Description
Technical field
The present invention relates to a kind of comb cabling protection tool.
Background technology
Along with the development in city, make the electricity consumption increase in density in city, power consumption is also increasing.And aerial condutor is subject to the restriction of ground, big city, space, environmental protection and safety, therefore defeated, distribution line can only adopt cable to enter underground, and develops into cable distribution network.Overhead cabling method should be determined according to factors such as electric pressure, final amt, execution conditions and initial investments, is usually divided into following several mode:
(1) directly buried installation: generally more easily implement is the system of laying of economical and convenient, but maintenance, safeguard inconvenient.
(2) groove lays: invest higher, facts have proved in a large number, runs year long afterwards, and often occur that trench cover fracture, breakage are complete, ground sewage infiltrates heavy corrosion cable in ditch, the problem such as cause that cable insulation degenerates.
(3) comb lays: general than raceway groove reduced investment, and is avoiding cable line to influence each other, and improving fail safe aspect has obvious advantage, and repair and maintenance is convenient.
According to compare above can find out cable duct bank lay have that pipeline path adaptability is good, the construction period is short, the scope of operation is little, maintenance, advantage easy to maintenance, therefore, by adopting cable duct bank system of laying in the cable pipeline network construction of cities and towns.
Cable duct bank mainly adopts the different materials such as pipe of cement, steel pipe, hard polyethylene pipe, glass fiber reinforcement plastic pipe, pipe of cement is common materials, in cabling process, if not thorough to cable duct bank cleaning, it is rough etc. to there is concrete burr, stone block, iron and steel foreign matter or cable duct bank interface in cable duct bank inside, in laid processes, all will certainly cause damage to cable jacket, cause cable insulation degree to reduce.
According to statistics, 2007 to 2013 the comb cabling total numbers in certain city are 696, and occur that damaged number is 85, breakage rate is 12.21%, therefore prevent comb cable laying outlet breakage from having become current problem demanding prompt solution, a large amount of human and material resources are all taken every year to this company and solves this thing, but still effectively cannot avoid the generation of cable failure.
Existing comb cable laying tool comprises:
(1) broom-type dust removing tool; Besom clears up comb the most common to be also prevailing dust removing tool, besom head to be stretched into comb inside, removes for foreign matters such as comb inside rubble, soil blocks, to reach the object of the inner impurity of cleaning comb.Besom serves certain effect for the inner impurity of removing comb and foreign matter; but it also has a significant defect; be exactly to operating environment claimed range is comparatively large and its head is not firm; to the firmly hard foreign matter DeGrain such as concrete stone block, iron wire; and may damage besom; it is caused to lose effect originally; and when using besom to clear up it; often there will be the phenomenons such as besom head damages, besom handle position fractures and cleaning effect is invalid, thus have impact on the effect of dispelling foreign matter.
(2) helmet formula protection tool; This instrument has the effect of protection cable end, cable head can be avoided to be subject to major injury, have certain cleaning effect in cabling process, but does not have positive effect for firmly foreign matter, does not have the effect of effective protective cable.
