[0020] like Figure 1-4As shown, the utility model proposes a secondary sedimentation tank outlet cofferdam pool wall cleaning device, including a connecting seat 3, a mounting assembly 4 fixed to the bottom of the connecting seat 3 and a brush roller 5 connected to the mounting assembly 4, a mounting shaft 44 is provided at the bottom of the mounting assembly 4, a brush head 54 in the brush roller 5 is rotatably connected to the movable end of the mounting shaft 44, a driving motor 52 in the brush roller 5 is installed on the mounting shaft 44, and the output shaft of the driving motor 52 is connected to the brush head 54 through a transmission assembly 53.
[0021] The connecting base 3 serves as the mounting structure for the cleaning device, and the connecting portion at the bottom of the connecting base 3 serves as the cleaning portion. The mounting assembly 4 is used to mount the brush roller 5. The drive motor 52 rotates the brush head 54 through the transmission assembly 53, thereby cleaning the secondary sedimentation tank effluent cofferdam wall via the brush head 54. The bottom of the drive motor 52 is fixedly connected to a mounting base 51, which is then fixed to the mounting shaft 44.
[0022] The connecting seat 3 is used to install the cleaning device at the bottom of the scraper bridge 1. After the scraper bridge 1 is started, the scraper bridge 1 rotates around the secondary sedimentation tank and drives the cleaning device to rotate around the outlet cofferdam. The drive motor 52 is started synchronously, and the drive motor 52 drives the brush head 54 to rotate through the transmission assembly 53. The brush head 54 brushes the pool wall of the outlet cofferdam during the rotation process. Since there is water in the outlet cofferdam, dry brushing will not occur.
[0023] like Figure 2 As shown, in order to enable the brush rollers 5 to be attached to the side walls of the water outlet cofferdam and ensure the quality of brushing, the brush rollers 5 are distributed on both sides of the bottom of the mounting assembly 4. The top end of the mounting shaft 44 is vertically fixedly connected to a connecting shaft 41, which is horizontally rotatably connected to the mounting assembly 4. The mounting assembly 4 is also provided with a connecting block 42. A spring 43 is provided between the connecting block 42 and the connecting shaft 41, and the two brush rollers 5 are pulled apart by the spring 43.
[0024] Since the outlet cofferdam of the secondary sedimentation tank cannot be guaranteed to be a standard ring during construction, some areas of the outlet cofferdam are convex or concave; the two brush rollers 5 are in an eight-shape, and the brush rollers 5 are pulled outward by the spring 43, so that the brush rollers 5 can be tightly attached to the wall of the outlet cofferdam. When brushing the wall of the outlet cofferdam, the brush rollers 5 can always maintain a state of being in contact with the wall of the outlet cofferdam.
[0025] A connecting piece is further provided on the outer side wall of the connecting shaft 41 , and the connecting piece is used for fixing one end of the spring 43 .
[0026] like Figure 2As shown, in order to improve the stability of the mounting shaft 44 , an arc-shaped guide groove 46 is provided at the bottom of the mounting assembly 4 , and the guide groove 46 is coaxially arranged with the connecting shaft 41 . A roller 45 is vertically provided on the mounting shaft 44 and is located in the guide groove 46 .
[0027] By connecting the roller 45 to the mounting shaft 44 , the rotation axis of the roller 45 is arranged perpendicular to the mounting shaft 44 , and the roller 45 is supported by the guide groove 46 , thereby achieving support for the mounting shaft 44 .
[0028] As a preferred embodiment of the present invention, the roller 45 is rotatably mounted, and its outer diameter is equal to the width of the guide groove 46. When the mounting shaft 44 rotates about the connecting shaft 41, the roller 45 moves along the guide groove 46. The rotation of the roller 45 converts sliding friction into rolling friction, allowing the connecting shaft 41 to rotate more smoothly.
[0029] like Figure 2 and Figure 3 As shown. The outer diameter of the movable end of the mounting shaft 44 is larger than the outer diameter of the fixed end. The movable end of the mounting shaft 44 is coaxially provided with a mounting groove, and a mounting bearing 47 is disposed in the mounting groove. The brush roller 5 is rotatably connected to the mounting bearing 47. By providing the mounting groove at the movable end of the mounting shaft 44, the brush roller 5 is coaxially rotatably connected to the mounting shaft 44 using the mounting bearing 47.
[0030] like Figure 1 and Figure 4 As shown, in order to achieve stable installation of the cleaning device, the connecting seat 3 includes a bottom plate and connecting strips vertically fixedly connected to both sides of the bottom plate, and connecting holes are equidistantly arranged on the connecting strips.
[0031] like Figure 1 As shown, the cleaning device is mounted on a scraper bridge 1. A fixing plate 2 is vertically fixed to the sidewall of the scraper bridge 1. The bottom plate is the same width as the scraper bridge 1. The connecting strip is attached to the fixing plate 2, which has threaded holes that match the holes on the connecting strip. The cleaning device is attached to the scraper bridge 1, and the water outlet cofferdam wall is cleaned synchronously with the rotation of the scraper bridge 1.
