Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；
In order to better illustrate this embodiment, the certain components of attached drawing have omission, zoom in or out, and do not represent actual product
Size；
To those skilled in the art, it is to be understood that certain known features and its explanation, which may be omitted, in attached drawing
's.
The technical solution of the utility model is described further with reference to the accompanying drawings and examples.
Embodiment 1
As depicted in figs. 1 and 2, the automatic pump failure termination of pumping detection of the utility model and warning device include 12V DC
Power supply, liquid-level switch F1, relay, alternating current detection module L1, buzzing alarm lamp HD1, water pump M；
Wherein the anode of one end of the normal opened contact F1-1 of liquid-level switch F1 and DC power supply connects, normal opened contact F1-1's
The other end is connected by the coil J1 of relay and the cathode of DC power supply；
One end of the normally opened contact J1-1 of relay and the anode of DC power supply connect, and the other end of normally opened contact J1-1 is logical
The input contact of power supply and the cathode of DC power supply in alternating current detection module L1 is crossed to connect；
One end of the normally opened contact J1-2 of relay and the anode of DC power supply connect, and the other end of normally opened contact J1-2 is logical
Cross alternating current detection module L1 output normally opened contact L1-1 and buzzing alarm lamp HD1 successively with the cathode of DC power supply
Connection；
Alternating current, the power supply N of water pump M are accessed by the normally opened contact J1-3 of circuit breaker Q F and relay in the power supply end L of water pump M
Alternating current is accessed by circuit breaker Q F in end, and the end power supply L of the water pump M or N-terminal either end pass through the alternating current detection module
The centre bore of straight-through current transformer in L1.The power supply N-terminal of water pump M passes through the alternating current and detects mould in the present embodiment
The centre bore of straight-through current transformer in block L1.
The liquid-level switch F1 used in the present embodiment is floating-ball level switch, and installation is suspended in cable shaft side wall, when
Cable Well Water Level rises to water level, and floating ball head is upward, the normal opened contact F1-1 closure of floating-ball level switch F output；As water pump M
Movement draining makes water level decreasing, when floating ball head and then sinks to lower water level, the normally opened dry contact F1- of floating-ball level switch F1 output
1 disconnects.When draining, upper water level closure, lower water level is disconnected.
There is alternating current detection module L1 lower limit holding function and current detection module to act delay feature, using outer
The straight-through current transformer acquisition electric current set.I.e. when the current value of current transformer acquisition is less than alternating current detection module L1
The lower limit value of setting, and already exceed preset alternating current detection module obtain it is electric after can delay time, then alternating current examine
It surveys module L1 and meets operation condition, the normally opened contact L1-1 closure of alternating current detection module L1 output.Wherein alternating current is examined
Certain delay can be had compared to alternating current detection module L1 due to acting to avoid water pump M by surveying module L1 movement delay feature,
And there is of short duration closure in the normally opened contact L1-1 for causing alternating current detection module L1 to export, causes to report by mistake.
Embodiment 2
When cable Well Water Level rises to upper water level and water pump M is because of failure termination of pumping, the present embodiment detection and warning device
Working condition: when cable Well Water Level rises to upper water level, microswitch is acted in floating-ball level switch F1, the normally opened stem grafting of output
Point F1-1 closure, the coil J1 of relay obtain electric, normally opened contact J1-1, J1-2, J1-3 closure of output, make after J1-1 closure
The power supply of alternating current detection module L1, which inputs, to be connected, i.e., alternating current detection module L1 at this time starts to work.Alternating current
When stream detection module L1 collects water pump M main circuit current less than pre-set lower limit action value, it is believed that water pump M stop over
Fortune, the normal opened contact L1-1 closure of alternating current detection module L1 output, buzzer warning indicator light HD1 issue alarm signal.
Since the other end of the normally opened contact J1-1 of relay output passes through the power supply of alternating current detection module L1
It being connect with the cathode of DC power supply, i.e., the power supply of alternating current detection module L1 is latched by relay normally open contact J1-1,
Therefore when water level does not reach the upper water level for needing water pump M to run, alternating current detection module L1 will not work, therefore buzzing report
Alert indicator light HD1 also can not ON operation.
Embodiment 3
When cable Well Water Level rises to upper water level and water pump operates normally, the present embodiment detection and the work of warning device
Situation is substantially same as Example 1, and difference is that alternating current detection module L1 collects water pump M main circuit current and is greater than in advance
When the lower limit action value of setting, it is believed that water pump M is operated normally, therefore the normal opened contact L1-1 of alternating current detection module L1 output
It disconnects, buzzing alarm lamp HD1 also can not ON operation.
The terms describing the positional relationship in the drawings are only for illustration, should not be understood as the limitation to this patent；
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
Exhaustion.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc., should be included in
Within the protection scope of the utility model claims.
