Description
Technical field
The present invention relates to cable corollary apparatus technical field, is specifically a kind of water-proof cable well.
Background technology
Cable run is when laying, every a segment distance, a cable shaft must be set, the importance of cable run is without the need to repeating, and the stability of the waterproof of cable shaft to cable run has a great impact, in the environment of rainy humidity, the continuation that cable shaft is subject to water invades, although amount is few, but the water in cable shaft cannot continue to drain in time, and cable shaft also easily mildews.
Existing patent document, such as publication No. is the Chinese patent application " in a kind of cable shaft warning device " of CN103354017A, it maintains easily personnel's maintenance cable well by arranging ponding autoalarm in cable shaft, make attendant just accurately can know that ponding appears in which cable shaft without the need to going into the well, final purpose guides attendant to clear up ponding in time to reach the object of cable shaft waterproof.
And for example notification number is the Chinese patent " cable shaft " of CN203270614U, it discloses a kind of structure of anti-ponding, namely by arranging collecting well, the water in cable shaft is introduced collecting well, then the water of attendant by all means in pump drainage collecting well just can realize the draining object of cable shaft, finally realizes cable shaft waterproof.
For another example notification number is the Chinese patent " anti-ponding cable shaft " of CN203160272U, it discloses a kind of structure of more effective anti-ponding, namely by arranging collecting well and arranging level sensing remote prompting device, when the water introducing collecting well in cable shaft reaches a certain amount of, attendant carries out draining for needing the collecting well of pump drainage, finally more effectively realizes cable shaft waterproof.
Above-mentioned disclosed technical scheme, the mode all only adopting structure to improve strengthens the waterproof of cable shaft, but all water is not continued in time to drain, the improved scheme of waterproof is not made to promote mildew-resistant well, therefore it seems only have the improvement of structure to be difficult to realize waterproof, mildew-resistant double effects at present simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of in the environment of rainy humidity, water can be continued in time drain, realize the water-proof cable well of waterproof, mildew-resistant simultaneously.
Technical scheme of the present invention is, water-proof cable well of the present invention, and it comprises well body, the low-lying place in the shaft bottom of well body is provided with sump, be provided with supersonic atomizer in sump, be provided with fog collecting hood above sump, the exhaust tube of fog collecting hood is communicated with escape pipe; The painting of well body inner surface is brushed with mildew-resistant and scolds water paint; Described mildew-resistant scolds the component of water paint and parts by weight to be: petroleum bitumen 40-60 part, styrene-butadiene latex 12-35 part, epoxy resin 6-8 part, stabilizing agent 0.1-0.3 part, mould inhibitor, emulsifier 0.5-1 part, water 15-30 part.
The above-mentioned stabilizing agent of the present invention is the one in pentaerythrite, xylitol, sweet mellow wine etc.; It can slow down reaction, keeps chemical balance, reduces surface tension, prevents the effects such as light, thermal decomposition or oxidation Decomposition; Ensure that the long-term homogeneous of coating exists simultaneously, not stratified, effective, stable performance.
The above-mentioned mould inhibitor of the present invention is phenol or pentachlorophenol, and adopt above-mentioned mould inhibitor fully can merge with main material petroleum bitumen, and can play very effective mildew-proof function, the time is long, effective.
The above-mentioned emulsifier of the present invention is alkyl dimethyl hydroxyethyl ammonium chloride, as there is methylol groups in ten alkyl dimethyl monomethylol ammonium chloride structures, the polarity increased, improve the compatibility ability to other organic compounds various, as reached abundant compatibility fusion with petroleum bitumen, butadiene-styrene rubber and epoxy resin etc., thus improve the overall uniformity consistency of water-repellent paint.
The above-mentioned petroleum bitumen of the present invention is 100# petroleum bitumen and the mixing of 70# petroleum bitumen, and weight proportion is therebetween: 100# petroleum bitumen: 70# petroleum bitumen=1:2-3(such as Xingtai City builds the pitch that grand pitch sells the above-mentioned model that Co., Ltd produces); The coupling mixing of above-mentioned bituminous material is very crucial, show that coating has good water resistance, anti-brittle performance and resistance to low temperature according to aforementioned proportion combined experiments remarkable, be useful in completely cable WIH in the environment of rainy humidity continue in time drain and prevent to mildew.
The present invention also discloses the preparation method that water paint is scolded in a kind of above-mentioned mildew-resistant:
(1) according to formula rate, first petroleum bitumen is heated to 120-160 DEG C, styrene-butadiene latex is heated to the liquid that 60-80 DEG C obtains melting; Then above-mentioned two kinds of liquids mixed and in mulser, carry out emulsification mixing 20-30min;
(2) then according to formula rate by epoxy resin, stabilizing agent, mould inhibitor, emulsifier, in mixing material carries out emulsification mixing 20-40min after joining step (1) emulsification after water mixes, and namely obtains mildew-resistant and scolds water paint.
During use, above-mentioned mildew-resistant scolded water paint to adopt burnjector mechanical to be sprayed at well body inner surface, coating thickness is 0.5-2mm; Adopt this thickness fully can ensure waterproof and the anti-mold effect of cable shaft inner surface, and coating continuous action is long, effective.The above-mentioned its preparation process of the present invention is simple, with short production cycle, easy construction.And, coating of the present invention can make coating in low temperature (-15 DEG C) not embrittlement owing to adding styrene-butadiene latex, thus the environment that fully can be applicable to underground low temperature, humidity and easily go mouldy, can ensure the adding of epoxy resin that coating has after excellent adhesion property and well body spray, do not ftracture, do not come off, thus fully keep the mildew-resistant of coating, the continuation of water resistance.
After adopting said structure, the present invention compared with prior art, have the following advantages: the present invention scolds water paint by being brushed with mildew-resistant in the painting of well body inner surface, mildew-resistant scolds water paint water can be guided to shaft bottom fast, then sump is guided to from shaft bottom, water base cannot stop, and the water in sump is just opened immediately when reaching the working value of supersonic atomizer and is made water fogging, water after atomization is discharged by exhaust tube, escape pipe can be existing sewer, an escape pipe parallel with cable pipeline also can be set separately, escape pipe arranges several giving vent to anger again, delivery port, like this, by the setting of such scheme, well body inner surface is substantially anhydrous, mouldy water environment is destroyed as far as possible, add the effect of mildew-resistant composition in coating, the present invention is made to have in the environment of rainy humidity, water can be continued in time drain, realize waterproof simultaneously, the advantage of mildew-resistant.
As improvement, fog collecting hood is taper; The span of the spacing of fog collecting hood and sump is closed interval [5 centimetres, 10 centimetres], and like this, fog collection efficiency is higher, is more conducive to Quick drainage.
As improvement, exhaust tube is provided with anti-fog return valve, like this, prevents fog from refluxing, is more conducive to draining.
