Description

Technical Field

[0001] The present invention relates to the technical field of rainwater treatment devices, and particularly to a non-powered rainwater purification mechanism. Background Art

[0002] Rainwater is a precious resource. By preliminarily treating the collected rainwater and then using it in fields such as urban greening, road spraying, and park green space irrigation, the pressure on the urban drainage system can be reduced and the reuse of water resources can be achieved. Therefore, a decentralized rainwater processor is needed to purify rainwater. The decentralized rainwater processor, also known as a non-powered integrated rainwater treatment device, is an efficient rainwater treatment equipment that does not consume external energy during operation and can complete the rainwater treatment process relying on the potential energy of rainwater itself, which is energy-saving and environmentally friendly.

[0003] When the existing non-powered rainwater purification device is in use, rainwater enters the interior of the device, and the water flow enters the guide plate along the tangential direction of the inner wall of the device, forming a swirl flow and a radial flow on the guide plate. In this way, the deposited particles and sediment fall to the bottom, and larger impurities are intercepted by the pollution interception basket. The rainwater that has undergone swirl separation continues to flow upward, and the rainwater is purified through the filter element, thereby outputting relatively ideal rainwater.

[0004] When the above non-powered rainwater purification device is installed in farmland, the soil in this area is relatively soft. Therefore, in the case of heavy rain, the soil is easily washed away by the rainwater and flows with the rainwater, causing a large amount of soil to enter the interior of the device. Subsequently, a large amount of soil accumulates inside the pollution interception basket, and the soil largely blocks the filter holes on the pollution interception basket. Moreover, due to the inconsistent sizes of the soil blocks, when some soil blocks coincide with the sizes of the filter holes and get stuck inside the filter holes, the situation of filter hole blockage will occur. When the filter holes are blocked or largely covered, it will cause sediment and water flow to be difficult to pass through the filter holes, resulting in sediment deposition on the filter element, reducing the effective filtration area in contact between the rainwater and the filter element, and thus causing the problem of reduced rainwater treatment efficiency of the filter element. Summary of the Invention

[0005] The purpose of the present invention is to propose a non-powered rainwater purification mechanism to solve the problem that a large amount of soil accumulates in the pollution interception basket, resulting in filter hole blockage, sediment deposition on the filter element, reduction of the effective filtration area in contact between the rainwater and the filter element, and thus causing the problem of reduced rainwater treatment efficiency of the filter element.

A positioning rod is fixedly connected to the upper surface of the diversion plate. A clamping groove is arranged on the surface of the positioning rod.

[0015] Further description of a power-free rainwater purification mechanism of the above technology: A first sealing member is fixedly connected to the inside of the fixing frame. One end of the rotating rod is rotatably connected to the inside of the first sealing member. A spring telescopic rod is arranged between the first sealing member and the cutting piece.

[0016] In summary, due to adopting a power-free rainwater purification mechanism of the above technology, the beneficial effects of the present invention are: 1. By providing a cutting blade and a push plate, in rainy weather, when rainwater washes the soil, a large amount of mud blocks enter the interior of the housing. A large number of mud blocks fall into the interior of the sewage interception basket. The mud blocks move towards the inner wall of the sewage interception basket along the inclined surface of the conical block. Subsequently, the turntable drives the push plate to rotate. The push plate pushes the mud blocks to rotate to the cutting blade, and through the acting force of the cutting blade and the push plate, large mud blocks can be broken, avoiding the accumulation of a large number of mud blocks in the sewage interception basket, blocking the filter tank, hindering the flow of rainwater and sediment to the bottom side of the housing to form precipitation, resulting in difficulty for sediment and water flow to pass through the filter holes, causing sediment to deposit on components such as the guide plate and filter element, reducing the effective filtration area of contact between rainwater and the filter element, and thus reducing the rainwater treatment efficiency of the filter element.

[0017] 2. By providing a limiting plate, a convex block and a rotating rod, when the turntable rotates, the turntable drives the convex block to rotate synchronously. Normally, the sliding rod is located below the limiting plate. When the convex block contacts the moving rod, the convex block pushes the moving rod upward, and the moving rod drives the fixed rod to move upward. The fixed rod cooperates with the spiral groove on the surface of the rotating rod, causing the rotating rod to rotate. The rotating rod drives the cutting blade to rotate, and the cutting blade rotates to break the soil block stuck between it and the filter tank, enabling the cutting blade to dredge the soil block between it and the filter tank, avoiding the soil block being stuck between the cutting blade and the filter tank, blocking the filter tank, and thus reducing the rainwater treatment efficiency.

[0018] 3. By providing a ratchet plate and a ratchet pawl, when the cutting blade resets, the cutting blade drives the first ratchet ring to rotate. The first ratchet ring is squeezed by the second ratchet ring, causing the cutting blade to vibrate when resetting, thereby shaking off the sticky soil blocks attached to the surface of the cutting blade, avoiding some soil from adhering to the cutting blade and coming into contact with sediment subsequently, causing the soil blocks to accumulate on the cutting blade, blocking the filter tank, and thus reducing the subsequent rainwater purification efficiency.

[0021] Next, the technical solution of a non-powered rainwater purification mechanism in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] As Figures 1-15 shown, the present invention provides a power-free rainwater purification mechanism, including a housing 1. The outer wall of the housing 1 is fixedly connected with a second water inlet pipe 14 and a drain pipe 15, and the height of the second water inlet pipe 14 is higher than that of the drain pipe 15. The second water inlet pipe 14 is tangent to the outer wall of the housing 1. The inner wall of the housing 1 is fixedly connected with a flow guide plate 2. The inner part of the housing 1 is fixedly connected with a support plate 3. A filter element 31 is fixedly connected to the support plate 3. A sewage interception basket 4 is snap-connected inside the flow guide plate 2. The sewage interception basket 4 is used for collecting large impurities carried by rainwater. A plurality of fixing frames 41 are fixedly connected to the inner wall of the sewage interception basket 4. A rotating rod 411 is rotatably connected to the inner wall of the fixing frame 41. A cutting blade 412 is slidably connected to the rotating rod 411. A groove is provided on the surface of the rotating rod 411, and the inside of the cutting blade 412 meshes with the groove. Therefore, during the rotation of the rotating rod 411, the cutting blade 412 is driven to rotate synchronously by the meshing of the groove and the cutting blade 412. A filtering groove 42 is formed between the cutting blade 412 and the fixing frame 41. Rainwater and sediment flow towards the inner bottom of the housing 1 through the filtering groove 42, and then the sediment gradually settles at the inner bottom of the housing 1. The lower surface of the sewage interception basket 4 is rotatably connected with a turntable 43. A conical block 434 is fixedly connected to the turntable 43. A push plate 433 is fixedly connected to the conical block 434. The outer wall of the housing 1 is fixedly connected with a sewage discharge pipe 16. The central part of the support plate 3 is fixedly connected with an exhaust pipe 32. The filter element 31 is arranged around the outer wall of the exhaust pipe 32; After the large mud block falls into the sewage interception basket 4, the mud block slides on the conical block 434 to the inner wall of the sewage interception basket 4, driving the turntable 43 to drive the conical block 434 to rotate. The conical block 434 drives the push plate 433 to rotate and push the mud block, so that the mud block rotates and contacts the cutting blade 412. The large mud block can be broken by the cooperation of the cutting blade 412 and the push plate 433.

[0023] Specifically, when the existing power-free rainwater purification device is in use, rainwater enters the device. The water flow enters the flow guide plate 2 along the tangential direction of the inner wall of the device, forming a swirling flow and a radial flow on the flow guide plate 2. In this way, the deposited particles and sediment fall to the bottom, and the larger impurities are intercepted by the sewage interception basket 4. The rainwater separated by the swirling flow continues to flow upward, and the rainwater is purified by the filter element 31, so as to output relatively ideal rainwater; When the above-mentioned non-powered rainwater purification device is installed in farmland or mountainous areas, in the case of heavy rain, the soil is easily washed away by the rainwater and flows along with the rainwater, causing a large amount of soil to enter the device. Subsequently, a large amount of soil accumulates inside the sewage interception basket 4 and blocks the filter holes inside the sewage interception basket 4, resulting in difficulty for sediment and water flow to pass through the filter holes, causing sediment to deposit on the filter element 31, reducing the effective filtration area in contact between the rainwater and the filter element 31, and thus causing the problem of reduced rainwater treatment efficiency of the filter element 31; To avoid the above problems, its working principle is as follows: In the case of heavy rain, the rainwater washes the soil, causing the soil to flow into the interior of the second water inlet pipe 14 along with the rainwater and enter the interior of the housing 1 through the second water inlet pipe 14. The water flow enters the guide plate 2 along the tangent of the inner wall of the housing 1. At this time, the water flow forms a swirling flow and a radial flow on the guide plate 2. The rainwater drives the sediment through the filter slots 42 on the sewage interception basket 4. The heavier impurities such as sediment particles and sediment in the rainwater are thrown towards the inner wall of the housing 1 under the action of centrifugal force and finally fall to the bottom to form a precipitate. The rainwater that has undergone preliminary swirling separation will continue to flow upward and flow towards the filter element 31. The filter element 31 is filled with various filter materials, which can further filter out the fine particles in the rainwater and adsorb and filter substances such as suspended solids, macromolecular organic matter, and colloids in the water. The rainwater treated by the filter element 31 can be discharged through the drain pipe 15, and at this time, the rainwater purification operation can be completed; A large number of soil blocks carried by the rainwater wash fall onto the conical block 434 inside the sewage interception basket 4. Due to the inclined surface of the conical block 434, a large number of convex blocks 432 slide towards the inner wall of the sewage interception basket 4. At this time, the turntable 43 below the sewage interception basket 4 is driven to rotate. The turntable 43 drives the push plate 433 and the conical block 434 to rotate. The push plate 433 pushes the soil blocks on the conical block 434 to rotate. The soil blocks come into contact with the cutting piece 412 and are pushed by the push plate 433. Since a large amount of rainwater quickly penetrates into the soil during heavy rain, the soil structure becomes loose and easy to break. Therefore, the soil blocks are limited by the cutting piece 412 at this time and are pushed by the push plate 433. Through the extrusion of the cutting piece 412 and the push plate 433, the soil blocks can be broken. The small pieces of soil generated after the soil blocks are broken float in the rainwater. At this time, the push plate 433 rotates to drive the rainwater to generate a swirling flow, and the centrifugal force generated causes the small pieces of soil to be thrown to the inner wall of the sewage interception basket 4, enabling the soil to pass through the filter slots 42 and form a precipitate at the bottom of the housing 1. When the use is completed, open the sewage discharge pipe 16 and connect a pump to pump out the precipitate at the bottom of the housing 1; This device can break up the mud blocks in the sewage interception basket 4 and settle them at the bottom of the outer shell 1 through the filter tank 42, avoiding the accumulation of a large amount of mud blocks in the sewage interception basket 4, blocking the filter tank 42, hindering the flow of rainwater and sediment to the bottom side of the outer shell 1 to form precipitation, making it difficult for the sediment and water flow to pass through the filter holes, causing the sediment to deposit on components such as the diversion plate 2 and the filter element 31, reducing the effective filtration area of contact between the rainwater and the filter element 31, and thus resulting in the problem of reduced rainwater treatment efficiency of the filter element 31.

[0024] As Figure 1 and Figure 2 shown, a support pipe 11 is fixedly connected to the outer wall of the outer shell 1. One end of the support pipe 11 is fixedly connected to a fixed shell 12. A first transmission rod 122 is rotatably connected inside the fixed shell 12. An impeller 121 is fixedly connected to the first transmission rod 122. A first water inlet pipe 13 is fixedly connected to the outer wall of the fixed shell 12. One end of the second water inlet pipe 14 is fixedly connected and communicated with the outer wall of the fixed shell 12. One end of the first transmission rod 122 is fixedly connected to a first bevel gear 123. A third transmission rod 52 is rotatably connected inside the support pipe 11. A second bevel gear 54 and a third bevel gear 53 are fixedly connected to the third transmission rod 52. The second bevel gear 54 meshes with the first bevel gear 123. A second transmission rod 5 is rotatably connected to the inner lower surface of the outer shell 1. A fourth bevel gear 51 is fixedly connected to the second transmission rod 5. The fourth bevel gear 51 meshes with the third bevel gear 53. A limiting rod 55 is fixedly connected inside the third transmission rod 52. A tooth groove 435 is provided on the lower surface of the turntable 43. The size of the tooth groove 435 matches the size of the limiting rod 55.

[0025] Specifically, when in a rainstorm, a large amount of rainwater enters the inside of the fixed shell 12 through the first water inlet pipe 13. The rainwater washes the impeller 121 to rotate. Subsequently, the rainwater enters the inside of the outer shell 1 through the second water inlet pipe 14. The impeller 121 drives the first transmission rod 122 to rotate. The first transmission rod 122 drives the first bevel gear 123 to rotate. The first bevel gear 123 meshes with the second bevel gear 54, causing the third transmission rod 52 to rotate. The third transmission rod 52 simultaneously drives the third bevel gear 53 to rotate. The third bevel gear 53 meshes with the fourth bevel gear 51. The fourth bevel gear 51 drives the second transmission rod 5 to rotate. The second transmission rod 5 drives the limiting rod 55 to rotate. The limiting rod 55 meshes with the tooth groove 435 below the turntable 43, enabling the turntable 43 to rotate. The turntable 43 drives the push plate 433 to rotate. The push plate 433 can push the soil block to rotate and cooperate with the cutting blade 412 to break up the soil block.

[0026] As Figure 3 and Figure 4As shown, a handle 44 is rotatably connected to the upper surface of the sewage interception basket 4, a positioning rod 21 is fixedly connected to the upper surface of the diversion plate 2, a clamping groove 211 is arranged on the surface of the positioning rod 21, and the rotated handle 44 enters the inside of the clamping groove 211. The clamping groove 211 limits the handle 44, so that the diversion plate 2 and the sewage interception basket 4 are fixed to each other. A positioning block 45 is fixedly connected to the sewage interception basket 4, and the internal dimension of the positioning block 45 matches the dimension of the positioning rod 21. Specifically, when it is necessary to disassemble the sewage interception basket 4 and clean the impurities inside it, the handle 44 can be rotated. The handle 44 rotates and disengages from the clamping groove 211 on the positioning rod 21. At this time, the handle 44 is pulled to drive the sewage interception basket 4 to rise. The rising of the sewage interception basket 4 drives the positioning block 45 to disengage from the positioning rod 21. Subsequently, the sewage interception basket 4 drives the turntable 43 to rise. After the turntable 43 drives the tooth groove 435 to disengage from the limiting rod 55, the sewage interception basket 4 can be disassembled and the impurities inside it can be cleaned.

[0027] As Figures 8-13 As shown, a moving rod 414 is slidably connected inside the fixing frame 41. A fixing rod 4142 is fixedly connected to the surface of the moving rod 414. A spiral groove 4111 is arranged on the rotating rod 411. One end of the fixing rod 4142 is slidably connected to the inside of the spiral groove 4111. A moving groove 436 is arranged inside the turntable 43. A limiting plate 431 is fixedly connected to the inner wall of the moving groove 436. A convex block 432 is fixedly connected to the inner lower surface of the moving groove 436. One end of the moving rod 414 is fixedly connected to a sliding rod 4141.

[0028] Specifically, when the push plate 433 drives the soil block to move and contact the cutting piece 412 and press the soil block, after some of the soil blocks are crushed and blocked between the filter grooves 42 by the cutting piece 412, and the small crushed soil blocks will move towards the filter grooves 42 with the flow of rainwater. Since the soil blocks are mostly irregular in shape, when the size of the soil block matches the size of the filter groove 42, the soil block will also be blocked between the cutting piece 412 and the filter groove 42. As time goes by, more and more soil blocks accumulate between the cutting piece 412 and the filter groove 42, which causes the filter groove 42 to be blocked again, and finally leads to the problem of reduced rainwater purification efficiency. To avoid the above problems, the present device is used as follows: Under normal conditions, the slide bar 4141 on the moving rod 414 is located below the limiting plate 431. When the turntable 43 rotates, the turntable 43 drives the moving groove 436 to rotate, and the moving rod 414 slides inside the moving groove 436. At the same time, the slide bar 4141 slides under the limitation of the limiting plate 431. When the moving rod 414 moves to the bump 432, the limiting plate 431 releases the limitation on the slide bar 4141, so that the bump 432 squeezes the moving rod 414. The moving rod 414 slides inside the fixing frame 41, causing the moving rod 414 to drive the fixing rod 4142 to slide inwardly towards the fixing frame 41. The fixing rod 4142 squeezes the spiral groove 4111 on the surface of the rotating rod 411, causing the rotating rod 411 to rotate. The rotating rod 411 drives the cutting blade 412 to rotate inwardly towards the fixing frame 41. The cutting blade 412 rotates and is received inside the fixing frame 41. When the cutting blade 412 rotates, it can break the soil blocks blocking the filter tank 42 and push them to the outside of the sewage interception basket 4, so that the soil blocks can settle at the bottom of the housing 1. Subsequently, the turntable 43 continues to rotate. When one end of the moving rod 414 disengages from the bump 432, at this time, the inclined surface at one end of the limiting plate 431 squeezes the slide bar 4141, causing the slide bar 4141 to drive the moving rod 414 to reset. The moving rod 414 resets and drives the cutting blade 412 to reset.

[0029] The present device can drive the cutting blade 412 to rotate, so that the cutting blade 412 can dredge the soil blocks in the blocked filter tank 42, avoiding the accumulation of soil blocks between the filter tanks 42, resulting in the blockage of the filter tank 42, and ultimately causing the problem of reduced rainwater purification efficiency.

[0030] As Figure 14 and Figure 15 shown, a second seal 415 is fixedly connected to the inner upper surface of the fixing frame 41. A second ratchet ring 4151 is rotatably connected inside the second seal 415. The second ratchet ring 4151 meshes unidirectionally with a first ratchet ring 4121. The first ratchet ring 4121 is fixedly connected to the cutting blade 412. A ratchet 4152 is fixedly connected to the rotating end of the second ratchet ring 4151. A pawl 4153 is rotatably connected inside the second seal 415 through a torsion spring 4154. A first seal 413 is fixedly connected inside the fixing frame 41. One end of the rotating rod 411 is rotatably connected inside the first seal 413. A spring telescopic rod 416 is provided between the first seal 413 and the cutting blade 412. The telescopic end of the spring telescopic rod 416 is rotatably connected to one end of the cutting blade 412. The fixed end of the spring telescopic rod 416 is fixedly connected to the upper surface of the first seal 413.

[0031] Specifically, due to the certain adhesiveness of the soil and the fact that the soil is wetted by rainwater scouring and driving, its adhesiveness is improved. Therefore, when the cutting piece 412 cleans the soil blocks in the filter tank 42, some soil will adhere to the cutting piece 412 and come into contact with sediment subsequently, causing the soil to accumulate on the cutting piece 412. When the accumulated size is relatively large, it will cause the filter tank 42 to be blocked and lead to the problem of reduced subsequent rainwater purification efficiency.

[0032] To avoid the above problems, the specific use of this device is as follows: When the cutting piece 412 rotates and cleans the blocked soil inside the filter tank 42, the cutting piece 412 drives the first ratchet ring 4121 to rotate. The first ratchet ring 4121 rotates below the second ratchet ring 4151. When the cutting plate rotates and completely enters the fixed frame 41, the first ratchet ring 4121 and the second ratchet ring 4151 are in one-way meshing. The first ratchet ring 4121 drives the second ratchet ring 4151 to rotate, and the second ratchet ring 4151 drives the ratchet wheel 4152 to rotate. The ratchet wheel 4152 toggles the pawl 4153 and compresses the torsion spring 4154. When the cutting piece 412 rotates back, the pawl 4153 makes one-way meshing with the ratchet wheel 4152 to limit the second ratchet ring 4151. Subsequently, when the first ratchet ring 4121 rotates back, the second ratchet ring 4151 squeezes the first ratchet ring 4121, causing the first ratchet ring 4121 to drive the cutting piece 412 to squeeze and move towards one end of the spring telescopic rod 416. The cutting piece 412 squeezes the spring telescopic rod 416 and slides on the rotating rod 411. Subsequently, the first ratchet ring 4121 continues to rotate and gets out of the extrusion of the second ratchet ring 4151. At this time, the spring telescopic rod 416 drives the cutting piece 412 to reset and shakes off the soil attached to the surface of the cutting piece 412. Finally, the cutting piece 412 rotates back to the outside of the fixed frame 41 at this time for subsequent crushing operations.

[0033] This device can shake off the sticky soil blocks attached to the surface of the cutting piece 412, avoiding the situation where some soil adheres to the cutting piece 412 and comes into contact with sediment subsequently, causing the soil blocks to accumulate on the cutting piece 412 and leading to the blockage of the filter tank 42 by the soil blocks, thereby causing the problem of reduced subsequent rainwater purification efficiency.

[0034] Working principle: When in heavy rain, a large amount of rainwater enters the interior of the fixed housing 12 through the first water inlet pipe 13, and then the rainwater enters the interior of the housing 1 through the second water inlet pipe 14. The water flow enters the deflector 2 tangentially along the inner wall of the housing 1. At this time, a swirling flow and a radial flow are formed on the deflector 2. The rainwater drives the sediment through the filter slots 42 on the sewage interception basket 4. The heavier impurities such as sediment particles and sediment in the rainwater are thrown towards the inner wall of the housing 1 under the action of centrifugal force and finally fall to the bottom to form a precipitate. The rainwater that has undergone preliminary swirling separation will continue to flow upward. The rainwater flows towards the filter element 31. The interior of the filter element 31 is filled with various filter materials. The filter materials can further filter out the fine particles in the rainwater and simultaneously adsorb and filter substances such as suspended solids, macromolecular organic matter, and colloids in the water. The rainwater treated by the filter element 31 can be discharged through the drain pipe 15. At this time, the purification operation of the rainwater can be completed. When the use is finished, open the sewage discharge pipe 16 and connect a pump to pump out the precipitate at the bottom of the housing 1; A large number of soil blocks carried by the rain scour fall onto the conical block 434 inside the sewage interception basket 4. Due to the inclined surface of the conical block 434, a large number of convex blocks 432 slide towards the inner wall of the sewage interception basket 4. At this time, the turntable 43 below the sewage interception basket 4 rotates. The turntable 43 drives the push plate 433 and the conical block 434 to rotate. The push plate 433 pushes the soil blocks on the conical block 434 to rotate. The soil blocks come into contact with the cutting blades 412 and are pushed by the push plate 433. Since during heavy rain, a large amount of rainwater quickly penetrates into the soil, making the soil structure loose and easy to break, the soil blocks are limited by the cutting blades 412 at this time and are also pushed by the push plate 433. Through the extrusion of the cutting blades 412 and the push plate 433, the soil blocks can be broken. The small pieces of soil generated after the soil blocks are broken float in the rainwater. At this time, the push plate 433 rotates to drive the rainwater to generate a swirling flow. The centrifugal force generated causes the small pieces of soil to be thrown to the inner wall of the sewage interception basket 4, enabling the soil to pass through the filter slots 42 and form a precipitate at the bottom of the housing 1. When the use is finished, open the sewage discharge pipe 16 and connect a pump to pump out the precipitate at the bottom of the housing 1; The turntable 43 drives the push plate 433 and the conical block 434 to rotate. The push plate 433 pushes the soil blocks on the conical block 434 to rotate. The soil blocks come into contact with the cutting blades 412 and are pushed by the push plate 433. Since during heavy rain, a large amount of rainwater quickly penetrates into the soil, making the soil structure loose and easy to break, the soil blocks are limited by the cutting blades 412 at this time and are also pushed by the push plate 433. Through the extrusion of the cutting blades 412 and the push plate 433, the soil blocks can be broken. The small pieces of soil generated after the soil blocks are broken pass through the filter slots 42 and form a precipitate at the bottom of the housing 1; When the turntable 43 rotates, the turntable 43 drives the moving groove 436 to rotate. The moving rod 414 slides inside the moving groove 436. At the same time, the sliding rod 4141 slides under the limit of the limiting plate 431. When the moving rod 414 moves to the convex block 432, the limiting plate 431 releases the limit on the sliding rod 4141, so that the convex block 432 squeezes the moving rod 414. The moving rod 414 slides inside the fixed frame 41, so that the moving rod 414 drives the fixed rod 4142 to slide towards the inside of the fixed frame 41. The fixed rod 4142 squeezes the spiral groove 4111 on the surface of the rotating rod 411, causing the rotating rod 411 to rotate. The rotating rod 411 drives the cutting piece 412 to rotate towards the inside of the fixed frame 41. The cutting piece 412 rotates and is received inside the fixed frame 41. When the cutting piece 412 rotates, it can break the soil block blocking the filter groove 42 and push it to the outside of the sewage interception basket 4, so that the soil block can settle at the bottom of the housing 1. Subsequently, the turntable 43 continues to rotate. When one end of the moving rod 414 disengages from the convex block 432, at this time, one end inclined surface of the limiting plate 431 squeezes the sliding rod 4141, so that the sliding rod 4141 drives the moving rod 414 to reset. The moving rod 414 resets and drives the cutting piece 412 to reset; When the cutting piece 412 rotates and cleans the soil blocked inside the filter groove 42, the cutting piece 412 drives the first ratchet ring 4121 to rotate. The first ratchet ring 4121 rotates below the second ratchet ring 4151. When the cutting plate rotates and completely enters the fixed frame 41, the first ratchet ring 4121 and the second ratchet ring 4151 are in one-way meshing. The first ratchet ring 4121 drives the second ratchet ring 4151 to rotate. The second ratchet ring 4151 drives the ratchet 4152 to rotate. The ratchet 4152 toggles the pawl 4153 and squeezes the torsion spring 4154. When the cutting piece 412 rotates and resets, the pawl 4153 performs one-way meshing on the ratchet 4152, limiting the second ratchet ring 4151. Subsequently, when the first ratchet ring 4121 rotates and resets, the second ratchet ring 4151 squeezes the first ratchet ring 4121, so that the first ratchet ring 4121 drives the cutting piece 412 to squeeze and move towards one end of the spring telescopic rod 416. The cutting piece 412 squeezes the spring telescopic rod 416. Subsequently, the first ratchet ring 4121 continues to rotate and disengages from the extrusion of the second ratchet ring 4151. At this time, the spring telescopic rod 416 drives the cutting piece 412 to reset and shakes off the soil attached to the surface of the cutting piece 412. Finally, the cutting piece 412 rotates and resets to the outside of the fixed frame 41 for subsequent crushing operations; When it is necessary to disassemble the sewage interception basket 4 and clean the impurities inside it, the handle 44 can be rotated. The handle 44 rotates and disengages from the card slot 211 on the positioning rod 21. At this time, pulling the handle 44 drives the sewage interception basket 4 to rise. The rising of the sewage interception basket 4 drives the positioning block 45 to disengage from the positioning rod 21. Subsequently, the sewage interception basket 4 drives the turntable 43 to rise. After the turntable 43 drives the tooth groove 435 to disengage from the limit rod 55, the sewage interception basket 4 can be disassembled and the impurities inside it can be cleaned.
