JP2020118152A - Soundproof/waterproof frame for small/medium engine type gas electric generator - Google Patents

Abstract

To provide a device that eliminates a noise damage to the circumference even if a small/medium engine type electric generator is used outdoors, and is used for safely operating a small/medium engine type generator even at the rainy weather.SOLUTION: A small/medium engine type electric generator frame 1 is provided in which the whole outer circumferential part is surrounded by a double structure of a hollow polycarbonate panel 5 and an acoustic material 6 in the inside, and thereby power generation in the outdoor even at the rainy weather and the noise insulation to the circumference in the power generation can be performed. Furthermore, the sound emitted from an intake/exhaust port is reduced by installing an engine-type electric generator in the height of a metal rail 3 of a middle stage, and by installing downwardly an intake port, an intake-air cooling motor fan 7 and an exhaust port 8 below the engine-type electric generator, without directly emitting the sound to the circumference. Furthermore, an air flow rate required by the engine-type electric generator is sufficiently secured by the intake-air cooling fan 7. Also, the engine-type electric generator is cooled to thereby prevent emitting high noise, and the air becoming high temperature by cooling the engine can be exhausted by the exhaust port 8 to thereby enable a long time continuous operation safely.SELECTED DRAWING: Figure 2

Description

The present invention relates to soundproofing and rainproofing measures during use and storage of small and medium-sized engine type generators.

In the past, when a small-to-medium-sized engine type generator was used, noise was loud, which caused annoyance in the neighborhood, and because it could not be used outdoors in rainy weather, some people were killed indoors.

There is no particular reference to small-medium engine generators.

Not particularly.

Therefore, an object of the present invention is to provide a small-to-medium-sized engine type generator base for outdoor installation which can reduce noise generated from the small-to-medium-sized engine generator and can also be provided with a rainproof measure, thereby making it safe and free from noise It is to protect the environment.

Means for solving the problem

In order to solve the above problems, the first aspect of the present invention is to put the noise generated from the small and medium-sized engine type generator in a soundproof case made of a sound absorbing material capable of significantly reducing the noise.

A second aspect of the invention is to provide a double structure of an external structure that can protect the soundproof case from wind and rain.

Further, in the third invention, by installing a movable metal rail for installing the small-medium engine generator in the second middle stage from the bottom, a space between the bottom and the small-medium engine generator is installed. A space can be provided on the bottom and an air intake port and an exhaust port can be attached to the bottom part. As a result, a sufficient amount of intake air and exhaust air can be secured while suppressing sound leakage from the intake and exhaust ports. ..

Further, according to the fourth aspect of the present invention, for the air-cooled engine, by mounting an electric intake cooling fan at the lower intake port, it is possible to realize engine cooling with a reliable intake amount.

Effect of the invention

As described above, according to the first invention and the second invention, the small and medium-sized engine generator can be safely stored, and the noise problem during power generation can be avoided in a case having a high sound absorption coefficient. It can be used even during a power failure due to a typhoon, etc. because it is protected by an external material that can withstand, and the long-term continuous operation is also possible with the intake and exhaust ports of the third and fourth inventions and the intake cooling fan. Becomes

It is a perspective view showing an embodiment of the present invention. It is a perspective perspective view showing an embodiment of the present invention. It is sectional drawing which showed embodiment of this invention.

An embodiment of the present invention is shown in FIGS.
The skeletal material of the small and medium-sized engine generator base is made of robust metal, and the outer periphery exposed to sunlight and wind and rain is also used for the ceiling of gymnasiums and greenhouses, lightweight and fire resistant, heat insulating, weather resistant Of double structure by using a hollow polycarbonate panel with high performance and shock resistance, and by using a sound absorbing material with a high sound absorption coefficient as the internal sound insulating material, and by installing an engine type generator in the middle stage It is possible to provide a space from the outer peripheral portion of the air conditioner, and as a result, it is possible to install an electric intake fan and an exhaust port having a sufficient exhaust volume at the bottom.

Effects of the embodiment

According to this embodiment, the small and medium-sized engine type generator can generate power while being housed in the gantry case of the present invention, and even in a residential area, the noise of the low noise gantry case causes annoying noise in the neighborhood. Since it is possible to operate the power generator in an environment where the wind and rain are strong, it is possible to secure the power supply even in the event of a disaster.

1. Even in areas where it is difficult to secure a power source, it will be possible to generate electricity if the corresponding fuel is secured.
2. It is possible to secure the power supply at the time of power failure without disturbing the neighbors.
3. It is lightweight and fixed outdoors so that it can be installed on the rooftop, for example, to ensure the power supply even in the event of a disaster such as a flood, and it is easy to use in hospitals, shelters, shops, convenience stores and other facilities. The power supply can be secured.

Claims (5)

Generally, the small and medium-sized engine type generator is taken out to generate electricity when necessary, but in the present invention, the small and medium-sized engine type generator is installed on the metal rail 3 in the middle stage. An intake port 7 and an exhaust port 8 that cause sound leakage in order to prevent the noise generated from the engine type generator from leaking to the surroundings as directly as possible are provided on the lower side of the outer peripheral portion which is the lower part of the engine type generator. If necessary, an electric fan is installed in the intake port 7 in order to improve the required intake amount of the engine generator and the cooling performance of the engine generator main body. Since the metal rail 3 is movable, the metal rail 3 can be changed depending on the size of each generator, so that the generator 3 can be easily installed and installed. The outer structure 5 is made of hollow polycarbonate that is lightweight, and has weather resistance, fire resistance, self-extinguishing property, water resistance, chemical resistance, and soundproofing performance.
