Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment technology, specifically relating to an automatic sewage sweeping vehicle. Background Technology

[0002] Secondary sedimentation tank cleaning primarily addresses the need to remove sludge, suspended solids, and other pollutants in wastewater treatment. Secondary sedimentation tanks are typically a crucial piece of equipment in wastewater treatment plants. Their main function is to further settle suspended solids in wastewater that has undergone initial sedimentation through gravity, achieving higher water quality standards. During this process, due to prolonged deposition and settling, a large amount of sludge accumulates at the bottom of the tank, requiring regular cleaning.

[0003] While existing technologies involve manually cleaning secondary sedimentation tanks using homemade brushes, the cleaning operation requires standing on a moving vehicle, which poses certain safety risks and consumes a significant amount of time. Therefore, those skilled in the art have provided an automatic sewage sweeper to address the problems mentioned in the background section. Utility Model Content

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 , Figure 2 As shown, an automatic sewage sweeper includes a support frame 6. A solar panel 4 is fixedly connected to the top of the support frame 6. A control box 5 is fixedly connected to the middle of the bottom of the inner wall of the support frame 6. The control box includes modules such as a battery, a speed regulator, and a controller. Several dike cleaning devices 1 are arranged on the front and rear sides of the top of the support frame 6. Two auxiliary devices 2 are arranged on the middle of the bottom of the support frame 6. A pool cleaning device 3 is arranged on the rear side of the bottom of the support frame 6. During operation, the device is powered by the battery in the control box 5 through the solar panel 4. The speed regulator is installed in the solar panel 4 to control the speed of the drive wheels 10. The speed difference between the two drive wheels 10 enables the entire device to move forward along the circular wall of the secondary sedimentation tank.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, support plates 9 are fixedly connected to the front positions on both sides of the bottom end of the support frame 6. Third servo motors 8 are fixedly connected to the side walls of the two support plates 9 respectively. The two third servo motors 8 rotate through the support plates 9 and are fixedly fitted with drive wheels 10. Universal wheels 7 are respectively provided on the rear sides of the bottom end of the support frame 6. When the entire device is placed in the secondary sedimentation tank, the drive wheels 10 are made to contact the surface of the cofferdam. The third servo motors 8 drive the drive wheels 10 to rotate, thereby driving the entire device to move.

[0026] like Figure 1 , Figure 4 As shown, an adjustment plate 102 is fixedly connected to the top of the support frame 6. The adjustment plate 102 has multiple slots, which can adjust the position of the equipment and effectively improve the adaptability of the equipment. A connecting rod 103 is fixedly connected to the middle of the top of the adjustment plate 102. A first servo motor 104 is fixedly connected to the other end of the connecting rod 103. A mounting plate 105 is fixedly connected to the output end of the first servo motor 104. First brushes 101 are fixedly connected to both sides of the mounting plate 105. The multiple sets of first brushes 101 at the front end of the support frame 6 can be used to clean the inner and outer walls of the effluent steel ruler in the secondary sedimentation tank.

[0027] like Figure 1 , Figure 6 As shown, a fixed frame 201 is fixedly connected to the bottom of the support frame 6, and a square tube 202 is fixedly connected to the bottom of the fixed frame 201. A limiting groove 206 is opened on the side wall of the square tube 202, and a spring 207 is provided in the middle of the inner wall of the square tube 202. Two sliding rods 203 are slidably connected to the inner wall of the square tube 202. One end of each sliding rod 203 is rotatably connected to an auxiliary wheel 204. A limiting block 205 is fixedly connected to the side wall of the sliding rod 203. The limiting block 205 is slidably connected to the inner wall of the limiting groove 206. After the device is placed in the secondary sedimentation tank, the elastic force of the spring 207 presses the auxiliary wheel 204 against the inner side wall of the tank wall, which allows the device to better adapt to the changes in the width of the tank wall, prevents the trolley from getting stuck, and uses the limiting block 205 to limit the auxiliary wheel 204 and the sliding rod 203 to prevent them from getting stuck, effectively improving the stability of the device when moving.

[0028] like Figure 1 , Figure 5As shown, a positioning frame 301 is fixedly connected to the bottom of the support frame 6, and a mounting frame 305 is fixedly connected to the rear end of the positioning frame 301. A rotating shaft 303 is rotatably connected to the inner wall of the mounting frame 305. Several second brushes 302 are arranged in a circular array on the side wall of the rotating shaft 303. A second servo motor 304 is fixedly connected to the top of the mounting frame 305. The output end of the second servo motor 304 rotates through the top of the mounting frame 305. The second servo motor 304 is fixedly connected to the top of the rotating shaft 303. The second servo motor 304 drives the rotating shaft 303 to rotate, so that the second brushes 302 can clean the inner wall of the secondary sedimentation tank, further expanding the cleaning area and effectively improving the cleaning efficiency.

[0029] It should be noted that, in use, this automatic sewage sweeper is placed entirely into the secondary sedimentation tank, so that the drive wheel 10 contacts the surface of the embankment. The third servo motor 8 drives the drive wheel 10 to rotate, thereby driving the entire device to move. During operation, the device is powered by the battery in the control box 5 through the solar panel 4, and the solar panel 4 is equipped with a speed regulator to control the speed of the drive wheel 10. The speed difference between the two drive wheels 10 allows the entire device to move forward along the circular wall of the secondary sedimentation tank. After the device is placed in the secondary sedimentation tank, the elastic force of the spring 207 presses the auxiliary wheel 204 against the inner wall of the tank, which allows the entire device to better adapt to changes in the width of the tank wall and prevents the vehicle from getting stuck. The multiple sets of first brushes 101 at the front end of the support frame 6 can clean the inner and outer walls of the effluent steel ruler in the secondary sedimentation tank. At the same time, the second servo motor 304 drives the rotating shaft 303 to rotate, so that the second brush 302 can clean the inner wall of the secondary sedimentation tank.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
