Description

Technical Field

[0001] The utility model relates to the technical field of road rainwater discharge, and more particularly to a road rainwater discharge structure. Background Art

[0002] With the rapid development of urbanization, more and more municipal roads are being built, which has greatly improved people's living, residence and travel conditions. However, during heavy rainfall, rainwater carries a large amount of debris such as leaves and is discharged into underground drainage pipes, which can easily cause blockage of underground drainage pipes, seriously affecting the normal drainage on the road, resulting in more serious water accumulation problems on the road, and even causing floods in severe cases. It poses a great safety hazard to pedestrians and vehicles, seriously affecting traffic and bringing great inconvenience to people's lives. Therefore, the rainwater drainage structure on the road is an indispensable part of road construction.

[0003] The utility model patent with application number 202223240505.4 discloses a municipal road rainwater drainage structure, including a ground, a rainwater drainage trough is opened on the top of the ground, the bottom of the rainwater drainage trough is connected to a water pipe, a manhole cover is set on the top of the ground, the manhole cover is located at the top of the rainwater drainage trough, and the top of the manhole cover is opened with evenly distributed through grooves. An installation frame is set inside the rainwater drainage trough, a filter screen is fixedly installed on the inner side of the installation frame, and a folding plastic plate is set on the top of the installation frame.

[0004] Through the above technical solution, although the foldable plastic plate can be unfolded upward so that the impurities on the top of the filter are surrounded by the foldable plastic plate, the impurities are prevented from falling into the inside of the rainwater discharge trough when the filter is replaced, thereby achieving the purpose of effectively removing and cleaning the impurities, preventing the fallen impurities from clogging the water pipe and avoiding a great impact on rainwater discharge. At the same time, it solves the problem that the filter needs to be replaced when the device discharges rainwater, and when the filter is replaced, the impurities on the top of the filter are easily dropped into the inside of the drainage trough, causing the drainage trough to be easily blocked.

[0005] However, there is no structure in the rainwater discharge trough to collect impurities such as leaves filtered on the filter. If too many leaves and other debris carried by rainwater accumulate on the filter, the filter holes will be blocked, reducing the drainage effect of the filter, causing rainwater to accumulate continuously in the rainwater discharge trough and eventually spread to the road, causing the road water level to continue to rise. In order to prevent the filter from being blocked and affecting drainage, cleaners need to frequently take out the filter to clean it, which increases the cleaning burden of cleaners and has low practicality.

DETAILED DESCRIPTION

[0018] Reference Figures 1 to 3 The embodiments of the present invention are further described.

[0019] A road rainwater drainage structure includes a road surface 1, a drainage trough 2 connected to an underground drainage pipe is opened on the road surface 1, a manhole cover 3 flush with the road surface 1 is installed on the drainage trough 2, and a leakage hole 03 is opened on the manhole cover 3, a collection box 4 and a dust collecting frame 5 are provided in the drainage trough 2, the dust collecting frame 5 is placed below the collection box 4 and installed on the collection box 4, a filter screen 6 is hinged on the collection box 4, and a filter plate 7 is hinged on the dust collecting frame 5, the filter screen 6 and the filter plate 7 are both movable on the side wall of the drainage trough 2 and are both detachably connected to the side wall of the drainage trough 2, the filter screen 6 is inclined toward the collection box 4, and the filter plate 7 is inclined toward the dust collecting frame 5, a plurality of drain holes 04 are opened on the collection box 4, and a plurality of water outlet holes 05 are opened on the dust collecting frame 5.

[0020] Working principle: Rainwater enters the filter screen 6 of the drainage trough 2 through the leakage hole 03 on the manhole cover 3. The filter screen 6 initially intercepts and filters the leaves and other impurities in the rainwater. The filter plate 7 cooperates with the filter screen 6 to further intercept and filter the rainwater filtered by the filter screen 6, better preventing the leaves and other impurities in the rainwater from entering the underground drainage pipe and causing blockage and affecting the drainage efficiency.

[0021] The filter screen 6 is tilted toward the collection box 4 to facilitate the filter screen 6 to filter out accumulated leaves and impurities and fall into the collection box 4 for collection, thereby preventing the leaves and impurities on the filter screen 6 from accumulating too much and clogging the filter holes of the filter screen 6, causing rainwater to accumulate in the drainage trough 2 and spread onto the road surface 1, causing water accumulation on the road surface 1. The drainage holes 04 on the collection box 4 are used to allow the rainwater entering the collection box 4 to flow out into the drainage trough 2 without accumulating in the collection box 4, thereby avoiding affecting the discharge of rainwater into the underground drainage pipe and improving the drainage effect.

[0022] The filter plate 7 is tilted toward the dust receiving frame 5 so that impurities accumulated on the filter plate 7 fall into the dust receiving frame 5 for collection to avoid clogging of the filter holes on the filter plate 7. Rainwater passing through the filter screen 6 falls on the filter plate 7 to flush the filter plate 7, and cooperates with the water outlet hole 05 on the dust receiving frame 5 to allow rainwater entering the dust receiving frame 5 to flow out into the drainage trough 2 without accumulating in the dust receiving frame 5, further avoiding affecting the rainwater from entering the underground drainage pipe and improving the drainage effect. Therefore, the collection box 4 and the dust receiving frame 5 collect impurities in the rainwater intercepted by the filter screen 6 and the filter plate 7 respectively, preventing the filter screen 6 and the filter plate 7 from clogging and affecting drainage, requiring cleaners to frequently remove the filter screen 6 and the filter plate 7 for cleaning, thereby reducing the cleaning burden of cleaners and having high practicality.

[0023] An L-shaped pull rod 8 is provided on the collection box 4, and a positioning groove 9 corresponding to the pull rod 8 is opened on the drainage trough 2. One end of the pull rod 8 is hinged on the collection box 4, and the other end of the pull rod 8 is inserted into the positioning groove 9. A movable groove 10 corresponding to the filter screen 6 and the filter plate 7 is opened on the drainage trough 2. A movable rod 11 slidably connected to the movable groove 10 is installed on the filter screen 6 and the filter plate 7. A connecting rod 12 is installed between the two movable rods 11. A handle 13 is installed on the movable rod 11 on the filter screen 6. Two card slots 14 corresponding to the two ends of the movable rod 11 are opened on the inner wall of the movable groove 10. The two ends of the movable rod 11 slide in the two card slots 14 respectively and are respectively engaged with the two card slots 14;

[0024] When the impurities collected in the collection box 4 and the dust collecting frame 5 need to be cleaned out for subsequent use, the manhole cover 3 is removed from the drainage trough 2, and the movable rods 11 on the filter screen 6 and the filter plate 7 slide in the movable groove 10 and the connecting rod 12 connects the two movable rods 11, and cooperates with the filter screen 6 and the filter plate 7 to be hinged to the collection box 4 and the dust collecting frame 5 respectively, so as to pull the handle 13 to make the two movable rods 11 slide out of the movable groove 10 and the card slot 14, so as to facilitate the removal of one end of the filter screen 6 and one end of the filter plate 7 from the inner wall of the drainage trough 2, and cooperate with the dust collecting frame 5 to be installed on the collection box 4, and the collection box 4 is inserted into the positioning groove 9 through the pull rod 8. The rod 8 is pulled out from the positioning groove 9, making it easy to disassemble the collection box 4 and the dust collecting frame 5 from the inner wall of the drainage trough 2, and then making it easy to take the collection box 4 and the dust collecting frame 5 out of the drainage trough 2 for cleaning. At the same time, the filter screen 6 and the filter plate 7 are also taken out of the drainage trough 2 for cleaning, which is convenient for subsequent better use and further improves practicality; the two ends of the movable rod 11 slide in the two card slots 14 respectively and are respectively engaged with the two card slots 14, making it easy to disassemble the filter screen 6 and the filter plate 7 from the inner wall of the drainage trough 2, while making the filter screen 6 and the filter plate 7 firmly connected to the inner wall of the drainage trough 2 when filtering rainwater, and will not affect the use of the filter screen 6 and the filter plate 7.

[0025] A fixing rod 15 is provided on the dust collecting frame 5, and both ends of the fixing rod 15 are respectively threadedly connected to a connecting screw 16. The two connecting screws 16 are respectively installed on the dust collecting frame 5 and the collecting box 4. While realizing the connection between the dust collecting frame 5 and the collecting box 4, the fixing rod 15 threadedly connected to the connecting screw 16 is rotated to disconnect one end of the fixing rod 15 from the connecting screw 16 installed on the collecting box 4, thereby facilitating the removal of the dust collecting frame 5 from the collecting box 4, and then facilitating the cleaning of impurities collected in the dust collecting frame 5, thereby improving practicality.

[0026] A guide pipe 17 connected to the underground drainage pipe is installed at the bottom of the drainage trough 2. The drainage trough 2 and the underground drainage pipe are connected through the guide pipe 17. The bottom of the drainage trough 2 is inclined to the guide pipe 17 to facilitate the rainwater in the drainage trough 2 to flow better into the guide pipe 17 and enter the underground drainage pipe, thereby avoiding rainwater accumulation at the bottom of the drainage trough 2.

[0027] The drainage trough 2 includes an installation groove 18 that cooperates with the manhole cover 3. An elastic block 19 that interferes with the manhole cover 3 is fixed in the installation groove 18. The manhole cover 3 interferes with the elastic block 19 in the installation groove 18 to facilitate the manhole cover 3 to be more stably installed in the groove of the drainage trough 2. The elastic block 19 includes an inclined surface to facilitate the installation of the manhole cover 3.
