Description

TECHNICAL FIELD

[0001] The present application relates to a safety system for an inlet and outlet valve of a bilge fire pump, and more particularly, to a safety system for an inlet and outlet valve of a bilge fire pump and a control method thereof. BACKGROUND

[0002] Currently, in view of economy, a bilge fire pump is usually used in the design of a ship system, that is, the same pump is used as a fire pump and a bilge pump. In a fire mode, water is pumped from a seawater system to fire hydrants for fire use. In a bilge mode, water is pumped from a water inlet cabin to the outside of a ship for ship protection.

[0003] A conventional design is to provide a manual isolation valve. When a relevant mode is operated, the manual valve is opened or closed to control the water flow direction of a pipeline to meet the fire or bilge operation.

[0004] A problem of this design is that if a certain area is on fire, but the valve pipeline is not switched to the fire operation mode by mistake, and the pipeline valve is checked again in a critical situation, the fire extinguishing opportunity is directly delayed, causing irreparable loss. If a large amount of water enters a certain area, and the relevant valve is opened to the fire passage, the water entering accident will be more serious, and even an uncontrollable risk of whole-cabin water entering will be caused. SUMMARY

[0035] The seawater total pipe 12 is provided with a fire pipeline inlet total valve 2.

[0036] The bilge total pipe 13 is provided with a bilge pipeline inlet total valve 3.

[0037] The fire hydrant pipe 14 is provided with a fire pipe outlet master valve 4.

[0038] The bilge pipe 15 is provided with a bilge pipe outlet master valve 5.

[0039] The safety system further comprises a pump control box 6 and a ship management system 7, the pump control box 6 is used to control the mode switching of the bilge fire master pump 1, and the ship management system 7 is used to control the corresponding opening and closing of the fire pipe inlet master valve 2, the bilge pipe inlet master valve 3, the fire pipe outlet master valve 4 and the bilge pipe outlet master valve 5.

[0040] The fire pipe inlet master valve 2, the bilge pipe inlet master valve 3, the fire pipe outlet master valve 4 and the bilge pipe outlet master valve 5 are all remote control valves.

[0041] The pump control box 6 and the ship management system 7 are in communication.

[0042] The inlet of the bilge fire master pump 1 is connected to the fire inlet master valve 2 and the bilge inlet master valve 3, and the outlet is connected to the fire outlet master valve 4 and the bilge outlet master valve 5. In the automatic mode, when the pump group mode switching is performed through the pump control box 6, the corresponding valves are automatically opened or closed through the ship management system 7.

[0043] In combination with Figure 2 the accompanying drawings, the present application further provides a control method for the safety system of the bilge fire master pump inlet and outlet valves based on the present application;

[0044] The pump control box 6 is used to control the switching of the pump group mode operation of the bilge fire master pump 1, and the control signal is transmitted to the ship management system 7, so that the ship management system 7 controls the corresponding opening and closing of the fire pipe inlet master valve 2, the bilge pipe inlet master valve 3, the fire pipe outlet master valve 4 and the bilge pipe outlet master valve 5, so as to realize the fire mode operation or the bilge mode operation of the bilge fire master pump 1.

[0045] The switching of the fire mode of the bilge fire master pump 1 comprises the following steps:

[0046] S1, the pump control box 6 controls the switching of the bilge fire master pump 1 from the bilge mode to the fire mode;

[0047] S2, the ship management system 7 receives the mode switching signal sent by the pump control box 6;

[0048] S3, the ship management system 7 controls the corresponding opening of the fire pipe inlet master valve 2 and the fire pipe outlet master valve 4, and the corresponding closing of the bilge pipe inlet master valve 3 and the bilge pipe outlet master valve 5, that is, the fire hydrant pipe 14 is automatically connected and the bilge pipe 15 is automatically closed in the conventional fire mode.

[0049] The switching of the bilge mode of the bilge fire pump 1 comprises the following steps:

[0050] S1, the pump control box 6 controls the bilge fire pump 1 to switch from the fire mode to the bilge mode;

[0051] S2, the ship management system 7 receives the mode switching signal sent by the pump control box 6;

[0052] S3, the ship management system 7 controls the corresponding opening of the bilge pipe inlet total valve 3 and the bilge pipe outlet total valve 5, and the corresponding closing of the fire pipe inlet total valve 2 and the fire pipe outlet total valve 4.

[0053] In the fire mode or the bilge mode, if the fire pipe inlet total valve 2, the bilge pipe inlet total valve 3, the fire pipe outlet total valve 4 and / or the bilge pipe outlet total valve 5 do not receive the control signal of the ship management system 7, the ship management system 7 sends an alarm signal.

[0054] Since the probability of using the bilge mode in the operation of the ship is low, the bilge fire pump 1 is usually in the fire mode, so after occasionally using the bilge mode, it must be switched back to the fire mode to be ready for safety testing or actual fire at any time. Thus, when the fire fighting operation is performed, there is a standard required water flow at any fire hydrant, so as not to delay the fire extinguishing opportunity due to no water available.

[0055] However, if the actual cabin water needs to use the bilge mode, it must be switched from the fire mode to the bilge mode for the bilge water removal operation.

[0056] All the settings in the present technology are for fire fighting and bilge safety. Since the fire is inevitable due to the fuel equipment on the ship, and the ship water entry is also an accident that may occur, the present technology is designed at the operation source, and plays a very key role in the safety of the ship.

[0057] Those skilled in the art in the technical field should realize that the above embodiments are only used to illustrate the present application, and are not used as a limitation on the present application. As long as the changes and modifications of the above described embodiments are within the scope of the spirit of the present application, they will fall within the scope of the claims of the present application.
