As shown in fig. 1 to 8, the present invention provides a detection processing apparatus for ice coating on a power transmission line, including a first actuator 1 and a second actuator 2 both connected to a plurality of power transmission lines, wherein the second actuator 2 is disposed on a movement path of the first actuator 1, and the first actuator 1 and the second actuator 2 are electrically connected through a wire;
the first actuator 1 includes:
the shaping mechanism 3 is sleeved on each power transmission line and is used for cutting the ice coated on the power transmission line into a specified shape along the circumferential direction, and a torque groove is formed in the surface of the specified shape along the axial direction;

and a polygonal case B11 for mounting the ice breaking mechanism 4 and the displacement generating mechanism 6.
The specific basic reference structure of the first actuator 1 and the second actuator 2 is a spacer bar used for connecting a plurality of power transmission lines (four power transmission lines are taken as an example in the invention) of a high-voltage power transmission line in the prior art, the first actuator 1 and the second actuator 2 are connected with a power supply through a lead for supplying power, and the lead can be designed into a retractable paying-off mode and used for following the movement of the first actuator 1 and the second actuator 2 on the power transmission lines.
Because in remote and high mountain area, it is comparatively difficult to erect transmission line to also be a difficult problem in the maintenance of the transmission line in later stage, heavy low temperature, sleet, freezing calamity weather often make remote area and mountain area cause large tracts of land spatial grid structure to receive heavy destruction, because road conditions and the environmental constraint in remote area and mountain area, the staff can't frequent maintain the line and clear up the icing of transmission line, especially on striding over the topography, for this:
the first actuating mechanism 1 and the second actuating mechanism 2 are electrically connected through a conducting wire, the first actuating mechanism 1 comprises a shaping mechanism 3 and a vibration generating mechanism 5, and the second actuating mechanism comprises an ice breaking mechanism 4 and a displacement generating mechanism 6.
Under the action of multiple factors of rime, wind power and gravity, ice coating on the surface of a power transmission line is not in a regular shape, the existing ice coating deicing mode of the power transmission line comprises thermal deicing and mechanical deicing, the thermal deicing needs to enable the power transmission line to be in an inoperative state, and overload current is applied to enable the power transmission line to heat and further realize deicing.
In the mode of knocking and vibrating mechanical deicing, most of the existing travelling trolleys for mechanical deicing adopt a plurality of groups of rollers to be combined with the power transmission line, the rollers and the power transmission line can derail under high-frequency mechanical vibration, and meanwhile, under the condition of ice coating on the surface of the power transmission line, the sliding friction force between the rollers and the power transmission line is small, and the effective travelling of the rollers can be influenced;
furthermore, in the mode of generating high-frequency vibration, because the length of the power transmission line is long, the conduction of the vibration wave of the vibration source on the power transmission line can be weakened, and therefore:
the invention is mainly realized by the following two aspects in the aspect of processing the ice coating of the power transmission line:
firstly, the ice coating on the power transmission line is cut into a designated shape through the shaping mechanism 3, namely, irregular ice coating formed on the power transmission line is cut into a regular cylinder shape sleeved on the power transmission line through the shaping mechanism 3, a torque groove is formed in the surface of the cylindrical ice coating along the axial direction, the ice breaking mechanism 4 is used for applying tangential torque force to the torque groove, the torque groove is formed to provide a force application point for the ice breaking mechanism 4, and then the cylindrical ice coating is cut.
Secondly, the vibration generating mechanism 5 is used for generating high-frequency vibration on the plurality of power transmission lines, the displacement generating mechanism 6 is used for driving the plurality of power transmission lines to generate periodic centripetal movement while the vibration generating mechanism 5 drives the power transmission lines to generate the high-frequency vibration, the displacement generating mechanism 6 generates the centripetal movement of the power transmission lines to form a breakpoint of vibration transmission of the vibration generating mechanism 5 on the power transmission lines, and the high-frequency vibration of the power transmission lines is intercepted on the power transmission lines between the vibration generating mechanism 5 and the displacement generating mechanism 6.
The existing method for removing the ice coating by using high-frequency vibration has the advantages that the bonding structure between the interior of the ice coating and a power transmission line is compact, so that the ice coating cannot be removed effectively by using simple high-frequency vibration, and the energy dissipation of the high-frequency vibration in the transmission process is very obvious.
The working principle of the vibration generating mechanism 5 and the displacement generating mechanism 6 in the invention is that under the action of the spacers of the first actuating mechanism 1 and the second actuating mechanism 2, the distances between a plurality of power transmission lines are the same, and under the influence of the gravity of the power transmission lines, the first actuating mechanism 1 and the second actuating mechanism 2 have a height difference, and along with the increase of the distance between the first actuating mechanism 1 and the second actuating mechanism 2, the second actuating mechanism 2 is positioned in a low potential energy area, the influence of wind power and air temperature on the position is the largest, and the dynamic representation of the power transmission lines is more obvious.
Therefore, when the vibration generating mechanism 5 generates high-frequency vibration, the displacement generating mechanism 6 pulls a plurality of power transmission lines centripetally in a low potential energy area, and the effect is that the displacement generating mechanism 6 applies radial tension to a certain position of the power transmission lines, so that the high-frequency vibration generated by the vibration generating mechanism 5 is counteracted or weakened when reaching the position of the displacement generating mechanism 6, and the counteraction or weakening can quickly feed back the high-frequency vibration along the power transmission lines, so that the surface stress of the power transmission lines between the vibration generating mechanism 5 and the displacement generating mechanism 6 is increased, and the effect of the vibration generating mechanism 5 on the power transmission lines is further improved;
meanwhile, the overhead transmission line swings under the action of gravity and wind force, and the swing has more influence factors in the actual process, the analysis of a typical icing guide-crescent icing conductor aerodynamic characteristic analysis model based on the fluid mechanics theory is utilized to obtain that four transmission lines are pulled by a displacement generating mechanism 6, the line at the position is in a tight state by the pulling force of the iron tower of the transmission line on the transmission line, and the gravity at the position of the transmission line is downward, so that a plurality of transmission lines can generate certain self-rotating rotation at the geometric center of the displacement generating mechanism 6 when the transmission line is subjected to wind force of any attack angle, and at the moment, the vibration generating mechanism 5 is relatively close to the self-rotating rotation of the transmission line and is not obvious enough or self-rotating, so the vibration generating mechanism 5 and the displacement generating mechanism 6 act under the action and the limitation, the stress generated on the transmission line will break the ice coating on the transmission line from the bonding surface of the ice coating and the transmission line.
