[0023] For this specific implementation manner, it further includes a sedimentation tank 101. The horizontal flow sedimentation tank 101 refers to a water treatment structure in which the raw water added with a coagulant flows horizontally from the inlet to the outlet in a rectangular tank, and the flocs are removed by sedimentation.

[0024] Among them, the support rod 103 is fixedly connected to the sedimentation tank 101 and is located on one side of the sedimentation tank 101. The scraping motor 104 is fixedly connected to the support rod 103 and is located on one side of the support rod 103. The driving rod 105 is fixedly connected to the output end of the scraping motor 104 and is located on one side of the scraping motor 104. One end of the mounting seat 106 is rotatably connected to the driving rod 105, and the other end is fixedly connected to the sedimentation tank 101 and is located on one side of the driving rod 105. The connecting rod 107 is fixedly connected to the driving rod 105 and is located on one side of the driving rod 105. A plurality of the mounting parts 109 are respectively arranged on one side of the driving rod 105. The support rod 103 is installed on the surface of the sedimentation tank 101, and the scraping motor 104 is installed inside the support rod 103. When scraping the sludge, the output end of the scraping motor 104 drives the driving rod 105 to rotate. The rotation of the driving rod 105 will drive the mounting parts 109 to rotate around the driving rod 105 as the center. The mounting parts 109 are supported by the driving rod 105 and are close to the side wall. When rotating, the sludge on the side wall will be scraped by the mounting parts 109, avoiding that when cleaning the sedimentation tank 101, only the sludge at the bottom can be cleaned, and the sludge on the side wall cannot be scraped and cleaned.

[0025] Secondly, the adjusting motor 108 is fixedly connected to the connecting rod 107 and is located on one side of the connecting rod 107. The mounting member 111 is fixedly connected to the output end of the adjusting motor 108 and is located on one side of the adjusting motor 108. The side wall scraping plate 110 is located on one side of the mounting member 111. The mounting member 111 is arranged at the output end of the adjusting motor 108. The output end of the adjusting motor 108 drives the mounting member 111 to rotate. The rotation of the mounting member 111 will adjust the inclination angle of the side wall scraping plate 110. Then, the output end of the scraping motor 104 drives the driving rod 105 to rotate. The rotation of the driving rod 105 will drive the side wall scraping plate 110 to rotate around the driving rod 105 as the center. The side wall scraping plate 110 is supported by the driving rod 105 and is close to the side wall. When rotating, the sludge on the side wall will be scraped by the side wall scraping plate 110.

[0026] Meanwhile, the connecting member 112 is slidably connected to the mounting member 111 and is located on one side of the mounting member 111. The first telescopic rod 113 is fixedly connected to the connecting member 112 and is located on one side of the connecting member 112. The spring 115 is fixedly connected to the first telescopic rod 113 and is located on one side of the first telescopic rod 113. The limiting member 114 is fixedly connected to the spring 115 and is located on one side of the spring 115. The second telescopic rod 116 is slidably connected to the first telescopic rod 113 and is located on one side of the first telescopic rod 113. The sidewall mud scraper 110 can slide on the second telescopic rod 116 and is connected and fixed through a connection with a wider outer part and a narrower inner part. By pressing the limiting member 114, the spring 115 is contracted by the sliding of the limiting member 114, enabling the second telescopic rod 116 to slide within the first telescopic rod 113. After the second telescopic rod 116 slides, the connecting rod 107 is released from the restriction of the mounting member 111, so that the sidewall mud scraper can be removed and replaced. After the replacement is completed, the second telescopic rod 116 is aligned with one end of the connecting rod 107 and inserted. Then, when the first telescopic rod 113 is pulled upward to the continued position, the spring 115 pushes the limiting member 114 outward to restrict the positions of the first telescopic rod 113 and the second telescopic rod 116. At the same time, the connecting member 112 at the top of the first connecting rod 107 will be inserted into the mounting member 111 to complete the restriction of rotation, ensuring the connection of the sidewall mud scraper 110 to the connecting rod 107.

[0027] In addition, the bottom mud scraping rod 117 is fixedly connected to the driving rod 105 and is located on one side of the driving rod 105. The scraper 118 is fixedly connected to the bottom mud scraping rod 117 and is located on one side of the bottom mud scraping rod 117. The mounting portion 109 includes a mounting member 111, and the mounting member 111 is fixedly connected to the output end of the adjusting motor 108 and is located on one side of the adjusting motor 108. When the scraping motor 104 drives the driving rod 105 to rotate, it will clean the sidewall silt. At the same time, the rotation of the driving rod 105 will drive the bottom mud scraping rod 117 to rotate synchronously, and the rotation of the bottom mud scraping rod 117 will drive the scraper 118 to clean the bottom silt.

[0028] When using the present utility model, when scraping the silt, one end of the second telescopic rod 116 is aligned and inserted into the connecting rod 107, and then the first telescopic rod 113 is pulled upward to the extreme position. The connecting piece 112 will be inserted into the mounting piece 111 synchronously, and the spring 115 will pop out toward the limiting piece 114 to clamp the first telescopic rod 113 and the second telescopic rod 116, fixing the side wall sludge scraper 110. The inclination angle of the side wall sludge scraper 110 is adjusted by the adjusting motor 108. Then, the output end of the scraping motor 104 drives the driving rod 105 to rotate. The rotation of the driving rod 105 will drive the side wall sludge scraper 110 to rotate around the driving rod 105 as the center. The side wall sludge scraper 110 is close to the side by the support of the driving rod 105. When rotating, the sludge on the side wall will be scraped by the side wall sludge scraper 110. At the same time, the bottom sludge scraping rod 117 drives the scraper 118 to scrape the bottom sludge during rotation, avoiding that when cleaning the sedimentation tank 101, only the bottom sludge can be cleaned, and the sludge on the side wall cannot be scraped and cleaned.

[0029] The second embodiment of the present application is as follows:

[0030] On the basis of the first embodiment, please refer to Figure 5 , wherein, Figure 5 is a cross-sectional view of the whole of the second embodiment of the present utility model. A sludge scraping device for a horizontal flow sedimentation tank for water treatment provided by the present utility model includes a sludge discharging assembly 201. The sludge discharging assembly 201 includes a sludge discharging pipe 202 and an arc-shaped plate 203.

[0031] For this specific embodiment, the sedimentation tank 101 has a sludge discharging groove 204. The sludge discharging groove 204 is located on one side of the sedimentation tank 101. The sludge discharging pipe 202 is fixedly connected to the sedimentation tank 101 and is located in the sludge discharging groove 204. The arc-shaped plate 203 is fixedly connected to the sedimentation tank 101 and is located on one side of the sedimentation tank 101. The bottom of the sedimentation tank 101 has a sludge discharging groove 204. The sludge on the side wall and the bottom sludge will be pushed into the sludge discharging groove 204 due to the rotation of the scraping motor 104, and then cleaned through the sludge discharging pipe 202.

[0032] When using the present utility model, when scraping silt, one end of the second telescopic rod 116 is aligned and inserted into the connecting rod 107, and then the first telescopic rod 113 is pulled upward to the limit position. The connecting piece 112 will be inserted into the mounting piece 111 synchronously, and the spring 115 will pop out towards the limiting piece 114 to clamp the first telescopic rod 113 and the second telescopic rod 116, fixing the side wall mud scraper 110. The inclination angle of the side wall mud scraper 110 is adjusted by the adjusting motor 108. Then, the output end of the scraping motor 104 drives the driving rod 105 to rotate. The rotation of the driving rod 105 will drive the side wall mud scraper 110 to rotate around the driving rod 105 as the center. The side wall mud scraper 110 is close to the side by the support of the driving rod 105. When rotating, the silt on the side wall will be scraped by the side wall mud scraper 110. At the same time, the bottom mud scraping rod 117 drives the scraper 118 to scrape the bottom silt. After the silt on the side wall of the sedimentation tank 101 is scraped off by the side wall mud scraper 110, the bottom mud scraping rod 117 drives the scraper 118 to scrape the silt and scrape it into the mud discharge groove 204. The outlet of the mud discharge groove 204 is an arc-shaped plate 203 to ensure that the scraper 118 will not be damaged after scraping the silt into the mud discharge groove 204. Then, the silt in the mud discharge groove 204 is pumped out through the mud discharge pipe 202, which is more convenient for cleaning the silt in the sedimentation tank.
