Abstract
The utility model is suitable for the explosion protection of the electric parts of electronic devices and robots working under the condition with combustible and explosible substance and powder dust. The explosion protection body is made of an inflatable interlayer made from rubber cloth. A pressure comparing controller, an electronic device and an inverter power supply are arranged in the explosion protection, and when the air pressure in the interlayer made of rubber cloth is lost or the signal measured by a sensor is larger than the given value, the pressure comparing controller makes action, cuts the power supply and sends out a signal and a warning. The utility model has the advantages of simple structure and convenient operation.
Description
The utility model relates to a kind of explosion-protection equipment, is applicable under the inflammable and explosive environment electric part explosion-proof of the electronic device of work and robot and reports to the police.
At present, the electronic device of working in inflammable and explosive environment does not still have explosion-proof preferably and the warning measure, and patent of invention 85106744.1 has proposed explosion-proof scheme, and it is configured to rigid structure, more complicated.
The purpose of this utility model provides the explosion-protection equipment of the electrical appliance part of a kind of electronic device that uses and robot in inflammable and explosive environment.
Content of the present utility model is by the explosion-protection equipment body, compositions such as pressure comparison controller and inverter, the wall of explosion-protection equipment by the rubberized fabric interlayer make, the centre can charge into air, the inverter of pressure comparison controller, electronic device and power supply all is contained in the explosion-protection equipment.When the air decompression in the interlayer of explosion-protection equipment, pressure ratio is than controller action, and the Hall element control circuit disconnects, and cuts off the electronic device power supply.
The utility model can use electronic device under flammable explosive gas environment and dust condition, and can show or give the newspaper dangerous situation.
Description of drawings:
Fig. 1 is the sectional axonometric drawing of explosion-protection equipment.
Fig. 2 is a pressure control comparer sectional view.
Fig. 4 is the inverter schematic diagram.
Fig. 5 is handled leather spectacle case stereographic map.
1 explosion-protection equipment end face zip; 2 rubber glovess; 3 nexine zips; 4 outer zips; 5 sealing gland pads; 6 pressure chambers; 7 do not have the chamber of pressure; 8 rubber films; 9 pressure springs; 10 Hall element control circuits; 11 magnet steel; 12 pressure guiding valves; 19 zips; 20 leather spectacle cases; 21 handles.
Below in conjunction with description of drawings the utility model embodiment, the explosion-protection equipment wall is pressed into the rubberized fabric interlayer by the rubber of anti-combustion skin through particular manufacturing craft, can charge into air in the middle of it, the explosion-protection equipment top is provided with two- layer zip 3,4 in innner and outer and sealing gland pad 5, one end top of explosion-protection equipment is provided with the fiberglass observation panel, the bottom is provided with the rubber gloves 2 of operating instrument, and the gloves outside is provided with zip 1; Inverter and pressure comparison controller are installed in the bottom of explosion-protection equipment.During work, at first the inversion system to the charge in batteries inverter of explosion-protection equipment is converted to the state of charging the battery automatically, and in charging finished, can pack detecting instrument into explosion-protection equipment, its top nexine zip 3 closed, the sealing gland of packing into pad 5, outer zip 4 again closes; At this moment can be to explosion-protection equipment interlayer inflation, because the pressurising chamber of pressure comparer is communicated with by rubber hose with the interlayer of explosion-protection equipment, when air pressure reaches setting value; The automatic energized of Hall element control circuit, inflation should be no inflammable, explosive and do not have in the environment of flue dust and carry out.When the gas decompression in the explosion-protection equipment interlayer, the outage of Hall element control circuit, the instrument outage is with the danger of avoiding blasting.When the temperature of packing into, pressure, dust sensor, one-chip computer and light emitting diode and alarm, sensor is sent the measured signal more than or equal to its setting value into one-chip computer, lights corresponding light emitting diode automatically; Open alarm.For easy to carry, explosion-protection equipment can be loaded in the leather system spectacle case 20 that has handle 21 and zip 19.
Claims (1)
1, a kind of by the explosion-protection equipment body, the explosion-protection equipment that pressure comparison controller and inverter are formed is characterized in that the explosion-protection equipment body made by the rubberized fabric interlayer that the centre can charge into air; The inverter of pressure comparison controller, the electronic device of going into the well and the power supply of monitoring explosion-protection equipment interlayer internal pressure situation all is contained in the explosion-protection equipment.
