[0006] Furthermore, a scale groove is provided on the surface of the magnetic flap.

[0007] Furthermore, the diameter of the buoy is smaller than the diameter of the through hole.

[0008] Furthermore, the upper and lower end surfaces of the two slide rails are fixedly connected with a limit shaft, and the top of the limit shaft is arranged above the slide block.

[0009] Furthermore, the magnetic flap is in a hollow cylindrical shape, and the opening groove faces downward.

[0010] Furthermore, a flap indicator is provided on the magnetic flap, and the flap indicator is located on one side of the scale wire groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention solves the problem that when the measured medium contains more impurities, the impurities contained in the float inside the magnetic flap liquid level meter are easily adsorbed on the surface of the float during actual use, increasing the weight and resistance of the float, causing the float to deviate during movement, thereby affecting the accuracy of liquid level measurement, through the clearance cooperation of the arranged magnetic flap, slide rail, top cover, connecting flange, slider, floating plate, through hole, traction rope, buoy, limit shaft and scale wire groove.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1

[0020] See also Figure 1 to Figure 2 The present invention provides a technical solution: a magnetic flap level gauge, comprising a magnetic flap 1, the upper and lower end surfaces of the magnetic flap 1 are fixedly connected with a top cover 3 and a connecting flange 4 by bolts in sequence, the inner cavity side walls of the magnetic flap 1 are fixedly connected with slide rails 6, a floating plate 9 is arranged near the middle of one side of the two slide rails 6, the two side walls of the floating plate 9 are fixedly connected with sliders 7, the two sliders 7 are in sliding contact with the two slide rails 6 respectively, a through hole 10 is opened in the middle of the floating plate 9, a traction rope 11 is arranged at the middle position of the bottom of the top cover 3, the traction rope 11 passes through the inner cavity of the through hole 10 and is fixedly connected with a buoy 5 at the bottom;

[0021] Specifically, the sliding process can be realized by utilizing the setting of the slider 7 and the slide rail 6, thereby conveniently driving the floating plate 9 to move upward. At the same time, the setting of the connecting flange 4 and the top cover 3 can improve the stability of the overall structure. The setting of the traction rope 11 can provide guidance for the buoy 5 to prevent the buoy 5 from shifting.

[0022] Wherein: the surface of the magnetic flap 1 is provided with a scale line groove 2;

[0023] Specifically, the height of the liquid level rise can be detected by the scale groove 2 arranged on the surface of the magnetic flap 1.

[0024] Wherein: the diameter of the buoy 5 is smaller than the diameter of the through hole 10;

[0025] Specifically, by setting the diameter of the buoy 5 to be smaller than the diameter of the through hole 10 , the buoy 5 can pass through the through hole 10 , thereby achieving an effect of increasing buoyancy.

[0026] Wherein: the upper and lower end surfaces of the two slide rails 6 are fixedly connected with a limit shaft 8, and the top of the limit shaft 8 is arranged above the slide block 7;

[0027] Specifically, the limiting shafts 8 arranged on the upper and lower end surfaces of the slide rail 6 can limit the slider 7 internally connected to the slide rail 6 to prevent the floating plate 9 from separating from the slide rail 6 .

[0028] Wherein: the magnetic flap 1 is in a hollow cylindrical shape, and the opening groove faces downward.

[0029] Wherein: a flip indicator is provided on the magnetic flip plate 1, and the flip indicator is located on one side of the scale wire groove 2;

[0030] Specifically, the flap indicator provided on the magnetic flap 1 can facilitate intuitive detection of the height of the liquid level rise and make an assessment using the indicator.

[0031] In the present embodiment, the buoyancy can be increased by utilizing the buoy 5 and the traction rope 11 to penetrate the through hole 10. The buoyancy effect of the floating plate 9 can drive the sliders 7 on both sides to realize the sliding displacement process of the slide rails 6 set on both sides, thereby increasing the buoyancy of the buoy 5, so that the buoy 5 will not be offset during the movement, thereby improving the stability of the liquid level measurement.

[0032] Example 2

[0033] See also Figure 3 The difference from Example 1 is that at this time, no through hole 10 is provided on the surface of the floating plate 9, and the top of the traction rope 11 is connected to the floating plate 9.

[0034] In this embodiment, when in use, the buoy 5 is damaged by external interference and cannot be moved upward. At this time, the traction rope 11 is connected to the floating plate 9, and the slider 7 and the slide rail 6 on both sides of the floating plate 9 can slide and utilize the buoyancy effect to move the buoy 5 with the damaged bottom upward, thereby achieving the floating effect and ensuring the accurate liquid level measurement.

[0035] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
