Description

A kind of vibration and noise reducing device of gasoline engine generator
Technical field
The present invention relates to the vibration and noise reducing device of a kind of gasoline engine generator, particularly relate to the vibration and noise reducing device of a kind of gasoline engine generator, Belong to vibration damping de-noising field.
Background technology
Gasoline engine generator because of its compact conformation, start the features such as simple, electric current output is stable, be widely used in movie theatre, hospital, The place such as factory, field, as emergent stand-by power supply.But during using gasoline engine generator, there is also following asking Topic: one is that noise is big, when this is due to gasoline engine drive generator operation, is produced by piston, the motion of gear quasi-periodic Excitation applies the shell to gasoline engine generator, causes the forced vibration of housing, thus produces the strongest radiated noise;Two is vibration Greatly, the total quality of gasoline engine electromotor is little, but gasoline engine power is relatively big, piston, the motion of gear quasi-periodic produce Vibration is very big, often makes gasoline engine generator work after a period of time and leaves original position;Three be gasoline engine generator be placed on ground use time, Can feel that noise is bigger, this is because ground is as the absolute bounds in aeroacoustics problem, the radiation impedance of sound source can be increased, The radiation acoustic energy making sound source becomes original 2 times;Four is that the radiated noise that gasoline combustion, cylinder moving etc. produce easily passes through Aiutage propagates from, and owing to the aiutage of gasoline engine generator is the shortest, decline noise reduced ability, and this is also makes an uproar the strongest Sound source.Therefore, gasoline engine generator to people provide huge easily time, there is also problems.
Chinese patent " a kind of new type gasoline generating set " (patent No. 201220676510), is carried out the outward appearance of gasoline engine generator Improving, this patent has only carried out vibration and noise reducing to the subregion of gasoline engine generator, fails to consider that the vibration of gasoline engine generator is special Property, fail to carry out on the whole the vibration and noise reducing measure of gasoline engine generator.
Chinese patent " triplex water-cooling gasoline engine generator " (patent No. 200920294462), has carried out water to gasoline engine generator Cold heat radiation, and the method for operation of gasoline engine generator is improved, but the radiated noise of gasoline engine is not carried out noise reduction measure.
Summary of the invention
The invention aims to can solve the problem that the problems referred to above that gasoline engine generator in use exists provide a kind of gasoline The vibration and noise reducing device of electromotor.
The object of the present invention is achieved like this: includes big case, little case, gasoline engine generator, L-type exhaustor and high temperature steam pipe, Being provided with location steel column on described big case inner bottom, little bottom portion is provided with positioning steel tube, and positioning steel tube coordinates, greatly with location steel column Being filled with water in the space that case becomes with little box-shaped, big case inner bottom is additionally provided with discharging valve, little case upper end is provided with cover plate, on cover plate Being provided with two holes, the hole of left end is sealed and installed with observation window, and right-hand member hole is sealed and installed with suction plate, and suction plate upper end is provided with four The individual mouth of pipe, vertically-mounted on each mouth of pipe have welded pipe, and gasoline engine generator is arranged on little case inner bottom by supporting seat, and gasoline is sent out Motor row inflator is connected with one end of high temperature steam pipe, and the other end of high temperature steam pipe is connected with the horizontal segment of L-type exhaustor, and The horizontal segment of L-type exhaustor passes the sidewall of little case and is positioned in the space that little case becomes with big box-shaped, the vertical section of L-type exhaustor End be positioned on the water surface, the horizontal segment of L-type exhaustor and vertical section are respectively arranged with left catch and right catch.
Present invention additionally comprises so some architectural features:
1. described in, left catch is identical with right baffle structure, is all the semicircle steel disc identical with exhaustor internal diameter, and thickness and aerofluxus The thickness of pipe is equal.
2. the bottom symmetrical of big case is provided with four universal wheels.
3. the material of observation window described in is lucite.
Compared with prior art, the invention has the beneficial effects as follows: the buoyancy that the present invention utilizes the water between little case and big case to produce with Little case, the gravity of gasoline engine generator are balanced, so that gasoline engine generator is in free vibration state, owing to aqueous medium can only Bear pressure, and pulling force can not be born, namely the vibrational system of little case, gasoline engine generator and water composition is non-linear vibrating system, Thus the periodicity forced vibration of gasoline engine generator of can decaying significantly;Utilize little case and the closing space of cover plate composition, by gasoline Electromotor carries out airtight, weakens the ability of gasoline engine generator outside space radiation noise;Copper pipe in suction plate uses sectional area Continually varying index shape horn constructs, in this, as the air inlet of gasoline engine generator, owing to the sectional area on horn top is little, sound Impedance is big, and the sectional area of bottom is relatively big, and acoustic impedance is less, and the sound wave in little case is by the drastically change of copper pipe acoustic impedance so that big The acoustic reflection of part returns among little case, and the acoustic energy radiateing through copper pipe is the least;Use and exhaustor is placed on aqueous medium In, cool the temperature of exhaustor, utilize the sectional area sudden change that left catch and right catch are formed, the sound wave in exhaustor is formed Reflection, reduces the noise radianting capacity by exhaustor further;Owing to little case uses corrosion resistant plate to make, heat conductivility is good Good, and be aqueous medium outside little case, the heat that can in use produce gasoline engine generator is lowered the temperature;The four of big case Individual universal wheel is as supporting construction so that little case, gasoline engine generator are away from ground, and this also weakens the noise spoke of gasoline engine generator Penetrate ability;The present invention uses aqueous medium as damping medium, when not in use, can be bled off by water, has simple to operate, use The features such as convenience.
