Description

[Detailed Description of the Invention] The present invention relates to the structure of a portable generator that generates electricity using engine power.

The structure of a conventional portable generator is shown in FIGS. 1 and 2. A radiator 2, a fan 3, and an engine 4 are installed in a generator cover 1 of a box-shaped portable generator installed on a common pedestal 9. ,
A generator 5 is installed, and an engine room e is installed in the generator cover 1.
In the case of a soundproof continuous generator, the surrounding area is sealed with a soundproof wall, and there is a door 6 for inspecting the engine room e, and an intake louver 7 for entering the engine room e. A radiator exhaust duct 10 of the engine 4 is formed by providing a partition plate 10a of the engine room e provided and a baffle plate 10b extending over the bottom of the generator cover 1 and radiator 2 to guide the exhaust air of the radiator 2 upward. An exhaust port 8 is provided in the upper part of the generator cover 1 of the exhaust duct 10, and when the generator is in operation, air is taken in from the intake louver 7 to the exhaust duct 10 of the radiator 2.
is configured to be guided to the exhaust port 8 by a baffle plate 10b and exhausted, thereby achieving cooling ventilation in the engine room E and soundproofing effect.

11 is a fuel tank.

However, as shown in FIG. 3, when using the portable generator A, a large number of loads P1. P2. When power is supplied to P3, power is supplied via the branch switchboard 13a.

In addition, as shown in Fig. 4, the portable generator A is connected from the regular power supply P4.
When switching to the power supply P5 to supply power to the load P6, power is supplied via the power supply switching panel 13b.

Also, as shown in Figure 5, there are two portable generators A.

When B is operated in parallel to supply power to the load P7, power is supplied via the parallel operation panel 13c.

Reference numeral 14 denotes a control panel incorporating the power supply switching panel 13b and the parallel operation panel 13c.

As shown in each usage example above, related equipment (hereinafter referred to as related equipment) for electrically connecting with the load side or other portable generator side.

) is used by assembling and arranging the necessary equipment each time depending on the type of load side and power supply status.

Therefore, not only is assembly and wiring complicated and time-consuming, but also the number of parts increases during transportation, making it very inconvenient.

In addition, if such equipment is to be housed within the generator cover, it must be installed in a location where it will not interfere with inspection, and special space is required to install it, and the length of the generator cover and This invention eliminates the above-mentioned drawbacks, such as increased width, and replaces the above-mentioned space with almost no change in the size of the conventional generator cover, and which does not affect inspection and maintenance in any way. There are places where equipment can be installed.

In order to achieve this purpose, the present invention forms an exhaust duct with an exhaust duct side plate arranged at a position slightly wider than the width of the radiator and an air guide plate fixed between the exhaust duct side plate. , a related equipment unit for forming a space inside the generator cover with the generator cover, the exhaust duct side plate, and the partition plate, and electrically connecting the exhaust duct side plate to the load side or other portable generator side. is provided in the unit space, and a door for maintenance of the related equipment unit is provided on the side wall covering the generator located in the space.

One embodiment will be described below with reference to FIGS. 6 to 8.

In the drawings, the same reference numerals as in FIGS. 1 to 4 indicate the same parts.

The radiator exhaust duct 10' includes a partition plate 10a that partitions the engine room E, an exhaust duct side wall 10'a that is fixed to the generator cover 1 and the partition plate 10a at a position slightly wider than the width of the radiator 2, and a partition plate 10a that partitions the engine room E. The space is defined by the side wall 10' and the wind guide plate 10'b provided over the bottom of the generator cover 1 and the radiator 2, and the generator cover 1, the partition plate 10a, and the exhaust duct side wall 10'a form a space. Sections C and D are provided with a unit of related equipment 13 (for example, a branch switchboard 13a, a power switchboard 13b, etc.) on the side wall 10'a and arranged in the space sections C and D,
Doors for maintenance of related equipment 13 are provided on the side walls of the generator cover 1 located in spaces C and D, respectively.

With the above configuration, as shown in FIG. 9, a large number of load side P1. P2. It also becomes easier to feed power to P3.

Furthermore, as shown in FIG. 10, it is also easy to switch from the regular power source P4 to the power source of the portable generator A to supply power to the load P6.

Furthermore, as shown in Figure 11, two portable generators A and B are installed.
When operating in parallel to supply power to the load P7, it is simple as in the previous embodiment.

Of course, these related equipment 13 may be a combination of a load side and another portable generator.

As shown in the above embodiments, when the present invention is used in connection with the load side or other portable generator, the wiring becomes very cylindrical, which saves the effort required for the combination, and reduces the need for the generator cover. Since the size is almost the same as the conventional one, it is easy to transport with fewer parts, and since all of these related devices are unitized, they are compatible when installed and can be removed and removed as necessary. Therefore, it is economical to install only the necessary units each time.

Another effect is that the side wall 10'a of the exhaust duct 10'
and the side wall of the generator cover 1, the effects of the present invention are remarkable, such as being able to reduce the noise of the radiator fan 3 compared to the conventional one.
