Description
Technical field:
The utility model relates to a kind of on-pole switch Bird's Nest scavenge unit based on insulating rod, is widely used in the removing work of all kinds of on-pole switch Bird's Nest of electric power system, belongs to electrical network distribution line O&M service technique field.
Background technology:
Bird's Nest is the common multiple harm of overhead distribution, be located in birds to move back the power network line of habitat, Bird's Nest is very serious to the harm of overhead transmission line, if remove the Bird's Nest at the place such as cross-arm, on-pole switch not in time, when running into sleety weather, very easily cause the faults such as overhead transmission line phase fault, single-phase earthing, cause tripping operation completely.
The device of existing removing Bird's Nest mainly uses the ledge of insulating bar head, operator station on the ground or step on bar, simultaneously keep enough safe distances with live part, hook is directly carried out to the Bird's Nest at cross arm of tower place and drags and push away, reach the object removing Bird's Nest.Although this kind of device can remove the Bird's Nest on cross-arm, but be difficult to remove to the Bird's Nest above on-pole switch, main cause is blocking of on-pole switch, staff directly cannot be hooked with external application insulating bar at safe distance, drag, Bird's Nest above buck switch.At present, want the Bird's Nest removed above on-pole switch to only have by line outage, live line working two kinds of methods.
It is unpractical nowadays that on-pole switch Bird's Nest is removed in overhead transmission line power failure, and birds are nested and have uncertainty, at set intervals circuit all can find that there is Bird's Nest, and therefore Utilities Electric Co. does not allow because Bird's Nest defect carries out line outage operation.
Live line working method removes on-pole switch Bird's Nest, and staff, by aerial lift device with insulated arm, first carries out the isolating and protecting measure at charged position, the Bird's Nest then above clear switch.But finding some potential safety hazards in practice, in Bird's Nest, often found that there is wire be mixed in branch, if any accidentally making wire contact to live part, serious accident of human electric shock can have been caused.The program of live line working is simultaneously comparatively complicated, and cost is also higher.Therefore this type of Bird's Nest poor stability is removed in live line working, program is complicated, the cost of overhaul is high, is not suitable for generally applying removing Bird's Nest above on-pole switch.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art device and provides that a kind of structure is simple, easy to use and flexible, coefficient of safety are high, with low cost, effectively can reduce the on-pole switch Bird's Nest scavenge unit based on insulating rod of the overhead transmission line O&M cost of overhaul.
The purpose of this utility model can be reached by following measure: a kind of on-pole switch Bird's Nest scavenge unit based on insulating rod, it is characterized in that it comprises base, gear mechanism, the bottom of base is provided with insulating rod screw interface groove, the top of base is provided with gear and buckles built-in groove, gear mechanism is linked to be integrated by the gear that pinion stand and pinion stand protrude and forms, gear is buckled and gear is buckled built-in groove and matched, gear is buckled built-in groove and is embedded with gear and buckles, the pinion stand of gear mechanism connects work jibs, base, gear mechanism and work jibs pass through wing nut, pad, wing screw tightens together, work jibs is "∧" type, corner angle α is 150 °, the front end of work jibs connects removes hook, remove two obtuse angles being connected by the connecting rod vertical with work jibs and connecting rod two ends of hook little link to be integrated form.
The utility model can produce following good effect compared with the prior art: the utility model effectively can solve the problem that common insulating rod cannot remove Bird's Nest above on-pole switch, easily there is the potential safety hazard of Danger Electric shock risk when live line working can be avoided to remove this type of Bird's Nest, evade red tape and higher cost when this type of Bird's Nest is removed in live line working.The Distribution Network Failure such as overhead transmission line phase fault, single-phase earthing that effective minimizing causes because of Bird's Nest, decreases tripping operation number of times, improves the power supply reliability of electrical network, avoid the loss that electrical network property is unnecessary.It has:
1. structure is simple, easy for installation.The opening angle of work jibs can regulate as required, after the angular adjustment of work jibs is good, pass through together with wing nut, pad, screw fastening with base and gear mechanism, base is connected with insulating rod by standard insulating rod screw interface, can complete.
2. coefficient of safety is high.Work jibs, base, wing nut, pad, screw all use insulating epoxy material, and action bars uses the insulating rod of relevant voltage grade.
3. applied widely.For the on-pole switch of different model, the Bird's Nest above on-pole switch can be removed.
4. use threshold low.Do not need to do quarantine measures to charged position, the preparation before work is simple, only needs to wear insulated shoes, tape insulation gloves.There is the advantage finding that defect is removed immediately.
5. reduce entreprise cost.This type of Bird's Nest poor stability is removed in live line working, program is complicated and need large-scale aerial lift device with insulated arm, High Performance Insulation masking material and a large amount of personnel to assist, and the cost of overhaul is high.Use this removing on-pole switch Bird's Nest device only to need 2 people to coordinate, use basic labour protection articles for use, this type of Bird's Nest removing work can be completed.There is the advantage that use cost is cheap.
