Description

Technical Field

[0001] This utility model relates to the field of municipal road drainage technology, and in particular to a prefabricated rainwater inlet. Background Technology

[0002] A storm drain is a structure used to collect rainwater in storm drains or combined sewer systems. Rainwater from the street surface first flows through the storm drain into the connecting pipe, and then through the connecting pipe into the drainage system. The form, number, and arrangement of storm drains should be determined based on the catchment area, the drainage capacity of the storm drains, and the road type. The installation of storm drains enables the rapid and effective collection of rainwater from the ground.

[0003] Generally, the initial rainfall is relatively small. After various pollutants on the street surface are washed away by the rainwater, they easily form initial rainwater carrying pollutants. The initial rainwater carries a high content of pollutants, and the existing rainwater inlets do not have the ability to intercept pollutants in the initial rainwater. The initial rainwater carrying pollutants enters the rainwater pipes through the rainwater inlets and is directly discharged into nearby rivers and lakes, which will cause certain degrees of harm to the rivers and lakes. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a prefabricated rainwater inlet to solve the technical problem that the existing rainwater inlets have no ability to intercept pollutants in the initial rainwater. The initial rainwater carrying pollutants enters the rainwater pipe through the rainwater inlet and is directly discharged into the nearby rivers and lakes, which will cause certain damage to the rivers and lakes.

[0005] To achieve the above-mentioned technical objectives, the present invention provides a prefabricated rainwater inlet, including a well chamber, which is hollow inside and has an open top structure. A grate is provided at the top opening of the well chamber. The well chamber is characterized by having a guide plate rotatably mounted inside, and a rainwater pipe and a sewage pipe communicating with the inside of the well chamber on the side wall of the well chamber. By rotating the guide plate, the lower end of the guide plate can be aligned with the rainwater pipe or the sewage pipe.

[0006] Furthermore, the inner walls of the well are both arc-shaped structures on opposite sides, and the two sides of the guide plate are respectively attached to the opposite sides of the inner walls of the well.

[0007] Furthermore, a first water-blocking block is provided at the bottom of one end of the rainwater pipe located inside the manhole; a second water-blocking block is provided at the bottom of one end of the sewage pipe located inside the manhole.

[0008] Furthermore, a rotating shaft is provided at the central axis of the guide plate, with both ends of the rotating shaft rotatably connected to the two sides opposite the well chamber, and a drive rod is vertically installed on the rotating shaft.

[0009] Furthermore, the grate is provided with several strip-shaped through holes, and the upper end of the drive rod passes through one of the strip-shaped through holes and extends out from inside the well chamber.

[0010] Furthermore, the grate is equipped with pin sleeves at both ends of one of the strip-shaped through holes, and the upper end of the drive rod is equipped with a pin hole. The pin sleeves and the pin hole of the drive rod are equipped with pins.

[0011] The beneficial effects of this utility model include: This utility model provides a prefabricated rainwater inlet. In the initial stage of rainfall, the guide plate is rotated to its lower end opposite the sewage pipe. Rainwater entering the manhole can fall onto the guide plate and flow along the guide plate into the sewage pipe. After a period of rainfall, the guide plate is rotated to its lower end opposite the rainwater pipe. Rainwater entering the manhole can fall onto the guide plate and flow along the guide plate into the rainwater pipe. Therefore, it can prevent the initial rainwater carrying pollutants from entering the rainwater pipe through the rainwater inlet and being directly discharged into nearby rivers and lakes, thereby avoiding certain degrees of harm to the rivers and lakes.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] This utility model embodiment provides a prefabricated rainwater inlet, including a well chamber 1, which is hollow inside and has an open top. A grate 2 is provided at the top opening of the well chamber 1. A guide plate 3 is rotatably installed inside the well chamber 1. A rainwater pipe 4 and a sewage pipe 5, which communicate with the inside of the well chamber 1, are provided on the side wall of the well chamber 1. By rotating the guide plate 3, the lower end of the guide plate 3 can be aligned with the rainwater pipe 4 or the sewage pipe 5. At the beginning of rainfall, the guide plate 3 is rotated so that its lower end is aligned with the sewage pipe 5, allowing water to enter the well chamber. Rainwater inside the manhole 1 can fall onto the guide plate 3 and flow along the guide plate 3 into the sewage pipe 5. After a period of time, the guide plate 3 is rotated to its lower end opposite the rainwater pipe 4. Rainwater entering the manhole 1 can fall onto the guide plate 3 and flow along the guide plate 3 into the rainwater pipe 4. Therefore, it can prevent the initial rainwater carrying pollutants from entering the rainwater pipe 4 through the rainwater inlet and being directly discharged into the nearby river and lake water bodies, thereby avoiding certain degrees of harm to the river and lake water bodies.

[0018] It should be noted that the sewage pipe 5 is located below the rainwater pipe 4. When the guide plate 3 is rotated to its lower end opposite the sewage pipe 5, the tilt angle of the guide plate 3 is relatively large, which can facilitate the flow of impurities such as mud and sand in the rainwater into the sewage pipe 5.

[0019] It should be noted that the inner walls of the well chamber 1 have arc-shaped structures on both sides, which ensures that the sides of the guide plate 3 are always in contact with the inner walls of the well chamber 1 during the rotation process. At the same time, the guide plate 3 is equipped with sealing strips on its four sides to prevent rainwater from overflowing between the guide plate 3 and the well chamber 1, thereby improving the diversion effect.

[0020] In this embodiment, a first water-blocking block 41 is provided at the bottom of one end of the rainwater pipe 4 inside the well chamber 1. The first water-blocking block 41 can prevent the clean water flowing into the rainwater pipe 4 from flowing back into the well chamber 1. A second water-blocking block 51 is provided at the bottom of one end of the sewage pipe 5 inside the well chamber 1. The second water-blocking block 51 can prevent the sewage flowing into the sewage pipe 5 from flowing back into the well chamber 1.

[0021] In this embodiment, a rotating shaft 6 is provided at the central axis of the guide plate 3. The two ends of the rotating shaft 6 are rotatably connected to the two sides opposite to the well chamber 1. A drive rod 7 is vertically installed on the rotating shaft 6. At the same time, the grate 2 is provided with several strip-shaped through holes 21. The upper end of the drive rod 7 passes through one of the strip-shaped through holes 21 and extends out from the inside of the well chamber 1. By rotating the drive rod 7, the rotating shaft 6 can be driven to rotate, and the rotating shaft 6 can drive the guide plate 3 to rotate, which is convenient to operate.

[0022] In this embodiment, the grate 2 is provided with pin sleeves 22 at both ends of one of the strip-shaped through holes 21. The upper end of the drive rod 7 is provided with a pin hole. The pin sleeves 22 and the pin hole of the drive rod are provided with pins 8. When the upper end of the drive rod 7 rotates to one end of one of the strip-shaped through holes 21, the guide plate 3 rotates to its lower end opposite to the rainwater pipe 4. At the same time, the pin hole on the drive rod 7 is opposite to one of the pin sleeves 22. The position of the drive rod 7 can be fixed by the pin 8, thereby preventing the guide plate 3 from rotating when guiding clean water to the rainwater pipe 4. When the upper end of the drive rod 7 rotates to the other end of one of the strip-shaped through holes 21, the guide plate 3 rotates to its lower end opposite to the sewage pipe 5. At the same time, the pin hole on the drive rod 7 is opposite to the other pin sleeve 22. The position of the drive rod 7 can be fixed by the pin 8, thereby preventing the guide plate 3 from rotating when guiding sewage to the sewage pipe 5.

[0023] Specific principle: In the initial stage of rainfall, rotating the drive rod 7 causes the rotating shaft 6 to rotate, which in turn rotates the guide plate 3. The guide plate 3 is rotated until its lower end is aligned with the sewage pipe 5. Then, the drive rod 7 is fixed to the grate 2 by the pin 8 to secure the position of the guide plate 3. Rainwater entering the manhole 1 falls onto the guide plate 3 and flows along it into the sewage pipe 5. After the rainfall has stopped for a while, the pin 8 is released, and the drive rod 7 is rotated in the opposite direction, causing the rotating shaft 6 to rotate. The rotating shaft 6 drives the guide plate 3 to rotate, rotating the guide plate 3 until its lower end is opposite to the rainwater pipe 4. Then, the drive rod 7 is fixed to the grate 2 by the pin 8 to fix the position of the guide plate 3. The rainwater entering the well chamber 1 can fall onto the guide plate 3 and flow along the guide plate 3 into the rainwater pipe 4. Therefore, it can prevent the initial rainwater carrying pollutants from entering the rainwater pipe 4 through the rainwater inlet and being directly discharged into the nearby river and lake water bodies, thereby avoiding a certain degree of harm to the river and lake water bodies.

[0024] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
