Power station environmental protection partition wall
Technical field
The present invention relates to a kind of power station environmental protection partition wall, particularly 1000kv ultra-high voltage transformer station protection, is applied to transformer station.
Background technology
The noise that 1000 kilovolt high voltage substation run durations produce is mainly from the electromagnetic noise of the electric fixturess such as power distribution equipment outside main transformer, high voltage reactor, line breaker and room and the aerodynamic noise of cooling fan generation.
For the noise that effectively controls environment, the noise that 1000 kv substation engineerings are produced does not disturb residents, and according to < < Industrial Enterprise Factory Boundary ambient noise discharge standard > > (GB12348-2008) 2 class standards, requires: between daytime, be controlled at 60dB (A), night and be controlled in 50dB (A).
The sound insulation enclosure wall of tradition transformer station is common brick enclosure wall, and defening effect is poor, and without sound absorption function, makes transformer station's external noise control range large, causes removal area large, and reimbursement for expenses is high.Therefore for the problems referred to above, are, objects that the present invention studies.
Summary of the invention
The object of the present invention is to provide a kind of power station environmental protection partition wall, contribute to solve the effectively problem such as noise reduction of existing transformer station.
Technical program of the present invention lies in:
An environmental protection partition wall, comprises enclosure wall body of wall, it is characterized in that: on the outside wall of described enclosure wall body of wall, be covered with not punch metal plate of one deck, the inner side wall of described enclosure wall body of wall is provided with one deck vacuum glass.
Wherein, the top of described vacuum glass is provided with one deck blinds mesoporous metal plate, and bottom is provided with one deck chromatic steel sandwich plate.
Between described blinds mesoporous metal plate and vacuum glass, be also provided with one deck glass wool cloth.
Between described glass wool cloth and vacuum glass, be filled with sound absorption cotton and sound insulation damping felt plate.
Described metal sheet is galvanized steel plain sheet or aluminium alloys.
The invention has the advantages that: structural strength of the present invention is high, lightweight, handsome in appearance, sound absorption is functional and cost is lower.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the embodiment of the present invention.
Fig. 2 is the side-looking structural representation of the embodiment of the present invention.
The specific embodiment
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
Referring to figs. 1 to Fig. 2, the present invention relates to a kind of power station environmental protection partition wall, comprise enclosure wall body of wall 1, on the outside wall of described enclosure wall body of wall 1, be covered with not punch metal plate 2 of one deck, the inner side wall of described enclosure wall body of wall 1 is provided with one deck vacuum glass 3.
The top of above-mentioned vacuum glass 3 is provided with one deck blinds mesoporous metal plate 4, and bottom is provided with one deck chromatic steel sandwich plate 5.
Between above-mentioned blinds mesoporous metal plate 4 and vacuum glass 3, be also provided with one deck glass wool cloth 6.
Between above-mentioned glass wool cloth 6 and vacuum glass 3, be filled with sound absorption cotton and sound insulation damping felt plate 7.
Above-mentioned metal sheet 2,4 is galvanized steel plain sheet or aluminium alloys.
Specific embodiment of the invention process: 1000 kv substation antinoise soundproofing enclosure tops are divided into sound absorption board member and form, its acoustical board structure is interior survey metal piercing (blinds hole), back side backplate is punch metal steel plate not, and metal sheet is galvanized steel plain sheet or aluminium alloys.And in interior filling sound absorption cotton and sound insulation damping felt plate, and cover the glass wool cloth of Rainproof moisture-proof.Bottom is the member unit that only sound insulation does not absorb sound, and its structure is chromatic steel sandwich plate.The thickness of acoustic screen baffle is 100mm.It has efficient soundproof effect vacuum glass, generally adopts tempered glass, so not only safety but also can reach the needs of sound insulation and noise reduction.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
