Description

Technical Field

[0001] The present invention relates to a de-icing device, specifically a cable de-icing device. Background Art

[0002] Snow and ice accumulation on overhead transmission lines is one of the most serious natural disasters faced by the power system. After the transmission line is covered with ice, the load increases, the unbalanced tension of the line becomes larger, which easily leads to accidents such as broken wires and broken strands of the line, and tower overturning, seriously affecting the operation safety of the transmission line.

[0003] In existing de-icing methods, including natural de-icing, thermal de-icing, robot de-icing and other methods. The natural de-icing method is to install devices such as snow blocking rings, balance weights and wire clamps on the power line to achieve the purpose of de-icing.

[0023] The present invention will be described in more detail with reference to the accompanying drawings as follows:

[0024] Combined with Figure 1-8 , an ice removal device for high-voltage power lines of the present invention includes a traveling mechanism 100, the traveling mechanism 100 has an upper sheave 101, a connecting rod 102, a driving motor 103, a lifting ring 104, a moving rod 105, a spring 106, a fixed rod 107, a driving gear 108 and an ice removal gear 109. One end of the upper sheave 101 is fixed on the connecting rod 102 through a bearing and is meshingly driven by the driving motor 103. The driving motor 103 is fixed on the connecting rod 102. The ice removal gears 109 are respectively installed on the moving rod 105 and the fixed rod 107. The lifting ring 104 is fixed on the moving rod 105. One end of the spring 106 is connected to the lifting ring 104 and the other end is connected to the fixed rod 107.

[0025] The ice removal device for high-voltage power lines further includes a support assembly 200. The support assembly 200 is located on the box body 300. The support assembly 200 includes a lower sheave 201, a curved rod 202 and a support push rod 203. One end of the lower sheave 201 is fixed on the curved rod 202, and the lower end of the curved rod 202 is fixed on the support push rod.

[0026] The ice removal device for high-voltage power lines further includes a box body 300. The box body 300 includes a box body main body 301, a box body upper cover 302, a bracket 303, a base 304, a controller 305 and a battery 306. The controller 305 and the battery 306 are placed in the box body main body 301. The bracket 303 is fixed in the middle of the box body main body 301. The base 304 is fixed on the bracket 303. The box body upper cover 302 is installed on the box body main body 301.

[0027] The ice removal gear 109 is in the shape of a bevel gear with the tip downward, and the ice removal gear 109 is installed by meshing with the gear at the end of the output shaft of the second motor through the driving gear 108.

[0028] The lifting ring 104 connects the movable rod 105, the spring 106 and the fixed rod 107 to realize the movement of the movable rod 105.

[0029] There is a groove on the end face of the upper sheave 101, and an internal gear ring is fixed inside and is meshingly connected with the output shaft of the driving motor 103.

[0030] The telescopic rod 203 and the upper sheave 101 are in the same vertical plane, and the upper sheave 101 and the lower sheave 201 are also in the same vertical plane.

[0031] The telescopic rod 203 is fixed on the base 304, passes through the upper cover 302 of the box body and extends out of the box body 300, and is connected to the controller 305 and the power supply 306.

[0032] The driving motor 103 drives the upper sheave 101. The rotation of the upper sheave 101 drives the device to move back and forth. The high-voltage cable de-icing device further includes a support mechanism 200. The support mechanism 200 includes a lower sheave 201, a bending rod 202, and a support push rod 203. After the support push rod 203 is energized, it elongates, so that the upper part of the lower sheave 201 contacts the cable. The upper sheave 101 and the lower sheave 201 clamp and walk on the cable. The box body 300 includes a box body main body 301. The controller 305 and the battery 306 are fixedly installed inside the box body main body 301. The bracket 303 is fixedly installed in the middle of the box body main body 301 and is placed upward. The base 304 is fixedly installed in the middle of the bracket 303. The upper part of the base 304 is fixedly connected to the support push rod 203 to play a role of fixed support. After the support push rod 203 is energized and elongates, the upper roller 101 and the lower roller 201 clamp the cable to complete the fixation. In this example, in order to ensure that the entire device is firmly connected to the cable to be de-iced, two upper rollers 101 are used to balance the acting force.

[0033] During de-icing, first place the upper roller 101 of the device on the cable, and then the controller 305 controls the support push rod 203 to be energized and elongate, so that the lower roller 201 rises and contacts the ice surface on the cable, and clamps the cable together with the upper roller 101 to complete the firm fixation. At this time, through the stretching action of the lifting ring 104 and the spring 106, the movable rod 105 is controlled to automatically move the angle, so that the de-icing gear 109 finds a suitable position, contacts the ice on the cable and is pressed tightly on the surface of the ice at the same time. Then the controller 305 controls the driving motor 103 to start. The output end of the driving motor 103 rotates to drive the meshing-connected upper sheave 101 to rotate, so that the entire device moves forward. At the same time, the output end of the second driving motor 103 drives the driving gear 108 to rotate, and then drives the de-icing gear 109 to rotate to roll and de-ice the ice on the cable. By reasonably arranging the relative positions of the gaps between the two de-icing gears 109, damage to the cable surface caused by the de-icing gear 109 after de-icing is prevented. During the forward movement, the de-icing gear 109 presses on the new ice surface to roll and crush the ice, and so on, to complete the entire automatic de-icing process.
