Abstract
The utility model belongs to the field of alarming equipment, and particularly relates to a power transmission line windproof alarm. The power transmission line windproof alarm is structurally characterized in that a main fixing ring and two auxiliary fixing rings are fixedly connected above a fixing frame, a current transformer for extracting power is arranged inside the main fixing ring, an inverted 'T'-shaped connecting rod is fixedly connected under the fixing frame, and a bearing free of maintenance and an alarm fixedly connected with an outer ring of the bearing free of maintenance are sleeved onto the connecting rod. When in the wind, wind power drives the alarm to rotate along the connecting rod, thereby effectively reducing action force of the alarm to power transmission lines, reducing abrasion of the power transmission line and having windproof effect. In addition, the power transmission line windproof alarm is simple in structure, convenient in mounting and low in cost.
Description
Technical field
The utility model belongs to the caution apparatus field, the windproof attention device of particularly a kind of transmission line of electricity.
Background technology
All the time, truck crane, forklift etc. some need be in the building site etc. the vehicle of place operation and equipment etc. all exist the potential safety hazard that accident is touched electric line, the accident that causes car crash therefrom happens occasionally, and may cause power failure, cut off the water, harm such as traffic jam and delayed works.Accident has a strong impact on electrical production and construction safety, threatens broken string field staff's life security.The height of domestic shaft tower is the highest to have reached 110 meters, and this has also caused certain threat to transatmospheric vehicle, alarming device need be installed to reduce or to avoid the generation of accident on transmission line of electricity.
Some alarming devices have been used in more domestic areas successively, mostly be rectangular shape greatly, played certain warning function, but also there are not report or introduction about the alarming device of windproof performance, in typhoon or strong wind area, can constantly swing the power transmission line that weares and teares because of alarming device, thereby may cause transmission line of electricity broken string accident, cause serious consequence and massive losses.
Summary of the invention
The utility model provides a kind of transmission line of electricity windproof attention device at the situation of existing caution equipment protection effect difference.
The technical scheme that adopts is: the fixed mount affixed main set collar in top and 2 secondary set collars are used for attention device is fixed in electric wire; Being provided with current transformer in the main set collar, being used for power taking from the power transmission line, is self circuit board power supply; The affixed inverted "T"-shaped connecting rod in the below of fixed mount; Connecting rod has cable-through hole, is with non-maintaining bearing on the connecting rod, and the attention device affixed with non-maintaining bearing outer ring.
Described attention device is rectangular parallelepiped, right cylinder, hemisphere, spheroid or other polyhedrons.
Described connecting rod also is " worker " font, inverted " Y " font or other shapes that can accept rolling bearing and not influence the rolling bearing rotation.
The beneficial effects of the utility model are: in typhoon or strong wind area, this device can rotate under the effect of wind-force, effectively reduces attention device because swing to the wearing and tearing of power transmission line, reduces the acting force of wind-force to attention device, and good protection effect is arranged; Simple in structure, easy for installation, cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Number in the figure:
The 1-fixed mount; 2-master's set collar; The secondary set collar of 3-; The 4-connecting rod; The 5-rolling bearing; The 6-attention device; The 7-power transmission line; The 8-current transformer.
Embodiment
The utility model provides a kind of transmission line of electricity windproof attention device, below by description of drawings and embodiment the utility model is described further.
Fig. 1 is a structural representation of the present utility model.The affixed main set collar 2 in fixed mount 1 top and 2 secondary set collars 3 are used for being connected with power transmission line 7; In the main set collar 2 current transformer 8 being installed, being used for power taking from the power transmission line 7, is self circuit board power supply.The affixed inverted "T"-shaped connecting rod 4 in the below of fixed mount 1, connecting rod 4 middle parts are left and are used for the hole that lead passes; Be with rolling bearing 5 on the connecting rod 4, and the attention device 6 affixed with rolling bearing 5 outer rings.Attention device 6 is a rectangular parallelepiped, surface distribution warning lamp.
When wind was arranged, wind-force promoted attention device 6 and rotates around connecting rod 4, has effectively reduced the acting force of 6 pairs of power transmission lines 7 of attention device, has reduced the wearing and tearing of power transmission line 7, has played windproof effect.
Proof by experiment, when attention device 6 was right cylinder, hemisphere or spheroid, this device had good windbreak function equally.
