Abstract
The utility model discloses an explosion-proof starter composed of a motor and an electromagnetic engagement switch. The motor comprises a motor shell, a stator, a rotor, a main shaft, a positive wiring column, a negative wiring column, a front cover, and a rear cover. Junction surfaces of the motor shell and the front and rear covers employ explosion-proof junction surfaces. Encapsulated explosion-proof layers are arranged in gap positions among the stator, the motor shell, and the front and rear covers. An encapsulated insulated sealing structure is adopted in junction positions of the positive and negative wiring columns and the motor shell. The electromagnetic engagement switch comprises an electromagnetic engagement switch shell and an induction coil. The induction coil is provided with an encapsulated protective layer. The explosion-proof starter of the utility model is capable of preventing electric sparks, which are generated inside the motor and the electromagnetic engagement switch and brought by electrification of a vehicle body, from igniting external explosive dangerous gas, thereby realizing the safe operation under explosive gas environments and further guaranteeing the safety of field staff.
Description
Technical field
The utility model relates to explosion-proof fire fighting truck component technology field, relates in particular to a kind of explosion-proof starter.
Background technology
When explosion-proof fire fighting truck (vehicle) used in the dangerous place with a potential explosion operation, each electric component on vehicle and non-electric component all should be the explosion-proof parts that do not produce the hazards such as high temperature and (quiet) electric spark.Matching used starter on automobile is mechanical energy with the electric energy conversion of storage battery, drives the startup that the engine flywheel rotation realizes engine.Common starter is when wiring, usually adopt the minus earth form, if during the storage battery electric leakage, vehicle body is with charged, thereby the fire fighter may cause electric spark and ignite explosive gas atmosphere on every side when charged vehicle body operation, DC motor in starter and electromagnetism engage switch can produce electric spark in running also may ignite explosive gas atmosphere on every side, at present the domestic explosion-proof starter that can be used in explosive gas atmosphere that there is no.
The utility model content
The utility model provides a kind of explosion-proof starter that can use safely in explosive gas atmosphere.
realize that the technical scheme that above-mentioned purpose is taked is: a kind of explosion-proof starter, formed by motor and electromagnetism engage switch, wherein motor comprises electric machine casing, stator, rotor, main shaft, just, negative terminal and before, rear end cap, described electric machine casing with before, explosion-proof composition surface is adopted on the composition surface of rear end cap, before described stator and electric machine casing reach, position, space between rear end cap arranges the encapsulation explosion-proof layer, just described, negative terminal and described electric machine casing junction employing encapsulation insulation and sealing structure, described electromagnetism engage switch comprises electromagnetism engage switch housing and induction coil, described induction coil arranges the encapsulation overcoat.
The negative terminal of described motor is drawn outside described electric machine casing by wire, and is connected with power cathode.
Described encapsulation explosion-proof layer protrudes the iron core internal circular surfaces 1mm of described stator or more than 1mm, the gap between encapsulation explosion-proof layer and described rotor and main shaft is 5～10mm.
Described encapsulation explosion-proof layer and encapsulation overcoat are formed by explosion-proof clay encapsulation.
the beneficial effects of the utility model are: its motor adopts flame proof to process and has stopped the electric spark ignition extraneous explosion hazardous gas that motor interior produces, the electromagnetism engage switch adopts encapsulation to process and has stopped equally the inner electric spark ignition extraneous explosion hazardous gas that produces of electromagnetism engage switch, the starter wiring adopts double wire system to avoid the charged generation electric spark of also just having avoided of vehicle body, starter external cabling position prevents short-circuit conditions with explosion-proof clay sealing and causes spark, the utility model can safe operation in explosive gas atmosphere, thereby guaranteed Field Force's safety.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, explosion-proof starter 15 of the present utility model is comprised of motor and electromagnetism engage switch 13, is used for the startup of engine.Wherein motor comprises electric machine casing 4, stator 5, rotor 6, main shaft 7, positive and negative electrode binding post 1,2 and forward and backward end cap 3,8.Explosion-proof composition surface is adopted on described electric machine casing 4 and forward and backward end cap 3,8 composition surface, described positive and negative electrode binding post 1,2 and described electric machine casing 4 junctions adopt the encapsulation insulation and sealing structures, consist of thus flame-proof motor, the possibility of the extraneous explosion environment of stopping to ignite after the explosion risk gas in inner spark ignition housing.Position, space between described stator 5 and electric machine casing 4 and forward and backward end cap 3,8 arranges encapsulation explosion-proof layer 9, to reduce the inner space to reduce the energy of inside after blasting.For the validity that both guarantees that encapsulation explosion-proof layer 9 is explosion-proof, can guarantee again the normal operation of motor, described encapsulation explosion-proof layer 9 should protrude the iron core internal circular surfaces 1mm of described stator 5 or more than 1mm, the gap between encapsulation explosion-proof layer 9 and described rotor 6 and main shaft 7 should be controlled in 5～10mm scope.The connection of the power supply wiring of described motor has changed existing negative pole by the mode of connection of electric machine casing ground connection, the double wire system mode of connection that adopts the both positive and negative polarity wiring all directly to be connected with power supply, be about to negative terminal 2 and electric machine casing 4 independent, with wire, the negative pole of motor is drawn out to outside from the negative terminal of enclosure interior, the negative line of being connected with whole system connects.Described electromagnetism engage switch comprises electromagnetism engage switch housing 12 and induction coil 10, and described induction coil 10 arranges encapsulation overcoat 11.Described encapsulation explosion-proof layer 9 and encapsulation overcoat 11 can adopt explosion-proof clay encapsulation to form.
explosion-proof starter of the present utility model, its motor 1 adopts flame proof to process and has stopped the inner electric spark ignition extraneous explosion hazardous gas that produces of motor 1, electromagnetism engage switch 2 adopts encapsulation to process and has stopped equally the inner electric spark ignition extraneous explosion hazardous gas that produces of electromagnetism engage switch, the starter wiring adopts double wire system to avoid the charged generation electric spark of also just having avoided of vehicle body, starter external cabling position prevents short-circuit conditions with explosion-proof clay sealing and causes spark, the utility model can safe operation in explosive gas atmosphere, thereby guaranteed Field Force's safety.
