Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency power generator for generating electric power by using liquid fuel such as light oil or heavy oil.

[0002]

2. Description of the Related Art An emergency power generator is constructed so that a generator is rotated by a diesel engine or a gas turbine engine. Therefore, as fuel for the emergency power generator,
Light oil or heavy oil is used.

The capacity of the fuel tank that can be mounted on this emergency power generation device is determined by the Fire Service Law as follows. That is, "The capacity of the fuel tank should be less than one-fifth of the quantity (hereinafter referred to as the designated quantity) specified by the Cabinet Order concerning the regulation of dangerous substances of the fuel used, and the capacity that can be operated for 2 hours or more at the rated output. The designated quantity was set as shown in the table by the revision in March 1990.

[0004]

[Table 1]

Due to such restrictions, the fuel tank is generally mounted on the power generator when the operation time is 2 to 3 hours, and is separate from the power generator when the operation time is longer than that. Is installed in.

Next, the structure of the emergency power generator is shown in FIG. In the figure, 1 is a diesel engine, 2 is an alternator,
3 is a battery, 4 is a fuel tank, 5 is a radiator, 6
Is a muffler, 7 is an automatic start generator panel, 8 and 9 are intake holes, 1
Reference numeral 0 is an exhaust hole. Since the fuel tank 4 is mounted on the common base 11 to which the diesel engine 1, the AC generator 2, etc. are mounted, a large capacity tank cannot be installed. Also,
Since the operating time of the diesel engine 1 is short when the fuel tank is small, a separate tank is installed.

As shown in FIG. 3, the separate tank 12 is arranged at a position separated from the diesel engine 1 by S = 2 m or more, and separated by a = 50 cm or more from the separate tank 12 by the Fire Service Law regardless of indoors or outdoors. The height is about 30 cm and the thickness is t = 10 to prevent the fuel from flowing out at a distance.
An oil barrier 13 of cm is provided, and a waterproof mortar 14 is provided on the floor surface on which the separate tank 12 is placed. Besides, an oil sump 15 is provided on the floor surface.

[0008]

However, since it is mounted on a common base, the capacity of the tank cannot be increased, and therefore the operating time of the emergency power generator is short, and it is not preferable to refuel while operating.

On the other hand, in order to provide a separate tank, an oil barrier is required, which not only increases the installation space for the emergency power generator, but also requires construction costs and is not preferable in appearance.
In addition, if an oil levee is installed outdoors, rainwater will collect inside the oil levee, and it will be necessary to take measures against mold and the like. Further, depending on the jurisdiction of the fire department, there are cases where it is required to provide a roof or a double fence on an outdoor tank, or to install a rainwater separation detector or the like inside the oil barrier.

Therefore, an object of the present invention is to provide an emergency power generator that solves the above problems.

[0011]

The structure of the present invention for achieving the above object is to provide a common base on the bottom of the housing and fix the generator and the drive means for driving the generator on the common base. However, the fuel tank is arranged on the upper part of the housing, and the fuel tank is fixed to the housing, and the fuel tank is set to a size that can satisfy the maximum value of the capacity derived from the specified quantity.

[0012]

[Function] Since the fuel tank is placed on the upper space of the housing without mounting the fuel tank on the common base with a small space for mounting the generator and the driving means, it is possible to increase the capacity of the fuel tank. It can be set to the maximum value specified. Therefore, it is not necessary to provide a separate tank.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is intended to eliminate the need for a separate tank by increasing the capacity of the tank installed in the emergency power generation device within the range of regulation by the Fire Service Law. Since the Fire Service Act was amended in March 1990 and the specified quantity has increased (gas oil and kerosene have doubled), the present invention has great significance.

The present invention will be described in detail below with reference to FIG. As shown in the figure, the common base 11 is provided at the bottom of the package 17 as a housing whose six sides are covered.
A generator 2 and a diesel engine 1 equivalent to 200 KVA are mounted on the top. The fuel tank 4 is arranged above the generator 2 in the upper part of the package 17.
The fuel tank 4 has a capacity of 350 to 395 liters, which is the maximum value of less than 1/5 of the designated quantity. Since the fuel tank 4 is heavy, four columnar reinforcing members 18 are erected on the common underframe 11 and provided on this reinforcing member 18. A heat insulating material 19 is provided around the fuel tank 4, an instrument panel 21 provided with an oil amount gauge 20 for knowing the amount of fuel in the fuel tank 4, and the fuel is supplied from the outside into the fuel tank 4. And a wing pump 22 for Further, the package 17 is provided with an inspection door 24 for directly seeing the amount of fuel through a gauge 23 separately provided in the fuel tank 4, and an inspection lid 25 is provided on the upper surface of the package 17. The muffler of the generator 1 is
Since it is also affected by radiant heat, it will be suspended from the ceiling if it is installed indoors, and it will be installed separately as a floor-standing stand if installed outdoors. The wiring material and the piping material are not transferred from the bottom portion or the lower portion of the side surface of the fuel tank 4 in case of an accident, but are connected near the upper surface of the fuel tank 4.

Next, the operation of the emergency power generator will be described. Since the fuel consumption of the diesel engine 1 is 50 liters / hour when A heavy oil is used as fuel,
7- because the tank capacity is 350-395 liters
The emergency power generator can be operated for 7.5 hours.
When the fuel in the fuel tank 4 is reduced, the wing pump 22 can be operated after stopping the operation of the emergency power generator to supply the fuel into the tank 4 from a container (not shown).

As the drive means, a gas turbine may be used instead of the diesel engine. Further, the structure of the package (or enclosure) used as the housing may be any of a normal type, a disaster prevention type, and a low noise type according to the private power generation facility standard of the Fire Service Law.

[0017]

As can be seen from the above description, according to the emergency power generator according to the present invention, the fuel tank is arranged in the upper part of the housing, so that the conventional common floor having the generator and the driving means is installed. It is possible to increase the capacity of the fuel tank as compared with the case where the fuel tank is arranged in. Therefore, the continuous operation time of the emergency power generator can be significantly increased as compared with the conventional one. In other words, since the fuel tank is not installed on the common floor, the installation space for the emergency power generator can be reduced.

Further, since the capacity of the fuel tank can be increased, it is not necessary to provide a separate tank, and all the problems such as the need for an oil barrier are solved.
