DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, an embodiment of the present invention provides a rainwater and sewage diversion device for a pipe network, comprising a box body 1, the bottom of the box body 1 is connected with a mixed water drain pipe 4 and a sewage drain pipe 5, the top of the mixed water drain pipe 4 is provided with a protective cover 12, two support plates 6 are fixed inside the box body 1, filter plates 7 are provided on the top of the two support plates 6, a connecting rod 8 is fixed to the top outer wall of the filter plate 7, a pull ring 9 is fixed to the top of the connecting rod 8, one side outer wall of the box body 1 is connected to a water inlet pipe 11 located on the top of the filter plate 7, an inner box 2 is fixed inside the box body 1, an overflow port 21 is opened on the outer wall of one side of the inner box 2, a protective cover 2 13 is provided on the top of the sewage drain pipe 5, and a driving mechanism is provided on the top of the protective cover 2 13 and the protective cover 1 12.

[0022] Specifically, in this embodiment, it includes a box body 1, and the bottom of the box body 1 is connected with a mixed water drain pipe 4 and a sewage drain pipe 5. The mixed water drain pipe 4 is used to discharge mixed water composed of rainwater and sewage, and the sewage drain pipe 5 is used to discharge sewage. A protective cover 12 is provided on the top of the mixed water drain pipe 4. When simply discharging sewage, the protective cover 12 keeps the mixed water drain pipe 4 covered to prevent sewage from flowing into the mixed water drain pipe 4. Two support plates 6 are fixed inside the box body 1, and filter plates 7 are provided on the top of the two support plates 6. The filter plates 7 are directly placed on the support plates 6. The filter plates 7 filter impurities in the sewage, especially fixed impurities that are easy to form deposits, for example: stones that enter the drainage pipe after being washed by rainwater, and then the stones are carried into the interior of the box body 1 for a long time after being carried by sewage. A connecting rod 8 is fixed to the top outer wall of the filter plate 7, and a pull ring 9 is fixed to the top of the connecting rod 8. The rod 8 can lift the filter plate 7. The outer wall of one side of the box body 1 is connected to the water inlet pipe 11 located on the top of the filter plate 7. The water inlet pipe 11 is connected to the drainage pipe through which sewage and rainwater flow uniformly. An inner box 2 is fixed inside the box body 1. The side wall of the inner box 2 and the inner wall of the box body 2 form a cavity, so that the filter plate 7 filters the water entering the cavity. An overflow port 21 is provided on the outer wall of one side of the inner box 2; when the water flow rate entering the cavity from the water inlet pipe 11 is large, the water flow rate at this time is greater than the peak value of sewage entering from the water inlet pipe 11, that is, there is a large amount of mixed water formed by rainwater and sewage. The mixed water will not be able to pass through the filter plate 7 in time, and will enter the interior of the inner box 2 from the overflow port 21. A protective cover 2 13 is provided on the top of the sewage drain pipe 5, and a driving mechanism is provided on the top of the protective cover 2 13 and the protective cover 1 12. The driving mechanism is used to drive the protective cover 2 13 and the protective cover 1 12 to move up and down.

[0023] The utility model provides a rainwater and sewage diversion device for a pipe network, which filters the sewage flowing in from the water inlet pipe 11 through the provided filter plate 7 to prevent the sedimentation of debris in the sewage at the bottom of the box body 1, so that when the rainwater and sewage are diverted, the protective cover 13 can be ensured to be normally closed to the sewage discharge pipe 5, making the rainwater and sewage diversion more reliable, and the filter plate 7 can be conveniently lifted by the pull ring 9 and the connecting rod 8, thereby facilitating the cleaning of debris on the filter plate 7.

[0024] In another embodiment provided by the present invention, the driving mechanism includes a lever 23, a rotating shaft 22 is fixed in the middle of the lever 23, and both ends of the rotating shaft 22 are rotatably connected to the inner box 2. A guide column 16 and a guide column 2 17 are hinged on the outer wall of one side of the lever 23. The guide column 16 and the guide column 2 17 are respectively on both sides of the rotating shaft 22, and the tops of the guide column 16 and the guide column 2 17 can slide with a small distance between them and the lever 23. The bottom end of the guide column 16 is fixed to the protective cover 12, and the bottom end of the guide column 2 17 is fixed to the protective cover 2 13. A float 18 is provided at one end of the lever 23; when there is no water inside the inner box 2, the float 18 will pull one end of the lever 23 by gravity. The vent pipe 10 is connected to the top of the box body 1, and the vent pipe 10 is a curved pipe. When the water in the box body 1 gradually increases, the air in the box body 1 can flow out in time. The bottom of the inner box 2 is provided with a small drainage pipe, so that the water in the inner box 2 can flow out quickly. The water can flow out slowly, and then when there is no rain, the float 18 will drop and reset due to the reduction of water volume; the bottom inner wall of the inner box 2 is fixed with a guide cylinder 15 and a guide cylinder 2 14, the guide column 16 is inserted into the inside of the guide cylinder 15, and the guide column 2 17 is inserted into the inside of the guide cylinder 2 14. The guide cylinder 15 and the guide cylinder 2 14 make the guide columns 16 and the guide columns 17 more stable when they move up and down; the bottom outer wall of the float 18 is fixed with a vertical rod 19, one end of the vertical rod 19 is hinged to the lever 23, and the vertical rod 19 is hinged to the lever 23, so that when the water inside the inner box 2 increases, the float 18 can be kept horizontal and lifted. The interior of the inner box 2 is fixed with a float located at the bottom. There are two support rods 20 at the bottom of 18, and the float 18 is located inside the inner box 2. The support rods 20 are used to support the float 18 so that the float 18 can remain horizontal even when it is in a low position; at the same time, when a small flow of mixed water formed by a small flow of rainwater and a small flow of sewage enters the box body 1 from the water inlet pipe 11, since the proportion of rainwater is small at this time, the float 18 will not rise, and the water will be directly discharged from the sewage pipe 5. The top outer wall of the box body 1 is hinged with an inspection cover 3, which is adapted to the filter plate 7. After the inspection cover 3 is opened, the filter plate 7 can be taken out from the inspection port at the inspection cover 3, so that the filter plate 7 is easy to clean or replace.

[0025] Working principle: When in use, when only sewage enters the box body 1 from the water inlet pipe 11, the sewage flowing in from the water inlet pipe 11 is slow and cannot reach the overflow port 21. The sewage is filtered by the filter plate 7 so that the solid particles in the sewage are intercepted by the filter plate 7, and then the filtered sewage is discharged from the sewage drain pipe 5; when the mixed water composed of sewage and rainwater enters from the water inlet pipe 11 together, the mixed water flowing in from the water inlet pipe 11 is large in volume and rapid, and the mixed water can reach the overflow port 21. Part of the mixed water will enter the interior of the inner box 2 from the overflow port 21, causing the float 18 inside the inner box 2 to rise by buoyancy. The rise of the float 18 drives the lever 23 to rotate with the rotating shaft 22 as the axis, so that the protective cover 12 is separated from the mixed water drain pipe 4, and the protective cover 2 13 closes the sewage drain pipe 5, so that the mixed water is discharged from the opened mixed water drain pipe 4.

[0026] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
