Description

Cable deicing mechanism

Technical field:

The utility model relates to a kind of cable deicing mechanism, is particularly useful for the deicing of high-tension cable.

Background technology:

For electric power system, rainproof coating waits the influence that prevents and alleviate sleet although can be coated with by ice-melt with on cable, but for more serious sleet disaster, these methods or consume energy hugely, or DeGrain is through contrast, the heating power deicing method can loss-rate mechanical deicing method exceed more than 100 times, for utilizing mechanical shock to open ice, even its deicing efficiency is low to moderate 3%, its effect is still high 30～100 times than heating means in addition.

Because the harshness of environment, at present, the means of artificial and wooden stick are taked in domestic deicing to cable and electric tower more, and not only efficient is low for this deicing mode, and what is more important is greatly dangerous.

Summary of the invention:

The purpose of this utility model provides a kind of cable deicing mechanism of avoiding the danger of artificial deicing and improving deicing efficiency.

Above-mentioned purpose realizes by following technical scheme:

Cable deicing mechanism, its composition comprises: weight, described weight is connected with fork by leaf spring, described fork is connected by revolute pair with frame, described fork by the chute on it be fixed on the hinged pinion of frame on finger constitute higher pair, the engagement of described pinion and gear wheel, described gear wheel be installed in the hinged driving shaft of frame on, motor is fixed on the described frame;

Running roller I sky is enclosed within on the rolling axle I that is connected by chute with described frame, described running roller I is pressed on the cable that removed ice that is arranged in the driving shaft V-shaped groove, passive bye is enclosed within on the passive wheel shaft that is connected with described frame, running roller II sky is enclosed within on the rolling axle II that is connected by chute with described frame, the two ends of described rolling axle II are connected with the two ends of described passive wheel shaft by spring respectively, and described running roller II is pressed in be arranged in the driving shaft V-shaped groove described and removed on the cable of ice.

Described cable deicing mechanism, described frame comprise side plate, quadruplet screw, nut 21 and support set, described weight by pouring weight with knock piece and connect to form, described revolute pair is enclosed within the gear fixed axis and the side plate that are fixed on the side plate by the pinion sky and constitutes.

Described cable deicing mechanism, described pinion, described fork, described leaf spring and described weight have two cover symmetries and install, described two pinion of while, and described driving shaft is hinged by two rolling bearings and frame.

The beneficial effects of the utility model:

1. the utility model can be used as the automatic de-icing instrument of aerial high-voltage cable, has avoided the danger that brought by artificial deicing, improves deicing efficiency simultaneously, and this apparatus structure is simple, and deicing is effective.

2. weight is connected with fork by leaf spring in the utility model, and leaf spring plays the absorption weight and knocks the vibrations that ice slush brings, thus the body of protection cable deicing mechanism.Weight can increase the knock dynamics of weight to ice slush by the accumulation of energy of leaf spring and the effect that releases energy simultaneously.

3. the utility model middle roll II will be pressed on the driving shaft that has V-shaped groove except that the cable of crossing ice by the effect of spring, by the frictional force drives cable and the deicing mechanism relative motion of cable and V-shaped groove, make and can carry out continuously the deicing of cable.Running roller II will be pressed on the follower that has V-shaped groove except that the cable of crossing ice by the effect of spring simultaneously, play the effect of setting upright cable or deicing mechanism.
