Abstract
The utility model discloses an acoustic-optic warning board for preventing false electric shock; a detection unit, a triggering unit and an acoustic-optic alarming unit which are connected with the power supply are integrated in a character warning board, the detection unit is electrically connected with the triggering unit which is electrically connected with the acoustic-optic alarming unit. The acoustic-optic warning board has rational structure and good popularity, can effectively prevent the action that people step across the prohibition area and can be widely applied to electric power plants, transformer stations, high and low voltage power supply rooms and other power utilization field.
Description
Technical field
The utility model relates to the acousto-optic warning board that a kind of electric system prevents error shock.
Background technology
Electric system at present is to guarantee the person and the device security of electric power worker in power construction, operation and overhaul of the equipments process, will use a kind of warning sign usually, existing warning sign all be with " halt, Keep Clear-High Voltage! " this class pure words warning sign, the caution effect of this warning sign is relatively poor, especially under the not good situation of operating personnel's state of mind, still might cross the pure words warning sign and lead to the error shock accident; Cause present electric power person error shock accident still to happen occasionally.According to research with to the accident statistics reference state of mind at work is a whether safe crucial factor.Therefore, how can wake the operating personnel up from dangerous edge, reduce the generation of electric system person error shock accident, be the task of top priority.
The purpose of this utility model is to overcome the deficiency of existing pure words warning sign, and a kind of acousto-optic warning board that prevents error shock of warning better effects if is provided.
The technical solution of the utility model is: the integrated probe unit that is connected with power supply, trigger element, acousto-optic warning unit in a literal warning sign, and described probe unit is electrically connected with trigger element, and trigger element is electrically connected with acousto-optic warning unit.
Described probe unit is to be made of thermal infrared detecting device or laser ranging system or sound ranging device.Described thermal infrared detecting device or laser ranging system or sound ranging device are prior arts.
Described trigger element is to be made of trigger and circuit thereof.When the signal indicating that receives probe unit when it has the effractor, can in time trigger acousto-optic warning unit.Described trigger and circuit thereof are prior art.
Described acousto-optic warning unit is the audible-visual annunciator that is made of speech chip, loudspeaker and light emitting diode, and wherein loudspeaker and light emitting diode are electrically connected with speech chip, and speech chip is electrically connected with trigger element.Described audible-visual annunciator is a prior art.When speech chip is received the alerting signal of trigger element, in time send as " halt, Keep Clear-High Voltage " or phonetic warnings such as " No switching ons; circuit has the people to work ", and send red flash of light caution simultaneously, wake the operating personnel up from dangerous edge, thereby reach the purpose of avoiding accident.
Apparatus structure of the present utility model is reasonable, and versatility is good, and can more effectively stop forbidden more is to be widely used in power plant, transformer station, high and low voltage electric distribution room and other electricity consumption fields.
Description of drawings
Fig. 1 connects block diagram for the utility model structure;
Fig. 2 is the outside surface design drawing of embodiment 1 warning sign.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1:
With reference to accompanying drawing 1: 1 li of a literal warning sign integrated the probe unit 2 that is connected with power supply, trigger element 3, acousto-optic warning unit 4, described probe unit 2 is electrically connected with trigger element 3, trigger element 3 is electrically connected with acousto-optic warning unit 4.Acousto-optic warning unit is that its loudspeaker 5 can send audio alert by the audible-visual annunciator that is made of speech chip, loudspeaker and light emitting diode in the prior art, and 6 of its light emitting diodes send red flash of light.
The probe unit of present embodiment is to be made of the thermal infrared detecting device in the prior art.
The trigger element of present embodiment is to be made of trigger in the prior art and circuit thereof.
With reference to accompanying drawing 2: the outside surface of the literal warning sign 1 of present embodiment with big word with " halt, Keep Clear-High Voltage ", its probe unit 2 is installed in the middle part of literal warning sign 1, the loudspeaker 5 of acousto-optic warning unit 4 is installed in a jiao of literal warning sign 1, marks the large size exclamation mark and the arrow of red flash of light respectively with the light emitting diode 6 of acousto-optic warning unit in two sides of literal " halt, Keep Clear-High Voltage ".
Hang this warning sign at the electric operating scene that might jeopardize personal safety during use, as operation personnel during because of carelessness near warning sign, infrared detector detects moving heat source, and by the flip-flop toggle acousto-optic warning unit, acousto-optic warning unit in time sends the phonetic warning as " halting; Keep Clear-High Voltage ", and send red photoelectricity caution of glistening, and remind the operating personnel who enters the forbidden zone, wake the operating personnel up, it is stopped at outside the defence area, thereby reach the purpose of avoiding accident.
Embodiment 2:
As different from Example 1: the probe unit of present embodiment is to be made of laser ranging system.
Hang this warning sign on the equipment of quiescing, as operation personnel during because of carelessness near this warning sign (if having the people to invade in set distance range), laser ranging system is by the flip-flop toggle acousto-optic warning unit; , acousto-optic warning unit in time sends the phonetic warning as " No switching on, circuit have the people to work ", and sends red flashing signal.Wake the operating personnel up from dangerous edge, thereby reach the purpose of avoiding accident.
Embodiment 3:
As different from Example 2: the probe unit of present embodiment is to be made of the sound ranging device.
Claims (4)
