Description

Technical Field

[0001] The utility model relates to a heating device for a cable, which is applicable to the technical field of cable laying. Background Art

[0002] In electrical construction, cable laying mainly covers primary equipment and relay protection low-voltage equipment lines. In photovoltaic projects, wind power projects, water conservancy and hydropower, thermal power, and building electrical engineering, cable laying is of great importance and requires high safety and aesthetics. The cable laying methods often use buried cable laying; overhead cable laying; and pipe-type cable laying. In this regard, in cable laying, it is necessary to ensure that the cable can operate reliably during power-on operation. However, in some areas with low temperatures, laying cables will cause certain frostbite to the cables, affecting their safety. When laying cables, the following solutions are often adopted: move the entire cable to a house with sufficient space for preheating, and ensure that the indoor temperature is around 25°C. Wait until the cable temperature reaches and exceeds the specified temperature before rapid laying and construction. The laying time should not be too long and should be controlled within 4 hours. The ideal time period should be from 10 am to 14 pm. However, the cost of this method is too high and requires a large space. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to solve the above technical problem, the utility model provides a heating device for a cable.

[0004] The technical solution adopted by the utility model is: a heating device for a cable, characterized in that it has:

[0005] A through pipe, through which the cables can pass;

[0006] A heating module is arranged on the through pipe and is used to heat the cable extending into the through pipe;

[0007] The control terminal is installed on the through-tube and connected to the heating module circuit to adjust the heating power and operation time of the heating module. In this way, after the cable is inserted into the through-tube, the control terminal controls the operation of the heating module and heats the cable in the through-tube, which can efficiently heat the cable while occupying a small space.

[0008] The heating module comprises a heater installed on the inner wall of the through pipe along the through-length direction of the through pipe, and the heater is connected to a power supply circuit.

[0009] Support columns are installed at both sides of the cable in the through pipe, and rollers that can roll with the cable are installed on the support columns. In this way, when the cable is inserted into the through pipe, the cable and the through pipe can be effectively prevented from being worn out under the cooperation of the rollers and the cable.

[0010] The cross section of the through pipe is a regular octagon, so that the through pipe can be placed on the ground easily, and when one side of the through pipe contacts the ground, the through pipe can be effectively prevented from moving on the ground when the heater heats the cable in the through pipe; and the through pipe can also be rolled on the ground easily.

[0011] The beneficial effects of the utility model are as follows: the utility model arranges a heating module in the through pipe, so that when the cable is inserted into the through pipe, the heating module in the through pipe heats the cable; because the space in the through pipe is compact, the heating efficiency of the cable is higher and more energy-saving; the utility model arranges a control terminal on the through pipe that can adjust the heating power and operating time of the heating module, so that it is convenient to regulate the heating of the cable; the utility model installs a support column on the inner wall of the through pipe and installs a roller on the support column that rolls with the cable, so that when the cable is inserted into the through pipe, wear between the cable and the through pipe can be effectively avoided.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0015] This embodiment is a heating device for a cable 7, which has a through-tube 1, through which the cable 7 can pass.

[0016] In this embodiment, the cross section of the through pipe 1 is a regular octagon. Thus, the octagonal through pipe 1 has good structural strength, and is convenient for placing the through pipe 1 on the ground. When one side of the through pipe 1 contacts the ground, the through pipe 1 can be effectively prevented from moving on the ground when the heater 2 heats the cable 7 in the through pipe 1; and the through pipe 1 can also be easily moved on the ground by rolling.

[0017] In this embodiment, support columns 3 are installed at both sides of the cable 7 in the through pipe 1, and rollers 4 that can roll with the cable 7 are installed on the support columns 3. In this way, when the cable 7 is inserted into the through pipe 1, the cable 7 and the through pipe 1 can be effectively prevented from being worn due to the rolling cooperation between the cable 7 and the rollers.

[0018] In this embodiment, a heating module is provided on the inner wall of the through pipe 1, wherein a heater 2 is installed on the inner wall of the through pipe 1 along the length of the through pipe 1, and the heater 2 is connected to a power circuit, wherein the power source is a blade lithium battery installed in the inner wall of the through pipe 1. In this way, when the cable 7 is arranged in the through pipe 1, the power of the heater 2 is turned on, and the heater 2 can heat the cable 7.

[0019] In this embodiment, a charger 6 is installed on the outer wall of the through pipe 1, and the charger 6 is connected to the blade lithium battery. The blade lithium battery can be powered by connecting the charger 6 to an external power source.

[0020] In this embodiment, a control terminal 5 connected to the heating module circuit is installed on the outer wall of the through pipe 1, so that personnel can adjust the heating power and operation time of the heating module by operating the control terminal 5.

[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
