Description

Technical Field

[0001] The present invention relates to the technical field of road engineering anti-blocking, and particularly relates to an anti-blocking and silt cleaning system for municipal road engineering. Background Art

[0002] During rainfall, a large amount of rainwater will gather on municipal roads. If the drainage system is blocked, it is easy to cause waterlogging on the road surface, affecting traffic and road safety. The anti-blocking and silt cleaning system can timely clean the sundries and silt in the drainage pipeline, ensure the smooth discharge of rainwater, and avoid waterlogging on the road surface. For some areas with low terrain, an effective drainage system is even more crucial to prevent the occurrence of waterlogging disasters. Although there are preliminary filtering facilities such as grilles for rainwater collection devices in the system, some smaller sundries may still enter the drainage pipeline, such as plastic bags, leaf fragments, small stones, etc. These sundries are easy to accumulate in the pipeline and cause blockages.

[0003] In the patent document with the publication number CN112252457B that has been made public, an anti-blocking and silt cleaning system for municipal road engineering is disclosed, belonging to the technical field of municipal road engineering. It includes: a cavity opened inside the sidewalk; a drainage channel opened on the side wall of the sidewalk; and an anti-blocking and silt cleaning device arranged in the cavity and communicated with the drainage channel. A scraper is movably arranged in the drainage channel, and the bottom of the scraper abuts against the bottom wall of the drainage channel. By setting the scraper, some silt in the drainage channel can be scraped and cleaned, effectively loosening the silt, thereby effectively reducing the blockage of the drainage channel. By setting the driving component, the scraper can be effectively driven to drive the scraper to displace along the extension direction of the drainage channel, so that the dirty silt on the inner wall of the drainage channel can be cleaned and scraped off, reducing the blockage of the dirty silt to the drainage channel and effectively preventing and cleaning the blockage of the drainage channel.

[0004] When the above device is in use, the drainage channel is cleaned by the scraper, and a large amount of silt and dirt scraped from the side of the drainage channel will fall to the bottom of the drainage channel. These silts are pumped and cleaned by a sewage pump. Some silts contain stones and other objects that are easy to get stuck in the sewage filter screen at the bottom of the drainage channel, causing these stones to not be completely removed by the sewage pump, and the two scrapers cannot clean the garbage in the card holes well.

[0005] Therefore, this application proposes an anti-blocking and silt cleaning system for municipal road engineering. Summary of the Invention

[0016] Optionally, there are two hinge rods. A long pressing rod is fixedly installed on one side of the other first gear block.

[0017] Optionally, two fixed folding rods are fixedly installed on both sides of the positioning clamping frame. One side of the two fixed folding rods is hinged with a round rod through a slot.

The flow distribution conduit passes through one end of the drainage channel and is provided with a suction hole.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. The side walls of each hollow airbag folding block are in a sealed state. The cavity between the side walls is equivalent to an airbag, which can buffer the garbage and sludge above, reducing the excessive impact on the filter mesh plate and shortening its service life. At the same time, the deformed hollow airbag folding block forms an outward convex clamping hole, and the radius of this hole is smaller than that of the filter hole. When stones and other garbage are scraped and extruded by the limiting spring, they cannot be pressed and stuck deeper in the filter hole, but can only be cleaned outward, thus improving the cleaning effect of the filter hole and avoiding the stones and other garbage being pressed and stuck tighter and tighter with the filter hole during cleaning.

[0023] 2. Under the limitation of the limiting spring, the expansion ring causes the arc-shaped tube to contract along the hollow arc tube. The contracted expansion ring squeezes the hollow airbag folding block to deform towards the center of the filter hole, making the deformation of the hollow airbag folding block more stable. At the same time, it provides sufficient supporting force for the hollow airbag folding block to push out stones and other garbage, thus improving the cleaning effect.

[0024] 3. The horizontal lower pressing plate drives the scraper to move downward synchronously along the slide rail through the corresponding fixing rod, causing the two scrapers to synchronously fit with the filter mesh plate for cleaning, scraping out the stuck stones and other objects sufficiently. According to the clamping degree between the stones and other garbage and the filter mesh plate, the deflection direction of the second scraper increases accordingly, and then the downward movement distance of the horizontal lower pressing plate also increases. Consequently, the force exerted by the filter mesh plate through the hollow airbag folding block to expel the stones increases synchronously, thereby improving the cleaning effect on each small position of the drainage channel and preventing the filter mesh from being blocked and affecting the water flow collection.

Detailed implementation manners

[0036] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] As Figure 1 shown, a municipal road engineering anti-blocking and dredging system proposed by the present invention includes a drainage channel 1. Symmetrically arranged transmission drive assemblies 2 are fixedly installed on both sides of the drainage channel 1. An anti-blocking and dredging component 3 is installed on both sides of the drainage channel 1 through the transmission drive assembly 2. A filter screen plate assembly 4 is arranged at the bottom of the drainage channel 1. A sewage cleaning component 5 is installed on both sides of the drainage channel 1 through a cavity. Sewage first flows into the drainage channel 1. The sewage first flows through the filter screen plate assembly 4 into the flow cavity at the bottom of the drainage channel 1, while the sludge and garbage are separated above the filter screen plate assembly 4. At the same time, the sludge is collected and separated by the sewage cleaning component 5;

[0038] The transmission drive assembly 2 includes a forward and reverse waterproof motor 201 fixedly installed on both sides of the drainage channel 1. A threaded rod 202 is fixedly installed on the output shaft of the forward and reverse waterproof motor 201. The side of the threaded rod 202 away from the forward and reverse waterproof motor 201 is rotatably installed on the inner wall of the drainage channel 1. The forward and reverse waterproof motor 201 drives the threaded rod 202 to rotate along the sliding cavity formed on the surface of the drainage channel 1 through the output shaft.

[0039] As Figures 2 - 7 shown, the anti-blocking and dredging assembly 3 includes an internally threaded slider 301 threadedly connected to the outside of the threaded rod 202. A guide rod 302 and an auxiliary guide rod 303 are fixedly installed on one side of the internally threaded slider 301. A first scraper 304 is fixedly installed on the outside of the guide rod 302 and the auxiliary guide rod 303 through two clamping blocks 306. A scraper 308 is slidably installed inside the first scraper 304. The internally threaded slider 301 is driven by the rotation of the threaded rod 202 to slide under the limit of the sliding cavity. The internally threaded slider 301 drives the clamping blocks 306 and the first scraper 304 to slide along the inside of the drainage channel 1 through the guide rod 302 and the auxiliary guide rod 303;

[0040] The anti-blocking and dredging component 3 further includes a positioning and clamping frame 309 fixedly installed on one side of the first scraper 304. A plurality of multi-functional placement pipes 310 are fixedly installed inside the positioning and clamping frame 309. Two first gear blocks 315 are hinged on the outer sides of the two multi-functional placement pipes 310 located in the center, and the two first gear blocks 315 are arranged in a meshing state. A restoring spring is fixedly installed at the connection between the two first gear blocks 315 and the multi-functional placement pipe 310. A hinge rod 317 is hinged on one side of one first gear block 315, and the number of hinge rods 317 is two. A long pressure rod 318 is fixedly installed on one side of the other first gear block 315. The other hinge rod 317 is hinged in the middle of the long pressure rod 318. An arc spring is fixedly installed between the connection long rod 319 and the long pressure rod 318. A corresponding pressing block 320 is fixedly installed at the bottom of the connection long rod 319. Two fixed folding rods 312 are fixedly installed on both sides of the positioning and clamping frame 309. A round rod 324 is hinged on one side of the two fixed folding rods 312 through a slot. A second scraper 305 is fixedly installed on the outer side of the round rod 324. A positioning spring is fixedly installed at the connection between the round rod 324 and the second scraper 305. A limit pull rod 314 is hinged at the bottom of the positioning and clamping frame 309. A spring 311 is fixedly installed between the limit pull rod 314 and the second scraper 305. When the second scraper 305 rotates along the fixed folding rod 312 through the round rod 324, the limit pull rod 314 and the spring 311 buffer the impact force received by the second scraper 305 through the spring elasticity, avoiding damage to the second scraper 305 due to excessive pressure. A corresponding spring 323 is fixedly installed at the bottom of the second scraper 305. The number of scrapers 308 is two. The other scraper 308 is fixedly installed on one side of the corresponding spring 323. The other scraper 308 abuts against the upper surface of the filter mesh plate 402. An inclined pressure rod 321 is fixedly installed on one side of the second scraper 305. The inclined pressure rod 321 abuts against the outer side of the corresponding pressing block 320, and is in an inclined state when the second scraper 305 is in its normal state, thus facilitating the shoveling of dirt. The scraper 308 is replaced with a tool with bottom bristles according to the actual situation of cleaning, thereby improving the cleaning effect;

[0041] The bottoms of two hinge rods 317 are fixedly installed with the same number of second round tooth blocks 322, and the two second round tooth blocks 322 are arranged in a meshing state. The two sides of the second round tooth block 322 are hinged with a horizontal lower pressing plate 313. One side of the horizontal lower pressing plate 313 is fixedly installed with a corresponding fixed rod. A slide rail is provided on the side of the first scraper 304 facing the horizontal lower pressing plate 313. The corresponding fixed rod passes through one side of the slide rail and is fixedly installed on the outside of a scraper 308. The bottom of the scraper 308 is flush with the bottom of the horizontal lower pressing plate 313. The bottom of the horizontal lower pressing plate 313 is attached above the filter screen plate 402. The sediment carried by the rainwater will gradually precipitate in the grit chamber and the pipeline, forming silt. If the silt cleaning is not timely, the accumulation of silt will affect the flow rate and drainage capacity of the drainage system. Some stones and other objects are difficult to discharge. When the filter screen plate 402 is stuck with garbage that is difficult to push and process, the second scraper 305 deflects along the fixed folding rod 312 under the limit of the positioning spring due to the obstruction of this garbage. At the same time, the scraper 308 contacts the porous groove long plate 401. Due to the reaction force of the porous groove long plate 401 and the elastic force of the corresponding spring 323, it always fits with the porous groove long plate 401. The second scraper 305 rotates with the connection point with the fixed folding rod 312 as the center, and the lower half of it moves towards the side of the first scraper 304. The inclined pressure rod 321 is located in its lower half. The inclined pressure rod 321 squeezes the corresponding pressure block 320. The corresponding pressure block 320 drives the long pressure rod 318 to bend downward under the limit of the arc spring through the connecting long rod 319. The long pressure rod 318 causes the other first round tooth block 315 to drive the short pressure rod 316 to bend downward through the meshing of the two first round tooth blocks 315. The short pressure rod 316 and the long pressure rod 318 drive the two hinge rods 317 to move downward. The hinge rod 317 drives the horizontal lower pressing plate 313 to move downward through the two second round tooth blocks 322. The horizontal lower pressing plate 313 squeezes the filter screen plate 402 below. At the same time, the horizontal lower pressing plate 313 drives the scraper 308 to move downward synchronously along the slide rail through the corresponding fixed rod, causing the two scrapers 308 to fit with the filter screen plate 402 synchronously for cleaning, fully scraping out the stuck stones and other objects. According to the clamping degree between the stones and other garbage and the filter screen plate 402, the deflection direction of the second scraper 305 increases accordingly. Furthermore, the downward movement distance of the horizontal lower pressing plate 313 also increases. Furthermore, the pressure exerted by the filter screen plate 402 on the stones through the hollow airbag folding block 404 increases synchronously, thereby improving the cleaning effect on each small position of the drainage channel and avoiding the blockage of the filter screen, which affects the collection of water flow.

[0042] Such as Figure 8 And Figure 9As shown in the figure, the filter screen plate assembly 4 includes a filter screen plate 402 that abuts against the lower part of the scraper 308. The number of filter screen plates 402 is two. A porous groove long plate 401 is fixedly installed on the outer side of the other filter screen plate 402. The porous groove long plate 401 is fixedly installed at the bottom of the drainage channel 1. One filter screen plate 402 is slidably installed on the inner wall of the porous groove long plate 401, and the upper surface of one filter screen plate 402 is higher than the upper surface of the porous groove long plate 401 under normal conditions. The corresponding sliding cavity 307 drives the scraper 308 to contact the filter screen plate 402. The filter screen plate 402 is not squeezed under normal conditions. Then, the corresponding sliding cavity 307 and the scraper 308 contact the two side walls and the bottom of the drainage channel 1 to push the sludge on its surface out of the filter screen plate 402, removing the sludge and garbage to avoid affecting the filtration of the filter screen plate 402. The maximum change in the pressure on the filter screen plate 402 is that the upper surface of the filter screen plate 402 is flush with the upper surface of the porous groove long plate 401;

[0043] A plurality of filter holes 403 are provided in the two filter screen plates 402 in a communicating state. A hollow airbag horizontal folding block 404 in a hollow state is fixedly installed between the upper and lower filter holes 403. When the garbage and sludge impact the filter screen plate 402, the side walls of each hollow airbag horizontal folding block 404 are in a sealed state, and the cavity between the side walls is equivalent to an airbag, thereby buffering the garbage and sludge above, reducing the excessive impact on the filter screen plate 402 and shortening its service life. At the same time, when the upper filter screen plate 402 is squeezed, the hollow airbag horizontal folding block 404 is squeezed and deformed towards the center of the filter hole 403 according to the crease. Then, the garbage such as stones stuck in the upper filter hole 403 is more easily cleaned by the deformed hollow airbag horizontal folding block 404 in cooperation with the scraper 308. At the same time, the deformed hollow airbag horizontal folding block 404 forms an outwardly convex clamping hole, and the radius of this hole is smaller than the radius of the filter hole 403. This causes the garbage such as stones to be scraped out by the limiting spring 408 when being squeezed and cannot be stuck deeper in the filter hole 403 under pressure, but can only be cleaned outwards, thereby improving the cleaning effect of the filter hole and avoiding the garbage such as stones being pressed tighter and tighter with the filter hole during cleaning;

[0044] Above the hollow airbag folding block 404, there is an upper deflection rod 407 hinged. Below the hollow airbag folding block 404, there is a lower deflection rod 406 hinged. The lower deflection rod 406 and the upper deflection rod 407 are arranged in a plug-in manner. At the connection of the upper deflection rod 407 and the lower deflection rod 406, there is an expansion ring 405 hinged. On the inner top and bottom of the hollow airbag folding block 404, there are fixed clamping rings respectively. The fixed clamping rings are fixedly installed at the bottom of the upper filter screen plate 402 and the top of the lower filter screen plate 402. On the fixed clamping rings, there are respectively hinged multiple lower deflection rods 406 and upper deflection rods 407. When the filter screen plate 402 is pressed, the upper deflection rod 407 deflects along the fixed clamping ring. At the same time, the upper deflection rod 407 and the lower deflection rod 406 deflect towards the center of the filter hole 403 in the normal state. Inside the expansion ring 405, there is a limiting spring 408. The expansion ring 405 includes a hollow arc tube and an arc tube, and the hollow arc tube and the arc tube are arranged in a sliding connection. The limiting spring 408 is fixedly installed between the hollow arc tube and the arc tube. When the upper filter screen plate 402 is squeezed, the filter screen plate 402 drives the upper deflection rod 407 to deflect along the upper fixed clamping ring, and the lower deflection rod 406 deflects outwards through the lower fixed clamping ring. The connection of the upper deflection rod 407 and the lower deflection rod 406 moves towards the center of the filter hole 403. Under the limitation of the limiting spring 408, the arc tube of the expansion ring 405 contracts along the hollow arc tube. The contracted expansion ring 405 squeezes the hollow airbag folding block 404 to deform towards the center of the filter hole 403, making the deformation of the hollow airbag folding block 404 more stable. At the same time, it provides sufficient supporting force for the hollow airbag folding block 404 to push out stones and other garbage, thereby improving the cleaning effect.

[0045] As Figure 10 , the sewage cleaning component 5 includes a collection box 501 fixedly installed on the inner wall of the cavity of the drainage channel 1. One side of the collection box 501 is fixedly installed with a sewage pump 502 through a circulation pipe. The output end of the sewage pump 502 is fixedly installed with a flow distribution conduit 503. The flow distribution conduit 503 is provided with a suction hole at one end passing through the drainage channel 1. Driven by the sewage pump 502, using the suction force and taking multiple flow distribution conduits 503 and the suction holes of the drainage channel 1 as a medium, the sludge and other substances piled up by the anti-blocking and dredging component 3 in the drainage channel 1 are sucked, and these sludge and other substances are conducted to the collection box 501 through the suction holes. And the staff cleans the garbage collected in the collection box 501 by opening the hatch connected to the collection box 501 above the drainage channel 1.
