[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figures 1-4An electrical engineering automation cable protection device includes a protection device 1. The protection device 1 includes an upper protective semi-circular strip 11 and a hinge 16 installed on one side of the upper protective semi-circular strip 11. A lower protective semi-circular strip 12 is installed on one side of the hinge 16. Sealing bends 14 and rubber bends 15 are installed on both sides of the interior of the upper protective semi-circular strip 11 and the lower protective semi-circular strip 12. A connecting member 17 is installed on the side of the upper protective semi-circular strip 11 and the lower protective semi-circular strip 12 that is in contact with each other. The sealing bends 14 and rubber bends 15 installed inside the upper protective semi-circular strip 11 and the lower protective semi-circular strip 12 wrap the cables at both ends of the device to prevent insufficient contact between the device and the cables, which could lead to rainwater or other impurities coming into contact with the cables.

[0024] The upper protective semi-arc strip 11 includes an arc strip A111 and a heat dissipation component 13 installed on the inner wall of the arc strip A111. An inner connecting bend strip A114 is installed on the inner side of the heat dissipation component 13. A heat dissipation hole 112 is opened through the outer surface of the arc strip A111. The inner connecting bend strip A114 contacts the outer surface of the cable. The inner connecting bend strip A114 and the heat dissipation component 13 absorb heat and dissipate heat through the heat dissipation hole 112.

[0025] The heat dissipation component 13 includes an inner protective bend frame 131 and heat dissipation fins 132 installed inside the inner protective bend frame 131. A reflective heat insulation film 113 is installed inside the heat dissipation holes 112. The reflective heat insulation film 113 blocks the inside of the heat dissipation holes 112, ensuring heat dissipation. The principle of the reflective heat insulation film 113 is mainly based on the reflection and absorption of thermal radiation to achieve the heat insulation effect. Through a special coating and material structure, it reflects the heat of solar radiation back into the atmosphere, thereby reducing the heat entering the device.

[0026] The lower protective semi-circular strip 12 includes an arc strip B121 and an inner connecting bend strip B122 installed inside the arc strip B121. A Z-shaped inner plate 124 and an inner attached bend strip 125 are installed between the arc strip B121 and the inner connecting bend strip B122. The inner attached bend strip 125 is connected to the outside of the inner connecting bend strip B122. The top end of the Z-shaped inner plate 124 is connected to the inner attached bend strip 125, and the bottom end of the Z-shaped inner plate 124 is connected to the inner wall of the arc strip B121. Moisture-absorbing particles 123 are provided inside the space formed by the arc strip B121, the inner attached bend strip 125 and the Z-shaped inner plate 124. The moisture-absorbing particles 123 are used to dehumidify the air.

[0027] The connecting component 17 includes a side strip A171 installed on one side of the arc strip A111. The lower end of the side strip A171 is provided with a side strip B174. The middle end of the side strip A171 is provided with a threaded hole A172, and the middle end of the side strip B174 is provided with a threaded hole B175. The positions of the threaded hole A172 and the threaded hole B175 are aligned. A bolt is inserted into the interior of the threaded hole A172 and the threaded hole B175 to connect the side strip A171 and the threaded hole A172, thereby achieving the connection between the upper protective semi-arc strip 11 and the lower protective semi-arc strip 12.

[0028] In this embodiment: the upper protective semi-circular strip 11 and the lower protective semi-circular strip 12 are connected on their adjacent sides by a hinge 16. The lower protective semi-circular strip 12 is located below the cable. Rotating the upper protective semi-circular strip 11 causes the unconnected sides of the upper protective semi-circular strip 11 and the lower protective semi-circular strip 12 to come into contact. The side connecting strip A171 covers the top of the side connecting strip B174. The threaded hole B175 is aligned with the threaded hole A172. The rubber strip 173 is inserted into the U-shaped groove 176 and connected to the threaded holes B175 and A172 by a bolt thread to fix the upper protective semi-circular strip 11 and the lower protective semi-circular strip 12. The compression of strip 173 prevents external impurities from entering the device through the gap between the side strip A171 and the threaded hole A172. During cable operation, the heat generated is absorbed by the inner bend strip A114. The heat from the inner bend frame 131 and the heat dissipation fins 132 are absorbed by the inner bend strip A114, and the heat is discharged through the heat dissipation hole 112. In rainy weather, the reflective heat insulation film 113 inside the heat dissipation hole 112 can block rainwater and other substances, preventing external substances from directly contacting the cable. The reflective heat insulation film 113 reflects the heat from solar radiation, reducing the amount of heat entering the device and reducing external damage to the cable.

[0029] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The top of the arc strip B121 and the threaded hole A172 are provided with a U-shaped groove 176. The top of the arc strip A111 and the side connecting strip A171 are provided with a rubber strip 173. The rubber strip 173 matches the U-shaped groove 176 and is used to seal the connection member 17, the upper protective semi-arc strip 11 and the lower protective semi-arc strip 12.

[0030] An opening A126 is provided through the middle of the Z-shaped inner plate 124. A dense mesh 127 is installed inside the opening A126. An opening B128 is provided through the middle of the inner curved strip 125. A waterproof and breathable membrane 129 is installed inside the opening B128. The dense mesh 127 and the waterproof and breathable membrane 129 can restrain the moisture-absorbing particles 123. At the same time, the openings A126 and B128 are located at the junction of the inner curved strip A114 and the inner curved strip B122, and at the junction of the arc strip B121 and the arc strip A111.

[0031] In this embodiment: During the use of the device, when outside air enters the device through the gap between arc strip A111 and arc strip B121, the air first enters the space formed by arc strip A111, arc strip B121, inner protective curved frame 131 and Z-shaped inner plate 124. The air is discharged into the space formed by arc strip B121, Z-shaped inner plate 124 and inner attached curved strip 125 through opening A126. The moisture in the air is absorbed by the moisture-absorbing particles 123. After dehumidification, the air comes into contact with the cable through the gap between inner connected curved strip A114 and inner connected curved strip B122 through opening B128. The waterproof and breathable membrane 129 set inside opening B128 blocks substances in the air but does not affect the airflow.
