Description

Technical Field

[0001] The present invention relates to the field of municipal engineering drainage, and more specifically, to a municipal intelligent drainage device and its drainage method. Background Art

[0002] The drainage system is an important infrastructure of modern cities. How to economically and technically optimize the design and reconstruction and expansion of the urban drainage system is an important research topic. In bad weather such as heavy rain, the drainage efficiency of streets and squares directly affects the operation health of the entire city and the entire traffic system; the current drainage solution is to set drainage outlets around the streets and squares, and manhole covers are placed on the drainage outlets, and the water flow enters the drainage system after passing through the manhole covers.

[0003] Existing patent (Publication No.: CN109056976B) discloses a municipal intelligent drainage device. This municipal intelligent drainage device includes a drainage outlet and a cover plate, and a permanent magnet piece is embedded in the cover plate; guiding sliding grooves are symmetrically arranged in a circumferential direction on the outer periphery of the drainage outlet; a transmission rod is connected between the guiding sliding grooves and the cover plate; a control cavity communicating with the outside is further arranged on the outer periphery of the drainage outlet, and a control bar is arranged in the control cavity. One end of the control bar is fixedly connected to the control cavity, and the other end is fixedly connected to a permanent magnet starting block; the permanent magnet starting block and the permanent magnet piece repel each other with the same pole; the control bar is made of a water-absorbing and swelling material, and the control bar can expand radially along the drainage outlet after absorbing water; the drainage device has a novel structure and a unique principle, and can intelligently open and close the drainage outlet, which can not only ensure the water flow discharge, but also prevent impurities from accumulating, effectively avoid the blockage, decay and odor generation of the drainage outlet, and effectively improve the environment of municipal streets and squares.

[0004] Although the above patent can ensure the water flow discharge and effectively improve the environment of municipal streets and squares, there are still the following deficiencies:

[0005] There are many heavy rain days in coastal cities. During heavy rain days, the water flow on the ground is large. At this time, various impurities on the ground flow together with the water flow. When the impurities contact the side wall of the filter screen ring, under the action of water pressure, the impurities will adhere to the surface of the screen ring, resulting in the blockage of the screen ring. Therefore, the drainage rate is reduced, resulting in the accumulation of water on the ground, so that the water surface on the ground rises rapidly, resulting in the manhole cover being submerged below the water surface. Therefore, when a passerby rides a bicycle past the manhole cover, it is easy to be tripped; and the visibility is poor on rainy days, so it is necessary to get very close to see the manhole cover, resulting in a shortened reaction time and increasing the probability of cyclists falling.

[0029] (3) Under the action of the partition plate, push plate, diversion plate, collection box, and manhole cover, this solution can drive the filter barrel to rotate through the rotation of the manhole cover, so that the impurities attached to the outer wall of the filter barrel are impacted by the water flow and separated from the filter barrel, thereby ensuring the effective filtration area of the filter barrel and playing a role in improving the drainage effect.

[0043] Embodiment 1:

[0044] Please refer to Figures 1-6 , a municipal intelligent drainage device and its drainage method, including a drain pipe 1. A first bracket 2 is vertically slidably installed in the drain pipe 1. A filter barrel 3 is fixedly sleeved on the outer wall of the first bracket 2. A manhole cover 4 that cooperates with the inner wall of the drain pipe 1 is horizontally and fixedly installed at the top end of the filter barrel 3;

[0045] A chute is horizontally opened on the side wall of the drain pipe 1. A first water inlet communicating with the outside is opened on the top wall of the chute. A first magnet 5 is movably arranged in the chute. A water-absorbing and expanding strip 6 is fixedly installed between the side wall of the chute far from the filter barrel 3 and the first magnet 5. A second magnet 7 that repels the first magnet 5 is fixedly embedded on the manhole cover 4;

[0046] A groove is opened on the top wall of the manhole cover 4. A floating box 8 made of a transparent material is movably arranged in the groove. A mounting rod 9 is vertically movably installed on the floating box 8. Red light lamps 10 are uniformly and fixedly installed on the side wall of the mounting rod 9 from top to bottom. A triggering mechanism cooperating with the red light lamps 10 is arranged on the floating box 8. A first telescopic rod 11 is vertically and fixedly installed on the bottom wall of the manhole cover 4. The output end of the first telescopic rod 11 is fixedly connected to the bottom wall of the floating box 8, and a driving mechanism for driving the manhole cover 4 to rotate is arranged on the drain pipe 1.

[0047] The driving mechanism includes a funnel 12 fixedly installed in the drain pipe 1. The inner diameter of the funnel 12 gradually decreases from top to bottom. A second bracket 13 is fixedly installed at the bottom end of the funnel 12. A second telescopic rod 14 is vertically rotatably inserted on the second bracket 13. The output end of the second telescopic rod 14 is fixedly connected to the center of the manhole cover 4, and baffles 15 are uniformly and obliquely fixedly installed on the part of the second telescopic rod 14 below the second bracket 13.

[0048] The triggering mechanism includes a waterproof switch 16 fixedly installed on the bottom wall of the floating box 8. The waterproof switch 16 is electrically connected to the red light lamps 10, and a storage battery 17 electrically connected to the waterproof switch 16 is detachably installed in the floating box 8.

[0049] During rainstorms, rainwater on high-lying ground flows towards low-lying ground. During the flow of rainwater, under the action of the impact force, impurities on the ground flow along with the rainwater. When the rainwater passes through the filter barrel 3, the impurities will adhere to the surface of the filter barrel 3, resulting in a reduction in the effective area of the filter barrel 3, thus reducing the filtering effect, and consequently reducing the drainage efficiency, leading to a rapid rise in the water level of the low-lying ground and submerging the manhole cover 4; especially at night during rainy days, the visibility is poor, so the field of vision of cyclists is small, and the position of the manhole cover 4 cannot be observed in the distance. Only when approaching the manhole cover 4 can the manhole cover 4 be discovered. However, when approaching the manhole cover 4, the cyclist is relatively close to the manhole cover 4, so the time available for making an evasive reaction is short, increasing the probability of the cyclist falling. Therefore, the light emitted by the red light lamp 10 with strong penetrability is used to indicate the position of the manhole cover 4 to the cyclist, reducing the probability of the cyclist falling due to hitting the manhole cover 4.

[0050] When it is not raining, the top wall of the floating box 8 is on the same plane as the top wall of the manhole cover 4. The waterproof switch 16 is squeezed by the floating box 8, so the red light lamp 10 is powered off and the water-absorbing expansion strip 6 is in a contracted state. At this time, the first magnet 5 is located at one end of the chute away from the inner wall of the drain pipe 1; during rainstorms, rainwater passes through the water inlet and enters the chute. At this time, the water-absorbing expansion strip 6 absorbs water and expands, pushing the first magnet 5 to move along the chute. The first magnet 5 gradually approaches the second magnet 7, and the repulsive force received by the second magnet 7 gradually increases. When the first magnet 5 moves below the second magnet 7, the repulsive force between the first magnet 5 and the second magnet 7 reaches the maximum value. Under the combined action of the repulsive force and the buoyancy of the manhole cover 4, the manhole cover 4 moves upward and drives the first bracket 2 to move upward. At this time, the bottom wall of the manhole cover 4 is separated from the drain pipe 1, and the external water flow passes through the filter barrel 3 and flows along the drain pipe 1, thus preventing surface water accumulation, and the filter barrel 3 can prevent ground impurities from flowing into the drain pipe 1, playing a role in preventing the drain pipe 1 from being blocked.

[0051] As the content of impurities adhering to the surface of the filter barrel 3 increases, the effective area of the filter barrel 3 gradually decreases. At this time, the water level above the manhole cover 4 rises. Since the rising height of the manhole cover 4 is limited, the manhole cover 4 will be submerged in the water. At this time, under the action of the buoyancy, the floating box 8 floats up from the groove and under the action of the first telescopic rod 11, the floating box 8 will always float on the water surface. At the moment when the floating box 8 moves upward, the waterproof switch 16 will no longer be squeezed, so the circuit between the red light lamp 10 and the battery 17 is conducted. At this time, the red light lamp 10 is powered on and emits light. Since the penetrability of red light is strong, the position of the manhole cover 4 can be known when the cyclist is at a relatively far position from the floating box 8, so that the cyclist can turn in time to avoid the manhole cover 4, reducing the probability of the cyclist falling due to emergency braking or sharp turning.

[0052] Since the funnel 12 is installed in the drain pipe 1, the water flow in the drain pipe 1 will flow downward along the inner wall of the funnel 12. At this time, the water flow impacts the surface of the baffle 15, and the angle between the baffle 15 and the horizontal plane is 45°. At this time, the baffle 15 receives a downward impact force. Under the action of the impact force, the baffle 15 has a tendency to move horizontally. Since the baffle 15 is fixedly connected to the second telescopic rod 14, the baffle 15 with a tendency to move horizontally will drive the second telescopic rod 14 to rotate. Therefore, the manhole cover 4 fixedly connected to the output end of the second telescopic rod 14 also starts to rotate. And the first telescopic rod 11 is fixedly connected to the manhole cover 4. Therefore, the floating box 8 fixedly connected to the output end of the first telescopic rod 11 also rotates with the manhole cover 4. Therefore, the light emitted by the red light 10 is in a shaking state, thus playing a role in attracting the attention of cyclists.

[0053] When the accumulated water on the ground is completely drained, the water absorbed by the water-absorbing and expanding strip 6 gradually evaporates. Therefore, the water-absorbing and expanding strip 6 resumes its original state and drives the first magnet 5 to reset. At this time, under the action of gravity, the manhole cover 4 resets, thus playing a role in preparing for drainage again.

[0054] Specifically, as Figure 1 shown, it further includes: a collection box 18 with an open top. A feed pipe 19 communicating with the drain pipe 1 is fixedly inserted on the side wall of the collection box 18. And a conduit 20 communicating with the drain pipe 1 is fixedly inserted on the side wall of the collection box 18. And a filter screen 21 matching with the conduit 20 is fixedly embedded on the inner wall of the collection box 18. A support rod 22 is vertically and fixedly installed on the inner wall of the funnel 12. The top of the support rod 22 is fixedly installed with a guide plate 23. The side wall of the guide plate 23 on the side close to the feed pipe 19 is an arc surface. A partition plate 24 is horizontally and fixedly installed on the inner wall of the drain pipe 1 at a position above the guide plate 23. The side wall of the partition plate 24 is attached to the outer wall of the filter barrel 3. And a push plate 25 with a side wall attached to the inner wall of the drain pipe 1 is uniformly and vertically fixedly installed on the side wall of the filter barrel 3.

[0055] Since the filter barrel 3 is sleeved on the first bracket 2, the inner diameter of the drain pipe 1 is larger than the outer diameter of the filter barrel 3. When impurities adhere to the outer wall of the filter barrel 3, under the action of gravity, the impurities gradually move downward along the outer wall of the filter barrel 3 and reach the bottom of the filter barrel 3; when water flows into the space between the inner wall of the drain pipe 1 and the outer wall of the filter barrel 3, some of the water flows impact the surface of the filter barrel 3, and some of the water drops onto the top wall of the partition plate 24 and then impacts the filter barrel 3. The water flowing through the top wall of the partition plate 24 drops downward onto the guide plate 23 after passing through the filter barrel 3 and flows along the side wall of the guide plate 23. Since the side wall of the guide plate 23 close to the collection box 18 is an arc surface, when the water flowing along the guide plate 23 separates from the guide plate 23, the water still maintains its original motion state. Therefore, the water flowing through the inner wall of the filter barrel 3 impacts the outer wall of the filter barrel 3 between the collection box 18 and the guide plate 23 under the action of the partition plate 24. At this time, the impurities attached to the outer wall of the filter barrel 3 are separated from the filter barrel 3 under the action of the impact force and flow into the collection box 18 along the feed pipe 19 with the water flow. And the water in the collection box 18 gradually penetrates into the drain pipe 1 through the conduit 20 and the filter screen 21. Therefore, the water flow containing impurities can continuously flow into the collection box 18 along the feed pipe 19; under the action of the baffle 15 and the second telescopic rod 14, the manhole cover 4 continuously drives the first bracket 2 and the filter barrel 3 to rotate. During the rotation of the filter barrel 3, under the action of the push plate 25, the impurities attached to the outer wall of the filter barrel 3 also rotate with the filter barrel 3. Therefore, the impurities on the outer wall of the filter barrel 3 will all move to the position between the guide plate 23 and the feed pipe 19. Therefore, the impurities on the outer wall of the filter barrel 3 can be cleaned in time, keeping the filter barrel 3 unobstructed and ensuring that rainwater can pass through the filter barrel 3.

[0056] Specifically, as Figure 1 , Figure 3 shown, a third bracket 26 is fixedly installed inside the conduit 20. A striking rod 27 is horizontally movably inserted on the third bracket 26. The striking rod 27 penetrates through the conduit 20 and extends into the drain pipe 1. A slope block 28 is vertically fixedly installed on the top wall of the end of the striking rod 27 located inside the drain pipe 1. The end of the slope block 28 close to the conduit 20 is a slope surface. A second spring 29 is fixedly installed between the striking rod 27 and the third bracket 26. And clamping rods 30 are evenly and horizontally fixedly installed on the side wall of the second telescopic rod 14. A push rod 31 that cooperates with the slope block 28 is fixedly installed on the bottom wall of the clamping rod 30.

[0057] In the initial state, under the action of the second spring 29, the impact rod 27 is in close contact with the filter screen 21. During the rotation of the second telescopic rod 14, the second telescopic rod 14 drives the clamping rod 30 to rotate together. At this time, the clamping rod 30 drives the push rod 31 to rotate together. During the rotation of the clamping rod 30, the push rod 31 gradually approaches the inclined block 28. When the push rod 31 contacts the inclined block 28, the push rod 31 exerts a thrust on the inclined surface of the inclined block 28, and the thrust is decomposed in the horizontal direction. Under the action of the horizontal component force, the inclined block 28 drives the impact rod 27 to move away from the conduit 20, and the second spring 29 is stretched. When the push rod 31 is disengaged from the inclined block 28, the second spring 29 resets and drives the impact rod 27 to move towards the filter screen 21. When the second spring 29 is fully reset, the impact rod 27 impacts the filter screen 21. At this time, the impact force received by the filter screen 21 is transmitted to the impurities attached to the surface of the filter screen 21, and the impact force of the water flow on the impurities cancels out the impact force of the impact rod 27 on the impurities, thereby reducing the force on the impurities in the horizontal direction. At this time, under the action of gravity, the impurities fall downward along the surface of the filter screen 21. Therefore, the water in the collection box 18 can be drained in time, which plays a role in ensuring that the water flow carrying impurities can enter the collection box 18.

[0058] Specifically, as Figure 1 shown, a cover plate 32 is detachably installed at the top end of the collection box 18, and a support plate 33 is movably arranged in the collection box 18. A pull rod 34 whose top end extends to the bottom wall of the cover plate 32 is vertically and fixedly installed on the top wall of the support plate 33.

[0059] When the impurities flow along the feed pipe 19 into the collection box 18, the impurities fall on the top wall of the support plate 33. At this time, as the number of heavy rains increases, the amount of impurities on the top wall of the support plate 33 gradually increases. Therefore, maintenance personnel need to clean the collection box 18. During the cleaning process, the staff holds the handle on the top wall of the cover plate 32 and applies an upward pulling force to the handle. An installation groove is formed on the top wall of the cover plate 32, and the handle is hinged to the bottom wall of the installation groove, which can prevent the handle from protruding and plays a role in ensuring the flatness of the ground. Thus, the cover plate 32 can be taken out, and then the pull rod 34 is pulled upward, so as to drive the support plate 33 to move upward through the pull rod 34. During the upward movement of the support plate 33, the impurities on the top wall of the support plate 33 move upward together with the support plate 33. Therefore, the staff can take out the impurities, which plays a role in preparing for collecting impurities again.

[0060] Specifically, as Figure 2As shown, the installation rod 9 includes a sleeve rod 901, a guide rod 902 and a first spring 903. The red light lamp 10 is installed on the outer wall of the sleeve rod 901. The bottom end of the guide rod 902 is fixedly connected to the inner bottom wall of the floating box 8. The sleeve rod 901 is vertically and slidably inserted on the guide rod 902. The first spring 903 is sleeved on the guide rod 902, and both ends of the first spring 903 are fixedly connected to the sleeve rod 901 and the inner bottom wall of the floating box 8 respectively, and the first telescopic rod 11 is made of rubber material.

[0061] During heavy rain, the shaking amplitude of the road surface water is relatively large. Since the first telescopic rod 11 made of rubber material has elasticity, the floating box 8 will also shake when the water surface shakes. During the shaking process of the floating box 8, the sleeve rod 901 shakes up and down under the action of the first spring 903, further expanding the swinging amplitude of the red light lamp 10, which plays a role in attracting the attention of cyclists.

[0062] Specifically, as Figure 2 shown, an elastic membrane 35 is fixedly installed between the bottom wall of the floating box 8 and the side wall of the groove, and the elastic force of the elastic membrane 35 is less than the gravity of the floating box 8.

[0063] When it does not rain, the floating box 8 is located in the groove. At this time, the floating box 8 exerts pressure on the elastic membrane 35, and the elastic membrane 35 deforms, and the elastic membrane 35 is tightly clamped between the waterproof switch 16 and the floating box 8, thus playing a role in preventing the switch from being damaged by moisture; when the floating box 8 floats on the water surface, the elastic membrane 35 is stretched, so as to prevent impurities in the water from entering the groove, playing a role in ensuring that the floating box 8 can be reset.

[0064] Specifically, as Figure 2 shown, a solar panel 36 is fixedly embedded on the inner top wall of the floating box 8, and the solar panel 36 is electrically connected to the storage battery 17.

[0065] Since the floating box 8 is made of transparent material, in sunny days, sunlight can pass through the top wall of the floating box 8 and irradiate on the surface of the solar panel 36. At this time, the solar panel 36 starts to generate electricity, and the electric energy generated by the solar panel 36 is transmitted to the storage battery 17, thus playing a role in charging the storage battery 17. Therefore, there is no need to frequently charge the storage battery 17, reducing the workload of maintenance personnel and playing a role in saving labor costs.

[0066] The present invention also provides a use method of a municipal intelligent drainage device, including the following steps;

[0067] S1. Rainwater passes through the water inlet and enters the chute. The water-absorbing and expanding strip 6 expands and pushes the first magnet 5 to move along the chute. Then the second magnet 7 drives the manhole cover 4 and the filter barrel 3 to move upward. When the filter barrel 3 is blocked, the depth of the ground water increases. Under the action of buoyancy, the floating box 8 floats on the water surface and the red light lamp 10 starts to work, so as to be able to prompt cyclists to take timely evasive action;

[0068] S2. The water flow passing through the filter barrel 3 flows along the inner wall of the funnel 12 and impacts the baffle 15. At this time, the baffle 15 drives the second telescopic rod 14 to rotate, and the second telescopic rod 14 drives the well cover 4 to rotate, thereby being able to drive the floating box 8 to rotate. During the rotation of the floating box 8, it plays a role in attracting the attention of cyclists, so that cyclists can timely discover the position of the well cover 4.

[0069] S3. The water flow flowing along the side wall of the guide plate 23 impacts the impurities attached to the outer wall of the filter barrel 3, causing the impurities to break away from the contact with the filter barrel 3, thereby ensuring that the surface water can be drained away in time.

[0070] Working principle: During a rainstorm, the rainwater on the high - terrain ground flows towards the low - terrain ground. During the flow of the rainwater, under the action of the impact force, the impurities on the ground flow together with the rainwater. When the rainwater passes through the filter barrel 3, the impurities will adhere to the surface of the filter barrel 3, resulting in a reduction in the effective area of the filter barrel 3, so that the filtering effect is reduced, and thus the drainage efficiency is reduced. As a result, the water level on the low - terrain ground rises rapidly and submerges the well cover 4; especially at night during rainy days, the visibility is poor, so the visual range of cyclists is small. They cannot observe the position of the well cover 4 from a distance and can only discover the well cover 4 when approaching it. However, when approaching the well cover 4, the cyclists are relatively close to the well cover 4, so the time available for making a risk - avoidance reaction is short, which increases the probability of cyclists falling. Therefore, the light emitted by the red light lamp 10 with strong penetrability is used to prompt the position of the well cover 4 for cyclists, reducing the probability of cyclists falling due to hitting the well cover 4.

[0071] When it is not raining, the top wall of the floating box 8 is in the same plane as the top wall of the well cover 4, and the waterproof switch 16 is squeezed by the floating box 8. Therefore, the red light lamp 10 is powered off and the water - absorbing expansion strip 6 is in a contracted state. At this time, the first magnet 5 is located at one end of the sliding groove away from the inner wall of the drain pipe 1; during a rainstorm, the rainwater passes through the water inlet and enters the sliding groove. At this time, the water - absorbing expansion strip 6 absorbs water and expands, and pushes the first magnet 5 to move along the sliding groove. The first magnet 5 gradually approaches the second magnet 7, and the repulsive force received by the second magnet 7 gradually increases. When the first magnet 5 moves below the second magnet 7, the repulsive force between the first magnet 5 and the second magnet 7 reaches the maximum value. Under the combined action of the repulsive force and the buoyancy of the well cover 4, the well cover 4 moves upward and drives the first bracket 2 to move upward. At this time, the bottom wall of the well cover 4 is separated from the contact with the drain pipe 1, and the external water flow passes through the filter barrel 3 and flows along the drain pipe 1, thereby preventing surface water accumulation. And under the action of the filter barrel 3, it can prevent the ground impurities from flowing into the drain pipe 1, playing a role in preventing the drain pipe 1 from being blocked.

[0072] As the content of impurities attached to the surface of the filter barrel 3 increases, the effective area of the filter barrel 3 gradually decreases. At this time, the water level above the manhole cover 4 rises. Since the rising height of the manhole cover 4 is limited, the manhole cover 4 will be submerged in the water. At this time, under the action of buoyancy, the floating box 8 floats up from the groove and under the action of the first telescopic rod 11, the floating box 8 will always float on the water surface. At the moment when the floating box 8 moves upward, the waterproof switch 16 will no longer be squeezed. Therefore, the circuit between the red light 10 and the battery 17 is turned on. At this time, the red light 10 is powered on and emits light. Since the penetration of red light is relatively strong, when the cyclist is at a position far from the floating box 8, he can find out the position of the manhole cover 4.

[0073] Since the funnel 12 is installed in the drain pipe 1, the water flow in the drain pipe 1 will flow downward along the inner wall of the funnel 12. At this time, the water flow impacts the surface of the baffle 15, and the included angle between the baffle 15 and the horizontal plane is 45°. At this time, the baffle 15 receives a downward impact force. Under the action of the impact force, the baffle 15 has a tendency to move horizontally. Since the baffle 15 is fixedly connected to the second telescopic rod 14, the baffle 15 with a tendency to move horizontally will drive the second telescopic rod 14 to rotate. Therefore, the manhole cover 4 fixedly connected to the output end of the second telescopic rod 14 also starts to rotate. And the first telescopic rod 11 is fixedly connected to the manhole cover 4. Therefore, the floating box 8 fixedly connected to the output end of the first telescopic rod 11 also rotates with the manhole cover 4. Therefore, the light emitted by the red light 10 is in a shaking state, thus playing a role in attracting the attention of cyclists.

[0074] When the local accumulated water is completely drained, the water absorbed by the water-absorbing and expanding strip 6 gradually evaporates. Therefore, the water-absorbing and expanding strip 6 resumes its original state and drives the first magnet 5 to reset. At this time, under the action of gravity, the manhole cover 4 resets.

[0075] In heavy rain, the amplitude of the accumulated water on the road surface shakes greatly. Since the first telescopic rod 11 made of rubber material has elasticity, the floating box 8 will also shake when the water surface shakes. During the shaking process of the floating box 8, the sleeve rod 901 shakes up and down under the action of the first spring 903, further expanding the swinging amplitude of the red light 10.

[0076] When it does not rain, the floating box 8 is located in the groove. At this time, the floating box 8 applies pressure to the elastic membrane 35, and the elastic membrane 35 deforms. And the elastic membrane 35 is tightly clamped between the waterproof switch 16 and the floating box 8, thus playing a role in preventing the switch from being damaged by moisture. When the floating box 8 floats on the water surface, the elastic membrane 35 is stretched, so as to prevent impurities in the water from entering the groove.

[0077] Since the floating box 8 is made of transparent material, sunlight can pass through the top wall of the floating box 8 and shine on the surface of the solar panel 36 on sunny days. At this time, the solar panel 36 starts to generate electricity, and the electric energy generated by the solar panel 36 is transmitted to the storage battery 17, thus playing a role in charging the storage battery 17. Therefore, there is no need to frequently charge the storage battery 17.

[0078] Since the filter barrel 3 is sleeved on the first bracket 2, the inner diameter of the drain pipe 1 is larger than the outer diameter of the filter barrel 3. When impurities adhere to the outer wall of the filter barrel 3, under the action of gravity, the impurities gradually move downward along the outer wall of the filter barrel 3 and move to the bottom of the filter barrel 3; when water flows into the space between the inner wall of the drain pipe 1 and the outer wall of the filter barrel 3, part of the water flow impacts the surface of the filter barrel 3, and part of the water flow drops onto the top wall of the partition plate 24 and then impacts the filter barrel 3. The water flow passing through the top wall of the partition plate 24 drops downward onto the deflector 23 after passing through the filter barrel 3 and flows along the side wall of the deflector 23. Since the side wall of the deflector 23 close to the collection box 18 is an arc surface, when the water flow flowing along the deflector 23 is separated from the deflector 23, the water flow still maintains its original motion state. Therefore, the water flow impacts the inner wall of the filter barrel 3. Under the action of the partition plate 24, the outer wall of the filter barrel 3 between the collection box 18 and the deflector 23 is not impacted by the water flow. At this time, the impurities adhering to the outer wall of the filter barrel 3 are separated from the filter barrel 3 under the action of the impact force and flow into the collection box 18 along the feed pipe 19 with the water flow. And the water in the collection box 18 gradually penetrates into the drain pipe 1 through the conduit 20 and the filter screen 21. Therefore, the water flow containing impurities can continuously flow into the collection box 18 along the feed pipe 19; under the action of the baffle 15 and the second telescopic rod 14, the manhole cover 4 continuously drives the first bracket 2 and the filter barrel 3 to rotate. During the rotation of the filter barrel 3, under the action of the push plate 25, the impurities adhering to the outer wall of the filter barrel 3 also rotate with the filter barrel 3. Therefore, the impurities on the outer wall of the filter barrel 3 will all move to the part between the deflector 23 and the feed pipe 19. Therefore, the impurities on the outer wall of the filter barrel 3 can be cleaned in time, keeping the filter barrel 3 unobstructed.

[0079] In the initial state, under the action of the second spring 29, the impact rod 27 is in close contact with the filter screen 21. During the rotation of the second telescopic rod 14, the second telescopic rod 14 drives the clamping rod 30 to rotate together. At this time, the clamping rod 30 drives the push rod 31 to rotate together. During the rotation of the clamping rod 30, the push rod 31 gradually approaches the inclined block 28. When the push rod 31 contacts the inclined block 28, the push rod 31 exerts a thrust on the inclined surface of the inclined block 28, and the thrust is decomposed in the horizontal direction. Under the action of the horizontal component force, the inclined block 28 drives the impact rod 27 to move away from the conduit 20, and the second spring 29 is stretched. When the push rod 31 is separated from the inclined block 28, the second spring 29 resets and drives the impact rod 27 to move towards the filter screen 21. When the second spring 29 is fully reset, the impact rod 27 impacts the filter screen 21. At this time, the impact force received by the filter screen 21 is transmitted to the impurities attached to the surface of the filter screen 21, and the impact force of the water flow on the impurities cancels out the impact force of the impact rod 27 on the impurities, thereby reducing the force on the impurities in the horizontal direction. At this time, under the action of gravity, the impurities fall downward along the surface of the filter screen 21. Therefore, the water in the collection box 18 can be drained in time.

[0080] When the impurities flow along the feed pipe 19 into the collection box 18, the impurities fall on the top wall of the support plate 33. At this time, as the number of heavy rainstorms increases, the amount of impurities on the top wall of the support plate 33 gradually increases. Therefore, maintenance personnel need to clean the collection box 18. During the cleaning process, the staff holds the handle on the top wall of the cover plate 32 and applies an upward pulling force to the handle. An installation groove is provided on the top wall of the cover plate 32, and the handle is hinged to the bottom wall of the installation groove, which can prevent the handle from protruding and plays a role in ensuring the flatness of the ground, so that the cover plate 32 can be taken out. Then, the pull rod 34 is pulled upward, so as to drive the support plate 33 to move upward through the pull rod 34. During the upward movement of the support plate 33, the impurities on the top wall of the support plate 33 move upward together with the support plate 33. Therefore, the staff can take out the impurities.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
