Description

Technical Field

[0001] This utility model relates to the field of road drainage technology, specifically a municipal road drainage structure. Background Technology

[0002] Road drainage includes a pavement drainage section and a roadside drainage section. The pavement drainage section, from bottom to top, consists of a base layer, a waterproof layer, and a permeable layer. A pavement drainage ditch is provided above the waterproof layer. The roadside drainage section includes permeable curb stones located on both sides of the road adjacent to the pavement drainage section, and roadside drainage ditches below the permeable curb stones. The permeable curb stone includes a permeable surface layer and a permeable reinforcement layer. The permeable surface layer contains permeable material, and the permeable reinforcement layer is adjacent to the inner surface of the permeable surface layer. The permeable reinforcement layer has cavities within it. The municipal road drainage structure is a complex and crucial system responsible for removing rainwater, snowmelt, urban wastewater, and groundwater from the road surface and ground, lowering the groundwater level, ensuring normal road use, and extending the road's service life.

[0003] For example, Chinese patent "CN210947091U" discloses a municipal road drainage structure, which proposes: a municipal road drainage structure including a protective plate, a guide hole at the top of the protective plate, a fixed base fixedly connected to the bottom of the protective plate, a threaded post internally threaded to the fixed base, and a connecting post fixedly connected to the bottom of the threaded post. This municipal road drainage structure, through the coordinated arrangement of the protective plate, guide hole, threaded post, fixed base, cleaning hook, fixed frame, support plate, and filter plate, allows accumulated water to enter the sewer through the guide hole when in use. However, before entering the sewer, flocculent matter or larger debris is hooked by the cleaning hook and then filtered by the filter plate, effectively preventing debris from entering the sewer and reducing sewer blockage. Furthermore, because the cleaning hook first passes through primary filtration, it effectively prevents flocculent matter from clogging the filter plate, thereby improving the filtration effect of the filter plate.

[0004] Existing road drainage structures only consider the blockage of sewers by impurities when draining water from roads. However, during continuous rainy seasons and heavy rains, impurities can clog the filter plates above the drainage channels, preventing water from flowing properly into the sewers. This causes water to accumulate on the roads, making it impossible for pedestrians and vehicles to pass. Furthermore, excessive water accumulation can lead to flooding. Utility Model Content

[0005] Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a municipal road drainage structure that can block impurities during periods of non-continuous rainfall, while automatically lowering the filter plate through water pressure to prevent road flooding during emergencies such as heavy rain and continuous downpours. This solves the problem that existing road drainage structures only consider the blockage of sewers by impurities entering them. However, during continuous rainy seasons and heavy rains, impurities can clog the filter plate above the drainage channel, preventing water from flowing properly into the sewers. This leads to water accumulation on the road, making it impossible for pedestrians and vehicles to pass, and excessive water accumulation can cause flooding.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a municipal road drainage structure, including a drainage channel, with drainage pipes connected to both ends of the drainage channel, a plurality of partitions provided on the inner wall of the drainage channel, and a plurality of sliding grooves symmetrically opened on both sides of the inner wall of the drainage channel and on both sides of the partitions, with anti-clogging components provided inside the sliding grooves;

[0008] The anti-blocking component includes a limiting rod, which is fixedly installed inside the slide groove. A support spring is sleeved on the outer wall of the limiting rod. A leakage level plate is movably connected to the upper end of the support spring. Mounting holes are provided at the four corners of the leakage level plate, and the leakage level plate is movably installed on the outer wall of the limiting rod through the mounting holes.

[0009] Preferably, gaps are left between the bottom of several of the partitions and the inner wall of the drainage channel, and the inside of the drainage channel is in a connected state.

[0010] Preferably, both sides of the water-leaking horizontal plate are provided with water-leaking side plates, the gap of the water-leaking side plates is larger than the gap of the water-leaking horizontal plate, and the lower end of the water-leaking side plate is an integral water-leaking hole without a baffle.

[0011] Preferably, a material discharge ramp is provided below the two side leakage side plates. The material discharge ramp is inverted trapezoidal in shape, with all four sides inclined inward. A retrieval component is provided in the material discharge hole at the lower end of the material discharge ramp.

[0012] Preferably, the retrieval assembly includes a receiving box, which is movably disposed inside the material discharge hole below the material discharge ramp. Piston rods are provided at the four corners of the outer wall of the material discharge ramp. The piston rods are movably installed inside the sleeve rod, and the sleeve rod is fixedly connected to the bottom of the drain level plate.

[0013] Preferably, the upper end of the piston rod is provided with a sliding plate, and both sides of the outer wall of the sliding plate are provided with return springs. The outer end of the return spring is fixedly connected with a ball. Two sets of limiting holes are opened on both sides of the outer wall of the sleeve rod. After the ball rises, it is movably installed inside the limiting hole to limit the connection with the material box.

[0014] Preferably, connecting rod bases are provided on both sides above the receiving box, and connecting rods are fixedly connected to the outer walls of the connecting rod bases on both sides. Several spherical floats are provided on the outer walls of the connecting rods.

[0015] Compared with the prior art, this utility model provides a municipal road drainage structure with the following advantages:

[0016] 1. The municipal road drainage structure, by setting up anti-clogging components, will automatically lower the drainage level plate when continuous rainfall causes it to become clogged, due to the water pressure of the accumulated water and the gravity of the impurities. The impurities and water flow into the drainage channel through the drainage side plates on both sides, effectively preventing the generation of road water accumulation when it is impossible to clean the impurities at the drainage outlet in time.

[0017] 2. This municipal road drainage structure, by incorporating a retrieval component, effectively catches impurities flowing from the leaking side plate into the drainage channel along the material drop slope, preventing blockage within the drainage channel. Furthermore, in emergencies such as heavy rain or continuous rainfall, when there are many impurities inside the material drop slope and the water flow cannot normally reach the bottom of the drainage channel, the water accumulates inside the material drop slope. The buoyancy generated by the water flow on the spherical float causes the material drop slope to rise, and the limiting hole prevents the ball bearings from descending, ensuring smooth water flow and preventing excessive water accumulation that could lead to flooding and more severe losses.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 The system includes a drainage channel 1, with drain pipes 11 connected to both ends. The drainage channel 1 is the main drainage channel, with drain pipes 11 connected to both ends for introducing and discharging water. Several baffles 14 are installed on the inner wall of the drainage channel 1, with gaps between the bottom of each baffle 14 and the inner wall of the drainage channel 1, ensuring that the water flow remains connected within the drainage channel 1. Even after passing through the baffles 14, the flow will not be completely blocked. This design may be to increase the flow path of the water within the drainage channel 1, thereby increasing the contact opportunity between the water flow and solid impurities, helping the impurities to settle or disperse. Several grooves 15 are symmetrically opened on both sides of the inner wall of the drainage channel 1 and on both sides of the baffles 14, with anti-clogging components 2 installed inside the grooves 15.

[0029] Both sides of the horizontal drain plate 21 are provided with drain side plates 12. The gaps in the drain side plates 12 are larger than those in the horizontal drain plate 21. The lower end of the drain side plate 12 is a whole drain hole without a baffle. The gaps in the drain side plates 12 are designed to be larger than those in the horizontal drain plate 21. This means that when there are a lot of impurities and garbage, the small gaps on the surface of the horizontal drain plate 21 are blocked. The accumulated rainwater pressure and the weight of the impurities will press the horizontal drain plate 21 down. The accumulated water flow and smaller impurities are discharged into the drainage channel 1 along the drain side plates 12, allowing the water to flow smoothly. The material discharge ramps 13 are provided below the drain side plates 12 on both sides. The material discharge ramps 13 are inverted trapezoidal in shape and all four sides are inclined inward. The material discharge ramps 13 are provided below the drain side plates 12 on both sides. The discharge ramp 13 has an inverted trapezoidal design with all four sides inclined inward. This design helps to concentrate the sedimented or intercepted impurities to the lower end of the discharge ramp 13. A retrieval component 3 is installed in the discharge hole at the lower end of the discharge ramp 13.

[0030] Please see Figures 3-4 The anti-clogging component 2 includes a limiting rod 23, which is fixedly installed inside the slide groove 15. The limiting rod 23 provides a sliding track for the drain level plate 21 and limits its vertical movement. A support spring 24 is sleeved on the outer wall of the limiting rod 23, and the drain level plate 21 is movably connected to the upper end of the support spring 24. Mounting holes 22 are provided at each of the four corners of the drain level plate 21. The drain level plate 21 is movably installed on the outer wall of the limiting rod 23 through the mounting holes 22. The surface of the drain level plate 21 is designed with specific gaps to allow water to flow through while blocking larger impurities. The mounting holes 22 at the four corners of the drain level plate 21 allow the drain level plate 21 to slide up and down within the slide groove 15 via the limiting rod 23. When impurities and water accumulate on the drain level plate 21 to a certain extent, it can automatically descend, allowing water and smaller impurities to flow down the drain side plate 12, preventing blockage of the drain outlet.

[0031] Please see Figures 5-7The retrieval component 3 includes a receiving box 31, which is movably disposed inside the discharge hole below the discharge ramp 13. The main function of the receiving box 31 is to collect impurities that slide down from the discharge ramp 13. Piston rods 35 are provided at the four corners of the outer wall of the discharge ramp 13. The piston rods 35 are movably installed inside the sleeve rod 39, which provides a sliding track for the piston rods 35. The up and down movement of the piston rods 35 can control the position and state of the receiving box 31. The sleeve rod 39 is fixedly connected to the lower part of the drain level plate 21. A sliding plate 36 is provided at the upper end of the piston rod 35. Return springs 37 are provided on both sides of the outer wall of the sliding plate 36. Ball bearings 38 are fixedly connected to the outer ends of the return springs 37. Two sets of limiting holes 310 are opened on both sides of the outer wall of the sleeve rod 39. After the ball bearings 38 rise, they are movably installed inside the limiting holes 310 to limit the receiving box 31. When the piston rod 35 moves upward, the sliding plate 36 also moves upward, compressing the return springs 37 and causing the ball bearings 38 to rise. Two sets of limiting holes 310 are provided on both sides of the outer wall of the sleeve rod 39. When the ball bearing 38 rises to a certain height, it will enter the limiting hole 310 and limit the material box 31 to prevent it from falling. Connecting rod bases 32 are provided on both sides above the material box 31. Connecting rods 33 are fixedly connected to the outer walls of the connecting rod bases 32 on both sides. Several spherical floats 34 are provided on the outer walls of the connecting rods 33. The function of the spherical floats 34 is that when too many impurities accumulate in the material box 31, the water flow cannot flow out from the screen of the material box 31. The water flow accumulates inside the discharge inclined plate 13 and overflows the spherical floats 34. The spherical floats 34 rise due to buoyancy. The force is transmitted to the material box 31 through the connecting rod 33, causing the material box 31 to rise, thereby triggering the rising action of the piston rod 35. The ball bearing 38 enters the limiting hole 310 and limits the material box 31.

[0032] Working Principle: During the rainy season and heavy rain, excessive rainwater carries debris such as garbage and fallen leaves from the green belt and road surface into the drainage channel 1 through the drain plate 21. If the rain lasts too long, the accumulation of debris can block the smaller drainage holes on the surface of the drain plate 21. With the drainage holes blocked, the road surface cannot be cleaned properly during heavy rain, and rainwater accumulates on the road. The water pressure and weight of the debris press the drain plate 21 down, squeezing the support spring 24. Water and smaller debris flow through the larger drainage holes of the drain side plate 12 and down the material discharge inclined plate 13 into the receiving box 31. The debris accumulates inside the receiving box 31, while the water flows through the filter screen of the receiving box 31 into the drainage channel 1 and out through the drain pipe 11. The drain plate 21, freed from pressure, rises and resets due to the elasticity of the support spring 24, continuing to block smaller debris and facilitating its removal. In cases where timely cleaning is impossible during a prolonged rainy season, the receiving box... The receiving box 31 continuously blocks impurities. If the receiving box 31 is filled with impurities, the water cannot flow from the receiving box 31 into the drainage channel 1, and the water accumulates in the discharge ramp 13. The accumulated water provides buoyancy to the spherical float 34, which drives the receiving box 31 to rise. When the receiving box 31 rises, the piston rod 35 drives the sliding plate 36 to rise together inside the sleeve rod 39 until the water can flow out from below the receiving box 31. At this time, the ball bearing 38 returns to its original position due to the elasticity of the return spring 37. When the water rises and passes through the limiting hole 310 on the outer wall of the sleeve rod 39, the ball bearing 38 engages inside the limiting hole 310 to move and limit the material receiving box 31, ensuring that the water flow continues to pass through and preventing accumulation on the road surface. After the rain stops, the staff only needs to lift the drain level plate 21, which will bring out the material receiving box 31 below. After cleaning the impurities on the surface of the drain level plate 21 and inside the material receiving box 31, press the ball bearings 38 on both sides to reset the piston rod 35, and then reinstall the drain level plate 21.
