The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
In conjunction with Fig. 1 to Fig. 3, a kind of static electricity earthing device of guaranteeing the tank car effective grounding comprises resistance detection module 11, capacitive detection module 12, controller 2, annunciator 3, power supply 4, clip 5 and touch block 6.Five connection terminals are arranged on the said touch block 6; First connection terminal 61 and second connection terminal 62 are connected two chucks of clip 5 respectively, and the inner end surface of 5 two chucks of clip is provided with top, have on the chuck two top; Have on another chuck one top, three top does not contact.The 3rd connection terminal 63 is connected ground stud 7 with the 4th connection terminal 64; First connection terminal 61 connects resistance detection module 11 and capacitive detection module 12 respectively; Resistance detection module 11 is connected controller 2 respectively with capacitive detection module 12; Controller 2 is connected with the 4th connection terminal 64; Annunciator 3, power supply 4 are connected respectively with controller 2, and said second connection terminal 62 is connected with between the two with the 3rd connection terminal 63 both are connected or open circuited detection commutation circuit 8, detect commutation circuit 8 and are connected with controller 2.Said capacitive detection module 12 is made up of frequency generating circuit that is connected and capacitive detection circuit.Controller 2 is connected with the 5th connection terminal 65, and controller 2 sends high level signal to the five connection terminals 65, the five connection terminals 65 coupled condition plates 9.
Judge whether clip contacts good principle introduction:
In the time of clip and car body bad contact; Can produce a bigger and unsettled resistance value; Around this principle; Clip on car body, through detecting the resistance value of the folded conductor of clip between first connection terminal and the 4th connection terminal, is judged whether clip contacts well with car body.
Judge whether clip is clipped in the principle introduction on the tank car main body:
Have a different capacitance between different conductors and the earth, under the same condition, the volume of conductor is big more; Whether capacitance is also big more, around this principle, can detect clip and clip on the tank car main body; If clip on the smaller conductor; For example: contact bad handle, hook etc. with vehicle main body, detected capacitance is just smaller, and when clipping on the main body of tank car; Detected capacitance is bigger, and the size that detects capacitance through judgement just can judge whether clip is to clip on the main body of tank car.
After use, clip were taken down from the state plate, as shown in Figure 1, controller was connected second connection terminal through detecting commutation circuit with the 3rd connection terminal, get into the resistance detection process.If detection resistance value overgauge resistance value representes that promptly opening circuit appears in bad contact or loop, this moment, annunciator sent a kind of chimes of doom, reminded the operator, and less than the standard electric resistance, resistance detection is passed through as if detection resistance value.As shown in Figure 2, controller breaks off second connection terminal and the 3rd connection terminal through detecting commutation circuit, gets into the capacitance detecting process.Frequency generating circuit at first produces a frequency values; When there were a different capacitance in the folded conductor of clip and the earth, frequency generating circuit changed frequency values, compares calculating to the frequency values that reads back through capacitive detection circuit and controller; Draw the capacitance between conductor and the earth; If detect capacitance less than the standard capacitance value, promptly clip clips on the smaller conductor, for example: contact bad handle, hook with vehicle main body; This moment, annunciator sent another kind of chimes of doom, reminded the operator.If detect capacitance overgauge capacitance, promptly clip clips on the main body of tank car, and capacitance detecting is passed through.Detect commutation circuit and switch to the resistance detection process once more, lead static that destatic equipment produce as long as detection resistance value less than the standard electric resistance, will be kept the resistance detection process always this moment.Whenever when as long as clip clips on the state plate, because clip ground connection this moment, the high level of the 5th connection terminal is dragged down, controller adjustment entire circuit will get into low-power consumption mode, save electric weight, the tenure of use of prolongation equipment.
This static electricity earthing device all is oil resistant copper core cables of 2 * 1.5 square millimeters with clip bonded assembly cable and the cable that is connected ground stud, the acid-fast alkali-proof withstanding corrosion, and it is good that tension is dragged performance, can satisfy on-the-spot more abominable environment for use.Power supply uses high power lithium battery, need not change battery under the normal condition of service.What controller adopted is the micro controller system of super low-power consumption, and the electric current under the dormancy situation is minimum, and power consumption is few, has strengthened the period of service of device.What circuit part adopted is that epoxy resin waters envelope, and battery is also watered envelope by epoxy resin fully, anti-moisture, and the short circuit problem that reason causes such as do not worry shaking, increased the safety factor of on-the-spot use.It is a module whole that the circuit of whole measuring ability, power supply and annunciator module are watered envelope, is convenient to on-the-spot replacement.
In a word, this kind static electricity earthing device can be judged the bad earth phenomenon; With the form prompting operation person of audible alarm, can judge whether clip is received on the main body of car, if clip does not clip on the main body of car; With the form prompting operation person of audible alarm, stop not connect car or the false situation that connects car.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technical personnel in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
