Description

Technical Field

[0001] The present invention relates to the technical field of ship fire-fighting devices, and particularly to a sprinkler system and a ship. Background Art

[0002] The function of the sprinkler system is to use the medium water to spray the burning object through the nozzles on the pipeline to extinguish the fire when a fire occurs. It has the advantages of low price and high fire extinguishing efficiency.

[0003] The sprinkler system is widely arranged on ships. The sprinkler system connects the sprinkler pump and the sprinkler head through the sprinkler pipeline, transports the fire extinguishing medium, such as water, to the sprinkler head, and acts on the sprinkler head through the pressure provided by the sprinkler pump. A water mist can be formed around the sprinkler head to meet the fire extinguishing requirements. In the prior art, the sprinkler system arranged on ships generally uses seawater as the fire extinguishing medium. Since seawater has a high salt content and is corrosive, it is easy to cause pipeline corrosion when it exists in the sprinkler pipeline for a long time. Therefore, it is generally necessary to flush the sprinkler pipeline by connecting fresh water. However, due to the large range of the sprinkler pipeline of the sprinkler system and the large number of sprinkler nozzles, and the fresh water pump and the water supply of the fresh water pump are small, it is impossible to meet the flushing work of the entire sprinkler pipeline.

[0004] Therefore, there is an urgent need for a sprinkler system and a ship to solve the above problems. Summary of the Invention

[0036] Figure 1 A schematic diagram showing the sprinkler system provided by an embodiment of the present invention. Refer to Figure 1 , the sprinkler system provided in this embodiment includes a sprinkler pipeline 100 and a flushing water source 200. The sprinkler pipeline 100 is arranged in the cabin area, and the sprinkler pipelines 100 in multiple cabin areas are independent of each other. The sprinkler pipeline 100 is configured to deliver the fire extinguishing medium to the corresponding cabin area.

[0037] Specifically, the spray pipeline 100 is divided into zones according to different cabin areas to form a spray pipe network, and the spray pipelines 100 in multiple cabin areas are independent of each other. The flushing water source 200 is selectively connected to the spray pipelines 100 in multiple cabin areas, and the flushing water source 200 is configured to supply flushing water to the spray pipelines 100 connected thereto.

[0038] More specifically, the spray pipeline 100 in the same cabin area is divided into multiple independent branch pipelines 110, and the flushing water source 200 is selectively connected to the multiple branch pipelines 110. In this embodiment, the cabin is divided into two areas, namely the first cabin area and the second cabin area, as Figure 1 shown. The spray pipeline 100 in the first cabin area and the spray pipeline 100 in the second cabin area are respectively connected to the flushing water source 200, and the water in the flushing water source 200 can be supplied only to the spray pipeline 100 in the first cabin area for pipeline flushing, or only to the spray pipeline 100 in the second cabin area for pipeline flushing. Through the above settings, the flushing water can be concentrated in the spray pipeline 100 in one cabin area, improving the effect of pipeline flushing. In other embodiments, the cabin can also be divided into more than two cabin areas, and the number of cabin divisions in this embodiment is not limited.

[0039] Even more specifically, a branch control valve 111 is provided between each branch pipeline 110 and the flushing water source 200, and the branch control valve 111 is configured to control the on-off between the flushing water source 200 and the branch pipeline 110. The branch control valve 111 can select any valve in the prior art that can realize pipeline on-off control, and its structure and principle are not described in detail in this embodiment.

[0040] This embodiment describes by taking the layout of the spray pipeline 100 in the first cabin area as an example. Figure 2 The schematic diagram of the spray pipeline in the first cabin area provided by the embodiment of the present invention is shown. Refer to Figure 2 , the spray pipeline 100 in the first cabin area is divided into four branch pipelines 110, namely the independent first branch pipeline, second branch pipeline, third branch pipeline and fourth branch pipeline. A branch control valve 111 is provided between each of the above branch pipelines 110 and the flushing water source 200. Through different branch control valves 111, the on-off control between each of the above branch pipelines 110 and the flushing water source 200 can be realized. That is to say, after the flushing water enters the spray pipeline 100 in the same cabin, it can be further divided into more detailed zones, concentrating the flushing water, and sequentially flushing the multiple branch pipelines 110 to ensure the flushing effect and improve the flushing efficiency.

[0041] Continue to refer to Figure 1, the sprinkler system further includes a liquid tank 400, which is arranged upstream of the sprinkler pipe network and is configured to supply a fire extinguishing medium to the sprinkler pipe network, and the sprinkler pipe network can distribute the fire extinguishing medium to multiple cabin areas. In this embodiment, the fire extinguishing medium is seawater.

[0042] Specifically, the sprinkler system further includes a plurality of sprinkler heads 300. A plurality of sprinkler heads 300 are arranged in the cabin area, and the sprinkler heads 300 are arranged at the top of the cabin area. Each branch pipe 110 is connected to a plurality of sprinkler heads 300, and the sprinkler heads 300 are configured to spray the fire extinguishing medium into the cabin area.

[0043] More specifically, the sprinkler system further includes a sprinkler power supply mechanism 500. The sprinkler power supply mechanism 500 is arranged between the liquid tank 400 and the sprinkler pipe network, and the sprinkler power supply mechanism 500 is selectively connected to the sprinkler pipes 100 in multiple cabin areas. The sprinkler power supply mechanism 500 is configured to transport seawater to the sprinkler pipes 100.

[0044] Even more specifically, the sprinkler power supply mechanism 500 includes a sprinkler pump 510 and a first control valve 520. The sprinkler pump 510 is connected to the liquid tank 400. The sprinkler pump 510 can pump the seawater in the liquid tank 400 to the sprinkler pipes 100, and the pressure provided by the sprinkler pump 510 acts on the sprinkler heads 300 to form a water mist around the sprinkler heads 300. A number of sprinkler heads 300 are arranged in each cabin area, and each sprinkler head 300 covers a certain area to meet the fire extinguishing requirements. The first control valve 520 is arranged between the sprinkler pump 510 and the sprinkler pipe network and is configured to control the on-off of the sprinkler pump 510 and the sprinkler pipe network.

[0045] Even more specifically, the sprinkler power supply mechanism 500 further includes a second control valve 530. The second control valve 530 is arranged between the sprinkler pump 510 and the liquid tank 400 and is configured to control the on-off of the sprinkler pump 510 and the liquid tank 400. Both the above-mentioned second control valve 530 and the first control valve 520 can select pipeline valves in the prior art, and their structures and principles will not be elaborated in this embodiment.

[0046] Preferably, in this embodiment, there are a plurality of sprinkler power supply mechanisms 500. The plurality of sprinkler power supply mechanisms 500 are connected in parallel with each other and are respectively connected to the sprinkler pipe network. The plurality of sprinkler power supply mechanisms 500 that can work independently can improve the reliability of the sprinkler system.

[0047] Optionally, a liquid discharge testing mechanism 600 is provided on the connecting pipeline between the spray power supply mechanism 500 and the spray pipe network. When the liquid discharge testing mechanism 600 is opened, the drainage test of the spray power supply mechanism 500 can be carried out, so as to check whether the spray power supply mechanism 500 can work normally.

[0048] Preferably, the spray system further includes a purging air source 700, which is selectively connected to the spray pipelines 100 in multiple cabin areas, and the purging air source 700 is configured to purge the spray pipelines 100. When the passage between the purging air source 700 and the spray pipeline 100 and the passage between the spray power supply mechanism 500 and the spray pipeline 100 are opened simultaneously, the purging air source 700 increases the pressure in the spray pipeline 100, facilitating the flushing water to rush to the end of the spray pipeline 100 and being able to flush the spray heads 300, improving the efficiency and effect of pipeline flushing.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention.
