing rods 140, and the other end of each first support arm 300 is inclined upward and away from the column 130.

[0044] The two reinforcing rods 140 can strengthen the overall rigidity of the hanger 100, so that the hanger 100 is not prone to large deformation during vibration, thereby reducing the vibration amplitude of the fan 800 on the hanger 100 and reducing the possibility of damage to the fan 800.

[0045] Compared with the structural form in which four first arms 300 are respectively connected to four columns 130, two first arms 300 are respectively connected to two reinforcing rods 140, which not only increases the overall rigidity of the hanger 100, but also reduces the number of first arms 300, thereby reducing the number of connection points with the building roof 900, facilitating the rapid connection of the wind turbine's bidirectional seismic support hanger on the building roof 900.

[0046] The at least one second support arm 400 includes two second support arms 400 , one end of the two second support arms 400 is connected to one of the longitudinal beams 120 , and the other ends of the two second support arms 400 are inclined upward and away from the longitudinal beam 120 .

[0047] For example, Figure 2 and Figure 3 As shown, one end of the two second arms 400 is connected to a longitudinal beam 120 at the rear end of the fan 800. Figure 2 and Figure 3 Taking the shown orientation as an example, the left ends of the two second arms 400 are connected to a longitudinal beam 120 located at the rear end of the fan 800 , and the right ends of the two second arms 400 are inclined upward in a direction away from the longitudinal beam 120 .

[0048] Of course, one end of the two second arms 400 may also be connected to a longitudinal beam 120 located at the front end of the fan 800 .

[0049] like Figure 2 and Figure 3 As shown, the wind turbine bidirectional anti-seismic support and hanger further includes two tension springs 500 , and the two ends of the two tension springs 500 are respectively connected to the middle parts of the two second support arms 400 and another longitudinal beam 120 .

[0050] For example, Figure 2 and Figure 3 As shown, one end of the two second arms 400 is connected to a longitudinal beam 120 located at the rear end of the fan 800, one end of the tension spring 500 is connected to the middle of the second arm 400, and the other end of the tension spring 500 is connected to a longitudinal beam 120 located at the front end of the fan 800.

[0051] Specifically, hook bolts are installed on the middle portion of the second arm 400 and the longitudinal beam 120 for installing the tension spring 500 , and both ends of the tension spring 500 are hung on the hook bolts.

[0052] The two tension springs 500 connect the longitudinal beams 120 that are not connected to the second support arm 400 through the anti-seismic connector 200 to the second support arm 400, so that both longitudinal beams 120 are connected to the building top surface 900 through the second support arm 400. Figure 2 and Figure 3 Taking the illustrated position as an example, when the hanger 100 moves to the lower left, the tension spring 500 can buffer the hanger 100 .

[0053] In some embodiments of the present application, Figure 1 As shown, the wind turbine bidirectional anti-seismic support hanger further includes a plurality of spring shock absorbers 600 , which are arranged at the bottom of the hanger 100 for supporting the wind turbine 800 and cushioning the wind turbine 800 when it moves downward relative to the hanger 100 .

[0054] The fan 800 moves downward relative to the hanger 100, including: the fan 800 moves downward relative to the hanger and the fan 800 does not move in other directions, and the movement direction of the fan 800 has a vertical downward component relative to the hanger 100. For example, Figure 1 The wind turbine bidirectional anti-seismic support bracket shown includes four spring shock absorbers 600, and the four spring shock absorbers 600 are arranged in a rectangular shape.

[0055] When the fan 800 moves downward relative to the hanger 100 , the fan 800 squeezes the multiple spring shock absorbers 600 . The multiple spring shock absorbers 600 are compressed to cushion the fan 800 , thereby preventing the fan 800 from being damaged during the swinging process.

[0056] Reference Figures 1 to 3 In this embodiment, the bidirectional seismic support bracket of the fan also includes a top shock-absorbing assembly 700, which is connected to the bracket 100 and is configured to press the top surface of the fan 800 and cushion the fan 800 when it moves upward relative to the bracket 100.

[0057] The upward movement of the fan 800 relative to the hanger 100 includes: the fan 800 moves upward relative to the hanger and the fan 800 does not move in other directions, and the moving direction of the fan 800 has a vertical upward component relative to the hanger 100 .

[0058] When fan 800 moves upward relative to hanger 100, fan 800 compresses the shock-absorbing assembly, which in turn compresses and cushions fan 800, preventing damage during its swing. Furthermore, the shock-absorbing assembly and spring damper 600 work together to cushion the vertical movement of fan 800.

[0059] Specifically, continue to refer to Figure 1 The top shock-absorbing assembly 700 includes a connection base 710, multiple connection arms 720, and a soft elastic layer 730. The connection base 710 is located in the installation space. One end of the multiple connection arms 720 is connected to the connection base 710 via anti-vibration connectors 200 at intervals, and the other ends of the multiple connection arms 720 are connected to the hanger 100 via anti-vibration connectors 200. The soft elastic layer 730 is provided on the bottom surface of the connection base 710 and is configured to compress the fan 800.

[0060] Exemplarily, the soft elastic layer 730 may be a rubber layer.

[0061] When fan 800 is installed on the fan bidirectional seismic support and hanger, soft elastic layer 730 is located above fan 800, and connecting seat 710 presses soft elastic layer 730 against the outer circumference of fan 800. When fan 800 moves upward relative to hanger 100, fan 800 presses soft elastic layer 730, which in turn provides cushioning for fan 800.

[0062] Specifically, if Figures 1 to 3 As shown, in some embodiments of the present application, the first arm 300 is a viscous damper.

[0063] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0064] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
