Description

Technical Field

[0001] The invention relates to the technical field of interception wells, and in particular to an unpowered anti-backflow interception well integrating floating and fixed risers. Background Art

[0002] The interception well is an important facility for diversion and sewage interception. It is mainly used in combined sewer systems or sewage interception projects. On rainy days, it can reasonably distribute the mixed water flow of rainwater and sewage. A part of the relatively clean rainwater can be directly discharged into natural water bodies, and the other part of the polluted water is intercepted and transported to the sewage treatment plant for treatment; its working principle is through the special structure in the well, such as the setting of interception troughs and overflow weirs. When the amount of water is small, all the water can enter the sewage pipe system through the interception pipe; when the amount of water exceeds a certain limit, the excess water (usually rainwater) will cross the overflow weir and be directly discharged into nearby rivers, lakes and other receiving water bodies. In the urban drainage system, the interception well can effectively reduce the direct discharge of untreated sewage into the water body, thereby reducing the pollution of rivers, lakes and other water environments. For example, in the reconstruction of the combined sewer system in some old urban areas, the interception well can initially improve the water quality of the drainage and protect the aquatic ecosystem without large-scale pipe replacement. The interception well is an important part of the rainwater and sewage diversion project. In some areas where initial rainwater pollution is more serious, interception wells can be used to intercept initial rainwater and divert it to the sewage network, while relatively clean rainwater in the middle and late stages can be discharged through overflow. This can reduce the treatment burden of sewage treatment plants to a certain extent, while making full use of rainwater resources.

[0003] There are some problems with the interception well structures currently on the market: Problems of direct discharge of sewage and backflow of river water: In the combined sewer system, the design of the interception well needs to take into account the interception of sewage and backflow of river water. When the elevation of the weir top is set too low, the high water level of sewage may cause sewage to be directly discharged into the river, causing water pollution. On the contrary, when the river water level is higher than the weir top, backflow of river water may occur, resulting in a decrease in sewage concentration. In addition, too high an elevation of the weir top may cause waterlogging in the rainy season; Limitations of electric drive: In order to prevent river water from backflowing, existing interception wells generally use electric-driven interception devices. However, this electric-driven interception method has problems such as high equipment failure rate, high maintenance frequency, and the need for regular replacement of components; Existing interception well technology faces many challenges in design and operation, including direct sewage discharge, river water backflow, garbage blockage, baffle weir deformation, electric drive limitations, discharge design issues, and sewage treatment challenges. These problems limit the performance and efficiency of existing interception well systems. In addition, traditional interception wells have problems such as easy clogging of grid plates and relatively stable cleaning of suspended solids. In order to solve the above problems, the present invention proposes an unpowered anti-backflow interception well integrating floating and fixed risers. Summary of the invention

[0036] Working principle: When the present invention is in use, the unpowered anti-backflow interception well with integrated floating and fixed risers is used during the following process: 1. In dry weather or when sewage is at high water level: Sewage interception: The outlet elevations of the large-diameter main drainage riser 4 and the small-diameter secondary drainage riser 5 are both higher than the river water level and the pipe network water level; at this time, the sewage is intercepted to the sewage treatment plant through the sewage interception pipe 15 to prevent the sewage from being directly discharged into the river; Locking the floating lifting and moving pipe 7: If the water level of the sewage pipe network is higher than the water level of the river, the handle 1410 and the buckle 1411 are unlocked by flipping, and then the handle 1410 and the pull rod 144 are pulled to pull the outer hexagonal rod 142 out of the inner hexagonal sleeve 141, and the second pull rope 143 is pulled. The lock buckle 145 at the end of the second pull rope 143 is locked above the lifting rope 146. During the pulling process of the second pull rope 143, the lifting and moving pipe in the interception well is locked by the lifting rope 146. 7 is lifted up, and during the process, the T-shaped sliding bar 901 moves up along the T-shaped sliding groove 903. When the slot 105 on the bottom end of the T-shaped sliding bar 901 moves to the side of the insertion rod 104, the moving block 103 and the insertion rod 104 are moved and popped out under the elastic action of the first spring 102, so that the end of the insertion rod 104 is inserted into the inside of the slot 105, thereby locking the lifting and moving pipe 7 at the highest upward position, fixing the outlet elevation of the lifting and moving pipe 7, and ensuring that sewage will not overflow into the river.

[0037] 2. When it rains lightly or the river water level is low: Rainwater discharge: When the outlet water level of the small-diameter auxiliary drainage riser 5 is lower than the water level of the pipe network, the rainwater is directly discharged into the river through the small-diameter auxiliary drainage riser 5, which can prevent rainwater from entering the sewage system, reduce the amount of rainwater in the sewage system, and maintain the sewage concentration; The floating riser is stationary: the lifting and moving pipe 7 is kept at the lowest position and does not affect the discharge of rainwater.

[0038] 3. In case of heavy rain or rainstorm: Rapid drainage: When the water level of the pipe network is higher than the outlet water level of the large-diameter main drainage riser 4, rainwater is discharged into the river through the large-diameter main drainage riser 4 and the small-diameter auxiliary drainage riser 5 at the same time to quickly drain the ground water and avoid waterlogging; Floating riser: The floating lifting and moving pipe 7 ensures that rainwater can be discharged smoothly.

[0039] 4. When the river water level rises: Floating riser lifting: As the water level in the river rises, the buoyancy of the floating plate 8 increases, so that the outlet of the lifting and moving pipe 7 is lifted to keep the outlet elevation higher than the river water level to prevent river water from flowing back; Automatic adjustment: The lifting of the floating lifting moving tube 7 is carried out automatically without external power or manual intervention.

[0040] 5. When the river water level drops: Floating riser lowering: When the water level in the river drops, the buoyancy of the floating plate 8 decreases, and the floating lifting pipe 7 is lowered accordingly to increase the drainage water level of rainwater and ensure that rainwater can be effectively discharged; Automatic adjustment: The lowering of the floating lifting moving pipe 7 is also carried out automatically, maintaining the adaptability of the system under different water levels.

[0041] 6. System maintenance and inspection: Regular inspection: Regularly inspect all parts of the interception well to ensure that they are working properly and clean up garbage and debris in time; Check the floating riser: Check the floating riser and sliding system to ensure that they can slide freely when the water level changes and there is no binding; Check the locking system: Check the locking system to ensure that it can reliably fix the position of the floating riser when necessary.

[0042] The intercepting well can be inspected and maintained inside the intercepting well through the inspection step opening 11. During the use of the intercepting well, the manhole cover 12 is covered on the top of the inspection step opening 11. During the covering process of the manhole cover 12 structure, the manhole cover 12 is first placed in the inspection step opening 11, so that the latch rods 1413 on both sides of the manhole cover 12 are aligned with the latch holes 1417 on both sides of the inspection step opening 11, and then the pull handle 1410 and the pull rod 144 drive the outer hexagonal rod 142 to rotate, thereby driving the inner hexagonal sleeve 141 and the upper cam 1416 to rotate, and the cam 1416 rotates to push out the latch rods 1413 on both sides. During the process, the limit blocks 1414 on the latch rods 1413 are aligned with the second The spring 1415 is squeezed and elastically deformed, and the latch rod 1413 is pushed out from the insertion hole 1412 and inserted into the latch hole 1417, and then the pull handle 1410 is released. Under the action of the torsion spring 149, the rotating shaft 148 and the pull handle 1410 are driven to reset and flip, so that the end of the pull handle 1410 is engaged with the buckle 1411 of the step groove 13, and the rotation of the pull handle 1410, the pull rod 144, the outer hexagonal rod 142, the inner hexagonal sleeve 141 and the cam 1416 is braked, so that the latch rod 1413 is pushed out and fixed, and the manhole cover 12 on the inspection step opening 11 is placed and fixed. In the later process of opening the manhole cover 12, the opposite can be done, which is more convenient;When the lifting and moving tube 7 is moved upward to the highest position, the engagement between the pull handle 1410 and the buckle 1411 can be turned over to release the engagement, and then the pull handle 1410 and the pull rod 144 are pulled to pull the outer hexagonal rod 142 out of the inner hexagonal sleeve 141, and the second pull rope 143 is pulled, and the lock buckle 145 at the end of the second pull rope 143 is locked above the lifting rope 146. During the pulling process of the second pull rope 143, the lifting and moving tube 7 in the intercepting well is lifted up by the lifting rope 146, and the lifting and moving tube 7 is moved to the highest position mode. The floating objects are intercepted by the grid plate 6, and the intercepted and filtered sewage is discharged through the outlet pipe 2. The discharged sewage impacts the impeller 196, which drives the installation shaft 195 and the first bevel gear 197 to rotate, and the transmission shaft 198 and the half gear 1910 are driven to rotate under the transmission cooperation of the first bevel gear 197 and the second bevel gear 199. When the half gear 1910 and the rack 1911 are meshed or not meshed, the reciprocating transmission will drive the grille plate 6 to perform lifting and vibration under the cooperation of the slider 191 and the slide slot 192. During the process, the third spring 193 is compressed to play the role of supporting the grille plate 6 for vibration. The reciprocating vibration of the grille plate 6 effectively avoids the problem of floating objects blocking the grille plate 6, which is conducive to the stable operation of the interception well. In the later cleaning process of the grille plate 6, the well cover 12 can be opened, and the lock 145 is connected to the hook 1912. The worker pulls the handle 1410 and the pull rod 144 to pull the outer hexagonal rod 142 out of the inner hexagonal sleeve 141, and pulls the second pull rope 143. The second pull rope 143 is used to lift the grille plate 6 and the floating objects through the lock 145 and the hook 1912. The worker can clean the floating objects above the grille plate 6 by checking the step opening 11, and it is more convenient to clean without climbing down the well. ;
