Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
A kind of safe distance monitoring alarm schematic diagram that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of safe distance monitoring alarm schematic diagram that Fig. 1 provides for the utility model.
In a kind of embodiment, a kind of safe distance monitoring alarm that the utility model provides, comprises stadimeter 101, safe distance comparer 102 and alarm 103.
Wherein, stadimeter 101 is measured the distance between described construction equipment and electrified body and is produced measuring distance, in work progress, the arm of construction equipment will carry out operation near the electrified body as high-tension bus-bar etc. usually, inevitably the electrified bodys such as high-tension bus-bar are touched in close process, and arm when operation and the distance of electrified body all changing at any time, therefore, need stadimeter to monitor distance therebetween in real time.
Further, in order to reduce weight and the volume of safe distance monitoring alarm, and improve and measure accuracy rate, stadimeter 101 is preferably laser range finder, reason is laser range finder is utilize laser to carry out the instrument of Accurate Determining to the distance of target, it is lightweight, volume is little, speed simple to operate fast and accurately, its error is only 1/5th of other optical range finder to hundreds of/mono-.
Safe distance comparer 102 for more described measuring distance and safe distance size obtain comparative result information, described safe distance comparer 102 is connected with described stadimeter 101.
Concrete, according to staff's construction experience preset security distance, also can pass through apparatus measures safe distance.Due in electric system, the voltage of high-tension bus-bar is different, the electric field intensity produced is different, according to different electric field intensity, safe distance between construction equipment and hi-line is also not quite similar, therefore, if construction equipment operation under different high-tension bus-bars, be only inaccurate with same default safe distance.
Further, in order to improve measure safe distance accuracy rate, present embodiment carries out measuring to safe distance by instrument.Safe distance monitoring alarm also comprises the electric-field sensor measuring described safe distance information, and electric-field sensor is preferably spherical electric-field sensor.Electric-field sensor can carry out the safe distance between the high-tension bus-bar of different voltage and construction equipment accurately measuring.Such as, the safe distance of the safe distance of 35kv high-tension bus-bar to be the safe distance of 3m, 110kv high-tension bus-bar be 4.5m, 220kv high-tension bus-bar is 5m.
By compare and measure distance and safe distance size obtain comparative result information, wherein comparative result information specifically comprises: construction equipment is around same electrified body when operation, measurement obtains safe distance, when measuring distance is less than described safe distance time, the comparative result information of generation is the operation of staff's emergent stopping; When measuring distance is greater than described safe distance time, and when measuring distance is less than the first safe distance threshold value, comparative result information, for entering higher-pressure region, please staff slowly operate; When measuring distance is greater than described safe distance time, and when measuring distance is greater than the first safe distance threshold value, comparative result information, for being safe from danger, please staff operate arbitrarily.Such as, when voltage of high-voltage line is 110kv, safe distance is 4-5m, first safe distance threshold value is 5-7m, and when voltage of high-voltage line is 2200kv, safe distance is 6-8m, first safe distance threshold value is 8-12m, when voltage of high-voltage line is 550kv, safe distance is 8-10m, and the first safe distance threshold value is 10-14m.
Alarm 103 is for receiving described comparative result information and sending corresponding alerting signal, and described alarm 103 is connected with described safe distance comparer 102.Described alarm 103 is preferably audible-visual annunciator.The prompt tone different according to different results contrast deliverings or/and prompting light, such as, comparative result information for staff's emergent stopping operate time, prompting light is ruddiness, prompt tone be ask staff's emergent stopping operate; Comparative result information is for entering higher-pressure region, and when asking staff slowly to operate, prompting light is yellow light, and prompt tone, for entering higher-pressure region, please staff slowly operate; Comparative result information is for being safe from danger, and when asking staff to operate arbitrarily, prompting light is green glow.
Further, in order to better be fixed on construction equipment by safe distance monitoring alarm, the support 104 be connected with described alarm is also comprised.Described support 104 is preferably magnet steel support.Magnet steel support can be adsorbed on arm surface, easy for installation, and dismounting easily.
The utility model additionally provides a kind of construction equipment, and comprise at least one safe distance monitoring alarm as described in above-mentioned any one, described safe distance monitoring alarm is arranged at the arm top of described construction equipment.The high-tension bus-bar that multiple safe distance monitoring alarm realizes multiple directions carries out distance early warning, improves the accuracy rate of warning.
For the safety of person during guarantee Overhaul site use Work tool, realize the supervision and management of Overhaul site overall process, the utility model provide a kind of can between Real-Time Monitoring construction equipment and electrified body safe distance safe distance monitoring alarm, this device can distance between Real-Time Monitoring construction equipment and electrified body, time within the safe distance that facility move to setting, monitoring device sends warning, prompting staff, and between facility and electrified body, safe distance is not enough.Use safety during Large Construction facility to provide reliable basis for staff in transformer station overhauls, realize the Whole Course Management to Overhaul site safety.
The utility model is reasonable in design, structure is simple, be widely used in station working site, the mode of going forward one by one is adopted to describe to each embodiment in construction equipment and charged instructions, what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
