Abstract
The utility model relates to a pumping unit alarm device in petroleum drilling field, in particular to a brake anti-theft alarm device for a pumping device. The technical scheme includes that an alarm amplification loudspeaker ML is arranged on the outer wall of a distribution box of the pumping unit, two ends M1 and M2 of the alarm amplification loudspeaker ML are connected with an input end of an optical coupler GO, a control electrode of a silicon-controlled rectifier TL is connected with an output end of the optical coupler GO, then serially connected with a resistance R and then connected with a positive pole of the silicon-controlled rectifier TL, the positive pole of the silicon-controlled rectifier TL is in serial connection with a colored string L and then connected to a power supply plug CT, a negative pole of the silicon-controlled rectifier TL is connected with the power supply plug CT which is connected with a distribution box power supply, and a switch of the alarm amplification loudspeaker ML is arranged on the joint of a brake bracket and a pumping unit base. The brake anti-theft alarm device for the pumping device is simple in structure and good in anti-theft effect, when a lawbreaker steals a brake device, and the brake bracket is separated from the pumping unit base, the switch of the alarm amplification loudspeaker ML is touched, and the alarm amplification loudspeaker ML sends out sounds to achieve the effects of frightening and alarming.
Description
Technical field
The utility model relates to a kind of oil pumper warning device in the field of petroleum exploitation, especially relates to a kind of oil pumper brake burglar alarm.
Background technology
In field of petroleum exploitation, the normal phase of oil pumper is in open-air unattended, and brake gear mainly is to be connected on the oil pumping unit base by pin or bolt, is often destroyed or steals by the lawless person, not only causes material damage, also influences oil pumper safety inspection and maintenance.
Summary of the invention
The purpose of the utility model is exactly the defective that exists to prior art, provides a kind of easy for installation and cost of manufacture is low and burglar alarm oil pumper brake timely burglar alarm.
Its technical scheme is: oil pumper panel box outer wall is provided with warning megaphone ML; The M1 of warning megaphone ML, M2 two ends connect the input end of optocoupler GO; The output terminal resistance in series R that is connected optocoupler GO by the control utmost point of controllable silicon TL is connected to controllable silicon TL anode; Controllable silicon TL anode series connection Color lamp string L is connected to attaching plug CT; The negative electrode of controllable silicon TL connects attaching plug CT, and attaching plug CT connects the panel box power supply, and warning megaphone ML switch is arranged on the junction of brake support and oil pumping unit base.
The utlity model has simple in structure, install additional conveniently, good anti-theft effect is when stealing brake gear like the lawless person; When the brake support separates with oil pumping unit base; Touch warning megaphone ML switch, warning megaphone ML sounds, the effect that reaches scaring and report to the police.
Description of drawings
Accompanying drawing is the circuit theory diagrams of present embodiment.
Embodiment
Further describe below in conjunction with accompanying drawing: oil pumper panel box outer wall is provided with warning megaphone ML; The M1 of warning megaphone ML, M2 two ends connect the input end of optocoupler GO; The output terminal resistance in series R that is connected optocoupler GO by the control utmost point of controllable silicon TL is connected to controllable silicon TL anode; Controllable silicon TL anode series connection Color lamp string L is connected to attaching plug CT; The negative electrode of controllable silicon TL connects attaching plug CT, and attaching plug CT connects the panel box power supply, and warning megaphone ML switch 3 is arranged on the junction of brake support and oil pumping unit base.
Principle of work: attaching plug CT connects the panel box power supply; When the brake support separates with oil pumping unit base, touch warning megaphone ML switch 3, warning megaphone ML signal is transferred to optocoupler GO through M1, M2; Make its conducting; Power supply triggers controllable silicon TL conducting through resistance R, optocoupler GO, and Color lamp string L obtains power supply and sparkles, and reaches the prompting purpose.
