Abstract

The utility model belongs to the technical field of anti-theft devices and discloses an anti-theft device for a transformer. The anti-theft device for the transformer is characterized by comprising an anti-theft lock and an alarming mechanism, wherein the anti-theft lock comprises a ball-shaped lock body with a notch, a lock pillar crossing the notch, and a lock core controlling the lock pillar to advance and retreat. During use, the notch of the ball-shaped lock body of the anti-theft device for the transformer clamps the joint of the housing of the transformer, and the lock pillar penetrates a screw hole; and the ball-shaped mechanical lock has no effective stress point on the front side so as to be prevented from being damaged by violence.

Description

Anti-theft device for transformer

Technical field

The utility model belongs to the brake pull-rod technical field, relates to anti-theft device for transformer concretely.

Background technology

In the winter time farm slack season, agricultural service transformer is most stops transport, and agricultural service transformer is installed in outside the village more; In few people's process at night, it is stolen to make that transformer is easy to, in order to guard against theft; In non-pouring season, the peasant transports preservation back for preventing stolen generally transformer being pulled down of water conservancy transformer.Install again Deng the irrigation phase temporarily and to reset.Though play the antitheft effect like this, dismounting, cost of transportation height.

Existing on the market now transformer anti-theft means are a lot, adopt modes such as electronic warning or reinforcing to realize mostly.

Adopt electronic warning means mode to have: primary side power alarm, infrared alarm, three-phase imbalance are judged, distribution transforming winds the line warning outward, displacement is reported to the police, vibrations are reported to the police etc.Common advantage is: can in time send alarm signal.But common shortcoming mainly contains 2 points: the one, and got in the time of can't delaying to steal process time or send signal and stolen latter stage.Even cause having sent alarm signal, when treating that administrative staff are on the scene, the offender steals transformer; The 2nd, rate of false alarm is higher, and true time is false during alarm signal, causes administrative staff tired in hurrying back and forth.Time has been grown compelled mostly stopping using.

Adopt the mode of reinforcing antitheft to have: the weldering of transformer base is dead, reinforcing bar covers, mechanical lock pins, distribution transformer is built with brick etc.Can increase offender's theft difficulty, prolong crime time.But administrative staff can't in time find situation.

The utility model content

The technical problem that the utility model solves just provides the anti-theft device for transformer that a kind of good anti-theft effect, operator on duty can in time be found.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: comprise lock and alarm mechanism, said lock comprises the ball-type lock body that has breach, cross the lock of said breach and control the lock core of these lock advance and retreat.

Its additional technical feature is:

Said ball lock body side surface is provided with annular groove, in said groove, is provided with holding wire, and said holding wire is electrically connected with said alarm mechanism;

Said alarm mechanism is provided with the note trigger mechanism;

Be with protective sleeve in the said holding wire outside.

The anti-theft device for transformer that the utility model provides, comparing with prior art has the following advantages: one of which, owing to comprise lock and alarm mechanism; Said lock comprises the ball-type lock body that has breach, cross the lock of said breach and control the lock core of these lock advance and retreat, during use, the breach of the ball-type lock body of this anti-theft device for transformer is stuck in transformer housing junction; Lock passes screw; Mechanical lock is done spheroiding, makes it not have positive effectively stress point, prevents that violence from smashing; Its two because said ball lock body side surface is provided with annular groove, in said groove, be provided with holding wire; Said holding wire is electrically connected with said alarm mechanism, and said alarm mechanism is provided with the note trigger mechanism, can make the offender will inevitably first sawed-off holding wire during sawed-off lockset in attempt; Alarm signal is sent; And after this needing a period of time could sawed-off lockset, and utilize and can guarantee the relevant responsible person scene that arrives in the very nick of time during this period of time, prevent criminal offence even arrest the offender; Its three owing to be with protective sleeve, can prevent to grab the break signal line by claws such as flying birds in the said holding wire outside, cause wrong report.

Description of drawings

Fig. 1 is the structural representation of the utility model anti-theft device for transformer.

The specific embodiment

Further specify below in conjunction with the structure of accompanying drawing the anti-theft device for transformer that the utility model proposed.

As shown in Figure 1, be the structural representation of anti-theft device for transformer.Its structure comprises lock 1 and alarm mechanism 2, and lock 1 comprises ball-type lock body 4, the lock 5 that crosses breach 3 that has breach 3 and controls the lock core 6 of these lock advance and retreat.During use, the breach 3 of the ball-type lock body 4 of this anti-theft device for transformer is stuck in transformer housing junction, lock 5 passes screw, and mechanical lock is done spheroiding, makes it not have positive effectively stress point, prevents that violence from smashing.

The side of ball-type lock body 4 is provided with annular groove 7, in groove 7, is provided with holding wire 8, and holding wire 8 is electrically connected with alarm mechanism 2; Alarm mechanism 2 is provided with note trigger mechanism 9; Can make the offender will inevitably first sawed-off holding wire during sawed-off lockset, alarm signal is sent, and after this need a period of time could sawed-off lockset in attempt; Utilize to guarantee the relevant responsible person scene that arrives in the very nick of time during this period of time, prevent criminal offence even arrest the offender.

Be with protective sleeve 10 in holding wire 8 outsides, can prevent to grab the break signal line, cause wrong report by claws such as flying birds.
