DETAILED DESCRIPTION

[0047] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0051] The transposition cleaning mechanism is arranged inside the housing 1 and connected to the filter mechanism for cleaning different positions of the filter mechanism. The transposition cleaning mechanism includes an outer tube 6 arranged inside the filter cartridge 4, an inner tube 8 fixedly connected to the inner part of the outer tube 6, and a first driving assembly for driving the outer tube 6 to rotate and lift.

A shell 10 is also fixedly connected to the top of the sealing plate 5, and the shell 10 is located on the inner side of the scraper ring 9. A plurality of through grooves are provided on the outer side wall of the shell 10, and one of the sealing plates 5 and its top is fixedly connected to the inner wall of the scraper ring 9. The shell 10 of the outer tube 6 is rotatably sleeved on the outside of the outer tube 6, and another sealing plate 5 and the shell 10 on the top thereof are rotatably sleeved on the outside of the inner tube 8; one side of the outer tube 6 and the inner tube 8 are connected with a slag guide pipe 11, and the slag guide pipe 11 is located on the inner side of the shell 10, and the tops of the outer tube 6 and the inner tube 8 are rotatably connected with a connecting tube 12, and the outer walls of the two connecting tubes 12 are connected with a dust suction pipe 13, and the dust suction pipe 13 is a Y-shaped structure. Two first solenoid valves 14 are installed on the dust suction pipe 13, and a limit block can be installed on the outside of the dust suction pipe 13, and two limit rods are arranged on the top of the box body 1, and the limit block The first drive assembly includes a bracket 15 mounted on the top of the housing 1, a first drive shaft 16 and a second drive shaft 17 rotatably connected to the inner wall of the top of the bracket 15, and a first motor 18 mounted on the top of the bracket 15; a first reciprocating screw 19 is fixedly sleeved on the outside of the first drive shaft 16, and a first lifting block 2 is screwed on the outside of the first reciprocating screw 19. 0, a first one-way gear 21 is also installed on the outside of the first drive shaft 16; a first sleeve 22 is slidably sleeved on the outside of the second drive shaft 17, and a first gear 23 is fixedly sleeved on the outside of the first sleeve 22 and the outer tube 6, and the two first gears 23 are meshed with each other, and the first lifting block 20 is also rotatably sleeved on the outside of the outer tube 6 and the first sleeve 22, and a second one-way gear 24 is also installed on the outside of the second drive shaft 17; a second gear 25 is fixedly sleeved on the outside of the output shaft of the first motor 18, and the second gear 25 is respectively meshed with the first one-way gear 21 and the second one-way gear 24;

[0052] When rainwater enters the filter cartridge 4 through the water inlet pipe 2, the rainwater is located on the top of the upper sealing plate 5, and is filtered by the filter cartridge 4 in the area above the sealing plate 5. When the inner wall of the filter cartridge 4 in this area needs to be cleaned, the first motor 18 is controlled to drive the second gear 25 to rotate forward, and the meshing effect between the second gear 25 and the first one-way gear 21 drives the first drive shaft 16 to rotate. At this time, the second one-way gear 24 rotates accordingly, but the second drive shaft 17 does not rotate accordingly. When the first drive shaft 16 rotates, it drives the first reciprocating screw 19 to rotate synchronously, and then drives the first lifting block 20 to move from the bottom end of the first reciprocating screw 19 to its top end. In this process, the outer tube 6 and the inner tube 8 are driven to move upward synchronously, and then the two sealing plates 5 are driven to move upward synchronously, so that the water inlet pipe 2 is located between the two sealing plates 5. In this process, the scraper 9 on the top of the upper sealing plate 5 moves upward along the inner wall of the filter cartridge 4, cleaning the filter cartridge 4 previously in the filtration area. The inner wall is cleaned, and the cleaned particle impurities fall along the inclined surface of the scraper circle 9 to between the scraper circle 9 and the shell 10. At this time, rainwater is injected into the filter cartridge 4 through the water inlet pipe 2, and filtered through the filter cartridge 4 in the area above the lower sealing plate 5, while the upper sealing plate 5 is in an idle state at this time. The second gear 25 is driven to reverse by controlling the first motor 18, and the second drive shaft 17 is driven to rotate at a low speed through the meshing effect between the second gear 25 and the second one-way gear 24. At this time, the first one-way gear 21 also rotates therewith, but the first drive shaft 16 does not rotate therewith. When the second drive shaft 17 rotates, the outer tube 6 is driven to rotate through the meshing effect between the two first gears 23. When the outer tube 6 rotates, it drives the slag guide pipe 11 to rotate synchronously. At this time, the upper first solenoid valve 14 is in a closed state, and the lower first solenoid valve 14 is in an open state. Therefore, during the rotation of the slag guide pipe 11, the particle impurities between the upper shell 10 and the scraper circle 9 are sucked out by the suction force of the dust suction pipe 13;

[0053] When it is necessary to clean the filter cartridge 4 in the lower filter area, the first motor 18 is controlled to drive the second gear 25 to rotate forward, drive the first reciprocating screw 19 to continue to rotate, and then drive the first lifting block 20 to move down from the top end of the first reciprocating screw 19 to its bottom end, thereby driving the two sealing plates 5 to move down and reset synchronously, and the rainwater is filtered through the filter cartridge 4 in the upper area again, and the lower sealing plate 5 is in an idle state, and then the first motor 18 is controlled to drive the second gear 25 to rotate in the reverse direction, drive the outer tube 6 and the inner tube 8 to rotate, and the inner tube 8 drives the slag guide pipe 11 to rotate synchronously when rotating. At this time, the first solenoid valve 14 at the bottom is in a closed state, and the first solenoid valve 14 at the top is in an open state, so that during the rotation of the slag guide pipe 11, the particulate impurities between the lower shell 10 and the scraper 9 are sucked out by the suction force of the dust suction pipe 13;

[0054] When the first lifting block 20 is lifted or lowered, the first gear 23 outside the first lifting block 20 is lifted or lowered synchronously by the outer tube 6 , and the first sliding sleeve 22 is used to drive the first gear 23 outside the first lifting block 20 to be lifted or lowered synchronously, so that the two first gears 23 are always kept in meshing state.

A plurality of first slide grooves 40 are also provided inside the connecting block 37, and a lifting rod 41 is slidably connected inside the first slide groove 40, and a first lifting rod 41 is fixedly connected to the top of the lifting rod 41. A spring 42, the top of the first spring 42 is fixedly connected to the inner wall of the top of the first slide 40, and the bottom of the lifting rod 41 is fixedly connected to the top of the control board 39; the outer part of the lifting shaft 28 is fixedly sleeved with a linkage frame 43, and the linkage frame 43 is fixedly connected to the inner wall of the liquid guide groove 38; a plurality of second slide grooves 44 are also provided inside the connecting block 37, and a stirring plate 45 is slidably connected inside the second slide groove 44, and the bottom of the stirring plate 45 slides and extends to the outside of the connecting block 37, and a second spring 46 is fixedly connected to the top of the stirring plate 45, and the top of the second spring 46 is fixedly connected to the inner wall of the top of the second slide groove 44, and the second driving assembly includes a second motor 47 installed at the bottom of the partition 26 and a second motor 47 connected to the bottom of the partition 26. The third driving shaft 48 of the second motor 47 is provided with a second sliding sleeve 49 on the outside of the output shaft, and a third gear 50 is fixedly sleeved on the outside of the second sliding sleeve 49 and the output shaft of the second motor 47; the third driving shaft 48 is fixedly sleeved with a second reciprocating screw 51 on the outside, and a second lifting block 52 is screwed on the outside of the second reciprocating screw 51, and the second lifting block 52 is rotatably sleeved on the outside of the second sliding sleeve 49 and the lifting shaft 28; the third driving shaft 48 is also provided with a third one-way gear 53 on the outside, and the third one-way gear 53 is meshed with one of the third gears 50; the lifting shaft 28 is provided with a fourth one-way gear 54 on the outside, and the fourth one-way gear 54 is meshed with another third gear 50;

[0056] When the outer tube 6 and the inner tube 8 rotate at a low speed, the telescopic shaft 33 is driven to rotate synchronously, and then the mixing barrel 27 is driven to rotate synchronously. When the feed trough 29 moves to the incomplete area of ​​the incomplete annular sealing block 30, the third gear 50 is driven to rotate forward by controlling the second motor 47. The third gear 50 is meshed with the third one-way gear 53 to drive the third drive shaft 48 to rotate. At this time, the fourth one-way gear 54 also rotates, but the lifting shaft 28 does not rotate. When the third drive shaft 48 rotates, the second reciprocating screw 51 rotates synchronously, thereby driving the second lifting block 52 to move from the top end of the second reciprocating screw 51 to its bottom end. In this process, The lifting shaft 28 is driven to move downward synchronously, thereby driving the connecting block 37 and the sealing ring 36 to move downward synchronously through the linkage frame 43, discharging the mixed liquid at the bottom of the connecting block 37, and pumping the filtered rainwater inside the box body 1 into the mixing cylinder 27 through the feeding trough 29. After the mixing cylinder 27 is full, the feeding trough 29 rotates to the bottom of the incomplete annular sealing block 30 and is sealed by the incomplete annular sealing block 30. The feeding trough 29 is connected with the injection pipe 34, and the third solenoid valve 35 is opened to inject the set nutrient into the mixing cylinder 27. Then the third solenoid valve 35 is closed, and then the second motor 47 is controlled to drive the third gear 50 to rotate forward, and the second reciprocating screw The rod 51 rotates synchronously therewith, thereby driving the second lifting block 52 to move from the bottom end of the second reciprocating screw 51 to its top end, thereby driving the connecting block 37 and the sealing ring 36 to move upward synchronously. In this process, since the feed trough 29 is sealed, the water pressure at the top of the connecting block 37 will push the control plate 39 open, and the lifting rod 41 moves downward accordingly, and the first spring 42 is stretched, thereby opening the liquid guide groove 38, and the rainwater and nutrient agent at the top of the connecting block 37 flow to the bottom of the connecting block 37 through the liquid guide groove 38. Then the second motor 47 is controlled to drive the third gear 50 to reverse, and the third gear 50 is meshed with the fourth one-way gear 54 to drive the lifting rod 41 to move upward synchronously. The lowering shaft 28 rotates, and the third one-way gear 53 also rotates accordingly, but the third driving shaft 48 does not rotate accordingly. When the lifting shaft 28 rotates, the connecting block 37 is driven to rotate synchronously through the linkage frame 43, thereby driving each stirring plate 45 to rotate synchronously, stirring the rainwater and nutrient agent inside the mixing barrel 27, so that the rainwater and nutrient agent are mixed evenly. When the feed trough 29 moves to the defective area of ​​the defective annular sealing block 30, the connecting block 37 and the sealing ring 36 are driven to move downward to discharge the evenly mixed rainwater and nutrient agent, and the cycle is used to achieve quantitative mixing of the filtered rainwater and nutrient agent, and the discharged mixed liquid is directly used for irrigation of plants inside the garden;

[0057] When the connection block 37 moves downward and the stirring plate 45 abuts against the inner wall of the bottom of the mixing barrel 27, as the connection block 37 continues to move downward, the stirring plate 45 automatically shrinks into the second chute 44, and the second spring 46 is compressed accordingly. When the connection block 37 moves upward, the rebound force of the second spring 46 drives the stirring plate 45 to automatically extend downward to facilitate subsequent stirring.

[0058] In addition, when the second lifting block 52 is lifted or lowered, the fourth one-way gear 54 outside the lifting shaft 28 is driven to be lifted or lowered synchronously, and the third gear 50 outside the second sliding sleeve 49 is driven to be lifted or lowered synchronously, so that the third gear 50 and the fourth one-way gear 54 are always kept in meshing state.
