[0002] In recent years, the rapid development of power grid construction and the increasing size of cities have led to the emergence of noise-sensitive buildings such as residential buildings around newly built substations, necessitating the design of noise reduction structures for substations.

[0003] In existing substations, such as 110KV substations, the noise reduction structure is mainly achieved by adding sound insulation materials to the wall or inner side of the main transformer room, but no effective noise reduction design is carried out for the gates that need to be entered and exited. Simple soundproof doors are still used, which have poor sound insulation effect and are not conducive to ventilation and rain protection. In addition, the gates are large in size and are not convenient for entry and exit during routine inspections. Utility Model Content

[0010] Each of the longitudinal assembly parts is installed with a plurality of the first noise reduction plates, and each of the first noise reduction plates is sequentially stacked and installed in the assembly installation structure from bottom to top, and both ends of the noise reduction plate are embedded in two assembly grooves.

[0011] In a possible implementation, the first shutter is a waterproof shutter having a plurality of inclined blades.

[0012] In a possible implementation, an air inlet shutter is further provided on the back side of the waterproof shutter.

[0013] In a possible implementation, the first noise reduction panel is an assembled sound-absorbing partition.

[0014] In a possible implementation, the noise reduction door panel is a double-opening door;

[0015] The double-leaf door has two door leaves connected to the inner door frame via hinges, and a plurality of second noise reduction plates are installed on the upper part of each door leaf.

[0030] Among them, the portal frame steel beam 1 is an integrated steel frame structure or a steel frame structure mainly formed by welding and connecting square steel and H-shaped steel. The steel material can make it have better structural stability even at a large size, ensuring that it is more stable during use. The portal frame steel beam 1 is mainly divided into three areas, namely the first installation area 11 and the second installation area 12 and the formed inner door frame 13. The first installation area 11 for installing the first noise reduction plate 2 is mainly located in the upper area, and the second installation area 12 for installing the first blinds 3 is mainly located on both sides of the inner door frame 13. This can make full and reasonable use of other areas outside the inner door frame 13, and can respectively play the role of noise reduction, ventilation and entry and exit. The first noise reduction plate 2 can be a sound insulation board or sound absorption board installed in an existing modular manner, or it can be a plate with other forms or installation methods and noise reduction effect, without limitation.

[0031] Through the above technical scheme, the portal frame steel beam 1 effectively supports the large-sized door panel and installs related components. The first noise reduction plate 2 is installed in the large-area first installation area 11 on the upper part, which can play a better sound insulation role. The first shutter 3 installed in the second installation area 12 can facilitate ventilation or rain protection, so that the main transformer room can be ventilated. In addition, by installing a noise reduction door panel 4 of a smaller size on the basis of the portal frame steel beam 1, the supporting performance requirements or installation difficulty of the noise reduction door panel 4 can be reduced, and it can have a noise reduction effect, thereby improving the noise reduction effect of the overall noise reduction door.

[0038] Specifically, the first noise reduction plate 2 is an assembled sound-absorbing partition.

[0039] In an embodiment of the present application, the noise reduction door panel 4 is a double-opening door; the double-opening door has two door leaves connected to the inner door frame 13 by hinges, and a plurality of second noise reduction panels 5 are installed on the upper part of each door leaf.

[0040] The noise reduction door panel 4 adopts a double-opening biparting door provided with a second noise reduction panel 5, which can be conveniently opened and closed while also being able to achieve sound insulation and noise reduction. In the specific implementation process, the biparting door can also be provided with components such as door locks and handles 8.

[0041] Furthermore, in the two door leaves, a second shutter 6 is provided at the lower part of one door leaf, and a patrol door 7 is provided at the lower part of the other door leaf. By respectively providing the second shutter 6 and the patrol door 7 at the two door leaves of the biparting door, ventilation, defense and routine patrol operations can be further improved, and entry and exit are more convenient and quick.
