Description

Technical Field

[0001] The present invention relates to the technical field of sewage outlet silt cleaning, and particularly relates to an automatic cleaning mechanism for silt in road sewage outlets. Background Art

[0002] A road stormwater sewage outlet refers to a facility specifically used for discharging rainwater generated during rainstorms, usually connected to the urban rainwater pipe network system. Its main function is to collect and discharge rainwater from areas such as roofs and roads during rainfall, prevent waterlogging and siltation from causing urban waterlogging, and at the same time maintain the balance of the urban water cycle.

[0003] Road sewage outlet siltation refers to the accumulation of sediment, debris, etc. in road sewage pipes or sewage outlets due to various reasons, affecting the normal operation of the sewage discharge function.

[0004] Existing road sewage outlets lack equipment for dealing with sediment, debris, leaves and branches during rainstorms, resulting in these impurities being directly blocked at the sewage outlet after being washed by rainwater, making it difficult to remove and blocking the water passage, causing siltation and waterlogging. At the same time, the silt and dirt accumulated inside the sewage outlet are difficult to self-clean through the precipitation flow, reducing the drainage efficiency and accelerating the formation of siltation. In addition, the iron grates installed at the sewage outlet will slow down the drainage flow rate, resulting in rainwater accumulation and further increasing the risk of siltation and sewage overflow and waterlogging.

[0005] Therefore, the present application provides an automatic cleaning mechanism for silt in road sewage outlets to meet the needs. Summary of the Invention

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above solution, by setting the silt removal screen assembly, adopting a three-dimensional conical structure and cone nail design, it can effectively prevent the accumulation of sundries such as leaves and branches in a flat state, force the impurities to pass through the screen in a three-dimensional form, reduce the blockage of the water passing gap, improve the instantaneous drainage capacity and prevent siltation; at the same time, the cone nails can pierce flexible sundries such as plastic bags to prevent winding and blockage, and the sewage interception screen automatically cleans the silt on the inner wall of the box body through the scraper during the up and down movement, avoiding secondary blockage, having the functions of automatic interception and cleaning, reducing the frequency of manual maintenance, and actively cleaning the sundries inside the sewage outlet through rainfall prediction, significantly reducing the emergency pressure of the drainage system during sudden heavy rainfall, and realizing efficient anti-siltation and long-term maintenance.

[0020] By setting the drainage and silt removal assembly, adopting the synergistic effect of multi-stage impurity interception and dynamic scouring mechanism, first, the sedimentation tank performs secondary sedimentation on suspended particles, the interception net blocks large garbage, reduces the impurity load downstream, the water collecting tank guides the relatively clean sewage to the eddy current fan, converts the kinetic energy of water flow into mechanical energy to drive the system, and the high-pressure water is scattered to the inner wall of the box body through the perforated rotating cylinder and the conical water splashing disc, actively peeling off the silt and dirt, breaking through the limitation of traditional reliance on rainfall scouring, continuously cleaning the silt through mechanical force, significantly reducing the siltation rate, and improving the drainage efficiency.

[0021] By setting up the driving support component, it can automatically identify the heavy rain condition and dynamically adjust the drainage structure. When the rainfall increases, the linkage gear device of the water flow impact force and the suction force leading to the urban pipeline at the bottom of the silt removal box is utilized to lift the silt removal screen component and lower the drainage and silt cleaning component. Both are synchronously moved out of the box body, and at the same time, the grate is lifted to form an unobstructed channel, improving the instantaneous water passing capacity. At the same time, the dual anti-blocking mechanism enables the screen to normally intercept debris and clean silt during normal rainfall, and the components are lifted directly for drainage during extreme heavy rain, avoiding the blockage and siltation caused by debris accumulation in traditional grates. After the heavy rain, the externally moved components can be manually removed for cleaning, which not only solves the defect of flow rate limitation but also realizes efficient maintenance.

[0043] As Figures 1 to 12 shown, an embodiment of the present invention provides an automatic cleaning mechanism for silt accumulation in a road sewage outlet, including a silt removal box body 1. A support frame 2 is installed on the top of the silt removal box body 1. An alloy basket cover 3 is hinged at the end of the support frame 2. A cover plate 4 is installed at the front end of the silt removal box body 1. A three-dimensional grid frame 5 is installed at the bottom of the silt removal box body 1. A silt removal screen assembly 6 is sleeved on the top of the silt removal box body 1, and the silt removal screen assembly 6 is used for collecting garbage in the road sewage outlet. A drainage and silt removal assembly 7 is installed inside the silt removal box body 7, and the drainage and silt removal assembly 7 is used for precipitating and transporting the accumulated impurities in the rainstorm water. A driving support assembly 8 is installed on the inner wall of the end of the silt removal box body 1, and the driving support assembly 8 is used for moving the silt removal screen assembly 6 and the drainage and silt removal assembly 7 to outside the upper and lower ends of the silt removal box body 1. The silt removal screen assembly 6 is installed on the top of the drainage and silt removal assembly 7, and the drainage and silt removal assembly 7 is installed at the end of the driving support assembly 8.

[0044] As an implementation manner in this embodiment, as Figures 3 to 7As shown in the figure, the silt removal screen assembly 6 includes a sewage interception screen 61. Block bricks 62 are installed at both ends of the sewage interception screen 61. Elastic clamping blocks 66 are installed at the top of the sewage interception screen 61. A triangular pyramid grid 63 is clamped inside the inner wall of the elastic clamping block 66. Multiple groups of conical nail cylinders 64 are installed at the top of the triangular pyramid grid 63. A handle 65 is installed on the surface of the sewage interception screen 61. The handle 65 is arranged at one end of the triangular pyramid grid 63. Rectangular seats 67 are arranged at the ends of the sewage interception screen 61. A spring frame 68 is installed on one side surface of the rectangular seat 67. There are multiple groups of spring frames 68. A scraper 69 is installed at the end of multiple groups of spring frames 68. A buffer strip 611 is rotatably connected to the end of the rectangular seat 67. A cylinder 612 is installed at the end of the scraper 69. The buffer strip 611 is sleeved on the surface of the cylinder 612. Sliding columns 610 are arranged on both the left and right sides of the block brick 62. When the triangular pyramid grid 63 with conical nail cylinders 64 is installed on the sewage interception screen 61, the elastic clamping blocks 66 at both ends of the sewage interception screen 61 start to come into contact with the ends of the triangular pyramid grid 63. At this time, the elastic clamping blocks 66 are squeezed by the triangular pyramid grid 63 and open to both sides until the elastic clamping blocks 66 come into contact with the surface of the triangular pyramid grid 63, and then the clamping is completed, playing a role in fixing the triangular pyramid grid 63. At this time, the sliding columns 610 at both ends of the block brick 62 are simultaneously slidably connected to the chutes inside the silt removal box body 1. Then, the operator slowly installs the sewage interception screen 61 connected to the triangular pyramid grid 63 into the interior of the silt removal box body 1 by holding the handles 65 at the top of both ends of the sewage interception screen 61, so that the block bricks 62 installed at both ends of the sewage interception screen 61 are respectively sleeved on the plug blocks 84 in the driving support assembly 8. When the sewage interception screen 61 is being installed, the rectangular seats 67 installed at the four ends of the sewage interception screen 61 drive the scrapers 69 installed at the ends of multiple groups of spring frames 68 to scrape the inner wall of the silt removal box body 1. At the same time, when the scraper 69 is pressed, it squeezes multiple groups of spring frames 68 to contract. When multiple groups of spring frames 68 contract, the scraper 69 drives the cylinders 612 installed at both ends to slide inside the buffer strip 611, preventing the scraper 69 from damaging the inner wall of the silt removal box body 1. At the same time, impurities on the inner wall of the silt removal box body 1 are scraped off. When there is precipitation, the silt removal screen assembly 6 starts to operate. Impurities around the sewage outlet flow through the flow of rainwater all the way to the top of the alloy basket cover 3. Then, the conical nail cylinders 64 puncture the pollutants falling on the triangular pyramid grid 63 to prevent entanglement and blockage. Then, the triangular pyramid grid 63 places the fallen leaves, branches and other sundries in a three-dimensional form, reducing the blockage of the water passing gaps. Subsequently, the sewage interception screen 61 re-filters the inflowing sewage.

[0045] As an implementation method in this embodiment, as Figures 4 to 10As shown in the figure, the drainage and dredging component 7 includes a flow driving plate 71, which is installed on the inner surface of the dredging box body 1. A sedimentation tank 72 is arranged below the flow driving plate 71. An interception net 74 is installed at the bottom of the sedimentation tank 72, and there is a spacing between the interception net 74 and the inner wall of the bottom of the sedimentation tank 72. A grid fence 75 is installed on the inner wall of the sedimentation tank 72. A plug-in block 73 is installed at the end of the sedimentation tank 72. A water collecting tank 79 is arranged below the sedimentation tank 72. One end of the water collecting tank 79 is attached to the inner wall of the dredging box body 1. A perforated rotating cylinder 76 is rotatably connected to the bottom of the water collecting tank 79. An eddy current fan 77 is rotatably connected inside the perforated rotating cylinder 76. A conical water splashing plate 78 is arranged at the bottom of the perforated rotating cylinder 76. When the sewage passes through the sewage screening component 6 and then continues to flow into the drainage and dredging component 7, at this time, the inclined flow driving plate 71 starts to convey the sewage, and then the water flow is conveyed into the sedimentation tank 72 installed at one end of the plug-in slot 89 through the plug-in block 73. The flowing sewage continuously enters the sedimentation tank 72 until the sewage overflows the edge of the sedimentation tank 72. Then, the interception net 74 intercepts the sewage sludge and dirt in the sedimentation tank 72 by increasing the contact area with the sludge in the sewage, and at the same time, the grid fence 75 intercepts larger sundries together. At this time, the water flowing out drops into the water collecting tank 79. Through the inclined water collecting tank 79, while increasing the flow rate of the sewage, the sewage enters the perforated rotating cylinder 76 through the bottom of the water collecting tank 79. The flowing sewage impacts the eddy current fan 77. The impacted eddy current fan 77 rotates, and the rotating eddy current fan 77 further accelerates the water flow. When the accelerated water flow is sprayed through the holes of the perforated rotating cylinder 76, the perforated rotating cylinder 76 rotates and sprays under the impact of the water flow. At the same time, the conical water splashing plate 78 at a certain distance from the perforated rotating cylinder 76 receives the water column under high-pressure flow rate and scatters the water flow to the inner wall of the dredging box body 1 for flushing.

[0046] As an implementation method in this embodiment, as Figures 8 to 12As shown, the driving and supporting assembly 8 includes toothed slide rods 81. There are two groups of toothed slide rods 81 arranged oppositely. The two groups of toothed slide rods 81 are slidably connected to the inner chute of the silt removal box body 1. One end of each of the two groups of toothed slide rods 81 is meshed with a gear 82. The gear 82 is rotatably connected to the inner wall of the chute of the silt removal box body 1. One end of the two groups of gears 82 is meshed with a toothed driving rod 83. One end of the two groups of toothed slide rods 81 is provided with a plug-in slot 89. The top of each of the two groups of toothed slide rods 81 is provided with a first spring 85. The top of the first spring 85 is provided with a fixed block 86. The fixed block 86 is installed inside the silt removal box body 1. The top of the toothed driving rod 83 is provided with a plug block 84. The plug block 84 coincides with the building block 62. The bottom of the toothed driving rod 83 is provided with a second spring 87. The bottom of the second spring 87 is provided with a resisting block 88. The resisting block 88 is installed inside the silt removal box body 1. A boosting push plate 810 is installed on the surface of the toothed driving rod 83 on the left side of the three-dimensional grid frame 5. A clamping seat 811 is installed on the surface of the toothed driving rod 83 on the right side of the three-dimensional grid frame 5. When the sewage on the flow driving plate 71 impacts the boosting push plate 810, when the boosting push plate 810 is impacted by the high-speed flowing water, the boosting push plate 810 drives the two toothed slide rods 81 fixedly connected at one end to move downward together. At this time, the downward moving toothed slide rods 81 pull the first spring 85 installed on the top. At this time, the first spring 85 is stretched on the fixed block 86 installed inside the chute of the silt removal box body 1. And when the two toothed slide rods 81 move downward in the chute inside the silt removal box body 1, the gears 82 respectively meshed with the end parts of the two toothed slide rods 81 start to rotate. As the gears 82 rotate, the toothed driving rod 83 meshed with the end parts of the two gears 82 moves. When the toothed driving rod 83 moves, the second spring 87 installed at the bottom of the toothed driving rod 83 is stretched on the resisting block 88. At the same time, the plug block 84 installed at the top of the toothed driving rod 83 pushes the building block 62 to move upward together. At this time, during the process of the toothed slide rods 81 moving downward, the three-dimensional grid frame 5 starts to move away from the bottom of the silt removal box body 1. At the same time, the toothed slide rods 81 installed at the other end of the three-dimensional grid frame 5 move downward together. At the same time, the plug-in slot 89 and the clamping seat 811 drive the sedimentation tank 72 and the water collecting tank 79 to move downward together. At the same time, one end of the sedimentation tank 72 and the water collecting tank 79 close to the inner wall of the silt removal box body 1 scrapes the impurities on the inner wall of the silt removal box body 1. And at this time, the toothed driving rod 83 pushes the sewage intercepting screen 61 to rise out of the inside of the silt removal box body 1 and scrapes the inner wall of the silt removal box body 1 at the same time. Then the sewage screening component 6 and the drainage and silt cleaning component 7 completely move to the outside of the silt removal box body 1. At the same time, the upward movement of the sewage screening component 6 directly pushes open the alloy cover 3, so that the road sewage outlet directly discharges, avoiding the generation of siltation. Until the rainfall decreases, due to the elasticity of the first spring 85 and the second spring 87, the sewage screening component 6 and the drainage and silt cleaning component 7 slowly reset. And when resetting,Clean the inner wall of the desilting box 1 again.

[0047] The working principle of the technical solution provided by the present invention is as follows:

[0048] When using the device, first install the silt removal screen assembly 6 and the drainage silt removal assembly 7 into the interior of the silt removal box 1, then close the cover plate 4, then cover the alloy basket cover 3, and then place the silt removal box 1 into the urban road sewage outlet, and then the support frame 2 is stuck inside the sewage outlet.

[0049] After the desilting box 1 is installed, the desilting screen assembly 6 is first installed inside the desilting box 1, and the triangular pyramid grid frame 63 with the conical nail tube 64 is first installed on the sewage interception screen 61. When the triangular pyramid grid frame 63 is installed on the sewage interception screen 61, the elastic blocks 66 at both ends of the sewage interception screen 61 begin to contact the ends of the triangular pyramid grid frame 63. At this time, the elastic blocks 66 are squeezed by the triangular pyramid grid frame 63 and open to both sides until the elastic blocks 66 are in contact with the surface of the triangular pyramid grid frame 63. The sliding posts 610 at both ends of the block 62 start to slide and connect with the slide grooves in the desilting box 1 at the same time. Then, the operator slowly installs the sewage interception screen 61 connected with the triangular pyramid grid 63 into the desilting box 1 by holding the handles 65 at the tops of the sewage interception screen 61 at both ends, so that the blocks 62 installed at both ends of the sewage interception screen 61 are respectively connected with the plug blocks 84 in the driving support assembly 8. When the sewage interception screen 61 is installed, During the process, the rectangular seats 67 installed at the four ends of the intercepting screen 61 drive the scrapers 69 installed at the ends of the multiple sets of spring frames 68 to scrape the inner wall of the desilting box 1. At the same time, the scrapers 69 are pressed, which squeezes the multiple sets of spring frames 68 to shrink. When the multiple sets of spring frames 68 shrink, the scrapers 69 drive the cylinders 612 installed at both ends to slide inside the buffer strips 611 to prevent the scrapers 69 from damaging the inner wall of the desilting box 1. At the same time, the impurities on the inner wall of the desilting box 1 are scraped off. When it rains, the silt removal screen assembly 6 starts to operate, and the impurities around the sewage outlet flow to the top of the alloy sieve cover 3 through the flow of rainwater, and then the conical nail tube 64 punctures the pollutants that fall onto the triangular pyramid grid 63 to prevent entanglement and blockage, and then the triangular pyramid grid 63 places the fallen leaves, branches and other debris in a three-dimensional form to reduce the obstruction of the water-passing gap, and then the sewage intercepting screen 61 re-filters the inflowing sewage, and then the sewage continues to flow downward to the drainage and silt removal assembly 7.

[0050] After the sewage passes through the silt removal screen assembly 6, it continues to flow into the drainage and silt removal assembly 7. At this time, the inclined flow driving plate 71 starts to convey the sewage, and then the water flow is conveyed to the sedimentation tank 72 installed at one end of the insertion slot 89 through the insertion block 73. The flowing sewage continuously enters the sedimentation tank 72 until the sewage overflows the edge of the sedimentation tank 72. Then, the interception net 74 intercepts the sewage sludge and dirt in the sedimentation tank 72 by increasing the contact area with the sludge in the sewage. At the same time, the grid bar 75 intercepts larger sundries together. At this time, the water flowing out drops into the water collecting tank 79. Through the inclined water collecting tank 79, while increasing the flow rate of the sewage, the sewage enters the perforated rotating cylinder 76 through the bottom of the water collecting tank 79. The flowing sewage impacts the eddy current fan 77. The impacted eddy current fan 77 rotates, and the rotating eddy current fan 77 further accelerates the water flow. When the accelerated water flow is sprayed through the holes of the perforated rotating cylinder 76, the perforated rotating cylinder 76 rotates and sprays under the impact of the water flow. At the same time, the conical water splashing plate 78 at a certain distance from the perforated rotating cylinder 76 is impacted by the water column under high-pressure flow rate, and the water flow is scattered to the inner wall of the silt removal box body 1 for flushing.

[0051] When the rainfall increases to extreme rainstorms, the drive support assembly 8 inside the silt removal box body 1 starts to operate. At this time, the increased rainfall accelerates the water flow speed in the silt removal box body 1, and the impact force becomes larger. The sewage on the flow driving plate 71 impacts the boosting deflector 810. When the boosting deflector 810 is impacted by the high-speed flowing water, the boosting deflector 810 drives the two toothed slide rods 81 fixedly connected to one end to move downward together. At this time, the downward moving toothed slide rods 81 pull the first spring 85 installed at the top. At this time, the first spring 85 is stretched on the fixed block 86 installed inside the chute of the silt removal box body 1. And when the two toothed slide rods 81 move downward in the chute inside the silt removal box body 1, the gears 82 respectively meshed with the end parts of the two toothed slide rods 81 start to rotate. As the gears 82 rotate, the toothed drive rods 83 meshed with the end parts of the two gears 82 move. When the toothed drive rods 83 move, the second spring 87 installed at the bottom of the toothed drive rods 83 is stretched on the blocking block 88. At the same time, the plug block 84 installed at the top of the toothed drive rods 83 pushes the building block 62 to move upward together. At this time, during the downward movement of the toothed slide rods 81, the three-dimensional grid frame 5 starts to move away from the bottom of the silt removal box body 1. At the same time, the toothed slide rods 81 installed at the other end of the three-dimensional grid frame 5 move downward together. At the same time, the insertion slot 89 and the clamping seat 811 drive the sedimentation tank 72 and the water collection tank 79 to move downward together. At the same time, one end of the sedimentation tank 72 and the water collection tank 79 close to the inner wall of the silt removal box body 1 scrapes the impurities on the inner wall of the silt removal box body 1. And at this time, the toothed drive rods 83 push the sewage interception screen 61 to rise out of the inside of the silt removal box body 1, and at the same time scrape the inner wall of the silt removal box body 1. Then the silt removal screen assembly 6 and the drainage and silt cleaning assembly 7 completely move to the outside of the silt removal box body 1. At the same time, the upward movement of the silt removal screen assembly 6 directly pushes open the alloy cover 3, so that the road sewage outlet directly discharges, avoiding the generation of siltation. Until the rainfall decreases, the elastic forces of the first spring 85 and the second spring 87 cause the silt removal screen assembly 6 and the drainage and silt cleaning assembly 7 to slowly reset. And when resetting, the inner wall of the silt removal box body 1 is cleaned again.
