A heating box 8 is fixedly connected to the outside of one of the fixed blocks 7, and a mounting cylinder 9 is fixedly connected to the outside of the other fixed block 7. A conduit 22 is fixedly connected to one side of the mounting cylinder 9, and a conduit 11 is fixedly connected to the other side of the mounting cylinder 9. The other end of the conduit 11 is fixedly connected to the injection component 10.

A heating component is installed inside the placement box 1.

[0032] Furthermore, first start the motor 4, the output end of the motor 4 drives the bidirectional threaded rod 5 to rotate, and then under the action of the bidirectional threaded rod 5, the two extrusion blocks 2 are moved closer to each other along the inner wall of the connecting column 20, and then drive the extrusion rollers 6 to move closer to each other, so that the two extrusion rollers 6 squeeze the ice layer on the outside of the cable body 3, and start the motor 2 17, the output end of the motor 2 17 drives one of the gears 19 to rotate, and then the gear 19 drives the other gear 19 to rotate at the same time through meshing, so that the two wheels 12 rotate towards each other at the same time, and the deicing device is driven by the two wheels 12 to move forward along the cable body 3, so that the two extrusion rollers 6 rotate, and then the outside of the cable body 3 is squeezed and de-iced, and the ice and snow on the cable surface can be effectively removed by extrusion deicing, ensuring the normal operation and safe use of the cable, and reducing the risk of electrical accidents.

[0033] Reference Figure 2 and Figure 3The heating component includes a motor 4, which is fixedly connected to the inner wall of the placement box 1. The inner wall of the placement box 1 is fixedly connected with a connecting column 20, and the inner wall of the connecting column 20 is rotatably connected with a bidirectional threaded rod 5. The external threads of the bidirectional threaded rod 5 are connected to two extrusion blocks 2. The outside of the extrusion block 2 is provided with a groove, and the inner wall of the groove is rotatably connected with an extrusion roller 6.

The inner wall of the placement box 1 is fixedly connected with a support rod 16.

[0034] Furthermore, in addition, air is transported to the interior of the heating box 8 by the blower, and then the air is heated by the electric heating wire. Under the action of the belt, the synchronous wheel 18 and the synchronous wheel 26 rotate at the same time, and the synchronous wheel 26 drives the turntable 27 to rotate, and then drives the transmission member 29 to rotate. At this time, the transmission member 29 drives the annular member 28 to slide along the outer side of the turntable 27, and the annular member 28 drives the moving rod 21 to move. One of the moving rods 21 drives the piston 24 to move at the same time. When the moving rod 21 pulls the piston 24 outward, the one-way valve 1 23 opens, and the one-way valve 2 opens. When the piston 24 is pushed inward by the movable rod 21, the one-way valve 23 is closed and the one-way valve 25 is opened, and the hot air enters the interior of the jet component 10 through the conduit 11 and is then sprayed onto the surface of the cable body 3 to melt the residual ice layer with the hot air, thereby further improving the deicing efficiency of the deicing device. At the same time, the water stains on the surface of the cable body 3 after melting are adsorbed by the sponge block 14 to remove the residual water stains, thereby extending the service life of the cable and improving the reliability and stability of the equipment.

[0035] Reference Figure 2 and Figure 3 The outside of the heating box 8 is fixedly connected with a blower, the inner wall of the heating box 8 is fixedly connected with a heating wire, and the end of the conduit 22 away from the mounting tube 9 is connected to the outside of the heating box 8.

[0036] Furthermore, the blower draws external air into the heating box 8, and then heats the air through the heating wire. The heated air is transported to the inside of the installation tube 9 through the second pipe 22, and the hot air melts the residual ice layer on the surface of the cable body 3, thereby improving the deicing efficiency of the deicing device.

[0037] Reference Figure 3 and Figure 5 The outside of the transmission member 29 is slidably connected to the inner wall of the ring member 28, one end of one moving rod 21 away from the ring member 28 is slidably connected to the outside of the fixed block 215, and the other end of the moving rod 21 away from the ring member 28 is fixedly connected to the outer side of the piston 24.

[0038] Furthermore, when the transmission member 29 rotates, the annular member 28 slides along the outside of the rotating disk 27, so that one of the moving rods 21 drives the piston 24 to reciprocate, and the other moving rod 21 functions to limit the annular member 28 to prevent the annular member 28 from deflecting when moving.

[0039] Reference Figure 2 and Figure 3 The outside of the support rod 16 is rotatably connected to another gear 19 , and the outside of the gear 19 is fixedly connected to another rotating wheel 12 .

[0040] Furthermore, the deicing device moves along the surface of the cable body 3 through the cooperation between the two gears 19 and the two rotating wheels 12 .

[0041] Reference Figure 3 , the outside of one gear 19 is meshed and connected with the outside of another gear 19 at the corresponding position.

[0042] Furthermore, one of the gears 19 drives the other gear 19 to rotate through meshing, thereby causing the two wheels 12 to rotate towards each other, thereby ensuring the effectiveness of the structure.

[0043] Reference Figure 3 The outer side of the synchronous wheel 18 is connected to the outer side of the synchronous wheel 26 through a belt.

[0044] Furthermore, when the synchronous wheel 18 rotates, under the action of the belt, the synchronous wheel 18 and the synchronous wheel 2 26 rotate simultaneously.

[0045] Reference Figure 1 and Figure 2 The outer portion of the extrusion block 2 fits with the inner wall of the connecting column 20 .

[0046] Furthermore, when the bidirectional threaded rod 5 rotates, the extrusion block 2 is limited by the connecting column 20 , so that the extrusion block 2 slides along the inner wall of the connecting column 20 .

[0047] Working principle: First, start the motor 1 4. The output end of the motor 1 4 drives the bidirectional threaded rod 5 to rotate, and then the bidirectional threaded rod 5 drives the two extrusion blocks 2 to approach each other along the inner wall of the connecting column 20, and then drives the extrusion rollers 6 to approach each other, so that the two extrusion rollers 6 fit the cable body 3. Start the motor 2 17. The output end of the motor 2 17 drives one of the gears 19 to rotate, and then under the meshing action of the two gears 19, the two wheels 12 rotate in opposite directions, and the deicing device is driven by the two wheels 12 to move forward along the cable body 3, so that the two extrusion rollers 6 rotate while moving, and then the outside of the cable body 3 is squeezed and de-iced. Deicing by extrusion is more efficient and economical, saving time and energy for maintenance personnel.

[0048] In addition, air is transported to the interior of the heating box 8 by the blower, and then the air is heated by the electric heating wire. Under the action of the belt, the synchronous wheel 18 and the synchronous wheel 26 rotate at the same time, the synchronous wheel 26 drives the turntable 27 to rotate, the turntable 27 drives the annular member 28 to slide through the transmission member 29, and the annular member 28 drives the moving rod 21 to move, and one of the moving rods 21 drives the piston 24 to move at the same time. When the moving rod 21 pulls the piston 24 outward, the one-way valve 1 23 opens, the one-way valve 25 closes, and the hot air inside the heating box 8 passes through Conduit No. 22 enters the interior of the mounting tube 9. When the moving rod 21 pushes the piston 24 inward, the one-way valve No. 1 23 is closed and the one-way valve No. 2 25 is opened. The hot air enters the interior of the jet component 10 through the conduit No. 11 and is then sprayed onto the surface of the cable body 3 to melt the residual ice layer with the hot air, thereby further improving the de-icing efficiency of the de-icing device. At the same time, the melted water stains are adsorbed by the sponge block 14 to prevent the water stains from condensing into ice again in a low temperature environment, thereby further improving the de-icing efficiency and reducing the safety hazards caused by residual water stains.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
