Description

Technical Field

[0001] The present invention relates to the technical field of underground drainage, and particularly relates to a drainage structure, a drainage system and a working method thereof for municipal underground pipelines. Background Art

[0002] With the acceleration of the urbanization process, the importance of the municipal road drainage system has become increasingly prominent. The drainage system is the main artery of the continuous development of urban construction, which is not only related to the daily life of urban residents, but also an important part of urban construction.

[0003] Currently, rainwater wells are often set up on the roadside of municipal roads, and a slightly inclined road surface is used to guide rainwater to flow into the rainwater wells. Under the scouring of rainwater flow, sundries on the road surface will also enter the drainage pipeline along with the rainwater. After a long time, there will be a situation where sundries accumulate in the drainage pipeline, affecting the flow of rainwater, resulting in the drainage volume being less than the inflow volume, causing a water accumulation zone to form at the rainwater inlet, which affects the safety of travel on rainy days, especially for pedestrians and cyclists on the non-motorized lane.

[0004] Although there are devices for filtering sundries at the rainwater inlets in the existing road drainage, relatively speaking, the capacity of the device to accommodate sundries is limited, and the filtered sundries are still on the flow path of the rainwater. The accumulation of sundries will affect the subsequent inflow of rainwater into the drainage pipeline, and it is necessary for sanitation workers to clean the device regularly. Since the number of devices corresponds to the number of rainwater inlets, the cleaning workload is heavy. Summary of the Invention

[0005] The purpose of the present invention is to provide a drainage structure, a drainage system and a working method thereof for municipal underground pipelines, which can reduce the influence of sundries on the drainage efficiency of the drainage pipeline and reduce the intensity of the cleaning work of sanitation workers.

[0006] The technical solution adopted by the present invention to solve the above problems is:

[0007] A drainage structure for municipal underground pipelines, comprising:

[0008] A plurality of drain pipes, which are connected to each other adjacent to each other;

[0009] A plurality of confluence pipes, which correspond to the rainwater inlets on the non-motorized lane one by one. The confluence pipes are located between two drain pipes and are connected to the adjacent confluence pipes and drain pipes. At least one water inlet is provided at the top of the confluence pipe;

[0010] Among them, a plurality of filter meshes for filtering sundries in rainwater are provided at the upper parts of the cavities of the drain pipe and the confluence pipe. At least one fan wheel is rotatably connected to the lower part of the cavity of the drain pipe. The plane where the rotation trajectory of the fan wheel is located is perpendicular to the plane where the drainage trajectory is located. A sundries box can be provided between adjacent confluence pipes and drain pipes. The sundries box is provided with a storage cavity for storing sundries and a drainage cavity for allowing rainwater to pass through. The storage cavity and the drainage cavity are arranged vertically. The two ends of the bottom end of the sundries box are respectively connected to the confluence pipe and the drain pipe, and the cavities of the confluence pipe and the drain pipe are communicated through the drainage cavity. The cavity of the drain pipe connected to the sundries box is communicated with the storage cavity. The top end of the sundries box is exposed on the green belt between the non-motor vehicle lane and the motor vehicle lane.

[0011] As a further improvement of the above technical solution, the confluence pipe and the drain pipe connected to the sundries box are respectively located at the front end and the rear end in the drainage direction.

[0012] As a further improvement of the above technical solution, the central axes of the connected confluence pipe and drain pipe are on the same straight line, and the bottom surface of the drainage cavity is lower than the bottom ends of the cavities of the drain pipe and the confluence pipe.

[0013] As a further improvement of the above technical solution, the filter meshes are inserted on the drain pipe and the confluence pipe. The aperture of the filter meshes decreases sequentially from top to bottom. A plurality of air guiding plates arranged at equal intervals are provided on the top surface of the filter meshes. The air guiding plates between adjacent filter meshes are arranged in a staggered manner. The air guiding plates are inclined relative to the filter meshes along the drainage direction.

[0014] As a further improvement of the above technical solution, the length of the sundries box is the same as the length of the drain pipe. An access opening is formed on the top surface of the sundries box. The access opening is communicated with the storage cavity, and a cover is provided on the access opening.

[0015] As a further improvement of the above technical solution, the two ends of the drain pipe and the confluence pipe and the two ends of the bottom end of the sundries box are respectively provided with a matching plugging structure and socket structure.

[0016] The present invention also provides a municipal underground pipeline drainage system, including:

[0017] A drainage pipeline, the structure of which is the same as that of the municipal underground pipeline drainage structure described in any one of the above technical solutions;

[0018] A plurality of water collecting tanks, which correspond to the confluence pipes one by one, and the water collecting tanks are installed on the rainwater inlets;

[0019] Among them, the water collecting tank is located obliquely above the confluence pipe, and the bottom end of the water collecting tank is connected to the water inlet on the corresponding confluence pipe through a connecting pipe.

[0020] As a further improvement of the above technical solution, there are two water inlets, which are respectively located on the side and top of the extension part at the top end of the confluence pipe. The connecting pipe is connected to the water inlet located on the side of the extension part. A number of drainage channels are provided on the green belt to guide the rainwater on the motor vehicle lane into the non-motor vehicle lane. The drainage channels are connected to the water inlet located on the top of the extension part through drainage pipes.

[0021] As a further improvement of the above technical solution, flip covers are provided on the openings at the bottom end of the connecting pipe and the top end of the drainage pipe, and torsion springs for applying a force to rotate the flip covers on them away from the extension part are provided on both the connecting pipe and the drainage pipe.

[0022] The present invention also provides a working method of the municipal underground pipeline drainage system according to any one of the above technical solutions, including the following steps:

[0023] Rainwater treatment: The rainwater on the non-motor vehicle lane and the motor vehicle lane is collected through the rainwater inlets and enters the water collection tank, and then flows downwards along the connecting pipe into the confluence pipe. During the process of rainwater flowing from the upper cavity of the confluence pipe to its lower cavity, the rainwater will flow through the filter screen, so that the filter screen filters out the sundries in the rainwater. Subsequently, the rainwater with sundries removed is discharged into the natural water body through the confluence pipe, the drainage pipe and the drainage cavity;

[0024] Sundries recycling: During the process of rainwater flowing and discharging, the rainwater can drive the fan wheel to rotate, thereby forming an air flow obliquely upward relative to the drainage direction. The air flow can dry the sundries on the filter screen and also blow the sundries off the filter screen, so that the sundries move along the drainage direction under the blowing of the air flow and enter the storage cavity for subsequent unified recycling and treatment.

[0025] Compared with the prior art, the present invention has the following advantages and effects:

[0026] (1) Through the structural settings of the confluence pipe and the drainage pipe, the present invention realizes the effects of filtering, discharging rainwater and recycling the sundries in the rainwater by the drainage pipeline, and can achieve the purpose of moving the sundries away from the rainwater flow track, thereby reducing the influence of sundries on the drainage efficiency of the drainage pipeline and reducing the risk of forming a water accumulation zone on the road surface.

[0027] (2) Through the structural settings of the sundries box and its installation position, while realizing the recycling of the sundries entering the drainage pipe, it also enables the sanitation workers to clean the sundries box together when staying to clean the rainwater inlets, reducing the work intensity.

Specific embodiments

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, and the present invention is not limited to the following embodiments.

[0040] See Figures 1 - 10, a municipal underground pipeline drainage system in this embodiment includes a drainage pipeline 1 and several water collection tanks 2. The drainage pipeline 1 includes several drain pipes 31 and several confluence pipes 32. Adjacent drain pipes 31 are connected to each other. The confluence pipes 32 correspond to the rainwater inlets on the non-motor vehicle lane one by one. The confluence pipes 32 are located between two drain pipes 31 and adjacent confluence pipes 32 and drain pipes 31 are connected. The top of the confluence pipe 32 is provided with a water inlet 33. Several filter meshes 41 for filtering sundries in rainwater are provided in the upper parts of the cavities of the drain pipes 31 and the confluence pipes 32. At least one fan wheel 42 is rotatably connected to the lower part of the cavity of the drain pipe 31. The plane where the rotation track of the fan wheel 42 is located is perpendicular to the plane where the drainage track is located. A sundries box 5 can be provided between adjacent confluence pipes 32 and drain pipes 31. The sundries box 5 is provided with a storage cavity 51 for storing sundries and a drainage cavity 52 for allowing rainwater to pass through. The storage cavity 51 and the drainage cavity 52 are arranged vertically. The two ends of the bottom end of the sundries box 5 are respectively connected to the confluence pipe 32 and the drain pipe 31, and the cavities of the confluence pipe 32 and the drain pipe 31 are communicated through the drainage cavity 52. The cavity of the drain pipe 31 connected to the sundries box 5 is communicated with the storage cavity 51. The top of the sundries box 5 is exposed on the green belt between the non-motor vehicle lane and the motor vehicle lane. The water collection tanks 2 correspond to the confluence pipes 32 one by one. The water collection tanks 2 are installed on the rainwater inlets. The water collection tanks 2 are located obliquely above the confluence pipes 32. The bottom end of the water collection tank 2 is connected to the water inlet 33 on the corresponding confluence pipe 32 through a connecting pipe 21.

[0041] In rainy weather, the rainwater on the non-motor vehicle lane and the motor vehicle lane can be collected through the rainwater inlets and enter the water collection tanks 2, and then flow into the confluence pipes 32 from top to bottom along the connecting pipes 21. And during the process of the rainwater flowing from the upper part of the cavity of the confluence pipe 32 to the lower part of its cavity, the rainwater will flow through the filter meshes 41, so that the filter meshes 41 filter out the sundries in the rainwater (such as leaves, waste paper, etc.). While reducing the risk of sundries accumulation in the drain pipes 31 affecting the rainwater flow rate, it also reduces the water quality pollution caused by the subsequent rainwater discharged into the natural water body. Subsequently, the rainwater with sundries removed is discharged into the natural water body through the confluence pipes 32, the drain pipes 31 and the drainage cavity 52.

[0042] During the process of the rainwater flowing and discharging, the rainwater can drive the fan wheel 42 to rotate, thereby forming an air flow obliquely upward relative to the drainage direction. The air flow can dry the sundries on the filter meshes 41 while also blowing the sundries up from the filter meshes 41, so that the sundries move along the drainage direction under the blowing of the air flow and enter the storage cavity 51 for subsequent unified recycling and treatment. And because the air flow velocity in the drainage pipeline 1 is increased, a pressure difference is generated between the confluence pipe 32 and the connecting pipe 21, thereby accelerating the flow rate of the rainwater in the connecting pipe 21 and achieving the effect of quickly collecting rainwater at the rainwater inlets.

[0043] To reduce the workload of sundry recycling, the number of the sundry boxes 5 is less than that of the water collecting tanks 2, and the sundry boxes 5 are arranged at equal intervals, so that one sundry box 5 is used for the recycling and storage of sundries falling into multiple water collecting tanks 2.

[0044] See Figures 2 - 4 , there are two water inlets 33, and the two water inlets 33 are respectively located on the side surface and the top surface of the extension part 34 at the top end of the confluence pipe 32. The connecting pipe 21 is connected to the water inlet 33 located on the side surface of the extension part 34. A number of drainage channels 6 are provided on the green belt to guide the rainwater on the motor vehicle lane into the non-motor vehicle lane, reducing the risk that the rainwater splashes into the non-motor vehicle lane when the vehicle passes through the water accumulation zone formed by the rainwater on the motor vehicle lane, affecting pedestrians and cyclists, improving the safety of traveling on rainy days, and at the same time reducing the amount of rainwater on the motor vehicle lane flowing into the non-motor vehicle lane through the intersection connecting the motor vehicle lane and the non-motor vehicle lane, thereby improving the safety of pedestrians and cyclists passing through the intersection. The drainage channel 6 is connected to the water inlet 33 located on the top surface of the extension part 34 through a drainage pipe 61, so that a part of the rainwater flowing through the drainage channel 6 can directly enter the confluence pipe 32 through the drainage pipe 61, accelerating the collection of rainwater into the drainage pipeline 1 and reducing the risk of forming a water accumulation zone due to the sudden increase in the amount of rainwater in the non-motor vehicle lane.

[0045] See Figure 3 , flip covers 7 are provided at the openings at the bottom end of the connecting pipe 21 and the top end of the drainage pipe 61. Torsion springs for applying a force to rotate the flip covers 7 on them away from the extension part 34 are provided on the connecting pipe 21 and the drainage pipe 61, so that when there is no rainwater entering the connecting pipe 21 and the drainage pipe 61, the flip covers 7 can disconnect the connection between the confluence pipe 32 and the connecting pipe 21 and the drainage channel 6, reducing the risk that the sundries in the drainage pipeline 1 are discharged through the connecting pipe 21 and the drainage pipe 61 driven by the air flow, thereby ensuring the effect of the air flow formed by the rotation of the fan wheel 42 on the sundries on the filter screen 41 in the drainage pipeline 1.

[0046] See Figure 4 , the confluence pipe 32 and the drain pipe 31 connected to the sundry box 5 are respectively located at the front end and the rear end in the drainage direction, reducing the risk that the sundries in the storage cavity 51 are splashed and wetted when the rainwater enters the confluence pipe 32, and ensuring the dryness of the sundries in the storage cavity 51 and the sundries entering the storage cavity 51.

[0047] See Figures 5 - 7, the filter screen 41 is inserted on the drain pipe 31 and the confluence pipe 32. The aperture of the filter screen 41 decreases successively from top to bottom, ensuring the filtering effect of the filter screen 41 on the sundries in the rainwater. A number of air guide plates 43 arranged at equal intervals are provided on the top surface of the filter screen 41. The air guide plates 43 on adjacent filter screens 41 are arranged in a staggered manner, so that the sundries can be placed on the adjacent air guide plates 43, thereby improving the drying effect of the air flow on the sundries while reducing the difficulty of the air flow blowing up the sundries. The air guide plates 43 are inclined relative to the filter screen 41 along the drainage direction, playing a role in guiding the air flow and ensuring the accuracy of the moving direction of the sundries under the action of the air flow.

[0048] See Figure 5 , Figure 8 and Figure 9 , the two ends of the drain pipe 31 and the confluence pipe 32 and the two ends of the bottom of the sundry box 5 are respectively provided with a matching plug-in structure 81 and a socket structure 82, which can play a positioning role during connection and improve the convenience of assembling the drainage pipeline 1.

[0049] See Figure 9 , Figure 10 , the length of the sundry box 5 is the same as that of the drain pipe 31. Under the condition of ensuring the equal-spacing setting of the rainwater inlets, the requirement of the sundry box 5 for different length specifications of the drain pipe 31 is reduced, and the unity and standardization of the specifications of the drain pipe 31 and the confluence pipe 32 are improved. An access opening 53 is opened on the top surface of the sundry box 5, and the access opening 53 is communicated with the storage cavity 51, which facilitates the recycling of the sundries accumulated in the storage cavity 51. A cover 54 is provided on the access opening 53.

[0050] In this embodiment, the sundry box 5 includes a main body 55 and an extension pipe 56. The storage cavity 51 and the drainage cavity 52 are both located on the main body 55. The cross-section of the main body 55 is square. The socket structure 82 is located on the side surface of one end of the main body 55. The confluence pipe 32 is connected to one end of the main body 55. The structure of the extension pipe 56 is the same as that of the drain pipe 31. One end of the extension pipe 56 is connected to the side surface of the other end of the main body 55. The plug-in structure 81 is located on the other end of the extension pipe 56. The drain pipe 31 is connected to the other end of the extension pipe 56, improving the utilization of the length space inside the sundry box 5.

[0051] See Figure 9 , the central axes of the connected confluence pipe 32 and drain pipe 31 are on the same straight line. The bottom surface of the drainage cavity 52 is lower than the bottom ends of the cavities of the drain pipe 31 and the confluence pipe 32, ensuring the flow of rainwater in the drainage pipeline 1.

[0052] The above content described in this specification is only an example of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the specific embodiments described or use similar methods for substitution, as long as they do not deviate from the content of this specification of the present invention or exceed the scope defined by this claims, and shall fall within the protection scope of the present invention.
