Abstract
The utility model discloses a theftproof bolt for a transformer, belonging to the technical field of electromechanical equipment. The theftproof bolt for the transformer comprises a bolt (1) provided with a through hole (2), wherein a hollow shell (3) fixed on a transformer base is arranged on the bolt (1), a threaded rod of the bolt (1) is arranged in the hollow shell (3), the front end of the through hole (2) of the bolt (1) is provided with a switch (5), a screw cap (4) matched with the bolt (1) is arranged at the front end of the switch (5), two binding posts of the switch (5) are connected in parallel with a resistor (6), and a twin-core cable (7) respectively connected with the switch (5) and an alarm is arranged in the through hole (2). The theftproof bolt for the transformer is simple in structure, convenient in use, and not only capable of realizing the alarm function, but also capable of effectively delaying the theft time of lawless persons, thereby ensuring the safety of the transformer.
Description
Technical field
The utility model relates to electrical equipment technical field, relates in particular to a kind of transformer anti-theft bolt.
Background technique
At present, transformer generally passes its base by bolt and fixes, and existing bolt is often broken screw rod by the lawless person with saw or other utensil, thereby steal transformer, the case of theft transformer often takes place, thereby causes the huge property loss of people, after transformer is lost power supply department is affected, serious meeting causes and stops doing business, and brings great economic loss to country.In order to prevent the generation of above-mentioned situation, the general method that burglary-resisting installation is installed that adopts, and most alarms all adopt electric wire to twine transformer, after moving, electric wire fracture, transformer inclination and position resolver report to the police, if do not remove bolt earlier but the lawless person does not go to trigger sensor, even after triggering alarm, can in time steal escape like this, so can not delay lawless person's the theft time effectively yet, police can't arrive in the very nick of time, and can not well play antitheft effect.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and not only can realize warning function, and can effectively delay the theft time, thereby can guarantee the transformer anti-theft bolt of transformer safety.
In order to reach above purpose, the technological scheme that the utility model adopted is: this transformer anti-theft bolt, comprise bolt with through hole, described bolt is provided with the hollow casing that is fixed on the transformer base, the screw rod of described bolt is arranged in the described hollow casing, the front end of the through hole of described bolt is provided with switch, the front end of described switch is provided with and the suitable nut of described bolt, two tenminal blocks of described switch are parallel with resistance, are provided with respectively the two core electric wires that are connected with alarm with described switch in the described through hole.
As a kind of improvement, the diameter of described hollow casing is greater than the diameter of described nut.
As a kind of improvement, the diameter of described hollow casing is greater than the diameter of described nut.
The beneficial effects of the utility model are: by being provided with the hollow casing that is fixed on the transformer base on the bolt, the screw rod of bolt is arranged in the hollow casing, thereby avoided the lawless person to utilize the phenomenon of the sawed-off screw rod of instrument, and nut is ensconced in the hollow casing, thereby make lawless person's inconvenience remove nut, prolonged the time of theft; By through hole front end switch is set at bolt, a normally closed switch promptly is set, and with two tenminal blocks of switch resistance in parallel, in through hole, be provided with respectively the electric wire that is connected with alarm with switch, front end at switch is provided with nut then, following situation can occur like this: the two core wire short-circuitings of drawing produce short-circuit condition; When nut was screwed on the bolt, normally closed switch was depressed and forms open circuit, and resistance forms the loop in the middle of two lines, with the circuit state that has a resistance; Nut is twisted the back normally closed switch and is ejected the formation short-circuit condition, just can detect open circuit, short circuit and be connected these several states of resistance by simple circuit like this, thereby can both report to the police when making the interior electric wire of bolt hole be cut off with short circuit, be arranged in the bolt hole owing to electric wire simultaneously, even so destroy screw rod, must cause the electric wire fracture, thereby play antitheft function, make the lawless person be difficult to set about like this, can effectively prolong lawless person's the theft time, thereby police are arrived in the very nick of time, effectively guaranteed the safety of transformer.The utility model is simple in structure, and is easy to use, not only can realize warning function, and can effectively delay lawless person's the theft time, thereby guarantees the safety of transformer.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Make the utility model with reference to accompanying drawing.This transformer anti-theft bolt comprises bolt 1, owing to have through hole 2 in the bolt 1, conveniently wears electric wire.
Be provided with the hollow casing 3 that is fixed on the transformer base on the bolt 1, because the screw rod of bolt 1 is arranged in the hollow casing 3, and the diameter of hollow casing 3 is greater than the diameter of nut 4, can prevent not only that by this structure the lawless person from utilizing the sawed-off screw rod of instrument, and because nut 4 is ensconced in the hollow casing 3, thereby make lawless person's inconvenience remove nut 4, delayed the time of theft, make things convenient for police to arrive in the very nick of time.
Front end at the through hole 2 of bolt 1 is provided with switch 5, switch 5 is the elastic press type normally closed switch, two tenminal blocks at switch 5 are parallel with resistance 6, front end at switch 5 is provided with nut 4, the diameter of nut 4 and bolt 1 suitable 4, in through hole 2, be provided with respectively the two core electric wires 7 that are connected with alarm with switch 5, following several situation can occur by said structure:
When the lawless person backed out nut 4, switch 5 was in channel status, and at this moment, resistance 6 is inoperative, thereby formed the loop with alarm circuit, sent warning message.
When lawless person's dismounting or destruction bolt 1,, form short circuit or turnoff states thereby must destroy electric wire 7, thereby make alarm equipment alarm as sawed-off screw rod.Just can detect open circuit, short circuit and be connected these several states of resistance by simple circuit like this, thereby can both report to the police when making the electric wire of bolt be cut off, for the monitor staff provides reliable guarantee with short circuit.
The utility model is simple in structure, and is easy to use, not only can realize warning function, and can effectively delay lawless person's the theft time, thereby guarantees the safety of transformer.
