[0018] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0019] Example

[0020] like Figure 1-Figure 3As shown: a sedimentation tank for urban sewage treatment, comprising: a sedimentation tank body 1, a fixed bracket 2 is provided on the top of the sedimentation tank body 1, a sliding plate 3 is provided in the middle of the fixed bracket 2, rotating shafts 4 are rotated at both ends of the sliding plate 3, the rotating shaft 4 is rotatably connected to the fixed bracket 2, a gear 5 is provided at one end of the rotating shaft 4, the gear 5 is rotatably connected to one end of a gear rod 6, and the other end of the gear rod 6 is rotatably connected to a motor 7, a cleaning component 8 is provided on the top of the sliding plate 3, and the cleaning component 8 is slidably connected to the fixed bracket 2. The utility model is fixedly connected to the fixed bracket by the sedimentation tank body, the fixed bracket is fixedly connected to the motor, the motor drives the rotating shaft, and the rotating shaft is rotatably connected to the sliding plate. The sliding plate is composed of a main connecting plate, an auxiliary connecting plate and a positioning plate. The sliding plate can protect the top of the sedimentation tank body and the cleaning component can be fully cleaned at the same time, effectively removing impurities such as fallen leaves, thereby improving the treatment effect of the sedimentation tank.

[0021] It can be understood that: the sliding plate 3 includes a main connecting plate 301, an attached connecting plate 302 and a positioning plate 303, the two ends of the main connecting plate 301 are rotatably connected to the rotating shaft 4, the main connecting plate 301 is rotatably connected to the attached connecting plate 302 on one side, and the other end of the attached connecting plate 302 is rotatably connected to the positioning plate 303, and the positioning plate 303 is fixedly connected to the inner side of the fixed bracket 2. Through the mutual cooperation of the main connecting plate, the attached connecting plate and the positioning plate, the sliding plate can realize the comprehensive cleaning of the top of the sedimentation tank body, effectively remove impurities such as fallen leaves, and improve the treatment effect of the sedimentation tank. The design of the attached connecting plate and the positioning plate makes the sliding plate more stable during the sliding process, can adapt to different working environments and work requirements, and reduces the failure rate. All parts of the sliding plate can be easily disassembled and cleaned, and it is very convenient to maintain. This not only reduces the burden on maintenance personnel, but also reduces maintenance costs.

[0022] It can be understood that: the attached connecting plate 302 is symmetrical about the central axis, and both ends of the attached connecting plate 302 are slidably connected to the fixed bracket 2. When the cleaning system needs to be repaired or upgraded, the staff can easily slide the attached connecting plate from the fixed bracket to conveniently access other parts of the sliding plate. This not only improves the structural stability, maintains smooth sliding, improves cleaning efficiency and facilitates maintenance.

[0023] It can be understood that: the main connecting plate 301 is composed of a threaded sleeve 304 and a connecting plate 305, the threaded sleeve 304 is rotatably connected to the rotating shaft 4, the two ends of the connecting plate 305 are slidably connected to the fixed bracket 2, and a cleaning component 8 is arranged above the main connecting plate 301. The unique design of the main connecting plate consisting of a threaded sleeve and a connecting plate, and the layout of the cleaning component on the top, bring many practical benefits to the new sedimentation tank, including improving sliding stability, enhancing equipment durability, improving cleaning efficiency and facilitating maintenance, etc. These advantages together ensure that the entire cleaning system can operate stably for a long time, and provide strong support for maintaining the cleanliness and treatment effect of the sedimentation tank water quality.

[0024] It can be understood that: the cleaning component 8 includes a sliding plate 801, and a plurality of positioning rods 802 are provided in the middle of the sliding plate 801. The positioning rods 802 are distributed in an array, and one end of the positioning rods 802 is fixedly connected to a scraper 803. A spring 804 is provided above the scraper 803. The array distribution of the positioning rods enables the scraper to maintain a stable posture and uniform force during the sliding process, thereby improving the cleaning effect, and can be adaptively adjusted according to the different shapes and conditions of the sliding plate to ensure that the scraper always maintains close contact with the top of the sedimentation tank, thereby improving the cleaning efficiency.

[0025] It can be understood that: the sliding plate 801 is slidably connected to the fixed bracket 2, the sliding plate 801 is composed of a sliding sleeve 805 and a bearing plate 806, a plurality of positioning rods 802 are arranged in the middle of the bearing plate 806, and a plurality of positioning rods are arranged in the middle of the bearing plate, and these positioning rods are distributed in an array, providing stable support and positioning for the scraper. During the cleaning process, the positioning rods can ensure that the scraper is always in contact with the top of the sedimentation tank with a constant posture and strength, thereby improving the cleaning effect. At the same time, the positioning rods can also absorb and disperse the impact force encountered by the scraper during the cleaning process, protecting the scraper and the sliding plate from damage.

[0026] The working process of the utility model is as follows: before the sedimentation tank is started or the cleaning cycle begins, the sliding plate and the cleaning assembly are in a stationary state, and the top of the sedimentation tank body is sealed, and the cleaning assembly starts working first. The cleaning assembly includes a sliding plate, on which multiple groups of positioning rods and scrapers are arranged. The sliding plate is slidably connected to the fixed bracket through a sliding sleeve, and the bearing plate carries the positioning rods and scrapers. During the sliding process, the scraper slides closely against the top of the sedimentation tank body through the buffering effect of the spring, effectively scraping off impurities such as fallen leaves.

[0027] The connecting plate is symmetrical about the central axis, and the two ends are slidably connected to the fixed bracket, which not only enhances the stability of the sliding plate, but also enables the cleaning assembly to adapt to the different shapes and sizes of the sedimentation tank body to ensure comprehensive cleaning. Then the motor is activated, and the power is transmitted to the rotating shaft through the rotation of the gear rod and gear. In this process, the rotation of the motor is converted into the meshing movement of the gear rod and gear, which in turn drives the rotating shaft to rotate.

[0028] The rotation of the rotating shaft drives the sliding plate to start sliding. The sliding plate is composed of a main connecting plate, an auxiliary connecting plate and a positioning plate, wherein the main connecting plate is rotatably connected to the rotating shaft through a threaded sleeve, and the connecting plate is slidably connected to the fixed bracket at both ends. This design enables the sliding plate to slide stably along the fixed bracket.

[0029] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
