[0022] Embodiment 1

[0023] A cable protection tube comprises a tube body, an end connector, a supporting structure and a protective layer. The end connector is used to connect the tube body, the supporting structure is used to fix and protect the tube body, the protective layer is an additional protective structure of the cable protection tube, and is used to enhance the corrosion resistance and aging resistance of the tube body. The tube body is provided with a first groove and a second groove, and the first groove and the second groove are symmetrically arranged, and both of the first groove and the second groove are used for air circulation and heat dissipation inside the tube body.

[0024] The shapes of the first groove and the second groove can be set according to the needs of the actual application scenario of the cable protection tube, for example, they can be circular, square, elliptical or polygonal, etc. Here, the shapes of the first groove and the second groove are not limited.

[0025] The pipe body is the main part of the cable protection pipe, which is responsible for carrying and protecting the cable. In specific implementation, the pipe body can be a metal pipe or a plastic pipe. The metal pipe is a steel pipe or a galvanized pipe. The plastic pipe is a polyethylene pipe or a polyvinyl chloride pipe.

[0026] The cable will generate a certain amount of heat during operation. If the heat cannot be dissipated in time, the cable temperature may rise, affecting its normal operation. By symmetrically arranging the first groove and the second groove on the tube body, the heat dissipation of the tube body is facilitated to promote air circulation and heat dissipation in the tube. The symmetrical arrangement can also increase the firmness of the cable protection tube of the utility model. At the same time, the tube body itself also has a certain thermal conductivity, which can also help the cable to quickly dissipate heat and ensure its stable operation.

[0027] The main function of the cable protection tube is to protect the cable from the external environment. Through the wrapping and support of the tube body, the cable can be protected from mechanical damage, chemical corrosion, ultraviolet radiation and other factors. At the same time, the sealing of the tube body can also effectively prevent moisture, dust and other substances from entering the tube, keeping the cable dry and clean.

[0028] Since the cable line may be affected by environmental factors such as temperature and humidity during operation and may expand and contract, the cable protection tube needs to have a certain degree of flexibility and elasticity to adapt to this deformation. The material and structural design of the tube body should be able to withstand a certain degree of stretching, compression and bending to ensure the stability and safety of the cable line.

[0029] The end connector is used to connect the sections of the tube body to ensure the continuity and integrity of the cable protection tube, so that it forms a continuous protection channel. The design of the end connector must ensure the sealing and stability of the cable protection tube of the utility model, and prevent external factors such as moisture and dust from invading the tube and affecting the normal operation of the cable. In specific implementation, the end connector can be a flange, a socket or a threaded connection.

[0030] The support structure is an accessory of the cable protection tube of the utility model, and serves as a support and fixing device to help the cable protection tube remain stable in various environments. The support structure is used to fix and protect the tube body to prevent it from being deformed or displaced due to external forces. In specific implementation, the support structure can be in various forms, and the support structure can be a metal bracket or a plastic bracket, and its material and size can be selected according to the specific application scenario.

[0031] The protective layer is an additional protective structure of the cable protection tube, which is used to enhance the corrosion resistance and aging resistance of the tube body. In specific implementation, the protective layer is a coating or a covering layer, and different protective materials and processes can be selected according to different use environments.

[0032] In the field of power transmission, cable protection tubes play a vital role. They not only have to withstand various challenges brought by the external environment, such as soil corrosion, chemical erosion, mechanical damage, etc., but also ensure the safety and stability of the internal cables. Therefore, the selection of coating materials for cable protection tubes is directly related to the reliability and durability of the entire power transmission system.

[0033] In specific implementation, the coating can be any one of polyethylene (PE) coating, polypropylene (PP) coating and polyvinyl chloride (PVC) coating. Polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) and the like are all polymer materials, which have excellent corrosion resistance, weather resistance and mechanical strength, and can protect cables from damage in various harsh environments. Among them, polyethylene occupies an important position in the cable protection tube coating due to its excellent insulation performance and chemical stability.

[0034] The working principle of the coating mainly relies on its barrier effect and adhesion. On the one hand, the barrier formed by the coating material can effectively isolate the cable from direct contact with the external environment, preventing the cable from being corroded by moisture, oxygen, chemicals, etc. On the other hand, good adhesion is formed between the coating and the inner wall of the cable protection tube, ensuring that the coating is not easy to fall off or peel off, thereby maintaining a long-term protective effect.

[0035] In addition, the cable protection tube coating also needs to have excellent wear resistance and impact resistance. During the laying and use of cables, they may encounter operations such as excavation and burial. The coating must have sufficient toughness and strength to withstand these external forces without being damaged.

[0036] In specific implementation, the coating layer can be any one of a plastic coating layer, a metal coating layer or a rubber coating layer. Plastic coating layer plastic materials are widely used due to their good insulation, corrosion resistance and low cost. Metal coating layer metal materials, especially galvanized steel and stainless steel, are favored for their excellent mechanical strength and durability. Rubber coating layer rubber materials are selected in many occasions due to their excellent elasticity and weather resistance.

[0037] The plastic coating is mainly wrapped around the outer layer of the cable to form a protective layer to protect the cable from external damage, such as moisture, chemicals and mechanical damage. At the same time, the plastic coating can also provide good insulation properties to ensure that the signal or power transmitted by the cable is not interfered with.

[0038] Metal coating: Metal has good conductivity and mechanical strength, so the metal coating can not only prevent the cable from mechanical damage, but also enhance the electromagnetic shielding capability of the cable to a certain extent and reduce the impact of electromagnetic interference on the cable signal.

[0039] The rubber coating mainly uses its elasticity and weather resistance to protect the cable. Rubber can maintain good elasticity in an environment with large temperature changes, thereby effectively buffering the impact and vibration of the cable from the outside world and extending the service life of the cable.

[0040] In specific implementation, the tube body can be set to round, square, oval or polygonal according to actual needs to adapt to different cable line layout requirements. In addition, the inner wall of the tube body is set to be smooth to reduce friction between the cable and the tube body, while facilitating the insertion and replacement of the cable.

[0041] The beneficial effects of implementing the cable protection tube of the utility model are as follows: by arranging a tube body, an end connector, a supporting structure and a protective layer, the end connector is used to connect the tube body, the supporting structure is used to fix and protect the tube body, the protective layer is an additional protective structure of the cable protection tube, and is used to enhance the corrosion resistance and aging resistance of the tube body, the tube body is provided with a first groove and a second groove, the first groove and the second groove are symmetrically arranged, and the first groove and the second groove are both used for air circulation and heat dissipation inside the tube body; it can provide a safe and stable operating environment for the cable; by wrapping the outside of the cable, the cable protection tube can resist external physical impact and chemical erosion, and reduce the risk of cable damage; at the same time, the cable protection tube can also maintain appropriate spacing between the cables, prevent mutual interference between the cables, and ensure the stability and efficiency of power transmission.
