DETAILED DESCRIPTION

[0027] 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.

[0028] Example 1

[0029] See also Figures 1 to 4 , which is the first embodiment of the present invention, and this embodiment provides a technical solution: an electric ship charging device with multiple sockets, comprising

[0030] A charger body 1, a side substrate 4 welded and fixed to both side surfaces of the charger body 1, and a plurality of charging sockets 5 arranged on the surface of the side substrate 4;

[0031] And a plurality of cable limiting mechanisms 6 arranged on the side of the side substrate 4 and at the bottom of the charging socket 5, including a U-shaped base 61 welded and fixed on the side of the side substrate 4, a movable side block 62 movably installed on the side of the U-shaped base 61, a rotating block 63 rotatably installed at the end of the movable side block 62, a pressure rod 64 welded and fixed on the side of the rotating block 63, a movable pressure pad 65 installed at the end of the pressure rod 64 and sliding into the inner side of the U-shaped base 61, and a compression pad 66 installed on the inner side of the U-shaped base 61 and corresponding to the movable pressure pad 65. The cable limiting mechanism 6 also includes a strip slide 67 opened on the side of the U-shaped base 61, an inner slider 68 and a spring 69 arranged in the strip slide 67. The end of the inner slider 68 extends to the side of the U-shaped base 61 and is fixed to the movable side block 62. Under the push of the spring 69, the movable pressure pad 65 can continuously clamp the charging cable tightly during daily charging to ensure the plug-in stability of the charging plug and the charging socket 5, thereby ensuring the charging stability. In actual use, The operator can first pull the movable side block 62 sideways to make the inner slide block 68 move sideways to compress the spring 69, and make the rotating block 63, the pressure rod 64 and the movable pressure pad 65 move sideways smoothly until the movable pressure pad 65 moves out of the U-shaped base 61. At this time, the rotating block 63 can be rotated to make the movable pressure pad 65 rotate and move away from the notch of the U-shaped base 61. Then, the charging plug of the electric ship to be charged is inserted into the charging socket 5, and the cable on the charging plug is pushed into the inner side of the U-shaped base 61, and then Then move the movable side block 62 sideways and rotate the rotating block 63 to align the movable pressure pad 65 with the notch of the U-shaped base 61, and then slowly release the movable side block 62. Under the push of the spring 69, the movable side block 62 rebounds with the rotating block 63, the pressure rod 64 and the movable pressure pad 65, and finally the movable pressure pad 65 is pressed on the surface of the cable, and cooperates with the clamping pad 66 to complete the clamping and limiting of the cable, thereby ensuring the plug-in stability of the charging plug above the cable and the charging socket 5, and ensuring the charging stability.

[0032] Among them, a guide rod 671 is also fixed in the strip slide groove 67, and the inner slider 68 is slidably sleeved on the surface of the guide rod 671, so that the inner slider 68 can stably slide in the strip slide groove 67, and at the same time, the spring 69 is also sleeved on the surface of the guide rod 671, so that the spring 69 will not fall off from the strip slide groove 67.

[0033] One end of the spring 69 abuts against the side surface of the inner slide block 68 , and the other end of the spring 69 abuts against the inner wall of the strip-shaped slide groove 67 .

[0034] The inner surfaces of the movable pressure pad 65 and the pressing pad 66 are provided with a plurality of anti-skid grooves, which can improve the stability of the subsequent cable clamping and play an anti-skid effect, and both are made of rubber material.

[0039] The communication and monitoring module realizes communication between modules and connection with an external monitoring system, facilitating remote monitoring and management. The communication and monitoring module conducts data interaction with the external monitoring system through a data upload module and a remote monitoring interface to achieve real - time upload and remote monitoring of charging data. Key components: CAN bus, RS485 serial communication module, network communication module, adopting standardized communication protocols to ensure the reliability and real - time nature of data transmission;

[0040] The safety protection module provides safety protection measures such as lightning protection, over - temperature, over - current, etc. to ensure the stable operation of the system. When the safety protection module detects an abnormal situation, it issues a warning signal through the fault warning module and immediately cuts off the power supply through an automatic power - off device. Key components: lightning protection module, temperature sensor, current sensor, protection relay, with fast response and self - protection functions to prevent safety accidents.

[0041] Among them, a display screen 2 is arranged on the front surface of the charger main body 1.
