[0033] like Figs. 1-3 As shown, an electrical engineering automation cable protection device includes an upper housing 1 and a lower housing 2. The upper housing 1 and the lower housing 2 are arranged opposite to each other and connected by bolts 3. The circular tube structure formed by the upper housing 1 and the lower housing 2 has multiple movable windows 8. A mounting shell 4 is slidably inserted into the movable window 8. One end of the mounting shell 4 is connected to a clamping plate 5. A heat dissipation assembly 7 is arranged inside the mounting shell 4. The heat dissipation assembly 7 includes a heat pipe 701 and a heat dissipation fin 702. The heat dissipation fin 702 is installed on the mounting shell 4. The heat pipe 701 has a U-shaped structure. The evaporation section of the heat pipe 701 is attached to the surface of the clamping plate 5, and the condensation section of the heat pipe 701 is inserted into the heat dissipation fin 702.

[0034] The clamping plate 5 is an arc-shaped aluminum plate structure. The direction of movement of the mounting shell 4 within the movable window 8 is the radial direction of the circular tube structure composed of the upper shell 1 and the lower shell 2. The clamping plate 5 is made of aluminum alloy, which can better conduct heat.

[0035] One end of the spring 6 is connected to the inner wall of the upper housing 1 and the lower housing 2, and the other end of the spring 6 is connected to the clamping plate 5; the spring 6 allows the clamping plate 5 to better fit the electrical tape wrapping connection point.

[0036] There are multiple springs 6, and the multiple springs 6 are equidistantly spaced along the axial direction of the circular tube structure formed by the upper shell 1 and the lower shell 2; the multiple springs 6 can apply stable pressure to the clamping plate 5, so that the pressure on the cable at all points of the clamping plate 5 is similar, thereby ensuring the tightness of the clamping plate 5 and the cable.

[0037] There are multiple bolts 3, and the multiple bolts 3 are equidistantly spaced along the axial direction of the circular tube structure composed of the upper shell 1 and the lower shell 2; the multiple bolts 3 can stably connect the upper shell 1 and the lower shell 2, ensuring that the upper shell 1 and the lower shell 2 provide stable support for the clamping plate 5.

[0038] A protective frame 41 is installed on the mounting shell 4, which covers the outside of the heat sink 702. The protective frame 41 can effectively protect the heat sink 702 and heat pipe 701, and prevent damage and deformation of the heat sink 702 and heat pipe 701 caused by external impacts and pressure.

[0039] Multiple heat dissipation fins 702 are equidistantly arranged on the condensation section of heat pipe 701, and the insulation section of heat pipe 701 is inserted through the upper shell 1 and the lower shell 2; the heat on the clamping plate 5 is quickly transferred to the heat dissipation fins 702 through the heat pipe 701, and then dissipated into the air through the heat dissipation fins 702, thus achieving a highly efficient heat dissipation function.

[0041] In the process of using the cable, the clamping plate 5 closely fitted on the surface of the cable transmits the heat on the surface of the cable to the evaporation section of the heat pipe 701, the medium in the evaporation section vaporizes after absorbing heat and enters the condensation section of the heat pipe 701, the heat dissipation fin 702 can increase the heat dissipation area of the condensation section, improve the heat dissipation efficiency of the heat pipe 701 in the air, make the medium quickly release heat and liquefy, and return to the evaporation section under the action of the capillary, so as to work reciprocatingly, compared with the simple use of the heat dissipation fin, the heat dissipation efficiency is higher.
