Description

(54) POWER STATION BUILDING (71) We, MASCHINENFABRIK AUGSBURG NURNBER AKTIENGESELLSCHAFT, a German company, of 8900 Augsburg, Stadtbachstrasse 1, Federal Republic of Germany, do hereby decIare the invention, for which we pray that a patent may be granted to us.

and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to a power station building with an engine house for one or more internal combustion engine and generator and separate compartments for accommodating electrical switching and control arrangements as well as accommodating operating staff and plant equipment.

In the case of known power station installations of the kind preferred in areas with badly developed infrastructure, e.g.

poor transport systems and facilities, the engine house and the places for accommodating the electrical switching and control arrangements as well as the operating staff are disposed respectively in parts of the building which are separated from each other. Separate foundations are required for each of these parts of the building as well as for the machine parts to be disposed outside the engine house, such as e.g. intake air filters, exhaust silencers and cooling fan installations. Building material and its transport, concrete foundations and the excavations needed for them, represent a considerable cost factor, especially in areas with bad infrastructure.

The object of the present invention is therefore to reduce the building costs of power station buildings of this kind.

According to one aspect of the present invention there is provided a power station building comprising an engine house adapted for accommodating at least one internal combustion engine and generator, of which at least two opposite side walls consist at least partly of walls of containers forming separate compartments for housing electrical switching and control arrangements as well as accommodating operating staff and plant equipment, and a flat roof of the engine house, which is capabIe of bearing additional arrangements, extends over and is supported on the containers.

For installing the or each internal combustion engine, the engine house is preferably provided with foundations adapted to have at least one internal combustion engine and generator mounted thereon.

The foundations for the containers must be dimensioned more strongly than is the case in unIoaded containers, i.e. ones not carrying a load-bearing roof, but compared with known installations the total foundations of this arrangement in accordance with the invention may require less concrete and fewer excavations, and there may also be a saving in building materials since at least part of the side walls of the engine house are formed by the containers.

A further advantage may arise from a short extent for electrical cables and other supply lines.

It is advantageous for the longitudinal axis of the or each internal combustion engine to be disposed parallel to the side walls, formed from the walls of the containers, of the engine house, whereby a favourable floor plan in the engine house is produced, particularly if several internal combustion engines are juxtaposed.

In order to attain a higher headroom in the engine house, containers can also be superposed.

In a preferred embodiment, the containers are placed on supports at the side in the engine house space whereby the containers are raised above the floor level of the engine house. With this measure, the headroom of the engine house can meet the requirements of the respective engines and generators used; the headroom should be dimensioned such that piston and its connecting rod of an engine can be removed by lifting apparatus attached to the flat roof. Moreover, laying the electric cables and the other supply lines as well as their servicing and checking are facilitated by the space formed under the containers.

The non-supporting end walls of the engine house are preferably suspended from the flat roof, whereby foundations for these end walls are not required. In order to mount and dismount the internal combustion engines these end walls can be secured so that they are also easy to dismount.

It is advantageous for lifting devices, e.g.

crane installations, to be attached to the flat roof.

According to another aspect of the present invention there is provided a method of constructing a power station building comprising disposing two discrete containers, for housing electrical switching and control arrangements, and for accommodating plant and operating staff, having generally planar walls, in spaced apart relationship with facing walls parallel, providing a flat load bearing roof or roof structure extending over and supported on the containers to form a covering for the space between the containers, and providing foundations within the space between the containers adapted to have at least one internal combustion engine and generator mounted thereon, whereby the said space is adapted for use as an engine house of the power station building.

The invention may be carried into practice in a number of ways but one specific embodiment will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a view of a power station building, in accordance with the invention taken on the section line B-B of Figure 2; Figure 2 is a view of the power station building taken on the section line A-A of Figure 1.

In the power station building as shown in Figure 1, internal combustion engines 1 and 2 are mounted on foundation frames 3 and 4 supported on foundations 5 and 6.

The internal combustion engines are connected to generators 7 and 8, which are likewise mounted on the foundation frames 3 and 4.

The opposite, parallel side walls of the engine house of the power station building are formed by the facing side walls of containers 9 and 10 which are supported on foundation plates 15 and 16, which may be pre-formed, by means of intermediate supporting walls 11 and 12 and supports 13 and 14. A flat roof 17 covering the engine house is positioned across the tops of the containers 9 and 10, the roof basically comprising steel girders 18 lying on the containers 9, 10 and cross-beams 20 are attached to these girders in turn in order to support roofing 21. The sides of the flat roof 17 are equipped with covers 22.

Intake air filters 23, 24 and exhaust silencers 25, 26 of the internal combustion engines 1 and 2 are fixed to the roof 17, e.g.

to the steel girders 18, and, connected between the intake filters and the internal combustion engines, there are turbo-superchargers, only the one for the left-hand engine in Figure 1 being labelled 19. The end walls 27, 28 of the power station building, of which only the back end wall 27 can be seen in Figure 1, are likewise suspended respectively from a steel girder 18 of the flat roof 17. Moreover, fans 29, 30 are disposed on the steel girders 18 through which the engine house is ventilated. The fresh air enters through openings 31, 32 provided in the supporting walls 11, 12 and air shafts 33, 34 externally connected to them. Further to this, guide rails 35, 36 for lifting apparatus 37, 38 are attached to the steel girders 18 over the internal combustion engines 1, 2.

Further elements not shown in the drawing, such as e.g. day fuel tanks and water tanks, can also be suspended from the flat roof 17.

The containers 9 and 10 contain electrical switching and control arrangements, to which the cables 39 and 40 coming from the generators are conducted, as well as furniture and furnishings for accommodating power station operating staff. Steps 41 and 42 lead from the containers 9 and 10 into the engine room.

Figure 2 shows the internal combustion engine 1, to whose turbo-supercharger 19 the intake air filter 23 as well as the exhaust silencer 25 are connected. The non-supporting end wall 27 is suspended from the flat roof 17 between the internal combustion engine 1 and the intake air filter 23, and the opposite end wall 28 bascially terminates at the opposite outer edge of the roof. This end wall 28 is attached to the outer steel girder 18 of the flat roof 17 so that it can be removed, in order to make it possible to move the internal combustion engine 1, disposed on the foundation frame 3, and the generator 7 in and out. For this purpose, rails 43 and 44 are disposed on the foundations 5 and 6, the rails leading over the foundations 5 and 6 to the outside. The internal combustion engines 1, 2 and generators 7, 8 disposed on the foundation frames 3, 4 can be moved on the rails 43, 44 by corresponding roller arrangements not shown in the drawing, for the purpose of mounting and dismouting.

The height of the supports 13, 14 as well as of the supporting walls 11, 12 on which the containers 9, 10 are postioned is dimensioned such that an adequate height remains for the lifting apparatus 37, 38 which can be moved on the guide rails 35, 36 in order, for example, to be able to lift an piston and its connecting rod when servicing and overhauling of the internal combustion engines take place.

WHAT WE CLAIM IS: 1. A power station building comprising an engine house adapted for accommodating at least one internal combustion engine and generator, of which at least two opposite
