Description

Technical Field

[0001] This utility model is a rainwater inlet filtration device, belonging to the field of municipal engineering. Background Technology

[0002] In municipal road construction, prefabricated drainage ditches are typically laid between the two layers of the road structure to ensure smooth drainage. These prefabricated drainage ditches are continuously laid along the road's extension direction, forming a drainage channel that runs throughout the entire length of the road. The tops of the prefabricated drainage ditches are neatly overlapped with cover plates, some of which have several inlets evenly distributed on their surfaces, allowing rainwater to flow smoothly into the ditch. The cover plates with inlets act as filters. However, dirt, sand, and other impurities from the road can enter the prefabricated drainage ditches along with the rainwater through these inlets. When the water flow in the prefabricated drainage ditches is slow, these impurities gradually settle, forming a thick layer of sediment at the bottom. Traditionally, cleaning this sediment requires lifting each cover plate one by one to sweep or remove the sediment from the prefabricated drainage ditches. However, the cover plates are often heavy and need to cover the entire top of the prefabricated drainage ditch. Lifting and moving the cover plates is not only laborious, but also adds extra steps and time to the cleaning work, which greatly increases the workload of maintenance personnel and affects the maintenance efficiency of the road drainage system. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rainwater inlet filtration device to solve the problems mentioned in the background art. This utility model can handle sediment without moving the cover plate, thus reducing the workload.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rainwater inlet filtration device, comprising: A prefabricated drainage ditch, wherein both ends of the prefabricated drainage ditch are equipped with overlapping parts, and the upper surface of the two overlapping parts is recessed downward on the side facing the central area of ​​the prefabricated drainage ditch to form an overlapping groove. A cover plate is set in the space formed by two overlapping grooves on a prefabricated drainage ditch. Multiple water inlets are evenly opened on the upper surface of the cover plate, and a through hole is processed in the middle of one side of the upper surface of the cover plate. A pipe joint is installed in the middle of an overlap groove of the prefabricated drainage ditch. The pipe joint is threaded with an internal thread cap. The pipe joint passes through the opening, and the internal thread cap is located on the upper side of the opening. The connecting pipe is connected to the pipe joint at its upper end, and a straight pipe is installed at the end of the connecting pipe away from the pipe joint. Both the straight pipe and the connecting pipe are anchored in the prefabricated drainage ditch. Multiple flushing components are provided, and these multiple flushing components are evenly installed on the outer surface of the straight pipe for filling the prefabricated drainage ditch with water.

[0005] Furthermore, the flushing component includes a sleeve, and multiple sleeves are evenly installed on the upper part of the outer surface of the straight pipe. The upper end of the sleeve is open, and a cap is fitted onto the sleeve and adhered to it. Multiple small holes are evenly opened on the upper surface of the cap. The cap is set in the prefabricated drainage ditch and the upper end of the cap is flush with the bottom of the prefabricated drainage ditch. A rubber sheet is provided in the upper part of the sleeve. A cross slit is opened on the upper surface of the rubber sheet. A perforated disc is provided on the lower side of the rubber sheet. The edge of the rubber sheet is adhered to the perforated disc with glue. Multiple short rods are evenly fixed on the side of the perforated disc away from the rubber sheet. The lower ends of the short rods are in contact with the bottom of the sleeve.

[0006] Furthermore, a connecting sleeve is fitted onto one end of the connecting pipe near the straight pipe, and two symmetrically arranged stabilizing rods are fixedly connected to the outer surface of the connecting sleeve.

[0007] Furthermore, the outer surface of the ring is recessed to form two symmetrically arranged blind holes, and one end of the stabilizing rod is installed in the blind holes.

[0008] Furthermore, a side ring is fixed to the lower end of the cap, and a circular ring is provided on the upper side of the side ring. The circular ring is sleeved on the cap, and multiple positioning rods are fixed at equal intervals on the outer surface of the circular ring. The circular ring and positioning rods are all set in the prefabricated drainage ditch.

[0009] Furthermore, a plurality of snap-fit ​​parts are installed on the lower part of one side of the prefabricated drainage ditch, and a plurality of snap-fit ​​grooves are formed on the side of the prefabricated drainage ditch opposite to the snap-fit ​​parts. A snap-fit ​​part on one prefabricated drainage ditch is inserted into a snap-fit ​​groove in another prefabricated drainage ditch.

[0010] Furthermore, the snap-fit ​​part and the prefabricated drainage ditch are integrally formed, the snap-fit ​​part has a rectangular cross-section, and the snap-fit ​​groove has a rectangular cross-section.

[0011] Furthermore, the depth of the overlapping groove is the same as the thickness of the cover plate, and the overlapping part and the prefabricated drainage ditch are integrally formed.

[0012] The beneficial effects of this utility model are: A pipe fitting is inserted into the opening on the cover plate. Normally, an internal threaded cap is screwed onto the pipe fitting to prevent dust and debris from entering the channel formed by the connecting pipe and the straight pipe. When cleaning is needed, the internal threaded cap is removed, and the water supply pipe at the pump outlet is connected to the pipe fitting. After starting the pump, water from the storage container is pumped into the straight pipe. As the water pressure inside the pipe increases, the cross-shaped slits on the rubber sheet are squeezed open, and water is sprayed out through the small holes on the cap. The high-pressure water flow directly washes away sediment in the prefabricated drainage ditch, loosening it and allowing it to flow along the ditch with the water current. The entire process does not require moving the cover plate, greatly simplifying the cleaning steps and reducing workload. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figure 1 and Figure 2This utility model provides a technical solution: a rainwater inlet filtration device, including a prefabricated drainage ditch 1, with overlapping portions 11 installed at both ends of the prefabricated drainage ditch 1. The overlapping portions 11 are integrally formed with the prefabricated drainage ditch 1. The upper surfaces of the two overlapping portions 11 are recessed downwards on the side facing the central area of ​​the prefabricated drainage ditch 1 to form overlapping grooves 12. A cover plate 2 is disposed in the space formed by the two overlapping grooves 12 on the prefabricated drainage ditch 1. The depth of the overlapping grooves 12 is the same as the thickness of the cover plate 2. A plurality of water inlets 21 are evenly provided on the upper surface of the cover plate 2. A through-hole 22 is machined at the middle of one side of the upper surface. Multiple snap-fit ​​parts 13 are installed at the lower part of one side of the prefabricated drainage ditch 1. The snap-fit ​​parts 13 are integrally formed with the prefabricated drainage ditch 1, and the cross-section of the snap-fit ​​parts 13 is rectangular. The side of the prefabricated drainage ditch 1 away from the snap-fit ​​parts 13 is recessed to form multiple snap-fit ​​grooves 14 that cooperate with the snap-fit ​​parts 13. The cross-section of the snap-fit ​​grooves 14 is rectangular, so that the snap-fit ​​parts 13 on one prefabricated drainage ditch 1 can be inserted into the snap-fit ​​grooves 14 in another prefabricated drainage ditch 1, thus completing the insertion and assembly of two adjacent prefabricated drainage ditches 1.

[0016] See Figures 1-4 A pipe joint 3 is installed in the middle of an overlap groove 12 of the prefabricated drainage ditch 1. An internal thread cap 31 is threaded onto the pipe joint 3. The pipe joint 3 passes through the through-hole 22. The internal thread cap 31 is located on the upper side of the through-hole 22. After the pipe joint 3 passes through the through-hole 22, the internal thread cap 31 is screwed on, thereby restricting the relative position of the cover plate 2 and the prefabricated drainage ditch 1.

[0017] The upper end of the connecting pipe 32 is connected to the pipe joint 3. A straight pipe 33 is installed at the end of the connecting pipe 32 away from the pipe joint 3. Both the straight pipe 33 and the connecting pipe 32 are anchored in the prefabricated drainage ditch 1. A connecting sleeve 5 is fitted on the end of the connecting pipe 32 near the straight pipe 33 and is fixed to the connecting pipe 32. Two symmetrically arranged stabilizing rods 51 are fixed to the outer surface of the connecting sleeve 5. The outer surface of the connecting sleeve 5 is recessed to form two symmetrically arranged blind holes, so that one end of the stabilizing rod 51 is installed in the blind hole, increasing the connection range between the stabilizing rod 51 and the connecting sleeve 5. The stabilizing rod 51 is connected to the steel bars in the prefabricated drainage ditch 1 by using tie wire, so as to restrict the position of the connecting pipe 32 by using the steel bars in the prefabricated drainage ditch 1.

[0018] See Figures 1-6Multiple sleeves 42 are evenly installed on the upper part of the outer surface of the straight pipe 33. The upper end of the sleeve 42 is open. A cap 4 is attached to the sleeve 42 and is evenly opened on the upper surface of the cap 4. The cap 4 is set in the prefabricated drainage ditch 1 and the upper end of the cap 4 is flush with the bottom of the prefabricated drainage ditch 1. A rubber sheet 41 is provided in the upper part of the sleeve 42. A cross slit is opened on the upper surface of the rubber sheet 41. A perforated plate 43 is provided on the lower side of the rubber sheet 41. The edge of the rubber sheet 41 is glued to the perforated plate 43. The perforated disc 43 is bonded together. Multiple short rods 44 are evenly fixed to the side of the perforated disc 43 facing away from the rubber sheet 41. The lower ends of the short rods 44 contact the bottom of the inner sleeve 42. A pipe connector 3 is tightly inserted into the through-hole 22 on the cover plate 2. Normally, an internal threaded cap 31 is screwed onto the pipe connector 3 to prevent dust, gravel, fallen leaves, and other debris from entering the water supply channel formed by the connecting pipe 32 and the straight pipe 33, ensuring the channel remains unobstructed and does not affect subsequent use due to blockage. When it is necessary to clean the sediment in the prefabricated drainage ditch 1, simply unscrew the internal threaded cap 31 and connect the water supply pipe at the pump outlet to the pipe connector 3. After starting the pump, water from the storage container is continuously pumped into the straight pipe 33 along the pipe. As water continues to be injected, the water pressure in the straight pipe 33 gradually increases. When the pressure reaches a certain level, it will naturally squeeze the cross-shaped seam on the rubber sheet 41, causing the originally closed seam to slowly open. The water can then flow through this seam to the cap 4 and finally spray out at high speed from the small hole on the cap 4.

[0019] These high-pressure water jets directly impact the sediment in the prefabricated drainage ditch 1, using their impact force to completely loosen and break up the hardened mud and accumulated sand. The dispersed sediment will flow naturally along the direction of the prefabricated drainage ditch 1 with the water flow. Throughout the cleaning process, the cover plate 2 remains firmly on the prefabricated drainage ditch 1 without the need for laborious lifting or moving. This eliminates the tedious steps of moving the cover plate 2 and reduces the physical exertion from repeated operations, making the cleaning work more efficient and less strenuous.

[0020] See Figures 3-5 The lower end of the cap 4 is connected and fixed with a side ring 45. A circular ring 47 is provided on the upper side of the side ring 45, and the circular ring 47 is fitted onto the cap 4. Multiple positioning rods 46 are fixed at equal intervals on the outer surface of the circular ring 47. Both the circular ring 47 and the positioning rods 46 are installed inside the precast drainage ditch 1. During the precast concrete drainage ditch 1, components such as the straight pipe 33 and connecting pipe 32 are integrally cast into the concrete, ensuring these structures are firmly embedded in the precast drainage ditch 1. Simultaneously, the fixing structure formed by the circular ring 47 and the positioning rods 46 is also cast and fixed at the same time. By expanding the bonding range with the concrete, the anchoring effect of the cap 4 is enhanced, making the cap 4 more securely installed within the precast drainage ditch 1 and less prone to loosening or displacement.

[0021] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
