Abstract
The utility model discloses a corrugated pipe capable of automatic adjustment used for a GIS belonging to the GIS device field. The corrugated pipe comprises a corrugated pipe and a plurality of supporting structures disposed between an upper flange and a lower flange of the corrugated pipe. Each of the supporting structures is constituted by an automatic adjustment screw rod and an installation adjustment screw rod, which are respectively fixedly disposed on the upper flange and the lower flange by a locking nut and an installation adjustment nut, and in addition, automatic adjustment disc springs are disposed between the locking nut and the flanges. The corrugated pipe is advantageous in that the automatic adjustment screw rods and the installation adjustment screw rods are independently used, and the installation adjustment can be guaranteed, and at the same time, the automatic adjustment during the use can be realized at the same time, and therefore the corrugated pipe can be used to absorb the expansion caused by the heat-expansion and cold-contraction automatically, and the installation adjustment can be realized, and at the same time, the automatic contraction expansion adjustment can be realized during the operation, and the corrugated pipe is suitable for being used in various GIS device operation environments.
Description
Technical field
The utility model belongs to GIS apparatus field, is specifically related to a kind of GIS with can automatically regulating bellows.Background technology
Along with developing rapidly of power industry and power grid construction, the especially rapid construction of intelligent grid, increasing transformer station, current conversion station etc. have been realized even unattended operation of few man on duty.Large-scale power grid construction is also increasing for the demand of Cubicle Gas-Insulated Switchgear (being called for short GIS equipment), highly intelligentized trend is also had higher requirement to GIS equipment, wishes that CIS equipment can reach the requirements such as volume is small and exquisite, easy to operate, reliability is high, non-maintaining.
Due to the temperature difference of GIS equipment self and the temperature difference influence of place to use, CIS equipment is wanted to absorb owing to equipment and basis expanding with heat and contract with cold and cause swell increment, guarantee the safe and reliable operation of GIS equipment, therefore at GIS equipment room, the bellows that can absorb swell increment is installed, but this kind of bellows adopts the form pre-fixing to install, bellows cannot regulate automatically, therefore absorption equipment swell increment in use completely.Utility model content
The defect existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of GIS with can automatically regulating bellows.
The utility model is to be achieved through the following technical solutions:
A kind of GIS is with can automatically regulating bellows, comprise bellows, between the upper and lower flange of bellows, be provided with some groups of supporting constructions, every group of supporting construction consists of automatic adjusting screw(rod) and installation adjusting screw(rod), automatically adjusting screw(rod) and installation adjusting screw(rod) are fixed on the upper and lower flange of bellows by locking nut and installation adjusting nut respectively, are also provided with automatic regulation disc spring group between described locking nut and flange.
Some groups of described supporting constructions are distributed between the upper and lower flange of bellows.
Described supporting construction is 4 groups.
When described bellows is during in installment state, described locking nut unclamps, and regulation disc spring group is in the state of not stressing automatically.
When described bellows is in running order, described locking nut is fastening, and automatic regulation disc spring group is in uniform stressed state, and installation adjusting nut unclamps.
Described installation adjusting nut and bellows spacing 10～20mm.
Compared with prior art, the utlity model has following useful technique effect:
The supporting construction of bellows of the present utility model consists of automatic adjusting screw(rod) and installation adjusting screw(rod), between locking nut on automatic adjusting screw(rod) and bellows flange, be provided with automatic regulation disc spring group, when mounted, dish spring group does not stress, and by adjusting nut is installed, completes installation requirement; When bellows is in running order, locking nut is fastening, and dish spring group, in uniform stressed state, is installed adjusting nut and unclamped, and makes bellows to be realized automatically and being regulated by dish spring group.Automatic adjusting screw(rod) of the present utility model and installation adjusting screw(rod) are independently used, when having guaranteed that adjusting is installed, can meet again the automatic adjusting in use procedure, thereby the swell increment that can make the good automatic absorption of bellows cause owing to expanding with heat and contract with cold, when meeting installation adjusting, also meet the operating automatic convergent-divergent of work and regulate, thereby applicable various GIS equipment operating environments are used.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1～2, the self-adjustable bellows of GIS of the present utility model, comprise bellows 6, between the upper and lower flange of bellows 6, be provided with 4 groups of supporting constructions, every group of supporting construction consists of automatic adjusting screw(rod) 3 and installation adjusting screw(rod) 4, automatically adjusting screw(rod) 3 is fixed on flange by locking nut 2, adjusting screw(rod) 4 is installed and by adjusting nut 5 is installed, is fixed on flange, is also provided with automatic regulation disc spring group 1 between locking nut 2 and flange.
Referring to Fig. 3, when installation regulates, locking nut 2 is unclamped, make not pressurized of automatic regulation disc spring group, regulate the installation adjusting nut 5 of installing on adjusting screw(rod) 4, make bellows 6 meet installation requirement, and the spacing 10～20mm of adjusting nut 5 and bellows 6 is installed.
Referring to Fig. 4, when in running order after installation, adjusting lock nut 2 makes automatic regulation disc spring group 1 after uniform stressed state, locking nut 2 is fastening, then unclamp adjusting nut 5 is installed, now, 6 of bellowss can be realized automatically and being regulated by automatic regulation disc spring group 1.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model; can not assert that embodiment of the present utility model only limits to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; can also make some simple deduction or replace, all should be considered as belonging to the utility model and determine scope of patent protection by submitted to claims.
