Description
Technical field
The present invention relates to electrical circuitry equipment manufacturing technology, relate more specifically to a kind of water being suitable for and assembling at the scene
The docking structure of mud electric pole.
Background technology
Modern society has be unable to do without electric power, and the electricity that power plant sends must be transmitted by electric power just can deliver to user
End, to ensure to produce and needed for life.Electric pole is indispensable electrical circuitry equipment in electric power transmitting procedure.
Electric pole uses rod mostly in early days, but along with the development of technology, present rod is eliminated, takes and generation
Be steel tower and cement electric pole.Compared with steel tower, a large amount of saving steels of cement electric pole energy, reduce circuit and make
Valency, operation maintenance is simple, and maintenance workload is few, and service life is the most long, up to 30～50 years, because of
This cement electric pole has bigger superiority and is more widely used.
But cement electric pole is from heavy sensation of the body, transport inconvenience, and the restriction of cement electric pole Preparation equipment, disposably makes
The cement electric pole limited length system produced.Generally more than 8 meters are accomplished by using segmentation manufacture, the most at the scene
Set up again after welding.In existing technology, one end that cement bar segment need to be docked is provided with a steel plate
Circle, is setting up scene, after being docked by the steel plate ring of two cement bar segment, with the annoying weldering of electric welding by two steel plates
Lap welding is connected together, and then eliminates rust the steel plate ring surface after welding, and brushes corrosion resistant coating.
But, the such docking structure of cement electric pole exists clearly disadvantageous, though steel plate ring is through preservative treatment,
But in harsh natural environment, corrosion resistant coating quickly can aging come off so that steel plate ring external demand and corroded.
Even if corrosion resistant coating is in the case of intact, owing to cement has seepage of water, rainwater can penetrate into steel by cement
Plate circle, also can accelerate the corrosion of steel plate ring.The corrosion of the steel plate ring intensity of joint, to cement electricity
Bar causes potential safety hazard.On the other hand, steel plate ring and the coefficient of expansion of cement, physicochemical properties exist very
Big difference, colding and heat succeed each other, under the natural environment that exposes to wind and rain, the cement touched with steel plate ring holds very much
Easy-weathering, therefore the cement weathering speed near steel plate ring is far longer than the air slaking speed at other positions of cement electric pole
Degree so that cement electric pole intensity near steel plate ring reduces gradually, thus has influence on the safety of cement electric pole
Performance, decreases the service life of cement electric pole.
In routine use and maintenance process, cement electric pole it is frequently necessary to wiring, to meet temporary electricity need
Ask, but wiring is the most pretty troublesome every time.
Summary of the invention
The technical problem to be solved is just to provide a kind of dock cement electric pole having storage line function,
Have that antiseptic property is good, intensity is high, good waterproof performance, length in service life, advantage that safety is good, while side

Detailed description of the invention
As depicted in figs. 1 and 2, for overlength can not cement electric pole made in one piece, use segmentation manufacture,
The present embodiment uses two sections of manufactures, the first bar segment 1 and the second bar segment 2, two bar segment will be divided into by cement electric pole
Manufacture respectively.The top of the first bar segment 1 is provided with the first bar segment steel plate ring 3；In the second bar segment 2
Bottom is provided with the second bar segment steel plate ring 4, and the external diameter of the two steel plate ring is identical, and less than two bar segment
External diameter.
First bar segment steel plate ring 3 and the welding of the second bar segment steel plate ring 4 form all-in-one-piece Interal fixation circle,
Interal fixation circle surface-coated has preservative treatment layer 6.It is externally provided with outer protective structure, outward at preservative treatment layer 6
Layer safeguard structure includes the putty layer 7 arranged outside preservative treatment layer, and described putty layer 7 is externally provided with carbon fiber and strengthens
Layer 8.Wherein, described putty layer 7 uses epoxy anticorrosion putty or Vinylidene Chloride anticorrosive putty.Described carbon fiber
Enhancement Layer 8 uses epoxy glue or polyvinyl gluing and be fixed on the surface of putty layer 7.
After first bar segment 1 and the second bar segment 2 are transported to erection scene, by the first bar segment steel plate ring 3 and second
Bar segment steel plate ring 4 docks and guarantees coaxial, is welded on by two steel plate rings with electric welding or gas welding the most at the scene
Together.After welding, carry out derusting anti-corrosive process, form preservative treatment layer 6.In the conventional technology, often
Carrying out field polish rust cleaning with sand paper or emery wheel, job site dust pollution is serious.Therefore, the present invention uses
Derusting anti-corrosive one-step method Non-water washing processes technique, and job site, will not be to environment without dust.Tool
The surface treatment liquid of body employing formula as below:
Phosphoric acid (65%): 200～350ml/L
Zinc oxide: 15～30g/L
Polyhydroxy acid: 2～30g/L
Sodium molybdate: 2～20g/L
Surfactant: 0.2～5g/L
Wherein, it is preferred to use the surface treatment liquid of formula as below:
Phosphoric acid (65%): 250ml/L
Zinc oxide: 20g/L
Polyhydroxy acid: 15g/L
Sodium molybdate: 10g/L
Surfactant: 2g/L
Polyhydroxy acid includes citric acid, tartaric acid, gluconic acid etc., conventional citric acid；Surfactant is
Conventional nonionic surfactant, such as OP-10, TX-10, triton x-100 etc..
It is very simple that derusting anti-corrosive one-step method Non-water washing processes technique, only need to be on steel plate ring surface brushes one layer
State surface treatment liquid, after it dries naturally, the rusty scale on steel plate ring surface can be converted into preservative treatment layer 6,
This preservative treatment layer 6 has good corrosion resistance, it is possible to follow-up putty layer has good adhesion.
After preservative treatment layer 6 parches completely, last layer putty can be scraped on its surface, form putty layer 7.
The effect of Puttying layer, in addition to the soldered 5 between by two steel plate rings is filled and led up, also has waterproof action,
Prevent outside rain penetration from entering, and then corrosion steel plate ring.After putty layer 7 solidification, with sand papering to greasy
Sublayer 7 outer surface flushes the construction that can carry out next step with the outer surface of cement electric pole.
In order to prevent the cement air slaking near steel plate ring, stop the infiltration of rainwater and cement electric pole joint is entered
Row reinforcement processes, and the present invention uses the processing method that carbon fiber winding strengthens.Due to carbon fiber have intensity and
Modulus is high, and density is low, higher than performance, and without creep, fatigue durability is good, and thermal coefficient of expansion is little, corrosion resistance
The good advantage waited, will be wrapped in the outside of putty layer 7 layer by layer after its impregnation, formed after it solidifies firm and
The carbon fiber enhancement Layer 8 that intensity is good.
The intensity of carbon fiber enhancement Layer 8 and the proportional relation of its thickness, therefore the thickness of carbon fiber winding should not
Less than 5mm.And carbon fiber enhancement Layer 8 two ends should exceed the two ends of putty layer 7, stretch out at least 1cm,
The most just there is enough stiffening effects.Epoxy glue commonly used by glue for carbon fiber winding or polyvinyl glue is
Can, glue used can be modulated the most before use, according to construction requirement, permissible by adjusting formula
Change hardening time, beneficially site operation.
