Abstract

PURPOSE:To make a power generating set compact and to reduce its weight by installing a generator on a horizontal water-cooled engine and by fitting a cooling system such as a cooling water pump and cooling fan, etc. to the engine. CONSTITUTION:An AC generator 5 is installed on a horizontal water-cooled engine 1. A radiator 12, cooling water pump 15, and cooling fan 15a are fitted to the engine 1, which drives the AC generator 5 through a driving V pulley 3, V belt 9, and driven V pulley 6. Accordingly, no common platform is required, thereby the weight is reduced and the cost is lowered. Furthermore, the power generating set is made compact, thus the packing volume is reduced and the cost for packing and transportation can be lowered.

Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to improvements in generator sets based on internal combustion engines.

Figure 1 (a) shows a power generation set using a conventional horizontal water-cooled engine.

Pulley, 05 is driven side V-boo 9, 06 is flywheel,
07 is a fuel tank. in this case.

Since the engine 01 and the generator 02 are mounted on a common base plate 03, there are the following drawbacks: (1) The total length when 1 generating set J), i/) becomes long.

(2) Shipping costs will increase as the number of packaging customers increases.

, 3) Production near X) - (Ah cost 2 common base plate) one. - Goods,
The amount increases.

1 (4) In less developed countries, transportation capacity is limited, and there is a high risk of damage during transportation for items with large packaging volumes.゛The purpose of the present invention is to focus on the above-mentioned points, take into account the local transportation capacity for export, to reduce costs by making the duct as compact as possible, reducing weight, and reducing the number of parts, and to reduce packaging costs and shipping costs. The purpose of the present invention is to provide a power generation set using an internal combustion engine that can achieve savings, and its feature is that a horizontal water-cooled engine and a generator are not mounted on a common base plate.

The above generator is mounted on the top of the above engine, and the cooling water pump,
The above engine was equipped with a cooling device such as a cold lung fan.

In this case, there is almost no change in the overall length between the two engines alone and when they are in the generator set state, and the weight can be reduced because a common base plate is not required.

Embodiments of the present invention will be described below with reference to the drawings.

It is shrink-fitted to the shaft 5a.

It is connected to the drive V-pulley 3 by a belt 9.

Reference numeral 10 denotes a radiator mounting frame, which is suspended from the end of the alternator mounting plate 7 with ports 11, and the radiator 12 is attached to the radiator mounting frame 10 with gels 13.

15 is a cooling water pump, driven by V-boo IJ15b and
The cooling fan 15a is attached to the mounting plate 14 by a gel 16.

Reference numeral 17 denotes a V-belt for driving the cooling water pump 15, which connects the driving V7°-IJ 3a and the driven Vf-IJ 15b on the cooling water pump side.

The operation in the case of the above configuration will be described.

The horizontal water-cooled engine 1 is a prime mover that drives an alternator 5, and power is transmitted from a driving side V-pulley 3 attached to a flywheel 2 to a driven side V-pulley 6 via a 6V belt 9. Ru.

Since the rotation speed of the alternator 5 needs to be at a synchronous speed, the pulley diameter is determined in consideration of the Gooley ratio of the driving side V-pulley 3 and the driven side V-pulley 6.

The engine is operated at a constant rotation speed.

The radiator 12 and the cooling fan 15a are devices for cooling engine cooling water, and the cooling water pump 15 has a function of circulating the cooling water.

On the other hand, the driving of the cooling water pump 15 and the cooling fan 15M is transmitted from the drive side V7'-reel 3a to the driven side Vf-reel 15b via the V-belt 17.

As mentioned above, in the past, the engine and generator were set on the same plane on a common base plate as shown in Figure 1, but in the present invention, the first effect is achieved by mounting the generator directly on top of the engine. Ru.

(1) Since a common base plate is no longer required, weight can be reduced by 90%, which is a huge improvement over the conventional model.

(2) The power generation set status becomes disconnected.

(3) With regard to packaging, the packaging volume is reduced, making it possible to reduce packaging costs and shipping costs.

The horizontal water-cooled engine 1 is a prime mover for driving an alternator 5, and the power is transmitted from the drive side V, f-93 attached to the flywheel 2 to the driven side pulley 6 via the V belt 9. communicated.

Since the alternating current generator's 50 rotational speed requires a synchronous speed, the Gooley diameter is determined in consideration of the sheer ratio of the driving side V7''-173 and the driven side V pulley 6.

The engine is operated at a constant rotation speed.

The condenser 29 and the cooling fan 24 are devices for cooling the chilled water of the engine.
