Abstract
Safety helmet with alarm for high voltage relates to a kind of voltage check device, is mainly used in the security protection of 27.5KV to 220KV transmission line maintenance and equipment installation exercise personnel, meets Danger Electric shock risk and can report to the police automatically.Principal character be safety helmet under high tension voltage, alarm does not need powered battery, makes sounder work send alarm sound by electric field energy.Major advantage is to need not battery to make power supply, does not have energy consumption, and the life-span is long, need not keep in repair, and self-checking unit is housed on the safety helmet, and safe and reliable, alarm encapsulates with synthetic resin.Have function rainproof, moistureproof, anticollision, use extensively.
Description
The present invention relates to a kind of voltage check device, be mainly used in 27, the above transmission line maintenance of 5KV and equipment installation exercise personnel's security protection, meet Danger Electric shock risk and can report to the police automatically.
In electric railway, mine, power transmission and transformation line (station), electric power system such as city trolley bus, sub., the electrical safety cap that the operating personnel that maintenance and inspection and equipment are installed generally uses is the cap shell of being made by insulating material, cap tire and frenulum are formed, get an electric shock with the prevention head only and junk kicks to the head or collides the regional alarm free indication that is strayed into that Keep Clear-High Voltage to the operator, easily cause the operating personnel to be strayed into the Danger Electric shock risk zone and cause electric shock accidents.The safety helmet that the band that now also instigating is provided with Chinese patent CN87209558 is reported to the police, be to be the energy with the battery, be called " active safety helmet with alarm ", be also referred to as " Safety helmet with an electric alarm means ", in actual use owing to have cell voltage fluctuation, self discharge, loose contact, other condition effect such as cell voltage reduction in use and operating environment easily cause warning malfunctioning, unreliable.And need often change battery.The test pencil that uses all needs the contact electrification thing during high and low pressure electroscope inspection at present, and is also dangerous.More than several instruments all can not report to the police to the operating personnel in the district that is strayed into that Keep Clear-High Voltage and can not detect the breakpoint of closed-loop, so the electric shock casualty accident happens occasionally.
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of simple in structure, do not need battery, anti-junk kicks to the head and collides, and the passive safety helmet with alarm of the high pressure that is not subjected to the external condition environmental interference, when the user near having Danger Electric shock risk when zone, can send audible warning automatically, the prompting user takes care.
Technical scheme of the present invention is achieved in that safety helmet with alarm for high voltage, constitute safety helmet by cap shell, cap tire, hatband etc., in cap shell inside receiving antenna is housed, alarm, sounder, the input end and the receiving antenna of alarm link, output terminal and sounder join, its special character is safety helmet in high-voltage electric field, and alarm does not need powered battery, makes sounder work send alarm sound by electric field energy.Receiving antenna in the scheme adopts metallic film to manufacture, and hatband adopts metallic conduction cloth to manufacture, and sounder adopts the piezoelectric ceramics hummer, and it is packed into help in the operatic tunes.Alarm adopts the synthetic resin overall package.Self check contact stud (hole) is housed on the safety helmet, is used for the alarm of safety helmet is carried out self check.
The present invention's advantage compared with prior art is:
1, need not battery and make power supply, do not have energy consumption, so the life-span is long, freedom from repairs, on-the-spot use certificate contract quotation is alert sensitive, and accurately and reliably, resolution performance is strong.
2, because the safety helmet alarm does not have energy consumption, so do not add switch, cause flase drop in order to avoid the user forgets switch, electric shock accidents occurs, all just work in Keep Clear-High Voltage zone sent acoustic signal, just quits work automatically when the user leaves the hazardous location.
3, warning circuit encapsulates with synthetic resin, and the life-span is long, and is shock-resistant, is not afraid of rainwater and humidity.
Now describe most preferred embodiment of the present invention in conjunction with the accompanying drawings in detail:
Fig. 1 is the passive safety helmet with alarm structural representation of helmet-type.
Fig. 2 is the electrical schematic diagram of the passive safety helmet with alarm of helmet-type.
Among the figure:
1, cap shell 2, receiving antenna 3, hat lining 4, sounder 5, alarm 6, self check contact stud 7, hatband 8, earflap 9, cap tire 10, rectifier 11, charger 12, oscillator 13, help the operatic tunes
The present invention has three kinds of patterns, divide summer type and winter type, winter, type was divided into helmet-type and fur cap formula again.Now do most preferred embodiment as shown in Figure 1 with the helmet-type safety helmet with alarm.
The passive safety helmet with alarm of helmet-type high pressure is by cap shell 1, cap tire 9, the institutes such as hatband 7 that make of conductive fabric constitute, on the cap tire 9 of cap shell 1 inboard, alarm 5 is installed, the input end of alarm 5 is connected with ground wire hatband 7 with receiving antenna 2, output terminal and acoustical generator 4 join, the electrical schematic diagram of alarm 5 as shown in Figure 2, the rectifier 10 that it is made of diode DI-D4, charger 11 and resistance R I-R3 triode BGI that capacitor C constitutes, the oscillator that BG2 constitutes is formed and is encapsulated with synthetic resin, receiving antenna 2 is with 0, the Copper Foil that 1MM is thick is made, ground wire is with hatband 7 riveted joints of making of conductive fabric with lead, sounder 4 adopts the piezoelectricity hummers and piezoelectric ceramic piece is packed into and helps in the operatic tunes 13, self check contact rivet 6 is housed on the safety helmet connects with external autoscope and test.
The embodiment course of work is as follows:
When the operation personnel wear this safety helmet near charged object, antenna 2 receives the electric field induction signal, producing exchange current in the circuit of warning 5 gives capacitor 11 chargings after bridge rectifier 10 rectifications, when charging voltage reaches oscillator 12 operating voltage 10, oscillator 12 is started working, and stream produces tonepulse by sounder 4 and sends sound, the size of its audio frequency and capacitor 11, the height of charged object voltage, the design of the distance of distance and receiving antenna 2 has direct relation.
Safety helmet with alarm in use, the user is worn over safety helmet on the head, fastens hatband 7, just can carry out electric operation.The present invention is 27, under the 5KV line voltage distribution, and as user during apart from the reference position of the 3-5M of supply line, safety helmet with alarm promptly sends the alerting signal that ticks, and the warning user takes care.
