Description

Technical Field

[0001] This utility model relates to the field of municipal road storm drain technology, specifically a high-efficiency drainage storm drain for municipal roads. Background Technology

[0002] Existing municipal road storm drains mostly use single-layer drainage pipes, resulting in a single drainage load. During heavy rain, pipe blockages easily lead to road flooding. The built-in filters can only intercept large debris, lacking a tiered filtration design. Small debris and silt easily enter the pipes with the water flow, accumulating over time and reducing drainage efficiency. Therefore, there is an urgent need for a high-efficiency storm drain with dual-pipe drainage, built-in tiered filtration, and easy maintenance to solve the problems of low drainage efficiency, insufficient filtration, and inconvenient maintenance in existing technologies.

Detailed Implementation

[0018] like Figures 1-9 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The projection relationship of this utility model is consistent in the up, down, left, right, front and back directions. It is a high-efficiency drainage rainwater inlet for municipal roads. It includes an outer box 11. The upper and lower ends of the outer box 11 are respectively connected to the upper and lower ends of the outer box 11. An inner box 31 is provided inside the outer box 11. A grid plate 12 that can be flipped open is provided on the top of the outer box 11. A sand filter assembly is provided at the top of the inner box 31. A filter basket assembly is provided in the middle of the inner box 31. The filter basket assembly is located between the upper pipe 13 and the lower pipe 14. An inner cavity 34 is provided inside the inner box 31.

[0019] Advantageously, the top of the outer casing 11 is provided with a rotating groove 21 on the left and right, and a fixed shaft 23 is fixed in the rotating groove 21. Two connecting blocks 24 are fixed on the front side of the grid plate 12. The connecting blocks 24 are provided with snap-fit ​​holes 22, and the snap-fit ​​holes 22 are rotatably connected with the fixed shaft 23.

[0020] Advantageously, the snap-fit ​​hole 22 is inclined at 45° to the rear and upward, so that after the fixed shaft 23 is engaged with the snap-fit ​​hole 22, the grid plate 12 cooperates with the fixed shaft 23 through the connecting block 24 to realize the flipping function. Furthermore, due to the inclined setting of the snap-fit ​​hole 22, the grid plate 12 can only be opened after it has flipped off the top of the outer box 11.

[0021] Advantageously, the top of the outer casing 11 is provided with a top groove 35, and the grating plate 12 is engaged with the top groove 35 so that the grating plate 12 covers the top groove 35.

[0022] Advantageously, the inner cavity 34 is provided with lower connection ports 33 on both sides, which are connected to the lower pipe 14, and the inner cavity 34 is provided with upper connection ports 32 on both sides, which are connected to the upper pipe 13.

[0023] Advantageously, the sand filtering assembly includes an outer frame 44, a bottom frame 41 fixed inside the outer frame 44, a plurality of first storage holes 43 provided on the top of the outer frame 44, and a plurality of second storage holes 42 fixed on the top of the bottom frame 41.

[0024] Advantageously, the outer casing 11 is provided with a groove 36, and the outer frame 44 is snapped into the groove 36.

[0025] Advantageously, the filter basket assembly includes a main body plate 55, a filter chamber 51 is provided inside the main body plate 55, handle grooves 54 are fixed on both sides of the filter chamber 51, a plurality of filter holes 53 are fixed at the bottom of the filter chamber 51, and a plurality of side grooves 56 are provided connecting the front and rear sides of the filter chamber 51.

[0026] Advantageously, the inner box 31 is provided with a snap-fit ​​groove 52, and the main body plate 55 is snapped into the snap-fit ​​groove 52.

[0027] The device consists of multiple units, connected by pipes 61. Pipes 61 connect adjacent upper pipes 13 and lower pipes 14, forming a first drainage pipe and a second drainage pipe. Large debris is intercepted by a grating plate 12. When water flows in from all sides of the device, it first passes through the upper surface of the sand filter assembly, where the sand settles and collects in the first and second storage holes 43 and 42. Then, it passes through the filter holes 53 in the filter basket assembly, where small debris is intercepted. The water is then introduced from the filter holes 53 into the lower side of the inner cavity 34, and then drained by the lower pipes 14 and 61.

[0028] The equipment primarily drains water through the lower pipes 14 and 61, with the water level below the filter basket assembly. When a large amount of water accumulates on the ground and enters the equipment, drainage blockage can easily occur. Furthermore, if there is a lot of debris in the filter basket assembly, the water falls slowly, but the inflow rate exceeds the outflow rate. As a result, the water level in the inner cavity 34 gradually rises, exceeding the filter basket assembly level, and the water is then discharged through the upper pipes 13 and 61. Similarly, when the water flow rate in the external space exceeds the outflow rate through the lower pipes 14 and 61, the water level in the inner cavity 34 is higher, and the water is then discharged into the external space through the upper pipes 13 and 61.

[0029] During specific engineering construction, a foundation pit and pipeline tunnel are first excavated on the ground. Concrete can be poured into the foundation pit and pipeline tunnel. After the concrete hardens, the equipment is installed into the foundation pit. Pipelines 61 are installed to connect the equipment. When multiple equipment are connected, one end of the upper pipeline 13 or lower pipeline 14 of the starting equipment is closed, and the other end is connected to the upper pipeline 61. The upper pipeline 13 and lower pipeline 14 of the ending equipment are respectively connected to a river or lake for drainage. The construction of the foundation pit, pipeline tunnel, and concrete pouring shall be carried out in accordance with the national standards for building construction. Pipeline 61 can be made of PVC or other types of pipe. The structural materials of this equipment, such as the outer casing 11 and the inner casing 31, can also be made of PVC, reinforced concrete, etc., and the selection should be made according to the working conditions.

[0030] When maintaining the equipment, flip the grating plate 12 open to detach it from the top groove 35. The grating plate 12 can be flipped open at a certain angle, or it can be completely removed by disengaging the snap-fit ​​hole 22 from the fixed shaft 23. Remove the bottom side frame 41 and outer side frame 44 upwards from the snap-fit ​​groove 52, and flush out the mud and sand inside the outer side frame 44 and bottom side frame 41. Use the handle groove 54 to lift the filter basket assembly upwards and empty the debris from the filter basket assembly. After cleaning, reinstall the sand filter assembly and filter basket assembly back into the equipment, and then reinstall the grating plate 12.

[0031] After the grille 12 is opened, the inner box 31 can be pulled out or lifted in as a whole using a vehicle-mounted crane, so as to replace or install the inner box 31 as a whole.

[0032] Corrosion-resistant and durable design: Metal parts (grating plate connecting blocks, filter basket assembly) are made of hot-dip galvanized or 304 stainless steel; rubber seals are made of EPDM rubber.

[0033] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
