Abstract
Description
Technical Field
[0001] The invention relates to a carport for parking and charging electric vehicles, and in particular to an intelligent charging carport for electric vehicles and a charging method. Background Art
[0002] At present, carports are important facilities for the storage and charging of electric vehicles, and are used in large quantities. However, in actual use, it is found that when the current carport is used for parking and charging of electric vehicles, on the one hand, there is a lack of comprehensive real-time monitoring of the surrounding environment and personnel when the vehicle is charged and parked, which leads to the easy occurrence of vehicle damage, theft and power theft during parking and charging. At the same time, it is also impossible to timely and effectively discover fire hazards and timely and safely and effectively extinguish the fire point when a fire occurs, and cool down the surrounding environment of the fire point to prevent the spread of the fire and eliminate the collateral damage caused by high temperature to surrounding vehicles and equipment, resulting in the current carport facilities. The safety of electric vehicle parking and charging operations is relatively poor; on the other hand, during charging and vehicle parking, the current carport cannot flexibly adjust the position of the vehicle, resulting in some charging positions being unable to provide charging and parking services for subsequent vehicles due to the obstruction of parked vehicles, resulting in the current carport's insufficient coordination ability for vehicle parking and charging management, which easily leads to the defect that the charging equipment cannot provide charging services due to the obstruction of vehicles, while affecting the flexibility and reliability of charging operations, it also causes a waste of charging equipment resources.
[0003] Therefore, in view of this situation, it is urgent to develop a new electric vehicle charging shed and charging management method to meet the needs of actual use. Summary of the invention

[0015] S2, charging operation. After completing step S1, the charging operation can be carried out. During the charging operation, the electric vehicle to be charged is parked on the carrying tray of the corresponding charging parking space and locked by the positioning frame and positioning lock. Then, after the operator performs identity authentication and charging fee payment operations through the charging pile control interface, the charging pile can charge the vehicle and stop the charging operation after the charging operation is completed. The owner disconnects the vehicle from the charging pile and moves the vehicle out of the charging parking space.
[0016] S3, parking space management, when the vehicle is in the charging state or the vehicle has completed charging but has not been removed from the charging parking space, when the subsequent vehicle is needed, the driving circuit drives the transfer mechanism corresponding to the currently used charging parking space to operate, and the transfer mechanism transfers the charging parking space currently carrying the vehicle to the other side of the positioning plate on the one hand; on the other hand, the unused charging parking space on the other side of the positioning plate is transferred to the current working position, so as to achieve the purpose of vacating the charging parking space and meeting the purpose of real-time charging and flexible adjustment of the charging parking space;
[0017] S4, fire protection management, during charging operations and daily operation and maintenance, the operating status of each charging pile is monitored through monitoring and protection devices, and when a fire is found, the electrical connection between the charging pile and the external circuit is first cut off through the driving circuit, and then the fire extinguishing mechanism is driven to extinguish the fire in time.
[0018] Furthermore, in the step S4, the specific monitoring contents of the monitoring protection device include:
[0019] The monitoring camera of the monitoring protection device monitors the charging operation operators and the operation status of the vehicles and charging piles during the charging operation, and promptly detects safety hazards such as fire, theft and misoperation;
[0020] The temperature and humidity sensors of the monitoring protection device detect the operating environment temperature of the charging pile, and promptly discover potential fire hazards and equipment failure hazards caused by excessively high ambient temperature;
[0021] Use the smoke sensor of the monitoring protection device to timely detect fire hazards and locate the fire point;
[0022] The parking charging operators are monitored through the human body sensor of the monitoring protection device and the monitoring camera;

[0024] Furthermore, when extinguishing the fire in step S4, the fire source is first sprayed directly by the fire extinguisher of the fire extinguishing mechanism, and then the fire water in the water tank is pressurized by the drainage pipe and sprayed with water mist through the sprinkler port. While assisting in extinguishing the fire, it also effectively cools the surrounding equipment and increases the water content, preventing the fire from spreading and high temperature from causing damage to the surrounding equipment.
[0025] The present invention has a simple structure and is flexible and convenient to use. On the one hand, it has strong adaptability to the site and can flexibly adjust the parking position of the vehicle according to the actual needs of the vehicle parking and charging operations, thereby greatly improving the flexibility and convenience of the vehicle parking and charging operations; on the other hand, during vehicle charging, it can effectively realize comprehensive monitoring of factors such as the identity of the charging operator, vehicle information, vehicle position, charging environment and fire hazards, and when a safety accident such as a fire occurs, the circuit can be cut off in time and the fire location can be extinguished.
