As shown in fig. 1, in the embodiment of the present invention, the distribution valve reversing system further includes an energy supply mechanism 5, and the energy supply mechanism 5 is used for supplying energy to the driving motor 31.

As shown in fig. 1, in the embodiment of the present invention, the energy supply mechanism 5 includes a storage battery 51, and the storage battery 51 is connected to an external power supply and is used for supplying power to the driving motor 31. The external power supply can charge the storage battery 51, and then supply power to the driving motor 31 through the storage battery 51, wherein the external power supply preferably directly receives power from an external power grid, so that the emission and energy consumption of the diesel engine as a power source can be reduced, and the storage battery 51 preferably has a large power density and energy density, so as to meet the requirements of the driving motor 31 on high power and long-time continuous work, and meanwhile, when the material is pumped to the equipment for material waiting, the diesel engine can be stopped, the storage battery 51 drives the distribution valve 2 to continuously swing, thereby not only avoiding the concrete solidification in the hopper 1, but also reducing the running cost of the equipment for material waiting, and through the arrangement of the storage battery 51, the monitoring and the control are convenient.

Specifically, the monitoring mechanism 7 determines the swing angle of the distributing valve 2 by monitoring the rotation angle of the driving motor 31, when the distributing valve swings to the limit position, the control mechanism 6 controls the driving motor 31 to stop, when the driving motor 31 needs to be started, the control mechanism 6 controls the driving motor 31 to be started, the monitoring mechanism 7 monitors electrical parameters such as voltage, current and the like of the driving motor 31 in real time, if the current of the driving motor 31 increases rapidly, the control mechanism 6 controls the storage battery 51 and the power inverter 52 to work according to a preset program so as to adjust the starting voltage, the starting current and the alternating current frequency of the driving motor 31, and therefore the safety of the storage battery 51 and the power grid is protected.
