Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 2 and 3, for the water level monitoring and over-limit automatic drainage device of the building ponding well disclosed by the utility model, a highest water level line 11, a transition water level line 12 and a lowest water level line 13 are carved on the inner wall of the ponding well 1 from top to bottom in sequence; a first floating ball liquid level switch 21, a third floating ball liquid level switch 23 and a second floating ball liquid level switch 22 are sequentially arranged in the water collecting well 1 from top to bottom in the vertical direction, and the models of the three floating ball liquid level switches are YW-CK-18. The first floating ball liquid level switch 21 is arranged at the highest water level line 11 and used for detecting whether the water level in the well reaches the highest water level line 11, the third floating ball liquid level switch 23 is arranged at the transitional water level line 12 and used for detecting whether the water level in the well drops below the transitional water level line 12, and the second floating ball liquid level switch 22 is arranged at the lowest water level line 13 and used for detecting whether the water level in the well drops below the lowest water level line 13.
A main control box 6 is arranged outside the water collecting well 1, a controller 61 is arranged in the main control box 6, and the controller 61 can be an STC15W series single chip microcomputer. Referring to fig. 3, the first float level switch 21, the third float level switch 23 and the second float level switch 22 are all connected to the controller 61, and may be normally open float level switches.
Referring to fig. 4, the single chip microcomputer includes an IO0 pin, an IO1 pin, and an IO2 pin, the IO0 pin is connected to a +5V power supply through a resistor R1, and the IO0 pin is also grounded through a normally open contact K1 of the first float level switch 21; the IO1 pin is connected with a +5V power supply through a resistor R2, and the IO1 pin is also grounded through a normally open contact K2 of the second float ball liquid level switch 22; the IO2 pin is connected with a +5V power supply through a resistor R3, and the IO2 pin is also grounded through a normally open contact K3 of the third float level switch 23.
The liquid level measurement principle of the three float level switches is the same, and the first float level switch 21 is taken as an example for explanation. When the water level is below the highest water level line 11, the normally open contact K1 of the first float level switch 21 is in an off state, and the IO0 pin of the controller 61 detects a voltage of +5V and inputs a high level; when the water level reaches the highest water level line 11, the normally open contact K1 of the first float level switch 21 is closed, and the IO0 pin of the controller 61 detects a voltage of 0V and inputs a low level. It can be seen that the controller 61 detects a water level condition depending on whether the input to its IO0 pin is high or low.
Referring to fig. 2 and 3, a first water pump 31 connected with a controller 61 is arranged outside the water accumulation well 1, the first water pump 31 is respectively connected with a first water pumping pipeline 41 and a first water drainage pipeline 51, the first water pumping pipeline 41 extends to the lowest water level 13 of the water accumulation well 1, the bottom of the first water pumping pipeline is flush with the lowest water level 13, and the first water drainage pipeline 51 is connected with a ground drainage system.
When the water level in the water accumulation well 1 rises to the highest water level line 11, the normally open contact K1 of the first float level switch 21 is closed, the IO0 pin of the controller 61 inputs a low level, the controller 61 sends an opening control signal to the first water pump 31 according to the detected low level, the first water pump 31 receives the opening control signal to execute an opening action, referring to fig. 2, the first water pump 31 drains the accumulated water in the water accumulation well 1 to the ground drainage system through the first drainage pipeline 51 through the first water pumping pipeline 41.

Since the bottom of the first pumping duct 41 is flush with the lowest water level 13, when the water level drops to the lowest water level 13, the first water pump 31 cannot pump water, so that the flow measured by the flowmeter 7 is zero, the controller 61 controls the first water pump 31 to be closed according to the flow signal of the flowmeter 7, and the pumping and draining are finished.
Referring to fig. 5, when the water level in the sump 1 drops below the lowest water level 13, referring to fig. 4, the normally open contact K2 of the second float level switch 22 is turned off from closed, the IO1 pin of the controller 61 inputs a high level, and sends a turn-off control signal to the first water pump 31, and the first water pump 31 receives the turn-off control signal and performs a turn-off operation.

Therefore, the second water pump 32 connected to the controller 61 may be further provided to assist the first water pump 31 in draining water. The second water pump 32 may be a submersible pump disposed inside the well or a conventional water pump disposed outside the well. Taking the outdoor water pump as an example, two ends of the second water pump 32 are respectively connected with a second water pumping pipeline 42 and a second water drainage pipeline 52, the second water pumping pipeline 42 extends below the transition water level line 12 of the water collection well 1, and the second water drainage pipeline 52 is connected with the ground drainage system.
