The oil suction pipe comprises an upper oil suction pipe and a lower oil suction pipe, wherein the lower end of the oil suction pipe is fixedly connected with the oil suction coarse strainer; and the lower end of the upper oil suction pipe and the upper end of the lower oil suction pipe are bent 90 degrees respectively. The rotating sleeve mechanism comprises an inner sleeve and an outer sleeve, wherein the inner sleeve is rotatably sleeved in the outer sleeve; one end of the inner sleeve is fixedly connected with the upper end of the lower oil suction pipe; and one end of the outer sleeve is fixedly connected with the lower end of the upper oil suction pipe. When a diesel engine is turned over and inverted, the oil suction coarse strainer and the lower oil suction pipe rotate around the axis of the rotating sleeve mechanism, so that the oil suction coarse strainer keeps downwards, the oil suction position is always positioned at the bottom of the engine oil in an oil pan, the utilization rate of the engine oil is improved, the volume of the oil pan can be reduced simultaneously, and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to a kind of lubrication system of small diesel engine, especially a kind of totally-enclosed and can 360 the salvage boat diesel engine oil pump Oil sucking device of degree upset, belong to technical field of ships.
Background technique
Conventional diesel engine, as power source, is all worked, as the automotive Diesel engine of transportation use, the diesel generating set that engineering is used etc. under positive configuration state; Its oil pump oil suction position all in the oil sump of diesel engine bottom, and immobilizes.As the totally enclosed lifeboat of boats and ships survival equipment, due to its special job specification, in leaving process, be subject to the invasion of stormy waves, salvage boat need to possess and be inverted in short-term ability to work with diesel engine.Application number is that the technological scheme that the Chinese invention patent application prospectus of 200810154941.5 " non-stopping device for lifeboat diesel engine while inversion " provides has solved salvage boat diesel engine under inversion state, the system lubrication problem of diesel engine and the exhausting problem of crankcase inside.Lubrication problem when solving diesel engine inversion work, this technological scheme has been installed a dividing plate with several one-way valves between oil sump and crankcase, when diesel engine is just being put work, under the effect of gravity, machine oil flows in oil sump from crankcase, realize oil circulation and use, oil pump oil suction is immersed in machine oil all the time; During diesel engine inversion work, oil sump is by unidirectional valve closure, and the machine oil in it can not flow into crankcase naturally, meanwhile, also must, in the situation that machine oil does not have reflux cycle, guarantee that oil pump oil suction is immersed in machine oil all the time.Adopt increase oil sump volume at present to increase machine oil deposit, rationally determine oil pump oil suction position, thereby assurance diesel engine is just being put and is being inverted under two states and can both normally work simultaneously.But, because inlet port position is fixedly installed, to meet simultaneously and just put and be inverted two kinds of working staties, must cause a big chunk machine oil in oil sump not to be fully utilized, thereby make the wasting of resources, also cause diesel engine boundary dimension and weight to increase simultaneously.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, easily manufactured diesel engine oil pump Oil sucking device, at diesel engine, just put, be inverted under two kinds of working staties, oil pump oil suction is followed rotation automatically along with diesel engine upset, inlet port position remains at the bottom of machine oil, can make full use of the machine oil of oil sump, assurance diesel engine is normally worked.
The present invention is achieved by the following technical programs:
A diesel engine oil pump oil suction device, comprises inlet port strainer, fuel sucking pipe, turnbarrel mechanism, and described fuel sucking pipe comprises fuel sucking pipe, lower fuel sucking pipe, and termination, described fuel sucking pipe lower end is fixedly connected with inlet port strainer; Described upper fuel sucking pipe lower end, lower fuel sucking pipe upper end be 90-degree bent respectively, described turnbarrel mechanism comprises inner sleeve, outer sleeve, described inner sleeve is sleeved in outer sleeve rotationally, described inner sleeve one end is fixedly connected with lower fuel sucking pipe upper end, and described outer sleeve one end is fixedly connected with upper fuel sucking pipe lower end.
Object of the present invention can also further realize by following technical measures.
Aforesaid diesel engine oil pump oil suction device, wherein said outer sleeve is sleeved on inner sleeve rotationally, and described outer sleeve one end is fixedly connected with lower fuel sucking pipe upper end, and described inner sleeve one end is fixedly connected with upper fuel sucking pipe lower end.
Aforesaid diesel engine oil pump oil suction device, the face that relatively rotates between wherein said inner sleeve and outer sleeve is provided with seal ring.
Aforesaid diesel engine oil pump oil suction device, wherein said turnbarrel mechanism is provided with axial limiting screw, and described axial limiting screw is radially threaded with outer sleeve, and axial limiting screw head is flexibly connected with inner sleeve.
Aforesaid diesel engine oil pump oil suction device, is provided with circlip in wherein said turnbarrel mechanism, and described circlip is arranged in outer sleeve endoporus, is positioned at the front side of inner sleeve one end.
The present invention is simple in structure, and reliability is high.When diesel engine flips upside down, under the deflecting torque effect that inlet port strainer of the present invention and lower fuel sucking pipe produce turnbarrel mechanism axis at gravity, axis around turnbarrel mechanism rotates, inlet port strainer is kept down, inlet port position is positioned at the machine oil bottom of oil sump all the time, improved the utilization ratio of oil sump inner engine oil, can reduce oil sump volume, reduced manufacture cost simultaneously.
Advantage and disadvantage of the present invention, the non-limitative illustration by preferred embodiment below is for illustration and explanation, and these embodiments, only provide as an example with reference to accompanying drawing.
