Summary of the Invention

Problems to be Solved by the Invention

[0004] When installing this type of engine generator set in a basement floor, the entire engine generator set is lifted and carried in, for example, by a crane through a dedicated loading entrance provided on the floor of the upper floor.

[0005] However, in actuality, there are cases where, although it is desired to install the engine generator set in the basement floor, there is no dedicated loading entrance provided on the floor of the upper floor. In such cases, the engine generator set is first disassembled into a plurality of components such as at least an engine, a generator, and a base unit, and the disassembled plurality of components are carried into the basement floor using a loading assistance device such as an elevator, and the carried-in plurality of components are assembled at a predetermined installation position on the basement floor.

[0006] However, the base of an engine-powered generator, in particular, is a component that supports both the engine and the generator, and therefore tends to be large. Even if the base is disassembled into a single unit, it may not fit into the transport support device. In such cases, it becomes necessary to change the installation plan itself, for example, by changing the location of the engine-powered generator or switching to a smaller engine-powered generator.

[0007] Therefore, this embodiment provides an engine-power generator in which the support section for the engine and generator is made more compact so that it can be transported, and a method for installing this engine-power generator. [Means for solving the problem]

[0008] The engine power generation device according to this embodiment comprises an engine that generates power, a generator that generates electricity driven by the power generated by the engine, and a support portion that supports the engine and the generator, the support portion being composed of a plurality of support portion components.

[0009] Furthermore, the method for installing an engine power generation device according to this embodiment includes an engine that generates power, a generator that generates electricity driven by the power generated by the engine, and a support section that supports the engine and the generator, wherein the support section is composed of a first support section component and a second support section component that have different lengths in a predetermined direction, and includes a loading step of loading the engine, the generator, the first support section component and the second support section component using a loading support device; a first support section component fixing step of fixing the first support section component loaded in the loading step to the installation position; an installation step of attaching the engine and the generator to the first support section component fixed in the first support section component fixing step; and a second support section component fixing step of fixing the second support section component loaded in the loading step to the installation position before or after the installation step.

[0011] Hereinafter, a plurality of embodiments related to the engine generator and the installation method of the engine generator of the present disclosure will be described with reference to the drawings. In the plurality of embodiments, substantially the same elements are denoted by the same reference numerals, and the description thereof will be omitted.

[0012] (First Embodiment) The engine generator 100 illustrated in FIG. 1 includes an engine 110, a generator 120, and a base portion 130. The engine 110 generates power by burning fuel. The generator 120 is driven by the power generated by the engine 110 to generate electric power. The base portion 130 supports both the engine 110 and the generator 120 from below. That is, the base portion 130 is a component that functions as a base for the engine 110 and the generator 120. Further, the base portion 130 is also a component that functions as a base for the entire engine generator 100.

[0013] Furthermore, the engine generator 100 includes a pedestal 140 and a control panel 150. The pedestal 140 is an example of a base portion and includes a rectangular pedestal main body portion 141. The pedestal 140 also includes a plurality of legs 142, 143 that linearly extend downward from the corners of the pedestal main body portion 141. Of the plurality of legs 142, 143, the two legs 142 provided on the engine 110 side are an example of the first legs. On the other hand, of the plurality of legs 142, 143, the two legs 143 provided on the side opposite to the engine 110 are an example of the second legs.

[0014] In addition, an instrument panel 144 and a nameplate plate 145 are attached to the side portion of the pedestal main body portion 141. A terminal block 146 is provided on the side portion of the leg 143 of the pedestal 140. A plurality of electric wires (not shown) are connected to the terminal block 146.

[0015] The control panel 150 controls the overall operation of the engine generator 100. The control panel 150 can at least control the operations of the engine 110 and the generator 120, and can monitor the operating conditions of the engine 110 and the generator 120. In this case, the control panel 150 is placed on the pedestal body portion 141 of the pedestal 140. Also, as illustrated in FIG. 2, a battery 160 is also placed on the pedestal body portion 141 of the pedestal 140.

[0016] The engine 110 includes a power transmission shaft (not shown) for transmitting the generated power to the generator 120. Also, legs 111 are provided at the lower part of the engine 110. In this case, the legs 111 are provided at the end of the lower part of the engine 110 on the side opposite to the generator 120.

[0017] On the other hand, the generator 120 includes a rotating body (not shown) that rotates by the power transmitted from the engine 110. The generator 120 can generate electric power, that is, can generate electricity, by rotating this rotating body. Also, legs 121 are provided at the lower part of the generator 120. In this case, the legs 121 are provided at the end of the lower part of the generator 120 on the engine 110 side and at the central part in the axial direction of the lower part of the generator 120.

[0018] In a state where the engine 110 and the generator 120 are supported by the base portion 130, the axis of the power transmission shaft of the engine 110 and the axis of the rotating body of the generator 120 are substantially or completely aligned. Thereby, the engine generator 100 can efficiently transmit the power generated by the engine 110 to the generator 120. Hereinafter, the direction S, which is the axial direction of the power transmission shaft of the engine 110 and also the axial direction of the rotating body of the generator 120, is referred to as the "axial direction S" of the engine generator 100. The axial direction S of the engine generator 100 is an example of a predetermined direction.

[0019] The engine power generator 100 according to this disclosure features particularly ingenious design in the configuration of the base section 130. This point will now be explained in more detail. Specifically, as illustrated in Figure 3, the base section 130 is composed of multiple parts, in this case, two parts: a large part 131 and a small part 132. The large part 131 is an example of a first support section component, and the small part 132 is an example of a second support section component.

[0020] A boundary portion 133 is formed between the large part 131 and the small part 132. The boundary portion 133 extends linearly along a direction perpendicular to the axial direction S of the engine generator 100. At the boundary portion 133, the large part 131 and the small part 132 may be in contact or separated. However, if the large part 131 and the small part 132 are separated at the boundary portion 133, it is preferable to make the separation distance as short as possible.

[0021] The large part 131 includes an engine leg mounting portion 131B and a generator leg mounting portion 131C between a pair of side plate portions 131A that extend linearly along the axial direction S of the engine generator 100. The large part 131 has one engine leg mounting portion 131B. The large part 131 also has multiple, in this case two, generator leg mounting portions 131C.

[0022] Both the engine leg mounting portion 131B and the generator leg mounting portion 131C extend linearly along a direction perpendicular to the axial direction S of the engine generator 100. In other words, both the engine leg mounting portion 131B and the generator leg mounting portion 131C extend linearly along the extension direction of the boundary portion 133. That is, both the engine leg mounting portion 131B and the generator leg mounting portion 131C are provided to be approximately or perfectly parallel to the boundary portion 133.

[0023] As illustrated in Figure 1, the legs 111 of the engine 110 are attached to the engine leg mounting portion 131B of the large part 131. Similarly, the legs 121 of the generator 120 are attached to the generator leg mounting portion 131C of the large part 131. In other words, both the legs 111 of the engine 110 and the legs 121 of the generator 120 are attached to the large part 131.

[0024] Furthermore, the legs 142 of the frame 140 are attached to the large part 131. In this case, the legs 142 of the frame 140 are attached to the part of the large part 131 between the two generator leg mounting parts 131C. Also, the legs 143 of the frame 140 are attached to the small part 132. In this case, the legs 143 of the frame 140 are attached to the end of the small part 132 opposite to the engine 110. In this way, the frame 140 is attached so as to straddle the large part 131 and the small part 132.

[0025] Furthermore, the legs 121 of the generator 120 are made of metal and are electrically connected to the generator leg mounting portion 131C of the large part 131, which is also made of metal. The generator 120 is also grounded by an earth wire 122. Thus, the large part 131 is configured to be grounded via the generator 120 and the earth wire 122.

[0026] Furthermore, the engine generator 100 is equipped with a conductive wire 134 that electrically connects the large part 131 and the small part 132. That is, the small part 132 is electrically connected to the large part 131, which is maintained at ground potential, via the conductive wire 134. Therefore, the small part 132 is also maintained at ground potential, just like the large part 131. In other words, the base part 130, which is composed of the large part 131 and the small part 132, is maintained at ground potential as a whole. The conductive wire 134 is an example of an electrical connection.

[0027] Next, an example of the length relationship of the various parts constituting the engine generator 100 will be described in detail. That is, as illustrated in Figure 1, the engine generator 100 has a configuration in which the length L1 of the large part 131 and the length L2 of the small part 132 are different in the axial direction S. In this case, the length L1 of the large part 131 is longer than the length L2 of the small part 132.

[0028] Furthermore, the engine generator 100 has a configuration in which the length L3 obtained by summing the length L1 of the large part 131 and the length L2 of the small part 132 in the axial direction S, that is, the length L3 of the base part 130 along the axial direction S, is longer than the length L4 of the engine 110 in the axial direction S, longer than the length L5 of the generator 120 in the axial direction S, and longer than the sum of the length L4 of the engine 110 and the length L5 of the generator 120 in the axial direction S, L6.

[0029] Furthermore, the engine generator 100 may be configured such that the total length L3, which is the sum of the length L1 of the large part 131 and the length L2 of the small part 132 in the axial direction S, is longer than the length L4 of the engine 110 in the axial direction S, or longer than the length L5 of the generator 120 in the axial direction S, or longer than the sum of the length L4 of the engine 110 and the length L5 of the generator 120 in the axial direction S, or longer than the sum of the length L6 of the engine 110 and the length L5 of the generator 120 in the axial direction S.

[0030] Furthermore, the engine generator 100 has a configuration in which the total length L6, which is the sum of the length L4 of the engine 110 and the length L5 of the generator 120 in the axial direction S, is longer than the length L1 of the large part 131 in the axial direction S.

[0031] Furthermore, the engine generator 100 is configured such that the length L1 of its large part 131 in the axial direction S is longer than the length L4 of the engine 110 in the axial direction S.

[0032] Furthermore, the engine generator 100 is configured such that the length L4 of the engine 110 in the axial direction S is longer than the length L5 of the generator 120 in the axial direction S.

[0033] Furthermore, the engine generator 100 is configured such that the length L5 of the generator 120 in the axial direction S is longer than the length L7 of the control panel 150 in the axial direction S.

[0034] Furthermore, the engine generator 100 has a configuration in which the length L7 of the control panel 150 in the axial direction S is longer than the length L2 of the small parts 132 in the axial direction S. Also, the engine generator 100 has a configuration in which the length L8 of the frame body 141 of the frame 140 in the axial direction S is the same as the length L7 of the control panel 150 in the axial direction S. Therefore, the engine generator 100 has a configuration in which the length L8 of the frame body 141 of the frame 140 in the axial direction S is also longer than the length L2 of the small parts 132 in the axial direction S.

[0035] The length relationships of the parts of the engine generator 100 described above are merely an example. Therefore, the lengths of the parts of the engine generator 100 can be changed as appropriate.

[0036] However, it is preferable that the engine generator 100 has a configuration in which the length L1 of the large part 131 in the axial direction S is at least longer than the length L4 of the engine 110 in the axial direction S and the length L5 of the generator 120 in the axial direction S.

[0037] Furthermore, it is preferable that the engine generator 100 has a configuration in which the length L2 of the small parts 132 in the axial direction S is shorter than at least the length L4 of the engine 110 in the axial direction S and the length L5 of the generator 120 in the axial direction S.

[0038] Next, the positional relationship of the boundary portion 133 in the engine generator 100 will be explained. That is, as illustrated in Figure 1, the boundary portion 133 is located on the side of the small part 132, which is on the opposite side of the engine 110, from the leg portion 121 of the generator 120, in this case the leg portion 121 on the side of the small part 132, which is on the opposite side of the engine 110. Also, the boundary portion 133 is not located below the engine 110, but below the generator 120.

[0039] Next, an example of the height relationship of the various parts constituting the engine generator 100 will be described in detail. That is, as illustrated in Figure 1, the engine generator 100 is configured such that the upper end H1 of the engine 110 is higher than the upper end H2 of the generator 120.

[0040] Furthermore, the engine generator 100 is configured such that the upper end H3 of the frame body 141, which is the upper end of the frame 140, is lower than the upper end H1 of the engine 110 and higher than the upper end H2 of the generator 120.

[0041] Furthermore, the engine generator 100 is configured such that the upper end H4 of the control panel 150 is higher than the upper end H1 of the engine.

[0042] Next, an example of an installation method for the engine power generator 100 according to this disclosure will be described. That is, as illustrated in Figure 4, the installation method for the engine power generator 100 includes a disassembly process (step S1), a transport process (step S2), a large parts fixing process (step S3), an engine installation process (step S4), a generator installation process (step S5), and a small parts fixing process (step S6).

[0043] Furthermore, the installation method for the engine generator 100 includes a frame installation process (step S7), a control panel installation process (step S8), a large parts grounding process (step S9), and an electrical connection process (step S10).

[0044] In this method of installing the engine power generator 100, the large parts fixing step (step S3) is an example of the first support component fixing step, the engine mounting step (step S4) and the generator mounting step (step S5) are examples of mounting steps, and the small parts fixing step (step S6) is an example of the second support component fixing step. Furthermore, the frame mounting step (step S7) is an example of the base mounting step.

[0045] Next, the details of each step that constitutes the installation method for this engine power generator 100 will be explained. Specifically, as illustrated in Figure 5, in the disassembly step (step S1), the engine power generator 100 is disassembled into, in this case, at least the engine 110, the generator 120, the large parts 131, the small parts 132, the frame 140, the control panel 150, and the battery 160.

[0046] Then, as illustrated in Figure 6, in the loading process (step S2), the engine 110, generator 120, large parts 131, small parts 132, frame 140, control panel 150, and battery 160 are transported to the designated installation location using an elevator EV.

[0047] The elevator EV is an example of a loading support device. As illustrated in Figure 7, in this case, both the vertical length EV1 and the horizontal length EV2 of the elevator EV are shorter than the length L3 of the base portion 130 along the axial direction S of the engine generator 100. That is, the base portion 130 is too large to fit inside the elevator EV when it is not disassembled into large parts 131 and small parts 132.

[0048] In this loading process (step S2), the components of the engine power generator 100 may be placed one by one into the elevator EV and raised and lowered, or, if possible, multiple components may be placed into the elevator EV and raised and lowered at once. That is, for example, relatively small components such as small parts 132, frame 140, control panel 150, and battery 160 may be loaded into the elevator EV simultaneously if possible.

[0049] Then, as illustrated in Figure 8, in the large parts fixing process (step S3), the large parts 131 that were brought in during the delivery process (step S2) are fixed to the floor surface of the designated installation location using fixing members (not shown), such as anchors. Then, in the engine installation process (step S4), the engine 110 is attached to the large parts 131 that were fixed in the large parts fixing process (step S3). In the generator installation process (step S5), the generator 120 is attached to the large parts 131 that were fixed in the large parts fixing process (step S3). Finally, in the small parts fixing process (step S6), the small parts 132 that were brought in during the delivery process (step S2) are fixed to the floor surface of the designated installation location using fixing members (not shown), such as anchors.

[0050] The large part 131 is fixed in the large part fixing process (step S3), and the small part 132 is fixed in the small part fixing process (step S6), thereby forming a base portion 130 consisting of the large part 131 and the small part 132 on the floor surface of the predetermined installation location.

[0051] Then, as illustrated in Figure 9, in the frame mounting process (step S7), the legs 142 of the frame 140 are attached to the large part 131, and the legs 143 of the frame 140 are attached to the small part 132. As a result, the frame 140 is mounted so as to straddle the large part 131 and the small part 132. In the control panel mounting process (step S8), the control panel 150 is placed on the frame body 141 of the frame 140. At this time, it is also preferable to place the battery 160 on the frame body 141 of the frame 140.

[0052] Furthermore, in the large part grounding process (step S9), the generator 120, which is electrically connected to the large part 131, is grounded by the ground wire 122. This grounds the large part 131 via the generator 120 and the ground wire 122. In the electrical connection process (step S10), the large part 131 and the small part 132 are electrically connected by the conductive wire 134.

[0053] By electrically connecting the small part 132 to the large part 131, which has been grounded by the large part grounding process (step S9) (step S10), the small part 132 can also be grounded. Therefore, the electrical connection process (step S10) is also an example of a second support component grounding process.

[0054] Furthermore, if the engine generator 100 has already been disassembled into multiple components prior to the implementation of this installation method for the engine generator 100, the disassembly step (step S1) can be omitted.

[0055] Furthermore, regarding the large parts fixing process (step S3) and the small parts fixing process (step S6), the small parts fixing process (step S6) may be performed before the large parts fixing process (step S3), or the large parts fixing process (step S3) and the small parts fixing process (step S6) may be performed simultaneously.

[0056] Furthermore, regarding the engine installation process (step S4) and the generator installation process (step S5), the generator installation process (step S5) may be performed before the engine installation process (step S4), or the engine installation process (step S4) and the generator installation process (step S5) may be performed simultaneously.

[0057] Furthermore, the small parts fixing process (step S6) may be performed before the engine installation process (step S4) and the generator installation process (step S5), or it may be performed simultaneously with the engine installation process (step S4) and the generator installation process (step S5).

[0058] Furthermore, the order in which the frame installation process (step S7), control panel installation process (step S8), large component grounding process (step S9), and electrical connection process (step S10) are performed can be freely changed. Also, at least two or more of the frame installation process (step S7), control panel installation process (step S8), large component grounding process (step S9), and electrical connection process (step S10) may be performed simultaneously.

[0059] In the engine power generation device 100 illustrated above, the base section 130 supporting the engine 110 and generator 120 is composed of multiple parts, namely large parts 131 and small parts 132. With this configuration, the base section 130 can be transported by dividing it into large parts 131 and small parts 132. Therefore, the base section 130 supporting the engine 110 and generator 120 can be made more compact and transported to the designated installation location.

[0060] Furthermore, in the engine generator 100, the length L1 of the large part 131 and the length L2 of the small part 132 are different in the axial direction S, and in this case, the length L1 of the large part 131 is longer than the length L2 of the small part 132. With this configuration example, both the engine 110 and the generator 120 can be supported by the large part 131. That is, the engine 110 and the generator 120 can be supported by a common large part 131, and after installation, misalignment between the axis of the power transmission shaft of the engine 110 and the axis of the rotating body of the generator 120 can be suppressed.

[0061] Furthermore, according to the engine generator 100, the total length L3 obtained by summing the length L1 of the large part 131 and the length L2 of the small part 132 in the axial direction S, that is, the length L3 of the base part 130, is longer than the length L4 of the engine 110 in the axial direction S, longer than the length L5 of the generator 120 in the axial direction S, and longer than the total length L6 obtained by summing the length L4 of the engine and the length L5 of the generator 120 in the axial direction S.

[0062] In other words, the engine power generator 100 makes it possible to create a base portion 130 that is larger than the engine 110 and generator 120, even though the base portion 130 is composed of multiple divisible parts 131 and 132. As a result, even though the base portion 130 is composed of multiple parts, such as a large part 131 and a small part 132, the base portion 130 can adequately support the engine 110 and generator 120.

[0063] Furthermore, according to the engine generator 100, the sum of the length L4 of the engine 110 and the length L5 of the generator 120 in the axial direction S, L6, is longer than the length L1 of the large part 131 in the axial direction S. Also, the length L1 of the large part 131 in the axial direction S is longer than the length L4 of the engine 110 in the axial direction S. Also, the length L4 of the engine 110 in the axial direction S is longer than the length L5 of the generator 120 in the axial direction S. Also, the length L5 of the generator 120 in the axial direction S is longer than the length L7 of the control panel 150 and the length L8 of the frame body 141 of the frame 140 in the axial direction S. Also, the length L7 of the control panel 150 and the length L8 of the frame body 141 of the frame 140 in the axial direction S are longer than the length L2 of the small part 132 in the axial direction S.

[0064] In other words, in the engine generator 100, the length relationship L6>L1>L4>L5>L7(=L8)>L2 holds true, meaning that the length L2 of the small part 132 in the axial direction S is the shortest. With this configuration example, the length L2 of the small part 132 in the axial direction S can be minimized, and the length L1 of the large part 131 can be made as long as possible. This prevents the large part 131 that supports the engine 110 and generator 120 from becoming unnecessarily small, and makes it possible to realize a large part 131 of a size that can adequately support the engine 110 and generator 120.

[0065] Furthermore, in the engine-power generator 100, the legs 111 of the engine 110 and the legs 121 of the generator 120 are both attached to the large part 131. With this configuration, vibrations generated from the engine 110 and generator 120 can be efficiently absorbed by the large part 131, which is a relatively large component. In addition, the large part 131, being a relatively large component, can stably support the large and heavy engine 110 and generator 120.

[0066] Furthermore, according to the engine power generator 100, the boundary portion 133 formed between the large part 131 and the small part 132 is located on the opposite side from the engine 110 from the leg portion 121 of the generator 120. In other words, according to the engine power generator 100, the boundary portion 133 is formed at a position a certain distance away from the engine 110. With this configuration example, it is possible to suppress vibrations and noises generated from the engine 110 from affecting the boundary portion 133. In addition, it is possible to suppress the large part 131 and the small part 132 from resonating due to vibrations and noises generated from the engine 110, and consequently, the entire base portion 130 from resonating.

[0067] Furthermore, in the engine-powered generator 100, the boundary section 133 is located below the generator 120 and not below the engine 110, which is prone to generating vibrations and noise. In other words, the engine-powered generator 100 achieves a configuration in which vibrations and noise generated from the engine 110 are less likely to affect the boundary section 133.

[0068] Furthermore, in the engine power generator 100, the engine leg mounting portion 131B and the generator leg mounting portion 131C are provided so as to follow the boundary portion 133 and be substantially or completely parallel to the boundary portion 133. In this configuration example, the engine leg mounting portion 131B and the generator leg mounting portion 131C, which are along the boundary portion 133, and especially the generator leg mounting portion 131C which is close to the boundary portion 133, can provide the effect of reinforcing the boundary portion 133.

[0069] Furthermore, in the engine generator 100, the frame 140 has legs 142 attached to the large part 131 and legs 143 attached to the small part 132, and is mounted so as to straddle the large part 131 and the small part 132. With this configuration example, the frame 140 can be used as a mounting base on which components such as the control panel 150 and the battery 160 are placed, and can also be used as a connecting part that links the large part 131 and the small part 132. In addition, the connecting function of the frame 140 can prevent the small part 132 from being misaligned with the large part 131, or in other words, prevent a part of the base 130 from becoming distorted.

[0070] Furthermore, the engine generator 100 is equipped with a conductive wire 134 that electrically connects the large part 131 and the small part 132. In this case, since the large part 131 is grounded via the generator 120 and the ground wire 122, the small part 132 can be indirectly grounded by electrically connecting the small part 132 to the large part 131 via the conductive wire 134. In addition, even though the base section 130 is composed of multiple parts 131 and 132, the entire base section 130 can be maintained at ground potential.

[0071] (Second Embodiment) The engine generator 200 illustrated in Figure 10 is equipped with a lubricating oil inlet / outlet section 201. The lubricating oil inlet / outlet section 201 is a component for supplying and discharging lubricating oil to and from the engine 110. Specifically, the lubricating oil inlet / outlet section 201 includes an inlet 201A through which lubricating oil flows in, and an outlet 201B through which lubricating oil flows out. The engine 110 is also provided with a lubricating oil supply port and a lubricating oil discharge port, which are not shown. The lubricating oil flowing in from the inlet 201A is supplied into the engine 110 from the lubricating oil supply port of the engine 110 and discharged from the lubricating oil discharge port of the engine 110. The lubricating oil discharged from the lubricating oil discharge port of the engine 110 then flows out from the outlet 201B.

[0072] In the engine-powered generator 200 configured in this way, the lubricating oil inlet / outlet section 201 is located further towards the engine 110 than the leg portion 121 of the generator 120, in this case, the leg portion 121 on the engine 110 side. In contrast, the boundary section 133 is located further away from the engine 110 than the leg portion 121 of the generator 120, in this case, the leg portion 121 on the opposite side of the engine 110. That is, according to the engine-powered generator 200, the boundary section 133 is formed at a position a certain distance away from the lubricating oil inlet / outlet section 201.

[0073] According to this configuration example, even if lubricating oil leaks at the lubricating oil inlet / outlet section 201, it is difficult for the lubricating oil to reach the boundary section 133. At the boundary section 133, a gap is easily formed between the large part 131 and the small part 132. Therefore, the engine generator 200 can prevent lubricating oil from entering the gap formed between the large part 131 and the small part 132, which could cause sticking or contamination.

[0074] (Third embodiment) The engine generator 300 illustrated in Figure 11 includes a radiator 301. The radiator 301 is an example of an engine cooling unit for cooling the engine 110. In the engine generator 300 configured in this way, the radiator 301 is located further towards the engine 110 than the leg portion 121 of the generator 120, in this case, the leg portion 121 on the engine 110 side. In contrast, the boundary portion 133 is located further away from the engine 110 than the leg portion 121 of the generator 120, in this case, the leg portion 121 on the opposite side of the engine 110. That is, according to the engine generator 300, the boundary portion 133 is formed at a position a certain distance away from the radiator 301.

[0075] According to this configuration example, even if coolant leakage occurs in the radiator 301, the boundary portion 133 is formed at a certain distance from the radiator 301, making it difficult for the coolant to reach the boundary portion 133. Therefore, the engine generator 300 can prevent coolant from entering the gap formed between the large part 131 and the small part 132 at the boundary portion 133, which can cause solidification and contamination.

[0076] (Fourth Embodiment) The engine generator 400 illustrated in Figure 12 includes a fuel tank 401. The fuel tank 401 is an example of a fuel storage section for storing fuel for the engine 110. In the engine generator 400 configured in this way, the fuel tank 401 is located further towards the engine 110 than the leg portion 121 of the generator 120, in this case, the leg portion 121 on the engine 110 side. In contrast, the boundary portion 133 is located further away from the engine 110 than the leg portion 121 of the generator 120, in this case, the leg portion 121 on the opposite side of the engine 110. That is, according to the engine generator 400, the boundary portion 133 is formed at a position a certain distance away from the fuel tank 401.

[0077] According to this configuration example, even if fuel leakage occurs in the fuel tank 401, the boundary portion 133 is formed at a certain distance from the fuel tank 401, making it difficult for the leaked fuel to reach the boundary portion 133. Therefore, the engine generator 400 can prevent fuel from entering the gap formed between the large part 131 and the small part 132 at the boundary portion 133, which can cause solidification and contamination.

[0078] (Fifth embodiment) The engine generator 500 illustrated in Figure 13 is housed inside a rectangular box-shaped cabinet 501 that forms its outer casing. In this case, the engine generator 500 is equipped with a gas turbine engine as the engine 110.

[0079] The cabinet 501 is equipped with a gas turbine engine air intake path 502 for supplying air to the engine 110, which is a gas turbine engine. The gas turbine engine air intake path 502 is an example of a gas turbine engine air intake section. In this case, the gas turbine engine air intake path 502 extends from the generator 120 side toward the engine 110 side in the upper part of the cabinet 501, and is configured to supply air to the engine 110 from the air intake port 502A at its tip.

[0080] Furthermore, the cabinet 501 is equipped with an air intake path 503 for the oil cooler. In this case, the air intake path 503 for the oil cooler extends from the generator 120 side toward the engine 110 side in the upper part of the cabinet 501, and an oil cooler 504 is provided at its tip. The air intake path 503 for the oil cooler is equipped with a fan 505 inside, and by driving this fan 505, air can be supplied to the oil cooler 504. The oil cooler 504 is an example of a lubricating oil cooling unit for cooling the lubricating oil supplied to the engine 110.

[0081] Furthermore, the cabinet 501 is equipped with a generator air supply path 506 for supplying air to the generator 120. The generator air supply path 506 is an example of a generator air supply section. In this case, the generator air supply path 506 extends from the top to the bottom on the side of the cabinet 501 that is on the generator 120 side, and is configured to supply air to the generator 120 from the air intake port 506A at its tip.

[0082] In the engine generator 500 housed within the cabinet 501 configured in this way, the air intake port 502A of the gas turbine engine air intake path 502 is located further towards the engine 110 than the leg portion 121 of the generator 120, in this case, the leg portion 121 on the engine 110 side. Furthermore, the air intake port 502A of the gas turbine engine air intake path 502 is located at a higher position than the engine 110 and the generator 120.

[0083] In contrast, the boundary section 133 is located further away from the engine 110 than the leg section 121 of the generator 120, in this case, the leg section 121 on the opposite side of the engine 110. Furthermore, the boundary section 133 is located at a lower position than both the engine 110 and the generator 120.

[0084] In other words, according to the engine power generator 500, the boundary portion 133 is formed at a position a certain distance away from the air intake port 502A of the gas turbine engine air intake path 502.

[0085] In this configuration example, since the boundary portion 133 is formed at a certain distance from the air intake port 502A of the gas turbine engine air intake path 502, it is difficult for the air supplied from the air intake port 502A of the gas turbine engine air intake path 502 to reach the boundary portion 133. Therefore, it is possible to suppress the air supplied from the air intake port 502A of the gas turbine engine air intake path 502 from affecting the boundary portion 133.

[0086] Furthermore, the oil cooler 504 is located on the leg 121 of the generator 120, and in this case, further towards the engine 110 than the leg 121 on the engine 110 side. Also, the oil cooler 504 is located at a higher position than the engine 110 and the generator 120.

[0087] In contrast, the boundary section 133 is located further away from the engine 110 than the leg section 121 of the generator 120, in this case, the leg section 121 on the opposite side of the engine 110. Furthermore, the boundary section 133 is located at a lower position than both the engine 110 and the generator 120.

[0088] In other words, according to the engine generator 500, the boundary portion 133 is formed at a position a certain distance away from the oil cooler 504.

[0089] According to this configuration example, even if lubricating oil leaks from the oil cooler 504, the boundary portion 133 is formed at a certain distance from the oil cooler 504, making it difficult for the leaked lubricating oil to reach the boundary portion 133. Therefore, it is possible to suppress the effect of lubricating oil leaked from the oil cooler 504 on the boundary portion 133.

[0090] Furthermore, even if air leaks from the oil cooler air intake path 503, the leaked air is less likely to reach the boundary 133, thus preventing the leaked air from affecting the boundary 133.

[0091] Furthermore, the air intake port 506A of the generator air intake path 506 is located at a position offset from directly above the boundary portion 133. In other words, according to the engine power generator 500, the boundary portion 133 is formed at a position a certain distance away from the air intake port 506A of the generator air intake path 506.

[0092] According to this configuration example, it is possible to avoid the air supplied from the air inlet 506A of the generator air supply path 506 directly hitting the boundary portion 133, and to suppress the air supplied from the air inlet 506A of the generator air supply path 506 affecting the boundary portion 133.

[0093] (Sixth Embodiment) In the engine generator 600 illustrated in Figure 14, the terminal block 146 is grounded by an earth wire 601. The legs 143 of the frame 140 are made of metal and are electrically connected to the small parts 132, which are also made of metal. As a result, the small parts 132 are grounded via the legs 143 of the frame 140, the terminal block 146, and the earth wire 601. The engine generator 600 does not have a conductive wire 134 to electrically connect the large parts 131 and the small parts 132.

[0094] This configuration also allows the small part 132, which is a separate component from the large part 131, to be grounded. In this way, by grounding the large part 131 and the small part 132 separately, the entire base section 130, which is composed of multiple parts 131 and 132, can be maintained at ground potential.

[0095] (Other embodiments) It should be noted that this embodiment is not limited to the multiple embodiments described above, and various modifications and extensions can be made without departing from its essence. For example, the engine power generation device may be configured by appropriately selecting and combining the multiple embodiments described above.

[0096] Furthermore, the predetermined direction in this embodiment is not limited to the axial direction S, but can be set to any appropriate direction, such as a direction perpendicular to the axial direction S, a direction intersecting the axial direction S, or a predetermined direction defined independently of the axial direction S.

[0097] Furthermore, the engine-powered generator includes at least an engine, a generator, and a support section, and the engine and generator are supported by the support section. Other components may or may not be included.

[0098] Furthermore, the loading support device is not limited to elevators; any device that can assist in loading the components of an engine power generation system can be used, such as a trolley or similar device.

[0099] Furthermore, this embodiment is suitable when it is desired to install an engine power generator in the basement, but a dedicated access point is not provided on the ground floor. However, this embodiment is not limited to this case, and can be applied to various situations, such as when a dedicated access point is provided on the ground floor, or when the location where the engine power generator is to be installed is not in the basement.

These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
