The other end of the air charging pipe 9 is fixedly connected to the air outlet end of the blower 8, and an electric ball valve 11 is provided at one end of the air charging pipe 9.

[0027] Through the setting of the blower 8, the operation of the blower 8 can blow the outside air into the inner cavity of the inflatable ring 16, and the volume of the inflatable ring 16 can expand. The inflatable ring 16 can be used to fill the gap between the DC charging pile cable 3 and the cable inlet / outlet hole 17, seal the cable inlet / outlet hole 17, and prevent outside moisture, dust, etc. from entering the inner cavity of the device body 1 through the cable inlet / outlet hole 17, which is convenient for storing the DC charging pile cable 3.

[0028] An exhaust valve 19 is provided at one end of the air charging pipe 9. The exhaust valve 19 is located between the electric ball valve 11 and the inflatable ring 16. Through the setting of the exhaust valve 19, it is convenient to deflate the inflatable ring 16.

[0029] On the outer side of the cable inlet / outlet hole 17, a cold air spray ring 4 is fixedly connected. On the inner walls of the cold air spray ring 4, rollers 15 are movably connected.

On one side of the inner cavity of the cold air spray ring 4, an air inlet pipe 10 is fixedly connected. The other end of the air inlet pipe 10 is fixedly connected to the air outlet end of the blower 8. An electric ball valve 11 is provided at one end of the air inlet pipe 10.

The sprayed hot air blows onto the DC charging pile cable 3, which can increase the temperature of the surface of the DC charging pile cable 3, facilitating the rollers 15 to straighten the DC charging pile cable 3. And the temperature of the hot air is between 40 degrees and 50 degrees, which can be selected according to requirements and is not limited here.

[0032] Through the above description, it can be seen that during the pulling out process of the DC charging pile cable 3, the combined use of the rollers 15 and the hot air can straighten the DC charging pile cable 3, facilitating the use of the DC charging pile cable 3.

[0033] A fixed roller 5 is movably connected in the inner cavity of the device body 1. On one side of the inner cavity of the device body 1 far from the fixed roller 5, a hydraulic telescopic rod 6 is fixedly connected. At the top of the hydraulic telescopic rod 6, a connecting sleeve 18 is fixedly connected. One end of the connecting sleeve 18 near the fixed roller 5 is movably sleeved with a lifting roller 7. The fixed roller 5 and the lifting roller 7 are arranged alternately, and the bottom of the fixed roller 5 is in contact with the DC charging pile cable, and the top of the lifting roller 7 is in contact with the DC charging pile cable.

[0034] By providing the hydraulic telescopic rod 6, the telescoping of the hydraulic telescopic rod 6 can change the position of the lifting roller 7 fixedly connected thereto. When the lifting roller 7 rises, the lifting roller 7 can lift the DC charging pile cable 3, causing the DC charging pile cable 3 to be distributed in an S shape within the device body 1. This device realizes the storage of the DC charging pile cable 3. When the lifting roller 7 moves downward, the DC charging pile cable 3 can be pulled out.

[0035] When the device stores the DC charging pile cable 3, the electric ball valve 11 is in a closed state to prevent external moisture from entering the inner cavity of the device body 1 through the blower 8.

[0036] All the electrical components involved in this application are of the prior art. Those skilled in the art understand their connection methods. Through those skilled in the art, all the electrical components in this application are connected to their adapted power sources through wires, and a suitable controller is selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, refer to the following description. The electrical connection is completed in the order of the working sequence of each electrical component. Its detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of electrical control will be given.

[0037] In summary: When using this DC charging pile cable automatic storage device, fix the device at a suitable position of the DC charging pile in the prior art. The position of the DC charging pile cable 3 within the device body 1 is as shown in the accompanying drawings of the specification. Figure 1 For example, Figure 1 In, the right end of the DC charging pile cable 3 is electrically connected to the DC charging pile, and the right end of the DC charging pile cable 3 is connected to the charging gun. When the DC charging pile cable 3 is stored, its shape within the device body 1 is as Figure 5 shown. When the DC charging pile cable 3 needs to be used, the exhaust valve 19 is in an open state, and the gas within the inflation ring 16 can be discharged through the exhaust valve 19 until all the gas within the inflation ring 16 is discharged, and the exhaust valve 19 is in a re-closed state. The blower 8 operates, and the operation of the blower 8 causes external air to be blown into the inner cavity of the hot air spray ring 12, and the electric heating wire mesh within the air inlet pipe 2 is in an energized state. During the process of air passing through the electric heating wire mesh, the air is heated, and the hot air is sprayed onto the outer surface of the DC charging pile cable 3 through the nozzle 14 connected to the hot air spray ring 12 to heat the DC charging pile cable 3. The hydraulic telescopic rod 6 drives the lifting roller 7 to move downward to release the restriction on the DC charging pile cable 3, and the user can pull the cable outward. During the process of pulling the DC charging pile cable 3 outward, the roller 15 straightens the DC charging pile cable 3 to facilitate the use of the DC charging pile cable 3.

[0038] After charging is completed, when the DC charging pile cable 3 needs to be stored, the blower 8 blows the outside air into the inner cavity of the cold air spray ring 4, and the air in the cold air spray ring 4 is ejected through the nozzles 14 connected thereto. The ejected air flow blows off the impurities adhering to the surface of the DC charging pile cable 3, facilitating the storage of the DC charging pile cable 3. The hydraulic telescopic rod 6 drives the lifting roller 7 to move upward, and the upward movement of the lifting roller 7 can lift the DC charging pile cable 3. The exposed part of the DC charging pile cable 3 can automatically enter the inner cavity of the device body 1. After the DC charging pile cable 3 is stored, the blower 8 blows air into the inner cavity of the inflation ring 16, and the inflation ring 16 inflates and expands to seal the cable inlet and outlet hole 17, preventing the outside moisture from entering the inner cavity of the device body 1 and facilitating the storage of the DC charging pile cable 3.
