[0002] The secondary sedimentation tank is one of the most important and widely used structures in sewage treatment. The secondary sedimentation tank is usually set after the biological treatment structure. In the activated sludge process, it is used to precipitate and separate the activated sludge and provide sludge return. In the biofilm treatment process, it is used to precipitate and remove the biofilm separated by the biofilm method. In the activated sludge process, the working effect of the secondary sedimentation tank will directly affect the quality of the return sludge, and then affect the effluent quality of the system.

[0003] During the operation of the secondary sedimentation tank, green algae will form on the inner and outer walls of the effluent weir. If not cleaned in time, it will affect the treatment effect of the secondary sedimentation tank and the effluent water quality. The daily cleaning of green algae, slag and other debris on the walls and edges of the secondary sedimentation tank requires manual scrubbing by operation and maintenance personnel. Although manual cleaning is performed every day, green algae and other debris are generated quickly, the labor cost is high and there are safety hazards.

[0030] In the figure, two mounting frames 3 are vertically fixed on the truss 1; the upper and lower horizontal slide rails 4 are symmetrically fixed on the mounting frames 3; the sliding bracket 5 is movably installed between the upper and lower horizontal slide rails 4; the motor 6 and the transmission shaft 7 are both fixedly connected to the sliding bracket 5, and the rotating shaft of the motor 6 drives the transmission shaft 7 to rotate through the transmission assembly 8; the cleaning brush head 9 is detachably installed at the bottom of the transmission shaft 7; the spring frame 10 is vertically fixed on the truss 1 and is located on the inner side of the mounting frame 3; a spring 11 is connected between the spring frame 10 and the sliding bracket 5, or between the sliding bracket 5 and the roller seat 101.

[0031] In the figure, the sliding bracket 5 includes a Japanese-shaped frame 501, and a plurality of pulleys 502 are installed on the upper and lower sides of the frame 501. Two bearing seats 503 for installing the transmission shaft 7 are vertically arranged on the front of the frame 501. The first connecting seat 504 for connecting the spring 11 is arranged on both sides of the frame 501. The second connecting seat 1001 for connecting the spring 11 is arranged on the spring frame 10. The third connecting seat 103 for connecting the spring 11 is arranged on the inner side of the roller seat 101.

[0032] In actual operation, when the inner wall of the water weir 2 needs to be cleaned, a spring 11 is installed between the second connection seat 1001 and the first connection seat 504 on the left side. At this time, under the action of the elastic force, the cleaning brush head 9 is closely attached to the inner wall of the water weir 2. When the outer wall of the water weir 2 needs to be cleaned, a spring 11 is installed between the first connection seat 504 on the right side and the third connection seat 103. At this time, under the action of the elastic force, the cleaning brush head 9 is closely attached to the outer wall of the water weir 2.

[0033] In the figure, the transmission assembly 8 includes a driving wheel 801, a transmission wheel 802 and a belt 803, wherein: the driving wheel 801 is installed on the rotating shaft of the motor 6, the transmission wheel 802 is installed on the top of the transmission shaft 7, and the belt 803 is sleeved on the driving wheel 801 and the transmission shaft 7.

[0034] In the figure, the cleaning brush head 9 is composed of a central tube 901 and an outer brush 902, and the cleaning brush head 9 is used to clean the inner wall and the outer wall of the water outlet weir 2.
