Detailed description of the invention
The utility model provides a kind of liquid level gauge, below in conjunction with the accompanying drawings and detailed description of the invention, describes the utility model in detail:
As shown in Figure 1, a kind of liquid level gauge that the utility model provides, including measuring body 1, measure and be fixed with multiple floating-ball level switch 20 on the outer wall of body 1, floating-ball level switch 20 in the present embodiment is five, it is respectively the first floating-ball level switch 21, second floating-ball level switch 22, 3rd floating-ball level switch 23, 4th floating-ball level switch 24 and the 5th floating-ball level switch 25, measure and be fixed with the first floating-ball level switch 21 successively on the outer wall of body 1, second floating-ball level switch 22, 3rd floating-ball level switch 23, 4th floating-ball level switch 24 and the 5th floating-ball level switch 25.Distance between bottom first floating-ball level switch 21 and measurement body 1 is measure body 1 length 1/10th；Distance between bottom second floating-ball level switch 22 and measurement body 1 is measure body 1 length 1/4th；Distance between bottom 3rd floating-ball level switch 23 and measurement body 1 is measure body 1 length 1/2nd；Distance between bottom 4th floating-ball level switch 24 and measurement body 1 is measure body 1 length 3/4ths；5th floating-ball level switch 25 is positioned at the top measuring body 1.When water level rises to the position of the first floating-ball level switch 21, first floating-ball level switch 21 sends liquid level signal, then liquid level gauge display water level arrives 10%, when water level rises to the position of the second floating-ball level switch 22, then liquid level gauge display water level arrives 25%, when water level rises to the position of the 3rd floating-ball level switch 23, then liquid level gauge display water level arrives 50%, when water level rises to the position of the 4th floating-ball level switch 24, then liquid level gauge display water level arrives 75%, when water level rises to the position of the 5th floating-ball level switch 25, then liquid level gauge display water level arrives peak, now the alarm on liquid level gauge sends alarm signal.
As shown in Figure 2,3, first floating-ball level switch the 21, second floating-ball level switch the 22, the 3rd floating-ball level switch the 23, the 4th floating-ball level switch 24 and the 5th floating-ball level switch 25 are identical structure, for floating-ball level switch 20, floating-ball level switch 20 includes the first bearing 31 and the second bearing 32.First bearing 31 is provided with fork 41, the central authorities of fork 41 are articulated with on the first bearing 31, the left part of fork 41 is provided with boss torr 42, boss torr 42 be arranged over switch contact 43, the right part of fork 41 is provided with the first magnet 44, the right edge of fork 41 is provided with spring 45, and spring 45 is vertically fixedly connected on fork 41, and the weight of boss torr 42 is more than the weight of the first magnet 44.Second bearing 32 is provided with fly rod 51, the central authorities of fly rod 51 are articulated with on the second bearing 32, the left part of fly rod 51 is provided with the second magnet 52, second magnet 52 is positioned at the upside of the first magnet 44, and second the upper end of bottom and the first magnet 44 of magnet 52 be homopolarity, the right part of fly rod 51 is provided with ball float 53, and the weight of ball float 53 is more than the weight of the second magnet 52.
When water level rises, ball float 53 place end utilizes buoyancy gradually to rise, and the second magnet 52 place end declines gradually, utilizes homopolar-repulsion between magnet, will press under the first magnet 44 place end, and end rising in boss torr 42 place contacts with switch contact 43, sends liquid level signal；When the water level descends, ball float 53 place end sinks, now the second magnet 52 is apart from each other with the spacing of the first magnet 44, mutual expelling force between the two is less, now, is in the oppression state under the homopolar-repulsion power of the first magnet 44 at the second magnet 52 before the spring 45 on the right side of fork 41, owing to mutual expelling force reduces, the right side of fork 41 is pushed up by the elastic force of spring 45, and switch contact 43 separates with boss torr 42 then, and liquid level signal disappears.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, on the premise of creating design without departing from the utility model, it is also possible to making some deformation and improvement, these broadly fall into protection domain of the present utility model.
