Embodiment Construction
[0023] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.
[0024] This embodiment proposes a high-voltage transmission line deicer, such as figure 1 and 2 As shown, it includes a back plate 1, a first connecting rod 2, a second connecting rod 3, a third connecting rod 4, a hammer body 5, a first elastic element 6, an arc-shaped slot 7, a pin 8, a lifting motor 9, a first Two rollers 10, first roller 11, fixed shaft 12, linear motor 14, cam 15, rotating motor 16, second elastic element 17, second contact sensor 18, first contact sensor 19, shifting block 20.
[0025] Wherein the first roller 11 and the second roller 10 are arranged up and down, and both are arranged on the front of the backboard 1 , the number of the first ro...

The invention provides a high-voltage transmission line deicer, which comprises: a back plate and a first connecting rod which are rotatably connected; a second connecting rod, wherein one end of thesecond connecting rod is rotationally connected with one end of the first connecting rod, and the other end is provided with a hammer body; an arc-shaped through groove formed in the back plate, wherein the track point of the arc-shaped through groove is gradually close to the second connecting rod from bottom to top; and a rotating block mounted on the back plate and used for driving the end portion of the first connecting rod to move along the arc-shaped through groove. According to the invention, the high-voltage transmission line deicer is different from the prior art, an operation mode that a traditional mechanical deicer scrapes an icing layer is changed into a hammering mode, the icing layer attached to the electric wire is effectively and rapidly knocked out, the high-voltage transmission line deicer can be suitable for most occasions, the walking mechanism can effectively abut against the back of the electric wire section during knocking, and the force of knocking the ice hammer can completely act on the ice layer.
Description
technical field [0001] The invention relates to the field of machinery, in particular to a deicer for high-voltage transmission lines. Background technique [0002] Because high-voltage transmission lines are generally erected at high altitudes, some areas in northern and southern my country are very cold in winter, and some areas have icing on overhead power transmission lines due to specific meteorological reasons. When the ice layer reaches a certain thickness, it must be removed, otherwise it will cause the power line to be broken and cause a power outage, seriously affecting industrial production and life. [0003] In the prior art, in order to solve this problem, there are mainly three kinds of deicing methods, electric heating deicing, manual deicing and mechanical deicing. in: [0004] First of all, the principle of electrothermal ice melting is to short-circuit the user end of the transmission line, reduce the power supply voltage through a step-down transformer, ...
