[0002] A diversion tunnel-based pollution interception mechanism generally refers to a device installed at or near the entrance of a diversion tunnel to block and remove floating objects, silt and other debris entering a water conservancy project. This type of mechanism is designed to protect water conservancy facilities, prevent debris from clogging waterways and damaging equipment, and reduce pollution to water resources.

[0003] Existing technologies typically use grids or fences installed at the entrance of a diversion tunnel to block most floating debris and sediment. However, this requires manual cleaning and collection of pollutants, which is difficult. Furthermore, the barrier is difficult to remove and maintain, leading to maintenance issues. Therefore, a new sewage interception mechanism based on the diversion tunnel has been proposed to address these issues. Utility Model Content

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] The utility model is based on the sewage interception mechanism of the diversion tunnel, such as Figure 1 As shown, the structure includes a pipe 1, which is the main structure of the entire pollution-blocking mechanism and is responsible for guiding the incoming water flow. A grille 2 is fixedly connected to the water inlet end of the pipe 1. The grille 2 is used to block large floating particles and prevent pollutants from being carried away by the water flow. A bottom plate 3 is fixedly connected to the bottom of the water inlet end of the pipe 1, and a fixed plate 10 is fixedly connected to the top of the water inlet end of the pipe 1. A pollution-scraping mechanism is provided between the bottom plate 3 and the fixed plate 10. The bottom plate 3 and the fixed plate 10 provide support and stability for the pollution-scraping mechanism.

[0024] like Figure 2As shown, the scraping mechanism includes a first support plate 4 fixed to the bottom plate 3 and flush with the ends of the pipe 1 wall; a first fixed rod 5 is fixed between the two first support plates 4, and the outer walls of the first fixed rod 5 are respectively connected to the first pulley 6 in rotation close to the first support plate 4; second support plates 12 are fixed on both sides of the fixed plate 10 at positions corresponding to the first support plates 4, and a second fixed rod 21 is rotatably connected between the second support plates 12, and a second pulley 22 is fixed on the outer wall of the second fixed rod 21 at positions corresponding to the first pulley 6; a belt 7 is connected between the first pulley 6 and the second pulley 22 at corresponding positions, and the two belts 7 are fixed to a connecting rod 8 on the side close to the grille 2, and a plurality of scraping strips 9 are fixed to the connecting rod 8, and the scraping strips 9 are in contact with the inside of the grille 2; a motor 13 is fixed to the outside of one of the second support plates 12, and the driving end of the motor 13 is connected to the second fixed rod 21. A collection groove 11 is opened at the end of the fixed plate 10 close to the grille 2, and the collection groove 11 is an L-shaped through groove. The scraper 9 is driven by the motor 13 to reciprocate and scrape off debris in the grille 2 at different heights. After it is lifted to the top, it rotates up and down, so that floating objects fall into the collection tank 11 due to the inertial force, so that workers can clean the floating objects on the shore and avoid going into the water to clean the grille 2.

[0025] A through slot 23 perpendicular to the water flow direction is also provided on the top of the pipe 1. A filter plate 14 is slidably connected to the pipe 1 through the through slot 23. A pull ring 18 is fixed to the top of the filter plate 14. The filter plate 14 is used to further filter and block fine debris and sediment. Figure 3 As shown, a slot 15 corresponding to the through slot 23 is provided at the bottom of the pipe 1. A plurality of first springs 16 are fixed to the bottom of the slot 15. A connecting plate 17 is fixed to the free ends of the plurality of first springs 16. The connecting plate 17 is slidably connected to the slot 15. The filter plate 14 is fixed to the slot 15, and the bottom of the filter plate 14 contacts the top of the connecting plate 17. In order to facilitate the removal and fixing of the filter plate 14, a clamping rod 19 is slidably connected to the filter plate 14 in the top wall of the pipe 1, as shown in FIG. Figure 4 As shown, a second spring 20 is fixed to the end of the clamping rod 19 away from the filter plate 14, and the other end of the second spring 20 is fixed to the interior of the top wall of the pipe 1. A groove is defined on the exterior of the top wall of the pipe 1 where it meets the second spring 20. A shift block 24 is fixed to the clamping rod 19 near the second spring 20, and the shift block 24 slides within the groove. A through hole is defined at the location where the filter plate 14 and the clamping rod 19 engage. The clamping rod 19 slides through the filter plate 14 to secure the filter plate 14, restricting its vertical movement.

[0026] The working principle of the sewage interception mechanism based on the diversion tunnel of the utility model is as follows:

[0027] Turn on the switch of the motor 13, and the second fixed 21 is driven to rotate by the driving end of the motor 13, which drives the two second pulleys 22 to rotate, and further drives the belt 7 to make relative movement outside the pulley 6. At the same time, the reciprocating lifting and lowering motion of the belt 7 drives the connecting rod 8 and multiple scraping strips 9 to make reciprocating lifting and lowering motions, continuously scraping off the pollutants blocked by the scraping strips 9. When the pollutants move to the top, the rotation direction of the connecting rod 8 changes the up and down direction of the scraping strips 9 when it reaches the highest point, so that the debris falls into the collection tank 11 through the inertia of gravity and is scraped by the scraping strips 9, which is convenient for the staff to collect and clean. Timely and effective cleaning can prevent the sewage grille 2 from weakening its isolation effect due to blockage, thereby reducing environmental pollution.

[0028] Secondly, by moving the shift block 24, the clamping rod 19 is driven to slide inside the top wall of the pipe 1, compressing the second spring 20 on the rear side, and then the filter plate 14 is slid inside the pipe 1 through the pull ring 18, and the filter plate 14 is slid into the inside of the card slot 15, contacting with the top of the card slot 15, squeezing the multiple first springs 16 on the lower side, and then releasing the shift block 24. The reaction force of the second spring 20 pushes the clamping rod 19 to slide inside the filter plate 14, completing the clamping and fixing of the filter plate 14 to the pipe 1. By adding a filter plate 14 that is easy to disassemble and install, the dirt isolation effect is improved, and the staff can easily remove the filter plate 14 for cleaning or maintenance, reducing costs.
