Technical Field
[0001] The utility model relates to the technical field of bridge drainage, in particular to a drainage device for bridge expansion joints. Background Art
[0002] A bridge refers to a building for railways, roads, channels, pipelines, etc. to cross rivers, valleys or other traffic lines. In order to meet the requirements of bridge deck deformation and enable it to adapt to displacements caused by temperature changes, concrete shrinkage and load effects, expansion joints are usually set on the bridge. In order to prevent rainwater from accumulating in the expansion joint and eroding the rubber sealing strip, it is necessary to drain the rainwater in the expansion joint.
[0003] In the existing related technologies, the following defects often exist: A bridge expansion joint usually has a warped head at one end, which can prevent rainwater and sundries from directly draining under the bridge through the expansion joint, thereby protecting the bridge structure from damage. However, due to factors such as the warped head of the bridge expansion joint being easily overlooked in design and inconvenient in construction procedures, existing bridges do not have warped heads. The bridge expansion joints without warped heads often easily cause rainwater to drain to both sides along the bridge cross slope, which is likely to pollute the beam body and scour the conical slope under the bridge.
[0004] Therefore, the utility model provides a drainage device for bridge expansion joints. Summary of the Utility Model

[0010] Preferably, two inclined platforms are fixedly connected to the upper surface of the filter sleeve plate, and a surrounding plate is fixedly connected to the upper surface of the filter sleeve plate.
[0011] The effects achieved by the above components are as follows: By setting the surrounding plate and the inclined platforms, the position of the rainwater can be restricted to ensure that the rainwater flows down through the filter holes on the filter sleeve plate.
[0012] Preferably, first chutes are provided on the inner walls of the two side beams, first sliders are slidably connected to the surfaces of the first chutes on the two side beams, and a mounting plate is fixedly connected to the lower surface of the first slider.

[0018] Preferably, a scraping plate is fixedly connected to one end of the sliding rod away from the spring, and the scraping plate is in close fit with the inclined platform.
[0019] The effects achieved by the above components are as follows: By setting the spring, the position of the scraping plate can be controlled, and by setting the scraping plate, the surface of the inclined platform can be cleaned.
[0020] In summary:

Specific implementation mode
[0028] Referring to Figure 1 As shown, the present utility model provides a technical solution: a drainage device for bridge expansion joints, including two side beams 1. On the side where the two side beams 1 are close to each other, a cross plate 2 is fixedly connected. On the side where the two side beams 1 are close to each other, a fixing plate 3 is fixedly connected. The surface of the fixing plate 3 is sleeved with a filter sleeve plate 4. The surface of the filter sleeve plate 4 is provided with filter holes. The lower surface of the filter sleeve plate 4 is provided with a collection box 7. The lower surface of the collection box 7 is communicated with a drain pipe 8. By providing the fixing plate 3, it can ensure that the filter sleeve plate 4 can move while filtering impurities in rainwater. By providing the collection box 7 and the drain pipe 8, rainwater can be discharged from the expansion joint.
[0029] Next, specifically describe its overall specific settings and functions.
[0030] Referring to Figures 1 - 5As shown, in this embodiment: the upper surface of the collection box 7 is fixedly connected with two second sliders 15, the lower surfaces of the two cross plates 2 are provided with second slide grooves, and the two second sliders 15 are slidably connected to the surface of the second slide groove on the cross plate 2. The second slider 15 slidably connected to the surface of the second slide groove ensures that the collection box 7 can move, and at the same time, the collection box 7 can be connected to the cross plate 2. The upper surface of the filter sleeve 4 is fixedly connected with two inclined platforms 5, and the upper surface of the filter sleeve 4 is fixedly connected with a surrounding plate 6. By setting the surrounding plate 6 and the inclined platform 5, the position of rainwater can be restricted to ensure that rainwater flows down from the filter holes on the filter sleeve 4. The inner walls of the two side beams 1 are provided with first slide grooves, and the surfaces of the first slide grooves on the two side beams 1 are slidably connected with first sliders 14, and the lower surface of the first slider 14 is fixedly connected with the mounting plate 13. By setting the first slider 14, the mounting plate 13 can be connected to the side beam 1 while ensuring that the mounting plate 13 can move.
[0031] The inner wall of the mounting plate 13 is fixedly connected with a sleeve 12, and the inner wall of the sleeve 12 is slidably connected with a slide bar 10. By setting the mounting plate 13, the installation of the sleeve 12 can be completed, and the slide bar 10 slidably connected to the inner wall of the sleeve 12 can move. The end of the slide bar 10 away from the ramp 5 is fixedly connected with a spring 11, and the other end of the spring 11 is fixedly connected with the sleeve 12. By setting the spring 11, a stable connection between the slide bar 10 and the sleeve 12 can be ensured, and by setting the spring 11, the position of the slide bar 10 can be limited. The end of the slide bar 10 away from the spring 11 is fixedly connected with a scraper 9, and the scraper 9 fits tightly with the ramp 5. By setting the spring 11, the position of the scraper 9 can be controlled, and by setting the scraper 9, the surface of the ramp 5 can be cleaned.
[0032] Working principle: when the bridge expands and contracts due to heat, the filter sleeve 4 slides on the surface of the fixed plate 3 and the collection box 7 slides on the surface of the second slide groove on the cross plate 2. When rainwater falls through the two side beams 1, under the restriction of the inclined platform 5 and the enclosure 6, the rainwater enters the collection box 7 through the filter holes on the filter sleeve 4, and then is discharged into the drainage ditch through the drain pipe 8. When it is necessary to clean the surface of the filter sleeve 4, the mobile mounting plate 13 drives the sleeve 12 to move. At this time, the sleeve 12 drives the slide rod 10 to make the scraper 9 move on the surface of the inclined platform 5. At the same time, Under the action of the elastic force of the spring 11, the scraper 9 can be tightly attached to the surface of the ramp 5. After cleaning is completed, the mobile mounting plate 13 drives the first slider 14 to slide on the surface of the first slide groove on the side beam 1 to retract the scraper 9. By setting the filter sleeve 4, the enclosure 6, the collecting box 7 and the drain pipe 8, the rainwater in the expansion joint can be discharged in time, thereby avoiding as much as possible the rainwater in the expansion joint being discharged to both sides along the cross slope of the bridge due to the lack of a warping head. By setting the fixed plate 3 and the second slider 15, the shrinkage effect of the shrinkage joint can be avoided.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.
