[0022] When the oil pump station 1 supplies oil to the gear box 3, the output end of the oil inlet pipe 2 is connected to the oil inlet on the gear box 3, and the oil return pipe 4 is connected to the oil outlet on the gear box 3;

[0023] When the oil inlet pipe 2 and the oil return pipe 4 are cleaned, the output end of the oil inlet pipe 2 and the input end of the oil return pipe 4 are connected through the reverse pipe 7 .

[0024] In this embodiment, a filter 5 is provided on the oil return pipe 4 to increase the cleanliness of the oil entering the oil pump station 1. When the oil pump station 1 supplies oil to the gear box 3, the oil is transported to the gear box 3 through the oil pump station 1 to achieve the effects of cooling and lubrication. When cleaning the oil inlet pipe 2 and the oil return pipe 4, the oil can be stopped from being fed into the gear box 3. Instead, the output end of the oil inlet pipe 2 and the input end of the oil return pipe 4 are connected through the reverse pipe 7. Then, the oil inlet pipe 2 and the oil return pipe 4 are knocked to make the attachments in the oil inlet pipe 2 and the oil return pipe 4 fall off, and are filtered through the oil return pipe 4 to the filter 5, and then returned to the oil pump station 1 after filtration. After that, it is only necessary to clean the filter 5 regularly.

[0025] In an exemplary embodiment, a shut-off valve 8 is provided on the oil outlet and the oil inlet of the gearbox 3; when the oil pump station 1 supplies oil to the gearbox 3, the shut-off valve 8 is open, and when the oil inlet pipe 2 and the oil return pipe 4 are cleaned, the shut-off valve 8 is shut off.

[0026] It should be noted that when cleaning the oil inlet pipe 2 and the oil return pipe 4, if a stop valve 8 is provided, there is no need to remove the oil inlet pipe 2 and the oil return pipe 4 from the gear box 3, and only the stop valve 8 needs to be closed.

[0027] Exemplarily, a control module may be connected to the stop valve 8 to control the stop valve 8 .

[0028] In an exemplary embodiment, when the oil inlet pipe 2 and the oil return pipe 4 are cleaned, the output end of the oil inlet pipe 2 is removed from the oil inlet port of the gear box 3 and connected to the reverse pipe 7, and the input end of the oil return pipe 4 is removed from the oil outlet port of the gear box 3 and connected to the reverse pipe 7.

[0029] In this embodiment, if the stop valve 8 is not provided, in order to prevent dirt that falls off from the inside of the oil inlet pipe 2 and the oil return pipe 4 when they are cleaned from entering the gear box 3, it is necessary to remove the oil inlet pipe 2 and the oil return pipe 4 from the gear box 3, and then connect the output end of the oil inlet pipe 2 and the input end of the oil return pipe 4 through a reverse pipe 7.

[0030] In an exemplary embodiment, a control valve is provided on the reverse pipe 7. When the oil pump station 1 supplies oil to the gear box 3, the control valve cuts off the flow. When the oil inlet pipe 2 and the oil return pipe 4 are cleaned, the control valve allows flow.

[0031] It should be noted that a control valve is provided on the reverse pipe 7 to control the connection of the reverse pipe 7.

[0032] For example, if a stop valve 8 is provided, control valves can be provided at both ends of the reverse pipe 7. If a stop valve 8 is not provided, a control valve can be provided at any position of the reverse pipe 7.

[0033] In an exemplary embodiment, a plurality of gear boxes 3 are provided, and the number of the oil inlet pipes 2 and the oil return pipes corresponds to the number of the gear boxes 3 .

[0034] In this embodiment, the oil pump station 1 can supply oil to multiple gear boxes 3 at the same time.

[0035] In an exemplary embodiment, a sampling valve 6 is provided on the oil return pipe 4 at the output end of the filter 5 .

[0036] In this embodiment, the sampling valve 6 is arranged to facilitate oil sampling.

[0037] In an exemplary embodiment, pressure detection sensors are also provided on the return pipes at both ends of the filter 5 .

[0038] In this embodiment, the pressure detection sensor is provided to detect the pressure values ​​at both ends of the filter 5, and to judge whether the filter 5 should be cleaned by comparing the pressure values. When the pressure difference at both ends of the filter 5 is greater than a certain value, it means that the oil return pipe 4 is blocked and the filter 5 needs to be cleaned.

[0039] In an exemplary embodiment, a control module is provided on the control valve, and an output end of the pressure detection sensor is connected to an input end of the control module.

[0040] In this embodiment, the control module may be a controller such as a single chip microcomputer or a PLC to control the actions of each valve and monitor the detection value of the pressure detection sensor.

[0041] Exemplarily, an indicator light may be provided at the output end of the control module, and when the pressure difference across the filter 5 is greater than a preset value, the control indicator light is on.
