Abstract
A blower fan power off acousto-optic indicator comprises a dual power supply, a dual power supply switching cabinet connected with the input end of the dual power supply, a total switch cabinet connected with the output end of the dual power supply switching cabinet, two circuits connected with the output end of the total switch cabinet, separately being a series circuit of a No.1 blower fan control cabinet and a No.1 blower fan and a series circuit of a No.2 blower fan control cabinet and a No.2 blower fan, and a current control output indicating module in series connection between the dual power supply switching cabinet and the total switch cabinet. By using an acousto-optic alarm of the utility model, an operator on duty can know the stalling information of a main blower fan at first time and carry out switching operation on the blower fan in time to thereby guarantee that the stalling interval of the main blower fan does not exceed 10 minutes.
Description
Technical field
The utility model relates to a kind of Acoustooptic indicator, is specially a kind of coal mine blower outage Acoustooptic indicator.
Background technology
The main fan that use in the colliery, all stipulate now must the use dual air blowers and dual power, two blower fans Fans that in use only puts into operation, another is as standby fan.The dual power supply one tunnel that uses is main power supply, and another road is the available power supply, and when main power supply had a power failure suddenly, just the power switching with blower fan arrived the available power supply.The colliery is defined between the normal production period of colliery, no matter is to switch blower fan or Switching power, can not more than ten minute to again moving interval time from the main fan stall, and the namely blowing-out time can not more than ten minute.If having surpassed ten minutes will process by accident.
At present, when main power supply has a power failure suddenly, no matter be to switch blower fan or Switching power, all need personnel hand on duty to move complete operation.During actual production, when certain reason causes the blower fan stall, if operator on duty carelessness can not be learnt in the very first time information of blower fan stall, carry out at once blocked operation, might make blower fan stall interval more than ten minute, then formation accident.
Summary of the invention
For above-mentioned situation, the purpose of this utility model provides a kind of blower fan outage Acoustooptic indicator, can allow the operator on duty learn the information of main fan stall in the very first time, in time blower fan be carried out blocked operation, guarantee that the main fan stall is no more than ten minutes interval time.
The utility model is achieved in the following ways: a kind of blower fan outage Acoustooptic indicator, comprise dual power supply P1 and P2, the dual power switch cabinet 1 that is connected with the dual power supply input end, the master switch cabinet 2 that is connected with dual power switch cabinet 1 output terminal, two circuit that are connected with master switch cabinet 2 output terminals, respectively the sequential circuit of No. 1 air blower control cabinet 3 and No. 1 blower fan 5 and the sequential circuit of No. 2 air blower control cabinets 4 and No. 2 blower fans 6, and the Current Control that is serially connected between dual power switch cabinet 1 and the master switch cabinet 2 is exported indicating module, it is characterized in that described Current Control output indicating module comprises power supply P3, power switch K1, transducer DA, accumulator C, current transformer B, current relay J, fan condition pilot lamp D1 and D2, electric bell RL, current transformer B electricity is connected on the circuit between dual power switch cabinet and the master switch cabinet, current relay J is connected in series with current transformer B, the input end of power supply P3 is connected with power switch K1, power switch K1 and transducer DA, current relay J is connected in series successively, the normally opened contact of current relay J is connected with fan condition pilot lamp D1, fan condition pilot lamp D2 is connected with electric bell RL and is connected with the normally closed contact of current relay J after connecing, and accumulator C is attempted by the output terminal of transducer DA.
Preferably, serial connection test switch K2 between the described current relay J summation current transformer B.
Further, be serially connected with insurance RD between described power switch K1 and the transducer DA.
Blower fan outage Acoustooptic indicator of the present utility model, detect the single-phase current of main fan by current transformer B, control adhesive and the disconnection of current relay J, thus the output indicator signal, in order to make the operator on duty find timely the information of blower fan stall, carry out blocked operation, this indicator is furnished with direct-flow storage battery, when ac power supply, be charge in batteries, when cutting off the power supply because of alternating current, accumulator has been avoided can't exporting indicator signal because AC power has a power failure to circuit supply.
Description of drawings
Fig. 1 is the utility model operating circuit schematic diagram.
Embodiment
As shown in Figure 1, a kind of blower fan outage Acoustooptic indicator, comprise dual power supply P1, P2, the dual power switch cabinet 1 that is connected with the dual power supply input end, the master switch cabinet 2 that is connected with dual power switch cabinet 1 output terminal, two parallelled circuits with master switch cabinet output terminal, it is respectively the sequential circuit of No. 1 air blower control cabinet 3 and No. 1 blower fan 5, the sequential circuit of No. 2 air blower control cabinets 4 and No. 2 blower fans 6, and the Current Control that is serially connected between dual power switch cabinet 1 and the master switch cabinet 2 is exported indicating module, described Current Control output indicating module comprises power supply P3, power switch K1, transducer DA, accumulator C, current transformer B, current relay J, fan condition pilot lamp D1 and D2, electric bell RL, current transformer B electricity is connected on the circuit between dual power switch cabinet and the master switch cabinet, current relay J is connected in series with current transformer B, the input end of power supply P3 is connected with power switch K1, power switch K1 and transducer DA, current relay J is connected in series successively, the normally opened contact of current relay J is connected with fan condition pilot lamp D1, fan condition pilot lamp D2 is connected with electric bell RL and is connected with the normally closed contact of current relay J after connecing, and accumulator C is attempted by the output terminal of transducer DA.Serial connection test switch K2 is serially connected with insurance RD between the described current relay J summation current transformer B between described power switch K1 and the transducer DA.
When main fan normally moves, the electric current that current transformer B obtains is that dual power switch cabinet 1 is to the single-phase current between the master switch cabinet 2, the electric current of a definite value of current transformer B output, current transformer B senses electric current, the normally opened contact of current relay J is closed, by power supply P3 power supply, pilot lamp D1 is luminous.
When having a power failure because of the power supply of main fan or other reason when causing the main fan stall, current transformer B just responds to less than electric current, no current output, current relay J is without electricity, power by power supply P3, the normally closed contact electric bell RL of current relay J sends the sound, controls simultaneously pilot lamp D2 luminous, the effect of sound and light alarm when finishing the main fan stall.
When in operational process, when power supply P3 had a power failure, accumulator C can provide power supply to make the circuit normal operation to circuit, and K2 is test switch, can test the sensitivity of sound and light alarm at the main fan normal operation period.
