[0046] The technical solution of the present utility model is described in detail below in conjunction with the specific drawings.
[0047] like Figure 1As shown, a roadbed drainage structure for highway road construction includes: a drainage channel 1, a filter plate 2 and a cleaning component 3, the filter plate 2 is horizontally arranged in the drainage channel 1, the filter plate 2 includes at least two mutually parallel first strip members 21, one end of each first strip member 21 is fixed to the inner wall of the drainage channel 1, and the other end is abutted against the cleaning component 3, and each first strip member 21 is equidistantly distributed, and a first gap 22 is formed between two adjacent first strip members 21; the cleaning component 3 includes a cleaning rod 31, the cleaning rod 31 is rotatably arranged in the first gap 22, and each cleaning rod 31 can pass through each first gap 22 during rotation to dredge the first gap 22.
[0048] In this embodiment, the filter plate of the utility model is used to filter sewage flowing through the drainage channel, and the debris and garbage in the sewage are blocked by the mutually parallel first strips 21, and the sewage flows out through the first gap 22. The cleaning component is used to clean the debris and garbage on the first strip 21 to prevent the filter plate from being blocked by too much garbage. The cleaning rod rotates from bottom to top to remove the dirt and garbage blocking or covering the first gap 22, and as the cleaning rod continues to rotate, the dirt and garbage can be driven away from the filter plate by the cleaning rod to achieve the cleaning function.
[0049] In this embodiment, one end of each first strip 21 is fixed to the same crossbar, so that at least two mutually parallel first strips 21 form a complete board structure, thereby improving the structural strength. Accordingly, in this embodiment, a plurality of cleaning rods 31 are provided, and each cleaning rod 31 is rotatably provided in the first gap 22, and each cleaning rod 31 can pass through each first gap 22 during rotation. It is easy to imagine that a plurality of cleaning rods 31 can be equidistantly provided to form a board structure and rotate simultaneously, thereby improving its cleaning efficiency.
[0050] During the specific use of the cleaning component 3, each cleaning rod 31 is in an initial state of vertically downward. When the filter plate 2 needs to be cleaned, such as when there is too much dirt and garbage on the filter plate 2, or when it is cleaned regularly, each cleaning rod 31 can rotate from bottom to top and pass through the first gap 22 to clean the garbage covering the first gap 22 to prevent the first gap 22 from being blocked.
[0051] like Figure 1 and Figure 2 As shown, the cleaning assembly 3 also includes a rotating shaft 32 and a driving assembly 33. The rotating shaft 32 is arranged along the width direction of the filter plate 2, and each cleaning rod 31 is evenly distributed on the rotating shaft 32 along the axial direction of the rotating shaft 32; the rotating shaft 32 is connected to the driving assembly 33, and the driving assembly 33 is used to drive the rotating shaft 32 to rotate. The driving assembly 33 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the cleaning rod 31 to rotate and clean the first gap 22.
[0052] like Figure 2 and Figure 3 As shown, the driving assembly 33 includes a gear set 331, a connecting rod 332 and a handle 333, one end of the connecting rod 332 is connected to the handle 333, the other end of the connecting rod 332 is connected to the power input end of the gear set 331, and the power output end is connected to the rotating shaft 32.
[0053] In this embodiment, the gear set 331 is a reversing mechanism, and the connecting rod 332 is arranged perpendicularly to the rotating shaft 32, so that the connecting rod 332 can extend out of the drainage channel 1, which is convenient for manual control of cleaning. The handle 333 can rotate to drive the connecting rod 332 to rotate, and the connecting rod 332 drives the power input end of the gear set 331 to rotate in the horizontal direction, and the output end of the gear set 331 is reversed to rotate in the vertical direction, thereby causing the rotating shaft 32 to rotate on the vertical plane.
[0054] In this embodiment, the gear set 331 includes a worm wheel 3312 and a worm 3311 that mesh with each other. The worm wheel 3312 and the rotating shaft 32 are coaxially connected, and the worm 3311 and the connecting rod 332 are coaxially connected.
[0055] like Figure 1-Figure 3 As shown, the cleaning assembly 3 further includes a plurality of shielding rods 34 , and each shielding rod 34 is configured to be symmetrically distributed on the rotating shaft 32 along the axis of the rotating shaft with each cleaning rod 31 .
[0056] In this embodiment, each shielding rod 34 and each cleaning rod 31 are always kept in the same straight line, and the shielding rod 34 is used to prevent unfiltered sewage from flowing out of the drainage channel 1. At the same time, the shielding rod 34 can rotate synchronously with the cleaning rod 31 to achieve the same function as the cleaning rod 31, so as to improve the efficiency of cleaning the first gap 22.
[0057] like Figure 1 As shown, a roadbed drainage structure for highway road construction also includes a dirt collection chamber 4, which is arranged on one side of the drainage channel 1 and is connected to the drainage channel 1; each cleaning rod 31 is rotatably installed at the connection between the dirt collection chamber 4 and the drainage channel 1, and each cleaning rod 31 can clean the dirt accumulated on the first gap 22 into the dirt collection chamber 4 during rotation. The shielding rod 34 is used to prevent unfiltered sewage from flowing into the dirt collection chamber 4. The dirt collection chamber 4 is used to collect garbage and dirt cleaned by the cleaning rod 31, so as to facilitate centralized cleaning by the staff.
[0058] Specifically, in the initial state, the cleaning rod 31 is in a vertically downward initial state, and the shielding rod 34 is in a vertically upward initial state. The sewage flows into the drainage channel 1 and is filtered by the filter plate 2 and the shielding rod 34. The magazine garbage adheres to the filter plate 2 and the shielding rod 34. The rotating shaft 32 drives the cleaning rod 31 and the shielding rod 34 to rotate 180 degrees. The cleaning rod 31 dredges the filter plate 2. Since the cleaning rod 31 is in a vertically upward state and the position of the shielding rod 34 changes at this time, the magazine garbage on the cleaning rod 31 and the shielding rod 34 falls into the dirt collection chamber 4 due to gravity.
[0059] like Figure 1 and Figure 2 As shown, a collecting assembly 5, a guide plate 6 and an extension plate 7 are provided in the dirt collecting chamber 4, one end of the guide plate 6 is abutted against the cleaning assembly 3, and the other end of the guide plate 6 is abutted against the collecting assembly 5 through the extension plate 7; the collecting assembly 5 is configured to be able to approach or move away from the other end of the guide plate 6.
[0060] The guide plate 6 is used to transmit the garbage and dirt cleaned by the cleaning rod 31, and guides the garbage and dirt into the collecting assembly 5. The guide plate 6 abuts against the collecting assembly 5 through the extension plate 7 to prevent the garbage and dirt on the guide plate 6 from falling outside the collecting assembly 5.
[0061] like Figure 1 and Figure 2 As shown, the guide plate 6 is tilted in the horizontal direction, and the guide plate 6 includes at least two second strips 61 parallel to each other, one end of each second strip 61 abuts against the cleaning component 3, and the other end abuts against the collecting component 5 through the extension plate 7; and each second strip 61 is equidistantly distributed, and a second gap 62 is formed between two adjacent second strips 61, and each cleaning rod 31 can pass through each second gap 62 during the rotation process. The cleaning rod can pass through the second gap 62 on the guide plate to transfer the garbage and dirt on the cleaning rod to the guide plate. At the same time, the guide plate is tilted in the horizontal direction. It is easy to think that the end of the guide plate close to the cleaning component is higher than the end close to the collecting component, so that the garbage and dirt on the guide plate can fall into the collecting component under the action of gravity.
[0062] like Figure 1 As shown, a roadbed drainage structure for highway road construction also includes a cleaning channel 8, which is connected to the dirt collection chamber 4; the collecting assembly 5 is movably arranged between the cleaning channel 8 and the dirt collection chamber 4. The cleaning channel 8 connects the dirt collection chamber 4 with the outside, so that after the collecting assembly 5 is full of garbage and dirt, the garbage and dirt can be discharged through the cleaning channel 8.
[0063] like Figure 1 and Figure 2As shown, the collecting assembly 5 includes a collecting frame 51, a connecting rod 52 and a cover plate 53. The cover plate 53 covers the cleaning channel 8. The cover plate 53 is connected to the collecting frame 51 through the connecting rod 52. The collecting frame 51 abuts against the other end of the guide plate 6 and can move closer to or away from the other end of the guide plate 6 driven by the cover plate 53. The cover plate 53 is used to cover the cleaning channel 8 to prevent external debris from falling into the cleaning channel 8. At the same time, since the cover plate 53 is connected to the collecting frame 51 through the connecting rod 52, the collecting frame 51 can be driven to move when the staff moves the cover plate 53, which is convenient for the staff to handle the garbage and dirt in the collecting frame 51.
[0064] like Figure 2 As shown, a plurality of through holes 511 are formed on the collecting frame 51. The through holes 511 on the collecting frame 51 are helpful to discharge the residual water in the impurities in the collecting frame 51.
