They mainly consist of one or more insulated wire cores, as well as their respective covering layers, overall protective layers and outer sheaths. They are one of the main means of transmitting electrical energy and information.

[0003] When connecting existing power cable protection pipes, the common method is to wrap the connection ends of the two cables together and then wrap them with insulating cloth for protection. However, this method is very easy to be damaged by the high temperature at the connection point, which can lead to circuit breakage or short circuit. It is not safe enough and the connection is not tight. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure for a power cable protection pipe. The connecting ends of the front cable body and the rear cable body are wound together and then a heat fusion tube is sleeved on. The front connecting pipe and the rear connecting pipe are then sleeved on the outside of the heat fusion tube, so that the front connecting pipe and the rear connecting pipe are threaded together and the heat fusion tube is stabilized. The surface of the front connecting pipe and the rear connecting pipe is heated to melt the internal heat fusion tube. After cooling, the front cable body, the rear cable body, the front connecting pipe and the rear connecting pipe are tightly connected together. This not only makes the connection more secure and safer, but also has a simple structure and is easy to operate.

[0005] To achieve the above objectives, a power cable protection pipe connection structure is provided, comprising: a front cable body and a rear cable body, a front connecting pipe sleeved on the front cable body, a front sealing ring fixedly connected to the front side wall of the front connecting pipe, and a front hole provided on the front sealing ring; a rear connecting pipe sleeved on the rear cable body, a rear sealing ring fixedly connected to the rear side wall of the rear connecting pipe, and a rear hole provided on the rear sealing ring; a heat fusion pipe sleeved inside the front connecting pipe, a heat insulation plate fixedly connected to the inner circumferential surface of the heat fusion pipe, and a waterproof layer fixedly connected to the inner circumferential surface of the heat insulation plate.

[0006] According to the aforementioned power cable protection pipe connection structure, the inner circumferential surfaces of the front connecting pipe and the rear connecting pipe are threaded together.

[0007] According to the aforementioned power cable protection pipe connection structure, the front connecting pipe, front sealing ring, rear connecting pipe, and rear sealing ring are all made of stainless steel. Stainless steel is not only lightweight but also heat-resistant and rust-resistant.

[0008] According to the aforementioned connection structure for a power cable protection pipe, the waterproof layer is a polyurethane waterproof coating. The cured polyurethane waterproof coating forms a film with excellent overall performance, capable of forming a continuous, elastic, seamless, and integral waterproof layer on complex-shaped substrates. It exhibits strong adhesion to various substrates, strong adaptability to substrate expansion, deformation, and cracking, and good high-temperature resistance. It not only provides waterproofing but also connects the front and rear cable bodies.

[0009] According to the aforementioned connection structure for a power cable protection pipe, the insulation board is made of ceramic fiber. It possesses advantages such as light weight, high temperature resistance, low heat capacity, good thermal insulation performance, good high-temperature insulation performance, and non-toxicity, making it an excellent refractory material.

[0010] According to the aforementioned power cable protection pipe connection structure, the heat fusion pipe is located between the front sealing ring and the rear sealing ring. When the front connecting pipe and the rear connecting pipe are connected together, the heat fusion pipe can be tightly clamped inside.

[0011] According to the aforementioned power cable protection pipe connection structure, both the front cable body and the rear cable body mainly include a protection pipe and an inner core.

[0012] The above solution has the following advantages: By setting up a front cable body, a rear cable body, a front connecting pipe, a front sealing ring, a front hole, a rear connecting pipe, a rear sealing ring, a rear hole, a heat fusion pipe, a heat insulation board, and a waterproof layer, the connecting ends of the front cable body and the rear cable body are wound together. Then, a heat fusion pipe is fitted on top, and the front and rear connecting pipes are fitted on the outside of the heat fusion pipe, so that the front and rear connecting pipes are threaded together and the heat fusion pipe is stabilized. The surfaces of the front and rear connecting pipes are heated to melt the internal heat fusion pipes. After cooling, the front cable body, the rear cable body, the front connecting pipe, and the rear connecting pipe are tightly connected together. This not only makes the connection more secure and safer, but also has a simple structure and is easy to operate.

A heat-melting pipe 9 is sleeved inside the front connecting pipe 3. A heat insulation board 10 is fixedly connected to the inner circumference of the heat insulation board 10. The heat insulation board 10 is made of ceramic fiber material, which has the advantages of light weight, high temperature resistance, low heat capacity, good thermal insulation performance, good high temperature insulation performance, and non-toxicity. It is an excellent refractory material. A waterproof layer 11 is fixedly connected to the inner circumference of the heat insulation board 10. The waterproof layer 11 is a polyurethane waterproof coating. The coating film formed by the curing of polyurethane waterproof coating has excellent comprehensive performance. It can form a continuous, elastic, seamless, and integral waterproof film on the complex-shaped base layer.
