The bottom of the wall sound-absorbing and insulating panel is installed on a concrete foundation via a pre-embedded steel plate. H-shaped steel columns are installed on the inner side of the wall sound-absorbing and insulating panel, with their tops connected to the roof sound-absorbing and insulating panel via H-shaped steel beams. The bottom of the H-shaped steel columns is welded to the pre-embedded steel plate. This invention offers the following advantages: the roof sound-absorbing and insulating panel and the wall sound-absorbing and insulating panel are connected using a fully sealed slotted connection.

Description

Technical Field

[0001] This utility model relates to a noise reduction device for high-voltage parallel reactors in areas prone to strong typhoons. Background Technology

[0002] High-voltage parallel reactors are one of the main noise sources in substations. In order to cut off the propagation path of noise and reduce the impact of reactor noise on the surrounding environment, the reactors are usually covered with soundproof enclosures. The soundproof enclosures have sufficient sound absorption and sound insulation to prevent noise from spreading outward and reduce external noise to below the specified allowable value.

[0003] In addition to meeting sufficient strength requirements, the structure of the reactor soundproof enclosure must also consider ease of installation and disassembly, and meet the requirements for subsequent operation and maintenance of the reactor equipment.

[0004] The soundproof enclosure of a reactor typically utilizes the structural strength of the sound-absorbing and sound-insulating panels themselves, and uses bolts to connect and fix the main enclosure structure to the reactor. Figure 1 As shown, it includes a roof sound-absorbing and insulating panel 101, which is connected to a wall sound-absorbing and insulating panel 102 via an H-shaped steel top beam 103. The wall sound-absorbing and insulating panel 102 is connected to a concrete foundation 104 via an H-shaped steel top beam 103. A foundation embedded steel plate 105 is pre-embedded in the concrete foundation 104.

[0005] (1) The roof sound-absorbing and sound-insulating board 101 and the wall sound-absorbing and sound-insulating board 102 are connected to the fixed frame (H-shaped steel top beam 103) by bolts 106. Due to the limited strength of the bolt connection of the sound-absorbing and sound-insulating board, it will fall apart in areas with strong typhoons.

[0006] (2) At the connection between the sound-absorbing and sound-insulating board and the ground beam and top beam, the sound-absorbing and sound-insulating board cannot be fully covered, resulting in noise leakage. Utility Model Content

[0007] The technical problem to be solved by this utility model is: how to improve the noise reduction performance of shunt reactors and provide a noise reduction device for high-voltage shunt reactors in windy areas.

[0008] To solve the above problems, this utility model is achieved through the following technical solution:

[0009] A noise reduction device for high-voltage parallel reactors in typhoon-prone areas includes a roof sound-absorbing and insulating panel, with the ends of the roof sound-absorbing and insulating panel connected to a wall sound-absorbing and insulating panel. The bottom of the wall sound-absorbing and insulating panel is installed on a concrete foundation via a pre-embedded steel plate. An H-shaped steel column is installed on the inner side of the wall sound-absorbing and insulating panel, with the top of the H-shaped steel column connected to the roof sound-absorbing and insulating panel via an H-shaped steel top beam. The bottom of the H-shaped steel column is welded to the pre-embedded steel plate.

[0010] The wall-mounted sound-absorbing and sound-insulating panels are connected to the H-shaped steel columns by Z-shaped fixing clips.

[0011] A first C-shaped slot mounting plate is provided between the roof sound-absorbing and sound-insulating panel and the wall sound-absorbing and sound-insulating panel. One end of the first C-shaped slot mounting plate is inserted into the roof sound-absorbing and sound-insulating panel, and the other end of the first C-shaped slot mounting plate is inserted into the wall sound-absorbing and sound-insulating panel. Both ends of the first C-shaped slot mounting plate are provided with first edge-reducing fasteners.

[0012] A mounting steel plate is installed at the bottom of the roof sound-absorbing and sound-insulating panel. The wall sound-absorbing and sound-insulating panel is connected to the mounting steel plate by the first bolt, thereby realizing the direct connection between the wall sound-absorbing and sound-insulating panel and the roof sound-absorbing and sound-insulating panel. The H-shaped steel top beam is connected to the mounting steel plate by the second bolt, thereby realizing the connection between the H-shaped steel top beam and the roof sound-absorbing and sound-insulating panel.

[0013] A second C-shaped slot mounting plate is provided between the wall sound-absorbing and sound-insulating panel and the foundation embedded steel plate. One end of the second C-shaped slot mounting plate is stuck at the bottom of the foundation embedded steel plate, and the other end is stuck inside the wall sound-absorbing and sound-insulating panel. A second edge fixing component is provided at one end of the second C-shaped slot mounting plate located inside the wall sound-absorbing and sound-insulating panel.

[0014] Compared with the prior art, the present invention has the following advantages: the roof sound-absorbing and sound-insulating panels and the wall sound-absorbing and sound-insulating panels adopt a fully sealed slot connection. Compared with the conventional bolt connection method, the sound-absorbing and sound-insulating panels have a larger stress area under strong typhoons. Combined with the local snap-on fixing, the structural strength is greater and can withstand strong typhoons. Attached Figure Description

[0022] like Figure 2 As shown, a noise reduction device for a high-voltage parallel reactor in a strong typhoon area includes a roof sound-absorbing and insulating panel 1, with the ends of the roof sound-absorbing and insulating panel 1 connected to a wall sound-absorbing and insulating panel 2. The bottom of the wall sound-absorbing and insulating panel 2 is installed on a concrete foundation 4 via a foundation-embedded steel plate 3. An H-shaped steel column 5 is provided on the inner side of the wall sound-absorbing and insulating panel 2. The top of the H-shaped steel column 5 is connected to the roof sound-absorbing and insulating panel 1 via an H-shaped steel top beam 6. The bottom of the H-shaped steel column 5 is welded to the foundation-embedded steel plate 3.

[0023] Furthermore, the wall-mounted sound-absorbing and insulating panel 2 is connected to the H-shaped steel column 5 via Z-shaped fixing clips 7, resulting in a tighter and more stable connection. Figure 3 As shown.

[0024] like Figure 4 As shown, a first C-shaped slot mounting plate 10 is provided between the roof sound-absorbing and insulating board 1 and the wall sound-absorbing and insulating board 2. One end of the first C-shaped slot mounting plate 10 is inserted into the roof sound-absorbing and insulating board 1, and the other end of the first C-shaped slot mounting plate 10 is inserted into the wall sound-absorbing and insulating board 2. Both ends of the first C-shaped slot mounting plate 10 are provided with first edge-reducing fasteners 11.

[0025] Furthermore, a mounting steel plate 12 is provided at the bottom of the roof sound-absorbing and insulating panel 1, and the wall sound-absorbing and insulating panel 2 is connected to the mounting steel plate 12 by a first bolt 13, thereby achieving a direct connection between the wall sound-absorbing and insulating panel 2 and the roof sound-absorbing and insulating panel 1.

Here, the first bolt 13 is a T-bolt.

[0026] like Figure 5 As shown, a second C-shaped slot mounting plate 8 is provided between the wall sound-absorbing and sound-insulating panel 2 and the foundation embedded steel plate 3.

A second edge fixing piece 9 is provided at one end of the second C-shaped slot mounting plate 8 located inside the wall sound-absorbing and sound-insulating panel 2.

[0027] The beneficial effects of this utility model are as follows:

[0028] 1. The roof sound-absorbing and sound-insulating panel 1 and the wall sound-absorbing and sound-insulating panel 2 adopt a fully sealed slot connection.

Combined with the local snap-on fixing, the structural strength is greater and can withstand strong typhoons.

[0029] 2. The wall-mounted sound-absorbing and sound-insulating panel 2 and the H-shaped steel column 5 are fixed with Z-shaped clips, which makes the connection tighter and more stable, the seal more tight, and avoids noise leakage, resulting in better performance.
