[0030] like Figures 1 to 5As shown, a municipal engineering drainage structure includes: a fixed block 1, a through hole 104 is opened inside the fixed block 1, and the through hole 104 passes through the fixed block 1; a cover plate 2 is arranged inside the fixed block 1 and is used to filter debris; a sealing component 4 is arranged inside the fixed block 1 and is used to control the flow direction of rainwater; a guide component 3 is arranged outside the sealing component 4 and is used to guide the sealing component 4. Specifically, during the drainage process, the rainwater on the top of the cover plate 2 is discharged into the bottom of the fixed block 1 through the cooperation of the sealing component 4 and the cover plate 2. When the rainwater at the bottom of the fixed block 1 flows back, the backflowing rainwater is blocked through the cooperation of the sealing component 4 and the cover plate 2 to avoid waterlogging caused by the backflow of rainwater during use.

[0031] like Figures 1 to 5 As shown, a mounting groove 101 is provided at the end of the through hole 104, a sliding groove 103 is provided on the inner wall of the through hole 104, and there are multiple sliding grooves 103. A connecting plate 102 is also provided on the outside of the fixed block 1. Specifically, the fixed block 1 is installed at the water inlet, and the connection between the fixed block 1 and the water inlet is further increased by the connecting plate 102 to prevent the fixed block 1 from moving when rainwater flows back, thereby ensuring stability during use.

[0032] like Figures 1 to 5 As shown, the cover plate 2 is adapted to the mounting groove 101, and a filter hole is provided inside the cover plate 2, and there are multiple filter holes. A fixing pipe 201 is provided on one side of the cover plate 2 relative to the fixing block 1, and the fixing pipe 201 is located at the center of the cover plate 2. A drainage hole 202 is provided on one end of the fixing pipe 201 relative to the cover plate 2, and there are multiple drainage holes 202. Specifically, when the cover plate 2 is installed, the cover plate 2 is positioned by the mounting groove 101 to avoid a gap between the cover plate 2 and the fixing block 1 during use, which causes debris to enter the fixing block 1 through the gap and accumulate and cause blockage. The filter holes inside the cover plate 2 filter the debris in the rainwater to avoid the debris entering the fixing block 1 and accumulating and causing blockage. The cover plate 2 and the fixing block 1 are connected by bolts to ensure the stability of the position of the cover plate 2 relative to the fixing block 1 during use, and to avoid pushing the cover plate 2 to move relative to the fixing block 1 when rainwater flows back.

[0033] like Figures 1 to 5As shown, the sealing assembly 4 includes a sliding block 401, which slides inside the through hole 104. The sliding block 401 is provided with a groove 402 on one side relative to the cover plate 2. A sliding tube 403 is arranged inside the groove 402, and the sliding tube 403 is sleeved on the outside of the drainage hole 202. A water outlet 404 is opened at the center of the sliding block 401, and the water outlet 404 runs through the sliding block 401. A floating block 405 is arranged on the outside of the sliding block 401. Specifically, the density of the floating block 405 and the sliding block 401 is less than the density of water, so that when the water level at the bottom of the fixed block 1 rises, the floating block 405 and the sliding block 401 can always float on the water surface, and the sum of the buoyancy of the floating block 405 and the sliding block 401 is greater than the weight of the water collected in the groove 402, ensuring that the sliding tube 403 can be driven to move when the water level at the bottom of the fixed block 1 rises. The sliding block 401 has the same shape as the through hole 104, and the sliding tube 403 is sleeved on the outside of the fixed tube 201, and The top of the sliding tube 403 is against the cover plate 2. When rainwater needs to be discharged, the rainwater first enters the groove 402 through the filtration of the cover plate 2 for collection. During the collection process, the sliding block 401 pushes the sliding block 401 downward under the action of the weight of the rainwater. While the sliding block 401 moves, it drives the sliding tube 403 to separate from the cover plate 2. At the same time, the sliding tube 403 leaks the drainage hole 202, so that the rainwater in the groove 402 can be discharged through the drainage hole 202 and the water outlet hole 404. When the water level at the bottom of the fixed block 1 gradually rises and backflow occurs, since the density of the floating block 405 is less than that of the rainwater, the sliding block 401 is pushed upward by the floating block 405 under the action of the rainwater, so that the top of the sliding tube 403 is against the cover plate 2, and the sliding tube 403 coincides with the drainage hole 202, so that the groove 402 and the drainage hole 202 are blocked, so as to prevent the rainwater at the bottom of the fixed block 1 from backflowing upward and causing waterlogging.

[0034] like Figures 1 to 5As shown, the guide assembly 3 includes a connecting block 301, and there are multiple connecting blocks 301. The connecting blocks 301 are connected to the sliding block 401, and the connecting blocks 301 correspond to the sliding grooves 103. The connecting blocks 301 are provided with guide rods 302 inside, and the guide rods 302 move relative to the connecting blocks 301. The guide rods 302 are connected to the fixed block 1, and the outer side of the guide rods 302 is sleeved with springs 303. Specifically, during the movement of the sliding block 401, the movement direction of the sliding block 401 is guided by the cooperation of the connecting block 301 and the guide rods 302. To ensure the stability of the sliding block 401 during movement, the elastic force of the spring 303 is greater than the gravity of the sliding block 401 and the floating block 405. When the groove 402 collects rainwater, the sliding block 401 compresses the spring 303 downward under the action of rainwater. When the rainwater in the groove 402 evaporates, the spring 303 rebounds. When the spring 303 rebounds, it pushes the top of the sliding tube 403 to contact the cover plate 2, thereby blocking the drainage hole 202 and the groove 402, preventing the odor at the bottom of the fixed block 1 from floating out through the water outlet 404 and the drainage hole 202.

[0035] like Figures 1 to 5 As shown, the interior of the float block 405 is hollow. Specifically, the float block 405 and the sliding block 401 can be connected by means of snaps or bolts. The hollow float block 405 further increases the buoyancy during use, so that when the water level rises, the sliding tube 403 can be controlled to fully fit with the cover plate 2, thereby preventing rainwater from flowing back through the gap.
