The water is polluted in the garden landscape area through the use in the life and operation processes, becomes sewage or waste water and can be discharged after being treated; in order to reduce the water disaster degree, rainwater, ice and snow melting water and the like also need to be discharged in time, and only a perfect irrigation system is equipped, the rainwater, the ice and snow melting water and the like can be organically treated and discharged, which is the garden drainage engineering.
The drainage system comprises a water pipeline, a grid plate arranged above the water pipeline and a blockage stopping mechanism arranged on the grid plate and used for preventing leaves from blocking the grid plate, wherein the blockage stopping mechanism comprises a jacking part arranged in a gap of the grid plate, a jacking rod with one end fixedly connected with the jacking part and a driving part fixedly connected to one end of the jacking rod, which is far away from the jacking part, and the jacking rod is rotatably connected with the grid plate, so that the problem that the drainage is not smooth after the grid plate above the water pipeline is blocked by deposits such as leaves is solved, rainwater can overflow the road surface, and the walking and swimming of pedestrians are seriously influenced; however, the invention still has the defects that when the jacking part acts on the dead leaf garbage attached to the grating plate, the jacking part is easily inserted into the dead leaf garbage because the dead leaf is soft in texture, so that the dead leaf garbage is wound at the end part of the jacking part to influence the normal work of the jacking part; so that the technical solution is limited.
In view of this, the present invention provides a drainage system for municipal garden to solve the above technical problems.
Disclosure of Invention
In order to make up the defects of the prior art, the problem that when the accumulated dead-leaf garbage is dredged by the existing municipal garden drainage system is solved, the dead-leaf garbage is easy to wind on a dredging device, and the dredging treatment of a water through pipe is influenced; the invention provides a municipal garden drainage system.
The technical scheme adopted by the invention for solving the technical problems is as follows: the invention relates to a municipal garden drainage system, which comprises a drainage tank, a water service pipe and a pipe cover; the drainage channels are obliquely arranged on two sides of a road surface, a group of water through pipes are uniformly arranged at the bottoms of the drainage channels, the pipe covers are rotatably connected with the tops of the water through pipes, and the bottoms of the water through pipes are communicated with a sewer; a group of water passing grooves are uniformly formed in the upper surface of the pipe cover, and a first rod is arranged on the side wall of each water passing groove; the first rod is rotatably connected with the side wall of the water trough and is connected with the side wall of the water trough through a spring, the width of the first rod is smaller than that of the water trough, a group of dredging rods are uniformly arranged on the upper surface of the first rod, and the end parts of the dredging rods are subjected to round angle treatment and are higher than the upper surface of the pipe cover; the upper surface of the pipe cover is inclined to the bottom surface of the drainage channel, and the highest point of the upper surface of the pipe cover is close to the lowest point of the bottom surface of the drainage channel.
When the garden drainage device works, the drainage grooves are arranged at the two sides of a road with larger gradient in a garden, so that the drainage grooves are inclined to the horizontal plane, and the end parts with lower height of the drainage grooves are communicated with rivers passing through the garden; in the rain weather, rain falling from the road is gathered in the drainage channel and flows into the river along the drainage channel, so that the safety of the road is ensured; when the rainfall is too large in a short time, the rainwater in the drainage groove is accumulated too much, so that the rainwater overflows from the drainage groove and impacts a road, the road surface is easy to be washed away, and the possible pedestrians on the road are threatened; therefore, the water through pipe is arranged at the bottom of the drainage groove of the section where a large amount of rainwater is easy to accumulate, and when a large amount of accumulated rainwater impacts the pipe cover at the top of the water through pipe and flows down from the gap between the first rod and the side wall of the water through groove, the amount of rainwater flowing in the water through groove is reduced, and the rainwater is prevented from overflowing; the flowing rainwater impacts the first rod when passing through the water through groove, so that the first rod is pressed and drives the dredging rod to rotate downwards, and the obstruction of the rainwater flowing through the water through groove is weakened, so that the rainwater can quickly pass through the water through groove, and the water quantity of the flowing rainwater in the drainage groove is further reduced; when the dead leaf garbage in the rainwater is attached to the water trough, the water trough is blocked, the impact on the first rod is weakened and drives the dredging rod to reset and rotate, so that the dead leaf garbage blocked on the water trough is ejected out and separated from the water trough, and then the ejected dead leaf garbage is far away from the water pipe under the impact of flowing rainwater, and the smoothness of the water trough is ensured; the end part of the dredging rod is subjected to fillet treatment, so that when the end part of the dredging rod ejects the dead-leaf garbage, the situation that the dead-leaf garbage is attached to the end part of the dredging rod to affect the drainage effect due to the fact that the acting force of the end part of the dredging rod on the dead-leaf garbage is concentrated and inserted into the dead-leaf garbage is effectively avoided; because the upper surface of the pipe cover is inclined to the bottom surface of the drainage groove, the flowing rainwater is blocked by the pipe cover and the surface of the pipe cover is impacted, so that on one hand, the rainwater impacting the surface of the pipe cover can pass through the water through groove at an accelerated speed, and the water quantity of the flowing rainwater is further reduced; on the other hand, the dead leaf garbage attached to the upper surface of the pipe cover is further separated from the surface of the pipe cover under the impact action, so that the smoothness of a water trough on the pipe cover is ensured; and the flowing rainwater is scattered all around under the impact action, the impact on the first rod is changed constantly, and the first plate swings up and down under the impact action of the change of strength, so that dead leaf garbage attached to the water trough is further removed, and the smoothness of the water trough is ensured.
Preferably, a group of blocking blocks are uniformly arranged on the bottom surface of the drainage groove and close to the water passing pipe, and the impact of sundries in flowing rainwater on the water passing pipe is reduced through the action of the blocking blocks.
When the rainwater drainage device works, flowing rainwater can be contacted with the blocking block when approaching the water service pipe, so that the part of the flowing rainwater, which is close to the bottom surface of the drainage groove, is blocked by the blocking block; the heavy impurities such as stones mixed in the flowing rainwater are concentrated at the position close to the bottom, so that the heavy impurities are hindered by the blocking blocks, one part of the impurities are left in gaps among the blocking blocks, and the other part of the impurities move at a reduced speed and reduced kinetic energy under the action of the blocking blocks; therefore, when the sundries collide with the pipe cover of the water pipe, the impact action on the pipe cover is weakened, and the pipe cover is prevented from being damaged under the impact action of heavy sundries; after the rainwater weather is over, cleaning personnel can remove sundries left in gaps among the blocking blocks, so that the normal function of the blocking blocks is ensured; in addition, the flow velocity of the rainwater is weakened under the action of the blocking blocks, and the continuously distributed blocking blocks enable the flowing rainwater to be wavy, so that the impact action on the upper surface of the pipe cover is changed continuously, and the dead-leaf garbage attached to the upper surface of the pipe cover is removed more thoroughly; and under the impact action of continuous change, the vertical swing amplitude of the first rod is increased, so that the smoothness of a water passing groove on the pipe cover is further ensured.
Preferably, the first plate is mounted on the upper surface of the pipe cover and is rotatably connected with the upper surface of the pipe cover, and the lower surface of the first plate is opposite to the flowing direction of rainwater; the end part of the first plate is connected with the end part of the first rod through an elastic rope, a support rod is arranged in the middle of the lower surface of the first plate, the support rod is rotatably connected with the first plate, a reset elastic sheet is arranged at the joint of the support rod and the surface of the first plate, and the end part of the support rod is embedded into a first groove formed in the middle of the upper surface of the pipe cover.
When the rain water collecting device works, the first plate is inclined to the upper surface of the pipe cover through the supporting action of the supporting rod, when rain water impacts the lower surface of the first plate, the first plate is pressed to rotate, and the end part of the supporting rod is separated from the first groove; the rotating first plate drives the first rod to rotate upwards through the elastic rope, and the dredging rod moves upwards along with the first rod, so that the dead leaf garbage attached to the upper part of the water through groove is further ejected out and is separated from the water through pipe under the impact of flowing rainwater; the wave crest part of the flowing rainwater impacts the first plate because the flowing rainwater is wavy, so that the first plate is strong in impact action and large in rotation amplitude; when the wave trough part impacts the first plate, the impact action on the first plate is weaker, the first rod pulls the elastic rope under the action of the deformation recovery of the connected spring to reset the first plate, the end part of the supporting rod is embedded into the first groove again and slides in the first groove, the supporting rod rotates around the joint of the supporting rod and the first plate under pressure, and when the impact action on the supporting rod is relieved, the supporting rod resets under the action of the resetting elastic sheet; therefore, under the impact of flowing rainwater, the amplitude of the vertical swing of the first rod driven by the first plate is further increased, so that sundries in the water passing groove are further removed; and the rainwater impacting the first plate flows out towards the two sides of the first plate under the blocking action of the first plate, so that sundries in the gap between the first plate and the pipe cover are removed, and the smooth rotation of the first plate is ensured.
Preferably, the parts of the lower surface of the first plate, which are positioned on the two sides of the supporting rod, are symmetrical and are uniformly provided with a group of drainage grooves, and the end parts of the drainage grooves point to the direction close to the side wall of the drainage groove.
During operation, the rainwater of strikeing a board lower surface concentrates down to a board both sides direction outflow under the guide effect in the drainage groove that a board lower surface evenly set up for the impact that the dead leaf rubbish that is located the clearance between a board and the tube cap received further obtains the reinforcing, and consequently the dead leaf rubbish that is located between a board and the tube cap is clear away more thoroughly, further avoids the rotation of a board to receive the hindrance.
Preferably, the dredging rod is inclined to the surface of the first rod, and the end part of the dredging rod is inclined to the direction close to the first plate; the position of the surface of the dredging rod, which is just opposite to the flowing direction of rainwater, is provided with a second groove, and the rainwater is guided to flow on the dredging rod and clean the dredging rod under the action of the second groove.
When the rainwater dredging device works, the end part of the dredging rod inclines towards the direction far away from the flowing direction of rainwater, so that when flowing rainwater enters the dredging rod, the flowing rainwater flows to the end part of the dredging rod along the second groove on the dredging rod and flows from the end part of the dredging rod, and the surface of the dredging rod is cleaned in the flowing process; when the dead leaf garbage is attached to the end part of the dredging rod and is difficult to separate under the blocking action of the end part of the dredging rod, water flowing along the second groove impacts the dead leaf garbage at the end part of the dredging rod, so that the dead leaf garbage is impacted along the direction of the dredging rod and is separated from the dredging rod; and when a board drives a pole and rotates, the contained angle between the mediation pole on a pole and the horizontal plane reduces, consequently during the adnexed dry leaf rubbish of mediation pole tip received the rainwater impact force that flows, can decompose the component increase along mediation pole side, further promotes dry leaf rubbish and breaks away from mediation pole tip, avoids the dry leaf rubbish of adnexed in mediation pole tip to cause the jam of water flowing groove.
Preferably, the second groove is a through groove, a rotating shaft is arranged in the middle of the inner surface of the second groove, a fixing ring is nested on the outer surface of the rotating shaft, a group of impurity removing blades are uniformly arranged on the outer surface of the fixing ring, and the fixing ring is rotatably connected with the outer surface of the rotating shaft; the rotating shaft is eccentrically arranged in the second groove and is positioned on the inner surface of the second groove close to the end part of the dredging rod; the distance between the end part of the impurity removal blade and the rotating shaft is larger than the distance between the rotating shaft and the end part of the dredging rod.
When the rainwater collecting device works, the second groove is a through groove, and when rainwater flows through the first rod and passes through the second groove, impurities such as silt and the like attached to the second groove are removed; rainwater passing through the second groove impacts the surface of the impurity removal blade, and the impurity removal blade is eccentrically arranged, so that the impurity removal blade is unevenly distributed under the impact action of flowing rainwater, and the impurity removal blade smoothly rotates; the rotating impurity removal blade acts on the silt impurities attached to the second groove to ensure that the second groove is kept smooth; and because the interval between edulcoration blade tip and the pivot is greater than the interval between pivot and the mediation pole tip, consequently the edulcoration blade rotates to mediation pole tip and is, edulcoration blade tip stretches out No. two grooves for adnexed dead leaf impurity bumps with the edulcoration blade on the mediation pole tip, thereby makes dead leaf impurity break away from mediation pole tip under the striking effect, thereby makes the mediation pole keep clean, avoids adnexed dead leaf impurity to cause the jam that leads to the water groove on the mediation pole tip.
Preferably, the inner diameter of the fixing ring is larger than the diameter of the rotating shaft, a group of elastic scrapers are uniformly arranged on the inner surface of the fixing ring, and the end parts of the scrapers are arc-shaped; the position that is located the clearance between the edulcoration blade on the solid fixed ring surface evenly is equipped with a set of No. three grooves, the clearance position between No. three grooves and the scraper blade communicates with each other.
When the device works, the inner diameter of the fixing ring is larger, so when the impurity removing blades are stressed to rotate, the fixing ring can smoothly drive the impurity removing blades to rotate around the rotating shaft, rainwater can smoothly penetrate into a gap between the outer surface of the rotating shaft and the inner surface of the fixing ring and play a role in lubrication, and the friction resistance between the fixing ring and the outer surface of the rotating shaft when the fixing ring rotates is reduced; and the scraper blade that solid fixed ring internal surface set up makes and rotates along with solid fixed ring to make the rainwater that is located clearance between solid fixed ring and the pivot rotate under the stirring effect of scraper blade, thereby make silt that mixes some in the rainwater in clearance between solid fixed ring and the pivot flow out through No. three grooves under the effect of pivoted centrifugal force, avoid silt to adhere to at solid fixed ring internal surface and lead to the frictional force increase between solid fixed ring and the pivot, lead to appearing the card between solid fixed ring and the pivot even and die, influence solid fixed ring's rotation.
Preferably, the width of the fixing ring is smaller than that of the second groove, a serrated impurity removing block is arranged at the position, close to the side wall surface of the second groove, of the impurity removing blade, and the impurity removing block is an elastic rubber block.
When the device works, because the width of the fixing ring is smaller, when the fixing ring rotates, the fixing ring drives the impurity removing blades to slide along the rotating shaft in a reciprocating manner under the action of flowing rainwater, on one hand, the rainwater in the gap between the fixing ring and the rotating shaft is accelerated to flow, and the phenomenon that silt is attached to the inner surface of the fixing ring to influence the rotation of the fixing ring is avoided; on the other hand, along with solid fixed ring reciprocating sliding's edulcoration blade contacts with No. two inslot surfaces, the edulcoration piece on the edulcoration blade lateral wall tip makes No. two groove lateral walls receive the scraping effect, has further guaranteed the cleanness in No. two grooves, avoids silt to pile up in No. two grooves and causes the jam in No. two grooves.
The invention has the following beneficial effects:
1. according to the municipal garden drainage system, the flowing rainwater is impacted on the surface of the pipe cover, so that on one hand, the rainwater impacting the surface of the pipe cover can pass through the water through groove at an accelerated speed, and the water quantity of the flowing rainwater is further reduced; on the other hand, the dead leaf garbage attached to the upper surface of the pipe cover is further separated from the surface of the pipe cover under the impact action, so that the smoothness of a water trough on the pipe cover is ensured; and the flowing rainwater is scattered all around under the impact action, the impact on the first rod is changed constantly, and the first plate swings up and down under the impact action of the change of strength, so that dead leaf garbage attached to the water trough is further removed, and the smoothness of the water trough is ensured.
2. According to the municipal garden drainage system, the group of blocking blocks are uniformly arranged on the bottom surface of the drainage groove close to the water through pipe, so that sundries such as stones and the like mixed in flowing rainwater are blocked by the blocking blocks, a part of the sundries are retained in gaps among the blocking blocks, and the other part of the sundries are weakened in moving speed and reduced in kinetic energy under the action of the blocking blocks; and the rainwater is enabled to be wavy under the action of the continuously distributed blocking blocks, so that the vertical swing amplitude of the first rod is increased under the continuously changed impact action, and the smoothness of a water passing groove on the pipe cover is further ensured.

When the rainwater drainage device works, flowing rainwater can contact the obstruction blocks 11 when approaching the water service pipe 2, so that the part of the flowing rainwater, which is close to the bottom surface of the drainage channel 1, is obstructed by the continuously distributed obstruction blocks 11; the heavy impurities such as stones mixed in the flowing rainwater are concentrated at the part close to the bottom, so when the heavy impurities are hindered by the hindering blocks 11, one part of the impurities are remained in the gaps among the hindering blocks 11, and the other part of the impurities move at a reduced speed and a reduced kinetic energy under the action of the hindering blocks 11; therefore, when the sundries collide with the pipe cover 3 of the water pipe 2, the impact action on the pipe cover 3 is weakened, and the pipe cover 3 is prevented from being damaged under the impact action of heavy sundries mixed in rainwater; after the rainwater weather is over, cleaning personnel can clear impurities left in gaps among the obstruction blocks 11, so that the normal function of the obstruction blocks 11 is ensured; in addition, the flow speed of the rainwater is weakened under the action of the blocking blocks 11, and the flowing rainwater is wavy due to the continuously distributed blocking blocks 11, so that the impact action on the upper surface of the pipe cover 3 is changed approximately regularly, and the dead-leaf garbage attached to the upper surface of the pipe cover 3 is removed more thoroughly under the continuously changed rainwater impact action; under the impact action of continuous change, the vertical swing amplitude of the first rod 32 is increased, and the smoothness of the water passing groove 31 on the pipe cover 3 is further ensured.
As a specific embodiment of the present invention, a first plate 4 is installed on the upper surface of the pipe cover 3, the first plate 4 is rotatably connected with the upper surface of the pipe cover 3, and the lower surface of the first plate 4 faces the flowing direction of rainwater; the end of the first plate 4 is connected with the end of the first rod 32 through an elastic rope 41, a support rod 42 is arranged in the middle of the lower surface of the first plate 4, the support rod 42 is rotatably connected with the first plate 4, a reset elastic sheet is arranged at the joint of the support rod 42 and the surface of the first plate 4, and the end of the support rod 42 is embedded into a first groove 34 formed in the middle of the upper surface of the tube cover 3.
When the rain water impacts the lower surface of the first plate 4, the first plate 4 is pressed to rotate, and the end part of the support rod 42 is separated from the first groove 34; the rotating first plate 4 drives the first rod 32 to rotate upwards through the elastic rope 41, and the dredging rod 33 moves upwards along with the first rod 32, so that the dead-leaf garbage attached above the water through groove 31 is further ejected out and is separated from the water through pipe 2 under the impact of flowing rainwater; the wave crest part of the flowing rainwater impacts the first plate 4 because the flowing rainwater is wavy, so that the first plate 4 is strong in impact action and large in rotation amplitude; when the wave trough part impacts the first plate 4, the impact action on the first plate 4 is weaker, and at the moment, the first rod 32 pulls the elastic rope 41 under the action of the deformation recovery of the connected spring, so that the first plate 4 is reset; the end of the supporting rod 42 is embedded into the first groove 34 again and slides in the first groove 34, meanwhile, the supporting rod 42 is pressed to rotate around the joint of the supporting rod 42 and the first plate 4, and after the impact action on the supporting rod 42 is relieved, the supporting rod 42 is reset under the action of the reset elastic sheet; therefore, under the impact of flowing rainwater, the amplitude of the vertical swing of the first plate 4 driving the first rod 32 is further increased, so that sundries in the water trough 31 are further removed; and the rainwater impacting the first plate 4 flows out towards the two sides of the first plate 4 under the blocking action of the first plate 4, so that sundries in the gap between the first plate 4 and the pipe cover 3 are cleared, and the smooth rotation of the first plate 4 is ensured.
As a specific embodiment of the invention, the parts of the lower surface of the first plate 4, which are positioned at the two sides of the support rod 42, are symmetrically and uniformly provided with a group of drainage grooves 43, and the end parts of the drainage grooves 43 point to the direction close to the side wall of the drainage groove 1.
During operation, the rainwater that strikes a 4 lower surfaces of board concentrates on flowing to 4 both sides directions of a board under the guide effect of the drainage groove 43 that a 4 lower surfaces of board evenly set up for the impact that the dead leaf rubbish that is located the clearance between 4 and the tube cap 3 received further obtains the reinforcing, and consequently the dead leaf rubbish that is located between 4 and the tube cap 3 is clear away more thoroughly, further avoids a rotation of 4 board to receive the hindrance.
As a specific embodiment of the present invention, the dredging rod 33 is inclined to the surface of the first rod 32, and the end of the dredging rod 33 is inclined to the direction close to the first plate 4; the position of the surface of the dredging rod 33, which is opposite to the rainwater flowing direction, is provided with a second groove 331, and rainwater is guided to flow on the dredging rod 33 through the action of the second groove 331 and clean the dredging rod 33.
In operation, because the end of the dredging rod 33 is inclined to the direction far away from the flowing direction of rainwater, when flowing rainwater passes through the dredging rod 33, the flowing rainwater flows to the end of the dredging rod 33 along the second groove 331 on the dredging rod 33 and flows from the end of the dredging rod 33, and the surface of the dredging rod 33 is cleaned in the flowing process; when dead-leaf garbage is attached to the end part of the dredging rod 33 and is difficult to separate under the blocking action of the end part of the dredging rod 33, water flow flowing along the second groove 331 impacts the dead-leaf garbage at the end part of the dredging rod 33, so that the dead-leaf garbage is impacted along the direction of the dredging rod 33 and smoothly separates from the dredging rod 33; when the first plate 4 drives the first rod 32 to rotate, the included angle between the dredging rod 33 on the first rod 32 and the flowing direction of rainwater is reduced; therefore, when the dead-leaf garbage attached to the end of the dredging rod 33 is subjected to the impact force of flowing rainwater, the component force in the direction along the dredging rod 33 is increased, the dead-leaf garbage is further pushed to be separated from the end of the dredging rod 33, and the blockage of the water passing groove 31 caused by the dead-leaf garbage attached to the end of the dredging rod 33 is avoided.
As a specific embodiment of the present invention, the second groove 331 is a through groove, a rotating shaft 332 is disposed in the middle of the inner surface of the second groove 331, a fixing ring 333 is nested on the outer surface of the rotating shaft 332, a group of impurity removing blades 334 are uniformly disposed on the outer surface of the fixing ring 333, and the fixing ring 333 is rotatably connected to the outer surface of the rotating shaft 332; the rotating shaft 332 is eccentrically arranged in the second groove 331, and the rotating shaft 332 is positioned on the inner surface of the second groove 331 close to the end part of the dredging rod 33; the distance between the end of the impurity removing blade 334 and the rotating shaft 332 is larger than the distance between the rotating shaft 332 and the end of the dredging rod 33.
During operation, because the second groove 331 is a through groove, when rainwater flows through the first rod 32 and passes through the second groove 331, impurities such as silt and the like attached to the second groove 331 are removed; the rainwater passing through the second groove 331 impacts the surface of the impurity removing blade 334, and the impurity removing blade 334 is eccentrically arranged, so that the impact action of flowing rainwater on the impurity removing blade 334 is unevenly distributed, and the impurity removing blade 334 smoothly rotates; the rotating impurity removal blade 334 acts on the silt impurities attached in the second groove 331 to ensure that the second groove 331 keeps smooth; and because the interval between edulcoration blade 334 tip and the pivot 332 is greater than the interval between pivot 332 and the mediation pole 33 tip, consequently edulcoration blade 334 rotates when dredging pole 33 tip, edulcoration blade 334 tip stretches out No. two grooves 331 for adnexed dead leaf impurity collides with edulcoration blade 334 on the mediation pole 33 tip, thereby make dead leaf impurity break away from dredging pole 33 tip under the striking effect, make mediation pole 33 keep clean, avoid adnexed dead leaf impurity to cause the jam of water channel 31 on the mediation pole 33 tip.
As a specific embodiment of the present invention, the inner diameter of the fixing ring 333 is larger than the diameter of the rotating shaft 332, and a set of elastic scrapers 335 are uniformly arranged on the inner surface of the fixing ring 333, and the ends of the scrapers 335 are arc-shaped; the part of the outer surface of the fixing ring 333, which is positioned in the gap between the impurity removing blades 334, is uniformly provided with a group of third grooves 336, and the third grooves 336 are communicated with the gap between the scrapers 335.
When the device works, because the inner diameter of the fixing ring 333 is larger, when the impurity removing blades 334 are stressed to rotate, the fixing ring 333 can smoothly drive the impurity removing blades 334 to rotate around the rotating shaft 332, rainwater can smoothly permeate into a gap between the outer surface of the rotating shaft 332 and the inner surface of the fixing ring 333 and play a role in lubrication, and the friction resistance between the fixing ring 333 and the outer surface of the rotating shaft 332 when the fixing ring 333 rotates is reduced; and the scrapers 335 arranged on the inner surface of the fixing ring 333 rotate along with the fixing ring 333, and rainwater in the gap between the fixing ring 333 and the rotating shaft 332 rotates under the stirring action of the scrapers 335, so that silt mixed in the rainwater in the gap between the fixing ring 333 and the rotating shaft 332 flows out through the third groove 336 under the action of the rotating centrifugal force, and the phenomenon that the silt is attached to the inner surface of the fixing ring 333 and causes the increase of the friction force between the fixing ring 333 and the rotating shaft 332, even the fixing ring 333 and the rotating shaft 332 are clamped, and the rotation of the fixing ring 333 is influenced is avoided.
In a specific embodiment of the present invention, the width of the fixing ring 333 is smaller than the width of the second groove 331, and the impurity removing blade 334 is provided with a serrated impurity removing block 337 at a position close to the side wall surface of the second groove 331, and the impurity removing block 337 is an elastic rubber block.
During operation, because the width of the fixing ring 333 is small, when the fixing ring 333 rotates, the fixing ring 333 drives the impurity removing blades 334 to slide back and forth along the outer surface of the rotating shaft 332 under the action of flowing rainwater, on one hand, the rainwater flow in the gap between the fixing ring 333 and the rotating shaft 332 is accelerated, and the influence of silt attached to the inner surface of the fixing ring 333 on the rotation of the fixing ring 333 is avoided; on the other hand, along with the fixed ring 333 reciprocating sliding impurity removing blade 334 and the second groove 331 inner surface contact, the impurity removing block 337 on the impurity removing blade 334 side wall end makes the second groove 331 side wall receive the scraping action, further guarantees the cleanness of the second groove 331, avoids silt to pile up in the second groove 331 and cause the jam of the second groove 331.

the drainage channels 1 are arranged at the two sides of a road with larger gradient in gardens, so that the drainage channels 1 are inclined to the horizontal plane, and the lower end parts of the drainage channels 1 are communicated with rivers passing through the gardens; in the rain weather, rain water falling from the road is gathered in the drainage channel 1 and flows into the river along the drainage channel 1, so that the safety of the road is ensured; when the rainfall is too large in a short time, the rainwater in the drainage channel 1 is accumulated too much, so that the rainwater overflows from the drainage channel 1 and impacts the road, the road surface is easy to be washed away, and the possible pedestrians on the road are threatened; therefore, the water through pipes 2 are uniformly arranged at the bottom of the drainage tank 1 at a section where a large amount of rainwater is easy to accumulate, when a large amount of accumulated rainwater impacts the pipe cover 3 at the top of the water through pipe 2, a part of rainwater flows down from a gap between the first rod 32 and the side wall of the water through tank 31, so that the amount of rainwater flowing in the water through tank 31 is reduced, and the rainwater is prevented from overflowing; the flowing rainwater impacts the first rod 32 when passing through the water passing groove 31, so that the first rod 32 is pressed and drives the dredging rod 33 to rotate downwards, and the obstruction caused when the rainwater flows through the water passing groove 31 is weakened, so that the rainwater can quickly pass through the water passing groove 31, and the water quantity of the flowing rainwater in the drainage groove 1 is further reduced; when the dead leaf garbage in the rainwater is attached to the upper part of the water through groove 31, the water through groove 31 is blocked, at the moment, the impact on the first rod 32 is weakened and the dredging rod 33 is driven to reset and rotate, so that the dead leaf garbage blocked on the water through groove 31 is ejected out and separated from the water through groove 31, and then the ejected dead leaf garbage is far away from the water through pipe 2 under the impact of flowing rainwater, and the smoothness of the water through groove 31 is ensured; the end part of the dredging rod 33 is subjected to round angle treatment, so that when dead leaf garbage is ejected out of the end part of the dredging rod 33, the situation that the dead leaf garbage is attached to the end part of the dredging rod 33 to affect the drainage effect due to the fact that the acting force of the end part of the dredging rod 33 on the dead leaf garbage is concentrated and inserted into the dead leaf garbage is effectively avoided; because the upper surface of the pipe cover 3 is inclined to the bottom surface of the drainage channel 1, the flowing rainwater is obstructed by the pipe cover 3 and the surface of the pipe cover 3 is impacted, so that on one hand, the rainwater impacting the surface of the pipe cover 3 can pass through the water passing channel 31 at an accelerated speed, and the water quantity of the flowing rainwater is further reduced; on the other hand, the dead leaf garbage attached to the upper surface of the pipe cover 3 is further separated from the surface of the pipe cover 3 under the impact action, so that the smoothness of the water trough 31 on the pipe cover 3 is ensured; the flowing rainwater is scattered under the impact action, the impact on the first rod 32 is changed constantly, the first plate 4 swings up and down under the impact action of the change of strength, dead leaf garbage attached to the water through groove 31 is further removed, the smoothness of the water through groove 31 is ensured, and meanwhile, the dead leaf garbage attached to the dredging rod 33 on the first plate 4 is removed more thoroughly under the impact action of the rainwater; the flow speed of the rainwater is weakened under the action of the blocking blocks 11, and the flowing rainwater is wavy due to the continuously distributed blocking blocks 11, so that the impact action on the upper surface of the pipe cover 3 is changed regularly, and the dead leaf garbage attached to the upper surface of the pipe cover 3 is removed more thoroughly under the continuously changed rainwater impact action; under the impact action of continuous change, the vertical swing amplitude of the first rod 32 is increased, so that the smoothness of the water passing groove 31 on the pipe cover 3 is further ensured; when rainwater impacts the lower surface of the first plate 4, the wave crest part of flowing rainwater impacts the first plate 4 because the flowing rainwater is wavy, so that the first plate 4 is subjected to stronger impact action and larger rotation amplitude; when the wave trough part impacts the first plate 4, the impact action on the first plate 4 is weaker, and at the moment, the first rod 32 pulls the elastic rope 41 under the action of the deformation recovery of the connected spring, so that the first plate 4 is reset; the end of the supporting rod 42 is embedded into the first groove 34 again and slides in the first groove 34, meanwhile, the supporting rod 42 is pressed to rotate around the joint of the supporting rod 42 and the first plate 4, and after the impact action on the supporting rod 42 is relieved, the supporting rod 42 is reset under the action of the reset elastic sheet; therefore, under the impact of flowing rainwater, the amplitude of the vertical swing of the first plate 4 driving the first rod 32 is further increased, so that sundries in the water trough 31 are further removed; rainwater impacting the first plate 4 flows out towards the two sides of the first plate 4 under the blocking action of the first plate 4, so that sundries in a gap between the first plate 4 and the pipe cover 3 are removed, and the smooth rotation of the first plate 4 is ensured; because the end of the dredging rod 33 is inclined to the direction far away from the flowing direction of rainwater, when flowing rainwater passes through the dredging rod 33, the flowing rainwater flows to the end of the dredging rod 33 along the groove 331 II on the dredging rod 33 and flows from the end of the dredging rod 33, and the surface of the dredging rod 33 is cleaned in the flowing process; when dead-leaf garbage is attached to the end part of the dredging rod 33 and is difficult to separate under the blocking action of the end part of the dredging rod 33, water flow flowing along the second groove 331 impacts the dead-leaf garbage at the end part of the dredging rod 33, so that the dead-leaf garbage is impacted along the direction of the dredging rod 33 and smoothly separates from the dredging rod 33; when the first plate 4 drives the first rod 32 to rotate, the included angle between the dredging rod 33 on the first rod 32 and the flowing direction of rainwater is reduced; therefore, when the dead-leaf garbage attached to the end part of the dredging rod 33 is impacted by flowing rainwater, the component force in the direction along the dredging rod 33 can be increased, the dead-leaf garbage is further pushed to be separated from the end part of the dredging rod 33, and the blockage of the water passing groove 31 caused by the dead-leaf garbage attached to the end part of the dredging rod 33 is avoided; because the second groove 331 is a through groove, when rainwater flows through the first rod 32 and passes through the second groove 331, impurities such as silt and the like attached to the second groove 331 are removed; the rainwater passing through the second groove 331 impacts the surface of the impurity removing blade 334, and the impurity removing blade 334 is eccentrically arranged, so that the impact action of flowing rainwater on the impurity removing blade 334 is unevenly distributed, and the impurity removing blade 334 smoothly rotates; the rotating impurity removal blade 334 acts on the silt impurities attached in the second groove 331 to ensure that the second groove 331 keeps smooth; and because the interval between edulcoration blade 334 tip and the pivot 332 is greater than the interval between pivot 332 and the mediation pole 33 tip, consequently edulcoration blade 334 rotates when dredging pole 33 tip, edulcoration blade 334 tip stretches out No. two grooves 331 for adnexed dead leaf impurity collides with edulcoration blade 334 on the mediation pole 33 tip, thereby make dead leaf impurity break away from dredging pole 33 tip under the striking effect, make mediation pole 33 keep clean, avoid adnexed dead leaf impurity to cause the jam of water channel 31 on the mediation pole 33 tip.
