  Specifically, the storage panel 700 is closer to the X1 direction than the generator 400 and between the operation panel 500 and the control panel 602 (Y2 direction side from the operation panel 500 and Y1 from the control panel 602). (Direction side).

  FIG. 3 is a view seen from the direction of arrow III in FIG. 2, and shows only the common platform 200, the storage panel 700, the air cleaner 310, the operation panel 500 and the control panel 602. FIG. 4 is a perspective view showing a support base 800 that supports the storage board 700. In FIG. 4, the storage board 700 is indicated by a virtual line.

  As shown in FIGS. 3 and 4, the storage board 700 is a substantially rectangular parallelepiped box, and is supported on the common platform 200 by a support frame 800.

  As shown in FIG. 4, the support frame 800 includes four support members 801, 801,... Of the column members 801, 801,..., The upper ends of the column members 801, 801 adjacent in the X direction are connected by a bridging member 802, respectively. Moreover, the upper ends of the column members 801, 801 adjacent in the Y direction among the column members 801, 801,... Are connected by a bridging member 803, respectively. The support frame 800 is configured by integrally connecting the support member 801 and the bridging members 802 and 803 by bolting.

  A storage board 700 is placed on each of the bridging members 802 and 803, and a lower panel 701 (see FIGS. 7 and 8) of the storage board 700 is bolted to the bridging members 803 and 803. Accordingly, the storage board 700 is disposed at an upper position at a predetermined distance from the upper surface of the common platform 200 (with a distance corresponding to the height dimension of the support member 801). The installation position of the storage board 700 is closer to the X1 direction than the installation position of the generator 400, and has a relatively short distance (for example, about several tens of mm) in the X direction with respect to the generator 400. It is a position to face. That is, the storage board 700 faces the generator 400 in proximity to the generator 400 at a position opposite to the position where the engine 300 is disposed.

  The X1 direction side edge of the column member 801 located on the X1 direction side among the column members 801 and 801 adjacent in the X direction, and the X2 direction side edge of the column member 801 located on the X2 direction side Is approximately equal to the length dimension of the storage board 700 in the X direction. Therefore, the X1 direction end edge of the bridging member 803 located on the X1 direction side among the bridging members 803 and 803 extending along the Y direction and the X2 direction of the bridging member 803 located on the X2 direction side. The distance from the side edge also substantially matches the length dimension of the storage board 700 in the X direction. In addition, the length dimension (the length dimension in the Y direction) of each of the bridging members 803 and 803 extending along the Y direction substantially matches the length dimension in the Y direction of the storage board 700. Therefore, these bridging members 803 and 803 are arranged along the outer edge of the lower surface panel 701 of the storage board 700 to support the storage board 700. Thereby, the storage board 700 is stably supported.

  Next, the storage board 700 will be described. FIG. 5 is a front view of the storage board 700. FIG. 6 is a plan view of the storage board 700. FIG. 7 is a bottom view of the storage board 700. FIG. 8 is a front view showing the inside of the storage board 700. 9 is a cross-sectional view of the storage board 700 at a position corresponding to the line IX-IX in FIG. 10 is a cross-sectional view of the storage board 700 at a position corresponding to line XX in FIG.

  As shown in these drawings, the storage board 700 is formed of a substantially rectangular parallelepiped box, and the vertical direction (Z direction) is slightly closer to the Y1 direction side than the central position in the left and right direction (Y direction). A partition plate 702 is provided (see FIG. 10). Thus, the internal space of the storage board 700 is partitioned into a right space 700A located on the Y2 direction side and a left space 700B located on the Y1 direction side (see FIGS. 8 and 10).

The openings 704a, 704a,... Are also formed at 12 locations (2 rows in the X direction and 6 rows in the Y direction as shown in FIG. 6). The reason why a plurality of power output lines 402, 403, 404 for each phase are provided in this way (four in each embodiment in this embodiment) is because the output current value is relatively high. For this reason, the number of power output lines 402, 403, and 404 for each phase is not limited to that described above. When the number of power output lines 402, 403, 404 for each phase is different from the above, the number of openings 704a, 704a,...

The technique for maintaining the voltage constant is not limited to this.

  The power output terminal blocks 721 and 722 are provided at two locations. Specifically, electric power is supplied to the Y1 direction side (left side in FIG. 8) and the lower side (Z2 direction side) of the automatic voltage regulator 710 on the rear panel 703 of the storage panel 700. Output terminal blocks 721 and 722 are provided. These power output terminal blocks 721 and 722 are connected to output lines for supplying a part of the power generated by the power generator 400 to a predetermined device (for example, auxiliary machinery of the engine 300). Reference numerals 741 and 742 in the figure denote wiring ducts for wiring these output lines.

  In addition, in the upper panel 704 of the storage board 700, an opening 704b for drawing a control line 711 connected to the automatic voltage regulator 710 into the left space 700B is formed in a region located above the left space 700B. (See FIG. 6). Further, in the lower panel 701 of the storage board 700, openings 701b and 701b for drawing out the output lines connected to the power output terminal blocks 721 and 722 from the left space 700B are provided in the region located below the left space 700B. Is formed (see FIG. 7).

  Further, as shown in FIG. 5, two doors 751 and 752 are provided on the front surface of the storage board 700.

Thereby, each of the right space 700A and the left space 700B can be opened and closed individually. The doors 751 and 752 are provided with handles 751a and 752a.

  As described above, since the automatic voltage regulator 710 and the power output terminal blocks 721 and 722 are housed in the common housing panel 700, the power output lines 402, 403, and 404 extending from the generator 400 are stored in the housing panel. 700 (see FIG. 3). Then, the electric power passed through the power output lines 402, 403, and 404 drawn into the storage board 700 is adjusted in voltage by the automatic voltage regulator 710 and supplied toward the load.

  Since the power output lines 402, 403, and 404 are arranged as described above, the exposed length of the power output lines 402, 403, and 404 extending from the generator 400 is between the generator 400 and the storage panel 700. The length of the power output lines 402, 403, and 404 can be set short.
