The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0038] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0039] As described in the background technology, existing freight trains generally do not have an electric energy supply, resulting in a lack of energy supply when electronic equipment needs to be installed on the train. The existing solution is to install batteries or add a direct-connected shaft-end generator. Installing batteries requires frequent charging or replacement of batteries, and requires special personnel to operate, which wastes manpower. The direct-connected shaft-end generator is installed at the shaft end of the wheelset, and the vibration acceleration of the wheelset running on the rails is extremely large. The vibration impact directly acts on the generator, which can easily cause damage to the generator or connection failure and detachment. For this reason, the utility model provides the following embodiments.

[0040] Embodiment 1:

[0041] This embodiment provides a power generation device installed on a freight train bogie, such as Figure 1-Figure 7 , Fig.13 and Fig.14 As shown, it includes a generator 100, which is installed on the freight train bogie (i.e., the load-bearing saddle of the bogie) through a mounting frame 200, and the generator is connected to the rotating shaft 300 of the freight train through a flexible transmission member 400.

[0042] The above-mentioned technical features can realize the connection between the generator and the rotating shaft and complete power generation. By reasonably adopting flexible transmission parts, the problem of damage to the connection between the generator and the train axle due to vibration can be solved. It also solves the problem that when the generator is installed on the traditional shaft end, the generator is directly connected to the axle, resulting in large vibration impact, which can easily cause equipment damage, connection failure, and falling off.

[0043] In order to improve the installation reliability of the generator and solve the problem that the shaft end mounted generator cannot install a high-power generator due to space limitations and cannot meet the large load power demand. In one embodiment, Figure 2 and Figure 3 As shown, the mounting frame 200 includes a connecting portion and a mounting portion 203, and the mounting portion 203 is fixedly connected to the generator 100.

[0044] One end of the connecting portion is fixedly connected to the mounting portion 203, and the other end is fixedly connected to the freight train bogie.

[0045] The connecting portion includes a supporting portion 202 and a connecting seat 201 , the connecting seat 201 is fixedly connected to the freight train bogie, and the mounting portion 203 is connected to the connecting seat 201 via the supporting portion 202 .

[0046] The above technical features can achieve that after the vibration source passes through a reasonably designed mounting frame, the vibration acceleration is greatly reduced, eliminating the adverse effects of vibration on the generator.

[0047] In order to facilitate the installation of components between the transmission shaft 300 and the generator (such as transmission parts or devices that facilitate the connection between the transmission parts and the transmission shaft, etc.), in one embodiment, a bearing saddle on the bogie is installed between the mounting portion and the connecting seat. The components such as the mounting frame of the generator are mainly installed on the bearing saddle.

[0048] In order to facilitate the installation of the connection seat and the mounting portion, and to determine the distance between the connection seat and the mounting portion, in one embodiment, Figure 3 As shown, the support portion 202 includes a fastening screw 2021 and a support sleeve 2022 sleeved outside the fastening screw, the support sleeve 2022 is installed between the connecting seat 201 and the mounting portion 203, and the connecting seat 201 is connected to the mounting portion 203 through the fastening screw 2021.

[0049] In order to better connect the generator to the mounting portion and fix the load-bearing saddle 204, in one embodiment, the mounting portion 203 includes a generator connection side 2031 and a support portion connection side 2032, wherein the support portion connection side 2032 is provided with a limit block group for limiting and supporting the load-bearing saddle; further, as Figure 6 and Figure 7 As shown, a limiting block group for limiting and supporting the bearing saddle is provided on one side of the connecting seat 201 close to the mounting portion.

[0050] Furthermore, the limit block group includes an upper limit block 2033 and a lower limit block 2034, and the bearing saddle installation area is formed between the upper limit block and the lower limit block.

[0051] In order to better adapt to the working environment, in one embodiment, the transmission member 400 is a flexible transmission shaft or a telescopic universal joint. The transmission member is used for power transmission between the axle and the generator. Since the generator is fixedly mounted on the bogie, and the axle and the bogie have a slight displacement, the transmission member can be a flexible transmission shaft or a telescopic universal joint, which can offset the displacement between the axle and the bogie. There are connectors at both ends, one end is connected to the generator, and the other end is connected to the axle.

[0052] In order to improve the heat dissipation effect of the generator, in one embodiment, Fig.11and Fig.12 As shown, the generator 100 is provided with heat dissipation fins, and a connection hole 101 is provided on the inner side of the generator, and the connection hole is connected to the transmission member.

[0055] The above-mentioned technical features can realize the connection between the generator and the rotating shaft and complete power generation. By reasonably adopting flexible transmission parts, the problem of damage to the connection between the generator and the train axle due to vibration can be solved. It also solves the problem that when the generator is installed on the traditional shaft end, the generator is directly connected to the axle, resulting in large vibration impact, which can easily cause equipment damage, connection failure, and falling off.

[0056] In order to improve the installation reliability of the generator and solve the problem that the shaft end mounted generator cannot install a high-power generator due to space limitations and cannot meet the large load power demand. In one embodiment, the mounting frame includes a connecting portion and a mounting portion 203, and the mounting portion 203 is fixedly connected to the generator 100;

[0057] One end of the connection part is fixedly connected to the mounting part, and the other end is fixedly connected to the freight train bogie. Further, the connection part includes an upper connection leg 205 and a lower connection leg 206.

[0058] In order to better adapt to the working environment, in one embodiment, the transmission member 400 is a flexible transmission shaft or a telescopic universal joint. The transmission member is used for power transmission between the axle and the generator. Since the generator is fixedly mounted on the bogie, and the axle and the bogie have a slight displacement, the transmission member can be a flexible transmission shaft or a telescopic universal joint, which can offset the displacement between the axle and the bogie. There are connectors at both ends, one end is connected to the generator, and the other end is connected to the axle.

[0059] In order to improve the heat dissipation effect of the generator, in one embodiment, Fig.11 and Fig.12 As shown, the generator 100 is provided with heat dissipation fins, and a connection hole 101 is provided on the inner side of the generator, and the connection hole is connected to the transmission member.
