Description
Technical field
The utility model relates to the structural system of a kind of transformer station sound arrester, particularly relates to a kind of sound arrester of transformer station and the overall structure of fire wall.
Background technology
Have in the 220kV of esidential building community or the outdoor substation of more voltage levels around built, due to the noise of main transformer, the example causing community resident to complain to power department increases year by year, needs badly and reduces main transformer noise to the impact of surrounding environment.Because in transformer station place, electric fixtures is more, often above the area edge enclosure wall of station, set up noise barrier, this method needs to arrange along whole or most of enclosure wall, engineering quantity is larger, and leave noise of main transformer source hypertelorism due to noise barrier on enclosure wall, the defening effect played is unsatisfactory or in order to reach expection defening effect, needs the height increasing barrier, needs to reinforce enclosure wall basis or reconstruct.
Due to above reason, arrange sound arrester in the urgent need to the position near main transformer in transformer station, in district of transformer station, main transformer side arranges noise barrier, and common noise barrier way is divided into self-supporting and diagonal-bracing type.
Because noise barrier surface area is large, suffered Pressures is comparatively large, and in order to resist blast, self-supporting barrier needs to build the larger strip foundation of volume in bottom to resist the overturning moment that blast reaches basis; Diagonal-bracing type barrier then needs to arrange the opposing oblique floor-type support of blast and the basis of support every a segment distance, diagonal brace is towards transformer, can have an impact to electric operation, towards road edge, diagonal brace basis can only be dropped on road edge, but in the transformer station place run under road cable trench and water pipe gather, cannot removal cable and fire main in putting into operation, the space requirement of large-scale bar base bottom self-supporting barrier cannot be met, be also difficult to the basis meeting diagonal-bracing type barrier needs spatial placement floor oblique under road edge.
Therefore, those skilled in the art is devoted to develop a kind of sound arrester of transformer station and the overall structure of fire wall.

Detailed description of the invention
With reference to Fig. 1-Fig. 7, this detailed description of the invention is by the following technical solutions: a kind of sound arrester of transformer station and the overall structure of fire wall, comprise noise barrier 1, fire wall 2, steel truss 3, shaped steel column 4 and H profile steel beam 5, noise barrier 1 is arranged on main transformer 6 side, noise barrier 1 is by shaped steel column 4, the steel frame that H profile steel beam 5 forms is fixed, noise barrier 1 both sides are provided with the fire wall 2 can resisting noise barrier 1 Pressures, noise barrier 1 is connected with vertically disposed fire wall 2, noise barrier 1 top is provided with steel truss 3, steel truss 3 two ends are connected with fire wall 2.
It should be noted that described noise barrier 1 can be placed on main transformer 6 and need to reduce the side of noise, when main transformer 6 both sides all need noise reduction, sound arrester can be settled in both sides simultaneously.
This detailed description of the invention main transformer 6 side in Substation Station district arranges noise barrier 1, adopt the fire wall 2 of main transformer 6 as a kind of lateral elements of resisting the Pressures of noise barrier 1, steel truss 3 be set at noise barrier 1 top and be connected with fire wall 2 at two ends, improving lateral resisting rigidity further.
This detailed description of the invention is realized by following steps: (1), on the basis of the position of the preset noise barrier 1 in main transformer 6 side excavation groove as barrier, groove direction is vertical with fire wall 2 direction, concreting strip foundation in groove;
(2) in strip foundation, build more than several concrete short column 7 to Site Design absolute altitudes at a certain distance, wherein must comprise several permanent positions, it is characterized by fire wall 2 straight line and extend the intersection point with groove, concrete short column 7 arranges shaped steel column 4 and just connects with concrete short column 7; Strip foundation short column builds the narrow beam 8 of horizontal direction concrete with external position, it is shelved noise barrier 1;
(3) mount type steel post 4, highly about 8 meters, the pillar steel edge of a wing is parallel to main transformer 6 direction, arrange some roads H profile steel beam 5 at shaped steel column 4 each absolute altitude place to be connected with each road column, weldable steel seam on H profile steel beam 5, light sound-insulation plate 10 to insert on H profile steel beam 5 in seam, is assembled into noise barrier 1;
(4) main transformer 6 both sides are provided with fire wall 2 (frame construction or concrete panel), fire wall 2 is perpendicular to noise barrier 1, settle steel plate near the end surface of noise barrier 1 at some absolute altitude places at fire wall 2, and with bucketing bolt 11, steel plate and fire wall 2 end are fixed;
(5) noise barrier 1 framework two ends steel post in the face of main transformer 6 direction the edge of a wing on, several short girder steels perpendicular to noise barrier 1 are connected with bolt, consistent with the steel plate absolute altitude on fire wall 2, by the steel plate on the short girder steel that extends out from the steel column edge of a wing and fire wall 2 by being welded to connect;
(6) connect horizontal steel truss system at noise barrier 1 top bolt, make noise barrier 1 top hinged, bottom and basis just connect, and steel truss 3 two ends are bolted on fire wall 2;
(7) framework upper of noise barrier 1 is connected with fire wall 2 top by upper horizontal girder system, horizontal direction two ends are supported on fire wall 2 end by short girder steel, lower end is connected with basis by suspension column and short column, define a kind of power transmission clearly reasonable, solid and reliable, succinctly economic and practical combined structure system;
Blast suffered by this detailed description of the invention noise barrier 1 surface, except bottom is directly passed to ground, top blast passes to fire wall 2 by steel truss 3, and two end portions blast passes to the short girder steel be connected with the column edge of a wing by shaped steel column 4, finally pass to fire wall 2; The lateral rigidity that fire wall 2 provides can meet the blast drag that noise barrier 1 bears, therefore the skewed horizontal load of noise barrier 1 need not be set again, what also do not need the basic cross section of barrier to do is very large, finally forms the innovative structure structural system of taking up an area the very little noise barrier-steel truss-fire wall in space; Because integrally-built each component is that bolt connects, detachable maintaining is also very convenient, practical.
This detailed description of the invention is combined to form a kind of rock-steady structure system taking up room less by steel frame noise barrier, fire wall and steel truss, avoid and build the drawback that larger basis or Xiang Daoyuan arrange oblique floor-type support, defening effect is good, safety economy, highly effective, have wide market application foreground.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
