DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0026] When the sewage pressure in the pipe acts on the pressure sensitive element 406, the resistance or capacitance value of the pressure sensitive element 406 will change, which is converted into a standard electrical signal by the built-in circuit and transmitted to the pressure display 404. The measurement range of the pressure sensitive element 406 can be selected according to actual needs. In the sewage backwashing system, according to the expected value of the pressure at different positions, select the appropriate range of pressure sensitive element 406 to ensure the accuracy of the measurement. Pressure changes can reflect many problems, for example, during backwashing, if the pressure in the water inlet pipe 1 suddenly rises, it may be that the backwashing water cannot pass through the sand filter layer smoothly, which may be due to the sand filter layer being overcompacted or the nozzle being blocked, causing the backwashing water to be unable to be normally discharged.
[0027] Specifically, during the backwashing of the sewage pipe, first, the clean water is pumped into the water inlet pipe 1 through the water inlet pipe 8 by the water pump 9. During this process, the water passes through the pressure transmission channel 405 inside the metal shell 401, and the pressure sensitive element 406 receives the internal pressure. The value displayed on the pressure display 404 shows that if the pressure suddenly rises, it may be that the backwashing water cannot pass through the sand filter layer in the sand filter tank filter 7 smoothly, which may be due to the sand filter layer being overcompacted and blocked, causing the backwashing water to be unable to be normally discharged or the water pump 9 being faulty, that is, the input end of the backwashing water and the sand filter layer can be detected. Example two
[0028] Please refer to the attached Figure 1 - attached Figure 4 and attached Figure 6 , and on the basis of example one, further obtained, the flow detection device 5 includes an open tubular body 501, both ends of the open tubular body 501 are fixedly installed with a fixed plate 505, a plurality of thread holes are evenly distributed on the surface of the two fixed plates 505, and the thread holes are threadedly connected with locking bolts 506, the bottom of the circumferential surface of the open tubular body 501 is fixedly installed with a mounting shell 503, an ultrasonic transducer 504 is arranged between the inner surface of the mounting shell 503 and the open tubular body 501, the open tubular body 501 is sleeved on the circumferential surface of the drain pipe 3, the circumferential surface of the open tubular body 501 is fixedly installed with a flow display screen 507, the ultrasonic transducer 504 is signal connected with the flow display screen 507, and the inner wall of the open tubular body 501 is fixedly installed with an anti-skid pad 502.
[0029] Since the sewage is flowing, the propagation time of the ultrasonic waves in the ultrasonic transducer 504 in the downstream and upstream directions will be different, by measuring this time difference, combined with the diameter of the pipeline and other parameters, the flow rate of the sewage can be accurately calculated, this ultrasonic transducer 504 has high precision, can adapt to sewage pipelines with different diameters and flow ranges, detects the flow rate at the inlet and outlet of the filter device, if the difference between the inlet and outlet flow rates is too large, in addition to the possibility of sand filter layer blockage, there may also be foreign matter accumulation inside the pipeline, etc., by tightening the locking bolt 506, the open tubular body 501 can be firmly installed on the outer surface of the drain pipe 3.
[0030] Specifically, first, the open tubular body 501 is fixed on the circumferential surface of the drain pipe 3 through the locking bolt 506, the backwash water enters the drain pipe 3 after passing through the sand filter layer in the sand filter 7, at this time, the ultrasonic waves in the ultrasonic transducer 504 measure the flowing sewage, and the measured value is displayed on the flow display screen 507, by observing the change of the value, it is ensured that whether the amount of flowing sewage in the drain pipe 3 is reduced, if the difference is too large, it can be detected that the sand filter layer is blocked or there is a fault of foreign matter accumulation inside the pipeline.

By observing if there is an abnormality, it can be detected that the sand filter layer in the sand filter tank filter 7 may not be fully washed clean.
