Abstract
The utility model discloses an anti-electric shock preliminary warning watch, comprising a watch body, wherein the chamber between the watch surface in the watch body and the surface glass of the watch is provided with a watch inner shadow ring of antenna function, the watch inner shadow ring is connected with an anti-electric shock preliminary warning circuit in the watch body via an antenna connecting sheet. The anti-electric shock preliminary warning watch has reasonable structure, and good anti-electric shock preliminary warning effect, and the watch inner shadow ring is a receiving antenna of the anti-electric shock preliminary warning circuit and the inner shadow ring of the watch, thereby improving safety and reliability. The anti-electric shock preliminary warning watch has timing and near-electric warning functions.
Description
Technical field:
The utility model relates to a kind of wrist-watch, is a kind of protection against electric shock alarm watch.
Background technology:
The receiving antenna of existing product generally is that the clear glass body internal surface at Watch glass has a conductive membrane layer as receiving antenna, as Chinese patent 96223610.1, the shortcoming of this structure is if the workman breaks Watch glass in construction, make conductive membrane layer not circlewise or the wrist-watch watch glass is whole bumps, alarm will lose report to the police or alarm distance less than safe distance, thereby lose the pre-alarm function.
The alarm distance of existing product is realized by regulating tunable capacitor, as Chinese patent 92213201.1 and Chinese patent 99229176.3, the shortcoming of this structure is, when not transferring tunable capacitor during follow-up the maintenance through the maintenance personal who trains, to destroy the alarm distance of setting when originally dispatching from the factory, the alarm distance of alarm will lose report to the police or alarm distance less than safe distance.
Existing product is with the self check button more, and as Chinese patent 92213201.1 and Chinese patent 99229176.3, the alarm sound the when shortcoming of this structure is to press the self check button is the sound of the voicefrequency circuit at circuit rear portion, and it can only reflect that battery has.This sound is absolutely not that warning circuit is sensed high-voltage ac power and the alarm sound that produces, i.e. this kind self check is not the whole circuit self check, can not determine whether this device is reliable so the user presses the self check button.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the protection against electric shock pre-alarm wrist-watch that the protection against electric shock warning is effective.
Technical solution of the present utility model is:
A kind of protection against electric shock pre-alarm wrist-watch, comprise the table body, it is characterized in that: in the cavity between the wrist-watch surface of table in the body and the wrist-watch watch crystal, be provided with the wrist-watch internal shadow ring of antenna effect, the wrist-watch internal shadow ring by the antenna brace be arranged on the protection against electric shock prealarm circuit of showing in the body and be connected.
The wrist-watch internal shadow ring is close to the watch case setting, is provided with insulated ring between wrist-watch internal shadow ring and watch case, is provided with insulating trip between wrist-watch internal shadow ring and wrist-watch surface.The protection against electric shock prealarm circuit is the protection against electric shock prealarm circuit that has piezo.Piezo is arranged on wrist-watch bonnet inboard, and contacts with the wrist-watch bonnet.
The protection against electric shock prealarm circuit comprises reception, the regulating circuit that is connected and initial alarm distance is risen regulating action with the wrist-watch internal shadow ring that plays the antenna effect, reception, regulating circuit are connected with integrated circuit, integrated circuit is connected with the base stage of power amplifier by a resistance, an end links to each other with the collector of power amplifier after piezo and the telefault parallel connection, the other end is connected with anode, and battery provides power supply for integrated circuit.Integrated circuit is connected with the resistance of regulating buzzer call frequency speed.
The utility model is rational in infrastructure, and protection against electric shock is reported to the police effective, and the internal shadow ring of wrist-watch is the receiving antenna of protection against electric shock prealarm circuit, is again the internal shadow ring in the wrist-watch, has improved safety and unfailing performance.Have timing and alarming in short range of electric power dual-use function.Even the workman of being also advantageous in that of the present utility model breaks, bumps Watch glass in construction, this alarm still can continue to report to the police, thereby has improved its security performance.The self check person of being to use of the present utility model is positioned over this device in the low-voltage alternating current power supply, and this device can be reported to the police, and illustrates that this device is normal, can use, thereby guarantee and improved its security performance.

Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the configuration diagram of internal shadow ring among Fig. 1, antenna brace part.
Fig. 3 is protection against electric shock prealarm circuit figure.
Embodiment:
A kind of protection against electric shock pre-alarm wrist-watch, comprise the table body, in the cavity between the wrist-watch surface 1 of table in the body and the wrist-watch watch crystal 2, be provided with the wrist-watch internal shadow ring 3 of antenna effect, the wrist-watch internal shadow ring by antenna brace 4 be arranged on the protection against electric shock prealarm circuit of showing in the body 5 and be connected.
The wrist-watch internal shadow ring is close to the watch case setting, is provided with insulated ring 6 between wrist-watch internal shadow ring and watch case 10, is provided with insulating trip 7 between wrist-watch internal shadow ring and wrist-watch surface.The protection against electric shock prealarm circuit is the protection against electric shock prealarm circuit that has piezo 8.Piezo 8 is arranged on wrist-watch bonnet 9 inboards, and contacts with the wrist-watch bonnet.Also have antenna attachment screw 11, watch glass assembling nylon ring 12, carriage 13 etc. among the figure.
The protection against electric shock prealarm circuit comprises reception, the regulating circuit that is connected and initial alarm distance is risen regulating action with the wrist-watch internal shadow ring that plays the antenna effect, reception, regulating circuit are connected with integrated circuit, integrated circuit is connected with the base stage of power amplifier by a resistance, an end links to each other with the collector of power amplifier after piezo and the telefault parallel connection, the other end is connected with anode, and battery provides power supply for integrated circuit.Integrated circuit is connected with the resistance of regulating buzzer call frequency speed.
Principle of work of the present utility model is:
The utility model is during near high-voltage ac power, sense an alternation power frequency electric field by the receiving antenna in the surperficial assembly that contains receiving antenna, the surperficial assembly and the resistance R 1 that contain receiving antenna, R2, R3 and integrated circuit are connected, regulate R1, R2, the resistance of R3 is regulated the initial alarm distance when receiving high-voltage ac power, in case can not transfer when distance setting keeps in repair fortunately when dispatching from the factory, thereby guarantee and the security performance integrated circuit U1 (model DHZ01) that improved it is transformed into this electric field signal by the high-impedance amplifier of internal system the electric signal of same frequency.The reminds people that pipes by buzzer P has entered the high-voltage electric field scope and has warned, as long as exist at the high-voltage alternating electric field, this warning system can continue to report to the police, in case withdraw electric field, chimes of doom just stops.Frequency speed during buzzer call can be realized by the resistance of regulating resistance R 4.
