Description
Technical field
The utility model belongs to the protective device of vehicle-carried mobile facilities such as truck tanker, pressure car, particularly a kind of vehicle-mounted protective device that has static elimination and lightning protection function concurrently.
Background technology
MOVING STRUCTURE such as truck tanker, pressure car is in transportation, and meetings such as oil product and gas are violent rocking, collide, rub in tank body, will produce very high electrostatic potential like this, and then produces spark discharge; Thundery sky, under the effect of the electrostatic field that forms between thundercloud and the earth, MOVING STRUCTUREs such as truck tanker, pressure car will face bigger static to be threatened, if be struck by lightning, consequence is hardly imaginable especially, the accident that car is ruined people's wound or car crash happens occasionally.Not only in transportation, can produce static in fact, in processes such as loading and unloading, clear jar, also very easily produce static,, also can cause disastrous accidents such as blast if deal with improperly.Thunder and lightning and static hazard have become the main threat that MOVING STRUCTUREs such as truck tanker, pressure car face.
In order to reduce the threat of static, prior art generally is to hang iron chains on car body, by iron chains the electrostatic leakage of MOVING STRUCTUREs such as truck tanker, pressure car is gone into ground.But, owing to iron chains and ground-surface friction in the process of moving is easy to generate spark, therefore the technical scheme of iron chains has appearred replacing with conductive rubber.Yet all there is the problem of bad earth in above-mentioned two kinds of measures in MOVING STRUCTURE driving process such as truck tanker, pressure car, cause static fully not release, and make the vehicle-carried mobile facility still exist static to threaten.About lightning protection, do not see that as yet the vehicle-carried mobile facility is provided with the report of thunderstorm electricity protective device.
Summary of the invention

The principle of work of vehicle-mounted protective device described in the utility model: vehicle-mounted protective device described in the utility model is installed on the vehicle-carried mobile facility, when car body faces the static threat, structure design by this device is based upon the electric potential difference of car body and the earth between induction tube and the discharge brush, as long as at this moment the conductive strips in this device are contacted with ground, the electric charge of the earth will be transferred on the discharge brush, on discharge brush, form and the opposite electric charge of induction tube, cause between discharge brush and the induction tube and form certain difference of potential, bunch discharge takes place, neutralize Partial charge, magnitude of voltage is reduced in the scope of a safety; If static charge buildup is very fast, electrostatic potential raises rapidly, and gas-discharge tube will puncture, and electrostatic potential is clamped down on rapidly in the range of voltage values of safety.In the thunder and lightning generation evolution, when stepped leader front end during near ground, enter the court at outstanding objects such as ground-surface natural tip or high-lager buildings and will bring out one or several upward leader when acquiring a certain degree by force, produce connection procedure (promptly launch aing surprise attack) thus, be before truck tanker is struck by lightning, the field intensity that must satisfy certain point of truck tanker top reaches certain intensity and just can be struck by lightning, vehicle-mounted protective device described in the utility model has effectively limited the accumulation of electrostatic charge on the vehicle-carried mobile facility by bunch discharge, make vehicle-carried mobile facility top be difficult to reach the field intensity that produces upward leader, thereby reduced the thunderstruck probability of vehicle-carried mobile facility.
Vehicle-mounted protective device described in the utility model also is provided with dual polarity electrostatic and induces conductor and insulating bushing, described insulating bushing is installed on the conductive support and between pin top and last insulating cove, described dual polarity electrostatic is induced the conductor suit and is fixed on the insulating bushing.When electronegative thundercloud during near vehicle-mounted protective device described in the utility model, pin top absorbing component and dual polarity electrostatic induce conductor upper surface and discharge brush all to induce positive charge, dual polarity electrostatic induces the conductor lower surface to induce negative charge, the induction drum outer wall induces positive charge, induction tube inwall induces negative charge, therefore can strengthen responding to tube electric field on every side, promote surrounding air generation ionization.The thundercloud of positively charged near the time, the charge polarity that above-mentioned each member (pin top absorbing component, dual polarity electrostatic are induced conductor, discharge brush, induction tube) is induced and electronegative thundercloud near the time opposite.
For structure is more rationally assembled with being convenient to, the utility model has also been taked following technical measures:
1, be provided with metal washer, described metal washer is installed in down in the set annular groove of insulating cove, and the lower end of described induction tube is installed on the metal washer, and an end of described gas-discharge tube is connected with metal washer, and its other end is connected with conductive support.
2, conductive support is made up of strut bar and pedestal, and strut bar is installed on the pedestal.
3, be provided with insulating base, described insulating base is positioned under the pedestal of conductive support.
The utlity model has following beneficial effect:
1, vehicle-mounted protective device described in the utility model has effectively limited the accumulation of static charge on the vehicle-carried mobile facility by bunch discharge, electrostatic potential on the vehicle-carried mobile facility is remained in the safe scope, efficiently solve the static threat that the vehicle-carried mobile facility is faced.
