[0017] In practical applications, the start and stop of the water pump motor are controlled jointly by the timing control circuit and the water level controller, and green electricity is reasonably used under the premise of ensuring the water supply needs of production and life; the timing control circuit controls the water pump soft starter to start the water pump motor at zero o'clock, controls the water pump soft starter to turn off the water pump motor at eight o'clock, controls the water pump soft starter to start the water pump motor at eleven o'clock, and controls the water pump soft starter to turn off the water pump motor at seventeen o'clock, and reasonably uses green electricity; in any case, when the water level controller detects that the water level of the high-level water reservoir is lower than the lower limit water level, the water pump soft starter controls the water pump motor to start, and when the water level controller detects that the water level of the high-level water reservoir is higher than the upper limit water level, the water pump soft starter controls the water pump motor to stop working, effectively ensuring the water supply needs of production and life; the utility model reasonably uses green electricity and effectively reduces electricity costs under the premise of ensuring the water supply needs of production and life.

[0018] See also Figure 2 The timing circuit includes a first timing switch and a second timing switch. The first timing switch is electrically connected to a first relay KJ1, and the second timing switch is electrically connected to a second relay KJ2. The first output end of the water level controller is connected to the starting end of the water pump soft starter, and the second output end of the water level controller is connected to the stopping end of the water pump soft starter. The first relay KJ1 is connected in parallel with the first output end of the water level controller, and the second relay KJ2 is connected in parallel with the second output end of the water level controller. The first relay KJ1 is connected to the input end of the water level controller.

[0019] See also Figure 2 The first time-controlled switch controls the water pump soft starter through the first relay KJ1 to start the water pump motor, and the second time-controlled switch controls the water pump soft starter through the second relay KJ2 to turn off the water pump motor; that is, when the water level of the high-level water reservoir is lower than the lower limit water level or higher than the upper limit water level, the water level controller automatically controls the water pump soft starter to start and stop, and the time control circuit does not operate; in other cases, if it is in the peak power consumption period (8:00 to 11:00 and 17:00 to midnight), the first time-controlled switch controls the first relay KJ1 to disconnect, and the second time-controlled switch controls the second relay KJ2 to close, and then the water pump motor is controlled to be turned off through the water pump soft starter; if it is in the valley power consumption period, the first time-controlled switch controls the first relay KJ1 to close, and the second time-controlled switch controls the second relay KJ2 to disconnect, and then the water pump motor is controlled to be turned on through the water pump soft starter.

[0020] The pump motor has a power of 180 kW. According to previous statistics, the pumping hours average 16 hours per day, consuming 2,880 kWh of electricity. In fully automatic mode, where the water level controller automatically starts and stops the pump's soft starter and the timer circuit is inactive, the electricity cost is 0.49 yuan per kWh. After improvements, the pump runs only for 8 hours per day during normal hours, at 0.247 yuan per kWh, and 8 hours during off-peak hours, at 0.062 yuan per kWh. This avoids peak electricity consumption for 8 hours, effectively utilizing renewable energy. This results in a total daily electricity savings of 940 yuan, effectively reducing electricity costs.
