Description

Technical Field

[0001] The utility model relates to a lifeboat, in particular to a fire-resistant lifeboat. Background Art

[0002] At present, fire-resistant lifeboats are equipped on offshore drilling platforms or offshore oil and gas production platforms. When a fire breaks out on the platform, the personnel on the platform take the fire-resistant lifeboat to escape. When the fire-resistant lifeboat is lowered from the platform to the sea surface, the fire-resistant lifeboat sprays water mist around the lifeboat so that the lifeboat will not be burned by the fire. The fire-resistant lifeboat mainly includes a hull, an engine, a propeller shaft, a propeller, a water pump, a water intake pipe, a heat exchanger and a spraying system; the engine is arranged at the rear end of the hull, one end of the propeller shaft is connected with the engine, and the other end of the propeller shaft extends out of the rear end of the hull and is connected with the propeller; the water pump is connected with the engine, one end of the heat exchanger is connected with the engine, and the other end of the heat exchanger is connected with the water pump; the spraying system is communicated with the water pump, and the water intake pipe is arranged at the bottom of the hull and is connected with the water pump; when the fire-resistant lifeboat is lowered from the platform to the sea surface, the engine drives the propeller through the propeller shaft to push the hull, and at the same time the engine drives the water pump to work. The water pump sucks seawater from the sea through the water intake pipe and transports it to the spraying system. The spraying system sprays water mist around the lifeboat, and the heat exchanger cools the engine through the water transported by the water pump; since the fire-resistant lifeboat is usually suspended on the drilling platform or offshore oil and gas production platform, it is necessary to regularly check whether the spraying system of the fire-resistant lifeboat is effective. It is necessary to lower the fire-resistant lifeboat into the sea for test inspection, and then lift it back to the platform after the test inspection; this test inspection is very time-consuming and laborious. Summary of the Invention

[0003] Aiming at the above disadvantages, the purpose of the utility model is to provide a fire-resistant lifeboat that can save time and effort in directly testing the effectiveness of the spraying system on the platform.

[0004] The technical content of the utility model is a fire-resistant lifeboat, which includes a hull, an engine, a propeller shaft, a propeller, a water pump, a water intake pipe, a heat exchanger and a spraying system; the engine is arranged at the rear end of the hull, one end of the propeller shaft is connected with the engine, and the other end of the propeller shaft extends out of the rear end of the hull and is connected with the propeller; the water pump is connected with the engine, one end of the heat exchanger is connected with the engine, and the other end of the heat exchanger is connected with the water pump; the spraying system is communicated with the water pump, and the water intake pipe is arranged at the bottom of the hull and is connected with the water pump; its characteristics are that it further includes a water delivery pipe, a water storage bag and a cooling sleeve; one end of the water delivery pipe is connected with the water storage bag, and the other end of the water delivery pipe is connected with the water pump; a cooling sleeve is sleeved outside the propeller shaft, and the cooling sleeve is communicated with the heat exchanger.

[0005] The advantages of the present utility model compared with the prior art are as follows: The present utility model can directly conduct the effectiveness test and inspection of the sprinkler system of the fire-resistant lifeboat on a drilling platform or an offshore oil and gas production platform, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 It is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0007] As Figure 1 shown, a fire-resistant lifeboat includes a boat body 1, an engine 2, a propeller shaft 3, a propeller 4, a water pump 5, a water intake pipe 6, a heat exchanger 7, and a sprinkler system 8; the engine 2 is arranged at the rear end of the boat body 1, one end of the propeller shaft 3 is connected to the engine 2, and the other end of the propeller shaft 3 extends out of the rear end of the boat body and is connected to the propeller 4; the water pump 5 is connected to the engine 2, one end of the heat exchanger 7 is connected to the engine 2, and the other end of the heat exchanger 7 is connected to the water pump 5; the sprinkler system 8 is communicated with the water pump 5, and the water intake pipe 6 is arranged at the bottom of the boat body 1 and is connected to the water pump 5; its characteristics further include a water delivery pipe 9, a water storage bag 10, and a cooling sleeve 11; one end of the water delivery pipe 9 is connected to the water storage bag 10, and the other end of the water delivery pipe 9 is connected to the water pump 5; a cooling sleeve 11 is sleeved outside the propeller shaft 3, and the cooling sleeve 11 is communicated with the heat exchanger 7.

[0008] The working principle of the present utility model is that when conducting the test and inspection of the sprinkler system on a drilling platform or an offshore oil and gas production platform, first fill the water storage bag 10 with water, and then start the engine 2. The engine 2 drives the propeller shaft 3 to rotate idly; the engine 2 drives the water pump 5 to work. At this time, the heat exchanger 7 cools the engine 2 and the propeller shaft 3 through the water conveyed by the water pump, and at the same time, the water in the water storage bag 10 is conveyed to the sprinkler system 8 through the water pump 5 from the water delivery pipe 9 for spraying, thereby conducting the effectiveness test and inspection of the sprinkler system.
