When the filtering holes of the annular compartment 101 are not blocked or are blocked, water rarely enters the volute 103 and is enough, the water pressure in the volute 103 is higher than 3MPa (under the normal condition, the lift of the submersible pump body is 45 meters, and the water pressure in the volute is about 4.5 MPa), the internal contact of the pressure switch P is in an open circuit state at the moment, and because the pressure switch P is connected in series between the pin 3 at the positive power output end of the switching power supply A and the positive power input end VCC of the singlechip module A1, the singlechip module A1 is in a power-off and non-working state at the moment. In use, when the submersible pump body M works and water continuously enters the volute 103 through the annular partition 101, various impurity pollutants in the water can simultaneously contact the outer side end of the annular partition 101, when the outer diameter of the impurity pollutants is large enough and cannot be dispersed by water flow (such as harder sludge, leaves, plastic films and the like in the water), the impurity pollutants can block some of filter holes distributed on the annular partition 101 of the submersible pump body, so that the water quantity entering the volute 103 of the submersible pump body can be reduced, the water pressure in the volute 103 can be reduced, when the water pressure in the volute 103 is lower than 3MPa, the internal contact of the pressure switch P is in a closed state at the moment, and because the pressure switch P is connected between the pin 3 of the positive power output end of the switching power supply A and the positive power input end VCC of the singlechip module A1 in series, the singlechip module A1 is in an electric working state at the moment. After the single chip module A1 is powered on to work, under the action of an internal circuit of the single chip module A1, two power output ends 1 and 2, and 3 and 4 can output 10 seconds of power at intervals of 10 seconds and enter two relays J2 and J1 positive and negative pole power input ends, so that the two relays J2 and J1 can be powered on and attracted for 10 seconds alternately at intervals of 10 seconds respectively, and the positive and negative pole control power input ends (respectively communicated with the

pins

3 and 4 of the switching power supply A) and the two normally open contact ends of the two relays J2 and J1 are respectively communicated with each other at intervals of 10 seconds for 10 seconds; because the two normally open contact ends of the relays J2 and J1 and the positive and negative poles of the two sets of motor reducing mechanisms MN are respectively connected through the leads, the two sets of motor reducing mechanisms MN can circularly work under … … in a mode that the positive and negative poles of the power input ends are firstly electrified for 10 seconds, then the negative and positive poles of the power input ends are electrified for 10 seconds, and the positive and negative poles of the power input ends are electrified for 10 seconds again; thus, under the action of the internal motor and the gear reduction mechanism of the two sets of motor reduction mechanisms MN, the power output shafts of the two sets of motor reduction mechanisms MN circularly rotate downwards … … in a working mode of firstly rotating anticlockwise for 10 seconds, then rotating clockwise for 10 seconds and then rotating anticlockwise for 10 seconds until the power output ends of the singlechip module A1 do not output power (after the positive and negative pole power supply input ends of the two sets of motor reduction mechanisms MN are powered on, the internal motor rotating shafts rotate clockwise, under the action of the internal multi-stage gear reduction mechanism, the power output shafts rotate anticlockwise, and under the action of the internal multi-stage gear reduction mechanism, the negative and positive pole power supply input ends of the two sets of motor reduction mechanisms MN are powered on, the internal motor rotating shafts rotate clockwise). When the power output shafts of the two sets of motor reducing mechanisms MN rotate anticlockwise, the external thread lead screws 63 at the lower ends of the two sets of motor reducing mechanisms MN (the rotating speeds are consistent and the specifications and models are completely consistent) can respectively act on the internal threads of the thread seats 71 at the left end and the right end of the foreign matter cleaning equipment at the same time, so that the foreign matter cleaning equipment 7 can descend along the annular compartment 101 for about 10 seconds, and when the foreign matter cleaning equipment 7 descends to be close to the upper end of the lower part of the water pump body shell 102, at the moment, the power output end 1 and the pin 2 of the first path of power supply of the single chip microcomputer module A1 can not output power supply any more, the relay J2 is not used for attracting the input ends of the two positive and negative pole control power supplies and the two normally open contact ends; after the singlechip module A1 outputs power supply by the second power output end 3 and the second power output end 4, the relay J1 is electrified to attract the two positive and negative pole control power input ends (respectively communicated with the

pins

3 and 4 of the switch power supply A) and the two normally open contact ends, the power output shafts of the two sets of motor reducing mechanisms MN rotate clockwise, the external thread lead screws 63 at the lower ends of the two sets of motor reducing mechanisms MN can respectively and simultaneously act on the internal threads of the screw bases 71 at the left and right ends of the foreign matter cleaning equipment, so the foreign matter cleaning equipment 7 can move upwards along the annular compartment 101 for about 10 seconds, when the foreign matter cleaning equipment 7 moves upwards to approach the lower end of the upper part of the water pump body shell 102, at the moment, the singlechip module A1 outputs power supply by the second power output end 3 and the second power output end 4, the relay J1 loses electricity and does not attract the two positive and negative pole, the two sets of motor reducing mechanisms MN do not work any more, so the foreign matter cleaning equipment 7 does not go upwards … … any more; through the above, under the action of the internal circuit of the single chip microcomputer module a1, the foreign matter cleaning device 7 will continuously reciprocate upward and downward outside the annular compartment 101. Because, the medial extremity of the ring cover of the foreign matter cleaning equipment 7 and the outside end of the annular compartment 101 are very close in separation distance (1 mm), so that the foreign matter cleaning equipment 7 which goes up and down is inboard, and the foreign matter including hard sludge which adheres and blocks the filter hole outside the compartment 101 is cleaned, thereby effectively ensuring that the water can smoothly enter the volute 103, the submersible pump body M can normally work under high power, and the probability of damage of the submersible pump body M is reduced (the submersible pump body idles, and the mechanical sealing part is easily burnt out due to no water cooling). In practical situations, when foreign matters are scraped off at the outer end of the filter hole of the annular compartment 101 and the water amount entering the volute of the submersible pump body M is enough, the water pressure in the volute 103 is increased again, and the water pressure in the volute 103 is higher than 3MPa again, the internal contact of the pressure switch P is in an open circuit state again, the single chip microcomputer module a1 is in a power-off non-working state, so that the two sets of motor speed reducing mechanisms MN can not drive the foreign matter cleaning equipment 7 to move upwards or downwards any more, and preparation is made for next use; when the filtering hole of the annular compartment 101 is blocked again next time and the water pressure in the volute 103 is lower than 3MPa again, the singlechip module A1 controls the motor speed reducing mechanism MN to work again, and the foreign matter cleaning equipment 7 moves upwards or downwards again to clean the foreign matters outside the annular compartment 101.

As shown in fig. 1, 2 and 3, in the present invention, if the foreign object cleaning device 7 goes upward or downward to the top dead center or the bottom dead center and approaches the lower end of the upper part and the upper end of the lower part of the water pump body housing 102 located at the annular compartment, the upper part or the lower part of the foreign object cleaning device 7 will contact the action buttons of the two micro switches S, S1 respectively, so that the internal contacts of the two micro switches S, S1 will be open-circuited respectively; because the two micro switches S1 and S are respectively connected in series between one normally open contact end of the positive relay J2 at the first power output end of the single chip microcomputer module and the positive power input ends of the two sets of motor reduction mechanisms MN through leads, and between one normally open contact end of the positive relay J2 at the second power output end of the single chip microcomputer module and the negative power input ends of the two sets of motor reduction mechanisms MN, after the foreign matter cleaning equipment 7 is in uplink contact with the keys of the micro switches S and the foreign matter cleaning equipment 7 is in downlink contact with the keys of the micro switches S1, the two sets of motor reduction mechanisms MN can lose power and do not work, the foreign matter cleaning equipment 7 does not continue to be in uplink or downlink, and the problem that the equipment cannot work normally due to too much uplink or downlink of the foreign matter cleaning equipment 7 is effectively prevented. Because, foreign matter cleaning equipment 7 goes upward the button that contacts micro-gap switch S, motor reduction mechanism MN loses the electricity after, when the power that two normally open contact ends of single chip module A1 first way power output end relay J2 were exported gets into motor reduction mechanism MN plus-minus two-pole power input end, micro-gap switch S1' S button is not withstood the internal contact and is in the closed state this moment, so can not get electric to motor reduction mechanism MN plus-minus two-pole power input end, follow-up foreign matter cleaning equipment 7 descends and causes the influence. Because foreign matter cleaning equipment 7 contacts the key of micro-gap switch S1 downwards, after the motor reducing mechanism MN loses electricity, when the power output by two normally open contact ends of the second power output end relay J1 of the single chip module A1 enters the power input end of the motor reducing mechanism MN with negative and positive poles, the button of the micro-gap switch S is not jacked by the internal contact at the moment and is in a closed state, so the power input end of the motor reducing mechanism MN with negative and positive poles can not be electrified, and the subsequent foreign matter cleaning equipment 7 goes upwards to cause influence. The utility model discloses can clear up the adhesion and the foreign matter that blocks up including harder mud in the filter hole outside of compartment 101 to effectively guaranteed that hydroenergy is unblocked to get into spiral case 103 in, immersible pump body M can normally work under high-power, and reduced the probability that immersible pump body M damaged. Relays J1, J2 are 12V dc relays having two power inputs, two control power inputs, two normally open contact ends, two normally closed contact ends.
