Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ground-mounted or floating package type power generation equipment that can be transported by floating.

Traditionally, the construction of a thermal power plant begins with civil engineering work at the site where the power plant is constructed, followed by construction of the foundation for the turbine generator, construction of the turbine building, construction of the boiler steel frame, raising the boiler drum, and installation of various equipment, etc. Component equipment was being installed as civil engineering and turbine building construction progressed.

At sites with poor local installation conditions, these installation works require a long period of time and have a large impact on power plant construction prices.

Furthermore, it is important to transport and bring in each element of the power plant's component equipment in accordance with the installation period, which increases transportation costs.

In particular, securing skilled engineers is a problem for power plants built in underdeveloped areas.

On the other hand, recently boiler. Power plant components such as turbines, generators, transformers, and their auxiliary equipment, as well as the turbine building, are installed on a floatable platform, fabricated and assembled in a single huge package in a factory, and this package is submersible. After purging, the power plant is transported in one piece using waterways such as sea or rivers to near the power plant construction site, towed to a pre-prepared installation location, and placed on the ground by injecting water into the ballast tank installed on the ship's platform. Electricity outside the package, on top of backfill.

A packaged power generation plant system is being considered that would greatly shorten the on-site installation period by connecting to water, fuel equipment, etc., and manufacture power generation equipment in-house with sufficient quality control.

An example of a bed-mounted package type power generation facility will be explained below using the drawings.

Reference numeral 20 in the figure is a turbine generator building for protecting these devices.

Each of these devices that make up the power generation package is manufactured in a short period of time under strict control at a factory, and then assembled and mounted on the cradle 1! Sill.

FIG. 4 is a diagram showing a state in which the power generation package P is transported on water. In the figure, P is the power generation package, and B is a submersible purge for mounting the power generation package (2).

Further, T is a towing boat for towing this submersible purge B, and S is a waterway, such as the sea.

In this way, the power generation package is towed close to the power plant construction site by the towing vessel T.

In this way, a packaged power generation plant can be assembled in one go at any location by the manufacturer, including the power generation plant equipment and the building that houses it, and can be installed at any location that can be transported by water. can.

It is also clear that the power generation package described above can be used as a mobile power station for transmitting generated power to land for a predetermined period of time by fixing it floating on water instead of being fixedly installed on land.

However, in order to install or fix the power generation package completed at the factory at the specified location for power plant construction and to enable safe operation, it is necessary to safely transport the completed power generation package using transportation purge, and to construct the power plant after transportation. Safe and quick movement and installation into position is important.

The reason why packaged power generation equipment was not common in the past was because
Safe transportation was considered impossible due to various technical problems such as lashing methods for transportation, and there were also technical problems in moving and installing large and extremely heavy objects safely and quickly to the designated location for power plant construction. This is due to the fact that the problem was not resolved.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention aims to provide a packaged power generation facility that can be transported safely and quickly moved and installed.

Therefore, in the present invention, protrusions are provided on the side surfaces of the power generation package to which wires can be hung, with the mounting positions shifted on the left and right sides, making it convenient for towing by a tugboat, pulling into a designated position for power plant construction, and fixing the power plant. When accumulating and installing multiple power generation packages, the configuration should be such that the distance between adjacent packages can be minimized.

An embodiment shown in FIGS. 5 to 8 will be described below.

Figure 5 is a plan view of the side of the power generation package, with the mounting positions shifted on the left and right sides, and a protrusion on which a wire can be hung. Figure 6 is a diagram showing an example of a protrusion on which a wire can be hung.
The figure is a diagram for explaining how to pull the power generation package into the designated position for construction using the protrusion provided on the side of the power generation package and the 2-inch part provided on the land 1. Figure 8 shows two power generation packages. It is an explanatory diagram showing an enlarged view of the vicinity of the protrusion when the is installed (9) and fixed.

In the figure, P is the power generation package, Pl is the 1st door, P2
is a two-way power generation package, H is a ditch for pulling the power generation package P into the designated location for power plant construction, W is a winch installed on land, R is a lead-in wire, and SB is land and sea.

Alternatively, the border line between land and river, etc., T is a tag board that assists in pulling in, and 21 is a protrusion provided on the side of the power generation package P to which a wire can be hung.

The power generation package P (also Pl or P2) itself is manufactured in a strictly controlled domestic factory based on an appropriate equipment layout plan as described above.

However, in accordance with the production of the power generation package P, a plurality of protrusions 21 to which wires can be hung are attached to both sides of the power generation package P at different positions on the left and right sides.

An example of the protrusions 21 is shown in FIG. 6, and the number of protrusions 21 is determined by the number of protrusions 21 to be towed by a tugboat to a predetermined location for power plant construction after transportation, and to be pulled in and fixed by a winch W provided on land, which will be described later. Make the numbers useful and effective.

Furthermore, the protrusion 21 is attached to the completed power generation package P.
As mentioned above, it will be loaded onto the transport purge B and transported to a location close to the planned construction site of the power plant.

After transportation, it will be towed to the designated location for power plant construction using a tugboat or tugboat T, but if it is close to land, a winch or the like will be used to tow it safely and quickly.

FIG. 7 illustrates an example of this. Power generation package P
A wire R is used to connect the protrusions 21 provided on both sides of the winch W and a winch W provided on land, and the wire R is pulled into the planned construction location using a ditch H, etc., and the tugboat T is used for assistance. Move and fix while receiving.

In this case, if there is no protrusion on the side surface of the power generation package P, the winch W provided on land is of no use for retracting and fixing, and only the tugboat T is used for retracting and fixing.

Needless to say, in the case of retracting and fixing using only tugboats, it is not possible to quickly retract and secure, let alone move to an accurate position.

FIG. 8 shows two power generation packages P1. An example of the installation of P2 is shown.

When installing multiple power generation packages, it is required to configure the power plant and to minimize the distance between adjacent power generation packages for safe operation and convenient maintenance and inspection.

It goes without saying that if this method is adopted, only the space for the protrusion 21 is required and the distance between adjacent power generation packages can be minimized.

As described above, the present invention has the effect of solving the technical problems of safely and quickly moving and installing the power generation package to a predetermined location for power plant construction, and enabling a beneficial power plant configuration.
