Description

Technical Field

[0001] The present invention relates to a cable, in particular to an automatic snow removal cable for alpine mountainous areas, belonging to the technical field of cables. Background Art

[0002] A cable is a device for transmitting electric energy or signals. It is usually composed of several or several groups of wires, made of one or more mutually insulated conductors and an outer insulating protective layer, and is a wire for transmitting electric power or information from one place to another. It is usually a cable in the form of a rope twisted by several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The whole is covered with a highly insulating covering layer. The cable has the characteristics of being energized inside and insulated outside. There are power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mine cables, aluminum alloy cables, etc. They are all composed of single-stranded or multi-stranded wires and insulating layers, and are used to connect circuits, electrical appliances, etc. They are widely used in modern society. In order to facilitate power supply or communication in alpine mountainous areas, it is necessary to lay cables in alpine mountainous areas. Due to the high altitude and low temperature in alpine mountainous areas, especially in winter, there will be a large amount of snowfall. When it snows, due to the low temperature, the snow often adheres to the cable, causing snow accumulation on the cable. When the snow accumulation is excessive, it will cause the weight borne by the cable to increase, easily resulting in fracture. Therefore, it is necessary to remove the snow on the cable. However, when removing snow in alpine mountainous areas, it is extremely difficult for personnel to enter, resulting in difficult snow removal and inconvenient snow removal. There are also some cables with snow removal functions at present. For example, the publication number is: CN204157085U, a snow melting and heating cable. By using two heating conductors, the first conductor and the second conductor, the two heating conductors are alternately energized and heated, increasing the service life. The multi-layer structure design can well prevent ultraviolet rays and is suitable for snow melting and ice melting. And a tensile strengthening rib is provided to make the cable itself more tough and tensile. A detachable transition conductor is provided outside the two heating conductors, so that the two heating conductors can be energized at the same time, generating heat more quickly; The structure of the present invention is simple, has good heating performance, and has a long service life, and is suitable for snow melting.

[0003] Publication number: CN207124778U, a snow melting and ice thawing temperature controlled heating cable, including an elastic expansion outer sheath. Inside the elastic expansion outer sheath, there are high-voltage transmission lines, a first heating cable, a second heating cable, a first heating power supply cold wire, and a second heating power supply cold wire. One end of the first heating cable and the second heating cable are electrically connected to each other. The other ends of the first heating cable and the second heating cable are respectively connected to the first heating power supply cold wire and the second heating power supply cold wire. A heating temperature control device is arranged between the first heating cable and the first heating power supply cold wire. The elastic expansion outer sheath is filled with an inert insulating protective gas. A snow melting and ice thawing temperature controlled heating cable provided by the present invention can quickly remove the ice and snow on the high-voltage transmission line, so as to reduce the operation energy consumption and shorten the heating time.

[0004] However, in use, heating wires are all adopted to make the cable generate heat to achieve the purpose of snow melting and snow removal. But when used in alpine mountainous areas, due to the long cable laying, when snow accumulates at one end and needs to be removed, while there is no snow accumulation in other sections and no snow removal is required, it is not convenient to flexibly adjust the area that needs snow removal. When in use, the whole cable needs to be heated to remove snow, which causes inconvenience in control and is not convenient for sectional snow removal and use. Moreover, when multiple current cables are connected, most of them are fixed by external connectors. When fixing, only relying on the friction force between the connector and the cable to achieve the fixing effect, it is not convenient to use. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic snow removal cable for alpine mountainous areas to facilitate snow removal, convenient for sectional control, and convenient for connecting cables and assembling.

[0006] The present invention achieves the above object through the following technical solutions. An automatic snow-removing cable for alpine regions includes a cable and a connector, and the cables are assembled through the connector so that the cables form a row. The cable includes an inner skeleton, and main conductors are evenly inserted on both sides inside the inner skeleton. The inner skeleton is a sheet-like structure, and mica powder is filled between the inner skeletons. A secondary conductor is inserted at the upper end of the inner skeleton. The main conductors and the secondary conductor are both wrapped between the mica powder, and the main conductors and between the main conductor and the secondary conductor are isolated by the mica powder. First insertion holes are evenly formed on both sides of the inner skeleton, and the main conductors are inserted inside the first insertion holes. A second insertion hole is formed at the upper end of the inner skeleton, and the secondary conductor is inserted inside the second insertion hole. A micro-vibrator with voltage transformation and control functions is fixedly installed at the lower end of the inner skeleton. The outer side of the inner skeleton and the mica powder is wrapped with a heat insulation layer, and a heating wire is spirally wound on the outer side of the heat insulation layer. The heating wire and the micro-vibrator are both electrically connected to the secondary conductor. A heat-conducting silicon sheet is filled between the heating wires. The outer side of the heat-conducting silicon sheet is wrapped with an insulating layer, and the outer side of the insulating layer is wrapped with an outer protective layer. A through hole is formed at the middle position of the inner skeleton, and a reinforcing rib is inserted inside the through hole. When in use, when multiple cables are needed, the cables are connected through the connector, and after connection, the cables form a row, which is convenient for connection and fixing. When in use, between the cables, through the inner skeleton, mica powder is filled between the inner skeletons. By using the characteristics of the mica powder such as insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, and strong adhesion, the main conductors and the secondary conductor are isolated, achieving a good isolation effect and avoiding interference. The main conductor is responsible for power transmission, and the secondary conductor is responsible for supplying power to the heating wire and the micro-vibrator. The outer side of the mica powder is coated with a heat insulation layer. When the heating wire works, the efficiency of the heat emitted by the heating wire conducting towards the main conductor is reduced, thereby avoiding the main conductor from being exposed to a high temperature. A heat-conducting silicon sheet is filled between the heating wires, thereby improving the uniformity of heat conduction when the heating wire generates heat, enabling the heat to be evenly conducted to the outside of the present invention. Through the insulating layer, the present invention is insulated and isolated from the outside. Through the outer protective layer, a strong protection effect is provided for the cable, improving the service life. When used in alpine regions, when snow accumulates above the cable, by supplying power to the secondary conductor, the heating wire and the micro-vibrator are turned on. The heating wire heats the heat-conducting silicon sheet, enabling the heat to be evenly conducted to the insulating layer and the outer protective layer, increasing the surface temperature of the outer protective layer.Furthermore, the snow accumulated on the surface of the outer protective layer is heated and melted. When the micro vibrator is turned on, the cable vibrates. The micro vibrator is fixedly installed on the inner skeleton. There are multiple inner skeletons, and the inner skeletons are evenly installed inside the cable. As a result, the micro vibrators are distributed in stages inside the cable, causing the micro vibrators to drive the cable to vibrate in stages, shaking off the snow accumulated on the cable. Moreover, the position where the outer protective layer contacts the snow melts, improving the lubricity between the snow and the cable, facilitating the shaking off of the snow from the cable, achieving the snow removal effect and being convenient for use.

[0007] Preferably, in order to facilitate the connection between the cables, threaded cylinders are evenly embedded and installed on the outer side of the outer protective layer. A connecting wire is fixedly installed between the threaded cylinder and the inner skeleton. The connecting wire sequentially passes through the heat insulation layer, the heat conducting silicon sheet and the insulating layer and is fixedly connected to the threaded cylinder on the outer protective layer. The connecting piece is fixedly connected to the threaded cylinder. The connecting piece is composed of a clamp. The two sides of the clamp are of a C-shaped structure. Through holes are evenly formed in the clamp. A one-way bolt is threadedly connected inside the through hole. One end of the one-way bolt is threadedly connected inside the threaded cylinder. Connecting holes are formed at both ends of the clamp. A double-headed bolt is sleeved inside the connecting hole. The clamps are fixedly connected through the double-headed bolt. The connecting piece is fixedly connected to the cable through the clamp. The inner side of the clamp presses against the outer surface of the outer protective layer. When connecting the cables, the clamp is used to fix the cable, and through the one-way bolt, the clamp is fixedly connected to the threaded cylinder. Thus, after fixation, sliding is avoided, and the stability after combination is improved.

[0008] Preferably, in order to facilitate segmented power supply to the secondary conductor and achieve the effect of segmented snow removal, the middle positions of the secondary conductors penetrate through the outer protective layer and extend to the outside of the outer protective layer. The middle positions of the secondary conductors extending to the outside of the outer protective layer are in a separated state. A connecting sub-head is fixedly installed on one end of the secondary conductor, and a connecting female head is fixedly installed on the other end of the secondary conductor. The secondary conductors are electrically connected through the connecting sub-head and the connecting female head. Both the connecting sub-head and the connecting female head are waterproof structures. The secondary conductor includes a neutral wire, a live wire, and a ground wire. The outer surfaces of the neutral wire, the live wire, and the ground wire are all insulated. The neutral wire, the live wire, and the ground wire form a twisted chain structure. Insulating fillers are filled in the interlaced gaps between the neutral wire, the live wire, and the ground wire. A rubber layer is wrapped outside the insulating fillers. The secondary conductor is inserted into the inner skeleton through the rubber layer. The neutral wire, the live wire, and the ground wire are all electrically connected to the heating wire and the micro-vibrator. When performing segmented power supply, through the connecting female head and the connecting sub-head, it is convenient to disconnect or connect the secondary conductors to an external power supply line, enabling the heating wire and the micro-vibrator to work, achieving the snow removal effect, facilitating power supply to the area where snow removal is required, and not supplying power to the area where snow removal is not required, facilitating flexible control.

[0009] Preferably, in order to facilitate the installation of the micro-vibrator and enhance the anti-tensile ability, a notch is opened at the lower end of the inner skeleton. A connecting rod is fixedly installed at the lower end inside the notch. A vibrating box is fixedly installed at the lower end of the connecting rod. The micro-vibrator is fixedly installed inside the vibrating box. The vibrating box is a hollow cylindrical structure. The vibrating box is located inside the notch. A reinforcing rib is inserted in the middle position of the inner skeleton. The reinforcing rib is composed of a metal wire and a nylon fiber wire. The nylon fiber wire is intertwined outside the metal wire. Through the vibrating box, it is convenient to install the micro-vibrator. And through the reinforcing rib, the anti-tensile ability of the present invention is increased, thereby avoiding being broken under the pressure of accumulated snow and improving the bearing capacity.

[0010] Preferably, for the purpose of facilitating protection, the main conductor includes an inner conductor. The inner conductor is in a bundle structure. Flame-retardant fillers are filled between the inner conductors. A shielding layer is wrapped outside the inner conductor. An inner protective layer is coated outside the shielding layer. The main conductor is inserted into the inner skeleton through the inner protective layer. The inner protective layer and the outer protective layer are composed of an anti-tensile layer, a braided layer, and a wear-resistant layer. The anti-tensile layer is attached to the inner side of the braided layer. The wear-resistant layer is coated outside the braided layer. Through the braided layer and the anti-tensile layer, the anti-tensile effect is further improved, and the bearing capacity is increased. And through the wear-resistant layer, damage is avoided during wear.

[0011] The beneficial effects of the present invention are as follows: By adopting a main conductor and a secondary conductor, and uniformly and segmentally installing connecting male heads and connecting female heads on the secondary conductor, it is convenient to supply power to the secondary conductor in segments, enabling the heating wires and micro-vibrators in the cable to be turned on in segments, thereby facilitating automatic snow removal from the snow-covered sections, avoiding the heating wires and micro-vibrators in the non-snow-covered sections from being turned on, melting the snow through the heating wires, and shaking off the snow through the micro-vibrators. Moreover, through the inner skeleton and the threaded cylinder, when assembling, the one-way screws on the connecting piece are threadedly connected to the threaded cylinder, which is convenient for assembly and prevents sliding after assembly.
