[0045] Preferably, the hose 2 is also provided with a hose valve Preferably, the hard tube 201 is a steel tube.

[0048] Preferably, a groove is provided on the top of the water reservoir 6, and the groove is convenient for placing the fixed pulley 8.

[0049] Preferably, a small hole is left on the upper side wall of the insulating hollow tube 11, and the small hole is used to connect the second power line 702.

[0050] The present invention also provides a self-cleaning inspection well that can purify pollutants, and mainly comprises the following steps: a. When in use, the staff closes the main switch 1301 and connects the first power line 701 at the positive pole, opens the hose valve on the hose 2, and the runoff rainwater with suspended matter, garbage, etc. enters the multi-layer filter through the water inlet pipe.

[0051] b. After being purified by multi-layer filters, suspended solids, garbage, and sand and gravel in the runoff sewage are intercepted and precipitated in the multi-layer filter system, and clean rainwater flows through the outlet pipe to the downstream inspection well or river.

[0052] c. When rainfall brings mud and causes the bottom of the filter to be blocked, the water level inside the filter 3 rises, and most of the granular gravel and silt are intercepted in the first filter 3 and deposited in the impurity tank 302. However, the loose and fine muddy water in the water will still be discharged from the first filter 3 and slowly deposited at the bottom of the inspection well 1 after being dispersed by water. The mud deposition height will eventually slowly block the inlet of the discharge pipe 4. After the blockage, the outlet flow of the discharge pipe 4 slowly decreases, and the water level in the inspection well 1 continues to rise until it is filled with the reservoir 6. The water level of the reservoir 6 slowly rises, driving the float 1002 to rise and float up the frame 1001 through buoyancy. The top rod 1005 of the frame 1001 pushes up the first magnet 10, and the spring 1004 is stretched accordingly until the first magnet 1 0 and the second magnet 1201 are very close, the two magnets are attracted to each other by magnetic force, and at the same time, the magnets are closed and conductive, and the water pump 7 pumps water, and the water pump 7 flushes the inlet of the discharge pipe 4 through the outlet of the flushing pipe 1 903, and the water pump 7 is aimed at the inlet of the flushing filter tube 5 through the flushing pipe 2 904. The water pump 7 flushes the mesh wall on the side of the first filter screen 3 through the rotary valve 901 equipped with multiple nozzles 902, and the sludge adsorbed on the first filter screen 3 is flushed away. At the same time, after the discharge pipe 4 of the inspection well 1 is unblocked, the water in the inspection well 1 and the water reservoir 6 is discharged through the discharge pipe 4, and the water level will eventually drop. The pendant 1003 gradually leaks out of the water and pulls the first magnet 10 and the second magnet 1201 apart again by gravity. The pendant 1003 falls on the ladder platform 601, and the water pump 7 automatically cuts off the power.

[0053] Finally, the first magnet 10 is re-hung on the bottom inner wall of the magnetic switch 12; the hole at the bottom of the magnetic switch 12 is fixedly connected to the outer wall at the top of the insulating hollow tube 11, and the spring 1004 retracts to its normal state. The spring 1004 is made of conductive metal and can buffer the tensile force caused by the up and down floating of the power cord 701.

[0054] When the float 1002 floats up, the height of the pendant 1003 is at least 0.5m lower than the top of the frame 1001 to prevent the water pump 7 from tripping repeatedly and damaging the water pump 7; the water reservoir 6 is in an open state; when the gravel in the first filter screen 3 is full, close the hose valve on the hose 2, and take the hose 2 out directly from the hard pipe 201. The first filter screen 3 and the impurity tank 302 connected together can be transferred out by the existing crane through the hook fixed connection ring 304. The staff will patrol and inspect regularly every 3 to 4 months, so as to transport the weeds and gravel in the first filter screen 3 out and then hang the first filter screen 3 back on the bracket 303; the bottom of the first filter screen 3 and the bottom of the impurity tank 302 are fixed by multiple bolts. This detachable structure is convenient for pouring out the gravel in the impurity tank 302, etc. When there is too much soft fine mud and water mixture outside the bracket 303, the patrolling staff will turn on the power of the high viscosity pump 101, and the bottom mud and water mixture, suspended mud cleaning, etc. can be concentratedly pumped to the sludge collection tank through the high viscosity pump 101. The discharge pipe 4 is installed above the high viscosity pump 101 of the sludge discharge device.

[0055] The hose 2 is put back into the hard tube 201, and then the hose valve on the hose 2 is opened.

[0056] The height of the step 601 below the pendant 1003 is greater than the height of the water pump 7 to prevent the water pump 7 from being damaged due to idling; the water reservoir 6 is provided with a step 601, and the height of the step 601 is greater than the height of the water pump 7. The height of the discharge pipe 4 is less than the installation height of the filter pipe 5, ensuring that the water flow rate of the discharge pipe 4 is greater than the filter pipe 5; the installation height of the filter pipe 5 is less than the horizontal height of the hard pipe 201. It is ensured that no water will overflow directly from the inlet of the hard pipe 201.

[0057] The water pump 7 cleans the filter screen of the discharge pipe 4, the first filter screen 3, and the second filter screen 501. When the sewage contains a lot of sludge deposits after cleaning, it can also be discharged to a nearby sludge collection tank through the high viscosity pump 101.

[0058] Preferably, gravity of the first magnet 10 + gravity of the spring 1004 + gravity of the frame 1001 + gravity of the buoy 1002 + gravity of the pendant 1003 > attraction of the magnet 1201 on the first magnet 10 > gravity of the first magnet 10 + gravity of the spring 1004 + gravity of the frame 1001 + gravity of the buoy 1002 + gravity of the pendant 1003 - buoyancy of the pendant 1003.

[0059] Preferably, the float 1002 is a hollow rubber ball, which is not prone to rust or breakage.

[0060] Preferably, the pendant 1003 is a hollow aluminum ball, which is not easy to rust and can mitigate the impact when entering water compared to a solid aluminum ball.

[0061] Preferably, the magnetic switch 12 is fixedly installed at a high place and suspended in the air by a fixing rod. The height of the magnetic switch 12 can be adjusted as needed. The water reservoir 6 is openly arranged, and its water storage height is not limited by the installation height of the filter tube 5.

[0062] A method for using an inspection well device with integrated pollutant purification and self-cleaning functions, comprising the following steps: S1, placing the pendant 1003 and the floating ball 1002 on the step platform 601; S2, turn on the electronic control device 905 again, close the main switch 1301, and open the valve of the hose 2; Set the total gravity of "first magnet 10+spring 1004+frame 1001+all floating balls 1002+pendant 1003" in the inspection well device>the attraction of magnet 1201 to the first magnet 10>the total gravity of "first magnet 10+spring 1004+frame 1001+all floating balls 1002+pendant 1003"-the buoyancy of "pendant 1003"; The height of the pendant 1003 in the inspection well device is set at least 0.5m lower than the bottom connection of the frame 1001.

[0063] The pendant 1003 is a hollow aluminum ball, and the buoyancy of the hollow aluminum ball in water is between 1 / 2 and 3 / 4 of the weight of the hollow aluminum ball. The gravity of the power cord 701 is negligible.

[0064] Preferably, the sum of the thickness of the pendant 1003 and the length of the rope is ≤ the maximum vertical distance from the first magnet 10 to the magnet 1201 ≤ the length of the top rod 1005 of the frame 1001 - the length of the insulating hollow tube 11.

[0065] One or more high-viscosity pumps 101 may be provided, which are sequentially dispersed at different positions at the bottom of the inspection well 1 , so that the fine silt sediment deposited at the bottom of the inspection well 1 can be discharged.
