Abstract
The utility model belongs to transmission line equipment insulation protection equipment technology field; The anti-bird pest protective cover of grading ring of wind resistance folding, comprises umbrella cover, middle ring and drag-line; Wherein, middle ring is be arranged on the keeper on grading ring axis, and umbrella cover central authorities are connected with middle ring top, and it is high that middle ring vertical length is greater than umbrella cover cone, and during drag-line connects, ring bottom and umbrella cover are close to edge; Umbrella cover, middle ring and drag-line all adopt silastic material manufacture; The beneficial effect of the grading ring anti-bird pest protective cover of the utility model wind resistance folding: by the anti-bird pest protective cover of a kind of grading ring having stayed structure to design; achieving power constitutional balance when not changing former pneumatic structure, solving the useful life problem of this kind equipment in wind-force larger area.
Description
technical field:
The utility model belongs to transmission line equipment insulation protection equipment technology field.
background technology:
Transmission line grading ring, due to the particularity of installation site and shape, is subject to bird pest impact.Cause damage for reducing bird pest, the mode of installing umbrella shape protective cover that adopts processes more.
Existing protective cover mostly is in small size and ring is set with umbrella cover; structural strengthening is carried out with ripple glaze; this design material usage is little; cost is lower is beneficial to production; but the particular surroundings requirement of wind-force larger area cannot be adapted to; cause umbrella cover to fracture in the turnover of beam wind subumbrella cover vertical tremor, useful life is very low.
Part protective cover is designed with the one-sided reinforcement of upper surface or lower surface; but effect is also not obvious; reason is: it is larger that beam wind subumbrella cover upper surface forms boundary-layer air flow velocity; lower surface large-size cavity flow slowing down; upper and lower surface pressure reduction causes umbrella cover upwards to turn down; Airflow Environment transposition afterwards, umbrella cover turns down downwards and circulates, thus umbrella cover continuous vibration.When adopting upper surface reinforcement, due to umbrella cover inclination angle problem, the poor ability that the anti-umbrella cover of reinforcement upwards turns down; When adopting lower surface reinforcement, the large cavity below umbrella cover can be divided into multiple areola having low-angle interior angle by reinforcement, and under beam wind, form eddy current, air velocity is greater than upper surface air velocity, causes umbrella cover to continue downward backfin and final deformed damaged.
summary of the invention:
The grading ring anti-bird pest protective cover goal of the invention of the utility model wind resistance folding: provide a kind of and effectively can prevent the anti-bird pest protective cover of the grading ring of windbreak, improves the useful life that relevant insulation is equipped in wind-force larger area.
The anti-bird pest protective cover of grading ring of wind resistance folding, comprises umbrella cover, middle ring and drag-line; Wherein, middle ring is be arranged on the keeper on grading ring axis, and umbrella cover central authorities are connected with middle ring top, and it is high that middle ring vertical length is greater than umbrella cover cone, and during drag-line connects, ring bottom and umbrella cover are close to edge; Umbrella cover, middle ring and drag-line all adopt silastic material manufacture.
Stayed structure is adopted to compare bottom surface reinforcing rib structure, advantage is: umbrella cover bottom surface cavity can not divided generation eddy current, the initial actuating direction that umbrella covers under beam wind maintains upwards, provide the pulling force that umbrella cover edge is downward simultaneously, realize balance, avoid that bottom surface reinforcing rib structure occurs downward pulling force is provided while change the problem in pneumatic direction.Corresponding with it, in adopting stayed structure to need, ring supports its mounting design to downward-extension.
Umbrella cover and middle ring leave installing port and install to facilitate equipment in the same side.
Preferably, umbrella cover installing port is designed with L-type platform, uses card article to be connected and fixed.
Umbrella cover upper surface has reinforcement, prevents from causing the downward backfin distortion of umbrella cover because birds droppings etc. sticks together.
The beneficial effect of the grading ring anti-bird pest protective cover of the utility model wind resistance folding: by the anti-bird pest protective cover of a kind of grading ring having stayed structure to design; achieving power constitutional balance when not changing former pneumatic structure, solving the useful life problem of this kind equipment in wind-force larger area.

Fig. 2 is the grading ring anti-bird pest protective cover plan structure schematic diagram of the utility model wind resistance folding;
Fig. 3 is the grading ring anti-bird pest protective cover lower surface configuration schematic diagram of the utility model wind resistance folding;
Fig. 4 is that the grading ring anti-bird pest protective cover card article of the utility model wind resistance folding installs partial sectional view;
In figure, umbrella cover 1, middle ring 2, drag-line 3, L-type platform 4, card article 5, reinforcement 6.
embodiment:
The anti-bird pest protective cover of grading ring of wind resistance folding, is made up of umbrella cover 1, middle ring 2 and drag-line 3; Wherein, middle ring 2 is for being arranged on the keeper on grading ring axis, and umbrella cover 1 central authorities are connected with middle ring 2 top, and middle ring 2 vertical length is greater than umbrella cover 1 and bores high, ring 2 bottom and umbrella cover 1 during drag-line 3 connects, drag-line 3 is 1/4th of umbrella cover 1 conical surface length with umbrella cover 1 junction distance umbrella cover 1 outer rim; Umbrella cover 1, middle ring 2 and drag-line 3 all adopt silastic material integrally manufactured.
Umbrella cover 1 and middle ring 2 have construction opening, and above-mentioned construction opening is in equipment the same side and conllinear.
Umbrella cover installing port both sides are designed with L-type platform 4, use card article 5 to be connected and fixed; Middle ring 2 installing port arranges bayonet socket.
Umbrella cover upper surface has reinforcement 6, and the quantity of reinforcement 6 is consistent with drag-line 3 with installation site, is 6 places.
