[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0029] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, rotated 90 degrees or in other orientations, and the spatially relative descriptions used herein are interpreted accordingly.

[0030] like Figures 1 to 7 As shown, the fuel cell power generation device of this embodiment includes: a base assembly 10, a turntable assembly 20 and a fuel cell mounting seat assembly 30. The turntable assembly 20 includes a driving structure 21 and a turntable structure 22 matched with the driving structure 21, the driving structure 21 is fixed on the base assembly 10, and the turntable structure 22 is rotatably mounted on the base assembly 10. The fuel cell mounting seat assembly 30 is mounted on the turntable structure 22 for mounting the fuel cell assembly 60.

[0031] When using the technical solution of this embodiment, the fuel cell mounting seat assembly 30 to be installed is first turned to a lower and easy-to-install position by the turntable assembly 20, and the fuel cell assembly 60 is installed on the fuel cell mounting seat assembly 30, and then the fuel cell assembly 60 is moved to a higher position by rotating the turntable assembly 20. Such installation is efficient and fast, and the installation and transportation are relatively safe. The technical solution of this embodiment effectively solves the problem of the difficulty of stacking when the fuel cell stack is high in the prior art.

[0032] like Figures 2 to 4As shown, in the technical solution of this embodiment, the turntable structure 22 includes an active turntable 221 and a driven turntable 222. The active turntable 221 is rotatably mounted on the base assembly 10, and the driven turntable 222 is rotatably mounted on the base assembly 10. The rotating shaft of the active turntable 221 is connected to the driving structure 21, the wheel of the active turntable 221 is rotatably connected to the fuel cell mounting seat assembly 30, and the wheel of the driven turntable 222 is rotatably connected to the fuel cell mounting seat assembly 30. The active turntable 221 provides power for the movement of the fuel cell mounting seat assembly 30, and the movement of the driven turntable 222 and the fuel cell mounting seat assembly 30 is more stable, that is, the fuel cell mounting seat assembly 30 is not easily disturbed by external forces. It should be noted that when the fuel cell mounting seat assembly 30 is moving, the up and down position and direction of the fuel cell mounting seat assembly 30 will never change, such as tilting or inversion. As shown in FIG. Figure 7 As shown in the schematic diagram, the fuel cell mounting seat assembly 30 will not swing easily due to the joint restraint of the active rotating disk 221 and the driven rotating disk 222 .

[0033] like Figure 4 As shown, in the technical solution of this embodiment, the driving structure 21 includes a driving motor 211, a reducer 212 and a first bevel gear 213, the turntable structure 22 includes a second bevel gear 223, the driving motor 211 and the reducer 212 are both fixed on the base assembly 10, the output shaft of the driving motor 211 is connected to the reducer 212 through a gear, the first bevel gear 213 is arranged at the output end of the reducer 212, the second bevel gear 223 is arranged on the output shaft of the active turntable 221, and the first bevel gear 213 is meshed with the second bevel gear 223. The setting of the reducer 212 plays a role in reducing the rotation speed and increasing the output torque. When the fuel cell mounting seat assembly of this embodiment moves, the speed does not need to be high, and the torque requirement is high. Increasing the torque enables the purpose of this embodiment to be achieved by a smaller motor.

[0034] like Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the driving rotary disc 221 and the driven rotary disc 222 are located on both sides of the fuel cell mounting seat assembly 30. The above structure is compact and has a good restraining effect on the fuel cell mounting seat assembly 30.

[0035] like Figures 2 to 6As shown, in the technical solution of this embodiment, the active turntable 221 includes a driving shaft arranged on the wheel disc of the active turntable 221, the driven turntable 222 includes a driven shaft arranged on the wheel disc of the driven turntable 222, and the fuel cell mounting seat assembly 30 is provided with a driving shaft mounting hole and a driven shaft mounting hole, the driving shaft is rotatably mounted in the driving shaft mounting hole, and the driven shaft is rotatably mounted in the driven shaft mounting hole. When the driving shaft is matched with the fuel cell mounting seat assembly 30 alone, the fuel cell mounting seat assembly 30 can swing around the driving shaft, and when the driving shaft and the driven shaft are matched with the fuel cell mounting seat assembly 30 at the same time, the fuel cell mounting seat assembly 30 is not easy to swing, so that the fuel cell mounting seat assembly 30 is not easy to swing when it is installed on the fuel cell power generation device. It should be noted that the swing of the fuel cell can easily cause the center of gravity of the fuel cell power generation device to shift, which is dangerous. The driving shaft, the driven shaft, the central axis of the active turntable 221 and the central axis of the driven turntable 222 are all parallel. The central axis of the driving rotating disk 221 and the central axis of the driven rotating disk 222 may have different heights.

[0036] like Figure 5 and Figure 6 As shown, in the technical solution of this embodiment, the drive shaft mounting hole is set at the top of the fuel cell mounting seat assembly 30, and the driven shaft mounting hole is set at the bottom of the fuel cell mounting seat assembly 30. Such a structure has a better constraint on the fuel cell mounting seat assembly 30, and the torque generated by the drive shaft and the driven shaft on the fuel cell mounting seat assembly 30 is relatively large, and the fuel cell mounting seat assembly 30 is not prone to swing.

[0037] like Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the fuel cell mounting seat assembly 30 includes a plurality of fuel cell mounting seat assemblies 30, and the plurality of fuel cell mounting seat assemblies 30 are installed on the turntable assembly 20 at intervals. Such a structure realizes full utilization of the space of the fuel cell mounting seat assembly 30. It should be noted that the central angles corresponding to adjacent fuel cell mounting seat assemblies 30 of the plurality of fuel cell mounting seat assemblies 30 are the same, that is, if six fuel cell mounting seat assemblies 30 are installed, the central angles corresponding to adjacent fuel cell mounting seat assemblies 30 are sixty degrees. In this way, the force on the entire turntable is relatively balanced, and the turntable and the central axis are connected by a plurality of spokes, which can effectively reduce the mass of the active turntable 221 and the driven turntable 222. The active turntable 221 may include a plurality of turntables of different diameters, the central axes of the plurality of turntables coincide with each other, and a plurality of fuel cell mounting seat assemblies 30 are arranged on each turntable.

[0038] like Figure 5 and Figure 6As shown, in the technical solution of this embodiment, the fuel cell mounting seat assembly 30 includes a fuel cell mounting seat structure 31 and a counterweight structure 32, and the counterweight structure 32 is installed on the fuel cell mounting seat structure 31. The setting of the counterweight structure 32 can change the center of gravity height of the fuel cell mounting seat assembly 30 on the one hand. In addition, the center of gravity of the fuel cell has a certain uncertainty. The center of gravity of the combination of the fuel cell mounting seat assembly 30 and the fuel cell can be adjusted to a suitable position by adjusting the counterweight structure 32. It should be noted that the connecting line of the drive shaft mounting hole and the driven shaft mounting hole passes through the center of gravity of the combination.

[0039] like Figure 5 and Figure 6 As shown, in the technical solution of this embodiment, the bottom of the fuel cell mounting seat structure 31 has a counterweight structure mounting portion, and the counterweight structure 32 is detachably mounted on the counterweight structure mounting portion. The counterweight structure 32 is mounted at the bottom of the fuel cell mounting seat structure 31, which has a better effect on the downward shift of the center of gravity. In addition, the counterweight structure 32 of the above structure is convenient to disassemble and assemble. For example, the counterweight structure 32 includes a plurality of metal blocks, and the metal blocks are mounted on the counterweight structure mounting portion by bolts. According to the center of gravity of the fuel cell, the installation of the plurality of metal blocks is adjusted. For example, if the center of gravity of the fuel cell is to the left, then one or more metal blocks can be installed on the counterweight structure mounting portion on the left side than on the counterweight structure mounting portion on the right side.

[0040] like Figures 1 to 3 As shown, according to the technical solution of the present application, a fuel cell power generation device is also provided, the fuel cell power generation device includes a fuel cell installation mechanism, and the fuel cell installation mechanism is the above-mentioned fuel cell installation mechanism. The base assembly 10 includes a fuel cell installation area 100, an electrical installation area 200 and an energy storage area 300, and the fuel cell power generation device also includes a power distribution cabinet assembly 40 and an energy storage assembly 50, the turntable assembly 20 is located in the fuel cell installation area 100, the power distribution cabinet assembly 40 is located in the electrical installation area 200, and the energy storage assembly 50 is located in the energy storage area 300. The fuel cell power generation device of this embodiment has an energy storage function and a function of being connected to an external power grid. This further expands the versatility of the fuel cell power generation device.

[0041] The fuel cell assembly 60 is detachably mounted on the fuel cell mounting seat assembly 30 by fasteners. The fuel cell mounting seat assembly 30 is a frame structure, which includes: a base and an upper frame, the base is composed of a plurality of square steels welded horizontally and vertically, the upper frame includes vertically arranged square steels and an arc-shaped dome, the bottom of the vertically arranged square steel is connected to the base, the top of the vertically arranged square steel is connected to the arc-shaped dome, and the arc-shaped dome is rotatably connected to the turntable structure 22. The fuel cell assembly 60 is mounted on the upper part of the base, and the metal block is mounted on the lower part of the base.
