TECHNICAL FIELD

[0001] The application relates to the technical field of cable winding and unwinding, and particularly relates to a new energy charging pile cable winding and unwinding device. BACKGROUND

[0002] With the transformation of global energy structure and the rapid development of the new energy automobile industry, the deployment scale and application scenarios of new energy charging piles as the core infrastructure for energy supply of electric vehicles are continuously expanded, and the winding and unwinding state of cables as the key components for realizing power transmission of the charging piles directly affects the use safety, convenience and equipment life of the charging piles. In the process of winding and unwinding the cable, the traditional device causes the cable to be damaged due to friction between the cable and other components, and in the charging process, the cable is exposed to the open air, which causes various impurities such as mud to adhere to the outer wall of the cable, and when the impurities such as mud adhere to the outer wall of the cable for a long time, the risk of corrosion of the cable is further increased. SUMMARY

[0003] The waterproof agent after air drying directly blocks rainwater and dew or car washing splashing water from penetrating into the cable, effectively prevents the internal copper wire of the cable from being short-circuited or electrically leaked, ensures the charging safety, and the waterproof agent can isolate the moisture and dust in the air and the corrosive substances in the external environment, slow down the aging and cracking of the cable sheath, reduce the maintenance cost caused by the damage of the cable, and at the same time, the waterproof agent adhered to the surface of the cable can promote the lubrication of the cable, reduce the abrasion between the cable and other components when the cable is pulled out, and further protect the cable sheath.

[0004] To achieve the above-mentioned purpose, the application provides the following technical scheme: a new energy charging pile cable winding and unwinding device, comprising a charging pile, a wheel disc rotating in the charging pile, a cable wound outside the wheel disc, a gear A rotating at one end of the wheel disc, a guide pipe provided at one end of the gear A, a piston sliding in the guide pipe and driven by the gear A, a liquid storage tank communicated with one end of the guide pipe, and a sponge communicated with the other end of the liquid storage tank. A one-way clutch is connected to one end of the wheel disc, a belt pulley A rotates outside the one-way clutch, an umbrella gear assembly is arranged outside the charging pile and driven by the belt pulley A, and a cleaning sleeve rotates outside the cable and is driven by the umbrella gear assembly. A gear B rotates at the other end of the wheel disc, and a fan blade is connected to one end of the gear B.

[0005] Preferably, a clockwork spring is arranged in the wheel disc, and a plurality of groups of protruding teeth are fixedly connected to the outer sides of both ends of the wheel disc.

[0006] Preferably, gear A meshes with multiple sets of gears A at one end of the wheel disk, and a threaded rod is fixedly connected to one end of gear A. The threaded rod is threadedly connected to the piston, and a guide groove is provided inside the guide tube. The piston is connected to the guide groove.

[0007] Preferably, one end of the guide tube is fixedly connected to a connecting pipe A, and the other end of the connecting pipe A passes through the charging pile and is connected to the liquid storage tank.

[0008] Preferably, a guide ring is installed on the outside of the sponge, and a connecting pipe B is fixedly connected to one side of the liquid storage tank. The other end of the connecting pipe B passes through the charging pile and connects to the guide ring and the sponge.

[0009] Preferably, one end of the wheel is fixedly connected to a connecting shaft, and the other end of the connecting shaft extends outward through the mounting bracket at one end of the wheel and is connected to a one-way clutch. The pulley A is fixedly connected to the one-way clutch.

[0010] Preferably, a belt is fitted inside the pulley A, the other end of the belt extends to the outside of the charging pile, and a pulley B is fitted at the other end of the belt. The pulley B is rotatably connected to the outer wall of the charging pile.

[0011] Preferably, one end of the pulley B is fixedly connected to a bevel gear assembly, the other end of the bevel gear assembly is engaged with bevel teeth, the bevel teeth are fixedly connected to the outside of the cleaning sleeve, and the cleaning sleeve is rotatably connected to the outside of the charging pile.

[0012] Preferably, gear B meshes with multiple sets of convex teeth at the other end of the wheel, and one end of gear B is fixedly connected to a rotating shaft, the other end of the rotating shaft is connected to a fan blade, and a through hole is opened inside the charging pile, with the fan blade located inside the through hole.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a dried waterproofing agent to directly prevent rainwater, dew, or splashes from car washes from seeping into the cable, effectively preventing short circuits or leakage in the internal copper wires, ensuring charging safety. The waterproofing agent also isolates moisture, dust, and corrosive substances from the air, slowing down the aging and cracking of the cable sheath, reducing repair costs caused by cable damage. At the same time, the waterproofing agent adhering to the cable surface promotes cable lubrication, reducing wear between the cable and other components when pulling it out, making the cable laying process smoother, and further protecting the cable sheath.

[0014] When the cleaning sleeve rotates, it generates friction with impurities such as mud, sand, and leaves on the outer wall of the cable, effectively peeling off solidified or attached impurities and preventing impurity residue. At the same time, the inner diameter of the cleaning sleeve is slightly larger than the outer diameter of the cable, so it does not directly rub against the cable surface during rotation. This not only prevents wear on the outer wall of the cable due to cleaning operations, but also effectively ensures the integrity of impurity removal and prevents the risk of cable corrosion caused by impurities trapped between the cables.

[0015] This invention accelerates the airflow inside the charging pile by having the fan blades rotate synchronously with the retraction and extension of the wheel, thus expelling moisture in a timely manner, promoting airflow, and preventing internal components from being damaged by moisture. At the same time, the continuous airflow breaks the stagnant and humid environment inside the charging pile, reducing the possibility of insects inhabiting and bacteria and mold growing, and protecting the cleanliness of the equipment's interior.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Reference Figures 1-7 The present invention provides a new energy charging pile cable winding and unwinding device, including a charging pile 1, a rotating wheel 3 inside the charging pile 1, a cable 2 being wound up on the outside of the wheel 3, a gear A5 rotating at one end of the wheel 3, a guide tube 7 being provided at one end of the gear A5, a piston 8 driven by the gear A5 sliding inside the guide tube 7, a liquid storage tank 10 being connected at one end of the guide tube 7, and a sponge 12 being connected at the other end of the liquid storage tank 10. One end of the wheel 3 is connected to a one-way clutch 14, and a pulley A15 rotates on the outside of the one-way clutch 14. A bevel gear assembly 18 driven by the pulley A15 is provided on the outside of the charging pile 1. A cleaning sleeve 20 driven by the bevel gear assembly 18 rotates on the outside of the cable 2. The other end of the wheel 3 has a rotating gear B21, and one end of the gear B21 is connected to a fan blade 23.

[0020] In an optional embodiment, a spring is provided inside the wheel 3, and multiple sets of protruding teeth 4 are fixedly connected to the outer sides of both ends of the wheel 3. When using the device, the operator pulls the charging gun to gradually pull the cable 2 out of the charging pile 1. When the cable 2 is pulled out, it will drive the wheel 3 to rotate synchronously. When the wheel 3 rotates, it will compress the spring inside the wheel 3. After charging is completed, the operator pulls out the charging gun. At this time, the spring will automatically drive the wheel 3 to rotate. When the wheel 3 rotates, it will automatically wind the cable 2 on the outer side of the wheel 3.

[0021] In an optional embodiment, gear A5 meshes with multiple sets of gears A5 at one end of the wheel 3, and a threaded rod 6 is fixedly connected to one end of gear A5. The threaded rod 6 is threadedly connected to the piston 8. A guide groove is provided inside the guide tube 7, and the piston 8 is connected to the guide groove. As described above, when the cable 2 is pulled out, the wheel 3 will drive gear A5 to rotate through the protruding teeth 4 on the outer side of the wheel 3. When gear A5 rotates, it will drive the threaded rod 6 to rotate. When the threaded rod 6 rotates, it will drive the piston 8 to move to one end inside the guide tube 7. When the piston 8 moves, it will compress gas into one end of the guide tube 7. When the wheel 3 automatically winds up the cable 2, the wheel 3 will drive the gear A5 to rotate again. When the gear A5 rotates, it will drive the piston 8 to slide and reset inside the guide tube 7.

[0022] In an optional embodiment, one end of the guide tube 7 is fixedly connected to a connecting tube A9, and the other end of the connecting tube A9 passes through the charging pile 1 and is connected to the liquid storage tank 10. As described above, the gas entering the rear end of the guide tube 7 will enter the interior of the connecting tube A9. After the gas enters the interior of the connecting tube A9, the connecting tube A9 will transport the gas to the interior of the liquid storage tank 10. The liquid storage tank 10 stores a waterproofing agent. After the gas enters the interior of the liquid storage tank 10, the gas will squeeze a small amount of waterproofing agent into the interior of the connecting tube B11.

[0023] In an optional embodiment, a guide ring is installed on the outside of the sponge 12, and a connecting pipe B11 is fixedly connected to one side of the liquid storage tank 10. The other end of the connecting pipe B11 passes through the charging pile 1 and the guide ring and connects to the sponge 12. After the waterproofing agent enters the interior of the connecting pipe B11, the connecting pipe B11 will deliver the waterproofing agent to the sponge 12. After the waterproofing agent comes into contact with the sponge 12, the sponge 12 will gradually become wet. At this time, when the cable 2 is pulled out, it will come into contact with the sponge 12. Then, the sponge 12, which is wetted by the waterproofing agent, will apply the waterproofing agent to the surface of the cable 2. After the cable 2 comes into contact with the outside world, the waterproofing agent will gradually dry. After the waterproofing agent dries, a thin film will form on the surface of the cable 2. Then, when the cable 2 is pulled out for charging, the wind will... The dried waterproofing agent protects the outer surface of cable 2. Each time the user pulls out cable 2, the waterproofing agent adheres to the surface of cable 2 and is pulled out, thus preventing the waterproofing agent from failing due to prolonged use. The dried waterproofing agent directly blocks rainwater, dew, or splashes from car washes from seeping into the interior of cable 2, effectively preventing short circuits or leakage in the copper wires inside cable 2, ensuring charging safety. The waterproofing agent also isolates moisture, dust, and external corrosive substances in the air, slowing down the aging and cracking of the cable 2's outer sheath, reducing repair costs caused by cable 2 damage. At the same time, the waterproofing agent adhering to the surface of cable 2 promotes lubrication of cable 2, reducing wear between cable 2 and other components when pulled out, making the cable release process smoother, and further protecting the outer sheath of cable 2.

[0024] In an optional embodiment, a connecting shaft 13 is fixedly connected to one end of the wheel 3, and the other end of the connecting shaft 13 extends outward through the mounting bracket at one end of the wheel 3 and is connected to a one-way clutch 14. The pulley A15 is fixedly connected to the one-way clutch 14. During the cable feeding and reeling process, the rotation of the wheel 3 will synchronously drive the connecting shaft 13 to rotate. When the wheel 3 drives the connecting shaft 13 to rotate during cable feeding, the connecting shaft 13 will not drive the one-way clutch 14 to rotate. After charging is completed, as the wheel 3 gradually retracts the cable 2, the connecting shaft 13 will rotate in the opposite direction of cable feeding. At this time, the connecting shaft 13 will drive the one-way clutch 14 to rotate synchronously. When the one-way clutch 14 rotates synchronously, it will synchronously drive the pulley A15 to rotate.

[0025] In an optional embodiment, a belt 16 is fitted inside the pulley A15, and the other end of the belt 16 extends to the outside of the charging pile 1. A pulley B17 is fitted to the other end of the belt 16, and the pulley B17 is rotatably connected to the outer wall of the charging pile 1. As described above, when the pulley A15 rotates, it will synchronously drive the pulley B17 to rotate through the belt 16.

[0026] In an optional embodiment, one end of the pulley B17 is fixedly connected to a bevel gear assembly 18, and the other end of the bevel gear assembly 18 is engaged with a bevel gear 19. The bevel gear 19 is fixedly connected to the outside of the cleaning sleeve 20, and the cleaning sleeve 20 is rotatably connected to the outside of the charging pile 1. When the pulley B17 rotates, it synchronously drives the bevel gear assembly 18 to rotate. When the bevel gear assembly 18 rotates, it synchronously drives the bevel gear 19 to rotate. When the bevel gear assembly 18 rotates, it synchronously drives the cleaning sleeve 20 to rotate. The inner diameter of the cleaning sleeve 20 is slightly larger than the outer diameter of the cable 2, so that no friction is generated on the outer surface of the cable 2 when the cleaning sleeve 20 rotates. When the cleaning sleeve 20 comes into contact with impurities such as mud or leaves attached to the outer surface of the cable 2, the cleaning sleeve 20 will generate friction. The rotation of the cleaning sleeve 20 will generate a certain friction between the cleaning sleeve 20 and impurities such as leaves, thereby better peeling off the leaves or other impurities attached to the outer wall of the cable 2. This prevents the cleaning sleeve 20 from directly contacting the impurities and failing to effectively peel off the solidified impurities such as mud and sand, which would increase the risk of corrosion of the outer wall of the cable 2. Thus, when the cleaning sleeve 20 rotates, it can generate friction with the mud, sand, leaves and other impurities on the outer wall of the cable 2, effectively peeling off the solidified or attached impurities and preventing impurities from remaining. At the same time, the inner diameter of the cleaning sleeve 20 is slightly larger than the outer diameter of the cable 2, so it does not directly rub against the surface of the cable 2 when rotating. This not only prevents wear on the outer wall of the cable 2 caused by the cleaning operation, but also effectively ensures the integrity of the impurity removal and prevents the risk of corrosion of the cable 2 caused by impurities trapped between the cables 2. Because there is a certain gap between the cleaning sleeve 20 and the cable 2, and the inside of the cleaning sleeve 20 is made of elastic material, when the cable 2 is pulled out, the rotation of the wheel 3 will not drive the one-way clutch 14 to rotate. Therefore, when the cable 2 is pulled out, the non-rotating cleaning sleeve 20 can promote the uniformity of the waterproofing agent on the surface of the cable 2 when the outer wall of the cable 2 coated with the waterproofing agent comes into contact with the inner wall of the cleaning sleeve 20 without peeling off the waterproofing agent.

[0027] In an optional embodiment, gear B21 meshes with multiple sets of teeth 4 at the other end of the wheel 3, and a rotating shaft 22 is fixedly connected to one end of gear B21. The other end of the rotating shaft 22 is connected to the fan blade 23. A through hole is provided inside the charging pile 1, and the fan blade 23 is located inside the through hole. When the wheel 3 unwinds and winds the cable 2, the teeth 4 at the other end of the wheel 3 drive gear B21 to rotate. When gear B21 rotates, it drives the fan blade 23 to rotate through the rotating shaft 22. When the fan blade 23 rotates, it will... The fan blades 23 rotate synchronously with the retraction and extension of the wheel 3, thereby accelerating the airflow inside the charging pile 1, expelling moisture, and preventing internal components from being damaged by dampness. At the same time, the continuous airflow breaks the stagnant and damp environment inside the charging pile 1, reducing the possibility of insects inhabiting and bacteria and mold growing, and protecting the cleanliness of the equipment.

[0028] Working principle: When using the device, the operator pulls the charging gun to gradually pull the cable 2 out of the charging pile 1. When the cable 2 is pulled out, it will drive the wheel 3 to rotate. When the wheel 3 rotates, it will compress the spring inside the wheel 3. When cable 2 is pulled out, the wheel 3 will drive gear A5 to rotate through the protruding teeth 4 on the outer side of the wheel 3. When gear A5 rotates, it will drive threaded rod 6 to rotate. When threaded rod 6 rotates, it will drive piston 8 to move to one end inside guide tube 7. When piston 8 moves, it will compress gas into one end of guide tube 7. When the wheel 3 automatically rewinds cable 2, the wheel 3 will drive gear A5 to rotate again. When gear A5 rotates, it will drive piston 8 to slide and reset inside guide tube 7 again. The gas entering the rear end of the guide tube 7 will enter the interior of the connecting tube A9. After the gas enters the interior of the connecting tube A9, the connecting tube A9 will transport the gas to the interior of the liquid storage tank 10. The liquid storage tank 10 contains waterproofing agent. After the gas enters the interior of the liquid storage tank 10, the gas will squeeze a small amount of waterproofing agent into the interior of the connecting tube B11. After the waterproofing agent enters the connecting tube B11, the connecting tube B11 will deliver the waterproofing agent to the sponge 12. After the waterproofing agent comes into contact with the sponge 12, the sponge 12 will gradually become wet. At this time, when the cable 2 is pulled out, it will come into contact with the sponge 12. Then, the sponge 12, which is wetted by the waterproofing agent, will apply the waterproofing agent to the surface of the cable 2. After the cable 2 comes into contact with the outside, the waterproofing agent will gradually dry. After the waterproofing agent dries, a film will form on the surface of the cable 2. When the cable 2 is pulled out for charging, the dried waterproofing agent will protect the outside of the cable 2. And every time the user pulls out the cable 2, there will be waterproofing agent adhering to the surface of the cable 2. During the wire feeding and reeling processes, the rotation of the wheel 3 synchronously drives the connecting shaft 13 to rotate. When the wheel 3 drives the connecting shaft 13 to rotate during wire feeding, the connecting shaft 13 will not drive the one-way clutch 14 to rotate. After charging is completed, as the wheel 3 gradually retracts the cable 2, the connecting shaft 13 will rotate in the opposite direction of wire feeding. At this time, the connecting shaft 13 will drive the one-way clutch 14 to rotate synchronously. When the one-way clutch 14 rotates synchronously, it will synchronously drive the pulley A15 to rotate. When the pulley A15 rotates, it will synchronously drive the pulley B17 to rotate through the belt 16. When pulley B17 rotates, it will synchronously drive bevel gear assembly 18 to rotate. When bevel gear assembly 18 rotates, it will synchronously drive bevel gear 19 to rotate. When bevel gear assembly 18 rotates, it will synchronously drive cleaning sleeve 20 to rotate. The inner diameter of cleaning sleeve 20 is slightly larger than the outer diameter of cable 2. Therefore, when cleaning sleeve 20 rotates, it will not generate friction on the outer surface of cable 2. When cleaning sleeve 20 comes into contact with impurities such as mud or leaves attached to the outer surface of cable 2, the rotation of cleaning sleeve 20 will generate a certain friction between cleaning sleeve 20 and impurities such as leaves, thereby better peeling off the leaves or other impurities attached to the outer wall of cable 2. After charging is complete, the user pulls out the charging gun. At this time, the spring will automatically drive the wheel 3 to rotate. When the wheel 3 rotates, the cable 2 will be automatically wound up on the outside of the wheel 3. When the wheel 3 unwinds and rewinds the cable 2, the tooth 4 at the other end of the wheel 3 drives the gear B21 to rotate. When the gear B21 rotates, it drives the fan blade 23 to rotate through the rotating shaft 22. When the fan blade 23 rotates, it promotes the airflow inside the charging pile 1, thereby expelling the moisture inside the charging pile 1 and preventing the possibility of insects and bacteria growing if the air inside the charging pile 1 does not circulate for a long time.
