Description

Technical Field

[0001] The present invention relates to the technical field of road water supply and drainage, and particularly relates to a road water supply and drainage device capable of alleviating road waterlogging. Background Art

[0002] In the process of road design, in order to ensure that rainwater on the road can be drained in time on rainy days, the middle of the road is generally higher than both sides of the road, and drainage wells are arranged at intervals on the ground near the road shoulders on both sides of the road. In order to ensure the flatness of the road surface, a rain grate is arranged at the opening of the drainage well on the road surface.

[0003] Referring to the Chinese invention patent with the publication number: CN118273431B and the name: A road water supply and drainage system capable of alleviating road waterlogging, through the arranged rain grate and motor 1, first, the rain grate can preliminarily filter some large-particle impurities in the rainwater, which can avoid excessive accumulation of impurities in the sewer. Then, control motor 1 to start. When motor 1 starts, it can drive the plate-shaped blade to fully crush the large-particle impurities collected in the filter cylinder. By crushing the impurities, the flow rate of rainwater can be accelerated, thereby effectively alleviating the waterlogging on the road. Among them, the rotation of the lower rotating rod can also drive the diversion plate to rotate, and when the diversion plate rotates, it can quickly transmit the falling rainwater into the water conveyance channel, thereby accelerating the rate of waterlogging diversion again, greatly improving the working efficiency of the drainage system.

[0004] However, in the actual use process, there are still some problems in the above technical solution:

[0005] 1. During the process of filtering treatment using the grate, garbage and other sundries will accumulate in the upper area of the grate. As these accumulations reach a certain volume density, it will have a negative impact on the efficiency of the drainage system, resulting in a decrease in the drainage rate. And relying only on the simple mechanical operation of the cleaning brush, it is difficult to completely remove these accumulations, and they are likely to re-accumulate when the water flows out, thus continuously affecting the drainage performance.

[0006] 2. In the case of waterlogging, the water level often exceeds the installation height of the grate. The lack of an effective warning mechanism makes it difficult for maintenance personnel to quickly locate the specific position of the drainage grate. In addition, when vehicles and pedestrians pass and step on or roll over the grate, especially when a heavy vehicle passes, it will exert a greater pressure on the grate structure, increasing the risk of damage to the grate, which not only affects the normal operation of the drainage facilities but also shortens the service life of the grate.

[0007] 3. For filamentous waste, such as hair, slender ribbons, etc., they are easy to entangle and hang on the grid structure of the grate. The removal of such sundries usually requires manual intervention, which is not only cumbersome but also inefficient, increasing the maintenance cost and difficulty. Summary of the Invention

[0022] Compared with the prior art, the present invention provides a road water supply and drainage device that can relieve road waterlogging, and has the following beneficial effects:

[0023] 1. For the road water supply and drainage device that can relieve road waterlogging, the control motor operates, driving two filter bars on the same pair of rotating shafts to rotate in opposite directions, so that the garbage and other sundries on the filter bars are flipped into the interior of the fixed frame. Since some garbage and other sundries are easily hung and stuck on the filter bars, when the filter bars rotate, the sliding columns at the lower ends of the filter bars will slide inside the guide grooves, driving the push bars to slide outwards, thus pushing off the hung and stuck garbage and other sundries, facilitating the cleaning of garbage and other sundries and being conducive to the drainage of waterlogging.

[0024] 2. For the road water supply and drainage device that can relieve road waterlogging, the rotation of the rotating shaft drives the cam to rotate, continuously pressing the first piston rod. The gas inside the air compression cylinder pushes the second piston rod to rise through the air pipe, causing the reflector plate to rise, warning pedestrians and vehicles, avoiding trampling and rolling, thus extending the service life. The gas releases pressure through the pressure relief valve on it. When the waterlogging is completely drained, the solenoid valve can be controlled to open, releasing the gas inside the air pipe. The third spring contracts, and the second piston rod and the reflector plate descend, facilitating re-operation.

[0025] 3. For the road water supply and drainage device that can relieve road waterlogging, the garbage and other sundries brought in by the flipping of the filter bars will fall onto the filter plate. The electric push rod is controlled to operate, and the extrusion block pushes the garbage and other sundries on the filter plate to slide above the storage filter frame and squeezes them to make them more compact, reducing the occupied space and facilitating the falling of the garbage and other sundries into the interior of the storage filter frame, thus facilitating the cleaning of the garbage and other sundries. When the extrusion block moves, the drainage holes are dredged through the comb plate. When there are filaments such as hair hanging on the filter plate, when the extrusion block moves, the scraping block can well hold the filaments such as hair, thus facilitating pulling them away from the filter plate and pushing them into the interior of the storage filter frame. When the storage filter frame needs to be cleaned, the filter bars are driven to rotate vertically, and then one can reach out and grab the storage filter frame and pull it out for cleaning, with convenient operation.

[0048] Embodiment 2:

[0049] Based on Embodiment 1, with reference to Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , a road water supply and drainage device capable of alleviating road waterlogging, a warning mechanism 3 is connected to the fixed frame 1. The warning mechanism 3 includes a fixed cylinder 34. Fixed cylinders 34 are installed at both ends of the fixed frame 1. A second piston rod 35 is slidably connected to the fixed cylinder 34. A third spring 37 is installed between the second piston rod 35 and the fixed cylinder 34. The top end of the second piston rod 35 extends out of the fixed frame 1 and is fixedly connected to a reflector 31. A cam 39 is fixedly connected to the rotating shaft 22. An air pipe 32 communicating with the inside is installed on the fixed cylinder 34. An air pumping assembly 33 is connected to the fixed frame 1.

[0051] In the present invention, a pressure relief valve 38 is installed on the air pipe 32. The air pipe 32 communicates with the outside through the pressure relief valve 38. Thus, when the rotating shaft 22 rotates, the force provided by its rotation is used to continuously pump air into the air pipe 32 to provide air pressure.

[0052] Embodiment 3:

[0053] Based on Embodiment 2, with reference to Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16, a road drainage device that can relieve road waterlogging. A cleaning mechanism 4 is connected to the fixed frame 1. The cleaning mechanism 4 includes a filter plate 41. A pair of filter plates 41 are installed at the bottom of the fixed frame 1 where it is located at the bottom of the filter strip 21. The filter plate 41 is provided with strip-shaped drainage holes 46. A storage filter frame 44 is inserted below the middle of the pair of filter plates 41. A pressing block 48 is slidably connected to the filter plate 41. A comb plate 43 is installed at the bottom end of the pressing block 48. The comb plate 43 is slidably connected to the filter plate 41 through the drainage holes 46. An electric push rod 42 is rotatably connected between the comb plate 43 and the fixed frame 1. The electric push rod 42 is electrically connected to the power supply control component 28. A scraping block 49 that slidably abuts against the filter plate 41 is provided on the pressing block 48, so as to facilitate the cleaning of the flipped-down garbage.

[0054] In the present invention, the drainage holes 46 are perpendicular to the side wall of the storage filter frame 44. One end of the filter plate 41 close to the storage filter frame 44 has an arc-shaped structure, so as to facilitate the dredging of the drainage holes 46, and at the same time, the blocked garbage and other sundries can be pushed into the interior of the storage filter frame 44.

[0055] In the present invention, the width of the storage filter frame 44 is smaller than the distance between a pair of rotating shafts 22, and the bottom end of the storage filter frame 44 extends out of the bottom of the filter plate 41, so as to facilitate the extraction and cleaning of the storage filter frame 44.

[0056] In the present invention, the scraping block 49 is slidably connected to the pressing block 48, and a fourth spring 5 is installed between the scraping block 49 and the pressing block 48, so that the scraping block 49 can tightly abut against the filter plate 41, facilitating the scraping of hair and other filaments.

[0057] In the present invention, a scraping groove 47 is provided on the filter plate 41. The scraping groove 47 has a frustum-shaped structure. The scraping block 49 extends into the interior of the scraping groove 47 through the fourth spring 5 and slidably abuts against the filter plate 41, so as to facilitate the lifting of hair and other filaments.

[0058] In the present invention, a shielding component 45 is connected to the fixed frame 1. The shielding component 45 includes a fixed rod 452. The fixed frame 1 is provided with a fixed rod 452 at one end of the pressing block 48 facing away from the storage filter frame 44. A rotating cylinder 453 is rotatably connected to the fixed rod 452. A volute spring 454 is installed between the rotating cylinder 453 and the fixed rod 452. A waterproof cloth 451 is wound around the outer wall of the rotating cylinder 453. The free end of the waterproof cloth 451 is fixedly connected to the pressing block 48, so as to prevent garbage and other sundries from entering the interior of the pressing block 48 and avoid the need for later cleaning.

[0059] In the present invention, a pulley 455 is rotatably connected to one side of the fixed frame 1 close to the top of the pressing block 48. The waterproof cloth 451 rolls and abuts against the top end of the pulley 455, so that the top end of the waterproof cloth 451 can be close to the fixed frame 1 to block garbage and other sundries from entering.

[0060] Working principle: Insert the fixed frame 1 onto the sewer manhole on the roadside. When it rains, garbage and other sundries on the road surface often flow with the water to above the filter strip 21 of the fixed frame 1, the drainage speed will slow down, and the road will accumulate water. At this time, by setting the power supply control component 28, the power supply control component 28 has a built-in power supply and a control module, which can control the motor 241 to work on rainy days. When the motor 241 works, it drives the drive rod 242 to work, thereby driving the worm 243 to drive the worm gear 244 to rotate, making the rotating shaft 22 rotate. The same pair of rotating shafts 22 rotate in opposite directions to each other, thereby driving the two filter strips 21 on the same pair of rotating shafts 22 to rotate in opposite directions to each other, so that the garbage and other sundries on the filter strip 21 are flipped to the inside of the fixed frame 1. Since some garbage and other sundries are easily hung and stuck on the filter strip 21, when the filter strip 21 rotates, the sliding column 25 at the lower end of the filter strip 21 will slide inside the guide groove 23, thereby driving the push bar 26 to slide outwards, so as to push down the hung and stuck garbage and other sundries. The first spring 27 will be stretched. When the filter strip 21 rotates to the horizontal position, the first spring 27 contracts, thereby driving the push bar 26 to tightly contact the filter strip 21, preventing the push bar 26 from falling off after the sliding column 25 is separated from the guide groove 23, so as to ensure the continuous operation of the push bar 26, thus facilitating the cleaning of garbage and other sundries and promoting the drainage of accumulated water;

[0061] When there is accumulated water, the solenoid valve 36 is closed. The rotation of the rotating shaft 22 will drive the cam 39 to rotate, thereby continuously pressing the first piston rod 332. The second spring 335 is continuously compressed and elongated. The gas inside the air compression cylinder 331 is compressed by the first piston rod 332 and passes through the second one-way valve 334 into the inside of the air pipe 32. When the first piston rod 332 rises, the external gas enters the air compression cylinder 331 through the first one-way valve 333. The gas inside the air pipe 32 enters the inside of the fixed cylinder 34, thereby pushing the second piston rod 35 to rise, so that the reflector 31 rises, warning passers-by and vehicles to avoid trampling and rolling. The third spring 37 is stretched. The length of the second piston rod 35 is limited. When the air pressure inside the fixed cylinder 34 reaches a certain value, the gas releases pressure through the pressure relief valve 38 on the air pipe 32. When the accumulated water is completely drained, the solenoid valve 36 can be controlled to open, thereby releasing the gas inside the air pipe 32. The third spring 37 contracts, and the second piston rod 35 and the reflector 31 descend, facilitating re-operation;

[0062] The garbage and other sundries brought in by the flipping of the filter strip 21 will fall onto the filter plate 41. The drain holes 46 are strip-shaped and relatively thin, so that water can be filtered out. Control the operation of the electric push rod 42. The electric push rod 42 extends, pushing the extrusion block 48 to slide. The extrusion block 48 pushes the garbage and other sundries on the filter plate 41 to slide above the storage filter frame 44 and performs extrusion to make it more compact, reducing the occupied space and facilitating the falling of the garbage and other sundries into the interior of the storage filter frame 44, thereby facilitating the cleaning of the garbage and other sundries. When the extrusion block 48 slides, it pulls the waterproof cloth 451 to extend, the pulley 455 rotates, the rotating cylinder 453 rotates and releases, and the scroll spring 454 is compressed, thus effectively preventing the garbage and other sundries from falling inside the extrusion block 48. When the extrusion block 48 retracts, the waterproof cloth 451 automatically winds up. When the extrusion block 48 moves, the drain holes 46 are dredged through the comb plate 43. When there are filamentous substances such as hair hanging on the filter plate 41, when the extrusion block 48 moves, the fourth spring 5 pushes the scraping block 49 into the scraping groove 47, and a gap will be formed between the hair and other filamentous substances and the scraping groove 47. The scraping block 49 can well hold the hair and other filamentous substances, thus facilitating pulling them away from the filter plate 41 and pushing them into the interior of the storage filter frame 44. When it is necessary to clean the storage filter frame 44, drive the filter strip 21 to rotate to the vertical position, then you can reach out and grab the storage filter frame 44 and pull it out for cleaning, which is convenient to operate.

[0063] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
