Description

Technical Field

[0001] This utility model relates to the field of ship control technology, and in particular to a split-type wind and oil remote switching control system. Background Technology

[0002] The main propulsion of a ship refers to the energy system that provides the main energy to the ship, such as diesel engines. The auxiliary propulsion refers to the energy system that supplements the energy supply, such as wind and solar power. The auxiliary propulsion can supplement the electrical energy when the main propulsion supply is unstable, thereby reducing the probability of ship failure due to energy instability.

[0003] A search revealed that Chinese invention patent application CN202410855420.1 discloses an automatic control system for switching between main and auxiliary power in ships, relating to the field of ship power switching systems. The system includes a main power system, an auxiliary power system, a load system, and a central control system. The central control system is electrically connected to both the main power system and the auxiliary power system. The main power system includes a diesel generator set, and the auxiliary power system includes a wind turbine generator and a power battery. The central control system includes a battery charge control system, a wind power performance analysis system, and a diesel generator performance analysis system. The wind power performance analysis system includes a wind power control module and a wind power stability analysis module. This invention avoids the situation where excessively high battery charge prevents the wind turbine generator and diesel generator set from supplying power to the power battery, thus avoiding energy waste, while ensuring stable battery charge levels.

[0004] like Figure 1 As shown, most existing ship wind and oil remote switching systems are integrated and lack redundant wiring. If a ship experiences an electrical fault in a single switchboard or device, a fire, a single circuit fault, or a short circuit, all wind turbines and oil lines will be shut down, resulting in a complete power outage and loss of power, posing a safety hazard. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a split-type remote control system for wind and oil pumps, which addresses the above-mentioned deficiencies of the prior art by adopting redundant circuits and a split design. This system solves the problems of all fans and oil pumps stopping due to a single circuit failure or short circuit, and the problem of all fans and oil pumps stopping when a single power distribution board fails.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A split-type remote control system for wind and oil pumps includes a main distribution board and a DC distribution board electrically connected to the main distribution board. The main distribution board is equipped with an isolating switch, and a plurality of emergency shut-off switches for wind turbines and oil pumps electrically connected to the isolating switches are also provided on the main distribution board. The DC distribution board is equipped with a plurality of remote shut-off buttons, and each of the emergency shut-off switches for wind turbines and oil pumps is electrically connected to two of the remote shut-off buttons respectively.

[0011] Preferably, the first inner passageway remote cut-off button and the second front cockpit remote cut-off button are both electrically connected to the first mechanical compartment fan emergency cut-off switch; the second inner passageway remote cut-off button and the third front cockpit remote cut-off button are both electrically connected to the first air conditioning compartment fan emergency cut-off switch; the third inner passageway remote cut-off button and the sixth front cockpit remote cut-off button are both electrically connected to the second mechanical compartment fan emergency cut-off switch; and the fourth inner passageway remote cut-off button and the seventh front cockpit remote cut-off button are both electrically connected to the second air conditioning compartment fan emergency cut-off switch.

[0012] Preferably, the remote cut-off button for the first propeller compartment outlet and the remote cut-off button for the first bridge are both electrically connected to the emergency cut-off switch for the first propeller compartment oil pump; the remote cut-off button for the first engine room opening and the remote cut-off button for the fourth bridge are both electrically connected to the emergency cut-off switch for the first engine room oil pump; the remote cut-off button for the second propeller compartment outlet and the remote cut-off button for the fifth bridge are both electrically connected to the emergency cut-off switch for the second propeller compartment oil pump; and the remote cut-off button for the second engine room opening and the remote cut-off button for the eighth bridge are both electrically connected to the emergency cut-off switch for the second engine room oil pump.

[0013] The present invention provides a split-type remote control system for wind and oil pumps, which has the following advantages: The main distribution board of the split-type remote control system is equipped with an isolating switch, and several emergency shut-off switches for wind turbines and oil pumps are electrically connected to the isolating switches. Several remote shut-off buttons are provided on the DC distribution board. Each emergency shut-off switch for wind turbines and oil pumps is electrically connected to two remote shut-off buttons. The split design allows for separate control of the shut-off of wind turbines and oil pumps, reducing the shut-off range and ensuring the ship's required power. The redundant circuit design solves the problem of a single circuit failure or short circuit causing all wind turbines and oil pumps to stop working. In the event of a single electrical fault, fire, or single circuit failure or short circuit, only the wind turbines and oil lines on one side of the busbar need to be disconnected, preventing a complete power outage and loss of power to the entire ship, thus ensuring good safety.
