[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention provides a multi-protection power cable protection cover, such as Figure 1 - Figure 6 As shown, the multi-protection power cable protective cover comprises a protective tube 1, the surface of the protective tube 1 is fixedly connected with reflective strips 22 in a circular array. The reflective strips 22 are arranged to make the protective tube 1 more conspicuous under the illumination of a lamp at night, so as to prevent pedestrians from hitting the protective tube 1 without being able to find it in time, thereby affecting the protective tube 1 and the power cable; A wind collecting mechanism is installed on the surface of the protection tube 1. The wind collecting mechanism includes an energy storage box 15 fixedly connected to the surface of the protection tube 1 and electrically connected to the electric air pump 2 through a wire. A fixing plate 16 is fixedly connected to one side of the energy storage box 15. The protection tube 1, the extension tube 5 and the protection cover 20 are installed on the surface of the power cable. The fan assembly 17 is driven to rotate by natural wind, so that the mechanical energy of the fan assembly 17 is converted into electrical energy through the wind turbine generator and stored in the energy storage box 15. A fan assembly 17 electrically connected to the energy storage box 15 through a wire is installed on both sides of the fixing plate 16, a wind turbine is installed inside the fan assembly 17, an extension mechanism is installed inside the protection tube 1, the extension mechanism includes an electric air pump 2 fixedly connected to the surface of the protection tube 1, the output end of the electric air pump 2 is fixedly connected to the air intake pipe 3, the surface of the air intake pipe 3 is fixedly connected to the air bag 4, water is arranged inside the air bag 4 for weighting the protection tube 1, after the air bag 4 is weighted by water, the air bag 4 and the protection tube 1 are more stable when in use, and the wind load performance of the protection tube 1 is further improved; One end of the airbag 4 is fixedly connected to an extension tube 5 which is slidably connected to the inside of the protection tube 1. The surfaces of the extension tube 5 and the airbag 4 are both provided with through grooves 6, which correspond to the power cable. Through the provision of the through grooves 6, the power cable can be plugged into the inside of the protection tube 1, avoiding the airbag 4 and the extension tube 5 from causing movement obstruction to the insertion of the power cable. The airbag 4 and the extension tube 5 are both installed inside the protection tube 1. The two inner walls of the protection tube 1 are fixedly connected to the limit rod 7. Both sides of the surface of the extension tube 5 are provided with guide grooves 8 corresponding to the limit rod 7. The limit rod 7 is slidably connected to the inside of the guide groove 8. The limit rod 7 and the guide groove 8 cooperate with each other to guide the sliding of the extension tube 5, so that the extension tube 5 is more stable when sliding inside the protection tube 1. A threshold is set for the fan assembly 17. When the speed of the fan assembly 17 driven by the wind exceeds the threshold, the electric air pump 2 is started based on the electric energy inside the energy storage box 15, so that it injects external air into the air bag 4 through the air intake pipe 3, causing the air bag 4 to deform, thereby driving the extension tube 5 to slide out of the protection tube 1, so that the extension tube 5 further protects the power cable, thereby further improving the performance of the wind load of the power cable; A cleaning mechanism is installed on the surface of the extension tube 5. The cleaning mechanism includes a sponge 9 fixedly connected to one end of the extension tube 5 and corresponding to the protection tube 1. The inner wall of the sponge 9 fits the power cable. The surface of the sponge 9 is provided with a plug-in groove corresponding to the through groove 6. The sponge 9 fits the inner wall of the protection tube 1. When the extension tube 5 slides, the sponge 9 is synchronously driven to slide on the inner wall of the protection tube 1 to wipe the water on the inner wall of the protection tube 1, thereby preventing the water from affecting the power cable. The two edges of one side of the extension tube 5 are fixedly connected with a tightening spring 10 corresponding to the protection tube 1. The extension tube 5 drives the tightening spring 10 to move, so that the tightening spring 10 fits with a side wall of the protection tube 1 and deforms. Thus, through the interaction force between the tightening spring 10 and the airbag 4, the sponge 9 and the extension tube 5 seal one side of the protection tube 1, thereby preventing the influence of wind and rain on the power cable. A mounting plate 18 is fixedly connected to one side of the protection tube 1, and a guide block 19 is fixedly connected to the upper surface of the mounting plate 18. The setting of the guide block 19 makes the protection cover 20 more stable when sliding on the power cable. The surface of the guide block 19 is slidably connected with a protection cover 20 corresponding to the extension tube 5. The protection cover 20 is made of elastic material, and the surface of the protection cover 20 is provided with an opening corresponding to the power cable. The opening and the elastic setting of the protection cover 20 make it more convenient to install the protection cover 20 on the power cable. When the extension tube 5 slides, the protective cover 20 is pushed to slide on the power cable, which not only improves the protection range of the power cable protective cover on the power cable, but also prevents the protective cover 20 from hindering the movement of the extension tube 5. Thus, through the mutual cooperation of the protective tube 1, the extension tube 5 and the protective cover 20, the wind load performance of the power cable is improved, and the wind resistance effect of the power cable is further improved. Sliding grooves 23 are provided on both sides of the surface of the protective cover 20, and the guide block 19 is slidably connected to the inside of the sliding groove 23. The surface of the protective tube 1 is fixedly connected to a protective shell 21 corresponding to the electric air pump 2. The cleaning mechanism also includes an exhaust pipe 11 fixedly connected to the surface of the airbag 4, and the exhaust pipe 11 is fixedly connected to the inside of the electromagnetic valve 12. When the rotation speed of the fan assembly 17 decreases, the electromagnetic valve 12 is set to discharge the gas in the airbag 4 through the exhaust pipe 11, so that the airbag 4 is reset, thereby resetting the extension tube 5; An annular through-tube 13 is fixedly connected to the surface of the exhaust pipe 11, and a guide tube 14 corresponding to the inner wall of the protective tube 1 is fixedly connected to the surface of the annular through-tube 13 in an annular array. When the gas is discharged through the exhaust pipe 11, the gas enters the interior of the annular through-tube 13 and is discharged through the guide tube 14, so that the gas is blown toward the inner wall of the protective tube 1, so that the water on the inner wall of the protective tube 1 is dried by air, thereby avoiding the water inside the protective tube 1 from contacting the power pull wire and causing the power pull wire to rust, thereby reducing the service life of the power pull wire.

[0020] Specifically, when the multi-protection power cable protective cover is in use: the protective tube 1, the extension tube 5 and the protective cover 20 are installed on the surface of the power cable, and the fan assembly 17 is driven to rotate by natural wind, so that the mechanical energy of the fan assembly 17 is converted into electrical energy through the wind turbine and stored in the energy storage box 15, and a threshold is set for the fan assembly 17. When the speed of the fan assembly 17 driven by the wind exceeds the threshold, the electric air pump 2 is started based on the electrical energy in the energy storage box 15, so that the external air is injected into the air bag 4 through the air inlet pipe 3, so that the air bag 4 is deformed, thereby driving the extension tube 5 to slide out of the protective tube 1, so that the extension tube 5 further protects the power cable; When the extension tube 5 slides, the sponge 9 is synchronously driven to slide on the inner wall of the protection tube 1 to wipe the water on the inner wall of the protection tube 1, thereby preventing the water from affecting the power cable. At the same time, the extension tube 5 drives the pressing spring 10 to move, so that the pressing spring 10 fits with one side wall of the protection tube 1 and deforms. Through the interaction force between the pressing spring 10 and the airbag 4, the sponge 9 and the extension tube 5 seal one side of the protection tube 1, thereby preventing the wind and rain from affecting the power cable. At the same time, when the extension tube 5 slides, the protective cover 20 is pushed to slide on the power cable, which not only improves the protection range of the power cable protective cover on the power cable, but also prevents the protective cover 20 from hindering the movement of the extension tube 5. Thus, through the cooperation of the protective tube 1, the extension tube 5 and the protective cover 20, the wind load performance of the power cable is improved, and the wind resistance effect of the power cable is further improved; When the rotation speed of the fan assembly 17 decreases, the solenoid valve 12 is set to allow the gas in the airbag 4 to be discharged through the exhaust pipe 11, so that the airbag 4 is reset, thereby resetting the extension tube 5. At the same time, when the gas is discharged through the exhaust pipe 11, the gas enters the interior of the annular passage 13 and is discharged through the guide pipe 14, so that the gas is blown to the inner wall of the protective tube 1, so that the water on the inner wall of the protective tube 1 is dried by air, thereby avoiding the water inside the protective tube 1 from contacting the power cable and causing the power cable to rust, thereby reducing the service life of the power cable.

[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
