[0047] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0048] Figures 1-5 This diagram illustrates the structure of a fan noise reduction device 100 according to an embodiment of this application. Figures 1-5 As shown, the noise reduction device 100 may include:

[0049] The support frame 110 has its bottom set in the concrete ground, and the fan is located between the four supporting legs of the support frame 110.

[0050] Several sound insulation panels 120 are detachably mounted on the bracket 110. When the sound insulation panels 120 are mounted on the bracket 110, the fan is located inside the bracket 110.

[0051] A plurality of mounting components 130 are respectively mounted on a plurality of sound insulation panels 120, and the sound insulation panels 120 are detachably connected to the bracket 110 through the mounting components 130.

[0052] In this embodiment, the bracket 110 is rooted in the cement ground where the wind turbine is located and is firmly connected to the ground by the anchor steel plate and chemical anchors. The bracket 110 is made of hot-dip galvanized steel to enhance its service life. The welds are fully welded to ensure safety and stability. The bracket 110 is rectangular. The sound insulation panel 120 is quickly installed on the bracket 110 by the installation component 130. The installation component 130 facilitates the rapid splicing of the sound insulation panel 120. At the same time, the sound insulation panels 120 can be spliced ​​together. When installing the sound insulation panel 120 on the bracket 110, the sound insulation panel 120 at one end of the bracket 110 is pre-installed. The sound insulation panels 120 are installed sequentially from one end to the other end. Finally, the sound insulation panel 120 on the other end of the bracket 110 is installed to complete the installation of the top sound insulation panel 120 of the bracket 110. The sound insulation panels 120 on the side of the bracket 110 are installed with reference to the top sound insulation panel 120.

[0053] The sound insulation panels 120 are installed sequentially along the bracket 110. The mounting component 130 facilitates the quick fastening of the sound insulation panels 120 and the bracket 110, making it easy to install the sound insulation panels 120 and fix them quickly. Compared with the traditional installation by screws or welding, it saves more time and is easier to install and disassemble, thus improving the installation efficiency of the sound insulation panels 120.

[0054] Furthermore, the sound insulation panel 120 uses BJYG100 composite sound-absorbing and sound-insulating panel.

[0055] like Figure 5 As shown, in one embodiment,

[0056] The cross-section of the bracket 110 is T-shaped.

[0057] In this embodiment, the cross-section of the bracket 110 is a T-shape arranged laterally. When the sound insulation panel 120 is installed on the top of the bracket 110, the bracket 110 provides a certain support for the sound insulation panel 120 on the side and top, ensuring the stability of the sound insulation panel 120 installation.

[0058] Furthermore, the horizontal and vertical bars of the bracket 110 are provided with insertion holes 111 to facilitate the installation of the sound insulation panels 120 on the top and sides of the bracket 110.

[0059] like Figures 1-2 As shown, in one embodiment,

[0060] Both sound insulation panels 120 located at both ends have protrusions 121, and the protrusions 121 are arranged in a staggered manner.

[0061] Each of the sound insulation panels 120 located between the two ends has two protrusions 121, and the two protrusions 121 are staggered. When the sound insulation panels 120 are spliced ​​together, the protrusions 121 between adjacent sound insulation panels 120 are in contact.

[0062] In this embodiment, the sound insulation plates 120 installed at both ends of the bracket 110 each have a protrusion 121, wherein the side of the sound insulation plate 120 at one end is stepped, and the side of the sound insulation plate 120 at the other end is an inverted stepped structure.

[0063] Each of the sound insulation panels 120 located between the two end sound insulation panels 120 has two protrusions 121. The two protrusions 121 are respectively located at both ends of the middle sound insulation panel 120, and one side of the protrusion 121 forms a stepped structure with the middle sound insulation panel 120, while the other side of the protrusion 121 forms an inverted stepped structure with the middle sound insulation panel 120.

[0064] During the splicing process, the stepped sound insulation panel 120 on the side is pre-installed at one end of the bracket 110, and the middle sound insulation panel 120 is installed sequentially at the other end of the bracket 110. At this time, the two sides of the sound insulation panel 120 are spliced ​​with the protrusions 121 of the adjacent sound insulation panel 120. After the splicing is completed, the sound insulation panel 120 at the other end is installed at the other end of the bracket 110, so that the inverted stepped structure on the sound insulation panel 120 at the other end fits with the protrusions 121 on the middle sound insulation panel 120.

[0065] like Figures 1-4 As shown, in one embodiment,

[0066] The sound insulation panel 120 has a plurality of grooves 122, and the mounting assembly 130 is disposed in the grooves 122. The plurality of grooves 122 are respectively disposed at both ends and one side of the sound insulation panel 120, and an insertion hole 111 is provided on the side of the sound insulation panel 120 away from the grooves 122.

[0067] In this embodiment, the sound insulation panel 120 has grooves 122 at both ends and on the sides, and each groove 122 is provided with an installation component 130. The sound insulation panel 120 is connected to the bracket 110 through the installation components 130 at both ends, and the sound insulation panel 120 is spliced ​​with the adjacent sound insulation panel 120 through the installation components 130 on the sides and the insertion holes 111.

[0068] like Figures 1-4 As shown, in one embodiment,

[0069] The mounting component 130 includes:

[0070] A fixing rod 131 is disposed on the sound insulation plate 120 and is located within the groove 122;

[0071] A movable rod 132 is sleeved on the fixed rod 131, and the movable rod 132 moves along the fixed rod 131;

[0072] Limiting block 133, the limiting block 133 is disposed on the movable rod 132;

[0073] Spring 134 is sleeved on the fixed rod 131 and the movable rod 132. One end of spring 134 is connected to the limiting block 133 and the other end is connected to the groove 122.

[0074] In this embodiment, the movable rod 132 moves along the fixed rod 131. When the movable rod 132 moves, the limiting rod and the groove 122 compress the spring 134, causing the spring 134 to deform. When the sound insulation plate 120 is installed on the bracket 110, the movable rod 132 moves along the fixed rod 131 into the groove 122 under the action of the bracket 110, causing the limiting block 133 to compress the spring 134. When the movable rod 132 moves to the position of the insertion hole 111 on the bracket 110, the spring 134 returns to its original position, thereby allowing the movable rod 132 to enter the insertion hole 111, locking the position of the sound insulation plate 120 and the bracket 110.

[0075] Furthermore, the bracket 110 is provided with a socket 111 that is adapted to the movable rod 132, and the diameter of the movable rod 132 matches the diameter of the socket 111.

[0076] When the sound insulation panel 120 needs to be removed, simply push the movable rod 132 in the through hole out of the socket 111 from the other side of the bracket 110.

[0077] When installing the middle soundproofing panel 120, simply insert the movable rod 132 on the side of the soundproofing panel 120 into the insertion hole 111 on the side of the adjacent soundproofing panel 120. When disassembling, simply remove the soundproofing panel 120 at one end, and then push the movable rod 132 on both ends of the middle soundproofing panel 120 and the bracket 110 out of the insertion hole 111.

[0078] Furthermore, the top of the movable rod 132 has an arc-shaped structure. When the sound insulation plate 120 contacts the bracket 110, the movable rod 132 moves along the fixed rod 131 into the groove 122 under the action of the arc-shaped structure at the top.

[0079] like Figure 1 As shown, in one embodiment,

[0080] An inspection door 140 is provided on one of the sound insulation panels 120 on the side of the bracket 110.

[0081] In this embodiment, the inspection door 140 is a high sound insulation metal door with a door panel size of 1900*1000, which can meet the needs of daily inspection and access while also taking into account the sound insulation effect.

[0082] like Figure 1 As shown, in one embodiment,

[0083] A ventilation assembly 150 is provided on one of the sound insulation panels 120 on the side of the bracket 110.

[0084] In this embodiment, the ventilation assembly 150 includes a fan, and the fan is equipped with a silencer, which uses a resistive plate silencer structure.

[0085] The functions of each module in each device of this utility model embodiment can be found in the corresponding description in the above method, and will not be repeated here.

[0086] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this application, and these should all be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
