A well water filtering device comprises a sand filtering piece 00, a supporting leg 01, a first pipe 10, a third pipe 15, a second pipe 20, a small-diameter section 21, a slide way 22, a sand leaking hole 23, a baffle ring 30, a sleeve 40, a fixing hole 41, a sand containing cup 50, a gear ring 60, a second gear 70, a servo motor 80 and a PLC 90;

two ends of the second pipe 20 are fixedly connected with the adjacent ends of the first pipe 10 and the third pipe 15 respectively, one end of the second pipe 20 inclines downwards, the free end of the first pipe 10 is used for being communicated with a water pump, and the free end of the third pipe 15 is used for being communicated with a leakage pipe.

A plurality of legs 01 are fixed below the first pipe 10 and the third pipe 15, and the legs 01 are used for fixedly supporting the whole of the first pipe 10, the third pipe 15 and the second pipe 20.

Referring to fig. 2, the pipeline of the second pipe 20 has a small diameter section 21, the upper surface of the second pipe 20 is concave downward to form a slideway 22, and the lower end of the slideway 22 extends to the small diameter section 21, that is, the slideway 22 is communicated with the cavity outside the small diameter section 2.

Referring to fig. 1, two retaining rings 30 are fixedly inserted through the outer side of the second pipe 20, and the slide 22 passes through the inner holes of the retaining rings 30.

The sleeve 40 is rotatably sleeved outside the second pipe 20 in a penetrating manner, the inner wall of the sleeve 40 is tightly attached to the cylindrical outer side wall of the second pipe 20, two ends of the sleeve 40 are in sealing contact with a baffle ring 30, and two opposite fixing holes 41 are formed in the wall of the sleeve 40; further, the retainer ring 30 is made of rubber.

Each fixing hole 41 is embedded with a cup mouth for fixing a sand containing cup 50.

A sand leakage hole 23 is formed in the lower edge of the outer wall of the second pipe 20; and when one sand containing cup 50 is positioned at the lower side of the second pipe 20, the sand containing cup 50 is communicated with the sand leaking hole 23, namely, the sand containing cup 50 is communicated with the inner cavity of the second pipe 20 through the sand leaking hole 23.

The edge of the sand filtering piece 00 is completely fixedly and hermetically connected with the inner wall of the second pipe 20, and the sand filtering piece 00 is positioned at a position lower than the sand leaking hole 23; the sand filtering piece 00 is used for intercepting sand grains in water, and further, the sand filtering piece 00 can be gauze.

The inner diameter of the gear ring 60 is sleeved and fixed on the outer wall of the sleeve 40, and the second gear 70 is meshed with a gear surface on the outer wall of the gear ring 60; the free end of the rotating shaft of the servo motor 80 is fixed with one end face of the second gear 70.

The PLC90 is fixed on the support leg 01, and the PLC90 is electrically connected with the servo motor 80; the PLC90 controls the servo motor 80 to rotate and the gear ring 60 to rotate 180 degrees after every predetermined time interval (the predetermined time interval is reasonable within one hour in half an hour).

Using steps and principles:

1) the free end of a first pipe 10 is communicated with a water outlet of a water pump, and the free end of a third pipe 15 is communicated with a leakage pipe;

2) connecting the PLC90 with a power supply;

the well water flows from the upper end of the second pipe 20 to the lower end of the second pipe 20, and when the well water passes through the sand filtering member 00, the silt in the well water is intercepted by the sand filtering member 00, and referring to fig. 3, the silt intercepted by the sand filtering member 00 falls into the sand containing cup 50 through the sand leaking hole 23. (because the inner wall of the sleeve 40 is tightly attached to the outer cylindrical wall of the second pipe 20, and both ends of the sleeve 40 are in sealing contact with the baffle ring 30, so that water cannot flow out from the inner wall of the sleeve 40 and the outer wall of the second pipe 20.) after a preset time interval, the sand containing cup 50 at the lower side falls into some sediment in the well water, the PLC90 controls the servo motor 80 to rotate, the gear ring 60 drives the sleeve 40 to rotate 180 degrees, then the two sand containing cups 50 reverse positions, the sand containing cup 50 with the sediment settled rotates to the upper side of the slideway 22, the cup mouth of the sand containing cup is downward at the moment, the sediment in the sand containing cup 50 falls into the slideway 22, and the sediment falls onto the ground through the outer wall of the small diameter section 21.

In conclusion, the silt intercepted by the sand filter 00 can be transported to the water pipe without stopping the irrigation operation, so that the silt in the well water is intercepted before the well water enters the micro-jetting zone, and the silt is transported out of the second pipe 20.

Viscous sediment in the sand containing cup 50 cannot flow out into the slide way 22 completely, a thick layer of sediment can be remained on the inner wall of the sand containing cup 50, and the thick sediment reduces the next sand containing amount of the sand containing cup 50.

Further, the rim of the sand containing cup 50 is completely and fixedly connected with the edge of the elastic membrane 100; two ends of the communicating pipe 120 are respectively fixed on the outer walls of the two sand containing cups 50, and the communicating pipe 120 is communicated with the inner cavities of the two sand containing cups 50, that is, the two elastic membranes 100 form a sealed space by the communicating pipe 120 and the inner cavities of the two sand containing cups 50; the communication pipe 120 and the two sand containing cups 50 are filled with only water (without air) in the whole inner cavities, and the volume of the water is equal to that of one sand containing cup 50; that is, when water completely enters one sand-containing cup 50, the inner wall of the other sand-containing cup 50 is completely attached by the elastic membrane 100 at the cup mouth (see fig. 5). Two ends of the iron wire 110 are respectively fixed on the uppermost edges of the inner walls of the two baffle rings 30, and the iron wire 110 is further contacted with the inner wall of the sleeve 40;

the principle is as follows: (referring to fig. 4 and 5), when the sand-containing cup 50 (with the sand and sand in the inlet water inside) originally located at the lower side of the second pipe 20 rotates to the upper side of the second pipe 20, the sand-containing cup 50 originally located at the upper side of the second pipe 20 rotates to the lower side of the second pipe 20, and at this time, the elastic membrane 100 at the mouth of the sand-containing cup 50 located at the lower side of the second pipe 20 is expanded by the water pressure inside the second pipe 20 to be attached to the inner wall of the sand-containing cup 50 at the lower side; the water in the whole inner cavities of the communication pipe 120 and the two sand containing cups 50 all enters the inner cavity of the upper sand containing cup 50, and the water in the upper sand containing cup 50 presses down the elastic membrane 100 of the upper sand containing cup 50 and protrudes out of the opening of the sand containing cup 50; meanwhile, the elastic membrane 100 of the upper sand containing cup 50 rotates through the iron wire 110, and the iron wire 100 scrapes off all the silt on the elastic membrane 100 of the upper sand containing cup 50, so that the silt is not remained in the upper sand containing cup 50.

When silt falls on the slide way 22, a part of silt can be left in the slide way 22, and due to the fact that the silt can be rapidly dried in the slide way 22 in dry weather, the silt can block the slide way 22 over time, and finally even if the sand containing cup 50 rotates to the position above the slide way 22, the silt in the sand containing cup 50 cannot be discharged.

The plastic wiper also comprises a middle connection 135, a radial rod 130, a connecting rope 140, a plastic wiper blade 150 and a measuring tape 160;

one end of the radial rod 130 is in contact with the outer wall of the small diameter section 21, and the other end of the radial rod 130 is fixed on the outer wall of the sand containing cup 50 through an intermediate connection 135.

The plastic wiper blade 150 is positioned in the sliding groove of the slideway 22; one end of the connecting rope 140 is fixed on the plastic scraper 150, the other end of the connecting rope 140 is fixed on the lower end wall of the small-diameter section 21, and the plastic scraper 150 is fixedly connected with the free end of the measuring tape 160; further, the tape of the tape measure 160 is made of steel, and the spring inside the tape measure 160 is made of a material with a large elastic force.

The lower edge of the outer wall of the small diameter section 21 is provided with a concave pit 211 which is concave towards the axial direction.

The principle is as follows: when the upper radial rod 130 rotates, the radial rod 130 can not only clean the silt remained on the small diameter section 21, but also the radial rod 130 can drive the connecting rope 140 to rotate for a half circle around the outer wall of the radial rod 130, so that the plastic wiper 150 moves downwards along the slideway 22, the plastic wiper 150 wipes off the silt on the bottom surface of the slideway 22, and when the free end of the radial rod 130 moves to the pit 211, the connecting rope 140 breaks away from the gap between the free end of the radial rod 130 and the pit 211 and resets; since the winding spring of the tape measure 160 will pull the tape back, the tape will pull the plastic blade 150 back to its original position.

Further, the plastic wiper 150 is attached to the bottom surface of the slide 22.

Further, the stop ring 30 has an outer diameter larger than that of the sleeve 40.

Further, the plastic blade 150 contacts the bottom of the chute 22, and the plastic blade 150 is obliquely above the sleeve 40.

Further, the gear ratio of the gear ring 60 to the second gear 70 is 1:1, when the servo motor 80 controls the second gear 70 to rotate for half a turn, i.e. the gear ring 60 also rotates for half a turn with the sleeve 40; making control simple.

Preferably, the concave pits 211 are arc-shaped, and have a radius of 2-3 cm.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
