[0019] Example
[0020] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.
[0021] like Figure 1-3 As shown, a rainwater and sewage diversion reconstruction structure for old roads includes a rainwater and sewage diversion pool 1, a water inlet pipe 2 is arranged at one end of the rainwater and sewage diversion pool 1, and a rainwater pipe 3 and a sewage pipe 4 are symmetrically arranged at the other end. A blocking plate 9 is arranged at the pipe openings of the rainwater pipe 3 and the sewage pipe 4 inside the rainwater and sewage diversion pool 1, and the blocking plate 9 is connected to a driving mechanism. The driving mechanism includes a first driving motor 5 arranged on one side of the rainwater and sewage diversion pool 1, and the output shaft of the first driving motor 5 passes through the side wall of the rainwater and sewage diversion pool 1 and is connected to a screw 6, and the free end of the screw 6 is rotatably connected to the inner wall of the rainwater and sewage diversion pool 1. A filter plate 10 is arranged inside the sewage pipe 4, and a crushing mechanism is arranged on the side of the filter plate 10 close to the blocking plate 9. The crushing mechanism includes a second drive motor 11 arranged at the top of the sewage pipe 4. The output shaft of the second drive motor 11 is connected to a rotating shaft 12. A plurality of crushing knives 13 are arranged on the rotating shaft 12. The free ends of the crushing knives 13 are close to the filter plate 10 but are spaced apart from the filter plate 10. The filter screen intercepts larger impurities, and then the crushing knives 13 crush the impurities so that they can pass through the filter plate 10. The mesh of the filter screen matches the crushing force of the crushing knives 13.
[0022] The screw rod 6 is provided with a sliding sleeve 7, which is connected to the blocking plate 9 through a connecting plate 8, and the length of the blocking plate 9 is the sum of the distances between the rainwater pipe 3, the sewage pipe 4, and the distances between the rainwater pipe 3 and the sewage pipe 4. The distances from both ends of the blocking plate 9 to the side wall of the rainwater and sewage diversion tank 1 close to it are greater than the diameter of the rainwater pipe 3, and the diameters of the rainwater pipe 3 and the sewage pipe 4 are the same. When one of the rainwater pipe 3 or the sewage pipe 4 is in use, the blocking plate 9 can be moved to one side without blocking the use of the pipe.
[0023] The screw 6, the sliding sleeve 7, the blocking plate 9, the rotating shaft 12 and the crushing knife 13 are all provided with anti-corrosion coatings to prevent the device from being corroded during long-term rain or sewage operations.
[0024] During specific use, the device is installed at the required position, and water enters the rainwater and sewage diversion tank 1 through the water inlet pipe 2. Then, according to actual use needs, the first drive motor 5 is driven, and the screw 6 rotates to drive the sliding sleeve 7 to move, so that the blocking plate 9 blocks the rainwater pipe 3 or the sewage pipe 4. When the sewage pipe 4 discharges sewage, the second drive motor 11 is started to drive the rotating shaft 12 to rotate, so that the crushing knife 13 crushes the impurities, and the crushed debris and sewage enter the sewage treatment plant, preventing the impurities from clogging the pipe.
[0025] Therefore, the utility model adopts an old road rainwater and sewage diversion reconstruction structure of the above-mentioned structure, and adopts a blocking plate to divert rainwater and sewage. The sewage pipe can be blocked during the rainwater diversion process. Conversely, the rainwater pipe can also be blocked during the sewage diversion process. It is safe and reliable, and has a simple driving structure, a low failure rate and easy maintenance.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
