Description

Technical Field

[0001] The utility model relates to the technical field of separation, in particular to a road bridge, roadbed and pavement drainage and filtering structure. Background Art

[0002] Roads, as public passages connecting cities, urban and rural areas, and villages, are approved by the transportation management department to allow cars to pass, which covers officially confirmed built roads. Bridges are a structure that crosses obstacles. They are composed of a carefully designed upper part (bridge body and bridge deck), a lower part (bridge piers and abutments), and a foundation (such as open cut, pile foundation, caisson, caisson, pipe column and cap, etc.) to form a stable overhead passage. Drainage systems are carefully arranged on both sides of the road and bridge. The main form is excavated drainage grooves, which are cleverly connected to the overall drainage network of roads and bridges to achieve effective collection and centralized treatment of rainwater. However, since rainwater needs to flow through a long pipe before being discharged into natural water bodies or treatment plants, if it is mixed with large particles of impurities, it is very easy to cause pipe blockage or filter blockage. Therefore, clear requirements are put forward for the particle size of impurities in drainage. At present, the common drainage facility design is to set a metal filter on the top of the filter panel, and the bottom of the panel is directly connected to the drainage pipe. Although this design can initially filter impurities in rainwater, over time, the mixture of rainwater and sediment will continue to pass through the metal mesh into the filter panel and then flow into the pipe. Over time, a large amount of sediment is likely to accumulate inside the pipe, which not only reduces drainage efficiency, but also increases the difficulty and complexity of pipe cleaning.

[0006] The filtering mechanism further comprises a drainage pipe vertically fixedly arranged at the center of the filter panel, the outer wall of the drainage pipe is evenly provided with a plurality of filtering holes along its circumferential direction, and the inner bottom of the filter panel is provided with an annular groove;

[0007] A floating plate is movably arranged on the drainage pipe, and the floating plate divides the plurality of filtering holes into two parts, an upper part and an lower part. When a blockage occurs in the filtering panel, the floating plate moves upward under the action of water buoyancy, so that the drainage area of ​​the lower part of the plurality of filtering holes is increased;

[0008] An anti-clogging component is arranged inside the filter panel, and the anti-clogging component is connected to the floating plate. When the floating plate is subjected to a downward external force, the anti-clogging component will cooperate with the floating plate to clean the plurality of filter holes.

[0012] As a further solution of the utility model:

[0013] The floating plate is provided with a plurality of through holes evenly distributed along the circumference, and the through holes can allow the mud and sand to fall smoothly into the annular groove;

[0014] A side of the floating plate close to the filter panel is configured as a first inclined surface inclined toward the top column, and a side of the floating plate close to the drain pipe is configured as a second inclined surface inclined toward the filter panel.

[0015] As a further solution of the utility model:

[0016] The anti-blocking assembly includes a driving rod vertically fixedly arranged at the bottom end of the top column and a sleeve movably sleeved outside the driving rod;

[0017] A circular ring is fixedly arranged on the inner wall of the drainage pipe, and a plurality of connecting rods are evenly fixedly arranged on the outer wall of the sleeve along its circumference, and the plurality of connecting rods are all slidably matched with the circular ring.

[0020] As a further solution of the utility model:

[0021] The outer wall of the driving rod is provided with a spiral groove, and the inner wall of the sleeve is rollingly embedded with a ball, and the ball is rollingly embedded in the spiral groove.

[0022] As a further solution of the utility model:

[0023] The outer wall of the sleeve is evenly provided with a plurality of support frames along its circumference, and a wire brush is fixedly provided on the support frame. The wire brush fits the inner wall of the drain pipe and corresponds to the position of the filter hole.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] Through the annular groove set at the bottom of the filter panel and the multiple filter holes on the drainage pipe, the muddy water on the bridge first passes through the metal filter and then falls into the annular groove for sedimentation, and impurities such as mud and stones are left in the annular groove, and then the clean water is discharged through the multiple filter holes, thereby avoiding the blockage of the pipeline; when it is necessary to clean the mud and stones in the annular groove, the hexagon socket bolts are loosened with the help of tools to remove the filter panel from the base plate;

[0026] Since the floating plate divides the multiple filter holes into two parts, when the multiple filter holes are blocked by light objects such as weeds, the drainage volume will decrease, causing the liquid level inside the filter panel to rise, and the floating plate will move upward under the action of water buoyancy, increasing the drainage area of ​​the multiple filter holes below the floating plate;

[0027] In addition, when the floating plate is subjected to the downward external force of the wheel, the floating plate will drive the anti-clogging component to operate, thereby cleaning the multiple filter holes and removing the blockages in the filter holes. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] A floating plate 6 is movably provided on the drainage pipe 5, and the floating plate 6 divides the plurality of filter holes 501 into two parts, an upper part and an lower part. When a blockage occurs in the filter panel 2, the floating plate 6 moves upward under the action of water buoyancy, so that the drainage area of ​​the lower part of the plurality of filter holes 501 is increased;

[0044] An anti-clogging component is disposed inside the filter panel 2 , and the anti-clogging component is connected to the floating plate 6 . When the floating plate 6 is subjected to a downward external force, the anti-clogging component and the floating plate 6 cooperate with each other to clean the multiple filter holes 501 .

[0045] In this solution, through the annular groove 201 set at the bottom of the filter panel 2 and the multiple filter holes 501 on the drain pipe 5, the muddy water on the bridge first passes through the metal filter 4 and then falls into the annular groove 201 for sedimentation, and impurities such as mud and stone are left in the annular groove 201, and then the clean water is discharged through the multiple filter holes 501, thereby avoiding clogging of the pipeline; when it is necessary to clean the mud and stone in the annular groove 201, the hexagon socket bolt 3 is loosened with a tool, so that the filter panel 2 is removed from the base plate 1;

[0046] Since the floating plate 6 divides the plurality of filter holes 501 into two parts, the drainage volume will decrease when the plurality of filter holes 501 are blocked by light objects such as weeds, so that the liquid level inside the filter panel 2 rises, and the floating plate 6 moves upward under the action of the water buoyancy, so that the drainage area of ​​the plurality of filter holes 501 located below the floating plate 6 increases;

[0050] In this embodiment, since the slide bar 601 is located inside the slide groove 502 and slides with each other, the sliding cooperation between the floating plate 6 and the drain pipe 5 is achieved;

[0051] Since the top of the top column 602 passes through the drain pipe 5 and the metal filter 4 respectively, when the liquid level in the filter panel 2 rises, the float plate 6 will move upward due to the buoyancy and drive the top of the top column 602 to be pushed out of the metal filter 4 through the slide rod 601.

[0058] The driving rod 7 is fixedly connected to the top column 602 , so when the top column 602 is subjected to wheel pressure, it will drive the driving rod 7 to move vertically downward.

[0059] As a further solution of the utility model, a T-shaped rod 11 is fixedly provided on the top of the connecting rod 10, a T-shaped ring groove 901 is opened on the bottom surface of the ring 9, and the T-shaped rod 11 is located inside the T-shaped ring groove 901 and slides with each other.

[0064] As a further solution of the utility model, a plurality of support frames 13 are evenly arranged along the circumference of the outer wall of the sleeve 8 , and a wire brush 14 is fixedly arranged on the support frame 13 . The wire brush 14 fits the inner wall of the drain pipe 5 and corresponds to the position of the filter hole 501 .

[0065] In this embodiment, since the wire brush 14 is in contact with the inner wall of the drain pipe 5 and corresponds to the position of the filter holes 501 , during the rotation of the sleeve 8 , the wire brush 14 will rotate along with the sleeve 8 to clean the multiple filter holes 501 .
