Description
Technical field
The present invention relates to a kind of comb cabling protection tool.
Background technology
Development along with city so that the electricity consumption increase in density in city, power consumption is the most increasing.And aerial condutor is subject to
To the restriction of ground, big city, space, environmental conservation and safety, the most defeated, distribution line can only use cable to enter underground,
And develop into cable distribution network.Overhead cabling method should be according to electric pressure, final amt, execution conditions and initial investment
Determine etc. factor, be generally divided into following several ways:
(1) directly buried installation: be typically easier to implement, be the system of laying of economical and convenient, but maintenance, maintenance inconvenience.
(2) groove lays: invest higher, a large amount of it was verified that run year long afterwards, trench cover fracture, breakage often occurs not
Entirely, ground sewage penetrates into heavy corrosion cable in ditch, the problem such as cause that cable insulation degenerates.
(3) comb lays: general ratio raceway groove reduced investment, and is avoiding cable run to influence each other, and improves safety aspect
There is obvious advantage, and repair and maintenance is convenient.
Can be seen that cable duct bank lays and has that pipeline path adaptability is good, the construction period is short, the scope of operation according to comparing above
Little, maintenance, advantage easy to maintenance, therefore, by using cable duct bank system of laying in the cable pipeline network construction of cities and towns.
Cable duct bank mainly uses several materials such as pipe of cement, steel pipe, hard polyethylene pipe, glass fiber reinforcement plastic pipe
Material, pipe of cement is common materials, during cabling, if not thorough to cable duct bank cleaning, deposits inside cable duct bank
Rough etc. at concrete burr, stone block, iron and steel foreign body or cable duct bank seam, all will certainly be right in laid processes
Cable jacket causes damage, causes 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 bar number is
Article 85, breakage rate is 12.21%, therefore prevents comb cable laying outlet breakage from having become current problem demanding prompt solution, right
This company the most all takes substantial amounts of human and material resources and solves this thing, but still cannot be prevented effectively from the generation of cable failure.
Existing comb cable laying tool includes:
(1) broom-type dust removing tool;Besom is that clearing up comb most common is also the most common dust removing tool, by besom head
Stretch into inside comb, be purged for foreign bodies such as comb inside rubble, soil blocks, to reach to clear up the mesh of the internal impurity of comb
's.Besom serves certain effect for removing the internal impurity of comb and foreign body, but it also has a significant defect, just
It is to working environment claimed range is relatively big and its head is the firmest, to hard foreign body effects such as firm concrete stone block, iron wires
Inconspicuous, and besom may be damaged, cause it to lose effect originally, and when using besom that it is cleared up,
Often occur that besom head damages, besom handle position fractures and the phenomenon such as cleaning effect is invalid, thus have impact on dispel different
The effect of thing.
(2) helmet formula protection tool;This instrument has the effect of protection end, can avoid in cabling process
Cable head, by major injury, has certain cleaning effect, but does not has positive effect for firm foreign body, do not had
The effect of effect protective cable.
Summary of the invention
