Description

Technical Field

[0001] The present application relates to the technical field of municipal engineering, and in particular to a municipal engineering culvert anti-blocking structure. Background Art

[0002] With the rapid development of cities, urban municipal construction is inseparable from the construction of roads. When building roads, a supporting drainage system must be built. The drainage system is generally a culvert under the road. Sewers connected to the road surface are installed at intervals on the culvert. The sewers are connected to the drainage culvert through drainage pipes. A grate is installed on the top of the sewer. Rainwater or domestic sewage flows into the sewer through the grate, and then flows from the sewer to the culvert for discharge.

[0003] In the related technology, a Chinese patent with publication number CN214461069U proposes a municipal engineering culvert anti-blocking structure, which further filters rainwater through a filter net to reduce the entry of debris into the drain pipe and culvert, thereby reducing the blockage of the drain pipe and culvert. When the first filter net is blocked, the water level of the sewer rises, and the rainwater can flow from the overflow pipe to the culvert, draining the rainwater in time, thereby reducing the accumulation of water on the road.

[0004] The above-mentioned related technologies have the following defects: during the use of this municipal engineering culvert anti-blocking structure for drainage and flood discharge, larger impurities flowing in with rainwater will be retained in the sewer by the filter net, which will affect the drainage effect of the sewer and drain pipe when more impurities accumulate.

DETAILED DESCRIPTION

[0022] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0023] The present application embodiment discloses a municipal engineering culvert blocking prevention structure. Figure 1 and Figure 2The anti-blocking structure of the municipal engineering culvert may include a drainage system 10, a drainage manhole cover 20, a drainage pipe 30, a filter assembly 40 and a cleaning manhole cover 50. An opening is formed at the top of the drainage system 10, and the inner cavity of the drainage system 10 is divided into two groups of chambers. The drainage manhole cover 20 and the cleaning manhole cover 50 are respectively covered on the two groups of chambers of the drainage system 10. Several groups of water leakage grooves are formed on the drainage manhole cover 20 along its length direction so that rainwater can flow into the drainage system 10. The drainage system 10 is used to guide rainwater on the road surface into the culvert for drainage and flood discharge. The top of the cleaning manhole cover 50 is set as a closed plane. After the cleaning manhole cover 50 is removed, the impurities in the drainage system 10 can be cleaned. The cleaning manhole cover 50 and the drainage manhole cover 20 are both flush with the top of the drainage system 10, so that the entire device can be flush with the road surface, thereby avoiding affecting the road traffic. The drainage pipe 30 is connected and arranged at the inner bottom of a group of chambers, and the filter assembly 40 is installed in the group of chambers, so that the filter assembly 40 filters the water flowing into the drainage pipe 30. In this embodiment, the drainage manhole cover 20 and the cleaning manhole cover 50 can be made of cast iron die-casting.

[0024] See also Figure 3 The drainage system 10 includes a sewer 11, a support frame 12 and a partition plate 13. An opening is formed at the top of the sewer 11, and the support frame 12 is fixedly connected to the inner top of the sewer 11, and the support frame 12 is used to support the drainage manhole cover 20 and the cleaning manhole cover 50. The partition plate 13 is fixed to the inner bottom of the sewer 11, and the top of the partition plate 13 is fixedly connected to the support frame 12, so that the partition plate 13 divides the inner cavity of the sewer 11 into two groups of independent chambers, and the two groups of chambers are used for diversion and temporary storage of impurities respectively. A connecting port 14 that connects the two groups of chambers is formed on the partition plate 13, and the connecting port 14 is used to cooperate with the filter assembly 40 to introduce the impurities trapped in the chamber used for diversion into the chamber used for temporary storage of impurities. A diversion slope 15 is arranged at the bottom of the chamber connected to the drain pipe 30 , i.e., the chamber for diversion. The diversion slope 15 is inclined toward the drain pipe 30 so that the filtered water flows toward the drain pipe 30 and is introduced into the underground channel.

[0025] See also Figure 4The filter assembly 40 includes a support structure 41, a filter plate 42, at least two groups of suspension ropes 43, winding disks 44 equal in number to the suspension ropes 43, two groups of rotating shafts 45, and at least two groups of torsion springs 46. The support structure 41 is detachably fixed to the bottom of the support bracket 12 in the drainage system 10 by bolts, and the support structure 41 is simultaneously located under the drainage manhole cover 20, and a notch is formed at the bottom of the support structure 41. The filter plate 42 is movably arranged on the inner side of the support structure 41, and the two opposite sides of the filter plate 42 are respectively fixedly connected to the ends of at least one group of suspension ropes 43, and the other end of each group of suspension ropes 43 is respectively fixedly connected to the outer wall of a group of winding disks 44, and each group of suspension ropes 43 is wound and rolled on the winding disk 44, and when the winding disk 44 rotates, the suspension ropes 43 on its outer wall can be rolled up or released, thereby driving the filter plate 42 to move inside the support structure 41. The groups of winding discs 44 on the same side are fixed on the outer wall of the rotating shaft 45, and the two groups of rotating shafts 45 are rotatably connected to the opposite sides of the support structure 41, so that the rotation of the rotating shaft 45 can drive the groups of winding discs 44 on the same side to deflect simultaneously. At least one group of torsion springs 46 is sleeved on each group of rotating shafts 45, and the two ends of the torsion springs 46 are respectively fixedly connected to the rotating shaft 45 and the support structure 41. After the filter plate 42 filters the water and traps impurities above it, the filter plate 42 can move downward under the action of gravity and pull the suspension rope 43, and the rotating shaft 45 deflects, at this time, the torsion spring 46 can be deformed by force; when the impurities on the filter plate 42 are reduced, the external force on the torsion spring 46 can be reduced, and it can reduce the torsional deformation, so that the rotating shaft 45 drives the winding disc 44 to deflect and reel the suspension rope 43 to a certain extent, and at this time, the filter plate 42 can be driven to move upward.

[0026] See also Figure 5The support structure 41 includes two groups of symmetrical hangers 411, low joists 412 and high joists 413. The tops of the two groups of hangers 411 are connected and fixed to the support bracket 12 in the drainage system 10 by bolts. The low joists 412 and the high joists 413 are welded and fixed at the bottom between the two groups of hangers 411. The height of the high joists 413 is greater than the height of the low joists 412, and the high joists 413 and the low joists 412 are located at both ends along the length direction of the hangers 411. The two groups of hangers 411, the low joists 412 and the high joists 413 form a gap at the bottom of the support structure 41. When the filter plate 42 is affected by the impurities accumulated above it and moves downward to contact the low joists 412 and the high joists 413 respectively, the filter plate 42 can be in an inclined state. The virtual plane formed by the connecting line of the connecting port 14 and the top of the low joist 412 and the top of the high joist 413 is parallel to each other, and the width of the connecting port 14 is adapted to the width of the filter plate 42, so that the impurities on the inclined filter plate 42 can slide through the connecting port 14 and fall into the chamber for temporarily storing impurities. After a period of time, the sanitation staff removes the cleaning manhole cover 50 to clean the chamber. After the impurities on the filter plate 42 are reduced, the force applied to the filter plate 42 is reduced, and the filter plate 42 is less inclined under the pull of the suspension rope 43.

[0027] In this embodiment, two groups of support platforms are fixedly connected to opposite sides of the two groups of hangers 411 , and the two groups of support platforms on the same side are rotatably connected to both ends of the rotating shaft 45 , so that the hangers 411 support the deflection of the rotating shaft 45 .

[0028] In this embodiment, the middle part of the two groups of hangers 411 is formed with an avoidance groove that runs through them, and several groups of ropes 43 located on the same side all pass through the avoidance groove, so that the winding or releasing activities of the ropes 43 are not affected by the interference of the hangers 411.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
