Description

Technical Field

[0001] This application relates to the technical field of municipal drainage construction, and in particular to a municipal rain and sewage diversion system. Background Art

[0002] In municipal construction, the drainage system is an engineering facility system for treating wastewater in the city, providing a basic guarantee for the normal operation of the city. The wastewater in the city usually includes domestic sewage and rainwater. Therefore, the drainage system mainly collects, treats, and discharges domestic sewage and rainwater.

[0003] In the related art, the drainage system in the city often adopts a rain and sewage diversion system, with a rainwater pipe and a sewage pipe independently set. The rainwater pipe collects rainwater and directly discharges it into the river, and the sewage pipe collects domestic sewage and enters the sewage treatment plant. After treatment, it is centrally discharged. On the one hand, it can avoid direct pollution of the river by sewage, and on the other hand, it can reduce the impact of the water volume on the sewage treatment plant and improve the treatment efficiency of the sewage treatment plant.

[0004] Regarding the above related art, the inventor believes that there are the following defects: In the normal operation of the city, rainwater will inevitably carry some sundries such as domestic garbage, leaves, and soil into the rainwater pipe, which may cause pollution to the river. Summary of the Invention

[0005] In order to reduce the possibility of pollution to the river, this application provides a municipal rain and sewage diversion system.

[0006] The municipal rain and sewage diversion system provided by this application adopts the following technical solutions:

[0009] By adopting the above technical solutions, in order to reduce the possibility of pollution to the river, when rainwater carries sundries such as domestic garbage, leaves, and soil and flows through the rainwater pipe, under the filtering action of the filter screen, the water flow passes through the filter screen and continues to move in the rainwater pipe, and the sundries are filtered on the filter screen. Due to the inclined setting of the filter screen, the sundries can enter the sewage pipe through the connecting pipe under the action of gravity, so that the sundries carried in the rainwater can be diverted into the sewage pipe and enter the sewage treatment plant for treatment, reducing the possibility of sundries directly entering the river, and thus achieving the purpose of reducing the possibility of pollution to the river.

The reciprocating movement of the sliding frame drives the pushing bar to reciprocate. Under the action of the inclined surfaces of the pushing bar and the second rack, when the pushing bar moves towards the second rack, the pushing bar can push the second rack to move; when the pushing bar moves away from the second rack, the pushing bar gradually stops contacting the second rack, and at the same time, under the elastic force of the second spring, the second rack moves in the reverse direction, so as to achieve the purpose of driving the second rack to reciprocate.

[0031] A driven bevel gear is fixedly connected to the screw, a driving bevel gear is fixedly connected to the rotating shaft, and the driving bevel gear meshes with the driven bevel gear.

[0049] The following is combined with the attached Figures 1-7Further details of this application will be described below.

[0050] An embodiment of this application discloses a municipal rainwater and sewage diversion system. Referring to Figure 1 and Figure 2 , the municipal rainwater and sewage diversion system includes a rainwater pipe 1, a sewage pipe 2, and a filter screen 3. A connecting pipe 4 is provided between the rainwater pipe 1 and the sewage pipe 2. The rainwater pipe 1 and the sewage pipe 2 are both fixedly connected to the connecting pipe 4, and the rainwater pipe 1 and the sewage pipe 2 are both in communication with the connecting pipe 4; the filter screen 3 is arranged in the rainwater pipe 1. Four connecting columns 31 are fixedly connected to the filter screen 3, and a first spring 32 is fixedly connected to each connecting column 31. The four first springs 32 are all fixedly connected to the inner wall of the rainwater pipe 1; a vibrating bar 33 is fixedly connected to the bottom of the filter screen 3, and the filter screen 3 is arranged obliquely downward from the end far away from the connecting pipe 4 to the end close to the connecting pipe 4.

[0051] When rainwater carrying sundries such as domestic garbage, leaves, and soil flows through the rainwater pipe 1, under the filtering action of the filter screen 3, the water flow passes through the filter screen 3 and continues to move in the rainwater pipe 1, and the sundries are filtered on the filter screen 3. Since the filter screen 3 is obliquely arranged, the sundries can enter the sewage pipe 2 through the connecting pipe 4 under the action of gravity, so that the sundries carried in the rainwater can be diverted into the sewage pipe 2 and enter the sewage treatment plant for treatment, reducing the possibility of the sundries directly entering the river, and thus achieving the purpose of reducing the possibility of polluting the river; at this time, the vibrating bar 33 is driven to reciprocate, and the reciprocating movement of the vibrating bar 33 drives the filter screen 3 to reciprocate, thereby reducing the possibility of sundries adhering to the filter screen 3 and facilitating the sundries to enter the sewage pipe 2 through the connecting pipe 4; under the elastic force of the four first springs 32, the filter screen 3 can be buffered, reducing the possibility of the filter screen 3 being damaged.

[0052] As Figure 2 and Figure 3 shown, a vibration mechanism 5 is arranged in the rainwater pipe 1. The vibration mechanism 5 includes a first rack 51, a second rack 52, and a first gear 53. The first rack 51 is fixedly connected to the vibrating bar 33, and the second rack 52 penetrates through the side wall of the rainwater pipe 1 and is slidably connected to the rainwater pipe 1; a support rod 11 is rotatably connected to the inner wall of the rainwater pipe 1, and the first gear 53 is fixedly connected to the support rod 11. The first rack 51 and the second rack 52 are both meshed with the first gear 53; a fixing plate 54 is fixedly connected to the second rack 52, and a second spring 55 is fixedly connected to the fixing plate 54. The second spring 55 is fixedly connected to the inner wall of the rainwater pipe 1.

[0053] When rainwater carrying domestic waste, leaves, soil and other debris flows through the rainwater pipe 1, it first drives the second rack 52 to move. Utilizing the elastic force of the second spring 55, it is convenient for the second rack 52 to reset, so that the second rack 52 can reciprocate. The reciprocating movement of the second rack 52 drives the first gear 53 to rotate periodically forward and backward. The periodic forward and backward rotation of the first gear 53 drives the first rack 51 to reciprocate. The reciprocating movement of the first rack 51 drives the vibrating bar 33 to reciprocate, so as to achieve the purpose of driving the vibrating bar 33 to reciprocate.

[0054] As Figure 2 and Figure 4 shown, a driving component 6 is arranged on the rainwater pipe 1. The driving component 6 includes a sliding frame 61 and a pushing bar 62. The sliding frame 61 is slidably connected to the outer wall of the rainwater pipe 1, and the pushing bar 62 is fixedly connected to the sliding frame 61; an inclined surface is arranged on the pushing bar 62, and the inclined surface of the pushing bar 62 is inclined downward from the end close to the sliding frame 61 to the end far from the sliding frame 61; an inclined surface is arranged on the second rack 52, and the inclined surface of the second rack 52 can be fitted with the inclined surface of the pushing bar 62.

[0055] When rainwater carrying domestic waste, leaves, soil and other debris flows through the rainwater pipe 1, it first drives the sliding frame 61 to reciprocate. The reciprocating movement of the sliding frame 61 drives the pushing bar 62 to reciprocate. Under the action of the inclined surfaces of the pushing bar 62 and the second rack 52, when the pushing bar 62 moves toward the second rack 52, the pushing bar 62 can push the second rack 52 to move; when the pushing bar 62 moves away from the second rack 52, the pushing bar 62 gradually stops contacting the second rack 52, and at the same time, under the elastic force of the second spring 55, the second rack 52 moves in the reverse direction, so as to achieve the purpose of driving the second rack 52 to reciprocate.

[0056] As Figure 4 shown, a moving component 7 is arranged on the rainwater pipe 1. The moving component 7 includes a third rack 71, a fourth rack 72 and a first half gear 73. The third rack 71 is fixedly connected to the left inner side wall opposite to the sliding frame 61, and the fourth rack 72 is fixedly connected to the right inner side wall opposite to the sliding frame 61; a rotating shaft 12 is rotatably connected to the rainwater pipe 1, and the first half gear 73 is fixedly connected to the rotating shaft 12. Both the third rack 71 and the fourth rack 72 can be engaged with the first half gear 73.

[0057] When rainwater carrying domestic waste, leaves, soil and other debris flows through the rainwater pipe 1, it first drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives the first half gear 73 to rotate. The rotation of the first half gear 73 alternately drives the third rack 71 and the fourth rack 72 to move. The movement of the third rack 71 drives the sliding frame 61 to move downward, and the movement of the fourth rack 72 drives the sliding frame 61 to move upward, so as to achieve the purpose of driving the sliding frame 61 to reciprocate.

[0058] As Figure 2 shown, a rotating assembly 8 is provided on the rainwater pipe 1. The rotating assembly 8 includes a rotating ring 81 and six flap plates 82. The rotating ring 81 is fixedly connected to the rotating shaft 12, and the six flap plates 82 are all fixedly connected to the rotating ring 81. The six flap plates 82 are equidistantly arranged along the circumference of the rotating ring 81. A through hole 13 is formed in the rainwater pipe 1, so that the six flap plates 82 can all rotate inside the rainwater pipe 1. A water isolation cover 14 is fixedly connected to the outer wall of the rainwater pipe 1. By means of the water isolation cover 14, the possibility of water flowing through the through hole 13 into the soil layer can be reduced.

[0059] When rainwater carrying domestic garbage, leaves, soil and other sundries flows through the rainwater pipe 1, the water flow can push the flap plate 82 located in the rainwater pipe 1 to rotate. The rotation of the six flap plates 82 drives the rotation of the rotating ring 81, and the rotation of the rotating ring 81 drives the rotation of the rotating shaft 12, so as to achieve the purpose of driving the rotation of the rotating shaft 12.

[0060] As Figure 5 shown, a cleaning brush 9 is provided in the rainwater pipe 1. The brush head part of the cleaning brush 9 is slidably connected to the filter screen 3. A screw rod 91 is rotatably connected in the rainwater pipe 1. A spiral ring 92 is fixedly connected to the cleaning brush 9, and the spiral ring 92 is threadedly connected to the screw rod 91. A guide rod 93 is fixedly connected to the side wall of the rainwater pipe 1. The guide rod 93 penetrates through the spiral ring 92, and the guide rod 93 is slidably connected to the spiral ring 92. The screw rod 91 penetrates through the side wall of the rainwater pipe 1, and a driven bevel gear 94 is fixedly connected to the screw rod 91. A driving bevel gear 95 is fixedly connected to the rotating shaft 12, and the driving bevel gear 95 meshes with the driven bevel gear 94.

[0061] When rainwater carrying domestic garbage, leaves, soil and other sundries flows through the rainwater pipe 1, the rotation of the rotating shaft 12 drives the rotation of the driving bevel gear 95. The rotation of the driving bevel gear 95 drives the rotation of the driven bevel gear 94. The rotation of the driven bevel gear 94 drives the rotation of the screw rod 91. The rotation of the screw rod 91 drives the movement of the spiral ring 92. By means of the guide rod 93, the movement of the spiral ring 92 can be guided. The movement of the spiral ring 92 drives the movement of the cleaning brush 9. The movement of the cleaning brush 9 drives the movement of the sundries on the filter screen 3, so as to further reduce the possibility of sundries adhering to the filter screen 3 and achieve the purpose of facilitating the sundries to enter the sewage pipe 2 through the connecting pipe 4.

[0062] As Figure 6 and Figure 7 shown, a check plate 21 is hinged on the sewage pipe 2. The check plate 21 can block the pipe orifice of the connecting pipe 4. A first torsion spring 22 is fixedly connected to the check plate 21, and the first torsion spring 22 is fixedly connected to the inner wall of the sewage pipe 2. A limiting plate 23 is fixedly connected to the inner wall of the sewage pipe 2, and the check plate 21 can be attached to the limiting plate 23.

[0063] Under normal conditions, due to the elastic force of the first torsion spring 22, the check valve plate 21 can be in contact with the limit plate 23 to block the nozzle of the communication pipe 4. With the function of the limit plate 23, the possibility of excessive rotation of the check valve plate 21 can be reduced, thereby reducing the possibility of sewage in the sewage pipe 2 entering the rainwater pipe 1. When the debris in the rainwater pipe 1 moves through the communication pipe 4, the debris can push the check valve plate 21 to rotate, allowing the debris to enter the sewage pipe 2.

[0064] The implementation principle of a municipal rain and sewage diversion system according to an embodiment of the present application is as follows: In order to reduce the possibility of polluting the river, when rainwater carrying domestic waste, leaves, soil and other debris flows through the rainwater pipe 1, under the filtering action of the filter screen 3, the water flow passes through the filter screen 3 and continues to move in the rainwater pipe 1, and the debris is filtered on the filter screen 3. Since the filter screen 3 is inclined, the debris can enter the sewage pipe 2 through the communication pipe 4 under the action of gravity, thereby diverting the debris carried in the rainwater to the sewage pipe 2 and entering the sewage treatment plant for treatment, reducing the possibility of debris directly entering the river, and thus achieving the purpose of reducing the possibility of polluting the river.

[0065] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
