[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-Figure 4The water-cooled cable jacket hose shown in the figure includes a cable body 1. The cable body 1 is used to transmit electricity and is the main carrier in power transmission. An insulating mechanism is arranged outside the cable body 1. The insulating mechanism includes a resin hose 4. The resin hose 4 has chemical corrosion resistance, high temperature resistance, wear resistance and good insulation performance, which can improve the insulation of the cable and increase the service life of the cable.

[0023] The resin hose 4 is fixedly provided with a waterproof layer 3, which is made of rubber material, but is not limited to rubber material. Anti-corrosion paint is applied between the waterproof layer 3 and the resin hose 4 to further reduce the problem of aging of the rubber material.

[0024] An insulating layer 2 is fixedly installed inside the waterproof layer 3. The insulating layer 2 is made of polyethylene, but is not limited to polyethylene. Polyethylene has good electrical properties, physical properties, high thermal stability and chemical corrosion resistance. It is a common insulating material. The insulating layer 2 is fixedly mounted on the cable body 1.

[0025] One end of the cable body 1 is provided with a water cooling joint 11, which is used to connect the components between the water cooling cable and the induction coil. The main function is to achieve high current transmission between the cable and the induction coil and ensure that the water cooling liquid can circulate inside the cable, thereby effectively reducing the temperature of the cable.

[0026] It should be noted that the induction coil is a common electrical component in the prior art and will not be described in detail here.

[0027] Furthermore, a supporting mechanism is provided at the inner circle of the cable body 1, and the support includes an outer supporting tube 6, which is used to support the cable body 1 to prevent the cable from being deformed due to bending. The outer supporting tube 6 is fixedly inserted into the cable body 1, and an inner supporting tube 7 is provided inside the outer supporting tube 6. The inner supporting tube 7 is used to circulate cooling liquid to reduce the temperature of the cable by the flow of liquid. A snap-fitting block 10 is integrally formed at the outer circle of the inner supporting tube 7, and a snap-fitting groove 9 is integrally formed on the inner circle of the outer supporting tube 6. The snap-fitting groove 9 cooperates with the snap-fitting block 10 to fix the inner supporting tube 7 on the outer supporting tube 6.

[0028] Specifically, the snap-fitting groove 9 is triangular in shape, and the triangular structure can well fix the inner support tube 7 on the outer support tube 6 to avoid displacement when the cable is bent. There are two snap-fitting grooves 9, and the two snap-fitting grooves 9 are mirror-distributed. There are two snap-fitting blocks 10, and the two snap-fitting blocks 10 correspond to the two snap-fitting grooves 9 one by one. The snap-fitting blocks 10 are slidably connected in the corresponding snap-fitting grooves 9.

[0029] It should be noted that the outer support tube 6 and the inner support tube 7 are made of rubber material, which has good flexibility and certain anti-slip properties and is very suitable for occasions where the cable is bent, but is not limited to rubber material.

[0030] The water-cooling joint 11 is fixedly mounted on the inner support tube 7 . A side of the water-cooling joint 11 close to the resin hose 4 is fixedly connected with a water inlet pipe, which is used to connect the resin hose 4 .

[0031] During operation, the locking block 10 is locked in the locking groove 9, and the water-cooling liquid is input from the water-cooling joint 11, so that the water-cooling liquid circulates in the inner support tube 7 to dissipate heat from the cable body 1, thereby achieving the goal that after long-term use, the inner support tube 7 will be aged due to the erosion of the water-cooling liquid. By replacing the inner support tube 7, the overall service life of the water-cooled cable is increased.

[0032] Taking into account that after the water-cooled cable is covered with the outer jacket hose, although the insulation performance is enhanced, its flexibility is reduced and it is not easy to bend, and the heat dissipation capacity becomes poor. Therefore, a heat dissipation groove 8 is integrally formed on the outer ring of the outer support tube 6. The heat dissipation groove 8 is used to transfer the heat generated by the cable body 1 during operation. The heat dissipation groove 8 is spiral. The spiral structure can increase the friction coefficient on the surface of the outer support tube 6, thereby increasing the friction force during torsion, improving the torsion capacity of the outer support tube 6, and improving the heat dissipation effect of the cable.

[0033] Furthermore, a heat dissipation pipe 5 is opened at one end of the resin hose 4, and the heat dissipation pipe 5 is used to enhance the heat dissipation effect of the water-cooled cable. The heat dissipation pipe 5 has an arc-shaped structure, and the arc-shaped structure can increase the flow rate of the coolant, so that the wound cable can be quickly straightened after the coolant is input, which reduces labor time and improves work efficiency. There are multiple heat dissipation pipes 5, and setting multiple heat dissipation pipes 5 can further improve work efficiency and increase heat dissipation effect, and multiple heat dissipation pipes 5 are distributed circumferentially on the resin hose 4, and the heat dissipation pipe 5 is connected to the water inlet pipe.

[0034] During specific operation, the coolant is input from the water cooling joint 11, and the coolant enters the outer circle and the inner circle of the cable body 1 through the water inlet pipe and the inner support pipe 7 respectively, so as to realize heat dissipation of the cable.
