Problems solved by technology

[0003] At present, the commonly used device for cleaning foreign objects in the line inspection and maintenance work of transmission lines is as disclosed in Chinese invention patent CN201410792342.1, which installs the cleaning part on the front end of the equipment. Patent CN201520451624.5 has a structure in which the cleaning part is installed at both ends of the equipment. In the above two structures, the driving part is set at the rear or middle of the overall equipment, and the cleaning part is equivalent to a cantilever hanging outside the driving part (fixed end) Beam structure, when the nodules on the transmission line are hard, and the cleaning part and the nodules vibrate due to friction, the cantilever beam structure will shake, and the cleaning part is easy to directly collide with the transmission line, causing the transmission line to be scratched or even broken. secondary disaster

specific Embodiment 1

[0025] Specific embodiment 1, such as figure 1 and figure 2 and image 3 As shown, the present invention is a power transmission line cleaning device, which is attached to the power transmission cable and moves along the power transmission cable. The cleaning part includes a casing 1 with a cylindrical structure and a cleaning device arranged in the casing 1. The driving part includes a set of driving wheels symmetrically arranged at both ends of the casing 1. The cleaning device is installed on the driving wheels at both ends. between the wheels. When the present invention is working, power is provided by means of the drive wheels on the front and rear sides, so that the device of the present invention has a better forward ability and can smoothly drive through the section of the transmission line that is entangled to form nodules. The staff adopts wired or wireless control. The motor of the driving part rotates or stops, so as to realize the forward, backward or stop of ...

specific Embodiment 2

[0032] Specific embodiment 2, such as figure 1 As shown, two sets of parallel connecting rods 8 are arranged between the driving spindle 2 and the casing 1, and the driving spindle 2, the casing 1, and the two sets of connecting rods 8 form a parallelogram linkage mechanism. At least three groups of driving spindles 2 are respectively provided at both ends of the housing 1 , connecting ears 9 are provided on both sides of the driving spindles 2 , and the connecting ears 9 of adjacent driving spindles 2 are connected by means of limit spring rods 10 . The pulling force of the limit spring rod 10 set is greater than the pulling force of the return spring rod 4. With the help of the pulling effect of the limit spring rod 10 and the parallelogram linkage mechanism, when the diameter of the transmission line for equipment operation is too large due to foreign matter, the return spring rod 4 When it is still unable to pass after being drawn to the limit position, the drafting length...

specific Embodiment 3

[0034] Specific embodiment 3, further, described cleaning device comprises cleaning belt 11, the driving roller 12 that supports cleaning belt 11 rotations and driven roller 13, and described driving roller 12 power is connected with motor, and described cleaning belt 11 Cutter teeth 14 are arranged on the belt surface. The cutter teeth 14 are in a J-shaped structure. With the help of the cleaning belt 11 rotation, the knife teeth 14 can scratch the foreign matter, so that the foreign matter is broken and separated from the power line. The J-shaped knife tooth 14 is set. Opening and cutting, when the hook-shaped part moves backward, it can squeeze and cut foreign objects such as ice, which improves the scope of use of the cleaning device.

Abstract

The invention relates to a power transmission cable cleaning device and belongs to the field of a sweeping maintenance device for a power transmission line. Driving parts are arranged at two ends of ashell and a cleaning device is arranged in the shell, thus the working mode of the invention is that a nodule foreign matter to be cleaned is 'swallowed' into a body, then the foreign matter is cleaned by using a cleaning part, the driving parts arranged at two ends of the shell play the role of positioning, the shaking of equipment is limited, a problem that a cable is scratched caused by the shaking of the cleaning part is avoided, and the safe operation of a transmission cable is ensured.

Description

technical field [0001] The invention belongs to the field of cleaning and maintenance devices for power transmission lines, and in particular relates to a cleaning device for power transmission lines. Background technique [0002] The transmission line is erected in mid-air, and flying plastic bags, kites, balloons and other objects are easy to entangle with the transmission line, which will cause a short-circuit accident of the transmission line and cause great economic losses. The actual line inspection and maintenance work is usually It is carried out according to the shift cycle of the line inspectors, so the foreign matter hanging on the transmission line between the two line inspections may remain for a long time, and the foreign matter is easily entangled on the transmission line under the action of the wind, forming a relatively hard Nodules of foreign bodies are difficult to remove. In addition, the weather in the north is cold in winter, and icing disasters are pr...
