Does not occur, the pressure in the package does not fluctuate, and it is possible to finely adjust the fuel gas pressure by the governor for the gas engine.
[0012]
In this case, by making the opening of the switch operation door small as long as the operation switch on the control panel can be operated, the opening and the switch operation door can be made small, and the inflow and outflow of air due to opening and closing of the switch operation door can be reduced. The packing configuration can be simplified.
[0013]
Further, since the shielding member is formed of a solid packing, leakage of noise in the package can be reduced.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described. FIG. 1 is a front view showing the entire packaged power generation device according to the present invention, FIG. 2A is an enlarged front view showing a main part of FIG. 1, and FIG. FIG. 3 is a side sectional view taken along line A. 1 and 2, a gas engine 1 and a generator 2 which are directly connected to each other via a vibration isolating mat 4 are mounted on a base 3, and a control panel 7 having an operation switch 8 on a side thereof is directly connected to the gas engine 1 and the generator 2. It is placed on the base 3.
[0015]
These devices are hermetically covered by a package 9 having a soundproof wall structure in which a sound deadening material is attached to an inner wall, and a ventilation fan 10 cools the gas engine 1 and the generator 2 inside the package 9 through an intake port 9a. The air is ventilated through the exhaust port 9b as shown by the arrow, and the internal pressure is kept constant. A silencing duct (not shown) is connected to the intake port 9a and the exhaust port 9b of the package 9.
[0016]
The gas engine 1 is connected to a fuel supply source outside the package 9 via a gas fuel pipe 4 via a governor 6, and detects the pressure inside the package 9 by a pressure sensor (not shown) and responds to the pressure inside the package 9. The governor 4 finely adjusts the fuel gas pressure. The gas engine 1 is configured to take in air from outside the package 9 through an intake pipe (not shown) and discharge combustion gas to the outside of the package 9 through an exhaust pipe 11.
[0017]
The package 9 is provided with an opening of substantially the same size as the control panel 7 at a position facing the control panel 7, and a control panel maintenance door 13 for closing the opening is provided to be openable and closable. The maintenance of the control panel 7 can be performed by opening the control panel maintenance door 13.
