Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a power station building for an engine generator of an uninterruptible power supply system used in a wireless relay station or the like.

Conventionally, uninterruptible power supply systems used in wireless relay stations, etc., supply AC power using engine generators fueled by gasoline or light oil, etc., and are used for emergency purposes during commercial power outages. It is used as a regular power source in remote mountain areas where electricity is not available.

However, engine generators are relatively heavy and require a strong base for installation, piping for engine generators is easily affected by the external environment, and various related equipment must be fixed. For these reasons, a power station building or power room-type house 1 as shown in FIG. 1 is usually constructed.

In constructing this house 1, not only the construction of the mounting floor 2 but also the installation of the engine generator 3 and related equipment 4, as well as wiring and piping work, must be done at the installation site.

Therefore, when constructing an uninterruptible power supply plant including the engine generator in a remote location, each device is individually packed and transported to the construction site, unpacked at the construction site, and then installed by on-site construction. , wiring, piping, and testing must be carried out, resulting in damage to each device during transportation, increased packaging costs, difficulty in on-site construction in adverse environments, and prolonged construction period, etc. Tangible and intangible There is a disadvantage above.

In addition to these systems, portable or mobile engine power generation systems are also in practical use, but they are unsuitable for regular use as fixed stations.

The present invention was made in view of these drawbacks, and provides a method for constructing a power station building that can prevent damage to various equipment, reduce costs, shorten construction period, etc. when constructing an uninterruptible power supply plant. The purpose is to obtain.

In order to achieve this objective, the present invention installs an engine generator and necessary related equipment within the power supply area in a factory, completes internal connections such as wiring and piping for each of these equipment, and at the same time installs a power supply plan within the plant construction site. A mounting stand for the engine generator and a mounting stand for the engine generator facing from below within the frame holding the engine generator are constructed separately, and the power plane is transported there and used as the installation stand for the power drawing. The power supply station building is constructed by removing the frame and fixing the engine generator to the engine generator installation stand.

Embodiments of the present invention will be described in detail below with reference to FIGS. 2, 3, and 4.

Figure 2 is a cross-sectional view of a power station building assembled in a place with a good working environment, such as a factory.
It is assembled based on the power plane 5 which has been formed.

In the room 5a of the power plane 5, an engine generator 3 and related equipment 4 necessary for operating the engine generator 3 are installed and fixed.

Note that the frame 6 on which the engine generator 3 is attached is fixed to the floor within the power plane 5 so that it can be removed on site as described later.

After that, wiring or necessary piping between each device is completed to complete the internal connections.

Therefore, if it is necessary to perform a trial run, it is possible to perform the trial run on the spot, that is, at an assembly site such as a factory, by temporarily connecting to the outside.

The power station building assembled in this way is designed to cover the opening in the power side 5 in consideration of waterproofing during transportation, etc.

To avoid unnecessary damage and to facilitate handling, do not install protruding parts such as ventilation ducts or eaves at entrances and exits.

Next, as described above, the power station building with each of the devices 3 and 4 attached thereto is transported as is to a power plant construction site in a remote location by large truck, trailer, ship, or the like.

It is also possible to take this transportation into consideration and make the power plane 5 have a container structure.

On the other hand, at the power plant construction site, a strong power installation stand γ made of concrete or the like to support the power plane 5 as shown in Figure 3 is installed in advance, and the power Place and fix surface 5.

In addition, when installing this electric power drawing installation stand 1, an installation stand 8 for an engine generator that supports the engine generator 3 is provided separately from this installation stand 7, and this installation stand 8 is It is formed at a position and height facing the inside of the frame 6 on the power plane 5.

After that, install external wiring, ventilation ducts, eaves at entrances and exits, etc.

Next, the fixation of the engine generator 30 to the frame 6 is released, and a chain block 10 is attached to the eye beam 9 provided on the engine generator 3, and the engine generator 3 is slightly lifted by this chain block 10.

After that, the frame 6 that fixed the engine generator 3 to the floor was removed, and the engine generator installation stand 8 that had been formed in advance was removed.
The engine generator 3 is lowered and fixed on top.

According to the present invention, it is also possible to form a power plane that can be divided and assembled into a plurality of pieces as shown in FIG. 4, thereby making transportation convenient.

It is also possible to create a power plant in which multiple engine generators work together.

As is clear from the above explanation, in the present invention, each device is fixed in the power plant and transported with wiring, piping, etc. completed, so that a power plant using an engine generator can be transported to a remote location without damage. Can be transported safely.

In addition, before transportation, we carry out internal installation work, wiring, piping, etc. necessary for power plant operation, such as fuel tanks, engine generator control panels, rectifiers, batteries, ventilation fans, outlets, indoor lighting equipment, and switchboards, at a factory with a good working environment. Moreover, since it is completed in advance by a skilled engineer, a trial run of the power plant can be carried out before transportation.

Therefore, the work that must be carried out in unfavorable environments or conditions after being transported to a remote location can be greatly reduced, making it possible to start operating a power plant in a short period of time, and making it possible to provide a high-quality, highly reliable power source. It has the advantage of being able to provide plants.

At present, the engine generator is installed in the power plant via a frame at the factory, and at the power plant construction site, the frame is removed and fixed to a pre-installed installation stand for the engine generator, so it is relatively environmentally friendly. Alternatively, all wiring and piping related to the engine generator can be done at a factory with good conditions, and necessary trial runs and tests can also be carried out.

Still, there is an economical advantage in terms of materials and work efficiency, as it does not require packaging or unpacking of the engine generator or related parts during transportation.

In addition, installation of the engine generator on-site can be done by simply raising the engine generator slightly without moving it, and there is no need to change wiring, piping, etc., and there is also no need to change the wiring or piping, etc. It has the advantage of being easy to work with anywhere.

Furthermore, since the engine generator is fixed on an independently installed engine generator mounting stand, the vibrations generated during operation are not transmitted to other equipment via the power side, and therefore the power side , the vibration resistance of equipment can be made simple.
