Description

[0002] At present, most ports use charging piles to charge small electric ships. The charging piles are generally divided into two types of direct current charging and alternating current charging. The direct current charging is to supply power to the battery pack by adjusting the voltage of the direct current through a rectifier module. This power supply mode can greatly reduce the AC voltage and rectifier equipment in the cabin, thereby saving space. However, due to the low voltage of the direct current charging, it cannot be charged at high power, which greatly affects the charging efficiency. The alternating current charging is to send alternating current to the AC voltage and rectifier equipment on the ship through a cable. This mode can improve the charging power and charging efficiency, but it needs to increase the related equipment for converting alternating current to direct current, thereby occupying a large space in the cabin.

[0003] Due to the inconsistent length of small functional new energy ships, the berthing position is random, and the charging pile is limited by the length and position of the cable.

The vertical arm 25 is composed of a soft connection conductor, such as a soft copper bar, which has good bending and toughness.

[0065] The sliding power connection assembly 31 or the vertical arm 25 is movably connected to the end of the large arm 24. The vertical arm 25 is suspended below the large arm 24 and can swing below the large arm 24 to improve flexibility. When the sliding power connection assembly 31 is arranged at the top end of the vertical arm 25, the sliding power connection assembly 31 is connected with the large arm 24 through a movable joint. When the sliding power connection assembly 31 is arranged at the middle or lower end of the vertical arm 25, the top end of the vertical arm 25 is connected with the large arm 24 through a movable joint.

[0066] In some embodiments, as shown in FIG. 3, the adaptive adjuster 3 further comprises a buffer device 32 configured to be synchronously extended and retracted with the sliding power connection assembly 31. The buffer device 32 can absorb pressure or tension and play a buffering and protection role.

[0067] In some embodiments, as shown in FIG. 3, the sliding contact assembly 31 includes a fixed conductor 311 and a sliding conductor 312 in sliding contact. The mechanical arm 2 is connected to and powered by the fixed conductor 311, and the charging module 4 is connected to and powered by the sliding conductor 312. The fixed conductor 311 and the sliding conductor 312 can maintain contact and power when sliding relative to each other. Specifically, the fixed conductor 311 is connected to and powered by the large arm 24.

[0068] The buffer device 32 can be connected between the fixed conductor 311 and the sliding conductor 312. The buffer device 32 can be a pneumatic buffer, a hydraulic buffer, a spring buffer, etc.

[0069] In the specific embodiment shown in FIG. 3, the adaptive adjuster 3 can be disposed at the top end of the vertical arm 25, and the charging module 4 can be disposed at the bottom end of the vertical arm 25.

[0070] In some embodiments, the position detection device 61 of the active adjuster 6 can use radar to detect the position of the power receiving module 5. The position detection device 61 can be installed on the mechanical arm 2 or on the vehicle.

[0071] In one embodiment shown in FIG. 2, the position detection device 61 is installed on the side of the center column 21. The active adjuster 6 can also use other existing positioning technologies to detect the position of the power receiving module 5.

[0072] In some embodiments, as shown in FIG. 4, the active adjuster 6 further includes a force sensor 62 installed on the luffing drive device 23 for detecting a force signal of the luffing drive device 23. The control unit 7 is electrically connected to the force sensor 62 and receives the force signal.

When the control unit 7 judges that the force signal exceeds the preset value, the control unit 7 sends a control signal to the luffing drive device 23 to actively control the luffing drive device 23 to adjust the pitch angle of the mechanical arm 2, so as to adjust the position of the charging module 4, and make the charging module 4 consistent with the power receiving module 5 in height.

[0074] The control unit 7 can monitor the force of the luffing drive device 23 in real time through the force sensor 62, so as to realize the real-time adjustment of the mechanical arm 2 and adapt to the fluctuation of the ship body following the sea waves.

[0075] When the ship body rises due to the surge fluctuation, the adaptive adjuster 3 is shortened and continuously powered, the vertical arm 25 is deformed by force, and passive adjustment is performed. When the ship body descends due to the surge fluctuation, the vertical arm 25 is stretched and deformed, the length is increased, the adaptive adjuster 3 is stretched and continuously powered, and passive adjustment is performed. When the ship body descends beyond the limit of the vertical arm 25 and the limit of the adaptive adjuster 3, the mechanical arm 2 bears tension, the force of the luffing drive device 23 increases, and the active adjuster 6 controls the luffing drive device 23 to lower the height of the mechanical arm 2 according to the force signal of the force sensor 62, so as to make the charging module 4 adapt to the position of the ship body. At the same time, in the above passive adjustment process, the active adjuster 6 detects the position of the power receiving module 5 in real time through the position detection device 61, and actively adjusts the luffing of the mechanical arm 2 according to the position of the power receiving module 5 to adjust the position of the charging module 4.

[0076] The adjustment functions of the vertical arm 25, the adaptive adjuster 3 and the active adjuster 6 realize the combination of the active adjustment mode and the passive adjustment mode, and guarantee the reliability of power supply and the safety of the equipment.
