[0002] The transmission line is realized by boosting the electric energy generated by the generator with a transformer and then connecting it to the transmission line through control equipment such as circuit breakers. In terms of structural form, the transmission line is divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, conductors, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. According to the nature of the transmitted current, the transmission is divided into AC transmission and DC transmission.

[0003] At present, during the winter power transmission process of the transmission line, the surface of the transmission line will freeze due to weather reasons. In order to ensure the electricity consumption of residents, it is necessary to melt the ice on the transmission line, so an ice melting device is required. Although the current ice melting device can melt ice during use, during the use process, since the ice on the line generally droops downward, when melting the ice on the line, the drooping ice will block the sliding of the device, affecting the melting speed of the ice. Therefore, a DC ice melting device for transmission lines is proposed. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1-4 , a DC ice melting device for transmission lines provided by the present utility model includes a line ice melting shell 1. Two side plates 10 are fixedly connected to the bottom surface of the line ice melting shell 1. A connecting bar 8 is fixedly connected to the bottom surface of each side plate 10. The front end sealing cover 2 is fixedly connected to the front surfaces of the two side plates 10 and the front surface of the line ice melting shell 1. The rear end sealing cover 14 is fixedly connected to the rear surfaces of the two side plates 10 and the rear surface of the line ice melting shell 1. Wire slots 4 are respectively opened on the front surfaces of the front end sealing cover 2 and the rear end sealing cover 14. Two first rubber sealing sheets 5 and two second rubber sealing sheets 15 are respectively fixedly connected to the inner walls of the two wire slots 4. The first heating sheet 11 is fixedly connected to the inner top wall of the line ice melting shell 1. The second heating sheets 13 are fixedly connected to the side surfaces of the two side plates 10 close to each other.

[0027] In this embodiment, two sealing silicone sheets 9 are provided between the two side plates 10. The side surfaces of the two sealing silicone sheets 9 away from each other are respectively fixedly connected to the side surfaces of the two connecting bars 8 close to each other. By providing the sealing silicone sheets 9, the lower part of the device can be sealed, reducing the entry of cold air into the device and reducing the loss of heat inside the device. Two drainage plates 16 are provided below the line ice melting shell 1. The bottom surfaces of the two drainage plates 16 are respectively fixedly connected to the upper surfaces of the two connecting bars 8. By providing the drainage plates 16, the dripping water can be guided so that the water can be quickly discharged from the device, preventing water from remaining inside the device.

[0028] In this embodiment, two groups of support rods 17 are fixedly connected to the inner wall of the line ice melting shell 1. The side surfaces of the two groups of support rods 17 close to each other are jointly fixedly connected with two limiting hoops 12. Through the cooperation of the support rods 17 and the limiting hoops 12, the cables of the transmission line can be limited, preventing the cables from directly contacting the first heating sheet 11 and causing damage to the cables. Two indicator lights 6 are fixedly connected to the side surfaces of the two side plates 10 away from each other. Two connecting pull rings 7 are fixedly connected to the side surfaces of the two side plates 10 away from each other. By providing the indicator lights 6, the device status can be displayed, facilitating the staff to understand the device status. A heat preservation board 3 is fixedly connected to the outer surface of the line ice melting shell 1. The inner wall of the heat preservation board 3 is in contact with the outer surfaces of the front end sealing cover 2 and the rear end sealing cover 14. By providing the heat preservation board 3, the line ice melting shell 1 can be heat-preserved, reducing the loss of heat.

[0029] Working principle: When in use, the device is sleeved outside the transmission line through the wire slot 4, then the power supply is connected, and the first heating sheet 11 and the second heating sheet 13 are started to heat the inside of the device, increasing the temperature inside the device, thereby melting the ice on the transmission line inside the device. And when moving, through the wire slot 4, the ice can smoothly enter the device, preventing the phenomenon that the device is difficult to move due to the blockage of ice cubes. At the same time, the second heating sheets 13 on both sides can quickly heat the ice cubes to melt them, and the melted water is discharged through the gap between the two sealing silicone sheets 9. During the operation of the device, the gaps of the device can be blocked by the sealing silicone sheets 9, the first rubber sealing sheet 5 and the second rubber sealing sheet 15, reducing the entry of cold air into the device, thereby reducing the loss of heat.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
