Abstract
The utility model belongs to the field of warning equipment and particularly relates to a failure warning device of a water cooling system for controlling warning by detecting the water flow. The utility model aims at providing the failure warning device of the water cooling system for judging that whether the water cooling equipment works or not and controlling the warning by detecting the water flow. The failure warning device of the water cooling system comprises an induction contact I and has the structural key points that the induction contact I, an induction contact II, a triode I and a triode II are combined into a control circuit to control a relay to act, and a normally-closed switch of the relay is connected with a buzzer in series and then is connected with the two ends of a DC power supply.
Description
Technical field:
The utility model belongs to the alarm equipment field, relates in particular to a kind ofly to control the water-cooling system accident warning device of whether reporting to the police by detecting having or not of current.
Background technology:
Water cooling equipment is applied in all trades and professions, and it plays enormous function to our life and production, but what warning facility existing water cooling equipment does not almost have; Because it is inner that water circulating pump mostly is placed on machinery, water pump damages or forgets switch power supply, does not have recirculated water to be difficult for being found.
Summary of the invention:
The purpose of this utility model is to provide a kind of and judges whether water cooling equipment works, by detecting the water-cooling system accident warning device that current control is reported to the police.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises sense contact I, its structural feature is that sense contact I, sense contact II, triode I and triode II are combined into control circuit and come pilot relay action, is connected with the direct supply two ends behind the relay normally closed switch series connection hummer.
The beneficial effects of the utility model:
Make through the current behind the water cooling equipment flow through sense contact I and sense contact II, can make things convenient for the maintenance of water cooling equipment by detecting having or not to control and whether reporting to the police of current like this.
Description of drawings:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment:
The utility model comprises sense contact I A, and sense contact I A, sense contact IIB, triode I Q1 and triode II Q2 are combined into control circuit pilot relay N1 action, is connected with the direct supply two ends behind the relay N1 normally closed switch series connection hummer N2.
When current made sense contact I A and sense contact II B UNICOM, DC voltage was added on the triode I Q1 base stage and makes it conducting, triode II Q2 conducting thereupon, and relay N1 control end powers up relay N1 normally closed switch is opened, and hummer N2 does not cry; When current disappeared, triode I Q1 base stage lost bias voltage and ends, and triode II Q2 ends thereupon, relay N1 control end dead electricity, and the normally closed switch closure, hummer N2 pipes.
Below in conjunction with a description of drawings course of action of the present utility model:
Make through the current behind the water cooling equipment flow through sense contact I and sense contact II, when no current were flowed through sense contact I and sense contact II, hummer N2 piped.
