[0004] When the above-mentioned prior art is in use, it mainly utilizes the filter baffle and the filter plate to cooperate with each other to filter the accumulated water in the tunnel, but the sewage treatment effect is limited, and only a single filtering treatment can be performed. It is inconvenient to purify the odor in the accumulated water, resulting in a poor working environment during the drainage process. In addition, during the sewage filtration process, the filter plate is easily blocked by impurities, and the anti-blocking effect is poor, which in turn affects the filtering effect and filtering efficiency of the filter plate, and then affects the smooth filtration and drainage. Therefore, corresponding improvements are needed. Utility Model Content

One end of the moving shaft extends to the interior of the drainage box, one end of the linkage shaft is sleeved with the first crushing roller, one end of the rotating shaft is sleeved with a one-way circulation mechanism, and the one-way circulation mechanism and the first crushing roller are meshed with each other, and triangular teeth are evenly connected on the inner wall of the drainage box on one side of the first crushing roller and the one-way circulation mechanism, the top of the drainage box is connected with a pushing frame, and the pushing frame is evenly connected with anti-slip protrusions of rubber material, and a purification component is arranged at the bottom end of the drainage box, the purification component includes a filter plate connected to the interior of the drainage box, and one end of the filter plate is movably connected to the inner wall of the drainage box through a hinge shaft, a knocking component is arranged below the filter plate, and the interior of the drainage box below the knocking component is connected with a purification frame, and the interior of the purification frame is evenly connected with support columns, and the support columns are evenly filled with quartz stone particles, the knocking component includes a rotating block connected to the interior of the drainage box, and one end of the rotating block is penetrated and connected with the support shaft, and the other end of the rotating block is fixedly connected with the knocking block, and a diversion component is arranged at the top of the drainage box.

[0007] When using a tunnel drainage device that can prevent clogging according to the technical solution, by setting up corresponding purification components, the accumulated water in the tunnel can be filtered and purified, and by utilizing the setting of the driving mechanism, the filter plate used for filtering can be knocked to make it vibrate, thereby effectively preventing the filter plate from being blocked too quickly.

[0008] Preferably, the diversion assembly includes a diversion plate connected to the top of the interior of the drainage box, and the diversion plate is evenly provided with diversion holes with rectangular cross-sections, and the interiors of the diversion holes are provided with one-way flow mechanisms, and the one-way flow mechanisms include support frames connected to both sides of the bottom end of the diversion plate, the tops of the support frames are connected with return springs, and one end of the return springs is connected with a blocking block.

[0009] Preferably, the blocking blocks are all made of rubber material, and the width of the blocking blocks matches the width of the diversion holes.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the anti-clogging tunnel drainage device not only has the function of purification and filtration, and can effectively prevent the filter plate from being blocked, but also has the effect of preventing odor from leaking out;

In this process, the servo motor drives the functional main shaft to rotate and makes the special-shaped protrusion rotate synchronously to hit the rotating block to make it turn up and down around the support shaft, so as to knock the filter plate to avoid the blockage of the filter plate, so as to ensure the sufficiency and efficiency of the tunnel water filtration, and further cooperate with the quartz stone particles in the purification frame to absorb the odor in the tunnel sewage to achieve a better purification effect, so as to ensure that the drainage pump can discharge the sewage smoothly and quickly;

[0012] Injecting tunnel sewage into the drainage box and allowing it to flow through the multi-group diversion holes on the diversion plate can achieve diversion of tunnel sewage and avoid damage to the internal components of the drainage box due to the impact of the water flow. In the process of water injection, the water flow impacts the block, causing it to move downward and compress the reset spring. When the water flow ends, the reset spring resets, pushing the block to block the diversion hole, preventing the odor in the tunnel water from flowing out, thereby achieving a better anti-odor effect.
