Embodiment one:

when the device is used, the time of an external timer can be set according to the sunrise and sunset time of the day, namely, when the set sunrise and sunset time is reached, the external timer can give a signal to the micro servo motor 148, the micro servo motor 148 is started to rotate positively to realize the opening of the valve, and when the set sunset time is reached, the external timer can give a signal to the micro servo motor 148, the micro servo motor 148 is started to rotate reversely to realize the closing of the valve, meanwhile, the opening of the valve plate 143, namely, the distance between the top end of the valve plate 143 and the top end of the inner cavity of the valve slot 142 corresponds to the sunshine time, namely, the distance time between sunrise and sunset is different, and the corresponding opening of the valve plate 143 is different.

And when the valve plate 143 is opened, the flow rate of the hydraulic oil pumped into the flow tube 131 tends to be in a constant state, at this time, the pressure and the flow rate of the hydraulic oil flowing into the flow tube 131 need to be ensured to be in a constant value, because the space inside the flow tube 131 is constant, i.e. when the piston plate 132 is displaced to the forefront end, the rear end of the piston plate 132 and the rear end space of the inner cavity of the flow tube 131 are in a constant state, i.e. when the hydraulic oil flowing into the flow tube 131 moves to the limit position in the piston plate 132, the hydraulic oil flowing into the flow tube 131 is in a constant state, i.e. the flow rate of the hydraulic oil flowing into the flow tube 131 is a fixed value in one day, i.e. the same space volume as the corresponding flow tube 131, and the duration of the hydraulic oil flowing into is variable, which can be calculated by the interval time of sunrise and sunset.
