Description

Technical Field

[0001] The invention relates to a ship charging technology, and in particular to a connection structure for shore-based ship charging. Background Art

[0002] As a practical renewable energy, electric energy has been accelerating its development in the power field in recent years. In addition to automobiles, cruise ships have also begun to use electricity as at least an auxiliary power source.

[0003] For this reason, some power supply systems for postal routes have also been produced. However, unlike oil supply, the purpose of replenishing ships at sea is to speed up the replenishment speed and thus increase the voyage. However, because the replenishment speed of electricity is not enough, the current power replenishment usually adopts the shore-based power supply method. For example, Chinese patent CN 202455277U discloses a medium- and low-voltage ship shore power supply, including a phase-shifting transformer, a frequency conversion power supply, an LC filter circuit, and an output switch cabinet. The primary winding of the phase-shifting transformer is directly connected to the busbar grid through the input switch cabinet, the secondary winding of the phase-shifting transformer is connected to the input end of the frequency conversion power supply, the AC output end of the frequency conversion power supply is connected to the LC filter circuit, and the output end of the LC filter circuit is connected to the output switch cabinet to realize high-voltage three-phase 60Hz AC output. However, the improvements of the existing Ganji power supply system, including the low-voltage ship shore power supply, are concentrated on the power supply circuit, and few improvements are made in the connection section. When connecting to the charging interface of the ship, precise alignment needs to be achieved in advance, and the docking efficiency is not high. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a connection structure for charging shore-based ships.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A connection structure for shore-based ship charging, comprising a cable connector and a ship charging interface, wherein the input end of the cable connector is connected to a shore-based power supply via a cable, and the output end is connected to the ship charging interface, wherein the ship charging interface is arranged on the ship, the cable connector is provided with an electromagnet, and the ship charging interface is provided with a soft magnetic body for being adsorbed by the electromagnet.

[0007] The ship is provided with a ship charging circuit, the ship charging interface is provided with a first switch for turning on and off the ship charging circuit, and the cable connector is provided with a first pressing portion for toggling the first switch when the cable connector and the ship charging interface are engaged.

[0008] The cable connector is provided with a second switch for turning on and off the electromagnet and connecting and disconnecting the cable, and the ship charging interface is provided with a second pressing portion for toggling the second switch when the cable connector and the ship charging interface are engaged.

[0009] The second switch includes a conducting part for selectively connecting the electromagnet power supply circuit or the cable power supply circuit, and a telescopic part for driving the conducting part to connect the electromagnet power supply circuit or the cable power supply circuit under the pressing of the second pressing part.

[0010] The telescopic part and the conducting part are connected via a linkage rod.

[0011] The cable connector is arranged on the cable car.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1) The connection between the ship charging port and the cable connector is guided by magnetic attraction, which reduces the difficulty of alignment during connection and improves the efficiency of charging connection.

[0014] 2) The electromagnet and the cable are turned on and off by the second switch. The action of the second switch depends on the docking action, which is convenient for timely closing the electromagnet during normal charging and improving the charging quality.

[0015] 3) The conducting part selectively connects to the electromagnet power supply circuit or the cable power supply circuit, thereby simplifying the circuit structure and improving the switching efficiency.

[0016] 4) The telescopic part and the conducting part are connected by a linkage rod, which has high stability. BRIEF DESCRIPTION OF THE DRAWINGS

The input end of the cable connector 1 is connected to the shore-based power supply through a cable, and the output end is connected to the ship charging interface 2. The ship charging interface 2 is arranged on the ship. The cable connector 1 is provided with an electromagnet 3, and the ship charging interface 2 is provided with a soft magnetic body 4 for being adsorbed by the electromagnet 3. By magnetically guiding the connection between the ship charging interface 2 and the cable connector 1, the difficulty of alignment during connection is reduced, and the efficiency of charging connection is improved.

[0022] A ship charging circuit is provided on the ship, a first switch for turning on and off the ship charging circuit is provided on the ship charging interface 2, and a first pressing portion for toggling the first switch when the cable connector 1 and the ship charging interface 2 are engaged is provided on the cable connector 1.

[0023] The cable connector 1 is provided with a second switch for turning on and off the electromagnet 3 and connecting and disconnecting the cable, and the ship charging interface 2 is provided with a second pressing portion for toggling the second switch when the cable connector 1 and the ship charging interface 2 are engaged. The electromagnet 3 and the cable are turned on and off by the second switch, and the action of the second switch depends on the action of docking, so that the electromagnet 3 is turned off in time during normal charging, thereby improving the charging quality.

[0024] like Figure 2 As shown, the second switch includes a conducting part 5 for selectively connecting the power supply circuit of the electromagnet 3 or the cable power supply circuit, and a telescopic part 6 for driving the conducting part 5 to connect the power supply circuit of the electromagnet 3 or the cable power supply circuit under the pressing of the second pressing part.
