Description of drawings
Fig. 1 is the structural representation of the described six division power transmission line intelligent deicers of embodiment.
Embodiment
Describe below in conjunction with accompanying drawing and specific embodiment.
Six division power transmission line intelligent deicers described in the utility model comprise a substrate 1, and the shape of this substrate can be the center of circle, can be also rectangle, and for ease of describing, the present embodiment is selected rectangular substrate.
Fig. 1 shows six division power transmission line intelligent deicers described in the present embodiment.The center of substrate 1 is installed with a central shaft 11, is provided with two hook sections 12 on one group of diagonal angle of this substrate, and this hook section 12 for hook or hole, is mainly to provide a fixed connection point for marmem 3.Further, described two hook sections 12 are positioned on a diagonal of substrate 1, certainly, can be near this be cornerwise the position.Here said angle, be not a point, but a zone.
Symmetrical structure centered by special-shaped cam 2 is installed on substrate 1, comprise two long-armed 21 and two galianconism 22.Arm section long-armed and disconnected arm is cambered surface.The center of this abnormal shape cam 2 is provided with an installing hole, and described central shaft 11 is rotatably assorted with described installing hole.Long-armed 21 are connected with marmem 3, and marmem 3 is connected with the hook portion of substrate 1 again.This marmem is bar shaped.Before marmem 3 temperature influences distortion, long-armed 21 are positioned on another group diagonal angle of substrate 1.Long-armed 21 and hook section 12 between sufficient distance is arranged, satisfy the stroke requirement of shape memory alloy deformation, make six division power transmission line intelligent deicers start the deicing programs.
Two arc T shape connecting rods 4 also are installed on substrate 1, arc T shape connecting rod 4 comprises an arc and a straightway, limit sliding chutes 13 on its straightway and substrate 1 is slidably matched, straightway one end connects in the middle part of arc, the straightway other end is provided with a roller 41, roller 41 consists of a higher pair mechanism with special-shaped cam 2, and the two ends of its segmental arc and middle part are respectively arranged with wire fixing hole 42.According to effect and the purposes of six division power transmission line intelligent deicers, radian and the arc length of the arc of arc T shape connecting rod 4 are determined by the distance of transmission pressure.Arc T shape connecting rod 4 has also played the effect of conductor spacer.When six division power transmission line intelligent deicers was installed, this device was positioned in the middle of six division power transmission lines, and the wire fixing hole that passes through two arc T shape connecting rods 4 of six division power transmission line intelligent deicers is fixed wire.In mounted six division power transmission line intelligent deicers, the straightway of two arc T shape connecting rods 4 is parallel with horizontal plane.
Resonance device 5 also is installed on substrate 1, and described resonance device has spring and gravity block to consist of, and an end of spring is fixed on substrate 1, and the other end is fixedly connected with gravity block.Spring is vertical with horizontal plane, and when six division power transmission line intelligent deicer vibrations, resonance device 5 could be to the six larger shaking forces of division power transmission line intelligent deicer like this.
The variation of ambient temperature and humidity makes the contraction in length of marmem 3, pulls simultaneously special-shaped cam 2 to make its rotation.Along with the rotation of cam 2, the T-shaped connecting rod 4 of arc traveling priority under the restriction of limit sliding chutes 13.Along with special-shaped cam 2 constantly rotates along a direction such as clockwise direction, the T-shaped connecting rod 4 of arc supports six-multiple conductor, and the spacing between wire is separated from each other, and wire increases gradually to the reaction force of the T-shaped connecting rod 4 of arc.Along with the rotation of special-shaped cam 2, roller 41 arrives the arm end of galianconism 22, between six-multiple conductor 6 between from reaching maximum.Special-shaped cam 2 is rotated further, roller 41 slips over the arm end of galianconism 22, at this moment, the T-shaped connecting rod 4 of arc drives wire and accelerates suddenly to return, the power that this great acceleration produces makes wire generation strenuous vibration, be resonance device 5 vibrations simultaneously, resonance device 5 vibrations make all that wire constantly shakes, thereby have just stoped icing pile up or make coating ice falling on wire in the continuation on wire.
Be below only preferred implementation of the present utility model, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection range of the present utility model should be as the criterion with the claim limited range.For those skilled in the art, within not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
