Description
Technical field
The invention belongs to removing ice of power transmission line to maintain equipment fields, and in particular to a kind of explosion with ammunition loading mechanism
Deicer.
Background technique
Transmission line of electricity is typically erected in open field environment, the moisture when winter environment temperature reduces, in air
It can condense and form icing on the transmission line, and powerline ice-covering will cause following harm:
(1) shaft tower is damaged.Transmission line icing is blocked up, and shaft tower machinery loading can be made more to carry and fracture.
(2) line tripping.For the route of conducting wire vertical arrangement, when the icing on layer conductor first falls off instantly (on conducting wire
Icing not necessarily fall off simultaneously), conducting wire will rise rapidly or jump above and below, cause phase fault, jump line switching
Lock, power failure.
(3) insulator chain inclination, conducting wire are seriously sagging.When ice covering thickness in each span of route is uneven, conducting wire sag
Great changes will take place by general, and suspension insulator is caused to tilt, and fitting bears biggish horizontal direction active force.It is blocked up in icing
In span, it is serious sagging and ground fault occurs to will cause conducting wire.
(4) after insulator chain icing, it will be greatly reduced insulation performance.When suspension insulator icing dissolves, possible shape
At icicle, keeps insulator chain short-circuit, cause ground fault.
Currently used mode of getting rid of the danger mainly has ice-melt and two kinds of mechanical deicing, and wherein ice-melting mode is in power transmission line
To realize ice-melt, concrete mode has trend distribution formula ice-melt (increase in the short time power line load and heat production), short for upper heating
Road formula ice-melt (transmission line of electricity suitable for three phase supply), high frequency pumping ice-melt are (using the kelvin effect of high-frequency high-voltage, defeated
Resistance loss is caused to generate heat and ice-melt on electric wire), it inevitably needs to carry out certain journey to transmission line of electricity using ice-melting mode
The transformation of degree, and need to consume big energy and heated, deicing cost and difficulty are all higher；And mechanical deicing is mainly adopted
It is carried out with the equipment being arranged on power transmission line, major way is using beaing, shake or blasting method carries out, and problem exists
In the general wind-force in power transmission line location is larger, and equipment is deflected by wind-force effect, it is difficult to effectively progress operation, and
Beat, shake by outside, the modes such as explosion are also difficult to smash ice sheet thicker on power transmission line so that deicing operation thing times function
Half, it is difficult to it achieves the desired results, fixes blasting body on ice sheet in advance using blasting method needs, explosion uses outer quick-fried mode,

The spare quick-fried bullet stored in magazine 205 is released and is pressed in explosion slot 203, as shown in figure 8, to complete the automatic dress of ammunition
It fills out, so that equipment realizes secondary filling in the case where midway is participated in without personnel automatically, extends cruising ability.
206 end of locking bar ontology is also connected with the damping ball 208 of elastic material.By damping ball 208 and gas-guide tube
Wall friction in 205, so that 206 rebound velocity of locking bar ontology slows down, avoiding locking bar ontology 206, quickly rebound leads to magazine telescoping cover
204 are knocked stuck, cause spare quick-fried bullet that can not release.
The present invention is driven using transmission shaft 3, is avoided and is installed the electrically driven elements such as motor in device noumenon 1, is guaranteed
Equipment is with good stability under blasting impact, and the blasting body of setting is fixed in drive sleeve 11, with device noumenon 1
Advance, the helical trajectory that drive sleeve 11 is drilled out with device noumenon 1 pulls blasting body in place, and blasting body diameter is less than track
Diameter when the resistance when pulling increases to device noumenon 1 and can not advance, ignites blasting body and smashes ice sheet, and the dress of front end
It sets at ontology 1 due to there is no explosion, can continue to advance along desired trajectory, personnel only need subsequent supplement blasting body, energy
The deicing for completing whole power transmission line, compared to traditional outer quick-fried formula deicing, deicing effect promoting is huge, and uses device noumenon
1 autonomous propulsion, reduces the personal height activity duration, alleviates the labor intensity of personnel.
