[0023] Embodiment 1:

[0024] like Figure 1 As shown, an adjustable probe for a sludge interface meter is arranged in a sludge tank 1, comprising a detection head 12 perpendicular to the bottom wall of the sludge tank 1, a U-shaped limiting tube 2 and an adjustment component for adjusting the height of the detection head 12 in the sludge tank 1.

[0025] The sludge interface meter of this embodiment uses an adjustable probe, a limit tube 2 and a guide rod 11, so that the detection head 12 perpendicular to the bottom wall of the sludge tank 1 can be adjusted in height along the guide rod 11 to prevent the detection head 12 from moving with the flow of sewage and prevent the detection head 12 from being unable to be perpendicular to the bottom wall of the sludge tank 1, thereby enabling the detection head 12 to detect the true thickness of the sludge layer and improve the detection accuracy.

[0026] like Figure 2-3, one end of the limiting tube 2 is fixed to the top of the sludge tank 1 through a fixing assembly, and the other end of the limiting tube 2 passes through the top wall of the sludge tank 1. A guide hole 6 is provided at one end of the limiting tube 2 inserted into the sludge tank 1; the fixing assembly includes a fixing plate 4 and a sleeve 3 arranged on the fixing plate 4, the fixing plate 4 is fixed to the top of the sludge tank 1 through a fixing bolt 5, and the sleeve 3 is sleeved on the end of the limiting tube 2; the adjusting assembly includes a plurality of guide rods 11 fixed to one end of the limiting tube 2 inserted into the sludge tank 1 and an adjusting block 10 penetrated on the guide rods 11, the detection head 12 is arranged on the top of the adjusting block 10, and the adjusting block 10 is connected to the power unit, and the power unit is arranged on the top of the sludge tank 1 to drive the adjusting block 10 to move along the guide rods 11.

[0027] In actual use, first set the fixing assembly on the sludge tank 1, fix the fixing plate 4 to the top of the sludge tank 1 by the fixing bolts 5, then cooperate with the adjusting block 10 on the guide rod 11, and then connect the connecting line 9 to the adjusting block 10 and pass through the guide hole 6 on the limiting tube 2 and then wrap around the rotating wheel 8, insert one end of the limiting tube 2 into the sleeve 3 for limitation, and the other end passes through the top wall of the sludge tank 1, and then adjust the height of the adjusting block 10 in the sludge tank 1 by controlling the working state of the motor 7 to prevent the detection head 12 from moving with the flow of sewage and prevent the detection head 12 from being unable to be perpendicular to the bottom wall of the sludge tank 1, detect the distance between the detection head 12 and the sludge interface and the distance between the bottom wall of the sludge tank 1, so as to detect the thickness of the sludge layer.

[0028] The power unit includes a motor 7 fixed to the top of the sludge tank 1 and a rotating wheel 8 driven by the motor 7 . A connecting wire 9 is wound around the rotating wheel 8 . The end of the connecting wire 9 away from the rotating wheel 8 passes through the guide hole 6 and is fixed to the adjustment block 10 .

[0029] A roller is provided at the top of the wall of the guide hole 6; when adjusting the height of the detection head 12, the connecting wire 9 needs to be retracted and released, so the connecting wire 9 will generate sliding friction with the top of the wall of the guide hole 6, causing the connecting wire 9 to wear quickly. After the roller is provided, the sliding friction can be converted into roller friction, thereby reducing friction, thereby reducing the wear speed of the connecting wire 9, and improving the service life of the connecting wire 9.

[0030] A retaining ring 13 is fixed at the bottom of the guide rod 11, and a through hole is provided in the middle of the retaining ring 13; the setting of the retaining ring 13 can prevent the adjusting block 10 from falling off the guide rod 11 with the detection head 12 when the adjusting block 10 falls quickly, and the setting of the through hole can be avoided to accommodate the detection head 12, so as to prevent the detection head 12 from directly hitting the retaining ring 13 and being damaged when the adjusting block 10 falls quickly.

[0031] Counterweight blocks 14 are provided on both sides of the adjustment block 10; the setting of the counterweight blocks 14 can increase the gravity of the adjustment block 10, prevent the adjustment block 10 from being pushed by the upward-flowing sewage and causing a height change, thereby improving the detection accuracy.

[0032] The above description is only a preferred implementation mode of the present invention, and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
