Description
Technical field
The utility model relates to transformer station's building structure, particularly a kind of transformer station dust control and noise absorption ventilation unit.
Background technology
Along with the continuous high speed development of urban distribution network, various forms of 220kV, the indoor substation of 110kV is built in each city, inevitably to live the proximate gathered personnel, indoor electric equipment particularly main transformer in current transformer station, when work, not only produce higher noise, and produce very large heat, and the noise of transformer station is mainly based on Middle and low frequency noise, this Middle and low frequency noise wavelength is large, decay is slow, strong to ordinarily resident's building penetration power, and in high pressure and Ultra-high Voltage Substations, high pressure line, high voltage bus and part electric equipment corona discharge sound are also noise sources, the healthy of resident and living environment are had a strong impact on, no matter be the limit value requirement facing state's laws regulation, or in order to meet the responsive demand of the masses for living environment, the noise reduction sound-deadening of transformer station is all the importance that current transformer station Architectural Equipment needs to improve, moreover, the addressing district of transformer station may near road or construction site particularly coal mining area, if suck a large amount of dust particularly combustible dust or combustible fibre in transformer station, not even safety factor can be had a huge impact to the operation of converting equipment, the noise-reducing and dustproof of transformer substation air vent is all the major issue needing solution badly, add and need to consider protection against the tide, the consideration of the aspects such as anti-toy, existing old-fashioned transformer station ventilation unit is except possessing single ventilation and heat function, substantially the functions such as noise reduction sound-deadening are not possessed, more can not meet the demand of above-mentioned each side.
Utility model content
The utility model, for the defect existed in above-mentioned prior art, provides transformer station's dust control and noise absorption ventilation unit that a kind of Air Filter does not need disassembly, cleaning, excellent noise reduction effect, protection against the tide, anti-toy.
The technical scheme that the utility model is taked for the above-mentioned Problems existing of solution is: transformer station's dust control and noise absorption ventilation unit comprises the membrane filter be arranged on inside body of wall, be arranged on the ventilation shutter in body of wall, described ventilation shutter comprises framework and is arranged on the spaced some pieces of blades in framework, silencing plate is provided with in blade, described leaf cross-section is in falling " V " font, the vent passages of bending shape is formed between described blade, described membrane filter comprises dust-filtering net and cleaning rod, described cleaning rod is movably connected on screen pack by connecting axle, described cleaning rod is arranged at intervals with cleaning brush relative to one end of dust-filtering net, the two ends up and down of dust-filtering net are respectively arranged with card article, body of wall is provided with the groove corresponding with card article.
Further, the bending angle of described blade is 80-120 °.
The beneficial effects of the utility model: compared to existing technology, the utility model adopts the blade of inverted V-shaped structure and built-in silencing plate, noise is prevented outwards to propagate, noise reduction improves greatly, and rainwater can be made can not to enter transformer station indoor, do not need dismounting during the easy for installation and cleaning of anti-dust filter mesh, there is the multi-functional of dust-proof, noise reduction, protection against the tide, anti-toy.
Accompanying drawing explanation
Fig. 1 is the main sectional structure schematic diagram after the utility model is installed,
Fig. 2 is the right TV structure schematic diagram of the utility model,
Fig. 3 is the left TV structure schematic diagram of the utility model.
In the drawings, 1, framework 2, vent passages 3, blade 4, body of wall 5, groove 6, cleaning brush 7, connecting axle 8, cleaning rod 9, dust-filtering net 10, card article 11, silencing plate.
Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, in conjunction with embodiment, the utility model is described in further detail with reference to the accompanying drawings below.
As Fig. 1, 2, shown in 3, transformer station's dust control and noise absorption ventilation unit, comprise the membrane filter be arranged on inside body of wall 4, be arranged on the ventilation shutter in body of wall, the spaced some pieces of blades 3 that described ventilation shutter comprises framework 1 and is arranged in framework, the side frame of framework and top margin frame, boundary frame area, blade screw or rivet joint, silencing plate 11 is provided with in blade, blade is aluminium sheet, the perforated plate that galvanized steel plain sheet or corrosion resistant plate are made, the silencing plate of filling comprises centrifugally glass-wool, Vestolit, one or more of ore deposit rock wool, described leaf cross-section is in falling " V " font, the vent passages 2 of bending shape is formed between described blade, described membrane filter comprises dust-filtering net 9 and cleaning rod 8, it is online that described cleaning rod is movably connected in dust-filtering by connecting axle 7, described cleaning rod is arranged at intervals with cleaning brush 6 relative to one end of dust-filtering net, cleaning brush is soft strip, end is spherical, when needs cleaning, only need rotating cleaning brush the dust on screen pack can be removed, dust-filtering net is made up of nonwoven fabrics or glass fibre, shape is staggered grid-like of longitude and latitude, thickness is 50 ~ 90mm, be more than 99.1% to effective stop rate of the dust granules of 0.1 ~ 0.3 micron, the two ends up and down of dust-filtering net are respectively arranged with card article 10, body of wall is provided with the groove 5 corresponding with card article, during installation, only card article need be snapped in groove.
Further, the angle (i.e. the angle of the two ends bending part formation of blade) of described blade is 80-120 °, preferably 90 °.
Above-mentioned spaced " V " character form structure not only makes outside rainwater be difficult to enter, play good moisture-proof role, and as mouse, the toys such as snake are also difficult to enter transformer station indoor, vent passages and the silencing plate of unique bending shape have very large inhibition for sonic propagation of making an uproar, noise is multiple impacts and the absorption by deadener in the passage of bending shape, large high attenuation, test through many experiments, the sound deadening capacity that the utility model can reach noise reduction shutter is 10-22 decibel (dB), the pressure loss≤28Pa, every square metre of ventilation quantity is 1600m
3/ h-2900m
3the effect of/h.
