The condition that the standby circuit is triggered by mistake can be effectively prevented.
The probe 5 is installed in a non-sealing mode at the suspended end, the installation position of the probe 5 is selected to be installed at the position communicated with a cavity of the device for storing sewage as much as possible, or the probe 5 is directly installed in a sewage cavity, the situation that sewage reaches the installation height of the probe 5 is avoided, but the sewage is not in contact with the probe 5 and cannot form a loop, the sewage height cannot be in contact with the probe 5 no matter how the sewage height changes, the control panel 1011 cannot be started, and the sewage in the device cannot be discharged in time. The connecting end of the probe 5 and the control board 1011 is hermetically installed, and since the connecting section needs to be connected with the control board 1011, an interface connected by a lead is needed, and a metal surface is exposed in the air certainly, so that the connecting part of the probe 5 and the control board 1011 must be ensured to be dry and cannot be in a humid environment, and the situation of false triggering of a loop is easy to occur.

The installation position of the probe 5 is uncertain, only the position is higher than the triggering height of the floating ball, but the distance is not too close as much as possible to prevent error touch, a scheme is that the probe 5 is installed on a control end shell 101 of the floating ball control device 1, because a control plate 1011 is arranged in the shell 101 and has enough sealing environment, one end of the probe 5 connected with the control plate 1011 can be directly installed in the shell 101 and is conveniently connected with the control plate 1011, a clamping groove in the shape of a nut 501 is preset at the joint of the shell 101 and the probe 5, the nut 501 is in sealing interference fit with the clamping groove, meanwhile, the sealing performance in the control cavity can be improved by the clamping groove in interference fit, a corner for liquid flowing is increased by the groove, so that the liquid is less prone to leak into the shell 101, because when a second loop is needed, the liquid level in the device is certainly high, and the sewage in the device can be prevented from leaking into the control cavity, the control board 1011 is destroyed.
The specific implementation scheme is as follows:
when using built-in sewage hoisting device, at first, open the power, the continuous sewage of will living of blow off pipe is gone into in the device, the water level in the device rises, because the impurity in the sewage is more, the floater in the floater controlling means 1 can appear being blocked, lead to the device can not normally be with sewage discharge, but domestic sewage is still in continuing the inflow device, the liquid level height in the device continues to rise, until contacting the free end of probe 5, liquid and the free end contact of two probe 5, sewage connects the free end of two probe 5, make 5 control panels 1011 of probe 1011 connect and form the return circuit, produce the electric current, the electric current transmits for control panel 1011 signal, control panel control motor moves, in time through the sewage discharge of elevator pump 202 in the device.
Because the probe 5 is installed at a high position and the contact time with the sewage is short, the control board 1011 needs to control the motor to be turned off in a delayed manner, and after the sewage is not in contact with the probe 5, the motor continues to work for a period of time until the water level in the device is reduced to a low water level, and the motor stops working. The time for the delayed closing of the motor is determined by the type of the motor in the device and the type of the lifting pump 202, and the sewage in the device is discharged in time by limiting the time for the delayed closing of the motor, so that the control panel 1011 in the sewage soaking device is prevented from burning out the sewage soaking device, and the device is prevented from being scrapped.
The transmission rod of the direct current permanent magnet motor 201 is fixedly connected with an impeller in the lift pump 202 and is also fixedly connected with a chopping blade at the water inlet of the lift pump 202, the chopping blade chops large impurities in sewage entering the lift pump 202, and the influence of the impurities on the impeller in the lift pump 202 is reduced as much as possible. The direct-current permanent magnet motor 201 is selected as the direct-current permanent magnet motor 201, and the direct-current permanent magnet motor 201 can facilitate the control panel 1011 to directly control the action of the motor.
After the control board 1011 in the floating ball control device 1 gives a signal of the motor action, the control board 1011 controls the motor to start with a large torque, the motor just starts to rotate at a faster speed, then slowly reduces the speed, and rotates at a constant speed after the specified speed is reduced, and the initial high-speed rotation can drive the chopping blade to chop the impurities accumulated at the water inlet of the lift pump 202, so that the large impurities are prevented from entering the working chamber of the lift pump 202.
In the motor working process, if the impeller or the shredding blade of lift pump 202 is blocked by impurity or other things in the sewage, direct current permanent magnet machine 201 transfer line is forced to stall, lead to the current increase on direct current permanent magnet machine 201 circuit, control panel 1011 can trigger control panel 1011 through the high potential, control panel 1011 makes the motor reversal, corotation again, this action is repeated many times, discharge impurity by oneself, realize the function of automatically cleaning, reduce the frequency that sewage hoisting device broke down.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
