Description
Technical field
The utility model relates to cable technology field.
Background technology
Fast development along with national economy, urban infrastructure constantly perfect, spreading all over various places, town and country electric power, agricultural cable, highway, railway, mine etc. progressively lays with cable and puts in place, the cabling reconstructing of pole line increases gradually simultaneously, for the people's productive life, bring great convenience, promoted the development that national economy is faster and better.
Along with cable line length constantly increases, the stolen phenomenon of cable is increasing, and stolen cable is mainly copper core cable, and in new cabling the proportion of copper core cable also in continuous increase.Rise along with metal prices such as copper, the cable line pilferage activity of laying or stopping transport is becoming increasingly rampant, according to statistics during 2011 to 2013, there is altogether cable and lose event 12 times in city, Handan City, cause the millions of units of direct economic loss, nationwide cable line is because of nearly hundred million yuan of the economic losses that cause of theft.Cable is stolen causes huge economic loss, and it again lays and waste time and energy, and causes large area, has a power failure on a large scale, gives to produce and life is made troubles.
Chinese patent 2009101624887 discloses a kind of antitheft cable, stolen for preventing cable, but it needs tailor-made cable, can not be for the cable theft-prevention having laid, high cost.
Utility model content
The utility model provides a kind of cable antitheft device, can be arranged on the optional position of cable, has realized the whole process protection of cable, effectively made up nurse blind area, saved a large amount of manpowers, and reported to the police in time, accuracy rate is high, has greatly improved work efficiency and management level; Simple in structure, easy for installation, without tailor-made cable, cost is low.
Technical solution adopted in the utility model is:
A cable antitheft device, it comprises transmission line and is connected on alarm, power supply and the power switch on transmission line, and one end of transmission line is connected with the armouring of cable, and the other end of transmission line is electrically connected to one or more cable core.
Preferably, transmission line is electrically connected to metal core or the copper shield of cable core.
Preferably, power supply is energy storage type power supply.
Further preferred, also comprise electric-quantity display device, electric-quantity display device is connected to both ends of power.
The beneficial effect that adopts technique scheme to produce is:
1, cable antitheft device of the present utility model can be arranged on the optional position of cable, has realized the whole process protection of cable, has effectively made up nurse blind area, saves a large amount of manpowers, and reports to the police in time, and accuracy rate is high, has greatly improved work efficiency and management level.
2, cable antitheft device of the present utility model is simple in structure, easy for installation, and without tailor-made cable, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1, alarm; 2, transmission line; 3, armouring; 4, power supply; 5, power switch; 6, electric-quantity display device, 7, cable core.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A cable antitheft device, as Fig. 1, it comprises transmission line 2 and is connected on alarm 1, power supply 4 and the power switch 5 on transmission line 2, and one end of transmission line 2 is connected with the armouring of cable 3, and the other end of transmission line 2 is electrically connected to one or more cable core 7.
Power supply is all the time in on-state, once conducting between armouring 3 and cable core 7 has electric current by sending warning in alarm 1, reports to the police in time fast.
Another technical scheme of the present utility model is that transmission line 2 is electrically connected to metal core or the copper shield of cable core 7.
For the ease of carrying, power supply 4 adopts energy storage type power supply, is convenient to install everywhere.
Further, cable antitheft device of the present utility model also comprises electric-quantity display device 6, and electric-quantity display device 6 is connected to power supply 4 two ends.Because antitheft device is treated alert state, do not need power consumption, adopt electric-quantity display device to show electric weight, electric weight charges when not enough in time, guarantees antitheft device energy and alarm.
Thief-proof principle: when cable is cut, the blade of cutting makes cable armouring 3 be connected with metal core or the copper shield of cable core 7, makes whole current return conducting, alarm 1 work, sounds the alarm.
In application, formulate cable nurse flow process, once there be people to start to cut cable, alarm 1 gives the alarm, and nurse personnel, on one side to project director's report, search stolen point Yi Bian send someone to step up to make an inspection tour, by responsible official, dial 110 warnings, offender is arrested, guarantee the safety of cable.
Cable antitheft device can, in the cable work of newly setting up, also can add cable antitheft device in the cable line having set up.
On probation by a plurality of projects, cable antitheft device has not only reached saving manpower, and the object of increasing work efficiency, and further improved the management level of new cabling cuts cable to change engineering efficiently to carry out, and puts into operation on time.
According to the principle of work of cable antitheft device, antitheft device of the present utility model can also play and use safe voltage, check cable and search the effect of cable line phase sequence, and can judge triple cable disconnection fault, phase fault and earth fault.
