Embodiment
Referring to shown in Figure 1: a kind of portable digital variable-frequency power generation unit, it includes left half casing 11, right half casing 13, shell chassis 14, engine 4, generator 5, radiator fan, muffler 8, inverter 1, it is characterized in that: the right output at engine 4 is connected with generator 5 and right radiator fan 6, is connected with left radiator fan 3 and dish 2 is drawn in startup at the left output of engine 4; Described muffler 8 is arranged on the top of generator 5; The bottom of half casing 11, right half casing 13 is provided with shell chassis 14 on a left side, and described engine 4, generator 5, inverter 1 are arranged on the shell chassis 14.
Outer setting at described engine has engine wind scooper 10, in the outer setting of muffler muffler guard shield 9 is arranged, and in the outer setting of generator generator guard shield 7 is arranged.
This portable digital variable-frequency power generation unit is to have carried out a large amount of improvement on the basis of existing portable digital variable-frequency power generation unit structure, and the structure of unit is optimized more, and unit is operated under the good environment.
Concrete improvement is aspect following:
One, improved the cooling system of unit, unit is operated under the lower temperature environment.
1, increase radiator fan:
This portable digital variable-frequency power generation unit adopts two radiator fans, draws in the startup of existing portable digital variable-frequency power generation unit structure on the basis of the radiator fan 3 that coils side, has increased a radiator fan 6 at the generating pusher side again.Increase the speed and the flow of the air flows of casing inside, unit is better cooled off.Having changed in the existing structure provides the suction of cold wind little by radiator fan 3, causes air flows slow, the drawback that air quantity is little.
1) starting the radiator fan 3 that draws the dish side discharges the heat that engine 4 produces separately.
By the suction of radiator fan 3, cold wind enters in the casing from the ventilating opening 12 on panel and the left and right sides shell, enters the wind scooper 10 of engine by inverter 1, the cylinder head part that cooling is started, by the surface of muffler 8, the cooling muffler is discharged the casing outside then then.
2) radiator fan 6 of generating pusher side is responsible for the heat that generator 5 produces is got rid of.
By the suction of radiator fan 6, the cold wind that part enters in the casing from panel and left and right sides ventilation for enclosures mouth 12 is by the cavity of casing inside, behind the body of cooled engine, enter generator guard shield 7, cooled electric generator is discharged the casing outside by radiator fan 6 then.
2, the position of will mainly dispelling the heat utilizes guard shield to isolate:
This unit has two big heating positions, be respectively engine and generator two parts, we utilize engine wind scooper, muffler guard shield and generator guard shield that engine, muffler and generator are isolated, the heat that two parts are produced is discharged casing respectively, the air-flow that both produce flows separately, does not get muddled.Fully reduce the temperature in the casing.
Two, changed the assembling mode of casing.
The shell of this portable digital variable-frequency power generation unit adopts left half casing 11, right half casing 13 and shell chassis 14 3 parts to form, engine 4 and generator 5 combinations are passed through on the mounting bracket 402 of mounting screw 401 with its installation, and mounting bracket 402 usefulness screws 403 are fixed on the shell chassis 14.
So at first stationary engine and generating set are incorporated on the shell chassis, and other parts are installed, and at last a left side half casing, right half casing are fixed on the shell chassis and get final product.Be easy to install and maintain.
Three, changed the mounting means of inverter.
In view of the inverter of existing structure is to fix by the outstanding mounting points of a left side half casing, right half casing, because the weight of inverter is all born by mounting points, in transportation and use, cause mounting points and shell to be torn easily, inverter of the present invention directly is installed on the shell chassis 14 by inverter mounting bracket 404, like this weight of inverter 1 is all transferred on the shell chassis 14, inverter solid and reliable can not damage shell.
Four, changed the structural arrangement form of casing inside.
This portable digital variable-frequency power generation unit improves the layout type of existing structure, and the existing structure employing is installed to engine start with generator and draws the dish side, and muffler is arranged in the outlet side of engine.
This portable digital variable-frequency power generation unit is arranged into generator 5 outlet side of engine 4, muffler 8 is arranged in the top of generator 5, and both are separated with muffler guard shield 9 and generator guard shield 7, and be bonded with the asbestos insulation material in the inboard of muffler guard shield, temperature rise impacts to generator to prevent the heat of engine, influence the operational environment and the state of generator, give full play to the usefulness of generator.
Arrange so simultaneously, make the stressed distribution equilibrium of bent axle of engine 4, improve the condition of work of bent axle, reduce the abrasion condition of engine, prolong the life-span of engine.
