Abstract
The utility model relates to the technical field of electric power mining safety protection and discloses a stainless steel warning fence with a voice warning device. The stainless steel warning fence comprises a stainless steel fence and the voice warning device, wherein the voice warning device is electrically connected to an input end 2 corner of a time base integrated package IC1 (integrated circuit) by an induction metal wire through a junction field-effect tube VT2; an output end 3 corner of the time base integrated package IC1 is electrically connected an input end 2 corner of a language integrated package IC2 through a potentiometer RP2, and an output end 4 corner of the language integrated package IC2 is connected to a loudspeaker BL through an audio amplifying triode VT1. Due to the stainless steel warning fence, workers can be reminded of work safety when power transformation equipment of a power system is constructed or overhauled; the warning voice of keeping away from high voltage danger can be performed, so that the workers in the operating crew can be concerned about one another in work, and the safety protection is increased in the construction and overhaul work.
Description
Technical field
The utility model relates to electric power industrial and mineral safety protection technique field, relates in particular to a kind of stainless steel caution fence with the phonetic warning device.
Background technology
At present, telescopic stainless steel fence has become electric power enterprise transformer station and industrial and mining enterprises and construction site and prevented one of important measures of taking safely: telescopic stainless steel fence is connected and composed by strap by stainless steel column, when converting equipment overhauls, the staff requires the installing fence according to service work, purpose is to prevent that the service work personnel from surmounting fence, cause construction violating the regulations, or personal injury; Because the staff is when maintenance, mistake is bumped or striking strap or stainless steel column easily, causes fence to move, between the mistakenly entering into charged battery limits.
Summary of the invention
In order to overcome existing technical deficiency, the utility model purpose provides a kind of stainless steel caution fence with the phonetic warning device.Can when construction of power system converting equipment or maintenance, remind staff's safety when work.Promptly send the prompt tone of " halt Keep Clear-High Voltage ", the member of shift is concerned about when work mutually, make the work of Construction and Maintenance increase security protection.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of stainless steel caution fence with the phonetic warning device, comprise: stainless steel fence and phonetic warning device, described phonetic warning device, base integrated package IC1 input is 2 jiaos when being electrically connected to by technotron VT2 by the induction wire, 3 jiaos of time base integrated package IC1 outputs are electrically connected to 2 jiaos of language integrated package IC2 inputs by potentiometer RP2, and 4 jiaos of language integrated package IC2 outputs are connected to loudspeaker BL by audio frequency amplifying triode VT1.
Owing to adopt as above technical scheme, the utlity model has following superiority:
A kind of stainless steel caution fence with the phonetic warning device adopts flexible the enclosing of safety alarm device and stainless steel to block effective composition that combines.As near fence the time, will send electricity the voice suggestion that Danger! Keep Away, promptly send the prompt tone of " halt Keep Clear-High Voltage ", the member of shift is concerned about when work mutually, make the Construction and Maintenance work safety increase protection.
Description of drawings
A kind of circuit theory diagrams of warning fence with the stainless steel of phonetic warning device of Fig. 1.
The specific embodiment
As shown in Figure 1: a kind of stainless steel caution fence with the phonetic warning device, comprise: stainless steel fence and phonetic warning device, described phonetic warning device, base integrated package IC1 input is 2 jiaos when being electrically connected to by technotron VT2 by the induction wire, 3 jiaos of time base integrated package IC1 outputs are electrically connected to 2 jiaos of language integrated package IC2 inputs by potentiometer RP2, and 4 jiaos of language integrated package IC2 outputs are connected to loudspeaker BL by audio frequency amplifying triode VT1.
During use, the utility model is to penetrate wire in the fence strap that utilizes in the stainless steel column jecket of telescopic stainless steel fence, the induction wire is by technotron VT2, time base integrated package IC1, language integrated package IC2, and audio-frequency amplifier tube VT1 and loudspeaker BL and dc source GB form.
When the close induction of people wire 0.3m-0.5m, the induced signal of human body can make the drain electrode of VT2, the resistance value between the source electrode increase, the 2 pin current potentials of time base integrated package IC1 are lower than VCC/3, circuit upset in the IC1, its 3 pin has low level to become high level, and the language integrated circuit is worked because of triggering, and the speech signal of IC2 the 4th pin output is through VT1, after the amplification, send language prompting sound by loudspeaker BL.Promptly send the prompt tone of " halt Keep Clear-High Voltage ", the resistance value of regulator potentiometer RP1 and RP2 can change the sensitivity of circuit.
