Abstract

The invention discloses a dustproof bird-prevention wire-protection device for an inlet hole and an outlet hole. The device provided by the invention comprises an annular plugging device and an annular seal device, wherein the annular plugging device comprises two semi-circle plugging pipes, and the two semi-circle plugging pipes are in movable connection; and a filler is arranged in the annular seal device, the annular plugging device of a matched model is manufactured according to the sizes of the inlet hole and the outlet hole, and the inner wall of the annular plugging device is provided with the annular seal device. when the device is in use, the annular plugging device and the annular seal device are sleeved on the inlet hole and the outlet hole, the annular plugging device comprises two semi-circle plugging pipes, therefore the device can be arranged on the inlet hole and the outlet hole conveniently; when the annular plugging device and the annular seal device are fixed on the inlet hole an the outlet hole, a small hole is pricked on the annular seal device, and since the annular seal device is in vacuum packing, the annular seal device is aerated and expands to seal the inlet and the outlet after the hole is pricked, thereby achieving dustproof, bird-prevention and wire-protection effects.

Description

The dustproof anti-bird line protection device into and out of the line hole
?
Technical field
The invention belongs to the power circuit technical field, be specifically related to a kind of anti-bird line protection device that prevents dust into and out of the line hole.
Background technique
In power circuit; Transformer batch meter, electric closet etc. into and out of the line bore open all greater than into and out of linear diameter; Cause into and out of the line bore open excessive; In batch meter, electric closet, nest to live in peace for like this birds and bring chance, thereby cause equipment burnout accidents such as short-circuit between conductors, table meter easily, and bird's nest is heated and also might causes and catch fire; Be exactly to contact for a long time with irony batch meter, electric closet etc. in addition into and out of line; Be easy to cause isolation layer worn-off with contact position electric wires such as batch meter, electric closet, cable; Cause phase fault thus and burn measuring apparatus, controller switching equipment etc., cause damage for enterprise and user; Moreover be exactly poorly sealed into and out of the line hole a large amount of dusts are got into, cause instrument inaccurate or damage.
Summary of the invention
The objective of the invention is to avoid above-mentioned deficiency of the prior art, and provide a kind of dustproof anti-bird respond well, effectively protect power circuit, the dustproof anti-bird line protection device into and out of the line hole easy to use.
Realize that the technological scheme that the object of the invention adopted is: a kind of anti-bird line protection device that prevents dust into and out of the line hole; Comprise annular blocking device and ring seal device; Said annular blocking device comprises two semicircular ring shutoff pipes; Said two semicircular ring shutoff pipes flexibly connect, and said annular blocking device is provided with inwall, and said ring seal device is enclosed within on the blocking device inwall.
In the said ring seal device packing is set, said ring seal device is set to vacuum packaging.
Because the present invention installs annular locking device according to making the annular blocking device that model is complementary into and out of the line hole size at annular blocking device inwall.During use, annular blocking device and ring seal device are enclosed within on line, because annular blocking device comprises two semicircular ring shutoff pipes; Institute is so that be installed on line; When annular blocking device and ring seal device cover are fixed on behind the line hole, prick an aperture to the ring seal device, because said ring seal device is set to vacuum packaging; So make its inflation to seal behind the bundle hole, the effect of can reach dustproof, anti-bird, protecting line into and out of the line hole.The dustproof anti-bird of the present invention is respond well, effectively protect power circuit, easy to use.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of annular blocking device among the present invention.
Embodiment
Like Fig. 1; Shown in Figure 2: a kind of anti-bird line protection device that prevents dust into and out of the line hole; Comprise annular blocking device 1 and ring seal device 2, said annular blocking device 1 comprises two semicircular ring shutoff pipes 3, and said two semicircular ring shutoff pipes 3 flexibly connect; Said annular blocking device 1 is provided with inwall 4, and said ring seal device 2 is enclosed within on the blocking device inwall 4.
In the said ring seal device 2 packing is set, said ring seal device 2 is set to vacuum packaging.
Utilize the present invention,, annular locking device 2 is installed at annular blocking device inwall 4 according to making the annular blocking device 1 that model is complementary into and out of the line hole size.During use; Annular blocking device 1 is enclosed within on line with ring seal device 2, because annular blocking device 1 comprises two semicircular ring shutoff pipes 3, institute is so that be installed on line; When annular blocking device 1 and ring seal device 2 covers are fixed on behind the line hole; Prick an aperture to ring seal device 2, because said ring seal device 2 is set to vacuum packaging, so make its inflation to seal after pricking the hole into and out of the line hole; The effect of can reach dustproof, anti-bird, protecting line is effectively protected power circuit, easy to use.
