Embodiment 1

[0029] figure 1 The structural diagram of a shore power interlocking device provided in Embodiment 1 of the present invention is applicable to the scene where the dock shore power box supplies power to the loads on the ship, such as figure 1 As shown, the shore power interlocking device includes a closing detection module 1 and an opening control module 2;

[0030] The input end of the closing detection module 1 is configured to be connected to the output end of the shore power box 3, and the output signal of the closing detection module 1 is connected to the opening control module 2; the closing detection module 1 is used to detect the shore power voltage of the shore power box and pass the access signal to the opening control module 2.

[0031] The opening control module 2 is arranged between the shore power box 3 and the load 4 with a preset capacity, and is used to cut off the power supply line between the shore power box 3 and the load 4 with a preset capacity according ...

Embodiment 2

[0038] figure 2 It is a schematic structural diagram of a shore power interlocking device provided in Embodiment 2 of the present invention. This embodiment is further refined on the basis of the above embodiments, as shown in figure 2 As shown, optionally, the closing detection module 1 includes: a voltage detection submodule 11 and a controlled switch submodule 12;

[0039] The input end of the voltage detection sub-module 11 is configured to be connected to the output end of the shore power box 3, and the output end of the voltage detection sub-module 11 is connected to the enabling end of the controlled switch sub-module 12;

[0040] The voltage detection sub-module 11 is used to transmit a control signal to the enable terminal of the controlled switch sub-module 12 when the shore power voltage of the shore power box 3 is detected;

[0041] The controlled switch sub-module 12 is used to conduct the signal line according to the control signal, so that the access signal i...

Embodiment 3

[0056] Figure 4 It is a structural schematic diagram of a shore power interlocking device provided in Embodiment 3 of the present invention, as shown in Figure 4 As shown, this embodiment is further refined on the basis of the above embodiments. Specifically, in this embodiment, the output terminal of the closing detection module is connected to the opening control module in a wireless manner. Therefore, the embodiment of the present invention provides In addition to the above-mentioned structure (not to be repeated), the shore power interlocking device should also specifically include:

[0057] When the closing detection module is connected to the opening control module by wireless signals, the closing detection module 1 includes a wireless signal transmitting sub-module 13, and the opening control module 2 includes a wireless signal receiving sub-module 23; the wireless signal transmitting sub-module The module 13 is used to transmit the access signal to the wireless sign...

Abstract

The embodiment of the invention discloses a device for shore power interlocking, which comprises a closing detection module and an opening control module; the input end of the closing detection moduleis configured as an output end in a shore power box , and the output end of the closing detection module is in signal connection with the opening control module; the closing detection module is configured to detect an access signal of the shore power voltage of the shore power box, and transmit the access signal to the opening control module; and the opening control module is disposed between theshore power box and a load of a preset capacity, and is configured to cut off the power supply line between the shore power box and the load of the preset capacity according to the access signal. Theembodiment of the invention can solve the problem that the traditional human factor causes the load of the preset capacity to start, and eliminates the safety hazard of the shore power system from the electrical principle.

Description

technical field [0001] The embodiment of the present invention relates to ship power supply technology, in particular to a shore power interlocking device. Background technique [0002] There are a huge number of ships berthing and loading and unloading in my country's coastal and inland ports every year. With the development of new energy electric ships, higher requirements are put forward for ship power supply technology, especially when ships need to use shore power every time they call at ports to unload cargo. Provides power to assisted living equipment on board. The shore power of electric boats has a capacity of 160A, which can only supply and distribute power to small daily loads, such as household appliances such as rice cookers and induction cookers. For relatively heavy loads exceeding the preset capacity, such as those with a capacity of about 35A Bilge pumps are not suitable to be started by shore power, otherwise the relatively large current will cause violent ...
