Description

Technical Field

[0001] The present invention relates to the technical field of road drainage, and particularly relates to a road drainage device for municipal engineering. Background Art

[0002] Road drainage is an important link to ensure the normal use of roads and the good surrounding environment. In the case of buried pipe drainage, the drainage pipes are buried under the road. After collecting the rainwater on the road surface through facilities such as rainwater inlets, the rainwater flows into the underground drainage pipes, and then the water is transported by gravity to a suitable discharge location, such as rivers, lakes or the total outlet of the urban rainwater pipe network. Road drainage ensures road traffic safety, the normal use of roads and the health of the surrounding environment.

[0003] In the patent document with the publication number CN114197620A, a municipal road drainage structure is disclosed. Impurities are filtered through a filter disc and a filter barrel. When the filter disc and the filter barrel are blocked by impurities, the water level in the filter barrel will gradually rise and promote the buoyancy ball and the vertical rod to rise. The vertical rod will drive the cleaning ring to slide and scrape the impurities attached to the inner wall of the filter barrel, and the vertical rod will drive the slider to rotate in the spiral groove, so that the rotating cylinder drives the scraper to rotate and scrape the impurities attached to the upper surface of the filter disc, making the filter disc and the filter barrel not easily blocked.

[0004] However, after the filter disc and the filter barrel are blocked by impurities, there are many impurities inside them, the friction between the cleaning ring and the impurities in the filter barrel is large, the buoyancy received by the cleaning ring cannot make it move upward, and the filter holes on the filter disc and the filter barrel are blocked, and the cleaning ring cannot extend into the filter holes to dredge the filter disc and the filter barrel.

The impact rod is fixedly installed at the bottom of the filter barrel. The impact rod is located on the rotation path of the impact block. The impact rod passes through the inside of the ring of the vibration ring.

[0013] Optionally, a water outlet hole is formed at the bottom of the water receiving box. A sealing plate is rotatably connected inside the water receiving box. A sealing rubber is fixedly installed at the bottom of the sealing plate. The sealing plate completely covers the water outlet hole.

[0018] Compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0019] In the present invention, through the flow of silt and sewage on the filter barrel, the overall gravity of the filter barrel is continuously changed, and the dynamic balance between the filter barrel and the counterweight is continuously broken, so that the filter barrel shakes continuously to shake the silt into the sludge discharge pipe. The vibration ring cooperates with the filter barrel to change the angle, so that the steel balls inside it move continuously along the wavy flow track to make the vibration ring vibrate, further increasing the vibration frequency to increase the vibration force received by the silt, and at the same time vibrating the silt in the filter holes of the filter barrel out.

[0020] Furthermore, when sewage enters the water receiving box, the balance between the water receiving box and the impact block is broken. At this time, the overall gravity of the water receiving box is greater than that of the impact block, and the impact block rotates and impacts the impact rod, so that the filter barrel receives an impact force to knock off the silt in the filter holes of the filter barrel and prevent the filter holes from being blocked.

[0021] Furthermore, since road drainage is not always required, after the drainage is completed, the silt on the filter barrel dries up. Through the cooperation of the upper pressing plate, the energy storage spring and the lower pressing plate, the moving speed of the lower pressing plate is increased to increase the pressing speed of the spray gun, thereby increasing the spraying speed. The water collected in the water storage chamber is used to wet the mud at the bottom of the filter barrel and in the filter holes, and in combination with the vibration of the filter barrel and the vibration ring, the mud at the bottom of the filter barrel is shaken off. When there is solidified soil in the filter barrel, auxiliary humidification is carried out to dredge the filter barrel. Brief Description of the Drawings

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] Embodiment 1: This embodiment proposes a road drainage device for municipal engineering, as Figure 1 shown, which includes a drain pipe 1. A sludge discharge pipe 2 is fixedly installed on the side of the drain pipe 1, and two symmetrically arranged support blocks 3 are fixedly installed on the top of the drain pipe 1.

[0038] As Figure 2 and Figure 3 shown, an imbalance separation assembly 4 is arranged on the top of the drain pipe 1. The imbalance separation assembly 4 includes a filter barrel 41, a first torsion spring 43, a counterweight, a vibration ring 47, a flow track 48 and steel balls 49. The filter barrel 41 is rotatably connected between the two support blocks 3 through a rotating shaft. The connection between the filter barrel 41 and the support block 3 is elastically connected with the first torsion spring 43. A counterweight is arranged on the arc surface of the filter barrel 41. The counterweight and the filter barrel 41 form a seesaw structure. A vibration ring 47 is fixedly installed at the bottom of the filter barrel 41. The bottom surface of the filter barrel 41 and the vibration ring 47 are both inclined. The filter barrel 41 is located directly above the drain pipe 1.

[0039] An extended diversion plate 44 is fixedly installed at the sludge discharge outlet of the filter barrel 41. The extended diversion plate 44 extends to directly above the sludge discharge pipe 2. The counterweight includes an extension rod 45 and a counterweight block 46. Extension rods 45 are fixedly installed on both sides of the extended diversion plate 44. The end of the extension rod 45 is fixedly installed with the counterweight block 46. The gravity of the counterweight block 46 is heavier than the gravity of the filter barrel 41 and the extension ring 42.

[0040] Road sewage flows through the filter barrel 41. A sludge discharge outlet facing the sludge discharge pipe 2 is opened on the arc surface of the filter barrel 41. After the road sewage falls on the filter barrel 41, the sludge and sewage are separated through the filter barrel 41. The sewage directly falls into the drain pipe 1 through the filter holes of the filter barrel 41, while the sludge remains in the filter barrel 41. Due to the inclined setting of the filter barrel 41, the sludge will slide along the inclined surface of the filter barrel 41 under the action of gravity and finally fall into the sludge discharge pipe 2.

[0041] Since the gravity of the counterweight block 46 is heavier than the gravity of the filter barrel 41 and the extension ring 42, the height of the counterweight block 46 is lower than the height of the filter barrel 41. However, due to the existence of the sludge and sewage remaining on the filter barrel 41, the overall gravity of the filter barrel 41 changes, so that the seesaw formed by the counterweight block 46 and the filter barrel 41 shakes continuously, resulting in the continuous change of the friction force between the sludge on the filter barrel 41 and the filter barrel 41, facilitating the sliding of the sludge and avoiding the sludge from drying on the filter barrel 41. At the same time, due to the existence of the first torsion spring 43, the shaking frequency is further increased.

[0042] As Figure 4 and Figure 5As shown, there is an angle between the top surface of the vibration ring 47 and the horizontal plane, and there is an angle between the bottom surface of the filter barrel 41 and the horizontal plane. The vibration ring 47 adopts a circular ring structure, and the vibration ring 47 is misaligned with the filter holes at the bottom of the filter barrel 41. A flow track 48 is provided inside the vibration ring 47, and the steel balls 49 slide at the flow track 48 inside the vibration ring 47. The flow track 48 adopts a wavy structure and is connected end to end to form a ring. Two steel balls 49 are provided, and the steel balls 49 slide inside the flow track 48 and impact the vibration ring 47 up and down.

[0043] By continuously changing the angle of the vibration ring 47, the steel balls 49 inside it move continuously. Since the flow track 48 is of a wavy structure, the vibration ring 47 will vibrate during the movement of the steel balls 49, further increasing the vibration frequency.

[0044] An expansion ring 42 is fixedly installed at the top of the filter barrel 41. The expansion ring 42 adopts a flared structure to better receive road sewage. An extended guide plate 44 is fixedly installed at the sludge discharge outlet of the filter barrel 41. The extended guide plate 44 extends directly above the sludge discharge pipe 2, and the extended guide plate 44 guides the sludge.

[0045] In this embodiment, through the flow of sludge and sewage on the filter barrel 41, the overall gravity of the filter barrel 41 is continuously changed, and the dynamic balance between the filter barrel 41 and the counterweight 46 is continuously destroyed, so that the filter barrel 41 shakes continuously, changing the friction between the sludge and the filter barrel 41 to shake the sludge into the sludge discharge pipe 2. And the vibration ring 47 changes the angle along with the filter barrel 41, so that the steel balls 49 inside it move continuously along the wavy flow track 48. Therefore, the vibration ring 47 will vibrate during the movement of the steel balls 49, further increasing the vibration frequency to increase the vibration force received by the sludge and at the same time vibrating the sludge out of the filter holes of the filter barrel 41.

[0046] Embodiment 2: Based on Embodiment 1, this embodiment proposes a road drainage device for municipal engineering, as Figure 5 and Figure 6 shown, an auxiliary vibration member 5 for impacting the filter barrel 41 is provided inside the drain pipe 1. The auxiliary vibration member 5 includes a lever 51, an impact block 52, a water receiving box 53 and an impact rod 56. Both sides of the lever 51 are rotatably connected to the drain pipe 1 through a rotating shaft that restricts the rotation angle. An impact block 52 is fixedly installed at the end of the lever 51. A water receiving box 53 is fixedly installed at the other end of the lever 51. The water receiving box 53 is located directly below the filter barrel 41. An impact rod 56 is fixedly installed at the bottom of the filter barrel 41. The impact rod 56 is located on the rotation path of the impact block 52, and the impact rod 56 passes through the inside of the ring of the vibration ring 47.

[0047] When sewage enters the water receiving box 53, so that the balance between the water receiving box 53 and the impact block 52 is broken, at this time, the overall gravity of the water receiving box 53 is greater than that of the impact block 52, and the impact block 52 rotates and impacts the impact rod 56, so that the filter barrel 41 is subjected to an impact force to knock down the silt in the filter holes of the filter barrel 41 and avoid clogging of the filter holes.

[0048] A water outlet hole 54 is opened at the bottom of the water receiving box 53. A sealing plate 55 is rotatably connected inside the water receiving box 53. A sealing rubber is fixedly installed at the bottom of the sealing plate 55. The sealing plate 55 completely covers the water outlet hole 54. The gravity of the impact block 52 is heavier than the gravity of the water receiving box 53 and the sealing plate 55. The water receiving box 53 is sealed by using the sealing plate 55.

[0049] As Figure 6 and Figure 7 As shown in the figure, a support plate 57 is fixedly installed inside the drain pipe 1. A top column 58 is fixedly installed on the top of the support plate 57. The top column 58 is located on the rotation path of the water receiving box 53. After water accumulates in the water receiving box 53 and its gravity is greater than that of the impact block 52, the water receiving box 53 rotates. The sealing plate 55 inside the water receiving box 53 is pushed open by the top column 58. At this time, the water in the water receiving box 53 flows out. The gravity of the impact block 52 is greater than that of the water receiving box 53 again, and the impact block 52 resets, so that the impact block 52 periodically impacts the impact rod 56.

[0050] In this embodiment, when sewage enters the water receiving box 53, so that the balance between the water receiving box 53 and the impact block 52 is broken, at this time, the overall gravity of the water receiving box 53 is greater than that of the impact block 52, and the impact block 52 rotates and impacts the impact rod 56, so that the filter barrel 41 is subjected to an impact force to knock down the silt in the filter holes of the filter barrel 41 and avoid clogging of the filter holes.

[0051] Embodiment 3: Based on the above Embodiment 1 or 2, this embodiment proposes a road drainage device for municipal engineering, as Figure 5 and Figure 8 shown in the figure, a wetting and dredging member 6 is arranged at the top of the drain pipe 1. The wetting and dredging member 6 includes a bottom block 61, a telescopic rod 62, a support spring 63, a support wedge block 64, a power storage member and a spraying member. The bottom block 61 is fixedly installed at the top of the drain pipe 1. The telescopic rod 62 is fixedly installed at the top of the bottom block 61. The support wedge block 64 is fixedly installed at the top of the telescopic rod 62. A support spring 63 is elastically connected inside the telescopic rod 62 and at the bottom of the support wedge block 64.

[0052] As Figure 8 and Figure 9As shown in the figure, a spraying member is provided at the center of the top of the bottom block 61. A power storage member is provided at the top of the spraying member. The bottom of the sliding portion of the telescopic rod 62 contacts the power storage member. The support wedge 64 is located below the filter barrel 41. The power storage member includes an upper pressure plate 65, a power storage spring 66, a lower pressure plate 67, a power storage limiting plate 69, and a second torsion spring 610. A guide rod is fixedly installed at the top of the bottom block 61. The support wedge 64, the upper pressure plate 65, and the lower pressure plate 67 all slide on the guide rod. The top of the upper pressure plate 65 contacts the sliding portion of the telescopic rod 62. The power storage spring 66 is fixedly installed at the bottom of the upper pressure plate 65. The bottom of the power storage spring 66 is fixedly installed with the lower pressure plate 67. The fixed portion of the telescopic rod 62 is rotationally connected to the power storage limiting plate 69 through a rotating shaft. A second torsion spring 610 is elastically connected between the power storage limiting plate 69 and the telescopic rod 62. The top of the power storage limiting plate 69 supports the lower pressure plate 67. The elastic force of the second torsion spring 610 is stronger than the elastic force of the power storage spring 66.

[0053] The support wedge 64 is located below the filter barrel 41. Under normal conditions, there is no contact between the filter barrel 41 and the support wedge 64. When the filter holes of the filter barrel 41 are blocked and cannot be restored, the overall gravity of the filter barrel 41 increases and is greater than the counterweight 46. At this time, the bottom of the filter barrel 41 presses down on the support wedge 64. The support wedge 64 moves downward and compresses the support spring 63. The support wedge 64 drives the sliding portion of the telescopic rod 62 to move and presses down on the upper pressure plate 65. Since the second torsion spring 610 and the power storage limiting plate 69 support the lower pressure plate 67, the upper pressure plate 65 and the lower pressure plate 67 compress the power storage spring 66. When the elastic force generated by the compression of the power storage spring 66 is greater than the elastic force of the second torsion spring 610, the power storage limiting plate 69 rotates to avoid the lower pressure plate 67. At this time, the elastic force of the power storage spring 66 bounces the lower pressure plate 67 downward, and the lower pressure plate 67 quickly presses down on the spraying member, thereby increasing the spraying pressure and improving the spraying speed.

[0054] The spraying member includes a spray gun 68, a water storage chamber 611, and a nozzle 612. The top of the spray gun 68 is fixedly connected to the lower pressure plate 67. The water storage chamber 611 is fixedly installed inside the drain pipe 1. The water suction pipe of the spray gun 68 extends into the water storage chamber 611. The nozzle 612 is fixedly installed on the side of the bottom block 61. The water spray pipe of the spray gun 68 is communicated with the nozzle 612. The nozzle 612 faces the filter barrel 41.

[0055] Part of the water filtered by the filter barrel 41 is collected through the water storage chamber 611. When the lower pressure plate 67 moves downward to press the spray gun 68, the spray gun 68 sucks the water in the water storage chamber 611 and sprays it out from the nozzle 612 to spray the bottom of the filter barrel 41 to wet the mud at the bottom of the filter barrel 41, and cooperate with the vibration of the above-mentioned filter barrel 41 and the vibration ring 47 to shake off the mud at the bottom of the filter barrel 41.

[0056] Since road drainage is not always required, after the drainage is completed, there is some silt on the filter barrel 41 that fails to enter the sludge discharge pipe 2. Under the condition of no drainage for a long time, the silt on the filter barrel 41 dries up and blocks the filter holes. The wetting and dredging member 6 is used to humidify the dry soil.

[0057] In this embodiment, through the cooperation of the upper pressing plate 65, the energy storage spring 66 and the lower pressing plate 67, the moving speed of the lower pressing plate 67 is increased to increase the pressing speed of the spray gun 68, thereby increasing the spraying speed. The water collected in the water storage chamber 611 is used to wet the sludge at the bottom of the filter barrel 41 and in the filter holes, and in cooperation with the vibration of the filter barrel 41 and the vibration ring 47, the sludge at the bottom of the filter barrel 41 is vibrated off. When there is solidified soil in the filter barrel 41, auxiliary humidification is carried out to dredge the filter barrel 41.

[0058] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
