Technical Field
[0001] The utility model relates to the technical field of roadbed and pavement structures, in particular to a road bridge and roadbed pavement drainage structure. Background Art
[0002] With the rapid development of transportation and the improvement of highway grades, there are more and more highways. When the road surface is subjected to the influence of vibration, impact, tension and shear properties of repeated vehicle loads, as well as expansion and contraction caused by temperature and climate changes, fine cracks often appear, causing bridge deck seepage or leakage, affecting the durability of the road surface. The road surface refers to a layered structure paved on the roadbed with various road construction materials to directly bear vehicle loads. A good quality road surface should have sufficient strength and good stability, and its surface should meet the requirements of flatness, density and anti-skid. The road surface structure consists of a surface layer, a base layer and a cushion layer. The road surface engineering includes road base (subbase) construction technology, asphalt pavement construction technology, cement concrete pavement construction technology, road waterproofing and drainage construction technology, special asphalt concrete pavement construction technology, road surface testing and detection technology, etc.
[0003] At present, in the market, some road bridge subgrade and pavement drainage structures have the problem of accumulated water falling with a lot of foreign matter entering into them, which cannot be handled centrally, often causing blockage and inconvenient cleaning. Therefore, we propose a road bridge subgrade and pavement drainage structure to solve the above problem. Utility Model Content

When there are too many foreign matter, the foreign matter blocks the first water leakage hole, and the accumulated water entering from the floor drain will squeeze the top of the foreign matter, causing the foreign matter to push the baffle to flip over. The baffle rotates under the weight of the foreign matter, squeezing the elastic mechanism, and a sewage collecting plate is provided in the base through rotation, and a second water leakage hole is provided on the sewage collecting plate.

The baffle flips counterclockwise to re-close the opening at the top of the water tank, and drives the sewage collecting plate to rotate counterclockwise at the same time, dumping the foreign matter on the surface of the sewage collecting plate into the left chamber for collection. The utility model thus facilitates the centralized collection of foreign matter, avoids blockage, and is easy to clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] An elastic mechanism is provided in the base 1 for pressing the baffle 5 against one side of the top opening of the water reservoir 3;
[0027] A dirt collecting plate 11 is rotatably provided in the base 1, and a second water leakage hole 1101 is provided on the dirt collecting plate 11. A partition 12 is fixed to the bottom wall of the base 1, and the partition 12 is used to separate the bottom wall of the base 1 into two chambers.
[0028] The dirt collecting plate 11 and the elastic mechanism are coordinated through a linkage structure. When the baffle 5 is squeezed by foreign matter, the elastic mechanism contracts, and the baffle 5 flips clockwise, while driving the dirt collecting plate 11 to rotate clockwise; when the baffle 5 is not squeezed by foreign matter, the elastic mechanism resets, and the baffle 5 flips counterclockwise, while driving the dirt collecting plate 11 to rotate counterclockwise.
[0029] In this embodiment, the accumulated water falls freely onto the inclined plate 4 through the floor drain 2, and the accumulated water enters the water reservoir 3 through the first water leakage hole 401. The foreign matter carried in the accumulated water accumulates on the side of the baffle 5 through the inclined plate 4. When there are too many foreign matter, the foreign matter blocks the first water leakage hole 401, and the accumulated water entering from the floor drain 2 will squeeze the top of the foreign matter, causing the foreign matter to push the baffle 5 to flip over. The baffle 5 rotates under the weight of the foreign matter, squeezing the elastic mechanism, and a sewage collecting plate 11 is provided by rotating in the base 1. The sewage collecting plate 11 is provided with a second water leakage hole 1101, and a partition 12 is fixed to the bottom wall inside the base 1. The partition 12 is used to separate the bottom wall inside the base 1 into two chambers; the sewage collecting plate 11 and the elastic mechanism are coordinated through a linkage structure.
[0030] Then, when the baffle 5 is squeezed by foreign matter, the elastic mechanism contracts, and the baffle 5 flips clockwise, and at the same time drives the sewage collecting plate 11 to rotate clockwise, and the accumulated water and foreign matter will fall freely onto the sewage collecting plate 11 at the same time, and the foreign matter will remain on the surface of the sewage collecting plate 11 after the water is controlled through the second water leakage hole 1101; after the accumulated water and foreign matter have fallen off, the baffle 5 is no longer squeezed by foreign matter, and the elastic mechanism is reset, then the baffle 5 flips counterclockwise to re-close the top opening of the water tank 3, and at the same time drives the sewage collecting plate 11 to rotate counterclockwise, dumping the foreign matter on the surface of the sewage collecting plate 11 into the left chamber for collection.
[0031] As a further solution of the present invention, a drain hole 13 communicating with the interior of the chamber is opened on one side of the shell of the water reservoir 3, and a drain pipe 14 is fixed on the other side of the shell.
[0032] In this embodiment, the water controlled by the sewage collecting plate 11 enters the chamber on the right side of the partition 12, then enters the water reservoir 3 through the drain hole 13, and finally is discharged outward through the drain pipe 14.
[0033] As a further solution of the present utility model, the linkage structure includes a cylinder 6 fixed to the inner top wall of the base 1, an inner rod 7 is inserted through the cylinder 6, an annular limit block 9 is fixed on the inner rod 7, and a first spring 8 is provided inside the cylinder 6 and is sleeved on the inner rod 7. The first spring 8 is located between the inner wall of one end of the cylinder 6 and the annular limit block 9, and one end of the inner rod 7 is fixed with a dome 10 that is pressed against the baffle 5.
[0034] In this embodiment, accumulated water enters the water reservoir 3 through the first water leakage hole 401, and foreign matter carried in the accumulated water accumulates on one side of the baffle 5 through the inclined plate 4. When there are too many foreign matter, the foreign matter blocks the first water leakage hole 401, and the accumulated water entering from the floor drain 2 will squeeze the top of the foreign matter, causing the foreign matter to push the baffle 5 to flip over. When the baffle 5 flips over, it will squeeze the dome 10, drive the inner rod 7 to move, and make the annular limit block 9 on the inner rod 7 squeeze the first spring 8. When the baffle 5 is no longer squeezed by foreign matter, the first spring 8 is reset under the action of elastic force, pushing the annular limit block 9 to slide in the cylinder 6, driving the inner rod 7 to move and using the dome 10 to push the baffle 5 to flip and reset.
[0035] As a further solution of the present invention, the linkage structure includes a main shaft 16 and a secondary shaft 18 rotatably mounted on the base 1 through bearings, a rack plate 15 is fixed to one end of the inner rod 7, a gear 17 meshing with the rack plate 15 is fixed to the main shaft 16, and the main shaft 16 and the secondary shaft 18 are connected by a transmission mechanism 19.
[0036] In this embodiment, when the inner rod 7 moves, it will synchronously drive the rack plate 15 to move, and the rack plate 15 is engaged with the gear 17 to drive the gear 17 to rotate, thereby driving the main shaft 16 to rotate, and then driving the secondary shaft 18 to rotate.
[0037] As a further solution of the present invention, the transmission mechanism 19 includes a first pulley 1901 fixed to one end of the main shaft 16 and a second pulley 1902 fixed to one end of the secondary shaft 18 , and the first pulley 1901 and the second pulley 1902 are connected via a belt 1903 .
[0038] In this embodiment, the rotation of the main shaft 16 drives the first pulley 1901 to rotate, thereby utilizing the transmission connection between the first pulley 1901 and the second pulley 1902 through the belt 1903 to drive the second pulley 1902 to rotate the rod and thus drive the secondary shaft 18 to rotate.
[0039] As a further solution of the present invention, a groove body 20 is opened inside the end of the sewage collecting plate 11 close to the water tank 3, and an extension plate 21 is movably connected inside the groove body 20. The extension plate 21 is fixedly connected to the inner wall of the groove body 20 by a second spring 22.
[0040] In this embodiment, the extension plate 21 can be slightly extended and contracted inside the trough body 20 under the action of the elastic force of the second spring 22, so that when the sewage collecting plate 11 is flipped over, the extension plate 21 can be extended and contracted so that there is no gap between it and the outer wall of the water tank 3, thereby preventing foreign matter from falling into the chamber through the gap.
[0041] As a further solution of the present invention, a first inspection door 23 and a second inspection door 24 are respectively hingedly mounted on the base body 1 and located on the front sides of the two chambers.
[0042] In this embodiment, the first inspection door 23 and the second inspection door 24 facilitate post-inspection and maintenance of the interiors of the two chambers, and also facilitate removal of foreign matter from the chambers.
[0043] The working principle of the utility model is: the accumulated water falls freely onto the inclined plate 4 through the floor drain 2, and the accumulated water enters the water reservoir 3 through the first water leakage hole 401. The foreign matter carried in the accumulated water accumulates on the side of the baffle 5 through the inclined plate 4. When there are too many foreign matter, the foreign matter blocks the first water leakage hole 401, and the accumulated water entering from the floor drain 2 will squeeze the top of the foreign matter, so that the foreign matter pushes the baffle 5 to flip over. The baffle 5 rotates under the weight of the foreign matter, squeezing the elastic mechanism, and a sewage collecting plate 11 is provided through the rotation inside the base 1. The sewage collecting plate 11 is provided with a second water leakage hole 1101, and a partition 12 is fixed to the bottom wall inside the base 1. The partition 12 is used to separate the bottom wall inside the base 1 into two chambers; the sewage collecting plate 11 and the elastic mechanism are coordinated through a linkage structure.
[0044] Then, when the baffle 5 is squeezed by foreign matter, the elastic mechanism contracts, and the baffle 5 flips clockwise, and at the same time drives the sewage collecting plate 11 to rotate clockwise, and the accumulated water and foreign matter will fall freely onto the sewage collecting plate 11 at the same time, and the foreign matter will remain on the surface of the sewage collecting plate 11 after the water is controlled through the second water leakage hole 1101; after the accumulated water and foreign matter have fallen off, the baffle 5 is no longer squeezed by foreign matter, and the elastic mechanism is reset, then the baffle 5 flips counterclockwise to re-close the top opening of the water tank 3, and at the same time drives the sewage collecting plate 11 to rotate counterclockwise, dumping the foreign matter on the surface of the sewage collecting plate 11 into the left chamber for collection.
[0045] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
