In the use process, the water is discharged at the position of the flushing pipe 10 to spray and wash the dredging block 310, so that the residue of floating matters is prevented, and when the liquid level falls back to the position below the plane of the platform 12, the driving motor 232 is turned off; meanwhile, if the liquid level of the leachate continuously rises, when the first ultrasonic measuring instrument 102 monitors that the liquid level is too high, a signal is sent to the connected PLC controller, and the PLC controller sends a signal to the alarm device, so that early warning is fast and timely, and the leachate is prevented from overflowing.

Specifically, as shown in fig. 18 to 29, two groups of traction ropes 901 extend from the winch 90 first, the left traction rope 901 and the right traction rope 901 sequentially pass through the fourth fixing portion 9325 and the seventh fixing portion 944 from top to bottom, then are bent upwards at the lower end of the outer side of the end measuring cylinder 94, and sequentially pass through the sixth fixing portion 943, the third fixing portion 9324, the fifth fixing portion 9334, the second fixing portion 9314 and the first fixing portion 923 from bottom to top, and then form a knot 9011 at the upper end of the first fixing ring 9231; in the unused state, the hauling cable 901 is retracted by the winch 90, and the telescopic measuring tube is in a contracted state under the pulling of the hauling cable 901, and at this time, the first section measuring tube 92, the middle measuring tube 93 and the last section measuring tube 94 are sleeved together layer by layer from inside to outside.

The inner diameter of the fourth cylindrical cavity 941 is determined according to the beam angle, the measuring range, the upper limit and the lower limit of the monitored liquid level, and the market plate staff gauge of the second ultrasonic measuring apparatus 920, as shown in fig. 29, and the radial dimension of the fourth cylindrical cavity 141 is reduced on the premise of meeting the measuring range; and the measured diameter D of the second ultrasonic meter 920 can be calculated by the following formula:

wherein l represents the measuring range of the ultrasonic measuring instrument and is 0.450-15.000 m;

alpha represents the sound beam angle of the second ultrasonic measuring instrument 920;

as can be seen from the design conditions of the sewage tank in the embodiment, the upper limit and the lower limit of the detected liquid level are +178.00m to +184.00m; the liquid level fluctuation value between the two liquid level fluctuation values is 184.00m-178.00 m=6m; the range of the second ultrasonic measuring instrument 920 is set to 10.00m <15.00m (the set value satisfies the range of 0.450m to 15.000 m) in consideration of the size of the immersed portion of the filter cover 91 and the increase in the long-term sewage treatment capacity;

d=2x10x0.04366=0.873m

Considering the surge effect of the leachate entering the sewage pool, the telescopic measuring cylinder is caused to swing to cause the sound beam wave to generate false reflection in the inner space of the telescopic measuring cylinder, and the diameter of the fourth cylindrical cavity 941 is set to be d=1m, namely, the diameter of the fourth cylindrical cavity 941 is larger than or equal to 1 m.

When the liquid level of the sewage pool is required to be measured, the winch 90 is started to pay out the traction rope 901, the telescopic measuring cylinder is gradually stretched along with the extension of the traction rope 901, and the upper ends of the middle measuring cylinder 93 and the end measuring cylinder 94 are limited at the lower ends of the upper section measuring cylinders respectively.

When the filtering cover 91 stretches into the leachate, sewage enters the telescopic measuring cylinder through the filtering holes 915, and because the side annular wall of the first section measuring cylinder 92 is provided with a plurality of air holes 921, the telescopic measuring cylinder can form an atmosphere communicating pipe under the effect of balanced air resistance. Because the cone 912 is provided with a plurality of filtering holes 915, when the leachate enters the telescopic measuring cylinder, the dirt floating cover layer is isolated outside the telescopic measuring cylinder by the cone 912, so that the dirt floating cover layer is effectively shielded. The liquid level of the leachate can fluctuate along with the insertion of the telescopic measuring cylinder, but the fluctuation of the liquid level can be restrained by the interaction between the internal friction force of the sewage and the balance air resistance, so that the liquid level in the telescopic measuring cylinder can change along with the lifting change of the liquid level of the leachate pool, the relative stability of the liquid level can be maintained, and the follow-up liquid level measurement of the liquid level by workers is facilitated.

As shown in fig. 28, when the lower portion of the filtering cover 91 contacts the bottom of the leachate tank, measurement of the liquid level of the leachate tank can be started. Starting a second ultrasonic measuring instrument 920, wherein an acoustic beam incident wave of the second ultrasonic measuring instrument 920 is emitted into the inner space of the telescopic measuring tube from the through hole, the acoustic beam incident wave is reflected upwards to the second ultrasonic measuring instrument 920 after contacting the liquid level downwards, the second ultrasonic measuring instrument 920 can obtain the time t of the emission and reflection process and send the data to the control device, the propagation speed of ultrasonic waves in gas is a known parameter c, and then the distance between the second ultrasonic measuring instrument 920 and the liquid level is x, x=c t/2; before the leachate is introduced into the leachate tank, the distance H between the second ultrasonic measuring instrument 920 and the bottom of the leachate tank can be measured and obtained by the same method, and the liquid level h=h-x=h-c×t/2 of the leachate tank can be obtained, and the control device can control the sewage pump connected with the control device to adjust the liquid level of the leachate in the leachate tank after obtaining the liquid level so as not to overflow from the leachate tank.

As shown in fig. 26-27, after the device is used for a period of time, the cone 912 may bind with a lot of dirt, which may clog the filter holes 915, affecting the normal use of the device, thus requiring timely cleaning. When cleaning is needed, starting the power equipment to wind up the traction rope 901, enabling the telescopic measuring cylinder to be contracted to an initial state, enabling the whole telescopic measuring cylinder not to be located in a leachate pool any more, rotating a nut 9143 to unscrew the telescopic measuring cylinder from the end part of the fixed screw 9142, holding a limiting block 9141 to withdraw the fixed screw 9142 from the jack, releasing the fixed state of the conical cylinder 912 by a fixing piece 914, enabling the conical cylinder 912 to be rotated and opened by taking a hinge point of the hinge seat 913 as a circle center, and cleaning dirt on the surface of the conical cylinder 912 by a high-pressure water gun; after cleaning, the cone 912 is repositioned according to the procedure described above.

In addition, the first ultrasonic measuring instrument 102, the power motor, the driving motor 232, the first driving motor 41 and the second driving motor 42 are all connected with the PLC controller to perform automatic and intelligent operation management, so that the working strength is greatly reduced.
