DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a road bridge drainage device includes a filter box 20, which is a rectangular tube. A collecting box 21 is fixedly connected to the front wall of the filter box 20. The collecting box 21 is a hollow rectangular box with an open top. When in use, the filter box 20 is installed on the bridge deck, and the bottom of the filter box 20 is connected to the drainage pipe. This is an existing technology and will not be described in detail here.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cleaning structure can remove the debris blocked in the cavity of the filter box 20. The cleaning structure includes: a filter plate 30, a filter slot 31 and a top column 34. The filter plate 30 is fixedly connected to the top opening of the filter box 20, the filter slot 31 is opened through the top of the filter plate 30, the top column 34 is slidably connected in the cavity of the filter box 20, the filter plate 30 is tilted at the top opening of the filter box 20, and the top column 34 can enter the filter slot 31.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the filter plate 30 can block the top opening of the filter box 20. The filter groove 31 is a circular groove, and the filter groove 31 can fit the shape of the top column 34. A plurality of filter grooves 31 are evenly arranged on the wall surface of the filter plate 30. The cleaning structure further includes a moving groove 32, a moving plate 33, a moving block 35 and a leakage groove 36. The moving grooves 32 are symmetrically arranged on both sides of the cavity of the filter box 20. The moving plate 33 is slidably connected to the cavity of the filter box 20. The top column 34 is fixedly connected to the top of the moving plate 33. The moving blocks 35 are symmetrically and fixedly connected to the two side walls of the moving plate 33. The leakage groove 36 is arranged at the rear position of the top of the moving plate 33. A plurality of top columns 34 are arranged on the top of the moving plate 33. The number and position of the top columns 34 correspond to the bottom of each filter groove 31. The distance between the top of each top column 34 and each filter groove 31 is the same as the length of the moving groove 32. The moving groove 32 can fit the sliding of the moving block 35. The moving block 35 vertically slides up and down in the moving groove 32. The cleaning structure further includes a touch block 37, a guiding plate 38, a rotating shaft 40, a trigger fan 41 and a touch plate 42. The touch blocks 37 are symmetrically and fixedly connected to the two sides of the bottom of the moving plate 33. The guiding plate 38 is fixedly connected to the wall surface of the filter box 20 vertically below the leakage groove 36. The rotating shaft 40 is rotatably connected to the cavity of the filter box 20 below the moving plate 33. The trigger fan 41 is fixedly connected to the wall surface of the rotating shaft 40. The touch plates 42 are symmetrically and fixedly connected to the two side walls of the rotating shaft 40. The symmetric touch plates 42 are respectively rotatably connected to both sides of the cavity of the filter box 20. The top of the guiding plate 38 is in a slope shape. The rotating shaft 40 is in a cylindrical shape. A plurality of trigger fans 41 are arranged in a circular array on the arc surface of the rotating shaft 40. The top of the touch plate 42 is in an arc shape. The bottom of the touch block 37 is also in an arc shape. The top of the touch plate 42 can contact the bottom arc surface of the touch block 37;

[0030] During specific use, the water flow moves along the bridge deck into the cavity of the filter box 20. When the water flow moves into the cavity of the filter box 20, it will flow into the cavity of the filter box 20 along the filter groove 31 on the top of the filter plate 30. When the water flow passes through the filter groove 31, it will fall on the bottom of the moving plate 33, and then move to the inclined surface of the guiding plate 38 along the leakage groove 36 on the wall surface of the moving plate 33, and then move to the wall surface of the trigger fan 41, and then impulse the trigger fan 41 downward. Then the water flow will directly enter the drain pipe for discharge. When the trigger fan 41 is impulsed by the water flow, it will drive the rotating shaft 40 and the touch plate 42 to rotate in the cavity of the filter box 20. The touch plate 42 will contact the bottom arc surface of the touch block 37 when rotating to the vertical state, and will lift the moving plate 33 upward through the touch block 37. When the moving plate 33 is lifted, the moving block 35 will simultaneously slide upward in the moving groove 32. The moving plate 33 will also drive all the top columns 34 to move upward simultaneously and make each top column 34 enter each filter groove 31 at the corresponding position. At this time, when the top column 34 penetrates the filter groove 31, it will eject all the sundries on the top of the filter plate 30 and the blocked sundries in the filter groove 31. After the sundries are ejected by the top column 34, they will enter the cavity of the collection box 21 along the inclined surface of the filter plate 30 and accumulate;

[0031] In summary, by setting up the cleaning structure, not only can the blocked sundries be cleaned, but also the sundries can be concentrated and piled up in the same position. Moreover, due to the inclined surface of the filter plate 30, the ejected sundries will not be blocked again on the wall surface of the filter plate 30 in this solution.

[0032] As Figure 1 and Figure 5 shown, a connecting groove 22 is formed on the rear wall surface of the collection box 21. The collection box 21 is connected to the cavity of the filter box 20 through the connecting groove 22. An auxiliary block 23 is fixedly connected inside the collection box 21. The auxiliary block 23 is a right-angled triangular block with an inclined surface facing upward.

[0033] During specific use, when the inside of the collection box 21 needs to be cleaned, the cleaner can directly use a broom to sweep the sundries inside the collection box 21 along the inclined surface of the auxiliary block 23.

[0034] In summary, by setting up the auxiliary block 23, it is convenient to clean the inside of the collection box 21. Because the inclined surface of the auxiliary block 23 will seamlessly connect with the lowest part inside the collection box 21, the sundries piled up inside the collection box 21 can be directly cleaned.

[0035] Working principle: The water flow moves along the bridge surface into the cavity of the filter box 20. When the water flow moves into the cavity of the filter box 20, it will flow into the cavity of the filter box 20 along the filter groove 31 at the top of the filter plate 30. When the water flow passes through the filter groove 31, it will fall on the bottom of the moving plate 33, and then move along the leakage groove 36 on the wall surface of the moving plate 33 to the inclined surface of the guiding plate 38, and then move to the wall surface of the trigger fan 41, and then impulse the trigger fan 41 downward. Then the water flow will directly enter the drain pipe for discharge. When the trigger fan 41 is impulsed by the water flow, it will drive the rotating shaft 40 and the touch plate 42 to rotate inside the filter box 20. The touch plate 42 will contact the bottom arc surface of the touch block 37 when rotating to the vertical state, and push the moving plate 33 upward through the touch block 37. When the moving plate 33 is pushed upward, the moving block 35 will simultaneously slide upward in the moving groove 32. The moving plate 33 will also drive all the top columns 34 to move upward simultaneously and make each top column 34 enter each filter groove 31 at the corresponding position. At this time, when the top column 34 penetrates the filter groove 31, all the sundries on the top of the filter plate 30 and the blocked sundries in the filter groove 31 will be ejected. After the sundries are ejected by the top column 34, they will enter the cavity of the collection box 21 along the inclined surface of the filter plate 30 and pile up.
