Description
Technical field
The utility model relates to oil level detection fields, and in particular to eliminate the oil level detecting device of tongue tube false alarm.
Background technique
Lubricating oil is widely used in each machine driven system as lubricant, is inevitably produced in its operational process
Raw loss, especially in the mechanical system of aviation aircraft, lubricating oil loss is more.In Machine Movement Process, lubricating oil is very few, meeting
Increase mechanical wear, moving component can be damaged when serious, causes mechanical breakdown.Lubricating oil is excessive, when machinery adjustment moves, will cause
Lubricating oil overflows, and has the danger of detonation if in the motion structure in sealing, thus monitor lubricating oil amount number be necessary.
Current more common lubricating oil liquid level alarm, wherein tongue tube is fixed in axis and with casting glue, magnetic
Steel is mounted in float, and how much float moves up and down with lubricating oil, when lubricating oil is reduced, when magnet steel is close to tongue tube, and tongue tube reed
It is attracted under the influence of a magnetic field, issues alarm signal.Therefore the position of tongue tube determines that the alarm point of product, tongue tube use
Casting glue is fixed, and method is simple, at low cost, is widely used.
In the magnetic fields principle of tongue tube, as shown in figure 3, the direction polarity NS of magnet steel is Y-direction, transported with magnet steel along Y-axis
It is dynamic consistent, at a distance from the magnet steel with X-axis on, there are three points, and dry spring to be made to generate switch motion, and one of alarm point is stronger, application
In use this point, in addition two o'clock is smaller, by adjusting magnet steel at a distance from X-axis, to avoid lesser two trigger points.But
In practice, especially in aviation field using constantly, due to using temperature higher, environment temperature need to reach -55 DEG C~200
DEG C, since reed can soften at high temperature in tongue tube, there are Multiple Dots Alarm Rules, issues false alarm phenomenon；In low temperature, according to
The low-temperature characteristics of magnet steel, magnetism can enhance, and will appear Multiple Dots Alarm Rules phenomenon, issue false alarm.
Utility model content
Technical problem to be solved in the utility model be existing oil level detecting device in the high temperature environment, the meeting of detection
It is easy to appear error, service efficiency is lower, and it is an object of the present invention to provide eliminate the oil level detecting device of tongue tube false alarm, solves high temperature
In environment the problem of the use of oil level detecting device.
The utility model is achieved through the following technical solutions:
The oil level detecting device for eliminating tongue tube false alarm, the inside including tongue tube, for placing tongue tube are cavity
Placed cavity, placed cavity opposite side on be arranged sliding axle, be provided on sliding axle along the float slided thereon and
Magnet steel in float, the interior bottom of placed cavity are provided with fixed block, and fluted, the upper and lower ends point of tongue tube are arranged on fixed block
It is not provided with the first fixed block and the second fixed block, the second fixed block is connected in groove, opening is provided with above placed cavity,

Further, when in use, the direction the polarity NS setting of magnet steel and sliding axle, i.e. Y-direction is vertical, after change for the present apparatus
Tongue tube characteristic as shown in Fig. 2, compared with existing tongue tube characteristic as shown in Figure 3, there are two alarms for present apparatus tool
Point, two trigger points are in the same size, can effectively avoid the generation of false alarm.
The present apparatus can effectively avoid the generation of false alarm phenomenon from working principle.The design of Y/XU-128 oil level signal device
When magnet steel be disposed vertically, magnetic direction is vertical with tongue tube, and tongue tube characteristic is the equal zone of action of two amplitudes, therefore
Product will not have false alarm generation.
Also, the present apparatus does not need that tongue tube is fixed using casting glue, when tongue tube uses casting glue in axis,
At high temperature since the casting glue coefficient of expansion is larger, so that the tongue tube in casting glue is generated biggish displacement, generate biggish ask
Topic: 1. product alarm point can vary widely, and keep product overproof；2. due to the heat of tongue tube and its connecting wire and casting glue
The coefficient of expansion is inconsistent, it may appear that the phenomenon that tongue tube extraction wire is pulled off is connected when applied at elevated temperature；3. if dry spring will be installed
The space of pipe is filled up with casting glue, at high temperature, can be generated very high pressure intracavitary, be will lead to showing for cavity explosion when serious
As occurring.
Therefore the present apparatus is by the way that tongue tube to be put into placed cavity from above placed cavity, and is fixed on the recessed of fixed block
In slot, therefore the present apparatus does not need to be fixed by casting glue, therefore will not cause error in the event of high temperatures, more effectively
Elimination tongue tube false alarm the case where occur, be more advantageous to long-time service.
Preferably, eliminate tongue tube false alarm oil level detecting device, the tongue tube in the grooves when, tongue tube institute
It overlaps in the perpendicular bisector of straight line and placed cavity.Tongue tube is located on the perpendicular bisector of placed cavity, thus to the magnet steel on both sides it
Between distance be identical, and then be more advantageous to tongue tube detection accuracy, be more convenient for being used for a long time.
Specifically, eliminating the oil level detecting device of tongue tube false alarm, the upper end of first fixed block and opening are opposite
Place is provided with little groove, and fixed link is connected in little groove, and the side of second fixed block is provided with external screw thread, sets in groove
It is equipped with internal screw thread corresponding with external screw thread, the second fixed block is connected through a screw thread with groove, when tongue tube is put into groove,
Tongue tube is put into placed cavity by fixed link, is threadedly coupled the second fixed block with groove by rotating fixing rod.
It, then will by fixed link by being connected and fixed bar in little groove when tongue tube being placed in placed cavity again
Tongue tube is placed in placed cavity together, and when fixed link is put into when placed cavity, tongue tube is located in the placement cavity, then passes through rotation
Turn fixed link the second fixed block rotation of tongue tube lower end is connected in groove, and then tongue tube is fixedly connected,
Under the drive of fixed link in a groove by tongue tube rotation connection, after rotation connection, fixed link is taken out by external force, is finally made
Tongue tube stays in placed cavity, is more convenient for being used for a long time.
Preferably, the oil level detecting device of tongue tube false alarm is eliminated, is provided with rubber layer in the little groove.Small recessed
Rubber layer is provided in slot, therefore being fixedly connected between fixed link and little groove is even closer, is more advantageous to and is fixedly connected.
Preferably, the oil level detecting device for eliminating tongue tube false alarm, between the perpendicular bisector and magnet steel of the placed cavity
Distance is 1cm.The distance between magnet steel and tongue tube are arranged in 1cm, not only detect more accurate and will not influence use.
