Specific embodiment

The utility model is described further in the following with reference to the drawings and specific embodiments.

As depicted in figs. 1 and 2, liquid level device for detecting density provided in this embodiment, including fixing seat 10, liquid level buoy 20 With density float 30.

Fixing seat 10 has the slide opening 11 arranged vertically, it is preferred that seal closure 40 is fixedly connected in fixing seat 10, this is close Sealing cover 40 and slide opening 11 are coaxially arranged, and the lower end of seal closure 40 has outwardly projecting bulge loop 41, and fixing seat 10 then includes The seat of honour 14 of mutual cooperation connection and lower seat 12 and the sealing ring 13 between the seat of honour 14 and lower seat 12, bulge loop 41 are compacted Between sealing ring 43 and the upper surface of lower seat 12, the connection between seal closure 40 and fixing seat 10, certainly, slide opening are realized with this 11 are located on lower seat 12.In addition, seal closure 40 is preferably translucent cover, convenient for observing the height of liquid level buoy 20 and density float 30 Position, and then liquid level and density are judged, to estimate filling time and the adding amount of electrolyte or distilled water.

Liquid level buoy 20 includes the hollow stem 21 being interspersed in slide opening 11 and is fixedly connected on the hollow of 21 lower end of hollow stem Float 22, i.e. hollow stem 21 are arranged vertically.The inner cavity of hollow float 22 and the inner hole of hollow stem 21 are interconnected, and hollow The largest contours diameter of float 22 is greater than the diameter of slide opening 11, i.e. hollow float 22 is difficult to be inserted into slide opening 11, hollow stem 21 The one end of inner hole far from hollow float 22 is connected to outside.Fixing sleeve is equipped with indicating ring 23 on hollow stem 21, and indicating ring 23 is located at The top of fixing seat 10, and the outer diameter of indicating ring 23 is also greater than the diameter of slide opening 11 may insure that hollow stem 21 will not be from this way Deviate from slide opening 11.Indicating ring 23 is preferably dark ring, such as blue color circle, black ring or red ring, is observed convenient for user, and empty Core bar 21 is preferably transparent bar, convenient for observing density float 30.In addition, the upper end of hollow stem 21 is pierced by and wears from slide opening 11 It is inserted in seal closure 40.

In addition, in the present embodiment, the lower end of hollow float 22 has the opening being connected to its inner cavity, and liquid level buoy 20 is also Including the end cap 24 for being located at above-mentioned opening and being detachably connected with hollow float 22, restraining position ring block is arranged in the upper end of end cap 24 25, and end cap 24 offers through-hole 26 at the corresponding position in the space that is surrounded with stop collar 25.

Density float 30 includes the indicating arm 31 being interspersed in the inner hole of hollow stem 21 and is fixedly connected under indicating arm 31 The density block 32 at end, i.e. indicating arm 31 are also to arrange vertically.Indicating arm 31 is nontransparent bar, and the color and finger of indicating arm 31 Show that the color of ring 23 is different, the color of the two preferably also should not be similar, so that naked eyes can be distinguished intuitively.Density block 32 are located in the inner cavity of hollow float 22, specifically, density block 32 is located in the space that stop collar 25 is surrounded.Density block 32 Largest contours diameter is greater than the diameter of bore of hollow stem 21, and such density block 32 is difficult in the inner hole for penetrating hollow stem 21, realizes Limit function.In addition, density block 32 is preferably hollow density block.

In use, fixing seat 10 is fixedly connected on the shell or cover board of lead-acid accumulator, and make hollow float 22 It is suspended on the liquid level of electrolyte, and partial electrolyte liquid then passes through through-hole 26 and flows into the space that stop collar 25 is surrounded, so that Density block 32 is also immersed in electrolyte, and when electrolyte volume changes, the liquid level of electrolyte can also change therewith, into And reflected by liquid level buoy 20, likewise, the position of density block 32 also can be therewith when density of electrolyte changes Variation, and then reflected by density float 30.
