Description

Sun power electrostatic grounding alarm

Technical field the utility model belongs to the alarm technical field, is specifically related to a kind of sun power electrostatic grounding alarm.

Background technology static is the accumulation of same sex bound charge, just can cause harm even disaster when running up to a certain degree, the blast that causes as static discharge, interfere with communications etc.The reason that produces static is a lot, as friction, induction, polarization or the like.Producing static as fuel charger mainly is that in whole refueling process, fuel oil all will produce static under situations such as flowing, filter, mix, wash, spray, annotate, rock in work.When the generation speed of static charge is higher than leakage rate, will build up of electrostatic charge.When the potential difference (PD) of two articles reaches 300 volts when above, will produce electric discharge phenomena, and produce electric spark.The spark energy of static discharge is if reached or greater than the minimum ignition energy of combustible on every side, and the aerial concentration of combustible or content are also in the explosion limits scope time, just can set off an explosion at once or burn, for preventing the generation of the fire failure that static causes, the precautionary measures to be taked of killing, at present, the development of static warning utensil more and more causes people's attention.

The summary of the invention the purpose of this utility model provides a kind of sun power electrostatic grounding alarm that utilizes sun power as the energy, can effectively prevent the generation of the accidents such as fire that static causes, to overcome the deficiencies in the prior art.

To achieve these goals, the utility model sun power electrostatic grounding alarm comprises the aluminium box, and said aluminium box peripheral hardware solar panel and audible-visual annunciator are established super low-power consumption microprocessor microcontroller and rechargeable battery in the aluminium box; External eight leads of said single-chip microcomputer, two ground studs wherein, be used for detection alarm device ground connection situation, article two, connect ground clamp, be used for clamping the working point, be used for testing point ground connection situation, article two, connect audible-visual annunciator, the indication that is used for reporting to the police, two connect solar panel in addition, and the rechargeable battery of inside is charged; Entire circuit is controlled by the super low-power consumption microprocessor microcontroller, monitoring, alarming; Peripheral circuit is made up of sample circuit, power supply-charging circuit, sound and light alarm, reset test circuit.

The utility model reasonable in design, have characteristics such as super low-power consumption design, automatic detection in 24 hours, solar recharging, rechargeable battery powered, long service life, anti-vibration, protection against the tide, non-maintaining, sound and light alarm, can effectively prevent the generation of the accidents such as fire that static causes; The rainproof design of its aluminium box outer container, antirust durable, easy for installation can be installed in the refuelling station, the fire hazard that causes with electrostatic prevention.

Description of drawings Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model system chart;

Fig. 3 is the utility model board structure of circuit synoptic diagram,

Embodiment is according to Fig. 1, Fig. 2, Fig. 3, and it comprises aluminium box 1 the utility model, aluminium box 1 peripheral hardware solar panel J ₃3 and audible-visual annunciator 1, establish super low-power consumption microprocessor microcontroller 5 and rechargeable battery J in the aluminium box 1 ₄4; Single-chip microcomputer 5 external eight leads, wherein two ground stud J ₂6 the 3rd and the 4th binding post, two meet ground clamp J ₂6 the 1st and the 2nd binding post, two connect audible-visual annunciator 2, and two meet solar panel J in addition ₃3; Peripheral circuit is made up of sample circuit 9, power supply-charging circuit 8, sound and light alarm 2 and reset test circuit 10.

Establish comparer 7 in the single-chip microcomputer 5.

This sun power electrostatic grounding alarm is that compliant requires, whether bonding line connects firmly, whether static elimination path has formed and the environmental protection warning device that designs for, grounding resistance of transmission value whether intact at earthing device.Adopt the little process chip of super low-power consumption, electronic circuit continuous detecting connection device loop and ground terminal loop resistance value, be connected by top, ground connection clamp, ground clamp cable, earthing cable and the effective of ground stud, make connection device and the earth form equipotential, static is imported the earth, guarantee that equipment electrostatic grounding loop resistance meets the national safety standard regulation.The sun power that utilizes clean environment firendly in the environment is as the energy, and solar panel is to adopt epoxide-resin glue to be potted on the PCB solar battery sheet, absorbs sunlight and is converted to direct current, charges to rechargeable battery.Thereby make sun power electrostatic grounding alarm, overcast and rainy can the use as usual need not be laid electric line or be changed battery.Fully guarantee the supply of alarm power supply and then guarantee 24 hours round-the-clock online automatic detection of alarm.

The super low-power consumption microprocessor microcontroller MPU of this system all adopts IT series, and this single-chip microcomputer contains comparator configuration, is a kind of accurate comparer, can accurately compare grounding resistance, for the judgement of electrostatic potential provides convenience.System is based on continuous detecting connection device loop and ground terminal loop resistance value, be connected by top, ground connection clamp, ground clamp cable, earthing cable and the effective of ground stud, make connection device and the earth form equipotential, static is imported big ground mode, can carry out online detection the working point.The working point grounding resistance that set to need monitoring, and the working point grounding resistance is compared judgement by the built-in comparer of single-chip microcomputer, single-chip microcomputer and then judge whether to exceed standard and whether carry out on-the-spot sound and light alarm; When the working point grounding resistance exceeded standard, buzzer warning and LED alarm lamp were bright, when ground clamp fails to clamp the working point well, can send sound and light alarm too, so that the supvr in time takes appropriate measures, had avoided accident potential.
