Description
Technical Field
[0001] This utility model relates to the field of urban water supply and drainage technology, and in particular to a rainwater diversion well for side ditches. Background Technology
[0002] Currently, during the construction of municipal roads, the issue of rainwater outlet for roadbed drainage ditches needs to be considered. Usually, rainwater from the side ditches is connected to the municipal rainwater pipes. In extreme rainfall weather such as heavy rain or torrential rain, rainwater will be mixed with various substances, which can easily cause blockages and affect the rainwater diversion capacity, making it easy to cause waterlogging. Existing rainwater wells mostly use screens to intercept dirt. However, the screens are not easy to clean automatically, which leads to dirt accumulation and screen blockage, resulting in poor rainwater diversion effect. Summary of the Invention
[0003] To overcome the problems existing in related technologies, this utility model provides a rainwater diversion well for side ditches, which uses rainwater to drive a floating body to move on the grid, which can clear blockages on the grid and ensure the rainwater diversion effect of the diversion well.
[0004] This utility model provides a rainwater diversion well for a side ditch, including a well body with an inlet, a waterway and an outlet that are interconnected. The waterway is equipped with a filter screen and a float. The filter screen has multiple vertically arranged flow channels. The float moves from the first end to the second end of the flow channel under the action of buoyancy.
[0005] In some embodiments, the filter grid includes a frame, within which a plurality of vertically extending grid strips are provided.
[0006] In some embodiments, the grid strips are cylindrical with a diameter of 10 mm and a spacing of 100 mm between adjacent grid strips.
[0007] In some embodiments, the float includes an arc-shaped grid and a plurality of buoys. The buoys are provided on a first side of the arc-shaped grid, and the second side of the arc-shaped grid is rotatably connected to the inner wall of the waterway. The arc-shaped grid has a plurality of vertically arranged and parallelly spaced grid bars, which are located inside the flow channel. Under the action of buoyancy, the grid bars pass through the flow channel.
[0008] In some embodiments, the second side of the arc-shaped grille is provided with an outwardly extending connecting rod, the end of the connecting rod is provided with a limiting structure, and the connecting rod is fitted with a ring, the ring being connected to the inner wall of the waterway.
[0009] In some embodiments, the filter grille is inclined within the waterway.
[0010] In some embodiments, the waterway includes a first chamber and a second chamber that are interconnected, the first chamber being connected to an inlet, the second chamber being connected to the middle of the first chamber, the second chamber being connected to an outlet, and the filter screen being located between the first chamber and the second chamber.
[0011] In some embodiments, the bottom of the first chamber is a sedimentation zone, the first chamber is detachably equipped with a mesh bag, the mesh bag divides the first chamber into a flow guiding zone and a sedimentation zone, and a guide ramp is provided between the first chamber and the second chamber, the guide ramp connecting to the sedimentation zone.
[0012] In some embodiments, the bottom of the well body is provided with a base plate, the bottom of the base plate is provided with a plain concrete pad, and the middle side wall of the well body is connected to a pipe, which is connected to a municipal rainwater pipe.
[0013] The technical solution provided by this utility model can include the following beneficial effects: The rainwater diversion well provided by this utility model has an inlet for laying rainwater grates and an outlet connected to the municipal rainwater pipe. During extreme rainfall events such as heavy rain or storms, when rainwater mixed with debris such as leaves, branches, and plastic bags flows through the waterway and stagnates against the filter screen, a float rises in the rainwater under buoyancy and moves from one end of the flow channel to the other, effectively clearing the flow through the filter screen. This rainwater diversion well not only ensures a smooth connection between the ditch and the rainwater pipe but also prevents pipe blockage caused by debris entering the pipe. It features a simple and reasonable structure, is easy to use, and effectively guarantees the diversion effect of rainwater. Attached Figure Description

[0017] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.
[0018] In the description of the utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0019] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0020] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0021] like Figures 1 to 4 As shown in the figure, the rainwater diversion well for a side ditch provided by this utility model includes a well body 1, which has an inlet, a water channel and an outlet that are interconnected. The water channel is provided with a filter screen 2 and a float 3. The filter screen 2 has multiple vertically arranged flow channels. The float 3 moves from the first end to the second end of the flow channel under the action of buoyancy.
[0022] A drainage ditch is dug along the side of the municipal road. Below the drainage ditch, a well body 1 (as described in this embodiment) is excavated. The well body 1 is made of concrete, with an inlet at the top that connects to the drainage ditch. A storm drain grate is laid on the drainage ditch. The well body 1 has a waterway for rainwater passage, and a filter screen 2 is installed on the waterway. The flow channel of the filter screen 2 runs through the waterway and connects to an outlet, which connects to the municipal stormwater pipe. The float 3 has a density less than that of water. When water flows in the waterway, the float 3 floats on the surface. Under different flow rates, the float 3 moves within the flow channel. In extreme rainfall events such as heavy rain or storms, when rainwater mixed with debris such as leaves, branches, and plastic bags flows through the waterway and stagnates in the filter screen 2, the float 3, under the influence of buoyancy, rises in the rainwater and moves from one end of the flow channel to the other, scraping away the debris trapped in the screen and thus clearing the flow channel of the filter screen 2. After clearing debris from the channel, the flow rate increases, and float 3 descends. When the channel is blocked by debris or submerged in water, float 3 rises. This side ditch rainwater diversion well not only ensures a smooth connection between the side ditch and the rainwater pipe, but also prevents pipe blockage caused by debris entering the pipe. It features a simple and reasonable structure, is easy to use, and effectively guarantees the diversion effect of rainwater.
[0023] like Figure 3 As shown, the filter grille 2 includes a frame, within which several vertically extending grille strips are provided. Adjacent grille strips form a flow channel for rainwater to pass through. When the float 3 moves on the flow channel, it can remove or change the relative position of debris retained in the flow channel, allowing debris such as leaves to pass through the flow channel and enter the municipal stormwater pipe under the impact of water, thus avoiding the problem of clogging of the filter grille 2.
[0024] Furthermore, the grid strip has a cylindrical structure and a diameter of 10mm. The spacing between adjacent grid strips is 100mm. The material of the grid strip can be steel pipe or plastic pipe with certain corrosion resistance. In some embodiments, the grid strip is Q235A steel pipe.
[0025] like Figure 4As shown, the float 3 includes an arc-shaped grid 31 and several floats 32. The floats 32 are located on the first side of the arc-shaped grid 31, and the second side of the arc-shaped grid 31 is rotatably connected to the inner wall of the waterway. The arc-shaped grid 31 has multiple vertically arranged and parallelly spaced grid rods 33, which are located inside the flow channel. Under the action of buoyancy, the grid rods 33 pass through the flow channel. The grid rods 33 are arranged in an arc shape. When there is no rainwater flow in the diversion well or the rainwater flow is small, the floats 32 are located at the bottom of the waterway. At this time, part of the grid rods 33 passes through the flow channel of the filter grid 2 and is exposed on the filter grid 2. That is to say, the two ends of the grid rods 33 face the outlet. With this arrangement, the debris stuck on the surface of the filter grid 2 can be effectively moved or removed, and the relative position of the debris can be changed so that it can pass through the flow channel and enter the municipal rainwater pipe under the flow of rainwater, thus avoiding the problem of blockage of the filter grid 2 and causing waterlogging.
[0026] Furthermore, the second side of the arc-shaped grille 31 is provided with an outwardly extending connecting rod 34, the end of the connecting rod 34 is provided with a limiting structure, and the connecting rod 34 is fitted with a ring 35, the ring 35 being connected to the inner wall of the waterway.
[0027] Furthermore, the filter grille 2 is inclinedly installed in the waterway, with one end of the filter grille 2 facing the bottom of the waterway close to the outlet, and the other end facing the bottom of the waterway away from the outlet. The inclined filter grille 2 can reduce and prevent debris from getting stuck on the filter grille 2. After the water volume of the rainwater diversion well in the side ditch is reduced, the debris stuck in the filter grille 2 can fall off by its own gravity.
[0028] Furthermore, the waterway includes a first chamber and a second chamber that are interconnected. The first chamber is connected to the inlet, the second chamber is connected to the middle of the first chamber, and the second chamber is connected to the outlet. The filter screen 2 is located between the first chamber and the second chamber.
[0029] Furthermore, the bottom of the first chamber is a sedimentation zone, and the first chamber is detachably equipped with a mesh bag 4. The mesh bag 4 divides the first chamber into a diversion zone and a sedimentation zone. A guide slope 7 is provided between the first chamber and the second chamber. The guide slope 7 connects to the sedimentation zone. After the garbage and debris on the grid falls onto the guide slope 7, it enters the mesh bag 4 in the sedimentation zone along the guide slope 7. The mesh bag 4 is hung on a hook bolt, which is installed on the inner side wall of the well body 1. The mesh bag 4 is detachably installed on the well body 1, which facilitates regular maintenance and ensures the normal use of the diversion well.
[0030] Furthermore, the bottom of the well body 1 is provided with a base plate 5, the bottom of the base plate 5 is provided with a plain concrete pad 6, the middle side wall of the well body 1 is connected to a pipe, the pipe is connected to a municipal rainwater pipe, and the base plate 5 and the well body 1 are integrally cast with concrete.
[0031] In summary, after rainwater enters the diversion well of the ditch, sand and small debris pass through the mesh bag 4 and settle in the sedimentation area. During extreme weather events such as heavy rain, as the water level rises, the float 32 rises under the thrust and buoyancy of the water flow, causing the grid bar 33 to move along the flow channel of the filter grid 2. Lighter debris such as leaves and plastic bags are intercepted by the filter grid 2. As rainfall decreases and the water level drops, the float 3 and float 32 descend under their own weight, removing debris remaining in the flow channel. The continuous changes in rainwater flow cause the water level to rise and fall, allowing the float 3 to move back and forth within the flow channel of the filter grid 2, removing leaves, plastic bags, and other debris from the grid, preventing blockage of the diversion well, and ensuring smooth drainage of the rainwater pipes.
[0032] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
