Since the first half cylinder 18 is connected to the first support plate 33 by the third electric push rod 27 and the second half cylinder 19 is connected to the second support plate 34 by the second electric push rod 24, the first support plate 33 and the second support plate 34 can be synchronized with each other with respect to the first half cylinder 18 and the second half cylinder 19, respectively.
When the water absorption pad 25 is filled with snow water or rainwater, the wiping effect of the water absorption pad 25 on the cable surface is reduced, the snow water or rainwater in the water absorption pad 25 needs to be squeezed out, at this time, the third electric push rod 27 and the fourth electric push rod 28 are started to shorten the third electric push rod 27 and the fourth electric push rod 28, and along with the shortening of the third electric push rod 27, the first water squeezing rod 29 is sequentially inserted into the first water squeezing hole 18-2 and the accommodating cavity 26 of the first semi-cylinder 18 to squeeze the water absorption pad 25 in the first semi-cylinder 18, so that the snow water or rainwater absorbed by the water absorption pad 25 in the first semi-cylinder 18 is squeezed out; with the shortening of the fourth electric push rod 28, the second wringing rod 30 is inserted into the second wringing hole 19-2 and the accommodating cavity 26 of the second half cylinder 19 in sequence, so that the water absorption pad 25 in the second half cylinder 19 is squeezed, and snow water or rainwater absorbed by the water absorption pad 25 in the second half cylinder 19 is squeezed out. The squeezed snow water or rain water flows out from the gap between the first half cylinder 18 and the second half cylinder 19.
Continuing to start the third electric push rod 27 and the fourth electric push rod 28, so that the third electric push rod 27 and the fourth electric push rod 28 are both extended, and as the third electric push rod 27 is extended, the first wringing rod 29 sequentially comes out of the accommodating cavity 26 and the first wringing hole 18-2 of the first half cylinder 18, so that the absorbent pad 25 in the accommodating cavity 26 of the first half cylinder 18 is loosened again and restored to the original state; with the extension of the fourth electric push rod 28, the second wringing rod 30 comes out from the containing cavity 26 of the second half cylinder 19 and the second wringing hole 19-2 in sequence, so that the absorbent pad 25 in the containing cavity 26 of the second half cylinder 19 is released again and recovered. Finally, the third electric putter 27 and the fourth electric putter 28 are closed.
The water absorption effect of the water absorption pad 25 after being squeezed is improved, and snow water or rainwater on the cable can be continuously wiped.
In order to ensure the electrical insulation of the overhead cable maintenance device of this embodiment 2, the surfaces of the third electric push rod 27, the fourth electric push rod 28, the first wringing rod 29, the second wringing rod 30, the first support plate 33, and the second support plate 34 are all coated with an insulating material.
Known through the above-mentioned use, the high altitude cable maintenance device of this embodiment 2 can extrude the pad 25 that absorbs water that is located and holds chamber 26, extrudes the rainwater or the snow water that the pad 25 absorbed that absorbs water, has realized the reuse of the pad 25 that absorbs water, has guaranteed the effect of cleaning of the pad 25 that absorbs water to the cable.
As shown in fig. 2, in order to improve the drainage efficiency of the absorbent pad 25, the first half cylinder 18 and the second half cylinder 19 are provided with the drainage holes 32, so that the rainwater or snow water extruded from the absorbent pad 25 can flow out from the gap between the first half cylinder 18 and the second half cylinder 19, and the extruded snow water or rainwater can flow out from the drainage holes 32, thereby improving the drainage efficiency of the absorbent pad 25 and improving the wiping efficiency of the cable.
Example 3:
As shown in fig. 1 or fig. 3, the end of the first supporting plate 33 away from the first half-cylinder 18 and the end of the second supporting plate 34 away from the second half-cylinder 19 are both welded and fixed with heating elements, in this embodiment 3, the heating elements are electric heating plates 31, and the surfaces of the electric heating plates 31 are coated with insulating paint.
Because the length of the cable is long and can reach 2 kilometers, in the process that the shell moves along with the transmission belt 6 and the water absorption pad 25 wipes the cable, a layer of ice is wrapped on the cable which is not wiped by the water absorption pad 25, so when the water absorption pad 25 wipes the frozen cable, the wiping effect of the water absorption pad 25 on the cable is reduced, and for this purpose, in the process that the shell moves along with the transmission belt 6, the electric heating plate 31 needs to be started, and the electric heating plate 31 melts the unmelted snow in advance and melts the ice wrapped on the cable, so that the wiping effect of the water absorption pad 25 on the cable is ensured.
After snow and ice are melted, the water absorption pad 25 can conveniently wipe the cable, the phenomenon that the ice layer obstructs the movement of the shell can be avoided, and the electric heating plate 31 also plays a role in removing obstacles.
Moreover, the heat of the electric heating plate 31 can prevent the water absorption pad 25 from freezing, and the wiping effect of the water absorption pad 25 on the cable is also ensured.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
