As an embodiment of the present invention, the controller 5 is controlled by an external input signal; during operation, as the controller 5 is specialized, the operation controller 5 may need to preview the operation flow, which is not beneficial to the operation of a vehicle owner, after the connection between the mobile phone and the controller 5, the controller 5 is controlled by the mobile phone to control the electrifying condition of the electromagnet 43, so that the controller 5 is prevented from being controlled manually, the controller 5 is controlled by a human-computer interaction interface, operators can be guided to operate, the operation is relatively simple, the operation controller 5 is omitted, and the operation step is simplified.
The specific working procedure is as follows:
when the electromagnet 43 is controlled by the controller 5 to lose power supply, the electromagnet 43 is not attracted by the iron metal ring 31 outside the cable 3, the electromagnet 43 is pushed to the cable 3 under the action of the telescopic rod 42 on the base 41, the electromagnet 43 and the base 41 are not clamped with the cable 3, at the moment, the cable 3 can be pulled out of the charging pile body 1 easily by manpower, then when the cable 3 needs to be retracted, the traction mechanism 2 is started to retract the cable 3, meanwhile, the electromagnet 43 is controlled by the controller 5 to be electrified, the magnetism of the electromagnet 43 is enough to overcome the elasticity of the telescopic rod 42, namely, when the electromagnet 43 is attracted to move, the telescopic rod 42 generates a force which resists the movement, but the movement of the electromagnet 43 cannot be limited, and after the cable 3 is pulled into the charging pile body 1 continuously by the traction mechanism 2, when the part of the cable 3 sleeved with the iron metal ring 31 enters the fastening mechanism 4, the electromagnet 43 moves towards the right through the attraction force of the iron metal ring 31 to the electromagnet 43, the electromagnet 43 and the base 41 limit the cable 3, the ejector rod 44 moves towards the right along with the electromagnet 43 driving the ejector rod 44 to contact with the top of the base 41, the contact switch for controlling the traction mechanism 2 is arranged at the top of the base 41, after the ejector rod 44 contacts the contact switch, the traction mechanism 2 stops running and does not pull the cable 3, at the moment, the cable 3 is clamped by the action of the electromagnet 43 and the base 41, so that the cable 3 cannot slide down under the action of self gravity, simultaneously, the cable 3 is retracted into the charging pile body 1, the cable 3 is prevented from being damaged in the surface due to external friction with the ground, in addition, the traction mechanism 2 is controlled by the fastening mechanism 4, the cable 3 is prevented from being pulled by the transition of the traction mechanism 2, so that the cable 3 is completely retracted into the charging pile main body 1, the cable 3 is not easy to be pulled out for charging, and the effect of protecting the cable 3 and facilitating the subsequent charging is achieved; when the traction mechanism 2 is used for recovering the cable 3, the charging pile main body 1 can vibrate to drive the rubber rod 6 to generate polarization, the rubber rod 6 is in direct contact with the plastic cylinder 7, friction is generated in the vibration engineering of the rubber rod 6, the rubber rod 6 and the plastic cylinder 7 are both insulators, electric charges are generated by friction of the rubber rod 6 and the plastic cylinder 7, when the traction mechanism 2 is used for retracting the externally connected cable 3, dust attached to the surface of the cable 3 is adsorbed by static charges on the surface of the plastic cylinder 7 due to the fact that the plastic cylinder 7 is relatively close to the cable 3, and the tiny dust can only be attracted due to weak static attraction, so that the cable 3 cannot be attracted to move towards the plastic cylinder 7, namely the attractive force of the plastic cylinder 7 cannot influence the clamping process of the cable 3, and the effect of ensuring the cleanliness of the cable 3 and the cleanliness of the interior of the charging pile main body 1 is achieved; static electricity is generated through friction between the rubber rod 6 and the plastic cylinder 7 to adsorb dust, through holes 71 are formed in the surface of the plastic cylinder 7, and the dust adsorbed on the surface of the plastic cylinder 7 is extracted through the through holes 71 by an external air extractor at the bottom, so that the problem that the dust is accumulated in the charging pile main body 1 and the circuit use of the charging pile main body 1 is influenced is avoided; the through hole 71 is used for sucking dust into the plastic barrel 7, when the through hole 71 is in a round table shape, the aperture on the outer wall of the plastic barrel 7 is larger than the aperture on the inner wall of the plastic barrel 7, and when the transition circular arc is formed in the aperture on the outer wall of the plastic barrel 7, the dust easily enters into the plastic barrel 7, so that the dust cleaning efficiency is improved.
Experiments prove that in order to detect the life prolonging effect of the cable of the charging pile, the staff performs experiments on the existing charging pile and the charging pile provided by the invention, selects two mechanical arms with synchronous movement rules, respectively grabs the cable of the existing charging pile and the cable provided by the invention, has the same cable diameter of the two devices, has the cable diameter of 10cm, and then the mechanical arms continuously stretch and relax instructions, compares the cable of the existing charging pile and the cable skin damage degree provided by the invention, namely records the cable surface diameter loss, measures the dimension after the cable is tested, and then subtracts the dimension after the measurement from the original dimension to obtain the diameter loss;
stretching and loosening experimental equipment by a mechanical arm at the stretching and loosening rate of 1000 times/h, measuring the cable diameters of two charging pile cables 1h,3h,6h and 12h respectively by using a screw micrometer, and obtaining diameter loss data by subtracting a measured value from the original diameter of the cable by using 10cm to be summarized into a table, wherein sixteen groups of experiments are respectively carried out on each experimental equipment, and the lower block diagram is the average diameter loss of the charging pile in the prior art and the charging pile improved by the invention in 1h,3h,6h and 12 h;
according to the block diagram, the figures 5 and 6, the charging pile provided by the invention can be directly retracted after the cable is used, so that the cable is prevented from being dragged on the ground, the abrasion loss of the cable skin is effectively reduced, and the charging pile has remarkable progress compared with the prior art.
