Description

Naval vessel hatch door magnetic switch

The utility model relates to a kind of naval vessel on-deck darkening or cabin door open and close state and shows, particularly by the switch of lights in the hatch door control cabinet.

Door-down switch is made up of hatch door displacement sensing and control light switch, previous this switch is promoted the push rod of door switch by hatch door when hatch door is closed, promote the break of contact lamp power by push rod again, though simple, in the use of reality, also there is such problem, because it is stressed bigger, the machinery push rod is yielding, and the contact is also fragile, and the installation position of door switch is subject to the seawater etch again and corrosion, darkening was lost efficacy, also influence the insulating power of supply network.

The purpose of this utility model is that a kind of magnet controlled door-down switch will be provided, when magnetic inducing body other when being toward or away from Hall effect sensing body to certain distance, promptly finish switch motion, when the hatch door of darkening is closed, controlled lamp is in the electrified light emitting state, and opening hatch door, but displacement is also little, just before light is revealed as yet, lights are extinguished, in need not darkening, the magnetic control door switch can be removed control, removing the control state, no matter hatch door is opened still and is closed, and it is luminous all can not influence in the cabin electric light.

Another new purpose of this practicality is to provide a kind of state of cabin door open and close to show.

The purpose of this utility model is achieved in that at the suitable position of the hatch door that needs darkening or state to show installs a Hall transducer, this sensor can be unitized, be that the inducing body is fixed on the elastic push rod of main body, by the hall sensing body relative displacement of magnet steel in main body on the promotion of the steel body collision block on the hatch door elastic push rod, also can be split type, promptly do relative displacement with the closing of hall sensing body root a tree name hatch door on being loaded on doorframe by the inducing body that is loaded on the hatch door, the displacement of the two all can make magnetic field change and cause the variation of Hall voltage, this electromotive force produces a voltage signal through the Hall integration member, controls the driving circuit of controlled lamp or the analog switch amount output that shows as state by it.As seen the utility model comprises input power supply, switch circuit power supply, removes control switch, Hall transducer and driver element, and they connect mutually with circuit successively, and the close loop control circuit structure that joins end to end and form a controlled lamp.

The utility model is because the inductive means between hatch door and doorframe adopts non-contact contact form, switch life is long, the sensing sensitivity, antijamming capability is strong, comformability to the hatch door linear deformation is good, and external form is small and exquisite, uses reliable and secure, can hold shock-resistant, vibration, damp and hot harsh environment, can be applicable to the different parts that the naval vessel needs position sensing.

Concrete structure of the present utility model provides with following embodiment and accompanying drawing thereof.

Fig. 1 is a circuit basic structure block diagram of the present utility model.

Fig. 2 is the hatch door installation form of sensor of the present utility model as integral type.

Fig. 3 is that sensor of the present utility model is as split type hatch door installation form.

Fig. 4 is that the utility model is controlled controlled lamp when being used in two hatch doors, dual power supply or as the electrical schematic diagram of passive contact output.

Below in conjunction with description of drawings service condition of the present utility model.

In the accompanying drawing, 1 expression input power supply, it be normally import power supply 2 ' and emergent input power supply 2 or combination, the controlled lamp of 3 expression dimouts or the status display unit of cabin door open and close, 4 expression switch circuit power supplys, the control switch is removed in 5 expressions, 6 expression Hall transducers, 7 expression driver elements, the inducing body of 8 expression Hall transducers, the sensing body of 9 expression Hall transducers, 10 expression Hall transducers are the mounting seat of integral structure, the signal cable extension of 11 expression sensing bodies, the elastic push rod of 12 expression integral sensors, 13 expressions are fixed on the steel body collision block on the hatch door, 14 expression hatch doors, 15 expression doorframes, 16 expression bulkheads, the angle steel of the sensing body and function of the fixing split type sensor of 17 expressions, the 18th, check screw, the 19th, the watertight rubber of hatch door.

The utility model comprises Hall transducer 6, driving circuit 7, the switch circuit power supply 4 that mainly is made of inducing body 8 and sensing body 9, removes control switch 5, removes control switch 5 among the figure and is in the control position.

By implementing Fig. 1, Fig. 2, Fig. 3, move along the direction of arrow at hatch door 14, be fixed on the inducing body 8 that the collision block 13 on the hatch door 14 promotes on the elastic push rod 12, or the inducing body 8 that moves with hatch door 14, make relative displacement to hall sensing body 9, during to certain distance, under the effect in magnetic field, Hall transducer 6 is promptly to driver element 7 outputs one voltage signal, under the effect of driver element 7, controlled lamp 3 energized 1 and luminous are in the moment of opening hatch door, course of action is just in time opposite, controlled lamp 3 loses power supply 1, and lights extinguish, and satisfies the requirement of darkening, be in when removing controlled position removing control switch 5, controlled lamp 3 is uncontrolled.

By Fig. 1, Fig. 4, the concrete working process of embodiment is described, among Fig. 4, normal input power supply 2 ' be to constitute through voltage transformer B, rectifier ZL by 220 volts of power supplys, emergency source of electrical power 2 then passes through dropping resistor R4 by storage battery, through isolation diode V6 input switching circuit power supply 4, power supply 4 mainly is made of integrated package 7812 again, and this power supply 4 is supplied with Hall transducer 6 and driver element 7 through removing control switch 5.When arbitrary hatch door 14 of two hatch doors is opened, the H1 of sensing body 9 or H2 will be output as high potential state, make driving aerotron V1 conducting in the driver element 7 by diode V3 or V4, carry out relay J 1, J2 adhesive, disconnect the normally closed contact J1-1 and the J2-1 of the controlled lamp 3 of control, make controlled lamp 3 dead electricity and extinguish.Only all shut, or when removing control switch 5 and disconnecting, make controlled lamp 3 luminous at two hatch doors.Simultaneously, relay J 1, J2 can outwards export the passive switch signal by contact, or outwards export analog switch amount signal by H1, H2, show that as the hatch door state V5 is a switch circuit work indication light-emitting diode.
