Abstract
The invention provides a power distribution cabinet with an anti-theft alarm function, which can effectively improve the anti-theft safety performance of the power distribution cabinet. The power distribution cabinet comprises a cabinet body and a cabinet door, wherein a safety lock is arranged on the inner side of the cabinet door, the safety lock comprises two lock tongues, a lock core and a rotating sheet, one end of each lock tongue is movably connected with the rotating sheet through a rivet, the other end of each lock tongue corresponds to a fixing hole on the inner side of the cabinet body, trigger switches are arranged in the fixing holes, and when the cabinet door is closed, the lock tongues can enter into the fixing holes and be in contact with the trigger switches under the rotation of the lock core; an alarm device is arranged on the inner wall of the power distribution cabinet, and the trigger switches are connected with the alarm device through wires; and the alarm device comprises an electric bell, an optocoupler and a rectification circuit and gives out an alarm by virtue of the imbalance of a bridge circuit, and when the cabinet door is damaged, as the lock tongues are positioned in different positions, the contact states between the two lock tongues and the trigger switches are different, the bridge circuit in the alarm device can lose the balance, and an alarm effect is further realized.
Description
Technical field
The present invention relates to power transmission and distribution device field, relate in particular to a kind of power distribution cabinet with anti-theft alarm function.
Background technology
Present manufacturing enterprise and power supply management all need use a large amount of power distribution cabinets or control cabinet etc., in order to lay various control switchs, motor, generator or other control appliances.Comparatively easy because of its use, therefore obtained number of applications at present.But because a lot of power distribution cabinets need be placed in the field, and mostly the equipment for power transmission and distribution that is arranged in the power distribution cabinet be metal materials such as copper, and the emphasis that therefore becomes the lawless person is stolen and stolen object; Existing power distribution cabinet structure is comparatively simple, prized easily, and conventional nurse personnel is also difficult finds, thereby has caused the equipment can not normal power supply, and property loss is comparatively serious, therefore a kind of new device that can improve the anti-theft security property of power distribution cabinet need be provided.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of power distribution cabinet with anti-theft alarm function; No matter be that the power distribution cabinet door is prized; Still the alarm outside line is cut off or short circuit, and alarm all can send alarm signal, thereby effectively improves the anti-theft security performance of power distribution cabinet.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
A kind of power distribution cabinet with anti-theft alarm function; Comprise cabinet and cooperate the cabinet door that is rotationally connected with cabinet, cabinet door inboard is provided with safety lock, and said safety lock comprises two dead bolts, lock core, rotatable lamella; One end of dead bolt and rotatable lamella flexibly connect through rivet; The inboard fixing hole of the other end of dead bolt and cabinet is corresponding, is provided with trigger switch in the fixing hole, when the cabinet door is closed, enters into fixing hole under the rotation of dead bolt at lock core and contacts with trigger switch; The power distribution cabinet inwall is provided with warning device, and trigger switch is connected with warning device through lead.
Further, warning device comprises components and parts such as electric bell, resistance, electric capacity, voltage stabilizing didoe, optocoupler, switch, rectification circuit, and electric bell one end connects electric capacity and resistance; The other end connects controllable silicon; Electric capacity is connected two voltage stabilizing didoes with resistance, controllable silicon connects electric capacity and resistance, and resistance connects optocoupler; Optocoupler connects rectification circuit, and rectification circuit connects resistance and switch.
Further, rectification circuit is made up of two resistance of four voltage stabilizing didoes connections.
Beneficial effect of the present invention is: because power distribution cabinet is provided with two dead bolts that are positioned at diverse location, is not easy to be pried open, thereby plays antitheft effect preferably; Because dead bolt is positioned at diverse location,, certainly will makes two dead bolts different, thereby cause the bridge circuit disequilibrium in the warning device simultaneously, play the warning effect with the contact condition of trigger switch in case the cabinet door is pried open; Cut off or during short circuit, alarm also can be reported to the police because of the bridge circuit disequilibrium when the alarm outside line simultaneously.
Description of drawings
Fig. 1 is a cabinet internal structure sketch map of the present invention.
Fig. 2 is the electrical block diagram of warning device of the present invention.
Embodiment
Combine accompanying drawing that the present invention is done further detailed description at present.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1; A kind of power distribution cabinet of the present invention with anti-theft alarm function; Comprise cabinet 1 and cooperate the cabinet door 2 that is rotationally connected with cabinet, cabinet door 2 inboards are provided with safety lock, and said safety lock comprises two dead bolts 3, lock core 4, rotatable lamella 5; One end of dead bolt 3 and rotatable lamella flexibly connect through rivet; The other end of dead bolt 3 is corresponding with the fixing hole 6 of cabinet inboard, is provided with trigger switch 7 in the fixing hole 6, and dead bolt 3 enters into fixing hole 6 and contacts with trigger switch 7 under the rotation of lock core 4 when cabinet door 2 is closed; The power distribution cabinet inwall is provided with warning device 8, and trigger switch 7 is connected with warning device 8 through lead 9.
As shown in Figure 2, warning device 8 comprises components and parts such as electric bell, resistance, electric capacity, voltage stabilizing didoe, optocoupler, switch, rectification circuit, and electric bell 801 1 ends connect electric capacity 802 and resistance 803; The other end connects controllable silicon 804; Electric capacity 802 is connected two voltage stabilizing didoes 805,806 with resistance 803, controllable silicon 804 connects electric capacity 807 and resistance 808, and resistance 808 connects optocoupler 809; Optocoupler 809 connects rectification circuit 810, and rectification circuit 810 connects resistance 811,812 and switch 813; Rectification circuit 810 connects two resistance 815,816 by four voltage stabilizing didoes 814 and forms.
When the cabinet door was closed, lock core rotation drive rotatable lamella made two dead bolts enter into fixing hole simultaneously and contacts in trigger switch, and this moment, electric bridge kept balance, and warning device is not reported to the police; When the cabinet door was opened, two dead bolts left fixing hole simultaneously, and electric bridge keeps balance, and warning device is not reported to the police; When the cabinet door is destroyed, because dead bolt is positioned at diverse location, therefore certainly will makes two dead bolts different, thereby cause the bridge circuit disequilibrium in the warning device with the contact condition of trigger switch, play the warning effect; Cut off or during short circuit, alarm also can be reported to the police because of the bridge circuit disequilibrium when the alarm outside line simultaneously.
