Problems solved by technology

[0004] The purpose of the present invention is to overcome the defect that when the existing lifeboat capsizes, because the lubricating oil of the lifeboat diesel engine is completely lost, the oil suction port of the oil pump has no oil to suck, which seriously affects the diesel engine lubrication system and the breathing system cannot exhaust; to provide a simple structure 1. A reliable device, which can ensure that the lubrication system and breathing system of the lifeboat diesel engine can work normally when it is inverted

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0017] like figure 1 , figure 2 and image 3 As shown, a one-way sealing mechanism 2 is provided on the top of the oil pan 1 of the present invention. The one-way sealing mechanism 2 in this embodiment consists of an oil pan partition 21, an oil pump suction port 22, a gasket 23, and three The oil sump check valve 24 constitutes. The oil pan 1 is arranged below the crankcase 3, and a gasket 23 is provided between the bottom of the crankcase 3 and the oil pan partition 21 to seal the oil pan 1; the crankcase 3, the oil pan partition 21 It is fixedly connected with the top of the oil pan 1 by screws 25 .

[0018] The oil suction port 22 of the oil pump is fixedly arranged on the oil pan partition 21, and three oil pan check valves 24 are installed under the oil pan partition 21. The check valve is supported by a valve housing 242, a valve ball 241 and The...

Abstract

The invention discloses a non-shutdown device for the inversion of a lifeboat diesel engine, which comprises a lubrication system and a respiratory system, wherein the lubrication system comprises an oil suction port of an oil pump and an oil tray arranged at the bottom of a crankcase; and the respiratory system comprises a main respirator holder arranged on a cylinder cover and a main respiration channel which passes through a machine body of the diesel engine. The top of the oil tray is provided with a unidirectional sealing mechanism, a main respirator check valve is arranged in the main respirator holder, a secondary respiration channel is arranged in the machine body of the diesel engine, and an advancer cover is provided with a secondary respirator check valve. The device has a simple structure and low cost, can meet the requirement stipulated in the SOLAS convention, and solve the lubrication problem of a diesel engine system and the air exhaust problem inside the crankcase when the lifeboat diesel engine is in an inverted state.

Description

technical field [0001] The invention relates to a safety protection device for a lifeboat diesel engine, in particular to a device for keeping the lifeboat diesel engine working normally without stopping when the diesel engine of a fully enclosed lifeboat is thrown or capsized due to special sea conditions. It belongs to ship technology field. Background technique [0002] In order to ensure that the lifeboats can be fully utilized in the event of a marine accident, the International Convention on the Safety of Life at Sea (SOLAS Convention) formulated by the International Maritime Organization stipulates: "The engine and its devices should be able to operate at any position during the capsizing process, and in The lifeboat is capable of continuing to operate after being turned back upright...the fuel and lubricating oil system should be designed to prevent the loss of fuel and more than 250ml of lubricating oil from the engine during capsizing." [0003] In order to meet t...
