Description

Technical Field

[0001] This utility model relates to the field of bridge maintenance, and in particular to a device for cleaning bridge drainage holes. Background Technology

[0002] As part of a bridge, bridge drainage holes can drain water from the bridge surface in a timely manner. However, as the usage time increases, passing vehicles can bring sand, gravel, mud, leaves, branches and other debris onto the bridge surface, which can easily cause blockages in the drainage holes, leading to problems such as water accumulation on the bridge. Therefore, it is necessary to periodically dredge and maintain the bridge drainage holes.

[0003] A Chinese patent website (patent publication number CN223269106U) discloses a device for dredging and maintaining bridge drainage holes, including a movable plate. A bracket is fixed to the top of the movable plate, and a first motor is installed on the top of the bracket. A lead screw is connected to the output end of the first motor. A threaded sleeve is threaded to the outer wall of the lead screw. A rotating disk is fixedly connected to the bottom end of the threaded sleeve. A vertical rod is rotatably connected to the bottom end of the rotating disk. A hole corresponding to the vertical rod is opened in the middle of the movable plate, and a rotating column is installed at the bottom end of the vertical rod.

[0004] The aforementioned drainage hole dredging and maintenance device enables rapid cleaning of drainage holes by mounting cleaning brushes and other components on a movable plate structure, improving the efficiency of traditional manual cleaning. However, when cleaning drainage holes and pipes inside bridges, the movable plate structure has large dimensions on both sides, and most of the drainage holes on bridges are located at the edges on both sides of the bridge. This restricts the movement of the movable plate, and the cleaning brush in the center cannot be aligned with the drainage holes below, thus limiting the application scenarios of this type of dredging device.

A drive motor 110 is axially connected to the top of the threaded shaft 109. A sliding frame 111 is fixed to the bottom surface of the drive motor 110, and sliding grooves 112 are opened on both sides of the outer wall of the sliding frame 111. A guide wheel 113 is embedded in and axially connected to the inner wall of the sliding groove 112. To provide this drain hole cleaning device for rapid and convenient cleaning of bridge drain hole pipes, such as... Figure 1-3 As shown, this drain hole cleaning device adopts a vertical structure housing 101 design, which houses the drive structure of the cleaning brush head 2. Together with the support frame 104 and pulley 105 on both sides of the bottom, it provides stability and mobility during use. The overall footprint is smaller and lighter. With the handle 103, it is easy to move. It can quickly clean the drain holes and drain pipe inner walls on both sides of the bridge. It has a wide range of applications and is easy to operate. When cleaning the drain hole and drain pipe, the above-mentioned device can work with the drive motor 110 to drive the threaded shaft 109 to descend along the threaded sleeve 108, so that the sliding frame 111 mounted on the drive motor 110 descends stably along the equipment cavity 106, providing transmission stability. The cleaning brush head 2 fixed at the bottom of the threaded shaft 109 will descend with the thread, rotating and brushing the drain hole or the inner wall of the pipe while cleaning, thus improving cleaning efficiency.

[0016] like Figure 4 As shown, the cleaning brush head 2 includes a brush head frame 201, and a threaded shaft 109 is fixed at the center of the top surface of the brush head frame 201. Bolts 202 are passed through the top surface of the brush head frame 201.

To maintain structural stability during the cleaning process and ensure replaceability for later maintenance, such as Figure 4 As shown, the brush head frame 201 of this drain hole cleaning device is connected to the brush cylinder 205 through the bottom insert 203, and the surrounding limiting strips 204 keep the angle stable after insertion. At the same time, it is reinforced by bolts 202 to maintain a stable cleaning effect on the drain hole and the inner wall of the drain pipe. The detachable structure design makes it easier to replace and use, and there is no need to clean the brush 206 during operation.

[0017] In summary, when using this drain hole cleaning device, the user first holds the handle 103, and uses the handle 103 to drive the entire outer shell 101 to move along the pulley 105 as a support point. By driving the pulley 105 at the bottom of the outer shell 101, the bottom of the device is aligned with the drain hole on the edge of the bridge. At this time, the cleaning brush head 2 at the bottom is also aligned with the drain hole. Then, the motor control panel 102 drives the drive motor 110 to operate, and the drive motor 110 drives the threaded shaft 109 to rotate. The rotating threaded shaft 109 is connected to the threaded sleeve 108, and the cleaning brush head 2 mounted at the bottom is inserted into the drain hole and the inner wall of the drain pipe while rotating, and is simultaneously rotated and lowered for cleaning.

[0018] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
