Description

Technical Field

[0001] The present application relates to the technical field of wind power generation, and in particular to a fire retardant device and a wind power generator set. Background Art

[0002] Wind energy is a clean, pollution-free, renewable energy source. Unlike fossil fuels, wind energy is inexhaustible, and its primary use is in wind power generation. Because wind power generation does not produce carbon dioxide or other harmful gases, its environmental impact is minimal. Furthermore, with technological advancements and scale-up, the cost of wind power generation is gradually decreasing, making it highly competitive with traditional energy sources such as coal and natural gas.

[0003] In practical applications, wind power generation requires the use of wind turbines. Wind turbines are systems that convert wind kinetic energy into electrical energy. They typically consist of a tower and a generator with a rotor. Cables are laid within the tower, connecting the tower base to the generator nacelle. Because the tower is divided into multiple sections, traditional wind turbines typically have a platform within each section. Each platform within each section has a clearance notch on its edge. This clearance notch, in conjunction with the tower wall, forms a threading hole for laying cables.

[0004] During the service of wind turbines, there is a risk of cable fires, wherein cable fires are usually caused by the ends of the cables or the joints of the cables. Once a fire occurs, the fire will spread along the laid cables, causing great losses. For this reason, the relevant technology proposes to set a fire-retardant device at the threading port on the platform inside each section of the tower of the wind turbine. In the event of a fire, it can prevent the fire from spreading along the laid cables, so that the entire cable will not be damaged. However, the structure of the traditional fire-retardant device is relatively complex and difficult to implement. In addition, the traditional fire-retardant device needs to be implemented during the construction of the wind turbine. For old wind turbines that have been completed and put into use, since the threading port on the platform inside the tower has already been threaded with cables, the traditional fire-retardant device is not applicable. Utility Model Content

[0005] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a fire retardant device that is not only simple in structure and easy to implement, but also applicable to old wind turbines that have been completed and put into use.

After the cable is threaded, fireproof mud is laid on the first tray and the second tray and the area where the cable is threaded is covered. Its structure is simple and easy to implement. In addition, for old wind turbine generator sets that have been completed and put into use, since the threading port on the platform inside the tower of the wind turbine generator set has been threaded with a cable, when implemented, the first tray is hung at the threading port and the first tray is located on one side of the cable, and then the second tray is hung at the threading port and the second tray is located on the other side of the cable, and finally fireproof mud is laid on the first tray and the second tray and the area where the cable is threaded is covered.

[0030] Wind energy is a clean, pollution-free, renewable energy source. Unlike fossil fuels, wind energy is inexhaustible, and its primary use is in wind power generation. Since wind power generation does not produce carbon dioxide or other harmful gases, its environmental impact is minimal. Furthermore, with technological advancements and scale expansion, the cost of wind power generation is gradually decreasing, making it highly competitive compared to traditional energy sources such as coal or natural gas.

[0031] In practical applications, wind power generation requires the use of wind turbines. Wind turbines are systems that convert wind kinetic energy into electrical energy. They typically consist of a tower and a generator with a rotor. Cables are laid within the tower, connecting the tower base to the generator nacelle. Because the tower is divided into multiple sections, traditional wind turbines typically have a platform within each section. Each platform within each section has a clearance notch on its edge. This clearance notch, in conjunction with the tower wall, forms a threading hole for laying cables.

[0032] During the service of wind turbines, there is a risk of cable fires, wherein cable fires are usually caused by the ends of the cables or the cable joints. Once a fire occurs, the fire will spread along the laid cables, causing great losses. For this reason, the relevant technology proposes to set a fire-proof and flame-retardant device at the threading port on the platform inside each section of the tower of the wind turbine. In the event of a fire, it can prevent the fire from spreading along the laid cables, so that the entire cable will not be damaged. However, the structure of the traditional fire-proof and flame-retardant device is relatively complex and difficult to implement. In addition, the traditional fire-proof and flame-retardant device needs to be implemented during the construction of the wind turbine. For old wind turbines that have been completed and put into use, since the threading port on the platform inside the tower has already been threaded with cables, the traditional fire-proof and flame-retardant device is not applicable. For this reason, it is urgent to optimize the existing fire-proof and flame-retardant device to solve the above-mentioned technical problems. The optimized fire-proof and flame-retardant device of this application will be described in detail below with reference to the accompanying drawings.

[0033] Reference Figures 1 to 3 According to an embodiment of the present application, the fire-proof and flame-retardant device is used to be arranged at a wire threading opening c on a platform b inside a tower a of a wind turbine generator set, wherein the fire-proof and flame-retardant device includes a first tray 100 and a second tray 200.

[0034] Specifically, first hanging ears 110 for hanging at the edge of the threading port c are provided on opposite sides of the first pallet 100, so that the first pallet 100 can be hung at the threading port c, and second hanging ears 210 for hanging at the edge of the threading port c are provided on opposite sides of the second pallet 200, so that the second pallet 200 can be hung at the threading port c, wherein the first pallet 100 and the second pallet 200 are used to support fireproof mud.

[0035] During implementation, the first tray 100 and the second tray 200 are hung at the threading opening c on the platform b inside the tower a of the wind turbine generator set. The gap between the first tray 100 and the second tray 200 is used to thread the cables. After the cables are threaded, fireproof mud is laid on the first tray 100 and the second tray 200 and the area where the cables are threaded is covered. The structure is simple and easy to implement. In addition, for old wind turbine generator sets that have been completed and put into use, since cables have already been threaded at the threading opening c on the platform b inside the tower a, during implementation, the first tray 100 is hung at the threading opening c and the first tray 100 is positioned on one side of the cables. The second tray 200 is then hung at the threading opening c and the second tray 200 is positioned on the other side of the cables. Finally, fireproof mud is laid on the first tray 100 and the second tray 200 and the area where the cables are threaded is covered. The above-mentioned fire retardant device is not only simple in structure and easy to implement, but also applicable to old wind turbine generator sets that have been completed and put into use.

[0036] Reference Figures 1 to 3 In some embodiments, a first tray 100 is provided with a plurality of first protrusions 120 spaced apart on one side thereof for mating with the second tray 200. A first groove 130 for inserting a single cable is formed between two adjacent first protrusions 120. The first groove 130 is configured to cooperate with the second tray 200 to form a threading hole 300 for inserting a single cable. During use, multiple threading holes 300 for inserting a single cable are formed between the first tray 100 and the second tray 200, thereby separating the multiple cables from one another. This helps prevent the fire from spreading to other cables if one cable catches fire.

[0037] Reference Figure 2 and Figure 3 In some embodiments, a side of the second pallet 200 for cooperating with the first pallet 100 is provided with a plurality of second protrusions 220 corresponding one-to-one to the plurality of first protrusions 120, and the second protrusions 220 are used to support the corresponding first protrusions 120. When in use, the second protrusions 220 are located at the bottom of the corresponding first protrusions 120 to support the corresponding first protrusions 120, which is beneficial to improving the structural strength of the cooperation point between the first pallet 100 and the second pallet 200, so that the cooperation point between the first pallet 100 and the second pallet 200 can more stably support the fireproof mud.

[0038] Reference Figure 3 In some embodiments, a first buffer layer 140 is provided on one side of the first tray 100 for mating with the second tray 200. The first buffer layer 140 covers at least the wall of the first groove 130. The provision of the first buffer layer 140 helps prevent the cables running between the first tray 100 and the second tray 200 from being scratched.

[0039] It should be noted that, in some embodiments, the first buffer layer 140 is a rubber layer. Specifically, the rubber layer can be made of flame-retardant rubber.

[0040] It should be noted that, in some other embodiments, the first buffer layer 140 may also be a polyurethane foam layer, which is not limited here.

[0041] Reference Figure 3 In some embodiments, a second groove 230 for inserting a single cable is formed between two adjacent second protrusions 220. A second buffer layer 240 is provided on one side of the second tray 200 for mating with the first tray 100. The second buffer layer 240 at least covers the walls of the second groove 230. The provision of the second buffer layer 240 further prevents scratches on the cables inserted between the first tray 100 and the second tray 200.

[0042] It should be noted that, in some embodiments, the second buffer layer 240 is a rubber layer. Specifically, the rubber layer can be made of flame-retardant rubber.

[0043] It should be noted that, in some other embodiments, the second buffer layer 240 may also be a polyurethane foam layer, which is not limited here.

[0044] Reference Figures 1 to 3 In some embodiments, the second pallet 200 has an abutment surface 250 for cooperating with the inner wall of the tower a. The abutment surface 250 is arc-shaped so that the abutment surface 250 can better fit the inner wall of the tower a, so that the fireproof mud supported by the first pallet 100 and the second pallet 200 can more comprehensively cover the wire threading port c, which is beneficial to improving the fire retardant effect.

[0045] It should be noted that, in some embodiments, the first pallet 100 and the second pallet 200 are both made of metal, so that the first pallet 100 and the second pallet 200 not only have sufficient structural strength but also have fire retardant effects.

[0046] According to an embodiment of the present application, a wind turbine generator set includes the above-mentioned fire retardant device.

[0047] It can be understood that, since the wind turbine generator set of the embodiment of the present application includes the above-mentioned fire-proof and flame-retardant device, the wind turbine generator set of the embodiment of the present application has all the technical effects of the above-mentioned fire-proof and flame-retardant device.
