When the filter plate 104 is blocked in the long-time use process, the cleaning frame 109 is pressed, and when the cleaning frame 109 slides, the cleaning needle 111 is driven to be inserted into the hole of the filter plate 104, so that the filter plate 104 is cleaned, the hole on the filter plate 104 is dredged, and the blockage is prevented; elastic strip 105 has elasticity, and filter 104 passes through elastic strip 105 card in the annular groove of bar draw-in groove 103, through pressing elastic strip 105, makes elastic strip 105 slide on bar draw-in groove 103, can dismantle filter 104 get off, is convenient for change filter 104.
When the liquid pressure in the measured container changes, the pressure in the liquid level meter also changes, normally, after the liquid enters the measuring pipe 101, because of the principle of the communicating vessel, the pressures on the left side and the right side are the same, the buoyancy of the liquid drives the magnetic floater 201 to ascend, and the liquid height is displayed through the graduator 106, at the moment, the liquid level height of the measured liquid container is the same as the liquid level height in the measuring pipe 101, and the graduator 106 displays the liquid level scales in a normal state.
During normal measurement, when the magnetic floater 201 rises along with liquid, the clockwork spring 228 is stretched, the steel wire rope 202 on the winding rod 230 is completely straightened, when the measurement is stopped and no liquid exists in the measurement pipe 101, the magnetic floater 201 descends, the clockwork spring 228 is compressed by the reverse acting force on the clockwork spring 228 at the moment, the winding rod 230 is driven to rotate, the steel wire rope 202 is wound on the winding rod 230, and the winding is completed; the prior art is used in this section.
If the liquid level meter is adjusted or if the measured liquid level is too high and the height of the magnetic turning plate liquid level meter is limited, the liquid level meter needs to be adjusted in proportion and displayed as if the liquid level meter is scaled in an equal way; that is, the weight of the magnetic float 201 is increased, and the height ratio of the magnetic float 201 rising is reduced.
The initial state of the steel wire rope 202 is coiled on the winding rod 230, when liquid enters the measuring tube 101, the winding rod 230 slowly releases the steel wire rope 202 due to the buoyancy of the liquid, the magnetic floater 201 ascends, the switch knob 207 is manually rotated at the moment, the switch knob 207 is rotated to drive the pinion 214 to rotate, the pinion 214 drives the large gear ring 216 to rotate, so that the inner disc 215 rotates, the inner disc 215 drives the supporting plate and the weight block to rotate together, when three groups of first counterweight stacks 225 in the weight block rotate to the horizontal groove 212, the arc-shaped protruding strips 229 are clamped on the connecting plate 211 to drive the connecting plate 211 to slide, the floating height of the magnetic floater 201 can be reduced, at the moment, scales are displayed through the graduating device 106, and the first counterweight stacks 225 are provided with good weights, so that the height of the magnetic floater 201 can be reduced.
Meanwhile, the switch knob 207 can be rotated again to give a larger downward pulling force to the magnetic floater 201, the inner disc 215 is rotated to clamp the arc-shaped protruding strips 229 in the second weight stack 226 into the horizontal grooves 212, and the magnetic floater 201 can be driven to descend again through the connecting plate 211, because the second weight stack 226 is heavier than the first weight stack 225, and the liquid level is displayed again through the graduator 106.
From this, through setting up different weight pieces, can give the different weight of magnetic float 201, adjust the rise height of magnetic float 201 to the adjustment proportion shows the liquid level height, reaches the measuring purpose.
Due to the arrangement of the internal gear ring 213 and the internal gear structure 221, the switch knob 207 can only rotate in one direction, and the magnetic floater 201 is prevented from being controlled by the reverse rotation of the switch knob 207; meanwhile, sewage in the measuring pipe 101 can be discharged from the sewage discharge pipe 208 by twisting the sewage discharge valve 209; the invention can also disassemble the adjusting mechanism 2, so that the measuring pipe 101 can be cleaned conveniently, and the round platform 205 can be disassembled from the bottom of the measuring pipe 101 by twisting the screw 204 and then rotating the fixing frame 203, so that the measuring pipe 101 can be cleaned.
