Detailed Description
For the purpose of enhancing understanding of the present invention, the present invention will be further described in detail with reference to the following examples, which are provided for illustration only and are not to be construed as limiting the scope of the present invention.
As shown in fig. 1-3, the present embodiment provides a steam turbine casing for reducing noise, which includes a left sub-casing and a right sub-casing 1 disposed on the ground, wherein the cross section of the sub-casings 1 is fan-shaped, and the combined cross section of the two sub-casings 1 is semi-circular and covers the outside of the steam turbine; the sub-cover 1 is made of foamed aluminum; therefore, the semicircular cover shell formed by the left and right branch covers the outside of the steam turbine to insulate sound and reduce noise, the shape of the steam turbine is matched, the space is not occupied, and the effect is good.
The sub-cover 1 comprises an upper cover 2 and a lower cover 3, and the outsides of the upper cover 2 and the lower cover 3 are movably connected together through a hinge 4; the lower cover 3 is fixed on the ground, a bottom plate 5 is arranged on the ground on the outer side of the lower cover 3, a winding motor 6 is arranged on the bottom plate 5, a guide wheel 8 is movably arranged on the side surface of the lower cover 3 through a support arm 7, the guide wheel 8 is positioned on the outer side of the winding motor 6, and a rope 15 of the winding motor 6 is connected to the outer side edge of the upper cover 2 through the outer side of the guide wheel 8; the front and back sides of the upper cover 2 and the lower cover 3 are connected together through a plurality of gas springs 9. The joint of the two upper covers 2 is provided with magnetic blocks 12 with opposite magnetism, and the two magnetic blocks 12 are mutually attracted. The sub-cover 1 is divided into an upper cover 2 and a lower cover 3 which are connected through a hinge at the outer sides, the upper cover 2 can be driven to roll through a rolling motor 6 to enable the upper cover to turn outwards, so that the top of the cover shell is opened, the steam turbine is exposed, a crane can be easily used for hoisting and maintaining parts at the top of the steam turbine, and the large-area opening and heat dissipation are fast; and upper shield 2 and lower cover 3 are connected through a plurality of air springs 9, and when upper shield 2 need be closed like this, only need unreel coiling motor 6, and air spring 9 can be closed upper shield and lower cover automatically, adsorbs together through two magnetism opposite magnetism's magnetism piece 12 finally.
