[0002] The secondary sedimentation tank plays a crucial role in the sewage treatment process. However, the problem of moss growth on the water outlet cofferdam is very troublesome. Moss is formed by the attachment and growth of moss spores contained in the effluent of the secondary sedimentation tank on the cofferdam under photosynthesis. Moss not only affects the aesthetics, but also its large-scale growth will cause blockages in the water outlet and the on-line monitoring sampling system, affecting the transmission of detection data, and it needs to be cleaned frequently. In the prior art, it is necessary to manually use tools to forcefully remove it. Due to the extremely fast growth rate of moss, it needs to be cleaned every day, which is not only time-consuming and laborious, but also has serious safety hazards and is prone to situations of falling into the tank and drowning. Therefore, there is an urgent need to provide a moss cleaning device for the water outlet cofferdam of a secondary sedimentation tank to replace manual cleaning of moss, reduce labor intensity, and improve cleaning efficiency and safety.

[0027] In the present utility model, unless otherwise clearly specified and defined, terms such as "set", "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] Such as Figure 1As shown in the figure, a moss cleaning device for the effluent cofferdam of a secondary sedimentation tank includes a rotating trestle 2 arranged radially along the secondary sedimentation tank 1. The rotating trestle is a prior art and is a part of the rotating sludge scraper in the secondary sedimentation tank. A roller 12 is rotatably connected to the bottom of the rotating trestle, and the roller is cooperatively connected with a track 102 provided at the upper end of the tank wall 101 of the secondary sedimentation tank. A motor 13 is connected to the roller. One end of the rotating trestle is rotatably installed in the middle of the secondary sedimentation tank, and the other end is driven by a motor to rotate the roller along the track at the upper end of the tank wall. In the present invention, the moss cleaning mechanism is installed on the rotating trestle, and the rotation of the rotating trestle is used to drive it to clean the moss along the effluent cofferdam. There are two groups of moss cleaning mechanisms, symmetrically arranged on both sides of the rotating trestle close to the effluent cofferdam 3. Each group of moss cleaning mechanisms is connected to the rotating trestle through a hanger. Combined with Figure 3 As shown in the figure, the moss cleaning mechanism includes three cleaning components. One group of cleaning components is located directly above the effluent cofferdam, which is convenient for cleaning the top surface of the effluent cofferdam. The other two groups of cleaning components are located inside and outside the effluent cofferdam respectively, and are used to clean the inner wall and outer wall surfaces of the effluent cofferdam respectively. Each group of cleaning components includes a telescopic rod 4, a spring 5 sleeved on the telescopic rod, and a cleaning brush 6 connected to the telescopic rod. The spring is located between the telescopic rod and the cleaning brush. The spring can ensure that the cleaning brush is always in close contact with the effluent cofferdam, improving the cleaning effect and avoiding the situation that the end of the cleaning brush cannot effectively contact the effluent cofferdam due to wear after long-term use.

[0029] Combined with Figures 1 to 3 As shown in the figure, the hanger includes a horizontally arranged T-shaped rod and first connecting rods 7 vertically connected to both ends of the T-shaped rod. The two first connecting rods are located inside and outside the effluent cofferdam respectively, and are respectively connected to the telescopic rods of the cleaning components on the corresponding side. The telescopic rod of the other group of cleaning components is connected to the lower end of the T-shaped rod. The T-shaped rod includes a second connecting rod 8 and a third connecting rod 9. One end of the second connecting rod is connected to the rotating trestle, and the other end is connected to the middle of the third connecting rod. Sleeves 10 are provided at the connection points of the T-shaped rod and the two first connecting rods. Each first connecting rod is slidably connected to the corresponding sleeve up and down. A locking screw 11 is threadedly connected to each sleeve. After tightening the locking screw, the first connecting rod can be fixed to the sleeve. This structural design is convenient for freely adjusting the height of the first connecting rod according to actual needs, thereby adjusting the height of the cleaning brush. The telescopic rod includes a hollow tube 401 and a movable rod 402 with one end disposed inside the hollow tube. The structure is simple and practical, and the movable rod can move freely inside the hollow tube. For the convenience of maintenance, repair and replacement of the telescopic rod, the spring and the cleaning brush, the telescopic rod is threadedly connected to the first connecting rod, the T-shaped rod, and the cleaning brush respectively, which is convenient for disassembly and assembly.

[0030] As Figure 4 and Figure 5As shown in the figure, the cleaning brush includes a fixing plate 602 with a threaded hole 601 in the middle of the upper end, a movable plate 603, and bristles 604 provided at the bottom of the movable plate. One end of the bottom of the fixing plate is provided with a slot 605, and the other end is provided with a stopper 606. The movable plate is slidably connected to the slot. When the bristles are severely worn during long-term use, the movable plate can be removed from the fixing plate for replacement. In the utility model, the fixing plate and the movable plate are movably connected, which can effectively reduce the maintenance cost. The inner wall of the slot is provided with a rubber pad 607, which can enhance the friction between the movable plate and the fixing plate and prevent the movable plate from falling off during the cleaning process.

[0031] The working principle of the utility model is as follows:

[0032] As Figures 1 to 5 shown in the figure, by using the daily work of the rotary sludge scraper in the secondary sedimentation tank 1, the motor 13 drives the roller 12 to realize the circular motion of the rotary trestle 2 along the pool wall 101 of the secondary sedimentation tank 1 and the effluent weir 3. The cleaning brushes 6 of the three cleaning components simultaneously brush the upper surface, inner side wall and outer side wall of the effluent weir 3, effectively removing the moss on its surface, thus replacing the traditional manual cleaning method, saving time and effort, improving the cleaning efficiency and eliminating the drowning risk.

[0033] The above shows and describes the basic principles, main features and advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the utility model.
