Description
Technical field:
The utility model relates to OFME alarm technique, especially safety of pumping unit voice warning device.
Background technology:
Oil pumper electric shock accidents, mechanical wounding happens occasionally, and oil pumper is all labeled with safety signs now, and effect is not clearly.Safety of pumping unit voice warning device installs phonetic warning system module on oil pumper power distribution cabinet, and module is divided into two parts.One is oil pumper cupboard leakage-current alarm, and another part is by inputting security warning voice in advance in voice module.Can when start and stop oil pumper, voice message security warning language, safety standard operates, thus improves the device of safety factor, prevents from getting an electric shock and mechanical wounding, has good application prospect and promotional value.
Summary of the invention:
The purpose of this utility model is to provide a kind of security protection, has the safety of pumping unit voice warning device preventing mechanical accident and electric shock accidents, which overcome the shortcoming of current technology, the purpose of this utility model realizes like this, it comprises voice module and flip flop equipment, power supply change-over device, power supply change-over device is arranged in oil pumping machine control cabinet, can convert the 36V AC power of control circuit to 12V dc source.
Described flip flop equipment is provided with leakage trigger device circuit, microswitch triggering line, door status switch triggering line, leakage trigger device circuit is provided with light resistor in airtight box, neon tube, light resistor connects light-inductive switch, and the resistance of neon tube one series connection resistance 500K-1M connects other end over the ground and is connected on power distribution cabinet housing, and light-inductive switch connects 12V dc source.
Described microswitch triggering line is connected on switch board stopping and start button.
Described door status switch triggering line is connected on switch board door.
Described voice module connects 12V dc source, connects various flip flop equipment, loudspeaker; Store multistage voice wave band in voice module, by different triggering modes, send corresponding secure voice, point out correct method of operating.
Application process of the present utility model is: alarming device be by; Leakage trigger device circuit, microswitch triggering line, door status switch triggering line, the composition such as voice module and control circuit.Leakage trigger circuit is provided with light resistor in airtight box, neon tube, light resistor connects light-inductive switch, and the resistance of neon tube one series connection resistance 500K-1M connects other end over the ground and is connected on power distribution cabinet housing, and light-inductive switch connects 12V dc source; When switch board body leakage, neon tube luminous, drives the action of light-inductive on-off controller, and voice module circuit is closed drives alarm prompting leak current fault; Control circuit connects control transformer 36V AC power on power distribution cabinet, by converter change into voice module can 12V dc source, open at power distribution cabinet, close on button and connect two fine motion gauge taps, a door status switch controller, be used for triggering corresponding voice, control the voice status of alarming device; Voice module connects power supply respectively, triggering line and loudspeaker.In voice module, typing has each section of voice, by different triggering modes, sends corresponding voice.Triggering mode can be set to, and the closed Yi ﹑ closed circulation Bo Fang ﹑ disconnection broadcasting Yi ﹑ that play disconnects loop play, when multiple electric shock is eligible, only detects forward contact; In time opening switch board door, " start and stop oil pumper please wear insulating glove and prevent from getting an electric shock the closed prompting of door magnetic induction switch." when pressing stop button, microswitch triggering voice module, voice message " please be cut off the electricity supply, tension brake ", " ascending a height, Buckle Up, and standard operation is taken care ".After cutting off oil pumper power supply, voice stop.The voice activated device when power turn-on, voice message " notes cleaning oil pumper peripheral obstacle ", points for attention such as " power transmissions of leaning to one side "; During voice message after pressing start button " whether inspection oil pump running is normal " pass control gate, voice message " is tidied up work apparatus, is taken care " device afterwards and enters resting state.
The utility model structure is simple; There is the function preventing from getting an electric shock or mechanical accident occurs, ensure that safety in production; Improve production efficiency.
Accompanying drawing illustrates:
Fig. 1 is the circuit diagram of safety of pumping unit voice warning device.
