[0002] Municipal roads will collect a lot of rainwater during rainfall. If the drainage system is blocked, it is easy to cause waterlogging on the road, affecting traffic and road safety. The anti-blocking and silt removal system can promptly clean up the debris and silt in the drainage pipes to ensure that rainwater can be discharged smoothly and avoid waterlogging on the road. For some low-lying areas, an effective drainage system is even more important to prevent the occurrence of waterlogging disasters. Although the system is equipped with preliminary filtering facilities such as the grille of the rainwater collection device, there may still be some smaller debris entering the drainage pipes, such as plastic bags, leaf fragments, pebbles, etc. These debris are easy to accumulate in the pipes and cause blockages.

The output shaft of the forward and reverse waterproof motor 201 is fixedly installed with a threaded rod 202. The threaded rod 202 is rotatably installed on the inner wall of the drainage channel 1 away from the side of the forward and reverse waterproof motor 201. The forward and reverse waterproof motor 201 drives the threaded rod 202 to rotate along the sliding cavity opened on the surface of the drainage channel 1 through the output shaft.

The internal threaded slider 301 is driven by the internal threaded slider 301 to slide under the limit of the sliding cavity through the rotating thread of the threaded rod 202, and the internal threaded slider 301 drives the clamping block 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; The anti-blocking and desilting assembly 3 also includes a positioning clamping frame 309 fixedly installed on one side of the first scraper 304, and a plurality of multifunctional placement tubes 310 are fixedly installed inside the positioning clamping frame 309. The outer sides of the two multifunctional placement tubes 310 located in the center are hinged with two first gear blocks 315, 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 multifunctional placement tube 310, and a hinge rod 317 is hinged on one side of one first gear block 315. The number of hinge rods 317 is fixedly connected to the first gear block 315. There are two of them, one side of the other first gear block 315 is fixedly installed with a long pressure rod 318, another hinge rod 317 is hinged at the middle section of the long pressure rod 318, the end of the long pressure rod 318 away from the first gear block 315 is hinged with a connecting long rod 319, an arc spring is fixedly installed between the connecting long rod 319 and the long pressure rod 318, a corresponding pressure block 320 is fixedly installed at the bottom of the connecting long rod 319, two fixed folding rods 312 are fixedly installed on both sides of the positioning clamping frame 309, one side of the two fixed folding rods 312 is hinged with a round rod 324 through a slot, and the round rod The second scraper 305 is fixedly installed on the outer side of the round rod 324, and a positioning spring is fixedly installed at the connection between the round rod 324 and the second scraper 305. The bottom of the positioning clamping frame 309 is hinged with a limiting pull rod 314, and a spring 311 is fixedly installed between the limiting 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 limiting pull rod 314 and the spring 311 buffer the impact force on the second scraper 305 through the spring elastic force, so as to avoid the second scraper 305 being damaged by excessive pressure. The bottom of the second scraper 305 is fixedly installed with a corresponding spring 323, and the number of scrapers 308 is two. Another scraper 308 is fixedly installed on one side of the corresponding spring 323, and the other scraper 308 is against the upper surface of the filter screen plate 402. An inclined pressure rod 321 is fixedly installed on one side of the second scraper 305. The inclined pressure rod 321 is against the outer side of the corresponding pressure block 320 and is in an inclined state with the second scraper 305 in a normal state, thereby facilitating the shoveling of dirt. The scraper 308 is replaced with a tool with bottom bristles according to the actual cleaning situation, thereby improving the cleaning effect. The same number of second gear blocks 322 are fixedly installed at the bottom of the two hinged rods 317, and the two second gear blocks 322 are arranged in a meshing state. The second gear blocks 322 are hinged on both sides with a horizontal lower pressure plate 313, and a corresponding fixing rod is fixedly installed on one side of the horizontal lower pressure plate 313. A sliding rail is provided on the side of the first scraper 304 facing the horizontal lower pressure plate 313, and the corresponding fixing rod passes through one side of the sliding 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 pressure plate 313, and the bottom of the horizontal lower pressure plate 313 is attached to the top of the filter screen plate 402. The mud and sand carried by rainwater will gradually settle in the sedimentation tank and the pipe to form silt. If the silt is not cleared in time, the silt accumulation will affect the flow and drainage capacity of the drainage system. Some stones and other objects are difficult to discharge. When the garbage that is difficult to push and process is stuck on the filter screen plate 402, the second scraper 305 is blocked by the garbage and deflected along the fixed folding rod 312 through the round rod 324 under the limit of the positioning spring, and the scraper 308 is in contact with the porous slot long plate 401 at the same time. Due to the reaction force of the porous slot long plate 401 and the elastic force of the corresponding spring 323, it starts to Finally, the second scraper 305 is fitted with the porous groove long plate 401, and the second scraper 305 takes the connection point with the fixed folding rod 312 as the center of the circle, and its lower half rotates toward one side of the first scraper 304. The inclined pressure rod 321 is located in its lower half, and 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 connected long rod 319. The long pressure rod 318 causes the other to bend downward through the meshing of the two first gear blocks 315. A first gear block 315 drives the short pressure rod 316 to bend downward, and 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 pressure plate 313 to move downward through the two second gear blocks 322. The horizontal lower pressure plate 313 squeezes the filter screen plate 402 below. At the same time, the horizontal lower pressure plate 313 drives the scraper 308 to move downward synchronously along the slide rail through the corresponding fixed rod, so that the two scrapers 308 are synchronized with the filter screen plate 402. The mesh plate 402 is fitted for cleaning, and the stuck stones and other objects are fully scraped out. According to the degree of clamping between the stones and other garbage and the filter mesh plate 402, the deflection direction of the second scraper 305 increases accordingly, and then the downward movement spacing of the horizontal lower pressure plate 313 also increases, and then the filter mesh plate 402 is pressed and the stone removal force through the hollow airbag horizontal fold block 404 is simultaneously increased, thereby improving the cleaning effect of each small position of the drainage channel, avoiding obstruction of the filter net and affecting the collection of water flow.

[0023] like Figure 8 and Fig. 9As shown, the filter screen assembly 4 includes a filter screen 402 resting against the scraper 308, the number of the filter screens 402 is two, the outer side of the other filter screen 402 is fixedly mounted with a porous slot long plate 401, the porous slot long plate 401 is fixedly mounted at the bottom of the drain 1, a filter screen 402 is slidably mounted on the inner wall of the porous slot long plate 401, and the upper surface of the filter screen 402 under normal conditions is higher than the upper surface of the porous slot long plate 401, and 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 side walls and the bottom of the drainage channel 1, and then push the sludge on the surface out of the filter screen plate 402, remove the sludge and garbage, and avoid affecting the filtration of the filter screen plate 402. The maximum change of 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 slot long plate 401. The two filter screens 402 are provided with a plurality of filter holes 403 in a connected state inside, and a hollow airbag transverse fold block 404 in a hollow state is fixedly installed between the upper and lower filter holes 403. The inner top of the hollow airbag transverse fold block 404 is in a sealed state between the side walls of each hollow airbag transverse fold block 404 when garbage and sludge impact the filter screens 402, and the cavity between the side walls is equivalent to an airbag, thereby buffering the garbage and sludge above, reducing the filter screens 402 from being subjected to excessive impact and shortening their service life. At the same time, when the filter screens 402 located at the top are squeezed, the hollow airbag transverse fold block 404 is The folding block 404 is deformed by squeezing toward the center of the filter hole 403 according to the folding mark, and the stones and other garbage stuck in the upper filter hole 403 are squeezed by the deformed hollow airbag transverse folding block 404 and cooperated with the scraper 308 to be more easily cleaned. At the same time, the deformed hollow airbag transverse folding block 404 forms an outward convex clamping hole, and the radius of this hole is smaller than the radius of the filter hole 403. When the stones and other garbage are scraped out and squeezed by the limit spring 408, they cannot be pressed and stuck deeper in the filter hole 403, and can only be cleaned outward, thereby improving the cleaning effect of the filter hole and preventing the stones and other garbage from being pressed and getting closer to the filter hole when cleaning; An upper deflection rod 407 is hinged on the top of the hollow airbag transverse fold block 404, and a lower deflection rod 406 is hinged on the bottom of the hollow airbag transverse fold block 404. The lower deflection rod 406 and the upper deflection rod 407 are plug-connected, and an expansion ring 405 is hinged at the connection between the upper deflection rod 407 and the lower deflection rod 406. Fixed clamps are provided on the top and bottom of the inner side of the hollow airbag transverse fold block 404, and the fixed clamps are fixedly installed on the upper The bottom of the filter plate 402 and the top of the lower filter plate 402 are respectively hinged with a plurality of lower deflection rods 406 and an upper deflection rod 407 on the fixed snap ring. When the filter plate 402 is compressed, the upper deflection rod 407 deflects along the fixed snap ring. At the same time, the upper deflection rod 407 and the lower deflection rod 406 deflect toward the center of the filter hole 403 in normal state. A limit spring 408 is arranged inside the expansion ring 405. 405 includes a hollow arc tube and an arc-shaped tube, and the hollow arc tube and the arc-shaped tube are slidingly connected, and a limit spring 408 is fixedly installed between the hollow arc tube and the arc-shaped 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 clamp ring, and the lower deflection rod 406 is deflected outward through the lower fixed clamp ring, and the connection between the upper deflection rod 407 and the lower deflection rod 406 moves toward the center of the filter hole 403. Under the limitation of the limit spring 408, the expansion ring 405 shrinks along the hollow arc tube, and the shrunk expansion ring 405 squeezes the hollow airbag transverse fold block 404 to deform toward the center of the filter hole 403, making the deformation of the hollow airbag transverse fold block 404 more stable, and at the same time providing sufficient support force for the hollow airbag transverse fold block 404 to push out stones and other garbage, thereby improving the cleaning effect.

The branch flow conduit 503 passes through the drainage channel 1 and is provided with a suction hole at one end. The sewage pump 502 is used as a driver, and suction is used to use multiple branch flow conduits 503 and the suction holes of the drainage channel 1 as a medium to absorb the sludge and other materials pushed and accumulated in the drainage channel 1 by the anti-blocking and silting component 3, and the sludge and other materials are conducted to the collecting box 501 through the suction holes. The staff cleans the garbage collected in the collecting box 501 by opening the door above the drainage channel 1 that is connected to the collecting box 501.
