Abstract
The utility model provides an immersion alarm sensor comprising an iron rod, a permanent magnet, a Hall semiconductor element and an output control circuit. The permanent magnet is of a non-closed ring structure and has an opening. The iron rod is movably arranged in space surrounded by the permanent magnet. The Hall semiconductor element is arranged at the opening of the permanent magnet and is connected with the output control circuit. The immersion alarm sensor can replace boat immersion alarm sensors of all existing types, and is simple in structure, convenient to maintain and low in cost.
Description
Technical field
The utility model relates to a kind of sensor automation field.
Background technology
At present, each model ship ship immersion alarm sensor, due to producer's blockade on new techniques, cannot place under repair, and can only wholely renew, and is unfavorable for maintenance support; And this magnetic control door switch is expensive, and the Buying Cycle is long, cause the problem such as repair cost rising, repair cycle prolongation.In view of above reason, in order to ensure the repair cycle, to control repair cost and be convenient to use from now on and keep in repair, can improve again under the stability of this equipment operation and the prerequisite of reliability this equipment is researched and developed to repacking not changing original performance state.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of immersion alarm sensor, replaces existing each model ship ship immersion alarm sensor, simple in structure, is convenient to maintenance, reduces costs.
The utility model is achieved in that a kind of immersion alarm sensor, comprise iron plate circle, permanent magnet ball float, Hall semiconductor element and output control circuit, the loop configuration that described iron plate circle is non-closure, and there is an opening, described permanent magnet ball float and be placed in movably in the space that iron plate corral becomes, described Hall semiconductor element is located at the opening part of permanent magnet and connects described output control circuit.
Further, described output control circuit comprises power amplifier, resistance R 1, R2, R3 and R4, two output terminals of described Hall semiconductor element connect respectively the output terminal of described power amplifier by R1, R2, the two ends of described R3 are connected to an input end and the ground connection of described power amplifier, and the two ends of described R4 are connected to another input end of described power amplifier and the output terminal of described power amplifier.
Further, described iron plate circle is the uniform iron plate circle of material.
The utility model has the advantage of: immersion alarm sensor of the present utility model, replace existing each model ship ship immersion alarm sensor, simple in structure, be convenient to maintenance, reduce costs.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model.
Embodiment
Refer to shown in Fig. 1, the utility model immersion alarm sensor, comprise iron plate circle 1, permanent magnet ball float 2, Hall semiconductor element 3 and output control circuit 4, the loop configuration that described iron plate circle 1 is non-closure, and there is an opening 11, described permanent magnet ball float 2 and be placed in movably in the space that iron plate circle 1 surrounds, described Hall semiconductor element 3 is located at the opening part 11 of iron plate circle 1 and connects described output control circuit 4.
Described output control circuit 4 comprises power amplifier 41, resistance R 1, R2, R3 and R4, two output terminals of described Hall semiconductor element 3 connect respectively the output terminal of described power amplifier 41 by R1, R2, the two ends of described R3 are connected to an input end (input end in the same way+) and the ground connection of described power amplifier 41, and the two ends of described R4 are connected to another input end (incorgruous input end-) of described power amplifier 41 and the output terminal of described power amplifier 41.So, the output signal of Hall semiconductor element 3 can obtain after described power amplifier 41 amplifies exporting again.
Described iron plate circle 1 is the uniform iron plate circle of material.
Principle of work of the present utility model is: by permanent magnet ball float 2 in the interior motion of iron plate circle 1, the magnetic field producing makes the two ends of Hall semiconductor element 3 produce potential difference (PD), when the input end magnetic induction degree of Hall semiconductor element 3 acquires a certain degree, the trigger of Hall semiconductor element 3 inside overturns, the output level state of Hall semiconductor element 3 is upset thereupon also, the normally closed signal of output terminal disconnects, and reaches thus the effect of immersion alarm sensor.Thereby replace existing each model ship ship immersion alarm sensor, and simple in structure, be convenient to maintenance, reduce use cost.
Although more than described embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; instead of for the restriction to scope of the present utility model; those of ordinary skill in the art are in equivalent modification and the variation done according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
