Abstract
The utility model provides a testing fence which comprises a plurality of protective guards and a plurality of warning indicators. The protective guards are connected along the longitudinal direction and the warning indicators are arranged at the protective guards with intervals. Each of the warning indicators comprises an articulatory system, a sensor for detecting signals produced through people's movements in the precautionary area and a detector which is electrically connected with the sensor to receive signals sent by the sensor and trigger the articulatory system to make a sound. According to the testing fence, the testing fence is formed by connecting a plurality of protective guards and warning indicators capable of making a sound are arranged at the protective guards. When non-staff are close to the testing fence, the sensor senses the non-staff and sends signals, and then the detector detects the signals sent by the sensor to trigger the articulatory system to make an alarm to prevent the non-staff from getting across the precautionary area into the testing site mistakenly and avoid the danger of electric shock.202850595Y.

Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation according to test fence of the present utility model;
Fig. 2 is the schematic diagram according to the alarm of test fence of the present utility model; And
Fig. 3 is the schematic diagram according to the literal warning sign of test fence of the present utility model.
The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Referring to Fig. 1, this test fence comprises a plurality of protective guards 10, and protective guard 10 can a plurality of independent assortments, and a plurality of protective guards 10 are connected along himself length direction, and arrangement convenience is quick, and stability is high, integral arrangement is attractive in appearance.Referring to Fig. 2, this test fence also comprises a plurality of attention devices 20, being arranged on the protective guard 10 of interval.This attention device 20 comprises articulatory system, sensor and probe.The signal that the signal that sensor produces for detection of the human motion in the security area, probe are connected with sensor electrical and receiving sensor sends is sounded to trigger articulatory system.
The testing site mostly is greatly transformer station, because many working units in the transformer station, on-the-spot confusion, constructor are more, periphery in the testing site can arrange the test fence that the utility model provides, this test is enclosed by a plurality of protective guards 10 and is formed by connecting along self length direction, and protective guard 10 arrange can sounding attention device 20.Test fence sensor when the inoperative personnel are arranged near the test fence with attention device 20 can be sensed this movable signal and send signal, and probe detects the signal that sensor sends, and triggers immediately articulatory system and sounds the alarm.This test fence can prevent effectively that the inoperative personnel from passing through warning tape and being strayed into the danger that person electric shock occurs in the testing site, and then has improved the safety factor of working site.
Preferably, the middle part of each protective guard arranges an attention device 20, and per 10 meters put 6 attention devices 20 at least.Such design can stop to cause attention device 20 can't make the phenomenon of correct response because of the blind area that may occur in the fence coverage.
Preferably, attention device 20 also comprises luminescent system, and this luminescent system is electrically connected with probe, and it is luminous that probe can trigger luminescent system when detecting the signal that sensor sends.In case the people is arranged near in the security area, attention device 20 will be sounded and light-emitting caution inoperative personnel are strayed into.Luminous and pronunciation is carried out simultaneously, efficiently solves a difficult problem of testing insufficient light night, and safety is higher, and has improved test efficiency.
Sensor in above-described embodiment is infrared sensor, and the distance of reaction of infrared sensor is H, H 〉=5m.
Particularly, attention device 20 adopts light adjusting system and the heat of multielement array structure to release infrared sensor, and probe is the CMOS special IC.Receive the variation of the faint infrared radiation signal of 5-20 μ m that security area internal cause human motion produces by probe, to trigger the light adjusting system voice that give a warning.
The advantage of this attention device 20 is as follows: the horizontal view angle is 84 degree, and the vertical angle of view is 14 degree, and induction range is large, and is highly sensitive; Warning lamp on attention device 20 and the attention device 20 adopts the 4.5V battery to be power supply, and is safe and reliable; Work the stand-by state electric current less than 0.5mA, longevity of service; By day, night, indoor and outdoors all can work, and is not subjected to the job site climatic effect.
Referring to Fig. 1, the test fence also comprises connecting struts 30, is arranged between the adjacent protective guard 10, and connecting struts 30 is connected with the protective guard 10 of both sides respectively.Connecting struts 30 has guaranteed that this test fence is firm, enough flexibilities and enough mechanical strengths are arranged, and lightly is convenient to dismantle, carry, transport and deposit.Have fence supports between per two fans, be convenient to the independent assortment installing.
Referring to Fig. 1 and Fig. 3, the test fence also comprises literal warning sign 40, can be with the printed words of " halt Keep Clear-High Voltage " and caution figure etc. on literal warning sign 40.Literal warning sign 40 is arranged on each protective guard 10, and is positioned at the middle part of each protective guard 10.Can write caveat such as " halt Keep Clear-High Voltage " on the literal warning sign 40, further to play the effect of caution.The personage that obstacle is particularly arranged for hearing, the existence of literal warning sign 40 is just extremely important.
The external surface plastic-blasting of protective guard 10 is about to plastispray at the external surface of protective guard 10.The presentation quality of plastic-blasting rear protective guard 10 is excellent, and adhesive power and mechanical strength are strong, and coating anticorrosive anti-wear ability exceeds much behind the plastic-blasting.
Preferably, the external surface of protective guard 10 reflecting strips that has been sticked especially can be selected red reflecting strips, and red color is comparatively bright-coloured, can play preferably warning function.
Preferably, protective guard 10 is that the steel pipe of 20mm is made by diameter, is guaranteeing to have reached again firm effect under the light and handy prerequisite.Certainly, protective guard 10 also can be made with insulation materials, and is safe and reliable.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
1, the test fence can sounding alarm, prevents that the inoperative personnel from passing through warning tape and being strayed into the testing site danger that the person gets an electric shock occurs;
2, the test fence can be luminous, also can play the effect of caution night;
3, protective guard combination free, energy Fast Installation, dismounting, easy to use;
4, safety improves greatly.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
