Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, and specifically relates to a municipal engineering drainage structure. Background Technology

[0002] Municipal engineering refers to various infrastructure projects in urban construction, including urban roads and bridges, water supply and drainage systems, power supply systems, and communication systems; among them, drainage systems are a very important part of municipal engineering, used to collect, transport, and treat sewage and rainwater in cities;

[0003] The drainage structure of municipal engineering mainly consists of structures such as rainwater inlets, drainage pipes, drainage ditches, and infiltration wells. Simply put, sewage first flows into the sewage inlet, and then is transported to downstream drainage facilities or sewage treatment plants through underground drainage pipes. Finally, the treated sewage is discharged into rivers and lakes, or used for reuse such as agricultural irrigation and industrial water.

[0004] During heavy rain, urban roads often become flooded. If the floodwater becomes too deep, it can cause traffic paralysis and affect driving safety. One of the reasons for road flooding is that sewage contains large debris, which can block the sewage outlets, making it difficult for water on the road surface to pass through, thus affecting the drainage effect. Therefore, a municipal engineering drainage structure is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage structure for municipal engineering to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a municipal engineering drainage structure, comprising:

[0007] A drainage well, the bottom of which has a debris trough, and the drainage well has multiple spaced water inlets on opposite side walls of the debris trough. A drainage pipe is also installed on the outside of the drainage well, and the water inlets are connected to the drainage pipe.

[0008] A manhole cover, which is installed on the upper end of the drainage well;

[0009] A filter assembly, comprising a filter plate, wherein a pair of filter plates are provided, one end of the pair of filter plates is rotatably mounted on the inner wall of the drainage well, the pair of filter plates are inclined and symmetrically distributed with the debris trough as the center.

[0010] As a preferred embodiment, the filter assembly further includes connecting rods and rotating rods. The connecting rods are provided in two sets, with two connecting rods in each set. One end of each connecting rod is rotatably mounted to the lower end of the filter plate, and the other end of the connecting rod is rotatably mounted to the rotating rod.

[0011] As a preferred embodiment, the filter assembly further includes a lifting rod and a limiting block. The rotating rod has a mounting hole at its middle position, the lifting rod is inserted into the mounting hole, and the limiting block is fixedly installed at the lower end of the lifting rod. The limiting block has a circular cross-section, and the diameter of the limiting block's cross-section is larger than the diameter of the mounting hole.

[0012] As a preferred embodiment, the upper end of the lifting rod has a limiting plate, the upper surface of the manhole cover has an insertion hole and a limiting groove, the upper end of the lifting rod is inserted into the insertion hole, and the limiting plate is placed in the limiting groove.

[0013] As a preferred embodiment, the drainage well also includes a mounting plate, which is provided in two sets, with two mounting plates in each set. The two mounting plates are installed vertically, and the lower end of the filter plate is attached to the upper surface of one of the horizontally installed mounting plates. The debris trough is provided between the two horizontally installed mounting plates in the two sets, and the upper end of the filter plate is attached to the side wall of the other vertically installed mounting plate.

[0014] As a preferred embodiment, two of the horizontally mounted mounting plates in the two groups have multiple spaced-apart drain tanks, and the filter plate has multiple spaced-apart filter holes, with the drain tanks and filter holes connected in communication.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a filter assembly comprising a pair of filter plates arranged at an angle, symmetrically distributed around a debris trough. Under gravity, debris in rainwater cannot pass through the filter holes and remains on the upper surface of the filter plates. The filtered rainwater flows through the filter holes and the drainage trough, eventually entering downstream drainage facilities or sewage treatment plants via drainage pipes. When the debris remaining on the upper surface of the filter plates is heavy or accumulates excessively, it slides down the inclined surface of the filter plates into the debris trough, and some rainwater flows into the drainage pipes through the inlets on both sides of the debris trough, preventing the debris from clogging the filter plates and causing road flooding.

[0017] This invention features a connecting rod and a rotating rod. One end of the connecting rod is rotatably mounted to the lower end of the filter plate, and the other end is rotatably mounted to the rotating rod. The rotating rod has a mounting hole in its middle, into which a lifting rod is inserted. A limiting block is fixedly mounted to the lower end of the lifting rod. The limiting block has a circular cross-section, with a diameter larger than the mounting hole diameter. Workers move the lifting rod up and down, causing the filter plate to rotate continuously. The lower end of the filter plate continuously strikes the horizontally mounted mounting plate, causing debris blocking the filter holes to be ejected and slide down the inclined surface of the filter plate into a debris trough. This prevents rainwater from accumulating in the drainage well due to blockage of the filter holes, thus reducing road flooding. Attached Figure Description

[0026] Please see Figure 1-5 This utility model provides a municipal engineering drainage structure, comprising:

[0027] The drainage well 1 has a debris trough 11 at its bottom. The drainage well 1 has multiple spaced water inlets 12 on the opposite side walls of the debris trough 11. A drainage pipe 13 is also installed on the outside of the drainage well 1, and the water inlets 12 are connected to the drainage pipe 13.

[0028] Manhole cover 2 is installed at the upper end of drainage well 1;

[0029] The filter assembly 3 includes a filter plate 31, and a pair of filter plates 31 are provided. One end of the pair of filter plates 31 is rotatably installed on the inner wall of the drainage well 1. The pair of filter plates 31 are inclined and symmetrically distributed with the debris trough 11 as the center.

[0030] The filter assembly 3 also includes a connecting rod 32 and a rotating rod 33. There are two sets of connecting rods 32, with two connecting rods in each set. One end of each set of connecting rods 32 is rotatably mounted on the lower end of the filter plate 31, and the other end of the connecting rod 32 is rotatably mounted on the rotating rod 33.

[0031] The filter assembly 3 also includes a lifting rod 34 and a limiting block 35. The middle position of the rotating rod 33 has a mounting hole 331. The lifting rod 34 is inserted into the mounting hole 331. The limiting block 35 is fixedly installed at the lower end of the lifting rod 34. The cross-section of the limiting block 35 is set to be circular, and the diameter of the cross-section of the limiting block 35 is larger than the diameter of the mounting hole 331.

[0032] The upper end of the lifting rod 34 has a limiting plate 341, and the upper end face of the well cover 2 has an insertion hole 21 and a limiting groove 22. The upper end of the lifting rod 34 is inserted into the insertion hole 21, and the limiting plate 341 is placed in the limiting groove 22.

[0033] The drainage well 1 also includes a mounting plate 14. There are two sets of mounting plates 14, and each set has two mounting plates 14. The two mounting plates 14 are installed vertically. The lower end of the filter plate 31 is attached to the upper surface of one of the horizontally installed mounting plates 14. The debris trough 11 is located between the two horizontally installed mounting plates 14 in the two sets. The upper end of the filter plate 31 is attached to the side wall of the other vertically installed mounting plate 14.

[0034] Two horizontally mounted mounting plates 14 in the two sets have multiple spaced-apart drain troughs 141, and filter plates 31 have multiple spaced-apart filter holes 311. The drain troughs 141 and filter holes 311 are connected.

[0035] Working principle and usage process of this utility model:

[0036] In the initial state, the limiting plate 341 is placed in the limiting groove 22 and the limiting plate 341 is placed on the bottom wall of the debris groove 11; rainwater mixed with debris enters the interior of the drainage well 1 through the manhole cover 2, some of the debris is placed on the upper surface of the manhole cover 2, and the rest of the debris enters the interior of the drainage well 1 with the rainwater.

[0037] Under the influence of gravity, debris in the rainwater cannot pass through the filter holes 311 and remains on the upper surface of the filter plate 31. The filtered rainwater passes through the filter holes 311 and the drain trough 141, and finally flows into the downstream drainage facilities or sewage treatment plant through the drainage pipe 13. When the debris remaining on the upper surface of the filter plate 31 is heavy or accumulates too much, the debris slides along the inclined surface of the filter plate 31 into the debris trough 11, and some rainwater flows into the drainage pipe 13 through the inlets 12 on both sides of the debris trough 11. After a period of time, workers can open the manhole cover 2 to clean the debris accumulated in the debris trough 11. The operation is simple and convenient for workers to maintain regularly.

[0038] After the debris clogs the filter hole 311, the worker first removes the limiting plate 341 from the limiting groove 22, and then pulls the lifting rod 34 upward through the limiting plate 341, so that the limiting plate 341 at the lower end of the lifting rod 34 drives the rotating rod 33 to move upward as well; in this way, the included angle between the connecting rod 32 and the rotating rod 33 decreases, thereby driving one end of the filter plate 31, which is rotatably connected to the other end of the connecting rod 32, to move upward.

[0039] The worker moves the lifting rod 34 up and down, causing the filter plate 31 to rotate continuously, and the lower end of the filter plate 31 to continuously strike the horizontally installed mounting plate 14. Under the vibration, the debris blocking the filter holes 311 is ejected from the filter holes 311 and slides down the inclined surface of the filter plate 31 into the debris trough 11, so as to prevent rainwater from accumulating in the drainage well 1 after the filter holes 311 on the filter plate 31 are blocked by debris, thus reducing the occurrence of road water accumulation.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
