[0039] Among them, it further includes a control device. The control device includes a PLC processor and several control units.

The positioning module can be a GPS module or a Beidou positioning module and is used to determine the specific position of the well body 1.

[0040] Among them, as Figure 1 shown, a vertical support 7 is fixed on the inner bottom surface of the box body 2. The vertical support 7 is located between the air pump 5 and the single - coil pipe reel 3. The rotary joint 502 penetrates through the vertical support 7 and is rotationally matched with the vertical support 7 through a bearing or a bushing.

[0045] The working principle of the present utility model is as follows:

[0046] After installing the detection device in the well body 1, first confirm a starting point. The height between the starting point and the bottom surface of the well body 1 is h1. Repeatedly control the motor reducer 6 to lower the counterweight cone 401 multiple times, so that the encoder value corresponds to the moving distance of the counterweight cone 401. That is, by the encoder, confirm that the moving distance of the counterweight cone 401 is d1. Then, after stopping the machine, the height of the position of the counterweight cone 401 in the well body 1 is h2 = h1 - d1;

[0047] During actual use, when it is necessary to detect the liquid level height, first start the air pump 5. After the pressure detected by the pressure sensor 503 is stable, start the motor reducer 6 to control the single reel 3 to rotate, so as to unwind the metal hose 4. The metal hose 4 is straightened and lowered by the counterweight cone 401. The gas in the air pump 5 is discharged through the sleeve 301, the metal hose 4 and the one-way valve 402. When the bottom end of the metal hose 4 touches the water surface, the pressure sensor 503 will detect an increase in pressure. Record the encoder value at the moment of pressure change, and retrieve the d1 value corresponding to this value, then the liquid level height (i.e., h2) can be calculated;

[0048] The motor reducer 6 continues to operate, controlling the counterweight cone 401 to continue moving downward. When it touches the sludge layer, the pressure will change again, so that the height of the sludge layer can be calculated;

[0049] Finally, control the metal hose 4 to wind up through the motor reducer 6, and control the counterweight cone 401 to reset to the starting point.
