[0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the development of highways and urban roads has been very rapid in recent years. As a part of the bridge, bridge drain holes can drain the water on the bridge deck in a timely manner, preventing the formation of water film on the bridge deck, which reduces the bridge deck's anti-skid ability and prevents high-speed vehicles from being unable to brake properly and easily skidding. However, as the bridge is used for a long time, sand, gravel, and other objects brought onto the bridge deck by passing vehicles can easily cause the bridge drain holes to become clogged, leading to problems such as bridge waterlogging. Therefore, bridge drain holes need to be cleared and maintained.

[0003] However, it is generally necessary for staff to manually dredge the drain holes, which is cumbersome to use during the operation, and the cleanliness of manual dredging of the drain holes is poor, which is not conducive to long-term work. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example

[0024] Reference Figure 1-4The top of the lifting post 314 is provided with a screw thread 313, and the bottom of the lifting post 314 is provided with a screw thread 313. The screw thread 313 is threadedly connected to the screw thread 313, and the bottom of the screw thread 313 is fixed with a screw thread 314. The bottom of the screw thread 314 is fixedly connected to a rotating disk 315. The bottom end of the rotating disk 315 is rotatably connected to the vertical rod 215. A hole 214 corresponding to the vertical rod 215 is provided in the middle position of the moving plate 1. A rotating column 217 is installed at the bottom end of the vertical rod 215. Several groups of cleaning brushes 218 are provided on the outer wall of the rotating column 217. By turning on the first motor 312 to drive the screw thread 313 to rotate, the threaded sleeve 314, the rotating disk 315, the vertical rod 215, the rotating column 217 and the cleaning brush 218 are driven downward by the action of the thread to achieve the purpose of automatic vertical lifting. The cleaning brush 218 can clean the inner wall of the bridge drainage hole. A guide rod 317 is fixed to the top of the rotating disk 315. A guide hole 316 is defined within the bracket 311, corresponding to the guide rod 317. The guide hole 316 and the rotating disk 315 provide greater stability. A baffle 318 is fixed to the top of the guide rod 317. The diameter of the baffle 318 is larger than that of the guide hole 316. The baffle 318 prevents the guide rod 317 from disengaging from the guide hole 316, thereby enhancing the stability of the height adjustment of the vertical rod 215. A second motor 320 is installed on the inner wall of the top of the movable plate 1, and a driving gear 321 is connected to the output end of the second motor 320. A driven gear 319 that meshes with the driving gear 321 is fixed to the outer wall of the vertical rod 215. When the driven gear 319 moves to mesh with the driving gear 321, the driving gear 321 is driven to rotate by turning on the second motor 320. The driving gear 321 drives the driven gear 319, the vertical rod 215, the rotating column 217 and the cleaning brush 218 to rotate, which can further enhance the cleaning effect of the inner wall of the drain hole.

[0025] Four sets of moving wheels 211 are installed at the bottom of the moving plate 1, two sets of connecting plates 212 are fixed on the top of the moving plate 1, and fixed rods 213 are fixed on the top of the two sets of connecting plates 212. The moving wheels 211 can support the moving plate 1 to move on the bridge, so as to find the corresponding drainage hole. Pushing the fixed rod 213 can push the moving plate 1 to move, which is more comfortable to use.

[0026] A connecting sleeve 216 is fixed to the top of the rotating column 217, and the bottom end of the vertical rod 215 is inserted into the connecting sleeve 216. The vertical rod 215 and the connecting sleeve 216 are threadedly connected by a bolt 219. By rotating the bolt 219, the connecting sleeve 216 and the vertical rod 215 can be disassembled and assembled, making it convenient for the staff to maintain and clean the rotating column 217 and the cleaning brush 218.

[0027] Working principle: When it needs to be used, push the fixed rod 213 to push the movable plate 1 to move, and correspond the rotating column 217 to the drain hole of the bridge. Turn on the first motor 312 to drive the screw rod 313 to rotate, and under the action of the thread, drive the threaded sleeve 314, the rotating disk 315, the driven gear 319, the vertical rod 215, the rotating column 217 and the cleaning brush 218 to move downward. The guide rod 317 can slide along the inner wall of the guide hole 316, driving the driven gear 319 to correspond to the driving gear 321. After turning on the second motor 320, it drives the driving gear 321 and the driven gear 319 to rotate, and the driven gear 319 drives the vertical rod 215, the rotating column 217 and the cleaning brush 218 to rotate, thereby comprehensively cleaning the drain hole of the bridge.

[0028] When the rotating column 217 needs to be disassembled, the bolt 219 is rotated and the rotating column 217 is then pulled downward, and the connecting sleeve 216 can be disengaged from the bottom of the vertical rod 215, thereby facilitating the removal of the rotating column 217 and facilitating the maintenance or cleaning of the rotating column 217 by the staff.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
